1 Tablet type diversification requirements analysis
1.1 Tablet type diversification and suppression methods
For tablet manufacturers, their products are no longer a single round tablet, but with a variety of diverse requirements.
(1) According to the shape, it can be divided into a series of various requirements such as ring, square, trapezoid, ellipse, triangle, sphere, petal shape, deep concave and shallow concave. In order to achieve the suppression of these tablet products, the die needs to be customized according to the user's tablet product, and most of them are non-standard die. It is customary to press a die of a non-circular tablet such as a square, a trapezoid, a triangle, a petal shape, etc. For the die, the upper punch of this type of die needs to be configured with an orientation key, and the upper punch hole of the turntable needs to process the keyway to cooperate with the punch to complete the pressing of the tablet.
(2) According to the color, it can be divided into a monochrome film, a two-color film, and the like. The monochromatic film is pressed with a material. The two-color film requires two materials (that is, the two materials are pressed into one tablet, but the layers and colors are distinct), and to achieve the pressing of the two-color film, the tablet press is required. The undercut rail system is modified to achieve two fillings and one sheet at a time. Among them, if a special film taking device is added, the content of one of the materials can be measured to control the ratio of the two materials of the tablet.
(3) According to the word, it can be divided into Chinese characters, letters, and graphics. The suppression of the tablet is also made according to the sample of the user's tablet product, and the corresponding Chinese characters or graphics are processed on the die to realize the tablet pressing.
(4) According to the size of the shape, it can be divided into standard shape size and large size. For large-sized tablet products, it is necessary to order large-size die, and to modify the structure of the tablet press, mainly to transform the filling adjustment system, pressure regulation system, guide rail system and turntable.
1.2 Diversification requirements of the structure of the tablet press
In the user's customized order, the structural diversification requirements are mainly reflected in the following aspects:
(1) In the filming method, it is required to have a single-sided film, a double-sided film, and a single-sided film, and a double-sided film. This requires designing and transforming the sheet structure of the tablet press to achieve different requirements.
(2) In terms of protection, it is required to have a break protection structure and automatic power-off protection when the tablet door is opened. 1) The breaking protection structure means that when the ram suddenly breaks under the accident, the breaking protection system reacts quickly, the equipment immediately stops automatically, prevents the occurrence of a safety accident, eliminates the hidden danger in the bud; 2) When opening the tablet door The automatic power-off protection means that the tablet press can not be operated in the state where the tablet door is opened. When the tablet press is in normal operation, the tablet door is opened and the machine is automatically stopped quickly. This requires a dual design modification of the mechanical and electrical parts, and the detection signal is passed to the electrical control system to achieve automatic protection control.
(3) There are special requirements for the structure and material of some parts. For example, some users' tablet products have explosion-proof requirements, and the tablet chamber door is required to be made of stainless steel, which is durable and corrosion-resistant. It is required to use a glued wood material to avoid interaction with materials.
(4) In terms of operation control, most of the tablet press's operating system and host are integrated, but there are also requirements for the operating system to be independent and can be operated from a distance. According to the user's requirements, the electrical operating system is designed and modified, and the independent electrical cabinet is designed and processed. The operating system and the independent electrical cabinet are connected together by the cable, thus realizing the remote operation control.
2 Â Â Â Â Â Â Â Â Special requirements of tablet press structure and use requirements analysis
The tablet press with special requirements has its own specific structure, and the use requirements also need attention. The following is a summary of several common models.
2.1 Analysis of the structure and use requirements of the tablet press using a profiled die
Tablets pressed using a profiled die have clear positioning requirements for the die during pressing, such as square, trapezoidal, triangular, elliptical, polygonal, etc., non-circular shapes. The requirements for the structure of the tablet press are mainly the upper punch hole processing keyway of the turntable (for positioning the upper punch), and the requirement of the punching die is that the upper punch needs to have an orientation key, so that it can be mounted on the turntable during installation. The punch holes are matched. In the process of pressing, the lower punch does not leave the middle die hole, and its positioning and coordination is clear, so no special processing is needed.
When the tablet is pressed by the special die, the punch can not be freely rotated in the punch hole, and can only be moved up and down along the upper and lower rails, and at the same time, the sliding friction is generated by the turntable and the guide rail, which exacerbates the punching. Wear of the rods and rails and wear of the rams and turrets. Therefore, in the process of use, pay great attention to the lubrication of the punch and the guide rail, forming a daily maintenance system; the keys of the punch should also be checked regularly, if the loose keys will cause the keys and the keyway and the punch and the punch hole to wear, It affects the positioning requirements of the punch for the middle die. In severe cases, it will damage the punch and the middle die and cannot be produced normally.
When installing the special die, firstly, the punch and the middle die should be positioned accurately. After the punch is free to enter the middle die, the middle die can be fastened to prevent the punch and the middle die from being “bited†due to inaccurate positioning. After all the dies are installed, apply the handwheel for a few laps, no abnormalities, and then run the power.
2.2 Analysis of the structure and use requirements of the two-color tablet press
The two-color tablet press machine presses two different materials into one tablet, and the two materials are separated from each other and the color is distinct, so that the pressing of the two-color tablet is mainly carried out on the structure of the tablet press to realize the design and transformation of the lower guide rail. Fill twice, one at a time.
The main situations that occur during the process of pressing the two-color film are as follows: (1) The content of the two materials on the same tablet does not meet the requirements. This is mainly because the filling adjustment system is not adjusted well, and the content of one material can be adjusted first. Then adjust the content of another material; (2) The two materials extruded from the tablet have a fragmentation phenomenon, the hardness is uneven, one material is hard, and one material is soft. The main reasons are: 1) the reason of the material, The density, dryness and uniformity of the two materials were not adjusted well, and the materials were adjusted and then pressed; 2) the pressure of the two materials was not adjusted well, and the principle of the two-color film was double-filled, once into pieces. If the pressure is not adjusted after *filling, the hardness of the lower half is hard or soft. After the second filling, the pressure is set for a whole tablet, so the adjustment of the pressure determines the degree of tableting and bonding. .
The two-color tablet press generally needs to be equipped with two vacuum cleaners, which can separately absorb the two materials and recycle them. If the user has precise requirements on the composition of the two materials, the tablet press can be provided with a separate piece for the tablet extruded from one of the materials, and the measurement can be accurately measured to determine the content.
2.3 Ring sheet tablet press structure and use requirements analysis
The tablet extruded by the ring press is a ring shape, the main structure is on the die, the hole is machined in the middle of the punch, the core rod is processed, and the groove is machined on the side; the structure of the tablet press is changed on the die hole in the turntable. A press plate is added to cooperate with the die to complete the pressing of the annular piece (the installation of the annular piece die is more complicated than the installation of the ordinary tablet press die).
2.4 Analysis of the structure and use requirements of the tablet press with explosion-proof requirements
Explosion-proof tablet presses are mainly used in military, automotive and other industries. The pressed tablets are inflammable and explosive products, and the structure and material of the tablet press are required to meet the explosion-proof requirements. Taking the rotary sub-high-speed tablet press ZPYGS51 produced by our company as an example, the main motor and feeding motor used are explosion-proof motors, and the electrical cabinets are designed independently. The operating system and the electrical cabinet are displayed together to realize long-distance operation. The pipeline is connected with the main engine in accordance with the explosion-proof requirements; the die adopts the I series, and the turntable has good guiding; the rotary table is equipped with an interrupt protection system; the filling pressure regulating system is equipped with a locking device; the display operating system realizes filling, Display or setting of pressure, preload, production, fault and parameter adjustments.
3 Introduction of tablet press
In addition to the general-purpose series of products, the tablet presses produced by Liaocheng Wanhe Industrial Manufacturing Co., Ltd. are ordered and customized according to the special requirements of users. The following are the classification and analysis of the parameters of the company's tablet presses, as shown in Table 1. Show.
