Description

Technical Field

[0001] This utility model belongs to the field of tablet punching machine technology, and in particular to a single-pressure tablet punching machine for pharmaceuticals. Background Technology

[0002] When conducting tests on pharmaceutical granules, the raw materials need to be made into solid sheets of a certain thickness. Then, pharmaceutical test pieces are stamped out from the solid sheets using a stamping machine and corresponding molds. Finally, the performance of the pharmaceutical test pieces is tested.

[0003] Existing pharmaceutical single-press tablet machines produce solid tablets of varying sizes for different drugs. During the pressing process, these solid tablets are prone to warping and breaking, reducing efficiency.

[0004] For example, in a punching machine (authorization announcement number CN209304722U), the die, through the cooperation of a ball-head spring plunger and a positioning groove, further enhances the connection strength between the die and the punching head. The punching head, by incorporating a discharge assembly, eliminates the need to remove the die from the punching head and then retrieve the test piece from the die; simply pressing the push plate of the discharge assembly pushes the test piece out of the die, facilitating its removal. However, this device suffers from the problem of failing to effectively secure the thin sheet during use, easily causing warping and breakage during punching, thus reducing efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a single-press tablet press for pharmaceuticals to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pharmaceutical single-press tablet punching machine, comprising: a platform and a fixed plate disposed at the top of the platform; a first linear motor is mounted on the vertical side of the fixed plate, a moving block is fixed to the driving end of the first linear motor, a top plate is mounted on the top of the moving block, two connecting plates are vertically fixed to the bottom of the top plate, a second linear motor is mounted between the two connecting plates, a cylinder is mounted on the driving end of the second linear motor, a punch mold for pharmaceutical single-plate punching is mounted on the driving end of the cylinder, two fixed blocks are connected to the bottom of the top plate, telescopic rods are mounted on the sides of the two fixed blocks, four mounting plates are tightly attached between the two connecting plates, threaded grooves are provided on the vertical side of each of the four mounting plates, two square columns are tightly attached between each pair of mounting plates, and two telescopic rods completely penetrate through two of the mounting plates;

[0007] The other two mounting plates are each fixed with a connecting plate on their vertical sides, and the movable part of the telescopic rod is installed on the vertical side of the connecting plate.

[0008] In a further embodiment, four support plates are fixed to the bottom of the platform, and pressing plates are fixed to the bottom of each of the four square columns. Buffer pads are adhered to the bottom of each of the four pressing plates.

[0009] In a further embodiment, the top of the platform is provided with a mounting groove, and a partition is fixed to the vertical inner wall of the mounting groove.

[0010] In a further embodiment, a first motor is mounted on the vertical side of the partition, and a bidirectional lead screw is mounted on the output end of the first motor.

[0011] In a further embodiment, two sliding plates are sleeved around the outer periphery of the bidirectional lead screw, and vertical plates are fixed to the vertical sides of both sliding plates.

[0012] In a further embodiment, a base plate is fixed to the bottom of each of the two vertical plates, and a vertical plate with the same structure is fixed to the top of each of the two base plates.

[0013] In a further embodiment, each of the four vertical plates has a connecting block fixed to its vertical side, and each of the four connecting blocks has a threaded post threaded onto its top.

[0014] In a further embodiment, a turntable is fixed to the top of each of the four threaded posts, a pressing plate is connected to the bottom of each of the four threaded posts, and a clamping plate is fixed to the vertical side of each of the four vertical plates.

[0015] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0016] In operation, this pharmaceutical single-press tablet punching machine uses a first motor located on the side of the partition to control the sliding plate on the outer periphery of the bidirectional lead screw to move in opposite directions, causing the vertical plates on both sides to move synchronously. At the same time, the bottom plates on both sides move closer or further apart, and the turntable is turned so that the threaded column drives the pressing plate to move downward, thereby pressing and fixing the lower mold.

[0017] This pharmaceutical single-press tablet punching machine, during operation, uses a first linear motor located on the side of the fixed plate to drive the moving block and the top plate at the top of the moving block to move up and down, causing the square column to move downwards. Bolts are inserted into the threaded grooves on the mounting plate and the side of the square column, allowing the square column to be fixed during lateral or vertical movement. Subsequently, a telescopic rod located on the side of the fixed block drives the connecting plate to move, causing the mounting plate to move synchronously. This causes the square column to drive the pressing plate to press the four corners of the solid sheet, thus facilitating the fixing of solid sheets of different sizes and preventing the solid sheets from warping and breaking during the punching process, thereby improving efficiency. This pharmaceutical single-press tablet punching machine facilitates the fixing of solid sheets of different sizes, prevents the solid sheets from warping and breaking during the punching process, and improves efficiency.

[0029] Please see Figures 1 to 4 Platform 1 and a fixed plate 14 mounted on top of platform 1 constitute the main body of the device. A first linear motor 7 is mounted on the vertical side of the fixed plate 14. A moving block 26 is fixed to the drive end of the first linear motor 7. A top plate 10 is mounted on the top of the moving block 26. Two connecting plates 8 are vertically fixed to the bottom of the top plate 10. A second linear motor 17 is mounted between the two connecting plates 8. A cylinder 16 is mounted to the drive end of the second linear motor 17. A punch mold for pharmaceutical single-piece stamping is mounted to the drive end of the cylinder 16. Two fixed blocks 9 are connected to the bottom of the top plate 10, and the two fixed blocks 9 are far apart from each other. Telescopic rods 23 are installed on one side. Four mounting plates 24 are tightly attached between the two connecting plates 8. The vertical sides of the four mounting plates 24 are provided with threaded grooves 27. Between the two pairs of mounting plates 24, there are two square columns 12 with the same threaded grooves 27 on their vertical sides. The first linear motor 7, which is set on the side of the fixed plate 14, drives the moving block 26 and the top plate 10 at the top of the moving block 26 to move up and down, so that the square column 12 moves down. Bolts are inserted into the threaded grooves 27 on the sides of the mounting plates 24 and the square column 12, so that the square column 12 can be fixed during the lateral or vertical displacement.

[0030] Subsequently, the telescopic rod 23 set on the side of the fixed block 9 drives the connecting plate 25 to move, causing the mounting plate 24 to move synchronously, thereby causing the square column 12 to drive the pressing plate 28 to press the four corners of the solid sheet, thus facilitating the fixing of solid sheets of different sizes, preventing the solid sheet from warping and breaking during the stamping process, and improving the efficiency of use. Both telescopic rods 23 completely penetrate the two mounting plates 24, and the connecting plate 25 is fixed on the vertical side of the other two mounting plates 24, and the moving part of the telescopic rod 23 is installed on the vertical side of the connecting plate 25.

[0031] Four support plates 20 are fixed to the bottom of the platform 1. Pressing plates 28 are fixed to the bottom of the four square columns 12. Buffer pads 29 are glued to the bottom of the four pressing plates 28. The top of the platform 1 is provided with an installation groove 2. A partition 3 is fixed to the vertical inner wall of the installation groove 2. A first motor 4 is installed on the vertical side of the partition 3. A bidirectional lead screw is installed at the output end of the first motor 4. Two sliding plates 5 are sleeved on the outer periphery of the bidirectional lead screw. Vertical plates 6 are fixed to the vertical sides of the two sliding plates 5.

[0032] The bottom ends of the two vertical plates 6 are fixed with base plates 21, and the top ends of the two base plates 21 are fixed with vertical plates 6 of the same structure. The vertical sides of the screw vertical plates 6 are fixed with connecting blocks 15. The top ends of the four connecting blocks 15 are threaded with threaded posts 19. The top ends of the four threaded posts 19 are fixed with turntables 13. The bottom ends of the four threaded posts 19 are connected with pressing plates 18. The vertical sides of the four vertical plates 6 are fixed with clamping plates 22. The buffer pads 29 are made of plastic.

[0033] The first linear motor 7, the first motor 4, the second linear motor 17, the cylinder 16, and the telescopic rod 23 are all conventional instruments. Their working principles, dimensions, and models are irrelevant to the function of this application, so they will not be described in detail. The control method of this utility model is controlled by a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0034] Working principle

[0035] In operation, the pharmaceutical single-press tablet punching machine uses a first linear motor 7 located on the side of the fixed plate 14 to drive the top plate 10 to move up and down. Bolts are inserted into the threaded grooves 27 on the sides of the mounting plate 24 and the square column 12 to fix the square column 12 during lateral or vertical displacement. Then, the telescopic rod 23 located on the side of the fixed block 9 drives the connecting plate 25 and the mounting plate 24 to move, so that the pressing plate 28 drives the buffer pad 29 to press the solid sheet. The cylinder 16 drives the punch die to punch the solid sheet, so that the punch die punches out the pharmaceutical test tablet.
