[0004] During operation, the device uses a motor and a pusher plate to feed the pressed tablets, effectively increasing the feeding speed. After the tablets are fed, granular or powdered materials are placed on the surface of the lower template for feeding. The feeding and feeding process takes a certain amount of time, which results in a long interval between the two pressing operations and a low pressing efficiency.

[0005] Therefore, it is necessary to invent a continuous tableting machine for granular materials to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a continuous tablet press for granular materials to solve the problem that the feeding and unloading process in the technology requires a certain amount of time, which leads to a long interval between two pressing operations and thus low pressing efficiency.

The hydraulic cylinder pushes the upper template downward to press the material on the surface of the lower template. After pressing, the servo motor moves the lower template to the left to unload the material, while the lower template on the right side moves to the lower side of the upper template. While the material is unloaded from the left template, the right template is pressed. This process is repeated, effectively increasing the speed of unloading and loading, reducing the interval time between two pressing operations, and improving the pressing efficiency of the equipment.

[0017] Optionally, both ends of the equipment platform are rotatably connected to transmission rods, and the two sets of transmission wheels are coaxially and fixedly connected to the two sets of transmission rods respectively.

[0018] Optionally, the servo motor is fixedly installed on the right end of the front surface of the equipment platform, and the output end of the servo motor is fixedly connected to the front end of the right transmission rod.

[0019] By adopting the above technical solution, the output end of the servo motor drives the right transmission rod to rotate, the right transmission rod drives the right transmission wheel to rotate, and in turn drives the transmission belt to rotate.

[0020] Optionally, multiple sets of transmission rods are fixedly connected to the surface of the transmission belt, and the connecting groove is opened on the lower surface of the lower template, with the transmission rods being engaged inside the connecting groove.

[0021] By adopting the above technical solution, the transmission belt rotates and drives the transmission rod to slide, thereby causing the lower template to slide on the surface of the equipment platform.

[0022] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0023] 1. This utility model employs multiple sets of lower templates in coordination, and uses a servo motor to drive the conveyor belt to transport the lower templates to the lower side of the upper template for pressing. While feeding, the pressed tablets and the lower templates move to the left. During the pressing process, the tablets pressed on the left are unloaded, and the lower template containing granules or powder is clamped on the upper side of the right transmission rod, so as to continuously press the material on the surface of the lower template, effectively improve the feeding and unloading speed, reduce the time interval between two pressings, improve tablet pressing efficiency, and achieve uninterrupted operation.

[0024] 2. This utility model uses a hydraulic cylinder to push the push plate forward, automatically feeding the tablets from the surface of the lower template. At the same time, after the lower template is moved to the leftmost end, the transmission rod will automatically separate from the inside of the connecting slot. When the right set of lower templates slides to the left, it will push the left set of lower templates off the equipment platform. A collection box is set at the left end of the equipment platform to automatically collect the pressed lower templates. Attached Figure Description

[0033] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0034] This utility model provides, for example Figures 1 to 4 The continuous tableting machine for granular materials shown includes a platform 1. A feeding module is provided on the inner side of the platform 1. The feeding module includes a drive shaft 12, drive wheels 13, a drive belt 14, a servo motor 15, a drive rod 16, a lower template 2, and a connecting slot 21. A positioning groove 11 is provided in the middle of the platform 1. Drive wheels 13 are provided on both the left and right sides of the positioning groove 11. The two ends of the drive belt 14 are respectively connected to two sets of drive wheels 13. Drive rods 16 are rotatably connected to both the left and right ends of the platform 1. The two sets of drive wheels 13 are respectively coaxially fixedly connected to the two sets of drive rods 16. The servo motor 15 is fixedly installed at the right end of the front surface of the platform 1. The output end of the servo motor 15 is fixedly connected to the front end of the right drive rod 16. Multiple sets of drive rods 16 are fixedly connected to the surface of the drive belt 14. The connecting slot 21 is opened on the lower surface of the lower template 2, and the drive rods 16 are locked inside the connecting slot 21.

[0035] The servo motor 15 moves intermittently, which in turn drives the lower template 2 on its surface to move intermittently. The lower template 2 is used to place granular or powdery materials for pressing tablets. After the material is placed on the surface of the lower template 2, the connecting groove 21 on the lower surface of the lower template 2 is locked onto the outside of the transmission rod 16. After the material on the surface of the lower template 2 on the left is pressed into tablets, the servo motor 15 drives the right transmission shaft 12 to rotate. The right transmission shaft 12 drives the right transmission wheel 13 to rotate. The two sets of transmission wheels 13 work together to drive the transmission belt 14 to rotate inside the positioning groove 11, which in turn drives the transmission rod 16 to slide to the left on the surface of the equipment platform 1, and at the same time drives the lower template 2 on its surface to slide to the left on the surface of the equipment platform 1.

[0036] See Figure 1 and Figure 5 A device support 3 is fixedly connected to the middle of the upper surface of the device platform 1. A hydraulic cylinder 31 is fixedly installed at the upper end of the device support 3. An upper template 32 is provided on the inner side of the device support 3. A connecting frame 33 is fixedly connected to the upper surface of the upper template 32. The lower end of the telescopic rod in the hydraulic cylinder 31 is fixedly connected to the connecting frame 33. Two sets of positioning rods 34 are provided on both the front and rear sides of the upper template 32. The upper and lower ends of the positioning rods 34 are fixedly connected to the inner top wall of the device support 3 and the upper surface of the device platform 1, respectively. The front and rear ends of the connecting frame 33 are slidably connected to the positioning rods 34 on the front and rear sides, respectively.

[0037] It should be added that when the lower template 2 moves to the lower side of the upper template 32, the servo motor 15 stops running, and at the same time, the output end of the hydraulic cylinder 31 pushes the connecting frame 33 and the upper template 32 downward. The upper template 32 and the lower template 2 cooperate to press the material. When the upper template 32 slides downward, the front and rear ends of the connecting frame 33 slide downward on the surface of the positioning rods 34 on the front and rear sides, which improves the stability of the upper template 32 during the movement.

[0038] See Figure 1 and Figure 6 A mounting plate 4 is fixedly connected to the rear surface of the equipment platform 1 near the left end. A cylinder 41 is fixedly installed in the middle of the rear surface of the mounting plate 4. A push plate 42 is fixedly connected to the front end of the telescopic rod in the cylinder 41. Limiting rods 43 are slidably connected to both the left and right sides of the mounting plate 4. The front end of the limiting rod 43 is fixedly connected to the rear surface of the push plate 42. A guide plate 44 is fixedly connected to the front surface of the equipment platform 1 near the left end.

[0039] In addition, after the material on the surface of the lower template 2 is pressed, the servo motor 15 moves multiple sets of lower templates 2 to the left at the same time, thereby moving the pressed lower template 2 between the mounting plate 4 and the guide plate 44. At this time, the telescopic rod in the cylinder 41 pushes the push plate 42 forward, and the push plate 42 pushes the tablets on the surface of the lower template 2 forward and feeds the tablets through the guide plate 44. The feeding process is carried out synchronously with the pressing process on the right side.

[0040] The working principle of this utility model is as follows: After a set of tablets is compressed and formed, the servo motor 15 drives the transmission belt 14 to rotate, simultaneously moving the lower template 2 after tablet feeding, the lower template 2 for tablet compression, and the lower template 2 for placing materials to the left. The lower template 2 after feeding is moved to the leftmost end, and at the same time, the transmission rod 16 disengages from the connecting slot 21. The lower template 2 for tablet compression moves to the rear side of the guide plate 44, and the lower template 2 for placing materials moves to the lower side of the upper template 32. At this time, the hydraulic cylinder 31 pushes the upper template 32 downwards to cooperate with the lower template 2 in pressing the material. Simultaneously, the cylinder 41 pushes the push plate 42 forward to feed the tablets. The operator then places the tablets in the lower template. The lower template 2 is locked on the upper side of the rightmost transmission rod 16. Then, while the telescopic rod in the hydraulic cylinder 31 and the air cylinder 41 retracts, the servo motor 15 drives the transmission belt 14 to rotate again, which moves the lower template 2 after tablet feeding, the lower template 2 for tablet pressing, and the lower template 2 for placing materials to the left synchronously again. This process is repeated to press the tablets, effectively improving the feeding and unloading speed of materials, enabling the tablet press to operate continuously and improving the tablet pressing efficiency. In addition, during the leftward movement of the lower template 2 after feeding in the second group, it will push the lower template 2 after feeding in the first group off the surface of the equipment platform 1 and be collected by the collection box on the lower side, realizing the automatic collection of the lower template 2 after feeding.
