Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0053] like Figure 1 , Figure 2 As shown, a tablet crushing device for a western pharmacy includes a base plate 1, a shell 3 and a placement mechanism 2. The shell 3 is fixedly installed on the top of the base plate 1. A reciprocating mechanism 4 and a crushing mechanism 5 are arranged inside the shell 3. The crushing mechanism 5 is connected to the reciprocating mechanism 4. The base plate 1 ensures that the device is always in a stable state during operation. The shell 3 can not only protect the reciprocating mechanism 4 and the crushing mechanism 5, but also prevent the powder from splashing out when the tablets are crushed.

On the output shaft of the motor 406, the other end of the rotating rod 407 is connected to the lifting frame 402, the column 404 is fixedly installed on the top of the fixed frame 401, the middle part of the rotating arm 403 is rotatably installed on the column 404, the lifting frame 402 is connected to one end of the rotating arm 403, and the two ends of the push-pull rod 405 are respectively connected to the other end of the rotating arm 403 and the crushing mechanism 5. The placing mechanism 2 is arranged below the crushing mechanism 5 and is pulled out and installed on the shell 3.

[0055] The motor 406 is turned on to drive the rotating rod 407 to rotate. When the rotating rod 407 rotates, the fixed column 408 at the other end of the rotating rod 407 slides along the first strip hole 4016 in the middle of the lifting plate 4014. When the fixed column 408 slides along the first strip hole 4016, the lifting plate 4014 is driven to move up and down. When the lifting plate 4014 moves up and down, the sliding rod 4015 is driven to move up and down. When the sliding rod 4015 moves up and down, the fixed rod 4017 at the top of the sliding rod 4015 is driven to slide along the waist-shaped hole 4018. When the fixed rod 4017 slides in the waist-shaped hole 4018, it will drive the rotating arm 403 to rotate. One end of the rotating arm 403 moves upward under the action of the sliding rod 4015, and the other end of the rotating arm 403 moves downward. When the other end of the rotating arm 403 moves downward, it will push the push-pull rod 405 to move downward. The downward movement of the push-pull rod 405 will drive the crushing mechanism 5 to move downward. When the crushing mechanism 5 moves downward, the crushing block 502 and the tablets inside the placement groove 202 on the placement plate 201 are crushed.

[0056] As an optimization solution of the present invention, Figure 5 As shown, the fixed frame 401 includes a top plate 4010 and vertical rods 409 installed on both sides of the top plate 4010, and the inner wall of the vertical rod 409 is provided with a sliding groove 4012 and a sliding hole 4013, and the sliding groove 4012 and the sliding hole 4013 are arranged one above and one below, the sliding groove 4012 is slidably matched with the lifting frame 402, and the sliding hole 4013 is slidably matched with the crushing mechanism 5.

[0059] The setting of the lifting plate 4014 can cooperate with the rotating arm 403 to ensure that the lifting plate 4014 reciprocates while pulling the push-pull rod 405 to reciprocate, thereby driving the crushing mechanism 5 to reciprocate and crush the tablets in the placing mechanism 2, thereby greatly improving the efficiency and quality of tablet crushing.

[0060] As an optimization solution of the present invention, Figure 6 As shown, a first strip hole 4016 is opened on the lifting plate 4014. Figure 4As shown, a fixing column 408 is fixedly installed on the other end of the rotating rod 407 , and the fixing column 408 is disposed in the first bar-shaped hole 4016 , and the fixing column 408 is slidably matched with the first bar-shaped hole 4016 .

[0061] The provision of the fixing column 408 and the first strip hole 4016 ensures the normal operation of the rotating rod 407 and can ensure the normal up and down reciprocating motion of the lifting plate 4014 .

When the rotating rod 407 rotates around the output shaft of the motor 406, it will drive the crushing mechanism to move up and down reciprocatingly, thereby achieving the purpose of reciprocatingly crushing the tablets.

[0078] Example 2

[0079] In order to prevent the crushed tablets from sticking to the bottom of the placement groove 202, the reset mechanism 6 and the scraper 203 are set to scrape off the powder stuck to the bottom of the placement groove 202 to prevent the powder from sticking to the bottom of the placement groove 202 and reducing the dosage of the powder. When the crushing block 502 rises upward, the compressed spring 6010 resets and drives the limit rod 601 and the pulling plate 605 to reset. When the limit rod 601 rotates around one end, the sliding column 604 on the other end of the limit rod 601 slides along the third strip hole 602. When the sliding column 604 moves to the end of the third strip hole 602, the spring 6010 continues to reset and drives the sliding block 609 and the limit column 6012 to move along the support rod 6011. While moving, the limit column 6012 will move along the edge of the limit rod 601. The movable side rod 208 moves, and the movement of the side rod 208 will drive the scraper plate 205 to move along the guide rod 206 to the middle of the placement groove 202. When the scraper plate 205 moves, the powder stuck to the bottom of the placement groove 202 can be scraped off. When the crushing block 502 descends again, it will push the scraper plate 205 to both sides. When the scraper plate 205 moves to both sides, it will drive the limiting column 6012 to move along the limiting rod 601, and when the limiting column 6012 moves, it will drive the sliding block 609 to move along the support rod 6011. When the sliding block 609 moves, the spring 6010 will be compressed. Such reciprocating movement can not only improve the crushing quality of the tablets, but also prevent the powder from sticking to the bottom of the placement groove 202 and affecting the dosage of the powder, thereby greatly ensuring the crushing efficiency and crushing quality of the tablets by the device.
