Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figures 1 to 4 As shown, the utility model provides an anti-sticking tablet press, including a base plate 1, a frame 2, a collecting box 3, a mounting plate 4, a cylinder 5, an upper template 6 and a lower template 7.

A movable plate 8 is provided on the front side of the frame 2, and the rear side of the movable plate 8 is fitted with the front side of the frame 2. A scraper 9 is fixedly connected to the front side of the movable plate 8, and a scraping mechanism 10 is fixedly connected to the left and right sides of the upper template 6. A transmission assembly 11 is provided on the rear side of the frame 2.

[0025] refer to Figure 1 The scraping mechanism 10 includes a second ear 101, and the left and right sides of the frame 2 are fixedly connected to the first ear 102. A limiting frame 103 is arranged on the rear side of the frame 2. The end of the limiting frame 103 close to the upper template 6 passes through the first ear 102 and the second ear 101 in sequence and extends to the front side of the second ear 101. The limiting frame 103 is movably connected to the first ear 102 and the second ear 101.

[0026] As a technical optimization solution of the utility model, by setting the scraping mechanism 10, the first ear 102 can limit the limit frame 103 up, down, left and right, and the limit frame 103 can position the second ear 101 and the upper template 6. The positioned upper template 6 is located directly in front of the scraper 9, so that the scraper 9 can accurately scrape off the residual powder at the bottom of the upper template 6 when it moves to the front side.

[0027] refer to Figure 3 The transmission assembly 11 includes a fixed frame 111, an electric push rod 112 and a through hole 113. The through hole 113 is opened on the rear side of the frame 2. The two sides of the inner wall of the fixed frame 111 are fixedly connected to the left and right sides of the frame 2. The electric push rod 112 is fixedly installed on the rear side of the inner wall of the fixed frame 111, and the output end of the electric push rod 112 is fixedly connected to the rear side of the movable plate 8.

[0028] As a technical optimization solution of the utility model, by setting up the transmission component 11, the through hole 113 is used to provide a moving path for the electric push rod 112, and the fixed frame 111 can fix and limit the electric push rod 112. By starting the electric push rod 112, the output end of the electric push rod 112 can drive the moving plate 8 and the scraper 9 to move toward the front side.

[0029] refer to Figure 3 The left and right sides of the fixed frame 111 are fixedly connected with a support plate 12, the front side of the support plate 12 is fixedly connected with a telescopic rod 13, and the other end of the telescopic rod 13 is fixedly connected to the left and right sides of the rear side of the movable plate 8.

[0030] As a technical optimization solution of the utility model, by setting the support plate 12 and the telescopic rod 13, the support plate 12 can fix and limit the telescopic rod 13, and the forward and backward movement of the movable plate 8 can drive the telescopic rod 13 to extend and retract. At this time, the telescopic rod 13 can guide the movable plate 8, thereby improving the stability of the movement of the movable plate 8.

[0031] refer to Figure 4 A fixing groove 14 is provided on the front side of the scraper 9, a magnetic block 15 is fixedly connected to the inner wall of the fixing groove 14, and a collecting frame 16 is magnetically connected to the front side of the magnetic block 15. The collecting frame 16 is made of iron and is L-shaped.

[0032] As a technical optimization solution of the utility model, by setting a fixed groove 14, a magnetic block 15 and a collecting rack 16, the fixed groove 14 can fix and limit the magnetic block 15, and the magnetic block 15 can limit the collecting rack 16. The collecting rack 16 is used to collect the powder dropped by the scraper 9. At the same time, the magnet is used to facilitate the user to disassemble the collecting rack 16.

[0033] refer to Figure 4 A connecting groove 17 is provided on the top of the scraper 9, and the inner wall of the connecting groove 17 is filled with a cleaning pad 18, and the material of the cleaning pad 18 is sponge.

[0034] As a technical optimization solution of the utility model, by setting a connecting groove 17 and a cleaning pad 18, the connecting groove 17 can fix the cleaning pad 18, and the cleaning pad 18 made of sponge material can wipe the bottom of the lower template 7 after being cleaned by the scraper 9, thereby improving the cleaning effect.

[0035] refer to Figure 2 The left and right sides of the top of the bottom plate 1 are fixedly connected with rubber blocks 19 , and the rubber block 19 is located directly below the second ear 101 . The surface of the limiting frame 103 is fixedly connected with a limiting ring 20 .

[0036] As a technical optimization solution of the utility model, by setting a rubber block 19 and a limiting ring 20, the height of the rubber block 19 is set slightly higher than the lower template 7. When the upper template 6 descends to be pressed with the lower template 7, the rubber block 19 can reduce the pressure generated when the upper template 6 descends, thereby making the pressing of the medicine powder more stable, and the limiting ring 20 can prevent the limiting frame 103 from detaching from the first ear 102.

[0037] The working principle and use process of the utility model are as follows: when in use, first fill the lower template 7 with the medicine powder raw material, then start the cylinder 5 so that the piston end of the cylinder 5 drives the upper template 6 to descend and press it with the lower template 7. At this time, the rubber block 19 can reduce the pressure generated when the upper template 6 descends, so that the medicine powder pressing can be more stable. After the medicine powder raw material is pressed into tablets, the cylinder 5 is controlled to drive the upper template 6 to rise back to its original position. When the bottom of the upper template 6 needs to be cleaned, the limit frame 103 is first pushed forward to move the limit frame 103. One end of the rack 103 close to the upper template 6 slides into the interior of the second support ear 101, so that the upper template 6 can be positioned. Then, by starting the electric push rod 112, the output end of the electric push rod 112 drives the movable plate 8 and the scraper 9 to move forward, so that the residual powder at the bottom of the upper template 6 can be scraped off, and the scraped powder will fall into the interior of the collecting rack 16. The user can separate the collecting rack 16 from the scraper 9 by pulling the collecting rack 16, so that the user can pour the residual powder into the interior of the collecting box 3 for subsequent processing.

[0038] In summary: this anti-sticking tablet press, by setting a movable plate 8 and a scraper 9, can drive the scraper 9 to move forward by pushing the movable plate 8 to move forward to scrape off the residual powder at the bottom of the upper template 6, thereby solving the problem that the raw materials of traditional tablets are usually sticky. When the upper template presses down the powder filled in the lower template, some powder will stick to the bottom of the upper template. If it is not cleaned in time, it is easy to cause the raw materials to mix during the secondary tableting, affecting the purity of the finished tablets.
