In this configuration, it is further ensured that the grinding assembly 204 can move upward.

[0043] like Figures 2 to 4 and Figure 7 As shown, further, a driving plate 301 is disposed above each of the four grinding assemblies 204, and the four driving plates 301 are symmetrical to each other. Two symmetrical second telescopic rods 3011 are disposed on opposite side walls of each of the four driving plates 301, and one end of each second telescopic rod 3011 away from the driving plate 301 is disposed on the inner wall of the placement slot 1014.

In this arrangement, it is ensured that the cleaning plate 303 can be driven to move when the driving rod 3022 moves.

[0047] The implementation principle of the device for cutting off the edge material of a blister tray in this embodiment is as follows:

[0048] First, the staff places the blister tray body 105 on the placement plate 2017 set in the inner cavity of the placement slot 1014 opened on the workbench 101. When the placement is completed, the staff controls the hydraulic cylinder 102 to operate through the controller, so that the hydraulic cylinder 102 can drive the cutting knife 1021 to move vertically downward, thereby cutting the placed blister tray body 105. When the cutting is completed, the staff controls the hydraulic cylinder 102 to reset through the controller so that the cutting knife 1021 can be reset, and then the staff controls the servo motor 201 to operate through the controller;

[0049] When the servo motor 201 is running, the servo motor 201 can drive the threaded rod 2011 to rotate. When the threaded rod 2011 rotates, it can drive the threaded sleeve 2013 to move vertically upward with the assistance of the slider 2014 and the slide groove 1031. When the threaded sleeve 2013 moves vertically upward, it can drive the placement plate 2017 to move vertically upward through the connecting rod 2016. When the placement plate 2017 moves vertically upward, it can drive the cut blister tray body 105 to move vertically upward.

[0050] At the same time, when the slider 2014 moves vertically upward, the slider 2014 will be able to drive the moving block 2015 to move vertically upward on the moving notch 1032. When the moving block 2015 moves vertically upward, it can drive the circular fixed cylinder 202, the circular plug rod 2021 and the fixed plate 2024 to move vertically upward. Because the fixed plate 2024 is fixedly connected with the Z-shaped rod 2033 on the top, and the Z-shaped rod 2033 is connected to the moving slide bar 2032, the slide bar 2032 can be moved on the special-shaped slide groove 2031, so that the fixed plate 2024 can be moved horizontally while rising;

[0051] When the fixed plate 2024 moves vertically upward and horizontally, it can drive the grinding assembly 204 to move horizontally through the special-shaped rod 2034, so that the grinding assembly 204 can approach the blister tray body 105 and move upward until the grinding assembly 204 and the blister tray body 105 are in contact. At this time, the staff can control the grinding assembly 204 to operate through the controller, so that the Shudie grinding assembly 204 can grind the side wall of the blister tray body 105;

[0052] When the grinding assembly 204 rises to a certain position, the slide bar 2032 can move upward and away from the blister tray body 105 with the assistance of the special-shaped slide groove 2031, so that the grinding assembly 204 can squeeze the driving plate 301 to move with the assistance of the second telescopic rod 3011, so that the driving plate 301 can squeeze the airbag 3013, so that one side of the airbag 3013 located in the fixed cylinder 3012 can swell, thereby pushing the driving rod 3022 to move horizontally. When the driving rod 3022 moves horizontally, When the blister tray body 105 is moved, the cleaning plate 303 can be driven to move, so that the cleaning plate 303 can be close to the blister tray body 105. Because the blister tray body 105 is always in a state of vertical upward movement, the side wall of the polished blister tray body 105 can be cleaned by the cleaning plate 303, thereby avoiding the situation where debris and the like are adsorbed on it. When the blister tray body 105 leaves the cleaning plate 303, the staff controls the servo motor 201 to stop running through the controller, so that the cut blister tray body 105 can be taken out.
