The following embodiments are used to illustrate this utility model.
[0028] like Figure 2 , Figure 3 and Figure 5 As shown, a tablet die cleaning device includes: a frame 20, which is a U-shaped frame with the opening facing downwards. Multiple cleaning rollers 21 are rotatably connected to the top of the frame 20. A rectangular plate is also installed inside the opening of the frame 20. A motor for driving the cleaning rollers 21 to rotate is installed on one side of the bottom of the rectangular plate. Each adjacent cleaning roller 21 is connected to a belt 23 for transmission. Multiple nozzles 22 are evenly installed at the bottom of the frame 20. The motor is electrically connected to a power source. The bottom end of the nozzle 22 is connected to a water supply pipe. The structural layout of the frame 20, cleaning rollers 21 and belt 23 is consistent with the cleaning mechanism in the prior art (publication number: CN213435838U). This is prior art, so it will not be described in detail here.
[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the enclosure structure is set on the outer wall of the frame 20 to fix the punch. The enclosure structure includes an outer enclosure 30, a top frame 31, and clamping rods 34. The outer enclosure 30 is a rectangular box with an open bottom and a hollow interior. The frame 20 is fixedly connected to the cavity of the outer enclosure 30. The top frame 31 is fixedly connected to the top of the outer enclosure 30 by rectangular plates symmetrically installed at the bottom. The clamping rods 34 are symmetrically slidably connected to the wall of the top frame 31. The symmetrical clamping rods 34 can fix the punch above the cleaning roller 21.
[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the top opening of the outer enclosure 30 gradually widens, the top frame 31 is a rectangular frame, and the clamping rod 34 is a rectangular rod that can slide along the cavity of the top frame 31. The enclosure structure also includes a screw 32, a limiting rail 33, a slot 35, a threaded groove 36, and a limiting wheel 37. The screw 32 is rotatably connected to the rear of the cavity of the top frame 31, the limiting rail 33 is fixedly connected to the front wall of the top frame 31, the slot 35 is formed on the side wall of each clamping rod 34, the threaded groove 36 is formed through the side wall of the clamping rod 34, and the limiting wheel 37 is fixedly connected to the front wall of each clamping rod 34. The screw 32 is a cylindrical part with opposing threads on an arc surface, and both ends of the screw 32 can pass through the cavity of the top frame 31. The rod 32 has the same handle installed at both ends. The front wall of the top frame 31 has a rectangular groove. The limiting rail 33 is a U-shaped rod. The opening of the limiting rail 33 can communicate with the rectangular groove on the wall of the top frame 31. The screw 32 can pass through the screw groove 36 and be threaded to the wall inside the screw groove 36. The slot 35 is a slot with a semi-circular cross section. The slots 35 on the wall of the symmetrical clamping rod 34 face each other. The limiting wheel 37 is composed of two upper and lower semi-capsule-shaped blocks and a rotating wheel in the middle. The opening of the limiting rail 33 can accommodate the sliding of the limiting wheel 37. The wheel of the limiting wheel 37 can contact the wall of the opening of the limiting rail 33. The rectangular groove on the front wall of the top frame 31 can also accommodate the sliding of the limiting wheel 37.
[0031] In practical use, first, flip the cover plate 42 to one side with the adapter 41 as the center, so that the top of the outer enclosure 30 is open. Then, align the mold groove of the die to be cleaned downwards with the top of the cleaning roller 21. At this time, the die will be briefly pushed into the cavity of the top frame 31. Then, turn the handle on the wall of the screw 32. As the handle is turned, the screw 32 will rotate in the cavity of the top frame 31. When the screw 32 rotates, it will drive the symmetrical clamping rods 34 to move towards each other through the threads on its wall. When the clamping rods 34 move, they will drive the wheels of the limiting wheel 37 to roll synchronously in the opening of the limiting rail 33. After they are engaged with both sides of the die in the slot 35, you can stop turning the handle. Then, put the cover plate on the top frame 31. The plate 42 rotates and is placed above the outer enclosure 30. Then, the motor is turned on and water is sprayed out of the nozzle 22 towards the die. When the motor is turned on, it can drive the cleaning roller 21 to rotate. When the cleaning roller 21 rotates, it will drive another cleaning roller 21 to rotate through the belt 23 on its wall. In this way, the top of the rotating cleaning roller 21 can rotate and clean the inside of the mold groove, and rinse it with the water sprayed from the nozzle 22. The water used for cleaning will drip from the die wall into the cavity of the outer enclosure 30 for storage. After the die is cleaned, the top of the outer enclosure 30 is opened in the same way, and the clamping rod 34 is removed by rotating the handle to remove the clamping of the die. Then the cleaned die is removed.
[0032] In summary, by setting up an enclosure structure, the inverted die groove of the punch, combined with the outer enclosure 30 that can collect cleaning wastewater, can both reduce residual water stains on the die wall after cleaning and facilitate the recycling of cleaning wastewater.
[0033] like Figure 1 , Figure 2 and Figure 3 As shown, the outer enclosure 30 has a covering structure on its wall surface. The covering structure includes a substrate 40, a connector 41, and a cover plate 42. The substrate 40 is symmetrically fixedly connected to one side wall of the outer enclosure 30. The connector 41 is rotatably connected between the symmetrical substrates 40. The cover plate 42 is fixedly connected to the top of the connector 41. The substrate 40 is a rectangular plate with a circular groove on its front wall surface. The cover plate 42 is made of transparent acrylic. The connector 41 is composed of a rectangular plate and symmetrical cylinders on the front and rear walls. The cylinders on the wall surface of the connector 41 can rotate in the circular grooves on the corresponding substrate 40 wall surface. The cover plate 42 is a U-shaped cross-section plate with the opening facing downwards. The opening of the cover plate 42 can be adapted to the size of the top frame 31.
[0034] In practical use, when the cover plate 42 is flipped, the cover plate 42 will rotate synchronously with the adapter 41 as the center by rotating between the symmetrical substrates 40 through the adapter 41.
[0035] In summary, by setting up a covering structure, it is possible to prevent water from splashing everywhere during cleaning by covering the top of the device, and it is also possible to prevent dust from accumulating on the device when it is not in use.
[0036] Working principle: Flip the cover plate 42 to one side with the adapter 41 as the center, so that the top of the outer enclosure 30 is open. Then, align the mold groove of the die to be cleaned downwards with the top of the cleaning roller 21. At this time, the die will be briefly pushed into the cavity of the top frame 31. Then, turn the handle on the wall of the screw 32. As the handle is turned, the screw 32 will rotate in the cavity of the top frame 31. When the screw 32 rotates, it will drive the symmetrical clamping rods 34 to move towards each other through the threads on its wall. When the clamping rods 34 move, they will drive the wheels of the limiting wheel 37 to roll synchronously in the opening of the limiting rail 33. After they are engaged with the two sides of the die in the slot 35, the handle can be stopped. Then, rotate the cover plate 42 and place it on top of the outer enclosure 30. Then, the motor is turned on and water is sprayed out of the nozzle 22 towards the die. When the motor is turned on, it can drive the cleaning roller 21 to rotate. When the cleaning roller 21 rotates, it will drive another cleaning roller 21 to rotate through the belt 23 on its wall, and so on. The top of the rotating cleaning roller 21 can rotate and clean the inside of the die groove, and rinse it with the water sprayed from the nozzle 22. The water used for cleaning will drip from the die wall into the cavity of the outer enclosure 30 for storage. After the die is cleaned, the top of the outer enclosure 30 is opened in the same way, and the clamping rod 34 is removed by turning the handle. Then the cleaned die is removed and replaced with the next die to be cleaned, and then the cleaning is carried out in the same way.
