Description

Technical Field

[0001] This utility model relates to the field of plastic cap production technology, and in particular to a device for removing burrs during plastic cap production. Background Technology

[0002] Plastic caps are a common packaging form for bottles, cans, and barrels, especially in the beverage, chemical, and pharmaceutical industries. They can be divided into breathable plastic caps and non-breathable plastic caps according to their uses. During the production of plastic caps, a flash removal device is required to remove the flash from the plastic caps.

[0003] For example, application number CN210758436U discloses "a device for removing burrs in the production of plastic caps," which specifically discloses that: a drive motor is installed on the upper right side of the base, and a rotating shaft is fixed to the left side of the drive motor. A bracket is installed on the left side of the rotating shaft, and cutting blades are fixed on both the upper and lower sides of the bracket. A hydraulic cylinder is installed on the upper left side of the base, and a hydraulic rod is fixed to the right side of the hydraulic cylinder. A base is fixed to the right side of the hydraulic rod, and springs are fixed to both the upper and lower sides of the base. A movable plate is fixed to the outside of the springs. An outer frame is set outside the hydraulic rod, and a fixing block is fixed to the right side of the outer frame. A pull box is set below the outer frame. The plastic cap is square, and the bottom of the pull box is installed in conjunction with the slide groove, which is located on the left side of the upper surface of the base. The pull box has a pull plate inside, and both sides of the pull plate are installed in conjunction with the slide rails, which are located on both sides of the inner wall of the pull box. However, in the above-mentioned technology, the plastic cap is only clamped and fixed by a spring during use. This makes it easy for the cutting blade to move the plastic cap when the plastic cap is being processed, causing the blade to cut other parts of the plastic cap, resulting in poor processing effect and reducing the practicality of the device. Therefore, this utility model proposes a plastic cap flash removal device to solve the above problems. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a flash removal device for plastic cap production. This solves the problem in the prior art where only springs are used to clamp and fix the plastic cap, which makes it easy for the cutting blade to move the plastic cap during flash removal, causing the blade to cut other parts of the plastic cap and resulting in poor processing quality.

[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a flash removal device for producing plastic caps, including a base plate, an mounting frame installed on one side of the top of the base plate, a first servo motor installed at the bottom of the mounting frame, a placement plate installed on the lower inner side of the mounting frame, the output end of the first servo motor connected to one end of the placement plate, a positioning mechanism provided above the placement plate, a side plate installed on the other side of the top of the base plate, a placement plate installed on the upper inner side of the side plate, and a moving mechanism provided on the upper outer side of the side plate;

[0006] The positioning mechanism includes a cylinder, a mounting plate, a rotating plate, a fixed groove, and a movable block. The cylinder is mounted on the top of the mounting frame, and the output end of the cylinder extends to the inside of the mounting frame. The output end of the cylinder is mounted on the mounting plate, and the mounting plate has a fixed groove inside. The fixed groove has a movable block inside, and the bottom end of the movable block is mounted on the rotating plate.

[0007] A further improvement is that two movable blocks are arranged inside the fixed groove, and the two movable blocks are symmetrically distributed inside the fixed groove.

[0008] A further improvement is that the fixing groove is circular inside the mounting plate, and the center of the fixing groove is on the same straight line as the center of the placement plate.

[0009] A further improvement is made in that: the moving mechanism includes a mounting cavity, a second servo motor, a threaded rod, a threaded sleeve, a moving cavity, and a limiting structure. The mounting cavity is mounted on the upper side of one side of the side plate. The second servo motor is mounted on one end of the mounting cavity. The threaded rod is mounted inside the mounting cavity. The output end of the second servo motor is connected to one end of the threaded rod. A threaded sleeve is provided on the outer wall of the threaded rod. The moving cavity is fixedly mounted on the outer wall of the threaded sleeve. One end of the moving cavity extends to the inner side of the side plate. One end of the moving cavity is connected to one side of the grinding assembly.

[0010] A further improvement is that the limiting structure includes a limiting groove and a limiting block. The limiting groove is opened on both sides inside the mounting cavity, and the limiting block is provided inside the limiting groove. One end of the limiting block is connected to the outside of the moving cavity.

[0011] A further improvement is that the cross-section of the limiting groove is larger than the cross-section of the limiting block, and the limiting groove and the limiting block form a sliding structure.

[0012] The beneficial effects of this utility model are as follows: By setting a positioning mechanism above the placement plate, the rotation plate can be driven to move downwards by the cooperation between the cylinder, mounting plate, rotating plate, fixed groove and movable block of the positioning mechanism. The plastic cover can be positioned by the cooperation between the placement plate and the rotating plate, making the plastic cover more stable and less prone to shaking during the flash treatment, thus improving the flash treatment effect of the plastic cover and greatly improving the practicality of the device in use. By setting a moving mechanism on one side of the side plate, the grinding component can be driven to move by the cooperation between the mounting cavity, second servo motor, threaded rod, threaded sleeve, moving cavity, limiting groove and limiting block of the moving mechanism, making the grinding component more convenient and faster when performing flash treatment on the plastic cover, thus greatly improving the convenience of the device in use.

[0019] The positioning mechanism includes a cylinder 7, a mounting plate 8, a rotating plate 9, a fixing groove 10, and a movable block 11. The cylinder 7 is mounted on the top of the mounting frame 2, and its output end extends to the inner side of the mounting frame 2. The mounting plate 8 is mounted on the output end of the cylinder 7. The fixing groove 10 is formed inside the mounting plate 8, and the movable block 11 is arranged inside the fixing groove 10. The rotating plate 9 is mounted on the bottom end of the movable block 11. Two movable blocks 11 are arranged inside the fixing groove 10, and the two movable blocks 11 are symmetrically arranged inside the fixing groove 10. The fixing groove 10 is circular inside the mounting plate 8, and the center of the fixing groove 10 is on the same straight line as the center of the placement plate 4. In use, the plastic cover is placed on the placement plate 4, and then the cylinder 7 is activated to drive the mounting plate 8 and the rotating plate 9 to move downwards, so that the rotating plate 9 comes into contact with the inner side of the plastic cover. The placement plate 4 and the rotating plate 9 are used to position the plastic cover, making the plastic cover more stable and less prone to shaking during the edge treatment. Therefore, the edge treatment effect of the plastic cover is better, which greatly improves the practicality of the device in use.

[0020] The moving mechanism includes a mounting cavity 12, a second servo motor 13, a threaded rod 14, a threaded sleeve 15, a moving cavity 16, and a limiting structure. The mounting cavity 12 is mounted on the upper side of one side of the side plate 5. The second servo motor 13 is mounted on one end of the mounting cavity 12. The threaded rod 14 is mounted inside the mounting cavity 12. The output end of the second servo motor 13 is connected to one end of the threaded rod 14. A threaded sleeve 15 is provided on the outer wall of the threaded rod 14. The moving cavity 16 is fixedly mounted on the outer wall of the threaded sleeve 15. One end of the moving cavity 16 extends into the inner side of the side plate 5. On one side, one end of the moving cavity 16 is connected to one side of the grinding assembly 6. In use, the second servo motor 13 is started to drive the threaded rod 14 to rotate, which in turn drives the threaded sleeve 15 to move. Under the limitation of the limiting groove 17 and the limiting block 18, the threaded sleeve 15 drives the moving cavity 16 to move, which in turn drives the grinding assembly 6 to move. The grinding assembly 6 is adjusted to an appropriate position so that the grinding assembly 6 contacts the edge of the bottle cap, making it more convenient and faster to process the plastic cap with burrs, thereby greatly improving the convenience of the device in use.

The cross-section of the limiting groove 17 is larger than the cross-section of the limiting block 18. The limiting groove 17 and the limiting block 18 form a sliding structure. In use, the mutual cooperation between the limiting groove 17 and the limiting block 18 can limit the movement of the moving cavity 16, making the moving cavity 16 more stable during movement.

[0022] Working principle: The operator first places the plastic cap on the placement plate 4, then starts the cylinder 7 to move the mounting plate 8 and the rotating plate 9 downwards, so that the rotating plate 9 comes into contact with the inside of the plastic cap. The placement plate 4 and the rotating plate 9 are used to position the plastic cap. Then, the second servo motor 13 is started to rotate the threaded rod 14, which moves the threaded sleeve 15. Under the limitation of the limiting groove 17 and the limiting block 18, the threaded sleeve 15 moves the moving cavity 16, which in turn moves the grinding component 6. The grinding component 6 is adjusted to a suitable position so that it comes into contact with the edge of the bottle cap. At this time, the grinding component 6 is started to remove the burrs from the plastic cap. Then, the first servo motor 3 is started to rotate the placement plate 4. With the cooperation of the fixed groove 10 and the movable block 11, the plastic cap rotates, and the burrs are removed from the plastic cap more thoroughly.
