Description

Technical Field

[0001] This utility model relates to the field of one-piece plastic cap processing technology, and in particular to a cap-closing device for processing high-temperature resistant one-piece plastic caps. Background Technology

[0002] Integrated plastic caps refer to cap assemblies formed by connecting multiple individual caps together during manufacturing using plastic connecting ribs. This design maintains its integrity during transportation and filling, facilitating efficient and continuous cap picking, screwing, or pressing on in automated production lines, significantly improving sealing speed and stability. They are primarily used in high-speed filling applications such as beverages and dairy products. However, the production of high-temperature resistant integrated plastic caps requires specialized cap-making equipment.

[0003] Existing devices lack automatic unlocking functionality due to their fixed structures. In some small factories, manual intervention is required to remove the cap after it has been closed, which not only increases processing time but may also cause damage or secondary contamination to the cap due to improper handling, affecting production continuity and product quality. Furthermore, traditional connection methods may require special tools or complex operations to install and disassemble the clamping mechanism. When it is necessary to replace the clamping mechanism with different specifications to accommodate different sizes of one-piece plastic caps, the operation is cumbersome and time-consuming, reducing the equipment's versatility and production efficiency. Therefore, a cap-closing device for processing high-temperature resistant one-piece plastic caps is proposed to solve the above problems. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides a cap-closing device for processing high-temperature resistant one-piece plastic caps, aiming to improve the problems of manual cap removal and cumbersome disassembly and assembly of clamping mechanisms in the prior art after cap closure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a lid-closing device for processing high-temperature resistant one-piece plastic lids, comprising a machine body, a turntable provided on the inner wall of the machine body, a clamping mechanism provided on the inner wall of the turntable, a fixing mechanism provided on the inner wall of the turntable, a lid-closing device fixedly connected to the inner wall of the machine body, and a fixing ring provided on the inner wall of the machine body. The clamping mechanism includes a connecting block detachably connected to the inner wall of the turntable. A fixing sleeve is fixedly connected to the top outer wall of the connecting block. A first sliding rod is slidably connected to the inner wall of the fixing sleeve. The first sliding rod is elastically connected to the inner wall of the fixing sleeve by a first spring. A sliding block is fixedly connected to the outer wall of the first sliding rod. A conical block is fixedly connected to the bottom outer wall of the sliding block. A connecting sleeve is fixedly connected to the side wall of the first sliding rod. A clamp is slidably connected to the inner wall of the connecting sleeve. A bolt is threadedly connected to the inner wall of the connecting sleeve. A placement plate is hinged to the inner wall of the fixing sleeve. A first inclined block is fixedly connected to the bottom outer wall of the placement plate.

[0006] As a further description of the above technical solution: the fixing mechanism includes a second sliding rod, which is slidably connected to the inner wall of the turntable. The second sliding rod is elastically connected to the inner wall of the turntable by a second spring. A fixing plate is fixedly connected to the outer wall of the second sliding rod, and a second inclined block is fixedly connected to the side wall of the second sliding rod. A threaded rod is threadedly connected to the inner wall of the turntable.

[0007] As a further description of the above technical solution: the sliding block is slidably connected to the inner wall of the fixed sleeve, and the bolt is in contact with the connecting rod of the clamp.

[0008] As a further description of the above technical solution: the top outer wall of the fixing ring is provided with a first groove, the bottom outer wall of the first inclined block is in contact with the first groove, and the turntable is rotatably connected to the inner wall of the fixing ring.

[0009] As a further description of the above technical solution: a second groove is provided on the bottom side wall of the placement plate, and the conical block is in contact with the second groove.

[0010] As a further description of the above technical solution: the threaded rod is in contact with the inclined surface of the second inclined block.

[0011] As a further description of the above technical solution: the outer wall of the connecting block is provided with a slot, and the second sliding rod is engaged in the slot.

[0012] As a further description of the above technical solution: one end of the second spring is fixedly connected to the outer wall of the fixed plate, and the other end of the second spring is fixedly connected to the inner wall of the turntable.

[0013] This utility model has the following beneficial effects: 1. In this utility model, after the turntable rotates and the cover is closed by the cover-closing device, when it rotates to the first groove, the first inclined block moves down accordingly. The conical block is squeezed out of the second groove and is retracted into the fixed sleeve. When the conical block moves, it drives the sliding block, which in turn drives the first sliding rod and stretches the first spring. When the first sliding rod moves, it drives the clamp on the connecting sleeve to retract into the fixed sleeve, releasing the fixation of the integrated cover. This allows the integrated cover to be automatically retracted along the downward-moving placement plate after closing, thereby improving the problem of needing to manually remove the cover after closing in the prior art.

[0014] 2. In this utility model, the connecting block is placed on the turntable, and then the threaded rod is rotated to press the second inclined block, so that the second sliding rod slides and stretches the second spring until the second sliding rod engages with the slot on the connecting rod, thus completing the fixation of all clamping mechanisms, thereby improving the problem of cumbersome disassembly and assembly of clamping mechanisms in the prior art.

The clamping mechanism 2 is used to fix the one-piece lid and automatically unlocks after closing to achieve automatic recycling. A fixing mechanism 3 is provided on the inner wall of the turntable 5. The fixing mechanism 3 facilitates quick disassembly and assembly of the clamping mechanism 2 to adapt to one-piece lids of different specifications. A lid-closing device 4 is fixedly connected to the inner wall of the machine body 1. The lid-closing device 4 completes the lid-closing processing operation of the one-piece plastic lid. A fixing ring 6 is provided on the inner wall of the machine body 1. A first groove 212 is opened on the outer wall of the top of the fixing ring 6. The fixing ring 6 allows the turntable 5 to rotate. Its first groove 212 cooperates with the first inclined block 22 to assist the placement plate 23 in resetting.

[0019] Reference Figures 2-4As shown, the clamping mechanism 2 includes a connecting block 31. A slot 32 is provided on the outer wall of the connecting block 31. The connecting block 31 connects the turntable 5 and the fixing sleeve 21 to support the clamping mechanism 2. The connecting block 31 is detachably connected to the inner wall of the turntable 5. A fixing sleeve 21 is fixedly connected to the top outer wall of the connecting block 31. The fixing sleeve 21 can fix the components of the clamping mechanism 2 to ensure stable operation. A first sliding rod 29 is slidably connected to the inner wall of the fixing sleeve 21. The first sliding rod 29 can transmit force to drive the connecting sleeve 25 and the clamp 24 to move. 29 is elastically connected to the inner wall of the fixed sleeve 21 by the first spring 27. The first spring 27 can reset the first sliding rod 29 and the connecting sleeve 25 to the clamp 24. A sliding block 28 is fixedly connected to the outer wall of the first sliding rod 29. The sliding block 28 is slidably connected to the inner wall of the fixed sleeve 21. The sliding block 28 moves with the first sliding rod 29, causing the conical block 210 to move. The conical block 210 is fixedly connected to the outer wall of the bottom end of the sliding block 28. The conical block 210 contacts the second groove 211. The upper and lower ends of the conical block 210 are inclined surfaces when placed. When plate 23 falls or rises, it can squeeze the inclined plane to retract the conical block 210 into the fixed sleeve 21. A connecting sleeve 25 is fixedly connected to the side wall of the first sliding rod 29. The connecting sleeve 25 connects the first sliding rod 29 to the clamp 24 to adjust the position of the clamp 24. The clamp 24 is slidably connected to the inner wall of the connecting sleeve 25. The clamp 24 can directly clamp the cover to prevent displacement during processing. A bolt 26 is threadedly connected to the inner wall of the connecting sleeve 25. The bolt 26 contacts the connecting rod of the clamp 24. The bolt 26 fixes the connecting rod of the clamp 24 and adjusts the clamping of the clamp 24. Within the scope, a placement plate 23 is hinged to the inner wall of the fixed sleeve 21. A second groove 211 is provided on the bottom side wall of the placement plate 23. The placement plate 23 places the cover to be processed and provides a platform for closing the cover. A first inclined block 22 is fixedly connected to the bottom outer wall of the placement plate 23. The bottom outer wall of the first inclined block 22 contacts the first groove 212. The first inclined block 22 is a counterweight. When the turntable 5 rotates to the first groove 212, the placement plate 23 can rotate and adjust the angle to drop the integrated cover behind the box cover. Then, the inclined block drives the placement plate 23 to return to its original position.

[0020] Reference Figure 5As shown, the fixing mechanism 3 includes a second sliding rod 33, which is engaged in a slot 32. The second sliding rod 33 is engaged in the slot 32 and fixed to the connecting block 31 under the control of a second spring 35. The second sliding rod 33 is slidably connected to the inner wall of the turntable 5. The second sliding rod 33 is elastically connected to the inner wall of the turntable 5 through the second spring 35. One end of the second spring 35 is fixedly connected to the outer wall of the fixing plate 34, and the other end of the second spring 35 is fixedly connected to the inner wall of the turntable 5. The second spring 35 can provide elastic force to make the second sliding rod... 33 resets and clamps the slot 32. A fixing plate 34 is fixedly connected to the outer wall of the second sliding rod 33. The fixing plate 34 fixes one end of the second spring 35 and transmits the elastic force of the second spring 35. A second inclined block 36 is fixedly connected to the side wall of the second sliding rod 33. The second inclined block 36 is squeezed by the threaded rod 37 and drives the second sliding rod 33 to move. A threaded rod 37 is threadedly connected to the inner wall of the turntable 5. The threaded rod 37 contacts the inclined surface of the second inclined block 36. The threaded rod 37 rotates and squeezes the second inclined block 36 to control the action of the second sliding rod 33.

[0021] In use, the unclosed connecting cover is placed on the placement plate 23 and fixed by the clamp 24. After the turntable 5 is rotated, the cover is closed by the closing device 4. When the turntable rotates to the first groove 212, the first inclined block 22 moves down. The conical block 210 is squeezed out of the second groove 211 and retracts into the fixed sleeve 21. When the conical block 210 moves, it drives the sliding block 28, which in turn drives the first sliding rod 29 and stretches the first spring 27. When the first sliding rod 29 moves, it drives the clamp 24 on the connecting sleeve 25 to retract into the fixed sleeve 21, releasing the fixation of the connecting cover. The closed connecting cover is then automatically retracted along the lowered placement plate 23. Afterward, the first inclined block 22 resets and the first spring 27 resets the components to their original positions.

[0022] When the clamping mechanism 2 needs to be installed, place the connecting block 31 into the turntable 5, rotate the threaded rod 37 to press the second inclined block 36, drive the second sliding rod 33 to slide and stretch the second spring 35 through the fixing plate 34 until the second sliding rod 33 is inserted into the slot 32 of the connecting block 31 to complete the fixing; when disassembling, rotate the threaded rod 37 in the opposite direction, the second spring 35 resets and pulls the second sliding rod 33 out of the slot 32, and the connecting block 31 can be removed.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
