Technical Field
[0001] This utility model relates to the field of easy-open cap technology, specifically a roll mechanism for a ring pull type easy-open beverage cap. Background Technology
[0002] As a core component of modern beverage packaging, easy-open caps directly impact consumer experience and industry development through their design and technological iterations. Currently, mainstream designs fall into two categories: pull-tab caps (RPT) and retain-on-top caps (SOT). RPTs open by tearing the cap with a pull tab and are widely used in carbonated beverages (such as Coca-Cola cans), while SOTs employ a press-type structure, retaining the complete cap to reduce waste. In the production of easy-open caps, raw materials need to be rolled and conveyed to pressing equipment for molding. This conveying process requires the use of a rolling mechanism.
[0003] However, existing pull-tab beverage easy-open cap winding mechanisms have the following problems during use: After the roll is placed on the expansion and contraction drum, the adjusting pin inside the drum needs to be manually rotated to secure it, which is cumbersome. Furthermore, after a single roll is conveyed, a new roll cannot be quickly placed in time, leading to inconvenience and affecting the efficiency of roll processing. Therefore, a corresponding technical solution needs to be designed to address these problems. Utility Model Content
[0004] The purpose of this utility model is to provide a ring pull type easy-open beverage roll mechanism, which solves the technical problems of the need to manually rotate the adjusting column in the expansion and contraction drum to fix the roll after it is placed on the expansion and contraction drum. This fixation is cumbersome, and the inconvenience caused by the inability to quickly place new rolls after a single roll is delivered is also a problem that affects the efficiency of roll processing. This invention meets the actual use needs.
[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes two supporting slide rails, an expanding and contracting drum, and a fixed side frame. A fixed housing is mounted on the supporting slide rails. Two sets of hydraulic cylinders (first type) are symmetrically arranged inside the fixed housing. A lifting top plate is mounted on the top of each hydraulic cylinder (first type). A fixed side plate is mounted on the middle side of the top of the lifting top plate.

[0008] In a preferred embodiment of this utility model, the lifting top plate is located on the top of the fixed box. The fixed box is equipped with a control module that works with the hydraulic cylinder one and the hydraulic cylinder two. The rotating sleeve is connected to the drive box by a quick-release structure. The rotating sleeve and the adjusting rod are on the same horizontal line.
[0009] In a preferred embodiment of this utility model, the driving end of the hydraulic column 2 moves through the lifting top plate, the top of the receiving plate has a concave arc structure in the middle and an inclined structure at both ends, and one end of the connecting block has a round hole and is slidably connected to the fixed slide rod.
[0010] In a preferred embodiment of this utility model, a number of fixing holes are evenly arranged in the middle of the receiving plate, and a limit side post is inserted into the fixing hole. A switch control box is integrated on one side of the fixing side plate.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] By using components such as a fixed housing and a rotating sleeve, the adjusting rod in the expanding and contracting roll can be easily rotated.

Its installation and control methods can adopt automated control. The specific setting method is a technical method commonly used in related technical fields and will not be described in detail here. The drive end of the drive box 18... A rotating sleeve 17 is inserted. Specifically, the drive box 18 is flush with the side of the fixed side plate 9 facing the expanding and contracting drum 6. When the drum is moved, the rotating sleeve 17 is not connected to the drive box 18. After the drum is placed, the rotating sleeve 17 is inserted into the drive box 18. Two hydraulic columns 12 are symmetrically arranged near the middle inside the fixed box 1. A receiving plate 8 is provided on the top of the hydraulic columns 12. Several fixed insertion holes 21 are evenly arranged in the middle of the receiving plate 8. Limiting side columns are inserted into the fixed insertion holes 21. A switch control box is integrated on one side of the fixed side plate 9. Two connecting blocks 20 are symmetrically arranged on one side of the receiving plate 8. Two fixed grooves 16 are symmetrically installed on one side of the fixed side plate 9. A fixed slide rod 19 is provided in the middle of the fixed groove 16.
[0019] Further improvements include a support slide rail 2 fixed to the bottom of a fixed side frame 3, a control box 4 installed on the side of the fixed side frame 3, an adjusting rod 7 integrated in the middle of the expansion and contraction drum 6, the end of the adjusting rod 7 having a square structure and being inserted into a rotating sleeve 17, the rotating sleeve 17 and the adjusting rod 7 being on the same horizontal line, and a limit plate 5 installed on the end of the expansion and contraction drum 6 connected to the fixed side frame 3.
[0020] Further improvements include the installation of several pulleys 13 on the bottom of the fixed housing 1, with the pulleys 13 positioned on top of the supporting slide rail 2, and the bottom ends of the fixed housing 1 being integrally connected to limit side blocks 14, which are in an "L" shape.
[0021] Further improvements include the lifting top plate 10 located on the top of the fixed housing 1, with a control module 11 installed inside the fixed housing 1 to work with the hydraulic cylinder 15 and the hydraulic cylinder 12. The rotating sleeve 17 is connected to the drive box 8 by a quick-release structure. Specifically, the quick-release structure can be a common structure in the relevant technical field, such as the quick-release structure on an electric screwdriver or an electric drill, which will not be described in detail here.
[0022] Further improvements include the fact that the driving end of the hydraulic column 12 moves through the lifting top plate 10, the top of the receiving plate 8 has a concave arc structure in the middle and an inclined structure at both ends. Specifically, the top structure of the receiving plate 8 facilitates simple fixing of the coiled material and prevents it from rolling to both sides. One end of the connecting block 20 has a round hole and is slidably connected to the fixed slide rod 19. Specifically, the connecting block 20 is slidably connected to the fixed slide rod 19, which can serve to support the receiving plate 8.
[0023] In use: When conveying rolled materials, the rolled material is placed on the receiving plate 8 and moved on the support rail 2 by the pulley 13 at the bottom of the fixed box 1, and gradually moved to the expansion and contraction drum 6. Then, according to the height, the receiving plate 8 is lifted upward by the hydraulic column 2 13, and the middle position of the rolled material is aligned with the expansion and contraction drum 6. The rolled material can then be gradually moved manually onto the expansion and contraction drum 6. After completion, the rotating sleeve 17 is installed and connected to the drive box 18, and the rotating sleeve 17 is inserted into the adjusting column 7. At this time, the drive box 18 is turned on, and the adjusting column 7 is rotated, which can gradually unfold the expansion and contraction drum 6 and fix the rolled material to the column without manual rotation.
[0024] The components of this utility model include a fixed housing-1, a supporting slide rail-2, a fixed side frame-3, a control box-4, a limiting side plate-5, an expansion and contraction drum-6, an adjusting rod-7, a receiving plate-8, a fixed side plate-9, a lifting top plate-10, a control module-11, a second hydraulic column-12, a pulley-13, a limiting side block-14, a first hydraulic column-15, a fixing groove-16, a rotating sleeve-17, a drive box-18, a fixed slide rod-19, a connecting block-20, and a fixing insertion hole-21. All components are general standard parts or parts known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. The problem solved by this utility model is that after the coiled material is placed on the expansion and contraction drum, it is necessary to manually rotate the adjusting column in the expansion and contraction drum to fix the coiled material, which is relatively cumbersome. The present invention addresses the technical problem of inconvenience caused by the inability to quickly place new rolls after a single roll has been fed, which affects the efficiency of roll processing. Through the combination of the aforementioned components—including the fixed housing, supporting slide rail, drive box, rotating sleeve, and receiving plate—the rolls can be easily moved and gradually placed onto the expanding and contracting drum. After the rolls are placed, the rotating sleeve can be installed on the drive end of the drive box. At this point, the rotating sleeve and the adjusting rod are on the same horizontal line. By gradually moving the fixed housing and inserting the rotating sleeve onto the adjusting rod, the drive box can be activated. The drive box drives the adjusting rod to rotate automatically, gradually opening the expanding and contracting drum and supporting and fixing the middle of the roll. This eliminates the need for manual rotation of the adjusting rod, improving the convenience of fixing.
