Abstract
Description
Technical Field
[0001] This utility model relates to the field of paper tube processing technology, specifically a square tube cap folding device. Background Technology
[0002] Paper tubes are cylindrical structures made of paper and used as packaging containers. They are usually made of kraft paper, which enhances the structural strength of the paper tube. They can be processed into square or round paper tubes as needed.
[0003] After processing the square paper tube, the tube cap is processed accordingly. Generally, a square frame is placed on the outside of the mold, and then a cylinder is used to push the pressure plate from both sides to bend the side of the square frame that protrudes from the mold, thus achieving the function of folding the edge. After the edge is folded, it is necessary to manually use a rubber mallet to tap the corners to shape the edge. This increases the labor intensity of the workers and affects the folding efficiency. Therefore, further improvements can be made. Utility Model Content
[0004] To address the aforementioned problems, this utility model provides the following technical solution: a square cylindrical cap folding device, comprising a base, a processing table fixedly mounted on the top center of the base, a series of grooves formed on the top of the processing table, inner support plates provided on the top side of the processing table corresponding to the grooves, a transmission assembly for driving the four inner support plates to move relative to each other inside the processing table, folding components for folding the cylindrical cap provided on the top of the base and on both sides of the processing table, a bracket fixedly mounted on the back center of the base, and an electric slide rail provided on one side of the front of the bracket. An electric slider is slidably connected to the outer side of the electric slide rail. A shaping component for striking the four corners of the paper tube lid is provided on one side of the front of the electric slider. The transmission component drives the inner support plates on the four sides to move relative to each other, thereby adjusting the outer diameter. This makes it convenient to position square paper tube lids of different sizes. The paper tube lid can be folded by the folding components on both sides. Finally, the electric slider slides up and down along the electric slide rail, which drives the shaping component to strike the four corners of the folded lid, thereby stabilizing the folded paper tube and improving work efficiency.
[0005] As an optimization, the transmission assembly includes a screw rotatably connected in a slide groove, a movable block slidably connected inside the slide groove, and an inner support plate fixedly installed on the top side of the movable block. The screw is screwed into the inner center of the movable block, and a driven bevel gear is fixedly installed at one end of the screw that enters the inner center of the processing table. A main bevel gear is rotatably connected to the inner center of the processing table, and the main bevel gear and the driven bevel gear are meshed. The rotation of the main bevel gear drives the movable block to slide along the inner wall of the slide groove, which in turn causes the inner support plates on the four sides to slide closer or further away.
[0006] As an optimization, the two sets of screws that are relatively mirror-symmetrical have opposite thread directions, ensuring that when the screws on both sides rotate inside the movable blocks, they can drive the movable blocks on both sides to slide relatively synchronously.
[0007] As an optimization, the folding assembly includes a support fixedly installed on the top side of the base, an electric telescopic rod fixedly installed on the top of the support, and a limit frame fixedly installed on the opposite side of both supports. An L-shaped folding plate is slidably connected inside the limit frame. A support plate is fixedly installed in the middle of the L-shaped folding plate, and the telescopic end of the electric telescopic rod is fixedly installed on one side of the support plate. The side of the cylinder cover can be bent by pushing the L-shaped folding plate.
[0008] As an optimization, the bottom horizontal plane of the L-shaped folding plate is located above the top side of the inner support plate, and a gap is left between the bottom side of the L-shaped folding plate and the top side of the inner support plate to facilitate the folding of the paper tube cover.
[0009] As an optimization, the shaping component includes a fixed plate fixedly installed on one side of the front of the electric slider, a lifting plate fixedly installed on the other end of the fixed plate, limit cylinders fixedly installed at the four corners of the lifting plate, guide rods slidably inserted inside the limit cylinders, pressure plates fixedly installed at the bottom ends of the guide rods, and springs fixedly installed between the pressure plates and the lifting plate. By tapping the four corners of the folded paper tube cover back and forth by the pressure plates, manual operation can be replaced.
[0010] As an optimization, the spring is sleeved on the outside of the guide rod, and a rubber pad is provided on the bottom side of the pressure plate. Through the elastic force of the spring itself and the rubber pad that is in direct contact with the paper tube cover, the pressure plate can flexibly strike the four corners of the paper tube cover, avoiding hard impact that could damage the paper tube cover.
[0011] The beneficial effects of this utility model are: 1. The square tube cap folding device, through the rotation of the main bevel gear, drives the driven bevel gear to rotate synchronously, which in turn drives the screw to rotate inside the movable block. Therefore, the movable block slides along the inner wall of the slide groove, which in turn drives the inner support plates on the four sides to slide closer or further away, thereby adjusting the outer diameter to suit different paper tube caps, thus improving practicality.
[0012] 2. This square tube lid folding device uses an electric slider to slide up and down along the outside of the electric slide rail, which drives the lifting plate to move synchronously. This causes the pressure plate to tap the four corners of the folded paper tube lid back and forth, thus replacing manual operation, reducing labor intensity, and improving work efficiency. Furthermore, through the elasticity of the spring itself and the rubber pad that is in direct contact with the paper tube lid, the pressure plate gently taps the four corners of the paper tube lid to shape it, thereby avoiding hard knocking that could damage the paper tube lid.

[0015] In the description of this application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figure 1A square cylindrical cap folding device includes a base 1, a processing table 2 fixedly mounted on the top center of the base 1, a sliding groove arrayed on the top of the processing table 2, an inner support plate 3 provided on the top side of the processing table 2 corresponding to the sliding groove, a transmission assembly for driving the four inner support plates 3 to move relative to each other inside the processing table 2, folding components 4 for folding the cylindrical cap are provided on the top of the base 1 and on both sides of the processing table 2, a bracket 5 fixedly mounted on the back center of the base 1, an electric slide rail 6 provided on one side of the front of the bracket 5, and a sliding connection on the outer side of the electric slide rail 6. The electric slider 7 has a shaping component 8 on one side of its front for striking the four corners of the paper tube lid. The transmission component drives the inner support plates 3 on the four sides to move relative to each other, thereby adjusting the outer diameter. This makes it convenient to position square paper tube lids of different sizes. The paper tube lid can then be folded by the folding components 4 on both sides. Finally, the electric slider 7 slides up and down along the electric slide rail 6, which drives the shaping component 8 to strike the four corners of the folded lid, thereby stabilizing the folded paper tube and improving work efficiency. Please see Figure 2 The transmission assembly includes a screw 9 rotatably connected in a slide groove, a movable block 10 slidably connected inside the slide groove, and an inner support plate 3 fixedly installed on the top side of the movable block 10. The screw 9 is screwed into the inner center of the movable block 10. The two sets of screws 9, which are relatively mirror-symmetrical, have opposite thread directions, ensuring that when the screws 9 on both sides rotate inside the movable block 10, they can drive the movable blocks 10 on both sides to slide synchronously. A driven bevel gear 11 is fixedly installed at one end of the screw 9 that enters the inner center of the processing table 2. A main bevel gear 12 is rotatably connected to the inner center of the processing table 2, and the main bevel gear 12 and the driven bevel gear 11 are meshed. By starting the motor to drive the main bevel gear 12 to rotate, the driven bevel gear 11 can drive the screw 9 to rotate inside the movable block 10, thus causing the movable block 10 to slide along the inner wall of the slide groove. This will cause the inner support plates 3 on the four sides to slide closer or further away, thereby facilitating the adjustment of the outer diameter to suit different paper tube caps. Please see Figure 3 The folding assembly 4 includes a support 13 fixedly installed on the top side of the base 1. An electric telescopic rod 14 is fixedly installed on the top of the support 13. Limit frames 15 are fixedly installed on opposite sides of the two supports 13. An L-shaped folding plate 16 is slidably connected inside the limit frame 15. The bottom horizontal plane of the L-shaped folding plate 16 is located above the top side of the inner support plate 3, and there is a gap between the bottom side of the L-shaped folding plate 16 and the top side of the inner support plate 3 to facilitate folding the paper tube cover. A support plate 17 is fixedly installed in the middle of the L-shaped folding plate 16, and the telescopic end of the electric telescopic rod 14 is fixedly installed on one side of the support plate 17. By activating the electric telescopic rod 14, the L-shaped folding plate 16 will be pushed to slide along the inner wall of the limit frame 15, thereby causing the L-shaped folding plate 16 to bend the side of the tube cover, thus achieving the folding effect. Please see Figure 4 The shaping component 8 includes a fixed plate 18 fixedly installed on one side of the front of the electric slider 7. A lifting plate 19 is fixedly installed on the other end of the fixed plate 18. Limiting cylinders 20 are fixedly installed at the four corners of the lifting plate 19. A guide rod 21 is slidably inserted into the inside of the limiting cylinder 20. A pressure plate 22 is fixedly installed at the bottom end of the guide rod 21. A spring 23 is fixedly installed between the pressure plate 22 and the lifting plate 19. The spring 23 is sleeved on the outside of the guide rod 21. A rubber pad is provided on the bottom side of the pressure plate 22. By sliding the electric slider 7 up and down along the outside of the electric slide rail 6, the lifting plate 19 can be moved synchronously, which will cause the pressure plate 22 to knock back and forth on the four corners of the folded paper tube cover. Therefore, it can replace manual operation, reduce labor intensity, and improve work efficiency. Moreover, through the elasticity of the spring 23 itself and the rubber pad that is in direct contact with the paper tube cover, the pressure plate 22 can flexibly knock on the four corners of the paper tube cover, avoiding hard knocking and damaging the paper tube cover.
[0018] In use, first, start the built-in motor to drive the main bevel gear 12 to rotate. Then, the screw 9 will rotate inside the movable block 10 through the bevel gear 11. This will cause the movable block 10 to slide along the inner wall of the slide groove. This will cause the four inner support plates 3 to slide closer or further away from each other, so that the outer diameter can be adjusted to suit different paper tube caps. Then, the paper tube cap can be put on the outside of the four sets of inner support plates 3. Then, start the electric telescopic rod 14 to push the L-shaped folding plate 16 to slide along the inner wall of the limit frame 15. This will cause the L-shaped folding plate 16 to bend the side of the cap for folding. Then, by sliding the electric slider 7 up and down along the outside of the electric slide rail 6, the lifting plate 19 can be moved synchronously, which in turn will cause the pressure plate 22 to knock back and forth on the four corners of the folded paper tube cover. Therefore, it can replace manual operation, reduce labor intensity, and improve work efficiency.
[0019] In summary, the square tube cap folding device, through the rotation of the main bevel gear 12, drives the secondary bevel gear 11 to rotate synchronously, which in turn drives the screw 9 to rotate inside the movable block 10. Therefore, the movable block 10 will slide along the inner wall of the slide groove, which will in turn drive the inner support plates 3 on the four sides to slide closer or further away, thereby adjusting the outer diameter to suit different paper tube caps, thus improving practicality.
[0020] By sliding the electric slider 7 up and down along the outer side of the electric slide rail 6, the lifting plate 19 can be moved synchronously, which will cause the pressure plate 22 to knock back and forth on the four corners of the folded paper tube cover. This can replace manual operation, reduce labor intensity, and improve work efficiency. Furthermore, through the elasticity of the spring 23 itself and the rubber pad that is in direct contact with the paper tube cover, the pressure plate 22 can gently knock on the four corners of the paper tube cover to shape it, thereby avoiding hard knocking that could damage the paper tube cover.
