Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, specifically to an automatic waste edge winding machine for tape production. Background Technology

[0002] Packaging tape is a type of BOPP tape made by applying pressure-sensitive adhesive emulsion evenly with heated BOPP biaxially oriented polypropylene film as the base material. The resulting tape master roll is then cut and rewound into smaller rolls with smaller diameters, thus obtaining the packaging tape we use daily.

[0003] Before the adhesive coating process in tape production, the tape raw material needs to be cut to make its edges flat and aesthetically pleasing. The cut waste edges need to be collected and centrally processed. Existing patent CN218707840U discloses a waste edge collection device for tape production, which relates to the field of waste edge collection technology. It includes a base, a support column installed on the top of the base, a through groove on the support column, and a sliding groove on the side of the support column. The sliding groove is connected to the through groove, and a fixing plate is fixed to the inner top and inner bottom of the sliding groove.

[0004] Although this device realizes the height adjustment function of the take-up roller to adjust the distance between the take-up roller and the guide roller, thereby facilitating the winding of different amounts of tape waste, the tape waste is generally narrow and easily piles up in one place during winding, resulting in a relatively small winding amount. Therefore, we propose an automatic waste edge winding machine for tape production to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an automatic waste edge winding machine for tape production, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic waste edge winding machine for tape production, comprising a frame, with mounting components rotatably connected to both sides of the frame, the mounting components respectively locking the two ends of a receiving roller, the taking-up roller being disposed within the frame, a servo motor output shaft fixedly connected to one end of the mounting component away from the taking-up roller on one side, the servo motor being fixedly mounted on the frame, a small gear fixedly connected to the other end of the mounting component away from the taking-up roller on the other side, the small gear meshing with a large gear, the large gear fixedly sleeved on one side of a cylindrical cam, one end of the cylindrical cam rotatably connected to the frame, a roller provided in the groove of the cylindrical cam, the roller rotatably sleeved on one end of a connecting rod, the other end of the connecting rod fixedly connected to one side outer wall of a movable rod, the movable rod slidably sleeved in a sliding opening, the sliding opening being opened at the top of the frame on the side away from the mounting components, a guide frame fixedly connected to the bottom of the movable rod, the guide frame being movably disposed within the frame.

[0007] Preferably, both the frame and the guide frame are U-shaped structures.

[0008] Preferably, the movable rod has a rectangular structure.

[0009] Preferably, the take-up roller has slots at both ends.

[0010] Preferably, the mounting assembly includes a U-shaped base, fixing bolts, a rotating shaft, and nuts. One end of the rotating shaft is rotatably connected to the frame, and the opposite end of the rotating shaft is fixedly connected to one end of the U-shaped base. The opening of the U-shaped base has through holes on both sides, and fixing bolts are inserted into the holes. The fixing bolts abut against the bayonet, and one end of the fixing bolts is threaded with nuts.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. The installation components facilitate the disassembly and assembly of the take-up roller. When it is necessary to replace the take-up roller or clean the waste edge roll, simply unscrew the nut and loosen the fixing bolt to remove the take-up roller from the opening of the U-shaped seat. The operation is convenient, time-saving and labor-saving, effectively improving the efficiency of equipment maintenance and waste edge processing. 2. The small gear drives the large gear to decelerate, and the large gear in turn drives the cylindrical cam to rotate in a circle. The cylindrical cam, together with the roller and connecting rod, drives the movable rod to move back and forth in a straight line. The movable rod then drives the guide frame to move back and forth synchronously, so that the waste edge of the tape can be evenly wound on the take-up roller under the guidance of the guide frame, avoiding the problem of waste edge accumulating in one place and reducing the take-up amount. 3. The servo motor drives the mounting components to rotate the take-up roller, realizing automatic winding of waste edges, which greatly reduces the intensity of manual labor and improves the automation level and work efficiency of waste edge collection in the tape production process.

[0014] 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.

[0015] Example 1 Reference Figure 1 , 2 This is the first embodiment of the present invention. This embodiment provides an automatic waste edge winding machine for tape production, including a frame 1. Mounting components 3 are rotatably connected to both sides of the frame 1. The mounting components 3 respectively hold the two ends of the receiving roller 12. The receiving roller 12 is located inside the frame 1. The end of one mounting component 3 away from the receiving roller 12 is fixedly connected to the output shaft of a servo motor 2. The servo motor 2 is fixedly mounted on the frame 1. The end of the other mounting component 3 away from the receiving roller 12 is fixedly connected to a small gear 4. The small gear 4 meshes with a large gear 5. The large gear 5 is fixedly sleeved on one side of a cylindrical cam 6. One end of the cylindrical cam 6 is rotatably connected to the frame 1. A roller 7 is provided in the groove of the cylindrical cam 6. The roller 7 is rotatably sleeved on one end of a connecting rod 8. The other end of the connecting rod 8 is fixedly connected to the outer wall of one side of a movable rod 9. The movable rod 9 is slidably sleeved in a sliding opening 10. The sliding opening 10 is opened at the top of the side of the frame 1 away from the mounting components 3. A guide frame 11 is fixedly connected to the bottom of the movable rod 9. The guide frame 11 is movably located inside the frame 1.

[0016] Example 2 Reference Figure 1-3 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. Specifically, both the frame 1 and the guide frame 11 are U-shaped structures, which facilitates the installation of various components inside the frame 1.

[0017] Specifically, the movable rod 9 has a rectangular structure, which, together with the rectangular sliding opening 10, enables the movable rod 9 to achieve linear motion.

[0018] Specifically, the take-up roller 12 has a latch 121 at each end. The latch 121, together with the fixing bolt 32 of the mounting component 3, can stably latch the take-up roller 12, preventing axial displacement or detachment of the take-up roller 12 during rotation, and ensuring the smooth operation of the take-up operation.

[0019] Specifically, the mounting assembly 3 includes a U-shaped base 31, fixing bolts 32, a rotating shaft 33, and nuts 34. One end of the rotating shaft 33 is rotatably connected to the frame 1, ensuring that the mounting assembly 3 can rotate stably with the drive of the servo motor 2. The opposite end of the rotating shaft 33 is fixedly connected to one end of the U-shaped base 31, providing support and installation space for both ends of the take-up roller 12. The opening of the U-shaped base 31 has through holes on both sides, and fixing bolts 32 are inserted into the holes. The fixing bolts 32 abut against the bayonet 121. By tightening the fixing bolts 32, the end of the take-up roller 12 can be firmly fixed in the U-shaped base 31. One end of the fixing bolt 32 is threaded with a nut 34. The nut 34 can further tighten the fixing bolt 32 to prevent it from loosening during equipment operation and improve the fixing reliability of the mounting assembly 3 for the take-up roller 12.

[0020] The working principle and process are as follows: When installing the take-up roller 12, firstly, use a tool (such as a wrench) to manually loosen the nut 34 of the installation component 3 so that the nut 34 is released from the fixing bolt 32. The fixing bolt 32 can then be pulled out from the U-shaped seat 31, and the take-up roller 12 can be removed from the opening of the U-shaped seat 31. Align the two ends of the new take-up roller 12 with the opening of the U-shaped seat 31, put the two ends of the take-up roller 12 into the U-shaped seat 31, and then pass the fixing bolt 32 through the round holes on both sides of the U-shaped seat 31 and lock it in the position of the bayonet 121. Next, screw the nut 34 into the threaded end of the fixing bolt 32, and tighten the nut 34 with a tool so that the fixing bolt 32 is tightly abutted against the bayonet 121, thus completing the installation and fixing of the take-up roller 12. When the waste edge winding operation is required, firstly, the waste edge of the tape is passed through the guide frame 11, and the first end of the waste edge of the tape is wound onto the take-up roller 12. The servo motor 2 is started, and the output shaft of the servo motor 2 drives the connected mounting assembly 3 to rotate. The mounting assembly 3 then drives the take-up roller 12 to rotate synchronously, starting to wind up the waste edge of the tape. At the same time, the mounting assembly 3 on the other side rotates under the drive of the take-up roller 12, and the small gear 4 at its end rotates accordingly. The small gear 4 meshes with the large gear 5 for transmission. Since the large gear 5 has more teeth than the small gear 4, it achieves deceleration. The large gear 5 drives the cylindrical cam 6 to rotate circumferentially at a slower speed. When the cylindrical cam 6 rotates, its inner wall of the groove interacts with the roller. 7 generates thrust, and the roller 7 rolls in the groove, driving the connecting rod 8 to move. The connecting rod 8 pulls or pushes the movable rod 9. The movable rod 9 makes reciprocating linear motion under the restriction of the sliding mouth 10. The guide frame 11 at the bottom of the movable rod 9 also moves reciprocally in the frame 1. Under the reciprocating guidance of the guide frame 11, the waste edge of the tape can be evenly distributed in different positions of the take-up roller 12, avoiding local accumulation. As the take-up roller 12 continues to rotate, the waste edge is neatly and tightly wound on the take-up roller 12 until the take-up roller 12 is fully wound with waste edge. Then, the servo motor 2 is turned off, and the take-up roller 12 is removed according to the reverse steps of the above installation. A new take-up roller 12 can be replaced to continue the waste edge winding operation.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
