Description

Technical Field

[0001] This utility model relates to the field of tape roller installation technology, and in particular to a high-efficiency roller assembly for tape production. Background Technology

[0002] In actual tape production environments, when tape slitting machines are winding tape, they need to cut the tape into tapes with smaller widths for winding. Usually, multiple small winding drums are fixedly installed on a winding roller shaft for winding. The winding tension and winding diameter can be adjusted as needed. Before winding, the roller shaft needs to be disassembled. First, multiple winding drums are installed on the roller shaft, and then the roller shaft with the winding drums installed is installed on the slitting machine.

[0003] However, existing tape winding rollers are inconvenient to install or remove from slitting machines. They require first placing the roller into the groove, then covering it with a limit ring, and finally securing the limit ring – a rather cumbersome process. Therefore, this paper proposes a high-efficiency roller assembly for tape production. Utility Model Content

[0004] To solve the technical problem of tape roller installation, this utility model provides a high-efficiency roller assembly for tape production.

[0005] This utility model is achieved using the following technical solution: a high-efficiency roller assembly for tape production, comprising a roller and a fixed plate, a rotating cylinder rotatably connected to the fixed plate, a first limiting platform fixedly connected to the side of the rotating cylinder near the roller, a second limiting platform slidably connected to the inner side of the first limiting platform, an insertion rod fixedly connected to the side of the second limiting platform near the roller, slots being provided at both ends of the roller, the slots being inserted into one end of the insertion rod, a clamping and fixing mechanism being provided on the first limiting platform, and a roller drive mechanism for rotating the roller being provided on the side of the fixed plate away from the roller.

[0006] As a further improvement to the above solution, the clamping and fixing mechanism includes multiple No. 1 slots opened on the No. 1 limiting platform. The multiple No. 1 slots are arranged in a circumferential array. A No. 1 clamping block is slidably connected to the inner side of each of the multiple No. 1 slots. A connecting plate is fixedly connected to the side of each No. 1 clamping block near the roller shaft. A clamping block is fixedly connected to the end of each connecting plate near the roller shaft. The multiple clamping blocks are configured to cooperate with one end of the roller shaft. A clamping block driving mechanism is provided on the No. 2 limiting platform to enable the multiple clamping blocks to open and close with each other.

[0007] As a further improvement to the above solution, the clamping block driving mechanism includes multiple second slots opened on the second limiting platform. The multiple second slots are arranged in a circumferential array, and a wedge-shaped push block mechanism is provided on the inner side of each second slot.

[0008] As a further improvement to the above solution, the wedge-shaped pusher mechanism includes a second wedge-shaped block that is fixedly connected to one side of each of the first-shaped blocks. Each second wedge-shaped block is paired with each second slot, and the second wedge-shaped block is slidably connected to the inside of the second slot.

[0009] As a further improvement to the above solution, the roller drive mechanism includes a hydraulic cylinder fixedly connected to one side of the roller shaft of the rotating drum, the output end of the hydraulic cylinder being fixedly connected to the second limiting platform, and a rotating drum drive mechanism for rotating the rotating drum being provided on one side of the fixed plate.

[0010] As a further improvement to the above solution, the rotary drum drive mechanism includes a servo motor fixedly connected to one side of the fixed plate, a gear fixedly connected to the output end of the servo motor, and a gear ring fixedly connected to the outer side of the rotary drum, the gear ring meshing with the gear.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. The slot on the roller shaft of this utility model is inserted into the insertion rod, and then the oil cylinder is started to push the second limiting platform to slide to one side. The second slot pushes the second wedge-shaped block to make the clamping block self-center and fix and hold the outside of the roller shaft, realizing the quick and safe disassembly or disassembly of the tape roller shaft, which can significantly improve the efficiency of operators in disassembling or installing the roller shaft.

[0013] 2. This utility model achieves the installation and fixation of the roller shaft by sliding the second wedge-shaped block in the second slot and the first block sliding inside the first slot, under the action of the oil cylinder pushing the second limiting platform to slide inside the first limiting platform. The roller shaft assembly has the advantages of strong wear resistance, long service life and simple maintenance. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0021] Example:

[0022] Please combine Figures 1-4 This embodiment of a high-efficiency roller assembly for tape production includes a roller 2 and a fixing plate 1. The roller 2 is an air-expanding shaft that can fix the tape roll from the inside out. A rotating drum 6 is rotatably connected to the fixing plate 1. The rotating drum 6 has a hollow structure, and the internal space allows the output end of the hydraulic cylinder 12 to move through. A first limiting platform 7 is fixedly connected to the side of the rotating drum 6 near the roller 2. The first limiting platform 7 has a hollow frustum structure. A second limiting platform 8 is slidably connected to the inner side of the first limiting platform 7. The second limiting platform 8 has a frustum structure. An insertion rod 9 is fixedly connected to the side of the second limiting platform 8 near the roller 2. In this embodiment, the insertion rod 9 has a hexagonal structure. Slots 3 are provided at both ends of the roller 2. The slots 3 are hexagonal grooves. The slots 3 are inserted into one end of the insertion rod 9. When the insertion rod 9 rotates, it can push the roller 2 to rotate. A clamping and fixing mechanism is provided on the first limiting platform 7. A roller drive mechanism for rotating the roller 2 is provided on the side of the fixing plate 1 away from the roller 2.

[0023] Please combine Figure 3 As shown, the clamping and fixing mechanism includes three No. 1 slots 14 opened on the No. 1 limiting platform 7. The No. 1 slots 14 are T-shaped slot structures. Two No. 1 slots 14 are arranged in a circumferential array. The inner sides of the three No. 1 slots 14 are respectively slidably connected to No. 1 blocks 15. The No. 1 blocks 15 are T-shaped blocks. Each No. 1 block 15 is fixedly connected to a connecting plate 5 near the side including the roller shaft 2. Each connecting plate 5 is fixedly connected to a clamping block 4 near the end of the roller shaft 2. The clamping block 4 is a fan-shaped three-dimensional structure, made of composite industrial rubber material, which has excellent toughness and friction coefficient. When the clamping block 4 clamps the roller shaft 2, the inner surface of the clamping block 4 can undergo elastic deformation. The three clamping blocks 4 are set to cooperate with one end of the roller shaft 2. The No. 2 limiting platform 8 is provided with a clamping block driving mechanism that enables the multiple clamping blocks 4 to open and close with each other.

[0024] Please combine Figure 3As shown, the clamping block driving mechanism includes three second-position slots 17 opened on the second-position limiting stage 8. The structural features of the second-position slots 17 should be specifically noted, such as... Figure 4 As shown, this embodiment features an inclined design, with three second slots 17 arranged in a circular array, and each second slot 17 has a wedge-shaped pusher mechanism on its inner side.

[0025] Please combine Figure 4 As shown, the wedge-shaped pusher mechanism includes a second wedge-shaped block 16 that is fixedly connected to one side of multiple first-position locking blocks 15. The second wedge-shaped block 16 and the internal structure of the second-position locking slot 17 cooperate with each other. When the second-position limiting platform 8 moves towards the side closer to the roller shaft 2, the second wedge-shaped block 16 moves towards the center, and the clamping block 4 closes. When the second-position limiting platform 8 moves away from the roller shaft 2, the second wedge-shaped block 16 moves away from the center, and the clamping block 4 opens. Each second wedge-shaped block 16 is paired with each second-position locking slot 17, and the second wedge-shaped block 16 is slidably connected inside the second-position locking slot 17.

[0026] Please combine Figure 2 As shown, the roller drive mechanism includes a hydraulic cylinder 12 fixedly connected to one side of the roller 2 of the rotating drum 6. The output end of the hydraulic cylinder 12 is fixedly connected to the second limit platform 8. A rotating drum drive mechanism for rotating the rotating drum 6 is provided on one side of the fixed plate 1.

[0027] Please combine Figure 2 As shown, the rotary drum drive mechanism includes a servo motor 13 fixedly connected to one side of the fixed plate 1, a gear 11 fixedly connected to the output end of the servo motor 13, and a gear ring 10 fixedly connected to the outer side of the rotary drum 6, with the gear ring 10 meshing with the gear 11.

[0028] The implementation principle of a high-efficiency roller assembly for tape production in this embodiment is as follows: The operator inserts a roller 2, which has multiple rolls installed, into the insert rod 9 through the slot 3. Then, the hydraulic cylinder 12 is activated, pushing the second limiting platform 8 to slide along the inside of the first limiting platform 7 towards one side of the roller 2. At this time, under the pushing action of the second limiting platform 8, the insert rod 9 moves to one side, so that the other end of the roller 2 is just inserted into the limiting groove on the other side. Simultaneously, when the second limiting platform 8 moves, the second slot 17 opened on the second limiting platform 8... Due to the inclined design and wedge-shaped squeezing action, the second wedge-shaped clamping block 16 and the first clamping block 15 can be indirectly pulled to slide inward towards the center. At this time, each first clamping block 15 drives the connecting plate 5 and clamping block 4 on one side to move inward simultaneously, so as to achieve the effect of multiple clamping blocks 4 self-centering and clamping the outer side of the roller shaft 2. Then, the servo motor 13 is started to drive the gear 11 to rotate. Since the gear 11 meshes with the gear ring 10, it achieves the effect of pushing the rotating drum 6 to rotate along the fixed plate 1, and finally achieves the effect of the roller shaft 2 rotating to drive multiple rolls to wind up the tape.

[0029] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
