Description
Technical Field
[0001] This utility model relates to the field of sheet material processing technology, specifically a sheet bonding material winding machine. Background Technology
[0002] A sheet bonding rewinding machine is an industrial device used to automatically rewind continuously produced sheet materials. Its core function is to ensure that the material is uniformly wound into a roll under high-speed and high-precision conditions, while maintaining the material's flatness, tension stability, and edge alignment. Existing sheet bonding rewinding machines typically achieve continuous production through automatic bonding technology. However, after rewinding, existing equipment lacks efficient automatic cutting and station switching mechanisms, requiring manual intervention or machine downtime, leading to reduced production efficiency, especially in high-speed production lines where rapid roll changeover is difficult.
[0003] Based on this, a sheet bonding material winding machine is now provided, which can eliminate the drawbacks of existing equipment. Utility Model Content

The casters are fixedly installed at the bottom of the box, and a door is provided at the front end of the box. The top of the box is fixedly equipped with a winding mechanism for winding the material and the release film, and the top of the box is fixedly equipped with a cutting mechanism for automatically cutting the wound bonding material.
[0007] Based on the above technical solutions, this utility model also provides the following optional technical solutions:

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] 1. This utility model utilizes a dual-roller system for coordinated winding. The upper roller supplies the release film, while the lower roller winds up the composite material. A motor-driven gear set synchronizes the rotation of the two rollers, drawing the material to the film for lamination. An adjusting block vertically positions the lower roller, and a locking mechanism ensures stability. The dual-roller system integrates the lamination and winding functions. The symmetrical winding mechanism, combined with a cutting device, enables rapid switching without stopping the machine, enhancing continuous production capacity. It is suitable for high-precision, high-efficiency lamination processing of roll materials.
[0017] 2. This utility model uses a cylinder to push the third sliding plate axially, which in turn drives the rotating seat to rotate via the second connecting rod. This rotation is then converted into linear displacement of the mounting plate via the first connecting rod, causing the cutter to close and shear the material against the pad. The return spring stores energy during cutting and releases its elastic force to reset when the cylinder retracts. The mechanical linkage achieves progressive application of cutting force, ensuring smooth cutting and neat cuts. The overall structure is compact, and the operation is continuous and efficient, making it suitable for high-stability continuous cutting operations of composite materials.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0025] In one embodiment, such as Figures 1-5 As shown, the sheet bonding material winding machine includes: a box body 1, casters 2, a winding mechanism and a cutting mechanism. The casters 2 are fixedly installed at the bottom of the box body 1. The front end of the box body 1 is provided with a door 3. The top of the box body 1 is fixedly provided with a winding mechanism for winding the material and the release film. The top of the box body 1 is fixedly provided with a cutting mechanism for automatically cutting the wound bonding material.
[0026] The front end of the housing 1 is equipped with a display panel 32 and a control button 33. The device can be started and stopped by controlling the control button 33, and the operating status of the equipment can be observed on the display panel 32.
[0027] In one embodiment, such as Figures 2-4 As shown, the winding mechanism includes a support rod 4 fixedly mounted on the top of the housing 1. A mounting block 5 is fixedly mounted on the top of the support rod 4. An adjusting block 6 is slidably mounted on the support rod 4. A sliding rod 7 is fixedly mounted on the front end of the mounting block 5 and the adjusting block 6. A limiting block 8 is fixedly mounted on the sliding rod 7. An upper winding roller 9 is rotatably mounted on the sliding rod 7 at the front end of the mounting block 5. A lower winding roller 10 is rotatably mounted on the sliding rod 7 at the front end of the adjusting block 6. A locking block 11 is slidably mounted on the sliding rod 7. A locking knob 12 is threadedly fixedly mounted on the right side of the locking block 11. A guiding mechanism for guiding materials is rotatably mounted on the inner wall of the housing 1.
[0028] The sliding rod 7 is provided with a sliding groove that matches the locking block 11. The inner wall of the locking block 11 is provided with a limiting protrusion that matches the sliding groove, which facilitates the sliding installation of the locking block 11 and prevents the locking block 11 from rotating.
[0029] The upper take-up roller 9 is wound with a release film. The function of the lower take-up roller 10 is to wrap the material with the release film and take it up. The operator can adjust the height of the adjusting block 6 to adjust the height of the lower take-up roller 10, and then fix the position with bolts. The upper take-up roller 9 and the lower take-up roller 10 are slidably set on the sliding rod 7 and limited by the limiting block 8. Then the locking block 11 is slidably installed and limited by the lower take-up roller 10. Finally, the locking knob 12 is tightened to lock the locking block 11, so that the lower take-up roller 10 can rotate on the sliding rod 7.
[0030] The guiding mechanism includes a first gear 13 rotatably mounted on the inner wall of the housing 1, a second gear 14 rotatably mounted on the inner wall of the housing 1, a transmission belt 15 on the outer side of the first gear 13 and the second gear 14, two rotating rods rotatably mounted on the inner wall of the housing 1, the ends of the two rotating rods 16 being fixedly connected to the central shafts of the first gear 13 and the second gear 14 respectively, and a drive roller 17 being fixedly mounted on each rotating rod 16. A mounting bracket 18 is fixedly mounted on the outer side of the housing 1, and a motor 19 is fixedly mounted on the top of the mounting bracket 18. The output end of the motor 19 is fixedly connected to the central shaft of the first gear 13.
[0031] The top of the housing 1 has an opening that matches the drive roller 17, which facilitates the rotation of the drive roller 17 and also allows the material to be inserted through the opening and passed under the drive roller 17. The transmission belt 15 has meshing teeth that match the first gear 13 and the second gear 14.
[0032] During operation, the release film on the upper take-up roller 9 must first be pulled out and the end of the release film is attached to the lower take-up roller 10. Then, the material processed by the extruder enters through the opening at the top of the housing 1, passes under the drive roller 17, and is pulled out from the left side of the drive roller 17. The end of the drive roller 17 is attached to the lower take-up roller 10 and adheres to the release film. Then, the height of the lower take-up roller 10 is adjusted so that it connects with the drive roller 17. The output end of the motor 19 drives the first gear 13 to rotate. The first gear 13 drives the second gear 14 to mesh and rotate through the transmission belt 15, so that the two drive rollers 17 rotate synchronously and assist the operator in rotating and winding the lower take-up roller 10. The device is equipped with two winding mechanisms on the left and right sides. After the left side is wound up, the cutting mechanism can be controlled to cut the material and release film and quickly connect the material to the right side winding mechanism, thereby improving the winding efficiency.
[0033] In one embodiment, such as Figure 5 As shown, the cutting mechanism includes a cutting bracket 20 fixedly mounted on the top of the housing 1. A guide rod 21 is fixedly mounted on the inner wall of the cutting bracket 20. A first mounting plate 22 and a second mounting plate 23 are slidably mounted on the guide rod 21. A return spring 24 is fixedly connected between the first mounting plate 22 and the second mounting plate 23, and the return spring 24 is sleeved around the periphery of the guide rod 21. A third sliding plate 25 is slidably mounted on the guide rod 21. A cutter 26 is fixedly mounted on the right side of the second mounting plate 23. A cutting pad 27 is fixedly mounted on the left side of the third sliding plate 25. A drive mechanism for driving the cutter 26 to perform a closed cutting action is rotatably mounted on the inner wall of the cutting bracket 20.
[0034] The driving mechanism includes a rotating seat 28 rotatably mounted on the inner wall of the cutting bracket 20, a first connecting rod 29 rotatably mounted at both ends of the first mounting plate 22, the other end of the first connecting rod 29 being rotatably connected to one end of the rotating seat 28, a second connecting rod 30 rotatably mounted at both ends of the third sliding plate 25, the other end of the second connecting rod 30 being rotatably connected to the other end of the rotating seat 28, and a cylinder 31 fixedly mounted on the right side of the cutting bracket 20, the output end of the cylinder 31 being fixedly connected to the right side of the third sliding plate 25.
[0035] The cylinder 31 pushes the third sliding plate 25. When the third sliding plate 25 slides along the guide rod 21, it drives the second connecting rods 30 at both ends to move. The other end of the second connecting rod 30 drives the rotating seat 28 to rotate. When the rotating seat 28 rotates, it drives the first connecting rod 29 to rotate, so that the first connecting rod 29 drives the first mounting plate 22 to slide. The first mounting plate 22 slides synchronously with the second mounting plate 23 under the setting of the return spring 24, so that the second mounting plate 23 and the third sliding plate 25 close, and drive the cutter 26 to cut the bonding material. After the cutter 26 and the cutting pad 27 close, the cutter 26 slides and compresses the return spring 24. When the cylinder 31 drives the third sliding plate 25 to reset, the return spring 24 resets and drives the second mounting plate 23 to reset.
[0036] The above embodiments disclose a sheet bonding material winding machine, wherein the device adopts a dual-roller cooperative winding mechanism, with the upper winding roller 9 serving as the supply end of the release film and the lower winding roller 10 serving as the winding end of the composite material. The operator achieves vertical positioning of the lower winding roller 10 by adjusting the height of the adjusting block 6, and the height is locked by bolts. The sliding rod 7 and the limiting block 8 constitute an axial positioning assembly, which, in conjunction with the sliding installation of the locking block 11 and the threaded fastening of the locking knob 12, ensures the stability of the lower winding roller 10 under rotational conditions. In the working process, the release film of the upper winding roller 9 is first pulled to the lower winding roller 10 for end bonding. After the material is introduced from the opening at the top of the housing 1, it forms a wrapping path below the drive roller 17, and is drawn out from the left side of the drive roller 17 and synchronously bonded with the release film. The first gear 13 is driven to rotate by the motor 19, and the second gear 14 is driven by the transmission belt 15 to form a meshing transmission, causing the two drive rollers 17 to rotate synchronously. The contact pressure control between the lower winding roller 10 and the drive roller 17 is achieved by adjusting the height of the lower winding roller 10. The symmetrically arranged winding mechanisms enable continuous operation. When the left winding is complete, the material and release film are cut by the cutting mechanism, and the operation is quickly switched to the right winding mechanism to continue. When the output end of the cylinder 31 pushes the third sliding plate 25 to slide axially along the guide rod 21, it causes the second connecting rods 30 at both ends to move. The movement of the second connecting rods 30 forces the rotating seat 28 to rotate around its axis, and the rotational motion is converted into the linear displacement of the first mounting plate 22 through the first connecting rod 29. Under the elastic action of the return spring 24, the second mounting plate 23 and the third sliding plate 25 form a synchronous closing motion, so that the cutter 26 and the cutting pad 27 complete the shearing action on the composite material. During the cutting process, the continuous feed of the cutter 26 compresses the return spring 24 to generate stored energy. When the cylinder 31 retracts and drives the third sliding plate 25 to reset, the return spring 24 releases its elastic force to drive the second mounting plate 23 back to its initial position. This mechanism achieves gradient application of cutting force through mechanical linkage, ensuring the smoothness of the cutting action.
[0037] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
