Abstract
Description
Technical Field
[0001] This utility model relates to the field of laminating machine technology, and in particular to a continuous winding machine for laminating machines. Background Technology
[0002] A laminating machine is a specialized piece of equipment used for laminating paper, boards, and other materials. It combines rubber rollers and heated rollers under pressure to form a paper-plastic composite. In a typical laminating machine, the material to be laminated is fed between two rollers via a conveyor mechanism, and the film is applied to the surface of the material by the pressure of the rollers.
[0003] For example, the Chinese utility model patent CN215100872U, which discloses a winding device for a laminating machine, solves the problem of traditional laminating machines having a fixed pressure roller height, limiting their application to materials of the same thickness. It also avoids creases when collecting soft materials such as paper. However, this structure still has several significant drawbacks:
[0004] 1. Laminating machines generally use a single shaft to wind up materials. After the set length of winding is reached, the machine needs to be stopped to remove the fixed sheet that has been wound up, and then a new roll is installed. Finally, the machine is started to start the next round of winding. Therefore, the winding work is discontinuous and the production efficiency is low.
[0005] 2. When winding materials, the operator often relies on real-time observation and manual adjustment to ensure the neatness and accuracy of the materials. This not only increases labor intensity and production costs, but also makes it difficult to guarantee the stability and consistency of the winding of the roll material over a long period of time.

[0037] The following description, in conjunction with the accompanying drawings, details a continuous winding machine for a laminating machine provided in this application through specific embodiments and application scenarios.
[0038] Example 1:
[0039] like Figures 1 to 3 As shown in the figure, this application provides a continuous winding machine for a laminating machine, including a frame 1, a driving roller 2, and a driven roller 3. The frame 1 is characterized by having a winding assembly 4 and a spare winding assembly 5. Both the winding assembly 4 and the spare winding assembly 5 have the driven roller 3 movably mounted on them, and both can perform winding operations. After the winding assembly 4 finishes winding, the material on the driving roller 2 is cut by a cutting device 6 and continues to be wound onto the spare winding assembly 5. The frame 1 also has a storage roller assembly 7. The winding assembly 4 can transport the wound driven roller 3 onto the storage roller assembly 7, and the spare winding assembly 5 can transport the wound driven roller 3 onto the winding assembly 4 and reinstall a new driven roller 3.
[0040] Furthermore, the winding assembly 4 includes a first rotating shaft 41 and a first mounting bracket 42. The first rotating shaft 41 is rotatably mounted on the frame 1, and a pair of first mounting brackets 42 are fixedly mounted on the first rotating shaft 41. Each pair of first mounting brackets 42 is provided with a first mounting groove 43. A pair of first mounting blocks 31 are provided on the driven roller 3, and the pair of first mounting blocks 31 are rotatably mounted on the pair of first mounting grooves 43 respectively. The pair of first mounting brackets 42 can be driven to rotate by a first driving device 44.
[0041] Furthermore, the first drive device 44 includes a first cylinder 441. A pair of first cylinders 441 are rotatably mounted on the inner side of the frame 1. The output shafts of the pair of first cylinders 441 are respectively movably mounted on a pair of first mounting brackets 42. The pair of first cylinders 441 can drive the pair of first mounting brackets 42 to rotate. The driven roller 3 is rotatably mounted on the frame 1 through a pair of rolling grooves 32. The rotation of the pair of first mounting brackets 42 can drive the driven roller 3 to roll on the frame 1.
[0042] Furthermore, the storage and rolling assembly 7 includes a pair of second mounting brackets 71 and a second rotating shaft 74. The second rotating shaft 74 is rotatably mounted on the frame 1. The lower ends of the pair of second mounting brackets 71 are fixedly mounted on the second rotating shaft 74, and the upper ends of the pair are provided with second mounting slots 72. The driven roller 3 is provided with a pair of second mounting blocks 33, and the pair of second mounting blocks 33 can be respectively mounted on the pair of second mounting slots 72. Rotating blocks 75 are provided at both ends of the second rotating shaft 74. Drive cylinders 73 are rotatably mounted on both sides of the frame 1. The output shafts of the pair of drive cylinders 73 are respectively movably mounted on the pair of rotating blocks 75. The drive cylinders 73 can drive the pair of rotating blocks 75 to rotate.
[0043] Furthermore, the spare winding assembly 5 includes a pair of third mounting brackets 51 and a pair of connecting blocks 52. The pair of third mounting brackets 51 are rotatably mounted on the frame 1, and the pair of connecting blocks 52 are slidably mounted on the pair of third mounting brackets 51 via first slide rails 53. Each pair of connecting blocks 52 is provided with a third mounting groove 54. The driven roller 3 can be mounted on the pair of third mounting grooves 54 via a pair of second mounting blocks 33. The pair of connecting blocks 52 can slide along the first slide rail 53 via corresponding second drive devices 55.
[0044] Furthermore, the second drive device 55 includes a second cylinder 551 and a connecting plate 552. The second cylinder 551 is fixedly mounted on the third mounting bracket 51. One end of the connecting plate 552 is fixedly connected to the output shaft of the second cylinder 551, and the other end is fixedly connected to the connecting block 52.
[0045] Furthermore, each pair of connecting blocks 52 is provided with a sliding groove 56, and a sliding block 57 is slidably installed in each sliding groove 56. A third cylinder 58 is fixedly connected to each pair of connecting blocks 52. The output shafts of the third cylinders 58 are respectively fixedly connected to the pair of sliding blocks 57. The third cylinders 58 can push the pair of sliding blocks 57 respectively to close the third mounting groove 54.
[0046] In this embodiment of the application, due to the above-described structure, an active roller 2 is rotatably mounted on the frame 1. When the drive motor corresponding to the active roller 2 is started, the active roller 2 rotates and drives the driven roller 3 on the winding assembly 4 to rotate, so that the material is wound on the driven roller 3 on the winding assembly 4. When the driven roller 3 is full of a roll, the second cylinder 551 is started, and the connecting block 52 is pushed down through the connecting plate 552 to make the driven roller 3 on the standby winding assembly 5 come into contact with the material and stick to the material. At the same time as the material is stuck, the cutting device 6 will cut the material. At this time, the driven roller 3 on the standby winding assembly 5 begins to wind the material.
[0047] After the cutting device 6 cuts the material, the first pair of cylinders 411 are activated, pushing the first pair of mounting frames 42 to rotate. The rotation of the first pair of mounting frames 42 causes the driven roller 3 on the winding assembly 4 to roll on the frame 1 until the driven roller 3 on the winding assembly 4 is pushed into the second pair of mounting slots 72. The first pair of mounting frames 42 are reset by the first cylinder 411. At this time, the second pair of drive cylinders 73 are activated, pushing the second pair of rotating blocks 75 and the second rotating shaft 74 to rotate. The rotation of the second rotating shaft 74 causes the second pair of mounting frames 71 to rotate, and makes the opening of the second pair of mounting slots 72 face upward, so that the operator can take the driven roller 3 out of the second mounting slot 72.
[0048] After the pair of mounting brackets 42 are reset, the drive motor corresponding to the third mounting bracket 51 is started. The pair of third mounting brackets 51 rotate, driving the pair of connecting blocks 52 and the driven roller 3 mounted on them to rotate together until the rolling groove 32 of the driven roller 3 is engaged on the frame 1. The first mounting block of the driven roller 3 is placed in the first mounting groove 43. At this time, the third cylinder 58 is started. The output shaft of the third cylinder 58 drives the sliding block 57 to slide in the direction of the third cylinder 58. At this time, the third mounting groove 54 is opened, and the driven roller 3 is rotated and installed on the pair of first mounting grooves 43. The pair of third mounting brackets 51 are reset by the drive motor corresponding to the third mounting bracket 51. At this time, a new driven roller 3 can be reinstalled in the third mounting groove 54.
[0049] Example 2:
[0050] like Figure 2 , Figure 4 and Figure 5 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the frame 1 is provided with an anti-deviation device 8. The anti-deviation device 8 includes a connecting frame 81, which is fixedly installed on the frame 1. A pair of sliders 82 are slidably installed on the connecting frame 81. Each slider 82 is provided with a pressing member 83, which is used to prevent material deviation when the winding assembly 4 is winding. The spacing between the pair of sliders 82 can be adjusted by corresponding adjusting components 84.
[0051] Furthermore, the adjustment assembly 84 includes a gear 841 and a rack 842. The slider 82 is provided with a movable cavity 843, and the gear 841 is rotatably mounted in the movable cavity 843. The rack 842 is provided on the connecting frame 81, and the gear 841 and the rack 842 are meshed together. The slider 82 is provided with a motor 844, and the drive shaft of the motor 844 is fixedly connected to the gear 841.
[0052] Furthermore, the pressing member 83 includes a pressing roller 831 and a limiting block 834. The slider 82 is provided with a insertion hole 832, and an insertion block 833 is slidably installed in the insertion hole 832. One end of the insertion block 833 is fixedly connected to the pressing roller 831, and the other end is fixedly connected to the limiting block 834. A spring 835 is sleeved on the insertion block 833. One end of the spring 835 is fixedly connected to the limiting block 834, and the other end is fixedly connected to the slider 82.
[0053] In this embodiment of the application, due to the above-described structure, when the driven roller 3 is winding up the material, the operator can control a pair of motors 844 to start simultaneously via an external control center. The start of the pair of motors 844 will drive the corresponding gears 841 to rotate. Since the gears 841 are meshed with the rack 842, the rotation of the pair of gears 841 will drive the corresponding sliders 82 to slide in the direction of the material, so that the pressure rollers 831 on them press against both ends of the material, keeping the material always in the middle of the driven roller 3. The spring 835 provides a buffering effect on the pressure rollers 831, preventing the pressure rollers 831 from exerting excessive pressure on the material and avoiding damage to the material.
