Description

Technical Field

[0001] This utility model relates to the field of paper production technology, specifically a winding device with fixed-position cutting. Background Technology

[0002] A paper winding and cutting device is a piece of equipment that integrates paper winding and cutting functions, and is widely used in industries such as printing, packaging, and papermaking. This device has extensive applications in these industries. For example, in the printing industry, a paper winding and cutting device can wind up and cut printed paper, facilitating subsequent cutting, binding, and other processes.

[0003] Existing paper winding devices use a continuous paper speed, a serrated blade to quickly cut paper into segments, and a rubber roller to transfer subsequent paper onto a new winding mandrel. The structure is relatively simple, but it makes it difficult to determine the paper cut position, which can lead to damage to the finished labels on some of the paper and reduce the practicality of the device. Therefore, a winding device with fixed-position cutting is proposed to address the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: A fixed-position cutting winding device of this utility model includes a storage box. A thread pull assembly is provided inside the storage box. A pull plate is fixedly connected to the outside of the thread pull assembly. An upper rotating wheel is rotatably connected to the inside of the pull plate. A lower rotating wheel is rotatably connected to the inside of the storage box. A front-end printing press operating speed detection device is provided inside the storage box. A winding device is provided outside the storage box. A winding device operating speed detection device is provided inside the winding device. A counting sensor is provided inside the winding device. A front paper pressing mechanism is provided inside the winding device. A rear paper pressing mechanism is provided inside the winding device. A winding shaft pressure roller assembly is provided inside the winding device. The front and rear paper pressing mechanisms are both used in conjunction with the winding shaft pressure roller assembly. A winding shaft assembly is provided inside the winding device. A take-up roller is provided on the outside of the take-up shaft assembly. There are two take-up rollers. The take-up shaft pressure roller assembly works in conjunction with the take-up rollers. A cutting assembly is provided on the inside of the take-up device. This step involves setting up a roller lifting assembly, a front paper pressing mechanism, a rear paper pressing mechanism, and a take-up shaft pressure roller assembly. After the take-up roller is fully wound with paper, the roller lifting assembly is activated. The roller lifting assembly slowly moves the upper roller away from the lower roller, allowing more paper to be stored between the upper and lower rollers. This allows the paper to continue to be fed while preventing it from moving forward. Then, the front paper pressing mechanism, the rear paper pressing mechanism, and the take-up shaft pressure roller assembly are activated to press the paper down before cutting. This allows the components inside the storage box to continue feeding while the paper inside the take-up device can be fixed and then cut. This not only prevents the paper from stopping feeding but also allows for accurate cutting at the correct position, improving the stability of the device.

[0006] Preferably, a first soft pad is provided on the outside of the front paper pressing mechanism, and a second soft pad is provided on the rear paper pressing mechanism. By providing the first and second soft pads, when the front and rear paper pressing mechanisms clamp the paper, the first and second soft pads can separate the front and rear paper pressing mechanisms from the paper, so that they do not directly contact the paper, thereby preventing the paper from being damaged due to fixing and improving the stability of the device.

[0007] Preferably, sliders are fixedly connected to the outer sides of both the first and second soft pads, and fixing screws are threadedly connected to the inner sides of the front and rear paper pressing mechanisms. The fixing screws are threadedly connected to the sliders. This step, by setting sliders and fixing screws, allows the first and second soft pads to be unscrewed from the sliders through the fixing screws after long-term use, thereby facilitating the replacement of the first and second soft pads and improving the convenience of using the device.

[0008] Preferably, a guide block is fixedly connected to the inner side of the winding device, and a guide rod is slidably connected to the inner side of the guide block. Both the front paper pressing mechanism and the rear paper pressing mechanism are fixedly connected to the guide rod. This step, by setting the guide block and the guide rod, further restricts the range of motion of the front paper pressing mechanism and the rear paper pressing mechanism by limiting the guide rod with the guide block, making their movement more stable and improving the stability of the device.

[0009] Preferably, the winding device has a rotating groove on its inner side, and a limiting plate is rotatably connected to the inner side of the rotating groove. The limiting plate and the winding shaft assembly are fixedly connected. This step, by setting the limiting plate and the rotating groove, makes the connection between the winding shaft assembly and the winding device more stable and improves the stability of the device operation.

[0010] Preferably, a fixing rod is fixedly connected to the outside of the winding device. The fixing rod works in conjunction with the winding roller. By setting the fixing rod, after the winding roller is fully wound with paper, it can be moved to align with the fixing rod, and then the paper can be pulled off the winding roller. The winding roller can then be moved away from the fixing rod, making it easier to remove the paper from the fixing rod. This makes the unloading of the device more efficient and improves the convenience of using the device.

[0011] The advantages of this utility model are:

[0012] 1. This utility model, by setting up a thread puller assembly, a front paper pressing mechanism, a rear paper pressing mechanism, and a take-up shaft pressure roller assembly, after the outer side of the take-up roller is full of paper, activates the thread puller assembly. The thread puller assembly slowly drives the upper roller to move away from the lower roller, so that more paper can be stored between the upper and lower rollers. This allows the paper to continue to be conveyed without moving forward. Then, the front paper pressing mechanism, the rear paper pressing mechanism, and the take-up shaft pressure roller assembly are activated to press the paper down, and then it can be cut. This allows the components inside the storage box to continue conveying, while the paper inside the take-up device can be fixed and then cut. This not only ensures that the paper does not stop conveying, but also allows for accurate cutting of the paper at the correct position, improving the stability of the device.

[0013] 2. By setting a first soft pad and a second soft pad, when the front paper pressing mechanism and the rear paper pressing mechanism clamp the paper, the first soft pad and the second soft pad can separate the front paper pressing mechanism and the rear paper pressing mechanism from the paper, so that they will not directly contact the paper, thereby preventing the paper from being damaged due to fixing, and improving the stability of the device.

[0021] 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 scope of protection of the present utility model.

[0022] Specific implementation examples are given below.

[0023] Please see Figure 1-5As shown, a fixed-position cutting winding device includes a storage box 1. A thread puller assembly 2 is disposed inside the storage box 1. A pull plate 3 is fixedly connected to the outside of the thread puller assembly 2. An upper rotating wheel 4 is rotatably connected to the inside of the pull plate 3. A lower rotating wheel 5 is rotatably connected to the inside of the storage box 1. A front-end printing press operating speed detection device 6 is disposed inside the storage box 1. A winding device 7 is disposed outside the storage box 1. A winding device operating speed detection device 8 is disposed inside the winding device 7. A counting sensor 9 is disposed inside the winding device 7. A front paper pressing mechanism 10 is disposed inside the winding device 7. A rear paper pressing mechanism 11 is disposed inside the winding device 7. A winding shaft pressure roller assembly 12 is disposed inside the winding device 7. Both the front paper pressing mechanism 10 and the rear paper pressing mechanism 11 cooperate with the winding shaft pressure roller assembly 12. A winding shaft assembly 13 is disposed inside the winding device 7. A winding shaft pressure roller assembly 14 is disposed outside the winding shaft assembly 13. The winding roller 14 consists of two rollers, and the winding shaft pressure roller assembly 12 works in conjunction with the winding roller 14. A cutting assembly 15 is provided inside the winding device 7. This step involves setting up a thread puller assembly 2, a front paper pressing mechanism 10, a rear paper pressing mechanism 11, and a winding shaft pressure roller assembly 12. After the outer side of the winding roller 14 is fully wound with paper, the thread puller assembly 2 is activated. The thread puller assembly 2 slowly moves the upper roller 4 away from the lower roller 5, allowing more paper to be stored between the upper roller 4 and the lower roller 5. This ensures that the paper continues to be conveyed without moving forward. Then, the front paper pressing mechanism 10, the rear paper pressing mechanism 11, and the winding shaft pressure roller assembly 12 are activated to press the paper down, allowing for cutting. This achieves continuous conveying of the components inside the storage box 1, while the paper inside the winding device 7 is fixed and then cut. This not only prevents the paper from stopping but also allows for accurate cutting, improving the stability of the device.

[0024] Furthermore, such as Figure 3 and Figure 4 As shown, a first soft pad 16 is provided on the outside of the front paper pressing mechanism 10, and a second soft pad 17 is provided on the rear paper pressing mechanism 11. By providing the first soft pad 16 and the second soft pad 17, when the front paper pressing mechanism 10 and the rear paper pressing mechanism 11 clamp the paper, the first soft pad 16 and the second soft pad 17 can separate the front paper pressing mechanism 10 and the rear paper pressing mechanism 11 from the paper, so that they will not directly contact the paper, thereby preventing the paper from being damaged due to fixing, and improving the stability of the device.

[0025] Furthermore, such as Figure 4 and Figure 5As shown, sliders 18 are fixedly connected to the outer sides of the first soft pad 16 and the second soft pad 17. The inner sides of the front paper pressing mechanism 10 and the rear paper pressing mechanism 11 are threaded with fixing screws 19. The fixing screws 19 and the sliders 18 are threadedly connected. By setting the sliders 18 and fixing screws 19, the first soft pad 16 and the second soft pad 17 can be unscrewed from the sliders 18 by fixing screws 19 after long-term use, which facilitates the replacement of the first soft pad 16 and the second soft pad 17 and improves the convenience of using the device.

[0026] Furthermore, such as Figure 4 and Figure 3 As shown, a guide block 20 is fixedly connected to the inner side of the winding device 7, and a guide rod 21 is slidably connected to the inner side of the guide block 20. The front paper pressing mechanism 10 and the rear paper pressing mechanism 11 are both fixedly connected to the guide rod 21. This step, by setting the guide block 20 and the guide rod 21, restricts the range of motion of the front paper pressing mechanism 10 and the rear paper pressing mechanism 11 by restricting the guide rod 21 with the guide block 20, making their movement more stable and improving the stability of the device.

[0027] Furthermore, such as Figure 2 As shown, a rotating groove 22 is provided on the inner side of the winding device 7, and a limiting plate 23 is rotatably connected to the inner side of the rotating groove 22. The limiting plate 23 and the winding shaft assembly 13 are fixedly connected. This step, by setting the limiting plate 23 and the rotating groove 22, makes the connection between the winding shaft assembly 13 and the winding device 7 more stable, and improves the stability of the device operation.

[0028] Furthermore, such as Figure 2 As shown, a fixing rod 24 is fixedly connected to the outside of the winding device 7. The fixing rod 24 works in conjunction with the winding roller 14. By setting the fixing rod 24, after the winding roller 14 is fully wound with paper, it can be moved to align with the fixing rod 24, and then the paper can be pulled off the winding roller 14. The winding roller 14 can then be moved away from the fixing rod 24, making it easier to remove the paper from the fixing rod 24. This makes the unloading of the device more efficient and improves the convenience of using the device.

[0029] Working principle: During conveying, paper is placed on the outside of the upper roller 4 and lower roller 5 and inside the winding device 7. The paper's movement speed and position are monitored by the front-end printing press speed detection device 6, the winding device speed detection device 8, and the counting sensor 9. After the outer side of the winding roller 14 is fully wound with paper, the thread pull assembly 2 is activated. The thread pull assembly 2 slowly moves the upper roller 4 away from the lower roller 5, allowing more paper to be stored between the upper roller 4 and lower roller 5, enabling the paper to continue to be conveyed. Meanwhile, the paper will not continue to move forward. Then, the front paper pressing mechanism 10, the rear paper pressing mechanism 11, and the take-up shaft pressure roller assembly 12 are activated to press and fix the paper. Then, the cutting assembly 15 is activated to cut the paper. Then, the take-up shaft assembly 13 is activated. The take-up shaft assembly 13 drives the fully wound take-up roller 14 to move to the alignment with the fixing rod 24. Then, the paper is pushed down. At the same time, the take-up shaft assembly 13 drives the other unwound take-up roller 14 to the take-up position. Then, the paper is put on the outside of it and wound up.
