A high-speed, simple fabric storage structure

Abstract

This utility model discloses a high-speed, simplified fabric storage structure, including a fabric storage frame. A second guide roller is positioned at the bottom center, with two guide rollers symmetrically positioned on either side. Two sets of vertically sliding floating traction rollers are symmetrically arranged at the top, each equipped with a drive mechanism to control its lifting and lowering. The symmetrical double-floating roller layout forms a symmetrical "M"-shaped fabric path structure centered on the second guide roller, ensuring that the movement trajectories and forces of the two sets of traction rollers are mirror-symmetrical. Under the same stroke, the fabric storage length of the double-roller structure is twice that of the traditional single-roller structure, and four times that of the four-roller symmetrical layout. The floating traction rollers are driven by the midpoint of the connecting block, automatically offsetting the off-center load torque, reducing fabric tension fluctuations, maintaining the original control system parameters, and improving performance only through mechanical symmetrical expansion. No re-adjustment of electrical components is required, significantly reducing modification costs.

Description

Technical Field

[0001] This utility model relates to the field of tape production technology, and in particular to a high-speed, simple fabric storage structure. Background Technology

[0002] In the tape production process, the raw fabric is processed in roll form through an adhesive coating process. During production, the raw fabric rolls need to be automatically spliced ​​together using the tape at the unloading point, but this splicing operation causes a brief pause in the unloading machine. To ensure the continuity of subsequent production, a fabric storage mechanism needs to be installed after unloading. Its working principle is as follows:

[0003] During normal operation, the fabric storage mechanism adjusts the speed of the fabric pulling motor in the unwinding section using a resistance ruler, so that the original fabric is gradually accumulated in the fabric storage machine. When receiving the fabric, the fabric pulling motor stops running, and the fabric storage machine releases the pre-stored original fabric to maintain the subsequent production until the unwinding section completes the receiving of the fabric. Then the fabric pulling motor restarts, and the fabric storage machine is filled with original fabric again.

[0004] Currently, the fabric storage capacity of the fabric storage mechanism is relatively small, only able to meet the fabric feeding needs during low-speed production (below a certain speed), without requiring subsequent machine shutdown. However, as production speeds increase to higher levels, the existing fabric storage capacity is insufficient, resulting in the inability to fully cover downtime during fabric feeding, thus affecting production efficiency. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] To address the aforementioned problems, this utility model provides the following technical solution:

[0007] A high-speed, simple fabric storage structure includes a fabric storage frame. A second guide roller is provided in the middle of the fabric storage frame near the bottom. A first guide roller is provided at the bottom of the fabric storage frame with the second guide roller as the center of symmetry. Two sets of vertically sliding floating traction rollers are symmetrically arranged near the top area of ​​the fabric storage frame. Each floating traction roller is equipped with a drive mechanism to control the traction roller to move up and down in the vertical direction.

[0008] Preferably, the guide roller one, guide roller two, and floating traction roller are completely identical.

[0009] Preferably, the floating traction roller is provided with embedded blocks at both ends, and the embedded blocks slide between rod one and rod two on the side of the fabric storage frame.

[0010] Preferably, the drive structure includes a cylinder, a cylinder shaft, and a connecting block, with the cylinder mounted on rod two on the side of the fabric storage frame.

[0011] Preferably, the cylinder shaft of the cylinder is provided with a connecting block, the connecting block is connected to the outer surface of the embedded block, and the cylinder shaft is connected to the middle of the connecting block.

[0012] The beneficial effects of this utility model are as follows: It adopts a symmetrical double floating roller layout, with the second guide roller as the central axis, forming a completely symmetrical "M" shaped fabric path structure within the fabric storage frame. This makes the motion trajectory and force distribution of the two sets of floating traction rollers mirror symmetrical. Under the same stroke, the effective fabric storage length of the symmetrical double roller structure is twice that of the traditional single roller structure, and the four-roller symmetrical layout can reach four times. The symmetrically distributed floating traction rollers are driven by the midpoint of the connecting block, which automatically offsets the off-center load torque, reduces the fluctuation of fabric tension, and maintains the original control system parameters. Performance improvement is achieved only through mechanical symmetrical expansion, without the need to readjust electrical components such as resistance rulers, thereby significantly reducing the transformation cost.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0024] Example 1

[0025] Reference Figures 1 to 5 This embodiment of the present invention provides a high-speed, simple fabric storage structure, including a fabric storage frame 100. A second guide roller 104 is provided in the middle of the fabric storage frame 100 near the bottom. A first guide roller 103 is provided at the bottom of the fabric storage frame 100 with the second guide roller 104 as the center of symmetry. Two sets of vertically sliding floating traction rollers 105 are symmetrically arranged near the top area of ​​the fabric storage frame 100. Each floating traction roller 105 is equipped with a drive mechanism 200 for controlling the traction roller 105 to move up and down in the vertical direction.

[0026] Specifically, in the fabric storage structure, the guide rollers and floating traction rollers 105 are arranged symmetrically around guide roller 104, with guide roller 104 installed in the middle of the fabric storage frame 100 near the bottom. Therefore, the adhesive tape 300 is arranged in an "M" shape in this simple fabric storage structure. In contrast, existing simple fabric storage structures, which only have one floating traction roller 105, have the adhesive tape arranged in a "V" shape under the same fabric storage frame 100.

[0027] Assuming the existing simple fabric storage structure is type A, this embodiment is type B. If type A needs to store 5 meters of fabric, its floating traction roller needs to move upward by 2 meters; while type B can achieve the same 5-meter fabric storage capacity with the floating traction roller only moving upward by 1 meter. This means that, without changing the resistance ruler control, type B's fabric storage capacity is twice that of type A, while the moving distance of the floating traction roller is halved.

[0028] By analogy, if a set of floating traction rollers 105 is added to the A-type structure and arranged symmetrically with guide roller 104 as the center (called the C-type structure), the fabric storage capacity of the C-type structure can reach 4 times that of the A-type structure.

[0029] To further explain, as a high-speed and simple fabric storage structure, the method of setting guide rollers 103 with guide roller 2 104 as the center of symmetry and symmetrically setting an even number of vertically sliding floating traction rollers 105 near the top area of ​​the fabric storage frame 100 is simple and feasible. It does not require a series of pre-test work such as readjusting the resistance ruler. The fabric storage data of the improved fabric storage structure can be obtained by using the existing (Type A) parameters, namely the ratio of the upward movement distance of the floating traction roller to the upward movement distance of the existing floating traction roller.

[0030] In summary, the traditional single floating roller "V" shaped structure (as described in the background art) can only maintain the fabric storage capacity for low-speed fabric splicing during high-speed production. When the production line speed increases to over 150m / min, the fabric release time during fabric splicing shutdowns is insufficient, forcing subsequent processes to stop simultaneously. If the fabric storage capacity is increased by increasing the frame height, the resistance ruler control system needs to be modified simultaneously, involving complex debugging such as resetting electrical parameters and reorganizing the mechanical structure.

[0031] The system adopts a mirror layout with guide roller 104 as the symmetrical center: fixed guide roller 103 (symmetrically distributed) + guide roller 104 (central axis) are set at the bottom, and double floating traction rollers 105 are configured at the top.

[0032] The adhesive tape path forms an "M" shape, achieving a geometric expansion compared to the traditional "V" shaped path;

[0033] Type B structure (double floating rollers): Under the same floating roller stroke, the fabric storage capacity = 2 × Type A;

[0034] C-type structure (four floating rollers): Fabric storage capacity = 4 × A-type (not shown in the example, but the principle is the same);

[0035] This structure achieves a geometric increase in fabric storage capacity through simple mechanical symmetry expansion without altering the control system, making it particularly suitable for low-cost retrofitting of existing high-speed production lines. Compared to traditional solutions that increase frame height, the retrofit cycle is significantly shortened, while the cost is still lower than traditional solutions.

[0036] Furthermore, the guide roller 103, guide roller 2 104 and floating traction roller 105 are completely identical, and the error in fabric storage can be reduced by using the same roller shaft;

[0037] The fabric storage structure uses a cylinder as the traction power source for the floating traction roller 105, just like common fabric storage structures. Specifically, the floating traction roller 105 has embedded blocks 105a at both ends. The embedded blocks 105a slide between rod 101 and rod 202 on the side of the fabric storage frame 100, which serves to limit the floating traction roller 105.

[0038] The drive structure 200 includes a cylinder 201, a cylinder shaft 202, and a connecting block 203. The cylinder 201 is mounted on the second rod 102 on the side of the fabric storage frame 100. The connecting block 203 is mounted on the cylinder shaft 202 of the cylinder 201. The connecting block 203 is connected to the outer surface of the embedded block 105a, and the cylinder shaft 202 is connected to the middle of the connecting block 203. This reduces the use of cylinders on the single-sided floating traction roller 105.
