Description

Technical Field

[0001] This utility model relates to the field of winding mechanisms, specifically a winding mechanism for paper production. Background Technology

[0002] Paper winding mechanisms are indispensable and crucial equipment in paper production lines. Their main function is to wind the produced paper into rolls according to specific specifications and tension requirements for subsequent packaging, transportation, and use. Traditional paper winding mechanisms typically include key components such as a frame, tension adjustment components, and take-up rollers. During the paper winding process, the tension adjustment components play a vital role, precisely controlling the paper tension based on factors such as the paper's material, thickness, and roll diameter to ensure the paper remains flat, tight, and orderly during winding.

[0003] Existing paper winding mechanisms also have the following drawbacks:

[0004] In traditional paper winding mechanisms, tension adjustment is typically achieved by manually rotating a screw using an adjustment knob. Specifically, the operator manually rotates the knob according to the paper's condition, adjusting the contact pressure and position between the tension roller and the paper via the screw's transmission action, thus regulating the paper tension. However, this manual adjustment method has several drawbacks and cannot meet the high-efficiency and precision requirements of modern paper production. First, manual adjustment cannot achieve precise tension control. Due to operator error and the limited transmission precision of the screw, the contact pressure and position between the tension roller and the paper cannot be precisely adjusted, making it impossible to maintain the tension within the set range. This not only affects the paper winding quality but may also lead to defects such as tearing, wrinkling, or curling during the winding process. Second, manual adjustment cannot ensure that the paper maintains constant tension during winding. During paper production, factors such as paper material, thickness, and roll diameter may change, requiring the tension adjustment component to quickly and accurately adjust the tension to adapt to these changes. However, manual adjustment requires operators to spend a lot of time and effort, and the adjustment accuracy cannot be controlled. Manual adjustment also causes the height of the tension roller to be inconsistent on both sides, resulting in uneven tension on both sides. This makes it impossible to keep the tension constant and fails to meet the needs of efficient and precise paper production. Utility Model Content

[0005] To overcome the shortcomings of existing technical solutions, this utility model provides a paper winding mechanism that effectively solves the technical problem that existing winding mechanisms rely on manual adjustment knobs to rotate screws and adjust the tension of tension rollers, which cannot achieve precise adjustment of paper tension, cannot keep the tension within the set range, and cannot ensure that the paper maintains a constant tension during the winding process.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a paper winding mechanism, including a frame, the frame being provided with a tension adjusting component for adjusting the tension of the paper and a detachable winding roller for winding the paper, the tension adjusting component including a U-shaped fixed mounting base and a conveying roller rotatably connected to the fixed mounting base, the bearings of the conveying roller passing through the fixed mounting base and extending to the outside of the fixed mounting base, two horizontally placed fixing rods fixedly provided on the side of the fixed mounting base, the edge of the fixed mounting base extending to form a sliding part, the sliding part extending along the length direction of the fixed mounting base, and both ends of the fixed mounting base being provided with a connection to the fixed mounting base. Two perpendicular fixed plates are provided, each with a detachable electric cylinder on its surface. A sliding part is provided with a fastening seat that moves along the length of the sliding part. A detachable tension roller is provided on the fastening seat, and the bearings of the tension roller pass through the fastening seat and extend to its exterior. The tension roller and the fastening seat are rotatably connected. The output end of the electric cylinder is connected to the fastening seat via a push rod. The surface of the fastening seat is concave and forms a groove extending along its length. The fastening seat is slidably connected to the sliding part via the groove. When adjusting the tension between the tension roller and the paper, the electric cylinder drives the push rod to move the fastening seat along the sliding part, thus adjusting the tension.

[0007] Furthermore, the two fixing rods are symmetrically arranged, and both fixing rods are on the same horizontal plane.

[0008] Furthermore, the frame is sequentially provided with a first transmission roller, a second transmission roller, and a third transmission roller, all of which are rotatably connected to the frame.

[0009] Furthermore, the side of the frame is provided with a positioning groove, and the take-up roller is detachably mounted in the positioning groove.

[0010] Furthermore, a latex layer is coated on the surface of both the conveying roller and the tension roller.

[0011] Furthermore, both the conveying roller and the tension roller are made of damping composite materials that can effectively absorb vibrations and noise generated during operation.

[0012] Furthermore, the frame is provided with a paper correction assembly to prevent paper deviation. The paper correction assembly is located below the take-up roller. The paper correction assembly includes two crossbars fixed to the frame and a rotatable anti-deviation roller. The two crossbars are symmetrically arranged. Each crossbar has two limiting plates, both of which move along the axial direction of the crossbar. An anti-deviation rod is fixedly provided at one end of each limiting plate. The anti-deviation roller is located on the anti-deviation rod and is rotatably connected to the anti-deviation rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides a paper production winding mechanism. By setting a fastening seat that can move along the sliding part and a tension roller connected thereto, as well as a push rod driven by an electric cylinder, it can achieve precise adjustment of paper tension. Compared with the traditional method of manually adjusting the tension roller by rotating a screw using a manual adjustment knob, by using the same electric cylinder to drive the push rod to move the fastening seat along the sliding part to adjust the tension roller, the tension can always be kept within the set range. This ensures that the paper maintains constant tension during the winding process, thereby ensuring smooth paper transmission and winding, and meeting the needs of efficient and precise production.

Detailed Implementation

[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 protection scope of the present utility model.

[0022] The following is combined Figures 1-5 A detailed description of this utility model is provided below:

[0023] A paper winding mechanism includes a frame 3. The frame 3 is equipped with a tension adjusting component 1 for adjusting the tension of the paper and a detachable winding roller 7 for winding the paper. The tension adjusting component 1 includes a U-shaped fixed mounting base 101 and a conveying roller 105 rotatably connected to the fixed mounting base 101. The bearings of the conveying roller 105 pass through the fixed mounting base 101 and extend to the outside of the fixed mounting base 101. Two horizontally placed fixing rods 102 are fixedly provided on the side of the fixed mounting base 101. The edge of the fixed mounting base 101 extends to form a sliding part 111, which extends along the length direction of the fixed mounting base 101. Two fixing plates 110 perpendicular to the fixed mounting base 101 are provided at both ends of the fixed mounting base 101. The surfaces of the fixing plates 110 are all provided with... The device includes a detachable electric cylinder 104. The sliding part 111 is provided with a fastening seat 107 that moves along the length of the sliding part 111. The fastening seat 107 is provided with a detachable tension roller 106. The bearings of the tension roller 106 all pass through the fastening seat 107 and extend to the outside of the fastening seat 107. The tension roller 106 and the fastening seat 107 are rotatably connected. The output end of the electric cylinder 104 is connected to the fastening seat 107 via a push rod 109. The surface of the fastening seat 107 is recessed inward and forms a groove 108 that extends along the length of the fastening seat 107. The fastening seat 107 is slidably connected to the sliding part 111 via the groove 108. When adjusting the tension between the tension roller 106 and the paper, the electric cylinder 104 drives the push rod 109 to move the fastening seat 107 along the sliding part 111, thereby adjusting the tension.

[0024] The two fixing rods 102 are symmetrically arranged and are both on the same horizontal plane. By setting the two fixing rods 102, the paper can be guided to pass through the gap between the tension roller 106 and the conveying roller 105 in sequence.

[0025] The frame 3 is sequentially provided with a first transmission roller 4, a second transmission roller 5, and a third transmission roller 6. The first transmission roller 4, the second transmission roller 5, and the third transmission roller 6 are all rotatably connected to the frame 3 and are used to transport paper. They can guide the paper to be transported smoothly in the winding mechanism, ensuring the continuity and stability of the paper during the transport process.

[0026] The frame 3 has a positioning groove 8 on its side. The take-up roller 7 is detachably mounted in the positioning groove 8. The positioning groove 8 allows for easy replacement of take-up rollers 7 of different sizes, and facilitates the installation and removal of the take-up roller 7. The take-up roller 7 is connected to an external drive motor. When the paper is being wound up, the external drive motor drives the take-up roller 7 to rotate and wind up the paper.

[0027] The surfaces of both the conveyor roller 105 and the tension roller 106 are covered with a latex layer 103. The latex layer 103 has a certain elasticity, which helps to better control the tension of the paper. The latex layer 103 can also prevent the conveyor roller 105 and the tension roller 106 from directly contacting the paper, thereby reducing noise. Both the conveyor roller 105 and the tension roller 106 are made of damping composite materials that can effectively absorb the vibration and noise generated during operation, which can further reduce noise.

[0028] The frame 3 is equipped with a paper correction assembly 2 to prevent paper deviation. The paper correction assembly 2 is located below the take-up roller. The paper correction assembly 2 includes two crossbars 201 fixed to the frame 3 and a rotatable anti-deviation roller 204. The two crossbars 201 are symmetrically arranged. Each crossbar 201 has two limiting plates 202, which can move along the axial direction of the crossbars 201. An anti-deviation rod 203 is fixedly installed at one end of each limiting plate 202. The anti-deviation roller 204 is installed on the anti-deviation rod 203 and is rotatably connected to it. The position of the limiting plate 202 can be manually adjusted so that the anti-deviation roller 204 blocks both sides of the take-up roller 7, correcting the deviation of the paper during the winding process.

[0029] This embodiment of a paper production winding mechanism, by providing a fastening seat 107 movable along the sliding part 111 and a tension roller 106 connected thereto, and a push rod 109 driven by an electric cylinder 104, can achieve precise adjustment of paper tension. Compared with the traditional method of manually adjusting the tension roller 106 by rotating a screw using a manual adjustment knob, by using the same electric cylinder 104 to drive the push rod 109 to move the fastening seat 107 along the sliding part 111 to adjust the tension roller 106, the tension can always be kept within the set range. This ensures that the paper maintains a constant tension during the winding process, thereby ensuring smooth paper transmission and winding, and meeting the needs of efficient and precise production.

[0030] During paper winding, the paper is sequentially fed through the first drive roller 4, the second drive roller 5, the third drive roller 6, and the fixed rod 102, ensuring it passes smoothly through the gap between the conveyor roller 105 and the tension roller 106, and is wound onto the take-up roller 7. The take-up roller 7 is driven by an externally connected drive motor for winding. The preset tension value of the tension adjustment component 1 is adjusted according to parameters such as the paper's material, thickness, and roll diameter. The electric cylinder 104 drives the push rod 109 to adjust the contact pressure and position between the tension roller 106 and the paper. The tension roller 106 is adjusted by moving the fastening seat 107 along the sliding part 111, thereby achieving precise control of the paper tension. The electric cylinder 104 drives the fastening seat 107 to move via the push rod 109, according to the preset tension value. The electric cylinder 104 adjusts the position of the fastening seat 107 accordingly to ensure that the tension roller 106 applies a constant tension to the paper. During the winding process, the paper's transmission status and tension are continuously monitored. If the paper tension is found to be too high or too low, the position of the tension roller 106 is adjusted in time by the electric cylinder 104 to ensure that the tension is always kept within the set range. By adjusting the correction component 2, the two limit plates 202 move on the crossbar 201, adjusting the position of the anti-deviation roller 204 so that both anti-deviation rollers 204 are close to the sides of the take-up roller 7, so that the surface of the anti-deviation roller 204 contacts the side of the paper to prevent deviation. When the paper on the take-up roller 7 reaches the preset length or thickness, the winding mechanism stops working and completes the paper winding process.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
