Description

Technical Field

[0001] This utility model belongs to the field of fabric take-up tension roller technology, specifically relating to fabric take-up tension roller. Background Technology

[0002] In the textile industry, tension rollers used for winding fabrics are a key device, mainly used to control and adjust the tension of the fabric during the winding process to ensure smooth winding and uniform tension, and to avoid problems such as slack, wrinkles or overstretching.

[0003] A domestic utility model patent application (CN202323059237.0) discloses a fabric roll winding mechanism for easy installation of a roll, comprising: a base for bearing and limiting; a winding roller that engages and passes through the center of the base; and a pressure plate disposed below and in front of the winding roller. It also includes: an adjusting rod disposed above the winding roller that engages and passes through the base, and motors connected to the left sides of both the winding roller and the adjusting rod via couplings; the pressure plate is rotatably connected to the upper surface of the front center of the base, and a movable plate nested and connected to the base is disposed below the pressure plate; and a limiting plate fixed to the upper right side of the base. This fabric roll winding mechanism facilitates the installation and disassembly of the roll body, limits the winding of the fabric roll outside the roll body, and facilitates the close contact and compression of the fabric roll during winding outside the roll body, resulting in good winding effect and easy cutting of the fabric roll for subsequent winding. In the process of winding the fabric, the increased thickness of the winding roller will also affect the tension of the fabric. The winding tension is essentially the difference in tension between the take-up roller and the unwinding end (or the previous process). It is used to overcome frictional resistance and inertial force and keep the material taut. As the winding diameter increases, the tension also gradually increases. Excessive tension can lead to fabric breakage. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a fabric take-up tension roller, including a roller base frame, two sets of side frames fixedly installed on the top of the roller base frame, a top frame fixedly installed on the top of the side frames, and a pressure roller and a take-up roller installed between the side frames. It also includes positioning plates fixedly installed on both sides of the top of the roller base frame. The take-up roller and the pressure roller are slidably installed at both ends with the side frames through auxiliary sliding mechanisms. The pressure roller has anti-compression mechanisms fixedly installed on the bottom of the top frame on both sides of its top. The take-up roller has sinking mechanisms fixedly installed on the positioning plates on both sides of its bottom. A drive mechanism for driving the take-up roller to rotate is installed at one end of the take-up roller.

[0005] As a further preferred technical solution of this utility model, multiple sets of triangular support frames for reinforcement are fixedly installed at the connection position of the top frame and the side frame, and an electrical control box is fixedly installed on the side frame on one side of the roller base frame.

[0006] The overall stability of the roller base frame, side frame, and top frame is increased by using a triangular support frame.

[0007] As a further preferred technical solution of this utility model, fixed bearings are fixedly installed at both ends of the pressing roller, a connecting plate is fixedly installed at one end of the fixed bearing, and a top slider is fixedly installed on the connecting plate.

[0008] By setting a fixed bearing, the pressure roller can rotate to assist in pressing the fabric, reducing friction between the fabric surface and the pressure roller.

[0009] As a further preferred technical solution of this utility model; the anti-compression mechanism includes an outer frame fixedly installed on two sets of triangular support frames, an anti-compression spring fixedly installed inside the outer frame, and a connecting column fixedly installed at the bottom of the anti-compression spring. A top limiting block is installed at the bottom of the connecting column, and the bottom of the top limiting block cooperates with the pressing roller to limit the movement.

[0010] During the process of pressing and flattening the bottom fabric by the pressure roller, the thickness of the fabric increases as it is wound up. The thickened fabric squeezes the bottom of the pressure roller, causing it to rise under the action of the top limit block. The pressure roller is then adjusted in position by the anti-compression spring, ensuring that the pressure roller flattens the fabric.

[0011] As a further preferred technical solution of this utility model; the auxiliary sliding mechanism includes a slide rail frame and an inclined slide frame respectively fixedly installed on the top and bottom of the inner side of the side frame. The slide rail frame and the top slider cooperate to slide together. A bottom slider is slidably installed on the inclined slide frame, and a docking plate is fixedly installed on the bottom slider. An extension bottom plate is fixedly installed on the docking plate. The two ends of the take-up roller are connected to the docking plate through connecting bearings.

[0012] The take-up roller slides on the inclined slide frame via a bottom slider. The inclined slide frame is set at an angle to facilitate the roller's downward sliding according to its weight during the winding process. Sliding downward at an angle makes it easier to adjust the tension on the take-up roller, reducing the risk of fabric breakage due to excessive tension.

[0013] As a further preferred technical solution of this utility model, the driving mechanism includes a driving motor fixedly installed on the top of the extension base plate, and a pulley set fixedly installed at the output end of the driving motor and at the corresponding position on the take-up roller. The output end of the driving motor is fixedly connected to the pulley set, and limit plates are fixedly installed at both ends of the take-up roller inside the pulley set.

[0014] The drive motor drives the pulley assembly to rotate, which in turn rotates the take-up roller to take up the fabric.

[0015] As a further preferred technical solution of this utility model; the settling mechanism includes a bottom frame fixedly installed on the top of the positioning plate, a shock-absorbing spring fixedly installed inside the bottom frame, and an extrusion column fixedly installed on the top of the shock-absorbing spring. The top of the extrusion column extends out of the bottom frame and is fixedly installed with a pressure plate. The top of the pressure plate is fixedly installed with a bottom limiting block that limits the bottom of the take-up roller.

[0016] The take-up roller is supported by a shock-absorbing spring. As the weight gradually increases during the winding process, the stability of the take-up roller is ensured by the sliding and sinking of the bottom slider on the inclined carriage. The take-up roller can move downward according to the weight, thereby reducing the impact of tension.

[0017] As a further preferred technical solution of this utility model, the bottom limiting block and the top limiting block are both fixedly installed with limiting ends on both sides. Two sets of mounting grooves are opened at the bottom position of the limiting end. Multiple sets of ball blocks are slidably installed in the mounting grooves, and smooth curved surfaces are provided between the ball blocks.

[0018] By using ball bearings to cooperate with the take-up roller and the pressure roller respectively, the rotation of the take-up roller and the pressure roller is not affected. Beneficial effects

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. The take-up roller slides on the inclined slide frame via a bottom slider. The inclined slide frame is set at an angle to facilitate the downward sliding of the take-up roller according to the weight on the take-up roller during the winding process. Sliding downward at an angle makes it easier to adjust the tension on the take-up roller and reduce the risk of fabric breakage due to excessive tension.

[0021] 2. During the process of pressing and flattening the bottom fabric by the pressure roller, the thickness of the fabric increases as it is wound up. The thickened fabric squeezes the bottom of the pressure roller, causing it to rise under the action of the top limit block. The pressure roller is then adjusted in position by the anti-compression spring, ensuring that the pressure roller flattens the fabric. Attached Figure Description

Detailed Implementation

[0027] This specific embodiment is a fabric take-up tension roller.

[0028] In the process of winding the fabric, the thickness of the winding roller increases, which also affects the tension of the fabric. The winding tension is essentially the difference in tension between the take-up roller and the unwinding end (or the previous process). It is used to overcome frictional resistance and inertial force and keep the material taut. As the winding diameter increases, the tension also gradually increases. Excessive tension can lead to fabric breakage.

[0029] Example 1: Its structural schematic diagram is as follows Figures 1-4As shown. The fabric take-up tension roller includes a roller base frame 1, two sets of side frames 13 fixedly installed on the top of the roller base frame 1, and a top frame 11 fixedly installed on the top of the side frames 13. Multiple sets of triangular support frames 12 for reinforcement are fixedly installed at the connection point between the top frame 11 and the side frames 13. An electrical control box 2 is fixedly installed on one side of the side frame 13 of the roller base frame 1. The triangular support frames 12 increase the overall stability of the roller base frame 1, side frames 13, and top frame 11. It also includes a pressure roller 4 and a take-up roller 3 installed between the side frames 13, and positioning plates 14 fixedly installed on both sides of the top of the roller base frame 1. The take-up roller 3 and the pressure roller 4 are slidably installed at both ends to the side frames 13 via auxiliary sliding mechanisms 6. The pressure roller 4 has anti-compression mechanisms 5 fixedly installed on both sides of its top, which are fixed to the bottom of the top frame 11.

[0030] Fixed bearings 41 are fixedly installed at both ends of the pressure roller 4. A connecting plate 42 is fixedly installed at one end of the fixed bearing 41, and a top slider 43 is fixedly installed on the connecting plate 42. The fixed bearings 41 facilitate the rotation of the pressure roller 4 when pressing the fabric, reducing friction between the fabric surface and the pressure roller 4. The anti-compression mechanism 5 includes an outer frame 51 fixedly installed on two sets of triangular support frames 12. An anti-compression spring 54 is fixedly installed inside the outer frame 51, and a connecting column 52 is fixedly installed at the bottom of the anti-compression spring 54. A top limiting block 53 is installed at the bottom of the connecting column 52, and the bottom of the top limiting block 53 cooperates with the pressure roller 4 to limit its position. During the process of the pressure roller 4 pressing and flattening the bottom fabric, the thickness of the fabric increases with winding. The thickened fabric squeezes the bottom of the pressure roller 4, causing it to rise under the action of the top limiting block 53. The anti-compression spring 54 adjusts the position of the pressure roller 4 to ensure that the pressure roller 4 flattens the fabric.

[0031] The take-up roller 3 has sinking mechanisms 7 fixedly installed on both sides of its bottom, which are fixedly mounted to the positioning plate 14. The auxiliary sliding mechanism 6 includes a slide rail 61 and an inclined slide 62 fixedly installed on the top and bottom of the inner side of the side frame 13, respectively. The slide rail 61 slides in cooperation with the top slider 43. The bottom slider 63 is slidably mounted on the inclined slide 62, and a docking plate 631 is fixedly mounted on the bottom slider 63. An extension bottom plate 632 is fixedly mounted on the docking plate 631. The two ends of the take-up roller 3 are connected to the docking plate 631 through connecting bearings 32. The take-up roller 3 slides on the inclined slide 62 via the bottom slider 63. The inclined slide 62 is inclined to facilitate sinking and sliding according to the weight on the take-up roller 3 during the winding process. Sliding downwards at an angle facilitates the adjustment of the tension on the take-up roller 3, reducing the risk of fabric breakage due to excessive tension. A drive mechanism 8 for driving the take-up roller 3 to rotate is installed at one end of the take-up roller 3. The drive mechanism 8 is controlled by the electrical control box 2 to achieve the winding of the fabric. The drive mechanism 8 includes a drive motor 81 fixedly mounted on the top of the extension base plate 632. Pulley sets 82 are fixedly mounted at corresponding positions on the output end of the drive motor 81 and the take-up roller 3. The output end of the drive motor 81 is fixedly connected to the pulley sets 82. Limiting plates 31 are fixedly mounted on both ends of the take-up roller 3 inside the pulley sets 82. The drive motor 81 drives the pulley sets 82 to rotate, causing the take-up roller 3 to rotate and wind up the fabric. The settling mechanism 7 includes a base frame 72 fixedly mounted on the top of the positioning plate 14, a shock-absorbing spring 74 fixedly mounted inside the base frame 72, and a pressing column 73 fixedly mounted on the top of the shock-absorbing spring 74. A pressure plate 71 is fixedly mounted on the top of the pressing column 73 extending out of the base frame 72. A bottom limiting block 75, which limits the bottom of the take-up roller 3, is fixedly mounted on the top of the pressure plate 71. The take-up roller 3 is supported by a shock-absorbing spring 74. As its weight gradually increases during winding, the stability of the take-up roller 3 is ensured by the sliding and sinking of the bottom slider 63 on the inclined slide 62. The take-up roller 3 can move downwards according to its weight, thereby reducing the impact of tension. Limiting ends 531 are fixedly installed on both sides of the top of the bottom limiting block 75 and the top limiting block 53. Two sets of mounting grooves 532 are provided at the bottom of the limiting ends 531. Multiple sets of ball bearing blocks 533 are slidably installed in the mounting grooves 532, and smooth curved surfaces 534 are provided between the ball bearing blocks 533. The ball bearing blocks 533 cooperate with the take-up roller 3 and the pressure roller 4 respectively, without affecting the rotation of the take-up roller 3 and the pressure roller 4.

[0032] The drive motor 81 drives the pulley assembly 82 to rotate, causing the take-up roller 3 to rotate and take up the fabric. During the take-up process, the take-up roller 3 is supported by the shock-absorbing spring 74. As the weight gradually increases during the take-up process, the bottom slider 63 on the inclined slide 62 slides down to ensure the stability of the take-up roller 3. The take-up roller 3 can move downward according to the weight. During the take-up process, the pressure roller 4 presses and flattens the bottom fabric of the take-up roller 3. As the thickness of the fabric increases with the take-up, the thicker fabric squeezes the bottom of the pressure roller 4, causing it to rise under the action of the top limit block 53. The pressure spring 54 adjusts the rising position of the pressure roller 4 to ensure that the pressure roller 4 flattens the fabric.

[0033] All technical features in this embodiment can be freely combined according to actual needs.

[0034] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
