Description

Technical Field

[0001] The utility model relates to the technical field of cloth conveying, in particular to a tensioning and adjusting device for cloth conveying. Background Art

[0002] During the fabric production process, the fabric needs to be conveyed through a conveyor device to ensure that the fabric can be stably delivered to each process. During the conveying process, the fabric is prone to slipping between the fabric and the conveyor rollers, causing the fabric to sag during conveying, making it unstable. Therefore, a tensioning adjustment device is used to tighten the fabric to ensure stable conveying.

[0003] After searching, a utility model patent with the authorization announcement number CN220299908U was found, which is a tensioning and adjusting device for fabric conveying. It belongs to the field of fabric conveying technology and includes a base plate and a side plate mounted on the base plate. The side plate is equipped with an electric telescopic rod. The output end of the electric telescopic rod is equipped with a limit plate. A connecting rod is mounted on the top of the base plate. A connecting plate is mounted on one side of the connecting rod. Connecting blocks are slidably mounted on the connecting rod and the side plate. Conveying rollers are rotatably mounted on the side plate, the connecting block and the connecting plate. The two connecting blocks are connected by a first connecting frame, and a second connecting frame is mounted on the side plate. The utility model rotates the threaded rod, thereby driving the first connecting frame to move, thereby adjusting the position of the conveying roller, thereby tensioning the fabric. By setting an electric telescopic rod, the electric telescopic rod is activated to drive the limit plate to move, thereby adjusting the distance between the limit plate and the side plate, thereby enabling the limit plate to limit fabrics of different sizes, thereby preventing the fabric from shifting on the tensioning device.

[0004] However, the limiting plate of the device only limits passively and cannot actively flatten the edge of the fabric or eliminate local slack. Therefore, elastic or thin fabrics may still have curling and wrinkling problems during transportation due to edge friction, inertia or airflow. In view of this, the present application proposes a tensioning adjustment device for fabric transportation based on the above technical problems. Utility Model Content

[0016] Furthermore, a ground rod is fixedly installed at the bottom end of the chassis, and a self-locking wheel is fixedly installed at the bottom end of the ground rod.

[0017] The beneficial effects of the utility model are:

[0018] 1. The utility model provides a belt conveyor and an anti-curling component. When the fabric body is conveyed between the belt conveyor and the tensioning belt, the friction between the two sets of belt conveyors with opposite conveying directions and the tensioning belt applies lateral tension to the fabric body, thereby avoiding curling and wrinkling problems when the fabric body is conveyed. The anti-slip protrusions on the surface of the tensioning belt can enhance the friction force, so that the fabric remains flat during the conveying process.

[0019] 2. The utility model is provided with a depilatory component. When the cloth body is conveyed, one end of the cloth body is first passed through the active brush roller and the driven brush roller, then passes through the tensioning belt and the belt conveyor, and then passes around the conveying roller and the tensioning roller surface in turn. The cloth body is first depilated, and the motor is started. The motor drives the active wheel to rotate, and the active brush roller is driven by the synchronous belt to rotate. The driven brush roller is driven by the friction of the active brush roller to make a movement opposite to the rotation of the active brush roller, thereby depilating the cloth body. The depilatory direction is opposite to the conveying direction of the cloth body, and the cloth surface is scraped in an "antagonistic" manner, thereby enhancing the fiber stripping force and more thoroughly removing the hairiness or fluffy fibers.

[0020] 3. The utility model is provided with a spring, a handwheel and a driven brush roller. The driven brush roller can adapt to the thickness changes of different fabric bodies by using the elastic deformation of the spring. The design of the spring enables the driven brush roller to have a certain floating ability. When the thickness of the fabric body changes, the driven brush roller can automatically adjust the contact pressure between the fabric body to ensure that the bristles and the fabric body always maintain proper contact, thereby improving the hair removal efficiency and hair removal quality. By turning the handwheel, the handwheel drives the threaded rod to rotate, thereby realizing the downward movement of the upper pressure cover, and finally changing the compression degree of the spring to adjust the pressure of the driven brush roller on the fabric body, and at the same time, the floating degree of the driven brush roller can also be changed.

[0021] 4. The utility model provides an adjustment component, which drives the lifting block upward through the cylinder to increase the height of the tensioning roller, thereby adjusting the tension of the fabric body. The telescopic stroke of the cylinder can be accurately adjusted by the proportional valve, making the height adjustment of the tensioning roller more flexible and accurate. In addition, when the lifting block moves, it drives the second slider to slide in the second slide groove. The second slide groove ensures the stable movement of the lifting block in the vertical direction, avoids deviation or shaking, thereby ensuring that the tensioning roller can be raised and lowered smoothly and maintain the stability of the tension of the fabric body.

[0035] When the fabric body 7 is conveyed between the belt conveyor 3 and the tensioning belt 5, the friction between the two sets of belt conveyors 3 and the tensioning belt 5, which are conveying in opposite directions, applies lateral tension to the fabric body 7, thereby preventing the fabric body 7 from curling or wrinkling during conveyance.

[0042] Reference Figure 7Specifically, the L-shaped rod 12 includes a first straight portion 30 and a second straight portion 31 , and a conveying roller 32 is rotatably installed between the first straight portion 30 , between the second straight portion 31 , and between the chassis 1 .

[0043] Reference Figure 7-9 Specifically, the adjustment assembly includes a tensioning roller 33 arranged above the L-shaped rod 12, a fixing frame 34 is fixedly installed on the upper surface of the L-shaped rod 12, a lifting block 35 is provided inside the fixing frame 34, the tensioning roller 33 is rotatably installed between the lifting blocks 35, and second sliding grooves 36 are provided on the left and right inner walls of the fixing frame 34, a second slider 37 is slidably installed in the second sliding groove 36, and the second slider 37 is fixedly connected to the lifting block 35, and a cylinder 38 is fixedly installed on the upper surface of the fixing frame 34, and the output end of the cylinder 38 is fixedly connected to the lifting block 35;

[0044] The cylinder 38 drives the lifting block 35 upward to move, thereby increasing the height of the tensioning roller 33, thereby adjusting the tension of the fabric body 7. The telescopic stroke of the cylinder 38 can be precisely adjusted by the proportional valve, making the height adjustment of the tensioning roller 33 more flexible and accurate. In addition, when the lifting block 35 moves, it drives the second slider 37 to slide in the second slide groove 36.

[0045] The driven brush roller 16 can adapt to the thickness changes of different fabric bodies 7 by utilizing the elastic deformation of the spring 29. The design of the spring 29 enables the driven brush roller 16 to have a certain floating ability. When the thickness of the fabric body 7 changes, the driven brush roller 16 can automatically adjust the contact pressure between the fabric body 7 to ensure that the bristles and the fabric body 7 always maintain proper contact, thereby improving the hair removal efficiency and hair removal quality. By turning the handwheel 41, the handwheel 41 drives the threaded rod 27 to rotate, thereby realizing the downward movement of the upper pressure cover 28, and finally changing the compression degree of the spring 29 to adjust the pressure of the driven brush roller 16 on the fabric body 7, and at the same time, the floating degree of the driven brush roller 16 can also be changed.

[0046] Reference Figure 2 Specifically: a ground rod 39 is fixedly installed at the bottom end of the chassis 1, and a self-locking wheel 40 is fixedly installed at the bottom end of the ground rod 39.

[0047] Working Principle: When the fabric body 7 is conveyed between the belt conveyor 3 and the tensioning belt 5, the friction between the two sets of belt conveyors 3 and the tensioning belt 5, which are conveying in opposite directions, applies lateral tension to the fabric body 7, thereby preventing curling and wrinkling of the fabric body 7 during conveyance. The anti-slip protrusions 6 on the surface of the tensioning belt 5 can enhance the friction force, so that the fabric remains flat during the conveyance process.

[0048] When the fabric body 7 is conveyed, one end of the fabric body 7 is first passed between the active brush roller 15 and the driven brush roller 16, then passes between the tensioning belt 5 and the belt conveyor 3, and then passes around the surface of the conveying roller 32 and the tensioning roller 33 in turn. The fabric body 7 first performs hair removal work, and the motor 18 is started. The motor 18 drives the active wheel 19 to rotate, and drives the active brush roller 15 to rotate under the transmission of the synchronous belt 21. The driven brush roller 16 is driven by the friction of the active brush roller 15 to make a movement opposite to the rotation of the active brush roller 15, thereby removing hair from the fabric body 7. The direction of hair removal is opposite to the direction of conveyance of the fabric body 7, scraping the fabric surface in an "antagonistic" manner, enhancing the fiber stripping force, and more thoroughly removing hairiness or fluffy fibers;

[0049] The driven brush roller 16 can adapt to the thickness changes of different cloth bodies 7 by utilizing the elastic deformation of the spring 29. The design of the spring 29 enables the driven brush roller 16 to have a certain floating ability. When the thickness of the cloth body 7 changes, the driven brush roller 16 can automatically adjust the contact pressure between it and the cloth body 7 to ensure that the bristles and the cloth body 7 always maintain appropriate contact, thereby improving the hair removal efficiency and hair removal quality. By turning the handwheel 41, the handwheel 41 drives the threaded rod 27 to rotate, thereby realizing the downward movement of the upper pressure cover 28, and finally changing the compression degree of the spring 29 to adjust the pressure of the driven brush roller 16 on the cloth body 7, and at the same time, the floating degree of the driven brush roller 16 can also be changed;

[0050] The cylinder 38 drives the lifting block 35 upward to move, thereby increasing the height of the tensioning roller 33, and then adjusting the tension of the fabric body 7. The telescopic stroke of the cylinder 38 can be accurately adjusted by the proportional valve, making the height adjustment of the tensioning roller 33 more flexible and accurate. In addition, when the lifting block 35 moves, it drives the second slider 37 to slide in the second slide groove 36. The second slide groove 36 ensures the stable movement of the lifting block 35 in the vertical direction, avoiding deviation or shaking, thereby ensuring that the tensioning roller 33 can be lifted and lowered smoothly, maintaining the stability of the tension of the fabric body 7.
