A fabric feeder

Abstract

This utility model discloses a fabric feeding frame, which includes a guide roller. A braking device is installed at either end of the guide roller. The braking device includes a fixed plate, a cylinder, and a brake band. The fixed plate is horizontally mounted on a frame below the shaft end of the guide roller. The cylinder is fitted onto the shaft end of the guide roller. The brake band is wrapped around the upper surface of the cylinder and forms a wrap angle with the cylinder. One end of the brake band is fixed to the fixed plate by a fixing member, and the other end of the brake band is connected to a linear drive mechanism. The linear drive mechanism has a longitudinally arranged movement path. The fabric feeding frame implemented by this utility model can use the linear drive mechanism to drive the other end of the brake band to extend and retract, so that the brake band contacts or disengages from the cylinder, thereby controlling whether the guide roller rotates. It has the advantages of simple structure, convenient operation, and low cost.

Description

Technical Field

[0001] This utility model relates to the field of printing and dyeing machinery and equipment, and in particular to a fabric feeding frame. Background Technology

[0002] Fabric feeders are key auxiliary equipment used for fabric processing in industries such as textiles, dyeing, and garments. They consist of tension bars, fabric tensioners, edge suction devices, guide rollers, and frames. By fixing the fabric and guiding it to be transported in an orderly manner, they prevent the fabric from slipping, tangling, or being interrupted during the feeding process, ensuring that subsequent equipment (such as dyeing machines and cutting machines) can work continuously and improving production efficiency.

[0003] When the fabric enters the main machine from the feed rack, an edge-aligning machine is usually added to prevent the fabric from shifting left or right. The fabric needs a certain height difference to enter the edge-aligning machine from the guide rollers, allowing sufficient time for the machine to adjust for any deviation. This requires the guide rollers on the feed rack to be at a certain height. However, this inevitably creates a problem: due to the fabric's own weight and the rotation of the guide rollers, the fabric experiences acceleration during its descent, causing it to enter the edge-aligning machine too quickly. This results in the fabric piling up in front of the edge-aligning machine or even falling to the ground. The higher the fabric density and the greater the height, the more pronounced this phenomenon becomes.

[0004] Textile factories typically address this problem by adding a speed reducer to control the rotational speed of the guide rollers, or by directly wrapping the guide rollers with strips of fabric to prevent them from rotating, thereby controlling the linear speed of the fabric. While both methods achieve the desired result, the first method is too costly, and the second method requires workers to frequently climb up to operate it, which is both dangerous and cumbersome. Utility Model Content

[0005] The purpose of this utility model is to provide a fabric feeding frame.

[0006] The technical solution to achieve the purpose of this utility model is: a fabric feeding frame, which includes a guide roller and an edge-aligning machine. The guide roller is installed on a frame above the edge-aligning machine. A braking device is installed at any end of the guide roller. The braking device includes a fixing plate, a cylinder, and a brake band. The fixing plate is horizontally installed on the frame below the shaft end of the guide roller. The cylinder is fitted onto the shaft end of the guide roller. The brake band is wrapped around the upper surface of the cylinder and forms a wrap angle with the cylinder. One end of the brake band is fixed to the fixing plate by a fixing member. The other end of the brake band is connected to a linear drive mechanism. The movement path of the linear drive mechanism is arranged longitudinally.

[0007] Furthermore, a braking device is installed at each end of the guide roller.

[0008] Furthermore, the linear drive mechanism is a lifting cylinder, which is fixed on the frame. The piston rod of the lifting cylinder passes upward through the fixed plate, and a clamping plate is installed at the end of the piston rod. The other end of the brake band is fixedly connected to the clamping plate.

[0009] The fabric feeding frame of this invention utilizes a linear motion mechanism to extend and retract the other end of the brake band, causing the brake band to contact or disengage from the cylinder, thereby controlling whether the guide roller rotates. It has the advantages of simple structure, convenient operation, and low cost. Attached Figure Description

[0012] Figure 3 This is a schematic diagram of the braking device described in an embodiment of the present invention. Detailed Implementation

[0013] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0014] like Figure 1 and Figure 2 As shown, a fabric feeding frame includes a guide roller 1 and an edge-aligning machine 2. The guide roller 2 is mounted on a frame 10 above the edge-aligning machine 2. A braking device 3 is installed at either end of the guide roller 1. The braking device 3 includes a fixing plate 31, a cylinder 32, a brake band 33, and a lifting cylinder 34. The fixing plate 31 is horizontally mounted on the frame 10 below the shaft end 11 of the guide roller 2. The cylinder 32 is fitted onto the shaft end 11 of the guide roller 1 by a set screw. The brake band 33 is wound around the cylinder. The upper surface of 32 forms a wrap angle with the body of the cylinder 32. One end 331 of the brake band 33 is fixed to the fixing plate 31 by a fastener. The other end 332 of the brake band 33 is fixed to the lifting cylinder 34. The lifting cylinder 34 is fixed to the frame 10. The piston rod 341 of the lifting cylinder 34 passes upward through the fixing plate 32. A clamping plate 35 is installed at the end of the piston rod 341 of the lifting cylinder 34. The other end 332 of the brake band 33 is fixedly connected to the clamping plate 35.

[0015] During the fabric feeding process, when it is necessary to stop the guide roller 1 from rotating, the piston rod of the vertical cylinder can be controlled by the manual valve to retract, thereby tightening the brake band and making it contact the cylinder. The brake band and the cylinder generate a large frictional force, preventing the guide roller from rotating. When it is necessary to rotate the guide roller, the piston rod of the vertical cylinder can be controlled by the manual valve to extend, causing the brake band to disengage from the cylinder.

[0016] The braking device described in this utility model can also be two sets, installed on the two shaft ends of the guide roller, for better control effect.

[0017] The linear drive mechanism that drives the other end of the brake band to move up and down is not limited to the embodiment described. The other end of the brake band can also be fixed to a conventional linear drive mechanism in the mechanical field, such as a screw lifting mechanism.

[0018] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent process transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
