Description

Technical Field

[0001] The utility model relates to the technical field of fabric production, and particularly relates to a weft-jet loom cloth edge tension control device. Background Art

[0002] When producing chemical fiber filament products, both the warp and weft filaments have relatively large tensions. After the fabric is woven, the raw materials shrink, resulting in the width of the fabric being less than that of the warp filaments. The warp filaments on both sides contract inward at the weaving opening. The two sides of the fabric are supported by the temple, waste edge filaments, and weft filament tension. The continuously changing shedding causes the warp filaments to move up and down continuously, resulting in plastic deformation of the warp filaments and causing the warp filaments at the cloth edge to become loose. During the fabric production process, a cloth edge tension control device is generally used to control the cloth edge tension. When the cloth edge tension control device is first installed, it is generally fixed at a specified position by bolts. When the cloth edge tension control device needs to be disassembled and maintained later, tools are required to loosen the bolts for fixing the cloth edge tension control device one by one, which is time-consuming and laborious. Therefore, a weft-jet loom cloth edge tension control device is proposed to facilitate disassembly. Content of the Utility Model

[0003] Aiming at the problems in the prior art, the utility model provides a weft-jet loom cloth edge tension control device.

[0004] The technical solution adopted by the utility model to solve its technical problems is a weft-jet loom cloth edge tension control device, which includes a support. A groove is provided at the top of the support, and a base is arranged in the groove. A hydraulic cylinder and two side plates are fixed at the top of the base. The top of the piston rod of the hydraulic cylinder is fixed with a support plate. A bracket is arranged above the support plate. A roller is rotatably connected inside the bracket. A plurality of vertical rods are fixed at the top of the support plate. A plurality of through holes adapted to the vertical rods are provided at the bottom of the bracket. Two first springs are sleeved on each of the plurality of vertical rods. Blocks are fixed at the tops of the plurality of vertical rods. Two guide rollers are rotatably connected between the two side plates. Two convex blocks are integrally formed at the bottom of the base. A connecting plate is arranged inside the support. Two clamping blocks are fixed at the top of the connecting plate. Slots adapted to the clamping blocks are provided on the side walls of the two convex blocks. One end of the connecting plate extends outside the support and is connected with a baffle. A plurality of insertion rods are fixed on the side of the baffle close to the support. Second springs are sleeved on each of the plurality of insertion rods. A plurality of slots for the insertion rods to be inserted are provided on the side of the support close to the baffle. Connecting blocks are fixed on both sides of the support.

[0005] By adopting the above technical solution, during the first installation, the two connecting blocks are fixed on the air-jet loom by bolts. The fabric is wound around from above one of the guide rollers, then wound around from below the rotating roller, and then wound around from above the other guide roller. During the process of the winding device winding the fabric, the piston rod of the hydraulic cylinder drives the support plate to move downward. With the cooperation of the first spring, the vertical rod, the bracket and the stop block, the fabric is in a straightened state, realizing the control of the edge tension of the fabric. If it is necessary to remove the base together with the side plates, just push the baffle plate towards the support. The connecting plate and the clamping blocks move accordingly, and the two clamping blocks are disengaged from the slots on the side walls of the two convex blocks. The base can be removed by lifting it upward. When installing the base, push the baffle plate, place the base in the groove at the top of the support and then release the baffle plate. The second spring pushes the baffle plate to reset, and the two clamping blocks are inserted into the slots on the side walls of the two convex blocks, facilitating the installation of the base. Only tools are needed during the first installation, and subsequent disassembly and installation do not require tools, saving time and effort.

[0006] Specifically, a handle is fixed on the side of the baffle plate away from the connecting plate, and a first anti-slip sleeve is fixed on the handle.

[0007] By adopting the above technical solution, the setting of the handle and the first anti-slip sleeve is beneficial for gripping and convenient for pushing the baffle plate.

[0008] Specifically, lifting handles are fixed on the opposite side walls of the two side plates, and second anti-slip sleeves are fixed on the two lifting handles.

[0009] By adopting the above technical solution, the setting of the lifting handles and the second anti-slip sleeves is beneficial for gripping and convenient for taking and placing the base and the side plates.

[0010] Specifically, guide blocks are fixed on the opposite side walls of the two side plates, and vertical sliding grooves adapted to the guide blocks are formed on both sides of the bracket.

[0011] By adopting the above technical solution, the cooperation of the guide blocks and the vertical sliding grooves on both sides of the bracket can improve the stability of the bracket.

[0012] Specifically, a bottom plate is fixed at the bottom end of the support.
