Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to a tentering component of a jacquard fabric. Background Art

[0002] The jacquard fabric can effectively improve its physical properties after the tentering treatment, making it have sufficient strength and toughness.

[0003] The existing tentering assembly usually uses two clamping plates to clamp the edge of the fabric. After the fabric is clamped, the fabric is tensioned when an external force is applied, thereby ensuring that the warp or weft yarn is stably tensioned.

[0004] It can be seen that since the two clamps cannot fit completely together, part of the fabric cannot be stably clamped and positioned when the fabric is clamped, resulting in wrinkles in the fabric during the stretching operation, affecting the stability of the finished fabric. Summary of the invention

[0005] The utility model aims to provide a tentering assembly for jacquard fabrics with high stability and compact structure in view of the above problems existing in the prior art.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A tentering assembly for jacquard fabrics, the tentering device for jacquard fabrics comprises a frame, the frame is provided with a workbench for placing the jacquard fabrics, and is characterized in that the tentering assembly comprises a guide rail, a cross bar, a connecting seat and a chuck, the guide rail is fixedly connected to the frame and is located on the side of the workbench, the cross bar is connected to the guide rail and can translate along the guide rail under the action of external force, the connecting seat is in the shape of an elongated strip, the connecting seat is fixedly connected to the upper edge of the cross bar and the two are arranged in parallel, the number of the chucks is several, the several chucks are evenly distributed along the length direction of the connecting seat, and the several chucks are adjacent to the edge of the workbench.

[0008] The stentering assembly of the jacquard fabric creatively sets a plurality of clamps on the cross bar. Since the clamps are evenly distributed along the length direction of the cross bar, each clamp is clamped at the corresponding position of the edge of the fabric, which can ensure that the fabric is evenly clamped, and no local position looseness will occur during the stentering operation, thereby effectively improving the fabric stentering effect.

[0009] Since there are not too many connection positions between the clamp and the cross bar, the clamp and the cross bar can be stably connected together under the action of the connecting seat.

[0010] At the same time, since the cross bar is connected to the guide rail, when the clamps are clamped and connected with the fabric, the cross bar can drive all the clamps to move synchronously, thereby stably completing the stretching operation.

[0011] In the above-mentioned jacquard fabric stretching assembly, the number of the guide rails is two, the two guide rails are arranged in parallel and are respectively located on both sides of the workbench, and the two ends of the above-mentioned cross bar are respectively connected to the corresponding guide rails.

[0012] The arrangement of the two guide rails can improve the movement stability of the crossbar.

[0013] In the above-mentioned jacquard fabric stretching assembly, the edge of the workbench is provided with a concave avoidance notch, and the above-mentioned avoidance notch is arranged in a one-to-one correspondence with the clamping head.

[0014] The avoidance recess is used to avoid the corresponding chuck to prevent the chuck from contacting the workbench.

[0015] At the same time, since the fabric is located at the avoidance recess, the clamping head can stably clamp the fabric after extending into the avoidance recess.

[0016] In the above-mentioned jacquard fabric stretching assembly, the chuck is a pneumatic chuck.

[0017] Several chucks all use the same air circuit system, and all chucks are centrally controlled by changing the air circuit system.

[0018] In the above-mentioned jacquard fabric stretching assembly, the connecting seat includes a plate body 1 and a plate body 2 in the shape of a plate, the plate body 2 is vertically fixed to one edge of the plate body, the inner ends of the above-mentioned clamps are respectively fixed to the body 1 and the body 2, the plate body 1 is in contact with the cross bar surface and the two are fixedly connected by fasteners.

[0019] After the plate body 2 contacts the crossbar surface, it can ensure that the connecting seat is stably fixed on the crossbar.

[0020] In the above-mentioned jacquard fabric stretching assembly, sliders are respectively fixedly connected to both ends of the crossbar, and the sliders are connected to corresponding guide rails.

[0021] Under the action of the slider, the end of the crossbar can be stably connected to the guide rail. Since the contact area between the slider and the guide rail is relatively large, the crossbar can eventually translate stably along the guide rail.

[0022] In the above-mentioned tentering assembly of the jacquard fabric, the bottom of the avoidance notch is arc-shaped.

[0023] The arc-shaped structure at the bottom of the avoidance notch can avoid the fabric from getting stuck, and effectively improve the clamping stability of the fabric by the clamp.

[0024] In the above-mentioned jacquard fabric stretching assembly, the height position of the working table is the same as the height position of the clamping head.

[0025] When the chuck moves horizontally along the guide rail along with the cross bar, the chuck can stably enter the edge of the fabric.

[0026] Compared with the prior art, the jacquard fabric stretching assembly adopts multiple evenly distributed clamps to clamp the fabric on the workbench. Therefore, the fabric will not become loose at any position during the stretching process, which will affect the quality of the finished product. Therefore, the stretching stability of the stretching assembly is relatively high.

[0027] At the same time, a plurality of clamps are evenly arranged on the connecting seat, and the connecting seat is connected to the cross bar, so the overall structure is compact and has high practical value. BRIEF DESCRIPTION OF THE DRAWINGS
