Description

Technical Field

[0001] The utility model belongs to the field of fabric processing, and particularly relates to an auxiliary tensioning device for processing sling canvas sleeves. Background Technique

[0002] In China's textile industry, automated textile machinery has now been widely adopted. After the fabric is tensioned by a tensioning mechanism, it is cut. The cut fabric needs to ensure that the cut is smooth and continuous to guarantee the quality of the product after the remaining processes.

[0003] Some auxiliary tensioning devices for processing canvas sleeves have been specifically developed in the prior art. For example, the Chinese patent with the publication number "CN209567630U" discloses "a fabric stretching and tensioning device". When in use, first loosen the setscrew, then clamp one end of the fabric into the round rod U-shaped clamping rod, tighten the corresponding setscrew, clamp the other end of the fabric into another U-shaped clamping rod, and then rotate the knob to drive the screw to rotate. The screw drives the vertical slider threadedly connected thereto to slide downward in the vertical slide rail. The connecting rod drives the two collar rings to move downward along the straight groove rod. While the collar rings move downward, they drive the two straight groove rods to swing to both sides. The two straight groove rods drive the round shafts in the one-end chute to move away from each other. The two round shafts respectively drive the vertical rods, the cross rods and the sliders to move away from each other along the slide rail. The two U-shaped clamping rods move away from each other to stretch the fabric until the fabric is tensioned. The U-shaped clamping rod drives the T-shaped rod to move along the round hole passing through the cross rod, and the spring is compressed. Stop rotating the knob, and the screw and the vertical slider are threadedly self-locked, and then subsequent operations are performed on the fabric. This device can stretch and tension fabrics of different lengths and protect the fabric from being damaged.

[0004] Although the fabric can be effectively tensioned by moving the two U-shaped clamping rods away from each other to stretch the fabric, when in use, the cut fabric needs to be placed inside the clamping rod, and the shearing integration cannot be effectively realized, which increases the workload of the staff. Moreover, the staff needs to place both ends of the cut fabric inside the clamping frame, which will increase the cumbersome degree of the staff. The two sides of the screw need to be turned to fix both ends of the fabric, and the portability cannot be effectively improved. Content of the Utility Model

[0015] To sum up, the main beneficial effects of the present utility model are as follows:

[0016] First, when in use, one end of the cloth roller rotatably installed at the upper end of the bottom plate is pulled into the first clamping plate. When pulling the cloth to the first clamping plate, it needs to pass through the second clamping plate. Then, by manually rotating the second screw rod, the first clamping plate will clamp the head end of the cloth under the rotation of the second screw rod, which can effectively fix the cloth. When a certain length needs to be cut, by rotating the turntable, the first sliding column and the second sliding column are driven to move, which can effectively realize the length of the cloth to be processed. Finally, when the driving motor is started to rotate, the second clamping plate is pushed, and then the second clamping plate can effectively clamp the cloth. When the air cylinder is started, the air cylinder pushes the cutter to cut the cloth, which can effectively cut the cloth, facilitate cutting the cloth and can effectively realize the length of the cloth to be cut. When the cloth needs to be tensioned, the first sliding column and the second sliding column can also be driven by rotating the turntable to effectively tension the cloth, improving the portable effect;

[0017] Second, when tensioning the cloth, since the connecting column is slidably installed inside the first fixed plate, and a spring is fixedly installed on the outer ring of the connecting column, it can play a buffering role and can also prevent the cloth from being pulled off due to excessive force, improving the quality of the cloth. A roller is rotatably installed at one end of the second fixed plate, and the roller can effectively prevent the cloth from being broken due to friction with the second fixed plate when being pulled, improving the integrity of the cloth. Anti-slip pads are fixedly installed at the bottoms of the first clamping plate and the second clamping plate, which can effectively improve the effect of fixing the cloth when pressing the cloth.
