Description

Technical Field

[0001] The utility model relates to the technical field of loom equipment, and particularly relates to a yarn tension adjusting device for a loom. Background Technique

[0002] In the process of industrial production, the production of silk thread first requires the use of a spinning machine to produce filaments, and then the silk thread is wound by a winding machine. However, in the process of use, there are situations where the tension is different. According to requirements, the requirements for the size of the silk thread tension are different. When winding, it is very difficult to control the tension of the yarn, which causes trouble to the operators and becomes a problem to be solved in chemical fiber enterprises. In the process of weaving in the textile industry, it is crucial to achieve good control of the yarn tension, which is also the most easily overlooked factor in the spinning process. Without proper tension control, many problems will occur in the normal production process, such as frequent filament breakage and low production efficiency. The document with the patent number "CN217350220U" discloses a loom tension adjusting mechanism, including a support frame and a tension roller, and also includes a second slider, a first slider and multiple hinge groups arranged on the support frame. The multiple hinge groups are arranged in sequence in the vertical direction. The hinge group includes two linkage rods located on the same horizontal plane and intersecting in the middle and hinged to a hinge rod. The ends of the linkage rods in adjacent two hinge groups are hinged to each other. Most of the existing looms generally adjust the spinning tension by adjusting the height of a roller shaft. However, this way of adjusting the tension has limited tension adjustment degree, is more cumbersome in operation, and is not convenient for disassembly and maintenance, thus being not conducive to the normal operation of the loom. For this reason, we propose a yarn tension adjusting device for a loom. Content of the Utility Model

[0003] The purpose of the utility model is to provide a yarn tension adjusting device for a loom to solve the problems raised in the above background technique.

The end of the winding shaft is in transmission connection with a motor through a connecting shaft. Two adjusting shafts are arranged in parallel on both sides of the winding shaft. The ends of the adjusting shafts are connected with a clamping block and a limiting block through screws. The clamping block is clamped in the movable groove on the limit disc, and the side of the clamping block is movably connected with an adjusting screw, and the adjusting screw is in screw connection with the limit disc.

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] Please refer to Figures 1 - 3, the present utility model provides a technical solution: a yarn tension adjusting device for a loom, including a winding shaft 1, the end of the winding shaft 1 is rotatably installed in the mounting hole 22 in the middle of the limit disc 11, a bearing seat 12 is arranged outside the limit disc 11, the end of the winding shaft 1 is in transmission connection with a motor 16 through a connecting shaft 14, two adjusting shafts 17 are arranged in parallel on both sides of the winding shaft 1, the ends of the adjusting shafts 17 are connected with a clamping block 19 and a limit block 2 through screws 18, the clamping block 19 is clamped in the movable groove 21 on the limit disc 11, and the side of the clamping block 19 is movably connected with an adjusting screw 23, and the adjusting screw 23 is in screw connection with the limit disc 11.

[0018] In the above solution, a support column 13 is arranged at the bottom of the bearing seat 12. The bearing seat 12 is supported by the support column 13.

[0019] In the above solution, the motor 16 is installed in a motor seat 15. By arranging structures such as the winding shaft 1, the connecting shaft 14, the motor seat 15 and the motor 16 to cooperate with each other, the motor 16 drives the winding shaft 1 to rotate to wind the yarn, which is simple and convenient to operate, improves the winding and unwinding efficiency of the yarn, and brings convenience to the winding operation of the yarn. Specifically, the motor 16 is a forward and reverse motor, and it is connected to a power supply and a switch through a wire.

[0020] In the above solution, a knob is arranged at the bottom of the adjusting screw 23. By manually rotating the knob to drive the adjusting screw 23 to rotate, the relative distance between the adjusting screw 23 and the limit disc 1 changes, and the adjusting screw 23 drives the clamping block 19 to move up and down, so as to adjust the position of the adjusting shaft 17, achieving the purpose of adjusting the distance between the adjusting shaft 17 and the winding shaft 1.

[0021] In the above solution, the clamping block 19 is fixedly connected to the limit block 2. By arranging the limit block 2 outside the clamping block 19, the adjusting shaft 17 can be prevented from shaking, thereby improving the stability of the device.

[0022] In the above solution, two groups of adjusting shafts 17 are arranged. The adjusting shaft 17 and the winding shaft 1 cooperate to form a winding mechanism, and the adjusting shaft 17 is used as a tension adjusting mechanism to adjust the tension of the yarn.

[0023] In the above solution, the bearing seat 12 and the limit disc 11 are in plug-in fit. It is convenient to disassemble and maintain the device.

[0024] By arranging adjusting shafts 17 on both sides of the winding shaft 1 and through the cooperation of structures such as clamping blocks 19, movable slots 21, adjusting screws 23, etc., the position of the adjusting shaft 17 can be adjusted. When the adjusting shaft 17 is far from the winding shaft 1, the tension of the yarn becomes larger. When the adjusting shaft 17 is close to the winding shaft 1, the tension of the yarn becomes smaller. Moreover, the end of the adjusting shaft 17 is detachable, and the yarn can be unloaded from the adjusting shaft 17. The operation is simple, and the tension of the yarn can be changed as needed, so as to meet different usage requirements.

[0025] Working principle:

[0026] When the yarn tension adjusting device for this loom is specifically used, the yarn is wound around the winding shaft 1. The motor 16 drives the winding shaft 1 to rotate through the connecting shaft 14, so that the yarn is in a winding state on the winding shaft 1, and the yarn is bypassed around the adjusting shaft 17, and the yarn is tensioned by the adjusting shaft 17. During this process, the position of the adjusting shaft 17 is adjusted by manually rotating the adjusting screw 23. When the adjusting shaft 17 is far from the winding shaft 1, the tension of the yarn becomes larger. When the adjusting shaft 17 is close to the winding shaft 1, the tension of the yarn becomes smaller. The operation is simple, and the tension of the yarn can be changed as needed, so as to meet different usage requirements.

[0027] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
