Description

Technical Field

[0001] This utility model relates to the field of jacquard machine technology, specifically to an opening device for a jacquard machine. Background Technology

[0002] In the textile industry, jacquard machines are key equipment for weaving complex patterns. The performance of their shedding devices directly affects weaving efficiency and fabric quality. Traditional shedding devices suffer from problems such as low transmission accuracy, slow response speed, high energy consumption, and high maintenance costs, making it difficult to meet the demands of modern high-value-added fabrics for fine and high-speed weaving. Therefore, the development of new shedding devices that are high-precision, low-energy, and adaptable to diverse patterns is of great practical significance.

[0003] Existing jacquard machine shedding devices directly guide the warp yarns into the device for processing. The warp yarns will have surface wrinkles and bends, which can lead to warp yarn breakage and fabric defects, thus affecting the production efficiency of the jacquard machine. Utility Model Content

[0004] The purpose of this invention is to provide an opening device for a jacquard machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an opening device for a jacquard machine, comprising a main frame, side plates fixedly connected to the top left and right ends of the main frame, a warp tension control mechanism provided on the surface of the side plates, an opening mechanism provided on the surface of the side plates, a base fixedly connected to the bottom end of the main frame, an assembly top plate fixedly connected to the top of the inner end of the side plates, and a control console installed on the top right front end of the base.

[0006] The warp tension control mechanism includes a first mounting frame, which is fixedly connected to the front of a side plate. A second mounting frame is fixedly connected to the front of the side plate. A screw is rotatably connected to the inner end of the first mounting frame, and a servo motor is mounted on the top of the first mounting frame.

A tension adjusting roller is installed inside the sliding seat. When the jacquard machine is in use, the yarn will be adjusted by the warp tension control mechanism before entering the sheathing mechanism. According to the requirements, the servo motor is controlled to drive the screw to rotate, which drives the sliding seat to move, thereby changing the height of the tension adjusting roller. Multiple sets of tension adjusting rollers form different height differences to adjust the warp tension and maintain its stability. Stable warp tension helps to improve the clarity and stability of the shed and reduce the occurrence of warp breaks and fabric defects.

The adjusted yarn enters the shedding mechanism for further processing. The shedding mechanism can control the adjusting screw to drive the slide to move up and down through a servo-controlled motor, thereby changing the distance between the first shed support plate and the second shed support plate. The height of the first shuttle plate and the second shed plate can be adjusted through the electrically controlled telescopic column, thereby achieving fine-tuning between the first shed plate and the second shed plate, making the work smoother. The height adjustment range should meet the weaving needs of fabrics with different thicknesses and structures, ensuring that the weft yarn can be smoothly introduced into the shed, ensuring that the shedding device maintains stable and precise movement during high-speed operation, and improving the overall weaving performance of the jacquard machine.

According to the needs, the servo motor drives the screw to rotate, which drives the sliding seat to move, thereby changing the height of the tension adjusting roller. Multiple sets of tension adjusting rollers form different height differences to adjust the warp tension and maintain its stability. Stable warp tension helps to improve the clarity and stability of the shed and reduce the occurrence of warp yarn breaks and fabric defects.

[0014] The shedding device of this jacquard machine is equipped with a shedding mechanism. The adjusted yarn enters the shedding mechanism for further processing. The shedding mechanism can be controlled by a servo-controlled motor to move the adjusting screw up and down, thereby changing the distance between the first and second shedding support plates.
