A buffer of a let-off mechanism with adjustable reaction speed and an application method thereof

Abstract

The invention discloses a let-off mechanism buffer with adjustable response speed, which comprises a buffer cylinder body, a piston, an adjusting bolt, an air intake pipe and a high-pressure air pump. The piston is arranged in the buffer cylinder body, and the buffer cylinder body is hollow. It is cylindrical and one end is sealed and the other end is open. The sealing end of the buffer cylinder is provided with a first through hole. The adjustment bolt passes through the first through hole. The adjustment bolt is located inside the buffer cylinder and one end is fixed with a compression spring. The other end is fixed with a bottom plate; four circular through holes are evenly spaced on the lower gasket in the piston body; in actual operation, the four circular through holes on the upper gasket and the lower gasket can be aligned according to the requirements of different products. The staggered positions of the through holes, the length of the adjusting bolts extending into the buffer cylinder and the air pressure in the buffer cylinder are adjusted comprehensively to achieve the purpose of accurately adjusting the response speed of the buffer and ensure the timely warp let-off of the weaving beam and the weaving quality and efficiency.

Description

technical field [0001] The invention relates to a let-off mechanism buffer with adjustable response speed and an application method thereof, belonging to the technical field of textile equipment. Background technique [0002] At present, the working principle of the adjustable let-off mechanism of the loom is that the weaving shaft overcomes the braking torque and rotates under the action of the warp tension, so that the warp yarn is released from the weaving shaft to complete the let-off action. During the let-off process, the let-off amount is determined by A special adjustable let-off mechanism is used for adjustment; the let-off amount of the adjustable let-off is determined by the warp tension state at that time, so the adjustable let-off mechanism generally uses the rear beam as a tension sensor, and adjusts the rotation of the weaving shaft through a buffer The amount of warp yarns can be changed accordingly, the response speed of the buffer, the controllability of th...

Problems solved by technology

[0003] At present, the existing buffer used in the textile industry adopts the piston structure of the oil system. In order to achieve the effect of timely warp let-off of the weaving beam, the piston is drilled with an oil guide hole to connect the upper and lower oil chambers to speed up the reaction of the buffer; The buffer lacks adjustability and cannot adapt to the response speed requirements of the let-off mechanism for different cloth products; at the same time, due to the faster response speed of the buffer, it is easy to cause obvious gaps on the cloth during the weaving process, which greatly affects the cloth. poor textile quality, resulting in a waste of raw materials and an increase in cost

[0004] The response of the buffer directly affects the amount of warp let-off, and thus the uneven tension affects the quality and efficiency of weaving. It is urgent for those skilled in the art to develop a buffer for the let-off mechanism of textile machines that can overcome the above-mentioned defects. technical problem
