Description

Technical Field

[0001] This utility model belongs to the technical field of spinning equipment and relates to an air duct with an automatically adjustable position. Background Technology

[0002] A side-blowing air duct is a side-blowing device used at the spinning position. Its function is to simulate the effect of ring-blowing cooling without changing the equipment, thereby improving the uniformity of filament cooling during spinning.

[0003] The side slide plates on both sides of the side-blowing air frame are devices for fixing the air frame and providing lifting and lowering of the air frame. Traditional air duct side slide plates are like... Figure 1 As shown, it is mainly fixed to the side plate of the side blowing device by four screws tightened from top to bottom through four screw holes.

[0004] Because the fan frame is heavy and needs to be raised and lowered every day during the cleaning process, long-term impacts can cause the screws and screw holes to loosen. The screws may shift in position within the screw holes, causing the side slide plates to frequently become misaligned, affecting the cooling effect and production stability.

[0005] The current solution is to manually tighten the screws periodically, but after multiple repairs, the screw holes are prone to stripping and becoming unusable, requiring re-drilling and repositioning, which is cumbersome and affects production efficiency. At the same time, changing batches requires replacing the air duct with different specifications and adjusting the air duct position. Due to the small width of the screw holes, adjustment is inconvenient, and when the adjustment range is large, it cannot meet the position adjustment requirements well, and cannot achieve flexible adjustment.

[0006] Furthermore, traditional ventilation duct equipment cannot respond promptly to production anomalies, such as inconsistent heights between spinning positions, uneven heights within the same spinning position, misaligned ventilation frames, or ventilation frames falling during production. These issues rely solely on repeated manual inspections, failing to detect problems in a timely manner. By the time problems are discovered, a significant amount of time has passed, resulting in defective products and severely impacting product quality.

[0007] Therefore, given that traditional ventilation ducts cannot detect deviations and misalignments of the ventilation frame in a timely manner, and that adjusting the position of the ventilation frame is inconvenient, it is necessary to develop a new type of ventilation duct that can automatically adjust its position. Utility Model Content

[0008] The purpose of this invention is to solve the above-mentioned problems existing in the prior art and to provide a wind duct with an automatically adjustable position.

[0009] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0010] An automatically adjustable air duct includes an upper guide rail, a lower guide rail, a third guide rail, a first gear, a second gear, a third gear, a fourth gear, a fifth gear, a sixth gear, a first chain, a second chain, a third chain, a first motor, a second motor, a first control switch, a second control switch, a side slide plate, a slide rail, an air frame, a slider, a laser positioning transmitter, and a laser positioning receiver alarm.

[0011] The fixed shaft of the first gear is fixed at one end of the lower surface of the upper guide rail, and the fixed shaft of the second gear is fixed at the other end of the lower surface of the upper guide rail. The first chain is ring-shaped and is fitted on the first and second gears. The rotating shaft of the first motor is fixedly connected to the rotating shaft of the second gear. The upper end of the side slide is fixed to one side of the first chain.

[0012] The fixed shaft of the third gear is fixed at one end of the upper surface of the lower guide rail, and the fixed shaft of the fourth gear is fixed at the other end of the upper surface of the lower guide rail. The second chain is a ring and is fitted onto the third and fourth gears. The lower end of the side slide is fixed to one side of the second chain. The side slide is located on the same side of the first and second chains.

[0013] The first control switch is connected to the first motor to control the forward or reverse rotation of the first motor, which drives the first chain to rotate forward or reverse, so that the side slide moves back and forth along the upper and lower guide rails.

[0014] The slide rail and the third guide rail are set on the same side of the side slide plate. The laser positioning transmitter is movably fixed to the slide rail by a buckle. The fixed shaft of the fifth gear is fixed to one end of the third guide rail, and the fixed shaft of the sixth gear is fixed to the other end of the third guide rail. The fifth gear and the sixth gear are located on the same side of the third guide rail. The rotating shaft of the fifth gear is fixed together with the rotating shaft of the second motor. The second motor is connected to the second control switch by a wire. The third chain is ring-shaped and fits on the fifth gear and the sixth gear. The inner chain of the third chain is close to the side slide plate, and the outer chain of the third chain is away from the side slide plate. The outer chain of the third chain is provided with a slot with an outward opening. The slider and the laser positioning receiver alarm are fixed to the wind frame. The laser positioning receiver alarm is connected to the second control switch by a wire. The wind frame is detachably fixed to the third chain by buckling the slider and the slot.

[0015] When the laser positioning receiver alarm does not correspond to the position of the laser positioning transmitter, the laser positioning receiver alarm will not receive the beam emitted by the laser positioning transmitter. The laser positioning receiver alarm will sound an alarm and close the second control switch, start the second motor, and drive the third chain to rotate, so that the wind frame and the laser positioning receiver alarm move up and down.

[0016] When the laser positioning receiver alarm moves to a position corresponding to the laser positioning transmitter, the laser positioning receiver alarm receives the beam emitted by the laser positioning transmitter, and the second control switch is turned off, the second motor stops working, and the wind frame is fixed on the side plate.

[0017] As a preferred technical solution:

[0018] As described above, the automatically adjustable air duct has two slots and two sliders. The slots are evenly distributed on the outer chain of the third chain, and the sliders are evenly distributed on the air frame, which helps to stably fix the air frame on the side slide plate.

[0019] As described above, the automatically adjustable air duct has a guide groove on the side slide plate. The guide groove and the laser positioning transmitter are located on the same side of the third guide rail. The number of guide grooves is the same as the number of slots. The function of the guide groove is to guide the installation of the air frame. First, align the slots of the side slide plate with the guide grooves, then insert the slider of the air frame into the guide groove, then push the air frame along the guide groove, and finally the slider of the air frame is locked into the slot.

[0020] As described above, the automatically adjustable air duct also has a handrail on the air frame. The handrail is designed to make it easy to grip and allow the slider on the air frame to smoothly enter or exit the slot, facilitating the installation of the air frame and making it easy to disassemble the air frame for cleaning or batch changes.

[0021] Beneficial effects:

[0022] (1) This utility model uses laser beam positioning, which can detect the deviation and misalignment of the wind frame in a timely manner.

[0023] (2) This utility model uses a motor drive to make the wind frame move in the up and down direction and the front and back direction. In particular, the wind frame can move automatically in the up and down direction according to the positioning result of the laser beam, making the position adjustment of the wind frame simple and convenient.

[0024] (3) The present invention has a simple structure, low cost, high efficiency, and is suitable for side-blown spinning position cooling in the spinning process, which is beneficial to improving the uniformity of fiber bundle cooling. Attached Figure Description
