Description

An automatic doffing roving frame that can reduce noise

technical field

The utility model relates to a textile machine, in particular to an automatic doffing roving machine which can reduce noise.

Background technique

The automatic doffing roving machine is the machine used by most textile mills when spinning and doffing.

The Chinese patent with the existing authorization announcement number CN202202057U provides an automatic doffing roving frame, which includes a roving frame body, a lower rib removal mechanism, a lower rib lifting mechanism, and a doffing and doffer circulation mechanism; When moving out, the lift reducer drives the lifting wheel of the lift drive shaft to rotate, and drives the doffer cover plate (doffer) to lift and lower through the sling; when the doffer descends to a certain position, the full yarn can be filled by the hanging spindle fixed on the rotating steel belt. The bobbin is hoisted, and then the doffer rises to a certain position. Through the steel belt rotating device, the rotating steel belt is rotated at a fixed distance, the doffer descends, and the empty bobbin is released on the wood tube wheel. Return to the spinning position for the next round of spinning.

However, during the spinning process, the bobbin and the bottom of the bobbin gear rotate and rub, and when a large number of bobbins rotate at the same time, the sound is too loud, resulting in noise, so it needs to be improved.

Utility model content

In view of the deficiencies in the prior art, the purpose of the present invention is to provide an automatic doffing roving frame capable of reducing noise, which has the advantage of reducing noise.

At the same time, the inner tube can penetrate the outer tube, and the position of the inner tube is limited by the elastic pressing block to prevent the inner tube from falling and hitting staff member.

Further, a limiting block is provided at one end of the elastic pressing block where the inner tube is inserted.

By adopting the above technical solution, when the elastic pressing block defines the position of the inner tube, the elastic pressing block is prevented from slipping off.

Further, both ends of the spring are fixedly provided with a spring fixing seat, and the spring fixing seat is detachably connected with the elastic pressing block.

By adopting the above technical solution, when the elasticity of the spring in the elastic pressing block is insufficient, the detachable connection between the spring fixing seat and the elastic pressing block facilitates the replacement of the spring.

Further, the center of the spring fixing seat is fixedly provided with a magnetic member.

By adopting the above technical solution, when the inner tube needs to penetrate the outer tube, the elastic pressing block is pressed, and the magnetic parts on the spring fixing seat are attracted to each other, thereby preventing the elastic pressing block from popping out. When the inner tube moves, the elastic pressing block is sent to the outer tube friction.

Further, the end wall of the elastic pressing block located outside the inner tube is fixedly provided with a pressing cushion.

By adopting the above technical solution, when the elastic pressing block is pressed, the elastic soft pad prevents the operator from being scratched.

Further, the end wall of the inner tube facing away from the outer tube is provided with a rubber pad.

By adopting the above technical solution, when the support tube supports the support plate, the rubber pad prevents the inner tube from rubbing against the ground and causing wear.

Further, the rubber pad is provided with a circular groove for inserting the inner tube.

By adopting the above technical solution, when the rubber pad is worn too seriously, the detachable rubber pad can be easily replaced.

Further, the end wall of the inner tube into which the circular groove is inserted is provided with a guide surface.

By adopting the above technical solution, it is convenient to insert the inner tube into the circular groove of the rubber pad.

To sum up, the utility model has the following beneficial effects:

1. The sound-absorbing material on the support plate effectively reduces the noise during the operation of the automatic doffing roving frame;

2. The elastic pressing block limits the relative position of the inner tube and the outer tube;

3. The rubber pad avoids the friction between the lower end of the inner tube and the ground, which leads to the wear of the inner tube.
