Description

Compression roller pressurizing damping mechanism of warp beam

Technical Field

The invention relates to a compression roller pressurizing damping mechanism of a warp beam.

Background

The warping machine needs a compression roller to pressurize a warp beam, and a compression roller to warp beam pressurizing mechanism is arranged on a track. During pressurization, the track needs enough damping force to ensure that the compression roller is kept stable in the pressurization process and cannot move back and forth. If there is a cross-talk, the wound beam yarn can become out of round and an unacceptable product can result. But when the yarn is broken, the press roller is required to be quickly separated from the warp beam, so that the abrasion of the yarn is reduced.

Disclosure of Invention

The invention aims to overcome the defects in the prior art and provide a compression roller pressurizing damping mechanism of a warp beam, which ensures the stability of the compression roller in the pressurizing process when the compression roller pressurizes the warp beam, and the warp beam does not move back and forth, and the wound warp beam yarn does not become out of round, thereby not forming unqualified products. When the yarn is broken, the press roller can be quickly separated from the warp beam, and the abrasion of the yarn is reduced.

In order to achieve the purpose, the technical scheme of the invention is to design a compression roller pressurizing damping mechanism of a warp beam, which comprises a sliding block arranged on a track in a sliding manner, wherein the sliding block is connected with a compression roller through a connecting piece, a damping pressurizing cylinder is fixedly arranged above the sliding block, a through hole for accommodating a cylinder piston of the damping pressurizing cylinder is arranged in the middle of the sliding block, and a pressurizing piston and a damping sheet are sequentially arranged in the through hole and positioned below the cylinder piston. The slide block is driven by a driving mechanism to realize the forward and backward translation on the track so as to realize the pressurization of the warp beam by the compression roller; and the damping pressurization cylinder moves after the compression roller presses the warp beam, so that the damping sheet tightly abuts against the sliding rail, and the sliding block cannot move back and forth.

The further technical scheme is that the lower surface of the damping sheet is flush with the lower surface of the sliding block. Thus, the damping sheet does not interfere with the sliding of the slider when the slider slides, and is pressed on the track through the action of the damping pressurizing cylinder when the slider is required to be kept and not to move.

The further technical proposal is that two tracks are arranged and are respectively positioned at two sides of a roller shaft of the compression roller; the track is I-shaped steel.

The further technical scheme is that a through hole in the middle of the track is a stepped hole with a small upper part and a large lower part, the damping sheet is matched with the large-size hole of the stepped hole, and the cylinder piston and the pressing piston are arranged in the small-size hole of the stepped hole in a sliding mode. The damping fin sets up a little as far as possible, covers more track surfaces, guarantees the effect of steady slider.

The further technical scheme is that an elastic piece is arranged between the cylinder piston and the pressing piston, and the elastic piece is vertically abutted against the cylinder piston and the pressing piston respectively.

The further technical scheme is that the elastic piece is a steel type spring and/or a belleville spring. After the arrangement, the direct contact between the cylinder piston and the pressure applying piston is reduced, the service lives of the cylinder piston and the pressure applying piston are prolonged, and the abrasion between the cylinder piston and the pressure applying piston is reduced.

The further technical proposal is that the compression roller is rotationally arranged on the connecting piece.

The further technical scheme is that the connecting piece is an L-shaped folded plate arranged on two sides of the pressing roller shaft, the pressing roller shaft penetrates through the L-shaped folded plate, and the pressing roller is arranged in a rotating mode relative to the L-shaped folded plate.

The invention has the advantages and beneficial effects that: the corrugated rubber elastic piece is arranged between the cylinder piston and the pressure applying piston, so that the direct contact between the cylinder piston and the pressure applying piston can be reduced, the service lives of the cylinder piston and the pressure applying piston are prolonged, and the abrasion between the cylinder piston and the pressure applying piston is reduced. The damping pressurization cylinder presses the back action to the warp beam at the compression roller for the damping fin tightly supports and leans on the slide rail, makes the slider can not cluster from beginning to end. The damping fin sets up a little as far as possible, covers more track surfaces, guarantees the effect of steady slider. When the compression roller pressurizes the warp beam, the stability of the compression roller in the pressurizing process is ensured, the compression roller does not move back and forth, the wound warp beam yarn is not out of round, and unqualified products cannot be formed. When the yarn is broken, the press roller can be quickly separated from the warp beam, and the abrasion of the yarn is reduced.
