Description

A kind of draw-off mechanism of tricot machine

Technical field

The utility model relates to textile technology field, and more particularly, it relates to a kind of tricot machine.

Background technology

Tricot machine is mainly made up of knitting mechanism, guide bar shogging mechanism, let-off mechanism, tractive spooler, spooler and transmission mechanism. Wherein, be parallel to each other, spaced the first pulling roll, the second pulling roll and the 3rd pulling roll successively from inside to outside; Described first, second, and third pulling roll is all arranged on supporting base rotationally, and first, second, and third pulling roll drives rotation by gear drive. Owing to there is certain gap between the first pulling roll and the second pulling roll, foreign material are just easy to enter in spooler from this gap location, and the quality of cloth is caused to harmful effect. Therefore, adopt arranges a pressure roller more between the first pulling roll and the second pulling roll at present, fills up this gap, thereby makes up above-mentioned defect. But, in the time of operation, this pressure roller can follow the first pulling roll and the second pulling roll is rotated, and because the weight of pressure roller is generally all larger, also higher to the thrust of fabric, if operator is accidentally, hand is placed on to the crevice place of pressure roller and the first or second pulling roll, will be easy to can hand folding. Therefore,, for this problem, new technical scheme need to be proposed.

Utility model content

The deficiency existing for prior art, the purpose of this utility model is to provide a kind of draw-off mechanism of tricot machine, by original pressure roller is replaced with to press strip, and then in ensureing to prevent that foreign material from entering spooler, can also prevent the feature that operator's hand is pressed from both sides.

For achieving the above object, the utility model provides following technical scheme:

A draw-off mechanism for tricot machine, comprise be parallel to each other, spaced the first pulling roll, the second pulling roll and the 3rd pulling roll successively from inside to outside; Described first, second, and third pulling roll is all arranged on supporting base rotationally, and first, second, and third pulling roll drives rotation by gear drive, also comprises that one is arranged on the press strip before the first pulling roll and the second pulling roll; Described press strip entirety is L-shaped, comprises respectively and the first plate body and second plate body of the roll surface laminating of the first pulling roll and the second pulling roll, and the junction of described the first plate body and the second plate body is circular arc setting; Described the first plate body and the second plate body are all inwards bending, and crooked radian is identical with the radian of the first pulling roll and the second pulling roll respectively.

Further, described the second plate body, away from the side direction bending to the inside of the first plate body, forms the flange of circular arc.

Further, described the first plate body and the second plate body are being provided with perforate near on the plate face at its two ends.

Compared with prior art, the utility model has the advantages that: by above scheme, draw-off mechanism is in the time of operation, cloth is wound on first, second, third tractive axle, then just press strip can be placed on the cloth between the first pulling roll and the second pulling roll, now, the cloth pasting in the first plate body and first pulling roll of press strip, fabric laminating in the second plate body and the second pulling roll, thereby by the gap filling between the first pulling roll and the second pulling roll. Because press strip can not followed and rotate, thus the problem that can avoid operator's hand to be pressed from both sides.

Detailed description of the invention

With reference to Fig. 1, a kind of draw-off mechanism of tricot machine, comprise be parallel to each other, spaced the first pulling roll 1, the second pulling roll 2 and the 3rd pulling roll 3 successively from inside to outside; First, second, and third pulling roll 3 is all arranged on supporting base 4 rotationally, and first, second, and third pulling roll 3 drives rotation by gear drive, also comprises that one is arranged on the press strip 5 before the first pulling roll 1 and the second pulling roll 2.

With reference to Fig. 2 A, Fig. 2 B, press strip 5 entirety is L-shaped, comprises respectively with the first plate body 51 of the roll surface laminating of the first pulling roll 1 and the second pulling roll 2 and the junction of the second plate body 52, the first plate bodys 51 and the second plate body 52 and is circular arc setting; The first plate body 51 and the second plate body 52 are all inwards bending, and crooked radian is identical with the radian of the first pulling roll 1 and the second pulling roll 2 respectively.

By above scheme, draw-off mechanism is in the time of operation, cloth is wound on first, second, third tractive axle, then just press strip 5 can be placed on the cloth between the first pulling roll 1 and the second pulling roll 2, now, cloth pasting in the first plate body 51 and first pulling roll 1 of press strip 5, the fabric laminating in the second plate body 52 and the second pulling roll 2, thereby by the gap filling between the first pulling roll 1 and the second pulling roll 2. Because press strip 5 can not followed and rotate, thus the problem that can avoid operator's hand to be pressed from both sides.

In addition, because the width bearing of trend of the second plate body 52 and the direct of travel of cloth are in opposite directions, so cloth in the time transmitting, the decorative pattern part of protruding on cloth, probably can be scraped by the edge of the second plate body 52, cause the quality problems of cloth, therefore, in order to address this problem, side direction bending to the inside by the second plate body 52 away from the first plate body 51, and then form the flange 54 of circular arc, only contacted with cloth by the circular arc portion in the outside of this flange 54, thereby avoid cloth scratch.

In addition, because the laminating degree of press strip 5 and the first pulling roll 1 and the second pulling roll 2 is higher, so in the time that press strip 5 is picked up, operator can only catch flange 54, but simultaneously, press strip 5 is generally all very long, approximately 3-4 rice, so can be heavier, if operator only catches flange 54, in the time picking up pressing plate, can easily skid, therefore, with reference to Fig. 2 A, for handled easily workman picks up press strip 5, be provided with perforate 53 at the first plate body 51 and the second plate body 52 near on the plate face at its two ends. By this perforate 53 is set, operator's finger just can be buckled in this perforate 53, can not skid.

The above is only preferred embodiment of the present utility model, and protection domain of the present utility model is also not only confined to above-described embodiment, and all technical schemes belonging under the utility model thinking all belong to protection domain of the present utility model. It should be pointed out that for those skilled in the art, in the some improvements and modifications that do not depart under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
