Abstract

The utility model discloses a bidirectional winding machine of a coating machine. The winding machine comprises a rack as well as a winding lever, a pre-tightening device and a guide device which are connected onto the rack sequentially from left to right, wherein a piece of cloth to be wound is wound from right to left; a winding device and a back winding device are arranged at left and right ends of the winding lever respectively and perform bidirectional winding on the cloth to be wound; a first-direction winding line comprises the guide device, the pre-tightening device and a front winding device; a second-direction winding line comprises the guide device, the pre-tightening device, the back winding device, the front winding device and the back winding device. According to the winding machine, the structural form that the front winding device and the back winding device are arranged at two ends of the winding lever to wind the cloth simultaneously is adopted, and the front winding device is provided with a buffer period, so that phenomena of folds and inconsistent tightness due to the fact that the front winding device winds the cloth too fast are avoided; in addition, the back winding device is added, so that the winding efficiency is improved.

Description

The two-way winder of a kind of coating machine

Technical field

The utility model relates to coating machine technical field, particularly relates to the two-way winder of a kind of coating machine.

Background technology

Existing coating machine winder, adopt guide piece and pre-tightening apparatus, wrap-up, the cloth that coating is finished carries out rolling, but because the rolling speed of winder is very fast, the cloth after rolling there will be fold phenomenon, if the speed of winder is excessively slow, can cause again the elasticity of the cloth after rolling not too consistent, make fraction defect higher, the yardage roll poor quality who obtains, the later stage that affects yardage roll is used.

Utility model content

In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of coating machine two-way winder, and its object is to avoid the cloth fold of rolling, ensures that the elasticity of the cloth after rolling is consistent, thereby improve the quality of the cloth of rolling, reduce the fraction defect of yardage roll.

The technical scheme that the utility model adopts is: the two-way winder of a kind of coating machine, comprise frame, and be connected to from left to right the rolling lever in frame in turn, pre-tightening apparatus, guide piece, the rolling from right to left of the cloth of required rolling, two ends, rolling lever left and right are provided with respectively wrap-up and rear wrap-up, wrap-up and rear wrap-up carry out two-way rolling to the cloth of required rolling, first is guide piece to rolling circuit, pre-tightening apparatus, front wrap-up, second is guide piece to rolling circuit, pre-tightening apparatus, rear wrap-up, front wrap-up and rear wrap-up, two-way winder of the present utility model, adopt the version of wrap-up and rear wrap-up rolling simultaneously before the two ends of rolling lever arrange, give one period of surge time of front wrap-up, avoid front wrap-up rolling too fast, the phenomenon that the fold causing and elasticity differ, and increase rear wrap-up, also improve the efficiency of rolling.

Further, for ensureing front wrap-up and the rear wrap-up rolling cloth that can link, rolling lever is connected in frame by bearing, and rolling lever rotates taking bearing as fulcrum.

Further, between front wrap-up and pre-tightening apparatus, be also provided with tightening device, to improve the degree of uniformity of cloth of rolling.

Again further, between tightening device and rear wrap-up, be also provided with position-limited lever, big connecting rod, small rod, coiling bar, thereby realize the interlock rolling cloth of front wrap-up and rear wrap-up, and to make rear wrap-up be that front wrap-up cushions, thus the degree of uniformity of the cloth of wrap-up before ensureing.

Compared with prior art, the beneficial effects of the utility model are: two-way winder of the present utility model, adopt the version of wrap-up and rear wrap-up rolling simultaneously before the two ends of rolling lever arrange, give one period of surge time of front wrap-up, avoid front wrap-up rolling too fast, the phenomenon that the fold causing and elasticity differ, and increased rear wrap-up, also improve the efficiency of rolling.

The utility model has increased a wrap-up, form the device of two-way rolling cloth, avoid front wrap-up rolling too fast, the phenomenon that the fold causing and elasticity differ, and increased rear wrap-up, also improve the efficiency of rolling, and having ensured the degree of uniformity of the cloth of rolling, the generation of elasticity and corrugationless phenomenon, has improved the quality of the cloth of coating, avoid waste, reduced the generation of fraction defect.

Brief description of the drawings

Fig. 1 is the front view of the two-way winder of a kind of coating machine.

Detailed description of the invention

In order to deepen, to understanding of the present utility model, below in conjunction with drawings and Examples, the utility model to be further illustrated, this embodiment, only for explaining the utility model, does not form and limits protection domain of the present utility model.

As shown in Figure 1, the two-way winder of a kind of coating machine, comprise frame 1, and be connected to from left to right the rolling lever 8 in frame 1 in turn, pre-tightening apparatus 11, guide piece 14, the rolling from right to left of the cloth of required rolling, rolling lever 8 two ends, left and right are provided with respectively wrap-up 4 and rear wrap-up 9, wrap-up 4 and rear wrap-up 9 carry out two-way rolling to the cloth of required rolling, first is guide piece 14 to rolling circuit, pre-tightening apparatus 11, front wrap-up 4, second is guide piece 14 to rolling circuit, pre-tightening apparatus 11, rear wrap-up 9, front wrap-up 4 and rear wrap-up 9, two-way winder of the present utility model, adopt the version of wrap-up 4 and rear wrap-up 9 rollings simultaneously before the two ends of rolling lever 8 arrange, give 4 one periods of surge time of front wrap-up, avoid front wrap-up 4 rollings too fast, the phenomenon that the fold causing and elasticity differ, and increase rear wrap-up 9, also improve the efficiency of rolling.

Secondly, for ensureing front wrap-up 4 and the rear wrap-up 9 rolling cloth that can link, rolling lever 8 is connected in frame 1 by bearing 12, and rolling lever 8 rotates taking bearing 12 as fulcrum.

Again, between front wrap-up 4 and pre-tightening apparatus 11, be also provided with tightening device 2, to improve the degree of uniformity of cloth of rolling.

Again, between tightening device 2 and rear wrap-up 9, be also provided with position-limited lever 10, big connecting rod 5, small rod 6, coiling bar 7, thereby realize the interlock rolling cloth of front wrap-up 4 and rear wrap-up 9, and rear wrap-up 9 is cushioned for front wrap-up 4, thereby the degree of uniformity of the cloth of wrap-up before ensureing.

The utility model has increased a wrap-up, form the device of two-way rolling cloth, avoid front wrap-up 4 rollings too fast, the phenomenon that the fold causing and elasticity differ, and increased rear wrap-up 9, also improve the efficiency of rolling, and having ensured the degree of uniformity of the cloth of rolling, the generation of elasticity and corrugationless phenomenon, has improved the quality of the cloth of coating, avoid waste, reduced the generation of fraction defect.

What embodiment of the present utility model announced is preferred embodiment; but be not limited to this; those of ordinary skill in the art; very easily according to above-described embodiment; understand spirit of the present utility model; and make different amplifications and variation, but only otherwise depart from spirit of the present utility model, all in protection domain of the present utility model.
