Abstract
The utility model relates to a cloth feeding device on a breaker, which is characterized in that axis lines of a cloth feeding wheel and a cloth pressing wheel on the two sides of a cloth supporting frame leans to the moving direction of cloth, the axis lines of the cloth feeding wheel and the cloth pressing wheel and a plumb line form an acute angle theta, and the value of the acute angle theta is between 5 degrees and 20 degrees. Compared with the prior art, the cloth feeding device has the beneficial effects that the cloth feeding device has the function of feeding cloth, also has the rectification function, does not need to arrange an edge guide on the breaker, and greatly saves cost.
Description
Technical field
The utility model relates to breaker, particularly a kind of cloth-feeding device on the breaker.
Background technology
Breaker generally is made up of six breaking devices and seven cloth-feeding devices, and at breaking device of per two cloth-feeding device intermediate arrangement, it can carry out the stoking operation to linings such as superfine fiber chemical leather, islands-in-sea type fibre synthetic leather, PU leather.
In the prior art, the cloth-feeding device of breaker as shown in Figure 1 and Figure 2, at internal stent, three work feeds wheel be arranged in width holder about and center of top, be driving wheel, cloth is rolled into semi-barrel shape and rides on the width holder, three compress wheels are arranged in the inside of width holder, and cloth and work feed wheel are compressed, and the work feed wheel rotates, frictional force to cloth generation horizontal direction just can make the cloth along continuous straight runs move forward.
In machine running process, owing to of the effect of breaking device to cloth, cloth meeting sideslip, promptly selvedge can shrink to the centre.In order to address this problem, existing breaker, all installed edge guide additional on the both sides of breaking device cloth is rectified a deviation, a breaker of being made up of six breaking devices and seven cloth-feeding devices will be installed 12 pairs of edge guides, has improved the manufacturing cost of machine greatly.
Summary of the invention
Technical problem to be solved in the utility model provides the cloth-feeding device in a kind of breaker, makes its existing work feed function, and deviation-correcting function is arranged again.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
A kind of cloth-feeding device, comprise work feed wheel, compress wheel and support, it is characterized in that: the work feed wheel of width holder both sides and the axis of compress wheel tilt to the traffic direction of cloth, the axis and the plumb line of this work feed wheel and compress wheel acutangulate θ, the value of acute angle theta is between 5～20 degree, and wherein the value of acute angle theta equals 10 degree for most preferably.
Described cloth-feeding device also comprises pull bar, and the one end is provided with circular hole, and hinged with support, the other end is provided with slotted hole, and is connected with bolt between the frame, establishes circular hole in the support bottom simultaneously, and hinged with frame, the size that can regulate the θ angle like this adapts to different clothes.
The θ angle is unlikely to excessive when making vertically downward component Fv enough big, and the length L of the work feed wheel of width holder both sides is between 80～200mm, and the length of corresponding compress wheel equates with it, and wherein the L value equals 160mm for most preferably.
Compared with prior art, the beneficial effects of the utility model are: existing work feed function, deviation-correcting function is arranged again, and no longer need to install edge guide on the breaker, saved cost greatly.

The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing:
As Fig. 3, shown in Figure 4, a kind of cloth-feeding device, comprise work feed wheel 1, compress wheel 2 and support 3, the work feed wheel 1 of width holder 4 both sides and the axis of compress wheel 2 tilt to the traffic direction of cloth 7, the axis and the plumb line of this work feed wheel 1 and compress wheel 2 acutangulate θ, like this, the work feed frictional force F direction that the work feed wheel 1 of width holder 4 both sides produces becomes the θ angle with the traffic direction H of cloth 7, as shown in Figure 3, this frictional force F can be decomposed into a horizontal component Fh and a component Fv vertically downward, horizontal component Fh moves cloth 7 along continuous straight runs forward, component Fv vertically downward prevents the cloth sideslip, the value of acute angle theta is between 5～20 degree, and as best angle, the value of acute angle theta equals 10 degree in the present embodiment.
Circular hole is established in bottom at support 3, and is hinged with frame 6, and an end of pull bar 5 is provided with circular hole, and hinged with support 3, the other end is provided with slotted hole, and is connected with bolt between the frame 6, can regulate the size at θ angle like this.Different clothes are different with the coefficient of friction between the work feed wheel 1, and resulting component Fv vertically downward is also different, and the big I of regulating the θ angle makes this cloth-feeding device can adapt to different clothes.
The θ angle is unlikely to excessive when making vertically downward component Fv enough big, and the length L of the work feed wheel 1 of width holder 4 both sides is between 80～200mm, and the length of corresponding compress wheel 2 equates that with it as optimum length, the L value equals 160mm in the present embodiment.
