Abstract

The utility model provides a cloth slitting machine which comprises a panel and a novel back of a line chipping retaining circular knife. A ring groove is arranged on the circumference of a round hole at the center of the panel. The back is combined with the panel at the ring groove. In time of working, the cloth slitting machine can reduce cloth and line chippings which slip into a revolution shaft portion of the cloth slitting machine by more than 90% and even the amount of the cloth and line chippings is close to zero. The technical defect that cloth and line chippings which are raised by a blade when the cloth slitting machine works wind on a shaft and the shaft is stuck is overcome, service life of the cloth slitting machine is greatly prolonged and working efficiency of the cloth slitting machine is greatly improved.

Description

A kind of rag cutter

Technical field

The utility model relates to the textile garment field of mechanical technique, particularly a kind of rag cutter.

Background technology

Panel is fixed during rag cutter work, and the dise knife backrest is to be fixed on the rag cutter turning cylinder to run up with axle with circular knife.Its defective is: owing between dise knife backrest and the panel bar slit is arranged, the circular knife that runs up during the rag cutter fabric dividing can carry a small amount of wiring of absorption or cloth bits and enter from the slit between dise knife backrest and panel and be wound on the turning cylinder, increase along with service time, accumulating over a long period is wound into wiring on the turning cylinder and the cloth bits are more and more, how to a certain degree can can't burning out by the turning handle motor turning cylinder is stuck.

The utility model content

The utility model provides a kind of rag cutter, stuck around axle with the wiring bits that prevent rag cutter, as to improve rag cutter service life and the operating efficiency that improves rag cutter.

To achieve these goals, the utility model provides following technical scheme:

A kind of rag cutter, it comprises: panel and gear line bits dise knife backrest, the middle circular of described panel is provided with circular groove, is positioned at the groove of described panel when described gear line bits dise knife backrest and panel combination.

Preferably, the reverse side of described gear line bits dise knife backrest is provided with the second groove, and the lower end of the groove of described panel is provided with the outlet of wiring bits.

Preferably, be provided with the blade brush on the described panel.

Preferably, described the second groove is four.

By implementing above technical scheme, have following technique effect: the wiring bits that enter the turning cylinder position during work of rag cutter that the utility model provides can reduce more than percent 90, even close to zero.Solve the wiring bits around the stuck technological deficiency of axle, greatly prolonged the operating efficiency that has also greatly improved rag cutter service life of rag cutter.

The specific embodiment

In order better to understand the technical solution of the utility model, describe the embodiment that the utility model provides in detail below in conjunction with accompanying drawing.

The utility model embodiment provides a kind of rag cutter, such as Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, comprise: panel 101, described panel 101, described novel gear line bits dise knife backrest 111, circular hole 115 in the middle of the centre of described panel 101 is provided with is provided with circular groove (that is: maze trough) 113 around the described middle circular hole 115.On the circular hole 115 turning cylinder 114 is housed in the middle of this panel 101, discoidal blade 102 is housed on this turning cylinder 114.Described gear line bits dise knife backrest 111 is installed in described panel 101, and after described gear line bits dise knife backrest 111 and described panel 101 combinations, this gear line is considered dise knife backrest 111 to be worth doing and is positioned at described groove (maze trough) 113 places.

In the present embodiment, gear line bits dise knife backrest 111, blade 102 and panel 101 all are to be installed on the turning cylinder 114, this gear line bits dise knife backrest 111 is to be fixed on the turning cylinder 114 to rotate with axle with blade 102, panel 101 is fixed, and the effect of this gear line bits dise knife backrest 111 is: being used for the Resistance level bits enters axial region and supports and fixed disc shape blade 102.In the prior art, the slit between gear line bits dise knife backrest and the panel is straight line, so the wiring bits are than being easier to from entering into the moving axis position here.In the utility model, by circular groove (maze trough) is set, the circuit at slit and arrival turning cylinder position becomes broken line between novel gear line bits dise knife backrest and panel, what this technology adopted is mechanical labyrinth principle, compares with prior art like this: the probability that the wiring bits enter turning cylinder can greatly reduce than prior art.Between gear line bits dise knife backrest and discoidal blade, to form a general gap 117 that also has 3 millimeter through above improvement in addition, this gap 117 also has the wiring bits function that the consumption blade adsorbs, the wiring bits that enter this gap will need about 6 months time by normal the use probably of rag cutter around full this clearance space, but the chances are just needs about three to four months to change for the normal service life of the circular shear blade of rag cutter, (the normal meaning of using of rag cutter is: darg 8 hours, a job in month 28 days).During each replacing circular shear blade this gap 117 is cleaned out, these 117 spaces, gap have had equally again the function that consumes the wiring bits after loading onto new blade, here the wiring bits that consume are many, the wiring bits that enter the turning cylinder position just reduce, these 117 spaces, gap also have the function that minimizing wiring bits enter the turning cylinder position, the motor service life and the rag cutter operating efficiency that have further prolonged rag cutter like this.

On above-described embodiment basis, further, as shown in Figure 3, the reverse side of described gear line bits dise knife backrest 111 is provided with the second groove 115, and the groove of described panel (maze trough) lower end is provided with wiring bits outlet 112.Preferably, this second groove 115 is four, is evenly distributed in the reverse side of Novel backrest, among other embodiment, also can be more the second groove, and this second groove should not be too large, can be little strip, also can be little fan shape.This gear line bits dise knife backrest is with in the axle rotation process, and four the second grooves can be taken the wiring bits that enter between maze trough and the gear line bits dise knife backrest anchor ring out of from wiring bits outlet 112, reduced the wiring bits that enter turning cylinder with regard to another like this.

On above-described embodiment basis, further, be provided with blade brush 116 on the described panel 101.(normal operation when slight frictional force does not affect circular knife work between blade brush and the circular knife) brushes away the wiring bits that are adsorbed on the blade, reduces again the wiring bits that enter the turning cylinder position.

More than a kind of rag cutter that the utility model embodiment is provided be described in detail, for one of ordinary skill in the art, thought according to the utility model embodiment, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
