Description

A kind of banding machine hemisection device

Technical field

The utility model relates to banding machine, is specifically related to a kind of banding machine hemisection device.

Background technology

Banding machine is one of main corollary equipment of cross cutting industry, is mainly used in the flexible material of cutting view picture.

General common banding machine, as shown in Figure 1, it mainly is to be provided with a dispensing shaft A and collecting shaft B more than a group in board, and between dispensing shaft A and collecting shaft B, establishes one group of axle drive shaft C, one group and draw axis of guide D and one group of cutting mechanism E.

Wherein, cutting mechanism E is made up of the circular cut-off knife more than a group, and every group of circular cut-off knife is made up of upper slitter and the seamless intersection of following cutter respectively upper slitter E1 and following cutter E2.Material passes traction axis of guide D by dispensing shaft A and drives the coiled material that is divided into specific fabric width more than two through cut-off knife E1, E2 up and down by axle drive shaft C, again by collecting shaft B rolling one by one.

Above-mentioned banding machine is mainly used in the cutting fully of material, comprises monolayer material, and like parting paper, mould release membrance etc., double layer material is like double faced adhesive tape, label paper etc.Yet, occur getting more and more and need double faced adhesive tape, label paper be separated the hemisection demand of cutting with parting paper along with the development of cross cutting industry.Traditional banding machine can not satisfy this demand fully.

The utility model content

The purpose of the utility model is to provide a kind of hemisection tape divider; When it can solve other materials such as double faced adhesive tape or label paper and combines with parting paper; The hemisection tape divider can satisfy whole cut-outs of other materials such as double faced adhesive tape or label paper, and the hemisection demand that parting paper is not cut off.

A kind of banding machine hemisection device; Comprise dispensing shaft and collecting shaft; Axle drive shaft, the traction axis of guide and cutting mechanism are set between dispensing shaft and the collecting shaft; Described cutting mechanism is made up of adjustable depth of cut air knife and retainer axle, and described retainer axle is fixed on the frame, and adjustable depth of cut air knife is above the retainer axle.

Described adjustable depth of cut air knife comprises dise knife, movable handle of a knife, dowel bolt, atmospheric pressure cavity and tracheae; Described dise knife is arranged on an end of movable handle of a knife, and dowel bolt is arranged on the other end of movable handle of a knife; Movable handle of a knife links to each other with atmospheric pressure cavity, and atmospheric pressure cavity is connected with tracheae.

The utility model keeps the banding machine known structure of prior art basically, by the air knife and the former circular cut-off knife formula cutting mechanism up and down of retainer axle replacement of free adjustment depth of cut.The retainer axle is arranged between axle drive shaft and the collecting shaft.One group of air knife is set on this retainer axle, and this air knife is circular cut-off knife.Above-mentioned air knife can be realized the degree of depth of feed through the length of regulating dowel bolt; To treat that by circular air knife the branch strip material is pressed on the retainer axle during itemize; The degree of depth of regulating feed through the dowel bolt of regulating full cutting knife and hemisection cutter respectively; Thereby realize material is carried out the cutting of different depth, accomplish and cut entirely and the hemisection function.

Beneficial effect:

(1) this apparatus structure is simple, Installation and Debugging convenient;

(2) this device can be according to the difference of material, regulates air pressure, makes the requirement that air knife is accomplished hemisection or cut entirely;

(3) this device has substituted script by the cutting die method for processing, has improved process velocity greatly, has saved a large amount of cutting die costs.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the present invention is further described:

Embodiment 1

Extremely shown in Figure 4 like Fig. 1; A kind of banding machine hemisection device; Comprise dispensing shaft A and collecting shaft B, axle drive shaft C, traction axis of guide D and cutting mechanism G, F are set between dispensing shaft A and the collecting shaft B, described cutting mechanism is made up of adjustable depth of cut air knife G and retainer axle F; Described retainer axle is fixed on the frame, and adjustable depth of cut air knife G is above retainer axle F.

Embodiment 2

To shown in Figure 4, a kind of banding machine hemisection device is provided with a retainer axle F between axle drive shaft C and collecting shaft B like Fig. 1.Above-mentioned retainer axle F is cylindric metal shaft, is fixed on the frame.Above-mentioned retainer axle F requires radial runout between 0.001 ~ 0.005 mm, and roughness of surface is at Ra 0.1 ~ 0.5 μ m, and hardness is between HRC 60 ~ 70.Guarantee that retainer axle and dise knife can keep accurately coincideing when high-speed operation.

One group of circular air knife G is set on this retainer axle.Above-mentioned air knife G comprises dise knife 1, movable handle of a knife 2, dowel bolt 3, atmospheric pressure cavity 4, tracheae 5 and forms.Dise knife 1 and piston 6 are installed in an end of movable handle of a knife 2, and the other end is provided with dowel bolt 3.Movable handle of a knife 2 links to each other with atmospheric pressure cavity 4, and piston 6 and dise knife 1 are installed in the atmospheric pressure cavity 4, and atmospheric pressure cavity 4 connects tracheae 5.

Tracheae 5 is connected on the Air compressor, and the air pressure that produces in the atmospheric pressure cavity 4 promotes piston drive activity handle of a knife 2 to the fixed position, and this moment just can be through regulating the action radius that dowel bolt 3 is regulated movable handle of a knife 2.Treat that the branch strip material passes the retainer axle by the axle drive shaft drive, is pressed in circular air knife G on branch strip material and the retainer axle F.Realize the degree of depth of feed through regulating dowel bolt 3, just can realize material is carried out the cutting of different depth, accomplish hemisection and cut function entirely with this.
