A kind of laser printer rubber roll trims degumming device
Technical field
The present invention relates to printer rubber roller and make, particularly a kind of laser printer rubber roll trims degumming device.
Background technology
Along with scientific and technological development, printer is universal already.At present most widely used on the market is ink-jet printer and laser printer, because the print speed of laser printer is fast, individual print cost low and print after the advantages such as the holding time is long, the market prospects of laser printer have surmounted ink-jet printer greatly, and the trend that replaces ink-jet printer is arranged even greatly.The consumptive material of laser printer is mainly developer roll, carbon dust and charging roller.Rubber roll demand for laser printer on market is very big.While manufacturing various semiconductive rubber roll, on the surface of plug, wrap the glue-line that one deck special substance produces, then the glue-line two ends are trimmed.In trimming step, be generally first at place, fixed position, glue-line two ends, to cut in advance by equipment, the two ends glue-line after cutting can not drop, and needs the glue-line that manually two ends are cut open to pull out, this process has seriously restricted the efficiency of whole production, affects the performance of enterprises.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind of laser printer rubber roll two ends and partly trim rear plucking device, by machinery, replaced manually, enhancing productivity.
The present invention is achieved through the following technical solutions:
A kind of laser printer rubber roll trims degumming device, and bag is put the horizontal bearing stage of rubber roll, is respectively equipped with the degumming device moved back and forth at the bearing stage two ends, and the axial line of the direction of motion of described degumming device and bearing stage upper glue roller is at same straight line.
Described degumming device is provided with guide rail, and by air cylinder driven.
Described degumming device is the knife rest that is provided with blade, and described blade is located at a side of closing on bearing stage.
At least the blade back on a knife rest is provided with stopping means, and described stopping means is L shaped, and its horizontal component is provided with the bar shaped bolt hole, is bolted on knife rest.
Preferably, described blade is provided with parallel relative blade, and the distance between described blade is greater than the diameter of rubber roll plug, and is less than the overall diameter of rubber roll glue-line.
As a modification of the present invention, described bearing stage top is provided with the rubber roll hold down gag.
Preferably, described hold down gag is that lower surface is the bar blocks on plane, the middle part that at least covers rubber roll of bar blocks.
As the present invention, further improve, described bearing stage is provided with the rubber roll storage tank of level.
Preferably, described storage tank upper surface is provided with one deck rubber.
Beneficial effect of the present invention:
It is artificial that the present invention uses machinery to replace; in the past by manually the unnecessary glue-line in rubber roll two ends after trimming being pulled out; at first be the inefficiency of manually pulling out; secondly, artificial in the process of pulling out, usually can hold the rubber roll middle part; and the still typing fully in this course of the glue-line of rubber roll; therefore the workman is when putting forth one's strength and pulling out, and probably can cause the glue-line distortion in the middle of rubber roll, causes defect rate to increase.Therefore, the present invention has not only improved production efficiency, has saved artificial input, and has guaranteed the yield rate of product.

The specific embodiment
As shown in Figure 1, bag of the present invention is put the horizontal bearing stage 1 of rubber roll, is respectively equipped with the degumming device moved back and forth at the two ends of bearing stage 1, and the axial line of the direction of motion of degumming device and bearing stage 1 upper glue roller 12 is at same straight line.
Be provided with the storage tank 11 of the rubber roll 12 of level at bearing stage 1; storage tank 11 inner surfaces also post one deck rubber (not shown), and pasting one deck rubber is in order to protect the rubber roll surface, prevents from being scratched; certainly being not limited to rubber, can be also other materials soft such as cotton, foam etc.
In the present embodiment, degumming device is the knife rest 2 that is provided with blade 3, and knife rest 2 is provided with guide rail 4, and connects cylinder and driven by cylinder 13 by push rod 5.
In conjunction with Fig. 2 and Fig. 3, blade 3 is located on knife rest 2 side of closing on bearing stage 1, and blade 3 back of a knife rest 2 are provided with stopping means 6 at least therein, and stopping means 6 is L shaped, and its horizontal component is provided with bar shaped bolt hole 7, by bolt 8, is fixed on knife rest 2.
Blade 3 is provided with parallel relative blade 9, distance between blade 9 is greater than the diameter of rubber roll 12 plugs, and be less than the overall diameter of rubber roll 12 glue-lines, rubber roll 12 is in a upper manufacturing process, the two ends glue-line has been cut out gap, therefore after blade 9 is cut along joint-cutting, when knife rest 2 moves to both sides, just the two ends glue-line is pulled out.
As a modification of the present invention, be provided with rubber roll 12 hold down gags 10 above bearing stage 1, hold down gag 10 is promoted to move downward by cylinder 13, in the present embodiment, hold down gag 10 is the bar blocks that lower surface is plane, and the size of bar blocks at least covers the middle part of rubber roll 12.Bar blocks lower surface at hold down gag 10 also can be provided with the flexible materials such as rubber or cotton, and the protection rubber roll prevents from scratching.
