Description

Hot-melting skin cutting device for EPE forming block

Technical Field

The utility model belongs to the foam plastic recycle equipment field, specifically speaking are a cutting device for EPE becomes profiled block.

Background

The foam plastic is taken as a recyclable material, and is usually crushed and then extruded or melted during recycling, so that the discharged material is convenient to transport, otherwise, the foam plastic occupies a transport volume due to low density and light weight.

In order to prevent the volume of a molded block from rebounding after compression in a conventional foam compressor for processing EPE (polyethylene foam), the surface of the molded block needs to be ironed, and a PE hot melt layer with the thickness of 3-5 mm is formed on the surface of the molded block. But at this moment the epidermis is cut off by the shaping piece that the hot melt scalds at the in-process very difficult cutting off, if adopt present ordinary hydraulic pressure cutter to cut off, need about 30kw power hydraulic press can drive the cutter and cut off the shaping piece, the too big increase that causes production facility cost, and it can only be from the top to the next direction to directly adopt hydraulic press cutter to cut off, the incision of shaping piece left and right sides is not cut off, but is torn, just so make the section of shaping piece very unevenness after the cutter directly cuts off, the section also can be because of cutting off the too big deformation of holding down force, form unevenness's irregular face, be unfavorable for subsequent storage and stack. If manual material cutting is adopted, time and labor are wasted.

Disclosure of Invention

The utility model aims at providing a hot melt epidermis cutting device for EPE becomes the briquetting, solves the briquetting epidermis of the ejection of compact of current compression EPE machine and is difficult to cut off or cut off the problem that the effect is not good to the not enough of above-mentioned prior art exactly.

The utility model adopts the technical scheme as follows:

a hot-melting skin cutting device for EPE forming blocks is characterized by comprising a first discharging groove and a second discharging groove for discharging the compressed EPE forming blocks, wherein a section of interval is reserved at the joint of the first discharging groove and the second discharging groove, two groups of vertical and horizontal racks are arranged at the interval, two groups of knife rests are respectively arranged in the two groups of racks, one group of knife rest is positioned at the two horizontal sides of the discharging direction of the EPE forming blocks, the other group of knife rest is positioned at the two vertical sides of the discharging direction of the EPE forming blocks, and the two groups of knife rests are respectively driven by cylinders correspondingly arranged on the outer walls of the two groups of racks; the knife rests are all provided with a knife blade.

The blade edge part is V-shaped.

Guide rails are arranged on the left outer side and the right outer side of the knife rest in the vertical rack or on the upper outer side and the lower outer side of the knife rest in the transverse rack.

The guide rail slides back and forth on a sliding block arranged on the inner side wall of the rack during operation.

The inner diameters of the notches of the first discharging groove and the second discharging groove are consistent.

The beneficial effects of the utility model are that:

according to the EPE block size of the ejection of compact, knife rest reasonable in design through the fixed knife rest of guide rail frame, and cylinder drive knife rest makes the sword on the knife rest cut off EPE shaping piece surface scald the part, cuts the ejection of compact piece behind the epidermis at subsequent cutting-off process, only needs the hydraulic press of very little power just can cut off the ejection of compact piece, practices thrift equipment cost greatly to the cut surface is very level and smooth, convenient transportation.

1. The cutting device is driven by a cylinder, is clean and efficient, has a cutting speed block, and can well cut the hot surface of the EPE forming block;

2. the guide rail sliding block is adopted, so that the moving track of the cutter is stable, and the cutter blade cannot be broken in the cutting process;

3, a second discharge chute is arranged, so that the EPE forming block cannot move in the cutting process, and the blade can accurately cut the hot surface in the cutting process;

4. the blade is rational in infrastructure, and when the initial cutting material, the lifting surface area progressively increases, can be very smooth cut off EPE shaping piece surface, can not block or make the blade damage.

In the figure, 1, cylinder; 2. a guide rail; 3. a tool holder; 4. a slider; 5. a blade; 6. a second discharge chute; 7. a frame; 8. a first discharge chute.

Detailed Description

The invention will be further described with reference to the accompanying drawings:

as shown in fig. 1, the utility model discloses a first blown down tank 8 and the second blown down tank 6 of the EPE shaping piece ejection of compact after supplying the warp compression, one section interval is left to the junction of first blown down tank 8 and second blown down tank 6, is equipped with vertical and horizontal two sets of frames 7 in this interval department, all install two sets of knife rests 3 in two sets of frames 7, wherein a set of knife rest 3 is in the horizontal both sides of EPE shaping piece ejection of compact direction, and another set of knife rest 3 is in the vertical both sides of EPE shaping piece ejection of compact direction, and these two sets of knife rests 3 are driven by corresponding cylinder 1 of installing on two sets of frames 7 outer walls separately. The guide rails 2 are arranged on the left outer side and the right outer side of the knife rest 3 in the vertical rack 7 or on the upper outer side and the lower outer side of the knife rest 3 in the transverse rack 7, and the slide blocks 4 arranged on the inner side wall of the rack 7 slide back and forth when the guide rails 2 work. The blade 5 is arranged on each knife rest 3, and the outer surface layer of the EPE discharging block can be cut by the hot skin through the two groups of knife rests 3 and the corresponding blades 5, so that the EPE discharging block can be cut off only by a hydraulic press with small power in the subsequent cutting process, and the EPE discharging block does not need to exceed 3KW generally.

The utility model discloses its edge of a knife part of blade 5 in the above-mentioned structure is the V-arrangement, and when the initial cutting material like this, lifting surface progressively increases, can be very smooth cut off EPE one-tenth shape piece surface, can not block and pause or make the sword damage. When the blade 5 returns to the initial position, the cutting edge on the other side edge can perform second cutting on the surface skin of the discharging block, so that the surface cutting effect is ensured.

The utility model discloses the notch internal diameter size of first blown down tank 8 and second blown down tank 6 keeps unanimous, and the effect of second blown down tank 6 makes the play material piece be in leveling the position carrying out the epidermis cutting, and the position remains stable relatively and can not rock, can make cutting effect better like this.

The working process of the utility model is as follows:

EPE ejection of compact piece skin is scalded the back, passes through first blown down tank 8 earlier, reachs second blown down tank 6 again, reaches to cut off length after, ejection of compact piece stop operation, and two sets of cylinders 1 drive knife rest 3 and blade 5 everywhere respectively go on, and guide rail 2 on the knife rest 3 stably moves ahead under slider 4's limiting displacement, makes blade 5 carry out vertical both sides face cutting to ejection of compact piece, or the cutting of the upper and lower both sides face of ejection of compact piece. The single group of blades 5 are brought back by the tool rest 3 after reaching the final working position, the surface of the discharging block is subjected to supplementary cutting again, the surface cutting work of the section of the discharging block is completed, the discharging block continues to discharge materials and moves forward, and the hot melting surface cutting process is repeated after the discharging block reaches another length to be cut.

Other parts which are not described in the present invention are the same as those in the prior art.
