Abstract

An improved embossing roller relates to the plastic product surface molding mechanic technical field. It is especially a processing tool for printing flower pictures on leather and plastic products. The technical scheme is as follows: embossing roller comprised of air cell, metal button roller, and flower roller is set on frame. Cylinder-type air cell is filled in metal button roller covered with flower roller. Air holes leading to flower roller are set among metal button rollers. Air pumping channel leading to the outside of frame are also set between air cell and metal button roller. Flower roller is made of ventilate materials and can process plastic flowers of various thickness. Since the processed parts absorbed with negative pressure, the flower embossed has a strong feeling of third dimension. Finished artificial leaders such as PVC will have even bigger difference, and the thickness after embossing in the way of negative pressure is 0.05-0.20mm bigger than before, thus lowering production cost. Therefore, the product has a bright market prospect.

Description

A kind of modified form knurling rolls

Technical field:

The utility model relates to surface of plastic product forming machine technical field, refers to a kind of machining tool of suppressing floral designs on artificial leather, plasthetics especially.

Background technology:

Plastic cement products generally can to increase its surperficial aesthetic feeling, produce diversified product at the various decorative patterns of its surface forming, with the desire that attracts the consumer to buy after machining; Or wait other industrial use to increase the antifriction damage at the various decorative patterns of surface forming, and the operation principle of various plastic body surface detail building mortions all is to adopt rubber rollers and knurling rolls will need the plastic cement surface roll compacting of moulding to go out required decorative pattern to the form of rolling, that is adopts the mode of malleation.The various required floral designs of roll forming on cylinder surface, in order to guarantee knurling rolls operate as normal at a lower temperature, also need the cooling duct is set on knurling rolls, thereby this knurling rolls manufacturing process complexity not only, and the cost height, can not satisfy the needs of production; And; in process of manufacture; go out if the plastic cement products thickness of processing is when being lower than a certain size (as less than 0.2 millimeter) through regular meeting; rubber rollers and knurling rolls just can't be at its surface forming decorative patterns; trace it to its cause; then be owing to due to the reasons such as decorative pattern of spacing between rubber rollers and the knurling rolls and knurling rolls surface forming, bring many inconvenience to factory.

Summary of the invention:

The purpose of this utility model is to overcome above-mentioned weak point of the prior art, and a kind of modified form knurling rolls are provided.

The utility model is achieved by the following technical solution: the utility model comprises that adjustable shelf is located at the knurling rolls on the frame, knurling rolls are made up of air bag, tie insert roller and patterned roll, the balloon tamponade of tubular coats the line roller of blossoming outside the tie insert roller among the tie insert roller.Be provided with the air-vent that leads to patterned roll between the tie insert roller, between air bag and tie insert roller, the bleed-off passage that leads to outside the frame also arranged.Patterned roll is that the breathable material is one-body molded, and ventilative patterned roll is sand grains and binding agent hot briquetting.

The utlity model has advantage of simple structure, can process the decorative pattern of the plastic body of all thickness, and process owing to hold work piece by negative pressure, third dimension of patterns on the work piece is strong, can make the finished product difference of artificial leathers such as PVC bigger, and the thickness of the forward and backward difference between the two of malleation mode embossing minimizing 0.05-0.20 millimeter, and the thickness of the forward and backward difference between the two of negative pressure mode embossing increases the 0.05-0.20 millimeter, reduce production cost, had extensive market prospects.

Accompanying drawing 4 is the utility model processing schematic diagram

The specific embodiment:

See accompanying drawing 1,2,3,4, the utility model comprises that adjustable shelf is located at the knurling rolls 3 on the frame 7, knurling rolls 3 are made up of air bag 1, tie insert roller 2 and patterned roll 31, and the air bag 1 of tubular is packed among the tie insert roller 2, coat the line roller 31 of blossoming outside, tie insert roller 2.2 on tie insert roller is provided with the air-vent that leads to patterned roll 31, between air bag 1 and tie insert roller 2 bleed-off passage that leads to outside the frame 7 is also arranged.Patterned roll 31 is that the breathable material is one-body molded, and ventilative patterned roll is sand grains and binding agent hot briquetting.

When using the utility model, be packed among the tie insert roller 2 air bag 1 of tubular and inflation, the tie insert roller 2 that the fastens air bag 1 that is filled gas is filled and is tubular mutually, and the outer surface of tie insert roller 2 abuts in patterned roll 31; During decorative pattern on needing forming plastic cement body 4, plastic body 4 is under the traction of traction wheel 6, move through knurling rolls 3, and plastic body 4 before moving through knurling rolls 3 by heater 5 thermoplastics, when moving through knurling rolls 3, air extractor is by the bleed-off passage exhaust outside frame 7 between air bag 1 and the tie insert roller 2, and 2 on tie insert roller is provided with the air-vent that leads to patterned roll 31, it is air-breathing then to see through the patterned roll 31 that ventilative materials processing forms, make the outer surface of patterned roll 31 form negative pressure, the plastic body 4 that moves through on the knurling rolls 3 is adsorbed on the knurling rolls 3, and by shaping pattern.
