Description
The present invention relates to a kind of at the part of appliance that is coated with air hole processing on the PE class film shape carrier of adhesive.
The medical personnel knows, on the PE class medical film adhesive tape, the aperture that is used to breathe freely with countless queueing disciplines, porose medical adhesive tape can make the surface of a wound ventilative in use, quickens Wound healing, alleviate patient's misery, and adhesive tape can be longitudinally or transversely arranged pore, tears into neat strip arbitrarily, and is easy to use.Being seen in the market PE class medical adhesive tape, import and two kinds of homemade products are arranged, the imported product quality is more excellent, its characteristics are to be distributed with on the full wafer adhesive tape vertically and horizontal regularly arranged tiny air-vent, the spacing of the Kong Xinyu hole heart only has 1mm, the diameter in hole is 0.05-0.2mm, but price is high.Homemade PE class adhesive tape, because punch device does not pass a test, quality is not as imported product.General perforated roll is to get on the bus on the metal tube surface or mill out the pointed tooth of spacing 1mm, during use, earlier to the metallic roll heating, then the film adhesive band is carried out the roll extrusion punching.But its effect is bad, and major defect has two aspects: one, owing to be that difficulty is bigger at the integral body on metal tube surface processing serration, the distance of crown is 1mm only, is difficult to accomplish not pawl, broken teeth not in the processing.When two, roll body uses, must treat just can carry out when the crown temperature improves the roll extrusion punching from roll centre or roll surface heating earlier.But because crown and tooth root, promptly roll surface is whole metal material, when the crown temperature is high, roll surface temperature is high equally, even higher, during like this to the adhesive tape roll extrusion, the position that needs on the adhesive tape to punch and do not need to punch is heated equally, and same the generation is out of shape, even influences the quality of adhesive.If for indeformable and turn down temperature, though then often 1 hole was arranged adding when man-hour, crown passed adhesive tape, the temperature deficiency can not make membrane pores around shrink, after crown leaves film, the hole of being punched is closed immediately again, and majority becomes blind hole, influences the result of use of adhesive tape greatly.Because parts crucial on the PE medical film adhesive tape air hole processing equipment are perforated rolls, the about 150mm of diameter, the perforated roll of length 1200mm, need ten thousand dollars of 50-60 abroad, the developed country that some technology reaches a standard is also bottling up at present, is not sold to China.So, aspect capital operation, just use PE class adhesive tape, and only this item, every year also must the huge foreign exchange of cost.
The objective of the invention is to overcome above-mentioned weak point of the prior art, and provide the heating of a kind of crown and roll surface is not warm or low-grade fever, can improve the perforated roll of the PE class medical film adhesive tape air-vent of air-vent crudy.
Purpose of the present invention can reach by following measure: be with many round metal gear pieces on a metal hollow axle, between per two round metal gear pieces, also accompany a heat shield, a heating, for example electrical bar or electrothermal tube are pierced in the hollow shaft center.
Purpose of the present invention can also reach by following measure: the metal hollow axle can be a steel pipe, can equidistantly have 3 to 4 rectangular channels that mill the poling wall longitudinally on its surface, 3 or 4 rectangular channels on hollow shaft, have an end stay one section not open-minded, head for hollow shaft, it also can be the hollow shaft of not establishing rectangular channel, a semicircle longitudinally little shallow slot is arranged on its surface, the round metal gear piece can be the charcoal steel sheet, the equidistant needle-like pointed tooth of arranging in its circumferential distribution, the head of pointed tooth is the crown of four sides triangle cone, the bottom is the square column type tooth body that equals long 2 to 3 times of crown, can there be 3 to 4 rectangle boss at the center of knuckle-tooth sheet, boss is corresponding with the rectangular channel position on the hollow shaft, both width are identical, the length of boss slightly is longer than the pipe thickness of hollow shaft, and knuckle-tooth sheet center can not have boss yet, has only a semicircle small embossment.Heat shield can be an asbestos board, is the hollow annular thin plate, and the outside diameter is between the crown diameter and root diameter of knuckle-tooth sheet, and diameter of bore equals the external diameter of hollow shaft.In having the hollow shaft of rectangular channel, insert electrical bar, in the hollow shaft of not establishing rectangular channel, insert electrothermal tube.At the two ends of hollow shaft gland and nut are arranged.There is joint axis at two ends at the hollow shaft that has rectangular channel.On electrothermal tube, be with 1 to 2 electric slip ring.
The present invention has following advantage compared to existing technology: 1. owing to be decomposed into circle sheet processing crown, simplify greatly technically, can avoid the pawl, the broken teeth problem that are prone in the whole roller processing.2. between the knuckle-tooth sheet, accompany a slice heat-barrier material, flake asbestos for example, the diameter of heat shield is in the crown diameter of knuckle-tooth sheet between the root diameter, so the effect of heat shield is that the temperature of the temperature of crown and tooth root is cut off, make whole roll surface only expose crown, tooth root does not appear, penetrate the film adhesive tape when crown and make the limit, hole be heated, be out of shape, shrink and when forming complete hole, the position that adhesive tape need not punch, just contact with the roll surface that heat shield is formed, no heat or low-grade fever can not make adhesive tape deform, and have guaranteed the quality of adhesive tape.3. because the roll body process technology is simple, significantly reduce waste product, efficient improves, and can cut down finished cost significantly.Perforated roll in use as find that crown damages, maintenance, changes all more convenient, as long as adjust the knuckle-tooth sheet, unlikely whole roll body calcellation.5. the distance of the size of pointed tooth, between cog can be along with the thickness of adjusting the knuckle-tooth sheet, and the thickness of tooth pitch and heat shield and changing uses on other film that need punch to adapt to, and becomes multi-functional punch device.
