Abstract
The utility model relates to a polyethylene valve pocket bottom fusion mould, which includes a die mould(1) and top mould(2) corresponded in up-and-down or left-and-right. A metal mould(3) is arranged at the bottom of die mould(1); a far infrared heat pipe(4) or platen heater or heater strip or electric heating chip is arranged on the side of the mould(3); a metal strip(5) is connected with the outside of the mould(3); an elastic plane panel(6) is arranged on the working surface of the top mould(2); a mains connector(7) connected with the heat pipe(4) is arranged on the side of the die mould(1). The fusion mould structure is simple, safety, and reliable, which can realize the large area fusion at the monment, and can make the fusion surface be firmly and smooth, heat-resistance and cold-resistance; and can increase the service life of the valve pocket, and ensure that the packing of the valve pocket is in good conditon.
Description
Affiliated technical field
The utility model relates to a kind of welding processing mold, specifically a kind of welding mould at the bottom of the welding polyethylene valve port bag bag.
Background technology
At present, polyethylene packaging bag back cover mostly is to adopt adhesive to paste at the bottom of the broadband, and fastness is poor, easily inharmonious, aging, aliquation.Also have adopt common fusion splicer to the polyethylene packaging bag at the bottom of at the bottom of carry out welding, as electric iron, but its welding area is little, thermal break-through power is not strong, once can only the welding layer 2-3, fusion temp is difficult for grasping, weld is uneven, and draws trace darker; And for example sealing machine is generally the straight line welding, can not disposable large tracts of land welding, at most also can only welding 3-4 layer, and weld easily open split, tearing notch.Existing fusion splicer can not be realized the disposable welding at the bottom of the broadband more than 10 layers of polyethylene valve port bag.
Summary of the invention
Insecure in order to solve the polyethylene valve port bag bag primer stick that exists in the prior art, can not realize the shortcoming of disposable smooth firm welding at the bottom of the multilayer large tracts of land Polythene Bag with fusion splicer, it is a kind of simple in structure that the utility model provides, welding is firmly smooth, thermal break-through power is strong, the welding area is big, to the welding mould of the disposable instantaneous welding in the polyethylene valve port bag multilayer polygon bag end.
The technical solution of the utility model is: mainly comprise up and down or about corresponding pressing mold and backform, the bottom of pressing mold is provided with metal form, the template medial surface is provided with far-infrared heating tube or electric hot plate or heating wire or electrothermal chip, be connected with the metal pattern bar on the lateral surface of template, the working face of backform is provided with the elastic linear plate, and the pressing mold side is provided with the power connection that is connected with heating tube.
Far-infrared heating tube on the template medial surface is one or more horizontal or vertical evenly distributed shape; The metal pattern bar that connects on the template lateral surface is many laterally or vertically or the random geometry of criss-cross arrangement or irregularly shaped.
The beneficial effects of the utility model are: this welding mould is simple in structure, safe and reliable, constant temperature and outside under the effect of impulse power, utilize far infrared to penetrate metal and nonmetallic principle except that aluminium, to carrying out disposable large tracts of land welding of moment at the bottom of the polyethylene valve port bag bag more than 10 layers, make face of weld firm smooth, heat resistanceheat resistant is cold-resistant, prolong the service life of valve port bag, guarantee that the intact nothing of valve port bag packing material is let out.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
In Fig. 1, pressing mold 1, backform 2, metal form 3, far-infrared heating tube 4, metal pattern bar 5, elastic linear plate 6, power connection 7.
The specific embodiment
The utility model will be further described below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, welding mould mainly comprises corresponding up and down pressing mold 1 and backform 2 at the bottom of the polyethylene valve port bag bag, pressing mold 1 bottom is fast and the even metal template 3 of conducting heat, the evenly distributed far-infrared heating tube of 1-6 root 4 is installed on metal form 3 medial surfaces, on metal form 3 lateral surfaces, be connected with many mould bars 5 as copper bar or aluminum strip, mould bar 5 quantity and spread geometry according to valve port bag bag at the bottom of shape, the size of required face of weld decide.The working face of backform 2 is provided with elastic linear plate 6, and pressing mold 1 side is provided with the power connection 7 that is connected with heating tube 4.When at the bottom of the welding one valve port bag bag, be placed on the silica gel plate 6 of backform 2 at the bottom of a bag of valve port bag, and on the bag bottom surface, cover an one deck and the onesize lining of bag floor space, the welding mould that is installed on the forcing press is connected power supply, switched on about 10 minutes, and when treating mould temperature, depressed pressing mold 1 to 160-200 °, with the welding that realizes the several seconds at the bottom of the valve port bag bag on the backform 2, so at the bottom of one bag in the good valve port bag of welding; With loading onto valve port at the bottom of another bag of valve port bag on one side, cover one deck lining again, go into liner plate from valve port to bag end liner, place on the silica gel plate 6 on backform 2 working faces, depress pressing mold 1, the welding at the bottom of another bag of realization valve port bag.
