Problems solved by technology

This method can achieve the strength required for bonding, but the existence of the adhesive strip increases the thickness of the bonding part, which affects the stability of winding in the subsequent process, makes winding uneven, and affects the appearance of the product.

Embodiment Construction

[0030] see first figure 1 , a kind of laser bonder with water spray belt sheet provided by the present invention, comprises workbench, support, laser gun, guide wheel, pressure roller, wherein support 3 and workbench 1 are connected as a whole, and laser gun 4 is fixed on On the support 3, the two pressure rollers 9 are parallel to each other, close to each other, and rotate in opposite directions. The direction of the laser beam emitted by the laser gun 4 points to the position close to the two ends of the contact seam of the two pressure rollers 9. The guide wheels 6 are respectively arranged with The up and down of the laser beam are parallel to the pressure roller, and the adjacent guide wheels or between the guide wheel and the pressure roller rotate in reverse.

[0031] In addition, a cleaning splint 10 can be arranged in front of the pressure roller 9 to remove impurities or dirt on the surface of the belt. Also guide groove 8 should be set before pressure roller 9, so...

Abstract

The invention discloses a sprinkler tube plate laser bonder. A laser gun is fixed on a support which is connected with a worktable as a whole. The laser gun is adjustable in the positions of front and back, and high and low. Two tube plates penetrate through along a laser tube and are jointed at a compression roller after passing through a guide wheel and a guide slot. The laser gun shoots continuous beams to form a circular spot at the joint position of the tube plates in order to melt the inner surfaces of the two tube plates in an extremely short time, and then the tube plates are compressed and bonded firmly by the compression roller and are finally wound up by a wind-up roller. The sprinkler tube has firm bonding and smooth and attractive surface.

Description

technical field [0001] The invention belongs to the field of hot-melt bonding, and in particular relates to a laser bonder for water-spray tape tape. Background technique: [0002] At present, the sprinkler belts produced at home and abroad mainly include two types. One is to extrude plastic from a plastic extruder, press it into sheets through three rolls, cut it into strips of a certain size with a cutting machine, and then bond or weld the two sides of the same width into a tubular shape , Because there are bonded wings on both sides, it is called a double-wing water spray belt. The other is to directly shape the plastic through the blowpipe process through the plastic extruder, which is referred to as the blowpipe belt for short. [0003] Compared with the two types of water spray belts, the processing technology of the double-wing water spray belt is more complicated, but its edge strength is high. If the bonding is firm, under the condition of water pressure, the bel...
