Double-channel gluing head of back plate folding and gluing machine

Abstract

The invention discloses a double-channel gluing head of a back plate folding and gluing machine. The double-channel gluing head comprises a box body, a U-shaped plate is welded on the upper surface of the box body, and a first air cylinder is fixedly mounted on the upper surface of the U-shaped plate through a bolt. The double-channel gluing head uniformly coats hot-melt PUR glue between two back plates, a part 0.1 mm-1 mm in length is reserved on each of the upper part and the lower part of the outer surface of each of the two base plates, the back plates are taken out after being cooled for 10 seconds-20 seconds, the two back plates can be unfolded by 180 degrees for use due to the fact that the PUR glue has high toughness and the two base plates are bonded together through a gluing layer, four products can be machined by the device on one station, quality is guaranteed, efficiency is doubled, and therefore the manufacturing cost of finished products is reduced; a product which can be finished by two devices in one day originally can be finished by one device in one day now, so that the device investment is reduced, the energy consumption is also reduced, and the device is more environment-friendly and more economical; and the labor force is saved, and the work of two persons in one day originally can be finished by one person in one day now.

Description

technical field [0001] The invention belongs to the technical field of gluing heads, and in particular relates to a double-channel gluing head of a backboard folding gluing machine. Background technique [0002] With the continuous development of the furniture industry, a technology of sticking cabinet backboards with self-adhesive tape has been replaced by PUR hot-melt adhesive technology, because PUR hot-melt adhesive has good toughness and high peel strength. And good heat and humidity resistance and chemical resistance, good adhesion to metals, plastics and wood, etc., and the strength increases rapidly, and has good viscosity, stability and suitable equipment operation in the heating and melting state Therefore, PUR glue is gradually widely used in the furniture industry. PUR glue used in backboard bonding technology has several characteristics: environmental protection, low cost, high bonding strength, more stable and reliable quality, but the production efficiency is...

AI Technical Summary

Problems solved by technology

PUR glue used in backboard bonding technology has several characteristics: environmental protection, low cost, high bonding strength, more stable and reliable quality, but the production efficiency is not high

[0003] At present, this kind of equipment needs to be imported from abroad, the price of the equipment is high, and the purchase cycle is long. Moreover, one station of this equipment only processes two products at a time, and there is no obvious improvement in efficiency.
