Description

Technical Field

[0001] The utility model relates to the technical field of bonding machines, in particular to a right-angle hot-melt bonding machine. Background Art

[0002] EPE (expandable polyethylene) is composed of low-density polyethylene ester through physical foaming to produce countless independent bubbles. It is currently the world's most advanced protective inner packaging material. During the processing of its pearl cotton, it is sometimes necessary to connect two pearl cottons at right angles. Current pearl cotton bonding processing equipment mostly uses a heated iron plate to heat the pearl cotton and then bond them. This bonding method requires two workers to work together and has low bonding efficiency. Utility Model Content

[0003] The utility model aims to provide a right-angle hot-melt bonding machine, which can automatically complete the right-angle bonding work by blowing hot air from a hot-melt plate to melt the bonding part and pulling it through a conveyor belt, thereby effectively improving the bonding efficiency.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions:

[0005] A right-angle hot-melt bonding machine includes a frame;

The upper conveyor belt can drive the vertical material to be transported from right to left, and the lower conveyor belt can drive the flat material to move in the same direction and speed. The melted parts of the flat material and the vertical material are combined and bonded to each other, thereby bonding the two products into right-angle strips.

[0012] The utility model is further configured as follows: the heights of the plurality of vertical material feeding rods are increased in sequence from left to right and the upper side walls of the plurality of vertical material feeding rods are on the same slope;

[0013] Multiple vertical feed rods extend through the rear end of the rear limit plate and are fixed to an adjustment block. The adjustment block is inserted into the rear limit plate and secured with screws. Loosening the screws allows the adjustment block to move up and down on the rear limit plate. During vertical feed, the rear end of the vertical material rests against the rear limit plate, thereby accurately positioning the rear limit plate and improving the positioning accuracy of the bonded product.

[0014] The tilted arrangement of multiple vertical material feeding rods can enable the vertical material to be fed with the left side lower and the right side higher, so that it can be attached to the flat material below after hot melting.

[0017] The electric heating device heats the air and blows the hot air into the air inlet channel through the blower. The hot air then enters the cavity and is discharged from the air outlet. The hot air discharged from the upper air outlet can be used to heat-melt the bottom of the vertical material, and the hot air discharged from the lower air outlet can be used to heat-melt the corresponding parts of the flat material.

[0018] The utility model is further configured as follows: a front limit plate is provided above the hot melt plate, a waist-shaped hole is formed on the right end fold of the front limit plate, and two screws are sleeved in the waist-shaped hole;

[0019] The right side wall of the support rod is formed with a concave plane, and a plurality of evenly distributed threaded holes are formed on the concave plane; screws are screwed into the corresponding threaded holes.

[0020] Loosening the screw waist-shaped holes can make small adjustments on the two screws, thereby achieving small adjustments to the front limit plate; unscrewing the screws can make large adjustments to the front limit plate.
