The workbench 1 provides a place for coating hot melt adhesive on products.

[0039] An anti-skid pad 20 is provided on the upper part of the workbench 1, and the anti-skid pad 20 is connected to the workbench 1. The high friction surface of the anti-skid pad 20 can prevent the material 22 to be bonded from sliding or moving on the workbench 1, thereby ensuring the stability of the object and avoiding accidental sliding during operation. Several clamping members 17 are provided on the upper part of the workbench 1, and the clamping members 17 are connected to the workbench 1.

A plurality of through openings 7 are provided at the bottom of the glue melt box 4. The through openings 7 are connected to the inside of the glue melt box 4. The positions of the plurality of through openings 7 and the plurality of heating tubes 6 correspond one to one. A glue outlet nozzle 8 is provided at the through opening 7. The glue outlet nozzles 8 are connected to the heating tube 6 and the glue melt box 4. Since the partition plate 5 divides the inside of the glue melting box 4 into several compartments with equal distances, the heating tubes 6 between the partition plates 5 can heat and melt the hot melt glue sticks 23, and the through openings 7 at the bottom of the heating tubes 6 provide a connecting channel for connecting the heating tubes 6 with the glue outlet nozzles 8, so that the several heating tubes 6 can heat the several hot melt glue sticks 23 into liquid hot melt glue at the same time, and then the molten hot melt glue flows through the glue outlet nozzles 8 to the surface of the material 22 on the workbench 1, and the flowing hot melt glue is equidistant and uniform.

[0043] An insulation layer 19 is provided between the heating tube 6 and the melt box 4, and the insulation layer 19 is connected to the heating tube 6 and the melt box 4.

A limiting ring 18 is arranged on the side of the push plate 16 away from the elastic member 15, and the limiting ring 18 is an integral structure with the support plate. The limiting ring 18 can limit the hot melt glue stick 23, so that it is always in a vertical state during the melting process, and prevents it from tipping over in the melt box 4.

[0045] The coating part 202 is provided with a scraper 9, which is connected to the coating part 202. A fan 10 is provided on the scraper 9, which is connected to the coating part 202. An electric heating wire 11 is provided at the air outlet of the fan 10, which is connected to the fan 10.

When the glue nozzle 8 is glued to the surface of the material 22 on the workbench 1, the soft adhesive material 22 is attached to it and covers the top. Then the scraper 9 scrapes the top surface to ensure that the hot melt adhesive can be evenly coated between the two materials 22. The hot air provided by the fan 10 through the electric heating wire 11 can make the coated hot melt adhesive quickly solidify and dry, thereby increasing the firmness of the bonding.

[0046] The workbench 1 is provided with a collecting trough 12, and a collecting box 13 is arranged inside the collecting trough 12.

The collecting box 13 is detachably fixedly connected to the workbench 1, so that the collecting box 13 can be conveniently taken out for cleaning or waste processing.

[0047] The operating steps of the hot melt adhesive coating and laminating machine of the utility model are as follows:

[0049] The material 22 to be bonded is placed on the workbench 1 and fixed to the workbench 1 using the clamp 17. One end of another soft material 22 to be bonded is passed through between the melt adhesive portion 201 and the coating portion 202 of the frame 2, and the starting end of the material 22 is fixed.

[0050] All the heating tubes 6 are started to heat, and the heating tubes 6 heat and melt the hot melt glue sticks 23 partially located in the heating tubes 6. The operating frame 2 is pushed from one end of the workbench 1 away from the collecting tank 12 to the other end. During this period, the melted hot melt glue stick 23 will flow out from the glue nozzle 8 and fall to the surface of the material 22 on the workbench 1. Since the distance between each adjacent glue nozzle 8 is equal, the hot melt glue leaving the glue nozzle 8 and falling on the surface of the material 22 is equidistant and uniform. During this period, the push plate 16 is acted upon by the elastic member 15, and will always provide downward pressure on the hot melt glue stick 23, so that the hot melt glue stick 23 can continuously replenish the heating tube 6.

[0051] The soft material 22 to be bonded passing through the frame 2 is then adhered to the material 22 to be bonded on the workbench 1, and then the scraper 9 scrapes the surface of the soft material 22 to ensure that the hot melt adhesive can be evenly coated between the two materials 22. The hot air provided by the fan 10 through the electric heating wire 11 can make the coated hot melt adhesive quickly solidify and dry, thereby increasing the firmness of the bond.
