Problems solved by technology

This hot melt adhesive coating machine is suitable for the adhesive layer coating of self-adhesive trademarks and various types of tapes. The substrate after coating the self-adhesive needs to be compounded with the composite material immediately without cooling. It is suitable for low-temperature coating of the substrate. Cloth, only one substrate can be coated at a time, and the production efficiency is low
Melt glue box and coating This machine conveys hot melt glue through the rubber conveying pipe, the conveying path is long, heat preservation treatment is required when conveying hot melt glue, the coating machine extrudes from the gap of the template coating head, the glue is difficult to release, and the coating efficiency Low, inconvenient to operate, not suitable for hot melt adhesive coating on edge banding, and complex structure

Embodiment 1

[0049] Such as Figure 1~7 As shown, the edge banding back coated hot melt adhesive device, it includes the unwinding device 1 for releasing the edge banding, coating hot melt adhesive on the back side of the edge banding to obtain the melt glue coating of the glued edge banding Device 2, a cooling device 3 for cooling and solidifying the glued edge banding strip and a winding device 4 for winding the glued edge banding strip after cooling and solidification, the unwinding device 1, the coating device, and the cooling device 3 And winding device 4 is arranged in sequence.

[0050] Such as figure 2 As shown, the unwinding device 1 includes an unwinding stand 12, and an unwinding reel 11 is arranged on the unwinding stand 12, and one unwinding reel 11 unwinds one roll of edge banding to be coated each time. The unwinding device 1 also includes a clutch and an automatic switch. The automatic switch is controlled by the clutch, and then the start or stop of unwinding is control...

Embodiment 2

[0072] Such as Figure 8 , Figure 9 As shown, the difference between this embodiment and Embodiment 1 is that: the unwinding device 1 described in this embodiment is provided with more than two unwinding reels 11, and the rewinding device 4 is provided with a connection with the unwinding reels 11. Equal number of winding reels 41. More than two unwinding reels 11 are arranged on the unwinding rack 12, and each unwinding reel 11 unwinds one roll of the edge banding strip to be coated at a time. More than two reels 41 are arranged on the reel 42, and each reel 41 rewinds a roll of glued edge banding at a time, and the number of reels 41 is equal to the number of unwinding reels 11 .

[0073] The width of the edge banding strip is smaller than the length of the glue-coating roller 231, and the glue-coating roller 231 is coated on the whole edge banding strip. Coating roller 231 can coat more than two edge bands at the same time, and more than two edge bands are arranged sid...

Embodiment 3

[0077] Such as Figure 10 , Figure 11 As shown, the difference between this embodiment and Embodiment 2 is that this embodiment also includes a tension adjustment device 5, and the tension adjustment device 5 is arranged between the unwinding device 1 and the melt glue coating device 2 between. The tension adjustment device 5 is provided with a guide wheel 51. The edge banding strip released from the unwinding reel 11 is guided by the guide wheel 51, flattened and tightened, and then sent to the coating device for coating hot melt adhesive to avoid loose edge banding. The phenomenon of missing coating caused by stretching, so that the hot melt adhesive can be coated evenly and the coating quality is good.

[0078] The quantity of the guide wheels 51 is set according to the quantity of the unwinding reel 11, and one guide wheel 51 is arranged for each roll of edge banding.

[0079]The tension adjusting device 5 is also provided with an exhaust fan, which washes and ...

Abstract

The invention relates to the technical field of production equipment of edge bandings, in particular to an edge banding back-coating hot melt adhesive device, which comprises an unreeling device for giving off edge bandings, a melt adhesive coating device, a cooling device and a rolling device, wherein the back surfaces of the edge bandings are coated with hot melt adhesive through the melt adhesive coating device to made gummed edge bandings, the gummed edge bandings are cooled and solidified by the cooling device, the gummed edge bandings after being cooled and solidified are rolled by the rolling device, and the unreeling device, the melt adhesive coating device, the cooling device and the rolling device are orderly arranged. The edge banding back-coating hot melt adhesive device is an automatic device integrated with unreeling, melt adhesive coating, cooling, solidifying and rolling, is particularly suitable for thin edge bandings, the thickness of the thin edge bandings is between 0.2mm and 0.8mm, and is convenient to process the made gummed edge bandings. The coating speed is between 20m / s and 30m / s, the coating amount is from 130g / square meter to 140g / square meter, more than two edge bandings can be coated for one time, and the production efficiency is high.

Description

technical field [0001] The invention relates to the technical field of edge banding strip production equipment, in particular to a device for coating hot melt adhesive on the back of an edge banding strip. Background technique [0002] Edge banding is a material for protecting, decorating and beautifying the section of furniture panels. Its main function is to seal the section of the panel so as to prevent the panel from being damaged by the environment and unfavorable factors during use. Unique color and texture design and other decorations make the applied furniture panel products more textured and three-dimensional. For flat edge banding products, back coating treatment is an important process related to product quality. [0003] Application number is 95216048.X Chinese utility model patent discloses a kind of hot-melt glue coating machine, comprises a melt glue box, a coating this machine and is connected between the melt glue box and the rubber delivery pipe between th...
