[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0029] like Figure 1-Figure 3 As shown, in one embodiment, a glue dripping device for a coating machine includes: a fixed base 1, on which a coating unit 2 and a glue dripping device 3 are detachably mounted. The coating unit 2 is used to coat glue on the upper surface of the film, and the glue dripping device 3 is used to evenly drip glue for coating operations, which improves the use efficiency and coating quality of the coating equipment, reduces glue overflow and reduces production costs, and further optimizes the coating process.

[0030] like Figure 1-Figure 3 As shown, in this embodiment, the coating unit 2 is composed of a rubber pressure roller 21 and a mold 22, which evenly coat the glue dripped from the glue dropper onto the surface of the film by squeezing each other, thereby ensuring the coating quality and uniformity.

[0031] Furthermore, a glue receiving groove is designed below the rubber pressure roller 21 and the mold 22 to recover the glue dripping between the rubber pressure roller 21 and the mold 22 during coating, thereby realizing the recycling and reuse of the glue.

[0032] like Figure 1-Figure 3 As shown, in this embodiment, the glue dripping device 3 is composed of a moving component 31 and an anti-glue overflow component 32. The moving component 31 is responsible for adjusting the position of the glue dripping head to perform the glue dripping operation, while the anti-glue overflow component 32 prevents the glue from overflowing.

[0033] Among them, the moving component 31 includes a cross bar 311 and a slide rail 312. The cross bar 311 cooperates with the slide rail 312 to enable the glue dispensing head to move back and forth within a set wide range to dispense glue, thereby achieving uniform coating on the surface of the film and ensuring the stability and reliability of the coating quality.

[0034] Specifically, the slide rail 312 is detachably installed above the cross bar 311, and a slide table 313 is installed above the slide rail 312. The slide table 313 cooperates with the slide rail 312 to move the glue drop head back and forth; the upper part of the slide table 313 is connected to a fixed bracket 314, and one end of the fixed bracket 314 is provided with a fixed part 3141. The glue drop head is installed above one side of the slide rail 312 through the fixed part 3141, and glue is dripped between the rubber pressure roller 21 and the mold 22 below through the electromagnetic valve and the glue pipeline to perform the operation of coating the upper surface of the product.

[0035] In addition, the moving assembly 31 further includes a crossbeam frame 315 , which spans the entire width of the coating unit 2 and is used to install the crossbar 311 and the rubber baffle 321 and adjust the range of movement.

[0036] Furthermore, the anti-overflow glue assembly 32 includes a glue baffle 321, which is composed of a first baffle 3211 and a second baffle 3212, and is used to prevent glue from overflowing from both sides of the rubber roller 21 and the mold 22 during the coating process. The first baffle 3211 is fixed to one side of the upper part of the crossbeam frame 315, and the second baffle 3212 is detachably installed above the rubber roller 21 and the mold 22 through the first baffle 3211.

[0037] Specifically, the lower part of the second baffle plate 3212 is Y-shaped, which fits the rubber pressure roller 21 and the mold 22. The second baffle plate 3212 is used to control the width of the glue coating to prevent the glue from overflowing from both sides of the rubber pressure roller 21 and the mold 22; a blowing nozzle is also installed on the outer side and bottom of the second baffle plate 3212, and air is blown to the inside of the second baffle plate 3212 through an air compressor and a blowing pipeline to further prevent glue overflow.

[0038] Working principle: The pneumatic system drives the glue dropper to achieve reciprocating motion, and the rubber pressure roller 21 and the mold 22 squeeze each other to evenly coat the glue released by the glue dropper on the film surface. In this process: the UV curing lamp located directly above the mold 22 irradiates and cures the applied glue to ensure that the glue on the film surface can be cured quickly; the glue baffle 321 controls the width of the glue coating to prevent the glue from overflowing to both sides, and the blowing nozzle further prevents the glue from overflowing by blowing air into the inside of the glue baffle 321, keeping the coating process neat and efficient; the glue connection slot directly below the rubber pressure roller 21 and the mold 22 recycles the glue dripping during coating for recycling.

[0039] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
