By the gluing device of the scheme, glue solution flows downwards in the gluing device, sequentially passes through the first flow channel 11, the second flow channel 21 and the third flow channel 31, and then flows out from the lower end of the needle nozzle 3 to the joint surface; when the glue is not needed to be coated, the glue solution in the glue coating device can flow downwards under the action of gravity, overflow solidification is carried out at an outlet at the lower end of the needle nozzle 3, further the third flow channel 31 is blocked or the glue outlet flow is reduced, at the moment, the needle nozzle 3 only needs to be rotated, the second clamping part 32 is staggered with the first clamping part 23, the needle nozzle 3 is moved downwards to be separated from the adapter piece 2, then the other replaced needle nozzle 3 is installed on the adapter piece 2 and is rotated to the first clamping part 23 to be clamped with the second clamping part 32, the needle nozzle 3 is replaced quickly, the whole glue coating device does not need to be disassembled and assembled, and the glue coating device is convenient to maintain.

It will be appreciated that the step of mounting the replacement needle tip 3 to the adaptor 2 may be reversed from the step of dismounting, i.e. mounting the needle tip 3 by moving the needle tip 3 upwards into engagement with the adaptor 2 and then rotating the needle tip 3 to bring the first engagement portion 23 into engagement with the second engagement portion 32.

In addition, most gluing rifle head among the correlation technique adopts monomer extension customization structure, and the processing degree of difficulty is big, and is with high costs to sealed glue is difficult for wasing after solidifying in the pipeline, adopts above-mentioned split type rubber coating device can reduce the processing cost, only need clean needle mouth 3 during the washing, and other positions can not take place the glue solution because the mouth of gluing is far away relatively and solidify usually.

Referring to fig. 2, in some embodiments, the adaptor 2 includes a body 24, an outer ring 25 and an inner ring 26 located inside the outer ring 25 are disposed at a lower end of the body 24, the second flow channel 21 penetrates through the inner ring 26, the body 24, the inner ring 26 and the outer ring 25 together define a mounting position 22, and the first engaging portion 23 is located in the mounting position 22.

Specifically, when the needle nozzle is installed, the upper end of the needle nozzle 3 is located in the installation position 22, and the second clamping portion 32 is clamped with the first clamping portion 23, so that the second flow channel 21 is separated from the installation position 22 through the inner ring 26, the glue solution transmission space and the connection space between the needle nozzle 3 and the adaptor 2 are not affected, and the structure is simple.

The first engaging portion 23 is a locking block located on the inner wall surface of the outer ring 25, and the second engaging portion 32 is located at the upper end of the locking block when engaged with the locking block. The second catching portion 32 is defined in an area between an upper surface of the latch, which blocks the downward movement of the needle tip 3, and a lower surface of the body 24. When the needle nozzle 3 is rotated to make the second clamping part 32 and the clamping block staggered in the longitudinal direction, the clamping block can not limit the downward movement of the needle nozzle 3 any more, and the upper end of the needle nozzle 3 can move out of the mounting position 22 downwards and be separated from the adaptor 2.

Fig. 3 is a plan view of the needle nozzle 3 according to the embodiment of the present application. Referring to fig. 3, in some embodiments, the second engaging portion 32 is a flange extending along the edge of the upper end of the needle tip 3, and the flange is circular arc-shaped, and when the second engaging portion is engaged, the lower end of the flange abuts against the upper end of the first engaging portion.

The clamping blocks and the flanges are multiple, the clamping blocks and the flanges are arranged in a one-to-one correspondence mode, and an avoidance position 33 for avoiding the clamping blocks is arranged between every two adjacent flanges.
