By providing the electric heating wire 31, the gas flowing through the sleeve 2 can be heated, and the heated air contacts the end of the glue gun 108, thereby reducing the problem of the nozzle being blocked due to the solidification of the glue after the glue gun 108 stops spraying, making it impossible to spray.

When the inner wall of the pipe is completely covered with the glue, the first motor 11 and the spraying device 110 are turned off, and the pipe is removed. At this time, a set of internal spraying processes of the pipe is completed. When the second motor 22 is turned on to rotate the fan blades 24, the flow rate of the gas in the sleeve 2 is accelerated. During the spraying process, the wind force helps to push the glue to cover the inner wall of the pipe more evenly, thereby improving the efficiency of spraying the glue. By setting the gauze 3, dust and impurities in the air can be reduced from entering the sleeve 2 to cause the nozzle of the glue gun 108 to be blocked, thereby causing spots and particles on the inner wall of the pipe. In addition, impurities can be reduced from adhering to the inside of the nozzle and gradually accumulating to completely block the nozzle, making the spray The problem that the work cannot be carried out normally is solved by setting the electric heating wire 31, so that the gas flowing through the sleeve 2 can be heated, and the heated air contacts the end of the glue gun 108, thereby reducing the problem that the glue solidifies after the glue gun 108 stops spraying and causes the nozzle to be blocked, and the spraying work cannot be carried out. By setting multiple groups of first iron sheets 4 on the inner wall of the sleeve 2, the gas is drained, so that the glue can be evenly sprayed into the inside of the pipe fitting, reducing the uneven spraying or excessive thickness inside the pipe fitting. The pipe fitting is clamped by sliding the second connecting rod 16. At this time, the middle part of the pipe fitting will be bound by the elastic cloth 51 connected to the adjacent second iron sheets 5, and the nuts 19 on both sides of the rotating connecting frame 14 are rotated. The second fixing plate 17 is fixed to complete the clamping of the pipe fitting, and the glue guns 108 on the upper and lower sides spray the glue on the inner wall of the pipe fitting, and the excess glue will drip from the inner wall onto the first rubber box 6 equipped with the sponge 61, thereby reducing the waste of glue during the working process; by setting the first rubber box 6 and the sponge 61, the remaining glue during the spraying process is collected, and the second rubber box 7 and the activated carbon filter element 71 are rotated by connecting the first motor 11, and the smell of the glue during the spraying process is absorbed to achieve the purpose of reducing environmental pollution.
