[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0020] A convenient hot melt adhesive spraying system, such as Figures 1 to 2As shown, it includes a mobile frame 1, an n-shaped frame 2, a glue spraying workbench 3, a glue storage cylinder 4, a quantitative gear pump 5, a lead screw 6, a drive motor 7, a lead screw nut 8, a glue spraying hose fixing plate 9, a glue spraying hose 10, a glue delivery pipe 11, a rotating rod 12, a sleeve 13, a connecting plate 14, a spring 15, a sealing seat 16, a pull ring 17, a liquid level observation window 18, a filter screen cover 19, an internal filter screen 20, a fixing plate 21, an ear plate 22, and a heat tracing cable 23.

[0021] The mobile frame 1 includes a frame plate, with braked wheels at the bottom and a push-pull handle on one side. The mobile frame 1 allows for the movement of the adhesive spraying system, improving convenience.

[0022] The mobile frame 1 is equipped with an n-shaped frame 2, a glue spraying workbench 3, a glue storage cylinder 4, and a quantitative gear pump 5.

[0023] A liquid level observation window 18 is provided on the side wall of the glue storage cylinder 4 to facilitate observation of the amount of glue liquid inside the glue storage cylinder 4.

[0024] Of course, to prevent the glue inside the glue storage tank 4 from becoming viscous, a stirring system and a heat preservation and heating system can be equipped to improve the quality of the glue spraying.

[0025] A lead screw 6 is mounted on the n-shaped frame 2. The lead screw 6 is connected to a drive motor 7. The bottom of the lead screw nut 8 is connected to a glue spraying tube fixing plate 9. A glue spraying tube 10 is mounted on the glue spraying tube fixing plate 9. A fixing plate 21 is provided on the outer wall of the glue spraying tube 10. Ear plates 22 are provided at both ends of the fixing plate 21. The ear plates 22 are fixed to the glue spraying tube fixing plate 9 by bolts. The rotation of the lead screw 6 can drive the lead screw nut 8 and the glue spraying tube 10 to move in position, which facilitates the glue spraying operation on the items.

[0026] The top of the glue spraying tube 10 is connected to the glue delivery pipe 11, which is connected to the lower part of the glue storage cylinder 4 via a quantitative gear pump 5. The glue spraying workbench 3 is located below the glue spraying tube 10. A rotating rod 12 is rotatably installed at the bottom of the glue spraying tube fixing plate 9. A sleeve 13 is fitted at the lower end of the rotating rod 12, and a connecting plate 14 is fixed at the bottom of the sleeve 13.

[0027] A pull ring 17 is provided at the bottom of the connecting plate 14.

[0028] After the glue spraying operation is completed, the glue outlet can be sealed by the sealing seat 16 to prevent dust and other impurities from adhering to it and affecting the glue removal quality. When glue spraying is required, the connecting plate 14 can be pulled down by the pull ring 17 to make the sealing seat 16 disengage from the bottom of the glue spraying tube 10. Then, the rotating rod 12 can be rotated to a position that does not affect the glue spraying operation. After the operation is completed, the tubes can be reset.

[0029] The inner wall of the glue storage cylinder 4 is equipped with a filter screen 19 at the glue outlet. The filter screen 19 can perform the first stage of filtration on the glue liquid. The filter screen 19 can be cleaned regularly to avoid clogging.

[0030] An internal filter 20 is installed on the upper part of the inner wall of the glue spray tube 10. The bottom of the internal filter 20 has an upward-convex arc-shaped structure. The internal filter 20 can perform a second-stage filtration of the glue, and the arc-shaped structure can reduce the frequency of clogging of the internal filter 20, requiring regular cleaning.

[0031] A heat tracing cable 23 is wrapped around the outer wall of the glue spraying tube 10, and the heat tracing cable 23 is connected to a power supply. The heat tracing cable 23 can be heated during the glue spraying process to prevent the glue from solidifying.

[0032] This utility model is easy to move and use, and can seal the bottom of the glue spray tube 10 to prevent dust from adhering and improve the quality of glue spraying.

[0033] The present invention has been described above with reference to the accompanying drawings.
