[0030] In the embodiment, a bottom plate 202 is fixedly connected with the outer wall of the right side plate 20 through bolts, and the motor 28 is fixedly connected with the top of the bottom plate 202 through bolts. The bottom plate 202 supports and fixes the motor 28, thereby ensuring the installation stability of the motor 28.

[0031] In the embodiment, mounting blocks 200 are fixedly arranged at the top and bottom of the side plate 20, mounting holes 201 are formed in the top of the mounting blocks 200, and connecting bolts for connecting the base 1 are arranged in the mounting holes 201. The design facilitates the stable and firm installation of the side plate 20 on the top of the base 1 through bolts.

[0032] In the embodiment, the roller body 27 and the connecting shaft 270 are fixedly connected through bolts, and the roller body 27 and the connecting shaft 270 are both made of alloy aluminum. The bolt fixing mode ensures the firm connection between the roller body 27 and the connecting shaft 270, and the alloy aluminum has the advantages of light weight and corrosion resistance, thereby ensuring the service life of the roller body 27 and the connecting shaft 270.

[0037] It should be noted that the outer wall of the shell 23 in the embodiment is provided with two strip-shaped grooves 230, and the arrangement of the strip-shaped grooves 230 facilitates the user to observe the positions of the limiting rod 24 and the connecting rod 25, thereby facilitating the user to smoothly disassemble and assemble the connecting shaft 270 and the roller body 27.

[0038] It should be noted that the motor 28 involved in the embodiment is a conventional technology, and will not be described here.

[0039] In specific use, the user first connects the power supply of the motor 28, and the motor 28 starts to work. The output shaft of the motor 28 rotates to drive the first gear 280 to rotate. Since the first gear 280 is engaged with the second gear 29, the second gear 29 rotates to drive the rotating disc 21 to rotate, and the rotating disc 21 drives the shell 23, the limiting rod 24 and the connecting shaft 270 to rotate. The connecting shaft 270 simultaneously drives the roller body 27 to rotate, and the winding and unwinding of the hot melt adhesive coating base material can be realized with the rotation of the roller body 27.

[0040] When the roller body 27 needs to be disassembled, the user first pulls the pull ring 250 to the two sides, the pull ring 250 drives the connecting rod 25, the limiting disc 240 and the limiting rod 24 to move horizontally, and the spring 26 is compressed by the limiting disc 240, when the limiting rod 24 is separated from the limiting groove 2700, the user lifts the roller body 27 upward, the roller body 27 drives the connecting shaft 270 to be separated from the groove 220, and the roller body 27 is disassembled.
