[0024] In the embodiment, the moving assembly includes a guide column 16 fixedly installed on the outer surface of the sliding block 15, the inner wall of the drying box 1 near the C-shaped plate 13 is obliquely provided with a guide groove 17 matched with the guide column 16, and the guide column 16 and the inner wall of the guide groove 17 are slidingly installed, and the guide groove 17 is oppositely arranged to the inclination direction of the first electric heating plate 3.

[0025] When the first electric heating plate 3 and the second electric heating plate 4 are inclined outward, the guide posts 16 installed on the two sides of the second electric heating plate 4 will slide in the guide grooves 17 inclinedly formed on the inner wall of the drying box 1, so that the guide posts 16 can drive the second electric heating plate 4 to move to the direction of the feeding port of the drying box 1 under the guidance of the guide grooves 17, and the heating distance between the second electric heating plate 4 and the first electric heating plate 3 is increased, so as to increase the drying time of the glue solution and ensure the drying effect of the glue solution.

[0026] In the embodiment, the outer surface of the glue outlet pipe 7 is slidably provided with an adjusting plate 18 for controlling the glue outlet amount, the outer surface of the adjusting plate 18 is penetrated by a locking bolt 19, the end of the locking bolt 19 abuts against the outer surface of the glue outlet pipe 7, and the outer surface of one side of the glue outlet pipe 7 is provided with a speed regulating knob 20 capable of controlling the rotating speed of the stepping motor 21.

Moreover, the present application mainly protects the mechanical device, so the control mode and the circuit connection will not be explained in detail. The side edge of the adjusting plate 18 abuts against the outer periphery of the speed regulating knob 20, and the speed regulating knob 20 is made of rubber, so as to increase the friction between the speed regulating knob 20 and the side edge of the adjusting plate 18.

[0027] When the glue outlet amount of the glue outlet pipe 7 needs to be adjusted, the locking bolt 19 is screwed, and the adjusting plate 18 is moved up and down at this time, so that the adjusting plate 18 adjusts the size of the gap between the glue outlet pipe 7 and the glue applying roller 8, and the adjustment of the glue outlet amount is completed.

When the adjusting plate 18 moves up and down, the speed regulating knob 20 abutting against the side edge of the adjusting plate 18 will also rotate, so that when the glue outlet amount is about to be increased, the speed regulating knob 20 will control the stepping motor 21 to rotate slowly, so as to prolong the drying time of the glue solution when the glue solution is thickened during application, and ensure the drying quality of the glue solution.

[0028] From the above description, it can be seen that the above-mentioned embodiments of the present application achieve the following technical effects: in use, the rubber belt to be coated with glue is inserted into the drying box 1 from between the supporting roller 22 and the glue applying roller 8, and is connected to the winding roller 2 from the discharge port of the drying box 1, and the rubber belt is wound by the stepping motor 21. In the moving process of the rubber belt, the glue solution in the glue storage box 6 is applied to the glue applying roller 8 from the glue outlet pipe 7, and then the glue applying roller 8 applies the glue solution to the surface of the rubber belt, completing the glue coating work on the surface of the rubber belt. The rolling glue coating of the glue applying roller 8 can ensure that the glue solution is uniformly and firmly applied to the surface of the rubber belt, improving the glue coating quality. When the finished adhesive tape passes through the second electric heating plate 4 and the first electric heating plate 3, the heat generated by the second electric heating plate 4 and the first electric heating plate 3 can dry the adhesive on the surface of the adhesive tape, so as to remove the solvent and moisture in the adhesive, and ensure the quality of the adhesive layer; Since the second electric heating plate 4 and the first electric heating plate 3 are arranged obliquely, the temperature from the inlet end to the outlet end of the drying box 1 can gradually increase, the adhesive can be gradually heated and dried, the internal solvent of the adhesive can be prevented from being too fast to dry and remaining, the bubbles can be prevented from being formed, the drying effect of the adhesive can be ensured, and the adhesion performance of the subsequent adhesive can be ensured. When the second electric heating plate 4 dries the adhesive, the heat generated by the second electric heating plate 4 can heat the mercury in the U-shaped tube 9, when the temperature in the drying box 1 is too high, the mercury is heated and expanded, the movable rod 10 and the supporting rod 11 are pushed outwards through the sealing plug 12, the supporting rod 11 applies a pushing force to the C-shaped plate 13, the oblique angle of the first electric heating plate 3 and the second electric heating plate 4 is increased, the distance between the first electric heating plate 3, the second electric heating plate 4 and the adhesive tape is changed, the temperature of the adhesive tape is prevented from being too high to cause the adhesive to be dried too much and affect the adhesion performance of the adhesive. When the first electric heating plate 3 and the second electric heating plate 4 are inclined outwards, the guide columns 16 installed on the two sides of the second electric heating plate 4 can slide in the guide grooves 17 obliquely arranged on the inner wall of the drying box 1, the guide columns 16 can drive the second electric heating plate 4 to move towards the inlet end of the drying box 1 under the guidance of the guide grooves 17, the heating distance between the second electric heating plate 4 and the first electric heating plate 3 is increased, the drying time of the adhesive is increased, and the drying effect of the adhesive is ensured. When it is necessary to adjust the glue output of the glue outlet pipe 7, the locking bolt 19 is screwed, at this time, the adjusting plate 18 can be moved up and down, the size of the gap between the glue outlet pipe 7 and the glue applying roller 8 is adjusted by the adjusting plate 18, and the glue output is adjusted; after the adjustment is completed, the locking bolt 19 is tightened again, the position of the adjusting plate 18 is fixed, and the stability of the adjusting plate 18 during use is ensured. When the adjusting plate 18 moves up and down, the speed knob 20 abutting against the side edge of the adjusting plate 18 rotates at the same time, when the glue output is about to be increased, the speed knob 20 controls the stepping motor 21 to rotate slowly, the drying time of the adhesive is prolonged when the adhesive is thickened, and the drying quality of the adhesive is ensured.

[0029] In addition, it should be understood that, although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, the description manner of the specification is only for the sake of clarity, and the specification should be regarded as a whole, and the technical solutions in each embodiment can be combined appropriately to form other embodiments that can be understood by those skilled in the art.
