At this time, the glue coating roller 19 also rotates. The second gear 15 and the first gear 14 are engaged with each other and are driven to rotate by the first gear 14. At the same time, the second gear 15 drives the second fixed rod 113 to rotate. At this time, the glue blocking roller 18 starts to rotate. The glue blocking roller 18 brings out the glue inside the glue storage barrel 17 through its special groove structure, and pours the glue on the surface of the glue coating roller 19 during the rotation. At this time, the soles to be coated with glue are placed on the conveyor belt 111. The shoe sole starts to move along the conveyor belt 111. When the shoe sole passes under the glue coating roller 19, the glue on the surface of the glue coating roller 19 will be evenly spread on the shoe sole. In this step, the glue blocking roller 18 is set to seal the glue storage barrel 17 when the operation is stopped. During operation, the glue inside the glue storage barrel 17 can be brought out and dropped on the surface of the glue coating roller 19 through its special groove setting, and the glue coating work is carried out by the contact between the glue coating roller 19 and the shoe sole, which can make the glue coated on the shoe sole more uniform, reduce the steps of repeated mechanical operations, and improve work energy efficiency.

[0027] Further, such as Figure 2 、 Figure 4 and Figure 5 As shown, the inner wall of the back panel 12 is fixedly connected to a pair of parallel second side panels 2; the outer walls of the pair of second side panels 2 are fixedly connected to an electric push rod 23; the inner walls of the pair of second side panels 2 are hinged with an adjustable opening and closing door 21; the outer walls of the pair of adjustable opening and closing doors 21 are slidably connected to the limit rod 22; the terminals of the pair of electric push rods 23 are hinged to the limit rod 22; when working, when the sole is placed on the conveyor belt 111, the sole moves under the drive of the conveyor belt 111, and at this time the electric push rod 23 pushes the limit rod 22 to control the limit rod 22 to slide on the adjustable opening and closing door 21, and the limit rod 2 2, the adjustable opening and closing door 21 starts to rotate through the hinge structure of the second side panel 2, and the opening and closing distance of the adjustable opening and closing door 21 is adjusted so that soles of different sizes can pass through the adjustable opening and closing door 21. This step is provided with the second side panel 2, the adjustable opening and closing door 21, the limit rod 22 and the electric push rod 23, so that the position of the sole placed on the conveyor belt 111 can be adjusted before the sole enters the gluing area, ensuring that the sole is in the middle position of the conveyor belt 111 to better receive the gluing work of the gluing roller 19, thereby reducing the problem of uneven gluing caused by the incorrect position of the sole.

[0028] Further, such as Figure 2 and Figure 4 As shown, a pair of rolling bearings 3 are rotatably connected to the inner walls of the adjustable opening and closing doors 21; the rolling bearings 3 are multiple and evenly distributed on the inner walls of the adjustable opening and closing doors 21; during operation, when the sole passes through the adjustable opening and closing door 21 with the adjusted size, the sole will first contact the rolling bearings 3 on the inner wall of the adjustable opening and closing door 21, and enter the glue coating area under the drive of the rolling bearings 3. This setting can reduce the friction between the sole and the inner wall of the adjustable opening and closing door 21 when the sole passes through the adjustable opening and closing door 21, and the rotation of the rolling bearings 3 facilitates the sole to pass through the adjustable opening and closing door 21, reducing the occurrence of delayed operations such as jamming at the adjustable opening and closing door 21 due to excessive friction of the sole.

[0029] Further, such as Figure 2 and Figure 3 As shown, the side wall of the first gear 14 is fixedly connected to a heating device 4; the middle part of the heating device 4 is connected to a heat-conducting wire 41; the heat-conducting wire 41 is arranged inside the first fixed rod 112; when working, the heating device 4 will continuously heat the heat-conducting wire 41, and at this time the heat-conducting wire 41 transfers heat to the inside of the glue coating roller 19. This step can increase the overall temperature of the glue coating roller 19 by providing the heating device 4 and the heat-conducting wire 41, thereby increasing the temperature of the glue, enhancing the activity of the glue on the surface of the glue coating roller 19, and thereby increasing the adhesion of the glue, ensuring the fluidity of the glue when the glue coating roller 19 is coating the sole, so that the adhesion of the glue applied to the sole can be maintained for a longer time.

[0030] Further, such as Figure 1 、 Figure 2 and Figure 5 As shown, a pair of parallel support rods 5 are fixedly connected to the inner wall of the backboard 12 near the top; a glue feed cylinder 52 is fixedly connected to the top of the support rod 5 near the backboard 12; a plurality of glue outlet cylinders 51 are fixedly connected to the support rod 5 facing the conveyor belt 111; when work stops, there are no more soles that need to be glued on the conveyor belt 111, and all devices stop operating at this time, and a glue remover is injected into the glue feed cylinder 52, and the glue remover flows on the support rod 5 through the glue outlet cylinder 51 and is sprayed on the device. This step is provided with support rods 5, glue outlet cylinders 51 and glue feed cylinders 52. After the work is completed, the glue adhering to devices such as the conveyor belt 111 and the glue coating roller 19 can be cleaned through the glue remover degumming principle, thereby reducing the difficulty of cleaning after the operation and increasing the service life of the device.

[0031] Further, such as Figure 1 、 Figure 2 、 Figure 5 and Figure 6 As shown, the terminals of the multiple glue discharge cylinders 51 are fixedly connected with glue outlets 6; the end of each glue outlet 6 is fixedly connected with an adjusting switch 61; when spraying the degumming agent to the device, the flow rate of the glue outlet 6 at the outlet of the glue discharge cylinder 51 can be controlled by adjusting the switch 61. This step can control the amount of degumming agent required after the work is completed according to the number of plastic shoes on the assembly line, reduce the waste of degumming agent, and further reduce the difficulty of cleaning after the operation.

[0032] Working principle: the motor 13 drives the first gear 14 at the output end to rotate, and the first gear 14 will drive the first fixed rod 112 to rotate. At this time, the glue coating roller 19 also rotates accordingly, and the second gear 15 and the first gear 14 are engaged with each other and are driven to rotate by the first gear 14. At the same time, the second gear 15 will drive the second fixed rod 113 to rotate. At this time, the glue blocking roller 18 starts to rotate. The glue blocking roller 18 will bring out the glue inside the glue storage barrel 17 through its special groove structure, and pour the glue on the surface of the glue coating roller 19 during the rotation. At this time, the soles to be glued are placed on the conveyor belt 111, and the soles start to move along the conveyor belt 111. When the soles pass under the glue coating roller 19, the glue on the surface of the glue coating roller 19 will be evenly spread on the soles. When the soles are placed on the conveyor belt 111, the soles move driven by the conveyor belt 111. At this time, the motor The push rod 23 pushes the limit rod 22 to control the limit rod 22 to slide on the adjustable opening and closing door 21. Driven by the sliding of the limit rod 22, the adjustable opening and closing door 21 starts to rotate through the hinge structure of the second side panel 2. The opening and closing distance of the adjustable opening and closing door 21 is adjusted so that soles of different sizes can pass through the adjustable opening and closing door 21. When the sole passes through the adjustable opening and closing door 21 with the adjusted size, the sole will first contact the rolling bearing 3 on the inner wall of the adjustable opening and closing door 21, and enter the gluing area under the drive of the rolling bearing 3. During operation, the heating device 4 will continuously heat the heat conducting wire 41. At this time, the heat conducting wire 41 transfers heat to the inside of the gluing roller 19. When the work stops, there is no longer any sole that needs to be glued on the conveyor belt 111. At this time, all devices stop operating, and the glue remover is injected into the glue inlet cylinder 52. The glue remover flows on the support rod 5 through the glue outlet cylinder 51 and is sprayed on the device.
