Description

Technical Field

[0001] The utility model relates to the technical field of glue coating devices, in particular to a glue coating device for rubber products. Background Art

[0002] In the rubber product industry, it is usually necessary to coat various rubber products to facilitate the subsequent process of attaching accessories. For products such as rubber bushings, the rubber bushings need to be coated on their outer walls. The traditional glue coating method is mostly manual glue coating. By this method, the thickness of the coated glue layer is uneven, and the work efficiency is not high.

[0003] After retrieval, a utility model patent in China proposed a glue coating device for rubber products (Publication No.: CN219273498U), which includes a control cabinet. The upper end of the control cabinet is fixedly connected with an operation panel. One side of the middle part of the upper end of the operation panel is fixedly connected with a vertical plate. One side end face of the vertical plate is provided with a servo motor in the middle of one side. The output end of the servo motor penetrates the vertical plate and is fixedly connected with a glue coating roller. The side end face of the vertical plate far away from the servo motor is provided with a fixed roller. The lower end of one side end face of the vertical plate is fixedly connected with a glue liquid tank, and a valve is arranged at the lower end of one side end face of the glue liquid tank. It drives the glue coating roller to rotate on the upper end of the glue liquid tank through the servo motor, so that the glue coating roller is evenly coated with glue liquid, and during the rotation process, the upper rubber bushing is completed with the glue coating work. However, it still has defects. During the glue coating process, the rubber bushing lacks fixation between the rolling fixed roller and the glue coating roller, which not only easily leads to uneven glue coating, but also the rubber bushing is easy to roll off. Secondly, the glue in the open glue water tank is easily affected by temperature. At low temperature, the glue is easy to become thick, resulting in poor leveling property of the glue, uneven glue coating, and affecting the quality of rubber bushing glue coating.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0023] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , where Figure 1 is a structural schematic diagram of the present utility model; Figure 2 is a structural schematic diagram inside the gluing box of the present utility model; Figure 3 is a structural schematic diagram inside the inverted U-shaped frame of the present utility model; Figure 4 is a structural schematic diagram inside the sliding frame of the present utility model. It includes: storage cabinet 1, gluing mechanism, temperature control mechanism and positioning mechanism.

[0024] In the specific implementation process, such as Figure 1 , Figure 3 and Figure 4 shown, a glue application mechanism is connected to the storage cabinet 1. The glue application mechanism includes a glue application box 4, a first stepping motor 5, and a glue application roller 6. The upper surface of the storage cabinet 1 is fixedly connected with a glue application box 4. A first stepping motor 5 is installed on one side surface of the glue application box 4. The output end of the first stepping motor 5 penetrates the side surface of the glue application box 4 and is fixedly connected with a glue application roller 6 through a coupling. The other end of the glue application roller 6 is rotatably connected to the inner side surface of the glue application box 4. A positioning mechanism is connected to the storage cabinet 1. The positioning mechanism includes an inverted U-shaped frame 11, a cylinder 12, an adjustment block 13, a second stepping motor 16, a rotating shaft 17, a turntable 15, a sliding frame 18, a trapezoidal lead screw 19, a slider 20, and an arc-shaped positioning rod 21. The upper surface of the storage cabinet 1 is fixedly connected with an inverted U-shaped frame 11. A cylinder 12 is installed on the upper surface of the inverted U-shaped frame 11. The output end of the cylinder 12 penetrates the upper surface of the inverted U-shaped frame 11 and is fixedly connected with an adjustment block 13. A second stepping motor 16 is installed on one side surface of the adjustment block 13. The output end of the second stepping motor 16 penetrates the adjustment block 13 and is fixedly connected with a rotating shaft 17 through a coupling. The other end of the rotating shaft 17 is fixedly connected with a turntable 15. A sliding frame 18 is fixedly connected to one side surface of the turntable 15. A trapezoidal lead screw 19 is rotatably connected inside the sliding frame 18. The thread directions at both ends of the trapezoidal lead screw 19 are opposite. The other end of the trapezoidal lead screw 19 penetrates the sliding frame 18. Two symmetrically arranged sliders 20 are threadedly sleeved on the trapezoidal lead screw 19. An arc-shaped positioning rod 21 is fixedly connected to one side surface of the slider 20.

[0025] It should be noted that: when in use, a plurality of rubber bushings are sleeved on the two arc-shaped positioning rods 21 in parallel, and then the trapezoidal lead screw 19 is rotated. The rotation of the trapezoidal lead screw 19 drives the two sliders 20 to move away from each other inside the sliding frame 18. The movement of the sliders 20 drives the movement of the arc-shaped positioning rods 21, so that the two arc-shaped positioning rods 21 move away from each other and abut against the inner side surface of the rubber bushing. The rubber bushing is positioned and fixed by the two arc-shaped positioning rods 21. Then, the cylinder 12 is started. The cylinder 12 drives the downward movement of the adjustment block 13, thereby driving the downward movement of the rubber bushing, so that the rubber bushing abuts against the glue application roller 6. Then, the first stepping motor 5 and the second stepping motor 16 are started. The first stepping motor 5 drives the rotation of the glue application roller 6, so that the glue at the bottom inside the glue application box 4 is smeared on the glue application roller 6. The rotation of the second stepping motor 16 drives the rotation of the turntable 15 through the rotating shaft 17. The rotation of the turntable 15 drives the rotation of the rubber bushing through the arc-shaped positioning rod 21, so that the rubber bushing rolls on the glue application roller 6 for glue application. After the glue application is completed, the cylinder 12 is started again to drive the upward movement of the rubber bushing. Then, the trapezoidal lead screw 19 is reversed, so that the two arc-shaped positioning rods 21 move closer to each other, releasing the positioning and fixing of the rubber bushing. Then, the rubber bushing is removed, and the next glue application process can be carried out.

[0026] Refer to Figure 1 andFigure 2 As shown, a temperature control mechanism is connected inside the glue application box 4. The temperature control mechanism includes an electric heating rod 9, a temperature sensor 7, and a thermostat 8. Two symmetrically arranged electric heating rods 9 are installed on an inner side wall of the glue application box 4. A temperature sensor 7 is installed on one side surface of the glue application box 4, and the probe of the temperature sensor 7 penetrates through the side surface of the glue application box 4. A thermostat 8 is installed on the upper surface of the storage cabinet 1. The electric heating rod 9 and the temperature sensor 7 are both electrically connected to the thermostat 8.

[0027] It should be noted that when the temperature is low, the electric heating rod 9 is started to heat the glue through the electric heating rod 9. During the heating process, the temperature of the glue is detected by the temperature sensor 7, and the temperature sensor 7 transmits the detected temperature signal to the thermostat 8. When the temperature reaches the preset maximum temperature in the thermostat 8, the thermostat 8 controls to turn off the electric heating rod 9. When the temperature drops to the preset maximum temperature in the thermostat 8, the thermostat 8 controls to turn on the electric heating rod 9. Thus, when the temperature is relatively low, the glue in the glue application box 4 can be maintained at an appropriate temperature.

[0028] Reference Figure 1 As shown, support feet 2 are fixedly connected to the four corners of the lower surface of the storage cabinet 1. The support feet 2 play a supporting role to prevent the storage cabinet 1 from directly contacting the ground.

[0029] Reference Figure 1 As shown, a discharge pipe 10 is fixedly communicated with the front end face of the glue application box 4. A matching control valve is installed on the discharge pipe 10. Through the arranged discharge pipe 10, it is convenient to discharge the glue in the glue application box 4 when the machine stops.

[0030] Reference Figure 1 and Figure 3 As shown, two symmetrically arranged sliding rods 14 are fixedly connected to the upper surface of the adjusting block 13. The sliding rods 14 slide through the inverted U-shaped frame 11. Through the arranged sliding rods 14, a limiting effect is achieved, making the up and down movement of the adjusting block 13 more stable.

[0031] Reference Figure 4 As shown, a flower-shaped block 22 is fixedly connected to one end of the trapezoidal lead screw 19 passing through the sliding frame 18. Through the arranged flower-shaped block 22, it is convenient for the trapezoidal lead screw 19 to rotate.

[0032] Anti-slip patterns are provided on the mutually remote side surfaces of the two arc-shaped positioning rods 21. Through the arranged anti-slip patterns, the friction force is increased, making the positioning of the arc-shaped positioning rods 21 to fix the rubber bushing more stable.

[0033] Reference Figure 1 As shown, a through cavity is provided on the front end face of the storage cabinet 1, and two symmetrically arranged cabinet doors 3 are installed in the through cavity. Through the arranged cabinet doors 3, it is convenient for the storage in the storage cabinet 1.

[0034] The working principle provided by the present utility model is as follows: When in use, a plurality of rubber bushings are sleeved on two arc-shaped positioning rods 21 in parallel. Then, the trapezoidal lead screw 19 is rotated. The rotation of the trapezoidal lead screw 19 drives two sliders 20 to move away from each other within the sliding frame 18. The movement of the sliders 20 drives the movement of the arc-shaped positioning rods 21, causing the two arc-shaped positioning rods 21 to move away from each other and abut against the inner side surfaces of the rubber bushings. The rubber bushings are positioned and fixed by the two arc-shaped positioning rods 21. Then, the air cylinder 12 is started, and the air cylinder 12 drives the regulating block 13 to move downward, thereby driving the downward movement of the rubber bushings, causing the rubber bushings to abut against the glue application roller 6. Then, the first stepping motor 5 and the second stepping motor 16 are started. The first stepping motor 5 drives the rotation of the glue application roller 6, so that the glue at the bottom of the glue application tank 4 is applied onto the glue application roller 6. The rotation of the second stepping motor 16 drives the rotation of the turntable 15 through the rotating shaft 17. The rotation of the turntable 15 drives the rotation of the rubber bushings through the arc-shaped positioning rods 21, causing the rubber bushings to roll and apply glue on the glue application roller 6, so that the rubber bushings can be automatically coated with glue without manual coating. Moreover, during the coating process, by positioning and fixing the rubber bushings and then rolling to apply glue, not only the coating is more uniform, but also the stability of the glue application is improved. After the glue application is completed, the air cylinder 12 is started again to drive the upward movement of the rubber bushings. Then, the trapezoidal lead screw 19 is reversed, causing the two arc-shaped positioning rods 21 to approach each other and release the positioning and fixing of the rubber bushings. Then, the rubber bushings are removed, and the next glue application process can be carried out. When the temperature is low, the electric heating rod 9 is started, and the glue is heated by the electric heating rod 9. During the heating process, the temperature of the glue is detected by the temperature sensor 7. The temperature sensor 7 transmits the detected temperature signal to the temperature controller 8. When the temperature reaches the preset maximum temperature within the temperature controller 8, the temperature controller 8 controls to turn off the electric heating rod 9. When the temperature drops to the preset maximum temperature within the temperature controller 8, the temperature controller 8 controls to turn on the electric heating rod 9. Thus, when the temperature is relatively low, the glue in the glue application tank 4 can be maintained at an appropriate temperature, avoiding the glue becoming thick due to low temperature and resulting in poor leveling of the glue, so that the coating of the rubber bushings is more uniform and the quality of the glue application on the rubber bushings is also improved.
