Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1 , Figure 2An embodiment of this utility model provides an automatic feeding, weighing, and mixing device for rubber processing, comprising a mixing tank 1, with fixed plates 13 fixedly connected to both upper parts of the outer wall of the mixing tank 1, a feeding hopper 14 fixedly connected inside the fixed plates 13, a motor 15 fixedly connected to one side of the outer wall of the feeding hopper 14, a rotating shaft 16 fixedly connected to the output end of the motor 15, a weighing plate 17 fixedly connected to the outside of the rotating shaft 16, a stabilizing component fixedly connected to the outside of the rotating shaft 16, the stabilizing component being used to ensure the stability of the weighing plate 17 during rotation, a sensor 21 fixedly connected to the bottom of the weighing plate 17, the weighing plate 17 being rotatably connected to the inside of the feeding hopper 14, a guide pipe 23 fixedly connected to the bottom of the feeding hopper 14, one end of the guide pipe 23 fixedly connected to both upper parts of the inside of the mixing tank 1, a solenoid valve 24 fixedly connected to the outside of the guide pipe 23, and a discharge pipe 9 fixedly connected to one lower part of the outer wall of the mixing tank 1.

[0031] The stabilizing component includes a disc 19, which is fixedly connected to one side of the outer wall of the feed hopper 14. An arc-shaped groove 20 is provided on one side of the inner wall of the disc 19. A rotating rod 18 is fixedly connected to one side of the rotating shaft 16 and is slidably connected inside the arc-shaped groove 20. One side of the rotating shaft 16 is rotatably connected to the inside of the disc 19. A stop block 22 is fixedly connected to one side of the inner wall of the feed hopper 14, and one side of the weighing plate 17 is attached to the upper part of the stop block 22.

[0032] Raw materials are poured into the feed hopper 14 via external equipment and fall onto the weighing plate 17. The weight is sensed by the sensor 21. When the weight on the weighing plate 17 reaches the set weight value, the sensor 21 receives the value and transmits it to the motor 15, causing the motor 15 to start automatically. This drives the rotating shaft 16, which in turn drives the weighing plate 17 and the rotating rod 18 to rotate. The rotating rod 18 slides inside the arc groove 20, ensuring the stability of the weighing plate 17. The rubber raw materials fall into the guide pipe 23. At the same time, the solenoid valve 24 is automatically activated, allowing the rubber raw materials to be fed into the mixing tank 1. This achieves automated quantitative feeding, improving the accuracy and efficiency of feeding. After the weighing plate 17 rotates and pours the rubber raw materials, the motor 15 starts again, causing the rotating shaft 16 to rotate and reset the weighing plate 17. The weighing plate 17 is blocked by the stop block 22 to prevent tilting during reset.

[0033] Reference Figure 1 , Figure 3 , Figure 4A support frame 2 is fixedly connected to the upper part of the mixing tank 1. A drive device 3 is fixedly connected to the upper part of the support frame 2. A rotating shaft 4 is fixedly connected to the output end of the drive device 3. A stirring blade 6 is fixedly connected to the lower side of the outer wall of the rotating shaft 4. Four connecting rods 7 are fixedly connected to the upper and lower sides of the outer side of the rotating shaft 4. A scraper 8 is fixedly connected to one end of the connecting rod 7. The stirring blade 6 and the scraper 8 are rotatably connected inside the mixing tank 1. One side of the scraper 8 is attached to the inner wall of the mixing tank 1. An installation sleeve 5 is rotatably connected to the outer side of one side of the rotating shaft 4. The installation sleeve 5 is fixedly connected to the bottom side of the inner side of the mixing tank 1.

[0034] The mixing tank 1 has an internal cavity 11, and a heating wire 12 is installed inside the cavity 11. A control panel 10 is fixedly connected to one side of the outer wall of the mixing tank 1. The control panel 10 is electrically connected to the drive device 3, motor 15, sensor 21, solenoid valve 24 and heating wire 12, so that it can control the operation of these devices and improve the ease of use of the device.

[0035] When the rubber raw material enters the mixing tank 1, the heating wire 12 is activated to heat and melt the rubber raw material. At the same time, the drive device 3 is driven to rotate the rotating shaft 4 inside the mounting sleeve 5, causing the stirring blade 6 to rotate. Simultaneously, the connecting rod 7 drives the scraper 8 to rotate, thus stirring the rubber raw material and scraping the inner wall of the mixing tank 1. This achieves both heating and melting of the rubber raw material and thorough stirring. The scraping of the inner wall of the mixing tank 1 by the scraper 8 prevents the rubber raw material from adhering to the tank wall, improving the stirring effect and the utilization rate of the raw material.

[0036] Working principle: When the device is needed, raw materials are poured into the feed hopper 14 via external equipment. The raw materials fall onto the weighing plate 17, where the sensor 21 senses the weight. When the weight on the weighing plate 17 reaches the set value, the sensor 21 receives the value and transmits it to the motor 15, causing the motor 15 to start automatically. This motor drives the rotating shaft 16, which in turn rotates the weighing plate 17 and the rotating rod 18. The rotating rod 18 slides inside the arc-shaped groove 20, ensuring the stability of the weighing plate 17. The rubber raw materials then fall into the guide pipe 23. Simultaneously, the solenoid valve 24 automatically activates, feeding the rubber raw materials into the mixing tank 1, thus achieving automation. Quantitative feeding improves the accuracy and efficiency of feeding. When the rubber raw material enters the mixing tank 1, the heating wire 12 is activated to heat and melt the rubber raw material. At the same time, the drive device 3 is driven to rotate the rotating shaft 4 inside the mounting sleeve 5, causing the stirring blade 6 to rotate. Simultaneously, the connecting rod 7 drives the scraper 8 to rotate, which stirs the rubber raw material and scrapes the inner wall of the mixing tank 1. This achieves heating, melting, and thorough stirring of the rubber raw material. The scraping of the inner wall of the mixing tank 1 by the scraper 8 prevents the rubber raw material from adhering to the tank wall, improving the stirring effect and the utilization rate of the raw material.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
