[0020] Furthermore, in this embodiment, an inverted V-shaped diverter plate 12 is fixed at the bottom of the feed hopper 11. Two discharge ports 26 are opened at the bottom of the feed hopper 11.

Several support columns 111 for supporting the feed hopper 11 are installed between the bottom of the feed hopper 11 and the feeding mechanism support frame 15.

[0021] In this embodiment, the bottom sides of the quantitative bin 131 are screwed to support frames 134. The support frames 134 have a concave design. The two sides of the baffle plate 132 are slidably connected to the concave part of the support frame 134.

The rear end of the electric push rod a133 is screwed to the feeding mechanism support frame 15. The telescopic end of the electric push rod a133 is screwed to the baffle plate 132. The support frame 134 supports the baffle plate 132 to improve the stability of the baffle plate 132. If necessary, the baffle plate 132 is made of high-strength metal.

The two electric push rods b144 are respectively set on the left and right sides of the two opening and closing plates 142. The limiting baffle 145 is located on the outside of the opening and closing plates 142. The two opening and closing plates 142 are opened and closed simultaneously by the two electric push rods b144, so that the rubber scrap particles entering from the metering bins 131 are fed into the mixing bucket 21, thereby realizing the feeding operation of the feeding hopper 141.

[0024] In this embodiment, a connecting shaft 143 is provided between the upper end of the opening and closing plate 142 and the feeding hopper 141. The connecting shaft 143 is fixed on both sides of the bottom end of the feeding hopper 141 and is rotatably connected to the opening and closing plate 142.

[0025] In this embodiment, the control terminal 3 is screwed to the side of the feeding mechanism support frame 15.

[0027] In this embodiment, the rubber scrap particle mixing mechanism 2 includes a mixing tank 21, a stirring motor 22, a rotating shaft 23, and a spiral blade 24. The stirring motor 22 is placed on one side of the mixing tank 21. The rotating shaft 23 is connected to the output end of the stirring motor 22 and is located inside the mixing tank 21. The spiral blade 24 is located on the outside of the rotating shaft 23. The stirring motor 22 controls the rotation of the rotating shaft 23 inside the mixing tank 21, and the rotating shaft 23 drives the spiral blade 24 to rotate, thereby mixing the rubber scrap particles in the mixing tank 21.

[0028] In this embodiment, a connecting rod 25 is fixed between the rotating shaft 23 and the spiral blade 24. The spiral blade 24 is spirally arranged on the outside of the rotating shaft 23, and both ends of the spiral blade 24 are located near the inner end face of the mixing barrel 21. The connecting rod 25 stabilizes the spiral blade 24. The spiral blade 24 extends to the inner wall of the mixing barrel 21, improving the comprehensiveness of the mixing and reducing the dead corners of the mixing.

[0029] In addition, both the mixing tank 21 and the stirring motor 22 are equipped with a mixing mechanism support frame 29 at the bottom. The upper surface of the mixing mechanism support frame 29 is provided with a support 210 for supporting the rotating shaft 23. The upper end of the mixing tank 21 is provided with an inlet 27 corresponding to the outlet 26 of the feeding hopper 141. The bottom of the mixing tank 21 is provided with an outlet 26 for outputting the mixed rubber edge particles. The side of the mixing tank 21 is provided with an observation window 28 opened by a movable hinge to observe the mixing situation.

[0030] Specifically, before use, the user enters the setting interface through the display 33 of the control terminal 3, inputs the required amount of rubber scrap granules according to production needs, sets the preset threshold of the pressure sensor 31, pours the rubber scrap granules into the feed hopper 11, and the granules are diverted through the V-shaped diverter 12 and enter the two quantitative bins 131. The pressure sensor 31 monitors the weight of the granules in the quantitative bins 131 in real time, and the data is transmitted to the control terminal 3 via wireless communication. The support column 111 at the bottom of the feed hopper 11 ensures the stability of the feed hopper 11 and prevents deformation or damage due to excessive granule weight. When the weight of the particles in the metering bin 131 reaches the preset threshold, the pressure sensor 31 sends a signal to the controller 32 via wireless communication (when the real-time data is close to the preset threshold, the feeding speed is slowed down to reduce the error caused by data delay). The controller 32 starts the electric push rod a133, pushes the baffle plate 132 to move backward, opens the discharge port 26 of the metering bin 131, and the rubber edge particles fall from the metering bin 131 into the feeding hopper 141. After receiving the feeding completion signal from the quantitative bin 131 (when the pressure sensor 31 monitors a value of 0), the electric push rod a133 resets, and the baffle plate 132 closes the discharge port 26 under the push of the electric push rod a133, completing one quantitative feeding. Then, the feeding assembly 14 is started, and the controller 32 controls the electric push rod b144 to push the two opening and closing plates 142 to move outward at the same time, opening the discharge port 26 of the feeding hopper 141, and the rubber edge particles enter the mixing tank 21. After feeding is completed, the electric push rod b144 resets, and the opening and closing plate 142 closes the discharge port 26 under the pull of the electric push rod b144. In addition, a pressure sensor 31 is also embedded on the surface of the opening and closing plate 142 to monitor whether the rubber corner particles in the feeding hopper 141 have been fed. When the opening and closing plate 142 is closed, the value monitored by the pressure sensor 31 is 0, indicating that feeding is complete. The installation position of the pressure sensor 31 should avoid contact between the two opening and closing plates 142 when they are closed to avoid monitoring conflicts. The pressure sensor 31 feeds back the monitoring results to the control terminal 3 in real time. The control terminal 3 determines whether the feeding is complete based on this signal. After receiving the feeding completion signal, the controller 32 starts the stirring motor 22. The stirring motor 22 drives the rotating shaft 23 to rotate through the output end. The rotating shaft 23 drives the spiral blade 24 to rotate. The spiral blade 24 pushes the rubber edge particles to the inner wall of the mixing tank 21 to achieve uniform mixing. The mixing time can be set according to the actual production needs and can be adjusted in the control terminal 3. The mixing situation can be observed through the observation window 28 on the side of the mixing tank 21. If uneven mixing or abnormality is found, the mixing time or speed can be adjusted. After mixing, the mixed rubber scraps are discharged from the outlet 26 and enter the next process or storage equipment. After discharge, the equipment is turned off, and the residual particles in the feed hopper 11, metering bin 131, feeding hopper 141 and mixing tank 21 are cleaned to prepare for the next feeding and mixing.

[0031] In the above process, all components work together to ensure accurate feeding and uniform mixing of rubber scrap particles to meet production requirements. The control method is automatic control through controller 32. The control circuit of controller 32 can be implemented by simple programming by those skilled in the art and is common knowledge in the field. This application will not explain the control method and circuit connection in detail.
