When it is necessary to add ingredients for preparing the automotive rubber sealing ring into the feeding box 4, the second sealing plate 401 is adjusted by the second adjusting part to slide to one side of the feeding box 4, so that the top opening end of the feeding box 4 is in an open state, and then the automotive rubber sealing ring ingredients can be added to the feeding box 4 (see Figure 6 ), when the addition is completed, the second regulating part regulates the second sealing plate 401 to reset. When the ingredients in the feeding box 4 need to be discharged, the first regulating part regulates the first sealing plate 412 to slide to one side of the feeding box 4 so that the bottom opening of the feeding box 4 is in an open state. Then, the ingredients in the feeding box 4 can be discharged under the action of gravity (see Figure 5 ).

[0024] See also Figure 1-Figure 3A storage box 3 is also provided on one side of the mixing box 2, and a blanking box 301 is provided at the bottom of the storage box 3. In this embodiment, the automotive rubber sealing ring ingredients to be mixed are added to the storage box 3 for storage at one time, and the ingredients in the storage box 3 can be discharged from the blanking box 301 under the action of gravity, so as to achieve the effect of automatic feeding. When the amount of ingredients in the storage box 3 is insufficient, the ingredients can be replenished into the storage box 3 through the conveyor belt.

[0025] The feed box 4 is connected to the driving module, which is used to drive the feed box 4 to slide back and forth between the storage box 3 and the mixing box 2; For details, please refer to Figure 6-Figure 7 When the driving module drives the feeding box 4 to move toward the material storage box 3, the top open end of the feeding box 4 slides and fits with the bottom open end of the blanking box 301. When the second adjusting part adjusts the top open end of the feeding box 4 to be in the open state, the ingredients in the storage box 3 can be discharged into the feeding box 4 through the blanking box 301 under the action of gravity. When one blanking is completed, the driving module drives the feeding box 4 to move toward the mixing box 2. At this time, the second adjusting part adjusts the top open end of the feeding box 4 to be closed. During the movement, the bottom open end of the feeding box 4 slides and fits with the top open end of the feeding box 202. The first adjusting part adjusts the bottom opening of the feeding box 4 to be in the open state. The ingredients in the feeding box 4 can fall into the feeding box 202 under the action of gravity. During the blanking process, the second sealing plate 401 is driven by the lifting part to descend to the bottom open end of the feeding box 4 to achieve a sealing effect. , to prevent the waste gas generated during mixing in the mixing box 2 from entering the feed box 4. After the feeding is completed, the driving module drives the feed box 4 to move toward the storage box 3 again. During the movement, the first adjusting part adjusts the first sealing plate 412 to gradually reset and seal the bottom opening of the feed box 4. After it is completely sealed, the lifting part drives the second sealing plate 401 to rise to the top opening end of the feed box 4 again, and repeats the above steps to perform the next feeding operation. In the entire feeding and feeding process, this embodiment can effectively isolate the feed box 4 from the mixing box 2 to prevent the waste gas in the mixing box 2 from being discharged into the feed box 4. At the same time, this embodiment can achieve the effect of equal feeding by setting the feed box 4 for feeding, so as to avoid the continuous feeding of the ingredients in the storage box 3 into the feeding box 202, causing the mixing box 2 to be blocked, thereby improving the stability and efficiency of the mixing box 2 when mixing the ingredients.

[0026] Example 2 Based on Example 1, please refer to Figure 4When the feed box 4 is driven to move toward the storage box 3, in order to prevent the exhaust gas generated by the mixing box 2 from being discharged through the feeding box 202, in this embodiment, a third sealing plate 601 is fixedly arranged on the bottom of the side of the feed box 4 away from the storage box 3, and the lower surface of the third sealing plate 601 is flush with the bottom open end of the feed box 4; it can be explained that when the feed box 4 moves toward the storage box 3, the third sealing plate 601 slides and fits with the top open end of the feeding box 202, thereby achieving the effect of sealing the feeding box 202 to avoid exhaust gas leakage.

[0027] In order to discharge the waste gas generated in the mixing box 2, as a further solution of this embodiment, an exhaust box 5 is fixedly arranged at one end of the third sealing plate 601 away from the feed box 4, and an opening is provided at the bottom of the exhaust box 5, wherein the top of the exhaust box 5 is provided with an exhaust fan 501 connected to the inside of the exhaust box 5, and the other end of the exhaust fan 501 is connected to the exhaust pipe 502; it can be explained that as the feed box 4 moves toward the material storage box 3, the exhaust box 5 can be synchronously driven by the third sealing plate 601 to move toward the feeding box 202, and when the feed box 4 moves to just below the material storage box 3, the exhaust box 5 also moves just above the feeding box 202. At this time, the exhaust fan 501 can be started, and the exhaust fan 501 extracts the waste gas generated in the mixing box 2 through the exhaust box 5 and the exhaust pipe 502 through the exhaust pipe 502 and proceeds to the next step of processing.

[0028] See also Figure 1-Figure 2 In order to close the bottom open end of the blanking box 301, in this embodiment, a fourth sealing plate 503 is slidingly arranged at the bottom open end of the air extraction box 5, and the fourth sealing plate 503 is connected to a third adjusting portion arranged on one side of the air extraction box 5, and the third adjusting portion is used to adjust the fourth sealing plate 503 to slide at the bottom open end of the air extraction box 5; it can be explained that as the air extraction box 5 gradually moves to above the feeding box 202, the fourth sealing plate 503 can be synchronously adjusted to slide at the bottom open end of the air extraction box 5 by the third adjusting portion, so that the position where the bottom open end of the air extraction box 5 is not connected to the feeding box 202 is still sealed by the fourth sealing plate 503, and when the air extraction box 5 moves to directly above the feeding box 202, the third adjusting portion adjusts the fourth sealing plate 503 to slide completely to the side of the air extraction box 5.

[0029] See also Figure 1 and Figure 4The driving module includes a driving box body 6 arranged on one side of the mixing box 2. The driving box body 6 is fixed to the bottom support of the mixing tube 1 through a mounting bracket. A screw is arranged to rotate in the driving box body 6. The screw is fixed to the output end of the driving motor fixedly arranged on the outside of the driving box body 6. A nut is spirally sleeved on the screw, and the nut is fixed to the third sealing plate 601. It can be explained that when the feed box 4 is driven to move, the screw is driven to rotate by the driving motor, and the feed box 4 can be synchronously driven to move through the third sealing plate 601 during the movement of the nut on the screw.

[0030] In addition, the driving module in this embodiment can also be replaced by a synchronous belt transmission mechanism, which is not limited to this, as long as it can actually drive the third sealing plate 601 to move back and forth linearly.

[0031] See also Figure 4 The first adjusting portion includes a first guide rod 414 fixedly arranged on the outer side wall of the feeding box 4, and a first guide seat 413 fixed to the first sealing plate 412 is slidably arranged on the first guide rod 414, wherein a first spring 415 is provided on the first guide rod 414, one end of the first spring 415 is fixed to the first guide seat 413, and the other end is fixed to the end of the first guide rod 414; it can be explained that since the bottom opening end of the feeding box 4 is slidably fitted with the opening end on the feeding box 202, when the feeding box 4 moves toward the feeding box 202, based on the resistance of the top box wall of the feeding box 202 When the material feeding box 4 moves toward the material feeding box 202, the first sealing plate 412 and the material feeding box 4 are gradually misaligned to open the bottom opening of the material feeding box 4, and the rubber ingredients in the material feeding box 4 can fall into the material feeding box 202 through the bottom opening. During this process, the first sealing plate 412 drives the first guide seat 413 to slide on the first guide rod 414 to compress the first spring 415 and generate elastic force. When the material feeding box 4 moves toward the direction of the material storage box 3, the first spring 415 can drive the first sealing plate 412 to gradually return to its original position.

[0032] See also Figure 1-Figure 2 as well as Figure 4The lifting part includes a lifting plate 402 symmetrically fixedly arranged on the second sealing plate 401, and a support rod 403 is fixedly arranged on one end of the lifting plate 402 away from the second sealing plate 401. The support rod 403 is arranged on the side of the second sealing plates 401 on both sides away from each other. A U-shaped plate 405 is arranged on the feeding box 4, and the two side plates of the U-shaped plate 405 are respectively fixed to the support rod 403. A lifting rod 407 is also arranged on one side of the feeding box 4, and a sliding rod 407 is arranged on the lifting rod 407. 5 fixed guide plate 406, wherein the ends of the two side support rods 403 away from each other are respectively rotatably arranged with guide wheels 404, and the two sides of the mixing box 2 are respectively provided with first horizontal guide rails 306, and the first horizontal guide rail 306 is provided with an inclined guide rail 307 on the side facing the storage box 3, and the end of the inclined guide rail 307 away from the first horizontal guide rail 306 is fixed to the second horizontal guide rail 308, and the other end of the second horizontal guide rail 308 is fixed to the blanking box 301; it can be explained that, When the material feeding box 4 is moved to the position away from the material feeding box 202, the guide wheels 404 on both sides are located on the first horizontal guide rails 306. As the driving module drives the material feeding box 4 to move in the direction of the material storage box 3, when the material feeding box 4 and the material feeding box 202 just move to the misaligned state, the guide wheels 404 roll onto the inclined guide rails 307. As the material feeding box 4 continues to move, under the limiting action of the inclined guide rails 307, the guide wheels 404 drive the second sealing plate 401 to rise through the support rods 403 and the lifting plate 402. When the guide wheels 404 move to the position of the second horizontal guide rails 308, the second sealing plate 401 rises to the top open end of the material feeding box 4.

[0033] In this embodiment, please refer to Figure 1 and Figure 4The lifting rod 407 is fixed on the limit rod 416, and the diameter of the limit rod 416 is larger than the diameter of the lifting rod 407 to limit the guide plate 406 to prevent the second sealing plate 401 from continuing to fall when the second sealing plate 401 moves to the bottom open end of the feeding box 4, and the limit rod 416 is fixed to the U-shaped frame 408. The second adjusting portion includes a second guide rod 410 fixedly arranged on both sides of the feeding box 4, and a limit plate 409 fixed to the U-shaped frame 408 is slidably arranged on the second guide rod 410, wherein the second guide rod 410 is provided with a second spring 411, one end of the second spring 411 is fixed to the limit plate 409, and the other end is fixed to the end of the second guide rod 410; it can be explained that as the second sealing plate 401 rises to the top open end of the feeding box 4, when the feeding box 4 continues to move toward the storage box 3 When the material is moved in the opposite direction, based on the limiting effect of the wall of the blanking box 301, the second sealing plate 401 cannot continue to move, so that the second sealing plate 401 and the feed box 4 are misaligned, so as to open the top opening of the feed box 4, and the rubber raw material ingredients in the storage box 3 can be discharged into the feed box 4 through the blanking box 301 under the action of gravity. During this process, the limiting plate 409 can be synchronously driven to slide on the second guide rod 410 to compress the second spring 411 and generate elastic force. Correspondingly, when the blanking is completed, the feed box 4 moves in the direction away from the storage box 3, the second spring 411 can synchronously drive the second sealing plate 401 to reset. This embodiment does not require other servo drive equipment to drive the second sealing plate 401 to slide, which not only saves costs, but also has higher stability and synchronization.

[0034] When the feeding box 4 does not move to the bottom of the storage box 3, in order to prevent the rubber raw material ingredients in the storage box 3 from being discharged from the blanking box 301, in this embodiment, please refer to Figure 1-Figure 2 as well as Figure 6The third guide rod 304 is slidably provided with a second guide seat 303 fixed to the fifth sealing plate 302, and a third spring 305 is provided on the third guide rod 304. One end of the third spring 305 is fixed to the second guide seat 303, and the other end is fixed to the end of the third guide rod 304. It can be explained that in the initial state, the fifth sealing plate 302 is located just below the blanking box 301, which can achieve the effect of sealing the bottom open end of the blanking box 301. As the feeding box 4 moves toward the storage box 3, based on the restriction effect of the wall of the feeding box 4, the fifth sealing plate 302 can be pushed to slide toward one side of the blanking box 301, so that the bottom opening of the blanking box 301 is connected to the top opening of the feeding box 4, and the rubber raw material ingredients in the storage box 3 can fall into the feeding box 4 through the open end. During the sliding process of the fifth sealing plate 302, the second guide seat 303 is simultaneously driven to slide on the third guide rod 304 to compress the third spring 305 and generate elastic force. Correspondingly, when the feeding box 4 moves in the direction away from the storage box 3, the third spring 305 can drive the fifth sealing plate 302 to reset through the second guide seat 303.

[0035] See also Figure 4 The third adjusting portion includes a fourth guide rod 505 fixedly arranged on the outer wall of the air extraction box 5, and a third guide seat 504 fixed to the fourth sealing plate 503 is slidably arranged on the fourth guide rod 505, wherein a fourth spring 506 is provided on the fourth guide rod 505, one end of the fourth spring 506 is fixed to the third guide seat 504, and the other end is fixed to the fourth guide rod 505; it can be explained that when the air extraction box 5 moves toward the direction of the feeding box 202, based on the limiting effect of the box wall of the feeding box 202, the fourth sealing plate 503 stops moving, and a gap is generated between it and the air extraction box 5 The misalignment makes the bottom opening of the vacuum box 5 connected to the open end of the feeding box 202. During this process, the fourth sealing plate 503 synchronously drives the third guide seat 504 to slide on the fourth guide rod 505 to compress the fourth spring 506 and generate elastic force. Accordingly, when the vacuum box 5 moves in the direction away from the feeding box 202, the fourth spring 506 can synchronously drive the fourth sealing plate 503 to reset. This embodiment also does not require the use of other servo drive equipment to drive the fourth sealing plate 503 to slide, which not only saves costs, but also has higher stability and synchronization.

[0036] In this embodiment, please refer to Figure 3 and Figure 8Two groups of rollers 203 are arranged in a symmetrical rotation in the mixing box 2, and the two groups of rollers 203 are respectively fixed to the output ends of the servo motor 205 fixedly arranged on the outside of the mixing box 2. The servo motors 205 on both sides are respectively used to drive the rollers 203 to rotate synchronously toward the inside. Several groups of annular shearing kneaders 204 are evenly arranged on the rollers 203, and the annular shearing kneaders 204 on the rollers 203 on both sides are staggered. Specifically, after the raw materials of the automotive rubber sealing gasket fall into the mixing box 2, the two servo motors 205 respectively drive the rollers 203 on both sides to rotate synchronously to shear and mix the ingredients.

[0037] It should also be noted that after the raw materials of the automotive rubber sealing gasket fall into the mixing tube 1, they are extruded from the extrusion port at the end of the mixing tube 1. During the extrusion process, the mixed rubber can simultaneously seal the extrusion port to prevent exhaust gas from being discharged from the extrusion port.

[0038] Furthermore, during the mixing process, high-temperature air can be input into the mixing box 2 and the mixing tube 1 through the feed box 101 or the discharge box 201, which can not only improve the mixing effect, but also blow the waste gas generated into the exhaust box 5 during the exhaust process.

[0039] A mixing process of a raw material mixing device for processing automobile rubber sealing rings comprises the following steps: See also Figure 1-Figure 2 , S1, adding the automotive rubber sealing ring ingredients to be mixed into the storage box 3 for storage; S2, the driving module drives the feeding box 4 to move toward the storage box 3, and the top opening end of the feeding box 4 slides and fits with the bottom opening end of the blanking box 301; S3, when the second regulating part regulates the top opening end of the feeding box 4 to be in an open state, the ingredients in the storage box 3 are discharged into the feeding box 4 through the drop box 301 under the action of gravity; See also Figure 2-Figure 4 , S4, after the first blanking is completed, the driving module drives the feeding box 4 to move toward the mixing box 2. At this time, the second regulating part adjusts the top opening end of the feeding box 4 to be closed, and the first regulating part adjusts the bottom opening of the feeding box 4 to be in an open state. The ingredients in the feeding box 4 fall into the feeding box 202 under the action of gravity, and the automotive sealing ring rubber ingredients are mixed through the mixing box 2 and the mixing pipe 1; S5, during the blanking process, the lifting unit drives the second sealing plate 401 to descend to the bottom opening end of the feed box 4 to achieve a sealing effect to prevent the exhaust gas generated during mixing in the mixing box 2 from entering the feed box 4; S6. The driving module drives the feed box 4 to move toward the storage box 3 again. During the movement, the first adjustment part adjusts the first sealing plate 412 to gradually reset and seal the bottom opening of the feed box 4. After it is completely sealed, the lifting part drives the second sealing plate 401 to rise to the top opening end of the feed box 4 again.
