Description

Technical Field

[0001] The present invention relates to the technical field of rubber mixing machines, and particularly relates to an automatic rubber turning mechanism for an open rubber mixing machine. Background Art

[0002] The main working components of an open rubber mixing machine are two hollow rollers or drilled rollers that rotate inwardly in opposite directions. The roller on the operator's side is called the front roller, which can be moved horizontally forward and backward manually or electrically to adjust the roller gap to meet the operation requirements; the rear roller is fixed and cannot be moved forward and backward. The two rollers are generally of the same size and rotate relative to each other at different speeds. The raw rubber or rubber compound is rolled into the gap between the two rollers as the rollers rotate and is subjected to strong shearing action to achieve the purpose of plasticizing or mixing. During the rubber mixing process, it is necessary to turn the rubber to make the rubber compound evenly heated. Traditionally, manual labor is used to cut and turn the rubber compound, resulting in a low degree of automation. At the same time, there are certain safety hazards in manual rubber turning during the operation of the rollers. Currently, the rubber turning mechanism usually uses two relatively moving clamping plates to squeeze the rubber body to achieve rubber turning. However, in the early stage of the rubber compound forming, the viscosity between the rubber compounds is small and the rubber body has not been formed yet. During the rubber turning process, the rubber compound will fall off, and manual labor is still required to re-feed the fallen rubber compound. There is still room for improvement in its degree of automation. Therefore, we propose an automatic rubber turning mechanism for an open rubber mixing machine, which can further reduce the participation of manual labor and solve the problem of rubber compound falling off during the rubber turning process.

[0021] (III) Beneficial effects

[0022] Compared with the known public technology, the present invention provides an automatic rubber turning mechanism for an open mill, which has the following beneficial effects:

[0023] In the present invention, the pressing component can drive the rubber turning driving component and two clamping plates to lift, so that the clamping plates are pressed against the tops of the front roller and the rear roller of the open mill.

The material cutting plate and the centralized scraper descend along with the rubber turning driving component and the clamping plates. The material cutting plate blocks the rubber on the rubber receiving and conveying component. When the rubber turning driving component drives the two clamping plates to approach each other, the centralized scraper moves along with the clamping plates and pushes the rubber in the aggregate tank to the middle position, i.e., above the rubber lifting plate. The lifting plate driving component drives the rubber lifting plate to rise. During this process, the centralized scraper and the material cutting plate shield the rubber on the rubber lifting plate. At the same time, the rubber lifting plate can scrape off the rubber on the surface of the centralized scraper. The feeding upper roller component can push the rubber on the rubber lifting plate to the tops of the front roller and the rear roller for rubber mixing. Compared with the above-mentioned prior art, this solution can further reduce the participation of manual labor, realize automatic rubber turning, and solve the problem of rubber dropping during the rubber turning process.

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] Example 1, please refer to Figures 1 to 5 An automatic rubber turning mechanism of an open rubber mixing mill includes two clamping plates 4, a rubber turning driving component 100, a rubber receiving and conveying component 300, a rubber preliminary collecting component 400, a rubber concentrating component 500, a rubber lifting component 600, a feeding upper roller component 800 and a material cutting plate 7.

[0042] See also Figure 1 and Figure 2, the main working components of the open mill 1 are two hollow or drilled rollers that rotate in opposite directions inward. The roller on the operator's side is called the front roller 2, which can be moved horizontally forward and backward manually or electrically to adjust the roller gap to meet the operating requirements; the rear roller 3 is fixed and cannot be moved forward and backward. The two rollers are generally of the same size and rotate relative to each other at different speeds. The raw rubber or rubber compound is drawn into the gap between the two rollers as the rollers rotate and is subjected to strong shearing action to achieve the purpose of plasticizing or mixing.

[0043] Please refer to Figure 5 , the rubber turning drive component 100 includes a moving track 101, a rubber turning drive motor 102, and a bidirectional screw 103. The moving track 101 is installed on the top of the open mill 1 through a pressing component 200. The clamping plate 4 and the moving track 101 are in sliding fit. The bidirectional screw 103 is rotatably installed inside the moving track 101. The rubber turning drive motor 102 is installed on the moving track 101. The bidirectional screw 103 is fixedly installed at the output end of the rubber turning drive motor 102. The two clamping plates 4 are symmetrically arranged around the bidirectional screw 103. The two clamping plates 4 are respectively in threaded fit with the two threaded sections of the bidirectional screw 103. By driving the bidirectional screw 103 to rotate through the rubber turning drive motor 102, and through the sliding fit between the clamping plate 4 and the moving track 101 and the threaded fit between the clamping plate 4 and the bidirectional screw 103, the relative movement of the two clamping plates 4 can be realized. When the two clamping plates 4 approach each other, the rubber compound between the front roller 2 and the rear roller 3 can be extruded, so that the rubber compound rolls over to achieve the rubber turning operation;

[0044] Please refer to Figure 1 and Figure 2 , the pressing component 200 includes a mounting plate 201 and a pressing electric cylinder 202. The mounting plate 201 is fixedly installed on the top of the open mill 1. The pressing electric cylinder 202 is installed on the mounting plate 201. The moving track 101 is fixedly installed at the output end of the pressing electric cylinder 202. By driving the pressing electric cylinder 202, the moving track 101 and the clamping plate 4 can be lifted. When rubber turning is required, the clamping plate 4 is pressed on the top of the front roller 2 and the rear roller 3 for rubber turning operation. When rubber turning is not required, the clamping plate 4 is lifted away from the front roller 2 and the rear roller 3 to reduce the interference with rubber mixing. A plurality of sliding columns 5 are connected between the mounting plate 201 and the open mill 1. The moving track 101 and the sliding columns 5 are in sliding fit. The stability of the moving track 101 can be improved through the sliding fit between the sliding columns 5 and the moving track 101, so as to ensure the stability of the clamping plate 4, etc.

[0045] Please refer to Figure 4The rubber material receiving and conveying component 300 includes a plurality of transmission rollers 301, a conveyor belt 302 and a conveying motor 303. The transmission rollers 301 are rotatably installed inside the open rubber mixer 1. The conveyor belt 302 is transmission-connected to the periphery of the plurality of transmission rollers 301. The conveyor belt 302 is located below the front roller 2 and the rear roller 3 of the open rubber mixer 1. The conveying motor 303 is installed on the open rubber mixer 1 and is used to drive the corresponding transmission rollers 301 to rotate. The rubber material falling from the front roller 2 and the rear roller 3 falls on the surface of the conveyor belt 302. The conveying motor 303 can drive the corresponding transmission rollers 301 to rotate, thereby driving the conveyor belt 302 to operate. The top of the conveyor belt 302 moves from front to rear to convey the rubber material to the rubber material preliminary collecting component 400 located at the rear side.

[0046] For additional information, please refer to Figure 1 and Figure 4 The conveyor belt 302 is inclined, and the rear side of the conveyor belt 302, that is, the side close to the collecting trough 401, is of lower height, which can make the rubber material have a tendency to slide backward under the action of its own weight, so as to facilitate the collection of the rubber material. At the same time, a baffle plate 6 is arranged above the front side of the conveyor belt 302, and the baffle plate 6 is inclined. The bottom of the baffle plate 6 is in contact with the conveyor belt 302, and the top of the baffle plate 6 is in an outwardly opened state, which can shield the front side of the conveyor belt 302, and prevent the fallen rubber material from splashing from the front side of the conveyor belt 302, thereby reducing the waste of rubber material.

[0047] See also Figure 2 and Figure 3 The rubber preliminary collecting component 400 includes a collecting trough 401 and a conveyor belt scraper 402. The collecting trough 401 is installed on the rear side of the open rubber mixer 1, and the conveyor belt scraper 402 is installed on the top of the collecting trough 401. The top of the conveyor belt scraper 402 is in contact with the conveyor belt 302. The end of the conveyor belt scraper 402 away from the conveyor belt 302 is flush with the inner wall of the collecting trough 401. The top tip of the conveyor belt scraper 402 is in contact with the conveyor belt 302, and the rubber on the top of the conveyor belt 302 can be scraped off. The scraped rubber falls into the inside of the collecting trough 401 for collection, preparing to be sent back to the top of the front roller 2 and the rear roller 3 later.

[0048] See also Figure 2 and Figure 5, the rubber compound concentrating component 500 includes two concentrating scrapers 501. The two concentrating scrapers 501 are respectively fixedly connected to the corresponding clamping plates 4. The concentrating scraper 501 is in sealed sliding fit with the aggregate chute 401 and the conveyor belt scraper 402. The concentrating scraper 501 and the clamping plate 4 move synchronously. When the clamping plate 4 and the concentrating scraper 501 are in a higher position, the clamping plate 4 does not interfere with the rubber mixing, and the concentrating scraper 501 does not interfere with the collection of the rubber compound by the aggregate chute 401. When the clamping plate 4 descends to contact the front roller 2 and the rear roller 3, the bottom end of the concentrating scraper 501 contacts the inner bottom wall of the aggregate chute 401. Initially, the two clamping plates 4 are in a state of moving away from each other, and the concentrating scrapers 501 are also in a state of moving away from each other. The clamping plate 4 pushes the rubber compound on the tops of the front roller 2 and the rear roller 3 to the middle position, and the concentrating scraper 501 also pushes the rubber compound inside the aggregate chute 401 to the middle position. At the same time, the rubber compound adhered to the surface of the conveyor belt scraper 402 can be scraped off and pushed to the middle position of the aggregate chute 401.

[0049] Please refer to Figure 2 and Figure 3 , the rubber compound lifting component 600 includes a rubber compound lifting plate 601 and a lifting plate driving assembly 700 for driving the rubber compound lifting plate 601 to lift and lower. A plate groove matching the rubber compound lifting plate 601 is opened on the aggregate chute 401. The rubber compound lifting plate 601 is located at the middle position of the aggregate chute 401, and the top end of the rubber compound lifting plate 601 is flush with the inner bottom wall of the aggregate chute 401. The front end of the rubber compound lifting plate 601 is flush with the front inner wall of the aggregate chute 401;

[0050] Please refer to Figure 3 , the lifting plate driving assembly 700 includes a lifting motor 701 and a lead screw 702. The lead screw 702 is rotatably installed at the top of the aggregate chute 401. A limit rod 703 is fixedly connected to the top of the aggregate chute 401. The lead screw 702 is fixedly installed at the output end of the lifting motor 701. A nut matching the lead screw 702 is installed on the rubber compound lifting plate 601. The limit rod 703 is in sliding fit with the rubber compound lifting plate 601;

[0051] By driving the lead screw 702 to rotate through the lifting motor 701, through the cooperation of the nut and the lead screw 702 and the limiting effect of the limit rod 703 on the rubber compound lifting plate 601, the lifting and lowering of the rubber compound lifting plate 601 can be realized. Initially, the rubber compound lifting plate 601 is at the lowest position, that is, flush with the inner bottom wall of the aggregate chute 401. The concentrating scraper 501 pushes the rubber compound in the aggregate chute 401 to the top of the rubber compound lifting plate 601. The two concentrating scrapers 501 and the two clamping plates 4 are in a state of approaching each other. The rubber compound lifting plate 601 rises. The concentrating scraper 501 shields and protects the left and right sides of the rubber compound lifting plate 601 to prevent the rubber compound from falling. At the same time, the rubber compound lifting plate 601 scrapes off the rubber compound adhered to the surface of the concentrating scraper 501. The rubber compound adhered to the middle position of the conveyor belt scraper 402 is scraped off during the rising process of the rubber compound lifting plate 601.

[0052] Please refer to Figure 3 Figure, the feeding upper roller component 800 includes a feeding electric cylinder 801, a pushing plate 802, and a sliding chute 803. The feeding electric cylinder 801 is installed on the top of the rubber material lifting plate 601. The pushing plate 802 is fixedly installed at the output end of the feeding electric cylinder 801. The pushing plate 802 and the rubber material lifting plate 601 are in sliding fit. When the rubber material lifting plate 601 rises above the front roller 2 and the rear roller 3, initially, the pushing plate 802 is at the rear side to block and protect the rubber material on the rubber material lifting plate 601. The sliding chute 803 is inclined and arranged above the rear roller 3, and the front side of the sliding chute 803 is the side with a lower height. By driving the pushing plate 802 to move forward through the feeding electric cylinder 801, the rubber material on the rubber material lifting plate 601 can be pushed into the interior of the sliding chute 803. The lower end with a lower height of the sliding chute 803 is above the middle position between the front roller 2 and the rear roller 3, so that the rubber material can slide between the front roller 2 and the rear roller 3 for rubber mixing.

[0053] Please refer to Figures 2 to 5 Figure, the cutting plate 7 is fixedly connected to the moving track 101. The rear end of the cutting plate 7 contacts the centralized scraper 501, and the bottom end of the cutting plate 7 contacts the rear side of the conveyor belt 302. The cutting plate 7 and the moving track 101 move synchronously. When the pressing electric cylinder 202 drives the clamping plate 4 and the centralized scraper 501 to descend, the cutting plate 7 descends and contacts the conveyor belt 302 to block the rubber material on the conveyor belt 302, thereby preventing the rubber material from continuing to fall into the aggregate tank 401. Then, the centralized scraper 501 centralizes the rubber material inside the aggregate tank 401. The rubber material lifting plate 601 drives the centralized rubber material to rise and send it back to the top of the front roller 2 and the rear roller 3. The front end of the rubber material lifting plate 601 contacts the cutting plate 7. During the rising process of the rubber material lifting plate 601, the cutting plate 7 shields and protects the front side of the rubber material lifting plate 601. The rubber material lifting plate 601 stops rising when it is flush with the cutting plate 7. At this time, the feeding electric cylinder 801 drives the pushing plate 802 to push the rubber material on the rubber material lifting plate 601 forward. When the rubber material lifting plate 601 descends to be flush with the inner bottom wall of the aggregate tank 401, the pressing electric cylinder 202 drives the clamping plate 4 and the centralized scraper 501 to rise, the cutting plate 7 rises, and the rubber material on the top of the conveyor belt 302 continues to fall into the aggregate tank 401 for subsequent centralization, lifting, and sending-back operations.

[0054] Example 2, please refer to Figures 2 to 3 Figure, on the basis of Example 1, a rotating frame 8 is fixedly installed on the top of the pushing plate 802. A driving roller 9 is rotatably installed inside the rotating frame 8. A plurality of high-pressure nozzles 10 are installed on the driving roller 9. The plurality of high-pressure nozzles 10 are interconnected through a communicating pipe. The communicating pipe is connected to an air supply pipe. A nozzle driving assembly for driving the driving roller 9 and the plurality of high-pressure nozzles 10 to rotate is installed on the pushing plate 802;

[0055] See also Figures 2 to 3 The nozzle drive assembly includes a nozzle drive motor 11, which is installed on the top of the push plate 802. The output shaft of the nozzle drive motor 11 is connected to the drive roller 9 through a sprocket chain. The air supply pipe is connected to an external air supply device. The external air supply device supplies air to multiple high-pressure nozzles 10, and high-pressure gas is sprayed through the high-pressure nozzles 10 to blow the rubber material. The drive roller 9 can be driven to rotate through the transmission action of the nozzle drive motor 11 and the sprocket chain, so as to adjust the blowing angle of the multiple high-pressure nozzles 10. Initially, the high-pressure nozzle 10 faces the top of the push plate 802, and the nozzle drive motor 11 drives the drive roller 9 to rotate, driving the bottom of the multiple high-pressure nozzles 10 to rotate forward, blowing off the rubber material on the surface of the push plate 802, and then blowing the rubber material on the surface of the rubber lifting plate 601 forward to the inside of the sliding trough 803, and then blowing the rubber material on the sliding trough 803 to the top of the front roller and the rear roller for rubber mixing.
