Description

Technical Field

[0001] This invention relates to the field of rubber processing technology, specifically to a rubber mixing and compounding production line with separate series connections. Background Technology

[0002] Rubber compounding is divided into internal mixing and open mixing, both of which aim to mechanically mix raw rubber with minor ingredients, compounding agents, and other components.

[0003] In open mixing, rubber is processed in an open environment, which facilitates slow and uniform feeding of rubber during the mixing process. In closed mixing, rubber is processed in a closed environment. During the rubber processing, rubber needs to be placed in open mixing equipment and closed mixing equipment one after the other. Manual assistance is required to move the rubber processed in the open mixing equipment to the closed mixing equipment. The movement is cumbersome and the rubber is easily contaminated during the movement. Summary of the Invention

[0004] The technical problem of this invention is to provide a rubber mixing and split series production line, which involves an automatic series production line that can move rubber from the upper open mill to the lower open mill without manual assistance, and automatically feeds and moves materials.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a rubber mixing production line consisting of an upper open mill and a lower internal mixer. Two sets of upper mixing rollers are rotatably mounted between the upper open mills, and two sets of lower mixing rollers are rotatably mounted between the lower internal mixers. The upper open mill is fixedly mounted above the lower internal mixers, with the upper mixing rollers positioned directly above the lower mixing rollers. Mounting frames are symmetrically mounted on the upper surface of the upper open mill, and rotating threaded rods are rotatably mounted between the mounting frames.

A fixed threaded component is rotatably installed on the upper end of the fixed plate. The fixed threaded component is threadedly connected to the movable threaded rod. The extension shaft is rotatably installed on both sides of the sealing box. A transmission gear is fixedly installed on both the extension shaft and the fixed threaded component. A transmission chain is sleeved on the transmission gear. A connecting shaft is provided on both sides of the extension shaft. A transmission assembly is provided between the connecting shafts on both sides and the extension shaft. The transmission assembly can drive the connecting shafts on both sides to rotate in opposite directions.

[0007] As a further embodiment of the present invention, the transmission assembly includes an intermediate gear, which is fixedly connected to the extension shaft. A side gear is fixedly installed on one side of the connecting shaft, and the side gear meshes with the intermediate gear. An intermediate wheel is fixedly installed on both the connecting shaft and the intermediate gear on the side away from the side gear, and a limiting belt is sleeved on the intermediate wheel.

[0008] As a further embodiment of the present invention, a side threaded rod is rotatably installed between the upper open mill and the positions corresponding to the two sides of the upper mixing roller. Small guide wheels are fixedly installed at both ends of the side threaded rod. A large gear is rotatably installed above the small guide wheels. A large guide wheel is fixedly installed on the large gear. A transmission belt is sleeved between the large guide wheel and the small guide wheel. A rotating assembly is provided on one side of the large gear. The rotating assembly can drive the large gear to rotate periodically.

[0009] As a further embodiment of the present invention, the rotating assembly includes an upper half-axle gear and a lower half-axle gear, both of which are rotatably mounted on the upper open mill. The teeth of both the upper and lower half-axle gears can mesh with the large gear. A driving gear is rotatably mounted on the upper open mill. An upper transmission member is provided between the driving gear and the upper half-axle gear. A driven gear is fixedly mounted on the lower half-axle gear, and the driven gear meshes with the driving gear.

[0010] As a further embodiment of the present invention, a movable threaded component is threadedly connected to the side threaded rod. A limit spring is fixedly installed at one end of the movable threaded component near the upper mixing roller, and a cutting needle is fixedly installed at the other end of the limit spring away from the movable threaded component. The front end of the cutting needle abuts against the upper mixing roller. A limit rod is provided on one side of the side threaded rod, and the limit rod is slidably connected to the movable threaded component.

[0011] As a further embodiment of the present invention, one end of the side threaded rod passes through the upper open mill and extends to one side of the upper open mill. A connecting plate is fixedly installed at the upper end of the upper open mill. The connecting plate is rotatably connected to the rotating threaded rod. A side transmission component is provided between the rotating threaded rod and the extension end of the side threaded rod. The feeding component is located between the two sets of upper mixing mills. A connecting hose is fixedly installed at the upper end of the feeding component.

[0012] As a further embodiment of the present invention, circulation boxes are fixedly installed on both sides of the upper open mill, and guide wheels are fixedly installed between the upper surface of the circulation boxes and the upper open mill. Multiple sets of transmission pipes are fixedly installed between the circulation boxes. Control panels are fixedly installed on both sides of the upper open mill. A guide pipe is fixedly installed at one end of the lower internal mixer, and a lower mounting plate is fixedly installed on the lower surface of the lower internal mixer.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. In this invention, after the rubber is mixed to a certain extent on the upper open mill, the cylinder drives the push plates to move towards each other. The push plates on both sides move closer to each other, pushing the rubber mixed on the upper open mill to the middle position of the upper mixing roller. At the same time as the push plates move, the cylinder drives the connecting shaft to rotate through the drive assembly. The rotation of the connecting shaft drives the sealing plate to rotate. The sealing plate rotates and opens to both sides, thereby opening the upper end of the sealing box. At this time, the rotation of the upper mixing roller on one side is closed. The rotation of the upper mixing roller on one side causes the mixed rubber material to move down and fall into the sealing box. This allows the mixed rubber material to automatically fall into the lower internal mixer at the lower end, avoiding the problem of continuous monitoring and auxiliary settings during rubber processing, avoiding the problem of wasted time and low efficiency caused by manual handling, reducing the contact between humans and rubber processing materials, and reducing the possibility of contamination of rubber processing materials.

[0015] 2. In this invention, the drive motor drives the active gear to rotate, which in turn drives the driven gear meshing with it to rotate. The driven gear rotates, which in turn drives the lower half-gear to rotate in the forward direction. The active gear rotates, which in turn drives the upper half-gear to rotate in the reverse direction via the upper transmission component. The upper and lower half-gears alternately mesh with the large gear, thereby driving the large gear to rotate periodically in both directions. The continuous rotation of the large gear in both directions drives the large guide wheel to rotate continuously in both directions. The rotation of the large guide wheel in both directions drives the lower guide wheel to periodically change its rotation direction via the transmission belt. The rotation of the small guide wheel drives the side threaded rod and the rotating threaded rod to periodically change their rotation direction. This causes the rotating threaded rod and the side threaded rod to rotate in both directions, driving the movable threaded component and the feeding component to move back and forth. The movement of the movable threaded component drives one end of the cutting needle, causing the cutting needle to cut away the rubber adhering to the surface of the upper mixing roller. This avoids the trouble of manual assistance in cutting during the processing, making the cutting more uniform, preventing the accumulation of rubber raw materials from affecting the operation of the upper mixing roller, and improving the automation of the device.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figures 1-7 This invention provides a technical solution: a rubber mixing production line consisting of an upper open mill 1 and a lower internal mixer 2. Two sets of upper mixing rollers are rotatably mounted between the upper open mill 1 and two sets of lower mixing rollers are rotatably mounted between the lower internal mixer 2. The upper open mill 1 is fixedly mounted above the lower internal mixer 2, with the upper mixing rollers directly above the lower mixing rollers. Mounting frames 7 are symmetrically mounted on the upper surface of the upper open mill 1, and rotating threaded rods 6 are rotatably mounted between the mounting frames 7. Feeding components 9 are threadedly connected to the rotating threaded rods 6. A cylinder 25 is mounted symmetrically. A pusher plate 24 is fixedly mounted on the free end of the cylinder 25. The pusher plate 24 is located between two sets of upper mixing rollers. A movable threaded rod 3 is fixedly mounted on the cylinder 25. A sealing box 41 is set outside the lower mixing roller. A sealing plate 16 is rotatably mounted on the upper surface of the sealing box 41. A connecting shaft 17 is fixedly mounted on both ends of the sealing plate 16. A drive assembly is set between the connecting shaft 17 and the movable threaded rod 3. The drive assembly can drive the sealing plate 16 to rotate while the cylinder 25 drives the pusher plate 24 to move closer to each other.

[0028] During operation, in the rubber mixing process, the rubber raw material is placed on the upper open mill 1. The upper mixing rollers between the upper open mill 1 rotate, causing the two sets of upper mixing rollers to rotate and squeeze the rubber raw material for mixing. During the mixing process, the rotating threaded rod 6 drives the feeding component 9 to move on it, so that the raw material in the feeding component 9 falls evenly and slowly into the space between the upper mixing rollers. This allows the raw material to be added to the rubber evenly and slowly, avoiding the trouble of manual feeding. After the rubber is mixed to a certain extent on the upper open mill 1, the cylinder 25 drives the push plates 24 to move towards each other. The push plates 24 on both sides move closer to each other, pushing the rubber mixed by the upper open mill 1 to the middle position of the upper mixing rollers. When the push plate 24 moves, the cylinder 25 drives the connecting shaft 17 to rotate via the drive assembly. The rotation of the connecting shaft 17 drives the sealing plate 16 to rotate, and the sealing plate 16 rotates to open to both sides, thereby opening the upper end of the sealing box 41. At this time, the upper mixing roller on one side is closed and rotates. The rotation of the upper mixing roller on one side causes the mixed rubber raw material to move down and fall into the sealing box 41, so that the mixed rubber raw material can automatically fall into the lower internal mixer 2 at the lower end. This avoids the problem of needing to continuously monitor and assist the settings during the rubber processing, avoids the problem of wasting time and low efficiency due to manual handling, reduces the contact between the manual and the rubber raw material, and reduces the possibility of the rubber raw material being contaminated.

[0029] In this invention, after the upper open mill 1 mixes the rubber to a certain extent, the cylinder 25 drives the push plates 24 to move towards each other. The push plates 24 on both sides move closer to each other, pushing the rubber mixed by the upper open mill 1 to the middle position of the upper mixing roller. At the same time as the push plates 24 move, the cylinder 25 drives the connecting shaft 17 to rotate through the drive assembly. The rotation of the connecting shaft 17 drives the sealing plate 16 to rotate. The sealing plate 16 rotates and opens to both sides, thereby opening the upper end of the sealing box 41. At this time, the rotation of the upper mixing roller on one side is closed. The rotation of the upper mixing roller on one side causes the mixed rubber material to move down and fall into the sealing box 41, so that the mixed rubber material can automatically fall into the lower internal mixer 2 at the lower end. This avoids the problem of needing to continuously monitor and assist in the rubber processing process, avoids the problem of wasting time and low efficiency due to manual handling, reduces the contact between the manual and the rubber processing material, and reduces the possibility of the rubber processing material being contaminated.

[0030] As a further embodiment of the present invention, the drive assembly includes a fixed plate 12 and an extension shaft 18. The fixed plate 12 is fixedly installed on both sides of the upper open mill 1. A fixed threaded component 21 is rotatably installed on the upper end of the fixed plate 12. The fixed threaded component 21 is threadedly connected to the movable threaded rod 3. The extension shaft 18 is rotatably installed on both sides of the sealing box 41. A transmission gear 20 is fixedly installed on both the extension shaft 18 and the fixed threaded component 21. A transmission chain 19 is sleeved on the transmission gear 20. A connecting shaft 17 is provided on both sides of the extension shaft 18. A transmission assembly is provided between the two connecting shafts 17 and the extension shaft 18. The transmission assembly can drive the two connecting shafts 17 to rotate in opposite directions.

[0031] During operation, cylinder 25 drives push plate 24 to move, simultaneously moving movable threaded rod 3. The linear movement of movable threaded rod 3 interacts with the threads on fixed threaded component 21. Under the action of movable threaded rod 3, fixed threaded component 21 rotates. This rotation drives transmission gear 20 on fixed threaded component 21 to rotate. Transmission gear 20, through transmission chain 19, drives lower transmission gear 20 to rotate. The lower transmission gear 20's rotation drives extension shaft 18 to rotate. The extension shaft 18's rotation, through transmission assembly, drives intermediate wheel 13 to rotate. Intermediate wheel 13's rotation, through limit belt, drives one-side connecting shaft 17 to rotate. The intermediate wheel 13's rotation, in turn, drives intermediate gear 22 to rotate. The intermediate gear 22's rotation then drives the side gear 39 meshing with it to rotate. The rotation of the side gear 39 drives the connecting shaft 17 on the other side to rotate in the opposite direction, thereby driving the connecting shafts 17 on both sides to rotate in opposite directions, so that the sealing plate 16 can open to both sides on the sealing box 41. The rotation of the connecting shaft 17 drives the sealing plate 16 to rotate. The rotation of the connecting shaft 17 to both sides drives the sealing plate 16, so that the sealing plate 16 is disengaged from the sealing box 41, thereby opening the upper end of the sealing box 41. When the rubber raw material is added into the sealing box 41, the cylinder 25 retracts, driving the push plate 24 to move back to both sides, and instructing the driving connecting shaft 17 to rotate in the opposite direction, driving the sealing plate 16 to rotate in the opposite direction, so that the sealing plate 16 rotates to seal the upper end of the sealing box 41, thereby allowing the rubber to be processed in a sealed processing environment in the lower internal mixer 2.

[0032] As a further embodiment of the present invention, the transmission assembly includes an intermediate gear 22, which is fixedly connected to an extension shaft 18. A side gear 39 is fixedly installed on a side connecting shaft 17, which meshes with the intermediate gear 22. An intermediate wheel 13 is fixedly installed on both the side connecting shaft 17 away from the side gear 39 and the intermediate gear 22. A limiting belt is sleeved on the intermediate wheel 13.

[0033] During operation, the extension shaft 18 rotates, driving the intermediate wheel 13 to rotate. The rotation of the intermediate wheel 13 drives the connecting shaft 17 on one side to rotate through the limit belt. The rotation of the intermediate wheel 13 drives the intermediate gear 22 to rotate. The rotation of the intermediate gear 22 drives the side gear 39 that meshes with it to rotate. The rotation of the side gear 39 drives the connecting shaft 17 on the other side to rotate in the opposite direction, thereby driving the connecting shafts 17 on both sides to rotate in opposite directions, so that the sealing plate 16 can be opened to both sides on the sealing box 41.

[0034] As a further embodiment of the present invention, a side threaded rod 26 is rotatably installed on both sides of the mixing roller between the upper open mill 1. Small guide wheels 32 are fixedly installed at both ends of the side threaded rod 26. A large gear 29 is rotatably installed above the small guide wheels 32. A large guide wheel 31 is fixedly installed on the large gear 29. A transmission belt 30 is connected to the large guide wheel 31 and the small guide wheel 32. A rotating component is provided on one side of the large gear 29. The rotating component can drive the large gear 29 to rotate periodically.

[0035] During operation, the drive motor drives the driving gear 28 to rotate, which in turn drives the driven gear 34 to rotate. The driven gear 34 then drives the lower half-axle gear 35 to rotate in the forward direction. The rotation of the driving gear 28, through the upper transmission component 33, drives the upper half-axle gear 27 to rotate in the reverse direction. The upper half-axle gear 27 and the lower half-axle gear 35 alternately mesh with the large gear 29, thereby driving the large gear 29 to rotate periodically in both directions. The continuous forward and reverse rotation of the large gear 29 drives the large guide wheel 31 to rotate continuously in both directions. The forward and reverse rotation of the large guide wheel 31, through the transmission belt 30, drives the lower guide wheel to periodically change its rotation direction. The rotation of the 32-axis drives the side threaded rod 26 and the rotating threaded rod 6 to periodically change their rotation direction, thereby causing the rotating threaded rod 6 and the side threaded rod 26 to continuously rotate in both directions, driving the movable threaded part 37 and the feeding part to move back and forth. This allows the feeding part to feed material evenly and slowly. In addition, the movement of the movable threaded part 37 drives one end of the cutting needle 36, causing the cutting needle 36 to cut the rubber adhering to the surface of the upper mixing roller. This avoids the trouble of manual assistance in cutting during the processing, making the cutting more uniform, preventing the accumulation of rubber raw materials from affecting the operation of the upper mixing roller, and improving the automation of the device.

[0036] In this invention, the drive motor drives the driving gear 28 to rotate, which in turn drives the driven gear 34 to rotate. The driven gear 34 then drives the lower half-axle gear 35 to rotate in the forward direction. The rotation of the driving gear 28 drives the upper half-axle gear 27 to rotate in the reverse direction via the upper transmission member 33. The upper half-axle gear 27 and the lower half-axle gear 35 alternately mesh with the large gear 29, thereby driving the large gear 29 to rotate periodically in both directions. The continuous rotation of the large gear 29 drives the large guide wheel 31 to rotate continuously in both directions. The rotation of the large guide wheel 31 drives the lower guide wheel periodically via the transmission belt 30. The rotation direction of the small guide wheel 32 is reversed, which drives the side threaded rod 26 and the rotating threaded rod 6 to periodically change their rotation direction. This causes the rotating threaded rod 6 and the side threaded rod 26 to rotate continuously in both directions, driving the movable threaded part 37 and the feeding part to move back and forth. The movement of the movable threaded part 37 drives one end of the cutting needle 36, which cuts the rubber adhering to the surface of the upper mixing roller. This avoids the trouble of manual assistance in cutting during the processing, makes the cutting more uniform, prevents the accumulation of rubber raw materials from affecting the operation of the upper mixing roller, and improves the automation of the device.

[0037] As a further embodiment of the present invention, the rotating assembly includes an upper half-axle gear 27 and a lower half-axle gear 35, both of which are rotatably mounted on the upper open mill 1. The teeth of both the upper half-axle gear 27 and the lower half-axle gear 35 can mesh with the large gear 29. A driving gear 28 is rotatably mounted on the upper open mill 1. An upper transmission member 33 is provided between the driving gear 28 and the upper half-axle gear 27. A driven gear 34 is fixedly mounted on the lower half-axle gear 35, and the driven gear 34 meshes with the driving gear 28.

[0038] As a further embodiment of the present invention, a movable threaded component 37 is threadedly connected to the side threaded rod 26. A limit spring 38 is fixedly installed at one end of the movable threaded component 37 near the upper mixing roller, and a cutting needle 36 is fixedly installed at the other end of the limit spring 38 away from the movable threaded component 37. The front end of the cutting needle 36 abuts against the upper mixing roller. A limit rod is provided on one side of the side threaded rod 26, and the limit rod is slidably connected to the movable threaded component 37.

[0039] As a further embodiment of the present invention, one end of the side threaded rod 26 extends through the upper open mill 1 to one side of the upper open mill 1. A connecting plate 11 is fixedly installed at the upper end of the upper open mill 1. The connecting plate 11 is rotatably connected to the rotating threaded rod 6. A side transmission component 10 is provided between the rotating threaded rod 6 and the extension end of the side threaded rod 26.
