Description

Technical Field

[0001] The present invention relates to the technical field of rubber mixing machines, and specifically to a rubber mixing machine for the production of open rubber tires. Background Art

[0002] A rubber mixing machine is a device specifically used for rubber processing, mainly used in processes such as rubber warm-up, sheet pressing, rubber breaking, plasticating, and mixing. Through two relatively rotating rollers, the rubber raw material is extruded, sheared, and mixed. The rubber raw material is placed between the two rollers. As the rollers rotate, the rubber is subjected to extrusion and shear forces, causing the molecular chains to break and rearrange, thereby achieving the purpose of plasticating and mixing.

[0003] During the rubber mixing process, the rubber compound is subjected to extrusion and shear forces between the rollers, but in some areas (such as the beginning of the wedge-shaped cross-section), closed return lines will form. The shear forces acting on these return lines are relatively small, affecting the rubber mixing effect. By cutting the rubber strips, it can prompt the rubber compound to move along the roller axis, continuously break these closed returns, thereby accelerating the rubber mixing effect and improving the rubber mixing efficiency. The cutting operation helps to disperse the compounding agents (such as vulcanizing agents, accelerators, fillers, etc.) in the rubber matrix more evenly, avoiding excessive or too low local concentrations and improving the uniformity of mixing.

[0004] However, in the existing rubber mixing machines during the rubber mixing process, the rubber is cut by mechanical cutting means. However, this cutting means cannot rewind the rubber roll into a cylinder and put it back into the rubber mixing rollers. Moreover, if manual intervention is used in mechanical cutting, it may cause injury to personnel. Therefore, its rubber mixing efficiency is low and does not meet the existing requirements. For this reason, we propose a rubber mixing machine for the production of open rubber tires. Summary of the Invention

A connecting folding rod is fixedly connected to the outer side of the triangular baffle plate, and the other end of the connecting folding rod is fixedly connected to the side wall of the limiting plate.

[0017] The present invention has the following beneficial effects:

[0018] 1. For the rubber mixing mill for the production of open rubber tires, when the telescopic outer shell is driven by the driving component to slide downward, the connected baffle plate descends synchronously. When the baffle plate descends to abut against the counter-rotating mixing roll group, the rubber roll is blocked by the baffle plate at this time. At the same time, since the sliding cutting component in front cuts the rubber roll, the rubber roll will be wound into a cylindrical shape. And because the rubber roll has a certain adhesiveness during the winding process, the cylindrical rubber roll will be adhered to the surface of the baffle plate. Through this design, the rubber roll can be quickly wound into a cylinder, and through the rotation of the tilting component, the cylindrical rubber roll is re-extruded and mixed by the counter-rotating mixing roll group in an inclined state. Through this design, it can be ensured that the rubber is subjected to more uniform heating and shearing effects inside the rubber mixing mill. This placement method helps the rubber material to be heated more evenly during the rubber mixing process, thereby accelerating the breakage and recombination of rubber molecular chains, improving the rubber mixing efficiency. At the same time, it helps the compounding agents (such as vulcanizing agents, accelerators, fillers, etc.) to be more evenly dispersed in the rubber matrix, and can also better discharge the air and other unwanted volatile gases inside the rubber, thereby reducing the bubbles and defects in the rubber and improving the physical properties and appearance quality of the product.

[0019] 2. The open rubber mixing machine for rubber tire production can ensure that the rubber roll will not fall off during the upward sliding and rotation of the telescopic shell through the design of the fixed component. During the downward sliding of the telescopic shell, it will interfere with and drive the sliding gear rod to slide downward in the fixed bottom shell, thereby driving the gear shaft engaged with the sliding gear rod to rotate. Through the rotation of the gear shaft, the pressure plate below rotates upward. At this time, the pressure plate will not affect the winding of the rubber roll. When the telescopic shell slides upward, the pressure plate rotates downward to clamp the wound rubber roll. Through this design, the wound rubber roll can be effectively prevented from falling off during the rotation and movement, thereby improving the stability of the operation of the material blocking component and the tilting component.

[0020] 3. In the open rubber mixing mill for rubber tire production, the width of the rubber roll is controlled by the position of the limit plate. Therefore, in order to ensure the rubber winding effect of the baffle assembly, the width of the baffle plate needs to be changed synchronously with the change of the limit plate. Therefore, through the design of the triangular groove and the triangular baffle plate, the width of the baffle plate is made the same as the width limited by the limit plate. The connecting folding rod is used to connect the limit plate and the triangular baffle plate, which effectively ensures that the adjustment of the limit plate and the adjustment of the baffle plate are carried out synchronously.

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Embodiment 1. The purpose of this embodiment is to promote the solution of the problem that the existing rubber mixing machine has a low rubber mixing effect on rubber rolls. Please refer to Figures 1 to 14 , a rubber mixing machine for open-type rubber tire production, including a support device 1. The support device 1 includes a bottom shell 11. A first vertical plate 12, a second vertical plate 13, and a third vertical plate 14 are fixedly connected to the upper surface of the bottom shell 11. Above the bottom shell 11, there is a rubber mixing main body 2. The rubber mixing main body 2 includes a pair of rotating mixing roller groups 23. Above the pair of rotating mixing roller groups 23, there is a material blocking component 3.

[0038] The rubber mixing main body 2 includes a driving motor 21 fixedly connected to the surface of the third vertical plate 14. The output end of the driving motor 21 is connected to a pair of rotating gear groups 22. On the side of the pair of rotating gear groups 22 away from the driving motor 21, there is a pair of rotating mixing roller groups 23. The pair of rotating mixing roller groups 23 are installed between the first vertical plate 12 and the second vertical plate 13. A first slide rail 24 and a second slide rail 26 are fixedly connected between the first vertical plate 12 and the second vertical plate 13. Two sliding cutting components 25 are slidably connected to the side wall of the first slide rail 24. Two limiting plates 27 are slidably connected to the side wall of the second slide rail 26. The limiting plates 27 are arranged above the pair of rotating mixing roller groups. The sliding cutting component 25 includes a slider 251 slidably connected to the side wall of the first slide rail 24. A cutting motor 252 is installed at the bottom of the slider 251. The output end of the cutting motor 252 is fixedly connected to a cutting knife 253 for cutting the colloid.

[0039] The design of the support device 1 provides support for the entire device. The driving motor 21 is used to drive the relative rotation of the pair of rotating gear groups 22. Through the relative rotation of the pair of rotating gear groups 22, the two mixing rollers in the pair of rotating mixing roller groups 23 rotate synchronously relative to each other (the above structure is the general structure of an open-type rubber mixing machine, and its working principle and effect are prior art, so this solution will not be described in detail). Through the sliding of the sliding cutting component 25 on the first slide rail 24, the colloid on the surface of the pair of rotating mixing roller groups 23 can be continuously cut (the cutting of the colloid by the sliding cutting component 25 and the sliding of the sliding cutting component 25 on the first slide rail 24 are prior art, so this solution will not be described in detail). The design of the second slide rail 26 and the limiting plates 27 can effectively limit the width of the colloid after being extruded (the sliding of the limiting plates 27 on the second slide rail 26 and the fixation of the limiting plates 27 are prior art, so this solution will not be described in too much detail).

[0040] The material blocking assembly 3 includes a telescopic housing 31 disposed above the counter-rotating mixing roller group 23 , a telescopic inner rod 32 is slidably connected in the telescopic housing 31 , and a material blocking plate 36 is rotatably connected to one side of the telescopic inner rod 32 .

[0041] A telescopic spring 33 is fixedly connected to the upper surface of the telescopic inner rod 32, and the other end of the telescopic spring 33 is fixedly connected to the telescopic outer shell 31. A T-shaped circular groove 34 is provided on the side wall of the telescopic inner rod 32, and a T-shaped connecting rod 35 is rotatably connected in the T-shaped circular groove 34. The end of the T-shaped connecting rod 35 away from the telescopic inner rod 32 is fixedly connected to a material baffle plate 36. A balance rod 37 is fixedly connected to the side of the telescopic outer shell 31 close to the second vertical plate 13, and the other end of the balance rod 37 is slidably connected in the upper and lower sliding grooves 38, which are provided on the surface of the second vertical plate 13.

[0042] The design of the balance bar 37 and upper and lower slide grooves 38 allows the telescopic housing 31 to slide only in the vertical direction, effectively ensuring the stability of the winding operation. The telescopic inner rod 32, with its telescopic spring 33, ensures that the retaining plate 36 resists the counter-rotating mixing roller set 23, thereby improving the winding effect of the rubber roll.

[0043] When the telescopic shell 31 is driven to slide downward by the driven component 4, the baffle plate 36 connected to it descends synchronously. When the baffle plate 36 descends to the point where it conflicts with the counter-rotating mixing roller group 23, the rubber roll is blocked by the baffle plate 36. At the same time, since the sliding cutting component 25 in the front cuts the rubber roll, the rubber roll will be rolled into a cylindrical shape, and since the rubber roll has a certain adhesion during the rolling process, the cylindrical rubber roll will be adhered to the surface of the baffle plate 36. Through this design, the rubber roll can be quickly rolled into a cylinder, and through the rotation of the tilting component 5, the cylindrical rubber roll is squeezed and mixed again by the counter-rotating mixing roller group 23 in a tilted state. Through this design, it can be ensured that the rubber is subjected to more uniform heating and shearing in the rubber mixer. This placement method helps the rubber material to be heated more evenly during the rubber mixing process, thereby accelerating the breakage and recombination of the rubber molecular chains and improving the rubber mixing efficiency. At the same time, it helps the compounding agents (such as vulcanizers, accelerators, fillers, etc.) to be more evenly dispersed in the rubber matrix, and can also better discharge the air and other unnecessary volatile gases inside the rubber, thereby reducing bubbles and defects in the rubber and improving the physical properties and appearance quality of the product.

[0044] One end of the telescopic housing 31 away from the balance rod 37 is provided with a driving assembly 4. The driving assembly 4 includes an installation groove 41 and a driving chute 42 opened in the first vertical plate 12. A driving rod 43 is slidably connected in the driving chute 42. One end of the driving rod 43 is fixedly connected with a driving spring 44, and the other end of the driving spring 44 is fixedly connected in the driving chute 42. One side of the driving rod 43 is connected with a driving gear 46 through a first one-way assembly 45. The upper surface of the driving gear 46 is fixedly connected with a first helical gear 47. The first helical gear 47 is meshed with a second helical gear 48. The second helical gear 48 is fixedly connected to one side of a turntable 49. The turntable 49 is rotatably connected to the surface of the first vertical plate 12. A track groove 410 is opened in the turntable 49. A slide rod 411 is slidably connected in the track groove 410. The other end of the slide rod 411 is fixedly connected to the side wall of the telescopic housing 31.

[0045] Multiple groups of first one-way assemblies 45 are provided. The first one-way assembly 45 includes a first one-way groove 451 opened in the side wall of the driving rod 43. A first one-way rotating shaft 452 is fixedly connected in the first one-way groove 451. The first one-way rotating shaft 452 is rotatably connected with a first one-way rotating tooth block 453 through a first one-way torsion spring 454. The first one-way rotating tooth block 453 is meshed with the driving gear 46.

[0046] When the sliding cutting assembly 25 slides left and right on the first slide rail 24, the sliding cutting assembly 25 located on one side of the first vertical plate 12 will intermittently contact the driving rod 43. At this time, the driving rod 43 will slide in the driving chute 42. Due to the existence of the driving spring 44, the driving rod 43 will quickly reset after each slide. At this time, because the first one-way assembly 45 is arranged in the driving rod 43, through the one-way driving of the first one-way assembly 45 on the driving gear 46, each touch of the sliding cutting assembly 25 will drive the driving gear 46 to rotate. The driving gear 46 rotates synchronously with the turntable 49 through the connection of the first helical gear 47 and the second helical gear 48. Therefore, when the first one-way assembly 45 cuts the rubber assembly, it will continuously drive the turntable 49 to rotate. At the same time, due to the design of the track groove 410 and the slide rod 411, when the turntable 49 rotates, it will control the telescopic housing 31 to move in the vertical direction. Through this driving, the baffle 36 can be effectively driven to wind the rubber raw material, providing a power basis for improving the mixing effect of the rubber.

[0047] The design of the No. 1 one-way component 45 is such that every time the driving rod 43 slides to the left, it will drive the driving gear 46 to rotate a certain angle. Due to the restriction of the No. 1 one-way groove 451, every time the driving rod 43 slides to the left, the No. 1 one-way rotating tooth block 453 is stuck in the No. 1 one-way groove 451 and cannot rotate. At this time, the driving gear 46 will be resisted by the No. 1 one-way rotating tooth block 453 and rotate. When the driving rod 43 slides to the right under the drive of the driving spring 44, the No. 1 one-way rotating tooth block 453 is not restricted by the No. 1 one-way groove 451 and will rotate into the No. 1 one-way groove 451. At this time, the No. 1 one-way rotating tooth block 453 does not drive the driving gear 46 at all, and the driving gear 46 will not rotate. Through this design, the one-way driving of the driving rod 43 on the driving gear 46 can be achieved, preventing the turntable 49 from reversing when the driving rod 43 is reset, thereby providing stability for the winding operation of the telescopic shell 31.

[0048] A tilting assembly 5 is provided between the material blocking plate 36 and the telescopic shell 31. The tilting assembly 5 includes a tooth plate 51 fixedly connected to the bottom of the telescopic shell 31. The tooth plate 51 is meshed with the deflection gear 53 through the second one-way assembly 52. The deflection gear 53 is fixedly connected to the side wall of the T-shaped connecting rod 35.

[0049] The No. 2 one-way component 52 is provided with multiple groups. The No. 2 one-way component 52 includes a No. 2 one-way groove 521 opened on the surface of the gear plate 51. The No. 2 one-way rotating shaft 522 is fixedly connected in the No. 2 one-way groove 521. The No. 2 one-way rotating shaft 522 is rotatably connected to the No. 2 one-way rotating gear block 523 through the No. 2 one-way torsion spring 524. The No. 2 one-way rotating gear block 523 is meshed and connected with the deflection gear 53.

[0050] When the telescopic outer shell 31 slides downward relative to the telescopic inner rod 32, the toothed plate 51 at the bottom of the telescopic outer shell 31 slides downward synchronously. At this time, due to the one-way design of the second one-way component 52 in the toothed plate 51, it will not drive the deflection gear 53 to rotate (the one-way driving principle of the second one-way component 52 is the same as that of the first one-way component 45, so it will not be described again). When the telescopic outer shell 31 slides upward relative to the telescopic inner rod 32, the deflection gear 53 is fixedly connected to the material baffle 36. Therefore, through this one-way drive, it can be realized that while the material baffle 36 slides upward, the wound rubber roll rotates, so that one end of the rubber roll contacts the counter-rotating mixing roll group 23 again and is refined by the counter-rotating mixing roll group 23. Through this design, the cylindrical rubber roll is extruded and mixed by the counter-rotating mixing roll group 23 again in an inclined state. Through this design, it can be ensured that the rubber is heated and sheared more evenly in the rubber mixing machine. This placement method helps the rubber material to be heated more evenly during the rubber mixing process, thereby accelerating the breakage and recombination of rubber molecular chains, improving the rubber mixing efficiency. At the same time, it helps the compounding agents (such as vulcanizing agents, accelerators, fillers, etc.) to be more evenly dispersed in the rubber matrix, and can also better discharge the air and other unwanted volatile gases inside the rubber, thereby reducing the air bubbles and defects in the rubber and improving the physical properties and appearance quality of the product.

[0051] Embodiment 2. The purpose of this embodiment is to facilitate the solution of the problem that the stability of the wound rubber roll adhering to the surface of the material baffle 36 is poor only due to the adhesion of the rubber material itself. This embodiment is an explanatory description based on Embodiment 1. Specifically, please refer to Figures 1 to 14 , a fixing component 6 is arranged in the material baffle 36. The fixing component 6 includes a fixed bottom shell 61 fixedly connected to the side wall of the material baffle 36. A sliding toothed rod 62 is slidably connected in the fixed bottom shell 61. The bottom of the sliding toothed rod 62 is fixedly connected to a return spring 63. The other end of the return spring 63 is fixedly connected in the fixed bottom shell 61. The telescopic outer shell 31 abuts against the upper part of the sliding toothed rod 62.

[0052] A cylindrical groove 64 is formed in the material baffle 36. A fixed shaft 65 is fixedly connected in the cylindrical groove 64. The outer side wall of the fixed shaft 65 is rotatably connected to a toothed shaft 66 through a fixed torsion spring 68. A pressing plate 67 is fixedly connected to the side wall of the toothed shaft 66. The toothed shaft 66 is meshed with the sliding toothed rod 62.

[0053] The design of the fixing assembly 6 can ensure that the rubber roll will not fall off during the upward sliding and rotation of the telescopic shell 31. During the downward sliding of the telescopic shell 31, it will interfere with and drive the sliding gear rod 62 to slide downward in the fixed bottom shell 61, thereby driving the gear shaft 66 engaged with the sliding gear rod 62 to rotate. Through the rotation of the gear shaft 66, the pressure plate 67 below is rotated upward (the state shown in the figure is the state after the telescopic shell 31 slides downward one end distance relative to the telescopic inner rod 32). At this time, the pressure plate 67 will not affect the reeling work of the rubber roll. When the telescopic shell 31 slides upward, the pressure plate 67 rotates downward to clamp the reeled rubber roll. Through this design, the reeled rubber roll can be effectively prevented from falling off during the rotation and movement, thereby improving the stability of the operation of the material blocking assembly 3 and the tilting assembly 5. The design of the fixed torsion spring 68 ensures the squeezing force of the pressure plate 67 on the rubber roll when clamping the rubber roll, further ensuring the stability of the rubber roll.

[0054] Example 3, this example is intended to promote the solution of the problem that the length of the baffle plate 36 needs to be adjusted according to the sliding of the limit plate due to the limitation of the limit plate 27. This example is an explanation made on the basis of Example 2. For details, please refer to Figures 1 to 14 , a telescopic assembly 7 is provided on both sides of the baffle plate 36, and the telescopic assembly 7 includes a triangular groove 71 opened on both sides of the baffle plate 36, a triangular baffle plate 72 is slidably connected in the triangular groove 71, and a connecting folding rod 73 is fixedly connected to the outer side of the triangular baffle plate 72, and the other end of the connecting folding rod 73 is fixedly connected to the side wall of the limit plate 27

[0055] The width of the rubber roll is controlled by the position of the limit plate 27. Therefore, in order to ensure the rolling effect of the baffle assembly 3 on the rubber, the width of the baffle plate 36 needs to change synchronously according to the change of the limit plate 27. Therefore, through the design of the triangular groove 71 and the triangular baffle plate 72, the width of the baffle plate 36 is the same as the width limited by the limit plate 27. The connecting folding rod 73 is used to connect the limit plate 27 and the triangular baffle plate 72, which effectively ensures that the adjustment of the limit plate 27 and the adjustment of the baffle plate 36 are carried out synchronously.
