Description

Technical Field

[0001] This invention relates to the field of internal mixer manufacturing technology, and in particular to the blade shaft device of a meshing and cooling type internal mixer. Background Technology

[0002] The impeller assembly of a bite-cooled internal mixer is one of the key components of the internal mixer. It typically consists of a rotor shaft, cooling channels, sealing devices, bearings, and support structures. During operation, the rotor shaft rotates at high speed driven by a motor. Material is fed into the mixing chamber, and as the rotor shaft rotates, the material is subjected to intense shearing, compression, and agitation by the protruding ridges on the shaft, rapidly mixing and heating up. Simultaneously, the cooling medium circulates within the cooling channels, carrying away the heat generated by the rotor shaft through heat exchange, maintaining the rotor shaft within a suitable temperature range, thereby ensuring the stability of the mixing process and the consistency of product quality.

[0003] However, cooling channels alone are not enough to ensure that the rotor shaft is always kept within a suitable temperature range. When the flow rate of the cooling medium is insufficient, the heat exchange efficiency is low and heat is easily trapped. There may be uneven flow in the cooling channels (such as insufficient local turbulence or dead zones), resulting in insufficient heat dissipation in some areas. In addition, the contact thermal resistance between the cooling channels and the heat-generating components (such as air gaps or poor thermal conductivity of materials) will also reduce the heat dissipation efficiency. Summary of the Invention

[0004] Therefore, it is necessary to provide a meshing cooling type internal mixer impeller device that can further improve heat dissipation efficiency in response to the above-mentioned technical problems.

[0005] The interlocking cooling type internal mixer impeller device provided by the present invention includes two rotating shafts, which are driven by gear meshing, and further includes: The blade is fixedly sleeved on the outside of the rotating shaft, with a spiral ridge on the outside and an annular groove on the inside, and multiple heat dissipation holes at both ends. An annular pipe is fixedly sleeved on the outside of the rotating shaft and located inside the annular groove; The water inlet pipe is fixedly installed inside the rotating shaft and is interconnected with the annular pipe. The water outlet pipe is located inside the rotating shaft and is interconnected with the annular pipe. A fixing plate is axially and symmetrically fixed on both sides of the annular groove, and its two ends are fixedly connected to the inner wall of the blade. The sliding blocks are axially and symmetrically slidably disposed at both ends of the fixed plate; A swing plate is movably mounted within the sliding block; A drive component, located on the sliding block, is used to drive the swing plate to swing.

[0006] In one embodiment, the drive assembly includes a fixed block that is fixedly connected to the sliding block. The fixed block has a groove at its center and is located on one side of the swing plate. A drive rack is laterally movably disposed inside the fixed block. An incomplete gear is fixedly sleeved on the outside of the swing plate, and the drive rack meshes with the incomplete gear for transmission.

[0007] In one embodiment, a rotating rod is rotatably disposed within the groove, a rotating ring is movably sleeved on the outer side of the rotating rod, a ball is disposed at the bottom of the driving rack, the end of the ball away from the driving rack is fitted with the inside of the rotating ring, a positioning ring is movably sleeved on the outer side of the rotating rod located on one side of the rotating ring, and a connecting plate is movably disposed between the positioning ring and the rotating ring.

[0008] In one embodiment, a vertical plate is fixedly provided on one side of the fixed block, and a round rod is movably provided through the center of the vertical plate. The round rod and the rotating rod are driven by bevel gear meshing. A movable gear is fixedly sleeved on the other end of the round rod. A fixed rack is fixedly provided on the fixed plate. The fixed rack movably passes through the fixed block and meshes with the movable gear.

[0009] In one embodiment, a positioning block is fixedly disposed on one side of the fixing block, a movable rod is movably disposed through the positioning block, a movable ring is fixedly disposed at one end of the movable rod, and the movable ring movably abuts against the positioning ring.

[0010] In one embodiment, a positioning plate is fixedly sleeved on the outside of the movable rod, and a lead screw is movably inserted through the positioning block below the movable rod. A sleeve is movably sleeved on the outside of the lead screw, and the sleeve is fixedly connected to the positioning plate.

[0011] In one embodiment, a cylinder is fixedly provided at the end of the lead screw away from the sleeve, and an arc-shaped groove is provided on the cylinder. A limit rod is fixedly provided on one side of the fixed plate, and the limit rod slides and fits against the arc-shaped groove.

[0012] In one embodiment, the swing plate has multiple through holes that can be moved through it.

[0013] In one embodiment, the swing plate has a slot, and a movable plate is movably disposed in the slot. The movable plate has a number of circular holes that are the same as the number of through holes.

[0014] In one embodiment, a fixed rod is movably disposed inside the swing plate, and both ends of the fixed rod are fixedly connected to the sliding block. A circular ring is fixedly sleeved on the outside of the fixed rod, and a circular groove and an inclined groove are formed on the circular ring, which are connected to each other. A guide rod is fixedly disposed on one side of the swing plate, and the end of the guide rod away from the swing plate is slidably connected to the circular groove and the inclined groove.

[0015] The aforementioned interlocking cooling type internal mixer impeller device achieves the reciprocating oscillation of the swing plate through the cooperation of multiple components such as a rotating rod, rotating ring, sphere, drive rack, and incomplete gear. This enhances the agitation effect on hot air, strengthens turbulence, accelerates the transfer of heat from the center of the rotating shaft to the heat dissipation holes, and promotes the discharge of heat from inside the blades. The tilt angle of the rotating ring can be adjusted through the cooperation of multiple components such as a lead screw, sleeve, moving rod, positioning plate, moving ring, and positioning ring, thereby adjusting the swing amplitude of the swing plate. The through-hole and the round hole are aligned when the swing plate approaches the heat dissipation holes. During the swing of the plate, air passes through the through-hole, forming local turbulence, accelerating heat transfer, and promoting heat discharge. Attached Figure Description

[0024] The following is combined Figures 1-10 The present invention describes the bite-cooling type internal mixer blade shaft device.

[0025] like Figures 1-7 As shown, in one embodiment, the meshing cooling type internal mixer blade assembly includes two rotating shafts 1, which are driven by gear meshing, and further includes: The blade 2 is fixedly sleeved on the outside of the rotating shaft 1. It has a spiral protrusion 3 on the outside and an annular groove 201 on the inside. Multiple heat dissipation holes 202 are opened at both ends. The annular pipe 4 is fixedly sleeved on the outside of the rotating shaft 1 and located inside the annular groove 201; Water inlet pipe 5 is fixedly installed inside the rotating shaft 1 and is connected to the annular pipe 4; The water outlet pipe 6 is located inside the rotating shaft 1 and is connected to the annular pipe 4. The fixing plate 7 is axially and symmetrically fixed on both sides of the annular groove 201, and its two ends are fixedly connected to the inner wall of the blade 2. Sliding blocks 10 are axially symmetrically slidably disposed at both ends of the fixed plate 7; The swing plate 11 is movably installed within the sliding block 10; The drive component 8 is located on the sliding block 10 and is used to drive the swing plate 11 to swing.

[0026] Specifically, the device is installed inside the hopper of the internal mixer. One end of the rotating shaft 1 is rotatably connected to the inner wall of the hopper, while the other end extends through the inner wall on the other side. Driven by gears, the two rotating shafts 1 and blades 2 rotate in opposite directions. The spiral protrusions 3 on the blades 2 agitate the rubber compound, generating a large amount of heat during the agitation process. Cooling medium is introduced through the inlet pipe 5, enters the annular pipe 4, and then exits through the outlet pipe 6, carrying away the heat generated by the rotating shafts 1 and blades 2 during high-speed rotation and friction with the material. This effectively controls the temperature and prevents premature vulcanization, scorching, or performance degradation of the material due to excessively high temperatures. The blades 2 rotate simultaneously... The sliding blocks 10 move along the fixed plate 7 to both sides and then return to the initial position. The two sliding blocks 10 on one side of the fixed plate 7 first move away from each other along the annular groove 201 and then move closer to each other back to the initial position. The sliding blocks 10 can be designed to be driven by a motor. During the process of the sliding blocks 10 moving away, they will drive the swing plate 11 to move towards the heat dissipation hole 202. During the movement, the swing plate 11 is driven to swing back and forth by the drive component 8. The swinging action of the swing plate 11 disturbs the air, enhances the turbulence effect, and accelerates the transfer of heat from the middle of the rotating shaft 1 to the heat dissipation hole 202. In addition, the movement of the swing plate 11 will also "sweep" the heat towards the heat dissipation hole 202, improving the heat dissipation efficiency.

[0027] See Figures 5-7 As shown, in this embodiment, the drive assembly 8 includes a fixed block 81, which is fixedly connected to the sliding block 10. The fixed block 81 has a groove 82 in the center and is located on one side of the swing plate 11. A drive rack 83 is transversely movably disposed inside the fixed block 81. An incomplete gear 9 is fixedly sleeved on the outside of the swing plate 11. The drive rack 83 meshes with the incomplete gear 9 for transmission.

[0028] Specifically, when the sliding block 10 moves laterally back and forth relative to the fixed plate 7, the fixed block 81 moves synchronously together. During the movement, the sliding block 10 moves laterally back and forth relative to the groove 82, driving the rack 83. The laterally back and forth movement of the rack 83 will drive the incomplete gear 9 to rotate back and forth, thereby driving the swing plate 11 to swing back and forth. This can improve the stirring effect of hot air, enhance the turbulence effect, accelerate the transfer of heat from the middle of the rotating shaft 1 to the heat dissipation hole 202, and promote the discharge of heat inside the blade 2.

[0029] See Figures 5-7 As shown, in this embodiment, a rotating rod 12 is rotatably arranged inside the groove 82, and a rotating ring 13 is movably sleeved on the outside of the rotating rod 12. A ball 14 is provided at the bottom of the drive rack 83. The end of the ball 14 away from the drive rack 83 is in contact with the inside of the rotating ring 13. A positioning ring 15 is movably sleeved on the outside of the rotating rod 12 on one side of the rotating ring 13. A connecting plate 16 is movably arranged between the positioning ring 15 and the rotating ring 13.

[0030] Specifically, rotating the rotating rod 12 causes the rotating ring 13 to rotate. The rotating ring 13 is inclined and has a vertical groove inside. The rotating rod 12 moves through the vertical groove. Therefore, the rotation of the rotating rod 12 causes the rotating ring 13 to rotate and swing back and forth. Through the limiting effect of the ball 14, the rotating ring 13 also causes the drive rack 83 to move laterally back and forth relative to the fixed block 81, thereby causing the incomplete gear 9 and the swing plate 11 to swing back and forth, enhancing the heat dissipation effect. The rotation of the rotating ring 13, through the connection relationship of the connecting plate 16, causes the positioning ring 15 to rotate around the rotating rod 12. The positioning ring 15 will not deviate during rotation.

[0031] See Figure 4 and Figure 5 As shown, in this embodiment, a vertical plate 17 is fixedly installed on one side of the fixed block 81, and a round rod 18 is movably inserted through the center of the vertical plate 17. The round rod 18 and the rotating rod 12 are driven by a bevel gear 19. A movable gear 20 is fixedly sleeved on the other end of the round rod 18. A fixed rack 21 is fixedly installed on the fixed plate 7. The fixed rack 21 movably inserts through the fixed block 81 and is driven by the movable gear 20.

[0032] Specifically, when the sliding block 10 moves synchronously with the fixed block 81, the moving gear 20 meshes with the fixed rack 21. The rotation of the moving gear 20 will drive the round rod 18 to rotate. Through the transmission of the bevel gear 19, the rotating rod 12 will rotate. The rotation of the rotating rod 12 can ultimately realize the reciprocating swing of the swing plate 11. The vertical plate 17 provides support for the round rod 18.

[0033] See Figures 5-7 As shown, in this embodiment, a positioning block 22 is fixedly provided on one side of the fixed block 81, and a moving rod 23 is movably provided through the positioning block 22. A moving ring 24 is fixedly provided at one end of the moving rod 23, and the moving ring 24 movably abuts against the positioning ring 15.

[0034] Specifically, the tilt angle of the rotating ring 13 determines the distance the drive rack 83 reciprocates, and the reciprocating distance of the drive gear determines the reciprocating swing amplitude of the incomplete gear 9 and the swing plate 11. Initially, the swing plate 11 is located near the center of the ring groove 201 and the rotating shaft 1. Subsequently, the swing plate 11 moves towards the heat dissipation hole 202 along with the sliding block 10, carrying some heat to the vicinity of the heat dissipation hole 202. It takes a certain amount of time for the heat dissipation hole 202 to dissipate heat because the temperature near the heat dissipation hole 202 is higher than the temperature at the center of the ring groove 201. Therefore, when the swing plate 11 reaches the vicinity of the heat dissipation hole 202, the swing amplitude can be appropriately increased to further promote heat dissipation. When the sliding block 10 approaches the vicinity of the heat dissipation hole 202, the moving rod 23 moves away from the rotating ring 13, moving... The movement of rod 23 will cause the moving ring 24 to move, and the moving ring 24 will cause the positioning ring 15 to move away from the rotating rod 12 and away from the rotating ring 13. The connecting plate 16 will rotate, so that the rotating ring 13 tilts at a larger angle. Thus, the rotation of the rotating rod 12 will cause the rotating ring 13 to swing more, so the drive rack 83 will move laterally and reciprocate a greater distance, and the swing plate 11 will swing more. The positioning block 22 provides support for the moving rod 23. Similarly, when the sliding block 10 moves away from the heat dissipation hole 202 and returns to the initial position, the moving rod 23 moves in the opposite direction to the initial position, and the swing amplitude of the swing plate 11 is also adjusted back to the initial level. Because the temperature in the middle of the ring groove 201 is lower and the heat density is lower, an excessive swing amplitude may lead to energy waste. A smaller swing amplitude can reduce excessive disturbance to the hot air and avoid affecting the cooling effect of other areas.

[0035] See Figures 5-7 As shown, in this embodiment, a positioning plate 25 is fixedly sleeved on the outside of the moving rod 23, and a lead screw 26 is movably and through the positioning block 22 located below the moving rod 23. A sleeve 27 is movably sleeved on the outside of the lead screw 26, and the sleeve 27 is fixedly connected to the positioning plate 25.

[0036] Specifically, when the sliding block 10 and the swing plate 11 are near the heat dissipation hole 202, rotating the lead screw 26 will drive the sleeve 27, positioning plate 25, moving rod 23, moving ring 24, and positioning ring 15 to move away from the rotating ring 13. The tilt angle of the rotating ring 13 increases, the moving distance of the drive rack 83 increases, and the swing amplitude of the swing plate 11 increases, which can further improve the heat dissipation effect.

[0037] See Figures 4-5 and Figure 7 As shown, in this embodiment, a cylinder 28 is fixedly provided at the end of the lead screw 26 away from the sleeve 27. An arc groove 281 is provided on the cylinder 28. A limit rod 29 is fixedly provided on one side of the fixing plate 7. The limit rod 29 slides and fits against the arc groove 281.

[0038] Specifically, when the sliding block 10 and the fixed block 81 move together toward the heat dissipation hole 202, the limiting rod 29 will contact the arc groove 281 of the cylinder 28, thereby causing the cylinder 28 to rotate. The rotation of the cylinder 28 will cause the lead screw 26 to rotate, which can increase the tilt angle of the rotating ring 13, thus increasing the swing amplitude of the swing plate 11. Similarly, when the sliding block 10 and the fixed block 81 move in the opposite direction, the limiting action of the limiting rod 29 will cause the cylinder 28 and the lead screw 26 to rotate in the opposite direction, thus restoring the rotating ring 13 to its initial state.

[0039] See Figure 8 As shown, in this embodiment, the swing plate 11 has multiple through holes 111 that are movably opened through it.

[0040] Specifically, the swing plate 11 has multiple through holes 111 that allow air to pass directly through the swing plate 11, forming local turbulence and accelerating heat transfer.

[0041] See Figure 8 and Figure 9 As shown, in this embodiment, the swing plate 11 has a slot 112, and a movable plate 30 is movably disposed in the slot 112. The movable plate 30 has a number of circular holes 301 that are the same as the number of through holes 111.

[0042] Specifically, when the swing plate 11 begins to move towards the heat dissipation hole 202, the circular hole 301 of the movable plate 30 is not aligned with the through hole 111 of the swing plate 11. During the swing, the swing plate 11 can push more hot air to the vicinity of the heat dissipation hole 202 because the hot air cannot pass through the through hole 111, which is in a closed state. When the swing plate 11 approaches the heat dissipation hole 202, the movable plate 30 is pulled outward along the slot 112, so that the circular hole 301 on the movable plate 30 is aligned with the through hole 111 of the swing plate 11. When the swing plate 11 swings, air can pass through the swing plate 11, forming local turbulence and accelerating heat transfer.

[0043] See Figures 8-10 As shown, in this embodiment, a fixed rod 31 is movably disposed inside the swing plate 11. The two ends of the fixed rod 31 are fixedly connected to the sliding block 10. A ring 32 is fixedly sleeved on the outside of the fixed rod 31. A circular groove 321 and an inclined groove 322 are provided on the ring 32, and the two are connected to each other. A guide rod 33 is fixedly disposed on one side of the movable plate 30. The end of the guide rod 33 away from the movable plate 30 is slidably connected to the circular groove 321 and the inclined groove 322.

[0044] Specifically, when the swing plate 11 begins to move toward the heat dissipation hole 202, the swing plate 11 rotates relative to the fixed rod 31 with a small swing amplitude. During the rotation of the swing plate 11, it will drive the movable plate 30 to rotate synchronously. One end of the guide rod 33 moves back and forth along the circular groove 321 opened in the ring 32. When the swing plate 11 is about to approach the heat dissipation hole 202, the swing amplitude of the swing plate 11 increases. After the guide rod 33 rotates along the circular groove 321, it will enter the inclined groove 322, thereby driving the guide rod 33 and the movable plate 30 to move laterally. The movable plate 30 moves in the slot 112 so that the through hole 111 is aligned with the circular hole 301. During the swing of the swing plate 11, air will pass through the through hole 111, forming local turbulence, accelerating heat transfer and promoting heat dissipation.

[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The above-described embodiments are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
