Abstract
Description
Technical Field
[0001] This utility model relates to the field of rubber product raw material mixing technology, and more specifically, it relates to a raw material mixing device for rubber product production. Background Technology
[0002] In the field of rubber product manufacturing, the uniformity of raw material mixing, equipment safety, and structural stability are key factors affecting product quality. However, the raw material mixing devices used in rubber product manufacturing currently on the market still have many technical defects in practical applications. These problems not only affect production efficiency but may also lead to equipment damage and a decline in product quality.
[0003] The primary problem is the severe lack of mixing efficiency. Existing mixing methods have significant drawbacks: First, the single-axis mixing structure leads to low stirring efficiency; second, stable vortices are easily formed inside the tank during the mixing process; and third, these vortices cause some materials to remain in a relatively static state. These shortcomings of traditional mixing methods not only limit mixing efficiency but may also lead to unstable product quality due to uneven mixing, affecting the performance of the final product.
[0004] More notably, the safety protection mechanism has significant flaws. Existing technologies generally lack effective overload protection devices, which presents significant problems: First, the mixing shaft is prone to breakage when the mixing plate encounters large resistance, and the motor may be damaged under overload conditions; second, there is a lack of function to adjust the overload triggering mechanism according to different processing requirements. This design deficiency not only increases the risk of equipment damage, but may also lead to production interruption due to equipment failure, affecting the production schedule.
[0005] Most critically, the structural stability is seriously insufficient. Although some equipment has achieved adjustable overload protection through design improvements, this design still has obvious defects: First, the simple structural design is difficult to adapt to the high-speed operating environment. The adjusted structure is prone to loosening due to high-speed rotation, and the sensitivity of the triggering mechanism is prone to deviation. This structural design deficiency not only affects the reliability of the protection mechanism, but may also lead to false protection or insufficient protection due to the inaccuracy of the triggering mechanism.

[0031] Please see Figures 1-5A raw material mixing device for rubber product manufacturing includes a mixing tank 1, a mixing device installed inside the mixing tank 1, a detachable tank cover 2 on top of the mixing tank 1, and a protective device on top of the tank cover 2. The protective device includes a coupling sleeve 3, a coupling rod 4, a control sleeve 5, a coupling groove 6, a linkage frame 7, an adjusting groove 8, an adjusting sleeve 9, an adjusting block 10, a push spring 11, and a support block 12. The coupling sleeve 3 is detachably fitted onto the outside of the coupling rod 4. The control sleeve 5 is rotatably installed on the outside of the coupling sleeve 3. The coupling groove 6 is opened on the outside of the coupling rod 4. One end of the linkage frame 7 is inserted into the coupling groove 6. The adjusting groove 8 is opened in the coupling sleeve 3. The outer wall of the adjusting sleeve 9 is movably connected to the inner wall of the control sleeve 5 by threads. The adjusting block 10 is movably disposed in the adjusting groove 8. The push spring 11 has two ends. The coupling sleeve 3 is connected to the adjusting block 10 and the support block 12 respectively. A reinforcing mechanism is provided on the outside of the coupling sleeve 3. The reinforcing mechanism includes a reset plate 13, a reset groove 14, a reset hole 15, a locking sleeve 16, a support rod 17, a reinforcing rod 18, a reset block 19, a reset spring 20, and a fixing block 21. The reset plate 13 is rotatably installed on the outside of the coupling sleeve 3. The reset groove 14 is opened on the reset plate 13. The reset hole 15 is opened at one end of the reset groove 14. The locking sleeve 16 is sleeved on the outside of the coupling sleeve 3. The support rod 17 is fixedly connected to one side of the locking sleeve 16. The reinforcing rod 18 is connected to the top of the support rod 17. The reset block 19 is fixedly connected to one side of the reset plate 13. The fixing block 21 is fixedly installed on the outside of the coupling sleeve 3. The two ends of the reset spring 20 are connected to the reset block 19 and the fixing block 21 respectively.
[0032] The mixing device includes a mounting frame 22, a motor 23, a mixing shaft 24, a mixing plate 25, and a baffle plate 26. The mounting frame 22 is detachably mounted on the tank cover 2. The motor 23 is detachably mounted above the mounting frame 22. The output end of the motor 23 passes through the mounting frame 22 and is connected to the top of the coupling sleeve 3. The top of the mixing shaft 24 is connected to the bottom of the coupling rod 4. Multiple mixing plates 25 are mounted on the outside of the mixing shaft 24. Multiple baffle plates 26 are detachably mounted on the inner wall of the mixing tank 1.
[0033] Multiple feed pipes 27 are fixedly provided on the lid 2, and a discharge pipe 28 is connected to the bottom of the mixing tank 1.
[0034] In this embodiment, when the equipment is needed, the triggering mechanism of the protective device is first adjusted according to the processing requirements. Then, the raw material is added into the mixing tank 1 through the feed pipe 27. Next, the motor 23 mounted on the mounting frame 22 is turned on. The motor 23 drives the coupling sleeve 3 connected to the output end to rotate. Then, the coupling sleeve 3, through the adjusting groove 8, drives the linkage frame 7 and the coupling groove 6 to rotate the coupling rod 4, thereby driving the mixing shaft 24 to rotate. The mixing shaft 24 then drives the multiple mixing plates 25 mounted on the outside to rotate, achieving agitation and mixing of the raw materials. Due to the setting of multiple baffle plates 26, the raw material is subjected to resistance while rotating with the mixing plates 25, thus avoiding the formation of stable vortices in the mixing tank 1, thereby ensuring uniform mixing of the raw materials and improving efficiency. The mixing efficiency is improved. After mixing, the finished product can be transported to the next process through the conveying equipment connected to the discharge pipe 28. When the mixing plate 25 encounters greater resistance, it will transmit the reaction force to the mixing shaft 24 and then to the coupling rod 4, so that the coupling rod 4 drives the coupling groove 6 to stop rotating. Then, the inner wall of the coupling groove 6 presses against the end of the linkage frame 7. Due to the rounded corner design of the end of the linkage frame 7 and the inner wall of the coupling groove 6, the end of the linkage frame 7 slides out of the coupling groove 6. Then, the other end of the linkage frame 7 presses down the support block 12, so that the support block 12 slides down along the adjusting groove 8 and cooperates with the adjusting block 10 to press against the push spring 11, thereby causing the motor 23 to drive the coupling sleeve 3 to run idle, preventing the motor 23 from being overloaded and damaged, and preventing the mixing shaft 24 from breaking.
[0035] Please see Figures 3-5 As a further implementation of the overall equipment: the side wall of the coupling sleeve 3 is provided with multiple moving grooves 29, and the moving block 30 is slidably provided in the moving groove 29. The inner wall of the adjusting sleeve 9 is fixedly connected to the adjusting block 10 through the moving block 30.
[0036] Multiple locking rods 31 are slidably provided on the side wall of the control sleeve 5, and multiple locking grooves 32 are provided on the outer side of the coupling sleeve 3, with one end of the locking rod 31 inserted into the locking groove 32.
[0037] A connecting spring 33 is provided on the outside of the control sleeve 5, and the other end of the locking rod 31 is connected to the outer wall of the control sleeve 5 through the connecting spring 33.
[0038] Multiple guide grooves 34 are provided on the outer side of the coupling sleeve 3, and multiple guide blocks 35 are fixedly provided on the inner wall of the clamping sleeve 16. The guide blocks 35 are slidably disposed in the guide grooves 34.
[0039] A support spring 36 is connected to one side of the retaining sleeve 16, and a thrust bearing 37 is detachably provided on one side of the reset plate 13. The top of the support spring 36 is connected to the thrust bearing 37.
[0040] More specifically, when the triggering mechanism of the protective device needs to be adjusted according to requirements, the reset plate 13 is first rotated forward, causing the reset block 19 on one side to rotate forward. Then, the reset block 19 and the fixing block 21 cooperate to press the reset spring 20. At the same time, the reset plate 13 will drive the reset groove 14 and the reset hole 15 to rotate, and the reset plate 13 will drive the thrust bearing 37 installed on one side to rotate. When the reset spring 20 is pressed to its limit, the reset hole 15 will just rotate to a position concentric with the support rod 17 and the reinforcing rod 18. Then, the locking sleeve 16 is pushed, causing the locking sleeve 16 to drive the guide block 35 to slide along the guide groove 34. The locking sleeve 16 will drive the reinforcing rod 18 to gradually penetrate into the reset hole 15 through the support rod 17. At the same time, the locking sleeve 16 will... The thrust bearing 37 cooperates with the support spring 36 to compress it. When the support spring 36 is compressed to its limit, the reinforcing rod 18 just passes through the reset hole 15 and moves to the other side of the reset plate 13. Then the reset plate 13 is released, and the reset spring 20 pushes the reset block 19 to rotate in the opposite direction. Then the reset block 19 will drive the reset hole 15 and the reset groove 14 to rotate in the opposite direction through the reset plate 13, so that the support rod 17 slides into the reset groove 14. Then the support rod 17 and the reinforcing rod 18 cooperate to limit the locking sleeve 16 to one side of the reset plate 13. Then the locking sleeve 16 no longer limits the locking rod 31. Then the control sleeve 5 is rotated in the forward direction, so that the control sleeve 5 drives the multiple locking rods 31 that are slidably set on the side wall to rotate. Then the inside of the locking groove 32 compresses one end of the locking rod 31. The rounded corners at the inner edge of the locking groove 32 and the end of the locking rod 31 allow one end of the locking rod 31 to slide out of the locking groove 32, while the other end of the locking rod 31 stretches the connecting spring 33. Simultaneously, due to the threaded connection between the inner wall of the control sleeve 5 and the adjusting sleeve 9, and the limiting effect of the moving block 30 and the moving groove 29 on the adjusting sleeve 9, the adjusting sleeve 9 cannot rotate. The adjusting sleeve 9 then causes the moving block 30 to slide along the moving groove 29, and the moving block 30 causes the adjusting block 10 to slide upwards in the adjusting groove 8. This reduces the distance between the adjusting block 10 and the support block 12, compressing the length of the push spring 11 and increasing the force exerted by the push spring 11 on the support block 12, making the protective device less likely to be triggered. Once properly adjusted, the rotation stops. The control sleeve 5 is moved, causing the connecting spring 33 to slide the locking rod 31 into the corresponding locking groove 32. Then, the reset plate 13 is rotated forward again, causing the reset plate 13 to drive the reset block 19 to rotate again. Then, the reset block 19 and the fixing block 21 cooperate to press the reset spring 20, and the reset plate 13 drives the reset hole 15 and the reset groove 14 to rotate forward again. When the reset hole 15 rotates to the position concentric with the reinforcing rod 18, the support spring 36 pushes the locking sleeve 16 to slide and reset. The locking sleeve 16 will drive the guide block 35 to slide and reset along the guide groove 34. Then, the locking sleeve 16 drives the reinforcing rod 18 to slide and reset through the support rod 17. When the support spring 36 is fully reset, the reset plate 13 is released, and the reset spring 20 pushes the reset block 19 to reset.Then, the reset block 19, through the reset plate 13, drives the reset hole 15 and reset groove 14 to rotate and reset to a position that does not correspond to the reinforcing rod 18 and support rod 17. The reinforcing rod 18 and support rod 17 then cooperate to limit the locking sleeve 16 to one side of the reset plate 13. Combined with the guide block 35 and guide groove 34 limiting the locking sleeve 16, the locking sleeve 16 cannot move. Then, the inner wall of the locking sleeve 16 limits the outer end of the locking rod 31, causing the locking rod 31 to cooperate with the locking groove 32 to lock the control sleeve 5, thereby ensuring structural stability and ensuring stable equipment operation.
[0041] In summary, when using or operating the equipment: First, adjust the triggering mechanism of the protective device according to the processing requirements. Then, add the raw material into the mixing tank 1 through the feed pipe 27. Next, turn on the motor 23 installed on the mounting frame 22. The motor 23 drives the coupling sleeve 3 connected to the output end to rotate. Then, the coupling sleeve 3 drives the linkage frame 7 and the coupling groove 6 to rotate through the adjustment groove 8, thereby driving the coupling rod 4 to rotate, which in turn drives the mixing shaft 24 to rotate. The mixing shaft 24 then drives the multiple mixing plates 25 installed on the outside to rotate, realizing the agitation and mixing of the raw materials. Due to the setting of multiple baffles 26, the raw materials are resisted while rotating with the mixing plates 25, thereby avoiding the formation of stable vortices in the mixing tank 1, thus ensuring the uniform mixing of the raw materials. The mixing process is efficient and improves mixing efficiency. After mixing, the finished product is conveyed to the next process through the conveying equipment connected to the discharge pipe 28. When the mixing plate 25 encounters greater resistance, it will transmit the reaction force to the mixing shaft 24 and then to the coupling rod 4, causing the coupling rod 4 to stop rotating the coupling groove 6. Then, the inner wall of the coupling groove 6 presses against the end of the linkage frame 7. Due to the rounded corner design of the end of the linkage frame 7 and the inner wall of the coupling groove 6, the end of the linkage frame 7 slides out of the coupling groove 6. Then, the other end of the linkage frame 7 presses down the support block 12, causing the support block 12 to slide down along the adjusting groove 8 and cooperate with the adjusting block 10 to press against the push spring 11, thereby causing the motor 23 to drive the coupling sleeve 3 to run idle, preventing the motor 23 from being overloaded and damaged, and preventing the mixing shaft 24 from breaking.
[0042] When the triggering mechanism of the protective device needs to be adjusted according to requirements, firstly, rotate the reset plate 13 in the forward direction, causing the reset block 19 on one side to rotate in the forward direction. Then, the reset block 19 and the fixing block 21 cooperate to squeeze the reset spring 20. At the same time, the reset plate 13 will drive the reset groove 14 and the reset hole 15 to rotate, and the reset plate 13 will drive the thrust bearing 37 installed on one side to rotate. When the reset spring 20 is squeezed to the limit, the reset hole 15 will just rotate to a position concentric with the support rod 17 and the reinforcing rod 18. Then, push the locking sleeve 16, causing the locking sleeve 16 to drive the guide block 35 to slide along the guide groove 34. The locking sleeve 16 will drive the reinforcing rod 18 to gradually pass into the reset hole 15 through the support rod 17. At the same time, the locking sleeve 16 and the thrust shaft will... The support spring 36 is compressed by the bearing 37. When the support spring 36 is compressed to its limit, the reinforcing rod 18 just passes through the reset hole 15 and moves to the other side of the reset plate 13. Then the reset plate 13 is released, and the reset spring 20 pushes the reset block 19 to rotate in the opposite direction. Then the reset block 19 will drive the reset hole 15 and the reset groove 14 to rotate in the opposite direction through the reset plate 13, so that the support rod 17 slides into the reset groove 14. Then the support rod 17 and the reinforcing rod 18 cooperate to limit the locking sleeve 16 to one side of the reset plate 13. Then the locking sleeve 16 no longer limits the locking rod 31. Then the control sleeve 5 is rotated in the forward direction, so that the control sleeve 5 drives the multiple locking rods 31 sliding on the side wall to rotate. Then the inside of the locking groove 32 compresses one end of the locking rod 31. The rounded corners at the inner edge of the 32 and the end of the locking rod 31 allow one end of the locking rod 31 to slide out of the locking groove 32, while the other end of the locking rod 31 stretches the connecting spring 33. Simultaneously, due to the threaded connection between the inner wall of the control sleeve 5 and the adjusting sleeve 9, and the limiting effect of the moving block 30 and the moving groove 29 on the adjusting sleeve 9, the adjusting sleeve 9 cannot rotate. The adjusting sleeve 9 then causes the moving block 30 to slide along the moving groove 29, which in turn causes the adjusting block 10 to slide upwards in the adjusting groove 8. This reduces the distance between the adjusting block 10 and the support block 12, compressing the length of the push spring 11 and increasing the force exerted by the push spring 11 on the support block 12, making the protective device less likely to be triggered. Once properly adjusted, rotation stops. The control sleeve 5 is operated, causing the connecting spring 33 to slide the locking rod 31 into the corresponding locking groove 32. Then, the reset plate 13 is rotated forward again, causing the reset plate 13 to drive the reset block 19 to rotate again. Then, the reset block 19 and the fixing block 21 cooperate to press the reset spring 20, and the reset plate 13 drives the reset hole 15 and the reset groove 14 to rotate forward again. When the reset hole 15 rotates to the position concentric with the reinforcing rod 18, the support spring 36 pushes the locking sleeve 16 to slide and reset. The locking sleeve 16 will drive the guide block 35 to slide and reset along the guide groove 34. Then, the locking sleeve 16 drives the reinforcing rod 18 to slide and reset through the support rod 17. When the support spring 36 is fully reset, the reset plate 13 is released, and the reset spring 20 pushes the reset block 19 to reset.Then, the reset block 19, through the reset plate 13, drives the reset hole 15 and reset groove 14 to rotate and reset to a position that does not correspond to the reinforcing rod 18 and support rod 17. The reinforcing rod 18 and support rod 17 then cooperate to limit the locking sleeve 16 to one side of the reset plate 13. Combined with the guide block 35 and guide groove 34 limiting the locking sleeve 16, the locking sleeve 16 cannot move. Then, the inner wall of the locking sleeve 16 limits the outer end of the locking rod 31, causing the locking rod 31 to cooperate with the locking groove 32 to lock the control sleeve 5, thereby ensuring structural stability and ensuring stable equipment operation.
