Description

Technical Field

[0001] The present invention relates to the technical field of polyurethane rubber, and more specifically, to a synthesis process for producing polyurethane rubber. Background Art

[0002] As a high-performance material, polyurethane rubber has a wide range of applications in many industrial fields, including automotive, aerospace, machinery manufacturing, construction, and footwear, due to its excellent physical and chemical properties, such as high elasticity, abrasion resistance, oil resistance, and chemical corrosion resistance.

[0003] The traditional synthesis process of polyurethane rubber generally follows the following process: First, solid raw materials such as polyester polyol and isocyanate need to be melted separately through independent equipment, and then the melted raw materials are transferred to a reaction kettle for the synthesis of prepolymers. During this process, precise temperature, time, and environmental conditions control are required for each link to ensure the quality of the raw material melting process and the smooth progress of the prepolymer synthesis reaction.

[0004] However, this traditional process has many deficiencies. On the one hand, melting polyester polyol and isocyanate separately not only involves cumbersome operation steps but also requires the use of multiple independent equipment, which leads to the scattered layout of the equipment, increasing the equipment cost and the floor area of the workshop. The operation processes and parameter settings of different equipment significantly increase the operational complexity during the production process. Operators need to switch operations between different equipment, which is prone to operation errors, such as inaccurate temperature control of different equipment and improper melting time control. These factors will have a negative impact on the quality of the raw materials. Moreover, due to the differences in the influence of equipment performance, environmental factors, and human operations on different batches of raw materials during separate melting, it is difficult to ensure the consistency of the states of different batches of raw materials when they enter the reaction kettle, resulting in large fluctuations in the quality of the final product and difficulty in ensuring the consistency and repeatability of the product.

[0005] On the other hand, during the separate melting process, the raw materials need to be transferred between different equipment. During this period, the materials will be more exposed to the external environment, increasing the risk of introducing impurities. These impurities may come from the air, the surface of the equipment, or the contact objects during the material transfer process. Once mixed into the raw materials, they will interfere with the prepolymer synthesis reaction, affecting the purity and quality of the polyurethane rubber product, and further affecting the performance and reliability of the product.

[0006] In addition, from the perspective of energy utilization, using multiple devices to melt raw materials separately requires providing energy for each device individually, resulting in the decentralized use of energy, a relatively low overall energy utilization rate, and an increase in production costs. Especially during large-scale production, this high-energy consumption problem becomes more prominent. In view of this, we propose a synthetic process for producing polyurethane rubber.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. By improving the existing synthesis device for producing polyurethane rubber, a blower, a heating mechanism, a transmission shell group and a synthesis mechanism are arranged on the frame. The driving and adjusting mechanism drives the main rotating component, the driven rotating component, the fixing component, the switching component and the movable component to form a revolution state, so that the heating mechanism evenly melts the solid polyester polyol placed in the reaction tank group, and then by adding solid isocyanate, the solid isocyanate is evenly melted and fused with the polyester polyol. Finally, the state of the movable component is adjusted by the driving and adjusting mechanism to realize that the movable component forms a mixing state, effectively reducing the transfer of materials between different devices and the start-up and debugging time of the devices. From the time when the solid polyester polyol is put in to the completion of the fusion with isocyanate, it can be efficiently completed in a coherent system, greatly shortening the production cycle. Compared with the traditional batch production, the production efficiency can be further improved to meet the market demand for polyurethane rubber.

[0023] 2. In the present invention, the driving and adjusting mechanism drives the main shaft, the main turntable and the external tooth groove to rotate. When the driving and adjusting mechanism is in the full rotation connection state, the main turntable drives the adjusting component to rotate. Since the adjusting component is inserted into the through hole of the bottom turntable, the bottom turntable is driven to rotate synchronously. The main turntable also drives the fixing component, the switching component and the movable component at its top to rotate together, so that the materials in the movable component rotate in the reaction tank group, realizing uniform heating and melting. Compared with the traditional static heating method, the rotary heating method can make the materials be heated and melted more uniformly, reduce local overheating or overcooling phenomena, avoid changes in the properties of raw materials caused by uneven heating, thereby improving the product quality. At the same time, it also speeds up the melting speed and saves production time.

[0024] 3. In the present invention, when the driving and adjusting mechanism is in the adjusting connection state, the driving and adjusting mechanism drives the main shaft, the main turntable and the external tooth groove to rotate. The external tooth groove meshes with the driven gear to drive the driven gear to rotate. Since the adjusting component is in a fixed state, the bottom turntable and the internal tooth groove are both in a fixed state, and the driven gear rotates in a circular motion around the circular chute on the bottom turntable. The driven gear drives the stop bar to rotate in a circle. When the stop bar contacts the switching component, it pushes the switching component to rotate on the fixing component, realizing the switching of the form of the movable component to the unfolded state. At this time, the driving and adjusting mechanism is adjusted to the full rotation connection state again, so that the unfolded movable component rotates, not only throwing off some of the raw materials adhered to the movable component, but also enabling the melted polyester polyol and isocyanate to be fully fused through the rotation of the movable component, avoiding waste of raw material residues. Compared with the traditional mixing method, it greatly improves the uniformity and sufficiency of material mixing, provides a better reaction basis for the synthesis of polyurethane rubber, helps to improve the physical properties and chemical stability of the product, and enhances the market competitiveness of the product.

[0025] 4. In the present invention, when the stop bar contacts the push rod of the switching component, the stop bar pushes the push rod to rotate. The push rod drives the switching disk to rotate on the inner wall of the fixing ring. The switching disk drives the straight chute to rotate. The straight chute rotates and squeezes the sliding block slidably connected therein to slide. The sliding block drives the movable block, the sliding rod and the arc plate to move. Since the sliding rod is movably inserted into the long hole of the fixing ring, due to the limitation of the long hole, the sliding block generates an offset. Multiple sliding blocks and arc plates realize the unfolded state. After both materials are melted and fused, at this time, the driving and adjusting mechanism is adjusted to the full rotation connection state again, so that the arc plate in the unfolded state rotates, not only throwing off some of the raw materials adhered to the arc plate, but also enabling the melted polyester polyol and isocyanate to be fully fused through the rotation of the arc plate, avoiding waste of raw material residues. And it not only helps to improve the material mixing effect, but also plays a role in cleaning the equipment, reducing the residual accumulation of raw materials inside the equipment, reducing the risks of equipment blockage and corrosion caused by material residues, facilitating the daily cleaning and maintenance of the equipment, helping to extend the service life of the equipment, reducing the equipment maintenance cost, and ensuring the continuity and stability of the production process.

[0026] 5. In the present invention, the electric push rod is driven to drive the insertion rod to move, the insertion rod drives the fixed collar to move, the fixed collar drives the two movable sleeve blocks, the two connecting rods and the two slots to move until the slot at the top is inserted and fixed on the fixed insertion block B fixedly connected to the bottom end of the main turntable or until the slot at the bottom is inserted and fixed on the fixed insertion block A fixedly connected to the mounting plate; when the slot is inserted and fixed with the fixed insertion block B, the driving and adjusting mechanism is in the integral rotation connection state; when the slot is inserted and fixed with the fixed insertion block A, the driving and adjusting mechanism is in the adjusting connection state; the two states respectively adapt to the melting and mixing stages of the material. In the melting stage, the integral rotation connection state can ensure that the material is evenly heated and melted in the reaction tank group, improving the melting efficiency and quality. In the mixing stage, the adjusting connection state promotes the material to be mixed in a specific manner, ensuring the sufficiency and uniformity of the mixing. This design of flexibly switching to adapt to the requirements of different production stages optimizes the production process, helps to improve the product quality and production efficiency, and at the same time reduces the operation difficulty of the equipment.

[0050] To facilitate the understanding of the technical solution of the present invention by those skilled in the art, the technical solution of the present invention will be further described below with reference to the accompanying drawings of the specification.

[0051] Example 1

[0052] As Figures 2 to 12As shown in the figure, the present invention provides a synthesis device, including a frame 1, a fan 2 is provided at one end of the frame 1, a heating mechanism 3 is provided near the fan 2 on the frame 1, a transmission shell group 4 is provided at one end of the heating mechanism 3 away from the fan 2, a synthesis mechanism 5 is provided at one end of the transmission shell group 4 away from the heating mechanism 3, and a driving and adjusting mechanism 6 is provided at the bottom end of the frame 1 where the synthesis mechanism 5 is located;

[0053] The synthesis mechanism 5 includes a reaction tank group 501, a main rotation component 502, a secondary rotation component 503, a fixing component 504, a switching component 505 and a moving component 506. The reaction tank group 501 is provided on the frame 1 and one end is connected to the transmission shell group 4. The main rotation component 502 is provided at the bottom end of the reaction tank group 501. The secondary rotation component 503 is movably provided on the main rotation component 502. The fixing component 504 is fixedly connected to the main rotation component 502. The switching component 505 is rotatably provided on the fixing component 504. One end of the moving component 506 is movably connected to the switching component 505, and the other end of the moving component 506 is movably connected to the fixing component 504.

[0054] The present invention improves the existing synthesis device for polyurethane rubber production. By setting a fan 2, a heating mechanism 3, a transmission shell group 4 and a synthesis mechanism 5 on the frame 1, and driving the main rotation component 502, the secondary rotation component 503, the fixing component 504, the switching component 505 and the moving component 506 to form a revolution state through the driving and adjusting mechanism 6, the heating mechanism 3 uniformly melts the solid polyester polyol placed in the reaction tank group 501, and then by adding solid isocyanate, the solid isocyanate is uniformly melted and fused with the polyester polyol. Finally, by adjusting the state of the moving component 506 through the driving and adjusting mechanism 6 to form a mixing state of the moving component 506, it effectively reduces the transfer of materials between different devices and the start-up and debugging time of the devices. From the time when the solid polyester polyol is put in to the completion of the fusion with isocyanate, it can be efficiently completed in a coherent system, greatly shortening the production cycle. Compared with the traditional batch production, the production efficiency can be further improved to meet the market demand for polyurethane rubber.

[0055] In the embodiment of the present invention, the reaction tank group 501 includes a reaction tank 5011, a feeding port 5012, a discharging port 5013 and a mounting plate 5014. The reaction tank 5011 is provided on the frame 1 and one end is connected to the transmission shell group 4. The feeding port 5012 is opened at the top end of the reaction tank 5011. The discharging port 5013 is opened at the bottom end of the reaction tank 5011. The mounting plate 5014 is connected to the bottom end of the reaction tank 5011. One end of the moving component 506 away from the fixing component 504 is movably connected to the inner top wall of the reaction tank 5011. One end of the driving and adjusting mechanism 6 is connected to the mounting plate 5014, and the other end of the driving and adjusting mechanism 6 is connected to the main rotation component 502.

[0056] In the present invention, first, solid polyester polyol raw materials are put into the feeding port 5012, so that the solid polyester polyol falls into the movable assembly 506. After the solid polyester polyol is uniformly melted and filtered through the movable assembly 506, solid isocyanate raw materials are added through the feeding port 5012. Then, the driving and adjusting mechanism 6 drives the main rotating assembly 502, the secondary rotating assembly 503, the fixed assembly 504, the switching assembly 505 and the movable assembly 506 to form a revolution state, so that the heating mechanism 3 uniformly melts the solid isocyanate placed in the reaction tank group 501. During this melting process, the isocyanate is gradually decomposed and fused with the polyester polyol, realizing the premature synthesis of partial prepolymer. In the front-end treatment, not only the operation steps are reduced, but also the treatment time is shortened, further improving the synthesis efficiency of polyurethane rubber.

[0057] As another embodiment of the present invention, the main rotating assembly 502 includes a main shaft 5021, a main turntable 5022, an external tooth groove 5023, a bottom turntable 5024, an internal tooth groove 5025, a middle hole 5026 and a through hole 5027. The main shaft 5021 is connected to the driving and adjusting mechanism 6, the main turntable 5022 is connected to the main shaft 5021, the external tooth groove 5023 is opened on the main turntable 5022, the bottom turntable 5024 is rotatably arranged at the bottom end of the reaction tank group 501, the internal tooth groove 5025 is opened on the inner wall of the bottom turntable 5024, the middle hole 5026 is opened at the center of the bottom turntable 5024, and the through holes 5027 are symmetrically opened on the bottom turntable 5024. One end of the secondary rotating assembly 503 is engaged with the external tooth groove 5023, and the other end of the secondary rotating assembly 503 is engaged with the internal tooth groove 5025. In the present invention, by driving the driving and adjusting mechanism 6 to drive the main shaft 5021, the main turntable 5022 and the external tooth groove 5023 to rotate, when the driving and adjusting mechanism 6 is in a full-rotation connection state, the main turntable 5022 drives the adjusting assembly 604 to rotate. Since the adjusting assembly 604 is inserted into the through hole 5027 of the bottom turntable 5024, the bottom turntable 5024 is driven to rotate synchronously. The main turntable 5022 also drives the fixed assembly 504, the switching assembly 505 and the movable assembly 506 at its top end to rotate together, so that the materials in the movable assembly 506 rotate in the reaction tank group 501, realizing uniform heating and melting. Compared with the traditional static heating method, the rotating heating method can make the materials be heated and melted more uniformly, reduce local overheating or overcooling phenomena, avoid changes in the raw material properties caused by uneven heating, thereby improving the product quality. At the same time, it also speeds up the melting speed and saves production time.

[0058] In the embodiment of the present invention, a circular sliding groove 5028 is also opened on the bottom turntable 5024, and the secondary rotating assembly 503 is slidably arranged on the circular sliding groove 5028;

[0059] The slave rotating assembly 503 includes a driven gear 5031 and a shift lever 5032. The bottom end of the driven gear 5031 is slidably disposed on the circular chute 5028.

The shift lever 5032 is fixedly disposed at the top end of the driven gear 5031.

[0060] In the present invention, when the driving and adjusting mechanism 6 is in the adjusted connection state, the driving and adjusting mechanism 6 is driven to drive the main shaft 5021, the main turntable 5022 and the external tooth groove 5023 to rotate. The external tooth groove 5023 is meshed with the driven gear 5031 to drive the driven gear 5031 to rotate. Since the adjusting assembly 604 is in a fixed state, the bottom turntable 5024 and the internal tooth groove 5025 are both in a fixed state, and the driven gear 5031 rotates in a circular motion around the circular chute 5028 on the bottom turntable 5024. The driven gear 5031 drives the shift lever 5032 to rotate. When the shift lever 5032 contacts the switching assembly 505, the switching assembly 505 is pushed to rotate on the fixing assembly 504, realizing the switching of the form of the movable assembly 506, as Figure 12 shown, in the unfolded state. At this time, the driving and adjusting mechanism 6 is adjusted to the full rotation connection state, so that the unfolded movable assembly 506 rotates, not only throwing off some of the raw materials adhered to the movable assembly 506, but also enabling the fully melted polyester polyol and isocyanate to be fully mixed through the rotation of the movable assembly 506, avoiding waste of raw material residues. Compared with the traditional mixing method, the uniformity and sufficiency of material mixing are greatly improved, providing a better reaction basis for the synthesis of polyurethane rubber, helping to improve the physical properties and chemical stability of the product, and enhancing the market competitiveness of the product;

[0061] As another embodiment of the present invention, the fixing assembly 504 includes a fixing ring 5041, a long hole 5042 and a notch 5043. The fixing ring 5041 is fixedly disposed at the top end of the main turntable 5022. The long holes 5042 are annularly and equidistantly opened on the fixing ring 5041. The notch 5043 is opened on the outer wall of the fixing ring 5041. The switching assembly 505 is rotatably disposed on the inner wall of the fixing ring 5041. One end of the movable assembly 506 away from the switching assembly 505 is movably inserted into the long hole 5042.

[0062] In an embodiment of the present invention, the switching assembly 505 includes a switching disk 5051, a straight chute 5052 and a push rod 5053. The switching disk 5051 is rotatably disposed on the inner wall of the fixing ring 5041. The straight chutes 5052 are annularly and equidistantly opened on the switching disk 5051. One end of the push rod 5053 is fixedly connected to the outer wall of the switching disk 5051. The other end of the push rod 5053 is movably inserted into the notch 5043. The push rod 5053 and the shift lever 5032 are at the same horizontal height.

[0063] As another embodiment of the present invention, the movable component 506 includes a movable block 5061, a slider 5062, a slide bar 5063, an arc plate 5064 and flow filter holes 5065. The slider 5062 is fixedly arranged at the bottom end of the movable block 5061, the slide bar 5063 is fixedly arranged at the top end of the movable block 5061. One end of the slider 5062 away from the movable block 5061 is movably inserted into the straight chute 5052, and one end of the slide bar 5063 away from the movable block 5061 is movably inserted into the long hole 5042. The arc plate 5064 is fixedly arranged on the movable block 5061, and one end of the arc plate 5064 away from the movable block 5061 is movably connected to the inner top wall of the reaction tank 5011. A plurality of flow filter holes 5065 are opened on the arc plate 5064.

[0064] In the present invention, when the stop rod 5032 contacts the push rod 5053 of the switching component 505, the stop rod 5032 pushes the push rod 5053 to rotate. The push rod 5053 drives the switching disk 5051 to rotate on the inner wall of the fixed ring 5041. The switching disk 5051 drives the straight chute 5052 to rotate. The straight chute 5052 rotates and squeezes the slidably connected slider 5062 therein to slide. The slider 5062 drives the movable block 5061, the slide bar 5063 and the arc plate 5064 to move. Since the slide bar 5063 is movably inserted into the long hole 5042 of the fixed ring 5041, due to the limitation of the long hole 5042, the slider 5062 generates an offset. A plurality of sliders 5062 and arc plates 5064, such as Figure 12 shown, achieve the unfolded state. After both materials are melted and fused, at this time, the driving and adjusting mechanism 6 is adjusted to the integral rotation connection state, so that the arc plate 5064 in the unfolded state rotates, not only throwing off some of the raw materials adhered to the arc plate 5064, but also enabling the melted polyester polyol and isocyanate to be fully fused by the rotation of the arc plate 5064, avoiding waste of raw material residues, not only helping to improve the material mixing effect, but also playing a role in cleaning the equipment, reducing the residual accumulation of raw materials inside the equipment, reducing the risks of equipment blockage and corrosion caused by material residues, facilitating the daily cleaning and maintenance of the equipment, helping to extend the service life of the equipment, reducing the equipment maintenance cost, and ensuring the continuity and stability of the production process.

[0065] When the driving and adjusting mechanism 6 rotates in the reverse direction, the stop rod 5032 rotates in a circular arc in the reverse direction to contact the push rod 5053 and push the push rod 5053, so that the push rod 5053 drives the switching disk 5051 to rotate in the reverse direction on the inner wall of the fixed ring 5041. The switching disk 5051 drives the straight chute 5052 to rotate in the reverse direction. The straight chute 5052 rotates and squeezes the slidably connected slider 5062 therein to slide. The slider 5062 drives the movable block 5061, the slide bar 5063 and the arc plate 5064 to move. Since the slide bar 5063 is movably inserted into the long hole 5042 of the fixed ring 5041, due to the limitation of the long hole 5042, the slider 5062 generates an offset, so that it forms as Figure 11In the closed state shown, the unmelted materials are temporarily stored between several closed arc plates 5064 and gradually flow into the interior of the reaction tank 5011 through the flow filtration holes 5065 after being heated and melted. This optimizes the material processing flow, enabling the materials to melt and transfer in a relatively closed and orderly environment, reducing material waste and loss. At the same time, it avoids problems such as uneven reaction or blockage that may be caused by the direct entry of unmelted materials, improving the smoothness and efficiency of the production process.

[0066] In an embodiment of the present invention, the driving and adjusting mechanism 6 includes a motor 601, an electric push rod 602, a fixed insertion block A 603, and an adjusting component 604. The motor 601 and the electric push rod 602 are both connected to the bottom end of the mounting plate 5014. The fixed insertion block A 603 is fixedly arranged at the top end of the mounting plate 5014. One end of the adjusting component 604 is movably sleeved on the main shaft 5021, and the other end of the adjusting component 604 is movably inserted into the mounting plate 5014. The output end of the motor 601 is connected to the main shaft 5021, and the output end of the electric push rod 602 is connected to the adjusting component 604.

[0067] In an embodiment of the present invention, the adjusting component 604 includes a movable sleeve block 6041, a connecting rod 6042, and a slot 6043. The movable sleeve blocks 6041 are symmetrically and movably sleeved on the main shaft 5021. The connecting rod 6042 is connected between the two movable sleeve blocks 6041. The slot 6043 is opened on the movable sleeve block 6041, and the connecting rod 6042 is movably inserted into the through hole 5027.

[0068] A fixed insertion block B 6044 is fixedly arranged at the bottom end of the main turntable 5022. The slot 6043 is adapted to the fixed insertion block A 603 and the fixed insertion block B 6044.

[0069] A fixed sleeve ring 6045 is also fixedly sleeved on one of the movable sleeve blocks 6041. An insertion rod 6046 is fixedly arranged on the outer wall of the fixed sleeve ring 6045. One end of the insertion rod 6046 away from the fixed sleeve ring 6045 is movably inserted into the mounting plate 5014, and one end of the insertion rod 6046 away from the fixed sleeve ring 6045 is also connected to the output end of the electric push rod 602.

[0070] In the present invention, the electric push rod 602 is driven to drive the insertion rod 6046 to move. The insertion rod 6046 drives the fixed collar 6045 to move. The fixed collar 6045 drives the two movable sleeve blocks 6041, the two connecting rods 6042 and the two slots 6043 to move until the slot 6043 at the top is inserted and fixed on the fixed insertion block B6044 fixedly connected to the bottom end of the main turntable 5022 or until the slot 6043 at the bottom is inserted and fixed on the fixed insertion block A603 fixedly connected to the mounting plate 5014; when the slot 6043 is inserted and fixed with the fixed insertion block B6044, the driving and adjusting mechanism 6 is in the full rotation connection state; when the slot 6043 is inserted and fixed with the fixed insertion block A603, the driving and adjusting mechanism 6 is in the adjusting connection state; the two states respectively adapt to the melting and mixing stages of the material. In the melting stage, the full rotation connection state can ensure that the material is uniformly heated and melted in the reaction tank group, improving the melting efficiency and quality. In the mixing stage, the adjusting connection state promotes the material to be mixed in a specific manner, ensuring the sufficiency and uniformity of the mixing. This design of flexibly switching to adapt to the requirements of different production stages optimizes the production process, helps to improve the product quality and production efficiency, and at the same time reduces the operation difficulty of the equipment.

[0071] Embodiment 2

[0072] As Figure 1 shown, the present invention provides a synthesis process of the synthesis device of Embodiment 1, including the following steps:

[0073] Step 1: First, the solid polyester polyol is put in through the feeding port 5012. The solid polyester polyol accumulates between several arc plates 5064 in a closed state. At this time, the slot 6043 is inserted and fixed with the fixed insertion block B6044. The driving motor 601 drives the main shaft 5021, the main turntable 5022 and the external tooth groove 5023 to rotate. The main turntable 5022 drives the fixed insertion block B6044 to rotate. The fixed insertion block B6044 drives the movable sleeve block 6041 and the connecting rod 6042 to rotate. Since the connecting rod 6042 is inserted into the through hole 5027, the bottom turntable 5024 is driven to rotate synchronously. The main turntable 5022 also drives the fixed component 504, the switching component 505 and the movable component 506 at its top to rotate together, so that the solid polyester polyol in the arc plate 5064 of the movable component 506 rotates and is heated;

[0074] Step 2: After the solid polyester polyol melts into a liquid state and gradually flows through the flow filter holes 5065 into the interior of the reaction tank 5011, the solid isocyanate raw material is added through the feed port 5012. Then, the driving and adjusting mechanism 6 drives the main rotating assembly 502, the slave rotating assembly 503, the fixing assembly 504, the switching assembly 505, and the movable assembly 506 to form a revolution state, so that the heating mechanism 3 evenly melts the solid isocyanate placed in the reaction tank group 501. During this melting process, the isocyanate gradually decomposes and merges with the polyester polyol, realizing the premature synthesis of partial prepolymers;

[0075] Step 3: At this time, drive the electric push rod 602 to drive the insertion rod 6046 to move upward. The insertion rod 6046 drives the fixed collar 6045 to move. The fixed collar 6045 drives the two movable sleeve blocks 6041, the two connecting rods 6042, and the two slots 6043 to move until the top slot 6043 is inserted and fixedly connected to the fixed insertion block B6044 at the bottom end of the main turntable 5022. Then, drive the motor 601 to drive the main shaft 5021, the main turntable 5022, and the external tooth groove 5023 to rotate. The external tooth groove 5023 meshes with the driven gear 5031 to drive the driven gear 5031 to rotate. Since the adjusting assembly 604 is in a fixed state, the bottom turntable 5024 and the internal tooth groove 5025 are both in a fixed state, and the driven gear 5031 rotates in a circular orbit around the circular chute 5028 on the bottom turntable 5024. The driven gear 5031 drives the stop lever 5032 to rotate. When the stop lever 5032 contacts the push rod 5053 of the switching assembly 505, the stop lever 5032 pushes the push rod 5053 to rotate. The push rod 5053 drives the switching disk 5051 to rotate on the inner wall of the fixed ring 5041. The switching disk 5051 drives the straight chute 5052 to rotate. The straight chute 5052 rotates and squeezes the sliding block 5062 slidably connected therein to slide. The sliding block 5062 drives the movable block 5061, the sliding rod 5063, and the arc plate 5064 to move. Since the sliding rod 5063 is movably inserted into the long hole 5042 of the fixed ring 5041, due to the limitation of the long hole 5042, the sliding block 5062 generates an offset, and multiple sliding blocks 5062 and arc plates 5064 are in a deployed state;

[0076] Step Four: Drive the electric push rod 602 again to drive the insertion rod 6046 to move downward. The insertion rod 6046 drives the fixed collar 6045 to move, and the fixed collar 6045 drives the two movable sleeve blocks 6041, the two connecting rods 6042 and the two slots 6043 to move until the slot 6043 at the bottom is inserted and fixedly connected to the fixed insertion block A603 fixedly connected to the mounting plate 5014. Then, drive the main rotation assembly 502, the slave rotation assembly 503, the fixed assembly 504, the switching assembly 505 and the movable assembly 506 through the driving and adjusting mechanism 6 to form a revolution state, so that the arc plate 5064 in the unfolded state rotates. This not only throws off some of the raw materials adhered to the arc plate 5064, but also enables the melted polyester polyol and isocyanate to be fully fused through the rotation of the arc plate 5064 for prepolymer synthesis;

[0077] Step Five: Inject the synthesized prepolymer raw materials into the storage tank of the first casting machine, then inject the prepolymer raw materials into the mold through the storage tank of the first casting machine, and inject the liquid low molecular diol into the mold through the storage tank of the second casting machine;

[0078] Step Six: The raw materials injected into the mold are dried to form a polyurethane rubber body;

[0079] Step Seven: Take out the heat-formed polyurethane rubber semi-finished product, use a cutting machine to cut and preliminarily shape the polyurethane rubber, use a grinding machine to grind the polyurethane rubber, perform polishing, and after completing the grinding process, perform boring operation;

[0080] Step Eight: After completing the above steps, inspect the polyurethane rubber, and it can be shipped out if it is qualified.

[0081] The embodiments disclosed in the present invention are preferred embodiments, but not limited thereto. Those of ordinary skill in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not depart from the spirit of the present invention, they are within the protection scope of the present invention.
