Description

Technical Field

[0001] This invention relates to the field of TPU material processing technology, and more specifically to a material forming apparatus for the production of TPU materials. Background Technology

[0002] Thermoplastic polyurethane elastomer, also known as thermoplastic polyurethane rubber, or TPU for short, is a (AB)n-type block linear polymer. It is a type of elastomer that can be plasticized by heating and dissolved by solvents. It has excellent comprehensive properties such as high strength, high toughness, wear resistance, and oil resistance. It has good processing performance and is widely used in defense, medical, food and other industries. In the production and processing of TPU materials, the raw materials are usually mixed and stirred evenly before molding. The molding operation generally involves injecting the mixed raw materials into a mold and then waiting for it to solidify.

[0003] A search revealed that patent CN115214094A discloses a TPU cutting board injection molding process and device. This device can simultaneously perform injection molding and cooling of multiple molds, and can also remove the cutting board through a suction nozzle, thus automating the injection molding, cooling, and gripping process of the cutting board. This improves the smoothness of the equipment operation, reduces the time required for the equipment process, and reduces the input of manpower and material resources.

[0004] While existing devices can perform injection cooling operations on multiple molds simultaneously, they are in a stopped state during the cooling period after each injection, which is not conducive to the efficiency of the molding process. Moreover, the injection process requires multiple operations, such as starting the conveyor belt to align the template assembly, starting the first cylinder to clamp the template, and starting the nozzle to inject. Although this improves the continuity of molding, the operation is still relatively complicated. In view of this, the present invention proposes a material molding device for the production of TPU material. Summary of the Invention

[0021] Beneficial effects

[0022] The technical solution provided by this invention has the following advantages compared with known public technologies:

[0023] 1. This invention is equipped with a drive mechanism. When the mold body moves onto it, the drive mechanism slightly lowers, causing the transmission gear to stop driving the conveyor belt. The injection component then injects liquid TPU material into the mold body. As the amount of material in the mold body increases, the pressure on the lifting seat also increases. This causes the transmission gear in the drive mechanism to mesh with the first toothed post on the inner bottom surface of the conveyor belt. This, in turn, causes the conveying component to continue transporting the mold body filled with material towards the temporary storage component. This allows the device to automatically complete a series of processes without operator intervention: conveying the mold body, injecting material, removing the mold body and replacing it with the next mold body, and moving the mold body filled with material to the temporary storage area for cooling. Compared to existing technologies, this is more seamless. Throughout the process, operators only need to place the mold body on the device, greatly improving the efficiency of the TPU material molding process. The design is ingenious and highly practical.

[0024] 2. The present invention is equipped with an injection component, which injects raw material into the mold body as the mold body presses the lifting seat down, and closes as the lifting seat returns to its original position after the mold body is removed. This allows for targeted material feeding actions and flexible judgment of the position of the mold body and changes in the amount of raw material inside, making the operation of the device more intelligent.

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0036] A material forming apparatus for the production of TPU material, reference Figure 1-8 It includes a base 1, and a conveying assembly 3 is provided inside the base 1. The conveying assembly 3 includes a conveyor belt 4 slidably connected to the inner wall of the base 1, and two mold bodies 5 are provided on the conveyor belt 4.

[0037] The conveying assembly 3 also includes a drive mechanism 6. The drive mechanism 6 includes a lifting seat 7 elastically connected to the inner bottom surface of the base 1. A rotating shaft 8 is rotatably connected to the lower ends of both sides of the lifting seat 7. A transmission gear 9 is coaxially fixedly connected to both ends of the rotating shaft 8. Multiple first gear columns 10, meshing with the transmission gear 9, are uniformly fixed to both sides of the inner wall of the conveyor belt 4. A motor 11 is coaxially fixedly connected to the end of one of the rotating shafts 8. A guide groove 12 with a sloping structure (lower at the front and higher at the back) is opened on the top surface of the lifting seat 7. Inclined grooves 13 are opened on both sides of the guide groove 12. A bottom groove 14 is opened at the front end of the bottom of the guide groove 12. A first magnet is embedded in the bottom surface of the bottom groove 14. Iron 15, a second magnet 16 is fixed on the bottom surface of the mold body 5 to attract and cooperate with the first magnet 15, and the conveying assembly also includes a plurality of gear columns 18 rotatably connected inside the base 1. The gear columns 18 are used to support the conveyor belt 4 and prevent it from sinking under the gravity of the mold body 5. The gear columns 18 are meshed with the first gear column 10. The distance between the gear column 18 and the inner bottom surface of the base 1 is smaller than the distance between the transmission gear 9 and the inner bottom surface of the base 1. The inner wall of the base 1 has a groove 19 that slides with the conveyor belt 4. The upper middle part of the groove 19 is set in a U-shaped structure with the concave surface facing downward. The bottom surface of the transmission gear 9 is connected to the first gear column 10. The inner bottom surface of the conveyor belt 4 has a clearance fit, which provides sufficient operating space for the transmission gear 9 and prevents the conveyor belt 4 from loosening due to prolonged operation. A through groove 20 is provided in the middle of the conveyor belt 4 to slide against the lifting seat 7. The lifting seat 7 has a U-shaped structure, and the front end of the bottom of the second magnet 16 has a sloping structure. Shaft grooves 37 are provided on the inner walls of both sides of the base 1 to slide against the ends of the rotating shaft 8. The shaft groove 37 near the motor 11 is connected to the outside of the base 1. Two limiting blocks 38 are symmetrically fixed on the outer wall of the motor 11 near the base 1. A sliding groove is provided on the side wall of the base 1 to slide against the limiting blocks 38. The lower end of the movable plate 28 is connected and fixed to the middle of the bottom surface of the lifting seat 7. The lower part of the lifting seat 7 is also symmetrically connected to four connecting rods 41. The two connecting rods 41 on the same side are arranged in a cross shape. The four connecting rods 41 are rotatably connected through a central shaft 42. The lower ends of the two connecting rods 41 on the inner side and the two connecting rods 41 on the outer side are hinged to a sliding seat 43. The inner bottom surface of the base 1 is provided with a sliding groove 44 that slides with the sliding seat 43. Two support springs 45 are symmetrically fixed between the bottom surface of the lifting seat 7 and the inner bottom surface of the base 1.

[0038] Workers can place the mold body 5, which is to be used for the finished product, on the conveyor belt 4 of this device. Before placing it, a second magnet 16 needs to be welded or glued to the front end of the bottom of the mold body 5. Then, the drive mechanism 6 can be used to drive the conveyor assembly 3. When the mold body 5 is conveyed to the position of the drive mechanism 6, its end will be buffered by the rear inclined groove 13 and will not be stuck by the rear wall of the lifting seat 7. At this time, although the front end of the mold body 5 rests on the inclined groove 13, its rear end is still on the conveyor belt 4. Therefore, part of the weight of the mold body 5 will be distributed on the conveyor belt 4. In this way, the pressure initially generated by the mold body 5 on the lifting seat 7 cannot completely disengage the transmission gear 9 from the first tooth. As the mold body 5 is slowly pushed onto the lifting seat 7, the point where it contacts the junction of the inclined groove 13 and the guide groove 12 gradually moves backward. Before the rear end of the mold body 5 leaves the conveyor belt 4, this contact point will move to a position behind the centerline of the mold body 5. Then, under the action of gravity, the mold body 5 will flip forward and slide forward along the guide groove 12. At this time, the weight of the mold body 5 will be fully applied to the lifting seat 7. Then the lifting seat 7 will move down, and the sliding seat 43 will slide outward along the sliding groove 44. The included angle of the two connecting rods 41 arranged in a cross shape on the same side will decrease, and the support spring 45 will also be compressed under force. Under the action of the connecting rods 41, the lifting seat 7 will... The vertical movement will not deviate from a straight line, and such a change will cause the transmission gear 9 to disengage from the first toothed column 10. Consequently, the conveyor assembly 3, which is no longer driven by the drive mechanism 6, will stop. The rotating shaft 8 and the transmission gear 9 will then rotate on their own at the position inside the conveyor belt 4. At the same time, the second magnet 16, which slides down the bottom surface of the mold body 5 along the guide groove 12, will insert into the bottom groove 14 and attract each other to the first magnet 15. Then, the mold body 5 will be fixed directly below the injection assembly 17. During its sliding down, the injection assembly 17 is already injecting TPU material into the mold body 5. When the amount of material inside the mold body 5 is close to saturation, its weight will press down on the lifting seat 7 and the transmission... Gear 9 is driven to a position close to the inner bottom surface of conveyor belt 4, so that transmission gear 9 will mesh with the first tooth post 10 on the lower inner wall of conveyor belt 4, and conveyor belt 4 will start to move again. During the descent of lifting seat 7, because guide groove 12 is designed at an angle, the front end of mold body 5 will first come into contact with the top surface of conveyor belt 4. Then, under the pressure of conveyor belt 4, mold body 5 will cause the second magnet 16 to separate from the first magnet 15. When conveyor belt 4 starts to operate again, mold body 5 can be transported forward without obstruction. At this time, injection component 17 will also stop injecting raw materials into mold body 5. Finally, mold body 5 will be transported to temporary storage component 2 by conveying component 3.

[0039] An injection assembly 17 is installed in the middle of the top surface of the base 1. The injection assembly 17 is used to fill the mold body 5 with liquid TPU material. The injection assembly 17 includes a barrel 21. A glass plate 49 is embedded in the outer wall of the barrel 21 near the motor 11. The lower end of the barrel 21 has a U-shaped structure and is connected and fixed to the top surface of the base 1. A pump body 22 is fixed on one side of the top surface of the barrel 21. Both ends of the pump body 22 are connected to conduits 23. The end of the conduit 23 near the barrel 21 penetrates the top surface of the barrel 21. Extending into its interior, the bottom surface of the material cylinder 21 has a discharge port 24. A baffle 25 is located in the middle of the discharge port 24. A sealing ring 26 is fitted onto the middle of the outer wall of the baffle 25, and the sealing ring 26 is in pressure contact with the inner wall of the discharge port 24. A fixed shaft 27 is fixed to the middle of the outer wall of the baffle 25 on the side away from the motor 11. The end of the fixed shaft 27 extends through the inner wall of the discharge port 24 to the outside and is rotatably connected to the material cylinder 21. A movable plate 28 is located on the outer wall of the material cylinder 21 on the side away from the motor 11. The movable plate 28 is... The L-shaped structure has a groove 39 on the outer wall of the base 1 away from the motor 11, which slides with the movable plate 28. A side groove 29 is provided on the upper part of the movable plate 28 near the material cylinder 21. A half gear 30 is coaxially fixedly connected to the end of the fixed shaft 27 relative to the side groove 29. The upper part of the inner wall of the side groove 29 has a linear and evenly spaced structure with multiple second toothed columns 31 that mesh with the half gears 30. The second toothed columns 31 are rotatably connected to the side wall of the side groove 29 through a hinge shaft 32. A torsion spring 33 is sleeved in the middle of the hinge shaft 32. A groove 34 is provided on the inner wall of the side groove 29 relative to the lower part of the hinge shaft 32, which rotates with the second toothed columns 31. The two ends of the torsion spring 33 are respectively connected and fixed to the bottom surface of the second toothed column 31 and the top surface of the groove 34. A circular groove 35 is provided inside the material cylinder 21 relative to the middle of the fixed shaft 27. A coil spring 36 is sleeved on the outer wall of the fixed shaft 27 relative to the circular groove 35. The outer end of the coil spring 36 is connected and fixed to the inner wall of the circular groove 35.

[0040] During the descent of the lifting seat 7 and the cessation of the conveying assembly 3, the movable plate 28 on it descends and, through the second toothed column 31 in the side groove 29, actuates the half gear 30 to rotate 180 degrees. The half gear 30 then drives the fixed shaft 27 and the baffle 25 to rotate 180 degrees, opening the discharge port 24. The TPU material injected into the material cylinder 21 through the pump body 22 and conduit 23 flows out of the discharge port 24 and into the mold body 5. When the mold body 5 opens the discharge port 24, its front end already extends beyond the front wall of the discharge port 24, preventing material leakage. Subsequently, when the amount of material in the mold body 5 reaches a threshold, the uppermost second toothed column 31 moves below the half gear 30. At this point, without the actuation of the second toothed column 31, the half gear 30 will be engaged by the coil spring 36. The material returns to its original position under the rebound force and re-seals the outlet 24 through the baffle 25. Before the outlet 24 is sealed, the rear end of the mold body 5 will not be conveyed to the front side of the rear wall of the outlet 24. This allows for fixed-point and quantitative injection. Furthermore, the second tooth column 31 is hinged to the inner wall of the side groove 29 through the hinge shaft 32. As the movable plate 28 moves upward with the lifting seat 7, the second tooth column 31 will be squeezed by the half gear 30 and rotate into the groove 34. When its height exceeds the half gear 30, it will pop out under the rotation force of the torsion spring 33 to wait for the next actuation of the half gear 30. This design ensures that the outlet 24 will not be reopened when the lifting seat 7 rebounds, thus avoiding waste of raw materials. In addition, the staff can observe the amount of raw materials stored in the material cylinder 21 through the glass plate 49 and replenish the raw materials in time.

[0041] A temporary storage component 2 is provided on the front side of the base 1. The temporary storage component 2 includes a placement seat 46 fixed on the front side of the base 1. The placement seat 46 has multiple rollers 47 rotatably connected in a linear and equally spaced structure inside. A connecting plate 48 is provided between the roller 47 at the rear end and the front part of the conveyor belt 4. The connecting plate 48 slides in contact with the roller 47 and the conveyor belt 4. The connecting plate 48 is connected and fixed to the base 1.

[0042] The raw material in the mold body 5, which is conveyed forward from the bottom of the injection component 17 by the conveyor belt 4, will gradually self-level during the movement. Then it will be transported to the temporary storage component 2 by the conveying component 3. The mold body 5 will then move from the connecting plate 48 to the multiple rollers 47 for resting. The mold body 5 previously sent to the multiple rollers 47 will be pushed forward by the subsequent mold body 5 to facilitate the cooling of the raw material in the mold body 5. After the resting time is satisfied, it will be demolded separately.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
