Technical Field
[0001] This application relates to the field of load-bearing device technology, and in particular to load-bearing devices using polyurethane particles. Background Technology
[0002] Polyurethane particles, as an important polymer material, are widely used in many fields such as building materials, automotive industry, and packaging materials due to their excellent physical properties and chemical stability. Especially in the production of thermoplastic polyurethane elastomer (TPU) films, polyurethane particles are the main raw material, and their quality and processing methods directly affect the performance and quality of the final product.
[0003] In existing polyurethane granule loading structures, the funnel is a common loading method. This structure is simple, inexpensive, and can achieve basic granule loading and dispensing functions. However, traditional funnel loading structures have certain limitations, especially in accurately controlling the quantity of polyurethane granules dispensed. This makes it difficult to precisely control the amount of polyurethane granules dispensed during the production process, which may affect the production efficiency and product quality of TPU films.
[0004] Based on existing technology, although the funnel structure can complete the basic loading task, it cannot effectively control the amount of polyurethane particles fed in. This poses a challenge to the precise control of raw material ratio and quality stability in the TPU film production process, thereby reducing the production efficiency of the equipment. Utility Model Content
[0005] The purpose of this application is to address the problem that the existing funnel structure cannot effectively control the amount of polyurethane particles fed, which poses a challenge to the precise control of raw material ratio and quality stability in the TPU film production process, thereby reducing the production efficiency of the equipment. This application provides a load-bearing device for polyurethane particles.
[0006] To achieve the above objectives, this application specifically adopts the following technical solution:
[0007] A load-bearing device for polyurethane granules includes a funnel with symmetrically arranged inlets at one end. A base plate is slidably connected inside the inlets. A support plate is symmetrically fixedly connected to one end of the funnel. A guide groove is provided at one end of the support plate. A guide rod is slidably connected inside the guide groove. One end of the guide rod is fixedly connected to the base plate. An electric actuator is fixedly connected to one end of the support plate. The output end of the electric actuator is fixedly connected to the guide rod. A top plate is fixedly connected inside the funnel. Multiple discharge ports are evenly arranged at one end of the top plate.
[0008] By adopting the above technical solution, and by setting up the electric push rod and guide slide rod, and the guide slide rod and base plate to work together, it is convenient to drive the two base plates to move closer or further apart along the length of the guide slide when the electric push rod is started. This allows the two base plates to sequentially cover or uncover multiple feeding ports, thereby achieving effective control over the amount of material discharged downward through the feeding ports of the funnel. This facilitates precise control of the raw material ratio in the TPU film production process and improves the production efficiency of the device.
[0009] Furthermore, a groove is provided on one side of the funnel, and a through groove communicating with the inside of the funnel is provided on the inner side of the groove. A reciprocating slider is slidably connected inside the through groove, and a reciprocating slide rod is rotatably connected to one end of the reciprocating slider. One end of the reciprocating slide rod extends into the inside of the funnel, and a drive assembly for driving the reciprocating slide rod to move back and forth along the length direction of the groove is installed at one end of the funnel.
[0010] By adopting the above technical solution, and by setting the drive component to work in conjunction with the reciprocating slider, the through groove, and the reciprocating slide rod, when the material piles up on the top of the top plate and causes blockage at the discharge port, the drive component is activated to drive the reciprocating slider to move back and forth along the length of the through groove. This allows the reciprocating slide rod to loosen the material piled up on the top of the top plate, thereby reducing the blockage at the discharge port caused by the accumulation of material on the top of the top plate and improving the practicality of the device.
[0011] Furthermore, the drive assembly includes a traction rod installed inside the groove, one end of the reciprocating slide rod is rotatably connected to the traction rod, one end of the traction rod is hinged to a connecting rod, one end of the funnel is fixedly connected to a drive motor, the output end of the drive motor is fixedly connected to a drive wheel, and one end of the drive wheel is eccentrically hinged to the connecting rod.
[0012] By adopting the above technical solution and setting the connecting rod and the drive wheel to work together, the starting drive motor can drive the drive wheel to rotate the connecting rod eccentrically, thereby causing the connecting rod to move the traction rod back and forth along the length of the groove, which effectively improves the practicality of the device.
[0013] Furthermore, a plurality of stirring rods are uniformly fixedly connected to one end of the reciprocating slide rod, and a transmission gear is fixedly connected to the other end of the reciprocating slide rod. A transmission rack that meshes with the transmission gear is fixedly connected to the inner top of the groove.
[0014] By adopting the above technical solution, and by setting up the cooperation between the transmission gear and the transmission rack, when the traction rod drives the reciprocating slide bar to move back and forth along the length of the groove, the transmission gear and the transmission rack mesh, and the reciprocating slide bar rotates back and forth, which effectively improves the loosening efficiency of the reciprocating slide bar on the top of the top plate.
[0015] Furthermore, an anti-overflow plate is fixedly connected to one end of the reciprocating slider, and the anti-overflow plate is in contact with the inner side of the through groove.
[0016] By adopting the above technical solution, and by setting up the anti-overflow plate in conjunction with the through groove, when the reciprocating slider moves back and forth along the length of the through groove, the anti-overflow plate will shield the inside of the through groove, thereby reducing the overflow of raw materials inside the funnel through the through groove and improving the practicality of the device.
[0017] Furthermore, multiple support rods are symmetrically and evenly fixedly connected to the inner side of the funnel, and one end of the base plate is mounted on the top of the support rods.
[0018] By adopting the above technical solution, and by setting multiple support rods in conjunction with two base plates, it is convenient to provide support for the end of the base plate that slides along the length of the guide groove, thereby effectively improving the support strength of the base plate.
[0019] Furthermore, one end of the support rod is rotatably fitted with an abutment roller sleeve, and the support rod forms a rolling abutment with the base plate through the abutment roller sleeve.
[0020] By adopting the above technical solution, and by setting the contact roller sleeve to form a rolling contact with the base plate, the wear between the support rod and the base plate is effectively reduced, and the service life of the device is extended.
[0021] Furthermore, the inner side of the funnel is coated with an organosilicon waterproof coating.
[0022] By adopting the above technical solution and setting an organosilicon waterproof coating, the corrosion resistance of the inner side of the funnel is effectively improved, and the service life of the device is extended.
[0023] In summary, this application includes at least one of the following beneficial effects:
[0024] 1. By setting up the electric push rod and guide slide rod, and the guide slide rod and base plate to work together, it is easy to drive the two base plates to move closer or further apart along the length of the guide slide when the electric push rod is started. This allows the two base plates to sequentially cover or uncover multiple feeding ports, thereby achieving effective control over the amount of material discharged downward through the feeding port of the funnel. This facilitates precise control of the raw material ratio in the TPU film production process and improves the production efficiency of the device.
[0025] 2. By setting up the drive assembly in conjunction with the reciprocating slider, through groove, and reciprocating slide rod, when the material piles up on the top of the top plate and causes blockage at the discharge port, the drive assembly is activated to drive the reciprocating slider to move back and forth along the length of the through groove. This loosens the material piled up on the top of the top plate, reducing the blockage at the discharge port caused by material accumulation and improving the practicality of the device.

[0032] The following is in conjunction with the appendix Figure 1 —4 provides further detailed description of this application.
[0033] This application discloses a load-bearing device for polyurethane particles.
[0034] Reference Figure 1 - Figure 3 The load-bearing device for polyurethane particles includes a funnel 1, with symmetrically arranged inlets 2 at one end of the funnel 1, a base plate 3 slidably connected inside the inlet 2, a support plate 4 symmetrically fixedly connected to one end of the funnel 1, a guide groove 5 at one end of the support plate 4, a guide rod 6 slidably connected inside the guide groove 5, one end of the guide rod 6 fixedly connected to the base plate 3, an electric push rod 7 fixedly connected to one end of the support plate 4, the output end of the electric push rod 7 fixedly connected to the guide rod 6, and a top plate 8 fixedly connected inside the funnel 1, with multiple discharge ports 9 evenly arranged at one end of the top plate 8.
[0035] Among them, multiple support rods 22 are symmetrically and evenly fixedly connected to the inner side of the funnel 1, and one end of the bottom plate 3 is supported on the top of the support rods 22.
[0036] Furthermore, one end of the support rod 22 is rotatably fitted with an abutment roller sleeve 23, and the support rod 22 forms a rolling abutment with the base plate 3 through the abutment roller sleeve 23;
[0037] Furthermore, the inner side of funnel 1 is coated with an organosilicon waterproof coating.
[0038] In use, the inner side of the funnel 1 is first made more rust-resistant by setting an organic silicone waterproof coating, thus extending the service life of the funnel 1. Then, when the material is discharged downward through the discharge port 9 through the funnel 1, the electric push rod 7 is activated to drive the guide slide rod 6 to move the base plate 3 along the length of the guide slide 5. This causes the two base plates 3 to move away from or towards each other along the length of the guide slide 5. One end of the two base plates 3 rolls against the support rod 22 through the contact roller sleeve 23. At the same time, the two base plates 3 sequentially unblock or sequentially block multiple discharge ports 9, thereby achieving effective control over the amount of material discharged downward through the funnel 1 through the discharge port 9. This facilitates precise control of the raw material ratio in the TPU film production process and improves the production efficiency of the device.
[0039] Reference Figure 1 and Figure 2 , Figure 4 A groove 10 is provided on one side of the funnel 1, and a through groove 11 communicating with the inside of the funnel 1 is provided on the inner side of the groove 10. A reciprocating slider 12 is slidably connected inside the through groove 11. A reciprocating slide rod 13 is rotatably connected to one end of the reciprocating slider 12. One end of the reciprocating slide rod 13 extends into the inside of the funnel 1. A drive assembly for driving the reciprocating slide rod 13 to reciprocate along the length direction of the groove 10 is installed at one end of the funnel 1.
[0040] The drive assembly includes a traction rod 14 installed inside the groove 10, one end of the reciprocating slide rod 13 is rotatably connected to the traction rod 14, one end of the traction rod 14 is hinged to a connecting rod 15, one end of the funnel 1 is fixedly connected to a drive motor 16, the output end of the drive motor 16 is fixedly connected to a drive wheel 17, and one end of the drive wheel 17 is eccentrically hinged to the connecting rod 15.
[0041] Furthermore, a plurality of stirring rods 18 are uniformly and fixedly connected to one end of the reciprocating slide rod 13, and a transmission gear 19 is fixedly connected to the other end of the reciprocating slide rod 13. A transmission rack 20 that meshes with the transmission gear 19 is fixedly connected to the inner top of the groove 10.
[0042] Furthermore, an anti-overflow plate 21 is fixedly connected to one end of the reciprocating slider 12, and the anti-overflow plate 21 is in contact with the inner side of the through groove 11.
[0043] When in use, when a large amount of raw material accumulates on the top of the top plate 8 inside the funnel 1, the drive motor 16 is started to drive the drive wheel 17 to rotate, and the drive wheel 17 and the connecting rod 15 rotate eccentrically. This causes the connecting rod 15 to drive the traction rod 14 to reciprocate along the length of the groove 10, and the traction rod 14 to drive the reciprocating slide rod 13 to reciprocate along the length of the reciprocating slider 12 along the through groove 11. This causes the reciprocating slide rod 13 to reciprocate inside the funnel 1, so as to loosen the raw material accumulated on the top of the top plate 8, thereby reducing the blockage of the discharge port 9 caused by the accumulation of raw material on the top of the top plate 8.
[0044] Furthermore, when the drive traction rod 14 drives the reciprocating slide rod 13 to move back and forth along the length of the groove 10, it drives the transmission gear 19 to mesh with the transmission rack 20, and at the same time, the transmission gear 19 drives the reciprocating slide rod 13 and the stirring rod 18 to rotate back and forth, thereby improving the loosening efficiency of the reciprocating slide rod 13 on the top of the top plate 8.
[0045] When the reciprocating slider 12 moves along the length of the channel 11, it drives the anti-overflow plate 21 to slide synchronously against the inner side of the funnel 1, thus shielding the inner side of the channel 11 and reducing the overflow of raw materials inside the funnel 1 through the channel 11, thereby improving the practicality of the device.
[0046] The implementation principle of the load-bearing device for polyurethane particles in this embodiment is as follows: First, the electric actuator 7 drives the guide slide rod 6 to move the base plate 3 along the length direction of the guide slide 5, and drives the two base plates 3 to move away from or towards each other along the length direction of the guide slide 5. One end of the two base plates 3 forms a rolling contact with the support rod 22 through the contact roller sleeve 23. At the same time, the two base plates 3 can sequentially unblock or sequentially block multiple discharge ports 9, thereby achieving effective control over the amount of material discharged downward from the funnel 1 through the discharge ports 9.
[0047] At the same time, the drive motor 16 is started to drive the drive wheel 17 to rotate, and the drive wheel 17 and the connecting rod 15 rotate eccentrically. This causes the connecting rod 15 to drive the traction rod 14 to reciprocate along the length of the groove 10, and the traction rod 14 to drive the reciprocating slide bar 13 to reciprocate along the length of the reciprocating slider 12 along the through groove 11. This causes the reciprocating slide bar 13 to reciprocate inside the funnel 1, so as to loosen the raw materials accumulated on the top of the top plate 8.
[0048] Furthermore, when the drive traction rod 14 drives the reciprocating slide rod 13 to move back and forth along the length of the groove 10, it drives the transmission gear 19 to mesh with the transmission rack 20, and at the same time, the transmission gear 19 drives the reciprocating slide rod 13 and the stirring rod 18 to rotate back and forth, thereby improving the loosening efficiency of the reciprocating slide rod 13 on the top of the top plate 8.
[0049] When the reciprocating slider 12 moves along the length of the channel 11, it drives the anti-overflow plate 21 to slide synchronously against the inner side of the funnel 1, and forms a shield on the inner side of the channel 11 to reduce the overflow of raw materials inside the funnel 1 through the channel 11.
