[0003] TPV material is usually processed into elastomer granules, and then elastomer granules are used as raw materials for finished product processing. After TPV elastomer granules are processed, they are usually transported to TPV elastomer granule storage bin for storage. When needed, TPV elastomer granules in the storage bin are discharged through the discharge device arranged on the storage bin, and then transported to the next production process through transfer container or packaged for sale. Since TPV elastomer granules have certain elasticity and large friction between each other, they are prone to block at the discharge port, affecting the smoothness of TPV elastomer granule discharge.

[0004] The existing TPV elastomer granule storage bin usually needs manual stirring of TPV elastomer granules when discharging TPV elastomer granules, which is inconvenient to operate. Some TPV elastomer granule storage bins are provided with electric stirring devices, but the electric stirring devices are prone to clamp TPV elastomer granules between the stirring device and the wall of the storage bin, causing breakage of TPV elastomer granules.

[0019] 3. The elastic fixing between the scraper and the stirring rod formed by the elastic metal sheet can change the radial position of the scraper while reducing the change in the circumferential position of the scraper, thereby ensuring that the scraper has stronger circumferential scraping ability for the TPV elastomer particles; the scraper composed of a scraping rod and an elastic scraping head fixed outside the scraping rod can form reliable contact with the bin chamber side wall through the elastic deformation of the elastic scraping head, and the buffer of the scraping force generated by the elastic scraping head, thereby ensuring the scraping effect on the TPV elastomer particles while reducing the damage of the TPV elastomer particles.

[0020] 4. The anti-pinch turning plate arranged on the rotary valve plate 43 on one side of the valve plate hole can be used to pull out the TPV elastomer particles located between the rotary valve plate and the pipeline blocking plate when the blocking plate hole is blocked by the rotary valve plate rotating to close the pipeline blocking plate, thereby preventing the edges of the rotary valve plate and the pipeline blocking plate from pinching off the TPV elastomer particles when the discharge device is closed, and causing excessive damage to the TPV elastomer particles.

DETAILED DESCRIPTION

[0027] The specific embodiments of the utility model will be described in detail below in conjunction with the drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the utility model, and are not used to limit the utility model.

[0028] In the description of the utility model, it should be pointed out that, unless otherwise explicitly specified and limited, the terms "set", "connected" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrally connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication inside two elements or the interaction relationship between two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0029] One embodiment of the TPV elastomer particle storage bin with stirring mechanism of the utility model is as follows: Figure 1 And Figure 2As shown, it comprises a bin 1, a stirring mechanism 2 and a stirring driving mechanism 3. The bin 1 can be various containers with large capacity for storing TPV elastomer particles. The bin 1 is usually provided with supporting feet and supported on the ground through the supporting feet, so that the bin 1 is located at a certain height from the ground. The bin 1 is provided with a discharge device 4, through which the TPV elastomer particles stored in the bin 1 can be discharged and collected into a container or a packaging bag below the discharge device 4, facilitating the delivery of the TPV elastomer particles to the next processing procedure for further processing or as a product for sale.

[0030] The stirring mechanism 2 comprises a rotating shaft 21, a support frame 22, stirring rods 23 and a scraping member 24. The rotating shaft 21 is arranged in the bin 1 and rotatably connected to the side wall of the bin 1 at both ends. A driving wheel is usually fixedly connected to one end of the rotating shaft 21, through which the rotating shaft 21 can be driven to rotate in the bin 1. The support frame 22 can be various frame bodies with a central symmetric structure. The center of symmetry of the support frame 22 is fixed on the rotating shaft 21, so that the support frame 22 can rotate with the rotating shaft 21.

[0031] The stirring rods 23 are usually provided in multiple numbers and fixed on the support frame 22 symmetrically, so that each stirring rod 23 is parallel to the rotating shaft 21. When the support frame 22 rotates, it can drive the multiple stirring rods 23 to rotate in the bin, producing a stirring effect on the TPV elastomer particles stored in the bin 1, promoting the flow of the TPV elastomer particles and reducing the adhesion between the TPV elastomer particles, which is conducive to the flow of the TPV elastomer particles to the inlet of the discharge device 4 and the discharge through the discharge device 4.

[0032] The scraping member 24 is fixed to the outside of the stirring rod 23 through an elastic connection structure, which can be a spring, an elastic connecting piece or various sealed compressible containers. The elastic connection structure can push the scraping member 24 to move away from the stirring rod 23, so that the scraping member 24 can periodically abut against the side wall of the bin 1 to scrape off the TPV elastomer particles adhering to the side wall of the bin 1, reducing the residence of the TPV elastomer particles in the bin 1. When the TPV elastomer particles adhere firmly to the side wall of the bin 1 and cannot be scraped off at once by the scraping member 24, the elastic deformation of the elastic connection structure forms a gap between the scraping member 24 and the side wall of the bin 1, which is conducive to the passage of the TPV elastomer particles and prevents the TPV elastomer particles from being clamped in the hard gap between the scraping member 24 and the side wall of the bin 1, causing tearing or damage to the TPV elastomer particles.

[0033] The stirring driving mechanism 3 is drivingly connected with the rotating shaft 21, and is usually connected with a driving wheel (not shown in the figure) on the rotating shaft 21 through a transmission structure to form a speed reduction transmission connection, so as to drive the rotating shaft 21 to rotate in the chamber 1 at a slow speed, thereby driving the flow of the TPV elastomer particles in the chamber 1 through the rotation of the stirring rod 23 and the scraping member 24, and improving the flow of the TPV elastomer particles discharged through the discharging device 4.

[0034] In a preferred embodiment, as shown in Figure 2 , a support frame 22 is arranged at each end of the rotating shaft 21, and when the rotating shaft 21 is installed in the chamber, the two support frames 22 are located on the two sides of the chamber 1 in the length direction, adjacent to the side wall of the chamber 1.

[0035] Each support frame 22 includes a circular support frame 221 and a plurality of support rib rods 222 of equal length. The plurality of support rib rods 222 are uniformly arranged at different positions on the same axial section of the rotating shaft 21, one end of each support rib rod 222 is fixedly connected with the rotating shaft 21, and the other end extends along the radial direction of the rotating shaft 21 and is fixedly connected to the inner side of the support frame 221.

[0036] The two ends of the stirring rod 23 are fixedly connected to the side surfaces on the opposite sides of the two support frames 221. The inner side wall of the chamber 1 is arranged in a shape of a circle at the lower part and a rectangle at the upper part in the cross section perpendicular to the length direction, and when the rotating shaft 21 rotates, the scraping member 24 is in contact with the circular part of the lower part of the inner side wall of the chamber 1 under the action of the elastic connection structure, thereby scraping the TPV elastomer particles adhered to the side wall of the chamber 1.

[0037] In a further preferred embodiment, as shown in Figure 2 and Figure 3 , the scraping member 24 includes a scraping rod 241 and an elastic scraping head 242. The scraping rod 241 is usually made of hard materials such as metal, and the scraping rod 241 is fixedly connected to the outer side surface of the stirring rod 23 through the elastic connection structure to ensure the reliability and stability of the connection structure. The elastic scraping head 242 is usually made of flexible materials such as rubber and plastic, and the elastic scraping head 242 is fixedly connected to the outer side surface of the scraping rod 241, that is, the side surface away from the stirring rod 23. Under the elastic force of the elastic connection structure, the elastic scraping head 242 is in contact with the inner side wall of the chamber 1 to ensure that a reliable surface contact is formed therebetween, and the possibility of damaging the TPV elastomer particles can be reduced through the elastic deformation of the elastic scraping head 242 itself.

[0038] In a specific embodiment, as shown in Figure 2 and Figure 3As shown, the scraping rod 241 is fixed on the stirring rod 23 by the elastic sheet 243. Generally, the elastic sheet 243 is made of a metal material with good elasticity, such as 65Mn material, and is bent to form a shape similar to "U". One end of the "U"-shaped elastic sheet 243 is fixed on the outer side of the stirring rod 23, and the other end is fixed on the inner side of the scraping rod 241. The elastic deformation of the elastic sheet 243 can change the distance between the scraping rod 241 and the stirring rod 23. Using the elastic sheet 243 as the elastic connecting structure can reduce the possibility of the TPV elastomer particles being stuck in the elastic connecting structure, which is beneficial to prevent the damage of the TPV elastomer particles.

[0039] In a preferred embodiment, as shown in Figure 2 and Figure 3 In the stirring mechanism 2, an axial pushing member 25 is further provided, which is in the shape of a long strip. The axial pushing member 25 is fixed on the outer side of the stirring rod 23, and the length direction thereof is obliquely intersected with the length direction of the stirring rod 23. The outer side of the axial pushing member 25, that is, the side away from the stirring rod 23, is in the shape of a circular arc in the projection on the plane perpendicular to the rotating shaft 21. When the rotating shaft 21 rotates, the axial pushing member 25 can push the TPV elastomer particles in the chamber 1 to form a movement trend parallel to the direction of the rotating shaft 21, so that the TPV elastomer particles flow along the rotating shaft 21 to the position of the discharging device 4.

[0040] In a further preferred embodiment, as shown in Figure 2 and Figure 3 The axial pushing member 25 comprises a pushing rod 251 and an elastic pushing head 252. The pushing rod 251 is made of a hard material such as metal, and is fixed on the outer side of the stirring rod 23. The hard pushing rod 251 is beneficial to improve the position stability of the elastic pushing head 252. The elastic pushing head 252 is made of a flexible material such as rubber or silica gel, and is fixed on the outer side of the stirring rod 23, that is, the side away from the stirring rod 23, by clamping and / or gluing. The elastic pushing head 252 made of a flexible material is beneficial to form reliable contact between the elastic pushing head 252 and the inner side wall of the chamber 1.

[0041] In another preferred embodiment, as shown in Figure 3As shown, a plurality of, such as two, axial pushing members 25 are fixed on the same stirring rod 23. The two axial pushing members 25 are usually fixed on the stirring rod 23 at the corresponding positions of the discharge device 4 on both sides, and the inclined directions of the two axial pushing members 25 are opposite. When the stirring driving mechanism 3 drives the stirring mechanism 2 to rotate, the axial pushing members 25 located on both sides of the discharge device 4 can push the TPV elastomer particles to move in opposite axial directions, so that the TPV elastomer particles on both sides of the chamber 1 flow in the direction of the discharge device 4, which is beneficial to the effective discharge and better emptying of the TPV elastomer particles in the chamber 1.

[0042] In a preferred embodiment, as shown, Figure 4 The discharge device 4 includes a discharge pipe 41, a pipe blocking plate 42, a rotary valve plate 43, and a valve motor 44. One end of the discharge pipe 41 is fixed on the outer side wall of the lower part of the chamber 1, and the lumen is connected to the discharge space inside the chamber 1 through the through hole formed on the side wall of the chamber 1. The other end of the discharge pipe 41 extends obliquely downward, used to guide the TPV elastomer particles discharged from the chamber 1 to the container or packaging bag below the outlet of the discharge pipe 41.

[0043] The pipe blocking plate 42 is arranged in the lumen of the discharge pipe 41, and the discharge pipe 41 is usually arranged in sections, and the pipe blocking plate 42 is fixed at the connection of the two sections of the discharge pipe 41. A semicircular blocking plate hole 421 is arranged at the lower part of the pipe blocking plate 42, so that the TPV elastomer particles in the discharge pipe 41 can flow through the blocking plate hole 421 to the other side of the pipe blocking plate 42, and be discharged from the lumen of the discharge pipe 41.

[0044] The rotary valve plate 43 is arranged on one side of the pipe blocking plate 42 in the lumen of the discharge pipe 41. Specifically, the rotary valve plate 43 is arranged in a circular plate shape, and circular slide rails 437 are arranged on the edge portions on both sides of the rotary valve plate 43. The rotary valve plate 43 is arranged at the connection of the two sections of the discharge pipe 41, located in the gap between the two sections of the discharge pipe 41, and circular slide grooves are arranged on the pipe blocking plate 42 on one side of the rotary valve plate 43, or on the end face of the discharge pipe 41 on that side, and on the end face of the discharge pipe 41 on the other side. The rotary valve plate 43 is rotatably mounted on the discharge pipe 41 by the cooperation of the circular slide rails 437 and the circular slide grooves.

[0045] The valve motor 44 is fixed to the outside of the discharge pipe 41, typically at the connection point of the two discharge pipe sections 41, such that the output shaft of the valve motor 44 is positioned opposite the side edge of the rotary valve plate 43. A drive slot is provided at the connection point of the two discharge pipe sections 41. A helical gear 441 is mounted on the output shaft of the valve motor 44, and valve plate drive teeth 431 are provided on the opposite edge of the rotary valve plate 43. One side of the helical gear 441 passes through the drive slot and meshes with the valve plate drive teeth 431. The rotation of the valve motor 44 drives the rotary valve plate 43 to rotate within the cavity of the discharge pipe 41.

[0046] A semi-circular valve plate hole 432 is provided on the rotary valve plate 43, the size and position of which correspond to the baffle plate hole 421. By rotating the rotary valve plate 43, the valve plate hole 432 and the baffle plate hole 421 can overlap, allowing the cavities of the two discharge pipes 41 to be interconnected, and TPV elastomer particles can be discharged through the discharge pipes 41; or the valve plate hole 432 and the baffle plate hole 421 can be staggered, separating the cavities of the two discharge pipes 41, allowing the TPV elastomer particles to be stored in the chamber 1. The rotation state of the control valve motor 44 can control the storage and discharge of TPV elastomer particles. Controlling the rotation position of the rotary valve plate 43 can also control the size of the overlap area between the valve plate hole 432 and the baffle plate hole 421, thereby controlling the discharge speed of the TPV elastomer particles.

[0047] In a further preferred embodiment, such as Figure 4 and Figure 5 As shown, a bent plate 433 is provided on the edge of the rotary valve plate 43 on one side of the valve plate hole 432, bending away from the pipe baffle plate 42. Multiple anti-pinch flaps 434 are provided on the rotary valve plate 43 adjacent to the bent plate 433. The anti-pinch flaps 434 are L-shaped, including a connecting plate and a flipping plate connected to each other. The end of the connecting plate is rotatably connected to the rotary valve plate 43 via a flipping shaft, and the end of the flipping plate is provided with multiple locking teeth 436. A flap spring 435 is provided between the rotary valve plate 43 and the anti-pinch flaps 434. Under the elastic force of the flap spring 435, the connecting plate of the anti-pinch flap 434 abuts against the bent plate 433, so that the connecting plate is in a position perpendicular to the rotary valve plate 43, while the flipping plate extends out from the edge of the rotary valve plate 43.

[0048] As the valve motor 44 drives the rotating valve plate 43 to rotate, the overlapping area between the valve plate hole 432 and the baffle plate hole 421 gradually decreases. When the edge of the rotating valve plate 43 on the side of the valve plate hole 432 and the edge of the pipe baffle plate 42 on the side of the baffle plate hole 421 gradually approach each other, if any TPV elastomer particles remain between the rotating valve plate 43 and the pipe baffle plate 42, the flip plate will first come into contact with the TPV elastomer particles. The TPV elastomer particles will push the anti-pinch flip plate 434 to flip, causing the edge of the flip plate to move away from the gap between the rotating valve plate 43 and the pipe baffle plate 42. The flip plate will then move away from the gap between the rotating valve plate 43 and the pipe baffle plate 42 through the locking teeth 436, thus preventing the rotating valve plate 43 from rotating further and breaking the TPV elastomer particles between the rotating valve plate 43 and the pipe baffle plate 42.

[0049] An anti-pinch brush 422 is provided on the edge of the pipe baffle 42 on one side of the baffle hole 421. The anti-pinch brush 422 can generate a certain amount of deformation while the anti-pinch flap 434 is flipped by the TPV elastomer particles, so as to prevent the hard edge of the pipe baffle 42 from blocking the TPV elastomer particles from moving with the flipping action of the anti-pinch flap 434.

[0050] In a preferred embodiment, such as Figure 1 As shown, the stirring drive mechanism 3 includes a stirring motor 31 and a reduction gear (not shown in the figure). The stirring motor 31 is fixed on a mounting bracket on one side of the chamber 1. A motor pulley (not shown in the figure) is provided on the output shaft of the stirring motor 31. The motor pulley is connected to the reduction gear via a transmission belt, forming a speed reduction transmission between the two. The reduction gear is connected to a drive wheel (not shown in the figure) on the rotating shaft 21 via another transmission belt, forming a speed reduction transmission between the two. Through the speed reduction transmission on both sides, the rotation speed of the stirring motor 31 can be controlled to effectively slow down the rotation speed of the stirring mechanism 2, forming a stable stirring of the TPV elastomer particles in the chamber 1.

[0051] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
