Description

Technical Field

[0001] This invention relates to the field of conveying equipment technology, and specifically to an automated material conveying device for the production of polyurethane plastic track synthetic materials. Background Technology

[0002] Plastic running track materials are composed of polyurethane prepolymer, mixed polyether, waste tire rubber, EPDM rubber granules or PU granules, pigments, additives, and fillers. Plastic running tracks possess characteristics such as good flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties, which are beneficial to athletes' speed and technique, effectively improving athletic performance and reducing the rate of falls and injuries. Tubular chain conveyors are continuous conveying equipment for transporting powdery, granular, and lumpy bulk materials. They can transport materials horizontally, inclined, and vertically in combination, and are generally used in fine chemicals, pesticides and ores, building materials, and food industries. In the production process of synthetic plastic running track materials, material transport is required through conveying devices, and tubular chain conveyors are commonly used conveying devices in the production of synthetic plastic running track materials.

[0003] Chinese patent document CN218057088U discloses a material conveying device for the production of synthetic materials for plastic running tracks. The device includes a first housing, a lifting device, a screening device, an inclined plate, a second housing, a first feed hopper, a second feed hopper, two sets of rollers, a first motor, and two sets of gears. The first housing has a first discharge port on its left end and a second discharge port on its right end. The lifting device is connected to the second discharge port of the first housing and is used for conveying materials. The inclined plate is installed at the bottom of the inner wall of the first housing. The screening device is installed inside the first housing and is used for screening materials. The second housing is connected to the top of the first housing. The first feed hopper is connected to the lower part of the outer wall of the second housing, and the second feed hopper is connected to the top of the second housing. The front and rear ends of the two sets of rollers are rotatably mounted on the inner wall of the second housing. The first motor is mounted on the front wall of the second housing, and its output end is concentrically connected to the front end of one set of rollers. The two sets of gears are concentrically mounted at the rear ends of the two sets of rollers and mesh with each other.

[0004] During operation, the material to be conveyed is first fed into the second housing through the first feed hopper. The material then enters the first housing and falls to the top of the second bottom plate. The material is screened and filtered through the screen on the second bottom plate, so that large particles are conveyed through the second bottom plate to the first discharge port of the first housing, while small particles pass through the screen and fall to the top of the inclined plate. The inclined plate then conveys the material into the housing through the flexible connecting pipe. The material inside the housing falls to the top of the electric conveyor belt. The electric conveyor belt rotates and lifts the material to the upper right. By adjusting the extension and retraction length of the moving end of the hydraulic cylinder, the slider can be adjusted to slide left and right. The slider is supported by the bracket on the right side of the bottom of the housing, causing the housing to drive the right side of the electric conveyor belt to swing up and down, thus lifting and conveying the material to different heights.

[0005] In the above technology, after the material is conveyed to different heights by the electric conveyor belt, when it is unloaded, the conveying device has difficulty buffering the impact force of the falling material as it falls from the top of the electric conveyor belt, resulting in a large amount of dust being generated when the material falls. Summary of the Invention

[0006] This invention provides an automated material conveying device for the production of polyurethane plastic running track synthetic materials. It aims to solve the technical problem in the prior art where, after materials are conveyed to different heights by an electric conveyor belt, the conveying device is unable to buffer the impact force of the falling materials during unloading, resulting in a large amount of dust being generated when the materials fall.

[0007] The present invention discloses an automated material conveying device for the production of polyurethane plastic running track synthetic materials, comprising a conveying mechanism, the conveying mechanism comprising a conveying pipe, a drive component disposed on the conveying pipe for conveying materials in the conveying pipe, a feed hopper and a discharge hopper disposed in the conveying pipe, the discharge hopper being provided with a telescopic material cylinder, the telescopic material cylinder comprising a dustproof component and multiple sets of material dropping components, each of the material dropping components being spaced apart from top to bottom inside the dustproof component; The material feeding assembly includes a connector and at least two buffers. The connector is annular, and the upper end of the buffer is elastically connected to the connector. The buffer is inclined from top to bottom towards the axial direction of the connector, and any two adjacent connectors are elastically connected. The dustproof component includes a cover and multiple connecting parts. The connecting parts are annular, and each connecting part is longitudinally spaced and fixed relative to the cover. The connecting part located at the bottommost side is fixed relative to the connecting part at the bottommost side.

[0008] The beneficial effects are: ensuring the uniformity of wear on each buffer component during use, extending the service life of the telescopic material cylinder, during the material feeding process through the telescopic material cylinder, the material contacts the buffer component and generates an impact force on the buffer component, the impact component rotates relative to the connecting component under the impact of the material, buffering the falling material, the impact force on the buffer component in the circumferential direction is basically uniform, reducing the problem of uneven wear on a single position when the buffer component buffers the material; The two adjacent sets of material feeding components are elastically connected to avoid the situation where two or more adjacent material feeding components overlap during the extension process due to excessive tightness, which would prevent the material from being buffered. This ensures the effectiveness of the buffering work of each set of material feeding components, so that the material is fully buffered when falling, reducing the dust generated by the falling powder material, and extending the overall service life of the telescopic cylinder. At the same time, it can also effectively reduce the frequency of maintenance and downtime during unloading, and ensure work efficiency.

[0009] Preferably, the buffer member is further provided with an anti-clogging structure, which includes a movable block, a connecting block, and a pull rope. The buffer member has a notch, the shape of the movable block matches the notch, the upper end of the movable block is elastically connected to the notch, the connecting block is fixed to the buffer member from the notch, one end of the pull rope passes around the connecting block and is fixed to the movable block, and the other end of the pull rope is fixed to the upper connecting member or the feed end of the telescopic cylinder.

[0010] Preferably, with the side facing the axial direction of the feeding assembly as the inner side, a protrusion is provided on the inner sidewall of the movable block, and the protrusion is inclined downward in a direction away from the movable block.

[0011] The beneficial effects are as follows: It ensures the automatic discharge of materials in the telescopic material cylinder. When the material is blocked in a certain material discharge component, it will exert a large downward pulling force on the elastic element, causing the material discharge component with accumulated material to move down. The distance between two adjacent sets of material discharge components exceeds the deformation range of the elastic element during buffering. The pull rope adapts to the change in the distance between the two sets of material discharge components and pulls the movable block to slide down relative to the buffer element. When the movable block slides, it moves the material accumulated in the material discharge component through the protrusion on it, promoting the reflow of the accumulated material and automatically clearing the material blockage in the material discharge component.

[0012] Preferably, the buffers of adjacent feeding assemblies are staggered in the circumferential direction.

[0013] The beneficial effects are: it enhances the buffering effect of the buffer components on the material. The buffer components on adjacent feeding assemblies are staggered in the circumferential direction. That is, when the material passes through two adjacent feeding assemblies, the buffer components on these two sets of feeding assemblies rotate in different directions relative to the connecting parts when they are impacted by the material, thus improving the buffering effect on the material.

[0014] Preferably, the telescopic cylinder is further provided with a winding assembly, which includes a winding machine and a winding rope. One end of the winding rope is fixed relative to the lowermost connecting part, and the other end of the winding rope is fixed to the winding machine.

[0015] Preferably, adjacent connectors are connected by a guide rod, which restricts relative rotation of adjacent connectors in their axial direction.

[0016] The beneficial effects are: to prevent the elastic element from twisting due to horizontal forces during the material dropping and folding operations of the telescopic cylinder, thus ensuring the normal use of the elastic element.

[0017] Preferably, there are multiple guide rods, each guide rod is connected to three adjacent connectors, and each connector is connected to only one guide rod.

[0018] The beneficial effect is that each set of material feeding components is connected by multiple guide rods, which avoids the setting of the guide rods affecting the folding operation of the telescopic cylinder.

[0019] Preferably, two adjacent connectors are connected by at least two elastic elements, and each elastic element is evenly arranged along the circumference of the connector.

[0020] Preferably, a set of the feeding assembly includes two buffers, which are combined into a conical shape.

[0021] Preferably, the drive assembly includes a chain link disposed within the conveying pipe and a drive component for driving the chain link to move.

[0022] The beneficial effects of this invention are as follows: 1. In this invention, the uniformity of wear on each buffer component during use is ensured, and the service life of the telescopic material cylinder is extended. During the process of material being fed through the telescopic material cylinder, it comes into contact with the buffer component and generates an impact force on the buffer component. The impact component rotates relative to the connecting component under the impact of the material, thus buffering the falling material. The impact force on the buffer component in the circumferential direction is basically consistent, reducing the problem of uneven wear on a single position when the buffer component buffers the material. The two adjacent sets of material feeding components are elastically connected to avoid the situation where two or more adjacent material feeding components overlap during the extension process due to excessive tightness, which would prevent the material from being buffered. This ensures the effectiveness of the buffering work of each set of material feeding components, so that the material is fully buffered when falling, reducing the dust generated by the falling powder material, extending the overall service life of the telescopic cylinder, and also effectively reducing the frequency of maintenance and downtime during unloading, thus ensuring work efficiency.

[0023] 2. In this invention, the material is automatically discharged into the telescopic material cylinder. When the material is blocked in a certain discharge component, it will exert a large downward pulling force on the elastic element, causing the discharge component with the accumulated material to move downward. The distance between two adjacent sets of discharge components exceeds the deformation range of the elastic element during buffering. The pull rope adapts to the change in the distance between the two sets of discharge components and pulls the movable block to slide downward relative to the buffer element. When the movable block slides, it moves the material accumulated in the discharge component through the protrusion on it, promoting the reflow of the accumulated material and automatically clearing the blockage in the discharge component.

Detailed Implementation

[0031] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0032] Reference Figures 1-6An automated material conveying device for the production of polyurethane plastic running track synthetic materials according to the present invention includes a frame and a conveying mechanism 1 disposed on the frame. The conveying mechanism 1 is used to convey materials. The conveying mechanism 1 includes a conveying pipe 11 disposed on the frame, a drive assembly 12 disposed on the conveying pipe 11 and used to convey materials in the conveying pipe 11, a feed hopper 13 disposed in the conveying pipe 11 and a discharge hopper 14 disposed in the conveying pipe 11. The conveying pipe 11 is configured as a closed pipe. The feed hopper 13 is located at the bottom end of the conveying pipe 11 and is connected to the conveying pipe 11. The discharge hopper 14 is located at the top end of the conveying pipe 11. A telescopic material cylinder is disposed on the discharge hopper 14 and is used to unload materials in the discharge hopper 14. When materials need to be conveyed, the materials are first added to the feed hopper 13, and then the drive assembly 12 is started. After the materials in the feed hopper 13 enter the conveying pipe 11, the drive assembly 12 can drive the materials to move and convey the materials to the discharge hopper 14. After the materials reach the discharge hopper 14, they are unloaded through the telescopic material cylinder. In this way, the materials are circulated and conveyed to complete the material conveying operation.

[0033] The discharge hopper 14 is equipped with an electrostatic eliminator 4 for eliminating static electricity in the material. After the material reaches the discharge hopper 14, it enters the telescopic cylinder after being eliminated by the electrostatic eliminator 4. The drive assembly 12 includes multiple chain pieces disposed in the conveying pipe 11 and a drive component 121 for driving the chain pieces to move. The multiple chain pieces are evenly spaced along the conveying pipe 11. The drive component 121 includes a chain (not shown in the figure) for driving the chain pieces to move, a sprocket (not shown in the figure) for driving the chain to rotate, and a motor for driving the sprocket to rotate. The sprocket meshes with the chain. The motor drives the sprocket to rotate through a reduction gearbox. When the motor is started, it drives the sprocket to rotate through the reduction gearbox, which in turn drives the chain to rotate. The chain drives the chain pieces to rotate and pushes the material in the storage cavity formed between two adjacent chain pieces and the conveying pipe 11, thereby conveying the material.

[0034] The telescopic material cylinder includes a dustproof component and multiple sets of material dropping components. The dustproof component covers the outside of each set of material dropping components, and each set of material dropping components is longitudinally spaced inside the dustproof component. The dustproof component includes a cover cloth 2 and multiple connecting parts 21. The connecting parts 21 are annular, and each connecting part 21 is longitudinally spaced and fixed relative to the cover cloth 2. The material feeding assembly includes a connector 3 and at least two buffers 31. The connector 3 is ring-shaped, and the upper end of the buffer 31 is elastically connected to the connector 3. When the material falls to contact the buffer 31, it generates an impact force on the buffer 31. Under the impact of the material, the buffer 31 rotates relative to the connector 3 and buffers the falling material, reducing the falling speed of the material and reducing the dust generated by the falling material. Any two adjacent connectors 3 are connected by an elastic member 32. The connector 3 located at the bottom is fixed relative to the bottom connecting part 21 so that each set of material feeding assemblies can extend and retract synchronously with the dustproof part.

[0035] The buffer element 31 can be connected to the connecting element 3 via a torsion spring. The buffer element 31 is inclined from top to bottom towards the axial direction of the connecting element 3. The buffer elements 31 of the same feeding assembly close together under the force of the torsion spring and form a conical cylinder with a diameter decreasing from top to bottom. Preferably, a set of feeding assemblies is provided with two buffer elements 31. When the material is fed through the telescopic feeding cylinder, it falls on the buffer element 31 and generates an impact force on the buffer element 31. The buffer element 31 rotates relative to the connecting element 3 under the impact of the material. When the material falls on the buffer element 31, each buffer element 31 moves away from the axial direction of the connecting element 3 and squeezes the torsion spring to store force. The impact force on the buffer element 31 in the circumferential direction is basically the same, which reduces the problem of uneven wear of a single position when the buffer element 31 is buffered by the material, and improves the service life of the buffer element 31.

[0036] To further enhance the buffering effect of the buffer 31 on the material, the buffers 31 on adjacent feeding assemblies are staggered in the circumferential direction. That is, when the material passes through two adjacent feeding assemblies, the buffers 31 on these two sets of feeding assemblies rotate in different directions relative to the connecting member 3 when they are impacted by the material.

[0037] To enable the telescopic material cylinder to extend and retract, a winding assembly is also provided on the frame. The winding assembly includes a winding machine (not shown in the figure) and a winding rope 22. One end of the winding rope 22 is connected to the winding machine, and the other end of the winding rope 22 is fixed to the bottommost connecting part 21. When the winding machine winds the winding rope 22, it pulls the connecting part 21 upward and folds the dustproof part. When the connecting part 21 moves upward, it drives each material dropping assembly to move from bottom to top and overlap, thereby realizing the folding operation of the telescopic material cylinder. In order to make the force on the telescopic material cylinder relatively balanced when it extends and retracts, two sets of winding assemblies can be set, and the two sets of winding assemblies are symmetrically arranged about the axis of the telescopic material cylinder.

[0038] Two adjacent sets of material feeding components are elastically connected by elastic elements 32. When the telescopic material cylinder is folded, the elastic elements 32 used to connect the two connecting parts 3 are in a compressed and stored state, which facilitates the rapid pushing of adjacent material feeding components away from each other when the telescopic material cylinder extends. This avoids the situation where two or more adjacent material feeding components overlap during the extension process due to excessively tight stacking, which would prevent the material from being buffered. This ensures the effectiveness of the buffering work of each set of material feeding components, and allows the buffer elements 31 of each set of material feeding components to be fully utilized. During the material feeding process, the wear of each buffer element 31 in the telescopic material cylinder is relatively uniform, which extends the overall service life of the telescopic material cylinder and can also effectively reduce the frequency of maintenance and downtime during operation, thus ensuring work efficiency.

[0039] When the conveying device loads powdery bulk materials, there may be a problem of material clogging the material discharge component, affecting the normal material discharge. To solve this problem, the buffer 31 is also equipped with an anti-clogging structure, which includes a movable block 34, a connecting block 36, and a pull rope 35. The buffer 31 has a notch, and the shape of the movable block 34 matches the shape of the notch. The movable block 34 is slidably connected to the notch, and the upper end of the movable block 34 is elastically connected to the notch. The connecting block 36 is fixed to the buffer 31 from the notch. One end of the pull rope 35 passes around the connecting block 36 and is fixed to the movable block 34. The other end of the pull rope 35 is fixed to the feed end of the upper connecting part 3 or the telescopic material cylinder. With the side facing the axial direction of the material discharge component as the inner side, the inner side wall of the movable block 34 is provided with a protrusion 341. The protrusion 341 is inclined downward in the direction away from the movable block 34.

[0040] When the material falls normally through each feeding assembly, the longitudinal force exerted by the impact buffer 31 on the elastic member 32 on its upper side is relatively small. When the material is blocked in a certain feeding assembly, it will exert a large downward pulling force on the elastic member 32, causing the feeding assembly with the accumulated material to move downward. The distance between two adjacent feeding assemblies exceeds the deformation range of the elastic member 32 during buffering. The pull rope 35 adapts to the change in the distance between the two feeding assemblies and pulls the movable block 34 to slide downward relative to the buffer 31. When the movable block 34 slides, it moves the material accumulated in the feeding assembly through the protrusion 341 on it, promoting the reflow of the accumulated material, so as to automatically clear the blockage caused by the material in the feeding assembly and ensure the automatic feeding of the material in the telescopic cylinder.

[0041] Two adjacent connecting parts 3 are connected by at least two elastic elements 32. Each elastic element 32 is evenly distributed along the circumference of the connecting part 3. The elastic element 32 can be a spring. To prevent the elastic element 32 from twisting due to horizontal forces during the material dropping and folding operations of the telescopic cylinder, ensuring its normal operation, adjacent connecting parts 3 are connected by guide rods 33. To prevent the guide rods 33 from affecting the folding of the telescopic cylinder, the guide rods 33 restrict the relative rotation of adjacent connecting parts 3 in their axial direction. There are multiple guide rods 33, with each guide rod 33 connected to three adjacent connecting parts 3, and each connecting part 3 connected to only one guide rod 33. This arrangement of the guide rods 33 prevents the folding operation of the telescopic cylinder from being affected.

[0042] The automated material conveying device for the production of polyurethane plastic running track synthetic materials provided by this invention is mainly used for unloading and transferring powdery bulk materials. In other embodiments, it can also be used to convey and unload granular or small block materials (such as grain and coal) as needed. When unloading granular or block materials, it can also fully buffer the materials during the falling process and reduce the breakage and dust generation of materials during the unloading process.

[0043] The automated material conveying device for the production of polyurethane plastic track synthetic materials provided by this invention is used to fully buffer the material during unloading, reduce dust during the material dropping process, improve the consistency of wear of each buffer component 31 in the telescopic material cylinder during use, extend the service life of the telescopic material cylinder, and at the same time ensure the loading efficiency of the material.
