Description

Technical Field

[0001] The present invention relates to the technical field of recycled polyethylene material production, and specifically to a feeding device for recycled polyethylene material production. Background Art

[0002] Polyethylene (PE), as an important plastic material, is widely used in multiple fields such as packaging, construction, wire and cable, and automobile manufacturing. With the improvement of global environmental awareness and the recycling of resources, the application of recycled polyethylene materials is becoming more and more extensive. However, the production process of recycled polyethylene materials is relatively complex and requires efficient and stable equipment to support. In the production process of recycled polyethylene materials, the feeding device plays a crucial role. It is responsible for transporting the recycled polyethylene materials from the storage or pre-processing position to the designated position on the production line for subsequent processing.

[0003] When the existing equipment feeds recycled polyethylene, the feeding bin continuously transports the recycled polyethylene particles to the surface of the conveyor belt, and the materials on the surface of the conveyor belt will be in a piled-up state. When the conveyor belt carries the materials up for feeding work, the surface of the conveyor belt will be inclined. When the materials are in an inclined state, the materials at the top may fall downward under the influence of gravity, increasing the amount of materials to be transported subsequently. When the subsequent larger amount of materials rises, they will still fall. The continuous falling of the materials may cause the materials to accumulate at the feeding port, resulting in blockage at the accumulation port, affecting the conveying efficiency of the conveyor belt and slowing down the production speed of the production line.

[0004] In view of the above problems, there is an urgent need for innovative design on the original basis. Summary of the Invention

A bidirectional lead screw is installed inside the installation frame through a motor, and the two groups of moving blocks mesh with the bidirectional lead screw.

In the present invention, through the visual detection head, the mobile block, the gear, the rack and the scraper provided, the piled-up materials on the surface of the conveyor belt can be scraped flat, avoiding the phenomenon that the top materials fall when the conveyor belt carries the materials upward. The piled-up materials are evenly spread out, which ensures that when the conveyor belt carries the materials upward, the distribution of the materials is more uniform, reducing the phenomenon of unstable center of gravity or overloading caused by material accumulation. The uniform distribution of the materials can reduce the burden on the conveyor belt and its supporting structure, thereby improving the stability of the entire transmission process; 2. In the present invention, through the mobile adjustment component provided, while the scraper moves and rotates, it can be extended, thereby increasing the area of the scraper for scraping the materials flat, so that the corners of the partitions on the surface of the conveyor belt can also be covered with materials. The increase in the area of the scraper and its flexible extension ability ensure that every corner of the surface of the conveyor belt can be fully scraped flat, especially the hard-to-reach areas such as the corners of the partitions; this avoids the accumulation of materials in these areas; 3. In the present invention, through the provided mobile recovery component, while the scraper levels the material, it will contract upward, causing the scraper to leave the surface of the material. After the scraper levels the material, it contracts and will not continue to apply pressure to the material. This helps to maintain the uniform distribution state of the material, prevent the accumulation or depression of the material caused by the continuous action of the scraper, and according to the quantity of the material, the height of the scraper contraction can be adjusted. When there is more material, the contraction height of the scraper is higher; when there is less material, the contraction height of the scraper is lower, ensuring that the scraper can contract in time after leveling the material.

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-10 , the present invention provides a technical solution: a feeding device for the production of recycled polyethylene materials, including a housing 1. A feeding hopper 4 is installed at the upper right part of the top of the housing 1. A moving table 5 is installed at the left end of the top of the housing 1. An electric push rod A6 is slidably limited inside the moving table 5. An installation frame 7 is installed at the extending end of the electric push rod A6. A moving block 9 is slidably limited inside the installation frame 7. A gear 10 is rotatably connected to the bottom of the moving block 9. A rack 11 is installed at one end of the inner wall of the installation frame 7 away from the feeding hopper 4. A moving recovery component 12 is arranged at the bottom of the gear 10. A connecting block 13 is arranged at the bottom of the moving recovery component 12. A moving adjustment component 14 is arranged at the bottom of the connecting block 13; The moving adjustment component 14 includes an oil tank A141 installed on the inner walls of the front and rear ends of the installation frame 7. A piston rod A142 is slidably limited inside the inner wall of the oil tank A141. It also includes an installation table 143 slidably limited inside the connecting block 13. An oil tank B144 is installed on the side end of the connecting block 13. A piston rod B145 is slidably limited inside the oil tank B144. The end of the piston rod B145 is connected to the side end of the ear seat at the top of the installation table 143. A scraper 15 is installed at the bottom of the installation table 143. The oil tank A141 and the oil tank B144 are connected by a hose. The moving adjustment component 14 can extend while the scraper 15 moves and rotates, thereby increasing the area of the scraper 15 for leveling the material, so that the corners of the partition plates on the surface of the conveyor belt 3 can also be covered with materials. The increase in the area of the scraper 15 and its flexible extension ability ensure that every corner on the surface of the conveyor belt 3 can be fully leveled.

[0020] As an implementation manner of the present invention, a support frame 2 is installed at the bottom end of the housing 1. A conveyor belt 3 is installed inside the housing 1 through a transmission shaft. A number of partition plates are installed on the surface of the conveyor belt 3. The number of partition plates is evenly distributed on the surface of the conveyor belt 3. A visual detection head 8 is installed on one side of the installation frame 7 close to the feeding hopper 4. The installation of a number of partition plates on the surface of the conveyor belt 3 can continuously feed the recycled polyethylene particles. The setting of the visual detection head 8 can synchronously adjust the scraper 15 according to the quantity of the materials; As an embodiment of the present invention, the number of the moving platforms 5 is two groups, and the two groups of moving platforms 5 are symmetrically distributed at the front and rear ends of the top of the housing 1. A lead screw is installed inside the moving platform 5 through a motor, and the bottom protrusion of the electric push rod A6 is engaged with the lead screw inside the moving platform 5. When the transmission belt 3 is in operation, the lead screw is driven to rotate by the motor, so that the mounting frame 7 can move with the same frequency as the transmission belt 3; As an embodiment of the present invention, there are two groups of moving blocks 9 and racks 11, which are symmetrically distributed at the front and rear ends of the mounting frame 7. A bidirectional screw is installed inside the mounting frame 7 through a motor. The two groups of moving blocks 9 are meshed with the bidirectional screw. When the motor drives the bidirectional screw to rotate, the rack 11 drives the gear 10 to rotate, so that the scraper 15 rotates while moving. As an embodiment of the present invention, the scraper 15 is composed of a short plate and a long plate vertically, and the end of the long plate of the scraper 15 is set with an inclined angle. The surface of the long plate of the scraper 15 away from the short plate is smooth. The smooth surfaces of the two groups of scrapers 15 are closely attached to each other, which can prevent the scraper 15 from getting stuck in the gap between the two groups of scrapers 15 when the scraper 15 contacts the material. The opening of the inclined angle at the end of the long plate of the scraper 15 can reduce resistance, making it easier to insert into the accumulated material. As an embodiment of the present invention, the mobile recovery component 12 includes an adjustment bin 121 installed at the bottom of the gear 10, a moving rod 122 is limitedly slidable inside the adjustment bin 121, the bottom of the moving rod 122 is connected to the top of the connecting block 13, a mounting plate 123 is installed at the side end of the adjustment bin 121, a slide 124 is limitedly slidable inside the mounting plate 123, a resistance plate 125 is rotatably connected to one end of the slide 124 near the adjustment bin 121, and an electric push rod B126 is installed at the side end of the slide 124. The extended end of the electric push rod B126 is installed with an extrusion block 127, and the side end of the mounting plate 123 is installed with an electric push rod C128. The extended end of the electric push rod C128 penetrates the mounting plate 123 and is connected to the side end of the slide 124. When the scraper 15 flattens the material, it will shrink upward, so that the scraper 15 leaves the surface of the material. After the scraper 15 flattens the material, it shrinks and will not continue to apply pressure to the material, which helps to maintain a uniform distribution state of the material and prevent the material from piling up or sinking due to the continuous action of the scraper 15. As an embodiment of the present invention, the moving rod 122 is composed of two groups of connecting plates parallel to each other and two groups of round rods perpendicular to the two groups of connecting plates. A protrusion is installed at the bottom of the connecting plate at the upper end of the moving rod 122, and a rounded corner is set at the bottom of the protrusion. The slide 124 is slidably connected inside the moving rod 122. The protrusion at the bottom of the connecting plate at the upper end of the moving rod 122 contacts the upper surface of the slide 124. The design of the protrusion at the bottom of the connecting plate at the upper end of the moving rod 122 can reduce the friction between the moving rod 122 and the contact plate 125. When the material is in an inclined state, the material at the top may fall downward under the influence of gravity. The continuous falling of the material may cause the material to accumulate at the discharge port, resulting in blockage at the accumulation port. The specific implementation method is as follows. First, add recycled polyethylene particles into the feed bin 4. The recycled polyethylene particles fall from the feed bin 4 onto the surface of the conveyor belt 3. The motor drives the transmission shaft to rotate, and the transmission shaft drives the conveyor belt 3 to operate. The scraper 15 is about to contact the piled-up material. The visual detection head 8 will drive the extension end of the electric push rod A6 through the control box to drive the mounting bracket 7 to move downward. The scraper 15 contacts the material. The motor drives the bidirectional screw in the mounting bracket 7 to rotate clockwise. The moving block 9 moves towards both ends in the mounting bracket 7. The movement of the moving block 9 causes the gear 10 to contact the rack 11. The rack 11 drives the gear 10 to rotate. The gear 10 drives the scraper 15 to rotate through the connecting block 13. The movement of the moving block 9 also squeezes the piston rod A142. The oil in the oil tank A141 is injected into the oil tank B144. The oil in the oil tank B144 pushes the piston rod B145 to drive the mounting table 143 to slide in the connecting block 13. The connecting block 13 drives the scraper 15 to extend towards the feed bin 4. The scraper 15 scrapes the piled-up material flat. The conveyor belt 3 continues to operate. The motor drives the screw rod in the moving table 5 to rotate clockwise. The mounting bracket 7 moves synchronously with the conveyor belt 3. While the gear 10 drives the scraper 15 to rotate through the connecting block 13, the control box drives the extension end of the electric push rod C128 to gradually extend. The extension end of the electric push rod C128 drives the sliding table 124 to slide inside the mounting plate 123. The contact plate 125 in the sliding table 124 contacts the convex block at the bottom of the top connecting plate of the moving rod 122. After the gear 10 drives the scraper 15 to rotate 90°, the contact plate 125 completely retracts the moving rod 122 into the adjustment bin 121. When the scraper 15 rotates and moves towards both sides of the conveyor belt 3, it retracts upward away from the material, and the material in the partition of this area of the conveyor belt 3 is scraped flat. The motor drives the screw rod in the moving table 5 to rotate counterclockwise, and the mounting bracket 7 automatically resets. The motor drives the bidirectional screw in the mounting bracket 7 to rotate counterclockwise. The moving block 9 moves towards the middle in the mounting bracket 7. As the moving block 9 moves towards the middle, the gear 10 drives the connecting block 13 to reset. The moving block 9 pulls the piston rod A142, causing the oil in the oil tank B144 to enter the oil tank A141, and the piston rod B145 drives the mounting table 143 to retract and reset; As an implementation manner of the present invention, a spring is sleeved on the round rod surface of the moving rod 122. The top of the spring is connected to the bottom of the adjustment bin 121, and the bottom of the spring is connected to the top of the lower connecting plate of the moving rod 122. The setting of the spring enables the moving rod 122 to automatically reset after losing the pressure of the contact plate 125; As an implementation manner of the present invention, the contact plate 125 and the sliding table 124 are connected by a torsion spring. The surface of the extrusion block 127 is semi-circular. A long block is installed on the surface of the contact plate 125. The control box drives the extending end of the electric push rod B126 to drive the extrusion block 127 to extend. The extrusion block 127 abuts against the back end of the contact plate 125, thereby changing the angle between the contact table and the sliding table 124, and changing the rising height of the scraper 15; Working principle: First, add recycled polyethylene particles into the feeding bin 4. The recycled polyethylene particles fall from the feeding bin 4 onto the surface of the conveyor belt 3. The motor drives the transmission shaft to rotate, and the transmission shaft drives the conveyor belt 3 to operate. When the scraper 15 is about to contact the piled-up material, the visual detection head 8 will drive the extending end of the electric push rod A6 through the control box to drive the mounting frame 7 to move downward. The scraper 15 contacts the material. The motor drives the bidirectional screw in the mounting frame 7 to rotate clockwise, and the moving block 9 moves towards both ends in the mounting frame 7. When the moving block 9 moves, the gear 10 contacts the rack 11, and the rack 11 drives the gear 10 to rotate. The gear 10 drives the scraper 15 to rotate through the connecting block 13. When the moving block 9 moves, it will also squeeze the piston rod A142, and the oil in the oil tank A141 is injected into the oil tank B144. The oil in the oil tank B144 pushes the piston rod B145 to drive the mounting table 143 to slide in the connecting block 13, and the connecting block 13 drives the scraper 15 to extend towards the feeding bin 4. The scraper 15 scrapes the piled-up material flat. The conveyor belt 3 continues to operate. The motor drives the screw in the moving table 5 to rotate clockwise, and the mounting frame 7 moves synchronously with the conveyor belt 3. While the gear 10 drives the scraper 15 to rotate through the connecting block 13, the control box drives the extending end of the electric push rod C128 to gradually extend. The extending end of the electric push rod C128 drives the sliding table 124 to slide inside the mounting plate 123. The contact plate 125 in the sliding table 124 contacts the convex block at the bottom of the connecting plate at the top of the moving rod 122. After the gear 10 drives the scraper 15 to rotate 90°, the contact plate 125 completely retracts the moving rod 122 into the adjustment bin 121. When the scraper 15 rotates and moves towards both sides of the conveyor belt 3, it retracts upward away from the material, and the material in the partition of this area of the conveyor belt 3 is scraped flat. The motor drives the screw in the moving table 5 to rotate counterclockwise, and the mounting frame 7 automatically resets. The motor drives the bidirectional screw in the mounting frame 7 to rotate counterclockwise, and the moving block 9 moves towards the middle in the mounting frame 7. When the moving block 9 moves towards the middle, the gear 10 drives the connecting block 13 to reset, and the moving block 9 pulls the piston rod A142, so that the oil in the oil tank B144 enters the oil tank A141, and the piston rod B145 drives the mounting table 143 to retract and reset; When the visual detection head 8 detects a large quantity of materials, the control box drives the extending end of the electric push rod B126 to drive the extrusion block 127 to extend. The extrusion block 127 abuts against the back end of the abutting plate 125, and the angle between the abutting plate 125 and the sliding table 124 becomes larger. The extending end of the electric push rod C128 pushes the sliding table 124 to move, and the rising height of the scraping plate 15 will increase. When the visual detection head 8 detects a small quantity of materials, the control box drives the extending end of the electric push rod B126 to drive the extrusion block 127 to contract. The contact area between the abutting plate 125 and the extrusion block 127 changes, and the abutting plate 125 is rebounded by the torsion spring. The angle between the abutting plate 125 and the sliding table 124 becomes smaller. The extending end of the electric push rod C128 pushes the sliding table 124 to move, and the rising height of the scraping plate 15 will decrease.
