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 many 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

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention, through the provision of a visual inspection head, a moving block, a gear, a rack, and a scraper, can scrape off the accumulated materials on the surface of the transmission belt, preventing the materials from falling off the top of the transmission belt when the transmission belt is carrying the materials upward. The accumulated materials are evenly spread out, which ensures that the materials are distributed more evenly when the transmission belt is carrying the materials upward, reducing the unstable center of gravity or overload caused by the accumulation of materials. The even distribution of materials can reduce the burden on the transmission belt and its supporting structure, thereby improving the stability of the entire transmission process.

[0018] 2. The present invention provides a movable adjustment assembly, which allows the scraper to extend while it moves and rotates, thereby increasing the scraper's scraping area for the material, so that even the corners of the partitions on the belt surface can be covered with material. The increased scraper area and flexible extension capability ensure that every corner of the belt surface can be fully scraped and leveled, especially hard-to-reach areas such as the partition corners; this prevents material from accumulating in these areas.

[0019] 3. In the present invention, through the arranged 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.

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] 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 bin 4 is installed at a position near the right end of the top of the housing 1. A moving table 5 is installed at a position on the left end of the top of the housing 1. An electric push rod A6 is slidably limited inside the moving table 5. The extending end of the electric push rod A6 is installed with a mounting frame 7. A moving block 9 is slidably limited inside the mounting frame 7. The bottom of the moving block 9 is rotatably connected with a gear 10. A rack 11 is installed at one end of the inner wall of the mounting frame 7 away from the feeding bin 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;

[0033] The moving adjustment component 14 includes an oil tank A141 installed on the inner walls of the front and rear ends of the mounting frame 7. A piston rod A142 is slidably limited inside the inner wall of the oil tank A141. It also includes a mounting 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 mounting table 143. A scraper 15 is installed at the bottom of the mounting table 143. The oil tank A141 and the oil tank B144 are connected with 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 transmission 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 transmission belt 3 can be fully leveled.

[0034] As an implementation manner of the present invention, a support frame 2 is installed at the bottom end of the housing 1. A transmission belt 3 is installed inside the housing 1 through a transmission shaft. A plurality of partition plates are installed on the surface of the transmission belt 3, and the plurality of partition plates are evenly distributed on the surface of the transmission belt 3. A vision detection head 8 is installed on the installation frame 7 close to the feeding bin 4. The installation of the plurality of partition plates on the surface of the transmission belt 3 can continuously feed the recycled polyethylene particles. The setting of the vision detection head 8 can synchronously adjust the scraper 15 according to the quantity of the materials;

[0035] As an implementation manner 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. The convex block at the bottom of the electric push rod A6 is engaged with the lead screw inside the moving platform 5. When the transmission belt 3 operates, the lead screw is driven to rotate by the motor, so that the installation frame 7 can move synchronously with the transmission belt 3;

[0036] As an implementation manner of the present invention, the number of the moving blocks 9 and the racks 11 is two groups, and the two groups of moving blocks 9 and the racks 11 are symmetrically distributed at the front and rear ends inside the installation frame 7. A bidirectional screw is installed inside the installation frame 7 through a motor. The two groups of moving blocks 9 are engaged with the bidirectional screw. When the bidirectional screw is driven to rotate by the motor, the rack 11 drives the gear 10 to rotate, so that the scraper 15 rotates while moving;

[0037] As an implementation manner of the present invention, the scraper 15 is composed of a short plate and a long plate perpendicular to each other. An inclined angle is provided at the end of the long plate of the scraper 15. 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 materials from getting stuck in the gap between the two groups of scrapers 15 when the scraper 15 contacts the materials. The opening of the inclined angle at the end of the long plate of the scraper 15 can reduce the resistance and make it easier to insert into the piled materials;

[0038] As an implementation manner of the present invention, the mobile recovery component 12 includes an adjustment bin 121 installed at the bottom of the gear 10. A movable rod 122 is limited and slid inside the adjustment bin 121. The bottom of the movable rod 122 is connected to the top end of the connection block 13. An installation plate 123 is installed at the side end of the adjustment bin 121. A slide table 124 is limited and slid inside the installation plate 123. One end of the slide table 124 close to the adjustment bin 121 is rotatably connected with a contact plate 125. An electric push rod B 126 is installed at the side end of the slide table 124. An extrusion block 127 is installed at the extending end of the electric push rod B 126. An electric push rod C 128 is installed at the side end of the installation plate 123. The extending end of the electric push rod C 128 penetrates through the installation plate 123 and is connected to the side end of the slide table 124. While the scraper 15 levels the material, it will contract upward, causing the scraper 15 to leave the surface of the material. After the scraper 15 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 and prevent material accumulation or depression caused by the continuous action of the scraper 15;

[0039] As an implementation manner of the present invention, the movable rod 122 is composed of two groups of connecting plates parallel up and down and two groups of round rods perpendicular to the two groups of connecting plates. A convex block is installed at the bottom of the upper connecting plate of the movable rod 122. A fillet is provided at the bottom of the convex block. The slide table 124 is slidably connected inside the movable rod 122. The convex block at the bottom of the upper connecting plate of the movable rod 122 abuts against the upper surface of the slide table 124. The design of the convex block at the bottom of the upper connecting plate of the movable rod 122 can reduce the friction between the movable rod 122 and the contact plate 125;

[0040] 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 accumulated material. The visual detection head 8 will drive the extending end of the electric push rod A6 to drive the mounting frame 7 to move downward through the control box. The scraper 15 contacts the material. The motor drives the bidirectional screw in the mounting frame 7 to rotate clockwise. The moving block 9 moves towards both ends in the mounting frame 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 1 3. The movement of the moving block 9 will also squeeze 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 accumulated material to be flat. The conveyor belt 3 continues to operate. The motor drives the screw rod in the moving table 5 to rotate clockwise. 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 in 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 shrinks upward and leaves the material. The material in the partition of this area of the conveyor belt 3 is scraped to be flat. The motor drives the screw rod 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. 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. The moving block 9 pulls the piston rod A142, so that the oil in the oil tank B144 enters the oil tank A141. The piston rod B145 drives the mounting table 143 to retract and reset;

[0041] 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;

[0042] As an implementation manner of the present invention, a torsion spring is used to connect the contact plate 125 and the sliding table 124. The surface of the extrusion block 127 is semi-circular. A long block is installed on the surface of the contact plate 125. By driving the extending end of the electric push rod B126 through the control box, the extrusion block 127 is driven 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 height at which the scraping plate 15 rises;

[0043] Working principle: First, add the 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 scraping plate 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 rack 7 to move downward. The scraping plate 15 contacts the material. The motor drives the bidirectional screw in the mounting rack 7 to rotate clockwise, and the moving block 9 moves towards both ends in the mounting rack 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 scraping plate 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 scraping plate 15 to extend towards the feeding bin 4. The scraping plate 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, and the mounting rack 7 moves synchronously with the conveyor belt 3. While the gear 10 drives the scraping plate 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 scraping plate 15 to rotate 90°, the contact plate 125 completely retracts the moving rod 122 into the adjustment bin 121. When the scraping plate 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 rack 7 automatically resets. The motor drives the bidirectional screw in the mounting rack 7 to rotate counterclockwise, and the moving block 9 moves towards the middle in the mounting rack 7. When the moving block 9 moves towards the middle, the gear 10 will drive the connecting block 13 to reset, and the moving block 9 will pull 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;

[0044] 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.
