Description

Technical Field

[0001] This utility model relates to the field of lifting device technology, specifically to a lifting device for raw materials of MPP / PE cable protection pipes. Background Technology

[0002] MPP / PE cable protection pipes are two types of buried pipes made of polymer materials as the base material, specifically designed to protect underground cables. They are used to isolate the cables from soil corrosion, mechanical impact, and groundwater erosion, preventing cable damage. They are widely used in municipal engineering and other scenarios. In the production process of cable protection pipes, the main processes include raw material processing, extrusion molding, cooling, and traction cutting. In the raw material pretreatment stage, various granular raw materials need to be mixed and then lifted by a lifting device and transported to the storage bin of the extruder for the extruder to extrude the cable. Usually, a auger elevator is used to lift the raw materials. The motor drives the spiral blades (auger) to rotate, and the axial thrust generated by the blades is used to continuously and smoothly transport the material upward along the sealed shell. At the bottom of the sealed shell, there is usually a feed hopper. By pouring raw materials into the feed hopper, the raw materials enter the sealed shell and are then transported upward by the auger. However, during the feeding process, because the feed hopper is full of raw materials, when various raw materials are transferred from the feed hopper to the auger, a large amount of raw materials directly rush into the bottom of the sealed shell, which can easily lead to the accumulation and blockage of raw materials in the auger. Utility Model Content

[0003] To overcome the above-mentioned defects, the present invention provides a raw material lifting device for MPP / PE cable protection pipes, which solves the technical problem in the prior art where a large amount of raw material directly flows into the bottom of the sealed shell during the feeding process, which easily leads to the accumulation and blockage of raw material in the auger.

[0004] According to one aspect, at least one embodiment of the present invention provides a raw material lifting device for MPP / PE cable protection pipes, including a winch elevator. The winch elevator includes a sealed housing, the bottom end of which is connected to a feed hopper. It also includes a partition plate, a rotating shaft, a baffle plate, a fixed plate, and an extrusion mechanism, which are fixedly arranged inside the feed hopper and form a feeding space with the feed hopper. A plurality of rotating shafts are rotatably arranged on the inner wall of the feed hopper. A rotating roller is coaxially fitted on the rotating shaft and fixedly connected to the rotating roller. One end of the baffle plate is provided with an arc-shaped end face and slides in cooperation with the partition plate. The plurality of baffle plates divide the feeding space into a plurality of storage cavities, which are arranged on the rotating shaft through elastic connecting members and are provided with arc surfaces. A limiting groove that cooperates with the fixed plate is opened in the feed hopper. The extrusion mechanism is arranged on the feed hopper and is used to sequentially drive the plurality of fixed plates out of the limiting groove and feed material into the sealed housing at intervals.

[0005] Preferably, the elastic connector includes a limiting plate and a connecting spring. The limiting plate is fixedly connected to both ends of the fixing plate. A snap-fit ​​groove that cooperates with the limiting plate is opened in the rotating shaft. A slot is opened in the rotating shaft. The two ends of the connecting spring are fixedly connected to the inner wall of the slot and the fixing plate, respectively.

[0006] Furthermore, the extrusion mechanism includes an extrusion plate, a connecting plate, and an electric cylinder. The extrusion plate is slidably disposed in the limiting groove, and one end is provided with an arc extrusion head that mates with the arc surface. The feed hopper is provided with a through groove that mates with the connecting plate. The connecting plate is slidably disposed with the inner wall of the through groove and one end is fixedly connected to the extrusion plate. The electric cylinder is mounted on the feed hopper, and its output end is fixedly connected to the connecting plate.

[0007] Furthermore, one end of the rotating shaft is provided with a contact plane that cooperates with the extrusion plate, which is used to drive the entire arc surface into the slot.

[0008] As a further embodiment of this application, a rocker arm is coaxially fixed at the other end of the rotating shaft to drive the rotating shaft to rotate so that the slot connects with the limiting slide groove.

[0009] As a further embodiment of this application, the arc-shaped extrusion head on the extrusion plate faces the opening of the feed hopper, so that after the material storage chamber is filled with raw materials, the rotating shaft close to the sealing shell is rotated first.

[0010] Based on the aforementioned scheme, the partition plate is provided with a feed inlet that communicates with the storage cavity located in the middle of the feeding space.

[0011] Furthermore, based on the aforementioned scheme, the feed hopper is provided with an abutment groove that cooperates with the baffle plate to support the baffle plate.

[0012] The beneficial effects of this utility model are as follows: In this utility model, through the cooperation of the feeding hopper, partition plate, rotating shaft, baffle plate, fixed plate, elastic connector and extrusion mechanism, when the fixed plate is engaged in the limiting slide groove, the material is fed into multiple storage bins, and the multiple storage bins can divide the raw material in the feeding space into multiple small portions. By starting the electric cylinder to drive the arc extrusion head to push multiple fixed plates into the slot in sequence, the rotating shaft and baffle plate connected to the fixed plate will rotate under the action of the gravity of the raw material. The raw material is fed into the sealed shell in a sequential and intermittent manner, which can avoid the blockage in the auger. By rotating the rocker arm in conjunction with the electric cylinder to drive the extrusion plate to move, the rotating shaft rotates and the fixed plate is re-inserted into the limiting slide groove under the elastic force of the connecting spring. This causes multiple baffle plates to divide the feeding space into multiple storage bins again, and causes the arc extrusion head on the extrusion plate to face multiple arc surfaces again, which is convenient for the next interval feeding.

[0021] like Figures 1-5As shown, it illustrates an embodiment of the present invention of an MPP / PE cable protection pipe raw material lifting device, including a auger elevator 1. The auger elevator 1 includes a sealed housing 2, the bottom end of which is connected to a feed hopper 3. Spiral blades (augers) are provided inside the sealed housing 2. After the raw material is poured into the feed hopper 3, the raw material at the bottom end of the sealed housing 2 is driven to be lifted upward by the rotation of the auger. It also includes a partition plate 4, a rotating shaft 25, a baffle plate 7, a fixing plate 9, and an extrusion mechanism. like Figure 2 As shown, the partition plate 4 is fixedly installed inside the feed hopper 3 and forms a feeding space 5 with the feed hopper 3. Multiple rotating shafts 25 are rotatably installed on the inner wall of the feed hopper 3. Rotating rollers 6 are coaxially mounted on the rotating shafts 25. The baffle plate 7 is fixedly connected to the rotating rollers 6. One end of the baffle plate 7 is provided with an arc-shaped end face and slides in cooperation with the partition plate 4. One end of the baffle plate 7 is in contact with the partition plate 4 and slides in cooperation. Multiple baffle plates 7 divide the feeding space 5 into multiple storage cavities 8. The partition plate 4 is provided with a feed port 23 that communicates with the storage cavity 8 located in the middle of the feeding space 5. The feed port 23 is located diagonally above (at a high position) the corresponding storage cavity 8. like Figure 5 As shown, the fixed plate 9 is mounted on the rotating shaft 25 via an elastic connector and has an arc surface 10. The feed hopper 3 has a limiting groove 11 that mates with the fixed plate 9. The elastic connector includes a limiting plate 12 and a connecting spring 14. Both ends of the fixed plate 9 are fixedly connected to the limiting plate 12. The rotating shaft 25 has a snap-fit ​​groove 13 that mates with the limiting plate 12. A slot 15 is also formed inside the rotating shaft 25. Both ends of the connecting spring 14 are fixedly connected to the inner wall of the slot 15 and the fixed plate 9, respectively. 4 When not compressed, the connecting spring 14 drives the arc surface 10 of the fixing plate 9 to be in the limiting slide groove 11, so that the fixing plate 9 is locked in the limiting slide groove 11, making it difficult for the rotating shaft 25 to rotate. At this time, the rotating shaft 25 is in a state perpendicular to the feeding space 5, and forms a storage bin with the baffle plate 7 on one side and the feeding space 5. Material can be discharged into the storage bin through the feed port 23. Multiple storage bins can divide the raw material in the feeding space 5 into multiple small portions. By discharging the material in sequence at intervals, blockage in the auger can be avoided. like Figures 2-4As shown, the extrusion mechanism is installed on the feed hopper 3, used to sequentially move multiple fixed plates 9 out of the limiting slide groove 11 and feed material into the sealing housing 2 at intervals. The extrusion mechanism includes an extrusion plate 16, a connecting plate 18, and an electric cylinder 20. The extrusion plate 16 is slidably installed in the limiting slide groove 11, and one end is provided with an arc extrusion head 17 that cooperates with the arc surface 10. The arc extrusion head 17 and the arc surface 10 have the same radius. The arc extrusion head 17 on the extrusion plate 16 faces the opening of the feed hopper 3. After the material storage chamber 8 is filled with raw materials, the rotating shaft 25 close to the sealing housing 2 is rotated first. One end of the rotating shaft 25 is provided with a contact plane 21 that cooperates with the extrusion plate 16, used to drive the arc surface 10 to fully enter the slot 15. The feed hopper 3 is provided with a through groove 19 that cooperates with the connecting plate 18. The connecting plate 18 is slidably engaged with the inner wall of the through groove 19 and one end is fixedly connected to the extrusion plate 16. The electric cylinder 20 is installed on the feed hopper 3. The output end is fixedly connected to the connecting plate 18. By starting the electric cylinder 20, the output end of the electric cylinder 20 drives the connecting plate 18 to slide along the inner wall of the through groove 19. The connecting plate 18 drives the extrusion plate 16 to move along the inner wall of the limiting slide groove 11. The extrusion plate 16 drives the arc extrusion head 17 to move upward at an angle and contact and extrude the arc surfaces 10 on multiple fixed plates 9 in sequence. The arc extrusion head 17 pushes the fixed plate 9 to move into the slot 15. The fixed plate 9 drives the limiting plate 12 to slide along the inner wall of the snap-fit ​​groove 13 and extrude the connecting spring 14. The connecting spring 14 contracts and generates a spring force in the opposite direction. When the extrusion plate 16 does not contact the fixed plate 9, the baffle plate 7 connected to the rotating shaft 25 will be subjected to the gravity of the raw material. The rotating shaft 25 will rotate in the direction away from the opening. The raw material in the storage bin is poured out and enters the sealing shell 2 through the communication port between the feed hopper 3 and the sealing shell 2 for upward lifting. The feed hopper 3 has an abutment groove 24 that cooperates with the baffle plate 7 to support the baffle plate 7. The abutment groove 24 is located at the opening away from the feed hopper and is on the side of the first rotating baffle plate 7. The other end of the rotating shaft 25 is coaxially fixed with a rocker arm 22 to drive the rotating shaft 25 to rotate so that the slot 15 connects with the limiting slide groove 11. As multiple baffle plates 7 rotate in sequence, the first rotating baffle plate 7 contacts the abutment groove 24 and is supported, allowing material to be discharged. The subsequent rotating baffle plates 7 will contact and be supported by the rotating roller 6 on one side after rotation. When multiple baffle plates 7 have rotated and discharged material, one end of the fixed plate 9 is not connected to the limiting slide groove 11, and can be connected by rotating the roller 6. The rocker arm 22 drives the rotating shaft 25 to rotate, causing the fixed plate 9 to re-insert into the limiting slide groove 11 under the elastic force of the connecting spring 14. This causes the multiple baffle plates 7 to divide the feeding space 5 into multiple storage bins again. It should be noted that when the rocker arm 22 drives the rotating shaft 25 to rotate, the electric cylinder 20 needs to be activated at the same time to drive the extrusion plate 16 back to its original position. When the contact plane 21 on the rotating shaft 25 is parallel to the limiting slide groove 11, the extrusion plate 16 needs to be driven through the limiting slide groove 11 and the contact plane 21 so that the rotating shaft 25 does not block the movement of the extrusion plate 16, so that the arc extrusion head 17 faces the multiple arc surfaces 10 for the next interval feeding. Working principle: When this MPP / PE cable protection pipe raw material lifting device lifts granular raw materials, the fixed plate 9 is engaged in the limiting slide groove 11. By feeding material into multiple storage bins, the raw material in the feeding space 5 is divided into multiple small portions. By activating the electric cylinder 20, the output end of the electric cylinder 20 drives the connecting plate 18 to slide along the inner wall of the through groove 19. The connecting plate 18 drives the extrusion plate 16 to move along the inner wall of the limiting slide groove 11. The extrusion plate 16 drives the arc extrusion head 17 to move upward at an angle, and sequentially contacts and extrudes the arc surfaces 10 on multiple fixed plates 9. The arc extrusion head 17 pushes the fixed plate 9 into the slot 15. The fixed plate 9 drives the limiting plate 12 to slide along the inner wall of the engaging groove 13 and extrude the connecting spring 14. The connecting spring 14 contracts and generates a spring in the opposite direction. When the extrusion plate 16 is not in contact with the fixed plate 9, the baffle plate 7 connected to the rotating shaft 25 will be subjected to the gravity of the raw material. The rotating shaft 25 will rotate in the direction away from the opening, and the raw material in the storage bin will be poured out. The raw material can avoid blockage in the auger by being discharged in sequence. Then, it will enter the sealing shell 2 through the communication port between the feed hopper 3 and the sealing shell 2 and be lifted upward. After that, the extrusion plate 16 can be moved by rotating the rocker arm 22 in conjunction with the electric cylinder 20, which will drive the rotating shaft 25 to rotate and drive the fixed plate 9 to re-insert into the limiting slide groove 11 under the elastic force of the connecting spring 14. This will cause the multiple baffle plates 7 to divide the feeding space 5 into multiple storage bins again, and cause the arc extrusion head 17 on the extrusion plate 16 to face the multiple arc surfaces 10 again, which will facilitate the next interval discharge.
