Abstract
Description
Technical Field
[0001] The utility model relates to the field of plastic pipe sorting, in particular to an automatic sorting device for waste plastic pipes. Background Technique
[0002] When recycling waste plastic pipes, it is necessary to sort them according to different diameters and lengths. Traditional sorting methods often rely on manual measurement and judgment, and then the manually sorted pipe fittings are put into the next mechanical sorting device. This process not only consumes a large amount of manpower and time, but also is prone to human errors, resulting in inaccurate sorting results. Workers need to measure the diameter and length of each plastic pipe one by one and then classify and place them. This method is extremely inefficient and cannot meet the needs of large-scale recycling and processing.
[0003] Therefore, an automatic sorting device for waste plastic pipes is proposed. Content of the Utility Model
[0004] In view of the above problems, the utility model provides an automatic sorting device for waste plastic pipes to solve the problems put forward in the above background technique.
[0005] The technical solution of the utility model is as follows:
[0006] An automatic sorting device for waste plastic pipes includes symmetrically arranged support frames. There are equidistantly distributed rollers drivingly engaged between the two support frames. Each roller surface is provided with sorting openings, and the opening widths and lengths of each sorting opening are sequentially set from large to small. A receiving box is arranged below each roller, and a collection box is fixedly connected to the bottom end of the receiving box.
[0007] The working principle of the above technical solution is as follows:
[0008] First, place the waste plastic pipes on the rollers between the symmetric support frames. Due to the driving engagement between the rollers, the plastic pipes will be driven forward. As the plastic pipes move on the rollers, the smaller plastic pipes will first encounter the sorting openings with smaller opening widths and lengths and thus fall into the corresponding receiving boxes. Then, the larger plastic pipes will continue to move forward and fall into the corresponding receiving boxes when they encounter the larger sorting openings that match their sizes. The plastic pipes that fall into the receiving boxes will further fall into the collection boxes fixedly connected to the bottom ends, completing the sorting and collection process.
[0009] In a further technical solution, pulleys are rectangularly distributed at the bottom end of the collection box. A bottom plate is arranged below the collection box, and symmetrically arranged chutes are opened on the top surface of the bottom plate. The pulleys are slidably engaged with the inner walls of the chutes.
[0010] Through the above technical solution, when the collection box is full of waste plastic pipes, the collection box can be easily pulled out of the device through the sliding cooperation of the pulley and the chute, without the need for strenuous handling, saving manpower and time.
[0011] In a further technical solution, the opposite surfaces of the two support frames are fixedly connected with rotating bolts through bearings, the ends of the rotating bolts are fixedly connected with second gears, both ends of the roller are fixedly connected with rotating shafts, the ends of the rotating shafts are fixedly connected with first gears, the first gears and the second gears are meshed and connected, and a motor is fixedly connected to the outer surface of the support frame, and the output end of the motor is fixedly connected with one of the rotating bolts.
[0012] Through the above technical solution, through the meshing connection of the gears, all the rollers can be synchronously rotated through gear transmission, ensuring the stable transportation of waste plastic pipes during the sorting process and avoiding situations such as jamming and out-of-sync.
[0013] In a further technical solution, baffles are fixedly connected to the ends of the two support frames, and the two baffles are symmetrically inverted V-shaped.
[0014] Through the above technical solution, the inverted V-shaped baffles can effectively guide the waste plastic pipes into the space between the rollers, ensuring that the plastic pipes can be accurately placed in the working area of the sorting device, reducing deviation and omission during feeding, and at the same time preventing the plastic pipes from falling from both sides to a certain extent during feeding, improving the stability and safety of feeding.
[0015] In a further technical solution, support columns are fixedly connected to the bottom ends of the support frames, the bottom ends of the support columns are fixedly connected to the top surface of the bottom plate, and through grooves are provided between each support column.
[0016] Through the above technical solution, the support columns provide stable support for the support frames, ensuring that the entire automatic sorting device for waste plastic pipes remains stable during operation without shaking or tilting, thereby ensuring the accuracy and reliability of the sorting work.
[0017] In a further technical solution, inclined plates are fixedly connected to both sides of the inner wall of the receiving frame, and the receiving frame is a conical shape with a larger top and a smaller bottom.
[0018] Through the above technical solution, the inclined plates on both sides of the inner wall can guide the waste plastic pipes falling from the sorting opening to slide more smoothly into the collection box, reducing jamming and accumulation of the plastic pipes in the receiving frame.
[0019] In a further technical solution, anti-slip particles are fixedly connected to the surface of the roller.
[0020] Through the above technical solution, the anti-slip particles can increase the friction between the roller and the waste plastic pipe, enabling the plastic pipe to move more stably on the roller, reducing the slipping phenomenon, and improving the accuracy and efficiency of sorting.
[0021] Compared with the prior art, the utility model has the following beneficial effects:
[0022] By setting symmetric support frames, rollers with sorting ports, receiving frames, and collection bins, automatic sorting of waste plastic pipes is achieved, without relying on manual measurement and judgment. By setting inverted V-shaped baffles, effective guidance and preliminary sorting of the incoming material are realized, reducing the deviation of the incoming material. By setting inclined plates on the inner wall of the receiving frame and designing the receiving frame as a conical shape with a larger top and a smaller bottom, smooth sliding and centralized collection of plastic pipes are achieved. By setting anti-slip particles on the surface of the roller, enhanced friction is realized to ensure stable transmission of plastic pipes. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Embodiment:
[0033] Please refer to Figures 1-4 , an automatic sorting device for waste plastic pipes, including symmetrically arranged support frames 1. There are equidistantly distributed rollers 2 drivingly engaged between the two support frames 1. Each roller 2 has a sorting opening 3 on its surface. The opening width and length of each sorting opening 3 are arranged in decreasing order successively. A receiving box 4 is arranged below each roller 2, and a collecting box 5 is fixedly connected to the bottom end of the receiving box 4.
[0034] The working principle of the above technical solution is as follows:
[0035] First, place the waste plastic pipes on the rollers 2 between the symmetric support frames 1. Since the rollers 2 are drivingly engaged with each other, it will drive the plastic pipes to move forward. As the plastic pipes move on the rollers 2, the smaller-sized plastic pipes will encounter the sorting openings 3 with smaller opening widths and lengths first, and thus fall into the corresponding receiving boxes 4. Then, the larger-sized plastic pipes will continue to move forward. When they encounter the larger sorting openings 3 that match their sizes, they will fall into the corresponding receiving boxes 4. The plastic pipes that fall into the receiving boxes 4 will further fall into the collecting boxes 5 fixedly connected to the bottom ends, completing the sorting and collection process.
[0036] Please refer to Figure 1 and Figure 4 , pulleys 9 are rectangularly distributed at the bottom end of the collecting box 5. A bottom plate 7 is arranged below the collecting box 5. Symmetrically arranged sliding grooves 8 are opened on the top surface of the bottom plate 7. The pulleys 9 are slidably engaged with the inner walls of the sliding grooves 8.
[0037] When the collection box 5 is full of waste plastic pipes, through the sliding fit of the pulley 9 and the chute 8, the collection box can be easily pulled out of the device without strenuous handling, saving manpower and time.
[0038] Please refer to Figure 2 and Figure 3 , on the opposite surfaces of the two support frames 1, rotating bolts 13 are fixedly connected through bearings. The ends of the rotating bolts 13 are fixedly connected with second gears 12. Both ends of the roller 2 are fixedly connected with rotating shafts 10. The ends of the rotating shafts 10 are fixedly connected with first gears 11. The first gears 11 and the second gears 12 are meshed and connected. The outer surface of the support frame 1 is fixedly connected with a motor 14, and the output end of the motor 14 is fixedly connected with one of the rotating bolts 13.
[0039] Through the meshing connection of the gears, all the rollers 2 can achieve synchronous rotation through gear transmission, ensuring the smooth conveyance of waste plastic pipes during the sorting process and avoiding situations such as jamming and non-synchronization.
[0040] Please refer to Figure 1 , the ends of the two support frames 1 are both fixedly connected with baffles 6, and the two baffles 6 are symmetrically arranged in an inverted V shape.
[0041] The inverted V-shaped baffles 6 can effectively guide the waste plastic pipes into the space between the rollers 2, ensuring that the plastic pipes can be accurately placed in the working area of the sorting device, reducing deviation and omission during feeding, and at the same time preventing the plastic pipes from falling from both sides to a certain extent during the feeding process, improving the stability and safety of feeding.
[0042] Please refer to Figure 1 and Figure 2 , the bottom ends of the support frames 1 are fixedly connected with support columns 15, the bottom ends of the support columns 15 are fixedly connected to the top surface of the bottom plate 7, and through grooves 16 are provided between each support column 15.
[0043] The support columns 15 provide stable support for the support frames 1, ensuring that the entire automatic waste plastic pipe sorting device remains stable during operation without shaking or tilting, thereby guaranteeing the accuracy and reliability of the sorting work.
[0044] Please refer to Figure 1 and Figure 4 , both sides of the inner wall of the receiving box 4 are fixedly connected with inclined plates 41, and the receiving box 4 is in a conical shape with a larger top and a smaller bottom.
[0045] The inclined plates 41 on both sides of the inner wall can guide the waste plastic pipes falling from the sorting opening to slide more smoothly into the collection box 5, reducing jamming and accumulation of the plastic pipes in the receiving box 4.
[0046] Please refer to Figure 1 and Figure 2, anti-slip particles 21 are fixedly connected to the surface of the roller 2.
[0047] The anti-slip particles 21 can increase the friction between the roller 2 and the waste plastic pipe, enabling the plastic pipe to move more stably on the roller 2, reducing the slipping phenomenon, and improving the accuracy and efficiency of sorting.
[0048] During operation, first, start the motor 14. The output end of the motor 14 drives the rotating bolt 13 connected thereto to rotate, and the second gear 12 at the end of the rotating bolt 13 rotates accordingly. Since the second gear 12 is meshed with the first gear 11, the first gear 11 drives the rotating shaft 10 to rotate, thereby causing the roller 2 to start rotating. Then, place the waste plastic pipe between the symmetrically arranged baffles 6 in an inverted V shape. The plastic pipe enters the surface of the rollers 2 that are driven side by side under the guidance of the baffles 6. Then, with the rotation of the rollers 2, plastic pipes of different diameters and lengths will move forward under the action of the friction of the anti-slip particles 21. When the plastic pipe encounters the sorting opening 3 that matches its size, it will fall into the corresponding receiving box 4 below from the sorting opening 3. The receiving box 4 is a conical shape with a larger top and a smaller bottom, and inclined plates 41 are fixedly connected to both sides of the inner wall, which can guide the falling plastic pipe to smoothly slide into the collection box 5. When the collection box 5 is full, the collection box 5 can be conveniently pulled out for subsequent processing.
[0049] The above embodiments only represent the specific implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
