Description

Technical Field

[0001] The present invention relates to the field of polyethylene pipe recycling, in particular to equipment for producing polyethylene wound structure wall A-type pipes. Background Art

[0002] Polyethylene spiral wound pipe is a lightweight, high-rigidity plastic pipe made of high-density polyethylene through a spiral winding molding process. It is widely used in municipal drainage, industrial sewage discharge, rainwater collection and other fields.

[0003] In the process of producing polyethylene pipes, in order to reduce production costs, a certain proportion of recycled materials is usually mixed with new materials, and then the mixture is used to produce polyethylene pipes. In the existing technology, after the waste pipes are recycled, they need to be melted and reused. Before melting the pipes, a crushing device is needed to crush them into small particles and then heat and melt them to improve the melting efficiency of the pipes. Currently, common crushing devices usually use two crushing rollers to directly extrude and crush the pipes. However, since the outer wall of the pipe is relatively smooth and the pipe itself is relatively light, when the diameter of the pipe is larger than the spacing between the tooth-like structures on the two crushing rollers, the tooth-like structures on the two crushing rollers are difficult to quickly grab the intact pipes. At this time, workers usually need to press the pipes down with handheld tools to cooperate with the crushing rollers to crush the pipes, which poses a major safety hazard.

[0004] To this end, it is necessary to design a device that can classify waste pipes according to their diameter and integrity and can cut and crush pipes with larger diameter and in good condition, in order to address the shortcomings of existing equipment such as the lack of preliminary crushing structure, which makes it difficult for the crushing roller to quickly grab intact pipes and crush them. Summary of the Invention

[0016] The present invention has the following advantages: 1. The device can screen waste polyethylene pipes according to their diameter and whether they are broken or not. The intact polyethylene pipes with a larger diameter will fall into the cutting frame after passing through the separation frame and be cut and broken. The damaged polyethylene pipes with a smaller diameter will directly enter the crushing frame through the feeding frame for crushing. The polyethylene pipes after cutting will eventually fall into the crushing frame. The large-diameter polyethylene pipes will be quickly caught and broken by the crushing roller after cutting, which can effectively prevent the intact large-diameter polyethylene pipes from being difficult to be caught by the crushing roller due to their too smooth outer walls during crushing, thereby improving the crushing efficiency.

[0017] 2. The vertical cutting action of the cutting saw blade can efficiently split large-diameter pipes, and the cutting saw blade can slide back and forth on the sliding plate while descending to achieve horizontal cutting action, thereby improving cutting efficiency and avoiding continuous rigid contact between the saw blade and the pipe, thereby extending the life of the saw blade. After each cutting is completed, the kinetic energy of the sliding frame can be used to drive the rotating push frame to rotate, so as to adjust the position of the cutting saw blade and fully cut the pipe.

[0018] 3. As the sliding frame descends, the lifting push rod also descends, and then pushes the sliding extrusion plate through the wedge block to clamp the pipe to prevent the pipe from shifting during the cutting process.

[0019] 4. During the rotation of the chain, the swing push rod continuously swings and pushes the sliding rod to insert into the separation frame, so as to drive the pipe to move in the separation frame to avoid pipe accumulation, and the end of the sliding rod facing the pipe is inclined. When the sliding rod contacts the pipe wall, it can automatically slide outward and bypass the pipe wall. When the pipe passes through the rectangular through hole in the separation frame, the swing pull rod can pull the sliding rod out of the separation frame through the sliding claw to disengage the sliding rod from the pipe.

[0020] 5. When the fixed card moves to the swing baffle, the sliding plate drives the cutting saw blade down again and rises to reset after cutting the pipe. The fixed card will push the connecting frame upward through the swing baffle so that the fixed card no longer contacts the rotating push frame, causing the sliding plate and cutting saw blade to automatically move to reset.

DETAILED DESCRIPTION

[0032] To make the objectives, technical solutions, and advantages of the present invention more apparent, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that any directional terms such as "up," "down," "left," "right," "front," "back," "inside," and "outside" that appear or will appear herein are based solely on the accompanying drawings and are not intended to limit the present invention.

[0033] Example 1: A device for producing polyethylene winding structure wall type A pipe, such as Figures 1-10As shown, it includes a frame 1, a separation frame 101, a rotating guide rod 1011, a feeding frame 102, a slitting frame 103, a receiving bottom plate 1031, a guide rod 1032, a crushing frame 104, a crushing roller 105 and a cutting mechanism. The separation frame 101 is fixedly connected to the frame 1, and a rectangular through hole is opened at the bottom of the separation frame 101. The rotating guide rods 1011 are evenly spaced and rotatably connected in the separation frame 101. The rotating guide rods 1011 are located at the rectangular through hole at the bottom of the separation frame 101. The feeding frame 102 is fixedly connected to the frame 1, and the feeding frame 102 is located at the bottom of the separation frame 101. The top inlet of the feeding frame 102 is aligned with the rectangular through hole at the bottom of the separation frame 101. The slitting frame 103 is fixed to the frame 1. Frame 103 is located at the outlet of the separation frame 101, and a guide rod 1032 is fixedly connected to the bottom of the slitting frame 103. The guide rod 1032 is slidably connected to a receiving bottom plate 1031 outside the guide rod 1032. The receiving bottom plate 1031 is located at the bottom of the slitting frame 103. The polyethylene pipe that slides out of the separation frame 101 falls onto the receiving bottom plate 1031 in the slitting frame 103. A crushing frame 104 is fixedly connected to the frame 1, and the crushing frame 104 is located at the bottom of the slitting frame 103. The outlet of the feeding frame 102 is connected to the crushing frame 104. A crushing roller 105 is rotatably connected in the crushing frame 104, and the two crushing rollers 105 rotate towards each other. The cutting mechanism is installed on the frame 1, and the cutting mechanism is used to cut and crush the polyethylene pipe in the slitting frame 103.

[0034] The waste polyethylene pipes are placed in the separation frame 101. During the rolling of the polyethylene pipes along the separation frame 101, the polyethylene pipes with smaller diameters or broken polyethylene pipes will directly fall down from the rectangular through-holes at the bottom of the separation frame 101 into the feeding frame 102. The polyethylene pipes with a diameter greater than the distance between the two rotating guide rods 1011 will fall along the separation frame 101 onto the receiving bottom plate 1031 in the slitting frame 103. The polyethylene pipes in the feeding frame 102 will directly fall into the crushing frame 104. The two crushing rollers 105 rotate in opposite directions to directly crush the polyethylene pipes passing through the feeding frame 102. The polyethylene pipes entering the slitting frame 103 have a larger diameter. The polyethylene pipes in the slitting frame 103 are first cut and crushed by the cutting mechanism, and then the receiving bottom plate 1031 is controlled to slide along the guide rod 1032, so that the polyethylene pipes in the slitting frame 103 fall downward into the crushing frame 104 and are crushed, so as to improve the crushing efficiency.

[0035] Example 2: Based on Example 1, Figure 7-10As shown, the cutting mechanism includes a fixed frame 201, a rotating shaft 3, a rotating motor 301, a connecting rod 302, a sliding frame 303, a sliding plate 4, a cutting saw blade 503, a sliding cutting assembly and a positioning assembly. The top of the frame 1 is fixed with a fixed frame 201, the fixed frame 201 is rotatably connected to the rotating shaft 3, the fixed frame 201 is mounted with a rotating motor 301, the output shaft of the rotating motor 301 is connected to the rotating shaft 3, the end of the rotating shaft 3 away from the rotating motor 301 is fixed with a vertical straight guide groove, and the sliding shaft 3 is slidably connected in the frame 1. The frame 303 is rotatably connected to the connecting rod 302 on the sliding frame 303, and the other end of the connecting rod 302 is rotatably connected to the straight guide groove at the end of the rotating shaft 3. The sliding frame 303 is slidably connected to the sliding plate 4, and the sliding plate 4 is equipped with a cutting saw blade 503. The sliding cutting assembly is installed on the mounting plate, and the sliding cutting assembly is used to drive the cutting saw blade 503 to slide back and forth to cut the polyethylene pipe. The positioning assembly is installed on the sliding plate 4, and the positioning assembly is used to adjust the position of the cutting saw blade 503 to cut the polyethylene pipe at different positions.

[0036] The polyethylene pipe entering the slitting frame 103 falls on the receiving bottom plate 1031, and then the rotating motor 301 is started. The rotating motor 301 rotates through the rotating shaft 3. When the rotating shaft 3 rotates, it drives the sliding frame 303 to slide up and down along the frame 1 through the connecting pull rod 302, and the sliding plate 4 and the cutting saw blade 503 move up and down accordingly. During the descent of the cutting saw blade 503, the sliding cutting assembly can make the cutting saw blade 503 slide back and forth to cut the polyethylene pipe in the slitting frame 103. Every time the sliding frame 303 rises and resets, the positioning assembly will automatically adjust the position of the sliding plate 4, the cutting saw blade 503 and the sliding cutting assembly to cut the polyethylene pipe in the slitting frame 103 from different positions.

[0037] like Figure 8 As shown, the sliding cutting assembly includes a cutting motor 5, a rotating block 501 and a reciprocating slide 502. The cutting motor 5 is installed on the sliding plate 4. The rotating block 501 is rotatably connected to the sliding plate 4. The reciprocating slide 502 is slidably connected to the sliding plate 4. A cutting saw blade 503 is fixed to the bottom of the reciprocating slide 502. A straight hole is provided on the reciprocating slide 502. The round rod in the eccentric position of the rotating block 501 is slidably connected to the straight hole on the reciprocating slide 502. When the rotating block 501 rotates, it can drive the reciprocating slide 502 to slide back and forth along the sliding plate 4.

[0038] During the descent of the sliding plate 4, the cutting motor 5 is started, and the cutting motor 5 drives the reciprocating slide 502 to slide along the sliding plate 4 through the rotating block 501, and the cutting saw blade 503 moves back and forth continuously to perform transverse cutting of the polyethylene pipe, thereby improving the cutting efficiency and preventing the cutting saw blade 503 from being damaged due to rigid collision.

[0039] like Figures 8-10 As shown, the positioning assembly includes a fixed rack 308, a fixed clamping plate 401, a second return spring 402, a connecting frame 6, a fixed rod 601, a one-way gear 602, a rotating push frame 603 and a clamping assembly. The sliding frame 303 is fixedly connected to the fixed rack 308, the fixed frame 201 is slidably connected to the connecting frame 6, the connecting frame 6 is fixedly connected to the fixed rod 601, the fixed rod 601 is rotatably connected to the one-way gear 602, and the fixed rod 601 is rotatably connected to the rotating push frame through a one-way bearing. 603, the one-way gear 602 is connected to the rotating push frame 603, and a fixed clamping plate 401 is fixed to the sliding plate 4. A second return spring 402 is provided between the sliding plate 4 and the sliding frame 303. One end of the second return spring 402 is fixed to the sliding plate 4, and the other end is fixed to the sliding frame 303. The clamping assembly is installed on the fixed frame 201. During the process of the sliding plate 4 descending and cutting the polyethylene pipe, the clamping assembly can limit the sliding plate 4 to prevent the sliding plate 4 from shaking during the cutting process.

[0040] like Figure 8 As shown, the clamping assembly includes a sliding locking plate 305, a buffer spring 306 and a fixed blocking rod 307. The fixed blocking rod 307 is fixed to the fixed frame 201, and the sliding locking plate 305 is slidably connected to the sliding frame 303. A buffer spring 306 is provided between the sliding locking plate 305 and the sliding frame 303. One end of the buffer spring 306 is fixed to the sliding frame 303, and the other end is fixed to the sliding locking plate 305. The fixed blocking rod 307 is located at the top of the sliding locking plate 305.

[0041] When the sliding frame 303 is lowered, the fixed rack 308 and the sliding plate 4 are lowered accordingly, and the fixed rack 308 will not drive the rotating pushing frame 603 to rotate through the one-way gear 602 during the lowering process of the sliding plate 4. When the sliding plate 4 is lowered, before the rotating pushing frame 603 is disengaged from the fixed card plate 401, the fixed card plate 401 has been locked in the slot on the sliding card plate 305. When the rotating pushing frame 603 is disengaged from the fixed card plate 401, the fixed card plate 401 and the sliding plate 4 will not rock in the direction perpendicular to the cutting saw blade 503 under the action of the sliding card plate 305. When the sliding frame 303 rises and resets, the fixed rack 308 and the sliding plate 4 rise and reset accordingly. After the fixed card plate 401 rises and disengages from the slot on the sliding card plate 305, the fixed rack 308 just contacts with the one-way gear 602 and drives it along When the cam 303 is lifted up, the spring 306 between the sliding plate 305 and the sliding plate 303 is compressed, and the fixed plate 401 can slide out of the sliding plate 305.

[0042] Example 3: Based on Example 2, Figure 2 and Figure 7As shown, it also includes an extrusion mechanism for tightening the pipe in the cutting frame 103, the extrusion mechanism includes a rotating baffle 1012, a first return torsion spring 1013, a fixed block 1014, a sliding extrusion plate 1033, a wedge block 1034, a first return spring 1035, a bending push rod 1036 and a lifting push rod 304, the separation frame 101 is rotatably connected to the rotating baffle 1012, a first return torsion spring 1013 is provided between the rotating baffle 1012 and the separation frame 101, a fixed block 1014 is fixed to the outside of the rotating baffle 1012, and a sliding extrusion plate 1033 is slidably connected to the cutting frame 103.

One end of the first return spring 1035 is fixed to the sliding extrusion plate 1033, and the other end is fixed to the slitting frame 103. A wedge block 1034 is fixed to the outer side of the sliding extrusion plate 1033. A bending push rod 1036 is fixed to the top of the sliding extrusion plate 1033. The bending push rod 1036 is in contact with the fixed block 1014. A lifting push rod 304 is fixed to the sliding frame 303. The lifting push rod 304 is in contact with the wedge block 1034. When the lifting push rod 304 descends, it can push the sliding extrusion plate 1033 to slide along the slitting frame 103 through the wedge block 1034.

[0043] When the sliding frame 303 descends, the lifting push rod 304 also descends. When the lifting push rod 304 descends, it pushes the sliding extrusion plate 1033 to slide along the slitting frame 103 through the wedge block 1034 and compresses the first return spring 1035 to press the polyethylene pipe in the slitting frame 103 tightly to ensure that the cutting saw blade 503 cuts and breaks the polyethylene pipe. In the process of the sliding extrusion plate 1033 sliding along the slitting frame 103, the bending push rod 1036 pushes the rotating baffle 1012 to rotate around the separation frame 101 through the fixed block 1014 and causes the first return torsion spring 1013 to accumulate force and deform, so as to press the separation frame 101 1 is blocked to prevent new polyethylene pipes from falling into the slitting frame 103 during the cutting process. When the sliding frame 303 rises and resets, the lifting push rod 304 rises and resets accordingly. Under the push of the first reset spring 1035, the sliding extrusion plate 1033 and the wedge block 1034 slide and reset along the slitting frame 103, and the bending push rod 1036 moves and resets accordingly. Under the action of the first reset torsion spring 1013, the fixed block 1014 and the rotating baffle 1012 rotate and reset and reopen the outlet of the separation frame 101, so that the polyethylene pipe in the separation frame 101 can re-enter the slitting frame 103.

On the moving block 202, a sliding rod 2021 is slidably connected in the sliding block 2022. The two sliding rods 2021 on the same moving block 202 are separated from each other at one end close to the separation frame 101. The pushing insertion component is installed on the fixed frame 201. The pushing insertion component is used to push the sliding rod 2021 to be inserted into the tubular polyethylene pipe in the separation frame 101, so as to drive the polyethylene pipe to move along the separation frame 101 when the chain 2 rotates. The loosening component is installed on the fixed frame 201. The loosening component can pull the sliding rod 2021 to slide along the sliding block 2022 in the direction away from the separation frame 101 and disengage from the tubular polyethylene pipe.

[0046] like Figure 6 As shown, the release assembly includes a swinging rod 209, a sliding claw 210 and a connecting spring 211. The swinging rod 209 is rotatably connected to the fixed frame 201. A return torsion spring 208 is provided between the swinging rod 209 and the fixed frame 201. The sliding claw 210 is slidably connected to the swinging rod 209. The sliding claw 210 and the swinging rod 209 are connected by a connecting spring 211. One end of the connecting spring 211 is fixed to the swinging rod 209, and the other end is fixed to the sliding claw 210.

[0047] When the chain 2 rotates, it drives the moving block 202 to rotate, and the rotating shaft 203 drives the transmission shaft 205 to rotate through the belt transmission member 204. The transmission shaft 205 can swing through the bevel gear transmission group 207 and deform the return torsion spring 208. When the moving block 202 rotates to the side opening of the separation frame 101, the swing push rod 206 pushes the two sliding rods 2021 on the moving block 202 that move to the side opening of the separation frame 101 to move each time, so that the two sliding rods 2021 are inserted into the separation frame 101. When the sliding rods 2021 are inserted into the separation frame 101, they are inserted into the polyethylene tube. When the sliding rod 2021 contacts the wall of the polyethylene pipe, the end of the sliding rod 2021 opens outwards. During the insertion of the sliding rod 2021 into the separation frame 101, the sliding rod 2021 drives the sliding block 2022 to slide along the moving block 202 under the action of the polyethylene pipe wall and compresses the return spring 2023, so that the sliding rod 2021 can bypass the wall of the polyethylene pipe and be inserted into the polyethylene pipe. Then, the movement continues to move with the chain 2, and the sliding rod 2021 will drive the polyethylene pipe to move along the separation frame 101 to prevent the polyethylene pipe from piling up in the separation frame. 101, when the sliding rod 2021 drives the polyethylene pipe to pass through the rectangular through hole in the separation frame 101, the moving block 202 just moves to the swing rod 209, and the swing rod 209 rotates simultaneously with the swing push rod 206, and when the swing rod 209 rotates downward to the maximum swing angle, the sliding claw 210 can just be stuck on the sliding rod 2021 on the corresponding moving block 202, and when the swing rod 209 swings back to its original position driven by the return torsion spring 208, the sliding claw 210 moves accordingly and pulls the sliding rod 2021 to slide out of the separation frame 101 along the sliding block 2022, and As the swing rod 209 continues to swing upward, the length of the sliding rod 2021 pulled outward continues to increase. During this process, the sliding rod 2021 will pull the sliding claw 210 to slide downward along the swing rod 209 and stretch the connecting spring 211. When the sliding rod 211 slides out of the separation frame 101, the sliding block 2022 will limit the sliding rod 210 from continuing to move. At this time, the swing rod 209 continues to swing back to its original position, and the sliding claw 210 will disengage from the sliding rod 21. At this time, driven by the connecting spring 211, the sliding claw 210 swings upward along the swing rod 209 to its original position.

[0048] like Figure 10As shown, it also includes a reset mechanism for sliding the sliding plate 4, which includes a swinging baffle 604, a second reset torsion spring 605, a third reset spring 606, a downward pressure spring 607 and a U-shaped slide 608. The U-shaped slide 608 is slidably connected to the connecting frame 6, and the swinging baffle 604 is rotatably connected to the U-shaped slide 608. The swinging baffle 604 and the U-shaped slide 608 are connected through the second reset torsion spring 605, and the U-shaped slide 608 and the connecting frame 6 are connected through the third reset spring 606. One end of the third reset spring 606 is fixed to the connecting frame 6, and the other end is fixed to the U-shaped slide 608. A downward pressure spring 607 is provided between the connecting frame 6 and the fixed frame 201, and one end of the downward pressure spring 607 is fixed to the connecting frame 6, and the other end is fixed to the fixed frame 201.

[0049] When the sliding plate 4 is lifted up, the fixed card 401 will push the connecting frame 6 to slide upward through the swing baffle 604 and the U-shaped slide 608 and compress the downward pressure spring 607. In this case, when the fixed card plate 401 slides out of the slot on the sliding card plate 305, the fixed card plate 401 and the sliding plate 4 are no longer restricted by the sliding card plate 305 and the rotating push frame 603. The second return spring 402 pushes the sliding plate 4 and the fixed card plate 401 to slide and reset along the sliding frame 303, and at the same time drives the cutting saw blade 503 to slide and reset. The U-shaped slide plate 608, the swing baffle 604, and the second return torsion spring 605 slide along the connecting frame 6 with the fixed card plate 401 and compress the third return spring 606. When the fixed card plate 401 drops again with the sliding plate 4, the fixed card plate 401 disengages from the slot at the bottom of the swing baffle 604. At this time, under the push of the third return spring 606, the U-shaped slide plate 608, the swing baffle 604 and the second return torsion spring 605 slide and reset along the connecting frame 6.
