Description

Technical Field

[0001] The invention relates to the technical field of PE pipe waste recycling, and in particular to a hydraulic shearing type PE pipe waste recycling device. Background Art

[0002] PE pipe generally refers to polyethylene pipe, which is a pipe made of polyethylene as the main material. It has a wide range of applications, from small-section yellow pipes for natural gas to thick-walled black pipes with a diameter of 48in for industrial and urban pipelines. Large-diameter hollow wall pipes are used as substitutes for concrete rainwater drain pipes and other sewer pipelines, which are growing rapidly.

[0003] In order to facilitate recycling, PE pipes are generally crushed before recycling. However, some large PE pipes have large diameters and are very long, which makes it impossible for the pipes to be directly put into the crusher for crushing, thereby increasing the difficulty of crushing the PE pipes. In addition, manual feeding is required when cutting the pipes, and the cutting is uneven, which is time-consuming and labor-intensive. Summary of the invention

[0004] In view of the deficiencies of the prior art, the present invention provides a hydraulic shearing type PE pipe waste recycling equipment, which overcomes the deficiencies of the prior art and effectively solves the problems of difficulty in crushing and time-consuming and labor-intensive manual feeding.

[0021] 2. The hydraulic shearing type PE pipe waste recycling equipment of the present invention, in the feeding assembly, the sliding sleeve can be controlled to move downward by the descending of the shearing seat, thereby controlling the lever to tilt and push the vertebral body on the push-pull rod downward. Each time the shearing seat moves downward, the push-pull rod will be driven to carry the PE pipe toward the direction of the cutter for a distance, thereby realizing the automatic feeding of the PE pipe, having a compact structure and reasonable design, saving manpower, reducing production costs, and ensuring the consistency of the cut size of the PE pipe;

[0022] 3. The hydraulic shearing type PE pipe waste recycling equipment of the present invention can control the cutting disc and the vertical cutting knife to move downward at the same time by pushing the shearing seat downward through the hydraulic push rod, so that the PE pipe end can be cut while the PE pipe end is cut. On this basis, as the shearing seat descends, the vertical wedge block can be controlled to push the horizontal wedge block close to the PE pipe, and the horizontal cutting knife can cut the PE pipe flatly, thereby realizing the preliminary shearing of the PE pipe end and reducing the difficulty of crushing the PE pipe.

[0034] In this embodiment, in the hydraulic shearing mechanism 4, relying on the automatic feeding of the feeding component 43 can save manpower and reduce production costs. On this basis, the vertical shearing component 41 and the horizontal shearing component 42 can simultaneously complete the port shearing, vertical shearing and horizontal shearing of the PE pipe, thereby reducing the difficulty of subsequent crushing.

[0035] Example 2, refer to Figure 4 A hydraulic shearing type PE pipe waste recycling equipment, the vertical shearing assembly 41 includes a hydraulic push rod 411 fixedly connected to the top outer wall of the gantry 3 by screws, wherein the hydraulic push rod 411 includes two shear seats 412 horizontally distributed on the gantry 3, fixedly connected to the piston rod of the hydraulic push rod 411, a cutting disc 413 fixedly connected to the bottom outer wall of the shear seat 412 by screws, and a vertical cutter 414 welded to the outer wall of one side of the cutting disc 413;

[0036] The transverse shearing assembly 42 is composed of an arm 421, a vertical wedge 422, a transverse wedge 423, a transverse cutter 424, a cross column 425 and a spring 426, wherein the arm 421 includes two arms, both of which are welded to one side outer wall of the shearing seat 412, the vertical wedge 422 is welded to the bottom outer wall of the arm 421, the transverse wedge 423 is arranged at the bottom of the vertical wedge 422, the transverse cutter 424 is welded to one side outer wall of the transverse wedge 423, and the cross column 425 is welded to the other side outer wall of the transverse wedge 423, wherein the cross column 425 is slidably connected to the top outer wall of the shearing table 2, and the spring 426 is fixedly connected between the transverse wedge 423 and the shearing table 2.

[0037] In this embodiment, the hydraulic push rod 411 pushes the shear seat 412 to move downward, which can control the cutting disc 413 and the vertical cutting knife 414 to move downward at the same time, so that the PE pipe end can be cut while the PE pipe end is cut off. On this basis, as the shear seat 412 descends, the vertical wedge block 422 can be controlled to push the horizontal wedge block 423 close to the PE pipe, and the horizontal cutting knife 424 can cut the PE pipe flatly, thereby achieving preliminary shearing of the PE pipe end and reducing the difficulty of crushing the PE pipe.

[0039] In this embodiment, in the feeding assembly 43, the downward movement of the sliding sleeve 431 can be controlled by the descent of the shear seat 412, thereby controlling the lever 432 to tilt downward and push the vertebral body 435 on the push-pull rod 434. Each time the shear seat 412 moves downward, it will drive the push-pull rod 434 to carry the PE pipe toward the direction of the cutter for a certain distance, thereby realizing automatic feeding of the PE pipe. The structure is compact and the design is reasonable, which saves manpower, reduces production costs, and ensures the consistency of the cutting size of the PE pipe.

When the sliding sleeve 431 moves downward, the insertion rod 5 will first slide a distance inside the push plate 7 until the slider 6 abuts against the sliding sleeve 431. The insertion rod 5 will push the push plate 7 to continue moving downward, thereby pushing the vertebral body 435 on the push-pull rod 434 to translate again and again.

[0041] Reference Figure 3 The gantry 3 includes symmetrically distributed vertical frames 21 welded on the top outer wall of the shearing table 2, a horizontal plate 22 welded between the two vertical frames 21, and a reinforcing plate 23 welded between the vertical frames 21 and the horizontal plate 22. The gantry 3 is mainly responsible for installing two hydraulic push rods 411, and the hydraulic push rods 411 perform the lifting operation of the equipment.

[0042] Reference Figure 3 The inner wall at the top of the gantry 3 is welded with symmetrically distributed columns 20, and the sliding sleeve 431 is slidably connected to the outer wall of the column 20. Through the vertical setting of the column 20, the sliding sleeve 431 can ensure the stability of the shear seat 412 during the lifting process, avoiding shaking when the cutter cuts the PE pipe.

[0043] Reference Figure 5 A track 8 is provided on the top outer wall of the platform 1, and a pulley 439 is provided on the inner wall of the track 8. The pulley 439 is slidably connected to the top outer wall of the platform 1. The pulley 439 moves with the movement of the PE pipe. The pulley 439 is used to reduce the friction force when the PE pipe moves, and the pulley 439 is ensured to slide in a straight line through the limit of the track 8.

[0044] Reference Figure 5 A symmetrically distributed guide rod 9 is welded to the outer wall of one side of the bracket 438, and the guide rod 9 is slidably connected to the inner wall of the connecting plate 436. When the bracket 438 is moved by rotating the screw rod 437, in order to prevent the bracket 438 from shaking, the two guide rods 9 can play a good limiting role.

[0045] Reference Figure 5 A limiting frame 10 is welded to one end of the outer wall of the top of the shearing table 2, and the push-pull rod 434 is slidably connected to the inner wall of the limiting frame 10. On the one hand, the limiting frame 10 can play a supporting role to prevent the push-pull rod 434 from tilting, and on the other hand, it can limit the push-pull rod 434 from swinging left and right.

[0046] Reference Figure 2A crusher 12 is provided on the outer wall of one side of the platform 1 and the shearing table 2, and symmetrically distributed inclined rods 11 are welded between the platform 1, the shearing table 2 and the crusher 12. A conveyor 13 is installed on the outer wall of one side of the platform 1 at the bottom of the crusher 12. After shearing, the PE pipe will fall into the crusher 12 for crushing, and the crushed material will be discharged along the crusher 12 to the conveyor 13, and the waste will be recycled by relying on the transportation of the conveyor 13.

[0047] Reference Figure 7-8 The pulverizer 12 includes a pulverizing frame 14, a baffle 15 welded on the outer wall of the top of the pulverizing frame 14, adjacently distributed crushing rollers 16 rotatably connected to the inside of the pulverizing frame 14, gears 17 installed on the outer walls of one end of the two crushing rollers 16, and the two gears 17 are meshed with each other, a servo motor 18 fixedly connected to the outer wall of one side of the pulverizing frame 14 by screws, and a pulley group 19 installed on the servo motor 18 and the outer wall of one end of one of the crushing rollers 16. After the sheared PE pipe falls into the pulverizing frame 14, the two gears 17 are meshed with each other, and the transmission of the pulley group 19 is cooperated with the servo motor 18 to drive the crushing rollers 16 to rotate, so as to completely crush the PE pipe.

[0048] Working principle: First, the two ends of the PE pipe are placed on the shearing table 2 and the bracket 438 respectively. The bracket 438 is driven to move by rotating the screw rod 437 to prevent the PE pipe from falling off. The hydraulic push rod 411 pushes the shearing seat 412 to move downward to control the cutting disc 413 and the vertical cutting knife 414 to move downward at the same time. The cutting disc 413 is used to cut the end of the PE pipe, and the vertical cutting knife 414 is used to vertically cut the PE pipe. On this basis, as the shearing seat 412 descends, the vertical wedge block 422 can be controlled to push the horizontal wedge block 423 close to the PE pipe, and the PE pipe is cut flatly by the horizontal cutting knife 424, so that the end of the PE pipe is divided into four parts;

[0049] According to the above process, the shear seat 412 is lowered to control the sliding sleeve 431 to move downward, thereby controlling the lever 432 to tilt downward and push the vertebral body 435 on the push-pull rod 434. Each time the shear seat 412 moves downward, it will drive the push-pull rod 434 to carry the PE pipe toward the direction of the cutter for a distance, thereby completing the shearing of the PE pipe section by section. The sheared PE pipe will fall into the crusher 12 for crushing, and the crushed material will be discharged along the crusher 12 to the conveyor 13, and the waste will be recycled by relying on the transportation of the conveyor 13.
