Description

Technical Field

[0001] This invention relates to the field of plastic recycling technology, specifically to a recycling and processing device for plastic packaging boxes. Background Technology

[0002] Existing recycling equipment for plastic packaging boxes includes a vertically arranged feeding module, a double-roll crushing module, and a water bath cleaning module. During physical operation, the overall external geometry of the plastic packaging box is typically larger than the mechanical interlocking gap between adjacent crushing rollers. When the packaging box falls onto the crushing module under gravity, the material bounces upwards due to the contact tangential force of the rotating crushing rollers or becomes physically stuck in the space above the feed inlet, preventing continuous entry into the mechanical cutting area of ​​the crushing blades. When the irregularly shaped plastic fragments, after being mechanically crushed, fall downwards and contact the screen, fragments with geometric dimensions close to the inner diameter of the mesh become mechanically stuck inside the aperture. The stuck material continuously accumulates on the upper surface of the screen, covering the physical flow channel and blocking the vertical displacement path of subsequent material falling under gravity. Plastic fragments that pass through the screen and fall into the water bath cleaning module only move relative to the water flow in the liquid medium; the mechanical shearing force exerted by this hydrodynamic scouring on the material surface by impurities is insufficient to physically peel them off. After the cleaning process is completed, the solid plastic fragments and liquid cleaning water are in a mixed suspension or sedimentation state in the same tank space. Traditional devices rely on transferring the mixed materials to an independent solid-liquid separation device outside the current equipment for secondary processing, which increases the physical transfer steps of materials between different devices.

[0003] Therefore, the purpose of this invention is to provide a recycling and processing device for plastic packaging boxes to overcome the shortcomings of the prior art. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a recycling and processing device for plastic packaging boxes, which solves the problems of large-volume hollow plastic packaging boxes being difficult to enter the gap of the double roller crusher due to geometric size limitations, crushed particles physically getting stuck in the screen holes, and the inability to mechanically separate the solid-liquid mixed phase material after washing within a single box.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a recycling and processing device for plastic packaging boxes, comprising a workbench, a box body fixedly installed at one end of the workbench, a conveyor belt installed on the top of the workbench, anti-slip blocks spaced apart on the surface of the conveyor belt, and a crushing mechanism at the output end of the conveyor belt; a crushing box in the crushing mechanism is fixedly installed on the top of the box body, and two crushing rollers with crushing blades on their outer surfaces are rotatably connected inside the crushing box; a hammering mechanism is provided on the upper part of the crushing box, and the hammer in the hammering mechanism is located directly above the feed inlet and is reciprocatingly connected up and down; a screening mechanism is provided inside the crushing box, and a screen plate in the screening mechanism is horizontally arranged inside the crushing box and located directly below the crushing box, and a vibration motor is connected to the side wall of the screen plate; a cleaning mechanism is provided inside the box body.

[0007] Preferably, an outwardly protruding striking block is fixedly installed on the bottom surface of the striking hammer, and the top of the baffle is higher than the highest position of the bottom of the striking hammer.

[0008] Preferably, the motor of the crushing mechanism is fixedly installed outside the crushing box, the output shaft of the motor is fixedly connected to the rotating rod, the two crushing rollers are arranged in parallel, the two rotating rods are connected by belt drive, and the multiple sets of crushing blades on the two crushing rollers are arranged in a staggered manner between the two crushing rollers.

[0009] Preferably, a plurality of the crushing blades are fixedly mounted with cleaning blocks, which continuously sweep across the upper surface of the screen plate as the crushing roller rotates.

[0010] Preferably, multiple cutters are fixedly installed on the inner side of the crushing box, with the blades of the multiple cutters facing downwards. Sharpening plates are installed on both sides of the inner side of the crushing box, and the two sharpening plates are always in close contact with the multiple crushing cutters.

[0011] Preferably, the outer sidewall of the sieve plate is recessed inward with an installation groove, the vibration motor is integrally embedded and fixed inside the installation groove, and the upper surface of the sieve plate is evenly provided with a plurality of mesh holes that extend to the bottom surface.

[0012] Preferably, a mounting plate is horizontally fixed to the top of the box, and multiple motors are fixedly connected to the bottom of the mounting plate. Each of the output ends of the multiple motors is fixedly connected to a stirring structure.

[0013] Preferably, movable rods are fixedly connected to both sides of the inside of the box, and cleaning brushes are arranged at intervals along the circumferential and axial directions on the cylindrical outer walls of the two movable rods, with the bristles of the cleaning brushes protruding outwards.

[0014] Preferably, a curtain is horizontally fixedly laid inside the box, and multiple telescopic columns are fixedly installed at the bottom of the box. The multiple telescopic columns are arranged in an array and their output ends are fixedly connected to a fixing plate. The curtain is connected to the top surface of the multiple telescopic columns through the fixing plate.

[0015] This invention provides a device for the reuse and recycling of plastic packaging boxes. It has the following beneficial effects:

[0016] 1. This invention addresses the technical problem that large-volume hollow plastic packaging boxes cannot directly enter the meshing gap of the double rollers by setting a hammer driven by a motor, a rotating rod mechanism, and a telescopic rod directly above the feed inlet of the crushing box, and fixing an outwardly protruding hammer block at the bottom of the hammer. The vertical linear reciprocating motion of the hammer block applies periodic mechanical impact to the surface of the plastic packaging box, causing the packaging box to physically break and compress its volume before contacting the crushing rollers. At the same time, a baffle higher than the highest point of the bottom of the hammer forms a closed rigid barrier surface in space, which prevents material fragments ejected by external force from splashing into the outer space.

[0017] 2. This invention addresses the technical problem of physical blockage of crushed plastic particles at the screen mesh by fixing cleaning blocks to the outer end faces of multiple crushing blades inside the crushing chamber and setting the lowest point edge dimension of the cleaning block's rotational trajectory to always pass over the upper surface of the screen plate. The periodic mechanical scraping action generated by the cleaning blocks rotating with the crushing roller applies lateral shear force to the material accumulated on the screen plate surface, forcing the material to undergo horizontal displacement. Combined with the high-frequency excitation force output by the vibration motor, the physical throughput of material smaller than the inner diameter of the screen mesh is maintained by gravity through the mesh.

[0018] 3. This invention addresses the technical problem of separating solid plastic fragments from liquid cleaning water by fixing a cleaning brush with inwardly protruding bristles to the inner side wall of the box and installing a permeable curtain driven to rise and fall by multiple telescopic columns arranged in an array at the bottom of the box. When the water carries the material in a cyclical motion, the stationary cleaning brush applies relative sliding friction to the surface of the moving material to peel off the attached substances. Subsequently, by driving multiple telescopic columns to make a vertically upward linear extension motion simultaneously, the curtain is lifted as a whole over the liquid surface inside the box, and gravity causes the liquid to flow back downward through the curtain's pores, achieving effective cleaning of the broken materials.

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see the appendix Figure 1 -Appendix Figure 8This invention provides a recycling and processing device for plastic packaging boxes, including a workbench 1, a box body 4 fixedly installed at one end of the workbench 1, a conveyor belt 2 installed on the top of the workbench 1, anti-slip blocks 3 spaced apart on the surface of the conveyor belt 2, and a crushing mechanism 5 installed at the output end of the conveyor belt 2; a crushing box 501 in the crushing mechanism 5 is fixedly installed on the top of the box body 4, and two crushing rollers 503 with crushing blades 504 on their outer surfaces are rotatably connected inside the crushing box 501; a hammering mechanism 6 is installed on the upper part of the crushing box 501, and the hammers 606 in the hammering mechanism 6 are located directly above the feed inlet and are connected to move up and down reciprocally; a screening mechanism 7 is installed inside the crushing box 501, and the screen plate 701 in the screening mechanism 7 is horizontally installed inside the crushing box 501 and located directly below the crushing box 501, and a vibration motor 703 is connected to the side wall of the screen plate 701; a cleaning mechanism 8 is installed inside the box body 4;

[0030] Specifically, this device includes a workbench 1, a housing 4, a crushing mechanism 5, a hammering mechanism 6, a screening mechanism 7, and a cleaning mechanism 8. One end of the workbench 1 is fixedly connected to the housing 4. Inside the housing 4, the crushing mechanism 5, the screening mechanism 7, and the cleaning mechanism 8 are arranged vertically from top to bottom. A conveyor belt 2 is laid flat on the top of the workbench 1. The outer surface of the conveyor belt 2 is fixedly provided with upwardly protruding anti-slip blocks 3 at intervals along the conveying direction. When the conveyor belt 2 is in operation, the anti-slip blocks 3 move linearly synchronously with the belt. The protruding surface of the anti-slip blocks 3 makes physical contact with the plastic packaging boxes placed on them, increasing the friction parameters between the two material interfaces and conveying the plastic packaging boxes horizontally to the output end of the conveyor belt 2. The output end of the conveyor belt 2 extends spatially to the feed inlet side of the crushing box 501 fixed to the top of the housing 4. After the plastic packaging boxes leave the conveyor belt 2, they fall vertically downward under the action of gravity and enter the feed inlet.

[0031] See appendix Figure 5 The hammering mechanism 6 includes a rotating rod 601 rotatably connected to one side of the upper part of the crushing box 501. A baffle 602 is fixedly installed on the upper part of the rotating rod 601. A rotating rod 603 is rotatably connected to one side of the baffle 602. A motor 604 is fixedly connected to one end of the rotating rod 603. The rotating rod 603 is hinged to the telescopic rod 605 through the rotating rod 601. The output end of the telescopic rod 605 is fixedly connected to the top of the hammer 606.

[0032] Specifically, a hammering mechanism 6 is installed directly above the feed inlet of the crushing box 501. The output shaft of motor 2 604 transmits rotational torque to rotor 3 603 through a fixed connector. Rotor 3 603 is connected to one side of baffle 602 via a rotating bearing. The end of rotor 3 603 forms a mechanical hinge structure with telescopic rod 605 through rotor 2 601. When motor 2 604 operates, its output circular rotational motion is converted into linear reciprocating motion of telescopic rod 605 along the vertical Z-axis direction through the aforementioned linkage mechanism. The output end of telescopic rod 605 is fixedly connected to a hammer 606, driving the hammer 606 to perform synchronous vertical lifting and lowering motion in the feed inlet area.

[0033] A protruding striking block 607 is fixedly installed on the bottom surface of the striking hammer 606, and the top of the baffle 602 is higher than the highest point of the bottom of the striking hammer 606.

[0034] Specifically, the bottom working surface of the hammer 606 is fitted with an outwardly protruding striking block 607 by welding or bolt fastening. When the hammer 606 makes a downward linear displacement, the protruding end face of the striking block 607 makes a rigid collision with the plastic packaging box at the feed inlet. Compared with the flat end face, the protruding striking block 607 has a smaller contact area at the moment of collision, generating a relatively larger local pressure, which causes the plastic packaging box to undergo physical deformation or cracking. At the same time, the top physical height of the baffle 602 installed around the feed inlet is greater than the highest point of the hammer 606's movement stroke, thus forming a closed barrier in space to prevent material fragments splashed by the reaction force during the collision from crossing the feed inlet boundary.

[0035] See appendix Figure 4 The motor 505 of the crushing mechanism 5 is fixedly installed outside the crushing box 501. The output shaft of the motor 505 is fixedly connected to the rotating rod 502. The two crushing rollers 503 are arranged in parallel to each other. The two rotating rods 502 are connected by a belt 507. Multiple sets of crushing blades 504 on the two crushing rollers 503 are arranged in an interlaced manner between the two crushing rollers 503.

[0036] Specifically, the material deformed by hammering falls into the crushing chamber 501. The output shaft of the motor 505, fixed outside the crushing chamber 501, is rigidly connected to the rotating rod 502. The two rotating rods 502 are synchronously driven by the belt 507 sleeved on the outside. The belt 507 transmits torque to two crushing rollers 503 arranged in parallel inside the crushing chamber 501, driving the two crushing rollers 503 to rotate in opposite directions. Each of the two crushing rollers 503 has multiple sets of crushing blades 504 fixed circumferentially on its cylindrical outer wall. The crushing blades 504 on the first crushing roller 503 and the crushing blades 504 on the second crushing roller 503 are spatially staggered. When the crushing rollers 503 rotate in opposite directions, a mechanical shearing gap is formed between the two sets of staggered crushing blades 504. The material falling into this gap is subjected to the squeezing and tensile stress of the blades, causing physical fracture and being crushed into discrete fragments.

[0037] A cleaning block 506 is fixedly installed on a plurality of the crushing blades 504. The cleaning block 506 rotates with the crushing roller 503 and continuously sweeps across the upper surface of the screen plate 701.

[0038] Specifically, a cleaning block 506 is fixedly installed on the side or bottom end face of some of the crushing blades 504 using fasteners. The cleaning block 506 moves in a circular motion with the rotation of the crushing roller 503. At the lowest point of the movement trajectory, the outer edge dimension of the cleaning block 506 is set to produce a mechanical interference fit or zero clearance contact with the upper surface of the screen plate 701 located below it. Each time the cleaning block 506 rotates to the bottom, its edge sweeps across the upper surface of the screen plate 701, producing a physical scraping action, applying a lateral shearing force to the material attached to or stuck on the surface of the screen plate 701, forcing the material to undergo horizontal displacement.

[0039] Multiple cutters 508 are fixedly installed inside the crushing box 501, with the blades of the multiple cutters 508 facing downwards. Sharpening plates 509 are installed on both sides inside the crushing box 501, and the two sharpening plates 509 are always in contact with the multiple crushing cutters 504.

[0040] Specifically, multiple cutters 508 are statically fixed on the side wall inside the crushing box 501. The blades of the cutters 508 are straight or serrated and face vertically downward. Before the material falling from the feed inlet contacts the rotating crushing roller 503, it first contacts and is cut by the blades of the static cutters 508 due to gravity. In addition, two grinding plates 509 are symmetrically fixed on both sides inside the crushing box 501. The inner working surface of the grinding plate 509 is in close contact with the side wall of the multiple crushing blades 504 in the rotating state. The two continuously slide against each other during the operation of the equipment.

[0041] See appendix Figure 6The screen plate 701 has an inwardly recessed mounting groove 702 on its outer sidewall. The vibration motor 703 is integrally embedded and fixed inside the mounting groove 702. The upper surface of the screen plate 701 has a plurality of mesh holes that extend to the bottom surface.

[0042] Specifically, the screen plate 701 is horizontally suspended in the middle area inside the housing 4. The outer geometric sidewall of the screen plate 701 is recessed towards the center line to form a mounting groove 702. The housing of the vibration motor 703 is embedded in the mounting groove 702 and fixed with bolts. When the vibration motor 703 starts, the excitation force generated is transmitted to the structure of the screen plate 701 in the form of mechanical waves, causing the screen plate 701 to undergo high-frequency micro-amplitude three-dimensional vibration. The main surface of the screen plate 701 has mesh holes that penetrate through the upper and lower surfaces evenly distributed through the punching process. Under the combined action of gravity and the throwing acceleration generated by the high-frequency vibration of the screen plate 701, the crushed material with a geometric particle size smaller than the physical diameter of the mesh hole falls down through the mesh hole, while the material with a particle size larger than the diameter of the mesh hole is rigidly blocked above the screen plate 701.

[0043] See appendix Figure 7 The top of the box 4 is horizontally fixed with an installation plate 801, and the bottom of the installation plate 801 is fixedly connected with multiple motors 802. The output ends of the multiple motors 802 are all fixedly connected with a stirring structure 803.

[0044] Specifically, qualified materials falling through the mesh of the sieve plate 701 fall into the cleaning mechanism 8 at the bottom of the box 4. The top outer side of the box 4 is horizontally welded or bolted with an installation plate 801. Multiple motors 802 are fixedly installed with the bottom end face of the installation plate 801 facing downwards. The output shaft of the motors 802 passes downwards through the box 4 and is rigidly connected to the main shaft of the stirring structure 803 located in the liquid inside the box 4. The motors 802 output rotational kinetic energy to drive the stirring structure 803 to rotate in the liquid medium. Its blades stir the liquid to generate hydrodynamic vortices. The water flow carries the suspended crushed material to make irregular rolling and circulating displacement in the confined space at the bottom of the box 4.

[0045] Movable rods 804 are fixedly connected to both sides of the inside of the box 4. Cleaning brushes 805 are arranged and installed at intervals along the circumferential and axial directions on the cylindrical outer walls of the two movable rods 804. The bristles of the cleaning brushes 805 protrude outwards.

[0046] Specifically, two movable rods 804 are vertically fixed to the inner walls of both sides of the inner cavity of the box 4 by welding parts. The movable rods 804 are in a state of absolute stillness in space. On the cylindrical outer wall surface of the two movable rods 804, cleaning brushes 805 are fixed along the circumference of the cylinder 360 degrees and the axis. The ends of the bristles of the cleaning brushes 805 extend radially toward the central area of ​​the box 4. When the liquid inside the box 4 is driven by the stirring structure 803 and carries the crushed material to swirl along the inner wall of the box 4, the material in motion collides and slides relative to the bristles of the cleaning brushes 805 in a stationary state. The frictional shear force at the tip of the bristles acts on the surface of the material to peel off the attached impurities on its surface.

[0047] See appendix Figure 8 Inside the housing 4, a curtain 806 is laid horizontally and fixedly. Multiple telescopic columns 807 are fixedly installed at the bottom inside the housing 4. The multiple telescopic columns 807 are arranged in an array and their output ends are fixedly connected to a fixing plate 808. The curtain 806 is connected to the top surface of the multiple telescopic columns 807 through the fixing plate 808.

[0048] Specifically, multiple hydraulically or pneumatically driven telescopic columns 807 are fixedly installed in the absolute bottom area inside the housing 4. These telescopic columns 807 are arranged in a two-dimensional matrix array. The vertical output end of each telescopic column 807 is connected to a common horizontal fixed plate 808. A horizontally laid curtain 806 is placed inside the housing 4, with its lower surface supported above and connected to the fixed plate 808. When the cleaning process is terminated, the hydraulic or pneumatic control system drives the multiple telescopic columns 807 to extend linearly upwards in sync. The fixed plate 808 then moves vertically upwards, pushing the curtain 806 above it upwards. The curtain 806 is a woven material with microporous physical properties. When the vertical height of the curtain 806 exceeds the liquid level inside the housing 4, the liquid inside the housing 4 flows downwards through the micropores of the curtain 806 under its own gravity. Solid pulverized materials larger than the diameter of the micropores are physically trapped and supported on the upper surface of the curtain 806.

[0049] Working principle: First, place the plastic packaging box to be processed on the conveyor belt 2 at the top of the workbench 1. Start the conveyor belt 2, and the anti-slip blocks 3 on the surface of the conveyor belt 2 move synchronously with the conveyor belt 2 and make physical contact with the bottom surface of the plastic packaging box. The conveyor belt 2 continuously moves the plastic packaging box backward along the conveying direction until the plastic packaging box passes the output end of the conveyor belt 2 and falls into the feed port of the crushing mechanism 5 at the top of the box body 4 fixed at one end of the workbench 1 under the action of gravity.

[0050] When the plastic packaging box enters the feed inlet area, the motor 604 in the hammering mechanism 6 located on the upper part of the crushing box 501 is energized. The output end of the motor 604 drives the fixed rotating rod 603 to rotate. The rotating rod 603, connected to the rotating rod 601 via the baffle 602, converts the circular motion into the linear reciprocating motion of the telescopic rod 605 in the vertical direction. The output end of the telescopic rod 605 then drives the hammer 606, which is fixedly connected to its top, and the outwardly protruding striking block 607 fixedly installed on the bottom surface of the hammer 606, to reciprocate up and down directly above the feed inlet. When the striking block 607 moves downward, it periodically impacts the surface of the plastic packaging box, compressing and deforming the plastic packaging box. During the impact, the baffle 602, which is higher than the highest point of the bottom of the hammer 606, physically blocks the material fragments ejected by external force. After being deformed by the impact of the striking block 607, the material falls downward into the internal cavity of the crushing box 501 under gravity. During the material falling stage, it first undergoes mechanical cutting with multiple downward-facing cutters 508 fixedly installed inside the crushing box 501, and then contacts the crushing roller 503 below.

[0051] At this time, the motor 505, fixedly installed outside the crushing box 501, operates, and its output shaft drives the rotating rod 502 to rotate. The two rotating rods 502 are connected by a belt 507, driving the two parallel crushing rollers 503 to rotate relative to each other. Multiple crushing blades 504, arranged in an alternating pattern on the two crushing rollers 503, rotate accordingly, mechanically engaging and physically tearing the material. During the rotation of the crushing blades 504, the two grinding plates 509 on both sides inside the crushing box 501 remain in close contact with the surfaces of the multiple crushing blades 504. Simultaneously, the cleaning brush blocks 506, fixedly installed on the multiple crushing blades 504, rotate synchronously, and the outermost edge of the cleaning brush blocks 506 continuously scrapes across the upper surface of the screen plate 701 of the screening mechanism 7, generating a physical scraping action. The vibration motor 703, embedded in the mounting groove 702 on the side wall of the screen plate 701, drives the entire screen plate 701 to vibrate mechanically. Material crushed by the crusher blade 504 and whose volume is smaller than the mesh size of the sieve plate 701 passes through the mesh holes that extend to the bottom surface under the action of vibration and gravity, and falls into the cleaning mechanism 8 inside the box 4.

[0052] Multiple motors 802 fixed to the bottom of the mounting plate 801 on the top of the housing 4 operate, and their output ends drive the stirring structure 803 to rotate in the liquid inside the housing 4. When the crushed material moves with the water flow in the liquid, it makes physical contact and friction with the cleaning brushes 805 and their outward protruding bristles, which are arranged circumferentially and axially on the outer wall of the two movable rods 804 fixedly connected to both sides inside the housing 4, thus scraping off the adhering substances on the surface of the material. Subsequently, multiple telescopic columns 807 fixedly installed in an array at the bottom inside the housing 4 simultaneously extend linearly upward in the vertical direction. The output ends of the telescopic columns 807 push the fixed plate 808 fixedly connected to them upward, and the fixed plate 808 drives the horizontally laid curtain 806 to rise as a whole. The curtain 806 moves upward to contact and support the crushed material above it.
