Description

Technical Field

[0001] This invention mainly relates to the technical field of waste cable plastic recycling and processing equipment, specifically a special granular cleaning equipment for recycled cables based on waste cable plastic sheathing. Background Technology

[0002] The crushing and washing of waste cable plastic sheaths is the core pretreatment process for the preparation of recycled cable granules. In existing technologies, this process is generally completed by an integrated equipment that combines a crusher and a washing machine. The soft strip-shaped cable plastic sheaths are crushed by the relatively rotating crushing blade shaft inside the crusher. The crushed material falls directly into the washing machine below, where the rinsing components remove impurities and clean the material. The whole process forms a continuous "crushing-washing" operation. This type of equipment is widely used in the field of waste plastic recycling pretreatment due to its compact process connection.

[0003] The existing integrated equipment's methods for dealing with the problem of material entanglement on the crusher blades are extremely outdated, becoming a core pain point restricting the efficiency of recycling pretreatment operations. Due to the strong toughness and easy adhesion of cable plastic sheaths, materials easily become entangled on the surface of the crusher blades and gradually tighten around the blade shaft during the high-speed rotation and shearing process. However, existing equipment lacks any automatic detection and untangling structure design. The industry generally uses manual cleaning after stopping the machine to deal with the entanglement problem, which not only interrupts the continuous "crushing-cleaning" process, significantly reducing the overall pretreatment efficiency, but also increases the safety risks and labor costs of manual operation. At the same time, most existing crusher blades are fixed structures, and some simple telescopic crusher blades lack a working area locking design. During the cutting process, they are prone to retraction due to material resistance, which reduces cutting rigidity and crushing effect, and further aggravates material entanglement, forming a vicious cycle of "entanglement-low efficiency-more entanglement," failing to meet the continuous and efficient process requirements of recycled cable granules for raw material pretreatment. Summary of the Invention

[0004] The present invention addresses the problem of overly simplistic solutions in existing technologies by providing a significantly different solution. It primarily offers a specialized particle cleaning device for recycled cables based on waste cable plastic sheathing, thereby resolving the technical problem mentioned in the background section where existing crushing equipment struggles to handle blade entanglement when crushing recycled cable plastic sheathing.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows:

[0006] A special granular cleaning device for recycled cables based on waste cable plastic sheathing includes a cleaning machine and a crusher installed above the cleaning machine. The crusher has crushing components and auxiliary components on both sides inside for crushing the recycled cable plastic sheathing. The crushing components detect the degree of plastic sheath wrapping around the crushing blades. The cleaning machine is equipped with a rinsing component for washing the crushed plastic sheathing, and the rinsing component is also used to remove the plastic sheath wrapping around the crushing blades. The auxiliary components are equipped with a cutting component for cutting the plastic sheath wrapping around the crushing blades.

[0007] Preferably, the crusher is provided with a limiting block and a support block inside. The inner cavity of the support block is filled with hydraulic oil, and a first insert rod is inserted into a hole on one side of the inner cavity of the support block. A reset spring is sleeved on the first insert rod, and a detection plate is provided at the end of the first insert rod away from the inner cavity.

[0008] Preferably, the crushing component includes crushing blades, which are arranged in a circumferential array on a support shaft inside the crusher, and a first telescopic sleeve and a second telescopic sleeve are provided between the crushing blades and the support shaft.

[0009] Preferably, a first support spring and a second support spring are sleeved on the first telescopic sleeve rod and the second telescopic sleeve rod, the first support spring and the second support spring are separated by a partition plate, and a third support spring is sleeved on the second telescopic sleeve rod.

[0010] Preferably, the upper half of the inner cavity of the crusher is fixedly provided with a magnetic attraction part, and the back of the crushing blade is provided with a magnetically conductive mating part that cooperates with the magnetic attraction part.

[0011] Preferably, the flushing assembly includes a fixing block disposed inside the crusher, and a high-pressure nozzle is rotatably connected to the fixing block.

[0012] Preferably, the flushing assembly further includes a second insert rod, which is inserted into an inner cavity hole on the other side of the support block. The second insert rod is fixedly installed on the lifting block, and a slider is slidably connected to the lifting block. The slider is hinged to one end of the high-pressure nozzle.

[0013] Preferably, the auxiliary component includes an auxiliary crushing wheel, a fourth insert rod is inserted into the inner cavity of the auxiliary crushing wheel, the auxiliary crushing wheel is connected to the first telescopic sleeve rod through a second connecting pipe, a third return spring is sleeved on the fourth insert rod, and a pressure plate is provided at the end of the fourth insert rod away from the inner cavity of the auxiliary crushing wheel.

[0014] Preferably, the cutting assembly includes a cutting blade, which is rotatably connected to the auxiliary crushing wheel via a rotating shaft. The rotating shaft is equipped with a flat gear, and the cutting blade has a gap corresponding to the gap on the auxiliary crushing wheel.

[0015] Preferably, the cutting assembly further includes a liquid storage tube disposed inside the gap of the auxiliary crushing wheel. The liquid storage tube is connected to the inner cavity of the second telescopic sleeve rod through a first connecting pipe. A third insert rod is inserted into the end of the liquid storage tube away from the first connecting pipe. A limiting rod is disposed inside the gap of the auxiliary crushing wheel. A telescopic rod is inserted into the limiting rod. The telescopic rod is connected to the third insert rod. A second return spring is sleeved on the telescopic rod. A rack is disposed at the end of the telescopic rod away from the limiting rod. The rack meshes with a spur gear.

[0016] Compared with existing technologies, the advantages of this invention are as follows: This invention achieves precise detection and graded automatic untangling of the degree of plastic sheath entanglement on the crusher blades, completely eliminating the traditional manual cleaning method that requires downtime in the industry. Through the cooperative structure of a three-stage support spring and a double telescopic sleeve, it can accurately identify the light, medium, and heavy degrees of plastic sheath entanglement on the crusher blades, and correspondingly realize targeted actions such as blade self-relaxation and unloading, high-pressure water flushing and unloading, and cutting blade untangling and unloading. It forms a fully closed-loop automatic processing for different blade entanglement conditions, greatly reducing the blade entanglement rate, fundamentally avoiding downtime caused by blade entanglement, ensuring continuous operation of the waste cable plastic sheath crushing and cleaning process, and significantly improving the overall efficiency of recycling pretreatment.

[0017] This invention, through an integrated design of magnetic locking and hydraulic linkage, balances the intensity of crushing operations with the coordinated automation of various components. The magnetic attraction part in the upper section of the crusher cooperates with the magnetically guided part on the back of the crushing blade, keeping the blade in an extended and locked state in the cutting area, effectively preventing retraction and ensuring cutting rigidity and crushing effect. When the blade rotates to the lower cleaning and untangling area, the magnetic force disappears, allowing it to extend and retract freely. Simultaneously, the extension and retraction of the crushing components is driven by hydraulic oil, synchronously linking the high-pressure nozzle angle adjustment of the flushing component and the rotation of the cutting blade of the cutting component. This achieves fully automated and coordinated operation of "crushing detection - blade entanglement triggering - cleaning / cutting untangling," eliminating the need for manual intervention. This reduces manual operation costs and safety risks, while making the response to untangling and unloading more timely and precise, significantly improving the automation level of the equipment.

[0035] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be given below with reference to the accompanying drawings, which illustrate several embodiments of the present invention. However, the present invention can be implemented in different forms and is not limited to the embodiments described in the text. Rather, these embodiments are provided to make the disclosure of the present invention more thorough and complete.

[0036] Please refer to the appendix carefully. Figures 1-9 A special granular cleaning equipment for recycled cables based on waste cable plastic sheathing includes a cleaning machine 1 and a crusher 2 installed above the cleaning machine 1. The crusher 2 has a crushing component 3 and an auxiliary component 6 installed on both sides inside for crushing the recycled cable plastic sheathing. The crushing component 3 detects the degree of plastic sheathing wrapped around the crushing blades 31 in the crushing component 3. The cleaning machine 1 is equipped with a rinsing component 4 for cleaning the crushed plastic sheathing. The rinsing component 4 is also used to remove the plastic sheathing wrapped around the crushing blades 31. The auxiliary component 6 is equipped with a cutting component 5 for cutting the plastic sheathing wrapped around the crushing blades 31.

[0037] The specific operation process of this invention is as follows: The recycled waste cable is placed inside the crusher 2. The crushing components 3, rotating relative to each other on both sides inside the crusher 2, crush the cable's plastic sheath. The crushed cable sheath falls into the cleaning machine 1 below. The washing component 4, in conjunction with the built-in cleaning structure of the cleaning machine 1, removes impurities from the cable's plastic sheath. Some plastic sheath is not crushed by the crushing component 3 and instead becomes entangled above the crushing blade 31. The crushing component 3 detects the degree of entanglement. When the entanglement is low, the crushing component 3 rotates downwards, and the crushing blade 31 slightly retracts, allowing the plastic sheath entangled above the crushing blade 31 to loosen and fall off. When the plastic sheath entangled on the crushing blade 31 is tight, the crushing blade 31 retracts more when rotating downwards. At this time, the crushing component 3 controls the washing component 4 to spray water upwards, spraying water onto the crushing blade 31. The crusher 31 loosens the plastic sheet by contracting its blades, and the water source washes it off. When the plastic sheet is tightly wrapped around the crusher 31, the crusher 31 rotates downwards, and at this time the crusher 31 is in its most compressed state. At this time, the crushing component 3 triggers the cutting component 5, which cuts the plastic sheet wrapped around the crusher 31, thus detaching the tightly wrapped plastic sheet. The top of the crusher 2 is equipped with an inclined feed guide plate to prevent material jamming. The bottom of the washing machine 1 is equipped with a discharge port with a filter screen to facilitate the collection of plastic particles and the discharge of wastewater after washing.

[0038] Please refer to Figures 4-9The crusher 2 is equipped with a limiting block 21 and a support block 22. The inner cavity of the support block 22 is filled with hydraulic oil, and a first insert rod 23 is inserted into a hole on one side of the inner cavity of the support block 22. A reset spring is sleeved on the first insert rod 23. A detection plate 25 is provided at the end of the first insert rod 23 away from the inner cavity. The crushing component 3 includes a crushing blade 31. The crushing blades 31 are arranged in a circumferential array on the support shaft inside the crusher 2. A first telescopic sleeve rod 32 and a second telescopic sleeve rod 33 are provided between the crushing blades 31 and the support shaft. A first support spring 35 and a second support spring 36 are sleeved on the first telescopic sleeve rod 32 and the second telescopic sleeve rod 33. The first support spring 35 and the second support spring 36 are separated by a partition plate 34. A third support spring 37 is sleeved on the second telescopic sleeve rod 33.

[0039] Both the first telescopic sleeve 32 and the second telescopic sleeve 33 are equipped with hydraulic oil. The hydraulic oil is compressed by the contraction of the first telescopic sleeve 32 and the second telescopic sleeve 33. When plastic skin is wrapped around the crusher blade 31, and the crusher blade 31 rotates to the lower half of the crusher 2's inner cavity, the crusher blade 31 will retract. The crusher blade 31 will compress different springs depending on the degree of plastic skin wrapping. When the wrapping force is small, only the first support spring 35 will retract, and only the first telescopic sleeve 32 in the front half of the partition plate 34 will retract. At this time, the hydraulic oil inside the first telescopic sleeve 32 will not be compressed. If the wrapping force is large, the crusher blade 31 will retract to a greater extent, and the first support spring... Both springs 35 and 36 are compressed, at which point the first telescopic sleeve 32 is fully retracted, and the hydraulic oil inside the first telescopic sleeve 32 is squeezed. When the plastic skin is wrapped at its tightest, the crusher 31 will retract to its maximum extent, compressing the first support spring 35, the second support spring 36, and the third support spring 37. At this point, both the first telescopic sleeve 32 and the second telescopic sleeve 33 are compressed, and the hydraulic oil inside both the first telescopic sleeve 32 and the second telescopic sleeve 33 is squeezed. Among them, the first support spring 35 has the smallest elastic coefficient, corresponding to the contraction stroke when the plastic skin is lightly wrapped; the third support spring 37 has the largest elastic coefficient, and compression only occurs when the plastic skin is heavily wrapped.

[0040] Please refer to Figure 3 The upper part of the inner cavity of the crusher 2 is fixedly provided with a magnetic attraction part, and the back of the crusher blade 31 is provided with a magnetically conductive mating part that cooperates with the magnetic attraction part.

[0041] The upper 180° circumference of the inner cavity of crusher 2 is the magnetic attraction zone for crushing operations, and the lower 180° circumference is the non-magnetic zone for untangling operations. A magnetic attraction part is fixedly installed in the upper half of the inner cavity of crusher 2 corresponding to the crushing operation area. The magnetic attraction part is a permanent magnet or an electromagnetic adsorption structure. A magnetically conductive mating part is provided on the back of the crushing blade 31. This magnetically conductive mating part is made of a magnetically conductive material and is non-magnetic. When the crushing blade 31 rotates with the cutter shaft to the upper half of the crushing area of ​​crusher 2, the crushing blade 31 maintains a radially extended state under the attraction of the magnetic attraction part, limiting the radial contraction of the crushing blade 31 and ensuring cutting rigidity during crushing operations. When the blade continues to rotate to the lower cleaning and untangling area, the blade leaves the range of the magnetic attraction part, the attraction disappears, and the crushing blade 31 can overcome the elastic force of the three-stage elastic element and radially contract under the force of material entanglement, thereby triggering the corresponding untangling action.

[0042] Please refer to Figure 8 The flushing assembly 4 includes a fixing block 41, which is disposed inside the crusher 2. A high-pressure nozzle 42 is rotatably connected to the fixing block 41. The flushing assembly 4 also includes a second insert rod 44, which is inserted into the inner cavity hole on the other side of the support block 22. The second insert rod 44 is fixedly installed on the lifting block 43. A slider 45 is slidably connected to the lifting block 43. The slider 45 is hinged to one end of the high-pressure nozzle 42.

[0043] When the detection plate 25 is pressed down, it will press down the first insertion rod 23 and the first reset spring 24. The first insertion rod 23 is inserted into one end of the inner cavity of the support block 22 and a piston is provided. The insertion of the first insertion rod 23 into one end of the inner cavity of the support block 22 increases the hydraulic oil in the inner cavity of the support block 22. The hydraulic oil inside the support block 22 is squeezed to the hole on the other side. The second insertion rod 44 is inserted into one end of the inner cavity of the support block 22 and a piston is also provided. The second insertion rod 44 is squeezed outward and pushes the lifting block 43 to move down. The lifting block 43 drives the rear end of the high pressure nozzle 42 to move down through the slider 45. With the rotatable connection between the high pressure nozzle 42 and the fixed block 41 as the axis, the water outlet of the high pressure nozzle 42 is lifted up. At this time, the water outlet of the high pressure nozzle 42 is raised and aligned with the upper crusher 31. A torsion spring is provided at the rotatable connection between the high pressure nozzle 42 and the fixed block 41 to drive the high pressure nozzle 42 to reset.

[0044] Please refer to Figures 4-9 The auxiliary component 6 includes an auxiliary crushing wheel 61, a fourth insert rod 62 is inserted into the inner cavity of the auxiliary crushing wheel 61, the auxiliary crushing wheel 61 is connected to the first telescopic sleeve rod 32 through a second connecting pipe 39, a third reset spring 63 is sleeved on the fourth insert rod 62, and a pressure plate 64 is provided at the end of the fourth insert rod 62 away from the inner cavity of the auxiliary crushing wheel 61.

[0045] When both the first support spring 35 and the second support spring 36 are compressed, the first telescopic sleeve 32 is in a fully retracted state. The hydraulic oil inside the first telescopic sleeve 32 is squeezed and transported through the second connecting pipe 39 into the inner cavity of the corresponding auxiliary crushing wheel 61. As the amount of hydraulic oil in the inner cavity of the auxiliary crushing wheel 61 increases, the fourth insert rod 62 is inserted into a piston at one end of the inner cavity of the auxiliary crushing wheel 61. The hydraulic oil pushes the fourth insert rod 62 upward, and the fourth insert rod 62 drives the pressure plate 64 upward. When the pressure plate 64 rotates above the detection plate 25, the pressure plate 64 will press down on the detection plate 25.

[0046] Please refer to Figures 4-9 The cutting assembly 5 includes a cutting blade 51, which is rotatably connected to the gap in the auxiliary crushing wheel 61 via a rotating shaft 52. A spur gear 53 is provided on the rotating shaft 52. The crushing blade 51 has a gap corresponding to the gap in the auxiliary crushing wheel 61. The cutting assembly 5 also includes a liquid storage pipe 59, which is located inside the gap in the auxiliary crushing wheel 61. The liquid storage pipe 59 is connected to the inner cavity of the second telescopic sleeve 33 via a first connecting pipe 38. A third insert rod 58 is inserted into the end of the liquid storage pipe 59 away from the first connecting pipe 38. A limiting rod 55 is provided inside the gap in the auxiliary crushing wheel 61. A telescopic rod 56 is inserted into the limiting rod 55. The telescopic rod 56 is connected to the third insert rod 58. A second return spring 57 is sleeved on the telescopic rod 56. A rack 54 is provided at the end of the telescopic rod 56 away from the limiting rod 55. The rack 54 meshes with the spur gear 53.

[0047] When the second telescopic sleeve 33 is compressed, the hydraulic oil inside the second telescopic sleeve 33 is squeezed and transported into the liquid storage pipe 59 through the first connecting pipe 38. The third insert rod 58 is inserted into the liquid storage pipe 59, and a piston is set at one end. The third insert rod 58 is squeezed down by the hydraulic oil. The third insert rod 58 pulls the rack 54 down through the telescopic rod 56. The rack 54 moves down and drives the spur gear 53 to rotate. The spur gear 53 drives the rotating shaft 52 to rotate. The rotating shaft 52 drives the cutting blade 51 to rotate. The cutting blade 51 rotates and inserts into the gap opened on the crusher 31 to cut the plastic skin wrapped on the crusher 31. The maximum rotation angle of the cutting blade 51 is 270°. The downward stroke of the rack 54 is limited by the limiting rod 55 to ensure that the cutting blade 51 is accurately inserted into the gap of the crusher 31 without collision.

[0048] After the plastic sheet on the breaker blade 31 falls off, the elastic force of the three-stage support spring pushes the telescopic sleeve rod to reset, the hydraulic oil flows back, and each insert rod, rack, and high-pressure nozzle returns to its initial state under the action of the reset spring / torsion spring.

[0049] The present invention has been described by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
