Description

Technical Field

[0001] This invention relates to the field of waste fabric recycling and granulation technology, specifically to a crushing device for granulating waste plastic fabric. Background Technology

[0002] Plastic waste fabric is a common industrial solid waste generated during the production and processing of plastic products. In order to achieve resource recycling and reduce solid waste pollution, the industry generally uses crushing and granulation equipment to recycle and reprocess plastic waste fabric, turning waste fabric into recycled granules, thus realizing the resource recycling and utilization of solid waste.

[0003] Currently, most existing plastic waste fabric crushing and granulation equipment adopts a single-pass direct crushing structure without a pre-cutting process. During the operation of the equipment, the input plastic waste fabric is directly crushed at high speed. However, in actual production, the plastic waste fabric to be processed is often of varying lengths. When a large number of long strips of waste fabric enter the crushing chamber directly, they cannot be crushed quickly and uniformly.

[0004] Long strips of waste fabric are easily entangled and wrapped around the blades and shaft under the action of high-speed rotating crushing blades. This not only causes blade jamming and increased load, leading to equipment stalling and shutdown, but also reduces equipment stability and service life. It increases equipment maintenance frequency and production costs, seriously affecting the continuity of plastic waste fabric recycling and granulation. Therefore, there is an urgent need for a crushing device that can solve the problem of long strips of waste fabric entanglement and achieve segmentation before crushing. Summary of the Invention

[0019] Compared with the prior art, the present invention provides a crushing device for granulating waste plastic fabric, which has the following beneficial effects:

[0020] 1. This equipment adopts a two-stage processing structure of first cutting into segments and then crushing. Relying on a support platform to provide delayed support for the falling waste fabric, it effectively extends the dwell time of long strips of waste fabric, ensuring that they are fully cut into shorter segments before entering the fine crushing process. This completely solves the defects of traditional equipment that directly crushes long strips of plastic waste fabric without cutting them into segments, easily causing the blades to entangle and jamming the equipment. It effectively improves crushing stability and material processing uniformity, avoids equipment jamming and stalling, and significantly improves the overall quality of plastic waste fabric crushing.

[0021] 2. By using airflow to gather scattered waste plastic fabric and precisely push it into the guide cylinder, the problem of lightweight waste fabric floating, accumulating, and being difficult to feed autonomously is solved. This structure enables automated continuous feeding and efficient crushing and granulation of industrial waste plastic fabric, significantly improving the resource recycling rate of waste plastic fabric, reducing environmental pollution caused by the indiscriminate disposal of plastic solid waste, and realizing the green circular recycling of industrial solid waste.

[0022] 3. Utilizing a high-pressure airflow adapted to the angle of the filter plate, the scattered, cut waste cloth is continuously gathered into the core crushing area, preventing the waste cloth from dispersing and shifting, which could lead to insufficient crushing. At the same time, the high-pressure airflow can propel and guide the finely crushed material, promoting the rapid passage of qualified particles through the screen. This not only significantly improves the uniformity of crushing but also effectively increases screening efficiency, reduces processing time, and enhances the overall continuous operation capacity of the equipment.

[0023] 4. Utilizing pneumatic pressure to drive the piston rod into the guide cylinder, and in conjunction with the overall lifting structure, forcibly pushes the accumulated material, effectively eliminating problems such as bridging, jamming, and blockage of waste fabric inside the guide cylinder. The structure can automatically reset and controllably start and stop, eliminating the need for manual shutdown to clear blockages, significantly reducing equipment failure rate and labor maintenance costs, ensuring long-term, uninterrupted continuous operation, and making it suitable for large-volume waste fabric crushing and processing scenarios.

The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0043] Example 1:

[0044] This embodiment discloses a crushing device for granulating waste plastic fabric. The main body of the device includes an outer shell, inside which a fixing plate 12 is fixedly installed. The cavity above the fixing plate 12 forms a storage cavity for storing the waste plastic fabric to be processed. Multiple guide cylinders 20 are fixedly installed at equal intervals along the circumference of the fixing plate 12. Each guide cylinder 20 has a corresponding fixing ring 21 at its bottom end. The guide cylinder 20 is fixedly connected to the fixing ring 21 at the corresponding position through a connecting frame 22, and a gap is reserved between the bottom end of the guide cylinder 20 and the fixing ring 21 for the cutting tool to pass through.

[0045] A first motor 30 is fixedly installed at the center of the fixed plate 12. A rod is fixedly assembled at the output end of the first motor 30. The rod consists of a first rod body 31 and a second rod body 34. The bottom end of the first rod body 31 is fixedly connected to the top end of the second rod body 34 to form an integrated structure. A first mounting base 32 is fixedly installed on the first rod body 31, and a cutting blade 33 is fixedly assembled on the first mounting base 32. During the rotation of the cutting blade 33, its end can penetrate the gap between the guide cylinder 20 and the fixed ring 21. Multiple crushing blades 35 are fixedly installed at the bottom end of the second rod body 34. The crushing blades 35 rotate synchronously with the rod at high speed to realize the fine crushing of waste cloth.

[0046] A filter plate 13 is fixedly installed inside the outer casing, below the fixing ring 21. The filter plate 13 is used to screen the crushed plastic waste cloth, intercept waste cloth that does not meet the size requirements, and ensure uniform particle size.

[0047] A first annular tube 42 is rotatably mounted on the top of the outer shell. Multiple jet pipes 43 are fixedly mounted at equal intervals along the circumference of the first annular tube 42. The bottom end of the jet pipes 43 extends into the storage cavity. A drive assembly is provided on the outer shell to drive the first annular tube 42 to rotate at low speed, thereby causing all the jet pipes 43 to move in a circular motion synchronously.

[0048] In this embodiment, a support platform 23 is provided directly below each fixed ring 21. The support platform 23 is fixedly connected to the corresponding guide cylinder 20, and a reserved gap is provided between the upper surface of the support platform 23 and the bottom end of the fixed ring 21. At the same time, a second mounting base 36 is fixedly installed on the first rod body 31. Multiple push rods 37 are fixedly installed at equal intervals in the circumferential direction of the second mounting base 36. The ends of the push rods 37 can pass over the upper surface of the support platform 23 during rotation. The support platform 23 can support the waste cloth falling into the guide cylinder 20, slow down the falling speed of the waste cloth, and allow the waste cloth to stay inside the guide cylinder 20 for a sufficient time. This ensures that the cutting blade 33 can fully cut the long strips of waste cloth into segments, effectively preventing the uncut complete waste cloth from falling directly onto the surface of the filter plate 13, and ensuring the integrity of the initial cutting process.

[0049] To optimize the flow of waste cloth inside the storage cavity, an inclined body 101 is fixedly installed inside the storage cavity and at the edge of the fixed plate 12. An inclined cover 102 is fixedly installed at the center of the upper surface of the fixed plate 12. The top of the guide cylinder 20 is located in the area between the bottom of the inclined body 101 and the bottom of the inclined cover 102. Through the flow guiding and limiting effect of the inclined body 101 and the inclined cover 102, the waste cloth in the storage cavity can be concentrated and gathered to the feeding area at the top of the guide cylinder 20.

[0050] In this embodiment, the bottom end of the jet pipe 43 is at the same horizontal level as the upper surface of the fixing plate 12. Each jet pipe 43 has an air passage inside, and the bottom end of the jet pipe 43 is an open structure. The air passage of the jet pipe 43 is interconnected with the interior of the first annular pipe 42. The equipment is equipped with an air supply assembly, which can continuously supply high-pressure air into the interior of the first annular pipe 42. At the same time, multiple jet branch pipes 431 are fixedly installed on the vertical section of the jet pipe 43, and the air outlet at the bottom end of each jet branch pipe 431 is inclined towards the vertical section of the jet pipe 43.

[0051] The specific working process of the device in this embodiment is as follows: The plastic waste cloth to be recycled and granulated is put into the storage cavity inside the outer shell. The drive component drives the first annular tube 42 to rotate at a low speed, which drives all the jet pipes 43 and jet branch pipes 431 to move in a synchronous circular motion. The high-pressure gas sprayed by the jet branch pipe 431 can gather the scattered waste cloth in the storage cavity towards the vertical part of the jet pipe 43. When the jet pipe 43 moves to the top position of the guide tube 20, the bottom end of the jet pipe 43 is released from the blocking state of the fixing plate 12, and the high-pressure gas is sprayed out from the bottom end of the jet pipe 43. With the gathering airflow of the jet branch pipe 431, the waste cloth attached to the jet pipe 43 is accurately pushed into the interior of the guide tube 20.

[0052] After the first motor 30 starts, it drives the first rod 31 and the second rod 34 to rotate at high speed, which in turn drives the cutting blade 33 and the crushing blade 35 to rotate synchronously at high speed. The long strip of waste cloth that enters the guide cylinder 20 is supported and limited by the support platform 23. The high-speed rotating cutting blade 33 passes through the gap between the guide cylinder 20 and the fixing ring 21 and cuts the long strip of waste cloth into short strips. After the waste cloth is cut, it is pushed off the support platform 23 by the push rod 37 and falls onto the surface of the filter plate 13 below. Then, the high-speed rotating crushing blade 35 further crushes the short strips of waste cloth to the specified particle size.

[0053] Example 2:

[0054] This embodiment is a further optimization of the basic structure of Embodiment 1. The outer shell of the device is composed of an upper shell 10 and a lower shell 11, and the upper shell 10 and the lower shell 11 are fixedly connected by multiple fixing blocks 111.

[0055] The filter plate 13 adopts an irregularly shaped structure with inclined edges and a horizontal bottom center, suitable for waste cloth diversion and centralized crushing operations. A second annular pipe 50 is rotatably mounted on the inner surface of the outer casing, located at the top edge of the filter plate 13. Multiple air jets 52 are fixedly mounted at equal intervals along the circumference of the second annular pipe 50. The air jets 52 are inclined, and their inclination angle perfectly matches the inclination angle of the inclined edge of the filter plate 13. The second annular pipe 50 is connected to the air supply assembly of the equipment, and it can rotate synchronously with the first annular pipe 42.

[0056] The air supply assembly in this embodiment includes an air pump 40 and a delivery pipe 41. An annular pipe is rotatably mounted on the outer surface of the outer casing. The annular pipe consists of an inner ring 47 and a pair of rotating rings 45. The two rotating rings 45 are fixedly connected by multiple connecting rods 451. The inner ring 47 is rotatably mounted inside the two rotating rings 45. The rotating rings 45 are fixedly connected to the first annular pipe 42 through multiple first connecting pipes 44, and to the second annular pipe 50 through multiple second connecting pipes 51. An outer ring 46 is rotatably mounted on the outer edge of the annular pipe. The air outlet of the air pump 40 is fixedly connected to the outer ring 46 through the delivery pipe 41. The high-pressure gas output by the air pump 40 can be introduced into the interior of the annular pipe through the delivery pipe 41 and the outer ring 46, and then diverted to the first annular pipe 42 and the second annular pipe 50 through the first connecting pipe 44 and the second connecting pipe 51, respectively, to achieve dual-path synchronous air supply.

[0057] The drive assembly in this embodiment includes a second motor 70, a gear ring 71, and a gear 72. The gear ring 71 is fixedly connected to the second annular tube 50 as an integral structure. The second motor 70 is fixedly mounted on the outer surface of the outer casing. The gear 72 is fixedly assembled at the output end of the second motor 70, and the gear 72 and the gear ring 71 are always in a meshed state. When the equipment is running, the second motor 70 drives the gear 72 to rotate, which in turn drives the gear ring 71 and the second annular tube 50 to rotate through gear meshing transmission. At the same time, relying on the pipeline linkage structure, the first annular tube 42 is driven to rotate synchronously, realizing synchronous and uniform operation of the two annular tubes.

[0058] The working principle of this embodiment is as follows: the short sections of waste cloth cut by the cutting blade 33 first fall onto the inclined surface of the filter plate 13. The jet nozzle 52, rotating synchronously with the second annular pipe 50, sprays high-pressure gas. Based on the adapted jet angle, the waste cloth on the inclined surface is continuously moved towards the horizontal part at the bottom of the filter plate 13. After the waste cloth is concentrated in the horizontal part, it is in the core processing area of ​​the crushing blade 35, facilitating efficient fine crushing by the crushing blade 35. During the crushing process, the high-pressure gas continuously sprayed by the jet nozzle 52 can, on the one hand, push the waste cloth to always adhere to the crushing operation area, avoiding waste cloth deviation and insufficient processing; on the other hand, it can guide and propel the finely crushed material, allowing the waste cloth fragments that meet the particle size requirements to pass through the filter plate 13 more smoothly, effectively improving material screening and processing efficiency.

[0059] Example 3:

[0060] The outer casing contains a third annular tube 60 that can be raised and lowered. Multiple piston tubes 61 are fixedly installed at equal intervals along the circumference of the third annular tube 60. A piston structure is slidably mounted inside each piston tube 61, and a piston rod 62 is fixedly connected to each piston. Each guide cylinder 20 corresponds to one or more piston rods 62, and the guide cylinder 20 has one or more channels 201 on its wall that are adapted to the size and position of the piston rod 62, allowing the piston rod 62 to penetrate and insert into the guide cylinder 20. A tension spring 63 is fixedly installed between the piston and the bottom inner side of the piston tube 61. The tension spring 63 can automatically reset the piston and piston rod 62 after the air pressure is released.

[0061] A rigid tube 65 is fixedly connected to the inner ring 47. A control valve 651 is fixedly mounted on the body of the rigid tube 65. The end of the rigid tube 65 is fixedly connected to the internal cavity of the third annular tube 60 through a flexible tube 66, so as to realize the controllable delivery of high-pressure gas. A pressure relief head 67 is fixedly installed on the outside of the third annular tube 60. A pressure relief valve 671 is installed on the pressure relief head 67 to realize the pressure relief and regulation of the gas pressure inside the third annular tube 60, so as to ensure the safe operation of the structure.

[0062] To achieve stable lifting and lowering adjustment of the third annular tube 60, an electric telescopic rod 64 is fixedly installed inside the outer casing. The movable end of the electric telescopic rod 64 is fixedly connected to the third annular tube 60. Through the extension and retraction of the electric telescopic rod 64, the entire third annular tube 60 can be precisely driven to move up and down, thereby driving all piston rods 62 to move synchronously.

[0063] The working process of this embodiment is as follows: During normal crushing operation, the control valve 651 on the rigid pipe 65 is opened, and the high-pressure gas stored inside the rotating ring 45 is introduced into the third annular pipe 60 through the rigid pipe 65 and the hose 66, and then diverted into the interior of each piston pipe 61. The high-pressure gas pushes the piston to slide and displace against the elastic force of the tension spring 63, driving the piston rod 62 to pass through the channel 201 and insert into the internal cavity of the guide cylinder 20.

[0064] At this time, the movable end of the control electric telescopic rod 64 extends outward, pushing the third annular tube 60 to move downward as a whole. Simultaneously, the piston rod 62 inserted into the guide tube 20 moves downward. The piston rod 62 inserts into the waste cloth material inside the guide tube 20, pushing the accumulated waste cloth downward. This forces the stuck and accumulated waste cloth inside the guide tube 20 to be pushed to the bottom gap position, completely solving the problem of waste cloth bridging and blockage, and ensuring continuous material falling for processing.

[0065] After a single anti-blocking operation is completed, the control valve 651 can be closed and the pressure relief valve 671 on the pressure relief head 67 can be opened to release the high-pressure gas inside the third annular tube 60 and the piston tube 61. Under the elastic reset action of the tension spring 63, the piston slides in the opposite direction, driving the piston rod 62 out of the guide cylinder 20 and back to the initial position. At the same time, the electric telescopic rod 64 retracts, driving the third annular tube 60 to reset, thus completing one anti-blocking cleaning operation. The equipment can continue to operate in a cycle.

Those skilled in the art can readily implement the present invention based on the accompanying drawings and the above description.
