Description

Technical Field

[0001] This utility model relates to the field of fabric production technology, and in particular to a PE fabric scrap recycling and crushing device. Background Technology

[0002] PE fabric scraps are irregular edges, broken pieces, and other waste generated during the production and processing of polyethylene woven fabric that cannot be directly used in the production of finished products. The reason why recycling and crushing equipment is necessary is that polyethylene, the main component of PE fabric, is recyclable. This equipment can crush the scraps into uniform particles, realize resource reuse, reduce dependence on virgin resin, lower costs, and avoid "white pollution" caused by the non-degradability of polyethylene, which meets environmental protection policy requirements. It can also reduce the volume of scraps to lower transportation and storage costs, facilitate subsequent processing, and can be automated and continuously processed to match the pace of large-scale production, avoiding the accumulation of scraps. It is an important link in saving resources and protecting the environment in the plastic circular economy.

[0003] A search revealed that the document with publication number "CN215885304U" mentions "This utility model discloses a non-woven fabric scrap recycling device, including a conveyor frame, a support frame, a crushing box, a discharge pipe, and a hopper. The conveyor frame is mounted on the support frame, and belt rollers are arranged on both sides of the support frame. A conveyor belt is arranged between the belt rollers. A motor II is arranged on the left side of the front side of the conveyor frame, and the output shaft of the motor II passes through the inside of the conveyor frame and connects to the belt rollers. A protective cover is provided on the conveyor frame, and an ultraviolet disinfection lamp is arranged on the inner top surface of the protective cover. An outer surface of the ultraviolet disinfection lamp is provided with..." The protective netting includes a hopper positioned above the left end of the conveyor frame, a protective cover connected to the crushing box at its right end, and a discharge pipe connected to the lower end of the crushing box. This utility model features a reasonable structural design, convenient feeding, labor-saving operation, and excellent crushing effect. It protects the non-woven fabric, reduces external environmental pollution, and disinfects the non-woven fabric during feeding.

[0004] However, PE fabric is thin and light, and its scraps are usually loose, with a large volume but low density. If they are directly fed into the crushing mechanism, the material will be unevenly distributed in the crushing box, with too much material in some areas and too little material in others. This will affect the force balance of the crushing blades and reduce the crushing efficiency. At the same time, the existing crushing and recycling devices are not flexible in adjusting the crushing particle size and cannot meet the diverse production needs.

[0005] Therefore, we provide a PE fabric scrap recycling and crushing device to solve the above problems. Utility Model Content

[0006] To overcome the above deficiencies, this utility model provides a PE fabric scrap recycling and crushing device, which aims to solve the problems mentioned above.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A PE fabric scrap recycling and crushing device includes a flow guide chamber. A pre-extrusion assembly is fixedly connected to the upper end of the flow guide chamber. The pre-extrusion assembly includes an extrusion chamber fixedly connected to the upper end of the flow guide chamber. An extrusion roller is rotatably connected to the inner side of the extrusion chamber. A crushing chamber is welded to the lower end of the flow guide chamber. A groove is formed on the front surface of the crushing chamber. A fixing plate is provided below the groove. A slide rail is installed on the surface of the fixing plate. A sliding motor is slidably connected to the surface of the slide rail. An adjusting assembly is connected to one end of the sliding motor with a flat key. The adjusting assembly includes a connecting chamber connected to one end of the sliding motor with a flat key. A telescopic sleeve is fixedly connected to the right side of the connecting chamber.

[0008] As a further description of the above technical solution: The crushing chamber is welded to the fixed plate, the slide rail is fixedly connected to the surface of the fixed plate by bolts, and the sliding motor is slidably connected to the slide rail through the sliding base.

[0009] As a further description of the above technical solution: There are two extrusion rollers, which are arranged parallel to each other. A sleeve is fixedly connected to the left end of each extrusion roller. A belt is fitted onto the surface of the sleeve. A drive motor is connected to the inner side of the sleeve. The drive motor drives the belt to transmit power through the sleeve.

[0010] As a further description of the above technical solution: The telescopic sleeve has a telescopic rod on its inner side. A buffer spring is sleeved on the surface of the telescopic rod, and the right end of the buffer spring abuts against the left end of the telescopic sleeve. The telescopic rod has a threaded rod on its inner side, and the right end of the threaded rod has a hexagonal groove. The threaded rod passes through the telescopic rod and the telescopic sleeve and is threadedly connected to the connecting chamber.

[0011] As a further description of the above technical solution: An adjustable crushing roller is provided on the inner side of the crushing chamber, and a fixed crushing roller is provided on the left side of the adjustable crushing roller. Both the adjustable crushing roller and the fixed crushing roller have serrated protrusions on their surfaces. The adjustable crushing roller is connected to the sliding motor through the connecting chamber via a rotating shaft.

[0012] As a further description of the above technical solution: Below the adjustable crushing roller is a conveyor belt. There are two sets of conveyor belts, with one end of the conveyor belt inclined downwards.

The lower end of the guide channel is provided with a auger conveyor device, and the lower end of the guide channel is connected to the feed inlet of the auger conveyor device.

[0014] Compared with the prior art, the beneficial effects of this utility model are: By setting up a pre-extrusion component, two parallel extrusion rollers are driven to rotate via a drive motor, rollers, and belt. This flattens and degassing PE fabric scraps, effectively reducing material volume and preventing "air gaps" or "jamming" during crushing. This improves subsequent crushing efficiency, reduces energy consumption, and makes the material more regular in shape, reducing blockages at the inlet of the guide chamber and crushing chamber, ensuring continuous and stable operation of the equipment.

[0015] By setting up an adjustment component, the telescopic rod can be driven to move within the telescopic sleeve through a threaded connection between the threaded rod and the connecting chamber. This allows for flexible changes in the distance between the adjustable crushing roller and the fixed crushing roller, thereby achieving adjustments for different crushing particle sizes to meet diverse needs. During adjustment, the sliding motor slides synchronously with the roller to ensure stable power transmission. Furthermore, the threaded rod drive has self-locking properties to ensure consistent crushing particle size. The buffer spring on the telescopic rod provides elastic cushioning, protecting the roller and drive structure, extending equipment life, and improving equipment versatility and adaptability.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-5 As shown, this utility model provides a technical solution: a PE fabric scrap recycling and crushing device, including a guide chamber 1, a pre-extrusion assembly 2 fixedly connected to the upper end of the guide chamber 1, the pre-extrusion assembly 2 including an extrusion chamber 201 fixedly connected to the upper end of the guide chamber 1, an extrusion roller 202 rotatably connected to the inner side of the extrusion chamber 201, a crushing chamber 3 welded to the lower end of the guide chamber 1, a groove 4 opened on the front surface of the crushing chamber 3, a fixing plate 5 provided below the groove 4, a slide rail 6 installed on the surface of the fixing plate 5, a sliding motor 7 slidably connected to the surface of the slide rail 6, an adjustment assembly 8 connected to one end of the sliding motor 7 by a flat key, the adjustment assembly 8 including a connecting chamber 801 connected to one end of the sliding motor 7 by a flat key, and a telescopic sleeve 802 fixedly connected to the right side of the connecting chamber 801.

[0021] Furthermore, a support plate 9 is provided at the bottom of the crushing chamber 3, and a guide channel 10 is provided on the inner side of the support plate 9. A auger conveyor device 11 is provided at the lower end of the guide channel 10, and the lower end of the guide channel 10 is connected to the feed inlet of the auger conveyor device 11. After the scrap material is crushed, it is processed by the conveyor belt 808 and the scraper 809 and falls into the guide channel 10 on the inner side of the support plate 9. It enters the feed inlet of the auger conveyor device 11 along the guide channel 10, and finally the auger conveyor device 11 discharges the processed scrap material.

[0022] Furthermore, a telescopic rod 803 is provided on the inner side of the telescopic sleeve 802. A buffer spring 804 is sleeved on the surface of the telescopic rod 803, and the right end of the buffer spring 804 abuts against the left end of the telescopic sleeve 802. A threaded rod 805 is provided on the inner side of the telescopic rod 803. A hexagonal slot is provided on the right end of the threaded rod 805, and the threaded rod 805 passes through the telescopic rod 803 and the telescopic sleeve 802 and is threadedly connected to the connecting chamber 801. When it is necessary to adjust the extension length of the telescopic rod 803, a tool is inserted into the hexagonal slot on the right end of the threaded rod 805 to rotate the threaded rod 805. Since the threaded rod 805 is threadedly connected to the connecting chamber 801, it will drive the telescopic rod 803 to move inside the telescopic sleeve 802. The buffer spring 804 provides buffering during the extension and retraction process, thereby realizing the adjustable gap between the crushing roller 806 and the fixed crushing roller 807.

[0023] Furthermore, an adjustable crushing roller 806 is provided on the inner side of the crushing chamber 3, and a fixed crushing roller 807 is provided on the left side of the adjustable crushing roller 806. Both the adjustable crushing roller 806 and the fixed crushing roller 807 have serrated protrusions on their surfaces. The adjustable crushing roller 806 is connected to the sliding motor 7 through the connecting chamber 801 via a rotating shaft. When the sliding motor 7 operates, it drives the adjustable crushing roller 806 to rotate through the rotating shaft passing through the connecting chamber 801. When it is necessary to adjust the distance between the adjustable crushing roller 806 and the fixed crushing roller 807, the distance between the two is adjusted by rotating the threaded rod 805. At the same time, during the adjustment process, the sliding motor 7 slides on the slide rail 6. With the position of the adjustable crushing roller 806, the scrap material can be crushed into different sizes according to different requirements.

[0024] Furthermore, a conveyor belt 808 is provided below the adjustable crushing roller 806. There are two sets of conveyor belts 808, and one end of the conveyor belt 808 is inclined downward. A scraper 809 is provided below the inclined end of the conveyor belt 808. The scraper 809 is in close contact with the surface of the conveyor belt 808. The scrap material after crushing falls onto the surface of the conveyor belt 808 and enters the guide groove 10 under the conveying of the conveyor belt 808. The scrap material adsorbed on the surface of the conveyor belt 808 will be scraped off by the scraper 809 at the bottom.

[0025] Furthermore, the crushing chamber 3 is welded to the fixed plate 5, and the slide rail 6 is fixedly connected to the surface of the fixed plate 5 by bolts. The sliding motor 7 is slidably connected to the slide rail 6 through the sliding base. When it is necessary to adjust the distance between the adjustable crushing roller 806 and the fixed crushing roller 807, the sliding motor 7 will move with the movement of the adjustable crushing roller 806 and always maintain a stable connection with the adjustable crushing roller 806.

[0026] Furthermore, two extrusion rollers 202 are provided, and the two extrusion rollers 202 are arranged parallel to each other. A sleeve wheel 203 is fixedly connected to the left end of the extrusion roller 202. A belt 204 is sleeved on the surface of the sleeve wheel 203. A drive motor 205 is connected to the inner side of the sleeve wheel 203. The drive motor 205 drives the belt 204 to transmit power. When the drive motor 205 starts, it drives the sleeve wheel 203 connected to it to rotate. The belt 204 drives the other sleeve wheel 203 to rotate, thereby making the two extrusion rollers 202 rotate synchronously and in the same direction. After the PE fabric scraps enter the extrusion chamber 201, they are extruded by the two extrusion rollers 202.

[0027] Working principle: During use, PE fabric scraps are fed into the top of the extrusion chamber 201 of the pre-extrusion assembly 2. The drive motor 205 drives two parallel extrusion rollers 202 to rotate in the same direction via the belt 204, flattening and venting the scraps, reducing their volume and improving subsequent crushing efficiency. The flattened scraps fall from the extrusion chamber 201 into the guide chamber 1, and are guided by gravity to the crushing chamber 3. The scraps first fall into the engagement area between the adjustable crushing roller 806 and the fixed crushing roller 807 for crushing. When different crushing particle sizes are required, an external hexagonal tool is inserted into the hexagonal slot on the right end of the threaded rod 805, and the threaded rod 805 is rotated. The threaded pair between the threaded rod 805 and the connecting chamber 801 drives the telescopic rod 803 to extend and retract within the telescopic sleeve 802, changing the adjustable particle size. The lateral position of the crushing roller 806 is such that the sliding motor 7 slides synchronously on the slide rail 6 with the adjustment action, ensuring continuous power transmission. The sliding motor 7 drives the adjustable crushing roller 806 to rotate through the rotating shaft, forming differential or same-speed shearing with the fixed crushing roller 807. The serrated protrusions tear and shear the scrap into the required particle size. The crushed particles fall onto the surface of the two sets of inclined downward-moving conveyor belts 808 and are carried downward. The residual particles adhering to the conveyor belt 808 are forcibly scraped off by the closely attached scraper 809 to prevent backflow. All particles flow into the feed inlet of the auger conveyor device 11 through the guide groove 10 and are forcibly, continuously and in a closed manner discharged from the machine through the spiral blades, completing the entire recycling and crushing process. This completes the use of a PE fabric scrap recycling and crushing device.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
