Description

Technical Field

[0001] This invention relates to the field of plastic scrap recycling technology, and in particular to a scrap recycling machine for plastic product processing. Background Technology

[0002] Plastic products are various products made from synthetic resin plastics as the main raw material, with the addition of fillers, plasticizers, stabilizers, color masterbatches and other additives, and then processed through molding. A large amount of plastic product scraps are also generated during the production process. Plastic product processing scraps are fixed thermoplastic wastes with high recycling value in the production process, and are high-quality raw materials for the plastic circular economy. Therefore, scraps are generally recycled and reused. To this end, patent CN209851384U discloses a high-efficiency crushing and recycling machine for processing plastic products. Its structure includes a crushing machine body, an extrusion device, and a separation device. By setting the extrusion device at the top of the crushing machine body, gas is introduced into the cylinder through the air guide pipe, causing the output end of the cylinder to extend downward and push the extrusion plate and the metal base plate downward, thereby squeezing the plastic in the crushing machine body downward, so that the plastic quickly contacts the top of the first crushing roller and the second crushing roller for rapid crushing. This achieves the beneficial effect of enabling lighter plastics to quickly contact the crushing shaft and improving crushing efficiency. By setting the separation device inside the crushing machine body, when larger plastics enter the top of the separation inclined screen, the separation inclined screen blocks the larger plastics and guides the plastics to the discharge port, and then into the second collection box for collection. This achieves the beneficial effect of quickly screening and collecting plastics that do not meet the standards, improving the screening efficiency of plastics that do not meet the standards. The existing technical solutions described above have the following drawbacks: The technology uses two sets of crushing rollers for crushing, which leads to wear on the rollers during long-term operation. This wear causes the crushing gap to gradually increase, which cannot be automatically compensated for, requiring manual adjustment and making the operation cumbersome and affecting production efficiency. Furthermore, the increased gap makes it difficult to maintain a stable particle size, resulting in increasingly larger and finer output particles. The lack of automatic obstacle avoidance means that the presence of metal or hard foreign objects can easily cause roller deformation, equipment jamming, and other malfunctions, severely impacting the overall lifespan of the machine. Therefore, a new waste recycling machine for plastic product processing is needed to solve these problems. Summary of the Invention

[0003] The purpose of this invention is to provide a scrap recycling machine for plastic product processing, which solves the problems of existing crushing structures where rollers are prone to wear during long-term operation, resulting in a gradually increasing crushing gap that cannot be automatically compensated for and requires manual adjustment. This is cumbersome, affects production efficiency, and makes it difficult to maintain stable particle size after the gap widens, leading to larger and larger output particles. Furthermore, the lack of automatic avoidance function makes it easy for rollers to deform and jam when metal or hard foreign objects are mixed in with the material, seriously affecting the service life of the entire machine.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a scrap recycling machine for plastic product processing, comprising a recycling bin and a first crushing roller; A second crushing roller is provided on one side of the inside of the recycling bin, and a first crushing roller is provided on one side of the second crushing roller. A guide plate is installed at the bottom of the recycling bin, and support frames are installed on both sides of the bottom of the recycling bin. An installation plate is fixed at one end of the support frame, and an automatic compensation structure is provided at both ends of the first crushing roller. The automatic compensation structure includes a moving trough located inside the front and rear ends of the recycling bin. A moving seat is installed inside the moving trough, and a connecting shaft is installed inside the moving seat. One end of the connecting shaft is fixed to one end of the first crushing roller, and a mounting frame is installed at the other end of the connecting shaft.

A threaded sleeve is installed at the bottom end of the limit bearing, and a lead screw is installed inside the threaded sleeve. A constant force coil spring is installed at one end of the lead screw.

[0005] Preferably, a mounting block is installed on the outer side of the constant force coil spring, a limiting block is installed on the outer side of the transmission rod, and a limiting groove is formed on the inner side of the transmission shaft, with the limiting block and the limiting groove forming a limiting structure.

[0006] Preferably, a reducer is installed at one end of the transmission rod, a servo motor is installed at one end of the reducer, and the other end of the transmission rod is inserted into the interior of the transmission shaft, forming a transverse reciprocating movement structure between the transmission rod and the transmission shaft.

[0007] Preferably, one side of the limiting bearing is fixed to one end of the mounting bracket, the top end of the threaded sleeve is fixed to the bottom end of the limiting bearing, the inner side of the threaded sleeve is provided with an internal thread, the outer side of the lead screw is provided with an external thread, and the threaded sleeve and the lead screw form a threaded connection.

[0008] Preferably, the bottom end of the guide plate is provided with a separation structure, the separation structure including a collection box, the collection box is installed at the bottom end of the guide plate, a spiral conveying shaft is installed inside the collection box, a stainless steel roller is installed at the top end of the collection box, a strong magnet is installed inside the stainless steel roller, a connecting rod is installed at one end of the strong magnet, and one end of the connecting rod is fixed to one end of the mounting plate.

[0009] Preferably, a drive motor is installed at one end of the collection box, a synchronous pulley is installed at the rear end of the stainless steel roller, the outer side of the output shaft of the drive motor is connected to the synchronous pulley via a belt, and a guide sleeve is installed at the other end of the stainless steel roller, the guide sleeve being inserted into a limiting ring groove on one side of the mounting plate.

[0010] Preferably, guide plates are installed on both sides of the stainless steel roller, and the two ends of the guide plates are fixed to one side of the support frame. The guide plates are symmetrically distributed on both sides of the stainless steel roller.

[0011] Preferably, a fixing plate is installed on one side of the top of the collection box, a fixing rod is installed at the middle position of the fixing plate, a scraper is installed on the outside of the fixing rod, and torsion springs are installed at both ends of the scraper.

[0012] Preferably, one end of the torsion spring is fixed to one end of the scraper, and the other end of the torsion spring is fixed to one end of the fixed plate. Two sets of torsion springs are provided, and the two sets of torsion springs are symmetrically distributed on the outer sides of both ends of the fixed rod.

[0013] Preferably, the fixing rod extends through the interior of the bottom end of the scraper, and the fixing rod and the scraper form a movable connection.

[0014] The present invention provides a waste recycling machine for plastic product processing, which has the following advantages: With an automatic compensation structure, when the first and second crushing rollers wear out during long-term operation, the constant force coil spring is slightly unfolded and in a pre-tightened state. During normal crushing operation, when the rollers wear out, the gap between the two rollers will increase. At this time, the constant force coil spring, which is in a pre-tightened state, releases its own contraction force and continuously pulls the screw to rotate. The screw drives the screw sleeve to rotate. Under the guidance of the guide structure on one side, the screw sleeve drives the first crushing roller to move to one side, accurately compensating for the gap caused by the wear of the first and second crushing rollers. This achieves automatic wear compensation, ensuring that the crushing gap is always maintained at the preset value, thereby ensuring that the crushed particle size is consistent over a long period of time. This effectively avoids problems such as increasingly larger and finer output particles, soft material slippage, and inability to cut due to increased gap. Furthermore, when metal or hard foreign objects are mixed into the scrap, the impact force of the foreign objects on the first crushing roller is greater than the preload of the constant force coil spring. The constant force coil spring will be compressed, causing the first crushing roller to automatically move to one side to avoid the foreign objects and prevent the roller teeth and roller body from being damaged or deformed due to hard contact. After the foreign objects are discharged, the constant force coil spring automatically resets, driving the first crushing roller back to the preset gap, ensuring that the crushing operation continues. The constant force coil spring has the characteristics of constant output tension and basically unchanged tension within the effective stroke. The entire working process does not require manual adjustment of the gap, and there is no need to stop the machine to deal with wear and foreign object problems. This greatly increases the continuous working time of the equipment, reduces the wear of equipment parts, extends the service life of the whole machine, reduces maintenance costs, and ensures the long-term stable and efficient operation of the equipment. Furthermore, the use of limit blocks and limit grooves can ensure that rotation can continue during movement, achieving the effect of both transmitting torque and axial extension and sliding. By setting up a separation structure and by placing a strong magnet inside the stainless steel drum in a semi-circular arrangement, a strong adsorption force is formed on the top surface of the stainless steel drum, which adsorbs iron filings, screws and other iron impurities in the plastic particles onto the surface of the stainless steel drum. When the top area of ​​the stainless steel drum rotates to the bottom position, the adsorption force disappears, and the iron filings and screws fall off into the collection box under their own weight. Furthermore, the torsion spring provides torque to the scraper, causing it to elastically adhere to the bottom surface of the stainless steel roller, scraping off any iron filings and screws that have not been removed in time, thus completing the separation of plastic particles and iron impurities.

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.

[0018] Please see Figures 1-13 The present invention provides a scrap recycling machine for plastic product processing, comprising a recycling bin 1 and a first crushing roller 2; A second crushing roller 8 is provided on one side of the inside of the recycling bin 1, and a first crushing roller 2 is provided on one side of the second crushing roller 8. A guide plate 7 is installed at the bottom of the recycling bin 1, and support frames 4 are installed on both sides of the bottom of the recycling bin 1. An installation plate 5 is fixed at one end of the support frame 4, and an automatic compensation structure 3 is provided at both ends of the first crushing roller 2.

[0019] Reference Figures 1-9As shown, the automatic compensation structure 3 includes a moving groove 306, which is located inside the front and rear ends of the recycling box 1. A moving seat 307 is installed inside the moving groove 306, and a connecting shaft 3011 is installed inside the moving seat 307. One end of the connecting shaft 3011 is fixed to one end of the first crushing roller 2, and a mounting frame 301 is installed at the other end of the connecting shaft 3011. A limit bearing 3012 is installed at the rear end of the mounting frame 301, and a bevel gear set 308 is installed at the front end of the mounting frame 301. A drive shaft 302 is installed on one side of the bevel gear set 308, and a drive rod 303 is installed inside the drive shaft 302. A threaded sleeve 3013 is installed at the bottom end of the limit bearing 3012, and a lead screw 3014 is installed inside the threaded sleeve 3013. A constant force coil spring 3016 is installed at one end of the lead screw 3014. A mounting block 3015 is installed on the outer side of the constant force coil spring 3016, a limiting block 309 is installed on the outer side of the transmission rod 303, and a limiting groove 3010 is opened on the inner side of the transmission shaft 302. The limiting block 309 and the limiting groove 3010 form a limiting structure. A reducer 304 is installed at one end of the transmission rod 303, a servo motor 305 is installed at one end of the reducer 304, and the other end of the transmission rod 303 is inserted into the interior of the transmission shaft 302. The transmission rod 303 and the transmission shaft 302 form a transverse reciprocating movement structure. One side of the limit bearing 3012 is fixed to one end of the mounting bracket 301, the top end of the threaded sleeve 3013 is fixed to the bottom end of the limit bearing 3012, the inner side of the threaded sleeve 3013 is provided with an internal thread, the outer side of the lead screw 3014 is provided with an external thread, and the threaded sleeve 3013 and the lead screw 3014 form a threaded connection.

[0020] When recycling scrap plastic products, the scrap is poured into the recycling bin 1. Simultaneously, the motor is started to rotate the second crushing roller 8, and the servo motor 305 is started to rotate the first crushing roller 2. When the second crushing roller 8 and the first crushing roller 2 rotate simultaneously, the scrap is bitten and clamped by the roller teeth, and subjected to the combined effects of compression, shearing, and tearing, causing the scrap to be torn, cut, and crushed into small particles or fragments that meet the requirements, thus completing the crushing process. When the first crushing roller 2 and the second crushing roller 8 experience wear during prolonged operation, the lead screw 3014 drives the lead sleeve 3013 to move. During this movement, the lead sleeve 3013 moves the mounting bracket 301, which in turn moves the second crushing roller 8, adjusting the wear gap between the second crushing roller 8 and the first crushing roller 2 to ensure the crushed particle size meets the preset requirements. Meanwhile, the constant force coil spring 3016 acts as an automatic gap compensation and foreign object avoidance actuator. One end of the constant force coil spring 3016 is fixed to the mounting block 3015, and the other end is connected to the outer side of one end of the lead screw 3014. It always provides a stable and uniform preload to the lead screw 3014. At this time, the constant force coil spring 3016 is slightly unfolded and is in a preloaded state. During normal crushing operation, when the rollers wear, the gap between the two rollers will increase. At this time, the constant force coil spring 3016, which is in a preloaded state, releases its own contraction force and continues to pull the lead screw 3014 to rotate. The lead screw 3014 drives the sleeve 3013 to rotate. At this time, the sleeve 3013 drives the first crushing roller 2 to move to one side under the guidance of the guide structure on one side. It accurately compensates for the gap caused by the wear of the first crushing roller 2 and the second crushing roller 8, realizes the automatic wear compensation work, and ensures that the crushing gap is always maintained at the preset value. This ensures that the crushing particle size is consistent in the long term and effectively avoids problems such as the output particle size becoming larger and larger, soft materials slipping, and inability to cut due to the increase in gap. When metal or hard foreign objects are mixed into the scrap material, the impact force of the foreign objects on the first crushing roller 2 is greater than the preload of the constant force coil spring 3016. The constant force coil spring 3016 will be compressed, causing the first crushing roller 2 to automatically retract to one side to avoid the foreign objects and prevent the roller teeth and roller body from being damaged or deformed due to hard contact. After the foreign objects are discharged, the constant force coil spring 3016 automatically resets, driving the first crushing roller 2 back to the preset gap, ensuring that the crushing operation continues. The constant force coil spring 3016 has the characteristics of constant output tension and basically unchanged tension within the effective stroke. The entire working process does not require manual adjustment of the gap, and there is no need to stop the machine to deal with wear and foreign object problems. It greatly increases the continuous working time of the equipment, reduces the wear of equipment parts, extends the service life of the whole machine, reduces maintenance costs, and ensures the long-term stable and efficient operation of the equipment.

[0021] Reference Figures 10-13As shown, a separation structure 6 is provided at the bottom of the guide plate 7. The separation structure 6 includes a collection box 601, which is installed at the bottom of the guide plate 7. A screw conveyor shaft 6013 is installed inside the collection box 601. A stainless steel roller 605 is installed at the top of the collection box 601. A strong magnet 608 is installed inside the stainless steel roller 605. A connecting rod 606 is installed at one end of the strong magnet 608. One end of the connecting rod 606 is fixed to one end of the mounting plate 5. A drive motor 604 is installed at one end of the collection box 601, and a synchronous pulley 603 is installed at the rear end of the stainless steel roller 605. The outer side of the output shaft of the drive motor 604 is connected to the synchronous pulley 603 via a belt. A guide sleeve 607 is installed at the other end of the stainless steel roller 605. The guide sleeve 607 is inserted into the limiting ring groove on one side of the mounting plate 5. Guide plates 602 are installed on both sides of the stainless steel roller 605. The two ends of the guide plates 602 are fixed to one side of the support frame 4. The guide plates 602 are symmetrically distributed on both sides of the stainless steel roller 605. A fixing plate 6012 is installed on one side of the top of the collection box 601. A fixing rod 6011 is installed in the middle of the fixing plate 6012. A scraper 609 is installed on the outside of the fixing rod 6011. Torsion springs 6010 are installed at both ends of the scraper 609. One end of the torsion spring 6010 is fixed to one end of the scraper 609, and the other end of the torsion spring 6010 is fixed to one end of the fixing plate 6012. Two sets of torsion springs 6010 are provided, and the two sets of torsion springs 6010 are symmetrically distributed on the outer sides of both ends of the fixing rod 6011.

[0022] The crushed plastic granules are guided by the guide plate 7 and fall onto the surface of the stainless steel drum 605. When the material falls, the drive motor 604 is started, which drives the screw conveyor shaft 6013 to rotate and feed the material. At the same time, the stainless steel drum 605 is driven to rotate slowly. After the plastic granules fall onto the surface of the stainless steel drum 605, the strong magnet 608 inside the stainless steel drum 605 is arranged in a semi-circular shape, which creates a strong adsorption force on the top surface of the stainless steel drum 605. Iron filings, screws and other iron impurities in the plastic granules are adsorbed onto the surface of the stainless steel drum 605. When the top area of ​​the stainless steel drum 605 rotates to the bottom position, the adsorption force disappears, and the iron filings and screws fall into the collection box 601 under their own weight and are conveyed out by the screw conveyor shaft 6013. The plastic granules that fall onto the surface of the stainless steel drum 605 slide onto the guide plates 602 on both sides and are conveyed away. The top of the guide plate 602 maintains a certain gap with the surface of the stainless steel drum 605, so as not to scrape off the adsorbed iron filings and screws. When the stainless steel roller 605, which has adsorbed iron filings and screws, rotates to the position of the scraper 609, the torsion spring 6010 provides torque to the scraper 609, causing it to elastically adhere to the bottom surface of the stainless steel roller 605, scraping off the iron filings and screws that have not been removed in time, thus completing the separation of plastic particles and iron impurities. After the separation is completed, the crushed plastic particles can be recycled again, thereby completing the recycling of waste materials from plastic product processing.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
