Description

Technical Field

[0001] This utility model relates to the field of sorting device technology, and in particular to a high-throughput intelligent sorting device for recycling waste plastics. Background Technology

[0002] Waste plastic sorting equipment is an automated device that integrates the transportation and sorting of waste plastics. It is based on a conveying channel and a sorting mechanism as its core architecture. It achieves material processing through the series cooperation of the feeding bin, conveying mechanism and sorting mechanism, and is widely used in common plastic recycling and sorting scenarios.

[0003] Traditional sorting equipment uses a single-channel conveyor mode with a constant conveying speed, requiring frequent stops for replenishment and making continuous feeding impossible. Furthermore, the mainstream conveyor mechanisms are mainly integral roller conveyors or single-speed belts, with fixed conveying speeds that can lead to material jamming. Simultaneously, the reduced conveying speed of already sorted plastics lowers the sorting and processing rate. To address these issues, under current technological conditions, some technologies have attempted to optimize feeding using double-layer silos and electric gates, shortening the replenishment interval, and increasing conveying speed by increasing the roller conveyor's tilt angle and boosting conveying power. However, in actual use, the double-layer silo volume remains insufficient, the continuous feeding time is only slightly extended, and the roller conveyor and belt speeds remain unchanged, failing to improve the congestion problem in the transition area.

Detailed Implementation

[0030] 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.

[0031] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model is provided: a high-throughput intelligent sorting device for recycling waste plastics, including a support frame 1, a conveying mechanism 2 installed on the top of the support frame 1, the function of the conveying mechanism 2 is to transport waste plastics to the sorting position, and a squeezing mechanism 3 is provided on the bottom right side of the conveying mechanism 2, the function of the squeezing mechanism 3 is to squeeze the sorted plastics into blocks for easy subsequent processing.

[0032] The conveying mechanism 2 includes a feeding barrel 201, which is fixedly connected to the top left side of the support frame 1. Multiple partitions 202 are fixedly connected at equal intervals on the inner wall of the feeding barrel 201. Multiple diversion components 203 are fixedly connected to the right side of the outer wall of the partitions 202. Multiple conveying components 204 are provided at the bottom right side of the feeding barrel 201.

[0033] Multiple diversion components 203 each include a connecting plate 2031, which is fixedly connected to the bottom right side of the partition 202, and multiple guide vanes 2032 are fixedly connected at equal intervals to the top wall of the connecting plate 2031.

[0034] Each of the multiple conveying components 204 includes multiple motors 2041, model Y2-100L1-4. The stator three-phase current generates a rotating magnetic field, which induces current in the rotor. The rotor is driven to rotate by electromagnetic force. Multiple motors 2041 are equidistantly installed on the front side of the middle of the support frame 1. The output ends of multiple motors 2041 are fixedly connected to rollers 2043. The outer walls of multiple rollers 2043 are driven to connect to conveyor belts 2042. Multiple rollers 2043 are equidistantly rotatably connected to the inner side of the support frame 1.

[0035] The bottom of each of the multiple motors 2041 is fixedly connected to a motor bracket 5, and the multiple motor brackets 5 are fixedly connected to the front side of the outer wall of the support frame 1.

[0036] Specifically, the bottom of the support frame 1 is fixedly connected to the ground to form the support frame for the entire equipment. Waste plastic to be sorted is poured into the feed hopper 201 in batches from the top opening. Three partitions 202 are evenly distributed along the height of the feed hopper 201, dividing the internal space of the feed hopper 201 into three independent channels. The bottom of each channel corresponds to a conveyor belt, guiding the waste in the feed hopper 201 to the upper, middle, and lower conveyor belts on the equipment. One end of the connecting plate 2031 is fixedly connected to the bottom outlet edge of the feed hopper 201, and the other end extends to the inlet of the conveyor belt of the conveyor assembly 204, connecting the feed hopper 201 and the conveyor assembly 204. The gaps are blocked to prevent waste from falling during the transfer process. Several inclined guide vanes 2032 are evenly distributed on the upper surface of the connecting plate 2031. The guide vanes 2032 can change the falling direction of the waste, thus preventing the plastic from falling during the process. The waste materials are evenly distributed on the surface of the conveyor belt 2042 to avoid local accumulation. There are three conveying components 204, which correspond to the upper, middle and lower layers of the conveyor belt. Each conveying component 204 contains three rollers. The part near the feed hopper 201 is the conveying roller, which is responsible for conveying the waste materials from the inlet of the conveyor belt to the sorting area. The middle part is the sorting roller, where the plastic waste materials are sorted by the sorting device. The last one, near the recycling bin 301, is the unloading roller, which is responsible for conveying the sorted waste materials to the recycling bin 301. The three rollers rotate at different speeds. The conveying roller and the unloading roller are faster, which prevents the waste materials from being stuck during the conveying process and increases the overall conveying capacity. The sorting roller is slower, which provides sufficient time for the sorting device to identify and separate different plastics. The three rollers are connected to the output shafts of three motors 2041 with different speeds via drive belts.

[0037] Reference Figure 2 , Figure 4 and Figure 5The extrusion mechanism 3 includes a recycling box 301, which is located at the bottom right side of the support frame 1. The left and right inner walls of the recycling box 301 are slidably connected to an extrusion plate 302. The left side of the outer wall of the extrusion plate 302 is fixedly connected to two hydraulic push rods 306, which are of model DYTZ. The gear pump outputs pressure oil, which is sent to the oil cylinder through the valve group to realize the reciprocating linear motion of the piston rod. The rear side of the top wall of the recycling box 301 is fixedly connected to a fixing plate 303, and the top wall of the fixing plate 303 is slidably connected to a moving component 304.

[0038] The movable component 304 includes a movable plate 3041, which is mounted on the top of the fixed plate 303. A rack 3042 is provided at the bottom of the movable plate 3041 and is fixedly connected to the middle of the top wall of the fixed plate 303. Two sliding tenons 3043 are fixedly connected to the left side of the bottom wall of the movable plate 3041. Rollers 3044 are rotatably connected to the four corners of the bottom of the movable plate 3041. A drive component 305 is installed on the right side of the top wall of the movable plate 3041.

[0039] The drive assembly 305 includes a gear carrier 3053, with a drive gear 3052 rotatably connected to the left side inside the gear carrier 3053 and a driven gear 3054 rotatably connected to the right side inside the gear carrier 3053. The rear middle part of the rack 3042 is fixedly connected to the output end of the motor 3051. Its model is RS-380. The energized coil rotates in the magnetic field and continuously commutates to maintain rotation.

[0040] Specifically, after sorting, different types of waste are diverted through the internal diversion channel of the equipment and fall into the corresponding recycling bins 301. Each recycling bin 301 collects one type of waste plastic. A liquid level sensor is installed on the inner wall of the recycling bin 301. The output shaft of the motor 3051 is fixed to the drive gear 3052 via a key connection, driving the drive gear 3052 to rotate. The drive gear 3052 meshes with the driven gear 3054, thus driving the driven gear 3054 to start rotating. The teeth of the driven gear 3054 mesh with the teeth of the rack 3042 fixed at the bottom of the recycling bin 301, causing the rack 3042 to rotate. As the driven gear 3054 rotates, the moving plate 3041, which is fixedly connected to the axle of the driven gear 3054, begins to slide on the inner wall of the recycling bin 301. The two sides of the moving plate 3041 are embedded in the recycling bin. In the sliding tenon 3043 on the inner wall of the box 301, the sliding tenon 3043 limits the sliding path of the moving plate 3041. Several rollers 3044 are installed at the bottom of the moving plate 3041. The rollers 3044 contact the bottom of the recycling box 301 to reduce the friction during movement. When the moving plate 3041 slides to the preset position and moves into place, the hydraulic push rod 306 installed on the outer wall of the other side of the recycling box 301 is activated. The telescopic end of the hydraulic push rod 306 passes through the side wall of the recycling box 301 and is fixedly connected to the extrusion plate 302, pushing the extrusion plate 302 to move towards the moving plate 3041. The extrusion plate 302 and the moving plate 3041 are located on opposite sides of the recycling box 301 and together form a closed extrusion space, which extrudes the plastic waste in the extrusion space into a fixed and uniform shape, reducing the space occupied by the waste and facilitating centralized temporary storage and subsequent transfer and processing.

[0041] Reference Figure 1 and Figure 2 Two unloading troughs 4 are installed on the right side of the support frame 1, and both unloading troughs 4 are located on the top of the recycling box 301;

[0042] Specifically, the unloading chute 4 slopes downwards, and its width gradually narrows from the conveyor belt 2042 toward the recycling bin 301.

[0043] Working principle: The support frame 1 serves as the support framework for the entire equipment. Waste plastic to be sorted is poured into the feed hopper 201 through the top opening. The partition 202 divides the internal space of the feed hopper 201 into three parts, guiding the waste in the feed hopper 201 to the upper, middle, and lower conveyor belts respectively. The connecting plate 2031 connects the feed hopper 201 and the conveying assembly 204 to prevent waste from falling. Guide plates 2032 are evenly distributed on it, ensuring that the plastic is evenly distributed on the surface of the conveyor belt 2042 during the falling process. The conveying assembly 204... There are three rollers in total: the one closest to the feed hopper 201 is the conveying roller, the middle one is the sorting roller where plastic waste is sorted, and the last one is the unloading roller. The three rollers have different speeds. The conveying roller and the unloading roller are faster to prevent stagnation and increase the conveying capacity, while the sorting roller is slower to give the sorting work sufficient time. The three rollers are driven by motors 2041 with different speeds. This set of mechanisms can increase the conveying throughput in three-dimensional space and solve the problems of short continuous feeding time and stagnation of waste plastic in the transition area in the existing technology.

[0044] After being sorted, the waste falls into the corresponding recycling bin 301. When the internal space of the recycling bin 301 is full, the motor 3051 is started first, which drives the drive gear 3052 and the driven gear 3054 to start rotating. The driven gear 3054 meshes and rotates on the rack 3042. As the driven gear 3054 rotates, the moving plate 3041 begins to slide on the recycling bin 301. The sliding tenon 3043 defines the route, and the roller 3044 reduces friction. After moving into place, the hydraulic push rod 306 is activated to push the extrusion plate 302 to move. The extrusion plate 302 and the moving plate 3041 together form an extrusion space, which extrudes the plastic waste into a fixed and uniform shape, making it convenient for centralized temporary storage and subsequent processing.

[0045] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
