Plastic scrap crushing and recycling equipment focuses on waste treatment at the production end, transforming scraps into reusable basic raw materials through physical crushing technology, connecting plastic production and recycling processes, and improving resource utilization. This type of equipment needs to take into account crushing efficiency, material purity, and environmental protection requirements. It is the core equipment for promoting the transformation of "waste to recycled resources" in the plastic circular economy. Therefore, there is a particular need for plastic scrap crushing and recycling equipment.

[0003] Chinese Patent CN218314643U, published on January 7, 2023, discloses a plastic scrap recycling machine. By setting up a support component, a drive component, a compaction component, and a positioning component, the plastic scrap can be easily compacted in the loading bin after it is crushed by an electric crusher and falls into the loading bin. This allows each loading bin to hold more plastic scrap, thus improving the practicality of the plastic scrap recycling machine. However, this plastic scrap recycling machine lacks effective safety measures in the feeding process. During frequent feeding operations, the plastic scrap is prone to splashing due to uneven force when it comes into contact with the mixing blades, posing a potential safety hazard to the operator.

Detailed Implementation

[0020] 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.

[0021] Please see Figure 1-5 This utility model provides a technical solution: a plastic scrap crushing and recycling device, including a base plate 1, a caster wheel 2 fixedly connected to the lower surface of the base plate 1, a collection bin 3 fixedly connected to the upper surface of the base plate 1, a rectangular groove 4 opened on one side surface of the collection bin 3, a drawer 5 slidably connected to the inner wall surface of the rectangular groove 4, a handle 6 fixedly connected to one side surface of the drawer 5, a first motor 7 fixedly connected to one side surface of the collection bin 3, a drive gear 8 rotatably connected to one side surface of the first motor 7, a driven gear 9 meshing with one side surface of the drive gear 8, a rotating rod 10 fixedly connected to one side surface of the driven gear 9, a stirring blade 11 fixedly connected to the outer wall surface of the rotating rod 10, a card 12 fixedly connected to one side surface of the collection bin 3, and a conveying mechanism 13 provided on the upper surface of the collection bin 3;

[0022] The conveying mechanism 13 includes a feeding housing 1301, which is fixedly connected to one side surface of the collection bin 3. A splash guard 1302 is fixedly connected to the upper surface of the feeding housing 1301. A guide block 1303 is fixedly connected to one side surface of the feeding housing 1301. A main shaft 1304 is rotatably connected to one side surface of the feeding housing 1301. A second motor 1305 is rotatably connected to one side surface of the main shaft 1304. A conveyor belt is slidably connected to the outer wall surface of the main shaft 1304. The conveyor track 1306 has an auxiliary shaft 1307 slidably connected to its inner wall surface. Through the arrangement of the feed housing 1301, splash guard 1302, guide block 1303, main shaft 1304, second motor 1305, conveyor track 1306, and auxiliary shaft 1307, in operation, the second motor 1305 drives the main shaft 1304 to rotate, and the main shaft 1304 drives the auxiliary shaft 1307 to rotate synchronously via the conveyor track 1306, forming a stable material conveying channel. Operators place scrap materials on the conveyor track 1306, and the materials move along the feed housing 1301 towards the collection bin 3 under the drive of the track. At this time, the splash guard 1302 can effectively block the splashing of scrap materials during the conveying and falling process, and avoid the waste or safety hazards caused by the overflow of materials into the equipment; the guide blocks 1303 on both sides play a role in limiting and guiding the materials, ensuring that they fall accurately into the collection bin 3, improving the feeding efficiency, and better ensuring the safety of the staff during operation.

[0023] Furthermore, the inner wall dimension of the rectangular groove 4 matches the outer wall dimension of the drawer 5 at the end furthest from the handle 6. The drawer 5 and the base plate 1 are parallel. With the setting of the rectangular groove 4 and the drawer 5, when the plastic scraps are crushed, they will fall into the collection bin 3. At this time, the operator can pull the drawer 5 outward through the handle 6. Since the inner wall dimension of the rectangular groove 4 matches the outer wall dimension of the drawer 5 at the end furthest from the handle 6, the drawer 5 can slide out smoothly in the rectangular groove 4, so that the crushed material can be easily taken out from the collection bin 3. The design of the drawer 5 being parallel to the base plate 1 ensures that it remains horizontal during the extraction process, preventing the material from spilling.

[0024] Furthermore, the outer wall dimensions of the driving gear 8 and the driven gear 9 are the same, and two rotating rods 10 of the same size are provided and are distributed in parallel. Through the arrangement of the driving gear 8 and the driven gear 9, when the first motor 7 is started, it drives the driving gear 8 to rotate. Since the outer wall dimensions of the driving gear 8 and the driven gear 9 are the same, they can achieve constant speed ratio transmission when they mesh, that is, the driving gear 8 and the driven gear 9 rotate in opposite directions at the same speed. This causes the rotating rod 10 fixedly connected to one side of the driven gear 9 and the rotating rod 10 directly connected to the driving gear 8 to rotate in opposite directions at the same speed. The stirring blades 11 on the two parallel rotating rods 10 thus form a shearing motion rotating in opposite directions, which powerfully stirs and crushes the plastic scraps falling into the collection bin 3. The constant speed ratio transmission of the gears of the same size ensures that the rotation speeds of the two rotating rods 10 are consistent, making the shearing force between the stirring blades 11 uniform and stable, which can efficiently and uniformly crush plastic scraps and improve the crushing quality and efficiency.

[0025] Furthermore, multiple stirring blades 11 of the same size are arranged at equal intervals along the two rotating rods 10. Multiple cards 12 of the same size are symmetrically distributed along the vertical center line of the collection chamber 3. Through the arrangement of the stirring blades 11, during use, when the two rotating rods 10 rotate in opposite directions under gear transmission, the multiple stirring blades 11 of equal size and spacing form an alternating rotating cutting array. After plastic scraps enter the collection chamber 3, they are first quickly grabbed and torn by the rotating stirring blades 11. The relative motion between the blades generates shearing force, initially crushing large pieces of scrap. The multiple equally spaced blades expand the crushing area, increase the contact frequency with the scraps, significantly improve crushing efficiency, and shorten processing time.

[0026] Furthermore, two guide blocks 1303 of the same size are provided and are symmetrically distributed along the vertical center line of the feeding shell 1301. The cross-section of the guide block 1303 is a right trapezoidal design. With the setting of the guide block 1303, when the plastic scrap is driven by the conveyor belt 1306 to move along the feeding shell 1301, the two symmetrically distributed guide blocks 1303 use their right trapezoidal cross-section shape to limit and guide the scrap. The hypotenuse of the right trapezoid can guide the irregularly shaped scrap to gather towards the center of the feeding shell 1301, effectively reducing the phenomenon of material jamming and blockage, and ensuring the continuity and stability of the feeding process.

[0027] Furthermore, the main rotating shaft 1304 and the auxiliary rotating shaft 1307 have the same outer wall dimensions and are distributed in parallel. The conveyor belt 1306 is distributed in parallel with the mixing blade 11 and the rotating rod 10. Through the arrangement of the main rotating shaft 1304 and the auxiliary rotating shaft 1307, during use, the second motor 1305 drives the main rotating shaft 1304 to rotate. Since the main rotating shaft 1304 and the auxiliary rotating shaft 1307 have the same outer wall dimensions and are distributed in parallel, the two achieve stable transmission cooperation through the conveyor belt 1306. When the main rotating shaft 1304 rotates, it relies on the friction between the belt and the rotating shaft to drive the auxiliary rotating shaft 1307 to rotate synchronously, ensuring that the conveyor belt 1306 runs at a uniform speed and smoothly, accurately conveying the plastic scraps to the collection bin 3.

[0028] Furthermore, the splash guard 1302 is distributed parallel to the mixing blade 11 and the rotating rod 10. The horizontal center line of the splash guard 1302 intersects the vertical center line of the feed housing 1301 perpendicularly. With the splash guard 1302 in use, when plastic scraps are conveyed to the collection bin 3 by the conveyor belt 1306 and fall down, the splash guard 1302, which is distributed parallel to the mixing blade 11 and the rotating rod 10, can effectively block the splashes that may be generated after the material collides with the mixing blade 11, thus effectively ensuring the personal safety of the operators.

[0029] Working principle: First, the scrap material is placed on the conveyor belt 1306 of the conveyor mechanism 13. The second motor 1305 starts and drives the main shaft 1304 to rotate. The main shaft 1304 drives the auxiliary shaft 1307 to rotate through the transmission of the conveyor belt 1306, so that the conveyor belt 1306 runs smoothly and conveys the scrap material along the feed shell 1301 to the collection bin 3. The splash plate 1302 on the feed shell 1301 can prevent the scrap material from splashing during the conveying and falling process. The guide blocks 1303 on both sides play a limiting role to ensure stable conveying of the scrap material. After the scrap material falls into the collection bin 3, the first motor 7 starts to work and drives the drive gear 8 to rotate. The drive gear 8 meshes with the driven gear 9 and drives the two rotating rods 10 to rotate synchronously in opposite directions. The multiple stirring blades 11 on the rotating rods 10 rotate accordingly to stir and crush the scrap material that falls into the collection bin 3. During the crushing process, multiple cards 12 help to block and disperse the scraps, improving the crushing effect. The crushed plastic granules accumulate in the collection chamber 3. When cleaning is required, the drawer 5, which is slidably connected to the rectangular groove 4, can be pulled out by the handle 6 for convenient and quick collection and processing of the crushed material. The universal wheels 2 allow the equipment to move flexibly, making it easy to use in different working scenarios. This completes the process of using a plastic scrap crushing and recycling equipment.

[0030] 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.
