Description

Technical Field

[0001] This utility model relates to the field of plastic waste recycling technology, and in particular to a plastic waste recycling device equipped with a crushing structure. Background Technology

[0002] Plastic waste recycling equipment is used to process and recycle waste plastics. It can crush the collected and sorted waste plastics through a crushing device, remove impurities and pollutants after washing, and then re-granulate them through melting.

[0003] In existing plastic waste recycling devices, the crushing mechanism is installed inside the recycling device. Once the crushing mechanism jams or is damaged, it is inconvenient to repair.

[0004] A publicly available technical solution, CN218519005U, discloses a waste recycling device for plastic product manufacturing, relating to the field of plastic crushing technology. Specifically, it includes a base with support legs vertically connected to each of the four corners of the base's bottom. A crushing shell is fixedly connected to the top of the base, and a discharge port is opened on one side of the bottom outer wall of the crushing shell. The two sides of the crushing shell are concave inwards in an arc shape, forming a structure that is narrow in the middle and wide at both ends, with crushing openings at the concave arcs. A crushing shaft mounting shell is connected to the outside of the crushing openings, and the cross-section of the crushing shaft mounting shell is semi-circular. A crushing shaft is inserted through the crushing shaft mounting shell, and both ends of the crushing shaft are mounted on the side surfaces of the crushing shaft mounting shell via bearings. Several sets of blade holders are equidistantly connected along the outer wall of the crushing shaft. This facilitates user maintenance of the strip-shaped crushing blades and blade holders, extending the service life of the device.

[0005] In actual implementation, the two ends of the crushing shaft mounting housing are mounted on the crushing housing by screws on two sets of connecting plates. When it is necessary to disassemble the crushing shaft mounting housing, all the screws need to be removed, which is quite troublesome. Summary of the Invention

[0026] 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.

[0027] This utility model provides a technical solution:

[0028] Please see Figures 1 to 4 A plastic waste recycling device with a crushing structure includes a processing device body 1, a feed inlet at the top of the processing device body 1, a discharge outlet at the bottom of the processing device body 1, crushing shell mechanisms 2 on both the left and right sides of the processing device body 1, and an adjustment mechanism 3 on the crushing shell mechanism 2.

[0029] The crushing shell mechanism 2 includes an arc-shaped shell 201 that is detachably connected to the main body 1 of the processing device;

[0030] The adjustment mechanism 3 includes a guide slider 303 fixed on the arc-shaped outer shell 201, and a bidirectional lead screw 304 is connected inside the guide slider 303 through a lead screw sleeve. A transmission worm gear 305 is fixedly installed in the middle of the bidirectional lead screw 304, and a transmission worm 306 is meshed and connected above the transmission worm gear 305. A guide plate 302 is slidably installed on the outside of the guide slider 303, and support frames 301 are fixedly installed on both the upper and lower sides of the guide plate 302. The support frames 301 are fixedly installed on the main body 1 of the processing device.

[0031] By adopting the above technical solution, after rotating the transmission worm 306, the transmission worm 306 can drive the transmission worm wheel 305 to rotate through the meshing force. When the transmission worm wheel 305 rotates, it can drive the bidirectional lead screw 304 to rotate. When the bidirectional lead screw 304 rotates, under the action of the lead screw sleeve, it can drive the guide slider 303 to slide inside the guide plate 302, thereby moving the arc-shaped outer shell 201 away from the processing device body 1 and exposing the crushing mechanism installed inside the arc-shaped outer shell 201. This facilitates the maintenance of the crushing mechanism and greatly improves the efficiency of disassembling the arc-shaped outer shell 201. When it is necessary to install the arc-shaped outer shell 201, the transmission worm 306 can be rotated in the opposite direction, and the arc-shaped outer shell 201 can be pressed tightly against the processing device body 1. A sealing strip is provided at the connection between the processing device body 1 and the arc-shaped outer shell 201 to seal the arc-shaped outer shell 201 and the processing device body 1, preventing the crushed plastic from being exposed through the gap between the arc-shaped outer shell 201 and the processing device body 1.

[0032] Specifically, such as Figure 2 and Figure 4 As shown, a drive shaft 4 is installed inside the main body 1 of the processing device, and a crushing shaft 5 is installed between the two sets of drive shafts 4. Crushing blades 6 are fixedly installed on the outside of the crushing shaft 5. Two sets of connecting plates 7 are provided between the drive shaft 4 and the crushing shaft 5. One set of connecting plates 7 is fixed on the drive shaft 4, and the other set of connecting plates 7 is fixed at both ends of the crushing shaft 5. The two sets of connecting plates 7 are connected by screws.

[0033] The crushing shell mechanism 2 also includes connecting ear plates 202 fixed on the upper and lower sides of the arc-shaped shell 201. The connecting ear plates 202 are provided with mounting grooves at the connection between them and the main body 1 of the processing device. The connecting ear plates 202 have guide holes 203 inside, and guide rods 204 pass through the guide holes 203. The guide rods 204 are fixed on the main body 1 of the processing device.

[0034] By adopting the above technical solution, the arc-shaped outer shell 201 covers the outside of the crushing blade 6. The power output end of the motor is fixed on the transmission shaft 4. When the transmission shaft 4 rotates, it can drive the crushing shaft 5 to rotate, thereby crushing the waste plastic inside the main body 1 of the processing device. When the crushing blade 6 needs to be repaired, the screws between the connecting plates 7 can be rotated to separate the two sets of connecting plates 7 from each other, thereby separating the crushing shaft 5 from the transmission shaft 4, making it convenient to disassemble the crushing blade 6. When the arc-shaped outer shell 201 moves, it can slide on the guide rod 204 through the guide hole 203. The guide rod 204 can guide the arc-shaped outer shell 201.

[0035] Working principle: When waste plastic needs to be crushed, it is fed into the feed port at the top of the main body 1 of the processing device. The power output of the motor is fixed on the transmission shaft 4. When the transmission shaft 4 rotates, it drives the crushing shaft 5 to rotate. The crushing blades 6 crush the waste plastic, and the crushed waste plastic is discharged from the discharge port at the bottom. When maintenance of the crushing mechanism is required, the transmission worm 306 is rotated. The transmission worm 306 drives the transmission worm wheel 305 to rotate through the meshing force. When the transmission worm wheel 305 rotates, it drives the double-acting screw 304 to rotate. 4. During rotation, the guide slider 303 can slide inside the guide plate 302 under the action of the lead screw sleeve. When the arc-shaped outer shell 201 moves, it can slide on the guide rod 204 through the guide hole 203. The guide rod 204 can guide the arc-shaped outer shell 201, thereby moving the arc-shaped outer shell 201 away from the processing device body 1 and exposing the crushing mechanism installed inside the arc-shaped outer shell 201. The screws between the connecting plates 7 can be rotated to separate the two sets of connecting plates 7 from each other, thereby separating the crushing shaft 5 from the transmission shaft 4 and facilitating the disassembly of the crushing blade 6.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
