[0025] When recycling plastic products, the plastic products are first placed in a collecting hopper, and the plastic products are chopped into fragments of similar size by a crushing mechanism 4. Then, the plastic fragments continuously enter the continuous extrusion mechanism 6 for continuous extrusion polymerization. Subsequently, the plastic blocks enter the storage mechanism 11 through the unloading mechanism 9 for storage, thereby completing the recycling of the plastic products.

[0026] For example, Figure 3 and Figure 4 As shown, the crushing mechanism 4 includes a shell 401; a feed slot 402 is opened on the top of the shell 401; a discharge pipe 403 is arranged at the bottom of the shell 401; the bottom of the discharge pipe 403 is set as an arc surface; a crushing chamber 404 is arranged in the shell 401; two groups of rotating rollers 405 are arranged in the crushing chamber 404; a number of groups of crushing teeth 406 are evenly spaced and distributed in a circular array on the outer wall of each group of rotating rollers 405; each group of crushing teeth 406 is in the shape of a triangular prism; the groups of crushing teeth 406 on the outer walls of the two groups of rotating rollers 405 are staggered; two groups of slag removal components 407 are symmetrically arranged on the top inner wall of the crushing chamber 404.

[0028] The plastic products enter between the two groups of rotating rollers 405 in the crushing chamber 404 through the feed slot 402, and the multiple groups of crushing teeth 406 staggeredly arranged on the outer walls of the two groups of rotating rollers 405 crush the plastic products, and then the plastic fragments are continuously input into the continuous extrusion mechanism 6 through the discharge pipe 403. When the recycling device is idle, the two groups of rotating plates 4072 can be controlled to rotate toward the corresponding group of rotating rollers 405, and then the two groups of rotating rollers 405 can be controlled to rotate slowly. When the multiple groups of crushing teeth 406 pass through the corresponding slag removal slots 4073, the two groups of V-shaped scrapers 4074 will be movably attached to the blade surfaces of the crushing teeth 406 on both sides under the action of the corresponding extrusion springs 4075, and the plastic product fragments remaining on the crushing teeth 406 are cleaned to avoid affecting the subsequent recycling work, thereby improving the working stability of the recycling device.

[0029] For example, Figure 6 , Figure 7 , Figure 8 and Fig. 9As shown, the continuous extrusion mechanism 6 includes a rotating column 601; a plurality of groups of partition plates 602 are movably penetrated on the outer wall of the rotating column 601 in a circular array; a side wall of each group of partition plates 602 away from the rotating column 601 is movably fitted to the bottom of the discharge pipe 403; two groups of extrusion plates 603 are arranged between two adjacent groups of partition plates 602; a group of telescopic plates 604 are movably penetrated on the two side walls of each group of extrusion plates 603 close to the two adjacent groups of partition plates 602; each group of extrusion plates 603 and telescopic plates 604 are movably penetrated on the outer wall of the rotating column 601; the cross-section of each group of extrusion plates 603 and telescopic plates 604 is fan-shaped; a group of limit blocks 605 are arranged between two adjacent groups of telescopic plates 604; a plurality of groups of exhaust holes 606 are provided on the side wall of the rotating column 601 close to the air purifier 8; the extrusion plates Two groups of sealed air cavities 607 are symmetrically opened in 603; each group of telescopic plates 604 can move through the corresponding group of sealed air cavities 607; a telescopic cavity 608 is arranged in the rotating column 601; each group of partition plates 602, extrusion plates 603 and telescopic plates 604 can move through the telescopic cavity 608; a mounting column 609 is arranged in the telescopic cavity 608; a number of groups of first reset springs 610 are evenly spaced between each group of partition plates 602 and the mounting columns 609; a number of groups of second reset springs 611 are evenly spaced between each group of extrusion plates 603 and the mounting columns 609; an air guide cavity 613 is arranged in each group of extrusion plates 603; a number of air guide holes 612 are evenly distributed on the inner wall of one side of each group of air guide cavities 613; a heating plate is arranged in the rotating column 601, the partition plates 602, the extrusion plates 603 and the extrusion block 7.

[0030] By controlling the rotation of the rotating column 601, the plastic product fragments can continuously enter between the two adjacent groups of partition plates 602, and are blocked by the corresponding two groups of extrusion plates 603 and four groups of telescopic plates 604 respectively, and then the corresponding partition plates 602, extrusion plates 603, and telescopic plates 604 pass through the extrusion groove 12. Since the arc radius of the extrusion groove 12 gradually decreases from top to bottom, the corresponding partition plates 602, extrusion plates 603, and telescopic plates 604 can shrink into the rotating column 601, thereby reducing the space volume to heat and extrude the plastic fragments, and eliminating the sharp edges and corners on the surface of the plastic block while realizing the plastic cyclic extrusion polymerization. When the extrusion plate 603 shrinks to the limit, several groups of air guide holes 612 can connect the extrusion space with the telescopic cavity 608 through the air guide cavity 613, and the harmful gases generated in the hot pressing process are sucked out to avoid air pollution, thereby improving the working effect of the recycling device and the environmental protection performance.

[0034] In the initial state, the baffle 1104 is located near the top of the storage box 1101, and the plastic compressed blocks fall on the top of the baffle 1104 and the extension plate 1105 in turn. Several groups of pressure sensors distributed in a rectangular array in the baffle 1104 can monitor the pressure distribution on the top of the baffle 1104. When the pressure is too concentrated, the four groups of electric push rods 1103 can be controlled to drive the baffle 1104 to shake to avoid the accumulation of plastic compressed blocks. At the same time, the baffle 1104 can be controlled to gradually descend according to the discharge amount of the plastic compressed blocks to avoid the dispersion of the plastic compressed blocks caused by excessive drop, thereby improving the storage effect of the recycling device.

[0035] By controlling the rotating column 601 to drive several groups of partition plates 602, extrusion plates 603, and telescopic plates 604 to rotate through the extrusion groove 12, since the arc radius of the extrusion groove 12 gradually decreases from top to bottom, the corresponding partition plates 602, extrusion plates 603, and telescopic plates 604 can gradually shrink into the rotating column 601, thereby reducing the space volume to heat and compress the plastic fragments, and when the extrusion plate 603 shrinks to the limit, the extrusion space can be connected with the inside of the rotating column 601, and the harmful gases generated during the heating process of the plastic products can be sucked out to avoid air pollution, thereby improving the recycling efficiency of plastic products and improving environmental protection performance.

Several groups of pressure sensors distributed in a rectangular array in the baffle 1104 can monitor the pressure distribution on the top of the baffle 1104. When the pressure is too concentrated, the four groups of electric push rods 1103 can be controlled to drive the baffle 1104 to shake to avoid the accumulation of plastic compressed blocks. At the same time, the baffle 1104 can be controlled to gradually descend according to the discharge amount of the plastic compressed blocks to avoid the dispersion of the plastic compressed blocks caused by excessive drop, thereby improving the storage effect of the recycling device.

[0037] By controlling the two groups of rotating plates 4072 to rotate toward the corresponding group of rotating rollers 405 respectively, and then controlling the two groups of rotating rollers 405 to rotate slowly, when several groups of crushing teeth 406 pass through the corresponding slag removal grooves 4073, the two groups of V-shaped scrapers will be movable and fitted on the two side blades of the crushing teeth 406 under the action of the corresponding extrusion springs 4075, and the plastic product fragments remaining on the crushing teeth 406 are cleaned to avoid affecting the subsequent recycling work, thereby improving the working stability of the recycling device.

[0038] By utilizing the crushing mechanism 4 to crush the plastic products, and then utilizing a plurality of groups of circulating extrusion spaces on the post-continuous extrusion mechanism 6 to extrude and aggregate the plastic fragments, the problem of loose compression caused by direct compression of the plastic products by the existing recycling device can be avoided.
