[0025] The beneficial effects of the present invention are:

[0026] 1. By controlling the rotating column, several groups of partition plates, extrusion plates, and telescopic plates are driven to rotate through the extrusion groove. Since the arc radius of the extrusion groove gradually decreases from top to bottom, the corresponding partition plates, extrusion plates, and telescopic plates can gradually shrink into the rotating column, thereby reducing the space volume to heat and compress the plastic fragments. When the extrusion plate shrinks to the limit, the extrusion space can be connected with the inside of the rotating column, and the harmful gases generated during the heating process of the plastic products can be sucked out to avoid air pollution.

[0027] 2. In the initial state, the baffle is located near the top of the storage box. The compressed plastic blocks fall on the top of the baffle and the extension plate in turn. Several groups of pressure sensors arranged in a rectangular array inside the baffle can monitor the pressure distribution on the top of the baffle. When the pressure is too concentrated, the four groups of electric push rods can be controlled to drive the baffle to shake to avoid the accumulation of compressed plastic blocks. At the same time, the baffle can be controlled to gradually descend according to the discharge amount of the compressed plastic blocks to avoid the dispersion of the compressed plastic blocks due to excessive drop, thereby improving the storage effect of the recycling device.

[0028] 3. By controlling the two sets of rotating plates to rotate toward the corresponding set of rotating rollers, and then controlling the two sets of rotating rollers to rotate slowly, when several sets of crushing teeth pass through the corresponding slag removal slots, the two sets of V-shaped scrapers will move and fit on the blades on both sides of the crushing teeth under the action of the corresponding extrusion springs, cleaning the plastic product fragments remaining on the crushing teeth to avoid affecting the subsequent recycling work, thereby improving the working stability of the recycling device.

[0029] 4. By utilizing the crushing mechanism to crush the plastic products, and then utilizing several groups of circulating extrusion spaces on the subsequent continuous extrusion mechanism 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. At the same time, the rotating column, partition plate, extrusion plate and heating plate provided in the extrusion block are utilized to heat the surface of the plastic compression block to a corresponding degree, thereby avoiding the problem of sharp edges and corners that may easily cause personal injury when the plastic is broken during compression, thereby improving the compression effect of the recycling device.

[0047] When recycling plastic products, the plastic products are first placed in the collecting hopper. The plastic products are chopped into fragments of similar size by the crushing mechanism 4, and 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, thus completing the recycling of the plastic products.

[0048] For example, Figure 3 and Figure 4 As shown, the crushing mechanism 4 includes a shell 401; a feed slot 402 is provided at the top of the shell 401; a discharge pipe 403 is provided at the bottom of the shell 401; the bottom of the discharge pipe 403 is set to an arc surface; a crushing chamber 404 is provided in the shell 401; two groups of rotating rollers 405 are provided in the crushing chamber 404; a number of groups of crushing teeth 406 are distributed in a circular array with equal intervals on the outer wall of each group of rotating rollers 405; each group of crushing teeth 406 is triangular prism-shaped; the several 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 provided on the top inner wall of the crushing chamber 404.

[0049] For example, Figure 5 As shown, the slag removal component 407 includes a fixed plate 4071; a rotating plate 4072 is provided on a side wall of the fixed plate 4071 close to the rotating roller 405; the side wall of the rotating plate 4072 away from the fixed plate 4071 is movably fitted on the outer wall of a corresponding group of rotating rollers 405; a plurality of groups of slag removal grooves 4073 are evenly spaced on a side wall of the rotating plate 4072 away from the fixed plate 4071; each group of the slag removal grooves 4073 is provided with two groups of scrapers 4074; the bottom of each group of the scrapers 4074 is hinged to the inner wall of the corresponding side of the slag removal groove 4073; a plurality of groups of extrusion springs 4075 are provided on the top side wall of each group of the scrapers 4074; the other end of each group of the extrusion springs 4075 is connected to the inner wall of the corresponding side of the slag removal groove 4073.

[0050] Plastic products enter the crushing chamber 404 between the two sets of rotating rollers 405 through the feed slot 402. Several sets of crushing teeth 406, staggered on the outer walls of the two sets of rotating rollers 405, crush the plastic products. The plastic fragments are then continuously fed into the continuous extrusion mechanism 6 through the discharge pipe 403. When the recycling device is idle, the two sets of rotating plates 4072 can be controlled to rotate toward the corresponding set of rotating rollers 405, and then the two sets of rotating rollers 405 can be controlled to rotate slowly. When the several sets of crushing teeth 406 pass through the corresponding slag removal slots 4073, two sets of V-shaped scrapers 4074, under the action of corresponding extrusion springs 4075, move to fit against the blade surfaces of the crushing teeth 406 on both sides, cleaning the plastic product fragments remaining on the crushing teeth 406 to avoid affecting subsequent recycling work, thereby improving the operating stability of the recycling device.

[0051] For example, Figure 6 、 Figure 7 、 Figure 8 and Figure 9 As 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 an annular 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 provided 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 provided 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 provided 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 provided in the telescopic cavity 608; a number of groups of first return springs 610 are evenly spaced between each group of partition plates 602 and the mounting columns 609; a number of groups of second return springs 611 are evenly spaced between each group of extrusion plates 603 and the mounting columns 609; an air guide cavity 613 is provided 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 provided in the rotating column 601, partition plates 602, extrusion plates 603 and extrusion blocks 7.

[0052] 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 be blocked by the corresponding two groups of extrusion plates 603 and four groups of telescopic plates 604 respectively. 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, realizing the plastic cyclic extrusion polymerization while eliminating the sharp edges on the surface of the plastic block, and 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 absorb the harmful gases generated in the hot pressing process to avoid air pollution, thereby improving the working effect of the recycling device and improving the environmental protection performance.

[0053] For example, Figure 10 As shown, the unloading mechanism 9 includes a guide plate 901; a conveyor belt 902 is provided in the guide plate 901; a unloading pipe 903 is provided at the end of the guide plate 901 away from the continuous extrusion mechanism 6; a unloading channel 904 is provided in the unloading pipe 903; the end of the unloading channel 904 away from the guide plate 901 is connected to the storage mechanism 11.

[0054] After the continuous extrusion mechanism 6 rotates through the extrusion block 7, it will dump the plastic compressed block onto the guide plate 901, and then the conveyor belt 902 will send the plastic compressed block into the discharge pipe 903, and then slide into the storage mechanism 11 through the discharge channel 904.

[0055] For example, Figure 11 and Figure 12As shown, the storage mechanism 11 includes a storage box 1101; a handle 1102 is provided on one side wall of the storage box 1101; four groups of electric push rods 1103 are symmetrically provided at the bottom of the storage box 1101; a baffle 1104 is provided in the storage box 1101; a plurality of pressure sensors are distributed in a rectangular array in the baffle 1104; two groups of telescopic slots 1106 are symmetrically opened on both side walls of the baffle 1104; each group of the telescopic slots 1106 is penetrated by a group of extension plates 1105; each group of the extension plates 1105 Several groups of support springs 1107 are evenly spaced on a side wall close to the baffle 1104; the other end of each group of support springs 1107 is connected to the inner wall of the corresponding side of the telescopic slot 1106; the end of each group of extension plates 1105 away from the baffle 1104 is movably in contact with the inner wall of the corresponding side of the storage box 1101; the output end of each group of electric push rods 1103 extends to the storage box 1101, and is transmission-connected to a group of shock absorbers 1108; the top of each group of shock absorbers 1108 is ball-connected to the bottom of the baffle 1104.

[0056] 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, so as 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, so as to avoid the dispersion of the plastic compressed blocks due to excessive drop, thereby improving the storage effect of the recycling device.

[0057] 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. When the extrusion plate 603 shrinks to the limit, the extrusion space can be connected with the interior 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.

[0058] 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, so as 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, so as to avoid the dispersion of the plastic compressed blocks due to excessive drop, thereby improving the storage effect of the recycling device.

[0059] 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 move and fit on the two side blades of the crushing teeth 406 under the action of the corresponding extrusion springs 4075, and clean up the plastic product fragments remaining on the crushing teeth 406 to avoid affecting the subsequent recycling work, thereby improving the working stability of the recycling device.

[0060] By utilizing the crushing mechanism 4 to crush the plastic products, and then utilizing several groups of circulating extrusion spaces on the subsequent 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. At the same time, the rotating column 601, the partition plate 602, the extrusion plate 603 and the heating plate provided in the extrusion block 7 are utilized to heat the surface of the plastic compression block to a corresponding degree, thereby avoiding the problem of sharp edges and corners that may easily cause personal injury when the plastic is broken during compression, thereby improving the compression effect of the recycling device.

[0062] Control the crushing mechanism to crush plastic products;
