Description

Technical Field

[0001] The invention relates to the technical field of plastic crushing, in particular to a plastic product recycling crusher. Background Art

[0002] Plastic is an indispensable material in people's daily life. This material is basically within reach in life. While plastic brings convenience to people's lives, it also causes serious pollution to the social environment. Most plastics are discarded after one-time consumption. So far, the academic community believes that plastic products may not be decomposed for tens to hundreds of years in the natural environment due to their stable physical and chemical structures. In order to protect the environment, people have begun to recycle discarded plastics, which can not only reduce environmental pollution, but also save some costs. The plastics can be crushed and reprocessed by a crusher so that the recycled plastics can be reused.

[0003] When existing crushers crush plastic products, they are put into the crusher feed port, and then crushed by crushing rollers. However, when crushing plastic products, especially plastic bottles, some bottle caps are sealed at the bottle mouth when they are put into the crusher feed port, so that the gas in the bottle cannot be discharged. It is necessary to manually open the bottle cap, flatten the plastic bottle, release the gas in the bottle, and then put the plastic bottle into the crushing box, which increases the operation steps; if the sealed plastic bottle is directly put into the crushing box, during the crushing process by the crushing roller, due to the gas in the plastic bottle, the plastic bottle is relatively round and easy to roll on the crushing roller, making it difficult for the crushing roller to crush the rolling plastic bottle, resulting in incomplete crushing of the plastic bottle, and the rolling plastic bottle is easy to splash out from the feed port, requiring secondary feeding. When a plastic bottle is crushed, there may be liquid in the plastic bottle. Due to the seal of the bottle cap, the liquid cannot be discharged, and the bottle cap needs to be unscrewed manually to pour out the liquid in the bottle. If it is crushed directly, the liquid will flow to the crushing roller after crushing, making the small pieces of plastic bottle plastic after crushing easily stick to the crushing roller. As time goes by, more and more plastic pieces will accumulate on the crushing roller. The plastic pieces stuck to the crushing roller will slow down the crushing speed and reduce the crushing efficiency. Summary of the invention

[0004] In view of the problem in the prior art that plastic products, especially plastic bottles, are easy to roll on the crushing roller during the crushing process, making them difficult to crush, and the plastic bottles may contain liquid, which flows onto the crushing roller after being crushed, making it easy for the crushed plastic to adhere to the crushing roller, thereby reducing the crushing efficiency, a plastic product recycling crusher is proposed.

[0017] Beneficial effects of the present invention:

[0018] 1. The puncturing component is used to puncture and flatten the plastic bottle. The liquid in the punctured plastic bottle is sucked out by the drying component. The liquid absorbed by the drying component is squeezed out by the twisting component, so that the drying component can be used continuously. The puncturing roller rotates in the crushing box to drive the cone block to rotate. Under the action of the cone block, the plastic bottle is punctured. Under the action of the puncturing roller, the punctured plastic bottle is flattened so that the flattened plastic bottle just falls between the two crushing rollers, which is convenient for crushing. The volume of the plastic bottle is reduced, which is convenient for crushing, and the crushing efficiency is improved. The plastic bottle is crushed more evenly and the recycling efficiency is improved.

[0019] 2. The liquid is introduced into the shell through the connecting plate, and the U-shaped frame slides in the shell, driving the sponge rollers to slide, so that the two relative sponge rollers are in contact or separated. When the two sponge rollers are in contact, the liquid entering the shell is absorbed. When the two sponge rollers are separated, the flattened plastic bottle can fall from between the two sponge rollers, and the liquid on the plastic bottle is absorbed at the same time. The liquid dripping from the sponge roller is introduced into the bottom of the inner side of the shell through the drainage plate, and the liquid is guided out of the shell to the outside of the crushing box through the water pipe, so that the liquid in the plastic bottle will not stick to the crushing roller, causing small pieces of plastic to stick to the crushing roller, affecting the uniformity of the quality of the crushed plastic by the crushing roller.

[0020] 3. The U-shaped frame moves back and forth in the shell, thereby driving the sponge roller to move back and forth, and then driving the second spur gear to move back and forth, so that the second spur gear rolls on the second rack. Under the action of the second rack, the second spur gear rotates, driving the rotating shaft to rotate, driving one of the circular plates to rotate, and the other circular plate is fixedly connected to the slider through a fixed shaft, so that one end of the sponge roller is twisted, and the liquid absorbed by the sponge roller is screwed out. When the U-shaped frame moves toward the center of the shell, the sponge roller absorbs the liquid entering the shell. When the U-shaped frame moves away from the center of the shell, the sponge roller twists and screws out the absorbed liquid, so that the sponge roller can be used continuously, and the sponge roller is easier to absorb the liquid on the plastic bottle.

[0044] Specifically, the plastic bottle is punctured by the puncturing roller 41, and the liquid in the punctured plastic bottle will flow out and fall on the connecting plate 62, and the liquid is introduced into the outer shell 61 through the connecting plate 62. The U-shaped frame 65 slides in the outer shell 61, driving the sponge roller 64 to slide, so that the two relative sponge rollers 64 contact or separate. When the two sponge rollers 64 contact, the liquid entering the outer shell 61 is absorbed. When the two sponge rollers 64 separate, the flattened plastic bottle can fall from between the two sponge rollers 64 and absorb the liquid on the plastic bottle at the same time. Through the drainage plate 66, the liquid dripping from the sponge roller 64 is introduced into the inner bottom of the outer shell 61, and through the water pipe 63, the liquid is guided out of the outer shell 61 to the outside of the crushing box 11, so that the liquid in the plastic bottle will not stick to the crushing roller 21, causing small pieces of plastic to stick to the crushing roller 21, affecting the uniformity of the quality of the crushed plastic by the crushing roller 21.

[0045] Reference Figure 8 and Fig. 9 The reciprocating assembly 7 includes a reciprocating block 71 fixedly connected to a plurality of U-shaped frames 65, a first rack 74 fixedly connected to opposite ends of the plurality of reciprocating blocks 71, an incomplete gear 75 rotatably connected between two opposite first racks 74, the incomplete gear 75 meshingly connected with the first rack 74, a reciprocating rod 73 fixedly connected to one end of the reciprocating block 71 away from the U-shaped frame 65, a first spring 72 sleeved on the reciprocating rod 73, and the first spring 72 is fixedly connected to the outer wall of the housing 61 at one end close to the reciprocating block 71.

[0046] Specifically, the incomplete gear 75 rotates, thereby driving the two first racks 74 between the incomplete gears 75 to move, thereby driving the first rack 74 on the upper side of the incomplete gear 75 to move toward the sponge roller 64, driving the first rack 74 on the lower side of the incomplete gear 75 to move away from the sponge roller 64, driving the two reciprocating blocks 71 to move in opposite directions, driving the two reciprocating rods 73 to move in opposite directions, thereby compressing the first spring 72 on the upper side of the incomplete gear 75, and stretching the first spring 72 on the lower side of the incomplete gear 75. When the teeth of the incomplete gear 75 leave the first rack 74, the first rack 74 on the lower side of the incomplete gear 75 is engaged. 4, the first spring 72 is reset, driving the reciprocating rod 73 to reset, driving the reciprocating block 71 to reset, and then the incomplete gear 75, when continuously rotating, drives the reciprocating block 71 to reciprocate under the cooperation of the first rack 74 and the first spring 72, drives the U-shaped frame 65 to reciprocate, drives the sponge roller 64 to reciprocate, so that the two relative sponge rollers 64 open and close, thereby not only absorbing the liquid on the flattened plastic bottle, but also making the flattened plastic bottle slowly fall from between the two sponge rollers 64 and be crushed by the crushing roller 21, realizing the flattening and puncturing of the plastic bottle and absorbing the liquid therein.

[0047] Reference Figure 3 and Figure 6-Figure 8The second transmission assembly 8 includes a second transmission shaft 84 fixedly connected to the end of the two piercing rollers 41 away from the piercing shaft 42, a first transmission shaft 82 fixedly connected to the two incomplete gears 75, the two first transmission shafts 82 are both rotatably connected to the outer shell 61, and a third transmission wheel 81 fixedly mounted on the two first transmission shafts 82 and the two second transmission shafts 84. The two opposite third transmission wheels 81 are connected through a third belt 83.

[0048] Specifically, by rotating the piercing roller 41, the second transmission shaft 84 is driven to rotate, and the third transmission wheel 81 on the second transmission shaft 84 is driven to rotate. Under the action of the third belt 83, the third transmission wheel 81 on the first transmission shaft 82 is driven to rotate, and the first transmission shaft 82 is driven to rotate, thereby driving the incomplete gear 75 to rotate continuously, thereby achieving the reciprocating movement effect of the reciprocating component 7.

[0049] Reference Fig.10 and Fig.11 The torsion assembly 9 includes a circular plate 93 fixedly connected to both ends of the sponge roller 64, two symmetrically distributed slide grooves 96 opened on the U-shaped frame 65, a slider 95 slidably connected to the inner side of the two slide grooves 96, one of the circular plates 93 is rotatably connected to the slider 95 on the corresponding side through a rotating shaft, and the other circular plate 93 is fixedly connected to the slider 95 on the corresponding side through a fixed shaft, a second spring 94 fixedly connected between the slider 95 and the inner wall of the slide groove 96, a second spur gear 91 fixedly sleeved on the shaft wall of the rotating shaft, and a second rack 92 fixedly connected to the housing 61 at a position corresponding to the second spur gear 91, and the second spur gear 91 is meshedly connected with the second rack 92.

[0050] Specifically, the U-shaped frame 65 reciprocates in the shell 61, thereby driving the sponge roller 64 to reciprocate, and then driving the second spur gear 91 to reciprocate, so that the second spur gear 91 rolls on the second rack 92. Under the action of the second rack 92, the second spur gear 91 rotates, driving the rotating shaft to rotate, driving one of the circular plates 93 to rotate, and the other circular plate 93 is fixedly connected to the slider 95 through the fixed shaft, so that one end of the sponge roller 64 is twisted, and the liquid absorbed by the sponge roller 64 is screwed out. When the U-shaped frame 65 moves toward the center of the shell 61, the sponge roller 64 absorbs the liquid entering the shell 61. When the U-shaped frame 65 moves away from the center of the shell 61, the sponge roller 64 is twisted. The absorbed liquid is twisted out, so that the sponge roller 64 can be used continuously. When the two sponge rollers 64 are in contact, the flattened plastic bottle will continue to move downward, thereby squeezing the two sponge rollers 64 to both sides. At this time, the sponge roller 64 continuously absorbs the liquid on the plastic bottle. The sponge roller 64 is squeezed, so that the slider 95 slides inside the slide groove 96, driving the sponge roller 64 to move inside the U-shaped frame 65, squeezing the second spring 94. At this time, the second spur gear 91 still rolls on the second rack 92, driving the second spur gear 91 to rotate, thereby causing one end of the sponge roller 64 to twist, and then quickly wringing out the sponge roller 64 that absorbs the liquid, so that the sponge roller 64 can more easily absorb the liquid on the plastic bottle. The rest of the structure is the same as that of Example 2.

[0051] Based on the embodiments 1-3, the working principle of the present invention is as follows: when in use, the plastic bottle is put into the crushing box 11 through the feeding bin 13, and the two puncturing rollers 41 rotate to drive the conical block 43 to rotate, so as to puncture the plastic bottle. Under the action of the puncturing rollers 41, the punctured plastic bottle is flattened. After the plastic bottle containing liquid is punctured, the liquid will flow out and fall on the connecting plate 62, enter the shell 61 through the connecting plate 62, and rotate through the incomplete gear 75, thereby driving the first rack 74 at the top and bottom of the incomplete gear 75 to move in opposite directions. Under the action of the first spring 72, the first rack 74 will reciprocate, drive the reciprocating block 71 to reciprocate, drive the U-shaped frame 65 to reciprocate, and drive the sponge roller 64 to reciprocate, so that the two opposite sponge rollers 64 are in contact or separated. When the two sponge rollers 64 are in contact, the shell 61 The liquid in the plastic bottle is absorbed, and when the two sponge rollers 64 are separated, the flattened plastic bottle can fall between the two sponge rollers 64, and the second spur gear 91 rolls on the second rack 92, thereby driving the second spur gear 91 to rotate, thereby causing one end of the sponge roller 64 to twist, and the liquid absorbed by the sponge roller 64 is screwed off, so that the sponge roller 64 can continue to absorb the liquid on the plastic bottle, and the flattened plastic bottle is continuously moved downward, and the two sponge rollers 64 are squeezed to both sides, which also causes the second spur gear 91 to rotate, causing the sponge roller 64 to twist, and the absorbed liquid is screwed out. The plastic bottle that falls on the crushing roller 21 is in a flattened state and is just stuck between the two crushing rollers 21, which is convenient for crushing. At the same time, the liquid in the plastic bottle is absorbed, and no liquid will flow out of the crushed plastic bottle to affect the crushing.

[0052] It should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention.
