Description

Technical Field

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

[0002] In short, plastic recycling refers to the process of converting discarded plastic products into usable resources or raw materials through a series of processing procedures. This process aims to reduce the pollution of plastic waste to the environment, while realizing the recycling of resources and promoting sustainable development. Plastic recycling mainly includes the following key steps: collection, sorting, cleaning, crushing, melting and reprocessing. First, discarded plastic products are collected and then carefully sorted to ensure that different types of plastics can be properly handled. Next, these plastics will be thoroughly cleaned to remove stains and impurities attached to the surface. After that, they will be broken into small pieces for subsequent melting processing. During the melting process, the plastic is heated to a molten state to form reprocessable plastic raw materials. Finally, these raw materials can be used to produce new plastic products or other products.

[0003] In the recycling process of plastic bottles, given the huge number of plastic bottles, the current crushing step is often to crush the bottle caps and the bottle bodies together. Since the bottle bodies and bottle caps have different properties, the crushed bottle caps need to be separated from the mixture in the subsequent steps. However, because the bottle bodies and bottle caps have been crushed and mixed, the subsequent separation operation is difficult, which is not only time-consuming and labor-intensive, but also has poor separation effect. For this reason, we propose a plastic product recycling device. Summary of the invention

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Example 1: Please refer to Figure 1-10 The present invention provides a technical solution: a feeding bin 1 and a crushing bin 2, further comprising a rotating plate 82, the rotating plate 82 being located in the feeding bin 1, and a plurality of arc grooves 83 being equidistantly opened on the side of the rotating plate 82; a clamping plate 3, the clamping plate 3 being installed in the feeding bin 1, and the clamping plate 3 being located on both sides of the arc groove 83 on the rotating plate 82;

[0033] A bidirectional driving unit 7, wherein the bidirectional driving unit 7 is arranged in the feeding bin 1, and the clamping plate 3 is connected to the bidirectional driving unit 7, and the bidirectional driving unit 7 is used to drive the clamping plates 3 located on both sides of the arc groove 83 to clamp the plastic bottle, and simultaneously drive the clamping plates 3 at both ends of the plastic bottle to rotate in opposite directions respectively, so as to separate the bottle body and the bottle cap;

[0034] The advantage of the bidirectional drive unit 7 is that it can automatically separate the plastic bottle caps and the bottle bodies when the plastic bottles are crushed and recycled. The automatic separation can significantly improve the efficiency of the plastic bottle crushing and reduce the reliance on manual operation, thereby speeding up the recycling speed and improving the overall recycling efficiency. At the same time, the automatic separation reduces the need for manual sorting of bottle caps and bottle bodies, reduces labor costs, and improves economic benefits. Moreover, plastic bottles are usually made of different plastic materials, such as PET for the bottle body and PP for the bottle cap. These materials have different physical and chemical properties. Mixed recycling will reduce the quality of recycled plastics. By separating the bottle body and the bottle cap, different types of plastics can be ensured to be more effectively recycled and processed, thereby improving the purity of the recycled plastics and providing higher quality raw materials for subsequent reuse. Moreover, separating the bottle caps and the bottle body can make the subsequent crushing and sorting work more efficient. The separated plastic bottle bodies and bottle caps can be processed through the crusher more quickly and are easier to carry out subsequent screening and sorting work.

[0035] The crushing unit 4 is arranged in the crushing bin 2, and the crushing unit 4 is used to crush the plastic bottle body and the plastic bottle cap respectively.

[0036] The advantage of setting up the crushing unit 4 is that the bottle cap and the bottle body can be crushed separately. Since the bottle cap and the bottle body are different in material, thickness, hardness, etc., separate crushing can select the most suitable crushing method and parameters according to their characteristics, thereby improving the crushing efficiency. Moreover, separate crushing can avoid excessive wear and increased energy consumption caused by mixed crushing. Optimizing the crushing according to the different characteristics of the bottle cap and the bottle body helps to reduce energy consumption and improve energy utilization efficiency.

[0039] The advantage of the separation and crushing setting is that the separated plastic bottle body and bottle cap can be crushed separately, which helps to utilize resources more efficiently. The crushed plastic particles can be further classified according to their type and quality so that they can be used to produce different types of plastic products.

[0041] When the bottle body and the bottle cap enter the first crushing chamber 51 and the second crushing chamber 52 respectively, the staff drives the driving motor 64 to work, and the driving motor 64 drives the rotating shaft 53 to rotate. The rotation of the rotating shaft 53 drives the driving gear 62 arranged thereon to rotate.

[0043] The clamping member 8 includes a conveying shaft 81 rotatably arranged in the feeding bin 1, and the conveying shaft 81 is connected to a rotating plate 82. A plurality of connecting plates 84 are arranged at the positions of the arc grooves 83 on both sides of the rotating plate 82. The connecting plates 84 are L-shaped. A fixed tube 85 is rotatably arranged on the connecting plate 84. A sliding rod 86 is slidably arranged in the fixed tube 85. The sliding rod 86 is connected to the clamping plate 3. A limiting plate 87 is arranged on the fixed tube 85. An extrusion spring 88 is sleeved on the sliding rod 86 between the limiting plate 87 and the clamping plate 3.

Positioning rods 2 910 are arranged on both sides of the feed bin 1, and arc plates 1 911 and arc plates 2 912 are respectively arranged on the positioning rods 2 910 on both sides, and teeth grooves 913 are opened on the arc plates 1 911 and the arc plates 2 912, and a rotating gear 914 engaged with the teeth grooves 913 is arranged on the fixed tube 85.

[0045] The advantage of the rotating member 9 is that the bottle body and the bottle cap can be automatically separated, and the design of the fixing needle 93 can ensure the stability during separation.

[0046] The screening element 10 includes a guide plate 101 arranged on the feed bin 1, a guide chute 102 is provided on the guide plate 101, one end of the guide chute 102 is connected to the opening of the first crushing chamber 51, a plurality of filter holes 103 are provided on the guide chute 102, a filter bin 104 is provided at the bottom of the guide plate 101, the filter bin 104 is connected to the filter holes 103, the bottom surface of the filter bin 104 is inclined, a through slot 105 is provided on the filter bin 104, and the through slot 105 is connected to the opening of the second crushing chamber 52.

[0047] The power member 11 includes a power shaft 111 rotatably arranged on the power bin 61, the power shaft 111 is connected to the rotating shaft 2 54, a power shaft 112 is rotatably arranged on the feeding bin 1, the power shaft 112 is connected to the conveying shaft 81, and power pulleys 113 are arranged on both the power shaft 111 and the power shaft 112, and a power belt 114 is arranged on the power pulley 113.

[0048] When the plastic bottles need to be crushed and recycled, the plastic bottles are first put into the feeding bin 1, and the power shaft 111 rotates under the drive of the rotating shaft 2 54, and the power shaft 111 rotates through the power pulley 113 and the power belt 114 to drive the power shaft 2 112 to rotate, and the power shaft 2 112 rotates to drive the conveying shaft 81 to rotate, and the conveying shaft 81 rotates to drive the clamping plate 3 to rotate, so that the clamping plate 3 rotates in the feeding bin 1, and the clamping plate 3 is squeezed with the plastic bottles when rotating, because the design of the squeezing spring 88 makes the plastic The bottle is clamped and fixed between the clamping plates 3 located on both sides of the rotating plate 82. At this time, the clamping plates 3 continue to drive the plastic bottle to rotate. When the magnetic block 96 located in the fixed tube 85 moves into the magnetic field range of the magnetic plate 2 99, the magnetic plate 2 99 and the magnetic block 96 repel each other, causing the magnetic block 96 to move in the fixed tube 85, driving the extension rod 95 and the positioning block 92 to move synchronously, thereby pushing the fixing pin 93 located on the positioning block 92 to extend from the through hole 94 and come into contact with the plastic bottle, thereby improving the fixing effect of the plastic bottle.

[0049] During the continuous rotation of the splint 3, the rotating gears 914 on the fixed tubes 85 on both sides of the rotating plate 82 respectively engage with the tooth grooves 913 on the arc plate 1 911 and the arc plate 2 912. At the same time, because the tooth grooves 913 on the arc plate 1 911 and the arc plate 2 912 are opened at different positions, the rotating gears 914 on the fixed tubes 85 on both sides of the rotating plate 82 will rotate in different directions, thereby driving the sliding rod 86 and the splint 3 to rotate in different directions, so that the bottle cap and the bottle body of the plastic bottle are subjected to rotational forces in different directions, thereby separating the bottle cap from the bottle body.

[0050] At this time, the clamping plate 3 causes the magnetic block 96 to separate from the magnetic field range of the magnetic plate 2 99 and enter the magnetic field range of the magnetic plate 1 98 during the continuous movement. Since the magnetic plate 1 98 and the magnetic block 96 attract each other, the magnetic block 96 drives the fixing pin 93 to separate from the plastic bottle body and the bottle cap under the action of magnetic force. The clamping plate 3 contacts the guide plate 101 during the continuous movement. Under the push of the guide plate 101, the plastic bottle body and the bottle cap fall into the guide chute 102 and move in the guide chute 102 under the action of their own gravity. At this time, the bottle body falls into the first crushing chamber 51 through the guide chute 102, and the bottle cap falls into the filter bin 104 through the filter hole 103 during the movement. The bottom surface of the filter bin 104 is inclined, so that the bottle cap falling into the filter bin 104 falls into the second crushing chamber 52 through the through groove 105.

[0051] When in use, when it is necessary to crush and recycle plastic bottles, the plastic bottles are first put into the feeding bin 1, and the power shaft 111 rotates under the drive of the rotating shaft 2 54, and the power shaft 111 rotates through the power pulley 113 and the power belt 114 to drive the power shaft 2 112 to rotate, and the power shaft 2 112 rotates to drive the conveying shaft 81 to rotate, and the conveying shaft 81 rotates to drive the clamping plate 3 to rotate, so that the clamping plate 3 rotates in the feeding bin 1, and the clamping plate 3 is squeezed with the plastic bottles when rotating, because the design of the squeezing spring 88 makes The plastic bottle is clamped and fixed between the clamping plates 3 located on both sides of the rotating plate 82. At this time, the clamping plates 3 continue to drive the plastic bottle to rotate. When the magnetic block 96 located in the fixed tube 85 moves into the magnetic field range of the magnetic plate 2 99, the magnetic plate 2 99 and the magnetic block 96 repel each other, causing the magnetic block 96 to move in the fixed tube 85, driving the extension rod 95 and the positioning block 92 to move synchronously, thereby pushing the fixing pin 93 located on the positioning block 92 to extend from the through hole 94 and come into contact with the plastic bottle, thereby improving the fixing effect of the plastic bottle.

[0052] During the continuous rotation of the splint 3, the rotating gears 914 on the fixed tubes 85 on both sides of the rotating plate 82 respectively engage with the tooth grooves 913 on the arc plate 1 911 and the arc plate 2 912. At the same time, because the tooth grooves 913 on the arc plate 1 911 and the arc plate 2 912 are opened at different positions, the rotating gears 914 on the fixed tubes 85 on both sides of the rotating plate 82 will rotate in different directions, thereby driving the sliding rod 86 and the splint 3 to rotate in different directions, so that the bottle cap and the bottle body of the plastic bottle are subjected to rotational forces in different directions, thereby separating the bottle cap from the bottle body.

[0053] At this time, the clamping plate 3 causes the magnetic block 96 to separate from the magnetic field range of the magnetic plate 2 99 and enter the magnetic field range of the magnetic plate 1 98 during the continuous movement. Since the magnetic plate 1 98 and the magnetic block 96 attract each other, the magnetic block 96 drives the fixing pin 93 to separate from the plastic bottle body and the bottle cap under the action of magnetic force. The clamping plate 3 contacts the guide plate 101 during the continuous movement. Under the push of the guide plate 101, the plastic bottle body and the bottle cap fall into the guide chute 102 and move in the guide chute 102 under the action of their own gravity. At this time, the bottle body falls into the first crushing chamber 51 through the guide chute 102, and the bottle cap falls into the filter bin 104 through the filter hole 103 during the movement. The bottom surface of the filter bin 104 is inclined, so that the bottle cap falling into the filter bin 104 falls into the second crushing chamber 52 through the through groove 105.

[0054] When the bottle body and the bottle cap enter the first crushing chamber 51 and the second crushing chamber 52 respectively, the staff drives the driving motor 64 to work, and the driving motor 64 drives the rotating shaft 53 to rotate. The rotation of the rotating shaft 53 drives the driving gear 62 arranged thereon to rotate. The rotation of the driving gear 62 drives the multiple driving gears 62 that mesh with each other to rotate synchronously, thereby driving the rotating shaft 53 and the crushing roller 55 located on the rotating shaft 53 to rotate, and the bottle body is crushed. When the driving gear 62 rotates, it drives the driving gear 2 63 that meshes with it to rotate, thereby driving the multiple driving gears 2 63 to rotate synchronously, and further drives the rotating shaft 2 54 and the crushing roller 55 located on the rotating shaft 2 54 to crush the bottle cap. The crushed materials are collected by the staff through the guide plate 56 and the discharge trough 57.
