Description

Technical Field

[0001] The present invention relates to the field of plastic recycling and sorting, and in particular to a plastic recycling and sorting device and method. Background Art

[0002] Plastic recycling and sorting can separate different types and qualities of plastics from waste plastics, thereby achieving high-value utilization and reducing the harm of plastic pollution to the environment. Plastic bottles are one of the sources of plastic recycling. When recycling plastic bottles, since the material of the plastic bottle body and the material of the plastic bottle packaging are inconsistent, the two cannot be mixed and melted. The packaging skin on the plastic bottle needs to be torn off manually in advance. The existing technology uses manual processing of the packaging skin, which not only wastes time and manpower, but also produces some packaging skin residue, making the sorting efficiency low. Therefore, this application is proposed to address the above problems. Summary of the invention

[0003] In view of this, the technical problem to be solved by the present invention is to provide a plastic recycling and sorting device and method, which can perform a cyclic peeling process on plastic bottles to further improve the peeling efficiency of plastic bottles.

[0006] The upper end of the processing box is fixedly connected to two collecting boxes.

[0007] The lower end of the processing box is fixedly connected with a receiving box.

[0019] The present invention is described in detail with reference to the accompanying drawings in the embodiments of the present invention.

[0020] See also Figure 3-7 ,

[0021] A plastic recycling and sorting device includes a processing box 101, which is cylindrical. A peeling roller 201 is rotatably connected to the processing box 101 through a bearing. A plurality of friction teeth 202 are fixedly connected to the peeling roller 201 through bolts. Two revolving doors 102 are rotatably connected to the lower end of the processing box 101 through an axis. A plurality of groups of peeling brushes 103 are fixedly connected to the two revolving doors 102 through bolts. The axis of the peeling roller 201 is lower than the axis of the processing box 101. An opening 104 is provided above the processing box 101, and two air inlet ducts 107 are provided at the bottom of the processing box 101.

[0022] When using the sorting equipment, the staff first puts the plastic bottles into the opening 104 above the processing box 101, and then drives the peeling roller 201 to rotate through an external drive motor. Since the axis of the peeling roller 201 is lower than the axis of the processing box 101, when the plastic bottles are piled up downward, the multiple friction teeth 202 on the surface of the peeling roller 201 and the multiple groups of peeling brushes 103 on the two revolving doors 102 cooperate to rub the surface of the plastic bottles, thereby tearing the plastic packaging skin on the surface of the plastic bottles, and when the peeling roller 201 continues to rotate, the plastic bottles can be continuously cyclically rubbed, thereby achieving comprehensive peeling treatment, so that the plastic bottle body and the packaging skin are completely separated.

[0023] During the peeling process of the plastic bottles, the two air inlet pipes 107 are connected to the fan, and the fan is used to blow air through the two air inlet pipes 107, so that the detached plastic skin can be discharged through the opening 104 along the air flow, while the plastic bottle body remains in the processing box 101, thereby realizing the function of separating the plastic body from the packaging skin. Compared with the conventional manual peeling method, it has the effect of saving time and manpower, and further improving the sorting efficiency.

[0024] See also Figure 1-2 ,

[0025] A guide plate 105 is fixedly connected to the upper end of the processing box 101 by bolts. The guide plate 105 guides the blown packaging skin, so that the packaging skin is discharged through the gap formed between the guide plate 105 and the opening 104, thereby preventing the packaging skin from being scattered everywhere after being blown out.

[0026] See also Figure 8 ,

[0027] Two collecting boxes 106 are welded on the upper end of the processing box 101. The two collecting boxes 106 collect the packaging skins. The packaging skins discharged through the opening 104 can automatically fall into the two collecting boxes 106, which is convenient for the staff to centrally process the packaging skins.

[0028] See also Figure 3-4 ,

[0029] The lower end of the processing box 101 is fixedly connected to the receiving box 401 by bolts. The receiving box 401 is used to receive the peeled plastic bottle bodies. When the peeling of the plastic bottle bodies is completed, the staff controls the two revolving doors 102 to rotate and open, and the plastic bottle bodies in the processing box 101 fall into the receiving box 401, realizing the function of collecting plastic bottles.

[0030] See also Figure 4 ,

[0031] The upper end of the receiving box 401 is fixedly connected to two hydraulic cylinders 301 by bolts, the lower ends of the two revolving doors 102 are welded with arc-shaped slot frames 301, and the moving ends of the two hydraulic cylinders 301 are welded with sliding rods, which are slidably connected in the two arc-shaped slot frames 301 respectively.

[0032] When the plastic bottle bodies need to be unloaded, the two hydraulic cylinders 301 are controlled to retract their moving ends, and the two slide bars slide in the two arc-shaped slot frames 301 respectively, and at the same time can pull the two revolving doors 102 to rotate, thereby realizing the function of unloading the plastic bottles.

[0033] See also Figure 4 ,

[0034] The moving ends of the two hydraulic cylinders 301 are fixedly connected with the squeezing plates 304 by bolts. When the moving ends of the two hydraulic cylinders 301 shrink and open the two revolving doors 102, the two squeezing plates 304 move away from each other, and the plastic bottle body falls in the middle position of the two squeezing plates 304. When the two revolving doors 102 are closed again, the two squeezing plates 304 approach each other, and then the plastic bottle in the middle of the two squeezing plates 304 can be squeezed, so that the air in the plastic bottle body is discharged, thereby reducing the occupied space, and the squeezed plastic bottle compression block gradually becomes larger. After the volume of the compression block reaches the requirement, it is convenient for the staff to carry the plastic bottle as a whole.

[0035] See also Figure 8 ,

[0036] The receiving box 401 is rotatably connected with a discharge door 402 via a bearing. When the volume of the compressed block reaches the required value, the staff will open the discharge door 402 to facilitate the removal of the compressed block.

[0037] See also Figure 1-2 ,

[0038] The plurality of friction teeth 202 are all made of rubber material. The friction teeth 202 made of rubber material can increase the friction force between the rubber teeth and the plastic bottles, thereby facilitating continuous rolling of the plastic bottles in the processing box 101, thereby facilitating the peeling process.

[0039] See also Figure 7 ,

[0040] The multiple groups of peeling brushes 103 are all steel wire brushes, which have good strength and wear resistance and can extend the service life of the peeling brushes 103.

[0041] A method of using a plastic recycling sorting device, the method comprising the following steps:

[0042] Step 1: Put the plastic bottle into the processing box 101 through the opening 104 above, and drive the peeling roller 201 to rotate through the external drive motor;

[0043] Step 2: The multiple friction teeth 202 on the surface of the peeling roller 201 cooperate with the multiple groups of peeling brushes 103 on the two rotating doors 102 to continuously peel the plastic bottles;

[0044] Step 3: Use a fan to blow air through the two air inlet pipes 107, and the separated plastic skin is discharged through the opening 104 along the air flow, so that the plastic body is separated from the packaging skin;

[0045] Step 4: The two revolving doors 102 are rotated and opened, and the plastic bottle bodies in the processing box 101 fall into the receiving box 401;

[0046] Step 5: The two revolving doors 102 are closed again, and the two squeezing plates 304 are moved closer to each other to squeeze the plastic bottle between the two squeezing plates 304 .
