Description

Technical Field

[0001] The utility model belongs to the technical field of plastic recycling, and in particular relates to a plastic crushing and recycling device. Background Art

[0002] As a widely used material, plastic has serious environmental problems due to its difficult-to-decompose properties. Plastic products take hundreds of years to degrade in the natural environment, and in landfills, they occupy a lot of land and may pollute soil and groundwater. In addition, if plastic is incinerated, it may release toxic substances such as dioxins, causing serious pollution to the atmosphere. Therefore, recycling plastics can reduce the emission of these pollutants and reduce the burden on the environment.

[0003] Plastics need to be crushed during the recycling process to facilitate subsequent reprocessing. Since plastic plates or other plastic products will generate a lot of waste during the processing, the conventional crusher cannot crush the plastic waste evenly at one time due to the different sizes of the waste. Therefore, a plastic crushing and recycling device with a multi-stage crushing mechanism is needed. Utility Model Content

[0004] In order to solve the problem that conventional crushers cannot crush plastic waste evenly at one time during operation, the utility model provides a plastic crushing and recycling device, and the technical solution is as follows:

[0005] A plastic crushing and recycling device comprises a frame, a rolling mechanism, a crushing mechanism and a collecting trough. The frame is provided with the rolling mechanism, the crushing mechanism and the collecting trough in sequence from top to bottom; and a feeding hopper is provided on the top of the crushing mechanism.

[0006] Preferably, the rolling mechanism includes a mechanical arm and a spherical rolling head; one end of the mechanical arm is fixedly connected to a side wall of the frame, and the other end is connected to the spherical rolling head via a fixed bearing.

[0007] Preferably, the crushing mechanism includes a screening net, a rotating shaft, a flat knife, a discharge hopper, a accommodating chamber and a driving motor; the screening net is a funnel-shaped structure; the rotating shaft passes through the middle of the screening net and forms a rotatable connection with the screening net; a plurality of flat knives are provided at one end of the rotating shaft close to the discharge hopper.

[0008] Preferably, the discharge hopper is a funnel-shaped structure, and a circular opening is provided in the middle of the discharge hopper.

[0009] Preferably, one side of the driving motor is fixed on a side wall in the middle of the frame.

[0010] Preferably, a collecting trough is provided at the bottom of the pulverizing mechanism, and the collecting trough is a drawer-type structure.

[0011] Compared with the prior art, the utility model provides a plastic crushing device with the following beneficial effects: the utility model adopts a multi-stage crushing mechanism, firstly using the spherical crushing head on the robotic arm to crush the plastic for pre-treatment, and then using a driving motor to drive the rotating shaft and the flat knife to further finely crush the crushed plastic particles, ensuring that the plastic waste can be efficiently and evenly crushed.

[0015] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0016] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0017] In this embodiment, refer to Figure 1 and Figure 2 A plastic crushing and recycling device is specifically implemented, including a frame 1, a crushing mechanism, a crushing mechanism and a collecting trough 10. The frame 1 is provided with a crushing mechanism, a crushing mechanism and a collecting trough 10 in sequence from top to bottom; a feeding hopper 4 is provided on the top of the crushing mechanism.

[0018] In this embodiment, the rolling mechanism includes a mechanical arm 2 and a spherical rolling head 3; one end of the mechanical arm 2 is fixedly connected to a side wall of the frame 1, and the other end is connected to the spherical rolling head 3 through a fixed bearing; the mechanical arm 2 can perform reciprocating motion or rotational motion; the spherical rolling head 3 rolls the input plastic material, and due to its spherical shape, the material can be squeezed at multiple angles during the rolling process, thereby improving the rolling efficiency.

[0019] In this embodiment, the crushing mechanism includes a screening net 5, a rotating shaft 6, a flat blade 7, a discharge hopper 8, a receiving chamber 9 and a driving motor 11; the screening net 5 is a funnel-shaped structure, which is used to separate the plastic particles and the plastic pieces that are not fully crushed during the crushing process, ensuring that only the plastic particles that reach a certain size can pass through the screening net 5;

[0020] The rotating shaft 6 passes through the middle of the screening net 5 and is rotatably connected to the screening net 5; a plurality of flat knives 7 are provided at one end of the rotating shaft 6 close to the discharge hopper 8; the rotating shaft 6 is driven by the driving motor 11 to drive the flat knives 7 provided thereon to rotate, thereby crushing the plastic after rolling.

[0021] The discharge hopper 8 is a funnel-shaped structure, and a circular opening is provided in the middle of the discharge hopper 8 to discharge the crushed plastic particles into the collecting tank 10 .

[0022] A collecting trough 10 is provided at the bottom of the pulverizing mechanism. The collecting trough 10 is a drawer-type structure. The collecting trough 10 is used to collect the pulverized plastic particles discharged from the discharge hopper 8 .

[0023] One side of the driving motor 11 is fixed on a side wall in the middle of the frame 1; the driving motor 11 provides power for the crushing mechanism to drive the rotating shaft 6 and the flat knife 7 to rotate.

[0024] The working principle of the utility model is as follows: during operation, the plastic to be crushed is first put into the hopper 4. As the mechanical arm 2 rotates, the spherical crushing head 3 performs preliminary crushing treatment on the plastic. The crushed plastic particles are screened by the screening net 5. The smaller particles will enter the accommodating chamber 9 through the screening net 5 after the pre-treatment of crushing. After the drive motor 11 is started, the rotating shaft 6 starts to rotate, driving the flat knife 7 to further crush the crushed plastic particles. The crushed plastic particles enter the collection trough 10 of the drawer structure through the discharge hopper 8. When the plastic particles in the collection trough 10 reach a certain amount, the operator can simply pull out the collection trough 10 like a drawer, pour out the plastic particles or perform other treatments, and then push them back into the device again to continue the crushing and recycling process.

[0025] The above contents are further detailed descriptions of the present invention in combination with specific further embodiments, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as the protection scope of the present invention.
