Abstract
Description
Technical Field
[0001] This utility model relates to the field of biodegradable plastics technology, and specifically to a highly efficient and environmentally friendly biodegradable plastic foaming device. Background Technology
[0002] With the increasing severity of plastic pollution, the environmental damage caused by traditional plastic materials is becoming more and more prominent. Biodegradable plastics are gradually becoming an alternative as an environmentally friendly material. However, traditional production processes have problems such as high energy consumption and low efficiency. Therefore, the development of efficient and environmentally friendly biodegradable plastic foaming equipment can not only improve production efficiency, but also reduce the impact on the environment and promote sustainable development.
[0003] However, in actual use, the following shortcomings still exist. For example, existing biodegradable plastic foaming equipment cannot mold products of different shapes and cannot purify waste gas to meet environmental emission requirements. Because it cannot mold products of different shapes, enterprises can only produce biodegradable plastic products of limited specifications and shapes, which makes it difficult to meet the diverse needs of the market. For some emerging application fields, such as medical, construction, and automotive industries, there are stricter requirements for the shape and size of biodegradable plastic parts. The shortcomings of existing equipment limit the promotion and application of biodegradable plastics in these fields, hinder enterprises from entering new market areas, and are not conducive to the diversified development of enterprises and the improvement of market competitiveness. If the waste gas generated during the biodegradable plastic foaming process is discharged directly without purification, it will cause serious pollution to the atmospheric environment.
[0004] To address the aforementioned issues, this application proposes a highly efficient and environmentally friendly biodegradable plastic foaming device. Utility Model Content
[0005] This invention addresses the technical problems existing in the prior art by providing a highly efficient and environmentally friendly biodegradable plastic foaming device.
[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A high-efficiency and environmentally friendly biodegradable plastic foaming device, including a base plate, and further comprising:
[0007] A foaming assembly includes a first housing connected to a base plate, a first drive motor mounted on one side of the first housing, a screw connected to the output end of the first drive motor, a discharge port on the side of the first housing away from the first drive motor, a second drive motor mounted on the side of the base plate near the discharge port, a rotating head provided at the output end of the second drive motor, a circular die opening provided on the rotating head, a square die opening provided on the rotating head, and an irregularly shaped die opening provided on the rotating head;
[0008] An exhaust gas treatment assembly includes a second housing connected to a base plate near the side of a first housing. A connecting pipe is provided on the first housing, and the other end of the connecting pipe is connected to the second housing. A catalyst is disposed inside the second housing.
[0009] Preferably, a heating wire is provided inside the first housing, and a feed inlet is provided on one side of the top of the first housing.
[0010] After the material enters the first shell through the feed inlet, the heating wire is energized to generate heat, which raises the temperature inside the shell, thereby melting and plasticizing the material. The screw rotates under the drive of the first drive motor, pushing the material towards the discharge port. In this process, the material is conveyed, mixed and plasticized, preparing it for subsequent foaming and molding.
[0011] Preferably, the output end of the second drive motor is connected to a first limiting plate, and a rotating column is connected to the first limiting plate.
[0012] After the second drive motor starts, its output end drives the first limit plate to rotate, and the rotating column connected to the first limit plate rotates accordingly.
[0013] Preferably, a rotating seat is rotatably connected to the base plate, a limiting post is connected inside the rotating seat, and the rotating post is disposed on the limiting post.
[0014] The rotating column and the limiting column work together to transmit power to the rotating seat, which in turn drives the rotating head connected to the rotating seat to rotate, thereby achieving the switching of the mold opening.
[0015] Preferably, a second limiting plate is connected to the rotating seat, the second limiting plate is disposed on the first limiting plate, and the rotating head is connected to the second limiting plate.
[0016] The rotating seat is rotatably connected to the base plate, providing stable rotational support for the rotating head. The second limiting plate is fixedly connected to the rotating seat and fits tightly with the first limiting plate, effectively limiting axial movement during rotation and ensuring smooth operation of the rotating head.
[0017] Preferably, the first housing is provided with an exhaust gas outlet, the connecting pipe is connected to the exhaust gas outlet, a microbial layer is provided on the side of the second housing near the catalyst, and activated carbon is provided inside the second housing.
[0018] The waste gas generated during the foaming process enters the connecting pipe through the waste gas outlet, and then flows into the second shell. The waste gas first passes through the catalyst layer to decompose the harmful components, then passes through the microbial layer, where the degradation effect of microorganisms further purifies the waste gas. Finally, the residual odor and fine particles are removed through the adsorption effect of activated carbon, so as to achieve the standard emission of waste gas.
[0019] The beneficial effects of this utility model are:
[0020] Before the equipment starts working, the second drive motor is started, which drives the rotating die head to switch between round, square, or irregularly shaped dies as needed to form products of different shapes. After switching dies, the first drive motor drives the screw to rotate, conveying, mixing, and plasticizing the raw materials in the first housing. The foaming agent is also uniformly incorporated into the melt during this process. The plasticized material is extruded from the outlet to meet the production needs of different products such as sheets, pipes, and films. The waste gas generated during the foaming process enters the second housing of the waste gas treatment component through the connecting pipe. Under the action of the catalyst, the harmful components in the waste gas are decomposed, thereby purifying the waste gas and meeting environmental emission requirements. While ensuring efficient production, pollution is effectively reduced. Attached Figure Description

[0038] Working principle:
[0039] Before the equipment starts, the operator starts the second drive motor 27, whose output drives the first limit plate 28 to rotate.

The operator can switch between circular die opening 214, square die opening 215, or irregular die opening 216 as needed to meet the molding requirements of different shaped products. After the die opening is switched, the material enters the first housing 21 from the feed port 25. The heating wire 24 is energized to generate heat, raising the temperature inside the housing and melting and plasticizing the material. Simultaneously, the first drive motor 22 drives the screw 23 to rotate, pushing the material towards the discharge port 26. This process achieves material conveying and... During mixing and plasticizing, the foaming agent is also uniformly incorporated into the melt. The plasticized material is extruded from the outlet 26 and formed through the die on the rotating head 213 to meet the production needs of different products such as sheets, pipes, and films. The waste gas generated during the foaming process enters the connecting pipe 33 through the waste gas outlet 32 and then flows into the second shell 31. The waste gas first passes through the catalyst layer 34 to decompose the harmful components, then passes through the microbial layer 35, where the waste gas is further purified by the degradation effect of microorganisms.
