Description

Technical Field

[0001] The utility model relates to the technical field of foam recovery processing, in particular to a small crushing and extruding device for foam recovery. Background Art

[0002] In logistics, express delivery, and in places like shopping malls and supermarkets where foam packaging is used extensively, foam waste often takes up considerable space. Recycling stations like these can use small crushing and extrusion devices to shred and compress this foam packaging material, reducing its volume for easier storage and transportation. The resulting compressed blocks can then be sold to recycling companies for further processing. Foam materials are widely used for packaging and protection in the production of home appliances and electronic products. These companies can install foam recycling equipment within their production workshops to immediately process the large amounts of foam waste generated during production. The equipment breaks down and compresses the foam into blocks, making them easier to recycle within the company or resell to specialized foam reprocessing companies, reducing waste accumulation and saving storage space.

[0035] A fixing ring 20 is fixedly connected to the inside of the right side of the compression tube 3, so that the compression tube 3 can provide support for the fixing ring 20, and a plurality of fixing rods 21 are fixedly connected to the left side of the fixing ring 20, so that the fixing ring 20 can provide support for the plurality of fixing rods 21.

One end of the spring 22 is fixedly connected to the right side of the filter plate 23, and the other end of the spring 22 is fixedly connected to the left side of the fixing ring 20, so that when the filter plate 23 is squeezed, it will squeeze the spring 22, and the outside of the extrusion plate 19 contacts the inner wall of the compression tube 3, and the outside of the filter plate 23 contacts the inner wall of the compression tube 3.

[0036] Working Principle: After the foam is crushed, the device activates heating rods 16, evenly distributed on the left and right inner walls of the containment tube 4. These rods begin to heat the crushed foam. Once the temperature reaches the foam's melting point, the crushed foam gradually melts into a molten state. This process continues until the entire foam material is heated and uniformly molten.

[0037] To prevent molten foam from clogging during discharge, the discharge system at the bottom of the holding tube 4 is activated. Rotating shaft 2 13, through a transmission system, drives multiple discharge plates 15 to rotate. These plates 15 maintain close contact with the bottom inner wall of the holding tube 4, ensuring that the molten foam can be smoothly discharged from the holding tube 4 and into the compression tube 3. The rotation of the discharge plates 15 effectively prevents foam from clogging the discharge port, improving material fluidity.

[0038] After the molten foam material enters the compression tube 3 from the receiving tube 4, motor 2 18 is activated. The output shaft 2 24 of motor 2 18 rotates the extrusion plate 19 through the transmission assembly. The rotation of the extrusion plate 19 pushes the molten foam material toward the end of the compression tube 3. As the extrusion plate 19 continues to rotate, the molten foam is gradually pushed toward the filter plate 23 within the compression tube 3.

[0039] When the molten foam material is pushed to the end of the compression tube 3 by the extrusion plate 19, the filter plate 23 plays a key role. The filter plate 23 is connected to the right side of the compression tube 3 via a retaining ring 20 and multiple retaining rods 21. The retaining rods 21 are equipped with springs 22, which provide elastic support for the filter plate 23. As the extrusion plate 19 continues to advance, the molten foam begins to squeeze the filter plate 23. The compressive force pushes the filter plate 23 rightward, compressing the springs 22.

[0040] As the spring 22 is compressed to a certain degree, the filter plate 23 begins to work under the pressure of the molten foam, further compressing the foam and squeezing it out through its tiny filter holes. This process not only compresses the volume of the foam, but also filters the foam material, ensuring that the molten foam that finally passes through the filter plate 23 has uniform density and consistent quality.

[0041] When the filter plate 23 squeezes the foam material and discharges it through its filter holes, the restoring force of the spring 22 begins to take effect, and the filter plate 23 gradually returns to its initial position. At this time, the extrusion plate 19 will continue to push the molten foam material forward, continuing to perform new foam compression and extrusion work, and the whole process is repeated.

[0042] Finally, the foam material extruded through the filter plate 23 is output from the end of the compression pipe 3 to form a processed compressed foam block.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
