Description

Technical Field

[0001] The invention relates to the technical field related to self-adhesive sticker recycling, and in particular to an automatic screening and compression device for self-adhesive sticker recycling. Background Art

[0002] Self-adhesive labels, also known as self-adhesive label materials, are a composite material made of paper, film or special materials as the surface, with adhesive coated on the back and silicone-coated protective paper as the base paper. Paper self-adhesive labels are mainly used on liquid washing products and popular personal care products; film materials are mainly used on mid-to-high-end daily chemical products. At present, popular personal care products and household liquid cleaning products account for a large proportion on the market, so the corresponding paper materials are used more. With the development of the market, the recycling of self-adhesive products is becoming more and more extensive, and paper self-adhesive waste is also easy to recycle. Waste self-adhesive paper can be made into environmentally friendly shopping bags, bookmarks, labels and other daily necessities. Waste self-adhesive paper can also be made into candy bags, jeans, clothes, etc., and can also be used as fuel for the production of low-temperature charcoal, hot water boilers, etc., so the recycling of self-adhesive waste is becoming more and more common. In the process of processing self-adhesive waste, the self-adhesive waste is crushed, then screened and impurities are removed, and then compressed to obtain flocculent self-adhesive products, which is more convenient for later processing. Therefore, an automatic screening and compression equipment for self-adhesive recycling is needed.

[0003] However, with the existing automatic screening and compression equipment for self-adhesive recycling, most of the self-adhesive waste is collected from various places. When these self-adhesive wastes are crushed, some iron filings and impurities will be mixed in them. This impurity will seriously affect the reprocessing of the self-adhesive wastes. Moreover, most of the crushing and recycling devices cannot completely crush some of the self-adhesive wastes when processing the self-adhesive, which will also increase the workload of reprocessing. At the same time, the self-adhesive waste contains both plastic and paper materials, and a single crushing requires further processing of the waste.

[0004] In order to solve the above problems, after searching, the "A crushing and centralized recycling device for self-adhesive fabrics" proposed in the announcement number "CN112536094A" proposes that "by setting a feeder, the feeder can be used to facilitate workers to load materials and reduce the workload of workers. By setting a vibration motor, the vibration motor generates vibration to drive the self-adhesive fabric residues that are initially crushed inside the double-axis crusher to slide out along the discharge bin, which is conducive to subsequent secondary crushing and ensures the recycling effect. By setting an inclined platform, it is convenient for the subsequent storage hopper to be transported and used, which is conducive to the storage of materials. The bucket pushes the crushed self-adhesive fabric residue up and down, and by setting up a blower, the blower is used to blow the crushed self-adhesive fabric residue to the storage hopper inside the storage bin, which is convenient for subsequent centralized transportation and recycling, and ensures the subsequent recycling efficiency. "The article proposes to use a feeder to transport, and a vibrating motor and a crusher to screen the self-adhesive waste. However, the self-adhesive waste usually adheres to some iron filings and impurities. Such impurities mixed together will seriously affect the reprocessing of the self-adhesive waste. A single screening structure is obviously insufficient.

[0005] In view of this, an in-depth study was conducted on the above-mentioned issues, which led to the present case. Summary of the invention

Such impurities will seriously affect the reprocessing of the self-adhesive waste materials. Moreover, when most crushing and recycling devices process self-adhesive stickers, some self-adhesive waste materials cannot be completely crushed, which will also increase the workload of reprocessing.

[0040] Working principle: An automatic screening and compression device for recycling adhesives. When in use, first put the adhesive waste to be recycled into the feed port 201, and then drop into the crushing bin 202 below through the feed port 201. At the same time, the first drive motor 205 is started to drive the crushing blade 204 at one end of the first connecting shaft 203 to rotate. The two sets of crushing blades 204 rotate in opposite directions under the meshing connection of the first gear plate 206 to crush the adhesive waste, and then the crushed adhesive waste falls into the screen below. 208, then start the vibration motor 209, drive the screen 208 to shake at one end of the spring 207, screen out the adhesive waste that meets the size, and the screened adhesive waste will fall onto the conveyor belt 301 below. At this time, turn on the second drive motor 306, and drive the second gear plate 304 at both ends of the second connecting shaft 305 to rotate through the second drive motor 306. The second gear plate 304 drives the conveyor belt 301 to rotate through the gear slot 302, and the three sets of sprockets 307 are connected on the chain. Driven by the conveyor belt 308, the conveyor belt 301 rotates synchronously. When the crushed self-adhesive waste is transported, the third driving motor 7 is started to drive the steel brush 6 at one end of the third connecting shaft 4 to rotate, so that the steel brush 6 combs and spreads the self-adhesive waste. Secondly, the soft magnetic patch 303 will adsorb the iron filings impurities contained in the self-adhesive waste on the surface of the conveyor belt 301. The self-adhesive waste after impurities removal will fall into the conveying bin 801 through one end of the conveyor belt 301, and then the waste will be pushed into the dissolving tank below through the push plate 807. In the bin 810, the hydraulic cylinder 805 drives the pressing plate 802 to the opening of the dissolving bin 810, and then the required solvent is injected through the water inlet pipe 811 and the solvent inlet 812 to dissolve the self-adhesive waste and separate the paper material and the plastic. After the plastic material is melted, it is extracted by the high-pressure pump 814, and the paper material is squeezed by the pressing plate 802. In this way, the self-adhesive waste can be well screened for the second time, and different raw materials can be obtained. In this way, an automatic screening and compression equipment for self-adhesive recycling is completed.
