Description

Technical Field

[0001] The utility model relates to the technical field of paper printed products, in particular to a paper printed product edge trimming and dust removal device. Background Art

[0002] In the production process of paper printed products, in order to make the edges of the paper printed products more neat, it is usually necessary to perform edge trimming on the paper printed products. Currently, edge trimming machines are generally used to perform edge trimming on paper printed products.

[0003] For example, a Chinese patent (publication number: CN217728948U) discloses a trimming dust suction device, which relates to the technical field of packaging paper production equipment. A trimming dust suction device includes a cutting machine body, on which a dust suction assembly is installed, and the dust suction assembly includes a mounting rod horizontally fixed to the cutting machine body, a dust suction pipe arranged on the mounting rod, a paper suction port connected to the dust suction pipe, a branch pipe connected to the dust suction pipe at one end, a dust suction nozzle installed at one end of the branch pipe, and a dust suction fan installed at one end of the dust suction pipe; the paper suction port is aligned with the cutting edge falling position to suck the edge waste paper into the dust suction pipe, and the dust suction nozzle is aligned with the cutting position to suck the cutting dust into the dust suction pipe. This application has the effect of timely cleaning the edge waste and cutting dust generated by trimming, thereby improving the cleanliness of the packaging paper trimming process.

[0004] The above-mentioned edge trimming dust suction device still has certain shortcomings. By setting a filter assembly and a paper pushing assembly, after the edge waste paper and cutting dust generated by edge trimming enter the dust suction pipe, the edge waste paper is blocked by the filter net, and the cutting dust continues to pass through the filter net under the action of suction. The blocked edge waste paper falls into the paper collecting box for collection under the action of its own weight and the paper pushing assembly. However, the edge waste paper is easily blocked by the filter net under the action of suction, resulting in the dust suction fan being unable to effectively suck the subsequent edge waste paper into the dust suction pipe, affecting the dust removal effect of the edge waste paper and dust. Therefore, the present application proposes a paper print edge trimming dust removal device to solve the above-mentioned problem. Utility Model Content

The first bevel gear 304 drives the second bevel gear 305 and the rear end threaded rod 306 to rotate together. The rear end threaded rod 306 drives the rear end sprocket to rotate. The rear end sprocket drives the front end sprocket and the front end threaded rod 306 to rotate together through the chain. Since the two sections of the threaded rod 306 have opposite directions, the threaded rod 306 rotates to drive the two moving plates 308 to move in opposite directions at the same time. The moving plates 308 slide on the outer surface of the sliding rod to increase the stability of the moving plates 308 when moving. When the moving plates 308 move, the connecting block 310 and the second cross plate 311 are driven to move together through the first cross plate 309. The first cross plate 309 and the second cross plate 311 move together to drive the multiple scrapers 312 to move to clean the filter 5, prevent dust and debris from blocking the filter 5, and improve the dust collection effect.

[0045] (2) When the trimmer 1 is working, the fan 404 is started, and the fan 404 sucks dust and waste into the second suction pipe 402 through the multiple first suction pipes 401, and sends the dust and waste in the second suction pipe 402 to the box 2 for storage. The dust and waste will remain in the box 2 under the action of the filter 5, and the excess air will enter the third suction pipe 403 and finally be discharged from the air outlet 405, so as to facilitate the collection of dust and waste.
