Description

Technical Field

[0001] The utility model relates to the field of resin production, and more specifically, to a resin flake crushing device. Background Art

[0002] In the resin production process, after the resin solidifies, larger resin sheets will be formed. The larger resin sheets need to be cut and crushed into small resin sheets to facilitate the packaging and transportation of the resin sheets. When crushing the resin sheets, a crushing device is needed to crush the larger resin sheets. The existing crushing device generally cuts the resin sheets by a cutting blade, but the existing crushing device cannot cut the resin sheets according to production needs, which makes it inconvenient for the crushing device to crush the resin sheets for production. At the same time, when the existing crushing device cuts the resin sheets, the resin sheets are easily adhered to the support seat used for cutting and crushing, which makes it inconvenient to extract the crushed resin sheets after crushing the resin sheets, thereby making it inconvenient to crush and produce the resin sheets.
