Multi-layer material arc-shaped cutting method

Abstract

The invention relates to the field of disposable hygienic products, in particular to a multi-layer material arc-shaped cutting method which comprises the following steps that firstly, multi-layer materials are input in a stacked mode, hot pressing is conducted on the two sides of the multi-layer materials through a hot pressing device, and it is guaranteed that the multi-layer materials are mutually bonded and not separated through hot pressing; secondly, the materials are conveyed through a first adsorption conveying device and then fed into an arc cutting device to be subjected to arc cutting; and thirdly, waste obtained after arc cutting is sucked away through a waste suction nozzle, the waste suction nozzle is arranged below the arc cutting device, the multi-layer material obtained after arc cutting is transferred through a transfer wheel device, and then lengthened conveying is conducted through cooperation of a second adsorption conveying device and the transfer wheel device. The arc-shaped cutting method solves the technical problems that when an existing arc-shaped cutting device conducts arc-shaped cutting on multiple layers of materials, a material layer which is not attached to an adsorption bottom roller is prone to loosening or rolling up, the cutting effect is poor, and waste enters a product main line.

Description

technical field [0001] The invention relates to the field of disposable sanitary products, in particular to an arc-shaped cutting method for multi-layer materials. Background technique [0002] At present, the applicant’s Chinese patent application number: CN201620627650.3 discloses an arc-cut knife holder mechanism, including a knife holder, a knife holder base, an upper roller and a lower roller, and the knife holder is detachably placed on the upper end of the knife holder base. Both ends of the upper roller are fitted with the first bearing seat, and the two first bearing seats are respectively placed in the frame bodies on both sides of the tool holder; arc cutters are arranged on the roller body of the upper roller; both ends of the lower roller are fitted with The second bearing seat, the two second bearing seats are respectively placed in the frame bodies on both sides of the knife rest, and the lower roller is at the lower end of the upper roller; the two first bear...

Problems solved by technology

[0004] Therefore, in view of the above-mentioned problems, the present invention proposes a multi-layer material arc cutting method, which solves the problem that the existing arc cutting device is easy to cause the material layer not close to the adsorption bottom roller when performing arc cutting of multi-layer materials. Slack or rollover, resulting in poor cutting effect and technical problems of waste entering the main line of the product
