Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric processing, in particular to a non-woven fabric trimming device. Background Art

[0002] Non-woven fabric, also known as non-woven fabric, is a sheet, web or pad made of directional or randomly arranged fibers, which are combined with each other by friction, adhesion or bonding, or a combination of these methods. After processing, the non-woven fabric needs to be cut and trimmed to obtain a non-woven fabric with neat edges.

[0003] A non-woven fabric trimming device disclosed in the publication number CN218291401U includes a mounting bracket, a driving cylinder, a transmission bracket, a mounting shell and a trimming seat, a connecting rod is arranged at the bottom of the driving cylinder, and the transmission bracket is installed at the bottom of the connecting rod; the mounting shell is installed on the transmission bracket, a bevel cutter is arranged on the mounting shell, and an inclined blade is arranged at the bottom of the bevel cutter, the trimming seat is arranged on the mounting bracket and is located below the bevel cutter, a trimming shell is installed on the trimming seat, and a cutting groove matching the bevel cutter is formed between the trimming shell and the cutting seat. The driving cylinder drives the mounting shell on the driving bracket, and the bevel cutter on the mounting shell descends toward the trimming seat, so that the bevel cutter cuts the non-woven fabric along the cutting groove through the inclined blade, completing the trimming of the non-woven fabric, replacing manual trimming, and greatly improving the work efficiency. The inclined blade added in the present design is inclined to reduce the blade angle, which is convenient for cutting.

[0004] Although the above nonwoven fabric trimming device solves certain problems, it still has the following disadvantages:

[0005] (1) The trimming device drives the blade to move up and down by the cylinder to perform trimming operation on the non-woven fabric, but the non-woven fabric needs to be rolled up additionally after trimming, and the production and processing efficiency of the non-woven fabric is low.

[0006] (2) The non-woven fabric cutting device requires manual control of the position of the non-woven fabric cutting edge. Inaccurate cutting can easily lead to uneven non-woven fabric after cutting, thus affecting the quality of the non-woven fabric. Utility Model Content
