Chopping block type scissor for loom for shearing fabric in chopping manner

Abstract

The invention relates to a chopping block type cutter device used on a loom and adopting the chopping means to cut fabrics. A cutter cam (5) is arranged on a detection shaft (4) in the cutter device of the loom, a bearing (8) and a moving blade seat (3) are disposed on an eccentric shaft (9), and the bearing (8) is in contact with the cutter cam (5); a blade (10) is arranged on the moving blade seat (3), and a blade fixed platen (11) and a blade platen (13) are disposed at both sides of the blade (10); a spring (2) and a gyration central shaft (14) of the moving blade seat are also arranged on the moving blade seat (3); a PU rubber pad (6) and a chopping block type bracket (7) are arranged on a stationary blade seat (1), and the stationary blade seat (1) is fixed on the loom; the stationary blade seat (1) is connected with the moving blade seat (3) through the spring (2) and the gyration central shaft (14) of the moving blade seat, and a nylon sleeve (12) is disposed on the gyration central shaft (14) of the moving blade seat between the stationary blade seat (1) and the moving blade seat (3). The device effectively avoids the slippage of fabrics at the cutting edge of the blade in the process of cutting, extends the service life of the blade, and reduces the amount of usage of the blade.

Description

technical field [0001] The invention belongs to a part of a loom, and in particular relates to a chopping board type scissors device for a loom that cuts fabrics in a chopping manner, especially suitable for special fabrics that are difficult to cut with ordinary scissors. Background technique [0002] As everyone knows, the common scissors device of loom is usually made up of moving blade seat, static blade seat, blade pressing plate, blade fixing plate, two blades, scissors cam, spring etc. When the loom is running, it drives the scissors cam to run, and the scissors cam drives the moving blade seat and the blade to move, and the cutting edge of the blade crosses with the edge of another blade installed on the static blade seat to complete the cutting process. When the scissors device is cutting special fabrics such as glass fiber roving (aggregate made of parallel filaments or parallel monofilaments without twisting and merging), it often cannot cut the fabric well, and t...

Problems solved by technology

When the scissors device is cutting special fabrics such as glass fiber roving (aggregate made of parallel filaments or parallel monofilaments without twisting and merging), it often cannot cut the fabric well, and the weft yarn cannot be cut well during the cutting process. Problems such as medium slippage and fast wear of scissors
