Description

Technical Field

[0001] The utility model relates to a slider mechanism, in particular to a cutting knife slider mechanism for a cutting bed. Background Art

[0002] On a cutting table, a cutting knife is generally arranged at the lower end of a cutting knife fixing rod, and the cutting knife fixing rod is inserted into the slide groove of a sliding connection seat, and the upper end of the cutting knife fixing rod is connected to an up-and-down reciprocating motion mechanism. During operation, the cutting knife realizes a rapid up-and-down reciprocating motion through the up-and-down reciprocating motion mechanism, and at this time, the cutting of the fabric on the cutting table can be completed by controlling the motion path of the cutting knife. Since there is a high-speed sliding motion between the current cutting knife fixing rod and the sliding connection seat, the contact area between the two is large, and high-precision sliding cooperation is required. The current cutting knife fixing rod or the sliding connection seat will wear out faster during the high-speed reciprocating motion, and when the wear occurs, a large noise will be generated. The current solution to the above-mentioned wear and noise problems is to use more expensive and wear-resistant materials to manufacture the cutting knife fixing rod and the sliding connection seat, but the upper and lower ends of the cutting knife fixing rod and the outside of the sliding connection seat will not generate friction, which causes unnecessary waste and also greatly increases the production cost of parts.

The utility model improves the original surface friction into line friction, thereby reducing the noise generated during the movement of the mechanism, reducing mechanical wear, and having a long service life and stable operation.
