Abstract

The invention relates to a non-woven fabric fixture applied to a non-woven fabric automatic sewing shoe cover machine, and in particular relates to a fixture driven by an elastic potential energy mode and external force, belonging to the technical field of textile machinery. The fixture can be located, clamped and loosened by virtue of a stepping motor in a mode of combining a synchronous belt and a threaded drive hoisting mechanism, and on the basis of the characteristic that rectangular threaded driving has a self-locking function, the fixture, under a circumstance of clamping a gray non-woven fabric, can keep a clamping status without external force; when loosened, driven by the potential energy of the spring, the fixture under a folded status can be rapidly expanded through the potential energy of the spring so as to push a connecting mechanism which is used for connecting an upper clamping plate and a lower clamping plate to move to the front end of the fixture in the direction of a linear guide way, and the lower clamping plate has a constant slope, so that the stress situation of the lower clamping plate is improved and a problem that the front end of the lower clamping plate becomes warped caused by the self-weight of the lower clamping plate of the fixture and an excessively long cantilever is avoided; and the fixture can fundamentally keep the upper and lower clamping plates under a seamless fitted status with the gray non-woven fabric constantly.

Description

technical field

[0001] The invention relates to a non-woven fabric clamp used on a non-woven fabric automatic sewing shoe cover machine, specifically a clamp driven by elastic potential energy and external force, and belongs to the technical field of textile machinery. Background technique

[0002] Existing non-woven fabric automatic sewing shoe cover machine needs a kind of clamp that is adapted to it when working. The disadvantages of the clamp mentioned in the Chinese invention patent (patent application number: 201410263945.2) are: it cannot solve the bending of the lower splint that will occur during long-term use due to the excessive length of the lower splint, resulting in the inability to completely clamp the non-woven fabric. The cloth problem; the magnetic force generated by the electromagnet in the process of absorbing the lower splint will produce an adsorption force with the iron overlock sewing machine workbench, which needs to be demagnetized or shielded to af...
