Description

Technical Field

[0001] The utility model relates to the technical field of embroidery machines, in particular to a cloth clamping device. Background Art

[0002] Before embroidery, the fabric on the embroidery machine needs to be fixed to the embroidery frame with a cloth clip. Traditional cloth clips are manual cloth clips, which are clamped and removed manually when in use. One embroidery frame requires multiple cloth clips, so the use of manual cloth clips has problems such as cumbersome and laborious operation and the fabric is easy to loosen. Utility Model Content

[0003] In order to solve the above problems, the utility model provides a cloth clamping device, comprising:

[0010] Furthermore, the inflatable and deflable airbag includes an inflated expansion state and a pressure relief state. When the inflatable and deflable airbag is in the pressure relief state, the fabric clamp is clamped on the fabric clamping protrusion by the second clamping arm and the elastic material clip; when the inflatable and deflable airbag is in the inflated expansion state, the free end of the reset spring sheet pops off the clamping piece, and the entire fabric clamp pops up and leaves the fabric clamping protrusion under the reaction force of the reset spring sheet.

[0011] Furthermore, a convex tooth is provided on the surface of the fabric clamping protrusion, and an engaging groove is provided on the bottom of the second clamping arm. When the inflatable and deflated airbag is in a pressure-releasing state, the engaging groove meshes with the convex tooth.

[0012] Furthermore, the elastic material clip includes a U-shaped groove, a connecting portion and an arc-shaped outer flange. The U-shaped groove is fixedly connected or integrally formed with the arc-shaped outer flange through the connecting portion. The U-shaped groove covers the clamping connection seat and the first clamping arm. One side of the U-shaped groove is fixed in the mounting groove and is detachably fixedly connected to the second clamping arm. When the elastic material clip loses its elastic force, it is easy to replace. The arc-shaped outer flange is close to the fabric clamping protrusion.

[0017] The beneficial effect is that when the present application is used, the inflatable airbag is first inflated with an inflating device to put the inflatable airbag in an inflated state, at which time the free end of the reset spring sheet pops off from the clamping piece, and the entire fabric clamp pops up and leaves the fabric clamping protrusion under the reaction force of the reset spring sheet, and then the fabric is placed on the fabric clamping protrusion, and then the inflatable airbag and the fabric clamp are pressed downward by hand to put the inflatable airbag in a depressurized state, at which time the convex teeth on the surface of the fabric clamping protrusion and the bite groove at the bottom of the second clamping arm mesh the fabric, and at the same time the elastic material clip and the fabric clamping protrusion clamp the fabric, such as This can ensure the stability of fabric clamping and prevent the fabric from loosening easily. The device is simple and convenient to use and can quickly complete the fabric clamping operation without damaging the fabric. It effectively solves the problem of time-consuming, labor-intensive and inefficient manual fabric clamping operation in the prior art. In addition, after the fabric clamp clamps and fixes the fabric on the fabric clamping convex portion, since the inflatable and deflated airbag is in a pressure relief state, even if the inflatable and deflated airbag and the inflation pipeline leak during the later embroidery process, it will not affect the clamping and fixing effect of the fabric clamp on the fabric. It can also effectively prevent the inflatable and deflated airbag from being in an inflated state for a long time, affecting its service life. BRIEF DESCRIPTION OF THE DRAWINGS
