Description

Technical Field

[0001] The utility model relates to a needle guard plate device. Background Art

[0002] The original needle guard on the embroidery machine cannot move. The current needle guard has been tilted up to match the seam head to prevent the fixed needle guard from interfering with other parts during movement. Therefore, the applicant proposed further improvements on this basis and designed a needle guard device to meet the needs of the existing market. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the existing defects and provide a needle guard plate device with a simple overall structure.

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0005] A needle guard plate device, characterized in that: it includes a corner seat, on which is a needle guard plate assembly, the needle guard plate assembly includes a needle guard plate seat bracket installed on the corner seat, one end of the needle guard plate seat bracket is hinged to the first needle guard plate seat, the other end of the first needle guard plate seat is mounted on the second needle guard plate seat, and the other end of the second needle guard plate seat is mounted on the needle guard plate; the first needle guard plate seat is provided with a cylinder, when the cylinder does not supply air, the needle guard plate is tightly attached to the corner seat, when work is not needed, the cylinder starts to supply air, the cylinder piston starts to advance, the first needle guard plate seat is tilted up, the needle guard plate is not tightly attached to the corner seat, and the cycle is repeated in sequence.

[0006] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0007] When the utility model needs to work, the cylinder part of the needle guard plate seat is not supplied with air, and the needle guard plate is tightly attached to the corner seat. When it does not need to work, the cylinder part of the needle guard plate seat starts to supply air, the cylinder piston starts to move in, the needle guard plate seat is tilted up, and the needle guard plate is not tightly attached to the corner seat, and the cycle is in sequence, which plays the effect of preventing the fixed needle guard plate from interfering with other parts during movement.
