Abstract

The utility model discloses a needle board used in the auto-thread-shearing chain type embroidery machine, which can prevent components of thread clamping brackets from being deadlocked between supporting arms of a guide plate and a stationary knife. The needle board comprises a needle board body, wherein, needle holes and fixing and installing holes are arranged in the needle board body, and positioning grooves are arranged on the bottom of the needle board body. The needle board is mainly used in the multi-needle auto-thread-shearing chain type embroidery machine, thereby ensuring that the embroidery machine changes color more reliably.

Description

The needle plate that is used for automatic shearing chain type embroidery machine

Technical field

The utility model relates to the needle plate that is used for automatic shearing chain type embroidery machine.

Background technology

As shown in Figure 1, be used for the needle plate of automatic shearing chain type embroidery machine, its structure comprises: upper surface and bottom surface are parallel to each other and smooth needle plate body 1, are provided with pin hole 11 and fixed installation hole 12 in the needle plate body 1.As shown in Figure 2, guide plate 2, stationary knife 3 and needle plate shown in Figure 1 are installed on the holder 4 successively, the bottom of holder 4 is provided with stretches out boss 41, usually be provided with the clamp bracket component 5 that is used for automatic shearing between boss 41 and the needle plate stretching out, clamp bracket component 5 is provided with clamp reed 51 and cover plate 52, clamp reed 51 are resisted against on the cover plate 52, and vertical range H is about 0.3 millimeter between the support arm (remaining basically stable in the bottom surface of the support arm of guide plate 2 and stationary knife 3) of cover plate 52 and guide plate 2 and stationary knife 3---referring to shown in Figure 3.In the use of reality, cover plate 52 on the clamp bracket component 5 is owing to constantly be subjected to the effect of clamp reed 51 parts such as grade, time one, long cover plate 52 will deform, the upper surface of its distortion contacts with the bottom surface of guide plate 2 or stationary knife 3 supporting arms, produce frictional resistance when making colour changing, increase the weight of the load (because the restriction of installing space, original motor can not strengthen) of colour changing motor.Like this, the supporting arm stuck phenomenon of clamp bracket component 5 and guide plate 2 and stationary knife 3 will occur, cause normally colour changing of embroidery machine.

The utility model content

Technical problem to be solved in the utility model is: a kind of needle plate that is used for automatic shearing chain type embroidery machine that prevents that the clamp bracket component from contacting with the supporting arm of guide plate and stationary knife is provided.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is: be used for the needle plate of automatic shearing chain type embroidery machine, comprise: the needle plate body, be provided with pin hole and fixed installation hole in the needle plate body, and the bottom surface of described needle plate body is provided with the arrangement groove.

Pin hole and fixed installation hole are avoided in the position of above-mentioned arrangement groove.

The beneficial effects of the utility model are: the utility model is by offering the arrangement groove on the bottom surface of needle plate body, and the top of the supporting arm of guide plate and stationary knife is placed described arrangement groove, thereby increased the distance between the supporting arm of clamp bracket component and guide plate and stationary knife, even if some distortion of clamp bracket component, can not contact yet, so just guaranteed normally carrying out of embroidery machine colour changing with the supporting arm of guide plate and stationary knife.

The specific embodiment

Below in conjunction with accompanying drawing, describe specific embodiments of the present utility model in detail.

As shown in Figure 4, the needle plate that is used for automatic shearing chain type embroidery machine described in the utility model, comprise: needle plate body 1, be provided with pin hole 11 and fixed installation hole 12 in the needle plate body 1, the bottom surface of described needle plate body 1 is provided with settles groove 13, settle the degree of depth of groove 13 to be about 1.5 millimeters, can not influence the intensity of needle plate body 1, settle the position of groove 13 to avoid pin hole 11 and fixed installation hole 12.

When practical application, as Fig. 5, shown in Figure 7, guide plate 2, stationary knife 3 and needle plate shown in Figure 4 are installed on the holder 4 successively, the bottom of holder 4 is provided with stretches out boss 41, usually be provided with the clamp bracket component 5 that is used for automatic shearing between boss 41 and the needle plate stretching out, clamp bracket component 5 is provided with clamp reed 51 and cover plate 52, clamp reed 51 is resisted against on the cover plate 52, because the top of the supporting arm of guide plate 2 and stationary knife 3 places the arrangement groove 13 of needle plate body 1, make that vertical range H has reached 1.8 millimeter between the support arm of cover plate 52 and guide plate 2 and stationary knife 3---referring to shown in Figure 6, the spacing of this clamp bracket component that has increased 5 and the supporting arm of guide plate 2 and stationary knife 3, for Free up Memory has been reserved in the distortion of cover plate 52, can not contact with the supporting arm of guide plate 2 and stationary knife 3.Like this, just guaranteed normally carrying out of embroidery machine colour changing.

Claims

1. be used for the needle plate of automatic shearing chain type embroidery machine, comprise: the needle plate body, be provided with pin hole and fixed installation hole in the needle plate body, it is characterized in that: the bottom surface of described needle plate body is provided with the arrangement groove.

2. needle plate as claimed in claim 1 is characterized in that: pin hole and fixed installation hole are avoided in the position of described arrangement groove.
