Embodiment 1

[0032] like Figure 1 to Figure 4 As shown, the device with the function of auxiliary presser foot and presser foot protection includes a protective piece 1, a fixing seat 7, and an elastic buffer. The protective piece 1 is provided with a through hole 111 for the needle bar 101 and the presser foot 102 to pass through. The protective piece 1 is movably connected with the fixed seat 7, and the elastic buffer is arranged between the protective piece 1 and the fixed seat 7. When the protective piece 1 is impacted, the elastic buffer absorbs and buffers the impact force.

[0033] Moreover, the bottom of the protective member 1 has a cloth pressing surface, which can not only directly resist the impact of hard objects, but also play an auxiliary cloth pressing effect. In addition, the protective member 1 has a protective cover in which the needle bar 101 and the presser foot 102 can be covered.

[0034] Therefore, when improper operation occurs, the protective part 1 will rebound...

Embodiment approach

[0037] As an implementation manner, the protective member 1 includes a bowl-shaped portion 11 arranged horizontally, and the through hole 111 is arranged at the bottom of the bowl. The bowl bottom of the bowl-shaped part is used as the cloth pressing surface and the via hole 111 runs through the cloth pressing surface up and down. The side wall of the bowl-shaped portion 11 serves as a protective cover to protect the bottom of the needle bar 101 and the presser foot 102, so as to protect the presser foot and the needle bar from being damaged. Because the guard has the effect of auxiliary cloth pressing simultaneously, the cloth pressing surface at the bottom of the bowl-shaped portion can be set larger, for example twice or more than the common presser foot.

[0038] Specifically, the bowl-shaped portion is connected with an inclined section 12, and the inclined section 12 is connected with a horizontal section 13, and the horizontal section 13 is partly fixed to the bottom su...

Embodiment 2

[0044] refer to image 3 and Figure 4 As shown, the embroidery machine includes a machine head, and the machine head includes a machine head housing 200 and a needle bar frame 100. The device with auxiliary presser feet and presser foot protection functions is a part of the machine head, wherein the needle bar frame 100 A row of needle bars 101 and corresponding presser feet 102 are provided. A lifting shaft 8 and a lifter 9 are arranged on the machine head housing, and the lifting shaft 8 is arranged in a vertical guide hole.

Abstract

The invention discloses a device with functions of assisting a presser foot and protecting the presser foot and an embroidery machine. The device comprises a protection piece, a fixed base and an elastic buffering piece, the protection piece is provided with a via hole for a needle bar and the presser foot to pass through, the protection piece is movably connected with the fixed base, the elasticbuffering piece is arranged between the protection piece and the fixed base, and when the protection piece is under impact, the elastic buffering piece absorbs and buffers impact force. The device isprovided with the protection piece and the elastic buffering piece, when misoperation occurs, the protection piece can be rebounded through the elastic buffering piece when impacted by a hard object,the situation that the presser foot and the needle bar are directly under impact is avoided, thus the presser foot and the needle bar are protected against damage, and the situation that since the pressure foot and the needle bar are not protected, the maintenance rate is too high is avoided. The protection piece has the function of assisting in cloth pressing, in some working environments where fabric is fluffy, larger cloth pressing areas are needed, and then the protection piece achieves the effect of assisting in cloth pressing.

Description

technical field [0001] The invention relates to the technical field of embroidery machines. Background technique [0002] At present, the presser foot of the embroidery machine is not equipped with a protective structure, so when the presser foot hits a hard object during improper operation, the presser foot and the needle bar will be damaged, resulting in a high maintenance rate.
