[0010] Further, the spiral groove can be single-headed or multi-headed and matched with the guide shaft.

[0011] Further, the mounting frame for mounting the driving motor and the driving wheel and the connecting plate for the sliding of the lifting block are further included.

[0012] Further, the mounting frame and the connecting plate are separately arranged or connected.

[0013] Further, the sliding rail assembly comprises a sliding groove arranged on the lifting block and a sliding block arranged on the connecting plate.

[0014] Compared with the prior art, the embroidery machine lifting driving mechanism has the advantages that:

[0015] The utility model provides a kind of embroidery machine lifting driving mechanism, including lifting block and drive wheel, be equipped with spiral groove on drive wheel, be equipped with a plurality of sequentially arranged guide shaft matched with spiral groove on lifting block, guide shaft is inserted into spiral groove, spiral groove rotates continuously and is matched with guide shaft, guide shaft enters from the guide entrance of spiral groove, and export is guided, realize lifting action, the freedom of guide shaft is limited, self-locking ability is better relative to screw rod, it can realize the self-locking of arbitrary position, the position of lifting is more accurate, positioning difference is not prone to appear, simultaneously, it is not necessary to provide redundant driving force by motor, reduce driving current, reduce motor heating, not only save resources, but also prolong the service life of motor.

[0016] Figure 1 It is whole structure schematic diagram of the utility model;

[0017] Figure 2 、 3 It is partial structure schematic diagram of different angle;

[0018] Among them, lifting block 1, drive wheel 2, drive motor 3, guide shaft 4, spiral groove 5, embroidery mechanism 6, mounting frame 7, sliding rail assembly 8, sliding groove 801, sliding block 802, connecting plate 9. DETAILED DESCRIPTION

[0019] The utility model will be further described in connection with specific embodiment.

[0020] Reference Figure 1 、 2 , 3, a kind of embroidery machine lifting driving mechanism, including lifting block 1, drive lifting block 1 lifting drive wheel 2 and corresponding drive motor 3, the lifting block is sequentially arranged with the protruding guide shaft 4 outside, the drive wheel is equipped with the spiral groove 5 matched with guide shaft 4 outside, spiral groove 5 is equipped with guide entrance and export matched with guide shaft 4.

[0021] Guide shaft 4 is clamped in spiral groove 5, by the rotation of drive wheel 2, spiral groove 5 continuously cooperates with guide shaft 4, so that guide shaft is guided into spiral groove 5 from guide entrance, and export is guided, to realize the lifting of lifting block 1.The lifting block 1 is connected on the embroidery mechanism 6 needed to be lifted by embroidery machine, and lifting block 1 lifting can drive embroidery mechanism 6 to move up and down.

[0022] Still include mounting frame 7 for installing drive motor 3 and drive wheel 2, connecting plate 9 for lifting block 1 sliding, the connecting plate 9 is equipped with sliding rail assembly 8 between lifting block 1.

[0023] The mounting frame 7 and connecting plate 9 are separately provided or connected to be provided.The direct connection can be connected indirectly.

[0024] The sliding rail assembly 8 comprises a sliding groove 801 arranged on the lifting block 1 and a sliding block 802 arranged on the mounting frame 7, of course, the sliding groove 801 can be arranged on the mounting frame 7, and the sliding block 802 matched with the sliding groove 801 is arranged on the lifting block 1, so that the lifting block 1 can slide up and down relative to the mounting frame 7.

[0025] Since the freedom of the guide shaft 4 is limited, the relative positioning of the guide shaft 4 in the helical groove 5 can be realized, the self-locking ability is better than that of a screw rod or a lead screw, the positioning is more accurate, and the positioning error is not prone to occur. Meanwhile, the self-locking at any position is realized, the driving current consumed by the driving motor 3 is not large, the heating of the motor is reduced, and the service life of the motor is prolonged.

[0026] The lifting block 1 can be a lifting column or a lifting plate. The embroidery mechanism can be a gold sheet embroidery mechanism, a bead embroidery mechanism or a string embroidery mechanism.

[0027] In order to reduce the abrasion between the helical groove and the guide shaft 3, bearings can be arranged between the guide shaft and the helical groove, the bearings can be directly arranged outside the guide shaft 3, the friction between the guide shaft and the helical groove is reduced, and driving is smoother. The bearings can adopt the prior art.

[0028] The helical groove can be single-headed or multi-headed and matched with the guide shaft, the driving speeds of the single-headed or multi-headed helical groove are different when rotating, and the driving speed can be selected according to the requirement, so that high-efficiency driving is ensured.

[0029] The above only describes optional embodiments of the utility model, and does not limit the patent range of the utility model, and any equivalent structural transformation made under the inventive concept of the utility model, or direct / indirect application in other related technical fields is included in the patent protection range of the utility model.
