DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1 , Figure 2As shown, a pre-positioning device for embroidery fabric production includes a workbench 1 and an embroidery head 2, a leather paper layer 3 is arranged on the workbench 1, and a positioning device is arranged on the embroidery head 2, the positioning device includes a bracket 4 slidably connected to the embroidery head 2 and a driving mechanism for driving the bracket 4 to slide up and down, and pressing plates 5 are arranged on both sides of the bracket 4, and the two pressing plates 5 are respectively arranged on both sides of the embroidery head 2. Before embroidering the cloth, the cloth can be first spread on the leather paper layer 3 to align it with the embroidery head 2, and then the bracket 4 is driven to slide down by the driving mechanism, so that the pressing plate 5 slides down accordingly until the pressing plate 5 contacts the cloth and presses the cloth against the leather paper layer 3, and then the embroidery is performed through the embroidery head 2. Since the cloth is pre-positioned by the positioning device before embroidery, the stability of the cloth during embroidery is guaranteed, thereby ensuring the quality of embroidery, and positioning by the positioning device is efficient, convenient to operate, and saves time and effort.

[0021] See also Figure 1-4 As shown, an extension mechanism connected to the pressing plate 5 is provided on both sides of the bracket 4, and the extension mechanism is used to drive the pressing plate 5 to move closer to or away from the bracket 4. When positioning the cloth, the pressing plate 5 can be driven closer to or away from the bracket 4 by the extension mechanism, so as to adjust the distance between the two pressing plates 5, and then it can be suitable for pressing cloths of different lengths, thereby improving the applicability of the positioning device. The extension mechanism includes a telescopic arm and a power component for driving the telescopic arm to expand or contract. The telescopic arm can be driven to expand or contract by the drive of the power component, thereby driving the pressing plate 5 to move closer to or away from the bracket 4, and the operation is relatively convenient and simple. The telescopic arm includes two sets of mutually parallel crossing arms, and the crossing arm includes a first support rod 6 and a second support rod 7 hinged to each other, and one end of the first support rod 6 is hinged to the pressing plate 5, and the other end is slidably connected to On the side wall of the bracket 4, one end of the second support rod 7 is slidably connected to the pressure plate 5, and the other end is hinged on the side wall of the bracket 4. A connecting rod 8 is arranged between adjacent first support rods 6. The power assembly includes a first cylinder 9 fixed on the side wall of the bracket 4, and the first push rod 10 of the first cylinder 9 is connected to the connecting rod 8. When it is necessary to drive the telescopic arm to expand, the first cylinder 9 can be started and the first push rod 10 can be driven to extend, so that the first support rod 6 can be driven to slide in the direction away from the second support rod 7 through the connecting rod 8, so that the cross arm can be expanded, thereby driving the telescopic arm to expand. When it is necessary to drive the telescopic arm to fold, the first cylinder 9 can be started and the first push rod 10 can be driven to shrink, so that the first support rod 6 can be driven to slide in the direction close to the second support rod 7 through the connecting rod 8, so that the cross arm can be contracted, thereby driving the telescopic arm to shrink. The efficiency is high and the operation is convenient.

[0022] See also Figure 4As shown, an anti-slip sleeve 11 is provided at one end of the pressing plate 5 facing the leather paper layer 3, and a plurality of anti-slip protrusions 12 are provided on the anti-slip sleeve 11, thereby increasing the friction coefficient of the surface of the anti-slip sleeve 11, so that the anti-slip sleeve 11 has good anti-slip properties, and when the cloth is pressed by the pressing plate 5, the anti-slip sleeve 11 will contact with the surface of the cloth, so that the cloth is not easy to slip after being pressed, thereby further improving the stability of the cloth, wherein the anti-slip sleeve 11 and the anti-slip protrusions 12 are both made of silicone material, which is soft and has good toughness, so when the anti-slip sleeve 11 contacts with the cloth, it is not easy to damage the surface of the cloth, thereby effectively protecting the cloth.

[0023] See also Figure 2 As shown, the driving mechanism includes a second cylinder 13 fixed on the side wall of the embroidery head 2, and a connecting seat 27 is connected to the second push rod 14 of the second cylinder 13, and the connecting seat 27 is fixedly connected to the bracket 4. By starting the second cylinder 13, the second push rod 14 is driven to extend or contract, and the bracket 4 can be driven to slide up and down through the connecting seat 27, thereby driving the pressing plate 5 to move accordingly, so as to achieve the compression or release of the cloth, which is convenient to operate and has high efficiency. A slide groove 15 is opened in the vertical direction on the side wall of the embroidery head 2, and a slider 16 slidably connected to the inside of the slide groove 15 is provided on the bracket 4. When the bracket 4 slides up and down, the slider 16 will slide along the slide groove 15 accordingly, and the sliding direction of the bracket 4 can be limited by the fiber of the slider 16 through the slide groove 15, so that the sliding of the bracket 4 is more stable and smooth.

[0024] See also Figure 1 , Figure 5As shown, an adjusting device for driving the embroidery head 2 to move along the warp and weft directions is provided on the workbench 1. The embroidery head 2 can be driven to move by the driving of the adjusting device, so that embroidery can be performed at any position of the workbench 1, thereby ensuring the embroidery effect. The adjusting device includes warp slide rails 17 arranged on both sides of the workbench 1, support beams 18 are slidably connected between the warp slide rails 17, and weft slide rails 19 are arranged on the support beams 18. The embroidery head 2 is provided with a sliding seat 20 slidably connected to the weft slide rails 19, and a first motor 21 is provided on the warp slide rail 17. A first screw rod 22 is connected to the output end of the first motor 21, and a first nut seat 23 is threadedly connected to the first screw rod 22. The first nut seat 23 is connected to the support beam 18. A second motor 24 is provided on the support beam 18, and a second screw rod 25 is connected to the output end of the second motor 24, and a second nut seat 26 is threadedly connected to the second screw rod 25, and the second nut seat 26 is connected to the sliding seat 20. By starting the first motor 21, the first screw rod 22 is driven to rotate, and the first nut seat 23 can be driven to move along the length direction of the first screw rod 22, thereby driving the support beam 18 to slide along the length direction of the warp slide rail 17, and then driving the embroidery head 2 to move along the warp direction. By starting the second motor 24, the second screw rod 25 is driven to rotate, and the second nut seat 26 can be driven to move along the length direction of the second screw rod 25, thereby driving the sliding seat 20 to slide along the length direction of the weft slide rail 19, and then driving the embroidery head 2 to move along the weft direction, which has high efficiency.
