DETAILED DESCRIPTION

[0022] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0023] As described in the background technology, the installation of the embroidery frame requires the operator to manually rotate the two sets of fixing rods, so that the two sets of fixing rods drive the two sets of fixing plates to approach each other, ensuring that the two sets of fixing pads can be in close contact with the embroidery frame. This not only increases the operator's operating steps, but also makes it impossible to rotate and clamp the embroidery frame in one time, affecting the efficiency of subsequent embroidery processing. For this reason, this embodiment provides an embroidery positioning device for an embroidery machine.

[0024] See also Figures 1 to 4 This embodiment proposes an embroidery positioning device for an embroidery machine, including a support plate 1, a bottom plate 7 is arranged below the support plate 1, the support plate 1 is slidably connected to the bottom plate 7, two second fixed plates 8 are fixedly connected to the upper surface of the bottom plate 7, the bottom plate 7 supports the support plate 1, and the support plate 1 can slide along the upper surface of the bottom plate 7, and the bottom plate 7 fixedly supports the second fixed plates 8.

[0025] The inner wall of the support plate 1 is threadedly connected with a second threaded rod 9, and the two second fixed plates 8 are rotatably connected to the second threaded rod 9. A handle 10 is installed on the outer surface of the second threaded rod 9. Rotating the handle 10 can drive the second threaded rod 9 to rotate, thereby driving the support plate 1 to move, and the second threaded rod 9 is supported in a limited position by the two second fixed plates 8.

[0026] Two symmetrical scale lines 11 are arranged on the upper surface of the bottom plate 7. The scale lines 11 can be used to measure the position of the embroidery frame when the embroidery frame is placed.

[0027] A positioning mechanism 2 is arranged above the support plate 1, and the positioning mechanism 2 includes a servo motor 201 and two limit plates 205. The servo motor 201 is fixedly connected to the support plate 1, and the two output shaft ends of the servo motor 201 are fixedly connected to the first threaded rod 202, and the outer surfaces of the two first threaded rods 202 are threadedly connected to the support blocks 203, and the two support blocks 203 are slidably connected to the support plate 1.

[0028] The support plate 1 provides fixed support for the servo motor 201. After the servo motor 201 is started, it can drive the two first threaded rods 202 to rotate synchronously in forward and reverse directions. After the two first threaded rods 202 rotate, they can drive the two support blocks 203 to slide synchronously along the upper surface of the support plate 1, and the two support blocks 203 move closer to or away from each other.

[0029] Two first fixing plates 3 are fixedly connected to the upper surface of the support plate 1. The two first fixing plates 3 are rotatably connected to the two first threaded rods 202 respectively. The first fixing plates 3 can provide auxiliary support for the support block 203 to improve the stability of the support block 203 when rotating.

[0030] Two guide rods 4 are arranged above the support plate 1, and the two guide rods 4 are fixedly connected to the two first fixed plates 3 respectively, and the two guide rods 4 are slidingly connected to the two first threaded rods 202 respectively. The guide rods 4 can guide the movement of the support block 203, making it more stable during the left and right movement.

[0031] The outer surfaces of the two first threaded rods 202 are threadedly connected with sliders 5, and the two sliders 5 are slidably connected to the support plate 1. The inner walls of the two sliders 5 are hinged with articulated rods 6 through pins, and the two articulated rods 6 are respectively hinged to the two support blocks 203 through pins.

[0032] After the first threaded rod 202 rotates, it can drive the slider 5 to slide along the upper surface of the support plate 1, and the slider 5 and the support block 203 on the same side have the same moving direction and speed. After the slider 5 moves, it can drive the hinged rod 6 to move, and the hinged rod 6 moves with the support block 203, thereby achieving auxiliary support for the support block 203, making it more stable when in use.

[0033] The inner walls of the two support blocks 203 are slidably connected to two sliding rods 204, and the four sliding rods 204 are respectively fixedly connected to the two limit plates 205. The outer surface of each sliding rod 204 is sleeved with a return spring 206, and the four return springs 206 are respectively fixedly connected to the two support blocks 203, and the four return springs 206 are respectively fixedly connected to the two limit plates 205.

[0034] In the initial state, the spacing value between the two support blocks 203 is the maximum value. After the support block 203 moves, the limit plate 205 can be driven to move by the return spring 206, and the limit plate 205 drives the slide bar 204 to move. At the same time, the slide bar 204 can slide inside the hole reserved on the support block 203.

[0035] The support block 203 is in a T-shape, which can conveniently support the bottom of the embroidery frame when the embroidery frame of the embroidery machine is clamped and fixed, avoiding the embroidery frame being in a suspended state, resulting in unstable clamping and fixing. A sponge pad is provided on the limiting plate 205 to avoid damage caused by excessive clamping force during the clamping and fixing of the embroidery frame.

[0036] One end of each slide bar 204 away from the limiting plate 205 is fixedly connected to the limiting block 12 , and the limiting block 12 can limit the slide bar 204 to prevent the slide bar 204 from slipping off the inner wall of the support block 203 .

[0037] Two mounting blocks 13 are fixedly connected to one side and the other side of the base plate 7. The inner wall of each mounting block 13 is provided with an internal thread. The mounting block 13 can install and fix the base plate 7, thereby realizing the limited fixation of the embroidery positioning device for the embroidery machine. The holes provided on the mounting block 13 can be waist-shaped holes, which is convenient for fine adjustment of the installation position of the embroidery positioning device for the embroidery machine.

[0038] Working principle: when using the embroidery positioning device for the embroidery machine to fix the embroidery frame on the embroidery machine, the embroidery frame is placed between the two support blocks 203, and then the servo motor 201 is controlled to start. After the servo motor 201 is started, the two support blocks 203 can be driven to rotate synchronously. After the two first threaded rods 202 rotate, the two support blocks 203 can be driven to slide synchronously along the upper surface of the support plate 1, and the two support blocks 203 approach each other. The two support blocks 203 drive the two limit plates 205 to approach each other through the reset springs 206 connected thereto, until the two limit plates 205 are respectively fitted with the left and right sides of the embroidery frame to achieve preliminary fixation of the embroidery frame. After that, the two limit plates 205 continue to approach, driving the slide bar 204 to slide in the reserved hole on the support block 203. The embroidery frame is moved and the return spring 206 is compressed to make it deform elastically. Under the return action of the return spring 206, the clamping force on the embroidery frame is buffered and offset to avoid damage to the embroidery frame. At this time, the bottom surface of the embroidery frame is in contact with the outer surface of the supporting block 203 to avoid the embroidery frame being in a suspended state until the embroidery frame is stably fixed to ensure stability during embroidery. When fixing the embroidery frame on the embroidery machine, the utility model can use two limit plates 205 that can be close to or away from each other to clamp and fix embroidery frames of different sizes, thereby avoiding the problem of the embroidery frame loosening due to force during embroidery, thereby improving the stability of the embroidery frame, and at the same time reducing the operating steps of the operator, improving the practicability of the embroidery positioning device for the embroidery machine when using it, thereby improving the efficiency of embroidery processing of the embroidery machine.
