Description

Technical Field

[0001] This utility model relates to the field of embroidered fabric trimming, specifically a thread suction and trimming device for embroidered fabric. Background Technology

[0002] After the fabric is embroidered, due to differences in patterns and embroidery techniques, there will be connected threads of varying lengths and quantities. These threads are trimmed manually or by large traditional shearing machines. Shearing machines can easily pick up, cut, and collect the threads from the fabric, reducing labor intensity, improving work efficiency, and reducing environmental pollution.

[0003] According to the published patent 202321702182.8, a thread suction and cutting device for embroidery fabric, it includes a base plate, two vertical plates and four support rods fixedly mounted on the top of the base plate, and a winding roller rotatably connected between each pair of corresponding vertical plates via a rotating shaft. A first motor is fixedly mounted on the front of one of the vertical plates, and a top plate is fixedly mounted on one end of each of the four support rods. Two pressing components are mounted on the bottom end of the top plate. The beneficial effects of this utility model are: the telescopic ends of the four electric push rods extend and push the two supports to move, and the two supports drive the two filter cylinders to move through the four baffles. The two filter cylinders can push the embroidery fabric and realize the reversal of the embroidery fabric. Compared with the prior art, the embroidery fabric does not need to be attached to several guide rollers that are far apart from each other when feeding, which facilitates manual feeding.

[0004] However, in traditional embroidery thread-cutting devices, thread ends generated during embroidery can penetrate small holes in the outer wall of the filter cylinder and enter its interior. Once inside, these thread ends are cut by a specialized scraper. Subsequently, the fan blades within the device begin to rotate to generate suction. However, the filter cylinder is relatively long, and the fan blades are only installed at one end. The airflow generated by the fan blades is difficult to evenly cover all areas inside the filter cylinder, especially those far from the blades, making it difficult to extract the thread ends. Therefore, a new technical solution is needed to address this issue. Utility Model Content

Once these thread ends are inside, they are cut by a special scraper. Subsequently, the fan blades in the device begin to rotate to generate suction. However, the filter cylinder is relatively long, and the fan blades are only installed at one end of the filter cylinder. As a result, the airflow generated by the fan blades is difficult to evenly cover all areas inside the filter cylinder, especially those areas far from the fan blades, leading to the technical problem of thread ends being difficult to be sucked up.

[0023] Further, referring to Figure 1 The collecting box 203 is installed at the rear end of the second fixed plate body 102, and a filter screen body 204 is installed at the rear end of the collecting box 203.

[0024] It is worth noting that, referring to Figure 2The first pipe body 207 is located in the collecting box 203, and a connecting pipeline 205 is communicated with the front end of the first pipe body 207. A negative pressure fan 206 is communicated with the side of the connecting pipeline 205. A screen is arranged between the position where the negative pressure fan 206 is communicated with the connecting pipeline 205.

[0025] It is worth noting that, referring to Figure 2 The front end of the connecting pipeline 205 penetrates through the second fixed plate body 102 and is rotatably communicated with a rotary joint 208. The front end of the rotary joint 208 is fixedly communicated with a second pipe body 212. The second pipe body 212 extends into the rotary cylinder 201, and one end thereof located in the rotary cylinder 201 is in a sealed structure. A plurality of line shearing cutter bodies 213 are mounted on the surface of the second pipe body 212.

[0026] It is worth noting that, referring to Figure 3 A negative pressure cavity 214 is arranged in the line shearing cutter body 213. The negative pressure cavity 214 extends to the cutter head of the line shearing cutter body 213 in a bifurcated manner. The negative pressure cavity 214 is communicated with the second pipe body 212.

[0027] It is worth noting that, referring to Figure 2 The rotary joint 208 penetrates through a first gear 209. The first gear 209 is fixedly connected with the penetration position of the rotary joint 208. The bottom of the first gear 209 is engaged with a second gear 211. One end of the second gear 211 is connected with a second motor 210. The second motor 210 is mounted on the surface of the second fixed plate body 102.

[0028] In use, the embroidery cloth is first threaded into the top of the rotating cylinder 201 from one side, ensuring that one side of the embroidery cloth is in contact with the outer surface of the rotating cylinder 201, and then the embroidery cloth is threaded out of the bottom of the rotating cylinder 201 from the other side, so that the other side of the embroidery cloth is in contact with the outer surface of the other rotating cylinder 201. A plurality of holes 202 are provided on the surface of the rotating cylinder 201. When the embroidery cloth is in contact with the rotating cylinder 201 and moves, the thread will pass through the holes 202 into the interior of the rotating cylinder 201. When it is necessary to move the embroidery cloth, the first motor 2 is turned on, and the motor drives the rotating cylinder 201 to start rotating. Since the embroidery cloth is in contact with the outer surface of the rotating cylinder 201, the rotation of the rotating cylinder 201 will drive the embroidery cloth to move, achieving the conveying function. When it is necessary to perform the thread cutting operation, the second motor 210 is first turned on. After the second motor 210 is started, it will drive the second gear 211 connected thereto to rotate. The second gear 211 is in meshing engagement with the first gear 209, so the rotation of the second gear 211 will drive the first gear 209 to rotate. The first gear 209 is connected to the rotating joint 208, so the rotation of the first gear 209 will further drive the rotating joint 208 to rotate. The rotating joint 208 is connected to the second pipe body 212 and the thread cutting knife body 213, so the rotation of the rotating joint 208 will drive the second pipe body 212 and the thread cutting knife body 213 to rotate together. When the thread cutting knife body 213 rotates to contact the thread extending into the rotating cylinder 201, the sharp edge of the blade will cut the thread. In the process of cutting the thread, the negative pressure fan 206 can be turned on at the same time. The negative pressure fan 206 (specific model ZF-120) will extract the air in the connecting pipeline 205 after being started, thereby reducing the air pressure in the connecting pipeline 205 and forming negative pressure. Since the first pipe body 207 and the second pipe body 212 are respectively connected to the two ends of the connecting pipeline 205, air will be sucked into the negative pressure cavity 214 opening communicated with the second pipe body 212 to supplement the air extracted by the negative pressure fan 206. Thus, the negative pressure acts on the negative pressure cavity 214 in the pipe body and the thread cutting knife body 213. Under the action of the negative pressure, the thread cut by the thread cutting knife body 213 will be directly sucked into the negative pressure cavity 214 and the pipe body. The pipe body is connected to the collection box 203, so the sucked thread will eventually be discharged into the collection box 203, achieving effective collection of the thread.
