Description

Technical Field

[0001] The utility model relates to the technical field of clothing processing, in particular to an automatic thread trimming and edge locking machine. Background Art

[0002] At present, polyester and other processing materials widely used in the field of garment processing are generally synthetic fibers. After cutting, the threads at the edges of the fabrics often spread out, causing damage to the clothes and reducing product quality. Therefore, in the field of garment processing, in order to prevent the threads from spreading out, the processing of the edges of the cut pieces is essential, which directly affects the durability and appearance of the garments.

[0003] Existing automatic thread trimming and edge locking machines, such as the automatic thread trimming and edge locking machine disclosed in Chinese patent application CN204237985U, record that: when the edge locking process is completed, the suction pipe sucks air under the action of the suction fan, thereby straightening the edge locking line. At the same time, the infrared sensor of the workbench senses that the edge locking process is completed and generates a related signal, and transmits this signal to the controller. The controller processes this signal and sends a command to control the driver to work, thereby driving the knife body to move and complete the thread trimming process.

[0004] During use of the above-mentioned automatic thread trimming and edge locking machine, the lines on the equipment are sucked into a straight state through the suction fan along the suction duct, and one end of the sucked line is still in an active state. When the knife body is driven to cut the line for edge locking, the downward movement of the knife will drive the active line to move, resulting in inaccurate position of the thread head during cutting, affecting the edge locking effect, and when the knife is cutting the line, if the knife is not sharp enough or the cutting speed is too fast, the line will be pulled downward, which will cause the incision position to shift, resulting in inaccurate or uneven incision, affecting the dimensional accuracy and aesthetics of the product.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model is further described below in conjunction with embodiments.

[0025] Example 1

[0026] Reference Figure 1-3 , which is the first embodiment of the utility model, provides an automatic thread trimming and edge locking machine, including a suction fan 100, on which a straightening and cutting mechanism 200 is installed, and the straightening and cutting mechanism 200 includes a clamping seat 201 arranged on one side of the suction fan 100, and a spring piece 202 is arranged in the clamping seat 201, and a clamping slide 203 is slidably connected to the clamping seat 201, and a clamping pressure plate 204 is arranged above the clamping slide 203, and a threaded sleeve 205 is fixedly connected to one side of the clamping pressure plate 204, and a screw 206 is screwed in the threaded sleeve 205. By rotating the screw 206, the threaded sleeve 205 drives the clamping pressure plate 204 to move downward, squeeze the clamping slide 203 to slide into the clamping seat 201, and clamp the line between the clamping slide 203 and the clamping pressure plate 204.

[0027] The end of the screw rod 206 away from the threaded sleeve 205 is sleeved with a driving motor 207 , and the side of the clamping seat 201 away from the driving motor 207 is fixedly connected with a sliding rod 208 , which drives the screw rod 206 to rotate through the output end of the driving motor 207 .

[0028] A slider 209 is slidably connected to the slide bar 208, and the slider 209 is fixedly connected to the side of the clamping plate 204 away from the threaded sleeve 205. A suction pipe 210 is fixedly connected to one side of the suction fan 100. By turning on the suction fan 100 to suck air along the suction pipe 210, the lines on the equipment are sucked into a straight state. By controlling the lifting and lowering of the clamping plate 204, the slider 209 on one side of the clamping plate 204 will slide along the slide bar 208, playing a limiting role, preventing the clamping plate 204 from rotating with the threaded sleeve 205.

[0029] During use, the suction fan 100 is turned on to suck air along the suction pipe 210 to suck the lines on the equipment into a straight state, and the output end of the driving motor 207 drives the screw 206 to rotate, so that the threaded sleeve 205 drives the clamping plate 204 to move downward and squeeze the clamping slide 203 to slide into the clamping seat 201, and the lines between the clamping slide 203 and the clamping plate 204 are clamped. After the lines are straightened and clamped, it can be ensured that the lines are in an ideal state. After cutting, the lock edge can be made smoother and neater, thereby improving product quality.

[0030] Example 2

[0031] Reference Figure 1-4, which is the second embodiment of the utility model, provides an automatic thread trimming and overlocking machine, including a clamping seat 201, a side of which is away from the suction pipe 210 and is connected to a wire-releasing plate 211, a support frame 212 is fixedly connected to one side of the wire-releasing plate 211, a cylinder 213 is fixedly connected to the support frame 212, and a motor bracket 214 is fixedly connected to the output end of the cylinder 213, and the motor bracket 214 is pushed downward toward the line on the wire-releasing plate 211 through the output end of the cylinder 213.

[0032] The motor bracket 214 is connected with an adjusting motor 215 , and the output end of the adjusting motor 215 is sleeved with a rotating disk 216 , so that the rotating disk 216 is driven to rotate forward and reversely through the output end of the adjusting motor 215 .

[0033] The two ends of the turntable 216 are rotatably connected with pull rods 217, and the end of the pull rod 217 away from the turntable 216 is rotatably connected to the tool 218. The wire release plate 211 is connected with a cutting slide 219, and the tool 218 moves downward toward the straightened lines. Through the forward and reverse rotation of the turntable 216, the pull rod 217 on one side is pulled upward, and the pull rod 217 on the other side is pushed downward, so that the tool 218 rotates along the cutting slide 219 to cut the line. The sliding cut of the tool 218 can reduce the tension on the line during the cutting process, avoid thread breakage or line deformation, and improve the overall aesthetics of the product.

[0034] During use, the cylinder 213 pushes the tool 218 to move downward toward the straightened line. Through the forward and reverse rotation of the turntable 216, the pull rod 217 on one side is pulled upward, and the pull rod 217 on the other side is pushed downward, so that the tool 218 rotates along the cutting slide column 219 to cut the line. The sliding cut of the tool 218 can reduce the tension on the line during the cutting process, avoid thread breakage or line deformation, and improve the overall aesthetics of the product.
