Description

Technical Field

[0001] The utility model belongs to the technical field of thread cutting machines, and particularly relates to a thread cutting machine for clothing thread ends. Background Art

[0002] In a clothing production factory, using a thread cutting machine to process the thread ends of a batch of clothing can improve production efficiency and make the thread ends of the clothing processed cleanly and neatly, thus improving the product quality.

[0003] During clothing processing, an adsorption type thread cutting machine is usually used to trim the thread ends. The negative pressure device inside the machine starts to work, generating a strong suction force. The thread ends are adsorbed by the suction nozzle and are adsorbed to a specific cutting position. The sharp blade or other cutting device in the suction nozzle cuts off the thread ends. However, the blade generally rotates and cuts driven by a motor. In actual use, the blade trims the thread ends at different positions of the clothing as the suction nozzle moves. The cut thread ends are extracted and flow in the pipeline. The thread ends are prone to contact with the motor during the flowing process. There are usually gaps at the connection between the motor and the rotating bearing, which easily causes the thread ends to get stuck in the gap between the motor and the rotating bearing when there are more thread ends, affecting the normal driving effect of the motor on the rotating bearing, and further affecting the subsequent thread cutting effect. Moreover, sometimes the contact strength or gap between the suction nozzle and the clothing needs to be adjusted according to requirements such as the material of the clothing. However, it is difficult for traditional thread cutting machines to quickly and effectively adjust such a situation. Summary of the Utility Model

[0004] The utility model provides a thread cutting machine for clothing thread ends, which has the characteristics of improving the self - holding effect during motor driving and facilitating the adjustment of the gap between the suction nozzle and the clothing.

[0005] The utility model provides the following technical solutions: including a device block, a connecting rod, a moving pipe, a motor, a driving rod, a blade and a plurality of wire collecting holes. A support plate is fixedly connected to the inner wall of the moving pipe. A plurality of ventilation notches are formed in the side wall of the support plate. The motor is installed at the bottom end of the support plate. A protective cover is fixedly connected to the bottom end of the support plate. The motor is located inside the protective cover. The driving rod penetrates through the bottom of the protective cover. A plurality of sliding rods are slidably connected to the inner wall of the moving pipe, and all the plurality of sliding rods penetrate through the bottom of the moving pipe.

[0006] Wherein, an arc - shaped shielding plate is fixedly connected to the side wall of the driving rod. The arc - shaped shielding plate is rotatably connected to the bottom end of the protective cover. A plurality of breathable mesh plates are arranged on the side wall of the protective cover, and the positions of the plurality of breathable mesh plates are evenly distributed.

[0007] Among them, a plurality of sliding grooves are formed in the moving pipe, a hexagonal block is fixedly connected to the top end of the sliding rod, the hexagonal block is slidably connected to the inner wall of the corresponding sliding groove, screw rods are threadedly connected to the inner walls of a plurality of the sliding rods, and the screw rods are rotatably connected to the inner wall of the moving pipe.

[0008] Among them, a driven gear is fixedly connected to the top end of each of the plurality of screw rods, the driven gear is rotatably connected to the inner wall of the moving pipe, a driving toothed ring corresponding to the position of the driven gear is rotatably connected to the side wall of the moving pipe, and the driving toothed ring is meshed with the side walls of the plurality of driven gears.

[0009] Among them, hemispherical surfaces are arranged at the bottoms of a plurality of the sliding rods, and scale lines are arranged on the side walls of a plurality of the sliding rods.

[0010] The beneficial effect of the utility model is that: the motor is wrapped and protected by the protective cover, and the spherical surface at the bottom of the protective cover guides the wire head. The extraction force extracts the wire head in a form surrounding the protective cover. After the wire head is cut off, it can slide along the spherical surface at the bottom of the protective cover towards the inner wall of the moving pipe, avoiding the extraction of the cut wire head when the extraction force is at the center of the moving pipe, so that the wire head directly reaches the gap at the bottom output end of the motor, reducing the working interference of the wire head on the motor and the driving rod, and further reducing the influence on the shearing effect of the subsequent wire head.

Detailed Embodiment

[0017] Please refer to Figures 1-4 Figures 1-4 , the present utility model provides the following technical solutions: It includes a device block 1, a connecting rod 11, a moving tube 2, a motor 21, a driving rod 22, a blade 221 and a plurality of wire receiving holes 23. A support plate 3 is fixedly connected to the inner wall of the moving tube 2. A plurality of ventilation gaps 31 are formed in the side wall of the support plate 3. The motor 21 is installed at the bottom end of the support plate 3. A protective cover 32 is fixedly connected to the bottom end of the support plate 3. The motor 21 is located inside the protective cover 32. The driving rod 22 penetrates through the bottom of the protective cover 32. A plurality of sliding rods 4 are slidably connected to the inner wall of the moving tube 2. All the plurality of sliding rods 4 penetrate through the bottom of the moving tube 2.

[0018] In this implementation scheme: The device block 1 supports the connecting rod 11, the connecting rod 11 supports the moving tube 2. The moving tube 2 is the suction nozzle of the device. The bottom of the moving tube 2 contacts the clothing. The negative pressure device inside the device block 1 extracts the thread end, so that the thread end can enter the moving tube 2 through the wire receiving holes 23. The moving tube 2 supports the support plate 3, the support plate 3 supports the motor 21. The motor 21 drives the driving rod 22 to rotate, and the driving rod 22 drives a plurality of blades 221 to rotate, so that the blades 221 can cut the thread end entering the moving tube 2 during rotation. The cut thread end is extracted and stored in the device block 1 after being intercepted. The protective cover 32 wraps and protects the motor 21 externally. The connection position between the driving rod 22 and the motor 21 is inside the device block 1, so that the protective cover 32 can block the thread end from the motor 21 and the driving rod 22, avoiding the thread end reaching the connection gap between the motor 21 and the driving rod 22, and further preventing the thread end from winding and affecting the normal driving of the motor 21 to the driving rod 22. The extraction force of the device block 1 on the moving tube 2 through the connecting rod 11 acts on the position of the lower blade 221 through a plurality of ventilation gaps 31. An annular space is formed between the protective cover 32 and the moving tube 2 to guide the airflow, so that the extraction force can extract the thread end in a form surrounding the protective cover 32. After the thread end is cut, it can slide along the bottom spherical surface of the protective cover 32 towards the inner wall of the moving tube 2, facilitating the thread end to smoothly pass through the area where the protective cover 32 is located, avoiding the extraction of the cut thread end when the extraction force is at the center of the moving tube 2, so that the thread end directly reaches the gap at the bottom output end of the motor 21, further reducing the working interference of the thread end on the motor 21 and the driving rod 22, and further reducing the influence on the subsequent thread cutting effect. The sliding rods 4 extend out of the bottom of the moving tube 2. The plurality of sliding rods 4 surround the wire receiving holes 23 in a ring shape. The moving tube 2 adjusts the gap with the clothing through the plurality of sliding rods 4, preventing the plush on the clothing from being cut and causing product damage when cutting the thread of clothing such as plush fabrics. By controlling the length of the sliding rods 4 extending out of the bottom of the moving tube 2, the distance between the moving tube 2 and the clothing can be controlled, and the use is simple and efficient.

[0019] An arc-shaped shielding plate 222 is fixedly connected to the side wall of the driving rod 22. The arc-shaped shielding plate 222 is rotatably connected to the bottom end of the protective cover 32. A plurality of ventilation mesh plates 33 are arranged on the side wall of the protective cover 32, and the positions of the plurality of ventilation mesh plates 33 are evenly distributed. The driving rod 22 supports and rotationally drives the arc-shaped shielding plate 222. There is no gap between the driving rod 22 and the arc-shaped shielding plate 222. The arc-shaped shielding plate 222 shields the aperture position at the bottom of the protective cover 32 to prevent the wire from getting stuck at the connection part between the protective cover 32 and the driving rod 22. Moreover, the arc-shaped shielding plate 222 corresponds to the bottom of the protective cover 32. When the wire head is extracted, it can slide along the spherical surface of the arc-shaped shielding plate 222 to avoid the wire head getting stuck at the connection part between the edge of the arc-shaped shielding plate 222 and the protective cover 32. The ventilation mesh plates 33 enable the internal control space of the protective cover 32 to communicate with the external space, so that the heat generated when the motor 21 works can be discharged accordingly.

[0020] A plurality of sliding grooves 24 are formed in the moving pipe 2. The top end of the sliding rod 4 is fixedly connected with a hexagonal block 41. The hexagonal block 41 is slidably connected to the inner wall of the corresponding sliding groove 24. The inner walls of a plurality of sliding rods 4 are all threadedly connected with a lead screw 42. The lead screw 42 is rotatably connected to the inner wall of the moving pipe 2. The sliding groove 24 guides and limits the sliding of the hexagonal block 41 to prevent the sliding rod 4 from driving the hexagonal block 41 to disengage from the moving pipe 2, ensuring the stability of the connection between the sliding rod 4 and the moving pipe 2. The shape of the inner wall of the sliding groove 24 corresponds to that of the hexagonal block 41, so that the hexagonal block 41 will not drive the sliding rod 4 to rotate. Thus, when the lead screw 42 is rotated, the lead screw 42 can drive the sliding rod 4 up and down, so that the length of the sliding rod 4 extending out of the bottom of the moving pipe 2 can be adjusted.

[0021] The top ends of a plurality of lead screws 42 are all fixedly connected with driven gears 43. The driven gears 43 are rotatably connected to the inner wall of the moving pipe 2. A driving tooth ring 44 corresponding to the position of the driven gears 43 is rotatably connected to the side wall of the moving pipe 2. The driving tooth ring 44 is meshed and connected to the side walls of a plurality of driven gears 43. The moving pipe 2 supports the driving tooth ring 44. The sliding rod 4 is connected to the sliding rod 4 through the driven gear 43. The driven gear 43 enables the lead screw 42 to maintain a fixed position and prevents the lead screw 42 from sliding up and down. When the driving tooth ring 44 rotates, it drives a plurality of driven gears 43 to rotate synchronously. Thus, a plurality of lead screws 42 can rotate synchronously, and a plurality of sliding rods 4 can be adjusted synchronously and in the same direction.

[0022] A hemispherical surface 45 is provided at the bottom of each of a plurality of sliding rods 4, and a scale line 46 is provided on the side wall of each of the plurality of sliding rods 4; the sliding rod 4 contacts and slides with the clothing through the hemispherical surface 45, reducing the direct frictional resistance between the sliding rod 4 and the clothing fabric, improving the portability of the device when shearing and transferring thread ends at different positions of the clothing. When the sliding rod 4 adjusts the extended length, the length of the scale line 46 exposed outside the moving tube 2 changes, so that the scale line 46 can indicate the extended length of the sliding rod 4, facilitating personnel to make a judgment.

[0023] The working principle and usage process of the present utility model: When the device is in use, the distance gap between the moving tube 2 and the clothing is adjusted according to the corresponding clothing fabric. The driving gear ring 44 is rotated, and the driving gear ring 44 drives a plurality of driven gears 43 to rotate synchronously, so that a plurality of lead screws 42 can rotate synchronously, and a plurality of sliding rods 4 are adjusted synchronously and in the same direction. The length of the scale line 46 exposed outside the moving tube 2 changes, so that the scale line 46 can indicate the extended length of the sliding rod 4, facilitating personnel to make a judgment. Subsequently, the thread end is sheared. The motor 21 is controlled to drive the driving rod 22 to rotate, and the driving rod 22 drives a plurality of blades 221 to rotate. The blades 221 can shear the thread end entering the moving tube 2 during rotation. The cut thread end is drawn into the interception and storage inside the device block 1. When the thread end is drawn, it can slide along the spherical surface of the arc-shaped shielding plate 222, avoiding the thread end being stuck at the connection part between the edge of the arc-shaped shielding plate 222 and the protective cover 32, and sliding along the bottom spherical surface of the protective cover 32 towards the inner wall of the moving tube 2, facilitating the thread end to smoothly pass through the area where the protective cover 32 is located, reducing the working interference of the thread end on the motor 21 and the driving rod 22, and further reducing the influence on the subsequent shearing effect of the thread end.
