[0028] like Figure 1-4 As shown, this utility model provides a feeding and adsorption device for a collar sewing machine, including a lifting platform 1 and a base 3. The lifting platform 1 is connected to the base 3 via limiting components 2 on both sides above the base 3. The base 3 is installed on the collar sewing machine via mounting holes on both sides and bolts. A U-shaped fixing plate 4 is provided in the middle of the bottom of the lifting platform 1. A threaded post 5 is provided in the U-shaped fixing plate 4. The threaded post 5 is connected to the lead screw of the lead screw motor 6. The lead screw motor 6 is located in the middle of the base 3. The base 3 has a through hole, through which two suction pipes 9 are provided. One end of each suction pipe 9 is connected to the lifting platform 1, and the other end is connected to a four-way pipe. 11 Connection; The four-way pipe 11 is connected to the fan 14 through the suction pipe 13. The fan 14 is connected to the waste collection component 16 through the exhaust pipe 15. The suction pipe 13 and the waste collection component 16 share the same fan 14. The waste collection component 16 includes an air inlet pipe 161, a negative pressure component 162 and a waste suction pipe 163. One end of the air inlet pipe 161 is connected to one end of the exhaust pipe 15, and the other end of the air inlet pipe 161 is connected to the negative pressure component 162. The waste suction pipe 163 is provided above the negative pressure component 162. The negative pressure component 162 is located inside the waste collection component 16. The waste collection component 16 is used for adsorbing collar waste.

[0029] The base 3 is mounted on the collar sewing machine via mounting holes on both sides and bolts. The bottom end of the ball bearing 21 is connected to the base 3, and the top end of the cylindrical slider 22 is connected to the lifting platform 1. The U-shaped fixing plate 4 is fixed to the bottom of the lifting platform 1 by bolts or other fixing methods. The threaded column 5 is fixed inside the U-shaped fixing plate 4. The lead screw of the lead screw motor 6 is connected to the threaded column 5. When the lead screw motor 6 is working, it can cause the U-shaped fixing plate 4 to move in the vertical direction. The lead screw motor 6 and the fan 14 are connected to an external drive power supply, controller, connecting lines, etc. The specific structure and movement mode will not be described in detail here.

[0030] This utility model discloses a feeding and adsorption device for a collar sewing machine. At the start of collar sewing, the operator can install the device at a designated position on the machine using bolts through the mounting holes on both sides of the base 3. During operation, the lead screw motor 6 drives the lead screw to rotate synchronously. A threaded post 5 is fitted around the lead screw. When the lead screw rotates, the threaded post 5 moves the U-shaped fixing plate 4, which is fixed to it. The U-shaped fixing plate 4 is also fixed to the lifting platform 1. During its movement, the U-shaped fixing plate 4 moves the lifting platform 1. The lifting platform 1 is connected to the base 3 via limiting components 2 on both sides above the base 3. During movement, the limiting components 2 limit the movement of the lifting platform 1, preventing it from moving vertically. During the process, a deviation occurs. The suction pipe 9 is installed through the through hole, and one end of it is connected to the lifting platform 1. When the fan 14 starts working, the suction pipe 9 can make the lifting platform 1 generate suction, thereby achieving the adsorption and fixation of the collar. In addition, the fan 14 is also connected to the waste material suction component 16 through the air outlet pipe 15. The waste material suction component 16 is used for adsorbing collar waste and for adsorbing cutting waste. The waste material suction component 16 and the lifting platform 1 share the same fan 14, which saves resources. At the same time, the waste material suction component 16 is equipped with a negative pressure component 162. The negative pressure component 162 makes the waste material suction component 16 suck up waste under negative pressure. The fan 14 blows air to the waste material suction component 16 at the same time, which can prevent the waste material suction component 16 from becoming blocked.

[0031] Furthermore, in another embodiment, the waste suction assembly 16 further includes a waste discharge pipe 164, which is connected to a negative pressure assembly 162. The negative pressure assembly 162 is a negative pressure capillary tube 1621. The outer diameter of the negative pressure capillary tube 1621 is smaller than the inner diameter of the air inlet pipe 161, and the air outlet of the negative pressure capillary tube 1621 can form a negative pressure.

[0032] One end of the exhaust duct 15 is connected to the inlet duct 161, and the other end is connected to the fan 14. The exhaust duct 15 can supply air to the waste suction component 16 through the inlet duct 161. The air speed will increase as the air passes through the negative pressure thin tube 1621, thereby forming a negative pressure. The waste suction pipe 163 formed by the negative pressure can suck the waste into the waste suction component 16. The air intake of the inlet duct 161 will discharge the sucked waste from the waste discharge pipe 164, preventing blockage inside the waste suction component 16.

[0033] Furthermore, in another embodiment, a protective plate 7 is fitted on the front of the lifting platform 1. The protective plate 7 is an elastic structure and is engaged with the front of the lifting platform 1.

[0034] There is a certain gap between the lifting platform 1 and the base 3. The protective plate 7 is fitted on the lifting platform 1 to prevent relevant personnel from putting their hands or cloth into the gap between the lifting platform 1 and the base 3 during the work process, thus protecting both the personnel and the equipment.

[0035] Furthermore, in another embodiment, a dustproof net 8 is provided inside the lifting platform 1, and the dustproof net 8 is attached to the inner wall of the lifting platform 1.

[0036] The dust-proof net 8 has evenly distributed through holes. Adhering to the inner wall of the lifting platform 1, the dust-proof net 8 provides a certain degree of dust protection and also supports the fabric, preventing the hollow lifting platform 1 from directly sucking the fabric in.

[0037] Furthermore, in another embodiment, the other end of the suction pipe 9 is connected to the four-way pipe 11 via a telescopic flexible hose 10. The two ends of the telescopic flexible hose 10 are respectively sleeved on the suction pipe 9 and the four-way pipe 11, and a valve 12 is provided below the four-way pipe 11.

[0038] Valve 12 is located below the four-way pipe 11. Relevant personnel can adjust valve 12 according to actual needs to control the size of the guide surface below the four-way pipe 11, thereby achieving the effect of controlling the suction of the lifting platform 1.

[0039] Furthermore, in another embodiment, the limiting component 2 includes a ball cylindrical bearing 21 and a cylindrical slider 22. The cylindrical slider 22 is disposed on both sides below the lifting platform 1, and the ball cylindrical bearing 21 is disposed on both sides above the base 3. The cylindrical slider 22 passes through the ball cylindrical bearing 21.

[0040] The cylindrical slider 22 and the ball cylindrical bearing 21 are relatively smooth, and the friction of the cylindrical slider 22 during its movement in the ball cylindrical bearing 21 is very small, which ensures the stability of the structure.

[0041] Furthermore, in another embodiment, the base 3 is divided into two layers, which are connected by four connecting rods.

[0042] Four connecting rods connect the base 3 from top to bottom, ensuring the stability of the base 3 and extending its service life.

[0043] Working principle: When starting to sew the collar, the worker can install the collar sewing machine at the designated position through the mounting holes on both sides of the base 3 with bolts. During the operation of the lead screw motor 6, the lead screw can be driven to rotate synchronously. The threaded column 5 is sleeved on the outside of the lead screw. When the lead screw rotates, the threaded column 5 will drive the U-shaped fixing plate 4 fixed to it to move. The U-shaped fixing plate 4 is fixed to the lifting platform 1. During the movement of the U-shaped fixing plate 4, the lifting platform 1 can be driven to move. The lifting platform 1 is connected to the base 3 through the limiting components 2 on both sides above the base 3. During the movement of the lifting platform 1, the limiting components 2 can limit the lifting platform 1 and prevent the lifting platform 1 from deviating during the vertical movement.

[0044] The suction pipe 9 is installed through the through hole, and one end of it is connected to the lifting platform 1. During the operation, the relevant personnel can control the fan 14 to start working. When the fan 14 starts working, it can generate suction on the lifting platform 1 through the suction pipe 9, thereby achieving the adsorption and fixation of the collar. In addition, the staff can also install the waste suction pipe 163 at the cutting position of the sewing machine. During the cutting process, the air outlet pipe 15 can supply air to the waste suction component 16 through the air inlet pipe 161. The air speed will increase as the air enters through the negative pressure thin pipe 1621, thereby forming a negative pressure. The waste suction pipe 163 can suck the waste into the waste suction component 16. The air inlet pipe 161 will discharge the sucked waste from the waste discharge pipe 164, preventing the waste suction component 16 from becoming blocked. The waste suction component 16 and the lifting platform 1 share the same fan 14, saving resources.
