Description

Technical Field

[0001] This utility model relates to the field of embroidery machine technology, specifically to a negative pressure adsorption and collection device for waste thread in embroidery machines. Background Technology

[0002] Embroidery machines, also known as computerized embroidery machines, are the most advanced embroidery machinery of our time. They enable high-speed and high-efficiency execution of traditional hand embroidery, and can achieve the "multi-layered, multi-functional, uniform, and perfect" requirements that hand embroidery cannot reach. During operation, embroidery machines generate waste thread, which needs to be processed promptly to prevent blockages. Currently, negative pressure adsorption collection structures are mainly used for this purpose. For example, Chinese utility model application CN212892744U discloses a waste material collection device for embroidery processing, which includes a transfer plate with a handle welded to its top and a fixed opening on one side of the top. However, this handheld negative pressure adsorption structure is labor-intensive. Therefore, negative pressure adsorption structures that are directly fixed to the embroidery machine have also emerged, eliminating the need for manual handling. However, these structures still have the following drawbacks: The current negative pressure adsorption collection structure, which is directly fixed to the embroidery machine, has an invariably fixed adsorption port. However, the waste threads produced by the embroidery machine sometimes scatter far from the adsorption port, making them difficult to remove in time and thus impractical.

[0003] Therefore, we propose a negative pressure adsorption and collection device for waste embroidery thread to solve the above problems. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example 1: Please see Figure 1-2 This utility model provides a technical solution: a negative pressure adsorption and collection device for waste embroidery machine threads, including a collection chamber 1, a support block 2 fixedly connected to one side of the collection chamber 1, a main square tube 3 fixedly connected to the support block 2, an outer circular chamber 4 fixedly connected and connected to the end of the main square tube 3, an inner circular chamber 5 rotatably arranged inside the outer circular chamber 4, a sub-square tube 6 fixedly connected and connected to the side wall of the inner circular chamber 5, a collection head 7 fixedly connected and connected to the end of the sub-square tube 6, an arc-shaped opening 9 opened on the side of the outer circular chamber 4 near the sub-square tube 6, and the end of the sub-square tube 6 slidably connected to the arc-shaped opening 9, and an arc-shaped material inlet 10 opened on the side of the inner circular chamber 5 near the main square tube 3. The collection head 7 adsorbs waste threads. During adsorption, the inner circular chamber 5 can rotate inside the outer circular chamber 4 in a reciprocating rotation manner. In this way, the position of the collection head 7 will continuously change back and forth, so that even if the waste threads are scattered and floating, they can still be adsorbed and collected in time, making it more practical.

[0016] Example 2: Please see Figure 1-4 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. Two rotating columns 8 are fixedly connected to both sides of the middle of the inner circular compartment 5. The rotating columns 8 penetrate the side wall of the main square tube 3 and are rotatably sleeved on the side wall of the main square tube 3. The drive compartment 12 is fixedly connected to the side wall of the outer circular compartment 4.

[0017] The end of the rotating column 8 near the drive chamber 12 is located inside the drive chamber 12 and is horizontally fixed to the drive shaft 13. The drive gear 14 is fixedly sleeved on the drive shaft 13, and the U-shaped frame 15 is rotatably sleeved on the drive shaft 13. The drive gear 14 is located inside the U-shaped frame 15.

[0018] The inner end of the U-shaped frame 15 is fixed to the slider 16. A T-shaped slide bar 17 is slidably arranged on the slider 16. A rack 19 is fixed to the side of the T-shaped slide bar 17 near the drive gear 14. The rack 19 meshes with the drive gear 14. A T-shaped sliding opening 18 is opened on the slider 16. The T-shaped sliding opening 18 slidably fits the T-shaped slide bar 17.

[0019] A servo geared motor 20 is fixedly connected to the side wall of the outer circular compartment 4 inside the drive compartment 12. A shaft column 21 is rotatably connected to the side wall of the outer circular compartment 4 near the servo geared motor 20. A drive gear 22 is fixedly connected to the shaft end of the servo geared motor 20. A driven gear 23 is fixedly sleeved on the shaft column 21. The drive gear 22 meshes with the driven gear 23. One end of a short arm 24 is fixedly connected to the end of the shaft column 21. The other end of the short arm 24 is rotatably connected to a power rod 25. A T-shaped slide bar 17 and the end of a rack 19 are fixedly connected to the end of the power rod 25. The servo geared motor 20 drives the shaft column 21 to rotate, which pulls the power rod 25 to continuously change its position, causing the rack 19 to slide back and forth continuously and adjust its angle, thereby driving the drive gear 14 to rotate back and forth, realizing the reciprocating rotation of the inner circular compartment 5 inside the outer circular compartment 4.

[0020] A negative pressure fan 26 is fixedly connected to the bottom of the collection chamber 1. The output end of the negative pressure fan 26 is fixedly connected to and connected to a pneumatic switching valve 27. The pneumatic switching valve 27 is fixedly connected to and connected to two negative pressure pipes 28. The ends of the negative pressure pipes 28 pass through the side wall of the collection chamber 1 and are located inside the collection chamber 1. One end of the negative pressure pipe 28 located inside the collection chamber 1 is fixedly connected to a partition net 29. The top surface of the end of the main square pipe 3 is fixedly connected to and connected to one end of the feed pipe 11. The other end of the feed pipe 11 passes through the top surface of the collection chamber 1 and is located inside the collection chamber 1. Different negative pressure pipes 28 can be switched through the pneumatic switching valve 27. When too much waste wire accumulates at the partition net 29 and causes blockage, another negative pressure pipe 28 is replaced to ensure the negative pressure in the collection chamber 1.

[0021] Example 3: Please see Figure 1-4 This is the third embodiment of the present invention, which is based on the above two embodiments. When using the present invention, the collecting head 7 should be located at the embroidery machine. During use, the negative pressure fan 26 generates negative pressure on the collecting chamber 1, and at the same time, the collecting head 7 reciprocates to adjust its position to suck up and collect the waste thread. The present invention uses the collecting head 7 to absorb the waste thread. During absorption, the inner circular chamber 5 can rotate inside the outer circular chamber 4. The rotation is a reciprocating rotation, so the position of the collecting head 7 will constantly change back and forth. Even if the waste thread is scattered and floating, it can still be absorbed and collected in time, making it more practical.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
