Description

Technical Field

[0001] This utility model relates to the field of sewing machine needle plate technology, specifically a computerized sewing machine with needle plate cleaning function. Background Technology

[0002] A sewing machine is a machine that uses one or more sewing threads to create one or more stitches on fabric, allowing one or more layers of fabric to interweave or sew together. Sewing machines can sew fabrics such as cotton, linen, silk, wool, and synthetic fibers, as well as products made of leather, plastic, and paper. The stitches produced are neat, beautiful, flat, and strong. Sewing machines are fast, easy to use, and have given rise to art forms such as hand-pushed embroidery and computer embroidery. With the increasing competition in the sewing machinery manufacturing industry, mergers and acquisitions and capital operations among large sewing machinery manufacturers are becoming more frequent. Excellent domestic sewing machinery manufacturers are paying more and more attention to research on the industry market, especially in-depth research on the industrial development environment and product buyers. As a result, a large number of excellent domestic sewing machinery brands have rapidly emerged.

[0003] In existing sewing processes, fabric lint is generated and accumulates around the feed dog, especially in the middle of it. Because current sewing machines cannot automatically clean the lint around the feed dog, the lint accumulates more and more with increased workload. This accumulation forms a thick layer of lint between the bottom of the center rib of the needle plate and the feed dog in a double-needle flatbed sewing machine. During the movement of the feed dog, this lint layer compresses the center rib, causing the feed dog to push the needle plate upwards, displacing the adjusted standard height and affecting sewing quality. Secondly, over time, accumulated fabric color and dust remain on the needle plate surface when sewing new fabric, causing color bleeding. Existing sewing machine needle plates cannot be automatically cleaned and require manual cleaning, which is inconvenient. Utility Model Content

[0004] To address the shortcomings mentioned in the background section, the present invention aims to provide a computerized sewing machine with a needle plate cleaning function. Through the cooperation of a dust extraction device and an extension tube, automatic cleaning of the needle plate is achieved, preventing fabric lint accumulation from compressing the feed dog and center rib, ensuring the standard height of the feed dog, and improving sewing quality. Simultaneously, the collection box design collects and filters fabric lint and dust, reducing manual cleaning workload and improving ease of use. Furthermore, the extendable extension tube and the magnetic adsorption design of the collection box enhance the applicability and stability of this invention.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0023] like Figures 1-4 As shown, a computerized sewing machine with a needle plate cleaning function includes a needle plate 1. The needle plate 1 has needle grooves 2 extending vertically through its top and bottom, and mounting holes 3 extending vertically through its bottom and top. A flow cavity 4 is formed inside the needle plate 1, communicating with the needle grooves 2. A lower suction port 5 is formed at the bottom of the needle plate 1. The needle plate 1 consists of upper and lower parts. Multiple alignment rods 6 are fixedly connected to the lower part of the needle plate 1. Alignment holes 7 are formed in the upper part of the needle plate 1, and the alignment rods 6 are located inside the alignment holes 7. When implementing the computerized sewing machine of this invention, the needle plate 1 is first installed on the sewing machine through the mounting holes 3, ensuring the accurate positioning of the needle grooves 2 and the mounting holes 3. The needle plate 1, consisting of upper and lower parts, achieves precise alignment through the alignment rods 6 and the alignment holes 7, ensuring the stability and reliability of the needle plate 1 structure. This needle plate 1 has the same specifications as needle plates 1 in the prior art, requiring no changes to the sewing machine and is applicable to most sewing machines, thus increasing its applicability.

[0024] One side of the flow cavity 4 is connected to an extension tube 8. A connecting piece 9 is provided at the end of the extension tube 8. A through-hole 10 is provided on the connecting piece 9. A threaded opening 11 is provided on the upper part of the needle plate 1. The connecting piece 9 is fixed to the threaded opening 11 of the needle plate 1 by screws.

[0025] The extension tube 8 is a telescopic tube with a flat cross-sectional shape. This allows for the installation of the extension tube 8. The telescopic nature of the extension tube 8 facilitates length adjustment, and its flat cross-sectional shape makes it easy to connect to vacuum cleaners while reducing the space occupied. Furthermore, the flat shape minimizes the protrusion height, preventing interference with the sewing process.

[0026] The end of the extension tube 8 away from the needle plate 1 is connected to a collection box 12. A fan 13 is fitted into the top of the collection box 12. The fan 13 is powered by an external power source. A partition 14 is provided inside the collection box 12. The partition 14 is supported by sponge.

[0027] The partition 14 divides the internal space of the collection box 12 into upper and lower parts. The lower part of the collection box 12 is connected to the extension pipe 8, and the fan 13 is located in the upper part of the collection box 12. A waste outlet 15 is provided on the collection box 12, connected to the lower part of the collection box 12, and a sealing cover 16 is connected to the waste outlet 15. The fan 13, located in the upper part of the collection box 12, ensures smooth airflow through the collection box 12 and draws in fabric scraps and dust. To facilitate cleaning of fabric scraps and dust inside the collection box 12, a waste outlet 15 is provided, connected to the lower part of the collection box 12. When fabric scraps and dust accumulate to a certain level inside the collection box 12, the waste outlet 15 can be opened to empty the waste. The waste outlet 15 is connected to the sealing cover 16 to prevent fabric scraps and dust from scattering if the waste outlet 15 is accidentally opened during sewing.

[0028] The bottom of the collection box 12 is provided with an adsorption block 17, which is made of magnetic material. It can be easily adsorbed onto the sewing machine's worktable to fix the collection box 12 and prevent it from moving or tipping over during sewing.

[0029] Working principle:

[0030] Before the sewing machine starts working, connect the extension tube 8 to the needle plate 1, and then place the collection box 12 in a suitable location. Because the bottom has an adsorption block 17 made of magnetic material, it can be easily adsorbed onto the sewing machine's worktable, fixing the collection box 12 and preventing it from moving or tipping over during sewing. During sewing, the fan 13 continuously operates, expelling air from inside the collection box 12, creating a negative pressure state within the collection box 12, extension tube 8, and flow chamber 4. Fabric scraps first enter the needle groove 2. Since the needle groove 2 is connected to the flow chamber 4, it will adsorb fabric scraps into the flow chamber 4. Some unadsorbed fabric scraps will fall downwards around the feed dog, and finally, the fabric scraps around the feed dog are sucked in through the lower adsorption port 5, and then enter the collection box 12 through the extension tube 8. The partition 14 inside the collection box 12 filters out fabric scraps and dust, causing them to remain in the lower part of the collection box 12. When the fabric scraps and dust inside the collection box 12 accumulate to a certain level, the waste outlet 15 can be opened to pour out the waste. The waste outlet 15 is connected to a sealing cover 16 to prevent fabric scraps and dust from scattering if the waste outlet 15 is accidentally opened during sewing.
