Description

Technical Field

[0001] This utility model belongs to the field of knitted garment production technology, specifically relating to a dust collection device for knitted garment production. Background Technology

[0002] Knitted garments are a type of clothing made from knitted fabrics, including but not limited to knitted underwear, outerwear, gloves, and socks. These garments can be made by hand-knitting pieces and then sewing them together, or by first knitting the fabric into greige and then cutting and sewing it. Compared to traditional machine-knitted garments, knitted garments are known for their soft texture, good drape, wrinkle resistance, breathability, and superior stretch and elasticity, making them more form-fitting and comfortable for the wearer.

[0003] During the production of knitted garments, workers inevitably generate dust, loose threads, and fine lint due to their constant contact with the fabric. These impurities not only gradually disperse into the surrounding air, reducing air quality, but can also be inhaled by workers, posing a threat to their respiratory health. Therefore, implementing effective cleaning and filtration measures is crucial to protecting worker health and improving air quality in the production environment.

[0004] Chinese utility model patent CN222049540U discloses a dust collection device for knitted garment production, comprising: an operating table frame, supports at the four lower corners of the operating table frame, a vacuum cleaner body at the rear end of the operating table frame, casters at the four lower corners of the vacuum cleaner body, an air vent at the left end of the vacuum cleaner body, and a connecting pipe at the upper end of the vacuum cleaner body. This utility model uses a extraction mechanism to quickly remove dust collected within the vacuum cleaner body, and the dust collection box has a large storage space for easy extraction. A rotating clamping mechanism quickly fixes the clamping blocks to the upper rear end of the operating table frame, facilitating the subsequent positioning of the connecting pipe on the first and second clamping blocks. The device effectively collects and processes dust in the workspace, effectively preventing its impact on the health of workers, and offers good flexibility. However, it requires frequent disassembly and reassembly when changing positions, and the device is quite inconvenient when installed on the side of the operating table. Utility Model Content

The pin 23 elastically abuts against the mounting base 18 via the second spring 24. The pin 23 is movably inserted into the sliding hole 21. The pin 23 has a handle 25, and the button cover 22 has a sliding opening 26. The handle 25 is located inside the sliding opening 26. A silicone ring 27 is fixedly installed on the valve plate 11. The support plate 5 is sealed to the dust collection funnel 6 via a sealing gasket 28. The inner wall of the first mounting hole 8 has an annular rib 29, and the valve body 10 has an annular groove 30.

[0024] Through the above technical solution, the workbench 2 of this utility model is provided with an assembly port 4, and a support plate 5 is fixedly installed on the assembly port 4. A dust collection funnel 6 is fixedly installed at the bottom of the support plate 5. The dust collection funnel 6 is connected to the vacuum cleaner 3 through a pipe 7. The support plate 5 is provided with multiple first assembly holes 8, and a valve switch assembly 9 is fixedly installed on the first assembly holes 8. During operation, the vacuum cleaner 3 is started. According to the work position, the user opens the valve switch assembly 9 at the corresponding position by pressing the valve opening button 19. The suction negative pressure generated by the vacuum cleaner 3 passes through the valve switch assembly 9 on the workbench 2, adsorbing and removing dust, lint, and other impurities on the workbench 2. When changing work positions, the user closes the valve switch assembly 9 at the current work position by pressing the valve closing button 20, and then opens the valve switch assembly 9 at the corresponding work position, quickly completing the work position change and improving production efficiency.

[0025] Example 2:

[0026] like Figures 1-7As shown, this embodiment provides a dust collection device for knitted garment production, whose main structure includes a frame 1, a workbench 2, and a vacuum cleaner 3. The frame 1 serves as the supporting structure for the entire device, ensuring its stability in the production environment. The workbench 2 is fixedly mounted on the frame 1 and is designed to hold various materials and tools used in knitted garment production. The vacuum cleaner 3 is also fixedly mounted on the frame 1 and is connected to a dust collection funnel 6 via a pipe 7, responsible for generating and maintaining negative pressure within the system.

[0027] The workbench 2 is equipped with multiple assembly ports 4, each with a fixed support plate 5. A dust collection funnel 6 is fixedly installed at the bottom of the support plate 5 to ensure effective collection of dust and thread ends generated during production. The dust collection funnel 6 is connected to the vacuum cleaner 3 via a pipe 7, forming a complete dust collection system.

[0028] The support plate 5 has multiple first mounting holes 8, and a valve switch assembly 9 is fixedly installed in each mounting hole. The valve switch assembly 9 includes a valve body 10 and a valve plate 11. The valve body 10 is movably mounted with the valve plate 11 via a connecting rod 12. A top block 14 is fixedly installed at the end of the connecting rod 12 via bolts 13. The top block 14 elastically abuts against the valve plate 11 via a first spring 15 to ensure that the valve plate 11 can automatically close when no force is applied.

[0029] The valve body 10 is designed with a dust suction hole 16, a second mounting hole 17, and a mounting base 18. The dust suction holes 16 are symmetrically arranged on the valve body 10 and are used to connect to the dust suction holes 16 on the surface of the workbench 2. The vacuum cleaner 3 sucks up dust through the dust suction holes 16. The second mounting hole 17 is used to install the valve opening button 19, which is fixedly installed on the valve plate 11, allowing the operator to easily open or close the vacuuming device as needed. The mounting base 18 is fixedly installed with the valve closing button 20, ensuring quick operation when the valve needs to be closed.

[0030] When the vacuum cleaner 3 is started, a continuous negative pressure is generated within the system. The operator presses the corresponding valve opening button 19 according to the current workstation position, causing the valve plate 11 to open. The negative pressure is then transmitted through the suction holes 16 to the suction holes 16 on the surface of the workbench 2. Dust and fine impurities such as lint on the workbench 2 are sucked into the dust collection funnel 6 and enter the vacuum cleaner 3 through the pipe 7, achieving efficient dust removal. When a workstation needs to be changed, the operator simply presses the valve closing button 20 of the current workstation to close the valve and opens the corresponding valve at the new workstation, completing the workstation switch without needing to move or reinstall the vacuuming device, greatly improving production efficiency and operational convenience.

[0031] Example 3:

[0032] This embodiment further optimizes the structure and operation of the mounting base 18 and the valve closing button 20 based on embodiment two. The mounting base 18 is electrically connected to the second mounting hole 17 through the sliding hole 21, ensuring that the valve plate 11 can move smoothly during opening and closing. The valve closing button 20 includes a button cover 22, a pin 23, and a second spring 24. The button cover 22, as an externally visible operating part, protects the internal structure of the valve closing button 20 from the intrusion of dust and impurities.

[0033] The pin 23 elastically abuts against the mounting base 18 via the second spring 24. The pin 23 is movably inserted through the sliding hole 21, allowing for flexible operation. When the valve needs to be closed, the operator pushes the handle 25, moving the pin 23 within the sliding hole 21, releasing the valve button, and subsequently operating the valve plate 11 to close the suction port 16, cutting off the negative pressure channel and stopping the suction function. The button cover 22 has a sliding opening 26, within which the handle 25 is located, ensuring flexible operation when the operator pushes the handle 25.

[0034] Example 4:

[0035] Based on Embodiment 2, the sealing structure of the valve plate 11 was further optimized. A silicone ring 27 is fixedly installed on the valve plate 11, surrounding the periphery of the valve plate 11, enhancing the sealing effect between the valve plate 11 and the valve body 10. The silicone material has good elasticity and wear resistance, and can maintain stable sealing performance during frequent opening and closing operations of the valve plate 11.

[0036] When the valve plate 11 is closed, the silicone ring 27 is in full contact with the sealing surface of the valve body 10, forming a tight seal. At the same time, the elastic properties of the silicone ring 27 allow the valve plate 11 to move flexibly when subjected to the force of the connecting rod 12 and the top block 14, and to quickly rebound to the closed position after the force is released, ensuring reliable valve closure.

[0037] Example 5:

[0038] This embodiment further optimizes the sealing connection structure between the support plate 5 and the dust collection funnel 6, based on embodiment two. The support plate 5 is sealed to the dust collection funnel 6 by a sealing gasket 28, which covers the contact surface between the support plate 5 and the dust collection funnel 6 to ensure airtightness between them.

[0039] The sealing gasket 28 is made of a highly elastic material, which can effectively fill the tiny gaps between the support plate 5 and the dust collection funnel 6, preventing air leakage or dust from escaping from the connection. The sealing gasket 28 not only maintains a negative pressure environment within the system during production, but also prevents external dust from drifting to the outside through the connection, improving dust collection efficiency and the cleanliness of the working environment.

[0040] Example 6:

[0041] Based on Embodiment 2, this embodiment further optimizes the mating structure between the annular rib 29 on the inner wall of the first assembly hole 8 and the annular groove 30 on the valve body 10. The inner wall of the first assembly hole 8 of the support plate 5 is provided with an annular rib 29, and the valve body 10 is provided with an annular groove 30. This structural design ensures that the valve body 10 can be firmly and stably fixed when installed into the first assembly hole 8.

[0042] When the valve body 10 is inserted into the first mounting hole 8, the annular rib 29 and the annular groove 30 cooperate to lock the position of the valve body 10, preventing the valve body 10 from shifting or loosening due to vibration or other external forces during operation. The cooperation between the annular rib 29 and the annular groove 30 not only improves the connection strength between the valve body 10 and the support plate 5, but also simplifies the installation and disassembly process of the valve switch assembly 9, facilitating daily maintenance and replacement.
