Description

Technical Field

[0001] This utility model relates to the field of textile technology, and more specifically, to an independent suction device for textiles. Background Technology

[0002] In the process of textile and garment sewing, processes requiring hemming and sewing are frequently encountered, such as the chest pocket of a shirt, the back pocket of trousers, the turtleback of a polo shirt, and the vents at the hem. These processes require folding the fabric before sewing. Currently, some template sewing machines on the market are equipped with suction devices. These devices use an opening in the machine's table to install a suction plate, with a suction chamber below, and a suction conversion box to draw the fabric in when needed. However, existing suction devices have the following drawbacks:

[0003] 1. Functional limitations: The suction device is usually integrated with the main unit platform and can only be used on machines with this function. For machines that do not have a built-in suction function, users have to buy a new machine, which increases costs.

[0004] 2. Insufficient flexibility: Because the suction device is installed together with the main unit, it occupies part of the machine's operating space and cannot be flexibly combined with multiple machines. Furthermore, when the machine is running, the suction area and the machine's operating area often conflict, preventing them from working simultaneously.

[0005] 3. Difficult to install: For some machines, such as flat sewing machines, which use wooden tables, it is difficult to install a suction function due to the small operating area. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0033] Example: Figures 1 to 7As shown, an independent suction device for textiles includes a frame 4 and a fan 5. The frame 4 is a frame structure welded from multiple square tubes, providing stable support. A suction chamber 16 is fixed to the top of the frame 4. A porous suction plate 2 for adsorbing fabric is sealed to the upper side of the suction chamber 16. A suction conversion box 7 is installed at the bottom of the suction chamber 16. A suction port 20 is opened at the top of the suction conversion box 7. The suction conversion box 7 is connected to the inside of the suction chamber 16 through the suction port 20. An air inlet 22 is opened at the bottom of the suction conversion box 7. A cylinder 17 is installed on the outside of the air inlet 22. The output end of the cylinder 17 is located inside the suction conversion box 7. A rubber plug 21 with a diameter larger than the suction port 20 is installed on it. The opening and closing of the suction port 20 can be controlled by the cylinder 17 and the rubber plug 21, thus enabling the suction to be opened and closed without shutting off the fan. With the machine 5, the porous suction plate 2 adsorbs and releases the fabric. The suction conversion box 7 is connected to the left side of the pipe connector 18. The fan 5 is installed at the bottom inside the frame 4. The output end of the fan 5 is sealed to the pipe connector 18 through the air pipe 8 and is connected to the suction conversion box 7 through the air pipe 8 to provide suction power. The suction switch 11 is installed on the frame 4 at the front of the suction chamber 16. The suction switch 11 is electrically connected to the fan 5 and is used to control the start and stop of the fan 5. The suction switch 11 is provided with an air intake pressure regulating valve 24 on the left side. The air intake pressure regulating valve 24 is provided with a power switch 23 on the left side.

The output end of the suction switch 11 is connected to the cylinder 17 through the air pipe. This design solves the problems of functional limitations, lack of flexibility and difficulty in installation of existing suction devices.

[0034] In this embodiment, the suction cavity 16 is provided with a grid-like serrated plate 19, which is fixedly connected to the porous suction plate 2. The serrated plate 19 supports the suction plate without blocking the suction holes, ensuring suction power and preventing the suction plate from sinking during suction. At the same time, the grid-like serrated plate 19 can guide the airflow to be evenly distributed inside the suction cavity 16, thereby achieving uniform adsorption of the fabric.

[0035] In this embodiment, an L-shaped tabletop extension plate 9 is provided on the rear side of the frame 4. Vertical adjustment slots 15 are provided on both the vertical surface of the tabletop extension plate 9 and on the frame 4. The tabletop extension plate 9 is adjustablely connected to the frame 4 via bolts and the vertical adjustment slots 15. The design of the vertical adjustment slots 15 allows the tabletop extension plate 9 to move up and down within a certain range, achieving a flush position with the perforated suction plate 2, thus accommodating suction plates of different materials, specifications, and thicknesses to meet various work requirements.

[0036] In this embodiment, two sets of template support rods 1 are symmetrically arranged on the upper side of the tabletop extension plate 9. Multiple sets of horizontal adjustment slots 14 are opened on the upper surface of the tabletop extension plate 9. The two sets of template support rods 1 are adjustablely connected to the tabletop extension plate 9 by bolts and the horizontal adjustment slots 14. The adjustable connection of the horizontal adjustment slots 14 can realize the horizontal movement adjustment of the template support rods 1, so that the device can adapt to fabrics or templates of different widths. Two sets of infrared positioning modules 3 are symmetrically installed on the inner side of the two sets of template support rods 1. An infrared positioning switch 10 is provided on the frame 4.

One set of horizontal adjustment slots 14 is provided with an adjustable template positioning post 13. The template positioning post 13 can be installed in any horizontal adjustment slot 14 to realize the positioning function of the template at different positions. The template positioning post 13 is used to accurately fix and position the template to ensure the positional stability of the template. At the same time, the template positioning post 13 can be installed in different horizontal adjustment slots 14 and can be adjusted horizontally to adapt to different styles of templates.

[0038] In this embodiment, multiple sets of mounting slots 12 are provided on the template support rod 1, and the infrared positioning module 3 is fixed to the mounting slots 12 by bolts. The mounting slots 12 provide fixed points for the installation of the infrared positioning module 3, and the design of multiple sets of mounting slots 12 facilitates the adjustment of the installation height of the infrared positioning module 3 to adapt to the usage requirements of different working conditions.

[0039] In this embodiment, adjustable feet 6 are installed at the four corners of the bottom of the frame 4. The height of the device can be adjusted by the adjustable feet 6. The height of the table can be adjusted independently according to the model to be matched, so as to ensure that the surface of the perforated suction plate 2 is completely flat with the table of the equipment to be assembled, and to ensure the normal operation of the suction function.

[0040] In this embodiment, the frame 4 is a frame structure made of multiple square tubes welded together. The suction cavity 16 is formed by adding a suction base plate to the bottom of the square tube at the top of the frame 4, and forming a suction space with the perforated suction plate 2 above the frame. The suction cavity 16 adopts a modular design, which uses the parts of the device itself to assemble and splice, saving parts and production costs.

[0041] In this embodiment, the bottom of the suction chamber 16 is provided with an air volume adjustment port 25 for adjusting the suction power of the porous suction plate 2. The air volume adjustment port can control the suction power of the porous suction plate 2 according to the size of its opening to adapt to different fabrics and different suction requirements. The air volume adjustment port is a lever-type adjustment plate, and the opening size of the air volume adjustment port can be adjusted by adjusting the position of the lever.

[0042] It should be noted that the suction switch 11 in this embodiment is a manual solenoid valve, which can be controlled in various ways, such as by adding a small circuit board button or by foot pedal control of the solenoid valve.

[0043] In addition, the perforated suction plate 2 can be used in various styles, such as standard mesh plate, fiberglass plate, stainless steel plate, etc.

[0044] The working principle of this independent suction device for textiles:

[0045] In actual use, move the device next to the equipment to be assembled. Adjust the adjustable foot support 6 according to work requirements to make the perforated suction plate 2 completely flush with the table surface of the equipment to be assembled. Adjust the position of the template support rod 1 according to the width of the template, and then place the template on the perforated suction plate 2 and position it using the template positioning column 13. At the same time, install the infrared positioning module 3 on the template support rod 1 and adjust the installation height of the infrared positioning module 3 as needed. Connect the air intake pressure regulating valve 24 to the existing air compressor in the factory through an air pipe, connect the air intake pressure regulating valve 24 to the suction switch 11 through an air pipe, and connect the suction switch 11 to the cylinder 17 through an air pipe. Start the fan 5 to generate suction power. Ensure that the suction port 20 of the suction conversion box 7 is in the open state, retract the cylinder 17, and remove the rubber plug 21 from the suction port 20. Place the fabric on the perforated suction plate 2. The airflow evenly adsorbs the fabric through the perforated suction plate 2, realizing the functions of adsorption and hemming of the fabric. The cylinder 17 can be extended and retracted by the suction switch 11. The cylinder 17, in conjunction with the rubber plug 21, controls the opening and closing of the suction port 20, thus enabling the porous suction plate 2 to adsorb and release fabric without shutting down the fan 5. When the cylinder 17 moves the rubber plug 21 downwards, it seals the bottom air inlet 22, allowing airflow through the suction chamber. At this time, the porous suction plate 2 performs suction, achieving the adsorption function. When the rubber plug 21 moves upwards, closing the suction port 20, the lower air inlet 22 opens, allowing air to be drawn in. At this time, the porous suction plate 2 stops its suction function.

[0046] In summary, this independent suction device for textiles generates suction power through the fan 5, and combined with the control of the suction conversion box 7, cylinder 17 and rubber plug 21, as well as the design of auxiliary components such as the serrated plate 19, template support rod 1, and infrared positioning module 3, it achieves uniform adsorption, precise positioning and flexible adjustment of the fabric, and solves the problems of functional limitations, insufficient flexibility and difficult installation of existing suction devices.

[0047] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
