Description

Technical Field

[0001] The utility model belongs to the technical field of mask cloth cutting, and in particular relates to a cloth cutting device for mask production and processing. Background Art

[0002] Mask production primarily involves nose bridge strips, ear straps, and non-woven fabrics. Non-woven fabrics are the primary raw material for masks, offering excellent filtering, shielding, thermal insulation, and oil absorption properties. They are typically made of polypropylene and can be categorized into spunbond, meltblown, and air-through types. Meltblown, a key material for mask filtration, has a small fiber diameter and is highly effective at blocking tiny particles such as bacteria and viruses.

[0003] During the transportation of non-woven fabrics, cloth rollers are usually used for rolling and transportation, and then they are stacked together for transportation. Since the fabrics are stacked together, wrinkles and creases are likely to appear on the surface of the non-woven fabrics. These wrinkles and creases will affect the shape of the cut non-woven fabrics when the non-woven fabrics are cut and produced, which may easily lead to deviations in the shape of the cut non-woven fabrics.

[0012] Beneficial effects:

[0013] First, by setting a circular cylinder, when the fixed seat descends, the circular cylinder first contacts the fabric on the support plate, and a torsion spring is installed at the connection between the rotating rod and the mounting plate. The torsion spring controls the support rod to tilt outward. As the fixed seat descends, the circular cylinders on both sides contact the fabric. As the fixed seat presses down, the two support rods rotate outward, pushing the fabric to both sides, making the fabric taut, reducing wrinkles, and facilitating cutting;

[0014] Secondly, by setting an air cylinder, when the fixed seat descends, the vertical pipe and the piston are pulled down, and the piston squeezes the gas in the air cylinder. The gas enters the vertical pipe through the air hole and is ejected through the adsorption hole on the lower surface of the circular shell. Before cutting, the surface of the cloth is cleaned by the air flow to avoid residual thread ends.

When the fixed seat rises and resets, the piston is pushed upward through the vertical pipe, and the gas enters the air cylinder through the adsorption hole. The circular shell adsorbs the cloth through the adsorption hole, so that the cut cloth is separated from the long cloth. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in combination with the accompanying drawings by way of examples.

[0023] like Figures 1 to 4 As shown, the embodiment of the present invention proposes a cloth cutting device for mask production and processing, including a base 1, the upper surface of the base 1 is fixedly connected to a support plate 2, a fixed seat 3 is provided above the support plate 2, the bottom surface of the fixed seat 3 is fixedly connected to an annular blade 4, the annular blade 4 is provided with serrations, two mounting plates 5 are fixedly connected on both sides of the fixed seat 3, a rotating rod 6 is rotatably connected between the two opposite mounting plates 5, the outer side of the rotating rod 6 is fixedly connected to a support rod 7, one end of the support rod 7 is fixedly connected to a round rod 8, the outer side of the round rod 8 is rotatably connected to a round cylinder 9, the upper surface of the base 1 is fixedly connected to two vertical plates 10, each of the vertical plates 10 is provided with a square through groove, each of the square through grooves is slidably connected to a sliding seat 11, and the two sliding seats 11 are connected The horizontal plate 12 is fixedly connected to the vertical pipe 13, which passes through the horizontal plate 12 and is fixedly connected to the fixed seat 3. When in use, the mask cloth is spread flat on the support plate 2, and the horizontal plate 12 is pressed down. The horizontal plate 12 presses down the annular blade 4, and the cloth is cut by the annular blade 4. The height of the circular cylinder 9 is lower than the annular blade 4. When the fixed seat 3 descends, the circular cylinder 9 first contacts the cloth on the support plate 2. A torsion spring is installed at the connection between the rotating rod 6 and the mounting plate 5. The torsion spring controls the support rod 7 to tilt outward. As the fixed seat 3 descends, the circular cylinders 9 on both sides contact the cloth. As the fixed seat 3 is pressed down, the two support rods 7 rotate outward and push the cloth to both sides, making the cloth taut, reducing wrinkles and facilitating cutting.

[0024] like Figure 1 and Figure 4 As shown, a mounting groove is provided on the support plate 2, and a cutting table 14 is fixedly connected in the mounting groove. There is a gap between the cutting table 14 and the side wall of the mounting groove. The cutting table 14 cooperates with the annular blade 4. During the cloth cutting process, the annular blade 4 will move downward, and its inner side will be in close contact with the outer side of the cutting table 14. The serrated part of the annular blade 4 will pass through the cloth and extend into the gap between the cutting table 14 and the mounting groove. This design enables the cloth to be easily cut and can be smoothly separated during the cutting process, thereby improving the cutting efficiency and accuracy.

[0025] like Figure 4 As shown, the upper surfaces of the two vertical plates 10 are fixedly connected to the fixed plate 15, the upper surface of the fixed plate 15 is fixedly connected to the air cylinder 16, the piston 17 is slidably connected in the air cylinder 16, the piston 17 is fixedly connected to the vertical pipe 13, the side wall of the vertical pipe 13 is provided with an air hole, the vertical pipe 13 passes through the air cylinder 16 and the fixed plate 15 and is slidably connected to the air cylinder 16 and the fixed plate 15, the lower end of the vertical pipe 13 is connected to the circular shell 18, the circular shell 18 is connected to the vertical pipe 13, the lower surface of the circular shell 18 is provided with an adsorption hole, the circular shell 18 is located on the inner side of the annular blade 4, the inner bottom surface of the air cylinder 16 is fixedly connected to the vertical rod 19, the vertical rod 19 passes through the piston 17, and is slidably connected to the piston 17. When cutting, when the fixed seat 3 descends , pull the vertical tube 13 and the piston 17 down, the piston 17 squeezes the gas in the cylinder 16, the gas enters the vertical tube 13 through the air hole, and is ejected through the adsorption holes on the lower surface of the circular shell 18. Before cutting, the surface of the cloth is cleaned by the air flow to avoid residual thread ends. After the cutting is completed, the lower surface of the circular shell 18 is in contact with the cloth. When the fixing seat 3 rises and resets, the piston 17 is pushed upward through the vertical tube 13, and the gas enters the cylinder 16 through the adsorption holes. The circular shell 18 adsorbs the cloth through the adsorption holes, so that the cut cloth is separated from the long cloth. When the annular blade 4 is reset, the movement stops, the air flow disappears, and the cut cloth loses adsorption and falls, which is convenient for cloth separation and removal.

[0026] like Figure 4As shown, the upper surface of the air cylinder 16 is fixedly connected to the servo motor 20, and the main shaft of the servo motor 20 is fixedly connected to the threaded rod 21. The threaded rod 21 passes through the piston 17 and is threadedly connected to the piston 17. In the process of cutting the cloth, it is necessary to first start the servo motor 20 to drive the threaded rod 21 to rotate. As the threaded rod 21 rotates, the piston 17 is controlled to descend, thereby pushing the annular blade 4 downward through the vertical tube 13 to achieve cutting of the cloth. After the cutting is completed, the servo motor 20 is started again to drive the threaded rod 21 to rotate in the opposite direction, thereby controlling the piston 17 to reset and return to its initial state. The cutting mechanism controlled by the servo motor 20 not only improves the cutting accuracy and efficiency, but also greatly improves the convenience of operation, making the cloth cutting operation easier.

[0027] like Figure 1 As shown, both sides of the fixing seat 3 are fixedly connected to the mounting bracket 22, and the rotating rollers 23 are rotatably installed on the two mounting brackets 22. The two rotating rollers 23 are used to reel in the mask fabric and release the mask fabric. When the fabric slides over the support plate 2, the fabric can be cut, and the mask fabric can be conveniently moved to change the cutting position.

[0028] Working principle: One of the two rotating rollers 23 reels the mask fabric, and the other releases the mask fabric. When the fabric slides over the support plate 2, the servo motor 20 is started to drive the threaded rod 21 to rotate. As the threaded rod 21 rotates, the control piston 17 is lowered, thereby pushing the annular blade 4 downward through the vertical pipe 13. The piston 17 squeezes the gas in the air cylinder 16, and the gas enters the vertical pipe 13 through the air hole and is ejected through the adsorption hole on the lower surface of the circular shell 18. The annular blade 4 will move downward, and its inner side is in close contact with the outer side of the cutting table 14. The serrated part of the annular blade 4 will pass through the fabric and extend into the gap between the cutting table 14 and the mounting groove. After the cutting is completed, the servo motor 20 is started again to drive the threaded rod 21 to rotate in the opposite direction, thereby controlling the piston 17 to reset. The piston 17 moves upward, and the gas enters the air cylinder 16 through the adsorption hole. The circular shell 18 adsorbs the fabric through the adsorption hole, so that the cut fabric is separated from the long fabric.
