[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figure 1 - Figure 8As shown, the present invention provides a textile disc sampling device with adjustable size, including a shell 1, a pressure rod 3 is axially slidably connected to the middle of the shell 1, a fixed disk 4 is provided inside the shell 1, and the fixed disk 4 is fixedly sleeved on the outer wall of the pressure rod 3, a plurality of knife holders 2 are evenly arranged along the circumferential direction inside the shell 1, all of which are equipped with blades (not shown in the figure), and auxiliary fixing mechanisms 5 are provided at the bottom of all of the knife holders 2. An adjusting mechanism for adjusting the cutting radius of multiple blades is provided inside the fixed disk 4, and the adjusting mechanism includes a rotating disk 6, a plurality of rotating disks along the diameter of the shell 1, and a plurality of rotating disks. The telescopic component 7 for telescoping and the driving component 8 for driving the turntable 6 to rotate, the turntable 6 is rotatably arranged at the bottom of the fixed disk 4, and is movably sleeved with the pressure rod 3, multiple telescopic components 7 are evenly arranged on the side wall of the fixed disk 4 along the circumferential direction, and all telescopic components 7 are fixedly connected to the corresponding tool holder 2, the driving component 8 is arranged on the turntable 6, a movable groove 9 is opened inside the pressure rod 3, a support rod 10 is slidably connected inside the movable groove 9, a pressure plate 11 is fixedly connected to the bottom of the support rod 10, an elastic member 12 and a wrinkle removal mechanism for smoothing the textile fabric are provided in the movable groove 9.

[0024] The elastic member 12 includes a spring, which is disposed in the movable groove 9 , and two ends of the spring are fixedly connected to the support rod 10 and the pressure rod 3 respectively.

[0025] When the present invention is in use, the textile fabric is placed on the rubber pad, and the shell 1 is placed on the textile fabric on the rubber pad. The side of the shell 1 with a circular opening is placed on the rubber pad in a horizontal state. At this time, the pressure plate 11 first contacts the textile fabric. After gently pressing the shell 1, the pressure rod 3 is pressed downward. The pressure rod 3 drives the fixed disk 4 and the knife holder 2 to move downward until the blade cuts into the textile fabric. Then the pressure rod 3 is rotated, and the fixed disk 4 and multiple knife holders 2 outside it are driven to rotate in the circumferential direction, thereby cutting a circular sample from the textile fabric on the rubber pad, completing the sampling of the textile fabric; wherein, the adjustment mechanism is set up, and sampling of discs of different sizes can be achieved. When sampling of discs of different sizes is required, the drive assembly 8 drives the turntable 6 to rotate, the turntable 6 drives the telescopic assembly 7 to move, and the telescopic assembly 7 drives the knife holder 2 to move, thereby achieving adjustment of the cutting radius of the blade fixed on the knife holder 2.

[0026] Specifically, the telescopic assembly 7 includes a movable cylinder 71, a fixed rod 72 and two limiting protrusions 73. A plurality of sliding grooves 74 are provided on the outer wall of the fixed disk 4. The movable cylinder 71 is slidably arranged in the corresponding sliding grooves 74. One end of the fixed rod 72 is slidably connected to the movable cylinder 71, and the other end of the fixed rod 72 is fixedly connected to the outer wall of the pressure rod 3. The end of the movable cylinder 71 away from the fixed rod 72 is fixedly connected to the tool holder 2. A linear guide groove 75 is provided on the fixed disk 4, and a plurality of arc guide grooves 76 corresponding to the linear guide grooves 75 are provided on the rotating disk 6. The two limiting protrusions 73 are respectively fixed on both sides of the end of the movable cylinder 71, and the two limiting protrusions 73 are slidably connected to the linear guide groove 75 and the arc guide groove 76 respectively; When the turntable 6 rotates, the limiting protrusion 73 moves along the inside of the arc-shaped guide groove 76 and drives the movable cylinder 71 to slide and extend outside the fixed rod 72.

[0027] The driving assembly 8 includes a gear ring 81, a gear 82 and a driving motor 83. The gear ring 81 is fixedly set in the middle of the turntable 6 and is movably mounted on the pressure rod 3. The gear 82 is rotatably set on the turntable 6 and engages with the gear ring 81. The driving motor 83 is installed on the fixed disk 4, and the output shaft of the driving motor 83 passes through the fixed disk 4 and is coaxially fixed with the gear 82.

[0028] By activating the drive motor 83, the output shaft of the drive motor 83 drives the gear 82 to rotate. Since the gear 82 meshes with the ring gear 81, the rotation of the gear 82 drives the ring gear 81 to rotate accordingly, thereby driving the rotation of the turntable 6. When the turntable 6 rotates, the limiting protrusion moves along the arcuate track of the arcuate guide groove 76, thereby driving the movable cylinder 71 to reciprocate within the slide groove 74 along the direction of the linear guide groove 75. At the same time, because one end of the fixed rod 72 is slidably connected to the movable cylinder 71 and the other end is fixedly connected to the outer wall of the pressure rod 3, the movement of the movable cylinder 71 drives the blade holder 2 to slide telescopically along the outer wall of the fixed rod 72, thereby adjusting the cutting radius of the blade to different sizes.

[0029] During this process, all sampling blades on the blade holder 2 follow the telescopic movement of the movable cylinder 71, allowing the disc sampling device's blade cutting radius to be adjusted to suit different testing standards or the sampling requirements of specialized materials. Furthermore, thanks to the design of the chute 74 and linear guide groove 75, the movement path of the movable cylinder 71 is precisely controlled, making the sampling process more stable and reliable. Simultaneously, by adjusting the rotational speed and direction of the drive motor 83, the rotational speed of the turntable 6 and the movement speed of the sampling blades can be easily controlled, achieving precise control of the blade radius and significantly improving sampling efficiency.

[0030] The top of the pressure rod 3 is fixedly connected to the handle 13, and the outer wall of the handle 13 is evenly distributed with multiple arc-shaped anti-slip grooves 74. The design of the arc-shaped anti-slip grooves 74 not only increases the friction between the hand and the handle 13, allowing the user to hold the handle 13 more firmly during operation, preventing sampling deviation caused by hand slippage, but also improves the user experience. In addition, the shape and size of the handle 13 are carefully designed to ensure compliance with ergonomic principles, ensuring comfort and reducing hand fatigue even during long-term operation.

[0031] The wrinkle removal mechanism includes an air pump 91 and an air pipe 92. The air pump 91 is installed on the support rod 10, and the air pipe 92 is installed on the top of the handle 13 and is connected to the movable groove 9. An air guide groove 93 is opened inside the support rod 10, and a diversion groove 94 is opened on the inner wall of the pressure plate 11. The outer wall and bottom of the pressure plate 11 are provided with multiple air ports 95 connected to the diversion groove 94. The output end of the air pump 91 is connected to the air guide groove 93, and a one-way valve is provided at the connection between the air guide groove 93 and the pressure plate 11.

[0032] A sealing cover 96 is provided on the top of the air pipe 92 , and the sealing cover 96 is threadedly connected to the outer wall of the air pipe 92 .

[0033] When the pressure rod 3 is pressed down, the air pump 91 is started and the cover 96 at the top of the air pipe 92 is opened, allowing external air to enter the movable groove 9 through the air pipe 92. When the air pump 91 is started, the air in the movable groove 9 is transported to the air guide groove 93 by the air pump 91, and then enters the diverter groove 94 in the pressure plate 11 through the air guide groove 93, and then is evenly ejected through the air port 95, forming a stable airflow. This airflow can effectively smooth out wrinkles on the surface of the textile fabric, ensuring that the surface of the textile fabric is flat during sampling. Moreover, through the blowing of the air, the textile fabric can be spread flat on the plastic rubber pad, thereby preventing the textile fabric from sliding or shifting during the sampling process. This allows the textile fabric to be pressed and fixed and smoothed and fixed before cutting, improving the accuracy and stability of sampling. In addition, by adjusting the output power of the air pump 91, the intensity and speed of the airflow can be controlled to meet the sampling requirements of textiles of different materials and thicknesses. This not only improves sampling efficiency, but also greatly enhances the practicality and applicability of the sampling device.

[0034] Furthermore, when the pressure plate 11 contacts the textile fabric, the sealing cover 96 is threadedly fixed on the air pipe 92, thereby closing the air pipe 92. At this time, the interior of the movable groove 9 is in a sealed state. After the pressure plate 11 contacts the textile fabric, the air port 95 at its bottom is closed. Therefore, as the air pump 91 continues to work, the gas inside the movable groove 9 can be discharged from the air port 95 on the outside of the pressure plate 11. After the air pressure inside the movable groove 9 is reduced, a negative pressure is formed in the movable groove 9, so that the pressure rod 3 moves downward along the outside of the support rod 10, and drives the fixed plate 4 and the knife holder 2 to move downward synchronously until the blade on the knife holder 2 contacts the textile fabric and pierces it. At this time, the staff holds the handle 13 and drives the handle 13 to rotate, thereby driving the pressure rod 3 to rotate, realizing cutting of the textile fabric. By driving the pressure rod 3 downward by adsorption by the air pump 91, the force of manual downward pressure can be reduced, making the cutting operation easier and more labor-saving.

[0035] It is worth noting that due to the telescopic setting of the tool holder 2 and the blade, there will be a large gap between the inner wall of the shell 1 and the outer edge of the pressure plate 11. In order to prevent the blade from driving the textile fabric to move during rotation and cutting, thereby affecting the cutting quality, an auxiliary fixing mechanism 5 is provided at the bottom of all tool holders 2 to assist in fixing the textile fabric. A slot is provided at the bottom of all tool holders 2, and all auxiliary fixing mechanisms 5 are installed in the slot of the corresponding tool holder 2. The auxiliary fixing mechanism 5 includes an arc-shaped slider 51, an arc-shaped mounting frame 52, a plurality of buffer springs 53 and a plurality of rollers 54. The arc-shaped slider 51 is slidably connected to the inside of the slot of the corresponding tool holder 2. All buffer springs 53 are evenly fixed on the top of the arc-shaped slider 51, and all buffer springs 53 are fixedly connected to the inner wall of the tool holder 2. The arc-shaped mounting frame 52 is fixedly connected to the bottom of the arc-shaped slider 51, and all rollers 54 are evenly arranged at the inner bottom of the arc-shaped mounting frame 52 and are rotatably connected to the arc-shaped mounting frame 52.

[0036] When the knife holder 2 moves downward and drives the blade mounted on its side wall to move downward until it contacts the textile fabric, the roller 54 at the bottom of the knife holder 2 first contacts the surface of the textile fabric. As the knife holder 2 continues to move downward until the blade contacts the textile fabric, the roller 54 is squeezed and pushes the arc-shaped mounting frame 52 at its top to move upward, driving the arc-shaped slider 51 at the top of the arc-shaped mounting frame 52 to move upward along the inside of the slot, thereby compressing the buffer spring 53, so that the blade is fixed to the side of the textile fabric cutting position by the roller 54. The blade then continues to move downward and cuts the textile fabric below it. The knife holder 2 and the blade are rotated by rotating the pressure rod 3. At this time, the roller 54 moves synchronously with the rotation of the knife holder 2 and rolls along the surface of the textile fabric, thereby assisting in fixing the textile fabric and preventing the textile fabric from deflecting or moving during the cutting process, further ensuring the accuracy and stability of the cutting. At the same time, the setting of the roller 54 also reduces the frictional resistance between the blade and the textile fabric, making the cutting process smoother. In addition, the elastic support design of the buffer spring 53 between the roller 54 and the tool holder 2 can adapt to textile fabrics of different materials, ensuring that the roller 54 can always fit closely to the textile fabric and provide a stable fixing effect.

[0037] In addition, the bottom of the pressure plate 11 is made of a soft and elastic material, which can ensure a close fit between the pressure plate 11 and the textile fabric while preventing the textile fabric from being indented or deformed due to excessive pressure. At the same time, the edge of the pressure plate 11 is finely polished to prevent sharp edges from scratching the textile fabric, further improving the quality of sampling.

[0038] In practice, the operator simply places the textile to be sampled on the rubber pad of the sampling device, then presses down on the pressure lever 3, activates the air pump 91, and opens the cover 96 on top of the air tube 92. This completes the smoothing, fixing, and sampling of the textile fabric. The entire sampling process is fast, accurate, and stable, significantly improving sampling efficiency and quality.

[0039] An inspection opening 14 is provided on one side of the housing 1 .

[0040] The access hatch 14 facilitates easy access to the disc sampling device for maintenance and repair, ensuring proper operation. When cleaning, replacing blades, or performing other maintenance, access hatch 14 is readily available. This not only improves the device's maintainability but also extends its lifespan.
