Description

Technical Field

[0001] The present invention relates to the technical field of cloth testing and sampling, and in particular to a cloth testing and sampling device. Background Art

[0002] During the fabric production process, fabric quality directly impacts the performance and market competitiveness of finished garments. Therefore, rigorous fabric quality testing is crucial to ensuring garment quality. Sampling is a crucial step in fabric quality testing, and the accuracy and efficiency of sampling are directly linked to the reliability of test results.

[0003] Traditionally, fabric sampling relies primarily on manual labor, with operators using scissors or hand-cutting tools to extract samples from large sheets of fabric. This method is not only inefficient but also prone to errors. It requires long periods of concentration and is labor-intensive. Furthermore, sampling quality is significantly affected by the operator's skill level, making consistency difficult to ensure. Furthermore, manual sampling, due to the haphazard nature of the operation and the difficulty of precise positioning by the human eye, can easily lead to inaccurate sample sizes and uneven edges, compromising the accuracy and reliability of subsequent testing.

[0016] The present invention has at least the following beneficial effects: 1. The present invention has a high degree of automation. The entire sampling process, from fabric conveying, cutting sampling, and material unloading, is automatically completed by the mechanical structure and drive device, reducing manual intervention and improving sampling efficiency and accuracy. The annular cutter cuts the fabric during rotation and pressing, ensuring neat cutting edges and good sample quality. The design of the telescopic sleeve can adapt to the sampling needs of fabrics of different thicknesses.

[0017] 2. The driving mechanism of the present invention realizes the downward pressure and rotation of the sampling tool and the linkage of the action of the blanking structure and the blowing structure through the combination of components such as the rotating drum, the transmission gear, the driven gear and the transmission sleeve. One driving source can complete multiple actions, saving energy and cost, while ensuring the coordination and accuracy between the various actions. The blanking structure and the blowing structure cooperate with the valve design to effectively remove the cut sample and store the removed cloth in the storage slot, ensuring the accuracy and reliability of sampling.

[0018] 3. When the second through hole of the present invention works in conjunction with structures such as the ventilation groove, after the sampling tool completes cutting, the airflow blown out from the second through hole can act on the sample in the sampling tool, helping the sample to detach and fall into the sample storage tank. This avoids the situation where the sample needs manual intervention to be removed due to material jamming, further improves the degree of automation and efficiency of sampling, and also reduces the damage or contamination that may be caused to the sample by manual operation.

[0019] 4. The telescopic sleeve of the present invention can automatically adjust its length according to the thickness of the fabric, ensuring that the annular cutter always maintains close contact with the fabric surface, avoiding incomplete cutting or cutter damage due to uneven fabric thickness. The rotating cutting of the annular cutter cooperates with the downward movement of the telescopic sleeve to form a composite cutting mode of shearing and tearing, reducing cutting resistance, reducing the tensile deformation of fabric fibers, and improving the quality of the sampling edge.

[0020] 5. The present invention controls the circular cutting and retraction of the fabric by pushing the telescopic electric cylinder, and can cut and sample any position on the fabric. It is not limited by the traditional fabric sampling operation: using scissors or manual cutting tools to sample from the edges and corners of large fabrics. It improves sampling efficiency and reduces sampling errors. At the same time, the circular sampling method achieved by pressing is not only simple to operate and has low labor intensity, but also can effectively guarantee the sampling quality. It does not require the operator to have a high level of skills to easily achieve fabric sampling work, and can also ensure the consistency of the sample shape and cutting edge incision. It does not require the operator to concentrate for a long time, which can effectively reduce the work pressure of the sampler. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The technical solution of the present invention will be further described in detail below in conjunction with specific implementation methods.

[0024] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0025] like Figures 1-9As shown, the fabric testing and sampling device provided in this embodiment includes a feeding device 1 for conveying fabric. The feeding device 1 is composed of a slide 101, an electric slide 102, and a storage platform 103. A sampling tool 2 is disposed above the slide 101. The storage platform 103 is fixed to the upper surface of the electric slide 102, which is slidably connected to the slide 101. A support frame 104 is fixed to the side wall of the slide 101 to support the driving mechanism 3. The storage platform 103 has a storage tank 1031 and a sample storage tank 1033 defined therein. A spacer 1032 is fixed between the storage tank 1031 and the sample storage tank 1033. The storage tank 1031 has a first through hole 1034 and a second through hole 1035 defined therein. The storage platform 103 has a ventilation groove 1036 defined therein, which is connected to the first through hole 1034. First through-hole 1034 cooperates with ventilation slot 1036: When sampling tool 2 cuts and samples the fabric, the connection between ventilation slot 1036 and first through-hole 1034 allows airflow into storage slot 1031 when needed. For example, in some cases, if the fabric is soft or fits tightly against storage slot 1031, it may be difficult for sampling tool 2 to completely separate and remove the sample from the fabric after cutting. In this case, the airflow introduced through second through-hole 1035 can help to move and separate the fabric, helping sampling tool 2 to more smoothly remove the sample from the fabric and improve the success rate of sampling.

[0026] It should be noted that when the second through hole 1035 works in conjunction with the ventilation groove 1036 and other structures, after the sampling cutter 2 completes cutting, the airflow from the second through hole 1035 can act on the sample, helping the sample to escape and fall into the sample storage tank 1033. This avoids the situation where manual intervention is required to remove the sample due to material jamming, further improving the automation and efficiency of sampling, and also reducing the damage or contamination that may be caused to the sample by manual operation.

[0027] In this embodiment, a drive mechanism 3 is externally mounted on the slide 101 to drive the sampling tool 2. The sampling tool 2 comprises an annular cutter 201 and a telescopic sleeve 202, which are telescopically connected. The sleeve 202 automatically adjusts its length based on the fabric thickness, ensuring that the annular cutter 201 maintains close contact with the fabric surface, preventing incomplete cutting or tool damage due to uneven fabric thickness. The rotation of the annular cutter 201, combined with the downward movement of the telescopic sleeve 202, creates a combined "shear and tear" cutting mode, reducing cutting resistance, minimizing fabric fiber stretching and deformation, and improving the quality of the sampling edge. Specifically, the driving mechanism includes a rotating drum 302, a connecting member is provided on the outside of the rotating drum 302, an abutting member 306 is provided on the connecting member and is abutted against the rotating drum 302, a transmission rod 312 is provided on the outside of the rotating drum 302 and is fixed to the upper surface of the telescopic sleeve 202, a transmission member is provided between the rotating drum 302 and the transmission rod 312, and a telescopic electric cylinder 313 is provided on the outside of the rotating drum 302 and is fixed to the connecting member; a support shaft 301 is fixed to the bottom end of the rotating drum 302 and is rotatably connected to the support frame 104, the connecting member includes a connecting shaft 303, a first connecting block 304 is fixed to the outer surface of the bottom end of the connecting shaft 303, a second connecting block 305 is fixed to one end of the first connecting block 304, the first connecting block 304 and the second connecting block 305 are arranged vertically, and the support shaft 301 passes through the support shaft 301 and the inside of the rotating drum 302. The abutment member 306 comprises an elastic telescopic rod 3061 mounted on the top of the second connecting block 305. A ball bearing 3062, which is in rolling engagement with the rotating drum 302, is rotatably mounted on one end of the elastic telescopic rod 3061. The other end of the elastic telescopic rod 3061 is fixed to the outer surface of the top of the second connecting block 305. The elastic telescopic rod 3061 provides a buffering effect, preventing the ball bearing 3062 from making hard contact with the chute, reducing the risk of wear and extending the service life of the device. A reciprocating chute 311 is provided within the rotating drum 302, which rolls with the ball bearing 3062. The reciprocating chute 311 consists of two inclined chute sections and two vertical chute sections, with the two ends of the inclined chute connecting to the two vertical chute sections. The ball 3062 of the elastic telescopic rod 3061 rolls in the reciprocating slide 311. When the rotating drum 302 is pressed down along with the connecting shaft 303, the ball 3062 generates a lateral component force in the inclined slide, driving the rotating drum 302 to rotate automatically without the need for an additional rotation drive device.

[0028] It should be noted that a third connecting block 307 is fixed to the top of the connecting shaft 303. The output end of the telescopic electric cylinder 313 is fixed to a connecting bracket fixed to the outer wall of the second connecting block 305. The transmission element includes a transmission gear 308 fixed to the outer surface of the top of the rotating drum 302. The outer portion of the transmission gear 308 meshes with a driven gear 309. A transmission sleeve 310 is fixed to the inner portion of the driven gear 309. The transmission rod 312 is spline-connected to the transmission sleeve 310. A bracket supporting the transmission sleeve 310 is fixed to the outer wall of the slide 101. The third connecting block 307 is connected to the top of the transmission rod 312 via a bearing. A single telescopic electric cylinder 313 simultaneously drives the vertical and rotational motions of the sampling tool 2, reducing the number of drive sources, the complexity of the equipment, the risk of failure, and maintenance costs. Its motion is transmitted through the series structure of the connecting shaft 303, the rotating drum 302, and the transmission rod 312, achieving a single power source driving multiple coordinated motions. The rotating cutting of the annular cutter 201 and the buffering effect of the telescopic sleeve 202 reduce damage to the fabric fibers, ensure the integrity of the sample, and improve the accuracy of subsequent tests.

[0029] In this embodiment, the exterior of the slide 101 is equipped with a blanking structure 4 and an air blowing structure 5 for use with the annular cutter 201. A valve 6 for use with the blanking structure 4 and the drive structure 3 is mounted on the inner bottom wall of the slide 101. The blanking structure 4 comprises a slider 401 disposed on the exterior of the slide 101. A mounting bracket 402 is secured to the upper surface of the slider 401. A gripper 403 for gripping the sample is secured to the exterior of the mounting bracket 402. A connecting rod 7 is hingedly connected between the slider 401 and the transmission rod 312. A mounting sleeve is provided at the top of the connecting rod 7, rotatably connected to the transmission rod 312. The slider 401 is hingedly connected to the transmission rod 312 via the connecting rod 7, enabling synchronized movement with the sampling cutter 2. After the drive mechanism 3 drives the sampling cutter 2 to complete cutting, the upward movement of the transmission rod 312 pulls the slider 401 along the guide rod 404 through the connecting rod 7, ensuring that the grabber 403 can reach the annular cutter 201 in a timely and accurate manner to grab the sample. This prevents the sample from falling or shifting due to time delays, thereby improving the sampling success rate. A guide rod 404 is fixed to the outer wall of the slide 101 and extends through the interior of the slider 401. The guide rod 404 extends through the interior of the slider 401, providing a stable guide for the movement of the slider 401, preventing it from shifting or shaking during movement. This ensures that the grabber 403 always accurately aligns with the sample, improving the stability and reliability of the unloading process. The blowing structure 5 includes a first piston cylinder 501 fixed to the outer wall of the slide 101. A piston block 502 is slidably mounted inside the first piston cylinder 501. A first abutting rod 504 extending to the outside of the first piston cylinder 501 is fixed to one side of the piston block 502. A second abutting rod 505 is fixed to the outer surface of the slider 401, which cooperates with the first abutting rod 504. A blowing tube 503 connected to the valve 6 is fixed to the outer surface of the first piston cylinder 501. When the slider 401 moves, the second abutting rod 505 on its outer surface pushes the first abutting rod 504, causing the piston block 502 to slide within the first piston cylinder 501, forcing gas into the valve 6 through the blowing tube 503. This purely mechanically triggered pneumatic system requires no additional control components, has a simple structure, and responds quickly. It can provide blowing assistance when the grabbing member 403 reaches the sample position, ensuring smooth sample detachment.

[0030] It should be noted that a fixed connecting shaft may be provided between the first abutting rod 504 and the second abutting rod 505 , or a reset elastic rod or spring may be provided on the first abutting rod 504 .

[0031] To further improve the material removal efficiency, the valve 6 includes a valve tube 601 fixed to the inner bottom wall of the slide 101. The interior of the valve tube 601 is fixedly connected to a piston tube 602 and a first air supply pipe 603. Two check valves 604 are elastically hinged inside the piston tube 602. The left and right ends of the valve tube 601 are fixedly connected to second air supply pipes 605. The two second air supply pipes 605 are respectively connected to the ventilation groove 1036 and the second through hole 1035. The exterior of the slide 101 is provided with a guide member for guiding the connecting shaft 303. The guide member includes a limit rod 10 fixedly provided on the exterior of the slide 101 and extending into the interior of the connecting shaft 303. The bottom end of the connecting shaft 303 is fixed with a buffer spring 11 surrounding the outside of the limit rod 10. The buffer spring 11 surrounds the outside of the limit rod 10 and provides a buffering effect during the reciprocating motion of the connecting shaft 303, reducing the impact of mechanical shock on the equipment and extending the service life of the drive mechanism 3 and the valve 6. The bottom ends of the buffer spring 11 and the limiting rod 10 are both fixed to the outer surface of the support frame 104. A second piston cylinder 8, used in conjunction with the drive mechanism 3, is fixed to the outer wall of the slide 101. An abutment block 9 is provided within the second piston cylinder 8, extending therefrom. A through-tube is fixedly connected between the second piston cylinder 8 and the piston tube 602. The extension and contraction of the abutment block 9 is adapted to the reciprocating distance of the connecting shaft 303. The abutment block 9 is connected to the interior of the second piston cylinder 8 via a return spring. When the slider 401 moves, the second abutment rod 505 pushes the first abutment rod 504, causing the piston block 502 to slide in the first piston cylinder 501, pressing the gas into the valve 6 through the air blowing pipe 503, and the gas enters the valve tube 601. The second piston cylinder 8 and the abutment block 9 cooperate with the reciprocating connecting shaft 303, so that the pressure in the piston tube 602 changes, causing the two check valves 604 to open and close, and then open and close the two second air supply pipes 605. Under the action of the check valve 604, the gas enters the second through hole 1035 through the second air supply pipe 605. The airflow in the second through hole 1035 can assist the annular tool 201 to separate the sample and cooperate with the grabbing piece 403 to fall into the sample storage tank 1033 for storage; when the sampling tool 2 moves down again, the pressure in the piston tube 602 changes again. At this time, the ventilation groove 1036 is opened and the second through hole 1035 is closed. The opening of the ventilation groove 1036 can achieve adsorption and fixation. Valve 6 controls the opening and closing of two check valves 604 based on pressure fluctuations within piston tube 602, enabling dynamic switching of the second gas pipeline 605. When the pressure within piston tube 602 fluctuates, the two check valves 604 automatically open or close based on the pressure, controlling the flow of gas into the second through hole 1035 or the vent groove 1036, respectively. This eliminates the need for an additional power source, reduces energy consumption, and provides precise control. By opening and closing the check valves 604, valve 6 rapidly switches between "air stripping" and "adsorption fixation."When the sampling tool 2 rises, the gas enters the second through hole 1035 to assist in removing the material; when the sampling tool 2 descends, the gas enters the ventilation groove 1036 to achieve adsorption and fixation, ensuring that the cloth is stably attached to the storage table 103 during the cutting process, thereby improving the cutting accuracy.

[0032] like Figures 1-9 As shown, the principle of the fabric testing and sampling device provided in this embodiment is as follows: the fabric is fixed in the storage slot 1031 of the storage table 103, and the electric slide 102 slides on the slide 101, driving the storage table 103 to move to a suitable position below the sampling tool 2; The telescopic electric cylinder 313 drives the connecting shaft 303 downward through the connecting frame, and the connecting shaft 303 drives the rotating drum 302 downward. At the same time, the rotating drum 302 rotates on the support shaft 301. As the balls 3062 of the elastic telescopic rod 3061 roll in the reciprocating groove 311, resistance is generated, causing the rotating drum 302 to rotate. The rotation of the rotating drum 302 drives the transmission gear 308 to rotate, which in turn drives the driven gear 309 and the transmission sleeve 310 to rotate. The transmission sleeve 310 drives the transmission rod 312 to rotate through the spline connection. The transmission rod 312 drives the telescopic sleeve 202 and the annular cutter 201 to press down and rotate. Since the annular cutter 201 is in a telescopic state, when the annular cutter 201 moves downward, the annular cutter 201 first contacts the fabric and presses the fabric tightly. The balls 3062 roll in the reciprocating groove 311, which not only generates resistance to rotate the drum 302 but also drives the annular cutter 201 to rise and fall through the transmission rod 312. During the lifting process, the annular cutter 201 slowly releases the pressure and rotates with the drum 302 to achieve cutting of the fabric. The cut sample remains in the annular cutter 201. When the sampling tool 2 rises, the connecting rod 7 drives the slider 401 to slide on the guide rod 404, and the slider 401 drives the mounting frame 402 and the grabbing member 403 to move below the annular tool 201, and the grabbing member 403 grabs the sample; When the slider 401 moves, the second abutting rod 505 pushes the first abutting rod 504, causing the piston block 502 to slide in the first piston cylinder 501, pressing the gas into the valve 6 through the air blowing pipe 503, and the gas enters the valve tube 601. The second piston cylinder 8 and the abutting block 9 cooperate with the reciprocating connection shaft 303 to change the pressure in the piston tube 602, so that the two check valves 604 are opened and closed, and then the two second air supply pipes 605 are opened and closed. Under the action of the check valves 604, the gas enters the second through hole 1035 through the second air supply pipe 605. The airflow in the second through hole 1035 can assist the annular cutter 201 to separate the sample, and cooperate with the grabbing member 403 to fall into the sample storage tank 1033 for storage; When the sampling tool 2 moves downward again, the pressure in the piston tube 602 changes again. At this time, the vent groove 1036 is opened, and the second through hole 1035 is closed. The vent groove 1036 is opened to achieve adsorption and fixation.
