Description

Technical Field

[0001] The invention relates to the technical field of fabric detection, in particular to a wool fabric detection device. Background Art

[0002] Wool fabric refers to fabric made of wool fiber, which is usually derived from wool, but can also include hair from other animals, such as rabbit hair, camel hair or alpaca hair. Wool fabric is widely used in making various clothing and home textile products due to its excellent warmth retention, softness and moisture absorption. Wool fabric testing mainly includes the evaluation of its physical properties, chemical composition, appearance quality, etc. Through testing, it can be ensured that wool fabrics meet quality standards during production and use, so as to provide high-quality product performance and user experience.

[0003] Among them, the physical property test evaluates the strength, elasticity, durability and recovery ability of the fabric by applying tension, pressure and other methods. At present, most wool fabric testing devices can only test a single performance. The exchange and preparation time between devices is long, which affects the overall testing efficiency. In addition, multiple testing devices occupy a large experimental space, which is not convenient for laboratory management. It is impossible to quickly fine-tune the pulling strength of the wool fabric during the tensile test, and thus it is impossible to obtain detailed test data. The traditional wear resistance test usually fixes the wool fabric on a flat chopping board and then uses a friction head to perform rotational friction, which is not completely consistent with the force and friction conditions of the wool fabric in actual use. It is too extreme and cannot fully simulate the friction environment in actual use, resulting in the test results deviating from the actual use. Therefore, the present invention proposes a wool fabric testing device to solve the problems mentioned in the above background technology. Summary of the invention

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The detection mechanism provided in the present invention has two test functions: tensile resistance and wear resistance. The tensile resistance test of wool fabric can be performed through the pulling mechanism, and the wear resistance test of wool fabric can be performed through the friction mechanism. The bracket mechanism cooperates with the pulling mechanism to clamp the wool fabric, and can be combined with the pulling mechanism to form a friction support. In conjunction with the friction mechanism test, the device combines the two test mechanisms together, which greatly saves the process of exchanging wool fabrics between different devices and the detection time of wool fabrics, improves the detection efficiency, and integrates a device with multiple test functions, saves the investment of equipment costs, and reduces the floor space occupied by the experimental test area;

[0020] 2. The pulling mechanism provided in the present invention, after the wool fabric is laid flat on the placement plate, the pulling mechanism at the bottom cooperates with the clamping seats on the bracket mechanisms at both sides to realize automatic clamping of both sides of the wool fabric, thus saving the assembly time of the wool fabric. The cross frames at both sides are driven by the mechanism to swing back and forth, thus realizing the tensile test process of the wool fabric. The extension length of the upper strip block of the second rotating seat of the transmission structure is adjusted, and the pulling strength can be finely adjusted to meet various test requirements and enrich the tensile test results of the wool fabric.

[0021] 3. The friction mechanism provided in the present invention can combine and assemble the clamping seat on the support mechanism and the placing seat on the pulling mechanism. The two clamping seats form a V-shaped friction support for wear resistance test. Cooperating with the friction roller on the friction mechanism, the mechanism drives the relative displacement of the friction roller and the V-shaped friction support below, and simulates the real daily friction situation of wool fabrics through the rotation of the friction roller. Compared with the traditional wear resistance pilling test, this test mechanism can obtain the most realistic wear resistance pilling test situation and data of wool fabrics;

[0022] 4. The two test mechanisms on this device do not interfere with each other and can be assembled together to perform friction tests. The limit block limits the position of the pulling mechanism in the device seat. The bevel gear does not contact or interact with the lower bar block and provides a bottom support for the friction mechanism. When performing a tensile test, one side of the friction mechanism can be stored and folded, and the T-shaped seat does not interact with the lower convex ring.

[0023] In summary, this testing device integrates tensile and wear resistance testing functions, reduces the operating steps and equipment requirements, the pulling mechanism cooperates with the bracket mechanism to realize automatic clamping of wool fabric, and the pulling strength is fine-tuned by adjusting the length of the bar block to adapt to different testing needs. The friction mechanism combines the clamping seat and the placement seat into a V-shaped base to simulate the real friction situation and improve the accuracy of the test. The testing mechanisms do not interfere with each other and can switch functions as needed. The friction mechanism can be folded and stored during the tensile test to ensure flexibility and efficiency of the operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention.

The seat 410 is horizontal, and two rotating shafts 1 403 are connected to each other between the two rotating shafts 2 404. The two rotating shafts 1 403 are both connected to the lifting seat 401. A bevel gear 1 402 connected to the lifting seat 401 is provided on the lower side between the two rotating shafts 1 403, and a bevel gear 2 405 meshing with the middle bevel gear 1 402 is fixed to the inner ends of the two rotating shafts 1 403. A spur gear 406 is fixed to the outer ends of the two rotating shafts 1 403. Another spur gear 406 is fixed to one end of the two rotating shafts 2 404. The spur gears 406 on the two rotating shafts 1 403 are respectively meshed with two other spur gears 406.

[0043] Furthermore, referring to Figure 3-7 The bracket mechanism 3 includes a bracket 301, which slides forward and backward on the upper side of the device seat 1. A sliding slide 302 is arranged on the upper side of the bracket 301, and a clamping seat 303 is arranged on the upper side between the left and right slides 302. A slide groove corresponding to the slide 302 is arranged in the bracket 301, and a return spring 306 corresponding to the slide 302 is arranged in the slide groove. Slide blocks 413 are arranged at the four corners of the left and right outer sides of the lifting seat 401, and corresponding slide grooves are opened on the left and right inner sides of the device seat 1. The left and right inner sides of the device seat 1 are connected with the corresponding bracket 301. Four discs 8, the other side of the device seat 1 is connected with a limit block 7 corresponding to the two limit shafts 411. At this time, the limit block 7 is located at the lower side of the two limit shafts 411 to limit the downward movement of the entire pulling mechanism 4. The limit block 7 is a fan-shaped structure. When a tensile test is required, the wool fabric is first laid flat on the left and right placement seats 410, and the two sides of the wool fabric pass between the placement seat 410 and the outer clamp seat 303. At this time, the limit block 7 structure is rotated to rotate the fan-shaped edge outward, so that the pulling mechanism 4 loses the obstruction and can be adjusted downward;

[0044] The cam 303 of the support frame 301 is provided with a plurality of sliding blocks, each of which is provided with a plurality of sliding blocks, each of which is provided with a plurality of sliding blocks.

[0045] Furthermore, referring to Figure 5 , 6 , 9, and a lever 407 located outside the lifting seat 401 is fixed to the lower side of the bevel gear 1 402, a motor 6 is fixedly installed at the lower part of one side of the device seat 1, a rotating seat 2 9 is fixed to the front end of the output shaft of the motor 6, and a plurality of shifting blocks 91 corresponding to the lever 407 are arranged on the rotating seat 2 9, and the shifting blocks 91 slide inside and outside in the rotating seat 2 9, and a plurality of screw rods 92 corresponding to the shifting blocks 91 are transferred to the rotating seat 2 9, and a knob 93 is transferred to the center of the outer side of the rotating seat 2 9, and a bevel gear is fixed to the inner end of the knob 93, and another bevel gear meshing with it is fixed to the inner ends of the plurality of screw rods 92, and the knob 93 is used to rotate the screw rods 92. The plurality of screw rods 92 are driven to rotate, thereby adjusting the inner and outer positions of the plurality of strip blocks 91 in the rotating seat 2 9. The motor shaft drives the plurality of strip blocks 91 on the rotating seat 2 9 to rotate, thereby realizing intermittent driving of the upper bevel gear 1 402. The bevel gear 1 402 rotates, and the two rotating shafts 1 403 rotate through the meshing bevel gear 2 405. The rotating shaft 1 403 rotates the left and right outer rotating shafts 2 404 through the meshing left and right spur gears 406, thereby realizing the intermittent cross rotation of the cross frames 409 on both sides and the seats 410 thereon, and repeatedly pulling the wool fabric fixed thereon;

[0046] Furthermore, the rotation angle of the bevel gear 402 is completely determined by the rotation of the strip block 91 on the swivel seat 2 9. By adjusting the inner and outer positions of the strip block 91 in the swivel seat 2 9, the rotation angle of the bevel gear 402 can be adjusted. When the strip block 91 is adjusted inwardly to shorten, the rotation angle of the bevel gear 402 connected to the lever 407 is small. When it is adjusted outwardly, the angle of the bevel gear 402 is larger. The rotation angle of the bevel gear 402 can adjust the pulling force of the wool fabric to provide More diverse pulling conditions and choices can obtain more complete tensile test results. A limit block 408 is fixed on the lower side of the lifting seat 401, and a stopper corresponding to the limit block 408 is fixed on the lower side of the bevel gear 402. A torsion spring is provided at the transition of the bevel gear 402. The torsion spring is used for resetting the bevel gear 402 after it is turned. Following the turning of the next bar block 91, the limit block 408 and the corresponding stopper limit the rotation angle of the bevel gear 402, and keep the connected lever 407 within the interactive range of the turning of the bar block 91.

[0047] Furthermore, referring to Figure 1 , 2 7. When the wear test is required, the pulling mechanism 4 is kept located at the upper part of the device seat 1, and the limit stopper 7 is located at the lower side of the two limiting shafts 411. At this time, the lever 407 on the lower side of the pulling mechanism 4 is also not within the interactive range of the lower lever block 91, so it will not be linked to the cross frame 409 inside the pulling mechanism 4. The lower sides of the left and right ends of the clamp seat 303 are provided with slots corresponding to the slide 302. Buckle blocks 304 are fixed on the left and right sides of the outer side of the clamp seat 303. Buckle grooves 412 corresponding to the buckle blocks 304 are provided on the left and right sides of the inner side of the placement seat 410. The slide can be The clamp seat 303 in the middle of 302 is removed, and the clamp seat 303 is combined with the placement seat 410 through the buckle block 304 and the corresponding buckle groove 412. The two clamp seats 303 are assembled in the middle of the two placement seats 410 to form a V-shaped friction surface for wear resistance test. A slot of a certain thickness is set between the buckle grooves 412 on both sides. Before the clamp seat 303 and the placement seat 410 are assembled, the two sides of the wool fabric are placed on the outside of the clamp seat 303 and in its slot. When the buckle block 304 is buckled into the buckle groove 412, the clamp seat 303 and the placement seat 410 also complete the clamping of the two sides of the wool fabric.

[0048] Furthermore, referring to Figure 2 , 8The friction mechanism 5 includes a vertical seat 501, a friction roller 502 and a T-shaped seat 503. A sliding sleeve seat 504 is arranged at the lower part of the T-shaped seat 503. A sliding seat 2 is fixed to one side of the outer side of the device seat 1. The sliding sleeve seat 504 slides left and right in the sliding seat 2. The T-shaped seat 503 slides up and down in the sliding sleeve seat 504. The vertical seat 501 is transferred to one end of the upper part of the T-shaped seat 503. The upper end of the vertical seat 501 is transferred to a rotating seat 506. The friction roller 502 is transferred to the rotating seat 506. A convex ring 10 is fixed on the output shaft of the motor 6. The convex ring 10 corresponds to the upper T-shaped seat 503, and the convex ring 10 is provided with a notch. The connection between the notch and the notch is set as an inclined surface. The motor 6 drives the connected convex ring 10 to rotate. Before the rotation, the lower end of the T-shaped seat 503 is located at the notch of the convex ring 10. During the rotation of the convex ring 10 The lower end of the T-shaped seat 503 is squeezed to the outer side of the convex ring 10 through the inclined surface of the connection, and a return spring 11 corresponding to the sliding sleeve seat 504 is arranged in the sliding seat 2. When the notch of the convex ring 10 is rotated to the T-shaped seat 503 again, the sliding sleeve seat 504 and the friction mechanism 5 thereon are moved inward by the elastic force of the return spring 11. As the motor shaft drives the convex ring 10 to rotate continuously, the sliding sleeve seat 504 and the friction mechanism 5 thereon move back and forth in the V-shaped friction groove. The other end of the upper part of the T-shaped seat 503 is connected with a limiting rotating block 505 corresponding to the sliding seat 2. A small motor connected to the friction roller 502 is installed on the rotating seat 1 506, and the small motor on the rotating seat 1 506 is controlled to make the connected friction roller 502 rotate, and cooperate with the inside of the friction groove to complete the simulated friction test of the wool fabric.

[0049] Furthermore, referring to Figure 3 , 8 , and the upper end of the vertical seat 501 is connected with a limit pin 507 corresponding to the rotating seat 506. When there is no need to perform a friction test, or when a tensile test is required, the friction mechanism 5 can be stored and the linkage relationship with the lower motor 6 can be released, and the T-shaped seat 503 in the sliding sleeve seat 504 can be moved upward, and the lower end of the T-shaped seat 503 slides out of the notch position of the convex ring 10 and staggers the rotation interaction range with the convex ring 10, and then the other end of the T-shaped seat 503 is rotated to limit the rotating block 50 5, so that the lower end of the limiting rotating block 505 falls on the upper side of the slide seat 2, thereby limiting the height of the T-shaped seat 503 in the sliding sleeve seat 504, and making the upper end friction roller 502 move out of the combined V-shaped friction groove. At this time, the vertical seat 501 on the T-shaped seat 503 is rotated 180 degrees, and the friction roller 502 originally located on the upper side of the placement seat 410 is immediately moved out of the device, and the lower limit pin 507 is opened, so that the rotating seat 506 and its friction roller 502 can be rotated and stored vertically.
