Description

Technical Field

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

[0002] The performance of textile fabrics needs to be tested during the production process. Different types of textile fabrics have different wear resistance properties. Therefore, the wear resistance of textile fabrics needs to be tested during production and processing.

[0003] For example, Chinese patent publication number CN113109193B discloses a device and method for detecting the resistance of textile fabrics to pet scratching. The device detects the fabric by simulating the scratching method of pets, solving the problem of the lack of methods for detecting the resistance of products to pet scratching in the field of household textiles, and filling the gap in the detection technology of the resistance of household textiles to pet scratching and damage at home and abroad.

[0004] However, the device does not simulate the force exerted by a pet when scratching. It simply adjusts the angle and pressure, and relies on the motor-driven axis to drive the movement of the fabric, making the detection device completely passive in detecting the force applied to the fabric. It lacks simulation of how a pet actively exerts force to damage the fabric. The force exerted by a pet is also one of the important factors affecting the performance testing of fabrics. Therefore, the test results may not be objective enough, which will further limit the detection range. Summary of the invention

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0032] See also Figures 1 to 8 The present invention provides a technical solution: a textile fabric detection device, comprising a base 1, and further comprising:

[0033] A bracket 2 fixed on the top of the base 1;

[0034] A rotating arm is rotatably mounted on the bracket 2, and a fingertip 8 is mounted at the end of the rotating arm;

[0035] A fixing component mounted on the base 1 for fixing the sample fabric 21, and the fixing component is located below the fingertip 8;

[0036] The driving assembly is used to drive the rotating arm to swing back and forth, and the swinging speed is accelerated when swinging downward.

[0037] When the textile fabric detection device is used, the sample fabric 21 is fixed on the base 1 through the fixing component, and the fingertip 8 is installed at the end of the rotating wall, and then the driving component is used to drive the rotating arm to swing back and forth, so that the fingertip 8 scratches the sample fabric 21, so as to simulate the scratching and damage of a pet to perform detection, thereby achieving an objective and accurate detection effect;

[0038] Moreover, the swing speed of the driving component will increase when it swings downward, thereby simulating the effect of a pet applying force when scratching, thereby making the scratching detection effect more realistic and the detection result more objective and accurate.

[0039] In one of the more preferred embodiments, the rotating arm includes a ring 4 rotatably mounted on the top of the bracket 2, and a fixed tube 5 is fixed to the curved outer wall of the ring 4, a telescopic rod 6 is slidably mounted on the inner wall of the fixed tube 5, and a spring 15 is connected between the telescopic rod 6 and the inner cavity wall of the fixed tube 5, and a mounting block 7 is fixed to one end of the telescopic rod 6 extending out of the fixed tube 5, and a fingertip 8 is mounted in the mounting block 7.

[0040] The driving assembly drives the fixed tube 5 to swing back and forth, thereby driving the telescopic rod 6 and the mounting block 7 to rotate together, so that the fingertip 8 can scratch the sample fabric 21 during the rotation process.

[0041] In one of the more preferred embodiments, a fixed disk 3 is fixed on the top of the bracket 2, and a ring 4 is rotatably sleeved on the outer ring of the fixed disk 3. An arc groove 17 is provided on the inner ring of the ring 4 that contacts the fixed disk 3. A pull rope 16 is fixed to the outer wall of the fixed disk 3 located in the arc groove 17. One end of the pull rope 16 is wrapped around the fixed disk 3 and penetrates into the cavity of the fixed tube 5 and is fixedly connected to the telescopic rod 6. When the fixed tube 5 swings downward, the pull rope 16 will be wrapped around the fixed disk 3.

[0042] In this embodiment, when the fixed tube 5 is driven by the driving assembly to swing downward, it will drive the collar 4 to rotate together. Figure 5Since one end of the pull rope 16 is fixed on the fixed disk 3, the pull rope 16 will be wound on the fixed disk 3 as the ring 4 rotates. At the same time, the pull rope 16 pulls the telescopic rod 6 back, so that the mounting block 7 and the fingertip 8 at the end thereof are pulled back while swinging. Through this action, the action of a pet, such as a cat or a dog, scratching the cloth can be further imitated, so that the detection method is closer to reality and the detection result is more objective and accurate.

[0043] Then, when the fixed tube 5 swings upward, the telescopic rod 6 is extended and reset again under the elastic force of the spring 15, so that the effect of a pet scratching the cloth can be simulated by the continuous reciprocating swing of the fixed tube 5, such as the continuous digging action of a pet dog's front paws, thereby achieving a detection purpose that is closer to reality.

[0044] In one of the more preferred embodiments, the driving assembly includes a rotatable disc 12 mounted on the top of the bracket 2 through an axle seat, a pin block 13 is fixed to the outer wall of the disc 12 away from the center of the circle, a slide groove 14 is provided on the outer wall of the fixed tube 5 close to the disc 12, and the pin block 13 is inserted into the slide groove 14 and slidably connected thereto.

[0045] When the driving assembly is in use, the disc 12 is driven to rotate counterclockwise through the external structure, such as Figure 1 As shown by the middle arrow, the disc 12 will then drive the pin block 13 to rotate together, and under the sliding cooperation between the disc 12 and the slide slot 14, the purpose of driving the fixed pipe 5 to swing back and forth is achieved;

[0046] During this swinging process, as the pin block 13 rotates and drives the fixed tube 5 to swing downward, its relative position with the center of the circle of the ring 4 will decrease. Therefore, under the premise that the disc 12 rotates at a constant speed, the fixed tube 5 will accelerate when swinging downward, which can further simulate the pet's force application method, thereby making the detection result more objective and accurate.

[0047] In one of the more preferred embodiments, an inner groove is formed on the outer wall of the mounting block 7, and a round block 18 is rotatably mounted in the inner groove, and a torsion spring is installed between the round block 18 and the inner groove, a rotating rod 9 is fixed to the outer wall of the round block 18, and a slot for inserting the fingertip 8 is integrally formed on the outer wall of the round block 18, and the fingertip 8 is fixed in the slot by bolts, and a sliding sleeve 11 is slidably mounted on the outer wall of the telescopic rod 6, and a connecting rod 10 is rotatably connected between the sliding sleeve 11 and the rotating rod 9.

[0048] In the initial position, due to the torsion force of the torsion spring on the round block 18, the rotating rod 9 is attached to the inner wall of the groove in the mounting block 7, which can limit the round block 18 and the rotating rod 9. In addition, under the connection of the connecting rod 10, the sliding sleeve 11 can also limit the position. At the same time, when the telescopic rod 6 is swinging back, the fingertip 8 may touch the sample fabric 21, and the setting of the torsion spring can prevent the fingertip 8 from being deflected, so that the fingertip 8 can maintain the state every time it is scratched.

[0049] As can be seen from the previous content, the telescopic rod 6 will shrink as the fixed tube 5 swings. When it shrinks until the sliding sleeve 11 contacts the fixed tube 5, when the telescopic rod 6 continues to shrink, the fixed tube 5 will push the sliding sleeve 11 to move toward the mounting block 7. Under the action of the connecting rod 10 and the rotating rod 9, the round block 18 will be driven to rotate, and the fingertip 8 will rotate back to hook. The purpose of this is to imitate the scratching action of pets such as cats. Because some pet cats will scratch back with their claws during the scratching process, such as the cat's stepping on milk, or the action similar to scratching a cat scratching board, the fixed tube 5 will also drive the fingertip 8 to scratch back in the middle of the hem, so that the detection method is closer to reality, and the detection result is more accurate and objective.

[0050] In one of the more preferred embodiments, the fixing assembly includes a fixing bar 19 fixed to the top of the base 1, and both sides of the fixing bar 19 are set to be arc-shaped. The outer walls on both sides of the fixing bar 19 are rotatably installed with arc covers 20, and the rotation points of the two arc covers 20 are both located between the two arc centers. Screws 22 that can press and fix the arc covers 20 on the fixing bar 19 are installed at the rotation points of the arc covers 20.

[0051] For details on the fixed components, please refer to Figure 1 and Figure 5 When fixing the sample fabric 21, loosen the screws 22. At this time, the arc cover 20 can be rotated at will. Turn it upward, and then prevent the sample fabric 21 between it and the fixing bar 19, and rotate the arc cover 20 outward. Since the rotation points of the two arc covers 20 are both between the centers of the two arcs, when the arc cover 20 rotates outward, the distance between it and the arc surfaces on both sides of the fixing bar 19 will gradually decrease until the sample fabric 21 is clamped and fixed. Then tighten the screws 22 to press and fix the arc cover 20, and the fixing process of the sample fabric 21 is completed.

[0052] It is worth noting that during this process, the two arc-shaped covers 20 will first press the sample fabric 21 when rotating, and then have a pulling effect when continuing to rotate, thereby pulling the sample fabric 21 straight to prevent local wrinkles from affecting the test results.

[0053] In one of the more preferred embodiments, the inner wall of the arc-shaped cover 20 is provided with anti-skid patterns, and the provision of the anti-skid patterns can prevent the sample fabric 21 from falling off when being scratched.

[0054] In one of the more preferred embodiments, the tip portion of the fingertip 8 is configured to be pointed, convex or barbed.

[0055] For details, please refer to Figure 7 The fingertip 8 can be changed into different shapes, so that different degrees of scratching can be detected.

[0056] In one of the more preferred embodiments, a roller for supporting and guiding the pull rope 16 is installed on the inner wall of the arc groove 17. The purpose of the roller is to reduce the wear of the pull rope 16 during the pulling process, and it can also play a guiding role.

[0057] In one of the more preferred embodiments, the disk 12 is provided with an adjustment groove 23 along the radial direction, a slider 24 is slidably installed in the adjustment groove 23, and the pin block 13 is fixed on the slider 24, a threaded rod 25 is rotatably installed in the adjustment groove 23, the threaded rod 25 passes through the slider 24, and is threadedly connected to the penetration point of the slider 24.

[0058] For details, please refer to Figure 8 , by rotating the threaded rod 25, the slider 24 is driven to slide and adjust in the adjusting groove 23 under the action of the threaded cooperation with the slider 24, so as to adjust the distance between the slider 24 and the pin block 13 and the center of the disk 12. As can be seen from the previous content, the rotation of the disk 12 drives the fixed tube 5 to swing back and forth through the sliding cooperation between the pin block 13 and the slide groove 14. Therefore, when the adjusting slider 24 and the pin block 13 are closer to the center of the disk 12, the reciprocating swing angle of the fixed tube 5 will also become smaller, and vice versa. The angle of the fixed tube 5 will also be larger. In this way, the swing angle of the fixed tube 5 can be controlled by adjusting the position of the slider 24, so that the size of the scratching action of pets of different sizes can be simulated, and then targeted detection can be carried out according to the fabrics used in different positions, and the detection range is wider.

[0059] It is worth mentioning that, as the pin block 13 is closer to the center of the disk 12, the pin block 13 will be further away from the center of the swing of the fixed tube 5, that is, the center of the ring 4. In this way, when the fixed tube 5 swings downward under the drive of the pin block 13, the degree of change in its speed will become smaller accordingly, that is, the peak value of the downward swing speed of the fixed tube 5 will decrease, that is, the corresponding force action will be reduced, which is in line with the force generation method of small pets, and further adapted to the above-mentioned scratching detection for pets of different sizes.

[0060] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and the drawings can also be directly processed according to the existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0061] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
