TECHNICAL FIELD

[0001] The present application relates to the technical field of woven fabric thickness detection, and particularly relates to a knitted fabric thickness uniformity evaluation and measurement device. BACKGROUND

[0002] When the thickness tester is used to test the thickness of a fabric, a counterweight is needed. Different pressure and test area are applied to different samples, and the required counterweight is calculated according to the requirements, and the following calculation formula is obtained: .

[0003] For different materials of the fabric, different configuration weights are needed to avoid measurement errors. After the pressure foot and the elastic expansion rod of the digital display are fixed, the weight can be placed on the pressure foot to increase the pressure of the pressure foot on the sample.

[0004] Since the weight and the pressure foot are separately arranged, when the pressure foot is connected to the digital display, the worker needs to take the weight. Since the weight is certain, impurities will inevitably stick to the weight during repeated taking of the weight, which will cause a certain change in the weight of the weight, and in turn increase the error in the thickness measurement result.

[0005] Therefore, the traditional woven fabric thickness measurement device can be improved to avoid the above problems and facilitate the detection personnel to evaluate the thickness uniformity of the sample according to the measurement result. SUMMARY

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-4 The present invention provides a technical solution: A device for evaluating and measuring the thickness uniformity of knitted fabrics, comprising: The base 1 has a protruding testing platform 2 fixed on it. The base 1 also has a bracket 3 fixed on it. A rotating rod 5 is rotatably connected to the base 1. A handle 6 is fixed to the end of the rotating rod 5. The rotation of the rotating rod 5 can be easily controlled by the handle 6. The top of the rotating rod 5 is also rotatably connected to the bend of the bracket 3. The slider 7 is provided with a threaded hole 9 for connecting with the rotating rod 5, and the slider 7 is fixed with a fixed block 8. The support 3 is provided with a vertical slot 4 for slidingly connecting with the fixed block 8. When the rotating rod 5 rotates, the slider 7 moves along the support 3 in the vertical direction; The slot 10 is provided on the slider 7 and is slidingly connected with the bottom of the digital display meter 13. Until the bottom of the digital display meter 13 abuts against the slider 7, the digital display meter 13 is fixed with a connecting block 15 which is slidingly connected with the connecting slot 11. The slot 10 is threadedly connected with a screw rod 12. The rotation of the screw rod 12 causes the partial deformation of the slider 7, thereby reducing the size of the slot 10 and fixing the digital display meter 13. The bottom of the digital display meter 13 is provided with an elastic telescopic rod 14 which is threadedly connected with a screw groove 17 provided on the presser foot 16. The elastic telescopic rod 14 of the digital display meter 13 can be used to measure the thickness by checking the corresponding value on the digital display meter 13. This is a direct reference to the prior art and will not be described here. The presser foot 16 is connected with a plurality of weights 21 through a connecting piece, and the required number of weights 21 is determined by a control piece.

[0019] Specifically, as shown in Figure 1 The connecting piece includes a vertical rod 18 fixedly connected with the presser foot 16, and the vertical rod 18 is threadedly connected with a sleeve 20. The vertical rod 18 is slidingly connected with the weights 21. The upper surface of the weight 21 is provided with a corresponding slot 22, and the lower surface is fixed with a clamping block 23 matched with the corresponding slot 22. The presser foot 16 is also provided with a clamping slot 19 matched with the clamping block 23. By rotating the sleeve 20, the plurality of weights 21 can be stacked. The clamping block 23 of the upper weight 21 extends into the corresponding slot 22 of the lower weight 21. The clamping block 23 of the weight 21 on the presser foot 16 extends into the clamping slot 19. The sleeve 20 can make the plurality of weights 21 closely fit, preventing the weights 21 from sliding randomly under force on the vertical rod 18. When the sleeve 20 is separated from the vertical rod 18 during rotation, the weights 21 can be removed from the vertical rod 18, and different weights 21 with different pressures can be replaced.

[0020] Specifically, as shown in Figure 4 The control piece includes a hook slot 24 provided on the weight 21. The slider 7 is provided with a horizontal slot 25, and a round rod 26 is fixedly arranged in the horizontal slot 25. The round rod 26 is slidingly connected with a cross block 27. The cross block 27 is threadedly connected with a rotating rod 29. The bottom end of the rotating rod 29 is rotatably connected with a hook block 30 which extends into the hook slot 24. The slider 7 is also provided with a limiting piece for limiting the rotating rod 29.

[0021] The spring one 28 is sleeved on the round rod 26, one end of the spring one 28 is fixedly connected with the inner side wall of the horizontal groove 25, the other end is fixedly connected with the side wall of the horizontal block 27, and the spring one 28 pushes the horizontal block 27 to move until the hook block 30 on the horizontal block 27 extends into the hook groove 24.

[0022] Specifically, as shown in the figure, Figure 3 The limiting piece includes the cover block 31 which is slidingly connected on the rotating rod 5, the bottom of the cover block 31 is provided with the sleeve groove one 32 which is matched with the rotating rod 29, the bottom of the cover block 31 is fixedly provided with the bottom block 34, the sliding block 7 is provided with the circular groove 35 which is matched with the bottom block 34, and the rotating rod 5 is sleeved with the spring two 36.

[0023] The cover block 31 is further provided with the sleeve groove two 33, when the sleeve groove one 32 is sleeved on the top end of the rotating rod 29, the hook block 30 extends into the hook groove 24 at this time, and when the sleeve groove two 33 is sleeved on the rotating rod 29, the hook block 30 is separated from the hook groove 24.

[0024] After the cover block 31 rotates away from the rotating rod 29 and the bottom block 34 is aligned with the circular groove 35, under the elastic force of the spring two 36, the cover block 31 moves down to be attached to the sliding block 7, and the bottom block 34 extends into the circular groove 35.

[0025] As described above, the measuring device provided in the embodiment is installed: The digital display meter 13 is abutted to the upper surface of the sliding block 7, and the digital display meter 13 is slidingly connected with the slotted groove 10, the connecting block 15 on the digital display meter 13 is slidingly connected with the connecting groove 11. The screw rod 12 is rotated, so that the sliding block 7 at the slotted groove 10 is deformed, causing the size of the slotted groove 10 to be smaller, and the digital display meter 13 is clamped, that is, the connection between the digital display meter 13 and the sliding block 7 is completed.

[0026] The screw sleeve 20 is rotated, so that the screw sleeve 20 moves to the upper end of the vertical rod 18, at this time, the plurality of weights 21 on the vertical rod 18 can move in the vertical direction. Then the cover block 31 can be lifted, so that the sleeve groove two 33 is separated from the rotating rod 29, under the elastic force of the spring one 28, the horizontal block 27 moves close to the weight 21. The cover block 31 is rotated, so that the cover block 31 rotates away from the rotating rod 29, and the bottom block 34 at the bottom of the cover block 31 is aligned with the corresponding circular groove 35, under the elastic force of the spring two 36, the bottom block 34 is clamped with the circular groove 35, the cover block 31 is fixed with the sliding block 7, so that the cover block 31 at this time will not affect the subsequent thickness measurement. Until the hook block 30 extends into the hook groove 24 of the weight 21 which is attached to the presser foot 16, the rotating rod 29 is rotated, so that the rotating rod 29 moves upward, then the hook block 30 drives all the weights 21 to move upward, then the presser foot 16 is not pressed by the weight 21, until the uppermost weight 21 is abutted to the screw sleeve 20.

[0027] The screw groove 17 of the presser foot 16 is connected with the elastic telescopic rod 14 of the digital display meter 13 through screw connection. The rotating rod 5 is rotated by rotating the handle 6 until the sliding block 7 moves downward together with the digital display meter 13 until the appropriate height is reached. At this time, the presser foot 16 is in abutment with the detection table 2 under the cooperation of the elastic telescopic rod 14, and then the value of the digital display meter 13 is adjusted to zero.

[0028] During thickness measurement: The required number of weights 21 is selected according to the measured sample to determine the required pressure, and each weight 21 is marked with a weight value, and the required pressure corresponding to the number of weights 21 can be obtained by simple addition calculation.

[0029] For example, one weight 21 is required. The horizontal block 27 is pushed to move until the hook block 30 is disengaged from the hook groove 24, and the lowermost weight 21 is released, that is, the required number of weights 21 is released. Under the action of the weight, the required weight 21 falls onto the presser foot 16. The rotating rod 29 is rotated so that the rotating rod 29 and the hook block 30 move upward until the hook block 30 is aligned above the second weight 21 of the presser foot 16. The pushing force on the horizontal block 27 is released, and the horizontal block 27 and the hook block 30 move under the action of the spring 28 until the hook block 30 extends into the hook groove 24 of the second weight 21. At this time, the rotating rod 29 is reversely rotated so that the rotating rod 29 moves upward, and under the action of the hook block 30, the unnecessary weights 21 are all moved upward away from the presser foot 16.

[0030] Because the thickness of the sample moves, the presser foot 16 does not contact the unnecessary weights 21 of the hook block 30 during the extension and retraction of the elastic telescopic rod 14.

[0031] The presser foot 16 is lifted upward, the measured sample is placed on the detection table 2, the lifting force on the presser foot 16 is released, and the presser foot 16 is moved downward together with the elastic telescopic rod 14 to press the sample tightly. At this time, the detection result can be checked through the digital display meter 13.

[0032] The above description of the embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to these embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
