Description

TECHNICAL FIELD

[0002] As the core raw material of the textile industry, the quality of textile yarn directly affects the strength, appearance and durability of the final fabric. In the yarn production process, the diameter uniformity, hair index and wear resistance of the yarn are usually detected. Among them, the wear resistance is an important indicator for evaluating the anti-friction ability of the yarn in actual use, which directly affects the service life of the textile and the quality of the finished product. Therefore, the wear resistance detection of the yarn is very important.

[0003] At present, the common yarn wear resistance detection equipment is usually composed of a main body frame, a friction component, a sample clamping component, and a weight loading component. When detecting the wear resistance of the yarn, the operator first places the yarn sample on the yarn fixing device, the yarn fixing device fixes one end of the yarn and arranges the yarn horizontally, then applies tension to the other end of the yarn through the weight loading device, then installs the abrasive on the grinding roller of the friction component, and finally starts the grinding roller of the friction component to reciprocatingly rub the yarn in a rotating manner. When the yarn breaks, the wear resistance of the yarn is evaluated according to the number of rubbings recorded by the counting sensor.

[0004] The existing problems in the detection of the wear resistance of the yarn are as follows: 1. Since multiple groups of yarn samples need to be detected, the operator needs to manually reinstall a new yarn sample when one yarn sample breaks, which reduces the detection efficiency of the yarn; in addition, the existing equipment uses a single abrasive to continuously rub the yarn, and the operator needs to replace the abrasive when detecting the wear resistance of the yarn, so as to test the wear resistance of the yarn in different friction environments, which further reduces the detection efficiency of the yarn sample.

[0032] Referring to Figure 2 , Figure 3 and Figure 4 , the joint adjustment mechanism 4 comprises an adjustment cylinder 41 rotatably installed on the front end of the middle part of the mounting plate 21, the adjustment cylinder 41 is connected with the grinding roller 22 through a gear set 42, the elastic adjustment column 39 is installed on the rotating piece 33, the telescopic section of the elastic adjustment column 39 extends into the inside of the adjustment cylinder 41, and the telescopic section of the elastic adjustment column 39 is fixedly installed with the plug-in block 30 matched with the adjustment cylinder 41; when the rotating piece 33 drives the pressing rod 36 to rotate from the left side to the right side, the pushing plate 38 and the pressing rod 36 cooperate to make the corresponding clamping piece 35 always rigidly clamp the yarn, and at the same time, the rotating piece 33 drives the grinding roller 22 to rotate by a certain angle through the cooperation of the plug-in block 30 and the adjustment cylinder 41, thereby realizing the synchronous adjustment of the working surface of the grinding roller 22 to adapt to the yarn wear resistance detection requirements; the joint adjustment mechanism 4 can automatically replace the working surface of the grinding roller 22 when the traction mechanism 3 feeds the new yarn sample, so as to test the wear resistance of the yarn in different friction environments, thereby further increasing the detection efficiency of the yarn sample.

[0033] Specifically, when the wear resistance of the yarn needs to be detected, the operator puts the yarn head end wound on the bobbin through the tensioner 5 into the left clamping piece 35, the left clamping piece 35 can elastically clamp the yarn, and the operator sticks the yarn on the upper side of the left support column 34.

[0034] When the yarn needs to be fed, first start the electric sliding block assembly 31 to move the support column 34 as a whole to the front of the grinding roller 22 and the guide rod 24 through the sliding plate 32, then start the rotating part 33 to drive the two support columns 34 to rotate 180 degrees, when the left clamping part 35 starts to rotate and drives the corresponding pressing rod 36 to rotate to the corresponding position of the push plate 38, the pressing rod 36 and the push plate 38 cooperate to make the left clamping part 35 start to rigidly clamp the yarn head end, so that the clamping part 35 can pull the yarn head end, and the yarn is always in a straight state under the action of the tensioner 5, when the left clamping part 35 rotates to the right side position, it still rigidly clamps the yarn at this time, and the other clamping part 35 moves to the left side position, which can automatically clamp the yarn at the corresponding position, and the yarn is automatically attached to the upper sides of the two support columns 34 under the straightening action of the tensioner 5, ensuring that the yarn is arranged horizontally left and right, finally control the electric sliding block assembly 31 to move the yarn (i.e. the yarn sample) between the two clamping parts 35 backward to the lower side of the two guide rods 24, complete the feeding of the yarn sample, control the tensioner 5 to apply a certain tension to the yarn sample, start the reciprocating motor to drive the mounting plate 21 to reciprocate, the mounting plate 21 drives the grinding roller 22 to reciprocate for wear resistance performance detection of the yarn sample, when the yarn sample is worn and broken, the wear resistance performance of the yarn sample is evaluated according to the friction times recorded by the external counting sensor, through repeating the above steps, the feeding of new yarn sample and the wear resistance detection are realized, finally the wear resistance performance of a plurality of groups of yarn samples is comprehensively evaluated, so as to test the wear resistance performance of the yarn.

[0035] When the sliding plate 32 moves forward by a distance, at this time the insert block 30 and the adjusting cylinder 41 cooperate, when the rotating part 33 is started, the rotating part 33 drives the elastic adjusting column 39 to rotate based on its own central axis, the elastic adjusting column 39 drives the adjusting cylinder 41 to rotate by a certain angle, the adjusting cylinder 41 drives the grinding roller 22 to rotate based on its own central axis through the gear set 42, so as to realize the automatic replacement of the working surface of the grinding roller 22 (i.e. the upper side of the grinding roller 22); it needs to be noted that the forward movement distance of the electric sliding block assembly 31 through the sliding plate 32 to drive the support column 34 is realized through the precise control of the electric sliding block assembly 31 after the precise calculation of the person skilled in the art, the specific control mode is prior art, which is not repeated here.

[0036] Referring to Figure 2 and Figure 3The rotating member 33 comprises a rotating shaft 331 penetrating and rotatingly installed on the sliding plate 32, the front end of the rotating shaft 331 is connected with a driving motor 332 fixedly installed on the sliding plate 32, the rear end of the rotating shaft 331 is fixedly installed with a rotating frame 333, and the rotating frame 333 is rotationally connected with the supporting column 34; the driving motor 332 is started to drive the rotating frame 333 to rotate 180 degrees with the central axis of the rotating shaft 331 as a reference, the rotating frame 333 drives the two supporting columns 34 to synchronously rotate, so that the left supporting column 34 rotates to the right side position and the right supporting column 34 rotates to the left side position.

[0037] In order to ensure automatic feeding of the yarn sample and ensure that the yarn sample is horizontally arranged left and right, the yarn is positioned and clamped by the clamping member 35, so that the yarn sample after feeding is horizontally arranged left and right under the positioning action of the two clamping members 35, thereby ensuring the accuracy of the wear resistance detection result of the yarn. Figure 2 、 Figure 5 and Figure 6 The clamping member 35 comprises a plurality of fixed rings 351 uniformly arranged in front and back and fixedly sleeved outside the rear end of the supporting column 34, a pressing block 352 is slidingly sleeved outside the fixed ring 351 and between two adjacent fixed rings 351, a plurality of pressing springs 353 are connected between the front end of the pressing block 352 and the corresponding fixed ring 351, and the rear end of the pressing block 352 is provided in a circular table structure; the pressing rod 36 is slidingly installed in a circular groove pre-set in the inside of the supporting column 34 through the top extension spring 361, a plurality of through grooves 341 are formed in the outside of the supporting column 34 and correspond to the positions of the pressing block 352, a pressing block 342 and a square block 343 are slidingly arranged in the through groove 341, the pressing block 342 is fixedly installed outside the pressing rod 36, the square block 343 is fixedly installed inside the pressing block 352, and the rear end left side of the pushing plate 38 is provided with an inclined surface matched with the pressing rod 36; the front end of the pressing rod 36 is provided in a semispherical shape.

[0038] Specifically, after the yarn head end wound on the bobbin passes through the tensioner 5, the operator manually presses the yarn downward and adheres it to the upper side of the left supporting column 34, in this process, the yarn moves to between the pressing block 352 and the fixed ring 351 behind the pressing block 352 through the circular table structure of the pressing block 352, and under the action of the pressing spring 353, the pressing block 352 elastically presses the yarn to the front end of the fixed ring 351 behind it, so as to realize the positioning and elastic clamping of the yarn, when the left supporting column 34 drives the corresponding pressing rod 36 to rotate to the right, the front end of the pressing rod 36 moves backward and compresses the top extension spring 361 under the pushing of the inclined surface of the pushing plate 38, the pressing rod 36 drives the pressing block 342 to move backward and rigidly abuts against the front end of the square block 343, so that the pressing block 352 and the fixed ring 351 behind it rigidly clamp the yarn and pull the yarn.

[0039] When the right support column 34 rotates to the left, its corresponding pressing rod 36 and pushing plate 38 are separated and return to the initial position under the action of the extension spring 361, so that when it moves to the left position, the straightened yarn can move to the space between the pressing block 352 and the fixed ring 351 behind it through the round table structure of the pressing block 352, and adhere to the upper side of the support column 34, so as to reposition and elastically clamp the yarn.

[0040] In order to realize the rapid replacement of the working surface of the grinding roller 22 and ensure the stability of the yarn wear resistance detection of the grinding roller 22, the present application adopts the following structure: referring to Figure 2 、 Figure 3 and Figure 4 , the square frame 321 is fixedly installed on the sliding plate 32, and the rear end of the fixed section of the elastic adjusting column 39 penetrates through the rear end of the square frame 321 and is fixedly connected with the square frame 321; the connecting shaft 334 is fixedly installed at the middle part of the rear end of the rotating frame 333, the driving gear 335 is keyed connected to the outer side of the connecting shaft 334, the driven gear 391 is keyed connected to the front end of the outer side of the fixed section of the elastic adjusting column 39, and the driving gear 335 and the driven gear 391 are engaged, and the cross hole matched with the plug block 30 is opened at the front end of the adjusting cylinder 41; a plurality of circumferentially uniformly arranged elastic locking rods 411 are slidingly installed at the front end of the adjusting cylinder 41, and a plurality of circumferentially uniformly arranged locking holes are opened at the front end of the mounting plate 21, when the elastic adjusting column 39 moves backward, the rear end of the fixed section of the elastic adjusting column 39 can push the elastic locking rod 411 backward, so that the elastic locking rod 411 is inserted into the locking hole to lock the adjusting cylinder 41; a plurality of circumferentially uniformly arranged friction lining plates 221 are detachably installed on the outer side of the grinding roller 22, and the gear set 42 includes the gear ring 421 fixedly sleeved on the outer side of the adjusting cylinder 41, and the gear ring 421 and the transmission gear 422 keyed connected to the outer side of the two grinding rollers 22 are engaged.

[0041] Specifically, when the sliding plate 32 is located at the initial position, the rear end of the telescopic section of the elastic adjusting column 39 abuts against the front end of the mounting plate 21 and is in a compressed state; when the sliding plate 32 moves the elastic adjusting column 39 forward through the square frame 321, the telescopic section of the elastic adjusting column 39 extends backward under the elastic action; when the telescopic section of the elastic adjusting column 39 is fully extended, it drives the insertion block 30 to move forward and insert into the cross hole; when the rotating frame 333 rotates, the rotating frame 333 drives the elastic adjusting column 39 to rotate around its own central axis through the connecting shaft 334, the driving gear 335 and the driven gear 391; the elastic adjusting column 39 drives the adjusting cylinder 41 to rotate through the insertion block 30 and the cross hole, so that the adjusting cylinder 41 drives the grinding roller 22 to rotate around its central axis by a certain angle through the gear ring 421 and the transmission gear 422; the grinding roller 22 drives the friction lining plate 221 to rotate, so that different friction lining plates 221 detect the wear resistance of the yarn; when the sliding plate 32 moves backward to the initial position, the telescopic section of the elastic adjusting column 39 drives the insertion block 30 to move backward out of the cross hole, and the rear end of the fixed section pushes the elastic locking rod 411 backward to insert into the corresponding locking hole, thereby locking the position of the adjusting cylinder 41; thus, when the wear resistance of the yarn is detected, the mounting plate 21, the grinding roller 22 and the adjusting cylinder 41 are in a relatively static state.

[0042] In order to realize rapid adjustment of the tension applied to the yarn and ensure that the yarn is in a straightened state during the feeding process, the application adopts the following structure: the tensioner 5 comprises a U-shaped frame 51 fixedly installed on the left side of the upper end of the square frame 321, a square plate 52 fixedly installed on the top wall of the U-shaped frame 51, a plurality of square holes uniformly arranged front and rear on the square plate 52, a square sliding frame 54 slidably installed in the square holes through a pressing piece 53, a support block 55 fixedly installed on the inner walls of the front and rear of the sliding frame 54, an annular groove with a triangular cross section formed on the outer side of the support block 55, an arc-shaped clamping block 57 slidably installed on the upper end of the sliding frame 54 through a plurality of elastic downward pressing rods 56, and the lower end of the arc-shaped clamping block 57 abutting against the annular groove.

[0043] Specifically, when the yarn abrasion resistance needs to be detected, the operator pushes the arc-shaped clamping block 57 upward, and passes the yarn head end wound on the bobbin through the upper side of the annular groove of the supporting block 55, then releases the arc-shaped clamping block 57, and the arc-shaped clamping block 57 elastically clamps the yarn in the middle of the annular groove under the action of the elastic lower pressing rod 56. When the yarn is pulled, the yarn is in a straightened state under the elastic clamping action of the arc-shaped clamping block 57 and the supporting block 55. Before the yarn abrasion resistance is detected, the pressure plate 532 is driven downward by rotating the adjusting screw 533, and the sliding frame 54 is driven downward by the pressure spring 531. Because there is a large contact surface between the yarn, the arc-shaped clamping block 57 and the supporting block 55, the arc-shaped clamping block 57 elastically and stably clamps the yarn in the middle of the annular groove under the action of the elastic lower pressing rod 56, so that the arc-shaped clamping block 57 and the supporting block 55 stably apply a certain tension to the yarn downward, so that the tension applied during the rapid abrasion detection of the yarn can be adjusted by controlling the compression amount of the pressure spring 531.

[0044] It should be noted that the arc-shaped clamping block 57 and the supporting block 55 are made of rubber material, so that the arc-shaped clamping block 57 and the supporting block 55 stably clamp the yarn, and at the same time, the arc-shaped clamping block 57 and the supporting block 55 do not abrade the yarn when the yarn is pulled, ensuring the accuracy of the subsequent yarn abrasion resistance detection result.

[0045] It needs to be particularly pointed out that the prior art can also be manually loaded with yarn and abrasive replacement, that is, when a yarn sample is broken, the operator manually removes the broken yarn residue, adjusts the level of the new yarn sample fixed on the clamping device, and then starts the detection after manually disassembling and replacing the old abrasive on the grinding roller 22; although the "manual loading + manual abrasive replacement" scheme is easier to implement in technology and has lower initial cost, it only solves the surface of the basic demand of "yarn wear resistance detection" and can only complete the detection action. This method has obvious defects: each time the yarn is broken, the detection process needs to be interrupted, manual loading not only takes time (including fixing, leveling, and applying tension), but also accumulates a lot of waiting time when multiple groups are detected, resulting in low overall detection efficiency; at the same time, when manually replacing the abrasive, the machine needs to be stopped, which increases the additional process time; but in the technical scheme of the present application, the clamping piece 35 is driven by the rotating piece 33 to rotate at a fixed angle (180 degrees), which can automatically pull the new yarn sample after the yarn is broken, without the need for manual intervention to complete the loading, avoiding the interruption time of manual loading, making the detection process continuous, improving the detection efficiency of the yarn wear resistance, and by driving the grinding roller 22 to rotate synchronously, different friction linings 221 are switched to the working position, the whole process is synchronized with the loading action, without the need for additional downtime steps, which solves the complexity of manually replacing the abrasive and ensures the continuity of the detection of different friction environments, and the stability of the grinding roller 22 during operation is ensured by the cooperation of the elastic locking rod 411 and the locking hole, which improves the reliability of the detection result; the tensioner 5 can quickly and accurately adjust and stably apply the required tension of the yarn, providing a guarantee for the accuracy of the detection result; at the same time, compared with the existing yarn wear resistance detection equipment, the present scheme adds a traction mechanism 3, a linkage mechanism 4, and a tensioner 5, etc. Mechanical structure, but all are conventional ordinary mechanical structure parts, there are no high-cost precision parts, only one-time investment can be used for a long time, so the cost of the above-mentioned structure is low, and the cost of the added structure is much lower than the economic benefits brought by the improvement of detection efficiency and the reliability of the result; in summary, the above technical scheme of the present application is a specific improvement based on the above-mentioned prior art and solves the technical problems.
