Description

Technical Field

[0001] The invention relates to the technical field of textile machinery component performance testing, and in particular to a textile machinery component performance testing device and method. Background Art

[0002] Textile machinery components are the parts used to manufacture or maintain textile machinery. These components can be individual parts or more complex subsystems that work together to complete various tasks in the textile process, such as spinning, weaving, cutting, etc. Among the components that complete the cutting task in the textile process, there are Figure 3 A movable blade assembly is shown, which consists of a blade and a connecting handle. The blade and the connecting handle are connected by screws, and a mounting hole and a positioning rod are respectively provided on the end of the connecting handle away from the blade.

[0003] In order to ensure that the moving blade assembly can cut the cloth efficiently, it is necessary to test the sharpness of the moving blade assembly. The actual way to test the sharpness of the moving blade is to position and install the moving blade assembly through an installation device, and then drive the installation device and the moving blade assembly to rotate through external power, and use the moving blade assembly to cut the cloth, so as to evaluate the sharpness of the moving blade assembly through the shape of the incision.

[0004] Although the above method for testing the sharpness of the movable blade assembly can make the test result closer to reality by simulating the cutting method in actual use, since the blade and the connecting handle of the movable blade assembly are installed through a nut, if the nut is not installed properly during the installation process, the blade and the connecting handle will become loose, thereby affecting the cutting efficiency of the movable blade assembly. In addition, if the connection between the blade and the connecting handle is unstable, the result of the sharpness test of the blade will also be biased. In the above test process, the stability of the connection between the blade and the connecting handle cannot be directly tested, and an additional test of the stability of the connection between the blade and the connecting handle is required, which is time-consuming, labor-intensive and makes The testing process is cumbersome; in addition, the cloth used for testing the sharpness of the moving blade assembly is taken as a whole piece, and during the cutting process, the position of the cloth needs to be changed in the subsequent testing process, and the method of changing the position of the cloth by repeated disassembly and assembly or adjusting the position of the cloth installation structure is relatively cumbersome; in addition, in the working environment of the moving blade assembly, the moving blade assembly may cut the cloth obliquely or cut wrinkled cloth. The above technical solution can only test the cutting ability of the moving blade assembly on the cloth in a straight state, and cannot test the ability of the moving blade assembly to cut the cloth obliquely or cut wrinkled cloth, which makes the test single.

Then, the two-way cylinder is controlled to drive the two clamping elements to move in the same direction. At this time, the wrinkling element will wrinkle the cloth for sharpness testing.

[0033] The embodiments of the present invention are described in detail below. The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. If no specific techniques or conditions are specified in the embodiments, the techniques or conditions described in the literature in the art or the product specifications are used.

[0034] See also Figure 1 and Figure 2 A textile machinery component performance testing device comprises an L-shaped mounting plate 1, a motor No. 11 is mounted on the front side of the vertical section of the L-shaped mounting plate 1 through a motor box, a mounting unit 2 is arranged at the output end of the motor No. 11, and a pushing unit 3, a movable testing unit 4 and a fixed testing unit 5 are arranged in sequence from right to left on the front side of the vertical section of the L-shaped mounting plate 1 and at a circumferential position with the output end of the motor No. 11 as the center.

[0035] The present invention performs a sharpness test on the moving blade assembly by combining a mobile test unit 4 and a fixed test unit 5, thereby testing whether the sharpness of the moving blade assembly meets the working requirements, and the sharpness of the moving blade assembly is tested by the mobile test unit 4 and the fixed test unit 5 in a longitudinal movement manner and a wrinkle of the cloth used for sharpness testing, respectively, so that the testing method is closer to the actual working environment of the moving blade assembly, and the test result is more practical.

[0036] Specifically, the movable blade assembly is first installed through the installation unit 2, and then two pieces of cloth for sharpness testing are installed on the mobile test unit 4 and the fixed test unit 5 in turn. After the installation of the cloth for sharpness testing is completed, the No. 1 motor 11 is controlled to drive the installation unit 2 and the movable blade assembly to rotate counterclockwise, and the movable blade assembly will first be pressed against the pushing unit 3 and the pushing unit 3 will test the installation stability of the movable blade assembly itself. Then, the movable blade assembly will contact the cloth for sharpness testing at the positions of the mobile test unit 4 and the fixed test unit 5 in turn, and whether the sharpness of the movable blade assembly meets the working requirements is tested by whether the movable blade assembly can cut the cloth for sharpness testing.

[0037] See also Figure 2 and Figure 3 The mounting unit 2 includes a longitudinal axis 21 fixed to the output end of the No. 1 motor 11, a positioning column 211 is fixed to the top of the longitudinal section of the L-shaped mounting plate 1, the longitudinal axis 21 passes through the positioning column 211 and rotates with it, and a mounting handle 212 for mounting the textile machinery component is fixed on the longitudinal axis 21; a matching hole 213 and a positioning hole 214 are provided at one end of the mounting handle 212 away from the longitudinal axis 21, and the matching hole 213 is closer to the longitudinal axis 21 than the positioning hole 214, and the textile machinery component is stably mounted by the combination of the matching hole 213 and the positioning hole 214.

[0038] The mounting unit 2 is used to install the movable blade assembly, so as to facilitate the rotation of the movable blade assembly and test its sharpness. At the same time, the movable blade assembly is installed by combining the matching hole 213 and the positioning hole 214, which can ensure the stable installation of the movable blade assembly, thereby ensuring the effectiveness and accuracy of the test of the pushing unit 3. Specifically, the movable blade assembly is first aligned with the matching hole 213 through its mounting hole away from the tool position, and then a positioning pin is set between the mounting hole and the matching hole 213, and then the positioning pin is inserted and matched with the positioning hole 214 and the positioning rod on the movable blade assembly for installation, so that the installed movable blade assembly and the mounting handle 212 are stably connected.

[0039] See also Figure 2 and Figure 4The pushing unit 3 includes an L-shaped fixing rod 31 fixed to the front side of the vertical section of the L-shaped mounting plate 1. The L-shaped fixing rod 31 is arranged obliquely and a longitudinal connecting plate 311 is fixed to the bottom end of the vertical section. The bottom of the longitudinal connecting plate 311 is staggered front and back and connected to a pushing block 312 through an elastic telescopic rod. The pushing unit 3 is used to test the installation stability of the textile machinery assembly itself. Since the blade and the connecting handle of the moving blade assembly are installed through a nut, if the nut is not installed in place during its installation, the blade and the connecting handle will loosen, thereby affecting the cutting efficiency of the moving blade assembly. The pushing block 312 contacts the side of the blade. During the rotation of the mounting handle 212, the blade is continuously pushed forward and backward by the elastic telescopic rod in cooperation with the pushing block 312, thereby testing whether it is stably installed with the connecting handle.

[0040] Specifically, after the movable blade assembly is stably mounted on the mounting handle 212, the No. 1 motor 11 is controlled to drive the mounting unit 2 and the movable blade assembly to rotate counterclockwise, and the blade of the movable blade assembly will rotate counterclockwise along with the longitudinal axis 21 and the mounting handle 212. When the blade of the movable blade assembly rotates to the position of the pushing unit 3, the pushing block 312 will push the blade of the movable blade assembly, thereby testing whether the connection between the blade and the connecting handle is stable by observing whether the blade shakes. If the connection is unstable, stop the rotation of the No. 1 motor 11 and check and further stabilize the connection position between the blade and the connecting handle. Subsequently, the movable blade assembly with the blade and the connecting handle stabilized is installed again and tested again until the stability test of the movable blade assembly meets the requirements, and then the sharpness test of the subsequent movable blade assembly is carried out.

[0041] See also Figure 5 and Figure 6 The mobile test unit 4 includes a longitudinal rod 41 fixed to the front side of the vertical section of the L-shaped mounting plate 1, a longitudinal plate 411 is slidably sleeved on the longitudinal rod 41, a bending connecting rod 412 is symmetrically connected between the longitudinal plate 411 and the side of the fixed test unit 5, and a longitudinal moving element 42 for testing the sharpness of the textile machinery components is arranged at the bottom of the longitudinal plate 411; the longitudinal moving element 42 includes a slide rail 421 fixed to the bottom of the longitudinal plate 411, a U-shaped clamping plate 422 is fixed on the slide rail 421 through an electric slider, a bidirectional threaded column 423 is rotatably installed between the two vertical sections of the U-shaped clamping plate 422, a No. 2 motor 424 is installed on the right side of the right vertical section of the U-shaped clamping plate 422 through a motor sleeve, and the output end of the No. 2 motor 424 is connected to the bidirectional threaded column 423, and an inner clamping plate 425 is threadedly connected to the two threaded sections of the bidirectional threaded column 423, and a horizontal rod 426 that passes through the inner clamping plate 425 is fixed between the two vertical sections of the U-shaped clamping plate 422.

[0042] The mobile testing unit 4 is used to install the cloth for sharpness testing and drive it to move back and forth longitudinally, so that when the movable blade assembly contacts the cloth for sharpness testing, the sharpness of the movable blade assembly is tested in a manner that the cloth for sharpness testing moving in a direction perpendicular to the movable blade assembly is cut by the movable blade assembly, and this testing method can be closer to the scene of beveling the cloth in the actual working environment of the movable blade assembly, thereby making the test more practical.

[0043] Specifically, before controlling the No. 1 motor 11 to drive the mounting unit 2 and the movable blade assembly to rotate counterclockwise, the operator first takes the cloth for sharpness testing and places its two ends respectively between each inner clamping plate 425 and the vertical section of the adjacent U-shaped clamping plate 422, and then controls the No. 2 motor 424 to drive the bidirectional threaded column 423 to rotate, and makes the two inner clamping plates 425 move outward at the same time and cooperate with the vertical section of the U-shaped clamping plate 422 to clamp the two ends of the cloth for sharpness testing, and after clamping is completed, the cloth for sharpness testing is in a straight state.

[0044] After controlling the No. 1 motor 11 to drive the mounting unit 2 and the moving blade assembly to rotate counterclockwise, the moving blade assembly first moves to the position of the pushing unit 3, and the pushing unit 3 will test the stability of the moving blade assembly itself by pushing, and then the moving blade assembly will move to the position of the moving test unit 4. At this time, the electric slider is controlled to drive the U-shaped clamping plate 422 to move back and forth longitudinally. When the blade of the moving blade assembly contacts the cloth for sharpness testing, the blade of the moving blade assembly will only contact the middle position of the cloth for sharpness testing. If the sharpness of the blade meets the working requirements, a continuous incision will be left in the middle position of the cloth for sharpness testing. If the sharpness of the blade does not meet the working requirements, intermittent incisions will appear in the middle position of the cloth for sharpness testing, thereby evaluating the sharpness of the blade of the moving blade assembly according to the cutting shape of the middle position of the cloth for sharpness testing installed on the moving test unit 4.

[0045] See also Figure 5-Figure 8The fixed test unit 5 includes a limiting structure arranged on the front side of the vertical section of the L-shaped mounting plate 1, the limiting structure includes a limiting rod 51 fixed on the front side of the vertical section of the L-shaped mounting plate 1, the limiting rod 51 and the collecting plate 511 are slidably connected, the collecting plate 511 is set to be lower on the left and higher on the right, and a longitudinal spring is connected between it and the vertical section of the L-shaped mounting plate 1, and rear extension rods 512 are fixed on the rear side of the collecting plate 511 and on both sides of the limiting rod 51, and the two rear extension rods 512 both slide through the vertical section of the L-shaped mounting plate 1, and a two-way cylinder 513 is installed on the top of the collecting plate 511, and the two pushing ends of the two-way cylinder 513 are installed with clamping elements 52 for installing cloth for sharpness testing, and the front and rear sides of the collecting plate 511 are provided with folding elements 53 driven by the clamping elements 52, and the front and rear sides of the collecting plate 511 and the L-shaped mounting plate 1 are jointly provided with movable locking elements 54, and the positions of the movable locking elements 54 and the folding elements 53 are staggered with each other.

[0046] The fixed test unit 5 clamps the cloth for sharpness test by the clamping element 52, and makes the cloth for sharpness test in a wrinkled state by the folding element 53, so as to test the cutting effect of the blade of the moving blade assembly on the cloth for sharpness test in the wrinkled state, which is closer to the scene of cutting different forms of cloth in the actual working environment of the moving blade assembly, so that the test result has more practical significance.

[0047] Specifically, before controlling the No. 1 motor 11 to drive the mounting unit 2 and the movable blade assembly to rotate counterclockwise, the operator takes the cloth for sharpness testing and places its two ends at the positions of the two clamping elements 52 respectively, and then controls the clamping elements 52 to clamp the two ends of the cloth for sharpness testing, and then controls the folding element 53 to clamp the front and rear sides of the cloth for sharpness testing. After the clamping is completed, the bidirectional cylinder 513 is controlled to drive the two clamping elements 52 to move toward each other, and drives the folding element 53 to fold the cloth for sharpness testing through the clamping element 52.

[0048] In this embodiment, if Fig.10 As shown in the figure, the wrinkled part is the cloth for sharpness test. After the cloth for sharpness test is wrinkled by the wrinkling element 53, the cloth for sharpness test becomes wrinkled, and the wrinkled cloth for sharpness test appears corrugated, and the trough is the part where the cloth for sharpness test contacts with the moving blade assembly.

[0049] When the motor 11 to be controlled drives the mounting unit 2 and the moving blade assembly to rotate counterclockwise, the moving blade assembly will finally move to the position of the fixed test unit 5, and the blade of the moving blade assembly will contact the trough part of the cloth used for the sharpness test of the wrinkles. If the blade of the moving blade assembly can cut off each trough part in the middle position of the cloth used for the sharpness test, it indicates that the blade sharpness of the moving blade assembly meets the working requirements. If the blade of the blade assembly fails to cut off each trough part in the middle position of the cloth used for the sharpness test, it indicates that the blade sharpness of the moving blade assembly does not meet the working requirements.

[0050] See also Figure 7 , Figure 8 and Fig.10 The clamping element 52 includes a limit slider 521 fixed to the push end of the bidirectional cylinder 513.

A fixed clamping plate 523 is fixed to the bottom of the sides of the two clamping sleeves 522 close to each other. A mobile clamping structure is arranged in each clamping sleeve 522. The opposite sides of the two clamping sleeves 522 are hinged. The mounting frame 524 and the hinged positions on the sides of the mounting frame 524 and the clamping sleeve 522 are both provided with torsion springs (not shown in the figure) for maintaining the mounting frame 524 in close contact with the fixed clamping plate 523, and a limiting roller 525 is rotatably installed on the mounting frame 524; the movable clamping structure includes a movable clamping plate 526 slidably connected in the clamping sleeve 522, and the opposite back surfaces of the two clamping sleeves 522 are both threadedly connected with adjustment studs 527, and each adjustment stud 527 is rotatably connected to the movable clamping plate 526 at the corresponding position.

[0051] The fixed clamping plate 523 in the clamping element 52 cooperates with the movable clamping plate 526 to clamp the cloth for sharpness test, and the limiting roller 525 can adaptively tighten the installed cloth for sharpness test, thereby ensuring that the cloth for sharpness test is in a tightened state and is in contact with the blade of the movable blade assembly. Specifically, after the operator takes the cloth for sharpness test and places its two ends at the two positions of the clamping element 52 respectively, the movable clamping plate 526 is moved by rotating the adjusting stud 527 and cooperates with the fixed clamping plate 523 to clamp the two ends of the cloth for sharpness test, and the limiting roller 525 is used to make the cloth for sharpness test in a straight state after clamping.

[0053] The creasing element 53 is used to creasing the installed cloth for sharpness test, so that the test is closer to the scene of cutting cloth of different forms in the actual working environment of the movable blade assembly, and the creasing of the creasing element 53 can be synchronously driven by the movement of the two clamping elements 52 through the transmission structure, so as to realize automatic and rapid creasing, and in conjunction with the limiting roller 525, the cloth for sharpness test can be always in a straight state during the process of clamping and creasing the upper clamping plate 536 and the lower clamping plate 537.

[0054] In this embodiment, if Figure 6 , Figure 7 and Figure 8 As shown, the reset structure includes an L-shaped upper extension plate fixed on the top of the collecting plate 511 and located on the upper side of the moving rod 532, a reset spring is connected between the longitudinal section of the front L-shaped upper extension plate and the corresponding top of the moving rod 532, and a spring rod is connected between the longitudinal sections of the two rear L-shaped upper extension plates and the corresponding top of the moving rod 532, and the moving rod 532 is reset by the reset spring and the spring rod, the front transmission structure includes a pressure rod 538 fixed on the left side of the moving rod 532, and a bent pressure rod for pressing the pressure rod 538 is fixed on the front side of the left clamping sleeve 522, and the rear transmission structure includes a lifting rod 539 fixed on the right side of the moving rod 532 on the right rear side, and a bent lifting rod for lifting the lifted rod 539 is fixed on the rear side of the right clamping sleeve 522.

[0055] Specifically, when the movable clamping plate 526 cooperates with the fixed clamping plate 523 to clamp the two ends of the cloth for sharpness testing, the cloth for sharpness testing is just located between the upper clamping plate 536 and the lower clamping plate 537, and then the threaded rod 535 is controlled to adjust the position of the slide plate 534, so that the front and rear sides of the cloth for sharpness testing are stably clamped in multiple places by the upper clamping plate 536 and the lower clamping plate 537. After the clamping is completed, the two-way cylinder 513 is controlled to drive the two clamping elements 52 to move toward each other. At this time, due to the movement of the two clamping elements 52 towards each other, the bending pressure rod and the bending lifting rod on the clamping sleeve 522 press and lift the pressure rod 538 and the lifting rod 539 respectively, so that the upper clamping plate 536 and the lower clamping plate 537 on the front side move downward, and the upper clamping plate 536 and the lower clamping plate 537 on the rear side move upward, and then cooperate with the limiting roller 525 to make the cloth for sharpness testing in a wrinkled state.

[0056] See 3. Figure 7 , Figure 8 and Fig. 9 The movable locking element 54 includes a mounting strip 541 fixed to the left side of the front side of the collecting plate 511, and a plurality of trapezoidal push blocks 542 are evenly fixed longitudinally at the bottom of the mounting strip 541; an L-shaped push rod 543 is fixed at the front end of the longitudinal axis 21 for cooperating with the trapezoidal push blocks 542 to push the collecting plate 511 backward; a positioning sleeve 544 is fixed to the rear side of the top of the collecting plate 511, and a pressure block 545 is connected to the positioning sleeve 544 through a spring rod; a front extension rod 546 corresponding to the position of the pressure block 545 is fixed to the front side of the vertical section of the L-shaped mounting plate 1, and a pressing block 547 for pressing the pressure block 545 downward is fixed to the bottom of the front extension rod 546.

[0057] The movable locking element 54 is used to drive the collecting plate 511 to move backward as the movable blade assembly rotates, thereby simultaneously changing the contact position of the two pieces of sharpness test cloths with the movable blade assembly through the backward movement of the collecting plate 511, thereby increasing the utilization rate of the sharpness test cloths, and reducing the operation of replacing the sharpness test cloths, making the test more convenient, and being able to perform multiple tests on a single movable blade assembly by testing at different positions, thereby avoiding accidental test results through multiple sets of test data.

[0058] Specifically, when the movable blade assembly completes cutting of the cloth for sharpness test installed on the fixed test unit 5, the movable blade assembly will rotate to the bottom of the movable locking element 54, and then the L-shaped pushing rod 543 will first push the trapezoidal pushing block 542 on the rear side to move the assembly plate 511 backward. As the assembly plate 511 moves backward, the positioning sleeve 544 and the pressure block 545 will move backward together, and the pressure block 545 will be pressed by the frontmost pressure block 547 and move downward. When the pressure block 545 moves to the rear side of the pressure block 547, the pressure block 545 will be separated from the pressure of the pressure block 547 and move downward. Under the action of the spring rod, it returns to its original position. At this time, the L-shaped pushing rod 543 is separated from the trapezoidal pushing block 542 on the rearmost side, and the collecting plate 511 is driven by the longitudinal spring to drive the pressure block 545 to move forward. However, the front side of the pressure block 545 is blocked by the rear side of the frontmost pressure block 545, so that the position of the collecting plate 511 is fixed after the overall backward movement is completed. With the rotation of the L-shaped pushing rod 543, the L-shaped pushing rod 543 will push the trapezoidal pushing block 542 from back to front in sequence, and repeat the above actions, thereby changing the contact position between the cloth used for sharpness testing and the movable blade assembly.

[0059] After the entire cloth for the sharpness test has been used and the pressure block 545 has moved to the rear of the pressing block 547 at the rearmost side, the cloth for the sharpness test needs to be replaced. At this time, by pressing down the pressure block 545 so that it is not in contact with the pressing block 547, the entire assembly plate 511 will return to its original position due to the elastic force of the longitudinal spring and the cloth for the sharpness test will be replaced.

[0060] In addition, the present invention also provides a method for testing the performance of textile machinery components, and the specific testing method steps are as follows: S1. First, the movable blade assembly is installed through the installation handle 212. After the installation is completed, two pieces of cloth for sharpness testing are respectively installed on the clamping element 52 and the longitudinal moving element 42, and then the folding element 53 is controlled to clamp the front and rear sides of the cloth for sharpness testing. After the clamping is completed, the bidirectional cylinder 513 is controlled to drive the two clamping elements 52 to move toward each other, and the folding element 53 is driven by the clamping element 52 to fold the cloth for sharpness testing.

[0061] S2. After the cloth for sharpness test is folded, the first motor 11 is controlled to drive the longitudinal axis 21 to rotate, and the movable blade assembly will rotate together with the mounting handle 212 and the longitudinal axis 21.

[0062] S3. As the movable blade assembly rotates around the longitudinal axis 21, the pushing block 312 will first push the blade of the movable blade assembly, thereby testing whether the connection between the blade and the connecting handle is stable by observing whether the blade shakes. Then the movable blade assembly will move to the position of the movable test unit 4. At this time, the electric slider is controlled to drive the U-shaped clamping plate 422 to move back and forth longitudinally. When the blade of the movable blade assembly contacts the cloth for sharpness testing, since the blade of the movable blade assembly will only contact the middle position of the cloth for sharpness testing, the sharpness of the blade of the movable blade assembly can be evaluated according to the incision shape in the middle position of the cloth for sharpness testing.

[0063] If the sharpness of the blade meets the working requirements, a continuous cut will be left in the middle of the cloth used for sharpness testing. If the sharpness of the blade does not meet the working requirements, intermittent cuts will appear in the middle of the cloth used for sharpness testing.

[0064] S4. When the movable blade assembly is rotated to the position of the two clamping elements 52, the blade of the movable blade assembly will contact the trough portion of the wrinkled cloth for sharpness testing. If the blade of the movable blade assembly can cut each trough portion in the middle position of the cloth for sharpness testing, it indicates that the sharpness of the blade of the movable blade assembly meets the working requirements. If the blade of the blade assembly fails to cut each trough portion in the middle position of the cloth for sharpness testing, it indicates that the sharpness of the blade of the movable blade assembly does not meet the working requirements.

[0065] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations on the present invention. A person skilled in the art may make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention and they are still covered by the protection scope of the present invention.
