Technical Field

[0001] The present invention relates to the technical field of heald detection, in particular to a device for detecting the mechanical properties of a heald eyelet. Background Art

[0002] After the heald is produced, a tensile testing machine is usually used to test the maximum tensile force when the heald breaks, and a friction testing machine is used to test the wear resistance of the heald surface. However, during the actual use of the heald, the yarn is passed through the heald eyelet and the yarn is adjusted through the heald eyelet. During the actual textile process, the yarn will constantly rub against the heald eyelet. If the mechanical properties of the heald eyelet of the produced heald do not meet the standards, the heald will wear or break prematurely during actual use, thereby affecting the quality of the textile and production efficiency.

[0003] The testing equipment in the existing technology is unable to simulate the textile environment to test the mechanical properties of the heddle eyelet, resulting in the inability to fully evaluate the wear resistance and mechanical properties of the yarn under continuous friction between the heddle eyelet. Summary of the Invention

[0004] The present application provides a device for detecting the mechanical properties of a heald eyelet, which can conveniently simulate a textile environment to detect the mechanical properties of the heald eyelet.

[0005] The present application provides a device for testing the mechanical properties of a heald eyelet, which adopts the following technical solution: Material toggling mechanism, its both ends are connected with the up-down knob.The tool holder is equipped with a set of fixedly earmarked plates, which are provided with a circle, and the two end chair assemblies are connected with each other to form a circle. The two end chair assemblies are connected with each other to form a circle.

[0006] By adopting the above technical solution, when testing the eye of the heald, the heald is clamped on the loading plate, and the detection line for simulating the yarn is passed through the eye of the heald so that the detection line contacts the inner wall of the eye, and the two ends of the detection line are respectively connected to the end faces of the two circular plates. When testing the mechanical properties of the eye, the driving mechanism drives the lead screw to rotate, so that the loading plate drives the heald to move in the vertical direction, so that the detection line can rub against the inner wall of the eye, simulating the friction between the yarn and the inner wall of the eye in a textile environment, and realizing the detection of the mechanical properties of the eye.

[0007] Preferably, the driving mechanism includes a motor; the motor is mounted on the outer wall of the column, and the output end of the motor is coaxially fixed with a driving shaft extending into the first slide groove; a first bevel gear is coaxially fixed on the outer wall of the end of the driving shaft; a second bevel gear meshing with the first bevel gear is coaxially fixed on the outer wall of the screw rod close to the first bevel gear.

[0008] By adopting the above technical solution, the starting motor drives the drive shaft and the first bevel gear to rotate. Under the engagement of the first bevel gear and the second bevel gear, the drive shaft can drive the screw to rotate, so that the loading plate drives the heald to move in the vertical direction and rub against the detection line.

[0009] Preferably, a clearance hole and a pair of threaded through holes are provided on the loading plate; the pair of threaded through holes are respectively located outside the clearance hole on both sides, and threaded rods are threadedly connected on the inner walls of the two threaded through holes; and pressure plates are fixed to the outer walls of the top ends of the two threaded rods.

[0010] By adopting the above technical solution, the heald is placed flat on the loading plate, so that the heald eye is located in the clearance hole to facilitate the insertion of the detection line, and then the threaded rods at the two threaded through holes are rotated so that the pressure plates on the two threaded rods are respectively pressed at both ends of the heald to fix the heald, so that the loading plate drives the heald to move in the vertical direction.

[0011] Preferably, a rubber pad is fixed to the bottom surface of the pressing plate.

[0012] By adopting the above technical solution, the provision of the rubber pad can increase the friction between the bottom surface of the pressure plate and the contact part of the heald, thereby improving the clamping effect of the pressure plate on the heald. At the same time, the rubber pad can protect the heald and reduce the possibility of damage to the heald.

[0013] Preferably, the circular plate is rotatably connected to the connecting plate via a rotating shaft, and a first electric push rod is installed on the end face of the circular plate close to the loading plate; the output end of the first electric push rod is fixedly connected to a slide that slides with the circular plate; the end face of the slide close to the loading plate is fixedly connected to a hanging ring; the two ends of the detection line can be respectively connected to the hanging rings on the end faces of the two slides; a pair of transmission components are provided on the outer wall of the screw rod, respectively located at the two ends of the screw rod; the pair of transmission components can enable the screw rod to drive the two rotating shafts to rotate.

[0014] By adopting the above technical solution, the two ends of the detection line passing through the heddle eye are respectively connected to the hanging rings on the end faces of the two slides, and when the first electric push rods on the two circular plates are started, the slides are driven to move, so that the detection line contacts the inner wall of the heddle eye. When the screw rotates to drive the loading plate to move up and down, the screw drives the rotating shaft and the circular plate to rotate through the transmission assembly, so that the detection line rotates around the axis of the circular plate. During the rotation of the detection line around the axis of the circular plate, the first electric push rod can be used to drive the slide to move, so that the detection line can maintain good contact with the inner circumferential wall of the heddle eye for friction during the movement, so that the detection of the heddle eye is more comprehensive.

[0015] Preferably, the transmission assembly includes a first pulley, a second pulley and a belt; the first pulley is coaxially fixed to the outer wall of the end of the screw rod; the second pulley is coaxially fixed to the outer wall of the end of the rotating shaft away from the circular plate; the belt is mounted on the outside of the first pulley and the second pulley.

[0016] By adopting the above technical solution, under the cooperation of the first pulley, the second pulley and the belt, the screw can drive the rotating shaft to rotate during the rotation process, thereby realizing the transmission of kinetic energy during the rotation of the screw.

[0020] By adopting the above technical solution, when the first electric push rod drives the skateboard to move, the slider will slide along the inner wall of the second slide groove. The movement of the skateboard is guided and limited by the cooperation between the slider and the inner wall of the second slide groove, thereby improving the accuracy of the skateboard movement.

[0021] Preferably, the slide plate is fixed with a pair of straight plates on the end face where the lifting ring is located; the pair of straight plates are respectively located outside the two sides of the lifting ring, and second electric push rods are horizontally installed on the side walls of the two straight plates that are close to each other; the two second electric push rods are staggered in the vertical direction, and the output ends of the two second electric push rods are provided with tensioning wheels that can contact the detection line.

[0022] By adopting the above technical solution, after connecting the two ends of the detection line to the hanging rings of the two slides, the two second electric push rods set on the slides are started, so that the tensioning wheels at the ends of the two second electric push rods move toward each other and squeeze the detection line, causing the detection line to be in a tensioned state to improve the detection accuracy.

[0023] Preferably, a limiting groove is provided on the outer peripheral surface of the tensioning wheel.

[0024] By adopting the above technical solution, when the tensioning wheel squeezes and tensions the detection line, the detection line will contact the inner wall of the limiting groove. The provided limiting groove is used to limit the detection line, thereby reducing the possibility of the detection line sliding randomly.

[0025] In summary, this application has the following beneficial effects: 1. Clamp the heald on the loading plate, and pass the testing wire through the heald eyelet so that the testing wire contacts the inner wall of the heald eyelet. Connect the two ends of the testing wire to the end faces of two circular plates. The driving mechanism drives the lead screw to rotate, so that the loading plate drives the heald to move vertically, causing the testing wire to rub against the inner wall of the heald eyelet. This simulates the friction between the yarn and the inner wall of the heald eyelet in a textile environment and realizes the detection of the mechanical properties of the heald eyelet. 2. During the rotation of the lead screw, it drives the two circular plates to rotate through a pair of transmission components, causing the detection line to rotate around the axis of the circular plate. During the rotation of the detection line, the camera can observe the position of the detection line in real time and transmit the observation results to the controller. The controller then controls the first electric push rod to drive the slide to move, causing the detection line to move along the inner wall of the heddle eye during the rotation process, maintaining good contact with the inner wall of the heddle eye for friction, making the detection of the heddle eye more comprehensive; 3. After connecting the two ends of the detection line to the lifting rings of the two slides, start the two second electric push rods to make the tensioning wheels at the ends of the two second electric push rods move toward each other and squeeze the detection line, so that the detection line is in a tensioned state to improve the detection accuracy.

[0029] The present invention discloses a device for detecting the mechanical properties of a heald eyelet. Figure 1 and Figure 2 As shown, it includes a workbench 1, a column 2, a loading plate 3, a detection line 5 and a driving mechanism 6; the column 2 is vertically fixed to the top surface of the workbench 1, and a first sliding groove 21 arranged in the vertical direction is opened on the outer wall of one side of the column 2. A screw rod 22 is vertically rotatably connected to the inner wall of the first sliding groove 21. The loading plate 3 is horizontally sleeved on the outer wall of the screw rod 22. The loading plate 3 and the screw rod 22 are threadedly engaged. One end of the loading plate 3 is slidably engaged with the inner wall of the first sliding groove 21, and the other end of the loading plate 3 extends to the outside to clamp and fix the heald; A pair of connecting plates 23 are horizontally fixedly connected to the outer walls of both ends of the column 2 on the side where the loading plate 3 is located. The pair of connecting plates 23 are arranged on the upper and lower sides of the loading plate 3 in the vertical direction. Circular plates 4 are installed on the adjacent end faces of the two connecting plates 23. The detection line 5 vertically passes through the loading plate 3 and the heald eye of the heald. The detection line 5 contacts the inner wall of the heald eye of the heald. The two ends of the detection line 5 are respectively connected to the adjacent end faces of the two circular plates 4. The driving mechanism 6 is arranged on the column 2, and the driving mechanism 6 can drive the screw 22 to rotate.

[0030] The heald is clamped on the carrier plate 3, and the detection line 5 is passed through the carrier plate 3 and the heald eye, so that the detection line 5 contacts the inner wall of the heald eye, and the two ends of the detection line 5 are respectively connected to the end faces of the two circular plates 4. When the mechanical properties of the heald eye are tested, the driving mechanism 6 drives the screw rod 22 to rotate, so that the carrier plate 3 drives the heald to move in the vertical direction, so that the detection line 5 can rub against the inner wall of the heald eye, simulating the friction between the yarn and the inner wall of the heald eye in a textile environment, and realizing the detection of the mechanical properties of the heald eye.

[0031] like Figure 1 and Figure 2 As shown, the drive mechanism 6 includes a motor 61, a first bevel gear 62 and a second bevel gear 63. The motor 61 is horizontally mounted on the outer wall of the column 2 near the bottom end. The output end of the motor 61 is coaxially fixed with a drive shaft 611 extending into the first slide groove 21. The first bevel gear 62 is coaxially fixed to the end of the drive shaft 611 extending into the first slide groove 21. The second bevel gear 63 is coaxially fixed to the outer wall of the end of the screw rod 22 near the first bevel gear 62. The second bevel gear 63 is meshed with the first bevel gear 62.

[0032] The starting motor 61 drives the driving shaft 611 and the first bevel gear 62 to rotate. Under the meshing cooperation of the first bevel gear 62 and the second bevel gear 63, the driving shaft 611 can drive the screw rod 22 to rotate, so that the loading plate 3 drives the heald to move vertically and rub against the detection line 5.

[0033] like Figure 1 and Figure 3 As shown, a clearance hole 31 and a pair of threaded through holes 32 located on the outside of the clearance hole 31 are vertically opened on the end of the loading plate 3 extending outside the column 2. Threaded rods 33 are threadedly connected to the inner walls of the two threaded through holes 32. A circular pressure plate 34 is coaxially fixed to the outer wall of each threaded rod 33 near the top, and a rubber pad 341 is fixed to the bottom surface of each pressure plate 34.

[0034] Place the heald flat on the loading plate 3 so that the eye of the heald is located in the clearance hole 31, and then rotate the threaded rod 33 at the two threaded through holes 32 so that the pressure plates 34 on the two threaded rods 33 are respectively pressed on both ends of the heald to fix the heald, so that the loading plate 3 drives the heald to move up and down. The setting of the rubber pad 341 improves the pressing effect of the pressure plate 34 on the heald, and also protects the heald, reducing the possibility of damage to the end of the heald.

[0035] like Figure 1 、 Figure 4 and Figure 5 As shown, the two circular plates 4 are rotatably connected to the two connecting plates 23 through the rotating shaft 24. The two circular plates 4 are horizontally mounted with a first electric push rod 7 on the end surface close to the loading plate 3. The output end of the first electric push rod 7 is fixedly connected to a slide plate 71 that slides with the circular plate 4. The end surface of the slide plate 71 close to the loading plate 3 is fixedly connected with a hanging ring 72. The two ends of the detection line 5 can be respectively connected to the hanging ring 72 on the end surface of the two slide plates 71. A pair of transmission components 25 are provided at both ends of the screw rod 22. The pair of transmission components 25 are respectively located outside the top of the column 2. The top and bottom of the workbench 1, the two transmission components 25 can make the screw rod 22 drive the two rotating shafts 24 to rotate, the transmission component 25 includes a first pulley 251, a second pulley 252 and a belt 253, the first pulley 251 is coaxially fixed to the outer wall of the end of the screw rod 22, the second pulley 252 is coaxially fixed to the outer wall of the end of the rotating shaft 24 away from the circular plate 4, the belt 253 is tensioned and sleeved on the outside of the first pulley 251 and the second pulley 252, and the belt 253 makes the first pulley 251 and the second pulley 252 linked.

[0036] The two ends of the detection line 5 passing through the heddle eye are respectively connected to the hanging rings 72 on the end faces of the two slides 71, so as to facilitate the installation of the detection line 5. Under the cooperation of the first pulley 251, the second pulley 252 and the belt 253, the screw rod 22 will drive the circular plates 4 on the two connecting plates 23 to rotate during the rotation, so that the detection line 5 rotates around the axis of the circular plate 4. In the process of the detection line 5 rotating around the circular plate 4, the first electric push rod 7 can be retracted to drive the slide 71 to move, so that the detection line 5 can move along the inner wall of the heddle eye during the rotation, maintain good contact with the inner wall of the heddle eye for friction, so that the detection of the heddle eye is more comprehensive.

[0037] like Figure 1 、 Figure 3 and Figure 4 As shown, a pair of cameras 35 are provided on the loading plate 3, which are respectively located on the outside of the two sides of the clearance hole 31. The cameras 35 can observe the contact between the detection line 5 and the inner wall of the heddle eye. A controller 26 is provided on the outer wall of the column 2. The input end of the controller 26 is electrically connected to the two cameras 35, and the output end of the controller 26 is electrically connected to the first electric push rods 7 on the two circular plates 4. The controller 26 controls the operation of the two first electric push rods 7.

[0038] When the two circular plates 4 drive the detection line 5 to rotate, the camera 35 can transmit the observed results to the controller 26, and the controller 26 then controls the first electric push rod 7 to drive the slide 71 to move, so that the detection line 5 can maintain contact with the inner wall of the heddle eye for friction during the rotation process, thereby realizing automatic adjustment of the position of the detection line 5.

[0039] like Figure 2 and Figure 5 As shown, the circular plate 4 is provided with a second slide groove 41 arranged along the extension and retraction direction of the first electric push rod 7 on the end face close to the loading plate 3. The second slide groove 41 is in a dovetail shape. A slider 42 is provided in the second slide groove 41. The slider 42 is in a dovetail shape that slides with the inner wall of the second slide groove 41. The slider 42 is fixedly connected to the end face of the slide plate 71 away from the hanging ring 72.

[0040] When the first electric push rod 7 is extended and retracted to drive the slide 71 to move, the slider 42 will move along the inner wall of the second slide groove 41. The slider 42 cooperates with the inner wall of the second slide groove 41 to guide and limit the slide 71, thereby ensuring the accuracy of the movement of the slide 71.

[0041] like Figure 5 and Figure 6 As shown, the slide plate 71 is vertically fixed with a pair of straight plates 73 located on the outside of the two sides of the hanging ring 72 on the end face where the hanging ring 72 is located. Second electric push rods 74 pointing to the side where the hanging ring 72 is located are horizontally installed on the adjacent side walls of the two straight plates 73. The two second electric push rods 74 are staggered in the vertical direction. The output end of each second electric push rod 74 is rotatably connected to a tensioning wheel 75 through a concave plate. The two second electric push rods 74 can move toward each other to cause the two tensioning wheels 75 to move toward each other to squeeze the detection line 5. A limiting groove 751 is provided on the outer circumference of each tensioning wheel 75.

[0042] When the two ends of the detection line 5 are respectively connected to the hanging rings 72 on the end faces of the two slides 71, the second electric push rod 74 on the slide 71 is started to make the tensioning wheels 75 provided on the output ends of the two second electric push rods 74 move toward each other, squeezing the detection line 5 and tightening the detection line 5 to improve the detection accuracy. The limiting groove 751 provided on the outer peripheral surface of the tensioning wheel 75 can limit the detection line 5 and reduce the possibility of the detection line 5 sliding at will.

[0043] Working principle: Place the heald to be tested flat on the loading plate 3 so that the heald eye is located in the clearance hole 31 of the loading plate 3, rotate the threaded rod 33 at the two threaded through holes 32, so that the pressure plates 34 on the two threaded rods 33 are respectively pressed on the two ends of the heald to fix the heald, and then pass the detection line 5 through the heald eye so that the detection line 5 contacts the inner wall of the heald eye, and connect the two ends of the detection line 5 to the hanging rings 72 on the end faces of the two slides 71 respectively. When the mechanical properties of the heald eye are tested, start the motor 61 to drive the drive shaft 611 and the first bevel gear 62 to rotate. Under the meshing cooperation of the first bevel gear 62 and the second bevel gear 63, the drive shaft 611 drives the screw rod 22 to rotate, so that the loading plate 3 drives the heald to move vertically, so as to cause the detection line 5 to rub against the inner wall of the heald eye, simulating the performance changes of the heald eye under the friction between the yarn and the inner wall of the heald eye in a textile environment; During the rotation process, the screw rod 22 will drive the circular plates 4 on the two connecting plates 23 to rotate through a pair of transmission components 25, prompting the detection line 5 to rotate around the axis of the circular plate 4. During the rotation of the detection line 5 around the axis of the circular plate 4, the camera 35 can observe the position of the detection line 5 in real time and transmit the observation results to the controller 26. The controller 26 then controls the first electric push rod 7 to drive the slide 71 to move, prompting the detection line 5 to maintain good contact with the inner wall of the heddle eye during the movement, so that the detection line 5 and the inner wall of the heddle eye can be fully rubbed, making the detection of the heddle eye more comprehensive.

[0044] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
