Description

Technical Field

[0001] The present application relates to the field of spinning-related equipment, and in particular to a fully automatic single yarn strength machine and a single yarn testing method. Background Art

[0002] Fully automatic single yarn strength testers are used to test the breaking strength and elongation of single yarns and pure or blended yarns made of various types of cotton, wool, linen, silk, chemical fiber, and core-spun yarns. Existing single yarn strength testers on the market use upper and lower rubber rollers to drive the yarn feeding mechanism. The yarn delivery mechanism utilizes a rotary motor with an extended rocker mechanism. The upper and lower chuck mechanisms are located outside the operating panel, and the yarn suction mechanism utilizes an AC motor and a vacuum chamber.

[0003] The single yarn strength tester consists of a box, a yarn drum and a testing device. The yarn drums are rotatably connected to the inside of the box, and the yarn is wound on the drums. When testing the yarn, the yarn on the drum is pulled out and connected to the testing device, and then the yarn is tested for various values.

[0004] In the prior art, when pulling a yarn from a reel onto a testing device for testing, the yarn ends must be manually removed from the reel, then connected to the testing device, and then activated to test various yarn values. To test another reel of yarn, another reel must be manually reinstalled on the testing device. Consequently, numerical testing of different yarn types requires manual supervision, requiring the user to switch to another yarn type after testing one type, which wastes manpower. Summary of the Invention

[0005] In order to facilitate the testing of yarns and improve the testing efficiency, the present application provides a fully automatic single yarn strength tester.

[0006] This application provides a fully automatic single yarn strength machine, which adopts the following technical solutions:

[0007] A fully automatic single yarn strength tester, comprising a box and a testing device arranged on the box;

[0008] The bottom of the box is rotatably connected to a rotating disk, and the rotating disk is provided with a plurality of fixed columns at intervals along its circumferential direction. A winding drum is plugged into the fixed columns, and the winding drum can rotate relative to the fixed columns. The bottom of the box is provided with a first drive for driving the rotating disk to rotate;

[0009] The testing device includes a traction clamp and two fixing clamps, the two fixing clamps are spaced apart along the height direction of the box; the fixing clamp includes two clamping parts, and the box is provided with a second drive for driving the two clamping parts to move closer to or away from each other;

[0010] The traction clamp is provided with a suction nozzle;

[0011] The box body is provided with a traction drive, which is arranged parallel to the height direction of the box body, and drives the traction clamp to flip from the outer side of the box body to the inner side of the box body.

[0012] By adopting the above technical solution, when testing the yarn, the traction drive drives the traction clamp and the suction nozzle to move to the inside of the box, opens the traction clamp, starts the suction nozzle, and driven by the traction drive, the suction nozzle moves up and down along the height direction of the box to suck out the thread end on the winding drum, and then closes the traction clamp to clamp the thread end.

[0013] The traction drive continues to drive the traction clamp to move, driving the yarn to pass through the two fixed clamps. When the traction clamp moves to the position to be tested, the two fixed clamps fix the yarn at the same time, and the traction clamp continues to move until the yarn breaks.

[0014] The traction clamp releases the broken yarn, and the fixed clamp at the bottom opens. After the traction clamp moves to between the two fixed clamps to clamp the yarn, the fixed frame at the top opens, and the traction clamp moves down again to the test position. At this time, the two fixed clamps fix the yarn, and the traction clamp continues to move until the yarn breaks; repeat multiple times to take the average value.

[0015] After completing the test of one group of yarns, the first drive drives the rotating disk to move and rotate the next group of yarns to the testing position, and repeats the above operation to test the next group of yarns.

[0016] Through the cooperation of the testing device, the suction nozzle and the traction drive, the device does not require manual operation when clamping the thread end on the winding drum, thereby improving the automation performance of the equipment, facilitating the testing of the yarn and improving the testing efficiency.

[0017] Optionally, the first drive includes gear 1 and gear 2, both of which are rotatably connected to the box body, and gear 1 and gear 2 are engaged with each other, and the number of teeth of gear 1 is greater than the number of teeth of gear 2.

[0018] By adopting the above technical solution, after testing a roll of yarn, the first drive is started, the rotation of gear 2 drives the rotation of gear 1, and the measured yarn roll is rotated to one side. At the same time, the next yarn roll is rotated to the work station to be tested. The structure is simple and easy to control.

[0019] Optionally, the second drive includes a bidirectional screw rod 1 and two screw rod nuts 2, the bidirectional screw rod 1 is rotatably connected to the box body, the two screw rod nuts 2 are respectively threadedly connected to the two opposite threaded parts of the bidirectional screw rod 1, the clamping part is fixedly connected to the screw rod nuts 2, and the box body is provided with a sliding groove for the clamping part to slide.

[0020] By adopting the above technical solution, before the traction clamp drives the yarn through the fixed clamp, the bidirectional screw 1 rotates to drive the two screw nuts 2 away from each other, and the two clamping parts move away from each other with the two screw nuts 2. When the traction clamp moves to the test position, the bidirectional screw 1 rotates in the opposite direction to drive the two screw nuts 2 toward each other, and the two clamping parts move with the two screw nuts 2 until the two clamping parts clamp the yarn. The provision of a second drive facilitates the control of the opening and closing of the fixed clamp.

[0021] Optionally, the traction clamp includes a sliding plate and two clamping plates, the sliding plate is slidably connected to the box body, the two clamping plates are slidably connected to the sliding plate, the suction nozzle is arranged on the sliding plate, and the sliding plate is provided with a third drive for driving the two clamping plates to move closer to or away from each other.

[0022] By adopting the above technical solution, before the traction clamp clamps the yarn, the third drive drives the two clamping plates to move away from each other. When the yarn is located between the two clamping plates, the third drive drives the two clamping plates to move closer to each other until the two clamping plates fix the yarn.

[0023] Optionally, the traction drive includes a chain, a driving sprocket and a driven sprocket, the driving sprocket and the driven sprocket are both rotatably connected to the box body, the chain is engaged with the driving sprocket and the driven sprocket at the same time, and the sliding plate is fixedly connected to the chain.

[0024] By adopting the above technical solution, when the traction drive drives the traction clamp and the suction nozzle to move, the driving sprocket rotates to drive the chain to rotate, and the driven sprocket rotates accordingly. The setting of the chain makes it easy to drive the traction clamp and the suction nozzle from the outside of the box to the inside of the box.

[0025] Optionally, a thread end fixing device is provided on the inside of the box body, and the thread end fixing device includes a glue feeding head, a glue feeding hose, a driving cylinder and scissors. The driving cylinder is fixedly connected to the box body, and the glue feeding head is inserted into the driving cylinder. A piston is provided at one end of the glue feeding head located in the driving cylinder. The glue feeding head is connected to the glue feeding hose, and an air pipe is connected to the driving cylinder.

[0026] By adopting the above technical solution, after the test is completed, the scissors open, the rotating disk rotates, and the winding drum rotates to the front of the thread end fixing device. At this time, the yarn is located in the opening of the scissors; then the glue hose supplies glue to the glue head, and the glue adheres to the yarn. After a certain period of rest, when the glue dries to a slightly sticky glue block, the air pipe supplies air to the drive cylinder, driving the glue head to move outward from the drive cylinder, driving the glue block to move and adhere to the winding drum; then the scissors close to cut the yarn, and the suction nozzle is activated to recycle the cut yarn. The setting of the thread end fixing device makes it easy to fix the tested yarn on the winding drum, reducing the possibility of yarn falling off the winding drum due to the lack of fixed thread ends.

[0027] Optionally, a fan is provided on the box.

[0028] By adopting the above technical solution, setting a fan can speed up the drying of the glue and improve the working efficiency of the equipment.

[0029] Optionally, a pulley for overlapping the yarn is provided outside the box.

[0030] By adopting the above technical solution, since the traction clamp will pull the yarn on the winding drum from the inside of the box to the outside of the box, setting a pulley can reduce the friction between the yarn and the box, reduce yarn friction, and improve the accuracy of the test.

[0031] A method for testing a fully automatic single yarn strength tester comprises the following steps:

[0032] Clamping the thread end: The traction clamp clamps the thread end of the yarn on the reel;

[0033] First yarn test: The traction clamp moves downward, driving the yarn through the two fixed clamps. When the traction clamp moves to the test position, the two fixed clamps clamp the yarn at the same time. The traction clamp continues to move downward until the yarn breaks.

[0034] Test the yarn again: the traction clamp releases the broken yarn, the fixed clamp at the bottom opens, the traction clamp moves to clamp the yarn between the two fixed clamps, the fixed clamp at the top is released, the traction clamp moves down to the test position again, the two fixed clamps clamp the yarn at the same time, and the traction clamp moves until the yarn breaks;

[0035] Repeat the test on the yarn multiple times and take the average value.

[0036] In summary, this application has the following beneficial technical effects:

[0037] 1. Through the cooperation of the testing device, suction nozzle and traction drive, manual operation is not required when clamping the thread end on the yarn drum, which improves the automation performance of the equipment, facilitates yarn testing and improves testing efficiency;

[0038] 2. The setting of the fixing device makes it easy to fix the tested yarn on the yarn drum, reducing the possibility of the yarn falling off the yarn drum due to the lack of fixed thread ends. BRIEF DESCRIPTION OF THE DRAWINGS
