Description

Technical Field

[0001] This invention relates to the field of cotton fiber testing technology, and in particular to a cotton fiber strength testing device and testing method. Background Technology

[0002] Cotton fiber strength refers to the degree to which cotton fibers resist tensile breakage. Cotton fiber strength is one of the important items in cotton quality inspection. When other indicators are basically the same, fiber strength is positively correlated with yarn and fabric quality. In modern spinning equipment with high rotation speed, high fiber strength plays an important role in reducing yarn breakage rate and improving production efficiency.

[0003] Cotton fiber strength is typically measured using specific cotton fiber strength testing tools. Current cotton fiber strength testing methods require manual sampling of cotton bales before placing them into the testing device, which reduces work efficiency. Manually inserting tools directly into the cotton bales can damage the cotton fibers inside, affecting their subsequent use. Manual sampling can only be performed on one spot within the cotton bale, leading to inaccurate cotton fiber testing and impacting the accuracy of the cotton fiber analysis. Summary of the Invention

[0004] Existing cotton fiber testing devices require manual sampling of cotton bales before placing them into the device for testing, which reduces work efficiency and can damage the cotton fibers inside the bales, affecting their subsequent use. To address the technical problem of inaccurate cotton fiber testing, this invention proposes a cotton fiber strength testing device and method.

[0005] The present invention proposes a cotton fiber strength testing device, which includes a conveyor line, a pushing component installed on the conveyor line, a rotating turntable installed on one side of the conveyor line, and a sampling device and a testing device installed on the outer surface of the rotating turntable.

[0006] The rotary table is located on one side of the conveyor line, and the rotary table drives the sampling device to rotate.

[0007] The sampling device is located on the outer surface of the rotating turntable and samples the cotton bales conveyed by the conveyor line. The sampling device includes a driving component and a sampling component. The driving component drives the sampling component to enter the cotton bales of the conveyor line, and the sampling component clamps the cotton fibers inside the cotton bales.

[0008] The detection device is located on the outer surface of the rotating turntable and performs strength testing on the cotton fibers clamped by the sampling device. The detection device includes an aggregation component and a detection component. The aggregation component wraps the sampling device, and the detection component performs strength testing on the cotton fibers clamped by the sampling component.

[0009] Preferably, the drive assembly includes a rotating frame, one end of which is fixedly mounted to one end of the output shaft of the rotating turntable. A rotating sleeve with gears is rotatably connected to one end of the rotating frame via a bearing. A rotary motor is fixedly mounted to one end of the rotating frame, and the output shaft of the rotary motor meshes with the gears of the rotating sleeve via gears. A sampling sleeve is slidably inserted into the inner wall of the rotating sleeve. A multi-stage telescopic hydraulic cylinder is fixedly mounted on the outer surface of the rotating frame. A push rod is fixedly mounted to one end of the telescopic rod of the multi-stage telescopic hydraulic cylinder. One end of the push rod is slidably inserted into the inner wall of the top end of the sampling sleeve. An electromagnetic ring is fixedly mounted to one end of the push rod, and the outer surface of the electromagnetic ring is magnetically connected to the inner wall of the top end of the sampling sleeve.

[0010] Through the above technical solution, the sampling device can be switched via the rotating frame, which facilitates faster detection of cotton bales conveyed on the conveyor line. After the rotary motor is started, it drives the rotating sleeve to rotate, and the rotation of the rotating drum drives the sampling sleeve to rotate, thus facilitating the insertion of the sampling sleeve into the cotton bale. The rotational force makes the sampling sleeve inserted into the cotton bale reduce damage to the cotton fibers. One end of the sampling sleeve is conical to reduce damage to the cotton fibers. A multi-stage telescopic hydraulic cylinder can push the sampling sleeve to move within the rotating drum, thus allowing the sampling sleeve to be inserted into the interior of the cotton bale. The electromagnetic ring is magnetically connected to the inner wall of the sampling sleeve, which facilitates control of the movement of the sampling sleeve.

[0011] Preferably, the sampling assembly includes a sampling hook, which is made of nickel-titanium alloy shape memory metal in the shape of a hook and coated with silicon dioxide material on its outer surface. The sampling hook is hinged to the inner wall of the sampling sleeve by a pin. One end of the sampling hook is hinged to a push rod by a pin. The outer surface of the push rod is rotatably connected to a rotating ring by a bearing. One end of the push rod is hinged to the outer surface of the rotating ring by a pin.

[0012] The above technical solution utilizes the deflection of sampling hooks to extract cotton fibers from within the cotton bale, enabling sampling of the cotton fibers. Multiple sampling hooks can sample from multiple locations within the cotton bale. The sampling hooks are made of nickel-titanium alloy shape memory metal, allowing them to deform under temperature influences. The overall alloy composition (e.g., increasing Ni content) is also incorporated.

[0013] Set the temperature to 50-80℃ (to avoid burning the fibers).

[0014] Preferably, the aggregation assembly includes a connecting sleeve, which is fixedly installed on the outer surface of the housing of the rotary table. A connecting frame is fixedly installed on the outer surface of the connecting sleeve. A movable block with a rod is slidably inserted into the upper surface of the connecting frame via a slide rod. A transmission rod is rotatably connected to the lower surface of the connecting frame via a bearing. A drive motor is fixedly installed on the lower surface of the connecting frame. One end of the output shaft of the drive motor drives the transmission rod to rotate via a bevel gear set. Both ends of the transmission rod are fixedly installed with turntables with arc grooves. One end of the rod of the movable block is slidably inserted into the inner wall of the arc groove on the inner side of the turntable.

[0015] Through the above technical solution, the rod of the moving block can move within the arc groove of the turntable by the rotation of the turntable. The rotation of the turntable can push the rod to rise and fall, thereby driving the moving block to rise and fall. The drive motor can drive the transmission rod to rotate.

[0016] Preferably, the outer surface of the movable block is hinged with a cover cylinder by a pin, the two cover cylinders are symmetrically distributed, the outer surface of the cover cylinder is provided with a deflection groove, the outer surface of the connecting frame is slidably inserted with a push handle, one end of the push handle is slidably inserted with the inner wall of the deflection groove, and the other end of the push handle is slidably inserted with the inner wall of the outer arc groove of the turntable.

[0017] Through the above technical solution, the lifting and lowering of the movable block can drive the cover cylinder to rise and fall, and the lifting and lowering of the push handle can be achieved by rotating the turntable, thereby moving within the deflection groove. After pushing the deflection groove to deflect, the cover cylinder is deflected, allowing the cover cylinder to open.

[0018] Preferably, the detection component includes a limiting guide rail, which is fixedly installed on the upper surface of the connecting frame. A clamping lower block is slidably inserted into the upper surface of the limiting guide rail. One end of the clamping lower block extends through the inner wall of the cover cylinder and into its interior. A rubber strip is fixedly adhered to the inner wall of the cover cylinder. The outer surface of the rubber strip contacts the outer surface of the clamping lower block. A pushing hydraulic cylinder is fixedly installed on the outer surface of one of the clamping lower blocks. One end of the piston rod of the pushing hydraulic cylinder is fixedly installed on the outer surface of the other clamping lower block.

[0019] Through the above technical solution, in order to test the strength of cotton fibers, the clamping block can be pushed by the hydraulic cylinder, thereby pulling the clamped cotton fibers to complete the strength test. The rubber strip can seal the connection between the clamping block and the cover cylinder.

[0020] Preferably, a limiting frame is fixedly installed on the outer surface of the lower clamping block, and a clamping screw is rotatably connected to the outer surface of the limiting frame via a bearing. A clamping motor is fixedly installed on the lower surface of the limiting frame, and one end of the output shaft of the clamping motor is fixedly installed to one end of the clamping screw. A clamping slider is provided on the outer surface of both the limiting frame and the clamping screw. One clamping slider is threadedly connected to the outer surface of the clamping screw, and the other clamping slider is slidably connected to the outer surface of the limiting frame. A clamping upper block with gears is hinged to the outer surface of the clamping slider via a pin. One end of the clamping upper block is slidably inserted into the inner wall of the groove of the limiting frame. A deflection rack is fixedly installed on the outer surface of the limiting frame, and the deflection rack meshes with the gear of the clamping upper block.

[0021] Through the above technical solution, in order to clamp cotton fibers, the clamping screw rotates under the drive of the clamping motor, which in turn drives the clamping slider to rise and fall. The clamping slider can then drive the clamping upper block to rise and fall. After the gear of the clamping upper block meshes with the deflection rack, it can drive the clamping upper block to deflect, thereby facilitating the pressing of cotton fibers and the entry and exit of cotton fibers into the clamping lower block.

[0022] Preferably, the outer surface of the clamping lower block is provided with a suction hole, and a suction pipe is fixedly installed on the upper surface of the connecting frame. One end of the suction pipe is located below the suction hole, and a heating and cooling component is fixedly connected to one end of the suction pipe. A fan unit is fixedly connected to one end of the heating and cooling component. The fan unit consists of two fans, one of which blows air into the suction pipe, and the other of which draws air into the suction pipe.

[0023] Through the above technical solution, the suction force generated by the suction pipe is transmitted through the suction hole, which allows the cotton fibers to be adsorbed above the suction hole and thus clamped. The heating and cooling components are made of a heater and a compression refrigeration system. The heater can heat the air transported in the suction pipe, and the compression refrigeration system can cool the air in the suction pipe.

[0024] Preferably, a bracket is fixedly installed on the outer surface of the connecting frame, a camera is fixedly installed on the lower surface of the bracket, a lifting hydraulic cylinder is fixedly installed on the outer surface of the bracket, a recovery pipe is fixedly installed at one end of the piston rod of the lifting hydraulic cylinder, one end of the recovery pipe is fixedly connected to the air inlet of the recovery fan, and after descent, one end of the recovery pipe is slidably inserted into the inner wall of the cover cylinder.

[0025] The above technical solution allows the recovery pipe to be raised and lowered by a lifting hydraulic cylinder, enabling the recovery pipe to be inserted into the cover cylinder. The cotton fibers that have been tested can then be recovered by a recovery fan.

[0026] The present invention provides a detection method for a cotton fiber strength testing device, comprising the following steps:

[0027] S1: The conveyor line transports the cotton bales that need to be tested. After reaching the set position, the hydraulic cylinder in the push assembly pushes the push plate to fix the cotton bales. After the rotary motor on the rotating frame starts, it drives the rotating sleeve to rotate. At the same time, the multi-stage telescopic hydraulic cylinder pushes the push rod to move. The push rod drives the sampling sleeve to move. The sampling sleeve moves inside the rotating sleeve. At the same time, the rotation of the rotating sleeve drives the sampling sleeve to rotate. The sampling sleeve is inserted into the cotton bale. The electromagnetic ring is de-energized, the multi-stage telescopic hydraulic cylinder retracts, and it drives the push rod to move at the top of the sampling sleeve. After the rotating ring moves, the push rod pushes the sampling hook to deflect and is located inside the cotton bale. It hooks the cotton fibers inside the cotton bale. The push rod moves under the push of the multi-stage telescopic hydraulic cylinder. The sampling hook is reset. After the electromagnetic ring is energized, it is magnetically connected to the inner wall of the sampling sleeve. After the rotating turntable starts, it drives the rotating frame to rotate. The sampling sleeve is located above the open cover cylinder.

[0028] S2: After the drive motor on the connecting frame starts, it drives the transmission rod to rotate through the transmission of the bevel gear set. The transmission rod drives the turntable to rotate. The rotation of the turntable drives the moving block to rise through the rod, and then drives the cover cylinder to rise. The continuous rotation of the turntable can drive the push handle to rise through the trajectory of the arc groove. The push handle can drive the cover cylinder to deflect relatively through the deflection groove and then close, so that the sampling sleeve is located inside the cover cylinder, and the rotating sleeve is inserted into one end of the cover cylinder.

[0029] S3: After the fan unit starts, one of the fans draws in outside air into the heating and cooling components for heating. The heated air then passes through the suction pipe and into the cover cylinder through the suction hole, raising the temperature inside the cover cylinder. Upon detecting deformation, the sampling hook straightens. Another fan in the fan unit starts, drawing air from the cover cylinder through the suction pipe. The resulting suction force is transmitted through the suction hole. Once the hooked cotton fiber is positioned on the suction hole, the clamping motor starts, driving the clamping screw to rotate. The clamping screw then drives the clamping mechanism... After the slider descends, the gear holding the upper block meshes with the deflection rack. The upper block changes from being perpendicular to the limit frame to being parallel to the limit frame. One end of the upper block slides into the inner wall of the groove of the limit frame and is then limited. The upper block is then lowered to press the cotton fibers on the lower block. The cover is reset and opened. The hydraulic cylinder on the lower block is activated. After the two lower blocks move in opposite directions, they pull the cotton fibers. The camera on the bracket records the breakage of the cotton fibers.

[0030] S4: After the test is completed, the clamped lower block moves on the limit guide rail under the action of the push hydraulic cylinder, so that the clamped lower block is reset. After the cover cylinder is closed, one of the fans in the fan unit starts. The air drawn by the fan is cooled by the heating and cooling components and then sent into the cover cylinder, so that the sampling hook is reset. The multi-stage telescopic hydraulic cylinder drives the push rod to reset. After the push rod drives the sampling sleeve to reset, the lifting hydraulic cylinder on the bracket pushes the recovery pipe to descend. After it is inserted into the inner wall of the cover cylinder, the fan connected to one end of the recovery pipe draws in the cotton fibers on the clamped lower block.

[0031] The beneficial effects of this invention are as follows:

[0032] 1. By setting up a sampling device, multiple samples of cotton fibers can be taken from within the cotton bale. The rotational force of the rotating sleeve facilitates the insertion of the sampling sleeve into the cotton bale, reducing damage to the cotton fibers. The deflection of the sampling hooks allows for the hooking of cotton fibers within the cotton bale, enabling sampling from multiple locations within the cotton bale. The sampling hooks are made of nickel-titanium alloy shape memory metal, which can deform under temperature influence, bending into a hook shape to hook the cotton fibers. After being exposed to hot air, they stand upright, facilitating the detachment of cotton fibers from the sampling hooks. This solves the technical problems of existing cotton fiber detection devices that require manual sampling of cotton bales before placing them in the detection device, reducing work efficiency, damaging the cotton fibers within the bale, affecting subsequent use of the cotton fibers, and resulting in inaccurate cotton fiber detection.

[0033] 2. By setting up a detection device, the cotton fibers sampled by the sampling device can be tested. The cotton fibers can be clamped by the relative movement of the lower clamping block and the upper clamping block, and the cotton fibers can be stretched to complete the strength test. The suction force in the suction pipe can generate suction in the cover cylinder, so that the detached cotton fibers can be adsorbed on the suction hole, which is convenient for the upper clamping block to hold, thus completing the strength test of the cotton fibers.

The outer surface of the electromagnetic ring 26 is magnetically connected to the inner wall of the top end of the sampling sleeve 23. The energization of the electromagnetic ring 26, the multi-stage telescopic hydraulic cylinder 24 and the rotary motor 22 can be achieved through a conductive ring. This is the prior art.

[0055] Specifically, in order to sample the cotton fibers inside the cotton bale, the sampling component includes a sampling hook 3. The sampling hook 3 is made of nickel-titanium alloy shape memory metal in the shape of a hook, and the outer surface is coated with silicon dioxide material. The sampling hook 3 is made of nickel-titanium alloy shape memory metal, which can be deformed by the influence of temperature. The alloy composition is adjusted, for example, by increasing the Ni content, and the deformation temperature is set at 50-80℃ to avoid burning the fibers. The sampling hook 3 is hinged to the inner wall of the sampling sleeve 23 by a pin. One end of the sampling hook 3 is hinged to a push rod 31 by a pin. The outer surface of the push rod 25 is rotatably connected to a rotating ring 32 through a bearing. One end of the push rod 31 is hinged to the outer surface of the rotating ring 32 by a pin.

The testing device includes an aggregation component and a testing component. The aggregation component wraps the sampling device, and the testing component performs strength testing on the cotton fibers clamped by the sampling component.

[0057] Specifically, to facilitate the collection of cotton fibers inside the sampling hook 3, the cotton fibers are gathered.

[0063] The present invention provides a detection method for a cotton fiber strength testing device, comprising the following steps:

[0064] S1: Conveyor line 1 conveys the cotton bales that need to be tested. After reaching the set position, the hydraulic cylinder in the push assembly 11 pushes the push plate to fix the cotton bales. After the rotary motor 22 on the rotary frame 2 starts, it drives the rotary sleeve 21 to rotate. At the same time, the multi-stage telescopic hydraulic cylinder 24 pushes the push rod 25 to move. The push rod 25 drives the sampling sleeve 23 to move. The sampling sleeve 23 moves inside the rotary sleeve 21. At the same time, the rotation of the rotary sleeve 21 drives the sampling sleeve 23 to rotate. The sampling sleeve 23 is inserted into the cotton bale. When the electromagnetic ring 26 is de-energized, the multi-stage telescopic hydraulic cylinder 24 retracts, causing the push rod 25 to move at the top of the sampling sleeve 23. After the rotating ring 32 moves, the push rod 31 pushes the sampling hook 3 to deflect and position it inside the cotton bale, where it hooks the cotton fibers. The push rod 25 moves under the push of the multi-stage telescopic hydraulic cylinder 24, and the sampling hook 3 resets. After the electromagnetic ring 26 is energized, it magnetically connects with the inner wall of the sampling sleeve 23. After the rotating turntable 12 starts, it drives the rotating frame 2 to rotate, and the sampling sleeve 23 is positioned above the open cover cylinder 46.

[0065] S2: After the drive motor 44 on the connecting frame 41 starts, it drives the transmission rod 43 to rotate through the transmission of the bevel gear set. The transmission rod 43 drives the turntable 45 to rotate. The rotation of the turntable 45 drives the moving block 42 to rise through the rod, and then drives the cover cylinder 46 to rise. The continuous rotation of the turntable 45 can drive the push handle 48 to rise through the trajectory of the arc groove. The push handle 48 can drive the cover cylinder 46 to deflect relatively through the deflection groove 47 and then close, so that the sampling sleeve 23 is located inside the cover cylinder 46, and the rotating sleeve 21 is inserted into one end of the cover cylinder 46.

[0066] S3: After the fan unit 73 starts, one of the fans in the fan unit 73 draws in external air into the heating and cooling component 72 for heating. The heated air can then enter the cover cylinder 46 through the suction pipe 71 and the suction hole 7, causing the temperature inside the cover cylinder 46 to rise. After the sampling hook 3 detects the deformation, the bent hook becomes upright. Another fan in the fan unit 73 starts, and the fan draws in the cover cylinder 46 through the suction pipe 71. The suction force generated is transmitted through the suction hole 7. After the hooked cotton fiber is located on the suction hole 7, the clamping motor 62 starts, driving the clamping screw 61 to rotate. The clamping screw 61 drives the clamping slide... After block 63 descends, the gear holding upper block 64 meshes with the deflection rack 65. After the direction of holding upper block 64 changes from perpendicular to the limiting frame 6 to parallel to the limiting frame 6, one end of holding upper block 64 slides into the inner wall of the groove of the limiting frame 6 and is limited, so that holding upper block 64 is limited. Holding upper block 64 descends and presses the cotton fibers on holding lower block 51. Cover cylinder 46 resets and opens. Push hydraulic cylinder 53 on holding lower block 51 is activated. After the two holding lower blocks 51 move in opposite directions, they pull the cotton fibers. The camera 81 on bracket 8 records the breakage of cotton fibers.

[0067] S4: After the test is completed, the clamping lower block 51 moves on the limit guide rail 5 under the action of the pushing hydraulic cylinder 53, so that the clamping lower block 51 is reset. After the cover cylinder 46 is closed, one of the fans in the fan unit 73 is started. The air drawn by the fan is cooled by the heating and cooling component 72 and then sent into the cover cylinder 46, so that the sampling hook 3 is reset. The multi-stage telescopic hydraulic cylinder 24 drives the pushing rod 25 to reset. After the pushing rod 25 drives the sampling sleeve 23 to reset, the lifting hydraulic cylinder 82 on the bracket 8 pushes the recovery pipe 83 to descend and insert it into the inner wall of the cover cylinder 46. The fan connected to one end of the recovery pipe 83 draws in the cotton fibers on the clamping lower block 51.

6. A method for detecting cotton fiber strength using a cotton fiber strength testing device as described in claim 5, characterized in that: S1: The conveyor line (1) conveys the cotton bales that need to be tested. After reaching the set position, the hydraulic cylinder in the push assembly (11) pushes the push plate to fix the cotton bales. The rotary motor (22) on the rotating frame (2) starts and drives the rotating sleeve (21) to rotate. At the same time, the multi-stage telescopic hydraulic cylinder (24) pushes the push rod (25) to move. The push rod (25) drives the sampling sleeve (23) to move. The sampling sleeve (23) moves inside the rotating sleeve (21). At the same time, the rotation of the rotating sleeve (21) drives the sampling sleeve (23) to rotate. The sampling sleeve (23) is inserted into the cotton bales. When the magnetic ring (26) is de-energized, the multi-stage telescopic hydraulic cylinder (24) retracts, driving the push rod (25) to move at the top of the sampling sleeve (23). After the rotating ring (32) moves, the push rod (31) pushes the sampling hook (3) to deflect and is located inside the cotton bag, hooking the cotton fibers inside the cotton bag. The push rod (25) moves under the push of the multi-stage telescopic hydraulic cylinder (24), and the sampling hook (3) resets. After the electromagnetic ring (26) is energized, it is magnetically connected to the inner wall of the sampling sleeve (23). After the rotating turntable (12) is started, it drives the rotating frame (2) to rotate, and the sampling sleeve (23) is located above the open cover cylinder (46). S2: After the drive motor (44) on the connecting frame (41) starts, it drives the transmission rod (43) to rotate through the transmission of the bevel gear set. The transmission rod (43) drives the turntable (45) to rotate. The rotation of the turntable (45) drives the moving block (42) to rise through the rod, and then drives the cover cylinder (46) to rise. The continuous rotation of the turntable (45) can drive the push handle (48) to rise through the trajectory of the arc groove. The push handle (48) can drive the cover cylinder (46) to deflect relatively through the deflection groove (47) and then close, so that the sampling sleeve (23) is located inside the cover cylinder (46). The rotating sleeve (21) is inserted into one end of the cover cylinder (46). S3: After the fan unit (73) is started, one of the fans in the fan unit (73) draws external air into the heating and cooling component (72) for heating. The heated air can enter the cover cylinder (46) through the suction pipe (71) and then through the suction hole (7), causing the temperature inside the cover cylinder (46) to rise. After the sampling hook (3) detects the deformation, the bent hook becomes upright. Another fan in the fan unit (73) starts. The fan draws into the cover cylinder (46) through the suction pipe (71). The suction force generated is transmitted through the suction hole (7). After the hooked cotton fiber is located on the suction hole (7), the clamping motor (62) starts, driving the clamping screw (61) to rotate. The clamping screw (61) drives the clamping slider. (63) After the descent, the gear of the clamping block (64) meshes with the deflection rack (65). After the clamping block (64) changes from a direction perpendicular to the limit frame (6) to a state parallel to the limit frame (6), one end of the clamping block (64) slides into the groove of the limit frame (6) and is limited, so that the clamping block (64) is limited. The clamping block (64) descends and presses the cotton fiber on the clamping lower block (51). The cover cylinder (46) is reset and opened. The pushing hydraulic cylinder (53) on the clamping lower block (51) is started. After the two clamping lower blocks (51) move in opposite directions, the clamped cotton fiber is pulled. The cotton fiber breakage is recorded by the camera (81) on the bracket (8). S4: After the test is completed, the clamping block (51) moves on the limit guide rail (5) under the action of the push hydraulic cylinder (53), so that the clamping block (51) is reset. After the cover cylinder (46) is closed, one of the fans in the fan group (73) is started. The air drawn by the fan is cooled by the heating and cooling component (72) and then sent into the cover cylinder (46), so that the sampling hook (3) is reset. The multi-stage telescopic hydraulic cylinder (24) drives the push rod (25) to be reset. After the push rod (25) drives the sampling sleeve (23) to be reset, the lifting hydraulic cylinder (82) on the bracket (8) pushes the recovery pipe (83) to descend. After being inserted into the inner wall of the cover cylinder (46), the fan connected to one end of the recovery pipe (83) sucks and recovers the cotton fibers on the clamping block (51).
