Description

Technical Field

[0001] The invention relates to the technical field of textile product detection, in particular to a method for detecting the length of cashmere fibers in textile production. Background Art

[0002] When processing cashmere textiles, it is necessary to measure the length of cashmere fibers. Chinese Patent Publication No. CN206208207U discloses a device for measuring the length of loose cashmere fibers. The device comprises a housing, a light source, and a light-receiving module mounted on the upper and lower surfaces of the housing, respectively. The centers of the light source and receiving module are aligned vertically. A support plate and a base are provided on the front and rear sides of the receiving module, respectively. A fleece cloth is bonded to the upper surface of the support plate. A counterweight is provided just above one end of the support plate near the receiving module, connected to the upper surface of the housing via a telescopic rod. The base has an electric slide rail on its upper surface, and a comb clip is mounted on the upper surface of the slider in the electric slide rail.

[0003] The length detection device in the above-mentioned prior art combs the cashmere by a combing clamp during detection, thereby facilitating the detection of the cashmere length. However, since dry cashmere is prone to curling, especially when the cashmere is combed by the combing clamp, the friction generated will cause the cashmere to curl. Therefore, the curled cashmere will affect the detection accuracy of the cashmere length.

[0004] Therefore, we propose a method for detecting cashmere fiber length in textile production. Summary of the Invention

DETAILED DESCRIPTION

[0055] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0056] See also Figures 1-10 The present invention provides a technical solution: a cashmere fiber length detection device for textile production, comprising a base plate 1 and support plates 2 provided at both ends of the base plate 1, the support plates 2 being vertically welded to the two horizontal ends of the base plate 1, and the detection device further comprising:

[0057] A rotatable cloth clamping device connected to the two support plates 2, the cloth clamping device is used to clamp the two ends of the cashmere textile so that the cashmere textile is roughly straightened;

[0058] The water spraying device is provided on the two support plates 2 and is located above the two cloth clamping devices. The water spraying device can spray water onto the cashmere surface of the cashmere textile, so that the cashmere fibers are humidified and their own weight increases;

[0059] The two ends of the horizontal plate 4 are respectively connected to the two support plates 2. The length direction of the horizontal plate 4 is perpendicular to the mid-perpendicular line of the line connecting the two cloth clamping devices. The two ends of the horizontal plate 4 in the length direction can be welded to the two support plates 2.

[0060] A sliding block 17 slidably connected to the horizontal plate 4, and the sliding block 17 can move along the length direction of the horizontal plate 4;

[0061] The combing device provided on the sliding block 17 can comb the cashmere fibers after being sprayed with water to avoid the cashmere fibers from being entangled.

[0062] The two ends of the cashmere textile are respectively placed on two cloth clamping devices, which clamp the two ends of the cashmere textile to straighten the cashmere textile. The water spraying device then sprays water onto the cashmere surface of the cashmere textile to increase the weight of the cashmere fibers after humidification. The sliding block 17 moves along the length direction of the horizontal plate 4, so that the combing device can comb the cashmere fibers. After combing, the cloth clamping device is flipped 180°, so that the side of the cashmere textile that was originally facing upward is flipped to face downward.

[0063] like Figure 1 As shown, the cloth clamping device includes:

[0064] By installing a mounting plate that is rotatably connected to the support plate 2 via a pivot, the pivot can be rotatably connected to the support plate 2 via a mounting bearing, thereby enabling the mounting plate to rotate;

[0065] The two clamping cylinders 6 are connected to the mounting plate, and the two clamping cylinders 6 are installed horizontally opposite to each other, that is, the two clamping cylinders 6 are symmetrically arranged with the mid-perpendicular line connecting the two support plates 2 as the axis;

[0066] The pressure plates 7 are connected to the clamping jaws of the clamping cylinder 6 in groups of two. Specifically, each clamping jaw of each clamping jaw cylinder 6 is connected to a pressure plate 7 by a screw, and a clamping space is formed between two adjacent pressure plates 7, and the end of the cashmere textile is placed in the clamping space.

[0067] By starting the clamping cylinder 6 , the clamping jaws of the clamping cylinder 6 move closer to each other, and drive the pressing plates 7 to move closer to each other, so that the pressing plates 7 can clamp the cashmere textile.

[0068] like Figure 1 、 6 As shown, the two support plates 2 are connected to a rotating shaft 3 for horizontal rotation. The two ends of the rotating shaft 3 are respectively provided with a first pulley, and the two pivots are each provided with a second pulley. A V-belt is commonly provided between the first pulley and the second pulley. The rotating shaft 3 is driven to rotate by a first motor 10 installed on the support plate 2. The first motor 10 is energized to rotate and drives the rotating shaft 3 to rotate. When rotating, it can drive the first pulley to rotate. Since the first pulley and the second pulley are driven by the V-belt, the first pulley and the second pulley can rotate synchronously, and the two pivots can be driven to rotate. When rotating, it can drive the two clamping cylinders 6 to rotate.

[0069] like Figure 1 As shown, the water spraying device includes:

[0070] The fixed tube 12 is fixed at both ends to the upper ends of the two support plates 2. A pipe interface (not shown in the figure) is provided on the outer wall of the fixed tube 12. An external water pump is connected to the pipe interface through a water pipe, so that the water pump is connected to the fixed tube 12. When the water pump is started, deionized water is delivered to the fixed tube 12.

[0071] A nozzle 13 connected to the fixed pipe 12 and with its mouth facing the cloth clamping device is used to spray the deionized water in the fixed pipe 12 out from the nozzle 13 , thereby spraying the deionized water onto the cashmere surface of the cashmere textile.

[0072] like Figure 6 As shown, a ball screw 15 is connected to the horizontal plate 4 for horizontal rotation. The ball screw 15 is threaded through the sliding block 17, and the ball screw 15 is driven to rotate by a second motor 14 installed on the horizontal plate 4. The second motor 14 is powered and rotated, and drives the ball screw 15 to rotate, so that the ball screw 15 is threadedly engaged with the sliding block 17, thereby driving the sliding block 17 to move horizontally.

[0073] like Figure 4 As shown, the sliding block 17 is provided with a sliding pin 22, and the horizontal plate 4 is provided with a sliding groove 5 for the sliding pin 22 to be inserted and can slide freely along the length direction of the horizontal plate 4. When the sliding pin 22 slides in the sliding groove 5, the sliding block 17 can be slidably connected to the horizontal plate 4, and the sliding block 17 can be prevented from rotating.

[0074] like Figure 2 As shown, the combing device includes:

[0075] A support fixed to the top of the sliding block 17, on which a third motor 18 is mounted;

[0076] The swing arm 19 is driven and connected to the motor shaft of the third motor 18, and the swing arm 19 is a tubular structure;

[0077] A connecting arm 20 is threadedly provided on the swing arm 19. The connecting arm 20 is L-shaped, and its horizontal section is threadedly inserted into the swing arm 19. By screwing the thread on the swing arm 19, the length of the horizontal section of the connecting arm 20 extending out of the swing arm 19 can be adjusted.

[0078] The combing plate 8 is fixed to the connecting arm 20, and the length direction of the combing plate 8 is consistent with the length direction of the cross plate 4. The combing plate 8 is provided with a plurality of comb teeth. When the third motor 18 is energized and drives the ball screw 15 to rotate, it can drive the sliding block 17 to move. When the sliding block 17 moves, it will drive the swing arm 19 and the connecting arm 20 to move, so that the combing plate 8 can comb the cashmere fibers to prevent the cashmere fibers from being entangled.

[0079] like Figure 2As shown, a fixed plate is located at the bottom of the slider 17, on which an industrial camera 16 is mounted. Industrial camera 16 is a key component in a machine vision system. Its most essential function is to convert optical signals into ordered electrical signals. Selecting the right camera is also a crucial step in machine vision system design. The choice of camera not only directly determines the resolution and quality of the captured images, but also directly relates to the overall system operation mode. Industrial camera 16 is connected to a computer's visual processing module, which processes the cashmere fiber images captured by industrial camera 16, thereby enabling the length of the cashmere fibers to be detected. Both industrial camera 16 and the visual processing module are conventional structures and will not be further elaborated here.

[0080] like Figure 6 、 7 As shown in FIG8 , one of the support plates 2 is provided with a beating device, which includes:

[0081] A mounting arm 25 connected to the mounting plate, wherein the mounting arm 25 is screwed to the mounting plate;

[0082] A rotating ring 27 rotatably connected to the mounting arm 25 via a mounting hinge shaft;

[0083] A beating rod 21 is fixed to the rotating ring 27 and extends toward the middle of the two support plates 2. A beating frame 9 is provided at one end of the beating rod 21 away from the rotating ring 27.

[0084] A driving rod 26 fixedly connected to the rotating ring 27 and extending away from the beating rod 21, the driving rod 26 is L-shaped, and the horizontal section of the driving rod 26 is fixedly connected to the rotating ring 27;

[0085] The ball 28 is rotatably mounted on the vertical section of the driving rod 26. Specifically, a spherical groove is formed at the end of the vertical section of the driving rod 26. The ball 28 is mounted in the spherical groove and can rotate freely.

[0086] A fixing ring 11 is fixed to the support plate 2. A plurality of notches 23 are formed in an axial array on the wall of the inner ring hole of the fixing ring 11. Balls 28 can roll on the inner wall of the notches 23 and the wall of the inner ring hole of the fixing ring 11.

[0087] The two ends of the tension spring 24 are respectively fixed to the mounting plate and the beating rod 21.

[0088] When the ball 28 rolls on the wall of the inner ring hole of the fixed ring 11, the driving rod 26 will drive the rotating ring 27 to rotate, so that the beating rod 21 is away from the cashmere textile and the tension spring 24 is in a stretched state. When the ball 28 rolls from the wall of the inner ring hole of the fixed ring 11 to the notch groove 23, the tension spring 24 will pull the beating rod 21 to swing rapidly in the opposite direction, thereby causing the beating frame 9 to swing toward the direction close to the cashmere textile, and then causing the beating frame 9 to beat the other side of the cashmere textile, so that the water on the cashmere fibers of the cashmere textile can be shaken off, and the cashmere fibers are straightened.

[0089] This embodiment also discloses a method for detecting the length of cashmere fibers in textile production, comprising:

[0090] Place the two ends of the cashmere textile in the clamping space surrounded by the two sets of pressing plates 7, with the cashmere surface of the cashmere textile facing upwards, and start the clamping claw cylinder 6, which drives the two adjacent pressing plates 7 to move relative to each other and clamp the ends of the cashmere textile, so that the cashmere textile is tightened;

[0091] An external water pump delivers deionized water to the fixed pipe 12 through a water pipe, and then multiple nozzles 13 spray the deionized water onto the cashmere surface of the cashmere textile to humidify the cashmere surface.

[0092] The third motor 18 is started, and the motor shaft of the third motor 18 rotates, driving the swing arm 19 to swing toward the cashmere textile until the combing plate 8 contacts the cashmere surface of the cashmere textile. The second motor 14 is then started, and the second motor 14 drives the ball screw 15 to rotate. The ball screw 15 is threadedly engaged with the sliding block 17, thereby driving the sliding block 17 to move horizontally. During the horizontal movement, the combing plate 8 can comb the cashmere surface of the cashmere textile, straightening the cashmere fibers. The third motor 18 then rotates in the opposite direction, causing the swing arm 19 to swing away from the cashmere textile, and the external water pump is turned off at the same time.

[0093] The first motor 10 is started to drive the rotating shaft 3 to rotate, so that the first pulley and the second pulley rotate synchronously, thereby driving the pivot to rotate, so that the two clamping cylinders 6 rotate synchronously in the same direction, thereby being able to flip the cashmere textile;

[0094] When the pivot rotates, the balls 28 on the vertical section of the driving rod 26 roll alternately on the hole wall of the inner ring hole of the fixed ring 11 and the inner wall of the notch groove 23. When the balls 28 roll on the hole wall of the inner ring hole of the fixed ring 11, the driving rod 26 will drive the rotating ring 27 to rotate, so that the slapping rod 21 is away from the cashmere textile and the tension spring 24 is in a stretched state. When the balls 28 roll from the hole wall of the inner ring hole of the fixed ring 11 to the notch groove 23, the tension spring 24 will pull the slapping rod 21 to swing rapidly in the opposite direction, thereby causing the slapping frame 9 to swing in the direction close to the cashmere textile, and then causing the slapping frame 9 to slap the other side of the cashmere textile, so that the water on the cashmere fibers of the cashmere textile can be shaken off, and the cashmere fibers are straightened.

[0095] When the gripper cylinder 6 rotates 180°, the second motor 14 starts again and drives the ball screw 15 to rotate. During the rotation, it can drive the sliding block 17 to move horizontally and start the industrial camera 16 at the same time. The industrial camera 16 is used to capture images of the cashmere fibers. The images captured by the industrial camera 16 are then processed by an external computer device to analyze the length of the cashmere fibers.
