Description

Technical Field

[0001] The invention relates to the technical field of fiber length laser measurement, in particular to a fiber length measurement mechanism for a triple-proof fabric. Background Art

[0002] Fiber length is an important criterion for measuring fiber quality and a key factor affecting yarn quality. When measuring the fiber length of three-proof fabric, it is necessary to first remove the PVC, PTFE, and other coatings on the surface of the three-proof fabric, then cut the fabric into pieces to form rags. After that, the rags are combed to remove broken and damaged fibers, leaving intact fibers for laser measurement. Laser measurement is used to measure the fiber length of three-proof fabrics. Generally, a clamping structure is required to clamp the rags, which are then combed by a combing structure. The combed rags are then hung and straightened, and finally measured by a laser measuring device. For example, the textile fiber length measuring device disclosed in Publication No. CN116182718B is equipped with a fiber fixing structure, a fiber straightening and leveling structure, and a fiber bundle straightening structure. After the fiber bundle is straightened, a fan-shaped laser is emitted by a laser transmitter to measure the fiber length. However, the above-mentioned prior art cannot effectively comb the fibers during use. This is because, when the fibers are being combed, if they are relatively dry, the comb roller is difficult to comb. When the comb roller is stuck, the comb roller continues to rotate, which will tear the fibers, making it difficult to effectively comb the fibers. Therefore, a fiber length measurement mechanism for triple-proof fabrics is needed to solve the above problems. Summary of the Invention

[0014] Compared with the prior art, the present invention has the following advantages: the fiber length measuring mechanism of the triple-proof cloth can not only prevent the combing mechanism from applying excessive force and causing damage to the rags, but also prevent the combing mechanism from being damaged by forces in two opposite directions. In addition, the mechanism can spray water onto the rags to soften the fibers, which is beneficial for the brush plate to comb the rags: 1. By starting the servo motor 1, the screw can be driven to rotate. The rotation of the screw can realize the movement of the whole structure composed of the follower block and the threaded block along the axis of the screw, and then the sliding block connected to it can be driven to move along the axis of the screw by the spring 1. During the process, the mounting plate moves synchronously with the sliding block, so that the brush plate can comb the rags. During the combing process, if the rags are too messy and the brush plate is stuck, the sliding block will no longer move downward. However, at this time, the whole structure composed of the follower block and the threaded block will not stop moving downward, which will cause the spring 1 to be squeezed and make The driving plate is in contact with the sliding block, so that the driving plate moves relative to the following block, thereby allowing the threaded block to move away from the screw rod through the shaft block 1 and the oblique through hole 1. At the moment when the threaded block is disconnected from the screw rod, the whole formed by the following block and the threaded block will no longer continue to move downward, thereby avoiding the following block from continuously moving downward and causing the force of squeezing the sliding block to be too large, so that the force of the brush plate combing the rags is too large, resulting in damage to the rags. At the same time, it also protects the brush plate and prevents the brush plate from being damaged by the large downward squeezing force of the following block and the upward pulling force of the rags. 2. When the follower block is approaching the sliding block below it, the limit block will gradually approach the sliding block below it, thereby causing the support bar to drive the piston disc to move upward in the piston flat tube, thereby squeezing the gas in the piston flat tube above the piston disc, so that the gas in the piston flat tube above the piston disc enters the piston cover through the air guide pipe, so that the piston plate and the lower pressure shaft move downward, thereby squeezing the inclined groove, and moving the brush plate toward the inside of the mounting plate, to prevent the bristles on the brush plate from being entangled with the rags, which will cause the brush plate to move upward when the fixed position is moved upward, making it impossible to effectively comb the rags. During the process, the support tube, support shaft and spring five can ensure that the position of the support bar hardly changes, thereby helping to ensure that the position of the brush plate relative to the mounting plate hardly changes, which is beneficial for the brush plate to no longer carry the rags upward during the upward movement. 3. After the overall structure composed of the follower block and the threaded block moves to the upper ends of the support bar and the drive plate and contacts the corresponding support blocks respectively, it will be squeezed by the support blocks, causing the support bar and the drive plate to move downward, which not only prevents the overall structure composed of the follower block and the threaded block from continuing to move upward, but also allows the piston disc on the support bar to move downward relative to the piston flat tube, and then the water in the piston flat tube below the piston disc can be squeezed into the water flow chamber through the one-way liquid guide tube, and then sprayed to the rags through the spray hole, so as to soften the fibers that make up the rags, which is conducive to the subsequent smooth combing and reduces the possibility of the brush plate being stuck due to drying of the rags.

[0018] See also Figures 1-14 , the present invention provides the following technical solutions: Embodiment 1: In order to solve the problem that the fiber length measuring mechanism in the past has insufficient stability when clamping rags, which easily causes the rags to fall off when combing the rags, the following technical solution is provided, specifically, a three-proof cloth fiber length measuring mechanism, including a support base 1 and a support frame 2 fixedly connected to its upper surface, the support base 1 is also fixedly connected to a light receiving plate 3 and a mounting frame 4, and the light receiving plate 3 and the mounting frame 4 are respectively arranged on both sides of the support frame 2, the inner top bearing of the mounting frame 4 is connected to the upper end of the screw shaft 5, and the lower end bearing of the screw shaft 5 passes through the bottom of the support base 1, the lower surface of the support base 1 is installed with a servo motor 1 8 and a servo motor 2 9, and the lower end of the screw shaft 5 is coaxially connected to the output end of the servo motor 2 9, a connecting frame 6 is slidably connected to the mounting frame 4, and a laser emitter 7 is installed on the connecting frame 6, the connecting frame 6 is threaded through by the screw shaft 5, a clamping and fixing mechanism is provided on the support frame 2, and the clamping and fixing mechanism includes a clamping plate 11 for clamping the rags.

[0019] The clamping and fixing mechanism also includes a screw tube 12 mounted on the upper surface of the support frame 2, and the upper end opening of the screw tube 12 is threadedly connected to the adjusting rod 16. The upper surface of the support frame 2 is also axially connected to two symmetrical rockers 14, and the upper surface of the rocker 14 close to the end of the adjusting rod 16 is in contact with and connected to a pressing component 15. The pressing component 15 is bearing-connected to the outer side of the adjusting rod 16. Limiting holes 40 are provided at both ends of the upper surface of the support frame 2, and the lower ends of the corresponding limiting rods 41 are extended into the openings of the limiting holes 40. The upper ends of the two limiting rods 41 are connected to L-shaped follower plates 38, and each follower plate 38 is provided with two oblique through holes 237. A spring 439 is provided between the lower surface of the upper end of the follower plate 38 and the upper surface of the support frame 2, and both sides of the support frame 2 are connected. The surfaces are provided with strip slots, and the two strip slots are respectively arranged corresponding to the corresponding oblique through holes 37. The upper ends of the two splints 11 are symmetrically slidably connected to the inner top surface of the support frame 2, and both ends of each splint 11 are fixedly connected to the shaft block 2 36, and the shaft block 2 36 moves through the corresponding strip slots and the corresponding oblique through holes 37 in turn. The ends of the two rockers 14 away from the adjusting rod 16 are respectively extended to the lower part of the upper end of the corresponding follower plate 38. The pressing assembly 15 includes an n-shaped frame plate for squeezing the end of the rocker 14 and an n-shaped frame connecting the two n-shaped frame plates. The middle part of the n-shaped frame is penetrated by the bearing of the adjusting rod 16. The two oblique through holes 37 on the follower plate 38 are distributed in an eight-shaped shape, which facilitates the movement of the two splints 11 close to each other when the two follower plates 38 move up, thereby facilitating the clamping of the rags.

[0020] according to Figure 2-Figure 3 as well as Figure 7-Figure 8 When in use, the adjusting rod 16 is rotated, and the adjusting rod 16 moves upward, driving the pressing assembly 15 to move upward synchronously, so that the pressing assembly 15 no longer tightly squeezes one end of the rocker 14, and the other end thereof gradually moves downward due to the pull of the spring 4 39. At the same time, the following plate 38 also moves downward, and the two splints 11 can be moved away from each other through the shaft block 2 36 and the oblique through hole 2 37; Then, the upper end of the rag is pushed between the two clamping plates 11, and the adjusting rod 16 is rotated in the opposite direction to move the adjusting rod 16 downward, so that the pressing assembly 15 moves downward and gradually squeezes one end of the seesaw 14 (the ratio of the distance between the rotation center of the seesaw 14 and its two ends is not less than 3, and the distance between the end of the seesaw 14 pressed by the pressing assembly 15 and its rotation center is longer). At this time, its other end will tilt up and then lift the follower plate 38. During the upward movement of the follower plate 38, the two clamping plates 11 will approach each other due to the second shaft block 36 and the second oblique through hole 37, thereby stably clamping the rag.

[0021] Embodiment 2: In order to solve the problem that the combing structure of the previous fiber length measuring mechanism can only move back and forth up and down in the original position when combing the rags, and cannot effectively comb the rags, the following technical solution is provided. Specifically, a screw 10 is movably passed through the support base 1, and the lower end of the screw 10 is coaxially connected to the output end of the servo motor 8. The support base 1 is also fixedly connected to a limit shaft 42 parallel to the screw 10, and the upper ends of the screw 10 and the limit shaft 42 are connected to the support frame 2 through corresponding support blocks 13. A combing mechanism is arranged between the screw 10 and the limit shaft 42, and the combing mechanism includes a brush plate 28 for combing the rags. The combing mechanism is provided with a water spray mechanism and a telescopic mechanism.

[0022] The combing mechanism also includes a follower block 19 that is movably sleeved on the outside of the screw 10, and a mounting groove 20 is provided on the inner side of the follower block 19. A mounting rod 25 that is movable and penetrates into the mounting groove 20 is provided on the follower block 19, and a spring 26 that is sleeved on the outside of the middle part of the mounting rod 25 is provided between the outer end of the mounting rod 25 and the outer side of the follower block 19, and the mounting rod 25 is a T-shaped structure. The inner end of the mounting rod 25 extending into the mounting groove 20 is fixedly connected to a threaded block 21, and the threaded block 21 is threadedly connected to the screw 10, limiting A limit block 43 is movably sleeved on the positioning shaft 42, and the limit block 43 and the follower block 19 are respectively fixedly connected to the two ends of the strip plate, and a sliding block 17 is movably sleeved on the outside of the screw 10 and the limit shaft 42, and the two sliding blocks 17 are connected by a mounting plate 27, and the brush plate 28 is movably extended into the open end of the mounting plate 27. The two sliding blocks 17 are both slidably connected to the support frame 2 through a roller assembly 47, and a spring 18 sleeved on the outside of the screw 10 is provided between the follower block 19 and the sliding block 17 directly below it.

[0023] according to Figure 3-Figure 6 When the servo motor 18 drives the screw 10 to rotate, the threaded block 21 is threadedly connected to the screw 10, and the limit block 43 limits the follower block 19, so that the entire structure composed of the follower block 19 and the threaded block 21 can move along the axial direction of the screw 10. Because the follower block 19 is connected to the sliding block 17 directly below it by the spring 18, the follower block 19 can also drive the sliding block 17 to move downward during the downward movement. When the sliding block 17 moves downward, the mounting plate 27 connected to the sliding block 17 moves downward synchronously therewith, thereby driving the brush plate 28 connected to the mounting plate 27 to move downward synchronously, so that the rags can be combed by the bristles on the brush plate 28.

[0024] The telescopic mechanism includes a connecting plate 45 fixedly connected to the upper surface of the limit block 43, a piston flat tube 44 is fixedly passed through the limit block 43, and a support bar 48 is passed through the piston flat tube 44, the two ends of the piston flat tube 44 are respectively penetrated by the two ends of the support bar 48 for seamless sliding, and the lower end of the support bar 48 is in contact with the upper surface of the corresponding sliding block 17, the outer side of the middle part of the support bar 48 is fixedly connected to the piston disc 54, and the piston disc 54 is seamlessly slidably connected to the inner side of the piston flat tube 44, the outer side axis of the connecting plate 45 is connected to two support tubes 51 symmetrically distributed in a V shape, the upper end protrusion of the support bar 48 is connected to two support shafts 52 symmetrically distributed in a V shape, and the support tube 51 is sleeved on the outer side of the corresponding support shaft 52, supporting A spring five 53 is provided between the open end of the support tube 51 and the outer side of the support shaft 52. The telescopic mechanism also includes a piston cover 33 provided on the upper surface of the mounting plate 27, and a piston piece 34 is seamlessly slidably connected inside the piston cover 33. Down-pressing shafts 35 are evenly spaced on the lower surface of the piston piece 34, and the down-pressing shaft 35 is movable through the inner side of the mounting plate 27. An inclined groove 31 is provided on the upper surface of the brush plate 28, and the inclined surface of the inclined groove 31 is in contact with the hemispherical lower end of the down-pressing shaft 35. Spring three 32 is evenly distributed between the end of the brush plate 28 extending into the mounting plate 27 and the inner top end of the mounting plate 27. The inner side of the piston cover 33 above the piston piece 34 is connected to the inner side of the piston flat tube 44 above the piston disc 54 through the air guide pipe 50.

[0025] according to Figure 5-Figure 6 as well as Figure 13-14 As the limiting block 43 gradually approaches the sliding block 17 directly below it, the support bar 48 is squeezed, causing the piston disc 54 to move upward in the piston flat tube 44, thereby squeezing the gas in the piston flat tube 44 above the piston disc 54, so that the gas enters the piston cover 33 through the air guide pipe 50, thereby increasing the air pressure in the piston cover 33; When the air pressure in the piston cover 33 increases, the piston plate 34 inside it drives the pressing shaft 35 to move downward, squeezing the chute 31, causing the brush plate 28 to move toward the inside of the mounting plate 27, thereby preventing the brush plate 28 from moving upward in its original position, causing the rags to be entangled and making it impossible to effectively comb the rags. In the above process, the structure composed of the support tube 51, the support shaft 52 and the spring 53 can ensure that the position of the support bar 48 hardly changes after the movement, thereby ensuring that the brush plate 28 no longer extends into the rags to prevent the brush plate 28 from being entangled with the rags.

[0026] The water spraying mechanism includes a water flow chamber 29 arranged inside the brush plate 28, and spray holes 30 that pass through the water flow chamber 29 are evenly distributed on the brush plate 28. The spray holes 30 and the bristles on the brush plate 28 are arranged on the same side. The water flow chamber 29 is connected to the inner side of the piston flat tube 44 below the piston disc 54 through a one-way liquid guide tube 49, and the inner side of the piston flat tube 44 below the piston disc 54 also passes through the one-way liquid inlet interface 46 to the outside of the limit block 43.

[0027] according to Figure 5-Figure 6 as well as Figure 13-14 After the limit block 43 moves up along with the overall structure composed of the follower block 19 and the threaded block 21, the support bar 48 contacts the support block 13 and is squeezed, which will cause the support block 13 to move in the opposite direction, thereby allowing the piston disc 54 to move downward in the piston flat tube 44, thereby squeezing the water in the piston flat tube 44 below the piston disc 54, so that the water enters the water chamber 29 through the one-way liquid guide tube 49, and is then sprayed toward the rags from the spray hole 30, thereby softening the fibers that make up the rags, which is beneficial for the brush plate 28 to comb the rags and reduce the possibility of the rags being entangled on the brush plate 28.

[0028] Example 3: In order to solve the problem that when combing rags, the combing structure of the previous fiber length measuring mechanism is stuck with the rags, and the combing structure continues to press down, which may easily cause damage to the rags and may even cause damage to the combing structure, the following technical solution is provided. Specifically, the combing mechanism is also provided with an anti-pressure damage mechanism.

[0029] The anti-pressure loss mechanism includes two through holes that movably penetrate the follower block 19, and each through hole is penetrated by a drive plate 24. The two through holes are both connected to the mounting groove 20. The two drive plates 24 are each provided with an oblique through hole 23 that penetrates both sides thereof, and each oblique through hole 23 is slidably penetrated by a corresponding shaft block 22. The two shaft blocks 22 are respectively fixedly connected to both sides of the threaded block 21. The structural shape of the oblique through hole 23 is a V-shape after being rotated 90°. The two drive plates 24 are both located between the overlapping parts of the corresponding sliding block 17 and the corresponding support block 13.

[0030] according to Figure 3-Figure 4 After the brush plate 28 is stuck by the rags and no longer presses down, the integral structure composed of the follower block 19 and the threaded block 21 continues to move downward, gradually squeezing the spring 18 until the driving plate 24 is squeezed by the sliding block 17 below it, and the threaded block 21 can be moved away from the screw 10 through the shaft block 12 and the oblique through hole 12. The moment the threaded block 21 is disconnected from the screw 10, the integral structure composed of the follower block 19 and the threaded block 21 will no longer move along the axial direction of the screw 10 due to the rotation of the screw 10, thereby preventing the brush plate 28 from continuing to apply pressure to the rags, so as to avoid breaking the rags or damaging the brush plate 28.

[0031] The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0032] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
