Description

Technical Field

[0001] The invention belongs to the technical field of thickness measurement, and in particular refers to a non-extrusion type natural thickness detection device for fiber textiles. Background Art

[0002] With the change of life and entertainment methods, the demand for outdoor sports and outdoor products has gradually increased in recent years, and therefore the demand for professional outdoor clothing with good cold-proof and warm-keeping effects has also been on the rise; outdoor clothing (especially in high-cold and high-altitude areas) has requirements for windproof and waterproof on the outermost fabric, and the inner fabric is required to have a certain fluffy thickness, which can form an insulation layer between the human body and the outside world while being lightweight, thereby reducing heat loss.

[0003] The current low-cost approach is to add fillings such as down, but because down jackets use squares to lock the filling, the thickness is extremely uneven. For professional people, there are differences in the warmth effect on different parts of the body. In addition, down jackets are overall too thick and bulky, and there are many limitations in the appearance design, which is not conducive to attracting high-spending groups who have high requirements for the appearance of clothing.

[0004] At present, there are some new fiber textile materials on the market that do not require filling, have a certain thickness, and are relatively soft. The thickness of this kind of material is uniform and flat, and it can be made thinner than down jackets with the same thermal insulation effect. It is an ideal choice as a thermal insulation layer of clothing. However, since the fine threads of this kind of textiles are not tightened during the textile production like ordinary cloth (not tightening is a necessary condition for the product to be fluffy and thick in the end), the thickness of the final product is not as uniform as ordinary cloth; therefore, before using it to sew clothes, its thickness needs to be tested first.

[0005] The current thickness detection method is mostly extrusion contact type, but the fabric itself is relatively soft, and the extrusion contact has a great impact on the measurement results; in addition, as clothing, it is also necessary to test the automatic rebound performance of this material after being compressed. Summary of the invention

[0006] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a non-extrusion type fiber textile natural thickness detection device. The core contradiction in the natural thickness detection of such fiber textiles lies in the balance between accuracy and material deformation. In order to more accurately feedback its thickness, it is necessary to adopt a non-contact detection method. Since the accuracy requirement of this working condition is not high, among the commonly used non-contact thickness measurement methods such as laser or X-ray measurement method, optical interference method, ultrasonic penetration method, millimeter wave radar measurement method, terahertz technology, etc., ultrasonic measurement with lower cost is a more economical choice. Whether it is ultrasonic or millimeter wave measurement, or other non-contact measurement solutions; the radar needs to periodically send and receive wave signals during the detection process, and the radar and the material need to remain relatively still for a period of time; this can be achieved through two solutions, the first is to let the material stop for detection, and the second is to let the radar briefly follow the movement of the material; among them, solution one is more suitable for laboratory environments, while in production environments where materials are continuously moving, solution two is obviously a more appropriate solution.

[0007] The reciprocating sliding of the non-contact detection device is divided into two stages. If the small gear and the large gear are equal in size, then during the resetting process of the non-contact detection device, the material to be tested will move the distance of a reciprocating rack. At this time, the non-contact detection device needs to cover at least the length of two reciprocating racks in the movement direction of the material to be tested to ensure the continuity of detection. Since the cost of non-contact detection devices is relatively high, the required specifications and power can be effectively reduced by reducing the coverage range of the non-contact detection device. Therefore, the present invention takes the lead in proposing a reciprocating gear assembly, which is provided with small gears and large gears of different sizes that work alternately. By shortening the reset time, the specification requirements of the non-contact detection device can be reduced, thereby reducing the cost.

[0008] The technical solution adopted by the present invention is as follows: The present invention proposes a non-extrusion type fiber textile natural thickness detection device, including an extrusion rebound test feeding mechanism, a detection radar synchronization mechanism and a driving assembly, the extrusion rebound test feeding mechanism is arranged on the driving assembly, and the detection radar synchronization mechanism is slidably arranged on the driving assembly; the extrusion rebound test feeding mechanism includes an extrusion feeding assembly and a synchronization assembly, the extrusion feeding assembly is symmetrically arranged on the driving assembly, and the synchronization assembly is arranged on two groups of extrusion feeding assemblies.

[0009] Furthermore, the extrusion feeding assembly includes a roller bracket, a bearing and a rotating roller, the roller bracket is arranged on the main base plate, the bearing is clamped in the roller bracket, both ends of the rotating roller are provided with a central axis, the central axis is clamped in the bearing, there is a gap between two rotating rollers in the same group, and the material to be tested is located between the two rotating rollers and is in rolling contact with the rotating rollers.

[0010] Preferably, the synchronization component includes a synchronization gear, a synchronization wheel and a synchronization belt, the synchronization gear is engaged on the central shaft, and the two rotating rollers in the longitudinal direction can rotate synchronously in opposite directions through the synchronization gear; the synchronization wheel is engaged on the central shaft, and the two rotating rollers in the transverse direction can rotate synchronously in the same direction through the synchronization wheel and the synchronization belt.

[0011] Driven by the driving component, two groups (four) of rollers can extrude and convey the material to be tested synchronously from two positions. On the one hand, the simultaneous conveying from two positions allows the material to be tested to maintain moderate force at the test position, avoiding the problem of excessive tension causing the thickness of the material to be tested to decrease, thereby ensuring the accuracy of the measurement; on the other hand, the extrusion that must be carried out during transportation can also cause the material to be tested to deform before testing. This step can test the rebound performance of the material to be tested on the basis of normal testing, further increasing the testing dimension and accuracy of product qualification.

[0012] Furthermore, the detection radar synchronization mechanism includes a reciprocating bracket and a reciprocating gear assembly, a reciprocating sliding assembly and a buffer reset assembly, the reciprocating sliding assembly is arranged on the driving assembly, the reciprocating bracket is arranged on the reciprocating sliding assembly, the reciprocating gear assembly is rotatably arranged on the extrusion feeding assembly, and the buffer reset assembly is symmetrically provided with two groups, and the buffer reset assembly is located at both ends of the reciprocating sliding assembly.

[0013] Preferably, the reciprocating gear assembly includes a reciprocating shaft, a pinion, a large gear and a reciprocating rack. The reciprocating shaft is detachably mounted on the central shaft. The pinion and the large gear are both engaged on the reciprocating shaft. Two reciprocating racks are provided. The reciprocating racks are fixed to a reciprocating bracket. The two reciprocating racks are respectively engaged with the pinion and the large gear for transmission.

[0014] By alternately meshing the small gear and the large gear with the reciprocating rack, the reciprocating bracket can be driven to slide reciprocatingly during the continuous rotation of the reciprocating shaft.

[0015] Among them, the teeth on the small gear and the large gear are distributed in a sector shape, the gear modules of the small gear and the large gear are equal, the number of teeth on the small gear and the large gear is equal, the sector area without distributed teeth on the small gear and the sector area with distributed teeth on the large gear are equal in angle and are arranged axially symmetrically; the small gear and the large gear can be alternately meshed with different reciprocating racks, and the reciprocating rack can achieve the effect of the same reciprocating sliding amplitude under different reciprocating sliding speeds.

[0016] By designing the tooth distribution on the pinion and the gear, the reset speed of the non-contact detection device can be made greater than the translation speed during detection, thereby reducing the required length of the non-contact detection device, improving the utilization rate of parts and reducing costs.

[0017] Preferably, the reciprocating sliding assembly comprises a guide rail, a slider and a slide plate, the guide rail is arranged on the main base plate, the slider is snap-fitted and slidably arranged on the guide rail, the slide plate is arranged on the slider, and the reciprocating bracket is arranged on the slide plate.

[0018] Furthermore, the detection radar synchronization mechanism also includes a non-contact detection device, which is arranged on the slide. The non-contact detection device can emit and receive waves, and feed back the thickness of the material to be measured through the time difference of wave reflection.

[0019] The non-contact detection device slides back and forth along with the reciprocating sliding assembly. When the sliding direction of the reciprocating sliding assembly is the same as the moving direction of the material to be tested, the non-contact detection device and the material to be tested remain relatively stationary for a period of time and perform detection; when the sliding direction of the reciprocating sliding assembly is opposite to the moving direction of the material to be tested, the non-contact detection device resets and does not perform detection.

[0020] Preferably, the buffer reset assembly comprises a fixed spring seat, a buffer spring and a buffer block, the fixed spring seat is fixedly connected to the main base plate, the buffer spring is arranged on the fixed spring seat, and the buffer block is arranged on the buffer spring.

[0021] On the one hand, the buffer spring can absorb the kinetic energy of the slide plate at the end of its sliding, reducing the impact on the gear. On the other hand, when the buffer spring is compressed, it can also provide a smaller reset force for the slide plate, thereby ensuring the smooth combination of the small gear and the reciprocating rack, as well as the large gear and the reciprocating rack.

[0022] Preferably, the buffer block is provided with a guide rod sliding in the fixed spring seat, and the guide rod can guide the sliding of the buffer block relative to the fixed spring seat.

[0023] Furthermore, the drive assembly also includes a motor seat, a drive motor, a coupling and a main base plate, the motor seat is arranged on the main base plate, the drive motor is arranged on the motor seat, and the output shaft and the center shaft of the drive motor are connected through a coupling.

[0024] The beneficial effects achieved by the present invention using the above structure are as follows: (1) Driven by the drive assembly, two groups (four) of rollers can squeeze and convey the material to be tested synchronously from two positions. On the one hand, the simultaneous conveying from two positions allows the material to be tested to maintain moderate force at the test position, avoiding the problem of excessive tension causing the thickness of the material to be tested to decrease, thereby ensuring the accuracy of the measurement; on the other hand, the extrusion that must be carried out during transportation can also cause the material to be tested to deform before testing. This step can test the rebound performance of the material to be tested on the basis of normal testing, further increasing the testing dimension and accuracy of product qualification.

[0025] (2) By alternately meshing the small gear and the large gear with the reciprocating rack, the reciprocating bracket can be driven to slide back and forth during the continuous rotation of the reciprocating shaft.

[0026] (3) By designing the tooth distribution on the pinion and the gear, the reset speed of the non-contact detection device can be made greater than the translation speed during detection, thereby reducing the required length of the non-contact detection device, improving the utilization rate of parts and reducing costs.

[0027] (4) The non-contact detection device slides back and forth along with the reciprocating sliding assembly. When the sliding direction of the reciprocating sliding assembly is the same as the moving direction of the material to be tested, the non-contact detection device and the material to be tested remain relatively stationary for a period of time and detection is performed; when the sliding direction of the reciprocating sliding assembly is opposite to the moving direction of the material to be tested, the non-contact detection device is reset and no detection is performed.

[0028] (5) On the one hand, the buffer spring can absorb the kinetic energy of the slide plate at the end of its sliding, reducing the impact on the gear. On the other hand, when the buffer spring is compressed, it can also provide a smaller reset force for the slide plate, thereby ensuring the smooth combination of the small gear and the reciprocating rack, as well as the large gear and the reciprocating rack.

[0034] like Figure 1 to Figure 11 As shown, the present invention proposes a non-extrusion type fiber textile natural thickness detection device, including an extrusion rebound test feeding mechanism 1, a detection radar synchronization mechanism 2 and a driving component 3, the extrusion rebound test feeding mechanism 1 is arranged on the driving component 3, and the detection radar synchronization mechanism 2 is slidably arranged on the driving component 3.

[0035] The driving assembly 3 also includes a motor base 29 , a driving motor 30 , a coupling 31 and a main base plate 32 . The motor base 29 is disposed on the main base plate 32 , the driving motor 30 is disposed on the motor base 29 , and the output shaft of the driving motor 30 and the central shaft 13 are connected via the coupling 31 .

[0036] The extrusion rebound test feeding mechanism 1 comprises an extrusion feeding component 4 and a synchronization component 5 . The extrusion feeding component 4 is symmetrically arranged on the driving component 3 , and the synchronization component 5 is arranged on two groups of extrusion feeding components 4 .

[0037] The extrusion feeding assembly 4 includes a roller bracket 6, a bearing 7 and a rotating roller 8. The roller bracket 6 is arranged on the main bottom plate 32. The bearing 7 is clamped in the roller bracket 6. Central shafts 13 are provided at both ends of the rotating roller 8. The central shaft 13 is clamped in the bearing 7. There is a gap between the two rotating rollers 8 of the same group. The material 9 to be tested is located between the two rotating rollers 8 and is in rolling contact with the rotating rollers 8.

[0038] The synchronous assembly 5 includes a synchronous gear 10, a synchronous wheel 11 and a synchronous belt 12. The synchronous gear 10 is engaged with the central shaft 13, and the two rotating rollers 8 in the longitudinal direction can rotate synchronously in opposite directions through the synchronous gear 10; the synchronous wheel 11 is engaged with the central shaft 13, and the two rotating rollers 8 in the transverse direction can rotate synchronously in the same direction through the synchronous wheel 11 and the synchronous belt 12.

[0039] Driven by the driving component 3, two groups (four) of rollers can synchronously extrude and convey the material 9 to be tested from two positions. On the one hand, the simultaneous conveying from two positions allows the material 9 to be tested to maintain moderate force at the tested position, avoiding the problem of excessive tension causing the thickness of the material 9 to be reduced, thereby ensuring the accuracy of the measurement; on the other hand, the extrusion that must be performed during transportation can also cause the material 9 to be tested to deform before testing. This step can test the rebound performance of the material 9 to be tested on the basis of normal testing, further increasing the testing dimension and accuracy of product qualification.

[0040] The detection radar synchronization mechanism 2 includes a reciprocating bracket 14 and a reciprocating gear assembly 15, a reciprocating sliding assembly 16 and a buffer reset assembly 17. The reciprocating sliding assembly 16 is arranged on the driving assembly 3, the reciprocating bracket 14 is arranged on the reciprocating sliding assembly 16, the reciprocating gear assembly 15 is rotatably arranged on the extrusion feeding assembly 4, and the buffer reset assembly 17 is symmetrically arranged in two groups, and the buffer reset assembly 17 is located at both ends of the reciprocating sliding assembly 16.

[0041] The reciprocating gear assembly 15 includes a reciprocating shaft 19, a pinion 20, a large gear 21 and a reciprocating rack 22. The reciprocating shaft 19 is detachably mounted on the central shaft 13. The pinion 20 and the large gear 21 are both engaged with the reciprocating shaft 19. Two reciprocating racks 22 are provided. The reciprocating racks 22 are fixedly connected to the reciprocating bracket 14. The two reciprocating racks 22 are respectively engaged with the pinion 20 and the large gear 21 for transmission.

[0042] By the small gear 20 and the large gear 21 alternately meshing with the reciprocating rack 22 , the reciprocating bracket 14 can be driven to slide reciprocatingly during the continuous rotation of the reciprocating shaft 19 .

[0043] The teeth on the pinion 20 and the large gear 21 are distributed in a sector shape, the gear modules of the pinion 20 and the large gear 21 are equal, the number of teeth on the pinion 20 and the large gear 21 are equal, the sector area without distributed teeth on the pinion 20 and the sector area with distributed teeth on the large gear 21 are equal in angle and are arranged axially symmetrically; the pinion 20 and the large gear 21 can be alternately meshed with different reciprocating racks 22, and the reciprocating rack 22 can achieve the same reciprocating sliding amplitude under different reciprocating sliding speeds.

[0044] By designing the tooth distribution on the small gear 20 and the large gear 21, the reset speed of the non-contact detection device 18 can be made greater than the translation speed during detection, thereby reducing the required length of the non-contact detection device 18, improving the utilization rate of parts and reducing costs.

[0045] The reciprocating sliding assembly 16 includes a guide rail 23 , a slider 24 and a slide plate 25 . The guide rail 23 is disposed on the main base plate 32 . The slider 24 is slidably disposed on the guide rail 23 . The slide plate 25 is disposed on the slider 24 . The reciprocating bracket 14 is disposed on the slide plate 25 .

[0046] The detection radar synchronization mechanism 2 also includes a non-contact detection device 18, which is arranged on the slide 25. The non-contact detection device 18 can emit and receive waves, and feed back the thickness of the material 9 to be detected through the time difference of wave reflection.

[0047] The non-contact detection device 18 slides back and forth following the reciprocating sliding assembly 16. When the sliding direction of the reciprocating sliding assembly 16 is the same as the moving direction of the material 9 to be tested, the non-contact detection device 18 and the material 9 to be tested remain relatively stationary for a period of time and perform detection; when the sliding direction of the reciprocating sliding assembly 16 is opposite to the moving direction of the material 9 to be tested, the non-contact detection device 18 is reset and no detection is performed.

[0048] The buffer reset assembly 17 includes a fixed spring seat 26 , a buffer spring 27 and a buffer block 28 . The fixed spring seat 26 is fixedly connected to the main bottom plate 32 , the buffer spring 27 is arranged on the fixed spring seat 26 , and the buffer block 28 is arranged on the buffer spring 27 .

[0049] On the one hand, the buffer spring 27 can absorb the kinetic energy of the slide plate 25 at the end of its sliding, reducing the impact on the gear. On the other hand, when the buffer spring 27 is compressed, it can also provide a smaller reset force for the slide plate 25, thereby ensuring the smooth combination of the small gear 20 and the reciprocating rack 22, as well as the large gear 21 and the reciprocating rack 22.

[0050] The buffer block 28 is provided with a guide rod that slides in the fixed spring seat 26 , and the guide rod can guide the sliding of the buffer block 28 relative to the fixed spring seat 26 .

[0051] like Fig.12 As shown, the smallest circle represents the reciprocating shaft 19, the second largest circle outside the reciprocating shaft 19 represents the pinion 20, and the largest circle represents the large gear 21; the major arc region (dash-dot line) separated by straight lines a and b on the pinion 20 represents the region where teeth are distributed on the pinion 20, and the minor arc region (dash-dot line) separated by straight lines a and b on the large gear 21 represents the region where teeth are distributed on the large gear 21; the upper and lower dash-dot line segments represent the reciprocating rack 22; In actual application, the angle between lines a and b is not necessarily a right angle, but the following points must be guaranteed: First, the expanded length of the dotted major arc on the pinion 20 is equal to the effective length of the reciprocating rack 22, and the expanded length of the dotted minor arc on the large gear 21 is equal to the effective length of the reciprocating rack 22, so as to ensure that the sliding amplitude of the reciprocating bracket 14 in both directions is equal; Second: Based on the first point, the diameter of the small gear 20 is smaller than the diameter of the large gear 21, which can ensure that the reciprocating bracket 14 can be reset at a faster speed; in the detection stage, the non-contact detection device 18 moves synchronously with the material 9 to be detected, and the movement amplitude of the material 9 to be detected during this process remains constant. Therefore, the faster the reset speed, the smaller the movement amplitude of the material 9 to be detected in the entire round trip cycle, thereby reducing the width (along the movement direction of the material 9 to be detected) range requirement of the non-contact detection device 18 and reducing costs; Third: the line a connecting the meshing end point of the pinion 20 and the meshing starting point of the large gear 21 passes through the center of the circle, so that the large gear 21 can be combined with the reciprocating rack 22 after the pinion 20 and the reciprocating rack 22 are separated; the line b connecting the meshing end point of the large gear 21 and the meshing starting point of the pinion 20 passes through the center of the circle, so that the pinion 20 can be combined with the reciprocating rack 22 after the large gear 21 and the reciprocating rack 22 are separated.

[0052] When in use, the user first needs to place the material 9 to be tested in the gap between the rotating rollers 8, and then start the driving motor 30 to rotate one rotating roller 8 through the coupling 31. Under the linkage of the synchronous belt 12, the two horizontal rotating rollers 8 can rotate synchronously in the same direction, and under the linkage of the synchronous gear 10, the two longitudinal rotating rollers 8 can rotate synchronously in opposite directions, so that the material 9 to be tested is squeezed and continuously transported without being stretched; The rotating roller 8 rotates with the reciprocating shaft 19, and at the same time, the small gear 20 and the large gear 21 on the reciprocating shaft 19 rotate together. During the rotation process, the small gear 20 and the large gear 21 are alternately meshed with different reciprocating racks 22. When the small gear 20 is meshed with the upper reciprocating rack 22, the reciprocating bracket 14 pushes the slide plate 25 to slide. At this time, the movement direction and movement speed of the slide plate 25 are the same as those of the material 9 to be tested. When the pinion 20 is meshed with the reciprocating rack 22 below, the reciprocating bracket 14 pushes the slide plate 25 to slide in the opposite direction. At this time, the movement direction of the slide plate 25 is opposite to that of the material 9 to be tested. Since the diameter of the large gear 21 is larger than that of the pinion 20, the movement speed of the slide plate 25 is greater than that of the material 9 to be tested. During the unidirectional continuous rotation of the reciprocating shaft 19, the reciprocating bracket 14 can push the slide plate 25 to slide reciprocatingly; when the non-contact detection device 18 and the material to be measured 9 slide synchronously, the non-contact detection device 18 will periodically emit and receive waves, and feedback the thickness of the material to be measured 9 through the time difference of wave reflection; the non-contact detection device 18 does not perform measurement work when it is reset.

[0053] As another embodiment of the present invention, when the slide plate 25 slides to the vicinity of the extreme position at any end, it will hit the buffer block 28. Through the compression of the buffer spring 27, on the one hand, it can absorb its kinetic energy at the end of the slide of the slide plate 25 and reduce the impact of inertia on the gear. On the other hand, when the buffer spring 27 is compressed, it can also provide a smaller reset force for the slide plate 25, thereby ensuring the smooth combination of the small gear 20 and the reciprocating rack 22, as well as the large gear 21 and the reciprocating rack 22.

[0054] The locations where the inspection fails will be marked by the software and will not affect the continuous operation of the material.

[0055] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0056] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
