Description

Technical Field

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

[0002] With the transformation of lifestyle for entertainment, the demand for outdoor sports and outdoor products has gradually increased in recent years. Therefore, the demand for professional outdoor clothing with good cold protection and warmth retention has also shown an upward trend. Outdoor clothing (especially in high-cold and high-altitude areas) has requirements for windproof and waterproof properties on the outermost fabric, while the inner fabric is required to have a certain fluffy thickness, which can form a thermal insulation layer between the human body and the outside world while being lightweight, reducing heat loss.

[0003] Currently, the low-cost approach is to add fillers such as down. However, since down jackets lock the fillers through square grids, the thickness is extremely uneven, and there are differences in the warmth retention effect of different parts for professional users. Moreover, the overall down jacket is too heavy and bulky, with many limitations in appearance design, which is not conducive to attracting high-consumption groups with high requirements for clothing appearance.

[0004] Currently, there are some new fiber textile materials on the market that do not require filling and have a certain thickness by themselves and are relatively soft. Such materials have uniform thickness, are flat, and can be made thinner than down jackets under the same heat preservation effect, making them an ideal choice for clothing thermal insulation layers. However, since such textiles are not tightened like ordinary fabrics during textile production (not tightening is a necessary condition for the final product to be fluffy and have thickness), the thickness of the final product is not as uniform as that of ordinary fabrics. Therefore, before being used for sewing clothes, it is necessary to detect its thickness first.

[0005] Currently, most thickness detection methods are extrusion contact type. However, the fabric itself is relatively soft, and the extrusion contact has too much influence on the measurement result. In addition, as clothing, it is also necessary to detect the automatic rebound performance of this material after being pressed. Summary of the Invention

[0006] In view of the above situation, to overcome the defects of the prior art, the present invention provides a non-extrusion type natural thickness detection device for fiber textiles. 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 reflect its thickness, it is necessary to adopt a non-contact detection method. Since the requirement for accuracy in 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.

[0007] Whether it is ultrasonic or millimeter-wave measurement, or other non-contact measurement solutions; during the detection process, the radar needs to periodically transmit and receive wave signals, and there needs to be a period of relative rest between the radar and the material; this can be achieved through two solutions. The first is to stop the material for inspection, and the second is to let the radar briefly follow the movement of the material. Among them, the first solution is more suitable for the laboratory environment, while in the production environment where the material moves continuously, the second solution is obviously a more appropriate solution.

[0008] The reciprocating sliding of the non-contact detection device is divided into two stages. If the small gear and the large gear are of the same size, then during the reset process of the non-contact detection device, the material to be measured will move another distance of the reciprocating rack. At this time, in the moving direction of the material to be measured, the non-contact detection device needs to cover at least the length of two reciprocating racks to ensure the continuity of detection. Since the cost of the non-contact detection device is relatively high, by reducing the coverage range of the non-contact detection device, the required specifications and power can be effectively reduced. Therefore, the present invention first proposes a reciprocating gear assembly, which sets small gears and large gears of different sizes and alternating work. By shortening the reset time, the specification requirements of the non-contact detection device can be reduced, thereby reducing the cost.

[0009] The technical solution adopted by the present invention is as follows: The present invention proposes a non-extrusion type natural thickness detection device for fiber textiles, which includes an extrusion and rebound test feeding mechanism, a detection radar synchronization mechanism, and a driving component. The extrusion and rebound test feeding mechanism is arranged on the driving component, and the detection radar synchronization mechanism is slidably arranged on the driving component; the extrusion and rebound test feeding mechanism includes an extrusion feeding component and a synchronization component. The extrusion feeding components are symmetrically arranged on the driving component, and the synchronization component is arranged on two groups of extrusion feeding components.

[0010] Further, the extrusion feeding component includes a roller bracket, a bearing, and a rotating roller. The roller bracket is arranged on the main bottom plate, the bearing is snap-fitted in the roller bracket, the two ends of the rotating roller are provided with central shafts, and the central shafts are snap-fitted in the bearings. There is a gap between two rotating rollers in the same group, and the material to be measured is located between the two rotating rollers and is in rolling contact with the rotating rollers.

[0011] Preferably, the synchronization component includes a synchronization gear, a synchronization wheel, and a synchronization belt. The synchronization gear is snap-fitted 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 snap-fitted 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.

[0012] Driven by the driving component, two groups (four) of rollers can synchronously extrude and convey the material to be measured from two positions. On the one hand, the simultaneous conveyance at the two positions enables the material to be measured to be appropriately stressed at the position to be measured, avoiding the problem that the thickness of the material to be measured becomes smaller due to excessive tension, thus ensuring the accuracy of the measurement. On the other hand, the extrusion that is necessarily carried out during conveyance can also cause the material to be measured to deform before detection. Based on the normal detection, this step can just detect the resilience performance of the material to be measured; further increasing the detection dimension and accuracy of product qualification.

[0013] Furthermore, the detection radar synchronization mechanism includes a reciprocating bracket, a reciprocating gear assembly, a reciprocating sliding assembly, and a buffer reset assembly. The reciprocating sliding assembly is arranged on the driving component, the reciprocating bracket is arranged on the reciprocating sliding assembly, the reciprocating gear assembly is rotatably arranged on the extrusion feeding component, two groups of the buffer reset assemblies are symmetrically arranged, and the buffer reset assemblies are located at both ends of the reciprocating sliding assembly.

[0014] Preferably, the reciprocating gear assembly includes a reciprocating rotating shaft, a small gear, a large gear, and a reciprocating rack. The reciprocating rotating shaft is detachably arranged on the central shaft, the small gear and the large gear are both engaged and arranged on the reciprocating rotating shaft, two reciprocating racks are provided, the reciprocating racks are fixedly connected to the reciprocating bracket, and the two reciprocating racks are respectively meshed and driven with the small gear and the large gear.

[0015] By the way that the small gear and the large gear alternately mesh with the reciprocating rack, the reciprocating bracket can be driven to reciprocate during the continuous rotation of the reciprocating rotating shaft.

[0016] Among them, the teeth on the small gear and the large gear are distributed in a fan shape. The module of the small gear and the large gear is equal, the number of teeth on the small gear and the large gear is equal. The fan-shaped area without teeth distribution on the small gear and the fan-shaped area with teeth distribution on the large gear have equal angles and are arranged axially symmetrically; it can enable the small gear and the large gear to alternately mesh with different reciprocating racks respectively, and the reciprocating rack can achieve the effect of the same reciprocating sliding amplitude under the condition of different reciprocating sliding speeds.

[0017] Through the design of the tooth distribution on the small gear and the large 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.

[0018] Preferably, the reciprocating sliding assembly includes a guide rail, a slider, and a sliding plate. The guide rail is arranged on the main base plate, the slider is engaged and slidably arranged on the guide rail, the sliding plate is arranged on the slider, and the reciprocating bracket is arranged on the sliding plate.

[0019] Furthermore, the detection radar synchronization mechanism further includes a non-contact detection device, which is arranged on the sliding plate. The non-contact detection device can emit and receive waves, and feedback the thickness of the material to be measured through the time difference of wave reflection.

[0020] The non-contact detection device reciprocates 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 measured, the non-contact detection device and the material to be measured are relatively stationary for a period of time for detection; when the sliding direction of the reciprocating sliding assembly is opposite to the moving direction of the material to be measured, the non-contact detection device resets and does not perform detection.

[0021] Preferably, the buffer reset assembly includes a fixed spring seat, a buffer spring and a buffer block. The fixed spring seat is fixedly connected to the main bottom plate, the buffer spring is arranged on the fixed spring seat, and the buffer block is arranged on the buffer spring.

[0022] On the one hand, the buffer spring can absorb the kinetic energy at the end of the sliding of the sliding plate, reducing the impact on the gear. On the other hand, when the buffer spring is compressed, it can also provide a small reset force for the sliding plate, thus ensuring the smooth engagement of the small gear and the reciprocating rack, as well as the large gear and the reciprocating rack.

[0023] Preferably, a guide rod sliding in the fixed spring seat is arranged on the buffer block, and the guide rod can guide the sliding of the buffer block relative to the fixed spring seat.

[0024] Furthermore, the driving assembly further includes a motor seat, a driving motor, a coupling and a main bottom plate. The motor seat is arranged on the main bottom plate, the driving motor is arranged on the motor seat, and the output shaft of the driving motor is connected to the central shaft through the coupling.

[0025] The beneficial effects achieved by the present invention with the above structure are as follows:

[0026] (1) Driven by the driving assembly, two groups (four) of rollers can synchronously extrude and convey the material to be measured from two positions. On the one hand, the simultaneous conveying at two positions enables the material to be measured to maintain appropriate stress at the position to be measured, avoiding the problem that the thickness of the material to be measured becomes smaller due to excessive tension, thus ensuring the accuracy of measurement; on the other hand, the extrusion that must be carried out during conveying can also deform the material to be measured before detection. This step, on the basis of normal detection, can just detect the resilience performance of the material to be measured; further increasing the detection dimension and accuracy of product qualification.

[0027] (2) By the way that the small gear and the large gear alternately engage with the reciprocating rack, the reciprocating bracket can be driven to reciprocate during the continuous rotation of the reciprocating rotating shaft.

[0028] (3) By designing the tooth distribution on the pinion and the large gear, the reset speed of the non-contact detection device can be made greater than the translation speed during detection, thereby reducing the length of the non-contact detection device required, improving the utilization rate of components, and reducing costs.

[0029] (4) The non-contact detection device reciprocates with the reciprocating sliding component. When the sliding direction of the reciprocating sliding component is the same as the movement direction of the material to be measured, the non-contact detection device and the material to be measured are relatively stationary for a period of time for detection; when the sliding direction of the reciprocating sliding component is opposite to the movement direction of the material to be measured, the non-contact detection device resets and does not perform detection.

[0030] (5) On the one hand, the buffer spring can absorb the kinetic energy at the end of the sliding of the sliding plate, reducing the impact on the gear. On the other hand, when the buffer spring is compressed, it can also provide a small reset force for the sliding plate, thus ensuring the smooth engagement of the pinion and the reciprocating rack, as well as the large gear and the reciprocating rack.

[0047] Such as Figures 1 to 11As shown in the figure, the present invention provides a non-extrusion type natural thickness detection device for fiber textiles, which includes an extrusion and rebound test feeding mechanism 1, a detection radar synchronization mechanism 2, and a driving component 3. The extrusion and 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.

[0048] The driving component 3 further includes a motor base 29, a driving motor 30, a coupling 31, and a main base plate 32. The motor base 29 is arranged on the main base plate 32, the driving motor 30 is arranged on the motor base 29, and the output shaft of the driving motor 30 is connected to the central shaft 13 through the coupling 31.

[0049] The extrusion and rebound test feeding mechanism 1 includes 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 sets of extrusion feeding components 4.

[0050] The extrusion feeding component 4 includes a roller bracket 6, a bearing 7, and a rotating roller 8. The roller bracket 6 is arranged on the main base plate 32, the bearing 7 is snap-fitted in the roller bracket 6, the two ends of the rotating roller 8 are provided with central shafts 13, the central shafts 13 are snap-fitted in the bearings 7, there is a gap between two rotating rollers 8 in the same group, and the material to be tested 9 is located between the two rotating rollers 8 and is in rolling contact with the rotating rollers 8.

[0051] The synchronization component 5 includes a synchronization gear 10, a synchronization pulley 11, and a synchronization belt 12. The synchronization gear 10 is snap-fitted on the central shaft 13, and two rotating rollers 8 in the longitudinal direction can rotate synchronously in opposite directions through the synchronization gear 10; the synchronization pulley 11 is snap-fitted on the central shaft 13, and two rotating rollers 8 in the transverse direction can rotate synchronously in the same direction through the synchronization pulley 11 and the synchronization belt 12.

[0052] Driven by the driving component 3, two groups (four) of rollers can synchronously extrude and convey the material to be tested 9 from two positions. On the one hand, the simultaneous conveyance at two positions enables the material to be tested 9 to be properly stressed at the position to be tested, avoiding the problem that the thickness of the material to be tested 9 becomes smaller due to excessive tension, thus ensuring the accuracy of the measurement; on the other hand, the inevitable extrusion during conveyance can also cause the material to be tested 9 to deform before detection. This step, on the basis of normal detection, can just detect the rebound performance of the material to be tested 9; further increasing the detection dimension and accuracy of product qualification.

[0053] The detection radar synchronization mechanism 2 includes a reciprocating bracket 14, 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, two groups of buffer reset assemblies 17 are symmetrically arranged, and the buffer reset assemblies 17 are located at both ends of the reciprocating sliding assembly 16.

[0054] The reciprocating gear assembly 15 includes a reciprocating rotating shaft 19, a small gear 20, a large gear 21, and a reciprocating rack 22. The reciprocating rotating shaft 19 is detachably arranged on the central shaft 13, the small gear 20 and the large gear 21 are both clamped on the reciprocating rotating shaft 19, two reciprocating racks 22 are provided, the reciprocating racks 22 are fixedly connected to the reciprocating bracket 14, and the two reciprocating racks 22 are respectively meshed and driven with the small gear 20 and the large gear 21.

[0055] By means of the small gear 20 and the large gear 21 alternately meshing with the reciprocating rack 22, the reciprocating bracket 14 can be driven to reciprocate during the continuous rotation of the reciprocating rotating shaft 19.

[0056] The teeth on the small gear 20 and the large gear 21 are fan-shaped distributed, the gear modules of the small gear 20 and the large gear 21 are equal, the number of teeth on the small gear 20 and the large gear 21 are equal, the fan-shaped area without teeth distribution on the small gear 20 and the fan-shaped area with teeth distribution on the large gear 21 have equal angles and are axially symmetrically arranged; it can enable the small gear 20 and the large gear 21 to alternately mesh with different reciprocating racks 22 respectively, and the reciprocating rack 22 can achieve the effect of the same reciprocating sliding amplitude under different reciprocating sliding speeds.

[0057] Through the design of 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.

[0058] The reciprocating sliding assembly 16 includes a guide rail 23, a slider 24, and a sliding plate 25. The guide rail 23 is arranged on the main bottom plate 32, the slider 24 is clamped and slid on the guide rail 23, the sliding plate 25 is arranged on the slider 24, and the reciprocating bracket 14 is arranged on the sliding plate 25.

[0059] The detection radar synchronization mechanism 2 further includes a non-contact detection device 18. The non-contact detection device 18 is arranged on the sliding plate 25. The non-contact detection device 18 can emit and receive waves, and feedback the thickness of the material to be measured 9 through the time difference of wave reflection.

[0060] The non-contact detection device 18 reciprocates along with 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 to be measured 9, the non-contact detection device 18 and the material to be measured 9 are relatively stationary for a period of time for detection; when the sliding direction of the reciprocating sliding assembly 16 is opposite to the moving direction of the material to be measured 9, the non-contact detection device 18 resets and does not perform detection.

[0061] 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 base 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.

[0062] On the one hand, the buffer spring 27 can absorb the kinetic energy of the sliding 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 small reset force for the sliding plate 25, so as to ensure the smooth engagement of the pinion 20 and the reciprocating rack 22, as well as the large gear 21 and the reciprocating rack 22.

[0063] 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.

[0064] As Figure 12 shown, the smallest circle represents the reciprocating rotating shaft 19, the second largest circle outside the reciprocating rotating shaft 19 represents the pinion 20, and the largest circle represents the large gear 21; the major arc region (dotted line) separated by the 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 (dotted line) separated by the 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 dotted line segments represent the reciprocating rack 22;

[0065] In actual application, the included angle between the straight lines a and b is not necessarily a right angle, but the following points need to be ensured:

[0066] First: The developed length of the major arc of the dotted line on the pinion 20 is equal to the effective length of the reciprocating rack 22, and the developed length of the minor arc of the dotted line on the large gear 21 is equal to the effective length of the reciprocating rack 22, so as to ensure that the sliding amplitudes of the reciprocating support 14 in both directions are equal;

[0067] Second: Based on the first point, the diameter of the pinion gear 20 is smaller than that of the large gear 21, which can ensure that the reciprocating support 14 can be reset at a faster speed; during the detection stage, the non-contact detection device 18 moves synchronously with the material to be measured 9. During this process, the movement amplitude of the material to be measured 9 remains constant. Therefore, the faster the reset speed, the smaller the movement amplitude of the material to be measured 9 during the entire round-trip cycle, and thus the smaller the range requirement of the width of the non-contact detection device 18 (along the movement direction of the material to be measured 9), reducing costs;

[0068] Third: The connecting line a between the meshing end point of the pinion gear 20 and the meshing starting point of the large gear 21 passes through the center of the circle, which enables the large gear 21 to engage with the reciprocating rack 22 after the pinion gear 20 separates from the reciprocating rack 22; the connecting line b between the meshing end point of the large gear 21 and the meshing starting point of the pinion gear 20 passes through the center of the circle, which enables the pinion gear 20 to engage with the reciprocating rack 22 after the large gear 21 separates from the reciprocating rack 22.

[0069] During specific use, first, the user needs to place the material to be measured 9 in the gap between the rotating rollers 8, and then start the drive motor 30. Through the coupling 31, one of the rotating rollers 8 is driven to rotate. Under the linkage of the synchronous belt 12, the two horizontal rotating rollers 8 can rotate synchronously in the same direction. Under the linkage of the synchronous gears 10, the two vertical rotating rollers 8 can rotate synchronously in opposite directions, so that the material to be measured 9 can be continuously conveyed under extrusion without being stretched;

[0070] When the rotating roller 8 rotates, it will drive the reciprocating rotating shaft 19 to rotate, and at the same time drive the pinion gear 20 and the large gear 21 located on the reciprocating rotating shaft 19 to rotate together. During the rotation process, the pinion gear 20 and the large gear 21 respectively alternately engage with different reciprocating racks 22. When the pinion gear 20 engages with the upper reciprocating rack 22, the reciprocating support 14 pushes the sliding plate 25 to slide. At this time, the movement direction and speed of the sliding plate 25 are the same as those of the material to be measured 9;

[0071] When the pinion gear 20 engages with the lower reciprocating rack 22, the reciprocating support 14 pushes the sliding plate 25 to slide in the reverse direction. At this time, the movement direction of the sliding plate 25 is opposite to that of the material to be measured 9. Since the diameter of the large gear 21 is larger than that of the pinion gear 20, the movement speed of the sliding plate 25 is greater than that of the material to be measured 9;

[0072] During the unidirectional continuous rotation of the reciprocating rotating shaft 19, the reciprocating support 14 can push the sliding plate 25 to slide back and forth; when the non-contact detection device 18 slides synchronously with the material to be measured 9, 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 during reset.

[0073] As another embodiment of the present invention, when the skateboard 25 slides near the extreme position at either end, it will hit the buffer block 28. Through the compression of the buffer spring 27, on the one hand, it can absorb the kinetic energy of the skateboard 25 at the end of its sliding, reducing the impact of inertia on the gear. On the other hand, when the buffer spring 27 is compressed, it can also provide a small restoring force for the skateboard 25, thus ensuring the smooth engagement of the pinion 20 and the reciprocating rack 22, as well as the large gear 21 and the reciprocating rack 22.

[0074] The unqualified positions detected will be marked by the software and will not affect the continuous operation of the material.

[0075] It should be noted that in this article, relational terms such as first and second 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 term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0076] The present invention and its embodiments have been described above. This description is not restrictive, and only one of the embodiments of the present invention is shown in the drawings. The actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural modes and embodiments without creative efforts without departing from the purpose of the present invention, they shall fall within the protection scope of the present invention.
