Description

Technical Field

[0001] The present invention relates to the technical field of physical testing, and particularly to a multi-station detection device for fabric elasticity testing. Background Technique

[0002] Fabric refers to a sheet material made by fibers through weaving, knitting or other methods. It can be made of natural fibers such as cotton, wool, silk, etc., or can be made of chemically synthesized fibers such as polyester, nylon, spandex, etc.

[0003] Elasticity detection of fabric can evaluate the anti-deformation ability of the fabric during long-term use, judge whether it can still maintain the original size and shape after repeated stretching, and avoid problems such as relaxation and damage of the fabric in a short time after leaving the factory due to excessive stretching. Therefore, the elasticity test before fabric leaving the factory is particularly important.

[0004] However, the existing multi-station detection devices for fabric elasticity testing have the following deficiencies: With the development of technology, mechanical equipment with different functions can be combined and coordinated with each other to form a modern multi-station assembly line, which greatly improves the fabric output efficiency. However, due to the limitations of its own structure, most of the existing elasticity testing equipment still adopts relatively traditional testing methods and cannot be used in combination with multi-station production lines. The operation steps are numerous, and the manual participation in the operation of the equipment is large, resulting in too low testing efficiency.

[0005] Since the fabric production involves many processes, when a batch of fabric is produced, due to various external factors, it is impossible to ensure that all are qualified. However, the existing elasticity testing equipment can only provide a single testing method and cannot perform intermittent testing. Its test results cannot represent the elastic performance of the whole batch of fabric, and the low data accuracy directly affects the subsequent positioning of product quality and sales promotion.

[0006] The present invention proposes a multi-station detection device for fabric elasticity testing to facilitate the solution of the problems raised above. Summary of the Invention

[0007] The purpose of the present invention is to provide a multi-station detection device for fabric elasticity testing. By setting an intermittent pressure application mechanism and a release clamping mechanism, the mechanism can build a fabric transportation platform, and the device can be installed between the forming machine and the winding machine. And with the use of the winding equipment, it is ensured that the installation of the device into the multi-station platform will not interfere with the fabric production. When the device is running, the fabric can continuously pass parallel above the device. The positions of the test components are reasonably arranged.

A second associated frame is fixedly installed between every two opposite clamping sleeves. A second merging frame is fixedly installed between the tops of the two second associated frames. The second merging frame is connected to the bottom of the wiring base.

[0012] Preferably, a solid seat is installed between the tops of each group of metal sliding rods. An arc-shaped cover plate is fixedly installed on the top of each solid seat. An anti-slip pad is wrapped on the outer surface of each arc-shaped cover plate. A group of active springs are fixedly installed between each solid seat and the horizontal plate.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By setting an intermittent pressing mechanism and a releasing and clamping mechanism, the mechanism can construct a fabric conveying platform, and the device can be set up between a forming machine and a winding machine. In cooperation with the use of a winding device, it is ensured that the device will not interfere with the fabric generation when set up on a multi-station platform. During the operation of the device, the fabric can continuously pass parallel above the device. The positions of the test components are reasonably arranged. Each time a test is carried out, a part of the fabric to be tested can be quickly intercepted, so that all steps required for the test do not need to be participated by manual labor. The mechanism solves many drawbacks existing in traditional devices through the operation mode of the cooperation between the system module and the mechanical components, effectively reduces the operation difficulty of the device, improves the fabric test efficiency, optimizes the operation mode, and reduces the labor cost.

[0019] 2. By setting an intermittent pressing mechanism and a releasing and clamping mechanism, the mechanism can be disassembled into four main components, namely a driving component, a traveling component, a limiting component and a test component. The four components cooperate with each other during operation. The driving component is controlled by relevant modules of the device system. When the set start interval time is set, every time an opening period arrives, the test component is pushed with the assistance of the traveling component and the limiting component, and is slowly lifted to directly apply an external force to one side of the fabric to cause it to deform. Combining the self-adaptability of the device main body and the multi-station production line, multiple elastic tests can be carried out on a batch of continuously produced fabrics to ensure that the subsequent obtained results are more accurate, providing necessary data support for the formulation of product positioning and sales plans.

[0020] 3. By setting a release clamping mechanism in the present invention, when the fabric moves forward stably on the running component, the relevant components and the winding device can generate a certain degree of tensile force on the fabric, so that the fabric running directly above the device can be in a straightened state. When intercepting a part of the fabric for testing, the set mechanical components can synchronously clamp both ends of the selected fabric tightly, so that this part of the fabric quickly stops moving and maintains its initial state. The purpose is to ensure that when applying pressure to the fabric subsequently, the fabrics at both ends will not be drawn in, affecting the test results, accelerating the test process, enabling the production line to return to normal faster, and preventing excessive accumulation of fabric at one end of the device, which may cause inconsistent output and collection rates.

Detailed implementation mode

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to the attached Figure 1 - attached Figure 8 As shown, the present invention provides a technical solution: a multi-station detection device for fabric elasticity testing, including an assembly frame 1, an upper support plate 2 fixedly installed at the top of the assembly frame 1, a square window 3 opened at the center of the upper support plate 2, an intermittent pressing mechanism 4 provided at the bottom of the assembly frame 1, and a release clamping mechanism 5 provided at the top of the upper support plate 2.

[0026] Example 1, such as Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown in the figure, the intermittent pressure applying mechanism 4 includes two lower support plates 401, both of which are fixedly installed at the bottom of the assembly frame 1. A pneumatic component 402 is fixedly installed at the bottom of each lower support plate 401. A first connection frame 403 is fixedly sleeved at the shaft end of each pneumatic component 402. A first merging frame 408 is fixedly installed on the opposite side of the two first connection frames 403. Two groups of support plates 404 are fixedly installed at the bottom of the assembly frame 1. A group of sliding sleeves 405 are fixedly installed on the outer wall of each support plate 404. A cooperative sliding plate 406 is movably arranged inside each group of sliding sleeves 405. Each first merging frame 408 is respectively connected to a corresponding group of cooperative sliding plates 406. A clamping sleeve 407 is fixedly installed on the outer wall of each cooperative sliding plate 406. A second connection frame 409 is fixedly installed between every two opposite clamping sleeves 407. A second merging frame 410 is fixedly installed between the tops of the two second connection frames 409. The second merging frame 410 is connected to the bottom of the wiring base 411.

[0027] The overall effect achieved by the entire Example 1 is as follows: By presetting the above components, this part of the components altogether includes two main structures. One is the driving part, and the other is the limiting part. The two cooperate with each other. During operation, the driving part is controlled by relevant modules of the equipment system. When the interval time between each start is set, every time an opening period arrives, with the assistance of the limiting component, the test component is pushed, slowly lifted, and an external force is directly applied to one side of the fabric, causing it to deform. Combining the self - adaptability of the equipment main body and the multi - station production line, multiple elastic tests can be carried out on a batch of continuously produced fabrics, ensuring that the subsequent obtained results are more accurate and providing necessary data support for the formulation of product positioning and sales plans.

[0028] Example 2, as Figure 5 、 Figure 6 and Figure 7As shown in the figure, a wiring base 411 is movably arranged inside the square window 3. A macro camera 413 and two fill light plates 414 are respectively fixedly connected to the top of the wiring base 411. Hollow shell sleeves 412 are fixedly installed on both sides of the outer wall of the wiring base 411. A pressure sensing component 425 is fixedly connected to the bottom of the inner wall of each hollow shell sleeve 412. A cross plate 420 is fixedly installed inside the hollow shell sleeve 412. A group of first hollow sleeves 421 are fixedly installed inside the cross plate 420. A metal sliding rod 422 is movably inserted into each first hollow sleeve 421. A pressing buckle 424 is fixedly installed at the bottom of each metal sliding rod 422. A solid seat 417 is installed between the tops of each group of metal sliding rods 422. An arc-shaped cover plate 418 is fixedly installed on the top of each solid seat 417. An anti-slip pad 419 is wrapped on the outer surface wall of each arc-shaped cover plate 418. A group of active springs 423 are fixedly installed between each solid seat 417 and the cross plate 420. Each active spring 423 is respectively movably sleeved on the outer surface wall of a corresponding metal sliding rod 422.

[0029] The effect achieved by the entire Embodiment 2 is as follows: By presetting the above components, according to Hooke's law it can be known that when the fabric is subjected to an external force, within a certain range, its deformation amount is proportional to the stress. Furthermore, the elastic range of the measured fabric can be directly obtained by obtaining the pressure value. During the operation process, assisted by the mechanical components, an external force is continuously applied to one side of the fabric to cause a part of the fabric body to form. The pressure changes generated in real time are known by the relevant components. After reaching the preset range, the external force pushing is stopped, and the test component quickly resets. During the process, the image acquisition component can take pictures of the fabric state in real time to obtain whether the fabric structure breaks when being extruded by the external force. After the test component quickly resets, the fabric rebound rate can be clearly viewed. The two measured data are both stored in the relevant modules of the system for subsequent relevant personnel to view.

[0030] Embodiment 3, as Figure 1 、 Figure 2 and Figure 8 shown, the release clamping mechanism 5 includes two groups of load-bearing frames 501. The two groups of load-bearing frames 501 are both fixedly installed on the top of the upper support plate 2. A group of threaded rods 502 are movably inserted into the inside of each load-bearing frame 501. An outer support arm 503 is fixedly sleeved at one end of each threaded rod 502. A second hollow sleeve 504 is fixedly installed at the end of each outer support arm 503. A cross bar 505 is movably inserted between the inner surface walls of every two opposite second hollow sleeves 504. A guiding roller rod 506 is fixedly sleeved on the outer surface wall of each cross bar 505. A nut 507 is rotatably connected to the outer surface wall of each threaded rod 502.

[0031] The effects achieved by the entire Embodiment 3 are as follows: By presetting the above components, these components can construct a fabric transportation platform, which is used in cooperation with a winding device. The purpose is to ensure that the equipment installed on the multi-station platform will not interfere with the production of fabrics. At the same time, the selected part of the test fabric each time does not need to be manually transferred, and can be assisted by the equipment system and mechanical components, effectively reducing the operation difficulty of the equipment, improving the fabric testing efficiency, optimizing the operation mode, and reducing the labor cost.

[0032] Embodiment 4, as Figure 8 shown, a set of linkage rods 508 are movably inserted into the interior of each load-bearing frame 501. A rolling sleeve 509 is fixedly sleeved on the outer surface wall of each linkage rod 508. An outer support plate 510 is fixedly inserted into the interior of each rolling sleeve 509. A first movable joint assembly 511 is provided at the end of each outer support plate 510. A pressing plate 512 is fixedly installed between the bottoms of every two first movable joint assemblies 511. A set of extension frames 513 are fixedly installed on the outer surface wall of each load-bearing frame 501. A set of second movable joint assemblies 514 are fixedly installed on the outer surface wall of each extension frame 513. A set of third movable joint assemblies 515 are fixedly installed on the outer surface wall of each outer support plate 510. An electric push rod 516 is fixedly inserted into the interior of each second movable joint assembly 514. The shaft ends of each electric push rod 516 are respectively fixedly inserted into the interior of a corresponding third movable joint assembly 515.

[0033] The effects achieved by the entire Embodiment 4 are as follows: Since the equipment main body is installed between the forming and winding equipment, by using the constructed transportation platform and the pulling force generated by the winding equipment on the fabric, the fabric moving on the equipment is always in a taut state. When testing a part of the fabric, the set mechanical components can tightly clamp both ends of the selected fabric, so that this part of the fabric remains in its initial state. The purpose is to ensure that when applying pressure to the fabric subsequently, the fabric at both ends will not be pulled in, affecting the test results and the test efficiency, enabling the production line to return to normal faster, and preventing the output and collection rates from being inconsistent due to excessive accumulation of fabric at one end of the equipment.

[0034] The working principle of the entire equipment is as follows: In the preparation stage, select a suitable installation location, install the equipment main body between the forming machine and the winding machine, with the front end facing the discharge end of the forming machine and the rear end facing the feeding end of the winding machine. Fix the equipment main body by choosing a suitable method according to the site requirements. Connect the external wire to the equipment power supply to provide energy for multiple electrical components inside. With the help of an external device to correct the data of the equipment system module, set the required interval duration for each test, and this instruction is stored and executed by the relevant module.

[0035] During the erection stage, the fabric produced by the forming machine is first manually assisted in laying the fabric on top of the assembly frame 1 and inserted between the two sets of guide rollers 506. The end of the fabric is connected to the winding device, and the position of each outer arm 503 is adjusted to ensure that the guide rollers 506 can contact the corresponding side of the fabric. The nut 507 is twisted to lock the position of each guide roller 506 in turn. After the winding machine is running, the continuously formed fabric can move parallel to the device. The friction force exerted by the two sets of guide rollers 506 on the surface of the fabric makes the fabric entering the device in a straight state.

[0036] During the test phase, when the set test time is about to arrive, the system-related modules can share the signal with the winding machine to quickly stop the winding work. At the same time, each set of electric push rods 516 are synchronously turned on to make the inner shaft extend outward quickly. By utilizing the movable characteristics of the linkage rod 508, the roller sleeve 509, the second movable joint assembly 514 and the cross bar 505, each set of pressing plates 512 is squeezed, and the external force is directly applied to the two ends of the selected part of the cloth. During the process, the workmanship of the forming machine is not affected. After the channel is blocked, the continuously produced fabrics are accumulated at one end of the equipment. , further open each pneumatic component 402, so that its inner axis retracts in the cavity, and utilizes the movable connection of the sliding sleeve 405 and the cooperative slide plate 406 to drive the second associated frame 409 and its connected components to slowly move upward. During the process, the transparent shield 416 and the arc-shaped cover plate 418 gradually contact one side of the fabric. Utilizing the movable connection of the first hollow sleeve 421 and the metal slide rod 422, the arc-shaped cover plate 418 shows a downward pressure trend, driving the pressing buckle 424 to move downward for a distance, and finally making the pressing buckle 424 fully press onto the pressure sensing component 425, and starting There is a pressure value, and as the fabric is pulled upward, the pressure pushed back on the pressure sensor component 425 also increases synchronously. At the same time, the macro camera 413 is in operation. After the fabric is completely wrapped on the transparent cover 416, the internal light will be dim. Then, when the macro camera 413 is turned on, the fill light board 414 is also powered on. The light emitted can face the pressure surface of the fabric to ensure the brightness of the shooting angle of the macro camera 413. The macro camera 413 captures the structural changes of the fabric when it is stretched in real time, and temporarily stores the obtained data. In the relevant modules, the pressure obtained in real time by the pressure sensing component 425 can be shared with the system-related modules. When the set range is reached, the pulling action is stopped, and the pneumatic component 402 is turned on to quickly extend its inner shaft, driving the test component to quickly reset. The fabric that loses external support begins to rebound, and the macro camera 413 is still performing image acquisition to record the fabric rebound process. After a test is completed, each component is reset, the winding machine operates normally, and the processing of the fabric stranded at the front end of the equipment is accelerated, and waits for the next test time to arrive.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
