Description

Technical Field

[0001] The present invention relates to the technical field of fabrics, and in particular to a waterproof and breathable functional fabric production and testing equipment and a testing method thereof. Background Art

[0002] In the production process of functional fabrics, waterproofness and breathability are two crucial performance indicators. Traditional testing methods often rely on manual operations, which are not only inefficient, but also difficult to ensure the accuracy and consistency of test results. Especially for large-scale production, this manual testing method is not only time-consuming and labor-intensive, but also prone to misjudgment due to human factors, thus affecting product quality and the market competitiveness of enterprises.

[0003] In addition, when testing the waterproof performance of fabrics, traditional testing methods usually simply spray water on the surface of the fabric to observe whether there is water seepage. Although this method is intuitive, it cannot quantitatively evaluate the waterproof performance of the fabric, nor can it accurately determine whether the water seepage is caused by problems with the fabric itself or by sewing, splicing and other process links. Similarly, for the detection of breathability, traditional methods often use manual feeling or simple instruments to measure the temperature difference or wind speed changes on both sides of the fabric. This method also has the problem of low accuracy and susceptibility to interference from external factors.

[0004] In addition, in the process of fabric production, in order to remove the moisture inside the fabric, it is usually necessary to go through a drying process. However, traditional drying methods often have the problems of long drying time and high energy consumption, which not only increases production costs, but may also cause the fabric to deform or be damaged at high temperatures. Therefore, how to improve drying efficiency and reduce energy consumption while ensuring the waterproofness and breathability of the fabric has become an urgent problem to be solved in the current field of functional fabric production. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of low efficiency of the detection method in the prior art, unclear effect and low precision in the detection of waterproofness and air permeability, and to propose a waterproof and breathable functional fabric production and its detection equipment and testing method.

[0010] A rectangular box is fixedly connected to an inner wall of one side of the device housing, and a second detection component for detecting the air permeability of the fabric body is arranged inside the rectangular box;

[0011] A same group of squeezing components for squeezing moisture from the fabric body is arranged between the inner walls on both sides of the device shell.

[0012] In one possible design, the water supply assembly includes a water pump fixedly connected to one side of the device housing, the water inlet of the water pump is fixedly connected to a water inlet pipe, one end of the water inlet pipe extends to the interior of the device housing, and the water outlet of the water pump is fixedly connected to a water outlet pipe, one end of the water outlet pipe is fixedly connected to one side of the water box.

[0013] In a possible design, the first detection component includes a plurality of hollow metal sheets integrally formed on one side of the rectangular hole, and a plurality of circular holes are formed at the bottom of the hollow metal sheets.

[0014] In one possible design, the drive assembly includes an L-shaped plate fixedly connected to the top of the device housing, a servo motor is fixedly connected to the top of the L-shaped plate, the output shaft of the servo motor is fixedly connected to the input shaft of the heater, and an incomplete gear is fixedly sleeved on the outer wall of the output shaft of the servo motor.

[0015] In a possible design, the second detection component includes a sliding plate that is slidably connected between the inner walls of both sides of the rectangular box, a limiting hole is opened on one side of the device shell, a trapezoidal block is slidably penetrated inside the limiting hole, the inclined surface of the trapezoidal block is used in conjunction with the sliding plate, one end of the trapezoidal block is fixedly connected to a side plate, and two symmetrically arranged tension springs are fixedly connected between one side of the side plate and one side of the device shell.

[0016] In a possible design, the extrusion assembly includes two symmetrically arranged strip holes opened on the top of the device shell, a vertical plate is slidably penetrated inside the strip hole, a spring is fixedly connected between one side of the vertical plate and an inner wall of one side of the strip hole, a vertical hole is opened inside the vertical plate, two symmetrically arranged circular shafts are slidably penetrated inside the vertical hole, a roller is rotatably connected between the two circular shafts located at the same height, two symmetrically arranged strip grooves are opened on the inner walls on both sides of the device shell, and one end of the circular shaft extends to the inside of the strip groove.

[0017] In a possible design, a same cross bar is fixedly connected between the two vertical plates, a connecting rod is fixedly connected to one side of the cross bar, a rack is fixedly connected to one end of the connecting rod, and the rack is meshed with an incomplete gear.

[0018] In a possible design, legs are fixedly connected to both sides of the bottom of the device housing.

[0019] A testing method for waterproof and breathable functional fabrics, specifically comprising the following steps:

[0020] S1. Waterproof performance test: The fabric body passes through the device through a rectangular hole, and the water pump is started to extract water inside the device and spray it onto the fabric surface through the nozzle. If the fabric is waterproof, the water slides down along the fixed side plate. If it is not waterproof, the water drops on the hollow metal sheet and an alarm sounds.

[0021] S2. Air permeability test: The servo motor drives the heater to blow hot air to the surface of the fabric. The hot air penetrates the fabric and acts on the sliding plate. The air permeability of the fabric is judged according to the displacement of the sliding plate, the trapezoidal block and the tension spring. When the air permeability is unqualified, the trapezoidal block enters the limit hole as an indication.

[0022] S3. Water squeezing and discharge: The servo motor drives the incomplete gear to rotate at the same time, driving the rack, connecting rod, cross bar and vertical plate to move, so that the drum squeezes the fabric, accelerates the water discharge, and reduces the drying time. After the incomplete gear is separated from the rack, the spring resets and is ready for the next use.

[0023] In the present application, when in use, the fabric body passes through the interior of the device housing through two rectangular holes and is rolled up by the winder. At this time, the water pump is started, and the water pump draws water from the interior of the device housing through the water inlet pipe, and then sends it to the interior of the water box through the water outlet pipe, and then sprays it onto the surface of the fabric body through multiple nozzles;

[0024] At this time, the waterproof performance of the fabric body can be tested. If the waterproof performance of the fabric body is qualified, the clean water will slide down along the top two sides of the fixed side plate through the surface of the fabric body. If the waterproof performance of the fabric body is unqualified, the leaked water will drip on the surface of the hollow metal sheet. Since the hollow metal sheet is hollow and has multiple round holes at the bottom, it will make a crisp sound to remind the staff. At the same time, since the hollow metal sheet is tilted, it is convenient for sewage to slide down; the mounting block is set inside one of the rectangular holes, which can facilitate the sound to be transmitted;

[0025] When the fabric body is being transmitted, the servo motor is started, and the servo motor provides power for the heater, which continuously blows hot air to the surface of the fabric body, and the air permeability of the fabric body can be detected. Under normal circumstances, the hot air can help dry the surface of the fabric body, and at the same time, the hot air can pass through the fabric body and blow it to the surface of the sliding plate. The sliding plate moves down, and the sliding plate pushes the trapezoidal block to move horizontally. The trapezoidal block drives the side plate to move horizontally, so that the tension spring is always in a stretched state. If the air permeability of the fabric body is unqualified, the trapezoidal block will enter the inside of the limit hole at this time, which can be used to remind the staff;

[0026] When the servo motor is started, the output shaft of the servo motor can drive the incomplete gear to rotate, the incomplete gear drives the rack to move laterally, the rack drives the connecting rod to move laterally, the connecting rod drives the cross bar to move laterally, the cross bar drives the two vertical plates to move laterally, the vertical plates squeeze the springs and drive the two round shafts to move laterally, the round shafts drive the two rollers to move laterally. Since the round shafts are always located inside the strip grooves, the two round shafts will gradually approach each other, and then the two rollers can squeeze the surface of the fabric body to help drain the internal moisture and reduce the subsequent drying time. When the incomplete gear is disengaged from the rack, the vertical plate returns to its original position under the elastic force of the spring, which is convenient for next use.

[0027] Beneficial effects: Automated detection and feedback mechanism: This application realizes automated detection of fabric waterproof and breathable properties by integrating components such as water pumps, nozzles, hollow metal sheets and servo motors. Once it is detected that the fabric is unqualified for waterproofness or breathability, the system can immediately remind the staff through sound prompts (hollow metal sheets make sounds) or physical displacement (trapezoidal blocks enter the limit holes), greatly improving detection efficiency and accuracy.

[0028] Intelligent adjustment and energy-saving optimization: Using servo motors to drive the heater and drum system can not only intelligently adjust the hot air supply and fabric extrusion intensity according to the detection requirements, but also dynamically adjust the drum spacing during the detection process, effectively promoting the discharge of moisture inside the fabric, reducing drying time, and thus saving energy.

[0029] Structural design and convenient maintenance: The design takes into account the convenience of sound transmission (through mounting blocks and rectangular holes), as well as the automatic reset function of mechanical parts (such as incomplete gears and racks, springs and vertical plates), ensuring stable operation and easy maintenance of the equipment. At the same time, the inclined hollow metal sheet and strip groove design facilitate the natural sliding of sewage and excess water, reducing the workload of cleaning.

[0030] Multifunctional integration and efficient utilization: This device integrates three functions of waterproof testing, breathability testing and moisture extrusion and discharge, realizing a comprehensive evaluation of fabric performance, improving the comprehensive utilization rate of testing equipment and reducing enterprise costs.
