Description

Technical Field

[0001] The present invention relates to the technical field of cloth performance detection, and more specifically, to a blanket cloth defect detection device and a detection method. Background Art

[0002] Blanket fabric defect detection is an indispensable part of ensuring its product quality. The process covers a wide range of detailed inspections from appearance defects, dimensional accuracy to physical properties and chemical characteristics. In the field of physical properties testing, it is particularly complex. It relies on a variety of professional equipment such as tensile machines, friction testers and pressure testing devices, so it often needs to combine the dual advantages of manual experience and automation technology.

[0003] Although the traditional manual inspection method is a bit quaint, it shows its unique value in small batches or low-precision scenarios. With keen eyesight or with the help of a magnifying glass, inspectors can intuitively find and mark significant defects on the surface of blankets. However, with the rapid development of automation technology, image recognition and machine learning algorithms have become the mainstay of modern inspection systems. They can not only instantly capture and evaluate the color uniformity and texture clarity of blankets, but also accurately identify and classify various defects, greatly improving inspection efficiency and accuracy.

[0004] However, in the complex field of physical property testing, even the most advanced automation technology needs to work closely with manpower. Various testing items require frequent switching of different types of equipment, which not only makes the testing process cumbersome and lengthy, but also tests the operator's proficiency in the operation skills of multiple equipment. In addition, if the switching between equipment is not handled properly or the calibration is deviated, new error sources may be introduced, which will affect the accuracy of the test data and ultimately increase the time cost and human resource consumption. In view of this, we propose a blanket fabric defect detection device and detection method. Summary of the invention

[0028] A detection method for a blanket fabric defect detection device comprises the following detection steps:

[0029] S1. Install the blanket fabric to be tested on the testing table, adjust the device according to the test items to be tested, and after the adjustment is completed, move the testing mechanism as a whole down to the top of the fabric through the height adjuster, then start the motor, and select the forward or reverse motor according to the test items;

[0030] S2, before the driving motor drives the driving component to rotate forward, the limiting cylinder needs to be pulled down so that the first shell component and the second shell component are docked. The motor is in high-speed operation. At this time, the motor will drive the transmission component to operate through the driving component, so that the transmission component rotates rapidly and the second shell component as a whole will rotate synchronously. At this time, a large amount of gas will be discharged downward along the second shell component, so that the gas passes through the fabric and is discharged into the pressure detector, thereby detecting the air permeability of the fabric. Subsequently, the first shell component is reset and the motor is driven so that the motor drives the driving component to reverse. At this time, the motor is in low-speed operation, and the electric push rod will also start synchronously with the reverse rotation of the motor to complete the connection between the driving component and the second shell component. At this time, the second shell component will rotate eccentrically with the driving component, so that the docking component rubs on the surface of the fabric, thereby completing the wear resistance test of the fabric, so that the device only needs to make corresponding adjustments to the first shell component and control the motor to rotate forward or reverse to complete the air permeability test and wear resistance test of the fabric;

[0031] S2.1. When the motor rotates forward, the motor drives the installation cylinder to rotate through the driving rod, the transmission wheel and the transmission belt, so that the exhaust fan blades outside the installation cylinder quickly extract the air above the second shell and discharge it to the bottom of the second shell. Since the second shell is tightly attached to the fabric through the first air inlet cylinder and the second air inlet cylinder, the gas is directly blown to the surface of the fabric. At this time, the gas will pass through the fabric and be directly discharged on the surface of the pressure detector, so that the air permeability of the fabric can be directly detected through the pressure detector;

[0032] S2.2, when the motor reverses, the electric push rod starts and inserts the card block into the card slot. At this time, the second housing as a whole rotates in a circle with the driving rod. At this time, the friction cylinder will rub against the fabric, and during the rotation of the second housing, the transmission gear will also revolve in the first housing. At this time, the transmission gear will rotate due to contact with the gear block, so that the first shaft drives the three driven wheels to rotate synchronously through the driving wheel, thereby extracting the gas below;

[0033] S3. When the exhaust fan blades rotate to discharge gas downward, a large amount of gas squeezes the sealing plate, causing the sealing plate to move down into the second air inlet cylinder. At this time, the gas will be discharged along the gap between the sealing plate and the second air inlet cylinder to ensure the stability of the gas during discharge. When the intake fan blades extract gas, the sealing plate will move upward, causing the gas below to move up along the gap between the sealing plate and the first air inlet cylinder. At this time, the hair scraps dropped from the cloth during friction will also enter the first air inlet cylinder along with the air flow.

[0034] Compared with the prior art, the present invention has the following beneficial effects:

[0035] 1. The present invention designs a driving component, a second housing component and a transmission component. When the driving motor drives the driving component to rotate forward, the motor drives the transmission component to operate through the driving component, so that the gas passes through the fabric and is discharged into the pressure detector, thereby detecting the air permeability of the fabric. When the motor drives the driving component to reverse, the electric push rod will also be started synchronously with the reverse rotation of the motor to complete the connection between the driving component and the second housing component, so that the device only needs to make corresponding adjustments to the first housing component and control the motor to rotate forward or reverse to complete the air permeability test and wear resistance test of the fabric. By reducing the way of cooperating with multiple devices to detect the fabric, on the one hand, it can effectively reduce the errors occurring in the process of switching equipment, thereby improving the accuracy of the detection data. On the other hand, since the use of multiple devices is reduced and a large number of unnecessary equipment use processes are deleted, the difficulty of using the device is reduced, thereby saving a lot of time production and human resources.

[0036] 2. The present invention also designs a transmission component and a second shell component. When the motor rotates forward, the motor will drive the installation cylinder to rotate through the driving rod, the transmission wheel and the transmission belt, so that the gas will be blown directly to the surface of the fabric. At this time, the gas will pass through the fabric and be directly discharged on the surface of the pressure detector, so that the air permeability of the fabric can be directly detected by the pressure detector. The connecting frame and the second shell are in a clamping state, so that when the installation cylinder rotates, the second air inlet cylinder will fix the first air inlet cylinder and the second shell through the friction force when squeezing the fabric and the detection table, thereby avoiding excessive friction on the fabric. At the same time, it can prevent gas leakage, thereby ensuring the accuracy of the fabric permeability detection data.

[0037] 3. The present invention also designs a docking assembly and a sealing assembly. When the motor reverses, the electric push rod starts and inserts the card block into the card slot, and the transmission gear also revolves in the first housing, so that the first rotating shaft synchronously drives the three driven wheels to rotate through the driving wheel, thereby extracting the gas below, so that the device can quickly switch the use state according to the detection item when in use, and when the cloth is rubbed by the friction cylinder, the air flow rate on the surface of the cloth can be accelerated by extracting gas, thereby accelerating the heat dissipation of the cloth, avoiding the spontaneous combustion of the cloth due to overheating during use, and further ensuring the safety during detection and the accuracy of the detection data.

[0066] Working principle: This embodiment provides a blanket fabric defect detection device and detection method. When in use, the blanket fabric to be detected is installed above the detection table 105, and the device is adjusted according to the items to be detected. After the adjustment is completed, the detection mechanism 2 can be moved down to the top of the fabric through the height adjuster 102, and then the motor 202 is started, and the forward or reverse rotation of the motor 202 is selected according to the detection item;

[0067] Before the driving motor 202 drives the driving assembly 204 to rotate forward, the limiting cylinder 2033 needs to be pulled down so that the first shell assembly 203 and the second shell assembly 206 are docked. The motor 202 is in a high-speed operation state. At this time, the motor 202 drives the transmission assembly 205 to operate through the driving assembly 204, so that the transmission assembly 205 rotates rapidly while the second shell assembly 206 rotates synchronously as a whole. At this time, a large amount of gas will be discharged downward along the second shell assembly 206, so that the gas passes through the fabric and is discharged into the pressure detector 106, thereby detecting the air permeability of the fabric. Then the first shell assembly 206 is 203 resets and drives the motor 202 so that the motor 202 drives the driving component 204 to reverse. At this time, the motor 202 is in a low-speed running state, and the electric push rod 2043 will also start synchronously with the reverse rotation of the motor 202 to complete the connection between the driving component 204 and the second housing component 206. At this time, the second housing component 206 will rotate eccentrically with the driving component 204, so that the docking component 208 rubs on the surface of the fabric, thereby completing the wear resistance test of the fabric, so that the device only needs to make corresponding adjustments to the first housing component 203 and then control the motor 202 to rotate forward or reverse to complete the air permeability test and wear resistance test of the fabric;

[0068] When the motor 202 rotates forward, the motor 202 drives the installation cylinder 2055 to rotate through the driving rod 2041, the transmission wheel 2045 and the transmission belt 2046, so that the exhaust fan blades 2056 outside the installation cylinder 2055 quickly extract the air above the second shell 2061 and discharge it to the bottom of the second shell 2061. Since the second shell 2061 is closely attached to the cloth through the first air inlet cylinder 2081 and the second air inlet cylinder 2083, the gas is directly blown to the surface of the cloth. At this time, the gas will pass through the cloth and be directly discharged on the surface of the pressure detector 106, so that the air permeability of the cloth can be directly detected by the pressure detector 106.

[0069] When the motor 202 rotates in reverse, the electric push rod 2043 starts and inserts the card block 2044 into the card slot 2063. At this time, the second housing 2061 rotates as a whole with the driving rod 2041 as a circle. At this time, the friction cylinder 2084 will rub against the cloth, and during the rotation of the second housing 2061, the transmission gear 2053 will also revolve in the first housing 2031. At this time, the transmission gear 2053 will rotate due to contact with the gear block 2035, so that the first rotating shaft 2052 drives the three driven wheels 2074 to rotate synchronously through the driving wheel 2057, thereby extracting the gas below;

[0070] When the exhaust fan blades 2056 rotate to discharge gas downward, a large amount of gas squeezes the sealing plate 2095, causing the sealing plate 2095 to move down into the second air inlet cylinder 2083. At this time, the gas will be discharged along the gap between the sealing plate 2095 and the second air inlet cylinder 2083, ensuring the stability of the gas during discharge. When the air inlet fan blades 2075 extract the gas, the sealing plate 2095 will move upward, causing the gas below to move up along the gap between the sealing plate 2095 and the first air inlet cylinder 2081. At this time, the hair scraps dropped from the cloth during friction will also enter the first air inlet cylinder 2081 along with the air flow.
