Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, specifically to a simple testing device for random inspection of textiles. Background Technology

[0002] Textile quality inspection is a crucial step in the textile industry's production process, directly impacting the feel, comfort, durability, and appearance of textiles. Currently, the industry commonly employs manual inspection, where inspectors assess the texture density by visually observing and touching the textiles. This method heavily relies on the inspector's subjective judgment and is easily affected by factors such as personal experience, visual fatigue, and ambient lighting, making it difficult to guarantee accuracy. Furthermore, manual inspection is inefficient and fails to meet the demands of modern industrial production for high-efficiency and precise testing.

[0003] Fabric weight and density are important indicators for measuring the quality of textiles, and the tools and equipment used to measure them are indispensable in the textile industry. Traditional physical measuring tools often measure fabric weight and density separately, which is complex, produces inconsistent data, and has low testing efficiency.

[0004] In recent years, the rapid development of image processing technology has provided new solutions for textile quality inspection. By acquiring fabric images through cameras and utilizing advanced image processing algorithms, it is possible to automatically identify and count the number of warp and weft yarns in the fabric, thereby accurately measuring the warp and weft density. However, processing fabric density through cameras requires specific environmental conditions; chaotic lighting can easily affect the measurement results, leading to poor performance and low accuracy. Furthermore, the cost of specially purchased image processing and recognition equipment is too high, making it uneconomical. Utility Model Content

[0033] like Figure 1 , Figure 4 as well as Figure 5 As shown, this embodiment provides a simple testing device for textile sampling inspection. The testing device includes: a base 1, a cover 2, an electronic weighing device 3, and an image acquisition device 4.

[0034] The base 1 is used to support the electronic weighing device 3 and the cover 2.

[0035] The cover 2 is made of an opaque material that blocks light. The bottom of the cover 2 is an open structure. The cover 2 includes side walls and a top wall. The side walls are provided with closed doors 210 for taking out and putting in fabric samples. The bottom of the side walls of the cover 2 is mounted on the base. The shape of the cover 2 can be set according to the actual situation, such as cylindrical, rectangular, or trapezoidal. The cover 2 achieves isolation between the detection environment and the external environment, realizes the uniformity of the detection environment, and can greatly improve the detection accuracy and precision.

[0036] The electronic weighing device 3 is mounted on the base 1, and the weighing platform 310 of the electronic weighing device 3 is covered inside the cover 2; the shape of the weighing platform 310 can be set according to the actual situation, for example, it can be circular or rectangular.

[0037] The image acquisition device 4 is positioned directly above the weighing platform 310 inside the enclosure 2. The image acquisition device 4 includes a camera 410, a lighting lamp 420, and a data cable (not shown). The camera 410 is mounted on the top wall with its shooting center vertically aligned with the center of the weighing platform 310, capturing images of the fabric surface vertically to ensure no tilt or distortion. The lighting lamp 420 is positioned around the camera 410 to provide a shooting environment inside the enclosure 2, achieving a relatively controllable lighting environment. Both the camera 410 and the lighting lamp 420 are connected to an external computer via the data cable. Image processing of the fabric images acquired by the camera 410 enables automatic identification and counting of the number of warp and weft yarns in the fabric, thereby accurately measuring the warp and weft density or identifying the pattern of the fabric.

[0038] During use, the operator opens the closed door 210 and places the fabric sample flat on the weighing platform 310 inside the cover 2, and then closes the closed door 210. The electronic weighing device 3 can obtain the weight of the fabric sample. The image acquisition device 4 captures the surface image of the sample fabric through the camera 410 under the illumination of the lighting lamp 420, and transmits the acquired surface image to an external computer to calculate the density of the fabric sample.

[0039] Preferably, the electronic weighing device 3 can also be electrically connected to an external computer, which can directly read the measurement data from the electronic weighing device 3.

[0040] Both the lighting fixture 420 and the camera 410 can be controlled by an external computer. The lighting fixture 420 is turned on or off under the control of the external computer; the data cable provides power to the lighting fixture 420 and also transmits control signals. The camera 410 can be controlled to turn on and transmit data via the data cable.

[0041] Specifically, in this embodiment, such as Figure 2 As shown, a human-machine interface panel 5 is provided on one side of the electronic weighing device 3. The human-machine interface panel 5 is used to receive and display the measurement data of the electronic weighing device 3, and to send control commands to the electronic weighing device 3. The human-machine interface panel 5 is the same as that in existing electronic scales, and may be, for example, a combination of a display screen and physical buttons, a touch screen, and a combination of pluggable modules and expansion interfaces.

[0042] Specifically, the human-computer interaction panel 5 comprises a display 510 and an operation panel 520. The display 510 can display device function options, images acquired by the camera 410, and textile recognition results, etc.; the operation panel 520 includes, but is not limited to, directional keys, confirmation keys, return keys, power keys, and necessary shortcut operation keys, so as to control the cursor selection on the display 510 and execute corresponding functions.

[0043] Furthermore, the cover 2 is also provided with at least one handle 220, which is located on the top of the cover 2. In this embodiment, as... Figure 2 As shown, there are two handles 220, which are arranged side by side and parallel to each other on the top of the cover 2.

[0044] Optionally, the cover 2 is made of black plastic. Black objects absorb all wavelengths of visible light and reflect almost no light. The black background creates a high contrast with the subject, highlighting the subject, making edges sharper, details richer, and improving accuracy. Made of plastic, which has a low density, it is easy to handle and install.

[0045] Specifically, the plastic material is polycarbonate (PC) or acrylonitrile-butadiene-styrene copolymer (ABS) with added colorants. Plastic raw materials are low-cost, the processing technology is simple, and production efficiency is high.

[0046] Preferably, the surface of the weighing platform 310 near the camera 410 is provided with coordinate grid lines 320. The coordinate grid lines 320 serve as a visual reference, allowing the user to quickly determine the position where the object needs to be placed on the weighing platform 310, reducing manual alignment errors.

[0047] Optionally, in this embodiment, the number of illumination lamps 420 is four, and the four illumination lamps 420 are evenly arranged around the camera 410. The illumination lamps 420 are LED lamps and have adjustable brightness. The illumination lamps 420 can increase the quality of the captured image by increasing brightness and improve recognition accuracy. Arranging them in a ring can make the light illumination more uniform, avoid shadows, and further improve recognition accuracy and precision.

[0048] Specifically, the sealing door 210 is magnetically sealed to the side wall of the cover 2 for easy closure. In other embodiments, the sealing door 210 is mechanically locked to the side wall of the cover 2.

[0049] Preferably, such as Figure 3 As shown, the base 1 has multiple height-adjustable support feet 110 at its bottom, and a level indicator is provided on the base 1. Specifically, the level indicator can be, for example, a mechanical bubble level, used to determine whether the base is level.

[0050] Optionally, the base 1 has a cavity for housing the electronic weighing device 3; the top surface of the side wall surrounding the cavity of the base 1 has a groove that matches the bottom surface of the side wall of the cover 2. This allows for detachable assembly and facilitates transportation.

[0051] It is understandable that the cavity in the base 1 allows for better placement of the electronic weighing device 3. In other examples, the cavity can be omitted, and the electronic weighing device 3 can be placed directly on the base 1, with a level indicator used to check if the base 1 is level.

[0052] In a preferred embodiment of this utility model, the support foot 110 includes a screw and a rubber pad, used to increase the stability and anti-slip performance of the simple testing equipment for textile sampling inspection. The screw engages with a screw hole on the bottom surface of the base to adjust the distance the screw extends beyond the bottom surface of the base, thereby adjusting the height of the support foot 110. By adjusting the height of the support foot 110, the equipment can be kept level on uneven ground, avoiding detection errors caused by tilting. In other embodiments, the support foot 110 uses a pneumatic or hydraulic telescopic structure to achieve lifting and lowering.

[0053] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model. In addition to the above embodiments, this utility model may have other implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
