Description

Technical Field

[0001] This utility model relates to the field of fabric inspection technology, specifically a fabric missing needle defect detection device. Background Technology

[0002] Missed needle defects are a common problem in fabric production, affecting fabric quality and appearance and reducing product market competitiveness. Traditional methods for detecting missed needle defects rely mainly on manual visual inspection. This method is not only inefficient but also susceptible to subjective factors such as fatigue and lack of concentration from the inspectors, leading to frequent missed detections. With the continuous expansion of fabric production scale and increasingly stringent product quality requirements, there is an urgent need for a highly efficient and accurate device for detecting missed needle defects. Utility Model Content

[0003] The purpose of this invention is to provide a fabric missing needle defect detection device to solve the problems of low efficiency and easy to miss detection in existing detection methods.

[0004] A fabric skipped needle defect detection device includes a support mechanism and a flipping mechanism. The support mechanism includes a support leg at the bottom and a support platform mounted on the support leg. The flipping mechanism is disposed in contact with the upper surface of the support platform. A light-transmitting plate is mounted on the flipping mechanism. The fabric to be detected is placed on the light-transmitting plate. A light source is mounted on the support platform to provide illumination required for fabric detection.

[0005] As a preferred embodiment of this utility model, the flipping mechanism includes an outer frame, which is rotatably connected to the support platform. A support frame is fixedly installed at the middle position of the outer frame. The support frame is used to place the light-transmitting plate. An assembly groove is provided on the rear side of the support frame for clamping the light-transmitting plate.

[0006] As a preferred embodiment of this utility model, the light source part includes a lamp tube, a lamp trough, and a switch. The lamp trough is located in the middle of the support platform. The lamp tube is connected to an external power source and is installed longitudinally at equal intervals in the lamp trough. The switch is installed on the front side of the support leg and is used to control the lamp tube.

[0007] As a preferred embodiment of this utility model, a baffle is vertically installed on the front side of the support platform. The baffle is used to limit the position of the light-transmitting plate and prevent it from shifting.

[0008] As a preferred embodiment of this utility model, an arc-shaped opening groove is provided in the middle of the baffle. The arc-shaped opening groove is used to facilitate the lifting of the flipping mechanism. The flipping mechanism and the arc-shaped opening groove facilitate the replacement of the light-transmitting plate and the lamp tube, and facilitate maintenance.

[0009] As a preferred embodiment of this utility model, the light-transmitting plate is made of tempered glass with a frosted lower surface. Its upper surface is smooth, allowing the fabric to move smoothly and facilitating inspection. The frosted lower surface can prevent the light source from shining directly into the eyes, making it easy for manual observation and inspection. In addition, it has high strength and is wear-resistant.

[0010] By adopting the above technical solution, this utility model has the following beneficial effects:

[0011] This invention, through the setting of a flipping mechanism and a reasonable light source layout, makes the detection process more convenient, allowing operators to quickly inspect fabrics. Compared with traditional manual inspection methods, it greatly improves inspection efficiency and enhances inspection accuracy. The layout of the lamps and the special design of the light-transmitting plate enable operators to observe the fabric texture more clearly, reducing the occurrence of missed detections and improving inspection accuracy. The arc-shaped opening groove design on the flipping mechanism and the baffle facilitates the replacement and maintenance of the light-transmitting plate and lamps, reducing the maintenance cost and difficulty of the equipment.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Example 1

[0019] like Figures 1 to 4 As shown, a specific embodiment of the fabric skipped needle defect detection device of this utility model includes:

[0020] Support mechanism: The support mechanism includes the bottom support leg 1 and the support platform 9 mounted on the support leg 1; the support leg 1 plays a role in stabilizing and supporting the entire device, ensuring that the device will not shake during the testing process; the support platform 9 provides the mounting base for the flipping mechanism 4 and other components, and its size and material can be selected according to the actual use requirements. Generally, a sturdy and flat material, such as metal or high-strength plastic, is selected.

[0021] Flipping mechanism 4: The flipping mechanism 4 is set to fit against the upper surface of the support table 9, and a light-transmitting plate 5 is installed on it; the flipping mechanism 4 includes an outer frame 14, which is rotatably connected to the support table 9, and this connection method allows the flipping mechanism 4 to flip flexibly; a support frame 12 is fixedly installed in the middle of the outer frame 14, and the support frame 12 is used to place the light-transmitting plate 5. An assembly groove 13 is opened on the rear side of the support frame 12, and the light-transmitting plate 5 can be firmly clamped on the support frame 12 through the assembly groove 13 to prevent it from moving during the inspection process;

[0022] Light source component: The light source component is installed on the support platform 9. The light source component includes lamp tube 11, lamp trough 10 and switch 8. The lamp trough 10 is opened in the middle of the support platform 9. The lamp tube 11 is connected to an external power supply and is installed longitudinally at equal intervals in the lamp trough 10. The switch 8 is installed on the front side of the support leg 1 to facilitate the operator to control the opening and closing of the lamp tube 11.

[0023] Other components: A baffle 6 is vertically installed on the front side of the support platform 9. The baffle 6 is used to limit the light-transmitting plate 5 and prevent it from shifting. An arc-shaped opening groove 7 is provided in the middle of the baffle 6 to facilitate the lifting and flipping mechanism 4, making it easy to replace the light-transmitting plate 5 and the lamp tube 11 and to perform device maintenance.

[0024] Preferably, the light-transmitting plate 5 is made of tempered glass with a frosted lower surface; it has high strength and wear resistance, and the upper surface is smooth, which can ensure that the fabric moves smoothly on its surface and is convenient for inspection; the frosted lower surface can prevent the light source from shining directly into the eyes, protecting the operator's eyes, and also facilitates manual observation and inspection.

[0025] The working principle of this utility model is as follows: When the switch 8 is turned on, the lamp tube 11 lights up. The fabric 2 to be tested is placed on the light-transmitting plate 5. The operator uses the pressure plate 3 (the pressure plate 3 consists of a transparent base plate and a handle, which is a commonly used tool in the industry, so it will not be described in detail) to flatten the fabric, ensuring that the fabric surface is flat and avoiding wrinkles from affecting the test results. Then, the fabric on the light-transmitting plate 5 is observed, and the presence of missing needle defects is detected by observing the light passing through the fabric. Since the light-transmitting plate 5 is made of tempered glass with a frosted lower surface, the light is more uniform and softer after being scattered, making it easier for the operator to clearly observe the texture of the fabric and improving the accuracy of the test.

[0026] Maintenance and Replacement: When it is necessary to replace the light-transmitting plate 5 or the lamp tube 11, the operator can pull up the flipping mechanism 4 through the arc-shaped opening slot 7 in the middle of the baffle 6. After the flipping mechanism 4 is opened, the old light-transmitting plate 5 can be easily pulled out for replacement. At the same time, the lamp tube 11 in the lamp trough 10 can also be inspected and replaced. After the replacement is completed, the flipping mechanism 4 is reset and the testing work can continue. Maintenance is quick and convenient.

[0027] All components mentioned in this article are general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods, so they will not be described in detail here.

[0028] While the specific embodiments of this utility model have been described in detail above, this utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this utility model. Modifications or variations that do not involve creative labor are still within the protection scope of this utility model.
