Description

Technical Field

[0001] This utility model relates to the field of fabric inspection technology, specifically to a double-sided fabric inspection machine. Background Technology

[0002] In textile production, after the weaving process is completed, the fabric must undergo a rigorous inspection process before leaving the factory, known as "fabric inspection." This process aims to detect various defects on the fabric surface, such as broken warp and weft threads, holes, stains, color differences, and weft skew. It is a key step in controlling textile quality, improving product grade, and enhancing commercial value.

[0003] Currently, the most widely used fabric inspection method in the industry is still semi-automated manual inspection. The process involves placing the roll of fabric onto an inspection machine, which unfolds and conveys the fabric at a constant speed through an inspection area with adequate lighting. This area is typically equipped with uniformly bright, glare-free flat lights to provide standardized illumination. Inspection workers observe the moving fabric in this area, identifying and marking various defects in real time.

[0004] However, with the increasing demands for textile quality, especially in high-end apparel and home furnishing fabrics, inspecting only one surface of the fabric is no longer sufficient. Many defects, such as minor snags, color differences between the two sides, and stains on the back, are difficult to detect from just one side. A thorough inspection of both sides of the fabric is necessary to ensure no defects are overlooked. Existing conventional fabric inspection machines are typically designed to effectively inspect only one surface of the fabric. For double-sided inspection, operators must unload the entire roll of fabric from the machine after the first inspection, reload it, and restart the machine for a second inspection. This process has significant drawbacks: firstly, the repetitive loading, unloading, turning, and handling operations greatly increase the operator's workload; secondly, the two loading and restarting processes consume a significant amount of time, leading to low overall fabric inspection efficiency and becoming a bottleneck for increasing production capacity; finally, the manual turning and handling processes pose a potential risk of secondary contamination or mechanical damage to the fabric surface, potentially introducing new quality problems. Utility Model Content

[0005] To address the aforementioned technical shortcomings, this invention provides a double-sided fabric inspection machine that inspects both sides of the fabric at once, reducing the number of loading and unloading operations and improving inspection efficiency.

[0006] This utility model discloses a double-sided fabric inspection machine, including a base plate. A winding device is located at one end of the base plate, and an observation platform is located at the other end. Mounting seats are vertically arranged on both sides of the base plate between the winding device and the observation platform. Between the mounting seats, from bottom to top, are a winding device, a first pressure roller, a first drum, a second drum, a second pressure roller, and a guide roller. The first and second drums are transparent yet sealed, filled with a colloidal solution. The first pressure roller presses against the underside of the first drum, and the second pressure roller presses against the upper side of the second drum. An arc-shaped mounting bracket is located on the side of the first drum closest to the observation platform. The mounting plates are arranged as follows: the central axis of the first arc-shaped mounting plate coincides with the central axis of the first roller; a first light strip is evenly arranged on the inner side of the first arc-shaped mounting plate, with a gap between the first light strip and the first roller; a second arc-shaped mounting plate is installed on the side of the second roller closest to the winding device, with the central axis of the second arc-shaped mounting plate coincides with the central axis of the second roller; a second light strip is evenly arranged on the inner side of the second arc-shaped mounting plate, with a gap between the second light strip and the second roller; the first and second arc-shaped mounting plates are fixed to the mounting base, and a drive motor for driving the first and second rollers to rotate is installed on the mounting base.

[0007] In use, the fabric released by the unwinding device passes between the first pressure roller and the first drum and is then wound around the side of the first drum away from the first arc-shaped mounting plate. The fabric is then wound upwards around the side of the second drum away from the second arc-shaped mounting plate, passes between the second pressure roller and the second drum, and finally passes around the guide roller before being wound up by the winding device. During fabric inspection, the first and second light strips are turned on, and the colloidal solution inside the first and second drums scatters the light, allowing the light to evenly illuminate the fabric that is in contact with the first and second drums. Workers between the winding device and the first drum inspect the fabric on the first drum, while workers on the observation platform inspect the fabric on the second drum, thus achieving simultaneous inspection of both sides of the fabric.

[0008] Furthermore, to increase light scattering, the inner surfaces of rollers one and two are roughened.

[0009] Furthermore, in order to increase light scattering and friction, the outer surfaces of rollers one and two are roughened.

[0010] The double-sided fabric inspection machine obtained by this utility model has the following advantages: by filling the inside of the first and second rollers with a colloidal solution, and with the rough design of the inner and outer surfaces of the first and second rollers, multiple scattering effects are achieved, generating a uniform and soft light source, which improves the visibility and detection accuracy of defects on both sides of the fabric; at the same time, the arrangement of the first and second rollers enables simultaneous inspection of both sides of the fabric, which greatly improves the efficiency of fabric inspection.

[0014] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0015] Example 1:

[0016] like Figure 1 , 2 As shown in Figure 3, this utility model discloses a double-sided fabric inspection machine, including a base plate 1. A winding device 5 is provided at one end of the base plate 1, and an observation platform 2 is provided at the other end of the base plate 1. Mounting seats 3 are vertically arranged on both sides of the base plate 1 between the winding device 5 and the observation platform 2. Between the mounting seats 3, a winding device 6, a first pressure roller 7, a first roller 9, a second roller 10, a second pressure roller 12, and a guide roller 13 are arranged rotatably from bottom to top. The first roller 9 and the second roller 10 are transparent and sealed. The inner and outer surfaces of the first roller 9 and the second roller 10 are rough. The first roller 9 and the second roller 10 are filled with a colloidal solution. The first pressure roller 7 presses on the lower side of the first roller 9, and the second pressure roller 12 presses on the upper side of the second roller 10. The first roller 9 is close to the observation platform 2. On the side of the first roller 10, a first arc-shaped mounting plate 8 is provided. The central axis of the first arc-shaped mounting plate 8 coincides with the central axis of the first roller 9. A first light strip 15 is evenly arranged on the inner side of the first arc-shaped mounting plate 8. A gap is left between the first light strip 15 and the first roller 9. On the side of the second roller 10 near the winding device 5, a second arc-shaped mounting plate 11 is provided. The central axis of the second arc-shaped mounting plate 11 coincides with the central axis of the second roller 10. A second light strip 16 is evenly arranged on the inner side of the second arc-shaped mounting plate 11. A gap is left between the second light strip 16 and the second roller 10. The first arc-shaped mounting plate 8 and the second arc-shaped mounting plate 11 are fixed to the mounting base 3. A drive motor 4 for driving the first roller 9 and the second roller 10 to rotate is provided on the mounting base 3.

[0017] When the above technical solution is used, the fabric 14 released by the unwinding device 6 passes between the first pressure roller 7 and the first roller 9 and is wrapped around the side of the first roller 9 away from the first arc-shaped mounting plate 8. Then the fabric 14 is wrapped upwards around the side of the second roller 10 away from the second arc-shaped mounting plate 11, then passes between the second pressure roller 12 and the second roller 10, and finally passes around the guide roller 13 and is wound up by the winding device 5. When inspecting the fabric, the first light strip 15 and the second light strip 16 are turned on. The colloidal solution in the first roller 9 and the second roller 10 scatters the light so that the light can evenly illuminate the fabric 14 that is in contact with the first roller 9 and the second roller 10. The worker between the winding device 5 and the first roller 9 inspects the fabric 14 on the first roller 9, and the worker on the observation platform 2 inspects the fabric 14 on the second roller 10, thereby realizing the simultaneous inspection of both sides of the fabric 14.
