Description

Technical Field

[0001] This utility model relates to the field of fabric processing technology, specifically to a general-purpose laser processing equipment for denim fabric. Background Technology

[0002] Denim is a relatively thick, yarn-dyed twill cotton fabric. The warp yarns are dark, usually indigo, while the weft yarns are light, usually light gray or bleached off-white. Denim production involves techniques such as burnishing and distressing, resulting in diverse styles.

[0003] The burnishing process for denim involves using a high-energy laser beam to instantaneously act on the surface of the denim, causing the dye to vaporize and the fibers to melt, forming clear patterns or textures. After engraving, the edges of the pattern are burr-free, washable, and abrasion-resistant, eliminating the need for physical contact to prevent fabric deformation. When the denim enters the laser burnishing equipment, the laser beam acts on the denim surface, causing the surface dyes (such as indigo) and fibers to vaporize instantaneously at high temperatures, generating gaseous organic matter and tiny particles, forming visible white smoke. Excessive burning of the fabric produces incompletely burned carbon black particles and tar. Simultaneously, the denim contains sizing agents and chemical additives (such as formaldehyde resin), which are decomposed by the high temperature of the laser, releasing volatile organic compounds such as formaldehyde and benzene. Thus, in the denim... When denim is pushed into the laser burning equipment, the fabric is uneven, and particles, tar, and organic matter will fall onto the denim. The denim is hot in the laser burning area, and the falling particles easily adhere to the hot area and form a bond with the burning area. The particles also drift to the unburned or already burned areas of the fabric and adhere to the surface, causing the fabric to produce an unpleasant odor and contaminate the burning area, affecting the overall appearance of the denim. Therefore, we propose a general-purpose laser processing equipment for denim. Utility Model Content

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0024] Please see Figure 1-7 This utility model provides a general-purpose denim fabric laser processing equipment, including: a processing equipment frame 1 and a transport equipment frame 2. A laser generator 11 is installed on the top of the processing equipment frame 1. An adjustment seat 12 is installed on one side of the processing equipment frame 1, and a laser tube 13 is installed on the adjustment seat 12. The laser tube 13 is connected to the laser generator 11 by a wire.

[0025] Specifically, the processing equipment frame 2 has a frame structure on top, mainly used for installation and protection, and inspection windows are installed on its sides. The adjustment seat 12 is hinged, and the position of the laser tube 13 can be adjusted by adjusting its position. After the laser emitter 11 emits laser light, because the laser emitter 11 is equipped with a positioning system, the positioning system is a built-in system of the laser emitter itself. The commonly used system is a vision positioning system, which uses a high-resolution industrial camera (CCD / CMOS sensor) to capture the surface features of denim fabric. Combined with the light source system to optimize image quality, the laser can be emitted according to the determined position.

[0026] Furthermore, a feeding roller 4 is installed at one end of the transport equipment frame 2, and a discharging roller 5 is installed at the other end. A transmission component 6 is installed on the transport equipment frame 2 and is connected to the transport mechanism 3. The rotating roller 33 is connected to the transmission component 6, and a discharge ramp 21 is installed on the transport equipment frame 2. Specifically, by placing the fabric on the transport belt 31, the transport belt 31 drives the denim fabric into the processing equipment frame 1. At the same time, the flipping of the feeding roller 4 can flatten the denim fabric as a whole, preventing the denim fabric from entering the processing equipment frame 1 in a wrinkled state.

[0027] Furthermore, a protective area is provided between the feeding roller 4 and the processing equipment frame 1. The protective area consists of two protective absorption plates 7, and the two protective absorption plates 7 are installed outside the transport equipment frame 2 through the adjusting component 9. The protective absorption plates 7 have an absorption surface 71. The two ends of the protective absorption plates 7 are respectively provided with mounting cavities 72, and nitrogen jetting components 8 are installed in the mounting cavities 72. The mounting cavities 72 are provided with nozzles 73 facing the absorption surface 71.

[0028] In this preferred embodiment, the protective absorption plate 7 is a honeycomb activated carbon layer, and the absorption surface 71 is concave.

[0029] Furthermore, the absorption surface 71 is provided with multiple sets of absorption holes 74, and the absorption holes 74 in each layer of the absorption plate are distributed alternately in elliptical and circular shapes.

[0030] This invention features two adjustable absorption plates at the bottom of the laser tube. This allows the laser to be concentrated on the area of ​​the denim fabric that needs to be treated. At the same time, the white smoke particles and compounds generated during the laser burning process can be fully absorbed, thus preventing them from affecting other parts of the denim fabric. This helps maintain the appearance of the denim fabric after burning and reduces the odor and debris generated during the burning process.

[0031] In this preferred embodiment, the lower part of the processing equipment frame 1 is provided with a slot for the passage of the transport equipment frame 2, and the transport equipment frame 2 is equipped with a transport mechanism 3. The transport mechanism 3 includes a transport belt 31 disposed in the transport equipment frame 2, and a rotating shaft 32 is respectively installed at both ends of the transport belt 31. A rotating roller 33 is respectively installed at both ends of the rotating shaft 32, and a drive motor 34 is installed on one of the rotating rollers 33. After the drive motor 34 is started, the drive motor 34 drives the rotating roller 33 to rotate, thereby causing the rotating shaft 32 to rotate. Since the transport belt 31 is installed on two rotating shafts 32, the transport belt 31 can rotate and transport.

[0032] In this preferred embodiment, in order to adjust the position of the two absorbent protective plates 7, the adjusting component 9 includes a mounting plate 91, on which a rotating shaft 92 is provided, and the rotating shaft 92 is rotatably connected to the side wall of the transport equipment frame 2. The mounting plate 91 is provided with an adjusting groove 93, and two connecting plates 94 are provided on the mounting plate 91, and one end of the connecting plate 94 is connected to the protective absorbent plate 7. An adjusting column 95 is installed at the bottom of the connecting plate 94, and the adjusting column 95 passes through the adjusting groove 93 and is connected by a nut. Arc-shaped adjusting plates 97 are provided on both side walls of the transport equipment frame 2, and both ends of the arc-shaped adjusting plates 97 are fixedly connected to the transport equipment frame 2. An adjusting rod 96 is connected to the connecting plate 94, and the adjusting rod 96 is connected to the arc-shaped adjusting plate 97.

[0033] Furthermore, a compression spring 98 is connected between the two connecting plates 94.

[0034] Specifically, after adjusting the two absorption and protective plates 7 to the required angle position, a processing protective area is formed at the bottom of the laser tube 13, thereby effectively isolating the denim processing area from the area that has been burned, preventing the white smoke particles generated during the burning process, as well as the falling and adhesion of other organic matter during the burning process, from producing unpleasant odors and adhering debris on the denim.

[0035] The aforementioned protective absorption plate 7 is a honeycomb activated carbon layer, and the absorption surface 71 is concave. When white smoke particles are generated during the burning process, the jet assembly 8 sprays protective gas along the lower part of the protective absorption plate 7. On the one hand, the particles can adhere to the absorption surface 71. Because the absorption surface 71 is designed to be concave, it is beneficial to ensure that the attached particles are in full contact with the honeycomb activated carbon layer, thereby facilitating the absorption of particles.

[0036] In this preferred embodiment, the jet assembly 8 includes a storage tube 81 installed in the mounting cavity 72. The storage tube 81 is provided with multiple air ports 82, and the air ports 82 are connected to the nozzle 73. A circulation pipe 83 is connected between two storage tubes 81, and a micro pump 84 is installed on the circulation pipe 83.

[0037] The aforementioned jet assembly 8 controls a micro-pump 84 (which uses a motor to drive a diaphragm to reciprocate, compressing or stretching the gas in the pump chamber to create a pressure difference, thus achieving the function of pumping or venting, and has an inlet and outlet gas interface design) to spray out the nitrogen stored in the storage tube 81. The nitrogen content inside the storage tube 81 is replenished by connecting it to an external nitrogen storage tank through a pipeline. After the nitrogen is sprayed out from the lower part of the protective absorption plate 7, the nitrogen can quickly form a structure with the particulate matter and fall onto the concave absorption surface 71, which is conducive to the full contact between the attached particulate matter and the honeycomb activated carbon layer, thus facilitating the absorption of particulate matter.

[0038] In this preferred embodiment, the feeding roller 4 and the unloading roller 5 flatten the fabric. The transmission component 6 includes a drive gear 61 mounted on the rotating roller 33. Mounting frames 22 are respectively mounted at both ends of the transport equipment frame 2, and the two ends of the feeding roller 4 and the unloading roller 5 are rotatably connected to the mounting frames 22. A driven gear 62 that meshes with the drive gear 61 is mounted at one end of the feeding roller 4 and the unloading roller 5. The feeding roller 4 and the unloading roller 5 are curved rollers, and the contact points between the feeding roller 4 and the unloading roller 5 and the fabric are made of flexible material.

[0039] The aforementioned transmission component 6 drives the driven gear 62 under the rotation of the drive gear 61, thereby causing the feed roller 4 and the feed roller 5 to rotate. Since the feed roller 4 and the feed roller 5 are curved rollers and the contact area between the feed roller 4 and the feed roller 5 and the fabric is made of flexible material, it is beneficial to flatten the fabric.

[0040] The basic working principle of this utility model is as follows: First, determine the protection area, that is, determine the two absorption protection plates 7. Loosen the nuts on the outside of the adjusting column 95 and adjust the connecting plate 94 along the mounting plate 91 to adjust the absorption protection plate 7 to the corresponding position. At the same time, in order to increase the stability of the two absorption protection plates 7, adjust them to the corresponding position along the arc-shaped adjusting plate 97 using the adjusting rod 96. Then, fix the nuts to keep the two absorption protection plates 7 stable.

[0041] Simultaneously, the drive motor 34 is activated, causing the conveyor belt 31 to begin moving. The denim fabric to be processed is placed on the conveyor belt 31. The drive gear 61 rotates, driving the driven gear 62, which in turn causes the feed roller 4 and the discharge roller 5 to rotate. Because the feed roller 4 and the discharge roller 5 are curved rollers, and the contact points between them and the fabric are made of flexible material, this facilitates the smoothing of the fabric. When the denim fabric enters the protective area formed by the two absorbent protective plates 7, the laser generator 11 emits a laser beam that acts on the denim fabric through the laser tube 13, creating a burnishing effect. White smoke and other particulate matter generated during the burnishing process float, and nitrogen stored in the storage tube 81 is ejected.

[0042] The nitrogen content inside the storage tube 81 is connected to an external nitrogen storage tank through a pipeline, thereby replenishing the nitrogen inside the storage tube 81. After the nitrogen is sprayed out from the lower part of the protective absorption plate 7, the nitrogen can quickly form a structure with the particulate matter and fall onto the concave absorption surface 71. This facilitates full contact between the attached particulate matter and the honeycomb activated carbon layer, thus facilitating the absorption of particulate matter. This prevents particulate matter and other organic matter from falling onto the untreated and treated areas of the denim fabric, reducing the unpleasant odor and clumps of particles and organic matter on the denim fabric surface caused by the burning process.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
