Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic cloth processing, in particular to an ultrasonic cloth composite welding and cutting device. Background Art

[0002] As an advanced fabric processing technology, ultrasonic composite fabric welding and cutting device technology has been widely used in modern industrial production. It uses the high-frequency vibration characteristics of ultrasound to cause intense friction and thermal effects on the fabric at the welding site, thereby achieving rapid welding and precise cutting of the fabric.

[0003] Compared with traditional fabric processing technology, ultrasonic fabric composite welding and cutting device technology has many significant advantages. For example, it can greatly improve production efficiency, reduce processing time and cost, and at the same time ensure the quality and aesthetics of the fabric. Therefore, this technology has been widely used in clothing, textiles, automotive interiors and other fields, and has become one of the important technologies in the fabric processing industry.

[0004] The existing slitting knife and welding assembly are divided into two parts, which take up a lot of space and require a larger installation range for the equipment. This is because the slitting knife and welding assembly need to be installed in different positions, which increases the overall size of the equipment. In addition, since the slitting knife and welding assembly need to be adjusted and maintained separately, this also increases the maintenance cost of the equipment. The slitting knife and welding assembly are designed separately to improve the flexibility and maintainability of the equipment. However, this design also leads to an increase in the overall size of the equipment and an increase in maintenance costs.

[0005] The welding length is fixed at one time. No matter how wide the fabric is, the entire welding mold is fixed and cannot be disassembled. The volume of each mold of a large machine is relatively large. If a part of it is damaged, the repair process and cost of disassembly and replacement are relatively high. This is because the welding mold is a whole and cannot be adjusted according to the width of the fabric. In addition, due to the large volume of the welding mold, if a part of it is damaged, the entire mold needs to be disassembled for repair, which increases the cost and time of repair. The welding mold cannot be disassembled to ensure the quality and stability of welding. However, this design also leads to reduced flexibility of the mold and increased maintenance costs.

[0006] In summary, existing ultrasonic composite fabric welding and cutting devices suffer from issues such as the separate design of the slitting blade and welding assembly, which results in a large installation area, and the inability to disassemble the welding mold, resulting in high maintenance costs. These issues limit the further application and development of this technology, necessitating improvements and optimization to enhance its performance and reliability. Utility Model Content

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] See also Figures 1 to 3 The utility model provides a technical solution: an ultrasonic cloth composite welding and cutting device, comprising a workbench 1, a width-opening roller, a welding pressure roller and a cloth-pulling pressure roller, wherein the width-opening roller, the welding pressure roller and the cloth-pulling pressure roller are sequentially mounted on the same side of the workbench 1, and are used to adjust the flatness of the cloth so that it can smoothly pass through the subsequent welding and slitting processes; a plurality of ultrasonic welding and cutting mechanisms 200 arranged at equal intervals are mounted on the workbench 1, and are used to generate ultrasonic vibrations to weld multiple layers of cloth together; the welding pressure roller is used to flatten the welded cloth to make its surface smoother; the cloth-pulling pressure roller is used to pull the cloth so that it can smoothly pass through the ultrasonic welding and cutting mechanism 200 for cutting, so as to divide the welded cloth into sections according to the required width; and at the same time, the length of the cloth is measured by the ultrasonic welding and cutting mechanism 200 to control the welding and slitting lengths;

[0025] Through the mutual cooperation between the ultrasonic welding and cutting mechanisms 200 on the workbench 1 and the newly added striping structure, not only the tedious steps of secondary cutting according to width requirements after the fabric processing is completed are reduced, thereby improving work efficiency, but also the space occupied by the equipment is significantly reduced. Under the same working environment, the equipment can be arranged more flexibly, saving production space. In addition, the previous overall welding mold is split into multiple groups, making the power distribution more reasonable, thereby improving the welding effect and ensuring the stability and reliability of the welding quality. When a part of the mold is damaged, only the corresponding module needs to be replaced without disassembling the entire mold, which greatly reduces maintenance time and cost.

[0026] The ultrasonic welding and cutting mechanism 200 in this embodiment not only reduces the tedious step of secondary cutting according to width requirements after fabric processing is completed, thereby improving work efficiency, but also significantly reduces the space occupied by the equipment.

[0027] like Figure 1 、 Figure 2 and Figure 3As shown, the ultrasonic welding and cutting mechanism 200 includes a connecting frame 213 fixedly installed between the inner sides of the workbench 1, and two mirror-symmetrical slide rails 211 are fixedly connected to one side of the connecting frame 213. The outer sides of the slide rails 211 are slidably connected to sliding adjustment blocks 212, and the number of the sliding adjustment blocks 212 is two and they are mirror-symmetrical. One side of the corresponding two sliding adjustment blocks 212 is connected to a fixed frame assembly, and an electric cylinder 201 is installed on one side of the fixed frame assembly. A length measuring sensor 205 is fixedly installed on one side of the electric cylinder 201, and the piston rod of the electric cylinder 201 is connected to a strip cutting assembly. A plurality of ultrasonic welding head assemblies are installed on one side of the connecting frame 213.

[0028] It should be noted that the fixing frame assembly includes a mounting plate 2061 and a guide rail clamp 2062; the electric cylinder 201 is fixedly mounted on one side of the mounting plate 2061, and one side of the guide rail clamp 2062 is fixedly mounted on one side of the mounting plate 2061. The guide rail clamp 2062 is slidably connected to the outer side of the slide rail 211, and one side of the mounting plate 2061 is fixedly connected to one side of the corresponding two sliding adjustment blocks 212.

[0029] It should be further explained that the strip cutting assembly includes a strip cutting knife holder 2021, a slide member 2022, a strip cutting knife rod 2023 and a strip cutting knife 2024. The strip cutting knife rod 2023 is fixedly connected to the electric cylinder 201 by a nut, and the inner side of the slide member 2022 is slidingly connected to the outer side of the strip cutting knife rod 2023. One side of the slide member 2022 and one side of the piston rod of the electric cylinder 201 are fixedly connected to one side of the strip cutting knife holder 2021. The inner side of the strip cutting knife 2024 is hinged to the inner side of the strip cutting knife holder 2021 by a pin shaft. The strip cutting knife holder 2021 can move relative to the ultrasonic welding head assembly to adjust the cutting position to adapt to fabrics of different widths.

[0030] It can be understood that the strip cutting assembly and the ultrasonic welding head assembly are integrated into one design. There are several ultrasonic welding head assemblies, which include a fixed plate 207, a transducer 208, a variable amplitude spring 209 and a welding mold 210. One side of the fixed plate 207 is fixedly mounted on one side of the connecting frame 213, the outer side of the transducer 208 is fixedly mounted on the inner side of the fixed plate 207, one side of the variable amplitude spring 209 is fixedly mounted on one side of the fixed plate 207 and is located on the outer side of the transducer 208, and one side of the variable amplitude spring 209 is fixedly connected to the welding mold 210 through a flange in order to control the position of the mold 201 by the variable amplitude spring 209, thereby ensuring the uniformity of the height of the welding surface.

[0031] The transducer 208 is used to convert electrical energy into mechanical energy to generate ultrasonic vibrations; the horn spring 209 is used to amplify the ultrasonic vibrations generated by the transducer 208, and the welding mold 210 is used to transmit the ultrasonic vibrations to the fabric to generate a thermal effect, thereby achieving welding.

[0032] In this embodiment, the surface of the welding roller is distributed with textures, and the textures match the surface pattern of the welding mold 201. The welding roller is used to make the surface of the fabric realize the welding pattern due to the specific surface pattern on the welding mold 201.

[0033] The working principle of the above embodiment is:

[0034] First, the fabric is placed in the opening roller, and the device is adjusted to ensure the flatness of the fabric to meet the requirements of subsequent processing. Then, the fabric passes through the welding mold 210 at a stable set speed, and is efficiently welded under the action of ultrasound to form a strong weld. During the welding process, the specific pattern on the surface of the welding roller contacts the fabric, so that a beautiful and uniform welding pattern is formed on the surface of the fabric. Then, the cloth-pulling roller uses its precise traction effect to smoothly pull the welded fabric to the bottom of the slitting cutting knife 2024, and accurately divide the fabric according to specific needs. The divided fabric is then accurately measured by the length measuring sensor 205 to ensure that the length of each piece of fabric meets the standard. Finally, the fabric is accurately transferred to the storage device by the push of the cloth-pulling roller, completing the entire processing process.

[0035] Compared with the existing technology: this ultrasonic cloth composite welding and cutting device, through the mutual cooperation between the ultrasonic welding and cutting mechanisms 200 on the workbench 1, through the newly added striping structure, not only reduces the tedious steps of secondary cutting according to width requirements after the cloth processing is completed, thereby improving work efficiency, but also significantly reduces the space occupied by the equipment. Under the same working environment, the equipment can be arranged more flexibly, saving production space. In addition, the previous overall welding mold is split into multiple groups, making the power distribution more reasonable, thereby improving the welding effect and ensuring the stability and reliability of the welding quality. When a part of the mold is damaged, only the corresponding module needs to be replaced without disassembling the entire mold, which greatly reduces the maintenance time and cost, and solves the problems of large installation range and high maintenance cost of existing ultrasonic welding and cutting components.

[0036] The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device that controls a computer, etc., and the existing disclosed power connection technology and power supply provision are also common knowledge in this field, so this application will not go into details.
