Description

Technical Field

[0001] This utility model relates to the field of garment processing technology, and in particular to a safety ultrasonic placket machine with a movable ultrasonic steel mold. Background Technology

[0002] An ultrasonic placket machine is a widely used piece of equipment in the garment manufacturing industry, primarily used for welding and cutting fabric simultaneously. Its working principle involves using the energy of ultrasonic vibrations to heat the fabric, achieving precise cutting and edge sealing. This equipment plays a crucial role in garment production, especially suitable for welding and cutting delicate areas such as plackets.

[0003] In existing technologies, ultrasonic placket machines typically use a fixed ultrasonic welding mold to provide stable support for the cutting head. However, with the increase in the number of welding and cutting cycles, the ultrasonic welding mold inevitably suffers wear due to the repeated action of the cutting head, especially resulting in dents or pits. This wear can cause the fabric welded edges to become brittle and connected, thus affecting the welding and cutting quality and even leading to fabric scrap. To solve this problem, the industry typically addresses it through the following methods:

[0004] 1. Frequent replacement of ultrasonic welding molds: When ultrasonic welding molds show wear, operators often choose to replace the entire mold. However, because ultrasonic welding molds are often large and have high manufacturing costs, frequent replacements not only result in a huge waste of resources but also significantly increase equipment maintenance costs. Furthermore, overly frequent replacements can cause production interruptions and affect production efficiency.

[0005] 2. Continuing to use worn ultrasonic molds: Some operators choose to continue using worn ultrasonic molds to avoid the high cost of replacement. However, this often leads to decreased stability of the welding and cutting head, severely affecting welding and cutting accuracy, resulting in decreased product quality and an increased proportion of defective products. This can cause serious economic losses in mass production.

[0006] 3. Attempt localized repair of ultrasonic steel molds: The industry also offers repair services for locally worn ultrasonic steel molds, such as grinding surfaces, filling dents, or using temporary shims to restore support. However, this method involves a more complex structure and relatively lower stability.

[0007] Therefore, how to extend the service life of ultrasonic welding steel molds, avoid frequent replacements, and ensure welding and cutting accuracy has become the technical problem to be solved by this utility model. Utility Model Content

[0049] Example 1:

[0050] In garment manufacturing, ultrasonic placket machines are used for welding and edge treatment of the placket area. They use ultrasonic vibration to heat and cut and fuse the fabric edges, achieving precise cutting and edge welding of fabric 14. However, after prolonged use, the ultrasonic welding mold of existing ultrasonic placket machines inevitably develops pits and wear due to the repeated action of the cutting head. This not only leads to decreased stability of the ultrasonic mold and reduced welding accuracy but also increases the frequency of equipment maintenance. Especially in large-scale production, frequent replacement of the ultrasonic mold significantly increases production costs, wastes resources, and affects production efficiency.

[0051] This utility model discloses a safety ultrasonic placket machine with a movable ultrasonic steel mold, specifically addressing the problems in the aforementioned scenarios with an optimized design. Its specific application scenarios are as follows:

[0052] When producing garments from a batch of fabric, the ultrasonic steel mold bears a greater load (emitting 15,000-20,000 vibrations per second) because the fabric cutting blades act on the ultrasonic steel mold's working screen. Therefore, during continuous high-friction welding and cutting tasks, deep pits are easily formed on the ultrasonic steel mold. Traditionally, operators must replace the entire ultrasonic steel mold when it shows significant wear. Since the ultrasonic steel mold is large and expensive, this not only wastes resources but also causes equipment downtime, affecting the overall production line operation and, in severe cases, even causing delivery delays.

[0053] This invention effectively solves this problem through the design of a movable ultrasonic welding mold 5. In its structure, the top of the ultrasonic welding mold 5 extends into the ultrasonic welding mold clearance hole 4 and is connected to the positioning plate 2 via a pull-up limiting mechanism. This design allows operators to manually adjust the position of the ultrasonic welding mold to a new, wear-free area by loosening the bolt locking mechanism when pits or localized wear are found, without immediately replacing the entire ultrasonic welding mold. After adjustment, the ultrasonic welding mold is then fixed in place by the bolt locking mechanism, ensuring its stability and support in the new working position.

[0054] In practical use, when pits appear on the ultrasonic steel mold 5, affecting the welding quality, the operator only needs to loosen the fixing bolts briefly, move the ultrasonic steel mold along the ultrasonic steel mold avoidance hole 4 to avoid the worn area, and then re-tighten it. This process is simple and quick, avoiding the time waste caused by having to stop the machine to replace the entire ultrasonic steel mold in the traditional method. Since only the position of the ultrasonic steel module needs to be adjusted, rather than the entire module being replaced, the production line can quickly resume operation, greatly reducing downtime and thus improving production efficiency.

[0055] Furthermore, thanks to the limiting and bolt locking mechanism design adopted in this invention, even after multiple adjustments, the ultrasonic welding mold can still provide stable support in its new working position, avoiding welding and cutting errors caused by blade vibration during welding and cutting. Therefore, this design ensures that welding and cutting accuracy and production efficiency remain at a high level even after long-term use of the equipment.

[0056] For example, in a garment factory mass-producing seamless polo shirts of a certain brand, due to the complex welding and cutting process and the thick fabric, multiple pits appeared on the surface of the ultrasonic welding mold after two consecutive days of operation. Traditionally, these pits could cause the welding and cutting head to shift, resulting in uneven weld lines and affecting the overall appearance and quality of the down jacket placket. Traditionally, the factory would need to shut down and replace the entire ultrasonic welding mold, wasting considerable time and money. However, with the ultrasonic placket machine of this invention, operators only need to briefly pause the machine during operation, loosen the bolts to adjust the ultrasonic welding mold to an unworn area, and production can resume. This ensures welding and cutting accuracy while avoiding economic losses caused by production stoppages.

[0057] Furthermore, the transparent annular cover design of this invention provides additional safety protection for the welding and cutting head. During the adjustment of the ultrasonic steel module, the operator's hands will not come into contact with the exposed cutting head, effectively preventing accidental injuries and improving the overall operational safety of the equipment. At the same time, the cloth limiting strip 13 set on the welding and cutting table 3 ensures the precise positioning of the cloth during the welding and cutting process, preventing the cloth from shifting during welding and cutting and affecting the quality of the final product.

[0058] In summary, this embodiment demonstrates through practical application that the movable ultrasonic welding mold design significantly extends the service life of the ultrasonic welding mold, reduces resource waste and replacement costs, and ensures that welding and cutting accuracy remains at a high level even after prolonged use. This solves the problems of resource waste and production interruptions caused by frequent replacement of ultrasonic welding molds in traditional equipment. At the same time, the safety and ease of operation of the equipment are also improved.

Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
