Description

Technical Field

[0001] This utility model relates to the field of pocket spring processing equipment, and in particular to an ultrasonic cutting tool for packaging pocket springs for mattresses. Background Technology

[0002] Pocket springs are an essential component in assembling spring mattresses. A pocket spring consists of a fabric pocket and a spring housed within it. Depending on their support performance, springs are further categorized into cylindrical coil springs and variable-diameter coil springs. To better confine these springs within the fabric pocket, ensuring they move only vertically during mattress operation and preventing lateral tilting or deformation, the fabric pocket is typically welded tightly to the outer diameter of the spring using an ultrasonic welding tool, starting from both vertical sides of the spring. This ensures the pocket spring moves only vertically during operation. To achieve this, a straight ultrasonic welding tool is used when using cylindrical coil springs, and a curved tool is used when using variable-diameter coil springs. Currently, both straight and curved ultrasonic welding tools are machined as a single piece. Furthermore, based on the varying height and length of pocket springs, ultrasonic cutters are correspondingly categorized into long cutters, medium cutters, and short cutters. Similarly, based on the diameter variation of variable-diameter helical springs, curved cutters are categorized into large curved cutters, medium curved cutters, and small curved cutters. This means that pocket spring manufacturers must maintain a full range of ultrasonic cutters of various specifications to meet daily production needs. This significantly increases the capital tied up in pocket springs and requires substantial workshop space to store the various sizes of ultrasonic cutters, as well as the time and resources needed to maintain them, resulting in high operating costs and hindering market competitiveness. Therefore, given the negative impact of the existing ultrasonic cutters' unscientific and unreasonable structural design on pocket spring manufacturers, the applicant believes it is essential to redesign the existing ultrasonic cutters to meet the application needs of pocket spring manufacturers.

[0016] like Figure 1 , Figure 2 and Figure 3 As shown, the ultrasonic welding tool device for processing bag springs according to this utility model includes a tool holder assembly 1. One side of the tool holder assembly 1 has a fixing part 11 for mounting on a device, and the other side has a blade mounting groove 12. Several blade pieces 2 are included, each blade piece 2 consisting of a mounting part 21, a transition part 22, and a cutting edge 23. The transition part 22 has a straight or offset structure. The mounting parts 21 of each blade piece 2 are arranged, embedded, and fixed in the blade mounting groove 12, so that each blade piece 2 and the tool holder assembly 1 are assembled into an assembled ultrasonic tool 4. When the transition part 22 has a straight structure, the cutting edge of the ultrasonic tool 4 is straight; when the transition part 22 has an offset structure, the cutting edge of the ultrasonic tool 4 is curved. Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, by designing the blade part 2 into various shapes and specifications, users can flexibly assemble straight blades and curved blades of different lengths and specifications according to the production needs of pocket springs, thus meeting the needs of production applications.

[0017] To ensure that the tool holder assembly 1 has the characteristics of simple structure, easy implementation, and high reliability, such as Figure 1As shown, the blade holder assembly 1 is strip-shaped, consisting of a fixing part 11, a blade mounting part 13, and a bent transition part 14 disposed between the fixing part 11 and the blade mounting part 13. The blade mounting part 13 has a blade mounting groove 12 along its length. The fixing part 11 facilitates fixing the blade holder assembly 1 to the blade holder mounting base of an existing ultrasonic welding equipment. The blade mounting part 13 facilitates the opening of the blade mounting groove 12, thereby facilitating the installation of each blade component 2. In practical applications, two ultrasonic cutters 4 can be installed at the upper and lower ends of the ultrasonic welding equipment's blade holder mounting base. The bent transition part 14 shortens the distance between the blade components 2 of the two ultrasonic cutters 4. This allows for a narrower gap between the welded seals of adjacent pocket springs during welding, preventing excessive width and ensuring a tighter connection between the pocket springs. This results in a mattress with excellent support and comfort, making the mattress more reliable and comfortable to use. Specifically, as... Figure 2 As shown, an installation space 15 for mounting and limiting the heightening shim is also formed between the fixing part 11 and the bending transition part 14. In application, the heightening shim is placed between the fixing part 11 and the tool holder mounting seat of the ultrasonic welding equipment, which can widen the distance between the blades 2 of the two ultrasonic tools 4, thereby adjusting the distance between the welding seals of two adjacent pocket springs. This can adapt to the production and manufacturing of pocket springs of various specifications and functions, thus solving the defects of the current one-piece double-row pocket spring ultrasonic welding tools.

[0018] In order to securely lock each blade component 2 and to facilitate the disassembly and replacement of blade components 2 of various shapes and specifications, such as Figure 2 As shown, the side of the blade mounting part 13 is also provided with several screw holes 131 that pass through the blade mounting groove 12. Each blade component 2 is locked by screwing screws 3 into the screw holes 131, and the blade component 2 is clamped by the screws 3, thus achieving the purpose of fixed installation. It is not necessary to make corresponding screw holes for each blade component 2, so as to save the trouble of matching holes and improve the installation convenience of each blade component 2.

[0019] To ensure the accuracy and stability of the tool holder assembly 1 when assembled onto the tool holder mounting base of the ultrasonic welding equipment, such as Figure 1 As shown, the fixing part 11 is also provided with a plurality of elongated elliptical fixing holes 110. The design of the elongated elliptical fixing holes 110 provides a larger adjustment space, allowing for parallel fine-tuning during installation and ensuring the accuracy and stability of assembly onto the tool holder mounting base of the ultrasonic welding equipment.

[0020] To ensure that the cutting edge 23 has the characteristics of simple structure, easy implementation, and high reliability, such as Figure 3As shown, the blade portion 23 is composed of teeth 231 machined on the outer side of the transition portion 22. This allows for ultrasonic spot welding of the pocket spring fabric during ultrasonic welding, thereby forming spot-like sealing lines on the pocket spring fabric.
