Description

Technical Field

[0001] This utility model belongs to the technical field of pneumatic seam opening machine, and in particular relates to a pneumatic seam opening machine with staggered welding heads. Background Technology

[0002] Ultrasonic sewing machines are used for bonding and embossing of various chemical fiber fabrics, non-woven fabrics, spray-bonded cotton, artificial leather and other fabrics. The working principle is that the fabric passes between the working roller (the working roller is a smooth roller or an embossing roller with a pattern on the surface) and the ultrasonic device. The ultrasonic device vibrates to generate energy, so that the pattern on the embossing roller is printed on the fabric, or the tail of one fabric is fused with the head of another fabric to connect the two sides.

[0003] In traditional machines, changing the embossing roller requires manually cranking a screw to raise or lower the roller (while the roller itself remains stationary). After changing the roller, if the embossing effect at a certain ultrasonic welding head assembly is poor, the height of the ultrasonic welding head assembly must first be lowered, and then the welding head must be leveled. This process takes a considerable amount of time to adjust a single welding head, and the traditional spring-pressurized method results in significant pressure fluctuations, which can easily lead to poor welding results. The improved pressurization method uses a cylinder, resulting in stable pressure.

[0004] To address these issues, we provide a pneumatic seam opening machine with staggered welding heads. Utility Model Content

[0005] The purpose of this utility model is to provide a pneumatic sewing machine with staggered welding heads. By cooperating with the inclined pressure welding head base and the right angle welding head base, it solves the problem in the prior art that there is an unavoidable gap between the two welding heads of the pneumatic sewing machine, and the gap cannot be used to laminate the fabric.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0024] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Please see Figure 1-5 This utility model is a pneumatic seam opening machine with staggered welding heads, including a main frame 1. A large plate 2 is fixedly connected to the top of the front of the main frame 1. An inclined pressure welding head base 3 is fixedly connected to the front of the large plate 2. A right angle welding head base 4 is fixedly connected to the front of the large plate 2 and one side of the inclined pressure welding head base 3. A lifting welding head assembly 5 is provided at the bottom of the right angle welding head base 4. The lifting welding head assembly 5 includes a transition plate 501, which is located below the right angle welding head base 4. A structural support rod 502 is fixedly connected to the bottom of the transition plate 501. A mounting base 503 is fixedly connected to the bottom of the structural support rod 502. An ultrasonic welding head assembly 504 is provided at the bottom of the mounting base 503. A cylinder connecting rod 505 is fixedly connected to the top of the transition plate 501. The right angle welding head base 4 includes a right angle base 401, one side of which is fixedly connected to the surface of the large plate 2. A first cylinder 402 is provided at the top of the right angle base 401.

[0026] The first cylinder 402 drives the cylinder connecting rod 505, pushing the adapter plate 501 to move vertically. The adapter plate 501 drives the mounting base 503 and the ultrasonic welding head assembly 504 to rise and fall synchronously through the structural support rod 502. The ultrasonic welding head assembly 504 descends and presses the fabric onto the surface of the embossing roller 12, and embossing is completed by ultrasonic vibration. The first cylinder 402 drives the welding head assembly to rise and fall with one key. When replacing the embossing roller 12, there is no need to manually adjust the height of the welding head. The first cylinder 402 applies pressure instead of the traditional spring, resulting in small pressure fluctuations and avoiding poor welding.

[0027] A feed pipe 6 is provided at the bottom of the inner cavity of the main frame 1. A feed roller 7 is provided in the inner cavity of the main frame 1 above the feed pipe 6. A second cylinder 8 is provided at both ends of the feed roller 7. An embossing roller slide 9 is fixedly connected to one side of the top of the main frame 1. A split bearing seat 10 is movably connected to the top of the embossing roller slide 9. A bearing component 11 is provided on one side of the split bearing seat 10. An embossing roller 12 is provided in the inner cavity of the bearing component 11. A transducer cover 13 is fixedly connected to the bottom of the right-angle base 401. A heat dissipation device is provided on the front of the transducer cover 13. The fan 14 and the mounting base 503 are fixedly connected to a guide shaft 506 on one side of the top by screws. The guide shaft 506 is connected to the limiting hole on the surface of the adapter plate 501. The right-angle base 401 is provided with a shaft elastic retaining ring 403 on the top. The inner cavity of the shaft elastic retaining ring 403 is provided with a linear bearing 404. The electrical cabinet 15 is fixedly connected to one side of the top of the main frame 1. The air circuit control board 16 is fixedly connected to the top of the main frame 1. The four corners of the bottom of the main frame 1 are fixedly connected with support pads. The bottom of the support pads is provided with anti-slip particles.

[0028] The fabric is passed between the feed roller 7 and the feed tube 6, through the surface of the embossing roller 12, and pressed tightly against the embossing roller 12. To disassemble the embossing roller 12, simply lift all the lifting welding head assemblies 5 with one key, then remove the split bearing seat 10, and roll the embossing roller 12 down from the embossing roller slide 9. The transducer cover 13 can prevent the ultrasonic transducer on the ultrasonic welding head assembly 504 from being accidentally damaged. The cooling fan 14 can keep the ultrasonic transducer on the ultrasonic welding head assembly 504 at a suitable working temperature for a long time, with strong regional adaptability. The guide optical shaft 506 is connected to the mounting base 503 by screws and cooperates with the limiting hole on the adapter plate 501 to prevent the ultrasonic welding head assembly 504 from shaking during lifting. The limiting structure composed of the elastic retaining ring and the linear bearing 404 can limit the guide optical shaft 506, improving the movement stability of the guide optical shaft 506 and the ultrasonic welding head assembly 504 at its bottom. The electrical cabinet 15 is used for collecting The electrical control system of the installed equipment, such as the ultrasonic generator and PLC controller, realizes precise power supply and programmed control of the ultrasonic welding head assembly 504, cooling fan 14, first cylinder 402 and second cylinder 8. The PLC controller controlling the overall device to perform embossing is existing technology, such as the ultrasonic sewing machine disclosed in CN103417331B. The air circuit control board 16 integrates pneumatic circuit components such as solenoid valves and pressure regulating valves to uniformly manage the compressed air supply and direction switching of multiple cylinders, such as the first cylinder 402, lifting welding head assembly 5, feeding roller 7 and second cylinder 8. The air circuit control board 16 adopts the OptiFlexPro series. At the same time, the debugging of the unified management of multiple cylinders is also existing technology, such as the multi-cylinder synchronization technology disclosed in patent CN105483877B. The equipment debugging is not the customer to be protected in this application, so it will not be elaborated on further.

[0029] The high friction at the bottom of the support pad improves the overall stability of the device by supporting the bottom of the main frame 1.

[0030] The working principle of this utility model is as follows: When the power is turned on, the ultrasonic transducer on the ultrasonic welding head assembly 504 starts working, and the cooling fan 14 starts synchronously to stabilize the temperature of the ultrasonic transducer on the ultrasonic welding head assembly 504 within the set range. The operator sets the embossing parameters through the control panel on the electrical cabinet 15. The initial position of the first cylinder 402 is the working surface of the ultrasonic welding head assembly 504 in the raised state. The chemical fiber fabric or non-woven fabric passes between the embossing roller 12 and the ultrasonic welding head assembly 504. The first cylinder 402 drives the lifting welding head assembly 5 to descend, so that the working surface of the ultrasonic welding head assembly 504 contacts the fabric with constant pressure. The ultrasonic welding head assembly 504 on the right-angle welding head base 4 and the inclined pressure welding head base 3 overlap in the direction of fabric projection. The process involves stacking elements to eliminate gaps between rows, achieving continuous composite embossing. If the embossing depth is insufficient or excessive, the operator can directly turn the adjusting handle on the first cylinder 402. The adjusting handle changes the height of the mounting base 503 via the fine-tuning cylinder connecting rod 505, allowing the working surface of the ultrasonic welding head assembly 504 to rise and fall precisely without stopping the machine or disassembling parts. Triggering the "one-key lifting" button causes all first cylinders 402 to simultaneously lift the ultrasonic welding head assembly 504, completely detaching it from the embossing roller 12. The split bearing seat 10 is then disassembled, and the embossing roller 12 rolls out of the equipment along the embossing roller slide 9. After installing a new embossing roller 12, only the height of the ultrasonic welding head assembly 504 needs to be uniformly fine-tuned using the first cylinder 402, and the split bearing seat 10 needs to be reset for the equipment to restart.
