Description

Brand Description: Ultrasonic plastic welding machine welding plastic products, not only do not add any adhesive, filler or solvent, do not consume large amounts of heat, is a simple, welding speed, welding, high strength, high efficiency production.
Country of Origin: China Asia-Pacific Quality Standard: International Standard Date :2011 -06-22
Category: machinery, electronics, printing, textile machinery, textile and chemical fiber extrusion 8444, drawing, texturing or cutting machine Product Details:
When welding plastics, not only do not add any adhesive, filler or solvent, do not consume large amounts of heat, is a simple, welding speed, welding, high strength, high efficiency production. Therefore, the ultrasonic welding technology becomes more widely available applications.
Ultrasonic plastic welding machine drive system by the air pressure control system, ultrasonic generator, transducer and the tool head and mechanical devices and other components.
1, the pneumatic drive system including: too Hu device, valve, lubricator, commutator, throttle valve, cylinder and so on.
Compressor driven by the first working stroke cylinder to drive ultrasonic transducer vibration system moves up and down, power pressure in the small-power ultrasonic welding pressure needs adjustment according to the welding set.
2, the control system or control system by the time relay circuit time timers. Main functions are: First, the control pressure transmission work, so that time under the control of welding in open gas valve, the cylinder pressure to the welding head down to a certain pressure to suppress the welded object, when a welding after packing time, then the control system for the gas valve to make pick-up reset welding head; two hours to control the ultrasonic generator, the system automates the entire welding process, only when the start button to generate a trigger pulse, to be automatically to complete the whole process in this welding. The order of the whole control system are: the power to start a trigger control signal pressure transmission, cylinder pressure welding head down and hold the trigger ultrasonic welding generator working, launch and maintain a certain ultrasonic welding time to remove the ultrasonic transmitter to maintain a certain pressure of time back pressure pick-up welding welding head end.
3, the ultrasonic generator (1) large power ultrasonic plastic welding machine, the signal generator using phase-locked type frequency automatic tracking circuit, the generator output frequency is basically the transducer resonant frequency.
(2) more than 500W of power in the ultrasonic plastic welding machine with the power generator using a self-excited oscillator, also has a certain frequency tracking capability.

4, ultrasonic plastic welding machine using acoustic system (1) transducer ultrasonic plastic welding machine with the acoustic system consists of three parts: a fixed part of the drive part 2 part 3 work. In the above three components, the drive is the core, generally vertical clamping bolts vibration transducer, which half-wave vertical dipole and a quarter-wavelength vertical dipole, a half-wavelength longitudinal vibration and the half-wave concentrator with connected to form a full wave plastic welding transducer, and a quarter-wavelength vertical dipole and a quarter-wavelength concentrator connected to form a half-wave transducer.
(2) tool head for different objects require different welding tool head, regardless of transmission near-field welding or soldering, only half the wavelength of the tool head to make the maximum amplitude of the weld face. Tool head, with and without amplification amplitude amplitude amplification of the two, plastic welding machine tool head with acoustic systems, the use of material is usually aluminum, the end-plated tungsten carbide, titanium is also useful when the power of the larger materials into the material fatigue strength more than twice as high than the aluminum alloy ultrasonic plastic welding machine commonly used in the automotive industry, electronic industry, medical industry, household appliances, woven apparel, office supplies, packaging industry, the toy industry and so on. Such as plastic body parts, car doors, car car dashboard, headlights mirrors, sun visor, interior parts, filters, reflective materials, reflective spike, bumper, cable, motorcycle plastic filter, heat device, the brake fluid tank, oil cups, water tanks, fuel tank, air hose, exhaust purifiers, tray plate; plastic electronics: prepaid water meter electric meter, communications equipment, cordless phones, mobile phone accessories, mobile phone shell, battery case, charger , valve regulated lead acid battery maintenance, 3-inch floppy disk, U disk, SD card, CF card, USB connector, Bluetooth; toys, stationery: folder, album, folding boxes, PP hollow board, pen, ink cartridges, toner cartridges ,; Medical Daily: watches, kitchenware, oral bottle, drip caps, mobile phone accessories, gold soft brush, household items, hygiene products, childrens products, air mattresses, clothes hangers, knife handle, gardening supplies, kitchenware sanitary , shower, gold soft brush, shower head, anti-counterfeiting bottle, cosmetics bottle, coffee pot, washing machines, air dehumidifier, electric irons, electric kettles, vacuum cleaners, metal speaker grille, side cover and civil.
