Efficient mini sound insulation bin

Abstract

Disclosed is an efficient mini sound insulation bin. The sound insulation bin with five faces integrated is divided into three relatively independent units, a front face shield and two side face shields form a U-shaped floating shield serving as a first unit, a base serving as a second unit is fixed on a worktop, and a top cover plate serving as a third unit is fixed at the lower end of a transducer protective seat. A through hole with diameter larger than diameter of a corresponding position of an amplitude transformer is arranged at the position, passing the axis of a sound head, on the top cover plate so as to avoid the amplitude transformer during mounting. Drooping support plates are arranged at a left end and a right end of the top cover plate to form a pi-shaped structure, a horizontal rotating shaft is arranged at the lower end of each support plate, connecting rods hinged on the rotating shafts extend forwards and backwards respectively, the front end of each connecting rod is hinged with the floating shield in a floating manner, and the rear end of each connecting rod is hinged with the base in a floating manner. When the sound head ascends and descends, the intermediate rotating shaft between the connecting rods ascends and descends synchronously and equidistantly along with the sound head, and the rear end of each connecting rod is limited by the base to be incapable of ascending and descending, so that the connecting rods are forced to rotate while ascending and descending, the floating shield is driven by the front ends of the connecting rods to ascend and descend synchronously, ascending and descending distances of the floating shield are larger than those of the sound head, and enough operating space can be opened.

Description

Technical field [0001] The invention relates to a noise reduction and sound insulation cabin for equipment, in particular to a miniaturized and efficient mini sound insulation cabin for ultrasonic welding equipment. Background technique [0002] The instantaneous noise when the ultrasonic welding equipment is working can be as high as about 110 decibels, and the sound insulation cabin can reduce the noise by about 30 decibels, which is an indispensable labor protection equipment for ultrasonic welding equipment. At present, the known noise-reducing and sound-insulating cabins of ultrasonic welding equipment are composed of four front, rear, left, right, left and right masks and a top cover to form a five-sided integral frame cover, which covers the entire ultrasonic welding equipment, wherein the front cover is provided with an automatic switch. Automatic door, when working, the operator sends the workpiece to be welded into the soundproof warehouse through the opened automa...

Problems solved by technology

[0005] In order to overcome the disadvantages of the existing noise-reducing and sound-insulating cabins, such as large volume, high cost, and low production efficiency, the present invention provides a high-efficiency mini-sound-insulating cabin, which no longer covers the entire ultrasonic welding equipment, but only covers the noise source (that is, the sound head and tooling), and at the same time, it can conveniently open enough space without changing the main structure and operation mode of the existing equipment, so that the operator can take and place the workpiece; the soundproof warehouse not only reduces the volume several times and saves A set of drive control system can be directly installed on the small workbench of ordinary desktop standard ultrasonic welding equipment without adding a large-sized cabinet base to the equipment, thereby further reducing the cost of manufacturing, packaging and transportation of the entire equipment; in addition, the present invention The high-efficiency mini-soundproof cabin can also improve the operation interface, improve work efficiency, and facilitate parameter setting and equipment maintenance and repair
