Problems solved by technology

However, it requires strict control of the heating temperature and heating time. If the heating time is too long or the heating temperature is too high, it will directly melt the packaging material in a large area and affect the appearance; if the heating time is too short or the heating temperature is too low, the seal will not be firm and the seal poor performance

Embodiment 1

[0021] The ultrasonic sealing device includes: an ultrasonic generator, an ultrasonic transducer 10, a vibrating head block 20, a vibrating head block moving part, a stopper 30 and a stopper moving part.

[0022] The ultrasonic generator converts the mains electricity into a high-frequency alternating current signal matched by the ultrasonic transducer.

[0023] The ultrasonic transducer 10 receives the high-frequency electrical signal sent by the ultrasonic generator, and can convert the high-frequency electrical signal into ultrasonic mechanical vibration.

[0024] The main body of the ultrasonic transducer 10 is cylindrical, with symmetrical fixing grooves 11 on both sides of the cylindrical body, and an ultrasonic flange 12 at the lower end. The fixing groove 11 is convenient for fixing the ultrasonic transducer 10 and other components.

[0025] The vibrating head block 20 includes: a connecting flange 21 at the top, a connecting column 22 at the middle and a head body 23...

Embodiment 2

[0032] In this embodiment, the ultrasonic sealing device removes the moving part of the vibrating head block, and the structure and working principle of other components remain unchanged. The vibrating head block 20 is fixedly arranged. The packaging bag B is attached to the vibrating head block 20 and moves. When sealing is required, the block moving part drives the block 30 to move upwards for sealing.

Embodiment 3

[0034] In this embodiment, the moving part of the stopper is removed from the ultrasonic sealing device, and the structures and working principles of other components remain unchanged. Block 30 is fixedly arranged. The packaging bag B moves against the block 30 . When sealing is required, the vibrating head block moving part drives the vibrating head block 20 to move downward for sealing.

Abstract

The invention provides a ultrasonic sealing device. The ultrasonic sealing device comprises a ultrasonic generator, a ultrasonic transducer, a vibration seal block and a stopper, wherein the ultrasonic generator sends a high-frequency electric signal; the ultrasonic transducer converts the high-frequency electric signal to ultrasonic mechanical vibration; the vibration seal block is fixed on the ultrasonic transducer; and the vibration seal block and the stopper perform pressing plastic package. The ultrasonic sealing device has the advantages of simple structure and convenience for operation, adopts mutual friction between surfaces of packing bags to form melting of molecular layers to finish sealing, and effectively improves the sealing quality.

Description

technical field [0001] The invention relates to a sealing device, in particular to a machine for sealing packaging bags using ultrasonic waves. Background technique [0002] Nowadays, packaging products is a necessary process before products are sold. After the product is loaded into the packaging container, in order to keep the product sealed, maintain product quality, and avoid product loss, the packaging container needs to be sealed, and this operation is completed on the sealing device. [0003] Therefore, the quality of the seal that the sealing device completes directly affects the final appearance and quality of the product. Fusion sealing is the most common sealing method, which generally uses heating to partially melt the packaging materials and bond them together. However, it requires strict control of the heating temperature and heating time. If the heating time is too long or the heating temperature is too high, it will directly melt the packaging material in a...
