HF plastic welding machine.Adjustment and principle analysis of embossing machine

　　The proper adjustment of the embossing machine plays a key role in the normal operation, quality improvement and performance maintenance of the embossing machine. But adjust the embossing machine to find the key, so that you can get twice the result with half the effort. Key one, adjust the air pressure. The pressure valve is next to the pressure gauge of the embossing machine. Adjust the pressure according to the thickness of the processed material, or the processing nature (embossing or stitching). When processing thick materials or embossing, the air pressure is higher; On the contrary, when thin materials or sewing edges, the air pressure should be lower. The air pressure is generally adjusted in the range of 2 ~ 5Kg/cm. Key two, embossing machine sonic detection and adjustment. Press the "audio test" switch, if the amplitude display indicator rises sharply and exceeds 100, it means that the frequency is too far away from the resonance point, and the "audio adjustment" twist must be adjusted. Look at the amplitude display of the embosor, press the "audio test" check switch with your left hand (no more than 3 seconds), rotate the "Audio adjustment" twist with your right hand, and adjust the pointer to the lowest point. When adjusting, if the indicator of the embossing machine is not falling, but rising, it will rotate in the opposite direction. The reading of the amplitude meter indicator is within 50, and the reading of the ammeter indicator is below 0.6A. After tuning the sound wave, the butterfly nut should be tightened. The adjustment measures of the embossing machine have a profound impact on improving the quality of embossing, so the adjustment of the embossing machine should be paid attention to.

　　Analysis of the working principle of the embossing roller In general, there are two types of embossing roller process, one is a plate, the other is a roller, different processes have different working principles. For the electric engraving roller is the printing roller printing depth of about 38 microns to 42 microns of etching roller or electric engraving roller is changed to the printing screen depth of about 24 microns to 28 microns of laser plate making roller, printing roller also needs to use corrosion resistant materials to manufacture. So what we have to do is different working principles have different ways of operating, let's take a look at it in detail. The steel plate (embossed plate) or roller (embossed roller) engraved with different patterns is used to press out patterns or simulate some animal skin grain patterns on the leather surface to cover up the original grain defects of the leather, improve the appearance and beautify, and improve the use value. The type of embossing process: there are plate and roll. The plate embossing form is the same as the plate ironing machine, including a heated upper plate engraved with a pattern and a lower plate covered with felt. Through the ironing effect of the contact between the upper and lower plates, the leather surface placed between them is pressed out a pattern. The roller embossing equipment consists of a heating roller and a lower embossing roller engraved with a pattern, and the leather is pressed out of the pattern when passing between the two rotating rollers.
