PVC mesh welding machine.Precautions for the operation of leather embossing machine

　　Leather embossing machine can also be called high frequency embossing machine, high frequency embossing machine, high frequency branding machine, mainly the use of high voltage rectification self-excited high frequency electron tube oscillation moment, resulting in electromagnetic wave current electric field, which is used and processed PVC, TPU, EVA, PET and other materials of plastic, leather materials. Because the material can generate polar friction on the internal molecules of the material in the electromagnetic field to generate heat, coupled with a certain pressure and finally achieve the effect of branding and fusion sealing on materials such as leather plastic, these are the approximate working process of the leather embossing machine.

　　The main working principle of the leather embodying machine is that the high frequency current flows to the heating coil made of the embodying machine, which is commonly known as the copper tube, resulting in a strong magnetic beam of instantaneous transformation of polarization in the coil, and then the magnetic beam is transported to the leather surface through the mold, in the opposite direction of the leather and heating current, there will be a corresponding strong eddy current. Due to the resistance in the body of the leather material, this will cause the leather surface to produce a lot of Joule heat, and eventually the temperature of the leather itself rises rapidly to achieve the purpose of leaving a brand on the surface of the leather plastic rubber.

　　Before the operation of the embossing machine, check the hydraulic oil quantity, the oil quantity of the embossing machine must meet the standard to work normally, the embossing machine must be filtered before oil injection, in order to inject the embossing machine, it is also necessary to check the lubrication between the column shaft and the guide frame, after the embossing machine is connected to the power supply, then put the handle in a vertical position, close the oil return port, Then press the motor start button of the embossing machine, and the embossing machine will enter the state of stopping and maintaining pressure, and reach the vulcanization time to make the plunger drop and open the mold.

　　Pay attention to the temperature control of the hot plate of the embossing machine, reasonable rotation button, the plate begins to heat, when the temperature of the embossing machine plate reaches a specific temperature, it will automatically stop heating, if the temperature of the embossing machine is lower than the set value, the plate will automatically heat, keep the temperature always at the set value, when the embossing machine vulcanization, press the motor start button AC contactor to obtain electricity, The oil pump starts to work, and the AC contactor will be disconnected if the press of the embossing machine reaches the set value.
