　　How is the ultrasonic heat sealing embossing machine heated

　　High frequency embossing machines and leather embossing machines can be divided into heat sealing embossing machines according to the heating method. There are three main categories of ultrasonic embossing machines, which can be further divided into many subcategories based on the use of field data. Such as high-frequency decoration embossing machine, high-frequency leather embossing machine, concave convex embossing machine, knitted fabric embossing machine, ultrasonic lace machine. According to the different products produced by the decoration leather embossing machine, there are garment embossing machine, car seat cushion embossing machine, door pad embossing machine, cutting piece embossing machine, shoe leather embossing machine, luggage embossing machine, leather clothing label embossing machine, trademark embossing machine, ultrasonic mask machine, ultrasonic shoe pad machine.

　　Today, we will mainly explore the innovation of heating methods for heat sealing embossing machines. The embossing principle of heat sealing clothing leather embossing machines is to use an electric (ultrasonic) heating pattern to transfer the heat from the heating plate to the fusion surface of the concave convex plastic heating element. Melt its surface, then quickly withdraw the heating plate. After heating the concave and convex heating elements, the melted surface fuses, solidifies, and merges into one. The leather embossing machine adopts a pull-out plate structure, and the whole machine is in the form of a frame. It consists of three large plates: an upper template, a lower template, and a hot template, and is equipped with a hot mold and a concave convex plastic cold mold. The action mode is oil/pneumatic control. Set up two temperature controllers to separately control the temperature of the concave convex mold. During welding, it can be set within the range of 0400 ℃ according to the actual needs during welding. Ultrasonic embossing machine manufacturers can set heating power and mold size according to different sizes of plastic parts to achieve welding of various plastic workpieces.

　　The concave convex hot template of the heat sealing machine embossing machine is heated by several heating tubes, which is a simple processing method. However, its disadvantages are self-evident, such as low heating temperature (can only be increased to 400 degrees), high power consumption (at least 10 heating tubes are needed for one machine with 800W heating tube), slow heating speed, uneven heating, and difficult maintenance (the root wire of the heating tube is prone to breakage, and if it breaks, it can only replace the heating plate because of thermal expansion and contraction. The heating tube cannot be extracted). By solving this erroneous assumption, it is possible to improve this aspect. The direction of improvement is not to change the assumption and processing of the heating template, because the core of the heating template is the heating source! Since there are so many disadvantages of the difficult heating tube, what heating method can possibly replace it? The answer is - heat-resistant glass, which can be heated and then conducted onto a thermal template.

　　So what are the advantages of heat-resistant glass? Let me elaborate on them above. Heat resistant glass (refers to a special type of glass that contains strong heat-resistant components such as boric acid and silicic acid, and can withstand the temperature difference changes caused by cold and hot fusion. Its coefficient of thermal expansion (the ratio of glass body expansion due to temperature advancement) is small, and it is not easily broken under rapid temperature changes. It has a series of exquisite functions such as low expansion, thermal shock resistance, high temperature resistance, corrosion resistance, and strength. Therefore, the selling price of heat-resistant glass is higher than that of ordinary glass and tempered glass. The heat-resistant glass material has a high handling safety factor and will not cause self explosion similar to tempered glass; The heat shrinkage coefficient is small, and it has a large range of resistance to rapid temperature changes (≥ 120 ℃) and can withstand high temperatures up to 1200 ℃. Heat resistant glass is commonly used in containers, milk bottles, beakers for implementation, industrial boiler sight glasses, mechanical equipment window glass, etc. Regarding my leather embossing machine for dressing up. What can be utilized are low expansion, thermal shock resistance, and ultra-low temperature resistance.
