Working Principle and Characteristic of RF Dryer

图片
  RF dryer is a kind of high efficiency leather drying equipment.   Working principle of RF Dryer In the high-frequency electric field, the dielectric water in the wet leather will be affected by the electric field, causing molecular disturbance and friction and heat between molecules, so that the moisture in the leather will get enough heat and vaporize, and then the steam will be taken away by the air to achieve the purpose of leather drying.   Characteristics of high frequency dryer (1) The RF dryer working speed is fast because the electrical energy into heat, high frequency electric field and leather do not need any intermediary, so in the moment that leather is electrified, heat will produce, to achieve the purpose of rapid drying.   (2) Uniform drying, good leather quality if the leather dry to the specific moisture content, will encounter a lot of problems, one of them is the moisture uniformity problem. In the past, most tanneries have dried the leather to a leathery state and

The Welding Method of Conveyor Belt Welding Machine

图片
  Plastic welding process of conveyor belt welding machine is achieved in there ways, softening by external heat source, softening by mechanical motion and softening by electromagnetic action.   Conveyor belt welder  used in hot plate welding can be said to be the most simple plastic welding technology. It is especially suitable for welding large plastic materials which need large area of welding surface. The general conveyor belt welding machine acts on the waterproof material. The heat produced softens the product. The period is longer. The molten resin will stick to the waterproofing board and it will not be easy to clean. Impurities that affect bonding strength will be formed for a long time. Pressure and time should be strictly controlled to ensure proper melting amount. With different kinds of resin or metal and resin joint, there will be insufficient strength. But the conveyor belt welding machine produced by our company adopts the way that welding device is simple and welding s

What is the Difference Between Automatic High Frequency Welding Machine and Hot Press Machining?

  What is the difference between automatic high frequency welding machine and heat-sealing machine heat sealing machine? We briefly introduce the different principles between high frequency voltage processing and hot sealing machine, the different ranges of processed products, as well as the advantages and disadvantages of high frequency processing and hot sealing machine processing, so as to help customers understand the specific differences between high frequency processing and hot sealing machine processing.   Different principle: High frequency processing principle: as we have said earlier, "automatic high frequency welding machine welding principle" the high frequency magnetic field energy emitted by high frequency tube oscillation, and the conduction effect in the processing of plastic parts, high frequency energy permeability material molecules inside, quickly make plastic molecule polarization of plastic material, material molecules arranged in the same direction with

Non-Woven Heat Welding Machine

  The theory of high frequency welding equipment : Under the effect of the high frequency electric field, the positive and negative charges of the substance to be heated displace to form electric pole polarons. The polarons polarize repeatedly to cause the molecules to produce the intense friction to give heat out. The electric field energy absorbed by the substance changes into heat energy to realize the purpose of heating.   Machine classification of RF  welder for sale The high frequency welding machine(HF machine) can be divided as follows according to the industry: HF plastic welding machine, RF heat sealing equipment, medical bag making machine and car interior heat sealing welding equipment, inflatable thermal welding equipment, radio frequency plastic welding machine, membrane structure canvas welding equipment, belt welding machine like industrial belt skirt side baffles welding machine, non-woven heat sealing welding equipment, packaging blister heat sealing equipment, flexib

HF Blister Packaging Welders

图片
  The HF blister welding machine  is an inexpensive option for creating packages that are durable, transparent, and tamper proof. We make a variety of shapes and can custom design a blister pack that will showcase your product in the best possible manner. Although we strive to provide our customers a very competitive price, we will not sacrifice quality to do so. All products are tested for clarity, wall thickness, and dimensional compliance before leaving our plant.   A clear plastic blister pack can be used in conjunction with a cardboard blister card to keep the product in full view for the customer to examine. The blister packaging is attached to the blister card through a heat-sealing process of high frequency blister sealing machine that allows the product to be displayed in a wide variety of methods. While this heat sealing process can be done with highly automated equipment, the use of blister packs is somewhat limited to light weight items. For heavier contents, a plastic clam

Precautions for the Use of Leather Embossing Machine

  Liaoning Unify High Frequency Equipment Co., Ltd. has the most professional technicians and the best high frequency embossing machine . Below are the top 10 things that Unify will tell you when using:   1. This unit must be equipped with a good ground terminal (connected to the correct ground wire). 2. The machine is extremely sensitive to moisture and dust and needs to be placed in a suitable working space. 3. The vacuum tube of the machine will generate high heat, so it should not be placed next to the machine that will generate high heat, nor should it be installed in the place where the solar energy is directly irradiated. For the above reasons, the heat dissipation function of the vacuum tube will be affected. 4. If the machine is shut down for more than one hour, and then turn on the machine, wait 10-15 minutes for the vacuum tube to warm up and protect the service life of the vacuum tube. 5. The upper and lower extremes of the machine (upper and lower molds) must not be direct
