It adopts the principle of electromagnetic induction to convert electrical energy into heat sealing. When the magnetic field passes through the metal, it will generate countless small eddy currents in the metal, causing the heated object to heat up rapidly, thereby achieving the heating effect. Moreover, the heating method is from the inside out, which greatly reduces energy consumption and improves thermal efficiency.

When the agitator rotates, it can deliver the hot melted raw material forward. A filter is located at the outlet of the hot melt chamber; The spinning box has a built-in spinneret. A raw material pipe is connected to the outlet of the hot melt chamber. The raw material pipe extends to the spinning box and is diverted by the spinneret to form a spinning structure. A metering pump, which is installed on the raw material pipeline and records the amount of fluid passing through; The traction device includes an upper traction device and a lower traction device. The upper traction device is used to pull the raw material ejected from the spinneret, and a side blowing box is provided between the upper traction device and the spinneret. The lower traction device can be connected to the upper traction device and further stretch the raw material. A web forming machine is used to lay and shape the raw material stretched by the lower traction device into a web.

Detailed Implementation
[0012] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings: In the description of this utility model, it should be understood that the terms "upper," "lower," "bottom," "top," "front," "rear," "inner," "outer," "left," and "right," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. The specific electromagnetic heating method involved in this article is as follows: AC power is converted into DC voltage through a rectifier, and then the DC voltage is converted into a high-frequency voltage of 20-40KHZ through a control circuit. A magnetic field is generated through high-speed changes. When the magnetic field lines pass through the metal, small eddy currents are generated in the metal, causing it to heat up rapidly. Components such as weighing mixers, hot melt chambers, screws, filters, spinning boxes, metering pumps, traction devices, web forming machines, preheating rollers, rolling mills, oil furnaces, and winding machines can be purchased directly from the market, and will not be described in detail here. The main inventive point of this application is that multi-position electromagnetic heating reduces energy consumption and improves heating efficiency.
[0013] This utility model discloses a nonwoven fabric processing device. In the embodiments of this utility model, it includes... Weighing mixer 1 is used to take a corresponding amount of raw materials and mix them. The hot melt chamber 2 is used to receive and melt the raw materials of the weighing mixer 1; The screw is rotated inside the hot melt chamber 2, and the screw is equipped with a stirring paddle. When the stirring paddle rotates, it can deliver the hot melted raw material forward. Filter 3 is located at the outlet of the hot melt chamber 2; The spinning box 4 has a built-in spinneret. The outlet of the hot melt chamber 2 is connected to a raw material pipe 5. The raw material pipe 5 extends to the spinning box 4 and is diverted by the spinneret to form a spinning structure. Metering pump 6 is installed on raw material pipeline 5 and records the amount of fluid passing through it; The traction device 7 includes an upper traction device and a lower traction device. The upper traction device is used to pull the raw material ejected from the spinneret. A side air box 60 is provided between the upper traction device and the spinneret. The raw material filament ejected from the spinneret is at a high temperature and is relatively soft and difficult to pull out. The side air box 60 can cool it down, thereby making it easier for the upper traction device to pull the raw material filament and deliver it to the lower traction device. The lower traction device can dock with the upper traction device and further stretch the raw material. Web forming machine 8, which is used to lay and shape the raw material stretched by the lower traction device into a web; The preheating roller 9 is located at the outlet end of the web forming machine 8 and can be heated relative to it. A rolling mill 10 is located on one side of the preheating roller 9, and a conveyor belt for feeding the shaped nonwoven fabric to the rolling mill 10 is provided between the preheating roller 9 and the rolling mill 10. The oil furnace 20 includes an oil pump 201, an oil storage tank 202, and an oil pipeline 203, with the oil pipeline 203 extending to the preheating roller 9, the spinning box 4, and the rolling mill 10. The winding machine 30 includes a winding roller that can rotate relative to the winding roller and a drive motor that drives the rotating roller to rotate. Both the hot melt chamber 2 and the oil pipe 203 are equipped with a first heating coil 40 for heating.
[0014] Using the above technical solution, during use, the corresponding amount of raw material is stirred and conveyed by the weighing mixer 1. Preferably, an air pump is used to draw the material into the hot melt chamber 2. At this time, the first heating coil 40 at the hot melt chamber 2 operates, causing the internal temperature of the hot melt chamber 2 to rise and melt the raw material. Simultaneously, the screw rotation further accelerates the melting and extrusion of the raw material, causing it to pass through the filter 3 and enter the spinning box 4 through the raw material pipe 5. At this time, the hot oil in the oil pipe 203 of the oil furnace heats the spinning box 4, and the oil is diverted through the spinneret for spinning. The filaments are then cooled by the side-blowing air box 60, allowing the material ejected from the spinneret to undergo initial cooling. This facilitates manual traction onto the traction device, which further pulls the filaments to the lower traction device. The lower traction device then further thins and evenly distributes the filaments into the web forming machine 8 for web laying and shaping. After shaping, the filaments are hot-pressed by the preheating roller 9 to make them smoother. They are then transported to the rolling mill 10 via a conveyor belt, where they are hot-rolled to form the corresponding pattern. Finally, they are wound up by the rotating take-up roller.
[0015] It also includes an air conditioning unit 50 and a blower 70 for blowing the air from the air conditioning unit 50 to the side-blowing air box 60, so that the cooling effect of the side-blowing air box 60 is better.
[0016] It also includes a smoke extraction fan 80, which is connected to a smoke extraction pipe 90. The smoke extraction pipe 90 extends to the spinning box 4. When spinning, smoke is generated, and the smoke extraction fan 80 can remove the smoke in time.
[0017] A second heating coil (with the same structure as the first heating coil 40, not shown in the attached drawings) is installed on the raw material pipeline 5. When the molten raw material is pushed by the screw, it will enter the raw material pipeline 5 for transportation. During this process, the temperature of the raw material will drop, which will cause local agglomeration. By also installing a heating coil outside the raw material pipeline 5, agglomeration can be prevented.
[0018] Asbestos insulation layer 100 is installed on the raw material pipeline 5, the hot melt chamber 2 and the oil pipeline 203. The first heating coil 40 and the second heating coil are installed on the outside of the corresponding asbestos insulation layer 100. Since the coil heating is from the inside out, the asbestos insulation layer 100 can reduce temperature diffusion, further reduce energy consumption and improve heating efficiency.
[0019] Tin foil insulation layer 200 is provided on the outside of the raw material pipeline 5, the hot melt chamber 2 and the oil pipeline 203 corresponding to the first heating coil 40 and the second heating coil. This can wrap the first heating coil 40 and the second heating coil to prevent them from being directly exposed, and can also further prevent heat dissipation, thus achieving a double insulation effect.
