[0024] Example

[0025] See also Figure 1-4 The utility model provides a far-infrared automatic heating device for the surface of battery foil, including a control component and a heating component. The heating component includes a bottom connecting plate 1, and an arc-shaped box 2 is fixedly connected to the top of the bottom connecting plate 1. The bottom connecting plate 1 and the arc-shaped box 2 are both made of stainless steel plates. Compared with the flat type, the arc-shaped structure can better fit the surface of the aluminum coil, and the heating area is large and the efficiency is higher. Two mounting plates 3 are symmetrically arranged on the inner side of the arc-shaped box 2, and multiple groups of heating units are arranged between the two mounting plates 3. There are three groups of heating units, and each group of heating units includes three heating tubes 4.

[0026] The heating unit includes a heating tube 4, both ends of which are provided with a ceramic connector 5, and a heating wire 6 is provided inside the heating tube 4, and the heating wire 6 passes through the ceramic connector 5, and the length of the passing portion of the heating wire 6 is 10 mm. The 10 mm passing portion is set because the temperature at both ends of the heating tube 4 is high during operation, and leaving a length of 10 mm as a "cold end" terminal can extend the life of the heating tube 4. The tube body of the heating tube 4 is set as a transparent tube, and a low-cost ceramic layer is coated on the outer surface of the tube body at 180 degrees to ensure that only the direction of the battery foil coil is radiated and heated during operation, so as to achieve the effect of directional heating and maximize the energy consumption utilization rate.

[0027] The mounting plate 3 is provided with a through hole 1, through which the ceramic connector 5 passes and contacts the fixing plate 7. Both ends of the fixing plate 7 are fixed to the mounting plate 3 by screws, and a through hole 2 is provided in the middle of the fixing plate 7 for the heating wire 6 to pass through.

[0028] The arc-shaped box body 2 is provided with an interlayer filled with heat-insulating material. The heat-insulating material prevents the heating tube 4 from conducting heat outward through the stainless steel plate structure. A plurality of cooling fans 8 are arranged above the arc-shaped box body 2. The cooling fans 8 play a cooling role, ventilating and dissipating the heat of the outermost layer conducted from the interlayer, and protecting the overall structure from thermal deformation. A plurality of rows of heat-dissipating holes 9 are arranged at the lower outer side of the arc-shaped box body 2. The heat-dissipating holes 9 play a heat-dissipating role, dissipating the heat on the arc-shaped box body 2.

[0029] A plurality of silent casters 10 are arranged below the bottom connecting plate 1. The silent casters 10 can be arranged to move the heating assembly more conveniently and quickly.

[0030] The control assembly includes a control box, which is provided with a switch button and a knob for adjusting the temperature.

The temperature controller is electrically connected to the solid-state relay, the solid-state relay is electrically connected to the heater, the heater is electrically connected to the temperature controller, and the heater is electrically connected to the circuit breaker. A temperature sensor is provided inside the arc box, and the temperature sensor is electrically connected to the temperature controller. After the user presets the working temperature of the heating device, the working voltage of the heating tube 4 is controlled by the temperature controller, and finally the target heating temperature is achieved to meet the requirements of preheating the surface of the battery foil.

[0031] When in use, the heating device has "automatic" and "manual" modes, and the switch and selection between each "mode" can be completed using the buttons and knobs on the control box. First, in the "automatic" mode, you only need to pre-set the working temperature of the heating device, and the three groups of heating tubes 4 will control one or all of the three groups of heating tubes 4 in turn according to the temperature value of the temperature sensor 4; the "manual" mode requires manual operation and control, and you can manually press the button switch of the group of heating tubes 4 you want to start, and the three groups of heating tubes 4 can be started individually or all at once.

[0032] The heating device is an independently designed heating device and does not need to be fixed. It is equipped with silent and wear-resistant casters at the bottom. It can be easily installed and placed at the unwinder of the battery foil production equipment and can be put into use in the shortest time. The arc-shaped appearance design allows the heating device to be well attached to the surface of the battery foil aluminum coil. The heating area is much larger than the flat structure, and the heating is more accurate and efficient. At the same time, energy consumption is also maximized, which plays a role in energy saving. The use of this device on the battery foil equipment has played a significant role in improving the degreasing effect of the battery foil.

[0033] Therefore, the utility model adopts the above-mentioned structure of the far-infrared automatic heating device for the surface of battery foil. The heating component is independently arranged and does not need to be fixed. The bottom is equipped with silent and wear-resistant silent casters. It can be conveniently and quickly installed and placed on the unwinding machine of the battery foil production equipment and put into use in the shortest time. The arc design of the arc box allows the heating component to be well attached to the surface of the battery foil aluminum coil. The heating area is much larger than that of the flat structure, and the heating is more accurate and efficient. At the same time, energy consumption is also maximized, which plays a role in energy saving and significantly improves the oil removal effect of the battery foil.
