Description

TECHNICAL FIELD

[0001] The present application relates to the field of chemical conversion foil production, and more particularly, to a sheet burning furnace device. BACKGROUND

[0002] The sheet burning furnace on the chemical conversion production line is mainly used for high-temperature rapid dehydration of the foil. During the operation of the high-pressure chemical conversion machine, as the vehicle speed and the chemical conversion current continue to increase, the connection strength of the foil joint significantly decreases after the first few chemical conversion processes. This phenomenon causes the joint to easily break and be pulled apart when passing through the existing sheet burning furnace of the machine.

[0003] Currently, the remedial measures taken to address this problem are as follows: before the joint enters the furnace body, the operator manually applies adhesive tape; when the joint passes through the furnace body, the heating function of the furnace body is temporarily suspended and the furnace door is opened for the joint to pass through; after the joint completely exits the furnace, the temperature of the furnace body is raised to the required temperature for the process (this temperature raising process takes about 1-2 minutes). However, this remedial measure has many drawbacks. On the one hand, since the heating is temporarily suspended and the temperature is raised again during the joint processing, at least 3 meters of chemical conversion foil product before and after the joint becomes waste, causing a certain amount of product loss; on the other hand, this operation increases the difficulty of the operator's work, and also exposes the operator to a high risk of burns and electric shock. SUMMARY

[0004] To solve the above technical problems, the technical solution adopted by the present application is: A sheet burning furnace device is provided, comprising a lower furnace body, an upper furnace body rotatably connected to the lower furnace body, and a central control module, a plurality of heating elements are arranged inside the lower furnace body, when the upper furnace body is covered on the lower furnace body, a heating cavity is formed between the upper furnace body and the lower furnace body, a first camera is arranged at the feeding side of the heating cavity, the first camera is connected to the upper furnace body, the first camera is electrically connected to the central control module, the central control module is individually electrically connected to each heating element for controlling the individual opening and closing of the heating elements.

[0005] The base is placed on the ground, before the foil is heated, the operator passes the foil through the lower furnace body, and covers the upper furnace body, the foil will continue to feed under the traction of the traction roller, the foil itself does not contact the foil furnace, the heating cavity is formed between the upper furnace body and the lower furnace body, the heating part located in the lower furnace body will heat the surface of the foil located in the heating cavity, with the feeding of the foil and the heating of the heating part, the temperature of the foil can be raised, the first camera located on the feeding side of the heating cavity can identify the joint of the foil, when the joint enters the heating cavity, the central control module will calculate the position of the joint according to the vehicle speed, and will close the heating part at the joint, and the remaining heating parts remain open, to ensure that the heating part does not heat the joint, the joint is not easy to break or tear due to high temperature environment, and it is not necessary to stop for processing at the joint, which improves the production efficiency and reduces the labor input, when the joint passes through the heating cavity, the central control module will restart the heating part to continue heating the aluminum foil.

[0006] Further, the heating part is an infrared heating pipe. The infrared heating pipe is a tubular heater using infrared principle. The infrared heating pipe can directly and efficiently transfer radiant heat to the surface of the irradiated foil, realize rapid heating, avoid energy loss caused by intermediate transmission medium, and significantly improve energy utilization efficiency.

[0007] Further, the heating part is perpendicular to the feeding direction of the foil, and all the heating parts are parallel and equidistant.

[0008] Further, the feeding side and the discharging side of the lower furnace body are rotationally connected with first roller shafts, and the feeding side and the discharging side of the upper furnace body are rotationally connected with second roller shafts. During the heating process of the foil, there is still a probability of foil breakage. When the foil is broken, the foil will move to both sides under the action of the pulling force and contact the first roller shaft and the second roller shaft, driving the first roller shaft and the second roller shaft to rotate, thereby effectively reducing the impact friction generated during the contact process of the foil with the machine after the foil is broken.

[0009] Further, the surface layers of the first roller shaft and the second roller shaft are made of insulating material. Since the foil is electrified, the voltage is 500-900V, the surface of the first roller shaft and the second roller shaft is made of insulating material, which is to prevent the electrified foil from touching the device after the foil is broken, causing the operator to be electrocuted, mainly playing a safety guarantee role.

[0010] Furthermore, the lower furnace body has a first ventilation pipe inside its shell that connects the heating chamber to the outside, and the upper furnace body has a second ventilation pipe inside its shell that connects the heating chamber to the outside. Air is injected into the heating chamber through the first or second ventilation pipe by an external fan. This removes moisture generated during heating, improving the efficiency and quality of the firing process, while reducing the risk of corrosion and damage to the equipment caused by moisture accumulation. Simultaneously, it effectively dissipates heat from the heating elements, controlling their operating temperature within a reasonable range, thereby extending their service life and ensuring the long-term stable operation of the firing furnace.

[0011] Furthermore, the first ventilation pipe is located below the heating pipe, and multiple first ventilation holes are provided at the top of the first ventilation pipe. The air inlet end of the first ventilation pipe extends to the bottom surface of the lower furnace body, and multiple second ventilation holes communicating with the second ventilation pipe are provided on the inner surface of the upper furnace body. The air outlet end of the second ventilation pipe extends to the top of the upper furnace body. The air inlet end of the first ventilation pipe is connected to an external fan. Gas enters the heating chamber through the first ventilation holes and enters the bottom of the heating element to dissipate heat from the heating element. The heated water vapor enters the second ventilation pipe through the second ventilation holes through the external exhaust fan and is discharged from the firing furnace.

[0012] Furthermore, the upper furnace body is equipped with a locking element, and the lower furnace body is equipped with a locking part. The locking element can be used to snap into the locking part. When the upper and lower furnace bodies are closed, the locking element can be pressed into the locking part, making the machine more stable.

[0013] Furthermore, a handle is provided on one side of the upper furnace body, and a counterweight is provided on the opposite side. The axis of rotation of the upper furnace body relative to the lower furnace body is located between the counterweight and the handle. The handle facilitates the operator in opening or closing the upper furnace body. Utilizing the lever principle, when the operator opens the upper furnace body, the weight of the counterweight makes it easier and less strenuous to open the upper furnace body.

[0014] Furthermore, the top of the upper furnace body is equipped with several temperature sensors for detecting the surface temperature of the foil. A second camera is installed on the discharge side of the heating chamber and connected to the upper furnace body. By detecting the surface temperature of the foil, operators can precisely control the temperature, thereby reducing the adverse effects of temperature fluctuations on the performance and quality of the foil. The second camera monitors and captures the surface color of the heated foil in real time to determine whether the foil humidity meets the standard. If it does not meet the standard, the data is fed back to the central control module to adjust the heating power of the heating elements.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. The first camera can identify the foil connector. The central control module will calculate the position of the connector based on the vehicle speed and turn off the heating element at the connector. The other heating elements will remain on to ensure that the heating elements will not heat the connector. The connector is not prone to cracking or breaking due to high temperature environment, and there is no need to stop the machine to process the connector. This improves production efficiency and reduces labor input. 2. Infrared heating tubes avoid energy loss caused by intermediate transmission media, significantly improving energy utilization efficiency; 3. The first and second rollers can effectively reduce the impact and friction generated when the foil comes into contact with the machine after the foil breaks. The surfaces of the first and second rollers are made insulated to prevent the charged foil from touching the device after the foil breaks, thus playing a safety role. 4. The installation of the first and second ventilation pipes serves two purposes: firstly, it removes the water vapor generated during heating, improving the efficiency and quality of the heating element and reducing the risk of corrosion and damage to the equipment caused by water vapor accumulation; secondly, it effectively dissipates heat from the heating element, keeping its operating temperature within a reasonable range and thus extending its service life.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0022] Example 1 This embodiment is a first embodiment of a sintering furnace apparatus, such as... Figure 1As shown, the furnace includes a base 100, a lower furnace body 200 mounted on the base 100, an upper furnace body 300 rotatably connected to the lower furnace body 200, and a central control module. The lower furnace body 200 contains 11 heating elements 400, which are arranged perpendicular to the foil feeding direction. All heating elements 400 are parallel and equidistant. When the upper furnace body 300 covers the lower furnace body 200, a non-sealed heating chamber is formed between the upper furnace body 300 and the lower furnace body 200. A first camera 500 and a second camera 600 are respectively installed on the feeding side and the discharge side of the heating chamber. Both the first camera 500 and the second camera 600 are fixed to the upper furnace body 300. A handle 350 and a locking element 340 are provided on the side of the upper furnace body 300 away from its own rotation axis. Figure 2 As shown, a counterweight 360 is provided on the opposite side. The rotation axis of the upper furnace body 300 is located between the counterweight 360 and the handle 350. The lower furnace body 200 is provided with a locking part 240. The locking part 340 can be used to snap together with the locking part 240. Three temperature sensors 370 are provided on the top of the upper furnace body 300. The temperature sensors 370 are used to detect the surface temperature of the foil. In this embodiment, the heating element 400 is an infrared heating tube, and the temperature sensors 370 are infrared temperature sensors.

[0023] The first camera 500 and the second camera 600 are electrically connected to the central control module, which is electrically connected to each heating element 400 individually to control the individual opening and closing of each heating element 400 and the adjustment of its power.

[0024] The working principle of this embodiment is as follows: In this invention, a foil-burning furnace apparatus is provided. The base 100 is placed on the ground. Before heating the foil, the operator passes the foil through the lower furnace body 200 and closes the upper furnace body 300, then fastens the locking member 340 onto the locking part 240. The foil is continuously fed under the traction of the traction roller, as shown in the following state. Figure 3As shown, the foil itself does not contact the firing furnace. The upper furnace body 300 and the lower furnace body 200 form a heating chamber. After the heating element 400 located in the lower furnace body 200 is turned on, it heats the surface of the foil located in the heating chamber. As the foil is fed in and the heating element 400 heats it, the foil can be heated. The first camera 500 located on the feeding side of the heating chamber can identify the foil joint. When the joint enters the heating chamber, the central control module will calculate the position of the joint based on the vehicle speed and turn off the heating element 400 at the joint. The other heating elements 400 remain on to ensure that the heating element 400 does not heat the joint. The joint is not prone to cracking or breaking due to the high temperature environment, and there is no need to stop. The machine processes the joint, improving production efficiency and reducing labor input. In addition, the first camera 500 can monitor and capture the color of the foil surface in real time, using the captured color data to accurately determine the humidity and dynamically control the heating power of the heating element 400, reducing energy consumption and effectively mitigating the potential impact of high temperature on the foil. After the joint passes through the heating chamber, the central control module will restart the heating element 400 to continue heating the aluminum foil. The second camera 600 monitors and captures the color of the heated foil surface in real time to determine whether the foil humidity meets the standard. If it does not meet the standard, it will feed back to the central control module to adjust the heating power of the heating element 400.

[0025] Furthermore, the number of heating elements 400 can be set to any number depending on the vehicle speed.

[0026] Example 2 This embodiment is a second embodiment of a sintering furnace apparatus. This embodiment is similar to the first embodiment, except that, as shown in the following... Figure 1 As shown, two first rollers 210 are rotatably connected to the feeding side and the discharging side of the lower furnace body 200, and a second roller 310 is rotatably connected to the feeding side and the discharging side of the upper furnace body 300. The axes of all the first rollers 210 and all the axes of all the second rollers 310 are parallel to each other. The surface of the first rollers 210 and the surface of the second rollers 310 are both made of insulating material. Here, the first rollers 210 and the second rollers 310 are ceramic rollers.

[0027] The working principle of this embodiment is as follows: During the heating process, there is still a chance that the foil will break. When the foil breaks, it will move to both sides under the pulling force and come into contact with the first roller 210 and the second roller 310, causing the first roller 210 and the second roller 310 to rotate. This can effectively reduce the impact and friction generated when the foil comes into contact with the machine after the foil breaks. Since the foil is charged with a voltage of 500-900V, the surfaces of the first roller 210 and the second roller 310 are made insulated to prevent the charged foil from touching the device after the foil breaks, which could cause electric shock to the operator. This mainly serves as a safety guarantee.

[0028] The remaining working principles of this embodiment are the same as those of Embodiment 1.

[0029] Example 3 This embodiment is a third embodiment of a sintering furnace apparatus. This embodiment is similar to embodiment two, except that, as shown in the example... Figure 1 As shown, the upper furnace body 300 has a first ventilation pipe 220 inside its shell, which connects the heating chamber to the outside. Figure 4 As shown, the lower furnace body 200 has a second ventilation pipe 320 inside its shell, connecting the heating chamber to the outside. Branch pipes of the first ventilation pipe 220 are located below each heating pipe, as shown below... Figure 5 As shown, the top of the first ventilation pipe 220 is provided with a plurality of first ventilation holes 230, the branch pipe of the first ventilation pipe 220 is connected to the main pipe, the air inlet end of the main pipe of the first ventilation pipe 220 extends to the bottom surface of the lower furnace body 200, the inner surface of the upper furnace body 300 is provided with a plurality of second ventilation holes 330 communicating with the second ventilation pipe 320, and the air outlet end of the second ventilation pipe 320 extends to the top of the upper furnace body 300.

[0030] The working principle of this embodiment is as follows: The air inlet of the first ventilation pipe 220 is connected to an external fan. Gas enters the heating chamber through the first ventilation hole 230 and enters the bottom of the heating element 400 to dissipate heat from the heating element 400. The heated water vapor enters the second ventilation pipe 320 through the second ventilation hole 330 through the external exhaust fan and is discharged from the firing furnace. On the one hand, it removes the water vapor generated by heating, improves the firing efficiency and quality, and reduces the risk of corrosion and damage to the equipment that may be caused by water vapor accumulation. On the other hand, it effectively dissipates heat from the heating element 400, controls the working temperature of the heating element 400 within a reasonable range, thereby extending the service life of the heating element 400 and ensuring the long-term stable operation of the firing furnace.

[0031] The remaining working principles of this embodiment are the same as those of Embodiment 2.

[0032] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0033] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make various variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
