Description

Technical Field

[0001] This invention relates to the field of conveying technology, specifically to an anti-scratch output device for the degreasing process of aluminum radiator plates. Background Technology

[0002] In order to ensure quality, the raw materials of aluminum heat sinks are usually coated with volatile oil during the stamping process. After stamping, in order to remove the volatile oil, most factories will use a hot degreasing process, which involves placing the aluminum plate containing volatile oil in a furnace and then heating the aluminum plate with high-temperature gas at 235°C.

[0003] However, during the continuous high-temperature degreasing and conveying process at 235℃, aluminum plates containing volatile oils expand and wiggle within the furnace due to the heating effect of hot air. This causes them to rub against the stainless steel conveyor chain, resulting in various types of scratches on the workpiece surface and a low product qualification rate. Furthermore, degreasing furnaces on the market typically have hot gas exhaust and waste gas absorption devices. When the temperature is fixed, the degreasing efficiency can be improved by increasing the hot gas flow rate. At this time, the waste gas absorption device needs to simultaneously increase its absorption capacity. If the waste gas absorption device malfunctions at any point, causing the absorption capacity to not match the hot gas exhaust, the hot gas carrying grease in the degreasing furnace is highly likely to be released into the environment, causing pollution. Finally, when the hot gas exhaust device discharges hot gas, the radiator aluminum plate experiences a downward force. The faster the hot gas flow rate, the greater the downward force on the radiator aluminum plate. Since radiator aluminum plates are usually thin and have low hardness, the radiator is prone to dents and localized deformation. Summary of the Invention

[0004] The purpose of this invention is to provide a scratch-resistant output device for the degreasing process of aluminum heat sink plates, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an anti-scratch output device for the degreasing process of aluminum radiator plates. The output device is installed inside the furnace. A degreasing fan and a suction fan are installed above the furnace. The degreasing fan continuously delivers high-temperature gas into the furnace, and the suction fan continuously removes the high-temperature gas containing grease from the furnace. The output device includes a material conveying mechanism, a sealing mechanism, and a linear motor. A support is installed at the lower end of the furnace interior. The material conveying mechanism is mounted on the support and connected to the support via a slider and a groove. Two sets of sealing mechanisms are provided, respectively located at the inlet and outlet ends of the furnace. Two sets of linear motors are provided, respectively located at the outer ends of the furnace. The linear motors are connected to the material conveying mechanism and drive the material conveying mechanism to move within the furnace.

[0006] The furnace chamber serves as the installation base for this invention. Before operation, the sealing mechanism at the furnace inlet is opened, and the material conveying mechanism is moved by a linear motor. After the material conveying mechanism exits the furnace inlet, the radiator aluminum plate is placed on the material conveying mechanism. Then, the material conveying mechanism is moved again by the linear motor. When the material conveying mechanism is fully inside the furnace, the sealing mechanisms at the furnace inlet and outlet are closed. At this time, the degreasing fan and suction fan are turned on. The degreasing fan continuously delivers high-temperature gas at 235 degrees Celsius into the furnace to remove grease from the radiator aluminum plate. The suction fan removes the high-temperature gas containing grease after use to ensure that the high-temperature gas in the furnace remains clean, thereby improving degreasing efficiency. After degreasing is completed, the degreasing fan and suction fan are turned off, and the sealing mechanism at the furnace outlet is opened. Then, the material conveying mechanism is moved out of the furnace outlet by a linear motor for easy handling by personnel.

[0007] Furthermore, the material conveying mechanism includes a material conveying seat, a chain, and a track. The track is disposed on the material conveying seat, the chain is disposed inside the track, a flap is disposed on the chain, and PTFE anti-scratch nails are disposed on the flap.

[0008] The present invention features a stainless steel track with expansion grooves, which allows the chain to move smoothly and without jamming during the heating and expansion process within the 235-degree furnace. Simultaneously, the chain is equipped with flaps, on which custom-made PTFE anti-scratch studs are installed. The aluminum radiator workpiece is placed on the conveyor chain fitted with PTFE anti-scratch studs and enters the 235-degree furnace where the aluminum expands and creeps. The contact between the workpiece surface and the PTFE anti-scratch studs prevents scratches or damage to the aluminum surface, thus improving product quality and production efficiency.

[0009] Furthermore, the support is equipped with a balancing fan, the material conveying seat is equipped with a through hole, the upper end of the flap is equipped with a groove, the inside of the groove is equipped with a piezoelectric sheet, the PTFE anti-scratch nail is equipped with a top rod near the end of the groove, and the piezoelectric sheet is connected to the balancing fan.

[0010] When the temperature is fixed, the degreasing efficiency can be improved by increasing the flow rate of the high-temperature gas. However, the thickness of the radiator aluminum plate is usually only a few millimeters. If the radiator aluminum plate is subjected to a large downward force, the unsupported areas of the radiator aluminum plate are likely to dent and deform. At the same time, the area where the radiator aluminum plate contacts the PTFE anti-scratch nail will also undergo local deformation. Therefore, this invention is equipped with a balancing fan and a piezoelectric sheet is installed inside the groove. When the radiator aluminum plate is subjected to a downward force, it will squeeze the PTFE anti-scratch nail, thereby causing the push rod to apply pressure to the piezoelectric sheet. The magnitude of the electrical signal generated by the piezoelectric sheet can be used to determine the magnitude of the pressure on the radiator aluminum plate. When the pressure on the radiator aluminum plate is small, the balancing fan sprays low-speed high-temperature gas. When the pressure on the radiator aluminum plate is large, the balancing fan sprays high-speed high-temperature gas. The high-temperature gas generated by the balancing fan can balance the downward force on the radiator aluminum plate, ensuring that the quality of the radiator aluminum plate is not affected while improving the degreasing efficiency.

[0011] Furthermore, the sealing mechanism includes a sealing frame, a sealing plate, a start / stop motor, a start / stop assembly, and a compensation assembly. An output channel is provided at the middle position of the sealing frame. A telescopic groove is provided at the upper end of the sealing frame, away from the balancing fan. A transmission groove is provided at the upper end of the sealing frame, near the balancing fan. One end of the sealing plate is located within the telescopic groove, and the other end extends out of the telescopic groove. The start / stop motor, the start / stop assembly, and the compensation assembly are all located within the transmission groove. The start / stop motor drives the sealing plate to move within the telescopic groove via the start / stop assembly. The start / stop motor controls the gas pressure inside the furnace via the compensation assembly.

[0012] During feeding or discharging, the opening and closing motor drives the sealing plate to move into the telescopic groove via the opening and closing assembly. When the furnace needs to be completely sealed, the opening and closing motor drives the sealing plate out of the telescopic groove via the opening and closing assembly, blocking the output channel. Finally, the invention also includes a compensation assembly. The opening and closing motor controls the air pressure inside the furnace via the compensation assembly to ensure that the air pressure inside the furnace remains constant. Through the above technical solution, on the one hand, it prevents the exhaust gas absorption from failing to match the high-temperature gas emission at a certain moment due to a malfunction of the suction fan, which would cause the high-temperature gas carrying grease in the furnace to be emitted to the outside and pollute the external environment. On the other hand, it avoids the degreasing fan stopping before the suction fan after the work is completed, which would cause a negative pressure environment in the furnace, and thus cause the gas containing impurities in the outside to enter the furnace under the action of air pressure, polluting the internal environment of the furnace.

[0013] Furthermore, a buffer groove is provided at the lower end of the sealing frame near the sealing plate, and a sealing block is provided inside the buffer groove. The sealing block and the buffer groove are connected by a buffer spring, and a metal resistor block is provided at the end of the sealing block away from the sealing plate.

[0014] When the sealing plate exits and falls from the telescopic groove, the sealing block and buffer spring prevent the sealing frame from directly colliding with the lower end of the output channel, thus reducing the risk of wear. At the same time, since temperature affects the resistance value of the metal resistance block, when wear occurs in the buffer groove part of the sealing frame, hot air in the furnace will enter the buffer groove and come into contact with the metal resistance block. By detecting the change in the resistance value of the metal resistance block, it can be determined whether the furnace is in a sealed state. The resistance value of the metal resistance block can be detected using existing technology, such as connecting the metal resistance block to an external power supply and an ammeter, and detecting the change in current on the ammeter, or using a multimeter or other equipment.

[0015] Furthermore, the sealing plate has an air chamber and a sensing groove inside, both of which are filled with gas and connected to each other. A flexible plate is provided at the end of the air chamber near the balancing fan, and a sensing plate and a sensing spring rod are provided inside the sensing groove.

[0016] In this invention, a set of conductive plates is provided on both the induction plate and the induction spring rod. One set of conductive plates is connected to an external power source, and the other set is connected to an ammeter. Simultaneously, a circuit is formed between the two sets of conductive plates, the external power source, and the ammeter. During the degreasing process of the aluminum heat sink plate, if the gas pressure inside the furnace suddenly decreases, the induction spring on the induction spring rod will push the induction plate towards the air guide hole. At this time, the distance between the two sets of conductive plates will change, and the current on the ammeter will also change synchronously. The change in current on the ammeter can indicate the extent of the decrease in gas pressure inside the furnace, allowing the operator to compensate for gas in the furnace using the compensation component. Similarly, if the gas pressure inside the furnace suddenly increases, the induction plate will move away from the air guide hole under the influence of the gas pressure, and the distance between the two sets of conductive plates will still change. The operator can then remove excess gas from the furnace using the compensation component. Finally, in this invention, both the sealing plate and the flexible plate are made of heat-insulating material, thereby improving the accuracy of detecting changes in gas pressure inside the furnace.

[0017] Furthermore, the opening and closing assembly includes a driven gear and a winding reel. The opening and closing motor is connected to the driven gear via a driving gear. The driven gear is connected to the transmission groove via a first connecting shaft. The winding reel is connected to the transmission groove via a second connecting shaft. A transmission cavity is provided at the end of the winding reel near the driven gear. Two sets of movable grooves are provided at the end of the first connecting shaft near the winding reel. Each set of movable grooves contains a set of movable blocks. The two sets of movable blocks are connected by a double-headed cylinder. A transmission rope is wound on the winding reel, and the winding reel is connected to the sealing plate via the transmission rope.

[0018] Under normal circumstances, the double-headed cylinder drives two sets of movable blocks to move and make close contact with the transmission cavity. Through friction, the first connecting shaft and the winding wheel can rotate synchronously. If the start-stop motor drives the drive gear to rotate, the first connecting shaft and the winding wheel will rotate synchronously under the action of the drive gear and the driven gear to achieve the purpose of controlling the lifting and lowering of the sealing plate. In abnormal circumstances (i.e., the gas pressure in the furnace is too high or too low, so that the compensation component needs to be activated), the double-headed cylinder drives the two sets of movable blocks to retract into the movable groove. At this time, even if the driven gear rotates, it will not drive the winding wheel to rotate, thus achieving the purpose of separation and ensuring that the furnace is always in a sealed state when adjusting the gas pressure in the furnace.

[0019] Furthermore, a filter is provided above the furnace chamber, and the compensation assembly includes a compensation frame, a piston, and a gear disk. The piston and gear disk are both located inside the compensation frame. The start-stop motor is connected to the gear disk via a drive gear, and the gear disk is connected to the piston via a connecting rod. The compensation frame has a first port and a second port near the output channel. Both the first port and the second port are equipped with one-way valves. The first port is connected to the filter via a conduit.

[0020] The one-way valve in this invention is an electric one-way valve. When the gas pressure inside the furnace is high, the one-way valve on the first port is in a one-way exhaust state, and the one-way valve on the second port is in a one-way intake state. The start-stop motor drives the gear disk to rotate through the drive gear. At this time, the gear disk drives the piston to move inside the compensation frame through the connecting rod. The piston draws the gas inside the furnace into the compensation frame, and then discharges it to the outside through the first port and the filter. When the furnace is under negative pressure, the one-way valve on the first port is in a one-way intake state, and the one-way valve on the second port is in a one-way exhaust state. Similarly, when the start-stop motor is turned on, the start-stop motor and the drive gear drive the gear disk to rotate. The piston draws the outside gas into the furnace after it has been processed by the filter, so as to achieve the purpose of balancing the gas pressure inside the furnace.

[0021] Compared with existing technologies, the beneficial effects achieved by this invention are as follows: Compared with current degreasing output devices for aluminum radiator plates, this invention can effectively solve the problem that aluminum plates expand and creep inside the furnace due to heating by hot air, causing hard friction with the stainless steel conveyor chain, which leads to different types of scratches on the workpiece surface, thus ensuring the degreasing effect. In addition, this invention also includes a sealing plate and a compensation component. The sealing plate ensures that the furnace chamber remains sealed during the degreasing process of the aluminum radiator plate, while detecting whether the gas pressure inside the furnace is abnormal. The compensation component controls the gas pressure inside the furnace to ensure that the gas pressure inside the furnace remains constant. This prevents the exhaust gas absorption from failing to match the high-temperature gas emission due to a malfunction of the suction fan at a certain moment. This would cause high-temperature gases carrying grease to be released into the furnace, polluting the external environment. On the other hand, to prevent the degreasing fan from stopping before the suction fan after the work is completed, which would create a negative pressure environment in the furnace and allow external gases containing impurities to enter the furnace under pressure, polluting the internal environment, this invention is equipped with a balancing fan and piezoelectric plates in the grooves of the flaps. The high-temperature gases generated by the balancing fan can balance the downward force on the radiator aluminum plate, preventing dents and deformations in unsupported areas of the radiator aluminum plate, and preventing localized deformation in the area where the radiator aluminum plate contacts the PTFE anti-scratch nails. This ensures that the quality of the radiator aluminum plate is not affected while improving degreasing efficiency. Attached Figure Description

Detailed Implementation

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] like Figures 1-3 and Figure 6As shown, an anti-scratch output device for the degreasing process of aluminum radiator plates is provided. The output device is installed inside the furnace chamber 1. A degreasing fan 3 and a suction fan 4 are installed above the furnace chamber 1. The degreasing fan 3 continuously delivers high-temperature gas into the furnace chamber 1, and the suction fan 4 continuously sucks away the high-temperature gas containing grease from the furnace chamber 1. The output device includes a material conveying mechanism 2, a sealing mechanism 6, and a linear motor 7. A support 11 is provided at the lower end of the furnace chamber 1. The material conveying mechanism 2 is installed on the support 11 and is connected to the support 11 by a slider and a groove. Two sets of sealing mechanisms 6 are provided, which are respectively located at the inlet and outlet ends of the furnace chamber 1. Two sets of linear motors 7 are provided, which are respectively located at the outer ends of the furnace chamber 1. The linear motors 7 are connected to the material conveying mechanism 2 and drive the material conveying mechanism 2 to move inside the furnace chamber 1.

[0038] The furnace chamber 1 serves as the installation base for this invention. Before operation, the sealing mechanism 6 at the inlet end of the furnace chamber 1 is opened, and the material conveying mechanism 2 is moved by the linear motor 7. After the material conveying mechanism 2 exits from the inlet end of the furnace chamber 1, the radiator aluminum plate is placed on the material conveying mechanism 2. Then, the material conveying mechanism 2 is moved again by the linear motor 7. When the material conveying mechanism 2 is fully inside the furnace chamber 1, the sealing mechanisms 6 at the inlet and outlet ends of the furnace chamber 1 are closed. At this time, the degreasing fan 3 and the suction fan 4 are turned on. The degreasing fan 3 continuously delivers high-temperature gas of 235 degrees Celsius into the furnace chamber 1 to remove grease from the radiator aluminum plate. The suction fan 4 sucks away the high-temperature gas containing grease after use to ensure that the high-temperature gas in the furnace chamber 1 is always clean, thereby improving the degreasing efficiency. After degreasing is completed, the degreasing fan 3 and the suction fan 4 are turned off, and the sealing mechanism 6 located at the outlet end of the furnace chamber 1 is opened. Then, the material conveying mechanism 2 is moved out from the outlet end of the furnace chamber 1 by the linear motor 7 for easy handling by the staff.

[0039] like Figures 1-5 As shown, the material conveying mechanism 2 includes a material conveying seat 21, a chain 22 and a track 23. The track 23 is set on the material conveying seat 21, the chain 22 is set inside the track 23, a flap 222 is set on the chain 22, and a PTFE anti-scratch nail 221 is set on the flap 222.

[0040] The track 23 of this invention is a stainless steel track with expansion grooves, which makes the chain 22 move smoothly and without jamming when heated and expanded in the furnace 1 at 235 degrees Celsius. At the same time, the chain 22 is equipped with a flap 222, on which a customized PTFE anti-scratch nail 221 is installed. The aluminum heat sink workpiece is placed on the conveyor chain 22 equipped with PTFE anti-scratch nail 221 and enters the furnace 1 at 235 degrees Celsius. The aluminum expands and creeps, and the contact between the workpiece surface and the PTFE anti-scratch nail 221 will not cause scratches or damage to the aluminum plate surface, thus improving product quality and production efficiency.

[0041] like Figures 1-4 , Figure 6 As shown, a balancing fan 12 is installed inside the support 11. The balancing fan 12 generates high-temperature gas at the same temperature as the degreasing fan 3. The material conveying seat 21 is provided with a through hole. The upper end of the flip plate 222 is provided with a groove. A piezoelectric sheet 2221 is provided inside the groove. A top rod 2211 is provided at one end of the PTFE anti-scratch nail 221 near the groove. The operation of the balancing fan 12 is controlled by the piezoelectric sheet 2221. The balancing fan 12 is connected to an external power source.

[0042] When the temperature is constant, the degreasing efficiency can be improved by increasing the flow rate of the high-temperature gas. However, the thickness of the radiator aluminum plate is usually only a few millimeters. If the radiator aluminum plate is subjected to a large downward force, the unsupported areas of the radiator aluminum plate are likely to dent and deform. At the same time, the area where the radiator aluminum plate contacts the PTFE anti-scratch nail 221 will also undergo local deformation. Therefore, this invention is equipped with a balancing fan 12 and a piezoelectric sheet 2221 is arranged inside the groove. When the radiator aluminum plate is subjected to a downward force, it will squeeze the PTFE anti-scratch nail 221, thus preventing further degreasing. The push rod 2211 applies pressure to the piezoelectric sheet 2221. The magnitude of the electrical signal generated by the piezoelectric sheet 2221 can determine the pressure on the radiator aluminum plate. When the pressure on the radiator aluminum plate is small, the balancing fan 12 sprays low-speed high-temperature gas. When the pressure on the radiator aluminum plate is large, the balancing fan 12 sprays high-speed high-temperature gas. The high-temperature gas generated by the balancing fan 12 can balance the downward force on the radiator aluminum plate, so as to ensure that the quality of the radiator aluminum plate is not affected while improving the degreasing efficiency.

[0043] like Figures 1-2 , Figure 6 and Figure 8 As shown, the sealing mechanism 6 includes a sealing frame 61, a sealing plate 62, a start-stop motor 63, a start-stop assembly 64, and a compensation assembly 65. An output channel is provided at the middle position of the sealing frame 61. A telescopic groove 611 is provided at the upper end of the sealing frame 61 away from the balancing fan 12. A transmission groove is provided at the upper end of the sealing frame 61 near the balancing fan 12. One end of the sealing plate 62 is located in the telescopic groove 611, and the other end of the sealing plate 62 extends out of the telescopic groove 611. The start-stop motor 63, the start-stop assembly 64, and the compensation assembly 65 are all located in the transmission groove. The start-stop motor 63 controls the gas pressure inside the furnace 1 through the compensation assembly 65.

[0044] During feeding or discharging, the opening and closing motor 63 drives the sealing plate 62 to move into the telescopic groove 611 through the opening and closing component 64. When the furnace 1 needs to be completely sealed, the opening and closing motor 63 drives the sealing plate 62 to move out of the telescopic groove 611 through the opening and closing component 64 and blocks the output channel. Finally, the present invention is also provided with a compensation component 65. The opening and closing motor 63 controls the air pressure inside the furnace 1 through the compensation component 65 to ensure that the air pressure inside the furnace 1 is always constant. Through the above technical solution, on the one hand, it prevents the exhaust gas absorption from failing to match the high-temperature gas emission at a certain moment due to the failure of the suction fan 4, which would cause the high-temperature gas carrying grease in the furnace 1 to be emitted to the outside and pollute the external environment. On the other hand, it avoids the degreasing fan 3 stopping before the suction fan 4 after the work is completed, which would cause a negative pressure environment in the furnace 1, which would cause the gas containing impurities in the outside to enter the furnace 1 under the action of air pressure and pollute the internal environment of the furnace 1.

[0045] like Figure 8 As shown, a buffer groove is provided at the lower end of the sealing frame 61 near the sealing plate 62. A sealing block is provided inside the buffer groove. The sealing block and the buffer groove are connected by a buffer spring. A metal resistor block is provided at the end of the sealing block away from the sealing plate 62.

[0046] When the sealing plate 62 exits from the telescopic groove 611 and falls, the sealing block and buffer spring prevent the sealing frame 61 from directly colliding with the lower end of the output channel, thereby reducing the risk of wear. At the same time, since temperature affects the resistance value of the metal resistance block, when wear occurs in the buffer groove part on the sealing frame 61, the hot air in the furnace 1 will enter the buffer groove and come into contact with the metal resistance block. By detecting the change in the resistance value of the metal resistance block, it can be determined whether the furnace 1 is in a sealed state. The resistance value of the metal resistance block can be detected using existing technology, such as connecting the metal resistance block to an external power supply and an ammeter, and detecting the change in current on the ammeter, or using a multimeter or other equipment.

[0047] like Figures 8-10 As shown, the sealing plate 62 has an air chamber 621 and a sensing groove 623 inside. Both the air chamber 621 and the sensing groove 623 are filled with gas and are connected through an air guide hole. A flexible plate 622 is provided at the end of the air chamber 621 near the balancing fan 12. A sensing plate 624 and a sensing spring rod are provided inside the sensing groove 623.

[0048] In this invention, a set of conductive plates is provided on the induction plate 624 and the induction spring rod. One set of conductive plates is connected to an external power source, and the other set of conductive plates is connected to an ammeter. At the same time, the two sets of conductive plates, the external power source, and the ammeter form a circuit. During the degreasing process of the aluminum heat sink plate, if the gas pressure in the furnace chamber 1 suddenly decreases, the induction spring on the induction spring rod will push the induction plate 624 to move towards the air guide hole. At this time, the distance between the two sets of conductive plates will change, and the current on the ammeter will also change synchronously. The change in current on the ammeter can determine the extent of the decrease in gas pressure in the furnace chamber 1, so that the operator can compensate the gas in the furnace chamber 1 through the compensation component 65. Similarly, if the gas pressure in the furnace chamber 1 suddenly increases, the induction plate 624 will move away from the air guide hole under the action of the gas pressure. The distance between the two sets of conductive plates will still change. At this time, the operator can remove the excess gas in the furnace chamber 1 through the compensation component 65. Finally, in this invention, both the sealing plate 62 and the flexible plate 622 are made of heat-insulating material, thereby improving the accuracy of detecting changes in gas pressure in the furnace chamber 1.

[0049] like Figure 8 , Figures 11-12 As shown, the opening and closing assembly 64 includes a driven gear 641 and a take-up reel 642. The opening and closing motor 63 is connected to the driven gear 641 via the driving gear 631. The driven gear 641 is connected to the transmission groove via the first connecting shaft 6411. The take-up reel 642 is connected to the transmission groove via the second connecting shaft 6421. A transmission cavity is provided at one end of the take-up reel 642 near the driven gear 641. Two sets of movable grooves are provided at one end of the first connecting shaft 6411 near the take-up reel 642. Each set of movable grooves contains a set of movable blocks 6412. The two sets of movable blocks 6412 are connected by a double-headed cylinder 6413. A transmission rope is wound on the take-up reel 642. The take-up reel 642 is connected to the sealing plate 62 via the transmission rope.

[0050] Under normal circumstances, the double-headed cylinder 6413 drives the two sets of movable blocks 6412 to move and make close contact with the transmission cavity. Through friction, the first connecting shaft 6411 and the winding wheel 642 can rotate synchronously. If the start-stop motor 63 drives the drive gear 631 to rotate, the first connecting shaft 6411 and the winding wheel 642 will rotate synchronously under the action of the drive gear 631 and the driven gear 641 to achieve the purpose of controlling the lifting and lowering of the sealing plate 62. In abnormal circumstances (i.e., the gas pressure in the furnace 1 is too high or too low, so that the compensation component 65 needs to be opened), the double-headed cylinder 6413 will drive the two sets of movable blocks 6412 to retract into the movable groove. At this time, even if the driven gear 641 rotates, it will not drive the winding wheel 642 to rotate, thereby achieving the purpose of separation and ensuring that the furnace 1 is always in a sealed state when adjusting the gas pressure in the furnace 1.

[0051] like Figure 8 , Figures 11-12 As shown, a filter 5 is installed above the furnace 1. The compensation assembly 65 includes a compensation frame 651, a piston 652, and a gear disk 653. Both the piston 652 and the gear disk 653 are installed inside the compensation frame 651. The start-stop motor 63 is connected to the gear disk 653 through a drive gear 631. The gear disk 653 is connected to the piston 652 through a connecting rod. A first port and a second port are provided at one end of the compensation frame 651 near the output channel. Both the first port and the second port are equipped with a one-way valve. The first port is connected to the filter 5 through a conduit.

[0052] The one-way valve in this invention is an electric one-way valve. When the gas pressure inside the furnace 1 is high, the one-way valve on the first port is in a one-way exhaust state, and the one-way valve on the second port is in a one-way intake state. The start-stop motor 63 drives the gear disk 653 to rotate through the drive gear 631. At this time, the gear disk 653 drives the piston 652 to move inside the compensation frame 651 through the connecting rod. The piston 652 draws the gas inside the furnace 1 into the compensation frame 651, and then discharges it to the outside through the first port and the filter 5. When the furnace 1 is under negative pressure, the one-way valve on the first port is in a one-way intake state, and the one-way valve on the second port is in a one-way exhaust state. Similarly, the start-stop motor 63 is turned on, and the start-stop motor 63 and the drive gear 631 drive the gear disk 653 to rotate. The piston 652 draws the outside gas into the furnace 1 after it has been processed by the filter 5, so as to achieve the purpose of balancing the gas pressure inside the furnace 1.

[0053] The working principle of this invention is as follows: Before operation, the sealing mechanism 6 at the inlet end of the furnace 1 is opened, and the material conveying mechanism 2 is moved by the linear motor 7. After the material conveying mechanism 2 exits from the inlet end of the furnace 1, the radiator aluminum plate is placed on the material conveying mechanism 2. Then, the material conveying mechanism 2 is moved again by the linear motor 7. When the material conveying mechanism 2 has completely entered the furnace 1, the sealing mechanism 6 at the inlet and outlet ends of the furnace 1 is closed. At this time, the degreasing fan 3 and the suction fan 4 are turned on, and the degreasing fan 3 continuously delivers high-temperature gas of 235 degrees Celsius into the furnace 1. To remove grease from the aluminum plate of the radiator, the high-temperature gas containing grease after use is sucked away by the suction fan 4 to ensure that the high-temperature gas in the furnace 1 is always clean, thereby improving the degreasing efficiency. After the degreasing work is completed, the gas pressure inside the furnace 1 is controlled by the start and stop motor 63 and the compensation component 65 to ensure that the gas pressure inside the furnace 1 is always constant. When the gas pressure inside the furnace 1 is stable, the sealing mechanism 6 located at the outlet end of the furnace 1 is opened, and then the material conveying mechanism 2 is moved out from the outlet end of the furnace 1 by the linear motor 7 for easy handling by the staff.
