Description

Technical Field

[0001] This invention relates to the field of propulsion feeding oven technology, and more particularly to an oven with a propulsion feeding structure. Background Technology

[0002] Box furnaces are mainly used in the heat treatment process in metal processing, involving processes such as annealing, quenching, and tempering. They are used in conjunction with material handling devices to pick up or feed the workpieces into the box furnace.

[0003] When the box furnace is in operation, the workpiece is first placed in the box furnace, the heating temperature and holding time are set according to the process requirements, and the box furnace is started to heat. For the quenching process of the workpiece, after the workpiece is heated to a suitable temperature and held, the workpiece is quickly sent into the quenching tank for cooling through the material handling mechanism. Then the processed workpiece is inspected for hardness, deformation, etc. to ensure that the processing effect meets the requirements.

[0004] However, this material handling device can cause local temperature drops in the furnace due to the moisture in the quenching pool evaporating after absorbing heat from the furnace. This disrupts the original uniform temperature in the furnace, resulting in uneven heating of metal in different areas and affecting the quality and consistency of metal heat treatment.

[0011] Preferably, a slot aligned with the rotating block is provided between the top and bottom of the lifting plate, a connecting shaft is rotatably connected to the side of the slot, and the other end of the connecting shaft is fixedly connected to the side of the rotating block. A motor slot aligned with the connecting shaft is provided on the side of the lifting plate, a second motor is fixedly connected to the side of the motor slot, a rotating shaft is fixedly connected to the output shaft of the second motor, and a chain is meshed between the circumferential side of the rotating shaft and the circumferential side of the connecting shaft.

[0012] Preferably, the bottom of the lifting plate is provided with at least two rotating slots, the top of the rotating slots is fixedly connected to a motor three, the output shaft of the motor three is fixedly connected to a rotating shaft, the circumferential side of the rotating shaft is fixedly connected to a support plate, the top of the support plate is rotatably connected to the top of the rotating slots, and one end of the support plate extends to the bottom of the rotating block.

[0013] Preferably, a rotating column is fixedly connected to one end of the connecting plate, and the two ends of the rotating column are rotatably connected to the inner walls of both sides of the air box. A movable column is fixedly connected to one end of the telescopic box, and the two ends of the movable column are slidably connected to the inner walls of both sides of the air box. A lifting block is slidably connected between the inner walls of both sides of the air box. The circumferential side of the movable column is rotatably connected to the side of the lifting block.

[0014] Preferably, a fixed plate aligned with the lifting block is fixedly connected between the inner walls of the two sides of the air box, the bottom of the lifting block abuts against the top of the fixed plate, a counterweight frame aligned with the lifting block is fixedly connected to the side of the movable frame, a connecting rope is fixedly connected to the top of the counterweight frame, and the other end of the connecting rope passes through the fixed plate and is fixedly connected to the bottom of the lifting block.

[0015] The beneficial effects of this invention are as follows: 1. The device is fixed above the quenching tank via a base frame using a set air box, and the moving frame is aligned with the box. The lifting tip plate is used to move the workpiece into or out of the box furnace. The heated workpiece is then immersed in the quenching tank by the lifting plate and the lifting tip plate to complete the quenching process. High-temperature airflow is blown evenly onto the lifting tip plate through the opening, allowing the high-temperature airflow to quickly dry the lifting tip plate. This helps prevent moisture from entering the box furnace with the device, absorbing heat from the furnace and evaporating, causing a local temperature drop in the furnace and disrupting the original uniform temperature in the box furnace. This results in uneven heating of metal in different areas, affecting the quality and consistency of metal heat treatment. At the same time, it can prevent moisture from causing rust and corrosion of metal components in the furnace, thereby improving the service life of the box furnace.

[0016] 2. By using the air box in conjunction with the high-temperature airflow to dry the rotating block and the lifting tip plate through the set support plate, the rotating block and the lifting tip plate are reset, so that the two support plates help to clamp and fix the rotating block, keeping the rotating block and the lifting tip plate in a vertical state. This is conducive to the high-temperature airflow contacting and drying all parts of the rotating block and the lifting tip plate, preventing the high-temperature airflow from failing to dry the moisture in the opposite airflow direction, resulting in a large amount of residual moisture on the device, which would affect the safety of subsequent material handling and feeding.

[0017] 3. The counterweight frame, when the rotating block rotates, lifts the counterweight frame. The counterweight frame releases the connecting rope, and the spring drives the lifting block to rise. The lifting block drives the connecting plate and telescopic box to rotate, so that the openings on both sides of the lifting block face the rotating block and the lifting tip plate. This allows the high-temperature airflow to be blown onto the rotating block and the lifting tip plate through the inclined openings when the rotating block and the lifting tip plate are vertical. This prevents some airflow from failing to contact the vertical rotating block and the lifting tip plate, which would reduce the efficiency of the device in drying the rotating block and the lifting tip plate and affect the working efficiency of the device.

[0020] Example 1, referring to Figure 1-7 A drying oven with a propulsion feeding structure includes a movable frame 1. A blower mechanism is provided on the side of the movable frame 1. The blower mechanism includes an air box 5 fixedly connected to the top of the side of the movable frame 1. At least two connecting plates 28 are rotatably connected between the bottom inner walls of the two sides of the air box 5. At least two telescopic boxes 27 aligned with the connecting plates 28 are rotatably connected between the bottom inner walls of the two sides of the air box 5. The bottom of the connecting plate 28 is slidably connected to the bottom inner wall of the telescopic box 27. Openings 29 are evenly provided between the top and bottom outer walls of the telescopic box 27 and between the top and bottom of the connecting plate 28. Springs 39 are evenly fixedly connected between one side of the connecting plate 28 and one side of the inner wall of the telescopic box 27. An air pipe 10 is fixedly connected between the top inner wall and the outer wall of the air box 5.

[0021] In this invention, a lifting plate 20 is slidably connected between the two inner walls of the movable frame 1, a rotating block 15 is rotatably connected to the side of the lifting plate 20, a lifting tip plate 14 is uniformly fixedly connected to the side of the rotating block 15, at least two fixed frames 3 are fixedly connected to the top of the movable frame 1, a motor 2 is fixedly connected to one side of the fixed frame 3, and a roller shaft 18 is fixedly connected to the output shaft of the motor 2.

[0022] A connecting cable 8 is fixedly wound around the circumferential side of roller 18. The other end of the connecting cable 8 passes through the movable frame 1 and is fixedly connected to the top of the lifting plate 20. At least two fixed frames 6 are fixedly connected to the top of the movable frame 1. A roller 7 is rotatably connected between one side of the two fixed frames 6. The connecting cable 8 abuts against the roller 7.

[0023] The bottom of the movable frame 1 is slidably connected to the base frame 2 17, the bottom of the base frame 2 17 is slidably connected to the base frame 1 16, the bottom of the base frame 2 17 is fixedly connected to the support frame 1 37 on both sides, the support frame 1 37 is fixedly connected to the motor 4 36 on one side, the output shaft of the motor 4 36 is fixedly connected to the circumferential side of the roller 1 38, and the circumferential side of the roller 1 38 abuts against the top of the base frame 1 16.

[0024] Support frame 2 33 is evenly fixedly connected to the bottom of the mobile frame 1. Motor 5 35 is fixedly connected to the side of support frame 2 33. Roller 2 34 is fixedly connected to the circumferential side of the output shaft of motor 5 35. The circumferential side of roller 2 34 abuts against the top of base frame 2 17.

[0025] In use of this invention: The device is fixed above the quenching tank by the base frame 16, and the movable frame 1 is aligned with the box furnace. Motors 4 (36) and 5 (35) are started. Motors 4 (36) and 5 (35) drive rollers 1 (38) and 2 (34) to rotate, thus moving the movable frame 1 forward, backward, left, and right. The movable frame 1 moves the lifting plate 20, which in turn moves the rotating block 15. The rotating block 15 moves the lifting tip plate 14, causing the lifting tip plate 14 to carry the workpiece into or out of the box furnace. After the lifting tip plate 14 carries the heated workpiece out of the box furnace, motor 1 (2) is started. Motor 1 (2) drives roller 18 to rotate. Roller 18 disconnects the connecting cable 8, and the connecting cable 8 disconnects the lifting tip plate 14. The lowering plate 20, lifting plate 20, and lifting tip plate 14 carry the heated workpiece into the quenching pool to complete the quenching process. The workpiece is then hoisted away from the device and high-temperature airflow is introduced into the air box 5 through the air inlet pipe 10. The high-temperature airflow is evenly blown onto the lifting tip plate 14 through the opening 29, which allows the high-temperature airflow to quickly dry the lifting tip plate 14. This helps to prevent moisture from entering the box furnace with the device, absorbing heat from the furnace and evaporating, causing a local temperature drop in the furnace and disrupting the original uniform temperature in the box furnace. This would result in uneven heating of metal in different areas, affecting the quality and consistency of metal heat treatment. At the same time, it can prevent moisture from causing rust and corrosion of metal components in the furnace, thereby improving the service life of the box furnace.

[0026] Example 2, refer to Figure 1-4 A baking oven with a pusher-type feeding structure includes a slot between the top and bottom of a lifting plate 20 that is aligned with a rotating block 15. A connecting shaft 19 is rotatably connected to the side of the slot, and the other end of the connecting shaft 19 is fixedly connected to the side of the rotating block 15. A motor slot 4 aligned with the connecting shaft 19 is opened on the side of the lifting plate 20. A second motor 9 is fixedly connected to the side of the motor slot 4. A rotating shaft 11 is fixedly connected to the output shaft of the second motor 9. A chain 12 is meshed between the circumferential side of the rotating shaft 11 and the circumferential side of the connecting shaft 19.

[0027] In this invention, the bottom of the lifting plate 20 is provided with at least two rotating grooves 23, the top of the rotating groove 23 is fixedly connected to a motor 21, the output shaft of the motor 21 is fixedly connected to a rotating shaft 22, the circumferential side of the rotating shaft 22 is fixedly connected to a support plate 24, the top of the support plate 24 is rotatably connected to the top of the rotating groove 23, and one end of the support plate 24 extends to the bottom of the rotating block 15.

[0028] When using this invention: When using the air box 5 in conjunction with high-temperature airflow to dry the lifting tip plate 14, start motor three 21. Motor three 21 drives the rotating shaft 22 to rotate, which in turn drives the support plate 24 to rotate, causing one support plate 24 to be inserted into the rotating groove 23. Then start motor two 9, which drives the rotating shaft 11 to rotate. The rotating shaft 11 drives the connecting shaft 19 to rotate via the chain 12. The connecting shaft 19 drives the rotating block 15 to rotate, which in turn drives the lifting tip plate 14 to rotate. The support plate 24 is then reset, allowing the two support plates 24 to assist in clamping and fixing the rotating block 15, keeping the rotating block 15 and the lifting tip plate 14 in a vertical position. This facilitates contact and drying of the high-temperature airflow with all parts of the rotating block 15 and the lifting tip plate 14, preventing the high-temperature airflow from failing to dry the moisture facing away from the airflow direction, which would result in a large amount of residual moisture on the device and affect the safety of subsequent material handling.

[0029] Example 3, referring to Figure 1-7 A furnace device with a propulsion feeding structure includes a connecting plate 28 with a rotating column 30 fixedly connected to one end, the two ends of the rotating column 30 being rotatably connected to the inner walls of the two sides of the gas box 5, a telescopic box 27 with a moving column 31 fixedly connected to one end, the two ends of the moving column 31 being slidably connected to the inner walls of the two sides of the gas box 5, a lifting block 40 being slidably connected between the inner walls of the two sides of the gas box 5, the circumferential side of the moving column 31 being rotatably connected to the side of the lifting block 40, and a spring 32 being fixedly connected between the top of the lifting block 40 and the top inner wall of the gas box 5.

[0030] In this invention, a fixing plate 26 aligned with the lifting block 40 is fixedly connected between the inner walls of both sides of the air box 5. The bottom of the lifting block 40 abuts against the top of the fixing plate 26. A counterweight frame 13 aligned with the lifting block 40 is fixedly connected to the side of the movable frame 1. A connecting rope 25 is fixedly connected to the top of the counterweight frame 13. The other end of the connecting rope 25 passes through the fixing plate 26 and is fixedly connected to the bottom of the lifting block 40.

[0031] When this invention is in use: when the rotating block 15 rotates, it drives the counterweight frame 13 to lift up. The counterweight frame 13 releases the connecting rope 25, and the spring 32 drives the lifting block 40 to rise. The lifting block 40 drives the connecting plate 28 and the telescopic box 27 to rotate, so that the openings 29 on both sides of the lifting block 40 face the rotating block 15 and the lifting tip plate 14. This is beneficial to ensure that when the rotating block 15 and the lifting tip plate 14 are vertical, the high-temperature airflow blows all of it onto the rotating block 15 and the lifting plate 14 through the inclined openings 29. This prevents some airflow from failing to contact the vertical rotating block 15 and the lifting tip plate 14, which would reduce the efficiency of the device in drying the rotating block 15 and the lifting tip plate 14 and affect the working efficiency of the device.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
