[0030] like Figure 1 and Figure 2 As shown, embodiment 1 provides a loading assembly for a heat treatment furnace 5 , including a material box 1 , a lifting mechanism 2 , a conveying mechanism 3 and a pushing mechanism 4 .

[0031] The bottom of the material box 1 includes two oppositely arranged bottom plates 11, and the sides of the two bottom plates 11 away from each other are rotatably connected to the side walls of the material box 1; wherein, when the two bottom plates 11 are in a first state, the bottom of the material box 1 is closed, and when the two bottom plates 11 are in a second state, the bottom of the material box 1 is open.

[0032] In practice, the material box 1 is designed as an open box, primarily used to hold castings to be heat treated. The bottom of the material box 1 is designed with two opposing bottom plates 11 (referred to as bottom plate A 11 and bottom plate B 11). These two bottom plates 11 are mounted to the side walls of the material box 1 via hinges or other pivoting connections. In the first state, the two bottom plates 11 are flush with the bottom of the material box 1, thus sealing the bottom of the material box 1. In the second state, the two bottom plates 11 are rotated to a position perpendicular to the horizontal plane of the bottom of the material box 1, opening the bottom of the material box 1.

[0033] In one possible implementation, Figure 2 As shown, for reference, two relatively arranged fixed plates 12 are further provided at the bottom of the material box 1, and the fixed plates 12 can be fixed to the side walls of the bottom of the material box 1 by welding or bolting. The two bottom plates 11 are located between the two fixed plates 12, and the fixed plates 12 abut against the side surfaces of the bottom plates 11; when the two bottom plates 11 are in the first state, the bottom of the material box 1 is closed, including: when the two bottom plates 11 are in the first state, the two fixed plates 12 and the two bottom plates 11 close the bottom of the material box 1.

[0034] like Figure 1As shown, the lifting mechanism 2 is located on one side of the heat treatment furnace 5, and a carrier 21 is provided on the lifting mechanism 2. The carrier 21 is used to carry the material box 1, and the carrier 21 is also used to limit the two bottom plates 11 so that the two bottom plates 11 are in the first state; the lifting mechanism 2 is used to lift the material box 1 to the side of the conveying mechanism 3.

[0035] Reference, such as Figure 3 As shown, the lifting mechanism 2 also includes a first driving member 22, a first transmission member 23 and a sliding member 24. The first driving member 22 is connected to the first transmission member 23, the first transmission member 23 is connected to the sliding member 24, and the sliding member 24 is connected to the object carrier 21. The first transmission member 23 is used to drive the sliding member 24 to move in the vertical direction, and the sliding member 24 is used to drive the object carrier 21 to move in the vertical direction.

[0036] It is understandable that if Figure 3 As shown, the lifting mechanism 2 includes a frame, the first driving member 22 is a motor, the first transmission member 23 includes a chain, a transmission shaft and a screw rod, the motor is arranged at the top of the frame, the output end of the motor is connected to the chain, the chain is connected to the transmission shaft, the transmission shaft is located in the horizontal direction, the end of the transmission shaft is provided with a gear, the screw rod is located in the vertical direction, the end of the screw rod is also provided with a gear, the gear at the end of the transmission shaft is meshed with the gear at the end of the screw rod, the sliding member 24 includes a sliding sleeve and a support plate, the sliding sleeve is provided on the screw rod, one side wall of the support plate is connected to the sliding sleeve, and the other side wall of the support plate is connected to the object carrier 21, and the object carrier 21 can be a metal object carrier.

[0037] It is understood that the width of the object carrier 21 is greater than the width of the fixed plate 12. When the material box 1 is placed on the object carrier 21, the object carrier 21 abuts against the bottom of the fixed plate 12. With this arrangement, when the material box 1 is placed on the object carrier 21, the object carrier 21 blocks the bottom plate 11 from rotating, causing the bottom of the material box 1 to open.

[0038] In this embodiment, after the motor is started, it rotates the drive shaft via a chain. As the drive shaft rotates, the gear at its end engages with the gear at the end of the lead screw, converting horizontal rotation into rotational motion of the lead screw. As the lead screw rotates, the sliding sleeve rises or falls along the length of the lead screw, driving the support plate and the metal carrier plate thereon to move together, thereby lifting or lowering the material bin 1. During the ascent, the carrier 21 maintains contact with the fixed plate 12, preventing the base plate 11 from rotating.

[0039] The conveying mechanism 3 includes a first conveying portion 31 and a second conveying portion 32 . The second conveying portion 32 is located above the feed port of the heat treatment furnace 5 .

[0040] Specifically, if Figure 4 As shown, for reference, the conveying mechanism 3 further includes a second driving member 33, a second transmission member 34, a third driving member 35, and a third transmission member 36; the second driving member 33 is connected to the second transmission member 34, the second transmission member 34 is connected to the first conveying portion 31, the third driving member 35 is connected to the third transmission member 36, and the third transmission member 36 is connected to the second conveying portion 32. The first conveying portion 31 is used to limit the two bottom plates 11 so that the two bottom plates 11 are in the first state; the first conveying portion 31 is also used to convey the material box 1 to the second conveying portion 32 so that the two bottoms are in the second state.

[0041] It is understandable that, Figure 4 As shown, the conveying mechanism 3 also includes a body, and the second driving member 33 is usually a motor, which is installed on one side of the body and serves as the power source of the first conveying part 31. The motor drives the movement of the first conveying part 31 through the second transmission member 34. The second transmission member 34 can be a chain, gear or other form of transmission device, which is used to transmit the power of the second driving member 33 (motor) to the first conveying part 31. The first conveying part 31 can be a conveyor belt, a roller or other form suitable for conveying the material box 1. The first conveying part 31 is responsible for conveying the material box 1 from the position of the lifting mechanism 2 to the position of the second conveying part 32. The width of the first conveying part 31 is greater than the width of the fixed plate 12. When the material box 1 is placed on the first conveying part 31, the bottom plate 11 is limited by the first conveying part 31 and is in a closed state.

[0042] The third driving member 35 is also a motor, installed on the other side of the machine body, and serves as the power source for the second conveying part 32. The motor drives the movement of the second conveying part 32 through the third transmission member 36. The third transmission member 36 can also be a chain, gear, etc., which is used to transmit the power of the third driving member 35 (motor) to the second conveying part 32; the second conveying part 32 includes two conveyor belts arranged opposite to each other, and the width of each conveyor belt is the same as the width of each fixed plate 12. When the material box 1 is conveyed to the second conveying part 32, the second conveying part 32 abuts against the fixed plate 12, and the second conveying part 32 does not contact the bottom plate 11. At this time, the bottom plate 11 is no longer subject to any limit. The bottom plate 11 rotates under the action of the gravity of the castings in the material box 1, so that the bottom of the material box 1 is in an open state, and the castings in the material box 1 fall into the feed port of the heat treatment furnace 5.

[0043] The pushing mechanism 4 is used to push the material box 1 onto the first conveying portion 31 .

[0044] Reference, such as Figure 1As shown, the pushing mechanism 4 includes a support member 41, a fourth driving member 42 and a telescopic member 43; the support member 41 is arranged on one side of the lifting mechanism 2, and a fourth driving member 42 is provided on the top of the support member 41, and the output end of the fourth driving member 42 is connected to the telescopic member 43, and the telescopic member 43 is used to push the material box 1 onto the first conveying part 31.

[0045] The support member 41 can be a support column. The height and position of the support member 41 need to be adjusted according to the specific positions of the lifting mechanism 2 and the first conveying section 31 to ensure that the telescopic member 43 can accurately push the material box 1 onto the first conveying section 31. The fourth driving member 42 is typically a pneumatic or hydraulic cylinder, mounted on the top of the support member 41, and serves as the power source for the telescopic member 43. The telescopic member 43 can be an actuator of the pneumatic or hydraulic cylinder, used to push the material box 1 from the position of the lifting mechanism 2 to the first conveying section 31.

[0046] In this embodiment, the material box 1 is placed on the object carrier 21 of the lifting mechanism 2. The width of the object carrier 21 is greater than the width of the fixed plate 12, ensuring that the bottom plate 11 will not open during the lifting process. The lifting mechanism 2 lifts the material box 1 to the side of the conveying mechanism 3, and the fourth driving member 42 is started, and the telescopic member 43 is extended by driving the material box 1 to be pushed from the position of the lifting mechanism 2 to the first conveying part 31. After the material box 1 is pushed to the first conveying part 31, the conveying mechanism 3 continues to convey the material box 1 to the position of the second conveying part 32, and finally opens the bottom plate 11, and the casting falls into the heat treatment furnace 5.

[0047] In summary, in this embodiment, the castings to be heat treated are loaded into the hopper 1. At this point, the bottom plates A and B of the hopper 1 are closed and in contact with the fixed plate 12, sealing the bottom of the hopper 1. The hopper 1, containing the castings, is then placed on the object carrier 21 of the lifting mechanism 2. The width of the object carrier 21 is greater than that of the fixed plate 12, ensuring contact between the object carrier 21 and the fixed plate 12, preventing rotation of the bottom plate 11. The lifting mechanism 2 is activated, and after the motor is started, the drive shaft rotates via a chain. As the drive shaft rotates, the gear at its end engages with the gear at the end of the lead screw, converting horizontal rotation into rotational motion of the lead screw. As the lead screw rotates, the sliding sleeve rises or descends along the length of the lead screw. The sliding sleeve drives the support plate and the metal loading plate above it to move together, thereby lifting or lowering the hopper 1. During the ascent, the object carrier 21 maintains contact with the fixed plate 12, preventing rotation of the bottom plate 11. The fourth drive member 42 (typically a pneumatic or hydraulic cylinder) is activated, driving the telescopic member 43 to extend. The telescopic member 43 pushes the material box 1 from the position of the lifting mechanism 2 to the first conveyor 31. After the material box 1 is pushed to the first conveyor 31, the bottom plate 11 is limited by the first conveyor 31 and remains closed. The second driving member 33 is activated, driving the first conveyor 31 to operate through the second transmission member 34. The first conveyor 31 conveys the material box 1 to the position of the second conveyor 32. When the material box 1 is conveyed to the second conveyor 32, the second conveyor 32 only contacts the fixed plate 12, and the bottom plate 11 is no longer limited. The bottom plate 11 rotates under the action of the gravity of the castings to be cast in the material box 1, causing the bottom of the material box 1 to be opened, and the castings in the material box 1 fall into the feed port of the heat treatment furnace 5.

[0048] By placing the material box on the load, and using the lifting mechanism to lift the material box filled with castings to the side of the conveying device, and then using the pushing mechanism to push the material box to the first conveying part, and finally using the conveying mechanism to send the material box to the second conveying part, the bottom plate is opened, and the castings automatically fall into the heat treatment furnace, realizing automatic loading.

[0049] By using mechanized lifting, conveying and pushing mechanisms to replace manual operations, it is especially possible to avoid manually opening the bottom plate of the material box in a high-temperature environment, reducing the risk of safety accidents such as burns caused by high temperatures during operation, and improving the safety factor of the operation.

[0050] The second embodiment provides a heat treatment furnace, comprising the loading assembly described in the first embodiment.

[0051] The above-described embodiments merely represent specific implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
