[0031] The heating device includes a first baffle assembly 61 and a second baffle assembly 63, wherein the first baffle assembly 61 and the second baffle assembly 63 respectively cooperate with the heat-insulating support frame 612 to realize the formation of the melting cavity 62. When in use, when the side of the melt box 4 passes through the second baffle assembly 63 and enters the interior of the melting cavity 62, the second baffle assembly 63 returns to its original position, and the heating equipment inside the heat-insulating support frame 612 is used to fully heat the melt box 4 again to ensure that the interior of the melt box 4 can be fully heated, so as to continue to convey the obtained melt box 4. At this time, the first baffle assembly 61 is opened to enable the obtained melt box 4 to be unloaded. In this process, when the first baffle assembly 61 is opened, the second baffle assembly 63 is squeezed and pushed open by the next group of melt boxes 4 to realize the circulation of gas, thereby ensuring the stability of the air pressure inside the melting cavity 62.

[0034] The adjustment assembly 24 includes a first mounting plate 241 and a second mounting plate 243, wherein the first mounting plate 241 and the second mounting plate 243 are fixedly connected via a limiting slide column 242, a retracting roller is mounted on the second mounting plate 243, and the second mounting plate 243 is fixedly mounted on a traction power support plate 245, the traction power support plate 245 is slidably connected to the sliding limiting groove 23, the rotation of the retracting roller is used to realize the reeling function of the traction rope 244, wherein the other end of the traction rope 244 is fixedly mounted on a limiting slide bar 247, and a limiting plate 246 is fixed on the side of the first mounting plate 241, The limit plate 246 and the limit slide bar 247 are slidably connected. When in use, the rotation of the retractable roller is used to control the reeling of the traction rope 244, so as to control the height of the limit plate 246, thereby controlling the height of the interval adjustment mechanism 3 installed at the end of the limit plate 246, so that the interval adjustment mechanism 3 can be moved away from between adjacent melt boxes 4, and the interval adjustment mechanism 3 can be recycled through the top conveying plate 22, ensuring that each adjacent melt box 4 is separated by the interval adjustment mechanism 3, ensuring that there is a certain gap between the melt boxes 4, so as to ensure that it can be fully exposed to the heat source and ensure its melting effect.

[0035] Therefore, the interval adjustment mechanism 3 includes a fixed base plate 31, and adjacent fixed base plates 31 are fixedly connected by a supporting base plate, and the fixed base plate 31 and the supporting base plate are installed in an I-shape, and a supporting mounting seat 37 is fixedly installed on the fixed base plate 31, which is used to be fixedly connected to the limiting slide bar 247, so as to control the overall height of the interval adjustment mechanism 3, wherein two-way push rods 39 are symmetrically arranged on the supporting base plate through a power device, that is, the power device is used to control the distance between adjacent two-way push rods 39, and a push plate mounting plate 34 is fixed at the output end of the two-way push rod 39, so when the two-way push rod 39 moves toward or away from each other, the distance between adjacent push plate mounting plates 34 can be controlled, so that the angle between the first push plate 32 and the second push plate 33 rotatably mounted on the push plate mounting plate 34 can be adjusted, that is, the first push plate 32 and the second push plate 33 are both rotatably mounted on the push plate mounting plate 34 by a torsion spring, and the first push plate 32 and the second push plate 33 are respectively squeezed on the sides of the two melt boxes 4 When the power equipment drives the adjacent two-way push rods 39 to move toward each other, under the action of the torsion spring, the side walls of the melt box 4 are subjected to the pressure of movement, and a limited sliding groove 38 is opened on the fixed bottom plate 31, and a cross-rotating rod 36 is arranged on the supporting bottom plate through the rotation of the torsion spring, wherein the end of the cross-rotating rod 36 is rotatably mounted on the end seat, and the end seat is slidably connected with the clamping push plate 35, and the cross-rotating rod 36 and the push plate mounting plate 34 are used in coordination, that is, when the power equipment drives the two-way push rod 39 to move, the push plate mounting plate 34 moves toward each other, and the cross-rotating rod 36 is squeezed at this time, so that the adjacent clamping push plates 35 can move back to back, thereby pushing the bottom of the melt box 4, so that the distance between the melt boxes 4 can be adjusted. At the same time, due to the action of the first push plate 32 and the second push plate 33, the side of the melt box 4 can also maintain a certain thrust under a certain height state, thereby ensuring its stability and realizing the adjustment of the distance between adjacent melt boxes 4. In this technical solution, the power device is gas-driven to control the two-way push rod 39 to move toward or away from each other.

Specifically, when the power equipment drives the two-way push rod 39 to move, the push plate mounting plates 34 move toward each other, and the cross The fork rotating rod 36 is squeezed so that the adjacent clamping push plates 35 can move back to back, thereby pushing the bottom of the melt box 4, so that the distance between the melt boxes 4 can be adjusted. At the same time, due to the action of the first push plate 32 and the second push plate 33, the side of the melt box 4 can also maintain a certain thrust at a certain height state, ensuring its stability and realizing the adjustment of the distance between adjacent melt boxes 4. The melt box 4 enters the interior of the melting cavity 62, and the reheating equipment is used to reheat the melt box 4 inside the melting cavity 62. Then, when the guide roller 51 continues to start, the melt box 4 is pushed out of the melting cavity 62 through the first baffle assembly 61, and is pushed out of the heat treatment box 1. At this time, the first baffle assembly 61 and the second baffle assembly 63 are squeezed out under pressure to realize the circulation of air pressure, and the outflowing hot air will dissipate into the interior of the preliminary heating equipment, reducing heat loss to ensure full utilization of heat in the melting process.
