[0033] ​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.

Figure 1 An enlarged structural diagram at point A. This invention provides a continuous hot press, comprising an upper frame 6, a lower frame 7, a rotating pressure roller assembly 1, and a pressure plate mechanism 2; the pressure plate mechanism 2 is disposed in the middle portion of the rotating pressure roller assembly 1; the rotating pressure roller assembly includes a first sub-rotating pressure roller assembly 11 disposed on the upper frame 6 and a second sub-rotating pressure roller assembly 12 disposed on the lower frame 7; the first sub-rotating pressure roller assembly 11 and the second sub-rotating pressure roller assembly 12 are used to transport the workpiece to be processed to the pressure plate mechanism 2.

[0035] Specifically, the first sub-rotating pressure roller assembly 11 and the second sub-rotating pressure roller assembly 12 are connected by an intermediate connecting frame. Two intermediate connecting frames are provided at the front of the continuous hot press, and two intermediate connecting frames are provided at the rear of the continuous hot press to ensure a stable connection between the first sub-rotating pressure roller assembly 11 and the second sub-rotating pressure roller assembly 12.

[0036] Furthermore, the pressure plate mechanism 2 includes a first pressure plate 21 and a second pressure plate 22. The first pressure plate 21 is disposed above the second pressure plate 22. A plurality of first adjustment mechanisms 4 are provided between the first pressure plate 21 and the second pressure plate 22. The two pressure plates are connected based on the first adjustment mechanisms 4, so that a preset gap is provided between the first pressure plate 21 and the second pressure plate 22. The workpiece to be processed passes through the preset gap under the drive of the rotating pressure roller assembly 1, and completes the lamination process under the action of the first pressure plate 21 and the second pressure plate 22. The first pressure plate 21 is used for hot pressing the workpiece to be processed. The size of the first pressure plate 21 can completely cover the workpiece to be processed, so as to uniformly hot press the workpiece to be processed. The first pressure plate 21 and the second pressure plate 22 are rectangular structures of the same size, so that the workpiece is hot pressed evenly.

[0037] A plurality of first adjusting mechanisms 4 are arranged between the two outer side walls of the first pressing plate 21 and the two outer side walls of the second pressing plate 22. The first adjusting mechanism 4 comprises an upper matching block 41 arranged on the outer side wall of the first pressing plate 21, a lower matching block 42 arranged on the second pressing plate 22, and a movable matching block 43 arranged between the upper matching block 41 and the lower matching block 42. The thickness of the movable matching block 43 can be replaced and adjusted according to actual processing needs. The upper matching block 41 and the lower matching block 42 are connected by a latch. When the first pressing plate 21 is pressed down, the distance between the upper matching block 41 and the lower matching block 42 decreases until the upper matching block 41 and the lower matching block 42 are in contact with the movable matching block 43. By replacing the movable matching block 43 with different thicknesses, the distance between the first pressing plate 21 and the second pressing plate 22 can be adjusted to the micron level, improving the pressing accuracy of the connecting hot press.

[0038] Specifically, the working principle of the first adjusting mechanism 4: the preset gap between the first pressing plate 21 and the second pressing plate 22 may not be accurate enough, which may cause incomplete hot pressing of the workpiece to be processed. The first adjusting mechanism 4 can adjust the preset gap between the first pressing plate 21 and the second pressing plate 22 to improve the accuracy of the preset gap between the first pressing plate 21 and the second pressing plate 22. Specifically, the working principle of the pressing plate mechanism 2 is as follows: the first sub-rotating pressing roller assembly 11 and the second sub-rotating pressing roller assembly 12 transport the workpiece to be processed to the pressing plate mechanism 2. The first pressing plate 21 is lowered to hot-press the workpiece to be processed. The multi-layer sheet material in the workpiece to be processed is pressed and combined into a composite workpiece through hot pressing. After the first pressing plate 21 completes the hot pressing operation, the first pressing plate 21 rises to the initial position. The first sub-rotating pressing roller assembly 11 and the second sub-rotating pressing roller assembly 12 transport the workpiece after hot pressing out of the material.

[0039] Further, the pressing plate mechanism 2 is provided with a heating device. The heating device comprises an oil temperature machine arranged outside the pressing plate mechanism 2. The oil temperature machine has heat-conducting oil inside. The oil temperature machine heats the heat-conducting oil inside. The first pressing plate 21 and the second pressing plate 22 are internally provided with pipelines for the flow of the heat-conducting oil. The inlet of the pipeline is in communication with the oil outlet of the oil temperature machine, and the outlet of the pipeline is in communication with the oil return port of the oil temperature machine. The oil temperature machine drives the heated heat-conducting oil to the pipeline inside the first pressing plate 21 and the second pressing plate 22. After the heat-conducting oil flows inside the first pressing plate 21 and the second pressing plate 22, it enters the oil temperature machine for heating. Through the circulation of the heat-conducting oil between the oil temperature machine and the first pressing plate 21 and the second pressing plate 22, the overall temperature of the first pressing plate 21 and the second pressing plate 22 is maintained.

[0040] Specifically, when the pressing plate mechanism 2 is hot-pressing the workpiece to be processed, the first pressing plate 21 and the second pressing plate 22 are kept at a certain temperature, so that the workpiece to be processed is heated while being hot-pressed, so that the multi-layer material of the workpiece to be processed can be tightly connected under the action of hot-pressing, thereby improving the effect of laminated forming.

[0041] Further, the first sub-rotating pressing roller assembly 11 comprises a first steel belt 111, a first tensioning mechanism 116, a first driving roller 112 and a first driven roller 113; the first driving roller 112 is arranged at one end inside the first steel belt 111, and is used to provide power to drive the first steel belt 111; the first driven roller 113 is arranged at one end inside the first steel belt 111; the first driving roller 112 is in sliding connection with the first steel belt 111, and the first driven roller 113 is in rotating connection with the first steel belt 111. The first tensioning mechanism 116 is drivingly connected with the first driven roller 113, and when the continuous hot-pressing machine is performing hot-pressing operation, the first tensioning mechanism 116 is used to drive the first driven roller 113 to move towards the pressing plate mechanism 2, and when the continuous hot-pressing machine is performing conveying operation, the first tensioning mechanism 116 is used to drive the first driven roller 113 to move away from the pressing plate mechanism 2.

[0042] Further, the first tensioning mechanism 116 can be driven by a hydraulic cylinder or an electric cylinder to realize driving movement of the first driven roller 113.

[0043] Specifically, the working principle of the first tensioning mechanism 116 is as follows: when the workpiece to be processed is conveyed into the pressing plate mechanism 2, the first tensioning mechanism 116 drives the first driven roller 113 to move towards the pressing plate mechanism 2, so as to relax the first steel belt 111, so that the first steel belt 111 has a certain activity area, and the first pressing plate 21 drives the first steel belt 111 to move downwards, so as to improve the tensioning degree of the first steel belt 111, and the first steel belt 111 can be kept within a suitable tensioning degree during hot-pressing, thereby reducing the damage risk of the first steel belt 111; after the pressing plate mechanism 2 completes hot-pressing, the first pressing plate 21 rises to the initial position, the first tensioning mechanism 116 drives the first driven roller 113 to move away from the pressing plate mechanism 2, so as to improve the tensioning degree of the first steel belt 111, so that the first steel belt 111 can drive the workpiece to be processed to be conveyed out.

[0044] Specifically, one end outside of the hole of the first driving roller 112 is provided with a first speed reducer 110, one side of the first speed reducer 110 is provided with a first motor 114, the first motor 114 is drivingly connected with the first speed reducer 110, and the first speed reducer 110 is used for adjusting the rotating speed of the first driving roller 112 and increasing the output torque of the first motor 114, so as to ensure that the first sub-rotating pressure roller assembly 11 can meet the driving demand of the workpiece transmission.

[0045] Specifically, the working principle of the first speed reducer 110 and the first motor 114 is that the first motor 114 is drivingly connected with the first driving roller 112 based on the first speed reducer 110, the first driving roller 112 is rotated, the first speed reducer 110 provides resistance to the first driving roller 112, the rotating speed of the first driving roller 112 is adjusted, and the output torque of the first motor 114 is increased. Further, the second sub-rotating pressure roller assembly 12 includes a second steel belt 121, the second sub-rotating pressure roller assembly 12 further includes a second driving roller 122 and a second driven roller 123, the second driving roller 122 is arranged at one end inside the second steel belt 121, the second driven roller 123 is arranged at one end inside the second steel belt 121, the second driving roller 122 is slidingly connected with the second steel belt 121, and the second driven roller 123 is slidingly connected with the second steel belt 121. The second driving roller 122 is used for providing power to drive the second steel belt 121, the second driven roller 123 is arranged at one end inside the second steel belt 121, the second driving roller 122 is slidingly connected with the second steel belt 121, and the second driven roller 123 is rotationally connected with the second steel belt 121.

[0046] Specifically, one end outside of the hole of the second driving roller 122 is provided with a second speed reducer 120, one side of the second speed reducer 120 is provided with a second motor 124, the second motor 124 is drivingly connected with the second speed reducer 120, and the second speed reducer 120 is used for adjusting the rotating speed of the second driving roller 122 and increasing the output torque of the second motor 124, so as to ensure that the second sub-rotating pressure roller assembly 12 can meet the driving demand of the workpiece transmission.

[0047] Specifically, the working principle of the second speed reducer 120 and the second motor 124 is that the second motor 124 is drivingly connected with the second driving roller 122 based on the second speed reducer 120, the second driving roller 122 is rotated, the second speed reducer 120 provides resistance to the second driving roller 122, the rotating speed of the second driving roller 122 is adjusted, and the output torque of the second motor 124 is increased.

[0048] Further, the first steel belt 111 moves in the opposite direction of the second steel belt 121, the first pressing plate 21 is arranged above the bottom of the first steel belt 111, and the second pressing plate 22 is arranged below the top of the second steel belt 121.

[0049] Specifically, the working principle of the first steel belt 111 and the second steel belt 121 is that the workpiece to be processed is placed on one end above the second steel belt 121, and the moving direction above the second steel belt 121 is towards the pressing plate mechanism 2. Since the first steel belt 111 moves in the opposite direction of the second steel belt 121, the moving direction below the first steel belt 111 is towards the pressing plate mechanism 2. The workpiece to be processed fixed below the first steel belt 111 and above the second steel belt 121 moves in the same direction to be transported to the inside of the pressing plate mechanism 2. After the workpiece to be processed is hot-pressed by the pressing plate mechanism 2, the workpiece to be processed fixed below the first steel belt 111 and above the second steel belt 121 moves in the same direction to the outside of the pressing plate mechanism 2.

The second tensioning mechanism enables the second driven roller 123 to tension the second steel belt 121, thereby controlling the movement state of the second steel belt 121.

[0051] The second tensioning mechanism can drive the second driven roller 123 to move through a hydraulic cylinder or an electric cylinder.

[0052] Specifically, the working principle of the second tensioning mechanism is that when the tension of the second steel belt 121 is detected to decrease, the second tensioning mechanism can drive the second driven roller 123 to move away from the pressing plate mechanism 2, so that the second steel belt 121 can maintain a suitable tension degree to meet the requirements of workpiece transportation.
