Description

Technical Field

[0001] This invention relates to the field of steel strip pre-compression machine technology, specifically to a steel strip pre-compression machine. Background Technology

[0002] In the production of fiberboard and particleboard, the material pad needs to be pre-compressed using a continuously operating pre-press. The purpose of pre-compression is: 1. To compact the material pad, giving it a certain density or interlocking force, preventing it from collapsing or breaking during transport; 2. To reduce the thickness of the material pad, thereby reducing the distance between the upper and lower hot press plates, thus shortening the press closing time, i.e., shortening the hot pressing cycle and improving production efficiency; 3. To expel air from the material pad, preventing a large amount of air from rushing out and damaging the material pad during hot pressing. Currently, the double-belt continuous pre-compression process and equipment have been widely accepted and applied in the engineered wood products industry.

[0003] However, during the operation of the pre-press, the upper steel belt has through holes on its surface for venting. As a result, the upper steel belt will be severely worn after traveling a certain distance, and the machine must be stopped to replace the steel belt. However, the steel belt used in the pre-press is a whole piece, and replacing it is very laborious. It is necessary to dismantle the frame and other parts before replacement, and the replacement time can be as long as 0.5-1 day, which affects production. Therefore, we need a steel belt pre-press that can replace the steel belt without long downtime. Summary of the Invention

[0004] This invention proposes a steel belt pre-compression machine, which solves the problem in related technologies that the upper steel belt is prone to wear and requires machine downtime for replacement.

[0005] The technical solution of the present invention is as follows:

[0006] A steel strip preload press includes a frame and a tilting frame rotatably mounted on the frame. It also includes a first upper pressure roller assembly, a lower pressure roller assembly, and a second upper pressure roller assembly mounted on the tilting frame. The first upper pressure roller assembly, the lower pressure roller assembly, and the second upper pressure roller assembly are sequentially distributed vertically. The first upper pressure roller assembly and the second upper pressure roller assembly, together with the lower pressure roller assembly, form working spaces.

[0007] A sliding frame is slidably mounted on the machine frame, and the sliding direction of the sliding frame is perpendicular to the plane containing the rotation direction of the tilting frame.

[0009] As a further technical solution, the first upper pressure roller assembly includes,

[0010] There are two first driving upper pressure rollers, which are arranged on the tilting frame and are located on the same horizontal plane.

[0011] A first upper pressure steel strip, which is sleeved on two first drive upper pressure rollers, and a second upper pressure roller assembly including...

[0012] There are two second drive upper pressure rollers, which are mounted on the tilting frame and are located on the same horizontal plane.

[0013] The second upper pressure steel strip is sleeved on the two second drive upper pressure rollers, and the first upper pressure steel strip and the second upper pressure steel strip are located on both sides of the lower pressure roller assembly in the vertical direction.

[0014] As a further technical solution, both the first upper pressing steel strip and the second upper pressing steel strip have a plurality of vent holes, and the plurality of vent holes are evenly distributed on the first upper pressing steel strip and the second upper pressing steel strip.

[0015] As a further technical solution, the mesh belt assembly includes,

[0016] The conveyor belt has several support rollers, all of which are mounted on the sliding frame.

[0017] A ventilation mesh belt is sleeved on a plurality of mesh belt support rollers, and the sliding frame moves to drive the ventilation mesh belt into or out of the working space.

[0018] As a further technical solution, the conveyor belt assembly also includes,

[0019] An adjusting roller is movably mounted on the sliding frame, and a ventilation mesh belt is sleeved on the adjusting roller and the mesh belt support roller.

[0020] A linear drive device is mounted on the sliding frame, and the telescopic end of the linear drive device is connected to the adjusting roller. The linear drive device is used to drive the adjusting roller to move.

[0021] As a further technical solution, the lower pressure roller assembly includes,

[0022] There are two driving lower pressure rollers, both rotatably mounted on the tilting frame and located on the same horizontal plane. Correspondingly, the first and second driving upper pressure rollers are located in the same vertical direction as the driving lower pressure rollers.

[0023] The lower pressure steel strip is sleeved on the two driving lower pressure rollers, and the lower pressure steel strip, together with the first upper pressure steel strip and the second upper pressure steel strip, respectively form a working space.

[0024] As a further technical solution, it also includes,

[0025] A first guide roller is rotatably mounted on the tilting frame, and several first guide rollers are distributed along the conveying direction.

[0026] The second guide roller is rotatably mounted on the tilting frame. Several second guide rollers are distributed along the conveying direction. Adjacent first guide rollers and second guide rollers are distributed vertically. Both the first guide roller and the second guide roller are located within the working space.

[0027] As a further technical solution, a guide rail is also included, which is mounted on the frame, and the sliding frame is slidably mounted on the guide rail.

[0028] As a further technical solution, a vacuum nozzle is also included, which is disposed on the flipping frame, with the working ends of the plurality of vacuum nozzles pointing towards the workspace.

[0029] As a further technical solution, a drive motor is also included, which is mounted on the frame and its output end is connected to the tilting frame.

[0030] The working principle and beneficial effects of this invention are as follows:

[0031] In order to solve the above-mentioned technical problems, this invention proposes a steel belt pre-compression machine, including a frame and a tilting frame rotatably mounted on the frame. It also includes a first upper pressure roller assembly, a lower pressure roller assembly, and a second upper pressure roller assembly mounted on the tilting frame. The first and second upper pressure roller assemblies and the lower pressure roller assembly respectively form a working space. Furthermore, it includes a sliding frame and a mesh belt assembly. The sliding frame is mounted on the frame, and its sliding direction is perpendicular to the plane containing its rotation direction. The mesh belt assembly is mounted on the sliding frame and moves with the sliding frame. The sliding of the sliding frame drives the mesh belt assembly into or out of the working space.

[0032] During operation, the first or second upper pressure roller assembly works in conjunction with the lower pressure roller assembly to perform pressing. When the first upper pressure steel strip in the first upper pressure roller assembly or the second upper pressure steel strip in the second upper pressure roller assembly is damaged, the sliding component is first driven to slide, thereby moving the sliding mesh belt assembly to the side of the frame. At this time, the tilting frame tilts, exchanging the positions of the first and second upper pressure roller assemblies. The tilted upper pressure roller assembly then works in conjunction with the lower pressure roller assembly to continue pressing, avoiding the need to stop the machine to replace the steel strip. When the upper and lower pressure roller assemblies work together, the venting mesh belt in the mesh belt assembly needs to be located between the two steel strips to facilitate the discharge of gas from the material. When it is necessary to replace the steel strip, the venting mesh belt needs to be sent out before the tilting can be performed. Therefore, the tilting frame needs to be moved to tilt the machine and replace the first and second upper pressure roller assemblies.

[0033] Beneficial effects: By setting up a flipping frame, the first and second upper pressure roller assemblies can be replaced, allowing work to continue without stopping the machine to replace the steel belt. The sliding frame moves, driving the mesh belt assembly to move, without obstructing the flipping frame. After the first and second upper pressure roller assemblies are replaced, the sliding frame moves, driving the mesh belt assembly to return to its original position, allowing work to continue, thereby improving processing efficiency. The steel belt can be replaced after processing is completed. Attached Figure Description

[0043] Example 1

[0044] Reference Figures 1-3 As a first embodiment of the present invention, a steel belt pre-compression machine is proposed, including a frame 1 and a tilting frame 2 rotatably mounted on the frame 1. It also includes a first upper pressure roller assembly 3, a lower pressure roller assembly 4, and a second upper pressure roller assembly 5 mounted on the tilting frame 2. The first upper pressure roller assembly 3, the lower pressure roller assembly 4, and the second upper pressure roller assembly 5 are sequentially distributed vertically, and the first upper pressure roller assembly 3 and the second upper pressure roller assembly 5, together with the lower pressure roller assembly 4, form working spaces. Furthermore, it includes a sliding frame 6, which is slidably mounted on the frame 1. The sliding direction of the sliding frame 6 is perpendicular to the plane containing the rotation direction of the tilting frame 2. A mesh belt assembly 12 is mounted on the sliding frame 6 and moves with the sliding frame 6. The sliding of the sliding frame 6 drives the mesh belt assembly 12 into or out of the working space.

[0045] In this embodiment, to solve the above-mentioned technical problems, a steel strip pre-pressing machine is proposed, including a frame 1 and a tilting frame 2 rotatably mounted on the frame 1. It also includes a first upper pressure roller assembly 3, a lower pressure roller assembly 4, and a second upper pressure roller assembly 5 mounted on the tilting frame 2. The first upper pressure roller assembly 3 and the second upper pressure roller assembly 5, together with the lower pressure roller assembly 4, form a working space. Furthermore, it includes a sliding frame 6 and a mesh belt assembly 12. The sliding frame 6 is mounted on the frame 1, and the sliding direction of the sliding frame 6 is perpendicular to the plane containing the rotation direction of the sliding frame 6. The mesh belt assembly 12 is mounted on the sliding frame 6 and moves with the sliding frame 6. The sliding of the sliding frame 6 drives the mesh belt assembly 12 into or out of the working space. During operation, the first upper pressure roller assembly 3 or the second upper pressure roller assembly 5 cooperates with the lower pressure roller assembly 4 to perform pressing. When the first upper pressure roller assembly 3 presses the steel strip... When the second upper pressure steel belt 10 in the second upper pressure roller assembly 5 is damaged, the sliding component is first driven to slide, thereby moving the sliding mesh belt assembly 12 to the side of the frame 1. At this time, the flipping frame 2 flips, so that the positions of the first upper pressure roller assembly 3 and the second upper pressure roller assembly 5 are exchanged, so that the flipped upper pressure roller assembly can work with the lower pressure roller assembly 4 to continue the pressing work, avoiding the problem of stopping the machine to replace the steel belt. When the upper pressure roller assembly and the lower pressure roller assembly 4 work together, the ventilation mesh belt 14 in the mesh belt assembly 12 needs to be located between the two steel belts to facilitate the discharge of gas in the material. When it is necessary to replace the steel belt, the ventilation mesh belt 14 needs to be sent out before it can be flipped. Therefore, the flipping frame 2 needs to be moved to flip it, so as to replace the first upper pressure roller assembly 3 and the second upper pressure roller assembly 5. By setting up the flipping frame 2, the first upper pressure roller assembly 3 and the second upper pressure roller assembly 5 can be replaced, so that the work can continue without stopping the machine to replace the steel belt. The sliding frame 6 moves to drive the mesh belt assembly 12 to move, which does not obstruct the flipping frame 2 from flipping. After the first upper pressure roller assembly 3 and the second upper pressure roller assembly 5 are replaced, the sliding frame 6 moves to drive the mesh belt assembly 12 to move back to its original position, so that the work can continue, thereby improving the processing efficiency. The steel belt can be replaced after the processing is completed.

[0046] Example 2

[0047] Compared to Embodiment 1, the first upper pressure roller assembly 3 further includes two first driving upper pressure rollers 7, which are disposed on the flipping frame 2 and located on the same horizontal plane. The first upper pressure steel strip 8 is sleeved on the two first driving upper pressure rollers 7. The second upper pressure roller assembly 5 includes two second driving upper pressure rollers 9, which are disposed on the flipping frame 2 and located on the same horizontal plane. The second upper pressure steel strip 10 is sleeved on the two second driving upper pressure rollers 9. The first upper pressure steel strip 8 and the second upper pressure steel strip 10 are located on opposite sides of the lower pressure roller assembly 4 in the vertical direction. Both the first upper pressure steel strip 8 and the second upper pressure steel strip 10 have a plurality of ventilation holes 11, which are evenly distributed on the first upper pressure steel strip 8 and the second upper pressure steel strip 10.

[0048] In this embodiment, the first upper pressure roller assembly 3 drives the first upper pressure steel belt 8 to move through the first driving upper pressure roller 7, thereby enabling the first upper pressure steel belt 8 to cooperate with the lower pressure steel belt 19 to press the material. The second upper pressure roller assembly 5 works on the same principle as the first upper pressure roller assembly 3. Ventilation holes 11 are provided on the first upper pressure steel belt 8 and the second upper pressure steel belt 10 to allow gas in the material to be discharged through the ventilation holes 11 during material pressing. This ensures the need for air venting on the surface of the material pad while maximizing the preservation of the structural strength and fatigue resistance of the steel belt. Because the first upper pressure steel belt 8 and the second upper pressure steel belt 10 have ventilation holes 11, they are more prone to damage than the lower pressure steel belt 19.

[0049] Example 3

[0050] Compared to Embodiment 2, the mesh belt assembly 12 further includes mesh belt support rollers 13, of which there are several, all of which are disposed on the sliding frame 6. A ventilated mesh belt 14 is fitted onto the several mesh belt support rollers 13. The sliding frame 6 is movable to drive the ventilated mesh belt 14 into or out of the working space. The mesh belt assembly 12 also includes an adjusting roller 15, which is movably disposed on the sliding frame 6. The ventilated mesh belt 14 is fitted onto the adjusting roller 15 and the mesh belt support rollers 13. A linear drive device 16 is disposed on the sliding frame 6, and the telescopic end of the linear drive device 16 is connected to the adjusting roller 15. The linear drive device 16 is used to drive the adjusting roller 15 to move.

[0051] In this embodiment, during operation, the support roller in the mesh belt assembly 12 drives the ventilation mesh belt 14 to move, thereby assembling with the first upper pressure steel belt 8 and the lower pressure steel belt 19. The adjusting roller 15 can move on the sliding frame 6 to tension the ventilation mesh belt 14, thereby improving the working effect of the mesh belt. The linear drive device 16 drives the adjusting roller 15 to move linearly, thereby tensioning the ventilation mesh belt 14.

[0052] Example 4

[0053] Compared to Embodiment 3, the lower pressure roller assembly 4 further includes,

[0054] There are two driving lower pressure rollers 17, both of which are rotatably mounted on the flipping frame 2. The two driving lower pressure rollers 17 are located on the same horizontal plane, and correspondingly, the first driving upper pressure roller 7 and the second driving upper pressure roller 9 are located in the same vertical direction as the driving lower pressure rollers 17.

[0055] A downward pressing steel strip 19 is sleeved on two driving downward pressing rollers 17. The downward pressing steel strip 19, the first upward pressing steel strip 8, and the second upward pressing steel strip 10 respectively form a working space. It also includes a first guide roller 20, which is rotatably mounted on the tilting frame 2. A plurality of first guide rollers 20 are distributed along the conveying direction. A second guide roller 21 is rotatably mounted on the tilting frame 2. A plurality of second guide rollers 21 are distributed along the conveying direction. Adjacent first guide rollers 20 and second guide rollers 21 are distributed vertically. Both the first guide roller 20 and the second guide roller 21 are located within the working space.

[0056] In this embodiment, the driving roller 17 drives the lower pressing steel belt 19 to move. The lower pressing steel belt 19 cooperates with the first upper pressing steel belt 8 or the second upper pressing steel belt 10 to press the material. The first guide roller 20 and the second guide roller 21 can keep the material movement linear, which is more conducive to processing.

[0057] Example 5

[0058] Compared to embodiment 4, this further includes a guide rail 22, which is mounted on the frame 1, and the sliding frame 6 is slidably mounted on the guide rail 22. It also includes suction nozzles 23, which are mounted on the tilting frame 2, with the working ends of several suction nozzles pointing towards the workspace. Finally, it includes a drive motor 24, which is mounted on the frame 1, and its output end is connected to the tilting frame 2.

[0059] In this embodiment, the guide rail 22 makes the sliding frame 6 move more smoothly, the dust suction nozzle 23 is used to absorb the waste and dust discharged during the pressing process in the material, and the drive motor drives the flipping frame 2 to flip, thereby realizing the flipping rotation, making the work more convenient.

[0060] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it.
