Description

Technical Field

[0001] The invention relates to the technical field of laminating machines, and in particular to a metal sheet laminating machine with adjustable laminating pressure. Background Art

[0002] The metal sheet laminating machine is a machine that covers a thin film such as polyester film closely on a metal sheet such as a cadmium sheet. It is mainly used for the laminating process in the processing of metal film switches and other products. The traditional metal sheet laminating machine mainly includes a frame, a film roller, a motor, an upper pressure roller, a lower pressure roller, a transmission roller and a roller transmission belt. The motor drives the lower pressure roller to rotate, thereby driving the upper pressure roller and the transmission roller to rotate. The lower pressure roller and the transmission roller drive the roller transmission belt to rotate together. After the metal sheet is placed on the roller transmission belt, the roller transmission belt drives the metal sheet to move and pass between the upper pressure roller and the lower pressure roller together with the film. Under the joint action of the upper pressure roller and the lower pressure roller, the film is closely covered on the metal sheet to achieve the purpose of laminating.

[0003] For example, the Chinese utility model patent with application number: 201320306065.X, entitled "A Metal Sheet Laminating Machine with Adjustable Laminating Pressure", discloses a metal sheet laminating machine with adjustable laminating pressure, including a frame, a film roller, a motor, an upper pressure roller, a lower pressure roller, a transmission roller, a roller transmission belt, a pressure roller, an elastic column and a pressure mounting bracket, wherein the pressure roller is mounted on the lower end of the elastic column and can rotate freely, the pressure roller is placed above the upper pressure roller and is coaxial with the upper pressure roller, the middle section of the elastic column is elastic, the upper end of the elastic column is connected to the pressure mounting bracket, and the pressure mounting bracket is mounted on the frame. The utility model installs a pressure roller above the upper pressure roller so that the upper pressure roller can rotate while being pressurized, and due to the elastic force of the elastic column, the upper pressure roller is subjected to a downward elastic pressure and the size of the pressure can be adjusted, and the pressure makes the pressure between the upper pressure roller and the lower pressure roller greater (even if the pressure is too large), thereby achieving a better laminating effect.

[0004] The shortcomings of the prior art are: although the existing metal sheet laminating machine can adjust the laminating pressure, it often determines the required laminating pressure before processing the metal sheet, and then adjusts the downward pressure of the upper pressure roller on the film to an appropriate value. When laminating a large number of metal sheets of different thicknesses, it is impossible to adaptively adjust the laminating pressure according to the metal sheets of different thicknesses. It is difficult to ensure that the extrusion force of the upper pressure roller on the film and the metal sheet is always at a preset pressure value when laminating metal sheets of different thicknesses. Furthermore, when laminating metal sheets of different thicknesses, it is necessary to frequently stop the machine to adjust the extrusion force of the upper pressure roller, which is not conducive to efficient laminating operations on metal sheets of different thicknesses and affects the efficiency of metal sheet lamination.

[0031] In the solution further provided by the present invention, a lower pressure roller 111 is also provided in the plate conveyor belt 81. The lower pressure roller 111 is fixed on the machine body 1. The lower pressure roller 111 is arranged directly above the upper pressure roller 33 to increase the supporting force during lamination.

[0032] Working principle: when working, first pull the L-shaped unlocking plate 91 to move, and cooperate with the guide groove 93 set on the L-shaped unlocking plate 91 and the guide rod 94 set on the clamping rod 92 to drive the clamping rod 92 to move and separate from the support rod 32 on the support rod 32, and adjust the height of the upper pressure roller 33 by pulling the support rod 32 so that the metal plate and the film reach a suitable pressure value when passing. After the adjustment is completed, release the pulling force on the L-shaped unlocking plate 91, and the L-shaped unlocking plate 91 is reset under the action of spring six 97, and the clamping rod 92 is driven to reset again through the guide groove 93 and the guide rod 94 to clamp and fix the adjusted support rod 32.

When the limit plate 22 moves upward The inclined surface of the ratchet block 64 arranged inside it contacts the inclined surface of the ratchet plate 62, and moves up and is fixed under the action of the spring four 63, and when the limit plate 22 moves up, it will drive the movable plate 23 to move up synchronously through the connecting plate 31, and the movable plate 23 moves up and drives the connecting plate 31 to move up synchronously through the L-shaped connecting frame 4, and the connecting plate 31 moves up and drives the upper pressing roller 33 to move synchronously to a suitable position for laminating. When the metal plate after lamination moves away from the upper pressing roller 33, the next metal plate will move to the arc detection plate 24 under the action of the plate conveyor belt 81. If the metal plate is higher than the previous metal plate, it will contact the arc detection plate 24 again and continue to move up, and the limit plate 22, the connecting rod 21, the movable plate 23 and the L-shaped connecting frame 4 are driven to drive the connecting plate 31 to move to a suitable position for the next lamination; When the next metal plate is at the same height as the previous metal plate or is lower than the previous metal plate, at this time, after the next metal plate enters the arc detection plate 24, it does not fit with the arc detection plate 24 until the previous coating is pushed. When the inclined block 83 on the metal plate moving baffle 82 moves to the wedge block 72, it will push the wedge block 72 to move, and the wedge block 72 moves through the inclined slot 2 74 to push the unlocking rod 2 53 to move downward, and the unlocking rod 2 53 moves downward through the long plate 51 to push the unlocking rod 1 52 to move downward synchronously, and the unlocking rod 1 52 moves downward and separates from the ratchet plate 62. At this time, the ratchet plate 62 moves under the action of the spring three 61 and separates from the ratchet block 64. At this time, the arc detection plate 24 and the limit plate 22 will move downward under the action of the spring one 25 until they fit with the metal plate. After the arc detection plate 24 and the limit plate 22 move down, through the limit The cooperation of the positioning plate 22, connecting rod 21, movable plate 23 and L-shaped connecting frame 4 drives the connecting plate 31 to drive the upper pressure roller 33 to move down to a suitable position or remain in the original position without moving, waiting for the next metal plate to be coated, until the inclined block 83 that pushes the wedge block 72 to move continues to move and separates from the wedge block 72, the wedge block 72 moves and resets under the action of spring five 73, and the long plate 51 drives the unlocking rod one 52 to enter the inclined groove one 65 inside the ratchet plate 62 under the action of spring two 54, and pushes the ratchet plate 62 to move and engage with the ratchet block 64 in the moving limit plate 22 again, and the unlocking rod two 53 enters the inclined groove two 74 inside the reset wedge block 72, at this time the next metal plate enters from the arc detection plate 24 to the upper pressure roller 33 for coating and pressing.
