Description

Technical Field

[0001] The present invention relates to the technical field of air suction platforms, in particular to an air suction platform for a printer. Background Art

[0002] The suction platform needs to adjust its height to meet various processing requirements. Under the existing technology, the suction platform is equipped with hydraulic mechanisms at the four corners of the platform. The hydraulic mechanisms can push the platform up and down, but this driving method is relatively laborious and requires a hydraulic device with a large driving force to achieve the lifting of the platform. In the process of lifting the platform, the platform may tilt and offset due to the lack of coordinated drive between multiple hydraulic mechanisms. The printer also needs to protect key components to avoid collisions between components due to failure of the drive device. Summary of the Invention

[0003] In order to solve the above technical problems, the present invention provides a suction platform with a lifting function, which has a labor-saving lifting method, a stable lifting process, and can avoid tilting and offsetting during the lifting process.

[0006] In this solution, the driving module can drive the platform chassis to move. When the platform chassis slides along the first slide rail, the platform chassis drives the first slider to slide on the second slide rail. At this time, the height of the lifting connecting plate changes with the sliding of the first slider, and the lifting connecting plate drives the suction platform body to lift and lower. During the sliding of the first slider, the traction rod can give the suction platform body an upward supporting force to prevent the suction platform body from losing its supporting force. The buffer component can provide buffering protection to the platform chassis when the driving module fails to prevent the platform chassis from colliding.

[0007] Preferably, there are two first slide rails and they are symmetrically arranged front to back. One side of the traction frame is slidably connected to one of the first slide rails via a connecting mechanism. The connecting mechanism includes a second slider and a third connecting member.

The guide column is used to maintain the direction of the buffer to avoid the buffer effect being reduced due to the change of the direction of the buffer. At the same time, the guide column also limits the first connecting part so that the first connecting part can only move up and down along the guide column. The buffer is used to absorb vibrations in the vertical direction and reduce the transmission of vibrations. The linear drive module drives the traction frame to move. The movement of the traction frame can drive the platform base and the suction platform body to move synchronously.

The bolt limits the upper connecting plate so that the upper connecting plate can only slide up and down along the bolt. At the same time, the limiting nut at the top of the bolt can limit the upper connecting plate and the first connecting member connected to the upper connecting plate, thereby preventing the upper connecting plate and the first connecting member from being separated from the bolt, and also preventing the first connecting member from being separated from the guide column.

[0010] Preferably, the connecting mechanism also includes a first cylinder arranged horizontally, the limiting sliding module also includes a second cylinder arranged horizontally, the top of the second slider is provided with a first receiving groove to accommodate the bottom of the first cylinder, the third connecting member is provided with a second receiving groove corresponding to the position of the first receiving groove, the first cylinder is arranged in the second receiving groove and the lower portion extends out of the second receiving groove to contact the first receiving groove, a first limiting component is provided at the opening of the second receiving groove to prevent the first cylinder from disengaging from the second receiving groove, the first cylinder is used to lift the third connecting member so that there is a gap between the second slider and the third connecting member, the top of the fourth slider is provided with a third receiving groove to accommodate the bottom of the second cylinder, the upper connecting plate is provided with a fourth receiving groove corresponding to the position of the third receiving groove, the second cylinder is arranged in the fourth receiving groove and the lower portion extends out of the fourth receiving groove to contact the third receiving groove, the second limiting component is provided at the opening of the fourth receiving groove to prevent the second cylinder from disengaging from the fourth receiving groove, and the second cylinder is used to lift the upper connecting plate so that there is a gap between the fourth slider and the upper connecting plate. Traditional technology relies on the fitting of parts to provide support. After long-term operation, deformation occurs between parts, resulting in vibration when the machine is running due to deformation. Compared with traditional technology, the present invention uses two second cylinders to cooperate with the first cylinder to form a three-point support.

The lifting connecting plate 51 is arranged on the inner side of the first connecting plate 31 on the corresponding side.

[0037] When the driving module drives the platform chassis to move to the left on the first slide rail, the platform chassis drives the first slider to move to the left on the second slide rail, and the lifting connecting plate falls with the movement of the first slider. When the driving module drives the platform chassis to move to the right on the first slide rail, the platform chassis drives the first slider to move to the right on the second slide rail, and the lifting connecting plate rises with the movement of the first slider. During the lifting and lowering process of the lifting connecting plate, the traction rod can give the suction platform body an upward supporting force to avoid the suction platform body losing its supporting force and causing lifting failure.

[0038] When the suction platform is working, vibration will be generated, and the vibration will affect the operation of the printer. The vibration generated when the suction platform is working is transmitted to the shock-absorbing sliding mechanism and absorbed by the buffer part which is a butterfly spring. In order to prevent the vibration from causing the first connecting part to separate from the guide column and causing a decrease in the shock-absorbing effect, the shock-absorbing sliding mechanism is symmetrically provided with limit sliding modules on the left and right sides. The limit sliding module limits the upper connecting plate, the lower connecting plate, the first connecting part and the guide column through bolts and limit nuts.

[0039] When the suction platform is working, the linear drive module may lose control, resulting in collisions between components. In order to avoid collisions, a buffer assembly is provided between the platform chassis and the traction frame. The buffer cylinder in the buffer assembly is fixed to the traction frame, and the buffer column is fixed to the platform chassis. The buffer column extends into the buffer cylinder and squeezes the buffer spring to stop the movement of the platform chassis and avoid collisions.

[0040] In order to ensure that the lifting mechanism can operate smoothly, the lifting mechanism is arranged on the inner side of the first connecting plate on the corresponding side to avoid interference with the first slide rail.

[0041] After the suction platform has been working for a long time, the suction platform body may tilt slightly. In order to adjust the suction platform body to a horizontal state, an adjustment component is provided between the first slide rail and the platform base frame. By rotating the adjusting screw, the position of the adjusting block in the slide groove is changed, thereby driving the first slider to slide on the second slide rail, thereby changing the height of the single-side lifting connecting plate, changing the height of one side of the suction platform body, and finally restoring the suction platform body to a horizontal state.

[0042] Traditional technology relies on the fit between parts to provide support. After long-term operation, deformation occurs between parts, resulting in vibration when the machine is running due to deformation. Compared with traditional technology, the present invention uses two second cylinders and the first cylinder to cooperate with each other to form a three-point support. The three-point support solves the problem caused by the unevenness or deformation of the traction frame mounting surface during machine operation. After the three-point support is adopted, the traction frame mounting surface is not in direct contact with the slider, avoiding vibration caused by the flatness not meeting the standard due to the large size of the workpiece, and also avoiding vibration caused by the deformation of the traction frame mounting surface.
