DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 A lifting mechanical synchronization mechanism of a flip frame in this embodiment includes a flip frame assembly 1, and a lifting mechanism is arranged inside the flip frame assembly 1.

[0021] In this embodiment, the lifting mechanism includes a first linear guide 2 and a second linear guide 3 fixedly connected to the flip frame assembly 1, and the inner walls on the left and right sides of the flip frame assembly 1 are both transmission-connected with a balance chain 4. There are four first linear guides 2 and second linear guides 3, and the four first linear guides 2 and second linear guides 3 are symmetrically distributed, which is convenient for lifting and adjusting. The first linear guide 2, the second linear guide 3 and the balance chain 4 are used to achieve single-sided front and back and left and right lifting synchronization. The structure is simpler and more reliable, which is convenient for clamping and flipping the corrugated cardboard. The inner walls on the left and right sides of the flip frame assembly 1 are both fixedly connected with a conveying pipe 5, and the outside of the conveying pipe 5 is fixedly connected with two air intake branch pipes 6.

[0022] Among them, a reflux valve 501 is fixedly connected to the inside of the delivery pipe 5, and the reflux valve 501 is located at the top of the intake branch pipe 6. The other end of the delivery pipe 5 is fixedly connected to the gas tank, and the gas tank is filled with high-pressure gas. The gas tank control valve and the reflux valve 501 are opened, and the high-pressure gas inside the gas tank enters the intake branch pipe 6 through the delivery pipe 5. The reflux valve 501 is closed to reduce the reflux of the high-pressure gas and facilitate the lifting and lowering adjustment. The other end of the intake branch pipe 6 is fixedly connected to the cylinder 7 fixedly connected to the flip frame assembly 1, and the output end of the cylinder 7 is fixedly connected to the connecting seat 702. The connecting seat 702 is circular, and a threaded hole is opened inside the connecting seat 702. The user connects it to the clamping plate through the mutual cooperation of the threaded hole and the fixing screw, which is convenient for the connection between the output end of the cylinder 7 and the clamping plate. The cylinder 7 is extended and retracted, driving the clamping plate to move up and down to clamp and limit the corrugated cardboard.

[0023] Among them, a flow port 701 is opened on the opposite side of the two cylinders 7, and the air intake branch pipe 6 is connected with the cylinder 7 through the flow port 701. The high-pressure gas entering the air intake branch pipe 6 enters the cylinder 7 through the flow port 701. The internal components of the cylinder 7 are pressurized, causing the cylinder 7 to extend, driving the clamping plate or frame to slide linearly inside the first linear guide rail 2 and the second linear guide rail 3, clamping the corrugated cardboard for convenient lifting and lowering adjustment, and facilitating the clamping and limiting of the corrugated cardboard. The inner walls of the left and right sides of the flip frame assembly 1 are fixedly connected to small air pumps 9, and the input end of the small air pump 9 is fixedly connected to the first reflux pipe 8 fixedly connected to the delivery pipe 5, and the output end of the small air pump 9 is fixedly connected to the first return pipe 8 fixedly connected to the delivery pipe 5. A second reflux pipe 10 and a connecting hole are provided on one side of the delivery pipe 5. The first reflux pipe 8 is connected to the delivery pipe 5 through the connecting hole. The first reflux pipe 8 is located on the top of the reflux valve 501. The second reflux pipe 10 is fixedly connected to the gas tank. When the processing of the corrugated cardboard is completed, the reflux valve 501 is opened, and the small air pump 9 is powered on. The high-pressure gas inside the cylinder 7 is extracted through the first reflux pipe 8, the delivery pipe 5 and the intake branch pipe 6, and the high-pressure gas is re-transported to the gas tank through the second reflux pipe 10. The cylinder 7 contracts and drives the clamping plate or frame to move upward, releasing the clamping of the corrugated cardboard, and performing lifting and lowering adjustments, thereby forming an air circulation, facilitating lifting and lowering adjustments, reducing the use cost, and saving resources.

[0024] The beneficial effects of the above embodiments are:

[0025] By setting up a lifting mechanism, the first linear guide 2, the second linear guide 3 and the balance chain 4 cooperate with each other, so as to facilitate the left and right synchronous lifting and adjustment. After being driven by the cylinder 7, it is convenient to clamp the corrugated cardboard and flip the corrugated cardboard, which solves the problem that it is inconvenient to perform left and right synchronous lifting and adjustment when the corrugated cardboard is pressed, which affects the efficiency of the lifting and adjustment and is inconvenient to clamp and flip the corrugated cardboard.

[0026] The working principle of the above embodiment is:

[0027] The lifting mechanical synchronization mechanism of the flip frame is such that during the process of the flip frame flipping the corrugated cardboard, the gas tank control valve and the reflux valve 501 are opened, and the high-pressure gas inside the gas tank enters the interior of the air intake branch pipe 6 through the delivery pipe 5, and the high-pressure gas entering the interior of the air intake branch pipe 6 enters the interior of the cylinder 7 through the flow port 701. The internal components of the cylinder 7 are pressurized, causing the cylinder 7 to extend, pushing the clamping plate or the frame to move, so that the clamping plate or the frame slides linearly inside the first linear guide rail 2 and the second linear guide rail 3 to clamp the corrugated cardboard. When the processing of the corrugated cardboard is completed, the reflux valve 501 is opened, and the small air pump 9 is energized to extract the high-pressure gas inside the cylinder 7 through the first reflux pipe 8, the delivery pipe 5 and the air intake branch pipe 6, and re-deliver the high-pressure gas to the gas tank through the second reflux pipe 10, thereby forming an air circulation, thereby achieving the purpose of facilitating the left and right synchronous lifting and lowering adjustment and facilitating the clamping of the corrugated cardboard.
