Description

Technical Field

[0001] This invention relates to the field of printing technology, specifically a novel paper stacking mechanism. Background Technology

[0002] With increasingly higher requirements for printing quality, there are also higher requirements for the surface smoothness of paper. However, the high-speed paper slitting currently used damages the surface smoothness of paper when the paper is overlapped.

[0003] Existing devices such as Figure 1 As shown, the high-speed belt drive shaft 4 drives the high-speed conveyor belt 1. Paper sheets 2 on the high-speed belt travel at high speed on the high-speed conveyor belt 1 individually, with the high-speed belt pressure roller 3 pressing down on the paper sheets 2 as they move. The high-speed belt drive shaft 4 and the low-speed belt drive shaft 6 have a height difference to allow the papers to overlap. When the paper sheets 2 on the high-speed belt reach the low-speed belt deceleration pressure roller 9, they are rapidly decelerated and fall onto the low-speed conveyor belt 7. They then continue to travel at the speed of the low-speed conveyor belt 7, and the suction of the paperboard 5 pulls down the tail of the paper sheets 2 on the high-speed belt, allowing the second sheet of paper sheets 2 to pass through. This process causes the papers to overlap and move together.

[0004] Disadvantages of this overlapping mechanism: If the surface finish of the paper is required to be high, when the paper is running at high speed, the high-speed collision is decelerated by the low-speed belt deceleration pressure roller 9 to overlap, which will cause the paper surface to be scratched at the collision position, thereby damaging the surface finish of the paper.

[0005] To address this issue, patent publication number CN202110490337.5 discloses a paper suction deceleration and stacking mechanism. This device uses negative pressure adsorption in conjunction with a deceleration belt to slow down the paper. However, the problem of paper wear still exists. Based on this, a new type of paper stacking mechanism is now provided. Summary of the Invention

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0023] Embodiment 1

[0024] Please refer to Figure 1 In the embodiments of the present application, a novel paper folding mechanism includes a high-speed conveying belt 4 for conveying paper on high-speed belt 5 and a low-speed conveying belt 9 for conveying low-speed belt paper 8. The low-speed conveying belt 9 and the high-speed conveying belt 4 are provided with a high-speed conveying small belt 6 for assisting the transfer of the paper on high-speed belt 5. The surfaces of the high-speed conveying small belt 6, the low-speed conveying belt 9 and the high-speed conveying belt 4 are all distributed with air holes. The high-speed small belt air pipe 7 is arranged on the high-speed conveying small belt 6 for adsorbing and dropping the paper on high-speed belt 5. The low-speed vacuum suction device 10 is arranged on the low-speed conveying belt 9 for generating adsorption force on the low-speed belt paper 8. The air inlet of the high-speed small belt air pipe 7 is connected with the buffer box through the air pipe 3. The two air inlets of the buffer box are connected with the vacuum suction reversing device 1 and the air blowing reversing device 2.

[0025] When working, the vacuum suction reversing device reverses the suction air pressure through the air pipe to the air pipe on the high-speed small belt, at this time the air pipe on the high-speed small belt is the vacuum suction air pressure. When the paper on the high-speed belt is transported to the high-speed conveying small belt by the high-speed conveying belt, the vacuum suction reversing device reverses the suction air pressure through the air pipe to the air pipe on the high-speed small belt to adsorb the paper on the high-speed conveying small belt, at this time the paper is mainly transported by the high-speed conveying small belt. The linear speed of the low-speed conveying belt is consistent with the linear speed of the high-speed conveying small belt. When the paper is transported to a position by the high-speed conveying small belt, the vacuum suction reversing device and the air blowing reversing device reverse the power to quickly change the suction air pressure in the air pipe and the air pipe on the high-speed small belt into blowing air pressure, separate the paper on the high-speed belt from the high-speed conveying small belt, at this time the paper on the high-speed belt falls on the low-speed conveying belt. At the same time, the linear speed of the low-speed conveying belt is quickly reduced a little, so that the paper on the high-speed belt can overlap on the paper on the low-speed belt. At this time, the paper on the high-speed belt has fallen on the low-speed conveying belt and is adsorbed on the low-speed conveying belt by the vacuum suction of the low-speed vacuum suction device, so that the paper on the high-speed belt can not be skewed when overlapping on the paper on the low-speed belt, thereby being transported by the low-speed conveying belt. In order to reduce the speed of the paper, the paper does not need to be slowed down by the traditional way of using a pressure roller to slow down and keep from skewing, thereby ensuring that the printing surface of the paper is not scratched, has no roller shadow, and has no scratches that affect the printing quality. The vacuum suction reversing device and the air blowing reversing device change once, and then the vacuum suction reversing device reverses the suction air pressure through the air pipe to the air pipe on the high-speed small belt, at this time the air pipe on the high-speed small belt is the vacuum suction air pressure. This is the back and forth work.

[0026] Example 2

[0027] Please refer to Figures 2-3 The difference between example 1 and example 2 is that the high-speed conveying belt 4 is further provided with a guide and correction assembly for guiding the paper 5 on the high-speed belt, the guide and correction assembly comprises two track side plates 13 symmetrically arranged on the upper end of the high-speed conveying belt 4, the outer side of the track side plate 13 is connected with a track pushing rod 14 for adjusting the distance between the two, and the end of the track side plate 13 is provided with a guide inclined plate 15 for guiding the paper 5 on the high-speed belt to be corrected, the included angle between the guide inclined plate 15 and the track side plate 13 is thirty degrees, and the track side plate 13 is slidingly arranged on the upper end surface of the high-speed conveying belt 4. When the paper 5 on the high-speed belt is transported along with the high-speed conveying belt 4, the paper 5 on the high-speed belt will slide along the inclined surface of the guide inclined plate 15, and then slide from the gap between the two track side plates 13, thereby completing the correction.

[0028] Example 3

[0029] Please refer to Figures 2-3Different from example 2, the high-speed conveying small belt 6 is connected with a displacement assembly for driving the position of the high-speed conveying small belt 6 to be finely adjusted, the displacement assembly comprises a displacement seat 17 arranged above the high-speed conveying small belt 6, the lower end of the displacement seat 17 is connected with the shaft end of the high-speed conveying small belt 6 through a hanger, the outer side of the displacement seat 17 is connected and fixed with the buffer box through a positioning connecting rod 16, and the displacement seat 17 is connected with a threaded pusher for driving the displacement seat 17 to move along the transmission direction of the high-speed conveying small belt 6; under the action of the threaded pusher, the high-speed conveying small belt 6 will carry the adsorbed paper to be displaced, so as to make the paper 5 on the high-speed belt cooperate with the paper 8 on the low-speed belt.

[0030] The threaded pusher comprises a transmission block 18 arranged at the upper end of the displacement seat 17, a threaded hole is arranged through the transmission block 18, a threaded rod 19 is arranged in the threaded hole in a matched mode, one end of the threaded rod 19 is connected with a displacement motor 11 for driving the threaded rod 19 to rotate, and one side of the displacement seat 17 is arranged in a sliding mode with a fixed seat; under the action of the displacement motor 11, the threaded rod 19 and the transmission block 18 rotate relative to each other, and under the action of the thread, the displacement seat 17 will carry the high-speed conveying small belt 6 to be displaced; here, the threaded transmission is adopted to ensure the stability of the transmission.

[0031] One side of the low-speed conveying belt 9 is provided with a detection probe 12 for detecting the positions of the paper 8 on the low-speed belt and the paper 5 on the high-speed belt; the detection probe 12 obtains the displacement positions of the two papers to be superposed from the side, so as to provide an adjustment reference for the displacement assembly.

[0032] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and the present application can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application.
