Description

Technical Field

[0001] The utility model relates to the technical field of paper processing, and particularly relates to a paper page flipping device. Background Art

[0002] In the technical field of paper processing, the flipping and transmission of paper pages are important links. With the improvement of the automation level, the traditional methods of paper flipping and transmission can no longer meet the requirements of modern production. The traditional paper page flipping methods may have problems such as unstable flipping, easy paper jamming, and low transmission efficiency. In addition, the characteristics of paper such as size and material also increase the difficulty of paper page flipping.

[0003] After retrieval, the Chinese patent document application number: 201220180113.0, discloses a coating flipping drying device for the outer bag paper of fruit-growing bags, which includes a common inverted scraper coating device, a paper page flipping device, and a drying cylinder drying device arranged in sequence along the paper movement direction. The paper page flipping device includes five guiding rollers arranged along the paper movement direction, wherein the first guiding roller is perpendicular to the paper movement direction, the second and fifth guiding rollers form an angle of 45° and 135° with the paper running direction, and the third and fourth guiding rollers are in the same direction as the paper running direction. Through paper page flipping, it can prevent the coating layer from contacting the drying cylinder, resulting in adhesion or the phenomenon of paper page wrinkles caused by insufficient tension when drying with a blower. This device has simple equipment and convenient operation.

[0004] However, the above-mentioned coating flipping drying device for the outer bag paper of fruit-growing bags still has the following defects:

[0005] This solution proposes to flip by bending the paper, but the flipping objects are different. According to different flipping objects, the coating equipment may be different. During the paper coating process, conventional equipment can only coat one side of the paper regardless of the number of coating devices. For some special papers, both sides of the paper need to be coated. Usually, after one side of the paper is coated, the other side is coated again, but this not only has low efficiency, high cost, but also is difficult to guarantee the quality. Therefore, we need a paper page flipping device to solve the above problems. Summary of the Utility Model

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-4 , the present invention provides a technical solution: a paper page flipping device, including a flipping table 1. Support components are installed on both sides of the surface of the flipping table 1. A roller 11 is arranged inside the support components. A first cylinder 6 is arranged above the surface of the flipping table 1. A first paper inlet 603 for paper pages to be put in is opened at the lower end of the outer wall of the first cylinder 6. A first paper outlet 602 for paper pages to pass through is opened on one side of the outer wall of the first cylinder 6. A second cylinder 8 is arranged above the first cylinder 6. The second cylinder 8 is arranged opposite to the first cylinder 6. A second paper inlet 802 for paper pages to enter is opened on one side of the outer wall of the second cylinder 8.

Fixing components are arranged below both the first cylinder 6 and the second cylinder 8, and the fixing components are installed on the side close to the roller 11;

[0024] When in use, the paper pages are put in through the first paper inlet 603 of the first cylinder 6, then pass through the first paper outlet 602, and then the paper pages are sent into the second paper inlet 802 of the second cylinder 8 through the rotation of the roller 11, and then pass through the second paper outlet 803 of the second cylinder 8. Due to the relative position design of the second cylinder 8 and the first cylinder 6, the paper pages will experience a flipping action after entering the second cylinder 8. The flipped paper pages pass through the second paper outlet 803 of the second cylinder 8. The flipping process is stable and reliable, which can ensure that the paper will not be wrinkled or damaged after flipping, realizing precise paper flipping and stable structural layout, and solving the problems of instability, low efficiency and unreasonable structural layout existing in traditional paper flipping devices.

[0025] The support components include a first support frame 2 and a second support frame 3. The bottom ends of the first support frame 2 and the second support frame 3 are fixedly installed on the surface of the flipping table 1. A driving motor 10 is fixedly installed on the side wall of the first support frame 2. The output shaft of the driving motor 10 passes through the side wall of the first support frame 2 and is fixedly connected to the roller shaft of the roller 11. One end of the roller shaft of the roller 11 is rotatably installed on the inner wall of one side of the second support frame 3.
