DETAILED DESCRIPTION

[0034] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0035] Example 1

[0036] like Figure 1-Figure 3 As shown, this embodiment provides a paper turning mechanism, including a first paper feeding assembly 111, a paper guide 112 and a swing paper feeding assembly 113;

[0038] The swing-type paper feeding assembly 113 is installed at the lower left of the first paper feeding assembly 111, and its paper outlet faces upward. A paper guide 112 is provided between the paper outlet of the swing-type paper feeding assembly 113 and the paper outlet of the first paper feeding assembly 111. The paper guide 112 is used to directly feed out or guide the paper fed by the first paper feeding assembly 111 to the paper outlet of the swing-type paper feeding assembly 113.

[0039] The swing-type paper feeding assembly 113 can swing to a position where its paper outlet faces upward and receives paper fed out of the paper outlet of the first paper feeding assembly 111, or swing to a position where its paper outlet is close to the paper inlet below the first paper feeding assembly 111, and flips the received paper over and feeds it to the first paper feeding assembly 111. The structure is simple, and the paper guide is used to divert the paper at the paper outlet of the first paper feeding assembly. If the paper needs to be directly output, the paper guide directly feeds the paper out. If the paper needs to be flipped over, the paper guide guides the paper to the swing-type paper feeding assembly, and the swing-type paper feeding assembly flips the paper over and feeds it to the first paper feeding assembly.

[0040] The paper guide 112 in the above technical solution includes an arc-shaped paper guide 1121 and a first rotating driving member. The paper guide 1121 is arranged along the front-to-back direction, and its arc opening faces the lower right. The driving end of the first rotating driving member is transmission-connected to the paper guide 1121. The first rotating driving member is used to drive the paper guide 1121 to rotate to directly deliver or guide the paper delivered from the paper outlet of the first paper feeding assembly 111 to the paper outlet of the swing-type paper feeding assembly 113. The structure is simple and the paper guiding is convenient.

[0041] The above technical solution also includes a second paper feeding assembly 114a, which is arranged between the paper guide 112 and the swing paper feeding assembly 113, and the paper feed port of the second paper feeding assembly 114a faces upward, and the paper guide 112 is used to directly feed out or guide the paper fed by the first paper feeding assembly 111 to the paper feed port of the second paper feeding assembly 114a;

[0042] The paper outlet of the second paper feeding assembly 114a faces downward, and the swing-type paper feeding assembly 113 can swing to a position where its paper outlet faces upward and receives paper fed out of the paper outlet of the second paper feeding assembly 114a, or swing to a position where its paper outlet is close to the paper inlet below the first paper feeding assembly 111, so that the structure of the swing-type paper feeding assembly can be smaller, thereby making the volume of the entire paper turning mechanism smaller (such as Figure 2 The paper guide in the paper feeding assembly directly feeds the paper fed by the first paper feeding assembly over the paper guide, and Figure 3 The middle paper guide intercepts the paper sent out by the first paper feeding assembly and guides it to the second paper feeding assembly for sending out).

[0043] The above technical solution also includes a third paper feeding assembly 114b, which is arranged below the first paper feeding assembly 111 and has a paper inlet and a paper outlet. The paper outlet of the third paper feeding assembly 114b is close to the paper inlet below the first paper feeding assembly 111. The swing-type paper feeding assembly 113 can swing to a position where its paper outlet is close to the paper inlet of the third paper feeding assembly 114b to convey the received paper to the third paper feeding assembly 114b, and the third paper feeding assembly 114b conveys the paper to the paper inlet below the first paper feeding assembly 111. This can further make the structure of the swing-type paper feeding assembly more compact, thereby making the volume of the entire paper turning mechanism more compact.

[0044] In the above technical solution, the second paper feeding assembly 114a and the third paper feeding assembly 114b both include a first active transmission belt 1141 and a first driven transmission belt 1142 that fit each other, and the first active transmission belt 1141 drives the corresponding first driven transmission belt 1142 to rotate, and the corresponding first active transmission belt 1141 and the first driven transmission belt 1142 that fit each other form their paper feeding channels, which have a simple structure and are convenient for paper feeding, and at the same time, the paper will not be wrinkled during transportation. Among them, the paper feeding directions of the second paper feeding assembly and the third paper feeding assembly remain unchanged.

[0045] The swing-type paper feeding assembly 113 in the above technical solution includes a bracket 1131, a second rotating driving member and a paper receiving assembly 1132. The paper receiving assembly 1132 is rotatably mounted on the bracket 1131. The second rotating driving member is mounted on the bracket 1131, and its driving end is transmission-connected to the paper receiving assembly 1132. The paper receiving assembly 1132 has a vertically arranged paper receiving channel, and the upper end of its paper receiving channel constitutes its paper outlet. The second rotating driving member is mounted on the bracket 1131, and is used to drive the paper receiving assembly 1132 to swing left and right until its paper outlet is close to the paper outlet of the second paper feeding assembly 114a or the paper inlet of the third paper feeding assembly 114b. It has a simple structure and is easy to turn over the paper.

[0046] The paper receiving assembly 1132 in the above technical solution includes a second active transmission belt 11321 and a second driven transmission belt 11322 that fit each other, the second active transmission belt 11321 drives the second driven transmission belt 11322 to rotate, and the side where the second active transmission belt 11321 and the second driven transmission belt 11322 are close to each other constitutes the paper receiving channel, which has a simple structure and will not cause paper wrinkles when turning over the paper. Among them, when receiving paper, the paper receiving assembly completely enters the paper sent out by the second paper feeding component through the paper outlet between the second active transmission belt and the second driven transmission belt, and then the second rotating drive member drives the paper receiving assembly to swing until its paper outlet is aligned with the paper feed outlet of the third paper feeding component, at which time the second active transmission belt and the second driven transmission belt of the paper receiving assembly rotate in the opposite direction to send the paper from the paper outlet to the paper feed outlet of the third paper feeding component.

[0047] Among them, the first paper feeding assembly can be a full-suction type turning mechanism disclosed in document number CN112721467A "A full-suction type turning mechanism and a printing device composed of it" or a semi-suction type turning mechanism disclosed in CN112721468A "Positioning ventilation roller, semi-suction type turning mechanism and printing device".
