Description

Technical Field

[0001] The invention relates to the technical field of copying of a copying and printing all-in-one machine, and more specifically to a rust-proof super-hard flip bracket of a copying and printing all-in-one machine and a printing device. Background Art

[0002] Batch copying is a printing method that improves office efficiency. It allows users to print multiple copies of the same or different documents at one time. When copying documents, there is a need for batch copying, such as meeting materials, training materials, copies of legal documents, and contracts. Batch copying can complete a large number of document copies in a short time. Batch copying not only saves the time of copying each document individually, but also maintains the consistency of the documents and reduces operational errors.

[0003] The prior art CN215590299U patent document proposes a flipping device and a printing device, wherein the flipping device includes: a frame; a guide roller, the guide roller is rotatably arranged on the frame along a first direction; a first flip roller, the first flip roller is installed on the frame; a second flip roller, the second flip roller is installed on the frame, the first flip roller and the second flip roller are spaced apart from each other in a second direction and are both inclined relative to the first direction, and the inclination directions of the first flip roller and the second flip roller are opposite; paper enters the frame along the first direction, the paper wraps around the first flip roller and is output from a third direction until it wraps around the guide roller, and then the paper reaches the second flip roller along the third direction, and finally wraps around the second flip roller to complete the flipping of the paper and output it. Through the above method, the embodiment of the utility model can flip the paper and improve the printing efficiency of the printing device. When copying multiple double-sided documents, the flipping mechanism can only flip and copy the paper documents one by one, and it is difficult to flip and copy multiple paper documents at the same time. When flipping and copying multiple documents of the same specification, the staff needs to continuously put the documents into the printing device, which reduces the use efficiency of the printing device. In view of this, we propose a rust-proof and super-hard flip bracket for a copying and printing all-in-one machine and its processing equipment. Summary of the invention

During the tilting process of the lower paperboard 402, the shielding frame 502 can be driven to tilt through the support rod 402a. By separating the shielding frame 502 from the shielding frame 1 501, the shielding cloth 503 is unfolded. In this project, external light can be prevented from irradiating into the interior of the copier and affecting the copying effect of paper documents.

[0028] In an embodiment of the present invention, Figure 5 and Figure 6 As shown, the flip unit 6 includes a transmission rod 601, which is movably sleeved inside the flip cylinder 101, a gear 602 is fixedly sleeved on the outer wall of the transmission rod 601, a flip frame 603 is fixedly sleeved on the outer wall of the transmission rod 601, and the flip frames 603 are distributed in a linear array, and a plurality of flip grooves 604 are opened on the outer wall of each flip frame 603, and the flip grooves 604 are distributed in a ring array, and the inner walls on both sides of each flip groove 604 are movably connected to extension brackets 605 through hinges, and the two extension brackets 605 are fixedly connected to springs 2 606 on opposite sides, and the tops of the two extension brackets 605 are movably connected to air bags 607 through hinges, and the tops of the air bags 607 are fixedly connected to flip strips 607a, so that the paper is moved into the flip cylinder 101 through the roller 2 412 after copying. The turning frame 603 is rotated, and then the gear 602 is rotated by the external circuit mechanism, and the transmission rod 601 rotates to drive the turning frame 603 to rotate. During the rotation process, the two extension brackets 605 are pressed against the spring 2 606 by centrifugal force, which can shorten the distance between the airbag 607 and the inner wall of the turning cylinder 101. When the paper enters the turning cylinder 101, the turning bar 607a on the airbag 607 contacts the paper document, increasing the friction force, and the paper moves on the inner wall of the turning cylinder 101 and moves out from the notch on the turning cylinder 101, so that the paper on the uncopied side contacts the glass panel, and then moves on the moving frame through the scanning unit 3 to scan the paper. When copying the other side of the paper, the paper is moved on the lower paperboard 402 through the paper lowering mechanism 4 to prepare for copying the next document.

[0029] As another embodiment of the present invention, Figure 4As shown, the paper discharge unit 7 includes a paper discharge port 701, which is provided on one side of the copier and printer body 1, a placement rack 702 is fixedly connected to one side of the copier and printer body 1, and rebound plates 703 are movably connected to the inner walls on both sides of the paper discharge port 701, and torsion springs 704 are respectively fixedly connected to the two sides of the rebound plate 703, and one end of the torsion spring 704 is fixedly connected to the inner walls on both sides of the paper discharge port 701, a fault 702a is arranged on the top of the placement rack 702, and a placement plate 702b is fixedly connected inside the placement rack 702, and the top of the placement plate 702b is an inclined surface 702b-1. After the copying of a single document is completed, the roller 412 rotates counterclockwise to move the paper on the glass panel. When the paper moves to the paper outlet 701, the rebound plate 703 can be offset outward, and the paper moves out from the gap between the rebound plate 703 and the glass panel and moves from the placement rack 702. When the paper passes through the fault 702a, the paper moves to the placement plate 702b. Since the surface of the placement plate 702b is an inclined surface 702b-1, the paper gathers to one side. After the paper document is moved out, the force exerted on the rebound plate 703 by the torsion spring 2 704 makes the rebound plate 703 return to its initial position. After the paper printing is completed, the next paper moves to the glass panel and is copied. The other side is copied through the flip cylinder 101, and the paper moves outward through the paper outlet 701.

[0030] Working principle: This embodiment provides a rust-proof super-hard flip bracket and printing equipment for a copier and printer. When using the copier and printer body 1, first press one end of the lower paperboard 402 to tilt the lower paperboard 402. During the tilting process of the lower paperboard 402, the shielding frame 2 502 can be driven to tilt through the support rod 402a. By separating the shielding frame 2 502 from the shielding frame 1 501, the shielding cloth 503 is unfolded. In this project, external light can be prevented from irradiating the inside of the copier and affecting the copying effect of paper documents. In this process, the tilted lower paperboard 402 can be stabilized by the telescopic rod 504. When in use, first place the paper On the lower paperboard 402, one side of the paper is against the baffle 404, and then the lower pressure frame 405 is manually adjusted and the pressure cylinder 406 is pressed on the paper to rotate at a constant speed through the torsion spring 1 407. The paper moves downward from the top, passes through the paper discharge roller 409, and moves out of the paper discharge slot 505. The paper document moves from the lower paperboard 402 to the glass panel to copy the paper document. After copying, the paper is moved into the flip cylinder 101 through the roller 2 412, and then the gear 602 is rotated through the external circuit mechanism, and the transmission rod 601 rotates to drive the flip frame 603 to rotate. During its rotation, the two extension brackets 605 are pushed toward the spring 2 603 by centrifugal force. 06 squeeze, can shorten the distance between the airbag 607 and the inner wall of the turning cylinder 101, when the paper enters the turning cylinder 101, the turning bar 607a on the airbag 607 contacts the paper document, increases the friction force, the paper moves on the inner wall of the turning cylinder 101, moves out from the notch on the turning cylinder 101, makes the paper on the uncopied side contact with the glass panel, and then moves on the moving frame through the scanning unit 3 to scan the paper, when copying the other side of the paper, the paper is moved on the lower paperboard 402 through the paper lowering mechanism 4 to prepare for copying the next document, after the single document is copied, the roller 2 412 rotates counterclockwise to make the paper move on the glass panel, the paper When moving to the paper outlet 701, the rebound plate 703 can be offset outward, and the paper is moved out from the gap between the rebound plate 703 and the glass panel and moved from the placement rack 702. When the paper passes through the fault 702a, the paper moves to the placement plate 702b. Since the surface of the placement plate 702b is an inclined surface 702b-1, the paper gathers to one side. After the paper document is moved out, the force exerted on the rebound plate 703 by the torsion spring 2 704 makes the rebound plate 703 return to its initial position. After the paper printing is completed, the next paper moves to the glass panel and is copied. The other side is copied through the flip cylinder 101, and then the paper is moved out through the paper outlet 701.
