Description

Technical Field

[0001] This utility model relates to the field of paper feeding mechanism technology, and in particular to an automatic paper feeding correction mechanism with adaptive friction adjustment. Background Technology

[0002] In modern office automation, printing and publishing, and document processing, efficient and stable paper feeding is crucial for ensuring normal equipment operation and high-quality output. During operation, deviations in paper feeding in printers, copiers, and printing presses can lead to skewing of printed content, misregistration, severely impacting output quality and even causing paper waste and equipment malfunction. In document processing systems, paper feeding deviations can result in incorrect document information reading, affecting the accuracy and efficiency of business processing. As industries increasingly demand higher office efficiency and product quality, higher standards are being placed on the stability and reliability of paper feeding mechanisms.

[0003] In the existing technology, printers, copiers and other equipment require a paper feeding mechanism to transport external paper to the equipment for printing. However, traditional paper feeding mechanisms are simple in structure and poor in functionality, which means that they cannot handle paper that has shifted to one side during the paper feeding process. This results in the subsequent printing process only being able to print on one side of the paper, which seriously affects the printing effect and also wastes paper. Utility Model Content

[0004] This utility model mainly provides an automatic paper feeding correction mechanism that can correct misaligned paper to avoid affecting subsequent printing results.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an adaptive friction force adjustment automatic paper feeding correction mechanism, comprising a mounting frame, a first motor fixedly mounted on the top of the mounting frame, a first gear fixedly sleeved on the output end of the first motor, two movable slots opened on the inner surface wall of the mounting frame, two movable frames movably embedded in the inner surface wall of each of the two movable slots, a lead screw movably inserted between the inner surface walls of each of the two movable slots, and the outer surface wall of the lead screw being threadedly connected to the inner surface wall of the movable frame, a second gear fixedly sleeved on the outer surface wall of one of the two lead screws, and the outer surface wall of the second gear meshing with the outer surface wall of the first gear, a transmission wheel fixedly sleeved on the outer surface wall of each of the two lead screws, a chain movably sleeved between the outer surface walls of the two transmission wheels, and the outer surface wall of the transmission wheel meshing with the inner surface wall of the chain.

[0006] Preferably, each of the four movable frames has a set of embedding slots on its outer surface wall, and a fixed frame is movably embedded in the inner surface wall of each of the four sets of embedding slots. Under the action of other structures, the fixed frame can move up and down inside the embedding slot.

[0007] Preferably, rollers are movably inserted between the inner walls of the four sets of fixing frames. A second motor is fixedly installed on one side of the outer wall of four of the four sets of fixing frames, and the output end of the second motor is fixedly connected to the inner wall of four of the rollers. A support frame is fixedly installed on one side of the outer wall of the mounting frame, and a vision sensor is fixedly inserted into the inner wall of the support frame. Under the action of the second motor, the rollers can be driven to rotate to transport the paper. Under the action of the vision sensor and the external detection system, it can be determined whether the paper has shifted to one side and correct it.

[0008] Preferably, a return spring is fixedly installed on one side of the inner wall of each of the four movable frames, and the outer wall of the return spring is fixedly connected to the outer wall of the fixed frame. Under the action of the return spring, a squeezing force can be applied to the fixed frame, thereby allowing the paper to be transported smoothly.

[0009] Preferably, a mounting platform is fixed to one side of the outer wall of the mounting frame, and a first fixing block is fixedly installed at the bottom of the inner wall of the mounting platform. Under the action of the first mounting block, other structures can be limited, thereby improving their performance.

[0010] Preferably, a telescopic rod is movably sleeved on the outer wall of the first fixing block, and an adjusting plate is movably inserted between the inner walls of the mounting platform. The angle of the adjusting plate can be adjusted by the telescopic rod, thereby improving the real-time paper handling effect.

[0011] Preferably, a second fixing block is fixedly installed on one side of the outer wall of the adjusting plate, and the outer wall of the second fixing block is movably connected to the telescopic end of the telescopic rod. Under the action of the second fixing block, the telescopic rod can work normally, improving the effectiveness of the device.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, during the paper conveying process, the paper position information can be collected by a vision sensor and detected by an external detection system. When the paper is detected to be shifted to one side, the lead screw can be driven to rotate through the cooperation of the first motor, the first gear, the second gear, and other structures. The rotation of the lead screw drives the movable frame and rollers to carry the paper to the facility position, preventing the paper from shifting to one side when it is conveyed into the printer, copier, or other equipment. This improves the subsequent printing effect and the practicality of the device, and avoids paper waste.

[0014] 2. In this utility model, when paper needs to be conveyed, the adjusting plate can be adjusted to a suitable angle by the action of the first fixing block, the second fixing block and the telescopic rod, and then the paper can be placed and conveyed. At the same time, the conveying effect and conveying efficiency of the paper are greatly improved by the cooperation of the return spring and the roller. Attached Figure Description

[0023] like Figures 1-4 As shown: Each of the four movable frames 10 has a set of embedding slots 15 on its outer surface wall, and each of the four sets of embedding slots 15 has a fixed frame 16 movably embedded in its inner surface wall. Under the action of other structures, the fixed frame 16 can move up and down inside the embedding slot 15.

[0024] like Figure 3 , Figure 4 As shown: Rollers 18 are movably inserted between the inner walls of the four sets of fixed frames 16. A second motor 19 is fixedly installed on one side of the outer wall of four of the four sets of fixed frames 16, and the output end of the second motor 19 is fixedly connected to the inner wall of four of the rollers 18. A support frame 20 is fixedly installed on one side of the outer wall of the mounting frame 1. A vision sensor 21 is fixedly inserted into the inner wall of the support frame 20.

Under the action of the return spring 17, a squeezing force can be applied to the fixed frame 16, so that the paper can be smoothly conveyed.

[0026] like Figure 1 , Figure 2 As shown: A mounting platform 2 is fixed on one side of the outer wall of the mounting bracket 1.
