Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, and in particular to an anti-wrinkle paper flattening mechanism. Background Technology

[0002] Resource recycling, an economic development model based on the continuous reuse of materials, is becoming a global trend. The strategy of sustainable development has gained widespread consensus. Sustainable development, as discussed here, refers to development that meets the needs of the present without compromising the ability of future generations to meet their own needs. It means paying attention to both the quantity and quality of economic growth. A key indicator of this is the perpetual utilization of resources and the maintenance of a healthy ecological environment. Currently, there is a need for recyclable resources in office buildings and homes, such as paper recycling. To improve paper utilization, we should strive to make full use of both sides of the paper, meaning both sides can be used for printing. However, paper wrinkles after printing on one side, making it unsuitable for reprinting. Placing wrinkled paper in a printer can easily cause paper jams.

[0003] Chinese utility model patent (authorization announcement number: CN219486987U, title: A material flattening and sorting device) includes a pressing platform and two side baffles. Multiple bases are provided on the lower surface of the pressing platform, and the side baffles are located on the upper surface of the pressing platform. Multiple support seats are provided on the upper surface of the side baffles, and connecting seats are slidably connected to the outer surfaces of the multiple support seats. The beneficial effects of this utility model are: under the movement of the fixed seat and the sliding seat, the paper is pressed and fixed between the side baffles and the fixed and sliding seats, making the paper's position relatively stable and preventing skewing during the pressing process. When the paper is pressed by the pressing seat, it is slowly flattened. Under the action of the side baffles, the fixed seat, and the sliding seat, skewing of the paper during flattening is prevented, which would be detrimental to the normal flattening process. However, its working efficiency is low, and the labor intensity of workers is high. Utility Model Content

[0004] The purpose of this invention is to provide a paper-flattening mechanism to prevent wrinkles, thereby overcoming the shortcomings of the prior art.

[0005] The purpose of this utility model is achieved through the following technical solution: a paper flattening mechanism for preventing wrinkles, including a worktable and a flattening component, wherein the flattening component is used to roll the paper on the worktable, and also includes a belt conveyor, wherein the worktable is fixed inside the frame of the belt conveyor, the upper belt of the belt conveyor is attached to the surface of the worktable, and a gantry frame is fixed on the frame of the belt conveyor, wherein the gantry frame is used to support the flattening component above the worktable.

[0006] Preferably, the flattening component includes a hydraulic cylinder and a connecting rod. The hydraulic cylinder is fixed on the gantry frame, and the piston rod of the hydraulic cylinder passes through the gantry frame. The connecting rod is a pair and is hinged to the piston rod in a figure-eight shape. A U-shaped arm is fixed to the end of the connecting rod away from the hydraulic cylinder, and a roller is rotatably installed inside the U-shaped arm.

[0007] Preferably, a pressure plate is also fixed on the piston rod, the pressure plate is located above the connecting rod, and a movable plate is also fitted on the pair of connecting rods. Guide rods penetrating the pressure plate are fixed at the four corners of the movable plate, and springs are fitted on the guide rods. The springs are compressed and installed between the pressure plate and the movable plate.

[0008] Preferably, the guide rod is a lead screw, and a nut is screwed onto one end of the guide rod that passes through the pressure plate.

[0009] Preferably, a pair of rollers are rotatably mounted on the movable plate, and the rollers are respectively pressed against the corresponding connecting rods, with the rotation axis of the rollers parallel to the rotation axis of the connecting rods.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] The paper is conveyed to the flattening unit by a belt conveyor for rolling, which avoids manual paper handling and reduces the risk of finger injuries. At the same time, when the previous paper is flattened, the next paper to be flattened is laid, which improves work efficiency. In addition, there is no need to manually turn the screw to press down the squeezing platform, which reduces the labor intensity of workers. Attached Figure Description

[0023] like Figure 1 and2 As shown, an anti-wrinkle paper flattening mechanism includes a worktable 1 and a flattening component. The flattening component is used to roll the paper on the worktable 1. It also includes a belt conveyor 2. The worktable 1 is fixed inside the frame of the belt conveyor 2. The upper belt of the belt conveyor 2 is attached to the table surface of the worktable 1. A gantry frame 3 is fixed on the frame of the belt conveyor 2. The gantry frame 3 is used to support the flattening component above the worktable 1. The paper is transported to the flattening component for rolling by the belt conveyor 2, avoiding manual handling of paper and reducing the risk of finger injuries. At the same time, when the previous paper is flattened, the next paper to be flattened is laid out, improving work efficiency. In addition, there is no need to manually turn the screw to press down the pressing platform, reducing the labor intensity of workers.

[0024] In this embodiment, as Figure 1 and 3 As shown, the flattening component includes a hydraulic cylinder 4 and a connecting rod 5. The hydraulic cylinder 4 is fixed on the gantry frame 3, and the piston rod of the hydraulic cylinder 4 passes through the gantry frame 3. The connecting rod 5 is a pair and is hinged to the piston rod in a figure-eight shape. A U-shaped arm is fixed to the end of the connecting rod 5 away from the hydraulic cylinder 4. A roller 6 is rotatably installed inside the U-shaped arm. The structure is simple and easy to use, and the rolling and flattening makes the paper flatter and smoother.

[0025] In this embodiment, as Figure 1 and 3 As shown, a pressure plate 7 is also fixed on the piston rod. The pressure plate 7 is located above the connecting rod 5. A movable plate 8 is also fitted on a pair of connecting rods 5. Guide rods 9 that pass through the pressure plate 7 are fixed at the four corners of the movable plate 8. Springs 10 are fitted on the guide rods 9. The springs 10 are compressed and installed between the pressure plate 7 and the movable plate 8. The springs 10 cause the rollers 6 to provide greater pressure on the paper, shortening the time for the paper to be flattened.

[0026] In this embodiment, as Figure 1 and 3 As shown, the guide rod 9 is a lead screw, and a nut 11 is screwed onto one end of the guide rod 9 that passes through the pressure plate 7. The compression degree of the spring 10 is adjusted by screwing the nut 11 to adapt to the flattening requirements of paper of different thicknesses and materials.

[0027] In this embodiment, as Figure 2 and 4 As shown, rollers 12 are rotatably mounted on the movable plate 8. There is a pair of rollers 12, which abut against the corresponding connecting rods 5. The rotation axis of the rollers 12 is parallel to the rotation axis of the connecting rods 5, which reduces the wear on the connecting rods 5 and extends their service life.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
