Description

Technical Field

[0001] This utility model belongs to the field of printing equipment technology, and more specifically, it relates to a printing paper feeding platform structure. Background Technology

[0002] Large printing presses are essential equipment for many printing plants due to their high printing efficiency. The feed inlet of large printing presses is transported by forklifts to hold stacked paper. After the stacks are placed in the corresponding positions at the feed inlet, the paper is fed into the printing press one sheet at a time through the paper feeding nozzle. However, when a large amount of paper is stacked on the stacks, the paper stacks are too high, and the distance between the nozzle and the paper during the feeding process is too far, which can easily lead to interruption of the paper feeding. In this special case of paper feeding interruption, the stacks need to be raised again, which reduces the printing efficiency.

[0003] Therefore, in view of this, we will study and improve the existing structure and its shortcomings, and provide a printing paper feeding platform structure in order to achieve a more practical purpose. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a printing paper feeding platform structure to solve the problem that, under special circumstances, the container needs to be continuously raised when stacked papers are fed into the feed inlet of a large printing press, resulting in reduced printing efficiency.

[0005] The purpose and effect of this utility model's printing paper feeding platform structure are achieved by the following specific technical means:

[0006] A printing paper feeding platform structure includes a frame, a placement platform is provided inside the frame, side strips are provided on the four side walls of the frame, vertical grooves are provided on the side strips, and a movable block is slidably disposed in the grooves. Telescopic rods are provided at the four corners of the placement platform, the telescopic rods are inserted through the movable blocks, the movable blocks are connected to the placement platform by tension springs, and the movable blocks are connected to the frame by a lifting mechanism.

[0007] Furthermore, the lifting mechanism includes a chain, and sprockets are rotatably connected to the upper and lower ends of the frame sidewall. The two sprockets are connected by a chain, one link of the chain is threaded onto the moving block, and one sprocket is driven by a motor.

[0008] Furthermore, the sprocket shaft on one side of the frame passes through the frame and is connected to a driving wheel and a driven wheel respectively, and the driving wheel and the driven wheel are connected by a belt.

[0009] Furthermore, a baffle is provided at the top front side of the frame, and a crossbeam is provided inside the baffle. The motor is mounted on the crossbeam and connected to the sprocket shaft.

[0010] Furthermore, limiting protrusions are symmetrically arranged on both sides of the surface of the placement platform.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] By setting up the moving block, the placement platform moves up and down with the moving block after being stretched by the tension spring. When the placement platform is placed with a container for stacked paper, the tension spring is in a stretched state. The lifting mechanism drives the placement platform to the corresponding height and then feeds the paper. As the paper decreases and the weight decreases, the tension spring pulls the placement platform to rise automatically, so that the top paper can stay close to the suction nozzle and avoids the paper from being too far away from the suction nozzle, which would cause the paper to be interrupted.

[0021] Example:

[0022] As attached Figure 1 To be continued Figure 3 As shown:

[0023] This utility model provides a printing paper feeding platform structure, including a frame 1, and a placement platform 2 is provided inside the frame 1. The frame 1 is the frame 1 outside the paper feeding inlet of a large printing press. The placement platform 2 is used to place the paper to be printed. The paper is fed into the printing press one sheet at a time through the suction nozzle of the paper feeding mechanism at the printing press inlet.

[0024] The frame 1 has side strips 3 on all four side walls. The side strips 3 have vertical grooves 301. The sliding blocks 11 are slidably arranged in the grooves 301. The placement platform 2 has telescopic rods 12 at all four corners. The telescopic rods 12 pass through the corresponding sliding blocks 11. The sliding blocks 11 are connected to the placement platform 2 by tension springs 13. The placement platform 2 is suspended in the frame 1 by the four sliding blocks 11. The four sliding blocks 11 drive the placement platform 2 to rise and fall smoothly.

[0025] The moving block 11 is connected to the frame 1 through a lifting mechanism. The placement platform 2 is stretched by the tension spring 13 and moves up and down with the moving block 11. When the placement platform 2 is placed with a container for stacked paper, the tension spring 13 is in a stretched state. The lifting mechanism drives the placement platform 2 to the corresponding height and then feeds the paper. As the paper decreases and the weight decreases, the tension spring 13 pulls the placement platform 2 to rise automatically, so that the top paper can stay close to the suction nozzle and avoid the paper feeding being interrupted due to being too far away from the suction nozzle.

[0026] The lifting mechanism includes a chain 5. Sprockets 4 are rotatably connected to the upper and lower ends of the sidewall of the frame 1. The two sprockets 4 are connected by the chain 5. One link of the chain 5 passes through the moving block 11. One of the sprockets 4 is driven by a motor 10. Figure 3 As shown, a baffle 14 is provided on the top front side of the frame 1, and a crossbeam 9 is provided inside the baffle 14. The motor 10 is mounted on the crossbeam 9 and connected to the shaft of the sprocket 4. The baffle 14 prevents the motor 10 from being touched when the paper is transported from the outside, thus providing good protection. The motor 10 drives the sprocket 4 to rotate, which causes the chain 5 to drive the moving block 11 to lift the placement platform 2.

[0027] The sprocket 4 on one side of the frame 1 passes through the frame 1 and is connected to the driving wheel 6 and the driven wheel 7 respectively. The driving wheel 6 and the driven wheel 7 are connected by the belt 8, so that the motor 10 can drive the two moving blocks 11 on one side to lift at the same time, reducing energy consumption and balancing the placement platform 2.

[0028] The placement platform 2 has symmetrically arranged limiting protrusions 201 on both sides of its surface to limit the position of the container when it is placed on the placement platform 2, thus preventing the paper from shifting.

[0029] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
