Description

Technical Field

[0001] The utility model relates to the technical field of printing machine equipment, in particular to a printing machine paper delivery platform with an angle adjustment mechanism. Background Art

[0002] A printing press is a machine that prints text and images. Modern printing presses are generally composed of mechanisms such as plate loading, inking, pressing, and paper feeding. Its working principle is: first, the text and image to be printed are made into a printing plate, and then ink is applied to the place where the text and image are on the printing plate by hand or a printing machine, and then directly or indirectly transferred to paper or other substrates, thereby replicating a printed product that is the same as the printing plate.

[0003] After the printing work is completed, the collection and sorting of paper is a crucial process. There will be a paper collection device at the end of the printing press, which includes a paper collection platform. On the paper collection platform, workers will place a paper tray. This tray can not only carry a large amount of paper, but also facilitate later handling and transfer. As the printing press is running, the printed papers are conveyed to the tray one by one. Because the paper is conveyed at a very fast speed, there is often a situation: when the tail of the previous paper has not completely fallen on the tray, the next paper follows closely, which will cause the front end of the next paper to rub against the tail of the previous paper, causing the latter to be rubbed and damaged. This not only affects the overall quality of the paper, but may also cause trouble for subsequent processing and use.

[0004] In the prior art, workers usually raise a part of the tray away from the paper outlet, so that the tray forms an angle of inclination toward the paper outlet, and the height of the tray at the paper outlet is lower than the height of the tray away from the paper outlet. In this way, when the paper falls on the tray, the previous paper will fall completely on the tray, ensuring that each paper can be neatly stacked together to avoid friction and damage between them.

[0005] However, the existing method of raising the height is mainly to place an inclined block on the side of the tray away from the paper outlet. Although this method is simple, there is a problem: the height and angle of the block are often difficult to adjust accurately, resulting in the inclination angle of the tray being inaccurate, and sometimes even causing the paper to slip and fall unsteadily. This not only affects the efficiency of paper collection, but may also pose a potential threat to the quality of the paper.

[0006] Therefore, in order to further improve the efficiency and quality of paper collection work, a printing press paper collection platform with an angle adjustment mechanism is proposed to address the above problems. Utility Model Content

[0007] In order to solve the above problems, the utility model adds an adjustable platform on the paper collection platform, and the height in different directions can be adjusted respectively by four electric telescopic rods, and the adjustable platform can be adjusted according to the required inclination angle of the tray.

[0008] A printing press paper receiving platform with an angle adjustment mechanism comprises: a paper receiving platform, four corners of the paper receiving platform are respectively provided with connecting blocks, the four connecting blocks are respectively connected to the lifting mechanisms arranged in four supporting columns, four electric telescopic rods are installed on the upper surface of the paper receiving platform, and the power output ends of the electric telescopic rods are connected to the adjustable platform.

[0009] As a preferred technical solution of the present technical solution, in order to reduce the load on the electric telescopic rod and increase the service life, a buffer spring is provided between the paper collection platform and the adjustable platform.

[0010] As a preferred technical solution of the present technical solution, the electric telescopic rods are distributed in a circle around the center of the adjustable platform, so that the electric telescopic rods in various directions of the adjustable platform are evenly distributed.

[0011] As a preferred technical solution of the present technical solution, the lifting mechanism includes a motor installed at the upper end of a support column, a slide groove is opened inside the support column, a screw rod is arranged inside the slide groove, and a slider is arranged outside the screw rod.

[0012] As a preferred technical solution of the present technical solution, an upper limit block and a lower limit block are provided in the slide groove.

[0013] As a preferred technical solution of the present technical solution, in order to reduce the load caused by weight to the lifting mechanism and improve the service life, a buffer mechanism is provided between the slider and the connecting block. The buffer mechanism includes a mounting seat, a movable rod is provided inside the mounting seat, a spring is provided outside the movable rod, and the upper end of the movable rod is connected to the connecting block.

[0014] The technical effects of the utility model are:

[0015] The utility model adds an adjustable platform to the original paper collection platform. It meets the different tilt angles required for various trays when placing paper. Through four electric telescopic rods, the height of the platform in four different directions can be adjusted respectively to achieve the precise tilt angle required by the tray. It not only improves work efficiency, but also greatly reduces problems such as paper accumulation or slipping caused by improper tray tilting.

[0016] During the paper collection process, papers are continuously stacked on the paper collection platform, which increases the load-bearing capacity of the paper collection platform. This causes the part in contact with the slider to be under stress for a long time, affecting the service life of the equipment. The spring is used for buffering to reduce the load on the supporting connection between the slider and the paper collection platform due to weight, thereby increasing the service life.

[0022] Combine the following Figure 1-3 The embodiments of the present invention will be described in detail.

[0023] Please refer to Figure 1-3 A printing press paper delivery platform with an angle adjustment mechanism includes: a paper delivery platform 1, four corners of the paper delivery platform 1 are respectively provided with connecting blocks 10, the four connecting blocks 10 are respectively connected to the lifting mechanisms 3 arranged in four supporting columns 2, four electric telescopic rods 4 are installed on the upper surface of the paper delivery platform 1, and the power output end of the electric telescopic rod 4 is connected to the adjustable platform 5.

[0024] A buffer spring 6 is provided between the paper receiving platform 1 and the adjustable platform 5 .

[0025] The electric telescopic rods 4 are distributed in a circle around the center of the adjustable platform 5 .

[0026] The specific working process of the paper receiving platform of the printing press with the angle adjustment mechanism of this embodiment is as follows: when the printing press starts working, the staff first places the tray firmly on the paper receiving platform 1 in advance, and then slowly raises the paper receiving platform 1 through the lifting mechanism 3. When the paper receiving platform 1 is lifted to its highest point, the lifting mechanism will automatically sense and stop rising. After the paper receiving platform 1 rises to the predetermined position, the electric telescopic rod 4 adjusts the inclination of the adjustable platform according to the preset angle, so that the angle of the tray is tilted at the same time, so that the printed matter can be smoothly output from the printing press and slide onto the tray.

[0027] However, as the printed paper on the paper receiving platform 1 continues to increase, its weight will gradually increase. At this time, the buffer spring 6 can effectively absorb and disperse the pressure from the paper accumulation, reducing the burden on the electric telescopic rod 4. This can not only protect the electric telescopic rod 4 from damage, but also extend its service life and reduce maintenance costs.

[0028] Based on the above embodiments, refer to Figure 2 The lifting mechanism 3 includes a motor 30 installed at the upper end of the support column 2. A slide groove 31 is provided inside the support column 2. A screw rod 32 is provided inside the slide groove 31. A slider 33 is provided outside the screw rod 32.

[0029] The slide groove 31 is provided with an upper limit block 311 and a lower limit block 312 .

[0030] In this embodiment, the motor 30 drives the screw rod 32 to rotate, and the slider 33 located outside the screw rod 32 moves along the thread outside the screw rod 32 to adjust the height of the paper receiving platform 1. During the paper receiving process, the motor 30 drives the screw rod 32 to rotate, so that the slider 33 drives the paper receiving platform 1 to gradually rise to the highest position, ensuring that the paper can be neatly stacked on it without slipping or scattering.

[0031] When entering the printing stage, the height of the paper will become higher and higher, and the paper collection platform 1 will gradually descend under the drive of the lifting mechanism until the paper collection platform 1 descends to the lowest height. At this time, the printing has also reached the predetermined goal, so the whole system will automatically stop working and wait for the next start.

[0032] Based on the above embodiments, refer to Figure 3 A buffer mechanism 7 is provided between the slider 33 and the connecting block 10. The buffer mechanism 7 includes a mounting seat 70. A movable rod 71 is provided inside the mounting seat 70. A spring 72 is provided on the outer side of the movable rod 71. The upper end of the movable rod 71 is connected to the connecting block 10.

[0033] In this embodiment, during the paper collection process, the paper is continuously stacked on the tray, which increases the load-bearing capacity of the paper collection platform 1, causing the contact portion of the paper collection platform 1 and the slider 33 to be under stress for a long time, affecting the service life of the equipment. The spring 72 is used for buffering to reduce the load on the supporting connection position between the paper collection platform 1 and the slider 33 due to weight, thereby improving the service life.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
