Description

Technical Field

[0001] This utility model relates to the field of paper receiving mechanism technology, specifically a paper receiving mechanism for a printing press. Background Technology

[0002] A printing press is a machine for printing text and images. Modern printing presses generally consist of mechanisms such as plate mounting, inking, printing, and paper feeding. Its working principle is to first make a printing plate containing the text and images to be printed, mount it on the printing press, and then apply ink to the areas with text and images on the printing plate manually or by the printing press. The ink is then directly or indirectly transferred to paper or other printing substrates to reproduce printed products identical to the printing plate. The printed substrates need to be collected and stored.

[0003] To facilitate the collection of printed paper, existing technologies have made numerous improvements to the paper collection mechanism of printing presses. For example, patent publication number CN216140971U discloses a paper collection mechanism for a printing press. The base has a sliding groove, a first side plate is fixedly connected to the base, a fixed plate is fixedly connected to the first side plate, a motor is fixedly connected to the fixed plate, one end of the rotating drum passes through the first side plate and is fixedly connected to the output end of the motor, and is rotatably connected to the first side plate. A first limiting ring is fixedly connected to the rotating drum and sleeved on the outer wall of the rotating drum. A second limiting ring has a first through hole and is sleeved on the outer wall of the rotating drum. A fixed post is threadedly connected to the second limiting ring, a slider is slidably connected to the base, and the slider is fixed to the second side plate by two hinges. The second side plate has a second through hole. This structure allows for the collection of paper of various lengths and sizes, facilitates paper core replacement, accelerates production efficiency, and reduces the operational difficulty for employees.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0005] The aforementioned comparative document describes a paper receiving operation performed using a first limiting ring, a second limiting ring, and a rotatable drum. However, in actual operation, the paper roll is a relatively large circular shape after receiving, and its weight is considerable. This requires the use of lifting equipment to hoist and move the paper roll, making the operation cumbersome and reducing the efficiency of paper receiving. Therefore, there is an urgent need in the field to improve the paper receiving mechanism of printing presses to overcome the shortcomings of the prior art. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Example 1

[0029] Please see Figures 1-6 A paper receiving mechanism for a printing press includes a support base 1. A fixed support plate 2 is fixedly connected to the upper surface of the support base 1. A movable support plate 3, adapted to the fixed support plate 2, is slidably connected to the upper surface of the support base 1. A polygonal cross-section insertion shaft 4 is rotatably connected to one side of the upper end of the fixed support plate 2. A rotating shaft 5, inserted into the movable support plate 3, is fixedly connected to the end of the insertion shaft 4 away from the fixed support plate 2. A paper receiving shaft 6 is sleeved on the side of the insertion shaft 4. A first drive motor 7 for driving the insertion shaft 4 to rotate is fixedly installed on one side of the fixed support plate 2. A drive unit 8 for driving the movable support plate 3 to move is provided at one end of the support base 1. A lifting unit 9 for lifting the paper roll is also provided on the support base 1. When the drive unit 8 drives the movable support plate 3 to move, the lifting unit 9 moves accordingly. The drive unit 8 includes a second drive motor fixedly installed at one end of the support base 1. 13. A sliding block 10 is fixedly installed at the lower end of the movable support plate 3. A sliding groove 11 adapted to the sliding block 10 is opened on the upper surface of the support base 1. A drive screw 12 with one end fixedly connected to the output end of the second drive motor 13 is rotatably connected in the sliding groove 11. The drive screw 12 passes through the sliding block 10 and is threadedly connected to it. Mounting plates 24 for installation are fixedly connected to the opposite sides of the support base 1. The lifting unit 9 includes a movable seat 14 slidably connected in the sliding groove 11. An electric telescopic rod 15 is fixedly installed on the upper side of the movable seat 14. A bracket 16 adapted to the paper roll is fixedly installed at the upper end of the telescopic rod 15. A first adjusting bolt 17 is threadedly connected through one side of the movable support plate 3. One end of the first adjusting bolt 17 is rotatably connected to one side of the movable seat 14. A first limiting nut 18 for limiting is threadedly connected to the side of the first adjusting bolt 17.

[0030] In this specific implementation method: When paper needs to be wound up, firstly, the second drive motor 13 is started. The output end of the second drive motor 13 drives the drive screw 12 to rotate. When the drive screw 12 rotates, it drives the sliding block 10 to slide in the sliding groove 11. When the sliding block 10 moves, it drives the movable bearing plate 3 to slide on the upper surface of the bearing base 1. The rotating shaft 5 is disengaged from the movable bearing plate 3. The paper take-up shaft 6 is inserted into the side of the insertion shaft 4. The second drive motor 13 is started in reverse. The movable bearing plate 3 is sleeved on the side of the rotating shaft 5. The first drive motor 7 is started. The output end of the first drive motor 7 drives the insertion shaft 4 to rotate. The insertion shaft 4 drives the paper take-up shaft 6 to rotate, thus winding up the paper. When the paper roll is finished winding up, the electric telescopic rod 15 is started. The telescopic end of the electric telescopic rod 15 drives the bracket 16 to rise. The bracket 16 lifts the wound paper roll. At this time, the second drive motor 13 is started again. The drive motor 13 and the second drive motor 13 drive the movable support plate 3 to move again. While the movable support plate 3 moves, the first adjusting bolt 17 drives the moving seat 14 to move in the sliding groove 11, which in turn drives the bracket 16 to move, and drives the paper roll and take-up shaft 6 to move until the take-up shaft 6 disengages from the insertion shaft 4. Then the paper roll can be directly transferred by the transfer device, which is convenient for the transfer of the paper roll after the printing press has finished taking the paper. At the same time, the position of the bracket 16 can be adjusted by rotating the first adjusting bolt 17 to adjust the position of the bracket 16 to the middle position of the paper roll, so as to prevent the two ends of the bracket 16 from being unbalanced when lifting the paper roll. It is also suitable for taking the paper roll of different widths. After the position of the bracket 16 is adjusted, the first limit nut 18 is tightened to limit the position of the first adjusting bolt 17. The mounting plate 24 is provided with mounting holes, and the support base 1 is installed and fixed by the mounting plate 24.

[0031] All of the electrical products mentioned above can be purchased from the market. They are mature technologies and have been fully disclosed, so they will not be repeated in the instruction manual. All of the electrical products mentioned above are equipped with power cords, and they are electrically connected to the external main controller and 220V phase voltage (or 380V line voltage) through the power cords. The main controller can be a conventional known device such as a computer that plays a control role.

[0032] Example 2

[0033] Please see Figure 2 , Figure 4 and Figure 6This embodiment includes the above embodiment, and further includes: a limiting ring 19 for limiting the paper take-up shaft 6 is sleeved on the side of the insertion shaft 4; a second adjusting bolt 22 for adjusting the position of the limiting ring 19 is provided on the movable bearing plate 3; a rotating groove 20 is opened on one side of the limiting ring 19; a rotating ring 21 is rotatably connected in the rotating groove 20; one end of the second adjusting bolt 22 is rotatably connected to the side of the rotating ring 21; and a second limiting nut 23 for limiting is threadedly connected to the side of the second adjusting bolt 22.

[0034] In this embodiment, the following is a detailed implementation: After the take-up shaft 6 is installed, the limiting ring 19 abuts against one end of the take-up shaft 6 to limit the position of the take-up shaft 6. At the same time, the position of the limiting ring 19 can be adjusted by rotating the second adjusting bolt 22. When the insertion shaft 4 rotates, the limiting ring 19 rotates accordingly. At this time, the rotating groove 20 rotates along the rotating ring 21 without affecting the limiting ring 19's limitation on the take-up shaft 6. After the position of the limiting ring 19 is adjusted, the second limiting nut 23 is tightened to limit and fix the position of the second adjusting bolt 22, which facilitates the limitation of take-up shafts 6 of different lengths, and thus can be applied to take-up of paper of different widths.
