[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, embossing, and paper feeding. Its working principle is: first, the text and image to be printed are made into a printing plate, which is then installed on the printing press. Then, the ink is applied to the places with text and images on the printing plate by humans or the printing press, and then directly or indirectly transferred to paper or other substrates, thereby replicating the same printed product as the printing plate. The invention and development of the printing press has played an important role in the spread of human civilization and culture.

[0003] The paper roller at the front end of the printing press is heavy. During the printing process, when the paper on the paper roller runs out and needs to be replaced, it is necessary to manually move the paper roller from the warehouse or use a vehicle to move the paper roller, and then install the paper roller on the paper roller rack at the front end of the printing press. This is time-consuming and labor-intensive, and the installation is difficult and time-consuming, which affects the working efficiency of the printing press. Utility Model Content

[0004] In view of the above-mentioned deficiencies, the utility model provides a paper roller storage mechanism that is easy to access. By installing the paper roller to the paper roller storage mechanism in advance, when replacing the paper roller of the printing press, it is only necessary to push the moving mechanism to the position to be replaced, replace the paper roller and the storage mechanism, and directly drag the paper from the paper pressing mechanism to quickly pull the end of the paper out of the paper roller, thereby improving the efficiency of paper roller replacement and thereby improving the working efficiency of the entire printing press.

The moving mechanism 2 includes two moving brackets 21, a crossbeam 22 connecting the two moving brackets 21 and a moving wheel 23 arranged at the bottom of the moving bracket 21, and the paper roll 1 is arranged between the two moving brackets 21 to facilitate the movement of the paper roll 1. The bearing mechanism 3 is installed on the moving bracket 21, and the bearing mechanism 3 includes a fixed plate 31, a fixed frame 32 and two bearing wheels 33, the fixed frame 32 is installed on the side wall of the moving bracket 21 through the fixed plate 31, and the bearing wheel 33 is installed on the fixed frame 32, there is a rotation gap between the two bearing wheels 33, and the two bearing wheels 33 have an upward bearing force on the paper roll shaft 11, so as to realize the bearing of the paper roll 1. The paper pressing mechanism 4 includes a fixed roller 41 and a paper pressing wheel 42. The fixed roller 41 is installed between the two movable brackets 21, and the paper pressing wheels 42 are located on both sides of the fixed roller 41. The paper pressing wheels 42 can elastically squeeze the paper 12 to the fixed roller 41, making it easy to pull out and fix the end of the paper 12 of the paper roller 1, thereby improving the efficiency of replacing the paper roller 1 of the printing press, thereby improving the working efficiency of the printing press.

[0028] In one embodiment, a plurality of storage mechanisms are provided in the paper roll 1 warehouse. Before use, the paper roll 1 is first installed on the supporting mechanism 3 of the storage mechanism, so that the two ends of the paper roll shaft 11 are erected by the supporting wheels 33. The arc-shaped cover plate 24 is plugged into the movable bracket 21 to achieve the squeezing and fixing of the paper roll 1. The end of the paper 12 is pulled out in advance, and the end of the paper 12 is abutted against the fixed roller 41 of the paper pressing mechanism 4, and the paper pressing wheel 42 is used to squeeze and fix the paper 12. When the printing press needs to replace the paper roll 1, the used paper roll 1 is moved to another position through the movable mechanism 2, and the new paper roll 1 is moved to the paper inlet of the printing press through the movable frame. The paper 12 between the fixed roller 41 and the paper pressing wheel 42 is directly pulled, and the paper 12 is installed in the paper inlet of the printing press. By directly pulling the paper 12 out between the fixed roller 41 and the pressure roller 42, the time required for tearing and arranging the end of the paper 12 on the paper roller 1 is saved, and the efficiency of disassembling and installing the paper 12 on the paper roller 1 to the printing press is improved.

[0029] Preferably, the fixed roller 41 is fixed to the movable bracket 21 through a bearing seat 43, and the paper pressing mechanism 4 also includes a fixed plate 31, a roller seat 45 and a tension spring 46; the fixed plate 31 is fixed to the crossbeam 22, and a strip sliding hole is opened on the fixed plate 31, and the paper pressing wheel 42 is installed on the roller seat 45, and the roller seat 45 and the fixed plate 31 are slidingly connected through the strip sliding hole. A tension spring 46 is also provided between the roller seat 45 and the fixed plate 31, and the tension spring 46 has an elastic force to pull the paper pressing wheel 42 close to the fixed roller 41, so as to press the end of the paper 12 to the fixed roller 41, so as to facilitate the installation of the paper 12 to the printing press.

[0030] In one embodiment, after the paper 12 is disassembled and pulled out from the paper roll 1, the pressing wheel 42 is manually pulled to move away from the fixed roll 41, so that an installation gap is formed between the fixed roll 41 and the pressing wheel 42, and the end of the paper 12 is abutted against the fixed roll 41 and placed between the fixed roll 41 and the pressing wheel 42. Then, the pulling of the pressing wheel 42 is released, and the pressing wheel 42 moves toward the fixed roll 41 under the action of the tension spring 46 until the pressing wheel 42 abuts against the paper 12, thereby fixing the end of the paper 12. This eliminates the process of unpacking the paper roll 1 from the original paper roll 1 and taking out the end of the paper 12 from the paper roll 1, thereby improving the efficiency of subsequently plugging the end of the paper 12 into the paper inlet of the printing press.

[0031] Preferably, the mobile mechanism 2 further comprises an arc-shaped cover plate 24, which can be plugged into the top of the mobile bracket 21, and both sides of the arc-shaped cover plate 24 and the mobile bracket 21 are provided with fixing ears 241, and bolt holes are provided on the fixing ears 241. By plugging the arc-shaped cover plate 24 into the mobile bracket 21, the paper roll 1 can be strengthened and fixed.

[0032] In one embodiment, after the paper roller 1 is mounted on two movable brackets 21, the arc cover plate 24 is covered on the top of the paper roller shaft 11, and fastening bolts are passed through the bolt holes of the two fixing ears 241 to achieve the installation and fixation of the arc cover plate 24 and the movable bracket 21. The arc cover plate 24 has a supporting and fixing effect on the paper roller shaft 11.

[0033] Preferably, the inner side of the arc cover plate 24 is coated with a Teflon coating, which has a low friction coefficient, so that the abutment between the paper roller shaft 11 and the arc cover plate 24 has a low friction coefficient. Under high load, the Teflon coating has excellent wear resistance, thereby ensuring the structural strength of the connection between the arc cover plate 24 and the paper roller shaft 11.

[0034] Preferably, the movable bracket 21 includes a horizontal plate 211 and a vertical plate 212. The vertical plate 212 is fixed to the middle position of the horizontal plate 211. A rib plate 213 is also connected between the vertical plate 212 and the horizontal plate 211. The rib plate 213 is provided to improve the connection strength between the horizontal plate 211 and the vertical plate 212, thereby improving the stability of the movable bracket 21 when supporting the paper roll 1.

[0035] Preferably, the fixing frame 32 is located on a side of the vertical plate 212 away from the cross beam 22 so as not to hinder the arc-shaped cover plate 24 from covering the top of the paper roller shaft 11 .

[0036] Preferably, a meter 25 is also installed on the movable bracket 21 , and the meter 25 is connected to the load-bearing wheel 33 . The meter 25 can calculate the rotation speed and operation time of the load-bearing wheel 33 , so as to calculate and detect the usage of the paper 12 on the paper roller 1 .

[0037] In one embodiment, the meter 25 can calculate the usage of the paper roller 1 according to the rotation speed and rotation time of the bearing wheel 33, so that the staff can read the usage of the paper 12. It should be noted that the meter 25 indirectly calculates the usage of the paper 12 through the data such as the rotation time, rotation speed and circumference of the bearing roller. The meter 25 belongs to the existing equipment, and the specific principle and structure of the meter 25 are not described in detail.

[0038] Preferably, the storage mechanism further includes a folding table 5, which is plugged into the mobile bracket 21. The folding table 5 has a folded state and an unfolded state. When the folding table 5 is in the folded state, the mobile bracket 21 can drive the folding table 5 to move; when the folding table 5 is in the unfolded state, part of the legs of the folding table 5 are in contact with the ground, and the folding table 5 has a limiting and fixing effect on the mobile bracket 21. Dragging the paper 12 above the folding table 5 helps to install the end of the paper 12 to the paper inlet of the printer.

[0039] In one embodiment, after the storage mechanism is moved to the paper inlet of the printing press, the folding table 5 can be unfolded to achieve preliminary fixation of the moving mechanism 2. The paper 12 between the fixed roller 41 and the pressure roller 42 is pulled out and spread on the surface of the folding table 5, which helps to connect the end of the paper 12 of the new paper roll 1 with the tail of the paper 12 of the old paper roll 1.

[0040] When the above-mentioned paper roller storage mechanism that is easy to access is adopted, by installing the paper roller 1 to the paper roller 1 storage mechanism in advance, when replacing the paper roller 1 of the printing press, it is only necessary to push the moving mechanism 2 to the position to be replaced, replace the paper roller 1 and the storage mechanism, and directly drag the paper 12 from the paper pressing mechanism 4 to quickly pull the end of the paper 12 out of the paper roller 1, thereby improving the efficiency of replacing the paper roller 1 and thereby improving the working efficiency of the entire printing press.
