Description

Technical Field

[0001] The utility model belongs to the technical field of printing machines, and in particular relates to a paper discharging mechanism of a printing machine. Background Art

[0002] A modern printing press is 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 and installed on a printing press. Then, ink is applied to the places with text and images on the printing plate manually or by a printing press, and then directly or indirectly transferred to paper or other substrates, thereby replicating a printed product identical to the printing plate. The printed papers are then collected together to complete a complete printing process. The paper output mechanism is one of the most important structures in printing equipment, which is used to drive the discharge of printed paper.

[0003] The existing paper discharge mechanism discharges the paper directly to the ground or table, and then it is manually collected and sorted, and the printed products are transported to other places. Manually sorting and transporting the paper discharged from the paper discharge mechanism is time-consuming and labor-intensive, and inefficient. When the printing press is in continuous operation, the paper discharge mechanism continuously discharges paper. When the existing paper collection table and collection box reach the rated amount of paper, the printing press needs to be stopped to collect and empty the printed paper, and then the printing press can be started for printing, which reduces the working efficiency of the printing press. Utility Model Content

[0004] In view of the above-mentioned deficiencies, the utility model provides a paper discharge mechanism of a printing press, by installing a paper carrier and a shielding frame at the paper outlet of the printing press, so that the printed papers can be neatly stacked on top of the paper carrier. The sliding mechanism drives the loading platform to move in the vertical direction to realize the support of the loading platform on the paper carrier, so that the paper carrier can accommodate more printed papers. When transporting the paper, it is only necessary to use a forklift structure to replace the loading platform and the paper carrier, which is convenient for the transportation of the paper. A rotating support frame is provided to support the paper carrier, so that the paper can be temporarily collected when the loading platform is replaced, so that the printed paper can be transported without stopping the printing press, thereby ensuring the working efficiency of the printing press.

[0030] like Figures 1 to 5 The paper discharging mechanism of a printing press is shown. The printing press 1 conveys the printed paper from the paper outlet 12 to the outside through the paper discharging roller 11. The paper discharging mechanism includes a sliding mechanism 2, a loading platform 3, a rotating support frame 4 and a shielding frame 5. The sliding mechanism 2 includes a slide rail 21 and a sliding plate 22 mounted to the slide rail 21. The slide rail 21 is vertically mounted to the side wall of the printing press 1. The loading platform 3 is placed on the sliding plate 22. The loading platform 3 includes a loading plate 31 and a plurality of supporting columns 32. The rotating support frame 4 is installed on both sides of the paper outlet 12. A paper carrier 41 is inserted into the rotating support frame 4. The paper carrier 41 is used to carry the paper flowing out of the paper outlet 12. The shielding frame 5 is fixed to the paper outlet 12. The shielding frame 5 can guide the paper flowing out of the paper outlet 12 to fall to the paper carrier 41, which is convenient for collecting and sorting the paper, thereby improving the working efficiency of the printing press 1 and the efficiency of paper transportation.

[0031] In one embodiment, the stage 3 is first secured to the sliding plate 22, and the paper carrier 41 is placed on the surface of the stage 3. The control motor drives the sliding plate 22 to move upward in the vertical direction until the paper carrier 41 is located at the paper outlet 12 of the printing press 1. The printing press 1 is started, and the paper printed by the printing press 1 flows out of the paper outlet 12 under the action of the paper outlet roller 11. The paper falls onto the paper carrier 41 under the action of the shielding frame 5 and is stacked on the paper carrier 41. As the thickness of the paper above the paper carrier 41 increases, the control motor drives the sliding plate 22 to descend a set distance, and then waits for the paper above the paper carrier 41 to gradually thicken until the control motor drives the sliding plate 22 to move to the bottom of the slide rail 21.

[0032] When the thickness of the paper above the paper carrier 41 reaches the full-load thickness, the rotating support frame 4 is manually rotated until the extension direction of the support rod 43 is consistent with the paper output direction, and the new paper carrier 41 is quickly inserted into the slide groove 431 between the two support rods 43. At this time, the paper flowing out of the paper outlet 12 of the printing machine 1 is stacked on the new paper carrier 41. Then, a forklift or other mechanism is used to move the stage 3, the paper carrier 41 located above the stage 3, and the fully loaded paper out of the sliding plate 22 and transport them to the storage position. The new stage 3 is placed on the sliding plate 22, and the motor is controlled to drive the sliding plate 22 to move vertically upward until the table surface of the new stage 3 abuts against the bottom surface of the new paper carrier 41. The support rods 43 on both sides of the new paper carrier 41 are rotated in the direction away from the paper carrier 41 so that the new paper carrier 41 is separated from the support of the two support rods 43. Thus, the new loading platform 3 supports the paper carrier 41, and the motor is controlled to drive the sliding plate 22 to descend a set distance within a set time, so that the paper flowing out of the paper outlet 12 can be stacked on the paper carrier 41. The printing press 1 can quickly transfer the printed paper without stopping, thereby ensuring the printing efficiency of the printing press 1.

[0033] Preferably, the rotating support frame 4 includes a steering seat 42 installed on the side wall of the printing machine 1, a support rod 43 installed on the steering seat 42, and a rotating handle 44. The support rod 43 is provided with a slide groove 431 on the side facing the paper. The height of the slide groove 431 is greater than the thickness of the paper carrier 41. The paper carrier 41 can be inserted into the slide groove 431 to facilitate the transfer of paper on the loading platform 3.

[0034] In one embodiment, the rotating support frame 4 has a supporting state and a free state. When the rotating support frame 4 is in the supporting state, Figure 1 to Figure 2 As shown, the extension direction of the support rod 43 is consistent with the paper output direction, and the paper carrier 41 can be inserted into the slide groove 431 on the inner side of the two support rods 43; when the rotating support frame 4 is in a free state, the support rod 43 is separated from the area directly above the paper carrier 41 so as not to affect the downward movement of the paper carrier 41 driven by the loading platform 3.

[0035] Preferably, an anti-collision rubber is installed on one side of the support rod 43 close to the steering seat 42 to buffer the impact of the paper carrier 41 on the support rod 43 and protect the paper carrier 41 and the support rod 43.

[0036] Preferably, the surface of the slide groove 431 is coated with a Teflon coating. Teflon has a low friction coefficient and excellent wear resistance, so that the surface of the slide groove 431 has good sliding properties and wear resistance, thereby increasing the service life of the support rod 43.

[0037] Preferably, the rotating handle 44 is located on a side of the support rod 43 away from the paper, so as to facilitate the rotation and movement of the support rod 43 .

[0038] In one embodiment, a rotating handle 44 is provided to facilitate the rotation of the support rod 43 . The rotating handle 44 is located on a side of the support rod 43 away from the paper so as to reduce the obstruction of the rotating handle 44 on the paper falling onto the paper carrier 41 .

[0039] Preferably, an insertion space for a forklift to be inserted is formed between adjacent support columns 32, so as to facilitate the transportation and movement of the support platform.

[0040] Preferably, a cylindrical groove 221 is opened on the top of the sliding plate 22 , the diameter of the cylindrical groove 221 is larger than the diameter of the support column 32 , and the number of the cylindrical grooves 221 is consistent with the number of the support columns 32 , thereby improving the stability of the support platform placed on the sliding plate 22 .

[0041] Preferably, a base 6 is provided at the bottom of the printing machine 1, and an embedding groove 61 is provided on the base 6. The embedding groove 61 is located directly below the sliding plate 22. The embedding groove 61 cooperates with the sliding plate 22 to facilitate the movement of the support platform.

[0042] Preferably, a detector 51 is also installed on the shielding frame 5, and the detector 51 is connected to the printing machine 1 by signal to realize an early warning of full paper load.

[0043] In one embodiment, when the height of the paper stack reaches the set maximum height, the detector 51 sends an alarm signal and causes the control motor to drive the sliding plate 22 to move downward, so that the paper on the paper carrier 41 moves downward. When the control motor drives the sliding plate 22 to move downward to the bottom, the detector 51 sends an alarm and forces the printing machine 1 to suspend printing operations to ensure the safety of the printing operations.

[0044] Preferably, the sliding mechanism 2 further includes a control motor, which can control the moving direction and moving speed of the sliding plate 22 to provide power support for the sliding plate 22 to slide along the slide rail 21 .

[0045] When the above-mentioned paper discharge mechanism of a printing press is adopted, by installing a paper carrier 41 and a shielding frame 5 at the paper outlet 12 of the printing press 1, the printed paper can be neatly stacked on top of the paper carrier 41. The sliding mechanism 2 drives the stage 3 to move in the vertical direction to realize the support of the paper carrier 41 by the stage 3, so that the paper carrier 41 can accommodate more printed paper. When transporting paper, it is only necessary to use a forklift structure to replace the stage 3 and the paper carrier 41, which is convenient for transporting paper. A rotating support frame 4 is provided to support the paper carrier 41, so that the paper can be temporarily collected when the stage 3 is replaced, so that the printed paper can be transported without stopping the printing press 1, thereby ensuring the working efficiency of the printing press 1.
