Description

Technical Field

[0001] The utility model relates to the field of water-based ink printing machines, in particular to a leading-edge paper blocking mechanism for a high-speed water-based ink printing machine. Background Art

[0002] A high-speed water-based ink printing machine is a machine that uses water-based ink for high-speed printing. With its high-speed and high-precision printing capabilities, as well as the characteristics of using environmentally friendly water-based ink, the high-speed water-based ink printing machine plays an important role in the process of producing corrugated paper for packaging cartons. It can not only improve the printing efficiency, but also reduce the impact on the environment while ensuring the printing quality. The leading-edge paper blocking mechanism of the high-speed water-based ink printing machine is a key component in the printing machine, which is mainly responsible for stabilizing and controlling the position of the paper (or carton board) during the printing process to ensure the accuracy and quality of printing.

[0003] In the existing patent application with the application number CN202322364916.2, a leading-edge paper blocking mechanism for a high-speed water-based ink printing machine is proposed. When in use, the stacked carton boards are placed between the right baffle and the left baffle, and the right baffle and the left baffle are driven by a driving device to move closer to each other, so that the right baffle and the left baffle are respectively in contact with the left and right sides of the carton board. When the lowermost layer of the carton board is conveyed outwards, the height of the carton board continuously decreases. The right part of the carton board is guided and supported by the right baffle, and the left part of the carton board is guided and supported by the cooperation of the left baffle and the guide roller. Since the right end of the guide roller protrudes from the right side of the left baffle, the guide roller is used to roll-guide the carton board when it descends. Although the friction force when the carton board descends is reduced to a certain extent, the situation where the carton board is stuck between the right baffle and the left baffle is reduced, and the smoothness of the conveying is improved. However, the guide roller is only located at the upper part of the left baffle. When the carton board descends, the carton board will still contact the right baffle and the left baffle. Since the right baffle and the left baffle are fixed, the carton board will still be subject to the frictional resistance of the right baffle and the left baffle. Therefore, the carton board still has a high probability of being stuck between the right baffle and the left baffle. Therefore, the smoothness of the carton board conveying still needs to be further improved, so it needs to be improved. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a leading-edge paper blocking mechanism for a high-speed water-based ink printing machine, which can effectively solve the problems in the background art.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A leading-edge paper blocking mechanism for a high-speed water-based ink printing machine, including an equipment housing, on which an installation guide rod and a bidirectional lead screw are installed. Two paper blocking components are installed on the installation guide rod and the bidirectional lead screw. The paper blocking component is composed of a mounting plate, a connecting rod, a base plate and a mounting block. The connecting rod is fixedly installed at the front end of the mounting plate, the base plate is fixedly installed at the front end of the connecting rod, there are two mounting blocks which are symmetrically and fixedly installed at the upper and lower ends of the base plate. A resistance reducing component is rotatably installed on the base plate and the two mounting blocks. The resistance reducing component is composed of a rotating shaft, a supporting roller and a contact belt. There are two rotating shafts which are respectively rotatably installed on the two mounting blocks. There are four supporting rollers which are respectively fixedly installed at both ends of the two rotating shafts. The contact belt is sleeved on the four supporting rollers.

[0007] Preferably, a guide post is installed on the equipment housing, and a guide plate is installed on the guide post.

[0008] Preferably, the installation guide rod is located below the guide post, the bidirectional lead screw is located below the installation guide rod, and both the installation guide rod and the bidirectional lead screw are located behind the guide plate.

[0009] Preferably, threaded holes and installation holes are provided on the mounting plate of the paper blocking component. The mounting plate is installed on the bidirectional lead screw through the threaded holes, and the mounting plate is simultaneously installed on the installation guide rod through the installation holes. Installation grooves are provided on the mounting blocks.

[0010] Preferably, the rotating shaft of the resistance reducing component is rotatably installed in the installation holes provided on the mounting blocks.

[0011] Preferably, the contact belt is simultaneously sleeved on the base plate and the mounting blocks.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] By providing a paper blocking mechanism composed of a paper blocking component and a resistance reducing component, during use, the cardboard boxes stacked together can be placed between two groups of paper blocking mechanisms composed of a paper blocking component and a resistance reducing component. At this time, the paper blocking mechanism can play a role in limiting and guiding the stacked cardboard boxes. At the same time, as the lowermost cardboard box is conveyed, the upper cardboard boxes will descend under the influence of gravity. The descending cardboard boxes will drive the contact belt of the resistance reducing component to rotate under the action of friction. As the contact belt rotates, the rotating shaft and the supporting roller will also rotate. Therefore, the existence of the resistance reducing component can reduce the resistance of the cardboard box descending, and further reduce the probability of the cardboard box getting stuck between the two groups of paper blocking mechanisms, and finally further improve the smoothness of the cardboard box conveying.

[0019] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4As shown in the figure, a front-edge paper blocking mechanism for a high-speed water-based ink printing machine includes an equipment housing 1. An installation guide rod 2 and a bidirectional lead screw 3 are installed on the equipment housing 1. A guide post 6 is installed on the equipment housing 1, and a guide plate 7 is installed on the guide post 6. The installation guide rod 2 is located below the guide post 6, and the bidirectional lead screw 3 is located below the installation guide rod 2. Both the installation guide rod 2 and the bidirectional lead screw 3 are located behind the guide plate 7. Two paper blocking components 4 are installed on the installation guide rod 2 and the bidirectional lead screw 3. The paper blocking component 4 is composed of an installation plate 8, a connecting rod 9, a base plate 10, and an installation block 11. The connecting rod 9 is fixedly installed at the front end of the installation plate 8, the base plate 10 is fixedly installed at the front end of the connecting rod 9, there are two installation blocks 11 and they are symmetrically and fixedly installed at the upper and lower ends of the base plate 10. A resistance reduction component 5 is rotatably installed on the base plate 10 and the two installation blocks 11. The resistance reduction component 5 is composed of a rotating shaft 15, a support roller 16, and a contact belt 17. There are two rotating shafts 15 and they are respectively rotatably installed on the two installation blocks 11. There are four support rollers 16 and they are respectively fixedly installed at both ends of the two rotating shafts 15. The contact belt 17 is sleeved on the four support rollers 16. When in use, the stacked cardboard boxes can be placed between two paper blocking mechanisms composed of the paper blocking component 4 and the resistance reduction component 5. Then, the bidirectional lead screw 3 can be driven to rotate by a driving device connected to the bidirectional lead screw 3, so that the two paper blocking mechanisms approach each other. Finally, the paper blocking mechanisms will contact both ends of the stacked cardboard boxes, thereby limiting and guiding the cardboard boxes. At this time, the contact belt 17 on the resistance reduction component 5 will contact the cardboard boxes. Then, as the lowermost cardboard box is conveyed, the upper cardboard boxes will descend under the influence of gravity, and the descending cardboard boxes will drive the contact belt 17 on the resistance reduction component 5 to rotate under the action of friction. As the contact belt 17 rotates, the rotating shaft 15 and the support roller 16 will also rotate. Therefore, the presence of the resistance reduction component 5 can reduce the resistance of the cardboard boxes to descend, and further reduce the probability of the cardboard boxes being stuck between the two paper blocking mechanisms, and finally further improve the smoothness of the cardboard box conveying.

[0021] Furthermore, a threaded hole 13 and an installation hole 14 are provided on the installation plate 8 of the paper blocking component 4. The installation plate 8 is installed on the bidirectional lead screw 3 through the threaded hole 13, and the installation plate 8 is simultaneously installed on the installation guide rod 2 through the installation hole 14. An installation groove 12 is provided on the installation block 11. When the bidirectional lead screw 3 rotates, the paper blocking component 4 can move, that is, the two paper blocking components 4 will approach each other or move away from each other. When it is necessary to limit and guide the cardboard boxes, the two paper blocking components 4 can be made to approach each other. Conversely, the two paper blocking components 4 can be made to move away from each other.

[0022] Further, the rotating shaft 15 on the drag reduction component 5 is rotatably installed in the installation hole 14 formed in the installation block 11, and the contact belt 17 is sleeved on both the substrate 10 and the installation block 11 at the same time. When the cardboard box blocked by the paper blocking mechanism moves downward under the action of gravity, the contact belt 17 in contact with the cardboard box will be subjected to the frictional force of the downward movement of the cardboard box. Thus, under this frictional force, the contact belt 17 will rotate. At the same time, affected by the frictional force, the contact belt 17 will also drive the rotating shaft 15 and the support roller 16 to rotate. At this time, the rotating shaft 15 will rotate in the installation groove 12 formed in the installation block 11. Since the contact belt 17, the rotating shaft 15 and the support roller 16 can rotate, the resistance to the downward movement of the cardboard box will be smaller. Therefore, the probability that the cardboard box is stuck between the two paper blocking mechanisms will be smaller.
