[0002] In the current technology, when a rotary printing machine is working, usually only one roll of paper material can be placed. After one roll of paper is used up, the placing rod needs to be removed from the machine. After replacing it with a new paper roll, the placing rod is then installed on the machine again. Thus, during the process of replacing the paper roll, the machine needs to stop for a long time, which affects the working efficiency. Summary of the Utility Model

[0003] The purpose of this part is to outline some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this part, as well as in the abstract and the title of the utility model of this application, to avoid obscuring the purpose of this part, the abstract, and the title of the utility model. However, such simplifications or omissions cannot be used to limit the scope of the utility model.

[0004] In view of the following technical problems existing in the prior art: currently, a rotary printing machine can only store one paper roll during operation, resulting in a relatively long time consumption when replacing the used paper roll, thus affecting the overall printing efficiency of the equipment. To solve this technical problem, the utility model provides the following technical solutions:

[0022] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the following will describe in detail the specific implementation manners of the present utility model with reference to the accompanying drawings of the specification.

[0023] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar promotions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0024] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present utility model. The "in one embodiment" that appears in different places in this specification does not all refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0025] Furthermore, the present utility model is described in detail in conjunction with the schematic diagrams. When describing the embodiments of the present utility model in detail, for the convenience of explanation, the cross-sectional views showing the device structure will be enlarged locally out of the general proportion, and the schematic diagrams are only examples, and they should not limit the protection scope of the present utility model herein. In addition, in actual production, three-dimensional spatial dimensions including length, width and depth should be included.

[0026] Referring to Figures 1-3 , an embodiment of the present utility model provides a paper guiding mechanism for a rotary printing machine. Specifically, the mechanism has a first position and a second position, and one of the first position and the second position is the position where the placing rod 8 exists during the normal operation of the equipment. The present utility model further includes the following parts:

[0027] The support part 1, the number of which is at least two groups, and two support parts 1 are a group. The two groups of the support parts 1 are respectively located at the first position and the second position. The support part 1 is used for the overlapping of the end of the placing rod 8. Therefore, the mechanism can place a placing rod 8 at each of the first position and the second position at the same time, and this state is as shown in Figure 1 ;

[0028] The driving component 2, specifically regarding its function, the two sets of the supporting parts 1 can be simultaneously position-swapped through the driving component 2, that is, a pair of supporting parts 1 originally at the first position move to the second position, and a pair of supporting parts 1 originally at the second position move to the first position;

[0029] When the paper guiding mechanism provided by the present utility model works in cooperation with a printing machine, two paper rolls can be prepared simultaneously and respectively placed on two placing rods 8. The two placing rods 8 are respectively located at the first position and the second position through two sets of supporting parts 1. Now, assume that the first position is the normal position of the placing rod 8 when the equipment is working. When the paper roll on the placing rod 8 at the first position runs out, the two sets of supporting parts 1 are controlled by the driving component 2 to swap positions, so that the placing rod 8 loaded with the paper roll moves from the second position to the first position, and the end of the paper tape is connected to the equipment, thus completing the paper changing process, and the equipment continues to work. During this process, the downtime of the equipment is relatively short. At this time, the empty placing rod 8 moves to the second position, and then it can be taken down to replace the paper roll. After the paper roll at the current first position runs out, continue to change the paper according to the above process;

[0030] Compared with the prior art, during the process of cooperating with the printing work, the present utility model can replace the next paper roll in advance before the current paper roll runs out. Therefore, when changing the paper roll, only the two placing rods 8 need to be controlled to swap positions, so that the paper changing time is shorter and the working efficiency of the whole machine is higher.

[0031] Further, referring to Figure 1 and Figure 2 , regarding the provision of the first position and the second position, the present utility model further includes a circulating guide rail 3, the number of which is at least two and is symmetrically arranged. The supporting part 1 is movably arranged on the guide rail and can move along the direction of the circulating guide rail 3. Among the two sets of supporting parts 1, two supporting parts 1 in each group are respectively located on two circulating guide rails 3 and can move in the same direction through the driving component 2. The first position and the second position are two specific positions in the path of the circulating guide rail 3, such as the positions shown in the current Figure 1 . The width of the circulating guide rail 3 is greater than the maximum radius of the paper roll. Therefore, when the two supporting parts 1 move respectively, the empty placing rod 8 will not touch the paper roll.

[0032] Further, referring to Figures 1-4 , regarding the movable connection manner between the supporting part 1 and the circulating guide rail 3, two rollers 4 are rotatably arranged on the supporting part 1. The main path of the circulating guide rail 3 is a groove-like structure, specifically as Figure 5As shown, the roller 4 is located in its groove structure, thereby forming a rolling fit with the circulating guide rail 3. The cooperation of the two rollers 4 can fully maintain the stability of the support part 1 during the movement.

[0033] Further, see Figure 4 The support portion 1 includes a connecting block 101 and a bearing block 102, the roller 4 is arranged on the connecting block 101, one end of the bearing block 102 is rotatably matched with the connecting block 101, and an overlap portion 5 is arranged on the bearing block 102, and the overlap portion 5 is located at the center of gravity of the bearing block 102, and the rotational matching position of the bearing block 102 and the connecting block 101 is located at one end of the bearing block 102, so that the rotational matching position deviates from the center of gravity of the bearing block 102, so that the overlap portion 5 is always located below the rotational matching position through the pressure of the center of gravity to keep the direction of the bearing block 102 unchanged, that is, the direction of the overlap portion 5 unchanged, the overlap portion 5 is a notch-shaped structure, which is used to support the end of the stick 8. This structure ensures that when the connecting block 101 moves, the overlap portion 5 remains in the same direction, thereby facilitating manual picking up and placement of the stick 8.

[0034] Furthermore, Figure 5 This is a schematic diagram of a section of the path of the circulating guide rail 3, referring to Figure 1 , Figure 2 and Figure 5 The driving assembly 2 includes a driving wheel 201 that is arranged to rotate relative to the circulating guide rail 3, and a transmission belt 202 that is wound between the driving wheel 201 and the circulating guide rail 3. The transmission belt 202 can be a chain belt, in which case the driving wheel 201 is a sprocket structure. The transmission belt 202 can also be a chain, in which case the driving wheel 201 is a gear. The movement path of the transmission belt 202 is consistent with the path of the circulating guide rail 3, and on the support part 1, at least one roller 4 has an axle connected to the transmission belt 202, and the driving wheel 201 is configured with a corresponding rotating power. When the driving wheel 201 rotates, it drives the transmission belt 202 to move, thereby completing the pulling of the roller 4, and making the support part 1 move along the path of the circulating track, thereby completing the switching process of the two groups of support parts 1 at the first position and the second position.

[0035] Further, see Figure 1 and Figure 2 Regarding the configuration of the rotating power on the driving wheel 201, the utility model also includes a driving motor 6 fixedly arranged relative to the circulating guide rail 3. The driving motor 6 preferably adopts a servo motor, which is transmission-connected to the driving wheel 201. The servo motor can be directly fixed on the frame of the circulating guide rail 3. Through the cooperation of the servo motor, the movement amplitude of the transmission belt 202 can be accurately controlled.

[0036] Further, see Figure 1 and Figure 2, regarding the relative fixed setting between the two circulating guide rails 3, the present utility model further includes a connecting portion 7, the connecting portion 7 is fixedly connected to the two circulating guide rails 3, the connecting portion 7 can be a bracket structure, and it can be integrally connected to the two circulating guide rails 3. Through the action of the connecting portion 7, the stable effect between the two circulating guide rails 3 can be fully maintained. At the same time, when the entire paper guiding mechanism is installed on the printing machine, the connecting portion 7 can be connected to the printing machine, thereby further facilitating this process.

[0037] It should be understood that in the development process of any actual implementation, such as in any engineering or design project, a large number of specific implementation decisions can be made. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, without excessive experimentation, the development efforts will be a routine task of design, manufacturing, and production.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and not to limit them. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present utility model, and they should all be covered within the scope of the claims of the present utility model.
