Description

Technical Field

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

[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 (including folding). When a printing press is in use, the paper is easily offset when it is discharged, resulting in printing misalignment. It is necessary to limit and guide the printing paper. Therefore, a printing paper guide mechanism is needed. However, the current printing paper guide mechanism still has the following shortcomings:

[0003] For example, the patent document with application number 202221732251.5 discloses a printing paper guide mechanism for a printing press. The printing paper guide mechanism for a printing press adjusts the lifting frame to a suitable distance by rotating the threaded rod, thereby guiding the paper and adjusting the distance between the upper guide roller and the lower guide roller, but the paper replenishment process is relatively cumbersome, and it is inconvenient to replenish the printing paper in time.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a printing paper guiding mechanism is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a printing paper guiding mechanism to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a printing paper guiding mechanism, comprising a limiting main frame and a paper filling component, the limiting main frame is an integrally formed plastic structure, the paper filling component is arranged on the inner surface of the limiting main frame, and the paper filling component comprises a limiting slide bar, a magnetic snap-in groove, a metal snap-in plate, a limiting paper supply frame, an auxiliary pull-out plate and a limiting slide bar, the inner surface of the limiting main frame is provided with a limiting slide bar, and the rear surface of the inner side of the limiting main frame is provided with a magnetic snap-in groove, the inner side of the magnetic snap-in groove is snap-connected with a metal snap-in plate, and the front surface of the metal snap-in plate is installed with a limiting paper supply frame, the front surface of the limiting paper supply frame is provided with an auxiliary pull-out plate, and the surfaces on both sides of the limiting paper supply frame are provided with limiting slide bars.

[0007] Furthermore, the limiting slide bar and the limiting slide groove are arranged correspondingly, and the limiting slide bar and the limiting slide groove are slidably connected.

[0008] Furthermore, the interior of the limiting main body frame presents a central control structure, and a limiting groove is provided on the upper surface of the limiting main body frame.

[0009] Furthermore, a return spring is connected to the lower surface of the limiting groove, and a movable support rod is connected to the upper end of the return spring.

[0010] Furthermore, the movable support rod is slidably connected to the limiting groove, and a connecting rod is installed on the top of the left end of the movable support rod.

[0011] Furthermore, a fixing ring is installed on the top of the right end of the movable support rod, and a rotating motor is arranged on the inner surface of the fixing ring.

[0012] Furthermore, the output end of the rotating motor is connected to a guide roller via a coupling, and the left side of the guide roller is rotationally connected to the right end of the connecting rod.

[0013] Furthermore, a moving groove is provided on the inner upper surface of the position-limiting paper feeding frame, and a moving member is slidably connected to the inner side of the moving groove, and an adjustment frame is provided on the upper surface of the moving member.

[0014] The utility model provides a printing paper guide mechanism, which has the following beneficial effects:

[0015] 1. The utility model provides a paper-filling assembly, which includes a limit slide bar, a magnetic snap-in groove, a metal snap-in disk, a limit paper feed frame, an auxiliary pull-out plate and a limit slide bar. When in use, the limit paper feed frame can be pulled forward from the inner side of the limit main frame through the auxiliary pull-out plate, so that the limit paper feed frame slides outward along the limit slide bar through the limit slide bar. After the limit paper feed frame is filled with paper, the limit paper feed frame is pushed back, so that the limit paper feed frame slides inward along the limit slide bar through the limit slide bar until the metal snap-in disk is snap-connected with the magnetic snap-in groove. Due to the magnetic attraction of the magnetic snap-in groove and the metal snap-in disk, the limit paper feed frame is fixed to the limit main frame more firmly and is not easy to slip off, so that the device can conveniently and quickly replenish printing paper.

[0016] 2. The utility model is provided with a limit groove, a return spring, a movable support rod, a connecting rod, a fixed ring, a rotating motor and a guide roller. When in use, when the limit paper feeding frame is full of paper, the guide roller is squeezed by the printing paper, driving the connecting rod and the fixed ring to move upward, and further driving the movable support rod to slide upward along the inner side of the limit groove through the connecting rod and the fixed ring. At this time, the return spring is stretched by force, and the rotating motor is started, so that the rotating motor drives the guide roller to rotate around the right end of the connecting rod, thereby driving the paper out. In the process of reducing the paper, the squeezing force of the paper on the guide roller becomes smaller and smaller, and the return spring slowly rebounds, so that the guide roller can always keep in contact with the printing paper, so that the device can keep the printing paper fixed to avoid its deviation, and the device can realize automatic discharging.

[0021] The following is a further detailed description of the implementation of the present utility model in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0022] like Figures 1 to 3 As shown, a printing paper guiding mechanism includes a limiting main frame 1 and a paper filling component 2, the limiting main frame 1 is an integrally formed plastic structure, the paper filling component 2 is arranged on the inner surface of the limiting main frame 1, and the paper filling component 2 includes a limiting slide 201, a magnetic snap-in groove 202, a metal snap-in plate 203, a limiting paper supply frame 204, an auxiliary pull-out plate 205 and a limiting slide 206, the inner surface of the limiting main frame 1 is provided with a limiting slide 201, and the rear surface of the inner side of the limiting main frame 1 is provided with a magnetic snap-in groove 202, the inner side of the magnetic snap-in groove 202 is snap-connected with a metal snap-in plate 203, and the front surface of the metal snap-in plate 203 is installed with a limiting paper supply frame 204, the front surface of the limiting paper supply frame 204 is provided with an auxiliary pull-out plate 205, and the surfaces on both sides of the limiting paper supply frame 204 are provided with limiting slides 206.

[0023] The specific operation is as follows. When in use, the limit paper supply frame 204 can be pulled forward from the inner side of the limit main frame 1 through the auxiliary pull-out plate 205, so that the limit paper supply frame 204 slides outward along the limit slide bar 201 through the limit slide groove 206. After the limit paper supply frame 204 is replenished with paper, the limit paper supply frame 204 is pushed back, so that the limit paper supply frame 204 slides inward along the limit slide bar 201 through the limit slide groove 206 until the metal snap-in plate 203 is snap-connected with the magnetic snap-in groove 202. Due to the magnetic attraction of the magnetic snap-in groove 202 and the metal snap-in plate 203, the fixation of the limit paper supply frame 204 and the limit main frame 1 is relatively firm and not easy to slip off.

[0024] Please refer to Figure 2The interior of the limit main frame 1 is a central control structure, and the upper surface of the limit main frame 1 is provided with a limit slot 3, the lower surface of the limit slot 3 is connected with a return spring 4, and the upper end of the return spring 4 is connected with a movable support rod 5, the movable support rod 5 is slidably connected with the limit slot 3, and a connecting rod 6 is installed on the top of the left end of the movable support rod 5, a fixing ring 7 is installed on the top of the right end of the movable support rod 5, and a rotating motor 8 is arranged on the inner surface of the fixing ring 7, the output end of the rotating motor 8 is connected with a guide roller 9 through a coupling, and the left side of the guide roller 9 is rotatably connected with the right end of the connecting rod 6;

[0025] The specific operation is as follows. During use, when the limited paper supply frame 204 is full of paper, the guide roller 9 is squeezed by the printed paper, driving the connecting rod 6 and the fixed ring 7 to move upward, and further driving the movable support rod 5 to slide upward along the inner side of the limiting groove 3 through the connecting rod 6 and the fixed ring 7. At this time, the return spring 4 is stretched by the force, and the rotating motor 8 is started, so that the rotating motor 8 drives the guide roller 9 to rotate around the right end of the connecting rod 6, and then drives the paper out. In the process of reducing the paper, the squeezing force of the paper on the guide roller 9 becomes smaller and smaller, and the return spring 4 slowly rebounds, so that the guide roller 9 can always keep in contact with the printed paper.

[0026] Please refer to Figures 2 to 3 The limiting slide bar 201 is correspondingly arranged with the limiting slide groove 206, and the limiting slide bar 201 is slidably connected with the limiting slide groove 206. A moving groove 10 is provided on the inner upper surface of the limiting paper feeding frame 204, and a moving member 11 is slidably connected inside the moving groove 10, and an adjustment frame 12 is provided on the upper surface of the moving member 11;

[0027] The specific operation is as follows: when in use, according to the size of the printed paper, the adjustment frame 12 is pushed inward, so that the adjustment frame 12 slides along the inner side of the limiting slide groove 206 through the moving part 11 until the inner surface of the adjustment frame 12 fits with both sides of the paper, so as to further limit the paper.

[0028] In summary, if Figures 1 to 3As shown, when the printing paper guiding mechanism is used, first, the limited paper supply frame 204 can be pulled forward from the inner side of the limited main frame 1 through the auxiliary pull-out plate 205, so that the limited paper supply frame 204 slides outward along the limited slide bar 201 through the limited slide groove 206. After the limited paper supply frame 204 is filled with paper, the adjustment frame 12 is pushed inward according to the size of the printing paper, so that the adjustment frame 12 slides along the inner side of the limited slide groove 206 through the moving member 11 until the inner surface of the adjustment frame 12 is in contact with both sides of the paper, so as to further limit the paper. Subsequently, the limited paper supply frame 204 is pushed back, so that the limited paper supply frame 204 slides inward along the limited slide bar 201 through the limited slide groove 206 until the metal clamping plate 203 is clamped with the magnetic clamping groove 202. The limit paper feeding frame 204 is connected with the limit main body frame 1 by the magnetic attraction of the magnetic card slot 202 and the metal card slot disk 203. The fixation of the limit paper feeding frame 204 and the limit main body frame 1 is relatively stable and not easy to slip. When the limit paper feeding frame 204 is full of paper, the guide roller 9 is squeezed by the printing paper, driving the connecting rod 6 and the fixing ring 7 to move upward, and further driving the movable support rod 5 to slide upward along the inner side of the limit slot 3 through the connecting rod 6 and the fixing ring 7. At this time, the return spring 4 is stretched by force, and the rotating motor 8 is started, so that the rotating motor 8 drives the guide roller 9 to rotate around the right end of the connecting rod 6, and then drives the paper out. In the process of reducing the paper, the squeezing force of the paper on the guide roller 9 becomes smaller and smaller, and the return spring 4 slowly rebounds, so that the guide roller 9 can always keep in contact with the printing paper.
