Description

Technical Field

[0001] This application relates to the field of paper-aligning mechanism technology, and more specifically, to a flexible paper-aligning mechanism. Background Technology

[0002] Currently, after the printing of banknotes is completed, they need to be cut in units of "hundreds." The cutting process requires accurate edge positioning and alignment of these hundred sheets, necessitating an efficient and accurate paper alignment machine. Existing paper alignment machines all use an inclined vibrating worktable with an air blowing mechanism, relying on gravity and baffles in two directions to align the papers. This structure has some unreliable alignment factors; that is, at some point before the vibration ends, the paper may detach from the stack due to impact with the right or rear baffle. Existing paper alignment machines are not very efficient. To minimize these unreliable factors, the machine needs to vibrate for a relatively long time, leaving time for the papers to align after the vibration ends, resulting in low efficiency. Summary of the Invention

[0003] This application aims to solve at least one of the aforementioned technical problems.

[0004] Therefore, the primary objective of this application is to provide a flexible paper-aligning mechanism.

[0005] To achieve the first objective of this application, the first aspect of the present invention provides a flexible paper alignment mechanism, comprising: a frame; a vibration table disposed on the frame for placing paper cutters, the vibration table having a plurality of air blowing holes and a groove; a first baffle disposed on the vibration table; a second baffle disposed on the vibration table and perpendicular to the extending direction of the first baffle; an air blowing mechanism disposed on the vibration table for blowing air onto the paper cutters; and a flexible paper alignment push rod connected to the vibration table, the flexible paper alignment push rod including an elastic element, the elastic element being movably disposed in the groove for pressing and aligning the paper cutters.

[0006] In this technical solution, the flexible paper alignment mechanism includes a frame, a vibrating table, a first baffle, a second baffle, an air blowing mechanism, and a flexible paper alignment push rod. The flexible paper alignment push rod includes an elastic element. Specifically, the vibrating table surface has four grooves, and the elastic element within these grooves can move along the groove direction, aligning the paper cutters during its movement. During operation, the paper cutters tilt backward along with the table surface. At this time, the first and second baffles jointly restrict the paper's two degrees of freedom, serving as two reference surfaces for paper alignment. The air blowing mechanism blows air into the paper to separate it, preventing misalignment due to ink adhesion. The vibrating table has numerous small air holes that can blow the paper away from the vibrating table, reducing friction between the paper and the table, allowing the paper to automatically align towards the first and second baffles under gravity. Simultaneously, the vibrating table vibrates at a certain frequency, further aligning the paper. By adding constraints on two degrees of freedom through the elastic element, the paper is constrained within a fixed space, preventing it from popping out due to vibration and collision. The introduction of elastic elements allows for excellent control of the paper alignment force, automatically adjusting the force according to different paper sizes. This results in a good paper alignment effect while preventing paper wrinkling and deformation caused by excessive force. Flexible paper alignment push rods can shorten the running time of the paper alignment mechanism, effectively improving its operating efficiency.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0038] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0039] The following reference Figures 1 to 3 This application describes a flexible paper-aligning mechanism according to some embodiments.

[0040] like Figure 1 and Figure 2 As shown, an embodiment of the first aspect of the present invention provides a flexible paper-aligning mechanism 10, comprising: a frame 110; a vibration table 120 disposed on the frame 110 for placing paper clips, the vibration table 120 having a plurality of air-blowing holes and grooves; a first baffle 130 disposed on the vibration table 120; a second baffle 140 disposed on the vibration table 120 and perpendicular to the extending direction of the first baffle 130; an air-blowing mechanism 150 disposed on the vibration table 120 for blowing air onto the paper clips; and a flexible paper-aligning push rod 160 connected to the vibration table 120, which is flexible. The paper-aligning push rod 160 includes: a spring rod 162, which is movably disposed and cooperates with a groove, and the spring rod 162 can move in the groove along the groove direction; a cylinder 164, which is connected to the vibration table 120 and is used to push the spring rod 162 to move; a track 168, the height of the track 168 being inconsistent; a spring rod base 170, which is connected to the bottom of the spring rod 162 and slidably connected to the track 168; and a slide rod 172, which is telescopically disposed, one end of the slide rod 172 being connected to the cylinder 164, and the other end of the slide rod 172 being connected to the spring rod base 170.

[0041] In this embodiment, the flexible paper-aligning mechanism 10 includes a frame 110, a vibrating table 120, a first baffle 130, a second baffle 140, an air blowing mechanism 150, and a flexible paper-aligning push rod 160. The flexible paper-aligning push rod 160 includes a spring rod 162, a cylinder 164, a track 168, a spring rod base 170, and a slide rod 172. Specifically, the vibrating table 120 has four grooves on its surface, and the spring rod 162 can move along the groove direction, aligning the paper pieces during its movement. During operation, the paper feeder tilts backward along with the table surface. At this time, the first baffle 130 and the second baffle 140 restrict the paper's freedom in two directions, serving as two reference surfaces for paper alignment. The air blowing mechanism 150 blows air into the paper to separate it, preventing misalignment due to ink adhesion. The vibrating table 120 has many small air holes that can blow the paper away from the vibrating table 120, reducing friction between the paper and the vibrating table 120. This allows the paper to automatically align with the first baffle 130 and the second baffle 140 under gravity. Simultaneously, the vibrating table 120 vibrates at a certain frequency, further aligning the paper. The cylinder 164 provides the necessary thrust to the flexible paper alignment push rod 160. The spring rod 162 can elastically deform along the direction of cylinder 164's extension, allowing the thrust of cylinder 164 to be adjusted through elastic deformation to simulate the gentle pushing action of a human hand. The spring rod base 170 can slide along the track 168 when the cylinder 164 extends or retracts, achieving a lifting and lowering effect. Simultaneously, the spring rod base 170 can slide up and down along the slide rod 172. The spring rod 162 adds two degrees of freedom to constrain the paper within a fixed space, preventing it from popping out due to vibration or collision. The introduction of the spring rod 162 effectively controls the paper alignment force, automatically adjusting it according to different paper sizes, resulting in excellent paper alignment while preventing excessive force from causing paper wrinkling or deformation. The introduction of the flexible paper alignment push rod 160 shortens the operating time of the paper alignment mechanism, effectively improving its operating efficiency.

[0042] In the above embodiments, optionally, the trench includes two first trenches and two second trenches, the extension directions of the first trenches and the second trenches are perpendicular to each other, the two first trenches are spaced apart, and the two second trenches are spaced apart.

[0043] In the above embodiments, optionally, the first baffle 130 is arranged parallel to the first groove. The second baffle 140 is arranged parallel to the second groove.

[0044] In the above embodiments, optionally, the spring rod 162 includes a first spring rod and a second spring rod. The first spring rod is inserted into two first grooves, and the second spring rod is inserted into two second grooves, thereby aligning the paper. By adding two degrees of freedom of constraint through the spring rod 162, the paper is constrained within a fixed space, preventing the paper from popping out due to vibration or collision.

[0045] In the above embodiments, optionally, the cylinder 164 includes a first cylinder and a second cylinder, the first cylinder being used to push the first spring rod to slide in the first groove, and the second cylinder being used to push the second spring rod to slide in the second groove.

[0046] In the above embodiments, optionally, the spring rod base 170 includes a first base and a second base, the first base being connected to the bottom of the first spring rod, and the second base being connected to the bottom of the second spring rod.

[0047] In the above embodiments, optionally, the track 168 includes a first track and a second track, with the first base sliding on the first track and the second base sliding on the second track.

[0048] In the above embodiments, optionally, the slide bar 172 includes a first slide bar and a second slide bar, the first slide bar connecting the first cylinder and the first base, and the second slide bar connecting the second cylinder and the second base.

[0049] In the above embodiment, optionally, the piston diameter of cylinder 164 is 10mm, and it can provide a thrust of 62.8N under a pressure of 8bar.

[0050] like Figures 1 to 3 As shown, according to a specific embodiment of the flexible paper alignment mechanism 10 proposed in this application, during the paper alignment process, the flexible paper alignment push rod 160 is used to limit the paper stack, which can complete the paper alignment action more quickly. The intervention of the elastic material can effectively control the paper alignment force, that is, it will not damage the folded paper, and it can also imitate the process of human hand patting, helping the paper stack to be aligned quickly and accurately.

[0051] like Figure 3As shown, specifically, the flexible paper-aligning mechanism 10 includes a frame 110, a vibrating table 120, an air blowing mechanism 150, a flexible paper-aligning push rod 160, a first baffle 130, and a second baffle 140. The table surface of the vibrating table 120 has four grooves, and a spring rod 162 in each groove can move along the groove direction. During the movement of the spring rod 162, the paper pieces can be aligned. During operation, the paper will tilt backward along with the table. At this time, the first baffle 130 and the second baffle 140 restrict the paper's freedom in two directions, serving as two reference surfaces for paper alignment. The air blowing mechanism 150 blows air into the paper to separate it, preventing misalignment due to ink adhesion. The vibrating table 120 has many small air blowing holes, which can blow the paper away from the vibrating table 120, reducing the friction between the paper and the vibrating table 120. This allows the paper to automatically align with the first baffle 130 and the second baffle 140 under the action of gravity. At the same time, the vibrating table 120 vibrates at a certain frequency, further aligning the paper.

[0052] The flexible paper-aligning pusher 160 includes a spring rod 162, a cylinder 164, a track 168, a spring rod base 170, and a slide rod 172. The cylinder 164 primarily provides the thrust required by the paper-aligning mechanism. Its piston area is small, with a piston diameter of only 10mm. Under 8 bar pressure, it can provide a thrust of 62.8N. However, since the thrust of the cylinder 164 is only proportional to the compressed air pressure, and the compressed air pressure in the production workshop is difficult to adjust flexibly, the thrust is not adjustable. Therefore, the spring rod 162 is introduced. The spring rod 162 can elastically deform along the extension direction of the cylinder 164, allowing the thrust of the cylinder 164 to be adjusted through elastic deformation, thus simulating the gentle paper-aligning action of a human hand. The spring rod base 170 can slide along the track 168 when the cylinder 164 is extended or retracted, achieving a lifting and lowering effect. Simultaneously, the spring rod base 170 can slide up and down along the slide rod 172 while moving up and down along the track 168.

[0053] This embodiment uses a spring rod 162 to add two degrees of freedom to constrain the paper within a fixed space, preventing the paper from popping out due to vibration or collision. The introduction of the spring rod 162 can effectively control the paper alignment force, automatically adjusting the alignment force according to different paper sizes, thus achieving a good paper alignment effect while avoiding paper wrinkling and deformation caused by excessive alignment force. The introduction of the flexible paper alignment push rod 160 can shorten the running time of the paper alignment mechanism and effectively improve the operating efficiency of the paper alignment mechanism.
