Technical Field

[0001] The invention relates to the technical field of accounting, in particular to a bill punching machine for accounting. Background Art

[0002] As a relatively rigorous basic industry, the accounting industry needs to sort out bills, etc., which requires the corresponding bill punching machine to punch holes in the materials; For example, a bill punching machine with publication number CN208277030U belongs to the field of financial office supplies, and includes a machine body, a platform for placing bills arranged below the machine body, and a punching assembly arranged inside the machine body. A first push rod for driving the punching assembly to rise and fall to punch bills is fixedly arranged at the upper end of the punching assembly. In the provided bill punching machine, the first push rod is fixedly connected to the upper part of the inner cavity of the machine body, and the push rod part at the lower end of the first push rod is fixedly connected to the punching assembly. The punching assembly punches bills placed on the platform, making bill punching convenient. The first push rod drives the punching assembly to rise and fall, which can ensure the punching effect. Another example is a bill punching machine with publication number CN219294164U, which includes a punching table, the upper surface of which is provided with an ejector box, the outer surface of which is provided with a movable groove, the interior of which is movably connected to a connecting rod via a movable ring, the interior of which is movably connected to a cylinder box, the interior of which is provided with a cylinder, the top of which is movably connected to an ejector knife, the bottom of which is movably connected to an ejector, the outer surface of which is provided with a spring tube, and the upper surface of which is provided with a fixing clamp. It has the following advantages and effects: when in use, the ejector knife is pressed to cause the cylinder to generate air pressure to press down, driving the ejector to move downward to punch holes, and the ejector plays a reverse rebound role after the downward punching is completed through the spring tube, and the fixing clamp makes the material fixation effect better and prevents the punching position from being skewed; For example, a bill punching machine with publication number CN218518789U includes a punching device body, the inner cavity of the punching device body is fixedly connected to a hydraulic device, the bottom of the hydraulic device is fixedly connected to a movable plate, the bottom of the movable plate is provided with an adjustment slot, the inner cavity of the adjustment slot is provided with an adjustment block, the bottom of the adjustment block is provided with a punching tube, the front of the movable plate is provided with a fastening slot, and the inner cavity of the fastening slot is provided with a fastening knob. According to the number and spacing of holes to be punched, as well as the scale and the second scale, the left and right positions of the adjustment block in the adjustment slot are adjusted, and then the fastening knob in the fastening slot is rotated to fix the position of the adjustment block, that is, the position of the punching tube, and the hydraulic device is turned on so that the movable plate drives the punching tube to move downward to complete the punching of the bill, thereby achieving the purpose of accurately punching the bill; Most of the above-mentioned bill punching machines have improved their overall structure. However, during the operation of existing accounting bill punching machines, direct punching will produce a certain amount of punched residual paper pieces, most of which will stick to the material paper, requiring users to manually peel off and collect and clean them. It is impossible to stably collect the residual materials produced while punching and prevent residue, and thus there are certain limitations in use. Summary of the invention

[0005] Further, the auxiliary suction structure is provided with a connecting and docking punching rod, and the connecting and docking punching rod is fixedly connected to the lower end of the movable docking seat, and the connecting and docking punching rod is nested and docked with the fixed nesting piece, and a fitting piston piece is nested and installed on the inner side of the fixed nesting piece, and a second return spring is fixedly connected to the lower end of the fitting piston piece, and the upper end of the second return spring and the lower end of the fixed nesting piece are docked with each other; A first traction rope is fixed to the upper end of the fitting piston member, and the first traction rope passes through the interior of the fixed nesting member, and the upper end of the first traction rope is butted with the outer upper end of the movable butt joint seat.

[0006] Furthermore, the movable docking seat cooperates with the pressure of the reserved handle to slide vertically along the lower end of the vertical support seat, and the movable docking seat forms an elastic reset structure with the base through the first reset spring. The connecting docking punching rod synchronously penetrates and moves downward along the outer side of the fixed nested part as the movable docking seat moves downward.

[0007] Furthermore, during the downward movement of the connecting and docking punching rod and the movable docking seat, the first traction rope docked with the movable docking seat is synchronously subjected to force to drive the fitting piston part at the end to press the second return spring to move upward along the interior of the fixed nested part, and the outer side of the lower end of the fitting piston part and the inner wall of the connecting and docking punching rod are fitted together to form an active negative pressure state.

[0012] Furthermore, the second docking airbag pushes the docked second docking airbag to move downward synchronously during the process of being compressed and expanded, and the second docking airbag cooperates with the guiding docking piece to slide vertically along the upper end of the auxiliary centering piece.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The accounting bill punching machine is provided with an auxiliary suction structure. When the punching rod and the movable docking seat are connected and moved downward as the user applies pressure to the reserved handle 4, the first traction rope docked with the movable docking seat will be synchronously driven by the force to drive the fitting piston at the end to press the second return spring to move upward along the inside of the fixed nesting member to form an active negative pressure state, thereby adsorbing and collecting the debris generated by the punching. Furthermore, after the connected and docked punching rod is reset upward, the collected waste scraps can be quickly and evenly removed by the returning and downwardly moving fitting piston member, so as to avoid the residues on the surface of the material being unable to fall off. The quantitative punching residual paper scraps produced by direct punching are adsorbed and collected by the auxiliary suction structure, so as to avoid the residues from sticking to the material paper. The user does not need to perform subsequent manual peeling and collection and cleaning. The residual materials produced can be stably self-collected and treated to prevent residues while punching, thereby improving the practicality of the device. Furthermore, an auxiliary self-positioning structure is provided. When the movable docking seat is forced to move downward, the two sets of auxiliary centering parts docked with it through the second traction rope will be forced to slide inward toward each other along the surface of the base, thereby quickly assisting the position correction of the contacting material to avoid a skewed state.

[0014] Furthermore, during the process of the auxiliary centering piece being forced to move inward, its lower end will synchronously apply pressure to the first docking airbag in contact, and the first docking airbag with a transverse corrugated structure will transmit air supply to the second docking airbag through the air supply hose, so that the second docking airbag is pressurized and expanded, pushing the docking second docking airbag and the guide docking piece to slide vertically along the upper end of the auxiliary centering piece, thereby quickly pressing the lighter material in contact after centering, avoiding unstable positioning and improving the stability of punching.
