Punching and hot riveting type precise binding machine

Abstract

The invention relates to a punching and hot riveting type precise binding machine. The machine comprises a punching unit and a hot riveting unit, which are arranged on a base in parallel, wherein the punching unit comprises a punching fixed base, a cover plate, a handle, a punching slider, a drill, paper pressing devices and a pipe cutting device; the drill and the paper pressing devices are arranged on the lower part of the punching slider; a rotating shaft horizontally penetrates through the punching fixed base; the handle is fixedly connected with the rotating shaft; gears are arranged at the two sides of the rotating shaft in the punching fixed base; guide rails are arranged at the two sides of the punching fixed base; the punching slider is joined between the two guide rails; vertical racks are arranged at the inner sides of the punching slider and are meshed with the gears; a bulk cavity is arranged in the middle of the punching slider; the cover plate is fixedly arranged on the upper part of the punching fixed base; and a reset tension spring is arranged between the bulk cavity and the cover plate. The machine has the advantages of simple and reasonable structure, balanced and stable driving, high accuracy and low cost.

Description

technical field [0001] The invention relates to a binding machine for binding office financial documents, in particular to a punching hot riveting precision binding machine. Background technique [0002] The transmission mechanism of the traditional punching hot riveting binding machine is generally a self-resetting guide post set at the geometric center of the frame. The self-resetting guide post has a tooth mouth that is matched with the single gear. The meshed gears move the guide column downwards, handles are required on both sides of the frame to balance the transmission of the gears, and a guide rod is provided on the paper pressing mechanism under the self-resetting guide column, and the self-resetting guide column is single-gear meshed Excessive wear and tear will easily cause the teeth gap to be uneven, so that the force on both sides of the guide rod of the paper pressing mechanism will be unbalanced, so that the pressing board cannot be positioned accurately, whic...

[0003] Moreover, the gear on the transmission mechanism of the traditional punching and binding machine generally does not have a corresponding positioning device. When the force is too large, the drill will directly drill into the rubber pad, causing damage to the drill and the pad, so that the bottom cannot be guaranteed. The last piece of paper can be effectively pierced
