Description

Winding device of digital printing machine

Technical Field

The utility model relates to the technical field of digital printing machines, in particular to a winding device of a digital printing machine.

Background

Digital printing machine is also known as omnipotent flatbed printer or flatbed printer, broken through digital printing technology bottleneck, realized that the most genuine one plays the seal, need not the plate-making, full-color image is once accomplished, be the upgrading product of traditional printing machine, at present, digital printing machine in the market carries out the rolling to printing paper at the during operation coiling mechanism, however, need the staff to cut off printing paper manually when taking off the paper winding roller, staff's the operation degree of difficulty has been increased, and with manual cutting surface not parallel and level, influence the pleasing to the eye degree of printing paper, digital printing machine's work efficiency has been reduced simultaneously. And CN211418960U discloses a digital printing machine coiling mechanism, which comprises a frame, winding mechanism and disconnected paper mechanism, the right-hand member of frame is equipped with the winding mechanism who rotates the connection, winding mechanism includes the wind-up roll, guide roll and tensioning roller, the both ends of wind-up roll are rotated with the frame and are connected, the left side of wind-up roll is equipped with guide roll and tensioning roller, the tensioning roller is located between wind-up roll and the guide roll, the both ends of tensioning roller are equipped with the support of rotating the connection, support and the perpendicular fixed connection of frame, the left side of guide roll is equipped with disconnected paper mechanism, disconnected paper mechanism includes the guide bar, threaded rod and slider, guide bar and threaded rod transversely arrange the top of guide roll in, the surface of threaded rod is equipped with the slider of rotating the connection, the top and the guide bar sliding connection of slider. It is through using servo motor drive blade to follow the guide bar motion, conveniently cuts off the printing paper fast, guarantees the notched roughness of paper, improves the aesthetic property of paper cutting, reduces staff's the operation degree of difficulty. However, since the paper is gradually cut by using the servo motor to drive the blade to move along the guide bar, there is still a possibility that uneven paper cuts may be caused due to the difference in the traction force of the paper section during the cutting process.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a winding device of a digital printing machine, which has a simple structure, can quickly cut printing paper and ensure the flatness of paper cuts.

The technical problem to be solved by the utility model is realized by the following technical scheme:

the utility model provides a digital printing machine coiling mechanism, includes wind-up roll and guide roll, still includes air cylinder, last top cylinder, holding down plate and bottom plate down, air cylinder and last top cylinder be fixed in between wind-up roll and the guide roll from top to bottom respectively, just air cylinder and last top cylinder down relative, holding down plate fixed connection in the piston rod of holding down the air cylinder below, bottom plate fixed connection in the piston rod of last top cylinder top, the bottom of holding down plate in the middle of be provided with the cutter, the top of bottom plate in the middle of be provided with the sword groove, the bottom both sides of holding down plate be provided with elasticity hold-down mechanism respectively.

Preferably, the elastic pressing mechanism comprises a spring and a fixing plate, the upper end of the spring is fixedly connected to the bottom of the lower pressing plate, the lower end of the spring is fixedly connected to the upper portion of the fixing plate, and the bottom of the fixing plate is lower than the cutting edge of the cutter.

Has the advantages that: after the structure is adopted, when the printing paper needs to be cut off, the upper jacking cylinder and the lower pressing cylinder are started, the upper jacking cylinder pushes the bottom plate to the position attached to the printing paper, the lower pressing cylinder drives the lower pressing plate to gradually move downwards, the fixing plate gradually presses and fixes the printing paper on two sides of the cutter under the action of the spring, and the cutter cuts the printing paper at one time, so that the function of quickly cutting off the printing paper is realized, the printing paper is synchronously cut at one time, and the flatness of the paper cut is ensured.
