Description

Safe and efficient gilding press

Technical Field

The invention relates to the field of printing equipment, in particular to a safe and efficient stamping machine.

Background

The gold stamping process is a special printing process without ink, wherein gold stamping refers to a process of hot stamping an electrochemical aluminum foil on the surface of a printing stock at a certain temperature and pressure, and a gold stamping machine is equipment for finishing the gold stamping process; gilding press generally has a mount pad of placing the work piece of waiting to gilt, and current mount pad is a ordinary board generally, sets up the recess on the board, when using, places the work piece on the recess, gilt end decline carries out gilt operation to the work piece, but does not set up relevant elasticity canceling release mechanical system in such mount pad, and at gilt end downstream to the in-process of work piece gilt, gilt end can use very big power to strike the work piece of waiting to gilt, so, just probably damage gilt end or work piece.

In order to solve the problems, patent document with application number of CN201620777538.8 discloses a high-efficiency stamping machine capable of protecting a workpiece from being damaged, which comprises a stamping device, wherein an installation seat is arranged right below the stamping device; the mounting seat comprises a mounting seat body, a concave cavity is formed in the mounting seat body, a substrate is arranged on the concave cavity, and an elastic reset mechanism is arranged between the substrate and the bottom of the concave cavity; the substrate is provided with a dividing strip, a first area for placing a workpiece is arranged on the substrate on one side of the dividing strip, and a second area for placing the workpiece is arranged on the substrate on the other side of the dividing strip; the gold stamping device is provided with gold stamping ends for simultaneously carrying out gold stamping operation on two workpieces on the substrate; when the automatic stamping device is used, a workpiece to be stamped is firstly horizontally placed on the substrate of the mounting seat, the stamping device is started, the stamping head of the stamping device stamps the workpiece, and the elastic reset mechanism is arranged below the substrate, so that the impact of the stamping device on the workpiece to be stamped can be buffered, and the workpiece is prevented from being damaged by the stamping device.

The above scheme avoids the damage of the gold stamping device to the workpiece, but has the following problems: the base plate is located gilt device under, and gilt device is continuous up-and-down motion carries out gilt to the work piece, but the work piece is through the manual work with its place on the base plate, when manual operation, gilt device just probably can push down people's hand, causes the safety problem.

Disclosure of Invention

The invention aims to provide a safe and efficient gilding press which is safe to operate and has higher gilding speed.

The safe and efficient gilding press in this scheme, including frame and gilding mechanism, gilding mechanism's lower extreme is provided with gilding end, gilding end's below is provided with the mount pad, be provided with the recess on the mount pad, be connected with first depression bar on the gilding mechanism, articulated on the first depression bar have the pawl, the junction of first depression bar and pawl is provided with the torsional spring, the mount pad includes the disc, the disc rotates to be connected in the frame, the circumference of disc is provided with the teeth of a cogwheel, rotate in the frame and be connected with the ratchet, ratchet and pawl meshing, the ratchet is coaxial to be connected with first bevel gear, first bevel gear meshing has the second bevel gear, second bevel gear is connected with the pivot, be connected with the gear in the pivot, gear and the teeth of a cogwheel meshing on the disc, rotate the cover in the pivot and be equipped with the lantern ring, be connected with the connecting rod on the lantern ring, rotate on connecting rod and frame fixed connection disc and be connected with a plurality of carousel, the recess sets up on the carousel, the both sides of recess all are provided with the logical groove that runs through the carousel, all slide in the logical groove is provided with the slider, opposite one side of slider is the wedge, the upper end of slider is provided with the dog, the lower extreme of slider is connected with the diaphragm.

The technical principle of the scheme is as follows: the frame is used for supporting all mechanisms, the gold stamping mechanism is used as a main body of the gold stamping machine, a gold stamping end at the lower end of the gold stamping mechanism is used for stamping a workpiece, the mounting seat is used for placing the workpiece and is matched with the gold stamping mechanism for stamping the workpiece, the first lower pressing rod is used for driving the pawl to move downwards, the disc is used for supporting and placing the workpiece, when the gold stamping machine is used for stamping the workpiece, the workpiece is placed in the groove on the disc, the gold stamping mechanism moves downwards to drive the first lower pressing rod and the gold stamping end to move downwards, the pawl is driven to move downwards, because the pawl is meshed with the ratchet wheel, the ratchet wheel is not rotated when the pawl moves downwards, an operator can place another workpiece in the groove on the other side of the disc in the descending process of the gold stamping mechanism, when the gold stamping end descends, the operator pushes the slider to move upwards, the gold stamping end is inserted into the slider, if the gold stamping end is misaligned with the gold stamping end, the slider is driven by the slider in the descending process, and after the end is stressed by the slider, the end, the slider is arranged on the turntable, and the turntable is connected with the disc in a rotating way, and the turntable is driven by the slider until the end is aligned with the workpiece. When the gilding mechanism finishes gilding the work piece, gilding mechanism upward movement again, when gilding mechanism upward movement, drive down the depression bar and also upward movement, and then drive pawl also upward movement, pawl upward movement just drives the ratchet rotation, the ratchet rotation drives the coaxial first bevel gear rotation that links to each other, the rotation of first bevel gear drives the rotation of gear through the pivot again, the pivot is when rotating, because there is the support of connecting rod and lantern ring, the pivot rotates steadily, the gear rotation just drives the disc rotation, and then will gilt the work piece that finishes, and place another work piece on the disc and rotate the below of gilt end again, after gilt end below has been rotated to the work piece that finishes, the operator can take out the work piece, and place a work piece newly, because in the in-process of taking down the work piece and placing new work piece, not directly operate under gilt end, when the gilt end descends, can not harm operator's hand, use safelyr.

Compared with the prior art, the beneficial effect of this scheme: 1. according to the scheme, the operation is not performed under the gold stamping end when the work piece which is already gold stamped is taken out and the new work piece is placed, so that the gold stamping end cannot hurt the hands of an operator during the operation, and the operation is safer during the whole gold stamping operation; 2. the gilding press of this scheme is at the taking out of work piece and place the in-process, does not operate in gilding press below, and is safer, so, can increase gilding press mechanism's the speed of pushing down for this gilding press's gilding press efficiency is higher.
