Description

Offset hot stamping unit

technical field

The utility model relates to an offset printing hot stamping unit matched with an offset printing machine.

Background technique

At present, offset printing machines can only complete offset printing. If some offset printed paper needs to be hot stamped, it needs to be completed by an independent hot stamping unit, which is very inconvenient, low production efficiency, and high production cost, which is not conducive to market competition.

Contents of the invention

In view of the deficiencies in the prior art, the purpose of this utility model is to provide an offset printing and hot stamping unit that can be used on offset printing machines, which can realize simultaneous offset printing and bronzing, improve production efficiency, and has a simple structure and good bronzing quality.

The utility model is accomplished by taking the following technical solutions:

The offset printing and hot stamping unit includes a frame, which is characterized in that: the upper part of the frame is equipped with unwinding and rewinding shafts on the left and right, the reeling shaft is connected to the first motor, and the lower part of the frame is equipped with upper and lower rollers, and the upper and lower rollers are close to each other during work Pressing, the upper roller is a heating roller, the upper roller can be adjusted, the lower roller is connected with the second motor drive, and the right deviation guide roller, the first traction guide roller group, The right floating guide roller group and the second traction guide roller group are successively provided with the third traction guide roller group, the left floating guide roller group, the fourth traction guide roller group and the left deviation correction guide roller from the upper and lower rollers to the unwinding shaft.

The offset printing hot stamping unit of the above technical solution is matched with the offset printing machine and has a simple structure. Its working principle is: when working, the bronzing tape roll material is placed on the unwinding reel, and the bronzing tape passes through the deflection correction of the left deflection correction guide roller, and the fourth traction guide roller group The traction of the left floating guide roller group, the traction of the third traction guide roller group, the middle of the upper and lower rollers, the traction of the second traction guide roller group, the adjustment of the right floating guide roller group, the traction of the first traction guide roller group 1. The deviation of the right guide roller is rectified and wound up on the winding shaft. When the bronzing belt passes through the middle of the upper and lower rollers, it is pressed between the upper and lower rollers and heated by the upper roller, so the gold powder on the bronzing belt is hot-blasted. When working, it also passes through the post-press or pre-press paper between the upper and lower rollers to complete the real-time synchronous action process of offset printing and hot stamping, which improves production efficiency and has good stamping quality.

As a preference, both ends of the shaft of the upper roller are rotatably supported by eccentric bushings, the eccentric bushings are rotated in the bushing installation holes of the frame wallboard, and the rotation of the eccentric bushings is driven by the first cylinder. The above-mentioned design can realize the convenient adjustment operation of the upper roller.

Preferably, the upper roller is heated by circulating oil. Make the heating temperature uniform and improve the bronzing quality.

As preferably, the first traction guide roller group includes A roller and B roller that are pressed close to each other during work, A roller is fixedly set and connected to the first motor transmission, and B roller is movable and set to be pushed by the second cylinder; the second pull The guide roller set includes the C roller and the D roller that are pressed against each other during work. The fixed setting of the C roller is connected to the third motor drive, and the movable setting of the D roller is driven by the third cylinder; Compressed E roller and F roller, the fixed setting of E roller is connected with the third motor transmission, and the movable setting of F roller is driven by the fourth cylinder; the fourth traction guide roller group includes G roller and H roller that are close to each other and pressed tightly during work , the fixed setting of the G roller is connected with the transmission of the fourth motor, and the movable setting of the H roller is driven by the fifth cylinder.
