Description

Automatic cutting device of high efficiency

Technical Field

The utility model relates to an automatic cutting device of high efficiency belongs to gravure printing equipment technical field.

Background

The fixed single-station winding and unwinding gravure printing machine needs to be stopped to operate if a material film needs to be replaced, so that the working efficiency is influenced on the one hand, and on the other hand, the machine needs to be restarted due to tension change caused by stopping, the machine needs to be registered again, the overprinting precision of the material film which is not printed in the printing machine cannot be influenced, so that waste products are caused, and the modern high-speed gravure printing machine mostly adopts a double-station winding and unwinding system to realize automatic and quick material changing. When the double-station winding and unwinding is carried out and the roll is rapidly changed, the original roll film needs to be automatically cut off and then is adhered to a new roll, so that the automatic roll change is realized. The existing automatic cutting device is mostly in a swing arm structure, swing arms on the left side and the right side are controlled to swing through independent cylinders, and the problem of poor rotation synchronism of the swing arms on the two sides exists; when cutting, the material film is unstable in operation, so that the cutting failure rate is high, and a cutting tool apron and a cutting tool can be damaged in serious conditions.

Disclosure of Invention

An object of the utility model is to overcome the aforesaid not enough, provide a swing arm and rotate high efficiency automatic cutting device that the synchronism is good, cutting efficiency is high, the fault rate is low.

The purpose of the utility model is realized like this:

a high-efficiency automatic cutting device comprises left and right side wall plates of an intaglio printing press, main radial arms symmetrically arranged on the two side wall plates in a left-right mode, and a compression roller and a cutting knife arranged on the main radial arms, wherein the right ends of the main radial arms are hinged to side wall plates, the middle parts of the main radial arms are hinged to the side wall plates through radial arm cylinders, and a supporting stop and a guide roller shaft are fixedly arranged between the left main radial arm and the right main radial arms; a guide roller and a cutter rotating arm are arranged on the guide roller shaft in a rolling manner; the upper ends of the cutter swing arms on the left side and the right side are fixedly connected with a cutter frame, the cutter frame is provided with a cutting cutter, and the lower ends of the cutter swing arms are hinged with the main swing arm through a cutter cylinder.

Furthermore, the compression roller is hinged to the main spiral arm through a compression roller spiral arm and a compression roller cylinder.

Furthermore, the compression roller is rotatably arranged on the compression roller spiral arm through an eccentric bearing

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model has the advantages that the supporting gear and the guide roll shaft are fixedly arranged between the main swing arms at the two sides, so that the integral rigidity of the main swing arms at the two sides is enhanced, and the problem of poor rotation synchronism of the swing arms at the two sides is avoided; the guide roller and the compression roller on the main spiral arm are used for controlling the material film to run stably during cutting, the cutting failure rate is low, and the efficiency is high.

Wherein:

the side wall plate comprises a side wall plate 1, a main spiral arm 2, a press roller 3, a cutting knife 4, a spiral arm cylinder 5, a supporting block 6, a guide roller shaft 7, a guide roller 8, a cutting knife spiral arm 9, a cutting knife rest 10, a cutting knife cylinder 11, a press roller spiral arm 12, a press roller cylinder 13 and an eccentric bearing 14.

Detailed Description

Referring to fig. 1 to 3, the utility model relates to a high-efficiency automatic cutting device, which comprises left and right side wall plates 1 of an intaglio printing press, main radial arms 2 arranged on the side wall plates 1 in bilateral symmetry, and a compression roller 3 and a cutting knife 4 arranged on the main radial arms 2, wherein the right ends of the main radial arms 2 are hinged on the side wall plates 1 through bearings and bearing seats, the middle parts of the main radial arms 2 are hinged with the side wall plates 1 through radial arm cylinders 5, and supporting gears 6 and guide roller shafts 7 are fixedly arranged between the left and right main radial arms 2, so that the rigidity stability and consistency of the left and right main radial arms 2 during rotation are ensured; a guide roller 8 and a cutter rotating arm 9 are arranged on the guide roller shaft 7 in a rolling manner through a bearing; a cutting knife rest 10 is fixedly connected between the upper ends of the cutting knife swing arms 9 positioned at the left side and the right side of the guide roller 8, cutting knives 4 are installed on the cutting knife rest 10, and the lower ends of the cutting knife swing arms 9 are hinged with the main swing arm 2 through a cutting knife cylinder 11; the compression roller 3 is rotatably arranged at one end of the compression roller spiral arm 12 through an eccentric bearing 14, the middle of the compression roller spiral arm 12 is rotatably arranged on the main spiral arm 2, and the other end of the compression roller spiral arm 12 is hinged with the main spiral arm 2 through a compression roller cylinder 13.

When the winding and unwinding mechanism changes the roll, the spiral arm cylinder 5 puts down the main spiral arm 2, the guide roller 8 presses the roll material downwards, the compression roller cylinder 13 drives the compression roller 3 to press downwards, so that the material film between the guide roller 8 and the compression roller 3 is stretched tightly and smoothly, the cutter cylinder 11 pushes the cutter spiral arm 9 to rotate to drive the cutting knife 4 to press downwards, the material film is cut off, and then the roll changing operation is completed. Because the supporting bar 6 and the guide roll shaft 7 are fixedly arranged between the left main radial arm 2 and the right main radial arm 2, the integral rigidity of the two main radial arms 2 is improved, and when the radial arm cylinder 5 pushes the main radial arms 2 to rotate, the two main radial arms 2 can be ensured to rotate synchronously; the press roller 3 provided with the eccentric bearing 14 can finely adjust the tension on the left side and the right side of the material film to enable the material film to be smoother and improve the cutting power.

In addition: it should be noted that the above-mentioned embodiment is only an optimized solution for this patent, and any modification or improvement made by those skilled in the art based on the above-mentioned conception is within the protection scope of this patent.
