Description

Counterweight assembly of printing roller

Technical Field

The invention belongs to the technical field of machinery, and relates to a counterweight assembly of a printing roller.

Background

The printing roll is an important accessory of offset printing machines. In order to ensure the printing quality, the printing roller usually has a certain weight.

However, in order to ensure sufficient weight of the conventional printing roll, the thickness of the cylindrical printing roll is generally set to be relatively large. Although the printing stability is solved, the material consumption is large, and the manufacturing cost of the printing roller is increased.

Disclosure of Invention

The invention aims to solve the problems in the prior art and provide a counterweight assembly of a printing roller, which can improve the stability of the printing roller and has a compact structure.

The purpose of the invention can be realized by the following technical scheme:

the utility model provides a counter weight component of printing roller, printing roller is including being cylindric barrel, its characterized in that, and this subassembly includes that the barrel inboard is the concave spread groove of annular, still includes two and is curved counter weight strips: the strip body I and the strip body II are hinged to each other, the inner end of the strip body I is hinged to the inner end of the strip body II, the outer sides of the strip body I and the strip body II are embedded in the connecting groove, and a clamping structure capable of clamping the connecting groove and the strip body I is arranged between the connecting groove and the strip body I.

This counter weight component creatively inlays strip body one and strip body two in spread groove department, with the stable location of strip body on the body under the effect of joint structure. Because the first strip body is connected with the second strip body, the first strip body and the second strip body are stably connected to the body.

Because the first strip body and the second strip body are made of materials with higher density, for example: and (4) casting iron. Therefore, the printing roller can have enough weight under the action of the first strip body and the second strip body, so that the printing roller can perform normal and stable printing operation.

In the counter weight component of foretell printing roller, the joint structure include the recessed locating hole of a strip body lateral part, spring and ball have in the locating hole, above-mentioned ball stretches out the locating hole under the spring action of spring part down, and the ball has the trend of leaning on at the spread groove lateral wall department.

Under the action of the elastic force of the spring, the ball can stably abut against the shell.

In the above-described weight assembly of the printing roller, the connecting groove has a recessed positioning notch at a side wall thereof.

In the above-described weight assembly of the printing roller, the positioning recess is matched with the side of the ball.

The strip body can be more stably positioned on the body through the positioning notch.

In the above-described weight assembly of the printing roller, the bottom of the connecting groove has a flexible contact pad.

The strip-body can be prevented from rigidly contacting the body by the flexible contact pad.

In the counterweight assembly of the printing roller, the contact pad comprises a first long plate body, a second long plate body and a third long plate body, the first long plate body abuts against the bottom of the connecting groove, the third long plate body abuts against the first strip body, and the second long plate body is tightly pressed between the first long plate body and the third long plate body.

In the counterweight assembly of the printing roller, the first plate body and the third plate body are both made of rubber materials, and the second plate body is made of wood materials.

The first plate body and the third plate body enable the contact pad to have enough flexibility, and the second plate body can properly improve the strength of the contact pad.

The weight assembly of the printing roller further comprises a flexible cushion block, and the cushion block is tightly pressed between the outer end of the strip body and the outer end of the strip body.

Because the cushion block is pressed tightly between the outer ends of the first strip body and the second strip body, the first strip body and the second strip body can be stably embedded in the connecting groove.

In the above-mentioned counter weight assembly of printing roller, the cushion includes the body and keeps off along, and above-mentioned body is isosceles trapezoid, and above-mentioned fender along protrusion in the small-size top both sides of body, and the both sides waist limit department that leans on respectively at above-mentioned strip body outer end and strip body outer end supports and leans on in the strip body inboard, and the opposite side that keeps off along leans on in the strip body inboard.

The two sides of the body can be stably contacted by the outer end of the first strip body and the outer end of the second strip body, and the whole cushion block can be stably positioned between the first strip body and the second strip body under the action of the blocking edge.

In the counterweight assembly of the printing roller, the body and the blocking edge are of an integrated structure and are made of rubber materials.

Compared with the prior art, the counterweight assembly of the printing roller has the advantages that the strip body I and the strip body II have enough weight, so that the strip body I and the strip body II which are connected inside the printing roller can enable the whole printing roller to have enough weight, the consumption of materials of a printing cylinder can be properly reduced, the cost of the printing roller is effectively reduced, and the stability is higher.

Meanwhile, the first strip body and the second strip body are both positioned in the barrel body, and do not occupy extra space, so that the structure is compact, and the high-efficiency barrel is high in practical value.
