Abstract

The utility model provides a material-receiving cutter device for unit-type gravure printing machine and compound machine, comprising a cutter arm, a cutter cylinder and a cutter; a swing arm and an accelerating device are fixed on the cutter arm; the cutter and a brush are fixed on the swing arm; the accelerating device comprises a fan gear and a cylinder gear; the shaft which is connected with the swing arm and the cylinder gear of the accelerating member is arranged on the cutter arm; the fan gear and the cutter cylinder are hinged by a hinge. A cutter terminal buffer device is arranged on the cutter arm to decrease the impact after material receiving is accelerated. The material-receiving cutter device eliminates and solves the problem of waste products caused by that a part of material film always exist at the innermost layer of the material roll or wrinkle occurs upon compound film effectively, decreases waste products to the maximum degree and improves the ratio of finished products.

Description

A kind of set type intaglio press and compounding machine rewinding cut-off knife device

Technical field

The utility model relates to the material collecting device of set type intaglio press, or rather, relates to a kind of set type intaglio press and compounding machine rewinding cut-off knife device.

Background technology

Existing high-grade set type intaglio press and high-grade compounding machine are in the double automatic material connection process of rewinding; when the old material diameter that furls when reaching requirement; can under non-stop-machine state, finish old coiled strip is cut off, stub bar is wound into the automatic material connection process on the rewinding tube core of new axle.But exist problem be: when pressure roller will expect mould at new rewinding tube core in a flash, cut-off knife cuts off the material film between new axle rewinding tube core and the old volume, this moment is because stub bar loses tension force, on the rewinding tube core of the new axle of twisting in of irregular, because the effect of the stub bar of these irregulars, thereby cause expecting that total some material film in the innermost layer of rolling up or complex film wrinkle occurs and cause waste product.

Summary of the invention

At the existing defective of rewinding cut-off knife device in the prior art, in order to reduce waste product, improve yield rate, the utility model provides a kind of set type intaglio press and compounding machine rewinding cut-off knife device.

The purpose of this utility model is achieved through the following technical solutions: a kind of set type intaglio press and compounding machine rewinding cut-off knife device, comprise the big arm of cut-off knife, cut-off knife cylinder and cut-off knife, on the big arm of cut-off knife, fix a swing arm and acceleration mechanism, be fixed with cut-off knife and hairbrush in the described swing arm; Described acceleration mechanism comprises elevating arc and cylindrical wheel, and the axle mounting that connects swing arm and acceleration mechanism cylindrical wheel is on the big arm of cut-off knife; Described elevating arc is that hinge is connected with the cut-off knife cylinder.

In order to reduce the impact that connects material after quickening, a cut-off knife terminal suspending mechanism is set on the big arm of cut-off knife.

Compared with prior art, the utlity model has following beneficial effect:

1,, can actv. eliminates and solves that wrinkle appears in total some the material film in innermost layer of material volume or complex film and the problem that causes waste product owing to adopt the cut-off knife device of this structure;

2, reduce waste product to a great extent, improved yield rate;

3, simple in structure, dependable performance, practicality.

Description of drawings

Accompanying drawing is the structural representation of the utility model rewinding cut-off knife device.

Among the figure: 1. the big arm of cut-off knife, 2. cut-off knife cylinder, 3. cut-off knife, 4. pressure roller, the 5. new reel core of receiving, 6. hairbrush, 7. buffer gear, 8. swing arm, 9. elevating arc, 10. spool, 11. cylindrical wheels, 12. old volumes.

The specific embodiment

Below in conjunction with drawings and the specific embodiments the utility model is done detailed explanation.

In figure, be fixed with swing arm 8, elevating arc 9, axle 10 and cylindrical wheel 11 on the big arm 1 of cut-off knife.When old volume 12 rewinding diameters reach requirement and need change of lap, cut pressure roller 4 will expect mould new when receiving reel core 5 in a flash, cut-off knife cylinder 2 stretches out, and drives elevating arc 9 swings, thereby cylindrical wheel 11 is rotated.Therefore, the material film that causes the cut-off knife 3 in the swing arm 8 will newly receive between reel core 5 and the old volume 12 cuts off, and at the severing stub bar in a flash, receives on the reel core 5 new with the brush that the hairbrush 6 in the swing arm 8 is smooth with stub bar.So just avoided stub bar by on the rewinding tube core of the new axle of twisting in of irregular.Actv. eliminates and solves that wrinkle appears in total some material film in innermost layer of material volume or complex film and the problem that causes waste product.In order to ensure the effect that connects material, we have increased the cutting knife acceleration mechanism of elevating arc 9, axle 10, cylindrical wheel 11, and the severing of cutting knife speeded up.

In order to reduce the impact of elevating arc 9, increased cutting knife terminal suspending mechanism 7.

Claims

1. set type intaglio press and compounding machine rewinding cut-off knife device comprise the big arm of cut-off knife, cut-off knife cylinder and cut-off knife, fix a swing arm and acceleration mechanism on the big arm of cut-off knife, are fixed with cut-off knife and hairbrush in the described swing arm; Described acceleration mechanism comprises elevating arc and cylindrical wheel, and the axle mounting that connects swing arm and acceleration mechanism cylindrical wheel is on the big arm of cut-off knife; Described elevating arc is that hinge is connected with the cut-off knife cylinder.

2. set type intaglio press according to claim 1 and compounding machine rewinding cut-off knife device is characterized in that: a cut-off knife terminal suspending mechanism is set on the big arm of cut-off knife.
