Abstract

The utility model relates to a round cutter with four cutting edges, which is composed of a cuter body, a cutter shaft, and a cutter pad. Four cutting edges 2, 3, 4, 5 are arranged on the circumference of the cutter body 1, a screw thread 7 and a keyway 8 is respectively arranged on both ends of the cutter shaft 6, and a step stand 10, 11 are respectively arranged on the two sides of the periphery of the cutter pad 9 to form a double-trimming cut type cutter pad. Compared with the universal round cutter with a single cutting edge used in industries such as the paper industry, the tobacco industry, the match industry, etc., the steel utilization ratio of the utility model is increased by four times. Compared with the round cutter with double cutting edges, the steel utilization ratio of the utility model is increased by two times and the user revenue is improved by more than 50 %.

Description

Cutting tool for cutting cycle with four direction edge

The utility model relates to the cutter of cutting machine; The lower round knife tool that particularly relates to cutting machine.

Cutting machine is must obligato cutting mechanics in the industrial production such as papermaking, tobacco, match.Domestic general cutting machine lower round knife all is the structure of single face sword at present, promptly on the circumference of cutter hub, has only a side to have blade.The lower round knife of this single face sword can only disposablely use, in case the blade blunt, the cutter that will more renew.So from the used steel of cutter, to the processing and manufacturing of cutter, and in use change cutter overfrequency etc., all cause a large amount of wastes of human and material resources and financial resources, particularly frequent replacing cutter, the operating efficiency that directly has influence on cutting machine can not improve effectively.

At above present situation, the applicant discloses a kind of double-sided blade that can secondary uses and has cut lower round knife in ZL922196907 number utility model patent file, to improving steel utilization ratio.Improve work efficiency, save and all obtain technical economic benefit preferably in man-hour etc.But after this, the applicant is by concrete practice, finds that above-mentioned double-sided blade cuts lower round knife at perfect frame further with improve steel utilization ratio, improve work efficiency, save aspect such as man-hour and still have than potentiality greatly and can dig.

The purpose of this utility model is exactly on the basis of ZL922196907 patented technology, the structure of cutter is done further improved, and improves twice thereby make steel utilization ratio cut lower round knife than double-sided blade again, and makes the user be benefited raising more than 50%.

Specific embodiments of the present utility model is as follows: at first, on ZL922196907 patent basis, change the cutter hub of lower round knife into the four sides sword by two-edged knife; Secondly, novel cutter shaft and edge bearing have correspondingly been designed again.Wherein:

1, the two ends of cutter shaft all are designed to be threaded structure with keyway, thereby make cutter shaft both can reverse end for end to use, again can be by fine setting conversion blade;

2, provide one with cutter hub and the supporting two side cut edge bearings of cutter shaft.

The a of Fig. 1 and b are structure of the cutter body schematic diagrames of the present utility model;

Fig. 2 is a cutter shaft structure schematic diagram of the present utility model;

The a of Fig. 3 and b are edge bearing structural representations of the present utility model;

Fig. 4 is a local assembled condition schematic diagram of the present utility model.

Followingly specific embodiments of the present utility model is described in detail with reference to accompanying drawing.

1, as shown in Figure 1, four

blades

2,3,4,5 are arranged on the circumference of cutter hub 1;

2, as shown in Figure 2, at the two ends of cutter shaft 6, a screw thread 7 and keyway 8 are arranged respectively

3, as shown in Figure 3, in the peripheral both sides of edge bearing 9, a stage 10,11 is arranged respectively; Edge bearing both can have been cut the width dimensions of material in order to adjusting, can protect blade injury-free again.

Using method of the present utility model: as shown in Figure 4, cutter hub 1 and edge bearing 9 interval group successively are contained on the cutter shaft 6 (general every cutter shaft can be adorned 32-50 sheet cutter hub) can select according to the width of cutting material as for edge bearing thickness required between two cutter hubs.When cutting operation, will go up earlier on a certain blade that dise knife aligns lower round knife (for example aligning blade 2 earlier), when this blade passivation, the nut 12 on the rotatable cutter shaft makes the blade 4 of lower round knife align with last dise knife by fine setting, can continue to cut operation.When the blade of same side all during passivation, cutter shaft is turned 180 °, can use each blade of another side by above-mentioned method successively instead.

The utility model is compared with the two-face blade cutting knife tool, and structure is more novel, use is more nimble, effect is more superior; Particularly as three parts of solid tool, i.e. the structure that complements each other that consists of of cutter hub, cutter shaft and two side cut edge bearing, the Technological Economy that has more wide popularization and application is worth.

Claims

1, a kind of four sides sword is cut the lower round knife tool, and it is that one group of cutter hub and edge bearing interval group are contained on the cutter shaft, and it is characterized in that has four blades (2), (3), (4), (5) on the circumference of cutter hub (1);

2, cut the lower round knife tool according to the described four sides of claim 1 sword, it is characterized in that, a screw thread (7) and keyway (8) are respectively arranged at the two ends of cutter shaft (6);

3, cut the lower round knife tool according to the described four sides of claim 1 sword, it is characterized in that a stage (10), (11) respectively being arranged, constitute the edge bearing of a kind of pair of side cut shape in the peripheral both sides of edge bearing (9).
