Abstract

The integrated blade device is used for paper shredder. At least one convex ring integrated with the blade is fixed in each cutter group of the secondary hob, when connecting with the convex ring or blade of another blade, the convex can not only guide paper slip device but also keep the shape when heated or cooling, no space is produced between the two blades, thereby the device can avoid the problems of paper block or blades block.

Description

The integrated blade structure of shredder

Technical field

The utility model refers to especially that relevant for a kind of kneader knife chip architecture a kind of two blades that prevent produce the gap because of rising-heat contracting-cold, forms paperboard or the upper and lower blade integrated blade structure of shredder that phenomenon produces that is stuck.

Background technology

The cutter for paper grinder of traditional type as shown in Figure 1, form by two groups of cylindrical shape hobboing cutters 100,100 ', each group hobboing cutter 100,100 ' is made up of several cutting knifes 101, several packing rings 102 and an axostylus axostyle 103, socket one packing ring 102 between the wherein adjacent cutting knife 101, axostylus axostyle 103 run through cutting knife 101 and are assembled into hobboing cutter 100,100 ' with packing ring 102; And each cutting knife 101 is abutted against by two

blades

1011,1012 and forms, and is respectively equipped with at least one point of a knife 1013 on two blades, 1011,1012 peripheries, and the paper guiding sheet that packing ring 102 peripheries are nested with a C shape; Because packing ring 102 mostly is a plastic cement material, shredder can produce heat in the shredded paper process, and packing ring 102 easily produces tired, rising-heat contracting-cold packing ring 102 as a result can dwindle, the space that adjacent two cutting knifes are 101 then can be strengthened, and except easy paperboard, upper and lower blade also easily is stuck.

In view of this utility model people accumulates and is engaged in the industry experience for many years, is study intensively and test improvement repeatedly, nowadays creates the integrated blade structure of a kind of novel shredder finally, can forgo and commonly use the product shortcoming, to promote effect.

Summary of the invention

The utility model, purpose is to provide a kind of shredder integrated blade structure, the plastic washers that replaces the traditional type cutter by bulge loop, to reduce material, to reduce cost, and the packing ring of metal can not dwindle because of the heat that shredded paper produced, and prevents that the phenomenon that paperboard or upper and lower blade are stuck from taking place.

Technical solutions of the utility model: the integrated blade structure of a kind of shredder, described cutter for paper grinder is made up of two groups of cylindrical shape hobboing cutters, each group hobboing cutter is made up of several cutting knifes and an axostylus axostyle, each cutting knife is abutted against by two blades and constitutes, have one or more point of a knife respectively on the two blade peripheries, it is characterized in that:

The centre bore peritreme limit of the blade among the cutting knife is protruding with a circle bulge loop that can supply paper guiding sheet to be nested with.

The utility model beneficial effect: the integrated blade structure of the utility model shredder, on at least one blade of cutting knife, be convexly equipped with a circle bulge loop, the packing ring that replaces traditional type plastic cement system, with the integrated metal system bulge loop of blade except providing paper guiding sheet is nested with, rising-heat contracting-cold can not be out of shape yet in the shredded paper process, become big with the gap of avoiding two blades, so can prevent the phenomenon generation that is stuck of paper jam phenomenon and upper and lower blade.

Understand in order to allow the auditor that the utility model is had further, Zi Zuo is as follows with graphic detailed description the utility model.

The specific embodiment

See also shown in Figure 2, cutter for paper grinder of the present utility model is made up of two groups of cylindrical shape hobboing cutters 10,10 ', each group hobboing cutter 10,10 ' is made up of several cutting knifes 11 and an axostylus axostyle 12, each cutting knife 11 is abutted against by two blades 111,112 and forms, be respectively equipped with at least one point of a knife 113 on two blades, 111,112 peripheries, be primarily characterized in that:

As shown in Figures 3 and 4, the polygon centre bore 110 peritreme limits of a wherein blade 111 of cutting knife 11 are convexly equipped with a circle bulge loop 114, this bulge loop 114 is one-body molded with blade 111, the mode moulding of available machines used punching press on making, the polygon centre bore 110 peritreme limits of cutting knife 11 another sheet blades 112 also are convexly equipped with a circle and blade 112 integrated bulge loops 114 ', cooperate shown in Figure 4, by the mode of putting and connect and form, wherein the big bulge loop 114 of a blade 111 abuts against little bulge loop 114 ' another lateral margin of another blade 112 to each cutting knife 11 with two blades 111,112; Because the bulge loop 114 that a cutting knife 111 is convexly equipped with can be nested with for paper guiding sheet, this bulge loop 114 has replaced the plastic washers of traditional type, metal bulge loop 114 rising-heat contracting-cold in the shredded paper process can not be out of shape yet, so can avoid two blades 111,112 between the space become big, be stuck with the blade 111,112 that prevents paper jam phenomenon or upper and lower cutting knife.

Consult shown in Figure 5, of the present utility model another implemented illustration, wherein a blade 111 centre bore peritreme limits of cutting knife 11 are convexly equipped with a circle bulge loop 114, and the centre bore peritreme limit of another blade 112 is not convexly equipped with bulge loop, and the bulge loop 114 of blade 111 rests on another blade 112 bodies.

Consult shown in Figure 6, another enforcement illustration of the present utility model, wherein two blades, 111, the 112 centre bore peritreme limits of cutting knife 11 bulge loop 114,114 ', two bulge loops 114,114 ' that are convexly equipped with identical size respectively are abutted against moulding mutually, are nested with for paper guiding sheet with common.

Claims

1. integrated blade structure of shredder, described cutter for paper grinder is made up of two groups of cylindrical shape hobboing cutters, and each group hobboing cutter is made up of several cutting knifes and an axostylus axostyle, and each cutting knife is abutted against by two blades and constitutes, have one or more point of a knife respectively on the two blade peripheries, it is characterized in that:

The centre bore peritreme limit of the blade among the cutting knife is protruding with the bulge loop that a circle can supply paper guiding sheet to be nested with.
