CN2933573Y - Thickness increased blade of paper cutting machine - Google Patents

Abstract

The incrassated blade is used for paper shredder. The blade and knifepoint of the shredder cutter are firstly double decked and then shaped as one layer to become a blade with double thickness. 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 blade that shredder thickens

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 blade that shredder that phenomenon produces thickens 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 the thinner thickness of blade 1011,1012 and blade 1013, easily generation can't shredded paper and cause the phenomenon of paperboard in the shredded paper process; Moreover packing ring 102 mostly is plastic cement material, and 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 blade that a kind of novel shredder thickens finally, can forgo and commonly use the product shortcoming, to promote effect.

Summary of the invention

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

Technical solutions of the utility model: the blade that a kind of shredder thickens, 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:

Two cutting knifes and point of a knife are two-sided long-pending individual layer blade, and it comprises the recessed lamellar body that is converted into monolithic and is cast into bilayer thickness; The centre bore peritreme limit of a wherein blade of cutting knife is protruding with the bulge loop that a circle can supply paper guiding sheet to be nested with.

The utility model beneficial effect: by said structure, the blade that the utility model shredder thickens is the blade and the point of a knife of bilayer thickness, and is more powerful when the cutting paper, and is difficult for paperboard; Moreover, 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 Figure 3, two blades 111,112 stretch out earlier becomes two-sided long-pending blade, and recessed then folding (doubling) becomes monolithic and is cast into the lamellar body of bilayer thickness; 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 ', 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.

Claims (1)

1. blade that shredder thickens, 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:

Two cutting knifes and point of a knife are two-sided long-pending individual layer blade, and it comprises the recessed lamellar body that is converted into monolithic and is cast into bilayer thickness; The centre bore peritreme limit of a wherein blade of cutting knife is protruding with the bulge loop that a circle can supply paper guiding sheet to be nested with.
