Abstract
The utility model relates to the technical field of paper shredders, in particular to a knife rod component of a paper shredder, which includes a knife rod and a knife blade, a sleeve hole is formed on the knife blade, at least one V-shaped groove is formed on the outer surface of the knife rod, the sleeve hole of the knife blade is sleeved on the knife rod, a V-shaped outward projecting sharp part matched with the V-shaped groove is formed on the inner side of the sleeve hole of the knife blade, the V-shaped outward projecting sharp part is clamped in the V-shaped groove, the V-shaped groove on the knife rod can position the knife blade and prevent the knife blade from rotating freely relative to the knife rod, a sleeve ring part is eliminated, the machining process is simplified, the production efficiency is higher, and the structure can eliminate the sleeve ring on the knife rod of a machine core on the basis of no influence on the paper shredding function, therefore, the paper shredders with the same specifications can have proper reductions in knife rod diameter and knife blade external diameter, and the cost is reduced.
Description
Technical field:
The utility model relates to the shredder technical field, particularly a kind of kneader knife rod assembly.
Background technology:
Shredder is made up of shell, movement, circuit board and motor, and paper is sent in the middle of the blade of the mutual interlock of movement, is divided into a lot of tiny scraps of paper, to reach secret purpose.The shredded paper mode is meant after paper is handled through shredder by the shape after the paper shredding blade chopping.According to the composition mode of paper shredding blade, existing shredded paper mode has: broken shape, granular, section shape, foam shape, strip, thread etc.The shredder movement generally includes the cylindrical shape hobboing cutter wheel that a pair of rightabout rotates, cylindrical shape hobboing cutter wheel is then assembled by cutter rod and a plurality of blade that is separated with spacer ring between being placed on the cutter rod, two cylindrical shape hobboing cutter wheels are installed in parallel on the knife rest side by side, each blade of arranging on the two cylindrical shape hobboing cutters is corresponding one by one tangent, forms a plurality of paper shredding blade clips.
Because the moment of torsion that the cutter rod is subjected to is bigger, in order to prevent to relatively rotate between blade and the cutter rod, the cutter rod assembly that shredder is arranged now all is to increase the collar between blade and cutter rod, the cutter rod is made polygon structure, the polygon with the corresponding coupling of cutter rod is also made in the inboard of the collar, the collar is set on the cutter rod, can prevent to relatively rotate between the collar and the cutter rod, blade then tightly is socketed in the outside of the collar, and the part of this cutter rod assembly is more, the processing more complicated, lose time, production cost is higher, and assembling the time need wear the collar earlier and wear paper guiding sheet and blade again, and mounting or dismounting are inconvenient.
The utility model content:
The purpose of this utility model is to provide at the deficiencies in the prior art a kind of kneader knife rod assembly that the V-type groove replaces the collar, enhances productivity, reduces production costs of offering on the cutter rod.
For achieving the above object, the utility model adopts following technical scheme:
A kind of kneader knife rod assembly, it includes cutter rod and blade, offer trepanning on the blade, offer at least one V-type groove on the outer surface of cutter rod, the trepanning of blade is set on the cutter rod, the trepanning inboard of blade forms the V-type convex tip with the corresponding coupling of V-type groove, and the V-type convex tip is fastened in the V-type groove.
Described cutter rod is circular mandrel rod.
Described V-type groove is many, and many V-type grooves evenly distribute along the circumferencial direction of cutter rod.
Described V-type groove is along the axial directional distribution of cutter rod.
Described V-type groove also can be the axial direction spiral distribution along the cutter rod.
The utility model beneficial effect is: the utility model includes cutter rod and blade, offer trepanning on the blade, offer at least one V-type groove on the outer surface of cutter rod, the trepanning of blade is set on the cutter rod, the trepanning inboard of blade forms the V-type convex tip with the corresponding coupling of V-type groove, the V-type convex tip is fastened in the V-type groove, V-type groove on the cutter rod can not rotate freely by phase tool setting rod blade by positioning blade, saved collar part, simplified process, production efficiency is higher, can be on the basis that does not influence the shredded paper function, can save the collar on the movement cutter rod by this structure, therefore, on the same specification shredder, can reduce the diameter and the blade external diameter of cutter rod again in right amount, thereby reduce cost.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a generalized section of the present utility model;
Fig. 3 is the structural representation of the utility model cutter rod;
Fig. 4 is the structural representation of the utility model blade.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described, see Fig. 1～4, a kind of kneader knife rod assembly, it includes cutter rod 1 and blade 2, offer trepanning 22 on the blade 2, offer at least one V-type groove 11 on the outer surface of cutter rod 1, the trepanning 22 of blade 2 is set on the cutter rod 1, trepanning 22 inboards of blade 2 form the V-type convex tip 21 with V-type groove 11 corresponding couplings, and V-type convex tip 21 is fastened in the V-type groove 11.
Wherein, cutter rod 1 is processed into circular mandrel rod, and is easy to process, saves cost, and paper guiding sheet 3 can directly be located on the circular knife rod 1.V-type groove 11 and V-type convex tip 21 all are two, and two V-type grooves 11 evenly distribute along the circumferencial direction of cutter rod 1, and certainly, V-type groove 11 and V-type convex tip 21 also can be 3,4 or more.V-type groove 11 also can be the axial direction spiral distribution along cutter rod 1 along the axial directional distribution of cutter rod 1.
V-type groove 11 on the utility model cutter rod 1 can not rotate freely by phase tool setting rod 1 blade 2 by positioning blade 2, saved collar part, simplified process, production efficiency is higher, can be on the basis that does not influence the shredded paper function, can save the collar on the movement cutter rod 1 by this structure, therefore, on the same specification shredder, can reduce the diameter of cutter rod 1 and the external diameter of blade 2 again in right amount, thereby reduce cost.
Certainly, the above only is preferred embodiment of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
