Abstract
The utility model belongs to shredder technical field, specifically involve in and relate to a kind of paper shredder core with cutter shaft reinforcement structure, include two cutter shafts and several set of blades be arranged on cutter shaft, described cutter shaft two ends are arranged on little side plate and large side plate respectively, be provided with fixed head and be connected between little side plate with large side plate; The sidepiece of cutter shaft is respectively equipped with at least one back-up block, and described back-up block withstands on the spacer between the cutter ring cylindrical of cutter shaft or set of blades, and back-up block is supported by fixed head.Adopt the back-up block of low cost to carry out the support of knife pivot of paper crusher, reduce costs and increase the intensity of cutter shaft, and cutter shaft and blade can be reduced thus, reaching the effect that existing shredder is same.
Description
Technical field
The utility model belongs to shredder technical field, specifically involves in and relates to a kind of paper shredder core with cutter shaft reinforcement structure.
Background technology
Shredder is a kind of instrument that office is commonly used, can will be loaded with shredding without file of important information, prevent information material from leaking, existing shredder is when shredded paper, because cutter shaft rigid is limited, one time paper is more or thicker, will make the middle part of cutter shaft outwards produce certain curved by, easily cause shredder shredded paper not open, broken constantly and tatter amount reduce.And the rigidity strengthening cutter shaft comparatively difficulty and limited, and change high-quality steel cost more can be made significantly to improve.
Summary of the invention
For problems of the prior art, the utility model provides a kind of to be had cutter shaft and strengthens the paper shredder core of structure, strengthens cutter shaft, prevents bending and affects the effect of shredded paper.
The utility model realizes by the following technical solutions:
There is provided a kind of and have the paper shredder core that structure strengthened by cutter shaft, include two cutter shafts and several set of blades be arranged on cutter shaft, described cutter shaft two ends are arranged on little side plate and large side plate respectively, be provided with fixed head and be connected between little side plate with large side plate; The sidepiece of cutter shaft is respectively equipped with at least one back-up block, and described back-up block withstands on the spacer between the cutter ring cylindrical of cutter shaft or set of blades, and back-up block is supported by fixed head.
Further, described back-up block is provided with multiple support chip, and support chip is provided with the recess matched with cutter ring cylindrical or spacer.
Further, movement also include lead paper bag and under lead paper bag, lead on described paper bag and under lead paper bag and be all arranged on respectively between two fixed heads, fixed head can be prevented outwards to be out of shape.Lead paper bag under described and be provided with the groove agreed with mutually with this back-up block shape, prevent back-up block from producing sidesway, back-up block upper end with on lead paper bag and contact.
The technical solution of the utility model, its beneficial effect is, adopts the back-up block of low cost to carry out the support of knife pivot of paper crusher, reduces costs and increases the intensity of cutter shaft, and can reduce cutter shaft and blade thus, reaching the effect that existing shredder is same.

Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the technical solution of the utility model is elaborated.
With reference to Fig. 1, Fig. 2, shown in Fig. 3, the paper shredder core of the present embodiment includes two cutter shafts 1, several set of blades 2 be arranged on cutter shaft, large side plate 3, little side plate 4, two pieces of fixed heads 5, on lead paper bag 6, under lead paper bag 7, back-up block 8 and motor 9 and gear drive 10, cutter shaft two ends are arranged on little side plate 3 respectively with on large side plate 4, two pieces of fixed heads 5 are connected between little side plate and large side plate, be positioned at the side of two cutter shafts, large side plate is provided with motor and gear drive, rotate to drive two cutter shafts, set of blades has cutter block cylindrical two set of blades to be separated and there is certain space, if set of blades itself is not with cutter ring cylindrical, plastic cement spacer can be increased separate between set of blades, to reach same object.
In order to strengthen the intensity of two cutter shafts when shredded paper, prevent the flexural deformation that cutter shaft rigidity produces not, a back-up block 8 is provided with between the sidepiece and fixed head of every bar cutter shaft, with reference to shown in Fig. 4, the structure of back-up block is provided with three support chips 81, each support chip is inserted between two groups of set of blades, support chip is provided with the recess 82 matched with cutter ring cylindrical or plastic cement spacer, support chip on back-up block withstands on the plastic cement spacer between the cutter ring cylindrical of cutter shaft or set of blades, and the rear end of back-up block is supported by fixed head.
For preventing the stressed generation distortion of fixed block, need to strengthen fixed block, by on lead paper bag and under lead paper bag and be all arranged between two fixed heads respectively, and by bolt 11 by lead paper bag and under lead paper bag and two fixed heads couple together, under lead paper bag and be provided with the groove agreed with mutually with this back-up block shape, prevent back-up block from producing sidesway, simultaneously back-up block upper end with on lead paper bag and contact, further back-up block is limited.
