Abstract
The utility model discloses a member for a kneading machine, comprising a member provided with a paper feed channel and a paper outlet channel. A hob kneading device is arranged between the paper feed channel and the paper outlet channel. The hob kneading device comprises two hob axles provided with a hob. The utility model is characterized in that a paper injection device is positioned below the paper outlet channel and a synchronous drive gear is positioned between the paper injection device and the hob kneading device. The utility model has the advantages that by positioning a paper injection device below the paper outlet channel and positioning a synchronous drive gear between the paper injection device and the hob kneading device, the paper injection device can discharge the crushed paper from the paper outlet channel compellingly at the same time while the hob rotates and crushes the paper. When the paper to be crushed once is too thick, the phenomenon as paper jam and paper dragging will not occur and the effect of paper crushing is ideal and the quantity of paper crushed is large. In addition, the machine seldom breaks down, therefore the service life of the kneading machine is dramatically prolonged.
Description

The utility model relates to a kind of shredder, especially relates to a kind of movement of shredder.
Background technology
The movement of shredder is the core component of shredder, the movement of existing shredder mainly by the core body that is provided with paper feed port and exit slot and be arranged on paper feed port and exit slot between the hobboing cutter paper shredder form.As disclosing a kind of electric shredder in No. 200420071230.9 Chinese utility model patents that on December 21st, 2005, bulletin was authorized, comprise body and paper box, body contains shell and thread hob paper shredder, the back upside of this thread hob paper shredder is provided with paper-advance unit, and described paper box tilts to be installed on the top of paper-advance unit; Described paper-advance unit comprises the spool of the band rubber wheel that is installed between the biside plate, paper platform is arranged below the spool, and the back of spool is obliquely installed backboard, and spool one end is installed train of reduction gears and paper feed motor; Also can have litter decoration and select the paper device.It can tear up the big heap file in the paper box of packing into successively automatically, and possesses highly confidential function, when the cover of paper box once cover the safety lock switch can auto lock till file all tears up, paper box face cover will be opened automatically after shredder is finished the work the several seconds, allow the next worker can handle shredded paper work, convenient easy-to-use, safe and secret, efficient is far above traditional shredder.But above-mentioned electric shredder is worked as disposable shredded paper number the most for a long time, phenomenons such as paperboard, holding paper, band paper occur through regular meeting, and not only the shredded paper effect is not ideal enough, and machine is broken down easily, reduces the life-span of shredder.
Summary of the invention
Technical problem to be solved in the utility model provides that a kind of shredded paper is satisfactory for result, shredded paper quantity is more, phenomenons such as paperboard, holding paper, band paper can not occur, and machine is difficult for sending out a back fault, can improve the movement of the shredder in shredder life-span.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of movement of shredder, comprise the core body that is provided with paper feed port and exit slot, be provided with the hobboing cutter paper shredder between described paper feed port and the described exit slot, described hobboing cutter paper shredder comprises two cutter shafts that are provided with hobboing cutter, be provided with paper injection mechanism behind the described exit slot, be provided with synchronous drive mechanism between described paper injection mechanism and the described hobboing cutter paper shredder.
Described paper injection mechanism comprises two coaxial paper carrying rolls that are arranged on the paper injection roll shaft, described synchronous drive mechanism comprises coaxial hobboing cutter gear and the coaxial paper injection gear that is arranged on described paper injection roll shaft one side that is arranged on described cutter shaft one side, and described hobboing cutter gear and described paper injection gear interconnect by at least one travelling gear.
The two ends of described paper carrying roll are provided with two swing arms, described paper injection roll shaft and described swing arm are coupling, be provided with elastics wing mechanism between described swing arm and the described core body, be set with the trace parallel between described two swing arms with described paper carrying roll.
Described elastics wing mechanism comprises and is arranged on swing arm spring between described swing arm and the described core body, and described core body is provided with deep-slotted chip breaker, and described paper injection roll shaft passes described deep-slotted chip breaker and described swing arm is coupling.
Can be coaxially arranged with the flexible paper injection roller shell made from the material of rubber and so on the described paper carrying roll.
Can be wholely set at least two segment blades on the described hobboing cutter, at this moment, the axle center of described cutter shaft must be less than the distance between the point of a knife of adjacent two segment blades to the distance in the axle center of described paper injection roll shaft.
Compared with prior art, advantage of the present utility model is by paper injection mechanism is set behind exit slot, and between paper injection mechanism and hobboing cutter paper shredder, synchronous drive mechanism is set, guaranteed when hobboing cutter rotates shredded paper, paper injection mechanism can force the shredded paper that comes out to enter in the paper shredding barrel from exit slot, when a shredded paper thickness is big, phenomenons such as paperboard, holding paper, band paper can not appear, shredded paper is satisfactory for result, shredded paper quantity is more, and machine is difficult for breaking down, and is therefore improved in the life-span of shredder greatly; Two swing arms are set at the two ends of paper carrying roll, the paper injection roll shaft is coupling in swing arm, elastics wing mechanism is set between swing arm and core body, and between two swing arms, fixedly install the trace parallel with paper carrying roll, can be when disposable shredded paper thickness be big, utilizing swing arm to drive paper carrying roll opens automatically, and the pulling force by the swing arm spring, make paper carrying roll keep the certain pressure of shredded paper is guaranteed the effect of paper injection, and after the shredded paper process finishes, can paper carrying roll be restored to the original state by the pulling force of swing arm spring again; Be arranged on the trace that walks abreast with paper carrying roll between two swing arms and then can keep the swing arm synchronization action at two ends, thereby two distances between the paper carrying roll are consistent on the each point axial along paper carrying roll; When hobboing cutter is when being wholely set the segment blade structure, the axle center that guarantees cutter shaft to the distance in the axle center of paper injection roll shaft less than the distance between the point of a knife of adjacent two segment blades; Can guarantee that before point of a knife thrusts paper paper carrying roll has been clamped the shredded paper that comes out from exit slot, make paper surface form tension force, help thrusting fully of point of a knife, avoid the generation of coil paper phenomenon.
