The specific embodiment
A kind of food extrusion device shown in Fig. 3～4 has a framework 1, and its middle frame 1 comprises 11, one integral supports 12 of a base, and integral support 12 is made up of 2 side plates 121 and 1 top support 122.Integral support 12 whole erection are on base 11, and 2 side plates 121 are installed in parallel on the base 11, and top support 122 is installed between the inner surface on side plate 121 tops.
As Fig. 1～2 piston apparatus 3, it has a piston rod 31, and the lower bottom part of piston rod 31 is connected with circular piston 32, and piston rod 31 passes top support 122 and installs, and piston rod 31 drives the internal face slip of piston 32 along barrel 2.Piston rod 31 is connected with the driving gear 33 of two coaxial settings mutually, its direction of axis line of outside wall surface upper edge of piston rod 31 is provided with the tooth bar 311 that matches with driving gear 33, and tooth bar 311 is wholely set with piston rod 31.The modulus of a gear is greater than another one in these two driving gears 33, one in two driving gears 33 of tooth bar 311 and this is meshed, generally be with close-toothed driving tooth wheel and rack 311 engagements in extruding food process, what use for pick up speed in upper push-rod is driving tooth wheel and rack 311 engagement of big modulus, generally, a reduction box is set to reach the translational speed of control piston 32 here.Driving gear 33 is provided with the drive unit 34 that drives its rotation, and when small hand was operated, this drive unit was a turning handle usually, but common usefulness is motor in main equipment.
Shown in Fig. 5～6, in the utility model, tooth bar 311 is positioned at the middle part of piston rod 31, the upper end of piston rod 31, the bottom has one section last smooth department 312 and following smooth department 313 of joining with described tooth bar 311 respectively, when piston 32 is positioned at the lower bottom part of barrel 2, driving gear 33 is relative with following smooth department 313, when piston 32 is positioned at the top of barrel and during near top support 122, driving gear 33 is relative with last smooth department 312, be arranged so that like this working as piston 32 moves to before the high-low limit position, associated driving gear 33 falls into smooth department 312 or following smooth department 313, driving gear just is separated with tooth bar like this, thereby effectively prevented being moved further of piston 32, avoided piston 32 to clash into the parts that are positioned at its place ahead of advancing, and noise has also obtained effective control.
The top of piston rod 31 is equipped with nut 7, and piston rod 31 top ends are arranged with spring 5, and spring 5 is between the upper surface and nut 7 of top support 122.When to pressing down piston rod 31, spring 5 can be avoided the end face of nut 7 bump top supports 122, and can effectively stop tooth bar 311 to separate with driving gear 33 not mesh.The bottom of piston rod 31 is provided with cushion disk(-sc) 6, and cushion disk(-sc) 6 is circular, as the cylinder of plate or dish, is installed in the bottom of piston rod 31, the bottom of the bottom bump barrel 2 of so effective prevention piston rod 31.
Be arranged with sealing ring 8 on the outer circumference surface of piston 32, sealing ring 8 can prevent effectively that piston 32 is when pushing food downwards, and food is extruded from the gap between the internal face of piston 32 and barrel 2.
Piston 32 is generally to get loose with the bottom of piston rod 31 and is connected, and in actual mechanical process, when piston 32 tilted, piston 32 can self be regulated and make it be in the equilbrium position like this.
