Description
Technical field
The utility model relates to a kind of tea twisting machine, refers in particular to a kind of pressue device of tea twisting machine.
Background technology
Tea twisting machine is the machinery of kneading operation in primary processing of tea process for completing, the main purpose of wherein kneading is blade to roll tightly slivering rope, be beneficial to drying and moulding, suitable destruction is also organized simultaneously, extrude a part of tea juice, make dry tea easily brew out juice, there is again certain resistance to bubble, improve consumption value.
The operation principle of kneading machine depends on manual kneading, and updating of product, belongs to one of comparatively ripe mechanical type in tea manufacturing machine industry thereupon; General kneading machine mainly comprises: pressing mechanism and the blanking device of frame, rub barrel and power drive mechanism thereof, the kneading disk that is arranged on rub barrel below, control gland pressure; Wherein the parts of core are rub barrel and kneading disk, both relative motions (be generally rub barrel and take platen running, kneading disk is motionless) complete the kneading of tealeaves, and existing kneading machine mainly comprises: open side type kneading machine and queen post kneading machine, both pressuring methods are different, and respectively have its pluses and minuses.
(1), the pressue device of open side type kneading machine, by a column, be fixed on frame edge, by curved frame one end and column pivot bush unit and both, be worm drive, nut and corresponding screw rod are set in column, and curved frame is fixedly connected with this nut, the loose slot corresponding with link is set on column, and the bottom of screw rod arranges corresponding with it active handwheel arm; The other end of curved frame is connected with platen by connecting rod; By driving handwheel arm, make the platen that is connected in curved frame realize the pressurization that moves up and down, simultaneously in the process of rub barrel motion, when kneading disk is kneaded tealeaves, tealeaves rolls and drives platen in the rotation of rub barrel inwall, makes to knead action and is more tending towards kneading by hand.
The shortcoming that main existence is set like this: fixing of open side type is stable not, the rigidity of column is not enough, once produce, causes platen not work normally, thereby affects kneading of tealeaves; The curved frame of while open side type can realize 360 ° and rotate freely, when filler, need in rub barrel, by handwheel arm, shift out platen, now platen and rub barrel inwall are in contact condition, there is certain frictional force between the two, and the required power of handwheel arm is also just larger, under manual state, be difficult to realize operation.
(2), the pressue device of queen post kneading machine, its structure moves up and down for controlling platen by the mode of worm drive, the screw rod of worm drive is fixedly connected with platen, nut is radially fixedly connected on gamp toothholder, by cone pinion, drive gamp toothholder to rotate, thus the motion of the upper-lower position of drive screw; Curved frame center arranges sleeve, screw rod is positioned at sleeve, in order to prevent that screw rod and nut are due to rocking that fit clearance causes, outside the rub barrel of frame, two ends arrange respectively 2 pillars, and curved frame is movably hinged with a pillar wherein, and locking mechanism is set on another pillar completes fixing to curved frame, on curved frame two ends, the guide rod on corresponding vertical direction is set simultaneously, platen is fixed in guide rod one end, the other end and curved frame pivot bush unit, realize a plurality of vertical axes to location.It is even that queen post screw pressurizing device has lifting with respect to open side type, and lifting intensity is less.
The location that is provided for platen and the lifting of guide rod, but when kneading operation, platen is due to the setting of guide rod, platen vertically applies pressure to machined surface in stationary state, can not be rotated, such motion mode is inconsistent with kneading technique, because in the process of kneading, tealeaves upper-lower position stressing conditions in rub barrel is different, upper end tealeaves part because contact with gland and and gland between produce to rub and occurred vibration, bottom tealeaves is owing to contacting and having produced rolling with kneading disk, rotation, now be unfavorable for the shaping (agglomerating) of upper end tealeaves, if platen pressure is crossed conference and is produced killing of tea group, thereby there is flat tea, fannings etc. run tea phenomenon, affect the quality of tealeaves.
