One magnetic torque Cao rotating head mechanism
Technical field
The utility model relates to spiral cover machinery apparatus field, especially a kind of magnetic torque Cao rotating head mechanism.
Background technology
Cap rotating machine is called again capsuling machine, capping machine or cover locking machine, be used for the bottle cap screwing after plastic bottle, glass bottle packing and unscrew equipment, be one of major equipment of automatic loading production line, Cao rotating head is the critical component of cap rotating mechanism, directly affects work efficiency and workmanship.Cao rotating head is carrying out spiral cover when operation, because the power of screwing is difficult to control to institute's torsion of applicable lid, easily causes lid to scratch, even damage.
Summary of the invention
The technical problems to be solved in the utility model is: in order to overcome the problem of above-mentioned middle existence, provide a kind of magnetic torque Cao rotating head mechanism, picked up clutch action by magnet Magnetic Phase, effectively protected lid, prevented that lid from scratching.
The utility model solves the technical scheme that its technical matters adopts: a kind of magnetic torque Cao rotating head mechanism, be used for being sleeved on Cao rotating head main driving axle, Cao rotating head main driving axle top is socketed with antifriction-bearing box and plunger tip cover successively, comprise be sleeved on Cao rotating head main driving axle outside lower clutch seat, be socketed in the upper Cao rotating head of lower clutch seat upper end and the upper clutch seat corresponding with lower clutch seat; Described antifriction-bearing box inlay card is between Cao rotating head main driving axle and lower clutch seat; Described lower clutch seat lower surface offers lower annular exterior notch, is stacked with successively lower annular gasket, lower suction sheet and lower friction lining in lower annular exterior notch; On described lower friction lining, offer lower annular groove, in lower annular groove, inlay card is provided with lower magnet; Described lower friction lining, lower suction sheet and lower annular gasket be by bolted in the lower annular exterior notch of lower clutch seat; Described upper clutch seat upper surface offers annular notches, is stacked with successively suction sheet and upper friction plate in upper annular notches; On described upper friction plate, offer annular groove, the interior inlay card of upper annular groove is provided with the upper magnet with the adhesive of lower magnet phase; Described upper suction sheet and upper friction plate be by bolted on upper clutch seat.
The outer cover of described upper clutch seat is equipped with protecting sleeve, and the top of protecting sleeve is coated on the outside of lower clutch seat.
Junction between described lower clutch seat and plunger tip cover is provided with circlip.
The beneficial effects of the utility model are: a kind of magnetic torque Cao rotating head mechanism, inhale principle by lower magnet and upper magnet Magnetic Phase, in the time that lid screws; reach certain moment of torsion, overcome the attractive force between lower magnet and upper magnet, play clutch action; effectively protection lid, prevents that lid from scratching.

Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, and basic structure of the present utility model is only described in a schematic way, and therefore it only shows the formation relevant with the utility model.
A kind of magnetic torque Cao rotating head mechanism as shown in Figure 1, be used for being sleeved on Cao rotating head main driving axle 1, Cao rotating head main driving axle 1 top is socketed with antifriction-bearing box 11 and plunger tip cover 12 successively, comprise be sleeved on Cao rotating head main driving axle 1 outside lower clutch seat 2, be socketed in the upper Cao rotating head 4 of lower clutch seat 2 upper ends and the upper clutch seat 3 corresponding with lower clutch seat 2; Described antifriction-bearing box 11 inlay cards are between Cao rotating head main driving axle 1 and lower clutch seat 2; Described lower clutch seat 2 lower surfaces offer lower annular exterior notch, are stacked with successively lower annular gasket 21, lower suction sheet 22 and lower friction lining 23 in lower annular exterior notch; On described lower friction lining 23, offer lower annular groove, in lower annular groove, inlay card is provided with lower magnet 24; Described lower friction lining 23, lower suction sheet 22 and lower annular gasket 21 be by bolted in the lower annular exterior notch of lower clutch seat 2; Described upper clutch seat 3 upper surfaces offer annular notches, are stacked with successively suction sheet 31 and upper friction plate 32 in upper annular notches; On described upper friction plate 32, offer annular groove, the interior inlay card of upper annular groove is provided with the upper magnet 33 with the adhesive of lower magnet phase; Described upper suction sheet 31 and upper friction plate 32 be by bolted on upper clutch seat.
The outer cover of described upper clutch seat 3 is equipped with protecting sleeve 5, and the top of protecting sleeve 5 is coated on the outside of lower clutch seat 2.
Junction between described lower clutch seat 2 and plunger tip cover 12 is provided with circlip 6.
A kind of magnetic torque Cao rotating head described in the utility model mechanism, inhales principles by lower magnet 24 and upper magnet 33 Magnetic Phases, in the time that lid screws; reach certain moment of torsion, overcome the attractive force between lower magnet 24 and upper magnet 33, play clutch action; effectively protection lid, prevents that lid from scratching.
Taking above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, relevant staff can, not departing from the scope of this utility model technological thought, carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on specification sheets, must determine its technical scope according to claim scope.
