In above-mentioned technical proposal, it is preferred that the eccentric wheel has an eccentric orfice, and the driving shaft exists through setting
In the eccentric orfice.
In above-mentioned technical proposal, it is preferred that the driving shaft is mutually fixed with the eccentric wheel by spline.
In above-mentioned technical proposal, it is preferred that offer oil groove on the excircle wall surface of the eccentric wheel.
In above-mentioned technical proposal, it is preferred that the axial line of the driven shaft is parallel with the axial line of the driving shaft.
In above-mentioned technical proposal, it is preferred that between the both ends of the driven shaft and the described lifting seat, the driving shaft
Angular contact ball bearing is mounted between both ends and the rack.
In above-mentioned technical proposal, it is preferred that be fixedly installed motor fixing seat, the decelerating motor in the rack
It is mounted in the motor fixing seat.
The utility model obtains compared with prior art following the utility model has the advantages that this case drives bias by setting decelerating motor
The structure of wheel drives eccentric wheel rotation by decelerating motor, and the every rotation of eccentric wheel one week can drive lifting seat to complete one upwards
Secondary lifting movement, and eccentric wheel is contacted with the driven shaft rolling friction on lifting seat always, and the continuity of lifting is preferable, comes back
The movement of mechanism new line more uniformly, is lifted more efficient.

Specific embodiment
By the technology contents of utility model are described in detail, construction feature, are reached purpose and efficacy, below in conjunction with implementation
Example simultaneously cooperates attached drawing to be described in detail.
The blow moulding machine eccentric wheel type head raising device 100 of this case includes lifting mechanism 1 and lifting seat 2.Below in conjunction with attached
Fig. 1~attached drawing 4 illustrates each structure composition and its working principle.Overlying relation described in the present embodiment and attached drawing 2
Shown in head raising device positional relationship it is corresponding.
As shown in Fig. 1, lifting mechanism 1 includes rack 11, the driving shaft 12 being rotatably arranged in rack 11, fixed peace
Eccentric wheel 13 on driving shaft 12 is fixed in rack 11 and the decelerating motor with the transmission connection of 12 phase of driving shaft
14.Lifting seat 2 is located at the surface of eccentric wheel 13, is provided with driven shaft 21 with being lifted the lower rotation of seat 2, driven shaft 21 with it is inclined
13 rolling friction of heart wheel contact.Motor fixing seat 141 is fixedly installed in rack 11, decelerating motor 14 is mounted on motor fixing seat
On 141.Since the excircle wall surface of eccentric wheel 13 is contacted with 21 rolling friction of driven shaft, in order to reduce the loss of this friction,
Oil groove 132 is offered on the excircle wall surface of eccentric wheel 13, lubricating oil or lubricant can be added by this oil groove 132, so that two
The contact surface of person is more smooth during lifting.
As shown in 2~attached drawing of attached drawing 3, the axial line of driven shaft 21 is parallel with the axial line of driving shaft 12.Driven shaft 21
Both ends and lifting seat 2 between, between the both ends of driving shaft 12 and rack 11 be mounted on angular contact ball bearing 3, be in this way for
When eccentric wheel rotates and lifting seat 2 is driven to move up and down, driving shaft 12 and driven shaft 21 can be respectively balancedly by diameters
To the power with axial direction, enhance the stability of lifting apparatus.Specifically, being lifted seat 2 when decelerating motor 14 drives eccentric wheel 13 to rotate
Opposite rack 11 moves up and down along a straight line, realizes lifting movement.
As shown in Fig. 4, eccentric wheel 13 has an eccentric orfice 131, and driving shaft 12, which runs through, to be arranged in eccentric orfice 131, and
And driving shaft 12 is fixed with eccentric wheel 13 by 15 phase of spline.
The working principle of the blow moulding machine eccentric wheel type head raising device 100 of this case are as follows: decelerating motor 14 operates, and drives driving shaft
12 and eccentric wheel 13 rotate, eccentric wheel 13 contacts with 21 rolling friction of driven shaft, and the every rotation of eccentric wheel 13 one week, realization is lifted seat
Lifting is primary upwards for 2 opposite racks 11, completes new line function, and the excircle wall surface of eccentric wheel 13 is rolled with driven shaft 21 always
Dynamic friction contact, the continuity of lifting movement is preferable, lifting is more efficient.
The above embodiments are only for explaining the technical ideas and features of the present invention, and its object is to allow be familiar with technique
