CN2736156Y - Power transmitting means of plastic pneumatic thermoforming machine - Google Patents

Abstract

The utility model provides a power transmitting device of the plastic pneumatic thermoforming machine, comprising a support seat for the machine frame, a main shaft and a transmission case. The main shaft is arranged in the bearing seat of the support seat for the machine frame. The output end of the transmission case is coaxial with the main shaft. With the adoption of the structure, the main shaft is coaxial with the dynamic force output end of the transmission case, and the rotation of the main shaft is directly driven. Such mode gets rid of the disadvantage of uneven stress to the chain. So the shock is reduced and the noise is decreased during the operation of the machine. The service life of the main shaft is prolonged simultaneously.

Description

The actuating unit of Pneumatic hot plastic molding machine

Technical field

The utility model relates to a kind of Pneumatic hot plastic molding machine, refers in particular to a kind of actuating unit of Pneumatic hot plastic molding machine.

Background technology

Thereby the power of Pneumatic hot plastic molding machine generally all is to drive the work of main frame main shaft by gearbox by chain drive at present.Because the moulding of make-up machine action is clearance-type motion, the impulsive force to main shaft during work is very big, thereby causes the driving chain unbalance stress, makes machine produce very big vibrations and noise, and the life-span of chain is reduced greatly.In addition, for vibrations and the noise that reduces machine, be provided with vibration abatement at an end of main shaft, complicated machine construction has increased manufacturing cost, has brought inconvenience for simultaneously the maintenance and repair of machine.On the other hand, owing to adopt chain drive between main shaft and the gearbox, the rotating speed between the two that makes can not be controlled accurately, has influenced the crudy of product, has caused unnecessary waste.

The utility model content

The purpose of this utility model is to provide a kind of actuating unit of Pneumatic hot plastic molding machine, has the advantages that transmission shakes less, noise is low.

For achieving the above object, the utility model adopts following technical proposals to realize:

A kind of actuating unit of Pneumatic hot plastic molding machine comprises main frame supporting seat, main shaft and gearbox, and wherein main shaft is arranged in the bearing block on the main frame supporting seat, and it is characterized in that: gear box output end and main shaft are coaxial.

By adopting said structure, the clutch end of main shaft and gearbox is coaxial, directly drives the rotation of main shaft.Such mode has been abandoned the shortcoming of chain unbalance stress, can reduce vibrations so that host work the time, and noise-decreasing has prolonged service life of main shaft simultaneously.

Description of drawings

Fig. 1 is a background technology structural representation of the present utility model;

Fig. 2 is the utility model structural representation.

The specific embodiment

As shown in Figure 1, be to utilize gearbox 1 to drive the mode that main shaft 3 rotates in the background technology by chain 2, main shaft 3 is arranged on the bearing block 5 of main frame supporting seat 4, chain 2 is set in an end of main shaft 3, and connect simultaneously gearbox 1 clutch end the axle 11, the other end at main shaft 3 is provided with shockproof main shaft distance bushing 31, it is powerdriven the time, because the moulding of make-up machine action is clearance-type motion, impulsive force to main shaft 3 during work is very big, thereby cause driving chain 2 unbalance stress, make machine produce very big vibrations and noise, the life-span of chain 2 is reduced greatly.Can follow very big vibrations and noise, and need prevent vibrations by sheathed axle sleeve 31 on main shaft 3, structure is cumbersome, and vibrations have simultaneously also reduced the service life of main shaft 3 on the main frame.

As shown in Figure 2, a kind of actuating unit of Pneumatic hot plastic molding machine comprises main frame supporting seat 4, main shaft 3 and gearbox 1, and wherein main shaft 3 is arranged in the bearing block 5 on the main frame supporting seat 4, and gearbox 1 output and main shaft 3 are coaxial.By adopting said structure, gearbox 1 output and main shaft 3 are coaxial, and gearbox 1 output directly drives the rotation of main shaft 3, thereby drive the motion of stabilizer in the main frame.Such mode can reduce vibrations so that host work the time, and noise-decreasing has prolonged service life of main shaft 3 simultaneously.
