Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for adjusting the supply amount of sticky raw materials such as butter cream.

Embodiments of the invention will be described with reference to the drawings.

1 is the hopper mounting bracket, 2 is the cylinder, 3 is the piston, 4 is the piston ring, 5 is the pump valve, 6 is the cylinder cap, 7 is the valve rotating arm, 8 is the rubber gasket, 9 is the nozzle mounting bracket, 10 is the nozzle. be.

The eccentric wheel adjustment boss 20 is fixed to the frame 20 and has an adjustment groove 2.
Attach the adjustment bolt 22 to the eccentric wheel adjustment boss 20 in which 1 is bored.
An eccentric wheel adjustment arm 19 is fixedly attached via the .

A drive shaft 23 passing through the centers of the eccentric wheel adjusting boss 20 and the eccentric wheel adjusting arm 19 is fixed to the eccentric inner ring 17 using a key.

The eccentric outer ring 16 is fitted into the eccentric inner ring 17, forming a rotating pair.

The cam rollers 18 fixed to both sides of the arms of the eccentric outer ring 16 are connected to the grooves 37 formed in the eccentric adjustment arm 19, and the cam rollers 24
are fitted into grooves 36 bored in the S-shaped stroke lever 14, respectively.

The lower end of the S-shaped stroke arm 14 is connected to a stroke arm holder 25.
The stroke adjustment shaft 27, quantity adjustment arm 28, cam roller 29, quantity adjustment arm 30, stop pin 31, cam roller 34, quantity adjustment knob 32, quantity adjustment shaft 33, adjustment handle are connected by a stroke stopper pin 26. A series of portion adjustment mechanisms consisting of wheels 35 allow for rocking back and forth.

On the other hand, above the groove 36 formed in the S-shaped stroke arm 14, there is a cam roller 1 fixed to the piston drive shaft collar 13.
5 is fitted, and is connected to the piston 3 via the piston drive shaft collar 13, piston rod 11, and set pin 12.

When the drive shaft 23 performs a rotational movement, the eccentric inner ring 17, which is integrated with the drive shaft 23 through a key, also rotates at the same time.

Misalignment between the center of rotation of the eccentric inner ring 170 and the center of the eccentric outer ring 16,
and a cam roller 18 fixed to the arm of the eccentric outer ring 16
is fitted into the groove 37 formed in the eccentric wheel adjustment arm 19, so that the eccentric outer ring 16 performs a restrained vertical reciprocating motion.

When the eccentric outer ring 16 performs vertical reciprocating motion restrained by the groove 37, the cam roller 24 moves into the S-shaped stroke arm 14.
The S-shaped stroke stopper 14 performs a swinging motion about the S-shaped stroke stopper pin 26.

Further, by the cam roller 15 fixed to the piston drive shaft collar 13, the swinging motion of the S-shaped stroke arm 14 is transmitted to the piston 3 as a back and forth reciprocating motion.

In the present invention, from the adjustment handle ring 35 to the amount adjustment arm 28
By utilizing the series of fine quantity adjustment mechanisms described above, and by freely changing the inclination of the eccentric wheel adjustment arm 19 using the adjustment groove 21 and adjustment bolt 22, an S-shaped stroke lever with the stroke locking pin 26 as a fulcrum is created. By changing the size of the swing angle range of the cam roller 14, the stroke amount of the back and forth reciprocating motion transmitted to the cam roller 15 can be adjusted to be large or small.

Further, since the S-shaped stroke lever is used, the transmission from the cam roller 24 to the cam roller 15 can be performed more effectively and smoothly than when a linear stroke lever is used.

Although the present invention utilizes a series of portion fine adjustment mechanisms from the adjustment handle ring 35 to the portion adjustment arm 28, the main feature is an eccentric ring and an eccentric ring that can expand or reduce the portion fine adjustment range depending on the application. This is due to the use of a continuous quantity adjustment mechanism using an adjustment arm and the use of an S-shaped stroke lever to ensure effective and smooth transmission.
