2. When the piston 3 is driven by the main shaft 2 to rotate to the plane section AB to be in contact with the piston seat 4, the piston 3 does not move back and forth relative to the main shaft 2 and only rotates in situ, at this time, the circular arc surface M on the peripheral wall of the piston 3 is used as a feeding door to just seal the feeding hole 6 on the shell 15, so that the material is prevented from reversely flowing from the feeding hole when the material is pushed next.

3. The piston 3 continues to rotate, the contact position of the spiral section of the piston 3 and the piston seat 4 is changed from the foremost end B to the rearmost end C, at this time, the piston 3 is in contact with the rearmost end D of the spiral section on the piston seat, and the piston 3 is pushed forward along the main shaft under the pushing of the elastic force of the spring 7, so that the meat emulsion is conveyed forward.

The ball forming unit comprises a small piston 9, a piston rod 10, a small spring 11, a piston disc 12, a gear ring 13 and a fixed seat 14. The fixed seat 14 and the inner gear ring 16 are fixed, the gear ring 13 is sleeved in a hole on the piston disc 12, the piston disc 12 drives the piston rod 10 to rotate, the piston rod 10 is sleeved at the tail end of the small piston 9 and positioned by the fixed seat, and the small piston 9 is sleeved on the inner surface of the gear ring 13 and driven by the gear ring 13 to rotate. The main shaft 2 drives the driving wheel 5 to rotate, the driving wheel 5 drives the ball forming unit to rotate, and different working stations are switched to finish different working procedures such as extrusion, forming, correction, extrusion, demoulding and the like. The ball forming process is as follows:

when the concave arc cavity at one end of the small piston 9 of the first ball forming unit is filled with food such as meat emulsion, the small piston 9 and the piston rod 10 overcome the elastic force of the small spring 11 and are coupled with the driving wheel 5, the driving wheel 5 drives the ball forming unit to rotate, and the ball forming unit rotates from the station 1 to the station 2. Meanwhile, the second ball forming unit enters a station 1, when the small piston of the second ball forming unit is full of meat emulsion, the second ball forming unit is turned to the next station, and the first ball forming unit is turned to one station again. In this process, the gear ring 13 of the first ball forming unit is engaged with the ring gear 16 provided on the inner wall of the fixing base 14.

Since the ring gear 16 is fixed to the fixed base 14, it cannot move. The ball forming units rotate, at this time, the gear ring 13 of the first ball forming unit starts to rotate under the action of the ring gear 16 to drive the small piston 9 to rotate, the initially formed balls in the concave circular arc cavity of the small piston 9 rotate relative to the shell, and the concave circular arc curved surface (the concave circular arc curved surface is arranged on the inner side of the shell from the 2# station to the 4# station) arranged on the inner side of the shell corrects the initially formed balls into a regular spherical body.

In order to save energy and reduce unnecessary power of the product, the inner gear ring 16 is only provided with partial inner teeth, and the inner gear ring drives the small piston 9 to rotate only when needed.

3.1 # small piston 9 rotates to 2# station, shoulder 101 of 1# piston rod 10 contacts with boss S1 of fixing base 14 bottom surface, and as shown in fig. 10-12, boss S1 promotes 1# small piston 9 to move backward a certain distance for 1# small piston 9 breaks away from drive wheel 5, thereby first ball forming unit stops rotating. The next ball forming unit enters the station # 1 at this time.

4. After the next ball forming unit is filled with meat emulsion at the station # 1, a piston rod of the ball forming unit is coupled with a drive 5, and the drive wheel 5 drives the ball forming unit to rotate by one station. And the first ball forming unit at the station 2# rotates towards the station 3#, and in the rotating process, the top end 102 of the piston rod 10 of the first ball forming unit is contacted with the inclined convex surface S2 of the fixed seat 14, so that the small piston 9 of the first ball forming unit pushes out the primarily formed meat balls.

5. The gear ring 13 of the first ball forming unit rotates with irregular meat balls under the action of the fixed annular gear 16 while the first ball forming unit rotates from the station # 2 to the station # 3. The autorotation meat balls are gradually corrected into regular spherical bodies under the action of the concave circular arc curved surface 17 arranged on the inner side of the shell 15.

6. At station 3# the meat balls of the first ball forming unit have been completely pushed out by the small piston 9 and the forming has been completed. But at this time the meat balls have not been separated from the area of the concave circular arc surface 17 provided on the inner side of the housing, the bottom of the meat balls is adhered to the top of the small piston 9, and the top of the meat balls is in contact with the top surface of the concave circular arc surface 17 on the inner side of the housing.

7. From the station 3 to the station 4, the process of separating the meatballs from the concave circular arc curved surface 17 of the first ball forming unit, in this process, the meatballs adhered to the small piston 9 are pulled backwards under the friction force of the top of the concave circular arc curved surface on the inner side of the shell, so that the adhesion force between the meatballs and the small piston 9 is basically lost. At this point, the small piston 9 brings the pellets with less firm adhesion into the station # 4.

8. With the continuous shaping of the meatballs of the following station, the latter ball shaping unit is rotated forward, the meatballs of the station 4 are also rotated forward, and when the station 4 starts to rotate, the first ball shaping unit moves from a static state, inertia causes the meatballs to thoroughly separate from the small piston 9 and drop into the tray below. The whole shaping process of one meat ball is completed.
