[0062] It should be noted that the pinching and forming mechanism 5 is a well-known device, such as the food forming device disclosed in Chinese Patent No. 201821300430.5, and will not be described in detail.

[0063] Working principle of the present invention:

[0064] 1. If Figure 1 , Figure 3 As shown, leather materials and filling materials are added to the two hoppers 10 respectively, and the two quantitative feeding mechanisms 2 are fed respectively through the two hoppers 10. The feeding motor 26 drives the rotating head 23 to rotate through the feeding gear set 26, thereby driving the feeding blade 25 to rotate. Since the outer edge of the feeding blade 25 is tangent to the wall of the barrel cavity 211 of the feeding barrel 21 due to the action of centrifugal force, the feeding blade 25 can move radially along the rotating head 23 under the drive of the wall of the barrel cavity 211 of the feeding barrel 21, pushing the leather material or filling material to the discharge port 213 of the feeding barrel 21 and entering the central material guiding mechanism 3 through the discharge port 213.

[0065] 2. If Fig. 9 , Fig.10 As shown, the leather material and the filling material enter the annular outer cavity 324 and the barrel-shaped inner cavity 325 of the material guiding barrel 32 respectively from the first feeding port 321 and the second feeding port 322 of the material guiding barrel 32 of the central material guiding mechanism 3. When the leather material from the annular outer cavity 324 flows through the material guiding ring 33, the pressing sheet 333 on the material guiding ring 33 squeezes the leather material downward, so that the leather material enters the lower port of the material guiding barrel 32. At the same time, the filling material from the barrel-shaped inner cavity 325 falls at the center of the leather material, so that the leather material and the filling material are conveyed separately, and then the leather material wraps the filling material.

[0066] 3. If Fig.12 , Fig.13 As shown, the cooling motor 42 on the head cooling mechanism 4 drives the annular gear seat 44 to rotate rapidly through the cooling gear set 43, thereby driving the guide ring 33 on the central guide mechanism 3 to rotate rapidly. At the same time, cooling water enters the water channel 411 from the water inlet 443 on the annular gear seat 44 and flows out from the water outlet 442, taking away the heat generated by the rotation of the annular gear seat 44 and keeping the temperature of the annular gear seat 44 at a low state.

[0067] 4. If Fig.16 , Fig.17 As shown, the material receiving motor 71 on the transmission material receiving mechanism 7 drives the forming lifting cam 73 and the conveyor belt lifting cam 75 to move simultaneously through the material receiving diverter 72, and the forming lifting cam 73 drives the pinching and forming mechanism 5 to move up and down through the lifting rod 74, and the conveyor belt lifting cam 75 resting on the conveyor belt connecting rod mechanism 76 drives the conveyor belt connecting rod mechanism 76 to swing back and forth, thereby driving the top of the conveyor belt 6 installed on the conveyor belt connecting rod mechanism 76 to move up and down, forming two working states in which the pinching and forming mechanism 5 and the conveyor belt 6 are in contact with each other and away from each other. After the pinching and forming mechanism 5 forms the buns, the conveyor belt 6 and the pinching and forming mechanism 5 are in contact with each other to receive the buns dropped from the pinching and forming mechanism 5, so as to avoid deformation caused by the falling of the buns.

[0068] 5. Reference Figure 1 , Fig.10 As shown, when it is necessary to produce steamed buns with multiple fillings, that is, steamed buns with fillings within fillings, the upper cover 31 of the central material guiding mechanism 3 can be opened, and the solid filling supply mechanism 8 or the soft filling supply mechanism 9 can directly supply materials to the barrel-shaped inner cavity 325 of the material guide barrel 32, so as to facilitate the direct delivery of the solid filling or soft filling into the center of the filling, thereby realizing steamed buns with fillings within fillings.
