Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wrapped dumplings, in particular to a continuous official hat dumpling full-automatic wrapping and tray loading system. BACKGROUND

[0002] Dumplings are a kind of traditional Chinese food with relatively complex production. For a long time, this traditional food mainly relies on manual wrapping and tray loading, and the operation efficiency is low. In recent years, some automatic wrapping technologies for dumplings have been proposed, but they all cut the dough first and then fill the stuffing, and then use a mechanical method to simulate manual wrapping to achieve wrapping. In this way, the dough is transported independently between each station, and the stability and reliability are not high. SUMMARY

[0003] In order to solve the problems of low wrapping efficiency and poor stability of the official hat dumpling, the present application provides a continuous official hat dumpling full-automatic wrapping and tray loading system, which can realize automatic wrapping of official hat dumplings, improve efficiency and stability.

[0004] The technical scheme is as follows: a continuous official hat dumpling full-automatic wrapping and tray loading system, characterized in that it comprises a dough rolling station, a stuffing filling station, a dough folding station, a dough edge pinching station, a dough arc edge die cutting station, a dough edge folding station, a dumpling curling and pinching station, and a traction device arranged in sequence. The dumpling curling and pinching station is provided below a tray loading station. A first conveying belt is arranged between the dough rolling station and the stuffing filling station. A second conveying belt is arranged at the dough edge pinching station, the dough arc edge die cutting station, and the dough edge folding station. A shearing device is arranged at the dumpling curling and pinching station. The dough is continuously rolled to a certain thickness at the dough rolling station and is transmitted to the stuffing filling station by the first conveying belt. The dumpling is continuously formed from the dough rolling station to the dumpling curling and pinching station. After being cut into individual dumplings by the shearing device, the dumplings enter the tray loading station.

[0005] Further, the dough is continuously rolled to a certain thickness at the dough rolling station and is transmitted to the stuffing filling station by the first conveying belt.

[0006] The stuffing filling station quantitatively extrudes the stuffing and places it on the continuous dough at a fixed interval.

[0007] The dough folding station is a pair of vertical guide plates in the shape of a converging opening. The minimum gap between the two vertical guide plates is not greater than twice the thickness of the dough and extends to the end of the second conveying belt. The long strip-shaped dough is folded in half by the vertical guide plates and the stuffing is wrapped therein.

[0008] The dough edge pinching station is a pair of spaced rollers. The gap between the two rollers is less than twice the thickness of the dough. The top edge of the folded dough is pinched by the rollers.

[0009] The dough edge die-cutting station consists of a pair of die-cutting blades connected to a cutting cylinder, which cut the top edge of the dough into the shape of a wonton edge.

[0010] The height of the vertical guide plate at the dough-flipping station is reduced, and one of the vertical baffles has a folding strip at the top. After passing the folding strip, the top edge of the dough is flipped to one side to form a continuous wonton blank.

[0011] The wonton rolling and kneading station includes a fixed rod and two movable rods. One of the movable rods is connected to a lower gear, and the other movable rod is connected to an upper gear via a lifting cylinder. The traction device includes a traction gripper connected to the traction cylinder. The traction gripper pulls the continuous wonton blanks to the length of a wonton. The wonton blanks pass between a fixed rod and the two movable rods. Then, the two movable rods clamp the end faces of the continuous wonton blanks and roll them into a wonton shape around the movable rod connected to the lower gear. The fixed rod then clamps the rolls again, and the lifting cylinder drives the movable rods to pull them out. Finally, the shearing device cuts the continuous wonton blanks to form a single wonton with the bottom facing up.

[0012] The pallet loading station includes a pallet conveying system consisting of a pallet rack, a longitudinal conveyor belt, a transverse conveyor belt, a pallet hopper, and a discharge conveyor belt. The pallet conveying system includes two sets. When one set of pallet conveying system is loading, the other set of pallet conveying system completes the full pallet discharge and empty pallet grabbing, and waits for the first set of pallet conveying system to be filled with wontons before taking over its loading work. At the same time, the first set of pallet conveying system performs full pallet discharge and empty pallet grabbing.

[0013] The pallet is placed in the pallet rack, which is fixed to the longitudinal conveyor belt. The longitudinal conveyor belt is fixed to the transverse conveyor belt. The longitudinal and transverse conveyor belts can drive the pallet to be positioned in any plane to adjust the pit in the pallet to align with the wonton forming station. The pallet rack can move under the pallet hopper driven by the longitudinal and transverse conveyor belts and grab an empty pallet from the pallet hopper. The pallet rack can move above the discharge conveyor belt driven by the longitudinal and transverse conveyor belts and place the pallet full of wontons on the discharge conveyor belt to complete the discharge.

[0014] By adopting this invention, the entire process of making wontons—from dough rolling, filling, and wrapping—is fully automated. This is achieved through a series of stations: dough rolling, filling, dough folding, dough edge pinching, dough edge die-cutting, dough edge turning, wonton rolling and pinching, and a traction device. The dough is continuously conveyed before the wontons are formed, and after being cut into individual pieces, they are taken out by the loading station. The posture can be stably controlled, thus realizing the automatic wrapping of "official hat" wontons and improving efficiency and stability. Attached Figure Description

[0022] As shown in the figure, a continuous fully automatic wrapping and loading system for wontons is characterized by comprising a dough rolling station 1, a filling station 2, a dough folding station 3, a dough edge pinching station 4, a dough arc edge die-cutting station 5, a dough edge turning station 6, a wonton rolling and pinching station 7, and a traction device 8 arranged sequentially. A loading station 9 is provided below the wonton rolling and pinching station 7. A first conveyor belt 10 is provided between the dough rolling station 1 and the filling station 2. The dough is continuously rolled and pressed by the dough rolling station 1 to a dough sheet 11 of a certain thickness, and then transported by the first conveyor belt 10 to the filling station 2. The filling station 2 extrudes a quantitative amount of filling 12 and places it on the continuous dough sheet 11 at fixed intervals. The equipment of the dough rolling station 1 and the filling station 2 is commercially available equipment.

[0023] The dough edge pinching station 4, the dough arc edge die-cutting station 5, and the dough folding station 6 are equipped with a second conveyor belt 13; the dough folding station 3 is a pair of vertical guide plates with a constricted opening. The minimum gap between the two vertical guide plates is no more than twice the thickness of the dough 11 and extends to the end of the second conveyor belt 13. The dough 11 passes through the vertical guide plates, folds the long strip of dough in half, and wraps the filling 12 inside.

[0024] The dough edge pinching station 4 consists of a pair of spaced rollers with a gap between them less than twice the thickness of the dough 11. The dough 11 passes through the rollers to pinch the top edge of the folded dough together, simulating manual pinching of the dough 11 together.

[0025] The dough edge die-cutting station 5 consists of a pair of die-cutting blades connected to the edge-cutting cylinder. The die-cutting blades cut the top edge of the dough 11 into the shape of the wonton edge. Since the dough is long and needs to be shaped, when wrapping by hand, the corresponding tube cap wonton wrapper can be selected directly.

[0026] At station 6, the height of the vertical guide plate is reduced and one of the vertical baffles has a folding strip on the top. After the top edge of the dough passes through the folding strip, it is folded to one side to form a continuous wonton blank. The wonton is initially formed and can then be cut.

[0027] The wonton rolling and pinching station is equipped with a shearing device 14 at 7 locations. The wonton dough is continuously formed from the dough rolling station to the wonton rolling and pinching station. After being cut into individual wontons by the shearing device 14, the wontons enter the loading station.

[0028] Before cutting, the wontons need to be rolled and shaped.

[0029] The wonton rolling and kneading station 7 includes a fixed rod 15 and two movable rods 16 and 17. One movable rod 16 is connected to the lower gear 18, and the other movable rod 17 is connected to the upper gear 20 through the lifting cylinder 19. The traction device 8 includes a traction gripper connected to the traction cylinder. The traction gripper pulls the continuous wonton blanks to the length of a wonton. The wonton blank passes between the fixed rod 15 and the two movable rods 16 and 17. The traction device 8 stops after being stretched to the desired position. The lower gear 18 and the upper gear 20 are driven synchronously by a rack to achieve rotation. The movable rod 16 is installed at the eccentric position of the lower gear 18, and the movable rod 17 is installed at the eccentric position of the upper gear 20. Then, the two movable rods 16 and 17 clamp the end face of the continuous wonton blank and roll it into a wonton shape around the movable rod 16 connected to the lower gear 18. The fixed rod 15 then clamps it, and the lifting cylinder 19 drives the movable rod 17 to be pulled out. Finally, the shearing device 14 cuts the continuous wonton blank to form a single wonton with the bottom facing up.

[0030] The pallet loading station includes a pallet conveying system consisting of a pallet rack, a longitudinal conveyor belt, a transverse conveyor belt, a pallet hopper, and a discharge conveyor belt. The pallet conveying system consists of two sets. When one set of pallet conveying system is loading, the other set of pallet conveying system completes the discharge of full pallets and the grabbing of empty pallets, and waits for the first set of pallet conveying system to be filled with wontons before taking over its loading work. At the same time, the first set of pallet conveying system performs the discharge of full pallets and the grabbing of empty pallets.

[0031] The pallet is placed in the pallet frame 21, which is fixed on the longitudinal conveyor belt 22 and the transverse conveyor belt 23. The longitudinal conveyor belt 22 and the transverse conveyor belt 23 can drive the pallet to be positioned on any plane to adjust the pit in the pallet 24 to align with the wonton forming station. The pallet frame 21 can move under the pallet hopper 25 driven by the longitudinal and transverse conveyor belts and grab an empty pallet from the pallet hopper 25. The pallet frame 21 can move above the discharge conveyor belt 24 driven by the longitudinal conveyor belt 22 and the transverse conveyor belt 23 and place the pallet full of wontons on the discharge conveyor belt 24 to complete the discharge.
