[0001] The invention relates to the technical field of food packaging production, in particular to a fully automatic production process for folding and forming rice dumplings leaves and bundling rice dumplings with four corners. Background Art

[0002] The production of traditional four-corner zongzi is mainly done manually, specifically by taking two pieces of zong leaves and stacking them in an offset manner, rotating them at one-third of the way to form a cone, putting in glutinous rice and stuffing, folding them again to seal the top, and finally tying them with ropes. This manual operation is labor-intensive and cannot meet the needs of mass production. For automated production, due to the soft material characteristics of zong leaves, it is difficult to form them, and reliability is difficult to ensure, which can easily lead to incomplete forming and leakage.

DETAILED DESCRIPTION

[0038] The specific structure and working process of the present invention are as follows:

[0039] like Figure 1-Figure 5As shown, a specific implementation mode of the present invention includes a double-track annular conveyor line 1, a supporting mechanism 2, a rice dumpling leaf conveyor line 3, a forming mechanism 4, a filling mechanism 5, a capping mechanism 6, and a bundling mechanism 7.

[0040] The slider on the double-track circular conveyor line 1 is connected to the transport plate 206 on the supporting mechanism 2, and the supporting mechanism 2 is transported to the rice dumpling leaf conveyor line 3, the forming mechanism 4, the filling mechanism 5, the capping mechanism 6 and the bundling mechanism 7 in sequence through chain transmission;

[0041] When the supporting mechanism 2 is located at the zongzi leaf forming station. The arranged zongzi leaves are on the zongzi leaf conveyor line 3, and are conveyed to the leaf shifting clamp 302 by the zongzi leaf conveyor belt 301. When the zongzi leaves completely enter the leaf shifting clamp 302, the zongzi leaves are clamped by the zongzi leaves and first translated for a distance and then rotated 90°, and the zongzi leaves are cut on the side of the zongzi-shaped mold 402, and the bottom edge of the zongzi leaves exceeds the bottom of the zongzi-shaped mold 402 by about 10 mm. Because the symmetry plane of the zongzi-shaped mold 402 and the symmetry plane of the zongzi leaf conveyor belt 301 are offset by one-sixth, the zongzi leaves will fit with the zongzi-shaped mold 402 at about one-third; then, the positive angle support 201 on the supporting mechanism 2 presses the zongzi leaves onto the zongzi-shaped mold 402, and the leaf shifting clamp 302 releases the zongzi leaves and continues to translate for a distance and close inward for a distance, until the end of the zongzi leaves completely exceeds the zongzi-shaped mold 402; close to The forming push plate 404 of the short side of the zong leaf first moves in a direction perpendicular to the movement direction of the supporting mechanism 2 until it exceeds the symmetry plane of the zong-shaped mold 402, and then moves along the side of the zong-shaped mold 402 to realize the rotational folding forming of the short side of the zong leaf, and the short side of the zong leaf is pressed against the zong-shaped mold 402 by the right corner support 202; after that, the forming push plate 404 on the other side performs the same movement to realize the rotational folding forming of the long side of the zong leaf, and the long side of the zong leaf is pressed against the zong-shaped mold 402 by the left corner support 202. Because the bottom edge of the zong leaf exceeds the bottom of the zong-shaped mold 402, when the zong leaf is rotationally folded and formed, the bottom of the four-cornered zong is doubly folded to avoid bottom leakage; finally, the bottom of the formed zong leaf is pressed against the zong-shaped mold 402 by the bottom support 204. After the formation of the rice dumpling leaves is completed, the single-component hopper 501 on the filling mechanism 5 fills the quantitative glutinous rice into the rice dumpling-shaped mold 402, and the unloading switch 403 moves upward to open the rice dumpling-shaped mold 402. At the same time, the rice dumpling-shaped mold 402 slowly moves upward to cooperate with the blower to fill the glutinous rice into the square rice dumpling for the first time.

[0042] After the first filling of the four-cornered rice dumpling is completed, the supporting mechanism 2 transports the four-cornered rice dumpling to the bottom of the double-component hopper 502 for filling with stuffing and a second filling of glutinous rice.

[0043] After the filling is completed, the four-corner rice dumpling is transported to the capping mechanism 6 by the supporting mechanism 2, and the two capping rotating plates 601 move simultaneously in a direction perpendicular to the movement direction of the supporting mechanism 2. When they touch the side of the four-corner rice dumpling, they rotate with the side of the four-corner rice dumpling as the axis to complete the folding of the rice dumpling leaves; then, the capping roller 602 moves along the movement direction of the supporting mechanism until it touches the side of the four-corner rice dumpling, and uses the capping rotating plate 601 as support to perform a preliminary folding of the rice dumpling leaves. Then, the supporting mechanism 2 continues to move, and cooperates with the capping roller 602 to complete the subsequent folding and capping of the rice dumpling leaves, and at the same time, the four-corner rice dumpling that has completed the capping is withdrawn from the capping mechanism 6.

[0044] After the capping is completed, the four-corner rice dumpling is transported to the bundling mechanism 7 by the supporting mechanism 2, and the right corner support 202 and the left corner support 203 are evacuated. At the same time, the winding mechanism 701 moves until the clamping plate 7012 contacts the four-corner rice dumpling, and the winding hand 7011 starts to rotate to wind the wire around the rice dumpling body. When winding, the winding mechanism 701 continues to move forward, and the distance between the two clamping plates 7012 increases to complete the first winding of the four-corner rice dumpling; then the winding mechanism 701 withdraws a distance, and at the same time, the right corner support 202 and the left corner support 203 move to fix the four-corner rice dumpling, and the spline cap 7051 on the rotating mechanism 705 moves to align with the supporting mechanism 2 The rotating spline shaft 207 is connected to the supporting plate 205, and driven by the rotating shaft 7052 and the gear set 7053, the supporting plate 205 is rotated to a certain angle; the support rod 7032 on the top angle forming mechanism 703 moves in the vertical direction until it contacts the rice dumpling leaves at the top of the four-cornered rice dumpling, and at the same time, the limiting rod 7034 moves to the side of the four-cornered rice dumpling top angle away from the winding mechanism 701, and the rice dumpling leaf clamping plate 7031 moves vertically downward to cooperate with the support rod 7032 to complete the folding of the rice dumpling leaves at the top of the four-cornered rice dumpling, and then the support rod 7032 is withdrawn, and the rice dumpling leaf clamping plate 7031 clamps the rice dumpling leaves, and the rice dumpling leaf cutter 7033 cuts off the excess rice dumpling leaves; then the rice dumpling The leaf clamp 7031 loosens the rice dumpling leaf, and the rotating mechanism 705 continues to rotate the carrying plate 205 by a certain angle until the side of the four-corner rice dumpling is perpendicular to the movement direction of the supporting mechanism 2, the positive angle support 201 and the left angle support 203 are evacuated, and the thread hooking needle 702 moves to a certain position near the top of the four-corner rice dumpling near the rewinding mechanism 704, and the thread hooking needle 702 is located above the first winding, and the needle head is parallel to the top of the rice dumpling. The winding mechanism 701 repeats the winding action from the farthest end, and after completing the second winding; the wire pressing plate 7403 on the rewinding mechanism 704 loosens the old thread head, and the winding column 7402 moves along a direction perpendicular to the movement direction of the supporting mechanism 2 Move to the winding range of the winding hand 7011, the winding hand 7011 winds the end of the wire around the winding post 7402, and then the winding post 7402 pulls the wire to the wire renewing mechanism 704, the wire pressing plate 7403 presses the wire tightly, and at the same time the spring pressure plate on the wire cutter 7401 presses the wire tightly, and the cutter cuts it to form a new thread end; finally, the wire hooking needle 702 rotates a certain angle in the direction where the needle head is away from the rice dumpling body, and at the same time withdraws a distance to hook the last wire wound on the four-cornered rice dumpling, then rotates a certain angle toward the rice dumpling body and withdraws to hook out the wire cut by the wire cutter 7401, completing the wire pressing and knotting of the four-cornered rice dumpling.

[0045] The bundled square rice dumplings are transported by the supporting mechanism to the next workstation for output.

[0046] The present invention has high action continuity, high reliability and high efficiency during the process of forming the rice dumpling leaves and bundling the four-corner rice dumplings.

[0047] In the present invention, starting from the transportation of the rice dumpling leaves, the manual workload is greatly reduced, and multiple stations are carried out simultaneously, which can meet the high-speed production requirements.

[0048] The above is only a preferred embodiment of the present invention and does not limit the present invention. It should be noted that a person skilled in the art can develop a variety of modifications and variations of similar mechanisms without departing from the principle and scope of the present invention, which should also be regarded as the protection scope of the present invention.
