Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of zongzi winding, specifically relates to a zongzi winding machine. BACKGROUND

[0002] Zongzi is a food steamed by wrapping glutinous rice with zongzi leaves, and is one of the traditional Chinese festival foods of the Han nationality. As one of the traditional foods with the deepest historical and cultural accumulation in China, zongzi is spread far and wide. The custom of eating zongzi on the Dragon Boat Festival has been popular in China for thousands of years and has spread to Korea, Japan and Southeast Asian countries.

[0003] In the process of making zongzi, the wrapped semi-finished product needs to be bundled with a thread. At present, the zongzi is mostly bundled by manual winding, which is low in efficiency and the tightness cannot be guaranteed. A few use automatic winding machines for bundling.

[0004] For example, in the utility model patent application with the re-publication number "CN101142985B", an automatic zongzi tying machine is disclosed, which comprises a machine frame, a power transmission device, a wire arranging device, a winding device and a knotting device. The machine frame is provided with a zongzi clamping device mainly composed of a clamping head group for clamping zongzi. The winding device and the knotting device are arranged on the side of the zongzi clamping device. The clamping head group at least includes a front clamping head and a rear clamping head. The front clamping head is fixedly connected to a rotating frame, and the rotating frame is connected to a motor through the power transmission device. The rotating frame is connected to a front driven pulley of the power transmission device through a bolt. The middle part of the front driven pulley is connected to the machine frame through a bearing. The rotating frame has a hole, and the front clamping head is inserted into the hole and fixed by a screw. The rear clamping head is connected to a rear driven pulley of the power transmission device through a spline shaft. It has the characteristics of compact structure, high working efficiency, low cost, simple operation, and efficiency much higher than manual tying. It can realize automatic winding of zongzi, but it can only realize single-direction winding for several turns, and cannot realize complex winding of 7 turns horizontally and 2 turns vertically, which may lead to unstable and unreliable bundling.

[0032] A zongzi winding method, comprising the following steps:

[0033] Step S1: the rope for wrapping zongzi on the first thread reel 420 is first wound through the first thread clamping device 470, then passes through the first thread winding pipe 430, and finally is clamped by the knotting device 110, the zongzi mold is first rotated so that the first mold 310 and the second mold 320 are arranged at the left side of the third mold 330 and the fourth mold 340;

[0034] Step S2: after the zongzi is wrapped with zongzi leaves, the zongzi is placed on the zongzi mold, the second motor 410 drives the first rotating disc 400 to rotate, the first thread winding pipe 430 rotates and drives the rope to wind the zongzi on the zongzi mold, at the same time, the first motor 440 drives the first screw rod 450 to rotate, the first screw rod 450 cooperates with the first threaded block 461 to drive the first transverse moving frame 460 to move, and the rope is wound on the zongzi for 7 turns;

[0035] Step S3: the first driving motor 281 and the second driving motor 282 are started to drive the second gear 283 and the fourth gear 284 to rotate, then drive the first rotating shaft 260 and the second rotating shaft 270 to rotate, and drive the zongzi mold to rotate by 90 degrees through the limiting of the first outer threaded bearing 291 and the second outer threaded bearing, the second motor 410 drives the first rotating disc 400 to rotate, the first thread winding pipe 430 rotates and drives the rope to continue to wind the zongzi for 2 turns;

[0036] Step S4: the knotting device 110 automatically knots and cuts the rope, and the packaged zongzi is taken out.

[0037] In the prior art, the zongzi packaging is only wound in one direction (generally 6-8 turns), but single-direction winding is prone to loose bundling, that is, the rope will fall off, but the present application can realize complex winding of 7 turns horizontally and 2 turns vertically. Since the shape of zongzi is similar to a triangular pyramid, only four edges can be wound in single-direction winding, and the remaining two edges are not bound by the rope. The complex winding of 7 turns horizontally and 2 turns vertically of the present application can also wind the remaining two edges, thereby realizing mutual constraint of winding and ensuring the reliability of winding.

[0038] It is worth mentioning that the knotting device 110 commonly used in the market can be used, for example, the knotting device 110 disclosed in CN109007598A, that is, the knotting device 110 of the present application can use the prior art, so the structure is not described.

[0040] It is worth mentioning that the knotting device 110 and other technical features involved in the present utility model patent application should be regarded as prior art. The specific structure, working principle and possible control method and spatial arrangement method of these technical features can be selected conventionally in the art, and should not be regarded as the utility model point of the present utility model patent. The present utility model patent will not be further expanded and described in detail.

[0041] For those skilled in the art, the technical solutions described in the foregoing embodiments can be modified or some technical features can be replaced by equivalents. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
