Description

Technical Field

[0001] This utility model belongs to the field of zongzi (sticky rice dumpling) binding, specifically relating to a mechanical binding tool for automated zongzi packaging. Background Technology

[0002] The utility model patent with publication number CN206926865U and subject name "Automatic Zongzi Tying Machine" has IPC classification number B65B13 / 22. Its technical solution discloses that "the winding device includes a wire clamping mechanism, a wire laying mechanism, and a tensioning mechanism. The wire clamping mechanism is fixed to the right side of the large synchronous belt pulley by screws and is used to clamp one end of the cotton thread. It is used to clamp the thread end before the tying process begins, so that the two strands of thread are combined into one thread and enter the hook groove of the wire laying rod, and the thread end is released. Before knotting, the thread between the zongzi and the wire laying rod is clamped to prepare for the next tying action. The wire laying cam of the wire laying mechanism is installed on the distribution shaft through a threaded connection. The wire laying rod is ensured to be in close contact with the wire laying cam by a closed spring. The other end is connected to and cooperates with the rolling bearing and bearing seat."

[0003] Therefore, the above utility model patents have disclosed one of the technical solutions for an automatic zongzi-tying machine. However, while the technical solutions disclosed in these utility model patents focus on simulating manual tying, they also include multiple functions such as guiding, transmission, and control mechanisms. They do not further address the issue that the rotating shaft will not detach from the base when the winding rod is rotated to adjust its angle to adapt to different zongzi-tying needs, and therefore require further improvement.

Detailed Implementation

[0018] This utility model discloses a mechanical tying tool for automated packaging of zongzi (sticky rice dumplings). The following description, in conjunction with a preferred embodiment (Embodiment 1), is shown in the accompanying drawings. Figures 1 to 6 The specific embodiments of this utility model will be further described below.

[0019] See attached diagram. Figures 1 to 6 , Figures 1 to 4 The images show mechanical binding tools used for automated packaging of zongzi (sticky rice dumplings) from different perspectives. Figure 5 The auxiliary wire-tying module is shown. Figure 6 The base module is shown.

[0020] Example 1.

[0021] Preferably, the mechanical tying tool for automated packaging of zongzi includes an auxiliary tying module 100 and a base module 200, wherein: The auxiliary tying module 100 includes a winding rod 110 (the rope for tying zongzi can be pre-wound to the winding rod 110), a rotating shaft 120, and a positioning seat 130. The positioning seat 130 has a positioning seat main body 131 and two positioning seat extensions 132, which are integrally formed with the positioning seat main body 131. The rotating shaft 120 has a rotating shaft circumferential surface 121 and two oppositely distributed rotating shaft end faces 122. The winding rod 110 is fixedly connected to the rotating shaft circumferential surface 121, and the two positioning seat extensions 132 are rotatably connected to the two rotating shaft end faces 122. The base module 200 includes a base 210 and a limiting mechanism 220. The base 210 has a base groove 211. The positioning seat main body 131 is connected to the limiting mechanism 220, and the rotating shaft circumferential surface 121 is connected to the base groove 211. So that by rotating the winding rod 110, the rotating shaft 120 can rotate synchronously with the positioning seat 130, and during the rotation of the rotating shaft 120, the positioning seat 130 is limited by the limiting mechanism 220, so that the rotating shaft 120 always maintains close contact with the base 210 (specifically the base groove 211 of the base 210), and the rotating shaft 120 never leaves the base 210 (specifically the base groove 211 of the base 210); ultimately, the winding rod 110 can be manually changed in spatial position to match the needs of tying zongzi at different angles; at the same time, after the winding rod 110 rotates to a new spatial position, it has the ability to stably maintain the spatial position. When the rope for tying zongzi is pulled slightly during the zongzi tying process, the winding rod 110 can still maintain its spatial position.

[0022] The winding rod 110 is provided with a winding rod protrusion 111 and a winding rod section 112. One end of the winding rod section 112 is integrally formed with the winding rod protrusion 111, and the other end of the winding rod section 112 is fixedly connected to the circumferential surface 121 of the rotating shaft. The rope for tying zongzi is conveniently wound around the winding rod 110.

[0023] The positioning seat body 131 has a positioning seat positioning hole 133, and the limiting mechanism 220 includes a limiting post 221. One end of the limiting post 221 is connected to the positioning seat positioning hole 133, and the other end of the limiting post 221 is connected to the base 210 and fixedly connected to the base 210, so that the positioning seat 130 is limited by the limiting mechanism 220.

[0024] The limiting mechanism 220 also includes a spring 222, a bolt 223, and two limiting plates 224. The spring 222 is wound around the limiting post 221, and the two limiting plates 224 are respectively attached to the upper and lower surfaces of the positioning seat body 131. The bolt 223 is connected to one of the limiting plates 224. One end of the spring 222 abuts against the base 210, and the other end of the spring 222 abuts against the other limiting plate 224. This further enables the positioning seat 130 to be limited by the limiting mechanism 220.

[0025] The lower surface of the positioning seat body 131 has a positioning seat groove 134, which facilitates gripping the positioning seat 130.

[0026] It is worth mentioning that the spring coefficient and other technical features involved in this utility model patent application should be regarded as prior art. The specific structure, working principle and possible control methods and spatial arrangement of these technical features can be conventionally selected in the field and should not be regarded as the inventive point of this utility model patent. This utility model patent will not elaborate further.

[0027] For those skilled in the art, modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
