Description

Technical Field

[0001] The present invention belongs to the technical field of automatic zongzi wrapping machines, and particularly relates to a component for wrapping and sealing zongzi leaves. Background Art

[0002] Compared with manual zongzi wrapping, the difference of an automatic zongzi wrapping machine is that the former has a high degree of automation and relies on a preset program to complete most or even all of the zongzi wrapping steps, while the latter is all completed manually by operators, relying on the experience of the operators. However, the zongzi wrapping steps of both are the same and can generally be divided into the following four steps: 1. Bend the zongzi leaves into a conical shape; 2. Put the materials down; 3. Wrap and seal the zongzi leaves; 4. Tie the zongzi.

[0003] On the other hand, the component for wrapping and sealing zongzi leaves of an automatic zongzi wrapping machine should at least include the following two functions when wrapping common triangular zongzi:

[0004] First, bend the crossed ends of the zongzi leaves by about 90° to a horizontal state to cover the materials.

[0005] Second, continue to bend the ends of the zongzi leaves by about 90°, and at this time the ends face down to form the part for tying the zongzi.

[0006] The Chinese utility model patent with the patent announcement number CN201612135U and the announcement date of October 27, 2010 discloses an automatic zongzi wrapper, including: an outer shell body, the outer shell body has a cubic structure; an inner shell body, the inner shell body is arranged in the outer shell body; a lid, the lid covers the outer shell body; a plurality of zongzi leaves, the plurality of zongzi leaves are attached to the inner side wall of the inner shell body; and a packaging rope, the packaging rope is tied to the outer shell body and the lid.

[0007] The general usage method of the wrapper in this utility model patent is as follows:

[0008] Step 1: Attach a wide zongzi leaf to the inner side wall of the inner shell body.

[0009] Step 2: Put the inner shell body into the outer shell body and pour auxiliary materials such as rice into the zongzi leaf.

[0010] Step 3: Fold the edge of the zongzi leaf inward and then cover the lid.

[0011] Step 4: Fix the zongzi with a fixing rope through the grooves, the "-" shaped groove and the "+" shaped groove.

[0012] However, during the actual production and use process of this wrapper, there are at least the following deficiencies, that is, the technical problems to be solved by the present invention:

[0013] The lid closing operation still needs to be done manually by the operator, so the efficiency is relatively low, and the wrapper is not suitable for common triangular rice dumplings.

[0014] Therefore, in summary, there is an urgent need for a new type of wrapping and sealing component with a high degree of automation and sufficient sealing of the rice dumplings leaves, which can be used to seal and close the common triangular rice dumplings. Summary of the invention

Specific implementation mode

[0041] The following is only a preferred embodiment of the present invention and does not limit the scope of the present invention.

[0042] As shown in the attached Figures 1-11 As shown, a component for sealing the zongzi leaf wrapping includes two bending plate units 1 respectively used for bending two zongzi leaf ends a twice, a lifting and rotating plate unit 2 arranged on the bending plate unit 1, and a lower arc rotating plate unit 3 for attaching two zongzi leaf ends a to the zongzi body b.

[0043] In this embodiment, the component further includes a material tablet 6. The material tablet 6 is used up and withdrawn before the zongzi leaf end a is bent. It is paired with a common mechanical arm that can move up, down, left, right, forward, and backward to ensure that the zongzi material has a sufficient and appropriate density.

[0044] In addition, the general usage method of this component is as follows:

[0045] 1. The zongzi is placed on a moving mold and comes to the position directly below and in front of the bending plate unit 1;

[0046] 2. The lifting and rotating plate unit 2 is activated, that is, it first moves downward and then rotates approximately 90°, allowing the bending plate unit 1 to bend two zongzi leaf ends a twice, that is, the zongzi leaf end a first covers the material and then rotates downward. At this time, the zongzi leaf wrapping and sealing operation is basically completed. After the above downward rotation section is tied, the zongzi is basically made;

[0047] 3. Then, the lower arc-shaped rotating plate unit 3 is rotated and used to better arrange the longer part of the rice dumpling leaf end a so that the longer part can be better attached to the rice dumpling body b, so that the whole rice dumpling is more beautiful and less likely to fall apart.

[0048] The longer portion may be slightly bent downward or laterally, for example Figure 8 , or may bend sharply downward or laterally, such as Figure 9 After that, use the rope to tie 2-4 circles between the initial tying part d and the ending tying part e, and the whole zongzi is complete.

[0049] It also includes a rice dumpling leaf tightening cylinder unit 4 which is arranged on the lifting and rotating plate unit 2, connected to the bending plate unit 1, and used for transversely folding the two bending plate units 1.

[0050] In this embodiment, the two ends a of the rice dumplings are bent twice, forming a "horizontal section" and a "vertical section", the former being used for capping materials and the latter being used for being tied with ropes. Figure 7 As shown, the two protruding corners on the left and right may be prone to rice leakage, so the use of the cylinder unit 4 for tightening the rice leaves allows the two bending plate units 1 to have a lateral folding function, which can further narrow the gaps at the protruding corners and reduce the probability and degree of rice leakage. This is how to imitate and highly restore the skills of hand-made rice dumplings.

[0051] The bending plate unit 1 includes a protruding plate 101 for bending the end a of the rice leaf twice, and an initial vertical plate 102 arranged on the protruding plate 101 and used for pressing down and fixing the first bending section of the rice leaf end a.

[0052] In an embodiment, the protruding plate 101 is used to bend in sequence to form the above-mentioned "horizontal section, vertical section", and the initial vertical plate 102 becomes horizontal after use, and is used to press and fix the above-mentioned "horizontal section", and the sealing operation is basically completed.

[0053] The initial vertical plate 102 is arranged on the cylinder unit 4 for tightening the rice dumpling leaves, and the protruding plate 101 and the initial vertical plate 102 are both arc-shaped.

[0054] In this embodiment, the former is an arc-shaped curved plate and the latter is an arc-shaped flat plate. The arc-shaped style can ensure that large or small rice leaves can be pressed and bent, that is, to increase the effective bending area.

[0055] The two protruding plates 101 are offset up and down, the two initial vertical plates 102 are offset front and back, and the bent plate unit 1 further includes a middle extension section 103 arranged on the higher protruding plate 101 .

[0056] In this embodiment, due to the existence of the cylinder unit 4 for tightening the zongzi leaves, and since two zongzi leaf ends a need to be appropriately tightened to narrow the gap at the protruding angle, the two bending plate units 1 not only need to be able to close, but also to be able to close significantly.

[0057] Therefore, it is set that the two bending plate units 1 are completely misaligned, that is, there is a small misalignment both vertically and horizontally, and the middle extension section 103 is also introduced, so that the two protruding plates 101 can not only be misaligned and overlapped, but also be significantly overlapped, in order to relatively tighten the two zongzi leaf ends a significantly and avoid a large amount of rice leakage at the upper sealing part of the zongzi.

[0058] The lifting and rotating plate unit 2 includes a connecting plate 201 for installing two cylinder units 4 for tightening the zongzi leaves, a side radial plate 202 provided on the connecting plate 201, a vertical rotating cylinder 203 provided on the side radial plate 202, and a vertical telescopic cylinder 204 provided on the vertical rotating cylinder 203.

[0059] In this embodiment, the vertical telescopic cylinder 204 first moves downward, and then the vertical rotating cylinder 203 rotates forward, that is, rotates towards the zongzi direction, so that the bending plate unit 1 covers the zongzi body b. In other words, initially the bending plate unit 1 is located obliquely above and behind the zongzi body b.

[0060] The forward and downward rotation distances of the bending plate unit 1 depend on the length of the side radial plate 202, and the size of the side radial plate 202 is the radius of the rotation curve of the bending plate unit 1.

[0061] The lower arc rotating plate unit 3 includes a horizontal rotating cylinder 301, and a lower arc plate 302 provided on the horizontal rotating cylinder 301 and used for attaching two zongzi leaf ends a to the zongzi body b.

[0062] In this embodiment, the height of the horizontal rotating cylinder 301 is generally the same as that of the zongzi body b, and the lower arc plate 302 is appropriately bent to ensure that the longer segments of the zongzi leaf ends a can be all attached to the zongzi body b.

[0063] At this time, the longer segment may bypass the edge of the zongzi body b, or may just be bent slightly downward and attached. Both of these situations are normal, and the final zongzi bundling operation ensures that the above-mentioned longer segment can be appropriately bundled.

[0064] Among them, the so-called "arc" of the protruding plate 101, the initial vertical plate 102, and the lower arc plate 302 can be either a part of a circle or a part of an ellipse.

[0065] The cylinder unit 4 for tightening the zongzi leaves includes a horizontally telescopic cylinder 401 arranged on the connecting plate 201, and a horizontal connecting rod 402 which is arranged on the horizontally telescopic cylinder 401 and used for installing the initial vertical plate 102.

[0066] In this embodiment, the cylinder shafts of the two horizontally telescopic cylinders 401 are arranged face to face. One end of the horizontal connecting rod 402 is connected to the side surface of the initial vertical plate 102, and the other end is connected to the above-mentioned cylinder shaft.

[0067] It further includes a frame unit 5 for installing the vertically telescopic cylinder 204 and the horizontally rotating cylinder 301. The frame unit 5 includes a bottom plate 501, a high-position inverted L-shaped plate 502 which is arranged on the bottom plate 501 and used for installing the vertically telescopic cylinder 204, and a low-position inverted L-shaped plate 503 which is arranged on the bottom plate 501 and used for installing the horizontally rotating cylinder 301.

[0068] In this embodiment, the frame unit 5 is only one of the feasible ways for the assembly to be installed and used. For example, a vertical suspension column can be equipped for both the vertically telescopic cylinder 204 and the horizontally rotating cylinder 301.

[0069] Finally, the advantages of the assembly in this embodiment are summarized as follows.

[0070] First, the bending plate unit 1 plus the lifting and rotating plate unit 2 can initially wrap and seal the zongzi body b, ensuring the automation of the zongzi sealing operation.

[0071] Second, the lower arc rotating plate unit 3 can further gather the end a of the zongzi leaves, so that there is no large protruding end on the zongzi, greatly reducing the risk of the zongzi leaves being pulled and the zongzi falling apart.

[0072] Third, the cylinder unit 4 for tightening the zongzi leaves can also relatively gather the two bending plate units 1, so that the corner part of the sealing part of the zongzi body b can be properly closed, reducing the probability of rice leakage at this place.

[0073] Fourth, after the lower arc plate 302 presses the zongzi leaves, the bundling operation is carried out along its upper edge, ensuring the sealing shape and sealing method of the zongzi, which is convenient for the subsequent zongzi bundling operation.

[0074] Fifth, this assembly for wrapping and sealing zongzi leaves is suitable for making triangular zongzi, with high overall sealing operation efficiency and good stability.

[0075] Sixth, for all the cylinders in this assembly, only a common timing controller needs to be equipped to realize the full automation of the entire wrapping and sealing operation. Therefore, the installation and use costs of the assembly are relatively low, and a very precise control system is not required.

[0076] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments, and various modifications can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those of ordinary skill in the art. These are all non-creative modifications and are protected by the patent law as long as they are within the scope of the claims of the present invention.
