Description

Technical Field

[0001] This utility model relates to the field of material packaging technology, specifically to an automatic packaging machine for small-bag sauerkraut. Background Technology

[0002] The bag-type automatic packaging machine replaces manual packaging, realizing packaging automation for large and small enterprises. Operators only need to stack hundreds of bags at a time on the bag picking section of the machine. The machine's mechanical claw will automatically pick up the bags, print the date, open the bags, signal the metering device to measure and dispense the material, seal the bags, and output the product.

[0003] In some food processing fields, such as the seasoning packets inside instant noodles, the small size makes it inconvenient to clamp the packaging bag during packaging. Furthermore, existing automatic bag-feeding packaging machines are only suitable for one or two sizes of packaging bags and cannot package other sizes of packaging bags, resulting in poor applicability.

It should be understood that the specific embodiments described herein are only for illustration and explanation of this utility model and are not intended to limit this utility model in any way. The accompanying drawings in this utility model are only for illustrative purposes and to facilitate understanding of the embodiments and are not intended to limit this utility model in any way.

[0082] It should be noted that the structures, proportions, sizes, etc. shown in the accompanying drawings are only for the purpose of assisting those skilled in the art in understanding and reading the content disclosed in the specification, and are not intended to limit the conditions under which the present invention can be implemented. Any modifications to the structure, changes in the proportions, or adjustments to the size, without affecting the effects and purposes that the present invention can produce, should still fall within the scope of the technical content disclosed in the present invention.

[0083] As described in the background section, existing automatic packaging machines are not convenient for clamping smaller packaging bags during use, and the clamping position cannot be adjusted arbitrarily according to the size of the packaging bag. Therefore, they cannot automatically place and clamp packaging bags with large size differences.

[0084] Based on the above reasons, in order to solve the above problems, this utility model provides the following technical solution:

[0085] Example 1,

[0086] Please see the appendix Figure 1 and attached Figure 2 An automatic packaging machine for small-bag pickled cabbage includes a clamping and conveying mechanism 1300, which is horizontally arranged and clamps the packaging bag and maintains intermittent conveying.

[0087] The bag-releasing mechanism 200 is located on the outside of the feed end of the clamping and conveying mechanism 1300;

[0088] The bag-picking mechanism 300 uses the bag-suction mechanism 1100 to sequentially pick up the packaging bags from the bag-dispensing mechanism 200 and transfer them to the clamping and conveying mechanism 1300.

[0092] The sealing mechanism 800 is located on the outside of the discharge end of the clamping and conveying mechanism 1300 and seals the packaged bag.

[0093] Below the sealing mechanism 800, there is also a material discharge platform 900;

[0094] Both the bag-laying mechanism 200 and the clamping and conveying mechanism 1300 can be adjusted according to the size of the packaging bag.

[0095] Example 2,

[0096] Please see the appendix Figure 3 Based on Example 1, in order to solve the problem that the various mechanisms cannot achieve linkage, a feasible solution is provided here.

[0097] The automatic packaging machine also includes a box body 100. The clamping and conveying mechanism 1300, bag picking mechanism 300, bag opening mechanism 400, material feeding mechanism, bag closing mechanism 600 and sealing mechanism 700 are all arranged on the side of the box body 100 and driven by the transmission mechanism 1200 inside the box body 100.

[0098] In this embodiment, the transmission mechanism includes a drive motor, a belt drive mechanism, a gear drive mechanism, a linkage mechanism, etc. The specific connection method and linkage with each mechanism are conventional methods in the mechanical field, and will not be described in detail here.

[0099] Example 3,

[0100] Please see the appendix Figure 4 Based on Example 2, to address the issue of limited practicality due to the inability to accommodate packaging bags of different sizes, a feasible solution is provided here.

[0101] The bag-dispensing mechanism 200 specifically includes,

[0102] The support frame 202 is kept horizontally supported by the first support column 201;

[0103] The first adjusting plate 203 is arranged opposite to each other on the top of the support frame 202 and a limit post 204 is provided on the first adjusting plate 203;

[0104] The second adjusting plate 206 is arranged adjacent to the first adjusting plate 203 and a limit plate 207 is provided on the second adjusting plate 206;

[0105] The support roller 205 is disposed on the inner end of the support frame 202;

[0106] The first adjusting plate 203 and the second adjusting plate 206 are both movably mounted on the support frame 202 through strip holes.

[0107] Example 4,

[0108] Please see the appendix Figure 2 and attached Figure 5 Based on Embodiment 2, to address the problem of being unable to individually pick up and place packaging bags from the bag-dispensing mechanism onto the clamping and conveying mechanism, a feasible solution is provided here.

[0109] The bag suction mechanism 1100 is located below the support frame 202 and passes through the gap between the support frame 202 and the support roller 205 in a lifting manner to suck the packaging bag downwards. The bag picking mechanism 300 specifically includes...

[0110] The second support column 301 has a rotating rod 303 rotatably mounted on its top.

[0111] The first drive arm 302 has one end inserted into the housing 100 and connected to the transmission mechanism 1200, and the other end connected to the rotating rod 303;

[0112] The third support column 304 is fixed at one end to the rotating rod 303;

[0113] Two clamping plates 307 are positioned opposite each other below the other end of the third support column 304;

[0114] The transmission gear 306 is rotatably mounted on the other end of the third support column 304 and connected to the clamping plate 307;

[0115] The second drive arm 305 is rotatably mounted on the third support column 304 and drives the transmission gear 306 to rotate.

[0116] In this embodiment, the bag suction mechanism specifically includes a lifting device and a vacuum suction cup. The lifting device drives the vacuum suction cup to rise and fall, which can suck out the packaging bag placed at the bottom from the gap between the support frame and the support roller, making it easy for the bag-removing mechanism to take it away.

[0117] Example 5,

[0118] Please see the appendix Figure 6 Based on Example 2, in order to solve the problem of not being able to open the opening of a clamped and fixed packaging bag, a feasible solution is provided here.

[0119] The bag opening mechanism 400 specifically includes,

[0120] Two third drive arms 401 are rotatably mounted above the clamping and conveying mechanism 1300 and driven by the transmission mechanism 1200;

[0121] Two support plates 405 are arranged opposite each other and fixed above the clamping and conveying mechanism 1300;

[0122] Multiple sliders 404 are slidably disposed on the support plate 405 and their sliding direction is kept in accordance with the conveying direction of the clamping and conveying mechanism 1300;

[0123] Two driven rods 403 are respectively fitted inside two sliders 404 and are connected to the third drive arm 401 through the connecting plate 402 at both ends;

[0124] Multiple movable clamping blocks 406 are respectively set on the opposite ends of the sliders 404 on the two support plates 405 for clamping the packaging bag;

[0125] Two vacuum suction cups 407 are positioned opposite each other between the gaps of the clamping blocks 406 and are driven by the first linear drive device 408;

[0126] The air blowing pipe 409 is vertically downward between the two vacuum suction cups 407.

[0127] The specific operation of opening the bag is as follows: First, the two vacuum suction cups 407 are driven by the first linear telescopic device 408 to keep close and contact the bag opening. After vacuuming, the first linear telescopic device 408 moves in the opposite direction to pull open the two vacuum suction cups 407 and the bag opening. During this process, the air blowing pipe 409 discharges positive pressure air into the bag opening to facilitate the opening of the bag opening. At the same time, the third drive arm 401 rotates under the drive of the transmission mechanism 1200, pushing the driven rod 403 and the slider 404 on the same support plate 405 to move in the direction of closer proximity. Then, the movable clamping block 406 squeezes the clamped bag inward to facilitate the opening of the bag opening.

[0128] Furthermore, the bag closing mechanism 700 is similar in structure to the bag opening mechanism 400, except that the bag closing mechanism 700 does not contain a vacuum suction cup or an air blowing pipe, and the bag closing mechanism 700 and the bag opening mechanism 400 move in opposite directions during the automated packaging process.

[0129] Example 6,

[0130] Please see 2 and Appendix Figure 7 Based on Example 2, in order to solve the problem of not being able to guarantee quantitative filling during the filling process, a feasible solution is provided here.

[0131] The feeding mechanism includes a main feeding mechanism 500 and an auxiliary feeding mechanism 600. A weighing mechanism 1000 is disposed below the feeding mechanism. The weighing mechanism 1000 includes...

[0132] The drive motor 1001 is located on the outside of the housing 100 and fixed below the clamping and conveying mechanism 1300;

[0133] The rotating disk 1002 is fixed on the output shaft of the drive motor 1001;

[0134] The lifting plate 1004 is slidably positioned above the drive motor 1001 in the vertical direction;

[0135] The transmission rod 1003 is rotatably connected at one end to the outside of the lifting plate 1004, and rotatably connected at the other end to the rotating disk 1002 and is kept eccentrically set.

[0136] Weighing pan 1005 is fixed to the top of lifting plate 1004 and corresponds to main feeding mechanism 500 and auxiliary feeding mechanism 600 respectively.

[0137] Furthermore, the main feeding mechanism 500 and the auxiliary feeding mechanism 600 can hold the same material so that if the material is found to be too light after weighing, it can be replenished in time through the auxiliary feeding mechanism 600. Alternatively, different materials can be placed for separate filling.

[0138] Furthermore, the feeding mechanism can be a conventional filling mechanism, such as a spiral feeding filling mechanism, to ensure more uniform feeding.

[0139] The weighing pan can be a conventional weighing scale. During the weighing process, the weighing pan is raised by the rotation of the drive motor 1001 and comes into contact with the packaging bag below the main feeding mechanism 500 and the auxiliary feeding mechanism 600 to achieve weighing. If the material being weighed is found to be too light, it can be replenished by the auxiliary feeding mechanism 600. If it is found to be too heavy, an alarm signal will be issued.

[0140] Example 7,

[0141] Please see the appendix Figure 8 ~Appendix Figure 10 Based on Example 1, to address the problem that the packaging bag cannot move smoothly to various mechanisms for packaging processes after being clamped, a feasible solution is provided here.

[0142] The clamping and conveying mechanism 1300 includes an upper component and a lower component. The upper component clamps or releases the packaging bag, and the lower component clamps or releases the packaging bag and conveys it along the conveying direction. Please refer to the appendix for details. Figure 9 The upper-layer components specifically include,

[0143] Support arm 1301 is fixed to the side of housing 100;

[0144] The slide bar 1302 is located below the support arm 1301;

[0145] Two first clamping plates 1303 are arranged oppositely below the slide rod 1302 and connected to the slide rod 1302 through a slide block 1304. The slide block 1304 drives the first clamping plates 1303 to slide linearly along the direction of the slide rod 1302.

[0146] The fourth drive arm 1305 is connected at one end to the transmission mechanism 1200 of the housing 100, and at the other end to the first clamping plate 1303 to drive the two first clamping plates 1303 to move in opposite directions.

[0147] Multiple fixed clamping blocks 1306 are respectively set on the opposite ends of the two first clamping plates 1303 and are kept in a movable connection.

[0148] In this embodiment, please refer carefully to the appendix. Figure 10 The lower-level components specifically include,

[0149] Two second clamping plates 1307 are arranged opposite each other below the first clamping plate 1303;

[0150] Two sliding plates 1308 are slidably mounted on two second clamping plates 1307 and are driven to move along the length direction of the second clamping plates 1307 by the second linear telescopic device 1309 at the end of the second clamping plate 1307.

[0151] The rotating arm 1310 is hinged to the rotating shaft 1311 in the middle. One end of the arm is connected to the second clamping plate 1307, and the other end is rotatably connected to the fourth drive arm 1312. The fifth drive arm 1312 is driven to move linearly through the transmission mechanism 1200, which pushes or pulls the rotating arm 1310 to rotate around the rotating shaft 1311, causing the two second clamping plates 1307 to move in opposite directions.

[0152] Multiple fixing blocks 1306 are respectively set on the opposite ends of the two sliding plates 1308 and are kept in a movable connection.

[0153] During the clamping and conveying of the packaging bag, the upper component can clamp the packaging bag. When conveying is required, the lower component moves to clamp the packaging bag, while the upper component releases the packaging bag. Then, the lower component conveys the clamped packaging bag to the next process position. After completion, the upper component moves to clamp the packaging bag, while the lower component releases the packaging bag and returns to its original position, so that the packaging bag can be conveyed again in the future.

[0154] Example 8,

[0155] Based on Example 7, to address the problem of limited practicality caused by the inability to clamp packaging bags of different sizes, a feasible solution is provided here.

[0156] The first clamping plate 1303 and the sliding plate 1308 have a dovetail-shaped cross-section. The fixing block 1306 is slidably disposed on the first clamping plate 1303 or the sliding plate 1308 and fixed by bolts and nuts.
