Description

Technical Field:

[0001] The utility model relates to the technical field of automatic production, and particularly refers to an automatic packaging device for packaging snail rice noodles. Background Art:

[0002] The automatic packaging device for snail rice noodles is a device specifically used for the production and processing of snail rice noodles, which mainly automatically loads semi-finished fan bags and other ingredient bags into the total packaging bag for overall packaging and sale. Most of the commonly used food production and packaging devices on the market adopt disk-type rotary position transfer. Although it can make the equipment layout more compact to a certain extent, for most enterprise factories, the ring-layout equipment will affect the placement of other equipment and actually occupy more space. For example, in a multi-station packaging machine for packing snail rice noodles with the Chinese patent application publication number CN116729721A, in the technical solution disclosed in this patent, a packaging bag conveying device (5), a staple food bagging device (6), a side dish packaging bag device (7), a sauce packaging bag device (8) and a sealing device (9) are sequentially arranged on the periphery of a rotatable machine table (2), and an output conveyor belt (3) is located below the sealing device (9). This layout design can make the structure more compact when using a single production device. However, for the production of snail rice noodles, this packaging machine is only a general assembly device, and other devices are still needed to separately package the staple food, side dishes, sauce packets, etc. Therefore, this ring-shaped divergent layout design centered on the rotatable machine table (2) will greatly occupy the surrounding space, making it impossible to arrange other equipment in the same production workshop. For food production, the environmental requirements for the workshop are often strict. If multiple workshops are used to place the production and packaging equipment for different processes, it will not only greatly increase various costs of the enterprise, but also there is a risk of contamination when transferring food raw materials between workshops, presenting relatively large potential safety hazards.

The transposition transfer mechanism 2 arranged in a runway shape is used for the circular transfer of materials, so that other working mechanisms do not require an overly long production line caused by side-by-side placement, nor an overly large occupied space caused by circumferential distribution placement, thereby reducing the overall occupied space, facilitating the placement of other process equipment, and being conducive to reducing the factory building cost.

[0035] In this embodiment, there is one material arranging and bag pulling machine 4 for automatically feeding the powder bags 40, and there are seven material arranging machines 5 for automatically feeding different material bags 50, including at least pickled bamboo shoots bags, fried bean curd with peanuts, acetic acid, snail sauce, chili oil, etc.

[0036] The position-changing transfer mechanism 1 includes a first frame 11, a support bottom beam frame 12 arranged on the first frame 11 and spliced into a runway shape, a track 13 installed on the support bottom beam frame 12 and spliced into a runway type, a plurality of slider seats 14 slidably installed on the track 13 and used to carry the jaw device 8, a chain 15 arranged inside the track 13 to connect the slider seats 14 in series, a first sprocket 16 and a second sprocket 17 arranged at both ends of the track 13 and meshed with the chain 15, and a first driving device 18 for driving the first sprocket 16 and the second sprocket 17 to rotate.

When the clamping claw device 8 is at the bag feeding mechanism 2, the clamping claw merging device A is inserted into the stop device 88 to push the total rotation pin 87, so that under the action of the reset tension spring, the left clamp seat 82 and the right clamp seat 83 are pulled to swing together, and the total rotation pin 87 is retreated to the rear end of the stop device 88. At this time, the left clamping claw 84 and the right clamping claw 85 squeeze the packaging bag 20 as the left clamp seat 82 and the right clamp seat 83 are brought together, so that the opening of the packaging bag 20 is propped open, thereby facilitating the subsequent workstations to put various materials into the packaging bag 20 in sequence.

[0040] The left clamping jaw 84 includes a first fixed clamping block 841 cantilevered on the left clamping seat 82, a first movable clamping block 842 hingedly mounted on one end of the first fixed clamping block 841 and cooperating to tighten the packaging bag 20, a sliding inner pin 843 movably arranged in the first fixed clamping block 841 and hingedly connected to the first movable clamping block 842, a compression spring sleeved on the sliding inner pin 843 and used to push the sliding inner pin 843 to pull the first movable clamping block 842 to swing and clamp, a tail pin 845 arranged at the other end of the first fixed clamping block 841 and used to stop the sliding inner pin 843, and a support guide sleeve 846 arranged at the tail of the sliding inner pin 843 and extending out of the first fixed clamping block 841. The structure of the right clamping jaw 85 is the same as that of the left clamping jaw 84. The ends of the left clamping seat 82 and the right clamping seat 83 are also provided with a left spring pin 821 and a right spring pin 831 for installing the two ends of the reset spring.

[0041] An open-clamping device 80 is further provided on the first frame 11, which is located beside the bag-feeding mechanism 2 and below the clamping jaw device 8. The open-clamping device 80 includes a second mounting support 801, an open-clamping cylinder 802 arranged on the second mounting support 801 and horizontally perpendicular to the track 13, an open-clamping connecting rod 803 mounted on the open-clamping cylinder 802 and used to push the left clamping jaw 84 and the right clamping jaw 85 to open, and a first loose-clamping block 804 and a second loose-clamping block 805 arranged at both ends of the open-clamping connecting rod 803 and respectively used to contact and push the sliding inner pin 843 to compress the return spring by contacting and pushing the support guide sleeve 846 in the left clamping jaw 84 and the right clamping jaw 85. Among them, a bag-feeding baffle 806 for positioning and stopping the packaging bag 20 is arranged at the end of the second mounting support 801, and a first strip hole and a second strip hole for adjusting the distance between the first loose-clamping block 804 and the second loose-clamping block 805 are arranged at both ends of the open-clamping connecting rod 803.

[0042] In the default state, the left clamping jaw 84 and the right clamping jaw 85 are in a closed state. When the clamping jaw device 8 moves to the bag-feeding mechanism 2, the open-clamping device 80 will push the support guide sleeve 846 of the left clamping jaw 84 and the right clamping jaw 85 to move forward. Under the push of the sliding inner pin 843, the first movable clamping block 842 swings open relative to the first fixed clamping block 841 and compresses the return spring. At this time, the bag-feeding mechanism 2 sends the packaging bag 20 between the first movable clamping block 842 and the first fixed clamping block 841 of the left clamping jaw 84 and the right clamping jaw 85. Then, the open-clamping device 80 retracts and disengages from the sliding inner pin 843. At this time, the return spring will push the sliding inner pin 843 to retreat and pull the first movable clamping block 842 to close relative to the first fixed clamping block 841, clamping the packaging bag 20.

[0043] The stop device 88 includes a left check seat 881 and a right check seat 882 which are installed on the first mounting support seat 81 and symmetrically located on both sides of the total rotating pin 87, a left stop block 883 and a right stop block 884 which are respectively hinged to the left check seat 881 and the right check seat 882 and can swing and press against one side of the total rotating pin 87, a left stop spring arranged in the left check seat 881 and used to eject the left stop block 883, and a right stop spring arranged in the right check seat 882 and used to eject the right stop block 884. The total rotating pin 87 will move between the left check seat 881 and the right check seat 882 under the pulling force of the reset tension spring. In the default state, the left stop spring and the right stop spring of the stop device 88 will eject the left stop block 883 and the right stop block 884 out of the left check seat 881 and the right check seat 882 and be in the moving stroke of the total rotating pin 87. When the jaw device 8 initially clamps the packaging bag 20, the left stop block 883 and the right stop block 884 of the stop device 88 will abut against the total rotating pin 87. At this time, the left jaw 84 and the right jaw 85 are in a relatively parallel state. When it is necessary to open the opening of the packaging bag 20, the jaw merging device inserts the jaw release lever B3 into the stop device 88 to push the left stop block 883 and the right stop block 884 back into the left check seat 881 and the right check seat 882. Subsequently, during the retraction process of the jaw release lever B3, the total rotating pin 87 is pushed backward by the left jaw seat 82 and the right jaw seat 83 under the action of the reset tension spring. Since the left stop block 883 and the right stop block 884 have been ejected, the total rotating pin 87 can smoothly cross over the stop device 88, so that the reset tension spring can continue to pull the left jaw seat 82 and the right jaw seat 83 closer to open the opening of the packaging bag 20. When it is further necessary to close the packaging bag 20, the jaw push rod A3 of the jaw merging device A pushes the total rotating pin 87 forward. At this time, since the jaw push rod A3 is located below the stop device 88, when the jaw merging device A ejects the total rotating pin 87 out of the stop device 88, the left stop spring and the right stop spring will eject the left stop block 883 and the right stop block 884 out of the left check seat 881 and the right check seat 882. Then, when the jaw push rod A3 retracts, the left stop block 883 and the right stop block 884 will press against the total rotating pin 87 to restrict its further backward movement, so that the left jaw 84 and the right jaw 85 are in a relatively parallel state to straighten and close the opening of the packaging bag 20.

[0044] The clamping jaw merging device includes a second support seat B1, a second cylinder B2 disposed on the second support seat B1, and a clamping arm release rod B3 installed on the piston of the second cylinder B2 and capable of being inserted into the stop device 88 to push out the master rotation pin 87. The clamping jaw merging device A includes a third support seat A1, a third cylinder A2 disposed on the third support seat A1, and a clamping arm push rod A3 installed on the piston of the third cylinder A2 and used to push the master rotation pin 87 out of the stop device 88. The clamping arm release rod B3 presses against the upper end of the master rotation pin 87 and can push the left check block 883 and the right check block 884 back into the left check seat 881 and the right check seat 882. The clamping arm push rod A3 presses against the lower end of the master rotation pin 87.

The bag opening mechanism 3 is located above the jaw closing device and cooperates with the jaw closing device to open the opening of the packaging bag 20. When the bag taking jaw arm 23 drives the packaging bag 20 to move below the bag opening mechanism 3, the third air cylinder 38 drives the left swing arm 32 and the right swing arm 33 to swing, so that the left suction cup 35 and the right suction cup 36 are attached to both sides of the packaging bag 20. After the left suction cup 35 and the right suction cup 36 adsorb the packaging bag 20, the third air cylinder 38 pushes the left swing arm 32 and the right swing arm 33 to swing open, pulling open the opening of the packaging bag 20, and blowing gas into the packaging bag 20 through the nozzle device 37 to expand the inside of the packaging bag 20, so as to facilitate the subsequent process of putting various materials into the packaging bag 20. With the cooperation of the jaw opening device A, the jaw device 8 is first closed to prevent the opening of the packaging bag 20 from being straightened and unable to be opened. Of course, during the closing process of the jaw device 8, the opening of the packaging bag 20 may also be directly expanded, but the bag opening mechanism 3 still needs to perform the opening action on the packaging bag 20 to completely expand the packaging bag 20.

[0057] The flapping device 9 includes a suspension bracket 91 installed on the side wall of the first rack 11, a fourth cylinder 92 vertically installed on the suspension bracket 91, and a flapping elastic rubber 93 arranged on the fourth cylinder 92 and used for flapping and jolting the packaging bag 20. A plurality of flapping devices 9 are provided, which are respectively located behind each material sorting and bag pulling machine 4 and material sorting machine 5. After the material sorting and bag pulling machine 4 and the material sorting machine 5 load the powder bag 40 and the material bag 50 into the packaging bag 20, it is necessary for the flapping device 9 to impact and push the packaging bag 20 to make the powder bag 40 and the material bag 50 tightly located in the packaging bag 20, so as to avoid the packaging bag 20 being unable to be closed and sealed.

[0058] In summary, when the utility model works, a plurality of packaging bags 20, powder bags 40, and material bags 50 are respectively placed into the bag bin 21, the first material bin 42, and the second material bin 52. After the equipment is started, the bag feeding mechanism 2 extracts the packaging bags 20 one by one and transfers them to the transposition and transfer mechanism 1, and then the clamping device 8 on the transposition and transfer mechanism 1 takes over and clamps the packaging bag 20; further, the transposition and transfer mechanism 1 transfers the packaging bag 20 to the bag opening mechanism 3. First, the two sides of the packaging bag 20 are brought closer and bent by the clamping jaw opening device A, and then the bag opening mechanism 3 grabs the two sides of the packaging bag 20 and pulls them outwards, and at the same time, gas is introduced into the packaging bag 20, so that the packaging bag 20 can be expanded, so as to facilitate the subsequent feeding of the powder bag 40 and the material bag 50 into the packaging bag 20; further, the transposition and transfer mechanism 1 continues to transfer the packaging bag 20 to the material sorting and bag pulling machine 4 and each material sorting machine 5 in turn, and the material sorting and bag pulling machine 4 and the material sorting machine 5 respectively feed the powder bag 40 and various material bags 50 into the packaging bag 20; further, the transposition and transfer mechanism 1 continues to transfer the packaging bag 20 to the sealing machine 6. Before that, it is necessary for the clamping jaw merging device B to push the clamping device 8 to make the opening of the packaging bag 20 closed, and then the sealing machine 6 heat-seals the opening of the packaging bag 20; further, the transposition and transfer mechanism 1 transfers the packaging bag 20 to the weighing machine 7. When the packaging bag 20 is above the weighing machine 7, the opening and clamping device 80 pushes the clamping device 8 to release the clamp, so that the packaged snail rice noodle packaging bag falls onto the weighing machine 7. Finally, the weighing machine 7 detects whether the packaging bag 20 is within the appropriate weight range, thereby judging whether there is less or more material in the packaging bag 20, and then transfers the qualified products out of the production line.
