Description

Technical Field

[0001] The invention relates to the technical field of vacuum sealers, in particular to a self-cleaning waste-removing vacuum sealer. Background Art

[0002] The vacuum sealer puts food into a packaging bag, extracts the air in the packaging bag, and completes the sealing process after reaching a predetermined vacuum degree. It can have the following functions: 1. Vacuum the bag + seal it; 2. Seal the bag mouth directly; 3. Vacuum the bag + fill it with nitrogen or other gases + seal it. The vacuum sealers in the prior art basically only include vacuuming and sealing functions. In order to make the bag mouths of the vacuumed and sealed packaging bags have neat edges, some vacuum sealers will add a cutting mechanism to cut the packaging bags. The waste materials after cutting need to be taken away manually each time. If they are not taken away in time, the next cutting action will be affected, which will directly increase the workload of the operators. In addition, for some packaging bags filled with liquids, it is inevitable that some liquids will overflow into the vacuum tank during vacuum sealing. If they are not cleaned in time, they will accumulate in the vacuum tank. Over time, odors will be emitted and stains will be formed in the vacuum tank. If they are frequently cleaned by hand, the workload of the operators will be directly increased. In view of this situation, it is urgent to solve it. Summary of the invention

[0027] The operating steps of the present invention are:

[0028] 1. The positions of the lower seat 12 and the upper cover 25 correspond to each other, and the packaging bag is placed between the lower seat 12 and the upper cover 25. The first lifting drive motor 31 causes the upper cover 25 to be pressed down to the lower seat 12 to achieve the closing;

[0029] 2. The bag opening of the packaging bag is evacuated in the vacuum chamber 24, and then the bag opening of the packaging bag is heat-sealed by the upper heat pressing strip 38 and the lower heat pressing strip 16;

[0030] 3. After the heat sealing is completed, the cutting drive motor 26 prompts the cutting knife 40 to cut the bag mouth of the packaging bag neatly;

[0031] 4. The first lifting drive motor 31 causes the upper cover 25 to rise and reset;

[0032] 5. After the second lifting drive motor 32 drives the material brush 29 to rise to a predetermined height, the third rotary drive motor 33 drives the second lifting drive motor 32 and the material brush 29 to rotate a predetermined angle, and the material brush 29 moves from the upper side of the vacuum tank 24 to the waste collection tray 19, thereby dropping the waste on the upper surface of the lower seat body 12 into the waste collection tray 19; then, the third rotary drive motor 33 drives the material brush 29 to rotate and reset to a side parallel to the lower seat body 12, and the second lifting drive motor 32 drives the material brush 29 to descend and reset;

[0033] 6. The two first rotary drive motors 11 synchronously drive the U-shaped connecting arm 23 to flip 180 degrees, so that the sponge cleaning strip 20 is located at one side of the feeding port, and the second linear motors 10 on both sides drive the two first rotary drive motors 11 to move a predetermined distance toward the feeding port;

[0034] 7. After the first linear motor 17 drives the lower seat 12 to move a predetermined distance in the feeding direction, the second rotary drive motor 22 drives the elastic connecting rod 21 to rotate 90° so that the elastic connecting rod 21 extends into the vacuum tank 24 and contacts the bottom of the inner cavity of the vacuum tank 24;

[0035] 8. The first linear motor 17 drives the lower seat 12 to continue to move in the feeding direction. During the movement, the inner cavity bottom and side walls of the vacuum tank 24 are wiped clean by the sponge cleaning strip 20;

[0036] 9. After completing the wiping action, the second rotary drive motor 22 drives the elastic connecting rod 21 to return to its original position and rotate 90° to allow the sponge cleaning strip 20 to extend out of the vacuum groove 24; the first linear motor 17 drives the lower seat 12 to return to its original position; the two first rotary drive motors 11 synchronously drive the U-shaped connecting arm 23 to return to its original position and flip 180°, and then the second linear motors 10 on both sides drive the two first rotary drive motors 11 to return to their original positions; and the operation is repeated.

[0037] After completing the vacuuming and heat sealing, the present invention can also cut the bag mouth of the packaging bag. After the cutting is completed, the waste can be moved to the waste collection tray, and then the vacuuming groove can be wiped with a cleaning brush. There is no need to manually clean the vacuuming groove or manually remove the cut waste, which saves the workload of the operators.

[0038] The above-mentioned embodiment only expresses one implementation mode of the present invention, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
