Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of heat sealing mechanisms, in particular to a heat sealing mechanism for processing packaging bags. Background Art
[0002] Packaging bags are bags used to package various items, making them easy to transport and store during production and distribution. They are widely used in daily life and industrial production. There are many types of packaging bags. Based on their appearance, they can be divided into vest bags, straight bags, three-dimensional bags, square-bottom bags, sealable bags, adhesive strip bags, and special-shaped bags. Based on their shape, they can be divided into three-side seal bags (palm-seal bags), back-seal bags, gusset bags (organ bags), and stand-up bags.
[0003] Heat sealing the bags creates a tightly sealed package to prevent bacteria from entering, ensuring the quality and hygiene of the contents;
[0004] Existing heat-sealing mechanisms often fail to position the packaging bag during use. This can cause the bag to shift during the heat-sealing process due to pressure or temperature fluctuations during the heat-sealing process, resulting in incomplete adhesion of the heat-sealed area. This directly affects the sealing of the package, making the contents susceptible to contamination or damage from the external environment. Furthermore, after the heat seal is completed, if there is no ejection mechanism to eject the bag from the heat-sealing heating table, the bag may continue to adhere to the heating table due to residual heat. This not only affects the integrity of the bag, but may also cause contamination or damage to the next bag during heat sealing. Therefore, a heat-sealing mechanism for packaging bag processing is proposed to address the above issues. Utility Model Content

[0030] The working principle of the above embodiment is:
[0031] 1. In actual use, when the staff needs to heat-seal the packaging bag, they can first place the packaging bag on the heating seat 18 so that it is located below the heat-sealing knife 152. Then, the staff can control the first electric push rod 12 to make the push rod drive the connecting block 13 to move downward. During the downward displacement of the connecting block 13, the guide column 14 can be driven to cause the mounting platform 15 to move downward.

Under the action of the fixing component 2, the packaging bag can be effectively fixed, avoiding the occurrence of deviation during the heat sealing process. When the heat sealing of the packaging bag is completed, the staff can control the third electric push rod 17 to make the push rod produce a displacement effect. During the displacement of the third electric push rod 17, the packaging bag after heat sealing can be ejected, thereby avoiding the occurrence of adhesion between the packaging bag and the heating seat 18.
[0032] 2. In actual use, the staff can place the packaging bag on the support seat 35, and then the staff can control the mounting platform 15 to drive the mounting frame 21 and the fixing platform 22 to fix the mouth of the packaging bag, thereby avoiding the occurrence of displacement during the heat sealing process; when the mounting platform 15 drives the fixing platform 22 to fix the mouth of the packaging bag, it can also drive the fixing seat 41 to cause the sleeve rod 42 and the clamping rod 44 to move downward, and during the downward displacement of the clamping rod 44, it can drive the clamping platform 45 to move downward. The clamping platform 45 is displaced until it contacts the middle of the packaging bag. The clamping platform 45 drives the clamping rod 44 and the sliding rod 43 to slide upward in the sleeve rod 42, and can compress the support spring 46 so that the support spring 46 can provide the clamping rod 44 with a reverse elastic force, so that the clamping platform 45 can fix the packaging bag while avoiding overpressure on it. When the heat sealing is completed, the staff can control the servo motor 31 to drive the first conveyor belt 34 and the support seat 35 to convey the packaging bag to the hopper 19, thereby achieving the effect of collecting the packaging bag.
