AI Technical Summary
When sealing food packaging equipment, juices and small pieces of food can easily remain at the seal, leading to the formation of false seams, low sealing yield, and affecting the shelf life of food.
Using ultrasonic generators and limiting components, the sealing head block vibrates the opening of the packaging bag, causing juice and small food particles to fall into the bag. Combined with a clamping component, it ensures accurate sealing position, using ultrasonic sealing to replace traditional hot melt sealing.
Reduce the amount of false seams in the seal, improve the quality of sealed products, ensure that food inside the packaging bag does not leak, and extend the shelf life of food.

DETAILED DESCRIPTION
[0017] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.
[0018] Please refer to Figure 1 The utility model provides a technical scheme: food packaging sealing equipment, including rack, ultrasonic wave generating assembly 2, clamping assembly 3 and limiting assembly 4. The rack is provided with a sealing box 1, the ultrasonic wave generating assembly 2 and the limiting assembly 4 are arranged in the sealing box 1, and the sealing box 1 can ensure the cleanliness of the ultrasonic wave generating assembly 2.
[0019] The ultrasonic generating assembly 2 comprises an ultrasonic transducer 21, a vibration head block 22, a matching pressing block 23 and a connecting column, the ultrasonic transducer 21 is fixedly connected with the vibration head block 22 through the connecting column, the ultrasonic transducer 21 converts electric signals into mechanical vibration, and the mechanical vibration is transmitted to the sealing position of the packaging bag to be sealed through the vibration head block 22. The vibration head block 22 and the matching pressing block 23 are on the same axis, and the vibration head block 22 and the matching pressing block 23 are close to or away from each other through the limiting assembly 4.
[0020] The limiting assembly 4 comprises a moving driving cylinder 41, a limiting guide rail 42, a first sliding block 43 and a second sliding block 44, the limiting guide rail 42 is arranged above the ultrasonic generating assembly 2 and is fixedly connected with the top of the sealing box 1, thereby saving the internal space of the sealing box 1. The first sliding block 43 is fixedly connected with the connecting column through a connecting seat, the bottom of the first sliding block 43 is fixedly connected with the top of the connecting seat, the connecting column passes through the connecting seat and is fixedly connected with the connecting seat, and the second sliding block 44 is fixedly connected with the matching pressing block 23. The first sliding block 43 and the second sliding block 44 are respectively limited to slide on the limiting guide rail 42, the moving driving cylinder 41 is arranged on the side, away from the second sliding block 44, of the first sliding block 43, the fixed end of the moving driving cylinder 41 is fixedly connected with the sealing box 1, the output end is fixedly connected with the first sliding block 43, and the moving driving cylinder 41 drives the first sliding block 43 to be close to or away from the second sliding block 44, so that the vibration head block 22 is controlled to be close to or away from the matching pressing block 23. The cooperation of the limiting sliding rail and the first sliding block 43 and the second sliding block 44 is to make the vibration head block 22 and the matching pressing block 23 move more accurately, because the size of the food packaging bag is small, the limiting assembly 4 can ensure that the vibration head block 22 and the matching pressing block 23 seal the packaging bag. In order for the ultrasonic generating assembly 2 to move more stably on both sides, the limiting assembly 4 is provided with two groups. The second sliding block 44 can be fixed in position on the limiting guide rail 42 according to actual conditions, or the second sliding block 44 can be driven to move by another driving cylinder in order to reduce the moving stroke of the first sliding block 43.
[0021] The packaging bag is arranged between the vibration head block 22 and the matching pressing block 23, during the sealing process, the vibration head block 22 vibrates the sealing position of the packaging bag, and the juice and fine food at the sealing position of the packaging bag are vibrated to fall into the packaging bag, and finally the sealing position of the packaging bag is sealed. Because the juice and fine food have fallen into the packaging bag due to vibration, the occurrence of false seams at the sealing position of the packaging bag is reduced, and the sealing yield is improved.
[0022] In order to fix the sealing position of the packaging bag, preferably, the clamping assembly 3 is in the same longitudinal plane with the vibrating sealing block 22 and the matching pressing block 23, and the clamping assembly 3 is arranged below the matching pressing block 23. The packaging bag loaded with food passes between the vibrating sealing block 22 and the matching pressing block 23 through the external conveying assembly, and the clamping assembly 3 clamps the packaging bag to ensure that both sides of the packaging bag do not exceed the sealing position of the vibrating sealing block 22 and the matching pressing block 23.
[0023] The working principle and use process of the utility model are as follows: the external conveying assembly passes the packaging bag loaded with food between the vibrating sealing block 22 and the matching pressing block 23, the clamping assembly 3 clamps the packaging bag, the vibrating sealing block 22 and the matching pressing block 23 are close to the packaging bag through the limiting assembly 4, the vibrating sealing block 22 works, because the vibrating sealing block 22 will vibrate when working, so the juice or small food at the sealing position of the packaging bag will fall into the packaging bag, and the vibrating sealing block 22 works to seal the sealing position of the packaging bag.
[0024] Finally, it should be pointed out that: the above-mentioned is only the preferred example of the utility model, and is not used for limiting the utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art, still can modify the technical scheme recorded in the foregoing embodiments, or equivalent replacement to part of the technical features.
