Description

Technical Field

[0001] The utility model relates to the technical field of food packaging, in particular to a sealing element installation device for flexible packaging of liquid food. Background Technique

[0002] Flexible food packaging, with its characteristics of being lightweight, flexible and diverse, has become the mainstream choice for modern food packaging. It is usually made of multi-layer composite plastic films, with excellent sealing and barrier properties, which can effectively protect food from external pollution and extend the shelf life. Flexible food packaging is not only convenient for carrying and storing, but also adapts to various food processing and transportation needs, and can be seen in everything from daily snacks to frozen foods. At the same time, with the improvement of environmental awareness, more and more flexible food packaging begins to use recyclable or biodegradable materials, striving to reduce the environmental burden while protecting food.

[0003] Food soft packaging bags are generally sealed by hot pressing. The hot pressing seal consists of a hot pressing plate and a heating component. After long-term use, a large amount of melted plastic will accumulate on the hot pressing plate, affecting the hot pressing seal effect. The hot pressing plate needs to be replaced frequently. The hot pressing plate is generally fixed to the encapsulation clamping block by screws. When replacing the hot pressing plate, workers need to loosen the screws one by one and then loosen the heating component, resulting in a slow replacement speed. For this reason, a sealing element installation device for flexible packaging of liquid food is proposed. Content of the Utility Model

Specific implementation manner

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] As Figure 1 and Figure 2 shown, the present utility model provides a technical solution for a sealing member installation device for liquid food flexible packaging, including a mounting base 1. Mounting through-holes 2 are provided at the four corners of the mounting base 1. A clamping block seat 3 is provided on the mounting base 1. An encapsulation clamping block 4 is provided on the clamping block seat 3. A heating assembly 5 is provided on the encapsulation clamping block 4. A hot pressing mechanism 6 is provided inside the encapsulation clamping block 4. By the combined use of the heating assembly 5 and the hot pressing mechanism 6, it is convenient for users to quickly remove and replace the hot pressing plate 601.

[0023] As Figure 2 and Figure 3 shown, the heating assembly 5 includes a telescopic ejector rod 506 movably installed inside the encapsulation clamping block 4. A winding disc 504 is fixedly installed on the telescopic ejector rod 506. A first spring 505 is sleeved on the telescopic ejector rod 506. One end of the telescopic ejector rod 506 is fixedly installed with a rotating shaft 507. The other end of the telescopic ejector rod 506 is movably installed with a fixing frame body 502. An electric heating plate 501 is fixedly installed on the fixing frame body 502. A rotating connection groove 503 is provided on the fixing frame body 502. The telescopic ejector rod 506 is movably installed on the fixing frame body 502 through the rotating connection groove 503. An activity groove is provided on the encapsulation clamping block 4. The telescopic ejector rod 506 is movably installed inside the encapsulation clamping block 4 through the activity groove.

[0024] Specifically, the first spring 505 can push the winding disk 504 to move forward, thereby driving the telescopic top rod 506 to move forward. After the telescopic top rod 506 moves forward, it will drive the fixed frame 502 to move forward, thereby pressing the electric heating plate 501 against the hot pressing plate 601, so that the hot pressing plate 601 can be quickly heated.

[0025] like Figure 2 , Figure 4 and Figure 5 As shown, the hot pressing mechanism 6 includes a hot pressing plate 601 connected to the packaging clamp 4, a limiting support leg 602 is fixedly installed on the hot pressing plate 601, a mechanism shell 604 is fixedly installed in the packaging clamp 4, a spring seat 607 is movably installed in the mechanism shell 604, a second spring 606 is provided on one side of the spring seat 607, a limiting latch 603 is fixedly installed on the other side of the spring seat 607, a steel wire rope 605 is connected to the spring seat 607, a bayonet is provided on the limiting support leg 602, the limiting latch 603 is embedded in the limiting support leg 602 through the bayonet, a bayonet is provided on the limiting support leg 602, the limiting latch 603 is embedded in the limiting support leg 602 through the bayonet, a connecting port is provided on the packaging clamp 4, and the limiting support leg 602 is connected to the packaging clamp 4 through the connecting port.

[0026] Specifically, the winding disk 504 can be driven to rotate by the rotating shaft 507. After the winding disk 504 rotates, it will reel in the wire rope 605. After the wire rope 605 is reeled in, it will pull the limit pin 603 to disengage from the limit support leg 602. After the limit pin 603 is disengaged from the limit support leg 602, the limit support leg 602 can be pulled out, so that the hot pressing plate 601 can be quickly removed and replaced. After the hot pressing plate 601 is replaced, the rotating shaft 507 can be loosened to allow the limit pin 603 to be re-embedded in the limit support leg 602, so that the new hot pressing plate 601 can be quickly fixed.

[0027] Working principle: When replacing the hot pressing plate 601, the rotating shaft 507 can be rotated. After rotating the rotating shaft 507, it will drive the telescopic ejector rod 506 to rotate. After the telescopic ejector rod 506 rotates, it will drive the winding disc 504 to rotate. After the winding disc 504 rotates, it will wind the steel wire rope 605. Since one end of the steel wire rope 605 is fixed on the spring seat 607 and the other end of the steel wire rope 605 is fixed on the winding disc 504, after the steel wire rope 605 is wound, it will pull the limit pin 603 out of the limit support leg 602. After the limit pin 603 is separated from the limit support leg 602, the limit support leg 602 can be pulled out, so that the hot pressing plate 601 can be quickly removed and replaced. After the replacement of the hot pressing plate 601 is completed, the rotating shaft 507 can be released. Since one end of the second spring 606 is connected to the spring seat 607 and the other end of the second spring 606 is connected to the end of the mechanism housing 604, after the rotating shaft 507 is released, the second spring will drive the limit pin 603 on the spring seat 607 to move forward, so that the limit pin 603 is inserted into the limit support leg 602 to quickly fix the new hot pressing plate 601. Since one end of the first spring 505 is connected to the winding disc 504 and the other end of the first spring 505 is connected to one end of the movable groove, after the hot pressing plate 601 is quickly fixed, the first spring 505 can push the winding disc 504 forward. After the winding disc 504 moves forward, it will drive the telescopic ejector rod 506 to move forward. After the telescopic ejector rod 506 moves forward, it will drive the fixed frame 502 to move forward. After the fixed frame 502 moves forward, it will press the electric heating plate 501 against the hot pressing plate 601, so that the hot pressing plate 601 can be quickly heated.
