Description

Technical Field

[0001] This utility model relates to the field of sealing machine technology, specifically a vacuum sealing machine with a movable heating wire. Background Technology

[0002] A vacuum sealer is a device commonly used for food packaging. It can vacuum and heat-seal the opening of bags containing food, thereby extending the shelf life of the food.

[0003] Existing vacuum sealing machines do not perform well when used continuously. Continuous heating causes the heating wire to overheat, resulting in premature sealing and the negative pressure inside the bag not reaching the expected level.

[0004] To address the aforementioned problems, a vacuum sealing machine with a movable heating wire is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a vacuum sealing machine with a movable heating wire, which solves the problem in the background technology that the vacuum sealing machine has poor continuous use effect, and the continuous heating causes the heating wire temperature to be too high, resulting in premature sealing and the negative pressure inside the bag not reaching the expected level.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a vacuum sealing machine with a movable heating wire, comprising a base, a sealing cap rotatably connected to the top of the base, an installation groove at the front end of the top of the base, a silicone seat for the heating wire disposed in the installation groove, air nozzles penetrating and fixedly connected to both sides of the silicone seat for the heating wire, air pipes fixedly connected to the ends of the two air nozzles, a slot at the top of the silicone seat for the heating wire, a heating wire disposed in the slot, limit components connected to both ends of the heating wire, the limit components being connected to the interior of the base, a fixing groove at the front end of the bottom of the sealing cap, a silicone bag for pressing fixedly connected in the fixing groove, a sealing sleeve fixedly connected to the middle of the top of the base, and a sealing groove at the bottom of the sealing cap.

[0007] By adopting the above technical solution, when the machine needs to be sealed, the air pump connected to the air nozzle blows air, causing the silicone seat of the heating wire to bulge, thereby driving the heating wire to rise and making the heating wire and the silicone of the pressure bag in close contact, thus ensuring the sealing effect.

[0008] As a further description of the above technical solution: the limiting component includes a buckle, the buckle is fixedly connected to both ends of the heating wire, a tension spring is sleeved on the outside of the buckle, a mounting post is fixedly connected to the end of the tension spring, and the top of the mounting post is fixedly connected to the inside of the base.

[0009] By adopting the above technical solution, the limiting component can conveniently fix and limit both ends of the heating wire, and also ensure that the heating wire can move up and down.

[0010] As a further description of the above technical solution: an exhaust structure is provided on the outside of the end of the trachea on the right side.

[0011] By adopting the above technical solution, the gas inside the silicone seat of the heating wire can be easily discharged through the exhaust structure.

[0012] As a further description of the above technical solution: an air pump is fixedly connected to the left side inside the base, and the output end of the air pump is fixedly connected to the air pipe on the left side.

[0013] By adopting the above technical solution, the air pump can blow air into the silicone seat of the heating wire through the air pipe.

[0014] As a further description of the above technical solution: both ends of the mounting groove are provided with slots, and both ends of the heating wire pass through the slots.

[0015] By adopting the above technical solution, the groove allows the heating wire to pass through the mounting groove.

[0016] As a further description of the above technical solution: the pressure bag silicone corresponds to the heating wire silicone seat.

[0017] By adopting the above technical solution, it is convenient for the silicone bag pressing material and the silicone heating wire seat to work together to ensure the sealing effect.

[0018] As a further description of the above technical solution: the sealing groove is located behind the fixed groove, and the sealing groove corresponds to the sealing sleeve.

[0019] By adopting the above technical solution, the sealing sleeve can be easily inserted into the sealing groove for sealing.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides a vacuum sealing machine with a movable heating wire. By optimizing the structure of the heating wire, the heating wire can move up and down. When the machine is vacuuming, the heating wire remains in a downward state and will not come into contact with the silicone of the bag. This ensures that the bag can be evacuated to the ideal negative pressure, avoiding the problem of the bag being sealed prematurely and the negative pressure inside the bag not reaching the expected level. This greatly increases the number of times the vacuum sealing machine can be used continuously. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] To further understand the contents of this utility model, a detailed description of this utility model will be provided with reference to the accompanying drawings.

[0025] Reference Figure 1-5 This utility model discloses a vacuum sealing machine with a movable heating wire, comprising a base 1, a cover 2 rotatably connected to the top of the base 1, an installation groove 3 at the front end of the top of the base 1, and a heating wire silicone seat 4 disposed within the installation groove 3. The heating wire silicone seat 4 is elastic and deformable, can be inflated, and is made of high-temperature resistant material. Air nozzles 5 are fixedly connected to both sides of the heating wire silicone seat 4, facilitating air intake and exhaust. Air pipes 8 are fixedly connected to the ends of both air nozzles 5, serving to transport airflow. A retaining groove 9 is provided at the top of the heating wire silicone seat 4, within which a heating wire 10 is disposed, serving to limit the movement of the heating wire 10. Limiting components are connected to both ends of the heating wire 10, and these limiting components are connected to the interior of the base 1. A fixing groove 15 is provided at the front end of the bottom of the cover 2, serving as an installation groove. A bag-pressing silicone 16 is fixedly connected within the fixing groove 15, working in conjunction with the heating wire silicone seat 4 to seal the bag. A sealing sleeve 18 is fixedly connected to the top center of the base 1, and a sealing groove 17 is opened at the bottom of the cover 2. A sealing ring (not shown in the figure) is provided in the sealing groove 17. The sealing sleeve 18 and the sealing ring in the sealing groove 17 form a vacuum chamber. The air pump (not shown in the figure) inside the base 1 is started. The air pump is connected to the vacuum chamber through a pipe (not shown in the figure) to extract the air in the chamber and the packaging bag.

[0026] Reference Figure 4The limiting component includes a buckle 13, which is fixedly connected to both ends of the heating wire 10. A tension spring 12 is sleeved on the outside of the buckle 13. A mounting post 11 is fixedly connected to the end of the tension spring 12. The top of the mounting post 11 is fixedly connected to the inside of the base 1. The limiting component can conveniently fix and limit both ends of the heating wire 10, and can also ensure that the heating wire 10 can move up and down.

[0027] Reference Figure 1-5 An exhaust structure 6 is provided on the outside of the end of the right-side air pipe 8. The exhaust structure 6 can be a solenoid valve or a snap-on exhaust structure. The exhaust structure 6 facilitates the discharge of gas from the heating wire silicone seat 4. An air pump 7 is fixedly connected to the left side of the base 1. The output end of the air pump 7 is fixedly connected to the left-side air pipe 8. The air pump 7 can blow air into the heating wire silicone seat 4 through the air pipe 8. Both ends of the mounting groove 3 have slots 14, and both ends of the heating wire 10 pass through the slots 14 to facilitate the passage of the heating wire 10 through the mounting groove 3. The pressure bag silicone 16 corresponds to the heating wire silicone seat 4, which facilitates the cooperation between the pressure bag silicone 16 and the heating wire silicone seat 4 to ensure a sealing effect. The sealing groove 17 is located behind the fixing groove 15 and corresponds to the sealing sleeve 18.

[0028] Working principle: The silicone seat 4 for the heating wire can be inflated, causing the heating wire 10 above it to rise. When the silicone seat 4 is inflated, air can be expelled through the exhaust structure 6 at the end of the air pipe 8 connected to the air nozzle 5 at one end. Under the action of the tension springs 12 at both ends, the heating wire 10 falls down. By controlling the air pump 7 connected to the air pipes 8 at both ends and the exhaust structure 6, the rising and falling of the heating wire 10 can be achieved. When the vacuum sealing machine is evacuating air, the heating wire silicone seat 4 remains in a downward state, and the heating wire 10 remains in a downward state under the action of the tension springs 12 on both sides, without contacting the bag-pressing silicone 16 on the machine; when the machine needs to seal, the air pump 7 connected to the left air nozzle 5 blows air, causing the heating wire silicone seat 4 to bulge, thereby driving the heating wire 10 to rise, so that the heating wire 10 and the bag-pressing silicone 16 are in close contact, thus ensuring the sealing effect; after the machine finishes working, the exhaust structure 6 at the end of the air pipe 8 connected to the right air nozzle 5 is opened, so that the gas inside the heating wire silicone seat 4 is discharged, the heating wire silicone seat 4 falls back, and at the same time the heating wire 10 also falls under the action of the tension spring 12.
