Description

Technical Field

[0001] The utility model belongs to the technical field of packaging bag sealing, and particularly relates to a packaging bag sealing device. Background Art

[0002] There are three methods for sealing packaging bags, namely heat sealing, ironing sealing, and mechanical equipment sealing. Heat sealing: Heat a saw blade with fire and roll up the plastic film. You can also take a stick, first roll the bag to be sealed in a circle, and then heat it with a small fire. It can be sealed firmly and the bag will not be damaged by the heat. Ironing sealing: Turn on the iron. When it reaches an appropriate temperature, place an iron plate or a hard object below and press it with the back of the iron. However, when using an iron to seal, attention should be paid to the temperature and the sealing speed. Mechanical equipment sealing: For a large number of plastic packaging bags, if you want to improve the sealing speed, a sealing machine can be used for sealing. For ordinary single-layer plastic packaging bags, a foot-operated sealing machine can be used for sealing. For multi-layer composite plastic packaging bags, such as PET plastic packaging bags, usually a high temperature of 200 degrees is required to seal the bag well.

[0003] From the perspective of the prior art, the common packaging welding technology uses a combination of a high-temperature welding plate and a telescopic rod to seal the packaging bag. Since the telescopic rod drives the welding plate for welding unstably, it is easy to cause unsafe sealing. Moreover, the existing sealing equipment has high energy consumption and requires a motor to drive the rebound. Therefore, a packaging bag sealing device is needed.

[0004] It should be noted that the above content belongs to the technical cognitive scope of the utility model person and does not necessarily constitute the prior art. Content of the Utility Model

[0005] The purpose of the utility model is to solve the disadvantages of unsafe, unstable and high energy consumption in the existing packaging bag sealing in the prior art, and to propose a packaging bag sealing device.

[0006] To achieve the above object, the present utility model provides a packaging bag sealing device, including a motor and a mounting plate. The mounting plate has a square structure, and one side of the mounting plate is rotatably connected to a rotating shaft. One end of the rotating shaft away from the mounting plate is installed with a rotating disc. The rotating disc has a diamond structure. The middle position of the rotating disc is fixedly connected to the rotating shaft, and both sides of the rotating disc are rotatably connected to connecting rods. One end of each of the two connecting rods is rotatably connected to the rotating disc, and the other ends of the connecting rods are respectively rotatably connected to an upper moving plate and a lower moving plate. The upper moving plate is larger than the lower moving plate. On one side of the upper moving plate close to the rotating disc, two outer sliding rods are symmetrically installed, and on one side of the lower moving plate away from the rotating disc, two inner sliding rods are symmetrically installed. On one side of the two outer sliding rods away from the upper moving plate, outer bases are installed. One end of the two inner sliding rods away from the lower moving plate is fixedly connected to inner bases. A sliding sleeve is sleeved on the middle positions of the outer sliding rods and the inner sliding rods, and the sliding sleeve is fixedly connected to the mounting plate through a fixing rod.

[0007] Preferably, two springs are installed between the upper moving plate and the lower moving plate. The two springs are symmetrically installed. One end of each of the two springs is fixedly connected to the upper moving plate, and the other end of the spring is fixedly connected to the lower moving plate.

[0008] Preferably, welding platforms are installed on the opposite sides of the outer base and the inner base. The two welding platforms are symmetrically installed. A heating pipe is installed on the welding platform of the inner base.

[0009] Preferably, an auxiliary block is installed between the rotating disc and the mounting plate. The auxiliary block is fixedly connected to the rotating shaft, and an impact block is installed on one side of the auxiliary block.

[0010] Preferably, a motor is installed on one side of the mounting plate away from the rotating shaft. The outer shell of the motor is fixedly connected to the mounting plate, and the output end of the motor passes through the mounting plate and is fixedly connected to the impact block. Both the impact block and the auxiliary block have an arc-shaped structure and one side is convex. The impact block is close to the auxiliary block.

[0011] The packaging bag sealing device provided by the present utility model can bring the following beneficial effects:

[0012] 1. In the present utility model, the motor is used to drive the impact block to rotate. Due to the special shapes of the impact block and the auxiliary block, when the convex part of the impact block pushes the auxiliary block to rotate, the rotating shaft rotates a certain angle, driving the rotating disc to rotate. The rotation of the rotating disc causes the upper moving plate and the lower moving plate to move in the vertical direction. By using the spring rebound, the actions of the upper moving plate and the lower moving plate approaching and separating from each other are realized. When the upper moving plate and the lower moving plate approach each other, due to the combination of the outer sliding rods and the inner sliding rods, the two welding platforms are separated. When the upper moving plate and the lower moving plate move away from each other, due to the combination of the outer sliding rods and the inner sliding rods, the two welding platforms approach each other, achieving the effect of sealing the packaging bag.

[0021] Embodiment 1

[0022] As Figures 1-4As shown in the figure, a packaging bag sealing device proposed by the utility model includes a motor 18 and a mounting plate 1. The mounting plate 1 has a square structure, and a rotating shaft 2 is rotatably connected to one side of the mounting plate 1. A rotating disk 3 is installed at the end of the rotating shaft 2 away from the mounting plate 1. The rotating disk 3 has a diamond structure, and the middle position of the rotating disk 3 is fixedly connected to the rotating shaft 2. Connecting rods 4 are rotatably connected to both sides of the rotating disk 3. One end of the two connecting rods 4 is rotatably connected to the rotating disk 3, and the other ends of the connecting rods 4 are respectively rotatably connected to an upper moving plate 5 and a lower moving plate 6. The upper moving plate 5 is larger than the lower moving plate 6. Two outer sliding rods 10 are symmetrically installed on the side of the upper moving plate 5 close to the rotating disk 3, and two inner sliding rods 11 are symmetrically installed on the side of the lower moving plate 6 away from the rotating disk 3. An outer base 15 is installed on the side of the two outer sliding rods 10 away from the upper moving plate 5, and an inner base 14 is fixedly connected to the ends of the two inner sliding rods 11 away from the lower moving plate 6. A sliding sleeve 12 is sleeved on the middle positions of the outer sliding rod 10 and the inner sliding rod 11, and the sliding sleeve 12 is fixedly connected to the mounting plate 1 through a fixing rod 13.

[0023] Among them, two springs 9 are installed between the upper moving plate 5 and the lower moving plate 6. The two springs 9 are symmetrically installed. One end of the two springs 9 is fixedly connected to the upper moving plate 5, and the other end of the spring 9 is fixedly connected to the lower moving plate 6.

[0024] Among them, welding platforms 16 are installed on the opposite sides of the outer base 15 and the inner base 14. The two welding platforms 16 are symmetrically installed. A heating pipe 17 is installed on the welding platform 16 on the inner base 14.
