Description

Technical Field

[0001] The utility model relates to the technical field of packaging and sealing machines, in particular to a sealing machine used for material packaging bags. Background Art

[0002] The sealing machine used for material packaging consists of two parts: packaging equipment and sealing equipment. The packaging equipment opens the packaging bag to fill the material, while the sealing equipment seals the packaging bag containing the material. After the packaging bag is filled with material, it will be transported by the conveyor belt to the bottom of the sealing equipment for sealing. The process is fully automated.

In severe cases, the sealing operation of the packaging bags may even be interrupted, affecting the sealing efficiency. Utility Model Content

[0021] To facilitate the understanding of this application, the following will provide a more comprehensive description of this application with reference to the relevant attached drawings. Embodiments of this application are shown in the attached drawings. However, this application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the disclosure of this application more thorough and comprehensive.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which this application belongs. The terms used in the description of this application herein are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0023] Please refer to Figures 1-3 , a sealing machine for material packaging bags of the present utility model includes a packaging machine 1, a first conveyor belt 2, and a sealing device 3 provided outside the first conveyor belt 2. A transmission member 4 is disposed around the outside of the packaging machine 1 and the sealing device 3. The transmission member 4 is perpendicular to the first conveyor belt 2. Limiting members 5 are equidistantly arranged on the outside of the transmission member 4. Two adjacent limiting members 5 cooperate to form a limiting wrap.

[0024] Please refer to Figure 1 , the packaging machine 1 includes a support portion 11, a feeding end 12, a feeding hopper 13, and a discharging hopper 14. The feeding end 12 is fixedly connected to the top of the front surface of the support portion 11. The feeding hopper 13 is fixedly connected to the center of the top of the feeding end 12. The discharging hopper 14 is fixedly connected to the center of the bottom of the feeding end 12.

[0025] Please refer to Figure 1 , the first conveyor belt 2 is disposed at the bottom of the front surface of the support portion 11 and is perpendicular to the support portion 11. The sealing device 3 is fixedly connected to the back surface of the first conveyor belt 2 and is perpendicular to the first conveyor belt 2.

[0026] Please refer to Figure 2 , the transmission member 4 includes a slide rail 41 and a second conveyor belt 42. The slide rail 41 is fixedly connected to the outside of the support portion 11 and the sealing device 3. The slide rail 41 surrounds the support portion 11 and the sealing device 3. There are two second conveyor belts 42, which are slidably connected to the inside of the slide rail 41. The two second conveyor belts 42 are symmetrically distributed with the center of the slide rail 41 as the origin. The second conveyor belt 42 is a plate chain conveyor belt. The second conveyor belt 42 is convenient to move inside the slide rail 41. The packaging bags conveyed by the first conveyor belt 2 can push the limiting members 5 and the second conveyor belt 42 along the slide rail 41 to move synchronously with the packaging bags through their own gravity to form a wrapping limit. At the same time, the plate chain surface of the second conveyor belt 42 can also provide a supporting surface for the installation and fixation of the limiting members 5 to ensure the fixing strength of the limiting members 5.

[0027] Please refer to Figure 2, the limiting member 5 includes a rod body 51, a rod head 52 and a connecting portion 53. There are two rod bodies 51, which are respectively fixedly connected to the surfaces of the two second conveyor belts 42. The connecting portion 53 is fixedly connected between the two rod bodies 51 and is perpendicular to the rod body 51. The two rod bodies 51 of the limiting member 5 respectively correspond to the two second conveyor belts 42. Only when the two rod bodies 51 are simultaneously subjected to the thrust of the packaging bag, the two second conveyor belts 42 will move simultaneously to make the limiting member 5 move and wrap around the outside of the packaging bag to form a limit. The setting of the forces on the two rod bodies 51 limits the force direction when the limiting member 5 and the second conveyor belt 42 slide along the slide rail 41. When the packaging bag filled with materials is poured on the surface of the limiting member 5, the force on the limiting member 5 will not cause the second conveyor belt 42 to move largely and affect the mating positioning with the packaging bag outside the first conveyor belt 2.

[0028] Please refer to Figure 2 , the rod head 52 is integrally formed at one end of the rod body 51 away from the slide rail 41. There are two rod heads 52, which are symmetrically distributed with the center of the rod body 51 as the origin. The two rod heads 52 are bent towards both sides of the rod body 51 respectively. The shapes of the rod body 51 and the rod head 52 are both isosceles trapezoids. The rod heads 52 on the outside of adjacent two limiting members 5 can cooperate to wrap the packaging bag and limit the packaging bag between the two limiting members 5, increasing the stability of the packaging bag during transportation outside the first conveyor belt 2. The setting of the isosceles trapezoids of the rod body 51 and the rod head 52 can change the force direction of the rod body 51. When the packaging bag is poured on the surface of the rod body 51, the force on the limiting member 5 will not cause the second conveyor belt 42 to move largely and affect the mating positioning with the packaging bag outside the first conveyor belt 2, ensuring the stability of the cooperation between the limiting member 5 and the packaging bag. Only when the first conveyor belt 2 transports the packaging bag and moves, and the rod body 51 receives the lateral thrust of the packaging bag, the limiting member 5 will be stressed to make the second conveyor belt 42 slide outside the slide rail 41 and be synchronized with the first conveyor belt 2 to maintain the limit of the limiting member 5 on the packaging bag.
