Description

Technical Field

[0001] The utility model relates to the technical field of degassing packaging machines, in particular to an automatic degassing packaging machine. Background Art

[0002] The packaging machine is designed for packaging products. For granular products, they need to be sealed after vacuuming. If granular products are not vacuumed, the packaging bags will be filled with air. Once squeezed during transportation, the packaging bags will easily explode.

[0003] When the packaging machine is filling granular products, it will first open the bag mouth through the mobile bracket, and then start to fill the product into the bag. However, in this process, because the filling port is often located at the bag mouth, and the product falls, the falling product collides with the product that has already fallen into the bag. Especially for powdered products, it is easy to splash and rise after falling, and then fly out from the bag mouth, causing product waste. Utility Model Content

A push plate 11 is built into the body 10, and a connecting frame 6 is installed on the push plate 11. The other end of the connecting frame 6 is installed on the corresponding screw rod 4 through a thread. When in use, the second linear motor 2 can lift and lower the height of the push plate 11, thereby adjusting the height of the push plate 11, so that the height of the push plate 11 can be adjusted according to the size of the packaging bag, so that the position of the push plate 11 can be adapted according to the size of the packaging bag; when the push plate 11 extends into the bag opening of the packaging bag, as the screw rod 4 rotates, the push plate 11 can be extended outward, thereby resting on the inner wall of the packaging bag, so that the packaging bag can be propped up; in actual use, rubber pads are installed along the edges of the push plate 11 to provide buffering protection for the process of the push plate 11 propping up the packaging bag.

[0030] like Figure 3 and Figure 5 As shown, a material tank 15 is arranged on the top of the support frame 1, and at least three spaced support legs 16 are installed along the bottom edge of the material tank 15, and the bottom of the support leg 16 is fixed on the support frame 1 to provide support for the material tank 15 on the support frame 1.

[0031] A feeding pipe 32 is installed on the top of the material tank 15, and a discharge pipe 17 is connected to the bottom of the material tank 15. A solenoid valve 25 is installed on the discharge pipe 17 to control the discharge of the material. The bottom of the discharge pipe 17 passes through the support frame 1 and is connected to a telescopic hose 18, and an injection head 19 is connected to the bottom of the telescopic hose 18, so that the injection head 19 can be lifted and moved along the axial direction of the discharge pipe 17;

[0032] An upwardly bent L-shaped rod 23 is connected to both sides of the top of the injection head 19, and a slot 24 is provided on the top of the L-shaped rod 23. A connecting rod 22 is rotatably connected inside the slot 24. The other end of the connecting rod 22 is rotatably installed in the U-shaped seat 21, and the U-shaped seat 21 is fixed on the slider of the first linear motor 20, and the slide rail of the first linear motor 20 is fixed on the inner top of the support frame 1, and the slide rail of the first linear motor 20 is arranged along the radial direction of the discharge pipe 17. After the packaging bag is propped up, the slider of the first linear motor 20 will be at the position of the slide rail of the first linear motor 20 close to the discharge pipe 17, that is, the injection head 19 will extend from the circular groove 8 to the bottom of the packaging bag. At this time Start pouring the material. As the material is continuously added, the slider of the first linear motor 20 starts to move away from the discharge pipe 17, that is, it starts to pull the end of the connecting rod 22 away from the discharge pipe 17. As the first linear motor 20 operates, the injection head 19 starts to be slowly lifted upward from the packaging bag, that is, the injection head 19 rises with the amount of material added to the packaging bag. In this way, during the process of loading the material into the packaging bag, the injection head 19 can always maintain a distance close to the top of the material in the packaging bag, so as to reduce the falling distance of the material to reduce the impact of the material when it falls, thereby preventing the material from being lifted up after being loaded into the packaging bag, causing material waste or affecting the surrounding environment.

[0033] As materials are continuously added into the packaging bag, a vacuum pump 12 is installed on one of the push plates 11, a vacuum pipe 13 is installed at the bottom of the vacuum pump 12, and an exhaust pipe 14 is installed on the top of the vacuum pump 12 to exhaust the air in the packaging bag to prevent excessive air in the packaging bag during subsequent sealing, which may easily cause the packaging bag to be damaged due to squeezing during transportation, thereby causing the material to scatter.

[0034] It should be further explained that a fixing frame 26 is installed on the support plate 7, and the other end of the fixing frame 26 is fixed to the strip seat 3 to fix the support plate 7 to prevent one of the push plates 11 from moving with the support plate 7 during use, thereby affecting the alignment of the circular groove 8 and the injection head 19.
