Technical Field

[0001] The utility model belongs to the technical field of packaging bag processing, and in particular relates to a feeding device of an automatic bottom sealing machine for three-dimensional packaging bags. Background Art

[0002] Three-dimensional packaging bags are widely used in packaging in food, medical and other industries.

[0003] During the processing of three-dimensional packaging bags, the three-dimensional packaging bags need to be stretched out and then the bottom needs to be sealed. The traditional method of sealing the bottom is to manually stretch the three-dimensional packaging bags onto the support frame, and then seal the bottom through the bottom ironing device and then remove it manually. This is not only inefficient, but also wastes a lot of manpower.

[0004] The existing Chinese patent with announcement number CN214239752U discloses a feeding device of an automatic bottom sealing machine for three-dimensional packaging bags, including a base, a screw rod is vertically arranged on the base, the screw rod is threadedly connected to a fixed frame slidably mounted on the base, a transverse slide rail is arranged on the fixed frame, a movable plate that can move along the slide rail is arranged on the slide rail, the movable plate is connected to a No. 1 cylinder that controls its movement, a storage box for three-dimensional packaging bags is mounted on one end of the fixed frame, the storage box passes through from top to bottom and has blocks around its bottom that prevent the three-dimensional packaging bags from falling down, a slide groove is arranged on the movable plate along the direction of the slide rail, a slider is slidably provided in the slide groove, the slider is connected to a No. 2 cylinder that controls its sliding along the slide groove, the fixed frame A No. 1 suction pipe with a suction cup is provided near the end of the storage box, and the No. 1 suction pipe is connected to a No. 3 cylinder for controlling its up and down movement, and a bag opening device is provided on the movable plate away from the slide slot end, and the bag opening device includes a support plate for supporting the bag opening, and the support plate includes a top plate parallel to the movable plate and two side plates vertically connected between the movable plate and the top plate and parallel to the slide slot, and a No. 2 suction pipe with a suction cup is symmetrically provided below the movable plate and above the top plate, and the No. 2 suction pipe is connected to a No. 4 cylinder for controlling its up and down movement and fixed on the fixed frame, and a No. 1 clip device for pressing the upper and lower sides of the bag opening is also provided on the movable plate and the top plate, and a No. 2 clip device for pressing the other two sides of the bag opening is symmetrically provided on the two side plates.

[0005] Regarding the above-mentioned related technologies, the inventors found that there are at least the following problems in this technology: during the feeding process of the packaging bag, there is a lack of a limiting structure, which makes the packaging bag easily offset, and when using a straw to suck open the bag mouth, the straw is a certain distance away from the packaging bag, which easily leads to bag opening failure. Utility Model Content

[0023] See also Figure 1-4 The present invention provides a feeding device for an automatic bottom sealing machine for three-dimensional packaging bags, comprising a base frame 1. Mounting plates 17 are fixedly connected to the four corners of the bottom of the base frame 1. Mounting holes 18 are provided on the mounting plates 17. The base frame 1 can be fixed to the bottom sealing machine by arranging the mounting plates 17 and the mounting holes 18. Rollers 2 are rotatably mounted on both ends of the base frame 1. A motor 14 is fixedly mounted on one side of the base frame 1. The output end of the motor 14 is fixedly connected to one of the rollers 2. A conveyor belt 3 is commonly sleeved on the two rollers 2. By arranging the motor 14, the rollers 2, and the conveyor belt 3, a vertical packaging bag can be placed upside down on the conveyor belt 3. Starting the motor 14 drives the rollers 2 to rotate, which in turn drives the conveyor belt 3 to rotate, causing the conveyor belt 3 to feed the vertical packaging bag.

[0024] The two ends of the screw 4 are fixedly connected to the conveyor belt 3, and the other end of the screw 4 is rotatably connected to the limit plate 6. The two limit plates 6 are symmetrically distributed above the conveyor belt 3. The limit plate 6 is fixedly connected to the side of the screw 4 close to the screw 4 with a guide rod 15. The guide rod 15 is parallel to the screw 4. The guide rod 15 slides through the side wall of the base frame 1. Through the arrangement of the handle 5, screw 4 and limit plate 6, when transporting the packaging bag, the handle 5 can be manually rotated to make the handle 5 drive the screw 4 to rotate, and the screw 4 drives the limit plate 6 to move along the length direction of the screw 4. The spacing between the two limit plates 6 is adjusted to a suitable position to limit the vertical packaging bag to avoid displacement during the feeding process of the vertical packaging bag.

[0025] Both sides of the top of the chassis 1 are fixedly connected to support seats 7, and a cylinder 8 is fixedly installed on the support seat 7. The piston end of the cylinder 8 is fixedly connected to a suction plate 9. The side of the suction plate 9 close to the cylinder 8 is fixedly connected to a limit rod 16. The limit rod 16 slides through the side wall of the chassis 1. There are several suction nozzles 10 distributed in a matrix on the surface of the suction plate 9. An air pump 11 is fixedly installed at the bottom of the chassis 1. The inlet end of the air pump 11 is fixedly connected to a three-way pipe 12. A suction pipe 13 is connected between the three-way pipe 12 and the two suction plates 9. One end of the tube 13 located between the base frame 1 and the suction plate 9 is a corrugated hose. Through the arrangement of the cylinder 8, suction plate 9, suction nozzle 10, air pump 11, tee pipe 12 and suction pipe 13, when the vertical packaging bag is transferred between the two suction plates 9, the cylinder 8 can be started to drive the suction plate 9 close to the vertical packaging bag, and then the air pump 11 can be started to suck air into the suction plate 9, so that the two suction plates 9 respectively suck the two sides of the vertical packaging bag, and then the cylinder 8 can be started to drive the two suction plates 9 to separate, thereby opening the bag mouth of the vertical packaging bag and improving the bag opening efficiency.

[0026] The working principle and use process of the utility model are as follows: First, through the setting of the motor 14, the roller 2 and the conveyor belt 3, the vertical packaging bag can be placed upside down on the conveyor belt 3, and the motor 14 is started to drive the roller 2 to rotate, so that the roller 2 drives the conveyor belt 3 to rotate, so that the conveyor belt 3 feeds the vertical packaging bag. Through the setting of the handle 5, the screw 4 and the limit plate 6, when the packaging bag is transported, the handle 5 can be manually rotated to drive the screw 4 to rotate, so that the screw 4 drives the limit plate 6 to move along the length direction of the screw 4, and the distance between the two limit plates 6 is increased. Adjust to the appropriate position to limit the stand-up packaging bag to avoid deviation during the feeding process of the stand-up packaging bag. Through the arrangement of the cylinder 8, suction plate 9, suction nozzle 10, air pump 11, tee pipe 12 and suction pipe 13, when the stand-up packaging bag is transferred between the two suction plates 9, the cylinder 8 can be started to drive the suction plate 9 close to the stand-up packaging bag, and then the air pump 11 can be started to suck air from the suction plate 9, so that the two suction plates 9 respectively suck the two sides of the stand-up packaging bag, and then the cylinder 8 can be started to drive the two suction plates 9 to separate, thereby opening the bag mouth of the stand-up packaging bag and improving the bag opening efficiency.
