Description

Technical Field

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

[0002] After the lifting belt is produced, the lifting belt is wound and bundled to prevent scattering. After bundling, it is conveyed to a plastic sealing machine through a conveyor. The plastic sealing machine opens the opening of the packaging bag towards the conveying direction of the lifting belt, and cooperates with the conveying of the conveyor to convey the lifting belt into the packaging bag. Then, the packaging bag is sealed by a heat-sealing method. It is found in actual production that during the process of horizontally sealing the packaging bag by the plastic sealing machine, the situation that the lifting belt cannot completely enter the packaging bag may occur. The main reason is that after the lifting belt enters the packaging bag, friction will occur between the lifting belt and the packaging bag, resulting in the part of the lifting belt located on the conveyor slipping on the surface of the conveyor and unable to be completely input into the packaging bag. As a result, when heat-sealing, it will act on the lifting belt, causing defective products and increasing the cost. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide an automatic packaging and plastic sealing machine, which uses the gravity of the lifting belt to automatically fall into the packaging bag, so that the lifting belt can completely fall into the packaging bag without affecting its sealing.

[0004] The purpose of the utility model is achieved by the following technical solutions: an automatic packaging and plastic sealing machine, including a belt conveyor and a vertical plastic sealing mechanism. The vertical plastic sealing mechanism is arranged at the conveying end of the belt conveyor. The vertical plastic sealing mechanism includes a left bag clamping plate and a right bag clamping plate. The left bag clamping plate and the right bag clamping plate are arranged at intervals along the conveying direction of the belt conveyor. The left bag clamping plate has the freedom to move closer to or away from the right bag clamping plate. A plurality of negative pressure holes are opened on the end face of the left bag clamping plate close to the right bag clamping plate and on the end face of the right bag clamping plate close to the left bag clamping plate.

Specific embodiments

[0019] As Figures 1 to 3 shown, an automatic packaging and plastic-sealing machine includes a belt conveyor 1 and a vertical plastic-sealing mechanism. The vertical plastic-sealing mechanism is arranged at the conveying end of the belt conveyor 1. The vertical plastic-sealing mechanism includes a left bag clamping plate 2 and a right bag clamping plate 3. The left bag clamping plate 2 and the right bag clamping plate 3 are arranged at intervals along the conveying direction of the belt conveyor 1. The left bag clamping plate 2 has the freedom to move closer to or away from the right bag clamping plate 3. A plurality of negative pressure holes 4 are provided on the end face of the left bag clamping plate 2 close to the right bag clamping plate 3 and on the end face of the right bag clamping plate 3 close to the left bag clamping plate 2. The packaging bag is clamped between the left bag clamping plate 2 and the right bag clamping plate 3, and the opening of the packaging bag is opened upward. Heat-sealing pieces 21 are embedded on the end face of the left bag clamping plate 2 close to the right bag clamping plate 3 and on the end face of the right bag clamping plate 3 close to the left bag clamping plate 2. Two groups of limiting plates 19 are arranged at intervals along the width direction of the belt conveyor 1. A hoisting belt conveying space is formed between the two groups of limiting plates 19. A pushing cylinder 20 is horizontally installed on the conveying frame of the belt conveyor 1. The output shaft of the pushing cylinder 20 is connected to the limiting plate 19. The pushing cylinder 20 expands and contracts to adjust the distance between the two limiting plates 19, so that the distance between the two groups of limiting plates 19 is adapted to the width of the hoisting belt after bundling. Workers directly place the bundled hoisting belt between the two groups of limiting plates 19, and cooperate with the belt conveyor 1 to realize the positioning and conveying of the hoisting belt, so that the hoisting belt can accurately fall into the packaging bag. The packaging bag with the opening facing upward is clamped between the left bag clamping plate 2 and the right bag clamping plate 3. Both the left bag clamping plate 2 and the right bag clamping plate 3 are connected to a negative pressure pump through an air pipe, and negative pressure is generated through the negative pressure holes 4 to adsorb on both sides of the packaging bag. Then the left bag clamping plate 2 moves away from the right bag clamping plate 3 to open the opening of the packaging bag. The belt conveyor conveys the bundled hoisting belt to directly above the packaging bag. Under the guidance of the limiting plate 19, one end of the hoisting belt that breaks away from the belt conveyor 1 first deflects downward due to gravity and falls into the packaging bag. Finally, the hoisting belt completely falls into the packaging bag due to its own gravity. Finally, the opening of the packaging bag is heat-sealed by the heat-sealing piece 21, avoiding the hoisting belt blocking the opening of the packaging bag and affecting its sealing, and improving the packaging and plastic-sealing effect of the hoisting belt; the heat-sealing piece 21 is an electric heating plate, and the heat-sealing is a prior art and will not be elaborated.

[0020] Further, as shown in Figure 1 and Figure 2 shown, the vertical plastic sealing mechanism further includes a lifting cross beam 5, a horizontal sliding seat 6 and two support columns 7. The two support columns 7 are respectively arranged on both sides of the belt conveyor 1. The support columns 7 have the freedom to move closer to or away from the right clamping plate 3, that is, the support columns 7 are slidably installed on the bottom plate 22. A horizontal cylinder 23 is provided on the bottom plate 22. The telescopic shaft of the horizontal cylinder 23 is connected to the support column 7. By driving the two support columns 7 to move through the horizontal cylinder 23, the left clamping plate 2 is driven to move closer to or away from the right clamping plate 3 to open the opening of the packaging bag. The lifting cross beam 5 is located between the two support columns 7 and moves along the height direction of the support columns 7. A horizontal sliding seat 6 is provided on the end face of the lifting cross beam 5 close to the belt conveyor 1, and the horizontal sliding seat 6 moves along the direction perpendicular to the conveying direction of the belt conveyor 1. The left clamping plate 2 is fixed on the horizontal sliding seat 6. A vertical chute 8 is opened on the side of the support column 7 close to the lifting cross beam 5. A lead screw 9 is rotatably arranged in the vertical chute 8. A slider 10 is threadedly sleeved on the lead screw 9, and the slider 10 is slidably adapted to the vertical chute 8. Both ends of the lifting cross beam 5 are respectively arranged on the two sliders 10. A motor 11 is provided on the top of the support column 7. The output shaft of the motor 11 is drivingly connected to the lead screw 9. Rotating shafts 12 are fixed at both ends of the lifting cross beam 5, and the rotating shafts 12 are rotatably connected to the sliders 10. A packaging bag storage box 13 is provided on one side of the belt conveyor 1, and the packaging bag storage box 13 is located on the moving path of the left clamping plate 2. A linear driving module 17 is horizontally arranged on the end face of the lifting cross beam 5 close to the belt conveyor 1, and the horizontal sliding seat 6 is installed on the sliding seat of the linear driving module 17. The packaging bags are stored in the packaging bag storage box 13. By driving the horizontal sliding seat 6 to perform a linear motion in the horizontal direction through the linear driving module 17, the left clamping plate 2 is switched between the packaging bag storage box 13 and the right clamping plate 3. The left clamping plate 2 first moves to directly above the packaging bag storage box 13. Then, the motor 11 drives the lead screw 9 to rotate, so that the slider 10 moves up and down along the axial direction of the lead screw 9, thereby driving the left clamping plate 2 to move closer to the packaging bag storage box 13. While moving, the lifting cross beam 5 deflects downward by 90°, so that the negative pressure holes 4 of the left clamping plate 2 are directly opposite to the packaging bags in the packaging bag storage box 13. The slider 10 drives the left clamping plate 2 to contact the packaging bag, and adsorbs a packaging bag by means of negative pressure. Then, in cooperation with the lifting of the slider 10, the deflection of the lifting cross beam 5 and the movement of the horizontal sliding seat 6, the left clamping plate 2 is reset, that is, the left clamping plate 2 faces the right clamping plate 3. Then, the support column 7 drives the left clamping plate 2 to move closer to the right clamping plate 3, so that the right clamping plate 3 adsorbs the other side of the packaging bag by means of negative pressure. Finally, the left clamping plate 2 moves away from the right clamping plate 3 and resets, thereby opening the opening of the packaging bag, enabling the lifting belt to fall into the packaging bag. Then, the above process is repeated to complete the automatic plastic sealing of the lifting belt.

[0021] Further, as shown inFigure 1 and Figure 3 As shown in Figure 3 , a driving motor 14 is installed on the top of the slider 10. A driving cavity is arranged inside the slider 10. One end of the rotating shaft 12 far from the lifting cross beam 5 extends into the driving cavity and is fixed with a first bevel gear 15. The output shaft of the driving motor 14 extends into the driving cavity and is fixed with a second bevel gear 16. The second bevel gear 16 meshes with the first bevel gear 15. The driving motor 14 drives the rotating shaft 12 to rotate through the meshing of the second bevel gear 16 and the first bevel gear 15. The rotating shaft 12 drives the lifting cross beam 5 to deflect, completing the deflection of the packaging bag, so that the packaging bag changes from the horizontal storage state to the vertical opening state.

[0022] Furthermore, as Figure 1 shown in Figure 1 , a belt conveyor 18 is arranged below the right clamping plate 3. After the packaging bag is completed with plastic sealing, the left clamping plate 2 and the right clamping plate 3 are disconnected from the negative pressure, so that the packaging bag automatically falls on the belt conveyor 18 under its own gravity. The completed lifting belt is conveyed to the next workstation for boxing through the belt conveyor 18.
