Description

Technical Field

[0001] The present invention relates to the technical field of packaging equipment, and in particular to bag-type packaging equipment. Background Art

[0002] The packaging bags are generally made of plastic and sealed by hot pressing technology. Plastic bag sealing machines are divided into film continuous sealing machines, plastic film sealing machines, plastic hose tail sealing machines, pedal plastic sealing machines, etc. Most of these sealing machines generally require manual intervention for operation. When sealing some food packaging bags that require vacuum packaging, the air inside the packaging bags needs to be extracted. However, when the existing packaging machines are used, the packaging bags are placed with the opening facing upward, which makes the food inside the packaging bags all piled up at the bottom of the packaging bags instead of being evenly distributed. This makes the packaging bags after vacuum packaging uneven, with large bumps on the surface. Even in the process of transporting and stacking the packaging bags, some sharp protrusions rub against each other, which will damage the surface of the packaging bags.

Then the flip slide drives the sealing clamp base to move toward the heat sealing mechanism. During the movement, the bag first moves to the discharge conveyor belt. At this time, the vibration tray can vibrate the bag to cause the food inside the bag to spread out. Then the vacuum pipe performs vacuum treatment on the bag. Finally, when the bag moves to the heat sealing mechanism, it can be heat-sealed. The heat-sealed bag can be transported by the discharge conveyor belt. BRIEF DESCRIPTION OF THE DRAWINGS

Two sealing clamping plates 8 that are symmetrical front and back and can move and close toward the middle are installed at the bottom of the sealing clamping plate base 7, and an exhaust pipe 101 is located between the two sealing clamping plates 8. When the packaging bag moves to the top of the transfer tray 4, the two sealing clamping plates 8 and the exhaust pipe 101 move downward, so that the exhaust pipe 101 is inserted into the inner side of the packaging bag opening, and the two sealing clamping plates 8 move to the front and back sides of the packaging bag opening, and then the two sealing clamping plates 8 can be closed toward the middle to clamp and seal the packaging bag opening, and the exhaust pipe 101 is also clamped between the two sealing clamping plates 8, but the exhaust pipe 101 will not be closed, and the exhaust pipe 101 The packaging bag can be vacuum treated. A sealing drive mechanism 9 is installed on the sealing clamp base 7, which can make the two sealing clamps 8 close toward the middle. A sealing baffle mechanism 10 is installed under the two sealing clamps 8. When the two sealing clamps 8 close toward the middle to clamp and close the packaging bag mouth, the sealing baffle mechanism 10 can be driven to close toward the middle at the same time, so that the food inside the food packaging bag is blocked by the two sealing baffles 37 to prevent the food inside from moving to the packaging bag mouth after the food packaging bag is tilted 90°, affecting the heat-sealed packaging effect.

The two flip pull ropes 48 enter the inside of the flip slide rail 6 from the two flip rope holes 46 respectively and are fixedly connected to the two ends of the flip sliders 44. A flip motor 49 connected to the flip rope shaft 45 is fixedly installed on the outside of the flip slide rail 6. The flip motor 49 is connected to a power supply and a controller. When the two sealing clamps 8 clamp the packaging bag and move onto the discharge conveyor belt 12, the flipping motor 49 starts to drive the flipping rope shaft 45 to rotate, and the flipping rope shaft 45 wraps around one of the flipping ropes and releases the other, so that the flipping slider 44 can move in an arc direction within the flipping slide rail 6, so that the flipping slider 44 drives the sealing clamp base 7 to flip 90°. When the flipping slider 44 moves to the bottom end of the flipping slide rail 6, the sealing clamp base 7 drives the sealing clamp 8 to flip 90°, so that the packaging bag can be tilted 90°, and the food inside it can be quickly flattened under the vibration of the vibration tray 13, and then the vacuum pipe 101 can vacuum the packaging bag. The surface of the packaging bag after vacuumization is relatively flat, and there will be no food accumulation, protrusions or depressions.

[0040] Embodiment 9, based on embodiment 1, as shown in the attached Figure 4 , Figure 8 , Fig.10 , Fig.11 As shown, the heat sealing mechanism 14 includes a heat sealing chute 50, a heat sealing slider 51, a heat sealing slide bar 52, a heat sealing plate 53, a heat sealing tension spring 54, a heat sealing rope shaft 55, a heat sealing pull rope 56, and a heat sealing motor 57; Two heat-sealing chutes 50 are penetrated through the left end of the back plate 3 from front to back, and a heat-sealing slider 51 is slidably installed in each of the heat-sealing chutes 50, and a heat-sealing slide bar 52 is penetrated and slidably installed in the middle of each of the heat-sealing slide bars 51 from front to back, and a heat-sealing plate 53 is fixedly installed at the front end of the two heat-sealing slide bars 52, and a heat-sealing tension spring 54 is fixedly connected between the side faces of the two heat-sealing slide bars 51 that are away from each other and the corresponding heat-sealing chutes 50, and a heat-sealing rope shaft 55 located between the two heat-sealing chutes 50 is rotatably installed on the front side face of the back plate 3, and two heat-sealing pull ropes 56 that are respectively fixedly connected to the two heat-sealing sliders 51 are wound around the outer side face of the heat-sealing rope shaft 55, and a heat-sealing motor 57 connected to the heat-sealing rope shaft 55 is fixedly installed on the rear side face of the back plate 3, and the heat-sealing motor 57 is connected to a power supply and a controller; When the packaging bag continues to move to the left on the discharge conveyor 12, the two heat-sealing plates 53 can enter the position between the sealing clamping plate 8 and the sealing baffle 37, and then the heat-sealing motor 57 can be started to drive the heat-sealing rope shaft 55 to rotate to wrap the two heat-sealing pull ropes 56, so that the two heat-sealing pull ropes 56 pull the two heat-sealing sliders 51 to close toward the middle (when the heat-sealing slider 51 slides, the heat-sealing tension spring 54 is stretched to store force), so that the two heat-sealing plates 53 are closed to heat-seal the packaging bag. After heat-sealing, the heat-sealing motor 57 drives the heat-sealing rope shaft 55 to reverse and release the two heat-sealing pull ropes 56, so that the two heat-sealing sliders 51 are reset under the elastic force of their respective heat-sealing tension springs 54, and the two sealing clamping plates 8 are opened to both sides, so that the heat-sealed packaging bag is conveyed by the discharge conveyor 12; when it is necessary to adjust the position of the two heat-sealing plates 53 in the front-to-back direction, the two heat-sealing slide bars 52 can be moved back and forth at the same time to make the adjustment.

When the two heat sealing sliders 51 drive the two heat sealing slide rods 52 to close toward the middle, the rear ends of the two heat sealing slide rods 52 can slide in the heat sealing slide rail 60. When it is necessary to adjust the position of the two heat sealing plates 53 in the front-to-back direction, the heat sealing adjustment motor 58 can be started to drive the heat sealing adjustment screw rod 59 to rotate, and the heat sealing adjustment screw rod 59 can drive the heat sealing slide rail 60 to move forward and backward, thereby driving the two heat sealing slide rods 52 to move forward and backward, thereby realizing the adjustment of the two heat sealing plates 53 in the front-to-back direction.
