A baffle 34 is fixedly installed on the side of the outside away from the driving component, a card plate 33 cooperating with the baffle 34 is fixedly installed on the top of the top plate 8, a clamping component for clamping the packaging bag is provided on the top of the placement box 9, a fixing rod 10 is symmetrically fixedly installed on the top of the placement box 9, an arc-shaped shell 11 is fixedly installed on the top of the fixing rod 10, a sliding mouth is provided in the middle of the arc-shaped shell 11, and a plurality of suction holes are provided on the upper and lower parts of the inner side of the arc-shaped shell 11, a slide plate 12 is slidably installed in the middle of the sliding mouth, an elastic rope 13 is fixedly connected to the inner end of the slide plate 12, and the two ends of the elastic rope 13 are respectively fixedly connected to the two ends of the arc-shaped shell 11, a pulling component for driving it to move outward is provided on the outer end of the slide plate 12, a vacuum pump 14 is fixedly connected to the top of the placement box 9, and the vacuum end of the vacuum pump 14 is connected to the vacuum end of the vacuum pump 14. The suction pipe 15 is connected with the inside of the arc-shaped shell 11. When in use, the hard packaging bag to be sealed is placed on the placement box 9, the packaging bag is clamped by the clamping assembly, and the vacuum pump 14 is started at the same time to extract the air in the arc-shaped shell 11 through the suction pipe 15, so that the two sides of the packaging bag are adsorbed through the suction holes, so that the two sides of the packaging bag are attached to the inner walls of the arc-shaped shell 11 on both sides. When the two sides of the packaging bag are adsorbed, the elastic rope 13 will be driven to move accordingly, so that the elastic rope 13 that is not completely tightened will be deformed, and finally the two sides of the packaging bag are adsorbed on the inner wall of the arc-shaped shell 11, and there is a gap between the suction hole and the packaging bag, so that the packaging bag can be adsorbed without blocking the suction hole. At this time, the elastic rope 13 is deformed and attached to the outside of the packaging bag. When the elastic rope 13 is deformed, it will drive the slide plate 12 to move accordingly. The first motor 4 is started to make its output shaft rotate intermittently to drive the connected rotating rod 3 to rotate, thereby driving the sprocket and the chain belt 5 to rotate, and then driving the carrier plate 6 to move accordingly. The carrier plate 6 drives the top plate 8 and the rotating shaft to move accordingly through the mounting column 7, so as to drive the placement box 9 to move accordingly. When the placement box 9 moves, it cooperates with the driving component to rotate forward. The forward rotation of the placement box 9 drives the rotating shaft to rotate and pull the torsion spring 32 to deform it and generate a force. As the placement box 9 rotates forward, it will cooperate with the pulling component to pull the slide plate 12 outward, so that the elastic rope 13 is pulled to make it move away from the surface of the packaging bag. When the pulling component cancels the pulling of the slide plate 12, the elastic rope 13 is reset and drives the slide plate 12 to move accordingly.As the placing plate 9 continues to move, it can continuously cooperate with the pulling component to pull and cancel the sliding plate 12, so that the elastic rope 13 can be continuously pulled and reset, and then the two sides of the packaging bag can be continuously slapped to vibrate, so as to shake off the particles attached to the inner side of the packaging bag and make them leave the inner side of the packaging bag, so that the packaging bag can be better filled with food, and the situation of food not being properly loaded or food leaking will not occur. At the same time, it avoids the situation that the presence of particles in the subsequent heat sealing of the packaging bag affects the sealing effect. The box 9 moves with the chain belt 5, so that the driving component will cancel the driving of the placement box 9. At this time, the torsion spring 32 releases the force to drive the rotating shaft and the placement box 9 to reverse and reset. The baffle 34 and the clamping plate 33 can limit the placement box 9, so that it can stop after resetting. As the placement box 9 continues to move with the chain belt 5, it will continue to cooperate with the driving component to drive it to rotate forward and reset, so that the pulling component can continuously drive the slide plate 12 to reciprocate, and then the elastic rope 13 can continuously beat the surface of the packaging bag to achieve the shaking off of the particles attached to its inner wall.

[0029] like Figure 3-4 As shown, the pulling assembly includes an L-shaped rod 16 rotatably mounted on the outer end of the slide plate 12, a limit plate 17 is fixedly mounted on the outer side of the L-shaped rod 16, a stop plate 18 is fixedly mounted on the outer end of the slide plate 12 and cooperates with the limit plate 17, the stop plate 18 is located above the limit plate 17, the top of the clamping plate 33 is fixedly connected to a semi-annular plate 20 through a straight rod 19, and extrusion blocks 21 cooperating with the L-shaped rod 16 are equidistantly arranged on the top of the semi-annular plate 20, the placement box 9 rotates forwardly through the fixed rod 10 to drive the arc shell 11 to rotate accordingly, thereby driving the slide plate 12 to move accordingly, the slide plate 12 drives the L-shaped rod 16 to move accordingly, the L-shaped rod 16 moves until it conflicts with the extrusion block 21, due to the existence of the limit plate 17 and the stop plate 18, the L-shaped rod 16 cannot be reversed, so that it remains in its original state, and as the L-shaped rod 16 moves, it will be affected by the extrusion block 21 The elastic cord 13 is pressed and moves outward, thereby driving the slide plate 12 to move outward and pulling the elastic cord 13. When the L-shaped rod 16 moves to separate from the squeezing block 21, the elastic cord 13 is reset and drives the slide plate 12 to reset, so that the elastic cord 13 hits the outside of the packaging bag. With the continuous movement of the L-shaped rod 16, it is continuously separated from the squeezing block 21, so that the slide plate 12 is continuously driven to move outward, and the elastic cord 13 is cooperated with to drive the slide plate 12 to reset, and then the elastic cord 13 can continuously hit the outside of the packaging bag through the reciprocating motion, so that the food particles at the seal on the inside of the packaging bag are shaken off. When the placement box 9 is rotated and reset, the L-shaped rod 16 rotates accordingly. After the L-shaped rod 16 conflicts with the squeezing block 21, the L-shaped rod 16 will rotate forward by itself, so that it is misaligned with the squeezing block 21, ensuring that it can be normally reset with the slide plate 12.

[0030] like Figure 3As shown, the extrusion block 21 is specifically configured as a block-shaped component with an arc surface on one side close to the L-shaped rod 16. The extrusion block 21 is fixedly connected to the top of the semi-ring plate 20, so that the L-shaped rod 16 can resist the extrusion block 21 and be squeezed by its arc surface to move outward when the placement box 9 rotates forward.

[0031] like Figure 3-5 As shown, a cylinder 22 is fixedly installed at the bottom of the top plate 8, and a filtering assembly for filtering particulate matter in food discharged from the cylinder 22 is provided on one side of the cylinder 22, and an air intake pipe 25 connected thereto is provided on the other side of the cylinder 22. A movable frame 27 is fixedly installed on the outer side of the placement box 9, and a movable shaft is rotatably installed on the upper part of the movable frame 27, and an L-shaped tube 28 is fixedly installed on the outer side of the movable shaft. One end of the air intake pipe 25 away from the cylinder 22 is connected to the L-shaped tube 28, and a one-way valve is provided in the L-shaped tube 28 and the filtering assembly. A second motor 29 is fixedly installed on the outer side of the movable frame 27, and the output shaft of the second motor 29 extends into the movable frame 27 and is fixedly connected to one end of the movable shaft. A piston 26 is provided inside the cylinder 22, and a pressing assembly is provided on the outer side of the piston 26 for cooperating with the rotating shaft to drive the piston 26 to reciprocate. When the packaging bag is placed on the placement box 9, the second motor 29 is started at this time to rotate its output shaft to drive the movable shaft and the L-shaped tube 28 to rotate so that the end of the L-shaped tube 28 away from the movable shaft When the bag is emptied, the piston 26 is driven by the pressing assembly to move in the direction close to the rotating shaft, so that air is sucked into the cylinder 22. At this time, the one-way valve in the filter assembly is closed, and the one-way valve in the L-shaped tube 28 is opened. The elastic rope 13 beats the surface of the bag to shake off the particles. At the same time, the floating particles generated will be sucked into the cylinder 22 through the L-shaped tube 28 and the air inlet pipe 25, so that the floating particles can be collected to prevent these particles from falling back into the bag, thereby preventing the particles from adhering to the inner wall of the bag again, thereby improving the cleaning effect. When the box 9 is rotated and reset, the rotating shaft is rotated and reset at this time. At the same time, the pressing assembly drives the piston 26 to reset, so that the air in the cylinder 22 is squeezed outward. At this time, the one-way valve in the filter assembly is opened, and the one-way valve in the L-shaped tube 28 is closed. The air passes through the filter assembly with the collected particles, so that the particles remain in the filter assembly.

[0032] like Figure 5As shown, the pressing assembly includes a pressing rod 30 fixedly connected to the side of the piston 26 close to the rotating shaft, and one end of the pressing rod 30 close to the rotating shaft extends outside the cylinder body 22. A cam 31 is fixedly installed at the bottom of the rotating shaft. The cam 31 always contacts one end of the pressing rod 30. A spring is provided on the side of the piston 26 away from the pressing rod 30. The forward rotation of the placement box 9 drives the rotating shaft to rotate accordingly, thereby driving the cam 31 to rotate accordingly. As the cam 31 rotates, the spring in the compressed state continuously releases its force to drive the piston 26 to move in the direction close to the rotating shaft. When the placement box 9 rotates to reset, the rotating shaft and the cam 31 are reset, so that the pressing rod 30 is continuously squeezed to drive the piston 26 to reset, and at the same time, the spring is compressed to deform it to generate a force.

[0033] like Figure 3 As shown, the filter assembly includes an exhaust pipe 23, which is fixedly connected to one side of the cylinder body 22, a one-way valve is arranged in the exhaust pipe 23, and one end of the exhaust pipe 23 away from the cylinder body 22 is tied and connected with a filter bag 24. When the piston 26 is reset, the air in the cylinder body 22 is squeezed outward. At this time, the one-way valve in the exhaust pipe 23 is opened, and the one-way valve in the L-shaped tube 28 is closed. The air enters the filter bag 24 through the exhaust pipe 23 with particulate matter, so that the particulate matter remains in the filter bag 24 and the air is discharged to achieve filtering of the particulate matter.

[0034] like Figure 1 As shown, the driving assembly includes a toggle plate 35 fixedly connected to the outside of the placement box 9, and a bent plate 36 cooperating with the toggle plate 35 is equidistantly fixedly installed on the top of the mounting frame 1. The movement of the chain belt 5 drives the carrier plate 6, the mounting column 7, the top plate 8, the rotating shaft and the placement box 9 to move accordingly. The placement box 9 drives the toggle plate 35 to move until it contacts the bent plate 36. As the placement box 9 continues to move, the toggle plate 35 is contacted by the bent plate 36 and drives the placement box 9 to rotate forward, while driving the rotating shaft to rotate and pull the torsion spring 32 to deform it to generate a force. When the toggle plate 35 leaves the bent plate 36, the torsion spring 32 releases its force and drives the rotating shaft and the placement box 9 to rotate and reset.

[0035] like Figure 3 As shown, the clamping assembly includes a clamping plate 37, a movable groove is symmetrically opened on the top of the placement box 9, a movable block is slidably installed inside the movable groove, the clamping plate 37 is fixedly installed on the top of the movable block, and an electric push rod is fixedly connected to the inner wall of the movable groove. The end of the electric push rod close to the movable block is fixedly connected to the movable block. The electric push rod can be started to extend it to drive the movable block to move, thereby driving the clamping plate 37 to move so as to clamp the outside of the packaging bag. Conversely, the electric push rod can be started to shorten it to cancel the clamping of the packaging bag by the clamping plate 37.

[0036] The present invention also provides a packaging machine using the above-mentioned conveying mechanism, including a packaging machine body 2, the packaging machine body 2 is a heat sealing machine, and the mounting frame 1 is fixedly installed on the top of the packaging machine body 2. When the packaging bag after cleaning the particles attached to the inner wall moves to the sealing part of the packaging machine body 2, the packaging machine body 2 can be started to heat seal the processed packaging bag.

[0037] Working principle: when in use, place the hard packaging bag to be sealed on the placement box 9, clamp the packaging bag through the clamping assembly, and start the vacuum pump 14 at the same time, so that the air in the arc shell 11 is extracted through the suction pipe 15, so that the two sides of the packaging bag are adsorbed through the suction holes, so that the two sides of the packaging bag are attached to the inner walls of the arc shell 11 on both sides. When the two sides of the packaging bag are adsorbed, the elastic rope 13 will be driven to move accordingly, so that the elastic rope 13 that is not completely tightened will be deformed, and finally the two sides of the packaging bag are adsorbed on the inner wall of the arc shell 11, and there is a gap between the suction hole and the packaging bag, so that the packaging bag can be adsorbed without blocking the suction hole. At this time, the elastic rope 13 is deformed and attached to the outside of the packaging bag. When the elastic rope 13 is deformed, When the first motor 4 is started, the slide plate 12 will be driven to move accordingly, and the first motor 4 will be started so that its output shaft will rotate intermittently to drive the connected rotating rod 3 to rotate, thereby driving the sprocket and the chain belt 5 to rotate, and then driving the carrier plate 6 to move accordingly. The carrier plate 6 drives the top plate 8 and the rotating shaft to move accordingly through the mounting column 7, so that the placement box 9 is driven to move accordingly, and the placement box 9 drives the toggle plate 35 to move until it contacts the bent plate 36. As the placement box 9 continues to move, the toggle plate 35 is contacted by the bent plate 36 and drives the placement box 9 to rotate forward, and at the same time drives the rotating shaft to rotate and pull the torsion spring 32 to deform it to generate a force. As the placement box 9 rotates forward, the arc shell 11 is driven to rotate accordingly through the fixed rod 10, thereby driving the slide plate 12 to move accordingly, and the slide plate 12 drives the L-shaped rod 16 to move accordingly, and the L-shaped rod 16 moves The L-shaped rod 16 moves to contact with the squeezing block 21. Due to the existence of the limiting plate 17 and the resisting plate 18, the L-shaped rod 16 cannot be reversed, so it remains in its original state. With the movement of the L-shaped rod 16, it is squeezed outward by the squeezing block 21, thereby driving the slide plate 12 to move outward and pull the elastic cord 13. When the L-shaped rod 16 moves to separate from the squeezing block 21, the elastic cord 13 is reset to drive the slide plate 12 to reset, so that the elastic cord 13 hits the outside of the packaging bag. With the continuous movement of the L-shaped rod 16, it continuously contacts and separates from the squeezing block 21, so that the slide plate 12 is continuously driven to move outward, and the elastic cord 13 drives the slide plate 12 to reset, so that the reciprocating elastic cord 13 can continuously hit the outside of the packaging bag, so that the food particles at the sealing portion on the inner side of the packaging bag are shaken off. When the toggle plate 35 leaves the bent plate 36, the torsion spring 32 releases its force to drive the rotating shaft and the placement box 9 to rotate and reset. When the placement box 9 rotates and resets, the L-shaped rod 16 rotates accordingly. After the L-shaped rod 16 conflicts with the extrusion block 21, the L-shaped rod 16 will rotate forward by itself, so that it is misaligned with the extrusion block 21, ensuring that it can be normally reset with the slide plate 12. The placement box 9 can be restricted by the baffle 34 and the card plate 33, so that it can stop after resetting. As the placement box 9 continues to move with the chain belt 5, the elastic rope 13 can continuously beat the surface of the packaging bag to shake off the particles attached to the inner wall of the packaging bag, so that the particles leave the inner side of the packaging bag, so that the packaging bag can be better filled with food, and there will be no situation where the food is not properly loaded or the food leaks.At the same time, it avoids the situation that the presence of particles affects the sealing effect when the packaging bag is heat-sealed later. The forward rotation of the placement box 9 drives the shaft to rotate, thereby driving the cam 31 to rotate. As the cam 31 rotates, the compressed spring continuously releases its force to drive the piston 26 to move in the direction close to the shaft, so that air is pumped into the cylinder 22. At this time, the one-way valve in the exhaust pipe 23 is closed, and the one-way valve in the L-shaped tube 28 is opened. The elastic rope 13 beats the surface of the packaging bag to shake off the particles. At the same time, the floating particles generated will be sucked into the cylinder 22 through the L-shaped tube 28 and the air inlet pipe 25, so that the floating particles can be collected, and these particles can be prevented from falling back into the packaging bag, thereby preventing the particles from adhering to the inner wall of the packaging bag again, thereby improving the cleaning effect. When the placement box 9 rotates to reset, the shaft rotates to reset, thereby driving the cam 31 The reset causes the pressing rod 30 to be continuously squeezed to drive the piston 26 to reset and the spring to be compressed to deform and generate a force, so that the air in the cylinder 22 is squeezed outward. At this time, the one-way valve in the exhaust pipe 23 is opened, and the one-way valve in the L-shaped tube 28 is closed. The air carries the particles through the exhaust pipe 23 into the filter bag 24, so that the particles remain in the filter bag 24, and the air is discharged to achieve the filtration of the particles. Finally, the packaging bag moves to the sealing part of the packaging machine body 2, and the second motor 29 is started to rotate its output shaft to drive the movable shaft and the L-shaped tube 28 to reset and leave the top of the packaging bag. At the same time, the vacuum pump 14 is turned off to cancel the adsorption of the packaging bag. The packaging machine body 2 can be started to heat-seal the processed packaging bag. When the heat-sealed packaging bag moves to the tail of the chain belt 5, the clamping assembly on the packaging bag is canceled, so that the packaging bag can be removed to achieve heat-sealed packaging.
