[0049] See appendix Figure 3 The movable arm 12 is connected to the first drive shaft 7, and the second drive shaft 8 and the third drive shaft 9 are both rotatably mounted on the movable arm 12.

[0050] See appendix Figure 4-57. The driven assembly 13 is rotatably mounted on the moving arm 12. The driven assembly 13 is located below the drive shaft assembly 6. The driven assembly 13 includes a first driven member 14 and a second driven member 15. Both the second drive shaft 8 and the third drive shaft 9 are connected to a drive gear 23. The drive gear 23 meshes with an intermediate gear 24. Both the first driven member 14 and the second driven member 15 have driven tooth segments 25, which mesh with the intermediate gear 24. The intermediate gear 24 has more teeth than the drive gear 23. The number of teeth, the intermediate gear 24 is coaxially arranged, the first driven member 14 is connected to the first clamping arm 16, the first clamping arm 16 is connected to the first clamping plate 17, the second driven member 15 is connected to the second clamping arm 18, the second clamping arm 18 is connected to the second clamping plate 19, the first clamping arm 16 and the second clamping arm 18 both have a clearance state and a bag clamping state, the first clamping arm 16 and the second clamping arm 18 swing in the same direction to switch between the clearance state and the bag clamping state, the first clamping plate 17 and the second clamping plate 19 cooperate to clamp the bag opening of the packaging bag.

[0051] In this embodiment, when clamping and placing the packaging bag, the first motor 21 and the second motor 22 drive the second drive shaft 8 and the third drive shaft 9 to rotate in opposite directions, and the first clamping plate 17 and the second clamping plate 19 swing in opposite directions; when feeding the bag, the rotating motor 20 drives the first drive shaft 7 to rotate and drive the moving arm 12 to swing, while the first motor 21 and the second motor 22 drive the second drive shaft 8 and the third drive shaft 9 to rotate in the same direction, and the first clamping plate 17 and the second clamping plate 19 swing in the same direction to avoid the clamping parts at the vacuum packaging machine; during the bag loading process, the intermediate gear 24 rotates around the drive gear 23, driving the driven gear segment 25 to rotate, and the first clamping plate 17 and the second clamping plate 19 swing in the same direction to drive the bag body to swing, offsetting the bag body offset caused by the swing of the moving arm 12.

[0052] Among them, the bag transfer robot 5 connects the cutting mechanism 4 and the packaging mechanism of the vacuum packaging machine. The packaging mechanism is a mature technology. The transmission form of the drive shaft group 6 and the power component 11 can be a drive arm, a driven arm and a connecting rod. The connecting rod is hinged to the drive arm and the driven arm respectively. The drive arm and the driven arm are connected to the drive shaft group 6 and the power component 11 respectively. It can also be in the form of a synchronous pulley and synchronous belt.

[0053] Bearings are installed between the shafts to reduce friction, and a support sleeve 66 is installed on the fixed seat 10 to support the first drive shaft 7; the first clamping plate 17 is detachably connected to the pad 67, and the pad 67 can be replaced to adapt to different bag thicknesses.

[0054] The first clamping arm 16 and the second clamping arm 18 are offset in the axial direction, so the first clamping plate 17 and the second clamping plate 19 are axially extended relative to the corresponding clamping arms, so that the two can be clamped together, and the clamping plates and clamping arms can be set as one piece.

[0055] The linear velocity of the driven component 13 and the linear velocity of the intermediate gear 24 rotating around the driving gear 23 are assumed to have uniform tooth backlash. The diameter of the driven tooth segment 25 is equal to the diameter of the driving gear 23. The same circumferential distance corresponds to the same angle. Therefore, the angle at which the driven component 13 drives the corresponding clamping plate to swing is equal to the angle at which the moving arm 12 drives the intermediate gear 24 to rotate around the driving gear 23. The driven component can be an incomplete gear with the clamping arm connected to the toothless part, or it can be a complete gear with the clamping arm connected to the side, or it can be a gear shaft with the driven components sleeved together and the clamping arm connected to the shaft.

[0056] The movable arm 12 is provided with a connecting plate 68 and a cover 69. The connecting plate 68 and the cover 69 form an inner cavity. The driving gear 23, the intermediate gear 24 and the driven gear segment 25 are disposed in the inner cavity, which is waterproof and dustproof. The movable arm 12 is provided with a through groove 70. One side of the groove wall of the through groove 70 is provided with a first mounting hole for the second driven member 15 to pass through, and the other side of the groove wall of the through groove 70 is provided with a second mounting hole for the first driven member 14 and the second driven member 15 to pass through, which supports both ends of the driven assembly 13.

[0058] See appendix Figure 8 The bag-making mechanism 2 includes an inclined folding plate 26. The folding plate 26 has a first edge and a second edge on its left and right sides, forming an angle. A connecting block 27 is hinged to the rear end of the folding plate 26. An adjusting screw 28 is connected to the connecting block 27.

A pull rod 32 is hinged to the front end of the folding plate 26. The other end of the pull rod 32 is hinged to the mounting plate 29. The rolled material gradually rises along the first edge and the second edge to achieve folding.

[0059] In this embodiment, when the height of the bag changes, rotating the adjusting screw 28 causes the folding plate 26 to rise or fall via the connecting block 27, and the pull rod 32 swings to adapt.

The adjusting nut is connected to the adjusting plate 30. The mounting frame 31 is equipped with a sensor to monitor the height of the continuous rolled material standing up on both sides. The controller controls the motor to drive the screw based on the height difference, which in turn moves the adjusting plate 30 left and right.

The lifting adjustment of the mounting seat is set below the folding plate 26, and the front and rear movement adjustment of the adjustment block is set on the mounting seat.

[0070] In this embodiment, the guide plate group 59 is installed on the strip, and the conveyor roller group 58 is respectively installed on the first vertical shaft 75 and the second vertical shaft 76. The first vertical shaft 75 is directly connected to the motor, and the first vertical shaft 75 and the second vertical shaft 76 are driven by gear meshing. The second vertical shaft 76 is connected to the rotating shaft through the swing arm. The rotating shaft is rotatably mounted on the flip plate, and the flip plate is oscillating. During installation, the flip plate oscillates into place, and then the handle drives the rotating shaft to rotate, which drives the second vertical shaft 76 to oscillate through the swing arm, thus completing the installation. The punching assembly 60 is used to punch out the rounded corners of the four corners of the bag body and to shape it.

[0071] See appendix Figure 15-16 The cutting mechanism 4 is adjustable to move back and forth relative to the bag-transferring robot 5. The cutting mechanism 4 includes a cutting component 61 and a guide plate 62. The cutting component 61 includes a cutter 63 and a bottom cutter 64. The cutter 63 is adjustable to move left and right relative to the bottom cutter 64. The guide plate 62 is disposed on the feeding side and the discharging side of the cutting component 61.
