[0023] In this embodiment, Figure 1 The front, back, left and right are the directions. Cylinder six 34 is an angle cylinder, also called a rotary clamping cylinder, which means that the piston rod can be rotated 90 degrees to the right (or left) while extending and retracting (the clamping position end can be selected unilaterally / bilaterally, left-handed and right-handed), and then the clamping arm clamps the workpiece using the clamping stroke. This is a cylinder of existing technology; one end of the clamping block 32 is in the shape of an arrow. When the packaging bag needs to be replaced, the two cylinder seven 35 output ends on the bracket one 33 are telescopically moved, pushing the cylinder six 34 to slide left and right on the bracket one 33, thereby realizing the left and right sliding of the clamping block 32; through the two cylinders on the bracket two 38 The telescopic movement of the output end of cylinder five 28 pushes the connecting plate 29 to move, thereby pushing the sliders 30 on both sides to slide left and right, and then the suction cup 31 slides left and right to adjust its position; the packaging bag is grabbed by the suction cup 31, and under the telescopic movement of cylinder two 6, the bracket two 38 moves backward, and the packaging bag adsorbed by the corresponding suction cup 31 is tightly attached to the front side of bracket one 33. At this time, the clamping block 32 changes from an arrow pointing upward to an arrow pointing inside the packaging bag under the rotation of the output end of cylinder six 34, and shrinks backward to clamp the packaging bag, thereby realizing automatic size adjustment, adapting to packaging bags of various sizes, and improving work efficiency.

[0024] Reference Figure 2-Figure 4The top of the bottom plate 9 is fixedly connected to two sliding rods 2 36. Through holes are provided on the left and right sides of the rear side of the bracket 1 33. The outer wall of the sliding rod 2 36 is slidably connected to the inner wall of the through hole of the bracket 1 33. The bottom of the cylinder 6 34 is slidably connected to the top of the bracket 1 33. The side projection of the bracket 1 33 is L-shaped, and the front side of the bracket 1 33 is an L-shaped raised side. The interior of the front side of the bracket 1 33 is a hollow structure.

The width of the block 32 is greater than the width of the hollow structure on the front side of the bracket 1 33.

[0025] Specifically, the lifting function of bracket 1 33 is realized by the sliding connection between slide bar 2 36 and bracket 1 33 and the contraction movement of cylinder 3 17. Through the hollow structure inside the front side of bracket 1 33 and driven by cylinder 7 35, cylinder 6 34 is driven to slide left and right, thereby driving the clamping block 32 to slide left and right to adapt to packaging bags of different sizes. The width of the clamping block 32 is greater than the width of the hollow structure on the front side of bracket 1 33. On the basis of realizing the left and right movement of the clamping block 32, it is ensured that the clamping block 32 can be clamped in the packaging bag between the clamping block 32 and the front side of bracket 1 33 when the cylinder 6 34 contracts backward. When the packaging bag is not received, the arrow of the clamping block 32 is upward. When the packaging bag is received, under the drive of cylinder 6 34, one end of the arrow of the clamping block 32 rotates to point to the packaging bag, and the cylinder 6 34 contracts backward to fix the packaging bag between the clamping block 32 and the front side of bracket 1 33.

[0026] Reference Figure 3 The side projection of the second bracket 38 is L-shaped, the rear side of the second bracket 38 is the raised side of the L-shape, the interior of the rear side of the second bracket 38 is a hollow structure, the sliders 30 are respectively located in the middle and left and right sides of the rear side of the second bracket 38, the middle slider 30 is fixedly connected to the interior of the rear side of the second bracket 38, the rear outer wall of the middle slider 30 is fixedly set at one end of the two suction cups 31, and the upper and lower sides of the middle of the two side sliders 30 are slidably connected to the inner wall of the hollow structure on the rear side of the second bracket 38, and the output ends of the two cylinders 5 28 are respectively directed towards the left and right sides of the second bracket 38.

[0027] Specifically, an air tube is provided inside the suction cup 31. When a packaging bag is received, the air tube draws air so that the suction cup 31 can suck the packaging bag. When the packaging bag needs to be replaced, the sliders 30 on the left and right sides of the bracket 2 38 pass through the hollow structure on the rear side of the bracket 2 38 and move to the designated position under the action of the connecting plate 29 and the cylinder 5 28, thereby realizing the adjustment of different packaging bag sizes.

[0028] Reference Figure 2-Figure 4A movable wire tube 18 is fixedly provided on the lower side of the support plate 2 15, and the lower side of the movable wire tube 18 is fixedly connected to the top of the bottom plate 9. There are two slides 12, and the rear sides of the two slides 12 are respectively fixedly connected to the upper and lower sides of the front side of the support plate 2 15. The front side of the support plate 2 15 is fixedly connected with a fixed block 13, and the fixed block 13 is fixedly connected to the support plate 2 15 between the two slides 12. The inside of the fixed block 13 is fixedly connected with a belt 14, and rollers 21 are fixedly provided at both ends of the belt 14. The rollers 21 are rotatably connected to the support plate 1 8. A motor 17 is fixedly provided on the top of the right support plate 18, and the output end of the motor 17 passes through the top of the right support plate 18 and is fixed on the top of the right roller 21. The bottom of the support plate 18 is fixedly connected to the top of the bottom plate 9.

[0029] Specifically, with the support of the support plate 8, the right roller 21 is driven to rotate through the rotation of the output end of the motor 7, thereby driving the belt 14 to rotate, and then driving the fixed block 13 fixed on the belt 14 to move. Under the sliding connection of the slide rod 11 and the slide cylinder 12, the support plate 2 15 can slide left and right, so that the bag grabbing machine 2 fixed on the support plate 2 15 can move left and right. Under the action of the moving wire tube 18, the bag grabbing machine 2 can also operate during the movement process.

[0030] Reference Figure 1 A motor 26 is fixedly connected to the right side of the support rod 25 on the left rear side of the top of the bottom plate 9, and a bag grabbing machine 2 27 is fixedly provided at the output end of the motor 26. The composition and structure of the bag grabbing machine 27 are the same as those of the bag grabbing machine 1 2. A bag storage plate 24 is provided on the right side of the support rod 25 on the left rear side of the top of the bottom plate 9. Cylinder four 23 is provided on both sides of the bag storage plate 24. The bottom of the cylinder four 23 is fixedly connected to the top of the bottom plate 9. A baffle 22 is provided on the front side of the bag storage plate 24, and the baffle 22 is provided on the top of the bottom plate 9.

[0031] Specifically, when the size of the packaging bag needs to be changed, the bag grabber 27 is adjusted to the appropriate size, and the motor 26 on the support rod 25 rotates the bag grabber 27 downward 90 degrees, and then the cylinder 26 inside the bag grabber 27 telescopic mechanism and the suction cup 31 grab and lift the packaging bag, and then the motor 26 rotates upward 90 degrees, and the bag grabber 27 and the cylinder 26 inside the bag grabber 1 move in the same direction, so that the suction cup 31 fits together, the suction cup 31 on the bag grabber 27 is deflated, and the suction cup 31 on the bag grabber 1 2 is evacuated, completing the transfer of the packaging bag.

[0032] Reference Figure 1 A controller 19 is provided on the top of the bottom plate 9, a sensor 20 is provided on the right front outer wall of the left side slide bar 2 36, and a sensor 1 16 is provided on the front side of the cylinder 3 17.

[0033] Specifically, sensor 1 16 and sensor 2 20 are both occlusion sensors with adjustable distances, which are existing technologies. When the bag grabber 2 27 fails to grab the packaging bag successfully, sensor 2 20 is not triggered, and sensor 2 20 transmits a signal to the controller 19, determining that the grabbing module has failed and performing manual maintenance. When filling, sensor 16 is triggered, which means that material has leaked and fallen, causing sensor 16 to be blocked. Sensor 16 transmits a signal to the controller 19, determining that the filling has failed and performing manual maintenance, thereby realizing automated troubleshooting feedback for sealed packaging.

[0034] Reference Figure 2 The four corners of the bottom of the bottom plate 9 are fixedly connected with supporting legs 10, and a discharge plate 37 is provided at the bottom of the bottom plate 9. A through hole is opened inside the bottom plate 9, and the front side of the bottom plate 9 with the through hole is fixedly connected to the front side of the discharge plate 37; the product after packaging and sealing can be delivered through the discharge plate 37.

[0035] Reference Figure 1-Figure 5 The upper end of the support rod 25 is fixedly connected to the top plate 1, and a through hole is opened inside the top plate 1. Two cylinders 3 are fixedly connected to the inside of the top plate 1. The two cylinders 3 are respectively arranged on the left and right sides of the through hole of the top plate 1. A hopper 4 is fixedly set in the middle of the two cylinders 3. A clamping plate 5 is set on the lower side of the front and back sides of the hopper 4. The bottom of the top plate 1 is fixedly connected to a sealing machine 39. The sealing machine 39 is set on the front and back sides of the bottom of the through hole of the top plate 1. One end of the clamping block 32 is arrow-shaped.

[0036] Specifically, after the clamping block 32 grabs the packaging bag, the cylinder 2 6 contracts, causing the suction cup 31 to pull the packaging bag backward, opening the packaging bag opening. The hopper 4 on the top plate 1 moves downward under the contraction of the cylinder 1 3, and the discharge port of the hopper 4 is opened to discharge the material under the interference of the clamping plate 5 and the top plate 1. After the discharge is completed, the hopper 4 moves upward under the action of the cylinder 1 3 to complete the filling. The extension and contraction movement of the cylinder 3 17 causes the bracket 1 33 to move upward, thereby driving the clamping block 32 to move upward, and the packaging bag stuck by the clamping block 32 also moves upward and moves to the inside of the sealing machine 39. Under the action of the sealing machine 39, the sealing is completed. The clamping block 32 loosens the packaging bag under the extension and rotation of the cylinder 6 34, and the packaging bag is sent out through the discharge plate 37. At this point, the filling and sealing of the product are completed.

[0037] Working principle: When the packaging bag needs to be replaced, the two cylinders 7 35 on the bracket 1 33 on the bag grabbing machine 1 and the bag grabbing machine 2 27 move by telescopic movement, pushing the cylinder 6 34 to slide to the specified position on the bracket 1 33, thereby moving the block 32 of the cylinder 6 34 to the specified position; through the telescopic movement of the output ends of the two cylinders 5 28 on the bracket 2 38, the connecting plate 29 is pushed to move, thereby pushing the slider 30 to the specified position, and then the suction cup 31 is moved to the specified position; when the device is running, the motor 26 on the bag grabbing machine 27 rotates downward, and then through the telescopic movement of the cylinder 2 6 inside the bag grabbing machine 27, the suction cup 31 is extended toward the bag storage plate 24, and the packaging on the bag storage plate 24 is The bag is grabbed, and then the motor 26 rotates upward, the bag grabbing machine 27 and the cylinder 26 inside the bag grabbing machine 2 move in the same direction, so that the suction cup 31 fits together, the suction cup 31 on the bag grabbing machine 27 is deflated, and the suction cup 31 on the bag grabbing machine 2 is exhausted, completing the transfer of the packaging bag; the motor 17 set on the support plate 18 starts to rotate, thereby driving the belt 14 to roll on the roller 21, and then driving the fixed block 13 to move left and right, so that the bag grabbing machine 2 after grabbing the packaging bag moves to the right under the sliding connection with the slide bar 11, and through the moving wire tube 18, it is realized that the bag grabbing machine 2 can also operate during the movement; when the bag grabbing machine 2 moves to the right to the front side of the bracket 13, the cylinder 26 extends and drives The second bracket 38 moves backward, so that the packaging bag on the suction cup 31 is attached to the front outer wall of the first bracket 33. At this time, the clamping block 32 is transformed from a right angle to the bracket 1 33 to a parallel state through the rotation and expansion of the sixth cylinder 34, and shrinks backward to clamp the packaging bag. The suction cup 31 is moved forward by the retraction movement of the second cylinder 6, and the packaging bag adsorbed by the suction cup 31 is opened; the retraction movement of the first cylinder 3 drives the hopper 4 to move downward through the top plate 1. Under the interference of the clamping plates 5 and the top plate 1 on the front and rear sides of the hopper 4, the discharge port of the hopper 4 is opened and filling begins; after a certain period of time, the hopper 4 is moved upward by the extension movement of the first cylinder 3, and the discharge port of the hopper 4 is closed, completing the filling; the suction cup 31 is released by the release movement of the second cylinder 6. The air is released to release the adsorption of the packaging bag, and the bracket 1 33 moves upward through the extension movement of the cylinder 3 17 and the sliding connection between the bracket 1 33 and the slide bar 2 36, thereby driving the packaging bag stuck by the block 32 to move upward; when the upper side of the packaging bag moves to the inside of the sealing machine 39 provided at the bottom of the top plate 1, the cylinder 3 17 stops the telescopic movement, and the packaging bag is sealed by the sealing machine 39. Then, the fixing of the packaging bag by the block 32 is released through the rotation and telescopic movement of the cylinder 6 34, and the packaging bag falls onto the discharge plate 37 on the bottom plate 9, completing the filling and sealing operation; the cylinder 3 17 drives the bracket 1 33 to retract to its original position, waiting for the next operation. At this point, the function of adapting to the filling and sealing of packaging bags of various sizes is realized.
