Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] See attached Figure 1-11 A PETG masterbatch packaging device comprises a workbench 1, a motor is arranged inside the workbench 1, a rotatable rotating disk 2 is arranged on the workbench 1, an output end of the motor is connected to the bottom of the rotating disk 2, and can drive the rotating disk 2 to rotate along its axis, a plurality of bag clamping mechanisms are arranged circumferentially on the rotating disk 2, and are used to clamp the two sides of the packaging bag, and the packaging bag is made of polyethylene or PVC material, and an opening mechanism, a feeding mechanism and a sealing mechanism are arranged in sequence around the outer wall of one side of the rotating disk 2, and the rotating disk 2 rotates to drive the bag clamping mechanism to pass through the opening mechanism, the feeding mechanism and the sealing mechanism in sequence, so as to automatically complete the packaging of the PETG masterbatch particles;

[0047] Furthermore, a conveyor is provided on the workbench 1, and the height of the conveyor is lower than the bag clamping mechanism, so that the packaged bags can directly fall onto the conveyor for transportation.

[0048] The bag clamping mechanism includes a pair of clamping arms 31, and the ends of the clamping arms 31 are provided with fixed clamping jaws 32 and movable clamping jaws 33. The movable clamping jaws 33 are rotatably connected to the ends of the clamping arms 31 to realize the relative opening or closing of the two clamping jaws, thereby clamping or releasing the packaging bag.

[0049] The bag clamping mechanism also includes a first cylinder 341, the output end of the first cylinder 341 is connected to a push rod 342, both ends of the push rod 342 are hinged with rocker arms 343, the middle part of the rocker arm 343 is hinged with the clamping arm 31, and the end away from the push rod 342 is hinged with a connecting rod 344, and the end of the connecting rod 344 away from the rocker arm 343 is hinged with the movable clamping claw 33 to drive the movable clamping claw 33 to move relative to the fixed clamping claw 32. The push rod 342 is pushed by the first cylinder 341, so that the rocker arm 343 pulls the connecting rod 344, and further separates the movable clamping claw 33 from the fixed clamping claw 32. At this time, the two clamping claws are opened, which facilitates the movement of the packaging bag between the two clamping claws. When the packaging bag is located between the two clamping claws, the push rod 342 is pulled by the first cylinder 341 to move, so that the movable clamping claw 33 and the fixed clamping claw 32 are close to each other and clamp the two side wall positions of the packaging bag.

[0050] A conveyor belt 7 is provided on the workbench 1, and the conveyor belt 7 is used to convey packaging bags in a circular rotation. A material taking mechanism is provided between the conveyor belt 7 and the rotating disk 2, and is used to convey the packaging bags on the conveyor belt 7 to the bag clamping mechanism, so that the packaging bags can automatically enter the bag clamping mechanism.

[0051] The material taking mechanism comprises a base 81 fixed on the workbench 1, a swing rod 82 is rotatably connected to the base 81, one side of the swing rod 82 is connected to the output end of the fourth cylinder 83, one end of the swing rod 82 is connected to a clamping arm 84, the end of the clamping arm 84 is provided with a fixed clamping plate 85 and a movable clamping plate 86 which cooperate with each other, the movable clamping plate 86 is rotatably connected to the clamping arm 84, and a fifth cylinder 87 is provided on the clamping arm 84, the output end of the fifth cylinder 87 is connected to the movable clamping plate 86, so that the movable clamping plate 86 is connected to the fixed clamping plate 85 and ... The opening and clamping of the clamping plate 85, through the fourth cylinder 83 driving the swing rod 82 to move, can make the movable clamping plate 86 and the fixed clamping plate 85 move to the conveyor belt 7, and then through the extension and contraction of the fifth cylinder 87, the movable clamping plate 86 and the fixed clamping plate 85 can cooperate to clamp the bag mouth side of the packaging bag, and then through the reverse operation of the fourth cylinder 83, the movable clamping plate 86 and the fixed clamping plate 85 are moved to the bag clamping mechanism, and then the two side wall positions of the packaging bag are clamped by the bag clamping mechanism;

[0052] The opening mechanism includes a pair of adsorption devices that can move relative to or oppositely, and are used to adsorb the two sides of the packaging bag and pull the two sides of the packaging bag to open the packaging bag;

[0053] The adsorption device includes a suction cup 41 for adsorbing the side of the packaging bag. The suction cup 41 is arranged with its mouth facing the packaging bag, and a hollow rod 42 is arranged on the other side thereof. The hollow rod 42 is connected to the inside of the suction cup 41, and a venting groove 43 is opened on its side. A piston 44 is arranged on the side of the hollow rod 42 away from the suction cup 41. A vacuum cylinder 45 is slidably connected to the outer wall of the piston 44. The front end of the vacuum cylinder 45 surrounds the hollow rod 42 to form a sealing structure. The venting groove 43 is located in the cavity of the vacuum cylinder 45. The piston 44 moves in the vacuum cylinder 45 to evacuate the gas inside the hollow rod 42. When the bag clamping mechanism clamps the packaging bag between the two suction cups 41, the two suction cups 41 and the hollow rod 42 are first controlled to fit on the two sides of the packaging bag, and then the two suction cups 41 are controlled to move in opposite directions. During this process, the hollow rod 42 drives the piston 44 to move in the air pump 45. At this time, negative pressure is formed in the air pump 45, so that the air in the hollow rod 42 enters the air pump 45 through the venting groove 43, that is, negative pressure is formed at the suction cups 41. At this time, the two suction cups 41 will respectively adsorb the two sides of the packaging bag and drive them to move, so that the bag mouth of the packaging bag is opened;

[0054] Furthermore, the bag clamping mechanism also includes a second cylinder 351, and a cam push plate 352 is connected to the output end of the top of the second cylinder 351. Downward inclined surfaces are formed on both sides of the top of the cam push plate 352, and the inclined surfaces on both sides are respectively abutted against different clamping arms 31. A slider 353 is provided on the clamping arm 31, and a sliding track 354 for the slider 353 to slide is provided at the bottom of the rotating disk 2, and a pair of clamping arms 31 are connected by a spring 355. When the opening mechanism opens the packaging bag, the output end of the second cylinder 351 is controlled to move upward. Since downward inclined surfaces are formed on both sides of the top of the cam push plate 352, the two clamping arms 31 will move relatively under the drive of the spring 355. At this time, the two clamping arms 31 squeeze the two side walls of the packaging bag, so that the opening of the packaging bag is further enlarged, which is convenient for subsequent loading.

[0055] The feeding mechanism includes a hopper 51 that can move up and down. The hopper 51 moves up and down, and the bottom of the hopper 51 can enter the packaging bag through the opening of the packaging bag for filling to avoid material collapse and scattering. A solenoid valve is provided at the bottom of the inner cavity of the hopper 51 to control the feeding;

[0056] Connecting frames 52 are provided on both sides of the hopper 51, and third cylinders 53 are provided at the bottom of the connecting frames 52 on both sides. The movement of the third cylinder 53 is used to realize the movement of the connecting frames 52. The hopper 51 includes a movable bucket 511 and a fixed bucket 512. The top of the movable bucket 511 is slidably connected to the cylindrical inner cavity at the bottom of the fixed bucket 512. The connecting frames 52 on both sides are connected to the two side arms of the movable bucket 511. The solenoid valve is arranged in the inner cavity of the movable bucket 511. The lifting movement of the connecting frame 52 causes the movable bucket 511 to form a lifting movement in the fixed bucket 512. The top of the movable bucket 511 and the bottom of the fixed bucket 512 are cylindrical, and the outer wall of the top of the movable bucket 511 fits the inner wall of the bottom of the fixed bucket 512 to prevent the material from leaking out when the movable bucket 511 moves in the fixed bucket 512. The lifting movement of the connecting frame 52 only drives the movable bucket 511 to move, which can reduce the required power compared to the upward movement of the hopper 51 as a whole.

[0057] A vertically arranged first rack 541 is provided on the connecting frame 52 close to the opening mechanism, a first gear 542 is meshedly connected to one side of the first rack 541, a first groove cam plate 543 is provided to one side of the first gear 542, first positioning columns 544 are slidably connected to the grooves at both ends of the first groove cam plate 543, and first slide rails 545 that move in the horizontal direction are provided on one side of the two first positioning columns 544, and the ends of the two first slide rails 545 are respectively connected to different hollow rods 42, so that the first groove cam plate 543 During rotation, the two hollow rods 42 move toward or oppositely, and the connecting frame 52 moves up and down. At this time, the first rack 541 can also move up and down, further making the first gear 542 drive the first groove cam plate 543 to intermittently reciprocate. At this time, the two first positioning columns 544 drive the first slide rails 545 on both sides to intermittently reciprocate horizontally, further making the suction cup 41 and the hollow rod 42 in the opening mechanism to intermittently reciprocate horizontally. At this time, the packaging bag can be opened without external power, which greatly reduces the cost of the equipment.

[0058] The sealing mechanism includes a pair of heat pressing plates 6 that can move relative to or oppositely. The heat pressing plates 6 are equipped with a heating device to control their temperature in the direction of the packaging bag. The pair of heat pressing plates 6 move towards each other to achieve heat-pressing sealing of the packaging bag opening.

[0059] A vertically arranged second rack 551 is provided on the connecting frame 52 close to the sealing mechanism, and a second gear 552 is meshedly connected to one side of the second rack 551, and a second groove cam plate 553 is provided on one side of the second gear 552. Second positioning columns 554 are slidably connected in the grooves at both ends of the second groove cam plate 553, and one side of the two second positioning columns 554 is provided with a second slide rail 555 that moves in the horizontal direction. The ends of the two second slide rails 555 are respectively connected to different hot pressing plates 6. The connecting frame 52 is lifted and lowered, which further makes the second rack 551 lift and lower. At this time, the second gear 552 drives the second groove cam plate 553 to rotate intermittently, and further makes the second positioning columns 554 on both sides drive the second slide rail 555 to move intermittently and reciprocate horizontally. At this time, the hot pressing plate 6 can move toward or oppositely, and no external power is required when the packaging bag is hot-pressed and sealed, which further reduces the cost of the equipment.

[0061] S1, putting PETG masterbatch particles into the hopper 51;

[0062] S2, placing the packaging bags on the conveyor belt 7 at intervals, and the conveyor belt 7 performs a one-side conveying action every 30-60 seconds;

[0063] S3, controlling the action of the material taking mechanism, the material taking mechanism clamps the packaging bag on the conveyor belt 7 and conveys it to the bag clamping mechanism, and then controls the bag clamping mechanism to clamp the two sides of the packaging bag;

[0064] S4, control the rotating disk 2 to rotate intermittently, and the rotation interval is the same as the interval time of the conveying action of the conveyor belt 7. The rotating disk 2 rotates intermittently, so that the bag clamping mechanism clamping the packaging bag moves into the opening mechanism, and then a pair of adsorption devices in the opening mechanism perform negative pressure adsorption on the two sides of the packaging bag, so that the bag mouth of the packaging bag is opened. During the adsorption and opening process, the two clamping arms 31 move toward each other, so that the two side arms of the packaging bag are close to the middle, which is more convenient for opening the bag mouth of the packaging;

[0065] S5, the rotating disk 2 rotates intermittently again, so that the bag clamping mechanism clamping the packaging bag moves to the position of the feeding mechanism, at this time, the third cylinder 53 pushes the hopper 51 to move downward, the movable hopper 511 is inserted into the packaging bag through the bag opening, and then the solenoid valve is opened to allow the PETG masterbatch particles in the hopper 51 to flow into the packaging bag. After the loading is completed, the hopper 51 is controlled to move upward so that it will not hinder the movement of the bag clamping mechanism;

[0066] S6, the rotating disk 2 is intermittently rotated again, so that the bag clamping mechanism clamping the packaging bag moves to the sealing mechanism, and at this time, a pair of hot pressing plates 6 are controlled to move toward each other and close to the two sides of the packaging bag so that the bag opening is closed, and then hot pressing and sealing are performed to achieve hot pressing and sealing of the packaging bag opening;

[0067] S7, the rotating disk 2 rotates intermittently again, at which time the bag clamping mechanism releases the clamping of the packaging bag, and the packaging bag of the packaged PETG masterbatch particles falls onto the conveyor and is transported to the next processing link.
