[0017] Example 1 Please see Figure 1-10 An eye mask bagging device includes a frame 1, an eye mask conveying unit 2, a packaging bag conveying unit 3, a flaring unit 4, a lifting unit 5, and a pushing unit 6. The eye mask conveying unit 2, the lifting unit 5, and the flaring unit 4 are sequentially connected within the frame 1 along its length. The eye mask conveying unit 2 conveys the eye mask to the lifting unit 5. The pushing unit 6 and the packaging bag conveying unit 6 are sequentially connected to the frame 1 along the conveying direction of the conveying unit. The packaging bag conveying unit 3 is located above the flaring unit 4. The packaging bag conveying unit 3 conveys the packaging bag to the top of the flaring unit 4 and cooperates with the flaring unit 4 to open the opening of the packaging bag. The eye mask located on the lifting unit 5 is lifted to the front of the opening of the packaging bag by the lifting unit 5. The pushing unit 6 pushes the eye mask located in front of the opening of the packaging bag into the corresponding packaging bag.

[0018] In practical applications, the eye mask delivery unit 2 transports eye masks from one end of the frame 1 to the other. Specifically, the eye masks are injected into the mold via an external filling unit and formed into eye mask products by a molding unit. Then, the eye mask delivery unit 2 transports the eye masks to the other end of the frame 1, specifically above the lifting unit 5. The lifting unit 5 lifts the eye masks, preventing interference between the pushing unit 6 and other eye masks during the pushing process. This allows the eye masks to be pushed one by one into the packaging bag, and the packaging bag is then transported via a packaging bag delivery system. Unit 3 is conveyed above the flaring unit 4, and the flaring unit 4 opens the bag opening so that the bag opening corresponds to the eye mask lifted by the lifting unit 5. Under the pushing action of the pushing unit 6, the eye mask is pushed into the packaging bag, completing the packaging of the eye mask. The lifting unit 5 can prevent the pushing unit 6 from affecting other packaging bags that have not been lifted when pushing. The lifting unit 5 can also play a positioning role, so that the position of the eye mask and the bag opening corresponds, ensuring that the eye mask can be pushed into the packaging bag under the action of the pushing unit 6.

[0019] Preferably, the eye membrane delivery unit 2 includes a partition conveyor belt 21 and L-shaped baffles 22. There are multiple partition conveyor belts 21 arranged side by side. Each partition conveyor belt 21 has L-shaped baffles 22 symmetrically arranged on both sides. The length of the L-shaped baffles 22 extends along the conveying direction, and the ends of the L-shaped baffles 22 extend above the lifting unit 5. The horizontal part of the L-shaped baffles 22 is flush with the conveying surface of the partition conveyor belt 21. A single partition conveyor belt 21 and the horizontal part of the L-shaped baffles 22 on both sides are used to deliver a single eye membrane. There is a gap 23 between the horizontal parts of the symmetrically arranged L-shaped baffles 22 to allow the partitions of the partition conveyor belt 21 to move. The partitions can push the eye membrane above the lifting unit 5.

[0020] In the above design, the partition conveyor belt 21 is a partition conveyor belt 21 well known to those skilled in the art. The symmetrically arranged L-shaped baffles 22 can prevent the eye membrane from falling off the sides of the partition conveyor belt 21. The end of the L-shaped baffle 22 extends to the top of the support rod 52, so that when the eye membrane is conveyed to the end of the L-shaped baffle 22 by the partition conveyor belt 21, the support rod 52 can pass through the gap 23 to lift the eye membrane. Specifically, in this embodiment, the L-shaped baffle 22 continues to extend horizontally from the end of the partition conveyor belt 21 and extends to the top of the support rod 52. The eye membrane is located between two adjacent partitions of the partition conveyor belt 21. When the eye membrane is at the end of the conveyor belt 21, the partition behind the eye membrane will push the eye membrane to continue to move forward along the L-shaped baffle 22, and finally to the end of the L-shaped baffle 22, that is, the top of the support rod 52, thereby ensuring that the support rod 52 can lift the eye membrane to the position corresponding to the opening of the packaging bag.

[0021] Preferably, the lifting unit 5 includes multiple lifting modules, and the number of lifting modules corresponds one-to-one with the number of partition conveyor belts 21. Each lifting module includes a first drive cylinder 51, a support rod 52, and a support plate. The cylinder body of the first drive cylinder 51 is connected to the frame 1, and the power output end of the first drive cylinder 51 is connected to the support plate. Two support rods 52 are connected to each support plate. The length of the support rods 52 extends along the conveying direction. The support rods 52 are located below the L-shaped baffle 22 and match the gap 23. The support rods 52 can be driven to rise by the first drive cylinder 51 to pass through the gap 23 and lift the eye membrane located on the L-shaped baffle 22.

[0022] With the above design, the first drive cylinder 51 can drive the support rod 52 to move up and down along the height direction of the frame 1. In this embodiment, the support rod 52 and the support plate form a structure with a horizontal cross section of H shape. The support rod 52 serves as the two sides of the H shape, and a support part is formed between the two support rods 52, which can support the eye membrane and lift it up through the first drive cylinder 51. The support part formed by the support rod 52 can effectively support the eye membrane.

[0023] Preferably, the pushing unit 6 includes a connecting plate, a first lead screw module 61, a first optical axis module, and a push rod 62. The first lead screw module 61 and the first optical axis module are disposed on both sides of the frame 1 and arranged along the length direction of the frame 1. The two ends of the connecting plate are respectively connected to the first lead screw module 61 and the first optical axis module. The push rod 62 has an L-shaped structure, and the vertical parts of multiple push rods 62 are all connected to the connecting plate. The number of push rods 62 matches the number of partition conveyor belts. The first lead screw module 61 is used to drive the connecting plate to move along the length direction of the frame 1. The horizontal part of the push rod 62 can push the eye membrane located on the support rod 52 into the packaging bag.

[0024] In this embodiment, the first lead screw module 61 adopts a lead screw drive well known to those skilled in the art, such as a ball screw or a motor lead screw. The first optical axis module adopts an optical axis well known to those skilled in the art, which serves as a guide. The subsequent second lead screw module 71 and second optical axis module are also like this, and will not be described in detail here. The first lead screw module 61 can drive the push rod 62 to move. The push rod 62 can push the eye mask on the support rod 52 into the packaging bag. By driving the connecting plate to move through the movable end of the first lead screw module 61, the multiple push rods 62 corresponding to the eye mask move together with the connecting plate. Thus, multiple eye masks can be pushed into the corresponding packaging bags by the push rods 62. Specifically, in this embodiment, the push rod 62 is located above the partition conveyor belt 21. After the eye mask is lifted by the lifting unit 5, the push rod 62 can push the lifted eye mask into the packaging bag. The first lead screw module 61 can ensure the direction of movement of the push rod 62, thereby ensuring that the eye mask can be pushed into the packaging bag.

[0025] Preferably, the packaging bag conveying unit 3 includes a first motor 31, a shaft 32, a fixing plate 33, and a material rack 34 for placing packaging bags. The material rack 34 is connected to the frame 1 and located above the flaring unit 4. The first motor 31 is connected to the frame 1, and the output end of the first motor 31 is fixedly connected to the shaft 32 and used to drive the shaft 32 to rotate. The fixing plate 33 is fixedly connected to the shaft 32 and located below the material rack 34. The fixing plate 33 is provided with two second drive cylinders 331, which are located at the top of one end and the bottom of the other end of the fixing plate 33, respectively. The output end of the second drive cylinder 331 is provided with a first suction cup 332, which is driven to rise and fall by the second drive cylinder 331 to adsorb the packaging bags located on the material rack 34. The first motor 31 is used to drive the fixing plate 33 to swing so that the adsorbed packaging bags are horizontally arranged above the flaring unit 4.

[0026] Through the above design, the first motor 31 adopts a drive motor well known to those skilled in the art, such as a stepper motor, and the subsequent second and third motors 73 are also like this, which will not be elaborated here. The first motor 31 can drive the shaft 32 to rotate, and the shaft 32 drives the fixed plate 33 to rotate. In this embodiment, the entire device is a multi-station packaging device, so one shaft 32 can drive multiple fixed plates 33 to rotate, thereby realizing the feeding process of multiple packaging bags. Specifically, the first motor 31 drives the shaft 32 to rotate, and the shaft 32 drives multiple fixed plates 33 to rotate. The second drive cylinder on the fixed plate 33 331 can drive the first suction cup 332 to rise, thereby adsorbing the packaging bag in the material rack 34. The first motor 31 drives the fixing plate 33 to flip, so that the first suction cup 332 is directly above the flaring unit 4. Finally, the second drive cylinder 331 drives the first suction cup 332 to fall to complete the unloading process of the packaging bag. Since the second cylinder is symmetrical about the center of the fixing plate 33, when the second drive cylinder 331 on one side of the fixing plate 33 falls, the second drive cylinder 331 on the other side of the fixing plate 33 can drive the first suction cup 332 to adsorb the packaging bag, thereby improving the unloading efficiency.

[0027] Preferably, the flaring unit 4 includes a support platform 41 and a third driving cylinder 42. The support platform 41 is connected to the frame 1 and located below the fixing plate 33. The third driving cylinder 42 is connected to the support platform 41. A second suction cup 421 is provided on the output end of the third driving cylinder 42. The third driving cylinder 42 is used to drive the second suction cup 421 to rise and fall, so as to adsorb the other side of the packaging bag in the horizontal state and open the bag opening. When the fixing plate 33 swings to the horizontal state, the first suction cup 332 located above the second suction cup 421 corresponds vertically to the second suction cup 421.

[0028] In the above design, the third driving cylinder 42 can drive the second suction cup 421 to rise and fall. The first suction cup 332 is attached to one side of the packaging bag, and the second suction cup 421 is attached to the other side of the packaging bag after rising through the third driving cylinder 42. Then, the first suction cup 332 rises and the second suction cup 421 falls. The corresponding first suction cup 332 and second suction cup 421 open the opening of the packaging bag, making it easier for the eye mask to enter the packaging bag. Preferably, the cylinder body of the first driving cylinder 51 can be fixedly connected to the support platform 41, so that the positions of the first driving cylinder 51 and the third driving cylinder 42 are on the same straight line, ensuring smoother linkage between the two in the process.

[0029] Preferably, the frame 1 is provided with a placement plate 11 and a second motor. The placement plate 11 is located between the fixed plate 33 and the support platform 41. The second motor is located below the placement plate 11. The output end of the second motor is provided with a connecting shaft 12 and a second motor 13. The placement plate 11 is provided with a through hole 111 for accommodating the passage of the second suction cup 421. The placement plate 11 is used to place packaging bags. A connecting rod 112 is provided on the side of the placement plate 11 away from the second suction cup 421. One end of the connecting rod 112 is fixedly connected to the placement plate 11, and the other end is fixedly connected to the connecting shaft 12 and the second motor 13. The placement plate 11 is driven by the second motor to flip and unload the packaging bags located on the placement plate 11.

[0030] In this embodiment, the placement plate 11 is located between the fixed plate 33 and the support platform 41. This allows the packaging bag to be placed on the placement plate 11 after the flaring unit 4 has completed flaring, with the eye mask inside. The through hole 111 allows the second suction cup 421 to pass through, thus adsorbing the packaging bag and opening the bag opening. Finally, when the packaging bag containing the eye mask is placed on the placement plate 11, the second motor drives the connecting shaft 12 to rotate. The connecting shaft 12 and the second motor 13 drive the connecting rod 112 to swing, causing the placement plate 11 to tilt to one side. This allows the packaging bag containing the eye mask to be unloaded in the tilted direction. The through hole 111 avoids interference between the second suction cup 421 and the placement plate 11, thus opening the bag opening and facilitating the entry of the eye mask into the packaging bag. The second motor and the placement plate 11 allow the packaging bag containing the eye mask to be placed, completing the unloading process of the packaging bag.

[0031] Preferably, the eye mask bagging device further includes an opening unit 7 for opening the packaging bag. The opening unit 7 includes a second lead screw module 71, a second optical axis module, a support frame 72, a third motor 73, and a turntable 74. The second lead screw module 71 and the second optical axis module are disposed on both sides of the frame 1 and arranged along the length of the frame 1. The two ends of the support frame 72 are respectively connected to the second lead screw module 71 and the second optical axis module, and the support frame 72 can move along the length of the frame 1 through the second lead screw module 71. The third motor 73 is connected to the support frame 72, and the output end of the third motor 73 is vertically downward. The turntable 74 is fixedly connected to the output end of the third motor 73. The outer peripheral wall of the turntable 74 has two transmission rods 731 symmetrically arranged around the turntable 74 as the axis. One end of each of the two transmission rods 731 is eccentrically hinged to the bottom of the turntable 74. The support frame 72 also has a first plate 732. The first plate 732 and the second plate 733 are arranged side by side. The first plate 732 and the second plate 733 are slidably connected to the support frame 72 and can move along the width direction of the frame 1. The first plate 732 and the second plate 733 are both located below the turntable 74. The first plate 732 and the second plate 733 are respectively vertically corresponding to two transmission rods 731. The other end of one transmission rod 731 is hinged to the first plate 732 below it, and the other end of the other transmission rod 731 is hinged to the second plate 733 below it. The third motor 73 drives the turntable 74 to rotate, so as to drive the first plate 732 and the second plate 733 to move towards each other. The first plate 732 and the second plate 733 are both provided with a spreading block 734. The spreading block 734 is used to laterally spread open the bag opening of the packaging bag when the first plate 732 and the second plate 733 move towards each other.

[0032] Through the above design, the second lead screw module 71 can drive the support frame 72 to move along the length of the frame 1, and the second optical axis module provides guidance to ensure that the support frame 72 moves horizontally. Specifically, the two transmission rods 731 can drive the first plate 732 and the second plate 733 to move horizontally closer or further apart. The two transmission rods 731 are driven by the turntable 74, which is driven to rotate by the third motor 73. When the third motor 73 rotates clockwise, the first plate 732 and the second plate 733 move horizontally closer to each other; when the third motor 73 rotates counterclockwise, the first plate 732 and the second plate 733 move horizontally further apart. The support frame 72 moves horizontally along the length of the frame 1 via the second lead screw module 71. When the device moves in the 10-degree direction and approaches the flaring unit 4, the spreading block 734 will be inserted into the bag opening of the packaging bag through the flaring unit 4. Driven by the third motor 73, the first plate 732 and the second plate 733 move horizontally away from each other, thereby causing the spreading block 734 to move away from each other to open the bag opening, thus facilitating the insertion of the eye mask into the packaging bag. The two ends of the transmission rod 731 are respectively hinged to the bottom of the turntable 74 and the corresponding plate. When the turntable 74 rotates, one end of the transmission rod 731 will drive the other end to move, that is, drive the plate to move. The transmission rod 731 is symmetrically arranged with the turntable 74 as the axis. Therefore, the first plate 732 and the second plate 733 will move horizontally closer or further away from each other.

[0033] Preferably, the support frame 72 is provided with a slide rail 721 arranged horizontally along the width direction of the frame 1, and both the first plate 732 and the second plate 733 are provided with sliders 735, which are slidably connected to the slide rail 721; the first plate 732 is located on the side of the second plate 733 near the material rack 34, and the first plate 732 is provided with a receiving groove for accommodating the opening block 734 of the second plate 733 to pass through and move.

[0034] In the above design, the slide rail 721 and the slider 735 ensure that the first plate 732 and the second plate 733 can move horizontally along the length direction of the slide rail 721. The first plate 732 has a receiving groove, and the opening block 734 on the second plate 733 passes through the receiving groove and corresponds to the opening block 734 on the first plate 732. The opening block 734 on the first plate 732 and the second plate 733 can further open the bag opening, making it easier for the eye mask to enter the bag. The receiving groove can also prevent interference between the opening block 734 on the second plate 733 and the first plate 732. On the other hand, when the support frame 72 moves along the length direction of the frame 1 under the drive of the second screw module 71, it will drive the first plate 732 and the second plate 733 to move together, so that the opening block 734 can be inserted into the bag to open the bag opening.

[0035] Preferably, the frame 1 is also provided with an inclined guide plate 14. The inclined upward end of the guide plate 14 is in contact with the inclined downward end of the placement plate 11 when it is flipped. The guide plate 14 is used to guide the packaging bag located on the placement plate 11 to discharge. The guide plate 14 is provided with a guide piece 141. One end of the guide piece 141 is fixedly connected to the guide plate 14, and the other end is suspended.

[0036] In this embodiment, the guide plate 14 can receive the packaging bags that are flipped and unloaded from the placement plate 11. The guide piece 141 ensures that as the packaging bags slide downwards, the downward-sloping end first contacts the external collection frame, and then they are collected horizontally in the collection frame. It should be noted that the collection frame is arranged one-to-one with the positions of multiple packaging bags. The collection frame makes it convenient for workers to collect the unloaded packaging bags and carry out the next step of vacuum sealing and packaging. The elastically designed guide piece 141 can provide a cushioning effect for the packaging bags, avoiding excessive friction between the packaging bags and the guide plate 14. The elastic guide piece 141 can also provide a spring force to the bottom of the packaging bags, so that the packaging bags tend to be collected horizontally in the collection frame, which facilitates the operation of workers.
