DETAILED DESCRIPTION

[0029] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0030] Reference Figures 1 to 7 As shown, the present invention is a cigarette circulation box sealing device, comprising a transmission belt 1 for conveying a circulation box 9, the two sides of the transmission belt 1 are fixedly connected by a conveying side frame 11, and the lower part of the conveying side frame 11 is supported by a bracket leg 13. The circulation box 9 has an opening on the side and a box cover 91 made of soft cloth is connected to the opening. The circulation box 9 is made of hard cloth, and cigarettes are placed inside the circulation box 9. Figure 4 As shown, the top surface of the circulation box 9 and the box cover 91 are connected with Velcro 92 that can be matched with each other, and the box cover 91 is fixed to the circulation box 9 through the Velcro 92 to achieve the sealing of the circulation box 9. In order to ensure that the cigarettes will not leak out, the box cover 91 is pulled back as far as possible and then fixed with Velcro.

[0031] A lifting cylinder 2 with an output shaft facing upward is connected to the lower side of the transmission belt 1. Specifically, Figure 5 As shown, there are two lifting cylinders 2 and they are linked and controlled. A lower mounting plate 24 is fixedly connected to the bracket leg 13 of the transmission belt 1, and the lifting cylinder 2 is fixed on the lower mounting plate 24. The output shaft end of the lifting cylinder 2 is connected to the top plate 21, and the top plate 21 is driven to move up and down by the lifting cylinder 2. A box closing swivel 22 is fixed on both sides of the top surface of the top plate 21, and a horizontal box closing shaft 23 is rotatably connected to the box closing swivel 22. The outer surface of the box closing shaft 23 is fixedly connected to the box closing support plate 3 by screws, and one end of the box closing shaft 23 is connected to the rotating cylinder 31. Specifically, the rotating cylinder 31 is connected to the box closing shaft 23 through a chain transmission group 32, and the rotation of the rotating cylinder 31 drives the box closing support plate 3 to flip through the chain transmission group 32 and the box closing shaft 23.

[0032] A photoelectric sensor 7 is connected to one side of the transmission belt 1. The photoelectric sensor 7 is also called a photoelectric switch, which is used to sense whether the circulation box has reached the set position. A PLC controller is also included. The PLC controller uses the Siemens S7-200 model. The PLC controller is electrically connected to the photoelectric sensor 7, the lifting cylinder 2 and the rotating cylinder 31. During operation, after the cigarette packing process is completed, the open circulation box 9 is pushed onto the transmission belt 9 of the device. When the circulation box 9 is conveyed to the position of the lifting cylinder 2, that is, the position where the box needs to be sealed, the box cover 91 is placed on the box closing pallet 3. At this time, the photoelectric sensor 7 senses that the circulation box 9 is in place and sends a signal to the PLC controller. The PLC controller controls the conveyor belt to stop. After the circulation box 9 stops, the lifting cylinder 2 extends upward. After extending to the top, the rotating cylinder 31 drives the box closing pallet 3 to rotate inward, and the box cover 91 placed on the box closing pallet 3 is turned over to the top of the circulation box 9. The box cover 91 is fixed to the circulation box 9 through the Velcro 92 to achieve the sealing of the circulation box.

[0033] The side of the transmission belt 1 away from the jacking cylinder 2 is connected to a push cylinder frame 41, and the push cylinder 4 is connected to the push cylinder frame 41. Figure 5 , 7 As shown, the output shaft of the horizontal push cylinder 4 faces one side of the conveyor belt 1. The output shaft end of the horizontal push cylinder 4 is connected to a horizontal upper connecting plate 5, and the horizontal push cylinder 4 can drive the upper connecting plate 5 to move forward and backward. A clamping claw rotating seat 65 is installed on the left and right sides above the top surface of the upper connecting plate 5, and a clamping claw rotating shaft 64 is rotatably connected to the clamping claw rotating seat 65. The two ends of the clamping claw rotating shaft 64 are connected to the clamping claw 66. The rear side of the clamping claw rotating shaft 64 is connected to a clamping claw driving assembly that can drive the clamping claw rotating shaft 64 to rotate and thus open and close the clamping claw 66. The horizontal push cylinder 4 and the clamping claw driving assembly are both electrically connected to the PLC controller. When the lifting cylinder 2 extends upward and the rotating cylinder 31 drives the closing plate 3 to rotate inward, the pushing cylinder 4 pushes out the upper connecting plate 5, and the closing plate 3 first flips the box cover 91 onto the upper connecting plate 5. Then the clamping claw 66 rotates downward to clamp the box cover 91, and the pushing cylinder 4 contracts to drag the box cover 91 backward. After it is dragged into place, the clamping claw 66 is released, and the box cover 91 falls and is fixed to the circulation box 9 by the Velcro 92. The above-mentioned two processes of clamping and dragging with the clamping claw 66 can further ensure that the box is sealed in place to prevent cigarettes from leaking out of the gap between the box cover 91 and the circulation box 9.

[0034] The clamping jaw driving assembly includes a clamping cylinder 6 whose rear end is rotatably connected to a cylinder rotating seat 61 on the upper connecting plate 5, the output shaft end of the clamping cylinder 6 faces forward, and the output shaft end is connected to a cylinder hinge head 62, and a hinge block 63 is fixedly connected to the clamping jaw rotating shaft 64. In this embodiment, the hinge block 63 is vertical to the clamping jaw 66, and the cylinder hinge head 62 is hinged to the free end of the hinge block 63. After the clamping cylinder 6 is extended, it pushes the clamping jaw rotating shaft 64 to rotate through the hinge block 63, thereby causing the clamping jaw 66 to rotate downward. Figure 5 and Figure 6These are the two states when the clamping jaw 66 is opened and pressed down. Figure 5 The state is when the lifting cylinder 2 extends upward, the rotating cylinder 31 drives the closing plate 3 to rotate inward to place the box cover 91 on the upper connecting plate 5; Figure 6 for Figure 5 After the state, the clamping claw 66 clamps the box cover 91 and contracts through the push cylinder 4 to drag the box cover 91 backward. This is the state where the lifting cylinder 2 and the rotating cylinder 31 also return to their original positions, waiting for the instruction of the PLC controller when the next circulation box 9 is in place.

[0035] The bottom surface of the clamping jaw 66 is connected with an anti-skid rubber layer, which can effectively prevent the clamping jaw 66 from accidentally separating when clamping the box cover 91 and dragging it backwards, resulting in incomplete sealing of the box.

[0036] A positioning baffle 12 is connected to the side of the front end of the transmission belt 1. When the circulation box 9 is automatically pushed onto the transmission belt 1 after the cigarette packing process is completed, the circulation box 9 is blocked and positioned by the positioning baffle 12 to ensure that each circulation box 9 is in the same position when being transported on the conveyor belt 1 and is in the set position, thereby ensuring the quality of the box sealing.

[0037] The front side of the box closing pallet 3 is provided with a box cover guide rod 8 connected to the side of the conveyor belt 1. Figure 5 , 6 As shown, the box cover guide rod 8 is narrow at the front and wide at the rear, which plays a guiding role for the box cover 91. When the circulating box 9 is pushed onto the conveyor belt 1, the box cover 91 is placed on the conveying side frame 11 of the transmission belt 1 located on the side of the lifting cylinder 2. In this way, when the circulating box 9 is conveyed backward until it is conveyed to the box sealing position, the box cover 91 is easily blocked by the side of the box closing pallet 3 and cannot be placed on the top surface of the box closing pallet 3. By setting the box cover guide rod 8, the box cover 91 first slides from the conveying side frame 11 to the box cover guide rod 8, and then the angle between the box cover 91 and the conveyor belt 1 gradually increases when sliding on the box cover guide rod 8 which is narrow at the front and wide at the rear, and finally can be placed on the top surface of the box closing pallet 3.

[0038] A step 111 is formed between the top surface of the conveying side frame 11 and the top surface of the conveying belt 1 because the conveying side frame 11 is slightly lower. A limiting groove matching the step 111 is provided on the bottom surface of the circulation box 9. The limiting groove matches the step 111 to avoid left and right relative movement of the circulation box 9 and the conveyor belt during transportation, thereby further ensuring the position accuracy of the circulation box 9 on the conveyor belt.

[0039] Working process: after the cigarette packing process is completed, the opened circulation box 9 is pushed onto the transmission belt 9 and limited by the positioning baffle 12, and the circulation box 9 is transported backward; when it is transported to the position where the box needs to be sealed, the box cover 91 is guided by the box cover guide rod 8 and placed on the box closing pallet 3. At this time, the photoelectric sensor 7 senses that the circulation box 9 is in place and sends a signal to the PLC controller, and the PLC controller controls the conveyor belt to stop; after the circulation box 9 stops, the lifting cylinder 2 extends upward, and after extending to the top, the rotating cylinder 31 drives the box closing pallet 3 to rotate inward, and at the same time, the horizontal push cylinder 4 pushes out the upper connecting plate 5, and the box closing pallet 3 first flips the box cover 91 onto the upper connecting plate 5, and then the clamping cylinder 6 drives the clamping claw 66 to rotate downward to clamp the box cover 91, and the horizontal push cylinder 4 contracts to drag the box cover 91 backward. After being dragged into place, the clamping claw 66 is released, and the box cover 91 falls and is fixed to the circulation box 9 by the Velcro 92.
