Description

Technical Field

[0001] The utility model relates to the technical field of tape sticking machines, in particular to a sealing tape sticking machine for corrugated cardboard boxes. Background Art

[0002] Corrugated cardboard boxes are common and widely used packaging products, which have penetrated into all aspects of our daily life. Because of their extremely wide application range, their consumption has always been at the forefront of various packaging products; corrugated cardboard boxes are an ideal packaging container. It has the characteristics of being light, strong, shock-absorbing and suitable for mechanized production; after the corrugated cardboard box is packed with items, it is necessary to seal the opening of the corrugated cardboard box with tape. Under the condition of a large number of packaging boxes to be sealed, a sealing tape sticking machine appears, which can improve the sealing efficiency, reduce manual operation and ensure the consistency of the sealing quality.

[0003] The sealing tape sticking machine uses two groups of conveyor belts. The cardboard box is placed between the two groups of conveyor belts and pushed under the sticking machine. However, the widths of the corrugated cardboard packaging boxes of different items are different, which requires adjusting the distance between the conveyor belts. However, the distance between the conveyor belts is fixed. If adjustment is needed, the conveyor belts need to be disassembled, adjusted to the appropriate width and then fixed. The disassembly and assembly are time-consuming and laborious, reducing the convenience of use. At the same time, due to the different heights of the corrugated cardboard packaging boxes, the two groups of conveyor belts used in the existing sealing tape sticking machine are located on both sides of the lower end of the corrugated cardboard packaging box. During transportation, due to the different weights and shapes of the items inside the corrugated cardboard packaging box, the center of gravity is different. Since the two groups of conveyor belts are located on both sides of the lower end of the corrugated cardboard packaging box, the contact area between the conveyor belts and the corrugated cardboard box is limited. During the pushing process of the corrugated cardboard packaging box, when the center of gravity is unstable, the corrugated cardboard packaging box is prone to skew when entering, resulting in the tape sticking machine being unable to completely stick the tape at the sealing position of the corrugated cardboard packaging box, causing an opening and reducing the sealing quality.

When the left-right hand lead screw 10 rotates forward and backward, it can drive the two sets of sliding blocks 9 to approach or move away from each other.

[0022] Wherein, the upper surfaces at both ends of the bottom plate 12 are respectively fixedly connected with slide rails 17. Both sides of the slide rails 17 are in mutual communication with the inside of the slide rails 17. One set of first ear plates 18 are respectively arranged on the opposite sides of the two sets of slide rails 17. The lower ends of the two sets of first ear plates 18 are fixedly connected to the upper surface of the bottom plate 12. Through holes are provided on the side surfaces at the upper ends of the two sets of first ear plates 18. Two sets of second ear plates 19 are arranged on the upper surface of the middle part of the bottom plate 12. The lower ends of the second ear plates 19 are fixedly connected to the upper surface of the bottom plate 12. Through holes are provided on the side surfaces at the upper ends of the two sets of second ear plates 19.

[0023] Among them, the conveying component 5 includes a conveyor belt 20, rollers 21 and connecting plates 22. The outer surface of the conveyor belt 20 is attached to the outer surface of the carton body 7. A set of rollers 21 are respectively arranged inside both ends of the conveyor belt 20. A set of connecting plates 22 are respectively arranged at the upper and lower ends of the two sets of rollers 21. Through holes are formed in the upper surfaces of one ends of the two sets of connecting plates 22. The upper and lower ends of the two sets of rollers 21 are respectively rotatably connected to the through holes in the upper surfaces of one ends of the two sets of connecting plates 22. A driven bevel gear 23 is fixedly connected to the outer surface of the upper end of one of the sets of rollers 21. A driving bevel gear 24 is engaged above the driven bevel gear 23. A driving motor 25 is arranged at one end of the driving bevel gear 24. The power output end of the driving motor 25 is fixedly connected to one end of the driving bevel gear 24. The lower surface of the driving motor 25 is fixedly connected to the upper surface of the connecting plate 22 at the upper end of one of the sets of rollers 21. The driving motor 25 is electrically connected to an external power source. When the driving motor 25 is started, the rotation of the power output end of the driving motor 25 drives the driving bevel gear 24 to rotate. When the driving bevel gear 24 rotates, it engages the driven bevel gear 23 to rotate. When the driven bevel gear 23 rotates, it drives the roller 21 to rotate inside the through hole in the upper surface of one end of the connecting plate 22. When the roller 21 rotates, the conveyor belt 20 is driven to rotate under the action of the friction force between the outer surface of the roller 21 and the inner wall of the conveyor belt 20. When the conveyor belt 20 rotates, due to the friction force between the conveyor belt 20 and the outer surface of the carton body 7, and at the same time under the rotation of the roller 3 on the lower surface of the carton body 7, the conveyor belt 20 drives the carton body 7 to move to the lower surface of the tape gluing machine body 16.

[0024] Among them, both ends of the transmission rod 13 are respectively rotatably connected to the through holes in the upper side surfaces of the two sets of first ear plates 18. Gears 14 are respectively fixedly connected to both ends of the transmission rod 13. A rack 15 is engaged on one side of the two sets of gears 14. The racks 15 on one side of the two sets of gears 14 are respectively slidably connected to the inside of the slide rails 17 at both ends of the bottom plate 12. The racks 15 on the side away from the gears 14 penetrate through the slide rails 17 and are respectively fixedly connected to the connecting plates 22 at the upper and lower ends of the two sets of rollers 21 away from the rollers 21. A worm gear 26 is fixedly connected to the middle of the transmission rod 13. A worm 27 is engaged below the worm gear 26. Both ends of the worm 27 are respectively rotatably connected to the through holes in the upper side surfaces of the two sets of second ear plates 19. A rotating wheel 28 is fixedly connected to one end of the worm 27. The rotating wheel 28 facilitates the operator to hold and rotate the worm 27. When the rotating wheel 28 rotates, it drives the worm 27 to rotate inside the through holes in the upper side surfaces of the two sets of second ear plates 19. When the worm 27 rotates, it engages the worm gear 26 to rotate. When the worm gear 26 rotates, it drives the transmission rod 13 to rotate inside the through holes in the upper side surfaces of the two sets of first ear plates 18. When the transmission rod 13 rotates, it drives the gears 14 at both ends of the transmission rod 13 to rotate at the same time. When the gears 14 rotate, they engage the racks 15, causing the racks 15 to slide inside the slide rails 17. When the racks 15 slide, they drive the rollers 21 and the conveyor belt 20 to rise or fall through the connecting plates 22. The lifting is controlled by the operator rotating the rotating wheel 28 forward and backward.

[0025] Among them, the upper ends of the two groups of sliding blocks 9 pass through the guide rail 8 and extend to the upper surface of the guide rail 8. The two groups of sliding blocks 9 can slide along the guide rail 8 to approach or move away from each other. The upper ends of the two groups of sliding blocks 9 respectively pass through between two of the roller shafts 3. The two groups of sliding blocks 9 can approach or move away from each other between the two groups of roller shafts 3, while not interfering with the rotation of the roller shafts 3. The upper ends of the two groups of sliding blocks 9 are respectively fixedly connected to the lower surfaces of the two bottom plates 12. When the sliding blocks 9 approach or move away from each other, the two bottom plates 12 are driven to approach or move away from each other.

[0026] The working principle provided by the present utility model is as follows: When it is necessary to seal the carton box body 7, the operator first places the carton box body 7 on the upper surface of the roller shafts 3. The operator starts the servo motor 11, and the power output end of the servo motor 11 rotates to drive the rotation of the positive and negative thread lead screw 10. When the positive and negative thread lead screw 10 rotates, the external positive thread and negative thread of the positive and negative thread lead screw 10 are respectively threadedly connected to the threaded holes at one ends of the two groups of sliding blocks 9, so that the two groups of sliding blocks 9 slide along the guide rail 8 and approach each other. When the two groups of sliding blocks 9 approach each other, the two bottom plates 12 are driven to slide along the upper surface of the mounting plate 2 and the upper surface of the roller shafts 3 and approach each other. When the two bottom plates 12 approach each other, the conveyor belts 20 in the two conveying components 5 are driven to fit on the outer surfaces of both sides of the carton box body 7. When the height of the carton is relatively high, the operator holds and rotates the rotating wheel 28. When the rotating wheel 28 rotates, it drives the worm 27 to rotate inside the through holes on the side surfaces of the upper ends of the two second ear plates 19. When the worm 27 rotates, it meshes with the worm gear 26 to rotate. While the worm gear 26 rotates, it drives the transmission rod 13 to rotate inside the through holes on the side surfaces of the upper ends of the two first ear plates 18. When the transmission rod 13 rotates, the gears 14 at both ends of the transmission rod 13 are driven to rotate. When the gears 14 rotate, they mesh with the rack 15, so that the rack 15 slides inside the slide rail 17. When the rack 15 slides, it drives the drum 21 and the conveyor belt 20 to rise and fall through the connecting plate 22, so that the conveyor belt 20 can be adjusted to the middle position of the carton box body 7. After the adjustment of the conveyor belt 20 is completed, the operator starts the driving motor 25. The power output end of the driving motor 25 rotates to drive the active bevel gear 24 to rotate. When the active bevel gear 24 rotates, it meshes with the driven bevel gear 23 to rotate. When the driven bevel gear 23 rotates, it drives the drum 21 to rotate inside the through hole on the upper surface of one end of the connecting plate 22. When the drum 21 rotates, due to the frictional force between the outer surface of the drum 21 and the inner wall of the conveyor belt 20, the conveyor belt 20 is driven to rotate. When the conveyor belt 20 rotates, due to the frictional force between the conveyor belt 20 and the outer surface of the carton box body 7 and the rotation of the roller shafts 3 on the lower surface of the carton box body 7, the conveyor belt 20 drives the carton box body 7 to move to the lower surface of the tape gluing machine body 16, and the tape gluing machine body 16 seals the opening on the upper surface of the carton box body 7.
