DETAILED DESCRIPTION

[0023] Figures 1 to 6 The schematic diagram of the structure of the automatic carton sealing machine embodiment provided by the present invention comprises four supporting columns 1 distributed in a rectangular shape, a driving mechanism, a lifting frame 2, a movement 3, a sensing component 4 and a lower limit sensor 5, wherein a driving mechanism is arranged at the top in the middle of the four supporting columns 1, the lifting frame 2 is movably mounted on the four supporting columns 1, and the lifting frame 2 is located below the driving mechanism, and the driving mechanism drives the lifting frame 2 to rise and fall along the supporting columns 1, the movement 3 and the sensing component 4 are respectively arranged on the lifting frame 2, and the sensing component 4 is located in front of the movement 3, a control box 6 is arranged on the top of the supporting column 1, and lower limit sensors 5 are respectively arranged on both sides of the lifting frame 2, and the control box 6 is electrically connected to the driving mechanism, the sensing component 4 and the lower limit sensor 5, respectively.

[0024] During operation, the present invention is connected to the assembly line 10 through four supporting columns 1, which is conducive to saving space and can integrate the present invention with the existing assembly line 10. The driving mechanism drives the lifting frame 2 to rise and fall along the supporting column 1, and the lifting frame 2 drives the movement 3, the sensing component 4, and the lower limit sensor 5 to rise and fall. When the lower limit sensor 5 reaches the initial working height, the driving mechanism stops working, and the assembly line 10 starts to convey the carton. When the carton passes through the carton sealing machine, first, the carton pushes the sensing component 4 upward. After the sensing component 4 is subjected to the upward force, it sends a signal to the control box 6. The control box 6 controls the driving mechanism to drive the lifting frame 2 to drive the movement 3 and the sensing component 4 to rise. When the sensing component 4 rises to a certain height and is no longer subjected to the upward force of the carton, the control box 6 controls the driving mechanism to close, and the carton continues to be conveyed forward to the movement 3 through the sensing component 4 for sealing. The height of the pressing box can be automatically controlled and adjusted according to the height of the carton through the sensing component 4, which is suitable for bulging cartons of various heights and sizes.

[0025] The driving mechanism includes a mounting frame 71, a motor 72, a worm screw lifter 73, a threaded screw 74, and a nut 75. The mounting frame 71 is arranged at the top of the four support columns 1, the motor 72 is arranged on the mounting frame 71, the motor 72 is connected to the worm screw lifter 73, the worm screw lifter 73 and the nut 75 are respectively mounted on the threaded screw 74, and the worm screw lifter 73 is fixedly connected to the mounting frame 71, and the nut 75 is arranged on the lifting frame 2.

[0026] When the driving mechanism drives the lifting frame 2 to move up and down, the motor 72 drives the threaded screw 74 to rotate through the turbine screw lifter 73, and the threaded screw 74 rotates to drive the nut 75 to move up and down along the threaded screw 74, and the nut 75 drives the lifting frame 2 to move up and down.

[0027] The lifting frame 2 includes two symmetrical connecting rods 21, two movable side frames 22 are connected between the two connecting rods 21, each side frame 22 is provided with a clamping wheel 23, and a slider 24 is provided at the end of each connecting rod 21. The slider 24 is movably mounted on the support column 1, wherein a mounting plate 25 is connected between the two sliders 24, and the induction component 4 and the nut 75 are arranged on the mounting plate 25.

[0028] When the lifting frame 2 is raised or lowered, it is raised or lowered along the support column 1 through the slider 24. When the assembly line 10 transports the cartons, the two side frames 22 can be used to guide and orient the cartons so that the cartons can accurately enter under the movement 3. The clamping wheels 23 on the side frames 22 can make the cartons transported more smoothly.

[0029] The connecting rod 21 is connected to the side frame 22 through an adjusting assembly. The adjusting assembly includes a connecting arm 26 and a moving block 27. Both ends of the connecting arm 26 are respectively connected to the side frame 22 and the moving block 27. The moving block 27 is movably mounted on the connecting rod 21.

[0030] When adjusting the distance between the two side frames 22, the moving block 27 can be pushed to the position of the connecting rod 21, so as to adjust the distance between the two side frames 22 so that the distance between the two side frames 22 is adapted to the size of the carton.

[0031] The sensing assembly 4 includes a sensing plate 41, a connecting column 42, a sensing spring 43, a sleeve 44, a limit switch 45, and a trigger piece 46. The sleeve 44 is connected to the mounting plate 25. The connecting column 42 is sleeved with the sensing spring 43. One end of the connecting column 42 is movably arranged in the sleeve 44. The other end of the connecting column 42 is connected to the sensing plate 41. The trigger piece 46 is arranged on the sensing plate 41. The limit switch 45 is arranged on the mounting plate 25, and the limit switch 45 is located on the movement trajectory of the trigger piece 46.

[0032] When the carton is transported through the sensing assembly 4, if the height of the carton is too high, the carton will push the sensing plate 41 upward. After the sensing plate 41 is subjected to the upward force, the sensing plate 41 drives the connecting column 42 to rise along the sleeve 44 and compress the sensing spring 43. The trigger plate 46 rises with the sensing plate 41. When the trigger plate 46 touches the limit switch 45, the limit switch 45 is triggered and sends a signal to the control box 6. The control box 6 controls the motor 72 to start and drive the lifting frame 2 to rise. When the lifting frame 2 rises to a certain height, the carton no longer applies an upward force to the sensing plate 41, the sensing spring 43 resets, the trigger plate 46 and the limit switch 45 separate, and the control box 6 controls the motor 72 to turn off.

[0033] It also includes a buffer frame, which includes a top frame 81, a bottom frame 82, a buffer column 83, a buffer spring 84, and a buffer tube 85. The top frame 81 is connected to the connecting rod 21, the buffer tube 85 is arranged on the top frame 81, the buffer column 83 is movably arranged in the buffer tube 85, and the bottom end of the buffer column 83 is connected to the bottom frame 82, the buffer spring 84 is mounted on the buffer column 83, and the buffer spring 84 is located between the top frame 81 and the bottom frame 82, and the movement 3 is arranged on the bottom frame 82.

[0034] When the carton reaches below the movement 3 and the movement 3 presses and seals the carton, the bottom frame 82 is subjected to an upward force, and the bottom frame 82 drives the buffer column 83 to rise along the buffer tube 85 and compress the buffer spring 84, thereby playing a role in buffering and reducing impact force.

[0035] The movement 3 includes two side panels 31 arranged opposite to each other, and the two side panels 31 are respectively connected to the bottom frame 82. A front sealing rod 32 and a rear sealing rod 33 are rotatably arranged between the two side panels 31. A front pressure wheel 34 is rotatably arranged on the front sealing rod 32, and a rear pressure wheel 35 is rotatably arranged on the rear sealing rod 33. A connecting rod 36 is connected between the front sealing rod 32 and the rear sealing rod 33 to make the front sealing rod 32 and the rear sealing rod 33 rotate synchronously. A support rod 37 is connected between the two side panels 31, and a return spring 38 is connected between the support rod 37 and the rear sealing rod 33. A cutting assembly is arranged on one of the side panels 31, and a tape reel 39 is arranged on the other side panel 31.

[0036] The heights h of the front sealing rod 32 and the rear sealing rod 33 are 15.5 cm respectively.

[0037] The cutting assembly includes a connecting plate 91, a driving spring 92, a box-pressing rod 93, and a cutter 94. The connecting plate 91 is rotatably disposed on the side plate 31. A driving spring 92 is disposed between the connecting plate 91 and the side plate 31. The box-pressing rod 93 and the cutter 94 are respectively disposed on the connecting plate 91, and the box-pressing rod 93 is located below the cutter 94. A guide plate 95 is disposed at the outer end of the cutter 94.

[0038] The box-pressing rod 93 is made of thickened metal sheet.

[0039] The adhesive tape is placed on the tape reel 39 and opened, so that the head of the adhesive tape passes through the adhesive guide roller 96 and contacts the front pressing wheel 34. The adhesive guide roller 96 and the tape reel 39 are arranged on the same side plate 31. The assembly line 10 drives the carton to move forward. When the carton contacts the front pressing wheel 34, the head of the adhesive tape is pressed against the side of the carton, and the front sealing rod 32 rotates. The front sealing rod 32 drives the rear sealing rod 33 to rotate through the connecting rod 36. At this time, the front sealing rod 32 and the rear sealing rod 33 rotate inward synchronously. At the same time, when the carton enters the box pressing rod 93, the box pressing rod 93 presses on The upper surface of the carton is pressed flat by the box pressing rod 93, and at the same time, the box pressing rod 93 drives the connecting plate 91 to lift up, so that the driving spring 92 is in a tensioned state, and the carton continues to move forward. When the carton leaves the box pressing rod 93, the driving spring 92 rebounds and relaxes to drive the connecting plate 91 to drive the box pressing rod 93 and the cutter 94 to reset and cut the tape. When the rear pressing wheel 35 leaves the upper surface of the carton, the rear sealing rod 33 is reset under the action of the reset spring 38, and the rear sealing rod 33 rotates to press the tail of the tape against the side of the carton to complete the sealing action.

[0040] By setting the height h of the front sealing rod 32 and the rear sealing rod 33 at 15.5 cm respectively, it is possible to increase the length of the sealing on the side of the carton, and achieve large-span passage without interfering with the carton.

[0041] The box-pressing rod 93 is a thickened metal plate that can lower and flatten the height of the bulge on the upper surface of the carton. A guide plate 95 is provided at the end of the cutter 94. When the carton passes through the box-pressing rod 93, the guide plate 95 can be used to prevent the cutter 94 from contacting the carton.
