After the adjustment is completed, the clamping device can be manually locked; material sorting cylinders 102 are provided on the left and right sides of the feeding conveyor belt 1, which can block and sort the incoming box body 9. Conveying wheels 103 are also provided on the left and right sides of the end of the feeding conveyor belt 1. The conveying wheels 103 are driven by a motor, and the conveying wheels 103 are fitted with the side walls of the box body 9 to provide power for the box body 9 to enter the glue spraying mechanism.

[0043] A carton pushing assembly 2 is arranged below the feed conveyor belt 1. The carton pushing assembly 2 includes a horizontal cylinder 201, a vertical cylinder 202 and a push plate 203. The horizontal cylinder 201 drives the vertical cylinder 202 to move along the direction of the feed conveyor belt 1, and the vertical cylinder 202 drives the push plate 203 to move along the vertical direction. There is a gap in the middle of the feed conveyor belt 1. When the box body 9 moves to the end of the feed conveyor belt 1, the vertical cylinder 202 drives the push plate 203 to move upward and rise from the gap. The horizontal cylinder 201 drives the push plate 203 to push the box body 9 in the horizontal direction, and pushes the box body 9 into the glue spraying mechanism.

[0044] like Figure 4 As shown, the glue spraying mechanism includes a glue spraying conveyor belt 3, and the feeding mechanism conveys the box body 9 to the glue spraying conveyor belt 3. The glue spraying conveyor belt 3 includes a conveying platform 301. The left and right sides of the conveying platform 301 are provided with annular chains 302 driven by a motor. A number of levers 303 arranged at equal intervals are connected between the chains 302 on both sides. The chains 302 push the box body 9 to move forward through the levers 303. A row of balls 304 are arranged in the middle of the conveying platform 301 along the conveying direction. The lever 303 moves above the balls 304. The balls 304 make it easier for the box body 9 to move along the conveying platform 301. There are side panels on both sides of the conveying platform 301. When the box body 9 moves, the two sides are in contact with the side panels, which guide the box body 9 and prevent the box body 9 from shifting during transportation. The distance between the two side panels is adjustable.

[0045] The glue spraying conveyor belt 3 is provided with side leaf glue spraying devices 7 on both sides, and the side leaf glue spraying devices 7 are used to spray glue on the side walls of the box body 9. The side leaf glue spraying devices 7 also include a large leaf glue spraying device 8 movably arranged above the glue spraying conveyor belt 402. The large leaf glue spraying device 8 moves along the width direction of the glue spraying conveyor belt 3. The frame 10 is provided with a guide rail along the width direction of the glue spraying conveyor belt 3. The large leaf glue spraying device 8 moves through the guide rail.

The glue spraying head of the side leaf glue spraying device 7 can adjust its position along the conveyor belt direction and the height direction. The glue spraying head of the large leaf glue spraying device 8 can be adjusted along the height direction. The frame crossbeam on which the large leaf glue spraying device 8 is installed drives the screw rod through the motor to adjust the height.

[0046] A material-blocking cylinder is provided on the glue spraying conveyor belt 3, and the side leaf glue spraying device 7 and the material-blocking cylinder are arranged in sequence along the conveying direction of the glue spraying conveyor belt 3. When the box body 9 moves to be aligned with the side leaf glue spraying device 7, the piston rod of the material-blocking cylinder extends out and fits with the side of the box body 9 toward the capping mechanism to prevent the box body 9 from continuing to move forward.

[0047] Each time when the chain 302 drives the lever 303 to push the box 9 into the spraying area of ​​the side leaf spraying device 7, the side leaf spraying device 7 sprays glue on the moving box 9. After entering the spraying area of ​​the large leaf spraying device 8, the chain 302 will stop moving and wait for the large leaf spraying device 8 to finish spraying. After that, the chain 302 continues to drive the lever 303 to push the next box 9 in.

[0048] like Figures 5 to 8 As shown, the capping mechanism includes a capping conveyor belt 4, and the glue spraying conveyor belt 3 conveys the box body 9 to the capping conveyor belt 4, and also includes a leaflet closing device 5 and a pressing device 6 which are sequentially arranged above the capping conveyor belt 4.

[0049] The leaflet closing device 5 includes a leaflet support 501, below which a large leaf lower pressure plate 502 is obliquely arranged. The large leaf lower pressure plate 502 is inclined downward toward the conveying direction of the glue spraying conveyor belt 3. When the box body 9 passes under the leaflet closing device 5, the large leaf lower pressure plate 502 flips the large leaf 902 downward, so that the large leaf 902 changes from a vertical state to an inclined state, thereby completing the pre-compression before closing.

[0050] A leaflet closing cylinder 503 is obliquely arranged below the leaflet support 501. The leaflet closing cylinder 503 is inclined downward toward the conveying direction of the glue spraying conveyor belt 3. The piston rod of the leaflet closing cylinder 503 is extended to close the leaflet 901. An insert block is arranged at the end of the piston rod of the leaflet closing cylinder 503. The leaflet closing cylinder 503 contacts the leaflet 901 through the insert block. The two ends of the insert block are close to the two ends of the leaflet 901 to increase the contact area and make it more stable when closed.

[0051] The leaflet support 501 is provided with a horizontal plate 504 which is adjustable in the vertical direction, and is driven by a screw and a guide rod provided on the leaflet support 501. A hand wheel is provided on the top of the screw, and the horizontal plate 504 can be moved vertically along the guide rod by rotating the hand wheel. The horizontal plate 504 is provided with a vertical plate 505 which is adjustable along the conveying direction of the glue spraying conveyor belt 3. A guide rail is provided on the horizontal plate, and the vertical plate is fixed at any position of the guide rail by screws to realize the adjustment of the vertical plate 505 in the conveying direction. The leaflet support 501 is connected to the frame 10 by bolts and nuts, so that the leaflet support 501 can be adjusted in the width direction of the glue spraying conveyor belt 3.

[0052] The large leaf lower pressure plate 502 and the small leaf closing cylinder 503 are installed on the vertical plate 505, so that the large leaf lower pressure plate 502 and the small leaf closing cylinder 503 can be adjusted in height, conveying direction and width direction to improve applicability.

[0053] The pressing device 6 includes a pressing bracket 602, which is movably arranged along the direction of the glue spraying conveyor belt 3. A pressing module 601 that moves along the vertical direction is arranged on the pressing bracket 602. A servo motor 603 and a screw rod for driving the pressing module 601 to move are arranged on the pressing bracket 602. The pressing module 601 is moved up and down by the drive of the servo motor 603 and the screw rod and the guidance of the sliding rod; the pressing bracket 602 is connected to the frame 10 through the fixed plate 604, and the screw rod drives the nut on the fixed plate 604 to adjust, and the pressing bracket 602 is guided by two guide shafts and four linear bearings 605 installed on the back of the fixed plate 604 to adjust the position along the direction of the glue spraying conveyor belt 3.

[0054] The pressing module 601 includes a mounting frame 6011, on which a plurality of large-leaf pressing columns 6011 are arranged in the vertical direction. The large-leaf pressing columns 6011 move in the vertical direction. A buffer spring is arranged between the large-leaf pressing columns 6011 and the mounting plate. When the pressing module 601 moves downward, the large-leaf pressing columns 6011 overcome the elastic force of the buffer spring and move upward, and close the large leaf 902 downward. A pressing plate is connected to the bottom of the large-leaf pressing column 6011 to increase the contact area with the box body 9 to make the pressing more stable.

[0055] The mounting frame 6011 is located on both sides of the large leaf pressing column 6011 and is rotatably connected with the side leaf clamping plate 6013. The mounting frame 6011 is provided with a side leaf cylinder 6014 for driving the side leaf clamping plate 6013 to rotate. The side leaf cylinder 6014 is horizontally arranged. When the side leaf cylinder 6014 pushes the top end of the side leaf clamping plate 6013 outward, the bottom end of the side leaf clamping plate 6013 rotates inward to close the side leaf 903.

[0056] A side leaf guide rod 6015 is arranged on the mounting frame 6011 along the width direction of the glue spraying conveyor belt 3, and a side leaf support plate 6016 is slidably connected to the side leaf guide rod 6015, and the side leaf clamping plate 6013 is rotatably connected to the side leaf support plate 6016. A side leaf screw is rotatably connected to the mounting frame 6011, and the side leaf screw penetrates the side leaf support plate 6016 and is threadedly connected to the side leaf support plate 6016. When the side leaf screw is rotated, the two side leaf support plates 6016 move away from each other, thereby increasing the distance between the side leaf clamping plates 6013, and when the side leaf screw is rotated in the opposite direction, the two side leaf support plates 6016 move toward each other, thereby reducing the distance between the side leaf clamping plates 6013, so that the side leaf clamping plates 6013 can be suitable for boxes 9 of different widths.

[0057] A slewing bearing 606 is provided at the bottom end of the screw rod, and the screw rod is rotatably connected to the slewing bearing 606.
