[0022] The present invention will be further described below with reference to the following embodiments and accompanying drawings.

The conveyor belt 1 is a belt conveyor, which is conventional and will not be described in detail here. Baffles 101 are provided on both sides of the conveyor belt 1. The working surface of the conveyor belt 1 is provided for placing carton bodies 13. The working surface of the conveyor belt 1 cooperates with the two corresponding baffles 101 to form a feeding channel 102 for the carton bodies 13 to pass through.

[0024] The top surface of the gluing platform 2 cooperates with the working surface of the conveyor belt 1. A gantry 3 is provided on the gluing platform 2. A moving component 4 and a gluing unit 5 are provided on the gantry 3. The moving end of the moving component 4 is connected to the gluing unit 5. The moving component 4 moves the position of the gluing unit 5 in the horizontal and vertical directions. The gluing unit 5 is used to glue the cardboard.

[0025] The glue coating unit 5 includes a mounting plate 51, a glue coating roller 52 and a glue feeding cylinder 53. A connecting frame 501 is provided at the bottom of the mounting plate 51. The glue coating roller 52 is rotatably connected to the connecting frame 501. The glue feeding cylinder 53 is provided on the mounting plate 51, and the glue outlet 502 of the glue feeding cylinder 53 is located above the glue coating roller 52.

[0026] The moving assembly 4 includes a moving plate 41, a first translation mechanism 42 and a second translation mechanism 43. The moving plate 41 is a U-shaped plate. The two sides of the moving plate 41 are respectively located on the two side walls of the gantry 3. The moving plate 41 is slidably connected to the crossbeam of the gantry 3. The first translation mechanism 42 is a screw stepper motor. The translation end of the first translation mechanism 42 is connected to one side of the moving plate 41. The second translation mechanism 43 is fixedly connected to the other side of the moving plate 41. The second translation mechanism 43 is a telescopic cylinder. The translation end of the second translation mechanism 43 is connected to the mounting plate 51. The first translation mechanism 42 moves the gluing unit 5 laterally, and the second translation mechanism 43 moves the gluing unit 5 vertically.

[0027] The clamping mechanism 6 includes two clamping members 61 and a driving device 62. Two parallel slide grooves 202 are provided on the top surface of the gluing platform 2. A slider 601 is fixedly connected to the bottom of the clamping member 61. The two sliders 601 are respectively slidably connected in the two slide grooves 202, so that the two clamping members 61 are arranged relative to each other and are both slidably connected to the top surface of the gluing platform 2.

[0028] The side of the clamping member 61 extends into the feeding channel 102, and a mounting groove 201 is provided inside the gluing table 2. The driving device 62 is arranged in the mounting groove 201 and connects the two clamping members 61 through a synchronous transmission component 7. The synchronous transmission component 7 includes two driving bars 71 and a driving gear 72. The two driving bars 71 are spaced apart and arranged in parallel. The driving bar 71 is slidably connected to the mounting groove 201, and the slide groove 202 is connected to the mounting groove 201. The two driving bars 71 are fixedly connected to the two sliders 601 respectively, and the driving gear 72 is located between the two driving bars 71, and the driving bar 71 is meshed with the driving gear 72. The driving device 62 is a rotating motor, and the output shaft of the driving device 62 is connected to the driving gear 72, so that the two clamping members 61 are synchronously approached or moved away in the feeding channel 102 under the drive of the driving device 62.

[0029] When the gluing device is in use, the staff places the carton body 13 on the working surface of the conveyor belt 1. The two baffles 101 on the conveyor belt 1 limit the carton body 13 in the material transport channel. The two conveyor belts 1 have the same transport direction. The two conveyor belts 1 are used for feeding and discharging respectively. Preferably, the opposite sides of the two clamping members 61 are formed with matching walls 8. The matching walls 8 include abutment surfaces 81 and two guide surfaces 82. The two guide surfaces 82 are arranged oppositely. The guide surfaces 82 are formed when the clamping member 61 extends into the feeding channel 102. The guide surface 82 is arranged on the side of the carton body 13 and tilted toward the abutment surface 81. The guide surface 82 is used to guide the carton body 13 into the space between the two abutment surfaces 81. When the carton body 13 moves onto the gluing station 2, the area to be glued of the carton body 13 corresponds to the gluing unit 5. The two conveyor belts 1 stop working, and the driving device 62 drives the two clamping members 61 to approach synchronously in the feeding channel 102 through the synchronous transmission assembly 7, so that a clamping space 9 for clamping the carton body 13 is formed between the two abutment surfaces 81 for subsequent gluing operations. The two clamping members 61 clamp the carton body 13 and position it on the gluing station 2 to prevent the carton body 13 from moving, so that the gluing of the gluing unit 5 is more accurate, and the stability of the gluing operation is ensured.

[0030] During the gluing process, the moving component 4 adjusts the position of the gluing roller 52, and the second translation mechanism 43 drives the gluing roller 52 to translate vertically so that the gluing roller 52 contacts the cardboard at the top of the carton body 13, and the glue outlet 502 of the glue feeding cylinder 53 injects glue onto the gluing roller 52; the first translation mechanism 42 drives the gluing roller 52 to translate horizontally, and the gluing roller 52 rolls on the cardboard to evenly apply the glue on the cardboard.

[0031] Preferably, a controller 10 is provided on the side wall of the gluing table 2, and the moving component 4 and the driving device 62 are connected to and controlled by the controller 10. A sensing device 11 electrically connected to the controller 10 is provided on the mounting plate 51, and a sensing part 12 for sensing by the sensing device 11 is provided on the top of the clamping member 61. The sensing device 11 can be a proximity switch, and the sensing part 12 can be a sensing metal. When the sensing end of the sensing device 11 corresponds to the corresponding sensing part 12, the sensing device 11 triggers a signal, and the controller 10 stops the first translation mechanism 42. With the cooperation of the two sensing parts 12 and the sensing device 11, the controller 10 limits the lateral movement of the gluing roller 52, so that the lateral movement stroke of the gluing roller 52 is adapted to the cardboard to be glued.

[0032] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementation methods. Any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of protection required by the present invention.
