DETAILED DESCRIPTION

[0016] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0017] like Figure 1-4As shown, a hot melt adhesive spraying device for carton molding includes a workbench 1, the upper surface of the workbench 1 includes a placement area and an installation area, the placement area is used to place cardboard 22, a lifting part is arranged on the installation area, a guide rod 2 is arranged on the upper surface of the installation area, a mounting plate 3 is slidably connected to the guide rod 2, a hydraulic cylinder 4 is arranged at the lower part of the workbench 1, the output end of the hydraulic cylinder 4 is fixedly connected to the lower surface of the mounting plate 3, a ball screw assembly is arranged on the upper surface of the mounting plate 3, the ball screw assembly is driven by a motor 6, the ball screw assembly has a mounting block 7 that can move linearly, slide rods 8 are arranged on both sides of the mounting block 7, a support block 9 is arranged at one end of the slide rod 8 away from the mounting block 7, and the support block 9 is slidably connected to the mounting plate 3, a moving block 10 is slidably connected to the slide bar 8, a push plate 11 is slidably connected to the lower surface of the moving block 10, the push plate 11 is located on the upper surface of the mounting plate 3, a limit frame 12 is arranged on the upper surface of the push plate 11, a through groove is provided inside the limit frame 12, and also includes a limit bolt 13 for fixing the limit frame 12 and the moving block 10 to the slide bar 8, an extension plate 14 is arranged on the upper end of the guide rod 2, a glue applicator 15 is arranged on the extension plate 14, side plates 16 are arranged on both sides of the mounting plate 3, baffles 17 are slidably connected to the two side plates 16, the baffles 17 are fixed to the side plates 16 by positioning bolts 18, and a rotatable material guide plate 19 is arranged between the two baffles 17.

[0018] The placement area is used to place cardboards 22 that are stacked together and have completed die-cutting. A placement table 21 is set on the upper surface of the placement area. The height of the placement table 21 is greater than the thickness of the side panel 16, and the thickness of the baffle 17 is not greater than the thickness of the cardboard 22. When only one cardboard 22 is left on the placement table 21, the upper surface of the mounting plate 3, the upper surface of the side panel 16 and the upper surface of the baffle 17 are all lower than the upper surface of the placement table 21. The only cardboard 22 left on the placement table 21 can be pushed from the placement table 21 to the position of the guide plate 19 by the push plate 11.

[0019] Under the action of the hydraulic cylinder 4, the push plate 11 can push the cardboard 22 from the placement table 21 to the guide plate 19 layer by layer from top to bottom, and the baffle 17 can block the second highest cardboard 22, thereby preventing the upper cardboard 22 from driving the lower cardboard 22 to move when the uppermost cardboard 22 is pushed out by the push plate 11.

[0020] Since the outer edge of the cardboard 22 is not neat after die-cutting, it is easy to push the cardboard 22 crooked when it is pushed from the placement table 21 to the guide plate 19 by the push plate 11. Therefore, the moving blocks 10 on the two slide bars 8 can be controlled to move respectively, and the two moving blocks 10 can be moved to positions close to the edges of the cardboard 22 respectively. At this time, the distance between the two moving blocks 10 is slightly smaller than the length of the cardboard 22 after unfolding. Then, the positions of the push plates 11 on the moving blocks 10 are adjusted respectively, so that one end of the push plates 11 abuts against one end of the cardboard 22. When one end of the two push plates 11 abuts against the cardboard 22, the limit frame 12 is fixed to the moving block 10 by the limit bolt 13, and the moving block 10 is fixed to the slide bar 8 at the same time. Therefore, the cooperation of the motor 6 and the ball screw assembly 5 can drive the mounting block 7 to move, and the push plates 11 on both sides can be driven to move by the mounting block 7. The two push plates 11 push the cardboard 22 at the same time, and push the cardboard 22 onto the guide plate 19.

[0021] Due to the different specifications of the cardboard 22, in order to enable the baffle 17 to accurately block the movement of the cardboard 22 at the second height, the sliding of the baffle 17 on the side plate 16 is controlled. When one side of the baffle 17 abuts against the cardboard 22, the baffle 17 is fixed to the side plate 16 by the positioning bolt 18, thereby preventing the cardboard 22 at the second height from moving with the cardboard 22 at the top layer when the cardboard 22 at the top layer is pushed.

[0022] A conveyor belt 20 is provided on one side of the workbench 1. The lower end of the guide plate 19 is inclined toward the conveyor belt 20. When a rated number of cardboards 22 are placed on the placement table 21, the inclination angle of the guide plate 19 is as follows: Figure 4 As shown, in this case, due to the obstruction of the side plate 16, the guide plate 19 cannot continue to flip clockwise, preventing the angle between the guide plate 19 and the conveyor belt 20 from approaching or being equal to 90°. The smaller the angle between the guide plate 19 and the conveyor belt 20, the more stable the sliding of the cardboard 22 on the guide plate 19. Under the action of the hydraulic cylinder 4, when the guide plate 19 moves downward following the side plate 16 and the mounting plate 3, when the lower end of the guide plate 19 contacts the conveyor belt 20, and as the mounting plate 3 continues to descend, the angle between the guide plate 19 and the conveyor belt 20 will continue to decrease, and the horizontal height of the upper end of the guide plate 19 is always lower than the horizontal height of the lower surface of the cardboard 22 located at the top layer, so that the cardboard 22 can be stably pushed onto the guide plate 19.

[0023] The hot melt adhesive in a molten state is transported to the glue applicator 15 through the feed pipe, and is sprayed onto a predetermined position of the cardboard 22 by the glue applicator 15. In the process of pushing the cardboard 22 from the placement table 21 to the guide plate 19 by the push plate 11, the glue applicator 15 works synchronously. When the gluing work of a single cardboard 22 is completed, the glue applicator 15 stops spraying glue. After the push plate 11 pushes the cardboard 22 onto the guide plate 19, the push plate 11 returns to its initial position under the action of the ball screw assembly 5 and the motor 6, and the hydraulic cylinder 4 drives the mounting plate 3 to descend a certain height, and the descending height is the same as the thickness of the cardboard 22, so that the cardboard 22 on the uppermost layer can be continuously pushed from the placement table 21 to the guide plate 19.

[0024] Furthermore, after the cardboard 22 is placed on the placement table 21 , the cardboard 22 can completely cover the upper surface of the placement table 21 , preventing the placement table 21 from hindering the descent of the side panels 16 , the baffles 17 and the mounting plate 3 .

[0025] Furthermore, a washer 23 is provided between the limiting bolt 13 and the limiting frame 12 . The washer 23 is made of rubber or metal and can reduce the friction between the limiting bolt 13 and the limiting frame 12 , thereby protecting the limiting frame 12 .

[0026] Working principle: When in use, the stacked cardboards 22 are placed on the placement table 21, and then the position of the push plate 11 is adjusted so that the two push plates 11 can abut against the outer surface of the cardboard 22, and the position of the two baffles 17 is adjusted so that the two baffles 17 can abut against the outer surface of the cardboard 22 at the second height, and then the motor 6 drives the mounting block 7 on the ball screw assembly 5 to move, and the mounting block 7 drives the two push plates 11 to move, and the cardboard 22 located on the top layer is pushed from the placement table 21 to the guide plate 19, and in the process of pushing, the glue applicator 15 sprays hot melt glue on the predetermined position of the cardboard 22. After the gluing of the cardboard 22 is completed, the direction of the push plate 11 is controlled by the motor 6 and the ball screw assembly 5, and then the mounting plate 3 is controlled by the hydraulic cylinder 4 to move downward by the height of a cardboard 22, so as to facilitate the pushing out and gluing of the next cardboard 22. The staff are located on both sides of the conveyor belt 20 and fold the glued cardboard 22 into cartons.

[0027] The device can glue the cardboard 22 while pushing it out. The staff only needs to place the stacked cardboard 22 on the workbench 1, and there is no need to take the glued cardboard 22 out of the placement table 21 separately, which saves time and improves the processing efficiency of the carton.
