DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] The utility model provides a technical solution: Figures 1 to 4 As shown, in the present embodiment, a gluing structure for an automatic paper box forming machine comprises a base 1, a conveyor belt 2 is installed on the top of the base 1, a clamping plate 3 is symmetrically slidably installed in the middle of the base 1, and the two clamping plates 3 can move simultaneously to fix the paper box, a fixing frame 4 is fixedly installed on the top of one end of the base 1, a rotating rod 5 is installed on the top of the fixing frame 4, the rotating rod 5 is inclined, and the rotating rod 5 can be raised and lowered, a mounting frame 6 is fixedly installed on the bottom end of the rotating rod 5, a gluing roller 7 is rotatably installed in the middle of the mounting frame 6, a gluing outlet for gluing is opened on the gluing roller 7, two ends of the gluing roller 7 are arranged through the two ends of the mounting frame 6, and the gluing roller 7 can move as the rotating rod 5 descends.

[0022] like Figures 1 to 4 As shown, a glue bucket 8 for storing colloid is fixedly installed on the top of the fixed frame 4, a pump body 9 is installed on the bottom end of the glue bucket 8, and a connecting hose 10 is fixedly installed on the discharge end of the pump body 9. The end of the connecting hose 10 away from the pump body 9 is rotatably connected to the two ends of the glue coating roller 7 through a sealed bearing.

[0023] The glue in the glue barrel 8 is transported to the inside of the glue coating roller 7 through the pump body 9 and the connecting hose 10, and flows out from the glue outlet on the glue coating roller 7, thereby realizing the gluing operation on the paper box.

[0024] like Figures 1 to 4 As shown, a motor 11 is fixedly installed in the middle of the base 1, an elliptical block 12 is fixedly installed at the output end of the motor 11, an elliptical groove 13 is provided on the upper surface of the elliptical block 12, limiting holes 14 are symmetrically provided on both sides of the base 1, limiting rods 15 are slidably installed inside the limiting holes 14, one end between the two limiting rods 15 is fixedly connected to the splint 3, and the other end between the two limiting rods 15 is fixedly connected to a positioning rod 16, and the positioning rod 16 is slidably connected to the elliptical groove 13.

[0025] The elliptical block 12 is driven to rotate by the motor 11, and the positioning rod 16 will slide inside the elliptical groove 13. As the elliptical block 12 rotates, the elliptical groove 13 will pull the positioning rod 16, which will drive the limiting rod 15 to slide inside the limiting hole 14, and at this time, the two clamping plates 3 will be driven to squeeze and position the carton to fix the position of the carton. After the carton is glued, the elliptical block 12 is then rotated, and the elliptical groove 13 will push the positioning rod 16, which will drive the two clamping plates 3 to move away from each other, and the carton will be transported by the conveyor belt 2 to achieve the next step of forming the carton.

[0026] like Figures 1 to 4 As shown, a lifting frame 17 is fixedly installed on the top of the fixed frame 4, a connecting block 18 is rotatably installed on the top of the rotating rod 5 through an axle pin, and a screw lifting structure 19 for driving the connecting block 18 to rise and fall is installed on the lifting frame 17.

[0027] The connecting block 18 is driven down through the screw lifting structure 19, which in turn drives the rotating rod 5 to rotate and descend. At this time, the glue coating roller 7 installed at the bottom end of the rotating rod 5 will move along the surface of the paper box.

[0028] like Figures 1 to 4 As shown, a squeezing rod 20 for squeezing the rotating rod 5 to change the tilt angle is fixedly installed on one side of the fixing frame 4 at a position corresponding to the rotating rod 5 .

[0029] The tilting position of the rotating rod 5 can be positioned, and when the top of the rotating rod 5 descends, the rotating rod 5 can also be driven to rotate under the squeezing of the squeezing rod 20 on the rotating rod 5.

[0030] like Figures 1 to 4 As shown, a return spring 21 is fixedly installed between the outer side of the extrusion rod 20 and the bottom end of the rotating rod 5 .

[0031] When the glue coating roller 7 installed at the bottom end of the rotating rod 5 moves along the surface of the paper box, the return spring 21 is in an extended state. After the glue coating is completed, the top of the rotating rod 5 is driven to rise through the screw lifting structure 19, and the return spring 21 pulls the bottom end of the rotating rod 5 to assist in driving the rotating rod 5 to return to its initial position.

[0032] The utility model provides a gluing structure for an automatic paper box forming machine, and the specific working principle is as follows:

[0033] When the device is in use, the carton is transported to the designated position through the conveyor belt 2, and the elliptical block 12 is driven to rotate by the motor 11, and the positioning rod 16 will slide inside the elliptical groove 13. As the elliptical block 12 rotates, the elliptical groove 13 will pull the positioning rod 16, and at this time, the limiting rod 15 will be driven to slide inside the limiting hole 14, and at this time, the two clamping plates 3 will be driven to squeeze and position the carton, so as to fix the position of the carton. After the gluing of the carton is completed, the elliptical block 12 is then rotated, and the elliptical groove 13 will push the positioning rod 16, which will drive the two clamping plates 3 to move away from each other, and the carton is then transported by the conveyor belt 2, so as to realize the next step of forming the carton;

[0034] When gluing the carton, the carton is transported to the bottom of the gluing roller 7, and the connecting block 18 is driven down by the screw lifting structure 19, which in turn drives the rotating rod 5 to rotate and descend. At this time, the gluing roller 7 installed at the bottom end of the rotating rod 5 will move along the surface of the carton. In this process, the glue in the glue barrel 8 is transported to the inside of the gluing roller 7 through the connecting hose 10 by the pump body 9, and flows out from the glue outlet on the gluing roller 7 to realize the gluing operation on the carton.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
