DETAILED DESCRIPTION

[0014] In order to deepen the understanding and recognition of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described and introduced in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments, and are not intended to limit the embodiments in any form. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0015] See also Figure 1-2The utility model provides a technical solution: a top and bottom cover paper box forming machine, including a forming frame 1, an extrusion block 2 is provided in the middle of the forming frame 1, and sliding grooves 3 are provided on the four side walls of the extrusion block 2. An auxiliary plate 4 is slidably connected in the sliding groove 3, and a vacuum suction head 5 is fixedly connected to one side of the auxiliary plate 4. The vacuum suction head 5 is connected to the air pump to form a negative pressure at the vacuum suction head 5, thereby adsorbing and fixing the paper box. A connecting column 6 is fixedly connected to the other side of the auxiliary plate 4. A connecting cavity 8 is provided in the middle of the interior of the extrusion block 2. The top of the connecting column 6 is located in the connecting cavity 8. An extrusion spring 7 is provided between the connecting column 6 and the inner wall of the sliding groove 3. A driving member 10 is fixedly connected to the upper end of the extrusion block 2. The driving member 10 is hollow inside. A driving plate 11 is fixedly connected to the outer wall of the driving member 10. The driving plate 11 is connected to the hydraulic rod to control the driving The part 10 and the driving plate 11 move up and down. A fixed rod 9 is provided inside the driving part 10. The four side walls of the fixed rod 9 are slidably connected with a locking block 12. The four side walls of the fixed rod 9 are slidably connected with a movable plate 20. The lower end of the movable plate 20 is hinged with a rotating rod 21. The lower end of the rotating rod 21 is hinged to the top of the connecting column 6. The upper end of the movable plate 20 is fixedly connected with a control plate 17. One side of the control plate 17 is fixedly connected with a locking protrusion 18, and the other side of the control plate 17 is fixedly connected with a socket head 19. The carton is placed on the forming frame 1. When the extrusion block 2 moves downward, the carton is extruded and formed. After the vacuum suction head 5 adsorbs and fixes the carton, the extrusion block 2 moves upward to remove the formed carton from the forming frame 1, thereby exposing the four sides of the carton to facilitate subsequent information printing.

[0016] A deformation piece 13 is fixedly connected to the inside of the fixing rod 9. The deformation piece 13 is an arc-shaped structure. The deformation piece 13 abuts against the side end of the locking block 12. The deformation piece 13 is an elastic iron sheet. A fixing protrusion 16 is fixedly connected to the inner wall of the driving member 10. The side end of the fixing protrusion 16 is an arc-shaped structure. The upper corner of the locking block 12 is an arc-shaped structure. When the driving member 10 moves downward, the fixed protrusion 16 squeezes the upper end of the locking block 12, thereby pushing the locking block 12 to move. The locking block 12 squeezes the deformation piece 13, causing the deformation piece 13 to deform and store force.

[0017] The side end of the locking block 12 is provided with a locking groove 14, and the side end of the locking protrusion 18 is an arc-shaped structure. Before the extrusion block 2 enters the forming frame 1, the locking protrusion 18 and the locking groove 14 are engaged, and the locking block 12 locks and fixes the locking protrusion 18, thereby limiting and fixing the position of the vacuum suction head 5. When the locking block 12 moves, the locking protrusion 18 disengages from the locking groove 14. Under the action of the extrusion spring 7, the movable plate 20 and the auxiliary plate 4 move, thereby pressing the vacuum suction head 5 against the inner wall of the forming paper box, thereby limiting and fixing the paper box.

[0018] An extrusion head 15 is fixedly connected to the inner wall of the driving member 10. The extrusion head 15 and the socket head 19 are both arc-shaped structures. The extrusion head 15 is located at the lower end of the socket head 19. The driving member 10 continues to move upward, and the extrusion head 15 squeezes the socket head 19, thereby driving the movable plate 20 and the auxiliary plate 4 to move together, detaching the vacuum suction head 5 from the inner wall of the paper box, and continuing to clamp the locking protrusion 18 in the locking groove 14.

[0019] A friction plate is fixedly connected to the interior of the fixed rod 9, and the side end of the movable plate 20 rests on the friction plate to control the moving speed of the movable plate 20 to prevent the vacuum suction head 5 from moving too fast and damaging the paper box due to excessive force when the vacuum suction head 5 hits.

[0020] Although the embodiments of the present invention have been shown and described, it should be emphasized that the above description is merely an introduction and description of the use of the embodiments of the present invention and does not limit the present invention in any form. It will be understood by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
