DETAILED DESCRIPTION

[0018] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0019] The present application embodiment discloses a waste material removal device for a printing and packaging machine. Figure 1 The waste material removal device for printing and packaging machinery may include a cutting table 10, a cutting hydraulic cylinder 20, a positioning cutting piece 30 and two sets of limiting modules 40. The cutting hydraulic cylinder 20 is installed and fixed on the top of the cutting table 10, and the output end of the cutting hydraulic cylinder 20 is connected to the positioning cutting piece 30, so that the cutting hydraulic cylinder 20 drives the movement of the positioning cutting piece 30 to complete the fixing and cutting of the packaged product. The two sets of limiting modules 40 are symmetrically arranged on the opposite sides of the introduction conveyor belt 14 in the cutting table 10, and the limiting modules 40 have a movable part that moves along the width direction of the limiting modules 40, and the packaged product is centrally transported to the position directly below the positioning cutting piece 30 under the limitation of the two sets of movable parts.

[0020] See also Figure 2The cutting table 10 may include a table body 11, a bracket 13, an inlet conveyor belt 14 and an outlet conveyor belt 15. The bracket 13 is fixedly connected to the top of the table body 11, and an opening is formed at the lower end of the bracket 13. The top of the bracket 13 can support and install the cutting hydraulic cylinder 20, and the packaged product can be moved in or out through the opening on the bracket 13. The inlet conveyor belt 14 and the outlet conveyor belt 15 are both installed on the inner side of the table body 11, and the inlet conveyor belt 14 and the outlet conveyor belt 15 are located on opposite sides of the cutting groove 12. The tops of the inlet conveyor belt 14 and the outlet conveyor belt 15 are aligned with the top plane of the table body 11, so that the packaged product can be transported to or from the bottom of the positioning cutting piece 30. A cutting groove 12 is formed on the table body 11, and the cutting groove 12 is located directly below the cutting knife 35 and cooperates with it, so that when the positioning cutting piece 30 moves downward, it can cooperate with the cutting groove 12 to complete the removal of the waste edge of the packaged product.

[0021] See also Figure 3 The positioning and cutting member 30 comprises a press platform 31, at least two groups of positioning posts 32, springs 33 equal in number to the number of positioning posts 32, a sliding plate 34, a cutting knife 35 and a knife groove 36. At least two groups of positioning posts 32 are fixed on the bottom inner wall of the press platform 31, and a group of springs 33 are sleeved on the outer side of each group of positioning posts 32, and the two ends of the springs 33 are respectively fixedly connected to the bottom inner wall of the press platform 31 and the sliding plate 34. The cutting knife 35 is fixedly connected to the bottom of the sliding plate 34, and the knife groove 36 is formed on the bottom inner wall of the press platform 31, and the cutting knife 35 can move through the knife groove 36 and extend into the cutting groove 12. The output end of the cutting hydraulic cylinder 20 extends into the press table 31 and is connected to the sliding plate 34, so that when the cutting hydraulic cylinder 20 drives the sliding plate 34 to push downward, the positioning cutting piece 30 as a whole can move downward at the same time; after the press table 31 presses the product on the table body 11, the output end of the cutting hydraulic cylinder 20 continues to push the sliding plate 34 downward, so that it can compress the spring 33, and the cutting knife 35 passes through the knife groove 36 to complete the removal of the waste edge of the product. After the cutting is completed, when the output end of the cutting hydraulic cylinder 20 drives the sliding plate 34 to move upward, the sliding plate 34 can be reset first, and then the positioning cutting piece 30 can move upward as a whole. The height of the press table 31 is less than the height of the bracket 13, so that the press table 31 can move inside the bracket 13.

[0022] See also Figure 4The limit module 40 includes a mounting frame 41, a positioning hydraulic cylinder 42, an adjustment arm 43, a double-linked frame 44, a sliding arm 45 and a limit plate 46. The mounting frame 41 is fixedly mounted on the side wall of the platform 11, and the positioning hydraulic cylinder 42 is supported and mounted on the top of the mounting frame 41. The output end of the positioning hydraulic cylinder 42 is rotatably connected to the top of the adjustment arm 43, and the middle part of the adjustment arm 43 is rotatably connected to the mounting frame 41, so that when the output end of the positioning hydraulic cylinder 42 moves, the adjustment arm 43 can be pushed to deflect with the connection position between the adjustment arm 43 and the mounting frame 41 as the rotation center. The bottom end of the adjustment arm 43 is rotatably connected to the adjacent end of the double-linked frame 44, and the other end of the double-linked frame 44 is rotatably connected to the sliding arm 45. A slide groove with a width matching the width of the sliding arm 45 is formed in the middle part of the mounting frame 41, and the sliding arm 45 moves through the slide groove, so that when the adjustment arm 43 deflects, the double-linked frame 44 can be used to push the sliding arm 45 to move laterally under the guidance of the slide groove. The limit plate 46 is fixedly connected to the side of the sliding arm 45 facing the inlet conveyor belt 14. The conveying limit plate 46 constitutes the movable part of the limit module 40. After the limit plates 46 of the two groups of limit modules 40 are moved until the distance between them is adapted to the width of the packaged product, the product can be centered when it is transported using the inlet conveyor belt 14.

[0023] The system of the present invention may also include a control system for controlling the operation of the hydraulic cylinder and the conveyor belt to automatically perform the transport, positioning and cutting of the packaged product. It should be understood that the control system has no particular limitation and can be implemented by the control technology under the prior art, which will not be described in detail here.

[0024] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
