Abstract
Description
Technical Field
[0001] This utility model relates to the field of cardboard box production technology, and in particular to a creasing and folding device for producing packaging cardboard boxes. Background Technology
[0002] Before producing packaging cartons, a 90-degree transverse crease process is required at corresponding locations (bottom, top, and sides of the carton). Existing crease-pressing equipment for packaging cartons generally includes a workbench and an electric or hydraulic pressure plate. In practice, the carton board is placed on the workbench (which has a limiting seat at the front end to limit the front of the carton board and facilitate the downward pressing operation of the pressure plate). Then, the pressure plate is controlled to descend, pressing the carton board laterally into the "L"-shaped crease groove on the workbench, thus forming a crease at the corresponding location on the carton board. However, current crease-pressing devices require individual operation on each carton, and the crease depth cannot be easily adjusted according to different thicknesses of cartons, thus affecting the efficiency and applicability of the carton crease-pressing operation. Utility Model Content
[0003] The purpose of this invention is to provide a creasing and folding device for producing packaging cartons in order to solve the above-mentioned problems.
[0004] This utility model achieves the above objectives through the following technical solutions:
[0005] A creasing and crease-pressing device for producing packaging cartons includes a pressure-applying mechanism for overall creasing of the cartons, and a support adjustment mechanism for adjusting the creasing depth. The pressure-applying mechanism includes a support assembly, on which the pressure-applying assembly is mounted. The support assembly includes a support platform, with side plates vertically fixed around the upper periphery of the support platform and a placement platform fixed at the upper end of the side plates. The support adjustment mechanism includes a limiting post vertically passing through the placement platform, with a support wheel installed at the lower end of the limiting post. A recessed platform is provided at the center of the upper surface of the support platform, and a slide groove located below the support wheel and communicating with the recessed platform. A wedge block is provided in the slide groove, with a spring at one end of the wedge block away from the center and a push rod fixed at the other end of the wedge block. A central shaft is provided between the support platform and the placement platform, with a cam fixedly mounted on the central shaft and a power assembly connected to the central shaft.
[0006] Further configuration: The pressure application assembly includes a beam frame fixed to the rear side of the placement platform, a cylinder vertically mounted on the beam frame, a pressure plate connected to the lower end of the cylinder, a guide post vertically fixed on the placement platform that passes through the pressure plate, an indentation knife mounted at the lower end of the pressure plate, and a positioning seat mounted on the placement platform.
[0007] Further configuration: The power assembly includes a worm gear fixed on the central shaft, a worm gear meshing with the worm gear on the side plate, a handwheel connected to one end of the worm gear, and the worm gear rotatably connected to the side plate.
[0008] Further configuration: The pressure plate and guide post are slidably connected.
[0009] Further details: The limiting post is slidably connected to the placement platform, and the wedge block is slidably connected to the support platform.
[0010] Further details: The central shaft is rotatably connected to the support platform and the placement platform; the end of the push rod is hemispherical; and the cam is slidably connected to the push rod.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] By setting up a pressure application mechanism and a support adjustment mechanism, when the power component drives the central shaft and cam to rotate, the outer side of the cam pushes the push rod at the end of the wedge block, causing the wedge block to slide in the groove. The upper end of the wedge block pushes the limit post at the upper end of the support wheel to extend upward to a suitable height on the placement platform. When the pressure application component applies downward to the entire carton, it supports and controls the depth of the indentation, making it easier to perform indentation operations on cartons of different specifications and improving work efficiency.

[0023] The present invention will be further described below with reference to the accompanying drawings:
[0024] like Figures 1-5 As shown, a creasing device for producing packaging cartons includes a pressure applying mechanism for creasing the entire carton, and a support adjustment mechanism is provided on the pressure applying mechanism for adjusting the creasing depth.
[0025] In this embodiment: the pressure applying mechanism includes a support assembly, on which the pressure applying component is provided. The support assembly includes a support platform 11, with a side plate 12 vertically fixed around the upper periphery of the support platform 11. A placement platform 13 is fixed at the upper end of the side plate 12. The pressure applying component includes a beam frame 14 fixed to the rear side of the placement platform 13. A cylinder 16 is vertically installed on the beam frame 14. A pressure plate 17 is connected to the lower end of the cylinder 16. A guide post 15 passing through the pressure plate 17 is vertically fixed on the placement platform 13. Two guide posts 15 are arranged opposite each other on one side. The pressure plate 17 is slidably connected to the guide post 15. When the cylinder 16 pushes the pressure plate 17 to move downward under the limit of the guide post 15, the pressure plate 17 contacts the support adjustment mechanism and prevents the creasing knife 18 from moving downward. The creasing knife 18 is installed at the lower end of the pressure plate 17. The installation and adjustment of the creasing knife 18 can be adjusted according to the different specifications of the carton. A positioning seat 19 is installed on the placement platform 13 for positioning the carton on the placement platform 13.
[0026] In this embodiment: the support adjustment mechanism includes a limiting post 21 that passes vertically through the placement platform 13, a support wheel 22 installed at the lower end of the limiting post 21, a recessed platform at the center of the upper surface of the support platform 11, and a sliding groove 101 located below the support wheel 22 and communicating with the recessed platform. A wedge block 23 is provided in the sliding groove 101. The wedge block 23 contacts the support wheel 22 and supports the height of the limiting post 21 extending out of the placement platform 13. A spring 24 is provided at the end of the wedge block 23 away from the center to push the wedge block 23 so that the push rod 25 is always in contact with the cam 27. The other end of the wedge block 23 is fixed with the push rod 25. A central shaft 26 is provided between the support platform 11 and the placement platform 13. A cam 27 is fixedly provided on the central shaft 26. A power component is connected to the central shaft 26.
[0027] The power assembly includes a worm gear 28 fixed on the central shaft 26, a worm 29 meshing with the worm gear 28 on the side plate 12, a handwheel connected to one end of the worm 29, and the worm 29 rotatably connected to the side plate 12; a limiting post 21 slidably connected to the placement platform 13, and a wedge block 23 slidably connected to the support platform 11; the central shaft 26 rotatably connected to the support platform 11 and the placement platform 13; the end of the push rod 25 is hemispherical, and the cam 27 slidably connected to the push rod 25, meshing with the worm gear 28 through the worm 29. The rotation drives the central shaft 26 and cam 27 to rotate. When the cam 27 rotates, its outer side pushes the push rod 25 at the end of the wedge block 23, causing the push rod 25 to push the wedge block 23 to slide in the slide groove 101. At the same time, the wedge block 23 squeezes the spring 24. The upper end of the wedge block 23 pushes the limiting post 21 at the upper end of the support wheel 22 to extend upward to a suitable height on the placement platform 13. This allows the limiting post 21 to limit the pressure plate 17 when the creasing knife 18 creasing the carton downward, thus controlling the creasing depth of the creasing knife 18.
[0028] The working principle and usage process of this utility model are as follows: Place the carton on the placement platform 13 and align it with the positioning seat 19. Adjust the required indentation depth according to the thickness of the carton. By rotating the worm gear 29, the worm gear 29 meshes with the worm wheel 28 and rotates, driving the central shaft 26 and the cam 27 to rotate. When the cam 27 rotates, its outer side pushes the push rod 25 at the end of the wedge block 23, causing the push rod 25 to push the wedge block 23 to slide in the slide groove 101. At the same time, the wedge block 23 squeezes the spring 24. The upper end of the wedge block 23 pushes the limiting post 21 at the upper end of the support wheel 22 to extend upward to a suitable height on the placement platform 13. Then, when the cylinder 16 pushes the pressure plate 17 to move downward under the limit of the guide post 15, the pressure plate 17 contacts the limiting post 21 and limits the downward movement of the pressure plate 17. The indentation depth of the indentation knife 18 on the carton is exactly the indentation requirement of the carton, so as to meet the indentation adjustment needs of cartons of different thicknesses.
[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
