Description

Technical Field

[0001] The utility model belongs to the technical field of paperboard creasing, and in particular relates to a corrugated paperboard creasing mechanism with an automatic switching pressing wheel. Background Art

[0002] In the process of color printing and packaging, creasing the cardboard is a key process step. The different folding positions of the cartons directly affect the process flow and steps of the entire creasing process. During processing, a creasing machine is generally used for creasing. The creasing machine is divided into manual creasing machine and automatic creasing machine. The packaging industry mainly uses creasing machines with relatively low requirements and low output force. It can achieve creasing on the cardboard, and then fold the cardboard into a packaging box through the creases to complete the processing of the paper box.

[0003] After searching, the patent announcement number CN220129643U discloses a pressing wheel replacement device for a cardboard creasing machine, including: a base, on which two mounting plates are symmetrically arranged; further including: a rotating shaft, which is arranged between the two mounting plates, including a mounting section and a disassembly section; a mounting device, which is arranged on the rotating shaft and is used to connect the mounting section and the disassembly section; wherein, the mounting section is provided with a plurality of creasing wheels, and the mounting plate is provided with a mounting hole adapted to the disassembly section. The beneficial effect of the present application is that when replacing the creasing wheel, it is only necessary to separate the fixing sleeve from the disassembly section, and then separate the mounting boss from the Anzu groove, so that the mounting section can be separated from the disassembly section, thereby disassembling the creasing wheel on the mounting section, and installing it after replacement, it is only necessary to align the mounting boss with the mounting groove, and then install the fixing sleeve with the disassembly section, and the whole process is quick and convenient.

[0004] In actual use, the existing cardboard creasing machine needs to replace the creasing wheel when different indentations are made on the cardboard. However, the staff's replacement of the creasing wheel is currently inefficient and cumbersome. Therefore, we propose a corrugated cardboard creasing mechanism with automatic switching of the creasing wheel to solve the existing problem. Utility Model Content

[0009] Furthermore, the external thread on the outer wall of the threaded rod and the threaded hole on the end wall of the sleeve are threadedly engaged with each other.

[0010] Furthermore, there is a gap connection between the outer wall of the connecting column and the hole wall of the through hole.

[0011] Furthermore, the outer wall of the positioning column is connected with the hole wall of the first positioning hole and the hole wall of the second positioning hole through a gap.

[0012] Furthermore, the first positioning holes are formed on both sides of the outer walls at both ends of the threaded rod, and the second positioning holes are formed on the surface of the first connecting plate.

[0013] Furthermore, L-shaped fixing ears are installed on both sides of the upper surface of the first mounting plate, and fixing holes are opened at the tops of the L-shaped fixing ears.

[0014] Furthermore, a spring is sleeved on the outer side of the outer wall of the connecting column, and the spring is located between the third connecting plate and the fifth connecting plate.

[0015] By means of the above technical solution, the utility model provides a corrugated cardboard creasing mechanism with automatic switching of pressing wheels, which has at least the following beneficial effects:

[0016] 1. The utility model is provided with a series of coordinated structures. When the staff needs to replace the creasing wheel, the staff starts the hydraulic telescopic rod. The extension of the hydraulic telescopic rod will indirectly drive the creasing wheel to move in the Y-axis direction. After the staff separates the creasing wheel from the cardboard to be creasing, the staff starts the reduction motor. The start of the reduction motor will indirectly drive the roller to rotate. After the roller rotates a certain angle, the replacement of different creasing wheels can be completed. Therefore, the utility model can quickly and automatically replace the creasing wheel. Through the setting of the hydraulic telescopic rod, it is convenient for the staff to adjust the force between the creasing wheel and the cardboard, so that different depths of indentations can be pressed on the cardboard, and it is also convenient to indent cardboards with different thicknesses.

[0017] 2. The utility model is provided by the coordination of a series of structures such as a sleeve, a threaded hole, and a threaded rod. When the staff needs to adjust the spacing between adjacent creasing wheels, the staff rotates the sleeve. Since the external thread on the outer wall of the threaded rod and the threaded hole on the end wall of the sleeve are threadedly engaged, the sleeve can be rotated to move on the threaded rod. The sleeve moves on the threaded rod to adjust the spacing between adjacent creasing wheels, which is convenient for the staff to use.

[0018] 3. The utility model is equipped with a series of structures such as a connecting column, a pulling rod, a spring, a positioning column, a first positioning hole, and a second positioning hole. When the staff needs to disassemble and assemble the threaded rod or the indentation wheel, the staff pulls the pulling rod and moves the positioning column out of the first positioning hole to disassemble and assemble the threaded rod. After the threaded rod is disassembled and assembled, the staff rotates the sleeve and moves the sleeve out of the threaded rod to complete the disassembly and assembly of the indentation wheel. Therefore, the utility model is convenient for the staff to disassemble, assemble, and replace the indentation wheel, and is highly practical. BRIEF DESCRIPTION OF THE DRAWINGS
