Description

Technical Field

[0001] This utility model belongs to the field of packaging box technology, and in particular relates to a cardboard cutting device for packaging box processing. Background Technology

[0002] Packaging boxes are containers used to protect, store, transport, or display products. They are typically made of cardboard, wood, plastic, metal, or composite materials. They are an indispensable tool in modern logistics and supply chains, designed to ensure that products are protected from damage during transportation, warehousing, and other processes, while also enhancing brand image and user experience.

[0003] During the processing of packaging boxes, cardboard needs to be cut. The problem with the above technology is that in the existing technology, when traditional cutting devices cut cardboard, the cutting blade needs to be replaced after long-term use. The cutting blade is generally fixed by bolts, and the replacement process is relatively cumbersome. Utility Model Content

The bottom of the mounting frame is fixedly installed on the rear side of the top of the base, the top of the support legs is fixedly installed on the bottom of the base, a support frame is installed on the top of the base, a moving mechanism is installed on the top of the base, a positioning mechanism is installed on the top of the base, a cutting mechanism is installed on the top of the mounting frame, a fixing mechanism is installed on the bottom of the mounting frame, and a buffer spring is installed on the top of the mounting frame.

[0006] To improve the movement of the positioning mechanism, preferably, the moving mechanism includes a servo motor, a lead screw, a support plate, and a threaded plate. The bottom of the support plate is fixedly installed on the top of the base. The right side of the lead screw is movably connected to the left side of the right support plate via a rotating shaft. The surface of the lead screw is movably installed on the middle of the left support plate. The output end of the servo motor is fixedly installed on the left side of the lead screw. The bottom of the servo motor is fixedly installed on the top of the base. The middle of the threaded plate is movably installed on the surface of the support frame. The middle of the threaded plate is movably installed on the surface of the lead screw. The surface of the lead screw and the middle of the threaded plate are connected by a thread. The servo motor can rotate, driving the lead screw to rotate. The lead screw, through the threaded connection, drives the threaded plate to move, and the threaded plate drives the positioning mechanism to move.

[0007] To facilitate the fixing of the cardboard, preferably, the positioning mechanism includes a positioning frame, a positioning plate, and a hydraulic rod. The bottom of the positioning frame is fixedly installed on the top of the threaded plate, the middle part of the positioning plate is movably installed on the surface of the positioning frame, the bottom of the hydraulic rod is fixedly installed on the top of the positioning frame, and the output end of the hydraulic rod is fixedly installed on the top of the positioning plate. The positioning plate can be moved by the hydraulic rod, and the positioning plate fixes the cardboard.

[0008] To facilitate the cutting of cardboard, the cutting mechanism preferably includes a second hydraulic rod, a fixed frame, a mounting slot, and a cutting blade. The bottom of the second hydraulic rod is fixedly mounted to the top of the mounting frame, the surface of the fixed frame is movably mounted to the surface of the mounting frame, the output end of the second hydraulic rod is fixedly mounted to the top of the fixed frame, the top of the mounting slot is fixedly mounted to the bottom of the fixed frame, and the surface of the cutting blade is movably mounted to the inner wall of the mounting slot. The cutting mechanism can be driven by the second hydraulic rod, which moves the fixed frame, which in turn moves the mounting slot, which in turn moves the cutting blade, thus cutting the cardboard.

[0009] To facilitate the replacement of the cutting blade, preferably, the fixing mechanism includes a fixing rod, a fixing ring, and a fixing spring. The left side of the fixing ring is fixedly installed on the right side of the mounting groove. The surface of the fixing rod is movably installed on the middle of the fixing ring and the surface of the fixing rod is movably installed on the middle of the cutting blade. One end of the fixing spring is fixedly installed on the right side of the fixing ring, and the other end of the fixing spring is fixedly installed on the right side of the fixing rod. The fixing spring is sleeved on the surface of the fixing rod. By moving the fixing rod, the fixing rod can be separated from the cutting blade, thereby allowing the cutting blade to be replaced.

[0010] To improve the cushioning effect on the mounting frame, preferably, one end of the cushioning spring is fixedly installed on the top of the mounting frame, and the other end of the cushioning spring is fixedly installed on the top of the mounting frame. The cushioning spring is sleeved on the surface of the mounting frame and can be installed on the mounting frame to cushion the mounting frame.

[0011] To facilitate the movement of the fixing rod, preferably, a pull plate is installed on the right side of the fixing rod, which can move the fixing rod by moving the pull plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This utility model, by setting up a base, legs, mounting frame, support frame, moving mechanism, positioning mechanism, cutting mechanism, fixing mechanism, and buffer spring, firstly mounts the cardboard onto the threaded plate. Then, the positioning mechanism is opened, and hydraulic rod one is driven, which moves the positioning plate and fixes the cardboard. Next, the moving mechanism is opened, and the servo motor rotates, which drives the lead screw to rotate. The lead screw moves the threaded plate, which moves and adjusts the cardboard. Then, the cutting mechanism is opened, and hydraulic rod two is driven, which moves the cutting blade and cuts the cardboard. When the cutting blade needs to be replaced, the pull plate is pulled, which moves the fixing rod, separating the fixing rod from the cutting blade, thus facilitating the replacement of the cutting blade. This solves the problem in existing technologies where, when cutting cardboard, the cutting blade needs to be replaced after long-term use, and the cutting blade is usually fixed with bolts, making the replacement process cumbersome.
