Description

Technical Field

[0001] The utility model belongs to the technical field of corrugated paper box processing, and in particular relates to a corrugated paper box precision cutting device. Background Art

[0002] Corrugated cardboard is made into corrugated boxes through die-cutting, creasing, nailing or gluing. Corrugated boxes are the most widely used packaging products, and the amount of use has always been the first among various packaging products. Including calcium plastic corrugated boxes, corrugated boxes have gradually replaced wooden boxes and other transportation packaging containers with their superior performance and good processing performance, becoming the main force of transportation packaging. In the processing of corrugated boxes, it is necessary to use a cutting device to cut the corrugated cardboard to the specified specifications to facilitate subsequent production and processing.

[0003] In the existing cutting devices, when cutting and slotting corrugated cardboard boxes, it is necessary to use a pressing mechanism to press and limit the corrugated cardboard boxes to avoid displacement during cutting. However, due to the influence of the material of the corrugated cardboard boxes themselves, if the pressing pressure is too large, it is easy to cause dents on the corrugated cardboard boxes, and if the pressing pressure is too small, displacement will occur. Therefore, the current pressing structures are all implemented by automatic control and programming. Although the problem of excessive or insufficient pressure is solved, the overall fault tolerance rate is low. Once a pressure output failure occurs, all corrugated cardboard boxes in the same batch will be damaged. Therefore, there are great limitations in actual use and there is room for improvement. Utility Model Content

[0004] The purpose of the utility model is to provide a corrugated paper box precision cutting device to solve the problem that the existing cutting device proposed in the above background technology has no protection mechanism and low fault tolerance when pressing the corrugated paper box.

[0007] An adjusting member is arranged in the connection area between the connecting member and the pressure plate, and the movement of the connecting member is realized by the adjusting member. When the pressure of the pressure plate is too large, the pressure can be reduced and transmitted to the corrugated box. When the pressure is insufficient, the adjusting member is slowly forced to adjust by the deadweight of the connecting member and realize the clamping function. The connecting member includes a buffer block, and a connecting column is fixed on the top surface of the buffer block. The connecting column is movably inserted into the interior of the pressure plate and abuts against the adjusting member. A limiting member is also arranged between the pressure plate and the connecting column. The limiting member passes through the pressure plate and the connecting column, and the limiting member ensures that the connecting column will not be separated from the pressure plate.

[0008] Preferably, a through hole is provided on the bottom end surface of the pressure plate for inserting a connecting column, so that the connecting column can be raised and lowered in the through hole. A screw hole connected to the through hole is provided on the bottom rear surface of the pressure plate. The limiting member includes a connecting bolt screwed into the screw hole. The connecting bolt passes through the connecting groove to the interior of the pressure plate, thereby limiting the connecting column.

[0009] Preferably, the adjusting member is a spring placed inside the through hole, and the spring abuts against the end surface of the connecting column. During pressing, the conduction of pressure is reduced by compression of the spring, thereby achieving buffering.

[0010] Preferably, a rubber pad is provided at the bottom of the buffer block, and double-sided tape is bonded between the rubber pad and the buffer block, and a quick connection is achieved through the double-sided tape. In the limitation of the corrugated box, flexible extrusion contact can be achieved through the rubber pad, thereby reducing the risk of the corrugated box being dented.

[0011] Preferably, the cutting assembly includes a column that rises and falls vertically in the middle of the machine body, and a cutter mounted on the column. During cutting, the corrugated box is first limited and pressed by a pressing plate, and then the cutter is driven downward by the column to complete the cutting and / or slotting of the corrugated box.

[0012] Preferably, a transmission box is installed at one end of the body, and a power assembly is arranged inside the transmission box. Since this structure is a prior art, it is not shown in the figure and is not described in detail. The power assembly includes a hydraulic cylinder, which is connected to the column and the pressure plate.

[0013] Preferably, a display screen is also installed on the front surface of the body, and a paper feeding platform is installed at a downward position in the middle of the body. The paper feeding platform is at the bottom of the cutter. During use, the corrugated cardboard box is transferred to the position of the cutter through the paper feeding platform, and the corrugated cardboard box is cut by the cutter.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] Through the designed protective component, a buffer area can be formed between the pressing plate and the corrugated box to avoid dents on the surface of the corrugated box due to excessive pressure. At the same time, it can also realize the function of auxiliary pressing, further preventing the phenomenon of inaccurate cutting caused by insufficient pressure. The overall structure of the protective component is simple, the installation is convenient, and the overall practicality is high, which improves the shortcomings of the existing cutting device in use.
