Description
Technical Field
[0001] The utility model relates to the technical field of carton printing and forming, in particular to a movable cutting knife structure for the slotting part of a carton printing and forming production line. Background Technique
[0002] Cartons are the most widely used packaging products. According to different materials, there are corrugated cartons, single-layer cardboard boxes, etc., with various specifications and models. Usually, during the carton printing and forming process, a printing machine is required to print on the carton. After printing, the carton needs to be folded. Before the folding process, the cardboard is extruded by a slotting unit according to production requirements to generate folding marks, so that it is more convenient and error-free to perform the folding component in the subsequent process.
[0003] However, in the high-speed operation process of the existing carton printing and forming, such as paper feeding, printing, slotting, die cutting, etc., when the cardboard is slotted, the waste edges of the cardboard cannot be effectively cut off, freely dropped, and the trimming is smooth, which is not convenient for accurate paper feeding and reduces the work quality and production efficiency. Content of the Utility Model
[0004] The purpose of the utility model is to provide a movable cutting knife structure for the slotting part of a carton printing and forming production line to solve the problems raised in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical scheme: A movable cutting knife structure for the slotting part of a carton printing and forming production line, including a cutting knife seat and a self-lubricating sleeve installed on a spline shaft, and the cutting knife seat is located above the self-lubricating sleeve;
[0006] A plurality of knife seat blocks are annularly and evenly installed on the cutting knife seat, and corner cutting blades are installed on the knife seat blocks. A lower cutting knife wheel is sleeved on the self-lubricating sleeve, and a cardboard is arranged between the lower cutting knife wheel and the cutting knife seat.
[0007] Preferably, a plurality of installation grooves are annularly and evenly opened on the cutting knife seat, and the knife seat blocks are installed in the installation grooves.
[0008] Preferably, the corner cutting blades are clamped into the grooves of the knife seat blocks and are locked and fixed by pressing plate one screws.
[0009] Preferably, the lower cutting knife wheel is fixed on the self-lubricating sleeve by a pressing plate two.
[0010] Preferably, an inverted T-shaped groove is opened on the knife seat block, and the corner cutting blade is of an inverted T-shaped structure, and the corner cutting blade is adapted to the inverted T-shaped groove.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] Ensure effective truncation, free fall, and smooth trimming of the waste edges of the cardboard during slotting. The structure of the movable truncation knife is convenient to disassemble, so as to achieve accurate paper feeding, fast printing speed, good slotting quality, save costs to the greatest extent, and improve work quality and production efficiency. Description of the Drawings
[0013] Figure 1 It is a schematic structural diagram of the present utility model;
[0014] Figure 2 It is a schematic structural diagram of the use of the present utility model.
[0015] In the figure: 1, truncation knife seat; 2, knife seat block; 3, corner blade; 4, pressing plate one; 5, lower truncation knife wheel; 6, self-lubricating sleeve; 7, pressing plate two; 8, cardboard. Detailed Implementation Manner
[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0017] Please refer to Figure 1-2 , the present utility model provides a technical solution: a movable truncation knife structure for the slotting part of a carton printing and forming production line, including a truncation knife seat 1 and a self-lubricating sleeve 6 installed on a spline shaft, and the truncation knife seat 1 is located above the self-lubricating sleeve 6;
[0018] A plurality of knife seat blocks 2 are annularly and evenly installed on the truncation knife seat 1, and a corner blade 3 is installed on the knife seat block 2. A lower truncation knife wheel 5 is sleeved on the self-lubricating sleeve 6, and a cardboard 8 is arranged between the lower truncation knife wheel 5 and the truncation knife seat 1, which solves the problems of effective truncation, free fall, and smooth truncation of the waste edges of the cardboard, and can extend the service life of the lower wheel and improve production efficiency. This structure achieves the purpose of the present invention.
[0019] In the present utility model, a plurality of installation grooves are annularly and evenly formed on the truncation knife seat 1, and the knife seat blocks 2 are installed in the installation grooves.
[0020] In the present utility model, the corner blade 3 is clamped into the groove of the knife seat block 2 and is locked and fixed by screws of the pressing plate one 4, which is convenient for the installation and disassembly of the corner blade 3.
[0021] In the present utility model, the lower truncation knife wheel 5 is fixed on the self-lubricating sleeve 6 through the pressing plate two 7, so that the lower truncation knife wheel 5 is movable and can always rotate.
