In the carton production process, edge cutting is a key process. The purpose of edge cutting is to accurately cut the large size paperboard produced according to the predetermined size, to ensure that the size of the carton meets the standard requirements, so that the carton can adapt to the packaging needs of different products, and the carton with neat edges is also more convenient for subsequent folding, assembling and other operations.

[0003] However, the existing carton edge cutting device on the market has some shortcomings. The structure design is relatively simple and not rich, and most of them only focus on the cutting function itself. The most prominent problem is that there is no special cleaning component. During production and transportation, dust, paper scraps and other particulate impurities are easily attached to the surface of the carton. Without prior cleaning, edge cutting is directly performed. These impurities will produce intense friction with the cutting blade during the cutting action, which will greatly increase the risk of damage to the cutting blade over time. Not only does it reduce the service life of the cutting blade, but frequent replacement of the cutting blade also increases production costs and affects production efficiency. UTILITY MODEL CONTENTS

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0024] With reference to Figures 1-5 The overall structure of the device is designed ingeniously, and the components work in cooperation, aiming to provide a precise, stable and environmentally friendly solution for carton edge cutting operation.

[0025] First, focus on the basic framework of the device. The bottom plate 1 serves as the bearing cornerstone of the entire device, and the placing groove 2 is carefully designed on it. The placing groove 2 is not randomly structured. Its size is closely adapted to the bottom profile of common cartons, which can ensure that the paperboard 3 to be processed is stably fixed in place during the cutting process, effectively avoiding cutting error caused by displacement of the paperboard 3.

[0026] The support frame 4 standing on the bottom plate 1 acts as a key support and structure building role like a loyal guardian. It is made of steel structure welding and has the characteristics of firmness and durability, ensuring that the structure remains stable under long-term and high-intensity work load. A screw rod 8 is erected on the support frame 4 through the carefully designed stabilizing frame 9. This screw rod 8 is the core component of the entire vertical lifting power transmission.

[0027] Regarding the power mechanism, the device selects the driving motor 7 installed on the support frame 4. This driving motor 7 is not an ordinary motor. It is a high-performance motor with precisely matched power according to the common edge cutting frequency and load requirements of the carton processing industry. The output shaft of the driving motor 7 is tightly and rigidly connected with the end of the screw rod 8. When the driving motor 7 is powered on and operates, it can accurately and stably drive the screw rod 8 to rotate, providing continuous vertical lifting power for the subsequent edge cutting action.

[0028] In order to ensure the lifting movement of the lifting frame 10 on the screw rod 8 is accurate and smooth, a limiting mechanism is specially equipped. The limiting rod 6 installed on the lifting frame 10 is made of high-precision cylindrical stainless steel material, and the surface is finely polished to reduce the friction resistance of the through part with the support frame 4. The limiting rod 6 slides through the support frame 4, and in the lifting process, it is like two accurate guide rails, strictly restricting the movement trajectory of the lifting frame 10, so that it can only make stable lifting in the vertical direction along the screw rod 8, effectively preventing the edge cutting accuracy problem caused by shaking or deviation.

[0029] When the lifting frame 10 reaches the specified height, the adapter frame 11 installed thereon begins to play a role. The adapter frame 11 is provided with a cutter 12 through a set of strict fixing mechanism. The fixing mechanism here selects a bolt assembly 13 installed on the adapter frame 11, and the cutter 12 is provided with a fixing groove corresponding to the bolt assembly 13. This connection method is simple and practical, and can also ensure that the cutter 12 is firmly fixed on the adapter frame 11 during high-strength edge cutting operation, and will not appear loose or displacement phenomenon.

[0030] The cutter 12 itself is forged from high-hardness and high-wear-resistance alloy steel material through special process, and the sharp and durable blade can easily cope with the edge cutting task of environmental protection carton paperboard 3 of various thicknesses.

[0031] Above the placing groove 2, a fixed plate 5 is provided, and a design ingenious cavity 16 is hidden inside the fixed plate 5, which is the key to realize the environmental protection function of the whole device. The piston plate 17 is sealingly and slidingly provided in the cavity 16 through a set of elastic mechanism. The elastic mechanism includes a spring 18 arranged in the cavity 16, and the two ends of the spring 18 are respectively connected with the inner wall of the cavity 16 and the outer wall of the piston plate 17. When the device is running, the movement state of the stabilizing frame 9 will be transmitted to the piston plate 17 through the adapter mechanism. The adapter mechanism includes a cross plate 14 installed on the stabilizing frame 9, and the cross plate 14 is provided with an adapter rod 15 connected with the piston plate 17. With the movement of the stabilizing frame 9 up and down following the rotation of the screw rod 8, the piston plate 17 also makes a sealing sliding movement in the cavity 16.

[0032] At the same time, the fixed plate 5 is provided with a blowing port 19 and an air inlet 20 communicating with the cavity 16, the blowing port 19 is provided with a first valve, and the air inlet 20 is provided with a second valve, and the first valve and the second valve are both one-way valves. When the piston plate 17 moves downward, the air pressure in the cavity 16 increases, at this time the first valve opens, and the air is blown out through the blowing port 19, so that the debris on the paperboard 3 is blown away, avoiding affecting the blade of the cutter 12. When the piston plate 17 moves upward, a negative pressure is formed in the cavity 16, and the second valve opens, and the outside air enters the cavity 16 through the air inlet 20 to reserve air for the next blowing action.

[0033] The utility model uses, place paperboard 3 in the placing groove 2, subsequently start drive motor 7 makes it drive screw rod 8 rotation, when screw rod 8 rotates, elevating support 10 is driven cutting knife 12 to descend with the help of the interface frame 11, and the edge operation is carried out to paperboard 3, before this, fixed plate 5 first contact paperboard 3, in the process of cutting knife 12's continuous descent, gradually increase the pressure degree of paperboard 3's pressing down, and spring 18 is gradually stretched, piston plate 17 drops, when dropping, the gas in cavity 16 can be blown out through the air outlet 19, before cutting knife 12 contact paperboard 3, the granular impurity is blown away, avoid the influence of the blade of cutting knife 12.

[0034] The above, only for the preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this, any skilled in the art technical personnel in the utility model disclosed in the technical range, according to the utility model technical scheme and the utility model concept are equivalent to replace or change, all should be covered in the protection scope of the utility model.
