Description

Technical Field

[0001] The utility model relates to the technical field of paper box cutting, in particular to a cutting device of a paper box cutting machine. Background Art

[0002] The carton cutting machine is an important equipment that plays a key role in the field of carton processing and production. Its core function is to be able to carefully and accurately cut various types and specifications of cardboard according to the precise size and specific shape set in advance. This process is designed to meet the market's different production needs for diversified carton products, covering various types of carton boxes from common gift boxes, shoe boxes, to food packaging boxes and other purposes.

[0003] However, previous carton cutting machines have obvious defects and deficiencies in dust collection. Due to the poor dust collection effect, a large amount of dust and debris generated during the cutting process can easily spread around the working area. This not only seriously affects the operator's clear vision, making it difficult to accurately control the cutting process and quality, but also poses a serious threat to the operator's health. For example, some old-fashioned carton cutting machines rely solely on simple fans for dust collection. The dust collection capacity of this method is very limited, and it is often powerless to collect those tiny debris and cannot effectively collect them. In actual working scenarios, these uncollected tiny debris will float in the air, forming dust mist visible to the naked eye. Operators will inevitably inhale these dust and debris when they are in such an environment for a long time. Over time, respiratory diseases such as coughing, asthma, etc. may be caused, and even irreversible damage to the lungs may be caused. In addition, the diffused dust and debris may also be deposited on key components of the equipment, affecting the normal operation and service life of the equipment. In order to address the above problems, a cutting device for a carton cutting machine is proposed. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-3 , a cutting device of a carton cutting machine. First, a fixed frame 1 is provided inside the cutting machine, which is like a solid foundation of the entire device, providing a stable installation foundation for subsequent components. On this stable fixed frame 1, a lifting cylinder 2 is carefully installed, which plays a vital role and provides the necessary power support for the subsequent cutting operation.

[0021] At the same time, the fixed frame 1 is also equipped with a cutting knife 3, which is a key component for achieving accurate cutting of the paper box. It is worth mentioning that the fixed frame 1 is provided with a driving motor 9 closely connected to the cutting knife 3 through a specially designed supporting mechanism. This supporting mechanism is specifically manifested as a supporting frame 8 installed on the fixed frame 1. The supporting frame 8 is L-shaped and has good stability and supporting effect. The driving motor 9 is firmly installed on the supporting frame 8 by welding to ensure that it will not be loose or displaced during the working process.

[0022] In addition, two installation boxes 4 are installed on the fixed frame 1. Inside the two installation boxes 4, a rotating chamber 13 and a movable chamber 14 are respectively provided. In the rotating chamber 13, a reciprocating screw 11 extending to the bottom of the installation box 4 is cleverly rotated. The reciprocating screw 11 is tightly connected to the drive motor 9 through a carefully designed rotating mechanism. The rotating mechanism includes a driving gear 10 installed on the output shaft of the drive motor 9, and a transmission gear 12 meshing with the driving gear 10 is installed on the reciprocating screw 11. Through such a gear transmission combination, effective transmission and precise control of power are ensured.

[0023] A piston plate 15 is provided in the active chamber 14, and the piston plate 15 is connected to the reciprocating screw 11 through an ingeniously designed connection mechanism. The connection mechanism is specifically a connection frame 16 threadedly sleeved on the reciprocating screw 11, and the connection frame 16 is U-shaped, and both ends thereof are fixedly connected to the piston plate 15, thereby realizing accurate transmission of reciprocating motion.

[0024] Furthermore, a dust cover 7 is provided on the mounting box 4 through two dust suction pipes 5 for collecting dust and debris generated during the cutting process. An interception net is also installed in the dust cover 7, which is installed in the dust cover 7 by a bolt assembly, so as to facilitate subsequent disassembly, cleaning and maintenance.

[0025] At the same time, a dust outlet pipe 6 is also installed on the installation box 4. In order to better control the dust suction and dust discharge process, a first valve is provided in the dust suction pipe 5, and a second valve is provided in the dust outlet pipe 6, and both the first valve and the second valve are one-way valves, ensuring the unidirectionality and stability of the flow of gas and dust.

[0026] When the utility model is used, when the carton cutting machine starts working, the driving motor 9 starts to run. The output shaft of the driving motor 9 drives the driving gear 10 to rotate. Since the driving gear 10 is meshed with the transmission gear 12 on the reciprocating screw 11, the reciprocating screw 11 rotates in the rotating chamber 13. The connecting frame 16 threadedly sleeved on the reciprocating screw 11 will reciprocate up and down with the rotation of the screw. Because the two ends of the connecting frame 16 are fixedly connected to the piston plate 15, the piston plate 15 also reciprocates up and down in the active chamber 14. When the piston plate 15 moves downward, the pressure in the installation box 4 decreases, and the air at the dust hood 7 carries the dust and debris generated during the cutting process and is sucked into the installation box 4 through the dust suction pipe 5 (the first valve in the dust suction pipe 5 is open at this time). When the piston plate 15 moves upward, the pressure in the installation box 4 increases, and the dust and debris in the box are discharged through the dust outlet pipe 6 (the second valve in the dust outlet pipe 6 is open at this time) under the action of pressure. A collecting bag may be provided at the end of the dust outlet pipe 6 to collect the above-mentioned dust and debris.

[0027] During the entire cutting process, the lifting cylinder 2 drives the cutting knife 3 to lift and lower to cut the carton. For example, in the actual carton cutting work, if the cut carton material produces a lot of debris, the rapid reciprocating motion of the piston plate 15 can promptly suck these debris into the installation box 4 to prevent the debris from flying and affecting the working environment and cutting accuracy. Among them, the carton raw material is placed and fixed by other equipment components of the cutting machine. The specific structure is not drawn and described in this scheme. Please refer to the prior art for details.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
