Description

Technical Field

[0001] This utility model relates to the field of cutting machine technology, and in particular to a floor cutting machine. Background Technology

[0002] In the woodworking industry, the board cutting machine is a key piece of equipment for cutting and angle processing of boards. Its performance directly affects product accuracy and production efficiency. Traditional board cutting machines have many prominent problems in practical applications. First, the angle cutting function is limited and switching is cumbersome. Most existing equipment only supports fixed angle cutting. If different angle beveling is required, manual calibration with tools such as protractors and clamps is necessary. This not only complicates the operation but also makes the angle error prone to fluctuations depending on the operator's experience, leading to quality problems such as excessive gaps and dimensional inconsistencies. Although some multi-functional models have angle adjustment functions, they lack standardized markings and positioning structures. The adjustment process is time-consuming and has low precision, making it difficult to meet the needs of industries such as furniture manufacturing and decoration for irregular splicing and precise angle processing. This restricts the flexibility and efficiency of the process. Secondly, the operation is not adaptable enough and the labor intensity is high. The handle length of traditional cutting machines is mostly fixed, which cannot be adapted to the arm length, grip habits and working scenarios of different operators. This can easily cause fatigue due to uncomfortable posture, and even lead to operational errors. At the same time, the force transmission structure of some equipment is not reasonably designed. A large external force needs to be applied to maintain stability during cutting. The risk of muscle strain is high under long-term operation, and the fluctuation of force can easily cause the cutting trajectory to deviate, affecting the processing accuracy.

[0011] Compared with existing technologies, the beneficial effects achieved by this utility model are as follows: This utility model adopts a structured design. By integrating a multi-angle cutting positioning structure, the device achieves rapid response to diverse angle cutting needs, eliminating the need for frequent equipment changes or complex adjustments, significantly shortening process changeover time. Simultaneously, the handle length can be flexibly adjusted via positioning pins and pin holes. Combined with an optimized handle, roller, and transmission component force transmission structure, operators can adjust the lever arm according to the work scenario, reducing operational pauses and force loss, ensuring efficient and continuous cutting actions, significantly enhancing the equipment's adaptability to complex processing tasks, balancing customized processing flexibility with large-scale production efficiency. Furthermore, from an ergonomic perspective, the adjustable handle length design, relying on the precise locking function of the positioning pins, can adapt to the physiological characteristics of different operators' hands, ensuring comfortable grip and force application. The posture is more in line with the body's natural force exertion habits, reducing muscle fatigue during long-term operation. Multi-angle marking and positioning simplifies the adjustment process for angle cutting. Operators can quickly align the cutting benchmark without additional measuring tools, reducing human error. The two work together to optimize precise cutting and comfortable operation, which not only lowers the operating threshold but also improves the ease of use and operational stability of the equipment, adapting to the processing needs of various scenarios such as furniture manufacturing and decoration. The core transmission component connecting the power source and the cutting tool, the drive shaft, has a rigid design and precision machining process that can effectively reduce energy loss and vibration interference during power transmission. By optimizing the shaft diameter and material selection, the drive shaft can maintain structural stability during high-speed rotation or reciprocating motion, avoiding power fluctuations caused by deformation, and ensuring that the tool always maintains the constant speed or frequency required for cutting.
