Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wood processing equipment, and more specifically to a wood rotary cutting device. Background Art
[0002] In the field of wood processing, there are two main types of rotary peeling machines, namely, the non-clamped shaft peeling machine and the clamped shaft peeling machine, which have their own unique advantages and disadvantages in structure and use. First of all, the design of the non-clamped shaft peeling machine has shown higher flexibility when processing materials of different shapes and sizes due to the lack of clamped shaft. However, due to the lack of clamped shaft fixation, the non-clamped shaft peeling machine may have certain deficiencies in cutting accuracy and stability. In addition, the non-clamped shaft design may also cause the material to slip or deviate when running at high speed, affecting the cutting quality. The design of the clamped shaft peeling machine is known for its high precision and stability. The existence of the clamped shaft enables the peeling machine to fix the log more accurately during the cutting process, ensuring the accuracy and stability of the cutting. Therefore, the clamped shaft peeling machine shows better performance when processing materials with higher precision requirements. However, the clamped shaft design also brings some limitations. Due to the existence of the clamped shaft, the clamped shaft peeling machine may not be as flexible as the non-clamped shaft peeling machine when processing materials of different shapes and sizes. In summary, both the non-shaft peeling machine and the shaft peeling machine have their own advantages and disadvantages. When choosing a peeling machine, you need to weigh the specific processing requirements and material properties. In order to better meet market demand, the research and innovation of peeling machine technology has important practical significance and application value. Summary of the invention

[0028] The following is a further description of the specific implementation of the utility model in conjunction with the drawings of the specification, so that the technical solution and its beneficial effects of the utility model are clearer and more explicit. The following description of the embodiments with reference to the drawings is exemplary and intended to explain the utility model, and cannot be understood as limiting the utility model.
[0029] like Figure 1-Figure 4As shown, the utility model is a wood peeling device, comprising a frame 1 and a three-roller centering drive mechanism arranged thereon, a peeling knife table 2, a pressure ruler 3, a knife table mounting plate 4 and a knife angle rotating mechanism 5, the three-roller centering drive mechanism comprising a front roller assembly 6, an upper roller assembly 7, and a lower roller assembly 8 which are driven separately; the front roller assembly 6 comprises a front friction roller 6-1 and a front roller lead screw slider guide rail module 6-2, and the front friction roller 6-1 is movably arranged on the front roller lead screw slider guide rail module 6-2; the upper roller assembly 7 comprises an upper friction roller 7-1 and an upper roller lead screw slider guide rail module 7-2, and the upper friction roller is movably arranged on the upper roller lead screw slider guide rail module; the lower roller assembly 8 comprises a lower friction roller 8-1 and a lower roller lead screw slider guide rail module 8-2, and the lower friction roller is movably arranged on the lower roller lead screw slider guide rail module; the friction roller, the upper friction roller, and the lower friction roller are driven by separately controlled motors respectively. The front roller screw slider guide rail module 6-2 includes a front roller slider guide rail 6-21, a front roller screw 6-22 and a front roller motor device 6-23 connected to drive the front roller screw. The front roller motor device drives the front friction roller to move along the front roller slider guide rail through the front roller screw. The upper roller screw slider guide rail module and the lower roller screw slider guide rail module are consistent in structure with the front roller screw slider guide rail module, which will not be described in detail here. The front roller slider guide 6-21 includes a front roller guide one and a front roller guide two that are parallel to each other, and a front roller slider. The front roller slider is movably arranged on the front roller guide one and the front roller guide two. The end of the front friction roller is fixed on the front roller slider, so that the front friction roller can slide linearly along the front roller slider guide. The upper roller slider guide and the lower roller slider guide are consistent in structure with the front roller slider guide, which will not be described in detail here.
[0030] The knife angle rotating mechanism 5 is connected between the rotary cutter table and the knife table mounting plate. A pressure ruler screw slider guide rail module is provided on the frame, and the pressure ruler is movably installed on the pressure ruler screw slider guide rail module. The knife angle rotating mechanism 5 includes a knife angle rotation drive motor and a knife angle rotation transmission gear set. The rotation drive motor is connected to drive the rotary cutter table through the knife angle rotation transmission gear set. The knife angle rotation drive motor is arranged on the knife table mounting plate. A tool 9 is arranged on the rotary cutter table, and a small relative rotation movement is performed with the knife tip as the center. By adjusting the angle of the knife angle, accurate rotary cutting of logs of different diameters can be achieved. The pressure ruler is located on the rotary cutter table and maintains relative motion with the rotary cutter table. Its main function is to control the thickness of the rotary cut plate and remove burrs on the plate surface. During the rotary cutting process, the pressure ruler can be adjusted according to the requirements of the plate thickness, and can remove burrs on the plate surface to improve the surface quality of the plate. When the log is rotary cut to the minimum wood diameter, the pressure ruler can tighten the gap between it and the rotary cutter, so that the wood core falls naturally, avoiding the rest of the cumbersome operations.
[0031] Compared with the prior art, the utility model cancels the single and double roller settings in the traditional design, and instead introduces three independently driven friction rollers. This design allows the center of the log to remain stable during the peeling process, thereby effectively improving the peeling quality. By precisely controlling the drive speed and position of the three friction rollers, we can achieve precise peeling of logs of different sizes and shapes, while reducing the cutting error caused by the offset of the center of the circle. Secondly, the independent drive between the peeling tool station and the single roller is achieved. This design allows the stability of the log during the peeling process to be maintained without changing the pressure difference. By independently controlling the drive system of the peeling tool station and the single roller, we can achieve precise adjustment when the cutting changes, thereby adapting to the processing requirements of different materials. This design not only improves the peeling efficiency, but also reduces the cutting quality problems caused by material slippage or deviation.
[0032] In this technical solution, by introducing three independently driven friction rollers and an independent drive system between the rotary cutting tool table and the single roller, precise control and optimization of the rotary cutting process is achieved. This new concept of rotary cutting equipment not only improves the rotary cutting accuracy and stability, but also enhances the flexibility of the processing process, providing a new solution for efficient and high-quality rotary cutting.
[0033] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, and these modifications and improvements all fall within the protection scope of the present invention.
