Description

Technical Field

[0001] The utility model relates to the technical field of rotary cutters, in particular to a roller shaft structure of a double-section split rotary cutter. Background Art

[0002] The working principle of the cardless rotary cutter is that the motor drives the single and double rollers to rotate, and then the rotating single and double rollers drive the wood segment to rotate and cooperate with the feed screw to push the knife holder forward. The knife holder is equipped with a blade, and the feed speed is automatically adjusted according to the set thickness to complete the rotary process; the fixed-length cutting is composed of rubber rollers, rotary cutters, motors and electronic control systems. Its working principle is: when the spun veneer passes through the rubber rollers, the rotation speed of the rotary cutter is controlled by the pre-set parameters, and one rotation and cutting is performed to obtain a fixed-length veneer.

[0003] When the traditional peeling machine is working, the upper roller of the double roller is subjected to a great pressure (much greater than the lower roller) when driving the peeling of wood. According to the principle of mechanics, the farther the fulcrum is, the longer the cantilever is. Under the same pressure, the weaker the strength of the force point is, the easier it is to deform. Therefore, when the upper roller of the double roller is a single roller, the midpoint strength of the roller shaft is the weakest and it is easy to deform and break. In view of this, this application is specially proposed. Utility Model Content

[0004] The present application proposes a double-stage split-type peeling machine roller structure to solve the technical problem in the prior art that the upper roller of the double roller is subjected to a large pressure (much larger than the lower roller) when driving the wood peeling. According to the principle of mechanics, the farther the fulcrum is, the longer the cantilever is. Under the same pressure, the weaker the strength of the force point is, the easier it is to deform. Therefore, when the upper roller of the double roller is a single roller, the midpoint strength of the roller is the weakest and it is easy to deform and break. The above technical purpose of the utility model is achieved through the following technical solutions:

[0005] The roller structure of a double-stage split peeling machine includes a base, a double-axis support, a middle seat, a first upper roller, a second upper roller, a lower roller and a roller. The double-axis support is symmetrically arranged on both sides of the base, the middle seat is arranged in the middle position of the base, and a plurality of rollers are rotatably arranged on the middle seat. The first upper roller is arranged between the double-axis support and the middle seat on one side, the second upper roller is arranged between the double-axis support and the middle seat on the other side, and the lower roller is arranged between the double-axis supports on both sides. The lower roller passes through the middle seat, and the lower roller is in contact with and cooperates with the roller.

[0006] Preferably, the middle seat comprises a lower base and an upper base, the lower base is fixed in the middle of the base by bolts, and the lower base and the upper base are connected by bolts.

[0007] Preferably, the lower base and the upper base are both in a "3" shape, and two circular cavities are formed between the closed lower base and the upper base.

[0009] Preferably, the number of the rollers is seven.

[0010] Preferably, the first upper roller, the second upper roller and the lower roller are all stepped shafts.

[0011] Compared with the prior art, the beneficial effects of the utility model include: by providing the first upper roller and the second upper roller, the split design of the upper roller effectively reduces the load pressure of the single roller shaft, and the split upper roller is not easy to deform, thereby significantly improving the service life and stability of the roller shaft; by providing the middle seat, the setting of the middle seat can provide an additional fulcrum for the installation support of the lower roller.

In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0019] Please see attached Figure 1-3 The roller structure of the double-stage split peeling machine includes a base 1, a double-axis support 2, a middle seat 3, a first upper roller 4, a second upper roller 5, a lower roller 6 and a roller 7. The double-axis support 2 is symmetrically arranged on both sides of the base 1, the middle seat 3 is arranged in the middle position of the base 1, and a plurality of rollers 7 are rotatably arranged on the middle seat 3. The number of rollers 7 is seven. The lower base 8 on the middle seat 3 is provided with a groove matching the shape of the roller 7. The length of the roller 7 is less than the length of the groove. The first upper roller 4 is arranged between the double-axis support 2 and the middle seat 3 on one side, the second upper roller 5 is arranged between the double-axis support 2 and the middle seat 3 on the other side, and the lower roller 6 is arranged between the double-axis supports 2 on both sides. The lower roller 6 passes through the middle seat 3, and the lower roller 6 is in contact with the roller 7.

[0020] In some embodiments, the middle seat 3 includes a lower base 8 and an upper base 9, the lower base 8 is fixed in the middle of the base 1 by bolts, the lower base 8 and the upper base 9 are connected by bolts, the lower base 8 and the upper base 9 are both in the shape of "3", and two circular cavities are formed in the middle of the closed lower base 8 and the upper base 9, the first upper roller 4 and the second upper roller 5 pass through the upper circular cavity, and the lower roller 6 passes through the lower circular cavity. In detail, the middle seat 3 adopts a separate structure of the lower base 8 and the upper base 9, the two are tightly connected by bolts, forming two relatively independent circular cavities, which is convenient for installation and maintenance, and also enhances the overall rigidity of the structure.

[0021] With the above technical solution, the double-axis support 2 is symmetrically installed on both sides of the base 1, ensuring the stability and load-bearing capacity of the entire structure. The middle seat 3 is placed at the center of the base 1 and is fastened to the base 1 by bolts, becoming the core hub connecting the first upper roller 4, the second upper roller 5 and the lower roller 6;

[0022] By setting the first upper roller 4 and the second upper roller 5, since the pressure on the double-roller upper roller is very large when driving the wood peeling, according to the principle of mechanics, the farther the fulcrum is, the longer the cantilever is. Under the same pressure, the weaker the strength of the force point is, the easier it is to deform. The split design of the upper roller is not easy to deform, which effectively reduces the load pressure of a single roller shaft, thereby significantly improving the service life and stability of the upper roller;

[0023] By setting the middle seat 3, the setting of the middle seat 3 can provide an additional fulcrum for the installation support of the lower roller 6. According to the principle of mechanics, under the same pressure, the strength of the lower roller 6 is increased and it is not easy to be broken. By setting rollers 7 on the middle seat 3, the friction during rotation is reduced, and the wear resistance of the lower roller 6 is greatly improved. At the same time, the number of rollers 7 (seven) and the arrangement of the rollers 7 ensure the stability and uniformity of the lower roller 6 during the rotation process, further improving the processing efficiency and product quality of the peeling machine.

[0024] In the wood processing peeling machine, the roller structure of the present application can efficiently drive the wood segment to rotate and cooperate with the feed screw to push the tool holder forward, so that the wood surface is evenly and continuously peeled into slices. When the external drive device is started, the first upper roller 4, the second upper roller 5 and the lower roller 6 rotate synchronously, thereby driving the wood segment to rotate. The setting of the roller 7 reduces the wear of the lower roller 6 and ensures the continuity and stability of the peeling process.

[0025] In some embodiments, the first upper roller 4, the second upper roller 5 and the lower roller 6 are all stepped shafts.

[0026] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation on the present invention.
