Detailed Description
In order to describe the technical contents, the achieved objects and effects of the present invention in detail, the following description will be made with reference to the embodiments in conjunction with the accompanying drawings.
Referring to fig. 1 to 3, the invention relates to a method for removing scars on the outer wall of a bamboo tube 4, comprising the following steps:
step 1: sleeving an inner hole of the bamboo tube 4 on the positioning roller 2;
step 2: the circumferential surface of the pressing roller 3 is pressed on the outer wall of the bamboo tube 4;
step 3: the cutting edge 51 of the cutter 5 contacts the outer wall of the bamboo tube 4;
step 4: the positioning roller 2 drives the bamboo tube 4 to rotate, so that the cutter 5 cuts the scab on the outer wall of the bamboo tube 4.
In the method for removing the outer wall scars of the bamboo tube 4, the positioning roller 2 and the pressing roller 3 are utilized to position and clamp the bamboo tube 4 to be processed, then the cutter 5 is moved to enable the blade 51 of the cutter to contact the outer wall of the bamboo tube 4, and the positioning roller 2 rotates to drive the bamboo tube 4 to rotate, so that the cutter 5 cuts the scars of the outer wall of the bamboo tube 4, the structure for positioning and clamping the bamboo tube 4 to be processed by utilizing the positioning roller 2 and the pressing roller 3 is particularly suitable for removing the outer wall scars of the irregular bamboo tube 4, and the bamboo tube 4 has basically consistent thickness in all directions even though the roundness is not high, thereby ensuring that the outer wall of the irregular bamboo tube 4 is uniformly polished, not only completely removing the outer wall scars of the bamboo tube 4, but also avoiding excessive polishing of the bamboo material, ensuring the high utilization rate of the bamboo material, and the utilization rate of the bamboo material can reach more than 90%.
Further, in the method for removing the scab on the outer wall of the bamboo tube 4, the step 3 specifically includes: the cutter 5 is moved, so that the cutting edge 51 of the cutter 5 contacts the outer wall of the bamboo tube 4, and the distance between the contact position of the cutting edge 51 and the outer wall of the bamboo tube 4 and the press joint position of the press roller 3 and the outer wall of the bamboo tube 4 is smaller than 3cm.
As is clear from the above description, in step 3, the blade 51 of the cutter 5 needs to be close to the position where the pressing roller 3 contacts the outer wall of the bamboo tube 4, because when the roundness of the bamboo tube 4 is not high, when the bamboo tube 4 is sleeved with the positioning roller 2 and clamped by the pressing roller 3, the closer to the position where the pressing roller 3 contacts the outer wall of the bamboo tube 4, the higher the positioning stability, and when the cutter 5 is close to the position, the scab on the outer wall of the bamboo tube 4 can be removed more uniformly and completely.
Further, in the method for removing the scab on the outer wall of the bamboo tube 4, the step 1 specifically includes: the inner hole of the bamboo tube 4 is sleeved on the positioning roller 2 in a transition fit manner.
As can be seen from the above description, the positioning roller 2 adopts a detachable structure, and positioning rollers 2 with different diameters are selectively installed according to the specifications of the bamboo tube 4, so that the positioning roller 2 is in transition fit with the inner holes of the bamboo tube 4, and thus the stability of positioning the bamboo tube 4 can be improved when the positioning roller 2 and the press roller 3 are matched to clamp the bamboo tube 4, and shake caused in the process of removing scars by the cutter 5 when the bamboo tube 4 rotates under the driving of the positioning roller 2 is avoided.
Further, in the method for removing the scab on the outer wall of the bamboo tube 4, the step 2 specifically includes: the circumferential surface of the pressing roller 3 is pressed on one side of the outer wall of the bamboo tube 4.
As can be seen from the above description, the pressing roller 3 is pressed on one side of the outer wall of the bamboo tube 4, so that the pressing roller 3 and the positioning roller 2 clamp the bamboo tube 4 from the side, and the structure makes the cutting edge 51 of the cutter 5 easier to approach the press connection part of the bamboo tube 4 and the pressing roller 3, so as to polish the outer wall of the bamboo tube 4 more stably and uniformly.
Referring to fig. 1-3, the present invention further relates to a device for removing scars on the outer wall of a bamboo tube 4, which comprises a base 1, a positioning roller 2, a pressing roller 3 and a cutter 5; the positioning roller 2 is rotatably connected to the base 1, the diameter of the positioning roller 2 is smaller than the minimum inner diameter of the bamboo tube 4, the pressing roller 3 is movably connected to the base 1, and the moving direction of the pressing roller 3 is the radial direction of the positioning roller 2; the cutting edge 51 of the cutter 5 is located between the positioning roller 2 and the pressing roller 3.
In the structure of the bamboo tube 4 outer wall scab removing device, the positioning roller 2 stretches into the inner hole of the bamboo tube 4, the bamboo tube 4 is clamped by the press roller 3 and the positioning roller 2, the positioning of the bamboo tube 4 is realized, the cutting edge 51 of the cutter 5 is close to the pressing part of the bamboo tube 4 on the press roller 3, the cutting edge 51 of the cutter 5 contacts the outer wall of the bamboo tube 4, the positioning roller 2 is controlled to rotate, the friction force between the positioning roller 2 and the inner wall of the bamboo tube 4 is utilized to drive the bamboo tube 4 to rotate, and the fixed cutter 5 and the rotating bamboo tube 4 generate relative displacement, so that scab on the outer wall of the bamboo tube 4 is removed.
Furthermore, in the structure of the scar removing device on the outer wall of the bamboo tube 4, the positioning roller 2 is in transition fit with the inner wall of the bamboo tube 4.
As can be seen from the above description, the positioning roller 2 adopts a detachable structure, and positioning rollers 2 with different diameters are selectively installed according to the specifications of the bamboo tube 4, so that the positioning roller 2 is in transition fit with the inner holes of the bamboo tube 4, and thus the stability of positioning the bamboo tube 4 can be improved when the positioning roller 2 and the press roller 3 are matched to clamp the bamboo tube 4, and shake caused in the process of removing scars by the cutter 5 when the bamboo tube 4 rotates under the driving of the positioning roller 2 is avoided.

Furthermore, in the structure of the scar removing device on the outer wall of the bamboo tube 4, the diameter of the pressing roller 3 is smaller than that of the positioning roller 2.
The structure facilitates the cutter 5 to move to a position close to the contact of the bamboo tube 4 and the press roller 3.
Furthermore, in the structure of the scar removing device on the outer wall of the bamboo tube 4, the axis of the positioning roller 2 and the axis of the press roller 3 are positioned in the same plane, and the included angle between the plane and the horizontal plane is 0-45 degrees.
As can be seen from the above description, the axis of the positioning roller 2 and the axis of the pressing roller 3 are located in the same plane, i.e. the positioning roller 2 is parallel to the pressing roller 3, and the fact that the plane has a certain included angle with the horizontal plane has the advantage that when the cutter 5 moves horizontally on the base 1, the cutter 5 is convenient to move to a position close to the contact position of the bamboo tube 4 and the pressing roller 3.
Example 1
