DETAILED DESCRIPTION

[0030] The specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present application, and are not intended to limit the present application.

[0031] In the present application, the orientation words contained in the terms "upper, lower, top, bottom, inner, outer" and the like only represent the orientation of the terms in the normal use state, or the common name understood by those skilled in the art, and should not be regarded as a limitation of the terms.

[0032] The first aspect of the present application provides a cutting head, as shown in Figure 1 , Figure 2 The cutting head 1 includes a cutting part at the upper part and a connecting part at the lower part for connecting the cutting motor 6, the cutting part is provided in a semi-spherical shape, and a plurality of parallel cutting tooth rings 2 are arranged on the spherical surface, the protruding teeth in each cutting tooth ring 2 are distributed at equal intervals, the gap between adjacent protruding teeth is a tooth groove, and the tooth spacing in any two cutting tooth rings 2 is equal.

[0033] The lower part of the cutting head 1 is fixedly installed on the rotating shaft of the motor, and different textures can be cut on the surface of the profile 15 by changing the inclination angle of the cutting head 1. During cutting, the protruding teeth play a role in cutting off the material, and the tooth groove plays a role in removing the chips. The radius difference of any two adjacent cutting tooth rings 2 is set to be equal.

[0034] The second aspect of the present application provides a wood grain texture cutting device for a profile surface, as shown in Figure 3 , Figure 4 , and Figure 5 The wood grain texture cutting device 19 includes an open-top inner frame 3 and an outer frame 4, a cutting mechanism with the head upward is fixedly installed in the inner frame 3, the two sides of the upper part of the inner frame 3 are rotatably connected to the outer frame 4 through the pin shaft 5, and the lower part of the inner frame 3 is further provided with a swing mechanism for driving the inner frame 3 to swing back and forth around the pin shaft 5. It should be noted that the bottom of the inner frame 3 should be kept at a certain distance from the bottom of the outer frame 4 to avoid collision between the inner frame 3 and the outer frame 4 when the inner frame 3 swings.

[0035] The cutting mechanism includes a cutting motor 6 mounted on the bottom plate of the inner frame 3, and the cutting head 1 described above.

[0036] When using the wood grain texture cutting device 19, the device is arranged below the profile 15, and the profile 15 to be cut moves linearly from above the device at a constant speed. When the cutting head 1 contacts the profile 15, the high-speed rotating cutting head 1 will cut off the material of the profile 15 to form a concave indentation under the driving of the cutting motor 6.

[0037] While the cutting motor 6 controls the rotation of the cutting head 1, the swing mechanism drives the entire inner frame 3 and the cutting mechanism mounted on the bottom plate of the inner frame 3 to reciprocate around the pin shaft 5, that is, the cutting head 1 has the action of reciprocating around the pin shaft 5 in addition to high-speed rotation, so that different cutting tooth rings 2 on the cutting head 1 can cooperate to cut the surface of the profile 15 to form a cutting pattern similar to the original wood grain. It should be noted that the cutting texture should not be too deep, and is preferably controlled between 0.1-0.5mm. The aluminum alloy profile 15 treated by the device can be further powder sprayed with wood grain transfer and electrophoretic wood grain transfer, and the final effect is consistent with the real wood texture, has a real wood texture three-dimensional effect when viewed from the side, has a real wood texture touch when touched, maximizes the real wood effect of the surface of the aluminum alloy profile 15, and improves the range of application of the aluminum alloy profile 15 in the form of real wood.

[0038] As an embodiment of the present application, the swing mechanism includes a swing motor 7 fixedly mounted on the outside of the outer frame 4, a rack 8 fixedly mounted on the outside of the inner frame 3, and a gear 9 fixedly mounted on the output end of the swing motor 7 and engaged with the rack 8. The rack 8 is arranged as an arc-shaped rack with the center coinciding with the axis of the pin shaft 5.

[0039] The swing motor 7 can be a servo motor, which drives the gear 9 to reciprocate, and the gear 9 drives the rack 8 engaged therewith to reciprocate when rotating. Since the rack 8 is fixedly connected to the outside of the inner frame 3, the rack 8 drives the inner frame 3 and the cutting mechanism mounted in the inner frame 3 to reciprocate. Through the cooperation of the gear 9 and the rack 8 mounted on the inner frame 3, the distance between the rack 8 and the pin shaft 5 is large, the swing arm is large, and the load of the servo motor is reduced. Other swing mechanisms can also be used, for example, a large gear is mounted on the pin shaft 5, a small gear on the motor is connected to the large gear through a chain, and the pin shaft 5 is directly driven to rotate, driving the inner frame 3 and the cutting mechanism to rotate.

[0040] In one embodiment of the present invention, to protect the cutting head 1, the wood grain cutting device 19 further includes a cutting head baffle 10 sleeved on the cutting head 1. The top surface of the cutting head baffle 10 is an arc-shaped surface with its center located on the axis of the pin 5. The cutting head baffle 10 is mounted on the inner frame 3 and swings synchronously with the inner frame 3 and the cutting structure. Setting the top surface of the cutting head baffle 10 as an arc-shaped surface coaxial with the pin 5 ensures that the distance between the cutting head baffle 10 and the profile 15 remains constant during swinging, preventing interference between the cutting head baffle 10 and the profile 15. A through hole is provided at the top of the cutting head baffle 10 so that the top of the cutting head 1 can protrude from the cutting head baffle 10, allowing the cutting head 1 to perform cutting work normally.

[0041] As one embodiment of the present invention, the cutter head baffle 10 is composed of a left baffle and a right baffle arranged symmetrically. The left baffle and the right baffle are respectively fixedly connected to the left inner wall and the right inner wall of the inner frame 3. The fixed connection can be made by screw connection. In order to facilitate installation, the screw enters the inner frame 3 and the cutter head baffle 10 from the outside of the inner frame 3.

[0042] In one embodiment of the present invention, the lower end of the cutting motor 6 is fixedly mounted to the base plate of the inner frame 3 by screws, and a shim is provided between the cutting motor 6 and the base plate. The height of the cutting head 1 can be adjusted by controlling the thickness of the shim. The thickness of the shim can be controlled by replacing shims of different thicknesses or by increasing or decreasing the number of shims.

[0043] Because the cutting head 1 rotates while simultaneously undergoing a reciprocating oscillation, when the center of the spherical surface at the top of the cutting head 1 deviates from the axis of the pin 5, the cutting depth of the cutting head 1 on the profile 15 changes from deep to shallow and then from shallow to deep during the oscillation process, continuously cycling to create textures of varying depths that better match the original wood grain. By changing the height of the cutting head 1, the maximum and minimum cutting depths can be altered.

[0044] In one embodiment of the present invention, both the outer frame 4 and the inner frame 3 are U-shaped frames composed of two side plates and a bottom plate, and the bottom plate and the side plates are fixedly connected by screws.

[0045] A third aspect of the present invention provides a wood grain processing device for profile surfaces, such as... Figure 6 As shown, the wood grain processing equipment includes a frame 11, rollers 12 arranged on both sides of the frame 11 for conveying profiles 15, a transmission motor for driving the rollers 12, a workpiece clamping device 14 arranged above the frame 11, and the aforementioned wood grain texture cutting device 19 installed between the two rollers 12. The workpiece clamping device 14 is used to press against the profiles 15 to prevent the profiles 15 from moving upward during the texture cutting process.

[0046] When the wood grain processing equipment is used to cut wood grain on the surface of the profile groove, first, the profile 15 is placed on the frame 11. It should be noted that, in order to ensure that the wood grain texture cutting device 19 can cut from one end of the profile 15 to the other end, the profile 15 needs to be placed from the upstream of the wood grain texture cutting device 19 (in the present application, the upstream and downstream are determined according to the order of contacting the profile 15. During the movement of the profile 15, the first to contact the profile 15 is the upstream, and the last to contact the profile 15 is the downstream). In addition, the number of rollers 12 should be determined according to the length of the profile 15. The shorter the profile 15, the more densely the rollers 12 should be arranged. Without the cooperation of other roller structures, the profile 15 should be in contact with at least two rollers 12 at the same time to keep the profile 15 stable. At the same time, the workpiece pressing device 14 is elongated to press the profile 15 from above, so as to avoid the movement of the profile 15 in the vertical direction during the cutting process, which affects the contact with the cutting tool head 1, and further causes the cutting effect to be unsatisfactory.

[0047] The transmission motor can be a servo motor, which can control the moving speed of the profile 15 by changing the rotating speed. The servo motor drives the roller 12 to rotate to make the profile 15 move forward on the frame 11, so that the bottom surface of the profile 15 contacts the cutting tool head 1. When the profile 15 as a whole passes the cutting tool head 1, the wood grain cutting work is completed.

[0048] As an embodiment of the present application, the workpiece pressing device 14 includes a pneumatic cylinder 16 and a pressing wheel 17 installed on the end of the piston rod of the pneumatic cylinder 16. The piston rod of the pneumatic cylinder 16 is extended to drive the pressing wheel 17 to move downward and press on the upper surface of the profile 15. After the cutting is completed, the piston rod is retracted.

[0049] As an embodiment of the present application, as shown in Figure 6 、 Figure 7 and Figure 8 , the wood grain processing equipment further includes a burr removing device 18 installed on the frame 11, which is used to remove the burrs generated on the surface of the profile 15 during cutting. The burr removing device 18 is arranged downstream of the wood grain texture cutting device 19. The burr removing device 18 includes a burr removing frame 21 fixedly connected by three plate bodies. The burr removing frame 21 is fixedly installed on the frame 11. The burr removing frame 21 is rotationally connected with a steel brush roller 22 through a shaft. The shaft of the steel brush roller 22 is connected with a roller pulley 23. The bottom plate of the burr removing frame 21 is installed with a burr removing motor 24. The output shaft of the burr removing motor 24 is connected with a motor pulley 25. The motor pulley 25 and the roller pulley 23 are connected through a synchronous transmission belt 26.

[0050] As an embodiment of the present application, as shown in Figure 6 and Figure 9As shown, the wood-texturing apparatus further comprises a polishing device 20 mounted on the frame 11, which is arranged downstream of the burr-removing device 18. The polishing device 20 has the same structure as the burr-removing device 18, except that the steel brush roller 22 is replaced by a polishing felt roller 27.

[0051] The preferred embodiments of the present application are described in detail above with reference to the drawings, but the present application is not limited thereto. Various simple modifications can be made to the technical solutions of the present application within the technical concept of the present application, including the combination of various specific technical features in any suitable manner. In order to avoid unnecessary repetition, various possible combination manners are not described again in the present application. However, these simple modifications and combinations should also be regarded as the disclosed content of the present application and belong to the protection scope of the present application.
