[0001] The invention relates to the technical field of wood processing equipment, and more particularly to a wood workpiece profiling equipment and a processing method thereof. Background Art

[0002] The profiling equipment is a device that can automatically control the movement trajectory of the set tool or workpiece to perform surface processing according to the shape and size of the template or sample, so that the workpiece is formed into a specified shape. The wooden workpiece profiling equipment is one of many profiling equipment, which is used for processing wood. The wooden workpiece profiling equipment is generally composed of a workbench and a tool. The wood to be processed is set on the workbench, and the tool is set on the workbench surface on one side of the wood. During processing, the workpiece moves, and the high-speed rotating tool performs milling processing on the wooden workpiece.

[0003] The profiling equipment with the above structure has the characteristics of stable wood milling process and fast processing. However, since its milling cutter and the wood to be processed are both horizontally set in the manner commonly adopted by the current wood workpiece profiling equipment, the wood chips splashed during the processing are finally accumulated on the work surface under the action of gravity. Therefore, the movement path of the wood is easily affected by the accumulated wood chips and deviates from the reference plane, affecting the regularity of the processed surface. In order to avoid the influence of the accumulated wood chips on the quality of the final formed wooden workpiece, the work platform must be cleaned frequently, which increases the burden on the operator, resulting in the problem of cumbersome maintenance of the current profiling equipment. Summary of the invention

[0004] In view of the above situation, in order to overcome the problem that the wood workpiece profiling equipment in the above-mentioned prior art has the problem that the wood chips splashed during processing are eventually accumulated on the work surface, causing the wood to deviate from the predetermined moving path, affecting the regularity of the processed surface, and requiring high-frequency cleaning, increasing the burden on the operator, and cumbersome maintenance, the purpose of the present invention is to provide a wood workpiece profiling equipment that is not easy to accumulate on the work station in the process of wood processing, so as to prevent the wood chips from affecting the moving path of the wood, so that the processed surface of the finally obtained wood workpiece is regular, and does not require high-frequency cleaning, thereby being easy to maintain.

[0012] Preferably, two outer discs are provided, and the two outer discs are arranged on both sides of the central disc, and the second lobes on the two outer discs are opposite to the first lobes on the central disc.

[0013] Preferably, the cutter disc comprises a first cutter body and a second cutter body, the first cutter body and the second cutter body are spaced apart from each other, and are both distributed on the rotation path of the material turning disc, tangent to or away from the material turning disc.

[0014] Preferably, it further comprises a material collecting box, which is arranged below the material turning plate, and an opening of the material collecting box is opposite to the material turning plate.

[0015] A wood processing method of the above-mentioned wooden workpiece profiling device comprises the following steps:

[0031] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] In the description of the present invention, it should be noted that the directions or positional relationships indicated by the terms "upper", "lower", "left", "right", "inside", "outside", etc. are based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the product of the invention is usually placed when in use. They are only for the convenience of simplifying the description, and do not indicate or imply that the directions are specific directions that must be possessed, and specific directions structures and operations, and therefore should not be understood as limitations on the present invention.

[0033] like Figure 1 , Figure 2 , Figures 4 to 6As shown, the present invention provides a wooden workpiece profiling device, which includes: a feed box 1, a conveyor belt 2, a turning plate 3, a cutter disc 4 and an electric drive box 5, wherein the feed box 1 is used to collect the wood to be processed, the conveyor belt 2 is used to transport the wood to be processed, the turning plate 3 is used to receive the wood, that is, to receive the wood to be processed transported by the conveyor belt 2, and to control the moving trajectory of the wood, and the cutter disc 4 is used to perform surface processing on the wood to be processed received by the turning plate 3, wherein the feed box 1 and the turning plate 3 are respectively opposite to the inlet end and the outlet end of the conveyor belt 2, so that the wood to be processed put into the feed box 1 can directly enter the conveyor belt 2, and the conveyor belt 2 automatically turns to the turning plate 3. The material tray 3 is conveyed. The process in which the feed box 1 inputs the wood to be processed into the conveyor belt 2 and then is transported to the turning plate 3 by the conveyor belt 2 is the feeding process. The turning plate 3 and the knife disc 4 operate in a rotating manner. The turning plate 3 and the knife disc 4 are arranged perpendicular to the horizontal plane, so that the rotating plane is perpendicular to the horizontal plane, and the knife disc 4 is located below the turning plate 3, and it keeps tangent to or away from the turning plate 3, ensuring that the wood to be processed received can directly contact the knife disc 4 with the rotation of the turning plate 3, and be processed by the rotating knife disc 4. The above process is a milling process. The wood chip waste generated in the milling process can fall directly downward under the action of gravity without The turning plate 3 rotates with a fixed axis, so that each piece of wood received by the turning plate 3 can maintain a uniform movement trajectory, thereby ensuring the uniformity of the shape of the processed surface. The operator does not need to frequently clean the accumulated wood chips, thereby reducing the labor burden. Therefore, the wooden workpiece profiling machine of the present invention has the characteristic of simple maintenance. In addition, the rotating turning plate 3 makes the movement trajectory of the wood an arc-shaped trajectory with the rotation axis of the turning plate 3 as the origin. Therefore, the direction angle can be automatically adjusted during the movement of the wood, so that the processing is carried out as desired. For the processing surface that is not a straight surface, the turning plate 3 and the cutter disc 4 of the present invention are both arranged on different output shafts of the electric drive box 5, and are driven by the electric drive box 5 to rotate automatically, without the need for manual control of the rotation, so that the front and rear rotation speeds of the turning plate 3 and the cutter disc 4 can be kept consistent, and the labor intensity of on-site operators can be reduced. A material receiving trough 303a is provided on the side wall of the turning plate 3, and the material receiving trough 303a moves between a relative position and a detached relative position with the rotation of the turning plate 3 with the outlet end of the conveyor belt 2. It can be understood that when the relative position is reached, the turning plate 3 can collect the wood to be processed that passes through the conveyor belt 2 by the material receiving trough 303a.

[0034] like Figure 1 and Figure 2As shown, the feed box 1 is a vibrating plate. Here, it should be mentioned that the vibrating plate selected by the present invention can be any common vibrating plate on the market without any special restrictions. When working, the hopper of the feed box 1 which is a vibrating plate vibrates in a direction perpendicular to the horizontal plane, and the wood to be processed in the hopper continuously moves upward along the spiral track toward the conveyor belt 2 under the vibration of the hopper. During the rising process, the orientation angle of each wood to be processed is adjusted at the same time to maintain the same orientation angle when transported to the conveyor belt 2, ensuring that after being transported by the conveyor belt 2 to the turning plate 3, the cutter disc 4 mills the same part of each wood to be processed.

[0035] like Figures 1 to 3 As shown, the conveyor belt 2 includes a belt body 201, a tensioning wheel 202 and a diverter block 203. The belt body 201 is wound around the tensioning wheel 202, and the tensioning wheel 202 keeps the belt body 201 in a tensioned state. The tensioning wheel 202 is configured with multiple groups, and each tensioning wheel 202 is arranged at the same height or different heights. The belt body 201 presents different directions according to the arrangement orientation of the tensioning wheel 202, such as the belt body 201 extending horizontally, obliquely or zigzag, and can be freely set according to the setting orientation of the feed box 1 and the vibration plate. The diverter block 203 is opposite to the upper surface of the belt body 201, and the upper end surface of the belt body 201 is divided into two independent conveying positions. The wood to be processed passes through the belt body 201 on both sides of the diverter block 203, thereby increasing the amount of wood to be processed transported per unit time and improving production efficiency.

[0036] like Figure 4 and Figure 5 As shown, a buffer groove 303b is further provided on the turning plate 3 at the bottom corner of the material receiving trough 303a, and the buffer groove 303b is arranged along the width direction of the material receiving trough 303a. When the wood to be processed falls into the material receiving trough 303a under the action of gravity, the wood to be processed will slide along the bottom wall of the material receiving trough 303a, and the corner below it will collide with the corner of the material receiving trough 303a. Through the design of the buffer groove 303b, the impact on the corner below the wood to be processed can be avoided, thereby protecting the wood to be processed and avoiding damage to the wood to be processed.

[0037] like Figure 1 , such as 2, Figure 4 and Figure 5As shown, the side wall of the material turning plate 3 has petals with the same number as the material receiving groove 303a. It can be understood that the petals are convex structures extending from the side wall of the material turning plate 3 to the lateral space, and the material receiving groove 303a is arranged on the petals, and the buffer groove 303b connected thereto is also arranged on the petals. Specifically, the material receiving groove 303a is connected with any side wall and upper end surface of the petals, that is, the material receiving groove 303a has an open-closed structure with one end closed, so as to facilitate the wood to be processed that is separated from the conveyor belt 2 to enter the material receiving groove 303a, and at the same time, the wood to be processed that enters the material receiving groove 303a can be supported by the closed end and bottom wall of the material receiving groove 303a. It should be mentioned that there are multiple petals, each of which is spaced apart and arranged on the side wall of the turning plate 3, so that the turning plate 3 can continuously receive the wood to be processed that has separated from the conveyor belt 2 during rotation, without waiting for the petals to be reset, so that the processing efficiency is significantly improved. After the wood is milled into a wooden workpiece by the cutter disc 4, since the cutter disc 4 is located below the turning plate 3, as the turning plate 3 continues to rotate upward, when the opening of the receiving groove 303a is opposite to the bottom surface, the wooden workpiece located in the receiving groove 303a can automatically fall down under the action of gravity and separate from the turning plate 3, so as to facilitate the collection of the wooden workpiece.

[0038] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the turning plate 3 includes an inner plate body 301, a central plate body and an outer plate body 303, the inner plate body 301 is connected to the output end of the electric drive box 5, the central plate body 302 and the outer plate body 303 are overlapped and mounted outside the inner plate body 301, the lobes include a first lobes 302a and a second lobes 303c, the first lobes 302a and the second lobes 303c are equal in number and opposite to each other, and are respectively formed on the central plate body 302 and the outer plate body 303, the material receiving groove 303a is opened on the second lobes 303c, based on the above arrangement, the side of the material receiving groove 303a opened on the second lobes 303c away from the external space can be closed by the second lobes 303c, so that the wood to be processed can be supported laterally to avoid tipping over, thereby ensuring the regularity of the processing surface during processing.

[0039] like Figure 1 , Figure 2 and Figure 4 As shown, there are two outer discs 303, and the two outer discs 303 are arranged on both sides of the central disc 302. The second petal bulges 303c on the two outer discs 303 and the first petal bulges 302a on the central disc 302 remain opposite. It can be understood that each second petal bulge 303c has an adjacent second petal bulge 303c opposite to it, so that the turning disc 3 can receive two pieces of wood to be processed, and correspondingly, two pieces of wood can be milled at the same time. The above-mentioned double-station setting can further improve the processing efficiency of the profiling machine of the present invention.

[0040] like Figure 1 and Figure 2 As shown, the cutter disc 4 includes a first cutter body 401 and a second cutter body 402. The first cutter body 401 and the second cutter body 402 are spaced apart from each other up and down, and are both distributed on the rotation path of the turning plate 3 and are tangent to or separated from the turning plate 3. The first cutter body 401 and the second cutter body 402 are respectively used for rough milling and fine milling of wood, ensuring the regularity of the processed surface of the final wooden workpiece and improving the quality of the wooden workpiece.

[0041] like Figure 1 and Figure 2 As shown, it also includes a collection box 6, which is arranged below the turning plate 3, and its opening is opposite to the turning plate 3, so that the processed wooden workpieces can be directly collected without the need for operators to collect them one by one.

[0042] Combination Figures 1 to 6 The present invention also provides a wood processing method using the above-mentioned wood workpiece profiling device, which comprises the following steps:

[0043] S1: Put the wood to be processed into the feed box 1, and adjust the direction and sort the wood to be processed by the vibration of the feed box 1 which is a vibration plate, so that the wood to be processed is divided into two columns, and then synchronously transported to the conveyor belt 2;

[0044] S2: The two rows of wood to be processed that arrive at the conveyor belt 2 are continuously transported toward the turning plate 3 on both sides of the diverter block 203 of the conveyor belt 2;

[0045] S3: The wood to be processed passing through the conveyor belt 2 falls into the receiving groove 303a of the turning plate 3 controlled by the electric drive box 5 to rotate vertically in sequence under the action of gravity. The wood to be processed is supported by the inner wall of the receiving groove 303a and can be stably kept in the receiving groove 303a.

[0046] S4: The turning plate 3 drives the wood to be processed in the receiving groove 303a thereof to rotate on a plane perpendicular to the horizontal plane, and passes through the cutter head 4 which is controlled by the electric drive box 5 and rotates in the opposite direction to the wood to be processed. The first cutter body 401 included in the cutter head 4 performs rough milling on the wood to be processed, and the second cutter body 402 performs fine milling on the wood to obtain a wooden workpiece;

[0047] S5: With the continuous rotation of the turning plate 3, when the opening of the receiving groove 303a is opposite to the ground, under the action of gravity, the wooden workpieces fall into the collecting box 6 below and are uniformly collected.

[0048] The above embodiments and descriptions are only for illustrating the principles and best embodiments of the present invention. Without departing from the spirit and scope of the present invention, the present invention may be subject to various changes and improvements, all of which fall within the scope of the present invention to be protected.
