Description

Technical Field

[0001] The invention relates to wood processing technology, and in particular to a wood processing process and a processing device. Background Art

[0002] Wood has the advantages of light weight, good elasticity and impact resistance. It is widely used in construction, decoration, furniture and other fields. Wood processing technology includes basic processing technologies such as wood cutting, wood drying, wood gluing and wood surface decoration. Before wood cutting, it is usually necessary to peel the wood surface first; and the wood collected during wood processing is not only cut down in sparsely populated forests, but also from areas with more frequent human activities.

[0003] For example, the patent with the authorization announcement number CN115446941B and the authorization announcement date December 22, 2023, is entitled "A patent for an efficient wood surface treatment process and treatment device", which includes a U-shaped mounting plate, the interior of the mounting plate is provided with a fixing mechanism for fixing the wood, a peeling mechanism for peeling the wood, and a bark processing mechanism, wherein the peeling mechanism is located above the fixing mechanism, and the bark processing mechanism is located below the fixing mechanism; the peeling mechanism includes a first screw rod horizontally inserted into the inner wall of the mounting plate, a slider is threadedly sleeved on the outer side of the first screw rod, a guide rod is horizontally slidably inserted into the interior of the slider, the guide rod is fixedly connected to the inner wall of the mounting plate, the bottom end of the slider is connected to an inverted and U-shaped first blade through a second electric telescopic rod, and an arc-shaped second blade is fixed to the bottom end of the first blade; the present invention uses the bark processing mechanism to promptly crush the peeled bark, simplify the processing flow, and improve the processing efficiency.

[0004] Another example is a patent with the authorization announcement number CN116765958B and the authorization announcement date May 14, 2024, entitled "Fresh air heat exchanger and fresh air system", which includes a rotating support arm, a supporting fixed base, a first electric push rod, a limited support body and a cleaning body, wherein the first electric push rod is symmetrically fixedly mounted on the upper end of the supporting fixed base. The present invention can limit the support and limit the logs that need to be polished and trimmed by setting a polishing and peeling part, so that logs of different diameters can be supported and limited, and the logs can be driven to rotate 360° after the support and limitation. By setting a cleaning body, the logs that are supported and rotated can be quickly and fully peeled and trimmed, and the polishing and cleaning part in the cleaning body can perform reciprocating polishing and trimming along the rotating logs, so that the outer skin of the logs can be fully polished and trimmed, so that the trimmed logs are straight, the outer wall is neat, and it is convenient for processing and use.

[0005] The disadvantage of the prior art is that when peeling wood in areas with frequent human activities, there is a high probability that hard objects such as nails or wires will be inserted into the surface of the collected wood, and hard knots may be formed in the growth process of the wood, which can easily damage the moving cutter during peeling and reduce the service life of the cutter. Summary of the invention

[0006] The object of the present invention is to provide a wood processing technology and a processing device to solve the above-mentioned deficiencies in the prior art.

[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0033] like Figure 1-8As shown, a wood processing device provided by an embodiment of the present invention includes a wood conveying mechanism 1, on which a peeling mechanism 2 is fixed, and the peeling mechanism 2 includes an inner ring 21 rotatably arranged for passing wood, and a plurality of arc grooves 22 are circumferentially opened on the inner wall of the inner ring 21, and a moving part 24 is slidably connected in the arc groove 22 through a buffer spring 23, and a peeling cutter 26 is installed at the inner end of the moving part 24 through an external pulling unit 25; when the peeling cutter 26 collides with a hard object and is blocked, the moving part 24 slides in the arc groove 22 and moves relative to the inner ring 21, and when the moving part 24 contacts the end of the arc groove 22, the external pulling unit 25 drives the peeling cutter 26 to move outward.

[0034] Specifically in this embodiment, the wood conveying mechanism 1 is mainly used to convey cylindrical wood. The wood processed in this embodiment is also mainly cylindrical wood. The wood conveying mechanism 1 includes a plurality of conveying rollers, each two conveying rollers form a group, and the two conveying rollers in a group are respectively pressed and arranged on the upper and lower sides of the wood. The conveying rollers are in close contact with the wood and drive the wood forward by rotating. While driving the wood forward, the conveying rollers can also prevent the wood from rotating when peeling. The wood conveying mechanism 1 is a prior art and will not be described in detail here; the inner ring 21 is a ring structure And it has a certain thickness, the arc groove 22 is an arc structure with a large interior but a small mouth, the central axis of the arc groove 22 coincides with the central axis of the inner ring 21, preferably, a plurality of the arc grooves 22 are evenly arranged in the circumferential direction, the moving part 24 is an arc-shaped plate-like structure as a whole and is slidably arranged in the arc groove 22, the central axis of the moving part 24 coincides with the central axis of the arc groove 22, in the initial state, the moving part 24 can completely cover the mouth of the arc groove 22, and the moving part 24 can still completely cover the mouth of the arc groove 22 when moving, so as to avoid wood chips The peeling cutter 26 and the inner ring 21 are connected to each other by the buffer spring 23, and the movable part 24 is slidably connected in the arc groove 22 by the buffer spring 23. The buffer spring 23 is used to maintain the initial position of the movable part 24, so that the movable part 24 can move in the arc groove 22. In the initial state, under the elastic action of the buffer spring 23, there is a certain distance between the peeling cutter 26 and the end of the arc groove 22, so that the peeling cutter 26 and the inner ring 21 can move relative to each other. Preferably, the peeling cutter 26 is located in the middle of the movable part 24, and the connecting section 261 is connected to the outer pulling unit 25. The cutting section 262 is perpendicular to the inner end of the connecting section 261, and the cutting section 262 is mainly used to cut the outer skin of the wood and avoid hard objects when moving outward; it should be noted that in the normal peeling process, the inner ring 21 drives the moving part 24 to move by driving the buffer spring 23, and the peeling cutter 26 will also be subject to a certain resistance in the normal peeling process, which will squeeze the buffer spring 23 and drive the moving part 24 to move relative to the inner ring 21, but the relative movement will not cause the outer pulling unit 25 to contact the side wall of the arc groove 22;The peeling cutter 26 is connected to the movable part 24 through the outer pulling unit 25. The outer pulling unit 25 is mainly used to drive the peeling cutter 26 to move axially outward when the peeling cutter 26 is blocked, and the outer pulling unit 25 is passively triggered. Only when the outer pulling unit 25 begins to contact the side wall of the arc groove 22, the outer pulling unit 25 begins to be triggered. In this embodiment, the peeling cutter 26 has two working positions. In the first working position, the peeling cutter 26 is in a normal working state and does not move outward. At this time, the inner ring 21 rotates normally, and the peeling cutter 26 performs the peeling work normally. In the second working position, the peeling cutter 26 encounters a hard object and is blocked. At this time, the movable part 24 cannot continue to move, but the inner ring The ring 21 is still rotating, so the inner ring 21 and the moving part 24 move relative to each other and squeeze the buffer spring 23. When the moving part 24 contacts the end of the arc groove 22, the outer pull unit 25 is driven to move the peeling cutter 26 outward. In this way, when the peeling cutter 26 encounters a nail or other hard object such as a tumor, the inner ring 21 and the peeling cutter 26 move relative to each other, and the movement of the peeling cutter 26 is protected by the buffer spring 23. When the outer pull unit 25 starts to contact the side wall of the arc groove 22, the outer pull unit 25 is driven to move the peeling cutter 26 outward. In this way, not only can the peeling cutter 26 be protected from damage, but also hard objects can be avoided outward to avoid affecting the subsequent peeling work. ;

[0035] In another embodiment provided by the present invention, the peeling mechanism 2 includes a working box 27 fixedly mounted on the wood conveying mechanism 1, a through opening is opened at the bottom of the working box 27, and a feed port and a discharge port are opened at opposite ends of the working box 27, the feed port and the discharge port are both circular, the feed port is used for the entry of wood, and the discharge port is used for outputting the peeled wood, the working box 27 can prevent the peeled wood chips from flying around, and the peeled wood chips can fall out from the through opening.

[0036] In another embodiment provided by the present invention, a limiting bracket 271 is fixedly connected to the working box 27, and an annular limiting plate 272 is formed on the outer wall of the inner ring 21. The axial cross-section of the annular limiting plate 272 is preferably T-shaped, and the annular limiting plate 272 is slidably installed on a plurality of limiting brackets 271. In this way, the inner ring 21 is rotationally limited so that the inner ring 21 can rotate along its central axis.

[0037] In another embodiment provided by the present invention, it also includes a driving unit, which is used to drive the inner ring 21 to rotate; the driving unit includes an outer gear ring 281 formed in the middle of the outer side wall of the inner ring 21, and a driving gear 282 is rotatably installed in the working box 27, and the driving gear 282 is meshed with the outer gear ring 281. A driving motor 283 is also installed in the working box 27, and the output shaft of the driving motor 283 is connected to the center of the driving gear 282; when the driving motor 283 is started, it drives the driving gear 282 to rotate, and the outer gear ring 281 is driven to rotate through the driving gear 282. Since the inner ring 21 is rotationally limited by the annular limiting plate 272 and the limiting bracket 271, the inner ring 21 can rotate, thereby driving the inner ring 21 to rotate so that the peeling cutter 26 peels the wood.

[0038] In another embodiment provided by the present invention, the peeling cutter 26 is an L-shaped structure, and the peeling cutter 26 consists of a connecting section 261 and a cutting section 262. The extension direction of the connecting section 261 passes through the central axis of the inner ring 21. The connecting section 261 is connected to the outer pulling unit 25, and the cutting section 262 is perpendicular to the inner end of the connecting section 261. The cutting section 262 is mainly used to cut the outer bark of the wood.

[0039] In another embodiment provided by the present invention, the arc groove 22 includes a first arc groove 221 and a second arc groove 222 that are interconnected, the first arc groove 221 is opened in the inner ring 21, the second arc groove 222 passes through the inner wall of the inner ring 21, the angle occupied by the first arc groove 221 is greater than that of the second arc groove 222, and the size of the first arc groove 221 is greater than that of the second arc groove 222, so as to limit the moving part 24 so that it can only slide in the first arc groove 221; the moving part 24 is slidably installed in the first arc groove 221, and the inner end of the moving part 24 is attached to the inner end of the first arc groove 221, and the size of the moving part 24 is greater than that of the second arc groove 222, mainly to prevent wood chips and the like from entering the first arc groove 221.

[0040] In another embodiment provided by the present invention, the external pulling unit 25 includes a mounting frame 251 fixed to the inner end of the moving part 24, and a mounting cavity is formed in the mounting frame 251. Two limiting support plates 252 are slidably penetrated at the inner end of the mounting frame 251, and a peeling cutter 26 is fixed between the inner ends of the limiting support plates 252. A driving rod 253 is fixed to the outer end of the limiting support plates 252. An elastic pressure rod 254 is slidably penetrated on the side wall of the mounting frame 251. The elastic pressure rod 254 is preferably a cylinder. The elastic pressure rod 254 and the side wall of the second arc groove 222 are correspondingly arranged. When When the inner ring 21 and the peeling cutter 26 move relative to each other, the elastic pressure rod 254 will be squeezed onto the side wall of the second arc groove 222. A limiting spring 255 is connected between the elastic pressure rod 254 and the outer wall of the mounting frame 251. A trapezoidal driving block 256 is fixed on one end of the elastic pressure rod 254 located in the mounting cavity. A driving groove is provided on the inclined surface of the trapezoidal driving block 256. The end of the driving rod 253 is slidably installed in the driving groove and forms a wedge-shaped fit. When the trapezoidal driving block 256 moves toward the direction close to the driving rod 253, the inclined surface of the trapezoidal driving block 256 will squeeze the driving rod 253 to move outward.

[0041] When the peeling cutter 26 encounters a hard object, the movement of the peeling cutter 26 is blocked. At this time, the moving part 24 and the inner ring 21 move relative to each other. Relative to the moving part 24, the inner ring 21 continues to move and makes the first arc groove 221 and the second arc groove 222 move synchronously. When the side wall of the second arc groove 222 contacts the elastic pressure rod 254, the inner ring 21 continues to move to squeeze the elastic pressure rod 254, and the elastic pressure rod 254 moves into the installation cavity and pushes the trapezoidal driving block 256 to move. At this time, the trapezoidal driving block 256 and the driving groove move synchronously and squeeze the driving rod 253 to rise along the inclined surface of the trapezoidal driving block 256. In this way, the limiting support plate 252 also moves outward synchronously, and the peeling cutter 26 is driven to move outward to avoid the hard object through the limiting support plate 252; through the above technical scheme, the relative movement between the moving part 24 and the inner ring 21 is utilized to make the peeling cutter 26 passively move upward to avoid the hard object after encountering a hard object.

[0042] For further information, see Figure 7-8When the peeling cutter 26 encounters a hard object (such as a nail, etc.), it is generally necessary to stop the machine and remove the hard object manually, which will reduce the peeling efficiency. For this reason, the present embodiment provides a further solution by further improving the peeling cutter 26. The end of the cutting section 262 (the end used for peeling) is evenly provided with a plurality of tooth grooves 263, and the tooth grooves 263 are approximately triangular. The tooth grooves 263 are mainly used to clamp hard objects of different diameters (sizes) therein, so as to facilitate the separation of the hard objects when the peeling cutter 26 leaves. When the hard object contacts the peeling cutter 26, it will enter the tooth groove 263 along the inclined surface on the tooth groove 263. When the hard object is completely stuck in the tooth groove 263, the inner ring 21 and the moving part 24 begin to move relative to each other and make the peeling cutter 26 move outward through the external pulling unit 25 to pull the hard object. In this way, the hard object can be separated from the wood.

[0043] Further, see Figure 7-8After the hard object is pulled out through the tooth groove 263, the hard object may still be stuck in the tooth groove 263. Therefore, this embodiment provides a further technical solution to solve the above technical problems. A movable groove 264 is provided in the middle of the connecting section 261. An extrusion rod 265 is slidably installed in the movable groove 264. The inner end of the extrusion rod 265 is provided with an inclined surface. The outer end of the extrusion rod 265 extends to the outside of the connecting section 261. There is a certain distance between the outer end surface of the extrusion rod 265 and the installation frame 251. The extrusion rod 265 and the installation frame 251 are correspondingly arranged. A connecting rod 264 is also provided in the cutting section 262. The connecting groove 266, one end of the connecting groove 266 is connected to the movable groove 264, and the connecting groove 266 is perpendicular to the movable groove 264, the other end of the movable groove 264 is connected to the tooth groove 263, and an ejection block 267 is slidably installed in the movable groove 264, and a mounting spring 268 is connected between the ejection block 267 and the movable groove 264. In the initial state, under the action of the gravity of the extrusion rod 265 and the elastic action of the mounting spring 268, the inclined surface on the extrusion rod 265 fits on the ejection block 267; specifically, when working, when the hard object is completely stuck in the tooth groove 263, the inner ring 21 and the movable part 2 4 begins to move relative to each other. At this time, the elastic pressure rod 254 gradually approaches the side wall of the second arc groove 222. When the elastic pressure rod 254 contacts the side wall of the second arc groove 222, the connecting section 261 starts to move upward, and the squeezing rod 265 and the cutting section 262 are driven to move upward synchronously through the connecting section 261, and the hard object is pulled out through the tooth groove 263 on the cutting section 262. However, the elastic pressure rod 254 has not moved to the limit state at this time, that is, the elastic pressure rod 254 can continue to be squeezed. In this way, when the spring pressure rod continues to move, the connecting section 261 continues to move upward so that the squeezing rod 265 and the mounting frame 251 are aligned with each other. The extrusion rod 265 is blocked by the mounting frame 251 and slides in the movable groove 264. The ejection block 267 is squeezed by the inclined surface on the extrusion rod 265 to make the ejection block 267 move out of the connecting groove 266. At the same time, the mounting spring 268 is stretched, so that the ejection block 267 enters the tooth groove 263 and ejects the hard object in the tooth groove 263. Through the above technical solution, the relative movement between the connecting section 261 and the mounting frame 251 is utilized to passively drive the extrusion rod 265 to move so that the ejection block 267 moves synchronously to eject the hard object out of the tooth groove 263, and other waste materials in the tooth groove 263 can also be removed.

[0044] In another embodiment provided by the present invention, a wood processing process is provided, which is based on the above-mentioned wood processing device, and the specific method is:

[0045] When the wood passes through the inner ring 21, the peeling cutter 26 is driven by the rotating inner ring 21 to move and peel the wood. When the peeling cutter 26 encounters an iron nail, the movement of the peeling cutter 26 is blocked and the moving part 24 is caused to slide relatively in the arc groove 22, and the movement of the peeling cutter 26 is buffered by the buffer spring 23.

[0046] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
