Description

Technical Field

[0001] This utility model relates to the field of wood processing technology, specifically to a peeling device for wood processing. Background Technology

[0002] A wood peeling device is a specialized piece of equipment that removes the bark from the surface of logs or logs using mechanical force (such as friction, compression, or cutting). Its core function is to pre-treat the wood for subsequent cutting, drying, and processing into boards or finished products.

[0003] For example, a wood peeling device with authorization publication number "CN118238243A" uses a C-shaped support and connecting seat to allow the wood to rest inside them. By rotating the connecting seat at a certain angle, and with the support of two threaded sleeves, the stability of the wood during the peeling process can be ensured. Traditional double-roller peeling equipment uses a double-sided single-point clamping structure, which can only clamp the wood through the radial force of the two rollers. When the wood is rotated for peeling, the radial clamping force cannot restrain its unstable axial and circumferential displacement. Due to the roundness deviation of the wood itself or the uneven adhesion of the bark, it will move up and down and shift left and right, resulting in poor adhesion between the roller surface and the wood. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the two rollers can only form a single-point clamping from both sides, and the wood will shift due to uneven force when rotating and peeling. Therefore, a peeling device for wood processing is proposed.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a wood peeling device, including a base and vertical plates. Vertical plates are fixedly connected to the left and right sides of the upper end of the base. Two sliding rods are fixedly connected to the inner end of the vertical plates. The outer walls of the sliding rods are slidably connected to protrusions processed on the front and rear sides of a square plate. A single roller is provided at the upper end of the square plate to clamp and peel the wood. A double roller is provided on the left side of the upper end of the base to clamp and convey the wood.

[0007] This feature allows the sliding rod to limit and support the counter plate.

[0008] Preferably, the single-roller clamping peeling structure includes a straight plate, two straight plates are fixedly connected to the upper end of the square plate, the front end of the front straight plate is threadedly connected to the first servo motor by bolts, the output shaft of the first servo motor is fixedly connected to the first circular roller, both ends of the first circular roller are rotatably connected to the straight plate by sealed bearings, and multiple inclined plates are fixedly connected to the left end of the square plate.

[0009] This setting ensures that the rotation direction of the first roller is the same as that of the second roller on the lower side. This rotation direction can form a "cooperative force in the horizontal direction" with the lower roller on the left side. With the support of the inclined plate, it further stabilizes the rotation trajectory of the wood and ensures that small pieces of bark are scraped off the outer wall of the roller.

[0010] Preferably, two electric telescopic rods are fixedly connected to the left end of the vertical plate on the right.

[0011] This electric telescopic pole features a self-locking function.

[0012] Preferably, the output ends of the electric telescopic rods are all fixedly connected to the cross plate.

[0013] Preferably, the left end of the horizontal plate is fixedly connected to the square plate.

[0014] Preferably, the double-roller clamping and conveying structure includes vertical blocks. Two vertical blocks are fixedly connected to the upper left side of the base. The outer wall of the front vertical block is threadedly connected to the second servo motor by bolts. The output shaft of the second servo motor is fixedly connected to the first gear. The outer wall of the first gear is meshed with the second gear. The rotation shafts of the first gear and the second gear are both fixedly connected to the second roller. Both ends of the second roller are rotatably connected to the vertical blocks through sealed bearings.

[0015] The two second rollers in this configuration rotate in opposite directions and are very close together. This close-fitting, opposite rotation creates a "compression friction" that firmly grips the wood, providing it with core rotational power while preventing the wood from shifting in the vertical direction.

[0016] The present invention proposes a wood peeling device with the following advantages: Through the cooperation of a single-roller clamping peeling structure and a double-roller clamping conveying structure, the output shaft of the second servo motor drives the first gear to rotate, simultaneously constraining the vertical displacement of the wood and preventing it from shifting up and down. The wood, conveyed by the two second rollers, gradually enters the working area between the first and second rollers until the lower end of the wood contacts multiple inclined plates fixed to the left end of the square plate. The inclined plates support the wood, preventing axial displacement. Combined with the supporting force of the inclined plates, the wood is constrained from both horizontal and vertical directions, thus avoiding the circumferential and axial displacement problems caused by traditional equipment relying solely on radial clamping force. Simultaneously, dotted protrusions are machined on the outer walls of both the first and second rollers. During rotation, these protrusions rub against the bark, scraping off the bark mechanically. Under the synergistic effect of continuous conveying by the double-roller clamping conveying structure and stable peeling by the single-roller clamping peeling structure, the bark is continuously peeled off. This method prevents the wood from shifting during peeling. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] See attached document Figure 1-6 In this embodiment, a wood peeling device includes a base 1 and a vertical plate 2. The vertical plate 2 is fixedly connected to the left and right sides of the upper end of the base 1, and the base 1 provides support for the vertical plate 2. Two sliding rods 3 are fixedly connected to the inner end of the vertical plate 2, and the vertical plate 2 provides support for the sliding rods 3. The outer wall of the sliding rod 3 is slidably connected to the protrusions processed on the front and rear sides of the square plate 4. The square plate 4 slides on the sliding rod 3 through the protrusions processed on the front and rear sides. The sliding rod 3 plays the role of limiting and sliding support for the square plate 4. The upper end of the square plate 4 is provided with a single roller clamping peeling structure 5, and the upper left side of the base 1 is provided with a double roller clamping conveying structure 6.

[0026] Two electric telescopic rods 7 are fixedly connected to the left end of the right vertical plate 2. The electric telescopic rods 7 have a self-locking function. The electric telescopic rods 7 are connected to an external power supply (not marked in the figure) and are equipped with control buttons and circuit systems for starting and stopping the electric telescopic rods 7. The two electric telescopic rods 7 are connected to a PLC controller. Through programming and other operations, the two electric telescopic rods 7 can be started simultaneously. The output ends of the electric telescopic rods 7 are fixedly connected to the horizontal plate 8. The left end of the horizontal plate 8 is fixedly connected to the square plate 4. The movement of the horizontal plate 8 moves the square plate 4.

[0027] See attached document Figure 1-3The single-roller clamping peeling structure 5 includes a straight plate 501. Two straight plates 501 are fixedly connected to the upper end of a square plate 4. The square plate 4 provides support for the straight plates 501. The front end of the front straight plate 501 is threadedly connected to the first servo motor 502 by bolts. The first servo motor 502 is mounted on the front straight plate 501 by bolts. The first servo motor 502 has a self-locking function. The first servo motor 502 is externally connected to a power supply (not marked in the figure) and is equipped with control buttons and a circuit system for starting and stopping the first servo motor 502.

[0028] The output shaft of the first servo motor 502 is fixedly connected to the first roller 503. Both ends of the first roller 503 are rotatably connected to the straight plate 501 through sealed bearings. The first roller 503 rotates inside the straight plate 501 through the sealed bearings. Multiple inclined plates 504 are fixedly connected to the left end of the square plate 4. The inclined plates 504 provide support. Multiple dot-shaped protrusions are processed on the outer wall of the first roller 501. The small dots can enhance the friction with the bark, easily peel off the bark, and the small dot contact area makes it less likely to scratch the surface of the wood.

[0029] The output shaft of the first servo motor 502 drives the first roller 503 to rotate. The rotation direction of the first roller 503 is the same as the rotation direction of the second roller 605 on the lower side of the double roller clamping and conveying structure 6. The two work together to form a horizontal synergistic force. Combined with the supporting force of the inclined plate 504, the wood is constrained from both the horizontal and vertical directions, thus avoiding the circumferential and axial offset problems caused by the radial clamping force of traditional equipment. At the same time, the outer walls of the first roller 503 and the second roller 605 are processed with dot-shaped protrusions. When rotating, the protrusions rub against the bark and scrape off the bark by mechanical force. Under the synergistic effect of the continuous conveying of the double roller clamping and conveying structure 6 and the stable peeling of the single roller clamping and peeling structure 5, the bark is continuously peeled off.

[0030] See attached document Figure 1-6 The double-roller clamping conveyor structure 6 includes vertical blocks 601. Two vertical blocks 601 are fixedly connected to the upper left side of the base 1. The base 1 provides support for the vertical blocks 601. The outer wall of the front vertical block 601 is threadedly connected to the second servo motor 602 by bolts. The second servo motor 602 is mounted on the vertical block 601 by bolts. The second servo motor 602 is externally connected to a power supply (not marked in the figure) and is equipped with control buttons and a circuit system for starting and stopping the second servo motor 602. The output shaft of the second servo motor 602 is fixedly connected to the first gear 603.

[0031] The outer wall of the first gear 603 meshes with the second gear 604. The two gears rotate in opposite directions. The rotation shafts of the first gear 603 and the second gear 604 are both fixedly connected to the second roller 605. Both ends of the second roller 605 are rotatably connected to the vertical block 601 through sealed bearings. The second roller 605 rotates inside the vertical block 601 through the sealed bearings. The outer wall of the second roller 605 is processed with multiple dot-shaped protrusions. The small dots can enhance the friction with the bark, making it easy to peel off the bark. Moreover, the dot-shaped contact area is small, making it less likely to scratch the surface of the wood.

[0032] The output shaft of the second servo motor 602 drives the first gear 603 to rotate. Due to the gear meshing transmission characteristics, the first gear 603 and the second gear 604 rotate in opposite directions. Since the rotating shafts of both gears are fixedly connected to the second roller 605, and the two ends of the second roller 605 are rotatably connected to the vertical block 601 through sealed bearings, the two second rollers 605 rotate synchronously in opposite directions with the gears. Since the distance between the two second rollers 605 is extremely small, a squeezing friction force is generated when they rotate in opposite directions, which firmly grips the wood and provides the wood with the power to move in the direction of the single roller clamping and peeling structure 5. At the same time, it constrains the vertical displacement of the wood and prevents it from moving up and down. Under the conveying of the two second rollers 605, the wood gradually enters the working area between the first roller 503 and the second roller 605 until the lower end of the wood contacts the multiple inclined plates 504 fixed on the left end of the square plate 4. The inclined plates 504 support the wood, complete the wood positioning, and prevent its axial displacement.

[0033] Working principle:

[0034] When using a wood peeling device:

[0035] Activate the two electric telescopic rods 7 fixed to the left end of the right vertical plate 2. The output ends of the two electric telescopic rods 7 push the horizontal plate 8. The left end of the horizontal plate 8 is fixedly connected to the square plate 4, which drives the square plate 4 to slide along the two sliding rods 3 fixed to the inner end of the vertical plate 2. The single roller at the upper end of the square plate 4 cooperates with the peeling structure 5 to move synchronously with the square plate 4 until the first round roller 503 in the single roller cooperating with the peeling structure 5 and the two second round rollers 605 in the double roller clamping and conveying structure 6 form an initial gap that matches the diameter of the wood. After the adjustment is completed, the electric telescopic rods 7 self-lock, locking the position of the square plate 4 to prevent displacement in subsequent work.

[0036] The wood to be peeled is placed between the two second rollers 605. The external power supply to the second servo motor 602 is connected, and the second servo motor 602 is started. The output shaft of the second servo motor 602 drives the first gear 603 to rotate. Due to the gear meshing transmission characteristics, the first gear 603 and the second gear 604 rotate in opposite directions. Since the rotating shafts of both gears are fixedly connected to the second rollers 605, and both ends of the second rollers 605 are rotatably connected to the vertical block 601 through sealed bearings, the two second rollers 605 rotate synchronously in opposite directions with the gears. The rollers 605 have a very small gap (close to each other). When they rotate in the opposite direction, they generate a squeezing friction force, which firmly grips the wood and provides the wood with the power to move in the direction of the single roller clamping and peeling structure 5. At the same time, it restricts the vertical displacement of the wood and prevents it from moving up and down. Under the conveying of the two second rollers 605, the wood gradually enters the working area between the first roller 503 and the second roller 605 until the lower end of the wood contacts the multiple inclined plates 504 fixed on the left end of the square plate 4. The inclined plates 504 support the wood, complete the wood positioning, and prevent its axial displacement.

[0037] When the external power supply of the first servo motor 502 is connected and the first servo motor 502 is started, the output shaft of the first servo motor 502 drives the first circular roller 503 to rotate. The rotation direction of the first circular roller 503 is consistent with the rotation direction of the second circular roller 605 on the lower side of the double roller clamping and conveying structure 6. The two work together to form a horizontal synergistic force, which, combined with the supporting force of the inclined plate 504, constrains the wood from both horizontal and vertical directions. This avoids the circumferential and axial offset problems caused by traditional equipment relying solely on radial clamping force. At the same time, the outer walls of both the first circular roller 503 and the second circular roller 605 are machined with dot-shaped protrusions (such as... Figure 4 As it rotates, the protrusions rub against the bark, scraping it off mechanically. With the continuous conveying of the double-roller clamping conveyor structure 6 and the stable peeling of the single-roller clamping peeling structure 5, the bark is continuously peeled off. The peeled wood eventually slides down the inclined plate 504, and the entire process ends.

[0038] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
