Description

Technical Field

[0001] The present invention belongs to the technical field of plate stacking, and in particular to an intelligent identification, sorting and stacking device for quality grading of log peeled veneers. Background Art

[0002] After the peeled veneers are processed, they need to be transported by conveyor belts and quality tested during the transportation process. It is understandable that if there are unqualified peeled veneers in the process, they can be rejected in real time. At the end of the conveyor belts, the peeled veneers that have passed the quality inspection are stacked and placed. When a certain number is reached, they are transported and stored by forklifts.

[0003] A Chinese patent with publication number CN113023376B discloses a plate stacking device, including several first frames, several second frames, several first rectangular tube racks, several second rectangular tube racks, several third frames and several fourth frames. The adjacent surfaces of the first frames are fixedly connected with a first crossbeam. By using an L-shaped frame, a first support frame, a drive frame, a second support frame and a photoelectric sensor, the device can stack plates in sequence from bottom to top, and then the photoelectric sensor can detect whether plates are stacked on each layer and send a signal; the present invention uses a first frame, a second frame, a third frame and a fourth frame. Since the first frame and the second frame can slide with each other, and the third frame and the fourth frame can also slide relative to each other, and then locked with screws, the distance between them is changed, so that the device can stack plates of larger sizes.

[0004] In the existing technology, the stacking and storage of plates can be realized by simply relying on L-shaped frames to support the plates. However, when applied to the field of sorting and stacking of peeled veneers, in order to further improve efficiency and reduce manual operation steps, the peeled veneers are directly delivered to the surface of the stacking platform at the end of the conveyor belt, and then automatically stacked with hydraulic equipment. However, on this basis, there may be a problem of tilting. If the veneers are directly driven to stack without correction, they may get stuck or cause scratches on the products themselves.

[0005] To this end, the present invention provides an intelligent identification, sorting and stacking device for quality grading of log peeled veneers. Summary of the Invention

DETAILED DESCRIPTION

[0037] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0038] like Figures 1 to 3 As shown, an intelligent identification, sorting and stacking device for quality grading of log peeled veneers according to an embodiment of the present invention includes a stacking module arranged at the end of a conveyor belt; the stacking module includes a base 10, a hydraulic cylinder 20, a limiter and side plates 30 slidably connected to both ends of the base 10; the hydraulic cylinder 20 is fixedly connected to the base 10, and a supporting plate 21 is fixedly connected to the output end; the limiter is movably connected to the side plate 30 for stacking the peeled veneers The stopper includes a rotating shaft 31, which is rotatably connected to the middle of the side plate 30. A bottom support plate 33 is fixed to the middle of the rotating shaft 31. A stopper 32 is also connected to the middle of the side plate 30. The stopper 32 is used to limit the direction in which the bottom support plate 33 deflects along with the rotating shaft 31. When the peeled veneer breaks through the bottom support plate 33 from bottom to top and is received by the bottom support plate 33, the stopper 32 limits the deflection of the bottom support plate 33, thereby supporting the peeled veneer in the middle of the side plate 30.

[0039] A correction unit is also provided on the inner side of the side panel 30, and a fixing frame 40 is provided at the bottom of the correction unit, and the correction unit is fixedly connected to the inner side of the side panel 30 via the fixing frame 40; two groups of correction units are provided, and are symmetrically arranged on the inner sides of the two side panels 30; the correction unit includes an outer slide rail 41, a slider 42 and a rope 46; the outer slide rail 41 is fixed to the top of the fixing frame 40, and the slider 42 is slidably connected to the inside of the outer slide rail 41. When the supporting plate 21 moves upward, the slider 42 is driven by the rope 46 to slide inside the outer slide rail 41 to perform horizontal correction on the rotary cut veneer.

[0040] When the peeled veneer is delivered to the stacking platform at the end of the conveyor belt, it may tilt. If it is directly stacked without correcting the tilt, it may get stuck or cause scratches on the product itself.

[0041] Based on the above, in one embodiment of the present invention, there is no need to deliberately transfer the peeled veneer on the conveyor belt to the surface of the support plate 21. By utilizing the acceleration of the conveyor belt combined with the gravity of the peeled veneer itself, when the peeled veneer is separated from the conveyor belt, it can freely fall to the surface of the support plate 21. There may be a problem of tilting. At this time, the support plate 21 moves up, and the rope 46 is used to tighten the slider 42 so that the slider 42 slides in the outer slide rail 41. When the slider 42 slides from the side plate 30 toward the support plate 21, the symmetrically arranged correction units can be used The ropes 46 of equal length pull the two sliders 42, causing the two sliders 42 to move synchronously by the same distance, thereby correcting the offset peeled veneer and aligning the center line of the peeled veneer with the center line of the support plate 21. As a result, when the support plate 21 further drives the peeled veneer after the correction to move up and contact the bottom support plate 33, the positions of the two ends of the peeled veneer contacting the two bottom support plates 33 are as symmetrical as possible, keeping the peeled veneer in a horizontal state when sliding with the bottom support plate 33 until the peeled veneer squeezes the bottom support plate 33 and deflects a large angle. At this time, the side edge of the peeled veneer is aligned with the bottom support plate 33. The bottom surface of the bottom support plate 33 is almost vertical. At this time, the support plate 21 continues to press the peeled veneer upward, and the peeled veneer is able to break through the bottom support plate 33. Then the support plate 21 contracts downward, and the peeled veneer falls onto the reset surface of the bottom support plate 33 under the action of gravity and is received by the bottom support plate 33. In the above process, the peeled veneer is first received by the support plate 21, and moves upward with the support plate 21 until it contacts the bottom support plate 33, and then slides with the bottom support plate 33 and is received by the bottom support plate 33, corresponding to the feeding and temporary storage action of the peeled veneer. Among them, it is worth noting that It should be noted that the bottom support plate 33 and the rotating shaft 31 are fixedly connected by splines, and a torsion spring is arranged between the end of the rotating shaft 31 and the side plate 30, which can drive the bottom support plate 33 to reset after the bottom support plate 33 is passively deflected by a large angle. Cooperating with the support rod 32, the bottom support plate 33 can be kept in a horizontal state after reset, thereby realizing the temporary storage function of the peeled veneer. After a certain number of peeled veneers are stored on the bottom support plate 33, the batch of peeled veneers is transferred to other locations by a forklift, such as to a pallet, and then the pallet is lifted by the forklift to the storage area for long-term storage.

[0042] like Figures 1 to 2 As shown, a limiting rod 22 is slidably connected to the supporting plate 21, and the limiting rod 22 is an L-shaped structure.

[0043] In the above description, when the peeled veneer is transferred to the support plate 21 by the conveyor belt, it utilizes its own gravity and the acceleration applied by the conveyor belt. Therefore, the peeled veneer may not fall accurately onto the surface of the support plate 21, thereby causing deviation or slipping from the support plate 21. In this embodiment, only a sliding limit rod 22 is provided in the support plate 21, and the limit rod 22 is provided with an L-shaped structure. The direction of the bent end is defined as the discharge direction of the peeled veneer, and the direction of the parallel end is defined as the discharge direction of the peeled veneer. The feeding direction of the board, that is, when the peeled veneer is transferred from the conveyor belt to the supporting plate 21, the peeled veneer moves from the conveyor belt to the parallel end of the limit rod 22. If the acceleration is too large, it will also contact the bent end of the limit rod 22 and be limited by the bent end and cannot slip off. In addition, an elastic wire can be set between the supporting plate 21 and the bent end of the limit rod 22 to strengthen the connection between the limit rod 22 and the supporting plate 21. At the same time, when the peeled veneer causes an impact on the limit rod 22, a partial buffering effect is given.

[0044] like Figures 1 to 2 As shown, the middle part of the slider 42 is slidably connected to a slide rod 48 ; one end of the rope 46 is fixed to the bottom of the support plate 21 , and the other end passes through the end of the outer slide rail 41 and is fixed to one end of the slide rod 48 .

[0045] like Figures 1 to 7 As shown, a movable slot 481 is provided on the slide rod 48, and a swing arm 482 is hinged in the movable slot 481, an electromagnet is coaxially movably connected in the movable slot 481, and a support arm 483 is hinged at the output end of the electromagnet, one end of the support arm 483 is hinged to the output end of the electromagnet, and the other end is hinged to the middle of the swing arm 482. When the electromagnet is energized, the support arm 483 and the swing arm 482 are lifted synchronously. When the electromagnet is de-energized and retracted, the swing arm 482 and the support arm 483 are both retracted in the movable slot 481.

[0046] In the above embodiment, when the support plate 21 moves up, the rope 46 can be used to drive the slider 42 to slide inside the outer slide rail 41, so that the symmetrical and synchronous slider 42 can be used to correct the deviation of the peeled veneer. However, if the support plate 21 continues to move up, it may cause the slider 42 to move excessively, thereby causing squeezing or even deformation of the two ends of the peeled veneer. Therefore, the maximum displacement distance of the slider 42 should be limited. In one embodiment of the present invention, in the initial state, the electromagnet is energized and output, which can make the support arm 483 and the swing arm 482 rise synchronously, thereby making the other end of the slide rod 48 engage with the slider 42. When the rope 46 is pulled by the support plate 21, the slide rod 48 and the slider The slider 42 is engaged with each other, and can drive the slider 42 to slide in the outer slide rail 41. During the sliding process, the slider 42 contacts the offset peeled veneer, and under the action of the slider 42 that moves symmetrically and synchronously, the peeled veneer is successfully corrected. Thereafter, if the support plate 21 continues to move upward, the slider 42 is pulled by the rope 46, which will cause the side wall of the peeled veneer to be squeezed. At this time, the electromagnet is de-energized and retracted, and the swing arm 482 and the support arm 483 are retracted in the movable groove 481. The rope 46 is pulled by the support plate 21, which will transfer force to the slide bar 48, causing relative sliding between the slide bar 48 and the slider 42, and will not drive the slider 42 to continue to move, thereby squeezing the peeled veneer that has been corrected.

[0047] like Figures 1 to 2 As shown, a clearance hole 301 is opened on the side plate 30 , and the sliding rod 48 passes through the clearance hole 301 .

[0048] As mentioned above, since the outer slide rail 41 and the fixing frame 40 are both fixed to the inner side of the side panel 30, the sliding cooperation between the slide rod 48 and the slider 42 requires a larger displacement space. In one embodiment of the present invention, a clearance hole 301 is opened on the side panel 30 for the slide rod 48 to slide and pass through, thereby avoiding space affecting the implementation of the correction unit.

[0049] like Figures 1 to 4 As shown, the two ends of the slider 42 are slidably connected to the slide plate 43, and the slide plate 43 is slidably connected to the movable plate 431. When the force applied to the movable plate 431 is equal to the reaction force received, an electrical signal is generated to cut off the power to the electromagnet and retract.

[0050] In one embodiment, slide plates 43 are provided at both ends of the slider 42. When the slider 42 slides inside the outer slide rail 41 driven by the rope 46, the slide plates 43 can be used to contact and squeeze the peeled veneer, so that the peeled veneer is corrected. However, in this process, in order to prevent the slider 42 from being continuously displaced by the rope 46, an electromagnet is needed to control the movement of the swing arm 482 and the support arm 483. It can be understood that when the electromagnet is energized, the swing arm 482 and the support arm 483 are lifted, so that a snap-fitting relationship can be formed between the slide bar 48 and the slider 42. At this time, when the rope 46 is pulled, the slide bar 48 drives the slider 42 to displace. On the contrary, when the electromagnet is powered off and retracted, the swing arm 482 and the support arm 483 are retracted in the movable groove 481. At this time, the rope 46 is pulled, and the slide bar 48 will slide relative to the slider 42 and will not continue to drive the slider 42 to move. Based on the above, a movable plate 431 is set on the slide plate 43 at both ends of the slider 42. When the force on the movable plate 431 is analyzed, if the action force and the reaction force are equal, an electrical signal is generated, and the circuit of the electromagnet is automatically cut off through the electrical signal, so that the electromagnet is powered off and retracted. At this time, the support plate 21 pulls the rope 46 and cannot drive the slider 42 to continue to move, thereby avoiding squeezing the side wall of the rotary cut veneer.

[0051] like Figures 1 to 7 As shown, the middle part of the slider 42 is rotatably connected to two second gears 45, and the two second gears 45 are symmetrically distributed about the slider 42, and the two second gears 45 are engaged with the teeth on the outer wall of the slider 42; a second rack 47 is fixed to the outer side of the slide 43, and the second rack 47 is engaged with the second gear 45; when the rope 46 pulls the slider 42 to slide, the second gear 45 is engaged with the teeth on the slider 42 to rotate, and is engaged with the second rack 47, driving the second rack 47 and the slide 43 to slide on the slider 42.

[0052] Since the width of the peeled veneer is variable, the slide 43 in the fixed position may not be able to contact the peeled veneer during the sliding process of the slider 42, and thus cannot correct the peeled veneer. In one embodiment of the present invention, when the rope 46 pulls the slider 42 to slide in the outer slide rail 41, the second gear 45 on the slider 42 will mesh with the teeth on the outer side of the outer slide rail 41 and rotate under the meshing action. When the second gear 45 rotates, it can drive the second rack 47 meshed with it to slide. When the second rack 47 slides, it can drive the slide 43 to slide on the slider 42. Specifically, in the initial state, the slide 43 is located at the end position of the slider 42. In a correction unit, a slide 43 is provided at both ends of the slider 42, and a second rack 47 is fixed to the outer side wall of any slide 43. The two symmetrically arranged second gears 45 can mesh with the symmetrically arranged second rack 47, and at the same time drive the slide 43 to slide on the slider 42. It can be understood that Figure 3For example, when the rope 46 pulls the slider 42 to slide from the initial position to close to the support plate 21, the second gear 45 engages with the teeth on the outer slide rail 41, causing the second gear 45 to rotate, thereby driving the two second racks 47 to move toward each other, thereby driving the two slides 43 to move toward each other. Therefore, in the process of the rope 46 pulling the slider 42 to slide, the two slides 43 slide from the end of the slider 42 to the middle. At the same time, with the change in the position of the slider 42, the two slides 43 gradually approach the middle, so that they can adapt to peeled veneers of multiple widths and realize the correction of peeled veneers of multiple widths. It is worth noting that the two second racks 47 are staggered up and down, and correspondingly, the second gear 45 also has structural adaptive adjustments.

[0053] like Figures 1 to 7 As shown, a through hole 432 is opened at the bottom of the slide plate 43, and the slide plate 43 is slidably matched with the slider 42 through the through hole 432; the outer side of the slide plate 43 is rotatably connected to a rocker rod 44.

[0054] The above-mentioned slide plate 43 follows the sliding of the slider 42 and gradually approaches the outer slide rail 41, or the two slide plates 43 slide toward each other and gradually approach each other as the slider 42 slides, thereby adapting to peeled veneers of multiple widths, thereby correcting the peeled veneers in the horizontal direction. However, the peeled veneers still have a longitudinal offset. Therefore, in one embodiment of the present invention, when the two slide plates 43 slide toward each other and gradually approach each other, the rocker rod 44 connected by the outer rotation can also drive the rocker rod 44 to gradually approach the peeled veneer and correct the peeled veneer in the longitudinal direction, thereby realizing the horizontal and vertical two-way correction of the peeled veneer, so that the center of the peeled veneer is aligned with the center of the support plate 21.

[0055] like Figures 1 to 7 As shown, one end of the rocker arm 44 passes through the slide plate 43, and one end of the rocker arm 44 is fixedly connected to a first gear 441, and the first gear 441 is set in the through hole 432; the other end of the rocker arm 44 rotates around the axis with the first gear 441; a clearance groove 421 is opened inside the slider 42, and a first rack 422 is fixed to the bottom surface of the clearance groove 421, and the first gear 441 is meshed with the first rack 422.

[0056] As mentioned above, the rocker arm 44 can correct the longitudinal deviation of the peeled veneer, but if the rocker arm 44 is set vertically in the initial stage, the feeding direction of the peeled veneer may be blocked, resulting in the peeled veneer being blocked when it freely falls from the conveyor belt to the support plate 21, and thus cannot fall onto the support plate 21. On this basis, in one embodiment of the present invention, all rocker arms 44 are in a horizontal state in the initial stage, which does not affect the peeled veneer from the conveyor belt to the support plate 21. Subsequently, in the process of the rope 46 pulling the slider 42 to move, the slider 43 will slide synchronously on the slider 42, and then the first gear 441 set at one end of the rocker arm 44 is engaged with the first rack 422 on the inner side of the slider 42, thereby driving the rocker arm 44 to rotate toward the support plate 21. During the rotation of the rocker arm 44, the peeled veneer can be corrected in the longitudinal direction.

[0057] like Figures 1 to 7 As shown, a slide groove 411 is provided on the outer slide rail 41, and the top of the slider 42 is slidably connected in the slide groove 411. A spring 49 is also provided inside the outer slide rail 41, and the two ends of the spring 49 are respectively fixed between the slider 42 and the side wall of the outer slide rail 41.

[0058] After the electromagnet is powered off and retracted, the support plate 21 is pulling the rope 46, and when the rope 46 is used to pull the slide bar 48, it can no longer pull the slider 42, and the slider 42 can be reset to its initial state under the action of the spring 49. That is to say, after the slider 42 and the slide plate 43 cooperate with the rocker arm 44 to complete the horizontal and vertical correction of the peeled veneer, it is no longer necessary to continue the correction. At this time, the electromagnet is powered off and retracted, and the rocker arm 482 and the support arm 483 are used to make the slide bar 48 and the slider 42 only retain a sliding cooperation relationship. When the rope 46 pulls the slide bar 48 again, the slide bar 48 and the slider 42 slide relative to each other. At this time, the spring Under the action of 49, the slider 42 can be driven to reset, and the slider 42 is reset, so that the second gear 45 engages with the teeth in the opposite direction, and the second rack 47 is displaced in the opposite direction, driving the slider 43 to reset to the initial state. In addition, the reset of the slider 43 will drive the rocker bar 44 to reset to the initial state. That is to say, when the spring 49 drives the slider 42 to reset, the slider 43 and the rocker bar 44 will both reset. In addition, since there is a sliding fit relationship between the slide bar 48 and the slider 42 at this time, and relative sliding occurs, therefore, before the next work, it is necessary to use the electromagnet to energize the output to re-establish the snap-fit relationship between the slide bar 48 and the slider 42.

[0059] Working principle: By utilizing the acceleration of the conveyor belt combined with the gravity of the peeled veneer itself, when the peeled veneer is separated from the conveyor belt, it can freely fall to the surface of the support plate 21. There may be a tilt problem. At this time, the support plate 21 moves up, and the rope 46 is used to tighten the slider 42, so that the slider 42 slides in the outer slide rail 41. When the slider 42 slides from the side plate 30 toward the support plate 21, the symmetrically arranged deviation correction unit can use the rope 46 of equal length to pull the two sliders 42, so that the two sliders 42 move synchronously with the same displacement. The veneer is then adjusted to the desired distance, and the offset veneer is corrected so that the center line of the veneer is aligned with the center line of the support plate 21. As the support plate 21 further drives the veneer to move up and contact the bottom support plate 33, the positions of the two ends of the veneer in contact with the two bottom support plates 33 are as symmetrical as possible, and the veneer is kept horizontal when sliding with the bottom support plate 33 until the veneer squeezes the bottom support plate 33 and deflects at a larger angle. At this time, the side edge of the veneer is almost perpendicular to the bottom surface of the bottom support plate 33, and the support plate 21 continues to The peeled veneer is continuously squeezed upward, and the peeled veneer breaks through the bottom support plate 33. Then the support plate 21 contracts downward, and the peeled veneer falls on the surface of the reset bottom support plate 33 under the action of gravity and is received by the bottom support plate 33. In the above process, the peeled veneer is first received by the support plate 21, and moves upward with the support plate 21 until it contacts the bottom support plate 33, and then slides with the bottom support plate 33 and is received by the bottom support plate 33, corresponding to the feeding and temporary storage action of the peeled veneer. Among them, it is worth noting that the bottom support plate 33 The bottom support plate 33 is fixedly connected to the rotating shaft 31 by a spline, and a torsion spring is provided between the end of the rotating shaft 31 and the side plate 30. After the bottom support plate 33 is passively deflected by a large angle, the bottom support plate 33 is driven to return to its original position. In conjunction with the support rod 32, the bottom support plate 33 can be kept in a horizontal state after being reset, thereby realizing the temporary storage function of the peeled veneers. After a certain number of peeled veneers are stored on the bottom support plate 33, a forklift can be used to transfer the batch of peeled veneers to another location, such as to a pallet, and then the pallet is lifted by the forklift to the storage area for long-term storage.

[0060] When the support plate 21 moves up, the rope 46 can be used to drive the slider 42 to slide inside the outer slide rail 41, so that the symmetrical and synchronous slider 42 can be used to correct the deviation of the peeled veneer. However, if the support plate 21 continues to move up, it may cause the slider 42 to move excessively, thereby causing squeezing or even deformation of the two ends of the peeled veneer. Therefore, the maximum displacement distance of the slider 42 should be limited. In one embodiment of the present invention, in the initial state, the electromagnet is energized and output, which can make the support arm 483 and the swing arm 482 rise synchronously, thereby making the other end of the slide rod 48 engage with the slider 42. When the rope 46 is pulled by the support plate 21, the slide rod 48 and the slider 42 are locked. The snap-fitting can drive the slider 42 to slide in the outer slide rail 41. During the sliding process, the slider 42 contacts the offset peeled veneer, and under the action of the symmetrical and synchronous displacement of the slider 42, the peeled veneer is successfully corrected. Thereafter, if the support plate 21 continues to move upward, the slider 42 is pulled by the rope 46, which will cause the side wall of the peeled veneer to be squeezed. At this time, the electromagnet is de-energized and retracted, and the swing arm 482 and the support arm 483 are retracted in the movable groove 481. The rope 46 is pulled by the support plate 21, which will transfer force to the slide bar 48, causing relative sliding between the slide bar 48 and the slider 42, and will not drive the slider 42 to continue to move, thereby squeezing the peeled veneer that has been corrected.

[0061] Slide plates 43 are provided at both ends of the slider 42. When the slider 42 slides inside the outer slide rail 41 driven by the rope 46, the slide plates 43 can be used to contact and squeeze the peeled veneer, so that the peeled veneer is corrected. However, in this process, in order to prevent the slider 42 from being continuously displaced by the rope 46, it is necessary to use an electromagnet to control the movement of the swing arm 482 and the support arm 483. It can be understood that when the electromagnet is energized, the swing arm 482 and the support arm 483 are lifted, which can form a snap-fitting relationship between the slide bar 48 and the slider 42. At this time, when the rope 46 is pulled, the slide bar 48 drives the slider 42 to move. Conversely, when When the electromagnet is powered off and retracts, the swing arm 482 and the support arm 483 retract in the movable groove 481. At this time, the rope 46 is pulled, and the slide bar 48 will slide relative to the slider 42 and will not continue to drive the slider 42 to move. Based on the above, a movable plate 431 is set on the slide plate 43 at both ends of the slider 42. When the force on the movable plate 431 is analyzed, if the action force and the reaction force are equal, an electrical signal is generated, and the circuit of the electromagnet is automatically cut off through the electrical signal, so that the electromagnet is powered off and retracted. At this time, the support plate 21 pulls the rope 46 and cannot drive the slider 42 to continue to move, thereby avoiding squeezing the side wall of the rotary cut veneer.

[0062] Since the width of the peeled veneer is variable, the slide 43 in the fixed position may not be able to contact the peeled veneer during the sliding process of the slider 42, and thus cannot correct the peeled veneer. In one embodiment of the present invention, when the rope 46 pulls the slider 42 to slide in the outer slide rail 41, the second gear 45 on the slider 42 will mesh with the teeth on the outer side of the outer slide rail 41 and rotate under the meshing action. When the second gear 45 rotates, it can drive the second rack 47 meshed with it to slide. When the second rack 47 slides, it can drive the slide 43 to slide on the slider 42. Specifically, in the initial state, the slide 43 is located at the end position of the slider 42. In a correction unit, a slide 43 is provided at both ends of the slider 42, and a second rack 47 is fixed to the outer side wall of any slide 43. The two symmetrically arranged second gears 45 can mesh with the symmetrically arranged second rack 47, and at the same time drive the slide 43 to slide on the slider 42. It can be understood that Figure 3 For example, when the rope 46 pulls the slider 42 from its initial position to slide close to the support plate 21, the second gear 45 meshes with the teeth on the outer slide rail 41, causing the second gear 45 to rotate, thereby driving the two second racks 47 to move toward each other, thereby driving the two slides 43 to move toward each other. Therefore, in the process of the slider 42 being pulled by the rope 46 to slide, the two slides 43 slide from the ends of the slider 42 to the middle. At the same time, with the change in the position of the slider 42, the two slides 43 gradually approach the middle, thereby being able to adapt to peeled veneers of multiple widths and realize the correction of peeled veneers of multiple widths. It is worth noting that the two second racks 47 are staggered up and down, and correspondingly, the second gear 45 also has structural adaptive adjustment; the rocker arm 44 can perform longitudinal correction on the peeled veneer, but If the rocker arm 44 is set vertically in the initial stage, the feeding direction of the peeled veneer may be blocked, and the peeled veneer is blocked when it freely falls from the conveyor belt to the support plate 21, and thus cannot fall onto the support plate 21. On this basis, in one embodiment of the present invention, all the rocker arms 44 are in a horizontal state in the initial stage, which does not affect the peeled veneer from freely falling from the conveyor belt to the support plate 21. Subsequently, in the process of the rope 46 pulling the slider 42 to move, the slider 43 will slide synchronously on the slider 42, and then the first gear 441 set at one end of the rocker arm 44 is engaged with the first rack 422 on the inner side of the slider 42, thereby driving the rocker arm 44 to rotate toward the support plate 21. During the rotation of the rocker arm 44, the peeled veneer can be corrected in the longitudinal direction.
