[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] (1) The present invention is provided with a rotating ring, a connecting rod, an inner gear ring, a second gear, a rotating drum, a push rod and a moving ring. When the position of the stripping knife blade needs to be adjusted in a rotating state to strip wood with different diameters, the rotating frame drives multiple stripping knives to rotate, and at the same time, multiple rotating drums and multiple push rods are used to make the moving ring and the rotating frame rotate synchronously. The moving ring in the rotating state is pushed on one side of the rotating frame to gradually extend the push rod into the rotating drum. The protrusion on the push rod makes the rotating drum rotate on the outside of the push rod through the spiral guide groove in the rotating drum, thereby driving the second gear to rotate around the axis of the rotating drum, that is, realizing the self-rotation of the second gear. The inner gear ring is rotated relative to the rotating frame through the meshing transmission between the second gear and the inner gear ring, and then the rotating ring is rotated relative to the rotating frame, so that the connecting rod pulls the end of the stripping knife to make the stripping knife rotate relative to the rotating frame in the rotating frame, thereby adjusting the position of the stripping knife blade in the rotating state, which is used for stripping wood with different diameters. No shutdown operation is required, and the processing efficiency is high.

[0019] (2) The present invention is provided with a push frame and a trapezoidal block. When the upper pressure roller and the lower pressure roller clamp the wood, the double-headed screw is rotated so that the sliders screwed together at both ends move toward the middle, thereby causing the trapezoidal block fixedly connected to the slide frame to also move toward the middle. The inclined surface of the trapezoidal block slides against the guide inclined surface on the push frame, so that the trapezoidal block pushes the end of the push frame to extend into the fixed frame, thereby pushing the moving ring to move relative to the rotating frame, thereby realizing the adjustment of the position of the stripping knife blade. The push frame and the moving ring are in conflict with each other, and the push frame will not hinder the rotation of the moving ring and the rotating frame. In this way, the position of the stripping knife blade can be adjusted while clamping the wood, thereby improving efficiency.

[0020] (3) The present invention is provided with a V-shaped frame. When the two slides located at the bottom drive the lower pressure roller to move, the V-shaped frame is driven to rise and fall through the lifting rod, so that the top of the V-shaped frame is always flush with the top of the adjacent lower pressure roller, so that the wood can enter horizontally between the multiple peeling knives, avoiding the end of the wood from tilting and hitting the blade of the peeling knife when the lower pressure roller conveys the wood, thereby improving the service life of the equipment.

[0021] (4) The present invention is provided with a moving frame and a lifting frame. When the wood falls onto the V-shaped frame during loading, the double-headed screw is rotated to make the slide drive the V-shaped frame downward through the lifting rod. When the top of the lifting frame is higher than the top of the V-shaped frame, a plurality of lifting frames support the wood. Then, the moving frame is moved on the frame so that the lifting frame drives the end of the wood to move between the upper pressure roller and the lower pressure roller. Then, the double-headed screw is rotated in the opposite direction so that the slide drives the upper pressure roller and the lower pressure roller to clamp the end of the wood. In this way, automatic feeding is realized, the labor intensity of workers is reduced, and efficiency is improved.

[0022] (5) The present invention is provided with a pressing frame and a limit assembly, and the slide frame drives the V-shaped frame to move downward through the lifting rod. Before the bottom of the V-shaped frame collides with the top of the pressing frame, the lifting rod pushes the first clamping block to compress the third spring. At this time, the end of the second clamping block collides with the side of the pressing frame, so that the slide bar compresses the fourth spring, and then the V-shaped frame continues to move downward. When the bottom of the V-shaped frame collides with the top of the pressing frame, the wood is supported on multiple lifting frames at this time, and then the V-shaped frame pushes the pressing frame to move downward to compress the first spring, and at the same time, the slide column moves downward. Through the cooperation of the slide column and the inclined groove, the movable frame drives the wood to move between the upper pressing roller and the lower pressing roller through the multiple lifting frames, until the pressing frame moves downward to make the clamping groove move to one side of the second clamping block, and the elastic force of the fourth spring causes the slide bar to push the second clamping block The lifting frame is moved upward by the lifting rod and the second lifting frame is moved downward by the lifting rod, and the pressing frame is prevented from rising and moving upward by the lifting rod.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] See also Figure 1-Figure 12 As shown, the present invention provides the following technical solutions:

[0038] A debarking machine for wood processing, comprising a frame 1 and a fixed frame 7 fixed on the frame 1, a rotating frame 17 is rotatably connected inside the fixed frame 7, a plurality of debarking knives 20 are rotatably connected to the inner side of the rotating frame 17 in a circumferential array, a rotating ring 21 is rotatably connected to one side of the rotating frame 17, and a connecting rod 22 is rotatably connected between the end of each debarking knives 20 and the inner side of the rotating ring 21;

[0039] A plurality of rotating drums 31 are rotatably connected to one side of the rotating frame 17, and a second gear 30 is coaxially fixed to the outer side of each rotating drum 31. An inner gear ring 23 is coaxially fixed to one side of the rotating ring 21, and the plurality of second gears 30 are meshed with the inner gear ring 23.

[0040] A moving ring 18 is slidably connected to one side of the rotating frame 17, and a plurality of push rods 35 are fixedly installed on one side of the moving ring 18. The ends of each push rod 35 extend into the plurality of rotating cylinders 31 one by one, and a second spring 32 is provided between the end of each push rod 35 and the inside of the corresponding rotating cylinder 31. A protrusion 36 is fixed to the outside of each push rod 35, and a spiral guide groove slidably matched with the protrusion 36 is provided in each rotating cylinder 31.

[0041] A first gear 6 is rotatably provided on the fixed frame 7 , an outer gear ring 19 is coaxially fixed to the outer side of the rotating frame 17 , and the first gear 6 and the outer gear ring 19 are meshed and connected.

[0042] Based on the above disclosed structure, when performing the wood peeling operation:

[0043] First, the first gear 6 is driven to rotate by the motor, and the outer gear ring 19 is driven by the meshing transmission of the first gear 6 and the outer gear ring 19, so that the outer gear ring 19 drives the rotating frame 17 to rotate, and the rotating frame 17 drives the multiple stripping knives 20 to rotate around the axis of the rotating frame 17, and the rotating frame 17 drives the multiple rotating drums 31 to rotate around the axis of the rotating frame 17, so that the multiple second gears 30 and the push rods 35 in the rotating drums 31 rotate around the axis of the rotating frame 17, and then the moving ring 18 and the rotating frame 17 rotate synchronously;

[0044] During the peeling operation, the moving ring 18 and the rotating frame 17 are relatively fixed in the horizontal direction, so that the multiple push rods 35 are relatively fixed to the rotating frame 17, and the multiple rotating drums 31 and the multiple second gears 30 are also relatively fixed to the rotating frame 17 through the cooperation of the protrusion 36 on the push rod 35 and the spiral guide groove in the rotating drum 31, so that the internal gear ring 23 meshing and connected to the outer side of the multiple second gears 30 rotates synchronously with the rotating frame 17, and then the rotating ring 21 and the rotating frame 17 rotate synchronously, and the end of the stripping knife 20 is connected to the rotating ring 21 through the connecting rod 22, and the stripping knife 20 is rotatably connected to the rotating frame 17, so that the stripping knife 20 and the rotating frame 17 are relatively fixed when the rotating frame 17 drives the stripping knife 20 to rotate, so as to avoid the blade of the stripping knife 20 from separating from the wood surface during the peeling process;

[0045] The wood is then moved along the axis of the rotating frame 17. When the wood passes between the plurality of peeling knives 20, the blades of the rotating peeling knives 20 scrape the surface of the wood, thereby performing a peeling operation on the wood.

[0046] As mentioned above, regarding the movement of wood, it is preferred to have the following structure:

[0047] Both sides of the fixed frame 7 are rotatably connected with double-headed screws 14, and both ends of the two double-headed screws 14 are screwed and connected with slides 15. Two upper pressure rollers 8 are rotatably connected between the two upper slides 15, and two lower pressure rollers 9 are rotatably connected between the two lower slides 15. The two upper pressure rollers 8 and the two lower pressure rollers 9 are respectively located on both sides of the fixed frame 7;

[0048] A first pulley 10 is coaxially fixed to the ends of the two lower pressure rollers 9, and a first belt 11 is rotatably connected between the two first pulleys 10; a second pulley 12 is coaxially fixed to the ends of the two double-headed screws 14, and a second belt 13 is rotatably connected between the two second pulleys 12.

[0049] As can be seen from the above, the two sides of the fixed frame 7 are the feed side and the discharge side respectively, and the end of the wood is placed between the upper pressure roller 8 and the lower pressure roller 9 on the feed side, and one of the double-headed screws 14 is driven to rotate to drive the coaxially fixed second pulley 12 to rotate, and the other second pulley 12 drives the other double-headed screw 14 to rotate through the second belt 13, so that the two double-headed screws 14 rotate synchronously, so that the upper and lower sets of slides 15 connected by screwing drive the two upper pressure rollers 8 and the two lower pressure rollers 9 to move toward the middle until the upper pressure roller 8 and the lower pressure roller 9 on the feed side clamp the end of the wood;

[0050] Then drive one of the lower pressing rollers 9 to rotate and drive the coaxially fixed first pulley 10 to rotate, and through the first belt 11, the other first pulley 10 drives the other lower pressing roller 9 to rotate, so that the two lower pressing rollers 9 rotate synchronously, and through the friction between the lower pressing roller 9 and the wood, the upper pressing roller 8 and the lower pressing roller 9 convey the clamped wood along the axis of the rotating frame 17, and the upper pressing roller 8 and the lower pressing roller 9 on the feed side gradually extend the wood between the multiple peeling knives 20, so that the peeling knives 20 peel the wood, and the peeled end of the wood is output from the other end of the rotating frame 17 and moves between the upper pressing roller 8 and the lower pressing roller 9 on the discharge side, so that after the end of the wood is separated from the upper pressing roller 8 and the lower pressing roller 9 on the feed side, the upper pressing roller 8 and the lower pressing roller 9 on the discharge side can still be used to continue conveying, so as to achieve a complete peeling operation.

[0051] In addition, in order to peel wood of different diameters, two push racks 34 are slidably connected to one side of the fixed frame 7, and the ends of the two push racks 34 slide into the fixed frame 7 and abut against one side of the movable ring 18. Two guide inclined surfaces are symmetrically provided on one side of the two push racks 34, and trapezoidal blocks 33 are fixed on multiple slides 15. The inclined surfaces of the multiple trapezoidal blocks 33 slide against the multiple guide inclined surfaces respectively. Based on this, when the upper and lower groups of slides 15 move toward the middle, they respectively drive the multiple trapezoidal blocks 33 to move toward the middle, so that the multiple trapezoidal blocks 33 push the push frame 34 to move toward the fixed frame 7 through the guide inclined surface on the push frame 34, so that the push frame 34 pushes the movable ring 18 to make the push rod 35 extend into the rotating drum 31, and the protrusion 36 on the push rod 35 makes the rotating drum 31 rotate on the rotating frame 17 through the spiral guide groove in the rotating drum 31, thereby driving the second gear 30 to rotate relative to the rotating frame 17, so that the meshing connected internal gear ring 23 drives the rotating ring 21 to rotate relative to the rotating frame 17, and then the connecting rod 22 pulls the stripping knife 20 to rotate relative to the rotating frame 17, so as to adjust the distance between the blade of the stripping knife 20 and the axis of the rotating frame 17, which is used for stripping wood of different diameters, and the blade position of the stripping knife 20 can be adjusted while clamping the wood, which is more efficient.

[0052] In addition, the end of the push frame 34 is in contact with one side of the movable ring 18. When the rotating frame 17 is in a rotating state, the push frame 34 can still be used to push the movable ring 18 to move, so as to adjust the position of the stripping knife blade in the rotating state without stopping for adjustment, and the processing efficiency is high.

[0053] It is worth noting that when the rotating frame 17 drives the stripping knife to perform the peeling operation, the second spring 32 in the rotating drum 31 pushes the push rod 35, and the movable ring 18 always pushes the frame 34 to resist, and the rotating frame 17 in the rotating state will not apply horizontal force to the movable ring 18, thereby ensuring that the movable ring 18 and the rotating frame 17 are relatively fixed in the horizontal direction during the peeling operation, ensuring the smooth progress of the peeling operation.

[0054] In addition, two fixed plates 2 are fixedly installed on both sides of the fixed frame 7 on the frame 1, and lifting rods 3 are slidably connected to the outer sides of the four fixed plates 2. A V-shaped frame 4 is vertically slidably connected between the two fixed plates 13 on the same side, and the tops of the two V-shaped frames 4 are flush with the tops of the two lower pressure rollers 9 respectively. Both sides of the two V-shaped frames 4 pass through the fixed plates 2 and are fixedly connected to the lifting rods 3. The four lifting rods 3 are fixedly connected to the two ends of the two slides 15 located below. Based on this, when the two slides 15 located below drive the lower pressure roller 9 to move up and down, they drive the lifting rods 3 to move up and down on both sides of the fixed plate 2, so that the V-shaped frame 4 and the lower pressure roller 9 are synchronously lifted and lowered, so that the top of the V-shaped frame 4 is always flush with the top of the adjacent lower pressure roller 9, and when the wood moves along the axis of the rotating frame 17 and extends into the plurality of stripping knives 20, it can horizontally enter between the plurality of stripping knives 20, so as to prevent the end of the wood from tilting and hitting the blade of the stripping knives 20, thereby improving the service life.

[0055] In addition, after the wood rolls from the fixed plate 2 and the V-shaped frame 4 to the V-shaped frame 4, it is necessary to push the wood so that its end extends between the upper pressing roller 8 and the lower pressing roller 9 on the feeding side, preferably with the following structure:

[0056] A mobile frame 29 is horizontally slidably connected to the frame 1, a plurality of lifting frames 5 are fixedly mounted on the top of the mobile frame 29, and a plurality of through slots for the lifting frames 5 to pass through are provided on the V-shaped frame 4;

[0057] Two pressing frames 25 are vertically slidably connected to the frame 1 below one of the V-shaped frames 4. The two pressing frames 25 are provided with a card slot 26. A first spring 24 is fixedly installed between the two pressing frames 25 and the top of the frame 1. A sliding column 27 is fixedly connected between the bottoms of the two pressing frames 25. An inclined groove 28 is provided at the bottom of the mobile frame 29. The sliding column 27 is slidably matched in the inclined groove 28. The two fixed plates 2 are provided with a limit assembly that is slidably matched with the card slot 26.

[0058] The limiting assembly includes a slide cylinder 39 slidably connected to the fixed plate 2 and a slide rod 40 with one end slidingly extending into the slide cylinder 39, a fourth spring 38 is fixedly installed between the end of the slide rod 40 extending into the slide cylinder 39 and the interior of the slide cylinder 39, a second clamping block 41 slidably engaged with the clamping groove 26 is fixedly installed on the other end of the slide rod 40, a first clamping block 16 is fixedly installed at one end of the slide cylinder 39, a third spring 37 is fixedly connected between the first clamping block 16 and the fixed plate 2, the first clamping block 16 is a trapezoidal structure, and the hypotenuse of the first clamping block 16 is slidably engaged with the bottom of the lifting rod 3.

[0059] As can be seen from the above, after the wood rolls down from one side to the V-shaped frame 4 on the feeding side, the two double-headed screws 14 rotate to make the upper and lower groups of slides 15 move to the upper and lower sides respectively, and the two slides 15 located at the bottom drive the V-shaped frame 4 to move downward through the lifting rod 3. Before the bottom of the V-shaped frame 4 contacts the top of the pressing frame 25, the bottom edge of the lifting rod 3 pushes the first clamping block 16 to move toward the fixed plate 2 through the oblique edge of the first clamping block 16, so that the first clamping block 16 compresses the third spring 37. At this time, since the end of the second clamping block 41 contacts one side of the pressing frame 25, the second clamping block 41 and the slide rod 40 cannot move, so that the slide rod 40 and the slide cylinder 39 compress the fourth spring 38.

[0060] Then the slide 15 drives the lifting rod 3 and the V-shaped frame 4 to continue to move downward. When the bottom of the V-shaped frame 4 contacts the top of the two pressing frames 25, the wood is supported on the multiple lifting frames 5. Then the V-shaped frame 4 continues to move downward to push the two pressing frames 25 to move downward. The pressing frames 25 compress the first spring 24. At the same time, the two pressing frames 25 drive the sliding column 27 between the bottoms to move downward. The sliding column 27 pushes the inclined groove 28 on the moving frame 29, so that the moving frame 29 drives the multiple lifting frames 5 and the wood on the multiple lifting frames 5. Move toward the direction of the lower pressing roller 9, during which the ends of the first clamping block 16 and the second clamping block 41 respectively contact the side of the lifting rod 3 and the side of the pressing frame 25, and then the V-shaped frame 4 continues to push the pressing frame 25 downward until the clamping groove 26 on the pressing frame 25 moves to the side of the second clamping block 41, and the elastic force of the fourth spring 38 causes the sliding rod 40 to push the second clamping block 41 into the clamping groove 26, and at this time, the moving frame 29 and the plurality of lifting frames 5 have moved the end of the wood to between the upper pressing roller 8 and the lower pressing roller 9;

[0061] Then, the two double-headed screws 14 are rotated in the opposite direction to rotate the upper and lower sets of slides 15 toward the middle, and the two slides 15 at the bottom drive the V-shaped frame 4 to move upward through the lifting rod 3. Since the second clamping block 41 extends into the clamping groove 26, the elastic force of the first spring 24 cannot move the pressing frame 25 upward, so the moving frame 29 and the multiple lifting frames 5 cannot move either, until the lower pressing roller 9 and the V-shaped frame 4 on the feeding side lift the wood upward to separate the wood from the multiple lifting frames 5, and then the slide 15 at the bottom continues to drive the lifting rod 3 and the V-shaped frame 4 to move upward, and the bottom edge of the lifting rod 3 is gradually separated from the oblique edge of the first clamping block 16, and under the elastic force of the third spring 37, the first clamping block 16 is The first clamping block 16 gradually extends into the fixed plate 2, so that the first clamping block 16 pulls the sliding rod 40 and the second clamping block 41 to move through the sliding cylinder 39 and the fourth spring 38, so that the second clamping block 41 gradually slides out of the slot 26. When the end of the second clamping block 41 moves to one side of the pressing frame 25, the elastic force of the first spring 24 causes the pressing frame 25 to move upward, and the pressing frame 25 drives the sliding column 27 to move upward and pushes the moving frame 29 through the inclined groove 28 to drive the multiple lifting frames 5 to move in the direction away from the lower pressing roller 9, so that the pressing frame 25, the moving frame 29 and the multiple lifting frames 5 are reset, so as to facilitate continuous wood feeding operation, improve processing efficiency, and do not need to set up a separate driving device, thereby reducing manufacturing costs.

[0062] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
