Description

Technical Field

[0001] The present invention relates to the field of peeling devices, and particularly to a bark peeling machine. Background Art

[0002] A peeling machine generally refers to peeling the bark off a tree trunk.

[0003] In the prior art, for example, a peeling machine with Chinese Patent Application No. 201120355216.1 includes a roller with plate teeth supported by bearings. On both sides of the upper part of the roller, there are baffles, and the baffles are connected to roller plates extending upward. The roller is a series connection of two rollers, and the roller necks between the two rollers are connected by a coupling. The corresponding baffles and roller plates are also connected in series. This utility model connects two peeling machines together, with a coupling arranged in the middle, which does not damage the log and can well peel the bark of the log.

[0004] However, after actually peeling the bark of Phellodendron amurense, it is necessary to further separate the inner bark and the outer bark of the Phellodendron amurense bark to form materials of different qualities.

[0005] In view of the above problem of re-peeling the bark, we designed a bark peeling machine to divide the peeled bark into two pieces. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the defects existing in the prior art. The present invention provides a bark peeling machine that divides the peeled bark into two pieces.

[0007] To solve the above technical problem, the technical solution adopted by the present invention is: a bark peeling machine, including:

At the gap, a bark peeling knife mechanism is installed for peeling the bark conveyed by the first conveyor belt into two pieces. One piece of bark is conveyed out from the second conveyor belt, and the other piece of bark is removed from the gap;

[0009] A pressing mechanism is arranged on the U-shaped working plate, and the pressing mechanism enables the bark to be peeled and the finished bark to be stably conveyed.

[0010] Furthermore, the pressing mechanism includes two first mounting plates, which are respectively connected to the limiting sliding grooves formed on both sides of the U-shaped working plate in a limiting and sliding manner.

The guide pressing plate includes a first horizontal plate, an inclined plate, and a second horizontal plate connected in sequence. The first horizontal plate and the second horizontal plate are parallel, and the two inclined plates of the two guide pressing plates are in an inverted V shape. A second conveyor roller is rotatably connected between the two second horizontal plates. The second conveyor roller cooperates with the first conveyor belt to press and convey the middle part of the bark that has just entered the device. Then, the bark is gradually opened by the two inverted V-shaped guide pressing plates and made to be flat. A plurality of third rollers with gradually increasing widths are rotatably connected between the two guide pressing plates, and third rollers are also rotatably connected to the two first horizontal plates, so that the bark rolled up on both sides is smoothly conveyed under the cooperation of the second conveyor roller, the third rollers, and the first conveyor belt;

[0011] It also includes a plurality of first conveyor rollers rotatably connected between the two first mounting plates. A rotating mechanism for synchronously rotating the plurality of first conveyor rollers is provided on the first mounting plates. The horizontal height of the plurality of first conveyor rollers is higher than that of the third rollers and the second conveyor roller.

[0012] Furthermore, the minimum horizontal distance between the first conveyor roller closest to the third roller and the third roller is less than the minimum horizontal distance between the second conveyor belt and the third roller, so that the bark after peeling is power-guided by the first conveyor roller onto the top of the second conveyor belt and stably conveyed out.

[0013] Furthermore, the rotating mechanism includes a plurality of first rotating columns. One end of each of the plurality of first conveyor rollers is fixedly connected with a first rotating column. The plurality of first rotating columns are jointly sleeved with a toothed belt, so that when one of the first rotating columns rotates, each first rotating column rotates synchronously;

[0014] A first gear is fixedly connected to the outer wall of one of the first rotating columns. A second rotating column is rotatably connected to the first mounting plate. A second gear meshing with the first gear is fixedly connected to the outer wall of the second rotating column. A motor mounting plate is fixedly installed on the first mounting plate. A first motor is installed on the top of the motor mounting plate. The first motor is connected to the second rotating column.

[0016] Further, upper and lower moving mechanisms are fixedly connected to both sides of the U-shaped working plate, the two upper and lower moving mechanisms are respectively connected to the two first mounting plates, the upper and lower moving mechanism includes a second mounting plate and a third mounting plate, the second mounting plate and the third mounting plate are both fixedly connected to the U-shaped working plate, a threaded rod is rotatably connected between the second mounting plate and the third mounting plate, a sliding plate is threadedly connected to the outer wall of the threaded rod, both sides of the top of the sliding plate are fixedly connected with connecting plates, the connecting plates are slidably connected in the limiting sliding holes on the third mounting plate in a limiting manner, and the top thereof is connected to the first mounting plate;

[0017] It further includes a second motor, the power output end of the second motor is connected to the threaded rod, and the sliding plate is slidably connected in the limiting sliding groove in a limiting manner.

[0018] Further, longitudinal teeth are arranged inside one of the first mounting plates, a first bearing seat is fixedly connected to the U-shaped working plate, a third rotating column is rotatably connected to the first bearing seat, a third gear meshing with the teeth is fixedly connected to one end of the third rotating column, a first bevel gear is fixedly connected to the other end of the third rotating column, and a second bevel gear meshing with the first bevel gear is fixedly connected to the top of the fourth rotating column. When the bark is thick, the pressing mechanism moves down less, the blade rotates less, and the blade has a large inclination angle, so that the time for completely cutting open the side of the bark during peeling is long, and thus the peeling is safer; similarly, when the bark is thin, the pressing mechanism moves down more, at this time the blade rotates more, and the blade has a small inclination angle, so that the time for completely cutting open the side of the bark during peeling is short, and thus the peeling is more efficient.

[0019] Further, a fourth roller is rotatably connected to the first cross plate of the guide pressing plate, and the fourth roller is close to the blade on the triangular guiding and peeling plate and is used to press the other corner of the bark being peeled at the corner.

[0020] Further, a collection box is arranged at the bottom of the gap between the first conveyor belt and the second conveyor belt.

[0021] Further, a top plate is fixedly connected to the tops of the two first mounting plates.

[0022] Compared with the prior art, the beneficial effects of the present invention include: the device can continue to peel the bark into two pieces and separate and transmit them respectively. For the bark of Phellodendron amurense, it can be divided into two materials of different qualities;

[0023] The pressing distance can be adjusted according to the thickness of the bark, so that the bark can be stably and safely transmitted and cut;

[0024] The bark that is rolled up on both sides can be flattened, cut and transmitted;

[0025] The blade inclination angle can be automatically adjusted according to the bark of different thicknesses, so that the bark can be better peeled;

[0026] When the device needs to be maintained, the cutting tool is automatically stored at the edge of the first mounting plate, so that personnel can perform maintenance operations more safely. And when the device gets stuck, the storage of the blade basically does not affect the bark, so that the device can have a better service life during operation;

[0027] The device has integrated, efficient and automatic peeling, and comprehensively considers safety, cutting of different thickness barks, and subsequent maintenance safety, with significant progress. BRIEF DESCRIPTION OF THE DRAWINGS

And the distance between the first conveyor belt 4 and the second conveyor belt 15 is 10 cm of the limit chute. The first conveyor belt 4 is the initial placement area, and the second conveyor belt 15 is the area for discharging the inner pulp of the bark.

[0045] Third mounting plates 14 and second mounting plates 9 are fixedly connected to both sides of the U-shaped working plate 1. A threaded rod 13 is rotatably connected between the third mounting plate 14 and the second mounting plate 9. A second motor 8 is installed at the bottom of the second mounting plate 9, and the power output end of the second motor 8 is connected to the threaded rod 13. A sliding plate 11 is threadedly connected to the outer wall of the threaded rod 13, and the sliding plate 11 is limited and slidably connected in the limit chute 10 on the U-shaped working plate 1. And both sides of the top of the sliding plate 11 are fixedly connected with connecting plates 12, and the connecting plates 12 are limited and slidably connected in the limit sliding holes on the third mounting plate 14. The top of the connecting plate 12 is fixedly connected with a first mounting plate 2, and the first mounting plate 2 is also limited and slidably connected to the limit chute 10 on the U-shaped working plate 1.

The distance between the two first horizontal plates is greater than the distance between the two second horizontal plates. The two inclined plates are in an inverted V shape. The two second horizontal plates are close to the initial end of the first conveyor belt 4. A second conveyor roller 17 is rotatably connected between the two second horizontal plates, and the second conveyor roller 17 is used to press the middle part of the bark to be peeled. The inclined plate is used to gradually open the bark pressed in the middle. And a plurality of third rollers 19 with gradually increasing lengths are rotatably connected between the two guide pressing plates 18, which are used to press and flatten the gradually unfolded bark. A plurality of third rollers 19 are rotatably connected between the two first horizontal plates of the two guide pressing plates 18, which are used to continue to press and flatten the bark to be peeled and convey it.

The horizontal height of the first conveyor rollers 3 is higher than that of the second conveyor roller 17, the third roller 19, and the fourth roller 20. And the plurality of first conveyor rollers 3 are closer to the third roller 19 relative to the second conveyor belt 15, that is, the nearest first conveyor roller 3 is placed directly above the third roller 19, so that the bark exported from the triangular guide and peeling plate 35 is guided and transmitted by the first conveyor roller 3 and transmitted to the top of the second conveyor belt 15.

A collection box 16 is arranged at the bottom of the gap between the first conveyor belt 4 and the second conveyor belt 15 for collecting the bark peeled off at the bottom.

[0049] Embodiment 2: On the basis of Embodiment 1, better technical means for peeling bark are added.

[0050] Key reference Figure 9 and 11 , longitudinal teeth 27 are arranged on the inner wall of one of the first mounting plates 2. A first bearing block 30 is fixedly connected to the U-shaped working plate 1. A third rotating column 29 is rotatably connected to the first bearing block 30. One end of the third rotating column 29 is fixedly connected with a third gear 28 meshing with the teeth 27. A first bevel gear 31 is fixedly connected to the other end of the third rotating column 29. The first bevel gear 31 meshes with a second bevel gear 32 at the top of the fourth rotating column 34. The positions of all power components are set in the directions required for the effect.

[0051] The triangular guide and peeling plate 35 of this device should be actually installed according to the initial predicted slice thickness.

[0052] The other structures of this embodiment are the same as those of the first embodiment.

[0053] In a specific implementation, to determine the thickness of the bark of this batch, the controller simultaneously starts two second motors 8. The second motors 8 cause the threaded rods 13 to rotate, and with the cooperation of the limit and the threads, the two first mounting plates 2 are simultaneously lowered to a preset position. At this time, the second conveyor roller 17, the third roller 19, the fourth roller 20, and the first conveyor roller 3 all move accordingly.

[0054] The controller starts the control motor power supplies of the first conveyor belt 4 and the second conveyor belt 15, so that the first conveyor belt 4 and the second conveyor belt 15 also rotate at the same speed. At this time, the middle part of the Phellodendron amurense bark to be peeled is stuffed into the bottom of the second conveyor roller 17. With the cooperation of the first conveyor belt 4 and the second conveyor roller 17, the Phellodendron amurense bark rolled up on both sides gradually goes deeper into the second conveyor roller 17. At this time, with the cooperation of the inclined plate of the guide pressing plate 18, the bark rolled up on both sides is gradually flattened to the bottom of the guide pressing plate 18. Then the bark is gradually flattened by a plurality of third rollers 19. At this time, the triangular guide and peeling plate 35 is triangular, and one corner of the horizontally conveyed bark first contacts the triangular guide and peeling plate 35. When the bark whose one corner first contacts the triangular guide and peeling plate 35 is cut, the other corner on the same side is pressed by the fourth roller 20. So that the bark is well cut and peeled. Then the upper layer of the peeled bark is conveyed out from the upper part of the triangular guide and peeling plate 35, and moves to the bottom of the first conveyor roller 3, and is conveyed to the top of the second conveyor belt 15 through the conveyance of the first conveyor roller 3, and the upper layer of the bark is conveyed out through the cooperation of the second conveyor belt 15 and the first conveyor roller 3, while the lower layer of the bark moves downward under the blockage of the bottom of the triangular guide and peeling plate 35 and moves into the collection box 16.

[0055] In the initial state of the device, the first mounting plate 2 is at a high position, and the side edges of the triangular guide and peeling plate 35 and the U-shaped working plate 1 are kept horizontal, that is, there is a completely empty state between the first conveyor roller 3 and the second conveyor belt 15, and between the third roller 19 and the first conveyor belt 4.

[0056] When the bark is thick, at this time the first mounting plate 2 moves downward a short distance, at this time the triangular guide and peeling plate 35 also rotates a small number of degrees, at this time the triangular guide and peeling plate 35 has a larger inclination angle, and in the same-speed state, the time to peel one side of the bark is longer. In this way, it is safer to peel the thicker bark.

[0057] When the bark is thin, at this time the first mounting plate 2 moves downward a long distance, at this time the triangular guide and peeling plate 35 also rotates a large number of degrees, at this time the triangular guide and peeling plate 35 has a larger inclination angle, and in the same-speed state, the time to peel one side of the bark is shorter. On the premise of ensuring the safety of peeling, it peels faster, and such efficiency is relatively better.

[0058] And when it is necessary to check the internal condition of the machine or perform maintenance, the first mounting plate 2 is directly moved to the high position. At this time, the triangular guide and peeling plate 35 directly returns to the side of the U-shaped working plate 1 and is parallel to the side of the U-shaped working plate 1. At this time, the triangular guide and peeling plate 35 will not easily damage the maintenance personnel, greatly improving the safety of the personnel.

[0059] The technical scope of the present invention is not limited to the content described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
