Description

Technical Field

[0001] The invention belongs to the technical field of bamboo processing equipment, and in particular relates to a bamboo chip conveying device with a turning function. Background Art

[0002] The general processing steps of bamboo include slicing, removing bamboo partitions, and subsequent cutting, grinding, flattening, burning, etc. Therefore, at the front end of the entire processing step, the bamboo partitions need to be removed first. This is also the only way for the bamboo material to be made into bamboo mats, bamboo floors, bamboo baskets and other products.

[0003] In addition, the bamboo strips have two sides, the green side originally on the outside, and the yellow side originally on the inside. The bamboo partitions grow on the yellow side. For the bamboo partition cutting equipment that processes from top to bottom, the yellow side must face up, so there is a special equipment for flipping it up and down.

[0004] For example, a Chinese utility model patent with patent publication number CN211806672U and publication date 2020.10.30 discloses a wooden floor turning device, wherein: a cylindrical turning table is provided above the base, and a cylindrical support with a horizontal axis is connected to the top of the turning table. A cross bar passes through the support, and the cross bar and the support are coaxially arranged. The cross bar can rotate relative to the support. One end of the cross bar is coaxially fixed with the output shaft of the flipping motor, and the other end of the cross bar is fixed with a horizontally arranged two-way telescopic cylinder. The piston rod ends of the two-way telescopic cylinder are fixed with clamping rods vertical to the piston rods, and the two clamping rods are symmetrically arranged. The two clamping rods are fixed with long V-shaped claws on the opposite sides.

[0005] However, the turning device in this utility model patent has at least the following inconveniences during use.

[0006] First, the flipping action requires a 180° rotation, which is relatively large, so it is relatively more time-consuming and power-consuming.

[0007] Second, the V-shaped claws on both sides are used to clamp and flip, so the output feeding function is missing in the clamping direction.

[0008] Therefore, in summary, in view of the characteristics of bamboo strips themselves, a turning-over and conveying integrated equipment is needed that can turn over more quickly and efficiently and has the function of conveying and discharging in the length direction. Summary of the Invention

[0009] The present invention provides a bamboo chip conveying device with a turning function, which can achieve the purpose of turning over the bamboo chips on the supporting platform as needed and lifting each chip for conveying by arranging a servo motor, a telescopic cylinder and a turning frame unit on the mounting plate.

[0010] The technical solution adopted by the present invention to solve the above-mentioned problem is: a bamboo chip conveying device with a flipping function, including a mounting plate and a supporting platform, and also including a servo motor arranged on the mounting plate, a telescopic cylinder arranged on the servo motor, and a flipping frame unit arranged on the telescopic cylinder and capable of outputting bamboo chips with the green side facing upward in a manner such that the yellow side faces upward, and the rotation angle of the flipping frame unit when flipping the bamboo chips is an obtuse angle or an acute angle.

[0011] A further preferred technical solution is that the flip frame unit includes an end plate arranged on the cylinder shaft of the telescopic cylinder, and two side plates respectively arranged on both sides of the end plate and used for clamping the rear end in the conveying direction of the bamboo strips.

[0012] A further preferred technical solution is that the angle between the two side panels for clamping the bamboo strips is an acute angle.

[0013] A further preferred technical solution is that the flip frame unit further includes a lower bottom plate arranged between the two side plates and used for receiving bamboo chips loaded in a falling manner.

[0014] A further preferred technical solution is that after the bamboo pieces with the green surface facing upward are flipped from the lower bottom plate to one of the side plates, the telescopic cylinder can be used to carry out the conveying and discharging operation.

[0015] A further preferred technical solution is that the flip frame unit further includes an upper connecting plate arranged between the two side plates.

[0016] A further preferred technical solution is that the protruding length of the lower base plate on the end plate is greater than that of the upper connecting plate.

[0017] A further preferred technical solution is that a discharging drive wheel is provided at a position on the side of the support platform which is different from the position where the mounting plate is provided.

[0018] A further preferred technical solution is that the support platform is a lifting ring for inserting and placing bamboo chips, or a conveyor belt for supporting the falling bamboo chips.

[0019] A further preferred technical solution is that a sliding base for arranging the mounting plate is provided on the conveying device frame.

[0020] The present invention has the following advantages.

[0021] First, the conveying device is equipped with an existing visual inspection camera, so that the bamboo pieces with the green side facing up can be turned over and conveyed, while the bamboo pieces with the yellow side facing up can only be conveyed, ensuring that the subsequent bamboo partition removal operation is stable and effective.

[0022] Second, the rotation angle of the clamping and flipping is an obtuse angle, relying on the weight of the bamboo piece to finally complete the 180° flipping effect, and the flipping speed is relatively fast.

[0023] Third, when the cross-section of the bamboo piece is arc-shaped and the green side is facing upwards, the bamboo piece can be rotated and tilted over to be turned over. The rotation angle is an acute angle, and the bamboo piece relies on its own weight to finally complete a 180° flipping effect, which is faster.

[0024] Fourth, for the bamboo pieces that are actively clamped by the flipping frame unit, the clamping and flipping operations can be performed; for the fallen bamboo pieces, the bamboo pieces can be rotated and then tilted over to perform the flipping operation, ensuring that the flipping method is flexible and efficient.

[0025] Fifth, the telescopic cylinder itself has the basic lifting and conveying effect in the length direction of the bamboo strips. When combined with the driving wheel for discharging, it ensures that the discharging operation is faster and more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In the accompanying drawings, the components represented by each reference numeral are as follows: bamboo piece a, mounting plate 11, support platform 12, servo motor 1, telescopic cylinder 2, flip frame unit 3, end plate 301, side plate 302, lower base plate 303, upper connecting plate 304, discharge drive wheel 13, conveyor frame 14, and sliding base 15. DETAILED DESCRIPTION

[0031] The following description is merely a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.

[0032] Example: As shown in the attached Figure 1-4As shown, a bamboo chip conveying device with a flipping function includes a mounting plate 11 and a supporting platform 12, a servo motor 1 arranged on the mounting plate 11, a telescopic cylinder 2 arranged on the servo motor 1, and a flipping frame unit 3 arranged on the telescopic cylinder 2 and capable of outputting bamboo chips with the green side facing upward in a manner such that the yellow side faces upward, wherein the rotation angle of the flipping frame unit 3 when flipping the bamboo chips is an acute angle.

[0033] In this embodiment, the servo motor 1, the telescopic cylinder 2, and the existing visual inspection camera are all connected to a common controller to ensure that when the bamboo pieces with the green side facing up are input, the servo motor 1 works. Conversely, when the bamboo pieces with the yellow side facing up are input, the servo motor 1 does not work, and only the telescopic cylinder 2 completes the lifting and conveying operation.

[0034] In addition, the supporting platform 12 has the following functions: first, to ensure that the bamboo pieces do not fall; second, to provide appropriate friction to the bamboo pieces to prevent the flip frame unit 3 from being unable to clamp the bamboo pieces.

[0035] Finally, there are two ways for the bamboo pieces to enter the flip frame unit 3. The first is that the flip frame unit 3 actively clamps the bamboo pieces, and the second is that the bamboo pieces fall onto the flip frame unit 3. The two loading methods correspond to two different flipping methods.

[0036] The turning frame unit 3 includes an end plate 301 arranged on the cylinder shaft of the telescopic cylinder 2, and two side plates 302 respectively arranged on both sides of the end plate 301 and used for clamping the rear end in the conveying direction of the bamboo strips.

[0037] In this embodiment, the rear end of the bamboo strips in the conveying direction is the flip frame unit 3, and the two side plates 302 respectively clamp the two side edges of the bamboo strips at the rear end to ensure that the bamboo strips can move along with the side plates 302 when they rotate.

[0038] Therefore, a rubber sheet may be provided on the inner side surface of the side plate 302 to increase friction.

[0039] The angle between the two side panels 302 for clamping the bamboo strips is an acute angle.

[0040] In this embodiment, the two side panels 302 form a "V-shape", which ensures that the rear end of the bamboo piece can be clamped more stably. In addition, the extension and clamping action of the telescopic cylinder 2 together with the flip frame unit 3 can also be appropriately faster, and the clamping strength can also be improved to prevent the bamboo piece from falling when it rotates with the side panels 302.

[0041] Finally, the side panel 302 rotates, for example, 130° and then quickly withdraws backward, and the bamboo piece falls on the supporting platform 12, which is a complete 180° flip effect. The last 50° angle is completed by its own rotation when it falls, so compared with the prior art method of having to rotate a full 180°, this embodiment has higher efficiency.

[0042] It should be noted that when the bamboo piece turns over together with the turning frame unit 3, it has a height lifting function in the early stage of the rotation action and finally falls, so the support platform 12 will not block the rotation and turning action of the bamboo piece, the same below.

[0043] The flip frame unit 3 further includes a lower bottom plate 303 disposed between the two side plates 302 and used for receiving bamboo chips loaded in a falling manner.

[0044] In this embodiment, the flipping action of the flip frame unit 3 is more efficient, as described below.

[0045] First, the bamboo piece falls on the lower base plate 303 and the support platform 12. At this time, if the green side of the bamboo is facing upward, the servo motor 1 is turned on and rotated, for example, 20 degrees, and the bamboo piece slides to the angle between the lower base plate 303 and the side plate 302.

[0046] Secondly, the servo motor 1 controls the flip frame unit 3 to rotate, for example, 40°. The bamboo piece rotates with the angle between the lower base plate 303 and the side plate 302 as the center of the circle. Since the center of gravity of the bamboo piece has passed this angle, the bamboo piece spontaneously rotates another 40°. At this time, the bamboo piece is leaning on the side plate 302.

[0047] Third, the telescopic cylinder 2 retracts, the bamboo pieces fall, and the final 80° self-rotation is completed, thus completing the entire 180° flipping effect. During this process, the servo motor 1 controls the flipping frame unit 3 to rotate only 60°, so the flipping operation is extremely fast.

[0048] Finally, there are several points that require special attention when performing the flipping operation of the self-tilting method.

[0049] First, the length of the lower base plate 303 needs to be relatively large, for example, accounting for 40% of the length of the bamboo piece, because the lower base plate 303 is needed to "push" the bamboo piece to rotate together.

[0050] Second, the bamboo pieces may collide in the flip frame unit 3 in a manner of falling over, ie, hitting the side panels 302 , which is normal.

[0051] Third, it is precisely the bamboo partitions that need to be removed, it is precisely the bamboo joint partitions that are located on the inner side of the curved cross-section of the bamboo piece, and it is precisely the bamboo piece with the green side facing up that needs to be turned over. If any of the above three points is missing, the bamboo piece cannot be turned over in a tilted manner.

[0052] That is, if the bamboo sheet needs to be flipped from the yellow side facing up to the green side facing up, the flipping operation of the self-tilting method is likely to fail, and the bamboo sheet with the yellow side facing up is likely to slide from the lower bottom plate 303 to the side plate 302, still with the yellow side facing up, after all, the green side is relatively slippery.

[0053] But it is different when the green side of the bamboo piece is facing upwards. At this time, the side of the bamboo piece can be firmly stuck in the angle between the lower bottom plate 303 and the side plate 302, so that it can tilt over instead of sliding over.

[0054] After the bamboo pieces with the green surface facing upward are flipped from the lower bottom plate 303 to one of the side plates 302 , the telescopic cylinder 2 can be used for conveying and discharging operations.

[0055] In this embodiment, if the bamboo pieces are determined to be loaded at the flip frame unit 3 in a falling manner, one of the side panels 302 is directly invalid.

[0056] The flip frame unit 3 further includes an upper connecting plate 304 disposed between the two side plates 302 .

[0057] In this embodiment, the upper connecting plate 304 is only used to reinforce the two side plates 302. Because the two side plates 302 need to apply force to clamp the two sides of one end of the bamboo piece, they are prone to deformation over time, that is, the opening becomes larger, and insufficient clamping may occur at this time. Therefore, it is very necessary to provide the upper connecting plate 304.

[0058] The protruding length of the lower base plate 303 on the end plate 301 is greater than that of the upper connecting plate 304 .

[0059] In this embodiment, when the bamboo piece flips over between the lower bottom plate 303 and the side plate 302 by itself, it needs to fall on the lower bottom plate 303, so the upper connecting plate 304 cannot be too long to block the falling or lowering action of the bamboo piece.

[0060] A discharging driving wheel 13 is provided on a side of the support platform 12 at a position different from the side where the mounting plate 11 is provided.

[0061] In this embodiment, when the bamboo chips are transported in the length direction, the transport power all comes from the lifting action of the telescopic cylinder 2. At this time, the problem of insufficient power may occur. Therefore, a rotating discharge drive wheel 13 is provided to ultimately ensure that the bamboo chips are smoothly transported out.

[0062] The support platform 12 is a lifting ring for inserting and placing bamboo pieces, or a conveyor belt for supporting the falling bamboo pieces.

[0063] In this embodiment, the bamboo pieces can be moved from the support platform 12 to the flip frame unit 3 in the following different ways.

[0064] 1. The lifting ring rises or falls, carrying and moving the bamboo piece steadily to the flip frame unit 3, and then the telescopic cylinder 2 is pushed inward, and the end of the bamboo piece smoothly enters the flip frame unit 3. At this time, the bamboo piece can be clamped and rotated at an obtuse angle, or the bamboo piece can be tilted and rotated at an acute angle.

[0065] 2. The height of the conveyor belt and the lower base 303 is roughly the same. The bamboo piece falls on the lower base 303 and the conveyor belt, and then the bamboo piece turns over by itself by tilting and rotating. Finally, the telescopic cylinder 2 is withdrawn, and the bamboo piece falls back slightly onto the conveyor belt, completing the turning.

[0066] 3. Derivative versions of the above two methods, such as a conveyor belt with a lifting structure, or a lifting ring that is a half ring with an upward opening, which can also allow bamboo pieces to be loaded on the lower base plate 303 and the half ring in a falling manner.

[0067] A sliding base 15 for arranging the mounting plate 11 is provided on the conveying device frame 14 .

[0068] In this embodiment, the conveying device frame 14 is a common, simple fixed frame structure, and the sliding base 15 includes an existing sliding hole plate and a sliding rod, which ultimately ensures that the starting position of the contraction action of the telescopic cylinder 2 is flexibly adjustable.

[0069] While the embodiments of the present invention have been described in detail above with reference to the accompanying drawings, the present invention is not limited to the aforementioned embodiments. Various modifications are possible within the scope of knowledge possessed by a person skilled in the art without departing from the spirit of the present invention. These modifications are non-inventive and are protected by patent law as long as they fall within the scope of the claims of the present invention.
