Description

Technical Field

[0001] The invention relates to the technical field of bamboo material processing, in particular to a bamboo sawing machine. Background Art

[0002] The first processing step after the raw bamboo enters the factory is bamboo sawing, which is to cut the raw bamboo into equal length bamboo segments. At present, bamboo sawing is still done by manually placing the raw bamboo on the bamboo sawing machine. The more advanced bamboo sawing machines can automatically drag the raw bamboo to saw it. Because there are bamboo nodes and the distance between the bamboo nodes on each bamboo is different, the existing bamboo sawing machines usually saw the bamboos one by one.

[0003] In order to improve operating efficiency and labor costs, bamboo sawing machines and bamboo splitting machines (used to split bamboo segments into bamboo strips) are integrated together to achieve continuous operations of bamboo sawing and bamboo splitting, which is the trend of raw bamboo processing. At present, the bamboo splitting efficiency of bamboo splitting machines has been greatly improved. Under the premise of sufficient supply, bamboo splitting machines can split 10 to 12 bamboo segments per minute. In the past, when bamboo sawing and bamboo splitting operations were separated, bamboo sawing buffers could be prepared first to meet the needs of bamboo splitting. However, because a raw bamboo generally needs to be sawed off many times, and it is necessary to identify and avoid bamboo nodes, it generally takes 20 to 30 seconds to saw off a raw bamboo, and the number of bamboo segments sawed out is generally 4 to 6. In addition to the transition time from raw bamboo feeding to bamboo sawing machines, the current bamboo segment output efficiency of bamboo sawing machines is generally 8 to 10 sections per minute. Therefore, after the integration of bamboo sawing and bamboo splitting, the current bamboo sawing machine efficiency cannot meet the needs of bamboo splitting machines, so it is urgent to develop a more efficient bamboo sawing machine.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0027] like Figures 1 to 8 As shown, the present invention discloses a bamboo sawing machine, which includes: a frame 10, a sawing device, a conveying device, a visual detector and a controller.

[0028] Two feeding channels 11 are arranged side by side on one side of the frame 10, and the two feeding channels 11 are as close to each other as possible. The feeding channel 11 is designed to have a guiding function. Specifically, the width of the feeding channel 11 decreases along the advancing direction of the raw bamboo to form a gradually narrowing guiding channel, so that the raw bamboo leaving the feeding channel 11 can be directed to the conveying device. In order to ensure the realization of the guiding function and to provide a good support for the raw bamboo, the feeding channel 11 needs to have a certain length.

[0029] The visual detector is used to identify bamboo nodes. The visual detector is arranged on the frame 10. Each feeding channel 11 corresponds to a visual detector, or two feeding channels 11 share a visual detector. The visual detector is connected to the controller.

[0030] Each feed channel 11 corresponds to a conveying device, and the two sets of conveying devices are independent of each other. The conveying device is located on the outlet side of the feed channel 11. The conveying device includes a conveying mechanism 20 and a clamping mechanism 30. The inlet end of the conveying mechanism 20 is adjacent to the outlet of the feed channel 11. The length direction of the feed channel 11 is consistent with the conveying direction of the conveying mechanism 20, and the feed channel 11 is centered on the conveying mechanism 20.

[0031] The conveying mechanism 20 includes a conveying motor 21, two sets of first conveying assemblies 22 and a plurality of pallets 23. The conveying motor 21 is connected to the controller. The first conveying assemblies 22 are arranged side by side, and include a first sprocket 221, a second sprocket 222 and a first chain 223. The first connecting rod 12 and the second connecting rod 13 are rotatably connected on the frame 10. The first sprockets 221 corresponding to the two sets of first conveying assemblies 22 are all installed on the first connecting rod 12 and rotate synchronously with the first connecting rod 12. The second sprockets 222 corresponding to the two sets of first conveying assemblies 22 are all installed on the second connecting rod 13 and rotate synchronously with the second connecting rod 13. The first chain 223 connects the corresponding first sprocket 221 and the second sprocket 222. The conveying motor 21 drives the first connecting rod 12 to rotate.

[0032] The supporting plate 23 is connected to two first chains 223 at the same time, and the supporting plates 23 are arranged at equal intervals on the first chains 223. The supporting plate 23 includes a connecting portion 231 and a supporting portion 232, wherein the connecting portion 231 is connected to the first chains 223, and the supporting portion 232 is provided with a limiting groove 233 for limiting the original bamboo, wherein the groove width of the limiting groove 233 increases from the groove bottom toward the groove opening, and an anti-slip tooth portion 234 is provided at the groove bottom of the limiting groove 233. In particular, the angle A between the connecting portion 231 and the supporting portion 232 is 30 to 60°, preferably 45°. When the support plate 23 moves toward the forward direction of the raw bamboo, the opening direction of the angle between the connecting portion 231 and the supporting portion 232 is toward the discharge direction of the raw bamboo. After this arrangement, the end of the raw bamboo is not prone to getting stuck when transitioning from the feed channel 11 to the conveying mechanism 20, thereby ensuring a smooth transition. Moreover, after the support plate 23 is arranged in this way, the supporting portion 232 can also generate a force to push the raw bamboo in the discharge direction, which is beneficial to the transportation of the raw bamboo.

[0033] In order to ensure that the support plate 23 (i.e., the mop 23 located on the first conveying assembly 22) moving in the forward direction of the raw bamboo can effectively contact the raw bamboo, a support member 14 supporting the first chain 223 or the support plate 23 is provided on the frame 10. Preferably, the support member 14 supports the first chain 223, and the middle position of the first chain 223 has a groove, and the support member 14 abuts against the groove. This arrangement can also prevent the middle section of the first chain 223 from swinging left and right (seen along the forward direction of the raw bamboo), ensuring the smooth transportation of the raw bamboo. A guide portion is provided at one end of the support member 14 close to the feed channel 11, and the guide portion can be a slope. By providing the guide portion, the support member 14 can be prevented from getting stuck with the first chain 223 or the support plate 23.

[0034] The clamping mechanism 30 is placed above the conveying mechanism 20, and includes a clamping drive 31, a clamping assembly 32 and a second conveying assembly 33. The clamping drive 31 is a linear cylinder, and the clamping drive 31 is connected to a controller.

[0035] The clamping assembly 32 includes two groups of swinging members 321 and a clamping frame 322. One end of the swinging member 321 is rotatably connected to the frame 10 through a rotating shaft 323, and the other end of one swinging member 321 is rotatably connected to one end of the clamping frame 322 through a first connecting shaft 324, and the other end of the other swinging member 321 is rotatably connected to the other end of the clamping frame 322 through a second connecting shaft 325. The base of the clamping driving member 31 is rotatably connected to the frame 10, and the movable part of the clamping driving member 31 is rotatably connected to the middle section of the clamping frame 322. After the clamping driving member 31 is actuated, it can push the clamping frame 322 to move relative to the first conveying assembly 22, thereby clamping the raw bamboo transported on the first conveying assembly 22 to ensure that the raw bamboo will not tilt when the sawing device is sawing the bamboo. In addition, with the clamping mechanism 30 configured in this way, the two ends of the clamping frame 322 can be staggered to a certain extent, and the diameter of the original bamboo is gradually changed, so the clamping frame 322 can fit the original bamboo more closely, and the bottom surface of the clamping frame 322 can basically contact the original bamboo, ensuring that the original bamboo is reliably clamped.

[0036] The second transmission assembly 33 is arranged on the pressing frame 322, and multiple groups of the second transmission assembly 33 are arranged and arranged at intervals on the pressing frame 322. The second transmission assembly 33 and the first transmission assembly 22 act synchronously but turn in opposite directions. The cooperation of the two can make the raw bamboo transportation smoother, and can realize the transportation of the raw bamboo while clamping it, thereby ensuring that the cuts of the sawed bamboo segments tend to be consistent. Specifically, the second transmission assembly 33 includes a third sprocket 331, a fourth sprocket 332 and a second chain 333. The third sprocket 331 is locked on the first connecting shaft 324, the fourth sprocket 332 is locked on the second connecting shaft 325, and the second chain 333 connects the third sprocket 331 and the fourth sprocket 332. The second chain 333 is used to assist in driving the raw bamboo transportation. Anti-skid teeth 334 can be evenly arranged on the second chain 333 to prevent slipping. At the same time, when the pressing mechanism 30 presses the raw bamboo, the raw bamboo will be placed between the two second chains 333, which can further prevent the raw bamboo from sliding sideways, thereby ensuring the sawing operation.

[0037] The second transmission assembly 33 can be independently provided with a power drive member, or can be linked with the first transmission assembly 22, and the latter is preferred to simplify the equipment structure and cost. The linkage system of the first transmission assembly 22 and the second transmission assembly 33 can be: a first connecting wheel 34 is provided on the first connecting shaft 324, a second connecting wheel 35 and a third connecting wheel 36 are provided on the rotating shaft 323 corresponding to the swinging member 321 connected to the first connecting shaft 324, a fourth connecting wheel 15 and a first reversing wheel 16 are rotatably connected on the frame 10, the fourth connecting wheel 15 and the first reversing wheel 16 are coaxially arranged and rotate synchronously, a second reversing wheel 17 is provided on the first connecting rod 12, the first connecting wheel 34 and the second connecting wheel 35 are chain-connected, the third connecting wheel 36 and the fourth connecting wheel 15 are chain-connected, and the first reversing wheel 16 and the second reversing wheel 17 are meshed. After such a setting, the swinging of the swinging member 321 will not interfere with the operation of the linkage system.

[0038] The sawing device is arranged on a side of the frame 10 away from the feeding channel 11 , and comprises a driving mechanism and a sawing mechanism 50 . The driving mechanism drives the sawing mechanism 50 to move up and down relative to the frame 10 .

[0039] The driving mechanism includes a mounting frame 41, a pull rod 42, a swing arm 43 and a rotating power assembly 44. The middle section of the mounting frame 41 is rotatably connected to the frame 10, one end of the mounting frame 41 is rotatably connected to one end of the pull rod 42, the other end of the pull rod 42 is rotatably connected to one end of the swing arm 43, and the output shaft of the rotating power assembly 44 is rotatably connected to the other end of the swing arm 43. The rotating power assembly 44 is a motor, or the rotating power assembly 44 is a combination of a motor and a gearbox, preferably the latter. The motor is connected to a controller.

[0040] The sawing mechanism 50 includes a sawing motor 51, a transmission shaft 52 and a saw blade 53. The base of the sawing motor 51 is arranged at one end of the mounting frame 41 connected to the pull rod 42, the transmission shaft 52 is rotatably connected to the end of the mounting frame 41 away from the pull rod 42, the output shaft of the sawing motor 51 is transmission-connected to one end of the transmission shaft 52, and the saw blade 53 is detachably connected to the other end of the transmission shaft 52. The saw blade 53 can saw the raw bamboo output by the two conveying mechanisms 20 at the same time.

[0041] The worker pushes the big end of the raw bamboo into the feeding channel 11, and the big end of the raw bamboo can be sensed by the visual detector (or, an infrared sensor can be set to sense the position of the raw bamboo). In order to facilitate the worker to know that the raw bamboo is pushed into place, an indicator light can be set on the frame 10 to inform, and the indicator light is connected to the controller. The raw bamboo is placed in the photographing range of the visual detector, and the first bamboo node (the frontmost bamboo node) is identified. By setting a relative reference line, the distance between the relative reference line and the saw blade 53 can be the length of the bamboo segment to be obtained, thereby determining the distance between the first bamboo node and the saw blade 53. The conveying device conveys the raw bamboo so that the first bamboo node is placed at the front end (i.e., the first bamboo node does not exceed the saw blade 53) or the rear end (i.e., the first bamboo node exceeds the saw blade 53) of the saw blade 53. When the first bamboo node is placed at the front end of the saw blade 53, it means that there is a large distance between the first bamboo node and the felling opening. When the first bamboo node is placed at the rear end of the saw blade 53, it means that the distance between the first bamboo node and the felling opening is too short. This can be determined when the first bamboo node is identified, and the distance that the conveying device needs to move the raw bamboo can also be determined. After the raw bamboo is moved into place, the sawing device operates once. At the same time, it identifies whether there is a bamboo node in the raw bamboo relative to the reference line. Otherwise, the raw bamboo is moved to a fixed length and sawed off. If so, the moving distance of the raw bamboo is re-determined based on the surplus length of the first bamboo node relative to the end, and then it is sawed off, and this is repeated. Visual inspection technology is a prior art and will not be described in detail in this case.

[0042] The conveying device corresponding to the feed channel 11 that is loaded with raw bamboo for the first time is defined as the main conveying device, and the other conveying device is the auxiliary conveying device, and the main conveying device operates normally in the above manner. The feed channel 11 corresponding to the auxiliary conveying device normally performs bamboo joint identification and distance judgment, but the action of the auxiliary conveying device cannot interfere with the operation of the main conveying device, that is, when the raw bamboo on the main conveying device is sawed, the auxiliary conveying device cannot operate to avoid damage to the saw blade 53. This should be paid special attention to when the main channel is in the bamboo sawing operation state and the auxiliary channel is in the new loading state. Of course, when both the main and auxiliary channels are in the bamboo sawing operation state, the sawing device can also wait until both sets of conveying devices move the raw bamboo into place before moving, and the waiting time is very short and has almost no effect. When the raw bamboo on the main conveying device is exhausted, the main and auxiliary are transposed. In the actual operation process, try to avoid running out of two raw bamboos at the same time to avoid workers loading raw bamboos more hastily. When the raw bamboo in the main channel is sawed off by about half, the raw bamboo can be loaded into the auxiliary channel.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
