Description

Technical Field

[0001] This utility model relates to the field of bamboo product processing technology, specifically to a bamboo sawing device. Background Technology

[0002] Bamboo products refer to products made from bamboo as raw material. Bamboo products are increasingly used in daily life and production. When processing bamboo into products needed in our daily lives, the whole bamboo stalk needs to be sawn into multiple sections before being sent to a bamboo splitting machine to be split into strips of appropriate width. The bamboo strips are then further processed.

[0003] Chinese patent application CN114800699A discloses a raw bamboo sawing device, including a workbench. One side of the workbench is provided with a tip receiving platform for receiving the tips of raw bamboo. Both the workbench and the tip receiving platform are equipped with conveying devices for transporting the raw bamboo. The conveying device includes a conveyor chain and a drive mechanism for driving the conveyor chain to rotate. Several clamping mechanisms for fixing the raw bamboo are installed on the conveyor chain. The workbench has several sawing zones along the conveying direction of the raw bamboo, and each sawing zone is fixed with several... The patent application describes a sawing machine that, along the conveying direction of the raw bamboo, projects the sawing machine in the front sawing area onto the sawing machine in the rear sawing area. This design achieves phased cutting of the raw bamboo by layering the sawing areas along the conveying direction of the raw bamboo and utilizing the sawing machines within the sawing areas. This reduces the impact of the bamboo bending on the cutting process and improves cutting efficiency. However, since the sawing machines are fixedly installed within the sawing areas, the length of the cut bamboo tubes remains constant, making it impossible to quickly adjust the length of the cut bamboo. Utility Model Content

[0004] The main purpose of this utility model is to overcome the defects of the above-mentioned background technology and provide a bamboo sawing device.

[0005] To achieve the above objectives, the present invention proposes a bamboo sawing device, comprising a sawing frame with a conveying mechanism for transporting bamboo. The sawing frame is divided into several sawing zones, each containing a sawing mechanism. Each sawing mechanism includes a saw blade, a first motor, a tilting frame, a support frame, and a lifting cylinder. The first motor is mounted on the tilting frame, and the saw blade is connected to the output end of the first motor. The support frame is fixedly connected to the sawing frame. One side of the tilting frame is hinged to the support frame, and the other side is hinged to one end of the lifting cylinder. The other end of the lifting cylinder is also hinged to the support frame. The conveying mechanism transports the entire bamboo to be sawed horizontally and upward on the sawing frame. During transport, the bamboo can be sawn into multiple sections of the required length by multiple sawing mechanisms, effectively improving work efficiency. The lifting cylinder drives the tilting frame to tilt up or down, thereby raising or lowering the saw blade mounted on the tilting frame to adjust the sawing length of the bamboo and improve the efficiency of cutting the raw bamboo.

[0006] To further optimize the technical solution, a sliding groove is provided within the flipping frame, and a movable plate is slidably mounted within the groove. The first motor is fixedly mounted on the movable plate, and a lead screw is rotatably mounted on the flipping frame. The bottom of the movable plate is connected to the lead screw, and one end of the lead screw is connected to a second motor. The second motor drives the lead screw to rotate, causing the saw blade on the movable plate to move along the sliding groove to avoid cutting bamboo nodes or cracks in the outer wall of the bamboo. Simultaneously, the distance between two adjacent saw blades can be further adjusted to regulate the cut length of the bamboo.

[0007] To further optimize the technical solution, a laser detector corresponding to the position of the saw blade is installed on the movable plate. The laser detector detects damaged or cracked areas on the bamboo nodes or the outer wall of the bamboo, so that the saw blade can avoid cutting these areas.

[0008] To further optimize the technical solution, the conveying mechanism includes a conveyor chain and a drive mechanism for rotating the conveyor chain. Several baffles are installed on the conveyor chain to push the bamboo. When the conveyor chain rotates, the baffles block the bamboo to be sawed, preventing the bamboo from sliding backward.

[0009] To further optimize the technical solution, the sawing machine frame is equipped with a guide rod, and the guide rod has a chain guide groove. The conveyor chain's conveying stroke is slidably positioned within the chain guide groove. By slidably embedding the conveyor chain's conveying stroke into the chain guide groove, the conveyor chain is supported, preventing swaying during the transport of the bamboo to be sawed.

[0010] To further optimize the technical solution, the drive mechanism includes a third motor, a drive shaft, and a transmission sprocket assembly. The drive shaft is rotatably mounted on the end of the sawing frame. The transmission sprocket assembly is mounted on the drive shaft and the beginning of the sawing frame, respectively. The transmission chain is wrapped around the transmission sprocket assembly. The output end of the third motor is connected to the drive shaft.

[0011] To further optimize the technical solution, the bamboo sawing device also includes a bamboo root alignment mechanism, which is connected to the starting end of the sawing frame. The bamboo root alignment mechanism performs root alignment to ensure that the root of each bamboo stalk is in the same position relative to the first saw blade during the sawing process.

[0012] The technical solution is further optimized. The bamboo root alignment mechanism includes a fourth motor, an alignment chain, a limiting baffle, a conveying roller, and an alignment support frame. The conveying roller is rotatably connected to the alignment support frame. The limiting baffle is located at one end of the alignment support frame. The output end of the fourth motor is connected to the conveying roller through the alignment chain.

[0013] To further optimize the technical solution, a protective cover is provided at the alignment chain. This cover protects the alignment chain from being scraped or bumped when the bamboo is transferred to the bamboo root alignment mechanism, preventing the alignment chain from falling off and affecting the bamboo root alignment.

[0014] To further optimize the technical solution, a placement rack is connected to one side of the alignment support frame. The placement rack is horizontally aligned with the protective cover and is used to temporarily store the raw bamboo to be cut.

[0015] The beneficial effects of this utility model include: the conveying mechanism transports the whole bamboo to be cut laterally onto the sawing machine frame, and during the conveying process, the bamboo to be cut can be cut into multiple sections of bamboo tubes of the required length by multiple sets of sawing mechanisms, effectively improving work efficiency; the lifting cylinder drives the flipping frame to flip up or down, thereby driving the saw blade installed on the flipping frame to rise and fall, making it convenient to quickly adjust the cutting length of the bamboo and improve the cutting efficiency of the raw bamboo.

[0025] Please see Figures 1 to 4In one embodiment, a bamboo sawing device is disclosed, including a sawing frame 1. The sawing frame 1 is equipped with a conveying mechanism 2 for conveying bamboo stalks 6 to be sawed. The sawing frame 1 is inclined, and the entire bamboo stalk 6 is horizontally conveyed from the starting end (bottom end) to the ending end (top end) of the sawing frame 1 under the drive of the conveying mechanism 2. The sawing frame 1 is horizontally divided into several sawing zones 101, and each sawing zone 101 is equipped with a sawing mechanism 3. During the upward conveying of the bamboo stalk 6 on the sawing frame 1, it can be simultaneously cut into several bamboo sections by the sawing mechanism 3. The sawing mechanism 3 includes... The system includes a saw blade 301, a first motor 302, a tilting frame 303, a support frame 304, and a lifting cylinder 305. The first motor 302 is mounted on the tilting frame 303, and the saw blade 301 is connected to the output end of the first motor 302. The support frame 304 is fixedly connected to the bottom of the sawing machine frame 1. One side of the tilting frame 303 is hinged to the support frame 304, and the other side of the tilting frame 303 is hinged to one end of the lifting cylinder 305. The other end of the lifting cylinder 305 is hinged to the support frame 304. Specifically, the support frame 304 has an L-shaped structure when viewed from the side, and the tilting frame 303 is hinged to the top of the support frame 304. The top end of the lifting cylinder 305 is hinged to the free end of the flipping frame 303. When the lifting cylinder 305 extends to work, it can lift and flip the flipping frame 303, thereby driving the first motor 302 and saw blade 301 mounted on the flipping frame 303 to rise and fall. In this embodiment, the entire bamboo stalk 6 to be sawn is radially conveyed upward on the sawing frame 1 by the conveying mechanism 2. During the conveying process, the bamboo stalk 6 to be sawn can be sawn into multiple sections of bamboo tubes of the required length by multiple sets of sawing mechanisms 3, effectively improving work efficiency. The lifting cylinder 305 drives the flipping frame 303 to flip up or down, thereby driving the first motor 302 and saw blade 301 mounted on the flipping frame 303 to rise and fall. The saw blade 301 mounted on the flipping frame 303 and the first motor 302 are raised and lowered. When flipped up, the saw blade 301 can act on the corresponding part of the bamboo 6 to be cut and cut it. When flipped down, the saw blade 301 can be stored in the sawing frame 1 and cannot act on the bamboo 6 to be cut. Since a bamboo 6 to be cut is cut by multiple sets of different sawing mechanisms 3, by selecting the corresponding lifting cylinder 305 to drive the flipping frame 303 to flip up or down, a bamboo 6 to be cut can be cut into bamboo tube segments of different lengths at one time. It is also convenient to adjust the cutting length of the bamboo and improve the cutting efficiency of the raw bamboo.

[0026] In a preferred embodiment, a sliding groove 306 is provided on two opposite sides of the flip frame 303, and a movable plate 307 is slidably provided in the sliding groove 306. A first motor 302 is fixedly installed on the movable plate 307. A lead screw 308 is rotatably provided on the flip frame 303. The bottom of the movable plate 307 is connected to the lead screw 308. One end of the lead screw 308 is connected to a second motor 309. A laser detector 3010 corresponding to the position of the saw blade 301 is provided on the movable plate 307. Specifically, the laser detector 3010 is a device based on existing technology. The laser detector 3010 is located in front of the saw blade 301. Before the saw blade 301 is about to cut the bamboo 6 to be cut, it can detect the flatness of the length direction of the cutting part of the bamboo 6 to be cut, so as to determine whether there are bamboo nodes or cracks at the cutting part. Then, the second motor 309 drives the lead screw 308 to rotate. The lead screw drives the saw blade 301 on the moving plate 307 to move along the slide groove 306 to avoid bamboo nodes or cracks on the outer wall of the bamboo. At the same time, the second motor 309 drives the lead screw 308 to rotate. The lead screw drives the saw blade 301 on the moving plate 307 to move along the slide groove 306. The distance between two adjacent saw blades 301 can also be adjusted to further adjust the length of the bamboo tube segment at the cutting part.

[0027] In a specific example, the conveying mechanism 2 includes a conveyor chain 201 and a drive mechanism 202 that drives the conveyor chain 201 to rotate. Several baffles 203 for pushing the bamboo are installed on the conveyor chain 201. After the entire bamboo 6 to be sawed is horizontally sent to the bottom of the sawing frame 1, it is blocked and jammed on the conveyor chain 201 by the baffles 203, and then conveyed upward by the conveyor chain 201 to the sawing mechanism 3 for cutting.

[0028] In a preferred embodiment, a guide rod 102 is provided on the sawing frame 1. The guide rod 102 is arranged on the upper surface of the sawing frame 1 along the conveying direction of the bamboo 6 to be sawed. A chain guide groove 103 is formed on the guide rod 102, and the conveying chain 201 slides into the chain guide groove 103. The guide rod 102 supports the conveying chain 201, preventing it from shaking during the conveying of the bamboo 6 to be sawed.

[0029] In a specific example, the drive mechanism 202 includes a third motor 2021, a drive shaft 2022, and a transmission sprocket set 2023. The drive shaft 2022 is rotatably mounted on the end of the sawing frame 1. The transmission sprocket sets 2023 are respectively mounted on the drive shaft 2022 and the beginning of the sawing frame 1. The transmission chains 201 are respectively wrapped around the transmission sprocket sets 2023. The output end of the third motor 2021 is connected to the drive shaft 2022. Specifically, the third motor 2021 can drive the drive shaft 2022 to rotate using any of the following transmission methods: chain drive, belt drive, or gear drive. It is preferred to use chain drive. The third motor 2021 is fixed on one side of the sawing frame 1 and drives the drive shaft 2022 to rotate via chain drive. All the transmission sprocket sets 2023 on the drive shaft 2022 rotate synchronously, thereby driving all the transmission chains 201 to rotate synchronously, so as to synchronously transport the bamboo 6 to be sawed to the sawing mechanism 3 for sawing.

[0030] In one embodiment, the bamboo sawing device also includes a bamboo root alignment mechanism 4, which is connected to the starting end of the sawing frame 1. Before the bamboo 6 to be sawed enters the sawing frame 1, it enters the bamboo root alignment mechanism 4 for root alignment to ensure that the root of each bamboo is in the same position relative to the first saw blade 301 during the sawing operation, thereby improving the utilization rate of bamboo.

[0031] In a specific example, the bamboo root alignment mechanism 4 includes a fourth motor 401, an alignment chain 402, a limiting baffle 403, a conveying roller 404, and an alignment support frame 405. The conveying roller 404 is rotatably connected to the alignment support frame 405. The limiting baffle 403 is located at one end of the alignment support frame 405. The output end of the fourth motor 401 is connected to the conveying roller 404 via the alignment chain 402. A protective cover 406 is provided at the alignment chain 402 to cover it and prevent the bamboo from scratching the alignment chain 402. A placement frame 5 is connected to one side of the alignment support frame 405. The placement frame 5 is horizontally aligned with the protective cover 406 to prevent the bamboo from scratching the bamboo. When the bamboo 6 to be cut on the rack 5 moves to the bamboo root alignment mechanism 4, it gets stuck. The bamboo 6 to be cut is temporarily placed on the rack 5. When feeding, the bamboo 6 to be cut is pushed onto the bamboo root alignment mechanism 4. The fourth motor 401 drives the alignment chain 402 to drive the first conveyor roller 404 to rotate. The two adjacent conveyor rollers 404 are connected to each other through another alignment chain 402, so that all the conveyor rollers 404 can be rotated synchronously, thereby driving the bamboo 6 to be cut to move towards its root. When the root of the bamboo 6 to be cut moves to the limit baffle 403, it stops moving and is then conveyed by the conveying mechanism 2 to the sawing frame 1 for sawing.
