Description

Technical Field

[0001] This utility model relates to the field of bamboo processing technology, and in particular to a bamboo tube measuring device. Background Technology

[0002] The processing steps from raw bamboo to bamboo strips generally include sawing, diameter measurement, and splitting. After the raw bamboo is sawn into bamboo tubes, the inner and outer diameters and wall thickness of the tubes need to be measured to select the appropriate splitting blade set. Previously, raw bamboo was sawn into equal-length bamboo tubes, and bamboo splitting machines could typically only split bamboo tubes of fixed lengths. However, the market demand for bamboo products varies greatly; for example, bamboo chopsticks (including disposable chopsticks) come in various lengths. To adapt to market demands, raw bamboo processing plants have placed higher requirements on bamboo splitting machines. Utility Model Content

[0003] The purpose of this invention is to provide a bamboo tube measuring device that can quickly detect the length of bamboo tubes, thereby enabling the bamboo splitting machine to adapt to splitting bamboo tubes of different lengths.

[0004] To achieve the above objectives, this utility model discloses a bamboo tube measuring device, which includes a frame, a stop plate, a push plate, a first driving mechanism, and a distance measuring element for measuring the moving distance of the push plate or the distance between the push plate and the stop plate. The frame is equipped with a placement rack for placing bamboo tubes. The stop plate is located at one end of the placement rack, and the push plate is located at the other end. The first driving mechanism drives the push plate to move relative to the stop plate, and the push plate can extend into the placement rack. With this configuration, the push plate, driven by the first driving mechanism, can push the bamboo tubes on the placement rack until they abut against the stop plate. At this point, the distance between the stop plate and the push plate is the length of the bamboo tube. Alternatively, as long as the starting position of the push plate remains constant, measuring the moving distance of the push plate can also quickly obtain the length information of the bamboo tube (the distance from the starting position of the push plate to the stop plate minus the moving distance of the push plate is the length of the bamboo tube).

[0005] Preferably, the first drive mechanism includes a first motor, a traveling gear, and a first rack. The first rack is mounted on the frame, the traveling gear meshes with the first rack, the first motor is slidably connected to the frame, and the first motor drives the traveling gear to rotate; the push plate is connected to the base of the first motor. Alternatively, the first driving mechanism includes a second motor, a screw, a guide member, and a slider. The screw and the guide member are parallel to each other, the slider is slidably connected to the guide member, and the slider is threadedly connected to the screw. The second motor is mounted on the frame and drives the screw to rotate. The push plate is connected to the slider. Alternatively, the first drive mechanism includes at least one first cylinder, which are connected in series, with the first cylinder at the beginning connected to the frame and the first cylinder at the end connected to the push plate. The above provides three forms of first drive mechanisms, all of which are simple in structure and easy to assemble and maintain.

[0006] Preferably, both the first and second motors are stepper motors or servo motors, which serve as ranging elements; alternatively, the ranging element is an encoder or a rotary transformer, and the ranging element is connected to the first or second motor. The distance the push plate moves corresponding to one revolution of the motor is fixed; therefore, the moving distance of the push plate can be calculated by measuring the motor's revolutions. Stepper motors have built-in angular or linear displacement detection, which can determine their revolutions, and using stepper motors simplifies the device structure. The motor revolutions can also be calculated using encoders and rotary transformers; by configuring encoders and rotary transformers, ordinary motors can be used for both the first and second motors.

[0007] Preferably, when the first drive mechanism includes a first cylinder, a synchronous gear is rotatably connected to the push plate, and a second rack meshing with the synchronous gear is provided on the frame; the ranging element is an encoder or a rotary transformer, and the ranging element is connected to the synchronous gear. The distance the push plate moves for one revolution of the synchronous gear corresponds to a fixed distance the push plate moves. The number of revolutions of the synchronous gear can be determined by the encoder and the rotary transformer, thereby calculating the moving distance of the push plate. In addition, this configuration also has the advantages of simple structure and low cost.

[0008] Preferably, the ranging element is a grating ruler, the ruler body of which is connected to the frame, and the reading head of the grating ruler is connected to a push plate; or, the ranging element is a laser rangefinder or an infrared rangefinder, which is connected to the push plate or a stop plate; or, the ranging element is a ranging wheel, which is connected to the push plate and abuts against the frame; or, the ranging element is an industrial camera. Various types of ranging elements are provided, offering users diverse choices.

[0009] Preferably, it also includes a unloading mechanism for removing the bamboo tubes from the placement rack. By providing an unloading mechanism to facilitate the removal of the bamboo tubes from the measuring device, operational efficiency is improved.

[0010] Preferably, the unloading mechanism includes a first unloading drive assembly that drives the placement frame to rotate; or, the unloading mechanism includes a second unloading drive assembly and at least one pusher for pushing the bamboo tubes out of the placement frame, the pusher being placed in the placement frame, or the pusher being able to extend into the placement frame, the placement frame having a clearance opening for avoiding the pusher, and the second unloading drive assembly driving the pusher to move; or, the unloading mechanism is a robotic arm. Multiple unloading structures are provided, offering more options for adapting measuring devices to build bamboo splitting machines.

[0011] Preferably, it also includes a lateral drive assembly for moving the placement rack relative to the stop plate. By providing the lateral drive assembly, the push plate can be assisted in aligning the bamboo tube with the stop plate. In addition, after the bamboo tube has been inspected, it can also be moved a certain distance away from the stop plate, which is beneficial for unloading.

[0012] Preferably, the unloading mechanism includes a first unloading drive assembly, which drives the placement frame to rotate; The first unloading drive assembly includes a second cylinder and a swing arm; the lateral drive assembly includes a third cylinder; a slide rod is rotatably connected to the frame, one end of the swing arm is connected to the slide rod, and the slide rod rotates synchronously with the swing arm, the other end of the swing arm is rotatably connected to the push rod of the second cylinder, and the seat of the second cylinder is rotatably connected to the frame; the placement frame is slidably connected to the slide rod, the seat of the third cylinder is connected to the placement frame, and the push rod of the third cylinder is connected to the slide rod; Alternatively, the first unloading drive assembly includes a fourth cylinder; the traverse drive assembly includes a fifth cylinder and a traverse frame; the traverse frame is slidably connected to the machine frame, the seat of the fifth cylinder is connected to the machine frame, and the push rod of the fifth cylinder is connected to the traverse frame; the placement frame is rotatably connected to the traverse frame, the seat of the fourth cylinder is rotatably connected to the traverse frame, and the push rod of the fourth cylinder is rotatably connected to one side of the placement frame. The above provides two ways of cooperating the first unloading drive assembly and the traverse drive assembly, allowing users to flexibly choose to adapt and assemble a bamboo splitting machine.

[0013] Preferably, the device further includes a bamboo tube diameter measuring mechanism and a stop plate moving assembly. The bamboo tube diameter measuring mechanism is located at the end of the stop plate away from the push plate; the stop plate moving assembly drives the stop plate to move. After the bamboo tube length measurement is completed, the stop plate moving assembly drives the stop plate to move, which frees up space for the bamboo tube diameter measuring mechanism to facilitate diameter measurement of the bamboo tube end. Integrating length measurement and diameter measurement into one device can improve measurement efficiency, thereby improving the operating efficiency of the bamboo splitting machine.

[0014] Preferably, the device also includes a bamboo tube centering mechanism, which is located between the placement frame and the stop plate. The bamboo tube centering mechanism helps improve the accuracy of diameter measurement.

[0015] Preferably, the system further includes a detection element for detecting the position of the bamboo tube end. This detection element is located between the stop plate and the placement frame, and is spaced apart from the stop plate. By detecting the position of the bamboo tube end, a signal is obtained indicating that the bamboo tube is about to contact the stop plate. This signal, in conjunction with the operation of the first drive mechanism, can provide an early warning, instructing the first drive mechanism to decelerate and thus avoid significant impact on the stop plate. In actual operation, the first drive mechanism can initially operate at high speed, and then decelerate when it receives the signal from the detection element, thereby improving the efficiency of measuring the bamboo tube length.

[0016] Preferably, the placement rack has a long groove in which the bamboo tube is placed. By setting a continuous long groove for placing the bamboo tube, it can be ensured that the bamboo nodes will not interfere with its movement, and that the bamboo tube can be pushed smoothly (if the long groove is not continuous, the bamboo nodes may get stuck with the discontinuous positions of the placement rack, affecting the movement of the bamboo nodes).

[0017] This utility model also discloses a bamboo splitting machine, which adopts the aforementioned bamboo tube measuring device; the bamboo splitting machine also includes a controller, which is connected to the bamboo tube measuring device. By controlling the operation of the bamboo tube measuring device through the controller, the operation of other devices of the bamboo splitting machine can be better coordinated. In addition, the bamboo tube measuring device can provide feedback on the length of the bamboo tube, providing data support for subsequent bamboo tube splitting operations (for bamboo tubes of different lengths, the moving distance for splitting is different), ensuring that the bamboo tube splitting can be completed smoothly, thereby ensuring that the bamboo splitting machine can adapt to the splitting and processing of bamboo tubes of different lengths.

[0018] This utility model has the following beneficial effects: This invention uses a first driving mechanism to move a push plate, which pushes the bamboo tubes on the placement rack until they abut against a stop plate. The distance between the stop plate and the push plate at this point is the length of the bamboo tube. Alternatively, by ensuring the push plate's initial position remains constant, measuring the distance the push plate travels can quickly obtain the bamboo tube's length. Controlling the bamboo tube measuring device via the bamboo splitting machine's controller allows for better coordination with other components of the machine. Furthermore, the bamboo tube measuring device provides feedback on the bamboo tube's length, offering data support for subsequent bamboo tube splitting operations and ensuring smooth completion of the splitting process. This allows the bamboo splitting machine to adapt to bamboo tubes of different lengths. Attached Figure Description Figure 1 This is a schematic diagram of Example 1.

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0035] Example 1 like Figure 1-5 As shown, this embodiment discloses a bamboo tube measuring device, which includes a frame 10, a stop plate 20, a push plate 30, a first driving mechanism, a distance measuring element for measuring the moving distance of the push plate 30 or measuring the distance between the push plate 30 and the stop plate 20, a unloading mechanism, a transverse driving assembly, a bamboo tube diameter measuring mechanism 82 and a stop plate moving assembly 83, a bamboo tube centering mechanism 84 and a detection element 81.

[0036] A placement rack 11 for placing bamboo tubes 100 is provided on the frame 10. The placement rack 11 can be concave to facilitate the reliable placement of bamboo tubes 100. In this embodiment, the placement rack 11 has a continuous, uninterrupted long groove 13 in which the bamboo tubes 100 are placed. The long groove 13 facilitates the stable placement of bamboo tubes 100 of different lengths. In addition, the smooth inner wall of the long groove 13 will not interfere with the bamboo nodes on the bamboo tubes 100, allowing the bamboo tubes 100 to be pushed more smoothly. A stop plate 20 is located at one end of the placement rack 11 along its length, and a push plate 30 is located at the other end of the placement rack 11 along its length. The push plate 30 can extend into the placement rack 11 to ensure that shorter bamboo tubes 100 can be pushed.

[0037] A lateral movement drive assembly is used to drive the placement rack 11 to move along its length. The unloading mechanism includes a first unloading drive assembly, which drives the placement rack 11 to rotate, thereby allowing the opening of the long trough 13 to rotate from a vertical orientation to an inclined or horizontal orientation, thus emptying the bamboo tubes 100 therein. Specifically, in this embodiment, the first unloading drive assembly includes a second cylinder 41 and a swing arm 42. The lateral movement drive assembly includes a third cylinder 51. A slide rod 12 is rotatably connected to the frame 10, one end of the swing arm 42 is connected to the end of the slide rod 12, and the slide rod 12 rotates synchronously with the swing arm 42. The other end of the swing arm 42 is rotatably connected to the push rod of the second cylinder 41, and the seat of the second cylinder 41 is rotatably connected to the frame 10. The placement rack 11 is slidably connected to the slide rod 12. In this embodiment, the placement rack 11 has a sleeve 14, which is fitted onto the slide rod 12, thereby enabling the placement rack 11 to slide relative to the slide rod 12. To improve sliding performance, multiple rollers 15 are rotatably connected to both ends of the sleeve 14, and the wheel surfaces of the rollers 15 press against the slide rod 12. The seat of the third cylinder 51 is bolted to the placement rack 11, and the push rod of the third cylinder 51 is connected to the slide rod 12. When the second cylinder 41 is extended, the opening of the long groove 13 faces upward, and the bamboo tube 100 can be stably placed in the long groove 13. When the second cylinder 41 is retracted, the opening of the long groove 13 turns to the horizontal, and the bamboo tube 100 can be poured out. When the third cylinder 51 is activated, the bamboo tube 100 can move closer to or further away from the stop plate 20.

[0038] In this embodiment, the first driving mechanism includes a first motor 61, a traveling gear 62, and a first rack 63. The first rack 63 is mounted on the frame 10, and the traveling gear 62 meshes with the first rack 63. The first motor 61 is slidably connected to the frame 10 via a guide assembly, which consists of a guide rail 64 and a guide block 65. The guide block 65 is slidably connected to the guide rail 64, and the guide rail 64 restricts the guide block 65 to detach only from the end of the guide rail 64. The first motor 61 is connected to the guide block 65. The first motor 61 drives the traveling gear 62 to rotate, and the push plate 30 is connected to the base of the first motor 61. In this way, when the first motor 61 rotates, the push plate 30 can move along the length direction of the guide rail 64. The length direction of the guide rail 64 is parallel to the length direction of the long groove 13. By driving the push plate 30 to move through the first driving mechanism, the push plate 30 can push the bamboo tube 100 on the placement rack 11 until it abuts against the stop plate 20. At this time, the distance between the stop plate 20 and the push plate 30 is the length of the bamboo tube 100.

[0039] In this embodiment, the first motor 61 is a stepper motor or a servo motor. Both stepper motors and servo motors have built-in angular displacement or linear displacement detection, which allows the determination of their rotation number. The distance the push plate 30 moves corresponding to one rotation of the motor is fixed. Therefore, the moving distance of the push plate 30 can be calculated by counting the number of rotations of the motor. In this embodiment, the first motor 61 also functions as a distance measuring element. When the push plate 30 is reset, that is, when the push plate 30 is in the starting position (the position with the greatest distance from the push plate 30 to the stop plate 20 can be selected as the starting position), the distance between the push plate 30 and the stop plate 20 is a fixed value. Therefore, the distance from the starting position of the push plate 30 to the stop plate 20 minus the moving distance of the push plate 30 is the length of the bamboo tube 100.

[0040] The detection element 81 is located between the stop plate 20 and the placement rack 11, with a certain distance between them. The detection element 81 is used to detect the position of the bamboo tube 100's end. By detecting the position of the bamboo tube 100's end, a signal is obtained indicating that the bamboo tube 100 is about to contact the stop plate 20. This signal, in conjunction with the operation of the first motor 61, can provide an early warning, informing the first motor 61 to decelerate, thereby avoiding significant impact on the stop plate 20. In actual operation, the first motor 61 can initially operate at high speed, allowing the bamboo tube 100 to quickly approach the stop plate 20. When the detection element 81 detects the end of the bamboo tube 100, the first motor 61 decelerates, thus improving the efficiency of measuring the length of the bamboo tube 100. The detection element 81 can be a grating, a contact switch, or a pressure sensor, etc. This illustration uses a grating as an example for the detection element 81.

[0041] The bamboo tube diameter measuring mechanism 82 is located at the end of the stop plate 20 away from the push plate 30. The bamboo tube diameter measuring mechanism 82 is existing technology; for example, it can be a bamboo diameter measuring device with publication number CN218524101U or a measuring device with publication number CN116538891A. Alternatively, visual inspection can be used to obtain the diameter and wall thickness of the bamboo tube 100. The bamboo tube diameter measuring mechanism 82 is not the focus of this case and will not be elaborated upon. To prevent the stop plate 20 from obstructing the operation of the bamboo tube diameter measuring mechanism 82, a stop plate moving assembly 83 is provided to drive the stop plate 20 to move, thereby allowing the stop plate 20 to be moved aside, freeing up working space for the bamboo tube diameter measuring mechanism 82. The stop plate moving assembly 83 can be a cylinder. Under normal conditions, the cylinder extends, and the stop plate 20 can block the bamboo tube 100. After the length of the bamboo tube 100 is measured, the cylinder retracts, and the stop plate 20 moves downward to make room. By integrating length and diameter measurements into a single device, measurement efficiency can be improved, thereby increasing the operational efficiency of the bamboo splitting machine. Furthermore, to ensure smooth and accurate diameter measurement, a bamboo tube centering mechanism 84 is provided, located between the placement frame 11 and the stop plate 20. The bamboo tube centering mechanism 84 is also existing technology; for example, it can utilize the centering clamp arm in the measuring device with publication number CN116538891A. The bamboo tube centering mechanism 84 is not the focus of this case and will not be elaborated upon further.

[0042] The working principle of this embodiment is as follows: Bamboo tube 100 is loaded onto the placement rack 11, the stop plate 20 rises, and then the lateral drive assembly drives the placement rack 11 to move towards the stop plate 20, providing auxiliary movement. Simultaneously, the first drive mechanism pushes the push plate 30 at high speed. When the detection element 81 detects the end of the bamboo tube 100, the first motor 61 decelerates and enters torque control mode. If the torque exceeds the set value, it indicates that the bamboo tube 100 has reached the stop plate 20, and the first motor 61 stops. At this time, the number of revolutions of the first motor 61 is recorded, and the length of the bamboo tube 100 can be calculated. Afterwards, the stop plate 20 descends, and the bamboo tube centering mechanism 84 centers the bamboo tube 100. After centering, the bamboo tube diameter measuring mechanism 82 begins to measure the diameter. After the diameter measurement is completed, the first motor 61 drives the push plate 30 to reset, and simultaneously, the lateral drive assembly drives the placement rack 11 to move towards the push plate 30, ensuring that the end of the bamboo tube 100 does not collide with the bamboo tube centering mechanism 84. Then the first unloading drive component is activated, the bamboo tube 100 is poured out, and the first unloading drive component is reset, thus completing one dimensional measurement of the bamboo tube 100.

[0043] Example 2 The difference between this embodiment and Embodiment 1 lies in the adjustment of the structure of the first driving mechanism. Specifically, as follows: Figure 6As shown, in this embodiment, the first driving mechanism includes a second motor 66, a screw 67, a guide member 68, and a slider 69. The screw 67, guide member 68, and elongated groove 13 are parallel to each other. The guide member 68 can be a guide rail or a smooth rod. The slider 69 is slidably connected to the guide member 68, and the slider 69 is threadedly connected to the screw 67. The second motor 66 is mounted on the frame 10, and the second motor 66 drives the screw 67 to rotate. The push plate 30 is connected to the slider 69. The second motor 66 is the same as the first motor 61, and can be a stepper motor or a servo motor.

[0044] Example 3 The difference between this embodiment and Embodiments 1 and 2 is that both the first motor 61 and the second motor 66 are ordinary motors, meaning they are no longer used as ranging elements. The ranging element is an encoder 71 or a rotary transformer. Taking the encoder 71 or rotary transformer connected to the first motor 61 as an example, the body of the encoder 71 or rotary transformer is mounted on the housing of the first motor 61, and the shaft of the encoder 71 or rotary transformer is connected to the shaft of the first motor 61 or via a gear set. The encoder 71 or rotary transformer can also be used to calculate the rotational speed of the first motor 61, thereby calculating the moving distance of the push plate 30. For a schematic diagram of the encoder 71 installation, refer to Embodiment 4, where the synchronous gear 31 is considered as the motor shaft.

[0045] Example 4 like Figure 7-10 As shown, the difference between this embodiment and Embodiment 1 is that the first unloading drive assembly includes a fourth cylinder 43, and the transverse drive assembly includes a fifth cylinder 52 and a transverse frame 53. The transverse frame 53 is slidably connected to the frame 10, the seat of the fifth cylinder 52 is connected to the frame 10, and the push rod of the fifth cylinder 52 is connected to the transverse frame 53. The placement frame 11 is rotatably connected to the transverse frame 53, the seat of the fourth cylinder 43 is rotatably connected to the transverse frame 53, and the push rod of the fourth cylinder 43 is rotatably connected to one side of the placement frame 11.

[0046] In addition, the first drive mechanism has also been adjusted. Specifically, in this embodiment, the first drive mechanism includes at least one first cylinder 6a, which are connected in series. That is, the push rod of the previous first cylinder 6a is connected to the seat of the next first cylinder 6a. The first cylinder 6a at the beginning is connected to the frame 10, and the first cylinder 6a at the end is connected to the push plate 30. The push plate 30 can be slidably connected to the frame 10 to ensure the stability of the movement direction of the push plate 30. This embodiment is illustrated with a first cylinder 6a with a relatively long stroke.

[0047] Furthermore, a synchronous gear 31 is rotatably connected to the extension frame 33 of the push plate 30, and a second rack 32 meshing with the synchronous gear 31 is provided on the frame 10. In this embodiment, the ranging element is an encoder 71 or a rotary transformer, and the ranging element is connected to the synchronous gear 31. The distance that the push plate 30 moves corresponding to one revolution of the synchronous gear 31 is fixed. The number of revolutions of the synchronous gear 31 can be determined by the encoder 71 and the rotary transformer, thereby calculating the moving distance of the push plate 30.

[0048] Of course, the first unloading drive assembly and the lateral movement drive assembly in this embodiment can also follow the style of Embodiment 1. Furthermore, the detection element 81 can be omitted in this embodiment, the force of the cylinder is relatively small, and it is less likely to damage the stop plate 20 when pushing the bamboo tube 100. In addition, the device in this embodiment can control the duration of pushing and aligning the bamboo tube 100. For example, 2 seconds after the first cylinder 6a starts, it is considered that the push plate 30 and the stop plate 20 have clamped the bamboo tube 100, and then the distance moved by the push plate 30 at this moment is recorded.

[0049] In this embodiment, the structure of the placement rack 11 has also been adjusted. It consists of a support rod 16 and several support plates 17 fixed thereon, with grooves on the support plates 17. Figure 7-9 The image shows only the support plates 17 at both ends of the support rod 16.

[0050] Example 5 Compared with the above embodiments, this embodiment mainly adjusts the ranging element. Specifically, as an alternative, a grating ruler 72 is selected as the ranging element. The ruler body of the grating ruler 72 is connected to the frame 10, and the reading head of the grating ruler 72 is connected to the push plate 30. Figure 11 As shown. The ranging element is a grating ruler 72, which can measure the moving distance of the push plate 30 to calculate the length of the bamboo tube 100. Therefore, a shorter grating ruler 72 can be selected. Another method is to align the zero mark of the grating ruler 72 with the stop plate 20, so that the reading of the grating ruler 72 is the length of the bamboo tube 100.

[0051] As an alternative, a laser rangefinder 73 or an infrared rangefinder can be used as the ranging element. The laser rangefinder 73 or infrared rangefinder is connected to the push plate 30, and the change in the reading of the laser rangefinder 73 or infrared rangefinder during the movement of the push plate 30 represents the distance the push plate 30 has moved. Alternatively, the laser rangefinder 73 or infrared rangefinder can be connected to the stop plate 20. When the push plate 30 is stationary, the distance from the measuring light beam to the push plate 30 can be used to directly obtain the length of the bamboo tube 100. Figure 12 The diagram shows a schematic of a laser rangefinder 73 mounted on a push plate 30.

[0052] As an alternative solution three, the ranging element is a ranging wheel 74, which is connected to the push plate 30 and abuts against the frame 10, such as... Figure 13 As shown. The distance traveled by the measuring wheel 74 is the distance that the push plate 30 moves.

[0053] As an alternative, the ranging element is an industrial camera, with the camera mount 10 positioned high above the frame 10. The distance traveled by the push plate 30 can be obtained by comparing its position when it is stationary. Clear markings can be placed on the push plate 30 to facilitate visual inspection and comparison.

[0054] Example 6 Compared with the above embodiments, this embodiment mainly adjusts the unloading mechanism. Specifically, as an alternative solution, The unloading mechanism includes a second unloading drive assembly 44 and at least one pusher 45 for pushing the bamboo tube 100 out of the placement rack 11. The pusher 45 is placed in the placement rack 11, or the pusher 45 is placed outside the placement rack 11, but the pusher 45 can extend into the placement rack 11. The placement rack 11 is provided with a clearance opening to avoid the pusher 45. The second unloading drive assembly 44 drives the pusher 45 to move. The second unloading drive assembly 44 can be a cylinder. See the simplified structural diagram of the alternative solution. Figure 14 .

[0055] As an alternative, the unloading mechanism is a robotic arm. This robotic arm is positioned above the placement frame 11 and can move the platform along two axes, along with several grippers.

[0056] Example 7 Based on the above embodiments, this embodiment removes the transverse drive assembly, the bamboo tube diameter measuring mechanism 82, the stop plate moving assembly 83, and the bamboo tube centering mechanism 84. Thus, the measuring device in this embodiment is only used to measure the length of the bamboo tube 100.

[0057] Example 8 This embodiment discloses a bamboo splitting machine, which employs the bamboo tube measuring device described in any of the above embodiments. The bamboo splitting machine typically includes a controller 94 connected to the bamboo tube measuring device. The bamboo splitting machine generally also includes a feeding device 91 for feeding the bamboo tube 100 onto the bamboo tube measuring device, a blade disc device 92 for selecting blades, and a pushing device 93 for pushing the bamboo tube 100 toward the blade disc device 92, etc. Figure 15 As shown.

[0058] By controlling the operation of the bamboo tube measuring device through the controller 94, the operation of other devices of the bamboo splitting machine can be better coordinated. In addition, the bamboo tube measuring device can provide feedback on the length of the bamboo tube 100, providing data support for subsequent bamboo tube 100 splitting and other operations (for bamboo tubes 100 of different lengths, the pushing device 93 pushes the bamboo tube 100 to move a different distance for splitting), ensuring that the bamboo tube 100 splitting can be completed smoothly, thereby ensuring that the bamboo splitting machine can adapt to the splitting and processing of bamboo tubes 100 of different lengths.

[0059] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
