In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
[0023] As attached Figure 1-6As shown, the present invention provides a bamboo tube cutting and sorting machine, including a sawing table 10, a sorting table 20 and a length detection module 30 for detecting the length of the bamboo tube, the sorting table 20 is connected to the sawing table 10, the length detection module 30 is arranged on the sawing table 10, the sorting table 20 includes a conveying mechanism, sorting mechanisms arranged in sequence on both sides of the conveying direction of the conveying mechanism, the length detection module 30 includes a plurality of groups of measuring mechanisms arranged in sequence, the measuring mechanism includes a mounting base 31, a travel switch 32 arranged on the mounting base 31, and a trigger plate 34 for triggering the travel switch 32 and the mounting base. The plate 31 is movably connected, and multiple groups of mounting base plates 31 are arranged in a stepped trigger plate 34 near the side of the conveying mechanism. The trigger plate 34 is arranged on the side of the travel switch 32 facing the saw table 10. The front end of the trigger plate 34 is flush with the end of the mounting plate near the conveying mechanism, and the end of the trigger plate 34 away from the travel switch 32 is hinged to the mounting base plate 31. The travel switch 32 is electrically connected to the controller of the saw table 10; the sorting mechanism includes a sorting gate 23 and a gate cylinder 25 for driving the sorting gate 23 to rotate toward one side of the conveying mechanism. The sorting gate 23 is rotatably arranged on both sides of the conveying mechanism, and the sorting gate When the door 23 is in the closed state, a conveying guide groove 27 is formed along both sides of the conveying mechanism. The gate cylinder 25 is arranged on both sides of the conveying mechanism through the mounting stand 26, and the front end of the piston rod of the gate cylinder 25 is hinged to the sorting gate 23; the conveying mechanism includes a frame 21, a conveyor belt 22 arranged on the frame 21, and the roller of the conveyor belt 22 is rotatably arranged on the frame 21 through a universal bearing; the saw table 10 includes a stand 11, a swing bracket 12 arranged on the stand 11, and a cutting device arranged on the swing bracket 12. The stand 11 is provided with a bracket shaft 13, and the swing bracket 1 The bracket shaft 13 is rotatably connected via a universal bearing. The cutting device includes a saw blade 14, a saw shaft 15, and a drive motor 16 for driving the saw blade 14. The saw shaft 15 is mounted on the swing bracket 12 via a universal bearing. The saw blade 14 is fixedly mounted on the saw shaft 15. The drive motor 16 is connected to the saw shaft 15 via a transmission belt. A cut-off sensor is provided on the stand 11 relative to the saw blade 14. The drive motor 16, the travel switch 32, and the cut-off sensor are electrically connected to a control box 40 of the saw table 10, respectively. A PLC controller for controlling the operation of the entire machine is provided in the control box 40.
[0024] Specifically, the cutting position of the saw blade 14 of the saw table 10 is defined as the zero point, and each set of trigger plates 34 defines the corresponding length. In the bamboo tube cutting process, some of the bamboo tube lengths need to be determined according to the diameter thickness of the bamboo tube. For example, if the diameter thickness is 2mm, the length of the bamboo tube should be cut to 1000mm. When the diameter thickness is 3mm, the length of the bamboo tube should be cut to 800mm. There are also some processes that require removing the bamboo nodes and cutting out the hollow bamboo tube as long as possible according to the specifications, such as 320mm, 370mm, 420mm, 470mm, 1000mm and other sizes. For example, if the distance between two bamboo nodes is 460mm, after removing the bamboo nodes, The bamboo tube is cut into 420mm. When the distance between two bamboo nodes is 350mm, the bamboo tube is cut into 320mm after removing the bamboo nodes. When cutting the bamboo tube, the worker selects the corresponding measuring mechanism according to the thickness, outer diameter or bamboo node of the bamboo, presses the front end of the bamboo against the trigger plate 34, and triggers the travel switch 32 through the trigger plate 34 to measure the length from the front end of the bamboo to the cutting position, thereby determining the specifications of the cut bamboo tube and realizing rapid measurement of the length of the bamboo tube. Since the bamboo may trigger multiple sets of trigger plates 34 when it is placed, a cutting sensor is set at a position opposite to the saw blade 14 on the stand 11. When the swing bracket 12 is pressed down to drive the saw blade 14 to cut the bamboo, the worker can cut the bamboo tube by the trigger plate 34. , triggering the cutting sensor, the PLC controller judges and reads the correct signal of the travel switch 32 through the feedback signal of the cutting sensor, and determines the length of the bamboo tube; wherein, the mounting base 31 is arranged in a stepped shape near the side of the conveying mechanism. When placing the bamboo, the front end of the bamboo can be quickly aligned with the step for positioning, which makes the operation more convenient; when the saw blade 14 cuts the bamboo and the bamboo tube falls onto the conveyor belt 22 under the action of gravity, the conveyor belt 22 is transported forward by the motor. When the bamboo tube is delivered to the corresponding position, the PLC controller controls the corresponding gate cylinder 25 to move and drive the sorting gate 23 to rotate to the inside of the conveyor belt 22 and open according to the detection result of the length detection module 30. Guided by the sorting gate 23 and pushed by the conveyor belt 22, the bamboo tube falls into the designated classification area. After the bamboo tube falls into the classification area, the gate cylinder 25 drives the sorting gate 23 to close in the opposite direction, thereby completing a sorting action. The sorting action and the cutting action can be performed in sequence. The subsequent sorting order is determined according to the trigger data recorded for each cutting. It should be noted that the conveying position of the bamboo tube on the conveyor belt 22 can be determined by a sensor provided on the conveyor belt 22, or roughly determined by measuring the conveying speed of the conveyor belt 22. Compared with the existing sorting method, the above-mentioned sorting method greatly improves the sorting efficiency and accuracy, and can also effectively reduce labor costs.
[0025] Furthermore, the limit switch 32 is a direct-acting limit switch 32, the mounting base 31 is L-shaped, one side of the mounting base 31 is fixed on the sorting table 20, and the other side of the mounting base 31 faces the saw table 10. A sliding hole is provided on the mounting base 31, and the push rod 33 of the limit switch 32 is slidably connected to the sliding hole, and the push rod 33 protrudes from the side of the mounting base 31 facing the saw table 10. When the trigger plate 34 is triggered by the pressure of the bamboo, the trigger plate 34 rotates toward the side of the push rod 33, pushing the push rod 33 to trigger the limit switch 32.
[0026] Furthermore, the sorting gate 23 is hinged to the mounting stand 26 of the adjacent sorting mechanism. A guide ramp 24 is provided at one end of the sorting gate 23 near the hinge point. The guide ramp 24 is located on the side of the sorting gate 23 away from the conveying mechanism. The guide ramp 24 guides the bamboo tubes to fall into the corresponding classification area to prevent the bamboo tubes from deviating due to inertia.
[0027] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
