Description

Technical Field

[0001] This utility model relates to the field of bamboo and wood processing machinery technology, specifically a bamboo strip cutting machine for fixed lengths. Background Technology

[0002] A bamboo strip cutting machine is a mechanical device specifically used for cutting bamboo strips. During the production process, it is necessary to cut longer bamboo strips. Since the length of bamboo strips needs to be kept as consistent as possible, a bamboo strip cutting machine is needed to cut longer bamboo strips evenly to meet the standard length requirements.

[0003] The prior art, disclosed in CN215902833U, provides a steel bar length-fixing follow-up cutting device, including a support platform, a mounting base, a pair of limiting pressure rollers, and a cutting component. The support platform is a rectangular platform, the mounting base is installed at one end of the support platform, the pair of limiting pressure rollers are installed on one side of the mounting base, and the cutting component is installed on the other side of the mounting base. A follow-up traction mechanism is provided on the support platform. This utility model relates to the field of steel bar processing technology. This steel bar length-fixing follow-up cutting device uses a follow-up traction mechanism for follow-up traction and length fixing. The length of the steel bar can be accurately determined by laser ranging. After length positioning, the steel bar is cut by the cutting component. The length fixing is accurate and the response is fast. The structure is simple, which can effectively reduce the maintenance cost of the equipment, facilitate deployment, and is easy to use.

[0004] In the aforementioned patent, the main method involves sliding the sliding seat and moving the strip to be tested along with it. Finally, laser ranging is used to determine the tangent of the strip to be tested. However, this method of strip length determination requires a limiting structure to limit the strip to be tested. This causes significant friction between the strip to be tested and the limiting structure during the movement of the strip, resulting in severe wear on the outer wall of the strip to be tested. This reduces the integrity of the strip to be tested cut off by the cutting device. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a bamboo strip cutting machine that solves the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bamboo strip cutting machine, comprising a machine body, a positioning frame for positioning bamboo strips and a pressing device for pressing and limiting bamboo strips are fixedly installed on the top of the machine body, and cutting devices are fixedly installed on both sides of the top of the machine body, the cutting devices being symmetrically located on both sides of the positioning frame, a controller for controlling the electronic components inside the cutting machine is fixedly installed on one side of the machine body, the cutting device comprising multiple first support plates fixedly installed on the machine body, a rotatable lead screw fixedly installed in the first support plate on the same side, a length plate being movably installed on the lead screw, a distance sensor for measuring distance is fixedly installed on the first support plate away from the length plate, a connecting column is fixedly installed on the length plate, and a cutting component for cutting bamboo strips is fixedly installed at the end of the connecting column away from the length plate. A cutting component for cutting bamboo strips is fixedly installed at the end of the connecting column away from the fixed-length plate, which allows the bamboo strip cutting machine to quickly cut bamboo strips through the cutting component, thus improving the efficiency of the bamboo strip cutting machine in cutting bamboo strips.

[0007] Furthermore, the cutting assembly includes a second support plate fixedly mounted on the connecting column. A sub-controller is fixedly mounted on the end of the second support plate away from the lead screw, and the sub-controller is remotely connected to the main controller. An inverted electric push rod is fixedly mounted on the second support plate, and the electric push rod is electrically connected to the sub-controller. A cutting blade is fixedly connected to the output end of the electric push rod. The cutting line of the cutting blade is on the same plane as the side of the measuring plate near the distance sensor. The inner wall of the positioning frame that contacts the bamboo strip end is on the same plane as the side of the measuring plate near the distance sensor. Because the inner wall of the positioning frame that contacts the bamboo strip end is on the same plane as the side of the measuring plate near the distance sensor, when the measuring plate moves to the end position, the end point of the bamboo strip and one side of the measuring plate are on the same plane, improving the accuracy of the bamboo strip measuring machine for measuring the bamboo strip.

[0008] Furthermore, the cutting device also includes a first motor fixedly mounted on the machine body. The control box of the first motor is electrically connected to the controller. The output end of the first motor is fixedly connected to the lead screw. Auxiliary shafts are fixedly mounted within multiple support plates away from the lead screw. A length-fixing plate is also movably mounted on the auxiliary shafts. The auxiliary shafts are used to assist in the stable movement of the cutting assembly. The auxiliary shafts assist in the stable movement of the cutting assembly, making the internal structure of the bamboo strip length-fixing machine move more stably and improving the overall operational stability of the bamboo strip length-fixing machine.

[0009] Furthermore, the pressing device includes a second motor and a mounting frame fixedly mounted on the machine body. The control box of the second motor is electrically connected to the controller. A rotating shaft is fixedly connected to the output end of the second motor. A pressing component for limiting the bamboo strip is fixedly mounted at the center of the rotating shaft. The pressing device also includes a locking component fixedly mounted on the machine body, which is used to lock and fix the pressing component. The locking component locks and fixes the pressing component, ensuring that the bamboo strip can be stably positioned on the machine body when being cut in the bamboo strip cutting machine, thus improving the quality of bamboo strip cutting.

[0010] Furthermore, the pressing assembly includes a connecting cylinder fixedly mounted on a rotating shaft. A first arc strip is fixedly connected to the connecting cylinder. A central frame is fixedly connected to the end of the first arc strip away from the connecting cylinder. A second arc strip is fixedly mounted to the end of the central frame away from the first arc strip. A locking strip is fixedly connected to the bottom of the second arc strip. A cylindrical locking groove is formed at the center of the locking strip. The locking strip is used to insert into the mounting frame for fixation. The locking strip's insertion into the mounting frame for fixation makes the internal structure of the bamboo strip cutting machine more robust and reliable, improving the operational safety of the bamboo strip cutting machine.

[0011] Furthermore, a spring column is fixedly installed at the center of the frame, and a pressing arc strip for pressing the bamboo strip is fixedly connected to the lower end of the spring column. This fixed connection of the pressing arc strip to the lower end of the spring column makes the internal structure of the bamboo strip cutting machine more robust and reliable, improving the stability of its operation.

[0012] Furthermore, the locking assembly includes a block fixedly mounted on the body, with an entry groove for the locking strip to enter at the center of the block, and a locking shaft bolted inside the block, the locking shaft penetrating the block and the locking strip. Beneficial effects

[0013] Compared with the prior art, the present invention has the following beneficial effects: This invention allows the bamboo strip to be cut to remain stationary on the positioning frame inside the bamboo strip cutting machine. By moving the cutting component inside the cutting device and measuring the distance between the length plate and the distance sensor, the bamboo strip cutting machine can achieve precise length cutting while preventing the outer surface of the bamboo strip from rubbing against other structures of the machine during cutting, thus improving the integrity of the bamboo strips cut by the bamboo strip cutting machine.

A connecting column 38 is fixedly installed on the length-fixing plate 36. A cutting assembly 31 for cutting bamboo strips is fixedly installed at one end of the ruler plate 36. The cutting assembly 31 includes a second support plate 312 fixedly installed on the connecting column 38.

A cutting blade 313 is fixedly connected to the output end of the electric actuator 314. The cutting line of the cutting blade 313 is on the same plane as the side of the ruler plate 36 near the distance sensor 34. The inner wall of the positioning frame 4 that contacts the end of the bamboo strip is on the same plane as the side of the ruler plate 36 near the distance sensor 34. The device 3 also includes a first motor 37 fixedly mounted on the body 1. The control box of the first motor 37 is electrically connected to the controller 2. The output end of the first motor 37 is fixedly connected to the lead screw 35. An auxiliary shaft 32 is fixedly mounted in one of the multiple first support plates 33 away from the lead screw 35. A length plate 36 is also movably mounted on the auxiliary shaft 32. The auxiliary shaft 32 is used to assist the stable movement of the cutting component 31. The pressing device 5 includes a second motor 51 fixedly mounted on the body 1 and a mounting frame 52. The control box of the second motor 51 is electrically connected to the controller 2. A rotating shaft 53 is fixedly connected to the output end of the second motor 51. A pressing component 54 for limiting the bamboo strip is fixedly mounted at the center of the rotating shaft 53. The pressing device 5 also includes components fixedly mounted on the body 1. The locking assembly 55 is used to lock and fix the pressing assembly 54. The pressing assembly 54 includes a connecting cylinder 542 fixedly installed on the rotating shaft 53. A first arc strip 541 is fixedly connected to the connecting cylinder 542. A middle frame 543 is fixedly connected to the end of the first arc strip 541 away from the connecting cylinder 542. A second arc strip 546 is fixedly installed to the end of the middle frame 543 away from the first arc strip 541. A locking strip 547 is fixedly connected to the bottom of the second arc strip 546. A cylindrical locking groove is opened at the center of the locking strip 547. The locking strip 547 is used to insert into the mounting frame 52 for fixation. A spring post 544 is fixedly installed at the center of the middle frame 543. A pressing arc strip 545 for pressing the bamboo strip is fixedly connected to the lower end of the spring post 544.The locking assembly 55 includes a block 552 fixedly mounted on the body 1. An entry groove 553 for the locking strip 547 to enter is provided at the center of the block 552. A locking shaft 551 is bolted inside the block 552, and the locking shaft 551 penetrates both the block 552 and the locking strip 547.

[0018] The controller 2 has a microcontroller control board and a corresponding Bluetooth module, and the sub-controller 311 also has a microcontroller control board and a corresponding Bluetooth module. The controller 2 and the sub-controller 311 are remotely connected via Bluetooth. The electric push rod 314 is electrically connected to the sub-controller 311. The control boxes of the first motor 37 and the second motor 51 are both electrically connected to the controller 2. Therefore, the controller 2 can directly control the electric push rod 314, the first motor 37 and the second motor 51. The microcontrollers inside the controller 2 and the sub-controller 311 are all common models available on the market, so this utility model will not be described in detail.

[0019] Since the cutting line of the cutting blade 313 is on the same plane as the side of the fixed-length plate 36 near the distance sensor 34, and the inner wall of the positioning frame 4 that contacts the end of the bamboo strip is on the same plane as the side of the fixed-length plate 36 near the distance sensor 34, when the fixed-length plate 36 moves to the first support plate 33 near the first motor 37 and fits, the end of the bamboo strip is horizontal with the fixed-length plate 36. At this time, the distance moved by the fixed-length plate 36 is the length of the bamboo strip. The distance sensor 34 is used to detect the distance between the distance sensor 34 and the fixed-length plate 36. At this time, the initial distance of the distance sensor 34 minus the distance after the fixed-length plate 36 moves is the length of the bamboo strip. The user can cut the bamboo strip of the cutting device 3 to the preset length according to the specific usage situation.

[0020] The bamboo strip to be cut is located inside the middle frame 543, and the pressing arc bar 545 is constantly squeezed downward by the spring column 544. Therefore, the pressing arc bar 545 can constantly squeeze the bamboo strip inside the middle frame 543, making it more stable when it is cut by the cutting device 3, thus improving the practicality of the bamboo strip length cutting machine.

[0021] Since both the block 552 and the locking strip 547 have cylindrical grooves at their centers, when the locking shaft 551 penetrates the grooves in the center of the block 552 and the locking strip 547 and is fixed with bolts, the block 552 and the locking strip 547 can be firmly fixed, thus improving the stability of the bamboo strip cutting machine.

[0022] The working principle of this utility model is explained below: Unless otherwise specified, all internal mechanical structures of the bamboo strip cutting machine are fixed by threads. To allow for a more intuitive observation of the technical features, bolt connections are appropriately concealed in the diagram. When using the bamboo strip cutting machine, the user places all the bamboo strips to be cut into the positioning frame 4, ensuring the ends of the bamboo strips are against the inner wall of the positioning frame 4. The cutting plate 36 moves to the first support plate 33 near the first motor 37. At this point, the user needs to record the value displayed in the distance sensor 34. Then, the user starts the first motor 37 via the controller 2. The running first motor 37 causes the lead screw 35 to rotate, directly moving the cutting plate 36 towards the distance sensor 34. The user then observes the value inside the distance sensor 34. When the initial value of the distance sensor 34 minus the current value of the distance sensor 34 equals the required bamboo strip length, the first motor 37 stops running. Then, the user operates the electric push rod 314 through the controller 2 and the sub-controller 311. The electric push rod 314 then moves downward with the cutting blade 313 to cut the bamboo strip on the machine body 1. Since the bamboo strip is stationary during operation, and the length is determined by the movement of the cutting device, the bamboo strip will not rub against the internal structure of the bamboo strip cutting machine during the cutting process. This ensures that the bamboo strip cutting machine can cut the bamboo strip to a precise length while preventing the outer surface of the bamboo strip from rubbing against other structures of the bamboo strip cutting machine, thus improving the integrity of the bamboo strip cut by the bamboo strip cutting machine.

[0023] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
