Technical Field

[0001] This invention relates to the field of bamboo product processing equipment technology, specifically to an automatic bamboo splitting machine blade magazine and blade changing device. Background Technology

[0002] Bamboo, as a green, environmentally friendly, and renewable biomass material, is increasingly widely used in construction, home furnishings, and handicrafts. As the core equipment for bamboo splitting, the bamboo splitting machine's operating efficiency and processing stability directly determine the initial processing capacity and raw material utilization rate. Currently, most automatic bamboo splitting machines require manual blade changing. Automatic blade-changing bamboo splitting machines primarily use a rotary blade magazine. This type of magazine mounts multiple blades around a rotating disc, driven by a motor, rotating the disc to position the required blades on the working spindle. Its significant drawback is that the blade capacity is strictly limited by the disc size, typically carrying only 4 to 12 blades, and the magazine is difficult to expand, making it unsuitable for continuous processing over extended periods. Furthermore, after prolonged exposure to the high impact and vibration of bamboo splitting operations, the disc's rotation center and positioning accuracy may deviate, affecting the straightness of the split and the quality of the cut.

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] Example 1 In this embodiment, see Figure 1-5 The present invention provides an automatic bamboo splitting machine blade magazine and blade changing device, comprising: a blade magazine moving assembly, a blade changing assembly, and a detection and control assembly; The tool magazine moving assembly includes: a guide rail 1, a tool magazine 4 slidably disposed on the guide rail 1, and a first drive unit 2 fixedly connected to the guide rail 1 and whose output end is connected to the tool magazine 4; the first drive unit 2 is used to pull the tool magazine 4 to move on the guide rail 1. The tool changing assembly includes: a second drive unit 3 fixedly mounted on the guide rail 1, several tool changing parts 5 spaced apart on the tool magazine 4, a bamboo splitting knife holder 6 fixedly mounted on the external bamboo splitting machine 11, and a tool fixing part 7 mounted on the bamboo splitting knife holder 6; the detection and control assembly is used to control the tool magazine moving assembly and the tool changing assembly.

[0016] Preferably, the first drive unit 2 adopts a stepper motor linear actuator, which is electrically connected to a host computer. Under the control of the host computer, the stepper motor linear actuator can accurately control the extension distance of its moving end, thereby accurately controlling the relative position of the tool magazine 4 and the guide rail 1.

[0017] In the above configuration, under the action of external force, the first drive unit 2 moves the position of the tool magazine 4, thereby making the tool changing part 5 face the second drive unit 3. The second drive unit 3 extends under the action of external force, thereby driving the tool changing part 5 to move onto the bamboo splitting knife holder 6. The tool fixing part 7 fixes the tool changing part 5 onto the bamboo splitting knife holder 6 under the action of external force.

[0018] Furthermore, the tool magazine 4 is provided with an array of rectangular slots 401 that extend from front to back; the direction of the rectangular slots 401 is the same as the direction of movement of the output end of the second drive unit 3.

[0019] Preferably, the second drive unit 3 is a linear cylinder, and the piston rod of the second drive unit 3 can be pushed into the rectangular slot 401.

[0020] Furthermore, the blade changing unit 5 includes: a first slider 501 slidably disposed inside the rectangular slot 401, a second slider 502 slidably disposed on the first slider 501, a spring 503 with one end fixedly connected to the blade magazine 4 and the other end fixedly connected to the rear side of the first slider 501, a support arm 504 rotatably connected to the blade magazine 4, and a bamboo splitting blade 505 fixedly connected to the support arm 504; the support arm 504 is also provided with an extension arm for rotatably connecting the second slider 502.

[0021] Preferably, the support arm 504 and the tool magazine 4 are hinged together using a long pin, and the extension arm of the support arm 504 and the second slider 502 are hinged together using a short pin; the support arm 504 and the bamboo splitting knife 505 are fixedly connected by bolts.

[0022] In the above configuration, the first slider 501 is pushed outward under the action of external force, which in turn causes the second slider 502 to move downward along the vertical direction of the first slider 501, which in turn causes the support arm 504 to rotate around the connection point between the support arm 504 and the knife magazine 4, which in turn causes the bamboo splitting knife 505 to be lifted upward. When no external force is applied, the spring 503 pulls the first slider 501 inward under the action of elastic force, which in turn drives the second slider 502 to move up vertically along the first slider 501, which in turn drives the support arm 504 to rotate around the connection point between the support arm 504 and the knife magazine 4, which in turn drives the bamboo splitting knife 505 to retract downward.

[0023] Furthermore, the bamboo-splitting knife holder 6 has a circular bamboo-splitting hole 601 in the middle.

[0024] Furthermore, the tool fixing part 7 includes: an upper chuck flap 701 fixedly disposed on the upper side of the bamboo splitting hole 601, a chuck sensor 702 fixedly disposed on the upper chuck flap 701, a lower chuck flap 703 rotatably disposed on the lower side of the bamboo splitting hole 601, and a third drive unit 704 whose fixed end is rotatably connected to the bamboo splitting tool holder 6; the lower chuck flap 703 is provided with an extension arm for rotatably connecting to the output end of the third drive unit 704.

[0025] Preferably, the lower chuck flap 703 is hinged to the splitting blade holder 6 via a short pin; the third drive unit 704 is a linear cylinder, the piston rod of the third drive unit 704 is hinged to the extension arm of the lower chuck flap 703 via a short pin, and the tail end of the third drive unit 704 is hinged to the splitting blade holder 6 via a short pin.

[0026] Furthermore, the upper chuck flap 701 and the lower chuck flap 703 are provided with grooves inside their arcs for inserting the bamboo splitting knife 505.

[0027] In the above configuration, when the bamboo splitting knife 505 is engaged with the upper chuck 701 under external force, the chuck sensor 702 is triggered, which in turn causes the third drive unit 704 to extend under external force, thereby driving the lower chuck 703 to rotate, so that the lower chuck 703 engages with the bamboo splitting knife 505, thereby fixing the bamboo splitting knife 505; under external force, the third drive unit 704 is shortened, which in turn drives the lower chuck 703 to rotate, so that the lower chuck 703 disengages from the bamboo splitting knife 505, thereby unlocking the bamboo splitting knife 505.

[0028] Furthermore, the detection and control components include: a control panel 8 serving as a host computer and interactive device; a bamboo measuring device 9 located at the front end of the bamboo splitting knife holder 6; and a bamboo splitting knife monitoring device 10 located at the upper end of the bamboo splitting knife holder 6. The bamboo measuring device 9 is used to measure the bamboo material to be processed, and the bamboo splitting knife monitoring device 10 is used to monitor the real-time change of the bamboo splitting knife 505. The control panel 8 is electrically connected to the bamboo measuring device 9, the bamboo splitting knife monitoring device 10, the first drive unit 2, the second drive unit 3, the third drive unit 704, and the chuck sensor 702.

[0029] Example 2 This embodiment provides a working process for a device when there are specific requirements for the width of the bamboo strips during the bamboo splitting process: If the bamboo splitting knife 505 is not yet loaded in the knife magazine 4, first load bamboo splitting knives 505 of different sizes and models onto each support arm 504 of the knife magazine 4 in sequence, and enter the corresponding bamboo splitting knife 505 model number on the control panel 8 according to the assembly position number; if the knife is already loaded, skip this step; then set the required bamboo strip width on the control panel 8 and start the bamboo splitting process: after pressing the start button, put the bamboo into the automatic bamboo splitting machine 11, the bamboo measuring device 9 measures the diameter of the bamboo and feeds it back to the host computer, the host computer calculates the number of slices based on the set width and diameter and selects the most suitable bamboo splitting knife 505; the first drive unit 2 drives the knife magazine 4 to move along the guide rail 1, so that the rectangular slot 401 corresponding to the required bamboo splitting knife 505 is aligned with the second drive unit 2. 3. After the bamboo splitting knife monitoring device 10 confirms that the position is correct, the second drive unit 3 pushes the first slider 501 under the control of the host computer, which in turn drives the second slider 502 to move down along the vertical direction of the first slider 501, which in turn drives the support arm 504 to rotate around the connection position between the support arm 504 and the knife magazine 4, which in turn drives the bamboo splitting knife 505 to lift up, so that the target bamboo splitting knife 505 moves to the bamboo splitting hole 601 of the bamboo splitting knife holder 6. The bamboo splitting knife 505 is embedded in the upper petal 701 of the chuck. After triggering the chuck sensor 702, the third drive unit 704 closes the lower petal 703 of the chuck to fix the bamboo splitting knife 505. Then the second drive unit 3 retracts, and then the external bamboo splitting machine 11 is started to complete the bamboo splitting. After the next bamboo is placed in, its diameter is measured again. The system recalculates and selects a blade. If the new blade is the same as the current one, the bamboo is split directly. Otherwise, the chuck opens, and the spring 503 pulls the first slider 501 to reset the blade. The bamboo splitting blade monitoring device 10 confirms that the reset is complete. The device repeats all the above processes in a loop until all bamboo is processed.

[0030] Example 3 In this embodiment, a working process for a device is provided when a specific type of bamboo-splitting knife needs to be selected during the bamboo-splitting process: If the bamboo splitting knife 505 is not yet loaded in the knife magazine 4 when loading the knife, first load the bamboo splitting knife 505 of different sizes and models onto each support arm 504 of the knife magazine 4 in sequence, and enter the model of the corresponding bamboo splitting knife 505 on the control panel 8 according to the assembly position number; if the knife has already been loaded, skip this step. The next step is the selection process: The target bamboo splitting knife is selected on the control panel 8. The bamboo splitting knife monitoring device 10 first checks whether a bamboo splitting knife 505 is already installed on the bamboo splitting knife holder 6. If not, the first drive unit 2 directly drives the knife magazine 4 to move along the guide rail 1, so that the rectangular slot 401 corresponding to the required bamboo splitting knife 505 is aligned with the second drive unit 3. After the bamboo splitting knife monitoring device 10 confirms the position is correct, the second drive unit 3, under the control of the host computer, pushes the first slider 501, thereby driving the second slider 5... 02 moves downward along the vertical direction of the first slider 501, thereby driving the support arm 504 to rotate around the connection point between the support arm 504 and the knife magazine 4, thereby driving the bamboo splitting knife 505 to rise upward, so that the target bamboo splitting knife 505 moves to the bamboo splitting hole 601 of the bamboo splitting knife holder 6, the bamboo splitting knife 505 is embedded in the upper petal 701 of the chuck, after triggering the chuck sensor 702, the third drive unit 704 closes the lower petal 703 of the chuck to fix the bamboo splitting knife 505, and then the second drive unit 3 retracts; If a knife is already installed on the bamboo knife holder, the system will determine whether its model matches. If it matches, it will prompt "Bamboo splitting knife is equipped". If it does not match, the third drive unit 704 will open the chuck first. After the bamboo splitting knife monitoring device 10 confirms that the original bamboo splitting knife 505 has been reset, the above-mentioned knife magazine 4 movement and knife changing action will be performed. After the knife selection is completed, the external bamboo splitting machine 11 can be started to complete the bamboo splitting.

[0031] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
