AI Technical Summary
[0002]目前有一种草药钩藤,需要精准的对有钩的位置进行切断分离,因为只有有钩的位置才有药用价值,其他位置药用价值不大,目前钩藤剪断分离加工的多为人工手持剪刀剪断分离,但人工对钩藤加工剪断有缺点,钩藤剪多了手臂容易酸痛,目前也有机器进行剪断分离的,现有的机器加工效率慢,主要由以下缺陷造成,缺陷1、机器所带动的刀片不是持续运动切断的,而是每切断一个钩,刀片就要停到起点位置,等待下一刀的触发信号,这个等待信号的一个流程下来,每切一刀就会多出一个几百毫秒甚至更多等待切割的时间,缺陷2、现有的钩藤剪断机都是把要剪断的位置先传送到刀片下面后,然后再启动刀片进行切断,刀片大多是由电机提供动力的,于是每剪一个钩都多了电机停止和启动的时间,导致电机启动和停止所占用的时间比正真剪钩藤的时间还多,从而达不到高速剪断的目的,电机平凡启停需要有足够很大的功率还有时间才能摆脱自身旋转时所产生的惯性力和刀具运动所产生的惯性力,目前大部分电机启动时间在200-400毫秒之间(比如说步进电机),加上电机运动到停止也需要200-400毫秒之间,启动和停止时间加起来总共耗时400-800毫秒,再加上电机等待启动信号的时间(200毫秒),平均每剪断一个勾差不多就用去了600-1000毫秒,这样换算下来也1个小时也就能剪断3000-4000个钩,钩藤差不多5000-10000个钩1公斤,机器1个小时也就只能剪断1斤左右的钩藤,其速度只和人工相当,缺陷3,现有的机器为了缩短刀具启动信号的等待时间,直接把感应器安装在刀具上,这样安装的缺点就是在切割钩藤时所产生的碎屑就会溅到感应器上,导致感应失灵,机器停止运行,如果是切断带有水分的生钩藤,直接把感应放在刀具上的这个方案是不可行的,因为生钩藤水分更多,更容易溅到感应器,缺陷4,因为现有机器剪断速度慢,无法实现工人流水线式的加工方式,流水线式加工就是工人只需把钩藤放在流水线的传输带上即可,机器自动加工,总结下来就是目前所发明钩藤剪断机器不尽人意
1、通过高速旋转的刀片对钩藤进行持续剪断,大大的提高个钩藤的剪钩速度。

Abstract
Description
Technical Field
[0001] This invention relates to the field of Uncaria processing technology, specifically to a Uncaria cutting device. Background Technology
[0002] Currently, there is a medicinal herb called Uncaria rhynchophylla that requires precise cutting and separation of the hooked parts, as only the hooked parts have medicinal value; other parts have little medicinal value. Currently, the cutting and separation of Uncaria rhynchophylla is mostly done manually with hand-held scissors. However, manual cutting has drawbacks; cutting too much can easily cause arm soreness. Machines are now available for cutting and separation, but existing machines are slow, mainly due to the following defects: Defect 1: The blades driven by the machine do not cut continuously. Instead, after cutting each hook, the blades stop at the starting position, waiting for the trigger signal for the next cut. This waiting process takes a long time... Each cut adds hundreds of milliseconds or even more of waiting time for the cutting. Defect 2: Existing hook vine cutting machines first transmit the area to be cut to the blade before starting the blade to cut. Since the blade is mostly powered by a motor, each cut adds to the motor's start-stop time, making the start-stop time longer than the actual cutting time. This prevents high-speed cutting. Frequent motor starts and stops require significant power and time to overcome the inertial forces generated by its own rotation and the blade's movement. Currently, most motors have a start-up time of 200- The start-up and stop times are between 400 and 800 milliseconds (for example, with a stepper motor). Adding the 200-400 milliseconds required for the motor to stop, the total start-up and stop time is 400-800 milliseconds. Adding the 200 milliseconds of waiting for the start signal, the average time to cut one hook is approximately 600-1000 milliseconds. This translates to only being able to cut 3000-4000 hooks per hour. Since 5000-10000 hooks weigh about 1 kg of vine, the machine can only cut about 1 catties of vine per hour, making its speed comparable to manual labor. Defect 3: Existing machines, in order to shorten the blade start-up time... The waiting time for the motion signal is limited. Installing the sensor directly on the blade has the drawback that debris generated during cutting the hook vine will splash onto the sensor, causing it to malfunction and the machine to stop. This solution is not feasible when cutting raw hook vine with moisture, as the higher moisture content makes it easier for the sensor to be splashed. Another drawback is the slow cutting speed of existing machines, which prevents automated assembly line processing. An assembly line process involves workers simply placing the hook vine on a conveyor belt for automatic processing. In summary, the currently invented hook vine cutting machine is unsatisfactory. Summary of the Invention
[0003] The purpose of this invention is to address the aforementioned shortcomings of existing hook vine cutting machines by proposing a hook vine cutting device.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A hook vine cutting device includes a continuously moving blade, an optical fiber sensor, and a conveying structure. The device is characterized in that an optical fiber sensor is installed in front of the continuously moving blade, and the operation of the conveying structure is controlled by the optical fiber sensor.
[0006] Furthermore, the aforementioned hook vine cutting device is characterized in that the continuously moving blade is powered by a motor, and the blade does not start and stop intermittently during operation.
[0007] Furthermore, the aforementioned hook vine cutting device is characterized in that the conveying structure is a rolling conveyor.
[0008] The beneficial effects of this invention are: 1. The high-speed rotating blade continuously cuts the hook vines, greatly increasing the cutting speed of each hook vine.
[0009] 2. The sensor is installed in front of the blade, making the machine more durable, reducing maintenance costs, and saving the time required for machine repair, thus enabling high-intensity continuous processing.
[0010] 3. By simplifying complex machines, the manufacturing cost of the machines is greatly reduced, making them easier to promote and use.
[0011] 4. Its cutting speed is many times faster than existing machines, enabling assembly line-style processing and improving production efficiency. Attached Figure Description Figure 1 This is a perspective view of a hook vine cutting device proposed in this invention.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0016] Reference Figure 1-3The support frame 1 is equipped with a blade drive motor 2, a conveyor structure drive motor 3, a feed inlet 5, a conveyor structure 4, a discharge outlet 9, a continuously moving blade 10, and a fiber optic sensor 8. During operation, the blade drive motor 2 and the conveyor structure drive motor 3 rotate. The rotation of the conveyor structure drive motor 3 drives the conveyor structure 4 (roller) to rotate via the belt 7. The blade drive motor 2 then drives the continuously moving blade 10 to rotate counter-clockwise via its motor shaft. The blade drive motor 2 rotates at a fixed speed. The hook vine is fed into the feed inlet 5 manually or via an assembly line. The conveyor structure 4 (roller) and the fiber optic sensor 8 are located between the feed inlet 5 and the discharge outlet 9. When the hook vine encounters the rotating conveyor structure 4 (roller), it continues to be conveyed forward. The vine consists of a pole and a hook. The pole is generally less than 5 mm in diameter, while the hook is greater than 5 mm. When the hook is conveyed to the position of the fiber optic sensor 8, it will be identified by the fiber optic sensor 8 (a matrix fiber optic sensor specifically designed to identify the size of objects and control the on / off time of the circuit). At this time, the fiber optic sensor 8 will control the conveyor drive motor 3 to decelerate, accelerate, or even stop. Simultaneously, the conveyor structure 4, connected to the conveyor drive motor 3 via the belt 7, will also accelerate or decelerate. Under the control of the fiber optic sensor 8, the conveyor structure 4 conveys the hook vine to the position to be cut within a specified time between the continuously moving blade 10 and the feed inlet 9 for cutting and segmentation. (The cutting time of the continuously moving blade 10, for example, its rotation speed per second...) 20 revolutions are equivalent to the continuous motion blade 10 passing through the discharge port 9 40 times. This means the continuous motion blade 10 passes through the discharge port 9 once every 25 milliseconds. In other words, as long as the section of the hook vine that needs to be cut is conveyed to the continuous motion blade 10 within 20 milliseconds (the length of hook vine that needs to be cut is generally 28 mm, and conveying 28 mm in 20 milliseconds is not fast for the conveyor structure 4), the cutting position of the hook vine needs to be placed under the continuous motion blade 10. Since the blade drive motor 2 rotates at a fixed speed, the rotation speed of the continuous motion blade 10 is also fixed. Once the rotation speed of the continuous motion blade 10 is fixed, the fiber optic sensor 8 adjusts the rotation speed of the conveyor structure drive motor 3 by calculating the time difference, thus placing the section of the hook vine that needs to be cut under the continuous motion blade 10 in advance for cutting. The continuously moving blade 10 rotates at a fixed speed. The length of the hook that needs to be cut is determined by the conveying speed of the conveying structure 4. When the first hook is cut, the second, third, and subsequent cuts are performed in a cyclical manner. As for how the fiber optic sensor 8 knows when the continuously moving blade 10 passes the discharge port 9, many motors now have built-in position recognition functions, such as encoders, pulse-based encoders, absolute encoders, or external sensors. These can sense the position of the continuously moving blade 10 and the time it arrives at the discharge port 9. Knowing when the continuously moving blade 10 arrives at the discharge port, the conveying structure 4 simply needs to stagger the timing and deliver the hook to the position to be cut under the continuously moving blade 10.The specific location to which the Uncaria rhynchophylla is delivered is adjusted during the setup process using fiber optic sensor 8; the setup process will not be detailed here.
[0017] In general, existing hook-cutting machines first convey the area to be cut to the blade before starting the blade to cut. The blade is mostly powered by a motor, so each hook cut involves additional time for the motor to stop and start, resulting in the start-up and stop time being longer than the actual cutting time, thus failing to achieve high-speed cutting. The technical solution of this invention mainly uses a continuously cutting blade, which can be a continuously linear or piston-moving blade. The hook is conveyed through a conveyor structure 4 to the position of a fiber optic sensor 8. The fiber optic sensor 8 triggers the sensor to determine the position of the hook. Then, the speed of the drive motor 3 and the conveying structure 4 is controlled. The conveying structure 4 is controlled to convey the position to be cut under the continuous motion blade 10 within a specified time. Since the continuous motion blade 10 is constantly rotating, when the position to be cut is conveyed under the continuous motion blade 10, the continuous motion blade will immediately cut the hook vine. The conveying structure 4 continuously feeds the material, and the fiber optic sensor 8 continuously senses and controls the feeding position of the conveying structure 4. The continuous motion blade 10 continuously rotates at high speed, and the hook vine is continuously cut at high speed, thereby achieving the purpose of cutting the hook vine at high speed.
[0018] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope of the technology disclosed in the present invention should be covered within the scope of protection of the present invention.
