[0001] This utility model relates to the field of metal processing technology, specifically to a processing device for a circular blade edge. Background Technology

[0002] In today's booming manufacturing industry, cutting blades, as a key basic component, are widely used in many fields such as machining, medical, and food. Traditional cutting blade processing devices are inefficient and have limited precision, making it difficult to meet the demands of modern industry for high-performance cutting blades.

[0003] For example, Chinese patent (publication number: CN208289554U) discloses a blade processing device that solves the problem of high processing difficulty and has the effect of low processing difficulty. To solve the above problems, this utility model discloses a processing device for a circular blade edge, including a base, a first support rod on the base, a drive motor fixedly mounted on the first support rod, and a grinding wheel fixedly mounted on the rotating shaft of the drive motor for grinding the circular blade; a self-rotating second support rod vertically mounted on the base, a positioning plate on the second support rod, a rotating shaft vertically mounted on the positioning plate, and a clamping member for fixing the circular blade sleeved on the rotating shaft; a ratchet wheel coaxially fixedly mounted on the clamping member, the ratchet wheel and the circular blade having the same number of teeth, and a pawl rotatably connected to the positioning plate to cooperate with the ratchet wheel. With the cooperation of the ratchet wheel and the pawl, the same rotation angle of the circular blade is achieved each time, reducing the processing difficulty.

[0004] However, the processing efficiency of this device is not high enough. It can only grind one side at a time, and after grinding, the blade needs to be flipped over to grind the second side. Therefore, it is not efficient in actual use. Hence, a processing device for round blade edges is proposed to solve the above problems. Summary of the Invention

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please refer to Figures 1 and 2. In this embodiment, a processing device for a circular blade edge includes a base 1. Three support plates 2 are fixed to the top of the base 1. The three support plates 2 serve as isolation and, together with the movable door, form a closed effect, improving the safety of blade processing. A stabilizing plate 3 is fixed to the top of the three support plates 2. The stabilizing plate 3 can further improve safety and provide stable support for the grinding component 5. A positioning component 4 is provided on the top of the base 1 and inside the three support plates 2, extending into the base 1 and facilitating tool positioning to improve tool grinding efficiency. A grinding component 5 is provided on the top of the stabilizing plate 3, penetrating the stabilizing plate 3 and capable of efficiently grinding the circular blade. A movable door is hinged to the front of the support plate 2, and an observation window is embedded in the movable door, allowing the user to observe the blade.

[0023] In addition, the positioning component 4 includes a stabilizing seat 401 fixed to the top of the base 1. The stabilizing seat 401 is fixed to the base 1 by bolts. When the stabilizing seat 401 needs to be replaced, the bolts can be unscrewed. The inner side of the stabilizing seat 401 is provided with a moving hole, and the top of the base 1 is provided with a mounting hole that communicates with the moving hole and is coaxial with the moving hole.

[0024] It should be further explained that the positioning component 4 also includes a telescopic rod 402 fixed to the bottom of the mounting hole. The mounting hole can provide a stable space for the telescopic rod 402. The top of the telescopic rod 402 is rotatably connected to the connecting rod 403 located in the mounting hole through a bearing. When the grinding component 5 moves down, it will generate friction with the moving rod 404. In order to reduce the heat generated by friction, the use of a bearing can effectively improve the rotational flexibility of the moving rod 404. The top of the connecting rod 403 is fixed with the moving rod 404 extending out of the moving hole.

[0025] It is known that the telescopic rod 402 includes a stabilizing rod fixed to the bottom wall of the mounting hole. A stabilizing spring is fixed to the inner bottom wall of the stabilizing rod. The stabilizing spring can accumulate elastic potential energy when the moving rod 404 moves down, and at the same time provide a stable space for the moving rod 404. A displacement rod extending out of the stabilizing rod is fixed to the top of the stabilizing spring. The top of the displacement rod is rotatably connected to the connecting rod 403 through a bearing.

[0026] In this embodiment, the movable rod 404 can achieve a good positioning effect during use, so that it is stably placed in the stable seat 401. Then, by cooperating with the grinding component 5, both sides of the blade can be ground at the same time, which can effectively improve the grinding efficiency.

[0027] Please refer again to Figures 1 to 2 and Figure 3. In order to effectively improve the grinding efficiency, the grinding component 5 in this embodiment includes a stabilizing frame 501 fixed to the top of the stabilizing plate 3. The stabilizing frame 501 has good stability and can provide stable support for the electric push rod 502. An electric push rod 502 extending out of the stabilizing frame 501 is fixed to the inner side of the stabilizing frame 501. A moving plate 504 is fixed to the output end of the electric push rod 502. The stabilizing frame 501 passes through the moving plate 504. A drive motor 505 is fixed below the moving plate 504. The drive motor 505 can provide power to the grinding blade of the disassembly and assembly part 503. The output shaft of the drive motor 505 is provided with a disassembly and assembly part 503 that passes through the stabilizing plate 3.

[0028] In addition, the stabilizing frame 501 includes four support legs fixed to the top of the stabilizing plate 3. Each of the four support legs has a stabilizing sleeve fixed to its outer surface. A support rod is fixed to one side of each of the four stabilizing sleeves. Since the electric push rod 502 is relatively far from the four support rods, four support rods are needed to connect them. An mounting sleeve is fixed to one side of each of the four support rods. The electric push rod 502 is fixed to the stabilizing frame 501 through the mounting sleeve. The moving plate 504 has four displacement holes. The four support legs pass through the moving plate 504 through the four displacement holes. The four support legs passing through the moving plate 504 through the four displacement holes can limit the movement of the moving plate 504. Since the drive motor 505 requires a large rotational force to drive the disassembly and assembly part 503 to rotate, the rotational force will act on the moving plate 504. The electric push rod 502 alone is not stable enough. The four support legs can significantly improve the stability.

[0029] It should be further explained that the disassembly and assembly part 503 includes an active rod 5031 fixed to the output shaft of the drive motor 505. The active rod 5031 extends to the outside of the stabilizing plate 3. A connecting sleeve 5032 extending to the bottom of the active rod 5031 is fixed to the outer surface of the active rod 5031. A driven rod 5033 is fixed to the inner side of the connecting sleeve 5032 and located below the active rod 5031. When the driven rod 5033 needs to be replaced, the driven rod 5033 can be quickly removed by simply removing the bolts of the connecting sleeve 5032. The disassembly and assembly are convenient and can be replaced according to different blades, which greatly increases the versatility of the device. A grinding disc 5034 is fixed to the bottom of the driven rod 5033. A positioning hole coaxial with the moving rod 404 is opened at the bottom of the grinding disc 5034. The positioning hole is adapted to the moving rod 404.

[0030] In this embodiment, the drive motor 505 drives the active rod 5031 to rotate, which in turn drives the driven rod 5033 on it to rotate. Combined with the downward pressure of the electric push rod 502, both sides of the blade can be effectively ground, thus improving the grinding efficiency.

[0031] Understandably, during use, since the blade has friction between both the stabilizer 401 and the grinding disc 5034, the blade's rotation speed is between that of the stabilizer 401 and the grinding disc 5034. This speed difference allows for effective grinding of the blade.

[0032] All electrical components mentioned in this article are electrically connected to the controller and power supply. The control method of this utility model is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0033] The working principle of the above embodiments is as follows:

[0034] In use, first place the blade on the stabilizing base 401, then start the electric actuator 502 and close the movable door simultaneously. The electric actuator 502 causes the moving plate 504 to move down, which in turn drives the drive motor 505 to move down until the grinding disc 5034 comes into contact with the top of the blade. Due to the left and right movement of the telescopic rod 402, the moving rod 404 can also move down accordingly. Then start the drive motor 505, which causes the grinding disc 5034 to rotate rapidly. Through the cooperation of the stabilizing base 401 and the grinding disc 5034, both sides of the blade can be effectively ground simultaneously, thereby effectively improving the blade grinding speed. Furthermore, both the stabilizing base 401 and the driven rod 5033 are detachable structures, which can be replaced according to different blades to accommodate more different blades.
