However, when the existing oil drum capping machine is in use, since the oil drum capping machine is usually designed for oil drum covers of a specific size range, if encountering oil drum covers with large size differences, such as industrial large oil drum covers and small household oil drum covers interchangeably, the capping machine may not be effectively adapted, which limits the versatility of the capping machine. Users need to purchase capping machines of multiple different sizes to cope with different types of oil drum covers, which increases costs and inconveniences. Summary of the invention

DETAILED DESCRIPTION

[0018] The present invention is further described below in conjunction with specific embodiments.

[0019] Example 1 like Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, an oil drum capping device provided by the present invention comprises a handle 1 and a rotating part 2, one end of the handle 1 is fixedly connected to an L-shaped connecting frame 3 by a thread, the bottom of the L-shaped connecting frame 3 is fixedly connected to a fixing device, the rotating part 2 is movably connected to the side wall of the fixing device, the fixing device comprises a fixing frame 4, a driving member and two limit blocks 5, the fixing frame 4 is fixedly connected to the bottom of the L-shaped connecting frame 3, and the end of the fixing frame 4 away from the L-shaped connecting frame 3 is fixedly connected to a rotating shaft 6, one end of the rotating shaft 6 is fixedly connected to a concave cam 7, the driving member is fixedly connected to the end of the rotating shaft 6 away from the concave cam 7, the bottom of the two limit blocks 5 are respectively fixedly connected to two sliding blocks 8, the two sliding blocks 8 are respectively slidably connected to the inner wall of the slide groove opened at the bottom of the fixing frame 4, the two ends of the two limit blocks 5 are respectively fixedly connected to a plurality of fixing rods 9, and tension springs 10 are fixedly connected between the plurality of fixing rods 9, the driving member is a fixing column 11 and The lever 12 and the fixed column 11 are fixedly connected to one end of the rotating shaft 6 away from the concave cam 7, the lever 12 is fixedly connected to one end of the fixed column 11, and the lever 12 is movably connected to the inner wall of the groove opened at one end of the fixed frame 4, the rotating part 2 includes a convex rotary capping head 13 and a concave rotary capping head 14, the inner walls of the grooves opened by the convex rotary capping head 13 and the concave rotary capping head 14 are fixedly connected to the limiting frame 19, the concave rotary capping head 14 is fixedly connected to the bottom of the convex rotary capping head 13, the outer surface of the convex rotary capping head 13 is fixedly connected with a plurality of uniformly arranged limiting columns 15, the outer surface of the concave rotary capping head 14 is provided with a plurality of uniformly arranged limiting grooves 16, the outer surface of the handle 1 is provided with anti-slip grooves, the handle 1 and the L-shaped connecting frame are both made of copper alloy, the convex rotary capping head 13 and the concave rotary capping head 14 are both made of polycarbonate material, the slider is T-shaped, and the size of the slider 8 matches the size of the slide groove opened at the bottom of the fixed frame 4; It should be noted that the handle 1 is fixedly connected to the L-shaped fixing frame 4 by means of a thread. This connection method is convenient for installation and disassembly, and can ensure the relative stability of the structure during normal use, so that the various components of the entire capping device work together during operation and will not easily become loose. At the same time, the male screw capping head 13 and the female screw capping head 14 are both made of polycarbonate material. The polycarbonate screw capping head has good transparency and glossiness. The screw capping head made of this material looks more beautiful and has advantages in some cases where the screw capping process needs to be observed. When there are some special structures inside the screw capping head or the contact with the oil drum cover needs to be checked, the transparent polycarbonate screw capping head can facilitate direct observation by the user. Moreover, the handle 1 and the L-shaped connecting frame 3 are both made of copper alloy. The copper alloy can significantly improve the hardness, strength and wear resistance of the material by doping with other elements, so that the handle 1 and the L-shaped connecting frame 4 of the oil drum cap screw can withstand greater torque and pressure, and are not easily deformed or damaged, thereby extending the service life of the product; When the barrel cover on the oil barrel needs to be removed during use, the male screw capping head 13 or the female screw capping head 14 is first engaged with the inner diameter of the barrel cover to be removed, and then the fixing device and the screw capping head are driven to rotate by rotating the handle 1 and the L-shaped connecting frame 3, so as to remove the barrel cover on the oil barrel; It should be noted that when removing the barrel cover, the barrel cover on the oil barrel is opened based on the principle of leverage. The core of the lever principle is to save effort or change the direction of force through the action of the lever arm around a fulcrum. In many cases, rotational motion can use the lever principle to achieve more labor-saving operations. When an object rotates around a fixed point, if force is applied at the right position, it can be regarded as a lever at work. In the process of opening the barrel cover on the oil barrel, the rotation of the handle 1 can be regarded as a deformed lever motion. The rotation center of the handle 1 is equivalent to the fulcrum of the lever. When we rotate the handle 1, the distance from the point of application of the applied force to the fulcrum and the distance from the point of application of the resistance on the edge of the oil barrel cover to the fulcrum together constitute a lever system; Furthermore, when the capping head of the oil drum capping machine needs to be replaced during use, the lever 12 is firstly moved, and the rotating shaft 6 is driven to rotate by the lever 12 and the fixing column 11, and the concave cam 7 is driven to rotate by the fixing column 11. At this time, the limit blocks 5 and the tension spring 10 provided on both sides of the concave cam 7 will return to their original positions due to the loss of the extrusion force generated by the concave cam 7, and lose the limit on the limit frame 19, so that the capping head can be removed, and then the capping head to be used is aligned with the fixing frame 4, and then the lever 12 is moved in the opposite direction. At this time, the fixing column 11 and the rotating shaft 6 are driven to rotate by the lever 12, and the limit frame 19 provided on the capping head is fixed by the limit blocks 5.

[0020] Example 2 refer to Figure 5 As shown, following the same structure as detailed in Example 1, the difference from Example 1 is that the driving member is a servo motor 17, the servo motor 17 is fixedly connected to the inside of the fixing frame 4, and the output end of the servo motor 17 is fixedly connected to the end of the rotating shaft 6 away from the concave cam 7. The rotating shaft 6 is driven by the set servo motor 17, and the concave cam 7 is driven to rotate. The servo motor 17 can provide very precise speed and position control to ensure that the motion trajectory and position of the concave cam 7 are very accurate, and the servo motor 17 can change the speed and torque by adjusting parameters to adapt to different workloads and operating requirements.

[0021] Example 3 refer to Figure 6 As shown, following the same structure as detailed in Example 1, the difference from Example 1 is that both ends of the two limit blocks 5 are fixedly connected with an insertion rod 18, and a through hole matching the insertion rod 18 is opened on the limit frame 19. Through the set insertion rod 18, during the movement of the limit block 5, the insertion rod 18 will be inserted into the inner wall of the through hole opened on the limit frame 19, thereby fixing the limit frame 19, and limiting the limit frame 19 by the insertion rod 18 can provide additional support and fixing effect, thereby reducing the shaking or displacement of the limit frame 19 during operation.
