DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0021] Please refer to Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 A schematic structural diagram of a preferred embodiment of a capstan grinder for conveniently adjusting the capstan grinding speed provided by the utility model; Figure 2 for Figure 1 A schematic diagram of the structure of a speed regulating mechanism of a capstan mill for conveniently adjusting the capstan speed is shown; Figure 3 for Figure 1 The front view structural diagram of the speed regulating mechanism of the capstan mill for conveniently adjusting the capstan speed is shown. The capstan mill for conveniently adjusting the capstan speed comprises: a device bottom plate 1 and a speed regulating mechanism 5;

[0022] A mounting seat 2, the mounting seat 2 is fixedly connected to the middle of the upper surface of the device bottom plate 1, and the speed regulating mechanism 5 is arranged on the rear end surface of the mounting seat 2;

[0023] The speed regulating mechanism 5 comprises a rotating block 51 which is rotatably connected to the rear surface of the mounting seat 2 in a transverse direction. The outer surface of the rotating block 51 is fixedly connected to a plurality of extension sleeves 52 along the radial direction of its cross section. The interiors of the plurality of extension sleeves 52 are respectively slidably connected to sliding posts 53 along the length direction thereof. The outer ends of the plurality of sliding posts 53 are fixedly connected to semi-circular arc plates 54. The rear end surface of the rotating block 51 is fixedly connected to an electric control telescopic rod 55 in a transverse direction. The other end of the electric control telescopic rod 55 is fixedly connected to an adjusting block 56. The rear surfaces of the plurality of arc plates 54 are fixedly connected to first linkage seats 57. The other ends of the plurality of first linkage seats 57 are rotatably connected to connecting rods 59. The other ends of the plurality of connecting rods 59 are rotatably connected to second linkage seats 58. The other ends of the plurality of second linkage seats 58 are fixedly connected to the outer surface of the adjusting block 56.

[0024] A plurality of arcuate plates 54 are combined to form a pulley structure.

[0025] Since the multiple arc plates 54 arranged on the outer surface of the rotating block 51 are connected to the rotating block 51 through the sliding column 53, and the sliding column 53 is arranged along the radial direction of the cross-section of the rotating block 51, the multiple arc plates 54 can be moved along the radial direction of the cross-section of the rotating block 51. When it is necessary to adjust the positions of the multiple arc plates 54, the length of the electrically-controlled telescopic rod 55 can be adjusted. During its shortening process, the second linkage seat 58 on its outer surface will drive the first linkage seat 57 to move through the connecting rod 59, and the multiple first linkage seats 57 will drive the multiple arc plates 54 to move outward, so that the outer diameter of the pulley structure composed of the multiple arc plates 54 can be increased, and vice versa. The outer diameter of the pulley structure will be reduced.

[0026] The speed regulating mechanism 5 also includes a driven pulley 510 which is laterally rotatably connected to the other side of the rear end surface of the mounting seat 2. A mounting groove 512 is provided in the middle of the rear end surface of the mounting seat 2. A slider 513 is vertically slidably connected inside the mounting groove 512. A spring 514 is vertically fixedly connected between the bottom end of the slider 513 and the bottom end of the inside of the mounting groove 512. An adjusting pulley 515 is laterally rotatably connected to the outer surface of the slider 513. The pulley structure, the adjusting pulley 515 and the driven pulley 510 are connected by belt transmission.

[0027] In the speed regulating mechanism 5, the pulley structure and the driven pulley 510 are connected by belt transmission, so when the outer diameter of the pulley structure becomes larger, the speed of the driven pulley 510 will become faster when it drives the driven pulley 510 to rotate, and vice versa. When its outer diameter changes, in order to ensure the transmission effect of the belt, the adjusting pulley 515 will always ensure the tension of the belt under the action of the spring 514, so as to ensure the transmission effect of the belt.

[0028] The front end of the upper surface of the device bottom plate 1 is fixedly connected with a mounting frame 3 , the interior of the mounting frame 3 is fixedly connected with a motor 4 , and the output shaft of the motor 4 rotatably passes through the mounting seat 2 and is fixedly connected to the front end surface of the rotating block 51 .

[0029] A capstan structure 6 is provided at the rear end of the upper surface of the device bottom plate 1 .

[0030] A connecting shaft 511 is laterally fixedly connected to the rear end surface of the driven pulley 510 , and the rear end of the connecting shaft 511 is fixedly connected to the input end of the capstan structure 6 .

[0031] The central axes of the connecting shaft 511 and the driven pulley 510 are located on the same straight line.

[0032] In the device, the rotating block 51 can be driven to rotate by the drive of the motor 4, thereby driving the speed regulating mechanism 5 to operate, and then the capstan grinding structure 6 can be driven to operate through the output of the driven pulley 510.

[0033] The working principle of the capstan grinder provided by the utility model for conveniently adjusting the capstan grinding speed is as follows:

[0034] In the device, the plurality of arc-shaped plates 54 arranged on the outer surface of the rotating block 51 are connected to the rotating block 51 through the sliding column 53, and the sliding column 53 is arranged along the radial direction of the cross section of the rotating block 51, so the plurality of arc-shaped plates 54 can move along the radial direction of the cross section of the rotating block 51. When the positions of the plurality of arc-shaped plates 54 need to be adjusted, the length of the electric control telescopic rod 55 can be adjusted. During the shortening process, the second linkage seat 58 on the outer surface thereof will drive the first linkage seat 57 to move through the connecting rod 59, and the plurality of first linkage seats 57 will drive the plurality of arc-shaped plates 54 to move outward. , thereby increasing the outer diameter of the pulley structure composed of multiple arc plates 54, otherwise the outer diameter of the pulley structure will be reduced. In the speed regulating mechanism 5, the pulley structure and the driven pulley 510 are connected by belt transmission, so when the outer diameter of the pulley structure becomes larger, the speed of the driven pulley 510 will become faster when it drives the driven pulley 510 to rotate, otherwise it will become slower. When its outer diameter changes, in order to ensure the transmission effect of the belt, the adjusting pulley 515 will always ensure the tightness of the belt under the action of the spring 514, so as to ensure the transmission effect of the belt.

[0035] Compared with the related art, the capstan grinder provided by the utility model which is convenient for adjusting the capstan grinding speed has the following beneficial effects:

[0036] The utility model provides a capstan grinding machine with convenient adjustment of the capstan grinding speed. By setting a speed regulating mechanism 5, the speed regulating mechanism 5 can be used to adjust the capstan grinding speed when the device is in use. A plurality of arc plates 54 are provided at the outer end of a rotating block 51 in the speed regulating mechanism 5. Since the arc plates 54 are connected to the rotating block 51 through a sliding column 53, the arc plates 54 can move in the radial direction of the cross section of the rotating block 51. Therefore, the pulley structure composed of the plurality of arc plates 54 can arbitrarily change its own radius size, thereby changing the rotation speed of a driven pulley 510 transmitted thereto, thereby achieving a speed regulation effect, so that people can quickly and conveniently perform speed regulation when using the device, thereby improving the practicality of the device.
