Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0026] refer to Figure 1-6 Now, a vertical sand mill provided by an embodiment of the utility model is described. A vertical sand mill comprises a bottom plate 1, a support seat 2 is fixedly connected to the upper end of the bottom plate 1, a support ring 12 is fixedly connected inside the support seat 2, a sand mill barrel 6 is rotatably connected inside the support ring 12, and an end cover 7 is arranged on the upper end of the sand mill barrel 6; a lifting mechanism 3 is arranged on the rear side of the upper end of the bottom plate 1, a power mechanism 4 and a moving plate 5 are arranged at the front end of the lifting mechanism 3, a fixed shaft 13 is rotatably connected inside the moving plate 5, the lower end of the fixed shaft 13 passes through the end cover 7, and is slidably connected to the end cover 7, a sand mill disc 14 and a stirring blade 15 are fixedly connected to the circumferential surface of the fixed shaft 13, and the stirring blade 15 is located at the bottom of the fixed shaft 13; a discharge pipe 8 is rotatably connected to the lower end of the sand mill barrel 6, one end of the discharge pipe 8 away from the sand mill barrel 6 passes through the support seat 2, and is fixedly connected to the support seat 2, and a valve 16 is installed on the discharge pipe 8.

[0027] Specifically, the movable plate 5 is driven to rise by the lifting mechanism 3, and the sanding disc 14 and the stirring blade 15 are driven to rise with the cooperation of the fixed shaft 13, so that the sanding disc 14 and the stirring blade 15 are located at the upper end of the sanding barrel 6, so as to facilitate the addition of the liquid material to be ground and the grinding medium into the sanding barrel 6. After the addition is completed, the lifting mechanism 3 descends, driving the sanding disc 14 and the stirring blade 15 to enter the sanding barrel 6. The sanding disc 14 grinds the liquid material with the cooperation of the grinding medium. When the end cover 7 is in close contact with the sanding barrel 6, the lifting mechanism 3 stops descending, and the power mechanism 4 works to drive the sanding disc 14 to rotate at a high speed. At the same time, the power mechanism 4 drives the sanding barrel 6 to rotate. Since the rotation direction of the sanding barrel 6 is opposite to that of the sanding disc 14, the sanding disc 14 can quickly contact with the liquid material, so that the liquid material can be ground faster, thereby improving the grinding efficiency. When the grinding of the liquid material is completed, the valve 16 is opened to discharge the liquid material from the discharge pipe 8.

[0028] The lifting mechanism 3 includes a support column 301, a screw rod 302, a first motor 303 and a slider 304. The upper end of the base plate 1 is fixedly connected to the support column 301, and the screw rod 302 is rotatably connected inside the support column 301. The upper end of the support column 301 is fixedly connected to the first motor 303, and the output end of the first motor 303 is fixedly connected to the screw rod 302. The circumferential surface of the screw rod 302 is threadedly connected to the slider 304. The slider 304 is slidably connected to the support column 301, and the front end of the slider 304 is fixedly connected to the moving plate 5. When working, the first motor 303 is started, and the slider 304 is driven to slide inside the support column 301 under the action of the screw rod 302, thereby facilitating the moving plate 5 to move up and down.

[0029] The power mechanism 4 includes a transmission rod 401, a rotating cylinder 402, a driving wheel 403, a driven wheel 404, a belt 405, a bearing seat 406, a rotating shaft 407, a gear 408, a gear ring 409, a second motor 410 and a fixed plate 411. The front end of the support column 301 is fixedly connected to the fixed plate 411, and the upper end of the fixed plate 411 is fixedly connected to the second motor 410. The output end of the second motor 410 passes through the fixed plate 411 and is rotatably connected to the fixed plate 411. The output end of the second motor 410 is fixedly connected to the transmission rod 401; the rotating cylinder 402 is rotatably connected to the inside of the movable plate 5, and the rotating cylinder 402 is slidably connected to the transmission rod 401. The circumferential surface of the rotating cylinder 402 is fixedly connected to the driving wheel 403; the upper end of the fixed shaft 13 is fixedly connected to the driven wheel 404, and the driven wheel 404 and the driving wheel 403 are connected by a belt 405; the circumference of the support ring 12 The surface is fixedly connected with a bearing seat 406, and a rotating shaft 407 is rotatably connected inside the bearing seat 406. The upper end of the rotating shaft 407 is fixedly connected to the transmission rod 401, and a gear 408 is fixedly connected to the circumferential surface of the rotating shaft 407. The gear 408 is meshed with a toothed ring 409, and the toothed ring 409 is fixedly connected to the sanding barrel 6. When working, the second motor 410 works, and the output end of the second motor 410 drives the transmission rod 401 to rotate, and drives the fixed shaft 13 to rotate at a high speed under the cooperation of the rotating cylinder 402, the driving wheel 403, the driven wheel 404 and the belt 405, thereby driving the sanding disc 14 to rotate at a high speed, and then grinding the liquid material; at the same time, the sanding barrel 6 is driven to rotate under the cooperation of the rotating shaft 407, the gear 408 and the toothed ring 409, so that the rotation direction of the sanding barrel 6 is opposite to the rotation direction of the sanding disc 14, so that the liquid material contacts the sanding disc 14 faster, thereby improving the grinding efficiency.

[0030] The end faces of the transmission rod 401 and the through hole inside the rotating cylinder 402 are both square. When working, since the end faces of the transmission rod 401 and the through hole inside the rotating cylinder 402 are both square, it is easy to drive the rotating cylinder 402 to rotate.

A spring 11 is provided on the circumferential surface of the moving rod 9, and one end of the spring 11 is fixedly connected to the baffle 10, and the other end of the spring 11 is fixedly connected to the moving plate 5. Since the contact position between the end cover 7 and the sanding barrel 6 is provided with the rotating ring 17, during operation, when the end cover 7 contacts the sanding barrel 6, the wear on the end cover 7 and the sanding barrel 6 can be reduced as the sanding barrel 6 rotates; at the same time, when the end cover 7 contacts the sanding barrel 6, with the cooperation of the moving rod 9, the spring 11 and the baffle 10, the end cover 7 can also be prevented from hard contact with the sanding barrel 6, which is beneficial to protecting the sanding barrel 6.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
