Description

Technical Field

[0001] The utility model belongs to the technical field of horizontal sand mills, in particular to a horizontal sand mill capable of controlling the grinding amount. Background Art

[0002] Horizontal sand mill is a high-efficiency wet ultrafine grinding and dispersing machine widely used in non-metallic mineral industries such as coatings, dyes, paints, inks, medicines, magnetic powders, ferrites, photographic films, pesticides, papermaking and cosmetics. Horizontal sand mill is particularly suitable for dispersing and grinding products with high viscosity and fine particle size requirements, but horizontal sand mill has problems such as inconvenient feeding and insufficient grinding.

[0003] Horizontal sand mills are widely used in the paint industry. When the existing devices are in use, the paint flow is controlled by a solenoid valve during the grinding process. When the paint flows through the solenoid valve without being ground, it will cause blockage inside the solenoid valve, affecting the subsequent flow of the paint. Over time, the solenoid valve will be completely blocked and need to be replaced, thereby increasing costs. Summary of the invention

[0004] The utility model aims to provide a horizontal sand mill capable of controlling the grinding amount, so as to realize the quantitative conveying of the coating and grind the coating more finely and evenly.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is as follows: a horizontal sand mill with controllable grinding amount is provided, comprising a workbench, an adjusting mechanism is arranged on the top of the workbench, the adjusting mechanism comprises a grinding box, an adjusting motor is fixedly connected to the top of the workbench, a screw rod is fixedly connected to the output end of the adjusting motor, an adjusting plate is threadedly connected to the outer wall of the screw rod, a limiting hole is arranged inside the adjusting plate, and there are two limiting holes, a limiting rod is fixedly connected to the top of the workbench, and there are two limiting rods, two limiting rods are respectively located inside the two limiting holes, a fixing column is fixedly connected to the outer wall of the adjusting plate, a slide groove is arranged on the outer wall of the grinding box, and there are two slide grooves, sliders are installed inside the two slide grooves, a linkage block is fixedly connected to the outer wall of the slider, an L-shaped bracket is fixedly connected to the outer wall of the linkage block, a linkage groove is arranged inside the L-shaped bracket, the fixing column passes through the two linkage grooves in sequence, and baffles are fixedly connected to the tops of the two limiting rods.

[0006] Optionally, a grinding motor is fixedly connected to the outer wall of the grinding box, a grinding paddle is fixedly connected to the output end of the grinding motor, and the grinding paddle is located inside the grinding box.

[0007] Optionally, a connection block is fixedly connected to the outer wall of the grinding paddle, and there are multiple connection blocks, and the outer walls of the multiple connection blocks are all fixedly connected to a scraper.

[0008] Optionally, a material rack is fixedly connected to the top of the workbench, a material barrel is fixedly connected to the top of the material rack, a guide tube is fixedly connected to the outer wall of the material barrel, and the other end of the guide tube is fixedly connected to the outer wall of the grinding box.

[0009] Optionally, the bottom of the workbench is fixedly connected with a supporting foot, and the number of the supporting feet is multiple, and the outer walls of two adjacent supporting feet are fixedly connected with a supporting frame, and the number of the supporting frames is multiple.

[0010] Optionally, the outer wall of the grinding box is movably connected with a flap, and there are two flaps, and the outer walls of the two flaps are fixedly connected with handles.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The utility model is provided with an adjusting motor. When the adjusting motor is running, the output end of the adjusting motor drives the screw rod to rotate, thereby driving the adjusting plate to rise and fall, and two limit holes are arranged inside the adjusting plate, and the two limit rods are respectively located in the two limit holes, so that the lifting process of the adjusting plate is smoother. When the adjusting plate rises, it drives the fixed column, and the fixed column passes through the two linkage grooves in turn. When the fixed column moves, the two L-shaped brackets respectively drive the two linkage blocks and the slider to approach each other, blocking the paint from flowing from the guide pipe into the grinding box. After the grinding is completed, the sliders can be made to deviate from each other, and the paint continues to enter the grinding box along the guide pipe, so that the flow rate of the paint can be controlled in real time, and then the grinding amount of the paint in the grinding box can be controlled, so that the paint can be ground more finely and evenly. In the existing device, the paint is used to control the flow rate of the paint by an electromagnetic valve during the grinding process. When the paint flows through the electromagnetic valve without being ground, it will cause the inside of the electromagnetic valve to be blocked, affecting the flow rate of the subsequent paint, and over time it will cause the electromagnetic valve to be completely blocked, requiring replacement, which increases the cost.

[0013] 2. The utility model has multiple connection blocks fixedly connected to the outer wall of the grinding paddle, and the multiple connection blocks are fixedly connected to scrapers. When the grinding paddle rotates, the scrapers are driven to rotate along the inner wall of the grinding box to prevent the paint from adhering to the inner wall of the grinding box; by arranging multiple support frames in coordination with multiple legs and utilizing the stability of the triangle, the workbench is made more stable; by arranging two flip covers, it is convenient to add grinding media to the grinding box.
