Description

Technical Field

[0001] The utility model relates to the technical field of grinders, in particular to a feeding device for a grinder. Background Art

[0002] The development of modern coatings requires more and more wet powders that are easy to pump and operate in a dust-free manner as raw materials. From a macroscopic and practical perspective, particles are the smallest constituent unit of powders. The particle size of coating powders has an important influence on the optical properties, tinting power, tinting power, hiding power and other properties of the coating. Therefore, grinding equipment that controls the particle size of coatings is one of the important equipment widely used in coating production.

[0003] However, the existing paint grinders tend to accumulate the ground paint in the discharge port, causing the discharge port to be blocked. At present, the staff usually knocks on the discharge port to make the ground paint continue to fall, but the knocking effect is not good enough. It often takes multiple knocks to make the ground paint continue to be discharged, and frequent knocking is also very troublesome. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the above technical difficulties and provide a grinding machine feeding device, which is designed with a structure specially designed to prevent feeding blockage, thereby ensuring smooth feeding.

[0005] In order to solve the above technical problems, the technical solution provided by the utility model is:

[0006] A grinding machine unloading device, comprising:

[0007] The grinding box has a filling hopper on one side of the top and a discharge pipe at the bottom;

[0008] The grinding mechanism comprises a motor, a grinding shaft, a grinding pestle and a mortar; the top of the grinding shaft is rotatably connected to the top wall of the grinding box, and after the top extends to the outside of the grinding box, it is driven and connected to the motor installed and fixed on the top of the grinding box, the grinding pestle is sleeved and fixed on the grinding shaft, and the bottom wall of the grinding box forms a mortar that matches the grinding pestle;

[0009] The material discharge mechanism includes a spiral blade; the bottom end of the grinding shaft extends to the lower part of the discharge pipe, and the spiral blade is sleeved and fixed on the part located on the discharge pipe;

[0010] The discharge valve mechanism includes a discharge barrel, a second motor, a rotating shaft and a material-discharging plate; a cylindrical discharge barrel is formed at the bottom of the discharge pipe, and the rotating shaft is rotatably connected between the front and rear barrel walls of the discharge barrel. After the rear end of the rotating shaft extends to the outside of the discharge barrel, it is driven and connected to the second motor installed and fixed on the rear side of the discharge barrel. At least three material-discharging plates are evenly fixed on the rotating shaft along the circumference, and the material-discharging plates are movably connected to the circumference and side inner walls of the discharge barrel respectively.

[0011] As an improvement, the grinding pestle is a disc structure, and the top surface gradually tilts downward from the middle to the surroundings, so that the paint to be ground on the upper side of the grinding pestle can enter between the grinding pestle and the mortar more smoothly.

[0012] It is worth mentioning that the motor 1 and the motor 2 used in the present technical solution are both existing devices well known to those skilled in the art, and the use and control methods are both existing technologies.

[0013] The advantages of the utility model compared with the prior art are:

[0014] 1. When the present invention is in use, the motor drives the grinding pestle to rotate and grind, and at the same time, it also drives the spiral blade to rotate, thereby promoting the smooth discharge of the ground paint raw materials from the discharge pipe.

[0015] 2. When the new model is in use, the discharge valve mechanism can not only play the role of a valve, but also further promote the smooth discharge of the ground paint raw materials from the discharge pipe. BRIEF DESCRIPTION OF THE DRAWINGS
