[0020] The utility model provides Figure 1-5The variable speed feeding device of a grinder shown in the figure comprises a charging funnel 1, a horizontal plate 2 is fixedly installed in the charging funnel 1, an adjusting screw 3 is threadedly installed on the horizontal plate 2, a conical column 4 is fixedly installed on the bottom end of the adjusting screw 3, and a first rotating handle 5 is fixedly installed on the top end of the adjusting screw 3. The first rotating handle 5 is rotated to drive the conical column 4 to move, and the size of the bottom opening of the charging funnel 1 is adjusted, so that the amount of coffee beans passing through the opening per unit time changes, thereby achieving the feeding speed adjustment of the coffee beans. Two limit installation grooves 6 are provided, and rotating screws 7 are rotatably installed in the two limit installation grooves 6, and the top ends of the two rotating screws 7 extend to the outside of the charging funnel 1, and the two rotating screws 7 are respectively threadedly installed with limit connection plates 8, and one side of the two limit connection plates 8 extends to the outside of the corresponding limit installation grooves 6, and is respectively slidably connected with the inner wall of the corresponding limit installation grooves 6, and the bottom of the two limit connection plates 8 is respectively fixedly installed with vertical plates 9, and the two vertical plates 9 are respectively slidably installed with sliding rods 10. In order to reduce the sliding The friction between the rod 10 and the vertical plate 9 reduces the wear of the sliding rod 10 and increases the service life of the sliding rod 10. Through holes are respectively opened on the two vertical plates 9. Linear bearings are fixedly installed in the two through holes. The two sliding rods 10 penetrate the two linear bearings respectively and are slidably connected to the inner walls of the two linear bearings respectively. The two sliding rods 10 are fixedly installed with connecting arc plates 11 at one end respectively. The outer walls of the two connecting arc plates 11 are fixedly installed with arc rubber clamps 12 respectively. The two arc rubber clamps 12 The clamping wall gradually expands from top to bottom. Since the clamping wall of the arc-shaped rubber clamping plate 12 is inclined downward, the arc-shaped rubber clamping plate 12 can clamp the charging barrel of the funnel-type coffee grinder more stably. Compression springs 13 are movably sleeved on the two sliding rods 10, and one end of the two compression springs 13 is fixedly connected to the corresponding connecting arc plate 11, and the other end of the two compression springs 13 is fixedly connected to the corresponding vertical plate 9. In order to improve the service life of the compression springs 13, the two compression springs 13 are tin-plated springs.

[0022] In order to clean the impurities and fine particles adhered to the surface of the adjusting screw 3 and prevent the impurities and fine particles from causing the adjusting screw 3 to slip during rotation, resulting in the adjusting screw 3 being unable to rotate and affecting the working efficiency, thread grooves 16 are respectively provided on the top and bottom of the cross plate 2, and threaded rods 17 are respectively threadedly installed in the two thread grooves 16, and cleaning brush rollers 19 are respectively fixedly installed at the ends of the two thread rods 17 away from each other.

[0023] In order to prevent fine particles and impurities from entering the thread groove 16 and causing thread slippage when the threaded rod 17 rotates in the thread groove 16, causing unnecessary trouble, dustproof sponge rings 18 are fixedly mounted on the two threaded rods 17, and the two dustproof sponge rings 18 are in close contact with the cross plate 2.

[0024] The working principle of the variable speed feeding device for a grinder provided by the utility model is as follows: in the initial state, the compression spring 13 is in a compressed state. When the device needs to be used, the charging funnel 1 is first placed on the top of the charging barrel of the coffee grinder. Since the charging funnel 1 is larger at the top and lower at the bottom, the bottom part of the charging funnel 1 will enter the charging barrel, and the top of the charging funnel 1 will be located above the charging barrel. The two second rotating handles 15 are rotated. The rotation of the second rotating handles 15 drives the rotating screw 7 to rotate. The rotation of the rotating screw 7 drives the limit connecting plate 8 to move downward. The movement of the limit connecting plate 8 drives the vertical plates 9 to approach each other. The two vertical plates 9 approach each other and drive the two sliding rods 10 to approach each other. The two vertical plates 9 approach each other and drive the two connecting arc plates 11 to approach each other. The two connecting arc plates 11 approach each other and drive the arc rubber clamps 12 to approach each other and contact the charging barrel and squeeze the charging barrel, thereby fixing the device on the charging barrel, and then pouring the coffee beans into the charging funnel 1. When it is necessary to adjust the feeding speed of coffee beans, the first rotating handle 5 is turned, and the rotation of the first rotating handle 5 drives the adjusting screw 3 to rotate and move. The movement of the adjusting screw 3 drives the conical column 4 to move, and the size of the opening at the bottom of the charging funnel 1 is adjusted, so that the amount of coffee beans passing through the opening per unit time changes, thereby completing the adjustment of the feeding speed of coffee beans, so that the coffee beans enter the coffee grinder evenly, the coffee beans are ground more fully, and the taste of coffee is improved. At the same time, when the adjusting screw 3 is rotated and moved, the cleaning brush roller 19 cleans the impurities and fine particles adhered to the surface of the adjusting screw 3 to prevent the impurities and fine particles from causing the adjusting screw 3 to slip when rotating, resulting in the adjusting screw 3 being unable to rotate and affecting the work efficiency. When it is necessary to replace the cleaning brush roller 19, the cleaning brush roller 19 is rotated counterclockwise to drive the threaded rod 17 to rotate and move outward, and then the cleaning brush roller 19 is removed from the device and then replaced. The process is simple, fast and efficient.

[0025] Compared with the related art, the variable speed feeding device of the grinding machine provided by the utility model has the following features:

[0026] Beneficial effects:

[0027] The utility model provides a variable speed feeding device for a grinder. A loading funnel 1 is first placed on the top of a loading barrel of a coffee grinder. Two second rotating handles 15 are rotated to drive arc-shaped rubber clamping plates 12 to approach each other and contact the loading barrel and squeeze the loading barrel. The device is fixedly installed on the loading barrel, and coffee beans are poured into the loading funnel 1. The first rotating handle 5 is rotated to drive the conical column 4 to move, and the size of the bottom opening of the loading funnel 1 is adjusted, so that the amount of coffee beans passing through the opening per unit time is changed, thereby achieving the adjustment of the feeding speed of the coffee beans. The coffee beans are evenly fed into the coffee grinder, the coffee beans are ground more fully, and the taste of the coffee is improved. At the same time, when the adjusting screw 3 rotates and moves, the cleaning brush roller 19 cleans the impurities and fine particles adhered to the surface of the adjusting screw 3 to prevent the impurities and fine particles from causing the adjusting screw 3 to slip when rotating, resulting in the adjusting screw 3 being unable to rotate and affecting the work efficiency. The cleaning brush roller 19 is driven by counterclockwise rotation to drive the threaded rod 17 to rotate and move outward, and then the cleaning brush roller 19 is removed from the device and replaced. The process is simple, fast and efficient.
