Description

Technical Field

[0001] The utility model relates to the technical field of gun clay production, and particularly relates to a metering and feeding mechanism of a waterless gun clay batching machine. Background Technique

[0002] Waterless gun clay generally uses corundum, bauxite, clay, sericite, asphalt, silicon carbide, coke powder, etc. as raw materials, and uses tar, resin, etc. as binders. During the production of waterless gun clay, various raw materials need to be added in a fixed proportion. In the traditional batching method, accurate metering cannot be carried out, and manual visual inspection or simple tools are often used for measurement, which is time-consuming, laborious and has large errors;

[0003] In addition, in the prior art, after the various raw materials are proportioned, they are directly added to the extruder without mixing. The main function of the extruder is extrusion molding, and the stirring and mixing effect is average. Therefore, the components of the extruded gun clay are uneven, affecting the quality of the gun clay. Content of the Utility Model

Detailed Embodiments

[0027] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other implementation manners obtained by those of ordinary skill in the art based on the embodiments of the present utility model without any creative efforts fall within the scope protected by the present utility model.

[0028] See Figures 1 - 4 As shown, the present utility model provides a metering and feeding mechanism for an anhydrous clay gun, including a fixed platform 1. A plurality of material bins 4 are fixedly arranged on the upper side of the fixed platform 1 for placing different raw materials. The bottom of the material bin 4 is communicated with an impeller assembly 20 for outputting the materials in the material bin 4.

[0029] A mixing mechanism 3 is arranged on the fixed platform 1 for mixing different raw materials.

[0030] A first adjusting assembly 2 is arranged on the fixed platform 1 for adjusting the inclination of the mixing mechanism 3.

[0031] Weighing devices 6 with the same number as the material bins 4 are arranged on the fixed platform 1. A second adjusting assembly 5 is arranged on the fixed platform 1 for adjusting the angle of the weighing devices 6. A receiving hopper 7 is arranged on the weighing end of the weighing device 6. The receiving hopper 7 corresponds to the bottom of the impeller assembly 20, and the open side of the receiving hopper 7 corresponds to the mixing mechanism 3.

[0032] As an optional implementation manner, the impeller assembly 20 includes a housing 21. The housing 21 is fixed at the bottom of the material bin 4 and is communicated with the material bin 4. An opening is arranged at the bottom of the housing 21, and the opening corresponds to the receiving hopper 7. A rotating shaft 22 is rotatably arranged in the housing 21. An impeller 23 is fixed on the rotating shaft 22, and the surface of the impeller 23 is in clearance fit with the inner wall of the housing 21. A motor 24 is arranged on the housing 21, and the output shaft of the motor 24 is fixed to the end of the rotating shaft 22 for rotating the rotating shaft 22.

[0033] By rotating the impeller 23 through the motor 24, the raw materials are carried through the clearance of the impeller 23. The raw materials can follow the rotation of the impeller 23. When the raw materials follow the rotation of the impeller 23 to the opening at the bottom of the housing 21, they can fall into the receiving hopper 7 by themselves.

[0034] The mixing mechanism 3 includes a stirring tank 13. A stirring roller 12 is rotatably arranged in the stirring tank 13. One end of the stirring tank 13 is closed and the other end is open. A fixing plate 11 is rotatably arranged at the end of the stirring roller 12 corresponding to the open side of the stirring tank 13. The fixing plate 11 is fixed on the stirring tank 13. The other end of the stirring roller 12 is rotatably connected to the closed side of the stirring tank 13 and passes through the stirring tank 13. A reduction motor 15 is fixed on the stirring tank 13. The output shaft of the reduction motor 15 is fixed to the end of the stirring roller 12 for rotating the stirring roller 12. The upper side of the stirring tank 13 corresponds to the storage hopper 7.

[0035] By rotating the stirring roller 12 with the reduction motor 15, the materials can be mixed by the cooperation of the stirring roller 12 and the stirring tank 13.

[0036] The first adjustment assembly 2 includes a winch 9 and a support arm 14. The support arm 14 and the winch 9 are fixed on the fixed platform 1. The support arm 14 is hinged to the bottom of the stirring tank 13. The lower end of the pulling rope 10 of the winch 9 is fixed to the open side of the stirring tank 13. By releasing the pulling rope 10 with the winch 9, the stirring tank 13 swings downward under the action of gravity.

[0037] The second adjustment assembly 5 includes a support plate 16. Two fixed arms 17 are fixed on the fixed platform 1. One side of the support plate 16 is hinged to the two fixed arms 17. A plurality of weighing devices 6 are arranged on the upper side of the support plate 16. An electric push rod 19 is arranged on the upper side of the fixed platform 1. The movable end of the electric push rod 19 is fixed with a roller 18. The roller 18 contacts the bottom of the support plate 6.

[0038] By driving the roller 18 to move downward with the electric push rod 19, the support plate 16 will swing downward with the hinge point of the fixed arm 17 as the axis.

[0039] The surface of the stirring roller 12 is in clearance fit with the inner wall of the stirring tank 13. The stirring roller 12 has strip-shaped blades. The blades are fixed to the shaft through fixing rods. There is a gap between the blades and the shaft for the raw materials to pass through. By pushing the raw materials with the blades, various raw materials can be fully mixed.

[0040] The upper side of the stirring tank 13 is higher than the stirring roller 12. The upper side of the stirring tank 13 is designed with an expanded open hopper, which is convenient for pouring raw materials into the stirring tank 13. The stirring roller 12 rotates at a low speed to ensure that the stirring roller 12 will not throw the raw materials out of the stirring tank 13.

[0041] There are two electric push rods 19, which are distributed on both sides of the roller 18, so as to improve the stability of the roller 18 and prevent the roller 18 from tilting.

[0042] With the above structure, various raw materials for making gun clay are separately placed in several material bins 4. When the impeller assembly 20 does not rotate, the materials are blocked by the impeller assembly 20 and cannot fall from the material bins 4. When the impeller assembly 20 rotates, it can transfer the materials in the material bins 4 to the receiving hopper 7. The weighing device 6 can detect the amount of materials in the receiving hopper 7, so as to accurately determine the ratio between several raw materials. The second adjustment assembly 5 drives the weighing device 6 and the receiving hopper 7 to tilt towards the mixing mechanism 3, so that the raw materials fall into the mixing mechanism 3. The mixing mechanism 3 mixes different raw materials evenly, and then the first adjustment assembly 2 makes the mixing mechanism 3 tilt towards the feed inlet of the gun clay extruder, so that the raw materials enter the mixing mechanism 3.

[0043] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
