Abstract
Description
Technical Field
[0001] This utility model relates to the field of concrete viscosity modifier production technology, and in particular to a quantitative feeding mechanism for preparing viscosity modifier raw materials. Background Technology
[0002] Concrete viscosity modifiers are important building material additives widely used in various concrete projects. To ensure the quality and performance of concrete viscosity modifiers, the raw material ratio and feeding amount must be precisely controlled during the production process.
[0003] The prior art can be referenced in Chinese Patent No. CN222034590U, which discloses a quantitative feeding mechanism for raw materials used in the production of concrete viscosity modifiers. This mechanism includes a hopper for holding the raw materials, a discharge port on the bottom side of the hopper with a solenoid valve, and a horizontally movable and rotatable measuring cylinder below the hopper for measuring the single-time dispensing amount of raw materials for the concrete viscosity modifier. The upper end of the measuring cylinder is open and flush with the bottom of the hopper. However, when the raw materials are poured into the measuring cylinder until the space above the limiting plate is filled, the top of the raw materials tends to bulge, resulting in a larger actual amount of raw materials than measured by the measuring cylinder. This affects the accuracy of the quantitative feeding. Therefore, this invention provides a quantitative feeding mechanism for raw materials used in the preparation of viscosity modifiers.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Example 1, referring to Figure 1-4 A quantitative feeding mechanism for raw materials used in the preparation of viscosity modifiers includes a storage hopper 1. Two connecting rods 19 are symmetrically fixed to the bottom of the outer wall of the storage hopper 1. The lower ends of the two connecting rods 19 are connected to a receiving bucket 5. A U-shaped frame 9 is fixed to one side of one of the connecting rods 19. A moving component is installed on the U-shaped frame 9. A first servo motor 14 is installed on the moving component. The output end of the first servo motor 14 is connected to a bottomless measuring cylinder 8 with scale lines. An adjustment component is provided on the bottomless measuring cylinder 8. A leveling component is provided at the top of the bottomless measuring cylinder 8.
[0023] A support plate 15 is fixed to the top of the outer wall of the flattening component. A first electric push rod 16 is connected to the upper end of the support plate 15. A flattening rod 17 is connected to one end of the first electric push rod 16.
[0024] The bottom of the storage hopper 1 is connected to a solenoid valve 2, and the solenoid valve 2 is located above the receiving bucket 5.
[0025] The moving component includes a threaded rod 10 rotatably mounted between the two ends of a U-shaped frame 9 via bearings, a movable seat 13 screwed onto the threaded rod 10, a guide rod 11 fixed between the two ends of the U-shaped frame 9, the bottom of the movable seat 13 slidably sleeved on the guide rod 11, a second servo motor 3 fixed to one end of the U-shaped frame 9, and the output end of the second servo motor 3 connected to one end of the threaded rod 10.
[0026] The first servo motor 14 is fixed on one side of the top of the moving base 13, and the bottomless measuring cylinder 8 is located on the other side of the top of the moving base 13.
[0027] A connecting block 20 is fixed to the top of the outer wall of the storage hopper 1. The connecting block 20 is provided with a connecting hole. Bolts are used to connect the connecting block 20 to the external support through the connecting hole to fix the storage hopper 1.
[0028] The solenoid valve 2 is opened by an external control switch, allowing the raw material to fall into the material-containing space of the bottomless measuring cylinder 8. Then, the solenoid valve 2 is closed, and the first electric push rod 16 is controlled to push the push rod 17, pushing the excess raw material accumulated at the top of the bottomless measuring cylinder 8 away from the bottomless measuring cylinder 8 and falling into the receiving bucket 5, thereby ensuring that the amount of raw material contained in the bottomless measuring cylinder 8 is the actual required amount. The second servo motor 3 drives the threaded rod 10 to rotate, causing the threaded rod 10 to drive the moving seat 13 to move to the limit position, thereby moving the bottomless measuring cylinder 8 to the outside of the receiving bucket 5. The first servo motor 14 drives the bottomless measuring cylinder 8 to rotate, causing the bottomless measuring cylinder 8 to invert and discharge the raw material into the production equipment, realizing the feeding.
[0029] Example 2 is an optimization based on Example 1. Specifically, the adjustment component includes an adjustment plate 12 that is slidably engaged with the inner wall of the bottomless measuring cylinder 8. The lower end of the adjustment plate 12 is connected to a vertical rod 7, and the lower end of the vertical rod 7 is connected to a horizontal rod 6. Two ear plates 18 are symmetrically fixed at the top of the outer wall of the bottomless measuring cylinder 8. A second electric push rod 4 is fixed between each of the two ear plates 18 and both ends of the horizontal rod 6.
[0030] The two second electric push rods 4 are synchronously extended and retracted by an external control switch, which in turn drives the horizontal rod 6, the vertical rod 7 and the adjusting plate 12 to rise and fall. The adjusting plate 12 rises and falls in the bottomless measuring cylinder 8 and, in conjunction with the scale lines on the bottomless measuring cylinder 8, raises and lowers the adjusting plate 12 to the corresponding capacity scale, thus completing the adjustment of the material holding space.
[0031] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
