Description

Technical Field

[0001] The utility model relates to the technical field of metering devices, and particularly relates to a metering device for a batching bin. Background Art

[0002] The metering device for a batching bin is an important device for accurately measuring and controlling the inflow and outflow of materials (such as powders, granules, liquids, etc.) in industrial production. This device is widely used in many industries such as chemical industry, food processing, pharmaceutical industry, building materials, etc., and is of great significance for ensuring product quality and improving production efficiency.

[0003] At present, for the metering of solid batching, the existing metering devices for batching bins mostly use load cells for weighing and metering. After each weighing and metering, it is necessary to first tilt the metering cylinder, and after complete tilting, then return it to the upright position before the next metering can be carried out. The operations of completely tilting the batching and returning the metering cylinder are additional steps, which will increase the time of the entire metering process. If it is on a large-scale industrial production line where metering operations need to be carried out frequently, and after each metering, the batching needs to be tilted first and then returned to the upright position, this will significantly reduce production efficiency and prolong the production cycle. Based on this, a metering device for a batching bin is proposed here. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a metering device for a batching bin to solve the above deficiencies in the technology.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A metering device for a batching bin, including a support, on the top of which an installation frame is fixed. A batching bin is installed on the installation frame. At the bottom of the support, there are support legs. It further includes:

[0006] A metering cylinder, rotatably arranged on the support and located directly below the batching bin. Both ends of the metering cylinder are through, and a partition is fixed in the middle of the interior of the metering cylinder. On both sides of the partition, there are support plates, and load cells are installed between the support plates and the partition.

[0007] A deflection assembly, which is used to deflect the metering cylinder by 180° so that the two ends of the metering cylinder are alternately upward.

[0008] A limiting assembly, which is used to limit the position after the metering cylinder deflects by 180°.

[0009] Preferably, the deflection assembly includes a servo motor and a second gear. The servo motor is installed on the side wall of the support through a mounting plate, and a first gear is installed at the output end of the servo motor. The second gear is installed at the end of the rotating shaft of the metering cylinder, and the second gear is meshed with the first gear.

[0010] Preferably, the limiting assembly includes:

[0011] The connecting plate is fixed to the outer wall of the measuring cylinder, and the connecting plate is located on the side away from the rotating shaft of the measuring cylinder. Two positioning grooves are symmetrically arranged on the connecting plate;

[0012] At least one through groove is provided on the side wall of the support away from the servo motor. An electric telescopic rod is installed in the through groove, a positioning rod is installed at the end of the electric telescopic rod, and the end of the positioning rod is inserted and matched with the positioning groove.

[0013] Preferably, the partition divides the interior of the measuring cylinder into a first measuring chamber and a second measuring chamber.

[0014] Preferably, a feeding pipe is connected to the bottom end of the batching bin, and a solenoid valve is installed on the feeding pipe.

[0015] Preferably, there are four support legs, and a foot pad is detachably installed at the bottom end of each support leg.

[0016] In the above technical solution, the technical effects and advantages provided by the present utility model are as follows:

[0017] 1. Both ends of the measuring cylinder are open, and two symmetrical measuring chambers are provided. By setting the deflection mechanism, when the measuring chamber below deflects upwards, the measuring chamber above synchronously deflects downwards for pouring, without the need to pour first and then return to the upright position, greatly improving the efficiency. And within the time range of measuring in the upper measuring chamber, it can ensure that the ingredients inside the lower measuring chamber are poured out completely.

[0018] 2. By arranging the limiting component, after the measuring cylinder deflects, the electric telescopic rod in the through groove can be used to drive the positioning rod to move outwards, so that the end of the positioning rod is embedded into the corresponding positioning groove, and then the locking can be completed, ensuring the vertical stability of the measuring cylinder, avoiding the deviation of the measuring cylinder during feeding and measuring, and preventing the spilling of the ingredients.

Detailed implementation manners

[0027] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further introduced in detail below with reference to the accompanying drawings.

[0028] Figure 1 and Figure 2 are both structural schematic diagrams of the present utility model, and in combination with Figures 3 - 5 as shown, the batching bin metering device includes a support 1, an installation frame 2 is fixed at the top of the support 1, a batching bin 3 is installed on the installation frame 2, a blanking pipe 19 is connected to the bottom end of the batching bin 3, a solenoid valve is installed on the blanking pipe 19, the batching bin 3 is used for storing batching, after the solenoid valve is opened, the batching flows down along the blanking pipe 19, support legs 4 are provided at the bottom end of the support 1, there are four support legs 4, and the bottom end of each support leg 4 is detachably installed with a foot pad, and the foot pad is preferably connected by threads and can be replaced after being damaged. In addition, it also includes a measuring cylinder 5, a deflection component and a limit component, which is rotatably arranged on the support 1 and located directly below the batching bin 3. The two ends of the measuring cylinder 5 are through, and a partition board 14 is fixed in the middle of the inside of the measuring cylinder 5. The partition board 14 divides the inside of the measuring cylinder 5 into a first measuring chamber 15 and a second measuring chamber 16. Supporting plates 17 are provided on both sides of the partition board 14, and weighing sensors 18 are installed between the supporting plates 17 and the partition board 14. The deflection component is used to deflect the measuring cylinder 5 by 180° so that the two ends of the measuring cylinder 5 are alternately opened upward to realize the alternate use of the first measuring chamber 15 and the second measuring chamber 16, and the limit component is used to limit the position after the measuring cylinder 5 deflects 180° to prevent deflection.

[0029] Among them, in the detailed implementation manners, refer to Figure 1 and Figure 3As shown in the figure, the deflection assembly includes a servo motor 6 and a second gear 8. The servo motor 6 is installed on the side wall of the support 1 through a mounting plate, and a first gear 7 is installed at the output end of the servo motor 6. The second gear 8 is installed at the end of the rotating shaft of the metering cylinder 5, and the second gear 8 is meshed with the first gear 7.

[0030] Through the above, when in specific use, first make the first metering chamber 15 face vertically upward, then open the solenoid valve. The ingredients in the ingredient bin 3 fall from the feeding pipe 19 into the first metering chamber 15. The weighing sensor 18 real-time feeds back the metering weight. When the required metering weight is reached, the controller (not shown) promptly closes the solenoid valve, then makes the limiting component disengage from the locked and limited state, and then starts the servo motor 6. The output end of the servo motor 6 drives the first gear 7 to rotate, and then drives the meshed second gear 8 to rotate, so that the metering cylinder 5 can rotate. When it rotates until the second metering chamber 16 faces vertically upward, stop deflecting, and then use the limiting component to lock and limit. Subsequently, repeat the feeding and metering operation of the ingredient bin 3. In this way, rapid metering can be effectively achieved, and the metering efficiency can be improved.

[0031] Among them, when the metering chamber below deflects to face upward, the metering chamber above synchronously deflects to face downward for dumping, without the need to dump first and then return to the upright position, which greatly improves the efficiency. And within the time range when the metering chamber above is metering, it can ensure that the ingredients inside the metering chamber below are dumped cleanly.

[0032] The limiting component includes:

[0033] A connecting plate 12, fixed to the outer wall of the metering cylinder 5, and the connecting plate 12 is located on the side away from the rotating shaft of the metering cylinder 5. Two positioning grooves 13 are symmetrically opened on the connecting plate 12;

[0034] At least one through groove 10 is opened on the side wall of the support 1 away from the servo motor 6. An electric telescopic rod 9 is installed in the through groove 10, and a positioning rod 11 is installed at the end of the electric telescopic rod 9. The end of the positioning rod 11 is inserted and fitted with the positioning groove 13.

[0035] Through the above, after the metering cylinder 5 deflects 180°, the electric telescopic rod 9 in the through groove 10 can be used to drive the positioning rod 11 to move outwards, so that the end of the positioning rod 11 is embedded into the corresponding positioning groove 13, and then the locking can be completed, ensuring the vertical stability of the metering cylinder 5, avoiding the metering cylinder 5 from shifting during feeding and metering, and preventing the spilling of ingredients.

[0036] When deflection is required, first use the electric telescopic rod 9 to make the end of the positioning rod 11 disengage from the corresponding positioning groove 13 to achieve the unlocking state.

[0037] Only some exemplary embodiments of the present utility model have been described by way of illustration. Without doubt, for those of ordinary skill in the art, various different ways can be used to modify the described embodiments without departing from the spirit and scope of the present utility model. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present utility model.
