Description

Technical Field

[0001] This utility model relates to the field of weighing instrument technology, and in particular to a weighing instrument with automatic feeding function. Background Technology

[0002] In many fields such as industrial production, agricultural processing, and logistics warehousing, weighing instruments are the core equipment for achieving accurate material measurement. Their performance is directly related to product quality control, production cost accounting, and production process optimization. The traditional weighing instrument loading process has long relied on manual operation mode. Operators need to manually move materials to the weighing instrument's supporting device. This process has many insurmountable drawbacks.

[0003] However, existing weighing instruments mainly rely on manual feeding. Under continuous operation, the operator's physical strength and energy decline, resulting in reduced hand stability. This causes the feeding rhythm to change from a stable and uniform speed to fluctuating between fast and slow, with sudden large fluctuations in the feeding amount. This leads to inaccurate control of the feeding amount, easily resulting in overfeeding or underfeeding. This not only increases the fatigue of the operator but also affects the accuracy of the measurement results. Utility Model Content

It effectively avoids operational errors caused by frequent material additions and manual control of material feeding in traditional manual feeding, as well as human fatigue caused by long-term repetitive operations.

Detailed Implementation

[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] Example 1: Refer to Figure 1 - Figure 4 As shown: A weighing instrument with automatic feeding function, including a base 1;

[0027] The conveyor body 2 is located on top of the base 1;

[0028] Automatic feeding component 3 is set on top of base 1;

[0029] Metering component 4 is installed on the outer surface of automatic feeding component 3;

[0030] The automatic feeding assembly 3 includes a bracket 301, a storage bin 305, and an electric telescopic rod 306. A slot 302 is provided on the top of the bracket 301, and a discharge bin 303 is fixedly installed at the bottom of the bracket 301. A metering sensor 304 is fixedly installed inside the discharge bin 303. A first rack 307 is fixedly installed at the telescopic end of the electric telescopic rod 306. A set of gears 308 are meshed with the outer surface of the first rack 307, and a second rack 309 is meshed with the outer surface of each set of gears 308. A set of gears 308 is fixedly connected to the outer surface of each set of gears 308. A baffle plate 310 is slidably connected to the inner wall of the storage bin 305 on its outer surface. A set of limiting plates 311 are symmetrically fixedly connected to the top of the bracket 301. A limiting rod 312 is rotatably connected to the inner wall of the limiting plates 311. The outer surface of the limiting rod 312 is slidably connected to the inner wall of the baffle plate 310. The bottom of the storage bin 305 and the electric telescopic rod 306 are fixedly installed to the top of the bracket 301. The bottom of a set of gears 308 is rotatably connected to the top of the bracket 301. The bottom of the bracket 301 is fixedly connected to the top of the base 1.

[0031] In this embodiment, during use, the conveyor body 2 is first started to enter standby mode, and the conveyor belt begins to pre-run at a uniform speed, waiting to receive materials. Then, the operator inputs the target weight of the required material in grams through the control system, causing the equipment to enter the automatic feeding preparation stage. At the same time, after receiving the start signal, the external controller drives the electric telescopic rod 306 to extend from the initial retracted state. Its telescopic end drives the first rack 307 to move forward along the horizontal guide rail. The teeth of the first rack 307 precisely mesh with the gears 308 on both sides. When the rack moves forward, it synchronously drives the gears 308 on both sides to rotate. During the rotation of the gears 308, the teeth mesh with the second rack 309 along the horizontal guide rail. The second rack 309 moves laterally to both sides, connecting with the baffle plate 310. Therefore, as the second rack 309 expands to both sides, the baffle plate 310 gradually opens from its closed state, opening the channel between the storage bin 305 and the discharge bin 303. At this time, the granular or powdered material pre-stored in the storage bin 305 falls orderly into the discharge bin 303 below under gravity through the slot 302 above the support 301. The metering sensor 304 installed inside the discharge bin 303 collects the cumulative weight of the material in the discharge bin 303 in real time and continuously transmits the weight data to the control system in the form of an electrical signal. When the material reaches the target weight preset by the control system, the metering sensor... 304 sends a signal to the external controller, which immediately controls the electric telescopic rod 306 to rotate in the opposite direction. Its telescopic end drives the first rack 307 to retract along the horizontal guide rail, and the gears 308 on both sides rotate accordingly. The second rack 309 returns to the center, and the baffle plate 310 gradually closes from the open state until it completely blocks the outlet of the storage bin 305, stopping material discharge. During the entire opening and closing process of the baffle plate 310, the limiting rod 312 inside the limiting plate 311 cooperates with the limiting groove inside the baffle plate 310. When the baffle plate 310 moves, the limiting rod 312 is always embedded in the groove and slides, limiting the horizontal displacement of the baffle plate 310 and preventing the baffle plate 310 from shaking. To prevent material leakage or measurement deviation, after the baffle plate 310 is fully closed, the material that has been measured in the discharge bin 303 falls onto the conveyor belt of the conveyor body 2 below through the conical discharge port at the bottom of the discharge bin 303 under the action of gravity. The conveyor belt of the conveyor body 2 runs at a uniform speed, smoothly transporting the material to the next process, completing a single automatic feeding and measurement process. Under the action of the automatic feeding component 3, the fully automatic feeding and measurement operation of materials can be realized, effectively avoiding the operational errors caused by frequent feeding and manual control of the feeding amount during traditional manual feeding, as well as the problem of human fatigue caused by long-term repetitive work. Thus, it not only reduces human fatigue, but also ensures the accuracy of the measurement results.

[0032] Example 2: According to Figure 1 - Figure 4As shown: The metering component 4 includes an alarm 401, a feed inlet 402 and an infrared sensor 404. The outer surface of the alarm 401 is fixedly installed on the outer surface of the storage bin 305. The bottom of the feed inlet 402 is fixedly connected to the top of the storage bin 305. A threaded cap 403 is threadedly connected to the outside of the feed inlet 402. The outer surface of the infrared sensor 404 is fixedly installed on the inner wall of the storage bin 305.

[0033] In this embodiment, before using this device, material preparation work needs to be completed. First, unscrew the threaded cap 403 on the top of the storage bin 305, and add material into the storage bin 305 through the feed port 402. After adding to the preset liquid level or reasonable capacity, close the threaded cap 403 to ensure that the storage bin 305 is well sealed. As the automatic feeding component 3 continues to operate and supply material, the material in the storage bin 305 gradually decreases due to continuous discharge. At this time, the infrared sensor 404 installed inside the storage bin 305 monitors the material height in the bin in real time. When the material liquid level drops to the monitoring threshold of the infrared sensor 404, the sensor immediately sends a low material level signal to the external controller. The external controller then activates the alarm 401, prompting the staff to replenish the material in time through continuous sound or flashing light, so as to avoid interruption of feeding due to insufficient storage. Under the precise action of the metering component 4, the entire process of material from discharge to weighing can be automated, thereby improving the stability of material metering and the continuity of production operations, and reducing the loss of production efficiency caused by untimely manual replenishment or metering deviation.

[0034] Working principle: Unscrew the threaded cap 403 on the top of the storage hopper 305, add material to the hopper through the feed inlet 402 to the preset liquid level, and close the threaded cap 403 to ensure a seal. As the automatic feeding component 3 operates, the material in the storage hopper 305 gradually decreases. The inner infrared sensor 404 monitors the material level in real time. When the material level drops to the monitoring threshold, the sensor sends a signal to the external controller, triggering the alarm 401 to sound an alarm to prompt for replenishment and avoid interruption of the feeding. In use, first start the conveyor body 2 to enter standby mode. The operator inputs the target measurement weight in grams through the control system, and the equipment enters the automatic feeding preparation stage. The external controller drives the electric telescopic rod 306 to extend. The first rack 307 moves forward along the guide rail and meshes with the gears 308 on both sides, driving the gears 308 to rotate and linking the second rack 309 to move horizontally to both sides, causing the baffle plate 310 to open. The channel between the storage bin 305 and the discharge bin 303 is opened, and the material falls into the discharge bin 303 through the slot 302. The internal metering sensor 304 monitors in real time and transmits the data to the control system. After the target is reached, the sensor sends a signal to retract the electric telescopic rod 306 and close the baffle plate 310. During opening and closing, the limit rod 312 in the limit plate 311 is embedded in the slide groove of the baffle plate 310 to limit the material and prevent leakage deviation. Finally, the material falls into the conveyor through the conical discharge port and is conveyed to the next process, completing a single metering.

[0035] By following the steps outlined above, you can use the weighing instrument with automatic feeding function.
