Description

Technical Field

[0001] This utility model relates to the field of material conveying and weighing technology, and in particular to an automatic weighing and feeding device. Background Technology

[0002] Automatic weighing and feeding devices are widely used material conveying and metering equipment in industries such as chemical, food, and pharmaceutical. They are mainly used to achieve automatic weighing and quantitative feeding of solid or granular materials. These devices typically achieve continuous material supply and accurate metering through the cooperation of support structures, weighing units, and conveying mechanisms, playing an important role in improving production efficiency and ensuring batching accuracy.

[0003] Some automatic weighing and feeding devices still have certain limitations in actual use. For example, after completing one weighing and discharging of material, it is often necessary to wait for the weighing unit to reset and receive material again, resulting in an intermittent weighing process and affecting the efficiency of continuous production. In addition, traditional devices have complex structures and slow responses when switching material channels, making it difficult to achieve high-speed, high-frequency alternating weighing and feeding, which can easily cause production interruptions or a decrease in weighing accuracy. Utility Model Content

[0005] The technical solution adopted by this utility model is as follows: an automatic weighing and feeding device, including a support frame, a support platform fixedly installed on the top of the support frame, a top plate provided above the support platform and the support platform and the top plate fixedly connected by multiple fixed columns, a movable frame slidably connected between the support platform and the top plate, a feeding pipe fixedly connected at the center of the top of the top plate, two vertically arranged discharge channels passing through the movable frame, a weighing device embedded in the middle of the support platform and the top of the weighing device being flush with the top of the support platform, and a discharge box fixedly connected at the bottom of the support platform and a discharge pipe connected at the bottom of the discharge box.

[0006] As a further improvement of this utility model, the number of fixed columns is at least six and they are symmetrically distributed at the edges of the support platform and the top plate.

[0007] As a further improvement of this utility model, two fixed seats are fixedly installed on the top of the support platform. Each of the two fixed seats is connected to a horizontally arranged electric telescopic rod, and the two electric telescopic rods are respectively located on both sides of the movable frame. The movable ends of the two electric telescopic rods are connected by a connecting rod, and the connecting rod is connected to one end of the movable frame by a connecting seat.

[0008] As a further improvement of this utility model, multiple auxiliary wheels for assisting the sliding of the movable frame are fixedly installed on both sides of the support platform.

[0009] As a further improvement of this utility model, the support platform is provided with discharge openings on both sides of the weighing device.

[0010] As a further improvement of this utility model, the distance between the center of the discharge opening and the center of the weighing device is equal to the distance between the centers of the two discharge channels.

[0011] The beneficial effects of this utility model are as follows: By setting up a double feeding channel and a movable frame that can move laterally, and with symmetrical discharge openings, this utility model allows the other channel to unload material while one channel is weighing, thus realizing uninterrupted continuous weighing operation, which greatly improves production efficiency and weighing accuracy.

[0016] To make the technical problems to be solved, the technical solutions, and the beneficial effects of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0017] This utility model provides the following: Figure 1-4 An automatic weighing and feeding device is shown, comprising a support frame 1, characterized in that: a support platform 2 is fixedly installed on the top of the support frame 1, a top plate 3 is provided above the support platform 2 and the support platform 2 and the top plate 3 are fixedly connected by multiple fixed columns 4, a movable frame 5 is slidably connected between the support platform 2 and the top plate 3, a feeding pipe 6 is fixedly connected at the center of the top of the top of the top plate 3, two vertically arranged discharge channels 7 are provided inside the movable frame 5, a weighing device 8 is embedded in the middle of the support platform 2 and the top of the weighing device 8 is flush with the top of the support platform 2, and a discharge box 9 is fixedly connected to the bottom of the support platform 2 and a discharge pipe 10 is connected to the bottom of the discharge box 9.

[0018] like Figure 1 As shown, in this utility model, the number of fixed columns 4 is at least six and they are symmetrically distributed at the edges of the support platform 2 and the top plate 3. The six fixed columns 4 can provide stable support for the top plate 3, ensure the connection strength between the top plate 3 and the support platform 2, and prevent the structure from loosening due to vibration and other factors during operation, thereby ensuring the smooth sliding of the movable frame 5 and the overall operational stability of the device.

[0019] like Figure 2-4 As shown, in this utility model, two fixed seats 11 are fixedly installed on the top of the support platform 2. Each fixed seat 11 is connected to a horizontally arranged electric telescopic rod 12, and the two electric telescopic rods 12 are located on both sides of the movable frame 5. The movable ends of the two electric telescopic rods 12 are connected by a connecting rod 13, and the connecting rod 13 is connected to one end of the movable frame 5 via a connecting seat 14. When the electric telescopic rod 12 extends or retracts, it can drive the movable frame 5 to slide back and forth along the length of the support platform 2 between the support platform 2 and the top plate 3 via the connecting rod 13 and the connecting seat 14, thereby realizing the switching of the positions of the two feeding channels 7.

[0020] like Figure 1 and Figure 2 As shown, in this utility model, multiple auxiliary wheels 15 are fixedly installed on both sides of the movable frame 5 on the support platform 2 to assist the sliding of the movable frame 5, which improves the smoothness of the sliding of the movable frame 5. The number of auxiliary wheels 15 on each side is at least four and they are distributed at intervals along the length of the support platform 2. The auxiliary wheels 15 are fixedly installed on the top of the support platform 2 through wheel seats. The wheel surface of the auxiliary wheels 15 is in contact with the side of the movable frame 5, which can guide and support the sliding of the movable frame 5 and reduce the friction when the movable frame 5 slides.

[0021] like Figure 2-4As shown, in this utility model, the support platform 2 has discharge openings 16 on both sides of the weighing device 8. The distance between the center of the discharge opening 16 and the center of the weighing device 8 is equal to the distance between the centers of the two feeding channels 7. When the movable frame 5 slides, one of the feeding channels 7 is directly above the weighing device 8 for feeding material into the weighing device 8 for weighing, while the other feeding channel 7 is directly above one of the discharge openings 16 for discharging material into the discharge box 9 below through the discharge opening 16.

[0022] Working Principle: In practical implementation, the material is first fed into the device through the feed pipe 6. After the material enters the top plate 3, since the movable frame 5 is in its initial position, one of the discharge channels 7 in the movable frame 5 is directly below the feed pipe 6. The material falls into the weighing device 8 on the support platform 2 through the discharge channel 7, and the weighing device 8 weighs the material. When the material on the weighing device 8 reaches the set weight, the control system controls the electric telescopic rod 12 to move. The movable end of the electric telescopic rod 12 extends or retracts, and through the connecting rod 13 and the connecting seat 14, it drives the movable frame 5 to slide, so that the other discharge channel 7 that has not yet discharged material moves to directly below the feed pipe 6 and begins to feed the next batch of material into the weighing device 8 for weighing. Meanwhile, the discharge channel 7 that has completed the discharge and weighing moves to directly above one of the discharge openings 16. The material remaining in the discharge channel 7 or a small amount of material that may be attached later can fall into the discharge box 9 below through the discharge opening 16 and be discharged through the discharge pipe 10. By alternating the operation of the two feeding channels 7, one channel 7 can feed material to the weighing device 8 for weighing while the other channel 7 can prepare for or discharge material, achieving a continuous weighing and feeding process and effectively improving work efficiency. Meanwhile, the auxiliary wheels 15 ensure the smooth sliding of the movable frame 5, and the multiple fixed columns 4 ensure the stability of the overall structure of the device, making the device more reliable and effectively guaranteeing weighing accuracy.

[0023] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
