Description

Technical Field

[0001] This utility model belongs to the technical field of belt scales and relates to an automatic batching belt scale. Background Technology

[0002] Belt scales, as crucial equipment for material metering and conveying in industrial production, are widely used in various industries such as chemical, mining, metallurgy, and building materials. Their basic principle involves using load cells to measure the real-time weight of material on a continuously running belt, combined with a speed sensor to determine the belt speed, thereby calculating the flow rate and total quantity of material per unit time. This technology provides precise material proportioning control for automated production, significantly improving production efficiency and reducing human error.

[0003] Traditional belt scale designs primarily focus on achieving more accurate metering and more stable material conveying performance. However, with the continuous development of industrial production and technological advancements, the requirements for belt scales are constantly increasing. Especially for materials with poor flowability or those prone to airborne particles, traditional straight conveyor belt structures often fall short. To better adapt to the conveying needs of these special materials, several improved design solutions have emerged in existing technologies.

[0004] On the one hand, to increase the conveyor belt's carrying capacity and prevent material slippage during transport, some belt scales design the conveyor belt with a V-shaped structure, using the higher edges on both sides to limit the material's movement range. On the other hand, some designs choose to install corrugated skirts on both sides of the conveyor belt to improve material carrying capacity and stability. While these two methods improve the stability and efficiency of material conveying to some extent, they also bring new problems: both the V-shaped structure and the corrugated skirts increase the belt's bending stress or exacerbate localized wear, thus shortening the belt's service life. Furthermore, these structural designs can easily cause material to adhere to the belt, affecting not only the belt scale's accuracy but also increasing the workload of cleaning and maintenance. Utility Model Content

[0005] The purpose of this invention is to provide an automatic batching belt scale that can effectively improve the stability of material conveying, extend the service life of the belt, reduce material adhesion on the conveyor belt surface, and improve the accuracy of the belt scale.

[0006] To solve the above-mentioned technical problems, this utility model provides an automatic batching belt scale, including a base frame. A conveyor housing with openings on the upper side and both ends is arranged on the upper part of the base frame. Multiple weighing sensors are arranged between the lower end of the conveyor housing and the upper end of the base frame. Rollers are rotatably connected to both ends of the conveyor housing. A conveyor belt with two rollers is movably arranged inside the conveyor housing. Both sides of the conveyor belt are provided with outwardly flared skirt belts. Each roller has a frustum support roller at both ends that cooperates with the corresponding skirt belt. A drive motor for driving the rollers to rotate is installed outside the conveyor housing. A cleaning roller brush is rotatably connected to one end of the conveyor housing below the conveyor belt. The cleaning roller brush moves synchronously and in the same direction as the conveyor belt. Both ends of the cleaning roller brush are inclined surfaces that cooperate with the corresponding skirt belts. The cleaning roller brush is in contact with the surface of the conveyor belt and each skirt belt.

[0007] By adopting the above technical solution, during automatic batching, materials are added from one end of the conveyor belt. The drive motor drives the conveyor belt to transport the materials forward. During the process, four weighing sensors work together to detect the weight on the conveyor housing to achieve quantitative batching based on weight. The skirt belt prevents materials from slipping off during the process. After the materials are output from one end of the conveyor belt, the cleaning roller brush moves synchronously and in the same direction as the conveyor belt, which can brush off the materials attached to the surface of the conveyor belt and the skirt belt and let them fall forward into the batching area. This prevents the materials attached to the belt from affecting the accuracy of the belt scale, and at the same time prevents the materials from falling into the interior of the conveyor housing with the conveyor belt.

[0008] The present invention is further configured such that a plurality of support seats corresponding one-to-one with the weighing sensors are provided at the lower end of the conveyor housing, and each weighing sensor is disposed between the base frame and the corresponding support seat.

[0009] The present invention is further configured such that multiple support rollers arranged side by side and in contact with the upper side of the conveyor belt are rotatably connected inside the conveyor housing.

[0010] The present invention is further configured such that rotating connecting strips are provided inward on both sides of the conveyor housing, and each support roller is rotatably connected between the two rotating connecting strips.

[0011] The present invention is further configured such that one end of each roller shaft extends out of the conveyor housing and is provided with a driven pulley, the power output shaft of the drive motor is connected to a drive pulley, and the drive pulley and one of the driven pulleys are driven by a belt.

[0012] The present invention is further configured such that one end of the cleaning roller brush extends out of the conveyor housing and is provided with a transmission pulley, and the transmission pulley and the adjacent driven pulley are driven by a belt.

[0013] The present invention is further configured such that a guide plate is provided at one end of the conveyor housing, which is located outward and downward from the cleaning roller brush.

[0014] The present invention is further provided that the surface of the cleaning roller brush is provided with nylon bristles.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] Firstly, this utility model has an integrated skirt belt on both sides of the conveyor belt. During the material conveying process, the belt will not experience large bending stress, reducing belt wear and thus extending the belt's service life.

[0017] Secondly, this utility model has a cleaning roller brush that moves synchronously and in the same direction at one end of the conveyor belt. The cleaning roller brush can brush off the material attached to the surface of the belt and let it fall forward into the batching area, so as to avoid the material attached to the belt affecting the accuracy of the belt scale, and at the same time prevent the material from falling into the inside of the conveyor housing along with the conveyor belt.

[0022] The automatic batching belt scale of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of this utility model will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model. The same or similar reference numerals in the drawings represent the same or similar parts.

[0023] Example, refer to Figure 1-3An automatic batching belt scale includes a base frame 1. A conveyor housing 2, open on the top and both ends, is mounted above the base frame 1. Four evenly distributed support seats 3 are arranged in an array at the lower end of the conveyor housing 2. A weighing sensor 4 is installed between each support seat 3 and the base frame 1. The four weighing sensors 4 work together to detect the weight on the conveyor housing 2. A roller shaft 5 is rotatably connected to both ends inside the conveyor housing 2. A drive motor 6 is installed on the lower rear end of the conveyor housing 2 to drive the roller shaft 5. One end of each roller shaft 5 extends out of the conveyor housing 2 and is equipped with a driven pulley 7. The power output shaft of the drive motor 6 is connected to a drive pulley 8, and the drive pulley 8 and the driven pulley 7 at the rear end are driven by a belt.

[0024] A conveyor belt 9 with two outer rollers 5 is movably installed inside the conveyor housing 2. A rotating connecting strip 10 is installed inwards on both sides of the conveyor housing 2. Multiple support rollers 11, arranged side-by-side and in contact with the upper side of the conveyor belt 9, are rotatably connected between the two rotating connecting strips 10 to prevent the conveyor belt from sinking due to excessive material weight. A flared skirt belt 12 is installed outwards on both sides of the conveyor belt 9. The two skirt belts 12 are integrated with the conveyor belt 9. Each roller 5 has a frustum support roller 13 at both ends that cooperates with the corresponding skirt belt 12. The frustum support roller 13 provides support and transmission for the skirt belt 12.

[0025] A cleaning roller brush 14 is rotatably connected to one end of the conveyor housing 2 below the conveyor belt 9. One end of the cleaning roller brush 14 extends out of the conveyor housing 2 and is provided with a drive pulley 15. The drive pulley 15 and the driven pulley 7 at the front end are driven by a belt, so that the cleaning roller brush 14 moves synchronously and in the same direction as the conveyor belt 9. A guide plate 16 is provided at one end of the conveyor housing 2 below the cleaning roller brush 14 and downward, so that the material falling from the cleaning roller brush 14 will also fall onto the guide plate 16 and slide forward, preventing the material from falling into the interior of the conveyor housing 2. Both ends of the cleaning roller brush 14 are inclined surfaces that cooperate with the corresponding skirt belts 12. The cleaning roller brush 14 is in contact with the surface of the conveyor belt 9 and each skirt belt 12. The surface of the cleaning roller brush 14 is provided with nylon bristles.

[0026] Working principle: During automatic batching, materials are added from one end of the conveyor belt 9. The drive motor 6 drives the conveyor belt 9 to transport the materials forward. During the process, four weighing sensors 4 work together to detect the weight on the conveyor housing 2 to achieve quantitative batching based on weight. The skirt belt 12 prevents materials from slipping. After the materials are output from one end of the conveyor belt 9, the cleaning roller brush 14 moves synchronously and in the same direction as the conveyor belt 9, which can brush off the materials attached to the surface of the conveyor belt 9 and the skirt belt 12 and drop them forward into the batching area. This prevents the materials attached to the belt from affecting the accuracy of the belt scale and also prevents the materials from falling into the interior of the conveyor housing 2 with the conveyor belt 9.

[0027] It should also be noted that all terms such as "set up" and similar descriptive words in this application (especially the specification) indicate that two structures have or exist a connection relationship. However, the specific means by which the two are connected are not limited in detail, and are usually conventional connection methods. That is, the means should be understood as prior art and do not need to be elaborated. For example, "m is set up with n" only indicates that structure m has structure n, and whether the two are connected by welding, riveting, adhesive, or integral molding is within the scope of protection of this application. Similarly, "x is rotatably set up with y" only indicates that y and x can rotate relative to each other, and whether the two are connected by a bearing, or whether y directly passes through x and is rotatably connected to x, or other feasible methods, are all within the scope of protection of this application.
