Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of load-bearing equipment, and in particular to an electronic belt scale. Background Technology
[0002] Electronic belt scales are dynamic and continuous metering devices specifically designed for bulk materials, and are widely used in industries such as mining, metallurgy, power, chemical, and building materials.
[0003] Existing electronic belt scales are typically exposed to dust and material residue environments for extended periods. Dust adheres to the measuring rollers, and when it enters the rollers, it can easily cause them to jam, resulting in sluggish rotation. During material transport, because the belt overlaps with the load-bearing rollers, it is prone to belt misalignment, leading to uneven loading and premature wear of the measuring rollers. Therefore, regular maintenance of the measuring rollers is necessary to ensure the accuracy of the electronic belt scale's measurements.
[0004] In the process of implementing this embodiment, the inventors discovered at least the following problems:
[0005] Existing electronic belt scales require frequent routine maintenance when measuring idler rollers. Utility Model Content
[0006] The purpose of this invention is to provide an electronic belt scale that solves the technical problem that existing electronic belt scales require frequent daily maintenance when measuring idler rollers.
[0007] Utility model solution:
[0008] This utility model provides an electronic belt scale, including a belt, a support frame, a pressure measuring element, a measuring roller assembly, and a blowing assembly. The pressure measuring element is mounted on the support frame. The measuring roller assembly includes a limiting seat, an inclined roller, and a horizontal roller. The limiting seat is drively connected to the pressure measuring element. The inclined roller and the horizontal roller are pivotally connected to the limiting seat, and the belt overlaps the inclined roller and the horizontal roller. The limiting seat is pivotally connected to a limiting roller, which is located at both ends of the limiting seat. The blowing assembly includes a support table, a blower, a bellows, and a blowing component. The support table is located below the support frame. The blower is mounted on the support table. The bellows is mounted on the support table and connected to the blower. The blowing component is mounted between the belt and the support frame and connected to the bellows.
[0009] Furthermore, the limiting roller is connected to a limiting shaft, the limiting seat is provided with a keyway, and the limiting shaft is disposed in the keyway.
[0010] Furthermore, the limiting shaft is threaded with a fixing nut, which abuts against the limiting seat.
[0011] Furthermore, the limiting seat is connected to a limiting post, and the limiting post is connected to a limiting plate.
[0012] Furthermore, the limiting post passes through the limiting seat and is connected to the limiting cap. The limiting post is fitted with a spring, which is located between the limiting plate and the limiting seat.
[0013] Furthermore, each of the limiting plates is connected to two of the limiting posts.
[0014] Furthermore, the belt has an arc-shaped edge.
[0015] Furthermore, the belt is provided with a fluoropolymer coating.
[0016] Furthermore, the blower includes a blower tube and a plurality of blower pipes; the blower tube is connected to the air box, and the plurality of blower pipes are connected to the blower tube.
[0017] Furthermore, several of the aforementioned blower tubes are evenly arranged on both sides of the blower tube.
[0018] Beneficial effects:
[0019] This invention provides an electronic belt scale. During use, the blower is activated, blowing air into the air box. The air box distributes the airflow to various blowing components, which in turn blow air onto the inclined and horizontal rollers, preventing dust from falling into them. When the belt deviates, the limit roller on the limit seat abuts against the belt, correcting its position and ensuring it does not shift. This type of electronic belt scale significantly reduces the damage rate of the measuring rollers, thereby reducing the frequency of routine maintenance. Attached Figure Description
