Description

Technical Field

[0001] The utility model belongs to the technical field of belt scales, and in particular relates to an automatic material-pushing electronic belt scale. Background Art

[0002] An electronic belt scale is an automatic weighing instrument that continuously weighs bulk materials on a conveyor belt without the need to subdivide the mass or interrupt the movement of the conveyor belt. Existing belt scales are usually placed under the conveyor belt through a base to weigh the materials on the conveyor belt while the conveyor belt is moving. However, when materials are sometimes uploaded to the conveyor belt, uneven loading can easily cause a large amount of material to accumulate in one place. When the material weighed at a single time is too heavy, it can easily cause the belt scale to produce excessive errors during weighing, affecting the overall material weighing data. Utility Model Content

[0003] In order to solve the above-mentioned deficiencies in the prior art, the purpose of the utility model is to provide an automatic material pushing electronic belt scale to solve the problems mentioned in the background technology.

[0004] The technical solution adopted by this automatic material pushing electronic belt scale to solve its technical problems is:

[0005] An automatic material pushing electronic belt scale is provided, comprising a conveyor belt, wherein a bottom plate is provided below the conveyor belt, a plurality of support columns are fixedly mounted on the bottom plate, an electric slide rail is provided above the conveyor belt, the electric slide rail is fixedly mounted on the support columns, a material pushing plate is fixedly mounted on the slider of the electric slide rail, transparent tubes are respectively provided on the front and rear sides of the material pushing plate, brackets are fixedly mounted on the front and rear ends of the transparent tube, the brackets are respectively fixedly mounted on the material pushing plate, a laser transmitter is fixedly mounted in one of the transparent tubes, a laser receiver is fixedly mounted in the other transparent tube corresponding to the laser transmitter, and a belt scale is provided below the conveyor belt on one side of the bottom plate.

[0006] Furthermore, the cross section of the conveyor belt is an inverted trapezoid.

[0013] 1. An automatic pushing electronic belt scale according to an example of the utility model, when using this device, materials are conveyed to the conveyor belt and are weighed when passing through the belt scale.

When the laser receiver cannot receive the laser emitted by the laser transmitter, the electric slide rail is controlled to move, and the push plate pushes the excess material forward to evenly distribute the material on the conveyor belt until the laser receiver receives the laser again, and the electric slide rail is controlled to reset. Through this device, when there is too much material locally on the conveyor belt, the material on the conveyor belt can be evenly distributed by moving the push plate, which can avoid excessive errors caused by the heavy material processed at a single time on the belt scale.

[0014] 2. An automatic material-pushing electronic belt scale in the example of the utility model can make the materials on the conveyor belt converge to the middle through the inverted trapezoidal conveyor belt, thereby avoiding material spillage during use.

[0015] 3. An automatic material pushing electronic belt scale in the example of the utility model can better push materials through the contact and cooperation between the side wall of the pushing plate and the side of the conveyor belt. At the same time, through the arc-shaped groove, it can ensure the passage of materials while conveniently gathering the materials to the middle of the conveyor belt.

[0016] 4. An automatic material pushing electronic belt scale in the example of the utility model can protect the materials during the material pushing process through the guard plate to prevent the materials from falling from both sides of the conveyor belt during the material pushing process.

[0017] 5. An automatic material pushing electronic belt scale according to an example of the utility model, when in use, when the slider of the electric slide rail drives the pushing plate to move to the end of the stroke, the contact block contacts the contact switch, and the alarm sounds an alarm to remind the user to temporarily reduce the output of materials and wait for the weighing of the materials on the current conveyor belt to be completed before releasing the materials.

[0018] 6. The buzzer alarm of the automatic material pushing electronic belt scale in the utility model has the characteristic of intuitive alarm effect and can quickly remind the user through buzzing.

[0019] 7. An automatic material-pushing electronic belt scale in the example of the utility model can accurately control the forward and backward movement of the electric slide rail according to the electrical signals transmitted by the laser transmitter and the laser receiver through a controller.
