Description

Technical Field

[0001] The utility model relates to the technical field of weighing equipment, in particular to an electronic belt scale. Background Technique

[0002] The working principle of an electronic belt scale is to install a weighing frame under the upper belt of a belt conveyor. When there is material passing through the belt conveyor, the weight of the material will generate a certain pressure, which acts on the weighing sensor in the belt scale frame through the idler bracket on the weighing frame, generating a voltage signal corresponding to the weight of the material per unit length of the belt conveyor. At the same time, the speed sensor on the belt conveyor measures a signal corresponding to the running speed of the belt. The weighing and metering controller calculates these two signals through integral operation, so as to obtain the instantaneous flow rate and cumulative weight value of the material passing through the belt conveyor.

[0003] Problems existing in current electronic belt scales: Existing electronic belt scales mainly include types such as double-lever four-idler scales and fully suspended four-idler scales. Their scale frames are relatively large, inconvenient for on-site installation, and require multiple people to work together to solve. At the same time, the structure is complex and requires frequent maintenance to avoid affecting the detection accuracy; in addition, the material accumulated on the scale frame will affect the accuracy of detection.

[0004] Therefore, it is very necessary to propose an electronic belt scale to solve the above problems. Content of the Utility Model

Detailed implementation manners

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0027] Please refer to Figures 1-5 As shown, an electronic belt scale includes a bottom plate 10. On both sides above the bottom plate 10, fixed plates 6 and floating plates 9 are arranged oppositely. The fixed plate 6 and the floating plate 9 are parallel to each other and fixedly connected by a weighing sensor 7. The fixed plate 6 is fixedly connected to the bottom plate 10. The floating plate 9 is vertically arranged above the bottom plate 10. There is a floating gap between the floating plate 9 and the bottom plate 10. Connecting plates 11 are fixedly connected to both ends of the bottom plate 10. Preferably, both ends of the fixed plate 6 are respectively fixedly connected to the two connecting plates 11. At both ends of the top of the floating plate 9, support plates 5 are fixedly connected. At the top end of the support plate 5, a roller frame 15 is fixedly connected. A roller 1 is installed on the roller frame 15.

[0028] During use, it is fixed to the belt conveyor support by bolts. When the roller 1 bears the weight, it is transmitted to the weighing sensor 7 through the floating plate 9. The instantaneous weight of the material is detected by the weighing sensor 7. Weighing is performed in this way. It has no moving parts, so it does not need to be frequently maintained, and only needs to be regularly calibrated.

[0029] By arranging the vertically arranged floating plate 9, scattered materials can be prevented from falling onto the floating plate 9, affecting the accuracy of weighing. The bottom plate 10 and the fixed plate 6 form an L-shaped frame body. Using the L-shaped frame body can further improve its structural strength.

[0030] Among them, the weighing sensor 7 adopts a cantilever beam weighing sensor.

[0031] In some embodiments, in order to facilitate the fixation of the roller frame 15, the roller frame 15 includes a column 2 and a cross beam 4. The cross beam 4 is fixedly connected to the support plate 5 through a hoop member 3. The column 2 is fixedly connected to the cross beam 4. Preferably, the hoop member 3 acts on the column 2 to limit the length direction of the cross beam 4, preventing the cross beam 4 from moving in its length direction.

[0032] Specifically, the cross section of the cross beam 4 is triangular. By arranging the triangular cross beam 4, scattered materials can be prevented from accumulating on the cross beam 4, affecting the weighing accuracy.

[0033] Specifically, there is a floating gap between the cross beam 4 and the connecting plate 11, preventing the lower end surface of the cross beam 4 from falling onto the connecting plate 11, affecting the weighing.

[0034] In some embodiments, a protective housing 12 is sleeved outside the load cell 7, and the protective housing 12 is fixedly connected to the fixing plate 6. By providing the protective housing 12, the load cell 7 can be protected. It should be noted that neither the load cell 7 nor the floating plate 9 can contact the protective housing 12 to avoid affecting the weighing accuracy.

[0035] In some embodiments, to improve the structural strength, the support plate 5 is fixedly connected to the floating plate 9 through a support member 8, and the support member 8 is fixedly connected to the side of the floating plate 9 close to the fixing plate 6.

[0036] To facilitate regular calibration thereof, a weight hanger 14 is fixedly connected to the side of the floating plate 9 away from the fixing plate 6.

[0037] During static calibration, weights are placed on the weight hanger 14, and the measured value of the load cell 7 is compared with the actual weight of the weights, and it is calibrated according to the error.

[0038] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
