Description

Technical Field

[0001] This utility model relates to the field of weighing device technology, specifically to an electronic explosion-proof weighing device for explosive materials. Background Technology

[0002] The accuracy of weighing explosives directly affects the performance and quality of the final product. During the production of explosives, the proportions of various raw materials need to be strictly controlled to ensure product stability and reliability. Precise weighing ensures that the amount of each raw material used is accurate, thereby producing products that meet quality standards.

[0003] Chinese Patent Publication No. CN221706703U discloses an electronic explosion-proof weighing device for explosive materials, which solves the problem of low efficiency in scanning and marking of each input material during the weighing of raw materials in explosive production using existing barcode scanners. The device includes an explosion-proof electronic scale, an explosion-proof touchscreen, an explosion-proof printer, and an explosion-proof barcode scanner, all electrically connected to a host computer. The explosion-proof barcode scanner is located directly above the explosion-proof electronic scale and is detachably mounted on a support frame. This improves the efficiency of barcode scanning and marking of each input material during the weighing of raw materials in explosive production. When the input material is placed on the explosion-proof electronic scale for weighing, the explosion-proof barcode scanner directly above the scale can scan the barcodes and mark the material via the explosion-proof touchscreen. This process does not require hand-holding the explosion-proof barcode scanner, and its detachable connection to the support frame allows for adjustment of its installation position.

[0004] In the aforementioned prior art, the explosion-proof electronic scale can be used to weigh explosive materials. However, this device is not convenient for weighing powdered explosive materials. If the powdered explosive materials are placed directly on the weighing platform, the electronic explosion-proof scale needs to be picked up and the material poured out when the material is taken out, which can easily cause the material to scatter or fly, resulting in losses. Therefore, an electronic explosion-proof weighing device for explosive materials is needed to meet people's needs. Utility Model Content

[0005] The purpose of this invention is to provide an electronic explosion-proof weighing device for explosive materials.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] This utility model discloses an electronic explosion-proof weighing device for explosive materials, comprising a material box, a material base plate, and a limit stop bar;

[0008] The material box is a cuboid support frame with openings at the top and bottom, and a discharge notch is provided at the bottom of the discharge side wall of the material box.

[0009] The limiting rod is connected above the discharge notch on the discharge side wall of the material box via a vertical shaft; one end of the material base plate is rotatably connected to the discharge side wall of the material box via a horizontal shaft; the material box is placed above the weighing platform of the explosion-proof electronic scale.

[0010] When weighing medicine, when the other end of the material placement base plate is flipped upward to the upper edge of the discharge notch, the limiting stop bar rotates around the vertical axis to near the side wall of the material placement box, limiting the bottom of the free end of the material placement base plate, so that the inner wall of the material placement box and the top of the material placement base plate are filled with weighed medicine.

[0011] When dispensing the medicine, the limiting stop lever rotates around the vertical axis away from the material box, releasing the restriction on the bottom of the free end of the material box base plate. The free end of the material box base plate then rotates downward, allowing the weighed medicine to slide out of the material box from the dispensing notch along the material box base plate.

[0012] The electronic explosion-proof weighing device also includes a push rod connecting seat fixed to the upper surface of the material placement base plate, a push rod slidably connected to the upper surface of the material placement base plate via the push rod connecting seat, and a push plate fixed to the front end of the push rod; the material box has a push rod clearance notch on the discharge side wall, and the rear end of the push rod extends through the push rod clearance notch; when weighing medicine, the push rod is pulled outward so that the rear end face of the push plate is pressed tightly against the discharge side inner wall of the material box; when discharging medicine, the push rod is pushed inward, and the front end face of the push plate pushes the medicine residue left on the upper surface of the material placement base plate out of the material box.

[0013] A push rod bracket is provided on the outer wall opposite the discharge side of the material box. A positioning block is provided at the upper end of the push rod bracket. A positioning groove is correspondingly opened on the side wall of the push rod. When weighing medicine, the positioning groove of the push rod is inserted into the positioning block of the push rod bracket, so that the push rod is positioned with the material bottom plate. When discharging medicine, the push rod rotates synchronously with the material bottom plate, releasing the positioning of the push rod with the material bottom plate.

[0014] Beneficial effects

[0015] This invention relates to an electronic explosion-proof weighing device that, after weighing the medicine, allows the powdered explosive to slide out from the discharge notch along the inclined surface of the bottom plate, so that the weighed powdered explosive can be removed without repeated pouring. This also reduces material loss and scattering during the removal process, thus improving the safety of the weighing operation. Attached Figure Description
