An automatic weighing and boxing device for powdery explosives

Abstract

The invention discloses an automatic weighing and boxing device for powder blasting supplies. The automatic weighing and boxing device is composed of a roller conveying line, a feeding and weighing device, a vibration platform, an auxiliary device and a finished product packaging table. Part of the roller conveying line and the finished product packaging table are installed outside a semi-closed workshop. The roller conveying line is formed by sequentially connecting a plurality of roller conveyors in the conveying sequence. An explosion-proof motor and power chain wheel type rollers are adopted by the roller conveyors, and the roller conveyors are subjected to dust-proof treatment, so that automatic conveying of products is achieved. Weighing of materials and automatic filling of the materials are completed by the feeding and weighing device. The vibration platform is used for jolt-ramming of the materials, the number of gaps between the materials is reduced, and the materials are prevented from being piled up. The auxiliary device is used for pushing material boxes onto the vibration platform and pushing the material boxes off the vibration platform after the material boxes are filled with the materials. The finished product packaging table is used for product packaging. The automatic weighing and boxing device is provided with pneumatic elements, the explosion-proof structure design is adopted, and unmanned operation is achieved; and the automatic weighing and boxing device has the characteristics of being simple in structure, high in weighing precision and convenient and fast to operate.

Description

technical field [0001] The invention relates to the technical field of mechanical design and automatic control, in particular to an automatic weighing and boxing device for powdered explosives. Background technique [0002] In the patent 201420397915.6, "an automatic weighing and discharging system for bulk materials" is proposed. The system includes a hopper, a feeding device, a weighing device, a weighing bracket, a discharging device, a lifting device for a discharging cup and a frame. . The system can realize automatic feeding and automatic weighing, and there is no mechanical contact interference during the weighing process. The system requires manual assistance to operate, the degree of automation is not high, and the weighing accuracy is not too high. In addition, the system is only aimed at ordinary bulk materials, without a certain analysis of powdery dangerous goods, and without taking some necessary safety protection measures, it cannot be used in the weighing e...

Problems solved by technology

The system requires manual assistance to operate, the degree of automation is not high, and the weighing accuracy is not too high

In addition, the system is only aimed at ordinary bulk materials, without a certain analysis of powdery dangerous goods, and without taking some necessary safety protection measures, it cannot be used in the weighing environment of powdery dangerous goods

[0003] At present, the automatic weighing device for ordinary powdery materials has become mature, but in the domestic chemical industry, the weighing and unloading of powdery pyrotechnic products are still mostly stand-alone, and there has not been a special device for powdery pyrotechnic products. Automatic weighing and packing device for products

Most of the previous devices required manual assistance, resulting in low production efficiency and a low degree of automation

The quantitative weighing and transportation of products are all done manually, the work intensity is high, the environment is poor, and the dust will directly endanger the health of workers

Moreover, powdered pyrotechnics itself is a source of explosion and is extremely dangerous

In addition, when the dust reaches a certain concentration, when it encounters a heat source, a dust explosion will also occur, which has extremely strong destructive power.

At the same time, the weighing error is also arbitrary, which will directly affect the quality of the product
