Problems solved by technology

Due to the limitation of the charging principle, the charge is less than 20 volumes at a time, and the mechanical device is complicated and huge. There is heat generated by high-speed friction between the screw shaft and the powder, and between the powder and the steel pipe, which cannot reach intrinsic safety. ;Because the outer wall of the paper tube is impregnated with a wax film, it is impossible to print the production date on the outer surface of the drug roll at the same time as it is produced, which meets the requirements of the "General Rules for Warning Marks and Registration Marks of Civil Explosives" that will be implemented on May 1, 2011 It will be very difficult to implement "the content of the registration mark includes the name of the production unit or place of production, and the date of production"
[0003] The patent CN101592462A "Industrial Powder Explosive Cartridge Charging and Packaging Technology and Vibration Charging Machine" published on December 1, 2009, the cartridges must be "cartridge sorted and fixed" together to form a relatively fixed cartridge Because it is impossible to "fix" a large number of cartridges together, it affects the improvement of production efficiency; its vibrating charge relies on the motor reducer to drive the cam, which causes the vibration of related parts, and its vibration noise is large, optional Weaknesses such as small excitation force, poor feasibility of industrial production, and direct selection of vibration motor to achieve high efficiency, practice has proved that, when the powder is fixed, the diameter of the drug roll is fixed, and the vibration parameters are consistent, the charging effect is proportional to the size of the charging excitation force. Proportional; because the charge machine uses a solid structure, the powder rolls become a fixed whole during the vibration charge process, which increases its own rigidity and weakens the vibration from the cam, which affects the charge effect and cannot achieve the desired effect. The charge density of the drug can only be achieved by compacting the drug powder in the drug roll through the "compacting mechanism", and multiple pressing rods (consistent with the number of drug rolls) are required, which is also one of the reasons that affect the actual promotion. one

Embodiment Construction

[0076] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0077] The invention provides an industrial powdery explosive charging process, which is realized through the following steps:

[0078] Step 1: Put the empty plastic tubes into the turnover mold in sequence;

[0079] Step 2: Pull and transport the turnover mold to the charging process, and carry out the positioning charging of the turnover mold. The charging process adopts vibration filling to complete the charging of all empty plastic tubes in the turnover mold; cleaning process;

[0080] Step 3: The plastic tube in the turnover mold is pulled and transported to the sealing process, and the plastic tube is sealed and cut;

[0081] Step 4: After the turnover mold is turned 90 degrees, it is transported to the mold unloading and tube ...

Abstract

The invention discloses an industrial powder explosive loading process and an explosive loading machine set thereof, wherein the process comprises five basic steps such as loading powder explosive in a pipe, loading the powder explosive in a locating manner, sealing, cutting-off, unloading the pipe, transporting and discharging. The explosive loading machine set comprises a circulating traction transporting device, a turnover mold, a vibrating explosive loading device, a sealing device, a sealing membrane rolling / unrolling device, an overturning device and a mould pipe unloading and loading device; the plastic pipe is arranged on the turnover mold; the vibration explosive loading, the sealing and the pipe unloading and loading are sequentially finished on the plastic pipe through the circulating traction device. The adopted plastic pipe is manufactured by carrying out blow molding on polyethylene, which is convenient for carrying out the sealing working procedure and simultaneously can prevent the powder explosive from dampening and meet warning signs specified by the nation, such as the production unit, the production data and the like printed on the external surface of the plastic pipe. The process has the advantages of simple structure, convenience for operation, little occupied area, more than 320 volumes of loaded explosive at a time; and each set of explosive loading machine set charges more than 3.8 tons of powder explosive per hour.

Description

technical field [0001] The invention relates to the technical field of explosives, in particular to an industrial powdery explosive charging process and a charging unit thereof. Background technique [0002] The principle of the conventional powder explosive charging machine is to push the powder into a single paper tube by the rotating screw shaft, and then seal a section of the paper tube. In order to prevent moisture, the outer wall of the paper tube is impregnated with wax film. Due to the limitation of the charging principle, the charge is less than 20 volumes at a time, and the mechanical device is complicated and huge. There is heat generated by high-speed friction between the screw shaft and the powder, and between the powder and the steel pipe, which cannot reach intrinsic safety. ;Because the outer wall of the paper tube is impregnated with a wax film, it is impossible to print the production date on the outer surface of the drug roll at the same time as it is prod...
