At present, the current situation of the production line of the initiating explosive devices in China is not optimistic, the phenomena of equipment aging, low automation degree, man-mountain tactics and the like generally exist, particularly the process of separating the upper cover of the mold is adopted, and a plurality of manufacturers still continue to operate by hands or upgrade the production line into the operation by mechanical hands. The manual operation has extremely low production efficiency, and needs a large amount of workers to participate, so that the production cost is increased, and the workers need to bear great labor intensity due to endless repeated single labor; the manipulator is used for grabbing the upper cover of the mould, a mould positioning mechanism needs to be additionally arranged, and the pneumatic driving type manipulator is inaccurate in control and difficult in speed adjustment; the servo motor driven type manipulator is flexible and reliable in action and accurate in positioning, but the manufacturing cost and the maintenance cost of the explosion-proof type servo manipulator are high, the requirement on the technical level of operators is high, and therefore part of enterprises are difficult to bear.

Disclosure of Invention

The invention aims to: the problem of in the automatic assembly production process of initiating explosive devices such as ignition device, throwing pipe, electric explosion pipe, do not influence the transmission speed of initiating explosive device between each station, through mechanical structure's ingenious setting, drive three group's belt pulleys and a set of gear simultaneously by a driving source, make two sets of belt pulleys that contact with the mould upper cover rotate the opposite direction, drive the mould upper cover and do the continuous conveying on the guide rail that inclines 10 and return the transfer chain, all the other moulds then continue to advance along horizontal transport platform, accomplish mould and mould upper cover autosegregation is solved.

The technical scheme for realizing the purpose is as follows:

the mold cover separating device is composed of a guide rail device, a front conveying device, a belt adjusting device and a rear conveying device. The guide rail device is used for separating and transferring the upper cover of the mould; the front conveying device is used for driving the upper cover of the mold to smoothly enter the guide rail device; the belt adjusting device is used for adjusting the tension force of the belt, and the ten bearings are adjusted by the springs to be kept in close contact with the belt at all times, so that the upper cover of the mold is ensured to be obliquely and continuously conveyed along the guide rail device; the rear conveying device is used for driving the upper mold cover to advance on the guide rail and conveying the separated upper mold cover to the return conveying line. The mold to be separated from the upper mold cover moves on the conveying belt at a speed of 20 m/min, a rectangular groove is formed in the outer diameter of the upper mold cover, a shifting fork in the inclined guide rail device enters the rectangular groove, the mold is conveyed on the conveying belt at the original speed, the upper mold cover moves upwards along the inclined guide rail under the driving of the shifting fork, the upper mold cover is separated from the middle mold of the mold, the requirement for automatically separating the upper mold cover is met, the separated upper mold cover is transmitted back to the original station through the conveying belt, and other molds are continuously transmitted to the subsequent station for assembly.

The method is characterized in that: simple structure, full automation, it is efficient.
