It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Features of various aspects of embodiments of the invention will be described in detail below. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced without these specific details. The following description of the embodiments is merely intended to better understand the present invention by illustrating examples thereof. The present invention is not limited to any particular arrangement or method provided below, but rather covers all product structures, any modifications, alterations, etc. of the method covered without departing from the spirit of the invention.

Example 1: referring to fig. 1, a non-contact type initiating explosive metering device includes a blanking mechanism, a distributing mechanism, a receiving and conveying mechanism, a medicine box, and a weighing mechanism. The blanking mechanism is a foldable raw material packaging mechanism and is arranged above the material distribution mechanism, a sufficient distance is kept between the blanking mechanism and the material distribution mechanism, the distance is generally 5 mm-10 mm, and the distance in the embodiment is 6 mm. In addition, unloading mechanism is provided with tilting mechanism, encapsulates after positive direction is loaded, then opens after the upset, avoids the upset in-process to appear spilling the medicine problem.

Feed mechanism is funnel type mechanism, and its below export is located and connects material transport mechanism top, and keeps having the clearance between the two, 5mm ~ 10mm of interval between feed mechanism top and the unloading mechanism, the distance between feed mechanism below export and the material transport mechanism entry is 5mm ~ 8mm, and the aforesaid is through the control of interval, can effectively avoid, and the medicine phenomenon can appear floating or spilling greatly in the interval, and the interval has too short can appear contact friction, and the potential safety hazard is great.

In addition, the surface finish of the material distributing mechanism is not lower than 1.6 mu m, and the material distributing mechanism is made of stainless steel materials so as to keep enough hardness and avoid accidental explosion deformation, and is clamped and fixed by a fixing bracket.

The inclination angle of the material distribution mechanism is 10-15 degrees, in the embodiment, the inclination angle is 12 degrees, so that the flow velocity of the initiating explosive can be effectively controlled by combining the surface finish, and the situation that the initiating explosive is exploded or is accumulated too slowly due to friction and collision caused by over-high speed is avoided.

The material distributing mechanism is a parallel double-material mechanism, namely a double-funnel structure, and corresponds to the two material receiving conveying mechanisms below respectively so as to improve the material distributing efficiency.

The inlet of the material receiving and conveying mechanism is of an equal-diameter cylindrical structure, and the diameter of the material receiving and conveying mechanism is 3-5 times of the diameter of the outlet below the material distributing mechanism, so that enough space is provided for preventing the primary explosive from floating. In addition, the bottom of the material receiving and conveying mechanism is provided with an inclined downward conveying channel, the inclination angle is 5-10 degrees, in the embodiment, the inclination angle is 7 degrees so as to keep the stable conveying of the primary explosive, and the inaccurate metering or the potential safety hazard increase caused by over-high speed or over-low speed is avoided. The conveying channel is connected with the vibrating mechanism, and the outlet of the conveying channel is positioned above the medicine box and keeps a distance with the medicine box, generally not higher than 10mm, 8mm in the embodiment. The vibration mechanism below the conveying channel is a spring piece, and the vibration amplitude of the spring piece is 0.5 mm-1 mm. And has a plurality of contact points with the bottom of the transfer channel to provide sufficiently uniform vibration to enable orderly and safe transfer of the initiating explosive to the cartridge. The staged vibration frequencies of the two receiving conveying mechanisms are different, the vibration amplitude of the two receiving conveying mechanisms is 0.8-1 mm when the two receiving conveying mechanisms start to vibrate quickly, the vibration amplitude of the other receiving conveying mechanism is 0.5-0.7 mm when the other receiving conveying mechanism stops vibrating, the other receiving conveying mechanism vibrates slowly, the quick vibration has high conveying speed, the quality of the initiating explosive can be improved quickly, and the slow vibration conveying speed is low, so that the initiating explosive conveying quality can be controlled accurately, and the metering accuracy can be controlled.

In this embodiment, when the contactless initiating explosive metering device actually works, the specific process is as follows:

step one, manually feeding the material box to the device 1, closing the explosion door, automatically operating the equipment, clamping the material box and turning over (completed by a pneumatic system).

Secondly, the initiating explosive is poured into the device 2, the initiating explosive is divided into two parts in the device 2 on average,

and thirdly, the primary explosive slides into the device 3, the device 3 is a material channel, the vibration driver device 3 starts to vibrate, and meanwhile, the spring piece and the material channel start to vibrate (the driving power is pneumatic).

In a fourth step, the primary explosive flows through the device 3 towards the device 4 (the devices 3, 4 are in one piece and do not rub against each other during vibration).

Fifthly, the transfer medicine box of the production line of the metering device 6 is carried out through a device 5 (an explosion-proof electronic scale).

The design changes the original contact type initiating explosive metering device into a non-contact type initiating explosive metering device. The potential safety hazard is reduced, and the safety and the operability of the initiating explosive device medicament are improved.

Example 2, in this embodiment, the structure is similar to that of example 1, except that the material distribution mechanism is also of a double-funnel structure, and only the vibration frequencies of the two material receiving and conveying mechanisms are kept consistent, so as to improve the stability and consistency of the transfer of the initiating explosive.

Example 3, the structure of the present embodiment is similar to that of example 1, except that there are only one receiving and conveying mechanism instead of two, and therefore the structure is simple and the transfer of the initiating explosive is easy to control.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solutions of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive various equivalent modifications or substitutions within the technical scope of the present invention, and these modifications or substitutions should be covered within the scope of the present invention.
