Specific embodiment

Below with reference to examples and drawings, the utility model is described in further detail, but the reality of the utility model It is without being limited thereto to apply mode.

Embodiment 1:

As shown in Figure 1 and Figure 2, in the present embodiment, a kind of powder charge plate pressing device, including auxiliary mounting deck 1, main lifter plate 8, it is used to control secondary lifter plate 9 relative to main lifting on main lifter plate 8 positioned at the secondary lifter plate 9 of main 8 lower section of lifter plate, setting Plate 8 exists on auxiliary mounting deck 1 for controlling main lifter plate 8 in the mobile secondary lifter plate driving structure 22 of vertical direction, setting The mobile main lifter plate driving structure of vertical direction, be arranged on secondary lifter plate 9 and the pressure head 18 with powder charge through-hole and with master Lifter plate 8 is sequentially connected and is capable of the red needle 17 of sliding opposite with the powder charge through-hole on pressure head 18, sets below the pressure head 18 It is equipped with the powder charge plate 10 with powder charge through-hole alignment, the powder charge through-hole is communicated with drug feeding pipeline, the axis of powder charge through-hole and master The moving direction of lifter plate 8 is parallel.

Powder charge through-hole in pressure head 18 is communicated with drug feeding pipeline connecting hole 20, and drug feeding pipeline and drug feeding pipeline connecting hole 20 connect It is logical.When needing to carry out the work of powder charge, pressing, explosive is supplemented into powder charge through-hole by using drug feeding pipeline, main lifter plate drives Dynamic structure drives main lifter plate 8 and secondary lifter plate 9 synchronous mobile to powder charge plate 10, until pressure head 18 is contacted with powder charge plate 10, The station for needing to be packed into explosive on powder charge through-hole and powder charge plate 10 at this time is aligned.Secondary lifter plate driving structure 22 is in the shape unclamped State, secondary lifter plate driving structure 22 would not limit main lifter plate 8 and continue to move down, and main lifter plate 8 drives red needle 17 to carry out It moves down, red needle 17 squeezes out downwards the explosive in powder charge through-hole, and the explosive in powder charge through-hole, which enters on powder charge plate 10, to be needed It is packed into the station of explosive.As needed, red needle can continue to move down and compress explosive.

This programme is easy to implement periodic cycle operation, is conducive to the precision and efficiency that improve dosing, and output Uniform in quality.Main lifter plate driving structure can remotely be controlled using controller, improve the automatic of powder charge process Change degree, and staff is avoided directly to contact with explosive, improve the safety of powder charge process.

As needed, the powder charge through-hole can be designed as grade, can be by the precision controlling of powder charge in milli with this Meter level, to meet the micro powder charge demand of millimeter class precision.And due to the design of drug feeding pipeline connection powder charge through-hole, being convenient for will Explosive is uniform, it is quantitative be transported in powder charge through-hole, the opening down direction powder charge plate 10 of powder charge through-hole, in the effect of red needle 17 Under, it is difficult to generate residual in powder charge through-hole, so that actual dosage is identical as the design dosage that drug feeding pipeline is conveyed, make The precision for obtaining dosing is high.

Risk is ignited in order to avoid explosive remains or exists, red needle 17 is slidingly sealed with powder charge via design, works as punching Needle 17 is opposite with powder charge through-hole when sliding, and can be avoided explosive and remains in the gap between red needle 17 and powder charge through-hole, or keeps away Exempt to cause the explosive inflammation in gap to explode because of red needle 17 and the frictional heat generation of powder charge through-hole, makes red needle 17 and powder charge through-hole Air can also be reduced by, which being slidingly sealed, enters in powder charge through-hole, so that explosive be avoided to contact with oxygen.

Embodiment 2:

As shown in Figure 3, Figure 4, on the basis of the above embodiments, in the present embodiment, the pressure head 18 is close to main lifting One end of plate 8 offers the stroke hole that and diameter coaxial with powder charge through-hole is greater than powder charge through-hole, slides peace in the stroke hole Equipped with the top stem casing 15 for having stepped hole, the aperture of stepped hole is directed toward powder charge through-hole, and one end of the red needle 17 passes through mandril It covers the stepped hole in 15 and is coupled with powder charge through-hole, the other end of red needle 17 is located in the macropore of stepped hole, the rank Sliding is provided with the red needle mandril 14 connecting with main lifter plate 8 in the macropore in terraced hole.

One end of red needle 17 is limited in stepped hole using the cooperation of top stem casing 15 and red needle mandril 14, red needle 17 it is another One end is coupled with powder charge through-hole, the both ends of red needle 17 can be made to be supported with this, so as to improve red needle 17 Stability and rigidity are beneficial to prevent 17 bending deformation of red needle or fracture.One end of red needle 17 is set to be arranged in powder charge through-hole Enough make red needle 17 and powder charge through-hole remain matched state, additionally it is possible to save make red needle 17 and powder charge through-hole alignment when Between, working efficiency can be improved with this.

Top stem casing 15 passes through with red needle mandril 14 to be coupled and can satisfy the use demand, without using other connections Structure is attached, and avoids complex structural designs, and top stem casing 15 and red needle mandril 14 can be made to realize quick assembling or fast The function of quick-detach can be realized the various sizes of red needle 17 of quick-replaceable to adapt to the pressure head with different size powder charge through-holes 18.In the present embodiment, other contents not described are same as the previously described embodiments, therefore do not repeat.

Embodiment 3:

As shown in figure 4, on the basis of above-described embodiment 3, in the present embodiment, the aperture of the red needle 17 and stepped hole Between be provided with T-type red needle set 19.Red needle set 19 is coupled with stepped hole, and red needle set 19, which is designed as T-type, can prevent from rushing Needle guard 19 falls off from the aperture of stepped hole.The aperture clearance fit of red needle set 19 and stepped hole, by that can make to rush there are gap There is needle 17 space centainly finely tuned to avoid red needle 17 by the shadow of mismachining tolerance to adapt to mismachining tolerance bring assembling deviation It rings and bending deformation, movement are interfered or fractureed, 19 sets of outsides in red needle 17 is covered by using red needle, can be avoided red needle 17 directly absorb impact and there are bending deformation or the risks to fracture.It can between the red needle set 19 and the aperture of stepped hole Setting elastic cushion can reduce the generation of noise and play the work of buffering in the case where 17 fine adjustment function of red needle is unaffected With mitigating the stress during 17 automatic adjusument of red needle more, avoid 17 bending deformation of red needle.It is other in the present embodiment The content not described is same as the previously described embodiments, therefore does not repeat.
