Detailed Description

The technical scheme of the invention is further specifically described by the following embodiments and the accompanying drawings.

The utility model provides a carbide stick machine-shaping material feeding unit, is including the multiunit feeder hopper 1 that sets up side by side, wherein 1 bottom discharge gate department of feeder hopper is provided with material pipe 2, and is provided with the control valve on the material pipe 2:

still including installing rectangle surrounding edge 3 on former feed inlet department, wherein offer the intercommunicating pore 4 that is used for installing the discharge gate of material pipe 2 on 3 lateral walls of surrounding edge, and still be provided with the opening in the 3 openings of surrounding edge and set up at Contraband template 5 towards intercommunicating pore 4 direction, Contraband template 5 level is provided with the closing plate 6 that is located the intercommunicating pore 4 top in the opening, and wherein 6 bottoms of closing plate are provided with baffle 7, baffle 7 is located between two sets of adjacent intercommunicating pores 4, and wherein 7 lateral walls of baffle respectively with the closing plate 6 bottom face and Contraband template 5 inside wall fixed connection that correspond, and the 7 bottoms of baffle extend to 3 places below the surrounding edge.

When in use, materials are led in through the feed hopper 1 and flow into the surrounding edges 3 at two sides of the baffle 7 through the material pipe 2 and the communicating holes 4, so that the two powder materials are not mixed in the process of feeding simultaneously, and the feeding efficiency is improved. In one embodiment, the required performance of two ends of the hard alloy rod is different, and two kinds of powder respectively enter from different inner cavities of the feeding hopper 1, the material pipe 2 and the surrounding edge 3 on two sides of the baffle 7 and are accumulated at two ends of a die in a forming press at the same time, so that the powder is pressed into hard alloy rod blanks with two ends made of different materials. In the above process, the powder entering the surrounding edge 3 can be prevented from spreading to the outside production workshop by the sealing plate 6.

As shown in fig. 1, a vibration motor 8 is arranged at the top of the sealing plate 6, a sliding opening 9 corresponding to the side wall of the Contraband template 5 is vertically arranged on the side wall of the surrounding edge 3, wherein a mounting hole is formed in the bottom wall of the sliding opening 9, a spring 10 extending into the sliding opening 9 is arranged in the mounting hole, a magnetic connecting block 11 is arranged at the top end of the spring 10, and a bolt 13 with the tail end corresponding to the outer side wall of the Contraband template 5 in threaded connection is arranged at the top end of the magnetic connecting block 11.

In this embodiment, the magnetic connecting block 11 is adapted to the width of the sliding opening 9, wherein an arc notch 12 for accommodating the shaft of the bolt 13 is formed in the top end surface of the magnetic connecting block 11, the bottom end of the sliding opening 9 has a height of Contraband, and the bottom end of the template 5 is lower than the bottom end of the communicating hole 4, wherein the bottom end of the Contraband template 5 is lower than the bottom end of the communicating hole 4.

When feeding, the Contraband template 5, the closing plate 6 and the baffle 7 are driven to shake through the work of the vibrating motor 8, and then the powder on the Contraband template 5 inside wall and the baffle 7 side wall is shaken off, so that the powder quickly drops into the molding equipment, and the powder cannot be deposited on Contraband template 5 inside wall or baffle 7 side wall for a long time and the subsequent feeding work is influenced.

As shown in fig. 1, when the vibration motor 8 drives the sealing plate 6 and the Contraband type plate 5 to shake in the surrounding edge 3, the bolt 13 is driven to move downwards in the sliding opening 9, at this time, the bolt 13 extrudes the spring 10 through the magnetic connecting block 11 to shrink the spring, so that the shrunk spring 10 is stretched, and the Contraband type plate 5, the sealing plate 6 and the baffle 7 are pushed to recover to the original position, thereby realizing the purpose of shaking the above assembly, and finally realizing the purpose of shaking off the powder adhered to the side wall of the above assembly.

And Contraband template 5 is in the in-process of up-and-down motion, because Contraband template 5 inside wall bottom edges and corners slope is provided with inclined plane 14 for it is when the lapse, Contraband template 5 bottom can scrape the powder that probably adheres on the surrounding edge 3 inside wall through inclined plane 14, and then makes and scrapes the powder and flow into the processing in the former, prevents that the powder adhesion from influencing the problem of follow-up feeding efficiency and effect on the surrounding edge 3 inside wall.

In the process, the top end of the sliding opening 9 supports against the rod body of the bolt 13 to prevent the bolt 13 from continuously sliding upwards, the contracted spring 10 and the magnetic connecting block 11 support against the rod body of the bolt 13 which moves downwards by a certain range, so that the limitation of the upper and lower ranges of the Contraband template 5 in the surrounding edge 3 is indirectly realized, the problem that the sealing plate 6 is driven to move to the position below the communicating hole 4 and the feeding work of the sealing plate is influenced due to the overlarge upper and lower displacement range of the sealing plate is solved, or the problem that the lower half part of the sliding opening 9 is opened due to the overlarge upward movement range of the Contraband template 5 and powder in the surrounding edge 3 flows out through the sliding opening 9 is solved.

When the combined type plate is used specifically, Contraband type plates 5, the sealing plate 6 and the baffle plate 7 can be detached from the surrounding edge 3 by detaching the bolts 13, so that the combined type plate can be replaced or cleaned, wherein the connecting stability between the bodies of the bolts 13 and the side walls of the arc-shaped notches 12 is improved by magnetic connection between the bodies of the bolts 13 and the side walls.

The outside of the surrounding edge 3 is provided with a blocking piece 15 corresponding to the sliding opening 9, wherein a screw hole in threaded connection with the rod body of the bolt 13 is formed in the blocking piece 15, the width of the blocking piece 15 is larger than that of the sliding opening 9, and arc-shaped parts are arranged at the upper end and the lower end of the blocking piece 15 in an outward turning mode.

When Contraband template 5 receives external force to influence and reciprocates in surrounding edge 3, it can drive bolt 13 and slide in sliding opening 9, and bolt 13 then can drive separation blade 15 and reciprocate in the surrounding edge 3 outside, seal the opening in the sliding opening 9 outside through separation blade 15 this moment, and then to the spring 10 after the extrusion shrink in the sliding opening 9 play fixed seal effect, prevent that the spring 10 deformation position after the shrink from protruding in sliding opening 9, and then promote spring 10's security.

The present invention has been described in detail, but the above description is only a preferred embodiment of the present invention, and is not to be construed as limiting the scope of the present invention. All equivalent changes and modifications made within the scope of the present invention shall fall within the scope of the present invention.
