The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Refer to Fig. 1 to Fig. 3, a kind of hopper 100 providing for embodiment of the present invention, for being installed on injection machine, so that for example plastic raw materials of material to be provided to injection machine.Hopper 100 comprises feed bin 11, doffer 12 and switching device shifter 13.
Upper material blanking tube 120 is connected in the second port one 104, and in the present embodiment, upper material blanking tube 120 can be one-body molded with feed bin 11.Dropping material pipe 122 is connected in described injection moulding machine.Dropping material pipe 122 is provided with fixed head 1221 away from one end of upper material blanking tube 120, and the length of fixed head 1221 and width are greater than respectively the diameter of dropping material pipe 122.Fixed head 1221 is for being installed on described injection moulding machine by hopper 100.
Described switching device shifter 13 comprises the handoff block 131 of lengthwise shape.Handoff block 131 comprises upper surface 1310 and lower surface 1311.Spacing between described upper and lower surperficial 1310,1311 equals the height of connection chamber 1214.In handoff block 131, be formed with the material dropping channel 132He Qingliao road 133 that connects upper and lower surperficial 1310,1311.Wherein, material dropping channel 132 is vertical connects described upper and lower surperficial 1310,1311.And described Qing Liao road 133 tilts to connect described upper and lower surperficial 1310,1311.Described material dropping channel 132 and described Qing Liao road 133 interval between described upper surface 1310 is greater than the diameter of material blanking tube 120.Upper surface 1310 two ends are raised with the first barrier rib 1312 and the second barrier rib 1313.On upper surface 1310, be also formed with the first positioning convex 1314, the second positioning convex 1315 and the 3rd positioning convex 1316 of each interval.The first positioning convex 1314, the second positioning convex 1315 and the 3rd positioning convex 1316 have certain elasticity.Wherein, the first positioning convex 1314 equals locating slot 1217 to the spacing of upper material blanking tube 120 to the spacing of material dropping channel 132.The spacing in the 3rd positioning convex 1316 Dao Qingliao roads 133 equals locating slot 1217 to the spacing of upper material blanking tube 120.The spacing of the first positioning convex 1314 to second positioning convex 1315 equals locating slot 1217 to the spacing of bit-avoiding slot 1218.The second positioning convex 1315 equals locating slot 1217 to the spacing of bit-avoiding slot 1218 to the spacing of the 3rd positioning convex 1316.
Described switching device shifter 13 also comprises a clear material pipe 134.Described clear material pipe 134 is communicated with described Qing Liao road 133 on lower surface 1311.In the present embodiment, clear material pipe 134 be positioned on lower surface 1311 away from one end of material dropping channel 132 and and handoff block 131 one-body molded.
When starting to install, the sidewall 1212 of described doffer 12 is not connected with upper wall 1210, lower wall 1211, thereby for being installed, the position of sidewall 1212 forms breach between upper and lower wall 1210,1211, handoff block 131 is slided and is arranged in connection chamber 1214 from this breach, then, sidewall 1212 is connected on upper wall 1210, lower wall 1211 to complete installation.Because the height of handoff block 131 and connection chamber 1214 is equal, the upper surface 1310 of handoff block 131 is resisted against the upper wall 1210 of connector 121, and the lower surface 1311 of handoff block 131 is resisted against the lower wall 1211 of connector 121.The first barrier rib 1312 of handoff block 131, the second barrier rib 1313 exceed upper wall 1210 and when sliding, skid off connection chamber 1214 to prevent handoff block 131.
Refer to Fig. 3, when producing, handoff block 131 is in primary importance in connection chamber 1214, and the first positioning convex 1314 is arranged in locating slot 1217, the second positioning convex 1315 is arranged in bit-avoiding slot 1218, and material dropping channel 132 is communicated with upper material blanking tube 120 and dropping material pipe 122.Material in feed bin 11 successively through material blanking tube 120, material dropping channel 132 and dropping material pipe 122 enter injection moulding machine and produce.
Refer to Fig. 4, when suspending production, promote handoff block 131 and slide into the second place in connection chamber 1214, the second positioning convex 1315 is snapped in locating slot 1217, the 3rd positioning convex 1316 snaps in bit-avoiding slot 1218.Now the upper material dropping channel 132 of upper surface 1310 sealing of handoff block 131, is maintained in feed bin 11 material.
Refer to Fig. 5, when clear material, promote handoff block 131 and in connection chamber 1214, slide into the 3rd position, the 3rd positioning convex 1316 is snapped in locating slot 1217.Now Qing Liao road 133 is communicated with upper material blanking tube 120 and clear material pipe 134, and material flows out through upper material blanking tube 120, Qing Liao road 133 and clear material pipe 134 successively, to empty the material in feed bin 11.
Be understandable that, for the person of ordinary skill of the art, can make other various corresponding changes and distortion by technical conceive according to the present invention, and all these change and distortion all should belong to the protection domain of the claims in the present invention.
