Embodiment
According to Fig. 2～Fig. 5, a better embodiment of the present utility model is described below.
As shown in Figure 2, this closed powder injecting equipment 21 is installed on the top of the multiple groove 22 of band ladle.This closed powder injecting equipment 21 comprises a charging powder hopper 211, is positioned at charging powder hopper 211 belows and becomes to be communicated with the sealing powder injecting hopper 218 that connects, infrared electro receptor 213 and infrared electro projector 219 with two lateral opposite positions of the upper end that is separately positioned on this sealing powder injecting hopper 218, with in a side of this sealing powder injecting hopper 218, switch 214 is adjusted in one of setting.In the present embodiment, also a vibrator 210 is installed at the outer side of charging powder hopper 211, with appropriate location within sealing powder injecting hopper 218 one loose powder impeller 215 is installed, and it is connected with a micro-speed motor 217 that is located at sealing powder injecting hopper 218 outsides through a transmission hinge 215.
In this device 21, also comprise one and install the pilot circuit 3 of 21 one-tenth machine-electrical connections with this, as shown in Figure 3, in this pilot circuit 3, infrared electro receptor 213 constitutes one for powder proofing unit 31 with infrared electro projector 219, this pilot circuit also comprises one the confession powdery condition alarm unit 32 of reporting to the police and interrogating Chinese percussion instrument 321 and telltale 322 formations, the detection signal that this alarm unit 32 receives for powder proofing unit 31, and have one to adjust the detection signal output that switch 214 is controlled this confession powder proofing unit 31.
Working condition of the present utility model is as follows:
(1), when filling powder 212 in the charging powder hopper 211, also be full of powder in its underpart sealing powder injecting hopper 218, also be full of powder 212 in the multiple groove 22 of band ladle, production work is normal, pilot circuit 3 is not worked.
(2), powder is piled up in charging powder hopper 211, powder does not fall again, powder begins to descend in the sealing powder injecting hopper 218 of bottom, when arriving to a certain degree, start working for powder proofing unit 31, the infrared beam that infrared electro projector 219 is sent is received by infrared electro receptor 213, and changes into electrical signal; In the pilot circuit 3, adjusting switch 214 generally is to be in closure state, makes when feed lacks in the sealing powder injecting hopper 218, and report to the police news Chinese percussion instrument 321 and telltale 322 news are rung and indication, send warning.
(3), at the outer side of charging powder hopper 211, a vibrator 210 also is set, vibrator 210 is by a vibrator control unit 33 controls, vibrator control loop pilot circuit schematic diagram is as shown in Figure 4; When starting working for powder proofing unit 31, the vibrator control loop is switched on, and vibrator 210 begins vibration, and the powder vibrations are fallen in the charging powder hopper 211, is full of powder in the sealing powder bucket 218, makes for the 31 no infrared electro signal outputs of powder proofing unit.This process does not influence the works better of annotating the powder unit.
As shown in Figure 3, in the vibrator control unit 33, comprise a transfer lever 331, this transfer lever 331 comprises two contacts 3331 and 3332, it can be interrupted 210 one-tenth circuit of delay controller 333 and vibrator with contactor 332 and by contact 3331 and be connected, and vibrator 210 is intermittently shaken; Also can be connected by the 210 one-tenth circuit in contact 3332 and contactor 334 and vibrator, vibrator 210 can shake continuously.
(4), when charging powder hopper 211 powders tend to be zero, sealing powder bucket 218 powders of bottom descend, as mentioned above, for 31 work of powder proofing unit, pilot circuit 3 starts, and sends warning, powders continue to descend in the sealing powder bucket 218, produce and are also carrying out; In pilot circuit, also comprise one and be interrupted delay controller 34, connect behind this interruptions delay controller 34 for powder proofing unit 31 also and alarm unit 32 be connected in parallel; This moment, as shown in Figure 5, the power control circuit of this delay controller 34 and unit constituted a loop by these delay controller 34 time-delays; after time-delay for some time; action disconnects the power control circuit of whole unit and wheat flour detacher, compressor emergency shutdown, thereby the quality of production of assurance cored-wire.
Also to point out: if the staff is after action news Chinese percussion instrument 321 gives the alarm, feel a riot of sound, can temporarily open and adjust switch 214, make adjustment switch 214 be in off-state, but after charging powder hopper 211 is filled it up with powder, still need connect and adjust switch 214, it can be worked in pilot circuit.
