Description

Technical Field

[0001] This invention relates to the field of vibrating feeder control, and more particularly to an electrical modification circuit for a vibrating feeder. Background Technology

[0002] Vibrating feeders are widely used in various industries such as mining, metallurgy, coal, building materials, light industry, chemical industry, power, machinery, and grain processing. They are used to uniformly, continuously, or quantitatively feed lumpy, granular, and powdery materials from storage bins to receiving devices. During operation, the amplitude, current of the vibrating motor, and surface temperature of the motor should be checked frequently. The feeder should have uniform front-to-back amplitude, without lateral swaying, and the motor current should be stable. If any abnormality is found, the machine should be stopped immediately. However, in existing technology, the electrical control circuit of the feeding device, after prolonged vibration, can cause excessive load on the crusher. The circuit lacks overcurrent protection, leading to circuit breaks and motor burnout. Summary of the Invention

[0003] In view of the problems existing in the prior art, the present invention discloses an electrical modification circuit for a vibrating feeder, comprising: an AC contactor KM, a first time relay KT1, an intermediate relay KA, and a second time relay KT2 connected in parallel;

[0004] One end of the AC contactor KM is connected to the normally closed contact of the intermediate relay KA, and the normally closed contact of the intermediate relay KA is connected to the manual switch SA.

[0005] The delayed closing contact of the first time relay KT1 is connected to the delayed opening contact of the second time relay KT2, and the delayed closing contact of the first time relay KT1 is connected to the normally closed contact of the intermediate relay KA.

[0006] The coil of the intermediate relay KA is connected to the delayed disconnect contact of the second time relay KT2, and the delayed disconnect contact of the second time relay KT2 is connected to the delayed closing contact of the first time relay KT1.

[0007] The coil of the second time relay KT2 is connected to the normally open auxiliary contact of the intermediate relay KA, and the delayed closing contact of the first time relay KT1 is connected in parallel with the normally open auxiliary contact of the intermediate relay KA.

[0008] The output terminal of the manual switch SA, the delayed closing contact of the first time relay KT1, and the normally open auxiliary contact of the intermediate relay KA connected in parallel is connected to the normally open auxiliary contact of the main contactor KM1 of the crusher. The normally open auxiliary contact of the main contactor KM1 is connected to the normally closed auxiliary contact of the motor protector QF1. When the crusher is not started, the vibrating feeder does not work.

[0009] The first time relay KT1 and the second time relay KT2 are JS14P relays.

[0010] The model of the AC contactor KM is CJ20_100.

[0011] The intermediate relay KA is model CDZ9L-S4P.

[0012] The manual switch SA is model LA38_11.

[0013] By adopting the above technical solution, the present invention provides an electrical modification circuit for a vibrating feeder. This circuit structure effectively solves the problem of excessive feeding by the feeder. It can control the feeder to automatically feed, reducing operator workload and achieving the goal of reducing manpower and increasing efficiency. This circuit structure can be interlocked with the crusher; when the crusher is not working, the circuit structure does not operate. Furthermore, the addition of a motor protector ensures the motor operates safely, preventing burnout due to overload and significantly saving production costs. This circuit structure can also be applied to other feeding systems, and its practical application has shown excellent results. Attached Figure Description

[0015] Figure 1 This is a schematic diagram of the electrical modification circuit for the small crushing vibrating feeder of the present invention. Detailed Implementation

[0016] To make the technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention:

[0017] like Figure 1The electrical modification circuit of a vibrating feeder shown includes an AC contactor KM, a first time relay KT1, an intermediate relay KA, and a second time relay KT2 connected in parallel. One end of the AC contactor KM is connected to the normally closed contact of the intermediate relay KA, and the normally closed contact of the intermediate relay KA is connected to a manual switch SA. The delayed closing contact of the first time relay KT1 is connected to the delayed opening contact of the second time relay KT2, and the delayed closing contact of the first time relay KT1 is connected to the normally closed contact of the intermediate relay KA. The coil of the intermediate relay KA is connected to the delayed opening contact of the second time relay KT2. The delayed disconnect contact of the second time relay KT2 is connected to the delayed closing contact of the first time relay KT1; the coil of the second time relay KT2 is connected to the normally open auxiliary contact of the intermediate relay KA; the delayed closing contact of the first time relay KT1 and the normally open auxiliary contact of the intermediate relay KA are connected in parallel; the output terminal of the manual switch SA, the delayed closing contact of the first time relay KT1, and the normally open auxiliary contact of the intermediate relay KA are connected to the normally open auxiliary contact of the main contactor KM1 of the crusher; the normally open auxiliary contact of the main contactor KM1 is connected to the normally closed auxiliary contact of the motor protector QF1; when the crusher is not started, the vibrating feeder is not working.

[0018] Furthermore, the first time relay KT1 and the second time relay KT2 are JS14P relays with a coil voltage of AC220V and a delay time of 99S.

[0019] Furthermore, KM1 is an AC contactor with model number CJ20_160 and coil voltage of AC220V.

[0020] Furthermore, the model of the AC contactor KM is CJ20_100, and the coil voltage is AC220V.

[0021] Furthermore, the intermediate relay KA has the model number CDZ9L-S4P and a coil voltage of AC220V.

[0022] Furthermore, the manual switch SA model is LA38_11.

[0023] In operation: When the manual switch SA is closed, the AC contactor KM and the first time relay KT1 are energized and engaged. The main contacts of the AC contactor KM close, and the motor M starts running. After a period of operation (determined by the first time relay KT1), the delayed-closing contact of the first time relay KT1 closes, connecting the intermediate relay KA and the second time relay KT2. The normally closed contact of the intermediate relay KA opens, de-energizing the AC contactor KM and stopping the motor M. After another period of time (determined by the second time relay KT2), ​​the delayed-opening contact of the second time relay KT2 opens, de-energizing and releasing the intermediate relay KA. The normally closed contact of the intermediate relay KA closes, re-energizing the AC contactor KM coil, and the motor restarts.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
