Detailed Description
The technical solutions of the embodiments of the present invention will be described in further detail with reference to the accompanying drawings, and these embodiments are only used for illustrating the present invention, but not for limiting the present invention.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the term "connected" is to be interpreted broadly, for example, as a fixed connection, a detachable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.
In the description of the present invention, it should be noted that "a plurality" means two or more.
As shown in fig. 1, an embodiment of the present invention provides an automatic power-off device for belt flash, which includes a spring 1, a lever 2, a proximity switch 3 and a collection frame 4, wherein the spring 1 is located at a fulcrum position of the lever 2 and between the lever 2 and the collection frame 4, two ends of the spring 1 are vertically abutted against the lever 2 and the collection frame 4, and the side of the collection frame 4 not contacted with the spring 1 is provided with the proximity switch 3; one end of the lever 2 close to the proximity switch 3 and one side opposite to the proximity switch 3 comprise a metal sheet, and the proximity switch 3 sends an electric signal to a control system of the belt system according to whether the metal sheet is positioned in the detection distance of the proximity switch 3, so that the running state of the belt system is controlled.
Further, the metal sheet includes an iron sheet, a copper sheet, an aluminum sheet, or the like, and in this embodiment, the metal sheet may be an iron sheet. The proximity switch 3 includes a cylinder type, a square type, a trench type, a punch type, and a separation type, and in this embodiment, the proximity switch 3 is a cylinder type, and the proximity switch 3 is an inductive type proximity switch. When the metal sheet at one end of the lever 2 approaches the direction of the proximity switch 3 and is positioned within the detection distance of the proximity switch 3, the magnetic field inside the proximity switch 3 changes, and then is processed by an internal amplifying circuit and converted into an electric signal, and the signal is transmitted to a control system of the belt system, so that the belt system is controlled to be in a non-operation state.
Further, an upright post is arranged between the lever 2 and the collecting frame 4, two ends of the upright post are vertically fixed on the lever 2 and the collecting frame 4 respectively, and the spring 1 is sleeved on the upright post. The side lower part of the belt system blanking hopper is provided with a material overflow port, the device is positioned below the material overflow port of the belt system blanking hopper, and one end of the lever 2 close to the proximity switch 3 is positioned below the material overflow port. When materials overflow from the overflow port, the materials fall to one end of the lever 2 close to the proximity switch 3, the weight of one end of the lever 2 close to the proximity switch 3 is increased, and the lever starts to move towards the proximity switch 3 and presses the spring 1 close to one side of the proximity switch 3.
Further, the position of the column at the lever 2 is determined according to the principle of lever balance, in the present embodiment, the columnIn the central position of the lever 2, according to the lever balancing principle: power x power arm-resistance x resistance arm, i.e. F1×L1＝F2×L2In which F is1And F2The weights, L, of the end of the lever 2 close to the proximity switch 3 and the end far from the proximity switch 3, respectively1And L2The distances between the upright post and one end of the lever 2 close to the proximity switch 3 and one end far away from the proximity switch 3 are respectively. By the lever balance principle, when the material does not fall on one end of the lever 2 close to the proximity switch 3, the lever 2 is in a balance state; when the material falls on one end of the lever 2 close to the proximity switch 3, at the moment, the weight of one end of the lever 2 close to the proximity switch 3 is increased, one end of the lever 2 close to the proximity switch 3 starts to move towards the proximity switch 3 and presses the spring 1 close to one side of the proximity switch 3, the proximity switch 3 detects a displacement signal of the lever 2 according to a metal sheet on the lever 2, and when the displacement signal of the lever 2 is within the detection distance range of the proximity switch 3, the proximity switch 3 sends an electric signal to a control system of a belt system, so that the belt system is controlled to be in a non-running state; when the displacement signal of the lever 2 is not within the detection distance range of the proximity switch 3, the proximity switch 3 sends an electric signal to a control system of the belt system, so that the belt system is controlled to be in a running state.
Further, the proximity switch 3 is used to connect to a relay in a control cabinet of the belt system, which is connected to a PLC control system of the belt system. When the displacement signal of the lever 2 is within the detection distance range of the proximity switch 3, the proximity switch 3 outputs an electric signal, the relay transmits the electric signal of the proximity switch 3 to the PLC control system, so that the belt system is controlled to be in a non-running state, and the picture of the PLC control system can display emergency stop alarm information to remind a worker to clean materials.
The working process and the working principle of the embodiment are as follows:
during the feeding process of the belt system, materials overflow from the overflow port of the blanking hopper and fall onto the lever 2, and fall onto one end of the lever 2 close to the proximity switch 3. At this moment, the weight of one end of the lever 2 close to the proximity switch 3 is increased, one end of the lever 2 close to the proximity switch 3 starts to move towards the direction of the proximity switch 3, when the proximity switch 3 detects that the lever 2 is within the detection distance range of the proximity switch 3, the proximity switch 3 outputs an electric signal, the relay transmits the electric signal of the proximity switch 3 to the PLC control system, the system picture displays alarm information, and meanwhile, the belt system stops running immediately. At the moment, a worker cleans the blanking hopper and the materials on the lever 2 on site, after the materials are cleaned, the displacement signal of the lever 2 is not within the detection distance range of the proximity switch 3, the picture alarm state of the PLC control system is released, and the belt system recovers normal operation.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and replacements can be made without departing from the technical principle of the present invention, and these modifications and replacements should also be regarded as the protection scope of the present invention.
