Detailed Description

The invention will be further described with reference to the accompanying drawings, which are provided for illustration of specific embodiments of the invention and are not to be construed as in any way limiting the invention, as follows:

as shown in fig. 1-3 and referring to fig. 4, a filter cloth deviation rectifying switch comprises a fixed frame 1, a swing rod 2 and a supporting leg 3. The legs 3 have vertically oriented fixing slots 4. The fixing clip 6 is a U-shaped bolt. The fixing frame 1 includes a housing 101 having a box structure with a cavity therein and a fixing rod 102 fixed to an outer side surface of the housing 101. The fixing frame 1 is fixed on the supporting leg 3 through a fixing clip 6 and can be adjusted up and down by depending on the fixing groove hole 4. Meanwhile, the fixing rod 102 has a length such that the fixing frame 1 can be horizontally adjusted in the axial direction of the fixing rod 102. The swing rod 2 is rotationally fixed in the cavity of the fixed mount 1. The inductor 5 is fixed on the side wall of the box body structure of the fixed frame 1 and extends into the box body structure of the fixed frame 1. The inductor 5 is located on the rotating path of the swing rod 2, so that after the swing rod 2 rotates to a certain angle, the inductor 5 can be shielded, and a corresponding signal is triggered. The sensor 5 is electrically connected with an external PLC and a power supply by adopting a proximity inductive switch. The sensor 5 may be any one of a capacitive proximity sensor switch, a photoelectric sensing proximity sensor switch, and a hall proximity sensor switch. Capacitive proximity inductive switch: the measurement of such a switch is usually one plate that constitutes a capacitor, while the other plate is the housing of the switch. This housing is typically grounded or connected to the housing of the device during measurement. When an object moves towards the proximity inductive switch, whether it is a conductor or not, the dielectric constant of the capacitor is always changed due to the proximity of the object, so that the capacitance is changed, the state of a circuit connected with the measuring head is changed, and the switch can be controlled to be switched on or switched off. The object to be detected by the proximity sensing switch is not limited to a conductor, and may be an insulating liquid, powder, or the like. Hall approaches inductive switch: the hall element is a magneto-sensitive element. A switch made using a hall element is called a hall switch. When the magnetic object moves close to the Hall switch, the Hall element on the switch detection surface changes the state of the internal circuit of the switch due to the Hall effect, thereby identifying the existence of the magnetic object nearby and further controlling the on or off of the switch. The detection object of such a proximity inductive switch must be a magnetic object. Photoelectric type proximity switch: a switch made by using the photoelectric effect is called a photoelectric switch. The light emitting device and the photoelectric device are arranged in the same detection head according to a certain direction. When a light reflecting surface (an object to be detected) approaches, the photoelectric device receives the reflected light and outputs a signal, so that the approaching of the object can be sensed. Above-mentioned proximity sensing switch all belongs to current ripe proximity sensing switch, adopts commercially available conventional model, can realize the utility model discloses a relevant content is not being repeated here.

In the preferred embodiment, the sensor 5 is a conventional cylindrical capacitive proximity sensor switch available in the market.

As shown in fig. 4, the fixing frame 1 includes a housing 101 having a box structure with a cavity therein and a cylindrical fixing rod 102 fixed to an outer side surface of the housing 101. The lower part of the cover body 101 is of an integral opening structure, and the side surface of the cover body is provided with a fixing hole 103. The fixing hole 103 is adapted to the external dimension of the sensor 5, for example, when the sensor 5 is a conventional cylindrical capacitive proximity sensor switch, the fixing hole 103 is a circular hole with a diameter adapted to the external diameter of the capacitive proximity sensor switch. The fixing shaft 104 has a cylindrical structure with a thread at one end and is welded to the inner sidewall of the housing 101 at the other end. The fixing shaft 104 and the fixing hole 103 are located on the same plane of the side wall of the housing 101. The cover body 101 adopts the box structure with the downward opening to carry out isolation protection on the parts inside the cavity, effectively isolates substances such as external dust, materials, water drops and the like, and prevents the influence on the deviation rectifying switch.

As shown in fig. 5, the swing link 2 includes a baffle 201, a rotating sleeve 202, a rod 203 and a weight 204; the stopper 201 has a plate-like structure having an L-shaped bend, and is fixed to the upper portion of the rotary sleeve 202 by any one of bonding, welding, and caulking. The rod body 203 is fixed at the lower part of the rotary sleeve 202, corresponds to the baffle 201, has a collinear center, and has a weight block 204 at the lower end part. The counterweight 204 can maintain the stability of the swing rod 2, so that the swing rod is in a stable static state without being influenced by external force. The material of the baffle 201 is suitable for the inductor 5. For example, when the sensor 5 is a hall proximity switch, a permanent magnet is fixed on a surface of the blocking piece 201 close to the sensor 5. When the inductor 5 adopts a capacitive proximity inductive switch, the blocking piece 201 is made of a hard material, and preferably, the blocking piece 201 is made of a stainless steel material.

When in use, as shown in fig. 6, 2 filter cloth deviation rectifying switches are symmetrically fixed on the frames 7 at two sides of the filter cloth 8 in the width direction, so that the filter cloth 8 is positioned between the two symmetrical swing rods 2, and the distance between the two deviation rectifying switches is adjusted to a proper position. After the filter cloth 8 deviates, the edge position of the filter cloth touches the swing rod 2, so that the swing rod 2 rotates around the fixed shaft 104, the baffle sheet 201 blocks the sensor 5, the sensor 5 sends out a corresponding electric signal under the blocking effect of the baffle sheet 201, and the PLC receives the corresponding electric signal and judges that the filter cloth 8 is in the deviation state.

Thus, it should be understood by those skilled in the art that while exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations and modifications can be made in accordance with the principles of the invention without departing from the spirit and scope of the invention, which is broadly defined and defined herein. Accordingly, the scope of the present invention should be understood and interpreted to cover all such other variations or modifications.
