Description

Technical Field

[0001] The utility model relates to the technical field of induction rods, in particular to a proximity switch buffer type induction rod. Background Art

[0002] Proximity switches are widely used in equipment in modern factories. They control the operation of equipment by the gain or loss of signals. There are a large number of proximity switches on balers, among which the signal to prevent excessive withdrawal of the baling line is one of them. It plays a key role in the normal operation of the baler. Usually, the signal is always on, indicating that the baling line is in the line track. When the baling line is withdrawn excessively, the wire pressing wheel drops, the sensor rod and the proximity switch are pulled apart, and the proximity switch signal light goes out. At this time, the system will stop the rotation of the wire feeder in time to prevent the baling line from being pulled out of the baling machine.

[0003] When the existing baling line is blocked while moving forward, the baling line will be arched due to the rotation of the wire feeding reel, causing the sensor rod to suddenly hit the proximity switch, resulting in damage to the proximity switch or position change, causing the baler signal to be wrong and unable to baler normally. For this reason, we propose a proximity switch buffer sensor rod. Utility Model Content

[0004] The utility model aims to provide a proximity switch buffering induction rod to solve the problem in the above background technology that when the existing baling line is blocked while moving forward, the baling line is arched due to the rotation of the wire feeding reel, causing the induction rod to suddenly hit the proximity switch, resulting in damage to the proximity switch or change of position, so that the baling machine signal error cannot be normally baled.

[0005] To achieve the above object, the utility model provides the following technical solution: a proximity switch buffer sensor rod, comprising:

[0006] A positioning frame, wherein a horizontal plate is connected to the middle of one side of the positioning frame, and a support column is installed inside the horizontal plate, a cavity is provided inside the support column, and a sensing rod body is installed in the cavity, a switch body is installed inside the upper part of the positioning frame, and a telescopic spring is connected below the sensing rod body;

[0007] A wire pressing wheel is installed below the support column, a wire drum is installed on one side of the wire pressing wheel, bolts are installed at both ends of the sensing rod body, and a card slot is provided at the connection between the sensing bolt and the support column.

[0008] Preferably, the positions of the wire drum and the wire pressing wheel correspond to each other, and the support column runs through the interior of the horizontal plate.

[0009] Preferably, the size of the sensing rod body matches that of the cavity, and the sensing rod body is slidably connected to the support column through the cavity.

[0010] Preferably, the position of the sensing rod body corresponds to that of the switch body, and the sensing rod body forms an elastic telescopic structure with the cavity through a telescopic spring, and the sensing rod body forms a snap-fit ​​sliding structure with the slot through a bolt.

[0011] Preferably, the support column is further provided with:

[0012] Positioning rods are installed on both sides above the supporting column, and telescopic rods are installed on the inner side of the positioning rods.

[0013] Preferably, a telescopic structure is formed between the telescopic rod and the positioning rod, and the positioning rod is symmetrically distributed about the vertical center line of the support column.

[0014] Compared with the prior art, the utility model provides a proximity switch buffer type sensing rod, which has the following beneficial effects:

[0015] The utility model can make the sensing rod body close to the position of the switch body, thereby playing a key role in the normal operation of the baling machine. When the sensing rod body suddenly moves upward, the telescopic spring can be retracted into the cavity in time without causing damage to the switch body. This avoids the problem that when the existing baling line is blocked during forward movement, the baling line is arched due to the rotation of the wire feeding reel, causing the sensing rod to suddenly hit the proximity switch, resulting in damage to the proximity switch or change of position, and causing the baling machine to have signal errors and fail to baling normally.
