[0002] Cable feeders are used to feed cables by applying appropriate tension to the cable while keeping it moving smoothly along a predetermined path.

[0003] In related technologies, after the cable is placed on the cable feeding rack, the feeding process needs to be started or stopped manually by pressing a button, which is very cumbersome and has a low degree of automation. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an automatic stop device for wire feeding, which can start or stop the wire feeding process without manually pressing a button, simplifying the operation process and making the wire feeding process more automated.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] The first aspect of this application provides an automatic line-feeding stop device, comprising: a swing assembly including a first fixed plate, a swing arm and a first gear, the swing arm being disposed on the first fixed plate and the first gear being disposed on the swing arm; and a transmission assembly including a second fixed plate, a potentiometer and a second gear, the first gear being disposed on the second fixed plate, the potentiometer being disposed on the second fixed plate and the second gear being disposed on the potentiometer, the second gear meshing with the first gear.

[0007] The swing arm includes a rotating rod, a counterweight, a support column, and a winding wheel. The counterweight is disposed at the first end of the rotating rod, the support column is disposed at the second end of the rotating rod, and the winding wheel is disposed on the support column.

Rather, these embodiments are provided to make this application more thorough and complete, and to fully convey the scope of this application to those skilled in the art.

[0023] It should be understood that although the terms "first," "second," "third," etc., may be used in this application to describe various information, this information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this application, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0024] Unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0025] Currently, after the cable is placed on the cable feeding rack, the feeding process needs to be started or stopped manually by pressing a button, which is very cumbersome and has a low degree of automation.

[0026] To address the aforementioned issues, this application provides an automatic wire feeding stop device that eliminates the need for manual button pressing to start or stop the wire feeding process, simplifying the operation and making the wire feeding process more automated.

[0027] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0028] Please see Figure 1 and Figure 2 An automatic stop device for wire feeding includes: a swing assembly 100 and a transmission assembly 200. The swing assembly 100 includes a first fixed plate 110, a swing arm 120, and a first gear 130. The swing arm 120 is disposed on the first fixed plate 110, and the first gear 130 is disposed on the swing arm 120. The transmission assembly 200 includes a second fixed plate 210, a potentiometer 220, and a second gear 230. The first gear 130 is disposed on the second fixed plate 210, the potentiometer 220 is disposed on the second fixed plate 210, and the second gear 230 is disposed on the potentiometer 220. The second gear 230 meshes with the first gear 130.

[0029] It should be noted that after the cable is attached to the swing arm 120 and power is applied, the swing arm 120 will operate automatically, adjusting the output voltage of the potentiometer 220 by swinging up and down. When the cable is finished being laid out and the swing arm 120 falls to its lowest point, the potentiometer 220 outputs 0V, at which point the laying operation automatically stops. This method allows for automatic start and stop of the laying process after power is applied, simplifying the operation and making the laying process more automated.

[0030] Please see Figure 1 In one embodiment, the swing arm 120 includes a rotating rod 121, a counterweight 122, a support column 123, and a winding wheel 124. The counterweight 122 is disposed at the first end of the rotating rod 121, the support column 123 is disposed at the second end of the rotating rod 121, and the winding wheel 124 is disposed on the support column 123.

[0031] It should be noted that by setting the counterweight 122, the rotating rod 121 can swing up and down. The rotation of the rotating rod 121, in turn, drives the winding wheel 124 to swing up and down.

[0032] Please see Figure 2 In one embodiment, the swing arm 120 further includes a linkage shaft 125 and a bearing seat 126. The rotating rod 121 is rotatably mounted on the linkage shaft 125, the linkage shaft 125 is mounted on the bearing seat 126, the bearing seat 126 is mounted on the first fixed plate 110, and the first gear 130 is rotatably mounted on the bearing seat 126.

[0033] It should be noted that the rotation of the rotating rod 121 drives the first gear 130 to rotate through the linkage shaft 125 and the bearing seat 126, and finally drives the second gear 230 to rotate, thereby changing the resistance value of the potentiometer 220 and causing the potentiometer 220 to output different voltages.

[0034] In one embodiment, the vertical distance from the second end of the rotating rod 121 to the linkage shaft 125 is greater than the vertical distance from the first end of the rotating rod 121 to the linkage shaft 125.

[0035] It should be noted that, according to the actual environment, this application can change the relationship between the vertical distance from the second end of the rotating rod 121 to the linkage shaft 125 and the vertical distance from the first end of the rotating rod 121 to the linkage shaft 125.

[0036] Please see Figure 2 In one embodiment, the swing assembly 100 further includes a first limiting block 140 and a second limiting block 150, which are respectively spaced apart on the first fixing plate 110.

[0037] It is understood that the rotating rod 121 passes between the first limiting block 140 and the second limiting block 150 to prevent the rotating rod 121 from rotating excessively.

[0038] Please see Figure 1 In one embodiment, the swing assembly 100 further includes a mounting post 160 and a weight plate 170. The mounting post 160 is disposed on the first fixing plate 110, and the weight plate 170 is disposed on the mounting post 160. The weight plate 170 has a card slot. Preferably, the diameter of the card slot is the same as the radius of the support post 123.

[0039] It should be noted that by attaching the weight plate 170 to the mounting post 160, the tension of the cable can be increased.

[0040] Please see Figure 3 In one embodiment, the automatic cable laying stop device further includes an electrical cabinet 300, which is located on one side of the first fixing plate 110. The electrical cabinet 300 is used to house the frequency converter for electrical connection with the potentiometer 220.

[0041] Please see Figure 3 In one embodiment, the automatic line-feeding stop device further includes a base 400, which is disposed on the first fixing plate 110. Specifically, it also includes a spool 500, which is disposed on the base 400.

[0042] It should be noted that the spool 500 is used for winding cables.

[0043] The mechanical principle of this application is explained below:

[0044] First, the lower limit voltage of potentiometer 220 is preset to 1V, and the initial state of rotating rod 121 is that the end with the winding wheel 124 is tilted towards the spool 500. When the cable is fed and power is applied, the end of rotating rod 121 with the winding wheel 124 moves away from the spool 500 and begins to swing back and forth vertically, thereby changing the voltage of potentiometer 220, which in turn changes the output voltage of the frequency converter. The motor driven by the frequency converter also starts to move, so that the cable begins to wind. When the cable winding is finished, the end of the winding wheel 124 moves closer to the spool 500. When rotating rod 121 stops completely, the spool 500 also stops moving. At this time, the output voltage of potentiometer 220 is 0V, the frequency converter stops outputting, and the motor driven by the frequency converter also stops rotating, and the entire device stops automatically.
