Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, and in particular to a lead wire device. Background Technology

[0002] In tag cord manufacturing systems employing the "particle head injection molding" process, the pull-string device is responsible for the traction, positioning, and obstacle avoidance functions of the cord segment. Its workflow typically involves pulling the cord segment out of the release area while ensuring the cord remains free of twisting.

[0003] However, traditional tensioning methods rely heavily on manual pulling, cranking, or lever hoists, resulting in high labor intensity, significant tension fluctuations, and low control precision. To improve automation, modern tensioning devices have introduced constant-force springs to replace manual labor, achieving automatic tensioning. However, spring structures are prone to fatigue during long-term use, resulting in a limited lifespan and hindering the sustained and stable operation of the equipment. Utility Model Content

[0004] To address the problems mentioned above, this utility model provides a lead wire device, which features simple structure, convenient maintenance, and long service life.

[0005] The solution adopted by this utility model to solve its technical problem is: a lead wire device, including a fixing frame, wherein the fixing frame is provided with a lead wire track and a pull wire block, and the pull wire block is located inside the lead wire track and its movement is constrained by the lead wire track;

[0006] The conductor rail has openings on both sides, through which external ropes pass into and out of the conductor rail. The pull block is used to pull the external ropes from the top of the conductor rail to the bottom of the conductor rail.

[0007] Furthermore, a sensor is provided on the side of the fixing frame to detect the state of the bottom of the conductor rail.

[0008] Furthermore, the sensor is electrically connected to an alarm device.

[0009] Furthermore, the top surface of the fixing frame is provided with a wire pushing assembly, which includes a driver and a push plate connected to the output end of the driver. The push plate is located on the side of the wire track and is used to push the external wire rope.

[0010] Furthermore, a pressure frame is rotatably connected to the side of the fixing frame near the push wire assembly.

[0011] Furthermore, the sensor includes, but is not limited to, at least one of a proximity sensor, a photoelectric sensor, a displacement sensor, or a visual recognition device.

[0012] In summary, the beneficial effects of this utility model are as follows:

[0013] 1. The pull block of this application can pull the external rope within the conductor track by its own weight, so that the rope can always remain straight and untwisted. It has a simple structure, is easy to maintain, and has a long service life.

[0014] 2. The mounting frame is equipped with a sensor that can detect the state of the bottom of the conductor rail and is electrically connected to the alarm device. When the rope breaks, the pull block will fall to the bottom of the conductor rail and be detected by the sensor, triggering the alarm to remind the operator.

[0015] 3. A pusher assembly is provided on the top surface of the fixed frame. The pusher assembly can loosen the rope on the fixed frame in advance to prepare for the next step of pulling the rope. At the same time, when the push plate presses down on the rope, it can pull the rope of the next step back to the bottom of the conductor track. In addition, the puller block pulls the rope back by gravity, but it cannot guarantee that the rope will be pulled back to the appropriate position on the conductor track. The pusher assembly can ensure that the rope is pulled back to the appropriate position on the conductor track.

[0016] The above description is merely an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this utility model more apparent and understandable, preferred embodiments are described below in detail with reference to the accompanying drawings.

[0022] To make the content of this utility model easier to understand, the present utility model will be further described below with reference to specific embodiments and accompanying drawings.

[0023] It should be noted that the terms "center," "upper," "lower," "front," "rear," "left," "right," "inner," and "outer" used herein to indicate the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Unless otherwise stated, "a plurality of" means two or more.

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

[0025] like Figures 1 to 4 As shown, a lead wire device includes a fixing frame 1, with winding rods respectively provided on both sides of the top of the fixing frame 1, such as... Figure 2 and Figure 4 As shown, the fixing frame 1 also has a guide rail 2 and a pull block 3 inside. The pull block 3 is located inside the guide rail 2 and its movement is constrained by the guide rail 2. The guide rail 2 has openings 21 on both sides, through which external ropes enter and exit the guide rail 2.

[0026] In this embodiment, the external cord is wound into the fixed frame 1 by the winding rod at the wire inlet end of the fixed frame 1, then passes through the through-hole 21 into the inside of the wire rail 2, and is straightened by the pull block 3 inside the wire rail 2. Then it passes out through the through-hole 21 near the wire outlet end of the wire rail 2, and then winds out from the winding rod on the wire outlet end side of the fixed frame 1.

[0027] like Figure 3 As shown, a sensor 4 is installed on the side of the mounting bracket 1. The sensor 4 is used to detect the state of the bottom of the conductor rail 2 and is electrically connected to an alarm device. In this embodiment, the sensor 4 is a photoelectric sensor, including a beam emitter and a receiver. The beam emitter and receiver are respectively installed on both sides of the bottom of the mounting bracket 1, facing the bottom surface of the conductor rail 2 for detection. Correspondingly, the bottom of the conductive rail in this embodiment has a perforation for the beam to pass through. When the external cable breaks, the pull block 3 will fall into the bottom of the conductor rail 2 and block the beam of the sensor 4, causing the receiver signal to be interrupted, changing the output state and triggering the alarm device to notify the operator.

[0028] Optionally, in addition to photoelectric sensor 4, sensor 4 in this embodiment can also be at least one of proximity sensor 4, displacement sensor 4, or visual recognition device.

[0029] A wire pressing frame 7 is rotatably connected to the side of the fixing frame 1 near the wire pushing assembly. The wire extends from the wire pressing frame 7 and is then pulled away by an external wire-using device. In this embodiment, the height of the wire extending from the wire pressing frame 7 can be flexibly adjusted by rotatably connecting it, allowing for use with the external wire-using device. After the external wire-using device pulls away a section of wire and the wire becomes slack, the wire pulling block 3 pulls out another section of wire from the source of the wire by its own weight, and it falls from the top of the wire guide rail 2 to the bottom of the wire guide rail 2, tightening the wire and preparing it for the next process.

[0030] like Figure 1 As shown, a pusher assembly is provided on the top surface of the mounting bracket 1. The pusher assembly includes a driver 5 and a pusher plate 6 connected to the output end of the driver 5. The pusher plate 6 is located on the side of the conductor rail 2 and is used to push the external wire rope. In this embodiment, the pusher device can pre-loosen the wire rope on the mounting bracket 1 to prepare for the wire pulling action in the next procedure. At the same time, when the pusher plate 6 presses down on the wire rope, it can pull the wire rope of the next step back to the bottom of the conductor rail 2. In addition, the wire pulling block 3 pulls the wire rope back by gravity, but it cannot guarantee that the wire rope will be pulled back to the appropriate position of the conductor rail 2. The pusher assembly can ensure that all wire ropes are pulled and pushed to the predetermined position at the bottom of the conductor rail 2.

[0031] Specifically, the end of the fixing frame 1 and the pressure frame 7 are respectively machined with corresponding connecting holes, and are connected by through-hole rotation using pins or bolts.

[0032] The embodiments described above are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and modifications made by those skilled in the art based on this utility model shall fall within the scope of protection of this utility model.
