[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] See also Figures 1 to 3 The utility model provides a technical solution: a LED power line processing and cutting device, including a base 1, a cutting knife 2 and an LED line body 7. The LED line body 7 is an LED power line. The LED power line is thin and easy to bend and sag when held by hand. The LED power line needs to be wound during the processing process. After the winding is completed, the reel needs to be changed and the winding needs to be continued. During this process, the LED power line needs to be cut to facilitate winding and connection with the next reel.

[0023] In the present technical scheme, a vertical groove wheel 3 is arranged on the top of the base 1, and a cutting groove 102 connecting the wheel groove of the groove wheel 3 is opened on the outer peripheral wall of the vertical groove wheel 3, and the cutting groove 102 is the part where the LED wire body 7 is cut. A guide tube 4 is arranged on one side of the vertical groove wheel 3, and the axis of the guide tube 4 is coaxial with the tangent of the top of the wheel groove of the vertical groove wheel 3, and the function of the guide tube 4 is to lead the wire. A reversing wheel 5 located on the other side of the vertical groove wheel 3 and a wire pressing wheel 6 close to the top of the vertical groove wheel 3 are arranged on the base 1, and the wire pressing wheel 6 elastically squeezes the wheel groove of the vertical groove wheel 3, and the function of the wire pressing wheel 6 is to flexibly squeeze the LED wire body 7 into the wheel groove of the vertical groove wheel 3. In specific implementation, it is preferred that a rubber ring 61 is fixedly sleeved on the outer peripheral wall of the wire pressing wheel 6, and the function of the rubber ring 61 is to increase the friction between the LED wire body 7 and the wire pressing wheel 6 and the vertical groove wheel 3.

[0024] When in use, the LED wire body 7 passes around the reversing wheel 5 and enters the wheel groove of the vertical groove wheel 3, and then passes through the wire pressing wheel 6 and enters the guide tube 4. When the vertical groove wheel 3 rotates, the LED wire body 7 will continue to move and release.

[0025] Furthermore, a lifting rod 8 is provided on the top of the vertical groove wheel 3. In specific implementation, a portal frame can be welded on the top of the base 1, and then the lifting rod 8 is installed on the top of the portal frame. The lifting rod 8 can be an electric telescopic rod or a cylinder. The bottom of the lifting rod 8 is fixedly connected to the cutting knife 2. The function of the lifting rod 8 is to control the up and down movement of the cutting knife 2. When the cutting groove 102 is located directly below the cutting knife 2, the LED wire 7 can be cut by controlling the cutting knife 2 to descend into the cutting groove 102. After the cutting knife 2 is retracted, due to the squeezing effect of the wire pressing wheel 6, the remaining part of the LED wire 7 after being cut off will not sag or bend excessively. At this time, when the vertical groove wheel 3 rotates, the cut end of the LED wire 7 can be introduced into the guide tube 4 and then transmitted.

[0026] One side of the above-mentioned portal frame is fixedly connected to the outer peripheral wall of the guide tube 4 through a suspension rod.

[0027] In this embodiment, the outer wall of the reversing wheel 5 and the outer wall of the vertical groove wheel 3 are meshed and matched. In specific implementation, mutually meshing teeth can be provided on the outer walls of the reversing wheel 5 and the vertical groove wheel 3. This arrangement reduces the probability of slipping during transmission of the LED line 7.

[0028] Furthermore, a support plate 11 is fixedly provided on the top of the base 1, a positioning shaft 51 having one end rotatably connected to the support plate 11 is fixedly provided in the middle of the reversing wheel 5, a driving motor 101 is fixedly connected to one side of the support plate 11, an output shaft of the driving motor 101 is fixedly connected to one end of the positioning shaft 51, the driving motor 101 provides a rotational driving force to the reversing wheel 5, and the reversing wheel 5 provides a rotational driving force to the vertical groove wheel 3. It should be noted that the above-mentioned pressing wheel 6 is also rotatably connected to one side of the support plate 11.

[0029] In this embodiment, one end of the guide tube 4 is fixedly connected to a guide plate 41 located at the bottom and one end of which extends into the groove of the vertical groove wheel 3. The guide plate 41 serves to prevent the free end of the LED line 7 from sagging and guide it into the guide tube 4.

[0030] In this embodiment, the vertical groove wheel 3 includes a wheel rim 31 and a wheel sleeve 32. The outer peripheral wall of the wheel sleeve 32 is fixedly connected to the inner peripheral wall of the wheel rim 31 through a support plate 321. When in use, the wheel sleeve 32 can be rotatably connected to the above-mentioned portal frame.

[0031] Furthermore, the cross-section of the groove of the groove wheel 3 is U-shaped, and this arrangement can further increase the friction after the groove wheel 3 and the LED wire body 7 come into contact. The groove 102 is arranged to pass through the wheel rim 31, and this arrangement can avoid the problem of clogging of the groove 102. That is, when cutting, the insulation skin that falls off on the LED wire body 7 will pass through the groove 102 and fall off.

[0032] Working principle: When in use, one end of the LED wire body 7 on the pay-off roller is passed around the reversing wheel 5 and enters the wheel groove of the vertical groove wheel 3, and then passes through the wire pressing wheel 6 and enters the guide tube 4. The LED wire body 7 in the guide tube 4 is in a straight state. The LED wire body 7 led out of the guide tube 4 is connected to the external reel, and the reel is controlled to rotate. At the same time, the drive motor 101 is started. At this time, the reversing wheel 5, the wire pressing wheel 6 and the vertical groove wheel 3 are all rotated to assist in pulling the LED wire body 7. The reel winds the LED wire body 7. When the reel is wound, the cutting groove 102 is controlled to be at the highest point, and then the lifting rod 8 is controlled to move, and the cutting knife 2 descends and enters the cutting groove 102. At this time, the LED wire body 7 is cut, and then the cutting knife 2 is withdrawn. After the reel is replaced, the reversing wheel 5 is controlled to rotate, and the free end of the LED wire body 7 near the cutting groove 102 enters the guide tube 4 and approaches the reel under the guidance of the small hole in the guide tube 4. At this time, the function of automatic transmission of the LED wire body 7 after cutting is realized.

[0033] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
