DETAILED DESCRIPTION OF THE EMBODIMENTS
[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0018] Please refer to Figures 1-3 , the present invention provides a technical solution:
[0019] A copper foil tape fixing device includes a copper foil tape body 1. An upper cover plate 2 is provided above the copper foil tape body 1, and a lower cover plate 3 is provided below the copper foil tape body 1. A lower pinch roller 5 and an upper pinch roller 4 are respectively provided at one ends of the lower cover plate 3 and the upper cover plate 2 facing the copper foil tape body 1. A docking bayonet 6 is provided at one end of the lower pinch roller 5 facing the upper pinch roller 4. A docking stud 7 is provided directly above the docking bayonet 6. An expansion disc 8 is fixedly connected to the outside of the docking stud 7. Activity square grooves 9 are respectively opened on the inner sides of the upper cover plate 2 and the lower cover plate 3. A traction block 10 is slidably connected to one side inside the activity square groove 9. A limiting rotating shaft 11 is rotatably installed on the other side inside the activity square groove 9. A coil spring 12 is hooked and connected to the outside of the limiting rotating shaft 11. A traction steel cable 13 is fixedly connected to one side of the traction block 10.
[0020] As Figure 3 shown, a plastic drum body 15 is provided inside the copper foil tape body 1. The plastic drum body 15 is coaxially arranged with the upper cover plate 2 and the lower cover plate 3 respectively. When using the entire copper foil tape body 1, the plastic drum body 15 mainly plays a role in central winding limitation to a certain extent; Outer threaded snap rings 14 are respectively fixedly connected to one ends of the upper cover plate 2 and the lower cover plate 3 close to the inside of the plastic drum body 15. The upper and lower group of the outer threaded snap rings 14 are respectively in threaded structures with the plastic drum body 15. After the upper cover plate 2 and the lower cover plate 3 are respectively threadedly connected to the plastic drum body 15 through the outer threaded snap rings 14, the setting of the group of outer threaded snap rings 14 mainly plays a role in auxiliary connection and also facilitates the convenient disassembly and assembly of the entire fixing device.
[0021] As Figure 1 、 Figure 2 and Figure 3As shown, a set of upper pinch rollers 4 is arranged in a left-right symmetric structure along the vertical central axis of the upper cover plate 2, and a set of lower pinch rollers 5 is arranged in a left-right symmetric structure along the vertical central axis of the lower cover plate 3. A set of upper pinch rollers 4 and a set of lower pinch rollers 5 are respectively pressed and attached to the copper foil tape body 1. After the set of upper pinch rollers 4 and the set of lower pinch rollers 5 are respectively pressed and attached to the copper foil tape body 1, the copper foil tape body 1 can be effectively fixed before and after use; the upper pinch roller 4 is threadedly connected to the upper part of the docking stud 7. The lower part of the docking stud 7 is provided with an external thread structure threadedly connected to the docking bayonet 6. The inner end of the docking bayonet 6 and the outer end of the docking stud 7 are arranged with matching sizes. The traction block 10 is fixedly connected to the upper pinch roller 4. The traction block 10 is elastically connected to the coil spring 12 through the traction steel rope 13. After the lower cover plate 3 and the upper cover plate 2 are respectively installed at the upper and lower ends of the plastic reel body 15, the docking stud 7 can be screwed downward by the expansion disc 8, so that the docking stud 7 can be threadedly connected to the docking bayonet 6, so that the upper pinch roller 4 and the lower pinch roller 5 can be spliced and connected together for subsequent use.
[0022] Working process: When using this double-sided copper foil tape, the leading end of the copper foil tape body 1 can be manually pulled and drawn outwards, so that the copper foil tape body 1 can squeeze and expand the left-side pinch roller assembly or the right-side pinch roller assembly to achieve unfolding and release. After cutting off the copper foil tape body 1 with a suitable size from the plastic reel body 15, it will be convenient to use the copper foil tape body 1 to assist in the bonding and installation of the copper foil subsequently. After cutting off and releasing a single section of the copper foil tape body 1 and removing the pulling force on the remaining copper foil tape body 1, under the connection and limitation of the upper cover plate 2 and the lower cover plate 3, as the copper foil tape body 1 gradually becomes shorter during use, the single-sided pinch roller assembly composed of the traction block 10, the traction steel rope 13, the upper pinch roller 4, the lower pinch roller 5, the docking bayonet 6, the docking stud 7 and the expansion disc 8 will utilize the rebound force generated by the coil spring 12 when the external force gradually decreases and move closer to the gradually shorter copper foil tape body 1, so as to facilitate the entire device to effectively fix the used copper foil tape body 1 through the extrusion of the pinch roller assembly and prevent it from being easily loosened.
[0023] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
