[0042] Preferably, the antistatic adhesive tape comprises a grounding conductive assembly 10, which comprises a conductive wire 11, a conductive sheet 12, and a grounding connecting piece 13. The conductive wire 11 is sleeved on the outer periphery of the winding drum 1, the conductive sheet 12 is inserted into the side surface of the winding drum 1, and the insertion end of the conductive sheet 12 is inserted into the outer periphery of the winding drum 1 and electrically connected with the conductive wire 11. The conductive elastic member 7 wraps the conductive wire 11 and is adhered to the outer periphery of the winding drum 1. The grounding connecting piece 13 is electrically connected to the conductive sheet 12.

[0043] The installation process and the flow path of the static charge of the grounding conductive assembly 10 in this embodiment are as follows: first, the conductive wire 11 is evenly wound around the outer surface of the winding drum 1, and the position for connecting with the conductive sheet 12 is reserved. Then, the conductive sheet 12 is inserted into the pre-set slot on the side surface of the winding drum 1 until the inserted end tightly touches the conductive wire 11 to form an electrical connection. The insertion process can be assisted by a small auxiliary tool to fine-tune the connection angle and depth to ensure stable connection. After that, the special adhesive, such as glue, is evenly applied on the outer layer of the conductive wire 11 to stabilize the position of the conductive wire 11. Then, the conductive elastic member 7 is attached to wrap the conductive wire 11, which can not only stabilize the conductive wire 11 but also enable the conductive wire 11 to continuously sense the static electricity generated by the adhesive tape body 2. Finally, the grounding connector 13 is fixed on the conductive sheet 12, and the static electricity generated by the adhesive tape body and the conductive wire 11 is conducted to the conductive sheet 12. The grounding connector 13 then conducts the charges collected by the conductive sheet 12 to the ground, completes the anti-static work, and ensures that the potential of the adhesive tape body is zero.

[0044] Preferably, the grounding connector 13 can be composed of a metal rod or a metal pipe, which is directly inserted into the ground to conduct the static charges of the adhesive tape body. The length of the grounding connector 13 can also be adjusted according to the thickness of the adhesive tape body 2 to ensure that the grounding connector 13 can be grounded smoothly. In actual use, the metal rod can be disassembled and reconnected with the conductive sheet 12 when needed.

[0045] Preferably, to improve the anti-static adhesive tape, the conductive sheet 12 and the metal rod can be connected by a metal connecting wire.

[0046] Please refer to Figure 7 The anti-static adhesive tape also includes a guiding assembly 14 arranged on the winding drum 1, which is used to place the conductive wire 11 and the conductive sheet 12. The guiding assembly 14 includes a wire slot 15 and a lead hole 16.

The conductive wire 11 is placed in the wire slot 15 and led out of the lead hole 16 to be electrically connected with the conductive sheet 12.

[0047] The guiding assembly 14 also includes a mounting plate 17 fixedly arranged on the outer surface of the winding drum 1. The mounting plate 17 can also be integrally formed with the winding drum 1. The conductive sheet 12 is installed in the mounting plate 17 to stabilize the conductive sheet 12.

[0048] In the installation stage, the installer first step by step lays the conductive wire 11 along the wire groove 15, and when reaching the position of the predetermined lead hole 16, pulls up the conductive wire 11 to make the conductive wire 11 naturally pass out, in the process, a small forceps or other tools can be used for fine adjustment to ensure that the wire is not entangled or knotted. The conductive sheet 12 can be inserted into the mounting plate 17 in alignment until it is electrically connected with the conductive wire 11 led out of the lead hole 16, and the connection point can be reinforced with silver glue which is insulating and conductive to enhance reliability and ensure that the lead assembly 14 can stably perform its function for a long time and prolong the service life of the anti-static adhesive tape.

[0049] The anti-static adhesive tape further comprises an auxiliary installation assembly 21 arranged on the outer circumferential surface of the conductive elastic member 7, and the auxiliary installation assembly 21 is used to press the conductive elastic member 7.

[0050] For the embodiment without the bearing 24, when pulling the adhesive tape body 2 in use, the reel 1 will rotate, and the wire connection will be loose, the welding point will be disconnected or the contact will be poor, which will hinder the discharge of static electricity. Or the adhesive tape is unwound, and the reel 1 can be stationary, but this operation is suitable for small amount of use, and it is not convenient for large amount of use. By arranging the bearing 24, when pulling the adhesive tape body 2, only the bearing 24 rotates, and the movement state of the reel 1 is not affected, and when the bearing 24 rotates, the ball 23 and the conductive elastic member 7 are squeezed, ensuring that the static electricity is discharged from the adhesive tape body 2 to the bearing 24, the ball 23, the conductive elastic member 7 and the conductive wire 11 in turn.

[0051] Preferably, the bearing 24 can be made of polyethylene and carbon black (or other conductive material) composite material, and the conductive elastic member 7 can be made of conductive silicone rubber material. The friction coefficient between the conductive silicone rubber and the polyethylene and carbon black composite material is relatively low, which can ensure smooth rolling of the bearing 24.

[0052] The ball 23 presses the conductive elastic member 7 in the sliding groove 22, which can make the conductive elastic member 7 tightly fit the bottom of the sliding groove 22, ensuring that it will not affect the conductivity due to looseness in the working process. This tight fit also ensures good contact between the conductive elastic member 7 and the conductive wire 11, which is conducive to the conduction of static electricity.

Next, the carrier 24 loaded with the adhesive tape body 2 is aligned with the winding drum 1 and is sleeved, and the self-weight and slight rotation adjustment are used to make it stably seated and tightly pressed above the conductive elastic member 7. Through the installation process, it is ensured that the auxiliary installation assembly 21 can play a long-term and efficient role, and the service life of the anti-static adhesive tape is prolonged.

[0054] The anti-static adhesive tape also comprises a limiting assembly 18 arranged on the outer circumferential surface of the winding drum 1, and the limiting assembly 18 is used for positioning the carrier 24. Specifically, the limiting assembly 18 comprises a matching convex strip 19 and a matching groove 20, the matching convex strip 19 is protruded and attached to the outer circumferential surface of the winding drum 1, the matching convex strip 19 can be integrally formed with the winding drum 1, the matching groove 20 is recessed in the inner circumferential surface of the carrier 24, the matching convex strip 19 and the matching groove 20 are matched in shape, and the carrier 24 can be directly clamped on the matching convex strip 19.
