DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] See also Figures 1 to 5 The utility model provides an anti-static conveying device, including a conveyor belt 1, which is arranged on a conveyor belt bracket 2. The four corners of the lower end of the conveyor belt bracket 2 are connected with support columns 3, and the lower end of the support column 3 is sleeved with a rubber sleeve 4. A first conductive block 5 is arranged in the middle of the rubber sleeve 4. The thickness of the first conductive block 5 is equal to that of the rubber sleeve 4, so that the entire conveying device can remain stable.

[0023] An antistatic grounding device is installed at the lower end of the conveyor belt support 2. The antistatic grounding device includes a second conductive block 12, a first grounding column 13, a second grounding column 14, a lead screw 15, a fixing slot 16, a bearing 17, a first bevel gear 18, a second bevel gear 19, a rotating handle 20, a connecting piece 21, and a grounding wire 22. The second conductive block 12 is provided with a fixing slot 16, in which the first grounding column 13 is fixedly installed. The lower end of the first grounding column 13 is movably connected to the second grounding column 14. The lower end of the second grounding column 14 is provided with a connecting piece 21, which is used to connect the grounding wire 22. The end of the grounding wire 22 away from the connecting piece 21 is grounded. The static electricity on the wear-resistant layer 9 of the conveyor belt 1 and the static electricity generated by the friction between the conveyor belt 1 and the conveyor belt support 2 are all conducted to the ground through the antistatic grounding device and the first conductive block 5 on the support column 3. The upper end of the second grounding column 14 is threadedly connected with a lead screw 15. The end of the lead screw 15 away from the second grounding column 14 is rotatably installed in the first grounding column 13 and connected with a first bevel gear 18. A second bevel gear 19 is provided on one side of the first bevel gear 18. The first bevel gear 18 and the second bevel gear 19 are meshed with each other. The second bevel gear 19 is fixedly connected with a rotating handle 20. The inner wall of the first grounding column 13 is provided with a sliding groove, and the outer surface of the second grounding column 14 is provided with a limit block. The limit block moves up and down along the sliding groove. Through the cooperation of the limit block and the sliding groove, the second grounding column 14 can be prevented from rotating circumferentially with the lead screw 15. When in use, the rotating handle 20 is rotated, and the rotating handle 20 drives the second bevel gear 19 to rotate. The first bevel gear 18 and the second bevel gear 19 are meshed with each other. The second bevel gear 19 drives the first bevel gear 18 to rotate, and the first bevel gear 18 drives the lead screw 15 to rotate. The lead screw 15 drives the second grounding column 14 to reciprocate in the first grounding column 13, so that the length of the grounding column can be adjusted.

[0024] The conveyor belt 1 includes an antistatic layer 8 and a wear-resistant layer 9 from the outside to the inside. The inner surface of the antistatic layer 8 is connected with the wear-resistant layer 9. The antistatic layer 8 is made of PVC material, and the wear-resistant layer 9 is made of wear-resistant material. The outer surface of the antistatic layer 8 is provided with a metal block 10, and the metal block 10 is embedded in the antistatic layer 8, and the outer surface of the metal block 10 is highly consistent with the outer surface of the antistatic layer 8. At the same time, the metal block 10 is arranged perpendicular to the movement direction of the conveyor belt 1, which is convenient for placing the ternary positive electrode material. The metal block 10 extends on the outer surface of the antistatic layer 8 of the conveyor belt 1, and the two adjacent metal blocks 10 are connected. The connecting part is also exposed on the outer surface of the antistatic layer 8 of the conveyor belt 1, so that the static electricity on the ternary positive electrode material can be effectively conducted to the metal block 10. The metal block 10 is provided with a groove 11, which is used to place the ternary positive electrode material and improve the contact effect between the ternary positive electrode material and the metal block. The groove 11 is an inverted trapezoidal structure, which is convenient for placing the ternary positive electrode material and preventing the ternary positive electrode material from separating from the metal block 10. The upper end of the conveyor belt bracket 2 is connected to an electrostatic protection cover 6, and an ion fan 7 is installed on the top inner wall of the electrostatic protection cover 6. The ion fan 7 blows the surface of the conveyor belt 1 to blow away all the charges conducted in the metal block 10, thereby ensuring that the ternary positive electrode material no longer carries static electricity. At least three ion fans 7 are set to ensure that the ion fans 7 can blow to all surfaces of the conveyor belt 1. Compared with other methods of removing static electricity, the ion fan 7 has some advantages. First, it is a contactless method of eliminating static electricity and will not cause damage to objects. Secondly, the effect of the ion fan 7 is stable and reliable, and is not affected by the ambient temperature and humidity. In addition, the ion fan 7 is also energy-saving and can run for a long time without generating too much heat.

[0025] Working principle: When the anti-static conveying device is working and conveying the ternary positive electrode material, the conveyor belt 1 is started, and the conveyor belt bracket 2 is made of stainless steel. When the conveyor belt 1 is moving, the conveyor belt 1 near the conveyor belt bracket 2 is easy to transmit static electricity to the bracket, and the transmission belt 1 often produces a certain friction with the bracket during operation, and also generates some static electricity. The anti-static grounding device and the first conductive block 5 on the support column 3 can conduct the static electricity generated by the mutual friction between the bracket and the conveyor belt 1 and the static electricity on the wear-resistant layer 9 of the conveyor belt 1 into the earth, avoiding excessive static electricity on the wear-resistant layer 9 of the conveyor belt 1 and the conveyor belt bracket 2. At the same time, the ternary positive electrode material is placed in the groove 11 of the metal block 10, and the static electricity carried by the ternary positive electrode material itself will be conducted to the metal block 10. The ion fan 7 on the top of the internal cover of the electrostatic protection cover 6 blows across the surface of the conveyor belt 1 to blow away all the charges in the metal block 10, ensuring that the ternary positive electrode material no longer carries static electricity. In addition, the conveyor belt 1 is divided into an antistatic layer 8 and a wear-resistant layer 9. The antistatic layer 8 is made of PVC material, so that the antistatic layer 8 does not carry static electricity.
