Embodiment 1

[0018] Such as Figure 1-Figure 3 As shown, during the packaging process of polyester chips, a pipeline static eliminator is installed on the upper end of the feeding pipe to eliminate the static electricity generated by the friction between polyester chips and the pipe during feeding. The box opens the static eliminator, and the charged ions generated by the static eliminator neutralize the charged material ions to eliminate the static electricity carried by the material, thereby avoiding the occurrence of electrostatic discharge of the material. In addition, 4 surface static eliminators are installed around the packaging bag. The angle between the two adjacent surface static eliminators and the center of the pipeline static eliminator is 90°. The surface static eliminator is coaxial and parallel to the packaging bag. To eliminate static electricity on the surface of the packaging bag. At the same time, an electrostatic measuring instrument is installed at the operating plat...

Embodiment 2

[0021] According to the conditions described in Example 1, only 2 pipeline static eliminators are installed at the upper end of the feeding pipe, 6 surface static eliminators are arranged around the packaging bag, and the two adjacent surface static eliminators and the center of the pipeline static eliminator The connecting angle is 60°. It can also solve the electrostatic shock problem of operators in the polyester chip packaging process, and prevent fire accidents caused by static electricity.

Embodiment 3

[0023] According to the conditions described in Example 1, only 2 pipeline static eliminators are installed at the upper end of the feeding pipe, 12 surface static eliminators are arranged around the packaging bag, and the two adjacent surface static eliminators and the center of the pipeline static eliminator The connecting angle is 30°. It can also solve the electrostatic shock problem of operators in the polyester chip packaging process, and prevent fire accidents caused by static electricity.

Abstract

The invention relates to a method for static measurement and elimination during polyester chip packaging operation, and aims at mainly solving the safety problems that static sparking is likely to occur and operators are likely to suffer from electric shock in the prior art. By adopting the method for the static measurement and elimination during the polyester chip packaging operation, static caused by polyester chips and a packaging bag can be measured and eliminated. According to the technical scheme, a static measurement and elimination device includes a pipeline static eliminating device,a surface static eliminating device, a static measurement device and a PLC control cabinet, wherein the pipeline static eliminating device is installed on the upper end of a packaging blanking pipe ofthe polyester chips and used for eliminating the static carried by the polyester chips or generated during conveying of the polyester chips; the surface static eliminating device is installed on theperiphery of the packaging bag and used for eliminating the static on the surface of the packaging bag; the static measurement device is arranged on a packaging machine operation platform and used formeasuring the voltage of the static on the surface of the packaging bag; operators use the PLC control cabinet to control the implementation of the method for the static measurement and elimination during the polyester chip packaging operation. The method can well solve the problems above, and is applicable to the static measurement and elimination during the polyester chip packaging operation.

Description

technical field [0001] The invention relates to a method for measuring and eliminating static electricity in packing operation of polyester chips. technical background [0002] At present, none of the existing polyester (PET) device polyester chip balers is equipped with static elimination facilities, and most of the polyester chip balers are manually bagged. During manual operations, static ignition of the packaging bags often occurs and the operator is injured. In the event of electric shock, the above situation will not only affect the normal packaging operation, but also cause fire and personal injury accidents. The main reason for the electrostatic ignition of the packaging bag is: when the polyester chips are packed, the polyester chips enter the packaging bag along the discharge pipe in the hopper. During this process, the polyester chips will generate static electricity due to friction, and the charged material enters the packaging bag. The potential can reach more ...
