Description

Technical Field

[0001] The invention relates to the technical field of static electricity elimination equipment, and in particular to a surface static electricity elimination equipment for energy-saving polyester (PET) sheet production. Background Art

[0002] Polyester PET flakes, full name polyethylene terephthalate, is a white granular solid material widely used in many fields. Its scientific name is polyethylene terephthalate, referred to as PET, which is mainly made by polymerization of purified terephthalic acid (PTA) and ethylene glycol (EG). PET flakes are widely used in bottle-grade polyester (such as carbonated beverage bottles and other beverage packaging), polyester films (packaging materials, films and tapes, etc.) and polyester for chemical fibers due to their excellent physical and chemical properties and processability. PET flakes are usually milky white or light yellow, with a smooth and shiny surface. They are a highly crystalline polymer.

[0003] In the production and use of polyester PET sheets, static electricity is a challenge that cannot be ignored. The generation of static electricity mainly comes from physical processes such as friction, contact separation or induction between materials. During the processing, transportation and use of PET film, static electricity is easily generated on the surface due to friction. The accumulation of static electricity will not only cause film adhesion and contamination, but may also cause quality problems such as poor adhesion and mottling, seriously affecting the appearance and performance of the product. In addition, static electricity may also attract dust particles in the air, further aggravating the pollution problem and reducing the product qualification rate.

[0048] In this embodiment, after the position and height adjustment of the plurality of ion wind rods 23 is completed, the produced PET sheet is then passed through the gap between the two roller bodies 33, and then one side of the PET sheet is passed through the plurality of rollers 243 in turn, and then the PET sheet is passed through the gap between the two roller bodies 33 on the other side, and then the material receiving rod needs to be connected to the second connecting block 437, and by energizing the electromagnet 4361, the electromagnet 4361 will generate a magnetic force, and then under the action of the magnetic force, the connecting block 437 will be driven to move toward the direction of the electromagnet 4361, and then the material receiving rod is placed in the inner cavity position of the two connecting blocks 437, and then by de-energizing the electromagnet 4361, the elastic force of the plurality of springs 4363 will push the connecting block 437 to move away from the propulsion assembly 436, and then under the action of the two connecting blocks 437, the position of the material receiving rod will be limited;

[0050] Example 4

[0051] like Figure 5 , Figure 6 , Fig.10 As shown, on the basis of Example 3, the present invention provides a technical solution: preferably, the drainage component 24 includes a frame 241, the frame 241 is fixedly connected to a plurality of ion wind rods 23, the frame 241 is rotatably connected to a plurality of drainage plates 242 on the side away from the ion wind rods 23, the frame 241 is rotatably connected to a plurality of rollers 243 on the side away from the ion wind rods 23, the pressure roller assembly 3 includes two support plates 31, the lower ends of the two support plates 31 are fixedly connected to the upper end of the bottom plate 1, the opposite surfaces of the two support plates 31 are rotatably connected to two roller shafts 32, the contact position between the roller shaft 32 and the support plate 31 is provided with a rough surface, and the inner cavity of the support plate 31 is provided with a rough surface, the middle part of the outer surface of the roller shaft 32 is fixedly connected to a roller body 33, the dust collecting component 5 includes a storage box 51, the lower end of the storage box 51 is fixedly connected to the upper end of the bottom plate 1, the side of the storage box 51 away from the static electricity removal structure 2 is fixedly connected to a filter screen plate 52, and the lower part of the storage box 51 is slidably connected to a dust collecting box 53.

[0052] In this embodiment, the guide plate 242 is rotated to adjust the placement angle of the guide plate 242, so that the guide plate 242 is used to guide the airflow ejected by the ion wind rod 23 to blow toward the surface of the PET sheet, and then the controller controls the operation of a plurality of ion wind rods 23. Under the action of a plurality of guide plates 242, the airflow is guided to blow toward the surface of the PET sheet, and then the ions in the airflow are used to eliminate the static electricity on the surface of the PET sheet. Since the contact position between the roller 32 and the support plate 31 is provided with a rough surface, and the inner cavity of the support plate 31 is provided with a rough surface, A rough surface is provided so that when the roller 32 rotates, the roller 32 can continuously vibrate, and then the roller body 33 can be driven to vibrate. When the roller body 33 presses the PET sheet, the sheet can be driven to vibrate, and then the dust and the like falling on the sheet can be driven to vibrate together. Then, under the action of the airflow ejected by the ion wind rod 23, the dust and the like falling on the sheet can be blown into the inner cavity of the storage box 51, and then the dust can be filtered and intercepted by the filter plate 52, and then the dust and the like can be collected by the dust collecting box 53.

[0053] The following is a detailed description of the working principle of this energy-saving surface static elimination equipment for the production of PET sheets.

[0054] like Figure 1-10 As shown, when the surface of the PET sheet needs to be electrostatically eliminated, the position height of the plurality of ion wind rods 23 needs to be adjusted first, the electric push rod 212 needs to be controlled by the controller to operate, and then the telescopic rod of the electric push rod 212 is used to drive the connecting frame 22 to be lifted and lowered, and then the support rod 213 is used to limit the moving position of the connecting frame 22 during the lifting and lowering process of the connecting frame 22 to prevent the connecting frame 22 from being offset during the lifting and lowering process;

[0055] After the position and height adjustment of the plurality of ion wind rods 23 is completed, the produced PET sheet is then passed through the gap between the two roller bodies 33, and then one side of the PET sheet is passed through between the plurality of rollers 243 in turn, and then the PET sheet is passed through the gap between the two roller bodies 33 on the other side, and then the material receiving rod needs to be connected to the second connecting block 437, and the electromagnet 4361 is energized, and then the electromagnet 4361 will generate a magnetic force, and then under the action of the magnetic force, the connecting block 437 will be driven to move toward the direction of the electromagnet 4361, and then the material receiving rod is placed in the inner cavity position of the two connecting blocks 437, and then the electromagnet 4361 is powered off, and then under the action of the elastic force of the plurality of springs 4363, the connecting block 437 will be pushed to move away from the propulsion assembly 436, and then under the action of the two connecting blocks 437, the position of the material receiving rod will be limited;

[0056] Then, the PET sheet is connected to the material receiving rod, and the worm 434 is driven to rotate by the motor, and then the worm 434 can be used to mesh with the adjacent worm wheel 433, thereby driving the worm wheel 433 to rotate, and then the worm wheel 433 can be used to drive the connecting rod 435 to rotate. Since one end of the connecting rod 435 is fixedly connected to the electromagnet 4361, when the connecting rod 435 rotates, the electromagnet 4361 is driven to rotate, and then the connecting block 2 437 can be driven to rotate during the rotation process through the plurality of guide rods 4362, so that the material receiving rod can be driven to rotate through the connecting block 2 437, so that it is convenient to roll up the PET sheet;

[0057] Then, by rotating the guide plate 242 and adjusting the placement angle of the guide plate 242, the guide plate 242 is used to guide the airflow ejected by the ion wind rod 23 to blow toward the surface of the PET sheet. Then, the controller controls the operation of a plurality of ion wind rods 23. Under the action of a plurality of guide plates 242, the airflow is guided to blow toward the surface of the PET sheet, and then the ions in the airflow are used to eliminate the static electricity on the surface of the PET sheet. Since the contact position between the roller 32 and the support plate 31 is provided with a rough surface, and a rough surface is provided in the inner cavity of the support plate 31, The rough surface can make the roller 32 vibrate continuously when the roller 32 rotates, and then drive the roller body 33 to vibrate. When the roller body 33 presses the PET sheet, the sheet will be vibrated, and then the dust on the sheet will be shaken together. Then, under the action of the airflow ejected by the ion wind rod 23, the dust on the sheet will be blown into the inner cavity of the storage box 51, and then the dust will be filtered and intercepted by the filter plate 52, and then the dust can be collected by the dust collecting box 53.

[0058] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
