Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of production of coated paper, and particularly relates to a coated paper corona treatment device. BACKGROUND

[0002] The coated paper corona treatment device is a device for modifying the surface of the coated paper through high-voltage discharge, and its core function is to improve the surface energy of the coated paper and enhance the adhesion of ink, adhesive and other materials, so as to improve the process effect of printing, compounding and coating.

[0003] According to the search, the Chinese patent with the publication number CN222554246U discloses a coated paper corona treatment device, which comprises a corona machine and a cleaning mechanism. The corona machine comprises a machine body, a roller shaft and a sliding groove. The roller shaft is arranged in the machine body, and the sliding groove is formed in the top of the machine body. The cleaning mechanism is arranged on the top of the machine body and comprises a shell, a lead screw, a motor, a sliding block and a cleaning component. The lead screw is arranged in the shell, the motor is arranged at the outer end of the lead screw, the sliding block is arranged on the lead screw and passes through the sliding groove, and the cleaning component is arranged at the lower end of the sliding block. The above-mentioned scheme drives the lead screw to rotate through the motor, drives the sliding block to reciprocate through the lead screw, and synchronously drives the cleaning component to reciprocate through the sliding block. The cleaning component contacts the coated paper on the roller shaft to clean the surface of the coated paper, so as to avoid the dust adhered to the surface of the coated paper from affecting the corona effect. However, the above-mentioned scheme still has the following deficiencies in actual use:

[0004] The corona treatment ionizes air through a high-voltage electric field to generate high-energy electrons, ions and free radicals. These active particles bombard the surface of the coated paper (such as a polyethylene or polypropylene layer) to cause the molecular chain of the material to break, form polar groups (such as hydroxyl groups and carbonyl groups) and change the surface microtopography. In this process, the electron transfer efficiency of non-conductive polymer materials is different. When high-energy particles knock out electrons from the surface of the material, if the internal electrons of the material cannot be quickly supplemented (because the polymer has poor conductivity), positive charges will accumulate on the surface. On the contrary, if the electrons are bound inside the material, negative charge accumulation may occur. The static electricity on the coated paper is easy to attract dust. The dust attracted by static electricity may be embedded in the adhesive layer to form micro-bubbles or defects, thereby reducing the peeling strength and barrier performance of the composite film. The coated paper corona device proposed in the above-mentioned scheme cannot solve this problem.

[0005] Therefore, it is necessary to design a coated paper corona treatment device to solve the above-mentioned problems. SUMMARY

The inside of the water filter box 32 is fixed with a partition plate 33 provided with a plurality of through holes. The partition plate 33 is arranged with filter cotton 34. The water flow can carry away the dust attached to the surface of the water-absorbing cloth 25 in the process of flowing, thereby cleaning the water-absorbing cloth 25. Further, the water flow mixed with dust can flow into the water filter box 32 through the plurality of overflow holes 311. The water filter box 32 is provided with filter cotton 34, which filters the water flow and purifies the water flow.

[0043] The driving structure is arranged on the side of one of the mounting plates 21 and is composed of a moving part and a reset part. The moving part includes a movable rack 46. The reset part is used for controlling the position of the rack 46 in the reset process. The rack 46 is engaged with the first gear 221. The turbulence structure is arranged on the side of the water storage box 31 and is used for making the water flow in the water storage box 31 flow towards the direction of the plurality of overflow holes 311. The moving part further includes a first sliding rail 41 fixed on the side of the mounting plate 21. The first sliding rail 41 is slidably provided with a first sliding block 42. The bottom surface of the first sliding block 42 is fixed with two guide rods 43. The bottom ends of the two guide rods 43 are fixed with limit caps 44. The two guide rods 43 are slidably sleeved with a sliding plate 45. The rack 46 is connected with the sliding plate 45 through a connecting rod 461. The end of the rack 46 is fixed with a first magnetic block 462. The reset part includes a second sliding rail 51 fixed on the side of the mounting plate 21. The second sliding rail 51 is slidably provided with a second sliding block 52. The bottom surface of the second sliding block 52 is fixed with a second magnetic block 521. The second sliding block 52 is connected with the mounting plate 21 through a tension spring 53.

[0044] The turbulence-inducing structure includes a pusher plate 71 and a pusher plate 74. The pusher plate 71 is placed inside the water storage box 31. Several openings 711 are provided on the pusher plate 71. Several rotatable movable plates 712 are provided on the side of the pusher plate 71, each movable plate 712 facing one of the openings 711. The pusher plate 74 is slidably disposed on the side of the water storage box 31 (e.g., ...). Figure 4 (As shown), and the push plate 74 is provided with an inclined surface.

Figure 4 As shown), the collar 721 is connected to the fixed plate 61 by a spring 73, and the push plate 74 is connected to the water storage box 31 by a tension spring 75.

[0045] The invention also includes a filter assembly for filtering dust from water, specifically, such as... Figure 4 and Figure 11 As shown, in the initial state, under the action of the second tension spring 75, the push plate 74 is in a position away from the fixed rod 72. At this time, the push plate 74 applies tension to the rack 46 through the connecting rope 463. At this time, the end of the rack 46 meshes with the first gear 221. When the motor 22 runs, the first gear 221 can drive the rack 46 to move. When the rack 46 moves, it can pull the push plate 74 through the connecting rope 463, causing the push plate 74 to move. When the push plate 74 moves, the inclined part of the push plate 74 will squeeze the fixed rod 72, causing the fixed rod 72 to move. When the fixed rod 72 moves, it can drive the push plate 71 to move. When the first magnetic block 462 on the rack 46 moves to the position facing the second magnetic block 521, the second magnetic block 521 will attract the first magnetic block 462, so that the first magnetic block 462 and the rack 46... When the rack 46 moves upward, it will separate from the first gear 221. When the rack 46 separates from the first gear 221, the first gear 221 no longer constrains the position of the rack 46. At this time, the push plate 74 and the rack 46 will be reset under the action of the tension spring 75. During the reset process of the rack 46, the rack 46 will remain separated from the first gear 221 under the attraction of the first magnetic block 462 and the second magnetic block 521. When the second slider 52 moves to the limit position, the second magnetic block 521 can no longer move, but the rack 46 will continue to perform the reset action. At this time, the first magnetic block 462 will move with the rack 46 and separate from the second magnetic block 521. When the first magnetic block 462 separates from the second magnetic block 521, the rack 46 will fall naturally and mesh with the first gear 221 again.

[0046] Based on the above process, the first gear 221 can drive the rack 46 to move reciprocally, and the rack 46 can pull the push plate 74 to move reciprocally through the connecting rope 463 when the rack 46 moves reciprocally, and finally make the push water plate 71 move reciprocally in the inside of the water storage box 31, and the push water plate 71 can push the water flow when moving reciprocally, and the water flow can move towards the direction of the plurality of overflow holes 311, and further, as shown in Figure 10 When the push water plate 71 pushes the water flow, the plurality of movable plates 712 are attached to the push water plate 71 under the resistance of the water flow, at this time, the push water plate 71 and the plurality of movable plates 712 form a complete plate body structure together, and the water flow can be smoothly pushed, when the push water plate 71 resets, the movable plate 712 can also be flipped under the resistance of the water flow, and is far away from the opening 711, at this time, the water flow can pass through the opening 711, so as to reduce the resistance of the push water plate 71 when resetting, reduce the load fluctuation and energy loss of the motor 22, and at the same time, maintain the moderate flow of the water flow to prevent sediment from blocking, finally, the equipment life is prolonged, the operation noise is reduced and the overall energy efficiency is improved on the premise of ensuring the cleaning effect.

[0047] The specific working principle of the present application is as follows:

[0048] The surface of the coated paper is electrified and adsorbs dust after being treated by the corona device 1, and then contacts the wet and absorbent cloth 25 in the electrostatic discharge assembly between the side plate 11; the motor 22 drives the transmission belt 24 to rotate through gear transmission, drives the wet and absorbent cloth 25 attached thereto to rotate circularly, and after the bottom of the cloth is immersed in the water storage box 31 to absorb water, the water molecules are used to neutralize the surface charge of the coated paper by using the conductivity of the water molecules, and the dust is physically removed by wiping action; the squeezing plate 65 driven by the spring of the squeezing assembly squeezes out the excess water of the cloth in real time, prevents the coated paper from being too wet, and the water guide lip 651 guides the water flow to return to the water storage box 31; in the filtering assembly, the gear-rack 46 mechanism driven by the motor 22 drives the push plate 74 to move reciprocally, the inclined surface of the push plate 74 extrudes the fixed rod 72 to make the push water plate 71 move reciprocally in the water storage box 31, the movable plate 712 is attached to form a rigid plate body to efficiently push the water flow to flush the dust when pushing water, and the movable plate 712 is flipped to form a hollow structure to reduce the reverse resistance when resetting, and the water flow mixed with dust flows into the water filtering box 32 through the overflow hole 311, is purified by the filtering cotton 34, and is recycled; the whole process realizes the adaptive adjustment of the form of the push water plate 71 through mechanical linkage, reduces the energy consumption and load fluctuation of the motor 22 while ensuring the cleaning effect, and finally forms a closed-loop system of electrostatic elimination, surface dust removal and water resource recycling, which significantly improves the quality of the coated paper post-processing and production economy.

[0049] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
