Thus, by the offset arrangement, the film 0 can be prevented from being damaged, and the liquid adhering to the film can be effectively removed.

Fig. 6 is a schematic structural view of the first wiping part 3 of the embodiment of the thin film wiping apparatus of the utility model.

Referring to fig. 6, the first liquid scraping assembly 3 includes a first blade holder 31 and a first scraper 32, the first blade holder 31 is capable of moving relative to the frame 11, the first scraper 32 is mounted on the first blade holder 31, and the first scraper 32 is used for scraping off liquid adhering to the front surface of the film 0.

The first scraper 32 is integrally formed, specifically, a plate-like member, and presses the film 0 so that the edge of the lower end portion thereof is parallel to the width direction of the film 0, thereby scraping off the liquid adhering to the film 0. For ease of understanding, the first blade 32 is divided into a mounting portion 321, and a liquid scraping portion 322 protruding downward from a lower end surface of the mounting portion 321, depending on the functional division of the blade.

Fig. 8 is a schematic view of a part of a wiping mechanism of the thin film wiping apparatus.

Referring to fig. 8, in some embodiments, the middle portion of the first scraper 32 is lower than the two side portions, and the two sides of the film 0 are gradually pushed flat while the first scraper 32 scrapes the film 0, so that the surface of the film 0 is prevented from being creased or wrinkled. In addition, the structural design of the first scraper 32 with the lower middle part and the higher two side parts can guide the scraped liquid, so that the liquid can be recovered conveniently.

The shape of the first scraper 32 is not particularly limited in this embodiment, and it is understood that the shape of the first scraper 32 may be reasonably set according to the requirement of use, for example, a longitudinal section along the conveying direction of the film 0 is arc-shaped, L-like, etc.

In the actual production process, the thickness of the film at different positions in the width direction of the film is allowed to fluctuate within a reasonable range, but if the thickness of the film 0 in the width direction of the film is different, a part of the area of the first scraper 32 is not fully contacted with the film 0, and the problem that the pressing force of the first scraper 32 on the film 0 is insufficient exists, so that the front side of the film 0 is affected.

Referring to fig. 6 again, in the present embodiment, the first tool holder 31 is provided with a plurality of adjusting screw holes along the length direction thereof, the adjusting screw holes extend along the width direction of the first tool holder 31, the adjusting screw holes are penetrated with adjusting screws 72, and the length of the adjusting screws 72 is greater than the depth of the adjusting screw holes, so that the adjusting screws 72 can extend out of the adjusting screw holes and abut against the first scraper 32.

Thereby, the first scraper 32 can be divided into a plurality of areas along the length direction thereof, and the first scraper 32 and the first knife holder 31 in each area are detachably connected and fixed through the fastener 71. If the scraping effect of a certain area is not ideal, the fastener 71 in the area can be loosened first, the first scraper 32 in the area is in a position-adjustable state relative to the first tool apron 31, then the adjusting screw 72 in the area is rotated, the adjusting screw 72 extends out of the adjusting screw hole, the first scraper 32 in the area is pushed out of the adjusting screw hole for a preset distance in a direction away from the first tool apron 31 until the first scraper 32 in the area is fully contacted with the film 0, and finally the fastener 71 is tightened again, so that the first scraper 32 in the area is fixed on the first tool apron 31.

Fig. 7 is a schematic structural view of a second wiper assembly 4 of an embodiment of the thin film wiper device of the present utility model.

Referring to fig. 7, the second liquid scraping assembly 4 includes a second blade holder 41 and a second scraper 42, the second blade holder 41 is fixedly installed on the frame 11, the second scraper 42 is installed on the second blade holder 41, and the second scraper 42 is used for scraping off the liquid attached to the front surface of the film 0.

The second scraper 42 is a plate-like member having a wedge shape as a whole, specifically, a plate-like member having a lower end portion which is positioned above a lower end portion of the first scraper 32, and is configured to scrape off the liquid adhering to the film 0 by pressing the film 0 so that the lower end portion thereof is parallel to the width direction of the film 0. The second scraper 42 is provided with a plurality of mounting holes penetrating along the length direction thereof so as to be detachably connected and fixed with the second cutter seat 41 by a fastener 71.

The material of the second blade 42 is not particularly limited in this embodiment, and it is understood that the material of the blade may be appropriately set according to the characteristics of the film, for example, stainless steel having abrasion resistance or resin coated with an abrasion-resistant coating, ceramic, or the like.

The length of the second blade 42 is determined by the width of the film 0. In order to suppress abrasion of the portion of the second blade 42 that contacts both end edges of the film 0, it is preferable that the length of the second blade 42 (i.e., the length in the width direction of the film 0) is slightly longer than the width of the film 0, and that the edges of the second blade 42 that contact the film 0 be rounded. In addition, in order to suppress adhesion of scraped liquid to the surface of the second blade 42, it is preferable to apply mirror surface treatment to the liquid scraping surface (i.e., the bottom surface and the side surface close to the film) of the second blade 42.

The size, material, and the like of the second scraper 42 are not limited to those described above, as long as the liquid adhering to the film 0 can be scraped off effectively.

Referring to fig. 8 again, the second scraper 42 is lower than the two side portions, and when the second scraper 42 scrapes the film 0, two sides of the film 0 are gradually flattened, so as to avoid marks or folds on the surface of the film 0.

The shape of the second scraper 42 is not particularly limited in this embodiment, and it is understood that the shape of the second scraper 42 may be appropriately set according to the requirement of use, for example, a longitudinal section along the conveying direction of the film 0 is arc-shaped, L-like, or the like.

As described above, the thickness of the film at different positions is allowed to fluctuate within a reasonable range, but if there is a difference in the thickness of the film 0 in the width direction thereof, this may also result in insufficient contact between the partial area of the second scraper 42 and the film 0, and there is a problem that the pressing force of the second scraper 42 against the film 0 is insufficient, affecting the scraping effect against the reverse side of the film 0.

Referring to fig. 7 again, in the present embodiment, the second scraper 42 seat is provided with a plurality of adjusting screw holes along the length direction thereof, the adjusting screw holes extend in the vertical direction, and an adjusting screw 72 is penetrated in the adjusting screw holes, and the length of the adjusting screw 72 is greater than the depth of the adjusting screw 72, so that the adjusting screw 72 can extend out of the adjusting screw holes to be abutted with the second scraper 42. Therefore, the second scraper 42 can be divided into a plurality of areas along the length direction, when the scraping effect of a certain area is not ideal, the fastener 71 in the area can be loosened first, so that the second scraper 42 in the area is in a position-adjustable state relative to the second cutter holder 41, the adjusting screw 72 is rotated, the adjusting screw 72 extends out of the adjusting screw hole, the second scraper 42 in the area is pushed out upwards by a preset distance, the second scraper 42 in the area can be ensured to be fully contacted with the reverse surface of the film 0, and finally the fastener 71 is tightened again, so that the second scraper 42 in the area is fixed on the second cutter holder 41.

The angle of the first blade 32 and the second blade 42 affects the wiping effect on the film. As shown in fig. 5, the gap formed by the first blade 32 and the second blade 42 from bottom to top of the film, the angle between the film and the bottom surface of the first blade 32 is adjusted between 70 ° and 90 °, and as a specific example, the angle between the film and the side surface of the first blade 32 is adjusted between 15 ° and 25 °, and as a specific example, the angle between the film and the side surface of the first blade 32 is adjusted between 20 °, and θ1 is set to 78 °.

The angle of the second blade 42 may be set to be the same as the angle of the first blade 32, but is preferably adjusted to be different from each other, i.e., the angle formed by the film and the bottom surface of the second blade 42 is adjusted between 70 ° and 90 °, as a specific example, the angle formed by the film and the side surface of the second blade 42 is adjusted between 15 ° and 25 °, and as a specific example, the angle formed by the film and the side surface of the second blade 42 is adjusted between 80 °, and the angle formed by the film and the side surface of the second blade 42 is adjusted between 15 ° and 25 °, and as a specific example, the angle formed by the film is set to 18 °.

Thus, by reasonably setting the angles of the first scraper 32 and the second scraper 42, the film surface of the film is not damaged while the film scraping effect is ensured.

The moving mechanism 2 comprises a walking frame 27, a retainer 29 and a power mechanism, wherein the retainer 29 is arranged on the walking frame 27, the first cutter seat 31 is arranged on the retainer 29, the retainer 29 is positioned on one side of the length direction of the first cutter seat 31, and the power mechanism is in driving connection with the walking frame 27 and is used for driving the walking frame 27 to linearly move along the width direction of the first scraper 32.

The walking frame 27 is of a rectangular tubular structure, the bottom of the walking frame 27 is provided with a groove in a penetrating mode, the walking frame 27 is rotatably connected with a walking wheel 28, and part of the walking wheel 28 penetrates out of the groove and is in contact connection with the frame 11, so that the walking frame 27 can horizontally move relative to the frame 11. It should be understood that the present utility model is not limited to the above embodiments, and the manner of engagement between the traveling frame 27 and the frame 11 is not particularly limited, and for example, the manner of engagement between the slide rail and the slide groove can be exemplified.
