Embodiment 1

[0030] as attached figure 2 As shown, it is a schematic diagram of the front view of a coating equipment using a coating blade protection device in this embodiment; the shape of the scraper in this embodiment is a cylindrical shape with a gap.

[0031] The coating equipment of the present embodiment comprises a support roll 1 and a first scraper 2, wherein the support roll 1 is positioned below the first scraper 2, and the coating material 5 passes through the coating gap between the first scraper 2 and the support roll 1 , so that the scraper coats the coating material; the coating equipment of the present embodiment also includes a coating tank 4 and a coating tank baffle plate 3, and the coating tank 4 is positioned at the coating material 5. At the entrance, the paint tank 4 is used to hold the paint, and the paint tank baffle plate 3 is used to prevent the paint from overflowing.

[0032] The coating equipment in this embodiment also includes a coating blade protection ...

Embodiment 2

[0042] as attached Figure 4 As shown, it is a schematic diagram of the front view of a coating equipment applying a coating blade protection device in this embodiment. The difference from Embodiment 1 is that the end of the second scraper 8 in this embodiment is used for coating The cross section is a symmetrical and sharp structure. The coating scraper protection device 7 of this embodiment includes a backing film 71, a winding shaft 72, an unwinding shaft 73 and a reel fixing part. The reel fixing part of this embodiment is arranged at both ends of the second scraper 8 The reel fixing plate 74 of the present embodiment is different from the first embodiment in that the fixing position of the reel fixing plate 74 of the present embodiment is different on the scraper, and the reel fixing plate of the present embodiment is fixed near the second scraper 8 for coating The position of the reel fixing plate 74 on the second scraper 8 is set reasonably.

Embodiment 3

[0044] as attached Figure 5 As shown, it is a schematic diagram of the front view structure of a coating scraper protection device in this embodiment. The pad film fixing part and the reel fixing plate 74 in this embodiment are a combination of Embodiment 1 and Embodiment 2. In addition, Others are the same as Embodiment 1 and Embodiment 2, and only the differences are described as follows: the setting of the film fixing part in this embodiment is the same as that of Embodiment 1; the fixing method of the reel fixing plate 74 is the same as that of Embodiment 2.

[0045] From the description of Embodiment 1, Embodiment 2 or / and Embodiment 3, it can be seen that the present invention does not limit the shape of the scraper. Image 6 And attached Figure 7 In other embodiments, the coating blade protection device proposed by the present invention can be realized by rationally setting the pad film fixing part and the reel fixing part.

Abstract

The invention provides a coating scraper protection device. The coating scraper protection device is applied to coating equipment. The coating equipment comprises a scraper and a support roll. A coating material passes through a coating gap formed between the scraper and the support roll so that the coating material can be applied through the scraper. The coating scraper protection device furthercomprises a cushion film and a cushion film fixing structure. The cushion film penetrates the coating gap and wraps the outer wall of the scraper. The cushion film fixing structure is used for attaching the cushion film to the outer wall of the scraper in a wrapping manner. By means of the coating scraper protection device, the coating precision cannot be influenced; the solid foundation is provided for continuous stable production; and in addition, the coating scraper protection device has the advantages of being convenient to use, simple in structure, reasonable in arrangement and low in production cost.

Description

technical field [0001] The invention relates to the field of printing and packaging, in particular to a coating scraper protection device. Background technique [0002] as attached figure 1 As shown, at present, the coating first scraper 2 directly corresponds to the coating 4, and the coating can be all types of self-adhesive glue or other non-adhesive coatings coated with a scraper. During the coating process, some coatings follow the coating. Over time, it is easy to dry out at the edge of the scraper or have foreign matter blocked at the edge of the scraper, resulting in uneven coating on the surface of the coating film and affecting the yield of the coated product. [0003] The coating is blocked at the scraper edge, which is quite difficult to handle; since the amount of coating depends on the coating gap between the scraper and the support roller to achieve the size of the coating amount, if there is foreign matter at the scraper edge, it is necessary to open the scr...
