Description

Technical Field

[0001] This utility model relates to the field of release film processing, specifically a pretreatment mechanism for PET release film before spraying. Background Technology

[0002] Release film refers to a film with a distinct surface. When in contact with a specific material under limited conditions, the release film is not sticky or only slightly sticky. PET (polyethylene terephthalate) release film is a commonly used material in heat transfer printing. The substrate is PET, which is coated with silicone oil, so it is also called silicone oil film. Therefore, it is necessary to ensure that the surface of the release film has as little dust as possible before spraying the oil.

[0003] However, most release films on the market currently use rollers on the top and bottom of the film to remove dust before spraying. The dust is easily re-adsorbed when the release film continues to move after wiping. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a pretreatment mechanism for PET release film before spraying, which solves the problems mentioned in the background.

[0005] This utility model provides the following technical solution: a pretreatment mechanism for PET release film before spraying, including a dust removal mechanism. The dust removal mechanism has a dust scraping mechanism inside, comprising: a swing frame and a roller. A brush is sleeved on the outer side of the roller. An elastic rotating shaft connects the swing frame and the dust removal mechanism. One end of the elastic rotating shaft passes through the dust removal mechanism and is connected to an extension rod. An electrostatic dust collection chamber plate is installed on one side of the dust scraping mechanism inside the dust removal mechanism. A controller is installed on the upper surface of the dust removal mechanism corresponding to the position of the electrostatic dust collection chamber plate. A power-conducting wire connects the controller and the electrostatic dust collection chamber plate. A blower is installed on the side of the dust removal mechanism away from the dust scraping mechanism.

[0006] As a further embodiment of this utility model: a dust collection chamber is installed on the lower surface of the dust removal mechanism corresponding to the position of the electrostatic dust collection chamber plate, and a feed hole is opened on the side end of the dust removal mechanism near the dust scraping mechanism.

[0007] As a further embodiment of this utility model: a material roller is installed on the outer end of the feed hole, and a discharge hole is opened below the blower at the end of the dust removal mechanism.

[0008] As a further embodiment of this utility model: the swing frame is rotatably connected to the dust removal mechanism via the elastic rotating shaft, and the extension connecting rod is fixedly connected to the elastic rotating shaft.

[0009] As a further embodiment of this utility model: both the discharge hole and the inlet hole are connected to the dust removal mechanism, and the inner diameter of the discharge hole is smaller than that of the inlet hole.

[0010] As a further improvement of this invention, the dust collection chamber is filled with an adsorption solution.

[0011] As a further improvement of this utility model, the electrostatic dust collection chamber plate is electrically connected to the controller via the energized wire.

[0012] As a further improvement of this invention, the controller is electrically connected to the blower.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The elastic rotating shaft controls the swing frame to swing, and after the release film passes through the two rollers, the release film is pulled out from the discharge hole. As the release film moves, it is rubbed by the brush to remove the dust adsorbed on the surface.

[0015] The blower will draw dust towards the side closest to the feed port. Dust in the upper position will be adsorbed by the electrostatic dust collection chamber plate, while dust in the lower position will fall into the dust collection chamber under gravity after being adsorbed. This can prevent the subsequent application of adhesive to the release film from affecting the molding process. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1-5 As shown, this embodiment provides a pretreatment mechanism for PET release film before spraying, including a dust removal mechanism 1. The dust removal mechanism 1 has a dust scraping mechanism 10 inside. The dust scraping mechanism 10 includes: a swing frame 1001, a roller 1003, and a brush 1004 sleeved on the outer side of the roller 1003. An elastic rotating shaft 1002 connects the swing frame 1001 and the dust removal mechanism 1. The swing frame 1001 is rotatably connected to the dust removal mechanism 1 via the elastic rotating shaft 1002. One end of the elastic rotating shaft 1002 passes through the dust removal mechanism 1 and is connected to... An extension link 11 is fixedly connected to an elastic rotating shaft 1002. An electrostatic dust collection plate 8 is installed on one side of the dust removal mechanism 10 inside the dust removal mechanism 1. The electrostatic dust collection plate 8 is electrically connected to the controller 2 through a power-conducting wire 3. The controller 2 is installed on the upper surface of the dust removal mechanism 1 at the position corresponding to the electrostatic dust collection plate 8. A power-conducting wire 3 is connected between the controller 2 and the electrostatic dust collection plate 8. A blower 4 is installed on the side of the dust removal mechanism 1 away from the dust removal mechanism 10. The controller 2 is electrically connected to the blower 4.

[0024] like Figure 2-3 As shown, in this embodiment, a dust collection chamber 9 is installed on the lower surface of the dust removal mechanism 1 at the position corresponding to the electrostatic dust collection chamber plate 8. The dust collection chamber 9 is filled with an adsorption solution. A feed hole 7 is opened on the side end of the dust removal mechanism 1 near the dust scraping mechanism 10. A material roller 6 is installed on the outer end of the feed hole 7. A discharge hole 5 is opened at the end of the dust removal mechanism 1 below the blower 4. Both the discharge hole 5 and the feed hole 7 are connected to the dust removal mechanism 1. The inner diameter of the discharge hole 5 is smaller than that of the feed hole 7.

[0025] The working principle of this utility model is as follows: During use, the release film on the feed roller 6 is pulled out and inserted into the dust removal mechanism 1 through the feed hole 7. The extension connecting rod 11 applies torque, controlling the elastic rotating shaft 1002 to swing the swing frame 1001. After the release film passes through the roller 1003 between the two swing frames 1001, under the action of the elastic rotating shaft 1002, the brush 1004 on the outside of the roller 1003 will press against the upper and lower parts of the release film, preventing it from falling. Then, the release film is discharged from the outlet hole 5. After the release film is inserted, it is pulled. During operation, the electrostatic dust collection plate 8 and the blower 4 are controlled synchronously by the controller 2. When the release film moves as a whole, the dust adsorbed on the surface is wiped off by the friction of the brush 1004. The blower 4 will attract the dust to the side closer to the feed hole 7. The dust in the upper position will be adsorbed by the electrostatic dust collection plate 8 as a whole, and the dust in the lower position will fall into the dust collection chamber 9 under the action of gravity after being adsorbed. Therefore, it can prevent the subsequent coating of adhesive on the release film from affecting the molding.
