Problems solved by technology

Existing coating machines are mainly prepared for the characteristics of existing thin films such as hot stamping films and transfer films. Using existing coating machines to coat wire-drawn films, the coating accuracy is not accurate enough, which will cause Uneven coating affects the quality of the drawing film. In addition, the structure and function of the current coating machine are too simple to ensure that the quality of the drawing film remains stable during the coating process.

Embodiment 1

[0036] A wire drawing film coating machine, comprising a controller, the controller is electrically connected to a coiling unit 1, a conveying unit 2, a coating unit 3, a drying device 4 and a winding unit 5 in sequence, and the coiling unit 1 includes a winding unit The unwinding machine base is provided with an unwinding air shaft 10 and a flattening roller for fixing the unwinding film roll on the unwinding machine base, and the flattening roller is located between the unwinding air shaft 10 and the conveying unit 2 , A deviation correcting device 13 is provided between the flattening roller and the conveying unit 2 .

[0037] Specifically, the film roll to be coated is passed into the unwinding air shaft 10, and then inflated by the inflation device, the unwinding air shaft 10 can be closely attached to the film roll, and no slippage will occur during the coating process Phenomenon, to ensure the accuracy of coating. The flattening roller is used to flatten and transport ...

Embodiment 2

[0045] The difference between this embodiment and Embodiment 1 is: the bottom of the trough 32 is provided with a feeding port, and the feeding port is connected with a feeding device, and the feeding device includes a feeding pipe, a paint storage device 38 and a transmission power mechanism Specifically, the transmission power mechanism is a delivery pump 39 , the paint storage device 38 is connected to the delivery pump 39 , and the paint is delivered to the material tank 32 through the delivery pump 39 . The prepared paint is placed in the paint storage device 38, and then the paint is delivered to the material tank 32 by the delivery pump 39. The liquid level of the paint in the material tank 32 can be adjusted at any time, and the remaining paint can be stored in the paint storage device 38 again. In the process, prevent the paint from being in contact with the air for too long and affect the quality of the paint.

[0046] The drying device 4 includes 4 drying sections....

Embodiment 3

[0052] The difference between this embodiment and the second embodiment is that: the winding unit 5 further includes a tracking and positioning device 53 located between the winding air shaft 52 and the tension control device 55 . The tracking and positioning device 53 controls the tightness of the film material during winding.

[0053] The tracking and positioning device 53 includes a tracking roller set and a sliding mechanism. The tracking roller set includes a fixed seat on which a rubber pressing roller and a passing roller are mounted, and the fixed seat is slidably connected to the sliding mechanism. The sliding mechanism is set on the unwinding base, and is equipped with a slide rail. The tracking roller group is provided with a rubber roller and a roller through the fixed seat. The film passes through the roller to reach the rubber roller and then to the winding air shaft 52. When the film material is in the process of continuous winding, the rubber roller will be clo...

Abstract

The invention belongs to the technical field of film coating equipment, and particularly relates to a wire drawing film coating machine. The wire drawing film coating machine comprises an coiling set, a conveyor set, a coating machine set, a drying device and a take-up machine set, wherein the coating machine set comprises a micro gravure coating device; the micro gravure coating machine comprises a base; a material trough is arranged above the base; a micro gravure coating roller is arranged above the material trough; a scraper device is arranged on one side of the micro gravure coating roller; a film roller lifting mechanism is arranged above the micro gravure coating roller, and is connected with a driving device; reticulate patterns which are formed by interlacing cross grains with 40 to 65 degrees is arranged on the surface of the micro gravure coating roller; and the diameter of the micro gravure coating roller is 50 to 70mm. The wire drawing film coating machine has the characteristics of high coating accuracy and good coating effect, and can be used for coating wire drawing films imitating an metal effect.

Description

technical field [0001] The invention belongs to the technical field of film coating equipment, in particular to a wire drawing film coating machine. Background technique [0002] The application of coating machine is very extensive. Coating lamination equipment is mainly used for gluing coating and lamination processing of various roll substrates such as plastic film, paper, anodized aluminum, cloth and leather. It is widely used in various packaging fields and has broad development prospects. [0003] At present, there are many types of film products on the market, such as hot stamping film, transfer film, etc., which need to be glued and inked by a coating machine. Different types of films have different requirements for coating machines. At present, a new type of film called drawing film appears on the market. Through a special drawing process, the surface of the film layer has a metal-like drawing pattern, and then it is coated and colored by a coating machine to form a...
