Description

Technical Field

[0001] This utility model relates to the field of plastic film processing technology, specifically to a plastic film coating equipment. Background Technology

[0002] Plastic film is a thin film made of polyvinyl chloride, polyethylene, polypropylene, polystyrene and other resins. It is used for packaging and as a coating layer. With social progress, continuous technological advancement and increasing market demands for plastic film products, the quality requirements for plastic film are becoming more stringent.

[0003] Currently, many plastic film manufacturers produce finished products directly after the plastic film is completed. Such products have a short service life. There is an urgent need to improve the quality and service life of plastic films. One way to do this is to treat the surface of the plastic film and coat it with new materials to give it different properties and meet market demands. Currently, coating equipment is used to coat the surface of plastic films with new materials.

[0004] Current coating equipment directly sprays the solution of new materials onto the surface of plastic film through a nozzle when coating the plastic film with new materials. However, the direct spraying method is prone to uneven coating.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0006] The purpose of this invention is to provide a plastic film coating device that can effectively solve the above-mentioned technical problems.

[0007] To achieve the purpose of this utility model, the following technical solution is adopted: A plastic film coating device includes: a base; a coating box fixedly installed on the base; a conveyor belt installed inside the coating box; and a coating mechanism for coating the plastic film. The coating mechanism includes: a storage tank; a pump body and a cylinder fixedly installed on the coating tank; a mounting frame fixedly installed on the movable end of the cylinder; a roller brush rotatably installed in the mounting frame; a storage tube fixedly installed in the mounting frame; and a limiting rod for limiting the position of the mounting frame.

[0008] Furthermore, the coating mechanism also includes: a heating box fixedly installed on the coating box; an electric heater fixedly installed inside the heating box; and a storage box inserted into the heating box.

[0009] Furthermore, the coating mechanism also includes a stirring assembly for stirring the novel material in the storage tank; The stirring assembly includes: a reciprocating lead screw rotatably mounted on the storage tank; a motor that drives the reciprocating lead screw to rotate; a movable plate threadedly connected to the reciprocating lead screw; and a limiting strip that limits the movement of the movable plate.

[0010] Furthermore, the stirring assembly also includes: a stirring plate rotatably mounted on the movable plate; a connecting gear coaxially connected to the stirring plate; a mounting groove formed on the limiting strip; and a rack fixedly mounted in the mounting groove; wherein the connecting gear and the rack are meshed with each other.

[0011] Furthermore, a stirring blade is fixedly installed on the reciprocating screw.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This utility model discloses a plastic film coating equipment. Through the setting of the coating mechanism, when the plastic film moves with the conveyor belt, it can drive the roller brush to rotate. Through the rotation of the roller brush, the new material can be evenly coated on the surface of the plastic film, which improves the coating effect of the plastic film and avoids the uneven coating that is easy to occur when applying new materials to the surface of plastic film by direct spraying.

[0021] like Figures 1 to 4 As shown, the present invention provides a plastic film coating equipment, comprising: a base 1; a coating box 2 fixedly installed on the base 1, the coating box 2 having symmetrical material feeding openings; a conveyor belt 5 installed inside the coating box 2; and a coating mechanism for coating the plastic film.

[0022] The coating mechanism includes: a storage tank 4; a pump body 6 and a cylinder 7 fixedly installed on the coating tank 2; a mounting frame 8 fixedly installed on the movable end of the cylinder 7; a roller brush 9 rotatably installed in the mounting frame 8; a storage pipe 11 fixedly installed in the mounting frame 8, with several nozzles inserted into the storage pipe 11; and a limiting rod 10 for limiting the mounting frame 8, which is installed through the coating tank 2 and whose bottom end is fixedly connected to the mounting frame 8.

[0023] The pump body 6 has a feed pipe installed at its inlet end, which is connected to the storage tank 4, and a discharge pipe installed at its outlet end, which is connected to the storage pipe 11.

[0024] Feed one end of the plastic film through the feeding opening on the left and place it on the conveyor belt 5. Start the conveyor belt 5 to move the plastic film to the right and discharge it through the feeding opening on the right.

[0025] When coating the plastic film, the cylinder 7 is started to drive the mounting frame 8 to move downward, and the mounting frame 8 drives the roller brush 9 to move downward, so that the roller brush 9 comes into contact with the plastic film. At the same time, the pump body 6 is started to draw out the new material in the storage tank 4 through the feed pipe and transport it to the storage pipe 11 through the discharge pipe, and then spray it onto the surface of the roller brush 9 from several nozzles.

[0026] Since the roller brush 9 is in contact with the plastic film, when the plastic film moves with the conveyor belt 5, it can drive the roller brush 9 to rotate. Through the rotation of the roller brush 9, the new material can be evenly coated on the surface of the plastic film, which improves the coating effect of the plastic film and avoids the uneven coating that is easy to occur when applying the new material to the surface of the plastic film by direct spraying.

[0027] The coating mechanism also includes: a heating box 3 fixedly installed on the coating box 2; an electric heater 12 fixedly installed inside the heating box 3; and a storage box 4 inserted into the heating box 3.

[0028] When coating the plastic film, the water in the heating box 3 can be heated by starting the electric heater 12, thereby realizing water bath heating of the storage box 4. This ensures that the new material in the storage box 4 always maintains the required temperature, thus maintaining good fluidity of the new material and preventing it from solidifying and affecting the coating effect.

[0029] The coating mechanism also includes: a stirring assembly for stirring the new material in the storage tank 4; the stirring assembly includes: a reciprocating screw 14 rotatably mounted on the storage tank 4; a motor 13 that drives the reciprocating screw 14 to rotate; a movable plate 16 threadedly connected to the reciprocating screw 14; and a limiting strip 17 that limits the movable plate 16, the limiting strip 17 being installed through the movable plate 16 and fixedly installed inside the storage tank 4.

[0030] When coating the plastic film, the starting motor 13 drives the reciprocating screw 14 to rotate. Under the limiting action of the limiting strip 17, the movable plate 16 moves up and down along the axial direction of the reciprocating screw 14, thereby realizing the stirring of the new material. This causes the new material to generate convection in the vertical direction, which can break the layering phenomenon caused by the density difference, temperature difference or composition difference of the new material, promote the mixing of the new material in the vertical direction, and improve the uniformity of the new material.

[0031] The mixing assembly also includes: a mixing plate 20 rotatably mounted on the movable plate 16; a connecting gear 18 coaxially connected to the mixing plate 20; a mounting groove formed on the limiting strip 17; and a rack 19 fixedly mounted in the mounting groove; the connecting gear 18 and the rack 19 are meshed with each other.

[0032] As the movable plate 16 reciprocates along the axial direction of the reciprocating screw 14, it drives the stirring plate 20 and the connecting gear 18 to move. Since the connecting gear 18 and the rack 19 are meshed with each other, the connecting gear 18 rotates as it moves with the movable plate 16, thereby driving the stirring plate 20 to rotate. The rotation of the stirring plate 20 further stirs the new material, expands the stirring range, and further improves the uniformity of the new material.

[0033] A stirring blade 15 is fixedly installed on the reciprocating screw 14.

[0034] When the reciprocating screw 14 rotates, it can drive the stirring blade 15 to rotate, thereby stirring the water and making the water temperature uniform, thus improving the uniformity of heating of the storage tank 4.

[0035] Working principle: In use, one end of the plastic film is fed through the feeding opening on the left and placed on the conveyor belt 5. The conveyor belt 5 is started to move the plastic film to the right and discharge it through the feeding opening on the right. When coating the plastic film, the cylinder 7 is started to move the mounting frame 8 downward. The mounting frame 8 moves the roller brush 9 downward, so that the roller brush 9 comes into contact with the plastic film. At the same time, the pump body 6 is started to draw out the new material in the storage tank 4 through the feeding pipe and transport it to the storage pipe 11 through the discharge pipe. Then, it is sprayed onto the surface of the roller brush 9 from several nozzles. Since the roller brush 9 comes into contact with the plastic film, when the plastic film moves with the conveyor belt 5, it can drive the roller brush 9 to rotate. Through the rotation of the roller brush 9, the new material can be evenly coated on the surface of the plastic film, which improves the coating effect of the plastic film and avoids the uneven coating that is easy to occur when coating the surface of the plastic film with new materials by direct spraying.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art.
