Description

Technical Field

[0001] This utility model relates to the technical field of cup paper processing equipment, specifically a cup paper uniform coating device. Background Technology

[0002] Uniform coating of cup paper is a key process to improve the quality and performance of cups, enhancing the paper's waterproof and oil-proof properties and ensuring safe use. Cup paper coating usually adopts an extrusion coating process, in which thermoplastic plastic particles such as polyethylene and polypropylene are heated and melted, and then extruded from the die into a thin film by the screw of an extruder. At the moment of extrusion, the film is uniformly covered on the surface of the cup paper under certain pressure and temperature. After cooling and solidification, it adheres tightly to the paper to form a plastic film with waterproof and oil-proof functions.

[0003] Currently, the coating equipment for cup paper leaves some residue after extrusion film formation, resulting in material waste. During coating, the film is directly sprayed through an extruder, which leads to uneven film formation and affects the overall uniformity of the cup paper film. Utility Model Content

[0004] The purpose of this invention is to provide a device for uniformly coating cup paper to solve the technical problem of uneven coating.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a uniform coating device for cup paper, comprising a base plate, a fixed frame with a nozzle fixedly connected to the upper end of the base plate, the nozzle and an external extruder, a first sliding groove opened on the base plate, and a second sliding groove opened on both sides of the fixed frame, a stepper motor fixedly connected to one side of the fixed frame, a bidirectional lead screw fixedly connected to the output end of the stepper motor and rotatably connected to the middle side wall of the fixed frame through a bearing, threaded sleeves connected to both sides of the bidirectional lead screw, a sliding rod fixedly connected to the lower end of the threaded sleeve, the lower end of the sliding rod slidably connected to the first sliding groove, a support rod rotatably connected to the upper end of the threaded sleeve through a rotating shaft, a support plate rotatably connected to the upper end of the support rod through a rotating shaft, a sliding plate fixedly connected to both sides of the support plate, and the side of the sliding plate away from the support plate slidably connected to the second sliding groove.

[0006] As a further embodiment of this utility model, the upper end of the support plate is connected to the storage cylinder by bolt thread, the bottom end of the storage cylinder is connected to the screw rod by thread, the upper end of the screw rod is rotatably connected to the spray plate by bearing, and one side of the upper end of the spray plate is fixedly connected to the electric telescopic rod by bracket, and the output end of the electric telescopic rod is fixedly connected to the silicone scraper.

[0007] As a further embodiment of this utility model, the screw wall near the upper end is fixedly connected to the turntable.

[0008] As a preferred embodiment of this utility model, self-locking casters are fixedly connected to the two corners of the lower end of the base plate in a symmetrical arrangement.

[0009] Compared with the prior art, the beneficial effects of the present invention for a uniform coating device for cup paper are as follows: by setting the nozzle of an external extruder, the raw material can be sprayed out quickly. At the same time, the different heights of the cup paper can be adjusted according to the bidirectional screw to spray and form a film, increasing the overall flexibility of the coating process. In addition, the electric telescopic rod and silicone scraper are rotated during the coating process to increase the uniformity of the coating. The excess raw material is collected during the coating process through a detachable storage cylinder, which facilitates subsequent disassembly and cleaning. Attached Figure Description

[0020] See Figure 1-5 As shown in the figure, an embodiment of the present invention provides a uniform coating device for cup paper, comprising a base plate 1, a fixed frame 2 with a nozzle fixedly connected to the upper end of the base plate 1, the nozzle and an external extruder, a first groove 4 on the base plate 1, and second grooves 5 on both sides of the fixed frame 2, a stepper motor 6 fixedly connected to one side of the fixed frame 2, a bidirectional lead screw 3 fixedly connected to the output end of the stepper motor 6 and rotatably connected to the middle side wall of the fixed frame 2 via bearings, threaded sleeves 7 on both sides of the bidirectional lead screw 3, a slide rod 8 fixedly connected to the lower end of the screw sleeve 7, the lower end of the slide rod 8 slidably connected to the first groove 4, a support rod 9 rotatably connected to the upper end of the screw sleeve 7 via a rotating shaft, a support plate 10 rotatably connected to the upper end of the support rod 9 via a rotating shaft, a slide plate 11 fixedly connected to both sides of the support plate 10, the side of the slide plate 11 away from the support plate 10 slidably connected to the second groove 5, and symmetrically arranged self-locking universal wheels fixedly connected to the lower corners of the base plate 1.

[0021] In use, after moving the equipment to a suitable position using the self-locking casters at the lower end of the base plate 1, the casters are locked. At this time, the nozzle at the upper end of the fixing frame 2 is connected to the output end of the extruder. Then, the stepper motor 6 is started by connecting an external power source. The output end of the stepper motor 6 drives the bidirectional lead screw 3. The output end of the bidirectional lead screw 3 drives the bidirectional lead screw 3 to rotate. The rotation of the bidirectional lead screw 3 drives the screw sleeve 7. The screw sleeve 7 then moves continuously towards the middle of the wall of the bidirectional lead screw 3 through the sliding limit action of the first slide groove 4 and the slide rod 8. At this time, the support rod 9 connected by rotation will continuously raise the support plate 10. When the support plate 10 rises, it will continuously rise under the sliding limit action of the slide plate 11 and the second slide groove 5, thereby driving the cup paper to rise and fall to different heights for easy spraying.

[0022] The upper end of the support plate 10 is connected to the storage cylinder 12 by bolt thread, the bottom end of the storage cylinder 12 is connected to the screw rod 13 by thread, the upper end of the screw rod 13 is rotatably connected to the spray plate 15 by bearing, the upper side of the spray plate 15 is fixedly connected to the electric telescopic rod 16 by bracket, the output end of the electric telescopic rod 16 is fixedly connected to the silicone scraper 17, and the rod wall of the screw rod 13 near the upper end is fixedly connected to the turntable 14.

[0023] In use, the cup paper is laid on the spray plate 15. When the extruder-connected pipe sprays out the film-forming material, the excess sprayed material will flow into the storage cylinder 12. At this time, the electric telescopic rod 16 is activated. The electric telescopic rod 16 will drive the silicone scraper 17 to descend and block the cup paper, and then push the support plate 10. The support plate 10, under the force and the rotation of the upper bearing of the screw 13, increases the overall uniformity of film formation. At the same time, the excess material will be scraped off by the silicone scraper 17 and stored in the storage cylinder 12. After the coating is completed, the storage cylinder 12 is disassembled by bolts, and the turntable 14 is pushed. The turntable 14 is driven by force to rotate the screw 13, thereby driving the screw 13 to be removed from the storage cylinder 12, making it convenient to move the storage cylinder 12 for cleaning.

[0024] The foregoing has shown and described the basic principles of the present invention. The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. The above embodiments and descriptions in the specification are only illustrative of the principles of the present invention. Any modifications, equivalent substitutions, and improvements made within the scope of the present invention without departing from the scope of the present invention should be included within the protection scope of the present invention.
