[0001] This utility model relates to the field of paper cup processing technology, specifically to a coating machine for paper cup processing. Background Technology

[0002] Paper cups are paper containers made by mechanically processing and bonding paper (white cardboard) made from chemical wood pulp. They are cup-shaped in appearance. Paper cups for frozen foods are coated with wax and can hold ice cream, jam, butter, etc. Paper cups for hot drinks are coated with plastic and can withstand temperatures above 90°C, even boiling water. Paper cups are characterized by being safe, hygienic, lightweight and convenient. They can be used in public places, restaurants and eateries, and are disposable items.

[0003] A search revealed a Chinese patent publication dated December 30, 2022, with publication number CN218171559U, describing a paper cup laminating machine. The machine comprises a body and a cardboard to be laminated. The body has an inlet and an outlet that communicate with the interior. The cardboard passes through the inlet and outlet sequentially. A laminating mechanism is installed inside the machine for laminating the cardboard. A scraper is slidably mounted on the side of the body near the outlet. A scraper blade is fixedly mounted on the top of the scraper. The scraper has a T-shaped structure and is made of stainless steel. A collection box is placed on top of the scraper. The top of the collection box has a groove, and a drain end is located on the side of the collection box near the scraper.

[0004] While the aforementioned existing technical solutions are beneficial for saving raw materials, the collection box of the device has a limited capacity and requires frequent replacement and cleaning, which leads to frequent equipment downtime and reduces the equipment's working efficiency. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a paper cup coating machine to solve the problem mentioned in the background technology that requires frequent equipment shutdowns, thus reducing the working efficiency of the equipment.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a paper cup coating machine, comprising a base plate and a working box connected to the top of the base plate. The lower inner wall of the working box has an arc-shaped material groove. A first rotating rod and a second rotating rod are rotatably connected to the inner wall of the working box. A coating roller cooperating with the arc-shaped material groove is connected to the first rotating rod. A pressure roller cooperating with the coating roller is connected to the second rotating rod. One end of the first rotating rod and the second rotating rod penetrates the working box and is respectively connected to a first gear and a second gear. The first gear meshes with the second gear. A motor connected to the first rotating rod is installed on the outer wall of the working box. The outer wall of the working box has a feed inlet and a discharge outlet. The inner side wall of the working box has an upper plate and a lower plate that cooperate with the discharge outlet. The lower plate has a feed outlet and a scraper that cooperates with the feed outlet. The scraper has a first receiving groove inside and a first heating plate inside. The arc-shaped feed trough has a second receiving groove inside and a second heating plate inside. The outer wall of the working box has a battery that is electrically connected to the first heating plate and the second heating plate.

[0009] By adopting the above technical solution, liquid coating is injected into the arc-shaped trough. The motor is started to drive the first rotating rod and the first gear to rotate. The first gear and the second gear cooperate to make the first rotating rod drive the second rotating rod to rotate, thereby causing the coating roller and the pressure roller to rotate simultaneously. The coating roller carries the coating in the arc-shaped trough to cover the coating roller. At this time, the cardboard is inserted from one end of the feed port, so that the cardboard passes between the coating roller and the pressure roller, and then extends out from the discharge port. This allows the coating roller to apply the coating to the bottom end of the cardboard. At this time, the scraper is used to scrape the coating at the bottom end of the cardboard and scrape off the excess coating. This allows the excess coating to flow along the scraper through the feed port and then into the arc-shaped trough, thereby recovering the scraped coating. The first heating plate is used to prevent the coating from condensing on the scraper, and the second heating plate is used to prevent the coating in the arc-shaped trough from condensing, thereby achieving the purpose of saving resources, avoiding frequent equipment downtime, and improving work efficiency.

[0010] Optionally, the lower plate has a sliding opening, and a U-shaped component is slidably connected to the sliding opening. One end of the U-shaped component is connected to a scraper. A fixed plate is connected to the inner wall of the work box. Two threaded rods are threadedly connected to the U-shaped component. The two ends of the threaded rods are respectively connected to the U-shaped component and the fixed plate. Both threaded rods are provided with worm gears. A worm that cooperates with the two worm gears is rotatably connected to the inner wall of the work box. One end of the worm passes through the work box and is connected to a rotating handle.

[0011] By adopting the above technical solution, rotating the rotating handle drives the worm gear to rotate, the worm gear drives the worm wheel and the threaded rod to rotate, the threaded rod drives the U-shaped part to move, and the U-shaped part drives the scraper to move, thereby adjusting the distance between the scraper and the upper plate, and adjusting the gap between the scraper and the cardboard, thereby adjusting the film thickness.

[0012] Optionally, the upper inner sidewall of the U-shaped component is connected to two limiting slide rods, both of which are slidably connected to the lower plate.

[0013] By adopting the above technical solution, the limiting slide bar is used to limit the U-shaped part, thereby preventing the U-shaped part from shaking and the scraper from shaking, thereby achieving the purpose of improving the scraping effect.

[0014] Optionally, two first limiting plates that cooperate with the feed inlet are connected to the inner side wall of the working box, and two inclined limiting plates are connected to the end of the upper plate and the lower plate away from the discharge port.

[0015] By adopting the above technical solution, the first limiting plate is used to limit the paperboard when it is inserted into the working box, so that one end of the paperboard can be smoothly inserted between the pressure roller and the laminating roller. The inclined limiting plate is used to facilitate the paperboard to move between the upper plate and the lower plate, so that one end of the paperboard can pass smoothly through the discharge port, thus facilitating the operation of the paperboard by personnel.

[0016] Optionally, the front end of the work box is provided with a transparent observation window.

[0017] By adopting the above technical solution, the transparent observation window is used to facilitate personnel to observe the situation inside the work box, thereby making it easier to detect and eliminate faults in a timely manner.

[0018] (III) Beneficial Effects

[0019] In summary, this utility model has at least one of the following beneficial technical effects:

[0020] This paper cup processing laminating machine injects liquid coating into an arc-shaped trough. The motor is started, driving the first rotating rod and the first gear to rotate. The first and second gears mesh, causing the first rotating rod to drive the second rotating rod to rotate, thus causing the laminating roller and the pressure roller to rotate simultaneously. The laminating roller carries the coating from the arc-shaped trough onto itself. At this point, paperboard is inserted from one end of the feed inlet, passing between the laminating roller and the pressure roller, and then extending from the discharge outlet. This allows the laminating roller to apply coating to the bottom of the paperboard. A scraper is used to smooth the coating at the bottom of the paperboard, scraping off excess coating. This allows the excess coating to flow along the scraper through the feed inlet and then into the arc-shaped trough for recycling. A first heating plate prevents coating from condensing on the scraper, and a second heating plate prevents coating from condensing in the arc-shaped trough, thus saving resources, avoiding frequent equipment downtime, and improving work efficiency.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings.

[0029] Reference Figures 1-5 A paper cup laminating machine includes a base plate 1 and a working box 2 connected to the top of the base plate 1. The lower inner wall of the working box 2 has an arc-shaped material groove 3. A first rotating rod 4 and a second rotating rod 5 are rotatably connected to the inner wall of the working box 2. A laminating roller 6, which cooperates with the arc-shaped material groove 3, is connected to the first rotating rod 4.

One end of the first rotating rod 4 and the second rotating rod 5 passes through the working box 2 and is respectively connected to a first gear 8 and a second gear 9. The first gear 8 and the second gear 9... The working box 2 is meshed with a motor 10 connected to the first rotating rod 4, which is installed on the outer wall of the working box 2. The outer wall of the working box 2 has an inlet and an outlet. The inner wall of the working box 2 has an upper plate 11 and a lower plate 12 that cooperate with the outlet. The lower plate 12 has a feed port and a scraper 13 that cooperates with the feed port. The scraper 13 has a first receiving groove inside, and a first heating plate 14 is installed inside the first receiving groove. The arc-shaped material trough 3 has a second receiving groove inside, and a second heating plate 15 is installed inside the second receiving groove. A battery 16, electrically connected to the first heating plate 14 and the second heating plate 15, is installed on the outer wall of plate 2. Liquid coating is injected into the arc-shaped trough 3. The motor 10 is started to drive the first rotating rod 4 and the first gear 8 to rotate. The first gear 8 and the second gear 9 cooperate to make the first rotating rod 4 drive the second rotating rod 5 to rotate, thereby causing the laminating roller 6 and the pressure roller 7 to rotate simultaneously. The laminating roller 6 drives the coating in the arc-shaped trough 3 to cover the laminating roller 6. At this time, the paperboard is inserted from one end of the feed port, so that the paperboard passes between the laminating roller 6 and the pressure roller 7, and then exits from the feed port. The feed inlet extends, allowing the coating roller 6 to apply the coating to the bottom of the cardboard. At this time, the scraper 13 is used to smooth the coating on the bottom of the cardboard and scrape off the excess coating. This allows the excess coating to flow along the scraper 13 through the feed inlet and then into the arc-shaped feed trough 3, thereby recovering the scraped coating. The first heating plate 14 is used to prevent the coating from condensing on the scraper 13, and the second heating plate 15 is used to prevent the coating from condensing in the arc-shaped feed trough 3, thereby saving resources, avoiding frequent equipment downtime, and improving work efficiency.

One end of the U-shaped part 17 is connected to the scraper 13. A fixed plate 18 is connected to the inner side wall of the working box 2. Two threaded rods 19 are threadedly connected to the U-shaped part 17. The two ends of the threaded rods 19 are respectively connected to the U-shaped part 17 and the fixed plate 18. Each of the two threaded rods 19 is provided with a worm gear 20. A worm 21 that cooperates with the two worm gears 20 is rotatably connected to the inner side wall of the working box 2. One end of the worm 21 passes through the working box 2 and is connected to a rotating handle 22. Rotating the rotating handle 22 drives the worm 21 to rotate. The worm 21 drives the worm gear 20 and the threaded rod 19 to rotate. The threaded rod 19 drives the U-shaped part 17 to move. The U-shaped part 17 drives the scraper 13 to move, thereby adjusting the distance between the scraper 13 and the upper plate 11, and adjusting the spacing between the scraper 13 and the cardboard, thereby adjusting the thickness of the coating.

Both limiting slide rods 23 are slidably connected to the lower plate 12. The limiting slide rods 23 are used to limit the U-shaped part 17 to prevent the U-shaped part 17 from shaking, thereby preventing the scraper 13 from shaking, and thus achieving the purpose of improving the scraping effect.

[0032] Reference Figure 3 and Figure 4 The inner wall of the working box 2 is connected to two first limiting plates 24 that cooperate with the feed port. The upper plate 11 and the lower plate 12 are each connected to two inclined limiting plates 25 at the end away from the discharge port.

The inclined limiting plates 25 are used to facilitate the paperboard to move between the upper plate 11 and the lower plate 12, so that one end of the paperboard can pass smoothly through the discharge port, thus facilitating the operation of the paperboard by personnel.

[0033] Reference Figure 1 The front end of the work box 2 is provided with a transparent observation window 26. The transparent observation window 26 is used to facilitate personnel to observe the situation inside the work box 2, so as to facilitate timely detection and troubleshooting of faults.

[0034] In summary, the working principle and process of this paper cup laminating machine are as follows: First, liquid coating is injected into the arc-shaped trough 3. Then, the motor 10 is started, driving the first rotating rod 4 and the first gear 8 to rotate. The first gear 8 and the second gear 9 engage, causing the first rotating rod 4 to drive the second rotating rod 5 to rotate. This causes the laminating roller 6 and the pressure roller 7 to rotate simultaneously. The laminating roller 6 carries the coating from the arc-shaped trough 3 to cover its surface. At this point, paperboard is inserted from one end of the feed inlet, allowing it to pass through the laminating roller 6 and the pressure roller 7. Between the rollers 7, the coating roller 6 extends from the discharge port, allowing the coating roller 6 to apply the paint to the bottom end of the cardboard. At this time, the scraper 13 is used to smooth the paint on the bottom end of the cardboard, scraping off excess paint. This allows the excess paint to flow along the scraper 13 through the feed port and then into the arc-shaped feed trough 3, thus recovering the scraped paint. The first heating plate 14 prevents the paint from condensing on the scraper 13, and the second heating plate 15 prevents the paint from condensing in the arc-shaped feed trough 3, thereby achieving the purpose of saving resources. This avoids frequent equipment downtime and improves work efficiency. Rotating the rotating handle 22 drives the worm gear 21 to rotate, which in turn drives the worm wheel 20 and the threaded rod 19 to rotate. The threaded rod 19 drives the U-shaped part 17 to move, which in turn drives the scraper 13 to move, thereby adjusting the distance between the scraper 13 and the upper plate 11, and adjusting the gap between the scraper 13 and the cardboard, thus adjusting the film thickness. The limiting slide bar 23 is used to limit the U-shaped part 17 to prevent it from shaking, thus preventing the scraper 13 from shaking, thereby improving the smoothing effect. The first limiting plate 24 is used to limit the cardboard when it is inserted into the working box 2, so that one end of the cardboard can be smoothly inserted between the pressure roller 7 and the coating roller 6. The inclined limiting plate 25 is used to facilitate the movement of the cardboard between the upper plate 11 and the lower plate 12, so that one end of the cardboard can pass smoothly through the discharge port, thus facilitating personnel to operate the cardboard. The transparent observation window 26 is used to facilitate personnel to observe the situation inside the working box 2, thus facilitating timely detection and troubleshooting of faults.

[0035] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
