Description

Technical Field

[0001] This invention relates to the field of paper cup manufacturing technology, and more particularly to a rapid adhesive bonding device for the bottom of paper cups. Background Technology

[0002] The cup bottom is the core sealing structure of a paper cup, used to seal the bottom of the cup, provide support, and prevent leakage. It directly determines the forming quality and performance of the paper cup. In automated paper cup production lines, cup bottom bonding is a key step in the forming process. Quick and stable bonding of the cup bottom not only improves overall production efficiency and adapts to high-speed assembly line operations, but also ensures a firm bond and tight seal between the cup bottom and the cup body, reducing leakage and detachment issues. To guarantee bonding accuracy and production continuity, the paper cup must remain stable and centered during conveying and bonding. Therefore, the coordination between conveying positioning and rapid bonding is a crucial prerequisite for improving paper cup production efficiency and finished product qualification rate.

[0003] Existing cup bottom pasting devices mostly use a fixed positioning structure, which makes it easy for paper cups to shift during the conveying and pasting process, making it difficult to guarantee centering and positioning accuracy, thereby reducing the yield of finished paper cups.

[0016] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Reference Figure 1 , Figure 2 and Figure 4 An embodiment of the present invention provides a quick-attachment device for the bottom of paper cups, comprising a positioning plate 1, an electric push rod 2 fixedly connected to the outer wall of the positioning plate 1, a drive slider 3 fixedly provided at the output end of the electric push rod 2, a limit rod 4 slidably connected to the inner wall of the drive slider 3, a rotating plate 5 rotatably connected to the outer wall of the drive slider 3, a central disk 6 rotatably connected to the outer wall of the rotating plate 5, a drive plate 7 rotatably connected to the outer wall of the central disk 6, a driven slider 8 rotatably connected to the outer wall of the drive plate 7, a limit bracket 9 fixedly connected to the upper surface of the driven slider 8, and a limit component fixedly connected to the upper surface of the limit bracket 9. Specifically, the electric push rod 2, fixed to the outer wall of the positioning plate 1, is activated, causing the drive slider 3 to slide along the outer wall of the limiting rod 4. The limiting rod 4 limits the sliding of the drive slider 3, reducing its skewness during movement. The movement of the drive slider 3 can drive the rotating plate 5 to rotate, causing the central disk 6 to rotate synchronously. The central disk 6 then drives the drive plate 7 to rotate, thereby pushing the driven slider 8 to slide along the outer wall of the limiting rod 4. The limiting rod 4 simultaneously limits the driven slider 8, enabling the drive slider 3 and the driven slider 8 to move in a centered manner, ultimately ensuring that the product to be die-cut on the upper surface of the transmission roller 12 does not shift during the conveying process.

[0018] Reference Figure 4 The limiting component includes a fixed bracket 10, the lower surface of which is fixedly connected to the upper surface of the limiting bracket 9, and a flexible limiting post 11 is rotatably connected to the inner wall of the fixed bracket 10. Specifically, as the driven slider 8 moves and drives the limiting bracket 9 to move synchronously, the limiting bracket 9 slides on the upper surface of the transmission roller 12 to limit the paper cup body 17. At the same time, the flexible limiting post 11 rotates on the outer wall of the paper cup body 17 to ensure that the flexible limiting post 11 stably guides and limits the paper cup body 17 when it moves, thus ensuring that the bottom sealing of the paper cup body 17 is carried out stably.

[0019] Reference Figure 4 The lower surface of the central disk 6 is rotatably connected to the upper surface of the positioning plate 1, and the outer wall of the driven slider 8 is slidably connected to the inner wall of the positioning plate 1. Specifically, when the central disk 6 rotates on the lower surface of the positioning plate 1, the positioning plate 1 supports the central disk 6, while the driven slider 8 slides on the inner wall of the positioning plate 1, so that the positioning plate 1 limits the driven slider 8, ensuring that the rotation of the central disk 6 and the sliding of the driven slider 8 do not deviate.

[0020] Reference Figure 2 , Figure 3 and Figure 4 The inner wall of the drive slider 3 is slidably connected to the outer wall of the limiting rod 4, and the inner wall of the driven slider 8 is slidably connected to the outer wall of the limiting rod 4; a motor 13 is fixedly connected to the outer wall of the positioning plate 1, and a transmission roller 12 is fixedly installed at the output end of the motor 13; the outer wall of the transmission roller 12 is fixedly connected to the inner wall of the positioning plate 1, and the outer wall of the limiting bracket 9 is slidably installed on the outer wall of the transmission roller 12; a positioning bracket 14 is fixedly connected to the outer wall of the positioning plate 1, and an electric push rod 15 is fixedly connected to the upper surface of the positioning bracket 14, and a sealer 16 is fixedly installed at the output end of the electric push rod 15; a paper cup body 17 is installed on the upper surface of the transmission roller 12, and the outer wall of the paper cup body 17 is installed on the outer wall of the flexible limiting post 11; Specifically, after the user activates the electric push rod 2, the limiting rod 4 slides on the outer wall of the drive slider 3, and the drive slider 3 limits the limiting rod 4. At the same time, after the motor 13 on the outer wall of the positioning plate 1 is activated, the motor 13 drives the transmission roller 12 to rotate, which drives the paper cup body 17 on the upper surface of the transmission roller 12 to ensure that the paper cup body 17 is stably transmitted to the lower surface of the sealer 16. Then, the electric push rod 2 15 is activated to drive the sealer 16 to seal the bottom of the paper cup body 17. At the same time, the fixed bracket 10 moves to drive the flexible limiting post 11 to limit the movement of the paper cup body 17. When the paper cup body 17 moves, the flexible limiting post 11 limits the paper cup body 17. At the same time, the flexible limiting post 11 rotates on the inner wall of the fixed bracket 10. Then, the electric push rod 2 15 on the upper surface of the positioning bracket 14 is activated to drive the sealer 16 to seal the paper cup body 17, so that the sealer 16 has an adhesive sealing effect on the paper cup body 17.

[0021] Working principle: After the user places the paper cup body 17 on the upper surface of the conveyor roller 12, the motor 13 is turned on to drive the conveyor roller 12 to move, so that the paper cup body 17 moves to the lower surface of the sealer 16. When it is necessary to position the paper cup body 17 to prevent deviation, the electric push rod 2 is turned on to drive the drive slider 3 to slide on the outer wall of the limit rod 4. Then the drive slider 3 moves to drive the rotating plate 5 to rotate, so that the rotating plate 5 rotates and drives the center plate 6 to rotate synchronously, so that the center plate 6 rotates and drives the drive plate 7 to rotate synchronously. Then the drive plate 7 rotates and drives the... The driven slider 8 and the limiting bracket 9 slide synchronously on the outer wall of the fixed bracket 10. The movement of the limiting bracket 9 drives the fixed bracket 10 and the flexible limiting post 11 to slide synchronously, so that the flexible limiting post 11 limits the paper cup body 17. When the paper cup body 17 is transported to the lower surface of the sealer 16, the electric push rod 15 on the upper surface of the positioning bracket 14 is activated to drive the sealer 16 to seal the bottom of the paper cup body 17. This achieves the effect of centering without deviation throughout the paper cup transportation process, accurate cup bottom bonding and positioning, and stable and reliable bottom sealing.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
