Description

Technical Field

[0001] This utility model relates to the field of adhesive coating technology in paper cup production, and in particular to an adhesive coating machine for producing thermochromic paper cups. Background Technology

[0002] In the modern paper cup manufacturing industry, with the continuous changes in market demand and the increasing personalization requirements of consumers, a type of thermochromic paper cup has emerged. This paper cup displays unique color changes when heated, bringing a novel experience to consumers and thus attracting widespread attention. In the production process of thermochromic paper cups, the glue coating stage plays a crucial role. The quality of the glue coating not only affects the sealing and durability of the paper cup but also influences the adhesion and effect of the thermochromic coating. To meet the needs of efficient, precise, and stable glue coating, developing a glue coating machine specifically designed for the production of thermochromic paper cups has become an urgent problem to be solved in the industry.

[0003] Current paper cup gluing machines typically employ a traditional gluing roller design. A motor drives the roller to rotate, evenly applying glue to the edge of the paper cup. Technically, this relies on the adhesive properties of the glue, causing it to adhere to the roller surface and then transfer it to the paper cup upon contact. This structure and principle have been effective for gluing ordinary paper cups and were widely used in the paper cup manufacturing industry for a considerable period. However, with the emergence of new products like thermochromic paper cups, existing gluing machines have gradually revealed limitations in meeting their specific production requirements.

[0004] However, existing technologies have a significant problem: after the glued paper cups are folded using a cup-folding machine, there is a lack of effective drying measures. Typically, glued paper cups need to air dry naturally, which leads to insufficient adhesion at the edges of the cups during subsequent processing due to the glue not being fully dried. This not only reduces the quality of the paper cups but may also increase the defect rate and production costs. Furthermore, natural drying requires a considerable amount of time for the glue to dry, severely impacting production efficiency and failing to meet the demands of modern large-scale, high-efficiency paper cup production. This hinders the expansion of the production scale and market promotion of thermochromic paper cups. Therefore, this paper proposes a glue-coating machine for thermochromic paper cup production to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a glue coating machine for the production of thermochromic paper cups, which aims to improve the problem of slow drying time of paper cup glue in the prior art.

As a further description of the above technical solution: The transport component includes a motor, which is fixedly connected to the outer wall of the fixed frame, and a conveyor belt is fixedly connected to the output end of the motor. The outer wall of the conveyor belt is fixedly connected to the inner wall of the fixed frame. As a further description of the above technical solution: The mixing assembly includes a glue applicator cover, which is located on the top of the glue applicator body. A ring array of fixing rods is fixedly connected to the inner wall of the glue applicator cover, and a fixing gear is fixedly connected to the other end of each fixing rod. As a further description of the above technical solution: A second motor is fixedly connected to the inner wall of the glue applicator cover, and a rotating shaft is fixedly connected to the output end of the second motor. The rotating shaft is rotatably connected to the inner wall of the fixed gear.

[0007] This utility model has the following beneficial effects: In this invention, when the glue on the folded paper cups is air-dried by the cup-folding machine, the electric pusher is turned on to push the cups to the appropriate position. The position can be adjusted according to different sizes of paper cups. The electric pusher drives the slide rail to adjust the positioning frame to fit different sizes of paper cups. After the paper cups are air-dried, the quality problems caused by insufficient adhesion of the paper cup edges due to the glue not being dry during subsequent processing can be avoided. At the same time, it also solves the problem of affecting production efficiency by waiting for the glue to dry.

[0008] In this invention, when applying glue to paper cups, the glue in the glue applicator body may clump or separate over time. The stirring rod in the glue applicator body stirs the glue during the application process, effectively preventing the glue from clumping or separating, thus improving the glue applicator efficiency, avoiding blockages caused by clumping and increasing downtime, and also preventing glue separation from affecting the glue's viscosity, thereby effectively improving production efficiency.

The connecting rods 11 are made of stainless steel and connected to the L-shaped plate 10 at both ends via bearings, allowing for flexible rotation. Each connecting rod 11 is equipped with a transmission assembly that transmits the rotation of the connecting rod 11 to the positioning frame 16.

When the motor 18 drives the rotating shaft 19 to rotate, it drives the gear connecting rod 24 to rotate through gear meshing.A gear connecting rod 26, also made of stainless steel, is fixedly connected to the bottom of the support frame 23. A gear 25, also made of stainless steel, is rotatably connected to the bottom of the gear connecting rod 26 via a bearing. Gear 25 meshes with gear 22 at the bottom.

A fixing rod 28, made of solid stainless steel, is fixedly connected to the bottom of connecting rod 27. A stirring rod 29, also made of stainless steel, is welded to its outer wall and effectively stirs the adhesive, preventing it from clumping or separating. Working principle: When drying the formed paper cups, firstly, the electric push rod 9 is turned on, and then the output end of the electric push rod 9 pushes the outer wall of the push block 10. Then, the push block 10 pushes the fixed block 11 to move. Then, the fixed block 11 drives the connecting rod 11 to move. Then, the other end of the connecting rod 11 drives the connecting frame 12 to move. Then, the top of the connecting frame 12 slides on the bottom of the slide rail 3. Then, the connecting frame 12 drives the connecting frame 2 14 to move. Then, the connecting frame 2 14 drives the fixed rod 15 to move. Then, the fixed rod 15 drives the positioning frame 16 to move. By adjusting the positioning frame 16, it can adapt to paper cups of different sizes. When the paper cup passes through the positioning frame 16 on the conveyor belt 7, the air dryer 6 above quickly dries the glue on the paper cup. The positioning frame 16 can prevent the paper cup from shifting due to excessive wind force, thus affecting subsequent processing.

[0012] During the glue coating process on paper cups, the switch of motor 18 inside the glue coating machine cover is turned on. The output end of motor 18 drives the rotating shaft 19 to rotate. The rotation of the rotating shaft 19 then drives the support frame 23 to rotate. The support frame 23 then drives the gear connecting rod 24 to rotate. The top gear 22 of the gear connecting rod 24 then rotates on the outer wall of the fixed gear 20. The bottom gear 22 of the gear connecting rod 24 then drives the gear 25 to rotate. The gear 25 then drives the connecting rod 27 to rotate. The connecting rod 27 then drives the fixed rod 28 to rotate. The fixed rod 28 then drives the stirring rod 29 located on the outer wall to rotate. The stirring rod 29 then stirs the glue inside the glue coating machine body 1 to prevent the glue from clumping together and affecting production efficiency.
