Description

Technical Field

[0001] This utility model relates to the field of water cups, and in particular to a water cup with an electrostatic flocked outer coating. Background Technology

[0002] Electrostatic flocking is a process that uses electrostatic effects to flock the surface of objects. After being treated with an electro-adhesive, the flock fibers become polarized under the influence of an electric field. These charged fibers then move in the electric field, and due to the force of the electric field, the originally disordered fibers move upright and are vertically implanted into the surface of the object sprayed with adhesive, creating a pleasing appearance. As the flocked material continuously moves forward, the electrostatic flocking process is completed, and finally, after processing, a unique flocked product is created.

[0003] The industry applications of electrostatic flocking technology are very broad. Flocked products are luxurious, elegant, with a soft luster, a supple feel, and a strong three-dimensional effect. At the same time, due to its simple process, high production efficiency, low cost, and wide applicability, it is widely used in various industries. Water cups, as daily necessities, are in high demand.

[0029] Detailed implementation plan: See below Figures 1-4 This utility model relates to a water cup with an electrostatic flocked outer coating, comprising a cup body and a cup lid. The upper end of the cup body has a cup mouth, and the cup lid covers the upper part of the cup body and covers the cup mouth. It also includes:

[0030] The flocked outer layer covers at least the outer wall of the cup body. The flocked outer layer includes an adhesive layer and a flocked layer from the inside to the outside. There is a blank area without flocking between the upper end of the flocked outer layer and the cup mouth.

[0031] As a preferred embodiment of this example, please refer to Figure 1 As can be seen, the flocked outer layer located on the outer surface of the cup body is the first layer, and the outer surface of the cup lid is covered with a second layer. The second layer and the first layer have the same structure and both include an adhesive layer and a flocked layer.

[0032] Then, in this embodiment, the cup lid has an assembled state mounted on the cup body, in which the second layer and the lower end extend to the upper end of the first layer.

[0033] Furthermore, in this embodiment, the flocked outer layer also covers the bottom of the cup body, and the flocked outer layer located on the outer wall and bottom of the cup body is seamlessly connected.

[0034] Here, by flocking both the cup body and the lid, when the lid is placed over the cup body, all areas of the outer surface of the cup are flocked, resulting in a more aesthetically pleasing appearance.

[0035] Next, in this embodiment, the flocking fibers are evenly distributed at all locations on the flocked layer.

[0036] Furthermore, in practical applications, the flocking layer can have any of the following flocking thicknesses: 1.5*0.5mm, 3*0.6mm, 15*3mm, and 15*4mm, thus providing different flocking feel.

[0037] In this embodiment, the water cup is a handleless water cup. The handleless design allows for easier electrostatic spraying and flocking processes, enabling the adhesive and flocking to adhere more completely to the outer surface of the cup, resulting in a more aesthetically pleasing appearance.

[0038] More specifically, in this embodiment, all the flocked fibers on the flocked layer are the same color. In practical applications, different colors can be used at different locations on the flocked layer to create unique and aesthetically pleasing patterns.

[0039] For easier understanding and to provide a reference on how to better perform flocking on water cups, please refer to [link / reference]. Figure 4 The following describes the processing and production steps for forming the flocked outer layer in this application:

[0040] S1. Provide a water cup after removing the packaging bag, with a drinking spout at the top opening; or provide an existing finished water cup with a drinking spout at the top, with a certain distance between the spout and the outer surface of the cup to prevent accidental ingestion of lint during drinking, and the spout and inner liner of the water cup are made of stainless steel.

[0041] S2. Electrostatic dust removal: Electrostatic dust removal equipment is used to remove dust from the inside and outside of the cup. A high-voltage electric field is used to ionize the flue gas, and the dust in the airflow becomes charged and separates from the airflow under the action of the electric field, so that the water cup is in a dust-free state. By placing the water cup in the electrostatic dust removal equipment, the surface of the cup can be cleaner, which makes it easier to apply adhesive and flocking later and make the surface of the water cup more beautiful.

[0042] S3. Applying Adhesive: Using an adhesive applicator, adhesive is applied to the rim of the water cup to ensure a smooth and aesthetically pleasing finish and to prevent contamination of the inner liner. During the adhesive application process, the cup is placed on a rotating platform, allowing it to rotate. The adhesive applicator seals the rim of the cup, preventing contamination of the inner liner, and also seals the drinking area on the outside of the rim with adhesive, preventing contamination of the outer rim.

[0043] S4. Electrostatic spraying: Using electrostatic spraying equipment, adhesive is evenly sprayed onto the surface of the water cup that needs to be flocked. During the spraying process, the adhesive sprayed from the spray gun is atomized and carries a negative charge. When the water cup is placed at zero potential or grounded, the atomized adhesive is attracted by the cup body with a different potential and deposited on the surface of the water cup, thus completing the electrostatic spraying process.

[0044] S5. Electrostatic flocking: Electrostatic flocking device is used to flock the outside of the cup. After the electrostatic flocking device is connected to the power supply, a high voltage electrostatic field is generated in the flocking chamber. Under the action of the high voltage electrostatic field, the flocking fibers fly to the surface of the cup and are vertically planted on the surface of the cup coated with plastic powder. The cup rotates during the flocking process.

[0045] S6. Oven drying: Place the water cup into the hot air circulating oven. The oven's air circulation system uses a fan to circulate air, ensuring uniform and efficient air circulation. The air source is driven by a circulating fan motor, which drives the impeller through the heater to deliver hot air. The hot air then travels through the air duct to the oven chamber. The used air is then drawn into the air duct to become the air source again for recirculation and heating, ensuring uniform temperature inside the oven. When the temperature fluctuates due to opening and closing the door, the air circulation system quickly returns to normal operation until the set temperature is reached, thereby accelerating the drying of the adhesive.

[0046] S7. Remove the tape: Remove the tape covering the mouth of the water cup to make the mouth of the bottle cleaner and more aesthetically pleasing.

[0047] In S1, the water cup is a handleless water cup. The handleless water cup makes it easier to apply glue and flock during the electrostatic spraying and electrostatic flocking process, allowing the glue and flock to adhere more completely to the outer surface of the water cup, achieving a more aesthetically pleasing effect.

[0048] In S2, the voltage range of the high-voltage electric field of the electrostatic precipitator is 1-160V.

[0049] In S3, the adhesive application equipment is called an adhesive application machine. The adhesive application machine mainly uses a PLC as the control center of the entire system to realize the entire application process. The PLC outputs pulses from a specific pulse output port to control the pneumatic components and the PUR dry particle machine, so that the LCD alternating rotating platform moves accurately in a circumferential direction at a predetermined position.

[0050] In S4, the electrostatic spraying equipment is an electrostatic gun, and the water cup is placed inside the electrostatic spraying equipment and rotates in a circular motion during the electrostatic spraying process.

[0051] In S4, the amount of adhesive applied is 6-20g per cup, and the application time for each cup is 25 seconds.

[0052] In S5, the voltage range of the electrostatic field is 1-160V.

[0053] In S5, the thickness of the fibers is 1.5*0.5mm, 3*0.6mm, 15*3mm, and 15*4mm.

[0054] In S6, the drying temperature is 90-160°C and the drying time is 20 minutes.

[0055] The following explains the precautions and specific process flow for the above processing and production steps: During the process of removing the packaging bag from the water cup, the existing finished water cup will be provided. The top of the water cup has a drinking spout, and there is a certain distance between the spout and the outer surface of the cup. A comprehensive inspection of the inside and outside of the water cup will be conducted to ensure there are no defects. During the electrostatic dust removal process, the water cup is placed in an electrostatic dust removal device. A high-voltage electric field is used to ionize the flue gas, causing the dust particles in the airflow to become charged and separate from the airflow under the influence of the electric field, thus ensuring the water cup is dust-free. During the adhesive application process, adhesive application equipment is used to ensure a seal between the water cup spout and the drinking area on both sides of the spout. During the electrostatic adhesive spraying process, the adhesive sprayed from the spray gun is atomized and carries a negative charge. The water cup is placed at zero potential or grounded, and the atomized adhesive is attracted by the cup body with an opposite potential. The process involves several steps: First, the adhesive is deposited onto the surface of the water cup via electrostatic spraying. During this process, the cup is placed on a rotating platform, allowing for circular motion. The electrostatic gun sprays the adhesive from multiple angles and directions, ensuring even and thorough adhesion. Second, during electrostatic flocking, the cup is also placed on the rotating platform, allowing for multi-directional and multi-angle flocking with a high flocking rate. Third, during oven drying, the cup is placed inside a fan-driven air circulation system, ensuring efficient and uniform airflow to accelerate adhesive drying. After drying, the flocked areas are thoroughly inspected to ensure no areas remain un-flocked. Finally, all tape is removed from the cup rim to maintain a clean and aesthetically pleasing appearance. The electrostatic flocking method used to produce this water cup significantly improves both its aesthetics and comfort.

[0056] The above description of a water cup with an electrostatic flocked outer layer is only a preferred embodiment of this utility model and does not limit the patent scope of this utility model. All equivalent structural transformations made under the inventive concept of this utility model using the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
