Description

Technical Field

[0001] This application relates to the technical field of label spraying, and in particular to a spraying apparatus for label production. Background Technology

[0002] A label is a sheet-like item used for identification, classification, description, or decoration. It is widely used in various fields of production and daily life. In industrial production, it is often used to mark product information; in the commercial field, it can indicate the price of goods, etc.; in daily life, it can be used to identify the ownership of items, etc. In the label manufacturing industry, the spraying process is the key step in giving the label its appearance color and pattern.

[0003] Regarding the aforementioned technologies, the inventors believe that traditional label spraying devices have many problems in practical applications. Firstly, the spraying efficiency is low; existing spraying equipment struggles to achieve continuous and efficient operation, and blockages and unstable flow rates easily occur during paint delivery, leading to frequent interruptions in spraying operations and affecting production progress. Secondly, there is a lack of environmental protection measures; excess paint generated during the spraying process cannot be effectively treated, resulting not only in paint waste but also posing a threat to the production environment and the health of operators. Therefore, to solve the above problems, this application provides a spraying device for label production. Utility Model Content

[0019] The following is in conjunction with the appendix Figure 1 - Figure 5 This application will be described in further detail.

[0020] Example 1:

[0021] A spraying device for label production, reference Figure 1 - Figure 5The system includes a conveyor belt 1, a gantry frame 2, and two vertical plates 3. The conveyor belt 1 is rotatably connected to the two vertical plates 3 via multiple rotating shafts. The top of the gantry frame 2 is fixedly connected to a paint tank 4 and a water pump 5. The water pump 5 has a water inlet connected to a water inlet pipe 6. The end of the water inlet pipe 6 away from the water pump 5 extends into the interior of the paint tank 4. The water pump 5 has a water outlet connected to a water outlet pipe 7. The water outlet pipe 7 extends away from the water pump 5 to the top of the gantry frame 2 and is connected to a horizontal pipe 8. The bottom of the horizontal pipe 8 is connected to multiple nozzles 9 at equal intervals. The top inner wall of the gantry frame 2 is equipped with an air duct 10. The air duct 10 has a fan 11 installed inside it. Three heating wires 12 are installed inside the air duct 10 and below the fan 11. Specifically, multiple rotating shafts inside the conveyor belt 1 are rotatably connected to two vertical plates 3, forming the basic structure for label transportation. When the rotating shafts start to rotate under power, they drive the conveyor belt 1 to circulate, thereby realizing the continuous transmission of labels on the device. During transportation, the labels are placed on the surface of the conveyor belt 1 and pass through subsequent processes such as spraying and drying as the conveyor belt 1 moves, providing a stable transmission carrier for the entire spraying operation and ensuring that the labels can pass through each working area in an orderly and efficient manner. After the water pump 5 starts, the paint in the paint tank 4 is extracted through the water extraction pipe 6 connected to the water extraction port. The water extraction pipe 6 extends deep into the paint tank 4 to ensure sufficient extraction of paint. After being pressurized by the water pump 5, the paint enters the drain pipe 7 from the drain port. The drain pipe 7 delivers the paint to the horizontal pipe 8 directly above the gantry frame 2. Multiple nozzles 9 evenly spaced at the bottom of the horizontal pipe 8 can evenly spray the paint onto the label surface on the conveyor belt 1 below. Because the nozzles 9 are evenly spaced and the paint is stably conveyed under the pressure of the water pump 5, large-area and uniform spraying of the labels is achieved, ensuring the consistency of the label surface coating and the quality of the spraying. The air hood 10 installed on the inner wall of the top of the gantry frame 2, with its internal fan 11 and three heating wires 12, together constitute the drying system. After the label is sprayed, it moves to the area below the air hood 10 along the conveyor belt 1. The heating wires 12 are energized and generate heat, which heats the surrounding air. At the same time, the fan 11 starts, blowing the heated air downwards to form a hot airflow. The hot airflow acts directly on the paint on the label surface, accelerating the evaporation of the solvent in the paint and allowing the paint to dry and cure quickly. The airflow of the fan 11 ensures that the hot air can evenly cover the label surface, and the three heating wires 12 provide stable and sufficient heat, ensuring that the drying process is efficient and uniform, avoiding localized poor drying or coating defects caused by excessively fast drying speed.

[0022] Reference Figure 1 A control panel 13 is installed on the outer wall of the gantry frame 2.

[0023] Specifically, operators can set and adjust the operating parameters of various components through the control panel 13, such as the water flow rate of the water pump 5, the speed of the fan 11, and the temperature of the heating wire 12. The control panel 13 is connected to each component via circuitry, converting the operator's input commands into electrical signals and transmitting them to the corresponding equipment to achieve precise control over the paint conveying speed, drying temperature, and airflow. Simultaneously, the control panel 13 can also display the real-time operating status of the device, such as the working parameters of each component and fault alarm information, allowing operators to promptly grasp the equipment's operating status and effectively monitor and manage the device.

[0024] Reference Figure 2 The two ends of the conveyor belt 1 are equipped with anti-deviation plates 14.

[0025] Specifically, during the operation of conveyor belt 1, due to various factors, the label may shift laterally, deviating from the spraying area of ​​nozzle 9, resulting in uneven spraying or even missed spraying. Anti-deviation plates 14 are installed on both sides of conveyor belt 1, forming a physical limiting structure. When the label moves to the sides during transport, it will contact the anti-deviation plates 14 and be blocked by them, thus confining it to the middle area of ​​conveyor belt 1. This ensures that the label is always within the effective spraying range of nozzle 9, ensuring the accuracy and stability of the spraying work and improving the label spraying pass rate.

[0026] The implementation principle of a label production spraying device according to an embodiment of this application is as follows: The water pump 5 is preferably of the LY-JLM type, and the heating wire 12 is preferably of the DRX001 type. Both the water pump 5 and the heating wire 12 are electrically connected to an external power source via a switch. When the label production spraying device is working, multiple rotating shafts inside the conveyor belt 1 rotate under power drive, causing the conveyor belt 1 to circulate and orderly transport the labels placed on its surface to each process area. Simultaneously, the water pump 5 is started by the switch, and paint is drawn from the paint tank 4 through the water suction pipe 6. The water suction pipe 6 extends deep into the paint tank 4 to ensure sufficient paint extraction. The paint, pressurized by the water pump 5, is transported to the horizontal pipe 8 through the drain pipe 7, and then evenly sprayed onto the label surface on the conveyor belt 1 by the equally spaced nozzles 9 at the bottom of the horizontal pipe 8, achieving large-area, uniform spraying. The sprayed labels move with the conveyor belt 1 to the... Below the air hood 10, the heating wire 12 inside the air hood 10 is powered on by a switch to heat the surrounding air. The fan 11 operates synchronously, blowing the hot air downwards to form a hot airflow, which accelerates the evaporation of solvents in the coating on the label surface, promotes rapid drying and curing of the coating, and ensures coating quality. Throughout the process, the operator can set and adjust parameters such as the water pump flow rate, fan speed 11, and heating wire 12 temperature through the control panel 13 on the outer wall of the gantry frame 2. The control panel 13 converts the instructions into electrical signals to control each component and displays the operating status in real time for easy monitoring and management. In addition, the anti-deviation plates 14 at both ends of the conveyor belt 1 form a physical limit. When the label moves laterally, the blocking effect of the anti-deviation plates 14 keeps it within the effective spraying range of the nozzle 9, ensuring the accuracy and stability of the spraying, and ultimately completing the label spraying production efficiently and with high quality.
