Description

Technical Field

[0001] This utility model relates to the field of spraying equipment technology, and in particular to an anti-slip liquid spraying machine. Background Technology

[0002] In modern industrial production, the stability and safety of products during stacking and transportation are crucial. To ensure that products do not slip or fall during stacking, companies choose to coat the outer surface of product packaging with anti-slip liquid. While this measure is effective, it also presents challenges and cost issues related to the coating equipment.

[0003] First, the equipment used for applying anti-slip fluid is typically expensive. This equipment often requires high-precision control and complex mechanical structures to ensure the anti-slip fluid is applied evenly and precisely to the product surface. Due to the high technological content of this equipment, it usually needs to be imported, which not only increases the purchase cost but also involves a series of additional expenses such as transportation and tariffs. Furthermore, the maintenance and repair of this equipment requires specialized technical support, further increasing long-term operating costs.

[0004] Secondly, the amount of anti-slip fluid used is also a significant issue. To ensure stacking stability, sufficient anti-slip fluid needs to be applied to the product surface, which often means substantial consumption. Increased anti-slip fluid costs directly impact the total product cost, reducing the company's profit margin.

[0005] Furthermore, the limited means of controlling the amount of anti-slip fluid applied is also a problem. Traditional spraying equipment often only offers limited adjustment options, making it impossible to flexibly adjust the amount of anti-slip fluid used according to different product characteristics and stacking requirements. This single control method restricts production flexibility and product diversity, making it difficult for companies to quickly adjust their production strategies in the face of market changes.

[0006] Finally, the limited sourcing of equipment components is also a significant problem. Because key components for these devices often rely on specific foreign suppliers, any disruptions to the supply chain, such as supplier shutdowns or transportation interruptions, could lead to production disruptions for the company. This dependence limits the company's autonomy and resilience, hindering its stable development.

[0007] To address these issues, companies need to seek more economical, flexible, and sustainable solutions. Developing new spraying equipment is a crucial element in this process. By developing new equipment, costs can be reduced while improving flexibility and accuracy. This equipment can adopt a modular design, facilitating maintenance and upgrades and reducing reliance on single suppliers. Introducing intelligent control systems, utilizing modern industrial control technology, allows for real-time monitoring and precise control of the anti-slip fluid coating process. Such systems can adjust the amount of anti-slip fluid used based on product characteristics and stacking requirements, improving production efficiency and product quality. Utility Model Content

The photoelectric sensor 11, the counter 15, and the touch screen 20 are electrically connected to the PLC 12.

[0025] The number of spraying components 4 is two, and a cylinder mounting block 6 is slidably connected on the guide rail 3 between the two first moving blocks 41 along the X-axis direction. A cylinder 7 is mounted on the cylinder mounting block 6. A paint roller mounting frame 8 is provided below the spraying components 4. A paint roller 9 is installed in the paint roller mounting frame 8. The piston rod 71 of the cylinder 7 faces the middle of the paint roller mounting frame 8, and the lower end of the piston rod 71 is hinged to the paint roller mounting frame 8 through a hinge 10.

[0026] The pressure tank 17 is equipped with a pressure regulating valve 13 and an automatic pressure relief valve 19.

[0027] A solenoid valve 14 is provided on the pipe connecting the pressure tank 17 and the spray gun 45. A self-priming pump 18 and an anti-slip liquid filter tank are provided on the pipe connecting the pressure tank 17 and the anti-slip liquid storage tank 16.

[0028] Both the anti-slip liquid storage tank 16 and the pressure tank 17 are equipped with liquid level sensors.

[0029] The pressure regulating valve 13, the automatic pressure relief valve 19, the solenoid valve 14, the self-priming pump 18, and the liquid level sensor are electrically connected to the PLC 12.

[0030] Working principle: After the sensor detects the product, it transmits the signal to the PLC. The PLC makes a comprehensive judgment on whether the spraying mode needs to be turned on. If it needs to be turned on, it starts the solenoid valve. After the solenoid valve is turned on, the preset compressed air and anti-slip fluid are pushed into the spray gun. The dosage of anti-slip fluid is controlled by the PLC through the opening time of the solenoid valve and the air pressure. The actual amount of anti-slip fluid that can be coated on the product is controlled more precisely by the opening time of the solenoid valve, the pressure of the anti-slip fluid, and the spray gun valve.

[0031] The control method for the anti-slip spraying machine specifically includes the following steps:

[0032] S1: The photoelectric sensor is installed at a key position on the production line. The photoelectric sensor detects whether a product is passing by. When the sensor detects a product, it sends a signal to the PLC. The signal is transmitted through the digital input port DI and is obtained by rising edge triggering.

[0033] S2: The PLC determines whether spraying needs to be started. After receiving the signal from the photoelectric sensor, the PLC will determine whether the current product needs spraying according to the preset program. There are several possible conditions for starting spraying, such as not needing to spray the top layer of the stack to save anti-slip fluid, or not needing to spray the bottom layer of the stack because it is not easy to tip over. If the PLC determines that spraying is needed, it will send a command to open the solenoid valve, and the anti-slip fluid will be sprayed out through the pressure tank and spray gun under pressure; if spraying is not needed, proceed to S5.

[0034] S3: Open the solenoid valve, and the anti-slip liquid will be sprayed out through the pressure tank and spray gun. After a delay, it will be closed. During the spraying process, the pressure of the pressure tank is set between 0.5 bar and 3 bar according to the viscosity. The higher the pressure, the greater the amount of anti-slip liquid sprayed out. When the air pressure is set between 2.8 bar and 3 bar, the opening of the spray gun is controlled by the air pressure. At this time, the spray gun output speed is about 150 ml / min, and the compressed air consumption is about 270 liters / min.

[0035] Depending on the actual needs of spraying, the opening time of the solenoid valve can be set in 1-millisecond intervals. The spraying operation will automatically shut off after the set delay to ensure that the anti-slip liquid is evenly covered on the product.

[0036] The spraying process will automatically shut off after a set delay to ensure that the anti-slip liquid is evenly applied to the product.

[0037] S4: Increment the counter. The system counter increases after each successful spraying operation to record the number of sprays. The counter can also be reset as needed.

[0038] S5: This operation is complete. Return to S1. After the spraying operation is completed, the system will return to step S1 and wait for the next product to pass.

[0039] S6: Operations executed synchronously

[0040] While the main control process is running, the system also performs operations such as liquid level detection, touchscreen data updates, and touchscreen interaction.

[0041] Liquid level detection: The system monitors the anti-slip fluid level in real time to ensure sufficient supply. There are two liquid levels in the system: the anti-slip fluid storage tank and the pressure tank. The anti-slip fluid storage tank is a 20kg low-pressure resistant plastic tank, and its liquid level is set to 3-5 cm from the bottom of the tank. When the anti-slip fluid in the tank is lower than this level, an alarm message indicating insufficient anti-slip fluid will be issued and indicated by a red LED warning light. The pressure tank has a volume between 500 ml and 2 liters. It maintains the internal pressure between 0.5 bar and 3 bar using compressed air and is equipped with an automatic overpressure relief device. When the pressure reaches 10 bar, it will automatically release pressure. The pressure tank has two different liquid levels: low and high. When the anti-slip fluid level is below the low level, a self-priming pump is activated to replenish the anti-slip fluid from the storage tank. When the anti-slip fluid level reaches the high level, the self-priming pump stops operating. The low level sensor is located within 1 cm to 5 cm from the bottom of the pressure tank, and the high level sensor is located within approximately 3 cm to 5 cm from the top of the pressure tank.

[0042] Error checking mechanism: If the liquid level is lower than the preset minimum value, the system will issue a low liquid level alarm and prompt the operator to add anti-slip fluid. If the liquid level remains too low, the system will automatically stop the spraying operation to prevent idling and damage to the equipment.

[0043] Touchscreen data updates: The touchscreen displays current production data and system status for operators to monitor.

[0044] Touchscreen interaction: Operators can set parameters and troubleshoot problems through the touchscreen. Parameters include solenoid valve opening and closing time (typical interval of 10 ms to 300 ms), total spraying time (typical value of 300 to 800 ms), counter reset setting, and sensor delay setting (typical value of 100 to 250 ms).

[0045] Error checking mechanism: The system monitors the touchscreen's interactive response. If the touchscreen is unresponsive or responds incorrectly, the system will record the fault and prompt the operator to check the touchscreen hardware or software.

[0046] Throughout the control process, the introduction of error checking mechanisms significantly improves system reliability and safety. Through real-time monitoring and timely response, the system ensures rapid action in the event of any anomalies, reducing production interruptions and material waste, and improving production efficiency and product quality. With technological advancements, these error checking mechanisms can be further integrated into more complex predictive maintenance systems. By analyzing historical and real-time monitoring data, potential faults can be predicted and maintenance can be performed proactively, further reducing downtime and increasing production efficiency.

[0047] This invention employs a PLC (Programmable Logic Controller) intelligent control system. A PLC is a widely used device in industrial automation, renowned for its high reliability, flexibility, and ease of programming. Through PLC intelligent control, key components in the spraying process—the solenoid valve and the spray gun—can be precisely controlled.

[0048] Solenoid valves are key components for controlling fluid flow. PLC control enables precise control of the spray volume. This control method not only improves spray accuracy but also allows for adjustments to the spray volume over a wider range to adapt to different production needs. For example, in the stacking of chemical products, different product types may require spray coatings of varying thicknesses and shapes; PLC intelligent control can flexibly adjust the opening and closing times and frequencies of the solenoid valves to accommodate these variations.

[0049] As the executing component in the spraying process, the precision of the spray gun directly affects the quality of the coating. The PLC intelligent control system, in conjunction with the conveyor belt movement, precisely controls the spraying speed, pressure, and trajectory, ensuring that the anti-slip liquid is sprayed evenly and accurately to the designated location. This precise control not only improves production efficiency but also reduces material waste and lowers production costs.

[0050] In addition, the PLC intelligent control system also has self-diagnosis and fault detection functions, which can monitor the operating status of the spraying equipment in real time. Once an abnormality is detected, the system will immediately issue an alarm and automatically take corresponding protective measures to prevent equipment damage and production interruption.

[0051] The core of PLC program control lies in its ability to precisely control the opening and closing times of solenoid valves. As a key component in fluid control, the opening and closing state of the solenoid valve directly determines whether anti-slip fluid flows. Through PLC programming, the opening and closing times of the solenoid valve can be precisely set, thereby controlling the flow rate of the anti-slip fluid.

[0052] The pressure inside the pressure tank is another important factor affecting the amount of anti-slip fluid sprayed. The higher the pressure inside the pressure tank, the greater the flow rate of anti-slip fluid through the solenoid valve. Therefore, the PLC program needs to adjust the opening and closing time of the solenoid valve based on the pressure tank pressure data to maintain a stable spray volume.

[0053] As the final component for applying anti-slip liquid, the performance of the spray gun directly affects the uniformity and precision of the coating. The control system of this invention can precisely control the spraying pressure and trajectory, ensuring that the anti-slip liquid is evenly sprayed onto the product surface and avoiding uneven thickness. Simultaneously, the PLC program can adjust the spray gun's trajectory according to the product's shape and requirements, ensuring that the anti-slip liquid is accurately sprayed to the designated locations.

[0054] In summary, by controlling the opening and closing time of the solenoid valve through a PLC program, and in conjunction with the pressure of the pressure tank and the spray gun, accurate control of the coating amount can be achieved. This control method not only improves production efficiency and product quality, but also reduces material waste and production costs.
