Description

Technical Field

[0001] The invention relates to the technical field of spraying equipment, and in particular to an anti-skid liquid spraying machine and a control method thereof. Background Art

[0002] In modern industrial production, the stability and safety of products during stacking and transportation are crucial. In order to ensure that products do not slip or fall during stacking, companies choose to apply anti-slip liquid on the outer surface of product packaging. Although this measure is effective, it also brings challenges and cost issues for spraying equipment.

[0003] First, the equipment used to apply the anti-slip liquid is usually expensive. These devices often require high-precision control and complex mechanical structures to ensure that the anti-slip liquid can be evenly and accurately applied to the surface of the product. Due to the high technical content of these devices, they usually need to be imported from abroad, which not only increases the purchase cost, but also involves a series of additional costs such as transportation and tariffs. In addition, the maintenance and repair of these devices also require professional technical support, which further increases the long-term operating costs.

[0004] Secondly, the amount of anti-slip liquid is also an issue that cannot be ignored. In order to ensure the stability of stacking, it is necessary to apply enough anti-slip liquid on the surface of the product, which often means a large consumption of anti-slip liquid. The increase in the cost of anti-slip liquid directly affects the total cost of the product and reduces the profit margin of the enterprise.

[0005] Furthermore, the single method of controlling the spraying amount is also a problem. Traditional spraying equipment often only provides limited adjustment options and cannot flexibly adjust the amount of anti-slip liquid according to different product characteristics and stacking requirements. This single control method limits production flexibility and product diversity, making it difficult for companies to quickly adjust production strategies when facing market changes.

[0006] Finally, the limited source of equipment parts is also a prominent problem. Since the key parts of these equipment often rely on specific foreign suppliers, once there is a problem in the supply chain, such as supplier suspension of production, transportation interruption, etc., the company's production may face the risk of interruption. This dependence limits the company's autonomy and risk resistance, and affects the company's stable development.

[0007] In order to solve the above problems, enterprises need to seek more economical, flexible and sustainable solutions. The development of new spraying equipment is one of the most important links. By developing new spraying equipment, the equipment cost can be reduced while improving its flexibility and precision. These equipment can be modularly designed to facilitate maintenance and upgrades, reducing dependence on a single supplier. The equipment introduces an intelligent control system and uses modern industrial control technology to develop an intelligent control system to achieve real-time monitoring and precise control of the anti-skid liquid coating process. This system can adjust the amount of anti-skid liquid according to product characteristics and stacking requirements, improving production efficiency and product quality. Summary of the invention

The piston rod 71 of the cylinder 7 faces the middle of the brush roller mounting frame 8 and the lower end of the piston rod 71 is hingedly connected to the brush roller mounting frame 8 through a hinge 10.

[0038] The pressure tank 17 is provided with a pressure regulating valve 13 and an automatic pressure relief valve 19 .

[0039] A solenoid valve 14 is provided on the pipeline connecting the pressure tank 17 and the spray gun 45 , and a self-priming pump 18 and an anti-skid liquid filter barrel are provided on the pipeline connecting the pressure tank 17 and the anti-skid liquid storage barrel 16 .

[0040] Liquid level sensors are provided in the anti-skid liquid storage barrel 16 and the pressure tank 17 .

[0041] 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 .

[0042] Working principle: After the sensor senses the product, it transmits the signal to the PLC. The PLC comprehensively determines whether the spray mode needs to be turned on. If it needs to be turned on, the solenoid valve is started. After the solenoid valve is started, the set compressed air and anti-skid liquid are pushed into the spray gun. The dosage of the anti-skid liquid is comprehensively controlled by the PLC through the time of opening the solenoid valve and the air pressure. The anti-skid liquid that can actually be applied to the product, in addition to the solenoid valve opening time, can also be more accurately controlled by the anti-skid liquid pressure and the spray gun valve.

[0043] The control method of the anti-skid liquid spraying machine comprises the following steps:

[0044] S1: The photoelectric sensor is installed at a key position on the production line. The photoelectric sensor detects whether there is a product passing through. When the sensor detects the product, it sends a signal to the PLC. The signal is transmitted through the digital port DI, and the signal is obtained by rising edge triggering.

[0045] S2: PLC determines whether spraying is required. After receiving the signal from the photoelectric sensor, PLC will determine whether the current product needs spraying according to the preset program. There are many possible conditions for starting spraying, such as saving the use of anti-skid liquid, the top layer of the stack does not need spraying, and the bottom layer of the stack does not easily overturn and does not need spraying. If PLC determines that spraying is required, it will send a command to open the solenoid valve, and the anti-skid liquid will be sprayed out through the pressure tank and spray gun under pressure; if spraying is not required, go to S5;

[0046] S3: Open the solenoid valve, the anti-skid liquid is sprayed out through the pressure tank and the spray gun, and then closed after a delay; 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-skid liquid sprayed; 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 discharge speed is about 150 ml / min, and the compressed air usage is about 270 liters / min;

[0047] According to the actual needs of spraying, the opening time of the solenoid valve can be set in intervals of 1 millisecond, and the spraying operation will automatically close after the set delay to ensure that the anti-skid liquid is evenly covered on the product.

[0048] The spraying operation automatically switches off after a set delay to ensure that the anti-slip liquid covers the product evenly.

[0049] S4: The counter is incremented by one. Each time the spraying operation is successfully completed, the system counter will increase to record the number of spraying times. The counter also has the function of being reset to zero as needed.

[0050] S5: This operation is completed and returns to S1; after the spraying operation is completed, the system will return to step S1 and wait for the next product to pass.

[0051] S6: Operations performed synchronously

[0052] While the main control process is in progress, the system also performs operations such as liquid level detection, touch screen data update and touch screen interaction.

[0053] Liquid level detection: The system will monitor the liquid level of the anti-skid liquid in real time to ensure that the anti-skid liquid is in sufficient supply. There are two liquid levels in the system, namely the anti-skid liquid storage barrel and the pressure tank. The anti-skid liquid storage barrel uses a 20kg low-pressure resistant plastic barrel, and its liquid level is set to 3 to 5 cm from the bottom of the barrel. When the anti-skid liquid in the barrel is lower than this liquid level, an alarm message of insufficient anti-skid liquid is issued, and a red LED warning light is used to prompt. The volume of the pressure tank is between 500 ml and 2 liters. The pressure in the tank is maintained between 0.5 bar and 3 bar by compressed air. At the same time, an overpressure automatic pressure relief device is provided. When the pressure reaches 10 bar, it will automatically release the pressure. The liquid level of the pressure tank is divided into two different states: low liquid level and high liquid level. When the anti-skid liquid is lower than the low liquid level, the self-priming pump is started to replenish the anti-skid liquid from the anti-skid liquid storage barrel. When the anti-skid liquid reaches the high liquid level, the self-priming pump stops running. The low liquid level sensor is set within a range of 1 cm to 5 cm from the bottom of the pressure tank, and the high liquid level is set within a range of about 3 cm to 5 cm from the top of the pressure tank.

[0054] Error checking mechanism: If the liquid level is lower than the preset minimum value, the system will issue a low level alarm and prompt the operator to add anti-skid fluid. If the liquid level continues to be too low, the system will automatically stop the spraying operation to prevent idling and damage to the equipment.

[0055] Touch screen data update: The touch screen will display current production data and system status for operators to monitor.

[0056] Touch screen interaction: Operators can use the touch screen to set parameters and troubleshoot troubleshooting. Parameters include solenoid valve opening and closing time (typical intervals are 10 milliseconds to 300 milliseconds), total spraying time (typical values ​​are 300 to 800 milliseconds), counter reset settings, and sensor delay settings (typical values ​​are 100 to 250 milliseconds).

[0057] Error checking mechanism: The system monitors the interactive response of the touch screen. If the touch screen does not respond or responds incorrectly, the system will record the fault and prompt the operator to check the touch screen hardware or software.

[0058] The introduction of error checking mechanisms throughout the control process has greatly improved the reliability and safety of the system. Through real-time monitoring and timely response, the system can ensure that measures can be taken quickly when any abnormality occurs, reduce production interruptions and material waste, and improve production efficiency and product quality. With the advancement of technology, these error checking mechanisms can be further integrated into more complex predictive maintenance systems. By analyzing historical data and real-time monitoring data, potential failures can be predicted and maintenance can be performed in advance, thereby further reducing downtime and improving production efficiency.

[0059] The present invention adopts a PLC (Programmable Logic Controller) intelligent control system. PLC is a device widely used in the field of industrial automation, and is well-known for its high reliability, flexibility and easy programming. Through PLC intelligent control, the key components in the spraying process, the solenoid valve and the spray gun, can be precisely regulated.

[0060] The solenoid valve is a key component for controlling fluid flow. Through PLC control, precise control of the spraying amount flow can be achieved. This control method not only improves the accuracy of spraying, but also allows the spraying amount to be adjusted within a larger range to meet different production needs. For example, in the process of chemical product stacking, different product types may require spray layers of different thicknesses and shapes, and PLC intelligent control can flexibly adjust the opening and closing time and frequency of the solenoid valve to adapt to these changes.

[0061] The spray gun is the executive component in the spraying process, and its accuracy directly affects the quality of the spraying. The PLC intelligent control system can combine the movement of the conveyor belt to accurately control the spraying speed, spraying pressure and spraying trajectory to ensure that the anti-skid liquid is sprayed evenly and accurately to the designated position. This precise control not only improves production efficiency, but also reduces material waste and reduces production costs.

[0062] 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.

[0063] The core of PLC program control is that it can accurately control the opening and closing time of the solenoid valve. As a key component of fluid control, the opening and closing state of the solenoid valve directly determines whether the anti-skid fluid flows. Through the PLC program, the opening and closing time of the solenoid valve can be accurately set to control the flow of the anti-skid fluid.

[0064] The pressure of the pressure tank is another important factor affecting the spraying amount. The greater the pressure in the pressure tank, the greater the flow of anti-skid fluid through the solenoid valve. Therefore, the PLC program needs to adjust the switching time of the solenoid valve according to the pressure data of the pressure tank to keep the spraying amount stable.

[0065] The performance of the spray gun, as the final component for coating the anti-skid liquid, directly affects the uniformity and accuracy of the spraying. The control system of the present invention can accurately control the spraying pressure and spraying trajectory to ensure that the anti-skid liquid is evenly sprayed on the product surface to avoid uneven thickness. At the same time, the PLC program can also adjust the spraying trajectory of the spray gun according to the shape and requirements of the product to ensure that the anti-skid liquid can be accurately sprayed to the specified position.

[0066] In summary, by controlling the on / off time of the solenoid valve through the PLC program, and coordinating the pressure of the pressure tank and the spray gun, the spraying amount can be accurately controlled. This control method not only improves production efficiency and product quality, but also reduces material waste and production costs.
