Technical Field
[0001] This utility model belongs to the technical field of paint filling equipment, specifically relating to a filling machine for paint production. Background Technology
[0002] In the paint production process, filling is a crucial step in accurately filling the packaging containers with paint. Traditional filling machines have the following problems during the filling process:
[0003] ① A large number of air bubbles are easily generated during the filling process. These air bubbles will not only reduce the filling accuracy of the paint, but may also cause unstable pressure inside the paint bucket, affecting subsequent use.
[0004] ②The quantitative dispensing components of traditional filling machines have low precision and cannot accurately control the filling volume, which can easily lead to paint waste or insufficient filling.
[0005] ③ Traditional filling machines lack effective drip protection measures. Paint drips not only contaminate the conveyor belt, but also affect the cleanliness of the production environment.
[0006] ④ The mixing device and conveyor belt design of traditional filling machines are not perfect, and cannot effectively prevent paint sedimentation and paint bucket tipping, which further reduces production efficiency and product quality.
[0007] Therefore, developing a new type of paint filling machine that can solve the above problems is of great practical significance. Summary of the Invention
[0008] To address the aforementioned problems, this utility model discloses a filling machine for paint production. The design of the telescopic baffle effectively prevents paint dripping from contaminating the conveyor belt, ensuring a clean production environment. An ultrasonic defoamer installed between the filling head and the discharge pipe effectively reduces air bubbles generated during the filling process, improving filling accuracy and product quality. Furthermore, a pressure sensor installed on the discharge pipe allows for real-time monitoring of paint pressure, preventing inaccurate filling due to pressure fluctuations.
[0009] To achieve the above objectives, the specific technical solution of this application is as follows:
[0010] A coating production filling machine includes a frame, a storage tank, a conveyor belt, and a control system. The storage tank is located above the frame and is equipped with a liquid level sensor. A metering dispensing component is located below the storage tank, and the conveyor belt is located below the storage tank. A telescopic baffle is located below the metering dispensing component. The metering dispensing component includes a dispensing pipe, the end of which is connected to a filling head. An ultrasonic defoamer is provided between the filling head and the dispensing pipe. A metering pump and a solenoid valve are provided on the dispensing pipe. The telescopic baffle is driven by a drive motor connected to the frame. The drive motor is connected to the baffle body, and position sensors are provided on both sides of the baffle body.
[0011] Based on the above technical features, preferably, the discharge pipe is also equipped with a pressure sensor to detect the pressure of the coating in the discharge pipe and prevent overpressure or underpressure.
[0012] Based on the above technical features, preferably, the storage tank is equipped with a stirring device, which includes a stirring shaft and stirring blades. The stirring shaft is driven by a first motor, and the stirring blades have a spiral structure, which can prevent the coating from settling in the storage tank and ensure the uniformity of the coating.
[0013] Based on the above technical features, preferably, the conveyor belt is provided with guardrails on both sides, and the guardrails are made of lightweight aluminum alloy, which has good corrosion resistance and strength.
[0014] Based on the above technical features, preferably, the height of the guardrail is adjustable to prevent the paint buckets from tipping over during transport.
[0015] Based on the above technical features, the conveyor belt is further provided with multiple positioning devices, each including a positioning block and a cylinder. The cylinder is connected to the positioning block, which is used to fix the position of the paint bucket. The cylinder drives the positioning block to extend and retract, ensuring that the paint bucket remains stable during the filling process.
[0016] Compared with the prior art, the beneficial effects of this application are as follows:
[0017] This application effectively reduces air bubbles generated during the filling process by installing an ultrasonic defoamer between the filling head and the discharge pipe, thus improving filling accuracy and product quality. A pressure sensor on the discharge pipe monitors the paint pressure in real time, preventing inaccurate filling due to pressure fluctuations. A stirring device at the bottom of the storage tank prevents paint sedimentation, ensuring paint uniformity. Adjustable guardrails and positioning devices on both sides of the conveyor belt effectively prevent paint buckets from tipping over during transport, improving production stability. The telescopic baffle design effectively prevents paint dripping from contaminating the conveyor belt, ensuring a clean production environment. In summary, this paint filling machine significantly improves product quality and the cleanliness of the production environment while increasing production efficiency. Attached Figure Description

An ultrasonic defoamer 7 is installed between the filling head and the dispensing pipe. A metering pump 9 and a solenoid valve 10 are installed on the dispensing pipe 6. The metering pump 9 is controlled by frequency conversion to precisely control the amount of paint dispensed. The solenoid valve 10 is used to quickly cut off the paint flow to ensure filling accuracy. The ultrasonic defoamer 7 eliminates air bubbles in the paint through high-frequency vibration, reducing the generation of air bubbles during the filling process. Preferably, a pressure sensor 13 is also installed on the dispensing pipe to detect the pressure of the paint in the dispensing pipe 6 and prevent overpressure or underpressure.
[0026] A telescopic baffle is located below the quantitative dispensing component. The telescopic baffle is driven by a drive motor 12 connected to the frame.

[0035] The ultrasonic defoamer is activated, using high-frequency vibration to eliminate air bubbles in the coating and reduce the generation of air bubbles during the filling process;
[0036] The pressure sensor monitors the coating pressure in the discharge pipe in real time to ensure stable pressure and prevent overpressure or underpressure.
[0037] The filling head pours the paint into the paint bucket, and the filling volume is precisely controlled by a metering pump.
[0038] The solenoid valve closes, the metering pump stops working, and filling is complete.
[0039] The telescopic baffle extends under the control of the drive motor to block any paint drips and prevent contamination of the conveyor belt.
[0040] The telescopic baffle retracts after a certain period of time, and any dripping paint is collected and disposed of, ensuring the cleanliness of the conveyor belt.
