Description

Technical Field

[0001] This utility model relates to the field of coating production technology, specifically to a feeding device for the production of water-based epoxy coatings. Background Technology

[0002] As is well known, the production process of waterborne epoxy coatings requires extremely high precision in material proportioning during the feeding stage, as deviations in material quantity can directly affect the performance and quality of the coating. However, traditional feeding devices currently on the market have many shortcomings. On the one hand, traditional devices often use simple pipeline conveying or manual dumping methods, which are prone to material blockage and uneven conveying during the process, leading to unstable feeding rhythms and affecting subsequent production processes. On the other hand, the weighing and detection functions of existing devices are incomplete, lacking accurate real-time weighing equipment, making it difficult to accurately control the weight of the fed materials. This often results in the feeding amount exceeding or falling short of the production formula requirements, failing to meet the stringent material proportioning requirements of waterborne epoxy coating production. Therefore, it is necessary to propose a solution to this technical problem. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4This utility model relates to a feeding device for the production of water-based epoxy coatings, comprising a conveying pipe 1 and an installation cylinder 2. The conveying pipe 1 is equipped with a feeding mechanism and a screw conveying mechanism. One end of the conveying pipe 1 is provided with a curved pipe 3, and a first electric valve 4 is provided on the curved pipe 3. A support mechanism is provided between the installation cylinder 2 and the first electric valve 4. An annular weighing device 5 is provided inside the installation cylinder 2. A temporary storage cylinder 6 is provided at the top of the annular weighing device 5. A second electric valve 7 and a discharge pipe 8 are provided on the temporary storage cylinder 6. The discharge pipe 8 passes through the center of the annular weighing device 5 and extends to the bottom of the installation cylinder 2. The top of the installation cylinder 2 is connected to the first electric valve 4. A sealing sleeve 9 is provided between the electric valve 4 and the sealing sleeve 9, and an elastic sleeve 10 is provided between the temporary storage cylinder 6 and the sealing sleeve 9. In this embodiment, the conveying pipe 1 serves as the main channel for material conveying. The feeding mechanism on it enables the introduction of materials for the production of water-based epoxy coatings. The screw conveying mechanism uses the screw propulsion action to stably convey the materials in the conveying pipe 1 to the curved pipe 3 at one end. The first electric valve 4 on the curved pipe 3 can control whether the materials enter the temporary storage cylinder 6 on the mounting cylinder 2. Opening the first electric valve 4 allows the materials for the production of water-based epoxy coatings to enter the temporary storage cylinder 6. The support mechanism provides a stable connection and support between the first electric valve 4 and the mounting cylinder 2, ensuring the stability of the device structure. The annular weighing device 5 inside the mounting cylinder 2 is the core detection component. A temporary storage cylinder 6 is located at the top of the annular weighing device 5 and is used to temporarily store materials conveyed from the curved pipe 3. The annular weighing device 5 can detect the weight change of the material in the temporary storage cylinder 6 in real time. The second electric valve 7 on the temporary storage cylinder 6 controls the material to be discharged through the discharge pipe 8. The discharge pipe 8 passes through the center of the annular weighing device 5 and extends to the bottom of the mounting cylinder 2, ensuring that the material discharge path does not interfere with the weighing detection. When the detected weight is within the required feeding weight range, the first electric valve 4 is closed and the second electric valve 7 is opened, allowing the material for water-based epoxy coating production to be fed into the water-based epoxy coating production equipment through the discharge pipe 8, achieving precise quantitative feeding. Then, the second electric valve 7 is closed and the first electric valve 4 is opened, facilitating the next weighing and quantitative feeding operation. The top of the mounting cylinder 2 and the first electric valve 7... The sealing sleeve 9 between the electric valve 4 and the elastic sleeve 10 between the temporary storage cylinder 6 and the sealing sleeve 9 can reduce the interference of external factors on the temporary storage cylinder 6, ensuring the accurate weighing of the annular weighing device 5. The annular weighing device 5 weighs the material in the temporary storage cylinder 6 in real time. Combined with the on / off control of the first electric valve 4 and the second electric valve 7, it can accurately control the feeding amount and meet the material ratio requirements of water-based epoxy coating production. The sealing sleeve 9 and the elastic sleeve 10 play a sealing role, preventing external dust from entering the temporary storage cylinder 6 and preventing dust generated by the materials used in the production of water-based epoxy coating from being discharged, which would affect the working environment of personnel. The cylinder 2 is supported by the support mechanism, so that the annular weighing device 5 can only calculate the weight of the temporary storage cylinder 6, the sealing sleeve 9 and the elastic sleeve 10, and then obtain the weighing detection of the materials used in the production of water-based epoxy coating by removing the weight.

[0022] To stably transport materials for the production of water-based epoxy coatings, in this solution, the spiral conveying mechanism includes a drive motor 11 and a spiral shaft 12. The drive motor 11 is installed at one end of the conveying pipe 1, and the spiral shaft 12 is located inside the conveying pipe 1. The output end of the drive motor 11 is connected to one end of the spiral shaft 12. By controlling the output end of the drive motor 11 to rotate the spiral shaft 12, the spiral shaft 12 rotates in the conveying pipe 1, thereby enabling the stable and uniform transport of materials for the production of water-based epoxy coatings through the spiral.

[0023] To securely support the mounting cylinder 2, in this design, the support mechanism includes support rods 13. Connecting frames are provided between the support rods 13 and both the first electric valve 4 and the mounting cylinder 2. Multiple support rods 13 are arranged in a circular array. This circular array layout ensures that the supporting force is evenly distributed at the connection between the first electric valve 4 and the mounting cylinder 2, forming a stable support structure.

[0024] In order to facilitate the feeding of materials for waterborne epoxy coating production into the conveying pipe 1, in this solution, the feeding mechanism includes a feeding pipe 14, which is installed at the top of the conveying pipe 1. The feeding pipe 14 provides a clear entry path for the materials, realizes the directional introduction of materials into the conveying pipe 1, and ensures that the materials for waterborne epoxy coating production can smoothly enter the conveying process.

[0025] To improve feeding efficiency, in this solution, the top end of the feeding pipe 14 is provided with a feeding hopper 15. The feeding hopper 15 increases the receiving area of ​​the material, making it easier to add materials, reducing spillage and waste during the material addition process, and improving feeding efficiency. It is especially suitable for batch material feeding and reduces the difficulty of operation.

[0026] To improve the control precision of the screw shaft 12, in this design, the drive motor 11 is a servo motor. A servo motor has precise speed and position control capabilities, and can accurately adjust its output speed according to the control signal, thereby controlling the rotational speed of the screw shaft 12. The precise control characteristics of the servo motor allow for precise adjustment of the conveying speed of the screw conveyor mechanism, thus achieving precise control of the material conveying volume. By adjusting the speed of the servo motor, different feeding volume requirements can be flexibly adapted, improving the adaptability of the device to different production formulas and further enhancing the feeding precision.
