Description

Technical Field

[0001] This utility model relates to the technical field of paint production equipment, and in particular to a quantitative filling device for processing and producing oil-based paints. Background Technology

[0002] In the processing and production of oil-based coatings, quantitative filling is a core step in ensuring product quality consistency and improving production efficiency. Its filling stability directly affects product quality and production benefits. Traditional oil-based coating filling equipment generally suffers from structural design deficiencies, mainly manifested in two key issues: First, traditional equipment often uses a fixed-height discharge structure. During filling, there is a certain gap between the discharge port and the bottom of the container. As the oil-based coating falls from a height, due to its viscosity characteristics and the impact force of the fall, it is prone to splashing, which contaminates the container opening and outer wall. Second, due to the inherent characteristics of oil-based coatings—high viscosity and poor flowability—coating residue may remain on the inner wall of the discharge port after filling. Traditional equipment lacks an effective residue treatment mechanism, causing this residue to drip onto the outside of the container, the placement platform, or the production floor. This not only directly wastes valuable coating raw materials but also seriously pollutes the production environment. Furthermore, it significantly increases the workload and manpower and material costs of subsequent cleaning and maintenance, hindering the continuity and economy of the production process. Utility Model Content

[0003] The present invention aims to at least partially solve one of the problems existing in the existing related technologies. To this end, the present invention proposes a quantitative filling device for the processing and production of oil-based coatings.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A quantitative filling device for oil-based paint processing includes a placement platform for placing a material container and a column located on one side of the placement platform. A lifting seat is movable up and down at the upper end of the column, and a lifting drive mechanism drives the lifting seat to move up and down. A material pipe is provided at the upper end of the lifting seat. The rear end of the material pipe is connected to a storage tank via a hose, and the front end is provided with a discharge pipe. The discharge pipe is vertically downward and has a discharge port at its lower end. A hinge seat is provided on one side of the lower end of the discharge pipe, and a receiving shell is hinged to the hinge seat. The receiving shell can swing below the discharge port or swing outward away from the discharge port. The quantitative filling device also includes a transmission assembly. When the discharge pipe descends with the lifting seat into the material container for filling, the transmission assembly drives the receiving shell to swing outward away from the discharge port. When the discharge pipe rises with the lifting seat to complete the filling operation, the transmission assembly drives the receiving shell to swing below the discharge port.

[0005] In some embodiments, the hinge seat is located on the rear side of the lower end of the discharge pipe, and the receiving shell is provided with a hinge shaft, which is rotatably mounted on the hinge seat.

[0006] In some embodiments, the transmission assembly includes a torsion spring disposed on the hinge shaft. One end of the torsion spring is connected to the hinge seat, and the other end is connected to the receiving shell. The torsion spring keeps the receiving shell away from the discharge port. An inclined extension plate is also disposed on the hinge shaft, and a fixed baffle is disposed on the column. When the extension plate rises with the receiving shell, the extension plate can abut against the fixed baffle, thereby driving the hinge shaft to rotate and causing the receiving shell to swing below the discharge port.

[0007] In some embodiments, a limiting flange is also provided on the hinge seat. When the receiving shell is driven to swing outward by the torsion spring, the limiting flange can limit the swing angle of the receiving shell, so that the receiving shell maintains the shape of swinging outward away from the discharge port.

[0008] In some embodiments, the lifting drive mechanism includes a cylinder mounted on the column, and the piston rod of the cylinder is connected to the lifting seat.

[0009] In some embodiments, the column is a hollow structure, the cylinder is disposed inside the hollow structure, the lower end of the lifting seat is an open structure, and the lower opening of the lifting seat is fitted onto the column.

[0010] In some embodiments, the placement platform is a roller conveyor line.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. First, the lifting drive mechanism drives the discharge pipe to descend synchronously with the lifting seat, allowing the discharge pipe to penetrate deep into the material barrel for filling operations. This significantly shortens the distance between the discharge port and the paint surface, fundamentally preventing splashing of oil-based paint due to height differences during the descent, thus preventing contamination of the barrel opening and outer wall.

[0012] 2. With the help of the receiving shell and transmission components that are linked to the lifting action of the discharge pipe, when the discharge pipe rises after filling, the receiving shell can automatically swing to below the discharge port to accurately catch the residual oily paint at the discharge port. This solves the problem of residual paint dripping in traditional devices, which not only reduces raw material waste and lowers production costs, but also avoids pollution of the production environment and significantly reduces the workload and cost of subsequent cleaning and maintenance.

[0013] 3. The swinging motion of the receiving shell is fully automatically linked with the lifting motion of the lifting seat through the transmission component. There is no need for manual intervention to switch the receiving position, which simplifies the operation process and avoids errors that may be caused by manual operation. Moreover, the transmission component works ingeniously with the existing lifting drive mechanism, eliminating the need for additional complex drive units. The structure is compact and the manufacturing cost is low. Attached Figure Description

[0020] The following detailed description provides various embodiments or examples for implementing this utility model. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of this utility model and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0021] like Figures 1-6The illustrated quantitative filling device for oil-based paint processing includes a placement platform 1 for placing a material barrel 10 and a column 2 located on one side of the placement platform 1. A lifting seat 3 is movable vertically at the upper end of the column 2, along with a lifting drive mechanism for driving the lifting seat 3 to move up and down. A material pipe 4 is provided at the upper end of the lifting seat 3. The rear end of the material pipe 4 is connected to a storage tank via a hose 6, and the front end is provided with a discharge pipe 5. The discharge pipe 5 is vertically downward and has a discharge port 7 at its lower end. The device is equipped with a hinged seat 8, on which a receiving shell 9 is hinged. The receiving shell 9 can swing below the discharge port 7 or swing outward away from the discharge port 7. The quantitative filling device also includes a transmission component. When the discharge pipe 5 follows the lifting seat 3 down into the material tank 10 for filling, the transmission component can drive the receiving shell 9 to swing outward away from the discharge port 7. When the discharge pipe 5 follows the lifting seat 3 up to complete the filling work, the transmission component can drive the receiving shell 9 to swing below the discharge port 7.

[0022] The core of this oil-based paint quantitative filling device is to achieve automated linkage between the filling operation and the collection of residual paint through the coordinated action of the lifting drive mechanism and the transmission components. The specific workflow is as follows: The container 10 to be filled is placed on the placement platform 1. The lifting drive mechanism is initially in the reset state, at which time the discharge pipe 5 is above the container 10, and the receiving shell 9 swings to below the discharge port 7 under the action of the transmission component to collect any paint residue that may have remained after the previous filling. After the filling program is started, the lifting drive mechanism drives the lifting seat 3 to drive the material pipe 4 and the discharge pipe 5 to descend synchronously until the discharge pipe 5 reaches a suitable position inside the container 10. During this descent, the transmission component moves synchronously, driving the receiving shell 9 to swing outward around the hinge seat 8 through mechanical linkage, away from the discharge port 7, to avoid interfering with the paint filling. Subsequently, the oily paint in the storage tank is precisely injected into the container 10 through the hose 6, material pipe 4, and discharge pipe 5 from the discharge port 7. The discharge port 7 rises along with the lifting seat 3 while the paint is being injected, completing the quantitative filling. After quantitative filling is completed, the lifting drive mechanism drives the lifting seat 3 to raise and reset the discharge pipe 5 to the highest point. At this time, the transmission component drives the receiving shell 9 to swing inward around the hinge seat 8 and return to below the discharge port 7. When the discharge pipe 5 rises to the highest point, the high viscosity coating remaining in the discharge port 7 drips into the receiving shell 9, preventing it from dripping onto the outside of the material bucket 10 or the production environment.

[0023] In this invention, the hinge seat 8 is located on the rear side of the lower end of the discharge pipe 5, and the receiving shell 9 is provided with a hinge shaft 21, which is rotatably mounted on the hinge seat 8. The transmission assembly includes a torsion spring 31 provided on the hinge shaft 21, one end of which is connected to the hinge seat 8, and the other end is connected to the receiving shell 9. The torsion spring 31 keeps the receiving shell 9 away from the discharge port 7. An inclined extension plate 32 is also provided on the hinge shaft 21. A fixed baffle 33 is provided on the column 2. When the extension plate 32 rises with the receiving shell 9, the extension plate 32 can abut against the fixed baffle 33, thereby driving the hinge shaft 21 to rotate, causing the receiving shell 9 to swing below the discharge port 7. A limiting flange 41 is also provided on the hinge seat 8. When the receiving shell 9 swings outward by the torsion spring 31, the limiting flange 41 can limit the swing angle of the receiving shell 9, so that the receiving shell 9 maintains the shape of swinging outward away from the discharge port 7.

[0024] Specifically, the hinge seat 8 is fixed to the rear side of the lower end of the discharge pipe 5, and the receiving shell 9 is rotatably mounted on the hinge seat 8 through the hinge shaft 21; one end of the torsion spring 31 in the transmission assembly is connected to the hinge seat 8 and the other end is connected to the receiving shell 9. Under the elastic force of the torsion spring 31, the receiving shell 9 is continuously pushed away from the discharge port 7, and the swing angle is limited by the limiting flange 41 on the hinge seat 8, so that the receiving shell 9 can stably maintain the initial shape away from the discharge port 7, and avoid interfering with the subsequent filling preparation.

[0025] After the filling program is started, the lifting drive mechanism drives the lifting seat 3 to move the discharge pipe 5, hinge seat 8, receiving shell 9 and hinge shaft 21 down synchronously until the discharge pipe 5 is deep into the material barrel 10. During this process, the extension plate 32 on the hinge shaft 21 moves down synchronously with the receiving shell 9 and does not contact the fixed baffle 33 on the column 2. The elastic force of the torsion spring 31 continues to act, and the receiving shell 9 is kept away from the discharge port 7 under the constraint of the limiting flange 41, ensuring that the paint is smoothly injected into the material barrel 10 through the discharge port 7 without structural interference.

[0026] The lifting drive mechanism drives the lifting seat 3 to move the discharge pipe 5, receiving shell 9 and extension plate 32 to rise synchronously. When it rises to the preset height, the inclined extension plate 32 abuts against the fixed baffle 33 on the column 2. As the lifting seat 3 continues to rise, the fixed baffle 33 generates a downward resisting force on the extension plate 32, forcing the extension plate 32 to drive the hinge shaft 21 to rotate around the hinge seat 8, thereby overcoming the elastic force of the torsion spring 31 and driving the receiving shell 9 to swing inward. Until the receiving shell 9 swings precisely below the discharge port 7 to receive the oily paint remaining in the discharge port 7 during the rising process. After the material tank 10 is replaced, when the lifting seat 3 descends again, the extension plate 32 and the fixed baffle 33 disengage, the torsion spring 31 recovers its elastic deformation, and drives the hinge shaft 21 to rotate in the opposite direction. Under the action of the torsion spring 31 and the limiting action of the limiting flange 41, the receiving shell 9 returns to the shape away from the discharge port 7, waiting for the next round of filling.

[0027] See Figure 1 , Figure 3 , Figure 5 As shown, the lifting drive mechanism includes a cylinder 51 mounted on the column 2. The piston rod of the cylinder 51 is connected to the lifting seat 3. The column 2 is a hollow structure, and the cylinder 51 is located inside the hollow structure. The lower end of the lifting seat 3 is an open structure, and the lower opening of the lifting seat 3 is fitted onto the column 2.

[0028] Therefore, the column 2 adopts a hollow structure, and the cylinder 51 is installed inside the hollow structure to ensure that the cylinder 51 is not exposed. The lower end of the lifting seat 3 is designed with an open structure, and the lower opening is fitted onto the outside of the column 2, forming a nested structure with the column as the core and the lifting seat as the sleeve. This avoids the cylinder 51 being exposed and occupying extra production space, and at the same time prevents oily paint splashes, dust and other impurities from adhering to the surface of the cylinder 51, reducing the failure of the cylinder 51 due to contamination.

[0029] In this invention, the placement platform 1 is a roller conveyor line.

[0030] Once the placement platform 1 is designed as a roller conveyor line, it can form an automated connection with upstream and downstream processes (such as empty barrel loading, post-filling capping / palletizing). Empty barrels 10 are automatically transported to the filling station via the roller conveyor line, and after filling, they can be automatically transported to the next process. There is no need for manual handling of barrels 10, which completely breaks the intermittent production mode of traditional fixed placement platforms where one barrel is filled and then moved. It realizes continuous operation of oil-based paint filling, which is especially suitable for large-scale production scenarios and significantly increases the total filling volume per unit time.
