Description

Technical Field

[0001] This utility model relates to the field of water-based coating production technology, and in particular to an automatic water-based coating filling device. Background Technology

[0002] Water-based coatings are coating systems that use water as a solvent or dispersion medium. Through emulsion polymerization, dispersion, or dissolution technologies, resins, pigments, additives, and other components are uniformly dispersed in water to form a stable suspension or solution system. Compared to traditional solvent-based coatings, water-based coatings significantly reduce VOC (volatile organic compound) emissions, meeting environmental regulations.

[0003] During the production and filling process of water-based coatings, sedimentation occurs when the coatings are stored in large storage tanks, resulting in inconsistent concentrations of the extracted coatings during the filling process. Therefore, we propose an automatic filling device for water-based coatings to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the existing technology that water-based coatings will precipitate when stored in large storage tanks, resulting in inconsistent concentrations of the water-based coatings extracted during the filling process. Therefore, this invention proposes an automatic water-based coating filling device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic water-based paint filling device includes a storage tank, a drive shaft extending through the top of the storage tank, and a stirring ring fixedly connected to the bottom end of the drive shaft. The device also includes:

[0007] The power mechanism, installed on top of the storage tank, is used to drive the drive shaft to rotate and move longitudinally.

[0008] The conveying mechanism includes a conveying pump and a suction assembly, wherein the suction assembly is fixed to the top of the stirring ring and connected to the conveying pump via a corrugated hose;

[0009] The power mechanism drives the stirring ring to rotate and reciprocate longitudinally via a transmission shaft, and the suction component moves with the stirring ring to extract coatings at different depths in the storage tank.

[0010] In one possible design, the power mechanism includes:

[0011] The output shaft of the variable frequency motor is fixedly connected to the top of the drive shaft;

[0012] The reciprocating screw rotates synchronously with the drive shaft via a belt assembly. The slip ring on the reciprocating screw is fixed to the side wall of the storage tank, causing the drive shaft to move longitudinally back and forth.

[0013] In one possible design, the belt component includes:

[0014] Two synchronous pulleys are fixed to the drive shaft and the reciprocating lead screw, respectively;

[0015] A timing belt is fitted onto two timing pulleys.

[0016] In one possible design, the attraction component includes:

[0017] An annular box is fixed to the top of the stirring ring, and an annular cover plate is rotatably connected inside it.

[0018] Multiple straws are welded at equal intervals to the side wall of the annular box and extend into the storage tank;

[0019] One end of the bend is fixed to the annular cover plate, and the other end is connected to the delivery pump through a corrugated hose.

[0020] In one possible design, a sliding plate is fixed to the bend, and a slide rail is provided on the inner wall of the storage tank. The sliding plate and the slide rail slide together to limit the rotation of the bend.

[0021] In one possible design, the conveying mechanism further includes:

[0022] A support pipe is fixed to the side wall of the storage tank, and a discharge pipe is slidably connected inside it;

[0023] Positioning bolts, threaded onto the side wall of the support pipe, are used to fix the height of the discharge pipe.

[0024] In one possible design, the variable frequency motor is fixed to the top of the storage tank by a connecting plate, and the output shaft is coaxially welded to the transmission shaft.

[0025] In this application, the technical solution allows the produced water-based coating to be placed into a storage tank. When filling the water-based coating, the height of the discharge pipe is first adjusted according to the height of the packaging barrel to align with the inlet of the packaging barrel. Then, the discharge pipe is positioned by turning the positioning bolt. Next, the variable frequency motor is started to drive the drive shaft to rotate, which in turn drives the stirring ring to rotate. This mixes and stirs the water-based coating in the storage tank, preventing sedimentation when filling the water-based coating. The rotation of the drive shaft also drives the connected synchronous pulley to rotate. Through the transmission of the synchronous belt and another synchronous pulley, the reciprocating screw rotates synchronously. When the reciprocating screw rotates, it can perform longitudinal reciprocating motion through the transmission action of the slip ring. Therefore, the transmission through the connecting plate can drive the transmission shaft to perform longitudinal reciprocating motion, so that the stirring ring can rotate in the storage tank and perform longitudinal reciprocating motion at the same time, so as to fully mix and stir the water-based paint in the storage tank, thereby preventing the paint from settling. Then, the delivery pump is started, so that the water-based paint is sucked into the annular box through multiple suction pipes. After that, the water-based paint can be transported to the packaging barrel through the bend pipe, corrugated hose, delivery pump, support pipe and discharge pipe. As the multiple suction pipes move and rotate longitudinally with the stirring ring, they can easily attract water-based paint at different depths, maintaining the uniformity of water-based paint filling.

[0026] Beneficial effects: In this utility model, the automatic water-based coating filling equipment can drive the transmission shaft to rotate by starting the variable frequency motor through the power mechanism. At this time, it can drive the stirring ring to rotate, thereby realizing the mixing and stirring of the water-based coating placed in the storage tank, preventing the water-based coating from settling when it needs to be filled. When the transmission shaft rotates, it can drive the moving component to operate, thereby driving the connecting plate to move longitudinally. At this time, the transmission shaft can drive the stirring ring to move longitudinally, so as to uniformly mix and stir the water-based coating.

[0027] In this utility model, the automatic water-based coating filling equipment, through the conveying mechanism, can attract water-based coatings of different depths in the storage tank when the suction component moves longitudinally with the stirring ring and the conveying pump is started. Then, through the corrugated hose and the conveying pump, the water-based coatings can be conveyed to the support pipe and then discharged from the discharge pipe. The height of the discharge pipe can be adjusted to accommodate packaging barrels of different heights. After the height of the discharge pipe is adjusted, the discharge pipe is positioned by turning the positioning bolt, thereby achieving stable delivery of water-based coatings.

[0028] This invention enables the water-based coating to be thoroughly mixed and stirred in the storage tank during the filling process, thereby avoiding the problem of sedimentation and maintaining the uniformity of the water-based coating concentration during filling. Attached Figure Description

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0037] Example 1: Refer to Figure 1-5A filling device includes a storage tank 1, with a drive shaft 2 extending through the top of the storage tank 1. A stirring ring 3 is welded to the bottom of the drive shaft 2 for stirring water-based coatings within the storage tank 1. A power mechanism is mounted at the top of the drive shaft 2 and connected to one side of the storage tank 1, enabling the drive shaft 2 to move longitudinally and rotate. The filling device also includes a conveying mechanism installed on one side of the top of the storage tank 1, extending its bottom into the storage tank 1 and connected to the stirring ring 3. This mechanism allows the water-based coating to be extracted during stirring. One side of the conveying mechanism is connected to the other side of the storage tank 1.

[0038] The power mechanism includes a connecting plate 4. A variable frequency motor 9 is bolted to one side of the top of the connecting plate 4. The output shaft of the variable frequency motor 9 extends below the connecting plate 4 and is welded to the top of the transmission shaft 2. The connecting plate 4 connects to a moving component, which is connected to one side of the storage tank 1 and also to the transmission shaft 2. Starting the variable frequency motor 9 drives the transmission shaft 2 to rotate, which in turn drives the stirring ring 3 to rotate, thus mixing and stirring the water-based coating in the storage tank 1 and preventing the water-based coating from settling. When the transmission shaft 2 rotates, it drives the moving component to move, causing the connecting plate 4 to move longitudinally. This, in turn, causes the stirring ring 3 to move longitudinally, achieving uniform mixing and stirring of the water-based coating.

[0039] The moving component includes a reciprocating screw 5 rotatably connected to a connecting plate 4. A slip ring 6, which mates with a spiral groove, is fitted onto the reciprocating screw 5 and welded to the top of one side of the storage tank 1. The reciprocating screw 5 is connected to the drive shaft 2 via the same belt assembly. When the drive shaft 2 rotates, it drives the reciprocating screw 5 to rotate via the belt assembly. Under the transmission of the slip ring 6, the reciprocating screw 5 moves longitudinally back and forth. This longitudinal reciprocating motion is transmitted through the connecting plate 4, causing the drive shaft 2 to move longitudinally back and forth. Simultaneously, the stirring ring 3 rotates within the storage tank 1 and moves longitudinally back and forth, thoroughly mixing and stirring the water-based coating to prevent sedimentation.

[0040] The belt assembly includes two synchronous pulleys 7, which are fixedly mounted on the drive shaft 2 and the reciprocating screw 5 respectively via key connections. The two synchronous pulleys 7 are connected by the same synchronous belt 8. When the drive shaft 2 rotates, it drives the connected synchronous pulleys 7 to rotate. Under the transmission cooperation of the synchronous belt 8 and the other synchronous pulley 7, the reciprocating screw 5 rotates synchronously, dispersing the driving force of the variable frequency motor 9 and improving power utilization.

[0041] The conveying mechanism includes a conveying pump 10 bolted to one side of the top of the storage tank 1. The suction end of the conveying pump 10 extends into the storage tank 1 and is fixedly connected to a corrugated hose 11. A bend 12 is fixedly connected to the bottom end of the corrugated hose 11, and one end of the bend 12 is connected to a suction assembly, which is mounted on top of the stirring ring 3. The discharge end of the conveying pump 10 is fixedly connected to a support pipe 18, one end of which extends to the other side of the storage tank 1 and is fixedly connected. A discharge pipe 19 is tightly slidably connected inside the support pipe 18. A threaded positioning bolt 20 is threaded through the inner wall of the bottom of one side of the support pipe 18 for positioning and braking the discharge pipe 19. When the suction assembly moves longitudinally with the stirring ring 3, the conveying pump 10 is activated. The suction assembly can attract water-based paint of different depths in the storage tank 1, convey it through the corrugated hose 11 and the conveying pump 10 to the support pipe 18, and then discharge it through the discharge pipe 19. The height of the discharge pipe 19 is adjustable to accommodate packaging barrels of different heights. After adjustment, the positioning bolt 20 is turned to fix the position, achieving stable conveying of water-based paint.

[0042] This application can be used in the field of water-based coating production technology, or in other fields applicable to this application.

[0043] Example 2: Reference Figure 3 and 5 An improvement upon Embodiment 1: An automatic water-based paint filling device, applied to the field of water-based paint production technology, includes an aperture assembly comprising an annular box 15 mounted on a drive shaft 2, the annular box 15 being fixedly connected to the top of a stirring ring 3, an annular cover plate 17 rotatably connected inside the annular box 15, a bent pipe 12 extending one end into the annular box 15 and fixedly connected to the annular cover plate 17, and multiple suction pipes 16 welded at equal intervals to the inner side wall of the annular box 15, one end of each suction pipe 16 extending into a storage tank 1 and fixedly connected to the top of the stirring ring 3. The annular box 15 is rotatably connected to the annular cover plate 17, and the annular box 15 rotates undisturbed with the stirring ring 3. After the delivery pump 10 is started, the multiple suction pipes 16 maintain suction, moving and rotating longitudinally with the stirring ring 3, facilitating the attraction of water-based paint at different depths, and conveying the paint through the suction pipes 16 and the annular box 15 to the bent pipe 12.

[0044] A sliding plate 13 is fixedly mounted on the bent pipe 12, and a slide rail 14 is welded to the inner wall of one side of the storage tank 1. The sliding plate 13 and the slide rail 14 are slidably connected. The longitudinal sliding cooperation of the sliding plate 13 and the slide rail 14 is used to limit the longitudinal sliding of the bent pipe 12, preventing the bent pipe 12 from rotating with the annular box 15 and avoiding the corrugated hose 11 from getting tangled on the drive shaft 2.

[0045] The variable frequency motor 9 can also achieve forward and reverse rotation, so that during the process of extracting water-based coating, the stroke height of the stirring ring 3 can be adjusted according to the change in the height of the water-based coating, thereby ensuring that the multiple suction tubes 16 are always inside the water-based coating.

[0046] However, as is well known to those skilled in the art, the working principles and wiring methods of the variable frequency motor 9 and the delivery pump 10 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
