[0001] This utility model relates to the technical field of water-based paint pretreatment devices, and in particular to a water-based paint pretreatment device. Background Technology

[0002] All coatings that use water as a solvent or dispersion medium can be called water-based paints. Water-based paints are harmless to the human body, do not pollute the environment, and have the characteristics of full, crystal clear, and good flexibility. However, water-based paints need to be processed by equipment before use so that their characteristics can be fully utilized.

[0003] Chinese Patent No. CN217854940U discloses a water-based paint pretreatment device, comprising: a housing and a protective door. Supports are installed on both sides of the housing, an inlet is installed on the top of the housing, and an outlet is installed on the bottom of the housing. The protective door is hinged to one side of the housing. A filter screen frame is provided at the bottom of the inlet, and connecting blocks are installed on both sides of the filter screen frame. The beneficial effect of this water-based paint pretreatment device is that it can drive a turntable to rotate via a rotating motor. The connecting rod and crank are connected by a rotating shaft, which drives the connecting rod to move up and down reciprocally, thereby driving the filter screen frames on both sides to move back and forth. During the movement, the rollers on one side of the filter screen frame slide up and down along the slide groove via a movable spring, thus vibrating and screening the raw materials to prevent impurities from appearing in the water-based paint. This is the characteristic of the water-based paint pretreatment device.

[0004] However, the aforementioned publicly available solutions have the following shortcomings: existing water-based paint pretreatment devices cannot effectively and fully stir the paint, and cannot remove impurities from the paint during the stirring process, which affects the subsequent use of the paint. Utility Model Content

[0005] The purpose of this invention is to address the problem in the prior art that it is impossible to fully stir the coating and remove impurities from the coating, and to propose a water-based paint pretreatment device.

[0006] The technical solution of this utility model is: a water-based paint pretreatment device, including a treatment cylinder; and further comprising:

[0009] And a removal ring, which is set on the removal mechanism. A protective cylinder is slidably set on the outer side of the removal ring. The inner side of the removal ring is in contact with the outer side of the treatment cylinder. The removal ring can be moved up and down in a cycle under the drive of the removal mechanism, thereby pushing the impurities that fall above the removal ring out of the treatment cylinder. The coating flows back into the treatment cylinder through the filter holes on the removal ring, and the impurities slide off the inclined surface of the removal ring to the outside.

A connecting frame is provided on the outer side of the sliding ring, and an insert rod is slidably arranged on the connecting frame. A spring is provided on the outer side of the insert rod.

[0020] Compared with the prior art, this utility model has the following beneficial technical effects: By setting up the impurity removal mechanism and the stirring mechanism, the motor drives the stirring blade to stir the coating.

[0026] Example 1

[0027] like Figures 1-4 As shown, the present invention proposes a water-based paint pretreatment device, comprising a treatment cylinder 1, a stirring mechanism, a dirt removal mechanism, and a dirt removal ring 303.

[0028] The stirring mechanism is located inside the processing cylinder 1 and is used to tumble the water-based coating while stirring it.

[0029] The impurity removal mechanism is located on the outside of the treatment cylinder 1 and is used to circulate and discharge impurities in the water-based coating.

[0030] The impurity removal ring 303 is mounted on the impurity removal mechanism. A protective cylinder 2 is slidably mounted on the outer side of the impurity removal ring 303. The inner side of the impurity removal ring 303 is in contact with the outer side of the processing cylinder 1. The impurity removal ring 303 can move up and down in a cycle under the drive of the impurity removal mechanism, thereby pushing the impurities that fall above the impurity removal ring 303 out of the processing cylinder 1. The coating flows back into the processing cylinder 1 through the filter holes on the impurity removal ring 303, and the impurities slide off the inclined surface of the impurity removal ring 303 to the outside.

[0031] The stirring mechanism includes a rotating assembly and a stirring assembly. The rotating assembly is mounted on the processing cylinder 1 and provides power to the stirring assembly. The stirring assembly is located outside the rotating assembly and is used to stir the coating inside the processing cylinder 1. The rotating assembly includes a motor 401, a rotating shaft 402, and a connecting ring 403. The motor 401 is located at the bottom of the processing cylinder 1, the rotating shaft 402 is located at the output end of the motor 401, and the connecting ring 403 is located outside the rotating shaft 402. The stirring assembly includes a connecting shaft 404, a stirring blade 405, a first bevel gear 406, and a second bevel gear 407. The connecting shaft 404 is located outside the connecting ring 403, and there are three connecting shafts 404. The first bevel gear 406 is located outside the connecting shaft 404, the stirring blade 405 is located on the side of the first bevel gear 406 away from the connecting ring 403, the second bevel gear 407 is located at the bottom of the first bevel gear 406, and a connecting rod 408 is located at the bottom of the second bevel gear 407. A connecting rod 409 is provided at the bottom of 08, and a conical platform 410 is provided at the bottom inner side of the processing cylinder 1. The starting motor 401 drives the rotating shaft 402 to rotate, and the rotating shaft 402 drives the connecting ring 403 to rotate. The connecting ring 403 drives the stirring blade 405 and the bevel gear 406 to rotate through the connecting shaft 404. When the bevel gear 406 rotates around the rotating shaft 402, it rotates by meshing with the bevel gear 407. Therefore, the stirring blade 405 can tumble when it rotates around the rotating shaft 402.

[0032] A support frame 5 is provided on the outside of the protective cylinder 2. Three support frames 5 are arranged in a ring around the protective cylinder 2. A straight slide rail 6 is provided on the outside of the protective cylinder 2. A sliding ring 10 is slidably mounted on the straight slide rail 6. A connecting frame 7 is provided on the outside of the sliding ring 10. An insertion rod 8 is slidably mounted on the connecting frame 7. A spring 9 is provided on the outside of the insertion rod 8. There are two insertion holes on the straight slide rail 6. Pulling the insertion rod 8 out of the insertion hole can control the sliding ring 10 to slide on the straight slide rail 6. When the insertion rod 8 is aligned with the lower insertion hole and inserted, the sliding ring 10 seals the protective cylinder 2. When the insertion rod 8 is aligned with the upper insertion hole and inserted, the sliding ring 10 can be opened, thereby allowing the treated paint to be poured out.

[0033] Example 2

[0034] like Figures 1-2As shown, this utility model proposes a water-based paint pretreatment device. Compared with Embodiment 1, this embodiment details the structure of the impurity removal mechanism.

[0035] The impurity removal mechanism includes a cylinder 301, a lifting frame 302, a water suction pipe 304, and a water pump 305. The water pump 305 is located at the top of the treatment cylinder 1. Multiple water suction pipes 304 are arranged in a ring around the outside of the water pump 305. A water outlet pipe 306 is located at the bottom of the water pump 305. The lifting frame 302 is located at the bottom of the impurity removal ring 303. The outer side of the lifting frame 302 is slidably connected to the treatment cylinder 1, and the connection is sealed to prevent paint leakage from the treatment cylinder 1 during sliding. The cylinder 301 is located at the bottom of the lifting frame 302. Starting the cylinder 301 and the water pump 305... The cylinder 301 drives the lifting frame 302 to move back and forth, and the lifting frame 302 drives the impurity removal ring 303 to move. When the impurity removal ring 303 moves to the top, the bottom of the impurity removal ring 303 is located at the top of the protective cylinder 2, so that the impurities in the paint slide off the device along the inclined surface of the impurity removal ring 303. When the cylinder 301 drives the impurity removal ring 303 to return, due to the filter holes on the impurity removal ring 303, the impurity removal ring 303 can move smoothly to the bottom of the protective cylinder 2. The water pump 305 pumps the water at the bottom of the impurity removal ring 303 back into the processing cylinder 1 for processing through the water pumping pipe 304, so as to thoroughly clean the paint.

[0036] In summary, when using this utility model, the control sliding ring 10 seals the protective cylinder 2, then the paint is poured into the treatment cylinder 1. The motor 401 and cylinder 301 are started. The motor 401 drives the rotating shaft 402 to rotate, which in turn drives the connecting ring 403 to rotate. The connecting ring 403, through the connecting shaft 404, drives the stirring blade 405 and the first bevel gear 406 to rotate. When the first bevel gear 406 rotates around the first rotating shaft 402, it rotates on its own axis through the meshing of the second bevel gear 407. Therefore, the stirring blade 405 can tumble while rotating around the rotating shaft 402. Simultaneously, the cylinder 301 moves the lifting frame 302 back and forth. 2. The impurity removal ring 303 is moved. When the impurity removal ring 303 moves to the top, the impurities in the paint slide off the device along the inclined surface of the impurity removal ring 303. Then, when the cylinder 301 drives the impurity removal ring 303 to return, the water pump 305 pumps the water at the bottom of the impurity removal ring 303 back into the processing cylinder 1 through the water pumping pipe 304 for processing, thereby thoroughly cleaning the paint. After all the paint is processed, the insert rod 8 is pulled out of the insertion hole to control the sliding ring 10 to slide on the straight slide rail 6. After moving to the top of the straight slide rail 6, the insert rod 8 is released. Under the action of the spring 9, the insert rod 8 is aligned with the upper insertion hole and inserted, thereby opening the sliding ring 10 and pouring out the processed paint.

[0037] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
