Technical Field

[0001] The utility model relates to the technical field of coating processing, and more particularly to a mixing kettle with a scraping structure for coating processing. Background Art

[0002] Mixing kettles are essential equipment in the paint production process. However, in traditional mixing kettles, materials easily adhere to the kettle walls, affecting paint quality and production efficiency. Existing scraping mechanisms in mixing kettles are generally used to remove residual paint from the kettle walls during cleaning, rather than for mixing during processing. This results in uneven mixing during paint processing.

[0003] Chinese patent publication number CN219272807U discloses a water-based paint mixing kettle. This utility model drives a combing scraper to move up and down through the cooperation of a rotating screw and a wire sleeve. The combing scraper that moves up and down can comb and stir the water-based paint inside the mixing kettle up and down. At the same time, the combing scraper that moves up and down can scrape and clean the inside of the mixing kettle. Although this patent uses a combing scraper to scrape the material while stirring, its structure is complex and the stirring range of the stirring rod is small. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a mixing kettle for coating processing with a scraping structure to solve the above deficiencies.

[0005] In order to achieve the above-mentioned purpose, the technical solution provided by the present utility model is:

[0006] The utility model discloses a mixing kettle for paint processing with a scraping structure, comprising a mixing kettle body, a driving motor being arranged on the top of the mixing kettle body, an output end of the driving motor being fixedly connected to a stirring shaft, both ends of the stirring shaft being movably connected to the mixing kettle body through bearings, a scraping component being sleeved on the stirring shaft and movable up and down, and the scraping component scrapes off the material sticking to the inner wall of the mixing kettle body to prevent uneven stirring of the material and facilitates cleaning the inner wall of the mixing kettle body.

[0007] Preferably, the stirring shaft is provided with a stirring blade, and the stirring blade is arranged in a pyramid structure.

[0008] Preferably, an annular groove is provided on the stirring shaft, and the annular groove is arranged obliquely. The obliquely arranged annular groove has a height difference between a high position and a low position, and is used to control the movement of the scraping component.

[0009] Preferably, the scraping assembly includes a guide rod and a scraping ring, the upper and lower ends of the guide rod are fixedly connected to the upper and lower bottom surfaces of the mixing kettle body respectively, and the guide rod limits the scraping ring so that the scraping ring moves up and down along the guide rod.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings.

[0021] Combine Figures 1-4 The utility model is a mixing kettle for paint processing with a scraping structure. A stirring shaft 2 is arranged inside the mixing kettle body 1. The stirring shaft 2 is driven to rotate by a driving motor 11 connected to the top of the mixing kettle body 1. Both ends of the stirring shaft 2 are movably connected to the mixing kettle body 1 through bearings. A scraping component 3 that can move up and down is sleeved on the stirring shaft 2. The scraping component 3 scrapes the material sticking to the inner wall of the mixing kettle body 1 to prevent uneven stirring of the material and facilitates cleaning the inner wall of the mixing kettle body 1.

[0022] In order to improve the stirring effect, at least two layers of stirring blades 21 are provided on the stirring shaft 2. The stirring blades 21 are arranged in a pyramid structure. The diameter of the stirring blade 21 at one end close to the stirring shaft 2 is larger than the other end, thereby enhancing the stability of the stirring blade 21. The two sides of the stirring blade 21 are inclined structures, which can increase the shear force on the material and accelerate the mixing of the material. At the same time, in order to avoid limited movement of the stirring blade 21 and to meet the movement needs of the scraping component 3, the end of the stirring blade 21 is a certain distance away from the inner wall of the mixing kettle body 1.

[0023] In this embodiment, the scraping assembly 3 includes a guide rod 31 and a scraping ring 32. The upper and lower ends of the guide rod 31 are fixedly connected to the upper and lower bottom surfaces of the mixing kettle body 1 respectively. The scraping ring 32 includes an inner ring 321, an outer ring 322 and a connecting rod 323 connecting the inner ring 321 and the outer ring 322. The outer ring 322 is provided with a sleeve hole 3221 that matches the guide rod 31. Under the restriction of the sleeve hole 3221, the scraping ring 32 can only move up and down along the guide rod 31. The guide rod 31 is arranged at a position between the end of the stirring blade 21 and the inner wall of the mixing kettle body 1.

[0024] In this embodiment, the stirring blade 21 divides the stirring shaft 2 into at least three sections, and each section of the stirring shaft 2 is provided with an inclined annular groove 22. The stirring shaft 2 provided with the annular groove 22 is sleeved with the inner ring 321, and the inner ring 321 is provided with a sliding ball 3211 matching the annular groove 22. When the stirring shaft 2 rotates, the annular groove 22 rotates synchronously and acts on the sliding ball 3211. Due to the limitation of the guide rod 31, the sliding ball 3211 cannot follow the rotation, and then moves up and down in the annular groove 22 to meet the rotation of the stirring shaft 2. Accordingly, when the stirring shaft 2 rotates, the scraping ring 32 moves up and down, and the outer ring 322 scrapes the material on the inner wall of the mixing kettle body 1. At the same time, the scraping ring 32 moving up and down can extrude the material in the mixing kettle body 1, further improving the mixing degree of the material.

[0025] In order to further improve the mixing effect, in this embodiment, the annular grooves 22 on different sections of the stirring shaft 2 are set in different directions, so that adjacent scraping rings 32 move toward or in opposite directions at the same time, and can squeeze the materials on different sections and layers in different directions, so as to achieve better mixing effect. The thickness of the outer ring 322 is set to be higher than that of the inner ring 321. At the location where the stirring blade 21 is set, the outer ring 322 can also achieve scraping to avoid dead corners for scraping. The upper and lower ends of the outer ring 322 are both conical structures to reduce the resistance of scraping materials.

[0026] Working process: During the coating processing, the coating to be mixed is put into the mixing kettle body 1, and the drive motor 11 is turned on. The stirring shaft 2 drives the stirring blade 21 to rotate to mix the materials in the mixing kettle body 1. During the process, the inner ring 321 drives the outer ring 322 to move up and down along the guide rod 31 through the connecting rod 323. The outer ring 322 scrapes the material on the inner wall of the mixing kettle body 1. The scraped material is mixed with the material of the mixing kettle body 1. The scraping ring 32 moving in the opposite direction squeezes and mixes the materials in the upper and lower sections to further improve the mixing effect.
