Technical Field

[0001] The utility model relates to the technical field of coating processing equipment, in particular to a coating dispersing machine with a scraping device. Background Art

The utility model reduces the workload of the manual operation device, reduces the working difficulty during the operation of the device, improves the effect of fixing mixing drums of different sizes, and also improves the ability to scrape the edges of mixing drums of different sizes.

[0004] Similar paint dispersers need to contact the inner wall of the mixing barrel when scraping, and the scraping parts and the inner wall of the mixing barrel are both made of hard materials, which causes a large amount of friction heat to be generated between the scraping device and the inner wall of the paint barrel. The direct contact between the scraping device and the inner wall of the paint barrel will cause scratches and damage under long-term friction, and during the stirring, mixing or mixing process of the paint, air will be brought into the paint to form bubbles, thereby affecting the quality of the paint.

[0005] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a coating disperser with a scraping device is proposed. Utility Model Content

[0006] The utility model aims to provide a paint disperser with a scraping device. Since the scraping device needs to contact the inner wall of a stirring barrel when scraping, both the scraping device and the inner wall of the stirring barrel are made of hard materials, resulting in large friction heat between the scraping device and the inner wall of the paint barrel. The scraping device directly contacts the inner wall of the paint barrel and causes scratches and damages under the action of friction for a long time. In addition, during the stirring, mixing or mixing process of the paint, air will be brought into the paint to form bubbles, thereby affecting the quality of the paint.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a paint disperser with a scraping device, comprising a workbench, a stirring blade, a scraping structure and an electric heating rod, an electric telescopic column is arranged at the center of the upper end surface of the workbench, a load-bearing plate is arranged on the upper end surface of the electric telescopic column, a motor is arranged on the front side of the upper end surface of the load-bearing plate, a transmission rod is arranged on the front side of the lower end surface of the load-bearing plate, the electric heating rod is arranged at the lower end of the transmission rod, and fixing rings are arranged on the upper and lower ends of the electric heating rod, the stirring blades are respectively arranged on the outer surfaces of two groups of the fixing rings, a connecting rod is arranged between the two groups of the stirring blades, four groups of the connecting rods are arranged, the scraping structures are respectively arranged on the outer sides of the four groups of the connecting rods, electric push rods are arranged on both sides of the upper end surface of the workbench, limiting plates are arranged on the opposite surfaces of the electric push rods, and clamping frames are arranged on the output ends of the two groups of the electric push rods.

[0008] Furthermore, the positions of the motor and the transmission rod correspond to each other in a vertical manner, and the transmission rod is connected to the output end of the motor by passing through the load-bearing plate.

[0009] Furthermore, the two groups of fixing rings are fixed to the lower end of the transmission rod by screws respectively, and each four groups of stirring blades are equidistantly spaced around the outer surface of each group of fixing rings.

[0010] Furthermore, the positions of every two groups of stirring blades correspond to each other in an up-and-down vertical manner, and the ends of the eight groups of stirring blades away from the outer surface of the transmission rod are connected to each other through four groups of connecting rods.

[0011] Furthermore, the scraping structure is made of silicone, and the connecting rod and the scraping structure are in contact with each other.

[0012] Furthermore, an electric heating wire is arranged on the inner surface of the heating rod, and the electric heating wire is spirally wrapped around the inner surface of the heating rod. The shape of the clamping frame is a semicircular structure, and two groups of the clamping frames form a group of circular ring structures.

[0013] Compared with the prior art, the utility model has the following beneficial effects: the scraping structure can ensure that the paint bucket is in close contact with the surface of the dispersion disk during high-speed rotation, and the paint bucket will not be scratched or worn during the movement of the dispersion scraping work, and the damage to the dispersion transmission structure is also avoided. The paint is heated by the heating rod to improve its fluidity, which helps to make it easier to remove bubbles during the dispersion process and reduce the generation of bubbles. The specific contents are as follows:

[0014] A motor, a transmission rod, a fixed ring, a stirring blade, a connecting rod, a scraping structure, a heating rod and an electric heating wire are provided. By providing a silicone scraping structure, it can help avoid damage to the paint bucket and the transmission system. Since silicone has excellent softness and elasticity, it can contact the inner surface of the paint bucket during the scraping process. During the dispersion process, the silicone scraping edge can effectively scrape off the paint residues adhering to the inner surface of the paint bucket. The softness of the silicone scraping edge can effectively alleviate the friction between the inner wall of the paint bucket and the surface of the equipment, reduce the risk of mutual wear and damage, and play a protective role in the paint dispersion process. At the same time, the paint is heated by the heating rod and the electric heating wire, thereby reducing the amount of gas dissolved therein and reducing the generation of bubbles in the paint. Heating can also increase the fluidity of the paint, resulting in a decrease in the overall viscosity of the paint, which helps to make it easier to remove bubbles during the dispersion process.

DETAILED DESCRIPTION

[0020] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0021] like Figures 1 to 4As shown, a paint disperser with a scraping device includes a workbench 1, a stirring blade 7, a scraping structure 9 and an electric heating rod 10. An electric telescopic column 2 is arranged at the center of the upper end surface of the workbench 1. The workbench 1 is used to support components and place paint buckets. The electric telescopic column 2 provides telescopic height adjustment for the dispersing height of the disperser to meet different needs. A load-bearing plate 3 is arranged on the upper end surface of the electric telescopic column 2. The load-bearing plate 3 bears the force of the dispersing work and bears its weight. A motor 4 is arranged on the front side of the upper end surface of the load-bearing plate 3. The motor 4 provides rotational power. A transmission rod 5 is arranged on the front side of the lower end surface of the load-bearing plate 3. The positions of the motor 4 and the transmission rod 5 correspond to each other vertically. The transmission rod 5 is connected by The output ends of the load-bearing plate 3 and the motor 4 are connected to each other, and the transmission rod 5 is rotated by the rotational power output by the motor 4. Electric push rods 12 are arranged on both sides of the upper end surface of the workbench 1. The electric push rods 12 adjust the position of the clamping frame 14 by controlling the telescopic length of the output end. The opposite surface of the electric push rods 12 is provided with a limit plate 13. The limit plate 13 limits the moving range of the output end of the electric push rods 12. The output ends of the two groups of electric push rods 12 are provided with clamping frames 14. The shape of the clamping frames 14 is a semicircular structure. The two groups of clamping frames 14 form a group of circular ring structures. The two groups of clamping frames 14 are in a circular ring structure and are clamped by the driving force of the electric push rods 12 against the outer surface of the paint bucket;

[0022] The electric heating rod 10 is arranged at the lower end of the transmission rod 5. The heating rod 10 serves as a heat transfer medium to conduct heat energy to the workpiece to achieve heating treatment of the workpiece. The inner surface of the heating rod 10 is provided with an electric heating wire 11. The shape of the electric heating wire 11 is spirally wrapped around the inner surface of the heating rod 10. The electric heating wire 11 is wrapped around the heating rod 10 so that the heat energy is evenly transferred to the surface of the heating rod 10. By adjusting the current size and heating time of the electric heating wire 11, the heating temperature and time of the workpiece can be controlled to meet the requirements of heating treatment. Heating will increase the thermal motion of the paint molecules and weaken the interaction between the molecules, thereby reducing the viscosity of the paint. When the viscosity of the paint decreases, the fluidity of the paint will increase, making it easier to remove bubbles. Fixed rings 6 are provided at the upper and lower ends of the electric heating rod 10. The fixed rings 6 provide fixed support points for the stirring blades 7 and the connecting rods 8 to ensure the stability and reliability of the entire stirring structure. The stirring blades 7 are respectively arranged on the outer surfaces of the two groups of fixed rings 6. The stirring blades 7 are used to disperse the paint in the paint bucket. A connecting rod 8 is provided between the two groups of stirring blades 7. Four groups of connecting rods 8 are provided. The connecting rods 8 provide a support function for the scraping structure 9. The two groups of fixed rings 6 are respectively fixed to the lower ends of the transmission rod 5 by screws. Every four groups of stirring blades 7 are equidistantly spaced around the outer surface of each group of fixed rings 6. The positions of every two groups of stirring blades 7 correspond to each other in an up and down vertical manner, and the eight groups of stirring blades 7 are away from one end of the outer surface of the transmission rod 5. They are connected to each other through four groups of connecting rods 8, and two groups of fixed rings 6 are surrounded by four groups of stirring blades 7 to form a stirring structure. The four groups of stirring blades 7 on the surface of one group of fixed rings 6 are connected to the four groups of stirring blades 7 on the surface of the other group of fixed rings 6 through four groups of connecting rods 8, providing support points for scraping structures 9. The scraping structures 9 are respectively arranged on the outside of the four groups of connecting rods 8. The material of the scraping structures 9 is silicone. The connecting rods 8 and the scraping structures 9 are in contact with each other. The end of each group of connecting rods 8 that contacts the inner wall of the paint bucket outward is scraped by the scraping structure 9. The transmission rod 5 is driven to rotate by the motor 4, so that the above structures are rotated to perform dispersed scraping operations in the bucket. The scraping structure 9 made of silicone ensures that the inner surface of the paint bucket and the transmission structure will not be scratched or worn during high-speed rotation.

[0023] In summary, if Figures 1 to 4As shown, the paint dispersing machine with a scraping device has an electric telescopic column 2 on a workbench 1 to support a load-bearing plate 3, and the output ends of two groups of electric push rods 12 correspond to each other, and the limit plate 13 is penetrated to control two groups of clamping frames 14 to clamp the outer surface of the paint bucket, and then the motor 4 drives the transmission rod 5 on the lower end surface of the load-bearing plate 3 to rotate, thereby driving the eight groups of stirring blades 7 in the two groups of fixed rings 6 to rotate, so as to disperse the paint in the paint bucket, and the four groups of stirring blades 7 on the surface of one group of fixed rings 6 are connected with the four groups of stirring blades 7 on the surface of another group of fixed rings 6 through four groups of connecting rods 8, thereby providing an installation point for a scraping structure 9, and the four groups of scraping structures 9 rotate and scrape along the inner wall of the paint bucket through the rotation of the transmission rod 5, and the friction with the paint bucket is alleviated by the soft silicone material;

[0024] During the dispersion operation, the heating rod 10 generates heat on the inner surface through the electric heating wire 11 to achieve the heating effect, and uses the electrical energy to convert into thermal energy to achieve the heating of the material. The heating rod 10 acts as a heat transfer medium to conduct the heat energy to the paint to achieve heating. During the heating process of the paint, the particles in the paint will be activated by the thermal energy, the activity of the particles will increase, the molecular vibration will intensify, and the interaction force between the particles will weaken, resulting in a decrease in the overall viscosity of the paint, which increases the fluidity of the paint and makes it easier to evenly disperse the paint through stirring and dispersing equipment, so that bubbles are easily removed and the generation of bubbles is reduced.
