Description

Technical Field

[0001] This utility model provides a high-efficiency mixing device, belonging to the field of road marking paint technology, and particularly relates to a high-efficiency mixing device for road marking paint. Background Technology

[0002] Road marking paint is a type of paint specifically used to paint traffic markings on road surfaces. It is typically composed of resin, colorant, reflective material, additives, and other components. It features quick drying, wear resistance, weather resistance, and high reflectivity to ensure clear visibility under various weather and lighting conditions, thereby guiding traffic flow and improving road safety.

[0003] Mixing is an indispensable step in the production of road marking paint, ensuring the uniform distribution of components such as resin, pigments, additives, and reflective materials. This directly affects the appearance quality and performance uniformity of the road markings after application. Currently, paint mixing typically employs mechanical stirring, using impeller blades to shear and tumble the mixture. However, traditional stirring methods may result in insufficient mixing and can lead to paint accumulation on the sidewalls of the mixing container, affecting stirring efficiency and paint uniformity. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this application provides a high-efficiency mixing device for road marking paint, which solves the problems of uneven mixing, low efficiency and paint accumulation in traditional mixing methods.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a high-efficiency mixing device for road marking paint, including a mixing tank, wherein the mixing tank is provided with a spiral blade corresponding to itself, and the spiral blade is provided with a plurality of evenly distributed through holes that penetrate itself, the mixing tank is provided with a lifting chamber corresponding to the diameter of the spiral blade, and a return chamber is provided on the side of the lifting chamber away from the spiral blade, and a cleaning block is provided in the return chamber that penetrates one side plate of the lifting chamber and corresponds to the spiral blade.

[0006] Preferably, the upper end of the mixing tank is provided with a drive motor that is connected to the spiral blade, and a mounting base is provided below the drive motor and sleeved on the outside of itself and the mixing tank.

[0007] Preferably, the lifting chamber is fixedly connected to a connecting block that is fixedly connected to the side wall of the mixing tank at one end near the drive motor, and the lifting chamber is provided with a connecting channel that communicates with the return chamber at the other end away from the connecting block, and the mixing tank is provided with an inclined surface placed inside the connecting channel.

[0008] Preferably, a protrusion corresponding to its own shape and closely attached to the inner wall of the lifting chamber is fixedly connected to the side of the spiral blade. The protrusion contacts the cleaning block, and the other side of the cleaning block is closely attached to the side wall of the return chamber, i.e. the inner wall of the mixing tank.

[0009] Preferably, the lifting chamber is provided with a groove that penetrates itself and corresponds to the cleaning block. The contact surfaces between the groove and the cleaning block are smooth contact surfaces, while the contact surfaces between the protrusion and the cleaning block are rough contact surfaces.

[0010] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0011] This invention features a spiral blade with a shape corresponding to the mixing tank. As the spiral blade rotates, it lifts the raw material upwards using its own blade. The raw material then moves up and down through the through-hole, causing the raw material inside the lifting chamber to agitate. The raw material that is lifted to the top of the lifting chamber enters the return chamber and falls back into the lifting chamber through the gaps between the cleaning blocks. It is then lifted again by the spiral blade. When the spiral blade contacts the cleaning block, it uses friction to cause the cleaning block to move erratically. The cleaning block moves irregularly and repeatedly along a certain trajectory, cleaning the side wall of the return chamber and breaking up the raw material.

[0012] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0022] 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.

[0023] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] like Figure 1 and Figure 2 As shown, a high-efficiency mixing device for road marking paint includes a mixing tank 1. The mixing tank 1 has a spiral blade 2 corresponding to itself inside. The upper end of the mixing tank 1 is provided with a drive motor 14 connected to the spiral blade 2. Below the drive motor 14 is a mounting base 15 sleeved on itself and the outside of the mixing tank 1. The spiral blade 2 has a number of evenly distributed through holes 21 that penetrate itself. The mixing tank 1 has a lifting chamber 11 corresponding to the diameter of the spiral blade 2 inside. The side of the lifting chamber 11 away from the spiral blade 2 is provided with a return chamber 12. The return chamber 12 is provided with a cleaning block 13 that penetrates one side plate of the lifting chamber 11 and corresponds to the spiral blade 2.

[0026] In this embodiment, the present invention proposes a high-efficiency mixing device for road marking paint, aiming to solve the problems of incomplete mixing and paint accumulation on the side walls of the mixing tank in the prior art. The device is equipped with a spiral blade 2 adapted to the mixing tank 1. During rotation, the spiral blade 2 uses its blades to lift the raw material, while the raw material descends through the through-hole 21, thus forming a circulating flow of up-and-down stirring within the lifting chamber 11. This process ensures uniform mixing of the raw material and improves mixing efficiency. The mixed raw material is then lifted to the upper part of the lifting chamber 11 and enters the return chamber 12. In the return chamber 12, the raw material is recirculated through the gaps between the cleaning blocks 13 and falls back into the lifting chamber 11, continuing to be lifted by the spiral blade 2. When the spiral blade 2 contacts the cleaning blocks 13, the friction drives the cleaning blocks 13 to perform non-directional motion. The cleaning blocks 13 reciprocate irregularly along a specific trajectory, effectively cleaning the side walls of the return chamber 12 and further dispersing the raw material. This design not only improves mixing efficiency but also ensures the uniformity of the coating, making it suitable for the preparation process of road marking paint.

[0027] like Figure 3 and Figure 4 As shown, a connecting block 16 is fixedly connected to one end near the drive motor 14. This connecting block 16 is fixedly connected to the side wall of the mixing tank 1, ensuring the structural stability between the mixing tank 1 and the lifting chamber 11. A connecting channel is provided at the end of the lifting chamber 11 away from the connecting block 16. This connecting channel communicates with the return chamber 12, allowing the stirred material to flow smoothly between the lifting chamber 11 and the return chamber 12. An inclined surface inside the mixing tank 1 is located within the connecting channel, which helps guide the material to flow along a predetermined path, enhancing the mixing effect. A protrusion is fixedly connected to the side of the spiral blade 2. The shape of the protrusion corresponds to the spiral blade 2 and is tightly attached to the inner wall of the lifting chamber 11. The protrusion design allows the spiral blade 2 to more effectively push the material upward during rotation, enhancing the mixing effect. The protrusion contacts the cleaning block 13, and the other side of the cleaning block 13 is in close contact with the side wall of the return chamber 12, i.e., the inner wall of the mixing tank 1. This design helps the cleaning block 13 to clean the side wall of the return chamber 12 when the spiral blade 2 rotates, preventing paint from accumulating on the side wall. The lifting chamber 11 is provided with grooves that correspond to the cleaning block 13. The contact surfaces of the grooves and the cleaning block 13 are smooth, which helps to reduce friction and allows the cleaning block 13 to move smoothly within the lifting chamber 11. The contact surfaces of the protrusion and the cleaning block 13 are rough, which increases friction and helps the protrusion drive the cleaning block 13 to make non-directional movements during rotation, further enhancing the mixing and cleaning effect.

[0028] When using:

[0029] 1. Installation and preparation phase:

[0030] Place mixing tank 1 on a level working surface to ensure its stability.

[0031] Install the drive motor 14 at the top of the mixing tank 1 and ensure that the motor is properly connected to the spiral blade 2.

[0032] The mounting base 15 is fitted onto the outside of the drive motor 14 and the mixing tank 1 to ensure the stability of the entire equipment.

[0033] Check that all parts are securely installed and ensure there are no loose parts.

[0034] 2. Raw material addition:

[0035] Open the feed port of mixing tank 1 and add the road marking paint raw materials to be mixed into mixing tank 1.

[0036] Ensure that the amount of raw materials added is appropriate; do not overfill to avoid overflow, nor underfill to avoid affecting the mixing effect.

[0037] 3. Start the stirring process:

[0038] Start the drive motor 14, and the spiral blade 2 begins to rotate, driving the raw material to rise and fall, forming a circulating flow.

[0039] Adjust the speed of the drive motor 14 to achieve the ideal stirring speed. The speed should be set according to the characteristics of the raw materials and the stirring requirements.

[0040] 4. Stirring and circulation:

[0041] The through hole 21 on the spiral blade 2 causes the raw material to form an up-and-down agitated circulation inside the lifting chamber 11, ensuring that the raw material is mixed evenly.

[0042] The mixed raw materials are lifted to the top of the lifting chamber 11 and enter the return chamber 12, where they are recycled through the gaps between the cleaning blocks 13.

[0043] 5. Cleaning up and dispersing:

[0044] The protrusions on the spiral blade 2 contact the cleaning block 13, driving the cleaning block 13 to perform non-directional movement, cleaning the side wall of the return chamber 12 while further dispersing the raw materials.

[0045] The grooves on the lifting chamber 11 and the smooth contact surface of the cleaning block 13 reduce friction and ensure that the cleaning block 13 moves smoothly.

[0046] 6. Mixing complete:

[0047] Determine whether mixing is complete based on the preset mixing time or mixing effect.

[0048] After mixing is complete, turn off the drive motor 14 to stop the rotation of the spiral blade 2.

[0049] 7. Raw material removal:

[0050] Open the discharge port of mixing tank 1, take out the well-mixed paint, and use it for road marking construction.

[0051] Ensure that there is no raw material residue on the inner wall of mixing tank 1 and spiral blade 2 for the next use.

[0052] 8. Cleaning and maintenance:

[0053] After use, clean the mixing tank 1, spiral blade 2, lifting chamber 11 and reflux chamber 12 to ensure that there is no paint residue.

[0054] Regularly inspect and maintain the drive motor 14 and other components to ensure long-term stable operation of the equipment.

[0055] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
