Technical Field

[0001] This application relates to the technical field of paint production equipment, and in particular to an automatic stirring device for hot-melt road marking paint. Background Technology

[0002] Traffic markings, as crucial traffic safety facilities, play an irreplaceable role in ensuring safe driving and efficient travel. Quality issues can lead to serious traffic safety hazards, especially in rainy weather and at night. The Ministry of Transport has imposed strict requirements on the quality and performance of paints used for road markings. Hot-melt road marking paints, due to their low cost, fast drying, thick film, and simple application equipment, are currently the most widely used type of road marking paint in my country, accounting for nearly 90% of total usage.

[0003] Hot-melt road marking paint requires heating to approximately 180-220℃ while slowly stirring to ensure even heating. The molten paint is then poured into a standard mold and cooled to room temperature to obtain a standard sample. Since the main components of the paint are synthetic resin, calcium carbonate, titanium dioxide, glass microspheres, coloring pigments, PE wax, fillers, and EVA, the heating process generates toxic gases that pose a certain health hazard.

[0031] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0032] This application discloses an automatic mixing device for hot-melt road marking paint. (Refer to...) Figure 1 and Figure 2 The automatic mixing device for hot-melt road marking paint includes a mixing tank 1, with an electric heating plate 11 installed at the bottom of the mixing tank 1. A stirring rod 12 is rotatably installed inside the mixing tank 1, and a motor 13 is installed on the top of the mixing tank 1. The output end of the motor 13 is fixedly connected to the top end of the stirring rod 12.

[0033] Reference Figure 2 and Figure 3 A feeding groove 21 is provided on the top surface of the mixing tank 1. A control groove 22 is provided on the inner wall of the feeding groove 21. A control plate 2 is slidably mounted on the mixing tank 1 along its circumference through the control groove 22. A limit groove 23 is provided on the inner wall of the control groove 22. A limit block 24 is fixed on the inner arc surface of the control plate 2 near the motor 13. The limit block 24 slides and engages with the mixing tank 1 along its circumference through the limit groove 23. An internal gear ring 25 is rotatably mounted in the control groove 22. The outer arc surface of the control plate 2 away from the motor 13 is fixedly connected to the internal gear ring 25. A connecting groove 26 is provided on the top of the mixing tank 1. A drive rod 27 is rotatably mounted in the connecting groove 26. A gear 28 is fixedly fitted on the outer circumference of the drive rod 27. The gear 28 meshes with the internal gear ring 25. The top end of the drive rod 27 extends out of the top of the mixing tank 1 and is fixed with a handle 271.

[0034] Rotating the handle 271 causes the drive rod 27 to rotate, which in turn drives the gear 28 to rotate. The gear 28 then drives the internal gear ring 25 to rotate, which in turn drives the control plate 2 to rotate, thus facilitating the operator to add materials.

[0035] Reference Figure 2 and Figure 4A vent pipe 3 is provided on the side of the mixing tank 1, and a fan 31 is fixed inside the vent pipe 3. A connecting pipe 32 is fitted around the outer periphery of the vent pipe 3, and the connecting pipe 32 is threadedly connected to the vent pipe 3. A positioning hole 33 is opened on the outer periphery of the vent pipe 3, and a positioning through hole 321 is opened on the outer periphery of the connecting pipe 32. A positioning pin 34 passes through the positioning through hole 321 and can be inserted into the positioning hole 33.

[0036] When the adsorption effect of the activated carbon disc 35 decreases, it needs to be replaced. The operator can first remove the positioning pin 34, then separate the connecting pipe 32 from the gas outlet pipe 3, and the activated carbon disc 35 can be moved from the side of the connecting pipe 32 closer to the gas outlet pipe 3. Then, the new activated carbon disc 35 can be placed from the side of the connecting pipe 32 away from the gas outlet pipe 3.

[0037] Reference Figure 4 A plurality of stacked activated carbon discs 35 are installed inside the connecting pipe 32, with the outer circumferential surface of the activated carbon discs 35 fitting against the inner circumferential surface of the connecting pipe 32. Two symmetrically arranged clearance grooves 36 are formed on the inner circumferential surface of the connecting pipe 32, and a rotating rod 37 is fixed within each clearance groove 36. A baffle 38 is fitted around the outer circumference of the rotating rod 37, and the baffle 38 abuts against the side of the activated carbon discs 35 away from the outlet pipe 3. A torsion spring 371 is fitted around the outer circumference of the rotating rod 37, with one end of the torsion spring 371 fixedly connected to the baffle 38 and the other end fixedly connected to the inner wall of the clearance groove 36, allowing the side of the baffle 38 away from the outlet pipe 3 to fit against the inner wall of the clearance groove 36 away from the outlet pipe 3.

[0038] Under the elastic force of the torsion spring 371, the baffle 38 abuts against the activated carbon disc 35, making it difficult for the activated carbon disc 35 to detach from the connecting pipe 32, while improving the gas output efficiency.

[0039] The implementation principle of the automatic stirring device for hot-melt road marking paint in this application embodiment is as follows: a certain mass of powdered sample is placed into the stirring tank 1, the motor 13 and the electric heating plate 11 are started, the electric heating plate 11 heats the sample, the motor 13 drives the stirring rod 12 to rotate, the stirring rod 12 slowly stirs the sample in the stirring tank 1, the fan 31 discharges the harmful gas generated during the sample stirring process into the connecting pipe 32, the activated carbon disc 35 in the connecting pipe 32 adsorbs the harmful gas, reducing the possibility of the harmful gas causing harm to the human body.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
