Description

Technical Field

[0001] The invention relates to the technical field of tire mold cleaning, in particular to a tire mold laser cleaning device with multiple cleaning heads. Background Art

[0002] The tire mold is composed of side panels and tread blocks. Tread blocks with different patterns can leave different patterns on the tire surface when the tire embryo is vulcanized to meet the use requirements of different road conditions and climatic conditions. When the tire is vulcanized, some release agents, rubber materials and other residues will remain on the mold surface. As the number of times the mold is used increases, the residues on the mold surface accumulate more and more. If it is not cleaned in time, it will affect the quality and appearance of the tire. Compared with traditional cleaning methods, laser cleaning of tire molds has the advantages of not damaging the mold, no consumables, green and environmental protection, low cleaning cost, and can effectively maintain mold accuracy, extend mold life, and reduce labor intensity. Mold laser cleaning equipment has become the preferred cleaning equipment for many tire manufacturers at home and abroad.

[0003] In order to clean all parts of the mold surface pattern, the general laser cleaning equipment is equipped with a cleaning head, which successively scans the mold pattern ribs from four different directions, namely the front, back, left and right, to clean the residues on the mold surface. The same pattern needs to be irradiated four times to be completely cleaned. This cleaning method is time-consuming, and it takes an average of 60 to 80 minutes to clean a mold. For companies with an annual production capacity of 10 million tires, the number of molds that need to be cleaned every day is generally more than 60 pairs. The maximum number of molds that can be cleaned per day by a single cleaning head laser cleaning equipment does not exceed 24 pairs. In order to ensure the normal production, tire companies have to invest heavily in purchasing multiple laser cleaning equipment or use traditional cleaning processes that will damage the mold and pollute the environment.

In order to make the energy threshold of the cleaning spot emitted by the laser cleaning head body 504 between the gasification value of the sulfide and the damage value of the tire mold body 4, the laser power emitted by the laser cleaning head body 504 can be adjusted to a power of 200-2000W. The single pulse energy is 20-100mj, the frequency is 2-4000kHz, and the pulse width is between 20-150ns.

Then the optical fiber transmits the laser emitted by the pulse laser 701 to the optical lens group, and then emits it. Among them, the optical lens group is used to adjust the cleaning light spot emitted by the laser cleaning head body 504. Finally, the residue on the surface of the tire mold is cleaned by the cleaning light spot.
