[0032] In the glass bottle production process, the forming link needs to use oiling stick to oil the mold regularly to prevent glass bottles from sticking to the inside of the mold, however, due to the direct contact of the oiling stick with high-temperature forming, the flammable nature of the oil liquid causes the risk of being ignited, and currently, fire sand is generally used to extinguish the oiling stick fire, but this method has a significant technical defect, specifically, during the extinguishing process, the oil liquid on the oiling stick will inevitably flow into the fire sand, and with the repeated extinguishing operation, the amount of oil liquid accumulated in the fire sand gradually increases, which not only reduces the effectiveness of the fire sand, but more seriously, greatly increases the risk of secondary ignition.

[0033] For example, on a production line producing 500,000 glass bottles per day, each forming machine needs to perform 3-5 oiling operations per hour, assuming that 10% of the oiling operations will cause the oiling stick to be ignited, then 60-100 fire extinguishing operations may be required per day, considering that about 5-10 milliliters of oil liquid will seep into the fire sand during each extinguishing process, after a week of production cycle, the amount of oil liquid accumulated in the fire sand may reach 2-7 liters, in this case, the fire sand has become highly flammable, and its fire extinguishing effect is significantly reduced. Further, due to the uneven distribution of oil liquid in the fire sand, the oil liquid concentration in some areas may be higher, and these areas become potential fire sources, which are easily ignited by high-temperature forming or sparks.

[0035] Through the technical scheme, when the oiling stick is ignited, the operator inserts the oiling stick into the fire extinguishing sand in the sand storage cavity 3 through the fire extinguishing opening 4, so that the fire of the oiling stick is extinguished, and part of the oil liquid of the oiling stick will seep into the fire extinguishing sand at this time; at this time, the sand pushing motor 5 drives the rotating shaft 6 and the sand pushing plate 7 to rotate, the sand pushing plate 7 pushes the fire extinguishing sand containing the oil liquid to the lower side of the oil absorbing plugboard 12, and the oil absorbing paper 11 absorbs the oil liquid seeping into the fire extinguishing sand, thereby preventing the oil liquid from accumulating in the fire extinguishing sand, ensuring that the fire extinguishing sand always maintains a relatively low oil liquid content, and greatly reducing the risk of secondary ignition.

[0036] In addition, in order to avoid the fire of the oiling stick igniting the oil absorbing paper 11, it is necessary to ensure that the fire of the oiling stick is completely extinguished and separated from the sand storage cavity 3 before the sand pushing plate 7 rotates, so as to prevent sparks from contacting the oil absorbing paper 11.
