The utility model discloses a blow molding machine easy to clean, which belongs to the technical field of blow molding machines and comprises a blow molding machine body and a mold body, a mounting plate is arranged between the mold body and the blow molding machine body, mounting racks are symmetrically arranged on two sides of the mounting plate, cleaning mechanisms are connected onto the mounting racks, and the cleaning mechanisms are connected with the blow molding machine body. The cleaning mechanism comprises a rolling brush, two first connecting rods, a second connecting rod and a second bevel gear assembly, and the second bevel gear assembly comprises two meshed second bevel gears; through cooperative use of all the devices, a mold cavity of the mold body is cleaned, an arranged spring pushes a rolling brush to be close to the mold cavity of the mold body through the reset effect, then a second motor is started, and the rolling brush is driven to rotate under the effect of a rotating rod and a first bevel gear assembly, so that the mold cavity of the mold body is cleaned; dust or impurities are prevented from being attached to the surface of the cavity in the production process, and the forming quality of plastic products is not affected.

This invention discloses a nitrogen supply system and its control method, as well as glass manufacturing equipment, relating to the field of glass manufacturing technology. The nitrogen supply system includes a main gas supply module and an emergency gas supply module. The emergency gas supply module includes a gas supply regulating device, which comprises a first regulating valve and a second regulating valve connected in parallel. The first regulating valve is activated when the gas supply pressure of the main gas supply module is lower than a critical threshold, so as to replenish the gas flow of the production line module to a safe threshold. The second regulating valve is activated when the gas flow of the production line module increases to the safe threshold, so as to replenish and maintain the gas flow of the production line module to a rated threshold. The response speed of the first regulating valve is superior to that of the second regulating valve. The technical solution provided by this invention can quickly and stably provide a backup gas source to ensure the stability of the nitrogen flow.
