[0002] Bottle blowing machines or blow molding machines are common equipment commonly used in the production of glass bottles and plastic bottles. Taking bottle blowing machines as an example, bottle blowing machines can be divided into two categories according to their working principles, namely, one-step bottle blowing machines that use one-time blowing to complete the glass bottle processing and two-step bottle blowing machines that use two-time blowing to complete the glass bottle processing. Both of these bottle blowing machines include a clamping device, which uses the clamping cavity on the clamping device to limit the shape of the glass bottle after the preform is formed.

[0003] When processing glass bottles, after shaping them, they need to be quickly cooled to room temperature. The existing method usually places the glass bottles at room temperature to allow them to cool naturally. However, natural cooling takes a long time, which cannot be well met in the production of large quantities of glass bottles and is easy to waste a lot of time, thereby causing the overall rhythm of the production line to be reduced, at least affecting the production efficiency to a certain extent. In view of this, a module cooling device for bottle blank blow molding is proposed to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-2 In this embodiment, a mold cooling device for blow molding of preforms includes a transport frame 1, a plurality of rollers 5 are rotatably mounted inside the transport frame 1, one of the rollers 5 is driven to rotate by an external motor, thereby driving a conveyor belt 4 outside the roller 5 to transmit, a conveyor belt 4 is transmitted outside the roller 5, a fixing component 3 is provided on the conveyor belt 4, a protective cover 6 is fixed on the upper end surface of the transport frame 1, openings for bottles to enter and exit are opened at the left and right ends of the protective cover 6, and a cooling mechanism 2 is provided inside the protective cover 6;

[0021] The cooling mechanism 2 includes a first cooling fan 201, an air suction hood 204 and a suction fan 202. Multiple first cooling fans 201 are fixed to the front and rear side walls of the inner cavity of the protective cover 6. The air suction hood 204 is fixed to the top wall of the inner cavity of the protective cover 6. The suction fan 202 is fixed to the upper end of the protective cover 6. A transmission pipe 203 is connected between the output end of the suction fan 202 and the air suction hood 204.

[0022] The device starts the first cooling fan 201, which blows air onto the preform to cool it preliminarily, and then starts the fan, so that the hot air generated by the preform is sucked into the suction hood 204, transported to the transmission pipe 203, and discharged by the suction fan 202.

[0023] The cooling mechanism 2 comprises a water tank 206, a water collecting box 210 and a water pump 208. The water tank 206 and the water pump 208 are fixed on the protective cover 6 in sequence. The water inlet end of the water pump 208 is connected to one side of the water tank 206, and the water outlet end of the water pump 208 is connected to the water inlet pipe 209. The water collecting boxes 210 are fixed to the front and rear side walls of the inner cavity of the protective cover 6. A plurality of atomizing nozzles 211 equidistantly distributed are fixed to one side of the water collecting box 210. A refrigerator 205 is arranged in the water tank 206. By starting the water pump 208, the water pump 208 transports water to the water inlet pipe 209 and the water collecting box 210, and then the atomizing nozzle 211 sprays water to cool the preform again, and the liquid in the water tank 206 is cooled by the refrigerator 205.

[0024] Meanwhile, the cooling mechanism 2 comprises a second cooling fan 207. A plurality of second cooling fans 207 are fixed to the front and rear side walls of the inner cavity of the protective cover 6. The second cooling fans 207 are started to dry the water droplets on the preform, thereby facilitating the subsequent production process of the preform.

[0025] In addition, two waterproof curtains are fixed on the top of the inner cavity of the protective cover 6. The two waterproof curtains are respectively located on both sides of the water collecting box 210 to block the water mist from spreading to the working places of the first cooling fan 201 and the second cooling fan 207.

[0026] See also Figure 1 and Figure 3 The fixing assembly 3 in this embodiment includes a fixing cylinder 301, a plurality of equally spaced conveying cylinders are fixed on the conveyor belt 4, an air bag 303 is fixed in the conveying cylinder, a push rod 302 is fixed at the upper end of the air bag 303, an exhaust pipe 304 is fixed on one side of the air bag 303, and the upper end of the push rod 302 passes through the fixing cylinder 301 and is slidably connected to the fixing cylinder 301

[0027] When the device inserts the bottle blank into the fixed cylinder 301 with the bottle mouth facing downward through the external mechanical gripper, the push rod 302 then moves downward, the push rod 302 squeezes the air bag 303, and the gas in the air bag 303 is discharged through the exhaust hole, thereby playing a certain buffering role on the bottle blank.

[0028] The working principle of the above embodiment is:

[0029] When the preform needs to be cooled, an external mechanical gripper inserts the preform into the fixing cylinder 301 with the bottle mouth facing downward, and then the push rod 302 moves downward to squeeze the airbag 303, and the gas in the airbag 303 is discharged through the exhaust hole to cushion the preform.

[0030] Then, the first cooling fan 201 is started to blow air onto the preform to preliminarily cool it. Then, the fan is started to suck the hot air generated by the preform into the suction hood 204, and then transport it to the transmission pipe 203, and then discharged by the suction fan 202.

[0031] When the preform moves to the water collecting box 210, the liquid in the water tank 206 is cooled by the refrigerator 205, and the water is transported to the water inlet pipe 209 and the water collecting box 210 by the water pump 208, and then the water is sprayed onto the preform by the atomizing nozzle 211 to cool the preform again.

[0032] When the preform moves to the second cooling fan 207, the second cooling fan 207 is started to dry the water droplets on the preform, so that the preform can be easily processed in subsequent production processes.
