Description

Technical Field

[0001] The invention belongs to the technical field of bottle blowing machine mold cleaning, and particularly relates to a bottle blowing machine mold cleaning device and a use method thereof. Background Art

[0002] A bottle blowing machine is a device that uses a blow molding process to make bottles from molten plastic granules or preforms. A bottle blowing machine mold is a type of mold that assists in bottle molding. It is usually composed of two templates. When the two templates are combined, a cavity for bottle molding is formed in the middle. The cavity is used to limit the plastic granules or preforms to form the bottle.

[0003] After the blow molding machine mold has been used for a period of time, impurities such as oil, dust, and residual plastic will exist on the side walls of the mold cavity, and the presence of these impurities will affect the molding quality of the bottle. In order to ensure the processing quality of the blow molding machine mold, it is usually necessary to use a blow molding machine mold cleaning device to clean the blow molding machine mold regularly.

[0004] At present, the common blowing machine mold cleaning device mainly adopts immersion cleaning or spray cleaning to clean the mold. No matter immersion cleaning or spray cleaning, the blowing machine mold is cleaned in one step. This cleaning method not only consumes a large amount of cleaning liquid, but also the impurities remaining in the cleaning liquid will be adsorbed again in the blowing machine mold cavity, so that the cleaning effect of the blowing machine mold is poor and the cleaning cycle is long.

[0005] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art.

[0014] In one or more embodiments of the present invention, the rotary airflow dust removal assembly includes a dust cleaning fixing plate, which is arranged in the airflow dust removal chamber. The dust cleaning fixing plate serves as an assembly limit for multiple groups of dust cleaning rollers. At the same time, the dust cleaning fixing plate provides assembly and operation space for the dust cleaning drive gear and the dust cleaning transmission gear. A pair of first telescopic rods are fixedly connected between the dust cleaning fixing plate and the box shell. The dust cleaning fixing plate is provided with an adjustable support and fixation by a pair of first telescopic rods.

[0016] In one or more embodiments of the present invention, an air guide plate is arranged above the dust cleaning fixed plate, and the air guide plate is in communication with multiple groups of dust cleaning rollers. Gas is conducted to multiple groups of dust cleaning rollers through the air guide plate. An air delivery pipe is fixedly connected above the air guide plate. The air delivery pipe serves to connect the air guide plate and the bellows, so that the compressed air in the bellows is delivered to the air guide plate along the air delivery pipe. One end of the air delivery pipe located outside the box shell is fixedly connected to a bellows. The gas output by multiple groups of compression fans is temporarily stored and compressed by the bellows. Multiple groups of evenly distributed compression fans are fixedly connected above the bellows. The operation of multiple groups of compression fans is controlled to allow outside air to enter the bellows.

[0017] In one or more embodiments of the present invention, both sides of the bellows are fixedly connected with side exhaust pipes. The side exhaust pipes play the role of connecting the bellows and the dust-cleaning limit plate, so as to facilitate the extraction of compressed air in the bellows. A pair of side exhaust pipes are fixedly connected with dust-cleaning limit plates at one end located in the airflow dust removal chamber, and the dust-cleaning limit plate is tilted and arranged close to the box seat on the side close to the dust-cleaning roller. It is convenient to blow air between the mold cavities to be cleaned through the tilted dust-cleaning limit plate, which improves the effect of floating impurities between the mold cavities to be cleaned falling into the impurity storage chamber. A liquid guide plate is tiltedly installed in the box seat, and the liquid guide plate is arranged directly below the mixed cleaning chamber and the drying and drying chamber.

The cleaning drive motor plays the role of providing power, and the cleaning transmission gear is rotationally driven by controlling the operation of the cleaning drive motor, thereby facilitating synchronous driving of the steam conveying roller and the pair of liquid conveying rollers.

[0019] In one or more embodiments of the present invention, the steam conveying roller and the pair of liquid conveying rollers are both hollow. By setting the steam conveying roller and the pair of liquid conveying rollers hollow, it is convenient to guide and convey the cleaning liquid and hot steam. A guide plate is arranged above the cleaning fixed plate. The guide plate is respectively connected to the steam conveying roller and the pair of liquid conveying rollers, and the steam conveying roller and the pair of liquid conveying rollers are assembled and limited and the liquid and gas conduction is controlled through the guide plate. A steam conveying pipe is fixedly connected above the guide plate, and the steam conveying pipe is connected to the steam conveying roller. It is convenient to convey hot steam into the steam conveying roller through the steam conveying pipe. Liquid conveying pipes are arranged on both sides of the steam conveying pipe, and a pair of the liquid conveying pipes are respectively connected to a pair of liquid conveying rollers. Clean liquid is conveyed to the liquid conveying roller through the liquid conveying pipe.

[0020] A method for using a bottle blowing machine mold cleaning device comprises the following steps:

[0021] S1. According to the size of the mold to be cleaned, the positions of the multiple sets of limit blocks on the conveying rollers are adjusted, and a pair of molds to be cleaned are placed between the multiple sets of limit blocks. Subsequently, the conveying rollers are driven to rotate by controlling the operation of the conveying motor. The multiple sets of conveying rollers rotate synchronously under the cooperation of the synchronous gears and the synchronous toothed belts, and the molds to be cleaned are supported and moved by the rotation of the multiple sets of conveying rollers;

[0022] S2. The mold to be cleaned is moved into the airflow dust removal chamber under the action of multiple groups of conveying rollers. Subsequently, the outside air can be compressed and enter the bellows by controlling the operation of the compression fan, and then transported to multiple dust cleaning rollers along the conveying air pipe and the air guide plate. Multiple groups of dust cleaning air nozzles on the outer sides of the dust cleaning rollers spray compressed air into the cavity of the mold to be cleaned, thereby preliminarily cleaning the impurities in the cavity of the mold to be cleaned;

[0023] S3. At the same time, the dust cleaning transmission gear can be driven to rotate by controlling the operation of the rotary motor, and multiple sets of dust cleaning rollers rotate under the meshing action of the dust cleaning driving gear and the dust cleaning transmission gear. The rotation of the multiple sets of dust cleaning rollers can be used to perform a rotary dust blowing process on the mold cavity to be cleaned;

[0024] S4. In addition, the compressed air in the bellows can be blown along the side exhaust pipe and the dust-cleaning limit plate to the space between the mold cavities to be cleaned, so that the impurities blown off between the molds to be cleaned can fall into the impurity storage cavity under the action of the airflow of the dust-cleaning limit plate and its own gravity for collection, and the cleaning liquid in the impurity storage cavity flows into the liquid storage reflux cavity after being filtered by the filter plate;

[0025] S5. After the airflow dust removal, the mold to be cleaned can be continuously moved under the action of multiple groups of conveying rollers. When the mold to be cleaned moves into the mixed cleaning chamber, hot steam can be conveyed into the steam conveying roller through the steam conveying pipe, and cleaning liquid can be conveyed into the liquid conveying roller through the liquid conveying pipe, and hot steam and cleaning liquid can be sprayed into the cavity of the mold to be cleaned through multiple groups of nozzles, so that the hot steam and the cleaning liquid can be mixed and cleaned for the mold to be cleaned;

[0026] S6. In addition, the cleaning drive motor can be controlled in the same way to drive the cleaning transmission gear to rotate. The steam delivery roller and the pair of liquid delivery rollers can rotate under the meshing action of the cleaning transmission gear and the cleaning drive gear. The mold cavity to be cleaned can be fully cleaned by the rotation of the steam delivery roller and the pair of liquid delivery rollers. The cleaning liquid dripping from the cleaning can be guided along the liquid guide plate.

[0027] S7. The mold to be cleaned after cleaning will continue to move under the action of multiple sets of conveying rollers. When the mold to be cleaned moves into the drying chamber, the mold cavity to be cleaned is wiped and airflow dried by the operation of the wiping and drying mechanism. The dried mold can be led out under the action of multiple sets of conveying rollers, thereby completing the cleaning process of the blow molding machine mold.

[0028] Compared with the prior art, the present invention can perform multiple cleanings on the blow molding machine mold by performing step-by-step cleaning on the blow molding machine mold, thereby significantly improving the cleaning effect of the blow molding machine mold;

[0029] By adopting the cleaning method of combining hot steam with cleaning liquid, the consumption of cleaning liquid for the blow molding machine mold is greatly reduced, the cleaning cycle of the blow molding machine mold is shortened, and the convenience of cleaning the blow molding machine mold is improved.

[0096] A method for using a bottle blowing machine mold cleaning device comprises the following steps:

[0097] According to the size of the mold to be cleaned, the positions of the multiple sets of limit blocks 208 on the conveying roller 202 are adjusted, and a pair of molds to be cleaned are placed between the multiple sets of limit blocks 208. Subsequently, the conveying roller 202 is driven to rotate by controlling the operation of the conveying motor 211. The multiple sets of conveying rollers 202 rotate synchronously under the cooperation of the synchronous gear 209 and the synchronous toothed belt 210, and the mold to be cleaned is supported and moved by the rotation of the multiple sets of conveying rollers 202.

[0098] The mold to be cleaned is moved into the airflow dust removal chamber 205 under the action of multiple groups of conveying rollers 202. Subsequently, the outside air can be compressed and enter the bellows 222 by controlling the operation of the compression fan 223, and is conveyed to the multiple dust cleaning rollers 215 along the conveying air pipe 221 and the air guide plate 220. The multiple groups of dust cleaning air nozzles 216 on the outside of the dust cleaning rollers 215 spray compressed air into the cavity of the mold to be cleaned, thereby preliminarily cleaning the impurities in the cavity of the mold to be cleaned.

[0099] At the same time, the dust cleaning transmission gear 218 can be driven to rotate by controlling the operation of the rotary motor 219, and multiple groups of dust cleaning rollers 215 rotate under the meshing action of the dust cleaning drive gear 217 and the dust cleaning transmission gear 218. The rotation of multiple groups of dust cleaning rollers 215 can perform a rotary dust blowing treatment on the mold cavity to be cleaned.

[0100] In addition, the compressed air in the bellows 222 can be blown along the side exhaust pipe 224 and the dust cleaning limit plate 225 toward the space between a pair of mold cavities to be cleaned, so that the impurities blown off between the pair of molds to be cleaned can fall into the impurity storage chamber 228 for collection under the action of the airflow of the dust cleaning limit plate 225 and its own gravity, and the cleaning liquid in the impurity storage chamber 228 is filtered by the filter plate 227 and then flows into the liquid storage reflux chamber 229.

[0101] The mold to be cleaned after air flow dust removal can continue to move under the action of multiple groups of conveying rollers 202. When the mold to be cleaned moves into the mixed cleaning chamber 206, hot steam can be conveyed into the steam conveying roller 302 through the steam conveying pipe 310, and cleaning liquid can be conveyed into the liquid conveying roller 303 through the liquid conveying pipe 311, and hot steam and cleaning liquid can be sprayed into the cavity of the mold to be cleaned through multiple groups of nozzles 304, so that the hot steam and cleaning liquid can be mixed and cleaned for the mold to be cleaned.

The steam delivery roller 302 and a pair of liquid delivery rollers 303 will rotate under the meshing action of the cleaning transmission gear 307 and the cleaning drive gear 306. The mold cavity to be cleaned can be fully cleaned by the rotation of the steam delivery roller 302 and a pair of liquid delivery rollers 303, and the dripping cleaning liquid can be guided along the liquid guide plate 226.

[0103] The mold to be cleaned after cleaning will continue to move under the action of multiple sets of conveying rollers 202. When the mold to be cleaned moves into the drying chamber 207, the operation of the drying motor 406 is controlled to make the multiple sets of drying rollers 402 rotate under the meshing action of the drying drive gear 404 and the drying transmission gear 405, and the mold after cleaning is wiped and cleaned by the rotation of the multiple sets of drying rollers 402.

[0104] At the same time, part of the compressed air in the bellows 222 can be transported to the heat exchange coil 409 along the exhaust pipe 410, and after heating, it is transported to the multiple groups of drying rollers 402 along the hot air guide pipe 408 and the drying exhaust plate 407, and discharged along multiple air outlets, thereby assisting in drying the cleaned mold.
