Description

Technical Field

[0001] This utility model belongs to the field of blow molding machine mold cleaning technology, specifically relating to a blow molding machine mold cleaning device and its usage method. Background Technology

[0002] A blow molding machine is a device that uses a blow molding process to produce bottles from molten plastic granules or preforms. A blow molding mold is a type of mold that assists in the bottle forming process. It usually consists of two mold plates. After the two mold plates are closed, a cavity for bottle forming is formed in the middle. The bottle is formed by limiting the plastic granules or preforms through the cavity.

[0003] After a period of use, the mold of a blow molding machine will have impurities such as oil, dust, and residual plastic on the side wall of the mold cavity. 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] Currently, common blow molding machine mold cleaning devices mainly use immersion cleaning or spray cleaning to clean the molds. Both immersion cleaning and spray cleaning are one-step cleaning methods for blow molding machine molds. This cleaning method not only consumes a large amount of cleaning fluid, but also allows impurities remaining in the cleaning fluid to be re-adsorbed into the mold cavity of the blow molding machine, resulting in poor cleaning effect and long cleaning cycle.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0007] To achieve the above objectives, the technical solution provided by a specific embodiment of this utility model is as follows:

[0008] A blow molding die cleaning device includes: a housing, a conveying and dust removal mechanism, a mixing and cleaning mechanism, and a wiping and drying mechanism.

[0009] The conveying dust removal mechanism is mounted above the housing base. The conveying dust removal mechanism includes a conveyor frame, which is fixedly mounted above the housing base. Multiple sets of evenly distributed conveying rollers are rotatably mounted inside the conveyor frame. A housing shell is fixedly mounted above the conveyor frame. A pair of partitions are fixedly mounted inside the housing shell. The pair of partitions divide the housing shell into an airflow dust removal chamber, a mixing and cleaning chamber, and a drying chamber. A rotary airflow dust removal assembly is installed inside the airflow dust removal chamber.

[0010] The mixing cleaning mechanism is fixedly mounted on the top of the housing. The mixing cleaning mechanism includes a cleaning fixing plate, which is installed inside the mixing cleaning chamber. A steam conveying roller is rotatably mounted inside the cleaning fixing plate.

The vapor-liquid flow guiding assembly is configured in conjunction with the steam conveying roller and the liquid conveying roller.

[0011] The wiping and drying mechanism is assembled inside the drying chamber and is used to wipe and dry the blow molding die.

[0012] In one or more embodiments of this utility model, multiple sets of limiting blocks are fixedly mounted on the outer sides of the multiple sets of conveying rollers. These limiting blocks restrict the movement of the mold to be cleaned conveyed on the conveying rollers, ensuring the stability of the conveying process. A synchronous gear is fixedly connected to one end of each of the multiple sets of limiting blocks outside the conveyor frame. A synchronous toothed belt is fitted onto the outer side of each of the synchronous gears, and the synchronous toothed belt meshes with the synchronous gears. The meshing of the synchronous toothed belt with the synchronous gears allows for synchronous driving of the conveying rollers.

[0013] In one or more embodiments of this utility model, a conveyor motor is fixedly mounted on one side of the conveyor frame, and the output shaft of the conveyor motor is connected to a single conveyor roller. The conveyor motor provides power, and the single conveyor roller is rotated by controlling the operation of the conveyor motor. Multiple sets of observation windows are fixedly mounted on the outer side of the housing. The cleaning status in the airflow dust removal chamber, the mixing and cleaning chamber, and the drying chamber can be observed and judged through the multiple sets of observation windows.

[0014] In one or more embodiments of this utility model, the rotary airflow dust removal assembly includes a dust removal fixing plate disposed within the airflow dust removal chamber. The dust removal fixing plate serves to limit the assembly of multiple sets of dust removal rollers. Simultaneously, the dust removal fixing plate provides assembly and operating space for the dust removal drive gear and dust removal transmission gear. A pair of first telescopic rods are fixedly connected between the dust removal fixing plate and the housing. These first telescopic rods provide adjustable support and fixation for the dust removal fixing plate. Multiple sets of evenly distributed dust removal rollers are rotatably connected within the dust removal fixing plate. These multiple sets of dust removal rollers serve to assemble, fix, and guide the airflow of the dust removal nozzles. Multiple sets of evenly distributed dust removal nozzles are fixedly mounted on the outer sides of each set of dust removal rollers. This facilitates the ejection of compressed gas through the multiple sets of dust removal nozzles, thereby facilitating the blowing and dust removal of the inner wall of the mold cavity to be cleaned.

[0015] In one or more embodiments of this utility model, each of the multiple sets of dust-cleaning rollers is fixedly connected to a dust-cleaning drive gear on one side within the dust-cleaning fixing plate, and a dust-cleaning transmission gear meshes with each of the multiple dust-cleaning drive gears. The meshing of the dust-cleaning drive gears and the dust-cleaning transmission gears drives the multiple sets of dust-cleaning rollers to rotate, thereby facilitating rotary dust removal of the mold cavity to be cleaned. A rotary motor is fixedly mounted above the dust-cleaning fixing plate, and the output shaft of the rotary motor is connected to a single dust-cleaning roller. The rotary motor provides power, and by controlling the operation of the rotary motor, it drives the dust-cleaning transmission gear to rotate, thus facilitating the rotational drive of the multiple sets of dust-cleaning rollers. All the multiple sets of dust-cleaning rollers are hollow, and the multiple sets of dust-cleaning air nozzles are evenly connected to the dust-cleaning rollers. The dust-cleaning rollers act as an airflow conveyor for compressed gas.

[0016] In one or more embodiments of this utility model, an air guide plate is arranged above the dust removal fixing plate, and the air guide plate is in communication with multiple sets of dust removal rollers. The air guide plate facilitates gas flow through the multiple sets of dust removal rollers. A conveying air pipe is fixedly connected above the air guide plate. The conveying air pipe connects the air guide plate and the air box, facilitating the delivery of compressed air from the air box to the air guide plate. The end of the conveying air pipe located outside the casing is fixedly connected to the air box. The air box temporarily stores and compresses the gas output from the multiple sets of compressed fans. Multiple evenly distributed compressed fans are fixedly connected above the air box. By controlling the operation of the multiple sets of compressed fans, outside air enters the air box.

[0017] In one or more embodiments of this utility model, side exhaust pipes are fixedly connected to both sides of the air box. The side exhaust pipes connect the ventilation box to the dust removal limiting plate, facilitating the exhaust of compressed air from the air box. A dust removal limiting plate is fixedly connected to one end of each pair of side exhaust pipes located within the airflow dust removal chamber. The side of the dust removal limiting plate closest to the dust removal roller is inclined towards the box base. This facilitates air blowing between the cavities of the mold to be cleaned via the inclined dust removal limiting plate, improving the effect of impurities floating between the cavities falling into the impurity storage chamber. A liquid guide plate is inclinedly installed inside the box base, positioned directly below the mixing cleaning chamber and the drying chamber. The liquid guide plate guides the cleaning liquid dripping from the mixing cleaning chamber and the drying chamber. A filter plate is fixedly connected between the liquid guide plate and the box base. The filter plate filters and separates impurities in the cleaning liquid within the impurity storage chamber. The filter plate divides the box base into an impurity storage chamber and a liquid return chamber, with the impurity storage chamber positioned directly below the airflow dust removal chamber.

[0018] In one or more embodiments of this utility model, a pair of second telescopic rods are fixedly connected between the cleaning fixing plate and the housing. These second telescopic rods provide adjustable assembly and fixation for the cleaning fixing plate. A cleaning drive gear is fixedly connected to one end of each of the steam conveying rollers and the pair of liquid conveying rollers located within the cleaning fixing plate, and a cleaning transmission gear meshes between multiple cleaning drive gears. The meshing of the cleaning drive gears and the cleaning transmission gears drives the steam conveying rollers and the pair of liquid conveying rollers to rotate. A cleaning drive motor is fixedly mounted above the cleaning fixing plate, and the output shaft of the cleaning drive motor is connected to a single cleaning transmission gear. The cleaning drive motor provides power, and by controlling its operation, the cleaning transmission gear is rotated, thus facilitating synchronous driving of the steam conveying rollers and the pair of liquid conveying rollers.

[0019] In one or more embodiments of this utility model, both the steam conveying roller and the pair of liquid conveying rollers are hollow. This hollow design facilitates the flow and transport of cleaning liquid and hot steam. A guide plate is provided above the cleaning fixing plate. The guide plate is connected to both the steam conveying roller and the pair of liquid conveying rollers, providing assembly positioning and liquid / gas flow control. A steam conveying pipe is fixedly connected above the guide plate and is connected to the steam conveying roller. This facilitates the delivery of hot steam into the steam conveying roller through the steam conveying pipe. Liquid conveying pipes are evenly distributed on both sides of the steam conveying pipe, and each pair of liquid conveying pipes is connected to the pair of liquid conveying rollers. Cleaning liquid is delivered to the liquid conveying rollers through the liquid conveying pipes.

[0020] A method of using a blow molding die cleaning device includes the following steps:

[0021] S1. Adjust the position of multiple sets of limiting blocks on the conveying rollers according to the size of the mold to be cleaned, and place the mold to be cleaned between the multiple sets of limiting blocks. Then, drive the conveying rollers to rotate by controlling the operation of the conveying motor. The multiple sets of conveying rollers rotate synchronously under the cooperation of synchronous gears and synchronous toothed belts. The rotation of the multiple sets of conveying rollers supports and moves the mold to be cleaned.

[0022] S2. The mold to be cleaned moves into the airflow dust removal chamber under the action of multiple sets of conveying rollers. Then, the outside air can be compressed and enter the air box by controlling the operation of the compressed fan. It is then transported to multiple dust removal rollers along the conveying air pipe and air guide plate. Compressed air is sprayed into the cavity of the mold to be cleaned by multiple sets of dust removal air nozzles on the outside of the dust removal rollers, thereby initially cleaning the impurities in the cavity of the mold to be cleaned.

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

[0024] S4. In addition, the compressed air in the air box can be blown along the side exhaust pipe and the dust removal limiting plate to the cavity between the molds to be cleaned, so that the impurities blown off between the molds to be cleaned can fall into the impurity storage cavity for collection under the action of the airflow of the dust removal limiting plate and their own gravity. The cleaning liquid in the impurity storage cavity flows into the liquid return cavity after being filtered by the filter plate.

[0025] S5. After the airflow dust removal, the mold to be cleaned can move continuously under the action of multiple sets of conveying rollers. When the mold to be cleaned moves into the mixing 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. Hot steam and cleaning liquid are also sprayed into the cavity of the mold to be cleaned through multiple sets of nozzles, so that the hot steam and cleaning liquid are mixed and cleaned.

[0026] S6. In addition, the cleaning drive motor can be controlled to drive the cleaning transmission gear to rotate. The steam conveying roller and a pair of liquid conveying rollers will rotate under the meshing action of the cleaning transmission gear and the cleaning drive gear. The rotation of the steam conveying roller and the pair of liquid conveying rollers will thoroughly clean the cavity of the mold to be cleaned. The cleaning liquid dripping from the cleaning can be guided along the liquid guide plate.

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

[0028] Compared with the prior art, this utility model can perform multiple cleanings on the blow molding machine mold by cleaning it in stages, which significantly improves the cleaning effect of the blow molding machine mold.

[0029] By using a combination of hot steam and cleaning liquid for cleaning, the consumption of cleaning fluid for blow molding machines is greatly reduced, the cleaning cycle of blow molding machines is shortened, and the convenience of cleaning blow molding machines is improved.

The operation of the liquid delivery pump 312 and the connecting suction pipe 313 extracts and delivers the cleaning liquid in the liquid storage return chamber 229.

[0082] like Figures 1 to 2As shown, a steam pump 314 is fixedly mounted on the top of the housing 203, and a steam extraction pipe 315 connects the steam pump 314 to the liquid storage return chamber 229. The steam pump 314 and the steam extraction pipe 315 work together to transport the cleaning liquid in the liquid storage return chamber 229 to the steam generator 316.

[0083] like Figures 12 to 13 As shown, the outlet of the steam pump 314 is connected to a steam generator 316. The steam generator 316 provides a heating and insulation space for the cleaning liquid.

[0084] like Figures 12 to 13 As shown, multiple sets of heating resistance wires 317 are arranged inside the steam generating chamber 316. The cleaning liquid inside the steam generating chamber 316 is heated by controlling the operation of the heating resistance wires 317, thereby facilitating the formation of hot steam. A steam outlet pipe 318 connects the steam generating chamber 316 and the steam delivery pipe 310. The hot steam inside the steam generating chamber 316 is exported and transported through the steam outlet pipe 318.

[0085] like Figures 7 to 10 As shown, the wiping and drying mechanism 4 is assembled in the drying chamber 207. The wiping and drying mechanism 4 is used to wipe and dry the blow molding die.

[0086] like Figures 7 to 10 As shown, the wiping and drying mechanism 4 includes a drying fixing plate 401. The drying fixing plate 401 serves to limit the assembly of multiple sets of drying rollers 402.

[0087] like Figures 7 to 10 As shown, multiple sets of evenly distributed drying rollers 402 are rotatably mounted inside the drying fixing plate 401. The multiple sets of drying rollers 402 limit the assembly of the wiping sleeve layer 403, and at the same time, hot air can be output and discharged through the drying rollers 402.

[0088] Specifically, air vents are provided on the outer sides of multiple sets of drying rollers 402. By providing air vents, the hot air transported inside the drying rollers 402 is guided, thereby facilitating auxiliary drying of the inner wall of the mold cavity of the blow molding machine.

[0089] like Figures 7 to 10 As shown, each of the multiple sets of drying rollers 402 is fitted with a wiping sleeve 403. The blow molding die is wiped and dried by the rotation of the multiple sets of wiping sleeves 403.

[0090] like Figures 7 to 10As shown, each of the multiple sets of drying rollers 402 located within the drying fixing plate 401 has a drying drive gear 404 fixedly connected to one side, and a drying transmission gear 405 meshes between the multiple sets of drying drive gears 404. The multiple sets of drying rollers 402 rotate through the cooperation of the drying drive gear 404 and the drying transmission gear 405.

[0091] like Figures 7 to 10 As shown, a drying motor 406 is fixedly mounted above the drying fixing plate 401, and the output shaft of the drying motor 406 is connected to the drying transmission gear 405. The drying motor 406 provides power, and the operation of the drying motor 406 drives the drying roller 402 to rotate.

[0092] like Figures 7 to 10 As shown, a drying exhaust plate 407 is arranged above the drying fixing plate 401, and the drying exhaust plate 407 is in communication with multiple sets of drying rollers 402. The drying exhaust plate 407 conducts communication between the multiple sets of drying rollers 402.

[0093] like Figures 7 to 13 As shown, a hot air guide pipe 408 is fixedly connected above the drying exhaust plate 407. The hot air guide pipe 408 connects the heat exchange coil 409 and the drying exhaust plate 407, facilitating the delivery of hot air into the drying exhaust plate 407, thereby improving the drying effect on the inner wall of the mold cavity.

[0094] like Figures 7 to 13 As shown, a heat exchange coil 409 is fixedly connected to one end of the hot air guide pipe 408 outside the drying chamber 207. The heat exchange coil 409 is arranged inside the steam generator 316. Compressed air is heated by circulating within the heat exchange coil 409, thereby facilitating the formation of hot air.

[0095] like Figures 7 to 13 As shown, an exhaust pipe 410 is fixedly connected to the end of the heat exchange coil 409 away from the hot air guide pipe 408, and the exhaust pipe 410 is connected to the air box 222. The exhaust pipe 410 serves to connect the air box 222 and the heat exchange coil 409, so that the compressed air in the air box 222 can be transported to the heat exchange coil 409 along the exhaust pipe 410.

[0096] A method of using a blow molding die cleaning device includes the following steps:

[0097] The positions of multiple sets of limiting blocks 208 on the conveying rollers 202 are adjusted according to the size of the mold to be cleaned, and a mold to be cleaned is placed between the multiple sets of limiting blocks 208. Then, the conveying rollers 202 are 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. The rotation of the multiple sets of conveying rollers 202 supports and moves the mold to be cleaned.

[0098] The mold to be cleaned is moved into the airflow dust removal chamber 205 by multiple sets of conveying rollers 202. Then, by controlling the operation of the compressor fan 223, outside air is compressed and enters the air box 222, and is conveyed along the air conveying pipe 221 and the air guide plate 220 to multiple dust removal rollers 215. Multiple sets of dust removal nozzles 216 on the outside of the dust removal rollers 215 spray compressed air into the cavity of the mold to be cleaned, thereby initially cleaning the impurities in the cavity of the mold to be cleaned.

[0099] Meanwhile, the dust removal transmission gear 218 can be driven to rotate by controlling the operation of the rotary motor 219. Multiple sets of dust removal rollers 215 rotate under the meshing action of the dust removal drive gear 217 and the dust removal transmission gear 218. The rotation of multiple sets of dust removal rollers 215 can be used to perform rotary dust blowing treatment on the mold cavity to be cleaned.

[0100] In addition, the compressed air in the air box 222 can be blown along the side exhaust pipe 224 and the dust removal limiting plate 225 to the cavity between the molds to be cleaned, so that the impurities blown off between the molds to be cleaned can fall into the impurity storage cavity 228 under the action of the airflow of the dust removal limiting plate 225 and their own gravity for collection. The cleaning liquid in the impurity storage cavity 228 flows into the liquid storage return cavity 229 after being filtered by the filter plate 227.

[0101] After being cleaned by airflow dust removal, the mold to be cleaned can move continuously under the action of multiple sets of conveying rollers 202. When the mold to be cleaned moves into the mixing 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. Furthermore, hot steam and cleaning liquid can be sprayed into the cavity of the mold to be cleaned through multiple sets of nozzles 304, so that the hot steam and cleaning liquid can be mixed and cleaned.

[0102] Alternatively, the cleaning drive motor 308 can be controlled to drive the cleaning transmission gear 307 to rotate. The steam conveying roller 302 and a pair of liquid conveying rollers 303 will rotate under the meshing action of the cleaning transmission gear 307 and the cleaning drive gear 306. The rotation of the steam conveying roller 302 and the pair of liquid conveying rollers 303 will thoroughly clean the cavity of the mold to be cleaned. The cleaning liquid dripping from the cleaning can be guided along the liquid guide plate 226.

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

[0104] Meanwhile, some of the compressed air in the air box 222 can be transported to the heat exchange coil 409 through the exhaust pipe 410. After being heated, it is transported to multiple sets of drying rollers 402 through the hot air guide pipe 408 and the drying exhaust plate 407, and discharged through multiple air outlets, thereby assisting in drying the cleaned mold.
