[0018] The present invention also discloses a molding method based on a hollow blow molding device for a pesticide packaging barrel, which specifically comprises the following steps:

[0019] Step 1: The user adjusts the position of the mold assembly through the electric slide rail so that the molds that are molded together move to the lower end of the discharge side of the extruder, and the cylindrical plastic extruded by the extruder gradually falls into the feeding slot on the upper side of the mold of the two combined molds.

The height of the movable plate and the nozzle is adjusted by the electric push rod assembly so that the nozzle is inserted into the inner end of the top of the cylindrical plastic. The compressed air generated by the air compressor is injected into the inside of the cylindrical plastic through the conduit and the nozzle. The cylindrical plastic expands under the action of the compressed air and is formed under the action of the inner film cavity of the two sets of molds. The two sets of molds are separated by the two sets of first cylinders. The formed packaging barrel falls into the recycling box under the action of gravity, and then each link is reset;

[0020] Step 2: In step 1, the tubular plastic will closely fit with the mold cavities of the two sets of molds during expansion, which will cause residual plastic to adhere to the mold cavities. When the hollow blow molding production process is interrupted, the electric slide rail adjusts the position of the mold assembly to the lower side of the cleaning part to close the two sets of molds, and adjusts the height of the support frame, the rotating column, and the adjusting part through the hydraulic cylinder assembly, so that the rotating column and the adjusting part are partially inserted into the inner side of the mold of the two combined molds through the feed trough, and the bottom of the scraper frame is fitted with the mold cavity in the mold.

[0021] Step three: In step two, while the scraper frame is scraping the inner wall of the mold, the liquid pump draws external cleaning liquid through the liquid extraction pipe and sprays it through the connecting pipe, the receiving pipe, the injection pipe, and the spray frame. The sprayed cleaning liquid is sprayed on the scraper frame surface and the inner wall of the mold respectively to promote the removal of residual materials attached to the surfaces of both. After the cleaning operation is completed, the two sets of molds are separated, and the cleaning impurities flow down with the cleaning liquid through the mold separation end and fall into the receiving box, so that each link is reset, and the two sets of molds that have been cleaned are closed again and the nozzles are inserted into the two sets of molds, and the air compressor generates compressed air to blow the inner wall of the mold through the duct and the nozzle to accelerate the evaporation of moisture on the inner wall of the mold.

[0050] The present invention also discloses a hollow blow molding device and a molding method based on a pesticide packaging barrel, which specifically comprises the following steps:

[0051] Step 1: The user places a recycling box between the two groups of receiving boxes 7, and adjusts the position of the mold assembly 3 through the electric slide rail 2, so that the molds 33 that are molded together in the mold assembly 3 are moved to the lower end of the discharge side of the extruder 4, and the corresponding raw materials are injected into the extruder 4. The extruder 4 melts and extrude the raw materials, and the extruded cylindrical plastic gradually falls into the feeding trough on the upper side of the mold 33 of the two combined molds. The extruder 4 is a prior art, and its internal specific structure and working principle are not described in detail. After the cylindrical plastic is introduced, the two groups of second cylinders 34 are started, and the two groups of second cylinders 34 adjust the positions of the two groups of blades 35, so that the two groups of blades 35 cut the cylindrical plastic on the upper side of the mold 33, and the position of the mold assembly 3 and the cylindrical plastic retained in the mold 33 is adjusted by the electric slide rail 2, so that the top of the cylindrical plastic is At the bottom of the blow molding end of the blow molding part 5, at this time, another group of molds 33 in the mold assembly 3 is located at the lower side of the extruder 4, and the above injection molding operation is repeated. The height of the movable plate 54 and the nozzle 55 is adjusted by the electric push rod assembly 53, so that the nozzle 55 is inserted into the inner end of the top of the cylindrical plastic, and the air compressor 51 is started. The compressed air generated by the air compressor 51 is injected into the inside of the cylindrical plastic through the conduit 52 and the nozzle 55. The cylindrical plastic expands under the action of the compressed air, and the inner film cavities of the two groups of molds 33 provide support for the outer molding of the cylindrical plastic. After the cylindrical plastic is formed into a packaging barrel, the two groups of molds 33 are separated by the two groups of first cylinders 32. The formed packaging barrel falls into the recycling box under the action of gravity, and then each link is reset. At this time, another group of molds 33 is located at the lower side of the blow molding part 5, and the above blow molding operation is repeated to realize continuous blow molding operation;

[0052] Step 2: In step 1, during the process of compressed air expansion introduced into the cylindrical plastic, its outer surface will be closely attached to the inner mold cavity of the two sets of molds 33. During the continuous hollow blow molding process, plastic residue will be attached to the mold cavity. When the hollow blow molding production process is interrupted, the electric slide rail 2 is used to adjust the position of the mold assembly 3 so that the two matching sets of molds 33 in the mold assembly 3 are moved to the lower side of the cleaning member 6, and the two sets of molds 33 are closed by the two sets of first cylinders 32. The height of the support frame 62, the rotating column 63, and the adjusting member 65 are adjusted by the hydraulic cylinder assembly 61, so that the rotating column 63 and the adjusting member 65 are partially inserted into the inner side of the mold 33 of the two combined molds through the feed trough, and the scraper is allowed to remove the plastic residue. The bottom of the frame 657 is fitted with the inner cavity of the mold 33, and the second motor 651 is started. The second motor 651 drives the two sets of screws 653 to rotate through the two sets of bevel gear assemblies 652 respectively. The two sets of screws 653 drive the two sets of sliding frames 654, a set of spraying frames 6555, and the scraping frame 657 to slide. After the side of the scraping frame 657 is fitted with the inner wall of the mold 33, the second motor 651 is turned off and the first motor 641 is started. The first motor 641 drives the rotating column 63, the sliding frame 654, the spraying frame 6555, and the scraping frame 657 to rotate through the gear 642 and the gear ring 643, so that the scraping frame 657 scrapes and cleans the plastic residues attached to the inner walls of the two sets of molds 33;

[0053] Step three: in step two, while the scraping frame 657 is scraping the inner wall of the mold 33, the liquid pump 6551 is started, and the liquid pump 6551 extracts external cleaning liquid through the liquid extraction pipe, and then the cleaning liquid is sprayed out through the connecting pipe 6552, the receiving pipe 6553, the injection pipe 6554, and the spray frame 6555. The spray frame 6555 sprays the cleaning liquid to spray the surface of the scraping frame 657 and the inner wall of the mold 33 respectively, so as to promote the falling off of the residual material attached to the surfaces of both. After the cleaning operation is completed, the two groups of molds 33 are separated, and the cleaning impurities flow down with the cleaning liquid through the mold separation end of the mold 33 and fall into the receiving box 7, so as to realize the cleaning of the inner wall of the mold 33 and the recovery of impurities, so as to reset each link, so as to close the two groups of molds 33 after cleaning again and insert the nozzle 55 into the two groups of molds 33, so as to allow the air compressor 51 to generate compressed air to blow the inner wall of the mold 33 through the conduit 52 and the nozzle 55, so as to accelerate the evaporation of water on the inner wall of the mold 33 by accelerating the air flow rate.

[0054] At the same time, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.
