Blow molding machine is a kind of bottle blowing machine, which can also be called plastic blow molding machine or hollow blow molding machine. However, the existing bottle blow molding machine has some shortcomings, such as: Application number: CN202321752259.2 A blow molding machine for producing bottles, wherein the blow-molded bottles fall onto the top of a flip plate after demoulding, and the flip plate is pressed to press the torsion spring, so that the rotating shaft and the flip plate rotate, so that the bottles slide from the surface of the flip plate to the top of the inclined plate, and slide through the surface of the inclined plate to the inside of the collection box, thereby reducing the impact force of the falling bottles, preventing the bottles from falling directly, causing deformation or damage to the bottles, and reducing the generation of defective products, thereby achieving the goal of improving the production quality of bottles. However, in actual use, since the equipment does not have a bottle embryo manufacturing mechanism, it may cause the equipment to be used.

Working principle: When using the blow molding machine for producing bottles, firstly, the first motor 3 is used to drive the feeding mechanism to operate, so that the feeding mechanism transmits the plastic particles to the extruder 9, so that the extruder 9 extrude the bottle embryo, and then the first motor 3 is rotated in the positive direction to drive the moving mechanism to operate, so that the moving mechanism drives the two sets of molds 26 to move to the bottom of the extruder 9, and then the first motor 3 is rotated in the reverse direction to drive the merging mechanism to operate, so that the merging mechanism pushes the two sets of molds 26 to merge, so that the two sets of molds 26 clamp the bottle embryo, and at the same time, when in use, the first motor 3 is rotated in the positive direction to drive the moving mechanism to operate, so that The moving mechanism moves the mold 26 and the preform to the bottom of the exhaust port 35, and then the second motor 27 is rotated forward to drive the positioning mechanism to operate, so that the positioning mechanism moves the exhaust port 35 to the specified position, and then the second motor 27 is rotated reversely to drive the air intake mechanism to operate, so that the air intake mechanism transmits gas to the exhaust port 35, so that the exhaust port 35 transmits gas to the preform inside the mold 26 for blow molding. When the blow molding of the preform is completed, the first motor 3 drives the merging mechanism to operate, so that the merging mechanism separates the two sets of molds 26, so that the bottle falls out of the bottom of the device body 1 to complete the blow molding; When the first motor 3 rotates, it drives the first sprocket 4 to rotate, so that the first sprocket 4 drives the second sprocket 6 and the auger shaft 7 to rotate through the first chain 5, so that the auger shaft 7 transfers the raw materials in the feed pipe 8 to the inside of the extruder 9; When the first motor 3 rotates in the forward direction, the ratchet set at the right end of the third sprocket 12 will be meshed, that is, the first ratchet 15 is meshed with the second ratchet 16, and the second ratchet 16 drives the first reciprocating screw 18 to rotate through the spring shaft 17, and because the ratchet set at the right end of the third sprocket 12 and the ratchet set at the right end of the fourth sprocket 14 are in opposite directions, the ratchet set at the right end of the fourth sprocket 14 will be disengaged, that is, the first ratchet 15 is disengaged from the second ratchet 16, and the second ratchet 16 retreats under the drive of the spring shaft 17, so that the fourth sprocket 14 cannot drive the convex groove rod 21 to rotate; When the first motor 3 rotates forward, it will drive the first reciprocating screw 18 to rotate, so that the first reciprocating screw 18 drives the moving shell 19 to move linearly, so that the moving shell 19 drives the mold 26 to move, and when the first motor 3 rotates in the reverse direction, it will cause the fourth sprocket 14 to drive the convex groove rod 21 to rotate, so that the convex groove rod 21 drives the first bevel gear 22 to rotate, so that the first bevel gear 22 drives the second bevel gear 23 to rotate, so that the second bevel gear 23 drives the second reciprocating screw 24 to rotate, so that the two sets of screw sleeves 25 move toward each other, so that the screw sleeves 25 drive the mold 26 to merge or separate, and because the first bevel gear 22 is connected to the moving shell 19 through the bearing seat, when the moving shell 19 moves, the first bevel gear 22 will also move with it; When the second motor 27 rotates in the forward direction, the ratchet set at the left end of the fifth sprocket 28 will be meshed, causing the ratchet set at the left end of the sixth sprocket 30 to be disengaged, so that the fifth sprocket 28 drives the reciprocating threaded shaft 31 to rotate, so that the reciprocating threaded shaft 31 drives the threaded sleeve 32 to move, so that the threaded sleeve 32 drives the fixing plate 33 and the electric push rod 34 to move, and when the exhaust port 35 is adjusted in height, the exhaust port 35 can be driven by the electric push rod 34 to adjust its height; When the second motor 27 rotates, the sixth sprocket 30 drives the third bevel gear 36 to rotate, so that the third bevel gear 36 drives the fourth bevel gear 37 and the peristaltic pump rod 38 to rotate, so that the peristaltic pump rod 38 cooperates with the peristaltic pump housing 39 to squeeze the transmission tube 40, so that the gas inside the air storage box 41 is transmitted to the exhaust port 35 through the transmission tube 40.
