[0026] The following is combined with Figure 1-4 This application is described in further detail.

[0027] The present application embodiment discloses a blow molding machine based on plastic barrel production. Figure 1-4A blow molding machine based on plastic barrel production includes a base 1 and two half molds 2 arranged at the top of the base 1, support blocks 3 are fixed on both sides of the top of the base 1, the support block 3 is fixedly connected to the half mold 2 through an electric telescopic rod 4, an L-shaped plate 5 is fixed to the top of the support block 3, a U-shaped frame 6 is fixed to the horizontal end of the L-shaped plate 5, a cross bar 7 is inserted and connected to one side of the U-shaped frame 6, the cross bar 7 is connected to the U-shaped frame 6 through an elastic component 8, a collision plate 9 is fixed to the end of the cross bar 7 close to the half mold 2, both ends of the U-shaped frame 6 are rotatably connected with a seesaw 10, and the corresponding ends of the two seesaws 10 are fixed with a vibration block 11, and the seesaw 10 is connected to the cross bar 7 through a linkage component 12.

[0028] In the present embodiment, when the plastic barrel is blow-molded, the movement of the electric telescopic rod 4 drives the two half molds 2 to move toward each other and close the mold, and then the plastic preform is injected into the half mold 2 by the screw extruder, and then the plastic preform is blow-molded by the inflation system. The screw extruder and the inflation system are both existing structures of the blow molding machine, so this application does not go into details. When the plastic barrel is demolded after blow molding, the reverse movement of the electric telescopic rod 4 drives the two half molds 2 to move to both sides. The half mold 2 hits the impact plate 9 during movement, and the impact plate 9 drives the movement of the cross bar 7. At the same time, with the cooperation of the elastic component 8, the reciprocating motion of the cross bar 7 can be driven. The cross bar 7 drives the movement of the linkage component 12, which can drive the reciprocating swing of the seesaw 10. The seesaw 10 drives the reciprocating motion of the vibration block 11, and the half mold 2 can be continuously knocked by the vibration block 11. Under the knocking vibration, the separation and demoulding of the half mold 2 and the plastic barrel are convenient, which is convenient for the unloading of the plastic barrel and improves the unloading efficiency of the plastic barrel.

[0029] In a further embodiment, Figure 2 As shown, the elastic component 8 includes a connecting plate 81 fixedly arranged at one end of the cross bar 7, and the connecting plate 81 is fixedly connected to the U-shaped frame 6 through a first spring 82. The linkage component 12 includes a first connecting rod 121 sleeved on the outer wall of the cross bar 7, and both ends of the first connecting rod 121 are hinged with a second connecting rod 122 hinged to the rocker 10.

[0030] When the electric telescopic rod 4 drives the half mold 2 to part the mold, when the half mold 2 moves outward, the half mold 2 hits the impact plate 9, and the impact plate 9 drives the movement of the cross bar 7. The cross bar 7 stretches the first spring 82 through the connecting plate 81. When the half mold 2 moves inward, under the elastic action of the first spring 82, the cross bar 7 can be driven to reset, thereby driving the reciprocating motion of the cross bar 7. The cross bar 7 drives the reciprocating motion of the first connecting rod 121, and the first connecting rod 121 drives the reciprocating motion of the second connecting rod 122, thereby driving the reciprocating swing of the seesaw 10. The seesaw 10 drives the reciprocating swing of the vibration block 11, and the vibration block 11 can be used to continuously knock and vibrate the half mold 2, so as to facilitate the disassembly and separation of the half mold 2 and the plastic barrel, facilitate the unloading of the plastic barrel, and improve the unloading efficiency of the plastic barrel.

[0031] In a further preferred embodiment of the present invention, Figure 1 As shown, a pad 13 is fixed to one side of the base 1, and a discharge plate 14 is rotatably connected to the top of the pad 13. A rotating component 15 for driving the discharge plate 14 to rotate is provided on the pad 13. An air duct 16 is fixed to one side of the top of the pad 13, and a fan 17 is connected to the top of the air duct 16. A side of the air duct 16 facing the discharge plate 14 is connected to multiple blowing heads 18.

[0032] After the plastic barrel is demoulded and unloaded, the plastic barrel is placed on the discharge plate 14. Then, the movement of the rotating component 15 drives the rotation of the discharge plate 14, which can drive the rotation of the plastic barrel. At the same time, under the operation of the fan 17, ventilation is ventilated to the air duct 16, and then blown out through the blowing head 18, so that the surface of the plastic barrel can be cooled by blowing, which facilitates the all-round rapid cooling of the plastic barrel and improves the cooling efficiency of the plastic barrel.

[0033] In a further embodiment, Figure 3-4 As shown, the rotating assembly 15 includes a driving motor 151 fixedly arranged at the bottom end of the pad 13, the output shaft of the driving motor 151 is fixed with a driving wheel 152, the outer wall of the discharge plate 14 is sleeved with a driven wheel 153 meshing with the driving wheel 152, the top of the discharge plate 14 is provided with a switch assembly 19, the switch assembly 19 includes a groove 191 opened at the top of the discharge plate 14, a self-resetting switch 192 electrically connected to the fan 17 and the driving motor 151 is fixed in the groove 191, the top of the self-resetting switch 192 is fixed with a pressing plate 193 interlaced with the groove 191, and the pressing plate 193 is fixedly connected to the groove 191 through a second spring 194.

[0034] When the plastic barrel is placed on the discharge plate 14, the gravity of the plastic barrel drives the pressure plate 193 to move downward. During the movement, the pressure plate 193 squeezes the self-resetting switch 192, and the self-resetting switch 192 can turn on the fan 17 and the drive motor 151. During operation, the fan 17 ventilates the air duct 16 and then blows it out through the blowing head 18.

[0035] The implementation principle of the blow molding machine based on the production of plastic barrels in the embodiment of the present application is as follows: when the plastic barrel needs to be demolded and disassembled during blow molding, the half mold 2 is driven to move outward under the movement of the electric telescopic rod 4, and the half mold 2 hits the impact plate 9, and the impact plate 9 drives the movement of the cross bar 7, and the cross bar 7 stretches the first spring 82 through the connecting plate 81. When the half mold 2 moves inward, under the elastic action of the first spring 82, the cross bar 7 can be driven to reset, thereby driving the reciprocating motion of the cross bar 7, and the cross bar 7 drives the reciprocating motion of the first connecting rod 121, and the first connecting rod 121 drives the reciprocating motion of the second connecting rod 122, thereby driving the reciprocating swing of the seesaw 10, and the seesaw 10 drives the reciprocating swing of the vibration block 11, and the vibration block 11 can be used to continuously knock and vibrate the half mold 2, so that the half mold 2 and The disassembly and separation of the plastic barrel facilitates the unloading of the plastic barrel and improves the unloading efficiency of the plastic barrel. After the plastic barrel is unloaded, it is placed on the discharge plate 14. Under the action of gravity of the plastic barrel, the pressure plate 193 is driven to move downward. During the movement of the pressure plate 193, the self-resetting switch 192 is squeezed. The self-resetting switch 192 can turn on the fan 17 and the drive motor 151. During operation, the fan 17 ventilates the air duct 16 and then blows it out through the blowing head 18. During operation, the drive motor 151 drives the active wheel 152 to rotate, and the active wheel 152 drives the driven wheel 153 to rotate. The driven wheel 153 drives the discharge plate 14 to rotate. The discharge plate 14 drives the rotation of the plastic barrel.
