Referring to fig. 1 to 12, in the case of performing blow molding production of a plastic bottle using the bottle blowing machine of the present invention:

The longitudinal die 400 continuously extrudes plastic blanks from the extrusion ports 441 of the two extrusion end caps 440 upwards: the feeding holes 411 are connected with an extruder, and the blanks in a hot-melting state enter from the two feeding holes 411 and are extruded from the extrusion port 441 through the extrusion channel. The air inlet of the nozzle adjusting rod 461 is connected with an air supply device, and a certain amount of air is injected into the bottle blank while the bottle blank is extruded, so that the bottle blank keeps bulging, and subsequent extrusion molding is facilitated.

In the process, the screw rod of the power mechanism is driven by the servo motor to rotate, the two extrusion nozzle adjusting rods 461 are driven by the screw rod nut and the nut mounting plate to slide up and down in the extrusion rod 430, and the distance between the upper ends of the extrusion nozzle adjusting rods 461 and the extrusion port 441 of the extrusion end cover 440 is changed, so that the wall thickness of a plastic bottle blank extruded from the extrusion port 441 can be adjusted according to the shape requirement of the plastic bottle.

The mold opening and closing assembly 100 is clamped between the two circulation guide rails 220 by the guide wheel mechanisms 150 at the left and right ends. The two guide rollers 152 of the guide wheel mechanism 150 always roll along the inner side and the outer side of the circulating guide rail 220, respectively, and the rolling wheels 153 always abut against the end surface of the circulating guide rail 220.

When viewed from left to right, the driving plate 210 rotates around its axis at a constant speed in a counterclockwise direction, the driving rod 230 fixedly mounted on the driving plate 210 moves along with it, and the driving rod 230 drives the mold opening and closing assembly 100 to move along the circulating guide rail 220 through the driving block 240.

In the process that the mold opening and closing assembly 100 moves along the circulation guide rail 220, the distance between the guide rod 120 of the mold opening and closing assembly 100 and the axis of the driving plate 210 changes, and the driving block 240 is always slidably sleeved on the driving rod 230: when the distance between the guide rod 120 of the mold opening and closing assembly 100 and the axis of the driving plate 210 increases, the driving block 240 slides to one end of the driving rod 230 away from the axis of the driving plate 210; when the distance between the guide rod 120 of the mold opening and closing assembly 100 and the axis of the driving plate 210 decreases, the driving block 240 slides toward the other end of the driving rod 230.

The guide wheel mechanism 150 is disposed at two ends of the two guide rods 120 of the mold opening and closing assembly 100, and in the process that the mold opening and closing assembly 100 moves along the circulation guide rail 220, the two guide rollers 152 of the guide wheel mechanism 150 always roll along the inner side and the outer side of the circulation guide rail 220 respectively. When the mold opening and closing assembly 100 moves to the straight line section of the circulating guide rail 220 arranged along the up-down direction, the mold opening and closing assembly 100 moves along a straight line, the first opening and closing mold plate 310 and the second opening and closing mold plate 320 fixedly installed on the mold mounting plate 140 also move along a straight line, and the length direction of the molding cavity keeps moving vertically from bottom to top.

The longitudinal die head 400 is arranged between the straight segments of the two circulating guide rails 220, and the first opening and closing die plate 310 and the second opening and closing die plate 320 keep moving in the same direction from bottom to top with the extruded blank in the straight segments of the circulating guide rails 220. In this case, the extrusion directions of the two extruded blanks need to be adjusted according to the positions of the two molding cavities when the first opening/closing die plate 310 and the second opening/closing die plate 320 are closed, so that the plastic bottle blanks extruded from the extrusion port 441 can be positioned in the molding cavities as closely as possible during the closing. Specifically, the method comprises the following steps: when the extrusion end cover 440 not provided with the top block installation groove 412 is adjusted: a screw which is installed in an adjusting screw hole of the fixed cover plate through adjusting threads enables one end of the screw to be abutted against the extrusion end cover 440; and simultaneously, the position of the adjusting wedge 450 is changed by adjusting a screw which is installed in the screw through hole and is in threaded connection with the adjusting wedge 450. Under the action of the inclined surfaces of the two adjusting wedges 450 and the screws in the adjusting screw holes, the right extrusion end cover 440 moves on the extrusion end surface, so that the inner cavity of the extrusion end cover 440 deviates relative to the upper part of the extrusion rod 430, and the extrusion effect is adjusted. Specifically, when adjusting the extrusion end cap 440 provided with the top block installation groove 412: besides adjusting the adjusting wedge 450, a screw installed in an adjusting screw hole of the fixed box 410 through an adjusting thread is needed, so that one end of the screw abuts against the movable top block 470, and the movable top block 470 abuts against the extrusion end cover 440 through a pressing portion thereof, thereby performing translational adjustment on the extrusion end cover 440.

When the mold needs to be opened, the two mold closing cylinders 130 act to drive the two mold mounting plates 140 to respectively slide towards two sides, so that the first opening and closing mold plate 310 and the second opening and closing mold plate 320 open and separate towards two sides.
