[0002] The two-step blow molding machine for manufacturing hollow blow molding containers is used to produce plastic containers. The push rod is inserted into the heated preform and moves the preform along the slide to the mold on the template. After the preform is blown The bottle body is ejected from the mold by opening the left and right templates and flipping the bottom template. The preform transfer device with this structure has the following defects: the mechanism for moving the preform into the mold and the mechanism for removing the mold are independent of each other, which easily makes the actions uncoordinated and the debugging equipment is complicated. ;In the process of ejecting the bottle body from the mold, the left and right templates are required to have a larger opening and closing distance, which increases the moving distance of the template, which not only reduces the efficiency, but also easily wears the parts

Embodiment Construction
[0022] The substantive features of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0023] Such as figure 1 , 4 A preform conveying device shown includes a frame 1 and a template 25 installed on the frame 1, the two ends of the template 25 are provided with guide grooves 11, and one side of the guide groove 11 is provided with a drive assembly. The drive assembly includes a longitudinal drive mechanism 3 and a lateral movement mechanism 4 driven by the longitudinal drive assembly 3. An arm 5 is provided on the transverse movement mechanism 4, and two groups of clamping forks 20 are installed on the arm 5. Two groups of clamping forks 20 are arranged side by side (such as figure 2 , 3 shown); the discharge end of the arm bar 5 is connected to a bottle dial assembly 8; the longitudinal drive mechanism 3 includes a cylinder 9 fixed on the frame 1 and a moving plate 10 driven by the cylinder 9; the ...

The invention relates to a preform transmission device. In the prior art, the actions of shifting a preform in and out of a die are incompatible, which needs a large bottle body pop-up space. The preform transmission device provided by the invention comprises a frame and a template installed on the frame, and is characterized in that two ends of the template are respectively provided with a guide groove; a driving assembly is arranged at one side of the guide groove; the driving assembly comprises a longitudinal driving mechanism and a horizontal moving mechanism, wherein the horizontal moving mechanism is driven by the longitudinal driving mechanism; the horizontal moving mechanism is provided with an arm lever, on which two groups of clamping forks are installed; the two groups of clamping forks are arranged side by side; the movement of the arm lever is controlled by the longitudinal driving mechanism and the horizontal moving mechanism together, thus, the arm lever can be moved in the horizontal plane at random, and the preform and a bottle body can be translated uniformly. The preform transmission device, disclosed by the invention, has the advantages of improving work efficiency, reducing wear-out of machine parts and prolonging service life of machinery.
Description
technical field [0001] The invention relates to a preform conveying device installed on a bottle blowing machine, in particular to a bottle for transferring a heated preform to a blowing station and moving a blown bottle out of the blowing station. Blank transfer arm. Background technique [0002] The two-step blow molding machine for manufacturing hollow blow molding containers produces plastic containers. The push rod is inserted into the heated preform and moves the preform along the slide to the mold on the template. When the preform is blown, the preform is blown. The bottle body is ejected from the mold by opening the left and right templates and flipping the bottom template. The preform transfer device with this structure has the following defects: the mechanism for moving the preform into the mold and the mechanism for moving out of the mold are independent of each other, which easily makes the actions uncoordinated and the debugging equipment is complicated. ; In t...
