Abstract
The utility model discloses a double-line drawing blowing make-up machine, composed of a machine base, a machine frame, a mould locked mechanism, a drawing mechanism, a control system of gas circuit and electrocircuit, etc. The drawing mechanism is a double-line drawing cylinder, the piston in the double-line drawing cylinder is connected with a drawing rod, that is to say, a piston rod and the drawing rod are the same rod. The utility model uses two drawing cylinders in parallel to directly drive two drawing rods, which saves a connecting plate and a guiding mechanism, overcomes the defects that drawing and blowing are out of synchronism, single drawing rod is difficult to adjust, etc., and improves the rate of certified products of drawing and blowing.
Description
The utility model relates to stretch blow moulding.
With polyester such as PET is raw material, through the packing container of injection stretch blow molding, has the intensity height, and good airproof performance, and characteristics such as transparent are widely used.The production equipment of said vesse has injection, stretch-blow to process on the same stage, also has injection and two step of stretch-blow extension set to produce.But no matter be which kind of equipment, drawing mechanism in its prior art, piston rod by a draft cylinder connects a gusset piece, gusset piece drives the stretching bar, moving back and forth of gusset piece needs guiding mechanism, as Chinese patent: 86104834,88221296.6,91227938.9,92200444.7 and 92208227.8 etc.The defective of the said equipment drawing mechanism has: the one, the support of a special use will be arranged on support, and for draft cylinder is installed, the complete machine height is increased, occupy bigger space; The 2nd, the motion that gusset piece drives the stretching bar needs guiding mechanism, and bigger resistance is arranged, and increases power consumption; The 3rd, by a draft cylinder, by generally being to drive the bar that stretches more than two or two behind the gusset piece, the stretching bar easily produces distortion, can produce stretchings, air blowing is asynchronous, and wants a certain adjusting very difficultly, influences product quality.
The purpose of this utility model is that design is a kind of with each root stretching bar, directly drive by a draft cylinder, do not need gusset piece and guiding mechanism, undesired can the adjusting separately of operation appears according to a certain stretching bar, thereby overcome stretching, blow asynchronously, reduce the double-row type stretch blow moulding of product percent defective.
The technical scheme of the utility model double-row type stretch blow moulding is: institute such as, electric control system gentle by support, frame, clamping mechanism, drawing mechanism forms; its so-called drawing mechanism is the biserial draft cylinder, and the piston in the draft cylinder connects the stretching bar.
Double-row type stretch blow moulding of the present utility model, the piston rod of draft cylinder and stretching bar consubstantiality in its drawing mechanism.
The utility model is a kind of double-row type stretch blow moulding, with in the drawing mechanism by two draft cylinders arranged side by side, directly drive two stretching bars, compared with the prior art, have stretching, blow and use flexibly, the length of gassing time, morning can be regulated arbitrarily separately late separately, can satisfy the needs of bulk container, big air-blowing quantity especially, and make stretching, air blowing synchronously, improve the qualification rate of goods; Save gusset piece and guiding mechanism between draft cylinder and the stretching bar, simple in structure without the mounting bracket of draft cylinder, resistance is few, and is low in energy consumption.
Fig. 1 is the utility model double-row type stretch blow moulding drawing mechanism schematic diagram;
Fig. 2 is the utility model double-row type stretch blow moulding schematic diagram.
Below in conjunction with Fig. 1-Fig. 2 an embodiment of the present utility model is done detailed explanation.
1, draft cylinder loam cake; 2,2 ' draft cylinder; 3,3 ' piston; 4,4 ' stretching bar; 5, draft cylinder lower cover; 6, sealing cylinder; 7, seal piston; 8, frame; 9, support; 10, drawing-die piece; 11, adjusting screw(rod); 12, curved arm rod; 13, matched moulds cylinder; 14, collapsible form; 15, drawing-die bar; 16, preceding solid plate; 17, parallel bar; 18, rear fixed plate.
The utility model relates to the double-row type stretch blow moulding, promptly by two draft cylinders of installing side by side 2,2 ', piston 3,3 ' directly in the draft cylinder connect stretching bar 4,4 ', so the stretching bar also is two, 6 two of sealing cylinders, stretching bar 4,4 ' pass seal piston 7 in the sealing cylinder, more than form stretch blow mechanism, be equipped with gas circuit, circuit control, finish the stretch blow function.With the matched moulds cylinder 13 in the support 9, by transmissions such as curved arm rod 12, adjusting screw(rod)s 11, drive drawing-die bar 15, collapsible form 14 is moved under the guiding of parallel bar 17, mould is installed on collapsible form 14 and the rear fixed plate 18, the fixation of solid plate 16 and drawing-die piece 10 is finished the locked mode function before relying on again.
Claims (2)
1, double-row type stretch blow moulding;, electric control system gentle by support, frame, clamping mechanism, drawing mechanism formed; it is characterized in that drawing mechanism is biserial draft cylinder (2,2 '), the piston (3,3 ') in the draft cylinder connects stretching bar (4,4 ').
2, double-row type stretch blow moulding as claimed in claim 1 is characterized in that the piston rod and stretching bar (4, the 4 ') consubstantiality of draft cylinder (2,2 ').
