Description

One-step method plastic extrusion blowing make-up machine

Technical field

The utility model relates to one-step method plastic extrusion blowing make-up machine, belongs to the plastics machinery field.Be mainly used in hollow plastic containers such as producing bottle for cosmetics, medicine bottle and beverage bottle.

Background technology

Plastics are extruded the bottle blowing moulding machine, be widely used in producing various bottle for cosmetics, medicine bottle and beverage bottle etc., such machine generally can be divided into the processing of the method for fractional steps or one-step method, method of fractional steps processing is at first extruded plastic raw materials by extruder, to extrude blank again and put into the blow moulding machine blow molding, the shortcoming of this method is that production efficiency is low, and it is many to take the place, workshop.One-step method processing be extrusion molding and blowing on same machine, the production efficiency height.But existing one-step method plastic extrusion blowing make-up machine but exists following shortcoming: the one, and the plastics of extruding are continuous discharging, hocket though bottle blowing machine is two groups, can interruption be arranged still, influence the bottle blowing quality; The 2nd, the blank of extruding enters and is cut off before the blow mold irregularly by scissors, causes the bottleneck slitter edge many, both waste materials, artificial again deburring; The 3rd, the bottle of blow molding falls immediately, influences quality.

Summary of the invention

The purpose of this utility model is in order to overcome the shortcoming of prior art, provides a kind of extruding continuously not influence blow moulding machine and be interrupted blowing, and it is neat to cut off blank, the one-step method plastic extrusion blowing make-up machine of slitter edge free behind the bottle blowing.

The technical scheme of one-step method plastic extrusion blowing make-up machine of the present utility model is: a support is arranged, plastic extruder structure, material cutting mechanism, blow mold and travelling mechanism are installed on the support, are sealed and bottle mechanism, described plastic extruder structure is that motor is through the helix extrusion device behind the deceleration device, pressurizing unit is communicated with feed hopper, pressurizing unit connects water back, and water back connects the blank extrusion; Described blow mold and travelling mechanism are folding mould cylinders, and folding mould cylinder drives template, installation mold in the template; Described seal to be mounted in bottle mechanism seal the air blowing cylinder on the frame, seal to connect under the air blowing cylinder and seal the seated connection head, seal and seal seat and stretching bar under the seated connection head, it is characterized in that the plastic extruder structure connects upper and lower swing arm, swing arm has fulcrum, and swing arm is driven by oscillating cylinder.This programme connects swing arm for the plastic extruder structure, swing arm is under the effect of oscillating cylinder, around discharging opening being raised after the fulcrum rotation, overcome the continuous discharging of extrusion mechanism, and bottle mechanism need be interrupted mobile contradiction, and the blank of extruding is directly entered in the mould, has both guaranteed the bottle blowing quality, shorten the time again, enhance productivity.

One-step method plastic extrusion blowing make-up machine of the present utility model, its described material cutting mechanism is that cylinder is moved in the material cutting that is connected on the frame, material cutting is moved cylinder and is driven support, and the material cutting heating wire is installed on the support, heating wire with extrude blank and contact.Adopt left and right the moving of heating wire to cut off the blank of extruding, make the bottle slitter edge free of moulding, conservation is saved the labour, reduces cost, and improves the quality of products.Folder bottle plate crotch and folder bottle plate are installed on the dual-side of the front and back of template, and the bottle of blow molding is exported after pressing from both sides the bottle plate, and the one, the bottle that falls obtains cooling, ensures the quality of products; The 2nd, output to assigned address.

Its described blow mold and travelling mechanism are two groups and are installed on the sliding floor that under the sliding floor chute is arranged, chute matches with draw runner, and draw runner is installed on the frame, and sliding floor is driven by the traversing cylinder of mould.Make two groups of blow molds and the work of plastic extruder structure matching coordinative.Its seal and bottle mechanism and frame between install before and after governor motion.

The specific embodiment

The utility model discloses a kind of one-step method plastic extrusion blowing make-up machine, a support is arranged, plastic extruder structure, material cutting mechanism, blow mold and travelling mechanism are installed on the support, are sealed and bottle mechanism, as shown in Figure 1, described plastic extruder structure is that motor 1 drives helix extrusion device 3 through deceleration device 2 backs, pressurizing unit is communicated with feed hopper 4, and pressurizing unit connects water back 5, and water back connects blank extrusion 10; Described blow mold and travelling mechanism are folding mould cylinders 13, and folding mould cylinder drives template 12, installation mold in the template; Described seal to be mounted in bottle mechanism seal air blowing cylinder 8 on the frame 6, seal 8 times connections of air blowing cylinder and seal seated connection head 9, seal and seal seat 27 and stretching bar 28 under the seated connection head, its major technology is characterised in that the plastic extruder structure connects upper and lower swing arm 23, swing arm has fulcrum 24, and swing arm is driven by oscillating cylinder 21.Between swing arm 23 and the extrusion mechanism support member 22 that is connected is arranged, when work, the piston rod of oscillating cylinder 21 moves up, extrusion mechanism rising under the drive of swing arm 23, and blank extrusion 10 is raised, and discharging enters mould smoothly continuously.Its described material cutting mechanism such as Fig. 1, Fig. 4, shown in Figure 6 are that cylinder 20 is moved in the material cutting that is connected on the frame, and material cutting is moved cylinder and driven
