Description
Heating of pipe blank device when the utility model relates to two-step method production hollow plastic container.
Adopt injection, stretch-blow two-step method to produce the hollow plastic packing container,, the pipe of injection moulding is needed heating before stretch blow as mineral water bottle, drinking-water engine room etc.The existing device that is used for the plastic pipe heating has fixed or rotary, for small container, and bottle for cosmetics for example, Coke bottle etc., once heating can reach requirement in above-mentioned heater.But if big bottle container, as three gallons, five gallon bottle drinking-water engine room, owing to pipe height, wall thickness, heater commonly used does not reach desirable purpose.Because heating of pipe blank should make inside and outside wall heat penetration, but when heating again according to plastic properties, can not temperature too high, excessive velocities.So have only heating of the branch mailbox of employing or the heating of long zone.So-called branch mailbox heating (fixed), be exactly a case as preheating cabinet, the another case is at first put into preheating cabinet with plastic pipe by an artificial ground as heating cabinet, case inner control temperature is lower, the long period preheating.After being preheating to a certain degree, by manually pipe being moved on in the heating cabinet from preheating cabinet, heating the temperature inside the box is controlled higherly, reaches until adding heat request, goes up stretch blow machined moulding then again.Therefore, this method equipment investment is big, troublesome poeration, heat inhomogeneous, the production cost height, the cycle is long, efficient is low, qualified rate variance.Be useful on the rotary heating of pipe blank device of big bottle container, needed to prolong heating region, carried out strict temperature control debugging, its difficulty is very big, and is very time-consuming, and owing to the arrangement of heating tube is fixed, pipe a certain period of when operation from start to finish facing to heating tube, and a certain section all the time to not heating tube, so heat inhomogeneously, the segmentation temperature difference in same the pipe appears, cause local deformation easily, bending, the difficulty when having increased stretch blow, product percent of pass is low.
The purpose of this utility model is the defective that overcomes in the prior art, provides a kind of revolving, and heating tube is installed in the middle of the ring rotation mechanism, subregional heating apparatus for plastic pipe.
Plastic pipe subregion heater of the present utility model, a frame is arranged, power and transmission mechanism are installed in the frame, transmission mechanism drives conveying mechanism, the pipe supporting base is installed on the annular swivel-chain of conveying mechanism, on the intermediate stand of annular swivel-chain heater is installed, heater is made up of heating tube support and heating tube, heater in the middle of its described annular swivel-chain is divided into two intervals, one is the preheating zone, another is the thermal treatment zone, has plastic pipe to take, put the operating space between the preheating zone and the thermal treatment zone.
Plastic pipe subregion heater of the present utility model, its described conveying mechanism is driving shaft, driving wheel and driven shaft, the driven pulley that transmission mechanism drives, and annular swivel-chain is formed, the annular swivel-chain links to each other with adapter sleeve, the pipe supporting base is installed in the adapter sleeve, and the retaining heat reflection plate is installed in two outsides of annular swivel-chain respectively.
Plastic pipe subregion heater of the present utility model has heating tube support and heating tube in its preheating zone, heating tube support and heating tube are arranged in the thermal treatment zone, and both are independent.
The utility model discloses a kind of heating apparatus for plastic pipe, compared with the prior art, have following characteristics: the one, whole heater is divided into two parts, form two heating regions, preheating is mainly carried out to pipe in a zone, regulates temperature roughly, and temperature can suitably be controlled at low, save debug time, reduced investment a bit.Another zone is the thermal treatment zone, but heating of pipe blank is arrived the stretch blow degree, regulates trouble, the temperature control strictness, but because scope is dwindled relatively, just reach easily.The 2nd, mainly be applicable to the heating of big bottle pipe, whole pipe is long, holds up height, so heating tube position height can suitably be arranged, for example mainly the pipe stage casing is heated in the preheating zone, the then relatively upper and lower heat that adds is big in the thermal treatment zone, and the stage casing is low, and is perhaps high and low different in each root heating tube installation site of the preheating zone and the thermal treatment zone, plastic pipe is heated evenly, avoid a certain section over-heating, and another section underheat phenomenon can overcome the pipe bending simultaneously.The 3rd, whole heating process simple to operate, and heating tube is arranged flexibly, can heat according to plastic properties, and effective, the product percent of pass height.
Fig. 1 is the utility model plastic pipe subregion heater schematic top plan view;
Fig. 2 is the utility model plastic pipe subregion heater side schematic view.
Below in conjunction with Fig. 1-Fig. 2 embodiment of the present utility model is done detailed explanation.
1, frame; 2, driving shaft; 3, driving wheel; 4,6,7, heating tube support; 5,8,10, heating tube (as adopting infrared tube); 9, annular swivel-chain; 11, pipe supporting base; 12, driven shaft; 13, driven pulley; 14, retaining heat reflection plate; 15, preheating zone; 16, pipe supporting base; 17, plastic pipe takes, puts the operating space; 18, the thermal treatment zone; 19, power; 20, transmission mechanism; 21,21 ', 21 " plastic pipes; 22, adapter sleeve; 23, rotating gear.
The utility model is a kind of two-step method heating of pipe blank device when producing hollow plastic container, drive driving shaft 2, driving wheel 3 by the power 19 that is installed in the frame 1 through transmission mechanism 20, driving wheel 3 with from main wheel 13 annular swivel-chain 9 is installed, one side of annular swivel-chain 9 is installed adapter sleeve 22, pipe supporting base 11,16 is installed in the adapter sleeve 22, place the plastic pipe 21 that needs heating on the pipe supporting base, above-mentioned is whole conveying mechanism.From Fig. 1, shown in Figure 2, heater is installed in the middle of the pool conveyer structure, and it is two groups, one group is that heating tube support 4,6 and heating tube 5 are formed the thermal treatment zone 18, another group is that heating tube support 7 and heating tube 8,10 are formed preheating zone 15, the retaining heat reflection plate 14 that comprises both sides has plastic pipe to take, put operating space 17 between the thermal treatment zone 18 and preheating zone 15.The people is in the position, operating space during production, the plastic pipe 21 that is come out in the thermal treatment zone 18, and " take out, will need the plastic pipe 21 that heats ' put again, plastic pipe 21 enters the thermal treatment zone 18 after 15 preheatings of preheating zone, and heating is produced continuously.In preheating with add and pine for, plastic pipe needs continuous rotation along with annular swivel-chain 9 revolution the time, therefore, 11 times rotating gear 23 is installed at the pipe supporting base, rotating gear 23 cooperates with chain or tooth bar etc., rotate, make plastic pipe 21,22 ', 21 " constantly rotations.
