Description

The mouth cutting mechanism of automatic blow-molding bottle blowing machine

Technical field

The present invention relates to a kind of mouth cutting mechanism of automatic blow-molding bottle blowing machine, play a part to belong to the auxiliary body that is matched on the automatic blow-molding bottle blowing machine being retained in the technology overlap on the bottleneck after the bottle blow molding or claiming the excision of technology slitter edge.

Background technology

Automatic blow-molding bottle blowing machine can be blown various bottles efficiently, and this is self-evident.But because the bottleneck of technological reason behind blow molding all leaves overlap, this overlap is accustomed to being called slitter edge again, it need be excised when blowing such as bottles such as wide-mouth bottle, dairy produce bottles.To the excision of bottleneck overlap comparatively traditional be to adopt hand cut, the problem of bringing is, drop into that manpower is many, operating efficiency lowly, otch just do not advising; And comparatively advanced be that the employing machine is cut, after the blowing bottle blowing machine is finished the bottle blowing, be transported to and establish cutting on the bottleneck machine of a place in addition and excise overlap, though the rule of efficient and otch just are better than the former in the degree aspect, but separate with the blowing bottle blowing machine owing to cut the bottleneck machine, thereby just there is a movement process inevitably, it also needs corresponding movement human input, perhaps, also need special operating personnel to feed the bottleneck machine of cutting of giving one by one with bottle, therefore, human input amount, cutting efficiency remain unsatisfactory.

In view of this, U.S. Patent number US3886824 discloses a kind of blowing method and device of hollow plastic container, wherein go back the technology contents that emphasis has related to the overlap excision that will be retained on the hollow container, from its description that provides and accompanying drawing as can be known, the structure of cutting the overlap device is made of strip blade cuts mechanism, power revolution cutting mechanism, hollow container clamping positioning mechanism, hollow container conveying mechanism etc.Strip blade cuts mechanism comprises blade, knife rest, fixed head, guide pin bushing, guide pillar, pneumatic controller etc.; Power revolution cutting mechanism comprises frame, stepper motor, hinge wheel, chain, minor sprocket, a pair of gear wheel, bearing pin, rotating shaft, alignment pin, roller, cutting disc etc.; The hollow container detent mechanism comprises eccentric push rod, roller, arm, drive-connecting shaft, cam etc.; The hollow container conveying mechanism comprises conveyer belt etc.Specifically be to drive a pair of hinge wheel and one group of pinion rotation that is placed on the positioning and fixing arm by chain by stepper motor, one group of positioning and fixing arm is fixed on the rotary disk of swivel mount, its rotation is embodied by power transmission shaft by power, cutter axis is arranged in the centre bore of axle sleeve of each fixed arm, the upper end is fixed with pinion, the lower end is fixed by disk and cutting disc, is rotated the bottleneck overlap of the hollow container that lancinates.In order to prevent the bottleneck skew of the hollow container when cutting, clamp by a pair of positioning roller, wherein roller is fixed on an end of swing arm, the swing arm centre bore is socketed on the axle sleeve, realize clamping with the roller that is fixed on the positioning and fixing arm, the clamping force of swing arm is to guide by the cam of fixing tool chute to realize.Like this, cutting disc rotates counterclockwise cutting and drives bottleneck and turn clockwise and finish cutting.Also be provided with the strip blade cuts mechanism that guide pillar, tool rest guide pin bushing, carriage saddle, fixed head, bar blade are constituted at opposite side corresponding to bottleneck, under the promotion of cylinder, the guide pin bushing fixed head drives carriage saddle and rotates an angle together, blade is squeezed simultaneously cut bottleneck.In addition, the chain conveyor that the bottle of need excision overlap also must be special is carried.

The shortcoming of said structure is: one, can't successfully dock with the blowing bottle blowing machine, that is to say, can't be installed to or claim to be attached on the blowing bottle blowing machine, it is the cutter sweep of Dan Li; Two, complicated integral structure, it is big that difficulty is implemented in operation, because because the freedom of movement of bottleneck is big, it is many to cause destabilizing factor, easily cause the irregular waste product that forms of otch, so must could realize cutting thereby formation has three stable fulcrums (two rollers add cutting disc) by means of guide-localization roller location; Three, carry the bottle of deburring to be cut with conveyer belt, not only make package unit to occupy the space big, and can't be embodied in online excision overlap on the blowing bottle blowing machine.

Open the deficiency of clear 62-128715 at the Japan Patent spy, the spy opens the mouth overlap cutter sweep that flat JP11-114975A discloses a kind of hollow container, and its technical contribution is to ensure that distortion can not appear in the hollow container oral area, otch is attractive in appearance, complete machine is cheap.The applicant finds that it also has the following disadvantages: the one, can not constitute with the blowing bottle blowing machine, and also be a cover independent device, can not be embodied in the online cutting overlap on the blowing bottle blowing machine equally; The 2nd, be to squeeze to cut rather than rotary-cut owing to what cutting mechanism constituted, so in the bottleneck container that a fixing head will be stretched over hollow container, help the support, also to be aided with the holder clamping, otherwise can make the bottleneck distortion; The 2nd, every cutting finishes an action, and cutting arm will be made opening and closing movement one time, and so that cutting arm opening and closing and make the more complicated of guiding mechanism upper and lower, forward and backward adjustment own; The 3rd, the hollow container that adopts conveyer belt will excise overlap is fed to the cutting mechanism cutting, a whole set of cutter sweep is taken up space greatly, the 4th, complicated integral structure does not have economy, for example its also supporting Blast mechanism that blows down the overlap under being cut that is useful on.

German patent DE 2161246A discloses the technology and the device of plastic shaping hollow object, in this patented technology scheme, except introducing the blowing bottle mechanism, also introduced one and the moulding hollow object is clamped to discarded part (overlap) has separated clamping device and a separating mechanism that is used for separating discarded part near the place and one and be used for when separating discarded part the mechanism of supplying gas to hollow object blows.Its clamping device is to consist of vacuum handgrip (vacuum handgrip concrete structure does not give enlightenment) by two handgrips.The axle of separating mechanism is a hollow shaft sleeve, be located on the slide block, the fixing knife bar support arm in the lower end of hollow shaft sleeve, fixed cutting tool on the knife bar support arm, the feed of its cutter is rotated cutting after must inserting bottleneck, the displacement that withdraws from/insert is to be decided by the space between air supply pipe and the axle, in a side of slide block one cover piston apparatus is housed and controls the distance that slide block moves; The mechanism of supplying gas embodies by hollow shaft structure, and gas tube is set in hollow shaft, the air pressure in the hollow object when keeping cutting.One of shortcoming of this technical scheme, suffers from the defective that can not organically constitute a complete integral body too with the blowing bottle blowing machine, because objectively not providing it can enlighten with the technology that the blowing bottle mechanism becomes, for example discarded part separating mechanism relies on the support, and it can not be with the inside and outside template interlock of blowing bottle blowing machine; Two, the vacuum handgrip will be discarded the part excision with the action of hollow object clamping, action, separating mechanism that inflatable body is blown in hollow object action is divided into the different stages and finishes, they can not carry out synchronously with the action of blowing bottle blowing machine, and therefore, operating efficiency can't manifest; Three because the displacement that withdraws from/inserts of cutter determined by the space of air supply pipe with axle, then can undermine air supply pipe or by air supply pipe damage cutter when the displacement adjustment of cutter is improper; Four, have only continuously and in hollow object, supply gas, to guarantee the air pressure in the hollow object, could implement cutting, therefore,, thereby cause the complex structure of whole device owing to mechanism of supplying gas of existence; Five, cut quality to discarded part is difficult to guarantee, because a pair of handgrip (promptly holding bottle under the arm) is separated from one another with the discarded part separating mechanism (promptly cutting the overlap device) that is made of parts such as the slide block of tooth bar, gear, hollow shaft, axle sleeve, support arm, tool cylinder sleeve, cutters and be located on the upright in addition support, that is to say that a pair of handgrip and discarded part separating mechanism can not be synchronously and displacement equidistantly between the two.Like this, error free aligning can't be realized with the separating position on the hollow object of being seized on both sides by the arms by a pair of handgrip in the centre of gyration position of cutter, influences cut quality.So, even with the discarded part separating mechanism that this patent disclosed, a pair of handgrip is coupled on the automatic blow-molding bottle blowing machine respectively limpingly, thereby show the online cutting on the blowing bottle blowing machine in form, but because the structure that does not produce to each other between discarded part separating mechanism and the handgrip is connected, even when original design, can fully take into account the very little designing requirement of satisfying between the two of mismatch error, yet in actual use, because of the existence of blowing bottle blowing machine vibration factor can produce vibration deformation, the variation error that shows the shift position of discarded part separating mechanism can't be guaranteed corresponding with the separating position on the hollow object of handgrip clamping.The applicant finds to have only and will discard the synchronous shift that the maintenance of part separating mechanism and handgrip is followed in sb's footsteps, and the shift length error that just can make both is zero, thereby guarantees that cutter separates the disintegrate-quality of overlap at separating position.
