Description

A kind of multistation high-speed switching device of dixie cup diel

Technical field

The invention belongs to Disposable paper cup fast ram field shaping technique, the multistation particularly to a kind of dixie cup diel is high Speed switching device.

Background technology

In catering trade and daily life, huge to the consumption of Disposable paper cup, and traditional dixie cup production technology is first to roll up cup Bucket, then cup primer is stained with.This split type dixie cup, owing to needs stick with glue, so burying to the safe and sanitary of user Descended the biggest hidden danger, and this gluing method be the most not environmentally, thus a kind of stamping forming dixie cup of Novel integrated meet the tendency and Raw, this dixie cup not only has the function of traditional dixie cup, it is also possible to is used for holding the fruit jam of fast food, butter, tomato sauce etc. and adjusts Material, in order to replace the plastic sealing pack of its original.Obviously, this mode more meets the requirement of environmental protection and sustainable development, but this Dixie cup in actual production, there is also problems, as unstable in molding, easily scatter, percent defective is high, production efficiency is low.

Number of patent application be 201520099992.8 Chinese utility model patent disclose the cup mould that a kind of yield rate is high, including Top cover, heating rod, elastomeric element, mold inner sleeve, embossing mold, crimping upper mold core, embossing lower mold add heat pipe, volume Limit lower mold, crimping lower mold inner sleeve, punch components, auxiliary section etc., it is a kind of one-time formed composite die of single-station, But in Practical Project production practices, find that the punch forming dixie cup finished form that this single-station composite die produces is soft, time long Between place after easily scatter；Thus, a kind of multistation dixie cup impact molding machine is occurred in that on the market, between this kind of each station of device Switching uses the version of the purely mechanic transmission such as cam, connecting rod, and this structure is to the precision of motion parts, intensity, motion The requirement of position wearability and assembling is high, and the precision of no person's machine is difficult to keep, and can lose precision after long time running, actual Job insecurity in production；Number of patent application be 200810121604.6 Chinese invention patent disclose a kind of paper cup making machine, including Cup bucket shaping mechanism, indexing rotary table, heating station, folding basic skill or training position, rolling basic skill or training position, circle mouth station, each station part is by indexing Turntable rotation switches, owing to the kinetic characteristic of indexing rotary table is limited by motor performance so that the switch speed between each station is limited, And the station of its molding is the most more, this just greatly limit its production efficiency；Meanwhile, the structure of this indexing disc type is near dividing At the periphery of scale, rigidity is the most not enough, vibrates bigger during high-speed motion.Therefore, a simple in construction, efficiency height, work are designed The multistation high-speed switching device making stable Disposable paper cup diel is the most necessary.

Summary of the invention

It is an object of the invention to for the deficiencies in the prior art, it is provided that the multistation high-speed switching device of a kind of dixie cup diel, The structure brought when utilizing cam link mechanism and index dial switching station with solution prior art is the most complicated, and speed is slow, effect The defects such as rate is low, poor rigidity.

The technical problem to be solved realizes by the following technical solutions.

A kind of high-speed multi-station dixie cup punch forming device, including base, lower bolster, upper mold moves plate, upper mold determines plate, upper and lower mould Group and linear motion system, it is characterised in that: it is connected by screw between described lower bolster and each guide rail slide block；Described lower bolster Connect with being connected seat also by screw；Two alignment pins joining work it are provided with between described connection seat and lower bolster, and on lower bolster It is additionally provided with positioning step；Described left and right upper mold is moved on plate each equipped with four guide pillars, and by guide pillar briquetting and screw be fixed on its four Angle；The sliding bearing that described guide pillar is determined on plate with upper mold coordinates；Described sliding bearing coordinates location with cope match-plate pattern by interior exit orifice, It is screwed connection；Described upper mold is moved plate and is connected with being contained in the cylinder rod end that upper mold determines on plate also by nut；Described lower bolster Both sides are provided with receipts cup cylinder and receive cup bucket.Wherein, receive cup cylinder and be fixed by screws on lower bolster, receive cup bucket and pacified by nut It is contained in receipts cup cylinder rod end.

Described linear motion system includes servomotor, decelerator, motor mount, positive coupling, ball-screw, straight line Guide rail, feed screw nut, taper roll bearing.Wherein, described servomotor connects decelerator and is arranged on motor mount, and leads to Crossing positive coupling to be connected with ball-screw, ball-screw two ends are respectively by being arranged in motor mount and leading screw mounting seat The taper roll bearing that a pair is installed face-to-face is fixed；Described feed screw nut is with the connection seat being arranged under lower bolster by nut even Connect, nut leaves oil filler point, be used for lubricating；Described line slideway is installed in the positioning step of submounts, leads at straight line Trackside face is provided with equally spaced wedge shape compact heap, and is fixed in submounts at linear guide rail end surface with equally spaced screw.

Described upper and lower module include a upper left mould, No. two upper left moulds, No. three upper left moulds, upper right mould, No. two upper right moulds, No. three upper right moulds, lower-left mould, No. two lower-left moulds, No. three lower-left moulds, bottom right mould, No. two bottom right moulds, No. three bottom rights Mould.Wherein, described left and right mode structure is full symmetric, and each mould is connected with each installing plate by the hole, location on installing plate and screw； It is equipped with negative pressure in described mold and inhales paper air flue, and communicate with air-channel system by being arranged on the adapter of mould side；

All there is pump nozzle on described feed screw nut and straight-line guide rail slide block, and be connected with lubricant passage way, the regular oiling of oil pump carry out Lubrication.
