Description
Technical field
The utility model is related to technical field of mechanical processing, especially a kind of plastic sheet is with printing film without the laminating dress of glue
It sets.
Background technology
Plastic sheet refers to the plastic uptake sheet material for being applied to use in plastic thermoforming product, and thickness is usually 0.18-2mm；
Material includes the sheet material that the Packing Machines such as PP, PS, PET can be produced, be made.The sheet material be mainly used in make cup, fresh fruit pallet,
The plastic products such as sushi pallet.Currently, making the sheet material of the products such as cup, fruit tray, sushi pallet using thermoforming, mostly
Using the sheet material for the solid color that plastics material grain and color masterbatch are formed by heating, extrusion, press polish, this based sheet only has single
Color, aesthetics are insufficient.In current thermoformed article production process, it is thin typically to unify kind of printing in plastic sheet overlying
Film carries out heating, drying after a face coated with adhesive of printing film, then is coated with the printing film heat of adhesive side
Conjunction is covered to plastic sheet.This process that laminating printing film is carried out using adhesive, complicated, step is relatively more,
Adhesive easy tos produce bubble, causes laminating ineffective, and the clast for be easy to causeing adhesive is sticked to plastic sheet edge, is not easy
Remove, and tend to have residue glue when cut plastic sheet and be attached in equipment, the residue glue on eliminating equipment is pretty troublesome, in addition purchase with
It also needs to expend an expense when producing adhesive, the production cost is very high.
Invention content
The technical problem to be solved by the present invention is to provide a kind of plastic sheet and printing films without glue lamination device, this
Kind without glue lamination device without be added adhesive can be realized as it is laminating between plastic sheet and printing film so that after laminating
Plastic sheet will not be with toughness clast, residue glue, laminating effect is more preferable, and structure is simpler, is more energy-saving and environmentally friendly, is produced into
This reduction.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is as follows：
A kind of plastic sheet is unreeled with printing film without glue lamination device, including rack, sheet extruder structure, printing film
Mechanism, coating mechanism and rolling-up mechanism, sheet extruder structure, printing film unreeling structure, coating mechanism and rolling-up mechanism difference
In rack, sheet extruder structure and brush thin-film unreeling mechanism are located at the front of coating mechanism, and rolling-up mechanism is located at laminating
The rear of mechanism, it is characterized in that：The extrusion die of the sheet extruder structure is close to the coating mechanism；The printing film is put
Volume mechanism includes unreeling shaft, floating shelf, the first intersection deflector roll, the second intersection deflector roll and spreader roll；Unreeling shaft, first, which are intersected, leads
Roller, spreader roll are sequentially arranged in the rack；Floating shelf is movably arranged in rack, and second, which intersects deflector roll, is mounted on floating shelf
On, second, which intersects deflector roll, is between the first intersection deflector roll and spreader roll.
In above structure, unreeling shaft, the first intersection deflector roll, the second intersection deflector roll, spreader roll are arranged in order, printing film from
Unreeling shaft is released, and intersects deflector roll by first, the second importing for intersecting deflector roll and spreader roll conveys, it is ensured that printing film is smoothly defeated
It is sent on coating mechanism, printing film can be flattened and be stretched, it is ensured that laminating quality avoids generating fold when laminating.The
Two intersection deflector rolls can float up and down under the action of floating shelf, so that printing film is kept suitable tension, printing film is flattened
It stretches.At coating mechanism, since the extrusion die of sheet extruder structure is close to coating mechanism, the residual temperature of freshly extruded sheet material is utilized
Carry out it is laminating, without be added adhesive can be realized as it is laminating between plastic sheet and printing film so that the modeling after laminating
Media sheet will not be with toughness clast, residue glue, and avoids generating bubble, and laminating effect is more preferable, and structure is simpler, more energy saving
Environmental protection, production cost reduce.
As the preferred embodiment of the utility model, described first intersects deflector roll, the second intersection deflector roll includes roll body, and
The forward screw thread section and reverse thread section being arranged on roll body outer surface, forward screw thread section, reverse thread section are with roll body central point
It is symmetrical.Forward screw thread section, reverse thread section are set on roll body outer surface, and first intersects deflector roll, the second intersection deflector roll is turning
When dynamic so that both screw threads extend from the middle to both ends respectively, and then make to intersect deflector roll with first, second intersect deflector roll and connect
Tactile printing film surface is flattened from centre to both sides, and first intersects deflector roll, the second intersection deflector roll and printing film surface whole
Contact, printing film surface are more uniformly stressed, and the surface tangent after printing film expansion is approximately straight line, subsequently again will
When the printing film is laminating with other sheet materials, bulging wrinkling will not occur, play and eliminate in printing film transmission process
Fold, meet the requirement of laminating product.Moreover, after intersecting deflector roll using the first intersection deflector roll, second, the first intersection is led
Roller, the second intersection deflector roll are all contacted with printing film surface, and printing film will not improve in transmission process to both sides play
The end face quality of printing film.
As the preferred embodiment of the utility model, the roll body cross-sectional area of the spreader roll gradually subtracts from intermediate toward both ends
It is small.By this set, there is arc convex in the middle part of spreader roll, to be handed over the second of top in printing film transmission process
Fork deflector roll matches, and by printing film along the both ends spread apart of spreader roll, ensures printing film uniform force, prevents from printing thin
Film generates fold in transmission process.

Gap.This laminating mode breaches the normal mode for traditionally using adhesive laminating, utilizes a dough sheet in double-layer plastic sheet material
Material has heat sealability, and double-layer plastic sheet material, the residual temperature on freshly extruded double-layer plastic sheet material are squeezed out by sheet extruder structure
Printing film can be allowed fully to be adhered in double-layer plastic sheet surface so that freshly extruded double-layer plastic sheet material can be not cold
But before and printing film progress is directly laminating, can be good at control printing film and is adhered to freshly extruded double-layer plastic sheet material
On.Since freshly extruded double-layer plastic sheet temperature is higher, and surface-active is far above the table that double-layer plastic sheet material is heated
Face activity, when laminating, this facesheet of EVA, LDPE material and printing film interpenetrate, and form fine and close adhesive layer so that
Combination between this facesheet of EVA, LDPE material and printing film is closer, more closer than glue bonding, it need not be added
Any adhesive and solvent, without processes such as coating adhesive and drying, laminating effect is more preferable, and structure is simpler, more supernumerary segment
It can environmental protection.
