Abstract
The utility model discloses a kind of default pulling force discharging structure for preventing film from squeezing out fold, including the side bottom in bosh is arranged in extrusion die, the extruder head of extrusion die；Isolation board is set in the middle part of bosh, and isolation board setting passes through a pair of of nip rolls of setting above slot by slot；The side of bosh above isolation board is symmetrical arranged water outlet and discharge outlet, the water outlet connect circulating pump between discharge outlet by pipeline；The water inlet front end is arranged effluent trough, the effluent trough between bosh side wall at a distance from it is adjustable.The utility model has the advantages that：And the variation of motor speed can cause the variation of water velocity, and then the pressure of film is adjusted, pulling force when final influence is wound.
Description
Technical field
The utility model is related to machinery field, cooling structure when specifically a kind of film squeezes out.
Background technology
When plastic film produces, need to be prepared into film by extruder after heating polypropylene, the prior art is general
The extrusion of extruder is arranged in bosh, the film of extrusion after water cooling by being directly wound on material roller；Due to rigid
The film temperature of extrusion is high, and therefore, film can not bear pulling force, is folded frequent occurrence when roller is expected in winding, waste material is caused to increase.
Utility model content
In order to solve the above technical problems, certain the object of the present invention is to provide having when thinfilms material roller can be improved in one kind
Pulling force, the cooling structure that will not be folded, specific technical solution are as follows：
A kind of default pulling force discharging structure for preventing film from squeezing out fold, including extrusion die, the extruder head setting of extrusion die
In the side bottom of bosh；Isolation board is set in the middle part of bosh, and isolation board setting passes through setting one above slot by slot
To nip rolls；The side of bosh above isolation board is symmetrical arranged water outlet and discharge outlet, the position of water outlet and discharge outlet
The both sides of film are separately positioned on, the water outlet connects circulating pump between discharge outlet by pipeline；The water outlet setting exists
On one sector, each faucet is also sector, and discharge outlet is arranged at the both ends of film；The cooling water of cycle is in pellicular front
It is upper to form uniform pressure, the fold of film is smoothed using the pressure.
The circulating pump has servo motor drive, servo motor to be connect with control cabinet, can set motor by control cabinet
Rotating speed.The circulating pump has servo motor drive, servo motor to be connect with control cabinet, can set servo motor by control cabinet
Rotating speed.
Film force area is adjusted using the adjustment up and down of isolation board.
The utility model has the advantages that：Due to squeeze out when the above position of isolation board the second cooling space, water inlet and
The setting for following discharge outlet forms certain slowly flowing water stream so that pellicular front bears certain hydraulic pressure, therefore, in material roller rolling
When dynamic, film bears certain pulling force, will not cause the folding of film.And the variation of motor speed can cause the change of water velocity
Change, and then the pressure of default film, pulling force when final influence is wound, to avoid the generation of fold.
Description of the drawings
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is the position view of water outlet and discharge outlet.
Specific implementation mode
The present invention is illustrated below in conjunction with the accompanying drawings, and as shown in Figure 1 and Figure 2, the present invention includes extrusion die 1, extrusion die
Extruder head 2 side bottom in bosh 3 is set；Isolation board 4 is set in the middle part of bosh, isolation board setting passes through slot 5,
Pass through setting a pair of nip rolls 6 above slot；The side of bosh above isolation board is symmetrical arranged water outlet 7 and discharge outlet 8, institute
It states and circulating pump is connected by pipeline between water outlet and discharge outlet；The water inlet front end is arranged effluent trough 9, the effluent trough 9 with
Distance between bosh side wall is adjustable.In figure, 10 be liquid level, and 11 be film, and 12 be material roller.
As shown in Fig. 2, the position of water outlet 7 and discharge outlet 8 is separately positioned on the both sides of film, the water outlet setting exists
On one sector, each faucet 91 is also sector, and discharge outlet is arranged at the both ends of film；The purpose being arranged in this way be for
Uniform pressure is formed on pellicular front, and ensures the flow direction of the water outlet arrow direction along figure, utilizes the pressure of flowing water
Power smooths the fold of film.
The principles of the present invention are：
Since the position and shape setting, recirculated water of water inlet and discharge outlet form certain slowly flowing water stream, make
It obtains pellicular front and bears certain hydraulic pressure, and hydraulically-formed power is directed towards the both sides of film, folding can be generated to avoid film；
When expecting that roller rolls, film bears certain pulling force, will not cause the folding of film；And the variation of the servo motor rotating speed of circulating pump
It can cause the variation of water velocity, and then adjust the pressure of film, the final pulling force for influencing to be subject to when thinfilms.
Isolation board can adjust up and down；The adjustment up and down of isolation board is to realize the adjustment for the area that exerts a force to film, ensure
The uniform stressed of film.The structure of adjustment up and down of isolation board can be that the bolt that rises, the bolt abutting that rises is arranged in the outside of isolation board
On the inside wall of sink；It can also be the holder etc. that adjustment height is set below isolation board.
