The utility model discloses a kind of longitudinal tensile fixtures of heat shrink films, belong to heat shrink films production equipment technology, entrance jockey pulley, pre-stretching device, heating device, stretching device, cooling device, outlet jockey pulley including sequence setting, the heating device and stretching device sequence setting several groups, the tensile performance in wale-wise of heat shrink films can be improved, play the tensile performance in wale-wise of heat shrink films to greatest extent.
Description
Technical field
The utility model belongs to heat shrink films production equipment technology, the longitudinal stretching dress of specifically a kind of heat shrink films
It sets.
Background technology
Heat shrink films refer to the plastic film with certain contractility when heating at a predetermined temperature.The prior art is in life
It is mainly prepared by vertical or horizontal drawing process when heat production shrink film.Film after inflation film manufacturing machine film extrusion, then
The secondary length being stretched to film by preheating mechanism, drawing mechanism and cooling body using required shrinking percentage.But it is existing
This production technology is post forming in production process, cannot effectively utilize the shrink characteristics of resin, and low production efficiency is raw
It produces of high cost.
Utility model content
In view of the above-mentioned problems, in order to more preferably utilize the characteristic of resin.The utility model devises a kind of heat shrink films life
The longitudinal tensile fixture for producing equipment carries out the longitudinal stretching of film with inflation film manufacturing machine on-line synchronous, once produces heat shrink films.
A kind of longitudinal tensile fixture for heat shrink films that the utility model embodiment provides includes the entrance of sequence setting
Power roller, pre-stretching device, heating device, stretching device, cooling device, outlet jockey pulley, the heating device and stretching device
Sequence setting several groups.
The pre-stretching device includes pre-stretching roller, pre-stretching heating, cooling device and pre-stretching roll-in roller.
The heating device includes heating roller, heating system.
The stretching device includes draw roll, draw roll heating, cooling system, draw roll pressure roller.
The cooling device includes chill roll, chill roll cooling system, chill roll pressure roller.
Preferably, the entrance jockey pulley, pre-stretching device, heating device, stretching device, cooling device, outlet tension
The quantity of roller is 1,1,2,2,1,1.
When utility model works, each roller is independently driven to operate by motor, the diaphragm blown by inflation film manufacturing machine continuous production
First by entrance jockey pulley, one-off drawing is carried out using pre-stretching device, pre-stretching device includes pre-stretching roller, pre-stretching
Heating, cooling device and pre-stretching roll-in roller, pre-stretching, which is heated, cooling device provides for pre-stretching device can automatically adjust temperature
Heat source, the diaphragm after one-off drawing sequentially passes through heating device, stretching device again, diaphragm after stretching certain length again,
Sequence carries out multi-drawing by heating device, stretching device, cycle again, until the heat shrink films performance indicator for reaching design is wanted
It after asking, then is cooled down by cooling device, most enters finished product process through exporting jockey pulley afterwards.
The beneficial effects of the invention are as follows：Adjust automatically and the tensile performance in wale-wise indexs of heat shrink films can be improved, it is maximum
The tensile performance in wale-wise feature of the performance heat shrink films of limit.

Further, heating system 32 is heater box.
When utility model works, each roller is independently driven to operate by motor, the diaphragm blown by inflation film manufacturing machine continuous production
First by entrance jockey pulley 1, one-off drawing is carried out using pre-stretching device 2, pre-stretching device 2 include pre-stretching roller 21,
Pre-stretching heating, cooling device 22 and pre-stretching roll-in roller 23, pre-stretching heating, cooling device 22 are that pre-stretching device 2 provides
The heat source of temperature can be automatically adjusted, the diaphragm after one-off drawing sequentially passes through heating device 3, stretching device 4 again, and diaphragm is through again
After stretching certain length, then sequence, by heating device 3, stretching device 4, cycle carries out multi-drawing, until reaching design
After heat shrink films performance indicator requires, then by cooling device cooling 5, most enter finished product process through exporting jockey pulley 6 afterwards.
Be described in above-described embodiment illustrate this patent, though text in illustrated by specific term, not
The protection domain that this patent can be limited with this, be familiar with this technical field personage can understand this patent spirit with it is right after principle
It, which changes or changes, reaches equivalent purpose, and this equivalent change and modification, should all be covered by right and be defined
In scope.
