Description
Technical field
It the utility model is related to synthetic leather production equipment technology, more particularly to a kind of dry method active unwinding tension
Control system.
Background technology
Synthetic leather dry process attaching process with base fabric will be bonded coated in the resin bed in release liners produces conjunction
Finished leather, in synthetic leather dry process production line, unreeling for base fabric is a highly important process.And the excessive or mistake of unwinding tension
The small quality and production efficiency that will directly affect product quality；Unwinding tension control has a variety of methods, just because of tension force
Complexity, the diversity of control, therefore one Analysis of Nested Design of selection is reasonable, dependable performance, tension force easy to maintain, economical rationality
System is particularly important.
At present, the torsion of the whole magnetic powder cluth of tension force instrument control system or magnetic powder brake is commonly used in synthetic leather dry process production line
Square, so as to obtain required tension force.During unreeling, constantly reduce with the coil diameter for unreeling product, operating personnel just must
It by virtue of experience must at any time check and unreel product tension force, adjust output torque at any time, to keep tension stability.But unreeled in stretch fabric
When, since stretch fabric has larger elastic and easily occurs that tension force is unstable, contracting phenomenon, original tension control system is not
It can meet production requirement.
Utility model content
The utility model is precisely in order to avoid the shortcoming present in the above-mentioned prior art, there is provided a kind of dry method active release
Roll tension control system.
The utility model adopts the following technical scheme that to solve technical problem：
A kind of dry method active release roll tension control system, including be arranged the spool of base fabric, and be staggered in spool and
Upper guide roller and lower steering roll between doubling roller, the both ends of the lower steering roll are separately installed with tension sensor, described
The output terminal of force snesor passes sequentially through tension controller, frequency converter and variable-frequency motor and connects, the output shaft of the variable-frequency motor
It is connected with spool.
Further scheme, is attached between the tension controller and tension sensor using shielding line.
Further scheme, the tension sensor are installed on the both ends of lower steering roll by bearing block.
Tension controller, frequency converter and variable-frequency motor etc. are commercial products in the present apparatus, are not related to tension controller
Internal structure and operation principle, tension controller such as Siemens EM235.The utility model is applied them to active release
In roll tension control system.
Base fabric is sleeved on spool, the tension value for unreeling needs is first set on tension controller.During formal production, wait to paste
After closing under roll-in, the run switch of tension controller is opened, the tension sensor installed in lower steering roll both ends is examined at any time at this time
Its tension signal is surveyed, and feeds back to tension controller, it compared with the tension value set, then will by tension controller
Transfer rate and torque command issue frequency converter, so as to control rotating speed and the torque of variable-frequency motor, realize and unreeling for spool is opened
The stability contorting of power, so as to meet production requirement.
The unwinding tension signal that tension sensor detects is passed to the closed loop of tension controller composition by the utility model
Control system, rotating speed and torque by Frequency Converter Control variable-frequency motor, realizes the stability contorting to its tension force.In addition, this reality
Set and operated with novel digital type, simple and convenient, tension force stability is high, can effectively meet production requirement.
Brief description of the drawings
Fig. 1 sheets are the structure diagram of utility model.
Embodiment
Elaborate below to the embodiment of the utility model, the present embodiment using technical solutions of the utility model before
Put and implemented, give detailed embodiment and specific operating process, but the scope of protection of the utility model is unlimited
In following embodiments.
Referring to Fig. 1, a kind of dry method active release roll tension control system, including the spool 8 of base fabric 9 is arranged, and staggeredly set
Upper guide roller 10 and the lower steering roll 4 between spool 8 and doubling roller 1 are put, the both ends of the lower steering roll 4, which are separately installed with, opens
Force snesor 2, the output terminal of the tension sensor 2 passes sequentially through tension controller 5, frequency converter 6 is connected with variable-frequency motor 7,
The output shaft of the variable-frequency motor 7 is connected with spool 8.
Further scheme, is attached between the tension controller 5 and tension sensor 2 using shielding line.
Further scheme, the tension sensor 2 are separately mounted to the both ends of lower steering roll 4 by bearing block 3.
Base fabric 9 is sleeved on spool 8, the tension value for unreeling needs is first set on tension controller 5.During formal production,
After roller 1 to be fit is depressed, the run switch of tension controller 5 is opened, at this time installed in the tension sensor at 4 both ends of lower steering roll
2 detect its tension signal at any time, and feed back to tension controller 5, and tension controller 5 is compared it with the tension value set
Compared with transfer rate and torque command then are issued frequency converter 6, so as to control rotating speed and the torque of variable-frequency motor 7, realized to volume
The stability contorting of the unwinding tension of axis 8, so as to meet production requirement.
The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all in this practicality
All any modification, equivalent and improvement made within new spirit and principle etc., should be included in the guarantor of the utility model
Within the scope of shield.
