Detailed Description
The utility model provides a tension control device for grinding rolling of nylon base cloth. The technical solution of the present invention will be described in detail below with reference to the accompanying drawings so as to be easier to understand and grasp.
A tension control device for grinding nylon base cloth rolling, as shown in figure 1, comprises a feeding mechanism 1 and a rolling mechanism 2, and a tension control mechanism 3 is arranged between the feeding mechanism 1 and the rolling mechanism 2.
The feeding mechanism 1 includes a driving feed roller 11 and a driven feed roller 12 which are vertically arranged, and a driving feed roller driving source 13 for driving the driving feed roller 11 to rotate, and the driven feed roller 12 has a lifting displacement.
The winding mechanism 2 includes a winding roller 21 and a frequency-modulated drive source 22 with a rotational speed adjustment for driving the winding roller to rotate.
The tension control mechanism 3 comprises a friction roller 31 for supporting the material belt and a tension control sensor 32 matched with the friction roller 31, wherein the tension control sensor 32 is connected with the frequency modulation driving source 22 in a communication mode.
The specific implementation process and principle description are as follows:
the material belt formed by the sand planting process passes through a feeding gap between the driving feeding roller 11 and the driven feeding roller 12 and then is connected to the wind-up roller 21 through the friction roller 31.
Under the self-weight state of the material belt, a large friction force is generated between the material belt and the friction roller 31, namely, the surface of the friction roller 31 is provided with a matching material such as rubber and the like for increasing the matching friction force, a certain traction force is generated on the material belt in the winding process of the winding roller 21, the traction force is transmitted to the tension control sensor 32 through the friction roller 31, and the tension control sensor 32 can monitor the traction force to control the frequency modulation rotating speed of the frequency modulation driving source 22, so that the stable action of maintaining the traction force is realized. Under the traction force steady state, the tension of the rolled material belt is steady, the winding is uniform and compact, and the phenomena of overlarge tension deformation and undersize tension relaxation can not occur.
The frequency modulated communication between the tension control sensor 32 and the deployment drive source 22 is well known in the art and will not be described further herein.
It should be noted that, in the present case, the feeding clearance can be adjusted through the lift displacement of driven feed roll 12, satisfies the material area pay-off demand of different thickness. When the material belts with different thicknesses are wound on the winding roller 21, the traction force is difficult to guarantee along with the relation between the diameter change of the wound material and the rotating speed, so that the traction force real-time regulation and control of the material belts with different thicknesses can be met by adopting a mode of combining the tension control sensor 32 and the allocation rotating speed, and the stability of the winding tension is ensured.
In one particular embodiment, the take-up roll 21 rotates in a direction opposite to the direction of rotation of the active feed roll 11.
Specifically, in order to meet the requirement that the friction roller 31 is attached to the tape, the tape diameter of the wind-up roller 21 needs to be changed sufficiently, and if the wind-up roller 21 rotates in the same direction as the active feed roller 11, the height of the wind-up roller 21 needs to be low enough to ensure that the tape at the wind-up end thereof can fall on the friction roller 31.
However, the abrasive belt itself has a larger thickness, the radius of the wound coil material is larger, and the winding end of the abrasive belt is higher and higher along with the increase of the radius of the material belt, which is not favorable for matching with the friction roller 31.
Therefore, the design that the direction of rotation of wind-up roll 21 and the opposite direction of rotation of initiative feed roll 11 have been adopted to the present case, and along with the receipts material of wind-up roll 21 is more and more promptly, its rolling end can be lower and lower more, consequently can ensure that the material area is laminated mutually with friction roller 31, in addition, wind-up roll 21 material loading area from the bottom is upwards coiled, can also maintain certain tension with the help of the material area dead weight, reduces tension control sensor 32's tension control load for the material area coiling is comparatively tight.

Specifically speaking, the lifting stroke control of the lifting adjusting rod 5 meets the requirement for height adjustment of the bearing seat, so that the adjustment of the fit clearance is realized, and the feeding requirement of material belts with different thicknesses is met.
In one embodiment, the driving roller driving source 13 is a driving motor, and the driving motor is connected with the driving roller in a chain belt transmission manner. The frequency modulation driving source 22 is a frequency modulation motor, and the frequency modulation motor is connected with the wind-up roll in a chain belt transmission manner.
Specifically, the chain belt is connected in a transmission mode, namely the chain belt is connected with the gear disc in a matched mode, the toothed belt or the synchronous belt is adopted in the traditional operation mode, the toothed belt and the synchronous belt are made of elastic materials and are easy to age and have ductility, transmission torque loss and even breakage are caused, the chain belt transmission mode can reduce torque loss, operation precision and stability are improved, and the service life is long.
In one embodiment, a tape counting mechanism 6 is disposed between the tension control mechanism 3 and the winding mechanism 2, and the tape counting mechanism includes a follower roller 61 and a meter-counting wheel 62 for cooperating with the follower roller to clamp the tape. The metering wheel has an elastic pivot displacement against which the follower roller abuts.
