A kind of tension structure of batcher, as shown in Figure 1, including watching for rack 1, support roller 2 and the driving rotation of support roller 2
Take motor 3.Support roller 2 has two and is parallel to each other, and two support rollers 2 are rotationally connected in rack 1.It is coaxial in support roller 2
It is fixedly connected with belt pulley 21, servo motor 3 is fixedly connected on 1 row of rack and drives 2 constant speed of support roller same by V belt translation
To rotation.Cloth rewinder roll 6 is placed between two support rollers 2 and supports cloth rewinder roll 6 using support roller 2, and servo motor 3 drives support roller
2 rotations, rotation is under the action of frictional force to wind cloth on cloth rewinder roll 6.
As shown in Fig. 2, rack 1 is rotatably connected to connecting rod 511, the both ends of connecting rod 511 are fixedly connected to pivoted arm 51,
The middle position of pivoted arm 51 is rotatably connected to idler roller 5, and pivoted arm 51 is connected with spring 52, spring far from one end of connecting rod 511
52 other ends are connect with rack 1.Cloth enters tension structure on the right side of rack 1, then from the lower section of idler roller 5 around to rack 1
Upper right side, drive cloth rewinder roll 6 to rotate counterclockwise and wind cloth using support roller 2.Pivoted arm 51 is produced using the elastic force of spring 52
The raw trend deflected counterclockwise tenses cloth so that idler roller 5 be contacted on cloth.
As shown in Fig. 2, be fixedly connected with fixed link 53 in rack 1, when cloth tension is excessive, cloth draw it is very tight when, turn
Arm 51 is rotated clockwise and is contacted in fixed link 53, and 52 elongation of spring is less than maximum flexibility deformation quantity at this time, thus sharp
It prevents 51 rotational angle of pivoted arm excessive with fixed link 53 and causes spring 52 that plastic deformation occurs, protect spring 52.
As shown in Fig. 2, the right end of pivoted arm 51 has been fixedly and coaxially connected transmission gear 512, transmission gear 512 is sector
Wheel.The angular transducer 4 for detecting 51 deflection angle of pivoted arm is fixedly connected in rack 1.It is coaxially fixed on angular transducer 4
It is connected with the connection gear 41 engaged with transmission gear 512, the reference diameter of connection gear 41 is less than point of transmission gear 512
Spend circular diameter.The transmission ratio of pivoted arm 51 and angular transducer 4 is increased using connection gear 41 and transmission gear 512, to make
The rotational angle of the more accurate detection pivoted arm 51 of angular transducer 4.Angular transducer 4 is electrically connected with the controller, and utilizes angle
Sensor 4 detects the rotational angle of pivoted arm 51 to judge that the tensioning degree of cloth at this time utilizes controller when overtension
The revolving speed of servo motor 3 is reduced, tension is reduced；When tension is too small, increase the revolving speed of servo motor 3 using controller, increases
Tension makes to wind better effect to achieve the purpose that cloth tension is constant when winding cloth.
As shown in figure 3, being fixedly connected on pivoted arm 51 to reduce the frictional force between idler roller 5 and pivoted arm 51
Determine bearing block 54,5 both ends of idler roller are placed through in fixed bearing block 54, and the two is rotatablely connected.Spring 52 is far from idler roller 5
One end be connected with pull rod 521.521 one end of pull rod is fixedly connected with pull ring 522, and spring 52 and pull ring 522 are linked up with.Pull rod 521
Threaded one end far from pull ring 522 is connected with adjusting nut 524.Fixing seat 523,521 one end of pull rod are fixedly connected in rack 1
It is placed through in fixing seat 523 and the two is slidably connected, adjusting nut 524 contacts at side of the fixing seat 523 far from pivoted arm 51
To provide the pulling force for overcoming 52 elastic force of spring for pull rod 521.Rotate adjusting nut 524, the tension journey of adjustable spring 52
Degree, to adjust the tensioning degree of cloth.
As shown in figure 4, being equipped with connection bolt 513 on pivoted arm 51, it is threaded with and is fixed on connection bolt 513
The first nut 514 on pivoted arm 51, connects and is threaded with the second nut 515 on bolt 513, and 52 one end of spring is linked up in connection
On bolt 513 and between the first nut 514 and the second nut 515.It is limited using the first nut 514 and the second nut 515
The position for determining spring 52 prevents tension structure from spring 52 being made to fall off during regulating tension of fabric from connection bolt 513, makes
Connection structure between spring 52 and pivoted arm 51 is more stable.
Specific working mode: servo motor 3 drives two constant velocity rotations clockwise of support roller 2 by V belt translation, makes cloth rewinder roll 6
It rotates counterclockwise, cloth is wound.When cloth tenses, 5 stress of idler roller is to make pivoted arm 51 rotate clockwise while make bullet
Spring 52 elongates.When pivoted arm 51 rotates, band nutating gear 512 is rotated, and transmission gear 512 drives connection gear 41 to rotate, thus
The deflection angle of the detection pivoted arm 51 of angular transducer 4.Then servo motor 3 is controlled using controller, makes the rotation speed of support roller 2
Degree slows down, so that the rolling speed of the cloth slowed down, reduces the tension of cloth.When cloth relaxation, 5 stress of idler roller subtracts
It is small, it is rotated counterclockwise under the action of 52 elastic force of spring, to detect the deflection angle of pivoted arm 51 using angular transducer 4, so
Servo motor 3 is controlled using controller afterwards, accelerates the velocity of rotation of support roller 2, the tension of cloth is increased, to reach
Cloth tension constant purpose when winding cloth makes to wind better effect.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
