A kind of tensioning apparatus of forming machine, as shown in Figure 1, including rack 1, wind-up roll 2, let off roll 3, tensioning detection device
5 and brake gear 6.Wind-up roll 2 and let off roll 3 are located at the both ends of rack 1, and wind-up roll 2 and the let off roll 3 company of rotation
It is connected in rack 1.The driving motor 4 that driving wind-up roll 2 rotates is fixedly connected in rack 1, it is in need fixed to wind on let off roll 3
The fabric of type, fabric get off from debatching on let off roll 3 and wind on wind-up roll 2, and driving motor 4 drives wind-up roll 2 to rotate
When, fabric is wound in wind-up roll 2, and the effect of the pulling force of fabric is got off to from debatching on let off roll 3.It is tensioned detection device
5 are located at the middle position of rack 1, the size of the tensile force for detecting fabric.Brake gear 6 is located at rack 1 close to let off roll 3
One end.When the tensile force of fabric reduces, slow down the debatching speed of let off roll 3 using brake gear 6, and wind-up roll 2 at this time
Velocity of rotation it is constant, and then be tightened up fabric, increase the tensile force of fabric；When the tensile force of fabric increases, reduces and stop
Limitation of the vehicle device 6 to the debatching speed of let off roll 3, and the velocity of rotation of wind-up roll 2 is constant at this time, and then reduces of fabric
Clamp force.
As shown in Fig. 2, 3 both ends of let off roll have been fixedly and coaxially connected brake disc 31.Brake gear 6 include fixed frame 61,
Brake block 63 and hydraulic cylinder 62, fixed frame 61 are fixedly connected in rack 1, and fixed frame 61 is in using 3 pivot center of let off roll as the center of circle
Arc, fixed frame 61 offers the groove 611 of arc, and 63 edge of brake block is located in groove 611.Hydraulic cylinder 62 is fixedly connected
On the outer wall for having fixed frame 61, the cylinder body of hydraulic cylinder 62 is fixedly connected on fixed frame 61, and the push rod of hydraulic cylinder 62, which passes through, to be fixed
Frame 61 extends in groove 611.Brake block 63 is located in groove 611 and is fixedly connected on the push rod of hydraulic cylinder 62.Face to face
When the tensile force of material is too small, it is mobile to brake block 63 that hydraulic cylinder 62 pushes push rod, thus increase brake block 63 and brake disc 31 it
Between frictional force, slow down the debatching speed of let off roll 3, and the velocity of rotation of wind-up roll 2 is constant at this time, and then draws fabric
Tightly, increase the tensile force of fabric；When the tensile force of fabric is excessive, the pulling push rod of hydraulic cylinder 62 direction separate to brake block 63
It is mobile, to reduce the frictional force between brake block 63 and brake disc 31, accelerate the debatching speed of let off roll 3, and wind at this time
The velocity of rotation of roller 2 is constant, and then reduces the tensile force of cloth, to achieve the purpose that adjust fabric tensioning.
As shown in figure 3, tensioning detection device 5 includes guide rod 53, sliding block 51, idler roller 52 and piston cylinder 55, guide rod 53 has
Four are fixedly connected on 1 two sides of rack vertically respectively, and 1 two sides of rack are fixedly connected to two parallel guide rods 53.Sliding block 51
Also it is sheathed on there are two and respectively on the guide rod 53 of 1 two sides of rack, is in be slidably connected between sliding block 51 and guide rod 53.Idler roller
52 both ends are rotated in respectively on sliding block 51, and idler roller 52 is located at the top position of fabric, and idler roller 52 supports under gravity
It touches in the upper surface of fabric.When the tensile force of fabric increases, fabric applies thrust to idler roller 52 and moves it up；Face to face
When the tensile force of material reduces, fabric applies thrust to idler roller 52 and reduces, so that idler roller 52 moves down under the effect of gravity.
As shown in figure 3, being fixedly connected with piston cylinder 55 in rack 1, piston 56, piston 56 are slidably connected in piston cylinder 55
It is fixedly and coaxially connected piston rod 54,54 upper end of piston rod is fixedly connected on sliding block 51.Piston cylinder 55 and hydraulic cylinder 62(referring to
The connecting tube 58 for being connected to the two is fixedly connected between Fig. 2).When the tensile force of fabric is larger, sliding block 51 move up from
And flow into the hydraulic oil in hydraulic cylinder 62 in piston cylinder 55 by connecting tube 58, and then mitigate brake block 63 and brake disc 31
Between frictional force, the debatching speed of let off roll 3 is accelerated, to reduce tensile force.When the tensile force of fabric is smaller, sliding block
51 move down to make the hydraulic oil in piston cylinder 55 to flow into hydraulic cylinder 62 by connecting tube 58, and then increase brake block
Frictional force between 63 and brake disc 31, has slowed down the debatching speed of let off roll 3, to increase tensile force.In order to increase liquid
Thrust of the cylinder pressure 62 to brake block 63, diameter of 55 diameter of piston cylinder less than hydraulic cylinder 62.
As shown in figure 4, being arranged with multiple clump weights 57 on guide rod 53 and clump weight 57 and guide rod 53 are in being slidably connected, most
The clump weight 57 of lower section contradicts on piston cylinder 55.Clump weight 57 offers the abdicating through hole 573 passed through for piston rod 54.Piston rod
Horizontal multiple first connecting holes 541 are opened up on 54, and the second connecting hole 571, each first connecting hole are offered on clump weight 57
541 correspond to second connecting hole 571.Using connecting rod 572 also cross the first connecting hole 541 and the second connecting hole 571,
To connect clump weight 57 and piston rod 54, the pressure that idler roller 52 applies fabric is adjusted using clump weight 57, and
And the quantity by adjusting clump weight 57, to change the pressure that idler roller 52 applies fabric, and adjust clump weight 57
Quantity is convenient.
Specific working mode: when the tensile force of fabric is smaller, fabric applies thrust to idler roller 52 and reduces, to be tensioned
Roller 52 moves down under the effect of gravity, and then moves down with movable slider 51, so that the hydraulic oil in piston cylinder 55 be made to pass through
Connecting tube 58 flows into hydraulic cylinder 62, and then increases the frictional force between brake block 63 and brake disc 31, has slowed down let off roll 3
Debatching speed, to increase tensile force.When the tensile force of fabric is larger, fabric applies thrust to idler roller 52 and increases, from
And move up idler roller 52, and then move up with movable slider 51, so that the hydraulic oil in hydraulic cylinder 62 be made to pass through company
Adapter tube 58 flows into piston cylinder 55, and then reduces the frictional force between brake block 63 and brake disc 31, accelerates moving back for let off roll 3
Speed is rolled up, to reduce tensile force.
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.
