Detailed Description

In order to make the technical means, the creation features, the achievement purposes and the functions of the present invention easy to understand and understand, the present invention is further explained by combining the following specific drawings.

As shown in fig. 1-3, the traction device of the TPU composite film forming apparatus includes a frame 1, two positioning rollers 2, two adjusting rollers 3, a rotating rod 4 and a balancing weight 5.

Specifically, two registration rollers 2 are all installed in framework 1, and two regulating rolls 3 are located between two registration rollers 2, and both ends rotate jointly and are connected with fixed plate 6, and two fixed plates 6 rotate through fixed axle 7 and framework 1 and are connected. The TPU film 12 can be pulled by the two positioning rollers 2 and the two adjusting rollers 3, and the two adjusting rollers 3 rotate on the frame body 1, so that the tension of the TPU film 12 can be adjusted.

In a specific implementation mode, a TPU film 12 is arranged in the frame body 1, and two ends of the TPU film 12 sequentially bypass the two positioning rollers 2 and the two adjusting rollers 3 and penetrate through two side walls of the frame body 1 and extend outwards.

In some specific implementation manners, the two fixing plates 6 are connected through the U-shaped connecting plate 13, and the two U-shaped connecting plates 13 are disposed on the upper and lower sides of the two fixing plates 6, so that the two fixing plates 6 can be stably connected to each other, and the stability of the rotation angle of the two adjusting rollers 3 is improved.

In this embodiment, bull stick 4 is located the outside of framework 1, and is fixed rather than one of them fixed axle 7, and balancing

weight

5 and 4 slip cap of bull stick are established, and be equipped with the locating part of 4 joints of bull stick, can press through the gravity of balancing weight 5 self and move bull stick 4 and rotate around fixed axle 7, and then drive two regulating rollers 3 and rotate, and guarantee to rotate the in-process and be the constant force to the tension that TPU membrane 12 was applyed, and then guarantee the towed stability of TPU membrane 12.

In some specific implementation manners, the rod wall of the rotating rod 4 is provided with a scale 14 for identification, so that the moving position of the balancing weight 5 can be better checked.

In this embodiment, the locating part includes cardboard 8 and screw rod 9, and the inner wall of balancing weight 5 is offered and is used for the arc wall that cardboard 8 accomodate, and the screw hole that is used for 10 threaded connection of screw rod is offered to the tank bottom of arc wall, and the one end and the cardboard 8 of screw rod 9 rotate to be connected, and the other end wears out the screw hole and extends to the outside of balancing weight 5. Through sliding balancing weight 5, can improve the length of moment when connecing bull stick 4 atress, and then the moment of torsion that bull stick 4 applyed fixed axle 7, and then the size of adjusting tension value.

The rethread rotates screw rod 9, can make it at screw hole internal rotation and removal, and then promotes cardboard 8 and remove, makes cardboard 8 support tightly with bull stick 4, realizes prescribing a limit to the position of balancing weight 5, prevents its self-sliding, is convenient for adjust balancing weight 5 to assigned position.

In some specific implementations, an operating rod 10 is fixedly connected to an end of the screw 9 extending outside, so as to facilitate rotation of the screw 9.
