technical field

The utility model relates to the technical field of film blowing extruder production, in particular to an automatic winder tension control and roll change buffer device.

Background technique

The film blowing machine heats and melts the plastic particles and blows them into a film. Add the dry polyethylene particles into the lower hopper, and enter the screw from the hopper by the weight of the particles themselves. Moving forward, due to the friction between the plastic and the screw, the plastic and the barrel, the collision and friction between the particles, and the external heating of the barrel, it gradually melts. The molten plastic is filtered by the machine head to remove impurities and comes out from the die opening of the die head. However, in the existing coiling device, when the coil is changed, the motor speed of the film and the main coiler will increase due to carelessness, and the increase of the film tension will cause the film to be damaged, which cannot be automatically controlled, and there is no buffer device. Therefore, we propose an automatic winder tension control and roll changing buffer device.

Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

Please refer to Figures 1-3, the present utility model provides a technical solution: an automatic winder tension control and roll change buffer device, comprising an automatic roll change overturn arm 2 and a low-friction cylinder 3, characterized in that: the automatic winder The right end of the rewinding arm 2 is fixed on the central axis of the rewinding rubber roller 10 through a bearing, the rotation center of the automatic rewinding and reversing arm 2 is coaxial with the rewinding rubber roller 10, and the top of the low-friction cylinder 3 is provided with Potentiometer 4, the top of the left side of the piston rod of the low-friction cylinder 3 is provided with a floating roller swing arm 5 through a pin, and the top of the floating roller swing arm 5 and the back of the low-friction cylinder 3 are all set on the wall through the pin. On the plate 11, the lower end of the floating roller swing arm 5 is provided with a floating roller 6, and the wall panels 11 on the upper and lower sides of the low-friction cylinder 3 are respectively provided with guide rollers 7 and flattening rollers 8. The upper end of the guide roller 7 leads to the beginning end of the film 9 , and the trailing end of the film 9 bypasses the floating roller 6 and the flattening roller 8 in sequence and then leads to the winding rubber roller 10 .

The pull rod of the potentiometer 4 is connected to the piston rod of the low-friction cylinder 3 through a connecting piece, the floating roller swing arm 5 is H-shaped, and the low-friction cylinder 3 and the floating roller swing arm 5 are fixed on the On the wall panel 11 , a floating roller 6 is provided at the bottom end of the floating roller swing arm 5 .

Working principle: first power on the device, then guide the film 9 to the floating roller 6 through the guide roller 7, and then guide it to the rewinding rubber roller 10 through the flattening roller 8. When the roll is full, the main motor will rewind the rubber roller 10. When turning from the lower side to the upper side, since the automatic roll changing and turning arm 2 is set on the winder through the bearing, the left end of the automatic roll changing turning arm 2 is placed on the wall panel 11, and it is fixed there all the time. When the 10 is brought to the upper side of the automatic roll changing and turning arm 2, the rotating arm blocks the central axis of the film roll, leaving the film roll to realize the operation of automatically lowering the film roll. The roller 10 drives the film 9 to be tensioned instantly. Under the pulling force of the film 9, the floating roller swing arm 5 swings from the natural vertical position to the direction of the rewinding rubber roller 10. Since the floating roller swing arm 5 is provided with a pin, it can play a The buffering effect prevents the film 9 from being overstretched and deformed or broken. When the floating roller swing arm 5 swings, the connecting piece of the potentiometer 4 is driven by the low-friction cylinder 3, and the electrical control system receives the signal of the potentiometer 4 to change the size. Adjust the speed of the main motor and the motor of the rewinding rubber roller 10 to a suitable speed to keep the tension constant. When the reeling rubber roller 10 turns to the upper side, the two sides of the reeling rubber roller 10 are stuck on the upper side of the wall panel 11. The central axis of the film roll can be successfully rolled up, and realize automatic tension control and roll change buffer. The device has simple structure, convenient operation, low maintenance and strong practicability.
