Winding tension adjustment device in traction winder

Abstract

The invention discloses a winding tension adjusting device in a traction winding machine. A winding roller is arranged on a rack through a third bearing pedestal and driven by a variable frequency motor. A base is arranged on the rack and fixedly provided with at least three pressure sensors. All the pressure sensors and the variable frequency motor are connected with a control circuit, and the control circuit can receive and process signals transmitted by the pressure sensors and control the rotating speed of the variable frequency motor in a feedback manner. A floating roller is arranged on the pressure sensors through a floating bearing pedestal, and a first pressing roller and a second pressing roller are arranged on the two sides of the floating roller respectively. Wound articles are sequentially wound through the floating roller and the second pressing roller from the first pressing roller and then wound on the winding roller. The winding tension adjusting device has the beneficial effect that it can be guaranteed that winding tension is kept stable in the winding process of the traction winding machine.

Description

technical field [0001] The invention relates to a traction winder, in particular to a winding tension regulating device capable of adjusting the winding tension of a rewinding object during the winding process of the traction winder. Background technique [0002] The plastic extruder can heat the plastic to make it into a viscous flow state, and then make it pass through a die with a certain shape under pressure, and finally form a continuum with a cross-sectional shape similar to the shape of the die, and then make the continuous body through cooling. The body is shaped into an extrudate with a certain geometric shape and size. Extruded sheets such as PP extruded sheets and PVC extruded sheets that are common in the market are all extruded by plastic extruders. The traction winder is an important auxiliary machine of the plastic extruder. The extrudate such as PP sheet is evenly pulled out from the die of the plastic extruder through the traction device in the traction wind...

AI Technical Summary

Problems solved by technology

Here, the extrudate that is ready to be transported to the winding device for winding operation is called the rolled object, and the extruded product that has been wound on the winding roller is called the rolled object. The winding device performs the winding operation by winding the object to be wound on the winding roller. The winding roller is driven by the motor to rotate. During the operation, the diameter of the winding object wound on the winding roller will change with the As the number of rewinding objects increases, the volume becomes larger. If the speed of the rewinding roller remains unchanged, the winding tension will also increase with the increase of rewinding objects during the rewinding process. Whether it is stable or not will be directly related to the quality of the rewinding material, and will also affect the stability of the traction winder. Therefore, it is necessary to ensure that the winding tension remains stable during the winding process, and the current traction winder is not very good. Ensure that the winding tension remains stable during the winding process
