Traction winding machine

Abstract

The invention discloses a traction winding machine. A traction device, a cutting device, a winding tension adjusting device and a winding device are arranged on a machine frame. The winding device comprises a winding roller which is arranged on the machine frame by being supported by a third bearing seat, and the winding roller is driven by a variable-frequency motor. An object to be wound sequentially passes through the traction device, the winding tension adjusting device, the cutting device and the winding device and then is wound on the winding roller. A rubber bent roller is arranged between the cutting device and the winding device and arranged on the machine frame through a fourth bearing seat. The object to be wound which is output from the cutting device winds across the top of the rubber bent roller from the front side of the rubber bent roller and then reaches the rear side of the rubber bent roller, and then the object to be wound is wound on the winding roller of the winding device. The traction winding machine has the advantages that the traction effect is good, and it can be guaranteed that in the winding process, winding tension is kept stable, the wrinkling phenomenon of the wound object is avoided, operation workers do not need to pull out the object to be wound from the position below a cutter, and using is quite safe and reliable.

Description

technical field [0001] The invention relates to the field of pulling and winding equipment, in particular to a pulling and winding machine for pulling and winding extruded products extruded from a plastic extruder. 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. At present, the commonly used traction winder includes three main components: the traction device, the cutting device and the winding device. For example, ...

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 rewinding object, and the extrudate that has been wound on the winding roller is called the rewinding object, and the rewinding object is sequentially passed through the traction device, cutting device, and winding device are wound on the winding roller in the winding device, and the winding roller is driven by a frequency conversion motor. During operation, the diameter of the winding object wound on the winding roller will change with the As the number of rewinding objects increases, 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, and the rewinding tension during the rewinding process will Whether it can be kept stable will be directly related to the quality of the rewinder, and it 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. Good guarantee that the winding tension remains stable during the winding process

In addition, the object to be wound between the winding rollers from the traction device to the winding device is prone to wrinkles, which makes the object not to be wound smoothly on the winding roller
