Description

technical field [0001] The invention belongs to the technical field of film winding equipment, and in particular relates to an automatic unwinding and winding device and an automatic unwinding and winding method. Background technique [0002] After the film is produced, it needs to be wound up into a coil by winding equipment. The winding equipment includes a winding shaft and a winding bracket for supporting both ends of the winding shaft. The winding bracket is equipped with a rotatable plug. The tapered jacks at the two ends of the winding shaft respectively form a movable plugging relationship with the plugs on the corresponding sides, and the winding support is also equipped with a winding motor that drives the plugs to rotate. [0003] Most of the film needs to be applied to the paper core tube during the winding process. The paper core tube is set outside the winding shaft, and the paper core tube is driven by the winding shaft to rotate continuously, so that the fil...

Problems solved by technology

However, the above-mentioned unloading trolley is only suitable for the film roll unloading process involving the paper core tube winding method, but not suitable for the film roll unloading process of the optical axis winding method, which is the result of the joint action of the following factors : First, the weight of the film roll is heavy, and the top panel of the unloading trolley bears a large load when carrying the film roll, which means that the power mechanism that drives the top panel of the unloading trolley to rise is a hydraulic mechanism with a large force; The weight of the roll is heavy, so when the film roll is transferred from the winding stand to the top panel of the unloading trolley, the top panel of the unloading trolley must be in close contact with the lower surface of the film roll, that is, there should be no vertical gap between the two. Otherwise, the film roll will have a free fall stroke, which will generate large vibrations, and even impact and damage the unloading trolley; third, due to the large difference in the winding diameter of various film materials, the above power mechanism In the rising process of driving the top panel of the unloading trolley, it is actually impossible to stop the power output just when it touches the surface of the film roll, but generally in order to ensure that the top panel of the unloading trolley closely contacts the lower surface of the film roll, the hydraulic mechanism must It will strongly impact the lower surface of the film roll upwards; for the paper core tube winding method, due to the gas buffering effect of the air expansion shaft and the paper layer buffering effect of the paper core tube, this upward impact is transmitted to the two sides of the winding shaft. However, for the optical axis winding method, due to the absence of the gas buffering effect of the air shaft and the buffering effect of the paper layer of the paper core, the tightly wound plastic film roll has a high hardness. Therefore, this upward impact force will be greatly transmitted to both ends of the winding shaft, and then damage the plug connected to the end of the winding shaft and the winding power mechanism (winding motor)

[0008] Therefore, for the optical axis winding method, in the prior art, the unloading and winding process after winding is not suitable for unloading trolleys with traditional structures, which mainly rely on manual work, with low automation and high labor intensity. time consuming
