Description

Technical Field

[0001] The utility model relates to the technical field of belt winding aids, in particular to a belt tightening device for a winding aid. Background Art

[0002] After the aluminum alloy plate is rolled, it needs to be wound into a coil. An actively rotating core roller is used to wind the aluminum alloy plate. However, the aluminum alloy plate is prone to looseness when directly wound and cannot be tightly wound. At this time, a belt winding machine is used to assist in winding on the outside of the core roller to help the aluminum alloy plate to be wound more quickly and stably. However, when the belt winding machine is in use, the winding belt is prone to loosening due to long-term rolling, which in turn reduces the fit with the aluminum alloy plate and causes the aluminum alloy plate to be loosely wound when winding.

[0003] In order to solve the above technical problems, the Chinese utility model patent with the authorization announcement number CN219233549U discloses a belt auxiliary winding machine. The utility model pushes the tensioning roller outward through a tensioning telescopic pump, so that the rolling belt can always maintain the tension state and adjust in real time. During use, the problem of loose winding caused by belt slack is reduced and the winding quality is improved; by setting left and right limit arc plates and baffles under the steel belt of the winding core roller, the deviation problem of the steel belt during winding is prevented, and the accuracy and quality of steel belt winding are improved;

[0004] Although the technical solution provided by the utility model solves the problem that the existing belt winding machine is prone to loosening when using the winding belt, the width of the aluminum alloy plate needs to be produced according to actual needs, and the structure for preventing the aluminum alloy coil from deviating provided in the above solution cannot adapt to aluminum alloy plates of different sizes because the two baffles are plugged into the arc plate. When the width of the aluminum alloy plate is less than the distance between the two baffles, the baffle cannot limit the aluminum alloy plate. Therefore, the aluminum alloy plate will still deviate during the winding process, which will cause the quality of the aluminum alloy plate winding to decrease. Utility Model Content
