[0002] A winding machine is a device that winds a linear object onto a specific workpiece. During the winding process, the transmission winding machine fixes the winding shaft through a clamping device to prevent the winding from falling off when the motor drives the rotation.

[0003] The clamping device is usually slidably installed on the extended base of the winding machine. When the winding shaft is loaded with a workpiece, the clamping device needs to be moved relative to the end of the extended base. Since the clamping device is close to the winding shaft, it is easy to accidentally touch the clamping device when loading the workpiece, causing it to slide and affect the installation of the workpiece. Therefore, it is urgent to design a limiting structure to solve the above problem. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a limiting structure for a winding machine to solve the above problems.

[0009] The screw is fixedly mounted on the outside of the rotating block, and the extension line of the central axis of the screw is perpendicular to the extension line of the central axis of the rotating shaft;

[0010] The limit block is sleeved on the outside of the screw rod; wherein, a baffle is fixedly installed on one end of the extended base away from the machine body, and a limit groove for the limit block to be inserted into the middle of the upper end of the baffle is opened.

[0011] Furthermore, a bearing seat is fixedly installed on the upper end of the fixed seat, and the rotating shaft is rotatably connected to the upper end of the fixed seat through the bearing seat. A nut for axially locking the rotating shaft is sleeved on one side of the rotating shaft.

[0012] Furthermore, the limit block is in a cylindrical stepped structure, and an internal thread matching the screw rod is arranged on the inner wall of the limit block. Furthermore, the baffle is connected and fixed to the extended base by bolts.

[0013] Furthermore, a buffer block is fixedly mounted on one side of the baffle plate facing the clamping device, and the buffer block is located on the moving path of the extension portion.

[0014] Furthermore, the distance between the clamping device and the bearing seat is smaller than the length of the screw.
