Description

Winder and sewing machine Technical Field The utility model relates to the technical field of sewing machines, in particular to a winder and a sewing machine. Background As shown in fig. 7, in the conventional sewing machine in the market, a winder 100 is installed on a casing 200, an upper shaft 300 is installed in the casing 200, and a rubber ring 150 at the bottom end of the winder 100 is connected with a driving wheel 400 installed on the upper shaft 300 through friction transmission, so that the winding shaft of the winder 100 is driven to rotate through the rotation of the upper shaft 300, thereby realizing the winding action. The winding machine is provided with a limiting device which can be automatically separated from the driving wheel after a certain winding amount is reached, so that the winding is stopped, and meanwhile, the winding machine is also provided with a limiting rod for adjusting the winding amount, and the winding amount can be controlled by changing the fixed position of the limiting rod. Patent document with publication number CN209619630U discloses a winding device of a sewing machine, which realizes the detection of the winding quantity through a sensor, but in the actual production process, the winding device has the following technical problems: 1. The installation of the sensor can lead the whole volume of the winder to be bigger, occupy larger space and be difficult to integrate in the main body of the sewing machine. 2. The problems of poor contact and insensitive response exist, and the normal operation of winding operation is affected. Therefore, how to reduce the volume of the winder and ensure the normal operation of the winding operation is a technical problem to be solved by those skilled in the art. Disclosure of Invention In view of the above, an object of the present utility model is to provide a winder.
