Description
Technical Field
[0001] The utility model belongs to the technical field of strip winding machines, and in particular relates to a stretching roller bracket for a strip winding machine. Background Art
[0002] The leather roller is one of the main parts of the traction device of the strip winder. The leather roller is in contact with the roller, and the cotton strips are stretched through the joint action of the roller and the leather roller. When the leather roller is in use, cotton threads will be entangled on the leather roller, and the shaft sleeve of the leather roller will be worn after a long period of use. Therefore, when the leather roller has serious winding or the shaft sleeve needs to be replaced, the leather roller is usually lifted and then removed from the strip winder to facilitate the staff to clean the leather roller and roller, and at the same time facilitate the staff to maintain or replace the leather roller shaft sleeve.
[0003] At present, the sleeves at both ends of the leather roller are placed on a fully enclosed spring steel bracket to achieve the overlap of the leather roller on the rocking frame. When disassembling the leather roller, it is usually necessary to forcefully pry the bracket apart or remove the bracket and the leather roller as a whole to ensure that the leather roller sleeve can be taken out from between the two brackets. The method of removing the bracket and the leather roller as a whole is time-consuming and labor-intensive, reduces work efficiency, and requires the strip winding machine to be shut down for a long time, reducing production efficiency; and taking out the leather roller by prying the bracket will cause wear to the threaded hole of the aluminum cylinder, and frequent prying of the bracket will damage the bracket, reducing the service life of the bracket and increasing maintenance costs. At the same time, for workers with less strength, the removal of the leather roller cannot be completed alone. Utility Model Content
