Paper tube flat roll machine

This creation is about a paper tube manufacturing equipment, especially a paper tube flat winder.

Press, the paper tube flat roll machine is a machine that can make a long strip of paper tape into a paper tube by winding and gluing procedures. The Republic of China Patent No. 370006 "flat roll type reel machine" reveals A typical paper tube flattening machine is mainly composed of a winding device, a pressure roller device, a cutting device, a gluing device and a retracting device, wherein the take-up shaft of the winding device is used for Winding the component of the paper tube (which determines the inner diameter of the paper tube), the "rolled reel unit" is rotated over the take-up shaft by rotating the pressing wheel of the control roller device Rolling the shaft to make the tape complete the winding of the first turn, and then, through the glue wheel of the gluing device, the paper tape is glued, so that the paper tape can be glued to each other during the winding process of the subsequent turns to form For the paper tube, finally, the cutting of the paper tape and the material returning operation of the paper tube finished by the cutting device and the unloading device are respectively performed, thereby realizing the automated paper tube manufacturing operation.

In the forming process of the paper tube, it is very important to let the paper strip smoothly complete the winding of the first ring. Specifically, this involves how to make the paper tape firmly adhere to the surface of the take-up shaft so that the winding takes place. When the shaft rotates, the paper tape can be driven to be wound into a loop. For this point, the existing paper tube flattening machine mainly applies an appropriate range of adhesive or adhesive tape between the take-up shaft and the beginning end of the paper tape. To attach the paper tape to the take-up reel and form a gripping force, but this type of operation must It must be carried out manually, thus increasing manpower requirements and reducing production efficiency. For this reason, the Republic of China Patent No. I361140 "Paper Pipe Manufacturing Apparatus and Paper Tube Manufacturing Method" discloses that it can be used in a hollow molding die (similar to the aforementioned winding Positioning the air hole on the shaft), and then using the negative pressure suction generated by the positioning air hole to adsorb the structure and principle of the paper tape, but the hollow plastic mold does not form the paper tube in a rotating manner, and therefore, it is generally required to be utilized. In the case of a take-up reel that is rotated to wind the formed paper tube, if only the suction hole is used and the paper tape cannot be supplied with sufficient tension or gripping force, the paper tape may be driven or wound by the take-up shaft. When the raw roller is slid or offset relative to the winding axis, the actual actual winding number of the paper tube is abnormal or other quality defects, which affect the product yield and reduce the reliability of the device. Therefore, how to improve the above defects That is, the technical difficulties that the applicant of the case wants to solve.
