Description

Edge rolling machine for opening of paper barrel Technical Field The invention relates to the technical field of paper barrel production, in particular to a paper barrel opening edge rolling machine. Background The round paper barrel is a cylindrical packaging container, is widely used in the industries of chemical industry, food, medicine and the like, and has the characteristics of environmental protection, moisture resistance, compression resistance and the like. The production process of the round paper barrel comprises the steps of cutting the paper, winding drums, barrel rolling marks, flanging, bottom pressing, veneering, edge rolling and the like, wherein the edge rolling refers to processing of a semi-finished round paper barrel. The earlier technique of shaping the edge of the barrel opening is to use a hydraulic press and a die to press, and then to use a rotary elbow die and an edge control disc to perform edge rolling operation, such as the Chinese patent with the publication number of CN201291612Y, the Chinese patent with the publication number of CN202517760U, the Chinese patent with the publication number of CN103085337B, the Chinese patent with the publication number of CN201405546Y, the Chinese patent with the application publication number of CN101927583A, the Chinese patent with the publication number of CN200960744Y, the Chinese patent with the publication number of CN101168306B and the Chinese patent with the publication number of CN211467655U, are all proposals and improvements of the technique. Taking the Chinese patent with the issued bulletin number of CN211467655U as an example, the Chinese patent discloses a forming device for the edge of the opening of a full paper barrel, which comprises a frame, a main shaft is vertically inserted at the upper part of the frame through a bearing, the upper end of the main shaft is in transmission connection with a motor, the upper end of the main shaft sleeved in the main shaft is connected with a cylinder piston rod, the lower end of the main shaft is provided with an edge rolling die, the lower end of the main shaft is provided with a control disc matched with the edge rolling die, and a barrel clamp assembly which is radially adjustable along the paper barrel to be rolled is movably arranged at the lower part of the frame through a sliding assembly. The control panel of the Chinese patent is a whole, the control panel descends after the edge rolling is finished, and the end part of the drum after the edge rolling is inwards formed into a certain structure. When the round paper barrel is taken down, the round paper barrel is required to be slightly deformed by force extrusion after being inclined, then the round paper barrel is taken out from the control panel and the edge rolling die, the deformation process and the taking-out process can possibly cause the hidden quality hazards of strength reduction, inner wall scratch and the like of the round paper barrel, and the work personnel is inconvenient to take out the paper barrel after edge rolling. Disclosure of Invention The invention aims to provide a paper barrel opening edge rolling machine which is used for rolling edges of round paper barrels and has the effects of conveniently taking out the paper barrels after the edges are rolled and reducing damage to the paper barrels in the process of taking the paper barrels. The technical aim of the invention is achieved by the following technical scheme that the paper barrel opening edge rolling machine comprises an edge rolling die, a control panel and an adjusting mechanism, wherein the control panel comprises a plurality of panel bodies, and the adjusting mechanism is used for adjusting the panel bodies to be close to or far from the center of the control panel. By adopting the technical scheme, the edge rolling die is also called an elbow die, and is matched with the control panel to finish edge rolling operation. The control panel is divided into a plurality of panel bodies, after the edge rolling operation is finished, the adjusting mechanism adjusts all panel bodies to move towards the center of the control panel, a large gap is formed between the control panel and the edge rolling die, and at the moment, the round paper barrel can be separated from the edge rolling die and the control panel along the axial direction, so that the discharging is convenient, and the damage to the round paper barrel in the discharging process is reduced. The invention is further provided with a movable gap between two adjacent disc bodies, wherein the disc bodies are provided with limit strip-shaped holes, and the control disc is provided with limit pieces which pass through the limit strip-shaped holes and are fixed on the edge rolling die. By adopting the technical scheme, the control panel in the prior art is a whole disc, and the control panel does not rotate along with the edge rolling die during edge rolling operation. In the invention, as the control
