Description

Technical Field

[0001] The utility model relates to the technical field of a case making machine, in particular to a rounded corner forming die for a case making machine. Background Art

[0002] The cover machine is also called the edge binding machine or the leather shell machine. It is divided into manual cover machine, semi-automatic cover machine and fully automatic cover machine. The whole production process includes steps such as cover gluing, positioning and four-sided edge binding. It is suitable for various book covers, book boxes, folders, chessboards, desk calendars and other related products. The common leather shell machines in the industry are mainly composed of three parts: the gluing device, the composite positioning device, and the four-sided edge binding device. After the printed packaging paper is glued by the roller of the gluing equipment, it enters the composite positioning device, picks up the cardboard through the suction device, and pastes the cardboard with the packaging paper placed on the composite positioning device. After that, the cardboard with the pasted packaging paper is transported to the four-sided edge binding device for edge binding. However, the current four-sided edge binding device can basically only process the leather shell with regular corners and glue binding. For the leather shell with rounded corners, it is generally pressed by manual force to fillet the corners, which has low work efficiency and production quality and high manufacturing cost.

[0020] The utility model is described in detail below with reference to the accompanying drawings.

[0021] like Figures 1 to 3 As shown, the utility model is a rounded corner forming mold for a case making machine, comprising a base 1, a mounting base 2 arranged on the base 1, a forming base 3 slidably arranged on the base 1, and a connecting member 4 arranged among the mounting base 2, the base 1, and the forming base 3, the connecting member 4 passes through the mounting base 2 and the base 1 and is connected to the forming base 3, a corner block 31 is arranged on the outer side of the forming base 3, the corner block 31 is convexly provided with a first rounded corner push surface 32, a second rounded corner push surface 11 is convexly provided on one side of the base 1 close to the first rounded corner push surface 32, the bottom surface of the first rounded corner push surface 32 is fitted and abutted against the top surface of the second rounded corner push surface 11, so that the first rounded corner push surface 32 is vertically aligned with the second rounded corner push surface 11.

[0022] When working, the forming seat 3 slides along the length direction of the base 1, effectively adjusting the position of the forming seat 3 on the base 1, so that the connecting member 4 passes through the mounting seat 2 and the base 1 and is connected and fixed on the forming seat 3. At this time, the bottom surface of the first rounded corner push surface 32 fits and contacts the top surface of the second rounded corner push surface 11, so that the first rounded corner push surface 32 and the second rounded corner push surface 11 are aligned in the vertical direction, which can adaptively adjust the forming height of the rounded corner, increase the contact area of ​​the rounded corner, and make the rounded corner work more comprehensive, efficient and faster to form. Then, the mounting seat 2 is connected and fixed to the external skin shell machine, and then the entire rounded corner forming mold is fixedly installed on the external skin shell machine. Under the drive of the external skin shell machine, the vertically aligned first rounded corner push surface 32 and the second rounded corner push surface 11 jointly push the rounded corner folding edge on the cardboard with the packaging paper pasted, thereby realizing the regular forming of the rounded corner, improving the forming beauty of the rounded corner, effectively replacing the manual operation method, saving production time, reducing labor costs, improving production capacity benefits, and ensuring product quality and precision.
