Description

Edge covering assembly of leather shell machine Technical Field The invention relates to a wrapping assembly of a leather shell machine. Background The leather shell machine is used for manufacturing leather shells, and the paper board and the facial tissues are pasted and then used as main materials to be matched and conveyed for subsequent edge wrapping, wherein the lower surface of the paper board and the facial tissues are pasted, the pasted materials are conveyed for subsequent edge wrapping, and the facial tissues (pasted on) on the lower surface of the paper board are turned over and wrapped on the edges of the paper board to complete corresponding edge wrapping. In the leather shell machine, the edge position of the paperboard is required to be covered by facial tissues, for example, in a novel leather shell machine of CN218257126U and other equipment, four side edges of the paperboard are respectively covered, the left side and the right side of the paperboard are covered by arranging torsion belts in the forward conveying process, the left side and the right side of the paperboard are covered by arranging the torsion belts in the left side and the right side, and then the front side and the rear side of the paperboard are covered by continuously conveying the materials, wherein when the materials are continuously conveyed by adopting a conveying belt, corresponding covering mechanisms can be configured at the feeding end and the discharging end of the conveying belt to be matched with the front side and the rear side of the paperboard to be respectively covered. After the material is input onto the conveyor belt, the conveyor belt forwards transfers the material, so that the rear side edge of the paperboard is positioned at the feeding end of the conveyor belt, and the conveyor belt stops once at the feeding end of the conveyor belt, so that the rear side edge of the paperboard is covered, and after the rear side edge is covered, the conveyor belt starts to forward transfer the material together with the conveyor belt again; If the conveyer belt is matched with the front side edge for edge wrapping in the forward conveying process (such as a novel shell machine of CN218257126U, an edge folding hammer of a front edge folding mechanism of CN210553353U, an edge folding block of a front edge wrapping mechanism of the shell machine of CN219214257U and the like), the problem that the edge wrapping is not compact and is not easy to adapt to the requirements of special-shaped edge wrapping exists, Or if the conveyer belt is stopped again in the process of matching with the advancing and transferring, and the conveyer belt is used for wrapping in other modes, the conveyer belt is conveyed for a plurality of times (such as twice) in the process of wrapping the paper board front and back, and the speed and the efficiency are affected by respectively wrapping the paper board front and back in a stop matching manner. In addition, the relative positions of the front and rear edges are different due to the different dimensions (e.g., front and rear lengths) of the cardboard, and the conveyor belt requires multiple (e.g., two) conveyor runs to engage the front and rear edges to the respective positions for the taping operation. In addition, the effect of the binding mode of the binding plate matched with the turnover facial tissues to cover the edges of the paperboards is relatively good, the binding is compact, and the binding requirement of special-shaped edges (such as hypotenuses, triangular V-shaped edges, arc-shaped edges and the like) can be met. For example, the initial position of the edge covering plate is located at the lower side of the paperboard, after the materials are conveyed in place, the edge covering plate is driven to ascend to upwards fold the facial tissues beyond the edge part of the paperboard, then the edge covering plate is driven to move towards the center direction of the paperboard, the upward folded facial tissues are folded to the upper side of the paperboard to cover the upper side of the paperboard, edge covering is completed in a matching mode, and then the edge covering plate is retracted and reset to wait for the next operation, wherein the whole structure of the edge covering mechanism adopting the edge covering plate needs to occupy a certain space position for assembly. The whole edge covering mechanism is arranged on the equipment base in a bearing mode, the back waiting position and the edge covering initial position of the edge covering plate are located below the paperboard and are located at low positions, the whole edge covering mechanism can move upwards (vertically or obliquely) directly when in operation, the whole edge covering mechanism can be arranged beside the conveying belts or interpenetrates between the conveying belts or at the concave positions of the conveying belts or at the edges of the working tables in a bearing mode, however, for occasions with limi
