Description

Technical Field

[0001] The utility model relates to the field of corrugated cartons, in particular to a transfer vehicle for corrugated carton production. Background Art

[0002] A corrugated cardboard (box) is a rigid paper container made of corrugated cardboard, and the corrugated cardboard is made of wood fibers, which can be naturally degraded and recycled. It is a globally recognized green environmental protection packaging product. During the production process of corrugated cartons, corrugated cardboard needs to be transferred between multiple processing machines. For the convenience of transfer, ground rollers, transfer trolleys, etc. with upper surfaces flush with the loading and unloading platforms of machines such as printing presses are provided in the workshop.

[0003] For example, the Chinese patent with the patent application number CN201420846764.8 discloses "A corrugated carton transfer vehicle". By setting a pull rod and a hanging ring on the vehicle frame, it is convenient for the transfer vehicle to stop and move forward. And through the setting of a movable front baffle, it is convenient for loading and unloading. When unloading, the arc structure at the right end of the front baffle can buffer the unloading, playing a role in facilitating loading and unloading.

[0004] This structure has certain advantages, but there are still some deficiencies:

[0005] During the process of transferring folded and bundled corrugated cartons, unloading is achieved by lowering the front baffle, and rollers are arranged inside the bottom end of the transfer vehicle to assist unloading. If multiple bundled corrugated cartons are loaded, the bottom corrugated cartons are unstable under the acting force of the upper layer moving during loading, which is not conducive to safe unloading. And if all corrugated cartons are unloaded synchronously, under the action of the rollers and the inclined front baffle, the inertia of the corrugated cartons sliding down increases, there are safety hazards. And the existing corrugated carton transfer vehicles stack multiple bundled corrugated cartons layer by layer. When loading and unloading, the cartons can only be pulled out by the bundled ropes and then unloaded. This method has the situation that the ropes are loosened and it is laborious to move out, which is not conducive to improving the operation speed of corrugated cartons in multiple processing machines. Content of the Utility Model

The assembly 61 is installed inside the frame 1, and an installation groove 62 is provided inside it. An electric cylinder 64 is bolt - fixed inside the installation groove 62. The left end of the support frame 63 is fixed to the assembly 61, and its top end is in contact with the electric cylinder 64. The right end of the electric cylinder 64 is bolt - fixed with a pushing plate 67. The left end of the connecting plate 65 is locked and fixed to the assembly 61 with bolts, and a placing groove 66 is formed inside it. The inside of the placing groove 66 is in contact with the pushing plate 67. The left end of the fixing member 68 is fixed to the assembly 61.

[0028] In this embodiment, multiple groups of electric cylinders 64 and fixing members 68 are provided, which are evenly distributed at equal intervals in the vertical direction, and a group of fixing members 68 are horizontally installed corresponding to the installation position of a group of electric cylinders 64, which is convenient for fixing the stacked cardboard boxes and avoiding the unsafe situation that the lower - layer cardboard boxes will also move when the upper - layer electric cylinder 64 pushes the upper - layer cardboard boxes out. The cross - section of the placing groove 66 is in a "convex" shape, which is convenient for the installation of the electric cylinder 64 and the connecting plate 65, and is also convenient for placing the connecting plate 65, so that the connecting plate 65 is hidden inside the placing groove 66, enabling the cardboard boxes to be stacked stably and neatly inside the frame 1. Among them, when the electric cylinder 64 needs to be maintained, first remove the pushing plate 67 with bolts, and then remove the connecting plate 65 to expose the internal electric cylinder 64 for maintenance.

[0029] In addition, when installing the electric cylinder 64, the bottom end of the electric cylinder 64 is pressed against the support frame 63, and then the left end bolt of the electric cylinder 64 is installed in the installation groove 62. This method effectively supports the electric cylinder 64 and improves the stability of the installation of the electric cylinder 64.

[0030] In this embodiment, the spacing between the two groups of electric cylinders 64 is adapted to the height of each bundled corrugated cardboard box, so that the electric cylinders 64 can push the corresponding layers of corrugated cardboard boxes one by one, and the transfer vehicle can only stack two groups of corrugated cardboard boxes on the left and right sides in a single layer, so that the electric cylinders 64 can push the two groups of corrugated cardboard boxes out at the same time, wherein each group of electric cylinders 64 is controlled separately, and the start-up of each group of electric cylinders 64 is controlled by different lines of the control box 5.
