Description

Technical Field

[0001] The utility model relates to the technical field of tobacco machinery, in particular to a corrugated paper box lining cardboard clamping device for unpacking tobacco leaves. Background Art

[0002] In the tobacco industry's tobacco leaf processing process, a multi-axis gripping robot arm, coupled with a corresponding multi-functional clamp, is typically used to separate packaging materials such as inner and outer packaging cartons, plastic bags, and corrugated cardboard liners from the tobacco block, completing the tobacco leaf unpacking process. The corrugated cardboard liner is laid flat on top of the tobacco block. The clamps currently used in multi-axis gripping robots use barbed steel nails to penetrate the liner, clamping the liner using the combined effects of friction between the nail and the cardboard and the barbs. However, this clamping method requires a very high level of sharpness from the nail tip. If the nail tip is worn or scale accumulates on the surface, the hole through which the nail penetrates the cardboard becomes larger, significantly reducing the barbs and friction, resulting in failure to pick up the cardboard or loosening of the cardboard during movement of the robot arm. Utility Model Content

[0026] Example:

[0027] refer to Figure 1As shown, a corrugated paperboard lining clamping device for unpacking tobacco leaves includes a hollow shell 1, which is fixedly mounted on a mechanical mobile phone frame 11. Two cylinders 12 are provided on the mechanical mobile phone frame 11 in the hollow shell 1. The two cylinders 12 are provided with a piston rod 121. The two piston rods 121 are connected to the cylinders 12 at one end and connected to the steel nail 21 through a first hinge 22. The mobility of the hinge is utilized to enable the steel nail 21 to have a certain left and right offset movement. The piston rod 121 is driven to move by the cylinder 12, and the piston rod 121 drives the steel nail 21 to move.

[0028] Among them, the connecting ends of the steel nail 21 and the first hinge 22 are provided with pointed heads 211, which are convenient for inserting into the lining cardboard.

[0029] Positioning blocks 14 are provided on the side surfaces of the hollow shell 1 next to the two piston rods 121 , and the positioning blocks 14 are used to limit the movable angle of the piston rods 121 .

[0030] It should be noted that in order to ensure the air tightness of the two cylinders 12, the piston rod 121 must remain vertical to the cylinder 12. Therefore, the positioning block 14 is used to limit the left and right movement angle of the piston rod 121, and only the steel nail 21 part at the lower part of the first hinge 22 can achieve left and right movement.

[0031] A slot 13 is provided on the hollow shell 1, and a concave block 131 is provided on the slot 13 in the middle of the two steel nails 21. A groove 131a is provided on the concave block 131, and a positioning rod 31 is movably connected in the groove 131a. The positioning rod 31 is connected to the connecting rod 33 through the second hinge 35 on both sides of the steel nail 21. The connecting rod 33 is connected to the two steel nails 21 through the limit hinge 34 respectively. The bottom end of the positioning rod 31 is fixedly connected to the impact block 32.

[0032] The slot 13 can provide an installation channel for the installation of the steel nail 21.

[0033] The limiting hinge 34 is used to ensure that the steel nail 21 is fixed at a specific angle after being stretched outward to prevent it from swinging due to external force, resulting in unstable fixation of the lining cardboard.

[0034] Among them, the left and right steel nails 21 and the positioning rod 31 are connected into a whole through the limiting hinge 34 and the connecting rod 33. The tail of the positioning rod 31 is embedded in the groove 131a of the concave block 131, and the groove 131a limits the vertical movement distance of the positioning rod 31.

[0035] In another embodiment, the impact block 32 is movably connected to the positioning rod 31 through a positioning nut, so that the vertical position of the impact block 32 can be adjusted by the positioning nut to meet the needs of grabbing the liner cardboard under different working conditions.

[0036] Among them, the connecting rod 33 is in an inclined state, so that the two connecting rods 33 form a V shape. When the positioning rod 31 moves upward, the two connecting rods 33 gradually form a straight line, thereby changing the angle of the steel nail 21 and increasing the friction between the steel nail 21 and the lining cardboard.

[0037] The working principle of this utility model is:

[0038] When the manipulator moves to the clamping position, the piston rod 121 moves downward under the drive of the two cylinders 12, and the piston rod 121 drives the steel nail 21 to move downward. The steel nail 21 drives the positioning rod 31 to move downward through the connecting rod 33, and the steel nail 21 pierces the liner cardboard until the collision block 32 contacts the top of the cigarette block (on the liner cardboard). When the steel nail 21 continues to move downward, the collision block 32 is vertically pushed upward until the tail of the positioning rod 31 coincides with the bottom of the groove 131a. In this process, the positioning rod 31 drives the two connecting rods 33 to gradually form a straight line, so that the steel nail 21 is stretched outward to clamp the liner cardboard. The limit hinge 34 fixes the angle of the movable steel nail 21 to prevent the steel nail 21 from moving and the liner cardboard from falling off during the grasping movement.

[0039] When the manipulator moves to the cardboard recovery position, the two cylinders 12 drive the piston rod 121 to move upward, and the piston rod 121 drives the steel nail 21 to move upward. The steel nail 21 drives the positioning rod 31 to move upward through the connecting rod 33. Due to the groove 131a, the positioning rod 31 cannot move upward. Under the action of the connecting rod 33, the angles of the steel nails 21 on both sides shrink inward so that they cannot get stuck in the lining cardboard. At the same time, the steel nails 21 shrink into the hollow shell 1. Finally, the lining cardboard is blocked by the bottom of the hollow shell 1 and detaches from the steel nails 21, causing the lining cardboard to fall off to the recovery point.

[0040] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
