Description

Technical Field

[0001] This utility model relates to the field of food packaging technology, and in particular to a mechanical gripping mechanism for plastic edible oil packaging bottle preforms. Background Technology

[0002] Edible oil refers to animal or vegetable fats used in food production. After processing, edible oil needs to be packaged in bottles, which are then removed from the production equipment by mechanical grippers.

[0003] Chinese patent document CN219132343U discloses a robotic arm gripper. Several gripping mechanisms are rotatably connected to a mechanical frame. Each gripping mechanism is connected to a drive rod, and several pressing mechanisms are connected to different gripping mechanisms. Each pressing mechanism includes a second fixed base, a second connecting block, an arc-shaped plate, and an anti-slip pad. The second fixed base is fixedly connected to the gripping mechanism, the second connecting block is rotatably connected to the second fixed base, the arc-shaped plate is fixedly connected to the second connecting block, and the anti-slip pad is fixedly connected to the arc-shaped plate. The gripping mechanisms drive the arc-shaped plate to rotate. After contacting a cylindrical object, the arc-shaped plate rotates around the second fixed base via the second connecting block. The concave surface of the arc-shaped plate contacts the cylindrical object through the anti-slip pad, better conforming to the cylindrical object. This facilitates gripping and handling of cylindrical objects during transport, preventing them from falling off.

[0004] However, during use, the aforementioned robotic arm gripper may rotate from a vertical to a horizontal position due to gravity, making it impossible for the curved plate to clamp the workpiece. Utility Model Content

[0020] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0021] Please see Figure 1-3 This utility model provides a technical solution: a mechanical gripping mechanism for plastic edible oil packaging bottle preforms, including a vertical beam 1 with a hollow cavity, a fixed frame 11 on the rear side of the vertical beam 1, and a packaging bottle 7 below the vertical beam 1. A first fixed shaft 2 and a second fixed shaft 4 are fixedly installed on the inner wall of the hollow cavity. A first swing arm 3 is rotatably installed on the outer wall of the first fixed shaft 2, and a second swing arm 5 is rotatably installed on the outer wall of the second fixed shaft 4. A clamping plate 6 is hinged to one end of the first swing arm 3 and one end of the second swing arm 5, which can drive the clamping plate 6 to always be vertically set, preventing the angle of use of the clamping plate 6 from tilting, and can effectively clamp the packaging bottle 7. It also includes a driving unit in the hollow cavity, which drives the first swing arm 3, the second swing arm 5, and the clamping plate 6 to rotate. A moving unit installed on the vertical beam 1 and the fixed frame 11 drives the vertical beam 1 to reciprocate left and right on the front side of the fixed frame 11.

[0022] Furthermore, there are two of each of the first fixed shaft 2, the first swing arm 3, the second fixed shaft 4, and the second swing arm 5, which are arranged symmetrically front to back.

[0023] Furthermore, the drive unit includes an electric telescopic rod 8, a rack 9, and a gear 10. The electric telescopic rod 8 is fixedly installed on the top of the hollow cavity, the rack 9 is fixedly installed on the free end of the electric telescopic rod 8, and there are two gears 10, which are respectively fixedly installed on the outer wall of the first swing arm 3. Both gears 10 mesh with the rack 9.

[0024] Furthermore, the moving unit includes a guide rod 12, a reciprocating screw 13, and a motor 14. The guide rod 12 is fixedly installed on both sides of the vertical beam 1, the reciprocating screw 13 is rotatably installed on both sides of the vertical beam 1, and the motor 14 is fixedly installed on the outer wall of the other side of the vertical beam 1. The output shaft of the motor 14 is fixedly installed on one end of the reciprocating screw 13. The vertical beam 1 is threaded onto the reciprocating screw 13 and slidably installed on the guide rod 12. When the motor 14 is started, the output shaft of the motor 14 drives the reciprocating screw 13 to rotate. The rotation of the reciprocating screw 13 drives the vertical beam 1 to reciprocate left and right on the front side of the fixed frame 11.

[0025] Furthermore, movable openings are provided on the front and rear sides of the hollow cavity, and the first swing arm 3 and the second fixed shaft 4 are movably installed in the movable openings.

[0026] Furthermore, a control button A15 is fixedly installed on one side of the fixing frame 11, and a control button B16 is fixedly installed on the other side of the fixing frame 11. The control buttons A15 and B16 are located between the guide rod 12 and the reciprocating screw 13. When the vertical beam 1 moves to the leftmost position, the vertical beam 1 will press the control button A15, which will activate the electric telescopic rod 8, causing the free end of the electric telescopic rod 8 to drive the rack 9 to rise. The rise of the rack 9 will drive the two first swing arms 3, the second swing arm 5, and the clamping plate 6 to rotate, so that the two clamping plates 6 clamp and fix the packaging bottle 7. When the vertical beam 1 moves to the rightmost position, the vertical beam 1 will press the control button B16, which will activate the electric telescopic rod 8, causing the free end of the electric telescopic rod 8 to drive the rack 9 to fall. The fall of the rack 9 will drive the two first swing arms 3, the second swing arm 5, and the clamping plate 6 to rotate in the opposite direction, so that the two clamping plates 6 separate from the packaging bottle 7, thus unloading the packaging bottle 7.

[0027] Furthermore, an anti-slip pad is provided on one side of the clamping plate 6, which increases the friction with the packaging bottle 7, reduces the risk of the packaging bottle 7 falling, and improves the safety of the gripping mechanism.

[0028] Working principle: By starting the motor 14, the output shaft of the motor 14 drives the reciprocating screw 13 to rotate. The rotation of the reciprocating screw 13 drives the vertical beam 1 to move back and forth on the front side of the fixed frame 11. When the vertical beam 1 moves to the leftmost side, the vertical beam 1 will press the control button A15. The control button A15 will activate the electric telescopic rod 8, which will drive the free end of the electric telescopic rod 8 to drive the rack 9 to rise. The rise of the rack 9 will drive the two first swing arms 3, the second swing arm 5, and the clamping plate 6 to rotate, so that the two clamping plates 6 clamp and fix the packaging bottle 7. When the vertical beam 1 moves to the rightmost side, the vertical beam 1 will press the control button B16. The control button B16 will activate the electric telescopic rod 8, which will drive the free end of the electric telescopic rod 8 to drive the rack 9 to fall. The fall of the rack 9 will drive the two first swing arms 3, the second swing arm 5, and the clamping plate 6 to rotate in the opposite direction, so that the two clamping plates 6 separate from the packaging bottle 7, and the packaging bottle 7 is unloaded.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
