Description

Technical Field

[0001] This utility model relates to the field of plastic bottle production technology, specifically to a rotatable cylinder gripper. Background Technology

[0002] Plastic bottles are mainly made of materials such as polyethylene or polypropylene with the addition of various organic solvents. After the addition of the corresponding organic solvents, the plastic containers are formed by blow molding, extrusion blow molding, or injection molding through plastic molds after being heated at high temperature.

[0003] When 5L plastic bottles are demolded and transported after injection molding, they are transferred by a robotic arm. However, the robotic arm currently used to pick up the product uses a three-jaw jack to insert into the bottle mouth and then open it. However, the bottle mouth is hot when it is newly formed, and it is easy to deform during the gripping process.

[0004] There is an urgent need for a rotatable cylinder gripper to address the technical deficiencies mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a rotatable cylinder gripper to solve the problem of easy deformation during gripping mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rotatable cylinder gripper, including a mounting base, a stepper motor fixedly mounted at the bottom end of the mounting base, a fixed plate mounted at the output end of the stepper motor, a support slide rail fixedly connected at the bottom end of the fixed plate, an adjusting screw movably connected inside the support slide rail, two sets of screw sleeves threaded onto the external thread of the adjusting screw, a drive motor fixedly mounted on the right side of the support slide rail, a clamping cylinder fixedly connected at the bottom end of the screw sleeves, a gripper connecting rod movably connected at the output end of the clamping cylinder, a connecting seat fixedly connected at the end of the gripper connecting rod, a gripper body detachably mounted on the connecting seat, a distance sensor fixedly mounted at the middle position of the bottom end of the support slide rail, and a limit rod fixedly connected to the bottom end inside the support slide rail.

[0007] As a further technical solution of this utility model, the stepper motor, drive motor, clamping cylinder and distance sensor are all externally connected to a controller.

[0008] As a further technical solution of this utility model, the adjusting screw is provided with two sets of opposite threads on its outside, and the bottom end of the screw sleeve is slidably connected to the outside of the limiting rod.

[0009] As a further technical solution of this utility model, a fixed base is fixedly connected to the middle position of the top of the fixed plate, and the output end of the stepper motor is fixedly connected to the fixed base.

[0010] As a further technical solution of this utility model, the gripper body is arc-shaped, and a silicone pad is fixedly connected to the inner side of the gripper body.

[0011] As a further technical solution of this utility model, the front end of the connecting seat is provided with a mounting bolt, and the top end of the gripper body is embedded in the interior of the connecting seat and connected by the mounting bolt in a threaded manner.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the rotatable cylinder gripper not only realizes the function of easy and stable gripping and flexible gripping, but also realizes the function of easy disassembly and replacement.

[0013] (1) By setting up a clamping cylinder, a clamping linkage, a clamping body and a silicone pad, the clamping cylinder can push the clamping linkage to adjust the clamping angle. The clamping body on the clamping linkage adopts an arc-shaped structure. After the two sets of clamping bodies are combined, they can fit the handle of the plastic bottle for stable gripping. The silicone pad on the inner side of the clamping body can enhance the friction of the clamping, effectively preventing the plastic bottle from deforming. This structure achieves the function of stable and efficient gripping.

[0014] (2) By setting a stepper motor, a support slide rail, an adjusting screw, a distance sensor, a drive motor and a screw sleeve, the two sets of cylinder grippers can adjust the gripping distance according to the gripping requirements. During adjustment, the drive motor drives the adjusting screw to rotate, and the screw sleeve outside the adjusting screw drives the gripping cylinder to move. The distance sensor can accurately measure the distance of the gripping cylinder. After gripping, the stepper motor can drive the cylinder grippers to rotate to adjust the gripping position. Multiple spacing and angle adjustments can improve the gripping range of the grippers and enhance the gripping flexibility.

[0015] (3) By setting up a gripper body, gripper connecting rod, connecting seat and mounting bolt, the shape and size of the gripper body can be changed according to the processing requirements. When changing, the gripper body is removed from the gripper connecting rod. When disassembling, first unscrew the mounting bolt, and then pull down the gripper body to move it out of the connecting seat for replacement. This structure realizes the function of easy disassembly and replacement, and improves the flexibility of cylinder gripper gripping. Attached Figure Description

During adjustment, the drive motor 11 drives the adjusting screw 5 to rotate, and the screw sleeve 12 outside the adjusting screw 5 drives the gripping cylinder 6 to move.

After gripping, the stepper motor 2 can drive the cylinder gripper to rotate to adjust the gripping position.

[0027] The front end of the connector 10 is provided with a mounting bolt 15, and the top end of the gripper body 8 is embedded in the interior of the connector 10 and is threadedly connected by the mounting bolt 15.

After the two sets of gripper bodies 8 are combined, they can fit snugly against the handle of the plastic bottle for stable gripping. The silicone pad 9 on the inner side of the gripper body 8 can enhance the gripping friction and effectively prevent the plastic bottle from deforming. The shape and size of the gripper body 8 can be changed according to processing requirements. When changing, the gripper body 8... Remove the gripper from the connecting rod 7. To disassemble, first unscrew the mounting bolt 15, then pull down the gripper body 8 to remove it from the connecting seat 10 for replacement. The two sets of cylinder grippers can adjust the gripping distance according to the gripping requirements. During adjustment, the drive motor 11 drives the adjusting screw 5 to rotate, and the screw sleeve 12 outside the adjusting screw 5 drives the gripping cylinder 6 to move. The distance sensor 13 can accurately measure the distance of the gripping cylinder 6. After gripping, the stepper motor 2 can drive the cylinder gripper to rotate and adjust the gripping position.
