[0002] At present, a Chinese patent with the announcement number CN216579154U discloses a feeding device of a bottle blowing machine, which includes a transverse movement mechanism, a lifting mechanism, a flipping mechanism, and a clamping mechanism. The transverse movement mechanism includes a base plate seat, a sliding plate seat arranged on the base plate seat, and a transverse movement driving unit, and the transverse movement driving unit is used to drive the base plate seat to move transversely along the Y axis. The lifting mechanism includes a lifting plate seat, a lifting driving unit installed on the lifting plate seat, and the lifting driving unit is used to drive the lifting plate seat to rise and fall along the Z axis. The flipping mechanism includes a flipping seat, and a flipping driving unit installed on the flipping seat, and the flipping seat is provided with a connecting end and a free end, and the connecting end is provided with a rotation axis extending along the X axis, and the flipping driving unit is connected to the free end to drive the free end to flip around the rotation axis. The clamping mechanism includes a bottle blank grasping member, and the bottle blank grasping member is installed at the free end, and a bottle picking position and a bottle placing position are provided on the movement path of the bottle blank grasping member.

[0003] When it is necessary to take the bottle, the transverse driving unit drives the sliding plate seat to move to one side of the conveying channel of the bottle blowing machine, drives the bottle blank grabbing member to move transversely to the bottle taking position, grabs the bottle through the bottle blank grabbing member, and then the lifting driving unit drives the lifting plate seat to move upward, the bottle blank grabbing member drives the bottle to be taken out from the conveying channel, the transverse driving unit drives the sliding plate seat to move back, the flipping driving unit drives the bottle blank grabbing member to flip through the flipping seat, the lifting driving unit drives the lifting plate seat to move downward, drives the bottle blank grabbing member to move downward to the bottle placing position, and then the bottle blank grabbing member releases the bottle and places the bottle in the set work station, and the flipping driving unit drives the flipping seat to return to its original position.

[0004] However, during the bottle taking process, the lifting drive unit needs to be frequently used to drive the lifting seat to move up and down, which reduces the unloading efficiency of the unloading device to a certain extent. Summary of the invention

[0005] In view of this, an object of the present invention is to provide a material unloading robot for a bottle blowing machine, which has the advantage of high material unloading efficiency.

[0006] In order to solve the above technical problems, the technical solution of the present invention is: a blanking robot for a bottle blowing machine, comprising a base, two hinged seats symmetrically arranged on the top of the base, a rotating shaft rotatably connected between the two hinged seats, a rotating cylinder fixedly connected to the side of the bracket to drive the rotating shaft, and a plurality of clamping mechanisms evenly arranged on the rotating shaft along the axial direction; the clamping mechanism comprises a clamping claw cylinder, two positioning seats respectively arranged at the two output ends of the clamping claw cylinder, a clamping cavity is formed between the two positioning seats, a guiding inclined surface is arranged on the positioning seat near the clamping cavity, an oblique guiding groove is opened on the guiding inclined surface, the oblique guiding groove extends in a direction parallel to the guiding inclined surface, a guide slider is slidably arranged in the oblique guiding groove, and a clamping block is arranged at the end of the guide slider protruding from the oblique guide groove.

[0007] Through the above technical solution, when a bottle blank is blown into a bottle body by a bottle blowing machine, the rotating shaft is driven to rotate circumferentially by a rotating cylinder, so that the clamping mechanism turns to the side of the bottle blowing machine. When the two clamping blocks move to the two sides of the bottle body, the two clamping blocks are driven to approach each other by the clamping claw cylinder. After the two clamping blocks are respectively in contact with the two sides of the bottle body, the two clamping blocks move upward along the oblique guide groove under the action of the clamping cylinder to remove the bottle body from the bottle blank seat. When the bottle body is separated from the bottle blank seat, the rotating shaft is driven to rotate circumferentially by a rotating cylinder, so that the clamping mechanism turns away from the bottle blowing machine. When the bottle body moves to the side where the manipulator is away from the bottle blowing machine, the two clamping blocks are controlled to move away from each other by the clamping claw cylinder. When the clamping block is separated from the bottle body, the bottle body falls.

[0008] When the above-mentioned unloading robot is used to take bottles, there is no need to use a lifting drive unit to drive the base to move up and down, so the time required for unloading is shorter and the unloading efficiency is higher.
