Description

Clamping and transferring mechanism of bag feeding type packaging machine Technical Field The utility model relates to a packaging machine, in particular to a clamping and transferring mechanism of a bag feeding type packaging machine. Background The bag feeding type packaging machine is a device for carrying out vacuumizing and heat sealing after packaging bags are filled. The working principle of the automatic vacuum packaging machine is that empty packaging bags are clamped through clamping jaws on a rotary table, the packaging bags are driven to a bag opening and loading station through the rotary table, then the rotary table drives the packaging bags to be conveyed to a clamping and transferring mechanism, the clamping and transferring mechanism clamps the packaging bags, the clamping jaws on the rotary table loosen the packaging, and a follow-up clamping and transferring mechanism drives the packaging bags to be conveyed into a vacuumizing and heat sealing mechanism for follow-up vacuumizing and heat sealing processing. At present, the open-close angles of the clamping claws of the clamping and transferring mechanism on the market are fixed, and in order to ensure that the clamping claws cannot interfere with the structures such as clamping claws on a turntable when clamping packaging bags, the open-close angles of the clamping claws need to be set to be quite large, but when the clamping claws are subsequently transferred into a vacuumizing heat sealing mechanism and the packaging bags are loosened, the clamping claws of the clamping and transferring mechanism possibly collide with other parts when being opened, so that normal work is influenced. Disclosure of utility model In view of the shortcomings of the background art, the technical problem to be solved by the utility model is to provide a clamping and transferring mechanism for a bag feeding type packaging machine. For this purpose, the utility model is realized by adopting the following scheme: The clamping and transferring mechanism of the bag feeding type packaging machine is characterized by comprising a movable frame, the movable frame is connected with a movable driving assembly, a lifting seat is movably arranged on the movable frame, the lifting seat is connected with the movable driving assembly, a first cylinder and a second cylinder are arranged on the lifting seat, the output end of the first cylinder drives a first rotating shaft to rotate through a transmission arm assembly, a first gear and a first clamping plate are connected onto the first rotating shaft, the first gear is meshed with a second gear, the second gear is connected with a second rotating shaft, the second rotating shaft is connected with a second clamping plate, a limiting arm is connected onto the second rotating shaft, a piston rod of the second cylinder can prop against the limiting arm after extending out, and the air pressure in the second cylinder is larger than that in the first cylinder. The movable driving assembly comprises a first motor, the output end of the first motor is connected with a driving screw, the driving screw is in threaded connection with a movable frame, and a guide assembly is arranged corresponding to the movable frame. The lifting driving assembly comprises a third air cylinder, the cylinder body of the third air cylinder is arranged on the movable frame, and a piston rod of the third air cylinder is connected with the lifting seat. The transmission arm assembly comprises a first transmission arm, one end of the first transmission arm is connected with a piston rod of a first cylinder, the other end of the first transmission arm is hinged with one end of a second transmission arm, the other end of the second transmission arm is hinged with one end of a third transmission arm, and the other end of the third transmission arm is connected with a first rotating shaft. Above-mentioned technical scheme's centre gripping transfer mechanism for bag packing machine, through setting up first, the second cylinder, the piston rod of control first cylinder is flexible normally, and through drive arm subassembly and gear train transmission, can drive first, the second splint carry out the opening and shutting of wide-angle, so that carry the wrapping bag on the carousel, when subsequently sending the wrapping bag to evacuation heat-seal mechanism in, can stretch out through the piston rod of control second cylinder, make first, the second splint just can not continue to open when opening to spacing arm and the piston rod of second cylinder offset, realize the narrow-angle opening and shutting of splint, and then avoid splint to collide with the part in the small-size evacuation heat-seal mechanism when loosening the wrapping bag, ensure that equipment can normal operating.
