All of the above components constitute the "a grip for pulling and carrying soft and fragile sticky paper" jaw portion.
Description of the motion mode:
the clamp used for dragging and carrying the soft and fragile sticky paper of the invention can be selected according to different working conditions of practical use: the upper jaw is fixed and the lower jaw is fixed and the upper jaw is movable, or the upper jaw and the lower jaw are movable together. The final objective is to bring the lower surface of the upper jaw portion and the upper surface of the lower jaw portion together.
The invention relates to a gripper for dragging and carrying soft and fragile sticky paper, which is driven by an upper jaw and a lower jaw according to different working conditions of actual use, and can be selected as follows: cylinder drive, motor drive, or even spring drive.
Working mode-clamping:
when the paper needs to be clamped, the soft and fragile adhesive paper is moved into the space between the upper jaw and the lower jaw of the clamp claw, and the upper jaw and the lower jaw are reasonably closed by a certain driving mode. When the upper jaw and the lower jaw are folded, the anti-sticking films of the upper jaw and the lower jaw can be in direct contact with the paper, so that the force is further transmitted to the inside, and the buffering cotton inside the paper is elastically deformed. The deformation of the buffer cotton absorbs a part of the clamping force and makes the clamping force distributed evenly. So that the soft and fragile paper can not be broken and deformed. Meanwhile, the anti-sticking film formed by weaving the polytetrafluoroethylene filaments on the outer layer is also deformed due to the action of the buffer cotton wrapped in the anti-sticking film, and then warp and weft which are woven can slightly move.
The clamp grabs the bracket, the lining plate, the air plate and the like of the upper jaw and the lower jaw, and provides good rigid support for the upper jaw and the lower jaw.
At the moment, after the paper is clamped, the excellent clamping effect can be obtained by adjusting the external drive and the movement distance of the upper jaw and the lower jaw.
Working mode-separation:
when the paper is moved to a preset position, the upper jaw and the lower jaw are separated by a certain driving mode, and the paper is separated:
the clamp grabs the bracket, the lining plate, the air plate and the like of the upper jaw and the lower jaw, and provides good rigid support for the upper jaw and the lower jaw.
During the separation, with the antiseized membrane of the fragile viscidity paper direct contact of softness, can effectually prevent that the paper from gluing and grabbing jaw contact surface about pressing from both sides.
Meanwhile, the compressed buffer cotton can recover deformation, so that the anti-sticking film formed by weaving polytetrafluoroethylene filaments coated on the outer layer of the buffer cotton also recovers deformation, and the warp and weft which are woven can slightly move. The process is equivalent to that the anti-sticking film and the soft fragile sticky paper generate relative displacement, and the paper is further prevented from being stuck on the contact surface of the upper jaw and the lower jaw of the clamp.
An air passage is reserved between the upper jaw and the lower jaw, and air holes are reserved on the lower surface of the upper jaw and the upper surface of the lower jaw. The air joints are left at the tails of the upper jaw support and the lower jaw support, and when the upper jaw and the lower jaw are separated, the air joints are controlled by the outside to inflate the upper jaw and the lower jaw. For the upper jaw, high-pressure gas can sequentially pass through an upper jaw air connector, an air passage in an upper jaw support, an air passage of an upper jaw air plate, an air hole of the upper jaw air plate, a long runner hole of an upper jaw buffer surface and a long runner hole of an upper jaw anti-sticking film to be blown on paper to assist the paper to be separated. For the lower jaw, high-pressure gas can sequentially pass through the lower jaw air connector, the air channel in the lower jaw support, the air channel of the lower jaw air plate, the air hole of the lower jaw air plate, the long runner hole of the lower jaw buffer surface and the long runner hole of the lower jaw anti-sticking film, and the high-pressure gas is blown on paper to assist the paper to be separated. The beat of air blowing is that continuous air blowing and pulse air blowing are combined, the continuous air blowing can separate large-area adhesion, and the pulse air blowing can separate small-area adhesion. The upper jaw sealing gasket and the lower jaw sealing gasket can be effectively guaranteed, compressed gas can flow to the air hole from the air joint, and air leakage is avoided.
Due to the three anti-sticking means and reasonable air flow control, the paper can be effectively prevented from being stuck on the clamp claw and not separated after being dragged and conveyed.
Details not described in the present specification belong to the prior art known to those skilled in the art.
