Description

Technical Field

[0001] The utility model relates to the technical field of packaging bag printing, in particular to a reeling and unreeling mechanism for printing plastic packaging bags. Background Art

[0002] Plastic packaging bags are made of plastic as raw material and are used to produce various daily necessities. They are widely used in daily life and industrial production. When producing plastic packaging bags, the printing process is also a very important step. At present, plastic packaging bags are printed by printing. The packaging bags to be printed are sent into the printing machine body through multiple conveyor rollers for printing. When the printing machine is printing plastic packaging tapes, a detachable winding rod is usually used to clamp the paper tube of the plastic packaging bag roll. Then the winding rod with the plastic packaging bag roll is clamped at the unwinding turntable of the printing machine, and then the plastic packaging tape roll is released from the paper tube with the help of the traction structure of the printing machine, and the reel end at the other end of the printing machine uses the reel driven by the motor to clamp the paper tube to reel in the plastic bag.

[0003] At present, when plastic packaging bags are rolled up and unrolled during printing, a special reel is usually driven by a motor to continuously collect or unroll the plastic packaging bags during printing. The reel for rolling up and unrolling is usually driven by a gear structure matched with a motor with a gear at one end of the rod body. When the reel is clamped with a paper roll for rolling up and unrolling the plastic packaging bags for rolling up and unrolling, a counter plate symmetrically clamped into the paper roll is usually installed with bolts outside the rod body of the reel to assist the paper roll to rotate when rolling up and unrolling the plastic packaging bags. When workers disassemble the rolled up and unrolled paper roll for replacement, they need to disassemble the counter plate and fixing bolts at the reel, which makes the paper roll replacement efficiency low when rolling up and unrolling the plastic packaging bags at the reel. For this reason, we propose a reeling and unrolling mechanism for plastic packaging bag printing. Utility Model Content

[0004] The main purpose of the utility model is to provide a winding and unwinding mechanism for printing plastic packaging bags. The winding rod of the packaging bag printing machine is improved so that the winding rod is split into a winding rod with a transmission gear, a disassembling rod of a rod disassembling mechanism and a rotating rod for use as the winding and unwinding mechanism. After the disassembled winding rod is clamped and installed with the disassembling rod, there is a clamping structure at the disassembling rod and the rotating rod that can be pulled contracted or ejected by drawing a rope, so that it is convenient to disassemble the rod body at the winding rod of the packaging bag printing machine to take out the paper tube for winding and releasing the plastic packaging bag. Compared with the disassembly structure of the original winding rod and the abutment plate of the packaging bag printing machine in which the paper tube is locked and pressed with bolts, the winding rod of the utility model is more convenient for disassembling the plastic packaging bag and retracting the paper tube, and can effectively solve the problems in the background technology.

[0009] Furthermore, the groove body of the T-shaped groove is clamped with an inner stop plate larger than its own groove opening, and a U-shaped lining plate welded on the surface of the inner stop plate extends out of the small groove opening of the T-shaped groove;

[0013] Furthermore, a mounting hole is provided on the end surface of the split rod between the T-shaped groove and the core hole, a mounting hole is provided on the rod body surface of the rotating rod, and a long screw is screwed between the mounting holes of the rotating rod and the split rod;

[0014] By adopting the above technical solution, the split rod and the rotating rod can be locked and installed with the installation hole by means of a long screw.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] The utility model improves the winding rod of the packaging bag printing machine, so that the winding rod with a transmission gear, a detaching rod of a detaching rod mechanism and a rotating rod are separated and used as a winding and unwinding mechanism. After the detached winding rod is clamped and assembled with the detaching rod, there are clamping structures at the detaching rod and the rotating rod that can be pulled by a drawstring to shrink or pop out, so that it is convenient to detach the rod body at the winding rod of the packaging bag printing machine to take out the paper tube for collecting and releasing the plastic packaging bag.

[0019] Compared with the disassembly and assembly structure of the original rolling rod and the abutting plate of the packaging bag printing machine, which cooperate with the bolts to lock and press against the paper tube, the rolling rod of the utility model is more convenient when disassembling and assembling the plastic packaging bag and storing the paper tube.
