The relatively difficult problem of removal.
The anti-theft ring removal device for plastic bottle in this programme, including support, support are provided with clamping device, clamping
Mechanism includes left grip block and right grip block, and left grip block is connected with bracket slide, and right grip block is provided with location hole, right clamping
Cutting mechanism is provided with the right side of plate, cutting mechanism includes link, and link is fixedly connected with right grip block, and link is provided with
Cylinder-shaped sleeve, sleeve pipe is coaxially disposed with location hole, and sleeve pipe is slidably connected along the axis direction of location hole with link, in sleeve pipe
At least 4 cutting knifes are provided with, cutting knife is located at sleeve pipe near the end of right grip block, and 4 cutting knife axles centered on the axis of sleeve pipe are in
Annular array is distributed, and towards right grip block, cutting knife is fixedly connected the blade part of cutting knife with sleeve pipe, is fixedly connected with sleeve pipe driven
Gear, support is provided with rotating shaft, and the driving gear coordinated with driven gear is fixedly connected with rotating shaft, and rotating shaft is provided with screw thread
Section, is provided with movable block at thread segment, movable block coordinates with thread segment screw thread, and movable block is connected with bracket slide, is set on movable block
There are the cutter for cutting plastic bottle body, support is provided with the drive mechanism of drive sleeve movement, and sleeve pipe turns with drive mechanism
Dynamic connection, support is provided with the motor of drive shaft rotation.
Left grip block and right grip block are set, for gripping plastic bottle.Location hole is set, for the bottle for plastic bottle
Mouth section is through location hole and is positioned.Sleeve pipe is set, for fixed cutting tool.Cutting knife is set, for cutting bottleneck, meanwhile, lead to
The rotation of sleeve pipe is crossed, cutting knife is extruded the bottleneck being cut.Driven gear is set, for driving sleeve pipe to rotate.Rotating shaft is set, is used
Rotated in drive driving gear, meanwhile, the thread segment of rotating shaft drives movable block movement.
Operation principle:Plastic bottle is placed on clamping device, the pass of plastic bottle is passed through determining on right grip block
Position hole, the left grip block of movement fixes bottle;Control drive mechanism promotes sleeve pipe dynamic toward mouth cylindrical part displacement, cutting knife is cut bottle
Mouthful, so that bottleneck is cut into some pieces, rotating shaft makes rotating shaft drive driving gear to rotate, and driving gear is by driven
Gear driven sleeve pipe is rotated, so that cutting knife promotes the bottleneck position after cutting to be moved to the axis direction of sleeve pipe, forms one
Cone structure, so that anti-theft ring slides;The rotation of rotating shaft drives movable block movement, so that movable block drives cutter by modeling
Material bottle is scratched.
Compared with prior art, the advantage of this programme is:1st, bottleneck is cut by the cutting knife on sleeve pipe, is then rotated,
The diminution of bottleneck is set to form tapered shape, so that what anti-theft ring can be complete removes.2nd, sleeve pipe rotate while, movable block
Also move, bottle is scratched, so that the label fracture on bottle, convenient to remove label.3rd, cutting knife is cut when bottle is cut
Rotation of the knife to bottle play restriction effect, so that when the rotation of sleeve pipe drives cutting knife extruding mouth cylindrical part, it is to avoid bottle turns
It is dynamic.
Further, the cutting knife is 6.Cutting knife is set to 6, makes cutting knife that bottleneck is cut into 6 pieces, so that each
The Area comparison of block is small, facilitates sleeve pipe to be twisted when rotating;6 cutting knifes are set, the distance between cutting knife is unlikely to too small,
It is convenient that cutting knife is installed.
Further, the junction rounding of the cutting knife and sleeve pipe.Reduce the stress concentration of cutting knife and cannula connection.
Further, the drive mechanism is hydraulic cylinder.Conveniently it is controlled, while mitigating the work burden of workman.
Further, the cutter are slidably connected with movable block, and movable block is provided with the limit for fixed cutting cutter position
Position bar.In fixed plastics bottle, by the way that first cutter are retracted, after plastic bottle is fixed, then cutter are promoted to puncture modeling
Material bottle, so that convenient be fixed to plastic bottle, it is to avoid influence of the cutter to plastic bottle position in fixed plastics bottle.
Specific embodiment
Below by specific embodiment, the present invention is further detailed explanation:
Reference in Figure of description includes:Motor 1, left grip block 21, cutter 31, movable block 32, rotating shaft 33, right folder
Hold plate 22, sleeve pipe 41, driven gear 42, link 43, hydraulic cylinder 44, driving gear 34, support 5, cutting knife 45.
The anti-theft ring removal device for plastic bottle as depicted in figs. 1 and 2, including support 5, support 5 are provided with clamping
Mechanism, clamping device includes left grip block 21 and right grip block 22, and left grip block 21 is slidably connected with support 5, right grip block 22
It is bolted with support 5.Right grip block 22 is provided with location hole, and when fixed, the mouth cylindrical part of plastic bottle is passed through plastic bottle
Location hole is simultaneously fixed.The right side of right grip block 22 is welded with link 43, and link 43 is provided with the cylinder of horizontally set
Shape sleeve pipe 41, sleeve pipe 41 is coaxial with location hole and is slidably connected with link 43.The inside of sleeve pipe 41 is provided with 6 cutting knifes 45, cuts
