Cutting Corrugated Plastic The invention relates to a mechanical device used for opening a groove outside the trough of a plastic corrugated pipe in a circumferential direction, in particular, it does not need any electrical and electronic induction control system, Cutting Corrugated Plastic only through the mechanism of its own transmission mechanism can be very accurate positioning, strict guarantee that the opening of each slot is located in the corrugated pipe trough in the middle of the slotting machine.
Background technology at present, the well-known plastic corrugated pipe slotting machine consists of several groups of cutting saws located on the same circumference, Cutting Corrugated Plastic the cutting saws of some groups are driven by a plurality of pull rods to the center direction or exit, the several levers are hinged together and driven by the same cylinder, so each cutting saw group always synchronizes with the central direction or exits. Every feed to the plastic corrugated pipe in the direction of the circumference of the outer circle of the groove, the circumference of the number of slots and cutting saw the same number, Cutting Corrugated Plastic The number of axial slots is consistent with the number of saw blades on the cutting saw, and the distance between each of the two saw blades is consistent with the pitch of the corrugated plastic pipe, and the first knife of a plastic corrugated pipe is first cut before each slotted. Let saw blade and tube trough of the center of the Groove, Cutting Corrugated Plastic in the second knife, through the traction machine plastic corrugated pipe forward, the distance through the photoelectric induction switch to the plastic corrugated pipe trough induction count to achieve, to ensure that the whole plastic corrugated pipe continuous slotting, Due to the transmission error and movement inertia of the conveyor, coupled with photoelectric induction switch induction counting errors often cause a large deviation in the slot position, Cutting Corrugated Plastic so that the slot position can not be located in the middle of plastic corrugated pipe trough or even open the groove in plastic corrugated pipe crest, resulting in a large number of plastic corrugated pipe scrap.
In order to overcome the existing shortage of plastic corrugated pipe slotting machine in use, the invention provides a worm-type plastic corrugated pipe slotting machine, Cutting Corrugated Plastic the worm-type plastic corrugated pipe slotting machine does not need any pipe conveying device and photoelectric inductive switch inductive counting system, through the worm curve fixed on the slotting knife rod and the wave meshing of the plastic corrugated pipe to realize the function of conveying the plastic corrugated pipe, the trough of the plastic corrugated pipe is opened through the a alloy cutters installed at the end of the worm curve. Cutting Corrugated Plastic The mechanical structure is very simple, the machine volume and the cost greatly reduces, completes omits the independent pipe conveyer and the electrical and electronic induction control system, the slotting position is very accurate, the slotting quality greatly enhances, greatly reduces the scrap rate and the slotting efficiency. The technical scheme of the invention solves its technical problem is that the function of conveying plastic corrugated pipe is accomplished by the worm curve fixed on the slotting knife rod, and the function of cutting grooving is realized by a alloy cutters installed at the end of the worm curve, if you need to open N-groove in the circumferential direction of the material corrugated pipe, the pitch of the worm curve is designed as plastic corrugated pipe crest pitch N-1 N times, the worm curve is meshed with the wave crest of plastic corrugated pipe, and when the cutter is rotated one weeks, Cutting Corrugated Plastic Plastic corrugated pipe In the worm curve driven forward a pitch, that is, plastic corrugated pipe from the current trough forward to the next trough, installed at the end of the worm curve of the alloy knife head to the current trough trough once, the alloy knife head installed at the end of the worm curve is perpendicular to the axis of the plastic corrugated pipe to ensure that the blade is not axially moved in the cutting section of the plastic corrugated pipe, Cutting Corrugated Plastic and with the rotation of the cutter rod, the plastic corrugated pipe continuously produces an axis movement, and the blade is slotted on each trough. In the plastic corrugated pipe in the circumferential direction of the N-Groove need to be located in the same central line of the pipe, n sets of knives, in order to prevent the plastic corrugated pipe rotation, half of the worm on the knife bar
The 3 line makes a positive spin, Cutting Corrugated Plastic and the other half of the worm curve is made into a reverse. The invention has the advantages of simple structure, convenient manufacture and low cost, and the electronic and electrical control system without any external conveying device can make the slot position accurate positioning, the slotting quality is high, the production efficiency is greatly improved, and the scrap rate of the product is greatly reduced.
