Cutting Corrugated Plastic The plurality of sets of cutting saws are driven by a plurality of rods to feed or exit in the center direction, and the plurality of rods are connected to each other and are driven by the same cylinder, so that each cutting saw group feeds in the center direction When the exit is always synchronized, Cutting Corrugated Plastic each time the feed is applied, the number of slots in the circumferential direction is the same as the number of the saws, and the number of the slots is the same as that of the cutting saw. The number of saw blades is the same, and the distance between each adjacent two saw blades is the same as that of the plastic corrugated pipe trough. Each time the first knife of a plastic corrugated pipe is grooved, Pipe trough of the center of anastomosis, in the slotted second knife, through the tractor to the plastic corrugated pipe forward delivery, Cutting Corrugated Plastic the transmission distance through the photoelectric sensor switch on the corrugated steel bellows induction count to achieve, to ensure that the whole plastic corrugated The pipe is continuously grooved due to the transmission traction machine with transmission error and motion inertia, coupled with the photoelectric sensor switch induction counting error often caused by slotting production A large deviation, so that the position can not be located in the slotted corrugated plastic pipe and even the central valley of the grooves are opened in peak corrugated plastic pipe, produces a large number of scrap plastic pipe.
In order to overcome the shortcomings of the existing plastic corrugated pipe grooving machine in use, the present invention provides a worm-type plastic corrugated pipe grooving machine which does not require any pipe conveying device and photoelectric induction The switch induction counting system achieves the function of conveying the corrugated pipe by means of the worm curve fixed on the slot knife and the corrugated pipe of the plastic corrugated pipe. The plastic ripple is realized by installing an alloy cutter head at the end of the worm curve The trough of the pipe is grooved, the mechanical structure is very simple, Cutting Corrugated Plastic the volume and cost of the machine are greatly reduced, Cutting Corrugated Plastic and the independent pipe conveying device and the electrical and electronic induction control system are omitted. The slotted position is very accurate and the slot quality is greatly improved, Greatly reducing the waste rate and slotting efficiency. The technical solution adopted by the invention to solve the technical problem is that the function of conveying the plastic corrugated pipe is completed by the worm curve fixed on the slot knife shank; the function of the cutting slot is composed of an alloy cutter head mounted at the end of the worm curve If the need to open the N groove in the circumferential direction of the corrugated pipe, Cutting Corrugated Plastic the pitch of the worm curve is designed to be N-1 / N times the wave pitch of the corrugated pipe. Cutting Corrugated Plastic The worm curve engages with the crest of the corrugated pipe. Rotate for a week, Cutting Corrugated Plastic the plastic corrugated pipe in the worm curve driven by a pitch, that is, Cutting Corrugated Plastic the plastic corrugated pipe from the current trough to the next trough, installed at the end of the worm curve of the alloy head of the current trough slotted, installed in the The edge of the worm curve at the end of the alloy blade perpendicular to the axis of the plastic corrugated pipe to ensure that the blade in the cutting range of plastic corrugated pipe does not move axially, with the rotation of the arbor, plastic corrugated pipe continue to produce axial movement, Cutting Corrugated Plastic the blade for each trough To be slotted one by one. In the circular direction of the plastic corrugated pipe to open the N groove need N group located in the pipe on the same center line of the arbor, Cutting Corrugated Plastic in order to prevent the slot when the plastic corrugated pipe rotation, half of the worm on the worm
3 lines made of positive rotation, the other half of the worm on the worm curve made of anti-rotation. The invention has the advantages that the machine structure is simple, Cutting Corrugated Plastic the manufacturing convenience is convenient, the cost is low, and the electronic control system of the external conveying device is not needed to make the grooving position accurate, the grooving quality is high, the production efficiency is greatly improved, the product is scrapped The rate is greatly reduced.
