Specifically, the turntable is provided with a central guide hole through the plastic tube, a disk with the turntable is connected to the guide mechanism, and the rotary table of the relief portion of the turntable plastic tube a plastic tube communicated via the other guide means turntable rotatably provided on the heating frame, guide means to follow the turntable is rotated together with the plastic pipe is heated through the turntable on the chassis via a plastic tube 4 and then through the heating means, the heating means completion of knitting of four pairs of plastic heating the guard band on the tube, so that the protective tape is firmly bonded to the plastic tube, to form a composite plastic pipe, the heating means 4 is located next station the traction means pulling the finished composite plastic pipe forward.
[0040]Wherein the rotation table 105 is provided on the adjustment plate 106 with a support shaft, the support shaft 106 of the adjustment plate 108 is provided with a first servo motor, the output shaft of the first servo motor 108 is provided with a first drive gear 109, the support shaft 106 is rotatably connected to the support shaft 106 adjusting plate, a lower end of the support shaft 106 is provided with a first driven gear 109 with the first driving gear 110 engaged, the support shaft 106 is detachably provided on the guard band reel 107.
[0041] Wherein said support plate is provided with adjustment shaft 106 adjusting air cylinder 111, the support shaft 106 to the rotation angle between the adjustable table 105. By setting the inclination angle of the support shaft is adjustable in the translational mount the reset process can effect the guard band is wound on a plastic tube to maintain a good consistency, the guard band to prevent overstretching or not tight wrapping.
[0042] Wherein said heating cylinder 202 has a socket opening ring compaction, the compactor is provided with a ring coaxial with the second driven gear 205, the heating cartridge 202 is provided with a second side of the servo motor 203, the a second output shaft of the servo motor 203 is provided with a second drive gear 205 engages second driven gear 204, the compactor is provided with a first lateral end surface of the ring a plurality of guide rollers 207 and staggered longitudinal compaction roller 208.
[0043] Wherein the plastic tube 5 has openings at both ends of the relief portion of the plastic tube 5 for assisting the forward second transverse guide roller 112.
[0044] Wherein the plastic tube 5 is a thermoplastic plastic tube 5, the guard band is a fiberglass tape.
[0045] Wherein the guard band and the plastic tube 5 is bonded to one surface provided with an adhesive layer.
[0046] Wherein the plastic tube relief portion positioned intermediate position of the rotating table, said support shaft portion surrounds the circumference of the plastic tube distributed uniformly relief, the relief portion is a plastic tube escape hole, the escape hole is embedded an annular blow blowing nozzle means, blowing means blowing means arranged uniformly around, by providing the blowing means, before the plastic tube and the guard bands are combined, may be present on the plastic tube to blow off dust and other impurities, prevent the influence of large particulate matter in combination with plastic pipes and protective effect.
[0047] Kind knitting machine use the pipe, comprising the steps of:
[0048] S1: The guard band 107 is mounted on the reel support shaft 106, a support in which the start end 106 of the guard band on the plastic tube 5 is fixed to the shaft;
[0049] S2: start the turntable 105 is rotated, the guard band around the circumference of the plastic tube 5 is woven, spirally formed on an outer guard band woven plastic tube 5;
[0050] S3: In the same protection when the support shaft 106 on the tape is used up, controlling the rotating table 105 stops rotating, the translation start base 3, so that the base pan 3 is wound on the chassis 101 and the plastic tube 5 from the initial position in the speed of movement of said base, so that the rotating table 105 remains stationary relative to the plastic pipe in the forward direction 5 5 plastic tubes;
[0051] S4: The start end of the guard band on the other reel support shaft 106 and has run out of the unused guard band at the end of the braided tube is joined, at the same time has run out reel support shaft 106 where the replacement of the protective tape disk 107;
[0052] S5: Start of the turn table 105 continues to rotate, while the base 3 along the translational start step S3 in the opposite direction thereof is reset to the initial position, this time to enhance the speed of rotation of the table 105, the translation reset to its initial base 3 stop position after the movement, when the rotation speed table 105 is returned to normal speed.
[0053] S6: Repeat steps S3 to S5 sequentially until it is completed.
[0054] Wherein, in step S5, the translating base which is reset in the opposite direction to the initial position in step S3, the period of the rotation speed of the raising table, said translating chassis is reset to the initial position after the movement stops, the rotational speed of the rotary table at this time recovery to normal speed.
[0055] So that when changing the guard band knitting of the machine for the plastic tube 5 a braided portion of the plastic pipe 5 remains relatively stationary, commutation zone, without the plastic tube 5 production equipment and the traction equipment downtime, complete movement changer, greatly improve the production efficiency, and may be knitted on the braided tube of any length.
[0056] It is located adjacent the machine knitting a plastic pipe production station and the adjacent next station equipment plastic tube changer when the traction mechanism are performed without stopping, to avoid repeated plastic pipe production equipment downtime opportunity to open resulting in production of the diameter plastic pipe bend or deviation occurs in the engagement portion of the stop and start.
[0057] The above is merely examples and descriptions of the structure of the present invention, and those skilled in the art will do a wide variety of modifications or supplements or use in a similar manner, as long as they do not deviate from the structure of the invention. Or Beyond the scope defined by the claims, it should belong to the scope of the present invention.
