Description

Technical Field

[0001] The invention relates to the technical field of plastic corrugated pipe processing, in particular to a high-speed plastic corrugated pipe cutting machine. Background Art

[0002] Plastic bellows are tubular, elastic, and sensitive components made from foldable, corrugated sheets of plastic connected along the folding and expansion directions. There are two types of plastic bellows: completely airtight and watertight, such as those used in propellant delivery for launch vehicles, gas heaters, and water heaters; and continuously wound with strips of material. Conventional wound bellows are used to protect cables, such as in magnetic card telephones and machine tools.

[0003] Before using the plastic corrugated tube, the rolled plastic corrugated tube needs to be cut so that the length and opening of the plastic corrugated tube meet the actual needs. The conventional plastic corrugated tube cutting machine can only cut the corrugated tube according to the set length or can only split the corrugated tube, resulting in a narrow range of use. During the processing of the plastic corrugated tube, it needs to be transferred between multiple machines, resulting in inconvenience in production and low efficiency. In addition, the existing plastic corrugated tube cutting equipment needs to match the specifications (tube diameter) of the corrugated tube together with the conveying device and the limiting device. Therefore, when changing the specifications of the plastic corrugated tube to be cut, multiple components need to be adjusted. The adjustment process is cumbersome and prone to errors.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Summary of the Invention

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] As introduced in the background technology, there are deficiencies in the existing technology. In order to solve the above technical problems, this application proposes a high-speed plastic corrugated tube cutting machine.

[0031] See also Figure 1-Figure 7, a high-speed plastic corrugated pipe cutting machine includes an operating table 1, a cutting mechanism 2 is installed on the front of the operating table 1, a guiding mechanism 3 is provided at the feeding end of the cutting mechanism 2, a collecting mechanism 4 is provided at the discharging end of the cutting mechanism 2, a power input mechanism 5 is further provided between the guiding mechanism 3 and the cutting mechanism 2, and a positioning and correction mechanism 6 is further provided on the outside of the cutting mechanism 2; the cutting mechanism 2 is used to cut the plastic corrugated pipe passing through; the cutting mechanism 2, the power input mechanism 5 and the positioning and correction mechanism 6 have a uniquely determined plastic corrugated pipe conveying path inside, and the plastic corrugated pipe conveying path passes through a uniquely determined horizontal conveying surface; the power input mechanism 5 includes two symmetrically arranged conveying components 51, the two conveying components 51 are always in a symmetrical relationship with respect to the horizontal conveying surface, a synchronous driving mechanism 52 is provided on one side of the two conveying components 51, and a spacing adjustment mechanism 53 is provided on one side of the two conveying components 51; the spacing adjustment mechanism 53 is used to synchronously adjust the distance between the two conveying components 51 and the horizontal conveying surface, and the synchronous driving mechanism 52 is used to synchronously adjust the distance between the two conveying components 51 and the horizontal conveying surface. The two conveying components 51 are driven simultaneously to synchronously start conveying the plastic corrugated pipe; the positioning and correction mechanism 6 includes two symmetrically arranged adjusting wheels 61, each adjusting wheel 61 is provided with several pipe-piercing molds 62 of different specifications, and the two adjusting wheels 61 rotate in opposite directions and at the same angle each time; on the surface of each adjusting wheel 61, the angle ratio between several pipe-piercing molds 62 with increasing specifications and the pipe-piercing mold 62 with the smallest specification is consistent with the specification ratio between several pipe-piercing molds 62 with increasing specifications and the pipe-piercing mold 62 with the smallest specification; after the two adjusting wheels 61 stop each time, the specifications of the two pipe-piercing molds 62 passed through the plastic corrugated pipe conveying path are consistent; while the spacing adjustment mechanism 53 synchronously adjusts the distance between the two conveying components 51, the two adjusting wheels 61 rotate synchronously. After the distance adjustment of the two conveying components 51 is completed, on the plastic corrugated pipe conveying path, the specifications of the plastic corrugated pipe that can pass between the two conveying components 51 are consistent with the specifications that can pass through the pipe-piercing mold 62.

[0032] When in use, first, according to the specifications of the plastic corrugated pipe to be cut, the distance between the two conveying components 51 and the horizontal conveying surface is synchronously adjusted through the spacing adjustment mechanism 53, and the spacing between the two conveying components 51 is adjusted to the pipe diameter corresponding to the specifications of the plastic corrugated pipe to be cut. During the spacing adjustment process between the two conveying components 51, the two symmetrically arranged adjusting wheels 61 also rotate synchronously to adjust the specifications of the pipe-piercing molds 62 on the conveying path of the plastic corrugated pipe. Since the angle ratio between several pipe-piercing molds 62 with successively increasing specifications and the pipe-piercing mold 62 with the smallest specification on the surface of each adjusting wheel 61 is consistent with the specification ratio between several pipe-piercing molds 62 with successively increasing specifications and the pipe-piercing mold 62 with the smallest specification, the angle ratio between two adjacent pipe-piercing molds 62 and the ratio of the spacing adjustment interval between the two conveying components 51 are also correspondingly equal, so that after each adjustment is completed, the two conveying components 51 After the distance adjustment is completed, on the plastic corrugated tube conveying path, the specifications of the plastic corrugated tube that can pass through the two conveying assemblies 51 are consistent with the specifications that can pass through the tube-piercing mold 62, thereby making it possible to synchronously adjust the specifications of the tube-piercing mold 62 on the plastic corrugated tube conveying path during the distance adjustment of the two conveying assemblies 51, so that the specifications of the plastic corrugated tube passed by the distance of the two conveying assemblies 51 after each adjustment are consistent with the specifications of the plastic corrugated tube that can pass through the tube-piercing mold 62 on the plastic corrugated tube conveying path, so that when the specifications of the plastic corrugated tube to be cut are replaced, only the spacing adjustment mechanism 53 can be adjusted to adjust the spacing adjustment mechanism 53 and the specifications of the tube-piercing mold 62 at the same time, thereby reducing the number of units that need to be adjusted and controlled, avoiding the problem of misoperation caused by the increase in the number of adjustment units, and effectively ensuring the accuracy of the specifications of the plastic corrugated tubes that can be cut by this high-speed plastic corrugated tube cutting machine;

[0033] After adjusting the specifications of the plastic corrugated tubes that this high-speed plastic corrugated tube cutting machine can currently cut, this high-speed plastic corrugated tube cutting machine performs cutting operations on plastic corrugated tubes of corresponding specifications. The plastic corrugated tube enters between the two conveying components 51 of the power input mechanism 5 under the guidance of the guide mechanism 3. The synchronous drive mechanism 52 simultaneously drives the two conveying components 51 to rotate synchronously, and conveys the plastic corrugated tube into the two pipe threading molds 62. When the length of the plastic corrugated tube reaches the set value after passing through the cutting unit 21, the cutting mechanism 2 cuts the plastic corrugated tube, and then the cutting mechanism 2 cuts the plastic corrugated tube according to actual production needs. During the subsequent continued movement of the plastic corrugated tube, the cut plastic corrugated tube is pushed into the collecting mechanism 4 for collection, completing the cutting of the plastic corrugated tube.

[0034] Further, see Figure 4-Figure 7The conveying assembly 51 includes a driving belt 511, a driving pulley 512 and several supporting pulleys 513; the driving belt 511 is tensioned and arranged on the outside of the driving pulley 512 and the several supporting pulleys 513, and the driving pulley 512 is used to drive the driving belt 511 to rotate under the restriction of the driving pulley 512 and the several supporting pulleys 513.

[0035] The driving belt 511 includes several link units 5111 connected in series. A driving unit 5112 is provided on the outside of each link unit 5111. The side of the driving unit 5112 away from the link unit 5111 is an arc surface, and the surface of the arc surface is provided with several corrugated grooves.

[0036] When in use, the driving pulley 512 can drive the driving belt 511 to rotate under the restriction of the driving pulley 512 and several supporting pulleys 513, thereby driving the driving units 5112 arranged on the outside of the link unit 5111 to rotate, and since several corrugated grooves are opened on the curved surface of each driving unit 5112, they can clamp the corrugations of the plastic corrugated tube to be cut, so that during the movement of each driving unit 5112, the plastic corrugated tube can move along.

[0037] Further, see Figure 4-Figure 7 The synchronous drive mechanism 52 includes a driving gear 521, a driven gear 522 and a tensioning gear 523. The driving gear 521 and the driven gear 522 are connected to each other through a toothed belt 524, and the toothed belt 524 is also meshed with the tensioning gear 523; a reversing gear 525 is also provided on one side of the driven gear 522, and the reversing gear 525 is meshed with the driven gear 522; the driving gear 521 and the reversing gear 525 are respectively coaxially fixed to a driving pulley 512 of a conveying component 51. During the distance adjustment process between the driving gear 521 and the driven gear 522, the tensioning gear 523 moves to keep the toothed belt 524 in a tensioned state.

[0038] The synchronous drive mechanism 52 also includes a rotation drive motor 526, which is power-connected to the driving gear 521. The rotation drive motor 526 drives the driving gear 521 and the driven gear 522 to rotate synchronously. After the reversing gear 525 reverses, the two drive belts 511 of the two conveying assemblies 51 can rotate at equal speeds and in opposite directions, driving the plastic bellows between the two drive belts 511 to move.

[0039] The spacing adjustment mechanism 53 includes two positioning plates 531, and the driving pulley 512 and several supporting pulleys 513 of a conveying component 51 are all fixed on one side of a positioning plate 531; the spacing adjustment mechanism 53 also includes a spacing adjustment screw 532, and the two ends of the spacing adjustment screw 532 are respectively provided with threads with equal pitches and opposite directions, and the two ends of the spacing adjustment screw 532 are respectively engaged with the threads between the two positioning plates 531; the spacing adjustment mechanism 53 also includes a spacing drive motor 533, and the spacing drive motor 533 is power-connected to the spacing adjustment screw 532. The spacing drive motor 533 drives the spacing adjustment screw 532 to rotate, thereby driving the two positioning plates 531 to move equidistantly in opposite directions, thereby adjusting the spacing between the two conveying components 51.

[0040] When the distance between the two conveying assemblies 51 needs to be adjusted, the distance driving motor 533 drives the distance adjusting screw 532 to rotate. Since the two ends of the distance adjusting screw 532 are respectively provided with threads with equal pitch and opposite directions, the two ends of the distance adjusting screw 532 are respectively engaged with the threads between the two positioning plates 531, so that the two positioning plates 531 move equidistantly in opposite directions, adjusting the driving pulley 512 and the plurality of supporting pulleys 513 respectively fixed on one side of the positioning plate 531 to move, thereby driving the distance between the two conveying assemblies 51 to be adjusted; and in the process of adjusting the distance between the above-mentioned two conveying assemblies 51, the tensioning gear 523 moves to keep the toothed belt 524 in a tensioned state, so that the driving gear 521 and the driven gear 522 can still be connected by power through the toothed belt 524, thereby driving the two conveying assemblies 51;

[0041] When the two conveying assemblies 51 drive the plastic bellows, the rotating drive motor 526 drives the driving gear 521 to rotate. Under the action of the tensioning gear 523, the toothed belt 524 is kept in a tensioned state, and the driven gear 522 rotates synchronously with the driving gear 521. Since the reversing gear 525 is engaged with the driven gear 522, the driving gear 521 and the reversing gear 525 are respectively coaxially fixed to the driving pulley 512 of one conveying assembly 51, thereby driving the two driving pulleys 512 of the two conveying assemblies 51 to rotate at equal speeds and in opposite directions, driving the plastic bellows between the two driving belts 511 to move.

[0042] Further, see Figure 4-Figure 7The positioning and correction mechanism 6 also includes a transmission unit 63 and a rotation drive unit 64. The transmission unit 63 includes a driving worm 631 and a transmission worm gear 632. The driving worm 631 and the transmission worm gear 632 are driven by a worm gear. The driving worm 631 is coaxially fixed with the spacing adjustment screw 532. The rotation drive unit 64 includes two adjusting gears 641. The two adjusting gears 641 are coaxially fixed with the two adjusting wheels 61 respectively, and the two adjusting gears 641 are engaged with each other. The transmission worm gear 632 is power-connected to any one of the adjusting gears 641.

[0043] A lifting mechanism 65 is provided on the front of the adjusting wheel 61, and the lifting mechanism 65 includes a lifting track 651, and the lifting track 651 includes a hidden area and a lifting area; when the adjusting wheel 61 rotates, each pipe-piercing mold 62 moves under the restriction of the lifting track 651. When any pipe-piercing mold 62 moves to the lifting area of the lifting track 651, the pipe-piercing mold 62 located in the lifting area moves to the plastic corrugated pipe conveying path.

[0044] Therefore, during use, since the driving worm 631 and the spacing adjustment screw 532 are coaxially fixed, in the process of adjusting the spacing between the two conveying assemblies 51 by the spacing adjustment screw 532, the transmission turbine 632 is driven to rotate at the same time, and then the adjusting gear 641 connected to the transmission turbine 632 is driven to rotate, so that the two adjusting wheels 61 can be driven to rotate at the same speed and in opposite directions through the gear meshing between the two adjusting gears 641, so that the pipe-piercing molds 62 on each adjusting wheel 61 are all moved under the restriction of the lifting rail 651 until any one of the pipe-piercing molds 62 moves to the lifting area of the lifting rail 651, and the pipe-piercing mold 62 located in the lifting area moves to the plastic corrugated pipe conveying path. Therefore, after the spacing between the two conveying assemblies 51 is adjusted, the corresponding two pipe-piercing molds 62 of the same specification are also moved to the lifting area, so that only the two pipe-piercing molds 62 of the corresponding specifications are located in the lifting area, and only the pipe-piercing molds 62 in the lifting area can be in the plastic corrugated pipe conveying path, thereby ensuring the later cutting of the plastic corrugated pipe.

[0045] Further, see Figure 2-Figure 3 The cutting mechanism 2 includes a cutting unit 21, which is arranged between the two adjusting wheels 61. When the length of the plastic corrugated tube passing through the cutting unit 21 reaches a set value, the plastic corrugated tube is cut off; the cutting mechanism 2 also includes a cutting unit 22, which is arranged between the positioning and correction mechanism 6 and the collecting mechanism 4. The cutting unit 22 can pierce and extend into the interior of the passing plastic corrugated tube to cut the plastic corrugated tube open.

[0046] The cutting unit 21 includes a cutting blade 211 and a lifting guide rail 212. The cutting blade 211 can move up and down quickly along the path restricted by the lifting guide rail 212 to cut the plastic corrugated tube; the cutting unit 22 includes a cutting knife 221 and an electric telescopic rod. The movable end of the electric telescopic rod is fixed to the cutting knife 221. The electric telescopic rod is used to drive the cutting knife 221. The raised cutting knife 221 can contact the plastic corrugated tube to cut the plastic corrugated tube.

[0047] Therefore, during use, the cutting blade 211 can reciprocate regularly along the path restricted by the lifting guide rail 212, and cut the plastic corrugated tube regularly according to the transmission speed of the plastic corrugated tube to obtain a plastic corrugated tube of appropriate length, and then it is raised under control by the electric telescopic rod. According to actual processing requirements, the raised cutting knife 221 contacts the plastic corrugated tube to cut the plastic corrugated tube, thereby completing the cutting processing operation of the plastic corrugated tube.

[0048] Working principle: When in use, first, according to the specifications of the plastic corrugated pipes to be cut, the distance between the two conveying assemblies 51 and the horizontal conveying surface is synchronously adjusted by the spacing adjustment mechanism 53, so that the spacing between the two conveying assemblies 51 is adjusted to the pipe diameter corresponding to the specifications of the plastic corrugated pipes to be cut. At this time, the spacing drive motor 533 drives the spacing adjustment screw 532 to rotate. Since the two ends of the spacing adjustment screw 532 are respectively provided with threads with equal pitches and opposite directions, the two ends of the spacing adjustment screw 532 are respectively threadedly engaged with the two positioning plates 531, so that the two positioning plates 531 move equidistantly in opposite directions, and the driving pulley 512 and the plurality of supporting pulleys 513 respectively fixed on one side of the positioning plate 531 are adjusted to move, thereby driving the spacing between the two conveying assemblies 51 to be adjusted; and in the process of adjusting the spacing between the above-mentioned two conveying assemblies 51, the tensioning gear 523 moves to keep the toothed belt 524 in a tensioned state, so that the driving gear 521 and the driven gear 522 can still be connected by power through the toothed belt 524, thereby driving the two conveying assemblies 51;

[0049] During the process of adjusting the spacing between the two conveying assemblies 51, since the driving worm 631 and the spacing adjustment screw 532 are coaxially fixed, in the process of adjusting the spacing between the two conveying assemblies 51 by the spacing adjustment screw 532, the transmission turbine 632 is driven to rotate at the same time, and then the adjusting gear 641 connected to the transmission turbine 632 is driven to rotate, so that the two adjusting gears 641 can be engaged with each other to drive the two adjusting wheels 61 to rotate at the same speed and in opposite directions, so that the pipe-piercing molds 62 on each adjusting wheel 61 are all moved under the restriction of the lifting rail 651 until any one of the pipe-piercing molds 62 moves to the lifting area of the lifting rail 651, and the pipe-piercing mold 62 located in the lifting area moves to the plastic corrugated pipe conveying path. After the spacing between the two conveying assemblies 51 is adjusted, the corresponding two pipe-piercing molds 62 of the same specification are also moved to the lifting area, so that only the two pipe-piercing molds 62 of the corresponding specifications are located in the lifting area, and only the pipe-piercing molds 62 in the lifting area can be in the plastic corrugated pipe conveying path, ensuring the later cutting of the plastic corrugated pipe.

[0050] Among them, since on the surface of each adjusting wheel 61, the angle ratio between the plurality of pipe-piercing molds 62 with successively increasing specifications and the pipe-piercing mold 62 with the smallest specification is consistent with the specification ratio between the plurality of pipe-piercing molds 62 with successively increasing specifications and the pipe-piercing mold 62 with the smallest specification, the angle ratio between two adjacent pipe-piercing molds 62 and the ratio of the spacing adjustment interval between the two conveying components 51 are also correspondingly equal, so that after each adjustment is completed, after the distance adjustment of the two conveying components 51 is completed, on the conveying path of the plastic corrugated pipe, the specifications of the plastic corrugated pipe that can pass between the two conveying components 51 are consistent with the specifications that can pass through the pipe-piercing mold 62, thereby making it possible to adjust the distance between the two conveying components 51 During the distance adjustment process, the specifications of the tube-piercing mold 62 on the plastic corrugated tube conveying path are adjusted synchronously, so that the specifications of the plastic corrugated tubes passed by the distance between the two conveying components 51 after each adjustment are consistent with the specifications of the plastic corrugated tubes that can pass through the tube-piercing mold 62 on the plastic corrugated tube conveying path. Therefore, when the specifications of the plastic corrugated tubes to be cut are changed, only the spacing adjustment mechanism 53 can be adjusted to adjust the spacing of the spacing adjustment mechanism 53 and the specifications of the tube-piercing mold 62 at the same time, thereby reducing the number of units that need to be adjusted and controlled, avoiding the problem of misoperation caused by the increase in the number of adjustment units, and effectively ensuring the accuracy of the specifications of the plastic corrugated tubes that can be cut by this high-speed plastic corrugated tube cutting machine.

[0051] After adjusting the specifications of the plastic corrugated tubes that this high-speed plastic corrugated tube cutting machine can currently cut, this high-speed plastic corrugated tube cutting machine performs a cutting operation on the plastic corrugated tubes of corresponding specifications. The plastic corrugated tube enters between the two conveying components 51 of the power input mechanism 5 under the guidance of the guide mechanism 3, and the rotation drive motor 526 drives the active gear 521 to rotate. The toothed belt 524 keeps the toothed belt 524 in a tensioned state under the action of the tensioning gear 523, and the driven gear 522 rotates synchronously with the active gear 521. Due to the meshing between the reversing gear 525 and the driven gear 522, the active gear 521 and the reversing gear 525 are respectively coaxially fixed with the driving pulley 512 of one conveying component 51, thereby driving the two driving pulleys 512 of the two conveying components 51 to rotate at equal speeds and in opposite directions, thereby driving the driving units 5112 arranged on the outside of the link unit 5111 to rotate, and since the arc surfaces of each driving unit 5112 are all open The several corrugated grooves provided can clamp the corrugations of the plastic corrugated tube to be cut, so that the plastic corrugated tube can move along with the movement of each driving unit 5112; the two conveying components 51 rotate synchronously to convey the plastic corrugated tube into the two tube-threading molds 62. When the length of the plastic corrugated tube after passing through the cutting unit 21 reaches the set value, the cutting mechanism 2 cuts the plastic corrugated tube, and then the cutting mechanism 2 can reciprocate regularly along the path restricted by the lifting guide rail 212 according to actual production needs, and cut the plastic corrugated tube regularly according to the transmission speed of the plastic corrugated tube to obtain a plastic corrugated tube of appropriate length, and then it is raised in a controlled manner by the electric telescopic rod. According to actual processing requirements, the raised cutting knife 221 contacts the plastic corrugated tube to cut the plastic corrugated tube, completing the cutting processing operation of the plastic corrugated tube, and in the subsequent continued movement of the plastic corrugated tube, the cut plastic corrugated tube is pushed to fall into the collecting mechanism 4 for collection, completing the cutting of the plastic corrugated tube.

[0052] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
