Description

Technical Field

[0001] The present invention relates to the technical field of paper tube slitting, and in particular to a positioning device for a paper tube slitting machine and a use method thereof. Background Art

[0002] The paper tube slitting machine is a device used to achieve batch cutting of paper tubes. It has a moderate platform height, is easy to operate, runs noiselessly, and consumes little power for the transmission load. The machine uses laser or circular knife cutting and is widely used in many industries, such as textile, papermaking, packaging, printing, etc. It is especially suitable for various types of short lengths and large quantities of paper tubes. It also has the advantages of small size, simple and convenient operation, low price, multiple cutting methods and low power consumption.

[0003] Paper tube slitting is usually done with a paper tube slitting machine.

[0004] The existing patent (publication number: CN219616956U) discloses a paper tube positioning device for a slitting machine, which is installed on the upper part of the slitting machine. The paper tube positioning device for a slitting machine includes a support beam, a mounting seat and a plurality of laser emitters. The support beam is installed on the slitting machine in the use state. The mounting seat is installed on the support beam and forms a horizontal moving pair with the support beam. A fixing piece is provided on the mounting seat, which is used to fix the mounting seat on the support beam after the mounting seat moves to a predetermined position. The laser emitter is installed on the mounting seat, and the laser emitted by the laser emitter is directed to the paper tube to be cut on the slitting machine to determine the position of the cutter on the slitting machine. In the above-mentioned device, the position of the laser emitter on the support beam is adjustable, but the adjustment accuracy is limited. When mass-producing paper tubes, it will cause a waste of resources, and the laser emitter only plays a positioning effect, and the cutting device needs to be additionally aligned, which is inconvenient to use.

[0014] Preferably, the number of the fixing pins is ten, and the ten fixing pins are equidistantly distributed on the top surface of the fixed ruler, the number of the positioning connecting grooves is ten, and the ten positioning connecting grooves are equidistantly distributed on the top surface of the sliding ruler, the movable column is slidably connected to the positioning base, the positioning ball head is abutted against the positioning connecting groove, and the limit buckle is slidably connected to the outer surface of the fixing pin.

[0015] A method for using a positioning device for a paper tube slitting machine comprises the following steps:

[0016] S1. Adjust the position of the positioning base according to the required length of the paper tube to be cut. First, rotate and lift the connecting pin at the corresponding size. At this time, the corresponding positioning connecting groove at the bottom of the sliding ruler will be vacant. Push the positioning base. The positioning ball head will slide directly from the surface when passing the connecting pin that has not been lifted until it touches the vacant positioning connecting groove. At this time, the positioning ball head is lifted up by the lifting spring and stuck in the positioning connecting groove. The position of the positioning base is fixed. By setting ten equidistantly distributed positioning connecting grooves, the adjustment of ten positions of the positioning base is realized. The sliding ruler can slide on the fixed ruler. The fixed ruler is also provided with ten equidistantly distributed fixing pins, but the spacing between the fixing pins is smaller than the spacing between the fixing pins. In the initial state, only the rearmost fixing pin is aligned with the positioning connecting groove, and the rest are all misaligned. Pull out the limit buckles stuck on the fixing pins and the connecting pins, push the positioning base, and move the Xth connecting pin at the rear. Align with the Xth fixed pin at the rear, and clamp the limit buckle on the newly aligned connecting pin and fixing pin. At this time, the position of the sliding ruler is fixed. During the alignment process, the sliding ruler will move a distance. Every time the limit buckle passes through a group of connecting pins and fixing pins, the moving distance is the difference between the spacing of the positioning connecting groove and the spacing of the fixing pins. Since there are ten fixing pins and connecting pins that can be aligned, ten more fixable spacings can be added to each of the ten positions of the original positioning base, so that the positioning base can have more positioning intervals, and the spacing between each positioning is smaller, so as to achieve more precise positioning. When the paper tube is cut, the length of each paper tube is easier to control. After the cutting position is determined, the rear axle motor drives the connecting gear on the outer shaft of the paper tube to rotate through the output gear, so that the outer shaft of the paper tube and the paper tube sleeved on the surface rotate, and the laser cutting device installed on the cutting mounting seat is used for cutting;

[0017] S2, adjust the installation position of the push-pull connecting rod on the fan-shaped block. The closer the push-pull connecting rod is to the center of the fan-shaped block, the greater the swing angle of the fan-shaped block each time. Start the swing motor, and push and pull the fan-shaped block back and forth to make it swing by rotating the crank and the push-pull connecting rod. During the swinging of the fan-shaped block, it does not directly drive the top active rack to swing, but pushes the active rack through the delayed push-pull blocks on both sides. Since the delayed push-pull blocks can adjust their positions on the fan-shaped blocks, the interval and time of pushing the active rack each time can be controlled. The reciprocating swing of the active rack drives the driven gear to rotate, and finally drives the paper tube shaft to swing, so as to realize the control so that the paper tube shaft can be in two states: horizontal and inclined. The time and interval of the paper tube shaft in the inclined state are controlled by the delayed push-pull blocks to adapt to the sliding time of paper tubes with different cutting lengths.

[0018] S3, when the paper tube axis is in an inclined state, the support ring and the end stopper are retracted, and the surface of the entire paper tube axis is smooth, which is used to sleeve the paper tube, or slide the cut paper tube from the surface. When the paper tube axis is horizontal, the support ring is extended, and the end stopper is perpendicular to the paper tube axis. The uncut part of the paper tube is supported by the support ring, and the other end is blocked by the end stopper. When the paper tube axis switches from a horizontal state to an inclined state, the original moving path of the pulling rod on the pulling ring is an arc, but because the pulling rod is in the path limiting block, the pulling rod will move along the inner wall of the path limiting block, and the moving distance will be reduced, so the inner axis of the paper tube is pulled, and the inner axis of the paper tube will pull the support ring to retract it, and the end stopper to make it parallel to the inner axis of the paper tube, so that the paper tube sleeved on the surface is supported and fixed when the paper tube axis is horizontal, and no longer supported and fixed when tilted, so that the paper tube can slide out under the influence of gravity;

[0019] S4. The outer push rod and the inner push rod can be rotated to expand or retract, and the drive spring drives the expansion. During the expansion process, the sliding ring will be pushed to slide on the driven guide rod, and the push ring will be pushed to slide on the outer axis of the paper tube, pushing the uncut paper tube at the rear to the front for slitting. The driven guide rod and the fixed guide rod can be rotated to adapt to the horizontal and tilted state of the paper tube axis. When the sliding ring slides on the driven guide rod, it will pull the traction rope and rotate the reel. If the driven guide rod and the fixed guide rod are in a parallel and collinear state at this time, the reel will be reeled. The disk can rotate freely without affecting the movement of the sliding sleeve. When the driven guide rod rotates following the inclination of the paper tube axis, the push-pull arm pushes the sliding sleeve through the connecting arm and locks the locking block in the locking groove outside the winding disk. At this time, the winding disk cannot rotate. The sliding sleeve is constrained by the traction rope, and the push ring cannot push the paper tube. When the paper tube axis tilts to output the cut paper tube, the uncut paper tubes at the rear will not be pushed out completely, and when the paper tube axis returns to a horizontal state, the rear paper tube is pushed to the front for cutting.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] In the present invention, through the cooperation of the paper shaft swing mechanism and the paper tube shaft, a crank rocker structure is used to convert rotation into reciprocating swing, and the swing angle can be adjusted. During the swinging process, the push and pull of the inner shaft of the paper tube is controlled, and then the support ring and the end stopper are controlled. When the paper tube is horizontal, it is fixed for cutting, and when it is tilted, the paper tube is loosened for discharge, so that the paper tube can be quickly rotated and discharged during the cutting process, thereby improving the cutting speed and efficiency. In addition, the time when tilting is adjustable, and the interval time of discharging the paper supply tube is controlled, thereby increasing the flexibility of the machine and being able to adapt to paper tubes of different specifications and shapes.

[0022] In the present invention, through the cooperation of the pushing mechanism and the paper tube shaft, the pushing mechanism can be controlled according to the state of the paper tube shaft, so that no pushing is done when the paper tube shaft is tilted for discharging, and the cut paper tube can slide naturally. When the paper tube shaft is horizontal, the paper tube set at the rear can be pushed outward for cutting, which reduces manual operation, improves production efficiency and convenience of operation, and manual labor will not directly contact the cutting area, reducing the risk of operator injury.

[0023] In the present invention, by setting up the slitting and positioning mechanism, during use, a staggered alignment method is used to manually adjust a smaller distance, which is used to accurately adjust and position the size of the cut paper tube, so that the size of the cut paper tube can be adjusted very accurately. A cutting mounting seat is directly installed on the slitting and positioning mechanism to install the cutting device, so that the positioning and cutting positions are always kept synchronized, thereby ensuring the accuracy and consistency of the cutting, reducing material waste and improving production efficiency, thereby reducing unit costs.

DETAILED DESCRIPTION

[0041] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technical personnel in the field without making creative work are within the scope of protection of the present invention.

[0042] See also Figures 1 to 16The present invention provides a technical solution: a paper tube slitting machine positioning device and a use method, comprising an installation shell 1, one end of the installation shell 1 is fixedly connected to a support base 11, the inner surface of the installation shell 1 is fixedly connected to an inner mounting seat 2, the top surface of the installation shell 1 is fixedly connected to an axis motor 3, the output end of the axis motor 3 is fixedly connected to an output gear 31, the outer surface of the output gear 31 is meshed with a connecting gear 32, the outer surface of the inner mounting seat 2 is provided with a paper axis swing mechanism 4, the inner surface of the installation shell 1 is provided with a paper tube axis 5, the outer surface of the installation shell 1 is provided with a pushing mechanism 6, and the outer surface of the support base 11 is provided with a slitting positioning mechanism 7. The installation shell 1 is used to install and protect internal components, the inner mounting seat 2 is used to install various components on the paper axis swing mechanism 4 internally, and the support base 11 supports the slitting positioning mechanism 7. The axis motor 3 meshes with the connecting gear 32 outside the paper tube outer shaft 55 through the output gear 31, so that the axis motor 3 outside drives the paper tube outer shaft 55 to rotate.

[0043] The paper shaft swing mechanism 4 includes a swing motor 41, which is fixedly connected to the outer surface of the inner mounting seat 2, and the output end of the swing motor 41 is fixedly connected to a rotating crank 411, and the outer surface of the rotating crank 411 is rotatably connected to a push-pull connecting rod 412, and the other end of the push-pull connecting rod 412 is bolted to a fan-shaped block 42, and the outer surface of the fan-shaped block 42 is provided with a connecting rod connecting groove 421, and the top surface of the fan-shaped block 42 is fixedly connected to a sliding guide rail 43, and the outer surface of the sliding guide rail 43 is slidably connected to a delayed push-pull block 431, and the inner surface of the delayed push-pull block 431 is threadedly connected to a locking nut 4311, and the outer surface of the sliding guide rail 43 is slidably connected to an active rack 44, and the outer surface of the active rack 44 is meshed with a driven gear 45. Through the setting of the paper shaft swing mechanism 4, during use, the swing motor 41 drives the rotating crank 411 to rotate, and the rotating crank 411, the push-pull connecting rod 412 and the fan-shaped block 42 form a crank rocker structure. The structure converts rotation into reciprocating swing, and adjusts the distance between the push-pull connecting rod 412 and the center of the circle of the sector block 42 to adjust the angle during swinging. The closer the sector block 42 is, the larger the swing angle is. When the sector block 42 swings, it drives the two delayed push-pull blocks 431 on the surface to swing. The delayed push-pull block 431 will push the active rack 44 when it contacts it. In the initial state, the delayed push-pull block 431 on one side is in close contact with the active rack 44, while the delayed push-pull block 431 on the other side is separated. At this time, the sector block 42 swings first and uses the closely attached delayed push-pull block 431 to push the active rack 44. The active rack 44 is tilted with the paper tube shaft 5 through the driven gear 45. The sector block 42 swings in the opposite direction. The delayed push-pull block 431 separated at the beginning cannot contact the active rack 44. The sector block 42 continues to swing until the delayed push-pull block 431 contacts the active rack 44. At this time, the driven gear 45 is reset with the paper tube shaft 5. The time period during which the separated delayed push-pull block 431 and the active rack 44 wait for contact is the time for the paper tube shaft 5 to maintain the tilted state.

[0044] The fan-shaped block 42 is rotatably connected to the outer surface of the inner mounting seat 2, the connecting bolt of the push-pull connecting rod 412 passes through the connecting rod connecting groove 421, the number of delayed push-pull blocks 431 is two, the locking nut 4311 is against the outer surface of the sliding guide rail 43, the connecting bolt of the push-pull connecting rod 412 passes through the connecting rod connecting groove 421, and the position of the push-pull connecting rod 412 on the inner mounting seat 2 is locked by the bolt, while the push-pull connecting rod 412 can still rotate on the bolt without affecting the rotation, and the symmetrical delayed push-pull blocks 431 can adjust the trigger interval on both sides, thereby adjusting the maintenance time of the two states of the paper tube axis 5.

[0045] The paper tube shaft 5 includes an inner rotating bracket 51, which is fixedly connected to the inner surface of the mounting shell 1, and the inner surface of the inner rotating bracket 51 is rotatably connected to a swing base 52, and the outer surface of the swing base 52 is provided with a pulling groove 521, and the inner surface of the swing base 52 is slidably connected to a paper tube inner shaft 53, and the inner surface of the paper tube inner shaft 53 is fixedly connected to an inner connecting rod 531, and the other end of the inner connecting rod 531 is fixedly connected to an inner mounting plate 532, and the outer surface of the inner mounting plate 532 is hingedly connected to a support hinge rod 5 33, the outer surface of the supporting hinge rod 533 is hingedly connected with a supporting ring 534, one end of the paper tube inner shaft 53 is fixedly connected with a stopper pull rod 535, the outer surface of the stopper pull rod 535 is hingedly connected with an end stopper 536, the outer surface of the paper tube inner shaft 53 is rotatably connected with a pulling ring 54, one end of the pulling ring 54 is fixedly connected with a pulling rod 541, the inner surface of the mounting shell 1 is fixedly connected with a path limiting block 542, the outer surface of the paper tube inner shaft 53 is sleeved with a paper tube outer shaft 55, and the outer surface of the paper tube outer shaft 55 is provided with The stopper bracket 56 is fixedly connected to one end of the paper tube outer shaft 55 through the setting of the paper tube shaft 5. During use, the swing base 52 will also drive the pulling ring 54 to rotate around the inner rotating bracket 51 during the process of rotating around the inner rotating bracket 51. The original moving path of the pulling rod 541 should be an arc, but the pulling rod 541 is at the path limiting block 542. Although the rotation angle is the same, the position from the center of the inner rotating bracket 51 will be shortened, thereby pulling the paper tube inner shaft 53, and the pulling ring 54 does not affect the paper tube inner shaft 53. The rotation will only push and pull it, controlling the internal support ring 534 and the end stopper 536. The support ring 534 and the end stopper 536 will rotate along with the rotation of the paper tube inner shaft 53 and the paper tube outer shaft 55. A plurality of inner mounting plates 532 are installed inside the paper tube inner shaft 53, and the two sides are connected to the paper tube inner shaft 53 through inner connecting rods 531, thereby leaving space for the support hinge rod 533 to rotate.

When the first connecting pin 722 is When the connecting pin 722 is aligned with the first fixed pin 712, the sliding ruler 72 is in the initial position on the fixed ruler 71, and the second connecting pin 722 and the second fixed pin 712 are not aligned, but are staggered by the difference between the spacing of the connecting pins 722 and the spacing of the fixed pins 712, the difference being one, and each additional set of connecting pins 722 and fixed pins 712 is staggered by one more difference. Assuming that the sliding ruler 72 is pushed at this time to align the third connecting pin 722 with the third fixed pin 712, the sliding ruler 72 is in the initial position on the fixed ruler 71. 1, the moving distance is three, because the positioning base 73 has been stuck on the sliding ruler 72 through the positioning ball head 733, it will also move the same distance, so when the nth connecting pin 722 and the fixing pin 712 are aligned, the moving distance is n, so that in addition to the positioning base 73 itself being able to be stuck in ten positioning connecting grooves 721 to obtain ten positions, each position can be staggered to obtain ten positions, a total of one hundred positions can be positioned, and the size of the cut paper tube can be adjusted more accurately.

[0051] In this embodiment, Figure 1 , Figure 2 As shown, each component is installed by installing the housing 1, the inner mounting seat 2 and the supporting base 11;

[0052] In this embodiment, Figure 3 , Figure 4 As shown, the paper shaft swing mechanism 4 drives the paper tube shaft 5 to swing back and forth. The paper shaft swing mechanism 4 uses a crank rocker structure to convert the transport rotation into a reciprocating swing, and the interval and angle of the reciprocating swing are controlled by the push-pull connecting rod 412 and the delayed push-pull block 431. At this time, the delayed push-pull block 431 on one side is in close contact with the active rack 44, while the other side is separated. When rotating toward the separated side, the active rack 44 will be pushed immediately, and the active rack 44 will be pushed with a delay during the return trip.

[0053] In this embodiment, Figure 5 , Figure 6 , Figure 7 As shown, the pulling ring 54 is pushed and pulled by the path limiting block 542, and the distance between the pulling ring 54 and the center of the inner rotating bracket 51 will be changed, so as to push and pull the paper tube inner shaft 53, and then the supporting ring 534 and the end stopper 536 are controlled to support and rotate through the paper tube inner shaft 53. The supporting ring 534 and the end stopper 536 are located between the paper tube inner shaft 53 and the paper tube outer shaft 55, and will rotate with the rotation of the paper tube inner shaft 53 and the paper tube outer shaft 55;

[0054] In this embodiment, Figure 8 , Fig. 9 , Fig.10 As shown, the driven guide rod 63 and the fixed guide rod 62 can rotate to adapt to the horizontal and inclined state of the paper tube shaft 5, and when in the inclined state, the locking block 643 locks the locking groove 6213;

[0055] In this embodiment, Fig.11 As shown, the dimensions of the outer push rod 622 and the inner push rod 632 after being unfolded into a straight line are consistent with the dimensions of the fixed guide rod 62 and the driven guide rod 63 after being unfolded into a straight line. The unfolding is driven by the driving spring 6222. During the unfolding process, the sliding ring 631 is pushed to slide on the driven guide rod 63, and the push ring 65 is pushed to slide on the paper tube outer shaft 55.

[0056] In this embodiment, Fig.12 As shown, when the driven guide rod 63 and the fixed guide rod 62 are in a horizontal state, the locking block 643 and the locking groove 6213 are not in contact;

[0058] In this embodiment, Fig.16 As shown, each additional set of connecting pins 722 and fixing pins 712 is offset by one more difference. By adjusting the aligned connecting pins 722 and fixing pins 712, assuming that the sliding ruler 72 is pushed at this time to align the third connecting pin 722 and the third fixing pin 712, the sliding ruler 72 is offset from the fixed ruler 71, and the distance moved by the sliding ruler 72 on the fixed ruler 71 is three, the positioning base 73 also moves accordingly, and small spacing adjustment is achieved.

[0059] A method for using a positioning device for a paper tube slitting machine comprises the following steps:

[0060] S1. According to the required length of the paper tube to be cut, adjust the position of the positioning base 73. First, rotate and lift the connecting pin 722 at the corresponding size. At this time, the corresponding positioning connecting groove 721 at the bottom of the sliding ruler 72 will be vacant. Push the positioning base 73. The positioning ball head 733 will directly slide from the surface when passing the unlifted connecting pin 722 until it contacts the vacated positioning connecting groove 721. At this time, the positioning ball head 733 is lifted up by the lifting spring 731 and stuck in the positioning connecting groove 721. The position of the positioning base 73 is fixed By setting ten equidistantly distributed positioning connecting grooves 721, the positioning base 73 can be adjusted to ten positions. The sliding ruler 72 can slide on the fixed ruler 71. The fixed ruler 71 is also provided with ten equidistantly distributed fixing pins 712, but the spacing of the fixing pins 712 is smaller than the spacing of the positioning connecting grooves 721. In the initial state, only the rearmost fixing pin 712 is aligned with the positioning connecting groove 721, and the rest are all misaligned. The limit buckle 74 stuck on the fixing pin 712 and the connecting pin 722 is pulled out, and the positioning base 73 is pushed to move the rear fixing pin 712 to the rear. The Xth connecting pin 722 on the front is aligned with the Xth fixing pin 712 on the rear, and the limiting buckle 74 is clamped on the newly aligned connecting pin 722 and fixing pin 712. At this time, the position of the sliding ruler 72 is fixed. During the alignment process, the sliding ruler 72 will move a certain distance. Every time the limiting buckle 74 passes through a group of connecting pins 722 and fixing pins 712, the moving distance is increased by the difference between the spacing of the positioning connecting groove 721 and the spacing of the fixing pins 712. Since there are ten fixing pins 712 and connecting pins 722 that can be aligned, the original The positioning base 73 has ten positions, and each position has ten more fixed intervals, so that the positioning base 73 can have more positioning intervals, and the interval between each positioning is smaller, so that more precise positioning can be achieved. When the paper tube is cut, the length of each paper tube is easier to control. After the cutting position is determined, the rear axle motor 3 drives the connecting gear 32 on the paper tube outer shaft 55 to rotate through the output gear 31, so that the paper tube outer shaft 55 and the paper tube sleeved on the surface rotate, and the laser cutting device installed on the cutting mounting seat 75 is used for cutting;

[0061] S2, adjust the installation position of the push-pull connecting rod 412 on the sector block 42. The closer the push-pull connecting rod 412 is to the center of the sector block 42, the greater the swing angle of the sector block 42 each time. Start the swing motor 41, and push and pull the sector block 42 back and forth to make it swing by rotating the crank 411 and the push-pull connecting rod 412. During the swinging of the sector block 42, it does not directly drive the top active rack 44 to swing, but pushes the active rack 44 through the delayed push-pull blocks 431 on both sides. Since the delayed push-pull blocks 431 can be adjusted to their positions on the sector block 42, the interval and time of each push of the active rack 44 can be controlled. The reciprocating swing of the active rack 44 drives the driven gear 45 to rotate, and finally drives the paper tube shaft 5 to swing, so as to realize control so that the paper tube shaft 5 can be in two states, horizontal and inclined. The time and interval of the paper tube shaft 5 in the inclined state are controlled by the delayed push-pull blocks 431 to adapt to the sliding time of paper tubes with different cutting lengths.

[0062] S3, when the paper tube shaft 5 is in an inclined state, the support ring 534 and the end stopper 536 are retracted, and the surface of the entire paper tube shaft 5 is smooth, which is used to sleeve the paper tube, or slide the cut paper tube from the surface. When the paper tube shaft 5 is horizontal, the support ring 534 is extended, and the end stopper 536 is perpendicular to the paper tube shaft 5. The uncut part of the paper tube is supported by the support ring 534, and the other end is blocked by the end stopper 536. When the paper tube shaft 5 is switched from the horizontal state to the inclined state, the pull rod 54 on the sleeve ring 54 is pulled The original moving path is an arc, but because the pulling rod 541 is located in the path limiting block 542, the pulling rod 541 will move along the inner wall of the path limiting block 542, and the moving distance will be reduced, so the paper tube inner shaft 53 will be pulled, and the paper tube inner shaft 53 will pull the support ring 534 to retract it, and the end stopper 536 to make it parallel to the paper tube inner shaft 53, so that the paper tube sleeved on the surface is supported and fixed when the paper tube shaft 5 is horizontal, and the paper tube is no longer supported and fixed when it is tilted, so that the paper tube can slide away under the influence of gravity;

[0063] S4, the outer push rod 622 and the inner push rod 632 can be rotated to expand or retract, and are driven to expand by the driving spring 6222. During the expansion process, the sliding ring 631 will be pushed to slide on the driven guide rod 63, and the push ring 65 will be pushed on the outer shaft 55 of the paper tube to push the uncut paper tube at the rear to the front for slitting. The driven guide rod 63 and the fixed guide rod 62 can be rotated to adapt to the horizontal and inclined state of the paper tube shaft 5. When the sliding ring 631 slides on the driven guide rod 63, the traction rope 6212 will be pulled and the winding disk 6211 will be rotated. If the driven guide rod 63 and the fixed guide rod 62 are in a parallel and collinear state at this time, the winding disk 6 211 can rotate freely without affecting the movement of the sliding sleeve 631. When the driven guide rod 63 rotates following the inclination of the paper tube shaft 5, the push-pull arm 64 pushes the sliding sleeve 642 through the connecting arm 641, and the locking block 643 is stuck in the locking groove 6213 outside the winding disk 6211. At this time, the winding disk 6211 cannot rotate, and the sliding sleeve 631 is constrained by the traction rope 6212, so the push ring 65 cannot push the paper tube, so that when the paper tube shaft 5 tilts to output the cut paper tube, the uncut paper tubes at the rear will not be pushed out completely, and when the paper tube shaft 5 returns to a horizontal state, the rear paper tube is pushed to the front for cutting.

10. A method for using a positioning device for a paper tube slitting machine, using the positioning device for a paper tube slitting machine as claimed in any one of claims 1 to 9, characterized in that: The steps include: S1. According to the required length of the paper tube to be cut, adjust the position of the positioning base (73). First, rotate and lift the connecting pin (722) at the corresponding size. At this time, the corresponding positioning connecting groove (721) at the bottom of the sliding ruler (72) will be vacant. Push the positioning base (73). The positioning ball head (733) will directly slide over the surface when passing the unlifted connecting pin (722) until it contacts the vacant positioning connecting groove (721). At this time, the positioning ball head (733) is lifted by the lifting spring (731) and inserted into the positioning connecting groove (721). The position of the positioning base (73) is fixed. By setting ten equally spaced positioning connection grooves (721), the positioning base (73) can be adjusted to ten positions. The sliding ruler (72) can slide on the fixed ruler (71). The fixed ruler (71) is also provided with ten equally spaced fixed pins (712), but the spacing of the fixed pins (712) is smaller than the spacing of the positioning connection grooves (721). In the initial state, only the rearmost fixed pin (712) is aligned with the positioning connection groove (721), and the rest are all misaligned. The limit buckle (74) stuck on the fixed pin (712) and the connection pin (722) is pulled out, and the positioning base (73) is pushed. ), align the rear X-th connecting pin (722) with the rear X-th fixing pin (712), and clamp the limit buckle (74) on the newly aligned connecting pin (722) and fixing pin (712). At this time, the position of the sliding ruler (72) is fixed. During the alignment process, the sliding ruler (72) will move a distance. Each time the limit buckle (74) passes through a group of connecting pins (722) and fixing pins (712), the moving distance is increased by the difference between the spacing of the positioning connecting groove (721) and the spacing of the fixing pin (712). Since there are ten fixing pins (712) and connecting pins (722), After the paper tube is aligned, ten additional fixed intervals can be provided at each of the ten positions of the original positioning base (73), so that the positioning base (73) can have more positioning intervals, and the interval between each positioning interval is smaller, so that more precise positioning can be achieved. When the paper tube is cut, the length of each paper tube section is easier to control. After the cutting position is determined, the shaft motor (3) drives the connecting gear (32) on the paper tube outer shaft (55) to rotate through the output gear (31), so that the paper tube outer shaft (55) and the paper tube sleeved on the surface rotate, and the laser cutting device installed on the cutting mounting seat (75) performs cutting; S2, adjusting the installation position of the push-pull connecting rod (412) on the sector block (42), the closer the push-pull connecting rod (412) is to the center of the sector block (42), the greater the swing angle of the sector block (42) each time, starting the swing motor (41), and pushing and pulling the sector block (42) back and forth to make it swing by rotating the crank (411) and the push-pull connecting rod (412), and during the swinging process of the sector block (42), the top active rack (44) is not directly driven to swing, but the active rack is driven by the delayed push-pull blocks (431) on both sides. (44) is pushed, and since the delayed push-pull block (431) can be adjusted in position on the fan-shaped block (42), the interval and time of each push of the active rack (44) can be controlled, and the reciprocating swing of the active rack (44) drives the driven gear (45) to rotate, and finally drives the paper tube shaft (5) to swing, so that the paper tube shaft (5) can be controlled to be in two states of horizontal and inclined, and the time and interval of the paper tube shaft (5) in the inclined state are controlled by the delayed push-pull block (431) to adapt to the sliding time of paper tubes with different cutting lengths; S3, when the paper tube shaft (5) is in an inclined state, the support ring (534) and the end stopper (536) are retracted, and the surface of the entire paper tube shaft (5) is smooth, which is used to sleeve the paper tube, or slide the cut paper tube from the surface. When the paper tube shaft (5) is horizontal, the support ring (534) is extended, and the end stopper (536) is perpendicular to the paper tube shaft (5). The inside of the uncut part of the paper tube is supported by the support ring (534), and the other end is blocked by the end stopper (536). When the paper tube shaft (5) is switched from the horizontal state to the inclined state, the pull rod (536) on the sleeve ring (54) is pulled. The original moving path of the paper tube (541) is an arc, but because the pulling rod (541) is located in the path limiting block (542), the pulling rod (541) will move along the inner wall of the path limiting block (542), and the moving distance will be reduced, so the paper tube inner shaft (53) will be pulled, and the paper tube inner shaft (53) will pull the support ring (534) to retract it, and the end stopper (536) will make it parallel to the paper tube inner shaft (53), so that when the paper tube shaft (5) is horizontal, the paper tube sleeved on the surface is supported and fixed, and when it is tilted, it is no longer supported and fixed, so that the paper tube can slide away under the influence of gravity; S4, the outer push rod (622) and the inner push rod (632) can be rotated to unfold or retract, and are driven to unfold by the driving spring (6222). During the unfolding process, the sliding ring (631) is pushed to slide on the driven guide rod (63), and the push ring (65) is pushed to slide on the outer shaft (55) of the paper tube, so that the uncut paper tube at the rear is pushed to the front for cutting. The driven guide rod (63) and the fixed guide rod (62) can be rotated to adapt to the horizontal and inclined state of the paper tube shaft (5). When the sliding ring (631) slides on the driven guide rod (63), the traction rope (6212) is pulled and the winding disk (6211) is rotated. If the driven guide rod (63) and the fixed guide rod (62) are in a parallel and collinear state at this time, the winding disk (6211) is rotated. The sliding sleeve (6211) can rotate freely without affecting the movement of the sliding sleeve (631), and when the driven guide rod (63) rotates following the inclination of the paper tube shaft (5), the push-pull arm (64) pushes the sliding sleeve (642) through the connecting arm (641), and the locking block (643) is stuck in the locking groove (6213) outside the winding disk (6211). At this time, the winding disk (6211) cannot rotate, and the sliding sleeve (631) is constrained by the traction rope (6212), so that the push ring (65) cannot push the paper tube, so that when the paper tube shaft (5) tilts to output the cut paper tube, the uncut paper tube at the rear will not be pushed out completely, and when the paper tube shaft (5) returns to a horizontal state, the rear paper tube is pushed to the front for cutting.
