Description

Technical Field

[0001] This invention relates to the field of cable processing technology, and in particular to a self-sensing device for the breakage of wrapped tape and its high-speed shutdown protection device. Background Technology

[0002] Wrapping tape is commonly used in the continuous winding process of cables, pipes, composite materials, and insulation materials. The process requires mounting the tape roll on an unwinding or support structure, and then driving the tape roll to rotate through a transmission mechanism, so that the tape enters the subsequent winding station according to a predetermined path. Since wrapping is a continuous conveying operation, the tape needs to maintain a certain tension during operation. Only when the tape tension is stable can it smoothly enter the winding area after passing the guide part and be wound on the corresponding component according to the set position. If the tape breaks, loosens, or the tension suddenly decreases during the conveying process, the original conveying path of the tape will be disrupted, and the unwinding side may continue to rotate under inertia or transmission, resulting in problems such as tape accumulation, misalignment, uneven winding, or the need for equipment shutdown for maintenance.

[0003] In existing wrapping equipment, to reduce the impact of continued operation after tape breakage, photoelectric detection devices, tension detection devices, limit switches, or alarm devices are usually installed on the equipment. The tape breakage status is determined by detecting the presence of tape, whether the tension is normal, or whether the position of the swing arm has changed. When the detection device identifies an abnormality, it sends a signal to the control system, which then controls the drive motor to stop working, or uses external actuators to stop the transmission mechanism. This type of method can make a certain judgment on the tape breakage and can also work with the electrical control system to realize alarm or shutdown, so it is quite common in ordinary wrapping equipment.

[0004] However, existing methods that rely on detection signals to control shutdown require processes such as detection, signal transmission, control judgment, and shutdown execution. During this process, the fixing components may continue to rotate, and the strip roll may continue to release strip. Especially when the strip has lost tension, if the unwinding side is not restricted in time, the loose strip is prone to stacking and tangling on the fixing roller, guide part, or winding area. At the same time, the structure that relies solely on electronic shutdown lacks direct mechanical linkage with the strip tension state. The loss of strip tension itself cannot be directly converted into a locking action, causing the protection action to rely more on subsequent control signals, making it difficult to timely restrict the rotation of the fixing components in the early stage of strip breakage. Summary of the Invention

[0005] This invention overcomes the shortcomings of the prior art and provides a self-sensing device for the breakage of wrapping strip and its high-speed shutdown protection device.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is: a self-sensing device for the breakage of wrapping tape and its high-speed shutdown protection device, comprising:

[0007] Base plate;

[0008] A fixing component, disposed on the base plate, is used to install and support the strip coil;

[0009] A transmission component is disposed on the base plate and is connected to the fixed component in a transmission manner;

[0010] A traction component is mounted on the base plate and located on the conveying path of the strip;

[0011] A shutdown protection component is disposed on one side of the fixing component and is used to restrict the rotation of the fixing component when the strip tension decreases;

[0012] An adjustment component is located on the side of the fixed component away from the transmission component;

[0013] The shutdown protection component is used to maintain the unlocked position when the strip is tensioned, and to switch to the locked position when the strip breaks or the tension decreases, so as to restrict the fixed component from continuing to rotate; the adjustment component is used to guide the strip and cooperate with the traction component to complete the strip conveying.

[0014] In a preferred embodiment of the present invention, the fixing component includes a frame and a drive shaft. The frame is disposed on the top of the base plate, and a through hole is provided in the middle of the frame. The drive shaft is rotatably connected to the through hole.

[0015] In a preferred embodiment of the present invention, a plurality of fixed rollers are provided on one side of the frame, and the plurality of fixed rollers are arranged at intervals along the circumference of the frame.

[0016] In a preferred embodiment of the present invention, the transmission assembly includes a support plate and a drive motor. The support plate is disposed on one side of the frame, and the drive motor is disposed on the bottom inner wall of the support plate. The output end of the drive motor passes through the support plate and extends to the outside of the support plate.

[0017] In a preferred embodiment of the present invention, the transmission assembly further includes a gear belt and a second transmission shaft. The second transmission shaft is rotatably disposed between the top inner wall of the support plate. One end of the second transmission shaft passes through the support plate and extends to the outside of the support plate. The gear belt is connected between the output end of the drive motor and the second transmission shaft.

[0018] In a preferred embodiment of the present invention, the transmission assembly further includes a worm and a gear, the worm being sleeved on the outer wall of the second transmission shaft, the gear being sleeved on the outer wall of the first transmission shaft, and the worm meshing with the gear.

[0019] In a preferred embodiment of the present invention, the shutdown protection component includes a housing and a ratchet. The housing is fixedly connected to the frame, and the ratchet is disposed inside the housing and sleeved on the outer wall of the drive shaft. The ratchet can rotate synchronously with the drive shaft.

[0020] In a preferred embodiment of the present invention, the housing is provided with a plurality of trapezoidal grooves, and the shutdown protection component further includes a telescopic rod, which is slidably disposed in the plurality of trapezoidal grooves. The end of the telescopic rod away from the ratchet is provided with a threading hole for the strip to pass through.

[0021] In a preferred embodiment of the present invention, the shutdown protection component further includes a locking pin and a return spring. The locking pin is respectively disposed at one end of the telescopic rod near the ratchet, and the return spring is respectively sleeved on the outer wall of the telescopic rod. The return spring is used to push the telescopic rod toward the ratchet so that the locking pin engages with the ratchet.

[0022] In a preferred embodiment of the present invention, the adjusting assembly includes a fixed disk, a plurality of uprights, a plurality of adjusting posts, and a winding head. The fixed disk is fixedly sleeved on the outer wall of the drive shaft and can rotate synchronously with it. The plurality of uprights are disposed on the outer wall of the fixed disk, and the uprights are provided with tape passage holes for the tape to pass through. The plurality of adjusting posts are disposed on one side of the fixed disk, and the winding head is disposed between the plurality of adjusting posts.

[0023] This invention addresses the shortcomings of the prior art and has the following beneficial effects:

[0024] (1) By using the tension state of the strip itself as the mechanical trigger condition of the shutdown protection component, the strip moves upward through the thread hole when it is under normal tension, the locking pin is separated from the ratchet, and the drive shaft can drive the fixed roller and the fixed disc to rotate normally. When the strip breaks or the tension decreases, the return spring directly pushes the telescopic rod to reset, so that the locking pin enters the ratchet and restricts the drive shaft from continuing to rotate. This structure does not detect before stopping, but directly switches the locking state from the loss of tension of the strip. Compared with the shutdown method that relies on electronic control detection and external actuators, it can constrain the unwinding end more quickly and reduce the accumulation and entanglement of loose strip caused by continuing to unwind after the strip breaks.

[0025] (2) The structural foundation of the drive shaft 1 simultaneously undertakes the unwinding of the fixed roller, the ratchet locking and the winding guidance of the fixed disc. The drive motor transmits power to the drive shaft 1 through the gear belt, the second drive shaft, the worm gear and the gear. The strip is output from the fixed roller and passes through the telescopic rod, the column, the adjusting column and the winding head in sequence. Since the unwinding transmission path, the tension self-sensing path and the winding guidance path are all arranged around the drive shaft 1, the shutdown protection action can directly act on the source of strip release. Compared with the equipment where the unwinding, detection and winding structures are arranged separately, the action chain of this scheme is more concentrated, which can make the strip breakage lock more direct and reliable while maintaining normal wrapping and conveying.

[0026] (3) By setting several trapezoidal grooves in the housing and setting the telescopic rods in the corresponding trapezoidal grooves, the locking pins and return springs form independent locking units with the telescopic rods; after the strip passes through the end of the telescopic rod, each tension state of the strip can control the engagement and disengagement state between a set of locking pins and ratchet, so that the shutdown protection component forms a multi-position self-sensing protection around the drive shaft; compared with the method of setting detection or limiting structures in only a single position, this scheme can cover multiple unwinding and guiding positions. When the strip breaks or loosens at any position, it can be locked by triggering the corresponding telescopic rod, thereby improving the device's adaptability to different wrapping paths and the operating state of multiple strips.

Those skilled in the art will understand the specific meaning of the above terms in this application based on the specific circumstances.

[0037] like Figures 1-4 As shown, a self-sensing device for wrapping tape breakage and its high-speed shutdown protection device includes:

[0038] Base plate 1;

[0039] Fixing component 2 is disposed on the base plate 1 and is used to install and support the strip roll;

[0040] The transmission component 3 is disposed on the base plate 1 and is connected to the fixing component 2 in a transmission manner;

[0041] The traction component 4 is mounted on the base plate 1 and located on the conveying path of the strip.

[0042] The shutdown protection component 5 is disposed on one side of the fixing component 2 and is used to restrict the rotation of the fixing component 2 when the strip tension decreases;

[0043] Adjustment component 6 is located on the side of the fixing component 2 away from the transmission component 3;

[0044] The shutdown protection component 5 is used to maintain the unlocked position when the strip is tensioned, and to switch to the locked position when the strip breaks or the tension decreases, so as to restrict the fixed component 2 from continuing to rotate; the adjustment component 6 is used to guide the strip and cooperate with the traction component 4 to complete the strip conveying.

[0045] The core concept of this invention is as follows: when the strip is being normally conveyed, the tension of the strip can pull the stop protection component 5 into an avoidance or unlocked state, so that the fixing component 2, the transmission component 3, and the adjusting component 6 can maintain continuous wrapping action; when the strip breaks, loosens, or the tension suddenly decreases, the stop protection component 5 can directly switch from the unlocked state to the locked state under the action of the return spring 55, so that the locking pin 54 and the ratchet 52 can engage, thereby restricting the transmission shaft 23 from continuing to rotate; thus, the strip tension loss action can be directly converted into mechanical constraint on the unwinding and guide base shaft system, reducing the lag caused by the traditional detection signal being judged by control before the stop is executed.

[0046] Example 1:

[0047] It should be noted that this embodiment is the basic implementation of the present invention. Its focus is on the fact that the base plate 1, the fixing component 2, the transmission component 3, the traction component 4 and the adjustment component 6 constitute the installation foundation and power foundation for the normal wrapping and conveying of the strip, and provide a rotating object that can be directly acted upon for the mechanical locking of the subsequent shutdown protection component 5.

[0048] Specifically, the base plate 1 is a plate-shaped mounting base used to support the fixing component 2, the transmission component 3, the traction component 4, and the adjustment component 6. The base plate 1 can be connected to the machine base of the wrapping equipment by bolts, positioning pins, welded connectors, or mounting slots to ensure that each component has a stable relative position during equipment operation. To improve assembly convenience, mounting holes, adjustment elongated holes, or positioning steps can be reserved on the base plate 1 to allow the frame 21, support plate 31, and traction component 4 to be installed and finely adjusted according to the strip conveying direction.

[0049] Furthermore, the fixing component 2 includes a frame 21 and a drive shaft 23. The frame 21 is located on the top of the base plate 1, and a through hole is provided in the middle of the frame 21. The drive shaft 23 is rotatably connected in the through hole. The drive shaft 23 can cooperate with the frame 21 through bearings, bushings or other rotating support components to reduce the frictional resistance when the drive shaft 23 rotates. The frame 21 can serve as the installation reference between the fixing component 2, the stop protection component 5 and the adjustment component 6, so that the unwinding position, the stop protection position and the subsequent guiding position of the strip roll are arranged around the same rotation axis.

[0050] Furthermore, a number of fixed rollers 22 are provided on one side of the frame 21, and the fixed rollers 22 are arranged at intervals along the circumference of the frame 21. The fixed rollers 22 are used to install, support or limit the strip roll, so that the strip roll can be stably released as the drive shaft 23 rotates. The fixed rollers 22 can be fixedly connected to the frame 21, or they can be set on the frame 21 through a detachable connection structure, so as to make adaptive adjustments according to strip rolls of different diameters, widths or installation methods. The outer surface of the fixed rollers 22 can be provided with an anti-slip layer, a limiting flange or a guide slope to reduce axial movement or local displacement of the strip roll during rotation.

[0051] Specifically, the support plate 31 is disposed on one side of the frame 21 and is fixedly connected to the base plate 1; the drive motor 32 is disposed on the bottom inner wall of the support plate 31, the output end of the drive motor 32 passes through the support plate 31 and extends to the outside of the support plate 31, and a pulley is sleeved on its output end; the second transmission shaft 34 is rotatably disposed between the top inner walls of the support plate 31, one end of the second transmission shaft 34 passes through the support plate 31 and extends to the outside of the support plate 31, and a pulley is sleeved on its outer wall; the gear belt 33 is connected between the pulley of the drive motor 32 and the pulley of the second transmission shaft 34; the worm 35 is sleeved on the outer wall of the second transmission shaft 34, and the gear 36 is sleeved on the outer wall of the first transmission shaft 23, and the worm 35 and the gear 36 mesh.

[0052] Optionally, the drive motor 32 can be a servo motor, a stepper motor, or a general speed-regulating motor, and the gear belt 33 can be a toothed belt or other belt-shaped transmission component that can achieve stable transmission. A bearing support can be provided between the transmission shaft 34 and the support plate 31. The worm gear 35 and the transmission shaft 34 can rotate synchronously through a key connection, a set screw, or an interference fit. The gear 36 and the transmission shaft 23 can rotate synchronously through a key connection, a spline connection, or a locking sleeve. Through the combination of the gear belt 33, the transmission shaft 34, the worm gear 35, and the gear 36, the output power of the drive motor 32 can be transmitted to the transmission shaft 23.

[0053] Furthermore, the traction component 4 is set on the base plate 1 and located on the conveying path of the strip. The traction component 4 can be a traction roller, guide roller, pressure roller group or traction structure with guide groove. It is used to constrain the path of the strip after it is output from the fixed roller 22, so that the strip keeps the running direction adapted to the telescopic rod 53, column 62, adjusting column 63 and winding head 64. The traction component 4 can cooperate with the traction mechanism of the subsequent wrapping equipment, or it can be used as an auxiliary guiding component in this device to reduce the lateral swing of the strip during high-speed operation.

[0054] Furthermore, the fixed plate 61 is fixedly sleeved on the outer wall of the drive shaft 23 and can rotate synchronously with the drive shaft 23; several columns 62 are set on the outer wall of the fixed plate 61, and the columns 62 are provided with strip passage holes for the strip to pass through; several adjusting columns 63 are set on one side of the fixed plate 61, and the winding head 64 is set between the adjusting columns 63; the fixed plate 61 can be a disc-shaped, annular, or disc-shaped structure with mounting arms, the columns 62 are used to initially guide the strip, the adjusting columns 63 are used to adjust the angle and position of the strip before entering the winding head 64, and the winding head 64 is used to guide the strip to the subsequent wrapped object or wrapping station.

[0055] Understandably, after the drive motor 32 starts, it drives the transmission shaft 34 to rotate through the gear belt 33. The transmission shaft 34 drives the worm gear 35 to rotate. After the worm gear 35 meshes with the gear 36, it drives the transmission shaft 23 to rotate. The transmission shaft 23 synchronously drives the fixed roller 22 and the fixed disk 61 to move. The strip roll is released as it rotates under the support of the fixed roller 22. The released strip passes through the traction component 4, the tape hole at the end of the telescopic rod 53 in the stop protection component 5, the tape hole on the column 62, the adjusting column 63, and the winding head 64 in sequence, and finally enters the wrapping station.

[0056] Example 2:

[0057] It should be noted that this embodiment is based on embodiment 1, and further explains the mechanical self-sensing locking method of the shutdown protection component 5; the focus of this embodiment is to establish a direct mechanical relationship between the tension state of the strip and the locking state of the transmission shaft 23 through the housing 51, ratchet 52, telescopic rod 53, locking pin 54 and return spring 55.

[0058] Specifically, the shutdown protection component 5 includes a housing 51 and a ratchet 52. The housing 51 is fixedly connected to the frame 21 via a support column. The ratchet 52 is disposed inside the housing 51 and sleeved on the outer wall of the drive shaft 23. The ratchet 52 can rotate synchronously with the drive shaft 23. The housing 51 can be disposed on the side of the frame 21 near the strip conveying path, or it can be fixed to the frame 21 in the form of a cover, a seat, or a support box. The housing 51 is not only used to house the ratchet 52, the telescopic rod 53, the locking pin 54, and the return spring 55, but also to provide a sliding guide for the telescopic rod 53, so that the locking pin 54 can move closer to or away from the ratchet 52 in a predetermined direction.

[0059] Furthermore, the housing 51 has several trapezoidal grooves, and the telescopic rod 53 is slidably disposed in each of the trapezoidal grooves. The end of the telescopic rod 53 away from the ratchet 52 has a threading hole for the strip to pass through. The trapezoidal groove can be understood as a guide space that can guide the telescopic rod 53 to move toward or away from the ratchet 52. Its groove wall can limit the sliding direction of the telescopic rod 53 to prevent the telescopic rod 53 from swaying during strip traction or spring reset. The threading hole can be set on the annular guide portion at the outer end or end of the telescopic rod 53 so that the strip can pass through the threading hole under normal tension and exert a traction effect on the telescopic rod 53.

[0060] Furthermore, the shutdown protection assembly 5 also includes a locking pin 54 and a return spring 55. The locking pin 54 is respectively disposed at one end of the telescopic rod 53 near the ratchet 52, and the return spring 55 is respectively sleeved on the outer wall of the telescopic rod 53. The return spring 55 is used to push the telescopic rod 53 toward the ratchet 52 so that the locking pin 54 engages with the ratchet 52. The locking pin 54 can be a pin, a wedge pin, an elastic locking block, or a locking end that can cooperate with the tooth groove of the ratchet 52. The locking pin 54 and the telescopic rod 53 can be fixedly connected, or can be connected by embedding, threaded connection, or pin connection. One end of the return spring 55 can abut against the inner wall of the housing 51, and the other end can abut against the limiting step or locking pin 54 on the telescopic rod 53 so as to push the telescopic rod 53 to return when the strip loses its traction.

[0061] Optionally, a limiting ring, guide sleeve, or anti-detachment stop can also be provided inside the housing 51 to limit the maximum outward and inward movement positions of the telescopic rod 53; an appropriate sliding clearance can be left between the telescopic rod 53 and the trapezoidal groove to ensure that the telescopic rod 53 can still move smoothly when dust, strip debris, or slight assembly errors exist; the tooth profile of the ratchet 52 can be set according to the predetermined rotation direction of the drive shaft 23, so that after the locking pin 54 enters the ratchet 52, it can form a stop in the unwinding direction, thereby preventing the strip roll from continuing to release strip.

[0062] Understandably, when the strip is being conveyed normally and kept taut, the strip passes through the threading hole at the end of the telescopic rod 53. As the strip is pulled along the conveying direction, the strip at the threading hole can exert a pulling or supporting effect on the telescopic rod 53 away from the ratchet 52, keeping the locking pin 54 separated from the ratchet 52, and the return spring 55 in a compressed or stored state. At this time, the drive shaft 23 can drive the ratchet 52 to rotate normally, and the fixed roller 22 and the fixed disc 61 can also complete the unwinding and guiding actions.

[0063] It should be noted that when the strip breaks, loosens, or the tension decreases, the traction effect of the strip on the end hole of the telescopic rod 53 weakens or disappears. The return spring 55 releases its elastic force and pushes the telescopic rod 53 toward the ratchet 52. The telescopic rod 53 drives the locking pin 54 into the tooth groove or stop area of ​​the ratchet 52. After the ratchet 52 is restricted by the locking pin 54, it prevents the drive shaft 23 from continuing to rotate in the unwinding direction.

[0064] Example 3:

[0065] It should be noted that this embodiment is based on embodiment 2, and further explains the multi-position self-sensing protection method; the focus of this embodiment is that by using several trapezoidal grooves and several telescopic rods 53, independent triggering units can be formed for different conveyor belt positions, thereby improving the device's adaptability to multi-strand or multi-path conveyor belts.

[0066] Specifically, the trapezoidal grooves inside the housing 51 can be arranged circumferentially around the ratchet 52, or arranged along different areas of the housing 51 according to the actual conveying path of the strip; each trapezoidal groove is provided with a telescopic rod 53, and each telescopic rod 53 is provided with a corresponding locking pin 54 and a return spring 55, and a strip-passing hole is formed at the end away from the ratchet 52; the telescopic rods 53 can correspond to the strip output from different fixed rollers 22, or correspond to different guiding positions of the same strip in different wrapping paths.

[0067] Furthermore, multiple sets of telescopic rods 53 and locking pins 54 can be arranged facing the same ratchet 52. Since the ratchet 52 is sleeved on the drive shaft 23 and rotates synchronously with the drive shaft 23, when the strip breaks or the tension decreases at any position, the telescopic rod 53 at the corresponding position can drive the locking pin 54 to engage with the ratchet 52 under the action of the return spring 55. Thus, the drive shaft 23 is restricted from continuing to rotate through the same ratchet 52. In this way, it is not necessary to set up a complete brake spindle for each strip. It is only necessary to arrange multiple self-sensing trigger positions around the same ratchet 52 to achieve linkage protection for multiple tension states.

[0068] Optionally, the threading holes of each telescopic rod 53 can be set as round holes, elongated holes, arc-shaped holes, or rectangular holes with rounded corners, depending on the width of the strip and the running angle, to reduce the scraping of the strip edge when passing through; the edge of the threading hole can be provided with a smooth guide surface or a wear-resistant bushing, and the outer end of the telescopic rod 53 can also be provided with a detachable guide ring for replacing worn parts; for strips of different materials, different thicknesses, or different tension requirements, the shutdown protection component 5 can obtain different trigger sensitivities by replacing the return spring 55, adjusting the spring preload, or changing the relative position of the telescopic rod 53 and the threading hole.

[0069] It should be noted that multiple strip positions are guided by the threading holes of the corresponding telescopic rods 53. When all strips are kept under normal tension, each telescopic rod 53 is kept away from the ratchet 52, and each locking pin 54 is not in contact with the ratchet 52, allowing the drive shaft 23 to rotate normally. When any strip breaks or becomes significantly loose, that strip no longer maintains the unlocked position of the corresponding telescopic rod 53. The corresponding return spring 55 pushes the telescopic rod 53 to move, and the corresponding locking pin 54 engages with the ratchet 52. Thus, the ratchet 52 restricts the rotation of the drive shaft 23. Even if other positions still have strips kept under tension, they will stop unwinding because the drive shaft 23 is locked.

[0070] Example 4:

[0071] It should be noted that this embodiment is based on any of the aforementioned embodiments, and further explains the cooperative relationship between the adjustment component 6 and the shutdown protection component 5; the focus of this embodiment is to organize the belt path after the strip is released from the fixed roller 22 into a path that can stably pass through the shutdown protection component 5 through the fixed plate 61, column 62, adjustment column 63 and winding head 64, so that the belt breakage trigger position and the wrapping guide position remain continuously corresponding.

[0072] Specifically, the fixed disk 61 is fixedly sleeved on the outer wall of the drive shaft 23 and can rotate synchronously with the drive shaft 23. Several columns 62 are set on the outer wall of the fixed disk 61. The columns 62 are provided with strip passage holes for the strip to pass through. The strip passage holes can be set along the radial or axial direction of the columns 62. The openings can be provided with rounded corners, guide sleeves or wear-resistant bushings to reduce the wear of the strip when it passes through. Several adjusting columns 63 are set on one side of the fixed disk 61. The adjusting columns 63 can be used to adjust the position of the strip before it enters the winding head 64, and can also be used to guide the incident angle and wrapping angle of the strip.

[0073] Furthermore, the winding head 64 is disposed between several adjusting columns 63. The winding head 64 is coaxially disposed with the object to be wrapped in the wrapping equipment, so that the strip can enter the winding area at a predetermined angle after being adjusted by the adjusting columns 63. The winding head 64 can be provided with a strip passage, guide groove or annular guide surface to keep the strip in a stable posture when it is conveyed at high speed. The fixed plate 61, column 62, adjusting column 63 and winding head 64 can be connected by bolts, snap-fit ​​or integral molding, as long as a stable guiding structure can be formed under the drive of the drive shaft 23.

[0074] It should be noted that after the strip is output from the fixed roller 22, it first passes through the traction member 4 and the end of the telescopic rod 53 through the strip hole, then enters the strip passage hole of the column 62, and enters the winding head 64 after being adjusted by the adjusting column 63. Since the strip passage hole of the telescopic rod 53 is located on the conveying path of the strip from the fixed roller 22 to the adjusting component 6, the strip has completed the tensioning and traction of the stop protection component 5 before entering the wrapping guide position. When the strip is being conveyed normally, the telescopic rod 53 remains unlocked. When the strip breaks or the tension decreases at any point between the fixed roller 22 and the winding head 64, the telescopic rod 53 can promptly lose traction and trigger the locking pin 54 to lock the ratchet 52.

[0075] Furthermore, the adjusting component 6 is not only used to change the strip position, but also, together with the stop protection component 5, defines the effective detection path for the strip tension state; the fixed plate 61 and the drive shaft 23 rotate synchronously, so that the guide path and the unwinding path are established based on the same axis system; the column 62, the adjusting column 63, and the winding head 64 keep the strip in a stable tension direction before entering the wrapping area; the telescopic rod 53 is located on this path, so that the strip state can directly affect the engagement and disengagement relationship between the locking pin 54 and the ratchet 52. Thus, the strip release, tension self-sensing, and wrapping guidance form a continuous and coordinated structure, rather than independent and separate structures.

[0076] When using this invention, the strip roll is first installed on several fixed rollers 22 in the fixed assembly 2, and the strip is then passed through the traction member 4, the strip hole at the end of the telescopic rod 53, the strip hole on the column 62, the adjusting column 63 and the winding head 64 in sequence before entering the wrapping station;

[0077] After the drive motor 32 starts, it drives the gear belt 33 to run. The gear belt 33 drives the second transmission shaft 34 to rotate. The second transmission shaft 34 drives the worm 35 to rotate. After the worm 35 meshes with the gear 36, it drives the first transmission shaft 23 to rotate. The first transmission shaft 23 synchronously drives the fixed disk 61 to rotate, so that the strip roll releases the strip and completes continuous guided conveying through the traction component 4 and the adjustment component 6.

[0078] When the strip is under normal tension, the strip passes through the thread hole at the end of the telescopic rod 53 and exerts a traction force on the telescopic rod 53, so that the telescopic rod 53 overcomes the elastic force of the return spring 55 and stays away from the ratchet 52. The locking pin 54 is separated from the ratchet 52, and the drive shaft 23 can continuously drive the fixed roller 22 and the fixed disc 61 to unwind and guide.

[0079] When the strip breaks, loosens, or its tension decreases, the traction of the strip on the telescopic rod 53 weakens or disappears. The return spring 55 pushes the telescopic rod 53 toward the ratchet 52. The telescopic rod 53 drives the locking pin 54 into the tooth groove of the ratchet 52, so that the ratchet 52 is restricted by the locking pin 54 and prevents the drive shaft 23 from continuing to rotate in the unwinding direction. The fixed roller 22 and the fixed disc 61 then stop releasing and guiding the strip. Thus, after the strip loses its tension, the unwinding source is directly restricted from continuing to run by mechanical locking, reducing the situation of the strip continuing to accumulate, misalign, and entangle after the strip breaks.

[0080] Based on the preferred embodiments of the present invention described above, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
