Description

[0001] This application is a divisional application of the patent application filed on March 28, 2024, with application number 2024103673740, entitled "A feeding device for a packing machine". Technical Field

[0002] This invention relates to the field of automatic packaging technology, and more specifically to a tape feeding and splicing system. Background Technology

[0003] In production, in order to facilitate the storage, transportation, sales, and intermediate processing (such as electroplating and heat treatment) of tubular or strip materials (such as copper tubes, copper strips, aluminum tubes, and aluminum strips), it is often necessary to roll the materials onto a drum. After the materials are rolled up, they need to be bundled and packaged in a timely manner.

[0004] In existing technologies, for situations with high packaging requirements, such as bundling and packaging of coiled metal materials (e.g., coiled copper tubes, copper strips, aluminum tubes, aluminum strips, etc.), or because of requirements on packaging strength, or because the coiled metal materials need to be packaged before being sent to an annealing furnace for annealing, copper or steel strips are required as packaging straps, and metal strapping buckles are needed for binding. During packaging, both ends of the packaging strap must pass through the strapping buckle, and one end of the packaging strap needs to be bent after passing through the buckle to prevent the buckle from slipping off. Then, a locking machine is used to press the buckle tight so that it is pressed against the packaging strap. Finally, a cutting machine is used to cut off the excess packaging strap.

[0005] In existing technologies, automation for strapping and packaging is mostly found in strapless strapping machines. These machines do not use strapping clips but instead weld the two ends of the strapping band together using heat. However, for metal strapping, which requires metal strapping clips, existing automatic strapping machines cannot automate the process, so manual strapping is still the preferred method.

[0006] For situations requiring strapping with buckles and straps, manual strapping involves operations such as taking the buckle, threading the strap, feeding the strap, tightening the strap, clamping the strap (also known as locking or interlocking), and cutting the strap. This process is cumbersome and inefficient, especially the feeding and threading of the strap (feeding means moving the strap in the direction where the binding path needs to be formed, and threading means passing the strap through a specific channel, which is a channel on the existing roll for easy strapping). Because the material is heavy and prone to rolling after being rolled up, to ensure the safety of the binding, the strapping operation is often carried out while the rolled material is still on the roll. The roll restricts the rotation of the material, which facilitates the strapping and ensures safety. However, the presence of the roll means that the strap needs to be fed from one side of the roll to the other, and it must first pass through the threading transition groove on the roll before being inserted into the threading channel to achieve accurate feeding and threading. Under these higher requirements, the already inefficient manual operation becomes even less efficient. Summary of the Invention

[0007] The present invention aims to provide a strapping device for a packing machine to solve the problem of low efficiency caused by manual strapping when using packing buckles and straps for packing.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: A strapping machine feeding device includes a traction assembly for traction and conveying the strapping tape, a guide clamp and a rotary driver. The guide clamp has a guide channel for guiding the strapping tape feeding. The guide clamp is fixedly installed at the output end of the rotary driver. The rotary driver drives the guide clamp to rotate, and the rotating guide clamp is used to change the conveying direction of the strapping tape.

[0009] The principle and advantages of this solution are as follows: When using this solution, the traction component drives the strapping to move or be conveyed. The conveyed strapping moves along the guide channel. In this solution, it is only necessary to rotate the guide clamp at a set angle so that the conveying direction of the strapping can be aligned with the conveyor channel. Then, the strapping is fed by the traction component and guided by the guide clamp to pass through the conveyor channel.

[0010] Preferably, as an improvement, it also includes a lifter for driving the guide clamp to rise and fall.

[0011] Beneficial effects: The lifting mechanism allows for adjustment of the guide clamp's height, making it easier to accurately insert the packing strap into the conveyor channel with fewer adjustments required.

[0012] Preferably, as an improvement, the guide clamp is oscillating relative to the output end of the rotary driver, and a guide seat is connected to the guide clamp. The guide seat is close to the discharge end of the guide clamp and is used to cooperate with adjacent stiffeners on the drum.

[0013] Beneficial effects: Because the tape passage and tape transition groove change slightly with the rotation of the drum, there are generally 2, 4 or 6 tape passages and tape transition grooves on the drum (in the prior art, the tape passage and tape transition groove are one-to-one and the positions are aligned, that is, the port of the tape passage is connected to the tape transition groove). However, it cannot be guaranteed that the drum will stop at the same position every time it rotates, which causes the guide clamp to not be completely aligned with the tape passage, making it difficult to achieve accurate tape insertion.

[0014] This solution improves the probability of the packing strap on the guide clip aligning with the packing strap by setting the guide clip to be able to swing and installing a guide seat on the guide clip. When the guide clip approaches the belt conveyor under the action of the lift, the guide seat guides the approach process.

[0015] Preferably, as an improvement, first elastic elements are symmetrically installed on both sides of the swing center of the guide clamp, one end of the first elastic element is fixed on the guide clamp, and the other end of the first elastic element is fixedly installed on the output end of the rotary driver.

[0016] Beneficial effect: By setting the first elastic element, the guide clamp can automatically reset after each swing due to the first elastic element.

[0017] Preferably, as an improvement, the cross-sectional width of the guide channel gradually decreases from the feed end to the discharge end.

[0018] Beneficial effects: By continuously narrowing the cross-sectional width of the guide channel, the position of the strapping is calibrated, which helps the strapping extending out of the guide channel to be accurately inserted into the strapping channel with the cooperation of the guide seat and the first elastic element, thereby further improving the efficiency of strapping threading.

[0019] Preferably, as an improvement, the guide clamp includes a guide portion and a movable plate. The guide portion is provided with a guide groove and a pusher is installed on the guide portion. The movable plate is installed at the output end of the pusher. The pusher is used to drive the movable plate away from or near the bottom of the guide groove. The guide groove and the movable plate can enclose a guide channel.

[0020] Beneficial effects: When using this solution, the strapping needs to be removed from the feeding device before it is clamped by the strapping buckle. If the enclosing space of the guide channel cannot be released, the strapping cannot be removed. This solution, through the setting of the pusher, can adjust the channel cross-section of the guide channel to facilitate the control of the strapping feeding. On the other hand, when the strapping needs to be removed from the guide channel, the pusher can be controlled to move the movable plate away from the guide part, thereby facilitating the removal of the strapping.

[0021] Preferably, as an improvement, the traction assembly includes a driving wheel and a driven wheel, at least one of which is movable to adjust the distance between the driving wheel and the driven wheel; it also includes a translator that drives the traction assembly and the guide clamp to translate along the width direction of the packing strap, or a swing driver that drives the traction assembly and the guide clamp to rotate away from the packing strap.

[0022] Beneficial effects: The distance between the driving wheel and the driven wheel of the traction component can be adjusted, which can meet the feeding requirements of strapping with different thicknesses. On the other hand, when the distance between the driving wheel and the driven wheel is large enough, it is convenient for the translation device or swing driver to drive the traction component and the guide clamp away from the strapping in a translation or swing manner, so as to prepare for tightening the strapping before the subsequent strapping buckle bites.

[0023] Preferably, as an improvement, the guide seat is slidably connected to the guide clamp, and the guide seat can move closer to or further away from the guide clamp after sliding. A second elastic element is installed between the guide seat and the guide clamp.

[0024] Beneficial effects: In order to avoid hard collision between the guide clamp and the drum during the process of the guide clamp approaching the belt conveyor, a second elastic element is designed so that the guide seat has already contacted the belt conveyor transition groove before the guide clamp contacts the belt conveyor transition groove at the feed end of the belt conveyor during the approach process, thereby reducing the intensity of the impact between the guide seat and the drum and realizing the protection of the belt feeding device when it approaches the belt conveyor.

[0025] Preferably, as an improvement, the guide clip is offset relative to the output center of the rotary driver.

[0026] Beneficial effects: This solution allows the guide clamp to rotate along a longer path, thus enabling the strapping to move along a larger radius of curvature, avoiding the bending of the metal strapping due to an insufficient radius.

[0027] Preferably, as an improvement, the guide clip is equipped with a position monitor, which is used to monitor whether the packing tape has been conveyed to a set position.

[0028] Beneficial effects: When using this solution, the presence of the position monitor enables the monitoring of the strapping feeding position, which facilitates timely control of the corresponding drive mechanism (such as the traction component) to stop the strapping feeding after the strapping accurately passes through the guide channel.

[0029] The present invention also discloses a strap receiving device, including a lifting receiving arm, a receiving clamp installed on the receiving arm, a receiving channel provided on the receiving clamp, the receiving channel of the receiving clamp can be enlarged or reduced, and the receiving channel of the receiving clamp can hold the strapping when it is reduced, and the feeding end of the receiving channel is provided with a trumpet-shaped receiving port.

[0030] Beneficial effects: The strapping device in this solution is used to clamp the strapping that has passed through the strapping channel, which facilitates the subsequent pulling of the strapping by the lifting function of the receiving arm, thereby improving the automation of strapping.

[0031] Preferably, as an improvement, a second rotary driver is installed on the receiving arm, and the receiving clamp is installed at the output end of the second rotary driver. The second rotary driver is used to drive the receiving clamp to rotate.

[0032] Beneficial effects: The second rotary driver in this solution allows the discharge end of the receiving channel of the receiving clamp to change direction. As the receiving clamp moves the strapping towards the strapping buckle, the second rotary driver can rotate the end of the strapping. This allows the strapping to form an enclosing posture and prepares for the end of the strapping to be inserted into the strapping buckle again, further improving the degree of automation.

[0033] Preferably, as an improvement, a second pusher is also installed on the output end of the second rotary driver. The receiving clamp includes a fixed clamp plate and a movable clamp plate. The fixed clamp plate is fixed on the output end of the second rotary driver, and the second pusher is used to drive the movable clamp plate away from or towards the fixed clamp plate.

[0034] Beneficial effects: The design of this solution allows the receiving channel of the receiving clamp to be enlarged or reduced to meet the clamping and releasing requirements of the strapping.

[0035] The present invention also discloses a tape feeding and receiving system, including the tape feeding device of the packing machine and the tape receiving device. Attached Figure Description

[0061] The following detailed description illustrates the specific implementation method: Example 1 Combination Figures 2 to 9As shown, a strapping machine's feeding device includes a lifter 1, with a mounting base 11 fixed to the output end of the lifter 1. A translator 2 is fixed on the mounting base 11. The lifter 1 is used to drive the translator 2 to move vertically. The output end of the translator 2 can move horizontally. In this embodiment, the lifter 1 is a linear module, and the translator 2 is a linear actuator, specifically a ball screw structure. A rotary actuator 21 is fixed to the output end of the translator 2, and a mounting plate 211 is fixed to the output end of the rotary actuator 21. A traction component 3 and a guide clamp 4 are mounted on the mounting plate 211. In this embodiment, the rotary actuator 21 is a servo motor, and the rotary actuator 21 drives the mounting plate 211 at the output end to rotate via belt drive.

[0062] The traction assembly 3 is used to pull and convey the packing strap. The traction assembly 3 includes a driving wheel 31 and a driven wheel 32. At least one of the driving wheel 31 and the driven wheel 32 is movable to adjust the distance between the driving wheel 31 and the driven wheel 32. In this embodiment, the driving wheel 31 is rotatably connected to the mounting plate 211. The driving wheel 31 is equipped with a servo motor, which is fixed on the mounting plate 211 and used to drive the driving wheel 31 to rotate. The driven wheel 32 is mounted on a linear driver A33. The linear driver A33 is used to drive the driven wheel 32 away from or closer to the driving wheel 31. The linear driver A33 is fixed on the mounting plate 211.

[0063] Both the traction assembly 3 and the guide clamp 4 are eccentrically positioned about the output center of the rotary driver 21 (in this embodiment, the output center is also the rotation center of the mounting plate 211). The rotary driver 21 is used to drive the guide clamp 4 to rotate, and the rotating guide clamp 4 is used to change the conveying direction of the packing tape.

[0064] The guide clamp 4 is capable of swinging. The guide clamp 4 is provided with a guide channel. The cross-sectional width of the guide channel gradually decreases from the feed end to the discharge end to facilitate the insertion of the packing strap into the guide channel and to limit the position of the packing strap. The swing center of the guide clamp 4 is located at the center of the width of the guide channel and the swing axis of the guide clamp 4 is perpendicular to the guide channel. Specifically, a support block is fixed on the mounting plate 211, and the guide clamp 4 is rotatably connected to the support block through the swing axis.

[0065] The guide clamp 4 includes a guide part 41 and a movable plate 42. The guide part 41 is provided with a guide groove 411, which has a U-shaped cross-section. The left and right side walls of the U-shaped guide groove 411 have different heights, with the side wall closer to the mounting plate 211 being higher. The guide part 41 is located on the inner side relative to the movable plate 42 (that is, the guide part 41 is closer to the swing center of the guide clamp 4). The swing shaft is located on the side near the feed end of the guide channel. The guide part 41 is rotatably connected to the support block. A pusher 43 (i.e., a pusher) is fixedly installed on the side wall of the higher guide part 41. The pusher 43 is installed on the high side wall of the U-shaped section, and the movable plate 42 is installed on the output end of the pusher 43. The pusher 43 is used to drive the movable plate 42 away from or near the bottom of the guide groove 411. After the movable plate 42 is close to the bottom of the guide groove 411, the guide groove 411 and the movable plate 42 enclose a guide channel. In this embodiment, the pusher 43 is a cylinder. After the movable plate 42 is away from the guide groove 411, a space is left between the top of the low side wall of the guide groove 411 and the movable plate 42 for the packing strap to move freely, which facilitates the subsequent removal of the packing strap from the guide clamp 4.

[0066] To ensure that the guide clamp 4 can return to its original position after swinging, first elastic elements 44 are symmetrically installed on both sides of the guide channel of the guide clamp 4. One end of the first elastic element 44 is fixed on the guide clamp 4, and the other end of the first elastic element 44 is fixedly installed on the support block or mounting plate 211. The two first elastic elements 44 are symmetrically arranged about the swing axis.

[0067] In order to ensure that the end of the packing strap can be aligned with the tape-threading transition groove 101 on the drum 10 before feeding, a guide seat 45 is connected to the cantilever end of the guide clamp 4. The guide seat 45 is used to cooperate with the adjacent stiffening plate 102 on the drum 10. The guide seat 45 can slide into the space between the adjacent stiffening plates 102 of the drum 10.

[0068] To avoid hard contact between the tape feeding device and the roll 10, the guide seat 45 is slidably connected to the guide clamp 4. After sliding, the guide seat 45 can move closer to or away from the guide clamp 4. A second elastic element 46 is installed between the guide seat 45 and the guide clamp 4. Both the first elastic element 44 and the second elastic element 46 are springs. The second elastic element 46 is used to give the guide seat 45 a pulling force to move closer to the guide clamp 4.

[0069] In order to reduce the wear of the guide seat 45 and reduce the friction between the guide seat 45 and the upper stiffening plate 102 of the drum 10, wear-resistant plastic blocks 451 are detachably installed on both sides of the guide seat 45. The plastic blocks 451 are used to contact the stiffening plate 102.

[0070] To limit the length of the packing strap extending out of the guide channel, a position monitor 47 is installed on the guide clamp 4. The position monitor 47 is used to monitor whether the packing strap has been conveyed to the set position. In this embodiment, an extension rod 48 is fixedly installed on the guide clamp 4 (a sliding frame 49 is fixed on the extension rod 48, the guide seat 45 slides on the sliding frame 49, one end of the second elastic member 46 is fixed to the end of the guide seat 45, and the other end is fixed to the sliding frame 49 (the projection of the sliding frame 49 is T-shaped)). The extension rod 48 faces the guide channel, and the position monitor 47 is installed at the end of the extension rod 48. The position monitor 47 is a photoelectric sensor. A detection hole is opened on the extension rod 48, and the light from the photoelectric sensor can pass through the detection hole. When the packing strap blocks the detection hole, the photoelectric sensor sends a signal to the controller, thereby controlling the servo motor on the traction assembly 3 to stop rotating after a delay, ensuring that the extension length of the packing strap is sufficient to facilitate the subsequent packing strap being placed on the threading transition groove 101 on the drum 10 after rotating with the rotary driver 21.

[0071] A tape feeding method for a packing machine includes the following steps: S1. The packing strap passes through the traction assembly 3 and is inserted into the guide channel.

[0072] S2. Start the traction component 3, so that the traction component 3 drives the packing strap to move along the guide channel until the packing strap completely passes through the guide channel and extends a section beyond the guide channel, then stop the traction of the traction component 3.

[0073] S3. Control the rotary driver 21 to drive the output center to rotate, so that the end of the packing strap rotates synchronously with the guide clamp 4, in preparation for the packing strap to be aligned with the tape passage 20.

[0074] S4. Start the control lift 1 so that the guide clamp 4 approaches the tape-feeding transition groove 101 of the drum 10. This step S4 is performed after or simultaneously with step S3. During steps S3 and S4, the feeding end of the packing tape is always in a state where it can be pulled out freely.

[0075] As the guide clip 4 gradually approaches the tape-threading transition groove 101, the guide seat 45 on the guide clip 4 also gradually inserts between the adjacent stiffeners 102 of the roll 10, forming a guide for the approaching process of the guide clip 4, ensuring that the end of the packing tape extending from the guide clip 4 can accurately fall into the tape-threading transition groove 101.

[0076] S5. After the strapping falls into the transition groove and contacts the bottom of the transition groove, stop the rotation drive 21 and the lift 1, and feed the strapping through the traction component 3 until the strapping is inserted into the belt passage 20.

[0077] After the strapping tape has completely passed through the tape passage 20 and been reinserted into the strapping buckle by other devices on the strapping machine, in order to ensure the strapping tape is taut and the subsequent strapping buckle engages, the control mover 2 moves the traction component 3 and guide clamp 4 on the mounting plate 211 horizontally away from the strapping tape, reserving space for subsequent operations of the strapping tape.

[0078] This embodiment realizes automatic feeding and threading of the strapping, which greatly improves the automation of the strapping and buckle packaging and helps to improve packaging efficiency.

[0079] Example 2 Combination Figure 10 and Figure 11 Compared to Embodiment 1, in order to facilitate the translation of the guide clamp to meet the needs of drums of different widths, the tape feeding device in this embodiment also includes a transverse driver 30. The lifting device 1 is installed at the output end of the transverse driver 30. The transverse driver 30 drives the lifting device 1 to move along the axial direction of the drum 10. In this embodiment, the transverse driver 30 includes a motor 301, a gear 302 and a transverse moving seat 303. The motor 301 is fixed on the transverse moving seat 303, and the lifting device 1 is also fixed on the transverse moving seat 303. The transverse moving seat 303 slides on the frame (the frame is fixedly installed) in a direction parallel to the axial direction of the drum 10. The gear 302 is fixedly installed on the output shaft of the motor 301. A rack is fixed on the frame. The length direction of the rack is parallel to the axial direction of the drum 10. The gear 302 meshes with the rack so that after the motor 301 is started, the gear 302 meshes with the fixedly installed rack, thereby causing the transverse driver 30 to drive the entire tape feeding device to move along the axial direction parallel to the axial direction of the drum 10.

[0080] Example 3 Combination Figures 12 to 15 A strapping receiving device is located on the discharge end side of a strapping channel to catch the strapping passing through the channel. It includes a lifting receiving arm 5, which is driven to rise and fall by a receiving lifter. The receiving lifter is a vertically arranged linear module. A second rotary driver 51 is mounted on the receiving arm 5. An output plate 51 is fixed to the output end of the second rotary driver 51. A receiving clamp 6 is fixed to the output plate 511. The receiving clamp 6 includes a fixed clamping plate 61, a movable clamping plate 62, and a second pusher 63. The fixed clamping plate 61 is fixed to the output plate 511, and the second pusher 63 is fixed to the output plate 511. The movable clamping plate 62 is fixed to the output end of the second pusher 63. The second pusher 63 is used to move the movable clamping plate 62 away from or closer to the fixed clamping plate 61. A receiving channel is formed between the movable clamping plate 62 and the fixed clamping plate 61. The movement of the movable clamping plate 62 allows the receiving channel of the receiving clamp 6 to expand or shrink to meet the clamping and releasing requirements of the strapping.

[0081] The feed end of the movable clamp 62 has a guiding structure so that the feed end of the receiving channel forms a funnel-shaped receiving port to reduce the difficulty of receiving materials.

[0082] To ensure that the receiving device does not affect the tension of the strapping after it is inserted into the strapping buckle, a second translation device 52 or a second swing driver is provided between the receiving arm 5 and the second rotary driver 51. The second translation device 52 is used to drive the second rotary driver 51 and the receiving clamp 6 to translate along the width direction of the strapping, so that the strapping can be moved out of the receiving channel of the receiving clamp 6. The second swing driver is used to drive the second rotary driver 51 and the receiving clamp 6 to swing away from the strapping, thereby providing space for the tension of the strapping. The attached figure of this embodiment shows the second rotary driver 51 and the receiving clamp 6 being translated by the second translation device 52.

[0083] The strapping device in this embodiment is used to clamp the strapping that has passed through the strapping channel, so that the strapping can be pulled by the lifting function of the receiving arm 5 in the future, thereby improving the automation of the strapping.

[0084] The second rotary driver 51 in this embodiment allows the direction of the discharge end of the receiving channel of the receiving clamp 6 to be changed. As the receiving clamp 6 moves towards the packing buckle while holding the packing strap, the end of the packing strap can be rotated by the second rotary driver 51. This allows the packing strap to form an enclosing posture and also prepares for the end of the packing strap to be inserted into the packing buckle again, further improving the degree of automation.

[0085] In addition, to improve the accuracy of the strapping tape being fed into the funnel-shaped receiving port of the receiving clamp 6 after it passes through the tape passage 20, a tape receiving guide block is provided on the roll 10. The tape receiving guide block has an arc-shaped guide surface. One end of the guide surface is used to connect with the tape passage, and the other end of the guide surface is used to connect with the receiving port of the receiving clamp 6.

[0086] In this embodiment, to facilitate the movement of the tape receiving device along a direction parallel to the drum axis, a transverse mover is also provided on the frame. The receiving lifter is fixed at the output end of the transverse mover, and the structure of the transverse mover is the same as in embodiment two.

[0087] Example 4 Combination Figure 16 Further optimization of Embodiment 3 includes setting a receiving groove 611 on the fixed clamping plate 61 of the receiving clamp 6. The movable clamping plate 62 can move away from or near the bottom of the receiving groove 611 under the drive of the second pusher 63. The width of the receiving groove 611 gradually narrows as it gets closer to the discharge end. The narrowing width limits the position of the extended end of the packing strap, ensuring that the packing strap can be inserted into the packing buckle more accurately and quickly in the future.

[0088] Example 5 Combination Figure 17 A belt feeding and receiving system includes a belt feeding device according to Embodiment 1 / Embodiment 2 and a belt receiving device according to Embodiment 3 / Embodiment 4. The belt feeding device is located on the feeding end side of the belt conveyor 20, and the belt receiving device is located on the discharging end side of the belt conveyor 20.

[0089] In this embodiment, the traction component 3 of the feeding device feeds the strapping tape onto the guide clamp 4. The guide clamp 4 aligns the strapping tape with the tape passage 20. The traction component 3 feeds the tape, so that the strapping tape passes through the tape passage 20 and is caught by the receiving clamp of the receiving device. Under the lifting and lowering of the receiving arm 5, the strapping tape is driven to wrap around the material to form a ring, which facilitates the subsequent strapping tape to be inserted into the strapping buckle and helps to improve the degree of automation.

[0090] Example 6 Combination Figure 19 and Figure 20 An application of a tape feeding device includes using the tape feeding device of the packing machine described in Embodiment 1 on an automatic packing machine for feeding the packing tape in the automatic packing machine.

[0091] This embodiment also discloses an automatic strapping machine, including a strapping tape feeding device, a strapping tape dispenser 7, a locking device 8, a strapping buckle release device 9, and a strapping tape receiving device. The locking device is located between the strapping tape dispenser 7 and the strapping feeding device, and the strapping tape receiving device is located between the strapping tape dispenser 7 and the locking device. The strapping tape dispenser 7 is used to dispense or retract the strapping tape. The locking device 8 includes a tensioning mechanism 81, a biting mechanism 82, and a cutting blade 83. The tensioning mechanism 81 is used to drive the strapping tape forward or backward. When the tape is backward, the strapping tape dispenser 7 winds up the excess strapping tape. The backward process is a process of tightening the space enclosed by the strapping tape. The biting mechanism 82 is used to bite the strapping buckles with double-layer strapping tape. After the strapping buckles are bitten, the cutting blade 83 cuts off the excess strapping tape. The strapping buckle release device 9 is used to push the strapping buckles to be used to a ready position. This ready position allows the tensioning mechanism 81 to easily pass the end of the strapping tape through the strapping buckle in the ready position.

[0092] The entire process of automatic strapping is as follows: the strapping tape dispenser 7 releases the strapping tape. Under the forward feeding of the tensioning mechanism 81 of the locking device 8, the strapping tape passes through the strapping buckle released by the strapping buckle release device 9 and continues to be fed forward into the feeding device. The feeding device drives the strapping tape to be inserted into the tape passage 20. The traction component 3 and the tensioning mechanism 81 continue to feed the tape until it extends out from the discharge end of the tape passage 20. The strapping tape then enters the receiving device, where it is pulled at the end. The receiving device then pulls the strapping tape closer to the locking device 8. The strapping band is released from the strapping buckle 9 until the end of the strapping band extending from the strapping receiving device is inserted into the ready-to-use strapping buckle on the strapping buckle release device 9, completing the wrapping of the strapping band; then the rotating plate on the strapping buckle release device 9 bends one end of the strapping band that passes through the strapping buckle to the outside of the strapping buckle, so that the strapping band is fastened on the strapping buckle; then the tensioning mechanism 81 drives the strapping band to retract to tighten the wrapping space of the strapping band until the strapping band is taut; finally, the biting mechanism 82 bites the strapping buckle, and the cutting blade 83 cuts off the excess part of the strapping band, completing the fully automatic packaging of the strapping band and strapping buckle.
