Description

Technical Field

[0001] The present invention relates to the technical field of cable manufacturing equipment, in particular to a wrapping mechanism and a wrapping machine. Background Art

[0002] During the cable production process, the wrapping process uses a wrapping machine to wrap tape (such as mica tape) on the cable surface to achieve insulation, protection and other functions.

[0003] The wrapping mechanisms of existing wrapping machines are cumbersome and time-consuming to replace the wrapping tape roll. For example, the mica tape wrapping machine disclosed in Patent Publication No. CN218647696U requires the sequential disassembly of multiple components, including the fixing nut, limit plate, and spring, to replace the wrapping tape roll. The spring pressure must then be readjusted during installation, resulting in a lengthy replacement process and a significant impact on production efficiency.

[0004] Furthermore, to adjust the wrapping angle, the aforementioned wrapping machine uses a retaining bolt to secure the wrapping rod, but this structure is less stable. During the wrapping process, the wrapping rod is affected by factors such as vibration, centrifugal force, and the tension of the wrapping tape. The retaining bolts can easily loosen, causing the wrapping rod to shift in angle, resulting in an unstable wrapping angle and affecting the cable wrapping quality. Summary of the Invention

[0005] Based on this, it is necessary to provide a wrapping mechanism and a wrapping machine to address the problems in the existing technology of long-time replacement of wrapping tape rolls and unstable fixation of wrapping rods, so as to achieve rapid replacement of wrapping tape rolls and stable wrapping of the wrapping mechanism.

[0006] In order to achieve the above-mentioned purpose, the present invention provides a wrapping mechanism, including a quick-release mechanism, a swivel seat, a plug seat, a one-way reduction transmission assembly, and a radial locking mechanism. The one-way reduction transmission assembly includes an active rotating member and a driven rotating shaft connected to the one-way reduction transmission thereof, the driven rotating shaft and the active rotating member are both rotatably connected to the swivel seat, and the driven rotating shaft is fixedly connected to the plug seat; the quick-release mechanism includes an axial locking mechanism and a wrapping rod; a cavity is provided in the plug seat, the cavity includes a positioning section that cooperates with the conical surface of the wrapping rod, a locking member is fixed on the active rotating member, and a locking member has several locking grooves on the locking member; the axial locking mechanism includes an axial locking head connected to the wrapping rod, the axial locking head is engaged with the locking groove to limit the rotation of the locking member; the radial locking mechanism includes a radial locking rod that is slidably connected to the plug seat and can move radially along the wrapping rod, a radial limiting groove is provided on the wrapping rod, and the radial locking rod is engaged with the radial limiting groove to limit the axial movement of the wrapping rod in the cavity.

[0007] Optionally, the one-way reduction transmission assembly further includes a first transmission shaft, a first worm wheel, a worm, a second worm wheel, a first gear, and a second gear. The first transmission shaft and the worm are both rotatably connected to the epicyclic seat, the first worm wheel and the first gear are both fixedly mounted on the first transmission shaft, the second gear is fixedly mounted on the worm, and the second worm wheel is fixedly mounted on the driven shaft. The active rotating member is a hollow worm coaxially sleeved on the driven shaft, the first worm wheel is meshed with the active rotating member, the first gear is meshed with the second gear, and the worm is meshed with the second worm wheel. The multi-stage worm gear and gear transmission structure realizes one-way reduction, which can significantly reduce the speed of the driven shaft. Even if the locking member fine-tunes the angle, the rotation deviation of the wrapping rod is extremely small, reducing the impact on the wrapping quality and ensuring the wrapping accuracy.

[0008] Optionally, the one-way reduction transmission assembly further comprises a hand wheel, which is mounted on the active rotating member. The provision of the hand wheel facilitates manual driving of the active rotating member to rotate.

[0009] Optionally, a coaxial through-hole is defined within the wrapping rod, and the axial locking mechanism further comprises an axial locking rod and a first elastic member. The axial locking rod is slidably mounted within the through-hole. An axial locking head is fixed to one end of the axial locking mechanism. One end of the first elastic member is connected to the axial locking head, and the other end is connected to the wrapping rod. The first elastic member continuously applies a thrust to the locking head, ensuring that it is stably engaged in the locking groove, thereby preventing the active rotating member from rotating due to external forces such as vibration. The design of the axial locking rod provides a structural basis for disengaging the locking head when adjusting the wrapping angle.

[0010] Optionally, the axial locking rod extends through a through hole at one end away from the axial locking head and is equipped with an axial handle. The axial locking rod is radially provided with a pin hole at the end near the axial handle. In a natural state, under the thrust of the first elastic member, the pin hole is located within the through hole. When the pin hole extends out of the through hole, the axial locking head is disengaged from the locking member. The design of the axial handle and pin hole allows the operator to easily release or restore the axial lock by simple operations such as pulling the handle and inserting a pin, thereby facilitating the adjustment and fixing of the wrapping angle and improving operational convenience.

[0011] Optionally, the axial locking head is a rotating body structure, and the axial locking head is coaxially arranged with the wrapping rod. The rotating body structure is adapted to the sliding section of the circular cross-section of the cavity, and no angle adjustment is required when installing the quick release mechanism, and the axial locking head can be directly inserted, which simplifies the installation process and improves the installation efficiency of the quick release mechanism.

[0012] Optionally, the radial locking mechanism further includes a second elastic member, a pressure plate, and a fixing frame, wherein the fixing frame is fixedly connected to the socket, and the pressure plate is fixedly mounted on the radial locking rod. One end of the second elastic member is connected to the fixing frame, and the other end is connected to the pressure plate. The socket is provided with a radial hole communicating with the cavity, and the radial locking rod is slidably connected to the radial hole. The radial locking rod has an inclined surface on the end facing the cavity. The inclined surface design facilitates insertion of the wrapping rod into the cavity. The second elastic member continuously applies thrust to the pressure plate and radial locking head, ensuring that the radial locking head is stably inserted into the cavity, achieving rapid radial locking and unlocking of the wrapping rod. Combined with axial locking, this ensures that the wrapping rod is stable and does not shake during the wrapping process.

[0013] Optionally, the wrapping rod includes a first frustum segment, a second frustum segment, and a round rod segment, which are sequentially connected. The minimum diameter of the first frustum segment is smaller than the minimum diameter of the second frustum segment, and a radial limit groove is provided on the second frustum segment. The multi-stage frustum structure formed by the first and second frustum segments guides and aligns the wrapping rod when inserted into the cavity, facilitating quick positioning, reducing alignment time during installation, and improving the efficiency of assembly and disassembly of the quick-release mechanism.

[0014] Optionally, the round rod segment is provided with a flange; the quick-release mechanism further comprises a first baffle, a second baffle, a third elastic member, a nut, and a rotary handle. The first baffle, the second baffle, and the third elastic member are all mounted on the round rod segment, the nut is threadedly connected to the round rod segment, the rotary handle is fixed to the nut, and the ends of the third elastic member respectively abut the second baffle and the nut. By rotating the rotary handle to adjust the position of the nut, the tension of the wrapping tape can be flexibly adjusted to avoid slipping due to excessive looseness or breakage due to excessive tightening. The flange prevents the first baffle from falling out, and the third elastic member elastically clamps the wrapping tape, ensuring that the wrapping tape is securely installed.

[0015] In the second aspect, the present invention also provides a wrapping machine, including a machine body, a wire tube, and a rotating frame. The wire tube is fixedly installed on the machine body, and the rotating frame is rotatably installed on the wire tube and is coaxially arranged with the wire tube. It also includes any of the above-mentioned wrapping mechanisms, and the wrapping mechanisms are arranged in two and are distributed circumferentially along the axial direction of the wire tube. The revolving seat is fixedly connected to the rotating frame.

[0016] Compared with the existing technology, this technical solution has at least one of the following beneficial effects:

[0017] By setting up two sets of quick-release mechanisms and using them alternately, the quick-release mechanisms can be directly replaced when changing rolls. The wrapping rod and the socket are matched through the conical surface to achieve precise radial positioning. The radial locking rod automatically snaps into the radial limit groove, which can quickly lock the wrapping rod, greatly shortening the roll changing time, reducing downtime, and improving production efficiency.

[0018] The axial locking head is connected to the locking piece to form a mechanical limit, locking the active rotating part and the driven rotating shaft, so that the adjusted wrapping angle is automatically locked to resist interference such as vibration, centrifugal force, and wrapping tension;

[0019] The driving rotating part and the driven rotating shaft are driven by reduction gear transmission. In the process of the axial locking head clamping the locking part, fine-tuning the angle of the driving rotating part will not cause the driven rotating shaft and the socket to rotate too much, and can reduce the deviation of the wrapping angle.

DETAILED DESCRIPTION

[0028] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] See also Figures 1 to 7 , this application embodiment provides a wrapping machine, please refer to Figure 6 The wrapping machine includes a body 700, a wire tube 800, a rotating frame 900 and a wrapping mechanism. The wire tube 800 is fixedly installed on the body 700, and the rotating frame 900 is rotatably installed on the wire tube 800 through a bearing. The wrapping mechanism is set to two and is distributed circumferentially along the axial direction of the wire tube 800.

[0030] The cable passes through conduit 800. The inner wall of conduit 800 restricts radial movement of the cable during wrapping, preventing swaying during wrapping and affecting wrapping accuracy. A rotating frame 900 drives the two wrapping mechanisms to rotate synchronously around conduit 800, spirally wrapping the tape on the wrapping rod 120 around the cable. By adjusting the rotation speed to match the cable feed speed, the wrapping angle and pitch can be precisely controlled.

[0031] A power shaft is rotatably mounted on the machine body 700 via a bearing, a driving pulley is mounted on the power shaft, and a driven pulley is mounted on the rotating frame 900. The driving pulley and the driven pulley are driven by a transmission belt. The power shaft is connected to an external power source, and the power shaft is driven to rotate by an external power source such as a motor. The power shaft drives the driven pulley and the rotating frame 900 to rotate through the driving pulley and the transmission belt.

[0032] See also Figures 1 to 5 The wrapping mechanism includes a quick-release mechanism 100, a swivel seat 200, a plug-in seat 300, a one-way reduction transmission assembly 400, and a radial locking mechanism 500.

[0033] The swivel seat 200 is fixedly connected to the rotating frame 900 , and the fixed connection can be achieved by welding, or a rigid connection can be achieved with the rotating frame 900 by fasteners such as bolts.

[0034] See also Figure 1 and Figure 5 The one-way reduction transmission assembly 400 includes a driving rotating member 401, a driven rotating shaft 402, a first transmission shaft 403, a first worm gear 404, a worm 405, a second worm gear 406, a first gear 407, a second gear 408, and a handwheel 409. The first transmission shaft 403 and the worm 405 are both rotatably connected to the revolving seat 200 through bearings. The first worm gear 404 and the first gear 407 are both fixedly mounted on the first transmission shaft 403, the second gear 408 is fixedly mounted on the worm 405, and the second worm gear 406 is 6 is fixedly mounted on the driven rotating shaft 402; wherein the active rotating member 401 is a hollow worm coaxially sleeved on the driven rotating shaft 402, the first worm gear 404 is meshed and connected with the active rotating member 401, the first gear 407 is meshed and connected with the second gear 408, the worm 405 is meshed and connected with the second worm gear 406, the driven rotating shaft 402 and the active rotating member 401 are both rotatably connected with the revolving seat 200, the driven rotating shaft 402 is fixedly connected with the socket 300, and the handwheel 409 is mounted on the active rotating member 401.

[0035] In some other embodiments, the second worm gear 406 can be replaced by a bevel gear, and the worm 405 can be replaced by an optical axis. A bevel gear is also installed on the optical axis. The two bevel gears are meshed and connected, and a one-way reduction transmission connection between the active rotating member 401 and the driven rotating shaft 402 can also be achieved, but the reduction ratio will be reduced.

[0036] The worm gear structure described above achieves a one-way reduction transmission connection between the active rotating member 401 and the driven rotating shaft 402, meaning that the active rotating member 401 can unidirectionally drive the driven rotating shaft 402 to rotate at a reduced speed. Specifically, the active rotating member 401 is driven by the handwheel 409. Since the active rotating member 401 is a hollow worm, it drives the first worm gear 404, the first transmission shaft 403, and the first gear 407. The first gear 407 drives the second gear 408 and the worm gear 405. The worm gear 405 then drives the second worm gear 406, the driven rotating shaft 402, and the connector 300.

[0037] To improve the installation stability of the driven shaft 402, a reinforcing plate 210 can be fixedly mounted on the swivel seat 200. The end of the driven shaft 402 extending from the socket 300 is rotatably connected to the reinforcing plate 210 via a bearing. This effectively supports both ends of the driven shaft 402, preventing the end of the driven shaft 402 extending from the swivel seat 200 from being subjected to excessive radial force due to connection with the socket 300 and the quick release mechanism 100, thereby preventing bending or breaking.

[0038] The quick release mechanism 100 comprises an axial locking mechanism 110 and a taping rod 120. The taping reel is mounted on the taping rod 120.

[0039] See also Figure 1 、 Figure 3 and Figure 4 A cavity 310 is provided in the connector 300, and the cavity 310 includes a positioning section 311 that cooperates with the conical surface of the wrapping rod 120. When the wrapping rod 120 is inserted into the cavity 310, the outer wall of the wrapping rod 120 coincides with the inner wall of the positioning section 311. The mating surfaces of the two are conical surfaces, which can form surface contact, reduce assembly clearance, and ensure accurate radial positioning.

[0040] See also Figure 3 A locking member 600 is fixed to the active rotating member 401. The locking member 600 is located in the cavity 310 and has a plurality of locking grooves 610. To facilitate the locking member 600 to enter the cavity 310, a circular opening is provided on the socket 300 for the locking member 600 to enter the cavity 310. An end cap is fixed to the circular opening by bolts.

[0041] In this embodiment, the locking member 600 is a cylindrical gear, and the locking groove 610 is the tooth gap of the cylindrical gear; optionally, the locking member 600 can also be a disk with a plurality of locking grooves 610 provided on the outer edge of the disk.

[0042] The axial locking mechanism 110 includes an axial locking head 111 connected to the wrapping rod 120 . The axial locking head 111 engages with the locking groove 610 to restrict the rotation of the locking member 600 .

[0043] The axial locking mechanism 110 locks the locking member 600 in a mechanically clamping manner through the axial locking head 111, preventing the locking member 600 and the active rotating member 401 from rotating, so that the wrapping rod 120 maintains a fixed angle during the wrapping process, and preventing the active rotating member 401 from rotating due to factors such as vibration and centrifugal force during the wrapping process, resulting in a deviation in the wrapping angle.

[0044] See also Figure 1 and Figure 5 The radial locking mechanism 500 includes a radial locking rod 510 that is slidably connected to the socket 300 and can move radially along the wrapping rod 120. A radial limiting groove 121 is provided on the wrapping rod 120. The radial locking rod 510 is engaged with the radial limiting groove 121 to limit the axial movement of the wrapping rod 120 in the cavity 310.

[0045] When the wrapping rod 120 is inserted into the positioning section 311 of the cavity 310, the positioning section 311 cooperates with the conical surface of the wrapping rod 120 to limit the radial movement of the wrapping rod 120, and the radial locking rod 510 is inserted into the radial limit groove 121 to limit the axial movement of the wrapping rod 120, so that the wrapping rod 120 is fixedly connected to the socket 300, avoiding the wrapping rod 120 from shaking due to external forces such as centrifugal force during the wrapping process, and ensuring the stability of the wrapping trajectory.

[0046] It should be noted that the wrapping mechanism of this embodiment is provided with two quick-release mechanisms 100 . When one of the quick-release mechanisms 100 is installed on the socket 300 for wrapping operation, the other quick-release mechanism 100 is installed with the wrapping tape reel for standby use.

[0047] In this way, when the wrapping tape roll needs to be replaced, the radial locking rod 510 is driven away from the radial limiting groove 121 so that the radial locking rod 510 no longer engages the wrapping rod 120. Then the quick release mechanism 100 is removed and the spare quick release mechanism 100 is inserted into the cavity 310. By engaging the radial locking rod 510 with the radial limiting groove 121, the wrapping tape roll can be quickly replaced, which greatly shortens the replacement time and improves the cable production efficiency.

[0048] The worm gear self-locking structure can ensure that the angle of the socket 300 remains fixed when the quick release mechanism 100 is disassembled and assembled without external interference.

[0049] Since the locking grooves 610 need to be arranged at intervals, if any locking groove 610 on the locking piece 600 may not be accurately facing the axial locking head 111, that is, the axial locking head 111 may not be able to directly engage with the locking groove 610, it is necessary to turn the hand wheel 409 to fine-tune the angle of the locking piece 600 so that the axial locking head 111 is engaged with the locking groove 610.

[0050] Alternatively, the angle of the locking piece 600 may not be fine-tuned, and the wrapping operation may be performed directly in the initial state where the axial locking head 111 is not engaged with the locking groove 610. During the wrapping process, when the active rotating piece 401 rotates under the action of external forces such as vibration, it will drive the locking piece 600 to rotate, so that the axial locking head 111 is engaged with the locking groove 610.

[0051] The multi-stage reduction transmission between the active rotating member 401 and the first worm gear 404, and between the worm 405 and the second worm gear 406, significantly reduces the rotational speed of the driven rotating shaft 402. For example, the transmission ratios between the active rotating member 401 and the first worm gear 404, and between the worm 405 and the second worm gear 406, are both designed to be 10:1, and the locking grooves 610 are designed to be spaced 10 degrees apart on the circumference of the locking member 600. Thus, assuming that the axial locking head 111 is located between the two locking grooves 610, the locking member 600 only needs to rotate 5 degrees to engage the axial locking head 111 with the locking grooves 610. When the locking member 600 rotates 5 degrees, the multi-stage reduction transmission between the active rotating member 401 and the first worm gear 404, and between the worm 405 and the second worm gear 406, causes the driven rotating shaft 402, the insertion groove, and the wrapping rod 120 to rotate only 0.05 degrees, minimizing the deviation in the wrapping angle and minimizing the impact on wrapping quality.

[0052] In an alternative embodiment, see Figure 1 、 Figure 3 and Figure 5 In order to facilitate the adjustment of the wrapping angle of the socket 300 after the wrapping rod 120 is installed, a coaxial through hole 122 is provided in the wrapping rod 120. The axial locking mechanism 110 includes an axial locking rod 112, a first elastic member 113 and an axial handle 114. The first elastic member 113 is a compression spring. The axial locking rod 112 is slidably installed in the through hole 122. An axial locking head 111 is fixed to one end of the axial locking mechanism 110. One end of the first elastic member 113 is fixed to the axial locking head. 111, and the other end is connected to the wrapping rod 120, the axial locking rod 112 extends out of a through hole 122 at one end away from the axial locking head 111 and is installed with an axial handle 114, and the axial locking rod 112 is radially provided with a pin hole 115 at one end close to the axial handle 114. In the natural state, under the thrust of the first elastic member 113, the pin hole 115 is located in the through hole 122. When the pin hole 115 extends out of the through hole 122, the axial locking head 111 is disengaged from the locking member 600.

[0053] It should be noted that the first elastic member 113 always applies a pushing force to the locking head so that the locking head remains locked in the locking groove 610 of the locking member 600 .

[0054] When it is necessary to adjust the wrapping angle, pull the axial locking rod 112 to compress the first elastic member 113. When the pin hole 115 extends out of the through hole 122, the locking head disengages from the locking groove 610. Then, a pin or other rod-shaped object is inserted into the pin hole 115 to limit the first elastic member 113 from resetting and prevent the axial locking head 111 from being re-stuck in the locking groove 610. At this time, the hand wheel 409 can be freely rotated to drive the connector 300 and the wrapping rod 120 to rotate through the one-way reduction transmission assembly 400 to adjust the wrapping angle.

[0055] In an alternative embodiment, see Figures 1 to 5 In order to further improve the installation efficiency of the quick release mechanism 100 , the axial locking head 111 is set as a rotating body structure, and the axial locking head 111 is coaxially arranged with the wrapping rod 120 .

[0056] It should be noted that cavity 310 includes a sliding section 312 that fits within axial locking head 111. Axial locking head 111 is slidably connected to sliding section 312, and sliding section 312 has a circular cross-section. This allows for direct insertion of axial locking head 111 into sliding section 312 during installation of quick-release mechanism 100 without adjusting the installation angle.

[0057] To adjust the angle of the wrapping rod 120, the handle is pulled, which drives the locking rod to move, causing the axial locking head 111 to disengage the locking groove 610 and release the lock. The active rotating member 401 can then rotate freely. After the angle is adjusted, the handle is released, and the locking head automatically snaps into the locking groove 610 under the action of the first elastic member 113, thus fixing the angle.

[0058] In an alternative embodiment, see Figure 1 and Figure 5 In order to further improve the assembly and disassembly efficiency of the quick release mechanism 100 , a radial locking mechanism 500 is provided which further includes a second elastic member 520 , a pressure plate 530 , a fixing frame 540 and a radial handle 550 .

[0059] Among them, the fixing frame 540 is fixedly connected to the socket 300, the pressure plate 530 is fixedly installed on the radial locking rod 510, the second elastic member 520 is a compression spring, one end of the second elastic member 520 is connected to the fixing frame 540, and the other end is connected to the pressure plate 530, and the socket 300 is provided with a radial hole 320 connected to the cavity 310, the radial locking rod 510 is slidably connected to the radial hole 320, and the radial locking rod 510 can also be set to be slidably connected to the fixing frame 540.

[0060] To facilitate insertion of the wrapping rod 120 into the positioning section 311 and to facilitate insertion of the radial locking rod 510 into the radial limiting groove 121 after the wrapping rod 120 is inserted into the positioning section 311, a sloped surface 511 is provided on the end of the radial locking rod 510 that faces the cavity 310. In its natural state, the radial locking rod 510 is inserted into the cavity 310 long enough to fit into the radial limiting groove 121, and therefore inevitably contacts the wrapping rod 120. The design of the sloped surface 511 reduces resistance to insertion of the wrapping rod 120 into the positioning section 311.

[0061] The wrapping rod 120 includes a first frustum segment 123 , a second frustum segment 124 and a round rod segment 125 connected in sequence. The minimum diameter of the first frustum segment 123 is smaller than the minimum diameter of the second frustum segment 124 . The radial limiting groove 121 is provided on the second frustum segment 124 .

[0062] The first frustum section 123 and the second frustum section 124 form a multi-stage frustum structure, which facilitates the rapid alignment and insertion of the wrapping rod 120 into the positioning section 311 of the cavity 310 , thereby guiding and aligning the wrapping rod 120 .

[0063] In order to facilitate manual pulling of the radial locking rod 510 , one end of the radial locking rod 510 facing away from the cavity 310 extends out of the fixing frame 540 and is equipped with a radial handle 550 .

[0064] In this embodiment, the radial limiting groove 121 is a circular groove, and four locking grooves 610 are provided and distributed in a circumferential manner on the locking member 600 .

[0065] When the quick release mechanism 100 needs to be disassembled, the radial handle 550 is pulled outward to drive the locking rod away from the radial limiting groove 121 , so that the quick release mechanism 100 and the socket 300 can be quickly separated.

[0066] When installing the quick-release mechanism 100, during the process of inserting the wrapping rod 120 into the positioning section 311, the first frustum section 123 and the second frustum section 124 contact the inclined surface 511 of the radial locking rod 510 in sequence, pushing the radial locking rod 510 away from the center of the wrapping rod 120, and the pressure plate 530 squeezes the second elastic member 520; when the outer wall of the wrapping rod 120 is in contact with the inner wall of the positioning section 311, the wrapping rod 120 is rotated so that the radial limiting groove 121 is rotated to an angle aligned with the radial hole 320, and the second elastic member 520 pushes the radial locking rod 510 into the radial limiting groove 121, completing radial locking.

[0067] In an alternative embodiment, see Figure 1In order to facilitate the installation of the wrapping tape reel, a flange 126 is provided on the round rod segment 125; the quick-release mechanism 100 also includes a first baffle 130, a second baffle 140, a third elastic member 150, a nut 160, and a rotary handle 170. The first baffle 130, the second baffle 140, and the third elastic member 150 are all mounted on the round rod segment 125, the nut 160 is threadedly connected to the round rod segment 125, and the rotary handle 170 is fixed on the nut 160. The third elastic member 150 is a compression spring, and the two ends of the third elastic member 150 are respectively in contact with the second baffle 140 and the nut 160.

[0068] The wrapping tape roll is sleeved on the round rod segment 125 and is located between the first baffle 130 and the second baffle 140; by rotating the handle 170 to drive the nut 160 to rotate, the nut 160 moves axially along the round rod segment 125, compressing the third elastic member 150, causing the second baffle 140 to move toward the first baffle 130, and the first baffle 130 abuts against the flange 126, clamping the wrapping tape roll by elastic force.

[0069] The tensioning force can be adjusted by screwing the nut 160 into the depth to prevent the strap from slipping due to being too loose or breaking due to being too tight. The flange 126 is fixed to the end of the round rod segment 125 to prevent the first baffle 130 from axially dislodging.
