Description

Technical Field

[0001] The present invention relates to the technical field of cable tape wrapping, in particular to a four-head tape wrapping device for cable production. Background Art

[0002] In the field of cable production, the taping process plays a key role in the insulation performance, structural stability and electromagnetic shielding effect of the cable by wrapping insulating tape, shielding tape and other materials on the outer layer of the cable core. However, traditional taping devices have exposed many technical bottlenecks in actual applications, especially in the replacement of the tape reel and the connection of the tape, which seriously restricts the improvement of production efficiency and product quality. Traditional taping devices generally adopt an installation method in which the tape reel is directly fixed to the tape winding shaft of the taping machine chassis. When the tape on the tape reel is exhausted, the machine needs to be stopped to disassemble the old reel and replace it with a new one, and the rewiring and winding of the new tape must be completed manually. This process exposed the following core technical defects: First, the rigid fixed connection between the tape reel and the winding shaft requires multiple manual operations such as removing the old reel, installing the new reel, threading the tape, and rewinding it on the core in sequence when changing the tape; because the tape path involves winding operations in a narrow space, manual threading needs to adjust the position repeatedly to ensure that it is consistent with the winding position of the previous tape. A single reel change can take more than 30 minutes, resulting in frequent and long shutdowns of the production line and a drop in production efficiency of about 20%-30%; second, it is difficult to manually rewind the tape. Precisely locating the end position of the previous tape (e.g., the starting angle and axial position of the spiral wrapping) often results in axial deviations exceeding ±5mm at the junction of the new and old tapes. This can lead to excessive thickness in the overlapped area or gaps greater than 1mm, directly impacting the cable's local insulation performance and structural stability. This can even require rework of unqualified sections, increasing material waste and costs. Thirdly, with traditional fixed installation methods, when replacing the tape reel, the tape already wound on the winding shaft loses its tension support and is prone to axial retraction (up to 5-10cm). This retraction causes the tape to loosen and gaps to form between layers. Sudden changes in tension during subsequent winding can lead to tape breakage or irregular spiral pitch, necessitating further downtime. Furthermore, loose tape layers can easily allow air or moisture to penetrate, compromising the long-term reliability of the cable. Therefore, achieving rapid reel replacement, consistent tension, and precise alignment of the new and old tape without changing the tape's winding state has become a key technical bottleneck in improving the automation level of the cable taping process. Summary of the Invention

The tape wrapping is located on the detection path of the infrared sensor.

[0010] The left and right clamping plates are respectively mounted on the two screw sliders, and the rotating shaft of the lower rubber wheel is located between the left clamping plate and the right clamping plate. A screw motor is installed at one end of the locking plate, and the output shaft of the screw motor is connected to one end of the two-way threaded screw.

The wire combining block is provided with a wire combining hole, and the wire combining hole is coaxial with the hollow guide tube.

[0014] The beneficial effects of the present invention are:

[0015] 1. Place the tape reel on the outside of the tape wrapping machine chassis, and utilize the rotation characteristics of the tape on the winding and placing integrated shaft, that is, the two ends of the tape are in a wound state and the other end is in an unwound state under the rotation of the winding and placing integrated shaft. The winding and placing integrated shaft can rewind the tape on the tape reel while unwinding the wound tape and winding it around the wire core. The tape can be conveyed on the outside of the tape wrapping machine chassis to carry out the wire core taping operation. When the tape on the tape reel is conveyed, the machine is stopped, and the next tape reel is installed on the tape payout rack. The head of the tape on the tape reel is welded to the tail of the tape on the previous tape reel, and the tape reel can be quickly replaced. The tape is replaced by a continuous splicing method. There is no need to manually rewind the wire core, which avoids the repeated operations of threading the tape and the wire core in the traditional process, further shortens the tape change time and reduces material waste.

[0016] 2. The tape detection component monitors the deceleration color mark and the stop color mark at the tail of the tape through a color recognition sensor. When the deceleration color mark is detected, the system automatically reduces the wire core conveying speed and the tape winding speed to reserve buffer time for tape replacement; when the stop color mark is detected, the system stops accurately to ensure that the tail of the old tape is still wound on the tape reel, facilitating the rapid connection of the new tape head, avoiding overlap or gap problems caused by manual positioning deviation, and facilitating rapid tape connection operations.

[0017] 3. Before the tape is wound around the wire core, it is first heated by a hollow heating tube to expand the tape due to the heat. The expanded tape is then wound up through the winding-release integrated shaft and then released so that the tape can be tightly wound around the wire core. Finally, cold air is sprayed through the hollow cooling tube to cool the wire core wrapped with the tape. The principle of thermal expansion and contraction is used to shrink the tape and tightly wrap it around the wire core, thereby effectively eliminating problems such as bubbles and bulging in the tape and improving the tape wrapping effect of the wire core.

DETAILED DESCRIPTION

[0028] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings, but the protection scope of the present invention is not limited to the following.

[0029] Example 1

[0030] like Figures 1 to 9As shown, a four-head taping device for cable production includes a multi-head core rack 1, a tape unwinding rack 2 and a taping machine 3. The multi-head core rack 1 and the taping machine 3 are arranged at intervals along the conveying direction of the core. A plurality of core disks 4 are rotatably provided on the multi-head core rack 1. The core is wound on the core disk 4. The taping machine 3 includes a taping machine chassis 5 and a hollow guide tube 6. The taping machine chassis 5 is connected to the hollow guide tube 6 at one end close to the multi-head core rack 1. The core enters the taping machine chassis 5 through the hollow guide tube 6. A tape winding mechanism is provided in the taping machine chassis 5. The tape winding mechanism includes a winding and unwinding integrated shaft 7. The winding and unwinding integrated shaft 7 is hollow and coaxial with the hollow guide tube 6. The winding and unwinding integrated shaft 7 is rotatably installed on the taping machine chassis 5. A guide disk 8 is fixedly sleeved on the winding and unwinding integrated shaft 7. The wire core drum 4 is rotated to release the wire core, and the ... The wire is then fed into the cable tray 5 and the cable is fed into the cable tray 5. The cable is fed into the cable tray 5 and the cable is fed into the cable tray 5. The cable is fed into the cable tray 5 and the cable is fed into the cable tray 5. The cable is fed into the cable tray 5 and the cable is fed into the cable tray 5. The lower winding core is rotated in conjunction with the linear conveying of the wire core, so that the tape is wound on the wire core in a spiral state. The winding and unwinding integrated shaft 7 can rewind the tape on the tape reel 9 while unwinding the wound tape and winding it on the wire core. The tape can be conveyed on the outside of the tape wrapping machine case 5 to carry out the wire core wrapping operation. When the tape on the tape reel 9 is conveyed, the machine is stopped and the next tape reel 9 is installed on the tape unwinding frame 2. The head of the tape on the tape reel 9 is welded to the tail of the tape on the previous tape reel 9, and the empty tape reel 9 is removed to quickly replace the tape reel 9. The tape is replaced by a continuous connection method, and there is no need to manually rewind the wire core, which avoids the repeated operations of threading the tape and the wire core in the traditional process, further shortens the tape change time and reduces material waste.During specific implementation, a plurality of core shafts 57 are rotatably connected to the multi-head core rack 1, and each core shaft 57 is independently configured with a stepper motor for driving. A first flange 58 is fixedly sleeved on the core shaft 57, and a second flange 59 is coaxially fixed to one end of the core disc 4. The second flange 59 is connected to the first flange 58 by bolts, so that the core disc 4 can be detachably mounted on the core shaft 57, and the core disc 4 is driven to rotate by the rotation of the core shaft 57 to complete the wire-releasing operation. Similarly, when the core is conveyed, the machine is stopped to replace the fully loaded core disc 4, and the tail of the previous core is welded to the head of the next core, thereby completing the rapid splicing operation. There is no need to rearrange the core conveying line, and the uninterrupted production of the cable can be completed. The layout length of the cable is determined according to the subsequent customer needs. The wire core is clamped by the two rubber wheels to ensure that the taping position of the wire core is always in a tensioned state. When the wire core is connected, the wire core disk 4 rotates, so that the wire core disk 4 and the wire core at the clamping position are in a tensioned state, and then the wire clamping rubber wheel releases the wire core, and the machine is turned on for the taping operation.

[0031] Furthermore, a branching block 53 and a joining block 54 are fixed in sequence on the multi-head wire core rack 1 along the conveying direction of the wire core. A plurality of branching holes 55 are provided on the branching block 53, and the number of branching holes 55 is the same as the number of wire core disks 4. A joining hole 56 is provided on the joining block 54, and the joining hole 56 is coaxial with the hollow guide tube 6. The wire cores released from the plurality of wire core disks 4 are guided by the branching block 53, so that the multiple wire cores converge in the joining hole 56 of the joining block 54, and then the multiple wire cores are wired by the joining block 54 so that they pass through the hollow guide tube 6 and enter the wrapping machine chassis 5.

[0032] Example 2

[0033] Since there is a certain distance between the release position of the wrapping tape from the winding and releasing integrated shaft 7 and the winding position of the wire core, the wrapping tape will be wound on the wire core in a folded state, which may easily cause bulging due to folding and winding. Therefore, based on the embodiment 1, as shown in FIG. Figures 1 to 3As shown, a plurality of guide limit assemblies are arranged at equal intervals on the guide disk 8 along its own circumferential direction. The guide limit assemblies include two tape guide shafts 60 rotatably connected to the guide disk 8. The tape guide shafts 60 are I-shaped, and the tape passes through the I-shaped grooves of the two tape guide shafts 60. The positions of the plurality of guide limit assemblies in the horizontal direction gradually approach the tape position of the wire core, so that the position and angle of the tape are gradually adjusted by the plurality of guide limit assemblies, so that the tape will not be wound on the wire core in a folded state, thereby improving the winding effect of the tape.

[0034] Example 3

[0035] By connecting the tape outside the tape box 5, uninterrupted wire core taping operation is achieved. At this time, the conveying condition of the tape on the tape reel 9 is particularly important. It is necessary to predict the signal of the completion of the tape delivery in advance to avoid the tail of the tape being delivered into the tape box 5. For this purpose, based on the second embodiment, as shown in FIG. Figures 1 to 6 As shown, a tape detection component is provided between the tape wrapping machine 3 and the tape unwinding frame 2, and the tape wrapping detection component includes a detection frame 10 and a color recognition sensor 11 installed on the detection frame 10. The tape is sequentially coated with a deceleration color mark and a stop color mark along its tail direction. The deceleration color mark and the stop color mark are both arranged on the inner side of the tape wrapped around the wire core, and the deceleration color mark and the stop color mark are arranged at intervals. When the color recognition sensor 11 recognizes the deceleration color mark, the conveying speed of the wire core and the taping speed of the wire core are gradually reduced; when the color recognition sensor 11 recognizes the stop color mark, the wire core stops being conveyed and the wire core stops being taped, and the head of the tape on the new tape reel 9 is connected to the tail of the tape on the previous tape reel 9, and two color marks, namely the deceleration color mark, are sequentially applied to the tail of the tape. With the shutdown color mark, the color recognition sensor 11 is used to identify the color to judge the conveying condition of the tape. When the color recognition sensor 11 identifies the deceleration color mark, the conveying speed of the wire core and the conveying speed of the tape are reduced, and a buffer time is reserved for tape change to remind the staff to make preparations in advance. When the color recognition sensor 11 detects the shutdown color mark, the wire core conveying stops and the tape conveying stops. The staff rotates the tape reel 9 to make the tape fall off, and then removes the previous tape reel 9, installs the fully loaded tape reel 9 on the tape unwinding rack 2, and welds the tail of the previous tape to the head of the next tape, thereby quickly completing the docking between the tapes, avoiding overlap or gap problems caused by manual positioning deviation, and facilitating and quickly performing the tape connection operation. After the connection is completed, the machine is turned on to continue the wire core tape operation.

[0036] Example 4

[0037] Based on the third embodiment, Figures 1 to 7As shown, two groups of rotating support components are arranged at intervals along the axial direction of the tape reel 9 on the unwinding frame 2. The rotating support components include an upper lifting seat 12 and a lower lifting seat 13. The top of the upper lifting seat 12 is connected to the telescopic shaft of the upper cylinder 14, and the bottom of the lower lifting seat 13 is connected to the telescopic shaft of the lower cylinder 15. The upper cylinder 14 and the lower cylinder 15 are both vertically installed on the unwinding frame 2. The bottom surface of the upper lifting seat 12 and the top surface of the lower lifting seat 13 are both provided with semicircular grooves 16. When the upper lifting seat 12 contacts the lower lifting seat 13, the two semicircular grooves 16 form a circular groove. A main shaft is provided between the two groups of rotating support components. 17. The two ends of the main shaft 17 are respectively adapted to the circular grooves of the two sets of rotary support components. The tape disk 9 is movably mounted on the main shaft 17. The side wall of the tape disk 9 is threaded with a screw 18. The tail of the screw 18 penetrates the inner hole of the tape disk 9 and presses against the main shaft 17. Due to the large volume and heavy weight of the tape disk 9, a rotary support component is provided at both ends of the main shaft 17. The tape disk 9 is installed in the middle position of the main shaft 17 so that the main shaft 17 is evenly stressed and the service life of the main shaft 17 is extended. The rotary support component is a split structure, which is convenient for the installation and removal of the tape disk 9 and also It is convenient to replace the main shaft 17 when it is bent or damaged. The specific process is as follows: first loosen the screw 18 so that the tape disc 9 can slide on the main shaft 17, then separate one of the rotating support components, and keep the other rotating support component in the tooling state of the main shaft 17. The upper cylinder 14 drives the upper lifting seat 12 to move upward, and the lower cylinder 15 drives the lower lifting seat 13 to move downward, so that the upper lifting seat 12 is separated from the lower lifting seat 13, so that one end of the main shaft 17 forms a loading space, remove the empty tape disc 9, and then put the fully loaded tape disc 9 on the main shaft 17 through the loading space, and then The lifting seat 12 and the lower lifting seat 13 reset the support main shaft 17, and then connect the tail of the previous tape to the head of the next tape to complete the tape connection operation. Then, move the tape disk 9 on the main shaft 17 to the middle position of the main shaft 17, and finally tighten the screw 18 to complete the installation of the tape disk 9. Through the setting of two sets of rotating support components, the main shaft 17 can be rotated and installed, and the tape disk 9 can be installed and removed at the same time, which is convenient for the tape connection operation. When the main shaft 17 needs to be replaced, the two rotating support components are in a separated state at the same time, and the new main shaft 17 can be removed and installed.

[0038] Furthermore, an annular limiting groove 19 is provided at both ends of the main shaft 17, and an arc-shaped tooth 20 is fixed on the inner wall of the semicircular groove 16. The arc-shaped tooth 20 is inserted into the annular limiting groove 19 to limit the horizontal movement of the main shaft 17. An arc-shaped rubber pad 21 is fixed on the inner wall of the semicircular groove 16. The arc-shaped rubber pad 21 is pressed on the main shaft 17 by its own compression deformation. In order to avoid the winding-integrated shaft 7 from driving the wrapping disk 9 to rotate excessively through the wrapping tape, resulting in the wrapping tape being wrapped around the winding-integrated shaft 7 in a loose state, an arc-shaped rubber pad 21 is provided. The main shaft 17 is pressed by the arc-shaped rubber pad 21. There is a large friction force between 1 and the main shaft 17, and the tape needs to overcome the friction force by dragging to make the main shaft 17 rotate to release the tape, so that the tape can be kept in a tensioned state and wound on the winding-release integrated shaft 7, avoiding the problem of tape bulging on the wire core; secondly, during the process of replacing the tape reel 9, the main shaft 17 always has a rotating support component to support the main shaft 17, and the axial displacement of the main shaft 17 is limited by the cooperation of the arc-shaped teeth 20 and the annular limit groove 19, so as to avoid the main shaft 17 driving the tape reel 9 to deviate and affect the tape transportation, so that the tape transportation accuracy is higher.

[0039] Example 5

[0040] By winding the integral shaft 7 and rotating the winding tape, and then pulling the tape disc 9 to rotate and release the tape, this method is easy to cause the tape to be pulled and damaged. Therefore, based on the fourth embodiment, as shown in FIG. Figures 1 to 6 As shown, a tape-wrapping drive mechanism is provided on the tape-unwinding frame 2, one end of the main shaft 17 is connected to the tape-wrapping gear 72 through a key, and the tape-wrapping drive mechanism includes a motor mounting plate 61, a tape-wrapping drive motor 62 and a tape-wrapping cylinder 63. The motor mounting plate 61 is slidably mounted on the tape-unwinding frame 2, and the cylinder body of the tape-wrapping cylinder 63 is mounted on the tape-unwinding frame 2. The telescopic shaft of the tape-wrapping cylinder 63 is connected to the motor mounting plate 61 for driving the motor mounting plate 61 to move along the axial direction of the main shaft 17. The tape-wrapping drive motor 62 is mounted on the motor mounting plate 61, and the output shaft of the tape-wrapping drive motor 62 is connected to the tape-wrapping main gear 64, which meshes with the tape-wrapping gear 72. The motor 62 drives the main shaft 17 to rotate through the engagement of the tape wrapping main gear 64 and the tape wrapping gear 72. The main shaft 17 drives the tape wrapping reel 9 to rotate. The tape is released through the rotation of the tape wrapping reel 9, and the tape is then wound up through the winding-up integrated shaft 7. Finally, the tape is released through the winding-up integrated shaft 7 and wound on the wire core; the disassembly and assembly of the tape wrapping reel 9 is carried out at the end of the main shaft 17 away from the tape wrapping drive mechanism. When a new main shaft 17 needs to be replaced, the tape wrapping cylinder 63 drives the tape wrapping drive motor 62 to move, so that the tape wrapping main gear 64 is separated from the tape wrapping gear 72, and then the two sets of rotating support components are separated again, so that the main shaft 17 falls on the lower lifting seat 13, and the replacement of the main shaft 17 is completed.

[0041] Furthermore, a tensioning detection component is provided between the tape unwinding rack 2 and the tape wrapping chassis 5. The tensioning detection component includes a detection seat 25 and an infrared sensor 26. The detection seat 25 is provided below the tape, and the infrared sensor 26 is installed on the top of the detection seat 25. The tape is located on the detection path of the infrared sensor 26. The height of the tape is detected by the infrared sensor 26. When the tape is conveyed loosely, the detected height value will decrease. At this time, the tape driving motor 62 drives the tape disk 9 to slow down the conveying rate of the tape, so that the tape is re-tensioned and then restored to the initial speed, thereby being able to detect the conveying condition of the tape in real time, so as to adjust the conveying rate of the tape in time according to the feedback of the conveying condition.

[0043] Based on the fifth embodiment, Figures 1 to 9As shown, a hollow heating tube 22 is fixed in the tape wrapping machine chassis 5, and the hollow heating tube 22 is perpendicular to the winding-putting integrated shaft 7. A plurality of electric heating rings 23 are sleeved on the hollow heating tube 22 along its own axial direction. The tape passes through the electric heating ring 23 and is wound around the winding-putting integrated shaft 7. A temperature sensor 24 is provided between the hollow heating tube 22 and the winding-putting integrated shaft 7. The temperature sensor 24 is used to detect the temperature of the tape. The tape wrapping machine chassis 5 is connected to a cooling box 37 at one end away from the multi-head wire core rack 1. Two guide rings 38 are fixed at intervals along the conveying direction of the wire core in the cooling box 37. A cooling base is provided between the two guide rings 38. A hollow cooling tube 40 is rotatably passed through the cooling base. The hollow cooling tube 40 is coaxial with the guide ring 38. An annular cooling cavity 39 is provided in the hollow cooling tube 40. A plurality of cold air holes 41 are provided on the inner wall of the hollow cooling tube 40. The cold air holes 41 are connected to the annular cooling cavity 39. An air inlet is provided at one end of the hollow cooling tube 40. The air inlet assembly includes a cold air generator, a fixed ring 42 and an air inlet ring 43. One end of the air inlet ring 43 is coaxially fixed to the fixed ring 42, and the other end is rotatably adapted to the annular cooling cavity 39 of the hollow cooling tube 40. The fixed ring 42 is fixed on the cooling base. An annular air inlet groove 44 communicating with the annular cooling cavity 39 is opened at one end of the air inlet ring 43 close to the hollow cooling tube 40. The air inlet ring 43 is connected to the cold air generator through an air inlet duct. Before the tape is wrapped around the core, the tape is first heated by the electric heating ring 23 on the hollow heating tube 22 to expand the tape due to heat. The expanded tape is then wound up and released through the winding-release integrated shaft 7 so that the tape can be tightly wound around the core. Finally, cold air is sprayed through the hollow cooling tube 40 to cool the core around which the tape is wrapped. The principle of thermal expansion and contraction is used to shrink the tape and tightly wrap it around the core, thereby effectively eliminating problems such as bubbles and bulging in the tape and improving the tape wrapping effect of the core. To ensure that the cold air can cover the entire wrapping tape, the hollow cooling tube 40 is rotated and installed. When the wire core of the wrapping tape is transported in the hollow cooling tube 40, the cold air generated by the cold air generator enters the annular air inlet groove 44 through the air inlet duct, and then enters the annular cooling cavity 39 from the annular air inlet groove 44, and finally flows out from the cold air hole 41 to act on the wrapping tape. Through the rotation of the hollow cooling tube 40, the wrapping tape can be cooled as a whole, thereby tightening on the wire core to achieve a better wrapping effect; the fixed ring 42 is rotatably connected to the hollow cooling tube 40, so that the fixed ring 42 will not interfere with the hollow cooling tube 40. At the same time, the fixed ring 42 is fixed on the cooling base, and the fixed ring 42 does not rotate with the hollow cooling tube 40, so that the air inlet duct connected to the fixed ring 42 will not have the problem of winding around the tube.

[0044] Furthermore, a driving spindle 45 is rotatably provided in the tape wrapping chassis 5, and the two ends of the driving spindle 45 are respectively connected to a first gear 46 and a second gear 47. A third gear 48 is provided on the winding and placing integrated shaft 7, and the third gear 48 meshes with the first gear 46. A fourth gear 49 is provided on the hollow cooling tube 40, and the fourth gear 49 meshes with the second gear 47. A tape wrapping motor 50 is installed in the tape wrapping chassis 5, and the output shaft of the tape wrapping motor 50 is connected to a driving gear 51, and a driven gear 52 is provided on the driving spindle 45, and the driven gear 52 meshes with the driving gear 51. The tape wrapping motor 50 mobilizes the driving spindle 45 to rotate through the meshing of the driving gear 51 and the driven gear 52. The driving spindle 45 drives the winding and placing integrated shaft 7 to rotate through the meshing of the first gear 46 and the third gear 48, thereby realizing the tape wrapping operation. At the same time, the driving spindle 45 drives the hollow cooling tube 40 to rotate through the meshing of the second gear 47 and the fourth gear 49, thereby realizing the cooling and tightening operation of the tape.

[0045] Example 7

[0046] When the tape is being continued, the tape is in a relaxed state, so that the continuing operation can be completed. After the tape is relaxed, the tape wound on the winding-integrated shaft 7 is prone to rewinding, causing a gap between the tape and the winding-integrated shaft 7, resulting in the tape being unable to be tightly wound around the wire core during the subsequent tape wrapping process. Therefore, based on the sixth embodiment, as shown in FIG. Figures 1 to 9As shown, an anti-rotation mechanism is provided between the tensioning detection assembly and the strapping chassis 5, and the anti-rotation mechanism includes a U-shaped frame 27 and a locking assembly. An upper rubber wheel 28 and a lower rubber wheel 29 are rotatably provided in the U-shaped opening of the U-shaped frame 27, and the strap passes between the upper rubber wheel 28 and the lower rubber wheel 29. The locking assembly includes a locking plate 30, a left clamping plate 31 and a right clamping plate 32. The locking plate 30 is horizontally fixed to the U-shaped frame 27. A screw groove 33 is provided on the top surface of the locking plate 30. A bidirectional threaded screw is rotatably provided in the screw groove 33. 34. The two threaded segments of the bidirectional threaded screw 34 with opposite rotation directions are both threadedly fitted with a screw slider 35. The left clamping plate 31 and the right clamping plate 32 are respectively mounted on the two screw sliders 35. The rotating shaft of the lower rubber wheel 29 is located between the left clamping plate 31 and the right clamping plate 32. A screw motor 36 is mounted on one end of the locking plate 30. The output shaft of the screw motor 36 is connected to one end of the bidirectional threaded screw 34. During the conveying process of the strapping, the rotation of the upper rubber wheel 28 and the lower rubber wheel 29 enables the strapping to be conveyed normally. When the color recognition sensor 11 detects the stop color mark, the machine stops and the tape is continued. At this time, the screw motor 36 is started, and the screw motor 36 drives the bidirectional threaded screw 34 to rotate, so that the left clamping plate 31 and the right clamping plate 32 are moved close to the rotating shaft of the lower rubber wheel 29. The rotating shaft is clamped by the left clamping plate 31 and the right clamping plate 32, thereby limiting the rotational freedom of the lower rubber wheel 29. The friction between the lower rubber wheel 29 and the tape is locked, so that the tape between the lower rubber wheel 29 and the winding and releasing integrated shaft 7 is in tension. The tape is wound around the integral shaft 7 and the tape reel 9 and the lower rubber wheel 29 are in a tensioned state again. Finally, the machine is turned on for the tape wrapping operation. At the same time, the screw motor 36 rotates in the opposite direction to loosen the rotating shafts of the left clamping plate 31 and the right clamping plate 32, unlocking the rotational freedom of the lower rubber wheel 29 so that the tape can continue to be conveyed.

[0047] Furthermore, a clamping shaft 65 is coaxially fixed to both ends of the upper rubber wheel 28, and the clamping shaft 65 is rotatably connected to a clamping slider 66. Vertical slide grooves 67 are provided on both inner side walls of the U-shaped frame 27, and the clamping slider 66 is slidably arranged in the vertical slide grooves 67. A return spring 68 is provided in the vertical slide grooves 67, and one end of the return spring 68 is connected to the inner top wall of the vertical slide groove 67, and the other end is connected to the top of the clamping slider 66. A vertical block 69 is fixed to the top of the left splint 31 and the top of the right splint 32. A lower pressure block 70 is connected to the top of the vertical block 69, and the lower pressure block 70 and the vertical block 69 are connected in a 7 shape, wherein one clamping shaft 65 extends between the two vertical blocks 69, and a wedge surface 71 is provided at the bottom of the lower pressure block 70 near one end of the clamping shaft 65, and the clamping shaft 65 is located on the wedge surface 71 When the left clamping plate 31 and the right clamping plate 32 are reset, the lower pressing block 70 moves away from the clamping shaft 65, and the upper rubber wheel 28 is reset under the action of the reset spring 68, so that the strap can be transported between the upper rubber wheel 28 and the lower rubber wheel 29.
