[0056] The embodiments of the present invention will be described below with reference to the accompanying drawings.

[0057] As Figure 1 shown, the present invention provides a tape winding mechanism 60 for use in a packaging box tape winding device 100; the packaging box tape winding device 100 is used for performing tape winding operation on the packaging box 80 to improve the tape 70 sticking efficiency and sticking quality;

[0058] The above-mentioned packaging box tape winding device 100 includes a tape winding mechanism 60, a transmission mechanism 10, a support frame 20, a longitudinal movement mechanism 30, a positioning lifting mechanism 40 and a glue pressing lifting mechanism 50; wherein, the transmission mechanism 10 includes a transmission line for transporting the packaging box 80; the support frame 20 is erected above the transmission line; the longitudinal movement mechanism 30 is arranged on the upper part of the support frame 20; the positioning lifting mechanism 40 and the glue pressing lifting mechanism 50 are respectively connected to the longitudinal movement mechanism 30; the tape winding mechanism 60 is connected to the driving end of the positioning lifting mechanism 40; the glue pressing lifting mechanism 50 is located above the tape winding mechanism 60. During use, the packaging box 80 is placed on the transmission line and transported to the lower part of the support frame 20; the positioning lifting mechanism 40 drives the tape winding mechanism 60 to descend to a preset position, the tape winding mechanism 60 is operated to extend the tape 70 and cross over from above the packaging box 80; the glue pressing lifting mechanism 50 is operated to paste the tape 70 on the packaging box 80, completing the tape winding operation on the packaging box 80.

[0059] Specifically, the above-mentioned transmission mechanism 10 includes a transmission drive, a transmission frame and a transmission line. The transmission line and the transmission drive are both arranged on the transmission frame, and the transmission line is connected to the driving end of the transmission drive, and drives the packaging box 80 to move under the drive of the transmission drive; the transmission line can adopt transmission forms such as chain transmission, guide rail transmission or roller transmission, etc., which are not limited here; as Figure 2 shown, the transmission line preferably adopts roller transmission, and a plurality of rollers are evenly spaced on the transmission frame to form a transmission roller path 11. The axle of the roller is connected to the driving end of the transmission drive, and rotates axially under the drive of the transmission drive to drive the packaging box 80 to move more smoothly on the transmission roller path 11.

[0060] In some embodiments, the above-mentioned transmission mechanism 10 includes three workstations, including a loading workstation, a tape-wrapping workstation, and an unloading workstation. The packaging box 80 is placed on the loading workstation manually or in cooperation with a manipulator, and then the transmission line drives the packaging box 80 to move to the tape-wrapping 70 workstation. At this time, the transmission line stops running, and the tape winding mechanism 60, the longitudinal movement mechanism 30, the positioning lifting mechanism 40, and the glue pressing lifting mechanism 50 cooperate to wind the tape 70 around the top and two sides of the packaging box 80. Then the transmission line runs again to transport the packaging box 80 to the unloading workstation, so as to transfer the packaging box 80 into the next process.

[0061] In some embodiments, the transmission driving member is a motor, preferably a servo motor.

[0062] In some embodiments, the transmission line is provided with a stop bar, a positioning component, and several alignment sensors for positioning and limiting the packaging box 80. The stop bar is used to position the packaging box 80 in the transmission direction, the positioning component is used to position the packaging box 80 perpendicular to the transmission direction, and the alignment sensors are used to cooperate with the stop bar and the positioning component. Specifically, the stop bar is movably arranged at a set position on the transmission rack, and this set position is designed according to the best position for the winding operation. When the packaging box 80 moves to this set position driven by the transmission line, the stop bar can prevent the package from moving forward. Preferably, the stop bar makes a blocking action in response to the alignment sensor. The positioning components are oppositely arranged on both sides of the transmission rack in the transmission direction and are provided with telescopic push rods to push the packaging box 80 to move perpendicular to the transmission direction so as to align it with the tape winding mechanism 60 and ensure the accurate position of the packaging box 80. After another alignment sensor confirms the accurate position of the packaging box 80, the tape-wrapping operation is started.

[0063] In this application, the support frame 20 is used to install the longitudinal movement mechanism 30, the positioning lifting mechanism 40, and the glue pressing lifting mechanism 50. Its specific structure can be composed of several rod-shaped, strip-shaped, or plate-shaped members, which are not limited here. Preferably, as Figure 3 shown, the support frame 20 is connected to the transmission rack and includes several cross beams, several columns, and several longitudinal beams. Among them, the columns are arranged vertically on both sides of the transmission line, the cross beams are arranged horizontally between the columns on both sides of the transmission line and are located above the transmission line. The longitudinal beams are arranged in the transmission direction between the columns, so that the support frame 20 as a whole has good rigidity and stability.

[0064] Furthermore, the above-mentioned longitudinal movement mechanism 30 can be a pneumatic guide rail or a gear-rack drive, or other driving forms, which can be selected according to actual needs and are not required here. Preferably, as Figure 3As shown, the longitudinal movement mechanism 30 is a pneumatic guide rail, which specifically includes a longitudinal driving member 31, a longitudinal guide rail 32 and a longitudinal moving member 33. The longitudinal guide rail 32 is arranged on the support frame 20 along the transmission direction of the packaging box 80. The longitudinal moving member 33 is slidably connected to the longitudinal guide rail 32 and slides along the longitudinal guide rail 32 under the drive of the longitudinal driving member 31. The purpose of this design is to wind multiple tapes 70 on the packaging box 80. In this embodiment, the longitudinal movement mechanism 30 is preset with multiple working stations. When the transmission line drives the packaging box 80 to be conveyed to the set position, the longitudinal moving member 33 is located at the first working station to perform the pasting operation of the first tape 70. Subsequently, the longitudinal driving member 31 drives the longitudinal moving member 33 to move to the next working station, so that the tape winding mechanism is aligned with another position of the packaging box 80, thereby performing the pasting operation of the next tape 70.

[0065] In a specific embodiment, to ensure that the packaging box 80 and its upper cover are firmly pasted, multiple tapes 70 need to be pasted along its length direction. When in use, the length direction of the packaging box 80 is placed along its transmission direction. The longitudinal guide rail 32 is preset with multiple working stations that match the length of the packaging box 80, so that the tape 70 can be aligned with the intended pasting part of the packaging box 80 every time the longitudinal moving member 33 moves.

[0066] Furthermore, the above-mentioned positioning and lifting mechanism 40 is arranged on the longitudinal moving member 33 and can move along the transmission direction of the packaging box 80 under the drive of the longitudinal driving member 31, so that the tape 70 is aligned with the intended pasting part of the packaging box 80. The positioning and lifting mechanism 40 includes a positioning driving member 41 and a positioning moving member. The positioning moving member is arranged at the driving end of the positioning driving member 41. The tape winding mechanism 60 is arranged on the positioning moving member and performs a lifting movement under the drive of the positioning driving member 41, so that the tape 70 descends to the set position above the packaging box 80, facilitating the pasting of the tape 70.

[0067] Specifically, the above-mentioned positioning and lifting mechanism 40 can be a pneumatic guide rail or a gear and rack drive, or other driving forms, which can be selected according to actual needs and are not required here. Preferably, as Figure 4 shown, the positioning and lifting mechanism 40 is a pneumatic guide rail drive, including a positioning driving member 41, a positioning guide rod 42 and a positioning moving member 43. The positioning driving member 41 is a cylinder, arranged on the longitudinal moving member 33, and its driving end extends downward, with the end connected to the positioning moving member 43. One end of the positioning guide rod 42 is connected to the positioning moving member 43, and the other end passes through the longitudinal moving member 33 and is arranged in the vertical direction, so that the positioning moving member 43 moves smoothly in the vertical direction under the action of the positioning driving member 41.

[0068] Further, the above-mentioned glue pressing lifting mechanism 50 is arranged on the longitudinal moving member 33 and can move along the transmission direction of the packaging box 80 under the drive of the longitudinal driving member 31, so that the glue pressing lifting mechanism 50 is aligned with the stretched tape 70 and the tape 70 is pasted on the packaging box 80; preferably, as Figure 4 shown, the longitudinal moving member 33 includes a horizontal member and a vertical member. The horizontal member is used to install and position the driving member 41 and is provided with a sliding sleeve that cooperates with the positioning guide rod 42. The other end of the sliding sleeve is connected to the back of the vertical member through a fastener, and the front of the vertical member is used to connect the glue pressing lifting mechanism 50.

[0069] Specifically, the above-mentioned glue pressing lifting mechanism 50 includes a glue pressing assembly 51 for pressing the tape 70 so that the middle part of the tape 70 in the length direction is pasted on the top of the cover plate of the packaging box 80 after being stretched.

[0070] The glue pressing assembly 51 includes a first glue pressing assembly and a second glue pressing assembly. The first glue pressing assembly includes a first glue pressing driving member 511, and the second glue pressing assembly includes a second glue pressing driving member 514 and a glue pressing plate 515. The first glue pressing driving member 511 is connected to the longitudinal moving mechanism 30, and the second glue pressing driving member 514 is connected to the driving end of the first glue pressing driving member 511 and can move to a set position under the drive of the first glue pressing driving member 511. The glue pressing plate 515 is connected to the driving end of the second glue pressing driving member 514 and can paste the tape 70 on the packaging box 80 under the drive of the second glue pressing driving member 514; in use, the first glue pressing assembly 51 and the second glue pressing assembly 51 operate successively, dividing the glue pressing operation into two steps. In the first step, the glue pressing plate 515 is lowered to contact the stretched tape 70 to prevent the tape 70 from moving after being cut; in the second step, the glue pressing plate 515 presses the tape 70 against the upper cover of the packaging box 80 to complete the firm pasting of the tape 70; the height reduced in each step is set according to the height of different packaging boxes 80, which is beneficial to ensuring the pasting quality of the tape 70.

[0071] Preferably, as Figure 5 shown, the above-mentioned first glue pressing assembly 51 includes a horizontal bracket, a first glue pressing driving member 511, a first glue pressing guide rod 512 and a glue pressing moving member 513; the horizontal bracket is connected to the front of the above-mentioned vertical member, the first glue pressing driving member 511 is arranged on the horizontal bracket, preferably using cylinder transmission, and the horizontal bracket is also provided with a sliding sleeve for the first glue pressing guide rod 512 to pass through; the first glue pressing guide rod 512 is connected to the glue pressing moving member 513, and the glue pressing moving member 513 is arranged at the driving end of the first glue pressing driving member 511; the second glue pressing driving member 514 is fixed to the glue pressing moving member 513, and the glue pressing plate 515 is connected to the driving end of the second glue pressing driving member 514.

[0072] Further, the above-mentioned glue pressing lifting mechanism 50 further includes a rolling component 52. The rolling component 52 cooperates with the glue pressing component 51 to perform glue pressing operations. When the glue pressing component 51 pastes the middle part of the tape 70 in the length direction on the upper cover of the packaging box 80, the rolling component 52 pastes the extended parts at both ends of the tape 70 on the side surface of the packaging box 80, so that the tape 70 extends from the top to the box body of the packaging box 80, realizing the firm fixation of the cover plate to the box body.

[0073] Specifically, the rolling component 52 includes a rolling transverse movement driving part 521, a rolling lifting driving part 524 and a roller 525. The rolling lifting driving part 524 is arranged at the driving end of the rolling transverse movement driving part 521 and can move along the length direction of the tape 70 under the drive of the rolling transverse movement driving part 521 to be applicable to different specifications of the packaging box 80; the roller 525 is connected to the driving end of the rolling lifting driving part 524 and is located on both sides of the glue pressing plate 515. It rolls up and down along the side surface of the packaging box 80 under the drive of the rolling lifting driving part 524. When it rolls down from top to bottom, it can paste the tape 70 on the side surface of the packaging box 80.

[0074] Preferably, as Figure 5 shown, the above-mentioned rolling component 52 further includes a transverse guide rod 522 and a transverse moving part 523. The rolling transverse movement driving part 521 adopts a cylinder and can drive the transverse moving part 523 to move along the transverse guide rod 522; in a specific embodiment, the rolling transverse movement driving part 521 and the transverse guide rod 522 are both arranged on the glue pressing moving part 513 and can be initially moved above the packaging box 80 under the drive of the first glue pressing driving part 511; at least one of the rolling lifting driving parts 524 is connected to the transverse moving part 523 and moves along the transverse guide rod 522 under the drive of the rolling transverse movement driving part 521 to adjust the distance between the two rolling lifting driving parts 524 so that the distance between the two rollers 525 matches the specification of the packaging box 80; the roller 525 is connected to the driving end of the rolling lifting driving part 524, and the axle of the roller 525 is arranged parallel to the side surface of the packaging box 80 and is located on the opposite sides of the glue pressing plate 515; in this embodiment, the tape 70 is pasted in the width direction of the packaging box 80. During use, by operating the rolling transverse movement driving part 521, the distance between the two rollers 525 is slightly smaller than the width of the packaging box 80; then operate the first glue pressing driving part 511 to make the glue pressing plate 515 and the roller 525 synchronously lower to contact the tape 70, and then operate the second glue pressing driving part 514 and the rolling lifting driving part 524 to make the glue pressing plate 515 press the tape 70 on the upper cover of the packaging box 80, and the roller 525 presses the tape 70 at the junction of the upper cover and the two side surfaces of the packaging box 80. The roller 525 continues to move downward under the drive of the rolling lifting driving part 524. During this process, the roller 525 presses tightly against the side surface of the packaging box 80 and rolls downward, so that the tape 70 is firmly pasted on the side surface of the packaging box 80.

[0075] Preferably, the above-mentioned rolling lifting drive member 524 adopts a cylinder drive.

[0076] Such as Figure 6 , Figure 7 and Figure 8 As shown, the tape winding mechanism 60 proposed in the present application includes a tape mounting base 61, a guiding mechanism 62, a tape pulling mechanism 63, a tape clamping mechanism 64, a cutting mechanism 65 and a tape folding mechanism 66: Among them, the tape mounting base 61 is used to mount the tape roll; the guiding mechanism 62 is used to transmit the tape 70 so that the tape 70 travels along a preset direction; the tape pulling mechanism 63 is used to pull out the tape 70 provided by the guiding mechanism 62 by a set length; the tape clamping mechanism 64 is arranged between the guiding mechanism 62 and the tape pulling mechanism 63 and is used to clamp the stretched tape 70; the cutting mechanism 65 is used to cut the tape 70 between the tape clamping mechanism 64 and the tape pulling mechanism 63; the tape folding mechanism 66 is arranged between the cutting mechanism 65 and the tape clamping mechanism 64 and is used to pre-fold the break part of the tape 70.

[0077] Specifically, the tape clamping mechanism 64 is arranged on the side close to the guiding mechanism 62 and is arranged opposite to the tape pulling mechanism 63. When in use, after the tape pulling mechanism 63 stretches the tape 70 to a set length, the two respectively clamp both ends of the tape 70 to facilitate the cutting operation of the cutting mechanism 65; at the same time, the cutting mechanism 65 is arranged close to the tape clamping mechanism 64 so that the cut tape 70 has enough length to meet the pasting requirements of the packaging box 80; the cut tape 70 forms a break part. To meet the continuous tape winding operation, the tape pulling mechanism 63 needs to pull the break part again to pull out the tape 70 by a preset length. The above-mentioned tape folding mechanism 66 is used to bend the break part of the tape 70 toward the side with adhesive before the tape pulling mechanism 63 pulls the break part, so that when the tape pulling mechanism 63 pulls this part, it will not contact the adhesive and can quickly separate from the tape 70 to achieve continuous automated operation.

[0078] In a specific embodiment, the tape mounting base 61 adopts a pneumatic expansion shaft, and the tape 70 is wound and clamped on the pneumatic expansion shaft and will not easily fall off;

[0079] Preferably, the tape winding mechanism 60 further includes a fixing plate which is vertically connected to the positioning moving member 43 of the positioning and lifting mechanism 40 and moves up and down under the drive of the positioning drive member 41. The tape mounting seat 61, the guiding mechanism 62, the tape pulling mechanism 63, the tape clamping mechanism 64, the cutting mechanism 65 and the tape folding mechanism 66 are all fixed on the fixing plate. Among them, the tape mounting seat 61 is movably arranged at one end of the fixing plate and can rotate axially relative to the fixing plate. The guiding mechanism 62 is arranged close to the tape mounting seat 61 to facilitate the tape 70 to extend from the tape mounting seat 61 to the guiding mechanism 62. The tape clamping mechanism 64 is arranged close to the guiding mechanism 62, and the tape pulling mechanism 63 is arranged opposite to the tape clamping mechanism 64. The tape folding mechanism 66 is arranged close to the tape clamping mechanism 64, and the cutting mechanism 65 is arranged at the other end of the tape folding mechanism 66 relative to the tape clamping mechanism 64 to facilitate the tape folding mechanism 66 to pre-fold the cut tape 70.

[0080] Further, the guiding mechanism 62 includes a guiding wheel 624, a tensioning wheel 621 and a tensioning support 622. The tensioning support 622 includes a fixed seat 6221 and a movable seat 6222. The movable seat 6222 is arranged between two fixed seats 6221 and is connected to the fixed seat 6221 through a spring 6223. The tensioning wheel 621 is arranged on the movable seat 6222 and is located between two guiding wheels 624. The guiding wheel 624 is used to guide the tape 70 released from the tape roll 70, and the tensioning wheel 621 is used to adjust the tightness of the tape 70 on the guiding wheel 624 to prevent the tape 70 from becoming loose. Under the tension force provided by the spring 6223, the tensioning wheel 621 moves between two fixed seats 6221 to automatically adapt to the pulling force transmitted by the tape 70.

[0081] In a specific embodiment, two guiding wheels 624 are provided, one tensioning wheel 621 is provided, the guiding wheels 624 and the tensioning wheel 621 are staggered in the height direction, the two guiding wheels 624 are at the same horizontal height, the tensioning wheel 621 is fixed between two tensioning wheels 621 through the tensioning support 622 and is higher than the guiding wheels 624. The smooth side of the tape 70 contacts the guiding wheels 624 and the tensioning wheel 621, extends from below the first guiding wheel 624 to the tensioning wheel 621, then bypasses above the tensioning wheel 621 and extends to the other guiding wheel 624, and finally extends to the tape clamping mechanism 64 and is clamped by the tape clamping mechanism 64. When the tape 70 is elongated under the drive of the tape pulling mechanism 63, the tape clamping mechanism 64 is in a loose state. At this time, the pulling force on the tape 70 is directly transmitted to the tensioning wheel 621. When the pulling force is large, the tensioning wheel 621 moves downward under the action of the pulling force of the tape 70. When the pulling force is small, the tensioning wheel 621 moves upward and resets under the action of the spring 6223, so that the tape 70 is always in a taut state.

[0082] Further, the tape pulling mechanism 63 includes a jaw 631, a jaw driving member 632, and a transverse movement mechanism 633; the driving end of the jaw driving member 632 is connected to the jaw 631 to make the jaws 631 approach or separate from each other; the transverse movement mechanism 633 is connected to the jaw driving member 632 to drive the jaw 631 to reciprocate.

[0083] Specifically, the jaw driving member 632 preferably uses pneumatic transmission to drive the jaws 631 to approach each other to clamp the tape 70 in the thickness direction, or to drive the jaws 631 to separate from each other to release the tape 70, facilitating the adhesion of the tape 70 to the packaging box 80.

[0084] Specifically, the transverse movement mechanism 633 can be a pneumatic guide rail or a rack and pinion drive, or other driving forms, which can be selected according to actual needs. Preferably, a rack and pinion is used. As Figure 8 shown, the transverse movement mechanism 633 includes a transverse movement guide rail 6331, a transverse movement bracket 6332, and a transverse movement driving member. The transverse movement guide rail 6331 is arranged along the length direction of the fixed plate, and racks are provided on its upper and lower surfaces. The transverse movement driving member is arranged on the transverse movement bracket 6332, and a matching gear is provided at its driving end, enabling the transverse movement bracket 6332 to reciprocate along the transverse movement guide rail 6331 under the drive of the transverse movement driving member, thereby driving the jaw 631 to move. When in use, after the jaw 631 clamps the tape 70, the tape clamping mechanism 64 releases the tape 70, and the transverse movement mechanism 633 drives the jaw 631 to move away from the tape clamping mechanism 64 to a set position, stretching the tape 70 to a set length.

[0085] Further, the tape clamping mechanism 64 includes a clamping member 642 and a tape clamping driving member 641. The clamping member 642 is connected to the driving end of the tape clamping driving member 641 and is arranged opposite to the jaw 631, and clamps or releases the tape 70 under the action of the tape clamping driving member 641.

[0086] In a specific embodiment, the tape clamping driving member 641 uses a cylinder.

[0087] In a specific embodiment, the two clamping members 642 are arranged vertically. The opposite surfaces of the clamping members 642 are provided with matching grooves and protrusions. When in use, the two clamping members 642 approach each other to clamp the two surfaces of the tape 70 in the thickness direction; preferably, the upper surface of the clamping member 642 located below is provided with a protrusion and an anti-sticking coating to prevent the tape 70 from sticking to the clamping member 642 and hindering the operation of the tape pulling mechanism 63.

[0088] Further, the tape folding mechanism 66 includes a telescopic rod 661, a rotary driving member 662, and a telescopic driving member 663; the driving end of the rotary driving member 662 is connected to the telescopic rod 661 to move the telescopic rod 661 closer to or away from each other in the thickness direction of the tape 70; the telescopic driving member 663 is connected to the rotary driving member 662 to move the telescopic rod 661 closer to or away from the tape 70 in the width direction of the tape 70.

[0089] Specifically, as Figure 7 , Figure 8 shown, the telescopic rod 661, the rotary driving member 662, and the telescopic driving member 663 are all located on one side of the stretching path of the tape 70, that is, one side in the width direction of the tape 70; there are two telescopic rods 661 and two rotary driving members 662 respectively. The two telescopic rods 661 are respectively connected to the two rotary driving members 662, and the two rotary driving members 662 are connected to the driving end of the same telescopic driving member 663; one end of the telescopic rod 661 is connected to the driving end of the rotary driving member 662, and the other end extends in the width direction of the tape 70. The two telescopic rods 661 are respectively located on both sides of the tape 70 in the thickness direction, that is, one telescopic rod 661 is located on the side close to the smooth surface of the tape 70, and the other telescopic rod 661 is located on the side close to the adhesive surface of the tape 70; the rotation axis of the rotary driving member 662 is arranged parallel to the telescopic rod 661, so that the two telescopic rods 661 can approach or move away from each other under the drive of the rotary driving member 662. When the two telescopic rods 661 approach each other, they move towards the tape 70, reducing the distance between them and the tape 70, but the distance is sufficient to allow the tape 70 to pass through between them without affecting the stretching of the tape 70; when the telescopic driving member 663 operates, it drives the telescopic rod 661 to approach or move away from the tape 70 in the width direction of the tape 70, so that the telescopic rod 661 is located on both sides of the tape 70 in the thickness direction or moves out of the width range of the tape 70.

[0090] During use, the tape folding mechanism 66 and the tape clamping mechanism 64 cooperate to bend the break part of the tape 70; specifically, as Figure 8As shown, during the process that the tape pulling mechanism 63 pulls the tape 70 to extend towards one end, the tape folding mechanism 66 is located on one side of the tape 70; after the tape 70 is stretched to a preset length, the tape folding mechanism 66 operates, so that the telescopic rods 661 are respectively located on both sides of the tape 70 in the thickness direction. In a specific embodiment, the tape 70 is stretched horizontally, and after the telescopic rods 661 are in place, they are respectively located above and below the tape 70; when the cutting mechanism 65 cuts the tape 70, the tape 70 naturally drops under the action of gravity under the block of the telescopic rod 661 located below, and its smooth surface faces the tape pulling mechanism 63; then the tape pulling mechanism 63 approaches the telescopic rod 661, and at the same time the two clamping jaws 631 approach each other. In this process, the lower clamping jaw 631 first contacts the smooth surface of the dropped part of the tape 70. The break part of the tape 70 is pushed by the lower clamping jaw 631 and moves towards the direction of the telescopic rod 661, and bends upwards at the same time. As the clamping jaws 631 approach each other, the two clamping jaws 631 respectively clamp the upper surface and the lower surface of the bent part of the tape 70, and finally the bent part of the tape 70 is bonded together and clamped by the clamping jaws 631; during this process, the tape folding mechanism 66 operates to disengage from the tape 70. Specifically, first, the two rotary driving parts 662 operate to make the two telescopic rods 661 respectively move away from the upper surface and the lower surface of the tape 70, and then the telescopic driving part 663 operates to make the telescopic rods 661 further move away from the width range of the tape 70; so as to facilitate the clamping jaws 631 to complete the bending and clamping of the tape 70.

[0091] In a specific embodiment, the length of the telescopic rod 661 is not less than the width of the tape 70.

[0092] Further, the clamping jaw 631 includes a clamping part 6311 and an outward expansion part 6312. After the two clamping parts 6311 are attached to each other, the outward expansion part 6312 forms an accommodation space that cooperates with the telescopic rod 661. When in use, while the two clamping jaws 631 push the tape 70 to bend, they approach the telescopic rod 661 and respectively cross over the telescopic rod 661 from above and below the two telescopic rods 661. At this time, the telescopic rod 661 is located in the accommodation space inside the clamping jaw 631, and then moves away from the width range of the tape 70, further ensuring the bending effect of the tape 70.

[0093] Further, the cutting mechanism 65 includes a glue cutting driving part 651 and a cutter 652. The cutter 652 is connected to the driving end of the glue cutting driving part 651 and is disposed opposite to the tape 70. In a specific embodiment, the cutter 652 is located above the tape 70 and moves up and down under the drive of the glue cutting driving part 651; when the tape pulling mechanism 63 drives the tape 70 to be stretched to a preset length, the cutter 652 moves downwards to cut the tape 70; when the clamping jaws 631 of the tape pulling mechanism 63 move towards the tape folding mechanism 66 to perform the tape folding action and clamp the tape 70, the cutter 652 moves upwards to move away from the moving range of the clamping jaws 631 to avoid hindering the clamping jaws 631.

At this time, operate the rotation driving member 662 to make the two telescopic rods 661 move away from the upper surface and the lower surface of the tape 70 respectively. Subsequently, operate the telescopic driving member 663 to make the telescopic rod 661 further move away from the width range of the tape 70. The two clamping jaws 631 approach each other until the break part of the tape 70 bends upward and adheres to other parts of the tape 70, completing the bending of the tape 70. At the same time, the clamping jaws 631 clamp the tape 70.

[0111] The tape winding mechanism provided by the present application pulls out a certain length of the tape through the tape pulling mechanism, and then cuts the tape through the cutting mechanism.
