Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of correction tape production, in particular to an outer winding type correction tape assembling method. BACKGROUND

[0002] The current correction tape includes a lower shell, an upper shell, a tape nozzle, a tape releasing wheel, a tape core, a tape collecting wheel and a nozzle shell. The assembling steps of the correction tape are as follows: (1) the tape releasing wheel is installed on the tape releasing guide shaft of the lower shell, the tape collecting wheel is installed on the tape collecting guide shaft of the lower shell, and the tape nozzle is installed in the tape nozzle installation slot of the lower shell, so that the tape releasing wheel and the tape collecting wheel can rotate around the corresponding guide shafts, and the tape releasing wheel and the tape collecting wheel are engaged; (2) the tape core is placed on the tape releasing wheel, and the core hole of the tape core is sleeved on the wheel hole of the tape releasing wheel, so that the tape core is drivingly connected with the tape releasing wheel; (3) the tape core releases the tape from the tape releasing wheel, the mechanical hand drives the clamp to clamp the tape core head, the tape core head is wound around the corresponding tape body guide shaft on the lower shell, then is wound around the tape nozzle, is wound around the corresponding tape body guide shaft again, and finally is attached to the tape collecting wheel, and the tape core head is wound more than half a turn on the tape collecting wheel, so as to ensure that the tape core head can be firmly attached to the tape collecting wheel; the loose tape body is tensioned by rotating the tape collecting wheel; (4) the upper shell is buckled with the lower shell, and the nozzle shell is sleeved on the tape nozzle, and thus the assembling of the entire correction tape is completed.

[0003] However, the above-mentioned tape core needs to be temporarily attached to the tape body guide shaft for pre-positioning when the tape is attached, and then the clamp of the mechanical hand clamps the tape core head, so that the tape core head is sequentially wound around the tape body guide shaft, the tape nozzle and the tape body guide shaft, and finally the tape core head is attached to the tape collecting wheel. Since the size of the current correction tape is getting smaller and smaller, the distance between the tape releasing wheel and the tape collecting wheel is relatively narrow, the clamp of the mechanical hand cannot pass through the gap between the tape releasing wheel and the tape collecting wheel, and the tape core head is difficult to be attached to the tape collecting wheel, so that the tape attaching and assembling process is relatively complicated and inconvenient, and the assembling efficiency is relatively low. SUMMARY

[0004] The present application solves the problem of providing an outer winding type correction tape assembling method, which can complete the tape attaching operation outside the lower shell and then perform subsequent assembling, so that the correction tape assembling is more free.

[0005] In order to solve the above technical problems, the technical scheme adopted by the present application is as follows:

[0006] An outer winding type correction tape assembling method, characterized by comprising the following steps:

[0007] (1) installing the tape releasing wheel, the tape core and the tape nozzle of the correction tape to the corresponding positions in the lower shell of the correction tape, and setting the tape collecting wheel of the correction tape outside the lower shell of the correction tape;

[0008] (2) Clamp and pull the core head of the correction tape at the unwinding wheel and attach it to the take-up wheel, and before or after the core head is attached, pull the core around the belt mouth;

[0009] (3) Drive the take-up wheel to rotate, so that the belt core is pre-wound several times on the take-up wheel, and then clamp the take-up wheel and fit it onto the take-up guide shaft of the lower shell; or clamp the take-up wheel and fit it onto the take-up guide shaft of the lower shell, and then drive the take-up wheel to rotate, so that the belt core is pre-wound several times on the take-up wheel.

[0010] In the preferred embodiment, in step (1), the core head of the correction tape is temporarily attached to the tape body guide shaft in the lower shell. This arrangement allows the core head to be pre-positioned, allowing the core head to be separated from the tape core in advance, making it easier to clamp the core head later.

[0011] In the preferred embodiment, in the step (1), at least one base is provided, and a positioning groove for fixing the lower shell of the correction tape is provided on the base according to the specifications of the lower shell of the correction tape. The base is also provided with a positioning mechanism for positioning the take-up wheel, and the positioning mechanism is located outside the positioning groove, and the take-up wheel is mounted on the positioning mechanism.

[0012] In a specific solution, in step (1), a notch is provided on the edge of the positioning groove so that the correction tape nozzle can pass through, and the positioning mechanism is located in front of the notch; in step (2), the correction tape core is clamped and pulled around the nozzle at the unwinding pulley, and then the correction tape core head is attached to the take-up pulley. When placing the correction tape, the nozzle is passed through the notch and exposed outside the positioning groove, making it easier for the core to pass around the nozzle. When the positioning mechanism is located in front of the notch, when the core is pulled toward the take-up pulley on the positioning mechanism, the core head can first pass around one side of the nozzle before being attached, and then the core head is attached to the take-up pulley.

[0013] In another specific solution, in step (1), a notch is provided on the edge of the positioning groove for the correction tape nozzle to pass through, and the positioning mechanism is located close to the side where the notch is located; in step (2), the core head of the correction tape is directly attached to the take-up pulley. In this specific solution, the core head is attached and then the tape core is pulled around the nozzle.

[0014] In a further preferred embodiment, in step (1), the positioning mechanism is a positioning post. In addition to the positioning post, the positioning mechanism may also adopt other structures capable of fixing the take-up pulley, such as a positioning block capable of being extended in the take-up pulley hole or a clamping block capable of clamping the lower edge of the take-up pulley.

[0015] In a further preferred embodiment, in the step (2), the tape core head is clamped and pulled by the tape sticking mechanism at the tape releasing wheel and attached to the tape winding wheel; in the step (3), the tape winding wheel is driven to rotate by the tape winding mechanism to pre-wind the tape, and then the tape winding wheel is clamped by the clamping mechanism at the positioning mechanism and fitted to the tape winding guide shaft of the lower shell, or the tape winding wheel is clamped by the clamping mechanism at the positioning mechanism and fitted to the tape winding guide shaft of the lower shell, and then the tape winding wheel is driven to rotate by the tape winding mechanism to pre-wind the tape. In the step (3), the tape winding wheel on the tape winding guide shaft is driven to rotate by the tape winding mechanism, so that the tape core is pre-wound on the tape winding wheel for several turns, thereby ensuring the firm connection between the tape winding wheel and the tape core.

[0016] In a further preferred embodiment, one side of the base is provided with a tape pressing mechanism for fixing the tape releasing wheel. The tape pressing mechanism is pressed against the upper end surface of the tape releasing wheel, thereby maintaining the balance of the tape releasing wheel during tape releasing and avoiding the displacement of the tape releasing wheel during tape sticking, tape winding and clamping.

[0017] In a further preferred embodiment, the tape pressing mechanism comprises a tape pressing lifting mechanism and a tape pressing head, and the power output end of the tape pressing lifting mechanism is upwardly arranged, and the tape pressing head is installed on the power output end of the tape pressing lifting mechanism. Generally, the tape pressing lifting mechanism comprises a tape pressing cylinder seat and a tape pressing lifting cylinder, the tape pressing lifting cylinder is installed on the tape pressing cylinder seat, the piston rod of the tape pressing lifting cylinder is upwardly arranged, and the tape pressing head is installed on the end of the piston rod of the tape pressing lifting cylinder. By driving the piston rod of the tape pressing lifting cylinder to shrink downwardly, the tape pressing head is driven to descend downwardly, so that the tape pressing head is pressed against the upper end surface of the tape releasing wheel.

[0018] In a further preferred embodiment, the tape pressing head comprises a tape pressing seat and a pressing block, the tape pressing seat is installed on the power output end of the tape pressing lifting mechanism, the pressing block is installed on the tape pressing seat, and a recess capable of accommodating the upper end surface of the tape releasing wheel is formed on the lower end surface of the pressing block. When the tape releasing wheel is releasing the tape, the tape releasing wheel can smoothly rotate in the recess of the pressing block, thereby avoiding the rotation of the tape releasing wheel being hindered by the lower end surface of the pressing block.

[0019] In a further preferred embodiment, the tape pressing mechanism further comprises a tape nozzle pressing block for fixing the tape nozzle of the correction tape. When the tape pressing head is pressed against the upper end surface of the tape releasing wheel, the tape nozzle pressing block is also pressed against the tape nozzle of the correction tape, thereby maintaining the balance of the tape nozzle and the two sides of the tape releasing wheel. In one specific embodiment, the tape nozzle pressing block is installed on the tape pressing seat. When the tape pressing seat is driven to descend downwardly by the tape pressing lifting mechanism, the pressing block and the tape nozzle pressing block can simultaneously descend, the pressing block fixes the tape releasing wheel of the correction tape, and the tape nozzle pressing block fixes the tape nozzle of the correction tape.

[0020] In a further preferred solution, the side surface of the nozzle pressing block is a slope surface which gradually inclines downward from outside to inside. When the nozzle pressing block is pressed on the nozzle, the side surface of the nozzle pressing block is aligned with the nozzle, increasing the guiding area of the nozzle. When the take-up wheel descends in the vicinity of the nozzle, the core can gradually insert into the gap between the inner wall of the lower shell and the nozzle from outside to inside under the guidance of the slope surface.

[0021] In a specific solution, the step (1) further comprises a rack, and the base is arranged on the rack. The rack is sequentially provided with a taping station and a wheel clamping station from front to back. The rack is provided with a moving mechanism capable of driving the base to switch positions between the taping station and the wheel clamping station. The taping mechanism corresponds to the taping station, the wheel clamping mechanism corresponds to the wheel clamping station, and the winding mechanism corresponds to the taping station or the wheel clamping station.

[0022] In another specific solution, the step (1) further comprises a rack, and the base is arranged on the rack. The rack is sequentially provided with a taping station, a winding station and a wheel clamping station from front to back. The rack is provided with a moving mechanism capable of driving the base to switch positions between the taping station and the winding station, and between the winding station and the wheel clamping station. The taping mechanism corresponds to the taping station, the winding mechanism corresponds to the winding station, and the wheel clamping mechanism corresponds to the wheel clamping station.

[0023] Generally, the moving mechanism comprises a horizontal driving motor, a driving pulley, a synchronous pulley, a synchronous belt and a translation seat. The horizontal driving motor is installed on the rack. The driving pulley and the synchronous pulley are rotatably installed on the rack. The synchronous belt is tensioned outside the driving pulley and the synchronous pulley. The translation seat is connected with the synchronous belt. The driving pulley is in transmission connection with the power output shaft of the horizontal driving motor. The base is installed on the translation seat. The horizontal driving motor drives the driving pulley to rotate, thereby driving the synchronous pulley and the synchronous belt to transmit and realize the horizontal movement of the translation seat and the base thereon. Of course, the moving mechanism can also adopt other structures to realize the translation of the base on different stations, for example, the moving mechanism can adopt a stepping motor, a spiral bevel gear, a ball screw, a sliding block, a guide rail, a translation seat and the like to realize translation. The stepping motor realizes movement by controlling the stepping angle. The spiral bevel gear can convert the rotary motion of the motor into linear motion. The translation seat is driven to move by the ball screw.

[0024] In a further preferred embodiment, the tape mechanism includes a tape bracket, a first swing arm, a second swing arm, a tape lifting mechanism, a first clamp and a first rotation driving mechanism capable of driving the first swing arm to rotate, and a second rotation driving mechanism capable of driving the second swing arm to rotate; the first rotation driving mechanism is installed on the tape bracket, the fixed end of the first swing arm is installed on the power output end of the first rotation driving mechanism, the second rotation driving mechanism is installed on the movable end of the first swing arm, the fixed end of the second swing arm is installed on the power output end of the second rotation driving mechanism, the tape lifting mechanism is installed on the movable end of the second swing arm, the first clamp is installed on the power output end of the tape lifting mechanism, and the first clamp is located between the correction tape belt guide shaft and the positioning mechanism; driven by the first rotation driving mechanism, the correction tape belt guide shaft is in the movement path of the first clamp; and driven by the second rotation driving mechanism, the movement path of the movable end of the second swing arm is greater than the distance between the correction tape belt guide shaft and the farthest point of the outer diameter of the take-up wheel. Then, the first swing arm is driven by the first rotating drive mechanism to continue to swing along the taking-up direction of the take-up wheel, so that the core head of the correction tape can be partially wrapped around the take-up wheel, ensuring that the core head can be more tightly fitted on the take-up wheel.

[0025] Typically, the first and second rotary drive mechanisms are both rotary cylinders. The tape lifting mechanism is a lifting cylinder. The first fixture includes two clamping jaws and a tape clamping drive mechanism for driving the two clamping jaws to open and close. The tape clamping drive mechanism is a pneumatic finger, with the fixed ends of the two clamping jaws mounted on the two pneumatic fingers, and the clamping ends of the two clamping jaws correspondingly engaged.

[0026] Of course, the above-mentioned taping mechanism can be implemented by a multi-axis manipulator or a simple two-axis manipulator in conjunction with some auxiliary structures; the auxiliary structure can be a push rod that pushes the tape core head toward the take-up reel so that the tape core head is tightly attached to the take-up reel; the above-mentioned auxiliary structure can also be a structure that drives the take-up reel to rotate so that the tape core head wraps around the take-up reel several times. The above-mentioned taping mechanism can also be implemented by other specific structures.

[0027] In a further preferred embodiment, the clamping wheel mechanism includes a manipulator and a second clamp, the second clamp being mounted on a power output end of the manipulator and being located above between the correction tape take-up guide shaft and the positioning mechanism. Typically, the manipulator can be a two-axis manipulator, a three-axis manipulator, or a multi-axis manipulator.

When the belt winding lifting mechanism drives the belt winding pressure seat to descend downward, the belt winding pressure block descends to press the take-up wheel on the positioning mechanism as the belt winding pressure seat descends, and then the belt winding pressure block is driven to rotate by the belt winding drive mechanism. Under the pressing action, the take-up wheel rotates along with the belt winding pressure block, so that the belt core is pre-wound several times on the take-up wheel.

[0029] Compared with the prior art, the present invention has the following advantages:

[0030] This external winding correction tape assembly method sets the taping operation of the tape core on the outside of the lower shell, which increases the space for taping and enables the tape core head to be quickly attached to the take-up wheel. Taping is simple and convenient, avoiding tearing or even breaking of the tape core head. It can also be achieved by completing the pre-winding operation outside the lower shell and then assembling the clamping wheel, or by assembling the clamping wheel before performing the pre-winding operation, making the correction tape assembly more flexible.

[0038] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] Example 1

[0040] like Figure 1-5 As shown, the outer-wrap correction tape assembly method in this embodiment includes the following steps:

[0041] (1) Install the correction tape unwinding wheel 73, the tape core 74, and the tape nozzle 76 to the corresponding positions in the correction tape lower shell 71, and set the correction tape take-up wheel 72 outside the correction tape lower shell 71;

[0042] (2) Clamp and pull the core head 741 of the correction tape at the unwinding pulley 73 and attach it to the take-up pulley 72, and pull the core 74 around the tape mouth 76 before the core head 741 attaches;

[0043] (3) Drive the take-up reel 72 to rotate, so that the tape core 74 is pre-wound around the take-up reel 72 for several turns, and then clamp the take-up reel 72 and fit it onto the take-up guide shaft 75 of the lower shell 71.

[0044] In step (1), the tape core head 741 of the correction tape is temporarily attached to the tape body guide shaft 77 in the lower shell 71. Through this arrangement, the tape core head 741 can be pre-positioned, so that the tape core head 741 is pre-detached from the tape core 74, which is convenient for subsequent clamping of the tape core head 741.

[0045] In step (1), a plurality of bases 2 are provided. According to the specifications of the correction tape lower shell 71, a positioning groove 21 for fixing the correction tape lower shell 71 is provided on the base 2. A positioning mechanism 22 for positioning the take-up pulley 72 is also provided on the base 2. The positioning mechanism 22 is located outside the positioning groove 21, and the take-up pulley 72 is mounted on the positioning mechanism 22.

[0046] In step (1), the positioning mechanism 22 is a positioning column.

[0047] In step (1), a notch 211 is provided on the edge of the positioning groove 21 for the correction tape nozzle 76 to pass through, and the positioning mechanism 22 is located in front of the notch 211; in step (2), the core 74 of the correction tape is clamped and pulled around the nozzle 76 at the unwinding wheel 73, and then the core head 741 of the correction tape is attached to the take-up wheel 72. When placing the correction tape, the nozzle 76 is passed through the notch 211 and exposed outside the positioning groove 21, making it easier for the core 74 to pass around the nozzle 76. When the positioning mechanism 22 is in front of the notch 211, when the core 74 is pulled toward the take-up wheel 72 on the positioning mechanism 22, the core 74 can first pass around one side of the nozzle 76 before the core head 741 is attached, and then the core head 741 is attached to the take-up wheel 72.

[0048] In step (2), the tape core head 741 is clamped and pulled at the unwinding wheel 73 by the tape attaching mechanism 3 to the take-up wheel 72; in step (3), the take-up wheel 72 is driven to rotate by the tape winding mechanism 4 to perform pre-winding, and then the take-up wheel 72 is clamped at the positioning mechanism 22 by the clamping wheel mechanism 5 and mounted on the take-up guide shaft 75 of the lower housing 71. In step (3), the take-up wheel 72 on the take-up guide shaft 75 is driven to rotate by the tape winding mechanism 4, so that the tape core 74 is pre-wound several times on the take-up wheel 72, thereby ensuring a firm connection between the take-up wheel 72 and the tape core 74.

[0049] In step (1), a frame 1 is further provided, the base 2 is provided on the frame 1, and a taping station 11, a tape winding station 12 and a clamping wheel station 13 are provided on the frame 1 in sequence from front to back. A moving mechanism 14 is provided on the frame 1 that can drive the base 2 to switch positions between the taping station 11 and the tape winding station 12, and between the tape winding station 12 and the clamping wheel station 13. The taping mechanism 3 corresponds to the taping station 11, the tape winding mechanism 4 corresponds to the tape winding station 12, and the clamping wheel mechanism 5 corresponds to the clamping wheel station 13.

[0050] A tape pressing mechanism 6 is provided on one side of the base 2 for fixing the correction tape pay-out wheel 73. The tape pressing mechanism 6 presses on the upper end surface of the pay-out wheel 73 to maintain the balance of the pay-out wheel 73 during the tape pay-out and prevent the position of the pay-out wheel 73 from shifting when the take-up wheel 72 is applying the tape, winding the tape, and clamping the tape.

[0051] The tape pressing mechanism 6 includes a tape pressing lifting mechanism 61 and a tape pressing head 62. The power output end of the tape pressing lifting mechanism 61 is arranged upward, and the tape pressing head 62 is mounted on the power output end of the tape pressing lifting mechanism 61. Generally, the tape pressing lifting mechanism 61 includes a tape pressing cylinder base 611 and a tape pressing lifting cylinder 612. The tape pressing lifting cylinder 612 is mounted on the tape pressing cylinder base 611, and the piston rod of the tape pressing lifting cylinder 612 is arranged upward. The tape pressing head 62 is mounted on the end of the piston rod of the tape pressing lifting cylinder 612. By driving the piston rod of the tape pressing lifting cylinder 612 to retract downward, the tape pressing head 62 is driven downward, so that the tape pressing head 62 is pressed against the upper end surface of the unwinding pulley 73.

[0052] The tape pressing head 62 includes a tape pressing seat 621 and a pressure block 622. The tape pressing seat 621 is mounted on the power output end of the tape pressing lifting mechanism 61, and the pressure block 622 is mounted on the tape pressing seat 621. The lower end surface of the pressure block 622 is provided with a recessed portion capable of accommodating the upper end surface of the correction tape unwinding wheel 73. When unwinding the tape, the unwinding wheel 73 can rotate smoothly in the recessed portion of the pressure block 622, preventing the lower end surface of the pressure block 622 from obstructing the rotation of the unwinding wheel 73.

[0053] The tape pressing mechanism 6 also includes a nozzle pressing block 63 for fixing the correction tape nozzle 76. When the tape pressing head 62 is pressed on the upper end surface of the unwinding pulley 73, the nozzle pressing block 63 is also pressed on the correction tape nozzle 76, which can maintain the balance between the nozzle 76 and the unwinding pulley 73. In a specific embodiment, the nozzle pressing block 63 is installed on the tape pressing seat 621. The nozzle pressing block 63 is also installed on the tape pressing seat 621. When the tape pressing lifting mechanism 61 drives the tape pressing seat 621 to descend, the pressing block 622 and the nozzle pressing block 63 can descend at the same time, the pressing block 622 fixes the correction tape unwinding pulley 73, and the nozzle pressing block 63 fixes the correction tape nozzle 76.

[0054] The side of the nozzle pressure block 63 is formed with a slope 631 that gradually slopes downward from the outside to the inside. When the nozzle pressure block 63 presses against the nozzle 76, the side of the nozzle pressure block 63 aligns with the nozzle 76, increasing the guiding area of ​​the nozzle 76. When the take-up reel 72 descends near the nozzle 76, the tape core 74, guided by the slope 631, can be gradually inserted downward from the outside to the inside into the gap between the inner wall of the lower housing 71 and the nozzle 76.

[0055] The taping mechanism 3 includes a taping bracket 31, a first swing arm 32, a second swing arm 33, a taping lifting mechanism 34, a first clamp 35, and a first rotation driving mechanism 36 capable of driving the first swing arm 32 to rotate, and a second rotation driving mechanism 37 capable of driving the second swing arm 33 to rotate; the first rotation driving mechanism 36 is installed on the taping bracket 31, the fixed end of the first swing arm 32 is installed on the power output end of the first rotation driving mechanism 36, the second rotation driving mechanism 37 is installed on the movable end of the first swing arm 32, and the fixed end of the second swing arm 33 is installed on the power output end of the second rotation driving mechanism 37 At the power output end, the tape lifting mechanism 34 is installed on the movable end of the second swing arm 33, and the first clamp 35 is installed on the power output end of the tape lifting mechanism 34, and the first clamp 35 is located between the correction tape belt guide shaft 77 and the positioning mechanism 22; driven by the first rotation drive mechanism 36, the correction tape belt guide shaft 77 is located on the movement path of the first clamp 35; and driven by the second rotation drive mechanism 37, the movement path of the movable end of the second swing arm 33 is greater than the distance between the correction tape belt guide shaft 77 and the farthest point of the outer diameter of the take-up wheel 72. During operation, the first swing arm 32 is driven to swing by the first rotary drive mechanism 36, driving the first clamp 35 on the second swing arm 33 to move to the top of the correction tape guide shaft 77; then, the first clamp 35 is driven to descend by the tape lifting mechanism 34, so that the first clamp 35 clamps the tape core head 741 adhered to the correction tape guide shaft 77; then, the first clamp 35 is driven to rise upward by the tape lifting mechanism 34, driving the tape core head 741 to pass over the upper edge of the lower shell 71, so that the tape core head 741 and the tape guide shaft are aligned. The shaft 77 disengages; the second swing arm 33 is then driven by the second rotary drive mechanism 37 to swing in the direction of the positioning mechanism 22, so that the first clamp 35 pulls the core head 741 to unwind the tape until the core head 741 passes over the outer side of the take-up pulley 72 on the positioning mechanism 22; the first swing arm 32 is then driven by the first rotary drive mechanism 36 to continue to swing along the take-up direction of the take-up pulley 72, so that the core head 741 of the correction tape can be partially wrapped around the take-up pulley 72, ensuring that the core head 741 can fit more tightly on the take-up pulley 72.

[0056] Typically, the first and second rotary drive mechanisms 36, 37 are both rotary cylinders. The tape lifting mechanism 34 is a lifting cylinder. The first clamp 35 includes two clamping jaws and a tape clamping drive mechanism for driving the two clamping jaws to open and close. The tape clamping drive mechanism is a pneumatic finger, with the fixed ends of the two clamping jaws mounted on the two pneumatic fingers, and the clamping ends of the two clamping jaws correspondingly engaged.

[0057] The clamping wheel mechanism 5 includes a manipulator 51 and a second clamp 52. The second clamp 52 is mounted on the power output end of the manipulator 51 and positioned above the correction tape take-up guide shaft 75 and the positioning mechanism 22. Typically, the manipulator 51 can be a two-axis manipulator 51, a three-axis manipulator 51, or a multi-axis manipulator 51. Of course, the manipulator 51 can also adopt a structure similar to the taping mechanism 3.

[0058] The belt winding mechanism 4 includes a belt winding lifting mechanism 41, a belt winding pressure seat 42, a belt winding pressure block 43 and a belt winding drive mechanism 44 capable of driving the belt winding pressure block 43 to rotate. The power output end of the belt winding lifting mechanism 41 is set upward, the belt winding pressure seat 42 is installed on the power output end of the belt winding lifting mechanism 41, the belt winding drive mechanism 44 is installed on the belt winding pressure seat 42, and the belt winding pressure block 43 is installed on the power output end of the belt winding drive mechanism 44 and is directly above the positioning mechanism 22. When the belt winding lifting mechanism 41 drives the belt winding pressure seat 42 to descend downward, the belt winding pressure block 43 descends to press the belt take-up wheel 72 on the positioning mechanism 22 as the belt winding pressure seat 42 descends, and then the belt winding pressure block 43 is driven to rotate by the belt winding drive mechanism 44. Under the pressing action, the belt take-up wheel 72 rotates along with the belt winding pressure block 43, so that the belt core 74 is pre-wound on the belt take-up wheel 72 for several turns.

[0059] Typically, the tape winding and lifting mechanism 41 comprises a tape winding cylinder base 411 and a tape winding and lifting cylinder 412. The tape winding and lifting cylinder 412 is mounted on the tape winding and lifting cylinder base 411, with the piston rod of the tape winding and lifting cylinder 412 facing upward. The tape winding and pressing seat 42 is mounted on the end of the piston rod of the tape winding and lifting cylinder 412. By driving the piston rod of the tape winding and lifting cylinder 412 downward to retract, the tape winding and pressing seat 42 and the tape winding and pressing block 43 thereon are driven downward, so that the tape winding and pressing block 43 can press the take-up pulley 72 on the positioning mechanism 22.

[0060] The belt winding drive mechanism 44 includes a drive motor 441, a driving pulley 442, a driven pulley 443, and a synchronous belt 444. The drive motor 441 is mounted on the belt winding pressure seat 42. The driving pulley 442 and the driven pulley 443 are both rotatably mounted on the belt winding pressure seat 42. The synchronous belt 444 is tensioned outside the driving pulley 442 and the driven pulley 443. The belt winding pressure block 43 is coaxially connected to the driven pulley 443. The driving pulley 442 is in transmission connection with the power output shaft of the drive motor 441.
