Description

Technical Field

[0001] The utility model relates to the field of rubber product preparation, in particular to a steel wire crown band spiral winding and reeling device. Background Art

[0002] There are two ways to laminate the zero-degree belt layer of an all-steel radial tire: the first is to extrude a zero-degree belt layer of a width that meets the process requirements (generally 30mm~60mm) through an extruder, and roll it onto a narrow I-wheel in a single circle, and then transfer the I-wheel to the feeding device of the molding machine. During the tire molding process, the I-wheel is unwound to wrap the zero-degree belt layer around the outside of the belt layer component. This process has high working efficiency, but there is a butt joint in the zero-degree belt layer, which will affect the dynamic balance and high-speed stability of the tire. The second is to extrude a narrow width (generally 5mm~20mm) crown strip through an extruder, spirally wrap it onto a wide I-wheel, and then transfer the I-wheel to the feeding device of the molding machine. During the tire molding process, the I-wheel is unwound to spirally wrap the narrow crown strip around the outside of the belt layer component. There are many ways to choose the cross-section of the spirally wound crown strip: full circle winding, separate winding on both sides, Z-type winding, double-layer winding, etc. This process is less efficient than the first one, but the wound crown strip has no butt joints, which can improve the dynamic balance and high-speed stability of the tire, and is more in line with the current requirements for improving the high-speed performance of heavy-duty trucks.

[0003] There are three main schemes for the extrusion and winding process of steel wire crown strips: the first one is that the extruded crown strips are directly spirally wound on the wide I-shaped wheel, and there is no other material separating each superimposed layer. The advantage is that the winding structure is simple, but the disadvantage is that the rubber of the superimposed crown strips will stick after being stored for a long time, and it cannot be torn apart when it is unwound or the rubber will be torn during the tearing process to expose the steel wire. The second one is that the extruded crown strips are spirally wound on the wide I-shaped wheel, and plastic film is arranged between each superimposed layer. The plastic film adopts a single-layer superimposed disc structure. When winding, the plastic film of the two stations is switched back and forth, and finally after the rotation of multiple plastic film discs, a crown wide I-shaped wheel is fully wound. Multiple plastic film joints are artificial joints. After the I-shaped wheel is unwound by the molding machine, the plastic film spirally wound with the crown strip is treated as waste; the advantage is that the plastic film used each time is new, and the spirally wound crown strip is relatively neat; the disadvantage is that the plastic film disc and the film artificial joint need to be replaced frequently during the winding process of a wide I-shaped wheel, and the plastic film is disposable when unwound, which wastes the plastic film. The third type is that the extruded crown strip is spirally wound on a wide I-shaped wheel, and a plastic film is arranged between each superimposed layer. The plastic film adopts a structure of spiral winding on the I-shaped wheel, and the length of each plastic film I-shaped wheel winding is equal to the length of the crown strip I-shaped wheel winding. When the crown strip I-shaped wheel is unwound in the molding machine, the unwound plastic film is spirally wound back on the empty I-shaped wheel. In this way, the plastic film can be recycled many times. The advantage is that the raw materials of the plastic film are saved, and the disadvantage is that the spiral winding structure of the crown strip extrusion winding is more complicated.

[0060] It also includes a wire crown band storage device, a tension adjustment component and a tension detection component which are sequentially arranged along the traction direction of the wire crown band.

[0061] When the device of the utility model is used to spirally wind and reel the steel wire crown tape, firstly, the cloth pad I-wheel is fixed on the cloth pad guide assembly 2, and one end of the plastic film on the cloth pad I-wheel is passed through the transition guide roller assembly 3, the floating roller assembly 4, the swing frame assembly 5, and the swing arm assembly 6 in sequence, and is wound around the I-wheel of the crown tape winding and reeling assembly 8; then, one end of the steel wire crown tape on the steel wire crown tape storage device is passed through the tension adjustment assembly, the tension detection assembly, the swing frame assembly 5 and the swing arm assembly 6 in sequence, and the light wire crown tape is wound around the I-wheel of the crown tape winding and reeling assembly 8 and is located on the outer layer of the plastic film, so as to ensure that a layer of plastic film is padded between the upper and lower layers of steel wire crown tape during the winding process. At this time, the wire pulling work is completed, and then the steel wire crown tape padded with the plastic film is wound and reeled through the crown tape winding and reeling assembly 8.

[0062] As a preferred embodiment of the utility model, the cloth unwinding assembly 2 is used to unwind the plastic film spirally wound on the I-shaped wheel. The I-shaped wheel is fixed on the cloth unwinding assembly 2, and the plastic film is smoothly unwinded through the rotation and traction of the driving mechanism.

[0063] like Figure 1As shown, the cloth guiding assembly 2 includes a first left side plate 21 and a first right side plate 22 fixed on the fixed bottom plate 1, the first left side plate 21 and the first right side plate 22 are arranged opposite to each other, a first flap mechanism 23 is arranged between the first left side plate 21 and the first right side plate 22, a first clamping mechanism 24 is arranged on the first left side plate 21, and a first driving mechanism 25 is arranged on the first right side plate 22. Preferably, the distance between the first left side plate 21 and the first right side plate 22 can be greater than the length of the first flap mechanism 23, so that the fixing of I-shaped wheels of different widths can be satisfied.

[0064] like Figure 2 As shown, the first flap mechanism 23 includes a first bottom plate, first side plates 2302 are fixed to the left and right sides of the first bottom plate 2301, first lifting components 2303 are fixed to one end of the two first side plates 2302, a first hollow shaft 2304 is arranged between the other ends of the two first side plates 2302, a first mandrel 2305 is arranged in the first hollow shaft 2304, the length of the first mandrel 2305 is greater than the length of the first hollow shaft 2304, both ends of the first mandrel 2305 are fixed to the fixed bottom plate 1 through first support seats 2306, and the first lifting component 2303 drives the first side plate 2302 and the first bottom plate 2301 to move relative to the first mandrel 2305. Specifically, the two first support seats 2306 are fixed to the fixed base 1 by screws.

[0065] The first lifting component 2303 includes a universal wheel arranged on the fixed base plate 1, and the universal wheel can roll left and right on the fixed base plate 1. A first cylinder is connected to the top of the universal wheel through a first support. The two first side plates 2302 are respectively fixedly connected to the first supports on the corresponding sides. When the first cylinder is turned on, the piston rod of the first cylinder extends out and presses on the upper surface of the universal wheel, thereby driving the first side plate 2302 and the first base plate 2301 to move upward around the first core shaft 2305; when the first cylinder is closed, the piston rod of the first cylinder retracts to the starting position, thereby driving the first side plate 2302 and the first base plate 2301 to move downward around the first core shaft 2305 and return to the starting position.

[0066] The first flap mechanism 23 can realize the replacement of the I-shaped wheel. When in use, the I-shaped wheel is placed on the first base plate 2301 manually and adjusted to the position. The I-shaped wheel is driven to rise to the working position by the first cylinder, and then the I-shaped wheel in place is clamped from the left and right sides by the first clamping mechanism 24 and the first driving mechanism 25, and then the piston rod of the first cylinder is retracted to make the I-shaped wheel suspended in the air, thereby completing the fixation of the I-shaped wheel; when the I-shaped wheel needs to be removed, the first cylinder is turned on, and the piston rod is extended to drive the first base plate 2301 to move upward around the first core shaft 2305 until it rests against the I-shaped wheel, and then the I-shaped wheel is removed from the first clamping mechanism 24 and the first driving mechanism 25, and then the piston rod of the first cylinder is retracted to drive the first base plate 2301 to move downward around the first core shaft 2305, thereby removing the I-shaped wheel.

[0067] like Figure 3 As shown, the first clamping mechanism 24 is installed on the first left plate 21 and is located above the first flap mechanism 23. The first clamping mechanism 24 includes a first clamping bracket 2401. A first guide bearing seat structure 2402 facing the direction of the I-shaped wheel is arranged in the middle position of the first clamping bracket 2401. The first guide bearing seat structure 2402 includes a first bearing mounting seat fixed on the first left plate 21, a first rotating bearing is arranged on the first bearing mounting seat, and a first push rod is arranged in the first rotating bearing. Both ends of the first push rod extend out of the first rotating bearing, wherein a push shaft is arranged at one end facing the I-shaped wheel, and the other end is fixed to the first clamping bracket 2401 through a first universal ball head structure 2403. One end of the first universal ball head structure 2403 is fixed to the first clamping bracket 2401 by a screw, and the other end is connected to the first push rod through a universal ball. The first universal ball head structure 2403 can enable the first push rod to deflect by a certain angle and displacement during axial transverse movement, so that the I-shaped wheel can be fixed on the pad cloth guide component more quickly and conveniently.

[0068] The upper and lower ends of the first clamping bracket 2401 are respectively provided with first clamping cylinders 2404 facing the direction of the I-shaped wheel. One end of the first clamping cylinder 2404 is installed on the first left plate 21 by means of screws, and the other end of the cylinder piston rod is connected to the first clamping bracket 2401. Driven by the first clamping cylinder 2404, power is transmitted to the top shaft of the first guide bearing seat structure 2402 through the first clamping bracket 2401, so that the top shaft moves axially and is inserted into the hollow hole of the I-shaped wheel, thereby achieving the effect of fixing the I-shaped wheel without interfering with its rotation.

[0069] The first driving mechanism 25 includes a first motor, which is fixedly mounted on the first right side plate 22. The rotating shaft of the first motor passes through the first right side plate 22 and extends into the inner side of the first right side plate 22 to drive the I-shaped wheel to rotate to realize the wedging action of the pad.

[0070] The utility model provides a cloth guiding assembly 2, wherein the first flap mechanism 23 drives the I-wheel to rise to the position of the first clamping mechanism 24, the top shaft in the first clamping mechanism 24 is inserted into the left hollow hole of the I-wheel, and the I-wheel is driven by the first clamping cylinder 2404 to move toward the direction of the first driving mechanism 25 so that the first motor rotating shaft is inserted into the right hollow hole of the I-wheel, thereby fixing the I-wheel, and then the I-wheel is driven by the first motor to rotate to realize the guiding action of the plastic film on the I-wheel. The whole process is automated, no manual labor is required, and production efficiency is improved.

[0071] It should be noted that the structure of the crown tape winding and reeling assembly 8 in the utility model is the same as that of the pad cloth unwinding assembly 2. The difference is that the fixed I-shaped wheel in the crown tape winding and reeling assembly 8 is wider than the fixed I-shaped wheel in the pad cloth unwinding assembly 2. The structure of the crown tape winding and reeling assembly 8 will not be described in detail here.

[0072] As a preferred embodiment of the utility model, the transition guide roller assembly 3 includes a bracket 31 fixed on the upper row of the fixed base plate 1, and a first transition guide roller 32 and a second transition guide roller 33 are arranged in parallel on the top of the bracket 31. After the plastic film is guided away from the I-shaped wheel, it passes through the first transition guide roller 32 and the second transition guide roller 33 in sequence.

[0073] As a preferred embodiment of the present invention, Figure 4 As shown, the floating roller assembly 4 includes a support frame 41, the support frame 41 is fixed on the fixed bottom plate 1, a floating roller frame 42 is fixed on the upper part of the support frame 41 and located directly in front of the support frame 41, the floating roller frame 42 includes a fixed roller mounting plate 4201 fixed on the upper end of the support frame 41 and a movable roller mounting plate 4202 located below the fixed roller mounting plate 4201, and two vertically arranged linear slide rails 43 are fixed on the upper part of the support frame 41 and located below the fixed roller mounting plate 4201, and the two ends of the movable roller mounting plate 4202 slide respectively. The movable roller mounting plate 4202 is mounted on two linear guide rails 43, and a plurality of fixed pulleys 44 are mounted on the fixed roller mounting plate 4201, preferably including a first fixed pulley 4401, a second fixed pulley 4402, a third fixed pulley 4403, a fourth fixed pulley 4404, a fifth fixed pulley 4405 and a sixth fixed pulley 4406. A plurality of movable pulleys 45 are fixed on the movable roller mounting plate 4202, preferably including a first movable pulley 4501, a second movable pulley 4502 and a third movable pulley 4503, and the fixed pulleys 44 and the movable pulleys 45 are arranged staggered up and down. The movable roller mounting plate 4202 can reciprocate up and down along the linear guide rail 43, and the movable pulley 45 mounted on the movable roller mounting plate 4202 also reciprocates up and down, thereby changing the distance between the fixed pulley 44 and the movable pulley 45, which is used to adjust the guide-off rate of the plastic film.

[0074] Preferably, a laser displacement sensor (not shown in the figure) is provided behind the fixed roller mounting plate 4201, and a sensing plate (not shown in the figure) is fixed on the movable roller mounting plate, and the sensing plate is located directly below the laser displacement sensor, and can reciprocate up and down along the linear slide rail along with the movable roller mounting plate 4202. The laser displacement sensor is used to detect the distance between the fixed pulley 44 and the movable pulley 45, and maintain the storage amount of the padding cloth bypassing the fixed pulley 44 and the movable pulley 45, so that when the steel wire crown belt is wound, it is convenient to adjust the difference between the plastic film let-off speed and the crown belt winding speed, so that the film let-off speed meets the crown belt strip winding speed requirement.

[0075] As a preferred embodiment of the utility model, a disc plastic film deflecting assembly is provided on one side of the support stand 41. When the crown strip production line is not in use, the disc-shaped plastic film (the length is generally less than 1000 meters) can be fixed on the disc plastic film deflecting assembly. After the disc-shaped plastic film is deflected, the plastic film is spirally wound onto the I-shaped wheel through the crown strip winding assembly (the length is generally about 4000 meters, meeting the length requirement of a single spindle) to form a cloth pad I-shaped wheel, meeting the requirement of the spiral winding length of the crown strip I-shaped wheel.

[0076] like Figure 5 As shown, the disc plastic film deflection assembly includes a deflection shaft 46 installed on the upper side of the support frame 41. Specifically, the deflection shaft 46 is installed on the side of the support frame 41 through its own seat bearing, and a chuck 47 is provided at the front end of the core shaft of the deflection shaft 46. The chuck 47 is fixed to the core shaft of the deflection shaft 46 through a top screw and rotates with the core shaft. A pneumatic brake 48 is fixed to the tail end of the core shaft of the deflection shaft 46. The brake mounting plate of the pneumatic brake 48 is fixed to the support frame 41 through screws. When in use, the disc-shaped plastic film is loaded on the chuck 47, and the pneumatic brake 48 controls the rotation of the core shaft of the deflection shaft 46 to drive the plastic film on the chuck 47 to rotate and deflect the plastic film. During the rotation process, the pneumatic brake 48 is controlled to keep the plastic film on the chuck 47 at a constant tension when deflecting.

[0077] As a preferred embodiment of the present invention, Figure 6 As shown, the swing frame assembly 5 includes a swing frame 51, and a pad cloth guide wheel mounting plate 52 and a wire crown belt guide wheel mounting plate 53 are fixed to the upper end of the swing frame 51. Preferably, the pad cloth guide wheel mounting plate 52 and the wire crown belt guide wheel mounting plate 53 are arranged on the swing frame 51 opposite to each other, that is, the pad cloth guide wheel mounting plate 52 is arranged close to the pad cloth guide assembly 2, and the wire crown belt guide wheel mounting plate 53 is arranged away from the pad cloth guide assembly 2.

[0078] Three cloth guide wheels 54 are fixed on the cloth guide wheel mounting plate 52. The three cloth guide wheels 54 can be arranged in sequence from top to bottom or from left to right on the cloth guide wheel mounting plate 52, and their function is to drag the cloth passing through the floating roller assembly 4; a pawl 55 is also fixed on the cloth guide wheel mounting plate 52, and the function of the pawl 55 is to press the cloth against the cloth guide wheel mounting plate 52 by its own weight, ensuring that the cloth can only move in one direction from the cloth guide assembly 2 to the crown belt winding and rewinding assembly 8, to prevent the plastic film from being cut off and being pulled back by the floating roller assembly 4 when the I-shaped wheel is replaced.

[0079] Three crown band guide wheels 56 are arranged on the wire crown band guide wheel mounting plate 53 from top to bottom, which are used to support the wire crown band transmitted from the wire crown band storage device; a stop wheel 57 is also arranged on the wire crown band guide wheel mounting plate 53. The stop wheel can press the wire crown band against the wire crown band guide wheel mounting plate 53 by its own weight due to the eccentricity of its own rotating axis, ensuring that the wire crown band can only move unidirectionally from the wire crown band storage device to the crown band winding and reeling assembly 8, preventing the crown band strip from escaping from the working position when the I-shaped wheel is replaced.

[0080] As a preferred embodiment of the present invention, Figure 7 As shown, the swing arm assembly 6 includes a swing arm 61, which is composed of two oppositely arranged rectangular plates, and a crown belt transition wheel 62 and a wire-laying wheel 63 are respectively arranged at both ends of the swing arm 61, and the crown belt transition wheel 62 and the wire-laying wheel 63 are respectively connected between the two rectangular plates through a rotating shaft, and a PE transition wheel 64 is arranged on one end of the swing arm 61 close to the crown belt transition wheel 62 and located on the outside of one of the rectangular plates, and two cloth pad rollers 65 are connected to the swing arm 61 through a connecting piece, and the two cloth pad rollers 65 are respectively arranged close to the crown belt transition wheel 62 and the wire-laying wheel 63 and located below the swing arm 61.

[0081] One end of the swing arm 61 close to the crown band transition wheel 62 is hinged on the connecting block 66, and the connecting block 66 is arranged opposite to the PE transition wheel 62. In this embodiment, the PE transition wheel 64 is arranged on the swing arm 61 close to the side of the pad cloth guide-off assembly 2, and the connecting block 66 is arranged away from the side of the pad cloth guide-off assembly 2. The connecting block 66 is also fixedly connected to the lower end of the swing frame 51.

[0082] The plastic film that passes through the cloth pad guide wheel passes through the PE transition wheel 64 and the two cloth pad rollers 65 located under the swing arm 61 in turn, and is finally cushioned on the I-shaped wheel of the crown tape winding and reeling assembly 8. The steel wire crown tape that passes through the crown tape guide wheel 56 passes from the back of the crown tape transition wheel 62 to the top of the wire arrangement wheel 63 and is then wound around once. It is then wound around the crown tape winding and reeling I-shaped wheel and pressed on the outer layer of the plastic film. At this time, the wire pulling work is completed.

[0083] As a preferred embodiment of the present utility model, a cable assembly 7 is provided at the lower end of the swing frame assembly 5 and the swing arm assembly 6. Figure 8 As shown, the wire arrangement assembly 7 includes a frame 71, and the frame 71 includes a top plate and a bottom plate that are relatively arranged. The two ends of the top plate and the bottom plate are respectively connected by side plates, and the bottom plate is fixed on a support frame, and the support frame is fixed on a fixed base 1; a wire arrangement optical axis 72 is rotatably arranged between the two side plates, and the wire arrangement optical axis 72 is parallel to the axial direction of the I-shaped wheel fixed on the crown band winding and reeling assembly 8, and a wire arrangement device 73 is slidably connected to the wire arrangement optical axis 72, and two linear guide rails 74 are arranged on the upper surface of the top plate, and a slide 75 is slidably arranged on the linear guide rail 74, and the slide 75 is fixedly connected to the wire arrangement device 73, and the slide 75 is also fixedly connected to the lower end surface of the connecting block 66.

[0084] One end of the cable optical axis 72 extends out of one of the side panels and is provided with a driven wheel 76, which is connected to the driving mechanism in the crown belt winding and reeling assembly 8 through a pulley. The driven wheel 76 is driven to rotate by the driving mechanism in the crown belt winding and reeling assembly 8, so that the cable arranging device 73 can reciprocate left and right along the cable optical axis 72, and the slide 75 also reciprocates left and right along the linear guide rail 74, thereby driving the swing frame assembly 5 and the swing arm assembly 6 to reciprocate left and right. In this way, the plastic film and the steel wire crown belt are evenly wound on the winding I-shaped wheel through the reciprocating left and right movement of the swing frame assembly 5 and the swing arm assembly 6. In the utility model, the driven wheel 76 on the cable optical axis 72 is driven to rotate by the driving mechanism in the crown belt winding and reeling assembly 8, so that when the reeling work is started, the cable optical axis 72 is also driven to rotate, thereby causing the cable arranging device 73 to reciprocate left and right along the cable optical axis 72, and the two processes are carried out simultaneously to ensure that the steel wire crown belt padded with plastic film is evenly wound on the I-shaped wheel.

[0085] Preferably, a limit rod 77 is fixedly connected between the two side plates, and the limit rod 77 is located below the optical axis 72. The limit wheels 78 are respectively arranged at both ends of the limit rod 77. Specifically, the setting position of the limit rod 77 needs to ensure that the cable arranging device 73 can touch the limit wheel 78 during the left and right movement. When the cable arranging device 73 moves toward one end of the cable arranging optical axis 72 and touches the corresponding limit wheel 78, it automatically changes the movement direction and then moves toward the other end of the cable arranging optical axis 72. The plastic film and the steel wire crown belt will also be wound around the I-shaped wheel from one end to the other end, until the cable arranging device 73 touches the limit wheel 78 corresponding to the other end of the cable arranging optical axis 72 and automatically changes the movement direction. In this reciprocating operation, the steel wire crown belt padded with plastic film is evenly wound around the I-shaped wheel.

[0086] As a preferred embodiment of the present invention, during the winding process, if the tension of the crown band strip is too large, it is easy for the two overlapping crown bands on the steel wire crown band storage device to stick together, and it is easy to tear and expose the steel wire when it is unwound; during the winding process, if the tension of the crown band strip is too small, it is easy to cause misalignment, and it is easy for the two left and right crown bands spirally wound on the steel wire crown band storage device to stick together, and when it is unwound, the crown band strip cannot be arranged at the position required by the process, affecting the high-speed performance. Therefore, the present invention also includes a tension adjustment component, which is installed at the rear of the steel wire crown band storage device frame of the crown band strip extrusion production line, such as Fig. 9 As shown, the tension adjustment assembly includes a tension adjustment mounting plate 91, which is fixed to the rear of the frame of the wire crown band storage device, and three guide rollers 92, a traction roller 93 and a floating roller 94 are fixed on the front end surface of the tension adjustment mounting plate 91, wherein the three guide rollers 92 are located on the same straight line and above the traction roller 93 and the floating roller 94, and the traction roller 93, the floating roller 94 and the three guide rollers 92 are arranged in an offset manner up and down, and the floating roller 94 is slidably connected to a rodless cylinder 95 vertically fixed on the tension adjustment mounting plate 91, and a traction motor 96 is fixed on the rear end surface of the tension adjustment mounting plate 91 at a position corresponding to the traction roller 93, and the drive shaft of the traction motor 96 passes through the tension adjustment mounting plate 91 and is connected to the traction roller 93.

[0087] The traction roller 93 is driven by the driving shaft of the traction motor 95 to provide power, traction the steel crown band on the storage device, and convey the steel crown band from the storage device to the crown band winding and reeling assembly 8. The three guide rollers 92 are mainly used to hold the steel crown band and maintain a suitable wrap angle when the steel crown band is wound on the upper surface of the traction roller 93 and the floating roller 94, so as to maintain the friction between the roller and the steel crown band. The floating roller 94 is installed on the slider of the rodless cylinder 95, and follows the slider to rise and fall. The steel crown band passes around the lower surface of the floating roller 94. When the crown band strip is wound, the floating roller 94 maintains a constant tension on the steel crown band, so that the set tension can be maintained when the steel crown band is spirally wound.

[0088] As a preferred embodiment of the present invention, Fig.10 As shown, the tension detection component includes a tension detection bracket 1001, on which two guide rollers 1002 and a tension sensor 1003 are fixedly installed, wherein the tension sensor 1003 is arranged above the two guide rollers 1002, and the tension sensor 1003 and the two guide rollers 1002 are staggered up and down, and the steel wire crown belt passes around the lower surface of the first guide roller, the upper surface of the tension sensor 1003 and the lower surface of the second guide roller in sequence, and the tension sensor 1003 detects the tension value in real time.

[0089] As a preferred embodiment of the utility model, the device of the utility model also includes a controller (not shown in the figure), which is electrically connected to the tension sensor 1003 and the rodless cylinder 95 respectively, receives the tension signal generated by the tension sensor 1003, processes it to obtain the tension value of the wire crown band, and adjusts the pneumatic size of the rodless cylinder 95 according to the tension value, so that the tension of the wire crown band winding meets the process requirements and is not too large or too small to cause adverse effects.

[0090] The controller in the utility model is a commonly used PLC.

[0091] When winding and reeling the steel wire crown belt, the I-shaped wheel wrapped with the plastic film is manually fed onto the first flap mechanism 23, and is raised to the position of the first clamping mechanism 24 through the first lifting component 2303. The top shaft in the first clamping mechanism 24 is inserted into the left hollow hole of the I-shaped wheel, and the I-shaped wheel is driven by the first clamping cylinder 2404 to move toward the first driving mechanism 25 so that the first motor rotating shaft is inserted into the right hollow hole of the I-shaped wheel to fix the I-shaped wheel. Then, the I-shaped wheel is driven by the first motor to rotate to realize the deflection of the plastic film on the I-shaped wheel. In the same way, an empty I-shaped wheel is fixed on the crown belt winding and reeling assembly 8.

[0092] One end of the plastic film is sequentially passed through the first transition guide roller 32 and the second transition guide roller 33 in the transition guide roller assembly 3 and then pulled to the floating roller assembly 4, so that the plastic film sequentially passes through the upper surfaces of the sixth fixed pulley 4406 and the fifth fixed pulley 4405, the lower surface of the first fixed pulley 4501, the upper surface of the fourth fixed pulley 4404, the lower surface of the second movable pulley 4502, the upper surface of the third fixed pulley 4403, the lower surface of the third movable pulley 4501, the second fixed pulley 4402 and the upper surface of the first fixed pulley 4401, and then sequentially passes through the three cloth pad guide wheels 54 on the swing frame assembly 5 and is pulled to the swing arm assembly 6, so that it sequentially passes through the PE transition wheel 64 and the two cloth pad rollers 65, and finally pads on the I-shaped wheel on the crown belt winding and reeling assembly;

[0093] The steel wire crown belt on the crown belt storage device passes through the guide roller 92, the traction roller 93 and the floating roller 94 on the tension adjustment assembly in sequence, and then is pulled to the tension detection assembly so that it passes through the guide roller 1002 and the tension sensor 1003 in sequence, and then is pulled to the swing frame assembly 5 and passes through the three crown belt guide wheels 56 in sequence, and finally passes from behind the crown belt transition wheel 62 on the swing arm assembly to the top of the wire arrangement wheel 63 for one circle, and then is pressed on the outer layer of the plastic film on the I-shaped wheel on the crown belt winding and reeling assembly, and the wire pulling work is completed at this time;

[0094] After the wire pulling work is completed, the first driving mechanism 25 and the driving mechanism on the crown tape winding and reeling assembly 8 are turned on to carry out the crown tape winding and reeling work. During the winding process, the cycloid optical axis 72 in the wire arranging assembly 7 rotates to drive the wire arranging device 73 to move. When the wire arranging device 73 moves toward one end of the wire arranging optical axis 72 and touches the corresponding limiting wheel 78, it automatically changes the direction of movement and then moves toward the other end of the wire arranging optical axis 72. The plastic film and the steel wire crown tape will also be wound around the I-shaped wheel from one end to the other end until the wire arranging device 73 touches the other end of the wire arranging optical axis 72. The corresponding limiting wheel 78 automatically changes the movement direction, and runs back and forth in this way, winding the steel wire crown belt padded with plastic film evenly on the I-shaped wheel. During the winding and reeling process, the tension sensor 1003 in the tension detection component detects the tension signal of the crown belt in real time and sends it to the controller PLC. The PLC receives the tension signal sent by the tension sensor 1003 and processes it to obtain the tension value of the steel wire crown belt, and adjusts the pneumatic size of the rodless cylinder 95 according to the tension value, so that the tension of the steel wire crown belt winding meets the process requirements and is not too large or too small to cause adverse effects.
