According to different process requirements, the fitting of the reinforcement layer is divided into side fitting process and U-packing process. Among them, the side fitting process is to fit a layer of reinforcement layer on the side of the completed bead (the completed bead refers to the bead with apex rubber attached), as shown in the attached Figure 1 figure, which is a partial cross-sectional view of a tire with a reinforcement layer 100 fitted on the side of a typical completed bead 101 in the prior art; the U-packing process is to perform U-shaped fitting of the reinforcement layer at one end of the completed bead, as shown in the attached Figure 2 figure, which is a partial cross-sectional view of a tire with a U-shaped fitted reinforcement layer 100 on a typical completed bead 101 in the prior art. The existing fitting of the reinforcement layer is usually manual fitting, so there is room for improvement in aspects such as the fitting quality and efficiency of the reinforcement layer.

[0034] Hereinafter, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings.

[0035] The reinforcing layer 100 described in the present invention is usually a pure film or a rubber-coated material with steel wires or fibers, and is a strip with a certain length. The strip and the ring described in the present invention are different states of the reinforcing layer during the laminating process.

[0036] See attached Figures 3 to 18As shown in the figure, the present invention discloses a laminating device 1 for forming a ring-shaped object from a strip on a drum, which includes a base 10, a first conveying device 20 arranged on the base 10, and a cutting device 30 arranged opposite to the first conveying device 20. Preferably, the cutting device 30 is arranged above the first conveying device 20 or at the output end of the first conveying device 20. The first conveying device 20 is used to receive the continuous strip after being payed off by a pay-off device (not shown) and convey it. The cutting device 30 has a cutting element 31, and the cutting element 31 is used to cut the continuous strip into a strip 100 of a fixed length; and a second conveying device 40, which has a conveying unit 44. The first conveying device 20, the second conveying device 40, and the laminating drum 200 are arranged in sequence along the horizontal direction. The conveying unit 44 can reciprocate between the first conveying device 20 and the laminating drum 200, and is used to pick up the strip 100 after being cut to a fixed length on the first conveying device 20 and convey it to the laminating drum 200; it further includes a pressing device 50, which has a pressing mechanism 51, and the pressing mechanism 51 has a separable magnetic pressing element 511. When the magnetic pressing element 511 is separated from the pressing mechanism 51, the magnetic pressing element 511 is placed on the laminating drum 200 and rotates with the laminating drum 200, and is used to fix the leading end of the strip located between the magnetic pressing element 511 and the laminating drum 200. Cooperating with the rotation of the laminating drum 200, the strip is laminated on the laminating drum to form a ring-shaped object; after the strip forms a ring-shaped object on the laminating drum, the pressing mechanism 51 retrieves the magnetic pressing element 511 from the laminating drum to complete the lamination.

[0037] With the above configuration, when the strip is conveyed on the first conveying device 20, the cutting device 30 can automatically cut the reinforcing layer in the form of a continuous strip into strips of a fixed length and transfer them to the conveying unit 44 on the second conveying device 40; the conveying unit 44 receives the strip of a fixed length from the first conveying device 20 and conveys the leading end of the strip after being cut to a fixed length to the laminating drum 200. When subsequent operations are performed after the strip is laminated on the laminating drum 200, the conveying unit 44 moves away from the laminating drum 200 and returns to the first conveying device 20 to give the laminating drum 200 enough space for subsequent operations; after the leading end of the strip is conveyed to the laminating drum 200, the leading end of the strip is fixed to the laminating drum 200 by the separable magnetic pressing element 511. The magnetic pressing element 511 rotates with the laminating drum 200, and cooperates with the laminating drum 200 to rotate one week, so as to form a ring-shaped object with the head and tail connected on the laminating drum 200 for subsequent lamination of the ring-shaped object with the completed bead. It should be noted that there is a magnetic substance on a specific position of the laminating drum 200 that attracts the magnetic pressing element 511, so as to generate a magnetic attraction force with the magnetic pressing element 511 to fix the leading end of the strip at a specified position on the laminating drum 200.

[0038] As Figure 5 shown, in order to better achieve the fixed length of the strip, a strip detection element 60 is provided on the first conveying device 20. The strip detection element 60 is used to detect the strip and feedback the detection signal to a control system (not shown) to control the cutting element 31 to cut the strip. Specifically, the control system controls the cutting time of the cutting device 30 according to parameters such as the distance between the strip detection element 60 and the cutting position where the cutting element 31 cuts, the conveying speed and time of the first conveying device 20. By adjusting different parameter settings, the fixed-length cutting of strips with different lengths can be achieved. Preferably, the strip detection element 60 is provided at the output end of the first conveying device 20, and the strip detection element 60 is a transmissive photoelectric switch, so that the strip can be detected more accurately.

[0039] As Figures 4 to 7 shown, the cutting device 30 of the present invention is arranged on the base 10 through the support frame 11, specifically arranged at the location of the first conveying device 20 on the base 10. The cutting device 30 has a fixed frame 302. A cutting drive source 321 is provided on the fixed frame 302. A tool holder 322 is provided at the drive end of the cutting drive source 321. The cutting element 31 is detachably arranged on the tool holder 322. A cutting bottom plate 323 is also provided on the fixed frame 302. The cutting bottom plate 323 is used to support the strip during cutting. The cutting bottom plate 323 is arranged along the driving direction of the cutting drive source 321 and is located directly below the cutting element 31. The cutting drive source 321 is used to drive the cutting element 31 to cut the continuous strip conveyed to the cutting bottom plate 323 by the first conveying device 20. The first conveying device 20 has a first conveyor belt 21. The cutting bottom plate 323 is arranged above the first conveyor belt 21 and is adjacent to the first conveyor belt 21, enabling the strip to cross the cutting bottom plate 323 and then return to the first conveyor belt 21 when being conveyed on the first conveyor belt 21, without affecting the normal conveying of the first conveyor belt 21. When the continuous strip is used for the first time, it is necessary to manually pull the continuous strip to the cutting bottom plate 323 for cutting. Subsequently, the head of the continuous strip conveyed by the first conveyor belt 21 crosses the cutting bottom plate 323 to reach the designated position, and the first conveyor belt 21 stops running. The cutting drive source 321 drives the cutting element 31 to move to cut the strip placed on the cutting bottom plate 323. After that, the first conveyor belt 21 continues to run to convey the strip after fixed-length cutting to the second conveying device 40, and so on for repeated fixed-length cutting and conveying.

[0040] As Figure 6As shown, optionally, a material fixing mechanism is further provided on the cutting device 30. The material fixing mechanism is used to fix the strip for assisting cutting. The material fixing mechanism includes a pressure plate 331 and a pressure driving source 332. The pressure driving source 332 is disposed on the fixing frame 302. The pressure driving source 332 is used to drive the pressure plate 331 to move relative to the cutting bottom plate 323. When the pressure plate 331 is close to and contacts the cutting bottom plate 323, the strip is fixed by the pressure plate 331 and the cutting bottom plate 323, and the cutting of the strip can be more convenient. A U-shaped groove 3311 for the cutting element 31 to pass through is provided on the pressure plate 331. During use, the cutting element 31 moves in the U-shaped groove 3311 of the pressure plate to cut the strip fixed between the pressure plate 331 and the cutting bottom plate 323. Specifically, the driving end of the pressure driving source 332 is connected to the cutting bottom plate 323, the pressure plate 331 is fixedly disposed on the fixing frame 302, and the pressure driving source 332 drives the cutting bottom plate 323 to move upward (i.e., move in the direction close to the pressure plate 331) to drive the strip located on the cutting bottom plate 323 to move in the direction close to the pressure plate 331 so as to fix the strip. As another implementation manner, the driving end of the pressure driving source 332 is connected to the pressure plate 331, and the pressure driving source 332 is used to drive the pressure plate 331 to move downward (i.e., move in the direction close to the cutting bottom plate 323) so as to cooperate with the cutting bottom plate 323 to fix the strip located on the cutting bottom plate 323. Preferably, the cutting element 31 is a blade or a circular cutter.

[0041] Since the material of the strip is a pure rubber strip or a rubber-coated material with steel wires or fibers, the cutting speed and cutting quality are better when performing hot cutting. Therefore, a heating block 34 is provided on the cutting device 30. The heating block 34 can be fixedly disposed on the fixing frame 302 at the starting position of the cutting element 31 for cutting. The heating block 34 is made of a high thermal conductivity material. A heating element (not shown) is provided in the heating block 34 to heat the heating block 34. The cutting element 31 can be placed in the heating block 34, and the cutting element 31 is heated through heat conduction. A temperature control element (not shown) is further provided in the heating block 34 to monitor the temperature of the heating block 34 to prevent the cutting element 31 from having too high a temperature and melting the strip during the cutting of the strip.

[0042] It should be noted that during the cutting process of the strip, if the steel wire or fiber inside the strip is cut or damaged, the performance of the reinforcing layer will be affected, and the cutting element 31 is also likely to be damaged, thereby reducing the service life of the cutting element 31. Therefore, when there are steel wires or fibers inside the strip, the cutting direction of the strip needs to be parallel to the steel wires or fibers inside the strip. Since the steel wires or fibers are arranged at a certain angle inside the strip, for different tires and different reinforcing layers, the joints at the head and tail of the annular material may be vertical butt joints (i.e., the strip after sizing is rectangular), or the head and tail are inclined joints at a certain angle (i.e., the strip after sizing is a parallelogram), that is, it is required that the cutting device 30 can cut the strip at different angles relative to the strip conveying direction when cutting the strip. Therefore, the cutting device 30 further includes a rotating mechanism, and the rotating mechanism is used to drive the fixed frame 302 to rotate, thereby driving the cutting element 31 to rotate at a certain angle, so that the cutting element 31 can be arranged at an angle relative to the conveying direction of the strip in the horizontal plane, so as to realize cutting the strip at a certain angle. As Figure 5 shown, specifically, the rotating mechanism includes a rotating shaft 351 and a rotation driving source (not shown) that can drive the rotating shaft 351 to rotate. The rotating shaft 351 is connected to the fixed frame 302, and the driving end of the rotation driving source is connected to the rotating shaft 351. As another implementation manner, the rotation of the cutting element 31 can also be realized manually to reduce costs. Specifically, the rotating mechanism includes a rotating shaft 351, a brake disc 352, and a brake 353. The rotating shaft 351 is connected to the fixed frame 302, the other end of the rotating shaft 351 is fixed with the brake disc 352, and the brake 353 can lock the brake disc 352. When strips of different specifications need to be cut at different angles, the brake disc 352 is rotated manually to drive the rotating shaft 351 to rotate, thereby driving the cutting element 31 on the fixed frame 302 to rotate. When the cutting element 31 rotates to the required position, the brake disc 352 is fixed by the brake 353 to lock the rotation position, so as to realize that the cutting element 31 cuts the strip 100 at different angles.

[0043] During the actual debugging process, it is not easy to make the cutting element 31 completely avoid the steel wires or fibers inside the strip, or to make the cutting direction of the cutting element 31 parallel to the arrangement direction of the steel wires or fibers inside the strip. As Figures 6 to 8As shown in the figure, to solve the above technical problems, the tool holder 322 is swingably arranged at the driving end of the cutting driving source 321. When the cutting element 31 cuts the strip 100, the tool holder 322 can drive the cutting element 31 to swing, so that the cutting element 31 is parallel to the steel wire or fiber in the strip 100. A connecting block 3211 is arranged at the driving end of the cutting driving source 321, and the tool holder 322 is swingably arranged on the connecting block 3211 through a fastening structure 36. Specifically, the fastening structure 36 is a combination of a pin shaft 361 and a sliding bearing 362. The end 3221 of the tool holder 322 connected to the connecting block 3211 is U-shaped. The sliding bearing 362 is arranged on the connecting block 3211, and the pin shaft 361 is fixed on the U-shaped end 3221 of the tool holder 322. The free end of the pin shaft 361 away from the tool holder 322 passes through the sliding bearing 362 and is arranged in the connecting block 3211. There is a clearance fit between the pin shaft 361 and the sliding bearing 362, that is, the pin shaft 361 and the sliding bearing 362 can rotate relative to each other, so that the tool holder 322 can make a small swing relative to the connecting block 3211, that is, relative to the cutting driving source 321. When the cutting element 31 cuts the strip and encounters the steel wire or fiber in the strip, the cutting element 31 is subjected to resistance and will drive the tool holder 322 to swing by a certain small angle in the direction of the resistance, so as to adjust the direction of the cutting element 31 arranged on the tool holder 322, so that the cutting element 31 avoids the steel wire or fiber in the strip, thereby avoiding cutting the steel wire or fiber in the strip.

[0044] As Figures 6 to 8 shown in the figure, since the tool holder 322 is swingably arranged at the driving end of the cutting driving source 321, in order to reset the tool holder 322, that is, each cutting starts from the same angle and the same position, the cutting device 30 is also provided with a reset mechanism 37. The reset mechanism 37 includes a limit block 371 arranged on the fixed frame 302 and a positioning shaft 372 arranged on the tool holder 322. The limit block 371 is arranged at the cutting starting position. The limit block 371 has a U-shaped opening 3711. The starting end 3712 of the U-shaped opening 3711 is arranged in a shape of an inverted V for guiding the positioning shaft 372. The positioning shaft 372 is perpendicular to the U-shaped opening of the limit block. There is a small clearance fit between the width W of the U-shaped opening and the length L of the positioning shaft 372, that is, the width W of the U-shaped opening is slightly larger than the length L of the positioning shaft 372. When the cutting element 31 returns to the cutting starting position after each cutting, the positioning shaft 372 on the tool holder 322 enters the U-shaped opening 3711 of the limit block through the guiding of the starting end 3712 of the inverted V-shaped opening on the limit block. The position of the positioning shaft 372 is adjusted through the U-shaped opening 3711 of the limit block, so as to drive the tool holder 322 to swing by an angle and return to the initial position for reset.

[0045] AsFigures 10 to 13 As shown, the second conveying device 40 of the present invention includes an angle adjustment frame 41. The angle adjustment frame 41 is arranged on the base 10. A forward and backward driving source 42 is fixedly arranged on the angle adjustment frame 41. The driving end of the forward and backward driving source 42 is connected to a forward and backward frame 43. The conveying unit 44 is arranged on the forward and backward frame 43. The forward and backward driving source 42 is used to drive the forward and backward frame 43 to move back and forth on the angle adjustment frame 41, so as to drive the conveying unit 44 to move back and forth between the first conveyor belt 21 and the laminating drum 200, pick up the fixed-length strip after being cut by the cutting device 30 on the first conveyor belt 21 and convey the strip to the laminating drum 200 for lamination; after the lamination is completed, the conveying unit 44 returns to the first conveying device 20 to give enough space at the laminating drum 200 for subsequent operations of laminating the strip on the completed bead.

[0046] As Figure 3 and 4 As shown, the pressing device 50 of the present invention is arranged on the second conveying device 40 through a connecting frame 12, specifically above the end of the second conveying device 40 close to the laminating drum 200 and fixedly connected to the forward and backward frame 43. The pressing device 50 can move forward and backward with the forward and backward frame 43 to approach or move away from the laminating drum 200 in the horizontal direction.

[0047] As Figure 14 and 16As shown in the figure, the blanking device 50 of the present invention includes a support bracket 52, and the blanking mechanism 51 is arranged on the support bracket 52. The blanking mechanism 51 includes a telescopic driving source 512, the driving end of the telescopic driving source 512 is connected to the opening and closing driving source 513, the driving end of the opening and closing driving source 513 is connected to the opening and closing main member 514, and the opening and closing main member 514 is detachably connected to the magnetic blanking element 511. The opening and closing driving source 513 is used to drive the opening and closing main member 514 to open and close to clamp or release the magnetic blanking element 511, and the telescopic driving source 512 is used to drive the opening and closing driving source 513 to move up and down, so as to drive the magnetic blanking element 511 to be placed on the surface of the laminating drum 200 or separated from the surface of the laminating drum 200, thereby clamping or releasing the magnetic blanking element 511. During use, when the telescopic driving source 512 drives the magnetic blanking element 511 to move down to the surface of the laminating drum 200 to fix the head of the strip on the surface of the laminating drum 200, the opening and closing driving source 513 drives the opening and closing main member 514 to open to release the magnetic blanking element 511, so that the magnetic blanking element 511 can be placed on the laminating drum 200 and rotate with the laminating drum 200 to assist the laminating drum 200 in laminating the strip; when the strip forms a ring on the surface of the laminating drum 200, the opening and closing driving source 513 drives the opening and closing main member 514 to close to clamp the magnetic blanking element 511, and then the telescopic driving source 512 drives the magnetic blanking element 511 to move up so that the magnetic blanking element 511 is separated from the surface of the laminating drum 200, thereby completing the lamination of the strip, so that the ring on the laminating drum 200 can perform subsequent operations.

[0048] As Figure 17 shown, specifically, the opening and closing main member 514 is a set of clamping blocks (5141 and 5142), the opening and closing driving source 513 is a separable clamping jaw cylinder, the clamping blocks 5141 and 5142 are respectively fixed on the two clamping jaws of the clamping jaw cylinder 513, and a locking block 5111 is arranged at one end of the magnetic blanking element 511 far from the contact with the laminating drum 200. When the clamping jaw cylinder 513 opens and closes, it drives the clamping blocks 5141 and 5142 to separate or approach to release or clamp the locking block 5111, thereby realizing the release or clamping of the magnetic blanking element 511. Further, locking pins 515 are arranged on the clamping blocks 5141 and 5142, and shaft holes 5112 are arranged on the locking block 5111. The locking pins 515 can cooperate with the shaft holes 5112 on the locking block 5111. When the clamping jaw cylinder 513 drives the clamping blocks 5141 and 5142 to approach each other to clamp the locking block 5111, the locking pins 515 are inserted into the shaft holes 5112 to position the magnetic blanking element 511, so that the position of the magnetic blanking element 511 on the blanking mechanism 51 remains unchanged each time, thus ensuring the unchanged position during blanking.

[0049] It should be noted that there are requirements for the position where the strip is attached to the completed bead, and the accuracy of this position is determined by the accuracy of the position where the strip is attached to the surface of the building drum 200. In actual use, since the conveying unit 44 on the second conveying device 40 cannot be completely close to the building drum 200, that is, when the strip is conveyed from the output end of the conveying unit 44 to the building drum 200, the leading end of the strip is in a free state. In this state, the position where the strip is conveyed to the building drum 200 may deviate from the predetermined position. As Figure 14 and 15 shown, in order to solve the above technical problems, optionally, the material pressing device 50 of the present invention further includes a feeding mechanism 53. The feeding mechanism 53 is used to pick up the leading end or trailing end of the strip located at the output end of the conveying unit 44, and transfer the leading end or trailing end of the strip to the building drum 200 to ensure the accurate position when the strip is conveyed to the building drum 200. Specifically, the feeding mechanism 53 includes a feeding support 531. A picking driving source 532 is fixedly arranged on the feeding support 531. The picking driving source 532 is arranged in a direction perpendicular to the conveying direction of the strip. The driving end of the picking driving source 532 is detachably connected to a picking element 533 through a connecting member 535. It further includes a feeding driving source 534. The feeding driving source 534 is fixedly arranged on the support bracket 52. The feeding driving source 534 is arranged along the conveying direction of the strip. The driving end of the feeding driving source 534 is fixed to the feeding support 531. The picking driving source 532 is used to drive the picking element 533 to move downwards close to the strip for picking. The feeding driving source 534 drives the feeding support 531 to move along the conveying direction of the strip, so as to drive the picking element 533 arranged on the feeding support 531 to move the leading end or trailing end of the strip to the building drum 200 to complete the feeding. Preferably, the picking element 533 is a vacuum suction cup or a needle punching suction cup.

[0050] As Figure 3 and Figure 4 shown, the building device of the present invention further includes a centering mechanism 70. The centering mechanism 70 is arranged at the input end of the first conveying device 20. The centering mechanism 70 is used to perform position centering adjustment on the strip entering the input end of the first conveying device 20 to ensure the accuracy of the input position of the strip.

[0051] Since the strip after length determination is relatively long, with a length between 1.2 meters and 2.5 meters, it is prone to deviation during the conveying process. As Figure 11 and Figure 12As shown in the figure, in order to maintain the positional accuracy of the strip during the process of transporting the strip from the transport unit 44 to the laminating drum 200, a guiding mechanism 71 is provided on the second transport device 40. The guiding mechanism 71 is arranged at the output end of the transport unit 44 and is used to guide the strip passing through the output end of the transport unit 44. Specifically, the guiding mechanism 71 includes two relatively arranged positioning driving sources 711. The driving end of the positioning driving source 711 is connected to a positioning block 712. The positioning driving source 711 is used to drive the positioning block 712 to expand and contract along the width direction of the strip, so as to limit the strip within the width space defined by the two positioning blocks 712 to achieve guiding. During use, when the positioning driving source 711 drives the positioning block 712 to contract, that is, when the distance between the two positioning blocks 712 reaches the maximum, the transport unit 44 transports the head of the strip to the output end of the transport unit 44. At this time, the strip is between the two positioning blocks 712 (at this time, the distance between the positioning blocks is greater than the width of the strip). By driving the positioning block 712 to extend through the positioning driving source 711, the strip is pushed to move in the width direction, so as to limit the strip between the two positioning blocks 712 to achieve head guiding (at this time, the distance between the positioning blocks 712 is approximately equal to the width of the strip). The strip moves through the position defined by the guiding mechanism 71 during the transportation process.

[0052] As Figure 13 and Figure 14 shown in the figure, further, the laminating device 1 of the present invention is further provided with a deviation correction unit for performing real-time position correction on the strip. The deviation correction unit includes a deviation correction element 541 arranged at the output end of the transport unit 44. The deviation correction element 541 is used to detect the position of the strip, and further includes a moving driving source 542. The moving driving source 542 is arranged on the second transport device 40. Specifically, the moving driving source 542 is fixedly arranged on the advancing and retreating frame 43 along the width direction of the strip. The driving end of the moving driving source 542 is connected to the transport unit 44 and is used to drive the transport unit 44 to move on the advancing and retreating frame 43 along the width direction of the strip. The transport unit 44 and the advancing and retreating frame 43 are movably connected through a guiding component 543. Preferably, the guiding component 543 is a combination of a guide rail and a slider. The deviation correction element 541 is a deviation correction lens or a vision detection camera. The deviation correction element 541 is arranged on a support bracket 52 directly above the output end of the transport unit 44. During use, the deviation correction element 541 detects the position of the strip directly below it, cooperates with the control system to compare with the preset position, and the moving driving source 542 drives the transport unit 44 to move along the width direction of the strip according to the comparison result of the control system, so as to adjust the position of the strip in its width direction during transportation to achieve real-time deviation correction, and the moving amount is adjusted according to the comparison result.

[0053] As Figure 14As shown, optionally, a pressure roller mechanism 55 is further provided on the blank holder device 50. The pressure roller mechanism 55 includes a downward pressing drive source 551 which is fixedly arranged on the support bracket 52. The drive end of the downward pressing drive source 551 is directly or indirectly connected to the rotatable pressure roller 552. During the process of the strip being attached to the attachment drum 200, the downward pressing drive source 551 is used to drive the pressure roller 552 to press down on the strip on the surface of the attachment drum 200, and cooperate with the rotation of the attachment drum 200 to better press the strip onto the attachment drum 200. And when the strip is connected end to end on the attachment drum, the pressure roller is used to roll-press the joint between the head and the tail of the strip, so that the joint is flatter and better combined, thereby improving the attachment quality. When the drive end of the downward pressing drive source 551 is indirectly connected to the pressure roller 552, the blank holder device 50 further includes a downward pressing rotating shaft 553 and a rotating frame 554. The downward pressing rotating shaft 553 is rotatably arranged on the support bracket 52. The downward pressing rotating shaft 553 is fixedly arranged with the rotating frame 554. The pressure roller 552 is detachably arranged on the rotating frame 554. The drive end of the downward pressing drive source 551 is fixed to the downward pressing rotating shaft 553 through a rotating arm 555. The downward pressing drive source 551 is used to drive the downward pressing rotating shaft 553 to rotate, thereby driving the rotating frame 554 to rotate on the support bracket 52, and further driving the pressure roller 552 arranged on the rotating frame 554 to rotate. By indirectly connecting the downward pressing drive source 551 to the pressure roller 552 as described above, it is more suitable for pressing the strip on attachment drums of different sizes.

[0054] It should be noted that when the strip of the present invention is attached to the attachment drum, it needs to be attached to the attachment drum 200 in a tangential state to achieve better attachment quality. For different tires, the sizes of the attachment drums 200 used are different, that is, it is required that the conveying unit 44 can be adjusted in height so that the strip can be tangent to the attachment drum 200 when it is attached to the attachment drum 200. As Figure 9 As shown, in order to realize the height adjustment of the conveying unit 44, the angle adjustment frame 41 is rotatably arranged on the base 10 through a rotating member 411. One end of the angle adjustment frame 41 far from the rotatable arrangement with the base 10 is connected to the base 10 by arranging a lifting mechanism 412. The lifting mechanism 412 drives the angle adjustment frame 41 to rotate around the base 10. Specifically, the rotating member 411 is a combination of a rotating shaft and a bearing, and the lifting mechanism 412 is a screw jack.

[0055] The strip of the present invention is relatively soft and is prone to deformation and stretching. When the first conveying device 20 and the second conveying device 40 are used to convey the strip by separate drive sources respectively, the problem of inconsistent conveying speeds is likely to occur. And if the conveying speeds of the first conveying device 20 and the second conveying device 40 do not match, it is easy to cause pulling or stacking of the strip. As Figure 18As shown in the figure, in order to make the conveying speeds of the first conveying device 20 and the second conveying device 40 for the strip consistent, the present invention realizes the driving of the first conveying device 20 and the second conveying device 40 by the same driving source by providing a clutch driving mechanism 80. A synchronous driving source 201 is provided on the second conveying device 40, and the synchronous driving source 201 is connected to the conveying unit 44 for driving the conveying unit 44 to convey. The clutch driving mechanism 80 includes a first engaging member 81 connected to the conveying unit 44, an engaging shaft 82 connected to the first conveying device 20, a second engaging member 83 is provided at one end of the engaging shaft 82 far from the connection with the first conveying device 20, and further includes a clutch driving source 84. The driving end of the clutch driving source 84 is connected to the second engaging member 83 through a sliding component 85. The clutch driving source 84 drives the sliding component 85 to move on the engaging shaft 82, thereby driving the second engaging member 83 to engage or separate from the first engaging member 81. When the second engaging member 83 engages with the first engaging member 81, the synchronous driving source 201 is used to drive the first conveying device 20 and the conveying unit 44 to convey the strip at the same time, so as to convey the strip onto the conveying unit 44; when the second engaging member 83 separates from the first engaging member 81, the synchronous driving source 201 only drives the conveying unit 44 to convey the strip, so as to convey the strip to the position of the laminating drum 200.

[0056] Specifically, the first conveying device 20 of the present invention includes a first transmission mechanism 22. One end of the first transmission mechanism 22 is connected to a first belt pulley 24 through a first belt pulley shaft 23, and the first conveyor belt 21 is arranged on the first belt pulley 24; the conveying unit 44 of the second conveying device 40 has a second transmission mechanism 402. One end of the second transmission mechanism 402 is connected to the driving end of the synchronous driving source 201, and the other end of the second transmission mechanism 402 is connected to a second belt pulley 404 through a second belt pulley shaft 403, and the second conveyor belt 401 is arranged on the second belt pulley 404; the first engaging member 81 is arranged at one end of the second belt pulley shaft 403, the engaging shaft 82 is arranged at one end of the first transmission mechanism 22 far from the first belt pulley shaft 23, and the second engaging member 83 is movably arranged at one end of the engaging shaft 82 far from the first transmission mechanism 22; the sliding component 85 has a connecting end 851 and a working end 852. The connecting end 851 of the sliding component is connected to the driving end of the clutch driving source 84, and the working end 852 of the sliding component 85 is movably arranged on the engaging shaft 82. The first engaging member 81 and the second engaging member 83 are tooth-shaped structures that can mesh with each other. Preferably, the first transmission mechanism 22 is a combination of a multi-stage synchronous belt and a synchronous belt pulley, and the second transmission mechanism 402 is a combination of a synchronous belt and a synchronous belt pulley.

[0057] The present invention also discloses a laminating method for sizing a strip and laminating it onto a drum to form an annular object, which includes the following steps: a) Driving the first conveyor belt 21 on the first conveying device 20 to rotate to convey a continuous strip, so that the strip passes over the cutting position and reaches the detection position; b) After the strip detection element 60 detects and identifies the strip, the control system controls the first conveyor belt 21 on the first conveying device 20 to stop rotating according to the parameter setting, so that the strip reaches the specified position to achieve sizing; c) The cutting drive source 321 drives the cutting element 31 to cut the strip; d) Driving the first conveyor belt 21 on the first conveying device 20 and the second conveyor belt 401 on the conveying unit 44 to rotate to convey the sized strip to the specified position of the conveying unit 44, which can be achieved by controlling the conveying time or by setting a detection switch, and this specified position is usually at the output end of the conveying unit 44; e) The advancing and retracting drive source 42 drives the advancing and retracting frame 43 to move along the strip conveying direction on the angle adjustment frame 41, driving the conveying unit 44 to move between the first conveying device 20 and the laminating drum 200, and conveying the strip to the laminating drum 200; f) The pressing mechanism 51 drives the magnetic pressing element 511 to be placed on the surface of the laminating drum 200, and releases the magnetic pressing element 511 to fix the head of the strip on the laminating drum 200; g) The laminating drum 200 rotates to laminate the strip onto the laminating drum 200; h) During the conveying and laminating of the strip, the deviation rectifying unit performs real-time deviation rectification on the strip to ensure the position accuracy of the strip laminated on the laminating drum 200; i) The pressing mechanism 51 retrieves the magnetic pressing element 511 to complete the lamination.

[0058] After step e), the following steps are further included: The feeding mechanism 53 takes the head of the strip at the specified position of the conveying unit 44, and moves the strip to the specified position on the laminating drum 200 for head feeding.

[0059] Before step i), the following steps are further included: After the laminating drum 200 rotates a certain angle, the feeding mechanism 53 takes the tail of the strip at the specified position of the conveying unit 44, and moves the tail of the strip to the specified position on the laminating drum 200 for tail feeding to form an annular object.

[0060] After the head feeding, the following steps are further included: The guiding mechanism 71 guides the strip, so that the strip is conveyed within the area defined by the guiding mechanism 71.

[0061] After step g), the following steps are further included: The pressing roller mechanism 55 drives the pressing roller 552 to press down onto the laminating drum 200. As the laminating drum 200 rotates, it drives the strip to be laminated on the surface of the laminating drum 200, and the pressing roller 552 performs roller pressing on the strip, so that the strip is laminated better on the surface of the laminating drum 200.

[0062] After step i), the following steps are further included: after the strip is wound around the laminating drum 200 for one circle, the pressure roller 552 rolls the joint of the head and tail of the strip to make the joint of the head and tail of the strip closer.
