[0011] The present invention has the following advantages over the prior art. It can attach the carrying strap to the bottom of the bottle body. The working process is as follows: First, the tape roll is set on the tape rack. The bottle body enters the taping machine through the conveying mechanism. The bracket can rotate following the rotating bearing seat on the fixed base. The rotating shaft connects the rotating bearing seat and the ball bearing. The ball bearing is connected to the bracket to play a role in stable support, preventing the bracket from being unstable during rotation. The cylindrical tape roll is sleeved on the bracket. During production, the tape roll can rotate with the bracket and the rotating bearing seat. The tape is released from the tape roll and contacts the idler roller to realize tape feeding. The conveying mechanism includes an inlet conveyor belt assembly for receiving the bottle body and an outlet conveyor belt assembly for transporting the product to the taping mechanism. The outlet conveyor belt assembly includes a bottom support plate and two conveyor belts. A through groove for the taping mechanism to extend out is provided between the two conveyor belts on the bottom support plate.

[0012] In the feeding mechanism, the tape first enters from the first tape-loosening mechanism, then enters the transmission mechanism and the second tape-loosening mechanism, and finally enters the taping part. Since the taping part will generate a pulling force on the tape during taping, the second tape-loosening mechanism is precisely set to buffer the tension of the tape. When taping is not required normally, the angle between the second movable tension roller group and the second fixed tension roller group is the largest, and the tape is taut between the second movable tension roller group and the second fixed tension roller group. If the taping part needs to tape, it will pull the tape. At this time, the second cylinder acts. The piston rod of the second cylinder drives the connecting rod to rotate, the connecting rod drives the rotating shaft to rotate, and the rotating shaft drives the second movable plate to move towards the second fixed tension roller group. At this time, the tape between the second tape-loosening mechanisms becomes loose. In this way, when the taping part pulls the tape, the tension of the tape will not be very large, and the tape will be pulled smoothly. After pulling the tape, the transmission mechanism starts to act. The role of the first tape-loosening mechanism is to temporarily store the tape. When the tape of the second tape-loosening mechanism is pulled out, the transmission mechanism needs to supplement the tape. The motor drives the driving roller to rotate, and the tape between the driving roller and the transfer roller will be continuously pulled to the second tape-loosening mechanism under the action of friction. At this time, the second movable cylinder drives the second movable tension roller group to reset. The action and principle of the first tape-loosening mechanism are the same as those of the second tape-loosening mechanism. The first tape-loosening mechanism is to buffer the pulling force of the transmission mechanism. The first cylinder and the second cylinder are both fixed on the fixed frame by pins, so that the direction of the piston rod can be variable during the movement process, enabling the connecting rod to rotate.

[0013] The two taping motors on the power module of the taping mechanism can drive the active synchronous pulley to rotate. The active synchronous pulley pulls the synchronous belt. Since one end of the synchronous belt is fixed, the synchronous belt will apply a pulling force to the abutting synchronous pulley. Since the abutting synchronous pulley is fixedly connected to the guiding rod and can move up and down on the guiding frame, the up and down movement of the guiding rod, that is, the cutter module, can be realized. In the initial state, the cutter module is at the highest position. When the bottle body is delivered to the cutter module from the left through the conveyor belt, the power module is triggered to act in cooperation with the photoelectric sensor. After the cutter module contacts the bottle body, the two motors rotate forward simultaneously. At this time, the transplanting frame will move downward while being pulled to the right by the synchronous belt. In this way, the transplanting frame will move to the right simultaneously with the bottle body in the left-right direction. The blade roller on the cutter module drives the tape to adhere to the bottle body. When the cutter module moves below the bottle body, the two motors stop rotating. The top of the side plate contacts the bottle body, and the blade roller and the tape do not contact the bottle body. At this time, the tape will become the lifting tape. The bottle body then moves, the cutter module extends from the bottom of the bottle body, and another blade roller drives the tape to adhere to the bottle body. At this time, the two motors rotate in reverse, driving the cutter module to return to the initial position. After the tape is attached, the cutter cuts the tape from the bottle body through the drive of the telescopic cylinder. The top of the tape suction block is provided with an arc surface that cooperates with the blade roller. The tape passes through between the arc surface and the blade roller. When taping is not required, the tape suction block fixes the tape through the suction hole. During the taping operation, the tape suction block does not work.

[0014] The pressing motor drives the driving wheel of the conveying component to rotate through the driving shaft. The rotating wheel drives the driven wheel to rotate through the belt. The lower part of the product is driven by the conveyor belt. During taping, the top of the product contacts the lower part of the belt. The belt can apply a certain force to the top of the product during movement, so that the product is stably conveyed by the conveyor belt. The belt itself can also provide a conveying force for the product during movement. In addition, the two side plates and the belt can guide the product to prevent the product from shifting.

[0015] The adjusting mechanism rotates the first bevel gear through the adjusting component. The first bevel gear drives the first lead screw to rotate. The first lead screw can drive the second lead screw, the third lead screw, and the fourth lead screw to rotate synchronously through the sprocket and the chain. Since the first adjusting plate is threadedly connected to the first lead screw and the second lead screw, and the second adjusting plate is threadedly connected to the third lead screw and the fourth lead screw, when the first to fourth lead screws rotate, the first adjusting plate and the second adjusting plate can be driven to lift synchronously. In this way, the components can be driven to move synchronously without generating a height difference, and no separate adjustment is required, saving time and being convenient to operate. Among them, the diamond bearing seat is used to fix the first to fourth lead screws, and the ball bearing is used to ensure the stability during rotation, so as to realize the height adjustment of the pressing mechanism and be applicable to products of different heights.

Fixed blocks 711 are arranged on both the first adjusting plate 79 and the second adjusting plate 710.

[0034] A taping machine of this solution can attach a lifting belt 9 to the bottom of a bottle body 8. The working process is as follows: The tape roll is first arranged on the tape rack. The bottle body 8 enters the taping machine through the conveying mechanism 2. The support 312 can rotate along with the rotating bearing seat 313 on the fixed base 311. The rotating shaft connects the rotating bearing seat 313 and the ball bearing 315. The connection between the ball bearing 315 and the support 312 plays a role in stable support, preventing the support 312 from being unstable during rotation. The cylindrical tape roll is sleeved on the support 312. During production, the tape roll can rotate along with the support 312 and the rotating bearing seat 313. The tape is released from the tape roll and contacts the idler roller 322 to achieve tape feeding. The conveying mechanism 2 includes an inlet conveyor belt assembly 21 for receiving the bottle body 8 and an outlet conveyor belt assembly 22 for transporting the product to the taping mechanism 5. The outlet conveyor belt assembly 22 includes a bottom support plate 221 and two conveyor mesh belts 222. A through slot 223 for the taping mechanism 5 to extend out is arranged between the two conveyor mesh belts 222 on the bottom support plate 221.

[0035] In the feeding mechanism, the tape first enters from the first tape-loosening mechanism 42, then enters the transmission mechanism 43 and the second tape-loosening mechanism 44, and finally enters the taping part. Since the taping part will generate a pulling force on the tape during taping, the second tape-loosening mechanism 44 is specifically set to buffer the tension of the tape. When taping is not required normally, the angle between the second movable tension roller set 416 and the second fixed tension roller set 415 is the largest, and the tape is taut between the second movable tension roller set 416 and the second fixed tension roller set 415. If the taping part needs to tape, it will pull the tape. At this time, the second cylinder 418 acts, and the piston rod of the second cylinder 418 drives the connecting rod 410 to rotate. The connecting rod 410 drives the rotating shaft 49 to rotate, and the rotating shaft 49 drives the second movable plate 417 to move towards the second fixed tension roller set 415. At this time, the tape between the second tape-loosening mechanisms 44 becomes slack. In this way, when the taping part pulls the tape, the tension of the tape will not be very large, and the tape can be pulled smoothly. After the tape is pulled, the transmission mechanism 43 starts to act. The function of the first tape-loosening mechanism 42 is to temporarily store the tape. When the tape in the second tape-loosening mechanism 44 is pulled out, the transmission mechanism 43 needs to replenish the tape. The motor drives the driving roller 413 to rotate, and the tape between the driving roller 413 and the transfer roller 414 will be continuously pulled to the second tape-loosening mechanism 44 under the action of friction. At this time, the second movable cylinder drives the second movable tension roller set 416 to reset. The action and principle of the first tape-loosening mechanism 42 are the same as those of the second tape-loosening mechanism 44. The first tape-loosening mechanism 42 is to buffer the pulling force of the transmission mechanism 43. The first cylinder 411 and the second cylinder 418 are both fixed to the fixed frame 41 by pins, which can make the direction of the piston rod variable during the movement process, enabling the connecting rod 410 to rotate.

[0036] The two taping motors 56 on the power module 51 of the taping mechanism 5 can drive the rotation of the driving synchronous pulley 57. The driving synchronous pulley 57 pulls the synchronous belt 511. Since one end of the synchronous belt 511 is fixed, the synchronous belt 511 will apply a pulling force to the abutting synchronous pulley 510. Since the abutting synchronous pulley 510 is fixedly connected to the guiding rod 512 and can move up and down on the guiding frame 59, the up and down movement of the guiding rod 512, that is, the cutter 521 module 52, can be realized. In the initial state, the cutter 521 module 52 is located at the highest position. When the bottle body 8 is delivered to the cutter 521 module 52 from the left through the conveyor belt, the power module 51 is triggered to act in cooperation with the photoelectric sensor. After the cutter 521 module 52 contacts the bottle body 8, the two motors rotate forward simultaneously. At this time, while the transplanting frame 55 is pulled to the right by the synchronous belt 511, it also moves downward. In this way, the transplanting frame 55 and the bottle body 8 move to the right simultaneously in the left-right direction. The blade roller 523 on the cutter 521 module 52 drives the tape to adhere to the bottle body 8. When the cutter 521 module 52 moves below the bottle body 8, the two motors stop rotating. The top of the side plate 514 contacts the bottle body 8, and the blade roller 523 and the tape do not contact the bottle body 8. At this time, the tape will become the lifting belt 9. The bottle body 8 then moves. The cutter 521 module 52 extends from the bottom of the bottle body 8, and another blade roller 523 drives the tape to adhere to the bottle body 8. At this time, the two motors rotate in reverse, driving the cutter 521 module 52 to return to the initial position. After the tape is attached, the cutter 521 cuts the tape from the bottle body 8 under the drive of the telescopic cylinder 520. The top of the tape suction block 524 is provided with an arc surface 527 that cooperates with the blade roller 523, and the tape passes through between the arc surface 527 and the blade roller 523. When taping is not required, the tape suction block 524 fixes the tape through the suction hole 526. During the taping operation, the tape suction block 524 does not work.

[0037] The pressing motor 63 drives the rotation of the driving wheel 67 of the conveying assembly 62 through the driving shaft. The rotating wheel drives the driven wheel 68 to rotate through the belt. The lower part of the product is driven by the conveyor belt. When taping, the top of the product contacts the lower part of the belt. During the movement of the belt, a certain force can be applied to the top of the product, so that the product is stably conveyed by the conveyor belt. The belt itself can also provide a conveying force for the product during movement, and the two side plates 514 and the belt can guide the product to prevent the product from shifting.

[0038] The adjusting mechanism 7 rotates the first bevel gear 77 through an adjusting component. The first bevel gear 77 drives the first lead screw 71 to rotate. The first lead screw can drive the second lead screw 72, the third lead screw 73, and the fourth lead screw 74 to rotate synchronously through a sprocket and a chain 78. Since the first adjusting plate 79 is threadedly connected to the first lead screw and the second lead screw 72, and the second adjusting plate 710 is threadedly connected to the third lead screw 73 and the fourth lead screw 74, when the first to fourth lead screws 74 rotate, the first adjusting plate 79 and the second adjusting plate 710 can be driven to lift synchronously. In this way, the components can be driven to move synchronously without generating a height difference, and no separate adjustment is required, saving time and being convenient to operate. Among them, the diamond-shaped bearing seat 75 is used to fix the first to fourth lead screws 74, and cooperate with the ball bearing 315 to ensure the stability during rotation, so as to realize the height adjustment of the blank holding mechanism 6 and be applicable to products of different heights.
