[0003] The existing bottle body will be cleaned with a spray head before labeling, and water stains are easily left on the outside of the bottle body, which will cause water vapor on the inner wall after the label sleeve is heat-shrunk.

The tilt after heat shrinkage makes the product unqualified, and the existing conveyor belt is prone to tilting forward and backward when conveying the bottle body, causing a large number of bottles at the rear to be blocked, so that the assembly line is blocked and the production process is time-consuming and labor-intensive.

[0031] In this embodiment, the bottle fixing mechanism 4 includes two groups of first gears 41, and the two groups of first gears 41 are symmetrically arranged on both sides of the first conveyor belt 2 at the upper end of the first bracket 1. Two groups of first motors 411 are installed at the lower end of the first bracket 1. The output shafts of the two groups of first motors 411 are respectively fixedly connected to the first gears 41 close to the rear of the two groups of first gears 41. The two groups of first gears 41 are respectively rotatably connected with two groups of symmetrical chains 42, and the outer sides of the two groups of chains 42 are fixedly connected with multiple groups of latch teeth 43.

[0035] In this embodiment, one of the two groups of first gears 41 has its upper end near the rear of the first gear 41 fixedly connected to a second rotating shaft 47, a sleeve 48 fixedly connected to the outer side of the second rotating shaft 47, two groups of symmetrical fan-shaped rotating plates 49 fixedly connected to the outer side of the sleeve 48, and rubber pads 410 fixedly connected to the symmetrical sides of the two groups of fan-shaped rotating plates 49.

[0036] Specifically, the first gear 41 is rotated by the second rotating shaft 47 in conjunction with the sleeve 48. The sleeve 48 gradually delivers the bottle body 11 from the bottle feeding machine body 3 to the first conveyor belt 2 by rotating the linked fan-shaped rotating plate 49, and pushes away the remaining crowded bottle bodies 11 through the fan-shaped arc surface to avoid congestion. The rubber pad 410 prevents the bottle body 11 from being pushed by the fan-shaped rotating plate 49 and causing collision.

When the bottle body 11 is pushed forward, the position of the bottle cap ring 12 may cause the second infrared probe 518 to be unable to align with the first signal receiver 520, so that the second electric telescopic rod 519 cannot receive the signal instruction, and the second motor 513 is started, so that the output shaft of the second motor 513 is linked to the third gear 512 through the third rotating shaft 511 to rotate outside the outer gear ring 57 The second mounting plate 510 is assisted to slide by the first roller 59, the limit block 521 cooperates with the fixing ring 58 to limit the position of the second mounting plate 510, and the second mounting plate 510 is linked to another group of second mounting plates 510 to slide synchronously by connecting the arc strip 516, so that the parallel third mounting plate 514 and the second infrared probe 518 rotate synchronously, so that the second infrared probe 518 switches to different angles to align with the first signal receiver 520, and then when a signal is given, the second electric telescopic rod 519 passes through the bottle cap ring 12, and the first electric telescopic rod 54 is linked to the lower structure through the cross bracket 55 and the first connecting rod 56 to lift and disengage.

[0039] In this embodiment, the third mounting plate 514 and the fourth mounting plate 515 are fixedly connected to the opposite sides of the two groups of second mounting plates 510, respectively. A second infrared probe 518 is installed on the inner side of the third mounting plate 514, and a second electric telescopic rod 519 is installed below the second infrared probe 518 on the inner side of the third mounting plate 514.

A fixing hole 517 is opened below the first signal receiver 520 on the inner side of the fourth mounting plate 515, and the fixing hole 517 fits with the output shaft of the second electric telescopic rod 519.

[0040] Specifically, if it is found that the bottle body 11 is defective and is an unqualified product, the first electric telescopic rod 54 is started, the cross bracket 55 is linked to the lower mechanism to move downward, the output laser of the second infrared probe 518 is aligned with the first signal receiver 520, and the second electric telescopic rod 519 is started so that its output shaft passes through the bottle cap ring 12 and enters the fixing hole 517, the first electric telescopic rod 54 is started again to lift it upward, after the bottle body 11 is separated from the chain 42, the third motor 522 is started to rotate the L-shaped mounting tube 52, the first infrared probe 53 is aligned with the second signal receiver 9 and gives a signal, the third motor 522 stops, the L-shaped mounting tube 52 rotates 180 degrees, the first electric telescopic rod 54 opens downward, the length of the second electric telescopic rod 519 is shortened and separated from the bottle cap ring 12, the bottle body 11 is placed on the upper end of the second conveyor belt 8 for recycling, the third motor 522 is started again to rotate 180 degrees in the opposite direction, the first infrared probe 53 is aligned with the third signal receiver 15 and sends a signal to stop the third motor 522.

[0041] In this embodiment, the calibration mechanism 6 includes a second bracket 61 fixedly connected to the first bracket 1, a fourth motor 62 is installed at the rear end of the second bracket 61, the inner side of the second bracket 61 is rotatably connected to the fourth rotating shaft 63, the output shaft of the fourth motor 62 is fixedly connected to the fourth rotating shaft 63, the front end of the fourth rotating shaft 63 is fixedly connected to a baffle 64, the front end of the baffle 64 is fixedly connected to a rotating ring 65, the inner ring of the rotating ring 65 is slidably connected to the second roller 612, the front end of the second roller 612 is rotatably connected to the first positioning block 68 through the rotating shaft, the inner side of the first positioning block 68 is slidably connected to the first sliding rod 66, the first sliding rod 66 is slidably connected to the second bracket 61, one side of the first positioning block 68 is rotatably connected to the first threaded rod 69, and one end of the first threaded rod 69 is fixedly connected to the first rotating rod 610.

[0042] Specifically, after the bottle body 11 passes through the main body 10 of the sleeve labeling machine, the outer side will be covered with an outer packaging. The existing sleeve labeling machine main body 10 will have a certain inclination when sleeve labeling. The fourth motor 62 installed at the rear end of the second bracket 61 is started, so that the output shaft of the fourth motor 62 is linked to the baffle 64 and the rotating ring 65 through the fourth rotating shaft 63 to rotate in the same way as the eccentric wheel. When the rotating ring 65 rotates, the label sleeve on the outer side of the bottle body 11 slides downward due to friction, and the second roller 612 rotates on the inner wall of the rotating ring 65. After the diameter of the inner wall of the rotating ring 65 changes, the second roller 612 will move the first slide bar 66 up and down on the inner side of the second bracket 61 through the first positioning block 68. The first positioning block 68 slides on the outer side of the first slide bar 66 to adjust the spacing, and the first rotating rod 610 is rotated to make the first threaded rod 69 press the first slide bar 66, so as to control the position of the first slide bar 66 and the first positioning block 68 to be fixed.

[0046] Specifically, the limiting plate 616 is connected to the first sliding rod 66 via the second connecting rod 617 to move up and down to press the label sleeve outside the bottle body 11 so that the label sleeve remains parallel.

[0047] Working principle: when in use, place the bottle 11 on the upper end of the bottle feeding machine body 3, start the bottle feeding machine body 3 to send the bottle 11 to the first conveyor belt 2, start the first motor 411 to make the first gear 41 drive the chain 42, and the two groups of chains 42 rotate forward in parallel. The second rotating shaft 47 is driven by the first gear 41 to link the sleeve 48 to rotate synchronously, and then the two groups of fan-shaped rotating plates 49 are rotated, so that the bottle 11 on the upper end of the bottle feeding machine body 3 is gradually pushed to the upper end of the first conveyor belt 2, so that the bottle 11 can be gradually The bottle 11 is sent to the first conveyor belt 2 to avoid congestion, and the rubber pad 410 is used to prevent the bottle 11 from being pushed by the fan-shaped rotating plate 49 and causing collision. After the bottle 11 enters the first conveyor belt 2, it is clamped by the clamping teeth 43 on both sides through the rotation of the chain 42 to prevent the bottle 11 from falling on the first conveyor belt 2 when the label is put on, causing congestion of the bottle 11.

After the bottle body 11 is separated from the chain 42, the third motor 522 is started to rotate the L-shaped mounting tube 52. After the first infrared probe 53 is aligned with the second signal receiver 9 and gives a signal, the third motor 522 stops, the L-shaped mounting tube 52 rotates 180 degrees, the first electric telescopic rod 54 opens downward, shortens the length of the second electric telescopic rod 519 and separates it from the bottle cap ring 12, and puts the bottle body 11 into the upper end of the second conveyor belt 8 for recycling, and the third motor 522 is started again to rotate 180 degrees in the opposite direction. After the first infrared probe 53 is aligned with the third signal receiver 15, a signal is sent to stop the third motor 522.

[0048] When the bottle body 11 is pushed forward, the position of the bottle cap ring 12 may cause the second infrared probe 518 to be unable to align with the first signal receiver 520, so that the second electric telescopic rod 519 cannot receive the signal instruction, and the second motor 513 is started, so that the output shaft of the second motor 513 is linked to the third gear 512 through the third rotating shaft 511 to rotate on the outside of the outer gear ring 57, and the second mounting plate 510 is assisted to slide by the first roller 59, and the limit block 521 and the fixing ring 58 cooperate with each other to limit the position of the second mounting plate 510, and the second mounting plate 510 is linked to another group of second mounting plates 510 to slide synchronously by connecting the arc strip 516, so that the parallel third mounting plate 514 and the second infrared probe 518 rotate synchronously, so that the second infrared probe 518 switches to different angles to align with the first signal receiver 520, and then when the signal is given, the second electric telescopic rod 519 passes through the bottle cap ring 12, and the first electric telescopic rod 54 is linked to the lower structure of the first connecting rod 56 through the cross bracket 55 to lift and disengage.

[0049] When the bottle body 11 passes through the main body 10 of the sleeve labeling machine, the outer side will be covered with an outer package. The existing sleeve labeling machine main body 10 will have a certain inclination when sleeve labeling. The fourth motor 62 installed at the rear end of the second bracket 61 is started, so that the output shaft of the fourth motor 62 is linked to the baffle 64 and the rotating ring 65 through the fourth rotating shaft 63 to rotate in the same way as the eccentric wheel. When the rotating ring 65 rotates, the sleeve on the outer side of the bottle body 11 slides downward due to friction, and the second roller 612 rotates on the inner wall of the rotating ring 65. After the diameter of the inner wall of the rotating ring 65 changes, the second roller 612 will move the first slide bar 66 up and down on the inner side of the second bracket 61 through the first positioning block 68, and reset by the spring 67. The limit plate 616 limits the first slide bar 66. The position of the rod 66 is prevented from being misaligned. When the first slide bar 66 slides back and forth, it is linked to the pressure plate 618 by the second connecting rod 617 to move up and down, thereby pressing the standard sleeve on the outside of the bottle body 11 downward to make the standard sleeve parallel. The first positioning block 68 slides on the outside of the first slide bar 66 to adjust the spacing, and then the first threaded rod 69 is rotated by the first rotating rod 610 to press and fix the first slide bar 66, thereby controlling the pressing frequency of the pressure plate 618. The second slide bar 611 prevents the first slide bar 66 from deflecting. The second slide bar 611 is used to fix the position of the first slide bar 66, adjust the position of the second positioning block 613, and rotate the second rotating rod 615 to use the second threaded rod 614 to press the second slide bar 611, so as to adjust the sliding frequency of the first slide bar 66.

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
