[0003] In the related art, the automatic labeling machine needs to evenly place the products to be labeled in the bottle slots of the turntable, and the rotation of the labeling wheel drives the label paper to rotate, and the label paper is attached to the product through the rotation of the labeling wheel.
[0004] However, the number of bottle slots on the turntable is limited. Each time a round of product labeling is performed, the turntable needs to be stopped and new products to be labeled are placed before the next round of product labeling can be performed, which affects the labeling speed, making the labeling slow and labor-intensive. Utility Model Content

[0056] The following is combined with Figure 1 -Attached Figure 5 , further details of this application are given.
[0057] The embodiment of the present application discloses an automatic labeling device for cosmetic bottles.
[0058] Reference Figure 1 , Figure 2 and Figure 3, a cosmetic bottle automatic labeling device, comprising a conveyor belt 10, a label warping plate 20, a rotating wheel 30, an abutment 40, a fixing member 50, a first driving member 60, a waste collecting roller 70, a paper discharging roller 80, a tensioning device 90, a collecting device 100, a base 110, a fixing seat 120 and a sensor 130, the conveyor belt 10 can transport products, the label warping plate 20 is located at one side of the conveyor belt 10, when the label paper 140 abuts against the label warping plate 20, one end of the label is separated from the label paper 140, when one end of the label is attached to the product, the rotating wheel 30 drives the product to rotate, the fixing member 50 is located at the other end of the conveyor belt 10, and abuts against the product when the rotating wheel 30 drives the product to rotate to limit the product, the abutment 40 is located between the label warping plate 20 and the rotating wheel 30, the abutment 40 prevents the label from being attached to the rotating wheel 30 under the drive of the rotating wheel 30, and the first driving member 60 drives the label paper 140 to stretch the length of a label at regular intervals.
[0059] The product is transmitted from one end of the conveyor belt 10 to approach the label warping plate 20. The label paper 140 abuts against the label warping plate 20 under the pulling force of the first driving member 60. About one-third of one end of the label on the label paper 140 is separated from the label paper 140, and the label is tilted. The product is close to the tilted label. The abutting member 40 can be a brush plate 41. The product transported forward is more closely attached to the peripheral side of the product through the brush plate 41. The product is transported forward a little and abuts against the rotating wheel 30. It also includes a third driving member, which is fixedly connected to the rotating wheel 30. At this time, the brush plate 41 can prevent the label from being driven by the rotating wheel 30 to fit with the rotating wheel 30 when it is separated from the label paper 140 but not completely attached to the product, thereby preventing damage to the viscosity of the label paper 140.
[0060] The third driving member can be a third motor, which drives the rotating wheel 30 to rotate counterclockwise, driving the product to rotate clockwise. The fixing member 50 can limit the product to prevent the product from being relatively displaced with the conveyor belt 10 driven by the rotating wheel 30. The label that is attached to the product but has not completely fallen off the label paper 140 is completely attached to the clockwise rotating product through the contact of the brush plate 41, and the label falls off the label paper 140. The brush of the brush plate 41 sweeps over the label that is completely attached to the product, making the label and the product fit more closely.
[0061] The product is transported from one end of the conveyor belt 10 in a state of waiting to be labeled, and is transported away from the other end of the conveyor belt 10 after labeling is completed. There is no need to stop the labeling process to transport the product to be labeled, which solves the problem of slow labeling rhythm and labor-consuming labeling speed caused by the need to stop the turntable after the automatic labeling machine completes labeling of the product placed on the turntable and then put in a new product to be labeled.
[0062] Reference Figure 1With the label paper 140 moving forward as the front, the label paper 140 is discharged from the left end of the paper discharge roller 80, bypasses the right end of the tensioning device 90, then bypasses the left end of the label warping plate 20, and then bypasses the right end of the collecting device 100 and the left end of the waste collecting roller 70.
[0063] Reference Figure 1 The first driving member 60 is connected to the waste collecting roller 70. The first driving member 60 can be driven by a first motor 61, and the waste collecting roller 70 reels the label paper 140. The first motor 61 drives the waste collecting roller 70 to stretch the label paper 140 by the length of a label at regular intervals.
[0064] Reference Figure 1 , Figure 2 and Figure 3 The collecting device 100 includes a fourth roller 101 and a fifth roller 102, and the label paper 140 can be respectively in contact with the fourth roller 101 and the fifth roller 102. After the label paper 140 is separated from the label at the label warping plate 20, it goes around to the fourth roller 101, and with the running direction of the label paper 140 as the front, the label paper 140 goes around from the left end of the fourth roller 101 to the right end of the fifth roller 102, and then winds with the waste collection roller 70 from the left end of the fifth roller 102. The first motor 61 drives the waste collection roller 70 to stretch a label length at regular intervals, so that the label paper 140 is stretched and fed forward by a certain length each time a label is removed. When the product after labeling is separated from the rotating wheel 30, the next label on the label paper 140 that has moved forward by a certain length is separated from the label warping plate 20 by about one third, and just fits with the next product to be labeled.
[0065] Reference Figure 1 The specific structure of the fixing member 50 and the specific connection relationship between the fixing member 50 and the product are as follows: the fixing member 50 includes a second driving member 51, a shell 52 and a rotating shaft 53. The second driving member 51 is fixedly connected to the shell 52. There are multiple rotating shafts 53, and the multiple rotating shafts 53 are evenly distributed at the same radius of the shell 52. The multiple rotating shafts 53 are connected to the shell 52 in a circular rotation, and the rotating shafts 53 can abut against the product.
[0066] The second driving member 51 can be a second motor 511, which drives the shell 52 to rotate. The multiple rotating shafts 53 fixedly connected to the shell 52 can make circular motion with the center of the shell 52 as the center. When the product rotates driven by the rotating wheel 30, the rotating shafts 53 abutting against the product rotate.
[0067] Reference Figure 4 and Figure 5 The sensor 130 is located at one side of the rotating wheel 30 , the sensor 130 is electrically connected to the first driving member 60 , and the sensor 130 is electrically connected to the second driving member 51 .
[0068] The sensor 130 monitors the product labeling status. When the product labeling is completed, the second motor 511 connected to the sensor 130 drives the housing 52 to rotate a short distance, driving the rotating shaft 53 in contact with the product to move in a circular motion. The rotating shaft 53 moves in a circular motion to push the product in contact with the rotating shaft 53 to move a distance on the conveyor belt 10.
[0069] The first motor 61 connected to the sensor 130 drives the label paper 140 to move forward by a label length, just so that the label paper 140 that has taken off a label moves forward by a label length, so that the next label can be applied.
[0070] Reference Figure 1 , Figure 4 and Figure 5 , the paper discharge roller 80 is fixed on the fixed seat 120, the specific structure of the tensioning device 90 and the specific connection relationship between the paper discharge roller 80, the label paper 140 and the label warping plate 20 are as follows: the tensioning device 90 includes a moving roller 91, a first roller 92, a second roller 93, a third roller 94, a limit seat 95, a swing rod 96 and a first elastic member 97, the paper discharge roller 80, the first roller 92, the second roller 93 and the third roller 94 are all fixedly connected to the base 110, with the running direction of the label paper 140 as the front, the label paper 140 goes from the left end of the paper discharge roller 80 to the right end of the first roller 92, then goes to the left end of the moving roller 91, passes through the left end of the second roller 93, and then goes to the right end of the third roller 94, and abuts against the label warping plate 20 from the right end of the third roller 94;
[0071] A limiting groove 951 is provided on the limiting seat 95, one end of the swing rod 96 is rotatably connected to the fixed seat 120, and the other end is slidably connected to the limiting groove 951, the movable roller 91 is fixedly connected to the swing rod 96, and a slider 961 is provided on the swing rod 96, and the slider 961 is slidably connected to the limiting groove 951, and the first elastic member 97 connects the side wall of the limiting groove 951 and the slider 961.
[0072] The first elastic member 97 can be a first spring 971. The first motor 61 drives the waste collecting roller 70 to reel up. The pulling force of the label paper 140 at the label warping plate 20 drives the moving roller 91 to move. The slider 961 on the swing rod 96 moves in the limiting groove 951. The first spring 971 is compressed. Due to the movement of the moving roller 91, a section of the label paper 140 at the moving roller 91 moves to the label warping plate 20. The first spring 971 returns to its original position under the elastic action, pulling the label paper 140 at the paper output roller 80 to unroll.
[0073] The implementation principle of the automatic labeling device for cosmetic bottles in this embodiment is as follows: with the running direction of the label paper 140 as the front, the label paper 140 is wound from the left end of the paper discharge roller 80 to the right end of the first roller 92, and then to the left end of the moving roller 91, from the left end of the moving roller 91 to the left end of the second roller 93, and then to the right end of the third roller 94, passing through the label warping plate 20, from the left end of the fourth roller 101 to the right end of the fifth roller 102, and then from the left end of the fifth roller 102 to the waste collecting roller 70, the first motor 61 tightens the label paper 140, the label paper 140 abuts against the label warping plate 20 at the label warping plate 20, the label and the label paper 140 are separated by about one third, the label is warped, and is bonded to the product transported to the label warping plate 20 by the conveyor belt 10, the product continues to move forward on the conveyor belt 10, and under the abutment of the brush plate 41, the label and the product The product continues to move forward on the conveyor belt 10, and the product abuts against the rotating wheel 30 and the rotating shaft 53. The third motor drives the rotating wheel 30 to rotate. The product rotates driven by the rotating wheel 30, and the label paper 140 that has not been separated is pulled to separate from the label. The product information after labeling is recognized by the sensor 130, and the sensor 130 transmits the electrical signal to the first motor 61 and the second motor 511. The first motor 61 drives the waste collection roller 70 to rewind, and stretches a label length at regular intervals. Since the second motor 511 can drive the multiple rotating shafts 53 fixedly connected to the shell 52 to make a circular motion with the center of the shell 52 as the center, the electrical signal of the sensor 130 is transmitted to the second motor 511, driving the second motor 511 to drive the rotating shaft 53 abutting against the product to push the product forward on the conveyor belt 10, thereby facilitating the labeling of the next product to be labeled;
[0074] Every time the first motor 61 stretches a label length, it drives the slider 961 on the movable roller 91 to move in the limiting groove 951 to compress the first spring 971. The driving gap of the first motor 61 causes the first spring 971 to rebound and pull the label paper 140 near the paper output roller 80, so that the label paper 140 is unrolled for a distance.
[0075] The product is transported from one end of the conveyor belt 10 in a state of waiting to be labeled, and is transported away from the other end of the conveyor belt 10 after labeling is completed. There is no need to stop the labeling process to transport the product to be labeled, which solves the problem of slow labeling rhythm and labor-consuming labeling speed caused by the need to stop the turntable after the automatic labeling machine completes labeling of the product placed on the turntable and then put in a new product to be labeled.

The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
