Description

Technical Field

[0001] The invention relates to a labeling machine, in particular to a labeling mechanism used in the labeling machine. Background Art

[0002] In the prior art, there are two methods of labeling products: manual labeling and automatic labeling. Manual labeling requires manual separation of the label tape and the label backing paper, and then affixing the separated label to the product. However, manual labeling not only increases labor and labor costs, but also causes labeling errors and unqualified labeling. Automatic labeling uses a labeling machine for labeling. The labeling mechanism of the labeling machine currently on the market needs to cut the label tape into sections of labels, separate the labels, and then convey the separated labels to the labeling area via a conveyor belt. The suction cup installed in the labeling area will absorb the label on the conveyor belt, and finally the label on the suction cup will be attached to the product to complete the labeling. However, this type of labeling machine has a labeling mechanism with many processes and is inconvenient to operate, resulting in low labeling efficiency. Summary of the invention

[0003] Purpose of the invention: In order to overcome the defects of the prior art, the present invention provides a labeling mechanism applied to a labeling machine, which can realize fully automatic labeling, so that the labeling efficiency is high, the labeling qualification rate is high, and the structure is simple and the operation is convenient.

[0004] The technical solution of the present invention is: a labeling mechanism applied to a labeling machine, characterized in that it comprises a labeling bracket, on which a discharge cylinder, a conveying device, a label separator, a cutting device, a suction nozzle and a receiving cylinder are provided.

[0013] By adopting the above technical solution, the labels are transported, separated, cut and adsorbed in the assembly line in sequence. Finally, the label adsorbed on the suction nozzle is moved toward the product and attached to the product to complete the labeling of the product. The labeling is fully automatic and does not require manual operation. It is more convenient and efficient. The separated label backing paper is recycled using a collecting drum, which is energy-saving, environmentally friendly and keeps clean.

[0037] like Figure 1-5 As shown, Figure 2 The direction indicated by the middle line a is the front-to-back direction. A labeling mechanism used in a labeling machine includes a labeling bracket 1, on which a discharge cylinder 2, a conveying device 3, a label separator 4, a cutting device 5, a suction nozzle 6 and a receiving cylinder 7 are provided.

[0038] in,

[0039] A discharge cylinder 2, used for winding up the label tape 8;

[0040] The conveying device 3 is used to convey the label tape 8 on the discharge cylinder 2 toward the label separator 4;

[0041] A label separator 4, used for separating the label tape 8 into a label 81 and a label backing paper 82;

[0042] A cutter device 5, used to cut off the separated labels 81;

[0043] A suction nozzle 6, used for sucking the cut label 81;

[0044] A receiving drum 7, used for rolling up the separated label backing paper 82;

[0045] The cutter device 5 is arranged between the label separator 4 and the suction nozzle 6. The labeling bracket 1 is also provided with a first driving member for driving the suction nozzle 6 to move forward after the label is adsorbed to attach the label 81 to the product. The first driving member can be a cylinder or a motor. The assembly line working method is adopted. The label tape 8 on the discharge cylinder 2 is firstly conveyed to the label separator 4 by the conveying device. The label tape 8 is automatically separated into the label 81 and the label backing paper 82 by the label separator 8. After the label backing paper 82 is separated, it will be conveyed to the receiving cylinder 7. The label 81 is then conveyed to the product direction, and the label 81 slides onto the suction nozzle 6. After the label 81 slides onto the suction nozzle 6, the cutter device starts to work to cut the label 81, so that the label 81 on the suction nozzle 6 is disconnected from the label separator 4. Then the first driving member drives the suction nozzle 6 to move toward the product direction, and finally the label 81 is attached to the product, thereby completing the labeling of the product. The labeling mechanism is fully automatic, does not require manual operation, is more convenient and efficient, and the separated label backing paper 82 is recycled using the receiving drum 7, which is energy-saving and environmentally friendly and keeps clean.

[0046] In this embodiment, the front side of the suction nozzle 6 forms a label suction surface 61, and a guide sleeve 62 is further provided on the suction nozzle 6 at the outer periphery of the label suction surface 61. The guide sleeve 62 is provided with a guide groove 621 for the label 81 to enter the label suction surface 61. The front side of the guide sleeve 62 is located at the front side of the label suction surface 61. A reset spring 63 for resetting the guide sleeve 62 forward after labeling is completed is further provided between the suction nozzle 6 and the guide sleeve 62. The setting of the guide sleeve 62 and the guide groove 621 facilitates the cut label 81 to fall onto the label suction surface 61, making the label 81 flat and convenient for subsequent labeling. The guide sleeve 62 is located at the front side of the label suction surface 61. The front side of the label suction surface 61 can prevent the label 81 from falling. When the first driving member drives the suction nozzle 6 to move forward, the guide sleeve 62 first contacts the product. When the suction nozzle 6 continues to be driven forward, the guide sleeve 62 cannot move forward but will be pressed backward. In this way, the label suction surface 61 is located on the front side of the guide sleeve 62, so that the label 81 adsorbed on the label suction surface 61 can be attached to the product. After labeling is completed, when the first driving member drives the suction nozzle 6 to move backward, the reset spring 63 will reset the guide sleeve 62 forward to the front side of the label suction surface 61. This arrangement makes it more convenient for the label 81 to be attached, saving time and effort.

[0047] In this embodiment, the cutter device includes a first cutter 51 and a second cutter 52 which are arranged opposite to each other. At least one second driving member is provided on the labeling bracket 1 for driving one of the cutters to move in the direction of the other cutter. The second driving member drives one of the cutters to move in the direction close to the other cutter, so that the label 81 separated by the label separation member 4 and the label 81 in the suction surface 61 can be cut and cut. After the cutting is completed, the second driving member drives one of the cutters to move in the direction away from the other cutter, so that the next cutting can be carried out. In the above, the second driving member drives one cutter to move, and the other cutter remains stationary. Of course, two second driving members can also be provided, which can simultaneously drive the two cutters to move together. The second driving member drives the first cutter 51 and the second cutter 52 to move towards each other, and the label 81 can also be cut. After the cutting is completed, the second driving member drives the first cutter 51 and the second cutter 52 to move away from each other, so that the two cutters are separated, which is convenient for the next cutting. Cutting with the cutter is more convenient, labor-saving, and the cutting is smoother. The second driving member drives the two mounting seats to move more conveniently and efficiently. The first cutter 51 is provided with a blade 511, and the second cutter 52 is provided with a corresponding knife groove 521. The blade 511 is inserted into the knife groove 521 to cut the label 81. When the second driving member drives the first cutter 51 or the second cutter 52 to move, the blade 511 is inserted into the knife groove 521 to cut the label 81, or the two cutters can move at the same time. This arrangement makes the cut label 81 flat, which is convenient for subsequent labeling. Of course, the second cutter 52 can also be provided with a blade, and the first cutter 51 is provided with a corresponding knife groove.

The first cutter 51 and the second cutter 52 are arranged below the label separation port 42. After the label tape 8 comes out of the conveying channel, it enters the label separation channel from the label tape inlet 41 and continues to be conveyed in the direction of the label separation port 42. Because the label separation port 42 is provided with a label separation surface 421 arranged in the direction of the receiving drum 7, the label base paper 82 is conveyed in the direction of the receiving drum 7, and the label 81 is conveyed in the direction of the first cutter 51 and the second cutter 52. It is more convenient to separate the label tape 8 in this way, and no manual separation is required, which saves time and effort, and realizes full-automatic labeling.

[0050] In this embodiment, the labeling bracket 1 is provided with a fourth driving member for driving the receiving drum 7 to work and a plurality of first guide wheels 12 for conveying the label base paper 82 separated by the label separation port to the receiving drum 7. The first guide wheels 12 are arranged at intervals between the label separation member 4 and the receiving drum 7. The fourth driving member drives the receiving drum 7 to rotate to recycle the label base paper 82. A plurality of first guide wheels 12 are arranged at intervals between the receiving drum 7 and the label separation member 4, which not only facilitates the conveyance of the label base paper 82, but also prevents the accumulation of the label base paper 82.
