The specific use process of the labeling machine is as follows: firstly, put the product to be labeled on the starting conveyor belt 1, and the starting conveyor belt 1 moves continuously, so as to transport the product to the feeding gap of the lower plate 5, and the motor of the starting conveyor belt 1 does not stop. Under the control of the PLC controller, because if there are too many products, they can be accumulated on the conveyor belt 1 at the beginning, and the upper plate 4 is intermittently rotated by 90 degrees under the drive of the first motor. When one of the feeding gaps 6 and the feeding gap When aligning, the product enters the feeding gap and is stuck by the shifting gap 6, and as the upper plate 4 continues to rotate, the product is dragged to the opposite crossing gap 7, and the product fork moves with the end conveyor belt 2 , the material fork 3 in the vertical section lifts the product up through the fork gap 7 from the lower end, so as to leave the material shifting gap 6, and will touch one of the single rods 10 located directly above during the ascent process, and the single rod 10 The negative pressure groove 14 of the negative pressure groove 14 is adsorbed with labels or trademarks that need to be pasted. The surface of the product is adhered to the colloid in advance. The product pushes the single rod 10 upwards, and the outer sub-rod rotates upwards through the second rotating shaft 12, which will not hinder the product from continuing to move upwards, and then the outer sub-rod returns to its original position under the pull of the spring 13, and the product moves to Upper horizontal section of end conveyor belt 2.

The label-picking mechanism and the label-passing mechanism are described below. The four umbrella-shaped rubber suction cups 18 of the label-picking mechanism also intermittently rotate 90 degrees under the action of the third rotating shaft 21 and the sixth motor 22. When one of the umbrella-shaped rubber suction cups When 18 moves to the upper side of the label groove 20, it moves downward under the action of the cylinder 19 and touches the label in the label groove 20, and then the second negative pressure pump sucks air under the action of the fifth motor to absorb the label to the umbrella-shaped Rubber sucker 18, then rotate to the diagonal position, descend again, and put the label on the negative pressure groove 14 of a single rod 10 of the labeling mechanism. At this time, the negative pressure groove 14 faces upward, and the negative pressure groove 14 The connected first negative pressure pump 15 starts to inhale air under the action of the fourth motor to make the negative pressure groove 14 suck the label, and then the negative pressure groove 14 rotates to the upper part of the fork gap 7 under the action of the first rotating shaft 9, At the same time, under the rotation of the third motor 11, the single lever 10 makes the negative pressure groove 14 face downwards. At this time, the label also faces downwards to meet the products held by the material fork 3. After pasting, the negative pressure groove 14 continues to rotate to the label picking mechanism. At the same time, the notch faces upward and continues to absorb the label through the label transmission mechanism. The single rod 10 and the material shifting gap 6 are aligned up and down, and rotate coaxially, and cooperate to complete the work together under the action of the first motor.

The first motor, the second motor, the third motor 11 , the fourth motor, the fifth motor, the sixth motor 22 and the cylinder 19 are all controlled by the PLC controller, and cooperate together to complete the labeling work under the instructions of the PLC controller. Specifically, the PLC controller controls the rotation of the first motor, so that the first rotating shaft 9 synchronously drives the cross-shaped passing pole and the upper plate 4 to rotate, and at the same time gives commands to the cylinder 19 to complete the work of picking, rotating, and placing the lot, wherein two negative pressure commands are coordinated The pump sucks and deflates air, and commands the third motor 11 to rotate, and the second motor drives the material fork 3 on the end conveyor belt 2 to drag the product collision label to be pasted at a specific time. Repeated control operations like this complete the production line. Carry out labeling work intermittently.

To sum up: the labeling machine realizes the automatic labeling process, and the whole process is operated by controlling the corresponding structure through the PLC controller. The degree of automation is high, the operation is accurate and fast, and it is greatly improved compared with manual operation. It improves production efficiency, saves manpower and material resources, and can ensure that all products on the assembly line are labeled to avoid omissions.
