[0028] For the convenience of understanding, the plan view after label roll is unfolded is as shown in the drawings Figure 2 The upper layer is label paper, the lower layer is covered with release paper, the label is a part of label paper, is provided with indentation around, and is separated from label paper when being subjected to the downward pressing force of label pressing and pasting mechanism 3, so as to be pasted on the surface of paper plastic packaging bag. The feeding and discharging mechanism 2 is used to feed and discharge paper plastic packaging bag in this embodiment, belt conveying line 5 transports paper plastic packaging bag to different stations to complete pasting and marking processes, so as to realize the integrated automatic operation of marking and pasting.

[0029] Example 2:

[0030] The upper and lower feeding mechanism 2 comprises an upper and lower feeding motor 21, a bidirectional screw rod 22 and a guide rail 23. The bidirectional screw rod 22 is fixed to the movable end of the upper and lower feeding motor 21. The length direction of the bidirectional screw rod 22 is consistent with the conveying direction of the belt conveying line 5. The two ends of the bidirectional screw rod 22 are respectively threadedly connected with an upper feeding sliding block 24 and a lower feeding sliding block 25. The upper feeding sliding block 24 and the lower feeding sliding block 25 are both slidingly connected with the guide rail 23. The top of the upper feeding sliding block 24 and the lower feeding sliding block 25 is respectively fixed with an upper feeding lifting cylinder 26 and a lower feeding lifting cylinder 27.

Since the bidirectional screw rod 22 is adopted, the upper feeding and the lower feeding are simultaneously performed, so that the efficient operation of the equipment is ensured.

[0031] Embodiment 3:

[0032] As Figure 5 , the label winding and separating mechanism 9 comprises an upper feeding roller 91, a release paper waste roller 92, a label paper waste roller 93 and a separating guide roller 94 arranged on the mounting plate 8. The upper feeding roller 91, the release paper waste roller 92 and the label paper waste roller 93 are all connected with winding motors. The separating guide roller 94 is composed of two separating rollers which are arranged in parallel and close to each other. One end of the label paper covered with the release paper is wound on the upper feeding roller 91. The release paper and the label paper are separated at the separating guide roller 94. The other end of the release paper is wound on the release paper waste roller 92 after being guided by the left separating roller. The other end of the label paper is wound on the label paper waste roller 93 after being guided by the right separating roller. The right separating roller is further provided with a first guide roller 95 close to the side of the label paper waste roller 93. The bottom of the first guide roller 95 is flush with the right separating roller. The label pressing mechanism 3 is arranged above the middle of the first guide roller 95 and the right separating roller.

[0033] When the label winding and separating mechanism 9 works, the three winding motors synchronously perform the winding work. The upper feeding roller 91 performs the feeding. The label paper covered with the release paper passes between the two separating rollers of the separating guide roller 94 after being guided. At this time, the release paper is wound by the release paper waste roller 92 alone, and the label paper is wound by the label paper waste roller 93 alone. After passing through the separating guide roller 94, the release paper and the label paper are separated. The right separating roller and the first guide roller 95 form a straight section of the label paper. The label paper at this position has been separated from the release paper. After being extruded downward by the label pressing assembly, the label is separated from the label paper and directly adheres to the upper surface of the paper-plastic packaging bag conveyed by the belt conveying line 5.

[0034] Preferably, a second guide roller 96 is arranged between the feeding roller 91 and the left separating roller, and between the left separating roller and the release paper waste roller 92, so that the winding is smoother.

[0035] Embodiment 4:

[0036] Due to different shapes and types of equipment, the size of the adapted paper plastic packaging bag is also different, and the thickness is slightly different. In order to make the label more flatly paste on the surface of the paper plastic packaging bag, the label pressing mechanism 3 is specially designed. The label pressing mechanism 3 includes a high-elasticity silicone material pressing head 31, the top of the pressing head 31 is fixed with a sliding rod 32, the sliding rod 32 is slidingly connected with a sliding sleeve 33, two positioning sliding blocks 34 are symmetrically arranged on both sides of the top of the sliding rod 32, the positioning sliding blocks 34 are slidingly connected with the positioning sliding grooves 35 on both sides of the sliding sleeve 33, a first spring 36 is arranged in the sliding sleeve 33, and the first spring 36 is located at the top of the sliding rod 32. The top of the sliding sleeve 33 is fixedly connected with the movable end of a pressing air cylinder 37.

[0037] The pressing head 31 is made of high-elasticity silicone material, which can deform when contacting the label, so as to cover the entire label and press the label onto the paper plastic packaging bag, thereby preventing the label from being pasted insecurely due to the edge of the label being raised. On the other hand, the flexible contact can also prevent the label or the paper plastic packaging bag from being damaged. In addition, the first spring 36 is arranged, which also adopts a flexible pressing mode, so as to ensure a certain pressing force while avoiding excessive force. In addition, even if the specifications of the paper plastic packaging bag are different and the thickness is slightly different, the label can still be pressed and pasted well.

The label compacting assembly 10 includes two rotating rollers 101 arranged in parallel, a compacting belt 102 is arranged between the two rotating rollers 101, a support plate 103 fixedly connected with the mounting plate 8 is arranged on the inner side of the compacting belt 102, a plurality of guide rods 104 are threadedly connected with the support plate 103, a pressing block 105 is slidingly sleeved at the bottom of the guide rod 104, and a second spring 106 is sleeved on the outer side of the guide rod 104 between the pressing block 105 and the support plate 103. Preferably, the plurality of pressing blocks 105 are arranged in a rectangular array. The structure can further compact the label. The paper plastic packaging bag is conveyed to the lower side of the compacting belt 102 by the belt conveying line 5, so that the pressing block 105 and the second spring 106 are lifted up, the compacting belt 102 is tightly attached to the upper surface of the paper plastic packaging bag, and the compacting belt 102 presses the label. It should be noted that the compacting belt 102 can be provided with a driving assembly to enable it to rotate when necessary. The direction of the compacting belt 102 below is consistent with that of the belt conveying line 5, so that the paper plastic packaging bag is more easily rolled into the space between the compacting belt 102 and the belt conveying line 5.

[0040] The workbench 1 is provided with photoelectric switches near the label pressing mechanism 3, the label compacting assembly 10 and the marking machine 4, and different work stations are identified so as to start and stop the belt conveying line 5 to carry out corresponding operation.

[0041] The top of the workbench 1 is further provided with a control operation display screen 11 for controlling the operation of the whole device, including input and printing of label information.
