[0027] The placing cylinder 18 is fixed to the labeling machine frame 17 by a seat bearing and a top screw. After the placing cylinder 18 passes through the seat bearing, a synchronous pulley is installed on the rear end rotating shaft. The conveying limiting wheel 20 is connected to the labeling machine frame 17 by a threaded connection and locked with a nut. The bottom paper recovery cylinder 19 is fixed to the labeling machine frame 17 by a seat bearing and a top screw. After the bottom paper recovery cylinder 19 passes through the seat bearing, a synchronous pulley is installed on the rear end rotating shaft. The labeling head 22 is fixed to the labeling machine frame 17 by two hexagon socket screws. The servo motor 21 is fixed to the labeling machine frame 17 by four hexagon socket screws. Two synchronous pulleys are installed on the rotating shaft of the servo motor 21. The servo motor 21 is linked to the placing cylinder 18 and the bottom paper recovery cylinder 19 through a synchronous belt and a synchronous pulley.

[0028] The labeling machine frame 17 is symmetrically provided with conveying limiting wheels 20 , and the label paper 13 conveyed from the whole roll of label paper 14 is wound on the bottom paper recovery drum 19 through the upper and lower conveying limiting wheels 20 .

[0029] like Figure 2-3 As shown, the heating assembly includes a PE tubular film heating lamp 3 and a label heating lamp 5. The PE tubular film heating lamp 3 and the label heating lamp 5 are respectively fixed to a PE tubular film heating lamp hose bracket 8 and a label heating lamp hose bracket 9. The PE tubular film heating lamp hose bracket 8 and the label heating lamp hose bracket 9 are both fixed on a temperature control meter 10, wherein the PE tubular film heating lamp hose bracket 8 and the label heating lamp hose bracket 9 can be bent and deformed at will, so that the direction and angle of the PE tubular film heating lamp 3 and the label heating lamp 5 can be adjusted at will; the PE tubular film heating lamp 3 and the label heating lamp 5 are both electrically connected to the temperature control meter 10.

[0030] Specifically, the PE tubular film heating lamp 3 is threadedly connected to the PE tubular film heating lamp hose bracket 8, which is then fixedly connected to the tubular film packaging machine 2 via threads and two nuts. The label heating lamp 5 is threadedly connected to the label heating lamp hose bracket 9, which is then fixedly connected to the tubular film packaging machine 2 via threads and two nuts.

[0031] In this embodiment, the new model includes an ambient temperature sensor 11, which is arranged on the upper surface of the temperature control meter 10 for sensing the external temperature; wherein the ambient temperature sensor 11 is electrically connected to the temperature control meter 10, wherein the temperature control meter 10 controls the start and stop of the PE tube film heating lamp 3 and the label heating lamp 5 according to the external temperature value received by the ambient temperature sensor 11.

[0032] A label sensing sensor 15 is fixed on the photoelectric sensor fixing frame 16 for sensing whether the label is normally attached. The photoelectric sensor fixing frame 16 is fixed on the labeling machine component 6 .

[0033] The temperature control system composed of the temperature control meter 10, the ambient temperature sensor 11 and the heating lamp can automatically control the start and stop of the heating lamp according to the changes in the external ambient temperature in time, avoiding abnormal label pasting caused by manual failure to turn on the heating lamp.

[0034] In this embodiment, an audible and visual alarm indicator light 1 is provided on the right side of the tubular film packaging machine 2 for outputting an abnormality alarm. The audible and visual alarm indicator light 1 is connected to the tubular film packaging machine 2 by four hexagon socket screws.

[0035] In this embodiment, the device includes a rubber-pressing wheel 12, which is assembled from a bearing, a rubber-coated wheel sleeve, a rotating shaft, and a fixed frame. The bearing-coated wheel sleeve allows for free rotation on the rotating shaft. The wheel 12 is securely connected to the labeling machine assembly 6 via a screw and a nut. Loosening the screw and nut adjusts the height of the wheel 12. The angle of the wheel 12 is controlled by the angle of the bearing-coated wheel sleeve on the rotating shaft, thereby varying the force of the label pressure and ensuring stable label pressure.

[0036] The specific implementation process of the utility model device in the production process is as follows:

[0037] First, place the whole roll of PE tubular film 4 on the tubular film packaging machine 2, then pull out the PE tubular film and thread it on the tubular film packaging machine 2. At the same time, place the whole roll of label paper 14 containing printed product information on the placement cylinder 18 of the labeling machine assembly 6, and pull out the labels and thread them in a fixed order and wrap them on the bottom paper recovery cylinder 19.

[0038] Then adjust the pressure of the label pressing rubber wheel 12, and at the same time bend the PE tube film heating lamp hose bracket 8, adjust the direction and angle of the PE tube film heating lamp 3 so that it heats the PE tube film 7 pulled out from the labeling location; at the same time, bend the label heating lamp hose bracket 9 and adjust the direction and angle of the label heating lamp 5 so that it heats the label paper at the labeling location;

[0039] Then set the temperature at which the heating lamp starts on the temperature control table 10, and finally start the entire device.

[0040] When the ambient temperature sensed by the ambient temperature sensor 11 is higher than the set value of the temperature control table 10, it means that the external ambient temperature meets the adhesion requirements of the PE tubular film and the label, the PE tubular film heating lamp 3 and the label heating lamp 5 do not work, the tubular film packaging machine 2 normally makes bags, drives the pulled PE tubular film 7 to move to the left, the labeling machine assembly 6 normally labels, the label is automatically separated from the conveyed label paper 13 and attached to the pulled PE tubular film 7, the label pressing rubber wheel 12 rolls the label to improve the adhesion strength, the PE pipe fitting product is manually placed into the packaging bag made by the tubular film packaging machine with the label, and the tubular film packaging machine 2 then seals the packaging bag to make a bagged product;

[0041] When the ambient temperature sensed by the ambient temperature sensor 11 is lower than the set value of the temperature control table 10, indicating that the external ambient temperature does not meet the adhesion requirements of the PE tubular film and the label, the PE tubular film heating lamp 3 and the label heating lamp 5 are turned on to heat the PE tubular film and the label paper at the labeling location respectively. Then, the tubular film packaging machine 2 continues to make bags normally, driving the PE tubular film being fed out to move to the left. The labeling machine 6 continues to apply labels normally. The label is automatically separated from the label paper 13 and attached to the PE tubular film 7 being fed out. The label pressing rubber wheel 12 rolls the label to improve adhesion. The PE pipe fitting product is manually placed into the packaging bag made by the tubular film packaging machine with the label attached. The tubular film packaging machine 2 then seals the packaging bag to form a finished bag. This process repeats.

[0042] If during this process, the label sensing photoelectric sensor 15 senses that the label is missing, it means that the label paper has run out or the label has not been peeled off from the label paper normally, and other abnormal conditions have occurred. At this time, the equipment stops running, the sound and light alarm indicator light 1 sounds a sound and light alarm, and the equipment system also outputs a corresponding alarm problem. After the manual receiving the alarm signal and handling the problem, the equipment and device operation are restored, and the device operation is completed.

[0043] The advantages of this utility model are: novel design and reasonable conception. It mainly has the function of heating the PE tube film and the label paper to improve the adhesion between the two and can identify whether the label is normally affixed to prevent missing labels. At the same time, it has a simple structure, saves costs, has minimal dependence on the environment, is easy to operate, and is convenient to operate.
