[0046] Figure 1 A perspective view of the flexible supply system for label printing and film covering according to the present application is shown in FIG. 1, and a perspective view of the flexible supply system for label printing and film covering according to the present application is shown in FIG. 2. Figure 1 The flexible supply system for label printing and film covering according to the present application comprises a label printing device 10, a label transfer device 20, a label film covering device 30, a support assembly 40, and a control device. The label printing device 10, the label transfer device 20, the label film covering device 30, and the control device are mounted on the upper surface of the support assembly 40, and the support assembly 40 is fixed to the ground.

[0047] The label printing device 10 is used to print labels required in the production process, and the labels are printed with necessary information and the label backing paper is peeled off after printing, that is, the printed label has information printed on one side and is in an adhesive state on the other side. The printed label is output from the label outlet of the label printing device 10 and falls on the label suction cup of the label transfer device 20, waiting for the next operation.

[0048] The label transfer device 20 adsorbs and positions the received label, and then transfers the received label to the label film covering device 30 for film covering treatment, and the label is subjected to film covering treatment at the label film covering device 30.

[0050] In an embodiment, the printer mounting assembly 12 comprises a fixed mounting plate 121, a sliding platform plate 122, a sliding assembly 123, and a locking assembly 124. The fixed mounting plate 121 is provided with mounting holes for fastening the fixed mounting plate 121 to the support assembly 40 by fasteners. The top of the sliding platform plate 122 is fixedly connected to the printer 11, and the bottom of the sliding platform plate 122 is movably connected to the fixed mounting plate 121 by the sliding assembly 123. In this way, the printer 11 can be moved smoothly, so that the printer 11 can be moved according to the situation during the production process. Specifically, the sliding assembly 123 can be in the form of a guide rail and a sliding block. Since the position of the printer 11 needs to be relatively fixed during the production process to ensure the accuracy of the entire system, the printer mounting assembly 12 comprises a locking assembly 124 for locking the relative position of the sliding platform plate 122 and the fixed mounting plate 121, thereby indirectly fixing the relative position of the printer 11.

[0072] In an embodiment, a limiting structure is arranged on one side of the end fixing plate 315, which is used to act with the limiting structure on the fixed mounting base plate 310, so as to prevent the device from breaking through the limit position during the sliding process.

[0073] In an embodiment, the label film covering device 30 is further provided with a latching mechanism, which is used to lock the movable sliding vertical plate.

[0074] In an embodiment, a handle is further arranged on one end of the first sliding vertical plate 312 and the second sliding vertical plate 313, which facilitates the pushing and pulling of the movable components. Meanwhile, a protection device is arranged on the end of the first sliding vertical plate 312 and the second sliding vertical plate 313, which prevents the operator's hand from being accidentally injured.

[0075] It can be understood that the above-mentioned cylinders are all equipped with electromagnetic valves, so as to control the extension and retraction actions of the cylinders.

[0076] Figure 8 A perspective view of the supporting assembly 40 is shown, which is arranged on the fixed mounting base plate 310. Figure 8It can be seen that the support assembly 40 comprises a support frame 401, a ground foot 402, a door handle 403, a mounting plate 404, and a door 405. The mounting plate 404 is provided with the label printing device 10, the label transfer device 20, the label film covering device 30, and the control device. The ground foot 402 is arranged at four corners of the support frame 401 and is used for supporting the support frame 401. The support frame 401 is composed of support rods and the openable and closable door 405, so as to facilitate an operator to open the support assembly 40 from four sides for inspection and maintenance work.

[0077] In an embodiment, the control device comprises a first sensor for detecting the presence of a label on the label suction disc 211. When the label is present, the first sensor transmits a label presence signal to the control device, and the control device controls the first cylinder 2121 and the second cylinder 2131 to act, so as to drive the first positioning plate 2120 and the second positioning plate 2130 connected thereto, respectively, to be closed, so as to correct the position of the label. When the label position correction is completed (which can be determined according to a preset time), the control device controls the longitudinal displacement cylinder 2210 to act, so as to displace the label suction disc 211 to a first position. The label presence signal is referred to as a first sensor signal, and the first position is located above the servo sliding table 2220.

[0078] In an embodiment, the control device further comprises a second sensor. When the label suction disc 211 is displaced to the first position, the second sensor is triggered to generate a second sensor signal. After the control device receives the second sensor signal, the control device controls the servo motor 2222 to operate, so that the servo sliding table 2220 drives the components connected thereto to operate, so as to displace the label suction disc 211 to a second position. The second position is located directly below the pressure roller 363.

[0079] In an embodiment, the control device further comprises a third sensor. When the label suction disc 211 is displaced to the second position, the third sensor is triggered to generate a third sensor signal. After the control device receives the third sensor signal, the control device controls the pressing cylinder 340 to act, so as to abut the second pressing plate 342 against the first pressing plate 341, thereby pressing the film tape, and controls the base paper peeling motor 352 and the driving motor of the base paper recycling assembly 37 to act. The base paper peeling tongue 351 retreats and the base paper recycling disc 371 rotates to cooperate with each other to peel the film base paper, and the film falls on the label of the label suction disc 211.

[0080] In an embodiment, the control device further comprises a fourth sensor for detecting whether there is a barrier between the pressure roller 363 and the label suction disc 211. If there is no barrier between the pressure roller 363 and the label suction disc 211 (at this time, the base paper peeling tongue 351 retreats), the fourth sensor sends a fourth sensor signal. After the control device detects the fourth sensor signal, the control device controls the film cylinder 361 to act, so as to drive the pressure roller to move downward, so as to press the film on the surface of the label, thereby realizing the film covering operation of the label.
