The inkjet printer 3 can also be a color printer, which can be effectively adapted by simply changing the color ink cartridge. The inkjet printer 3 also has an alarm reminder and forced shutdown function in case of abnormality.

[0030] The control and display device 8 can perform on-site data entry, or copy data via USB flash drive, or perform remote control via remote data writing.

[0031] As an optional embodiment, the guide wheel group 4 includes four rollers 41, with two rollers at the top and two at the bottom of the inkjet printer 3, so that the labels can be orderly brought to the inkjet printer 3 for inkjet printing.

[0032] As an optional embodiment, the sealing device 7 is a double-button sealing device with a certain distance between the two buttons for cutting the mesh bag. The first button is used to seal the bottom of the mesh bag first, and then convey the material. The second button seals the mesh bag and also seals the note together. Therefore, during the sealing process, the sealing of the first material bag and the sealing of the second button are carried out simultaneously.

[0033] As an optional embodiment, the label feeding device 5 includes a guide plate 51, a stepper motor 52, a label feeding roller 53, and a label pressing roller 54. The stepper motor 52 drives the label feeding roller 53 to rotate. The guide plate 51 is located on both sides of the label feeding roller 53. The label pressing roller 54 presses against the label feeding roller 53. The stepper motor 52 is equipped with a drive gear 55. There are two label feeding rollers 53, and each label feeding roller 53 is fixed with a driven gear 56. The drive gear 55 drives the two driven gears 56 to rotate through a synchronous belt 57. The guide plate 51 is located on one side of the label feeding roller 53 and between the label feeding rollers 53. The guide plate 51 is provided with a through hole 511 for inserting a label. The guide plate 51 of the label feeding device 5 can guide the label and also has a certain function of leveling and straightening the label, and also ensures the accuracy of the fixed-length detection fiber optic device 58.

[0034] As an optional embodiment, the label-pressing roller 54 includes a mounting cover 541, a fixing cover 542, a first support arm 543, a second support arm 544, and a connecting rod 545. The fixing cover 542 is fixed to the frame 1. The first support arm 543 passes through the fixing cover 542 and the frame 1. One end of the first support arm 543 is fitted with a metal coil spring 546, and the other end of the first support arm 543 is fixed with the connecting rod 545. The mounting cover 541 covers the metal coil spring 546. The other end of the connecting rod 545 is fixed with the second support arm 544. A roller 547 is fitted on the second support arm 544. A pressure handle 548 is installed on the first support arm 543. The metal coil spring 546 is elastic, and the roller 547 can be disengaged from the label-feeding roller 53 by pressing the pressure handle 548.

[0035] As an optional embodiment, the label feeding device 5 is equipped with a fixed-length detection fiber optic device 58, which is used to detect the length of the label. The control display device 8 is electrically connected to the fixed-length detection fiber optic device 58, and the control display device 8 inputs a length command to the fixed-length detection fiber optic device 58 to monitor the length of the label. The fixed-length detection fiber optic device 58 performs detection according to the required length entered by the control display device 8. Then, when the input length threshold is reached, the label cutting device 6 cuts the label.

[0036] As an optional embodiment, the guide wheel assembly 4 is equipped with a monitoring device. The monitoring device is used to sense whether a label is present to start or stop the inkjet printer 3. When the labels are used up, the monitoring device 41 will pause the inkjet printer 3 if it detects that there are no labels, thus protecting the inkjet printer 3.

[0037] As an optional embodiment, the label cutting device 6 includes a label feeding housing 61, a cylinder 62, and a cutter 63. The cylinder 62 is connected to the cutter 63. The cylinder 62 is fixed on the label feeding housing 61, and the cutter 63 is located inside the label feeding housing 61. The label feeding housing 61 is provided with a second through hole 611 through which the label passes. The cylinder 62 pushes the cutter to cut the label. This structure is simple and convenient.

[0038] In existing technologies, when adding material identification to packaging, some labels are pasted onto the mesh surface or the closure. However, these labels are prone to falling off and lack secure fastening. A new method is provided that allows the labels to be secured together at the closure of the mesh bag. A roll of labels is installed on the packing reel 1, and the labels are fed to the coding device 3 by the label guide wheel group 4 for coding. The coded labels are then straightened by the label feeding device 5 and placed into the closure device 7 to tie the mesh bag. After closure, the labels are cut by the label cutting device 6. This structure is less prone to falling off and allows for the recording of more material information on the labels.

[0039] The label loading tray 1 rotates and stops regularly under the action of its own self-adaptive elastic tension mechanism to ensure that the delivered labels can correctly reach each station, including the inkjet printing station, the label pressing and feeding station, the fixed-length detection fiber optic station, the cylinder cutting station, and the label tying station of the back-end equipment net bag packaging machine.

[0040] When the reel 1 is feeding material, the corresponding inkjet printing program can be adjusted by controlling the control display device 8, and then the control system will control the inkjet printing device 3 to perform real-time inkjet printing. When special information such as date or serial number is required, the control display device 8 provides the information, and the inkjet printing device 3 will also perform the corresponding processing to ensure that it meets the user's actual needs and customized functional requirements. On this basis, an external computer or remote signal interface can be used for remote control and real-time computer measurement and control processing.

[0041] Furthermore, manually printing on already packaged materials poses risks such as material damage or damage to the outer packaging due to secondary pushing or manual printing. This manual printing process places a heavy burden on workers. Moreover, worker fatigue can lead to errors and unpredictable defective products. This dedicated inkjet printing and labeling device for mesh bag packaging machines effectively addresses these uncertainties. Using this device improves product quality and allows for better operation of the sealing machine. In the food packaging industry, excessive reliance on manual labor is undesirable, and the emergence of aseptic product requirements necessitates suitable machinery. The continuous packaging process demands reduced manual intervention, making dedicated inkjet printing and labeling devices particularly important. This dedicated device for mesh bag packaging machines offers powerful functionality: real-time printing of labels, ensuring timely supply of the required labels to the mesh bag packaging machine.

[0042] The above embodiments are preferred embodiments of the present invention, but the embodiments of the present invention are not limited thereto. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present invention are equivalent substitutions and are included within the protection scope of the present invention.
