[0020] The following further describes the utility model with reference to the drawings.

[0021] As Figure 1As shown in the figure, an automated bag sealing and labeling system includes a bag sealing device 2, a folding device 3, and a labeling device 4 provided on a paper bag conveying device 1; the bag sealing device 2 is composed of a paper bag side tightening mechanism 2.1 for tightening both sides of the paper bag and a paper bag mouth clamping mechanism 2.2 for clamping the paper bag mouth once; the folding device 3 realizes secondary clamping of the paper bag mouth through the opening and closing of a cylinder jaw 33; the labeling device 4 includes a label tape transmission mechanism 4.1, a label tape tensioning mechanism 4.2, a label peeling mechanism 4.3, and a label fitting mechanism 4.4. The utility model integrates three production processes of bag sealing, folding, and labeling into the same food packaging production line for bagging, thereby realizing low-cost and high-efficiency bag sealing and labeling operations and improving the economy, safety, and efficiency of food packaging.

[0022] As Figure 2 shown, the present utility model includes a linear movement mechanism 5 corresponding to the bag sealing device 2. The linear movement mechanism 5 is parallel to the paper bag conveying device 1, and the linear movement mechanism 5 drives the bag sealing device 2 to linearly move along the length direction of the paper bag conveying device 1. The linear movement mechanism 5 is preferably driven by a belt pulley through the rotation of a motor, and then drives a lead screw to rotate to make a slider move in a guide rail, thereby driving the bag sealing device 2 to linearly move. In addition, the paper bag conveying device 1 in the present utility model is preferably a belt conveyor.

[0023] The paper bag side tightening mechanism 2.1 is a swing guide bar mechanism for clamping both sides of the paper bag. Its principle is: through the rotation of the swing guide bar mechanism, both sides of the paper bag are tightened to facilitate subsequent clamping of the paper bag mouth. More specifically, as Figure 3 shown, the paper bag side tightening mechanism 2.1 includes a fixed frame 23, a rotating rod 24, and a swing rod 25. The rotating rod 24 and the swing rod 25 are respectively rotatably connected to the fixed frame 23, and the swing rod 25 is provided with a sleeve, and the rotating rod 24 is rotatably connected to the sleeve.

[0024] As Figure 4 shown, the paper bag mouth clamping mechanism 2.2 includes a rotating rod 20, a two-force bar 21, and a guide bar 22. The upper and lower ends of an intermediate rotating rod 20 are respectively connected to the guide bar 22 through the two-force bar 21 to form a staggered link mechanism. Clamping suction cups 2.3 are respectively arranged at the same-side ends of the upper and lower guide bars 22. Through the rotation of the rotating rod 20, the staggered movement of the upper and lower guide bars 22 is driven, and the two-force bar 21 can play the connection effect of an extension arm, thereby clamping and sealing the paper bag.

[0025] As Figure 5As shown in the figure, the folding device 3 further includes a rack 30, a gear 31, and a jaw cylinder 32; the gear 31 meshes with the rack 30, and the jaw cylinder 32 equipped with a cylinder jaw 33 is connected to the gear 31; the linear movement of the rack 30 drives the gear 31, the jaw cylinder 32, and the cylinder jaw 33 to rotate synchronously; the jaw cylinder 32 drives the cylinder jaw 33 to open and close to clamp the paper bag mouth. The linear movement of the rack 30 drives the rotation of the gear 31, thereby realizing the rotation of the cylinder jaw 33. Furthermore, under the drive of the jaw cylinder 32, the cylinder jaw 33 is driven to open and close, thereby realizing the secondary clamping of the paper bag mouth.

[0026] As Figure 6 shown in the figure, the label tape transmission mechanism 4.1 consists of a pair of rotating wheels 40 connected by a belt drive. This pair of rotating wheels 40 drives the label tape to transmit through rotational friction. In order to increase the friction force, grooves can be opened on the rotating wheels 40. One of the leading ends of the label tape is a label tape releasing wheel, and the trailing end of the label tape is a label tape winding wheel. The label tape tensioning mechanism 4.2 includes a tensioning wheel 41 and a tape pressing member 42 arranged in sequence on the movement path of the label tape transmission. The label tape realizes the tension adjustment of the tape body through the guiding of the tensioning wheel 41 and the tape pressing of the tape pressing member 42. The tape pressing member 42 includes a tape pressing structure 47 driven by a tape pressing cylinder 48. The tape pressing structure 47 presses on the label tape. By driving the height adjustment of the tape pressing structure 47 through the tape pressing cylinder 48, the tension adjustment of the label tape can be adjusted. Some flexible structural materials, such as bristles, can be arranged on the tape pressing surface of the tape pressing structure 47 to avoid damaging the label tape. The label peeling mechanism 4.3 is located between the tensioning wheel 41 and the tape pressing member 42. The label peeling mechanism 4.3 includes a peeling disc 43 with a peeling tip 43a. When the label tape passes through the peeling disc 43 in a tensioned transmission state, the label is peeled off through the relative extrusion effect of the peeling tip 43a. The label pasting mechanism 4.4 consists of a turntable 44, a telescopic member 45, and a label suction cup 46 connected in sequence. The turntable 44 is driven to rotate by a stepping motor. The telescopic member 45 can be selected as a telescopic cylinder installed on the turntable 44. The telescopic end of the telescopic cylinder is connected to the label suction cup 46. The rotation of the turntable 44 drives the telescopic cylinder to rotate. The label is sucked by driving the movement of the label suction cup 46 through the telescopic cylinder, and then labeling is carried out.

[0027] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
