[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention in any way.

[0017] See attached Figure 1 , 2As shown, the non-stop label changing mechanism of an AM label double labeling machine described in the utility model is arranged at the labeling station of the product assembly line body 1, and includes two labeling machine units arranged side by side, and the labeling machine unit includes a fixed box beam 5, a labeling machine fixed support plate 3, a linear slide rail 4 and an AM labeling machine 2. The fixed box beam 5 is fixed below the product assembly line body 1 to provide an installation position and support for the upper device of the entire labeling machine unit. The labeling machine fixed support plate 3 is slidably arranged on the upper surface of the fixed box beam 5 through the linear slide rail 4, and the sliding direction is perpendicular to the conveying direction of the product assembly line body 1. The AM labeling machine 2 is fixedly installed at one end of the labeling machine fixed support plate 3. During the linear sliding process of the labeling machine fixed support plate 3, the AM labeling machine 2 approaches or moves away from the product assembly line body 1. After the AM labeling machine 2 moves toward the product assembly line 1 and moves into position, the product materials conveyed on the product assembly line 1 can be labeled; after the AM labeling machine 2 moves away from the product assembly line 1 and moves into position, the label roll can be replaced. By using the two labeling machine units alternately, the label roll can be replaced without stopping the line, ensuring the normal production rhythm, and improving the utilization rate of the equipment and the product output.

[0018] In order to ensure the accurate positioning of the AM labeling machine 2 after it moves, and avoid the situation that it cannot be labeled due to not moving into position or offside, a drag-in position positioning point 7 and a drag-out position positioning point 6 are also provided on the fixed support plate 3 of the labeling machine, wherein the drag-in position positioning point 7 is used to indicate the accurate position of the AM labeling machine 2 when labeling, and the drag-out position positioning point 6 is used to indicate the accurate position of the AM labeling machine 2 when changing the label roll. Below the product assembly line body 1, a bracket is also provided between the two labeling machine units, and the bracket has a cantilever extending toward the two labeling machine units, and the lower surface of each cantilever is provided with a pneumatic pin assembly 8, and the pneumatic components in the pneumatic pin assembly 8 control the pin to extend and retract up and down. When the drag-in position positioning point 7 or the drag-out position positioning point 6 reaches the bottom of the pneumatic pin assembly 8, the pin extends downward and is inserted into the positioning hole of the drag-in position positioning point 7 or the drag-out position positioning point 6, so as to fix the position of the AM labeling machine 2 and avoid the position deviation of the AM labeling machine 2 during the labeling process or the label roll replacement process.

[0019] As an alternative, the pneumatic pin assembly 8 can also be arranged on the frame of the product assembly line body 1. The pneumatic pin assembly 8 can also be replaced by other forms of telescopic mechanisms, such as a cylinder, an oil cylinder or an electric push rod, and the movable part of the telescopic mechanism is connected to the drag-in position positioning point 7 or the drag-out position positioning point 6.

[0020] In order to further ensure the reliable positioning of the AM labeling machine 2 during the labeling process, in addition to the cooperation of the pneumatic pin assembly 8 and the drag-in-place positioning point 7, a gas expansion shaft assembly 9 can also be provided on the side of the frame of the product assembly line body 1, and a labeling machine positioning lug 10 is correspondingly provided on the AM labeling machine 2, and a fixing hole that cooperates with the gas expansion shaft is provided on the labeling machine positioning lug 10. When the AM labeling machine 2 is pushed in, the pneumatic pin assembly 8 and the drag-in-place positioning point 7 are matched and connected, and the gas expansion shaft of the gas expansion shaft assembly 9 is inserted into the fixing hole on the labeling machine positioning lug 10, and the AM labeling machine 2 is locked after ventilation.

[0021] Furthermore, each AM labeling machine 2 is provided with two labeling machine positioning ears 10, and two air expansion shaft assemblies 9 are provided in coordination therewith, so that the AM labeling machine 2 is fixed more reliably.

[0022] In order to facilitate dragging of the labeling machine unit, a handle for manual dragging is also provided on the labeling machine fixed support plate 3 or the AM labeling machine 2 of each labeling machine unit.

[0023] The working process of the utility model is as follows: products are continuously flowing out of the product assembly line, one AM labeling machine 2 labels the products, and the other is in the labeling position at this time, that is, the dragged-in positioning point 7 is connected to the pneumatic pin assembly 8, and the labeling machine positioning ear 10 is connected to the pneumatic shaft assembly 9, but the labeling machine does not start the labeling action. When the label roll of the AM labeling machine 2 that performs the labeling action is used up, start another AM labeling machine 2 to perform the labeling action; loosen the connection between the AM labeling machine 2 that needs to replace the label roll and the air expansion shaft assembly 9, and the connection between the corresponding labeling machine fixed support plate 3 and the pneumatic pin assembly 8, drag the AM labeling machine 2 out to the drag-out positioning point 6 and align it with the pneumatic pin assembly 8, and then the pneumatic pin assembly 8 locks the labeling machine fixed support plate 3, and then the label roll on the labeling machine can be replaced; after installing the new label roll, push the labeling machine fixed support plate 3 of the AM labeling machine 2 that has replaced the label roll again to the drag-in positioning point 7 and align it with the corresponding pneumatic pin assembly 8, and the pneumatic pin assembly 8 locks the labeling machine fixed support plate 3, and at the same time, the air expansion shaft assembly 9 is fixedly connected to the labeling machine positioning ear 10, and the label roll replacement operation is completed. When the label roll in the running AM labeling machine is used up, repeat the above label roll replacement operation to realize the non-stop labeling operation of the AM labeling machine.

[0024] The above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Ordinary technicians in the relevant field should understand that the specific implementation methods of the present invention can be modified or replaced by equivalents with reference to the above embodiments. Any modifications or equivalent replacements that do not depart from the spirit and scope of the present invention are within the scope of protection of the pending claims.
