Description

TECHNICAL FIELD

[0001] The present application relates to a kind of packaging machinery, specifically relates to a kind of labeler for packaging material. BACKGROUND

[0002] The labeler is a kind of machine for packaging material with tax label. There are many tax labelers with different labeling methods on the market, but the structure of these machines is relatively complex, the action is not stable, and there are some technical problems. Traditional tax labeler usually uses mechanical structure to realize labeling function. These machines usually include conveyor belt, labeling head, control system and other components. During operation, packaging material is conveyed to the labeling position by the conveyor belt, and then the labeling head will perform the labeling action to paste the tax label on the packaging material. However, due to the complexity of mechanical structure, these machines have some problems in the labeling process. First of all, due to the complexity of mechanical structure, the maintenance and adjustment of tax labeler is relatively difficult. The precision and stability of mechanical parts are crucial for the normal operation of the machine, but due to the complex structure, maintenance personnel need to spend more time and effort to maintain and adjust. Secondly, the action of traditional tax labeler is not stable. In the labeling process, the action of the labeling head needs to be accurately positioned and executed to ensure that the tax label can be accurately pasted on the packaging material. However, due to the limitations of mechanical structure and the design problems of labeling head, the machine may have jitter or deviation during action execution, resulting in a decrease in the accuracy of tax label pasting.

[0018] As Figure 1As shown, the tax ticket labeling machine comprises a frame 1, a label material bin 3, a material conveying mechanism 2 and a labeling mechanism 4. The packaging object A is conveyed by the material conveying mechanism 2, and then the labeling mechanism 4 labels the tax ticket label B on a corner of the packaging object A, as shown. Figure 7 As shown.

[0019] As shown, Figure 3 The labeling mechanism 4 comprises a labeling suction nozzle 40 connected to a rotating rod 41, the rotating rod 41 is rotatably installed on a labeling slide 42, the frame 1 is provided with a vertical guide rail, the labeling slide 42 is slidingly arranged on the vertical guide rail, and the labeling slide 42 is drivingly connected with a power source 6 for driving the labeling slide 42 to move up and down; as shown, Figure 2 and Figure 4 The rotating rod 41 is connected with a gear 44 and a limiting block 43, the frame 1 is provided with a vertical guide rod 47, the vertical guide rod 47 is installed with a lifting slide 46, the upper portion of the lifting slide 46 is provided with an upper spring 48, the upper spring 48 acts on the upper end of the lifting slide 46, the lower portion of the lifting slide 46 is provided with a lower spring 49, the lower spring 49 acts on the lower end of the lifting slide 46; the lifting slide 46 is installed with a rack 45, the rack 45 is engaged with the gear 44, and the lifting slide 46 can limit the limiting block 43 to turn to one side; the label material bin 3 is located directly above the labeling suction nozzle 40.

[0020] The working principle of the labeling mechanism 4 is as follows: as shown, Figure 3 and Figure 4 When the power source 6 drives the labeling slide 42 to move upward, the rotating rod 41, the gear 44 and the limiting block 43 move upward synchronously, since the gear 44 is engaged with the rack 45, the gear 44 rotates, since the gear 44 is connected to the rotating rod 41, the rotating rod 41 rotates while moving upward, so that the labeling suction nozzle 40 on the rotating rod 41 gradually rotates upward (as shown, Figure 6The movement trajectory diagram), when the labeling slide 42 is moved to a certain position, the lifting slider 46 limits the limit block 43 to turn to one side, and because of the limitation, the rotating rod 41 and the gear 44 cannot rotate, so that the gear 44 gives the rack 45 an upward force, the rack 45 moves upward together with the lifting slider 46 following the gear 44, and the lifting slider 46 compresses the upper spring 48, in this process, the labeling suction nozzle 40 moves a certain distance linearly upward in a straight upward position (if it does not move in this way, it is difficult for the labeling suction nozzle 40 to suck the label B vertically), so that the labeling suction nozzle 40 can suck and adhere to the label B located directly above in a straight upward position, thereby stably adhering to the label B; after the label B is adhered, the power source 6 drives the labeling slide 42 to move downward, the gear 44 moves downward synchronously with the limit block 43, at the same time, the upper spring 48 drives the lifting slider 46 to move downward to reset, and the gear 44 reverses to drive the rotating rod 41 to rotate, so that the labeling suction nozzle 40 on the rotating rod 41 sucks the label B and gradually rotates downward (as shown in the movement trajectory diagram), when the labeling slide 42 is moved to a certain position, the lifting slider 46 limits the limit block 43 to turn to one side, and because of the limitation, the rotating rod 41 and the gear 44 cannot rotate, so that the gear 44 gives the rack 45 a downward force, the rack 45 moves downward together with the lifting slider 46 following the gear 44, and the lifting slider 46 compresses the lower spring 49, in this process, the labeling suction nozzle 40 moves a certain distance linearly downward in a straight downward position (if it does not move in this way, it is difficult for the labeling suction nozzle 40 to align the packaging object A vertically), so that the labeling suction nozzle 40 can paste the label B on the packaging object A in a straight downward position, thereby enabling the label B to be flatly pasted on the packaging object A. Figure 6 The movement trajectory diagram), when the labeling slide 42 is moved to a certain position, the lifting slider 46 limits the limit block 43 to turn to one side, and because of the limitation, the rotating rod 41 and the gear 44 cannot rotate, so that the gear 44 gives the rack 45 an upward force, the rack 45 moves upward together with the lifting slider 46 following the gear 44, and the lifting slider 46 compresses the upper spring 48, in this process, the labeling suction nozzle 40 moves a certain distance linearly upward in a straight upward position (if it does not move in this way, it is difficult for the labeling suction nozzle 40 to suck the label B vertically), so that the labeling suction nozzle 40 can suck and adhere to the label B located directly above in a straight upward position, thereby stably adhering to the label B; after the label B is adhered, the power source 6 drives the labeling slide 42 to move downward, the gear 44 moves downward synchronously with the limit block 43, at the same time, the upper spring 48 drives the lifting slider 46 to move downward to reset, and the gear 44 reverses to drive the rotating rod 41 to rotate, so that the labeling suction nozzle 40 on the rotating rod 41 sucks the label B and gradually rotates downward (as shown in the movement trajectory diagram), when the labeling slide 42 is moved to a certain position, the lifting slider 46 limits the limit block 43 to turn to one side, and because of the limitation, the rotating rod 41 and the gear 44 cannot rotate, so that the gear 44 gives the rack 45 a downward force, the rack 45 moves downward together with the lifting slider 46 following the gear 44, and the lifting slider 46 compresses the lower spring 49, in this process, the labeling suction nozzle 40 moves a certain distance linearly downward in a straight downward position (if it does not move in this way, it is difficult for the labeling suction nozzle 40 to align the packaging object A vertically), so that the labeling suction nozzle 40 can paste the label B on the packaging object A in a straight downward position, thereby enabling the label B to be flatly pasted on the packaging object A.

[0021] The labeling mechanism 4 has reasonable structure, low cost, stable operation, stable labeling, and precise labeling. The labeling speed of the existing equipment can reach 50 packages per minute, and the labeling machine using the labeling mechanism 4 can reach 100 packages per minute, and the labeling efficiency is significantly improved.

[0022] As shown in Figure 7 When the label B is pasted on the box-shaped packaging object A, the other side of the label B also needs to be pressed and pasted on the side of the packaging object A (different packaging objects A have different pasting methods), therefore, the present application is provided with a label pressing mechanism 5 on one side of the labeling mechanism 4, as shown in Figure 5As shown, the label pressing mechanism 5 comprises a label pressing wheel 50, which is installed on a label pressing slide 51. A label pressing guide rail is installed on the frame 1, and the label pressing slide 51 is slidingly arranged on the label pressing guide rail. The label pressing slide 51 is drivingly connected with a power source for driving the label pressing slide 51 to move up and down. Through the driving of the power source, the label pressing slide 51 is raised and lowered on the label pressing guide rail, thereby driving the label pressing wheel 50 to move up and down. The label pressing wheel 50 presses the other side of the label B onto the side of the packaging object A.

[0023] In order to drive the label pressing slide 51 to move, the transmission shaft 7 is drivingly connected with a label pressing transmission wheel 11 (through gear and chain transmission), and the label pressing transmission wheel 11 is hingedly connected with one end of a label pressing pull rod 13, and the other end of the label pressing pull rod 13 is hingedly connected with the label pressing slide 51. When the power source 6 drives the transmission shaft 7 to rotate, the transmission shaft 7 can drive the label pressing transmission wheel 11 to rotate, and the label pressing transmission wheel 11 can drive the label pressing pull rod 13 to drive the label pressing slide 51 to move up and down. Figure 2

[0024] Similarly, in order to drive the label pressing slide 51 to move, the transmission shaft 7 is drivingly connected with a label pressing transmission wheel 11 (through gear and chain transmission), and the label pressing transmission wheel 11 is hingedly connected with one end of a label pressing pull rod 13, and the other end of the label pressing pull rod 13 is hingedly connected with the label pressing slide 51. When the power source 6 drives the transmission shaft 7 to rotate, the transmission shaft 7 can drive the label pressing transmission wheel 11 to rotate, and the label pressing transmission wheel 11 can drive the label pressing pull rod 13 to drive the label pressing slide 51 to move up and down.

[0025] Through the transmission structure, the label pressing action and the label pressing action can be realized by one power source.

[0026] In order to drive the material conveying mechanism 2 to operate, the transmission shaft 7 is drivingly connected with an input end of a cam divider 8, and the material conveying mechanism 2 comprises a conveying belt and a conveying belt wheel 20. An output end of the cam divider 8 is drivingly connected with the conveying belt wheel 20 of the material conveying mechanism 2. The power source 6 drives the transmission shaft 7 to rotate, and through the action of the cam divider 8, the conveying belt of the material conveying mechanism 2 can realize intermittent conveying, that is, the conveying belt can be temporarily stopped, and the packaging object A can be temporarily stopped, thereby facilitating the labeling.

[0027] Through the above transmission structure, not only the labeling action and the label pressing action can be realized by one power source, but also the intermittent conveying of the material conveying mechanism 2 can be realized. In this way, the production cost can be greatly reduced, and the synchronization of the actions of the various mechanisms can be improved.

[0028] ​Finally, it is worth mentioning that the present application is also installed on the transmission shaft 7 encoder, the encoder is electrically connected with the controller, and the controller controls the glue spraying mechanism work. Through the encoder, the angle information of the transmission shaft 7 rotation can be obtained, the encoder transmits the signal to the controller, and the controller can control when the glue spraying mechanism sprays glue.
