[0002] E-commerce business has seen explosive growth, and massive orders have led to a huge demand for commodity carton packaging. E-commerce shopping focuses on customer experience and has extremely high requirements for package delivery speed and the appearance and accuracy of packaging labels. The rapid and accurate pasting of waybill labels, product identification labels, etc. has become a key link in improving logistics efficiency and ensuring customer satisfaction.

[0003] When using traditional label pasting equipment, workers are required to constantly straighten the cartons being conveyed. Dust may adhere to the cartons, causing the labels to not be firmly pasted. At the same time, after pasting, the labels need to be squeezed through a plate to be compacted. This method is very harmful to the cartons and has low efficiency.

The purpose is to achieve the purpose of solving problems and improving practical value through this technology. Summary of the invention

[0005] The present invention cleans the cartons during transportation, and at the same time, drives the positioning block to straighten the carton through a reciprocating screw. When the positioning block moves, the airbag is inflated through a push rod. When the airbag expands, it squeezes the labeled carton, thereby compacting the label to make it more firmly fitted. At the same time, the airbag is made of soft material, which avoids damage to the carton caused by squeezing during the compaction process, thereby realizing a carton surface label sticking device.

[0018] In an optional embodiment: the conveyor belt 2 is fixed by being connected to the inner wall of the fixed plate 1, a rotating shaft is provided at the output end of the conveyor belt 2, and the rotating shaft is connected to the motor 3, one end of the conveyor belt 2 is fixedly connected to a discharge trough 4, and the discharge trough 4 is fixed by being connected to the fixed plate 1, and the lower end of the discharge trough 4 close to the conveyor belt 2 is hollow, when in use, the staff places the carton inside 4, so that 2 will gradually transport the carton through the drive of 3, thereby reducing the labor intensity of the staff, and also avoiding the reduction of work efficiency by placing them one by one.

[0019] In an optional embodiment: pulley A5 is fixedly connected to the outside of the rotating shaft, and rotates by rotating the rotating shaft. Pulley B7 rotates by driving belt 6 through pulley A5, and the size of pulley B7 is smaller than pulley A5. Connecting shaft 8 is fixedly connected to one end of pulley B7. Two groups of connecting blocks 10 are arranged at both ends of connecting shaft 8. Both groups of connecting blocks 10 are fixedly connected to fixed plate 1. Cleaning roller 11 is connected to connecting block 10 through connecting shaft 8 for fixation. When motor 3 drives conveyor belt 2 to rotate, it will drive pulley A5 to rotate synchronously. When pulley A5 rotates, it will drive pulley B7 to rotate synchronously through belt 6. At the same time, because pulley A5 is larger than pulley B7, the frequency of rotation of pulley B7 is greater than that of pulley A5. At the same time, when pulley B7 rotates, it will drive cleaning roller 11 to rotate synchronously, so as to clean the carton before labeling to prevent surface dust from causing the label to be unable to fit with it.

[0020] In an optional embodiment: the reciprocating screw 9 is located between the connecting block 10 and the cleaning roller 11, and the reciprocating screw 9 is arranged at both ends of the cleaning roller 11, and the positioning blocks 12 are arranged on the outside of the reciprocating screw 9 at both ends, which are connected to the ball nut pair of the reciprocating screw 9, and the push rod 13 is fixedly connected to the side of the positioning block 12 close to the outer end. It is movably connected inside the air pressure chamber 14, and the air pressure chamber 14 extends to the outer end through the fixed plate 1. When the pulley B7 drives the cleaning roller 11 to rotate through the connecting shaft 8, since the reciprocating screw 9 is fixedly connected to the connecting shaft 8, when the connecting shaft 8 rotates, it will drive the reciprocating screw 9 to rotate synchronously, so that the reciprocating screw 9 will drive the positioning block 12 to reciprocate inward when rotating, so as to straighten the carton during transportation, and prevent the carton from shifting during transportation, resulting in subsequent labeling being skewed, so as to position the carton while cleaning the surface of the carton, and at the same time, when the positioning block 12 reciprocates, it will drive the push rod 13 to move synchronously inside the air pressure chamber 14, so as to continuously inflate the inside of the air pressure chamber 14, and while inflating the inside of the air pressure chamber 14, the air pressure chamber 14 will continuously input air into the airbag 21 through the connecting pipe 15, so as to expand the airbag 21.

[0021] In an optional embodiment: the connecting tube 15 is connected to the outer end of the air pressure chamber 14, and extends to the rear end to be connected to the airbag 21. The rear end of the cleaning roller 11 is fixedly connected to a guide frame 16 for stretching, and a plurality of connecting rods are arranged inside the guide frame 16. Since the label will bend when it is pulled out after being rolled up, it is stretched by the plurality of connecting rods inside the guide frame 16 to prevent the label from bending and causing poor adhesion.

[0022] In an optional embodiment: a connecting rod 17 is provided at the rear end of the guide frame 16, and the connecting rod 17 is fixedly connected to the fixed plate 1, and the outer side of the connecting rod 17 is movably connected to the loading roller 18, and the loading roller 18 is fixed to the outer side of the connecting rod 17 by a buckle 19, and a reciprocating screw rod 9 is provided at both ends of the loading roller 18, and there are two groups of reciprocating screws 9, and the loading roller 18 is fixed by two groups of buckles 19 to prevent the label from breaking due to deviation during rotation.

[0023] In an optional embodiment: a fixing frame 20 for fixing is fixedly connected to the end of the fixing plate 1, and an airbag 21 is fixedly connected to the lower end of the fixing frame 20. The connecting pipe 15 passes through the upper end of the fixing frame 20 and is connected to the airbag 21. A pressure relief valve 22 for pressure relief is fixedly connected to one side of the airbag 21. When the airbag 21 expands, it will squeeze the labeled carton, thereby compacting the label to make it more firmly fitted. At the same time, the airbag 21 is made of soft material, which avoids damage to the carton caused by squeezing during the compaction process. At the same time, the pressure relief valve 22 will open when the air pressure inside the airbag 21 reaches a certain value, thereby relieving the pressure inside the airbag 21 to prevent the airbag 21 from rupturing due to excessive air pressure.

[0024] Working principle and process: The staff places the carton inside the discharge trough 4 and starts the equipment. At this time, the motor 3 will drive the conveyor belt 2 to transport the carton. While the motor 3 is driving, it will drive the pulley A5 to rotate synchronously, so that the pulley A5 drives the pulley B7 to rotate synchronously through the belt 6. When the pulley B7 rotates, it will drive the cleaning roller 11 to rotate synchronously through the connecting shaft 8 to clean the carton. At the same time, the connecting shaft 8 will drive the reciprocating screw 9 to rotate when it rotates. When the reciprocating screw 9 rotates, it will drive the positioning block 12 to move back and forth, so as to straighten the carton. At the same time, when the positioning block 12 moves, the push rod 13 will continuously inflate the inside of the airbag 21, so as to compact the label. When the air pressure inside the airbag 21 reaches a certain value, it will be released through the pressure relief valve 22.
