Description

Technical Field

[0001] The utility model relates to the technical field of packaging carton production equipment, in particular to a carton bubble pressing machine. Background Technique

[0002] The function of the bubble pressing machine in the production of packaging cartons is to solve problems such as air bubbles, bulges, wrinkles, and deformations on the bonding surface after the cartons are manufactured and formed, and to achieve excellent characteristics and precision through a flattening and correcting device. It mainly applies pressure pneumatically to quickly smooth the air bubbles on the packaging carton, making the corners of the packaging carton coordinated, thus greatly reducing the damage rate of manual operation and improving work efficiency at the same time.

[0003] After retrieval, the patent document with the publication number: CN216579410U discloses a bubble pressing machine for a packaging box production line. It is convenient to replace the pressing block by setting a rotating ring and a rack. When pressing bubbles for cartons of different sizes, first replace the side plate and the bottom plate, and then rotate the rotating ring. At this time, the rotating ring drives the gear to rotate, and the gear drives the rack to slide, so that the end of the rack is no longer engaged with the card slot, and the pressing block is pulled out downward. Then, the connecting groove of the new pressing block is engaged with the connecting block, and then the rotating ring is rotated. At this time, the end of the rack is engaged with the card slot, and the installation of the pressing block is completed. The utility model can conveniently replace the pressing block, has high positioning accuracy and good bubble pressing quality. It is convenient to take out the carton by setting a strip-shaped groove and an airbag. After the carton is bubble-pressed, the airbag expands at this time, and the airbag jacks up the carton, so that the carton can be conveniently taken out, improving the bubble pressing efficiency.

[0004] When the above-mentioned bubble pressing machine is actually used, it is necessary to manually place the packaging carton on the bottom plate and then manually take it out by the ejection method. During the manual placement and taking-out process, when producing a large number of packaging cartons, continuous feeding is required, resulting in high labor intensity and insufficient stability. In the case where the packaging carton is not aligned, it is easy to be damaged during subsequent bubble pressing. Content of the Utility Model

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0022] By Figures 1 - 3As shown in the figure, it relates to a carton bubble pressing machine, which includes a bubble pressing machine body 1. An L-shaped frame is fixedly connected to the top of the bubble pressing machine body 1. A machine frame 2 is fixedly connected to the outer wall of the L-shaped frame. A servo motor 3 is fixedly connected to the inside of the machine frame 2. A sliding hole is opened at the bottom of the machine frame 2. The inner wall of the sliding hole is rotationally connected to the outer wall of the output shaft of the servo motor 3. A connecting shaft 4 is fixedly connected to the bottom of the output shaft of the servo motor 3. A machine frame 5 is fixedly connected to the bottom of the connecting shaft 4. The operation of the servo motor 3 drives the connecting shaft 4 and the machine frame 5 to rotate, and the angular displacement and angular velocity of the output shaft of the servo motor 3 are controlled by an existing encoder.

[0023] A conveying frame 10 is fixedly connected to the outer wall of the bubble pressing machine body 1. Four L-shaped legs are fixedly connected to the bottom of the conveying frame 10. A circular frame 11 is fixedly connected to the outer wall of the conveying frame 10. A DC motor 12 is fixedly connected to the inside of the circular frame 11. A through hole is opened on the outer wall of the conveying frame 10. The inner wall of the through hole is rotationally connected to the outer wall of the output shaft of the DC motor 12.

[0024] Two driving rollers 13 are rotationally connected to the inside of the conveying frame 10. One end of the output shaft of the DC motor 12 is rotationally connected to the outer wall of one of the driving rollers 13. The same rubber conveyor belt 14 is sleeved on the outer walls of the two driving rollers 13. There is friction and extrusion force between the two driving rollers 13 and the rubber conveyor belt 14, so that they rotate synchronously.

[0025] A taking mechanism is arranged on the outer wall of the machine frame 5. The taking mechanism includes two cylinders 7. A vacuum pump 6 is fixedly connected to the top of the machine frame 5. The outer walls of the two cylinders 7 are fixedly connected to the bottom of the machine frame 5. The bottom of the output ends of the two cylinders 7 are fixedly connected with air extraction discs 8 with a hollow structure. The operation of the vacuum pump 6 makes the inside of the air extraction disc 8 in a negative pressure state.

[0026] A plurality of vacuum suction nozzles 9 are fixedly communicated with the bottom of the air extraction disc 8. Two connecting pipes are fixedly communicated with the input end of the vacuum pump 6. One end of each of the two connecting pipes is fixedly communicated with the outer wall of one of the two air extraction discs 8. Existing solenoid valves are fixedly installed on the outer walls of the two connecting pipes.

[0027] A limiting mechanism is fixedly connected to the inside of the conveying frame 10. The limiting mechanism includes a baffle 15. The inner wall of the conveying frame 10 is fixedly connected to the outer wall of the baffle 15. The baffle 15 is located in the middle of the conveying frame 10 and its bottom does not contact the rubber conveyor belt 14. Two strip-shaped holes 16 are opened on the outer wall of the baffle 15. Two guide rods 17 are slidably connected to the inner walls of the two strip-shaped holes 16. Two nuts 18 are threadedly sleeved on the outer walls of the guide rods 17. The outer walls of the two nuts 18 are pressed against the outer wall of the baffle 15. Rotating the four nuts 18 can release the position fixation of the two guide rods 17. The guide rods 17 slide in the strip-shaped holes 16 to adjust the relative distance between the two guide rods 17, which is convenient for guiding cartons of different sizes.

[0028] Working principle: When in use, multiple paper boxes are placed on the rubber conveyor belt 14. As the DC motor 12 operates, it drives one of the transmission rollers 13 to rotate. Through the rubber conveyor belt 14, the other transmission roller 13 is driven to rotate, thereby driving the paper box to move backward. And the two guide rods 17 assist the paper box to move linearly. After moving to the position of the baffle 15, the baffle 15 blocks the paper box. Then, the cylinder 7 located above the paper box operates to drive the air extraction disc 8 and multiple vacuum suction nozzles 9 to move downward. The vacuum pump 6 operates to generate suction, and through the connecting pipe, a negative pressure is generated inside the air extraction disc 8 and multiple vacuum suction nozzles 9, sucking the paper box from the top. The servo motor 3 operates to drive the connecting shaft 4 and the frame 5 to rotate. After the frame 5 rotates 180 degrees, the cylinder 7 operates to drive the paper box to move downward and fall onto the top of the upper base plate of the bubble pressing machine body 1. The solenoid valve operates to make the connecting pipe communicate with the outside. After inhaling the outside air, no negative pressure can be generated inside the vacuum suction nozzle 9, releasing the adsorption of the paper box. The servo motor 3 operates to drive the frame 5 to rotate. The cylinder 7 is not located inside the bubble pressing machine body 1. The bubble pressing machine body 1 starts to operate to perform the bubble removal operation on the paper box. After completion, as the frame 5 rotates and returns to its original position, the vacuum pump 6 and the two cylinders 7 operate to exchange the bubble-removed paper box with the paper box on the rubber conveyor belt 14, forming a new round of bubble removal operation. At the same time, when the bubble-removed paper box is at the top of the rubber conveyor belt 14 behind the baffle 15, the solenoid valve is opened to allow the corresponding connecting pipe to intake air, and the multiple vacuum suction nozzles 9 release the adsorption of the paper box. The bubble-removed paper box falls onto the rubber conveyor belt 14 and is conveyed backward.
