Description

Technical Field

[0001] This invention relates to the field of egg carton packaging equipment technology, and in particular to a high-efficiency egg carton adhesive spraying and labeling machine. Background Technology

[0002] Egg cartons are specialized containers used for packaging and transporting poultry eggs (such as chicken eggs, duck eggs, and quail eggs). Their primary function is to protect eggs from damage and contamination and to facilitate storage and sales. During production, the surface of the egg cartons first undergoes adhesive spraying and labeling. Following this, the cartons are pressed and shaped to ensure the label adheres to the carton. Finally, the finished egg cartons are picked up and stacked by workers. Some steps in the egg carton labeling process, such as stacking, require manual operation and movement to different equipment, resulting in low production efficiency. Therefore, an integrated egg carton labeling machine structure needs to be designed to address these issues. Summary of the Invention

Detailed Implementation

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so as to provide a clearer understanding of the technical concept claimed by the present invention.

[0033] like Figures 1 to 16 As shown, a high-efficiency egg carton adhesive spraying and labeling machine includes a conveyor frame 1 and a feeding mechanism 2, an adhesive spraying mechanism 3, a labeling mechanism 4, a pressing mechanism 5, and a stacking mechanism 6 arranged sequentially along the egg carton conveying direction on the conveyor frame 1. The conveyor frame 1 is equipped with a conveyor 7 for conveying egg cartons. The feeding mechanism 2, labeling mechanism 4, and stacking mechanism 6 each include a frame 8, a lifting device, and a swinging robot. The frame 8 is equipped with multiple storage racks 9. The lifting device is located at the lower part of the frame 8, and its output end is connected to the swinging robot. The lifting device of the feeding mechanism 2 drives the swinging robot. The hand places multiple egg cartons from storage racks 9 onto conveyor 7. The glue spraying mechanism 3 includes a mounting frame 10 and a glue sprayer. The glue sprayer is mounted on the mounting frame 10 and performs glue spraying on the egg cartons on conveyor 7. The lifting mechanism 4 drives the swinging robot to take labels from multiple storage racks 9 and place them on the egg cartons on conveyor 7. The pressing mechanism 5 includes two pressing mechanisms 5, which are arranged vertically opposite each other and press the egg cartons and labels on conveyor 7. The lifting mechanism 6 drives the swinging robot to stack multiple egg cartons from conveyor 7 into storage racks 9.

[0034] The high-efficiency egg carton adhesive spraying and labeling machine of the present invention works by the cooperation of the feeding mechanism 2, the adhesive spraying mechanism 3, the labeling mechanism 4, the pressing mechanism 5, and the stacking mechanism 6. Figures 1 to 16As shown, the lifting mechanism 2 drives the swinging robot to place egg cartons from multiple storage racks 9 onto the conveyor 7. The egg cartons are then sequentially conveyed along the conveyor 7 to the glue spraying mechanism 3, labeling mechanism 4, pressing mechanism 5, and stacking mechanism 6. The glue sprayer of the glue spraying mechanism 3 is mounted on the mounting frame 10 and performs glue spraying on the egg cartons on the conveyor 7. The lifting mechanism 4 drives the swinging robot to take labels from multiple storage racks 9 and place them on the egg cartons on the conveyor 7, thus adhering the labels to the egg cartons. The two pressing mechanisms 5 of the pressing mechanism 5 press the egg cartons and labels on the conveyor 7 and adhere the labels to the egg cartons. Finally, the lifting mechanism 6 drives the swinging robot to stack the multiple egg cartons from the conveyor 7 into the storage racks 9. Compared with traditional egg carton labeling devices, this high-efficiency egg carton glue spraying and labeling machine automatically completes the egg carton feeding, glue spraying, labeling, pressing, and stacking processes. The overall structure is more compact and integrated, and the packaging and processing efficiency of egg cartons is improved.

[0035] Specifically, the conveyor 7 includes a conveyor wheel, a conveyor belt, and a first driver. The top surface of the conveyor frame 1 is provided with a bracket 11 for placing egg cartons. Multiple levers 12 are provided on the conveyor belt. The output end of the first driver is connected to the conveyor wheel, and the first driver drives the multiple levers 12 on the conveyor belt via the conveyor wheel to move the egg cartons on the bracket 11. Figures 1 to 16 As shown, the first driver drives the conveyor wheel to rotate, the conveyor wheel drives the conveyor belt and the lever 12 to move, and the lever 12 drives the egg carton to move along the support 11. The first driver can be a servo motor, which has the functions of metering and accurate positioning. The high-efficiency egg carton spraying and labeling machine can be equipped with a control host (not shown in the figure). The first driver is electrically connected to the control host so that the conveyor 7 can drive the egg carton to move sequentially to the spraying mechanism 3, the labeling mechanism 4, the pressing mechanism 5 and the stacking mechanism 6 for processing.

[0036] Further, the swinging manipulator includes a first swing arm 13, a second swing arm 14, and a crossbar 15. Mounting plates 16 are provided on the left and right sides of the frame 8. The first swing arm 13 has a through groove 17, and the mounting plate 16 has mounting posts 18. The through grooves 17 of the two first swing arms 13 are slidably connected to the mounting posts 18 of the two mounting plates 16, and the first swing arms 13 swing around the mounting posts 18. The two first swing arms 13 are connected by the crossbar 15. The middle portions of multiple second swing arms 14 are hinged to the frame 8 via pivots, and the ends of the multiple second swing arms 14 away from the egg carton storage rack 9 are hinged to the crossbar 15. The lifting device includes a second driver 19 and a drive disc. 20 and connecting rod 21, the output end of the second driver 19 is connected to the driving disk 20 and drives the driving disk 20 to rotate, the driving disk 20 is hinged to one end of the connecting rod 21, and the other end of the connecting rod 21 is connected to a second swing arm 14 located in the middle, wherein the feeding mechanism 2 also includes a plurality of first telescopic devices 22, a plurality of storage racks 9 of the feeding mechanism 2 are inclined downward toward the conveyor 7, a plurality of first telescopic devices 22 are arranged on the front and back of the storage racks 9, and the output end of the first telescopic device 22 is provided with a stop bar 23 that abuts against the egg box, the crossbar 15 of the feeding mechanism 2 is provided with a plurality of first support plates, and the bottom surface of the first support plates is provided with a plurality of first suction devices 24, such as Figures 1 to 16As shown, the second driver 19 can adopt a drive structure consisting of a servo motor, drive shaft, chain, and sprocket. The feeding mechanism 2, labeling mechanism 4, and stacking mechanism 6 can share a single drive shaft. This allows a servo motor to drive the drive shaft through the chain and sprocket drive structure. The drive shaft can also drive the connecting shaft of the drive disc 20 through the chain and sprocket drive structure, thus linking the drive disc 20 with the drive shaft. This is a conventional drive structure and will not be described in detail. The edge of the drive disc 20 is hinged to the connecting rod 21, allowing the drive disc 20 to swing and cause the second pendulum to swing. One end of arm 14 swings, and the storage rack 9 of the unloading mechanism 2 is tilted downward so that the egg cartons inside the storage rack 9 can abut against the baffle bar under their own weight. The first telescopic device 22 located on the front side of the storage rack 9 drives the baffle bar 23 to extend and block the first egg carton. The first telescopic device 22 located on the back side of the front side of the storage rack 9 drives the baffle bar 23 to extend and block the second egg carton. The first telescopic device 22 can be a telescopic cylinder. When the egg cartons are unloaded, the first suction device 24 of the unloading mechanism 2 suctions the first egg carton on the front side of the storage rack 9. The first suction device 24 can be a vacuum suction cup. Subsequently, the first suction device 24 located on the front side of the storage rack 9... The telescopic device 22 causes the stop bar 23 to separate from the first egg carton. The drive disc 20 drives the connecting rod 21 to swing, causing one end of the second swing arm 14 to swing upward and the other end to swing downward. The second swing arm 14 drives the first swing arm 13 to swing outward, and the first swing arm 13 slides along the mounting post 18 of the mounting plate 16 through the slide groove, so that the first swing arm 13 swings smoothly from a horizontal state to a vertical state. In this way, the first support plate swings from a vertical state to a horizontal state. The first suction device 24 releases the egg carton and places the egg carton on the bracket 11 of the conveyor frame 1 for conveying. Then, the drive disc 20 drives the first swing arm 13 and the second swing arm 14 to reset via the connecting rod 21. At the same time, the first egg box separates from the second egg box. The first telescopic device 22 located on the front side of the storage rack 9 drives the stop bar 23 to reset. The first telescopic device 22 located on the back side of the storage rack 9 drives the stop bar to separate from the second egg box. In this way, the second egg box moves down along the storage rack 9 under its own gravity and abuts against the stop bar 23 of the first telescopic device 22 located on the front side of the storage rack 9. Then, the first telescopic device 22 located on the back side of the storage rack 9 drives the stop bar 23 to reset. This cycle is repeated to unload the egg boxes.

[0037] Furthermore, the glue spraying mechanism 3 also includes a receiving tank 25, a cleaning tank 26, a third drive 27, a delivery pump 28, and a control valve 29. The conveyor frame 1 is equipped with a receiving tray 30 to hold dripping glue. The glue sprayer includes a slide 31 and multiple spray heads 32, with the multiple spray heads 32 mounted on the slide 31. The mounting frame 10 is fixed to the top surface of the conveyor frame 1, and the mounting frame 10 is equipped with a conveying structure consisting of pulleys and a belt. The slide 31 is connected to the belt, and the third drive 27... A conveyor structure using pulleys and belts drives the slide 31 to move along the mounting frame 10. The container 25 and the cleaning tank 26 are arranged adjacent to the conveyor frame 1. Multiple spray nozzles 32 are equipped with return pipes 33 for placing the container 25 or the cleaning tank 26. The multiple spray nozzles 32 are connected to the conveying pump 28 via input pipes. The conveying pump 28 is equipped with multiple conveying pipes 34 for placing the container 25 or the cleaning tank 26. Multiple control valves 29 are connected to the multiple spray nozzles 32 via connecting pipes. Figures 1 to 16 As shown, the third drive 27 can be a servo motor, which has metering and accurate positioning functions. The first drive is electrically connected to the control host of the high-efficiency egg carton glue spraying and labeling machine, so that the first drive drives the slide 31 and the glue spraying head 32 to move along the mounting frame 10, thereby adjusting the position of the glue spraying head 32 on the slide 31 as needed. The container 25 stores glue. The delivery pump 28 can be a diaphragm pump. The delivery pump 28 draws glue from the container 25 through the delivery pipe 34 and delivers it to the glue spraying head 32 through the input pipe. The glue in the glue spraying head 32 is delivered to the container 25 from the return pipe 33, thus forming a circulation of glue. When the egg carton is transported along the bracket 11 to the glue spraying mechanism 3 for glue spraying, the glue spraying head 32 can be equipped with a nozzle opening. The conventional nozzle structure with the shut-off and atomization switch is not described in detail. The control valve 29 controls the nozzle switch of the glue spray head 32 to open, and causes the glue spray head 32 to atomize and spray glue onto the surface of the egg carton. The control valve 29 can be a solenoid valve to control the operation of the nozzle switch and atomization switch on the glue spray head 32. After the glue spraying process on the egg carton, the operator can put the delivery pipe 34 and the return pipe 33 into the cleaning tank 26. The cleaning tank 26 stores cleaning water. The delivery pump 28 draws the cleaning water from the cleaning tank 26 through the delivery pipe 34 and delivers it to the glue spray head 32 through the input pipe. The cleaning water of the glue spray head 32 is delivered from the return pipe 33 to the cleaning tank 26, thus forming a circulation of cleaning water to clean the glue spray head 32.

[0038] Furthermore, the multiple storage racks 9 of the labeling mechanism 4 are inclined downwards toward the conveyor 7. The storage racks 9 of the labeling mechanism 4 are provided with baffle strips 35 around their front sides, and the baffle strips 35 abut against the edges of the label. The crossbar 15 of the labeling mechanism 4 is provided with multiple adsorption boxes 36. The bottom surface of each adsorption box 36 is provided with a pressure plate 37, and the pressure plate 37 is provided with multiple adsorption ports 38 communicating with the adsorption boxes 36. The labeling mechanism 4 also includes a first mounting base 39, a first lifting base 40, and a fourth driver 41. The first mounting base 39 is located at the lower part of the conveyor frame 1. The first lifting base 40 is slidably connected to the first mounting base 39 and is provided with a rack. The fourth driver 41 is located on the first mounting base 39, and the output end of the fourth driver 41 meshes with the rack of the first lifting base 40 via a drive gear. The top surface of the first lifting base 40 is provided with a top seat 46 extending from the top surface of the conveyor frame 1. Figures 1 to 16 As shown, the front side of the label abuts against the baffle strip 35 to prevent the label from falling off the storage rack 9. The label material is elastic and bendable so that the label can be removed from the label storage rack 9 after the adsorption box 36 adsorbs the label. When the egg carton is transported to the labeling mechanism 4 along the bracket 11, the pressure plate 37 of the adsorption box 36 can be equipped with a vacuum suction cup at the adsorption port 38. The vacuum suction cup is connected to the adsorption box 36, and the adsorption box 36 can be connected to an external vacuum generator (not shown in the figure). The pressure plate 37 of the adsorption box 36 abuts against the label located at the front of the storage rack 9. The vacuum suction cup adsorbs the label and keeps it flat to prevent the label from wrinkling during the adsorption process. Then, the drive disc 20 of the labeling mechanism 4 drives the connecting rod 21 to swing, causing one end of the second swing arm 14 to swing upward and the other end of the second swing arm 14 to swing downward. The second swing arm 14 drives the first swing arm 13 to swing outward, and the first swing arm 13 slides along the mounting post 18 of the mounting plate 16 through the slide groove, causing the first swing arm 13 to swing. The first swing arm 13 swings smoothly from an inclined state to a vertical state, so that the adsorption box 36 swings from an inclined state to a horizontal state and pulls the adsorbed label paper out from the baffle strip 35 of the storage rack 9, so that the adsorption box 36 places the adsorbed label paper on the egg carton after spraying glue. Then, the drive disc 20 drives the first swing arm 13, the second swing arm 14 and the adsorption box 36 to reset through the connecting rod 21, and so on to perform the paper picking action. In addition, the first mounting base 39 and the first lifting base 40 can be slidably connected through the structure of slide rail and slider. The fourth driver 41 can be a servo motor. When the adsorption box 36 swings from an inclined state to a horizontal state, the fourth driver 41 drives the lifting base to move upward through the drive gear and rack. The top base 46 can be provided with a slot to make way for the bracket 11, so that the top base 46 extends from the bracket 11 and lifts the egg carton after spraying glue, so that the surface of the egg carton sprayed with glue is in contact with the label paper on the bottom surface of the adsorption box 36 and the label paper is adhered to the egg carton.

[0039] Further, the pressing mechanism 5 includes a second mounting base 42, a second lifting base 43, and a fifth driver 44. The second lifting base 43 is slidably connected to the second mounting base 42, and a rack is provided on the second lifting base 43. The fifth driver 44 is disposed on the second mounting base 42, and the output end of the fifth driver 44 meshes with the rack of the second lifting base 43 through a drive gear. One pressing mechanism 5 is disposed on the top surface of the conveyor frame 1 via a mounting bracket 10, and the other pressing mechanism 5 is disposed on the lower part of the conveyor frame 1. A limit pressure seat 45 is provided on the bottom surface of the second lifting base 43 located on the top surface of the conveyor frame 1, and a top seat 46 extending from the top surface of the conveyor frame 1 is provided on the top surface of the second lifting base 43 located at the lower part of the conveyor frame 1. Figures 1 to 16 As shown, when the egg carton is conveyed along the support 11 to the pressing mechanism 5, the fifth driver 44 drives the drive gear to rotate. The drive gear drives the limiting pressure seat 45 or the top seat 46 on the second lifting seat 43 to move up and down through the rack. The top seat 46 can be provided with a slot to make way for the support 11 so that the top seat 46 can extend from the conveyor frame 1 and lift the egg carton. The limiting pressure seat 45 can be provided with a limiting groove to accommodate the egg carton. The top seat 46 lifts the egg carton into the limiting groove of the limiting pressure seat 45 for pressing and shaping.

[0040] Furthermore, the stacking mechanism 6 has a crossbar 15 with multiple second support plates. The bottom surface of each second support plate has multiple limiting frames and multiple second suction cups 47. The limiting frames limit the egg carton. The stacking mechanism 6 also includes second telescopic devices 48, push plates 49, and slides 50. The frame 8 has slide rods corresponding to the storage racks 9 above it, and slides 50 are slidably connected to the slide rods. Multiple second telescopic devices 48 are located on the top of the frame 8, and their output ends are connected to the slides 50. Each slide 50 has a lifting cylinder 51, and its output end is connected to the push plate 49, which can drive the push plate 49 into the storage rack 9. Figures 1 to 16As shown, when the egg carton is conveyed along the support 11 to the stacking mechanism 6, the second suction cup 47 can be a vacuum suction cup. The second suction cup 47 adsorbs the processed egg carton, and the limiting frame abuts against the egg carton for limiting. Subsequently, the drive disc 20 of the stacking mechanism 6 drives the connecting rod 21 to swing, causing one end of the second swing arm 14 to swing downward and the other end of the second swing arm 14 to swing upward. The second swing arm 14 drives the first swing arm 13 to swing towards the storage rack 9, and the first swing arm 13 slides along the mounting post 18 of the mounting plate 16 through the slide groove, so that the first swing arm 13 swings smoothly from the vertical state to the horizontal state. In this state, the second support plate swings from a horizontal to a vertical position, thereby placing the egg carton into the storage rack 9, and the second suction device 47 stops suctioning the egg carton. The storage rack 9 of the stacking mechanism 6 can be equipped with a limiting rod so that the limiting rod abuts against the egg carton, allowing the egg carton to be placed in the storage rack 9. It should be noted that when there is no egg carton in the storage rack 9 of the stacking mechanism 6, the push plate 49 can extend into the storage rack 9. The push plate 49 is a concave plate so that when the egg carton is placed into the storage rack 9, the push plate 49 is misaligned with the limiting rod, and there is a gap between the push plate 49 and the front side of the egg storage rack 9, such as the thickness of three to five stacked egg cartons. The lifting cylinder 51 can counteract the egg cartons and work with the limiting frame to limit the egg cartons, ensuring that the egg cartons are placed vertically in the storage rack 9. After three to five egg cartons are stacked, the stacked egg cartons can limit each other. In this way, the lifting cylinder 51 can drive the push plate 49 to move upward and extend out of the storage rack 9. The stacking mechanism 6 can be connected to the control host (not shown in the figure). After the stacking mechanism 6 completes one movement of the egg cartons from the conveyor to the storage rack 9, it can serve as a conveying signal for an egg carton. After three to five egg cartons are stacked, the lifting cylinder 51 controls the push plate 49 to extend out of the egg carton storage rack 9. In addition, a receiving egg carton can be set behind the storage rack 9. The storage box (not shown in the figure) has a second telescopic device 48, which can be a telescopic cylinder. After the stacking of fifty egg boxes is completed, the second telescopic device 48 can drive the push plate 49 to move to the front of the storage rack 9 via the slide 31. The lifting cylinder 51 drives the push plate 49 to move downward and abut against the stacked egg boxes. The second telescopic device 48 drives the push plate 49 via the slide 31 to push the stacked egg boxes out from the rear of the storage rack 9. Finally, the second telescopic device 48 and the lifting cylinder 51 drive the push plate 49 to return to a position with a gap from the front of the storage rack 9, so that the egg boxes can be re-stacked in the storage rack 9 and this cycle can be repeated.
