Technical Field
[0001] This utility model relates to the technical field of cardboard box production equipment, specifically a feeding device for a carton gluing machine. Background Technology
[0002] Carton gluing machines are key equipment in carton production, used to glue flat cartons into box shapes. During the feeding process, stacked cartons are typically picked up one by one and automatically conveyed onto the conveyor belt of the gluing machine. Existing carton gluing machine feeding devices have several shortcomings: First, stacked cartons easily accumulate dust or impurities on their surfaces during storage and handling. Direct feeding can cause these impurities to affect the subsequent gluing effect, leading to delamination or defective products. Second, cartons easily stick together due to static electricity. Traditional suction cup feeding devices may pick up multiple cartons at once, causing equipment jams or production interruptions, affecting the efficiency and continuity of automated production. Furthermore, traditional feeding devices are functionally limited, lacking an integrated design for effectively cleaning and separating cartons before picking them up. Therefore, there is an urgent need for a feeding device that can automatically clean the surface of cartons, effectively separate sticky cartons, and improve feeding accuracy and production efficiency.

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0012] Please see Figure 1 - Figure 3 A feeding device for a carton gluing machine includes a storage box 1, a conveyor table 2, a support frame 3, and a gripping component. The conveyor table 2 is provided on one side of the storage box 1, and a conveyor belt 201 is provided on the top of the conveyor table 2. The support frame 3 is provided above the storage box 1. A first electric push rod 4 is provided at the bottom of the inner cavity of the storage box 1. A lifting plate 5 is fixedly connected to the top output end of the first electric push rod 4. A first mounting groove 101 is provided on both side walls of the inner cavity of the storage box 1. A guide rod 102 is provided in the first mounting groove 101. A slider 1021 is slidably connected to the guide rod 102. The two ends of the lifting plate 5 are fixedly connected to the slider 1021. The top of the inner wall of the support frame 3 is provided with a second mounting groove 301. A lead screw 6 is provided in the second mounting groove 301. One end of the lead screw 6 is connected to the output end of the first motor 601 provided on the side wall of the support frame 3, and the other end is rotatably connected to the inner wall of the second mounting groove 301. A transmission block 7 is threadedly connected to the lead screw 6, and a gripping component is provided below the transmission block 7.
[0013] Through the above technical solution, the storage box 1 can be used to store cartons to be loaded. The first electric push rod 4 at the bottom of its inner cavity can drive the lifting plate 5 to lift upward. With the sliding cooperation of the guide rod 102 and the slider 1021 in the first mounting groove 101 on both sides of the inner cavity of the storage box 1, the lifting plate 5 can be lifted and lowered smoothly to continuously lift the cartons. At the same time, the lead screw 6 in the second mounting groove 301 at the top of the inner wall of the support frame 3 rotates under the drive of the first motor 601, which can drive the transmission block 7 connected to it to move horizontally. This allows the gripping component below the transmission block 7 to move precisely between the storage box 1 and the conveyor 2. Finally, combined with the conveyor belt 201 at the top of the conveyor 2, the automated loading process of automatically lifting, stably gripping and accurately conveying the cartons in the storage box 1 to the gluing machine is realized, ensuring the stability and continuity of loading.
[0014] This utility model provides a technical solution in which the gripping component includes a second electric push rod 8, a connecting frame 9 and a vacuum suction cup 10. The bottom of the transmission block 7 is fixedly connected to the top of multiple second electric push rods 8. The bottom output end of the second electric push rod 8 is fixedly connected to the top of the connecting frame 9. Vacuum suction cups 10 are provided at the four corners of the bottom of the connecting frame 9. A cleaning component is also provided inside the connecting frame 9.
[0015] Through the above technical solution, the multiple second electric push rods 8 at the bottom of the transmission block 7 can drive the connecting frame 9 to move up and down, thereby precisely controlling the distance between the vacuum suction cups 10 at the four corners of the bottom of the connecting frame 9 and the carton, which facilitates the stable adsorption or release of the carton by the vacuum suction cups 10; at the same time, the cleaning components set inside the connecting frame 9 can pre-treat the surface of the carton before the vacuum suction cups 10 adsorb it, ensuring that the surface of the carton is clean, improving the reliability of the feeding process and the subsequent processing quality of the carton.
[0016] This utility model provides a technical solution in which the cleaning assembly includes a third electric push rod 11, a mounting frame 12 and a cleaning roller 13. The third electric push rod 11 is provided on the top of the inner wall of the connecting frame 9. The bottom output end of the third electric push rod 11 is fixedly connected to the top of the mounting frame 12. The cleaning roller 13 is rotatably connected inside the mounting frame 12. The cleaning roller 13 is driven by a second motor 1301 provided on the side wall of the mounting frame 12.
[0017] Through the above technical solution, the third electric push rod 11 on the top of the inner wall of the connecting frame 9 can drive the mounting frame 12 to move up and down, thereby controlling the contact or separation of the cleaning roller 13 inside the mounting frame 12 with the surface of the carton; when cleaning is required, the third electric push rod 11 pushes the mounting frame 12 down to make the cleaning roller 13 contact the surface of the carton, and at the same time, the second motor 1301 on the side wall of the mounting frame 12 drives the cleaning roller 13 to rotate, so as to effectively remove dust and impurities from the surface of the carton; this structure allows the cleaning component to complete pretreatment before the vacuum suction cup 10 adsorbs the carton, avoiding dust from affecting the bonding quality of the subsequent gluing process, and improving the functionality and practicality of the feeding device.
[0018] This utility model provides a technical solution in which a mounting plate 14 is provided on the upper end of the side of the support frame 3 away from the conveyor table 2, a ventilation groove 1401 is provided on the lower end of the mounting plate 14, a blowing device 15 is provided on the lower end of the side of the mounting plate 14 away from the conveyor table 2, and a plurality of blowing nozzles 16 are provided on the blowing device 15, and the blowing nozzles 16 are provided in the ventilation groove 1401.
[0019] Through the above technical solution, the mounting plate 14 on the support frame 3 provides a stable mounting carrier for the blowing device 15. The ventilation slot 1401 at its lower end allows the airflow blown out by the blowing nozzle 16 to directly act on the carton. When the vacuum suction cup 10 picks up the carton and rises, the blowing device 15 on one side of the mounting plate 14 can blow airflow to the surface of the carton and between the cartons through multiple blowing nozzles 16. On the one hand, it can further blow away the residual dust that the cleaning components have not cleaned, thus doubly ensuring the cleanliness of the carton surface and improving the bonding quality of the subsequent gluing process. On the other hand, it can use the airflow impact force to separate the cartons that are stuck together due to static electricity, moisture and other factors, preventing the vacuum suction cup 10 from picking up the carton below and causing the feeding to get stuck. This effectively improves the stability and reliability of the feeding process.
[0020] The working principle of this utility model is as follows: First, the first electric push rod 4 inside the storage bin 1 is activated, pushing the lifting plate 5 upward to lift the stacked cartons. The guide rod 102 in the first mounting groove 101 on both sides of the inner cavity of the storage bin 1 slides with the slider 1021 to ensure that the lifting plate 5 rises and falls smoothly. Then, the first motor 601 on the side wall of the support frame 3 drives the lead screw 6 in the second mounting groove 301 to rotate, so that the transmission block 7 on the lead screw 6 drives the gripping component to move horizontally above the storage bin 1. At this time, the third electric push rod 11 in the connecting frame 9 pushes the mounting frame 12 down, so that the cleaning roller 13 in the mounting frame 12 contacts the surface of the cartons. The second motor 1301 drives the cleaning roller 13 to rotate to clean the dust on the surface of the cartons. At the same time, the lead screw 6 drives the cleaning roller 13 to move laterally to complete the cleaning of the surface of the cartons.
[0021] After cleaning, the third electric push rod 11 drives the mounting frame 12 and the cleaning roller 13 to retract into the connecting frame 9. The second electric push rod 8 at the bottom of the transmission block 7 pushes the connecting frame 9 down, so that the vacuum suction cups 10 at the four corners of the bottom of the connecting frame 9 contact the carton and adsorb it. At the same time, the blowing device 15 on the mounting plate 14 on one side of the support frame 3 blows air onto the carton through multiple blowing nozzles 16 in the ventilation slot 1401, which further removes residual dust and separates the cartons that may stick together. Afterward, the second electric push rod 8 drives the connecting frame 9 and the adsorbed carton to rise. The first motor 601 drives the lead screw 6 again to move the transmission block 7 to move the gripping component above the conveyor table 2. The vacuum suction cups 10 release the carton so that it falls onto the conveyor belt 201. Finally, the conveyor belt 201 transports the carton to the gluing machine for subsequent processing.
[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
