Description

Technical Field

[0001] The utility model relates to the field of carton gluing machines, and particularly relates to an automatic carton gluing machine. Background Art

[0002] The carton gluing machine is an essential processing device in carton processing. The gluing part is fixed on the bracket so that the gluing part can be suspended, enabling the corrugated paper to pass under the gluing part. The corrugated paper is cut into pieces. People fold the opposite ends of the corrugated paper to the same side, place the folded corrugated paper at one end against the upper surface of the guide plate, and place the folded corrugated paper at the other end against the lower surface of the guide plate. People push the corrugated paper so that the corrugated paper passes through the gluing part. Thus, the glue flows from the glue storage tank to the surface of the corrugated paper under the guide plate through the infusion tube and the glue outlet channel. By the push of people, the glued corrugated paper extends into the rolling part, and two rolling rollers respectively abut against the corrugated paper, causing the corrugated paper to slide away from the gluing part and overlapping the folded corrugated paper with each other, so that the folded corrugated paper is bonded by the glue. This method can only be used for regular objects with uniform width, has many limiting conditions, is difficult to produce generally, and is huge in volume, which is not conducive to production and processing.

Specific embodiments

[0024] The following further describes the present utility model in conjunction with the attached Figures 1-8 drawings and embodiments.

[0025] Such as Figures 1-3As shown in the figure, an automatic carton gluing and sealing machine includes a main frame 1, a control machine 2, an automatic gluing device 3, a glue storage tank 4 and a placement table 5. The automatic gluing device 3, the placement table 5, the glue storage tank 4 and the control machine 2 are all arranged on the main frame 1. The control machine 2 is connected to the automatic gluing device 3. The automatic gluing device 3 is used for gluing and sealing the workpieces to be processed on the placement table 5. The glue storage tank 4 is located between the drive motor 7 and the placement table 5. The automatic gluing device 3 includes a mounting frame 6, a drive motor 7, a horizontal displacement drive mechanism, a longitudinal displacement drive mechanism and a gluing frame 14. The drive motor 7, the horizontal displacement drive mechanism and the longitudinal displacement drive mechanism are all mounted on the mounting frame 6. The drive motor 7 is connected to the control machine 2. The drive motor 7 is drivingly connected to the horizontal displacement drive mechanism and the longitudinal displacement drive mechanism through a provided driving shaft 8. The horizontal displacement drive mechanism is used to control the horizontal displacement of the gluing frame 14. The longitudinal displacement drive mechanism is used to control the longitudinal displacement of the gluing frame 14. The gluing frame 14 is used for gluing the glue from the glue storage tank 4 and gluing on the placement table 5.

[0026] As Figures 4-5 shown, the longitudinal displacement drive mechanism includes a first transmission shaft 9, a guide block 11 and a longitudinal pressure block 32. A first cam 10 is provided on the first transmission shaft 9. The first transmission shaft 9 is in gear transmission connection with the driving shaft 8. A first cam 10 is provided on the first transmission shaft 9. One end of the guide block 11 facing away from the gluing frame 14 is movably hinged to the mounting frame 6. The upper surface of the guide block 11 is in abutting cooperation with the first cam 10. A pressure spring 12 is provided on the lower surface of the guide block 11. The bottom of the pressure spring 12 is connected to the mounting frame 6. A pressure rod 13 is movably sleeved in the guide block 11. The outer end of the pressure rod 13 is movably hinged to one side of the longitudinal pressure block 32. The longitudinal pressure block 32 is connected to the gluing frame 14. When the first cam 10 presses down the guide block 11, the guide block 11 turns down against the elastic force of the pressure spring 12. At this time, the pressure rod 13 drives the gluing frame 14 to move downward through the longitudinal pressure block 32. When the first cam 10 turns up and releases the guide block 11, the guide block 11 turns up under the elastic force of the pressure spring 12. At this time, the pressure rod 13 drives the gluing frame 14 to move upward through the longitudinal pressure block 32. The first transmission shaft 9 is in meshing transmission with the driving shaft 8 through a provided second transmission shaft 15. The first transmission shaft 9 and the second transmission shaft 15 form a gear transmission mechanism. The gear transmission mechanism is a speed reduction transmission mechanism. The gear transmission mechanism is used for the speed reduction and stable transmission of the drive motor 7. As Figure 5 shown in the figure, the upper surface of the guide block 11 is provided with an outwardly protruding movable wheel 16. The movable wheel 16 is in movable abutting cooperation with the first cam 10. The first cam 10 controls the up and down movement of the guide block 11 by abutting against the movable wheel 16.

[0027] As Figure 7As shown, the horizontal displacement transmission mechanism includes a third transmission shaft 17, a swing rod 18 and a thrust rod 19. The third transmission shaft 17 is movably installed on the mounting bracket 6. The third transmission shaft 17 is in gear transmission connection with the driving shaft 8. A second cam 20 is provided at the outer end of the third transmission shaft 17. The upper end of the swing rod 18 is movably hinged to the mounting bracket 6. The hinge between the swing rod 18 and the mounting bracket 6 is located above the second cam 20. One side of the swing rod 18 is in abutting cooperation with the second cam 20. The lower end of the swing rod 18 is hinged to the thrust rod 19. The outer end of the thrust rod 19 is hinged to a fixed block 21 provided, and the fixed block 21 is fixedly connected to the caulking frame 14. When the convex portion of the second cam 20 abuts on the swing rod 18, the swing rod 18 rotates relative to the hinge point to push the thrust rod 19 axially forward. The thrust rod 19 drives the caulking frame 14 to move away from the mounting bracket 6 through the fixed block 21. When the convex portion of the second cam 20 leaves the swing rod 18, the swing rod 18 rotates back relative to the hinge point to drive the thrust rod 19 to axially reset. The thrust rod 19 drives the caulking frame 14 to move closer to the mounting bracket 6 through the fixed block 21. An active disk protruding relative to the swing rod 18 is provided at the lower part of the swing rod 18 of the present application. The active disk can rotate relative to the swing rod 18. The active disk is in abutting cooperation with the second cam 20. The second cam 20 acts on the active disk to push the swing rod 18 to swing. The active disk has two functions: First, it is adapted to the second cam 20 to improve the stability of transmission; Second, the active disk itself generates a corresponding gravity effect relative to the swing rod 18, which is convenient for the reset of the swing rod 18.

[0028] As Figure 8As shown, the sealant application frame 14 includes a movable frame 22 and a sealant suction block 23 fixedly connected to the lower end of the movable frame 22. The movable frame 22 itself has a trapezoidal frame structure with a smaller upper part and a larger lower part. The movable frame 22 forms a limit fit with the longitudinal pressure block 32. A central shaft 24 is provided inside the movable frame 22. The central shaft 24 and the longitudinal track hole provided in the longitudinal pressure block 32 form a guide rail fit. A lower spring 25 is sleeved on the lower part of the central shaft 24. The upper end of the lower spring 25 is connected to the lower end of the longitudinal pressure block 32, and the lower end of the lower spring 25 is connected to the upper end face of the bottom of the movable frame 22. The lower spring 25 is used to generate an upward elastic force on the longitudinal pressure block 32. When the guide block 11 drives the longitudinal pressure block 32 to move downward, at this time, the longitudinal pressure block 32 drives the entire sealant application frame 14 to move downward through the lower spring 25 for glue sticking or sealant application. Two longitudinal side shafts 26 are provided inside the movable frame 22, respectively located on both sides of the central shaft 24. Two sliding blocks 27 are movably sleeved on the two longitudinal side shafts 26. The two sliding blocks 27 form a limit fit with the movable frame 22. The upper ends of the two sliding blocks 27 are both connected with upper springs 28 sleeved on the longitudinal side shafts 26. The upper ends of the upper springs 28 form a top contact fit with the lower end face of the upper part of the movable frame 22. The two sliding blocks 27 are both fixedly connected with a transverse baffle 29. The transverse baffle 29 can horizontally displace or longitudinally displace relative to the main frame 1.

[0029] As Figure 1 shown, the transverse baffle 29 has a U-shaped structure. Guide rail blocks 30 are provided on both sides of the main frame 1. The guide rail blocks 30 and the longitudinal track shafts 31 provided on the main frame 1 form a guide rail fit. The horizontal track holes provided in the guide rail blocks 30 and the ends of the transverse baffle 29 form a horizontal guide rail fit.

[0030] Operating principle: The main drive shaft 8, the second drive shaft 15, and the first drive shaft 9 are sequentially driven. The first cam 10 on the first drive shaft 9 continuously makes a regular pressing action on the guide block 11. Under the interaction of the pressure spring 12, the guide block 11 makes a regular up-and-down flip relative to the hinge point. The pressure rod 13 in the guide block 11 drives the sealant application frame 14 to make a regular up-and-down displacement movement through the longitudinal pressure block 32. At this time, it can be used for the sealant application frame 14 to stick glue to the glue storage tank 4 and apply sealant to the cardboard box.

[0031] The main drive shaft 8, the third drive shaft 17, and the second cam 20 are sequentially driven. The abutting action of the second cam 20 on the swing rod 18 causes the swing rod 18 to continuously swing relative to the hinge point. The swing rod 18 and the thrust rod 19 drive the entire sealant application frame 14 to make a regular horizontal displacement movement through the fixed block 21.

[0032] Under the control of the control machine 2 and the speed reduction transmission mechanism, the sealant application frame 14 shows a regular working process of moving downward to stick glue, moving upward and outward to above the cardboard box, and then moving downward to apply sealant.

[0033] An infrared sensor 33 for connecting to the control machine 2 is additionally provided on the mounting bracket 6. The infrared sensor 33 is used to detect the downward turning frequency of the guiding block 11 so as to detect the caulking frequency of the entire caulking machine. By collecting the data of the infrared sensor 33 and through the driving shaft 8, the control machine 2 can achieve the purpose of accurately controlling the caulking frequency.

[0034] Obviously, the above-mentioned embodiments of the present invention are merely examples for explaining the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the implementation manners here. And these obvious changes or modifications derived from the essence of the present invention still fall within the protection scope of the present invention.
