Description

Technical Field

[0001] The invention relates to the field of box gluing machines, and in particular to an automatic box gluing machine. Background Art

[0002] The carton gluing machine is an indispensable processing device in carton processing. The gluing part is fixed on the bracket so that the gluing part can be suspended and the corrugated paper can pass under the gluing part. The corrugated paper is cut into pieces of boards. People fold the two opposite ends of the corrugated paper to the same side, and make the folded corrugated paper at one end touch the upper surface of the guide plate, and then make the folded corrugated paper at the other end touch the lower surface of the guide plate. People push the corrugated paper to pass through the gluing part, so that the glue passes through the infusion tube and the glue outlet channel and flows from the glue storage box to the surface of the corrugated paper on the lower surface of the guide plate. The corrugated paper coated with glue by people's push extends into the rolling part, and the two rolling rollers respectively touch the corrugated paper, so that the corrugated paper slides to the side away from the gluing part, and the folded corrugated paper overlaps each other, so that the folded corrugated paper is bonded by glue. This method can only be used with regular objects of uniform width, which has many restrictions and is difficult to mass produce. It is also huge in size and not conducive to production and processing.

The driving wheel is located in the glue storage tank and contacts with the glue in the glue storage tank, and is used to invade the glue in the glue storage tank into the conveyor belt. The conveyor belt conveys the glue liquid to the bottom of the pneumatic gluing device. The pneumatic gluing device comprises a moving frame, a pneumatic element, a gluing frame, and a gluing head connected to the lower end of the gluing frame. The pneumatic element is fixed on the moving frame and connected to the gluing frame, and is used to control the up and down movement of the gluing frame.

DETAILED DESCRIPTION

[0021] The following is combined with Figure 1-8 The present invention is further illustrated with examples.

[0022] like Figure 1-3 As shown, an automatic box gluing machine includes a main frame 1, a control machine 2, an automatic gluing device 3, a glue storage tank 4 and a storage table 5. The automatic gluing device 3, the storage 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 to glue the processed parts on the storage table 5. The glue storage tank 4 is located between the transmission motor 7 and the storage table 5. The automatic gluing device 3 includes a mounting frame 6, a transmission motor 7, a horizontal displacement transmission mechanism, a longitudinal displacement transmission mechanism, and a gluing frame 14. The transmission motor 7, the horizontal displacement transmission mechanism, and the longitudinal displacement transmission mechanism are all installed on the mounting frame 6. The transmission motor 7 is connected to the control machine 2. The transmission motor 7 is connected to the horizontal displacement transmission mechanism and the longitudinal displacement transmission mechanism through a driving shaft 8. The horizontal displacement transmission mechanism is used to control the horizontal displacement of the gluing frame 14, and the longitudinal displacement transmission mechanism is used to control the longitudinal displacement of the gluing frame 14. The gluing frame 14 is used for the glue in the glue storage tank 4 and the gluing on the storage table 5.

[0023] like Figure 4-5As shown, the longitudinal displacement transmission mechanism includes a first transmission shaft 9, a guide block 11, and a longitudinal pressure block 32. The first transmission shaft 9 is provided with a first cam 10. The first transmission shaft 9 and the driving shaft 8 form a gear transmission connection. The first transmission shaft 9 is provided with a first cam 10. The guide block 11 is movably hinged to the mounting frame 6 at one end facing away from the glue frame 14. The upper surface of the guide block 11 is in conflict with the first cam 10. The lower surface of the guide block 11 is provided with a pressure spring 12. The bottom of the pressure spring 12 is connected to the mounting frame 6. The guide block 11 A pressure rod 13 is movably sleeved inside, and the outer end of the pressure rod 13 is movably hinged to one side of a 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 to overcome 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 to release the guide block 11, the guide block 11 turns up due to 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 engaged with the transmission active shaft 8 through the second transmission shaft 15. The first transmission shaft 9 and the second transmission shaft 15 constitute a gear transmission mechanism. The gear transmission mechanism is a reduction transmission mechanism. The gear transmission mechanism is used for deceleration and stable transmission of the transmission motor 7. Figure 5 As shown in , the upper surface of the guide block 11 is provided with a movable wheel 16 protruding outward, and the movable wheel 16 and the first cam 10 form a movable abutment cooperation. The first cam 10 controls the up and down movement of the guide block 11 by abutting against the movable wheel 16.

[0024] like 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 mounted on the mounting frame 6. The third transmission shaft 17 is gear-connected to 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 frame 6. The hinge between the swing rod 18 and the mounting frame 6 is located above the second cam 20. One side of the swing rod 18 is abutted against 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, and the fixed block 21 is fixedly connected to the gluing frame 14. When the protrusion of the second cam 20 is against the swing rod 18, the swing rod 18 rotates relative to the hinge point to push the thrust rod 19 axially forward, and the thrust rod 19 drives the glue rack 14 to move away from the mounting frame 6 through the fixed block 21. When the protrusion of the second cam 20 leaves the swing rod 18, the swing rod 18 rotates relative to the hinge point to drive the thrust rod 19 to reset axially, and the thrust rod 19 drives the glue rack 14 to move closer to the mounting frame 6 through the fixed block 21. The lower part of the swing rod 18 of the present application is provided with a movable disk protruding relative to the swing rod 18, and the movable disk can rotate relative to the swing rod 18, and the movable disk and the second cam 20 form abutment. The second cam 20 pushes the swing rod 18 to swing by acting on the movable disk. The movable disk has two functions: first, it adapts to the second cam 20 to improve the stability of the transmission; second, the movable disk itself generates a corresponding gravity effect relative to the swing rod 18, which is convenient for the resetting of the swing rod 18.

[0025] like Figure 8As shown, the glue-applying frame 14 includes a movable frame 22 and a glue-absorbing block 23 fixedly connected to the lower end of the movable frame 22. The movable frame 22 itself is a trapezoidal frame structure that is small at the top and large at the bottom. The movable frame 22 and the longitudinal pressure block 32 form a limit fit, and a central axis 24 is provided in the movable frame 22. The central axis 24 and the longitudinal track hole provided in the longitudinal pressure block 32 form a guide rail fit, and the lower part of the central axis 24 is sleeved with a lower spring 25, 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 surface of the bottom of the movable frame 22, and 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, the longitudinal pressure block 32 drives the entire glue-applying frame 14 to move downward through the lower spring 25 to glue or apply glue. The movable frame 22 is provided with two longitudinal side shafts 26 respectively located on both sides of the central shaft 24. The two longitudinal side shafts 26 are movably sleeved with sliders 27. The two sliders 27 form a limit fit with the movable frame 22. The upper ends of the two sliders 27 are connected with upper springs 28 sleeved with the longitudinal side shafts 26. The upper ends of the upper springs 28 form abutment fit with the upper lower end surface of the movable frame 22. The two sliders 27 are fixedly connected to a transverse baffle 29, and the transverse baffle 29 can be horizontally displaced or longitudinally displaced relative to the main frame 1.

[0026] like Figure 1 As shown, the transverse baffle 29 is of a U-shaped structure, and 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, and the horizontal track holes provided on the guide rail blocks 30 form a horizontal guide rail fit with the ends of the transverse baffle 29.

[0027] Operation principle: the driving shaft 8, the second transmission shaft 15, and the first transmission shaft 9 are driven in sequence, and the first cam 10 on the first transmission shaft 9 continuously and regularly presses the guide block 11, and then through the interaction of the pressure spring 12, the guide block 11 is regularly turned up and down relative to the hinge, and the pressure rod 13 in the guide block 11 makes the gluing frame 14 move up and down regularly through the longitudinal pressure block 32. At this time, the gluing frame 14 can be used to glue the glue storage tank 4 and glue the cartons.

[0028] The driving shaft 8, the third transmission shaft 17 and the second cam 20 are driven in sequence, and the abutment 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 make the entire glue spraying frame 14 perform regular horizontal displacement movement through the fixed block 21.

[0029] Under the control of the control machine 2 and the reduction transmission mechanism, the gluing frame 14 is moved downward to glue, moved upward and outward to the top of the carton, and moved downward to glue.

[0030] The mounting frame 6 is provided with an infrared sensor 33 connected to the control machine 2, and the infrared sensor 33 is used to detect the downward turning frequency of the guide block 11 and then detect the gluing frequency of the entire gluing machine. The control machine 2 collects data from the infrared sensor 33 and can achieve the purpose of accurately controlling the gluing frequency through the active shaft 8.

[0031] Obviously, the above embodiments of the present invention are merely examples for illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to exhaust all implementation methods here. However, these obvious changes or modifications derived from the essential spirit of the present invention still fall within the protection scope of the present invention.
