It is mainly used for gluing single corrugated cardboard to meet the requirements of multi-variety and small and medium-sized batch production. It is suitable for the packaging needs of export products such as food and cotton. It is an ideal carton equipment. It has the advantages of high efficiency, easy operation, good performance and reliable operation. It is a necessary equipment for the packaging carton industry. The box gluing machine is generally composed of a paper feeding part, a gluing part, a folding part and a discharge part.

[0003] A Chinese utility model patent with publication number CN213564650U discloses a carton gluing machine with uniform gluing, comprising a frame, a glue box for containing glue, a gluing wheel for gluing being rotatably connected to the frame, a rotating shaft being fixedly connected to the gluing wheel, a motor being arranged outside the glue box, an end of the rotating shaft passing through the glue box being fixedly connected to the rotating end of the motor, the rotating shaft and the gluing wheel being driven by the motor to rotate, so that the glue in the glue box adheres to the gluing wheel, and when the cardboard passes over the gluing wheel, the glue attached to the gluing wheel is smeared onto the cardboard, thereby completing the gluing step.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: during use, the above-mentioned device dips the glue into the glue wheel and then applies it to the cardboard. However, under the influence of the external environment temperature and humidity, the concentration and adhesion ability of the glue change, so it cannot be guaranteed that the amount of glue attached to the glue wheel each time is consistent, so that the glue applied to the cardboard is not uniform, affecting the subsequent bonding effect. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a carton gluing machine with uniform gluing.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions: a carton gluing machine with uniform gluing, comprising a paper feeding mechanism, a gluing mechanism, a folding mechanism, and a discharging mechanism, wherein the gluing mechanism comprises a frame and a workbench arranged on the frame, a glue box is arranged in the frame, a discharge pipe is arranged on the glue box, a vertically arranged rotating pipe is rotatably arranged on the workbench, a smearing block is arranged at the upper end of the rotating pipe, and the lower end passes through the workbench and is rotatably arranged in the discharge pipe, a glue outlet communicated with the tube cavity of the rotating pipe is vertically penetrated in the smearing block, A rotating sealing ring is provided on the outer wall of the lower end of the rotating tube, and the outer edge of the rotating sealing ring abuts against the inner wall of the discharge tube. A plurality of bristles are provided at circumferential intervals on the top of the smearing block. A driving component for driving the rotating tube to rotate is provided in the frame. A push plate is horizontally provided in the glue box, and a sealing rubber ring is provided on the edge of the push plate, and the outer edge of the sealing rubber ring abuts against the inner wall of the glue box.

[0007] By adopting the above technical scheme, a frame, a workbench, a rotating tube, a glue box, a driving component, a pushing component, a supporting component, and a pressing component are arranged, and the cardboard is conveyed to the folding mechanism by the paper feeding mechanism. During the conveying process, the glue-coated area of ​​the cardboard will contact the bristles under the action of the pressing component. The pushing component drives the push plate to rise to squeeze the glue in the glue box upward, so that the glue is discharged from the glue outlet through the discharge pipe and the rotating tube and adheres to the glue-coated area of ​​the cardboard, thereby ensuring that the amount of glue extruded is always consistent. The driving component drives the rotating tube to rotate to drive the bristles to rotate, and the glue squeezed into the glue-coated area of ​​the cardboard is broken up, thereby ensuring that the glue is evenly applied to the glue-coated area of ​​the cardboard, thereby ensuring the firmness of the subsequent cardboard adhesion.

[0008] Furthermore, a mounting plate is provided in the frame, and the driving assembly includes a driving motor vertically arranged on the mounting plate, a rotating shaft is provided upwardly and coaxially at the end of the output shaft of the driving motor, the upper end of the rotating shaft is rotatably provided at the bottom of the workbench, a first driving wheel is provided on the rotating shaft, and a first driven wheel is coaxially provided on the rotating tube, and the first driving wheel and the first driven wheel are connected by a first transmission belt.

[0009] By adopting the above technical solution, a mounting plate, a driving motor, a rotating shaft, a first active wheel, a first driven wheel, and a first transmission belt are set. The driving motor drives the rotating shaft to rotate and drives the first active wheel to rotate. Under the action of the first transmission belt, the first driven wheel rotates and drives the rotating tube to rotate.

[0010] Furthermore, the pushing assembly includes a connecting rod vertically slidably arranged at the bottom of the plastic box, the upper end of the connecting rod is connected to the push plate, and the lower end is coaxially provided with a threaded rod, a rotating block is rotatably arranged on the mounting plate, and the rotating block is spirally matched with the threaded rod through a threaded hole, a connecting plate is provided at the bottom of the threaded rod, a guide rod is vertically arranged on the connecting plate, a guide hole is provided on the mounting plate, the guide rod is slidably arranged in the guide hole, and a deceleration unit for driving the rotating block to rotate is provided on the mounting plate.

[0011] By adopting the above technical solution, a connecting rod, a threaded rod, a rotating block, a connecting plate, a guide rod, a guide hole, and a reduction unit are provided. The rotating block is driven to rotate by the reduction unit. Since the threaded rod is circumferentially limited by the guide rod and the guide hole, the threaded rod rises, thereby driving the connecting rod and the push plate to rise, and the glue in the glue box is squeezed out from the discharge pipe.

[0012] Furthermore, the reduction unit includes a second driving wheel arranged on the rotating shaft, a vertically arranged rotating shaft is rotatably arranged on the mounting plate, a second driven wheel and a third driving wheel are coaxially arranged on the rotating shaft, the second driving wheel and the second driven wheel are connected by a second transmission belt, a third driven wheel is arranged on the rotating block, a circular hole with a diameter greater than that of the threaded rod is vertically opened in the middle of the third driven wheel, the third driven wheel and the third driving wheel are connected by a third transmission belt, the diameter of the second driven wheel is greater than the diameters of the second driving wheel and the third driving wheel, and the diameter of the third driven wheel is greater than the diameter of the third driving wheel.

[0013] By adopting the above technical scheme, a second driving wheel, a rotating shaft, a second driven wheel, a third driving wheel, a second transmission belt, and a third driven wheel are set. The driving motor drives the rotating shaft to rotate, thereby driving the second driving wheel to rotate. Under the action of the second transmission belt, the second driven wheel rotates to drive the rotating shaft and the third driving wheel to rotate. Under the action of the third belt, the third driven wheel rotates to drive the rotating block to rotate. Since the diameter of the second driven wheel is larger than the diameters of the second driving wheel and the third driving wheel, and the diameter of the third driven wheel is larger than the diameter of the third driving wheel, the transmission ratio between the rotating shaft and the rotating block is reduced, thereby making it possible to increase the speed of the driving motor. While ensuring that the push plate rises steadily and slowly, the smearing block can rotate faster and spread the glue more evenly.

[0014] Furthermore, the support assembly includes vertical plates spaced apart on the workbench, rollers are rotatably arranged between the vertical plates, the top of the rollers is flush with the top of the smearing block, and the wheel core direction of the rollers is perpendicular to the moving direction of the cardboard.

[0015] By adopting the above technical solution, vertical plates and rollers are provided, and before the glue coating area of ​​the cardboard reaches the coating block, the rollers support the cardboard to ensure that the glue coating area of ​​the cardboard is in stable contact with the bristles.

[0016] Furthermore, the pressing assembly includes a supporting plate arranged on the workbench, a top plate is arranged on the supporting plate cantilevered above the coating head, two cylinders with downward openings are arranged at intervals on the top of the top plate, vertically arranged sliding rods are slidably arranged on the cylinders, the lower ends of the two sliding rods pass through the top plate and are jointly provided with a mounting frame, the sliding rod is located between the bottom of the cylinder and the top plate, a baffle is provided on the lower part of the rod body, the sliding rod is located between the baffle and the top of the cylinder and a compression spring is sleeved on the rod body, two rubber wheels arranged at intervals are rotatably provided on the mounting frame, the wheel core direction of the rubber wheels is perpendicular to the moving direction of the cardboard, one of the rubber wheels is located above the roller, and the other rubber wheel is located above the coating block.

[0017] By adopting the above technical solution, a support plate, a top plate, a cylinder, a slide rod, a mounting frame, a baffle, a compression spring, and a rubber wheel are arranged. When the cardboard passes through the smearing block, the rubber wheel provides downward pressure to ensure that the glue-coated area of ​​the cardboard is in contact with the bristles. By using the baffle and the compression spring, the rubber wheel can adapt to cardboards of different thicknesses. When thicker cardboard passes through, the rubber wheel is pushed upward by the cardboard, and the compression spring is compressed, thereby preventing the rubber wheel from damaging the cardboard due to the unchanged position.

[0018] In summary, the utility model has the following beneficial effects: in the present application, a frame, a workbench, a rotating tube, a glue box, a driving component, a pushing component, a supporting component, and a pressing component are provided, and the cardboard is conveyed to the folding mechanism by the paper feeding mechanism. During the conveying process, the glue-coated area of ​​the cardboard will contact the bristles under the action of the pressing component, and the pushing plate is driven to rise by the pushing component to squeeze the glue in the glue box upward, so that the glue is discharged from the glue outlet through the discharge pipe and the rotating tube and adheres to the glue-coated area of ​​the cardboard, thereby ensuring that the amount of glue extruded is always consistent, and the driving component is used to drive the rotating tube to rotate and drive the bristles to rotate, so as to break up the glue squeezed into the glue-coated area of ​​the cardboard, thereby ensuring that the glue is evenly applied to the glue-coated area of ​​the cardboard, thereby ensuring the firmness of the subsequent cardboard adhesion.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0025] like Figure 1-4 As shown, the embodiment of the present application discloses a carton gluing machine with uniform gluing, comprising a paper feeding mechanism 1, a gluing mechanism 10, a folding mechanism 2, and a discharge mechanism 3. The paper feeding mechanism 1 is used to transport the cardboard backward in sequence, the gluing mechanism 10 is used to apply glue on the gluing area of ​​the cardboard, the folding mechanism 2 folds the cardboard as needed, and during the folding process, the glue in the gluing area of ​​the cardboard bonds the two ends of the cardboard together, and then is discharged from the machine through the discharge mechanism 3.

[0026] Specifically, the gluing mechanism 10 includes a frame 11 and a workbench 12 arranged on the frame 11, a glue box 30 is arranged in the frame 11, a discharge pipe 31 and a feed pipe are arranged on the glue box 30, the upper end of the feed pipe passes through the workbench 12 and is spirally provided with a cover, and a sealing gasket is arranged on the top of the cover to ensure the sealing at the mouth of the feed pipe. A vertically arranged rotating tube 20 is rotatably arranged on the workbench 12, a smearing block 21 is arranged at the upper end of the rotating tube 20, and the lower end passes through the workbench 12 and is rotatably arranged in the discharge pipe 31. When specifically arranged, the rotating tube 20 is threadedly connected with the smearing block 21, so that the smearing block 21 of the appropriate size can be replaced according to the different smearing areas of different cardboards. A rotating sealing ring 23 is arranged on the outer wall of the lower end of the rotating tube 20, and the outer edge of the rotating sealing ring 23 abuts against the inner wall of the discharge pipe 31, so that when the rotating tube 20 is in a rotating state, the outer wall of the rotating tube 20 and the inner wall of the discharge pipe 31 are still in a sealed state. A glue outlet 22 connected to the lumen of the rotating tube 20 is vertically provided in the smear block 21, a push plate 32 is horizontally provided in the glue box 30, a sealing rubber ring 33 is provided on the edge of the push plate 32, and the outer edge of the sealing rubber ring 33 abuts against the inner wall of the glue box 30, and a pushing assembly 50 for driving the push plate 32 to move up and down is also provided in the frame 11. The pushing assembly 50 drives the push plate 32 to rise and squeeze the glue in the glue box 30 upward, so that the glue is discharged from the glue outlet 22 through the discharge tube 31 and the rotating tube 20 and attached to the glue coating area of ​​the cardboard, ensuring that the amount of glue extruded is always consistent. When glue needs to be added to the glue box 30, first unscrew the lid, then drive the push plate 32 to descend to the bottom of the glue box 30 through the pushing assembly 50, then pour the glue from the feed tube into the glue box 30, and finally screw the lid back onto the feed tube.

[0027] The frame 11 is provided with a mounting plate 13 and a driving assembly 40 for driving the rotating tube 20 to rotate. The driving assembly 40 includes a driving motor 41 vertically arranged on the mounting plate 13. A rotating shaft 42 is arranged coaxially upward and at the end of the output shaft of the driving motor 41. The upper end of the rotating shaft 42 is rotatably arranged at the bottom of the workbench 12 to ensure the stability of the rotating shaft 42 during rotation. A first driving wheel 43 is arranged on the rotating shaft 42, and a first driven wheel 44 is arranged coaxially on the rotating tube 20. The first driving wheel 43 and the first driven wheel 44 are connected by a first transmission belt 45. The driving motor 41 drives the rotating shaft 42 to rotate and drive the first driving wheel 43 to rotate. Under the action of the first transmission belt 45, the first driven wheel 44 rotates and drives the rotating tube 20 to rotate. A plurality of bristles 24 are arranged at intervals on the top of the smearing block 21. The rotating tube 20 rotates to drive the smearing block 21 and the bristles 24 to rotate, and the glue squeezed into the glue coating area of ​​the cardboard is scattered, ensuring that the glue is evenly smeared on the glue coating area of ​​the cardboard, and ensuring the firmness of the subsequent cardboard adhesion.

[0028] The pushing assembly 50 includes a connecting rod 51 which is vertically slidably arranged at the bottom of the glue box. The upper end of the connecting rod 51 is connected to the push plate 32, and the lower end is coaxially provided with a threaded rod 52, so that the push plate 32, the connecting rod 51, and the threaded rod 52 can be raised and lowered synchronously. A rotating block 53 is rotatably arranged on the mounting plate 13. The rotating block 53 is screwed with the threaded rod 52 through a threaded hole. A connecting plate 54 is arranged at the bottom of the threaded rod 52. A guide rod 55 is vertically arranged on the connecting plate 54. A guide hole 56 is arranged on the mounting plate 13. The guide rod 55 is slidably arranged in the guide hole 56, so that the guide rod 55 can slide in the guide hole 56. The rotating block 53 is rotated. Since the threaded rod 52 is circumferentially limited under the action of the guide rod 55 and the guide hole 56, the threaded rod 52 rises, thereby driving the connecting rod 51 and the push plate 32 to rise, and the glue in the glue box 30 is squeezed out from the discharge pipe 31.

[0029] During the setting, a reduction unit 80 for driving the rotating block 53 to rotate is arranged on the mounting plate 13, and the reduction unit 80 includes a second driving wheel 81 arranged on the rotating shaft 42. A vertically arranged rotating shaft is rotatably arranged on the mounting plate 13, and a second driven wheel 82 and a third driving wheel 83 are coaxially arranged on the rotating shaft. The second driving wheel 81 and the second driven wheel 82 are connected by a second transmission belt 84. The driving motor 41 drives the rotating shaft 42 to rotate, driving the second driving wheel 81 to rotate. Under the action of the second transmission belt 84, the second driven wheel 82 rotates to drive the rotating shaft and the third driving wheel 83 to rotate. A third driven wheel 85 is arranged on the rotating block 53, and the third driven wheel 85 is connected to the third driving wheel 83 by a third transmission belt 86, so that when the third driving wheel 83 rotates, the third driven wheel 85 is driven to rotate, thereby driving the rotating block 53 to rotate. The diameter of the second driven wheel 82 is larger than the diameters of the second driving wheel 81 and the third driving wheel 83, and the diameter of the third driven wheel 85 is larger than the diameter of the third driving wheel 83, so that the transmission ratio between the rotating shaft 42 and the rotating block 53 is reduced, so that the speed of the driving motor 41 can be increased, and while ensuring that the push plate 32 rises slowly and stably, the smearing block 21 can rotate faster and spread the glue more evenly. A circular hole with a diameter larger than that of the threaded rod 52 is vertically opened in the middle of the third driven wheel 85, which is used for the threaded rod 52 to pass through when it rises, so as to avoid interference between the threaded rod 52 and the third driven wheel 85.

[0030] In the specific setting, a support assembly 60 for supporting the cardboard is provided on the workbench 12. The support assembly 60 includes vertical plates 61 arranged at intervals on the workbench 12, and rollers 62 are rotatably arranged between the vertical plates 61. The top of the roller 62 is flush with the top of the smear block 21, and the wheel core direction of the roller 62 is perpendicular to the moving direction of the cardboard. Before the gluing area of ​​the cardboard reaches the smear block 21, the roller 62 supports the cardboard to ensure that the gluing area of ​​the cardboard is in stable contact with the bristles 24. A pressing assembly 70 is also provided on the workbench 12 to ensure that the gluing area of ​​the cardboard is in contact with the bristles 24. The pressing assembly 70 includes a support plate 71 arranged on the workbench 12, and a top plate 72 is suspended above the smear head on the support plate 71. Two cylinders 73 with downward openings are arranged at intervals on the top of the top plate 72. A vertically arranged slide bar 74 is slidably arranged on the cylinder 73. The lower ends of the two slide bars 74 pass through the top plate 72 and are jointly provided with a mounting frame 75, so that the mounting frame 75 can be raised and lowered. Two rubber wheels 78 arranged at intervals are rotatably arranged on the mounting frame 75, and the wheel core direction of the rubber wheel 78 is perpendicular to the moving direction of the cardboard. A baffle 76 is arranged on the lower part of the rod body of the slide rod 74 between the bottom of the cylinder 73 and the top plate 72, and a compression spring 77 is sleeved on the rod body of the slide rod 74 between the baffle 76 and the top of the cylinder 73. When the cardboard passes through the smearing block 21, the rubber wheel 78 provides downward pressure to ensure that the glue-coated area of ​​the cardboard contacts the bristles 24. By using the baffle 76 and the compression spring 77, the rubber wheel 78 can adapt to cardboards of different thicknesses. When a thicker cardboard passes, the rubber wheel 78 is pushed upward by the cardboard, and the compression spring 77 is compressed to avoid the rubber wheel 78 from being in the same position and causing damage to the cardboard. One of the rubber wheels 78 is located above the roller 62 to ensure that the cardboard smearing area remains stable before contacting the smearing block 21. The other rubber wheel 78 is located above the smearing block 21 to provide downward pressure to facilitate the glue to be evenly applied to the cardboard smearing area.

[0031] The use principle of a carton gluing machine with uniform gluing in this embodiment is as follows: the cardboard is conveyed to the folding mechanism 2 by the paper feeding mechanism 1, and the gluing area of ​​the cardboard will pass through the gluing mechanism 10 during the conveying process. The driving motor 41 is started to drive the rotating shaft 42 to rotate, driving the first driving wheel 43 and the second driving wheel 81 to rotate. The second driving wheel 81 rotates to drive the second driven wheel 82 and the third driving wheel 83 to rotate, thereby driving the third driven wheel 85 and the rotating block 53 to rotate, so that the threaded rod 52, the connecting rod 51, and the push plate 32 rise, and the glue in the glue box 30 is squeezed upward. The rubber wheel 78 presses the gluing area of ​​the cardboard downward, so that the glue is discharged from the glue outlet 22 through the discharge pipe 31 and the rotating pipe 20 and adheres to the gluing area of ​​the cardboard; at the same time, the first driving wheel 43 rotates to drive the first driven wheel 44, the rotating pipe 20, the smearing block 21, and the bristles 24 to rotate, and the glue squeezed into the gluing area of ​​the cardboard is scattered, ensuring that the glue is evenly smeared on the gluing area of ​​the cardboard, and ensuring the firmness of the subsequent cardboard adhesion.
