Description

Technical Field

[0001] This application relates to the field of paper boxes, and in particular to a high-efficiency paper box gluing machine. Background Technology

[0002] In the packaging and printing industry, the application of a cardboard box gluing machine is the final step in packaging box processing. It folds and glues the printed and die-cut cardboard into shape. Machine gluing replaces manual gluing, reducing labor costs and improving efficiency.

[0003] Currently, Chinese utility model patent CN218615669U discloses a fully automatic gluing and folding box device. The device has a transmission belt on the bottom surface, an electric telescopic rod on the top surface of the transmission belt, a load-bearing frame on the bottom surface of the electric telescopic rod, support rods connecting the load-bearing frames, a second electric telescopic rod on the side of the electric telescopic rod, a positioning plate on the bottom surface of the second electric telescopic rod, an adhesive tube between the load-bearing frames, an adhesive tube with a dispensing pipe, suction pumps at both ends of the adhesive tube, and a conduit on the top surface of the suction pump. This patent has the effect of reducing the blockage of the conical tube.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: the paper boxes are of different sizes, and the gluing positions are different, making them unsuitable for paper boxes of different sizes. Summary of the Invention

[0005] In order to accommodate paper boxes of different sizes and expand the application range of the paper box gluing machine, this application provides a high-efficiency paper box gluing machine.

[0006] This application provides a high-efficiency paper box gluing machine, which adopts the following technical solution:

[0007] A high-efficiency paper box gluing machine includes a frame, a transmission device, a creasing device, a gluing device, a folding device, and an alignment device. The transmission device is mounted on the frame. The gluing device includes a gluing assembly, which comprises a sensor, a cylinder, a roller, a glue box, and a glue-adding assembly for adding glue to the glue box. The cylinder is slidably connected to the frame along a direction perpendicular to the movement direction of the transmission belt assembly. The axial direction of the roller is parallel to the sliding direction of the cylinder. The roller is rotatably connected to the piston rod of the cylinder. The glue box is mounted on the piston rod of the cylinder. The sidewall of the roller abuts against the inner sidewall of the glue box. The glue-adding assembly is used to add glue into the glue box. The sensor is mounted on the frame.

[0008] By adopting the above technical solution, the cylinder can move laterally relative to the transmission belt, thereby changing the position of the rollers on the cylinder used to adhere the glue to the cardboard box. When the cardboard comes over, the sensor senses the cardboard, and the cylinder drives the rollers to abut against the cardboard. As the transmission belt drives the cardboard to move, the cardboard moves relative to the rollers, adhering the glue on the rollers to the cardboard box. This allows the cardboard box gluing machine to adapt to the gluing part of different sized cardboard boxes by moving the position of the cylinder when gluing is required, thus expanding the application range of the cardboard box gluing machine.

[0009] Optionally, the glue-adding assembly includes a feeding tank, a first feeding tube, and a second feeding tube. The feeding tank is disposed on the cylinder body of the cylinder. The first feeding tube is disposed on the lower end face of the feeding tank and faces the glue box. The first feeding tube is connected to the interior of the feeding tank. The second feeding tube is slidably connected to the inner side wall of the first feeding tube. Both ends of the second feeding tube are sealed. An abutment block is provided at the upper end of the second feeding tube, and the cross-sectional area of ​​the abutment block is larger than the inner diameter of the first feeding tube. The second feeding tube has a connecting hole and an outflow hole. The connecting hole and the outflow hole are disposed on the side wall of the second feeding tube, and the height of the connecting hole is higher than that of the outflow hole.

[0010] By adopting the above technical solution, when the cardboard passes through the cylinder and the sensor no longer detects the cardboard, the piston rod of the cylinder retracts, the inner bottom wall of the glue box abuts against the lower end face of the second feeding tube and drives the second feeding tube to move upward. The connecting hole exposes the first feeding tube and connects with the feeding bucket. The glue in the feeding bucket enters the second feeding tube through the connecting hole and enters the glue box through the outflow hole. When the sensor detects the cardboard again, the piston rod of the cylinder descends, the second feeding tube moves downward, and the connecting hole enters the first feeding tube, thus achieving the sealing of the adding component. The adding component has a simple structure, can be added as needed, and requires no personnel supervision.

[0011] Optionally, the transmission device includes four transmission belts, namely a first transmission belt, a second transmission belt, a third transmission belt, and a fourth transmission belt. The first transmission belt, the second transmission belt, the third transmission belt, and the fourth transmission belt are connected end-to-end in sequence and are perpendicular to each other, forming a "U" shape. The indentation device includes two indentation components, which are respectively located on the first transmission belt and the second transmission belt. The alignment device includes four alignment components, which correspond one-to-one with the four transmission belts. The folding device includes a first folding component and a second folding component. The first folding component is positioned above the third transmission belt, and the second folding component is positioned above the fourth transmission belt. The gluing device includes two gluing components, which are respectively positioned above the second transmission belt and the third transmission belt.

[0012] By adopting the above technical solution, the four transmission belts are arranged in a U-shape, which occupies a small area and has the inlet and outlet close together, making it convenient for personnel to supervise. The operator first places the cardboard on the first transmission belt. The cardboard passes through the alignment component and then through the creasing component, which presses horizontal creases into the cardboard. The cardboard then enters the second transmission belt, passes through the alignment component on the second transmission belt, and then through the creasing component. Since the first and second transmission belts are perpendicular to each other, after passing through the creasing component, the cardboard has vertical creases pressed into it. The gluing component then applies glue to the pasting part of the cardboard. The cardboard then passes through the third transmission belt, which folds the cardboard into a square shape through the folding component and applies glue to the bottom of the cardboard. The cardboard then enters the fourth transmission belt, which seals the bottom of the cardboard through the folding component. The orientation of the cardboard does not change on the equipment. It is only through the transmission between the transmission belts that different components on each transmission belt complete the corresponding operations to glue the cardboard into a cardboard box. This equipment is easy to operate.

[0013] Optionally, the alignment assembly includes two abutment plates, two racks, a gear, and a drive motor. The abutment plates are slidably connected to the frame along a direction perpendicular to the movement direction of the corresponding transmission belt. The abutment plates are provided with guide plates to facilitate the cardboard entering between the two abutment plates. The two racks correspond one-to-one with the two abutment plates, and the length direction of the racks is parallel to the sliding direction of the abutment plates. The gear is located between the two racks and meshes with the two racks. The drive motor is mounted on the frame and is used to drive the gear to rotate.

[0014] By adopting the above technical solution, the cardboard on the conveyor belt is guided by the guide plate, and the two ends of the cardboard abut against the opposite side walls of the two abutment plates. The guide component makes it easy to align the position of the cardboard, which is convenient for subsequent operations. When the size of the cardboard changes, the operator can start the drive motor. The drive motor rotates and drives the gear to rotate. The gear rotates and drives the two racks to move relative to each other. The racks drive the abutment plates to move closer or further apart, realizing the alignment of different cardboards. The alignment component has a simple structure and is easy for the operator to adjust.

[0015] Optionally, the indentation assembly includes an indentation frame, four indentation wheels, four sliding blocks, a rotating roller, and a driving component. The indentation frame is mounted on the machine frame. The length direction of the rotating roller is parallel to the length direction of the corresponding transmission belt. The rotating roller is rotatably connected to the indentation frame. The sliding blocks are slidably connected to the indentation frame along the length direction of the rotating roller. The four indentation wheels correspond one-to-one with the four sliding blocks. The indentation wheels are rotatably connected to the sliding blocks and slidably connected to the rotating rollers. The driving component includes a first bevel gear, a second bevel gear, and a drive motor. The first bevel gear is mounted on one end of the rotating roller, and the second bevel gear is mounted on the output shaft of the drive motor. The second bevel gear meshes with the first bevel gear.

[0016] By adopting the above technical solution, the output shaft of the motor drives the second bevel gear to rotate, the second bevel gear drives the first bevel gear to rotate, the first bevel gear drives the rotating roller to rotate, and the rotating roller drives the creasing wheel to rotate. When the cardboard passes through the creasing assembly, the distance between the creasing wheel and the transmission belt is less than the thickness of the cardboard. The creasing wheel presses indentations on the cardboard to facilitate subsequent folding of the cardboard. The driving component facilitates the cardboard to detach from the creasing assembly, and the cardboard is not easily jammed by the creasing wheel. When the size of the cardboard changes, the operator can change the distance between the creasing wheels by sliding the sliding block to adapt to different cardboard sizes. The creasing assembly is suitable for cardboard of different sizes, thus improving its applicability.

[0017] Optionally, the first folding assembly includes four first folding blocks and a first pressure plate. The first folding blocks have guide slopes to facilitate folding of cardboard with creases. The first folding blocks are slidably connected to the frame along the direction of movement perpendicular to the corresponding transmission belt. The four first folding blocks are distributed along the length direction of the corresponding transmission belt. The first pressure plate is slidably connected to the frame along the sliding direction parallel to the first folding blocks.

[0018] By adopting the above technical solution, when the cardboard passes through the first folding assembly, the first pressure plate presses one end of the cardboard onto the transmission belt, and the other end of the cardboard is folded sequentially according to the creases. The guide slope facilitates the folding of the cardboard. There are four folding blocks distributed along the length direction. The folding blocks fold the cardboard into a square tube shape and stick the adhesive part to the inner wall of the cardboard. When the size of the cardboard changes, the operator can slide the first pressure plate and the first folding blocks to adapt to cardboard of different sizes, thereby improving the applicability of the first folding assembly.

[0019] Optionally, the second folding assembly includes a second folding block and a pressing member for reducing the movement of the square tube-shaped cardboard corresponding to the drive belt. The second folding block has a guide slope to facilitate folding of the cardboard with creases. The second folding block is slidably connected to the frame along a direction perpendicular to the movement direction of the corresponding drive belt.

[0020] By adopting the above technical solution, when the cardboard passes through the second folding assembly, the second pressure plate presses the square-shaped cardboard onto the conveyor belt. The end of the cardboard with glue is folded along the crease and adheres to the bottom of the square barrel. The guide slope facilitates the folding of the cardboard. The operator can move the pressing box and the second folding block to adapt the second folding block and the pressing box to cardboard of different sizes, thereby improving the applicability of the second folding assembly.

[0021] Optionally, the frame is further provided with a linkage assembly, which includes four first linkage rods, second linkage rods, third linkage rods, and fourth linkage rods. The four first linkage rods correspond one-to-one with the four sliding blocks of the indentation assembly on the first transmission belt. One end of the first linkage rod is disposed on the corresponding sliding block, and the other end of the four first linkage rods is disposed on the four first folding blocks respectively. One end of the second linkage rod is disposed on the second folding block, and the other end of the second linkage rod is disposed on the sliding block of the corresponding indentation assembly on the second transmission belt that is furthest from the second folding block. One end of the third linkage rod is disposed on the cylinder in the glue application assembly corresponding to the third transmission belt, and the other end of the third linkage rod is disposed on the sliding block of the corresponding indentation assembly on the first transmission belt that is furthest from the corresponding cylinder. One end of the fourth linkage rod is disposed on the cylinder in the corresponding glue application assembly on the second transmission belt, and the other end of the fourth linkage rod is disposed on the sliding block corresponding to the indentation assembly on the second transmission belt.

[0022] By adopting the above technical solution, when the operator needs to adjust the indentation wheel on the first transmission belt, the operator will adjust the sliding block. Since the first and third transmission belts are parallel to each other, the corresponding first folding block on the third transmission belt will change accordingly. When the indentation wheel moves, the corresponding first folding block will also move the same distance. When the sliding block moves, the sliding block drives the third linkage rod to move, and the third linkage rod drives the cylinder on the third transmission belt to move. Only the sliding block on the first transmission belt needs to be adjusted to complete the adjustment of the relevant structure, which is simple. When the operator needs to adjust the indentation wheel on the second transmission belt, the operator will adjust the corresponding sliding block. Since the second and fourth transmission belts are parallel, when adjusting the sliding block furthest from the second folding block, the second folding block will also move accordingly through the second linkage rod. When the sliding block on the second transmission belt moves, the sliding block drives the fourth linkage rod to move, and the fourth linkage rod drives the cylinder on the second transmission belt to move. Only the sliding block on the second transmission belt needs to be adjusted to complete the adjustment of the relevant structure, which is simple and convenient.

[0023] Optionally, the frame is provided with three pushing assemblies, each including a pushing cylinder and a push plate. The pushing assemblies are located at the end connection of two adjacent transmission belts. The length direction of the pushing cylinder is parallel to the length direction of the rearmost transmission belt among the connected transmission belts. The push plate is disposed on the piston rod of the pushing cylinder.

[0024] By adopting the above technical solution, when the cardboard enters the transmission belt between the transmission belts, the piston rod of the cylinder is pushed to extend, transferring the cardboard from the previous transmission belt to the next transmission belt. The push assembly has a simple structure, which facilitates the linkage of the equipment and improves the continuity of the equipment.

[0025] Optionally, the pressing component includes a pressing frame, a sliding plate, a fixed plate, a sliding rod, a pressure plate, and a connecting rod. The sliding plate is slidably connected to the side wall of the first linkage rod closest to the fourth transmission belt. The sliding plate slides along a direction perpendicular to the movement of the fourth transmission belt. The fixed plate is connected to the first folding block. The sliding plate has an inclined groove. The fixed plate has an inclined strip that cooperates with the inclined groove. The inclined strip is slidably connected in the inclined groove. The pressing frame is mounted on the frame. The sliding rod slides vertically and is connected to the pressing frame. The pressure plate is mounted on the sliding rod. The connecting rod is mounted on the sliding plate. The connecting rod has an inclined surface for changing the height of the sliding plate.

[0026] By adopting the above technical solution, when the height of the cardboard box changes, the dimensions of each side of the cardboard box change, and the sliding blocks on the first transmission belt move relative to each other, causing the first linkage rods to move relative to each other. After the first linkage rods move, the fixed plate and the sliding plate change. The inclined groove and the inclined bar cooperate to make the sliding plate move along the direction of the first transmission belt. The sliding plate drives the connecting rod to move, and the position of the pressure plate against the inclined surface changes, thereby changing the height of the pressure plate. The change in the height of the sliding rod changes the height of the sliding rod against the box body. The position of the pressing component can be adjusted by only adjusting the sliding block, which is simple to operate.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] The gluing device is used for gluing cardboard of different sizes;

[0029] The folding assembly is used to fold the cardboard sequentially and adhere the adhesive.

[0030] The linkage assembly is used for the linkage of the indentation device, the gluing device, and the folding device. Attached Figure Description

The upper end face of the connecting rod and the end away from the second transmission belt 23 are provided with an inclined surface 861. The lower end face of the pressing plate 85 abuts against the inclined surface 861.

[0048] The implementation principle of an efficient paper box gluing machine according to this application embodiment is as follows: the operator first measures the size of the paper box, adjusts the distance between the creasing rollers 312 in the creasing assembly 31 according to the size of the paper box, and moves the sliding block 313 to adjust the distance between the creasing rollers 312.

[0049] When the worker adjusts the creasing roller 312 corresponding to the first transmission belt 22, the sliding block 313 drives the first linkage rod 91 to move, and the first linkage rod 91 drives the first folding block 511 to move. The distance between two adjacent creasing rollers 312 is the width of the cardboard box surface, and the distance between two adjacent creasing rollers 312 is the distance between two adjacent sliding blocks 313 along the width direction of the third transmission belt 24. The sliding block 313 furthest from the third transmission belt 24 is linked to the mounting block 417 of the first gluing assembly 41 through the third linkage rod 93. When the first transmission belt 22 is adjusted, the sliding block 313 moves along the width direction of the third transmission belt 24. After the sliding block 313 of the moving belt 22 is adjusted, the first folding block 511 on the third transmission belt 24 is also adjusted, as is the gluing assembly 41 on the first transmission belt 22. Due to the different widths of the cardboard boxes, the distance between the first linkage rods 91 changes. The sliding plate 82 moves along the length of the first transmission belt 22 under the cooperation of the sliding groove and the sliding strip. The sliding plate 82 drives the connecting rod to move, and the contact position between the inclined surface 861 on the connecting rod and the pressure plate 85 changes. The change in the height of the sliding rod 84 causes the height of the pressure plate 87 to change.

[0050] Then, the staff adjusts the corresponding indentation wheel 312 on the second transmission belt 23. The sliding block 313 drives the second linkage rod 92 to move, and the second linkage rod 92 drives the second folding block 521 to move. The sliding block 313 also drives the mounting block 417 of the corresponding glue application component 41 on the second transmission belt 23 to be connected through the fourth transmission belt 25. When the distance between the sliding blocks 313 on the second transmission belt 23 is adjusted and the glue application component 41 on the second transmission belt 23 is adjusted, the second folding block 521 on the fourth transmission belt 25 is also adjusted.

[0051] After the adjustment is completed, the staff places the cardboard on the first transmission belt 22 of the equipment. Guided by the guide plate 615, the cardboard enters between the two abutment plates 611. Then, guided by the abutment plates 611, it enters the creasing assembly 31, which first presses out a horizontal crease on the cardboard. After the cardboard leaves the first transmission belt 22, the piston rod of the push cylinder 71 located between the first transmission belt 22 and the second transmission belt 23 extends, pushing the push plate 72 on the push cylinder 71 to push the cardboard onto the second transmission belt 23.

[0052] Guided by the alignment component 61, the cardboard enters the creasing component 31 of the second transmission belt 23, and longitudinal creases are pressed into the cardboard. Then, the second transmission belt 23 sends the cardboard to the gluing device 4. After the sensor 411 senses the cardboard, the piston rod of the cylinder 412 extends, and the roller 413 abuts against the cardboard. The roller 413 rotates to deliver the glue in the glue box 414 to the cardboard. When the cardboard leaves the gluing device 4, the piston rod of the cylinder 412 retracts, and the bottom wall of the glue box 414 abuts against the second feeding pipe 44 and rises vertically. The glue in the feeding barrel 42 enters the second feeding pipe 44 through the connecting hole 46 and finally enters the glue box 414 through the outflow hole 47.

[0053] After the cardboard passes through the second transmission belt 23, the piston rod of the push cylinder 71 located between the second transmission belt 23 and the third transmission belt 24 extends. The push plate 72 of the alignment cylinder 412 pushes the cardboard onto the third transmission belt 24. Guided by the alignment component 61, the third transmission belt 24 delivers the cardboard to the gluing device 4. After the sensor 411 detects the cardboard, the piston rod of the cylinder 412 extends, and the roller 413 abuts against the cardboard. The roller 413 rotates to deliver the glue in the glue box 414 to the glue application device 4. On the cardboard, after the cardboard leaves the gluing device 4, the piston rod of the cylinder 412 retracts, and the bottom wall of the glue box 414 rises vertically against the second feeding tube 44. The glue in the feeding barrel 42 enters the second feeding tube 44 through the connecting hole 46 and finally enters the glue box 414 through the outflow hole 47. Then it enters the first folding assembly 51 of the third transmission belt 24. As the cardboard moves on the third transmission belt 24, the cardboard is folded sequentially according to the transverse creases until it is folded into a square tube.

[0054] After the square tube cardboard leaves the third drive belt 24, the piston rod of the push cylinder 71 located between the third drive belt 24 and the fourth drive belt 25 extends, and the push plate 72 aligned with the cylinder 412 pushes the cardboard onto the fourth drive belt 25. Under the guidance of the alignment component 61, the cardboard enters the second folding component 52, and the pressing plate 87 abuts against the upper end face of the square tube cardboard. Then, the second folding block 521 folds the bottom of the square tube cardboard and adheres it to the cardboard to form an open cardboard box. Then, the open cardboard box is sent out of the equipment during the transport of the fourth drive belt 25.

[0055] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
