Description

Technical Field

[0001] This utility model relates to the field of paper box forming machine technology, and in particular to an automatic paper box pasting, covering and folding device. Background Technology

[0002] Currently, the blank boxes used for forming paper boxes (such as top and bottom shoe boxes, shirt boxes, gift boxes, mobile phone boxes, etc.) are first die-cut from gray cardboard, conveyed, and glued at the four corners. Then, the blank box and the face paper (with glued face paper underneath the blank box) are positioned and glued. Finally, the blank box is conveyed to the pasting and forming mechanism by the picking mechanism and the feeding mechanism to be pasted to form the finished paper box.

[0003] In existing technology, one type of pasting mechanism includes a tray for supporting the cardboard box and two sets of pasting mechanisms for brushing the wide and long sides of the cardboard box respectively. Each set of pasting mechanisms has the same structure, including a mounting base and a roller, a folding brush, a folding knife, and a pressing plate arranged sequentially on the mounting base. The roller is used to brush the face paper onto the outer surface of the blank box, the folding knife folds the upper end of the face paper into the blank box, and the pressing plate presses the pasted face paper firmly. However, in this type of pasting mechanism, the wide-side folding knife and the long-side folding knife are located at the same height. When pasting blank boxes of different sizes, the folding knife needs to be replaced, which is inconvenient to use. Another type of pasting mechanism has a roller, folding knife, pre-pressing plate, folding brush, and pressing plate arranged sequentially on the long-side mounting base. This results in a complex overall structure of the pasting mechanism and requires a large space. Utility Model Content

[0004] The purpose of this utility model is to overcome the defects of the prior art. This utility model provides an automatic paper box pasting, covering and folding device. The folding knife is placed below the glue roller brush. The wide-side folding knife and the long-side folding knife are arranged at different heights. When processing blank boxes of different sizes, there is no need to change the folding knife, which is convenient and efficient. At the same time, the overall structure of the pasting mechanism is simple and occupies little space.

[0005] The technical solution of this utility model: An automatic paper box pasting, covering, and folding device, including a worktable, a box holder, and two long-side pasting mechanisms and two wide-side pasting mechanisms disposed on the worktable. The worktable has through holes for the box holder to enter and exit the worktable. Each of the two long-side pasting mechanisms includes a long-side base and a long-side glue roller brush and a long-side folding knife disposed on the long-side base. The two long-side bases are offset relative to the box holder, with the long-side folding knife located below the long-side glue roller brush. Each of the two wide-side pasting mechanisms includes a wide-side base and a wide-side glue roller brush and a wide-side folding knife disposed on the wide-side base. The base body is offset relative to the tray seat. The wide-edge folding knife is located below the wide-edge glue roller brush. The long-edge base body or the wide-edge base body is provided with two folding ear brushes. The long-edge glue roller brush and the wide-edge glue roller brush, as well as the long-edge folding knife and the wide-edge folding knife, are all arranged at different heights. The lower ends of the two long-edge base bodies and the two wide-edge base bodies are provided with long-edge pressing plates and wide-edge pressing plates at the same height. The two long-edge pressing plates and the two wide-edge pressing plates enclose and form a pressing area that is adapted to the paper box. Each pressing plate is slidably arranged relative to the corresponding base body to adjust the size of the pressing area. The tray seat stops at the long-edge pasting mechanism and the wide-edge pasting mechanism.

[0006] Using the above technical solution, the pre-made box and the face paper are placed on the tray. The tray moves up and down relative to the mounting mechanism. During the downward movement of the tray, the long-side glue roller brush adheres to the long side of the face paper and presses it against the long side wall of the pre-made box from bottom to top. Then, the long-side folding knife folds the upper end of the face paper into the inner wall of the pre-made box. The folding ear brush folds the two sides of the face paper towards the wide side of the pre-made box. The tray continues to move down, and the wide-side glue roller brush adheres to the wide side of the face paper and presses it against the wide side wall of the pre-made box from bottom to top. The wide-side folding knife folds the upper end of the face paper into the inner wall of the pre-made box. The pressing plate moves towards the pre-made box, improving the adhesion between the face paper and the pre-made box. The height allows air bubbles to be squeezed out, making the face paper more secure. Then, the pressing plate moves backward, the tray rises, and the cardboard box is unloaded. At the same time, another set of blank boxes and face paper are sent to the tray. This process is repeated. The relatively staggered arrangement of the trays allows the pressing plate to slide on the tray. The position of the pressing plate can be adjusted according to the size of the blank box to be pasted. The pressing plates do not interfere with each other when moving towards the blank box, eliminating the need to replace the pressing plates or the entire machine. This makes it more practical and the adjustment is convenient and quick. The long-side folding blades and wide-side folding blades are staggered in height, so they do not interfere with each other when folding the face paper into the blank box. When processing blank boxes of different sizes, there is no need to change the folding blades.

[0007] Further features of this invention: The long side base is provided with a first driving component for driving the two long side rubber rollers to move towards each other or away from each other, and a second driving component for driving the two long side folding blades to move towards each other or away from each other; the wide side base is provided with a third driving component for driving the two wide side rubber rollers to move towards each other or away from each other, and a fourth driving component for driving the two wide side folding blades to move towards each other or away from each other.

[0008] Further configuration: The first and third drive components have the same structure, both including a roller brush mounting frame and two first drive components. The two ends of the long-side rubber roller brush are mounted on the roller brush mounting frame, and the two first drive components are connected to the roller brush mounting frame to drive the rubber roller brush to move. The second and fourth drive components have the same structure, both including a folding knife seat and a second drive component. The folding knife is mounted and fixed on the folding knife seat, and the second drive component is connected to the folding knife seat to drive the folding knife to move.

[0009] With the above-mentioned further settings, the distance between the two glue rollers can be adjusted by moving the drive roller brush mounting frame, and the distance between the glue roller brush and the blank box can also be adjusted, so that the glue roller brush and the blank box have good fit. The movement of the folding knife seat drives the folding knife to work, folding the upper end of the face paper from vertical to horizontal, so that the face paper can adhere to the inner side wall of the blank box and the pasting is complete.

[0010] A further feature of this invention is that a support guide rail is provided on the long side seat or the wide side seat, and folding ear sliders are provided at both ends of the support guide rail. Each of the two folding ear sliders is provided with a third driving component, and the two folding ear brushes are connected to the output shaft of the third driving component so that the paper is folded relative to the paper box under the action of the third driving component.

[0011] With the above-mentioned further configuration, the folding ear slider can slide on the support guide rail, and the distance between the two folding ears can be adjusted according to the size of the blank box to accommodate blank boxes of different sizes. The third driving component drives the folding ear brush to fold the two sides of the face paper.

[0012] A further feature of this invention includes a pressing assembly positioned opposite the tray base. This pressing assembly comprises a pressing plate, a pressure plate, a first module that drives the pressing plate and pressure plate to move synchronously up and down, and a second module that drives the pressing plate to move up and down relative to the pressure plate. The first module includes a main slide rod, a first motor, a lifting gear, and a lifting rack. The lifting gear is mounted on the output shaft of the first motor, and the lifting rack is fixed to the main slide rod and meshes with the lifting gear, so that the main slide rod moves up and down when the lifting gear rotates. The pressure plate is located at the end of the main slide rod. The second module is located at the upper end of the main slide rod. The second module includes a second motor, a lead screw, and a nut. The second motor is connected to the lead screw to drive the lead screw to rotate, and the nut is threadedly engaged with the lead screw. The nut is connected to the pressing plate via a connecting rod to drive the pressing plate to move up and down relative to the pressure plate.

[0013] With the above-mentioned further configuration, after the blank box and face paper are placed on the tray, the pressure plate and the backing plate move down. The backing plate presses against the inner bottom wall of the blank box, cooperating with the tray to clamp the blank box, so that the blank box will not shift when the tray moves up and down, and the face paper is accurately positioned when pasted. Before the folding knife folds the face paper into the blank box, the pressure plate moves up. After the folding knife works, the pressure plate moves down, so that the face paper adheres to the inner wall of the blank box, resulting in a good pasting effect between the face paper and the blank box.

[0014] A further feature of this invention is that a T-shaped pre-pressing plate is provided on the two long or wide sides of the base, the pre-pressing plate being located between the folding knife and the ear brush, and the two ear brushes being located on both sides of the vertical part of the pre-pressing plate.

[0015] With the above-mentioned further configuration, after the first mounting, the face paper can be squeezed by the pre-press plate to ensure good adhesion between the face paper and the blank box. The pre-press plate is T-shaped, and the folding brushes are located on both sides of the vertical part of the pre-press plate, which will not excessively increase the space occupied by the mounting mechanism and make reasonable use of the space.

[0029] like Figure 1-8As shown, an automatic paper box pasting, covering, and folding device includes a worktable 2, a box holder 4, and two long-side pasting mechanisms 5 and two wide-side pasting mechanisms 6 mounted on the worktable 2. The worktable 2 has through holes for the box holder 4 to enter and exit the worktable 2. Each of the two long-side pasting mechanisms 5 includes a long-side base 51 and a long-side glue roller brush 52 and a long-side folding blade 53 mounted on the long-side base 51. The two long-side bases 51 are offset relative to the box holder 4, and the long-side folding blade 53 is located below the long-side glue roller brush 52. Each of the two wide-side pasting mechanisms 6 includes a wide-side base 61 and a wide-side glue roller brush 62 and a wide-side folding blade 63 mounted on the wide-side base 61. The two wide-side pasting bases are offset relative to the box holder 4, that is, the center lines of the bases are not on the same straight line. The wide-side folding blade 63 is located below the box holder 4. Below the wide-edge glue roller brush 62, two folding brushes 7 are provided on the long-edge seat 51 or the wide-edge seat 61. The long-edge glue roller brush 52, the wide-edge glue roller brush 62, the long-edge folding blade 53, and the wide-edge folding blade 63 are all staggered in height. If the long-edge is pasted first, the long-edge pasting mechanism 5 is located above the wide-edge pasting mechanism 6, and the folding brushes 7 are located on the long-edge seat 51. If the wide-edge is pasted first, the wide-edge pasting mechanism 6 is located above the long-edge pasting mechanism 5, and the folding brushes 7 are located on the wide-edge seat 61. The lower ends of the two long-edge seats 51 and the two wide-edge seats 61 are provided with long-edge pressing plates 54 and wide-edge pressing plates 64 at the same height. The two long-edge pressing plates 54 and the two wide-edge pressing plates 64 enclose and form a pressing area 100 that is adapted to the cardboard box. Each pressing plate is corresponding to the other. The seat body is slidably set to adjust the size of the pressing area 100. The tray seat 4 stops at the long side pasting mechanism 5 and the wide side pasting mechanism 6. The blank box 200 and the face paper are placed on the tray seat 4. The tray seat 4 will move up and down relative to the pasting mechanism. During the downward movement of the tray seat 4, the long side glue roller brush 52 is attached to the long side of the face paper and presses the face paper to the long side wall of the outer side of the blank box 200 from bottom to top. Then, the long side folding knife 53 folds the upper end of the face paper into the inner wall of the blank box 200. The folding ear brush 7 folds the two sides of the face paper towards the wide side of the blank box 200. The tray seat 4 continues to move down. The wide side glue roller brush 62 is attached to the wide side of the face paper and presses the face paper to the wide side wall of the outer side of the blank box 200 from bottom to top. The wide side folding knife 63 folds the upper end of the face paper into the inner wall of the blank box 200. The pressing plate moves towards the blank box 200, ensuring a high degree of adhesion between the face paper and the blank box 200, and also squeezing out air bubbles, making the face paper more secure. Then, the pressing plate moves backward, and the box holder 4 rises, unloading the paper box. At the same time, another set of blank boxes 200 and face paper are sent to the box holder 4. This process is repeated. The relatively staggered seats allow the pressing plate to slide on the seats, and its position can be adjusted according to the size of the blank box 200 to be pasted. The pressing plates do not interfere with each other when moving towards the blank box 200, eliminating the need to replace the pressing plates or the entire machine, making it more practical and convenient to adjust. The long-side folding blade 53 and the wide-side folding blade 63 are staggered in height, ensuring they do not interfere with each other when folding the face paper into the blank box 200. This is suitable for processing blank boxes 200 of different sizes.No need to replace the folding blade; a brush layer can be installed on the rubber roller brush, allowing it to roll and brush the face paper as it rotates. This prevents the face paper from being directly in contact with the rubber roller brush and being "teared" by excessive friction, achieving elastic contact with the face paper. It also ensures the face paper is evenly and smoothly lifted, preventing wrinkles. The worktable is also equipped with a drive structure that drives the horizontal sliding of each seat. The drive structure can use a motor, lead screw, and nut to drive the seats to move in opposite directions or in opposite directions, controlling the feed of the seats.

[0030] The long-side base 51 is provided with a first driving component that drives the two long-side rubber roller brushes 52 to move towards each other or away from each other, and a second driving component that drives the two long-side folding blades 53 to move towards each other or away from each other. The wide-side base 61 is provided with a third driving component that drives the two wide-side rubber roller brushes 62 to move towards each other or away from each other, and a fourth driving component that drives the two wide-side folding blades 63 to move towards each other or away from each other. The first driving component and the third driving component have the same structure, both including a roller brush mounting frame 551 and two first driving members 552. Each driving member can be a cylinder, an electric cylinder, or a motor, etc. In this utility model, except for the second driving member 562, the other driving members are preferably set with cylinders, which can quickly drive the corresponding parts to slide. The two ends of the long-side rubber roller brushes 52 are mounted on the roller brush mounting frame 551, and the two first driving members 552 are connected to the roller brush mounting frame 551 to drive the rubber roller brushes to move. The second driving component and the fourth driving component have the same structure, both including a folding blade seat 561. The second driving component 562 is connected to the folding knife base 561, and the folding knife is fixedly mounted on the folding knife base 561 to drive the folding knife to move. By moving the roller brush mounting bracket 551, the distance between the two rubber roller brushes can be adjusted, and the distance between the rubber roller brushes and the blank box 200 can be adjusted to ensure good fit between the rubber roller brushes and the blank box 200. The movement of the folding knife base 561 drives the folding knife to work, folding the upper end of the face paper from vertical to horizontal, so that the face paper can adhere. On the inner wall of the blank box 200, the paper is completely pasted. Guide rods 563 can be connected to both the roller brush mounting frame 551 and the folding knife seat 561. The seat body is provided with a guide seat 564. The guide rod 563 slides on the guide seat 564, so that the roller brush mounting frame and the folding knife seat 561 have good stability and do not deviate when sliding. The second driving component 562 can be a motor. The motor is eccentrically connected to a transmission shaft 565. The transmission shaft 565 is connected to the guide rod 563, which converts the rotational motion into linear reciprocating motion.

[0031] The long side seat 51 or the wide side seat 61 is provided with a support guide rail 57. The two ends of the support guide rail 57 are provided with folding ear sliders 571. Each of the two folding ear sliders 571 is provided with a third driving member 572. The two folding ear brushes 7 are connected to the output shaft of the third driving member 572 so that they slide relative to the paper box under the action of the third driving member 572 to perform folding ear operation on the paper. The folding ear sliders 571 can slide on the support guide rail 57. The distance between the two folding ears can be adjusted according to the size of the blank box 200 so as to cover blank boxes 200 of different sizes. The third driving member 572 drives the folding ear brushes 7 to move and fold the two sides of the paper. A sensor 573 can also be provided on the folding ear sliders 571 to monitor the position of the folding ear brushes 7. After the sensor 573 detects the folding ear brushes 7, the third driving member 572 stops working.

[0032] A pressing assembly 9 is also provided opposite to the tray seat 4. Specifically, the pressing assembly 9 can be set on the frame of the entire equipment (the frame is not shown in the figure). The pressing assembly 9 includes a pressing plate 91, a pressing plate 92, a first module 93 that drives the pressing plate 91 and the pressing plate 92 to move up and down synchronously, and a second module 94 that drives the pressing plate 91 to move up and down relative to the pressing plate 92. The first module 93 includes a main slide rod 931, a first motor 932, a lifting gear 933, and a lifting rack 934. The lifting gear 933 is located on the output shaft of the first motor 932, and the lifting rack 934 is fixed to the main slide rod 931 and meshes with the lifting gear 933 so that the main slide rod 931 moves up and down when the lifting gear 933 rotates. The pressing plate 92 is located at the end of the main slide rod 931, and the second module 94 is located at the upper end of the main slide rod 931. The second module 94 includes a second motor 941, a lead screw 942, and a nut 943. The second motor 941 is connected to the lead screw 942 to drive the lead screw 942 to rotate. The nut 943 is threadedly engaged with the lead screw 942. The nut 943 is connected to the pressure plate 91 through a connecting rod to drive the pressure plate 91 to move up and down relative to the pressure plate 92. After the blank box 200 and the face paper are placed in the tray seat 4, the pressure plate 91 and the pressure plate... 92 moves down, and the pressure plate 92 presses against the inner bottom wall of the blank box 200, cooperating with the box holder 4 to clamp the blank box 200, so that the blank box 200 will not move when the box holder 4 moves up and down, and the position is accurate when the face paper is pasted. Before the folding knife folds the face paper into the blank box 200, the pressure plate 91 moves up. After the folding knife works, the pressure plate 91 moves down, so that the face paper adheres to the inner wall of the blank box 200, and the pasting effect between the face paper and the blank box 200 is good.

[0033] The two long-side bases 51 or the wide-side bases 61 are provided with a T-shaped pre-pressing plate 58. The pre-pressing plate 58 is located between the folding knife and the folding ear brush 7. The two folding ear brushes 7 are located on both sides of the vertical part of the pre-pressing plate 58. After the first mounting, the face paper can be squeezed by the pre-pressing plate 58 to make the face paper adhere well to the blank box 200. The T-shaped arrangement of the pre-pressing plate 58 and the folding ear brushes 7 located on both sides of the vertical part of the pre-pressing plate 58 will not excessively increase the space occupied by the mounting mechanism. The pre-pressing plate 58 can be installed as needed. The pre-pressing plate 58 is installed on the base through a connecting plate. Considering the installation space, the pre-pressing plate 58 can be set in a T-shape, and the connecting plate is connected to the vertical part of the pre-pressing plate 58.
