[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] Implementation examples, by Figures 1 to 10The present invention includes a gluing table 1; a multi-axis actuator 2 is mounted on the gluing table 1, and an extrusion nozzle 3 is installed on the multi-axis actuator 2. The output end of the extrusion nozzle 3 is used to apply glue to the joint of two panels; the gluing table 1 is also equipped with a directional clamping device, which is used to fix the panels required for packaging box forming; U-shaped fixed columns 4 with opposite openings are respectively installed on both sides of the top of the gluing table 1, and a supporting horizontal plate 5 is installed at the bottom of the U-shaped fixed column 4. A drive motor 6 is installed on the opposite back of the two supporting horizontal plates 5, and a reciprocating scratch removal mechanism is provided on the drive motor 6 to remove glue marks caused by overflowing glue during packaging box forming; a drive shaft 7 is installed on the top of the supporting horizontal plate 5, and an exhaust cooling assembly is also provided on the drive shaft 7 to accelerate the glue solidification and forming speed; the drive shaft 7 is also equipped with... The device includes a drive bevel gear 8; the reciprocating scratch removal mechanism includes a drive gear 9 mounted on the output end of the drive motor 6, and a drive column 10 mounted on the edge of the drive gear 9 away from the supporting horizontal plate 5; a displacement block 11 is also mounted on the side of the drive gear 9, and a through rectangular groove 12 is provided on the side of the displacement block 11 near the drive gear 9, the rectangular groove 12 slidingly engaging with the drive column 10; displacement guide plates 13 are also mounted on both sides of the displacement block 11, and guide grooves 14 are provided at the top and bottom of the displacement guide plates 13; guide pulleys 15 are slidably connected to the guide grooves 14, and guide bases 16 are mounted on the guide pulleys 15, the guide bases 16 being mounted on the supporting horizontal plate 5; guide telescopic rods 17 are mounted on the opposite ends of the two displacement guide plates 13, and the two guide telescopic rods 17 are connected to a scraping block 18, the scraping block 18 fitting against the intersection of the two panels. The operator places one of the panels required for packaging box forming horizontally on the top of the gluing table 1, and the other vertically above the edge of the horizontally placed panel. Glue is applied to the edge of the horizontally placed panel by operating the extrusion nozzle 3. The multi-axis actuator 2 allows the extrusion nozzle 3 to be operated at different positions for gluing, reducing limitations during gluing. The vertical panel is fixed at its current height by a directional clamping device. Using the telescopic U-post 25, the clamped panel is moved downwards, causing the bottom of the vertical panel to contact the top edge of the horizontal panel, pressing the vertical panel down onto the horizontal panel and bonding the two sides together. Repeating these steps fixes multiple sides of the packaging box, completing the forming process. The packaging box is formed by splicing multiple sides. However, if too much glue is applied when two panels are pressed together, excess glue will overflow due to pressure, resulting in unsightly glue marks on the packaging box surface. In this case, the drive motor 6 is activated to... The output end drives the drive gear plate 9 to rotate, causing the drive column 10 to slide back and forth within the rectangular slide groove 12. This causes the displacement block 11 on it to slide back and forth at the guide pulley 15 via the guide slide groove 14 on the displacement guide plate 13, which limits the movement of the displacement block 11. Under the action of the guide telescopic rod 17, the scraping block 18 is driven to move back and forth. The scraping block 18 is moved to the intersection of the vertical panel and the horizontal panel along with the directional clamping device, so that the working sharp part of the scraping block 18 contacts the glue residue caused by the overflowing glue. The reciprocating movement of block 18 cleans up the aforementioned adhesive residue, scraping it off to prevent further adhesion to the panel. This cleans up adhesive residue caused by pressure overflow, preventing it from forming on the edges and surface of the packaging box and causing unsightly defects during molding. The device effectively cleans adhesive residue generated during packaging box molding, avoiding any impact on the appearance quality of the finished packaging box. This improves the device's efficiency and quality in packaging box production and reduces limitations in its use.

[0018] The directional clamping device in this embodiment includes a T-shaped base 19 fixedly installed at the bottom of the coating table 1. Rotary motors 20 are installed on opposite sides of the T-shaped base 19. A displacement screw 21 is connected to the output end of each rotary motor 20. A positioning base 22 is installed at the end of the displacement screw 21 away from the rotary motor 20, and the positioning base 22 is fixedly installed on the coating table 1. A positioning block 23 is threaded onto the displacement screw 21, and a positioning slide post 24 is fixedly installed on the positioning block 23. The positioning slide post 24 passes through the positioning base 22 and the two slide in a sliding engagement. The positioning slide posts 24 on both sides of the bottom of the coating table 1 are respectively connected to telescopic U-posts 25. The opposite face of 5 is connected to the opposite back face of the two U-shaped fixed columns 4; a positioning horizontal plate 26 is installed at the opposite end of the two U-shaped fixed columns 4, and two symmetrically arranged limiting cylinders 27 are connected through the side of the positioning horizontal plate 26 away from the telescopic U column 25, and the limiting cylinders 27 and the positioning horizontal plate 26 are slidably engaged; the ends of the two limiting cylinders 27 away from the telescopic U column 25 are connected to a limiting U seat 28; a limiting wheel 29 is installed in the limiting U seat 28, and the side of the panel is located at the moving path of the limiting wheel 29; a limiting spring 30 is sleeved on the limiting cylinder 27, one end of the limiting spring 30 is fixedly connected to the positioning horizontal plate 26, and the other end is fixedly connected to the limiting U seat 28; By activating the rotary motor 20, its output end drives the displacement screw 21 to rotate on the positioning base 22. This causes the threaded positioning blocks 23 to move relative to the positioning base 22 via the positioning slide 24, thereby moving the two positioning blocks 23 relative to each other. This, in turn, causes the two telescopic U-pillars 25 to move relative to each other. The positioning plate 26 on these U-pillars, under the action of the limiting cylinder 27 and the limiting spring 30, moves the limiting U-seat 28 towards the vertically placed panel. This causes the limiting U-seats 28 on both sides of the top of the glue application table 1 to move relative to each other, allowing the limiting wheels 29 to contact the vertical panel. This clamps and fixes the vertical panel in its current position and angle for bonding different panels, preventing panel wobbling during bonding and avoiding deviations in the fixing position or installation angle between different surfaces. This improves the quality of the packaging box production process. It is worth mentioning that each positioning... The movement of block 23 is controlled by a separate displacement screw 21, allowing the limiting wheels 29 on both sides of the vertical panel to move to different positions to fix the panel at different locations, reducing the limitations of the device during use. Simultaneously, once the limiting wheels 29 are in contact with the panel, the continued movement of the positioning block 23 causes the positioning horizontal plate 26 to move at the upper limit of the limiting cylinder 27, putting the limiting spring 30 in a buffered state. This buffering effect provides some reserve force, enhancing the friction and strength between the limiting wheels 29 and the panel. The aforementioned buffering force also reduces the impact force on the panel during adhesive fixing, further improving the stability of the device during packaging box forming. Furthermore, the rotation of the limiting wheels 29 facilitates the movement of the panel after clamping, making it easier to adjust the position of different surfaces during packaging box forming. It also facilitates disengagement after the surface is adhered, further enhancing the device's effectiveness.

[0019] The exhaust cooling assembly of this embodiment includes a double-sided cam 31 mounted on the end of the drive shaft 7 away from the support plate 5, with two symmetrically arranged protrusions on the double-sided cam 31; pressure blocks 32 are also symmetrically arranged on both sides of the double-sided cam 31, with the opposing surfaces of the two pressure blocks 32 located at the rotation path of the sidewalls of the two protrusions on the double-sided cam 31; a limiting base 33 is mounted on the support plate 5, and a limiting shaft 34 is mounted on the limiting base 33. One end of the 4 is connected to a rotating gear 35, which meshes with the drive gear 9; the other end of the limiting shaft 34 is equipped with a reciprocating bevel gear 36, which meshes with the drive bevel gear 8; a set of pressing cylinders 37 are respectively installed on the opposite sides of the two pressure blocks 32, and each set of pressing cylinders 37 is slidably connected to a pressing base 38, which is fixedly installed on the support plate 5; a pressing spring 39 is sleeved on the pressing cylinder 37. One end of the pressure spring 39 is fixedly connected to the pressure base 38, and the other end is fixedly connected to the pressure block 32; pressure square plates 40 are installed on the opposite ends of the two sets of pressure cylinders 37; a pressure square box 41 is also installed on the top of the support plate 5, and the pressure square plate 40 is located inside the pressure square box 41 and the two are slidably engaged; an air inlet valve is installed on the top of the pressure square box 41; an air outlet valve is connected to the side of the pressure square box 41 away from the pressure square plate 40; the air inlet valve is located at the air outlet valve. Between the valve and the pressure plate 40, the air inlet valve is not located in the moving path of the pressure plate 40; a bent pipe 42 is installed at the air outlet valve, and a connecting transverse air pipe 43 is installed at the output end of the bent pipe 42; a transfer hollow pipe 44 is installed on the scraping block 18, and several air delivery nozzles 45 are installed on the transfer hollow pipe 44, with the output ends of the air delivery nozzles 45 facing the intersecting glued area of ​​the two panels; the transverse air pipe 43 is located inside the transfer hollow pipe 44 and the two are in sliding fit. When the scraper block 18 cleans the excess adhesive generated at the intersection of the vertical and horizontal panels during bonding, the rotating drive gear 9 meshes with the rotating gear 35, causing it to rotate. Under the action of the limiting shaft 34, this drives the repeating bevel gear 36 to rotate, which in turn meshes with the drive bevel gear 8. This, in turn, drives the double-sided cam 31 on the drive shaft 7 to rotate continuously. The cam 31 has two symmetrical protrusions, and there are also two symmetrical pressure blocks 32 on both sides of the double-sided cam 31. This ensures that when the double-sided cam 31 rotates, its two protrusions will... When the cam 31 contacts the two pressure blocks 32, it applies lateral pressure, causing the pressure cylinder 37 to move at the pressure base 38, thus putting the pressure spring 39 in a buffered state. This then drives the pressure plate 40 forward. When the double-sided cam 31 rotates and no longer contacts the pressure blocks 32, it is no longer subjected to lateral pressure, causing the pressure spring 39 to reset. This allows the pressure blocks 32 to reset and move, thus resetting the forward-moving pressure plate 40, placing it within the pressure box 41. The pressure plate 40 moves forward in a reciprocating motion. When the pressure plate 40 moves forward, the inlet valve closes while the outlet valve opens, allowing gas from the pressure box 41 to enter the transverse air pipe 43 through the bend pipe 42. When the pressure plate 40 returns to its original position within the pressure box 41, the outlet valve closes and the inlet valve opens, drawing outside gas into the pressure box 41. This gas is then discharged into the transverse air pipe 43 through the next opening of the outlet valve, ensuring a continuous flow of gas through the transverse air pipe 43 into the transfer hollow pipe 44, where it is further processed through several transmission lines. The air nozzle 45 can discharge the aforementioned gas to the intersection of the vertical and horizontal panels, thereby increasing the curing speed of the adhesive applied at the joint between the two panels and accelerating the cooling speed of the adhesive for rapid curing. This reduces the time required for the device to produce molded packaging boxes and improves the efficiency of the device. At the same time, as the hardness of the adhesive increases after curing, the adhesion between the adhesive residue and the panel surface decreases, making it easier for the adhesive residue caused by overflowing adhesive to be scraped and peeled off by the scraper block 18. This reduces the difficulty of cleaning the adhesive residue and improves the effectiveness of the device. It is worth mentioning that when the scraping block 18 moves back and forth, the transfer hollow tube 44 on it moves to the upper limit of the transverse air tube 43. This does not affect the movement of the scraping block 18, but also allows the gas in the pressure box 41 to continuously enter the transfer hollow tube 44 through the transverse air tube 43 and be applied to the intersection of the two panels by the air delivery nozzle 45, further reducing the limitations of the device during use.
