Description

Technical Field

[0001] This invention relates to the field of box processing equipment technology, and in particular to an edge gluing and folding device for packaging box processing with anti-spill function. Background Technology

[0002] In the processing of packaging boxes, applying glue to the edges of the box is a necessary step for bonding and folding. The common practice in this field is to use a glue applicator, which usually includes a glue tank tray containing glue and a glue roller partially immersed in the glue. The glue roller rotates and transfers the glue on its surface to the edges of the packaging box it passes over. In order to allow air to be smoothly discharged from the glue-free gaps, effectively reducing the generation of air bubbles, and to ensure that the glue blocks are independent of each other and to prevent the glue from spreading excessively in all directions during pressing, a scraper is set on the side of the glue roller for segmentation.

[0003] The initial distance between the glue tank and the adhesive roller needs to be finely adjusted according to the viscosity of the glue and the process requirements to avoid insufficient glue application on the adhesive roller due to an excessively large gap, or excessive glue being carried out due to an excessively small gap. At the same time, the contact position between the scraper and the adhesive roller also needs to be adjusted accordingly based on the actual situation. In common structures, the movement adjustment of the glue tank and the independent positioning of multiple scrapers are usually performed separately.

[0004] In practical applications, the above structure reveals certain drawbacks. When adjusting after initial installation or changing the type of adhesive, operators need to manually adjust the position of the adhesive tank tray. During this process, adhesive that may drip from the gap between the two will increase the amount of cleaning work if it drips directly onto the conveying equipment or workbench below. Each scraper is usually fixed to the bracket with a separate fastener (such as a screw). When adjusting, it is necessary to loosen the screws one by one, move the scraper to the required position, and then tighten it again. In situations where equipment debugging is required before continuous production, these operations will prolong the preparation time. Summary of the Invention

[0005] The purpose of this invention is to solve the shortcomings of existing technologies, such as the easy dripping of glue during the adjustment of the glue coating mechanism and the cumbersome operation of the scraper adjustment, and to propose an edge glue coating and folding device for packaging box processing with anti-overflow function.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An edge-applying and folding device for packaging box processing with anti-spill function includes a frame including an applicator, a main plate disposed on the frame, and an adhesive roller rotatably disposed on one side of the main plate, and further includes: At least one glue tank tray for holding glue liquid; At least one shelf is slidably disposed on the main tray and used to support the glue tank tray; A movable adjustment mechanism is provided on the main plate and connected to the shelf, and is used to drive the shelf to move the glue tank plate closer to or away from the glue roller; At least one temporary storage box is disposed at the bottom of the main tray and below the gap between the glue pool tray and the adhesive roller, for catching any dripping adhesive.

[0007] In one possible design, the movable adjustment mechanism includes a movable seat slidably disposed at the bottom of the main plate, a rotating cylinder rotatably disposed within the movable seat, and two screws threaded to both ends of the rotating cylinder, wherein rotating the rotating cylinder can drive the movable seat to move. The movable seat is connected to the shelf via a transmission assembly to convert its own movement into the movement of the shelf.

[0008] In one possible design, the transmission assembly includes a guide rod connected to the end of the screw, an inclined guide seat fixed to the end of the guide rod, and a guide frame fixed to the bottom of the main disk and provided with an inclined guide section, wherein the inclined guide seat is slidably sleeved on the inclined guide section; The light rod is equipped with a slip ring, which passes upward through the main plate and is fixedly connected to the shelf.

[0009] In one possible design, a sliding seat is also included, which is slidably disposed on the side of the moving adjustment mechanism, and the sliding seat has a tendency to move toward the moving adjustment mechanism by means of an elastic element; The sliding seat is provided with a snap-fit ​​bracket. When the temporary storage box is in the working position, the snap-fit ​​bracket is located below the protruding edge of the outer wall of the temporary storage box. The device further includes at least one scraper assembly, which includes a blade arm that is oscillatingly disposed at the bottom of the main plate. The sliding seat is provided with an abutment frame. When the sliding seat moves to its final position, the abutment frame pushes the blade arm to oscillate, so that the blade head at the bottom end of the blade arm contacts the surface of the adhesive roller.

[0010] In one possible design, a collar fixedly disposed at the end of the cutter arm is fitted onto a support rod fixed to the bottom of the main disc. The support rod has a protrusion, and the inner wall of the collar has a movable groove that mates with the protrusion to limit the swing angle of the cutter arm.

[0011] In one possible design, the temporary storage box is fitted onto a positioning rod vertically fixed to the bottom of the main disk via a protruding edge on its outer wall, so as to be detachably suspended from the bottom of the main disk.

[0012] In one possible design, the side wall of the glue tank is provided with a limiting seat, and a limiting frame is fixed on the main plate. When the glue tank moves to a working position close to the adhesive roller, a limiting boss provided on one side of the limiting frame is located above the limiting seat.

[0013] In one possible design, the main plate is slidably mounted on the frame via a lifting seat fixed to the side wall, and is driven to lift by a drive component; It also includes a floating seat, which is slidably disposed on the sliding seat by means of an elastic element and has a tendency to move toward the rotating drum.

[0014] In one possible design, it also includes conveyor I, adsorption and transfer mechanism, folding mechanism and conveyor II arranged sequentially along the processing flow direction; The frame of the adhesive applicator is mounted on the body frame of conveyor I, and both ends of the adhesive roller are rotatably connected to two lifting seats through bearing seats.

[0015] In one possible design, the folding mechanism includes two opposing frame seats I and two opposing frame seats II. A cylinder I is fixedly installed on the upper side wall of the frame seat I. A movable frame I is fixedly installed at the piston rod end of the cylinder I, and a rotating roller I is rotatably installed inside the movable frame I. Cylinders II are fixedly installed on both sides below the side wall of the frame seat I. A folding plate is fixedly installed at the piston rod end of the cylinder II. A cylinder III is fixedly installed on the side wall of the frame seat II. A movable frame II is fixedly installed at the piston rod end of the cylinder III, and a rotating roller II is rotatably installed inside the movable frame II. A cylinder IV is located at the center of the four supports, and a placement platform is fixedly mounted on the end of the piston rod of the cylinder IV.

[0016] In this application, during actual use, the main plate is raised to its highest position, and the two glue tanks are first installed in the two slots. Then, the operator manually rotates the drum to drive the screws at both ends to move laterally along the axis. The inclined guide seat at the end of the screw will abut against the inclined guide section, thereby driving the moving seat to move along the slide rail frame towards the side of the adhesive roller. At the same time, the slip ring sleeved on the outer wall of the smooth rod will be displaced axially and move along the sliding hole towards the side of the adhesive roller. The slip ring drives the glue tank to move through the shelf, thereby bringing the glue tank to contact the adhesive roller. At the same time, the limiting seat will move under the limiting boss to automatically lock the glue tank. Then, glue is injected into the glue tank and the adhesive roller is started to rotate. When the adhesive roller rotates, its surface will come into contact with the glue. At this time, the distance between the glue tank and the adhesive roller is adjusted until it is ensured that there is no glue leakage between them. During adjustment, any excess glue will flow into the interior of the temporary storage box. After adjustment, the operator can pull the sliding seat to move it outward along the guide rod. The sliding seat will move the snap-fit ​​bracket, disengaging it from under the protruding edge and releasing the temporary storage box from its limiting position. Then, the temporary storage box can be pulled down and removed from the positioning rod. After that, the sliding seat is released, allowing it to reset via the tension spring. During reset, the removal of the temporary storage box releases the snap-fit ​​bracket from its reset range of motion, allowing the sliding seat to reset further. This causes the floating seat to move and press against the rotating drum, reducing the possibility of the drum rotating unexpectedly through friction. During initial installation, the cutter arm can be moved and adjusted along the frame rod to adjust the position of the cutter head and the adhesive roller. When the temporary storage box is removed and the sliding seat is reset, the sliding seat will drive the abutment frame to move, causing it to push the cutter arm to rotate along the frame rod, so that the end of the cutter head abuts the adhesive roller. At this time, the inner wall end of the movable groove will abut the protrusion to fix it. As the main surface of the packaging box passes below the gluing mechanism, the surfaces of its two folded edges (II) will come into contact with the glued areas on both sides of the adhesive roller, achieving a uniform gluing effect. Afterward, the main surface of the packaging box is conveyed by conveyor I to one side of the folding mechanism. Then, a suction transfer mechanism moves the main surface of the packaging box onto the placement table by suction. The placement table and the shaping frame are then moved downwards synchronously. At this point, cylinder I drives roller I to move below folding edge I, so that folding edge I will contact roller I as it descends, thus lifting it up against the side wall of the shaping frame. The two sides are then joined together. Subsequently, the control cylinder II moves, causing it to drive the folding plate to push the upright secondary edge to fold horizontally, fitting it against the side wall adjacent to the shaping frame. As the main surface of the packaging box continues to move downward, the control cylinder III drives the rotating roller II to move, so that the folding edge II contacts the rotating roller II as it descends, thus standing it up. During the standing up of the folding edge II, the control folding plate moves outward synchronously, moving out of the movement range of the folding edge II, so that the adhesive on the surface of the folding edge II fits and bonds with the secondary edge. After completion, the folding mechanism resets, and the packaging box is then moved onto the conveyor II by the adsorption transfer mechanism.

[0017] In this invention, the edge coating and folding device for packaging box processing with anti-overflow function has a temporary storage box set at the bottom of the main tray, below the gap between the glue pool tray and the glue roller. This can catch glue that may drip from the gap during the adjustment of the glue pool tray position or the operation of the equipment, preventing the glue from dripping directly onto the conveying equipment or workbench below, and reducing the amount of subsequent cleaning work. In this invention, the edge coating and folding device for packaging box processing with anti-overflow function has a scraper assembly that is state-linked with the moving adjustment mechanism through a sliding seat. When the temporary storage box is removed, the sliding seat moves further under the action of the elastic element, which can automatically push the scraper to contact the surface of the adhesive roller, reducing the operation of adjusting and fixing each scraper individually, and facilitating the shortening of preparation time in equipment debugging before continuous production. In this invention, during use, the movable adjustment mechanism is linked with the shelf and glue tank, allowing the operator to simultaneously and synchronously adjust the position of the glue tank relative to the adhesive roller with a single operation (such as rotating the drum). This eliminates the need to adjust multiple components separately and independently in traditional structures, making it easier to quickly set the initial gap when changing the adhesive or debugging. The adjustment mechanism is located at the bottom, which can avoid accidental contact and is simple to operate, ensuring normal operation. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] In one embodiment: Reference Figure 1 A gluing and folding device, which includes, in sequence along the processing flow direction of the main surface 14 of the packaging box, a conveyor I1, a gluing mechanism 5, an adsorption and transfer mechanism 2, a folding mechanism 3 and a conveyor II4.

[0022] refer to Figure 11Conveyor I1 and conveyor II4 are used to transport the main surface 14 of the packaging box. They can be belt conveyors. The adsorption and transfer mechanism 2 is used to transfer the main surface 14 of the packaging box between the conveyor and the folding mechanism 3. It includes a moving platform 211 that can be moved laterally by a horizontal linear module and moved vertically by a vertical linear module. The linear module can be driven by a cylinder. Multiple vacuum adsorption heads 212 are fixed at the bottom of the moving platform 211 for adsorbing the central area of ​​the main surface 14 of the packaging box. A rectangular shaping frame 213 is also fixed at the bottom of the moving platform 211 around the adsorption heads 212. Its size is adapted to the size of the main surface 14 of the packaging box, which serves as the bottom surface.

[0023] refer to Figure 2-4 The glue application mechanism 5 is fixedly installed above the frame of the conveyor I1. The glue application mechanism 5 includes a frame 511 fixedly connected to the frame of the conveyor I1. The frame 511 is equipped with a main plate 6 and an adhesive roller 7 located on one side of the main plate 6. The adhesive roller 7 is driven by a motor to rotate around its axis. The main plate 6 is generally rectangular. Both sides of its top are equipped with shelves 9 (along the conveying direction of the conveyor I1) via linear guide rails. The top of the shelves 9 is machined with a rectangular groove 911. The glue tank 8 can be embedded and placed in the groove 911. The glue tank 8 is a long strip groove used to hold glue. The main plate 6 can be equipped with a separate transparent observation part.

[0024] refer to Figure 6-8 The bottom of the main plate 6 is fixed with two parallel slide rail frames 1011 extending perpendicular to the axis of the adhesive roller 7. The two slide rail frames 1011 are slidably connected by the same movable seat 10. The movable seat 10 has grooves on both sides that match the cross-sectional shape of the slide rail frame 1011. A rotating drum 1012 is rotatably installed inside the movable seat 10. The outer surface of the rotating drum 1012 can be machined with anti-slip texture. The screw 1013 is set along the width direction of the conveyor and can move around its own axis but cannot rotate along the axis. The two ends of the rotating drum 1012 are machined with threads of opposite directions and are threaded onto the screw 1013 on both sides. When the rotating drum 1012 is manually rotated, the rotating drum 1012 will move along the axial direction of the screw 1013 because the screw 1013 is limited by the axis, thereby driving the entire movable seat 10 to slide along the slide rail frame 1011.

[0025] Specifically, a guide rod 1016 is fixedly connected to the end of the screw 1013 away from the rotating drum 1012. The end of the guide rod 1016 slides through the slide rail frame 1011 on the same side and extends to the bottom of the shelf 9 on the same side. Guide frames 1017 are also fixedly installed on both sides of the bottom of the main plate 6. The middle part of the guide frame 1017 is processed into an inclined guide section 1018. The extension direction of the inclined guide section 1018 is at an angle to the conveyor conveying direction. An inclined guide seat 1019 is slidably sleeved on the outer wall of the inclined guide section 1018. The inclined guide seat 1019 is fixedly connected to the end of the guide rod 1016 on the same side by screws. Long strip-shaped sliding holes 1015 are also opened on both sides of the bottom of the main plate 6. A slip ring 1014 is sleeved on the outer wall of the guide rod 1016. The slip ring 1014 passes upward through the sliding hole 1015 and is fixedly connected to the shelf 9 above by screws.

[0026] In this embodiment, by setting the inclined guide section 1018, the rotating drum 1012 drives the screw 1013 to move axially. The inclined guide seat 1019 at the end of the smooth rod 1016 will slide along the inclined guide section 1018 through the guiding effect of the inclined surface. This process will simultaneously generate a vertical component motion, thereby driving the shelf 9 and the glue tank 8 to move closer to or away from the adhesive roller 7 through the slip ring 1014.

[0027] The glue application mechanism 5 also includes two temporary storage boxes 12, which are located on both sides of the bottom of the main plate 6. Each temporary storage box 12 is located below the gap between the edge of the main plate 6 and the glue roller 7 on the same side. Multiple positioning rods 1201 are fixed vertically downward at the bottom of the main plate 6, for example, two rods are set on each side. A raised edge 1202 is provided on the upper part of the outer wall of the temporary storage box 12. Through holes corresponding to the positions of the positioning rods 1201 are opened on the raised edge 1202, so that the temporary storage box 12 can be sleeved on the positioning rods 1201 through the raised edge 1202 to achieve suspension positioning.

[0028] refer to Figure 9-10 A sliding seat 11 is provided on the side of the movable seat 10 (e.g., the side closer to the operator). Both sides of the sliding seat 11 are provided with elastic elements (guide rods 1101 fixed to the sliding seat 11, slide rails 1011 on the same side are slidably sleeved on the guide rods 1101, tension springs 1102 are sleeved on the guide rods 1101, one end of the tension springs 1102 is hooked on the slide rails 1011, and the other end is hooked on the sliding seat 11). In the natural state, the tension springs 1102 have the tendency to pull the sliding seat 11 towards the movable seat 10. Both sides of the sliding seat 11 are also fixed with brackets 1103. When the temporary storage box 12 is suspended on the positioning rod 1201, the end of the bracket 1103 is located at the bottom of the protruding edge 1202 and abuts against the outer wall of the temporary storage box 12, thereby preventing the temporary storage box 12 from falling out.

[0029] The adhesive applicator 5 also includes multiple blade arms 1304 for scraping adhesive film. The bottom end of the blade arm 1304 is fixed with a blade head 1305 by screws. The blade head 1305 can be made of polyurethane or rubber. The top end of the blade arm 1304 is fixed with a collar 1302. On both sides of the bottom of the main plate 6 and on the side of the temporary storage box 12 away from the adhesive roller 7, there are support rods 13. Multiple collars 1302 are respectively fitted on two support rods 13. The outer wall of the support rod 13 is machined with an integrally formed protrusion 1301. The cross section of the protrusion 1301 can be fan-shaped or semi-circular. The inner wall of the collar 1302 is provided with an arc-shaped movable groove 1303. When the collar 1302 is fitted on the support rod 13, the protrusion 1301 is located in the movable groove 1303, so that the blade arm 1304 can swing around the axis of the support rod 13 within a certain angle range. At the same time, the arc length of the movable groove 1303 limits the maximum angle of swing.

[0030] The sliding seat 11 is also fixed with abutment brackets 1307 on both sides. When the sliding seat 11 moves to the limit position in the direction of the moving seat 10 under the action of the tension spring 1102, the end of the abutment bracket 1307 will contact the side of the multiple blade arms 1304 on the same side. The protrusion 1301 is provided with a rough surface 1306 on the side wall facing the swing direction of the blade arm 1304, for example, formed by sandblasting, to increase the friction.

[0031] The working process of the device is as follows: In the initial state, the main plate 6 is in a high position, and the two glue pool trays 8 are placed in the grooves 911 of the shelf 9 but are not in contact with the adhesive roller 7. The operator manually rotates the rotating drum 1012. The rotating drum 1012 rotates and moves along the screw 1013. When the screw 1013 is in motion, the guide seat 1019 is driven to slide along the guide section 1018 through the guide rod 1016, which forces a horizontal displacement toward the adhesive roller 7. The slip ring 1014 drives the shelf 9 and the glue pool trays 8 to move toward the adhesive roller 7 through the sliding hole 1015 until the side wall of the glue pool tray 8 makes slight contact with the surface of the adhesive roller 7.

[0032] After adjustment, inject glue into the glue tank 8 and start the glue roller 7 to rotate. At this time, the rotating drum 1012 can be finely adjusted again to control the gap between the glue tank 8 and the glue roller 7 to obtain a suitable amount of glue. During this adjustment process, if any glue drips from the gap, it will fall into the temporary storage box 12 below. After the adjustment is completed, the operator pulls the sliding seat 11 outward to overcome the tension of the tension spring 1102, so that the snap-fit ​​bracket 1103 is disengaged from below the protruding edge 1202 of the temporary storage box 12. At this time, the temporary storage box 12 can be removed downward.

[0033] Release the sliding seat 11, and the sliding seat 11 will reset under the action of the tension spring 1102. During the reset, due to the removal of the temporary storage box 12, the locking bracket 1103 is released from the reset range restriction, and the sliding seat 11 can be reset further on the original basis, so that the abutment bracket 1307 can contact and push the knife arm 1304 to swing around the frame rod 13, so that the cutting edge of the knife head 1305 abuts against the surface of the rotating adhesive roller 7, dividing the adhesive film on the surface of the adhesive roller 7 into several independent strip areas. When the knife arm 1304 swings to the working position, the end of the movable groove 1303 of the collar 1302 will tightly abut against the protrusion 1301 of the frame rod 13. The rough surface 1306 helps to prevent the knife arm 1304 from axially loosening under equipment vibration.

[0034] When the main surface 14 of the packaging box is conveyed by the conveyor I1 and passes under the glue coating mechanism 5, the folded edge II1403 areas on both sides to be coated with glue will come into contact with the parts on both sides of the glue roller 7 where glue strips have been scraped off, and the glue is evenly coated. Then the coated main surface 14 of the packaging box is conveyed to the folding station and transferred by the adsorption transfer mechanism 2 to the folding mechanism 3 for folding and bonding.

[0035] Optionally, the sliding connection between the smooth rod 1016 and the slip ring 1014 can also be achieved using a linear bearing to reduce friction.

[0036] refer to Figure 11 The main surface 14 of the packaging box is located on the top of the placement platform 322 and the bottom of the shaping frame 213. The main surface 14 of the packaging box is provided with folded edge I 1401 on both opposite sides, and secondary edge 1402 is provided on both sides of folded edge I 1401. The main surface 14 of the packaging box is also provided with folded edge II 1403 on the other opposite sides.

[0037] The folding mechanism 3 includes two opposing frame bases I 311 and two opposing frame bases II 317. A cylinder I 312 is fixedly installed on the upper side wall of the frame base I 311. The piston rod end of the cylinder I 312 is fixed to a movable frame I 313 by bolts. A rotating roller I 314 is rotatably installed inside the movable frame I 313 via bearings. Cylinders II 315 are fixedly installed on both sides below the side wall of the frame base I 311. A folding plate 316 is fixed to the end of the piston rod of the cylinder II 315 by bolts. A cylinder III 318 is fixedly installed on the side wall of the frame base II 317. A movable frame II 319 is fixed to the end of the piston rod of the cylinder III 318 by bolts. A rotating roller II 320 is rotatably installed inside the movable frame II 319 via bearings. A base is set at the center of the four frame bases. A vertical cylinder IV 321 is installed inside the base. A placement platform 322 is fixed to the end of the piston rod of the cylinder IV 321 by bolts.

[0038] Specifically, the adsorption and transfer mechanism 2 moves the main surface 14 of the packaging box onto the placement platform 322 via adsorption. Then, the placement platform 322 and the shaping frame 213 are moved downwards synchronously. At this point, cylinder I 312 drives roller I 314 to move below the folding edge I 1401, so that the folding edge I 1401 will contact roller I 314 as it descends, thus standing upright and fitting against the side wall of the shaping frame 213. Then, cylinder II 315 moves, causing the folding plate 316 to push the upright secondary edge 1402 horizontally, folding it in conjunction with... The adjacent side walls of the shaping frame 213 are attached together. Then, as the main surface 14 of the packaging box continues to move downward, the control cylinder Ⅲ318 drives the rotating roller Ⅱ320 to move, so that the folded edge Ⅱ1403 contacts the rotating roller Ⅱ320 when it descends, thus standing up. During the process of standing up the folded edge Ⅱ1403, the control plate 316 moves outward synchronously, leaving the moving range of the folded edge Ⅱ1403, so that the glue on the surface of the folded edge Ⅱ1403 is attached to the secondary edge 1402 for bonding. After the end, the folding mechanism 3 is reset, and the packaging box is moved to the conveyor Ⅱ4 by the adsorption transfer mechanism 2.

[0039] This application can be used in the field of carton processing equipment, or in other fields applicable to this application.

[0040] In another embodiment: Reference Figure 2 An edge gluing and folding device for packaging box processing with anti-overflow function is applied to the field of box processing equipment. The structure of this embodiment is basically the same as that of the previous embodiment. The difference is that, based on the above embodiment one, the lifting and adjusting function of the gluing mechanism 5 and the auxiliary limiting structure of the glue pool tray 8 are further defined.

[0041] Two lifting seats 513 are slidably installed on the inner walls of both sides of the frame 511 via vertical guide rails. The left and right sides of the main plate 6 are fixedly connected to these two lifting seats 513 respectively. A driving component (cylinder V 512) is fixedly installed on the side wall of the frame 511. The piston rod end of cylinder V 512 is fixed to the lifting seat 513 on the same side. By controlling the synchronous action of the two cylinders V 512, the main plate 6 and all its components can be driven to lift as a whole. The two ends of the adhesive roller 7 are rotatably connected to the lifting seats 513 on both sides via bearing seats. One end of the roller is connected to the motor output shaft fixed on the lifting seat 513 via a coupling.

[0042] refer to Figure 4-5Limit seats 811 are welded to the upper part of both sides of the glue tank 8. When the glue tank 8 is placed into the groove 911 of the shelf 9, the limit seats 811 rest on the top of the frame of the shelf 9. Multiple limit frames 812 are also fixed on the top of the main plate 6. The top of the limit frame 812 bends towards the glue tank 8 to form a limit boss 813. When the operating drum 1012 drives the glue tank 8 to move towards the adhesive roller 7 and reach the working position, the limit seats 811 on the glue tank 8 will move to the bottom of the limit boss 813. At this time, the limit boss 813 presses the limit seat 811 from above, and together with the shelf 9 below, forms a vertical limit on the glue tank 8 to prevent it from jumping or tilting under the vibration of the equipment or the rotation of the adhesive roller 7.

[0043] refer to Figure 6-7 A floating seat 15 is slidably connected to the side of the sliding seat 11 facing the rotating drum 1012 via a transverse guide rod and guide sleeve. An elastic element (compression spring, which makes the floating seat 15 tend to move towards the rotating drum 1012) is provided between the floating seat 15 and the sliding seat 11. When the sliding seat 11 is fully reset under the action of the tension spring 1102 (that is, the temporary storage box 12 has been removed), the floating seat 15 is pressed tightly against the outer surface of the rotating drum 1012 under the action of the spring force. The friction between the floating seat 15 and the surface of the rotating drum 1012 (which can be set to a rough surface) can form a damping mechanism, which to a certain extent prevents the rotating drum 1012 from rotating due to accidental contact or equipment vibration, thereby increasing stability. The sliding seat 11 can also be fixed separately by means of countersunk bolts, snap-fit ​​mechanisms, etc.

[0044] This device also includes a PLC controller, which is electrically connected to the motor driving the adhesive roller 7, cylinders I 312, II 315, III 318, IV 321, V 512, the linear module drive of the adsorption and transfer mechanism 2, and the control valve of the vacuum adsorption head 212. The PLC controller has a pre-stored control program to control each actuator to complete the conveying, gluing, transfer, folding and unloading processes of the packaging box according to the preset timing.

[0045] The other parts of this embodiment are the same as those in Embodiment 1, and will not be repeated here.

[0046] However, as is well known to those skilled in the art, the working principles and wiring methods of the conveyor, cylinder and adsorption transfer mechanism 2 are all conventional means or common knowledge, and will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0047] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0048] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
