Description

Technical Field

[0001] This invention relates to the field of packaging equipment, and more particularly to a gluing device for irregularly shaped paper boxes. Background Technology

[0002] A cardboard box is a three-dimensional shape, composed of multiple faces that are moved, stacked, folded, and enclosed to form a polyhedron. The faces in this three-dimensional structure divide space through techniques such as cutting, rotating, and folding; different face shapes can convey different visual emotions. Cardboard box design requires attention to the connection between the display surface, sides, and top and bottom, while also rationally placing packaging information elements. Irregularly shaped cardboard boxes are a type of cardboard box that differs from conventional cardboard box shapes.

[0003] In the automated gluing process of irregularly shaped cardboard boxes, the steps of applying glue, folding, and pressing are usually completed sequentially. Currently, most gluing equipment directly feeds individual cardboard boxes into a pneumatic or roller pressing mechanism for extrusion and bonding via a conveyor belt after the glue application and folding processes. This "single-in, single-out" operation method results in frequent start-ups and shutdowns of the pneumatic mechanism, leading to low production efficiency. Furthermore, each extrusion only acts on a single cardboard box, resulting in low energy utilization. To address this, some equipment has attempted to set up a temporary stacking station before entering the extrusion process to achieve batch extrusion. However, existing stacking methods often rely solely on the inertial pushing of the conveyor belt, lacking active positioning and alignment methods. This results in uneven and severely misaligned stacks of multiple cardboard boxes, which can easily cause box deformation, overlap misalignment, or poor bonding during subsequent extrusion, seriously affecting the yield and appearance consistency of the gluing product. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of low efficiency, stacking misalignment and low yield in the prior art, and to provide a gluing device for irregularly shaped paper boxes.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution: This invention provides a gluing device for irregularly shaped paper boxes. In this technical solution, the irregularly shaped paper boxes are pushed by the pushing mechanism and blocked by the blocking mechanism, so that multiple irregularly shaped paper boxes can be collected before entering the pneumatic mechanism of the pneumatic gluing unit, and then enter the pneumatic gluing unit for extrusion. The extrusion and gluing of multiple irregularly shaped paper boxes can be completed in one go. At the same time, by blocking and pushing, the irregularly shaped cardboard boxes can be positioned so that multiple irregularly shaped cardboard boxes can be completely overlapped, avoiding the deformation and insufficient adhesive force caused by the misalignment of multiple irregularly shaped cardboard boxes during compression, thus improving the gluing quality of irregularly shaped cardboard boxes.

[0006] Preferably, the control component includes a fixed guide post and a one-way threaded shaft, and the top of the main push plate is connected to a plurality of fixed guide posts, the top of which is connected to the bottom of the mounting bracket; The surface of the one-way threaded shaft is rotatably connected to the mounting bracket, and an adjusting plate is threadedly connected to the surface of the one-way threaded shaft. Connecting support bars are provided on both sides of the adjusting plate. Both ends of the connecting support bar are rotatably connected to rotating connecting seats. The upper rotating connecting seat is connected to the side of the adjusting plate, and the lower rotating connecting seat is connected to the top of the side push plate.

[0007] In this technical solution, the position of the two side push plates is adjusted by the control component to expand the area of ​​the pushing mechanism.

[0008] Preferably, the side push plate is slidably connected to the main push plate via a sliding limiting assembly. The sliding limiting assembly includes sliding connecting columns. Multiple sliding connecting columns are connected to the side of the side push plate near the main push plate. The surface of the sliding connecting columns is slidably connected through the side of the main push plate. The end of the sliding connecting column away from the side push plate is connected to one side of the anti-detachment plate, and the anti-detachment plate is slidably disposed in the inner cavity of the main push plate.

[0009] In this technical solution, the movement trajectory of the side push plate is limited by a sliding limit component.

[0010] Preferably, a positioning component is slidably disposed between the mounting bracket and the fixed bracket. The positioning component includes an anti-deviation shaft. Multiple anti-deviation shafts are connected to the side of the mounting bracket near the fixed bracket. The surface of the anti-deviation shaft is slidably connected through the fixed bracket. The end of the anti-deviation shaft furthest from the mounting bracket is connected to the positioning connecting plate.

[0011] In this technical solution, the movement trajectory of the mounting bracket is limited by a positioning component.

[0012] Preferably, the blocking assembly includes a lifting device, and a blocking plate is connected to the bottom output end of the lifting device; The top of the lifting device is mounted on the bottom of the mounting plate.

[0013] In this technical solution, a blocking component is used to block irregularly shaped cardboard boxes.

[0014] Preferably, the synchronization control component includes a fixed side plate and a bidirectional threaded shaft, and the top of the pneumatic paste box unit is connected to two symmetrically distributed fixed side plates, and the bidirectional threaded shaft is rotatably connected to the two fixed side plates; One end of the bidirectional threaded shaft is connected to a rotational power source, and two symmetrically distributed movable plates are threadedly connected to the surface of the bidirectional threaded shaft. Each of the two movable plates is connected to a mounting strip on one side.

[0015] In this technical solution, the distance between the two blocking components is adjusted by a synchronous control component to accommodate irregularly shaped paper boxes of different widths.

[0016] Preferably, a plurality of limiting posts are connected between the two fixed side plates, and the surfaces of the limiting posts are slidably connected through the movable plate.

[0017] In this technical solution, the movement trajectory of the moving plate is limited by a limiting post.

[0018] Preferably, the positioning push unit further includes a limiting guide mechanism, the limiting guide mechanism includes a mounting shaft, both ends of the mounting shaft are connected to a support frame, and the bottom of the support frame is connected to the pneumatic glue box unit; The mounting shaft surface is equipped with two symmetrically distributed side-pushing components and two symmetrically distributed guide components.

[0019] In this technical solution, a limiting and guiding mechanism is used to guide the irregularly shaped paper box, which facilitates the positioning of the irregularly shaped paper box and its entry into the pneumatic gluing unit for extrusion.

[0020] Preferably, the side push assembly includes a sliding block, which is slidably mounted on the surface of the mounting shaft and slidably connected to the surface of the mounting column. A locking bolt is threadedly connected to one side of the sliding block, and one end of the locking bolt abuts against the surface of the mounting column. The end of the mounting post furthest from the sliding block is connected to a finite side plate.

[0021] In this technical solution, the positions of the two sides of the irregularly shaped cardboard box are defined by the side push components on both sides.

[0022] Preferably, the guide assembly includes a mounting block, which is slidably mounted on the surface of the mounting shaft and slidably connected to the surface of the adjusting column. A fastening bolt is threadedly connected to one side of the mounting block, and one end of the fastening bolt abuts against the surface of the adjusting column. A roller is installed at the end of the adjusting column away from the mounting block.

[0023] In this technical solution, the irregularly shaped paper box is guided by a guide component to facilitate its movement.

[0024] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of the present invention.

[0025] The positive and progressive effects of this invention are as follows: This invention, through the coordinated operation of the pushing mechanism and the blocking mechanism in the positioning and pushing unit, can automatically collect and stack multiple paper boxes that have been coated and folded at the junction of the conveying and folding unit and the pneumatic gluing unit before the irregularly shaped paper boxes enter the pneumatic gluing unit for pneumatic extrusion. Then, they are uniformly sent into the pneumatic gluing unit for pneumatic extrusion, so that multiple irregularly shaped paper boxes can be glued simultaneously in a single pneumatic action. This significantly reduces the start-stop frequency of the pneumatic components and the processing time of a single piece, effectively improving the overall production cycle and capacity, increasing production efficiency, and achieving batch stable pressure gluing.

[0026] The front end of the irregularly shaped cardboard box is blocked and positioned by the material blocking mechanism, and the material pushing mechanism pushes it from the rear end. The two work together to ensure that multiple irregularly shaped cardboard boxes can completely overlap and stack neatly before entering the pneumatic gluing unit. This effectively avoids problems such as box deformation, overlap misalignment or uneven gluing force caused by misalignment of the cardboard boxes during subsequent pneumatic compression, and improves the gluing firmness and appearance consistency of the irregularly shaped cardboard boxes.

[0027] By adjusting the components, the side push plates on both sides move synchronously closer to or further away from the main push plate, thereby achieving rapid and stepless adjustment of the push surface width. This can accommodate large cardboard boxes to provide sufficient support and prevent tilting during push, and can also narrow the push surface when processing small cardboard boxes to reduce movement resistance and energy consumption, thus enhancing the equipment's versatility and energy efficiency.

[0028] The synchronous control component allows two symmetrically arranged blocking components to move towards or away from each other, thereby precisely adjusting the distance between the two blocking blocks to accommodate irregularly shaped cartons of different widths, ensuring the reliability and adaptability of the blocking action, and preventing cartons from shifting or jamming.

[0042] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0043] Figures 1 to 12 The diagram shown is a structural schematic of an embodiment of the gluing device for irregularly shaped paper boxes of the present invention.

[0044] A gluing device for irregularly shaped paper boxes includes a gluing unit 1, a conveying and folding unit 2, and a pneumatic gluing unit 3. The gluing unit 1, the conveying and folding unit 2, and the pneumatic gluing unit 3 are connected in sequence. A positioning and pushing unit is provided between the conveying and folding unit 2 and the pneumatic gluing unit 3. The glue application unit 1 mainly includes a glue storage container, glue supply pipeline and glue application actuator, such as a glue spray head or a roller. When the irregularly shaped cardboard box passes by with the conveyor belt, the glue application actuator accurately applies glue to the joint position that needs to be glued according to the preset folding trajectory of the cardboard box, completing the glue preparation before gluing the box.

[0045] The conveying and folding unit 2 mainly includes a conveyor belt and folding guide components such as folding rods, guide plates or paddles set along the path. It receives the irregularly shaped cardboard box after it has been glued by the gluing unit 1 and conveys it forward. During the movement, the irregularly shaped cardboard box passes the guide components, and its two side folds are folded inward to cover the glued position. At this time, the irregularly shaped cardboard box is in a preliminary closed state. Then it is sent to the end of the unit to wait for the next extrusion process.

[0046] The pneumatic gluing unit 3 includes a material conveyor belt, an external frame, and pneumatic components. The external frame supports the material conveyor belt and pneumatic components. The material conveyor belt moves and transports the irregularly shaped paper boxes, and the pneumatic components squeeze the irregularly shaped paper boxes to achieve the gluing operation.

[0047] The irregularly shaped paper box is coated with glue by the glue application unit 1, and then conveyed and folded by the conveying and folding unit 2. During the conveying process, the irregularly shaped paper box is folded to cover the glued area. Then, the pneumatic gluing unit 3 uses air pressure to squeeze the irregularly shaped paper box, so that the glue is fully adhered to the irregularly shaped paper box, thus realizing the gluing process of the irregularly shaped paper box.

[0048] The positioning and pushing unit includes a pushing mechanism and a blocking mechanism. The pushing mechanism is installed at one end of the conveying and folding unit 2 near the pneumatic gluing unit 3, and the blocking mechanism is installed at one end of the pneumatic gluing unit 3 near the conveying and folding unit 2. The pushing mechanism includes a fixed bracket 4, which is connected to the conveying folding unit 2. A push-pull device 5 is connected to one side of the fixed bracket 4. The execution end of the push-pull device 5 is connected to a mounting frame 6. A main push plate 7 is provided below the mounting frame 6. Side push plates 8 are provided on both sides of the main push plate 7. The mounting frame 6, the main push plate 7 and the side push plates 8 are movably connected by an adjustment component 9. The material blocking mechanism includes two blocking components 10, both of which are connected to the execution end of the synchronization control component 11, which is installed at the pneumatic gluing unit 3.

[0049] In this technical solution, the irregular paper boxes are pushed by the pushing mechanism and blocked by the blocking mechanism, so that multiple irregular paper boxes can be collected before entering the pneumatic mechanism of the pneumatic gluing unit 3, and then enter the pneumatic gluing unit 3 for extrusion. The extrusion and gluing of multiple irregular paper boxes can be completed in one go. At the same time, by blocking and pushing, the irregularly shaped cardboard boxes can be positioned so that multiple irregularly shaped cardboard boxes can be completely overlapped, avoiding the deformation and insufficient adhesive force caused by the misalignment of multiple irregularly shaped cardboard boxes during compression, thus improving the gluing quality of irregularly shaped cardboard boxes.

[0050] The control component 9 includes a fixed guide post 91 and a one-way threaded shaft 92. The top of the main push plate 7 is connected to a plurality of fixed guide posts 91, and the top of the fixed guide post 91 is connected to the bottom of the mounting bracket 6. The surface of the one-way threaded shaft 92 is rotatably connected to the mounting bracket 6, and an adjusting plate 93 is threadedly connected to the surface of the one-way threaded shaft 92. Connecting support bars 94 are provided on both sides of the adjusting plate 93. Both ends of the connecting support bar 94 are rotatably connected to rotating connecting seats 95. The upper rotating connecting seat 95 is connected to the side of the adjusting plate 93, and the lower rotating connecting seat 95 is connected to the top of the side push plate 8.

[0051] In this technical solution, the position of the two side push plates 8 is adjusted by the control component 9 to expand the area of ​​the pushing mechanism.

[0052] The adjusting plate 93 has a sliding hole, and the fixed guide post 91 is slidably connected to the adjusting plate 93 through the sliding hole.

[0053] The bottom end of the one-way threaded shaft 92 is rotatably connected to the top of the main push plate 7, and the top end of the one-way threaded shaft 92 is connected to an adjusting turntable 96.

[0054] The rotating connecting seat 95 is composed of a central shaft and side plates. Both ends of the central shaft are connected to side plates. The surface of the central shaft is rotatably connected to the adjusting plate 93. The side plates are respectively connected to the corresponding adjusting plate 93 or side push plate 8.

[0055] In use, depending on the shape of the irregularly shaped cardboard box, rotate the adjusting turntable 96, thereby driving the one-way threaded shaft 92 to rotate, which in turn drives the adjusting plate 93 to move up or down along the fixed guide post 91. When the adjusting plate 93 moves, it drives the corresponding rotating connecting seat 95 to move in the same direction, thereby causing the connecting support bar 94 to rotate, which in turn drives the rotating connecting seat 95 below to move laterally, thereby driving the side push plate 8 to move in the same direction, so that the side push plates 8 on both sides move away from or closer to the main push plate 7. This expands the area of ​​the pushing surface formed by the side push plate 8 and the control component 9 to accommodate irregularly shaped cartons of different sizes. In other words, when the irregularly shaped cartons are small, the side push plates 8 are close to the main push plate 7, resulting in a smaller pushing surface. At this time, the pushing and pulling resistance of the side push plates 8 and the control component 9 is small, which saves more energy. When the irregularly shaped cartons are large, the side push plates 8 are far away from the main push plate 7, resulting in a larger pushing surface. This avoids the irregularly shaped cartons from moving at different positions on both sides due to a small pushing surface, and prevents the irregularly shaped cartons from tilting and affecting subsequent processes.

[0056] The side push plate 8 is slidably connected to the main push plate 7 via a sliding limiting component 12. The sliding limiting component 12 includes a sliding connecting post 121. A plurality of sliding connecting posts 121 are connected to the side of the side push plate 8 near the main push plate 7. The surface of the sliding connecting post 121 is slidably connected through the side of the main push plate 7. The end of the sliding connecting column 121 away from the side push plate 8 is connected to one side of the anti-detachment plate 122, and the anti-detachment plate 122 is slidably disposed in the inner cavity of the main push plate 7.

[0057] In this technical solution, the movement trajectory of the side push plate 8 is limited by the sliding limit component 12.

[0058] When in use, the side push plate 8 moves, causing the sliding connecting column 121 to move in the same direction, which in turn causes the anti-detachment plate 122 to move in the inner cavity of the main push plate 7, so that the side push plate 8 can only move in a straight line in the direction away from or close to the main push plate 7.

[0059] A positioning component 13 is slidably disposed between the mounting bracket 6 and the fixed bracket 4. The positioning component 13 includes an anti-deviation shaft 131. Multiple anti-deviation shafts 131 are connected to the side of the mounting bracket 6 near the fixed bracket 4. The surface of the anti-deviation shaft 131 is slidably connected to the fixed bracket 4. The end of the anti-deviation shaft 131 away from the mounting bracket 6 is connected to the positioning connecting plate 132.

[0060] In this technical solution, the movement trajectory of the mounting bracket 6 is limited by the positioning component 13.

[0061] When the mounting bracket 6 moves, it drives the anti-deviation shaft 131 to move in the same direction, which in turn drives the positioning connecting plate 132 to move in the same direction, thereby limiting the movement trajectory of the mounting bracket 6 and providing auxiliary support for the mounting bracket 6 and other structures, increasing the stability of the mounting bracket 6 and other structures.

[0062] The blocking assembly 10 includes a lifting device 101, and a blocking plate 102 is connected to the bottom output end of the lifting device 101. The top of the lifting device 101 is mounted on the bottom of the mounting plate 103.

[0063] In this technical solution, the blocking component 10 blocks the irregularly shaped cardboard box.

[0064] In use, the lifting device 101 drives the blocking plate 102 to move down, thereby blocking one end of the irregularly shaped cardboard box. Then, the push-pull device 5 drives the mounting frame 6 to move, thereby driving the control component 9, the main push plate 7 and the side push plate 8 to move. The main push plate 7 and the side push plate 8 push the irregularly shaped cardboard box from the other end, so that multiple irregularly shaped cardboard boxes are accurately stacked together.

[0065] When the stacked irregularly shaped cardboard boxes meet the requirements, i.e., according to the quantity or time, the lifting device 101 drives the blocking plate 102 to move upward. At this time, the conveyor belt of the pneumatic gluing unit 3 drives the stacked irregularly shaped cardboard boxes to move and enter the pneumatic component. The pneumatic pressure is used to squeeze the stacked irregularly shaped cardboard boxes, so that the glue adheres to the irregularly shaped cardboard boxes, thus achieving the gluing of the irregularly shaped cardboard boxes.

[0066] The synchronous control component 11 includes a fixed side plate 111 and a bidirectional threaded shaft 112. The top of the pneumatic paste box unit 3 is connected to two symmetrically distributed fixed side plates 111, and the bidirectional threaded shaft 112 is rotatably connected to the two fixed side plates 111. One end of the bidirectional threaded shaft 112 is connected to a rotary power source 113, which is installed on the top of the pneumatic paste box unit 3. Two symmetrically distributed movable plates 114 are threadedly connected to the surface of the bidirectional threaded shaft 112, and each of the two movable plates 114 is connected to an installation strip 103 on one side.

[0067] In this technical solution, the distance between the two blocking components 10 is adjusted by the synchronous control component 11 to accommodate irregularly shaped paper boxes of different widths.

[0068] A plurality of limiting posts 115 are connected between the two fixed side plates 111, and the surface of the limiting posts 115 is slidably connected through the movable plate 114.

[0069] In this technical solution, the movement trajectory of the moving plate 114 is limited by the limiting post 115.

[0070] In use, depending on the width of the irregularly shaped cardboard box, the rotating power source 113 drives the bidirectional threaded shaft 112 to rotate, thereby driving the moving plates 114 on both sides to move towards or away from each other along the limiting post 115, which in turn drives the corresponding mounting strip 103 to move in the same direction, thereby driving the lifting device 101 and the blocking plate 102 to move in the same direction. At this time, the two side baffles 102 can move towards each other or away from each other, thereby adjusting the width between the two baffles 102 to accommodate irregularly shaped paper boxes of different widths.

[0071] The positioning push-block unit also includes a limiting guide mechanism, which includes a mounting shaft 14. Both ends of the mounting shaft 14 are connected to support frames 15, and the bottom of the support frames 15 is connected to the pneumatic paste box unit 3. The mounting shaft 14 has two symmetrically distributed side-pushing components 16 and two symmetrically distributed guide components 17 mounted on its surface.

[0072] In this technical solution, the irregularly shaped paper box is guided by a limiting guide mechanism, which facilitates the positioning of the irregularly shaped paper box and its entry into the pneumatic gluing unit 3 for compression.

[0073] The side push assembly 16 includes a sliding block 161, which is slidably mounted on the surface of the mounting shaft 14. The sliding block 161 is slidably connected to the surface of the mounting post 162. A locking bolt 163 is threadedly connected to one side of the sliding block 161, and one end of the locking bolt 163 abuts against the surface of the mounting post 162. The end of the mounting post 162 away from the sliding block 161 is connected to the finite side plate 164.

[0074] In this technical solution, the side push components 16 on both sides limit the position of the irregularly shaped paper box, further assisting in the positioning of the irregularly shaped paper box.

[0075] In use, the position of the mounting post 162 can be locked by the locking bolt 163, so that the mounting post 162 can drive the edge limiting plate 164 to move, thereby adjusting the height of the edge limiting plate 164, etc. The side limit plates 164 on both sides can assist in positioning the irregularly shaped cardboard box from both sides.

[0076] The guide assembly 17 includes a mounting block 171, which is slidably mounted on the surface of the mounting shaft 14. The mounting block 171 is slidably connected to the surface of the adjusting column 172. A fastening bolt 173 is threadedly connected to one side of the mounting block 171, and one end of the fastening bolt 173 abuts against the surface of the adjusting column 172. A roller 174 is installed at the end of the adjusting column 172 away from the mounting block 171.

[0077] In this technical solution, the irregularly shaped paper box is guided by the guide component 17 to facilitate its movement.

[0078] The position of the adjusting column 172 can be locked by using the fastening bolt 173, so that the adjusting column 172 can drive the rolling wheel 174 to move, thereby adjusting the height of the rolling wheel 174 and other parameters.

[0079] The fixed central shaft end face of the rolling wheel 174 is connected to the adjusting column 172, and the rotating wheel body is rotatably sleeved on the outer surface of the fixed central shaft.

[0080] The sliding block 161 and the mounting shaft 14, as well as the mounting block 171 and the mounting shaft 14, are positioned by friction between them, thus preventing the sliding block 161 and the mounting block 171 from sliding or rotating along the mounting shaft 14.

[0081] The push-pull device 5 and the lifting device 101 are electric push rods, lifting cylinders, hydraulic lifting cylinders, or other devices with linear drive functions.

[0082] The rotary power source 113 is an electric motor or other device that can output rotational kinetic energy.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but all such changes and modifications fall within the scope of protection of the present invention.
