Description

Technical Field

[0001] This invention relates to the field of auxiliary technology for cardboard box processing, specifically a multifunctional auxiliary workbench for cardboard box processing. Background Technology

[0002] Cardboard box processing refers to the complete production process of turning raw paper into corrugated cardboard through a series of processes, and further processing it into various types of cardboard boxes. The cardboard box processing process is mostly as follows: first, cutting the corrugated cardboard; then, creasing the cardboard with a creasing machine; then, applying glue to the glued areas; then, gluing the glued areas; then, folding it into the original shape of the cardboard box; and finally, sealing the opening. In the process of applying glue to the bonded areas of cardboard, the existing technology uses a sensor to sense the passage of the cardboard and triggers the glue application mechanism to apply glue to the cardboard. Its working principle is to convey the cardboard through a conveyor belt. When the cardboard is conveyed to the bottom of the glue dispensing head, the sensor controls the glue dispensing head to dispense glue, so as to apply glue to a large number of cardboards one by one. Existing gluing technologies integrate conveying mechanisms, sensing mechanisms, and gluing modules to achieve intelligent and efficient cardboard gluing operations. Their automated processes significantly improve production speed while simplifying operation. However, when processing cardboard of varying thicknesses, this technology cannot adaptively adjust the glue output based on the cardboard's thickness. Specifically, for thin cardboard, a fixed glue output can easily lead to excessive glue penetration, causing structural deformation or reduced bonding strength. Conversely, with thick cardboard, a constant glue output may not adequately cover the contact surface. Because of the constant glue output, the amount may be too small, requiring more glue for thicker cardboard (i.e., repeated coverage of the contact surface with more glue), resulting in weak adhesion. This makes it difficult to balance gluing precision and material properties.

[0003] To address the above problems, this invention proposes a multifunctional auxiliary workbench for cardboard box processing. Summary of the Invention

[0004] The present invention addresses the problem of overly simplistic solutions in existing technologies by providing a significantly different solution. Specifically, the present invention aims to provide a multifunctional auxiliary workbench for carton processing, thereby solving the problem mentioned in the background that the glue output cannot be adaptively adjusted according to the thickness of the cardboard.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a multi-functional auxiliary workbench for cardboard box processing, comprising a work frame, a conveying mechanism disposed inside the work frame for conveying cardboard, a frame fixed to the top of the work frame, and an adhesive applicator disposed above the conveying mechanism, and further comprising: The first triggering component is located inside the frame and above the conveying mechanism. The first triggering component includes an elastic element connected to the top of the frame. When the cardboard passes through the first triggering component, the first triggering component moves up and down adaptively according to the thickness of the cardboard under the elastic force of the elastic element. The first transmission component is located between the first trigger component and the glue application component, and is used to transmit the force of the lifting and lowering movement of the first trigger component to the glue application component and control the glue dispensing pressure. A sealing component, located at the output port of the adhesive applicator, is used to control the size of the adhesive outlet. The second triggering component is located beside the glue coating component and above the conveying mechanism. The second triggering component includes an elastic element connected to the glue coating component. When the cardboard passes through the second triggering component, the second triggering component moves up and down adaptively according to the thickness of the cardboard under the elastic force of the elastic element. The second transmission component is located between the second trigger component and the sealing component, and is used to transmit the force of the lifting and lowering movement of the second trigger component to the sealing component.

[0006] Preferably, the first triggering component includes a first spring fixed to the inner wall of the frame, and a first cylinder is fixedly connected to the bottom of the first spring; The first piston rod is slidably sleeved inside the first cylinder, and the top of the first piston rod is fixedly connected to the inner wall of the frame. An indentation frame is fixedly connected to the bottom of the first cylinder body. The inner wall of the indentation frame is provided with a sealed bearing, and an indentation rod is fixedly installed inside the sealed bearing. The outer wall of the indentation rod is fixedly fitted with a first indentation wheel.

[0007] Preferably, a second cylinder is fixedly connected to the outer wall of the first indentation wheel, a second piston rod is slidably sleeved inside the second cylinder, and one end of the second piston rod is fixedly connected to the second indentation wheel; A through groove is provided on one side of the second indentation wheel, and the inner wall of the through groove is slidably connected to the outer wall of the indentation rod.

[0008] Preferably, the indentation frame has an oil storage channel inside, and the indentation rod has an oil groove inside, with the oil storage channel communicating with the oil groove; The inner walls of the first cylinder and the second cylinder are provided with oil inlets, and the two oil inlets are respectively connected to the oil storage channel and the first indentation wheel.

[0009] Preferably, the first transmission assembly includes a lifting rod and an oil cylinder, wherein the lifting rod is in the shape of an "L" shape; One end of the lifting rod extending outside the oil cylinder is fixedly connected to one side of the indentation frame.

[0010] Preferably, the adhesive application assembly includes an adhesive storage cylinder, an adhesive dispensing pipe, and a pressure adhesive container, wherein the inner wall of the oil cylinder has an opening that communicates with the adhesive storage cylinder.

[0011] Preferably, a lifting plate is slidably provided on the inner wall of the glue storage cylinder; A second spring is fixedly connected to the bottom of the lifting plate, and a negative pressure plate is fixedly connected to the bottom of the second spring. The outer wall of the negative pressure plate is slidably connected to the inner wall of the glue storage cylinder.

[0012] Preferably, the second transmission assembly includes a third spring connected to the outer wall of the dispensing tube, and one end of the third spring is fixedly connected to a displacement plate; A displacement rod is fixedly connected to the bottom of the displacement plate, and one end of the displacement rod is fixedly connected to the outer wall of the sealing plate.

[0013] Preferably, the displacement plate has an arc-shaped structure, and the outer wall of the displacement plate is an inclined surface; The inner wall of the sealing plate is curved.

[0014] Preferably, the second triggering component includes a limiting plate fixedly sleeved on the outer wall of the dispensing tube; A fourth spring is fixedly connected to the bottom of the limiting plate, and a limiting ring is fixedly connected to the bottom of the fourth spring. The limiting ring is slidably sleeved on the outer wall of the displacement plate; The guide plate is fixedly mounted on the outer wall of the limiting ring, and the roller is rotatably connected to the end of the guide plate away from the dispensing tube.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. When the cardboard passes through the rollers, its thickness difference triggers the vertical displacement of the limiting ring. This displacement is converted into a change in the opening and closing degree of the glue-blocking plate. Specifically, thicker cardboard will push the limiting ring to move upwards more significantly. At this time, the displacement ring and the displacement plate form a larger angle, and the displacement plate has a larger displacement space, creating a wider glue flow channel between the two glue-blocking plates. The pressurization effect of the oil cylinder is simultaneously enhanced, accelerating the glue flow. Conversely, thinner cardboard will cause the channel to narrow and the flow rate to decrease. This closed-loop control based on thickness-pressure-flow rate makes the glue output precisely positively correlated with the cardboard thickness. Compared with the existing technology, it has the advantage of being able to adaptively adjust the glue amount according to the cardboard thickness, and will not cause problems such as cardboard penetration or weak adhesion due to improper glue amount. Through the dynamic compensation of the negative pressure plate, the best coating effect can be achieved for cardboard of different thicknesses.

[0016] 2. When the cardboard passes through the creasing frame, the cardboard has thickness. The first and second creasing wheels drive the creasing frame and the first cylinder to move upward. The first piston rod squeezes the oil at the bottom of the first cylinder, causing some of the oil to enter the oil tank through the oil storage channel. Then, it enters the second cylinder through the first creasing wheel. The increase in oil in the second cylinder pushes the second piston rod, thereby driving the second creasing wheel to move. The distance between the first and second creasing wheels increases, and the creasing marks on the cardboard also become wider. This allows for adaptive adjustment of the creasing spacing according to the thickness of the cardboard, facilitating subsequent folding processes. Attached Figure Description

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1 to 11 This invention provides a technical solution: a multi-functional auxiliary workbench for cardboard box processing, comprising a work frame 1, cardboard 3, a conveying mechanism 2 disposed inside the work frame 1, a pressure glue tank 8 disposed on the outer wall of the work frame 1, and a frame 4 fixed to the top of the work frame 1, and further comprising: A flat pressing component installed inside the frame 4 that adaptively adjusts the indentation width based on the thickness of the cardboard 3; The mounting bracket is fixed to the top of the frame 4, and the oil cylinder 6 and glue storage cylinder 62 are fixed to the inner wall of the mounting bracket; The lifting rod 61 slides inside the oil cylinder 6 and the dispensing pipe 7 is fixed to the bottom of the oil cylinder 6; A negative pressure component installed inside the glue storage cylinder 62 to adaptively adjust the glue flow rate based on the thickness of the cardboard 3; A glue-blocking plate 74 is set at the bottom of the glue dispensing tube 7 to control the glue dispensing, and an induction switch component is set outside the glue dispensing tube 7 to adaptively adjust the glue dispensing capacity based on the thickness of the cardboard 3. The inductive switch component includes a roller 79 that senses changes in the thickness of the cardboard 3 and automatically controls the opening degree of the glue-blocking plate 74.

[0031] In the specific implementation, both the conveying mechanism 2 and the pressure glue tank 8 are existing devices and will not be explained in detail here. The cardboard 3 is placed on the conveying mechanism 2, and the conveying mechanism 2 will convey the cardboard 3. The pressure glue tank 8 stores glue liquid inside. The pressure glue tank 8 is equipped with a glue supply pipe, which extends into the glue storage cylinder 62 and is fixedly connected to the glue storage cylinder 62. The pressure glue tank 8 supplies glue liquid into the glue storage cylinder 62 through the glue supply pipe. It should be noted that one-way valves are respectively installed on the glue inlet side and glue outlet side of the supply pipe, so that the movement direction of the glue liquid in the supply pipe can be moved as needed.

[0032] The flattening component includes a first spring 41 fixed to the inner wall of the frame 4, and a first cylinder 42 is fixedly connected to the bottom of the first spring 41. The first piston rod 43 is slidably sleeved inside the first cylinder 42, and the top of the first piston rod 43 is fixedly connected to the inner wall of the frame 4. An indentation frame 44 is fixedly connected to the bottom of the first cylinder body 42. The inner wall of the indentation frame 44 is provided with a sealed bearing, and an indentation rod 5 is fixedly installed inside the sealed bearing. The outer wall of the indentation rod 5 is fixedly fitted with a first indentation wheel 51.

[0033] In a specific implementation, the first piston rod 43 is composed of a vertical rod and a sealing piston. The sealing piston slides inside the first cylinder 42. When the cardboard 3 passes through the creasing frame 44, the first creasing wheel 51 creasing the cardboard 3.

[0034] The outer wall of the first indentation wheel 51 is fixedly connected to the second cylinder 52, and the second piston rod 53 is slidably sleeved inside the second cylinder 52. One end of the second piston rod 53 is fixedly connected to the second indentation wheel 54. The second indentation wheel 54 has a through groove on one side, and the inner wall of the through groove is slidably connected to the outer wall of the indentation rod 5.

[0035] In practice, the first crease wheel 51 is fixed to the outside of the crease rod 5, and the second crease wheel 54 slides to the outside of the crease rod 5. When the position of the second crease wheel 54 is adjusted on the crease rod 5, the distance between the first crease wheel 51 and the second crease wheel 54 will change, and thus the crease spacing of the cardboard 3 will also change.

[0036] The indentation frame 44 has an oil storage channel 45 inside, and the indentation rod 5 has an oil groove 55 inside. The oil storage channel 45 communicates with the oil groove 55. The inner walls of the first cylinder 42 and the second cylinder 52 are provided with oil inlets, and the two oil inlets are respectively connected to the oil storage channel 45 and the first indentation wheel 51.

[0037] In specific implementation, the interior of the first embossing wheel 51 is hollow and communicates with the oil tank 55. When the first embossing wheel 51 embosses the cardboard 3, the thickness of the cardboard 3 drives the embossing frame 44 to move upward, so that the sealed piston on the first piston rod 43 squeezes the oil inside the first cylinder 42. The oil can enter the interior of the second cylinder 52 through the oil storage channel 45 and the oil tank 55. The oil squeezes the second piston rod 53, and the end of the second piston rod 53 extending out of the second cylinder 52 pushes the second embossing wheel 54, thereby adjusting the position of the second embossing wheel 54.

[0038] The lifting rod 61 has an "L" shaped structure; One end of the lifting rod 61 extending outside the oil cylinder 6 is fixedly connected to one side of the indentation frame 44.

[0039] In a specific implementation, a sealing piston is provided at the top of the lifting rod 61, and the sealing piston slides inside the oil cylinder 6. When the indentation frame 44 moves upward, it will drive the lifting rod 61 to move. When the lifting rod 61 moves upward, the end extending into the oil cylinder 6 will squeeze the oil inside the oil cylinder 6.

[0040] The inner wall of the oil cylinder 6 has an opening, which communicates with the glue storage cylinder 62.

[0041] In practice, the oil inside the oil cylinder 6 enters the interior of the glue storage cylinder 62 through the port.

[0042] The negative pressure component includes a lifting plate 63 that is slidably connected to the inner wall of the glue storage cylinder 62; The bottom of the lifting plate 63 is fixedly connected to a second spring 64, and the bottom of the second spring 64 is fixedly connected to a negative pressure plate 65. The outer wall of the negative pressure plate 65 is slidably connected to the inner wall of the glue storage cylinder 62.

[0043] In practice, when the oil inside the oil cylinder 6 enters the glue storage cylinder 62 through the port, the oil will squeeze the lifting plate 63, causing the second spring 64 to compress. When the glue blocking plate 74 no longer blocks the glue outlet pipe 7, the negative pressure plate 65 will quickly squeeze out the glue through the elastic force of the second spring 64, thereby increasing the glue output and flow rate.

[0044] A third spring 71 is fixedly installed on the outer wall of the dispensing tube 7, and a displacement plate 72 is fixedly connected to one end of the third spring 71. A displacement rod 73 is fixedly connected to the bottom of the displacement plate 72, and one end of the displacement rod 73 is fixedly connected to the outer wall of the sealing plate 74.

[0045] In practice, the third spring 71 is in a compressed state, and the two glue-blocking plates 74 can block the bottom of the glue outlet tube 7. When the two glue-blocking plates 74 move in opposite directions and leave a gap between them, the glue can be discharged.

[0046] The displacement plate 72 has an arc-shaped structure, and the outer wall of the displacement plate 72 is a slope. The inner wall of the sealing plate 74 is curved.

[0047] In practice, when the adhesive is discharged through the gap between the adhesive blocking plates 74, it is discharged along the inner wall of the adhesive blocking plates 74. The inner wall of the adhesive blocking plates 74 is inclined, so when the adhesive is discharged, there will be no large amount of adhesive residue inside the dispensing pipe 7.

[0048] The inductive switch component also includes a limiting plate 75 that is fixedly sleeved on the outer wall of the dispensing tube 7; A fourth spring 76 is fixedly connected to the bottom of the limiting plate 75, and a limiting ring 77 is fixedly connected to the bottom of the fourth spring 76. The limiting ring 77 is slidably sleeved on the outer wall of the displacement plate 72; The guide plate 78 is fixedly mounted on the outer wall of the limiting ring 77, and the roller 79 is rotatably connected to the end of the guide plate 78 away from the dispensing tube 7.

[0049] In practice, the roller 79 rolls on the cardboard 3, which causes the limiting ring 77 to move upward. There is a gap between the outer wall of the displacement plate 72 and the limiting ring 77. The elastic force of the third spring 71 causes the displacement plate 72 to move. At this time, the displacement plate 72 can drive the glue-blocking plate 74 to move through the displacement rod 73, so that the two glue-blocking plates 74 move in opposite directions. The glue is discharged through the gap and falls onto the cardboard 3, thus achieving glue application.

[0050] Working principle: When using this multi-functional auxiliary workbench for cardboard box processing, first start the conveyor mechanism 2, place the cardboard 3 to be processed on the conveyor mechanism 2, and the conveyor belt of the conveyor mechanism 2 will transport the cardboard 3. When the cardboard 3 passes through the creasing frame 44, the first creasing roller 51 and the second creasing roller 54 creasing the cardboard 3. Due to the thickness of the cardboard 3, the first creasing roller 51 and the second creasing roller 54 will move upward a certain distance, thus driving the creasing frame 44 and the first cylinder 42 to move upward. The first piston rod 43 squeezes the oil at the bottom of the first cylinder 42, causing some of the oil to enter the oil tank 55 through the oil storage channel 45, and then enter the second cylinder 52 through the first creasing roller 51. The increase in oil in the second cylinder 52 will push the second piston rod 53, thereby driving the second creasing roller 54 to move. The distance between the first creasing roller 51 and the second creasing roller 54 increases, and the mark pressed on the cardboard 3 also becomes wider (see reference). Figures 4-5 ); The thicker the cardboard 3 is creased by the first creased roller 51 and the second creased roller 54, the greater the upward movement of the creased frame 44, and the more oil is squeezed into the second cylinder 52. Therefore, the distance between the first creased roller 51 and the second creased roller 54 becomes larger. Conversely, when the cardboard 3 is relatively thin, the upward movement of the creased frame 44 is smaller, and less oil is squeezed into the second cylinder 52. Therefore, the movement distance of the second creased roller 54 is shorter. This allows for adaptive adjustment of the creased spacing according to the thickness of the cardboard 3, which is convenient for subsequent folding processes of the cardboard 3. When the indentation frame 44 moves upward, it will drive the lifting rod 61 to move together. The piston end of the lifting rod 61 squeezes the oil inside the oil cylinder 6 into the glue storage cylinder 62. The oil inside the glue storage cylinder 62 squeezes the lifting plate 63, and the lifting plate 63 squeezes the second spring 64. At this time, the negative pressure plate 65 is subjected to the elastic force of the second spring 64 and squeezes the glue inside the glue storage cylinder 62. The glue storage cylinder 62 and the glue outlet pipe 7 are both in a pressurized state. When one end of the cardboard 3 passes the roller 79, the roller 79 rolls on the cardboard 3 and drives the limiting ring 77 to move upward. After the limiting ring 77 moves upward a certain distance, there is a gap between the outer wall of the displacement plate 72 and the limiting ring 77. The elastic force of the third spring 71 drives the displacement plate 72 to move. At this time, the displacement plate 72 can drive the glue-blocking plate 74 to move through the displacement rod 73, so that the two glue-blocking plates 74 move in opposite directions. The glue liquid is discharged through the gap and falls onto the cardboard 3 to achieve glue application. When the two rollers 79 roll on the cardboard 3, they will leave micro-indentations. The two rollers 79 are located on both sides of the glue tube 7, so the micro-indentations are located on both sides of the glue application area. When there is a lot of glue, the micro-indentations can store and limit the excess glue, preventing the excess glue from spreading over a large area. Since the outer wall of the displacement plate 72 is inclined, the displacement plate 72 moves away from the glue outlet tube 7 as the limiting ring 77 moves upward. The opening between the two glue blocking plates 74 also increases at the same time. Therefore, the thicker the cardboard 3, the larger the gap for glue outlet, and the greater the glue flow rate due to the pressure of the negative pressure plate 65, resulting in a larger glue coating capacity. Conversely, the thinner the cardboard 3, the smaller the gap for glue outlet, the smaller the glue flow rate, and the smaller the glue coating capacity. This allows for adaptive adjustment of the glue outlet capacity according to the thickness of the cardboard 3. When the cardboard 3 is coated with glue and disengaged from the roller 79, the limiting ring 77 will be reset by the fourth spring 76. The inner wall of the limiting ring 77 moves the displacement plate 72 towards the outer wall of the glue outlet tube 7 along the inclined surface of the outer wall of the displacement plate 72. This causes the two glue blocking plates 74 to move in opposite directions and be in a closed state, so as to realize automatic control of glue discharge according to the position of the cardboard 3.

[0051] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
