Description

TECHNICAL FIELD

[0001] The application relates to a honeycomb panel production method. BACKGROUND

[0002] The honeycomb panel is composed of a first panel, a second panel and a honeycomb core. In order to quickly dry the honeycomb panel and reach the standard water content, the honeycomb core is separately compounded with the first panel and the second panel and dried, so that the drying efficiency is greatly improved. However, there are still some problems in the separate compounding. Due to many external disturbances, such as different tension control of the first panel and the second panel, different sizes of the winding drum, different loads, different front and rear traction forces, and machining errors, the linear speed of the first panel and the second panel is different, the single-sided honeycomb panel compounded with the first panel and the honeycomb core cannot be synchronized with the second panel, the conveying speed of the single-sided honeycomb panel is faster than that of the second panel, the single-sided honeycomb panel is too loose relative to the second panel, and problems such as deviation, wrinkling, rupture and uneven glue coating occur. If the conveying speed of the single-sided honeycomb panel is slower than that of the second panel, the single-sided honeycomb panel will be pulled off by the traction force during the secondary compounding. Therefore, the speed difference between the front and the rear not only causes the single-sided honeycomb panel and the second panel to be not firmly bonded, but also causes the single-sided honeycomb panel to be broken, and it is impossible to realize high-speed production of the honeycomb panel.

[0020] The relevant details and working principles of the embodiments and examples of the present application are described below in conjunction with the drawings. The processing equipment for the honeycomb plate comprises a single-face forming mechanism and a double-face forming mechanism, a single-face honeycomb plate storage station 7 is arranged between the single-face forming mechanism and the double-face forming mechanism, the single-face forming mechanism and the double-face forming mechanism independently work, the storage station is provided with a conveying belt 15, the conveying speed of the conveying belt is slower than the forming speed of the single-face forming mechanism, the single-face forming mechanism comprises a first panel frame 1, a honeycomb core pulling device 3, a first gluing device 4 and a first compounding device 5, a material shaft is arranged on the first panel frame, a first panel roll is arranged on the material shaft, the double-face forming mechanism comprises a second panel frame, a second gluing device 12 and a second compounding device 13, a second panel roll is arranged on the material shaft of the second panel frame, along the conveying direction of the honeycomb core, the storage station 7 is arranged between the first compounding device 5 and the second gluing device 12.The honeycomb core pulling device 3 of the single-sided forming mechanism pulls the core board open to form a honeycomb core. One end face of the honeycomb core is coated with adhesive by the first adhesive applicator 4 and then enters the first composite device 5 with the first panel for lamination and drying to form a single-sided honeycomb panel. The second adhesive applicator 12 of the double-sided forming mechanism applies adhesive to the other end face of the single-sided honeycomb panel 8 that is not coated with adhesive. The coated single-sided honeycomb panel and the second panel 11 enter the second composite device for lamination and drying to form a double-sided honeycomb panel. After the honeycomb core and the first panel are laminated to form a single-sided honeycomb panel 8, the panel enters the storage area. On the conveyor belt at the workstation, because the conveyor belt speed is slower than the forming speed of the single-sided honeycomb panel, the material at the front of the conveyor belt will block the material entering from the rear, causing the single-sided honeycomb panel to arch upwards to form a storage area. As material continues to be input from the rear, the single-sided honeycomb panel arches to a certain height and then moves downwards. This continues, and the single-sided honeycomb panel accumulates on the conveyor belt in an undulating wave-like pattern. Guide rollers or arc-shaped guide plates can also be added to guide the single-sided honeycomb panel at the storage station, so that the single-sided honeycomb panel accumulates on the conveyor belt in an undulating wave-like pattern; the single The single-sided honeycomb panels are stacked and stored at storage station 7, where natural dehumidification takes place. The storage of single-sided honeycomb panels ensures that the single-sided forming mechanism and the double-sided forming mechanism operate independently and without interference. The traction force between the first panel 2 and the honeycomb core comes from the traction force during the first lamination, while the traction force between the second panel 11 and the single-sided honeycomb panel comes from the traction force during the second lamination. Thus, even if the linear velocities of the first and second panels are different, it will not directly affect the operation of the single-sided and double-sided forming mechanisms. Therefore, the gluing and traction of the single-sided honeycomb panel in the double-sided forming mechanism, as well as the traction of the second panel, are not affected by the single-sided forming mechanism. In other words, the single-sided honeycomb panel is not affected by forces in the front and rear directions during the gluing process, but only by the traction force of the front double-sided forming mechanism. Moreover, the main traction force it receives is the same as that of the second panel, and the speed is also the same. Therefore, the single-sided honeycomb panel will not shift or break during gluing, the gluing is uniform, and the single-sided honeycomb panel and the second panel are synchronized during lamination. The final double-sided honeycomb panel has strong strength and good quality. When the first panel needs to be changed, the double-sided forming mechanism can continue operating because there is sufficient material at the material storage station. Similarly, when the second panel needs to be changed, the single-sided forming mechanism can continue operating, achieving non-stop production of honeycomb panels and improving production efficiency. The honeycomb core pulling device, the first gluing device, the first laminating device, the second gluing device, and the second laminating device are all electrically connected to the electrical controller. This invention can also adjust the speed of the single-sided or double-sided forming mechanism according to the amount of material stored at the material storage station. For example, if there is too much material, the speed of the single-sided forming mechanism can be reduced, and vice versa, so that the amount of material stored at the material storage station is within the set range. Because there is a certain amount of material stored, there is sufficient adjustment time, which will not affect the overall processing speed of the equipment. Therefore, the speed can be increased to achieve high-speed production.The storage station can also serve as a natural moisture removal and drying area for the single-faced honeycomb panel 8, improving the drying effect. Compared with the prior art, the present application not only uniformly applies glue and firmly composites, but also has better drying effect, good quality of the formed honeycomb panel, and realizes high-speed production, greatly improving the production efficiency.

[0021] In order to improve the composite effect and precision, a deviation correcting device 9 is arranged between the storage station and the second glue applying device of the double-faced forming mechanism when the single-faced honeycomb panel enters the secondary composite station. The deviation correcting device can adopt a guide roller that can swing and a position sensor. The position sensor and a power member that drives the guide roller to swing are connected with an electrical controller. The position sensor can adopt infrared rays. When the position sensor detects that the position of the single-faced honeycomb panel deviates, the electrical controller sends an instruction to the power member to drive the guide roller to swing, so that the single-faced honeycomb panel moves in the opposite direction of the deviation, and then returns to the normal path. The deviation correcting device can also adopt a side baffle. The single-faced honeycomb panel moves forward along the side baffle, so that the second panel is aligned with the single-faced honeycomb panel, improving the precision of the composite and reducing the generation of waste materials.

[0022] In order to reduce the amount of glue, improve the compressive strength of the honeycomb panel, shorten the length of the equipment, and facilitate the arrangement of the equipment, a turning station is arranged between the first composite device and the storage station. The first glue applying device and the second glue applying device each include a glue applying roller. The glue applying part of the single-faced honeycomb panel or the honeycomb core is arranged above the glue applying roller. That is, the first face of the honeycomb core with the downward direction is glued with the first panel to form a single-faced honeycomb panel. At this time, the second face of the honeycomb core with the upward direction is not glued. The single-faced honeycomb panel is turned upward at the turning station, so that the second face of the single-faced honeycomb panel is downward, and the first face of the single-faced honeycomb panel that has been compositely formed with the first panel is upward. At this time, the glue applying roller of the second glue applying device applies glue to the second face of the single-faced honeycomb panel. Then, the single-faced honeycomb panel is compositely formed with the second panel to form a double-faced honeycomb panel. The first face and the second face of the honeycomb core are both glued from below. In this way, the glue does not enter the honeycomb holes when the glue is applied, reducing the amount of glue and the water content of the honeycomb core. Therefore, the drying speed is fast, the efficiency is high, and the energy consumption is low. Moreover, the glue adhering part 26 of the formed double-faced honeycomb panel is in the shape of an "I" letter. Figure 3As shown, not only the honeycomb core and panel is firmly bonded, but also the bonding part of the shaped double-sided honeycomb panel is symmetrical up and down, the compression strength is uniform, not easy to bend, deformation, compression strength is stronger. In order to make the single-sided honeycomb plate stable, the turning device is provided on the turning station, which can adopt the turning guide plate, in the embodiment, the turning device includes a traction component 6, which includes an upwardly inclined upper conveying assembly and a lower conveying assembly, which can adopt upper conveying roller and lower conveying roller or upper conveying belt and lower conveying belt, etc., the single-sided honeycomb plate is pulled upward to the storage station 7 by the upper conveying belt and the lower conveying belt, the traction component actively feeds the single-sided honeycomb plate at the turning station, so that the single-sided honeycomb plate after turning enters the storage station in order. Because the first face and the second face of the honeycomb core are both coated with glue from below, and are both arranged downward when being compounded with the first panel and the second panel, in order to improve the compounding effect, the surface of the double-sided honeycomb panel is flat and not deformed, the second compounding device includes a box body and a compounding component arranged in the box body, the traditional compounding component adopts upper and lower pressure rollers, the compounding component includes an upper pressing assembly and a lower ironing plate 19 and a lower conveying belt 24 in pressure with the upper pressing assembly, the lower conveying belt is arranged in front of the lower ironing plate, the upper pressing assembly includes an upper conveying belt 18, the upper conveying belt is in pressure with the lower ironing plate for high temperature ironing and pressing, so that the honeycomb core and the panel are firmly bonded and quickly dried, the upper conveying belt 18 and the lower conveying belt 14 are in pressure, which is pulled in front, because the lower ironing plate 19 directly contacts with the compounded panel, the surface of the panel is flat, which is more beneficial to printing and use as outer packaging; more importantly, the area of the lower ironing plate is large, the surface flatness is not as good as the pressure roller and the small area pressure block, and the weight of the lower ironing plate is relatively heavy, which is not convenient to float, is suitable for fixed installation, the thickness of the single-sided honeycomb panel and the double-sided honeycomb panel is not completely consistent during compounding, there is a certain error, and the surface of the lower ironing plate cannot be absolutely flat, if the distance between the upper conveying belt and the lower ironing plate is fixed, then the pressure received by each part of the continuously compounded honeycomb core and panel is not the same, the thinner part of the honeycomb panel is not compacted, so the bonding is not firm, the thicker part of the honeycomb panel may be damaged due to excessive compaction, in order to avoid the above problems and ensure that the honeycomb core and the panel are firmly compounded and not damaged, the upper pressing assembly further includes a pressure roller 20 in pressure with the lower ironing plate and the lower conveying belt, the pressure roller is floatingly arranged in the upper conveying belt 18, that is, the pressure roller 20 can correspondingly float according to the thickness of the single-sided honeycomb panel or the double-sided honeycomb panel during compounding, so as to adjust the distance between the upper conveying belt and the lower ironing plate, the lower conveying belt, in this way, the honeycomb core and the panel can be compacted at each position, so that they are firmly compounded, the surface of the panel is flat and not deformed, furthermore, due to the good compounding effect, the production speed can be improved. The lower conveying belt is provided with a lower pressure roller in pressure with the pressure roller, which avoids the slippage of the honeycomb panel and makes the honeycomb panel move stably forward.The floating of the pressing roller 20 can adopt active lifting. In the embodiment, the pressing roller is pressed on the honeycomb plate by its own weight, the pressing roller is installed on the swing arm 21 which is hinged to the frame, the pressing roller is pressed on the honeycomb plate by its own weight, and the pressing roller is up and down with the change of the thickness of the honeycomb plate, so that each part of the upper conveying belt is kept in pressure combined state with the lower ironing plate and the lower conveying belt. In this way, the honeycomb core and the face plate are uniformly stressed, the composite is firm, and the surface of the face plate is flat. The upper end of the swing arm is provided with a limiting piece, the limiting piece includes a nut 23 and a bolt 11 which is threadedly connected with the nut, the bolt penetrates through the nut and abuts against the upper end of the swing arm 21, the limiting piece prevents the pressing roller 20 from jumping and avoids the damage of the honeycomb plate, and the lowest height of the pressing roller when being pressed down can be adjusted by adjusting the position of the bolt. The pressing roller of the upper pressing assembly can also be replaced by a pressing plate, the upper pressing assembly further includes a pressing plate which is pressure combined with the lower ironing plate and the lower conveying belt, the pressing plate is arranged in the upper conveying belt, and the pressing plate can also adopt a floating structure, the pressing plate can be replaced by the pressing plate, and the contact area of the pressing plate is larger than that of the pressing roller when being pressure combined.

First, the first face plate frame and the second face plate frame are not stacked, but can be directly arranged on the ground, so that the operation is convenient and safe. Second, the face plate is close to the glue applying and composite station, so that the loss of changing specifications is reduced. Third, the storage station is arranged above the single-sided forming mechanism, so that the space is reasonably utilized, the natural drying time is prolonged, and the drying effect is effectively improved. Fourth, the length of the equipment is short, the occupied area is small, and the natural drying process is further added, so that the composite drying time can be shortened, the energy consumption is further reduced, and the length of the equipment is further shortened.

[0024] The processing equipment of the honeycomb plate further comprises a cross-cutting mechanism arranged in front of the honeycomb forming mechanism, which cuts the continuous double-sided honeycomb plate into unit honeycomb plates according to requirements after the double-sided honeycomb plate is formed; the traditional cross-cutting mechanism uses a circular knife to cut, that is, the circular knife is driven to move transversely to cut the continuous double-sided honeycomb plate into unit honeycomb plates, which has the problem of low efficiency; the present application has realized high-speed production of the honeycomb plate, and therefore the traditional circular knife cutting will affect the production efficiency; of course, the use of double-station cutting will improve the cross-cutting efficiency, but will increase the length of the equipment and the production cost; therefore, the cross-cutting mechanism is improved in the present application, which comprises an upper knife 30 and a lower knife 28 that engage with each other, the upper knife is installed on an upper roller 29, the lower knife is installed on a lower roller 31, the upper and lower rollers rotate synchronously, and the upper and lower knives engage to cut the double-sided honeycomb plate; compared with the existing cross-cutting mechanism, the cross-cutting speed of the present application is fast and suitable for high-speed production; and the present application can cut unit honeycomb plates of different lengths by adjusting the rotating speed of the upper and lower rollers; for example, under the condition that the speed of the honeycomb plate traction is consistent, the faster the rotating speed of the upper and lower rollers, the shorter the length of the cut unit honeycomb plate, and vice versa, the slower the rotating speed of the upper and lower rollers, the longer the length of the cut unit honeycomb plate.
