Abstract

A mobile air-knife thermal rupture device based on honeycomb core panels belongs to the technical field of thermal rupture equipment. It includes a main frame, with an electrical cabinet controlling the internal electrical equipment on one side. The top two sides of the main frame are equipped with slide rails, and the interior of the main frame features a multi-layered reinforcing frame for support. The device is characterized by a first mounting frame for clamping the honeycomb core panels within the main frame. This first mounting frame consists of two sets of side beams and two sets of cross beams, with the two sets of side beams slidably positioned between the two sets of cross beams. This invention utilizes air-knife movement and panel fixation, resulting in a small footprint and adaptability to large-size panels. It abandons the traditional assembly line panel conveying mode, replacing it with a structure where the honeycomb core panels are fixed and clamped, and the thermal rupture air knife moves reciprocally.

Description

Technical Field

[0001] This invention belongs to the technical field of thermal rupture equipment for adhesive films, specifically relating to a mobile air knife thermal rupture equipment for adhesive films based on honeycomb core panels. Background Technology

[0002] Honeycomb core materials, with their lightweight, high specific strength, and excellent sound and heat insulation properties, are widely used in aerospace, rail transportation, shipbuilding, and architectural decoration. In the preparation of honeycomb sandwich panels, a carrier adhesive film is first applied to the surface of the honeycomb core material. Then, heating is used to soften and melt the film, ultimately allowing it to adhere evenly to the edges of the honeycomb cells, providing a reliable adhesive layer for subsequent bonding to the panel.

[0003] Currently, the hot rupture equipment for honeycomb films in the industry is mainly divided into two categories: one is the roller conveyor type hot rupture machine, which adopts a structure of continuous conveying of sheet materials and fixed arrangement of air knives. The honeycomb panels are driven by rollers to pass through the preheating zone and the hot rupture zone at a uniform speed to complete the processing. Although this type of equipment has a high degree of automation, it is limited by the length of the production line. When processing large-sized sheets, the overall equipment occupies a large area, and it cannot flexibly adapt to honeycomb core sheets of different widths and specifications, making changes and adjustments cumbersome.

[0004] Another type is oven-type or robotic thermal breaking equipment. Oven-type equipment has poor temperature control accuracy and uneven heating, which can easily lead to problems such as local over-curing of the film or insufficient film breaking. Although robotic equipment is highly flexible, it has high equipment cost, complex programming, and limited single-station operation efficiency, making it difficult to meet the continuous processing needs of medium and large batches of flat honeycomb cores.

[0005] In addition, most existing equipment only has a single-sided thermal rupture structure or lacks an independent preheating unit, resulting in insufficient softening of the adhesive film and insufficient uniformity of the adhesive film spread on the honeycomb edges after thermal rupture, which directly affects the bonding strength and product qualification rate of the final honeycomb sandwich panel.

[0017] The beneficial effects of this invention are as follows:

[0018] The air knife moves and the sheet is fixed, which takes up little space and is suitable for large-size sheets: It abandons the traditional assembly line sheet conveying mode and replaces it with a structure in which the honeycomb core sheet is fixed and clamped and the hot breaking air knife moves back and forth as a whole. There is no need for long-distance conveying lines, and the equipment footprint is significantly reduced; at the same time, it is not limited by the conveying length and can be adapted to the processing of large-size and wide honeycomb core sheets.

[0019] The first mounting frame consists of two sets of side beams and two sets of cross beams, with the side beams slidably positioned between the two sets of cross beams. This allows for adjustable tension clamping of panels of different sizes, flexibly adapting to multiple panel sizes. By opening adjustment slots at the mounting clamping components, the clamping spacing and tension can be quickly adjusted, making it compatible with various specifications and sizes of planar honeycomb core panels. It is easy to change types and has strong equipment versatility.

[0020] The combination of upper and lower air knife components, along with preheating with a quartz lamp, ensures superior thermal breaking quality: The lower air knife component structure applies hot air to the bottom of the honeycomb core panel, ensuring uniform heating of the adhesive film. The upper air knife component then spreads the thermally broken adhesive film evenly. Combined with preheating by a pre-positioned quartz lamp, the adhesive film gradually reaches its softening temperature. Finally, it undergoes melting and breaking through a precisely temperature-controlled hot air stream. The adhesive film is fully and evenly spread along the edges of the honeycomb structure, effectively avoiding defects such as over-curing or insufficient film breaking, resulting in a higher product qualification rate.

Detailed Implementation

[0032] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0033] Example 1: A mobile air-knife thermal rupture device for adhesive film based on honeycomb core panels, such as... Figures 1-10As shown, the system includes a main frame 1. An electrical cabinet 12 for controlling the internal electrical equipment is installed on one side of the main frame 1. The top two sides of the main frame 1 are slide rails. The main frame 1 has a multi-layer reinforcing frame 11 for support. The main frame 1 has a first mounting frame 2 for clamping the honeycomb core panel. The first mounting frame 2 is composed of two sets of side beams and two sets of cross beams. The two sets of side beams are slidably arranged between the two sets of cross beams. Multiple clamping components 3 and clamping accessories are installed on the first mounting frame 2 to clamp the honeycomb core panel. A rotating shaft 22 is provided in the middle of both sides of the first mounting frame 2. A first pushing component 6 is provided below the first mounting frame 2. The first pushing component 6 is located inside the main frame 1. The other side of the top of the main frame 1 has an empty compartment for placing the heating structure. A moving platform 4 is slidably arranged in this compartment via the top slide rail of the main frame 1. A heating unit 5 is installed on the top of the moving platform 4. The heating unit 5 moves toward the honeycomb core panel via the slide rail of the moving platform 4.

[0034] Based on the size of the honeycomb core panel to be processed, adjust the positional relationship between the crossbeams and side beams in the first mounting frame 2 and the position of each clamping component 323. Place the honeycomb core panel 25 covered with carrier adhesive film horizontally into the first mounting frame 2 and fix it by the clamping components 323 around the perimeter to ensure that the surface of the panel is flat and wrinkle-free.

[0035] Both sides of the main frame 1 are provided with crossbars 14 for supporting the first mounting frame 2. A side support frame 13 is provided on the side of the crossbar 14 closest to the main frame 1 to support the crossbar 14. The side support frame 13 is installed on the main frame 1. The crossbar 14 is installed on the side of the side support frame 13 and a first positioning clamp 141 is installed. A second positioning clamp 142 is provided at both ends of the crossbar 14. A longitudinal rod 15 is provided on the main frame 1 corresponding to the second positioning clamp 142. The two ends of the crossbar 14 are fixed to the longitudinal rod 15 through the second positioning clamp 142.

[0036] The first mounting frame 2 has an adjustment groove 21 for the movable clamping assembly 3 at the location where the clamping assembly 3 is installed. The clamping assembly 3 includes a fixed plate 31, a lead screw nut 34 in the middle section of the fixed plate 31, a first lead screw 33 inserted into the lead screw nut 34, a pin inserted laterally at one end of the first lead screw 33 to achieve rotation of the first lead screw 33, and one end of the first lead screw 33 extends through the adjustment groove 21 into the first mounting frame 2 and is provided with a movable plate 32. A lower clamping plate 37 is provided at the bottom of the movable plate 32, and an upper clamping plate 36 is provided above the lower clamping plate 37. First bolts 38 are provided through the upper clamping plate 36 and the lower clamping plate 37 on both sides, with the first bolts 38 pointing downwards. A wing nut 39 is sleeved on the top surface of the upper clamping plate 36. The lower clamping plate 37 is fixed, and the upper clamping plate 36 is slidably disposed on the surface of the first bolts 38. The height of the upper clamping plate 36 on the first bolt 38 is adjusted by turning the wing nut 39. Guide shafts 35 are respectively provided on both sides between the moving plate 32 and the fixed plate 31. One end of the guide shaft 35 is fixed on the moving plate 32, and the other end slides through the fixed plate 31 and the adjustment groove 21. The clamping surfaces of the upper clamping plate 36 and the lower clamping plate 37 are provided with a high-temperature resistant anti-slip rubber layer and positioning baffles to ensure that the clamping is reliable and to avoid damage to the edge of the honeycomb core board. The clamping accessories consist of the upper clamping plate 36 and the lower clamping plate 37, as well as the corresponding first bolt 38 and wing nut 39. The clamping accessories are directly fixed to the inside of the first mounting frame 2 through the lower clamping plate 37. The upper clamping plate 36 is installed on the lower clamping plate 37 by the first bolt 38 and the wing nut 39 to achieve the overall installation.

[0037] Material feeding and changing: After the thermal crushing is completed, the moving platform 4 is reset, the clamping component 3 is released, and the processed honeycomb core board is taken out. When changing to different sized boards, it is only necessary to adjust the position of the clamping component 3 and the position of the corresponding side beams between the cross beams to quickly change the shape. The crane completes the board replacement. At the same time, it can also work with the first pushing component 6 to move the entire first mounting frame 2 with the board outward and replace the entire first mounting frame 2 to achieve quick replacement. In this way, before the replacement, the board that needs to be thermally crushed can be installed on the new first mounting frame 2 at another station and clamped by the clamping component 3 and clamping accessories. The replacement effect will also be greatly accelerated.

[0038] A drive motor 41 is installed on the mobile platform 4. A first synchronous roller 43 is installed on the output end of the drive motor 41. Both sides of the first synchronous roller 43 are fitted with drive rollers 42. Multiple driven rollers 44 are installed on both sides of the mobile platform 4 corresponding to the drive rollers 42. The drive rollers 42 and driven rollers 44 are slidably mounted on slide rails on both sides of the top of the main frame 1. When the drive motor 41 is running, the friction transmission between the drive rollers 42 and the slide rails drives the entire mobile platform 4 to reciprocate at a uniform speed along the slide rails. This transmission method is stable, has low noise, and a wide speed adjustment range, allowing for flexible adjustment of the travel speed according to the thermal breaking process requirements of different film materials.

[0039] The heating unit 5 includes a second mounting frame 52 mounted on the mobile platform 4, which is interconnected with the mobile platform 4. A heat insulation plate 53 is installed on each side hole of the second mounting frame 52. A heating fan 51 is mounted on the top of the second mounting frame 52. A hot air main pipe 54 extends downward from the rear end of the heating fan 51. A first hot air box 55 is fitted onto the hot air main pipe 54 and is fixed to the side of the second mounting frame 52. Two secondary hot air short pipes 57 are inserted into the bottom of the first hot air box 55. Two secondary hot air short pipes 57 extend downwards from the mobile platform 4 to the bottom of the second mounting frame 52, bending and extending through the mobile platform 4 to the bottom of the second mounting frame 52. A second hot air box 58 is fitted onto the output end of each of the two secondary hot air short pipes 57. A material placement plate 515 is provided at the bottom of each of the two second hot air boxes 58 to support it. Multiple tertiary hot air pipes 59 are inserted into the front end of each of the two second hot air boxes 58, and a lower air knife assembly 516 is provided at the output end of each of the multiple tertiary hot air pipes 59. Multiple secondary hot air long pipes 56 are inserted into the front of the first hot air box 55. Each secondary hot air duct 56 has an upper air knife assembly 511 at its output end. The upper air knife assembly 511 and the lower air knife assembly 516 are staggered and separated by a space for the movement of the honeycomb core panel. The secondary hot air ducts 56 are inserted into the upper air knife assembly 511 in an evenly spaced manner. Similarly, the multiple tertiary hot air ducts 59 at the output end of each second hot air box 58 are also inserted into the lower air knife assembly 516 in an evenly spaced manner, making the incoming hot air more uniform and preventing it from becoming disordered. The secondary hot air short duct 57, the secondary hot air long duct 56, and the tertiary hot air ducts 59 are all flexible pipes for easy adjustment. The heating fan 51 is equipped with a heating ceramic resistance wire. Room temperature air is heated by the heating unit 5 to form hot air, which is then delivered to the upper air knife assembly 511 through the hot air main pipe 54, the first hot air box 55, and the second-stage hot air short pipe 57. Another set of hot air is delivered to the lower air knife assembly 516 through the second-stage hot air long pipe 56, the second hot air box 58, and the third-stage hot air pipe 59. The upper air knife assembly 511 is located above the honeycomb core board, and the lower air knife assembly 516 is located below the board. The two are positioned opposite each other and both adopt a strip-shaped narrow air outlet structure. The air outlet direction is perpendicular to the surface of the board, which can form a continuous hot air band with a thickness of about 2mm, which is precisely applied to the surface of the adhesive film.

[0040] Adjustment components are provided on both sides of the upper air knife assembly 511, the lower air knife assembly 516, and the material placement plate 515. The adjustment components include a screw adjustment seat 512 on the side of the second mounting frame 52, a second screw 513 is inserted into the screw adjustment seat 512, and a pin is horizontally inserted into the top of the second screw 513. The second screw 513 is rotated by rotating the pin. The bottom of the second screw 513 extends downward through the moving platform 4. A lifting seat 514 is sleeved on the bottom surface of the second screw 513. The upper air knife assembly 511 and the lower air knife assembly 516 are respectively fixedly connected to the lifting seats 514 on both sides. The two ends of the material placement plate 515 are inserted through the second screw 513 and are located above the lifting seats 514. The adjustment components control the height difference between the upper air knife assembly 511, the lower air knife assembly 516, and the corresponding second heat separation box, which has better thermal crushing and preheating effects when dealing with plates of different thicknesses.

[0041] Adjustment plates 517 are provided on both the left and right sides inside the second mounting frame 52. A heating quartz lamp 519 is provided below the two adjustment plates 517. The heating quartz lamp 519 is located on the side of the moving platform 4 facing the honeycomb core material. A second bolt 518 is installed between the heating quartz lamp 519 and the adjustment plate 517. The moving platform 4 first passes through the heating quartz lamp 519 for heating, and then passes through the lower air knife assembly 516 and the upper air knife assembly 511 in sequence.

[0042] The preheating temperature of the heating quartz lamp 519, the hot air temperature, and the walking speed of the moving platform 4 are set by the control terminal, and the equipment preheating is started.

[0043] Automatic thermal breaking: After reaching the set temperature, the automatic operation program is started. The drive motor 41 drives the moving platform 4 and the heating unit 5 to move at a constant speed from one end of the board to the other along the slide rail. The heating quartz lamps 519 first preheat and soften the adhesive film through radiation. Then, the hot air jets from the upper air knife assembly 511 and the lower air knife assembly 516 act synchronously on the upper and lower surfaces of the board, so that the adhesive film melts and breaks evenly and is spread on the edges of the honeycomb core. Since the lower air knife assembly 516 has more and more uniformly arranged three-stage hot air pipes 59, the thermal breaking effect is mainly achieved through the lower air knife assembly 516. The function of the upper air knife is to spread the thermally broken adhesive film evenly.

[0044] The first pushing assembly 6 and the second pushing assembly 8 have the same structure, both including two symmetrically arranged synchronous belts 83. Synchronous pulleys 82 are arranged on both sides of each synchronous belt 83. A motor is installed on one side of the synchronous pulley 82 of each synchronous belt 83 for driving. Simultaneously, a synchronous roller can be installed on the synchronous pulley 82 with the motor between the two synchronous belts 83 to achieve a transmission effect by driving the two synchronous belts 83 with the motor. A structural support member 81 is arranged between the two synchronous pulleys 82. The structural support member 81 is made of industrial aluminum profile. Because the synchronous belts 83... As a flexible component, it would vibrate and deviate at high speeds. The toothed industrial aluminum profile side slots can directly lock the side limit of the timing belt 83, forcing it to maintain a straight line and preventing it from slipping or losing teeth. Simultaneously, the profile runs through the entire mechanism, providing continuous support for the long-distance timing belt 83, preventing sagging and loosening in the middle, ensuring precise meshing between the teeth and the timing pulley 82, and preventing missed steps in transmission. Both ends of the structural support component 81 are equipped with side plates 84, and the bottom of each side plate 84 is equipped with lifting rods 85 for support. Each lifting rod... Each of the lowering rods 85 has a screw jack 86 at its bottom. A second synchronous roller 87 is inserted between two screw jacks 86 on the same side. A geared motor 810 is installed between two screw jacks 86 on both sides. A third synchronous roller 89 is installed on each of the two output ends of the geared motor 810. A commutator 88 is installed at the end of each of the two third synchronous rollers 89 furthest from the geared motor 810. The commutator 88 is coaxially connected to the screw jacks 86 on both sides. A reversing structure 7 is installed on the outside of the second pushing assembly 8. The reversing structure 7 includes a section... The bottom plate 71 of the second pusher assembly 8 has multiple lifting rods 72 at its bottom. Side positioning frames 73 are provided on both the left and right sides of the bottom plate 71. A flip seat 74 for supporting the rotating shaft 22 is provided on the top of the side positioning frames 73. Spring telescopic rods 75 are provided on the side of the two side positioning frames 73 facing each other. A stop frame 76 is provided on the side of the spring telescopic rods 75 facing the bottom plate 71. Outwardly flared heads 77 are inserted into both ends of the stop frame 76. Multiple universal wheels with brakes are provided at the bottom of the lifting rods 72 and the side positioning frames 73.

[0045] Multiple screw jacks 86 are driven to rotate by a geared motor 810, a commutator 88, a second synchronous roller 87, and a third synchronous roller 89, thereby raising the top lifting rod 85. During the rising process, the top synchronous belt 83 supports the plate under it until it is freed from the support of the side crossbars 14. Then, the motor drives the plate on the first pushing assembly 6 to be transported outward to the second pushing assembly 8. During transportation, the second pushing assembly 8 can be opened simultaneously to facilitate smooth and fast movement of the plate. After being transported to the second pushing assembly 8, the geared motor 810 on the second pushing assembly 8 is opened again to lower the lifting rod 85, so that the rotating shafts 22 on both sides of the first mounting frame 2 are inserted into the flip seats 74 on the side positioning frames 73. Then, the entire second pushing assembly 8 is pushed outward in conjunction with the bottom plate 71 and the lifting rod 72 supporting it at the bottom, leaving space for the plate under. After the space is cleared, the entire board is flipped 180 degrees. Then, the second pusher assembly 8 is pushed between the two side positioning frames 73. During the movement, the baffle 76 located between the two side positioning frames 73 and the outwardly flared head 77 at the end of the baffle 76 are used to limit the entire base plate 71 and improve the feeding effect. Together with the spring telescopic rods 75 on both sides, the second pusher assembly 8 is clamped after being pushed in. The second pusher assembly 8 is opened again to push the board upward and align it with the first pusher assembly 6 raised on the front side. Then, the board is pushed onto the first pusher assembly 6 by the synchronous belt 83. Then, the first pusher assembly 6 is lowered to support the crossbars 14 on both sides of the first mounting frame 2, completing the entire flip. When the board is flipped, it needs to be left to stand for a period of time so that the top side that has been heat-broken by the adhesive film can be cooled first to prevent indentations caused by heat movement.

[0046] Finally, it should be noted that the above embodiments are merely representative examples of the present invention. Obviously, the present invention is not limited to the above embodiments and many variations are possible. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention should be considered within the protection scope of the present invention.
