Example 1:
as shown in fig. 1, the present embodiment provides a material composite processing apparatus, including: the first-stage composite mechanism and the second-stage composite mechanism are sequentially arranged along the material conveying direction, and are used for compounding the first surface layer with the upper surface of the core layer, and the second-stage composite mechanism is used for compounding the second surface layer with the lower surface of the core layer; that is to say, the second-level composite mechanism is located at the downstream of the first-level composite mechanism, and the upper surface of the core layer is subjected to the composite process with the first surface layer and then enters the second-level composite mechanism to be subjected to the composite process with the second surface layer.
In detail, the primary composite mechanism comprises a core layer preheating assembly, a first preheating assembly and a first heating assembly, wherein the core layer preheating assembly is suitable for preheating the upper surface and the lower surface of the core layer, the first preheating assembly is suitable for preheating the first surface layer, and the first heating assembly is suitable for heating the first surface layer and the upper surface of the core layer; and the secondary composite mechanism comprises a second preheating assembly suitable for preheating the second surface layer and a second heating assembly suitable for heating the second surface layer and the lower surface of the core layer.
It should be noted that, for the first heating assembly of this embodiment, the main function is to perform instantaneous heating on the joint surface of the first surface layer and the upper surface of the core layer, so that the joint surfaces of the first surface layer and the core layer generate an instantaneous melting effect, a liquid medium needs to be introduced into the first preheating roller to perform roller surface temperature control, such as heat conduction oil, or an electromagnetic heating roller is directly used, that is, the instantaneous melting effect is only generated on the joint surface, and no such effect is generated for other parts, so that the flatness of the composite rear surface is improved during the composite processing between the first surface layer and the upper surface of the core layer.
The core layer preheating assembly comprises an upper annular preheating structure and a lower annular preheating structure, wherein the upper annular preheating structure is suitable for preheating the upper surface of the core layer, and the lower annular preheating structure is suitable for preheating the lower surface of the core layer; here the upper annular pre-heating structure is located above the core layer and the lower annular pre-heating structure is located below the core layer. Specifically, taking an optional implementation case as an example, the upper annular preheating structure comprises a pair of upper transmission rollers 1 and an upper annular preheating belt 2 which is arranged between the pair of upper transmission rollers 1 and is suitable for being driven by the pair of upper transmission rollers 1 to operate; the lower annular preheating structure comprises a pair of lower driving rollers 5 and a lower annular preheating belt 3 which is arranged between the pair of lower driving rollers 5 and driven by the pair of lower driving rollers 5 to rotate, the operation directions of the upper annular preheating belt 2 and the lower annular preheating belt 3 are opposite, namely, the upper annular preheating belt 2 and the lower annular preheating belt 3 preheat the upper surface and the lower surface of the core layer, and meanwhile, the conveying power for the core layer is formed jointly through the incongruous operation of the upper annular preheating belt 2 and the lower annular preheating belt 3. For the upper and lower endless preheating belts 2, 3 of the present embodiment, for example, but not limited to, teflon endless belts may be used alternatively.
It should be further noted that, in this embodiment, the distance between the lower driving roller 5 adjacent to the secondary composite mechanism in the pair of lower driving rollers 5 and the secondary composite mechanism is smaller than the distance between the upper driving roller 1 adjacent to the secondary composite mechanism in the pair of upper driving rollers 1 and the secondary composite mechanism, so that the significance of the design lies in that on one hand, after the preheating of the core layer is completed, the core layer can be conveyed to the position of composite processing through the lower annular preheating belt 3, on the other hand, the preheated core layer can be prevented from softening and sagging, and the core layer can play a role in supporting the core layer softened after heating, and is particularly suitable for the composite processing of discontinuous core materials and surface layers.
With reference to the attached drawings of the present embodiment, taking an optional implementation case as an example, the upper transmission roller 1 far away from the secondary compound mechanism in the pair of upper transmission rollers 1 is located right below the lower transmission roller 5 far away from the secondary compound mechanism in the pair of lower transmission rollers 5; and the distance between the lower transmission roller 5 adjacent to the second-stage composite mechanism in the pair of lower transmission rollers 5 and the second-stage composite mechanism is smaller than the distance between the upper transmission roller 1 adjacent to the second-stage composite mechanism in the pair of upper transmission rollers 1 and the second-stage composite mechanism, so that the preheated core layer can be conveyed to a composite processing position through the lower annular preheating belt 3 after being preheated, the preheated core layer can be prevented from softening and sagging, and the effect of supporting the heated softened core layer is achieved.
It should be further noted that, in the core preheating unit, an upper heating structure adapted to heat the upper endless preheating zone 2 is provided inside the upper endless preheating zone 2, and a lower heating structure adapted to heat the lower endless preheating zone 3 is provided inside the lower endless preheating zone 3. The upper heating structure and the lower heating structure can be heated by adopting a flat plate type heating plate 6 or heated by infrared rays or an oven, the heating temperature can be measured and also regulated, the temperature can be controlled, the heat is transferred to the upper annular preheating zone 2 and the lower annular preheating zone 3, then the heat is transferred to the upper surface and the lower surface of the core layer respectively through the upper annular preheating zone 2 and the lower annular preheating zone 3, the annular preheating zone is driven by a driving roller to continuously rotate, and the core layer is conveyed between the upper annular preheating zone 2 and the lower annular preheating zone 3 and is subjected to surface heating. It should be noted here that the key to the preheating process of the core material by the upper heating structure and the lower heating structure is that the surface layer of the thermoplastic core material is heated at a temperature lower than the melting point of the thermoplastic material and close to the melting point, so that the surface of the core material is maximally preheated but less than the melting point of the thermoplastic material.
The first preheating assembly comprises a pair of first preheating rollers arranged in parallel, namely the pair of first preheating rollers are in a parallel distribution state, and it should be noted that the two first preheating rollers arranged in parallel are not limited to be arranged in parallel relative to a horizontal line, but only the contact surfaces of the two first preheating rollers and the first surface layer are in a parallel distribution structure, so that the first surface layer can pass through the two first preheating rollers arranged in parallel in an S-shaped track. The first preheating roller far away from the upper annular preheating belt 2 in the pair of first preheating rollers is mainly used for preheating the surface of the first surface layer attached to the first preheating roller, the actual temperature of the attaching surface of the surface layer material of the first preheating roller is smaller than the melting point of the first surface layer material, the effect of fully preheating the surface of the first surface layer attached to the first preheating roller is achieved, and the temperature of the first preheating roller can be independently adjusted.
The first heating assembly includes a first core surface heating structure 11 located between the first preheating assembly and the upper annular preheating structure and adapted to heat the upper surface of the core, and a first arc-shaped heating structure 12 provided around the outer surface of the first preheating roller of the pair of first preheating rollers adjacent to the upper annular preheating structure, where the first arc-shaped heating structure 12 may be about 1/2 length portions corresponding to the circumferential direction of the first preheating roller (it should be noted that this 1/2 length portion is not absolute, and may be set as 1/2 length portions, or other portions, this embodiment is merely an example, and in particular, the cladding heating angle may be flexibly adjusted according to the requirements of different specific facing materials). For the first arc-shaped heating structure 12 of the present embodiment, the first arc-shaped heating structure 12 herein performs the function of instantaneously heating the faying surface of the facing layer so as to melt the faying surface of the material facing layer.
Optionally, in an instant melting mode of the first core layer surface heating structure 11 on the upper surface of the core layer, the core layer is heated by infrared rays, the core layer is preheated sufficiently by the core layer preheating assembly, and then the upper surface of the core layer is separated from the upper annular preheating structure and enters the infrared ray instant melting heating area corresponding to the first core layer surface heating structure 11, so that the first core layer surface heating structure 11 produces an instant melting effect on the upper surface of the core layer, because the surface temperature of the core layer is higher than the temperature below the surface of the core layer when the surface of the core layer is heated by infrared rays, the surface of the core layer can firstly reach the melting point of the material to generate the melting effect when the surface of the core layer is heated by infrared rays, but the part below the surface of the core layer cannot generate melting effect because the rising speed of the temperature lags behind the surface of the core layer, and a relatively complete mechanical structure of the core layer material in a heated state is ensured. The infrared heating power for the first core surface heating structure 11 is linearly adjustable.
The first arc-shaped heating structure 12 can select an infrared heating mode, the infrared heating power can be linearly adjusted, the first surface layer enters the first preheating roller (defined as the second preheating roller 9 in the embodiment) adjacent to the upper annular preheating zone 2 in the pair of first preheating rollers after being preheated by the first preheating roller (defined as the first preheating roller 7 in the embodiment) far away from the upper annular preheating zone 2 in the pair of first preheating rollers, and the roller surface temperatures of the first preheating roller 7 and the second preheating roller 9 can be independently adjusted. Because the first surface layer passes through the two first preheating rollers which are installed in a staggered mode in an S-shaped track, the wrapping surface of the first surface layer on the first preheating roller 7 is the air contact surface (the reverse side of the wrapping surface) of the first surface layer on the second preheating roller 9, the surface is instantly melted after being instantly heated and baked by infrared rays, but the heating temperature of the second preheating roller 9 is lower than the melting point of the material and can be adjusted, so that the wrapping surface of the material and the second preheating roller 9 and the part below the surface layer are not melted, the strength of a part is ensured, and the effect of instant melting is only generated on the surface part of the air contact surface. What that say that what play to preheating roll 7 of this embodiment is actually the effect of preheating to first surface course laminating face, also can make first surface course can be in the in-process that heats by arc heating structure after preheating simultaneously can laminate on preheating roll 9 No. flatly, thereby several points are in sum improved the roughness of the laminating surface that the upper surface of holistic first surface course and sandwich layer formed in one-level combined machining process.
Taking an alternative case as an example, the first preheating roller (defined as second preheating roller 9 in the present embodiment) adjacent to the upper annular preheating structure in the pair of first preheating rollers is positioned directly above the lower driving roller 5 adjacent to the secondary compounding mechanism in the lower annular preheating structure, so that the second preheating roller 9 and the lower driving roller 5 adjacent to the secondary compounding mechanism in the lower annular preheating structure together form a compound processing for the first surface layer and the upper surface of the core layer. That is to say, for the first-order composite mechanism of this embodiment, the combined machining between the upper surface of the core layer and the first surface layer is directly realized through the second preheating roller 9 and the lower driving roller 5, the composite pressure below the core layer acts on the core layer through the lower driving roller 5, the first hot-pressing compounding is performed between the core layer passing through the first core layer surface heating structure 11 and the first surface layer passing through the first arc-shaped heating structure 12 in the pair of first preheating rollers, the first preheating roller adjacent to the upper annular preheating structure, and the lower driving roller 5 adjacent to the second-order composite mechanism in the lower annular preheating structure, and the two molten surfaces are closely attached together after the first hot-pressing compounding. Because the parts of the first surface layer and the core layer except the jointed surface are not melted, but the jointed surface is instantaneously melted, the surface is a smooth surface without concave-convex after the first surface layer and the core layer are compounded.
Because the lower driving roll 5 of the adjacent second-level composite mechanism in the lower annular preheating structure plays a role of a lower composite roll in the first hot-pressing composite process, under the structure, the lower annular preheating zone 3 plays a role in supporting the core layer in the first hot-pressing composite processing process, so that the discontinuous core layer cannot sag even after being preheated and softened, and the softened sagging can cause that the discontinuous core layer cannot enter the composite roll to be compounded.
The second preheating assembly includes a pair of second preheating rollers 10 arranged in parallel. The second heating assembly comprises a second core surface heating structure 18 located between the second preheating assembly and the lower annular preheating structure and adapted to heat the lower surface of the core, and a second arcuate heating structure 19 provided around the outer surface of the second preheating roll 10 of the pair of second preheating rolls 10 adjacent to the lower annular preheating structure, where the second arcuate heating structure 19 acts to momentarily heat the core such that the material web melts. For the specific implementation principle of the second preheating assembly of this embodiment, reference may be made to the first preheating assembly, and details thereof are not repeated here. It should be noted that, the second core layer surface heating structure 18 of this embodiment is disposed at a position between the lower driving roller 5 and the second arc-shaped heating structure 19, so that the whole apparatus is more compact to receive the lower surface of the core layer preheated by the lower annular preheating structure, and the lower surface of the core layer is subjected to instantaneous heating operation to achieve the effect of instantaneous melting of the lower surface of the core layer and the bonding surface of the second surface layer.
The secondary composite structure further comprises a composite roll 17 arranged right above the second preheating roll 10 adjacent to the lower annular preheating structure in the pair of second preheating rolls 10, so that the composite roll 17 and the second preheating roll 10 adjacent to the lower annular preheating structure in the pair of second preheating rolls 10 jointly form a composite processing for the lower surfaces of the second surface layer and the core layer.
For example, in an optional case, the primary composite mechanism further includes a first unwinding structure 15 adapted to be directly connected to a first preheating roller of the pair of first preheating rollers, which is far from the upper annular preheating structure, and adapted to unwind the first surface layer. The secondary composite structure further comprises a second unwinding structure 16 adapted to unwind the second facing layer, and adapted to be in direct contact with a second preheating roller 10 of the pair of second preheating rollers 10 remote from the lower endless preheating structure. The effect that unreels in succession that first surface course and second surface course realized through first structure 15 and the second structure 16 of unreeling unreel for after the one-level is compound, by the continuous traction of first surface course, make the sandwich layer behind the compound first surface course can be thereupon smooth get into the compound station of second grade combined mechanism, can solve the no trace compound difficult point of intermittent sandwich layer like this.
Considering that the two compounding processes used between the core layer and the first and second facing layers may have a certain stress to the composite product after the second-stage compounding, which may cause warping, the stress relief mechanism 13 is configured in the downstream process after the second-stage compounding, such as but not limited to a heating oven part, which may be flexibly processed, a hot air oven, an infrared heating oven, an electric heating oven, or a plate heating. And (3) carrying out secondary heating softening on the compounded finished product through the stress relieving mechanism 13 to relieve stress, cooling the compounded finished product out of the stress relieving mechanism 13 in a flat state, carrying out roller cooling or plate cooling, and finally cutting to obtain a flat finished product plate.
The core layer suitable for the material composite processing equipment of the embodiment may be a core material having a certain structural strength, or may be a flexible core material, and may be intermittently compounded. The special hot melt adhesive film is needed for compounding part of the special surface layer material and the core layer, the hot melt adhesive film can be simultaneously unreeled together with the unreeling surface layer, and the unreeled surface layer and the unreeling surface layer are combined and stacked and then enter the two preheating roller stations together to be laminated in the compounding station, so that multifunctional compounding is realized.
Example 2:
as shown in fig. 2, the composite material processing apparatus provided in this embodiment has the same general structure as the composite material processing apparatus of embodiment 1, except that the composite material processing apparatus further includes a pressing roller 20 additionally disposed between the pair of lower driving rollers 5 of the lower annular preheating structure, and the pressing roller 20 is located right below the second preheating roller 9.
It should be further noted that, regarding the length of the lower annular preheating zone 3 in this embodiment, the lower annular preheating zone 3 in this embodiment extends to the downstream of the primary composite mechanism, since the primary composite mechanism implements the composition between the upper surface of the core layer and the first surface layer, and the secondary composite mechanism only starts to perform the composite processing on the lower surface of the core layer and the second surface layer, in order to effectively ensure the preheating temperature of the lower surface of the core layer in the secondary composite processing process, the length of the lower annular preheating zone 3 designed in this embodiment needs to be in direct contact with the secondary composite mechanism. Under such a structure, under an optional condition, because lower annular preheating zone 3 extends to the low reaches department of one-level combined mechanism, for preventing the lower surface of the sandwich layer after lower annular preheating zone 3 preheats to bond on lower annular preheating zone 3 and the adhesion phenomenon appears when breaking away from lower annular preheating zone 3, can increase a temperature control board 22 in lower annular preheating zone 3 part after the one-level is compound, adjust the temperature of lower annular preheating zone 3 through temperature control board 22 so that the lower surface of sandwich layer can keep effectual preheating effect and be unlikely to the adhesion phenomenon again, also can play the effect of carrying out the secondary heating to the sandwich layer lower surface that the temperature is not in place under some circumstances.
