DETAILED DESCRIPTION

[0023] The core of the utility model is to provide an explosion-proof plate with facing, which saves the separate construction of the external facing on site and shortens the construction period.

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0026] With reference to the drawings, Figure 1 It is the main view structure schematic diagram of the explosion-proof plate with facing of the utility model. Figure 2 It is the main view structure schematic diagram of the explosion-proof plate with facing of the utility model. Figure 3 It is the main view structure schematic diagram of the explosion-proof plate with facing of the utility model.

[0027] Embodiment 1

[0028] As Figure 1 and Figure 2As shown, the explosion-proof plate with facing includes a fiber cement core plate 1, an upper surface plate 3 and a lower surface plate 2, the fiber cement core plate 1 adopts a 8.5mm reinforced cement layer, the upper surface plate 3 and the lower surface plate 2 respectively adopt 0.5mm thick galvanized steel plates. The important difference between the explosion-proof plate with facing and the existing explosion-proof plate lies in that it further comprises a facing plate 5, and the facing plate 5 is adhered on the outer surface of the upper surface plate 3 through hot melt adhesive.

[0029] Specifically, the hot melt adhesive used here is polyurethane hot melt adhesive, which has good bonding strength and chemical corrosion resistance.

[0030] Specifically, as shown in Figure 1 and Figure 2 , the facing plate 5 specifically adopts a color coated sheet, and the color coated sheet has a thickness of 0.3-0.6mm. The color coated sheet is a material formed by coating or laminating various organic coatings or plastic films on the surface of a metal coil, which has the characteristics of good corrosion and weather resistance, and the texture and color can be selected, and the decorative property is good.

[0031] By compounding the facing plate 5 on the outer wall of the surface plate of the explosion-proof plate in the factory, the additional decoration on site is avoided, and the on-site operation cycle is shortened. By using a relatively thin color coated sheet for the facing plate 5, on-site shearing processing is facilitated, and the corrosion resistance and decorative property are good.

[0032] Example 2

[0033] During the process of bonding and compounding the facing plate 5 and the main plate of the explosion-proof plate, the facing plate 5 often occurs dislocation relative to the main plate of the explosion-proof plate during the process of pressure bonding, and the reason is that there is a lack of positioning constraint between the facing plate 5 and the upper surface plate 3. Therefore, the above-mentioned example 1 is improved to form the present example. As shown in Figure 1 and Figure 2 , a plurality of positioning pits 501 are regularly arranged on the large surface of the facing plate 5, and the positions of the positioning pits 501 coincide with the punching holes 4 formed on the upper surface plate 3. The upper surface plate 3 and the lower surface plate 2 are respectively provided with an upper spike 201 and a lower spike 301 protruding inward at the positions of the punching holes 4, and the fiber cement does not fill and flatten the punching holes 4 at the positions of the punching holes 4, i.e. square recesses are left at the positions of the punching holes 4.

[0034] Specifically, as shown in Figure 2 , the positioning pit 501 is a circular arc pit or a square notch, the area of the positioning pit 501 is smaller than that of the punching hole 4, the protruding height of the positioning pit 501 is smaller than the recess depth of the punching hole 4, and the positioning pit 501 can completely fall into the recess of the punching hole 4.

[0035] By additionally arranging the positioning pits 501 corresponding to the punching holes 4 on the veneer panel 5, when the veneer panel 5 is bonded and combined, the positioning pits 501 enter the pits of the punching holes 4 to be positioned, so that the veneer panel 5 and the punching holes 4 are prevented from being dislocated during the pressing process; meanwhile, the positioning pits 501 can extrude the hot melt adhesive stored in the pits of the punching holes 4, so that the waste of the hot melt adhesive is avoided, the bonding area is increased, the bonding strength is improved, and the risk of the veneer panel 5 falling off is reduced.

[0036] It needs to be explained that, although the additional positioning pits 501 cause the outer wall of the veneer panel 5 not to be a flat plane, this does not affect the appearance, and on the contrary, the three-dimensional sense in the decoration is increased, and the positioning pits 501 itself is a kind of decorative pattern.

[0037] Embodiment 3

[0038] The utility model discloses still disclose a kind of veneer roll mechanism, for processing the veneer panel 5 in above-mentioned embodiment 2, including frame 6, convex roll 7 and concave roll 8, frame 6 rotationally supports convex roll 7 and concave roll 8, convex roll 7 and concave roll 8 are arranged horizontally upside down and are counter-rotated. Convex roll 7 is driving roll and is provided with coaxially connected speed reducer 12 at one end thereof, the main shaft of convex roll 7 and concave roll 8 is connected by gear meshing of counter-opening on the other end, to ensure that convex roll 7 and concave roll 8 counter-synchronous rotation. It is obvious that, convex roll 7 and concave roll 8 can also be driven independently by speed reducer 12 respectively, and linkage operation is carried out on electricity, to ensure counter-synchronous rotation. The continuous veneer veneer panel 5 to be processed passes between the roll gap of convex roll 7 and concave roll 8. Convex roll 7 outer wall is provided with regularly arranged convex block, and concave roll 8 outer wall is provided with corresponding pit. Veneer panel 5 is processed into downward convex positioning pit 501 after passing between the roll gap of convex roll 7 and concave roll 8.

[0039] Specifically, frame 6 is installed above the front end of veneer panel 5 bonding and combining station, and positioning pit 501 is processed online before combining.

[0040] By adopting the roll-pressing type processing of the continuous veneer veneer panel 5 by convex roll 7 and concave roll 8, downward convex positioning pit 501 can be continuously and quickly processed on veneer panel 5. By reasonably arranging frame 6 to be installed above the front end of veneer panel 5 combining station, online processing of positioning pit 501 can be achieved, and the work efficiency is improved.

[0041] In a specific embodiment of the utility model, as shown in Figure 3 The main shaft of concave roll 8 is rotationally supported by bearing seat 9 after passing through the through hole of the vertical wall of frame 6. The through hole has a large adjustment amount in the vertical direction, i.e. the main shaft of concave roll 8 can move slightly up and down. Vertically shaped holes 901 are formed on both sides of bearing seat 9, and locking screws 10 are connected to the threaded holes of frame 6 after passing through the vertically shaped holes 901.

[0042] Specifically, asFigure 3 As shown, the upper welding of the stand wall 6 is provided with a top screw hole block 601, which is directly below the bearing seat 9. The top screw hole block 601 is threadedly connected with a top screw 11, and the top end of the top screw 11 abuts against the middle position of the bottom surface of the bearing seat 9.

[0043] By arranging the vertical waist-shaped holes 901 on both sides of the bearing seat 9, the height position of the concave roller 8 can be slightly adjusted, so as to facilitate debugging and adaptation to different thicknesses of the veneer panel 5. By arranging the top screw hole block 601 and the top screw 11, the upward adjustment of the concave roller 8 can be facilitated.

[0044] The working process of the veneer panel roller pressing mechanism is as follows: the unwinding device continuously unwinds the veneer panel 5, and the speed reducer 12 drives the convex roller 7 and the concave roller 8 to synchronously rotate in opposite directions. The veneer panel 5 to be processed enters the roller gap from the feeding side of the convex roller 7 and the concave roller 8. When passing through the roller gap, the convex roller 7 and the concave roller 8 not only press the veneer panel 5 on the large surface, but also locally press the veneer panel 5 downward by the convex blocks on the convex roller 7, so that the veneer panel 5 is locally deformed downward and protrudes into the concave pits of the concave roller 8. Therefore, the veneer panel 5 is processed with all the positioning pits 501 on the large surface after passing through the convex roller 7 and the concave roller 8. The processed veneer panel 5 enters the composite station for pressure bonding.

[0045] In summary, the veneer panel roller pressing mechanism can continuously and quickly process the downward protruding positioning pits 501 on the veneer panel 5 by adopting the roller pressing type processing of the veneer panel 5 in combination with the convex roller 7 and the concave roller 8. By reasonably arranging the rack 6 to be installed above the front end of the veneer panel 5 composite station, the positioning pits 501 can be processed online, and the working efficiency is improved. By arranging the vertical waist-shaped holes 901 on both sides of the bearing seat 9, the height position of the concave roller 8 can be slightly adjusted, so as to facilitate debugging and adaptation to different thicknesses of the veneer panel 5. By arranging the top screw hole block 601 and the top screw 11, the upward adjustment of the concave roller 8 can be facilitated.

[0046] The various embodiments in the specification are described in a progressive manner, and each embodiment focuses on the difference from other embodiments. The same or similar parts of each embodiment can be referred to each other. For the device disclosed in the embodiments, since it corresponds to the method disclosed in the embodiments, the description is relatively simple, and the related parts can be referred to the method part.
