[0001] The present invention relates to the technical field of plate pressing, and particularly relates to a pressing device for producing heat preservation boards. Background Art

[0002] A heat preservation board is a common building material, mainly made of materials such as polystyrene and rock wool, and has good heat insulation and heat preservation properties. It is widely used in parts such as the exterior walls and roofs of buildings, and can effectively improve the energy use efficiency of buildings. In order to make the heat preservation board take into account heat preservation performance, aesthetics and structural strength, the heat preservation board usually consists of multiple layers of plates, such as two plates, one heat preservation layer, and one strengthening layer, and the two are usually bonded to each other by a colloid to ensure the stability of the heat preservation board during subsequent use. In this way, a pressing device is required to press the two plates together. Most of the existing pressing devices only apply a vertically downward force to the two plates, so that the colloid between the plates is subjected to a single force and is difficult to be evenly distributed on the plates, resulting in the problem of uneven distribution of the colloid between the plates. Therefore, this application proposes a pressing device for producing heat preservation boards to solve the above problems. Summary of the Invention

Detailed implementation manners

[0023] The present invention will be further described in detail below in conjunction with the attached drawings and specific implementation manners. The embodiments of the present invention are given for the purpose of illustration and description, and are not exhaustive or limit the present invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and enable those of ordinary skill in the art to understand the present invention and thus design various embodiments with various modifications suitable for specific purposes.

[0024] As Figures 1-4 shown, a pressing device for producing heat-insulating boards according to an embodiment of the present invention is proposed to solve the problem that when the existing pressing device works, it can only press the board material "vertically up and down", resulting in more force on the colloid between the board materials than single, making it difficult to be evenly distributed on the board material, and there is a problem of uneven distribution of the colloid between the board materials. It includes: a frame body 1, the frame body 1 is provided with a groove for limiting the board material 101; guide posts 2, the number of which is more than two, are all fixedly connected to the frame body 1, the guide posts 2 are slidably connected with limit rings 3, and a plurality of limit rings 3 are jointly slidably connected with a moving plate 4; guide rods 5, which are arranged at intervals, are all slidably connected to the moving plate 4, and a plurality of guide rods 5 are jointly fixedly connected with an extrusion plate 601, the extrusion plate 601 is used for extruding the board material 101, and a first elastic element 602 is fixedly connected between the moving plate 4 and the extrusion plate 601; a power mechanism, which is arranged on the frame body 1 and is used for making the guide posts 2 and the moving plate 4 slide relatively; a limiting mechanism, which is arranged on the moving plate 4 and is used for making the adjacent board materials 101 slide relatively, so as to evenly disperse the colloid between the adjacent board materials 101.

[0025] In the above solution, there are four uniformly arranged guide posts 2, which are used to limit the position of the limit ring 3. The moving plate 4 is used to limit the position of the guide rod 5. A rubber pad is provided on the lower side of the pressing plate 601 for relative fixation with the upper plate 101. The first elastic element 602 is a spring, which is used to apply pressure to the pressing plate 601. During the production of the insulation board, the plate 101 is placed on the groove on the frame 1 (the upper side of the plate 101 has been coated with glue), and then another plate 101 is placed on the previous plate 101. Subsequently, the moving plate 4 is moved downward by the power mechanism. The guide rod 5 and the pressing plate 601 move downward together with the moving plate 4 under the action of their own gravity. After the pressing plate 601 moves downward to contact the (upper) plate 101, as the moving plate 4 continues to move downward, since the (upper) plate 101 blocks the pressing plate 601 at this time, that is, the moving plate 4 slides downward along the guide rod 5, and the first elastic element 602 is compressed. The elastic force generated by the deformation of the first elastic element 602 is applied to the (upper) plate 101 through the pressing plate 601, so that the two plates 101 are closely attached. During the downward movement of the moving plate 4, the limiting mechanism is used to make the moving plate 4 move on the horizontal plane. The moving plate 4 drives the pressing plate 601 to move together through the guide rod 5, so that the upper plate 101 moves horizontally on the lower plate 101, thereby making the glue between the two plates 101 be pressed and evenly dispersed, so as to improve the uniformity of the glue between the two plates 101 and improve the pressing effect of the plate 101.

[0026] During the compression of the first elastic element 602, the first elastic element 602 gradually transfers the force to the pressing plate 601, so that the force applied by the pressing plate 601 to the upper plate 101 is in a gradual change, so as to prevent the force instantaneously applied to the upper plate 101 from causing the glue to "overflow excessively", so that the glue is extruded before it has time to be evenly contacted with the two plates 101, resulting in the glue being difficult to completely fill between the two plates 101, thereby reducing the pressing quality of the two plates 101.

[0027] As Figures 2-4 shown, the power mechanism includes: a hydraulic push rod 701, which is installed on the frame 1. The telescopic end of the hydraulic push rod 701 is fixedly connected with a pressing member 702. The pressing member 702 is slidably connected with the moving plate 4. A second elastic element 703 is arranged between the pressing member 702 and the moving plate 4; the limiting mechanism includes: a plurality of first limiting rods 801, which are arranged at intervals and are all fixedly connected to the moving plate 4. The frame 1 is provided with limiting grooves 802 arranged at intervals, and the limiting grooves 802 are used to limit the first limiting rods 801. The limiting grooves 802 are composed of a vertical groove and a wavy groove, and the projection of the limiting grooves 802 on the horizontal plane is arc-shaped. A third elastic element 803 is arranged between the limit ring 3 and the moving plate 4.

[0028] In the above solution, both the second elastic element 703 and the third elastic element 803 are rubber rings, which are used to reset the moving plate 4 and reduce the vibration when the moving plate 4 slides relative to the limiting ring 3. The moving plate 4 limits the extrusion part 702 in the up and down directions. The first limiting rods 801 are evenly arranged on the moving plate 4 to evenly distribute the force on the moving plate 4. The limiting groove 802 is vertically arranged as a whole. There are two vertical grooves and a wavy groove between them on the limiting groove 802. The axes of the two vertical grooves coincide. The wavy groove on the limiting groove 802 is inclined (taking Figure 3 the top view direction as an example, there is an included angle between the wavy groove on the limiting groove 802 and the "X" axis), which is used to make the moving plate 4 slide relative to the limiting ring 3. The telescopic end of the hydraulic push rod 701 drives the extrusion part 702 to move downward. The extrusion part 702 drives the moving plate 4 to move downward together. The moving plate 4 drives the limiting ring 3 and the first limiting rods 801 to move downward together. The limiting ring 3 starts to slide downward along the guiding column 2. The first limiting rods 801 start to slide in the upper vertical groove of the limiting groove 802. After the first limiting rods 801 move downward to enter the wavy groove on the limiting groove 802, under the limiting action of the wavy groove on the limiting groove 802, the first limiting rods 801 start to move horizontally relative to the extrusion part 702. The first limiting rods 801 drive the moving plate 4 to move horizontally together. The limiting ring 3 and the extrusion part 702 both slide relative to the moving plate 4. The second elastic element 703 and the third elastic element 803 are both compressed. During the process, the moving plate 4 drives the extrusion plate 601 to move horizontally together through the guiding rod 5, so as to make the two plates 101 perform a "comprehensive" relative movement in the horizontal direction, thereby improving the uniformity of the pressure during the pressing process of the plates 101, and at the same time reducing problems such as deformation and dislocation of the plates 101, and ensuring the production quality of the insulation board.

[0029] As Figures 5-7 shown, it further includes: a second limiting rod 901, which is a plurality of spaced-apart ones, and is fixedly connected to the extrusion part 702. The second limiting rod 901 is provided with a first limiting column. The frame 1 is fixedly connected with a plurality of spaced-apart guiding members 902. The guiding members 902 are slidably connected to the adjacent second limiting rods 901. The frame 1 is slidably connected with a plurality of spaced-apart first sliding members 903. The first sliding members 903 are provided with a first inclined surface 904. The limiting columns on the second limiting rods 901 are used to extrude the first inclined surface 904. A fourth elastic element 905 is fixedly connected between the first sliding members 903 and the frame 1; a first leveling member 906, which is a plurality of spaced-apart ones, and is respectively fixedly connected to the adjacent first sliding members 903. The opposite sides of the plurality of first leveling members 906 are all provided with a first arc surface 907, which is used to extrude the overflowing material on the plate 101.

[0030] In the above solution, there are four second limiting rods 901, guiding members 902, first sliding members 903 and first leveling members 906 arranged circumferentially. The guiding members 902 are used to limit and guide the adjacent second limiting rods 901, corresponding to the four edges of the plate 101 respectively. The distance between the four first inclined surfaces 904 gradually increases from top to bottom, and is used to make the first sliding members 903 move towards each other when being extruded by the second limiting rods 901. The fourth elastic element 905 is a spring and is used to reset the adjacent first sliding members 903. The center of the first arc surface 907 is aligned with the joint between the two plates 101. The distance between the two opposite first arc surfaces 907 first increases and then decreases from top to bottom, and is used to extrude the colloid overflowing between the two plates 101 to different degrees. During the downward movement of the extruding member 702, the extruding member 702 drives the second limiting rod 901 to move downward together. The second limiting rod 901 slides relative to the adjacent guiding member 902. After the first limiting column on the second limiting rod 901 moves downward to contact the first inclined surface 904, the first limiting column on the second limiting rod 901 begins to extrude the first inclined surface 904. Subsequently, the four first sliding members 903 begin to move towards each other. The first sliding members 903 slide relative to the frame body 1. The fourth elastic element 905 is compressed. The first sliding members 903 drive the first leveling members 906 to move together. The first leveling members 906 gradually contact the colloid overflowing between the two plates 101 due to pressing, and extrude the colloid to the upper and lower sides of the gap between the two plates 101, so that the overflowing colloid is in full contact with the plates 101, thereby ensuring the adhesion between the two plates 101 after pressing, improving the pressing quality of the insulation board, and using the first arc surface 907 to extrude the colloid overflowing between the two plates 101 to different degrees, and extruding the overflowing colloid into a strip shape with an "arc" area in the cross section, so that the amount of colloid accumulated in the gap between the two plates 101 is relatively large, thereby increasing the shear resistance of the bonding area of the insulation board, and further improving the pressing quality of the insulation board.

[0031] Such as Figure 5 and Figure 7As shown in the figure, it further includes: a plurality of third limiting rods 1001 arranged at intervals, which are respectively fixedly connected to adjacent second limiting rods 901. The third limiting rods 1001 are provided with second limiting columns. The frame 1 is slidably connected with second sliding members 1002 arranged at intervals. The second sliding members 1002 are provided with second inclined surfaces 1003. The second limiting columns on the third limiting rods 1001 are used to squeeze the second inclined surfaces 1003. A fifth elastic element 1004 is fixedly connected between the second sliding members 1002 and the frame 1. The second sliding members 1002 are fixedly connected with second leveling members 1005. The second leveling members 1005 are used to contact adjacent first leveling members 906. The second leveling members 1005 are provided with second arc surfaces 1006. The diameter of the second arc surface 1006 is larger than that of the first arc surface 907, which is used to focus on processing a local area of the plate 101. The distance between the second arc surface 1006 and the plate 101 is greater than the distance between the first arc surface 907 and the plate 101.

[0032] In the above solution, both the third limiting rods 1001 and the second sliding members 1002 are four arranged circumferentially, corresponding to the four corners of the plate 101 respectively. The distance between the four second inclined surfaces 1003 gradually increases from top to bottom. The fifth elastic element 1004 is a spring, which is used to reset the adjacent second sliding members 1002. The first leveling member 906 and the adjacent second leveling member 1005 are in a state of mutual contact during the working process. The inner diameter of the second arc surface 1006 gradually increases from outside to inside. The area with the smallest inner diameter on the second arc surface 1006 is used to contact (seam) the adjacent first arc surface 907, so that the overflowing colloid is gently arranged in the four corner areas on the outer side of the plate 101 (that is, the overflowing colloid is gently connected between the flat area and the four corner areas on the outer side of the plate 101), so as to improve the ability of the pressed insulation board to bear local stress during subsequent use. During the downward movement of the second limiting rod 901, the limiting rod 901 drives the adjacent third limiting rod 1001 to move downward together. After the second limiting column on the third limiting rod 1001 moves downward to contact the second inclined surface 1003, the second limiting column on the third limiting rod 1001 begins to squeeze the second inclined surface 1003. Subsequently, the four second sliding members 1002 start to move towards each other. The second sliding members 1002 slide relative to the frame 1. The fifth elastic element 1004 is compressed. The second sliding members 1002 drive the second leveling members 1005 to move together. The second leveling members 1005 gradually contact the colloid overflowing due to pressing between the two plates 101, and squeeze the colloid to the upper and lower sides of the gap between the two plates 101, so that the colloid is evenly distributed at the four corners of the plate 101, thereby reducing the cracking probability at the four corners of the insulation board. And by using the gentle "seam" between the second arc surface 1006 and the adjacent first arc surface 907, the overflowing colloid is gently arranged on the outer side of the plate 101, thereby improving the pressing quality of the insulation board.
