Description

Technical Field

[0001] This utility model belongs to the field of pressing equipment technology, specifically relating to a pressing equipment for thermal insulation materials. Background Technology

[0002] Thermal insulation decorative panels, also known as integrated thermal insulation decorative panels, are composed of insulation materials and decorative panels, primarily used for exterior wall insulation. During production, these panels are pressed together using a pressing device. Single-layer insulation materials have limited practicality, failing to meet requirements in terms of strength and insulation performance. Pressing multiple layers of insulation materials significantly improves the insulation effect. In the production of integrated thermal insulation decorative panels composed of polystyrene or XPS insulation core material and metal or PVC decorative panels, multiple layers of PVC-reinforced insulation material require a pressing process to enhance structural strength and insulation performance.

[0003] In the existing pressing process, if the insulation material is not placed in the pressing zone according to its position, the insulation material will deform and the pressing will be uneven, resulting in air bubbles inside the multi-layer insulation material, which will greatly reduce the insulation effect. Utility Model Content

[0004] This utility model provides a thermal insulation material pressing device, which aims to solve the problem that if the thermal insulation material is not placed in the pressing zone according to the position during the pressing process, the thermal insulation material will deform, the pressing will be uneven, and air bubbles will be present inside the multi-layer thermal insulation material, thus greatly reducing the thermal insulation effect.

[0005] This utility model provides a thermal insulation material pressing device, including a pressing table. Support columns are fixed at the four corners of the upper surface of the pressing table, and a top plate is fixed at the top of the support columns. A hydraulic cylinder is installed on the lower side of the top plate, and a pressing plate is installed at the output end of the hydraulic cylinder. A pressing zone is provided in the middle of the pressing table, and a correction mechanism is provided inside the pressing table directly below the pressing zone.

[0006] Furthermore, the upper surface of the pressing table is provided with a slide that connects to its interior, and the slide extends towards the center of the pressing table to the edge of the pressing area.

[0007] By adopting the above technical solution, the slide is a set of four radially opened straight guide grooves, the width of which is matched with the clearance of the correction mechanism, so that the correction mechanism does not shake when moving horizontally. When the insulation board is misplaced, the correction mechanism can extend precisely along the slide to the surface of the pressing table and forcefully push the insulation board to the correct position, avoiding uneven heat melt flow during pressing due to misalignment of the PVC decorative layer.

[0008] Furthermore, the correction mechanism includes a fixed base, a fixed rod fixed in the middle of the fixed base, the fixed rod being fixed to the top of the inner wall of the pressing table, a movable base at the bottom of the fixed base, the fixed base and the movable base being connected by an electric push rod, an upwardly extending L-shaped limiting plate integrally formed on the periphery of the movable base, and a first movable groove in the middle of the upward-facing end of the limiting plate.

[0009] By adopting the above technical solution, the electric push rod can drive the movable seat to move up or down when it retracts or pushes outward. The purely mechanical transmission ratio reaches 1:2.5, ensuring a rapid response to the offset PVC insulation board.

[0010] Furthermore, a protruding strip is fixed on the upper surface of the fixed base, a slider slides on the protruding strip, an L-shaped drive plate is fixed on the slider, the drive plate is arranged opposite to the limiting plate, a second movable groove is provided in the middle of the downward-facing end of the drive plate, an extension plate is fixed on the upper surface of the drive plate, and a correction plate extends upward from the end of the extension plate away from the fixed rod.

[0011] By adopting the above technical solution, the drive plate and extension plate adopt an integrated L-shaped structure. The drive plate forms a sliding pair with a slider and a convex strip, and a correction plate extends upward from the other end of the drive plate. When the drive plate moves horizontally under the action of the slider, the extension plate transmits force to the correction plate, causing it to move radially synchronously within the slide. A polyurethane buffer layer is attached to the working surface of the correction plate to prevent scratches on the surface when pushing the PVC panel.

[0012] Furthermore, a connecting plate is movably connected between the first movable slot and the second movable slot.

[0013] By adopting the above technical solution, the two ends of the connecting plate are respectively hinged to the first movable groove and the second movable groove by pins. When the limiting plate moves vertically with the movable seat, the tilt angle of the connecting plate changes. Through the hinge action between the first movable groove and the connecting plate and the other end of the connecting plate and the second movable groove, the vertical movement of the movable seat is converted into the horizontal movement of the slider, thereby causing the drive plate to slide radially along the convex strip.

[0014] Furthermore, the correction plate extends through the slide to the upper surface of the pressing table.

[0015] By adopting the above technical solution, the bottom of the correction plate is slightly higher than the upper surface of the pressing platform, ensuring that it can contact PVC insulation boards of different thicknesses. When the four sets of correction plates converge inward at the same time, a forced centering area is formed, which completely eliminates the situation of misalignment or skewed placement of multi-layer insulation materials.

[0016] Furthermore, the distance between the drive plate and the extension plate and the fixed rod is less than the maximum movement length of the drive plate and the extension plate.

[0017] By adopting the above technical solution, the total length of the drive plate and the extension plate is less than its maximum stroke, thus avoiding rigid collision between the correction mechanism and the fixed rod when the correction mechanism moves to the limit position.

[0018] Furthermore, the distance between the bottom of the movable seat and the bottom of the inner wall of the pressing table is greater than the maximum stroke of the electric push rod.

[0019] By adopting the above technical solution, a safety gap is reserved at the bottom of the movable seat to ensure that the electric push rod will not collide with the pressing table base when it is in full stroke operation.

[0020] The beneficial effects of this utility model are as follows: 1. By setting up a pressing zone, the thermal insulation material is placed into the predetermined pressing zone before pressing, which can improve the accuracy of the correction and enable the pressing plate to press the thermal insulation material in the pressing zone directly, avoiding uneven pressing force that would lead to uneven pressing of the thermal insulation material.

[0021] 2. This utility model, through the setting of the correction mechanism, can correct the insulation material placed in the pressing area before pressing. When the four sets of correction plates converge inward simultaneously, a forced centering area is formed, which completely eliminates the situation of misalignment or skewed placement of multi-layer insulation materials, avoids the deformation of insulation materials and uneven pressing, and avoids the problem of air bubbles inside multi-layer insulation materials, which greatly reduces the insulation effect.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] Reference Figures 1-4 This utility model embodiment proposes a thermal insulation material pressing device, including a pressing table 1. Support columns 2 are fixed at the four corners of the upper surface of the pressing table 1. A top plate 3 is fixed at the top of the support columns 2. A hydraulic cylinder 4 is installed on the lower side of the top plate 3. A pressing plate 5 is installed at the output end of the hydraulic cylinder 4. A pressing area 6 is provided in the middle of the pressing table 1. A slide 61 is provided on the upper surface of the pressing table 1, which connects to the inside of the pressing area 6. The slide 61 extends from one end toward the center of the pressing table 1 to the edge of the pressing area 6. The slide 61 is four sets of radially opened straight guide grooves. Its width is matched with the clearance of the correction mechanism 7 so that the correction mechanism 7 does not shake when moving horizontally. When the thermal insulation board is placed off-center, the correction mechanism 7 can extend precisely along the slide 61 to the surface of the pressing table 1 and forcefully push the position of the thermal insulation board to correct it, so as to avoid uneven heat melt flow during pressing due to misalignment of the PVC decorative layer.

[0026] Reference Figures 1-4 Inside the pressing table 1, a correction mechanism 7 is located directly below the pressing area 6. The correction mechanism 7 includes a fixed seat 71, a fixed rod 72 fixed in the middle of the fixed seat 71, and the fixed rod 72 fixed to the top of the inner wall of the pressing table 1. A movable seat 73 is provided at the bottom of the fixed seat 71. The fixed seat 71 and the movable seat 73 are connected by an electric push rod 74. An upwardly extending L-shaped limiting plate 75 is integrally formed on the periphery of the movable seat 73. A first movable groove 751 is provided in the middle of the upward-facing end of the limiting plate 75. When the electric push rod 74 retracts or pushes outward, it can drive the movable seat 73 to move up or down. The pure mechanical transmission ratio is 1:2.5, ensuring a rapid response to the offset PVC insulation board.

[0027] Reference Figures 1-4A protrusion 711 is fixed on the upper surface of the fixed base 71, a slider 712 slides on the protrusion 711, an L-shaped drive plate 76 is fixed on the slider 712, the drive plate 76 is arranged opposite to the limiting plate 75, a second movable groove 761 is provided in the middle of the downward end of the drive plate 76, an extension plate 77 is fixed on the upper surface of the drive plate 76, a correction plate 78 extends upward from the end of the extension plate 77 away from the fixed rod 72, the drive plate 76 and the extension plate 77 adopt an integrated L-shaped structure, the drive plate 76 forms a sliding pair with the protrusion 711 through the slider 712, and the correction plate 78 extends upward from the other end of the drive plate 76. When the drive plate 76 moves horizontally under the drive of the slider 712, the extension plate 77 transmits force to the correction plate 78, causing it to move radially synchronously within the slide rail 61. The correction plate 78 extends through the slide rail 61 to the upper surface of the pressing table 1. The bottom of the correction plate 78 is slightly higher than the upper surface of the pressing table 1 to ensure contact with PVC insulation boards of different thicknesses. When the four sets of correction plates 78 converge inward synchronously, a forced centering area is formed, completely eliminating the situation of misalignment or skewed placement of multi-layer insulation materials. A polyurethane buffer layer is attached to the working surface of the correction plate 78 to prevent scratches on the surface when pushing the PVC panel.

[0028] Reference Figures 1-4 A connecting plate 79 is movably connected between the first movable groove 751 and the second movable groove 761. The two ends of the connecting plate 79 are respectively hinged to the first movable groove 751 and the second movable groove 761 by pins. When the limiting plate 75 moves vertically with the movable seat 73, the tilt angle of the connecting plate 79 changes. Through the hinge action between the first movable groove 751 and the connecting plate 79, and between the other end of the connecting plate 79 and the second movable groove 761, the vertical movement of the movable seat 73 is converted into the horizontal movement of the slider 712, thereby causing the drive plate 76 to slide radially along the protrusion 711.

[0029] Reference Figures 1-4 The distance between the drive plate 76 and the extension plate 77 and the fixed rod 72 is less than the maximum movement length of the drive plate 76 and the extension plate 77, and the total length of the drive plate 76 and the extension plate 77 is less than its maximum stroke. This avoids a rigid collision between the correction mechanism 7 and the fixed rod 72 when the correction mechanism 7 moves to its limit position. The distance between the bottom of the movable seat 73 and the bottom of the inner wall of the pressing table 1 is greater than the maximum stroke of the electric push rod 74. A safety gap is reserved at the bottom of the movable seat 73 to ensure that the electric push rod 74 will not hit the base of the pressing table 1 when it is working at full stroke.

[0030] The specific implementation method is as follows: In use, when the multi-layer PVC insulation decorative board is placed on the pressing area 6 of the pressing table 1, the electric push rod 74 of the correction mechanism 7 is activated and pushed downward, thereby driving the movable seat 73 to move vertically downward, so that the integrally formed L-shaped limiting plate 75 moves downward synchronously; at this time, the two ends of the connecting plate 79 are respectively hinged to the first movable groove 751 of the limiting plate 75 and the second movable groove 761 of the driving plate 76. As the vertical displacement of the limiting plate 75 moves downward, the angle of the connecting plate 79 gradually becomes vertical, thereby pushing the driving plate 76 along the protrusion 711 towards the center under the action of the slider 712. The movement of the center forces the four sets of correction plates 78 to converge inwards synchronously along the slide 61. The polyurethane buffer layer attached to the working surface of the correction plate 78 contacts the edge of the PVC insulation board and applies radial thrust, which can force the board to be corrected to the center of the pressing area 6. After the positioning is completed, the hydraulic cylinder 4 drives the pressing plate 5 to press down. At this time, the multi-layer insulation material is precisely stacked, eliminating interlayer bubbles caused by misalignment of PVC layers. After the pressing is completed, the electric push rod 74 retracts to reset the movable seat 73, and the tilt angle of the connecting plate 79 gradually increases, driving the correction plate 78 to exit radially. During this process, a safety gap is reserved to avoid collision of the mechanism.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
