Description

Technical Field

[0001] The present invention relates to the technical field of pressing of thermal insulation boards, and particularly to a pressing device for multi-layer fireproof and heat-insulating thermal insulation boards. Background Technique

[0002] A thermal insulation board, also known as a heat-insulating board, is a building material or industrial material used to reduce heat transfer and maintain temperature stability. The main function of the thermal insulation board is to prevent heat transfer between different temperature regions, playing a role in heat insulation and temperature preservation. The thermal insulation board is usually made of materials with low thermal conductivity, such as organic or inorganic materials like polystyrene, polyurethane, rock wool, glass wool, etc. During the production process of the thermal insulation board, it generally goes through two steps: cold pressing and hot pressing. Cold pressing is to combine the thermal insulation material and the decorative panel under normal temperature through high pressure. First, a special adhesive is evenly applied on the contact surface between the thermal insulation material and the decorative panel, and then it is placed in a cold press and tightly combined through high pressure, and then cured under specific conditions. Hot pressing is to tightly combine the thermal insulation material, the decorative panel, etc. through high temperature and high pressure. Usually, adhesives such as melamine resin glue need to be applied between the thermal insulation material and the panel, and under high temperature conditions, the rapid curing is achieved through the chemical reaction of the adhesive at high temperature.

[0003] In the existing cold pressing process, a cold press is required for cold pressing. However, the time required for the thermal insulation board during cold pressing is relatively long. In order to improve production efficiency, multiple cold presses are often purchased for cold pressing. However, this method will increase the production cost of the equipment, and the energy consumption is also large when multiple cold presses work together. In addition, when the existing thermal insulation board is transported to the hot press, it is often necessary to move the thermal insulation board layer by layer to the hot press, and its transportation efficiency is slow, which is a waste of time in large-scale production. Summary of the Invention

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0037] Please refer to Figure 1-12 , the present invention provides a technical solution: a pressing device for a multi-layer fireproof, heat-insulating and heat-preserving board, including an installation base plate 1, an installation base 2 is fixedly installed on the installation base plate 1, two groups of moving grooves 3 are opened on the lower side of the installation base 2, a plurality of pressing plates 4 are arrayed and installed on the upper side of the installation base 2, and an installation top plate 5 is fixedly installed on the uppermost pressing plate 4;

[0038] Adjusting mechanism 6, the adjusting mechanism 6 includes a hinge group 601 and a connecting shaft 603. The hinge group 601 is arranged on both sides of the pressing plate 4, and the connecting shaft 603 is fixedly installed at the rotating shaft of the hinge group 601;

[0039] Guiding mechanism 7, the guiding mechanism 7 includes a mounting frame 701 and a guiding rod 704. The mounting frame 701 is installed on the pressing plate 4, and the guiding rod 704 is movably installed on the mounting frame 701;

[0040] Discharging mechanism 8, the discharging mechanism 8 includes a second mounting block 801 and a discharging rod 802. The second mounting block 801 is fixedly installed on the mounting frame 701, and the discharging rod 802 is movably installed on the mounting frame 701;

[0041] Locking mechanism 9, the locking mechanism 9 includes a sleeve 901 and a sleeve rod 902. The sleeve 901 is fixedly installed at the four corners of the mounting base plate 1, and the sleeve rod 902 is movably inserted into the sleeve 901;

[0042] Lifting mechanism 10, the lifting mechanism 10 includes a fourth movable plate 1002 and a support leg 1003. The fourth movable plate 1002 is slidably installed between the sleeves 901, and the support leg 1003 is fixedly installed on the lower side of the fourth movable plate 1002. Through the locking mechanism 9 of this equipment, the heat preservation board between the pressing plates 4 can be continuously pressed without cold pressing. In addition, through the mutual cooperation among the adjusting mechanism 6, the discharging mechanism 8 and the locking mechanism 9, the heat preservation board can be quickly placed into the hot press. Moreover, most of the mechanisms of this equipment can be disassembled, thus realizing convenient maintenance during the use of the equipment.

[0043] Furthermore, the adjusting mechanism 6 further includes a rotating groove 602 and a first gear 604. Two sets of hinge groups 601 are arranged on the left and right sides of the two groups of pressing plates 4. Two sets of rotating grooves 602 are opened on the front and rear sides of the pressing plate 4. The connecting shaft 603 is rotatably installed in the rotating groove 602. The first gears 604 are fixedly installed at the upper and lower ends of the hinge group 601, and the first gears 604 on the upper and lower hinge groups 601 are meshed with each other. The specific schematic diagram of this structure is Figure 4, the specific function of this structure is to enable the pressing plate 4 to open synchronously. The hinge group 601 is composed of four connecting rods with rounded ends at both ends. The four connecting rods have the same shape and size, and the ends of the connecting rods are rotatably connected to each other. Two connecting rods are in the front and the other two are at the back. The first gear 604 is fixedly installed at the end of the front connecting rod. The advantage of this structure compared with a general rhombic telescopic rod is that the transmission between the hinge groups 601 is achieved through the first gear 604, and the upper and lower sides of each hinge group 601 are rotatably installed on the pressing plate 4, and most of the forces received can be borne by the connecting shaft 603. For the lifting transmission of a general rhombic telescopic rod, the rigidity requirement of its own material is relatively high. When the load is large, the material may deform. Moreover, after part of the rhombic telescopic rod is damaged, the whole cannot be used and the whole needs to be replaced, resulting in a high maintenance cost;

[0044] Further, the adjusting mechanism 6 further includes a limit frame 605, a first motor 606, a first slider 607, a first screw sleeve 608, a first screw rod 609, a hinge rod 610, a rubber pad 611 and a pressure sensing remote controller 612. Limit frames 605 are fixedly installed on both the left and right sides of the mounting base plate 1 and the pressing plate 4 in the middle. A first motor 606 is fixedly installed at the center position of the limit frame 605. A first screw rod 609 is fixedly installed on the output shaft of the first motor 606. Two first sliders 607 are slidably installed in the limit frame 605. A first screw sleeve 608 is fixedly installed at the center position of the first slider 607. The first screw sleeve 608 is sleeved on the first screw rod 609 through a thread. Hinge rods 610 are hinged on the first sliders 607. One end of the hinge rod 610 is hinged on the hinge group 601. A rubber pad 611 is fixedly installed at the center position of the upper end of the mounting top plate 5. A pressure sensing remote controller 612 is fixedly installed in the rubber pad 611. The specific schematic diagram of the structure is Figure 4 and Figure 9, the specific function of this structure is to drive the hinge group 601 to open or contract. A first motor 606 is provided on both the mounting base plate 1 and the pressing plate 4. The first motor 606 on the upper side is to reduce the driving pressure of the first motor 606 on the lower side, so they are synchronous during use. The pressure sensing remote controller 612 is used to sense the change of pressure. Its specific function is to control the first motor 606 to start when detecting an increase in pressure, so as to realize the downward pressing of the auxiliary pressing plate 4. At the same time, it can avoid the situation that the hinge group 601 or the hinge rod 610 breaks due to the first motor 606 not working when the equipment is pressed by the cold press. The existence of the rubber pad 611 can avoid the pressure sensing remote controller 612 from bearing excessive pressure through its own deformation. This structure makes the hinge group 601 have a greater and more stable bearing capacity through the support method of simultaneously supporting the two hinge groups 601. And the additional first motor 606 on the upper side is used for relaying the supporting force of the hinge group 601, so that the pressing plates 4 can open more quickly and stably during use, and the equipment itself has a stronger bearing capacity;

[0045] Further, the guiding mechanism 7 further includes a first sliding groove 702, a second sliding block 703, a triangular marking groove 705, a scale 706, a first mounting block 707, a second screw rod 708, a mounting groove 709, and a second screw sleeve 710. A first sliding groove 702 is opened on the upper side of the mounting frame 701. Two second sliding blocks 703 are slidably mounted in the first sliding groove 702. Guide rods 704 are fixedly mounted on the second sliding blocks 703. The guide rods 704 are located on the upper side of the pressing plate 4. A triangular marking groove 705 is opened on the upper side of the second sliding block 703. Scales 706 are arrayed and opened on the upper side of the mounting frame 701. First mounting blocks 707 are fixedly mounted on the left and right sides of the mounting frame 701. A second screw rod 708 is movably inserted into the first mounting block 707. Two mounting grooves 709 are opened on both sides of the rear ends of the pressing plate 4 and the mounting base plate 1. Second screw sleeves 710 are fixedly mounted in the mounting grooves 709. The second screw rod 708 is threadedly mounted in the second screw sleeve 710. The specific schematic diagram of the structure is Figure 5 , the specific function of this structure is to enable the insulation board to be guided by the guide rods 704 when placed on the pressing plate 4. The existence of the triangular marking groove 705 and the scale 706 can intuitively reflect the specific position of the guide rods 704. In addition, the mounting frame 701 can be disassembled, so that the guiding mechanism 7 can be conveniently replaced when a malfunction or damage occurs, reducing the use cost of the equipment. The distance between the two pressing plates 4 is smaller than the thickness of the insulation board, and the height of the guide rods 704 is also less than half of the thickness of the insulation board;

[0046] Further, the guiding mechanism 7 further includes a rack 711, a second gear 712, a first movable groove 713, a first movable rod 714, a limiting plate 715, a first spring 716, a first knob 717, a clamping ring 718 and an annular clamping groove 719. A rack 711 is fixedly installed on the lower side of each of the two second sliders 703. The two racks 711 are movable within the mounting frame 701. The teeth of the two racks 711 face each other. A second gear 712 is rotatably installed at the central position of the mounting frame 701. The second gear 712 meshes with the two racks 711. A first movable groove 713 is formed in the second gear 712. A first movable rod 714 is movably inserted into the first movable groove 713. A limiting plate 715 is fixedly installed at one end of the first movable rod 714. The shape of the first movable groove 713 is adapted to the shape of the limiting plate 715. A first spring 716 is sleeved on the first movable rod 714. One side of the first spring 716 abuts against the inner side of the first movable groove 713. A first knob 717 is fixedly installed at the other end of the first movable rod 714. A clamping ring 718 is fixedly installed on the first knob 717. An annular clamping groove 719 is formed in the mounting frame 701. The clamping ring 718 is clamped in the annular clamping groove 719. The specific schematic diagram of the structure is Figure 5 and Figure 10 , and the specific function of this structure is to adjust the distance between the guide rods 704. By rotating the second gear 712, the two racks 711 can move synchronously, so as to realize the function of adjusting the distance between the guide rods 704. The first knob 717 can not only control the rotation of the second gear 712, but also expand and contract relative to the second gear 712. Therefore, in the normal state, the clamping ring 718 is clamped in the annular clamping groove 719, so that the first knob 717 cannot rotate, thus realizing the locking of the position of the guide rod 704. When the second gear 712 needs to be rotated, the first knob 717 can be pulled to disengage the clamping ring 718 from the annular clamping groove 719, so that the second gear 712 can be driven to rotate by the first knob 717. The upper rack 711 is narrower than the lower rack 711, and a groove adapted to the upper rack 711 is formed at the connection between the lower rack 711 and the second slider 703, so that the upper rack 711 can pass through the connection, increasing the relative movement range of the racks 711, and thus increasing the movement range of the guide rod 704;

[0047] Further, the discharging mechanism 8 further includes a mounting bracket 803, a hydraulic oil pipe 804, and a hydraulic oil rod 805. The ends of the discharging rod 802 are all rounded. The length of the discharging rod 802 is half of the length of the pressing plate 4. A mounting bracket 803 is fixedly installed on the middle mounting frame 701. A hydraulic oil pipe 804 is fixedly installed on the mounting bracket 803. Two groups of hydraulic oil rods 805 are rotatably installed on the mounting bracket 803. The hydraulic oil pipe 804 is connected to the hydraulic oil rods 805 through a transmission pipe. The ends of the two groups of hydraulic oil rods 805 are hinged to the discharging rod 802. The specific schematic diagram of this structure is Figure 6 , and the specific function of this structure is to drive the discharging mechanism 8 to expand. The way of expanding through the hydraulic oil rod 805 has a stronger pushing ability, so that the heat preservation board on the pressing plate 4 can be smoothly pushed out. And the discharging rod 802 is located above the guiding rod 704, so the activities of the two will not block each other, and the discharging rod 802 can contact the rear side of the heat preservation board;

[0048] Further, the discharging mechanism 8 further includes a mounting shaft 806, a flower-shaped groove 807, and a flower-shaped rod 808. A mounting shaft 806 is fixedly installed at the end of the discharging rod 802. The mounting shaft 806 is rotatably installed in the second mounting block 801. Flower-shaped grooves 807 are formed on both the discharging rod 802 and the mounting shaft 806. A flower-shaped rod 808 is fixedly installed at the lower end of the mounting shaft 806. The flower-shaped rod 808 is inserted into the flower-shaped grooves 807 formed on the lower discharging rod 802 and the mounting shaft 806. The specific schematic diagram of this structure is Figure 6 and Figure 11 , and the specific function of this structure is to enable multiple discharging rods 802 to rotate synchronously, and this kind of transmission will not be interrupted when the pressing plate 4 moves relatively, so as to realize the synchronous rotation of the discharging rods 802, so that the heat preservation boards on the pressing plate 4 can be discharged synchronously, increasing the efficiency of the equipment when transporting the heat preservation boards. The length of the flower-shaped rod 808 is less than the maximum distance between the pressing plates 4, which can make the flower-shaped rod 808 be completely withdrawn. Since the guiding mechanism 7 can be disassembled, and the discharging mechanism 8 is installed on the guiding mechanism 7, the guiding mechanism 7 and the discharging mechanism 8 can be disassembled synchronously;

[0049] Further, the locking mechanism 9 further includes a mounting box 903, a first movable plate 904, a second movable rod 905, a second spring 906, a second movable plate 907, a triangular block 908, a clamping groove 909, a third mounting block 910, a third screw rod 911 and a third screw sleeve 912.

Triangular blocks 908 are fixedly installed on the second movable plate 907 in an array. The hypotenuse of the triangular block 908 faces upward. Clamping grooves 909 are arranged in an array on one side of the sleeve rod 902. The triangular blocks 908 are clamped in the clamping grooves 909. Third mounting blocks 910 are fixedly installed at the ends of the sleeve 901 and the sleeve rod 902. Third screw rods 911 are movably inserted at the four corners of the third mounting block 910. Four groups of third screw sleeves 912 are fixedly installed at the four corners of the opposite sides of the mounting bottom plate 1 and the mounting top plate 5. The third screw rod 911 is installed in the third screw sleeve 912 by means of a thread. The specific schematic diagram of this structure is Figure 7 and Figure 12 , the specific function of this structure is to lock the distance between the pressing plates 4 through the self-locking between the sleeve 901 and the sleeve rod 902. When the mounting top plate 5 is squeezed by the cold press, the sleeve rod 902 descends, so that the second movable plate 907 moves horizontally, and the triangular block 908 is clamped in the next clamping groove 909 under the action of the second spring 906 for locking, so as to realize pressing instead of the cold press, so that the cold press does not need to continuously apply force to the insulation board, so as to reduce the demand for the cold press in the mass production process, save the use cost of the equipment, and the overall locking of the equipment not only depends on the mutual clamping between the clamping groove 909 and the triangular block 908, but also the adjusting mechanism 6 itself has a locking effect on the equipment, so that the locking of the equipment is more stable, and the sleeve 901 and the sleeve rod 902 can also be disassembled and can be conveniently replaced when damaged;

[0050] Further, the locking mechanism 9 further includes a connecting plate 913, a third movable plate 914, a calabash groove 915, a limiting rod 916 and a second knob 917. The connecting plate 913 is fixedly installed between the mounting boxes 903 on the same side, and the third movable plate 914 is fixedly installed between the second movable rods 905 on the same side. A calabash groove 915 is formed at the center of the connecting plate 913, and a limiting rod 916 is rotatably installed at the center of the third movable plate 914. The end of the limiting rod 916 has a protrusion, and the shape of the limiting rod 916 is adapted to the shape of the calabash groove 915. The limiting rod 916 is inserted into the calabash groove 915, and the other end of the limiting rod 916 is fixedly installed with a second knob 917. The specific schematic diagram of this structure is Figure 7 and Figure 8 , and the specific function of this structure is to continuously release the locking function of the locking mechanism 9, so that the distance between the pressing plates 4 can be normally adjusted, and at the same time, the unlocking of the locking mechanism 9 is more convenient;

[0051] Further, the lifting mechanism 10 further includes a telescopic motor 1001 and a second movable groove 1004. The telescopic motor 1001 is fixedly installed on the connecting plate 913, and a fourth movable plate 1002 is fixedly installed on the output shaft of the telescopic motor 1001. Two groups of second movable grooves 1004 are formed on the left and right sides of the mounting base plate 1, and the support legs 1003 are inserted into the second movable grooves 1004, and anti-slip pads are fixedly installed on the lower sides of the support legs 1003. The specific schematic diagram of this structure is Figure 3 and Figure 7 , and the specific function of this structure is to enable the whole device to be lifted, so as to adapt to the height of hot pressing. The distance between the pressing plates 4 can be adjusted by the adjusting mechanism 6. Therefore, the insulation board on the device can be directly opposite to the placement groove of the hot press, and then pushed into the hot press through the discharging mechanism 8 to realize the rapid placement of the insulation board. At the same time, the lifting mechanism 10 is also installed based on the locking mechanism 9, so it can also be disassembled following the locking mechanism 9.

[0052] Working principle: When the present invention is in use, first start the first motor 606. The output shaft of the first motor 606 rotates to drive the first screw rod 609 to rotate. Thus, through the threaded action with the first nut 608, the first slider 607 moves relatively away, making the articulated rod 610 gradually vertical, and then propping up the articulated group 601. The articulated group 601 extends, and the connecting rods forming the articulated group 601 rotate. Therefore, the first gear 604 provided on the articulated group 601 rotates to drive another group of first gears 604 to rotate, so that another group of articulated groups 601 extends synchronously, thereby realizing the adjustment of the distance between the pressing plates 4.

[0053] Before adjusting the distance between the pressing plates 4, it is necessary to pull the third movable plate 914 so that the second movable rod 905 is pulled. At this time, the triangular block 908 disengages from the engaging groove 909, and the limiting rod 916 disengages from the calabash groove 915. Then, rotate the second knob 917 so that the protrusion on the limiting rod 916 abuts against the connecting plate 913, realizing the locking of the position of the second movable plate 907, so that the sleeve rod 902 can move normally.

[0054] Then, under the guidance of the guiding mechanism 7, place the heat preservation plate on the pressing plate 4. When it is necessary to adjust the position of the guiding rod 704, pull the first knob 717 so that the engaging ring 718 disengages from the annular slot 719. At this time, the first spring 716 is compressed. Then, rotate the first knob 717, thereby driving the second gear 712 to rotate. The second gear 712 drives the rack 711 to move relatively through the meshing with the rack 711, thereby driving the second slider 703 and the guiding rod 704 to move, realizing the adjustment of the distance between the guiding rods 704. The relative position of the triangular marking groove 705 and the scale 706 can be observed to obtain the value of the distance between the guiding rods 704.

[0055] Then, the equipment can be moved by inserting the forklift's fork into the moving groove 3. Move the equipment to the cold press. Rotate the second knob 917 so that the limiting rod 916 conforms to the shape of the calabash groove 915, and the limiting rod 916 is reinserted into the calabash groove 915 under the action of the second spring 906. Then, the cold press applies pressure. The pressure sensing remote controller 612 detects the increase in pressure, causing the output shaft of the first motor 606 to reverse, so that the articulated rod 610 pulls the articulated group 601 to contract, thereby cooperating with the reduction of the distance between the pressing plates 4. The sleeve rod 902 moves relative to the sleeve 901, causing the second movable plate 907 to move towards the installation box 903 under the action of the inclined surface of the triangular block 908, and then re-engaging in the engaging groove 909 under the restoring force of the second spring 906. After the cold press applies the appropriate force, the pressure application ends. At this time, the locking mechanism 9 and the adjusting mechanism 6 can lock the distance between the pressing plates 4, thereby applying pressure to the pressing plates 4 for a long time. When releasing the pressure, unlock the locking mechanism 9. The unlocking principle is the same as above, and then make the output shaft of the first motor 606 rotate forward.

[0056] After the cold pressing is completed, the equipment is moved to the hot press by a forklift. Then, the telescopic motor 1001 is started, and the output shaft of the telescopic motor 1001 extends, so that the fourth movable plate 1002 descends, and the support leg 1003 moves in the second movable groove 1004 and contacts the ground to lift the entire equipment until the upper side of the mounting base plate 1 is flush with the lower side of the placement groove at the lowest side of the hot press. Then, the distance between the pressing plates 4 is controlled by the adjusting mechanism 6, so that the insulation board is opposite to the placement groove of the hot press. Then, the hydraulic oil pipe 804 is started, and the hydraulic oil rod 805 extends, so that the discharge rod 802 rotates away. At this time, the discharge rods 802 of different groups are driven by being inserted into the flower-shaped grooves 807 through the flower-shaped rods 808. When the discharge rod 802 rotates, it will push the insulation board into the placement groove of the hot press. The reset is the same.

[0057] When the guiding mechanism 7 needs to be disassembled, unscrew the second screw rod 708 so that the second screw rod 708 disengages from the second screw sleeve 710, and then the mounting frame 701 can be pulled out; when the locking mechanism 9 needs to be disassembled, unscrew the third screw rod 911 from the third screw sleeve 912 to complete the disassembly.
