Description

Technical Field

[0001] The invention relates to the technical field of plate processing, in particular to a pressing device for producing nano heat insulation boards. Background Art

[0002] At present, when producing nano thermal insulation boards, multiple nano boards need to be bonded and pressed together.

[0003] However, most of the existing pressing equipment uses hydraulic or pneumatic pressure to drive the pressing plate to pressurize the stacked nano-sheets. The pressing rod is connected to the middle of the top of the pressing plate. The pressing force of the hydraulic rod and the pressing plate on the nano-sheet is mainly concentrated in the middle of the lower end of the pressing plate. The pressing force at the edge of the pressing plate is relatively weak, and the pressing effect on the edge of the nano-sheet is poor, which can easily cause the edge connection of the nano-sheet to be loose and cracked, affecting the production quality of the nano-sheet.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0022] According to the following Figure 1-Figure 15 The present invention describes a pressing device for producing a nano thermal insulation board provided in an embodiment of the present invention. Example

[0023] See also Figure 1-Figure 3The embodiment of the present invention provides a technical solution: a pressing device for producing nano thermal insulation boards, comprising a workbench 100, the workbench 100 comprising a base 110, a top plate 130 located above the base 110, and a rear support plate 120 located at the rear side of the base 110 for connecting the base 110 and the top plate 130; a compression cylinder 200 is installed on the top plate 130, the compression cylinder 200 can be a cylinder or a hydraulic cylinder, a pressure seat 500 is fixed at the lower end of the piston rod of the compression cylinder 200, and a pressing plate 600 is provided below the pressure seat 500; wherein, the nano thermal insulation board is located on the upper surface of the base 110, the pressing plate 600 is located above the nano thermal insulation board to be pressed, and the pressing plate 600 can press the nano thermal insulation board when pressed down.

[0024] like Figure 2 The lower surface edge area of ​​the pressure seat 500 is connected to the pressing plate 600 through an elastic connector 800. When the compression cylinder 200 extends downward, it can drive the entire pressing plate 600 and the pressure seat 500 to move downward until the pressing plate 600 is pressed on the upper surface of the nano-insulation board. As the compression cylinder 200 continues to extend, the pressure seat 500 compresses the elastic connector 800 and continues to move downward to provide pressure to the pressing plate 600.

[0025] like Figure 2-Figure 4 As shown, a wedge block 700 is also provided, and the wedge blocks 700 are distributed on both sides of the middle area of ​​the upper surface of the pressing plate 600. The upper surface of the wedge block 700 has a slope 710. A third spring 630 is fixedly provided below the side of the wedge block 700 away from the center of the pressing plate 600. The upper limit of the wedge block 700 in the vertical direction is located on the pressing plate 600. An extrusion cavity 520 is provided in the pressure seat 500, and thrust blocks 530 are provided on both sides of the upper part of the extrusion cavity 520 near the middle. 30. The upper part of the wedge block 700 is located in the extrusion cavity 520. When the pressure seat 500 descends, it can extrude the slope 710 through the thrust block 530, so that the wedge block 700 can be subjected to forces in both horizontal and vertical directions. The vertical force exerted on the wedge block 700 is used to extrude the pressing plate 600, and the horizontal force exerted on the wedge block 700 is used to move the wedge block 700 outward on the upper surface of the pressing plate 600 to expand the pressure range on the pressing plate 600.

[0026] Therefore, when the pressing device for producing the nano thermal insulation board provided in the embodiment of the present invention is pressed, since the wedge block 700 is subjected to horizontal and vertical forces, on the one hand, it can apply pressure to the middle part of the pressing plate 600, thereby pressing the nano thermal insulation board, and on the other hand, it can produce horizontal movement to adjust its own pressing position, thereby greatly expanding the pressing range.

[0027] Preferably, the lower surface of the wedge block 700 should be a smooth surface after grinding and polishing, or have a roller structure to reduce the wear caused by the relative movement between the wedge block 700 and the pressing plate 600.

[0028] Combination Figure 5-Figure 8 As shown, preferably, the above-mentioned extrusion chamber 520 is provided with multiple, and the multiple extrusion chambers 520 are spaced apart in the pressure seat 500, and the wedge blocks 700 are provided with multiple, and the multiple wedge blocks 700 on one side are arranged side by side and ingested into the relative extrusion chamber 520, and a bottom connecting seat 730 is fixed between the lower ends of the wedge blocks 700 on one side. By adopting this interlaced assembly method, there is no need to set the pressure seat 500 as a complete cavity, thereby enhancing the strength of the pressure seat 500.

[0029] In addition, a groove 620 is provided in the middle of the upper surface of the pressing plate 600, and the lower part of the wedge block 700 is located in the groove 620. A third guide rod 640 is fixed in the groove 620 along the moving direction of the wedge block 700. A guide hole 740 is provided on the bottom connecting seat 730 at a position opposite to the third guide rod 640, and the third guide rod 640 is located in the guide hole 740. The wedge block 700 and the bottom connecting seat 730 can slide on the third guide rod 640. This method can not only position the entire wedge block 700 and the bottom connecting seat 730 on the pressing plate 600 in the vertical direction, but also guide the expansion and contraction of the third spring 630. Preferably, the third spring 630 is sleeved on the third guide rod 640, one end of which is fixed in the guide hole 740, and the other end is fixed on the inner wall of the groove 620.

[0030] like Fig. 9 As shown, preferably, the above-mentioned elastic connecting member 800 includes a compression spring 810 and a fourth guide rod 820, one end of the compression spring 810 is fixedly connected to the pressing plate 600, and the other end of the compression spring 810 is fixedly connected to the pressure seat 500, one end of the fourth guide rod 820 is fixed on the pressing plate 600, and the other end of the fourth guide rod 820 is fixedly provided with a limiting head 830, a limiting guide hole 550 is opened in the pressure seat 500, and the limiting head 830 is captured in the limiting guide hole 550.

[0031] In this embodiment, when the pressure seat 500 moves downward, the pressure seat 500 squeezes the compression spring 810 downward, and the limit head 830 continues to enter the limit guide hole 550 to guide the expansion and contraction of the compression spring 810 and maintain the relative position of the pressure seat 500 and the pressing plate 600. Example

[0032] The above embodiment is suitable for nano-insulation boards of smaller sizes. This is because the distance between the pressing plate 600 and the pressure seat 500 is limited (if the distance between the two is too large, the overall height of the equipment will be larger, the elongation length of the compression cylinder 200 will be larger, and its stability will be reduced). The limited distance causes the pressure seat 500 to be able to descend a smaller distance relative to the pressing plate 600, resulting in a shorter distance that it can push the wedge block 700 to move horizontally, making it difficult for the wedge block 700 to reach the edge of the pressing plate 600, thereby reducing the force on the edge of the nano-insulation board.

[0033] Therefore, this embodiment only adds the following content on the basis of the first embodiment to solve the problem that the edge position of the larger-sized nano-insulation board is subjected to reduced force.

[0034] like Figure 1 , Figure 2 , Fig.10 As shown, it specifically includes a side pressure assembly 300 , a through hole 610 and a push plate 900 .

[0035] Among them, the side pressure assembly 300 is located on both sides above the base 110, and the side pressure assembly 300 is hoisted under the top plate 130 through the hoisting frame 400. The side pressure assembly 300 is a structure that can be opened and closed in the horizontal direction, and the through hole 610 is opened in the area opposite to the side pressure assembly 300 on the pressing plate 600. When the side pressure assembly 300 is closed, the side pressure assembly 300 can pass through the through hole 610. When the pressing plate 600 presses the nano thermal insulation board, the side pressure assembly 300 can be opened and sit in the area where the through hole 610 is located, and provide pressure to the pressing plate 600, so that there is no need to use the pressure of the compression cylinder 200 to achieve the force applied to the edge area of ​​the nano thermal insulation board, thereby improving the pressing degree of the edge area of ​​the nano thermal insulation board.

[0036] The push plate 900 here is installed on the side of the wedge block 700 away from the center of the pressure seat 500. When the wedge block 700 moves horizontally, the push plate 900 can apply force to the side pressure assembly 300 to open the side pressure assembly 300. In summary, the thrust generated by the horizontal movement of the wedge block 700 is used as the power for the side pressure assembly 300 to open, so that when the side wedge block 700 presses the near-central area of ​​the nano-insulation board, the side pressure assembly 300 can apply force to press the edge of the nano-insulation board.

[0037] It should be noted that since the push plate 900 needs to extend out of the pressure seat 500, and the push plate 900 and the pressure seat 500 will have a relative displacement in the vertical direction relative to the push plate 900, a compensation track needs to be opened on the pressure seat 500 at a position opposite to the push plate 900 for the push plate 900 to slide.

[0038] For details, refer to 10- Fig.12As shown, the side pressure assembly 300 includes a pressure spring 330 , a fixed rod 320 and a wedge block 350 .

[0039] The upper end of the pressure spring 330 is fixed with a first spring seat 310, and the first spring seat 310 is fixedly connected to the lower end of the hanging frame 400. The lower end of the pressure spring 330 is fixed with a second spring seat 340. The fixed rod 320 is located between the first spring seat 310 and the second spring seat 340, and the fixed rod 320 is arranged in a circular matrix. The upper end of the fixed rod 320 is fixed on the first spring seat 310, and the lower end of the fixed rod 320 is provided with a ball head 321. The second spring seat 340 is a cavity structure. The wedge blocks 350 are radially arranged in the cavity structure, and the wedge blocks 350 extend out of the second spring seat 340 on the side away from the center of the second spring seat 340. When the wedge blocks 350 extend outward from the second spring seat 340, the circular diameter formed by the outer edges of the plurality of wedge blocks 350 should be greater than the diameter of the through hole 610, so the plurality of wedge blocks 350 can be mounted on the periphery of the through hole 610. This state is the open state of the side pressure assembly 300.

[0040] In order to release the pressure of the pressure spring 330 when the wedge block 350 is opened, the upper surface of the wedge block 350 has a second slope 351, the higher end of the second slope 351 is close to the second spring seat 340, the second slope 351 is provided with an inclined limiting groove 352, the lower end of the second slope 351 is provided with a straight portion 354, the straight portion 354 is provided with a straight limiting groove 355, and the ball head 321 can be in the straight limiting groove 355 and the inclined limiting groove 352. Inward sliding, that is, when the side pressure assembly 300 is in a closed state (wedge block 350 has not started to move outward), the ball head 321 is located in the straight limit groove 355, and the pressure spring 330 is in an energy storage state. When the wedge block 350 starts to move outward, the ball head 321 gradually moves into the inclined limit groove 352, and the pressure spring 330 is in an energy release state. The second spring seat 340 applies additional pressure to the edge position of the pressing plate 600 through the wedge block 350.

[0041] In order to achieve the purpose of automatically extending the above-mentioned wedge block 350 outward, a rotating disk 370 is also provided here. The rotating disk 370 is assembled at the axis center of the second spring seat 340 through a rotating shaft, and a protrusion 371 is provided on the arc surface of the rotating disk 370. When the rotating disk 370 rotates, the protrusion 371 can push the wedge block 350, so that the wedge block 350 can move radially along the second spring seat 340, forming an open state of the side pressure assembly 300. When the wedge block 350 moves radially along the second spring seat 340, the ball head 321 can enter the inclined limit groove 352 from the straight portion 354 to release the elasticity of the pressure spring 330; at this point, the downward pressing operation of the side pressure assembly 300 is completed.

[0042] like Fig.12 Preferably, the depth of the tilting limit groove 352 is greater than the diameter of the ball head 321, so that when the wedge block 350 is mounted on the pressing plate 600 but the push plate 900 continues to move horizontally, the ball head 321 can move downward relatively in the tilting limit groove 352, so that the pressure released by the pressure spring 330 acts completely on the pressing plate 600, instead of acting on the tilting limit groove 352 through the ball head 321.

[0043] Combination Figure 11-13 As shown, further, in order to realize the rotation of the above-mentioned rotating disk 370, the side pressure assembly 300 here also includes a transmission structure 390 and a gear column 360; the transmission structure 390 includes a driven gear 391 fixed to the upper end of the rotating shaft of the rotating disk 370, an acceleration gear 392 meshed with one side of the driven gear 391, and a driving gear 393 coaxial with the driven gear 391 and located at the lower end of the acceleration gear 392; the gear column 360 is meshed with the driving gear 393, and one end of the gear column 360 extends out of the second spring seat 340, so that the push plate 900 can push the gear column 360 when it moves horizontally.

[0044] In this embodiment, when the wedge block 700 gradually moves outward and is about to move to the edge area close to the groove 620, the push plate 900 can contact and push the gear column 360, so that the gear column 360 can drive the driving gear 393 to rotate, thereby realizing the rotation of the acceleration gear 392. When the acceleration gear 392 rotates, it can drive the driven gear 391 to rotate, thereby realizing the rotation of the rotating disk 370.

[0045] It should be noted that the acceleration gear 392 is added so that the rotating disk 370 can rotate to a sufficient angle to push the second wedge block 350 when the tooth column 360 moves a small distance.

[0046] Combination Fig.11 After the pressing is completed, the entire pressing plate 600 needs to move upward as the compression cylinder 200 shortens. In order to prevent the wedge block 350 from blocking the pressing plate 600 from moving upward, a second slider 353 is fixedly provided at the lower end of the wedge block 350 close to the rotating disk 370; a second guide rod 381 is fixedly provided on the bottom surface of the second spring seat 340 and the area opposite to the wedge block 350, and the second slider 353 can slide on the second guide rod 381, and a second spring 380 is provided between the second slider 353 and the inner wall of the second spring seat 340.

[0047] In this embodiment, when the rotating disk 370 rotates and pushes the wedge block 350, the second slider 353 is in a state of compressing the second spring 380. When the compression cylinder 200 is shortened, the entire pressure seat 500 first moves upward, so that the push plate 900 is upwardly disengaged from the gear column 360. At this time, the multiple second springs 380 are reset, thereby reversely driving the above-mentioned entire transmission structure 390, so that the ball head 321 returns to the straight limit groove 355, and the gear column 360 is reset.

[0048] Preferably, in order to avoid the situation where the second spring 380 is unable to reset the wedge block 350 due to excessive friction between the wedge block 350 and the pressing plate 600, a rotatable ball is provided on the lower surface of the wedge block 350 to reduce the friction between the two and ensure the reset of the wedge block 350; further, the second spring 380 adopts a spring with a larger stiffness coefficient; further, the central axis of the rotating disk 370 can also be assembled on the second spring seat 340 using a torsion spring. When the wedge block 350 is gradually extended, the torsion spring is in a gradually twisted state. Conversely, when the tooth column 360 loses pressure, the torsion spring is reset to make the transmission structure 390 work in reverse; further, a spring for resetting can be fixed between the pressure-bearing end of the tooth column 360 and the outer side wall of the second spring seat 340 to ensure the reset of the tooth column 360.

[0049] Preferably, the above-mentioned hanging bracket 400 includes an internal threaded tube 410 , a knob 420 , a limit head 440 and a hexagonal limit shaft 450 .

[0050] Specifically, the internal threaded barrel 410 is rotatably installed on the top plate 130 at a position opposite to the side pressure assembly 300, the internal thread of the internal threaded barrel 410 is connected to the threaded rod 430, and the first spring seat 310 is fixed to the lower end of the threaded rod 430; the knob 420 is fixed to the internal threaded barrel 410, and the internal threaded barrel 410 is manually driven to rotate, so that the threaded rod 430 drives the side pressure assembly 300 to rise and fall, thereby adjusting the height of the side pressure assembly 300, so that when the pressing plate 600 is in a pressed state and the side pressure assembly 300 is in a state where the elastic force is not released, the second spring seat 340 is infinitely close to the upper surface of the pressing plate 600, so that the pressure provided by the side pressure assembly 300 tends to be maximized.

[0051] Preferably, a limit head 440 is fixed to the upper end of the threaded rod 430 to limit excessive downward movement of the threaded rod 430, and a hexagonal limit shaft 450 is inserted into the threaded rod 430 from the upper end of the threaded rod 430 to limit the rotation of the threaded rod 430, and the upper end of the hexagonal limit shaft 450 is fixed on the top plate 130 to lock the position of the hexagonal limit shaft 450.

[0052] When in use (when working), first determine the height of the side pressure assembly 300. During specific operation, place the nano heat insulation board to be pressed on the upper surface of the base 110, and control the compression cylinder 200 to extend until the pressing plate 600 reaches the nano heat insulation board to be pressed. At this time, rotate the knob 420 to make the threaded rod 430 drive the side pressure assembly 300 to rise and fall, thereby adjusting the height of the side pressure assembly 300 until the bottom surface of the wedge block 700 is almost flush with the upper surface of the pressing plate 600. At this time, the adjustment is completed.

[0053] After the adjustment is completed, it reaches the pressing stage. During pressing, the compression cylinder 200 is controlled to extend. At this time, the pressure seat 500 and the pressing plate 600 are synchronously lowered, and the side pressure assembly 300 passes through the through hole 610 relatively until the pressing plate 600 reaches the upper surface of the nano thermal insulation board. As the compression cylinder 200 continues to extend, the pressure seat 500 begins to squeeze the compression spring 810 and continues to move downward. During its downward movement, the thrust block 530 applies pressure to the wedge block 700, so that the wedge block 700 can be in the water. The wedge block 700 is subjected to forces in both horizontal and vertical directions. The vertical force applied to the wedge block 700 is used to squeeze the pressing plate 600. The horizontal force applied to the wedge block 700 is used to move the wedge block 700 outward on the upper surface of the pressing plate 600 (and squeeze the third spring 630 to deform) to expand the pressure range on the pressing plate 600 until the wedge block 700 drives the push plate 900 to contact the force plate 361 (the force plate 361 is fixed to the end of the tooth column 360 away from the second spring seat 340). At this time, Fig.14 When the gear 392 is in the state shown in the figure, the compression cylinder 200 continues to extend, the pressure seat 500 continues to move downward, and the wedge block 1 700 continues to move downward, so that the push plate 900 pushes the force plate 361, so that the tooth column 360 can drive the active gear 393 to rotate, thereby realizing the rotation of the acceleration gear 392. When the acceleration gear 392 rotates, it can drive the driven gear 391 to rotate, and then realize the rotation of the rotating disk 370. When the rotating disk 370 rotates, the protrusion 371 can push the wedge block 2 350, so that the wedge block 2 350 can move radially along the second spring seat 340, forming a state of the side pressure assembly 300 being opened. When the wedge block 2 350 moves radially along the second spring seat 340, the ball head 321 can enter the inclined limiting groove 352 from the straight portion 354 to release the elasticity of the pressure spring 330. At this point, the downward pressing operation of the side pressure assembly 300 is completed, forming Fig.15 Status shown.

[0054] After the pressing is completed, the compression cylinder 200 is shortened. At this time, the pressure seat 500 first moves upward, causing the pressing plate 600 to move upward, and the third spring 630 is reset, so that the wedge block 1 700 and the push plate 900 are reset. At this time, the tooth column 360 loses pressure, and the second spring 380 is reset, so that most of the wedge block 2 350 returns to the second spring seat 340, and the ball head 321 re-enters the straight limiting groove 355 from the inclined limiting groove 352, thereby limiting the distance between the first spring seat 310 and the second spring seat 340, so that the pressure spring 330 is in the energy storage state again, and in this state, as the pressure seat 500 rises, the pressing plate 600 also begins to rise, so that the side pressure assembly 300 can pass through the through hole 610 at this time.
