Description

Technical Field

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

[0002] The pore size of nanoporous super insulation material is smaller than the average molecular free path of air (≤70nm) and has a very low volume density. The material has a lower insulation coefficient than air at room temperature and set temperature. With the continuous deepening of insulation material research, while maintaining the original thermal properties of the material, the research on nanoporous insulation materials is also constantly developing in the direction of practicality and engineering. This product uses nanoporous materials to solve the problem of convective heat transfer and minimize convective heat transfer. The thermal conductivity coefficient is controlled to the limit according to the minimum material particle size and then the binder is added. At present, when producing nano insulation boards, multiple nano sheets need to be bonded and pressed.

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 17 The present invention describes a compression device for producing a nano thermal insulation board provided by an embodiment of the present invention.

[0023] See also Figure 1-Figure 5 An embodiment of the present invention provides a compression device for producing nano thermal insulation boards, including a compression platform 101, a main compression cylinder 3, a side pressure plate 2 and an auxiliary compression cylinder 4.

[0024] A compression plate 9 is provided above the compression platform 101. When the compression plate 9 descends, the nano-insulation plate on the upper surface of the compression platform 101 can be compressed. The main compression cylinder 3 is located above the compression plate 9, located in the middle above the compression plate 9. The main compression cylinder 3 extends and contracts to drive the compression plate 9 to descend or ascend. The side pressure plate 2 is located in the corner area of ​​the upper surface of the compression plate 9. The side pressure plate 2 moves downward to press down the corners of the compression plate 9. The auxiliary compression cylinder 4 is located on the outer side of the compression platform 101 near the four vertical edges. The auxiliary compression cylinder 4 contracts and extends to drive the side pressure plate 2 to move downward or upward, so that the side pressure plate 2 can press down the corners of the compression plate 9 when moving downward, thereby increasing the pressure provided by the compression plate 9 to the edge area of ​​the workpiece below when pressing down.

[0025] Combination Figure 1-3 As shown, the above-mentioned master compression cylinder 3 includes a master cylinder body 31, a master piston 37 arranged in the master cylinder body 31, and a master compression rod 32 inserted into the master cylinder body 31 from the lower end of the master cylinder body 31 and fixedly connected to the master piston 37. The master piston 37 divides the master cylinder body 31 into a master rodless chamber 35 and a master rod chamber 36. The master cylinder body 31 is provided with a master rodless air port 33 connected to the master rodless chamber 35, and the master cylinder body 31 is provided with a master rod air port 34 connected to the main rod chamber 36. When air is taken into the main rodless air port 33, the main piston 37 can be pushed downward, so that the main piston 37 can move downward, and push the main compression rod 32 to move downward, thereby driving the compression plate 9 to move downward. At the same time, when the main piston 37 moves downward, the gas in the main rod chamber 36 is discharged through the main rod air port 34.

[0026] The above-mentioned auxiliary compression cylinder 4 includes an auxiliary cylinder body 41, an auxiliary piston 47 arranged in the auxiliary cylinder body 41, and an auxiliary rod body 42 inserted into the auxiliary cylinder body 41 from the upper end of the auxiliary cylinder body 41 and fixedly connected to the auxiliary piston 47. The auxiliary piston 47 divides the auxiliary cylinder body 41 into an auxiliary rod chamber 45 and an auxiliary rodless chamber 46. The upper end of the auxiliary rod body 42 is fixedly connected to the opposite side pressure plate 2. The auxiliary cylinder body 41 is provided with an auxiliary rod air port 43 connected to the auxiliary rod chamber 45, and the auxiliary cylinder body 41 is provided with an auxiliary rodless air port 44 connected to the auxiliary rodless chamber 46. When the auxiliary rod air port 43 takes in air, it can push the auxiliary piston 47 downward to move the auxiliary rod body 42 downward. The auxiliary rod body 42 can pull the side pressure plate 2 downward, so that the side pressure plate 2 can provide downward pressure to the edge area of ​​the compression plate 9.

[0027] The auxiliary compression cylinder 4 and the main compression cylinder 3 can be independent air supply systems or a total air supply system; when the two are independent air supply systems, the auxiliary compression cylinder 4 and the main compression cylinder 3 work independently, which is the existing technology, so it will not be elaborated here.

[0028] like Figure 2 and Figure 3 As shown, when it is a total air supply system, the air capacity of one main cylinder 31 is equal to the air capacity of four auxiliary cylinders 41. The total air supply system should include a reversing valve group and an air supply source.

[0029] In order to achieve the purpose of all cylinders sharing one gas source, the auxiliary rod air port 43 is responsible for not only air intake but also air exhaust, and the auxiliary rodless air port 44 is also responsible for air intake and exhaust. Therefore, a three-way pipe one is assembled on the auxiliary rod air port 43, and the other two ends of the three-way pipe one are respectively the first exhaust head 431 and the first intake head 432; a three-way pipe two is assembled on the auxiliary rodless air port 44, and the other two ends of the three-way pipe two are respectively the second exhaust head 441 and the second intake head 442.

[0030] The reversing valve group is connected to the main rodless chamber 35, the main rod chamber 36, the three-way pipe 1 and the three-way pipe 2 through a pipe system. The reversing valve group is used to allow air to enter the main rodless chamber 35 and the gas in the main rod chamber 36 enters the auxiliary rod chamber 45 when the main compression rod 32 moves downward, forming a state in which the auxiliary rod body 42 pulls the side pressure plate 2 downward, and the reversing valve group is used to allow air to enter the main rod chamber 36 and the gas in the main rodless chamber 35 enters the auxiliary rodless chamber 46 when the main compression rod 32 moves upward, forming a state in which the auxiliary rod body 42 pushes the side pressure plate 2 upward, thereby achieving the purpose of synchronously driving the compression plate 9 to move by the main compression rod 32 and the auxiliary rod body 42.

[0031] The reversing of the reversing valve group here can be powered by electromagnetic, hydraulic or mechanical power.

[0032] Continue to refer to Figure 3 and Figure 4 The above-mentioned reversing valve group includes a main cylinder valve 14, an auxiliary cylinder valve 15 and an exhaust valve 16.

The second transverse guide rod 13 is inserted into the second transverse guide hole 721, and the second slide 72 can slide on the second transverse guide rod 13. The two ends of the second transverse guide rod 13 are fixed with a reduced diameter portion 131 through a connecting portion 132. The diameter of the reduced diameter portion 131 is smaller than the diameter of the second transverse guide rod 13. When the second slide 72 moves to the reduced diameter portion 131, the force spring 73 can push the second slide 72 downward, so that the second slide 72 is pressed against the upper surface of the side pressure plate 2 to provide additional pressure to the side pressure plate 2.

[0042] Preferably, a clearance groove 21 is provided in the area of ​​the side pressure plate 2 opposite to the first transverse guide rod 12 , so that the side pressure plate 2 is not blocked by the first transverse guide rod 12 when moving up and down.

[0043] Reference Figure 5-Figure 7 as well as Figure 15-17As shown, in order to realize that during the descent of the compression plate 9, the assembly seat 81 can automatically push the push rod 8, so as to realize the purpose of automatically moving the elastic downward pressure component 7 to the upper surface of the side pressure plate 2, the compression device for producing the nano heat insulation board provided in the embodiment of the present invention also includes a driving shaft 6, which is located on the side of the connecting plate 22 away from the compression plate 9, and the driving shaft 6 is rotatably installed between the base 102 and the top frame 104 through a bearing, and a first vertical groove 61 is axially provided on the upper part of the driving shaft 6 close to the side of the connecting plate 22, and a slider 23 adapted to the first vertical groove 61 is fixed on the connecting plate 22, and a second vertical groove 63 is axially provided on the side of the lower part of the driving shaft 6 away from the connecting plate 22, and the second vertical groove 63 is connected to the first vertical groove 61 by a spiral groove 62, and a convex portion 64 is fixedly provided on the side of the driving shaft 6 close to the second vertical groove 63 at the same height as the assembly seat 81; In this embodiment, when the compression plate 9 and the side pressure plate 2 move downward, the side pressure plate 2 can drive the slider 23 to first move in the first vertical groove 61, and then pass through the spiral groove 62. When it passes through the spiral groove 62, it can drive the drive shaft 6 to rotate 180°, so that the convex portion 64 at this time can push the assembly seat 81, and the assembly seat 81 can push the push rod 8, thereby achieving the purpose of automatically moving to the upper surface of the side pressure plate 2.

[0044] Preferably, the first transverse guide rod 12 and the reduced diameter portion 131 are both suspended on the lower surface of the side frame 103 through the first hanger 5, and a second spring 10 is provided between the first hanger 5 and the first slide seat 71, so that the first slide seat 71 is automatically pushed after the collecting seat 81 loses the pressure of the protrusion 64, so that the elastic downward pressure component 7 returns to the state of being detached from the side pressure plate 2.

[0045] Preferably, a spring telescopic rod 82 is installed on the side of the assembly seat 81 close to the compression plate 9, and the spring telescopic rod 82 is suspended on the lower surface of the side frame 103 through the second hanger 83. The spring telescopic rod 82 is used to limit the moving direction of the assembly seat 81 when it is pushed by the protrusion 64, ensuring that the assembly seat 81 can only move horizontally, thereby achieving the same distance for the two push rods 8 to push the first slide seat 71.

[0046] The spring telescopic rod 82 mentioned here is a common sleeve-type telescopic rod in the prior art, and the two sets of inserted rods are connected by springs.

[0047] Preferably, the height difference between the second transverse guide rod 13 and the reduced diameter portion 131 is greater than the axial height of the spiral groove 62, so that after the slider 23 passes through the spiral groove 62, the upper surface of the reduced diameter portion 131 has not reached the top surface of the second transverse guide hole 721, so that the force of the force spring 73 can be transmitted to the upper surface of the side pressure plate 2 only through the second slide seat 72 (not transmitted to the reduced diameter portion 131).

[0048] When in use (when working); 1. Downward compression process of compression plate 9: Figure 8 The nano heat insulation board to be compressed is placed on the upper surface of the compression platform 101, and then the valve cores of the main cylinder valve 14, the auxiliary cylinder valve 15 and the exhaust valve 16 are controlled to form Figure 3 The state shown (the valve core of the main cylinder valve 14 is close to the left side, the valve cores of the auxiliary cylinder valve 15 and the exhaust valve 16 are close to the right side, and the air supply source is sucked in from the air source inlet 141), and reaches the main rodless air port 33 through the main valve input port a144, and enters the main rodless chamber 35, so that the main piston 37 moves downward. When the main piston 37 moves downward, it drives the main compression rod 32 to move downward. At the same time, the gas in the main rod chamber 36 is pressed into the main rod air port 34, and reaches the main valve outlet a142 through the main valve input port b145. The gas discharged from the main valve outlet a142 reaches the auxiliary valve outlet b153 through the auxiliary valve inlet b154, and then enters each first air inlet head 432 through the auxiliary valve outlet b153 (at this time, the first exhaust head 431 is in a closed state. This is because the valve core of the exhaust valve 16 is close to the left side, The gas in the first exhaust head 431 cannot enter the exhaust valve exhaust port a165 from the exhaust valve inlet a162 to be discharged), the gas entering the first air inlet head 432 can enter the auxiliary rod chamber 45 through the auxiliary rod air port 43 to press down the auxiliary piston 47, so that the auxiliary rod body 42 can move downward. At the same time, the downward movement of the auxiliary piston 47 can also compress the gas in the auxiliary rodless chamber 46, so that the gas in the auxiliary rodless chamber 46 enters the exhaust valve inlet b163 through the second exhaust head 441 and is discharged through the exhaust valve inlet b163 (the gas in the auxiliary rodless chamber 46 will not be discharged from the second air inlet head 442, this is because the auxiliary valve outlet a152 connected to the second air inlet head 442 is in a closed state), the above can realize the synchronous downward movement of the compression plate 9 and the side pressure plate 2, and the side pressure plate 2 is used to provide pressure on the edge of the compression plate 9.

[0049] In the process of the compression plate 9 and the side pressure plate 2 moving downward, the side pressure plate 2 can drive the slider 23 to move first in the first vertical groove 61, and then pass through the spiral groove 62. When it passes through the spiral groove 62, it can drive the drive shaft 6 to rotate 180°, so that the convex portion 64 at this time can push the collection seat 81, the collection seat 81 can push the push rod 8, and then the push rod 8 can push the first slide 71. The first slide 71 can slide toward both ends on the first transverse guide rod 12 and compress the second spring 10. At the same time, due to the axial The guide rod 74 can synchronously push the second slide 72 to slide along the second transverse guide rod 13. When the second slide 72 moves to the reduced diameter portion 131, the force spring 73 can push the second slide 72 downward, so that the second slide 72 is pressed against the upper surface of the side pressure plate 2, and additional pressure is provided to the side pressure plate 2. At this time, the compression plate 9 and the side pressure plate 2 continue to move downward a small distance to compress the nano heat insulation board, and the slider 23 moves down a small amount along the second vertical groove 63, and the second slide 72 continues to press against the side pressure plate 2 (such as Fig. 9and Fig.10 ).

[0050] 2. During the upward resetting process of the compression plate 9, when the compression plate 9 needs to be retracted upward after the compression is completed, Figure 3 On the basis shown in the figure, the valve core of the main cylinder valve 14 moves to the right, and the valve cores of the auxiliary cylinder valve 15 and the exhaust valve 16 move to the left, forming Figure 4 In the state shown, the valve core of the main cylinder valve 14 is close to the right side, and the valve cores of the auxiliary cylinder valve 15 and the exhaust valve 16 are close to the left side. The air supply source takes in air from the air source inlet 141 and enters the main rod chamber 36 through the air source inlet 141, the main valve output port b145 and the main rod air port 34. At this time, the gas in the main rod chamber 36 can push the main piston 37 upward, and the main piston 37 can drive the main compression rod 32 to move upward. At the same time, the main piston 37 can compress the air in the main rodless chamber 35, so that the air in the main rodless chamber 35 enters the main rodless air port 33 and reaches the main valve outlet b143 through the main valve output port a144. The gas discharged from the main valve outlet b143 can enter each of the second valves through the auxiliary valve inlet a155 and the exhaust valve exhaust port a165. The second air inlet head 442 causes gas to continuously enter the auxiliary rodless chamber 46 (these gases will not be discharged through the second air exhaust head 441, because the exhaust valve inlet port b163 connected to the second exhaust head 441 is in a closed state), and the gas in the auxiliary rodless chamber 46 can push the auxiliary piston 47 upward, so that the auxiliary piston 47 pushes the auxiliary rod body 42 upward, and the auxiliary rod body 42 drives the side pressure plate 2 to move upward, and at the same time, the auxiliary piston 47 pushes the gas in the auxiliary rod chamber 45 to be discharged through the first exhaust head 431, the exhaust valve inlet port a162 and the exhaust valve exhaust port a165 (in this process, the gas in the auxiliary rod chamber 45 will not enter the first air inlet head 432, because the auxiliary valve outlet port b153 connected to the first air inlet head 432 is in a closed state).

[0051] In this process, the side pressure plate 2 first drives the slider 23 from the lower end of the spiral groove 62 into the interior of the spiral groove 62 and moves along the spiral groove 62, thereby driving the drive shaft 6 to rotate 180° in the opposite direction. When it rotates too far, the convex portion 64 disengages from the assembly seat 81. At this time, the push rod 8 loses the pressure of the assembly seat 81, and the second spring 10 resets at the same time. When it resets, it can push the first slide seat 71, so that the entire elastic downward pressure assembly 7 gradually approaches the center of the first transverse guide rod 12, so that the elastic downward pressure assembly 7 disengages from the side pressure plate 2, and then the side pressure plate 2 and the compression plate 9 continue to move upward, and the slider 23 slides upward in the first vertical groove 61 until it returns to Figure 8 Status shown.
