DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0030] In order to facilitate the understanding of the technical solution of the utility model, the technical problems existing in the prior art are further explained here:

[0031] When isostatic pressing is performed on sheet materials, if the working medium is a liquid, such as water, the material needs to be packaged in a vacuum bag first to prevent the material from getting wet. However, after the isostatic pressing, the two adjacent bags stick to each other, and after being wetted, the two bags are not easy to separate due to the surface tension of the water. If they are directly placed in an oven for drying, the water between the bags is not easy to evaporate. At present, the above methods usually use manual separation and drying or manual wiping, which is time-consuming and labor-intensive, resulting in low processing efficiency.

[0032] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides an isostatic press 100 , including a cylinder body 110 , a cover body 120 , a material rack 130 and a pressurizing mechanism 140 .

[0033] The cylinder 110 has a processing chamber 111 , the cover 120 is movably arranged relative to the cylinder 110 , and the cover 120 can pass through the sealing position during movement, and the material rack 130 is used to place materials. The pressurizing mechanism 140 is connected to the cylinder 110 and is used to pressurize the pressurized medium in the processing chamber 111 .

[0034] When the cover 120 moves to the sealing position, the cover 120 seals the processing chamber 111 , and the material rack 130 is located in the processing chamber 111 , and the pressurized medium in the processing chamber 111 performs isostatic pressure treatment on the material.

[0035] Furthermore, the isostatic press further comprises a drying mechanism 150, which is disposed outside the cylinder body 110. The material rack 130 is provided with a plurality of placement slots 131 arranged at intervals, and each placement slot 131 is used to place a material so that the materials are spaced apart.

[0036] The cover 120 can also pass through the drying position during the movement. When the cover 120 moves to the drying position, the material rack 130 is located outside the cylinder 110 and corresponds to the drying mechanism 150, so that the drying mechanism 150 can dry the materials on the material rack 130.

[0037] It should be noted that, in this embodiment, the material is a product wrapped in a packaging bag, and the product can be in the form of a sheet or a block. In addition, the pressurized medium is a liquid, and specifically water or oil.

[0038] By using the above-mentioned isostatic press, multiple materials are placed in multiple placement slots 131 respectively, and then the cover 120 is placed in a sealed position, and the pressurized medium in the processing chamber 111 is pressurized by the pressurizing mechanism 140, so as to perform isostatic pressing on the materials on the material rack 130. After the processing is completed, the cover 120 is moved to the drying position, and the multiple materials are dried by the drying mechanism 150. Since the materials on the material rack 130 are arranged at intervals, the drying mechanism 150 can quickly dry the materials, thereby effectively improving the drying efficiency, and then improving the processing efficiency.

[0039] It should be further explained that, in other embodiments, in order to improve processing efficiency, the isostatic press can also be applied to the processing of products of other shapes. Of course, it is preferred to process sheet products and sheet materials.

[0040] In one embodiment, the cylinder body 110 is further provided with an opening communicating with the processing chamber 111, and when the cover body 120 moves to the sealing position, the cover body 120 can seal the opening, thereby sealing the processing chamber 111. Furthermore, the opening is located at the top of the cylinder body 110, and the cover body 120 can be raised and lowered relative to the cylinder body 110, thereby sealing the opening during the descent process.

[0041] It is understandable that when the cover 120 rises to the drying position, the cover 120 and the material rack 130 are both located above the opening to ensure that the pressurized medium remaining on the cover 120 , the material rack 130 and the material flows back into the processing chamber 111 .

[0042] In one embodiment, the isostatic press further includes a driving mechanism connected to the cover 120 to drive the cover 120 to rise and fall in the vertical direction, thereby enabling the cover 120 to move relative to the cylinder 110. The driving mechanism is a conventional mechanism and will not be described in detail herein.

[0043] In one embodiment, the isostatic press further includes a control mechanism 160, which is disposed outside the cylinder body 110 and is electrically connected to the driving mechanism, the pressurizing mechanism 140 and the drying mechanism 150 to realize the automated operation of the isostatic press.

[0044] For example, after placing a plurality of materials on the material rack 130, the control mechanism 160 first controls the driving mechanism to drive the cover 120 to descend to the sealing position, and then controls the pressurizing mechanism 140 to pressurize the processing chamber 111 to perform isostatic pressing on the materials. After the processing is completed, the control mechanism 160 controls the driving mechanism to drive the cover 120 to ascend to the drying position, and then controls the drying mechanism 150 to dry the materials on the material rack 130.

[0045] In one embodiment, the material rack 130 includes a connecting member 132 and a supporting member 133, wherein the connecting member 132 is connected to the cover 120, and the supporting member 133 is connected to the connecting member 132, and a plurality of placement grooves 131 are provided on the supporting member 133. Specifically, the connecting member 132 is connected to the bottom of the cover 120 to ensure that the supporting member 133 is located in the processing chamber 111 after the cover 120 seals the opening.

[0046] In one embodiment, the connecting member 132 includes a first connecting plate 1321 and a second connecting plate 1322. The first connecting plate 1321 and the second connecting plate 1322 are both connected to the cover body 120 and are arranged at intervals. The two ends of the supporting member 133 in the length direction are respectively connected to the first connecting plate 1321 and the second connecting plate 1322, and a plurality of placement grooves 131 are arranged at intervals along the length direction of the supporting member 133.

[0047] Furthermore, the connecting member 132 further includes a fixing plate 1323, which is connected to the first connecting plate 1321 and the second connecting plate 1322, so as to fix the first connecting plate 1321 and the second connecting plate 1322, thereby improving the stability of the structure of the material rack 130. Specifically, the fixing plate 1323 is connected to one end of the first connecting plate 1321 and the second connecting plate 1322 away from the cover body 120, and the fixing plate 1323, the first connecting plate 1321, the second connecting plate 1322 and the cover body 120 enclose a bearing space, and the bearing member 133 is located in the bearing space.

[0048] In one embodiment, the carrier 133 includes a carrier plate 1331 and a plurality of first partitions 1332. The carrier plate 1331 is connected to the connecting member 132, and the two ends of the carrier plate 1331 in the length direction are respectively connected to the first connecting plate 1321 and the second connecting plate 1322. The plurality of first partitions 1332 are arranged at intervals on the same side of the carrier plate 1331 along the length direction of the carrier plate 1331, and any two adjacent first partitions 1332 and the carrier plate 1331 are enclosed to form the above-mentioned placement groove 131, so that two adjacent placement grooves 131 are separated by the first partitions 1332.

[0049] In another embodiment, the carrier 133 includes a carrier plate 1331, a cover plate 1333, a plurality of first partition plates 1332, and a plurality of second partition plates 1334. The carrier plate 1331 and the cover plate 1333 are both connected to the connector 132, and the carrier plate 1331 and the cover plate 1333 are arranged in parallel, and the cover plate 1333 and the carrier plate 1331 correspond to each other to enclose and form a placement space.

[0050] A plurality of first partitions 1332 are arranged on a side of the supporting plate 1331 facing the cover plate 1333 and are spaced apart along the length direction of the supporting plate 1331. A plurality of second partitions 1334 are arranged on a side of the cover plate 1333 facing the supporting plate 1331 and the plurality of second partitions 1334 correspond one-to-one to the plurality of first partitions 1332 so as to divide the placement space into a plurality of placement grooves 131 spaced apart along the length direction of the supporting plate 1331.

[0051] In practical applications, the carrying plate 1331 is located below the cover plate 1333. In this way, after the material is placed in the placement slot 131, the bottom of the material is located between two adjacent first partitions 1332, and the top of the material is located between two adjacent second partitions 1334, so as to avoid contact between the materials in two adjacent placement slots 131.

[0052] Specific to Figure 2 In the embodiment shown, there is a gap between the first partition 1332 and the second partition 1334, so the two adjacent placement grooves 131 are connected to each other. Of course, in other embodiments, the first partition 1332 and the second partition 1334 can also be connected as a whole, and in this case, the two adjacent placement grooves 131 are in a partitioned state. In addition, the two ends of the load-bearing plate 1331 and the cover plate 1333 in the length direction are connected to the first connecting plate 1321 and the second connecting plate 1322, so the first partition 1332 and the second partition 1334 at the two ends can also be enclosed with the first connecting plate 1321 or the second connecting plate 1322 to form the placement groove 131.

[0053] In combination with the above embodiment, it should be explained that, since the material rack 130 is placed in the processing chamber 111 for isostatic pressing, the structural strength of the material rack 130 needs to be able to remain unchanged under a pressure of 40Mpa-45Mpa.

[0054] In one embodiment, the drying mechanism 150 includes a mounting seat 151 and a heating element 152. The mounting seat 151 is arranged on the outside of the cylinder body 110, and the heating element 152 is arranged on the mounting seat 151 and can correspond to the material rack 130. That is, after the cover body 120 moves to the drying position, the heating element 152 corresponds to the material rack 130, thereby drying the material on the material rack 130.

[0055] Furthermore, the drying mechanism 150 further includes a fan 153, which is disposed on the mounting seat 151 and can blow air toward the rack 130, that is, after the cover 120 moves to the drying position, the fan 153 can blow air toward the rack 130, and the heating element 152 is located on the airflow path generated by the fan 153, thereby achieving hot air blowing toward the rack 130, further improving the drying speed. Specifically, the hot air temperature is greater than 50°C, preferably 60°C.

[0056] It can be understood that the heating element 152 is a heating wire. When only the heating element 152 is provided, the heat generated by the heating element 152 is directly used to dry the material; when the fan 153 and the heating element 152 are provided, the airflow generated by the fan 153 passes through the heating element 152 and then blows toward the material on the material rack 130. In addition, after the cover 120 is moved to the drying position, the multiple materials can be arranged at intervals along the airflow direction, or the multiple materials can all face the airflow direction, so that the hot air passes through the gaps between the materials, further improving the drying efficiency.

[0057] In order to facilitate the understanding of the technical solution of the utility model, Figure 1 The action flow of the isostatic press in the above embodiment is described as follows:

[0058] First, multiple materials are placed in multiple placement slots 131 respectively, and then the driving mechanism drives the cover 120 to descend to the sealing position. Next, the pressurizing mechanism 140 pressurizes the pressurized medium in the processing chamber 111, thereby performing isostatic pressure treatment on the materials in the processing chamber 111. After the treatment is completed, the driving mechanism drives the cover 120 to rise to the drying position, and then the drying mechanism 150 blows hot air toward the materials on the material rack 130.

[0059] It should be noted that, after actual testing, taking the processing of sheet products with a size of 15cm*15cm*0.3cm as an example, when the processing method of manual separation and drying is adopted, the processing speed is 650 sheets per hour; when the processing method of manual wiping is adopted, the processing speed is 400 sheets per hour; after the isostatic press in the above embodiment is adopted, 850 sheets can be processed per hour, which greatly improves the processing efficiency. In addition, the pressurizing mechanism 140 and the control mechanism 160 in the above embodiment are also conventional mechanisms, which will not be described in detail here.

[0060] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
