Description

Technical Field

[0001] The invention relates to the technical field of storage devices, and more particularly to a polyurethane elastomer safety storage device. Background Art

[0002] The proper storage of polyurethane elastomers is not only the key to maintaining their excellent physical properties and extending their service life, but also a delicate and crucial project, which requires impeccable control of every subtle condition of the storage environment - from subtle temperature regulation to precise management of humidity to strict light shielding. This series of complex and precise requirements is aimed at creating a microenvironment that is most suitable for the preservation of polyurethane elastomers to ensure that their quality is not damaged during a long storage period.

[0003] Chinese patent document (CN108839907B) discloses a safe storage device for polyurethane elastomers, which states in the specification that "it includes a support body, a storage body, a compacting body and a baffle assembly. The present invention can shake the polyurethane elastomer particles to make the polyurethane elastomer particles evenly distributed and then compact and store the polyurethane elastomer particles, so that the polyurethane elastomer particles have no movement space, thereby reducing the damage to the polyurethane elastomer caused by vibration during automobile transportation. The storage body is slidably connected to the support body, the upper end of the compacting body is slidably connected to the support body, the lower end of the compacting body is slidably connected to the storage body, and two baffle assemblies are arranged in front and behind. The two baffle assemblies are fixedly connected to the front and rear ends of the storage body respectively, and the compacting body and the two baffle assemblies are slidably matched." However, in actual use, although the gap between the polyurethane elastomers is reduced and the polyurethane elastomers are fixed by extrusion, mechanical damage to the polyurethane elastomers will still be caused. Excessive extrusion of the polyurethane elastomer will affect its performance, thereby causing damage to the polyurethane elastomer.

[0004] However, many polyurethane elastomer storage devices on the market can effectively isolate adverse external factors and ensure the safety of materials, but they are often too large to be used in the logistics and transportation process, increasing transportation costs and operating difficulties. In addition, these large devices are not flexible enough to deal with sudden changes in the storage environment, especially in quickly adjusting the internal temperature, and are difficult to meet certain emergency or special storage needs.

[0005] On the other hand, storage solutions that pursue lightness and portability, such as simple packaging bags with vacuum packaging, have advantages in reducing weight and being easy to carry, but their protective performance has become a major shortcoming. During transportation, these lightweight packages are easily damaged by external impact and extrusion, which in turn causes leakage or contamination of the contents, seriously threatening the quality and storage safety of polyurethane elastomers. In view of this, we propose a safe storage device for polyurethane elastomers. Summary of the invention

[0031] A method for using a polyurethane elastomer safety storage device comprises the following steps:

[0032] S1. When in use, open the cover and put the polyurethane elastomers to be stored into the storage box in sequence. Stop putting the polyurethane elastomers in when the polyurethane elastomers occupy 80% to 90% of the internal height of the storage box. At this time, close the cover and connect the installation assembly through the external vacuum extraction device to extract the air inside the storage box.

[0033] S2. When the external vacuum extraction device is connected to the installation component, the external vacuum extraction device will enter the installation component and squeeze the connecting component downward. When the connecting component moves down to the bottom of the cover plate, the external vacuum extraction device will be connected to the storage box through the connecting component. At this time, slightly turn the external vacuum extraction device so that it can be inserted into the installation component to operate and extract the air in the storage box. As the external vacuum extraction device operates, a large amount of air is discharged. At this time, because the storage box is under negative pressure and the piston plate is under normal pressure, the piston plate may gradually move up. When the polyurethane elastomer is about to contact the cover plate or the sealing component through the observation window, turn the knob counterclockwise to fix the joint to the docking shell to position the gear and the slide rod. At this time, the piston plate stops moving, and during the movement of the piston plate, it will push the adjustment component to adjust the heat conductive component accordingly, causing the heat conductive component to deform. When the storage box is in a vacuum state, turn off the external vacuum device and take it out. The sealing component will seal the connecting component, and the device can be carried at this time.

[0034] S2.1. When the external vacuum extraction device is inserted into the mounting ring, it is necessary to ensure that the external vacuum extraction device is inserted into the slide groove, and rotate the external vacuum extraction device after it is completely inserted into the mounting ring, so that it is fixed through the slot below the slide groove, and in the process of the external vacuum extraction device entering the mounting ring, it will contact with the extrusion ring and squeeze it to move downward. At this time, the slide moves down to the bottom of the cover plate and is connected to the space below the cover plate through the air inlet hole. At this time, the vacuum treatment can be carried out, and after the vacuum treatment is completed, it is only necessary to separate the external vacuum extraction device from the mounting ring and pull it out. Because the second spring will continue to push the slide upward through the sealing plate when pulling it out, the air inlet outside the slide contacts the inner wall of the mounting ring, and after the second spring is reset, the sealing plate will seal the bottom of the mounting ring;

[0035] S2.2. When the initial vacuum is drawn and the piston plate moves up due to negative pressure, the piston plate will drive the first telescopic sleeve to contract, so that the air inside the first telescopic sleeve quickly enters the second telescopic sleeve along the conduit. At this time, the second telescopic sleeve will extend. With the extension of the second telescopic sleeve, the first heat conducting plate will move forward. At this time, several second heat conducting plates will be deflected along the rotator and the contact piece inside the movable groove due to being stuck in the movable groove, so that they are in a vertical state with the first heat conducting plate. After moving to a suitable height on the piston plate, the knob can be turned counterclockwise, so that the docking shell can be fixed through the docking joint, so that the gear cannot rotate. At this time, the gear will be fixed through the tooth groove and the sliding rod to ensure that the piston plate is in a positioned state.

[0036] Compared with the prior art, the present invention has the following beneficial effects:

[0037] 1. The present invention designs a heat-conducting component, a connecting component and a sealing component so that the device can control the humidity of the storage environment of the polyurethane elastomer by means of rapid vacuuming, and during transportation, it is only necessary to adjust the temperature of the transportation space. Due to the setting of the heat-conducting component, the device can conduct temperature more quickly to achieve control of the temperature of the storage space of the polyurethane elastomer. On the one hand, the storage box and the cover plate can better protect the polyurethane elastomer to avoid scratches, and the piston plate can reduce the direct squeezing of the polyurethane elastomer by the device, thereby ensuring the safe storage of the polyurethane elastomer. On the other hand, the cooperation of the heat-conducting component and the connecting component can further control the environment for storing the polyurethane elastomer and ensure the quality of the transported polyurethane elastomer.

[0038] 2. The present invention also designs the installation component, the connecting component and the sealing component. When the external vacuum extraction device is inserted into the installation ring, it is necessary to ensure that the external vacuum extraction device is inserted into the slide groove, and the external vacuum extraction device is rotated after it is completely inserted into the installation ring, so that it is fixed through the card groove below the slide groove, and in the process of the external vacuum extraction device entering the installation ring, it will contact with the extrusion ring and squeeze it to move downward. At this time, the slide moves down to the bottom of the cover plate and is connected with the space below the cover plate through the air inlet hole. At this time, the vacuum treatment can be carried out, and after the vacuum treatment is completed, it is only necessary to separate the external vacuum extraction device from the installation ring and pull it out. Because the second spring is pulled out when it is pulled out The spring will continue to push the slide cylinder upward through the sealing plate, so that the air inlet outside the slide cylinder contacts the inner wall of the mounting ring and after the second spring is reset, the sealing plate will seal the bottom of the mounting ring, so that the device can quickly complete the connection between the device and the external vacuum device, and after use, only the external vacuum device needs to be removed. On the one hand, the efficiency of vacuuming the inside of the device can be accelerated, and on the other hand, after the vacuuming is completed, the device can automatically seal the mounting ring and the air inlet above it to prevent the outside air from entering and causing the polyurethane elastomer to contact other gases, thereby ensuring the safety of the device when used.

[0039] 3. The present invention also designs a heat-conducting component and an adjusting component. When the piston plate moves upward due to negative pressure during the initial vacuuming, the piston plate will drive the first telescopic sleeve to contract, so that the air inside the first telescopic sleeve quickly enters the second telescopic sleeve along the conduit. At this time, the second telescopic sleeve will be extended. With the extension of the second telescopic sleeve, the first heat-conducting plate will move forward. At this time, several second heat-conducting plates will be deflected along the rotator and the contact sheet inside the active groove due to being stuck in the active groove, so as to be in a vertical state with the first heat-conducting plate, and after moving to a suitable height on the piston plate, they can be rotated counterclockwise. By turning the knob, the docking shell can be fixed through the docking joint so that the gear cannot rotate. At this time, the gear will be fixed through the tooth groove and the sliding rod to ensure that the piston plate is in a positioned state. Since the first heat conduction plate is popped out, when it is necessary to control the internal temperature of the device, it is only necessary to adjust the temperature of the transportation space. The first heat conduction plate will adjust the temperature in the storage box accordingly through the second heat conduction plate and the third heat conduction plate, thereby reducing the difficulty of adjusting the internal temperature of the device. At the same time, after the first heat conduction plate is reset, the storage boxes on both sides can be protected, thereby improving the protection effect of the device on the polyurethane elastomer.

The upper and lower parts of the inner wall of the positioning frame 3042 are both clamped with a rotator 3043, which is composed of a bearing and a rotating shaft. The positioning frame 3042 is rotatably connected to the second heat conducting plate 3044 through the rotator 3043. The other side of the first heat conducting plate 3041 is fixedly connected to a plurality of third heat conducting plates 3045.

The plurality of third heat conducting plates 3045 are fixedly connected to the second telescopic sleeve 3033. One side of the inner wall of the mounting groove 1015 is overlapped, and when the cover 201 needs to be opened, it is only necessary to squeeze the sealing plate 2063 downwards, so that the outside air can quickly enter the storage box 1011 along the air inlet 2032 outside the slide 2031, so that the air pressure inside the storage box 1011 is the same as that of the outside. At this time, the cover 201 can be opened and the polyurethane elastomer stored inside can be taken out, thereby reducing the difficulty of opening the cover 201, reducing the use of too many complex devices, reducing the weight of the device, and improving the efficiency of carrying the device.

[0067] Working principle: This embodiment provides a polyurethane elastomer safe storage device. When in use, the cover plate 201 is opened and the polyurethane elastomers to be stored are sequentially put into the storage box 1011. When the polyurethane elastomers occupy 80% to 90% of the internal height of the storage box 1011, the polyurethane elastomers are stopped from being put in. At this time, the cover plate 201 is closed and the installation component 202 can be connected to extract the air inside the storage box 1011 through the external vacuum extraction device;

[0068] When the external vacuum extraction device is connected to the installation component 202, the external vacuum extraction device will enter the installation component 202, and at the same time, it will squeeze the connecting component 203 downward. When the connecting component 203 moves down to under the cover plate 201, the external vacuum extraction device will be connected to the storage box 1011 through the connecting component 203. At this time, slightly turn the external vacuum extraction device so that it is stuck in the installation component 202 to operate and extract the air in the storage box 1011. As the external vacuum extraction device runs, a large amount of air is discharged. At this time, because the storage box 1011 is under negative pressure above and normal pressure below the piston plate 301, the piston plate 301 may gradually move upward, and the connecting component 203 may gradually move upward. When the polyurethane elastomer is about to contact the cover plate 201 or the sealing component 206 through the observation window 102, the knob 1045 is turned counterclockwise to fix the docking shell 1039 through the docking joint 1044 so as to position the gear 1036 and the slide rod 1034. At this time, the piston plate 301 stops moving, and during the movement of the piston plate 301, the adjustment component 303 is pushed to adjust the heat conducting component 304 accordingly, so that the heat conducting component 304 is deformed. When the storage box 1011 is in a vacuum state, the external vacuum device is turned off and taken out, and the sealing component 206 seals the connecting component 203. At this time, the device can be carried;

[0069] When the external vacuum extraction device is inserted into the mounting ring 2021, it is necessary to ensure that the external vacuum extraction device is inserted into the slide groove 2022, and after it is completely inserted into the mounting ring 2021, the external vacuum extraction device is rotated so that it is fixed through the card groove 2023 below the slide groove 2022. In the process of the external vacuum extraction device entering the mounting ring 2021, it will contact with the extrusion ring 2033 and squeeze it to move downward. At this time, the slide cylinder 2031 moves down to the bottom of the cover plate 201 and will pass through the air inlet hole 2032 and contact with the The space below the cover plate 201 is connected, and vacuuming can be performed at this time. After vacuuming is completed, the external vacuum extraction device only needs to be separated from the mounting ring 2021 and pulled out. When pulling out, the second spring 2062 will continue to push the slide 2031 upward through the sealing plate 2063, so that the air inlet 2032 outside the slide 2031 contacts the inner wall of the mounting ring 2021. After the second spring 2062 is reset, the sealing plate 2063 will seal the bottom of the mounting ring 2021.

[0070] When the piston plate 301 moves upward due to negative pressure during the initial vacuuming, the piston plate 301 will drive the first telescopic sleeve 302 to contract, so that the air inside the first telescopic sleeve 302 quickly enters the second telescopic sleeve 3033 along the conduit 3031. At this time, the second telescopic sleeve 3033 will extend. With the extension of the second telescopic sleeve 3033, the first heat conducting plate 3041 will move forward. At this time, several second heat conducting plates 3044 will be stuck in the movable groove 1013. It is deflected along the rotator 3043 and the contact piece inside the movable groove 1013, so that it is in a vertical state with the first heat conduction plate 3041, and after moving to a suitable height on the piston plate 301, the knob 1045 can be turned counterclockwise, so that the docking shell 1039 is fixed through the docking joint 1044, so that the gear 1036 cannot rotate. At this time, the gear 1036 will be fixed to the slide rod 1034 through the tooth groove 1035 to ensure that the piston plate 301 is in a positioned state.
