Description

Technical Field

[0001] This utility model relates to the field of rubber powder storage technology, and specifically to a rubber powder storage sealing device. Background Technology

[0002] Rubber powder is a widely used material made from waste rubber products through recycling processes. During storage, rubber powder is easily affected by external factors such as dust, impurities, and moisture, which can lead to a decline in quality. Sealed packaging can effectively isolate these contaminants and maintain the purity of the rubber powder.

[0003] Chinese Patent Publication No. CN221719413U discloses a rubber powder storage and sealing device, including an outer chamber and an inner chamber inside the outer chamber. A first sealing ring is fixedly installed on the lower outer wall of the inner chamber, fitting against the inner wall of the outer chamber. A first fixing plate is fixedly installed on one side outer wall of the inner chamber. A shell is fixedly installed on the upper outer wall of the outer chamber. A positioning rod is slidably fitted inside the shell, and one end of the positioning rod penetrates the inner wall of the outer chamber. The first fixing plate has positioning holes at equal intervals that fit the end of the positioning rod. A first pressure block is fixedly installed on the outer wall of the positioning rod. The beneficial effect of this utility model is that by allowing the inner chamber to move longitudinally and be positioned within the outer chamber, it solves the problem of the inability to adjust the storage space of the tank, achieving the effect of conveniently adjusting the storage space of the device and improving the practicality of the device.

[0004] In the aforementioned prior art, the setting of inner and outer chambers enables the storage and sealing of rubber powder, and the inner chamber can be controlled to move up and down within the outer chamber to expand the storage space of the tank. However, the degree of lifting of the inner chamber cannot be adjusted in multiple stages. If the amount of rubber powder is insufficient to fill both the inner and outer chambers, the space inside the tank will not be fully utilized. At the same time, an excessively raised inner chamber will occupy too much space. Furthermore, the rubber powder stored inside the tank will come into contact with the interior of the inner chamber, and the weight of the rubber powder will exert pressure on the inner chamber wall, making it difficult for the inner chamber to move up and down within the outer chamber. Utility Model Content

[0005] In view of the above-mentioned technical deficiencies, the purpose of this utility model is to provide a rubber powder storage and sealing device to solve some or all of the problems in the background art.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A rubber powder storage sealing device, comprising:

[0008] Storage silos are used to store rubber powder.

[0009] Support columns are placed on the storage bins to support them;

[0010] Storage structures are arranged on top of storage bins to expand the storage space of the storage bins;

[0011] The storage structure includes an expansion structure for increasing the storage space of the storage compartment, an adjustment structure for adjusting the size of the storage space of the expansion structure, and a limiting structure for restricting the position of the expansion structure.

[0012] A partition structure, located inside the storage chamber, is used to separate the expansion structure from the rubber powder stored inside the storage chamber.

[0013] Preferably, the expansion structure includes:

[0014] An expansion compartment, which is removably installed inside the storage compartment;

[0015] The lifting screw is located on the expansion chamber;

[0017] Preferably, the adjustment structure includes:

[0018] A U-shaped frame is arranged at one end of the support column, and the U-shaped frame is slidably sleeved on the lifting screw.

[0019] Adjust the gear, which is rotated and installed inside the U-shaped frame;

[0020] The threaded hole is located inside the adjusting gear, and the lifting screw is threaded into the threaded hole.

[0021] A limiting component, arranged on the adjusting gear, is used to limit the rotational position of the adjusting gear.

[0022] Preferably, the limiting component includes:

[0023] An annular groove is formed inside the adjusting gear;

[0024] A limiting ring is arranged inside the U-shaped frame, and the limiting ring is rotatably installed in the annular groove.

[0025] Preferably, the adjustment structure further includes:

[0026] The linkage gear ring is rotatably mounted on the storage bin, and the linkage gear ring meshes with the adjusting gear;

[0027] Two retaining rings are fixedly fitted onto the storage compartment. The two retaining rings are located on both sides of the linkage gear ring and are used to limit the rotation position of the linkage gear ring.

[0028] Several tie rods are arranged below the linkage gear ring.

[0029] Preferably, the limiting structure includes:

[0030] Fixed plates are installed on the outer surface of the storage compartment;

If storage space is insufficient, a rotating linkage gear ring can control the expansion compartment to move upwards, creating additional storage space between the expansion compartment and the storage compartment. Furthermore, by adjusting the gears and lifting screw, the lifting height of the expansion compartment can be adjusted in multiple stages to regulate the degree of lifting based on the amount of rubber powder stored, thus preventing the expansion compartment from rising too high and occupying excessive space.

[0043] In this invention, the rubber powder poured into the storage chamber is blocked by the annular partition plate, preventing the rubber powder from directly contacting the expansion chamber. This ensures that the expansion chamber is not affected by the rubber powder during lifting and adjustment, making the lifting and lowering operation of the expansion chamber smoother. Furthermore, the annular partition plate is designed to be detachable. By continuously rotating the linkage gear ring to remove the expansion chamber and then unscrewing the fixing screw, the annular partition plate can be removed from the storage chamber for cleaning of the inner wall of the annular partition plate or for replacement of the annular partition plate.

[0052] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0053] Example 1:

[0054] like Figures 1 to 5As shown, this utility model provides a rubber powder storage sealing device, including: a storage chamber 1 for storing rubber powder and a support column 2 arranged on the storage chamber 1 for supporting the storage chamber 1, and a storage structure arranged on the storage chamber 1 for expanding the storage space of the storage chamber 1.

[0055] The storage structure includes an expansion structure for increasing the storage space of storage compartment 1, an adjustment structure for adjusting the size of the storage space of the expansion structure, and a limiting structure for restricting the position of the expansion structure.

[0056] The expansion structure includes an expansion chamber 3 movably installed inside the storage chamber 1, a lifting screw 301 arranged on the expansion chamber 3, and a movable groove 302 opened inside the support column 2 to limit the movement direction of the lifting screw 301. The lifting screw 301 is slidably installed in the movable groove 302. The rise of the expansion chamber 3 can create additional space between the storage chamber 1 and the expansion chamber 3, which can store additional rubber powder. When the lifting screw 301 moves, it can slide in the movable groove 302 and push the expansion chamber 3 to rise.

[0057] The adjustment structure includes a U-shaped frame 303 arranged at one end of the support column 2, the U-shaped frame 303 being slidably sleeved on the lifting screw 301, an adjustment gear 304 being rotatably installed inside the U-shaped frame 303, a threaded hole 305 being opened inside the adjustment gear 304, the lifting screw 301 being threadedly installed in the threaded hole 305, and a limiting component arranged on the adjustment gear 304 for limiting the rotational position of the adjustment gear 304. The rotating adjustment gear 304 can drive the lifting screw 301 to move up and down by engaging with the threaded connection between the threaded hole 305 and the lifting screw 301.

[0058] Specifically, the limiting components include an annular groove 306 formed inside the adjusting gear 304 and a limiting ring 307 arranged inside the U-shaped frame 303. The limiting ring 307 is rotatably mounted in the annular groove 306. When the adjusting gear 304 rotates, it can rotate on the limiting ring 307 through the annular groove 306, thereby preventing the position of the adjusting gear 304 from shifting when it rotates.

[0059] The adjustment structure also includes a linkage gear ring 308 rotatably sleeved on the storage chamber 1, which meshes with the adjustment gear 304. Two retaining rings 309 are fixedly sleeved on the storage chamber 1 to limit the rotation position of the linkage gear ring 308. The two retaining rings 309 are located on both sides of the linkage gear ring 308. Several pull rods 310 are arranged below the linkage gear ring 308. Pushing the pull rods 310 drives the linkage gear ring 308 to rotate. By setting retaining rings 309 on both sides of the linkage gear ring 308, the rotation position of the linkage gear ring 308 can be limited to prevent it from deviating. The rotating linkage gear ring 308 can drive the adjustment gear 304 to rotate by meshing with the adjustment gear 304.

[0060] The limiting structure includes a fixed plate 4 arranged on the outer surface of the storage compartment 1, a guide rod 401 arranged below the fixed plate 4, a limiting slider 402 slidably sleeved on the guide rod 401, a limiting tooth block 403 arranged on one side of the limiting slider 402, the limiting tooth block 403 meshing with the linkage tooth ring 308, and a handle 404 arranged on one side of the limiting slider 402. The limiting tooth block 403 can restrict the linkage tooth ring 308 to prevent it from rotating and loosening. Pulling the handle 404 down can drive the limiting slider 402 to slide on the guide rod 401. The moving limiting slider 402 can drive the limiting tooth block 403 to disengage from the linkage tooth ring 308, thus releasing the restriction on the linkage tooth ring 308.

[0061] The limiting structure also includes a stop bar 405 arranged at one end of the guide rod 401 and a spring 406 arranged between the limiting slider 402 and the stop bar 405. The spring 406 is slidably sleeved on the guide rod 401. The downward moving limiting slider 402 can compress the spring 406 through cooperation with the stop bar 405. When the handle 404 is released, the compressed spring 406 will push the limiting slider 402 to rise and reset.

[0062] Example 2:

[0063] Based on Example 1, in order to avoid the expansion chamber 3 being affected by the rubber powder in the storage chamber 1 when it moves up and down, a separation structure is arranged inside the storage chamber 1 to separate the expansion structure from the rubber powder stored in the storage chamber 1.

[0064] The separation structure includes an annular partition plate 5 movably installed inside the storage chamber 1. The annular partition plate 5 is located inside the expansion chamber 3. A fixing screw 501 is threaded into the storage chamber 1 and the annular partition plate 5 to limit the position of the annular partition plate 5. The rubber powder in the storage chamber 1 is protected by the annular partition plate 5, so that the expansion chamber 3 will not be affected by the rubber powder when it rises. By continuously rotating the linkage gear ring 308, the lifting screw 301 can be continuously raised and disengaged from the support column 2, thereby separating the expansion chamber 3 from the storage chamber 1. Then, by unscrewing the fixing screw 501 from the annular partition plate 5 and the storage chamber 1, the annular partition plate 5 can be pulled out for replacement or cleaning.

[0065] Working principle:

[0066] In use, the expansion chamber 3 can be opened, and then the rubber powder can be poured into the storage chamber 1 for storage. The rubber powder will be located inside the annular partition plate 5. When the storage space is insufficient, the handle 404 can be pulled down to drive the limiting slider 402 to slide on the guide rod 401. The guide rod 401 can limit the movement direction of the limiting slider 402 to prevent it from deviating. The descending limiting slider 402 can compress the spring 406 through its cooperation with the stop bar 405. At the same time, the limiting slider 402 will drive the limiting tooth block 403 to disengage from the linkage tooth ring 308. At this point, the restriction on the linkage gear ring 308 can be released, and then the pull rod 310 can be pushed to drive the linkage gear ring 308 to rotate. By setting retaining rings 309 on both sides of the linkage gear ring 308, the rotation position of the linkage gear ring 308 can be restricted to prevent it from deviating. The rotating linkage gear ring 308 can drive the adjusting gear 304 to rotate by meshing with the adjusting gear 304. The continuously rotating adjusting gear 304 can drive the lifting screw 301 to move up and down by threading with the lifting screw 301 through the thread hole 305, so that the lifting screw 301 moves up and down in the movable groove 3. The expansion chamber 3 is pushed upward by sliding within the storage chamber 1. Because the rubber powder in the storage chamber 1 is protected by the annular partition plate 5, the expansion chamber 3 is not affected by the rubber powder during its ascent. The rise of the expansion chamber 3 creates additional space between the storage chamber 1 and the expansion chamber 3, allowing for the storage of additional rubber powder. The degree of rise of the expansion chamber 3 can be adjusted according to the amount of rubber powder stored. After adjustment, the handle 404 is released. At this time, the compressed spring 406 pushes the limit slider 402 upward to reset, thereby causing the limit tooth block 403 to re-engage with the linkage tooth ring 308. To prevent the linkage gear ring 308 and the adjusting gear 304 from rotating and becoming loose, the stability of the lifting screw 301 and the expansion chamber 3 is ensured. In addition, the annular partition plate 5 in the storage chamber 1 adopts a detachable design. By continuously rotating the linkage gear ring 308, the lifting screw 301 can be continuously raised and disengaged from the support column 2, thereby separating the expansion chamber 3 from the storage chamber 1. Then, by unscrewing the fixing screw 501 from the annular partition plate 5 and the storage chamber 1, the restriction on the annular partition plate 5 can be released, so that the annular partition plate 5 can be pulled out for replacement or cleaning.

[0067] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
