Description

Technical Field

[0001] This invention relates to the field of single-walled tube packaging technology, specifically a packaging bag for single-walled tubes with a self-sealing function for venting. Background Technology

[0002] Single-walled carbon nanotubes (SWNTs) are nanostructured materials composed of rolled carbon atoms. They possess high tensile strength, excellent electrical conductivity, thermal conductivity, and mechanical properties. SWNTs have extremely small diameters, typically ranging from a few nanometers to tens of nanometers, and are widely studied and applied in numerous fields. After production, SWNTs are usually packaged in granular form. To facilitate storage and ensure they are not contaminated or damaged, they are packaged in bags.

[0003] When packaging single-walled carbon nanotubes, existing packaging bags lack an exhaust and self-sealing function during the packaging process. As the single-walled carbon nanotubes clump together in the packaging bag, tiny gaps remain between the particles. These gaps trap air inside the packaging bag, increasing its volume and thus transportation and storage costs. Summary of the Invention

[0004] The purpose of this invention is to provide a packaging bag for a single-walled tube with a self-sealing function for venting, so as to solve the problems mentioned in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A single-walled tube packaging bag with exhaust self-sealing function includes a main body, a feeding pipe installed at the top of the main body, a control valve installed at the output end of the feeding pipe, a guide rail installed on the main body, a slide seat slidably installed on the guide rail, a clamping component installed on the slide seat, and a packaging bag clamped on the clamping component. An electric push rod is installed at the lower part of the main body, an outer can is installed on the electric push rod, a slide rail is installed on the feeding pipe, two movable seats are slidably installed on the slide rail, an electric telescopic rod is installed at the bottom of each of the two movable seats, and a heat sealer is installed on the electric telescopic rod. When needed... When packaging single-walled carbon nanotubes, the guide rail is activated, causing the slide to move the packaging bag to the packaging position via the clamping device. At this time, the opening and closing of the control valve allows the feeding pipe to quantitatively feed material into the packaging bag on the clamping device. After feeding is completed, the electric push rod is activated, which can drive the outer can to move rapidly longitudinally back and forth. This back and forth movement of the outer can creates a bumping motion on the packaging bag, which helps to squeeze the granular single-walled tubes inside the packaging bag together. This reduces and squeezes out the air entering the packaging bag, thus achieving air venting. After air venting is completed, the guide rail and electric telescopic rod are activated, allowing the two heat sealers to move to the packaging bag for heat sealing and self-closure.

[0006] As a preferred technical solution, during the loading process, when the slide moves along the guide rail to the packaging position, the output end of the conveying pipe, the packaging bag on the clamping component, and the outer can are on the same longitudinal central axis.

[0007] As a preferred technical solution, the main body is provided with a primary exhaust enhancement component and a secondary exhaust enhancement component, and the movement of the outer can provides the driving force for the primary exhaust enhancement component and the secondary exhaust enhancement component.

[0008] As a preferred technical solution, the exhaust first-stage enhancement component includes a linkage rod, a linkage ring, a transmission ring tooth, a force-bearing shaft, a fixing block, a fixing column, a spiral slide, a rotating ring, an inner canister, a driven ring tooth, and a transmission chain; A linkage rod is installed on the upper part of the outer can, and a linkage ring is installed on the linkage rod. A transmission ring gear is rotatably installed on the linkage ring, and a force-bearing shaft is installed inside the transmission ring gear. A fixing block is installed on the side of the main body near the outer can, and a fixing post is installed at the bottom of the fixing block. The fixing post passes through the transmission ring gear and the linkage ring, and a spiral slide is provided on the side wall of the fixing post. The force-bearing shaft slides through the spiral slide. A rotating ring is rotatably installed at the port of the outer can, and an inner can is installed on the rotating ring. The inner can is inside the outer can. Equipped with driven ring teeth, and a transmission chain fitted onto the driven ring teeth and transmission ring teeth, when the outer can moves longitudinally, the outer can can drive the transmission ring teeth to move synchronously through the linkage rod and linkage ring. Utilizing the squeezing action of the spiral slide on the force-bearing shaft, the transmission ring teeth can rotate during the movement. During the rotation of the transmission ring teeth, they can drive the driven ring teeth to rotate together with the transmission chain, thereby causing the driven ring teeth to drive the inner can to rotate synchronously. This facilitates the inner can driving the packaging bag to rotate, thereby enhancing the squeezing effect of the granular single-walled tubes inside the bag and improving the exhaust effect.

[0009] As a preferred technical solution, the inner wall of the inner can is equipped with multiple protrusions, which can increase the friction between the inner can and the packaging bag, ensuring that the inner can drives the packaging bag to rotate.

[0010] As a preferred technical solution, the exhaust first-stage enhancement component further includes an extrusion curved plate, a fixing plate, an opening, a fixing shaft, a rocker arm, a connecting hole, a force-bearing ball, an impact ball, and a square hole; The upper end of the rotating ring is equipped with multiple extrusion plates arranged in a circular pattern. The upper part of the outer canister is equipped with multiple fixing plates, each with an opening. A fixing shaft is installed within each opening, and a swing rod is mounted on the fixing shaft. The swing rod has a connecting hole through which the fixing shaft passes, and they are rotatably fitted. A force-receiving ball is rotatably mounted at the upper end of the swing rod, and an impact ball is rotatably mounted at the lower end. The upper part of the outer canister has multiple square holes, each corresponding to a specific impact ball. When the rotating ring rotates, it drives the extrusion plates to rotate synchronously. The rapid extrusion of the force-receiving ball by the extrusion plates during rotation allows the force-receiving ball to move in an arc shape via the swing rod during displacement. This allows the impact ball to impact the rotating inner canister through the square holes, further enhancing the extrusion effect between the granular single-walled tubes through vibration, thereby improving the exhaust effect.

[0011] As a preferred technical solution, the lower part of the swing arm is connected to the outer can through a support spring, which allows the swing arm to drive the force ball to quickly return to its original position.

[0012] As a preferred technical solution, the exhaust secondary enhancement component includes a servo motor, a rotating rod, a connecting air pipe, and an air cover; A servo motor is installed at the lower part of the main body. The output shaft of the servo motor is connected to a rotating rod via a coupling. A connecting air pipe is installed on the rotating rod, and an air cap is installed on the connecting air pipe. The servo motor is electrically connected to an electric push rod. When the electric push rod is running, the servo motor can drive the connecting air pipe to rotate 90° via the rotating rod, thereby allowing the air cap to move to the opening of the packaging bag of the clamping component to form a cover, which can prevent the granular single-walled tubes inside the bag from scattering during bumping. When the electric push rod stops, the servo motor can drive the air cap to rotate 90° via the rotating rod, thereby allowing the air cap to be transferred from the opening of the packaging bag.

[0013] As a preferred technical solution, the exhaust secondary enhancement assembly further includes a housing, a sliding plug, a plug rod, a sliding hole, a transmission plate, an intake pipe, and an exhaust pipe; A housing is mounted on the main body, and a sliding plug is slidably installed inside the housing, forming two air chambers within the housing. A plug rod is installed at the upper end of the sliding plug, and a sliding hole is opened at the top of the housing. A transmission plate is mounted on the linkage ring, and the plug rod passes through the sliding hole and connects to the bottom of the transmission plate. The input ends of both air chambers are connected to a connecting air pipe through an air suction pipe, forming an airflow channel through the air cover, connecting air pipe, and air suction pipe. An exhaust pipe is installed on the output ends of both air chambers. When the linkage ring moves longitudinally back and forth, it can drive the transmission plate to move synchronously, allowing the transmission plate to drive the sliding plug to move synchronously back and forth within the housing via the plug rod. The reciprocating movement of the sliding plug allows the two air chambers to operate alternately, thereby continuously absorbing the gas discharged from the packaging bag through the airflow channel formed by the air cover, connecting air pipe, and air suction pipe, and then discharging it through the exhaust pipe, effectively preventing airflow from flowing back into the packaging bag.

[0014] As a preferred technical solution, both the intake pipe and the exhaust pipe are unidirectional pipes.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This application allows the electric push rod to be activated after the feeding and bagging are completed, driving the outer bag can to move rapidly in a longitudinal reciprocating motion. This reciprocating motion of the outer bag can create a bumping motion on the packaging bag, which helps to squeeze the granular single-walled tubes inside the packaging bag together. This reduces and squeezes out the air entering the packaging bag, thus achieving air exhaust. After the air exhaust is completed, the two heat sealers can be moved to the packaging bag for heat sealing and self-closure by activating the slide rail and electric telescopic rod.

[0016] This application, through the provision of a primary exhaust enhancement component, utilizes the longitudinal movement of the outer can to cause the inner can to rotate, thereby enhancing the squeezing effect of the granular single-walled tubes inside the bag, improving the exhaust effect, and creating an impact on the inner can, which further enhances the squeezing effect between the granular single-walled tubes through vibration, thus improving the exhaust effect.

[0017] This application, through the exhaust secondary utilization component, can cover the opening of the packaging bag with the air cover during exhaust, which can prevent the granular single-wall tubes inside the bag from scattering during bumping. It can also form an airflow channel through the air cover, connecting air pipe and suction pipe to continuously absorb the gas discharged from the packaging bag, which can effectively prevent the airflow from flowing back into the packaging bag.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example: Figures 1-4As shown, the present invention provides a technical solution for a single-walled tube packaging bag holder with a self-sealing function for venting. This single-walled tube packaging bag holder includes a main body 1, a feeding pipe 2 mounted on the top of the main body 1, a control valve 3 mounted on the output end of the feeding pipe 2, a guide rail 4 mounted on the main body 1, a slide seat 5 slidably mounted on the guide rail 4, a clamping component 6 mounted on the slide seat 5, and a packaging bag clamped on the clamping component 6. An electric push rod 7 is mounted on the lower part of the main body 1, an outer can 8 mounted on the electric push rod 7, a slide rail 9 mounted on the feeding pipe 2, two movable seats 10 slidably mounted on the slide rail 9, and an electric telescopic rod 11 mounted at the bottom of each of the two movable seats 10. A heat sealer 12 is mounted on the electric telescopic rod 11. When… When packaging single-walled carbon nanotubes, the guide rail 4 is activated, causing the slide 5 to move the packaging bag to the packaging position via the clamping component 6. At this time, the opening and closing of the control valve 3 causes the feeding pipe 2 to feed a quantitative amount of material into the packaging bag on the clamping component 6. After feeding is completed, the electric push rod 7 is activated, which can drive the outer bag 8 to move rapidly in the longitudinal direction. This causes the outer bag 8 to bounce against the packaging bag during the reciprocating movement, which is beneficial for the granular single-walled tubes in the packaging bag to squeeze each other, which can reduce and squeeze out the air entering the packaging bag, thus achieving the exhaust of the packaging bag. After the exhaust is completed, the guide rail 9 and the electric telescopic rod 11 are activated, which can move the two heat sealers 12 to the packaging bag for heat sealing and self-closure.

[0022] During loading, when the slide 5 moves along the guide rail 4 to the packaging position, the output end of the conveying pipe 2, the packaging bag on the clamping piece 6, and the outer can 8 are on the same longitudinal central axis.

[0023] The main body 1 is equipped with a primary exhaust enhancement component 13 and a secondary exhaust enhancement component 14, and the movement of the outer canister 8 provides the driving force for the primary exhaust enhancement component 13 and the secondary exhaust enhancement component 14.

[0024] like Figures 1-9 As shown, the exhaust stage enhancement component 13 includes a linkage rod 1301, a linkage ring 1302, a transmission ring gear 1303, a force-bearing shaft 1304, a fixing block 1305, a fixing column 1306, a spiral slide 1307, a rotating ring 1308, an inner canister 1309, a driven ring gear 1310, and a transmission chain 1311. A linkage rod 1301 is installed on the upper part of the outer can 8. A linkage ring 1302 is installed on the linkage rod 1301. A transmission ring gear 1303 is rotatably installed on the linkage ring 1302. A force-bearing shaft 1304 is installed inside the ring of the transmission ring gear 1303. A fixing block 1305 is installed on the side of the main body 1 near the outer can 8. A fixing post 1306 is installed at the bottom of the fixing block 1305. The fixing post 1306 passes through the transmission ring gear 1303 and the linkage ring 1302. A spiral slide 1307 is provided on the side wall of the fixing post 1306. The force-bearing shaft 1304 slides through the spiral slide 1307. A rotating ring 1308 is rotatably installed at the port of the outer can 8. An inner can 1309 is installed on the rotating ring 1308. The inner can 1309 is inside the outer can 8. The outer can 8 is equipped with a driven ring gear 1310. A transmission chain 1311 is fitted onto the driven ring gear 1310 and the transmission ring gear 1303. When the outer can 8 moves longitudinally, the outer can 8 can drive the transmission ring gear 1303 to move synchronously through the linkage rod 1301 and the linkage ring 1302. By utilizing the squeezing action of the spiral slide 1307 on the force shaft 1304, the transmission ring gear 1303 can rotate during the movement. During the rotation, the transmission ring gear 1303 can drive the driven ring gear 1310 to rotate together with the transmission chain 1311, thereby allowing the driven ring gear 1310 to drive the inner can 1309 to rotate synchronously. This is beneficial for the inner can 1309 to drive the packaging bag to rotate, thereby enhancing the squeezing action of the granular single-walled tubes inside the bag and improving the exhaust effect.

[0025] Multiple protrusions are installed on the inner wall of the inner can 1309 to increase the friction between the inner can 1309 and the packaging bag, ensuring that the inner can 1309 drives the packaging bag to rotate.

[0026] The exhaust stage enhancement assembly 13 also includes an extrusion curved plate 1312, a fixing plate 1313, an opening 1314, a fixing shaft 1315, a rocker arm 1316, a connecting hole 1317, a force-bearing ball 1318, an impact ball 1319, and a square hole 1320; Multiple extrusion plates 1312 are arranged in a circular pattern on the upper end of the rotating ring 1308. Multiple fixing plates 1313 are installed on the upper part of the outer can 8. Each fixing plate 1313 has an opening 1314, within which a fixing shaft 1315 is installed. A rocker arm 1316 is mounted on the fixing shaft 1315. A connecting hole 1317 is provided on the rocker arm 1316, through which the fixing shaft 1315 passes and is rotatably fitted. A force-receiving ball 1318 is rotatably mounted on the upper end of the rocker arm 1316, and an impact ball 1319 is rotatably mounted on the lower end of the rocker arm 1316. Multiple square holes 132 are provided on the upper part of the outer can 8. 0. Multiple square holes 1320 correspond one-to-one with multiple impact balls 1319. When the rotating ring 1308 rotates, the rotating ring 1308 can drive the extrusion plate 1312 to rotate synchronously. By using the rapid extrusion of the extrusion plate 1312 on the force ball 1318 during the rotation, the force ball 1318 can drive the impact ball 1319 to move in an arc shape through the swing rod 1316 during the displacement process. Thus, the impact ball 1319 can impact the inner can 1309 during the rotation process through the square holes 1320. The extrusion effect between the granular single-wall tubes can be further improved through the vibration force, thereby improving the exhaust effect.

[0027] The lower part of the swing arm 1316 is connected to the outer can 8 through the support spring 1321. The support spring 1321 can enable the swing arm 1316 to drive the force ball 1318 to quickly return to its original position.

[0028] like Figures 1-5 , Figure 7 and Figure 9 As shown, the exhaust secondary enhancement assembly 14 includes a servo motor 1401, a rotating rod 1402, a connecting air pipe 1403, and an air cover 1404; A servo motor 1401 is installed at the lower part of the main body 1. The output shaft of the servo motor 1401 is connected to a rotating rod 1402 via a coupling. A connecting air pipe 1403 is installed on the rotating rod 1402, and an air cover 1404 is installed on the connecting air pipe 1403. The servo motor 1401 is electrically connected to the electric push rod 7. When the electric push rod 7 is running, the servo motor 1401 can drive the connecting air pipe 1403 to rotate 90° via the rotating rod 1402, so that the air cover 1404 can be moved to the opening of the packaging bag of the clamping part 6 to form a cover, which can prevent the granular single-wall tubes inside the bag from scattering during the bumping process. When the electric push rod 7 stops, the servo motor 1401 can drive the air cover 1404 to rotate 90° via the rotating rod 1402, so that the air cover 1404 is transferred from the opening of the packaging bag.

[0029] The exhaust secondary enhancement assembly 14 also includes a housing 1405, a sliding plug 1406, a plug rod 1407, a sliding hole 1408, a transmission plate 1409, an intake pipe 1410, and an exhaust pipe 1411; A housing 1405 is mounted on the main body 1. A sliding plug 1406 is slidably installed inside the housing 1405, forming two air chambers within the housing 1405. A stopper rod 1407 is mounted on the upper end of the stopper 1406. A sliding hole 1408 is provided on the top of the housing 1405. A transmission plate 1409 is mounted on the linkage ring 1302. The stopper rod 1407 passes through the sliding hole 1408 and is connected to the bottom of the transmission plate 1409. The input ends of both air chambers are connected to the connecting air pipe 1403 through the suction pipe 1410, forming an airflow channel through the air cover 1404, the connecting air pipe 1403, and the suction pipe 1410. The air inlet of the two air chambers... Each end is equipped with an exhaust pipe 1411. When the linkage ring 1302 moves longitudinally back and forth, the linkage ring 1302 can drive the transmission plate 1409 to move synchronously. The transmission plate 1409 can drive the sliding plug 1406 to move synchronously back and forth in the box 1405 through the plug rod 1407. The reciprocating movement of the sliding plug 1406 can make the two air chambers run alternately. Thus, the airflow channel formed by the air cover 1404, the connecting air pipe 1403 and the suction pipe 1410 can continuously absorb the gas discharged from the packaging bag and then discharge it through the exhaust pipe 1411. This can effectively prevent the airflow from flowing back into the packaging bag.

[0030] Both the intake pipe 1410 and the exhaust pipe 1411 are unidirectional pipes.

[0031] Working principle of the invention: When single-walled carbon nanotubes need to be packaged, the guide rail 4 is activated, causing the slide 5 to move the packaging bag to the packaging position via the clamping member 6. At this time, the opening and closing of the control valve 3 causes the feeding pipe 2 to feed a quantitative amount of material into the packaging bag on the clamping member 6. After feeding is completed, the electric push rod 7 is activated, which can drive the outer bag 8 to move rapidly in the longitudinal direction. This causes the outer bag 8 to bounce against the packaging bag during the reciprocating movement, which is beneficial for the granular single-walled tubes in the packaging bag to squeeze each other, which can reduce and squeeze out the air entering the packaging bag, thus achieving the exhaust of the packaging bag. After the exhaust is completed, the guide rail 9 and the electric telescopic rod 11 are activated, which can move the two heat sealers 12 to the packaging bag for heat sealing and self-closure.

[0032] When the outer can 8 moves longitudinally, it can drive the transmission ring gear 1303 to move synchronously via the linkage rod 1301 and linkage ring 1302. The compression of the force-bearing shaft 1304 by the spiral slide 1307 allows the transmission ring gear 1303 to rotate during movement. This rotation, along with the transmission chain 1311, drives the driven ring gear 1310 to rotate, thus causing the driven ring gear 1310 to drive the inner can 1309 to rotate synchronously. This facilitates the rotation of the packaging bag by the inner can 1309, thereby enhancing the rotation of the granular contents inside the bag. The squeezing effect of the wall tubes improves the exhaust effect. When the rotating ring 1308 rotates, it can drive the squeezing curved plate 1312 to rotate synchronously. The squeezing curved plate 1312 rapidly squeezes the force ball 1318 during the rotation, allowing the force ball 1318 to drive the impact ball 1319 to move in an arc shape through the swing rod 1316 during the displacement process. This allows the impact ball 1319 to impact the inner canister 1309 during the rotation process through the square hole 1320. The squeezing effect between the granular single-wall tubes can be further improved through the vibration force, thereby improving the exhaust effect.

[0033] When the electric push rod 7 is running, the servo motor 1401 can drive the connecting air pipe 1403 to rotate 90° via the rotating rod 1402, so that the air cover 1404 can move to the opening of the packaging bag of the clamping part 6 to form a cover, which can prevent the granular single-wall tubes inside the bag from scattering during the bumping process. In addition, when the linkage ring 1302 moves longitudinally back and forth, the linkage ring 1302 can drive the transmission plate 1409 to move synchronously, so that the transmission plate 1409 can drive the sliding plug 1406 to move synchronously back and forth in the box 1405 via the plug rod 1407. The reciprocating movement of the sliding plug 1406 can make the two air chambers run alternately, so that the air cover 1404, the connecting air pipe 1403 and the suction pipe 1410 can form an airflow channel to continuously absorb the gas discharged from the packaging bag, and then discharge it through the exhaust pipe 1411, which can effectively prevent the airflow from flowing back into the packaging bag.

[0034] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
