Description

Technical Field

[0001] The invention relates to the technical field of single-wall tube transportation, in particular to a single-wall tube transportation device with a flexible packaging function. Background Art

[0002] Single-walled tubes, also known as single-walled carbon nanotubes, have nanoscale tube diameters, excellent mechanical strength, and outstanding electrical properties, making them ideal materials for building next-generation microelectronic devices. During the transportation and packaging process, single-walled tubes are easily adsorbed on the inner wall of the transportation tube due to their special physical properties.

[0003] To ensure efficient single-walled tube transportation, cleaning mechanisms are typically installed within the pipeline. For example, patents "CN221116025U, A Device for Transporting Carbon Nanotube Powders" and "CN119262848A, A Device for Transporting Single-Walled Carbon Nanotube Powders," respectively disclose a technical solution for cleaning the pipeline. However, existing technologies have limitations. In actual work scenarios, pipelines are often very long and have many curved ends. Current cleaning methods are difficult to adapt to pipelines of varying shapes and lengths. They generally employ one-way friction against the inner wall of the pipeline, failing to provide rotational or reciprocating friction. This makes cleaning effectiveness difficult to guarantee. Finally, regarding packaging, conventional devices are typically designed for only a single packaging format, such as packaging in bags or bottles. This makes it difficult for companies to quickly switch packaging formats when market demand changes, hindering work efficiency. Furthermore, if the amount of single-walled tubes dropped during the packaging process exceeds the rated weight, conventional devices typically lack an effective excess recovery mechanism, making it impossible to recycle and reuse the excess tubes. Summary of the Invention

[0004] The object of the present invention is to provide a single-wall tube conveying device with a flexible packaging function to solve the problems raised in the prior art.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a single-wall tube conveying device with a flexible packaging function, the single-wall tube conveying device includes a storage tank, a conveying mechanism and a vacuum box, the upper and lower ends of the storage tank are respectively provided with a feed valve and a discharge valve, one end of the conveying mechanism is connected to the feed valve, and the other end of the conveying mechanism is connected to the single-wall tube preparation equipment, the top of the vacuum box is provided with a blanking mechanism, the blanking mechanism is connected to the discharge valve, and a flexible packaging mechanism is provided below the blanking mechanism. When the present invention is working, the single-wall tube produced by the single-wall tube preparation equipment will enter the storage tank along the conveying mechanism and the feed valve (the method of the single-wall tube flowing into the storage tank belongs to the conventional technical means in this field, and the specific structure and The implementation method is not described here), the produced single-walled tubes are temporarily stored in a storage tank. When the staff needs to package the single-walled tubes in the storage tank, the staff can place the packaging bag or packaging bottle in the flexible packaging mechanism, and then open the discharge valve. At this time, the single-walled tube will fall into the packaging bag or packaging bottle along the blanking mechanism, and the packaging bag or packaging bottle will be quantitatively packaged by the flexible packaging mechanism. Finally, compared with the current single-walled tube conveying device, the blanking mechanism in the present invention has an excess recovery function. When the single-walled tubes that fall into the packaging bag or packaging bottle exceed the rated amount due to various reasons such as misoperation, the staff can use the blanking mechanism to suck the excess single-walled tubes out of the packaging bag or packaging bottle to ensure that the weight of the packaged single-walled tubes meets the standard.

[0006] Furthermore, the flexible packaging mechanism includes a packaging box and two movable frames, which are relatively arranged at the upper ends of the packaging box, each movable frame is connected to the vacuum box through a group of third cylinders, and the two movable frames are controlled to move closer to and away from each other by two groups of third cylinders.

Bottle caps are provided on the placement frame, and the mounting frame is connected to the vacuum box through a linear motor. A clamp is provided below the mounting frame, and a second cylinder is provided above the mounting frame, and the movement of the clamp is controlled by the second cylinder.

[0007] Furthermore, the flexible packaging mechanism also includes a base and a lifting seat, the base and the lifting seat are connected through a lifting module, a weighing plate is provided at the upper end of the lifting seat, and the weighing plate and the lifting seat are connected through a piezoelectric element and a compression spring.

[0008] When the single-wall tubes in the storage tank are to be packaged into packaging bags, the staff can fix the upper ends of the packaging bags with the vacuum suction cups in the two movable frames, and then open the lifting module to make the lifting seat and the weighing plate rise until the packaging bag is in a relaxed state. At this time, the discharge valve is opened, and the single-wall tubes will fall into the packaging bag along the blanking mechanism. The staff can know the weight of the single-wall tubes falling into the packaging bag by detecting the electrical signal generated by the piezoelectric element. When the single-wall tubes falling into the packaging bag reach the rated amount, the staff can close the discharge valve, and then use the two sets of third cylinders to make the two movable frames close to each other, and open the hot pressing plate to heat-seal the packaging bag through the hot pressing plate. When the single-wall tubes in the storage tank are to be packaged into packaging bottles, the staff can directly Then place the packaging bottle on the weighing plate, and then open the discharge valve. At this time, the single-walled tube will fall into the packaging bottle along the blanking mechanism. Similarly, the staff can know the weight of the single-walled tube falling into the packaging bottle by detecting the electrical signal generated by the piezoelectric element. When the single-walled tube falling into the packaging bottle reaches the rated amount, the staff can close the discharge valve, and then clamp the bottle cap set on the placement rack with the clamping claw, and then place the bottle cap into the packaging bottle through the cooperation of the linear motor and the second cylinder. Compared with the current single-walled tube conveying device, the present invention can quickly switch between the two packaging forms of packaging bags and packaging bottles through simple operations, which significantly improves the overall production efficiency. On the other hand, it can detect the weight of the single-walled tube falling into the packaging bottle or packaging bag in real time, thereby greatly improving the packaging accuracy.

[0009] Furthermore, the blanking mechanism includes a blanking funnel, a first cylinder and a telescopic cylinder. The telescopic cylinder is arranged on the outside of the lower end of the blanking funnel. The first cylinder is arranged on the blanking funnel. The working end of the first cylinder is connected to the telescopic cylinder. The telescopic cylinder is controlled by the first cylinder to perform lifting and lowering movements on the outside of the lower end of the blanking funnel, so that when the single-walled tube is transported into the packaging bottle or packaging bag, the telescopic cylinder can be extended into the packaging bottle or packaging bag, thereby reducing the risk of splashing of the single-walled tube.

[0010] Furthermore, a guide groove is provided inside the telescopic cylinder, a filter is provided in the middle position of the guide groove, the upper end of the guide groove is connected to the external suction fan through a hose, and the lower end area of ​​the guide groove is provided with an arc structure. During the packaging process of the present invention, if it is detected that the single-walled tube falling into the packaging bag or the packaging bottle exceeds the rated weight, the staff can turn on the external fan to generate a set of suction force through the external fan. At this time, the excess single-walled tube in the packaging bag or the packaging bottle will be sucked into the guide groove and intercepted by the filter. When the external fan is turned off, the single-walled tube intercepted by the filter will fall into the arc-shaped structure at the lower end of the guide groove. area, thereby serving the purpose of caching the single-wall tubes. Through the above technical scheme, the present invention further ensures the accuracy of single-wall tube packaging. When the staff puts a new packaging bag or packaging bottle under the blanking mechanism, the staff can first turn on the external fan to generate a set of blowing force through the external fan, so that the single-wall tubes cached in the arc-shaped area at the lower end of the guide groove and the single-wall tubes remaining on the filter screen flow with the air into the new packaging bag or packaging bottle. Compared with the current single-wall tube conveying device, the present invention can automatically recycle excess single-wall tubes, further reduce the weight error, and reduce the trouble of manual processing.

[0011] Furthermore, the conveying mechanism includes a positioning frame and a conveying pipe, the positioning frame is arranged above the conveying pipe, and a first positioning magnet is arranged inside the positioning frame, the conveying pipe is connected to the single-walled pipe preparation equipment through the feed port, and the conveying pipe is connected to the feed valve through the second discharge port, and a cleaning ball is arranged at one end of the conveying pipe near the second discharge port, and a second positioning magnet is arranged on the upper end of the cleaning ball, the first positioning magnet and the second positioning magnet are aligned and attract each other, and the diameter of the cleaning ball is larger than the diameter of the second discharge port. In the process of conveying the single-walled pipe of the present invention, the single-walled pipe flows into the storage tank along the feed port, the conveying pipe, the second discharge port, and the feed valve. When the single-walled pipe conveying work is completed, the present invention can close the feed valve and the outlet end of the single-walled pipe preparation equipment. At this time, the staff can indirectly drive the cleaning ball to move synchronously in the conveying pipe by controlling the first positioning magnet to move in the positioning frame. During the movement of the cleaning ball, the conveying pipe can be cleaned by the cleaning ball to avoid some single-walled pipes from being adsorbed on the inner wall of the conveying pipe due to static electricity and other reasons, causing blockage.

[0012] Furthermore, a sealing end cap is provided at one end of the conveying pipe near the second discharge port, a first discharge port is provided at one end of the conveying pipe near the feed port, a sealing plug is provided inside the first discharge port, and the end of the sealing plug near the conveying pipe is flush with the inner wall of the conveying pipe. The present invention ensures that during the process of conveying the single-walled tube, the single-walled tube can flow smoothly through the first discharge port through the sealing plug. When the cleaning ball cleans the single-walled tube adsorbed on the inner wall of the conveying tube to the first discharge port, the staff can remove the sealing plug from the first discharge port to discharge the single-walled tube out of the conveying pipe.

[0013] Furthermore, a first conduit and a second conduit are respectively provided at both ends of the positioning frame, the first conduit is provided at one end of the positioning frame close to the sealing end cover, and the second conduit is provided at one end of the positioning frame close to the first discharge port, and the first conduit and the second conduit are both connected to an external liquid pump.

At this time, the pressure at one end of the positioning frame close to the sealing end cover rises rapidly. In the closed positioning frame space, this part of the pressure will act on the side of the first positioning magnet close to the first conduit. Under the action of the hydraulic pressure, the first positioning magnet will move along the positioning frame toward the second conduit, and the first positioning magnet will drive the cleaning ball in the conveying pipe during the movement. The cleaning ball and the first positioning magnet move synchronously in the delivery pipe to achieve the purpose of cleaning the delivery pipe. When the cleaning of the delivery pipe is completed and the first positioning magnet and the cleaning ball need to be reset, the staff can inject liquid into the second conduit through an external liquid pump. At the same time, the first conduit serves as a liquid return channel. At this time, under the action of the hydraulic pressure, the first positioning magnet and the cleaning ball will be reset to their initial positions for subsequent use. Compared with the current technical solution for cleaning the delivery pipe of the single-walled tube delivery device, the present invention can achieve precise control of the moving direction, speed and position of the first positioning magnet and the cleaning ball by accurately controlling the direction, flow rate and pressure of the liquid injected into the first conduit and the second conduit by the liquid pump. On the other hand, it can be applicable to delivery pipes of different shapes and lengths, thereby increasing the application scenarios of the present invention.

At this time, if the staff drives the cleaning ball to move in the conveying pipe through the first positioning magnet, then after the cleaning ball cleans up the single-walled tubes adsorbed on the inner wall of the conveying pipe, the cleaned single-walled tubes will flow directly with the airflow and finally fall directly out of the first discharge port. Through the above technical solution, the present invention can clean the inner wall of the conveying pipe while blowing the cleaned single-walled tubes out of the first discharge port, thereby effectively avoiding too many single-walled tubes adsorbed on the inner wall of the conveying pipe, and preventing too many single-walled tubes from accumulating in front of the cleaning ball when cleaning the inner wall of the conveying pipe, affecting the movement of the cleaning ball in the conveying pipe.

[0015] Furthermore, a battery and an annular magnet are provided in the cavity, the annular magnet is aligned with the movable ring, one end of the movable ring close to the annular magnet is a ferromagnetic material, the annular magnet is connected to the working shaft of the rotating motor through a bracket, the present invention supplies energy to the rotating motor through the battery, the annular magnet magnetically attracts the movable ring to ensure that the annular magnet and the movable ring can rotate synchronously, and in the process of cleaning the conveying pipe according to the present invention, the cleaning ball has two working states, the first working state: when the staff drives the cleaning ball to move in the conveying pipe through the first positioning magnet, the first through hole is aligned with the second through hole through the rotating motor, and the air is pumped to the airtight seal by the external air pump. A group of airflow is transmitted in the end cap. After the cleaning ball cleans the single-walled tubes adsorbed on the inner wall of the conveying pipe, the cleaned single-walled tubes will flow directly with the airflow and finally fall out directly from the first discharge port. In the first working state, it can effectively avoid too many single-walled tubes adsorbed on the inner wall of the conveying pipe. In the second working state: when the staff drives the cleaning ball to move in the conveying pipe through the first positioning magnet, the rotating motor can be continuously turned on to rotate the annular magnet and the movable ring. The movable ring is used to clean the single-walled tubes adsorbed on the inner wall of the conveying pipe. In the second working state, the cleaning ball can rotate and rub the inner wall of the single-walled tube to improve the cleaning effect.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] Compared with the existing single-wall tube conveying device, the present invention is provided with a flexible packaging mechanism and a blanking mechanism. Through the cooperation of the flexible packaging mechanism and the blanking mechanism, precise quantitative control of the single-wall tube packaging process is achieved, which greatly improves the packaging quality and accuracy. During the packaging process, the flexible packaging mechanism can accurately control the discharge amount of the single-wall tubes on the one hand, and quickly switch between the packaging forms of packaging bags and packaging bottles through simple operations on the other hand, which significantly improves the overall production efficiency. The blanking mechanism has an excess recovery function. If the single-wall tubes falling into the packaging container exceed the rated weight due to misoperation or other reasons, the excess single-wall tubes can be automatically recovered and reused through the blanking mechanism, further reducing the weight error and reducing the trouble of manual processing.

[0018] 2. The present invention is further provided with a cleaning ball and a first positioning magnet. By controlling the movement of the first positioning magnet in the positioning frame, the cleaning ball can be driven to move synchronously in the delivery pipe.

Compared with the current technical solutions for cleaning the delivery pipe of a single-walled tube delivery device, the present invention, on the one hand, can achieve precise control of the moving direction, speed and position of the first positioning magnet and the cleaning ball by accurately controlling the direction, flow rate and pressure of the liquid injected into the first conduit and the second conduit by the liquid pump. On the other hand, it can be applied to delivery pipes of different shapes and lengths, thereby increasing the application scenarios of the present invention.

[0019] 3. The cleaning ball of the present invention is designed with multiple working modes. When the conveying pipe needs to be cleaned, the first through hole inside the cleaning ball is aligned with the second through hole by turning on the rotating motor, and the external air pump is used to deliver airflow into the sealed end cap. While the cleaning ball cleans the inner wall of the conveying pipe, the cleaned single-walled tubes will directly fall out of the first discharge port with the airflow, achieving efficient cleaning and discharge operations, preventing excessive accumulation of single-walled tubes in front of the cleaning ball that affects its movement, and improving cleaning efficiency. At the same time, the cleaning ball also has a rotating friction working state. The rotating motor drives the annular magnet and the movable ring to rotate, and the movable ring is used to perform rotational friction cleaning on the inner wall of the conveying pipe, further enhancing the cleaning effect and ensuring that the conveying pipe is thoroughly cleaned.

When the present invention is working, the single-wall tube produced by the single-wall tube preparation equipment will enter the storage tank 1 along the conveying mechanism 2 and the feed valve 11 (the method of the single-wall tube flowing into the storage tank 1 belongs to the conventional technical means in this field, and the specific structure and implementation are as follows. The present method is not described), the produced single-walled tubes are temporarily stored in the storage tank 1. When the staff needs to package the single-walled tubes in the storage tank 1, the staff can place the packaging bag or packaging bottle into the flexible packaging mechanism, and then open the discharge valve 12. At this time, the single-walled tube will fall into the packaging bag or packaging bottle along the blanking mechanism, and the packaging bag or packaging bottle will be quantitatively packaged by the flexible packaging mechanism. Finally, compared with the current single-walled tube conveying device, the blanking mechanism in the present invention has an excess recovery function. When the single-walled tubes falling into the packaging bag or packaging bottle exceed the rated amount due to various reasons such as misoperation, the staff can suck the excess single-walled tubes out of the packaging bag or packaging bottle through the blanking mechanism to ensure that the weight of the packaged single-walled tubes meets the standard.

[0035] like Figure 2-Figure 3 As shown, the flexible packaging mechanism includes a packaging box 32 and two movable frames 331. The two movable frames 331 are relatively arranged at the upper ends of the packaging box 32. Each movable frame 331 is connected to the vacuum box 3 through a group of third cylinders 33. The two groups of third cylinders 33 are used to control the two movable frames 331 to move closer to and farther away from each other. A vacuum suction cup and a hot pressing plate are provided in each movable frame 331. A placement frame 324 and a mounting frame 326 are provided in the packaging box 32. Bottle caps are provided on the placement frame 324. The mounting frame 326 is connected to the vacuum box 3 through a linear motor 323. A clamp is provided below the mounting frame 326. A second cylinder 325 is provided above the mounting frame 326. The movement of the clamp is controlled by the second cylinder 325.

[0036] like Figure 2-Figure 3 As shown, the flexible packaging mechanism also includes a base 321 and a lifting seat 322. The base 321 and the lifting seat 322 are connected through a lifting module. A weighing plate 3221 is provided at the upper end of the lifting seat 322. The weighing plate 3221 and the lifting seat 322 are connected through a piezoelectric element and a compression spring.

[0037] When the single-walled tubes in the storage tank 1 are to be packaged into a packaging bag, the staff can fix the upper ends of the packaging bag with the vacuum suction cups in the two movable frames 331, and then open the lifting module to make the lifting seat 322 and the weighing plate 3221 rise until the packaging bag is in a relaxed state. At this time, the discharge valve 12 is opened, and the single-walled tubes will fall into the packaging bag along the blanking mechanism. The staff can know the weight of the single-walled tubes falling into the packaging bag by detecting the electrical signal generated by the piezoelectric element. When the single-walled tubes falling into the packaging bag reach the rated amount, the staff can close the discharge valve 12, and then make the two movable frames 331 close to each other through the two sets of third cylinders 33, and open the hot pressing plate to heat-seal the packaging bag through the hot pressing plate. When the single-walled tubes in the storage tank 1 are to be packaged into a packaging bottle, the staff The packaging bottle can be directly placed on the weighing plate 3221, and then the discharge valve 12 is opened. At this time, the single-walled tube will fall into the packaging bottle along the blanking mechanism. Similarly, the staff can know the weight of the single-walled tube falling into the packaging bottle by detecting the electrical signal generated by the piezoelectric element. When the single-walled tube falling into the packaging bottle reaches the rated amount, the staff can close the discharge valve 12, and then clamp the bottle cap set on the placement rack 324 with the clamping claw, and then place the bottle cap into the packaging bottle through the cooperation of the linear motor 323 and the second cylinder 325. Compared with the current single-walled tube conveying device, the present invention can, on the one hand, quickly switch between the two packaging forms of packaging bags and packaging bottles through simple operations, thereby significantly improving the overall production efficiency. On the other hand, it can detect the weight of the single-walled tube falling into the packaging bottle or packaging bag in real time, thereby greatly improving the packaging accuracy.

[0038] like Figure 4-Figure 5 As shown, the blanking mechanism includes a blanking funnel 31, a first cylinder 311 and a telescopic cylinder 312. The telescopic cylinder 312 is arranged on the outer side of the lower end of the blanking funnel 31. The first cylinder 311 is arranged on the blanking funnel 31. The working end of the first cylinder 311 is connected to the telescopic cylinder 312. The telescopic cylinder 312 is controlled by the first cylinder 311 to perform a lifting movement on the outer side of the lower end of the blanking funnel 31, so that when the single-walled tube is transported to the packaging bottle or packaging bag, the telescopic cylinder 312 can be extended into the packaging bottle or packaging bag, thereby reducing the risk of the single-walled tube splashing.

[0039] like Figure 4-Figure 5As shown, the interior of the telescopic cylinder 312 is provided with a guide groove 3121, and a filter screen 3122 is provided at the middle position of the guide groove 3121. The upper end of the guide groove 3121 is connected to the external suction fan through a hose, and the lower end area of ​​the guide groove 3121 is provided with an arc structure. During the packaging process of the present invention, if it is detected that the single-walled tubes falling into the packaging bag or packaging bottle exceed the rated weight, the staff can turn on the external fan to generate a set of suction force through the external fan. At this time, the excess single-walled tubes in the packaging bag or packaging bottle will be sucked into the guide groove 3121 and intercepted by the filter screen 3122. When the external fan is turned off, the single-walled tubes intercepted by the filter screen 3122 will fall into The arc-shaped area at the lower end of the guide groove 3121 serves to cache the single-wall tubes. Through the above technical solution, the present invention further ensures the accuracy of single-wall tube packaging. When the staff puts a new packaging bag or packaging bottle under the blanking mechanism, the staff can first turn on the external fan to generate a set of blowing force through the external fan, so that the single-wall tubes cached in the arc-shaped area at the lower end of the guide groove 3121 and the single-wall tubes remaining on the filter 3122 flow with the air into the new packaging bag or packaging bottle. Compared with the current single-wall tube conveying device, the present invention can automatically recycle excess single-wall tubes, further reduce the weight error, and reduce the trouble of manual processing.

[0040] like Figure 6-Figure 12 As shown, the conveying mechanism 2 includes a positioning frame 21 and a conveying pipe 22. The positioning frame 21 is arranged above the conveying pipe 22. A first positioning magnet 213 is arranged inside the positioning frame 21. The conveying pipe 22 is connected to the single-walled pipe preparation equipment through the feed port 222. The conveying pipe 22 is connected to the feed valve 11 through the second discharge port 224. A cleaning ball 223 is arranged at one end of the conveying pipe 22 near the second discharge port 224. A second positioning magnet 2231 is arranged on the upper end of the cleaning ball 223. The first positioning magnet 213 and the second positioning magnet 2231 are aligned and attracted to each other. The diameter of the cleaning ball 223 is larger than the diameter of the second discharge port 224. In the process of conveying the single-walled tube, the single-walled tube flows along the feed port 222, the conveying tube 22, the second discharge port 224, and the feed valve 11 into the storage tank 1. When the single-walled tube conveying work is completed, the present invention can close the feed valve 11 and the outlet end of the single-walled tube preparation equipment. At this time, the staff can indirectly drive the cleaning ball 223 to move synchronously in the conveying tube 22 by controlling the first positioning magnet 213 to move in the positioning frame 21. During the movement of the cleaning ball 223, the conveying tube 22 can be cleaned by the cleaning ball 223 to avoid some single-walled tubes from being adsorbed on the inner wall of the conveying tube 22 due to static electricity and other reasons, causing blockage.

[0041] like Figure 6-Figure 7 、 Figure 12As shown, a sealing end cover 23 is provided at one end of the conveying pipe 22 near the second discharge port 224, and a first discharge port 221 is provided at one end of the conveying pipe 22 near the feed port 222. A sealing plug 2211 is provided inside the first discharge port 221, and the sealing plug 2211 is flush with the inner wall of the conveying pipe 22 near the end of the conveying pipe 22. The present invention ensures that during the process of conveying the single-walled tube, the single-walled tube can flow smoothly through the first discharge port 221 through the sealing plug 2211. When the cleaning ball 223 cleans the single-walled tube adsorbed on the inner wall of the conveying tube 22 to the first discharge port 221, the staff can remove the sealing plug 2211 from the first discharge port 221 to discharge the single-walled tube from the conveying pipe 22.

[0042] like Figure 6-Figure 8 、 Figure 12 As shown, the two ends of the positioning frame 21 are respectively provided with a first conduit 211 and a second conduit 212. The first conduit 211 is provided at one end of the positioning frame 21 close to the sealing end cover 23, and the second conduit 212 is provided at one end of the positioning frame 21 close to the first discharge port 221. The first conduit 211 and the second conduit are both connected to an external liquid pump. In the process of cleaning the inner wall of the delivery pipe 22 of the present invention, the staff can inject liquid into the first conduit 211 through the external liquid pump. At this time, the pressure at one end of the positioning frame 21 close to the sealing end cover 23 increases rapidly. In the closed space of the positioning frame 21, this part of the pressure will act on the side of the first positioning magnet 213 close to the first conduit 211. Under the action of the hydraulic pressure, the first positioning magnet 213 will The cleaning ball 223 is moved along the positioning frame 21 toward the second conduit 212, and the first positioning magnet 213 drives the cleaning ball 223 to move synchronously in the delivery pipe 22 during the movement to achieve the purpose of cleaning the delivery pipe 22. When the delivery pipe 22 is cleaned and the first positioning magnet 213 and the cleaning ball 223 need to be reset, the staff can inject liquid into the second conduit 212 through an external liquid pump. At the same time, the first conduit 211 serves as a liquid return channel. At this time, under the action of the hydraulic pressure, the first positioning magnet 213 and the cleaning ball 223 will be reset to the initial position for subsequent use. Compared with the current technical solution for cleaning the delivery pipe 22 of the single-walled tube delivery device, the present invention can, on the one hand, achieve precise control of the moving direction, speed and position of the first positioning magnet 213 and the cleaning ball 223 by accurately controlling the direction, flow rate and pressure of the liquid pump injected into the first conduit 211 and the second conduit 212. On the other hand, it can be applicable to delivery pipes 22 of different shapes and lengths, thereby increasing the application scenarios of the present invention.

[0043] like Figure 7-11As shown, the sealing end cover 23 is connected to the external air pump, a movable ring 2233 is provided at the middle position of the cleaning ball 223, a cavity is provided inside the cleaning ball 223, a first through hole 2235 is provided at the end of the cavity away from the sealing end cover 23, a rotating motor 2232 and a fixing bracket 2238 are provided at the end of the cavity close to the sealing end cover 23, the rotating motor 2232 is connected to the cleaning ball 223 through the fixing bracket 2238, and the working shaft of the rotating motor 2232 is close to the first through hole 2235. A sealing plate 2236 is provided at one end, and a second through hole 22361 is provided on the sealing plate 2236. The first through hole 2235 is adapted to the second through hole 22361. In the process of conveying the single-walled tube, the first through hole 2235 and the second through hole 22361 are staggered with each other, and the sealing plate 2236 is used to prevent the single-walled tube from entering the first through hole 2235 and entering the cavity inside the cleaning ball 223, thereby ensuring that the single-walled tube completely flows out from the second discharge port 224. When the present invention needs to clean the conveying When the pipe 22 is opened, the staff can start the rotating motor 2232 to align the first through hole 2235 with the second through hole 22361, then start the external air pump and take the sealing plug 2211 out of the first discharge port 221, and send a set of air flow into the sealing end cover 23 through the external air pump. At this time, if the staff drives the cleaning ball 223 to move in the conveying pipe 22 through the first positioning magnet 213, the cleaning ball 223 will be removed after cleaning the single-walled tube adsorbed on the inner wall of the conveying pipe 22. The cleaned single-walled tubes will flow directly with the air flow and finally fall directly out of the first discharge port 221. Through the above technical solution, the present invention can clean the inner wall of the conveying pipe 22 while blowing the cleaned and fallen single-walled tubes out of the first discharge port 221, thereby effectively avoiding too many single-walled tubes adsorbed on the inner wall of the conveying pipe 22, and preventing too many single-walled tubes from accumulating in front of the cleaning ball 223 when the cleaning ball 223 is cleaning the inner wall of the conveying pipe 22, thereby affecting the movement of the cleaning ball 223 in the conveying pipe 22.

[0044] like Figure 7-11As shown, a battery 2234 and an annular magnet 2237 are also provided in the cavity. The annular magnet 2237 is aligned with the movable ring 2233. The end of the movable ring 2233 close to the annular magnet 2237 is made of ferromagnetic material. The annular magnet 2237 is connected to the working shaft of the rotating motor 2232 through a bracket. The present invention supplies energy to the rotating motor 2232 through the battery 2234. The annular magnet 2237 magnetically attracts the movable ring 2233 to ensure that the annular magnet 2237 and the movable ring 2233 can rotate synchronously. In the process of cleaning the conveying pipe 22 of the present invention, the cleaning ball 223 has two working states. In the first working state: when the staff drives the cleaning ball 223 to move in the conveying pipe 22 through the first positioning magnet 213, the first through hole 2235 and the second through hole 2236 are moved by the rotating motor 2232. 1, a group of air flows into the sealing end cover 23 through an external air pump, and after the cleaning ball 223 cleans the single-walled tubes adsorbed on the inner wall of the conveying pipe 22, the cleaned single-walled tubes will flow directly with the air flow and finally fall directly out of the first discharge port 221. In the first working state, it can effectively avoid excessive single-walled tubes adsorbed on the inner wall of the conveying pipe 22. In the second working state: when the staff drives the cleaning ball 223 to move in the conveying pipe 22 through the first positioning magnet 213, the rotating motor 2232 can be continuously turned on, and the annular magnet 2237 and the movable ring 2233 are rotated by the rotating motor 2232, and the single-walled tubes adsorbed on the inner wall of the conveying pipe 22 are cleaned through the movable ring 2233. In the second working state, the cleaning ball 223 can rotate and rub the inner wall of the single-walled tube to improve the cleaning effect.

[0045] The working principle of the present invention is as follows: in the process of conveying single-walled tubes, the single-walled tubes flow into the storage tank 1 along the feed port 222, the conveying pipe 22, the second discharge port 224, and the feed valve 11. When the staff needs to package the single-walled tubes in the storage tank 1, the staff can place the packaging bag or packaging bottle into the flexible packaging mechanism, and then open the discharge valve 12. At this time, the single-walled tubes in the storage tank 1 will fall into the packaging bag or packaging bottle along the blanking mechanism, and the packaging bag or packaging bottle will be quantitatively packaged by the flexible packaging mechanism. During the packaging process, if it is detected that the single-walled tubes falling into the packaging bag or packaging bottle exceed the rated weight, the staff can turn on the external fan. , a set of suction is generated by the external fan to suck the excess single-walled tubes in the packaging bag or bottle into the guide groove 3121 and be intercepted by the filter screen 3122. When the external fan is turned off, the single-walled tubes intercepted by the filter screen 3122 will fall into the arc-shaped area at the lower end of the guide groove 3121, thereby caching the single-walled tubes. When the single-walled tube conveying work is completed, the present invention can close the feed valve 11 and the outlet end of the single-walled tube preparation equipment. At this time, the staff drives the cleaning ball 223 to move synchronously in the conveying pipe 22 through the first positioning magnet 213. During the movement of the cleaning ball 223, the conveying pipe 22 can be cleaned by the cleaning ball 223.
