Description

Technical Field

[0001] The present invention relates to the technical field of single-wall tube transportation, and specifically, it is a single-wall tube transportation device with a flexible packaging function. Background Art

[0002] Single-wall tubes, also known as single-wall carbon nanotubes, with their nanoscale diameters, excellent mechanical strength, and outstanding electrical properties, have become ideal materials for constructing next-generation microelectronic devices. However, in the transportation and packaging processes of single-wall tubes, due to the special physical properties of single-wall tubes, they are easily adsorbed on the inner wall of the transportation tube.

[0003] Currently, in order to ensure the efficiency of single-wall tube transportation, a cleaning mechanism is usually set inside the transportation pipeline. For example, the patents "CN221116025U A device for transporting carbon nanotube powder" and "CN119262848A A single-wall carbon nanotube powder transportation device" respectively disclose a technical solution for cleaning the transportation pipeline. However, the existing technology has certain limitations. In actual working scenarios, the transportation pipeline is usually very long and has many curved ends. The current cleaning methods are difficult to adapt to transportation pipelines of different shapes and lengths, and basically only friction the inner wall of the pipeline unidirectionally, unable to perform rotational friction or reciprocating friction on the inner wall of the pipeline, resulting in difficult-to-guarantee cleaning effects. Finally, in terms of packaging forms, traditional devices usually can only be designed for a single packaging form, such as only applicable to packaging bag packaging or only applicable to packaging bottle packaging. When market demands change and enterprises are difficult to quickly switch packaging forms, it is not conducive to improving work efficiency. On the other hand, currently, if it is found that the amount of single-wall tubes falling in during the packaging process exceeds the rated weight, traditional devices usually lack an effective excess recycling mechanism and cannot recycle and reuse the excess single-wall tubes. Summary of the Invention

[0004] The purpose of the present invention is to provide a single-wall tube transportation device with a flexible packaging function to solve the problems raised in the existing technology.

[0005] To achieve the above object, the present invention provides the following technical solution: 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. Feed valves and discharge valves are respectively arranged at the upper and lower ends of the storage tank. 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 manufacturing equipment. A blanking mechanism is arranged at the top of the vacuum box, the blanking mechanism is connected to the discharge valve, and a flexible packaging mechanism is arranged below the blanking mechanism. When the present invention is working, the single-wall tubes produced by the single-wall tube manufacturing equipment will enter the storage tank along the conveying mechanism and the feed valve (the method of the single-wall tubes flowing into the storage tank belongs to the conventional technical means in the art, and the specific structure and implementation method will not be described). The produced single-wall tubes are temporarily stored by the storage tank. When the staff needs to package the single-wall tubes in the storage tank, the staff can place a packaging bag or a packaging bottle into the flexible packaging mechanism, and then open the discharge valve. At this time, the single-wall tubes will fall into the packaging bag or the packaging bottle along the blanking mechanism, and the flexible packaging mechanism performs quantitative packaging on the packaging bag or the packaging bottle. Finally, compared with the current single-wall tube conveying device, the blanking mechanism in the present invention has an over-quantity recovery function. When the single-wall tubes falling into the packaging bag or the packaging bottle exceed the specified quantity due to various reasons such as misoperation, the staff can suck out the excess single-wall tubes from the packaging bag or the packaging bottle through the blanking mechanism to ensure that the weight of the packaged single-wall tubes meets the standard.

[0006] Further, the flexible packaging mechanism includes a packaging box and two movable frames. The two movable frames are relatively arranged at the upper two ends of the packaging box. Each movable frame is connected to the vacuum box through a set of third cylinders. The two movable frames are controlled to approach and separate from each other by two sets of third cylinders. A vacuum suction cup and a hot pressing plate are arranged in each movable frame. A placing rack and a mounting rack are arranged in the packaging box. A bottle cap is arranged on the placing rack. The mounting rack is connected to the vacuum box through a linear motor. A clamping jaw is arranged below the mounting rack, and a second cylinder is arranged above the mounting rack. The clamping jaw is controlled to move by the second cylinder.

[0007] Further, the flexible packaging mechanism further includes a base and a lifting seat. The base and the lifting seat are connected through a lifting module. A weighing plate is arranged at the upper end inside the lifting seat. The weighing plate is connected to the lifting seat through a piezoelectric element and a compression spring.

[0008] When the single-wall tube in the storage tank needs to be packaged into a packaging bag, the staff can use the vacuum suction cups in the two movable frames to suck and fix the two sides of the upper end of the packaging bag. Then, the lifting module is activated, and the lifting seat and the weighing plate are lifted through the lifting module until the packaging bag is in a relaxed state. At this time, the discharge valve is opened, and the single-wall tube will fall into the packaging bag along the blanking mechanism. The staff can know the weight of the single-wall tube falling into the packaging bag by detecting the electrical signal generated by the piezoelectric element. When the single-wall tube falling into the packaging bag reaches the rated amount, the staff can close the discharge valve, and then make the two movable frames approach each other through two groups of third cylinders, and activate the hot pressing plate to heat-seal the packaging bag; when the single-wall tube in the storage tank needs to be packaged into a packaging bottle, the staff can directly place the packaging bottle on the weighing plate and then open the discharge valve. At this time, the single-wall tube will fall into the packaging bottle along the blanking mechanism. Similarly, the staff can know the weight of the single-wall tube falling into the packaging bottle by detecting the electrical signal generated by the piezoelectric element. When the single-wall tube falling into the packaging bottle reaches the rated amount, the staff can close the discharge valve, then clamp the bottle cap arranged on the placing rack through the gripper, 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-wall tube conveying device, the present invention can quickly switch between the two packaging forms of the packaging bag and the packaging bottle through simple operations on the one hand, significantly improving the overall production efficiency, and on the other hand, can detect the weight of the single-wall tube falling into the packaging bottle or the packaging bag in real time, thus greatly improving the packaging accuracy.

[0009] Further, the blanking mechanism includes a blanking funnel, a first cylinder, and a telescopic cylinder. The telescopic cylinder is arranged outside the lower end of the blanking funnel. The first cylinder is arranged on the blanking funnel, and the working end of the first cylinder is connected to the telescopic cylinder. The telescopic cylinder is controlled by the first cylinder to move up and down outside the lower end of the blanking funnel, so as to facilitate the telescopic cylinder to extend into the packaging bottle or the packaging bag when the single-wall tube is conveyed into the packaging bottle or the packaging bag, reducing the risk of the single-wall tube splashing.

[0010] Furthermore, a guide groove is provided inside the telescopic cylinder. A filter screen is provided at the middle position of the guide groove. The upper end of the guide groove is connected to an external suction fan through a hose. An arc-shaped structure is provided in the lower end area of the guide groove. During the packaging process of the present invention, if it is detected that the single-wall pipe falling into the packaging bag or packaging bottle exceeds the rated weight, the staff can turn on the external fan to generate a set of suction force. At this time, the excessive single-wall pipes in the packaging bag or packaging bottle will be sucked into the guide groove and intercepted by the filter screen. When the external fan is turned off, the single-wall pipes intercepted by the filter screen will fall into the arc-shaped area at the lower end of the guide groove, so as to achieve the purpose of caching the single-wall pipes. Through the above technical solution, the present invention further ensures the packaging accuracy of the single-wall pipe. 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, so that the single-wall pipes cached in the arc-shaped area at the lower end of the guide groove and the single-wall pipes remaining on the filter screen flow into the new packaging bag or packaging bottle along with the air flow. Compared with the current single-wall pipe conveying device, the present invention can automatically recycle the excessive single-wall pipes, further reduce the weight error, and reduce the trouble of manual handling.

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

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

[0013] Further, a first conduit and a second conduit are respectively arranged at both ends of the positioning frame. The first conduit is arranged at one end of the positioning frame close to the sealing end cover, and the second conduit is arranged at one end of the positioning frame close to the first discharge port. Both the first conduit and the second conduit are connected to an external liquid pump. During the cleaning process of the inner wall of the conveying pipe in the present invention, the staff can inject liquid into the first conduit through the external liquid pump. At this time, the pressure at one end of the positioning frame close to the sealing end cover rapidly increases. In the enclosed space of the positioning frame, this part of the pressure will act on one 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 in the direction of the second conduit. During the movement of the first positioning magnet, it will drive the cleaning ball to move synchronously in the conveying pipe to achieve the purpose of cleaning the conveying pipe. When the cleaning of the conveying 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 the external liquid pump, and 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 reset to the initial position for subsequent use. Compared with the technical solution of cleaning the conveying pipe of the current single-wall pipe conveying device, on the one hand, by precisely controlling the direction, flow rate, and pressure of the liquid pump injecting liquid into the first conduit and the second conduit, the precise control of the moving direction, speed, and position of the first positioning magnet and the cleaning ball can be achieved. On the other hand, it can be applied to conveying pipes of different shapes and lengths, thereby increasing the application scenarios of the present invention.

[0014] Furthermore, the sealed end cap is connected to an external air pump. An activity ring is provided at the middle position of the cleaning ball. A cavity is provided inside the cleaning ball. A first through hole is provided at one end of the cavity away from the sealed end cap. A rotary motor and a fixing bracket are provided at one end of the cavity close to the sealed end cap. The rotary motor is connected to the cleaning ball through the fixing bracket. A sealing plate is provided at one end of the working shaft of the rotary motor close to the first through hole. A second through hole is provided on the sealing plate. The first through hole is adapted to the second through hole. During the process of conveying the single-wall tube in the present invention, the first through hole and the second through hole are staggered from each other. The sealing plate is used to prevent the single-wall tube from entering the cavity inside the cleaning ball along the first through hole, ensuring that the single-wall tube completely flows out from the second discharge port. When the present invention needs to clean the conveying pipe, the staff can start the rotary motor to align the first through hole and the second through hole. Then, the external air pump is started and the sealing plug is taken out from the first discharge port. A stream of air is conveyed into the sealed end cap through the external air pump. At this time, if the staff drives the cleaning ball to move in the conveying pipe through the first positioning magnet, after the cleaning ball cleans the single-wall tube adsorbed on the inner wall of the conveying pipe, the cleaned single-wall tube will directly flow along with the air stream and finally directly fall out from 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-wall tube out of the first discharge port, effectively avoiding too many single-wall tubes adsorbed on the inner wall of the conveying pipe and preventing too many single-wall tubes from accumulating in front of the cleaning ball when the cleaning ball cleans the inner wall of the conveying pipe, which affects the movement of the cleaning ball in the conveying pipe.

[0015] Furthermore, a storage battery and an annular magnet are also provided in the cavity. The annular magnet is aligned with the activity ring. One end of the activity ring close to the annular magnet is made of ferromagnetic material. The annular magnet is connected to the working shaft of the rotary motor through a bracket. The present invention supplies energy to the rotary motor through the storage battery. The annular magnet magnetically attracts the activity ring to ensure that the annular magnet and the activity ring can rotate synchronously. During the process of cleaning the conveying pipe in 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 and the second through hole are aligned through the rotary motor. A stream of air is conveyed into the sealed end cap through the external air pump. After the cleaning ball cleans the single-wall tube adsorbed on the inner wall of the conveying pipe, the cleaned single-wall tube will directly flow along with the air stream and finally directly fall out from the first discharge port. In the first working state, it can effectively avoid too many single-wall tubes adsorbed on the inner wall of the conveying pipe. The second working state: When the staff drives the cleaning ball to move in the conveying pipe through the first positioning magnet, the rotary motor can be continuously started. The annular magnet and the activity ring are rotated through the rotary motor. The single-wall tube adsorbed on the inner wall of the conveying pipe is cleaned through the activity ring. In the second working state, the cleaning ball can rotate and rub the inner wall of the single-wall tube to improve the cleaning effect.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: Compared with the current single-wall pipe 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 pipe packaging process is achieved, greatly improving the packaging quality and accuracy. During the packaging process, on the one hand, the flexible packaging mechanism accurately controls the discharge amount of the single-wall pipe, and on the other hand, through simple operations, it can quickly switch between two packaging forms, namely, packaging bags and packaging bottles, significantly improving the overall production efficiency. The blanking mechanism has an overage recycling function. If the single-wall pipe falling into the packaging container exceeds the rated weight due to misoperation or other reasons, the overage single-wall pipe can be automatically recycled through the blanking mechanism, further reducing the weight error and reducing the trouble of manual handling; 2. The present invention is also provided with a cleaning ball and a first positioning magnet. By controlling the movement of the first positioning magnet within the positioning frame, the cleaning ball can be driven to move synchronously within the conveying pipe. During the movement of the cleaning ball, it can effectively remove the single-wall pipes adsorbed on the inner wall of the conveying pipe due to static electricity or other reasons, avoiding blockage phenomena and ensuring that the conveying pipe always remains unobstructed, providing a reliable guarantee for the subsequent conveying work of the single-wall pipe. Compared with the technical solutions for cleaning the conveying pipe of the current single-wall pipe conveying device, on the one hand, by precisely controlling the direction, flow rate, and pressure of the liquid injected by the liquid pump into the first conduit and the second conduit, precise control over the moving direction, speed, and position of the first positioning magnet and the cleaning ball can be achieved. On the other hand, it can be applied to conveying pipes of different shapes and lengths, thereby increasing the application scenarios of the present invention; 3. The cleaning ball in the present invention is designed with multiple working modes. When it is necessary to clean the conveying pipe, by turning on the rotating motor, the first through-hole inside the cleaning ball is aligned with the second through-hole, and in cooperation with an external air pump to convey air flow into the sealing end cover, while the cleaning ball cleans the inner wall of the conveying pipe, the single-wall pipes being cleaned will directly fall out from the first discharge port along with the air flow, achieving an efficient operation of cleaning and discharging at the same time, preventing excessive accumulation of single-wall pipes in front of the cleaning ball from affecting its movement and improving the cleaning efficiency. At the same time, the cleaning ball also has a working state of rotational friction. The rotating motor drives the annular magnet and the movable ring to rotate, and the inner wall of the conveying pipe is cleaned by rotational friction of the movable ring, further enhancing the cleaning effect and ensuring that the conveying pipe is thoroughly cleaned.

[0019] Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0020] Embodiment: As Figures 1-12As shown in the figure, the present invention provides a technical solution, a single-wall tube conveying device with a flexible packaging function. The single-wall tube conveying device includes a storage tank 1, a conveying mechanism 2, and a vacuum box 3. The upper and lower ends of the storage tank 1 are respectively provided with a feed valve 11 and a discharge valve 12. One end of the conveying mechanism 2 is connected to the feed valve 11, and the other end of the conveying mechanism 2 is connected to a single-wall tube manufacturing device. The top of the vacuum box 3 is provided with a blanking mechanism, which is connected to the discharge valve 12. A flexible packaging mechanism is arranged below the blanking mechanism. When the present invention works, the single-wall tubes produced by the single-wall tube manufacturing device will enter the storage tank 1 along the conveying mechanism 2 and the feed valve 11 (the method of the single-wall tubes flowing into the storage tank 1 belongs to the conventional technical means in the field, and the specific structure and implementation method will not be described). The storage tank 1 is used to temporarily store the produced single-wall tubes. When the staff needs to package the single-wall tubes in the storage tank 1, the staff can place a packaging bag or a packaging bottle into the flexible packaging mechanism, and then open the discharge valve 12. At this time, the single-wall tubes will fall into the packaging bag or the packaging bottle along the blanking mechanism, and the flexible packaging mechanism will perform quantitative packaging on the packaging bag or the packaging bottle. Finally, compared with the current single-wall tube conveying device, the blanking mechanism in the present invention has an over-recovery function. When the single-wall tubes falling into the packaging bag or the packaging bottle exceed the specified amount due to various reasons such as misoperation, the staff can suck out the excess single-wall tubes from the packaging bag or the packaging bottle through the blanking mechanism to ensure that the weight of the packaged single-wall tubes meets the standard.

[0021] As Figures 2-3 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 both sides of the packaging box 32. Each movable frame 331 is connected to the vacuum box 3 through a set of third cylinders 33. The two movable frames 331 are controlled to approach and move away from each other through the two sets of third cylinders 33. A vacuum suction cup and a hot pressing plate are arranged in each movable frame 331. A placing rack 324 and a mounting rack 326 are arranged in the packaging box 32. A bottle cap is arranged on the placing rack 324. The mounting rack 326 is connected to the vacuum box 3 through a linear motor 323. A clamping jaw is arranged below the mounting rack 326, and a second cylinder 325 is arranged above the mounting rack 326. The clamping jaw is controlled to move through the second cylinder 325.

[0022] As Figures 2-3 shown, the flexible packaging mechanism further 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 arranged at the upper end inside the lifting seat 322. The weighing plate 3221 is connected to the lifting seat 322 through piezoelectric elements and compression springs.

[0023] When the single-wall pipes in the storage tank 1 need to be packaged into a packaging bag, the staff can use the vacuum suckers in the two movable frames 331 to suck and fix the two sides of the upper end of the packaging bag. Then, the lifting module is activated, and the lifting seat 322 and the weighing plate 3221 are lifted through the lifting module until the packaging bag is in a slack state. At this time, the discharge valve 12 is opened, and the single-wall pipes will fall into the packaging bag along the blanking mechanism. The staff can know the weight of the single-wall pipes falling into the packaging bag by detecting the electrical signals generated by the piezoelectric elements. When the single-wall pipes 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 approach each other through the two groups of third cylinders 33, and activate the hot pressing plate to heat-seal the packaging bag through the hot pressing plate. When the single-wall pipes in the storage tank 1 need to be packaged into a packaging bottle, the staff can directly place the packaging bottle on the weighing plate 3221, and then open the discharge valve 12. At this time, the single-wall pipes will fall into the packaging bottle along the blanking mechanism. Similarly, the staff can know the weight of the single-wall pipes falling into the packaging bottle by detecting the electrical signals generated by the piezoelectric elements. When the single-wall pipes falling into the packaging bottle reach the rated amount, the staff can close the discharge valve 12, and then clamp the bottle cap provided on the placing rack 324 through the clamping jaws, 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-wall pipe conveying device, on the one hand, the present invention can quickly switch between the two packaging forms of packaging bags and packaging bottles through simple operations, significantly improving the overall production efficiency. On the other hand, it can detect the weight of the single-wall pipes falling into the packaging bottle or packaging bag in real time, thereby greatly improving the packaging accuracy. As Figures 4-5 shown, the blanking mechanism includes a blanking funnel 31, a first cylinder 311, and a telescopic cylinder 312. The telescopic cylinder 312 is arranged outside the lower end of the blanking funnel 31, and 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 motion outside the lower end of the blanking funnel 31, so as to facilitate the telescopic cylinder 312 to extend into the packaging bottle or packaging bag when the single-wall pipes are conveyed into the packaging bottle or packaging bag, reducing the risk of the single-wall pipes splashing.

[0024] As Figures 4-5As shown, a guide groove 3121 is provided inside the telescopic cylinder 312. 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 an external suction fan through a hose. An arc-shaped structure is provided in the lower end area of the guide groove 3121. During the encapsulation process of the present invention, if it is detected that the single-wall tube falling into the packaging bag or packaging bottle exceeds the rated weight, the staff can turn on the external fan to generate a set of suction force. At this time, the excessive single-wall 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-wall tubes intercepted by the filter screen 3122 will fall into the arc-shaped area at the lower end of the guide groove 3121, so as to achieve the purpose of caching the single-wall tubes. Through the above technical solution, the present invention further ensures the packaging accuracy of the single-wall tube. 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, 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 screen 3122 flow into the new packaging bag or packaging bottle along with the air flow. Compared with the current single-wall tube conveying device, the present invention can automatically recycle the excessive single-wall tubes, further reduce the weight error, and reduce the trouble of manual handling.

[0025] As Figures 6-12 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-wall tube preparation equipment through a feed port 222. The conveying pipe 22 is connected to the feed valve 11 through a second discharge port 224. A cleaning ball 223 is arranged at one end of the conveying pipe 22 close to the second discharge port 224. A second positioning magnet 2231 is arranged at the upper end of the cleaning ball 223. The first positioning magnet 213 is aligned with and attracts the second positioning magnet 2231. The diameter of the cleaning ball 223 is larger than the diameter of the second discharge port 224. During the process of conveying the single-wall tube in the present invention, the single-wall tube flows along the feed port 222, the conveying pipe 22, the second discharge port 224, and the feed valve 11 into the storage tank 1. When the single-wall tube conveying work is completed, the present invention can close the feed valve 11 and the outlet end of the single-wall tube preparation equipment. At this time, the staff can indirectly drive the cleaning ball 223 to move synchronously in the conveying pipe 22 by controlling the movement of the first positioning magnet 213 in the positioning frame 21. During the movement of the cleaning ball 223, the conveying pipe 22 can be cleaned by the cleaning ball 223, avoiding the phenomenon that some single-wall tubes are adsorbed on the inner wall of the conveying pipe 22 due to static electricity or other reasons, resulting in blockage.

[0026] As Figures 6-7 、 Figure 12As shown in the figure, a sealing end cap 23 is provided at one end of the conveying pipe 22 close to the second discharge port 224, and a first discharge port 221 is provided at one end of the conveying pipe 22 close to the feed port 222. A sealing plug 2211 is arranged inside the first discharge port 221. One end of the sealing plug 2211 close to the conveying pipe 22 is flush with the inner wall of the conveying pipe 22. In the present invention, through the sealing plug 2211, it is ensured that during the process of conveying the single-wall pipe, the single-wall pipe can smoothly flow through the first discharge port 221. When the cleaning ball 223 cleans the single-wall pipe adsorbed on the inner wall of the conveying pipe 22 to the first discharge port 221, the staff can take out the sealing plug 2211 from the first discharge port 221 to discharge the single-wall pipe from the conveying pipe 22.

[0027] As Figures 6-8 , Figure 12 shown in the figure, first conduits 211 and second conduits 212 are respectively arranged at both ends of the positioning frame 21. The first conduit 211 is arranged at one end of the positioning frame 21 close to the sealing end cap 23, and the second conduit 212 is arranged at one end of the positioning frame 21 close to the first discharge port 221. Both the first conduit 211 and the second conduit are connected to an external liquid pump. During the process of cleaning the inner wall of the conveying pipe 22 in 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 cap 23 rises rapidly. In the enclosed space of the positioning frame 21, this part of the pressure will act on one 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 move along the positioning frame 21 in the direction of the second conduit 212. During the movement of the first positioning magnet 213, the cleaning ball 223 will be driven to move synchronously in the conveying pipe 22 to achieve the purpose of cleaning the conveying pipe 22. When the cleaning of the conveying pipe 22 is completed 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 the 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 reset to the initial position for subsequent use. Compared with the technical solution for cleaning the conveying pipe 22 of the current single-wall pipe conveying device, on the one hand, by precisely controlling the direction, flow rate and pressure of the liquid injected by the liquid pump into the first conduit 211 and the second conduit 212, the precise control of the moving direction, speed and position of the first positioning magnet 213 and the cleaning ball 223 can be achieved. On the other hand, it can be applied to conveying pipes 22 of different shapes and lengths, thereby increasing the application scenarios of the present invention.

[0028] As Figures 7-11As shown, the sealed end cap 23 is connected to an external air pump. An activity 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 one end of the cavity away from the sealed end cap 23. A rotating motor 2232 and a fixing bracket 2238 are provided at one end of the cavity close to the sealed end cap 23. The rotating motor 2232 is connected to the cleaning ball 223 through the fixing bracket 2238. A sealing plate 2236 is provided at one end of the working shaft of the rotating motor 2232 close to the first through hole 2235. 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. During the process of conveying the single-wall tube in the present invention, the first through hole 2235 and the second through hole 22361 are staggered from each other. The sealing plate 2236 is used to prevent the single-wall tube from entering the cavity inside the cleaning ball 223 along the first through hole 2235, ensuring that the single-wall tube completely flows out from the second discharge port 224. When the present invention needs to clean the conveying pipe 22, the staff can start the rotating motor 2232 to align the first through hole 2235 with the second through hole 22361. Then, the external air pump is started and the sealing plug 2211 is taken out from the first discharge port 221. A group of airflows are conveyed into the sealed end cap 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, after the cleaning ball 223 cleans the single-wall tube adsorbed on the inner wall of the conveying pipe 22, the cleaned single-wall tube will directly flow with the airflow and finally directly fall out from 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-wall tube out of the first discharge port 221, thus effectively avoiding too many single-wall tubes adsorbed on the inner wall of the conveying pipe 22 and preventing too many single-wall tubes from accumulating in front of the cleaning ball 223 when the cleaning ball 223 cleans the inner wall of the conveying pipe 22, which affects the movement of the cleaning ball 223 in the conveying pipe 22.

[0029] As Figures 7-11As shown, a storage battery 2234 and an annular magnet 2237 are further arranged in the cavity. The annular magnet 2237 is aligned with the movable ring 2233. One 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 rotary motor 2232 through a bracket. In the present invention, the storage battery 2234 supplies energy to the rotary motor 2232, and 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. During the cleaning process of the conveying pipe 22 in the present invention, the cleaning ball 223 has two working states. 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 is aligned with the second through hole 22361 through the rotary motor 2232, and a group of airflows are conveyed into the sealing end cover 23 through an external air pump. After the cleaning ball 223 clears the single-wall pipes adsorbed on the inner wall of the conveying pipe 22, the cleared single-wall pipes will directly flow with the airflows and finally fall out directly from the first discharge port 221. In the first working state, it can effectively prevent excessive single-wall pipes adsorbed on the inner wall of the conveying pipe 22. 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 rotary motor 2232 can be continuously turned on. The annular magnet 2237 and the movable ring 2233 are rotated through the rotary motor 2232, and the single-wall pipes adsorbed on the inner wall of the conveying pipe 22 are cleaned by the movable ring 2233. In the second working state, the cleaning ball 223 can rotate and rub the inner wall of the single-wall pipe to improve the cleaning effect.

[0030] Working principle of the present invention: During the process of conveying the single-wall pipe, the single-wall pipe flows into the storage tank 1 along the feed inlet 222, the conveying pipe 22, the second discharge port 224, and the feed valve 11. When the staff needs to package the single-wall pipe 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-wall pipe in the storage tank 1 will fall into the packaging bag or packaging bottle along the blanking mechanism, and the flexible packaging mechanism is used to quantitatively package the packaging bag or packaging bottle. During the packaging process, if it is detected that the single-wall pipe falling into the packaging bag or packaging bottle exceeds the rated weight, the staff can turn on the external fan, and a set of suction force is generated by the external fan so that the excessive single-wall pipe in the packaging bag or packaging bottle is sucked into the guide groove 3121 and intercepted by the filter screen 3122. When the external fan is turned off, the single-wall pipe intercepted by the filter screen 3122 will fall into the lower arc area of the guide groove 3121, so as to achieve the purpose of caching the single-wall pipe. After the single-wall pipe conveying work is completed, the present invention can close the feed valve 11 and the outlet end of the single-wall pipe 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.
