Description

Technical Field

[0001] This invention relates to the field of tubular material conveying technology, and in particular to an automatic tubular material handling and conveying device. Background Technology

[0002] In the automated production of tubular materials, after extrusion molding and slitting, the tubular materials need to be conveyed in an orderly manner to the subsequent packaging equipment. To achieve continuous production, efficient conveying and automatic tubing handling devices must be set up between upstream and downstream processes to ensure the stability and rhythm matching of material flow, reduce manual intervention, and improve the overall automation level of the production line.

[0003] Currently, there are two main methods for conveying tubular materials from the manufacturing process to the packaging process. One is manual handling, where operators manually carry stacks of tubular materials into the packaging machine hopper, relying on manual labor for loading and stacking. The other method uses a simple belt conveyor to transport the tubular materials from the previous workstation to the packaging station. However, manual assistance is still needed in stages such as loading, sorting, sequencing, alignment, and directional feeding, and continuous manual intervention is also required during the subsequent packaging process.

[0004] Regarding the aforementioned technologies, firstly, manual conveying is inefficient, with frequent loading leading to wasted manpower, and manual contact can easily introduce the risk of secondary contamination. While simple conveying devices improve conveying efficiency, they lack automatic management functions, cannot effectively organize and position tubular materials, and are prone to problems such as jamming and uneven stacking, making it difficult to meet the needs of stable, continuous, and unmanned automated production. Summary of the Invention

[0005] In order to improve conveying efficiency and realize automatic tube handling, this application provides an automatic tube handling and conveying device for tubular materials.

[0006] This application provides an automatic tubular material handling and conveying device, which adopts the following technical solution: An automatic tubular material handling and conveying device includes a belt conveyor for receiving materials from the previous process, a material handling mechanism located at the output end of the belt conveyor, a turntable conveyor located at the output end of the material handling mechanism, and a discharge conveyor located at the output end of the turntable conveyor. The material handling mechanism includes a storage hopper fixedly connected to the output end of the belt conveyor and the input end of the turntable conveyor, a swing plate rotatably located on top of the storage hopper for handling the tubular material, a material handling roller rotatably located on top of the storage hopper for handling the tubular material, and a rotary drive for synchronously driving the swing plate and the material handling roller to rotate.

[0007] By adopting the above technical solution, a fully automated conveying chain from the previous process to the packaging process is constructed by setting up a belt conveyor, a material handling mechanism, a turntable conveyor, and a discharge conveyor in sequence. At the same time, the material handling mechanism adopts a structure that combines a swing plate and a material handling roller and is synchronously driven by the same rotating drive component. This enables efficient double tube handling before tubular materials enter the turntable conveyor, effectively avoiding the accumulation and bridging of tubular materials at the top of the storage hopper. This solves the problems of low efficiency of manual handling and the inability of simple conveying devices to automatically handle tubes in the existing technology, and provides a structural foundation for realizing unmanned continuous production.

[0008] Optionally, the turntable conveying mechanism includes a conveying connecting hopper fixedly connected to the storage hopper, a conveying turntable disposed in the conveying connecting hopper, a conveyor belt detachably disposed on the outer periphery of the conveying turntable, a limiting bracket disposed on the conveying connecting hopper and used to limit the tubular object, and a drive motor fixed on the outside of the conveying connecting hopper and used to drive the conveying turntable to rotate. The outer circumferential surface of the conveyor belt is continuously and uniformly provided with a plurality of tube grooves along the circumferential direction.

[0009] By adopting the above technical solution, a conveyor turntable with a conveyor belt is set up, and several tube grooves are continuously and evenly opened on the outer circumference of the conveyor belt. This allows tubular objects to be successively entered into the tube grooves as the conveyor belt rotates, achieving single-row and directional conveying of tubular objects. At the same time, the conveyor belt adopts a detachable structure, which facilitates quick replacement of the conveyor belt with the corresponding tube groove specification according to the diameter of the tubular object, significantly improving the versatility of the equipment.

[0010] Optionally, the top of the conveying hopper is further provided with a storage box for receiving tubular objects from the conveyor belt; the bottom of the storage box is provided with a receiving interface for the tubular objects to enter and a first notch for the discharge conveying mechanism to extend into; the side wall of the storage box is provided with a second notch communicating with the first notch.

[0011] By adopting the above technical solution, the storage box receives the tubular material from the conveyor belt, forming a temporary buffer zone to avoid material interruption caused by short pauses in downstream processes; the matching design of the receiving interface with the first and second notches provides a precise material picking position for the discharge conveying mechanism, ensuring that the tubular material can be smoothly taken out and transferred to the next process, thus improving the continuity and stability of the discharge process.

[0012] Optionally, the rotary drive includes a rotary motor fixed to the outside of the conveying hopper and whose output shaft is fixedly connected to one side of the material handling roller rotation shaft, a first gear fixed to the other side of the material handling roller rotation shaft, a second gear meshing with the first gear, an eccentric wheel fixed to the second gear, a connecting rod fixed to the output shaft of the eccentric wheel, and a connecting block with one end hinged to the connecting rod and the other end fixedly connected to the output shaft of the swing plate.

[0013] By adopting the above technical solution, the rotary motor drives the material feeding roller to rotate. Through the transmission mechanism composed of the first gear, the second gear, the eccentric wheel, the connecting rod and the connecting block, the continuous rotational motion is converted into the reciprocating oscillating motion of the oscillating plate. This realizes that a single drive source can drive the material feeding roller and the oscillating plate at the same time, which reduces equipment cost and energy consumption, while ensuring the synchronization and coordination of the two actions and improving the feeding effect.

[0014] Optionally, the discharge conveying mechanism includes a discharge bracket located near the output end of the turntable conveying mechanism, a horizontal linear module located on the discharge bracket, a horizontal mounting plate located at the output end of the horizontal linear module, a vertical linear module located on the horizontal mounting plate, and a discharge box located at the output end of the vertical linear module; the outer wall of the discharge box is also vertically provided with a conveying cylinder, and the output end of the conveying cylinder is provided with a conveying plate that cooperates with the first notch and the second notch.

[0015] By adopting the above technical solution, the discharge box is first moved above the storage box by the cooperation of the horizontal and vertical linear modules; then the conveying cylinder drives the conveying plate to extend into the first and second notches to smoothly remove the tubular material in the storage box and transfer it to the discharge box; then the tubular material in the discharge box is transferred to the next station by the cooperation of the horizontal and vertical linear modules. The whole process avoids manual intervention and improves the discharge efficiency.

[0016] Optionally, the belt conveyor is provided with a first electrostatic generator on the top of the side near the material handling mechanism, and the conveying connecting hopper is provided with a second electrostatic generator on the top of the limiting bracket.

[0017] By adopting the above technical solution, the first electrostatic device is installed at the top of the belt conveyor to eliminate the static electricity generated by friction during the conveying process of the tubular objects, and to prevent the tubular objects from adsorbing or sticking together; the second electrostatic device is installed at the top of the limiting bracket to eliminate the static electricity of the tubular objects during the conveying process of the turntable, to ensure that the tubular objects are stably positioned in the tube groove and fall smoothly into the storage box, effectively reducing the phenomenon of material jamming and disorder, and improving the conveying stability.

[0018] Optionally, a partition is provided on the side of the storage hopper near the swing plate, and an arc-shaped partition is also provided on the side of the partition near the material handling roller. The arc-shaped partition has an avoidance notch on the side facing the material handling roller. The bottom of the partition and the arc-shaped partition form a discharge gap for discharging tubular materials. A straightening connecting cloth for straightening tubular materials is also provided between the bottom of the swing plate and the top of the partition.

[0019] By adopting the above technical solution, the partition and the arc-shaped partition form a flow channel in the storage hopper, guiding the tubular material to concentrate towards the material-sorting roller; the clearance gap provides installation space for the material-sorting roller, and the discharge gap controls the discharge rate of the tubular material; the straightening connecting cloth connects the bottom of the swing plate and the top of the partition to prevent the tubular material from running out of the gap, and at the same time assists the tubular material to gradually straighten during the swing, improving the tube sorting effect and discharge uniformity.

[0020] Optionally, the outer circumference of the conveyor turntable is uniformly embedded with a plurality of strong magnetic blocks, and the inner side of the conveyor belt is provided with magnetic metal sheets that magnetically attract and cooperate with the strong magnetic blocks; the inner side of the conveyor belt is also provided with two guide protrusions along its length, and the outer circumference of the conveyor turntable is provided with guide grooves for the guide protrusions to slide and cooperate; both ends of the conveyor belt are provided with mutually cooperating locking buckles for detachable connection.

[0021] By adopting the above technical solution, the magnetic attraction between the strong magnetic block and the magnetic metal sheet, combined with the mechanical guidance of the guide convex strip and guide groove, and the detachable connection of the docking lock, enables the rapid installation, precise positioning, and reliable fixation of the conveyor belt on the conveyor turntable. This structure allows the conveyor belt to be replaced without tools, significantly shortening the changeover time and solving the problem that existing equipment is difficult to adapt to the production of tubular materials of different specifications. At the same time, it ensures the positional stability of the conveyor belt under high-speed operation.

[0022] Optionally, the conveyor connecting hopper is further provided with a cleaning tensioning assembly located below the return path of the conveyor belt; the cleaning tensioning assembly includes a fixed base fixed to the inner wall of the conveyor connecting hopper, a floating mounting plate slidably disposed on the fixed base in a vertical direction, a floating spring disposed between the floating mounting plate and the fixed base, a floating bracket disposed on the top of the floating mounting plate, an inner tensioning wheel rotatably disposed on the floating bracket and abutting against the inner surface of the conveyor belt, an outer cleaning wheel rotatably disposed on the floating bracket and abutting against the outer surface of the conveyor belt, and a transmission structure for driving the inner tensioning wheel and the outer cleaning wheel to rotate synchronously; the floating bracket has a first rotating shaft for mounting the inner tensioning wheel and a second rotating shaft for mounting the outer cleaning wheel.

[0023] By adopting the above technical solution, a cleaning and tensioning component is installed below the return path of the conveyor belt. The floating spring continuously presses the inner surface of the conveyor belt with the inner tensioning wheel to achieve automatic tensioning. At the same time, the outer cleaning wheel cleans the outer surface of the conveyor belt synchronously. This solves the problems in the background technology of conveyor belt loosening after long-term use and the impact of residue in the trough on the positioning accuracy of tubular objects. It maintains the optimal working condition of the conveyor belt without manual intervention, thereby improving the continuous stability of equipment operation.

[0024] Optionally, the transmission structure includes a transmission gear ring disposed on the outer periphery of both ends of the inner tensioning wheel, a transmission gear groove disposed on the inner side of the guide protrusion and engaging with the transmission gear ring, a drive gear coaxially fixed on the first rotating shaft, and a driven gear coaxially fixed on the second rotating shaft and meshing with the drive gear.

[0025] By adopting the above technical solution, transmission gear rings are set at both ends of the inner tension wheel to cooperate with the transmission gear grooves on the inner side of the conveyor belt. The outer cleaning wheel is driven to rotate synchronously through the driving gear and the driven gear, so that the cleaning wheel and the conveyor belt maintain a precise linear speed match. This avoids relative slippage between the cleaning wheel and the conveyor belt due to speed difference, which not only prevents damage to tubular objects or conveyor belts caused by friction, but also ensures the uniformity of cleaning effect, further improving the working reliability and service life of the cleaning tensioning component.

[0026] In summary, this application includes at least one of the following beneficial technical effects: An automatic tubular material handling and conveying device receives tubular materials from the previous process via a belt conveyor and conveys them to a material handling mechanism. The oscillating plate and material handling rollers of the material handling mechanism work together under the action of a rotary drive to continuously agitate and sort the tubular materials entering the storage hopper, thereby achieving initial tubular handling and temporary storage. Subsequently, the tubular materials undergo directional sorting and storage via a turntable conveyor mechanism, and are then transferred to the next process by a discharge conveyor mechanism. The entire process achieves automatic sorting and orderly conveying of tubular materials, thus significantly improving conveying efficiency. As the conveyor belt with grooves on its outer periphery rotates driven by the conveyor turntable, tubular materials fall from the storage hopper into the grooves and rotate with the turntable, realizing the single separation and directional conveying of the tubular materials; at the same time, the limiting bracket can prevent the tubular materials from falling out during the conveying process, further ensuring the stability of the conveying. By cooperating with the horizontal and vertical linear modules, the discharge box is moved above the storage box; then, the conveying cylinder drives the conveying plate to extend into the first and second notches, smoothly removing the tubular material from the storage box and transferring it to the discharge box; then, by cooperating with the horizontal and vertical linear modules, the tubular material in the discharge box is transferred to the next station. The whole process avoids manual intervention and improves discharge efficiency. Attached Figure Description

[0034] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0035] This application discloses an automated tubular material handling and conveying device. (Refer to...) Figure 1An automated tubular material handling and conveying device includes a belt conveyor 1 for receiving materials from the previous process, a material handling mechanism 2 located at the output end of the belt conveyor 1, a turntable conveyor mechanism 3 located at the output end of the material handling mechanism 2, and a discharge conveyor mechanism 4 located at the output end of the turntable conveyor mechanism 3. By setting up the belt conveyor 1, material handling mechanism 2, turntable conveyor mechanism 3, and discharge conveyor mechanism 4 in sequence, a fully automated conveying chain from the previous process to the packaging process is constructed, solving the problems of low efficiency of manual handling and the inability of simple conveying devices to automatically handle tubular materials in the prior art. In this embodiment, the tubular material is a beverage straw.

[0036] Reference Figure 2 The belt conveyor 1 includes a conveying support 11, a drive roller 12 and a driven roller 13 rotatably connected to both ends of the conveying support 11, a conveying belt 14 wound between the drive roller 12 and the driven roller 13, and a conveying motor 15 fixed on the conveying support 11 for driving the drive roller 12 to rotate. The conveying direction of the conveying belt 14 is towards the material handling mechanism 2.

[0037] Reference Figure 2 The material handling mechanism 2 includes a storage hopper 21 fixedly connected to the output end of the belt conveyor 1 and the input end of the turntable conveyor 3, a swing plate 22 rotatably disposed on the top of the storage hopper 21, a material handling roller 23 rotatably disposed on the top of the storage hopper 21, and a rotary drive component 24 for synchronously driving the swing plate 22 and the material handling roller 23 to rotate. The swing plate 22 extends along the width direction of the storage hopper 21, and its rotation axis is located at the top of the storage hopper 21. The material handling roller 23 is arranged parallel to the side of the swing plate 22 near the turntable conveyor 3, and its outer circumference is evenly distributed with several bristles for combing tubular materials. In this embodiment, two material handling rollers 23 are provided.

[0038] Reference Figure 3 Inside the storage hopper 21, a partition 211 is provided on the side near the swing plate 22. An arc-shaped partition 212 is also provided on the side of the partition 211 near the feeding roller 23. An clearance notch 2121 is provided on the side of the arc-shaped partition 212 facing the feeding roller 23 to accommodate part of the outer periphery of the feeding roller 23. The bottoms of the partition 211 and the arc-shaped partition 212 form a discharge gap for the tubular material. A straightening connecting cloth 213 is also provided between the bottom of the swing plate 22 and the top of the partition 211. The straightening connecting cloth 213 is a flexible cloth sheet, with one end fixed to the bottom of the swing plate 22 and the other end fixed to the top of the partition 211. This prevents the tubular material from slipping out of the gap between the swing plate 22 and the partition 211 and assists in gradually straightening the tubular material during the swinging process.

[0039] Reference Figure 2The rotary drive component 24 includes a rotary motor 241 fixed to the outside of the conveying hopper 31. The output shaft of the rotary motor 241 is fixedly connected to one side of the rotation shaft of the feeding roller 23. A first gear 242 is fixed to the other side of the rotation shaft of the feeding roller 23. The first gear 242 meshes with a second gear 243. An eccentric wheel 244 is fixed on the second gear 243. The output shaft of the eccentric wheel 244 is connected to a connecting rod 245. A connecting block 246 is hinged to the end of the connecting rod 245 away from the eccentric wheel 244. The connecting block 246 is fixedly connected to the output shaft of the swing plate 22. When the rotary motor 241 drives the feeding roller 23 to rotate, the feeding roller 23 drives the first gear 242 to rotate. The first gear 242 drives the second gear 243 to rotate. The second gear 243 drives the eccentric wheel 244 to rotate. The eccentric wheel 244 drives the connecting block 246 to swing back and forth through the connecting rod 245, thereby driving the swing plate 22 to swing back and forth.

[0040] Reference Figure 4 The turntable conveyor mechanism 3 includes a conveying hopper 31 fixedly connected to the storage hopper 21, a conveying turntable 32 disposed within the conveying hopper 31, a conveyor belt 33 detachably disposed on the outer periphery of the conveying turntable 32, a limiting bracket 34 disposed on the conveying hopper 31 for limiting tubular objects, and a drive motor 35 fixed to the outside of the conveying hopper 31 for driving the conveying turntable 32 to rotate. The outer periphery of the conveyor belt 33 is continuously and uniformly provided with several circumferential grooves 331. The size of the grooves 331 matches the outer diameter of the tubular object, used to accommodate a single tubular object. The bottom of the conveying hopper 31 has an inlet communicating with the bottom opening of the storage hopper 21. After the tubular object falls from the storage hopper 21 into the conveying hopper 31, it falls into the grooves 331 of the conveyor belt 33 under gravity, and rotates with the conveying turntable 32 to the top outlet of the conveying hopper 31.

[0041] Reference Figure 4 The conveyor belt 33 is detachably fitted onto the outer periphery of the conveyor turntable 32. Multiple strong magnetic blocks 321 are evenly embedded on the outer periphery of the conveyor turntable 32. Corresponding positions on the inner side of the conveyor belt 33 are provided with magnetically attracted metal pieces 332 that magnetically engage with the strong magnetic blocks 321. Two guide protrusions 333 are also provided along the length of the inner side of the conveyor belt 33. Guide grooves 322 are provided on the outer periphery of the conveyor turntable 32 for sliding engagement with the guide protrusions 333. Both ends of the conveyor belt 33 are equipped with mating latches. By engaging the mating latches, the conveyor belt 33 can be connected end-to-end to form a loop. Through the attraction between the strong magnetic blocks 321 and the magnetically attracted metal pieces 332, and the engagement of the guide protrusions 333 and the guide grooves 322, the conveyor belt 33 can be quickly installed and precisely positioned on the conveyor turntable 32. In this embodiment, the mating latches are common metal letter snap fasteners in the prior art.

[0042] Reference Figure 4The limiting bracket 34 is set on the conveyor connecting hopper 31 and is located on the outside of the conveyor belt 33. Its shape is adapted to the outer periphery of the conveyor belt 33 and is used to prevent the tubular object from coming out of the tube groove 331 during the conveying process.

[0043] Reference Figure 4 and Figure 6 In addition, a cleaning tensioning assembly 312 is provided inside the conveyor connecting hopper 31, located below the return path of the conveyor belt 33. The cleaning tensioning assembly 312 includes a fixed base 3121 fixed to the inner wall of the conveyor connecting hopper 31, a floating mounting plate 3122 slidably mounted on the fixed base 3121 in the vertical direction, a floating spring 3123 between the floating mounting plate 3122 and the fixed base 3121, a floating bracket 3124 on the top of the floating mounting plate 3122, an inner tensioning wheel 3125 rotatably mounted on the floating bracket 3124 and abutting against the inner surface of the conveyor belt 33, an outer cleaning wheel 3126 rotatably mounted on the floating bracket 3124 and abutting against the outer surface of the conveyor belt 33, and a transmission structure 3127 for driving the inner tensioning wheel 3125 and the outer cleaning wheel 3126 to rotate synchronously. The floating support 3124 has a first pivot 31241 for mounting the inner tension wheel 3125 and a second pivot 31242 for mounting the outer cleaning wheel 3126.

[0044] Reference Figure 4 and Figure 6 The transmission structure 3127 includes a transmission gear ring 31251 located on the outer periphery of both ends of the inner tensioning wheel 3125, a transmission gear groove 3331 located on the inner side of the guide protrusion 333 and engaging with the transmission gear ring 31251, a drive gear 312411 coaxially fixed on the first rotating shaft 31241, and a driven gear 312421 coaxially fixed on the second rotating shaft 31242 and meshing with the drive gear 312411.

[0045] Reference Figure 4 and Figure 6 Specifically, under the elastic force of the floating spring 3123, the inner tensioning wheel 3125 always presses against the inner surface of the conveyor belt 33, applying tension to the conveyor belt 33. When the conveyor belt 33 is running, the inner transmission tooth groove 3331 meshes with the transmission tooth rings 31251 at both ends of the inner tensioning wheel 3125, driving the inner tensioning wheel 3125 and the first rotating shaft 31241 to rotate. In turn, the outer cleaning wheel 3126 is driven to rotate synchronously through the meshing of the driving gear 312411 and the driven gear 312421. The linear speed of the outer cleaning wheel 3126 is consistent with the linear speed of the conveyor belt 33, thereby cleaning the groove 331 on the conveyor belt 33 while avoiding wear on the conveyor belt 33 due to speed difference.

[0046] Reference Figure 3 and 6The top of the conveyor hopper 31 is also provided with a storage box 311 for receiving tubular objects from the conveyor belt 33. The bottom of the storage box 311 has a receiving interface 3111 for the tubular objects to enter and a first notch 3112 for the discharge conveying mechanism 4 to extend into. The side wall of the storage box 311 has a second notch 3113 that communicates with the first notch 3112. When the conveyor belt 33 drives the tubular object to rotate to the top, the tubular object comes out of the tube groove 331 and falls into the storage box 311 for temporary storage through the receiving interface 3111.

[0047] Reference Figure 1 and Figure 3 The discharge conveying mechanism 4 includes a discharge bracket 41 located near the output end of the turntable conveying mechanism 3, a horizontal linear module 42 mounted on the discharge bracket 41, a horizontal mounting plate 43 located at the output end of the horizontal linear module 42, a vertical linear module 44 mounted vertically on the horizontal mounting plate 43, and a discharge box 46 located at the output end of the vertical linear module 44. A conveying cylinder 461 is also vertically mounted on the outer wall of the discharge box 46, and the output end of the conveying cylinder 461 is provided with a conveying plate 462 that cooperates with the first notch 3112 and the second notch 3113. In this embodiment, both the horizontal linear module 42 and the vertical linear module 44 can be synchronous belt modules.

[0048] Reference Figure 2 and 3 A first electrostatic precipitator 16 is provided on the top of the belt conveyor 1 near the material handling mechanism 2. The first electrostatic precipitator 16 is used to eliminate static electricity generated by the tubular material during belt conveying. A second electrostatic precipitator 313 is provided on the top of the conveyor connecting hopper 31 and the limiting bracket 34. The second electrostatic precipitator 313 is used to eliminate static electricity generated by the tubular material during turntable conveying.

[0049] The working principle of an automatic tubular material handling and conveying device according to an embodiment of this application is as follows: First, the tubular material that has been cut in the previous process falls onto the conveyor belt 14 of the belt conveyor 1. The conveyor motor drives the conveyor belt 14 to transport the tubular material towards the material handling mechanism 2. After the tubular material is destaticated by the first electrostatic device 16, it falls into the storage hopper 21. Subsequently, the rotary motor 241 drives the material-sorting roller 23 to rotate continuously. At the same time, through the transmission of the first gear 242, the second gear 243, the eccentric wheel 244, the connecting rod 245, and the connecting block 246, the swing plate 22 is driven to swing back and forth. The swinging action of the swing plate 22 and the rotation action of the material-sorting roller 23 work together: the swing plate 22 continuously moves and sorts the tubular materials in the storage hopper 21 to prevent the tubular materials from accumulating or bridging in the storage hopper 21. At the same time, the material-sorting roller 23 uses the bristles on its outer periphery to sort the tubular materials entering the tube groove 331 of the conveyor belt 33, so that the tubular materials can smoothly enter the tube groove 331. Simultaneously, the straightening connecting cloth 213 relaxes and expands with the swinging of the swing plate 22 to help the tubular materials gradually straighten. Subsequently, the conveyor turntable 32 rotates under the drive of the drive motor 35, causing the conveyor belt 33 to rotate; the tubular material falling into the conveyor connecting hopper 31 enters the tube groove 331 of the conveyor belt 33 under the action of gravity, and is conveyed upward with the conveyor belt 33; at the same time, the limiting bracket 34 prevents the tubular material from falling out of the tube groove 331 during the conveying process, and the second electrostatic device 313 further eliminates the static electricity generated by the tubular material during the conveying process; when the conveyor belt 33 rotates to the top, the tubular material falls out of the tube groove 331 and falls into the storage box 311 for temporary storage through the receiving interface 3111; Next, during the operation of the conveyor belt 33, the cleaning tensioning assembly 312 works automatically: the floating spring 3123 keeps the inner tensioning wheel 3125 in close contact with the inner surface of the conveyor belt 33, providing continuous tension; at the same time, the transmission tooth groove 3331 on the inner side of the conveyor belt 33 meshes with the transmission tooth ring 31251, driving the inner tensioning wheel 3125 and the first rotating shaft 31241 to rotate, and then driving the outer cleaning wheel 3126 to rotate synchronously through the meshing of the driving gear 312411 and the driven gear 312421, thereby removing impurities in the trough 331; Finally, when the discharge conveying mechanism 4 is working, the horizontal linear module 42 and the vertical linear module 44 cooperate to first move the discharge box 46 above the storage box 311. Then, the conveying cylinder 461 drives the conveying plate 462 to extend into the first notch 3112 and the second notch 3113 to smoothly remove the tubular material in the storage box 311 and transfer it to the discharge box 46. Then, through the cooperation of the horizontal linear module 42 and the vertical linear module 44, the tubular material in the discharge box 46 is transferred to the packaging equipment of the next process.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
