Description

Technical Field

[0001] This application relates to the field of small guide tube manufacturing technology, and in particular to an automatic packaging equipment and process for small guide tubes used in tunnels. Background Technology

[0002] Small guide pipes are widely used in underground engineering projects such as tunnels and mines. In tunnel construction, small guide pipes are often used for pre-support. Due to the complex geological conditions of the surrounding rock in tunnels, safety issues such as collapses may occur during excavation. Small guide pipes can be pre-driven into the surrounding rock to reinforce and stabilize it, creating safer conditions for subsequent excavation and support work.

[0003] Small guide tubes are hollow steel pipes with a conical shape at one end and multiple perforations on the outer wall. After the small guide tubes are produced, they need to be stacked and packaged, so an automatic packaging equipment is required. Summary of the Invention

[0004] To facilitate the packaging of small guide pipes, this application provides an automatic packaging device and process for small guide pipes used in tunnels.

[0005] In a first aspect, this application provides an automatic packaging device for small guide pipes used in tunnels, which adopts the following technical solution: An automatic packaging device for small guide pipes used in tunnels includes a feeding mechanism for carrying and controlling the transport of the small guide pipes. The transfer mechanism includes a loading rack located at the unloading end of the unloading mechanism and a conveying assembly located on the loading rack, the conveying assembly being used to convey small guide tubes falling into the loading rack; A packaging mechanism, located at the output end of the transfer mechanism, is used to package the small conduits removed from the loading rack.

[0006] By adopting the above technical solution, this application achieves full automation of the entire process from receiving and temporarily storing small guide tubes to conveying and packaging them by setting up a feeding mechanism, a transfer mechanism, and a packaging mechanism. The feeding mechanism releases the small guide tubes in an orderly manner, the transfer mechanism receives and conveys the entire batch of small guide tubes, and finally the packaging mechanism completes the packaging operation. The three work together to form a continuous automated processing flow, which helps to improve production efficiency.

[0007] Optionally, the unloading mechanism includes an unloading frame, a first power telescopic member, and a blocking member. The top wall of the unloading frame is inclined, and the lower end of the top wall of the unloading frame faces the loading frame. The first power telescopic member is connected to the unloading frame, and the blocking member is rotatably connected to the unloading frame. One end of the blocking member is used to abut against a small guide tube placed on the top wall of the unloading frame. The blocking member has a sliding groove, and the movable end of the first power telescopic member is slidably connected to the sliding groove so that the blocking member can be driven to rotate when the first power telescopic member is activated.

[0008] By adopting the above technical solution, the inclined top wall of the unloading rack uses gravity to automatically slide the small guide tube into the loading rack, simplifying the conveying structure; the first power telescopic component drives the blocking component with a sliding groove to rotate, realizing the rotation control of the blocking component. When one end of the blocking component deflects upward, it can block the small guide tube, so as to temporarily store the small guide tubes produced on the production line; when the end of the blocking component deflects downward, it releases the obstruction of the small guide tube, and the small guide tubes are unloaded in batches using gravity; the structure is stable and the control is precise, which helps to realize the automated unloading of small guide tubes.

[0009] Optionally, the loading rack includes a base and baffles on both sides of the base. The baffles on both sides of the base are inclined at the ends away from the base towards the opposite side. Rotating rollers are rotatably connected to the sides of the baffles on both sides of the base that are close to each other. The rotating rollers are used to abut against the small guide tubes placed in the loading rack.

[0010] By adopting the above technical solution, the baffles on both sides of the loading rack are inclined upwards and outwards, forming an open guide inlet. This structure increases the effective opening area for the small guide tube to fall into the loading rack, playing a guiding and buffering role, allowing the small guide tube to slide smoothly into the loading rack and avoiding problems such as jamming or scattering caused by deviation in the falling position. A rotating roller is added to the inside of the baffle. When the small guide tube slides axially in the loading rack due to sorting or conveying, the side wall of the small guide tube contacts the rotating roller. The rotating roller converts the sliding friction between the two into rolling friction, reducing the frictional resistance encountered by the small guide tube during the conveying process, making the conveying smoother, and also reducing wear on the surface of the small guide tube.

[0011] Optionally, the conveying assembly includes a conveying roller and a driving component. The conveying roller is rotatably connected to the loading rack. The conveying roller is used to abut against a small guide tube placed at the bottom of the loading rack. Multiple conveying rollers are provided and arranged at intervals along the length of the loading rack. The driving component is used to drive the conveying roller to rotate.

[0012] By adopting the above technical solution, multiple conveying rollers driven by drive components are set at the bottom of the loading rack, which can directly drive the bottom of the entire stack of small guide tubes in the loading rack; by driving the bottom layer of small guide tubes, the upper layer of small guide tubes are driven forward smoothly, realizing the synchronous conveying of the entire batch of materials. The transmission is smooth, which makes it easy to quickly and as a whole convey the stacked small guide tubes to the packaging mechanism for continuous packaging operations.

[0013] Optionally, both sides of the loading rack are provided with a material straightening mechanism. The material straightening mechanism includes a second power telescopic member and a material straightening plate located at the movable end of the second power telescopic member. The side of the material straightening plate in the two sets of material straightening mechanisms that is close to each other is provided with an inclined surface. The side of the inclined surface on the two sets of material straightening plates that is away from the base is inclined towards the side that is close to each other. The inclined surface is used to abut against the small guide tube placed in the loading rack.

[0014] By adopting the above technical solution, the material-forming mechanisms on both sides can work together during the batch feeding process. After each batch of small guide tubes falls from the feeding rack, the second power telescopic component drives the material-forming plate to move inward, and its inclined surface can push and organize the relatively loose small guide tubes in the upper layer towards the center. Through multiple, layer-by-layer pushing and organizing, the small guide tubes can be guided to stack into a more compact hexagonal close-packed structure. This structure is more stable, facilitates subsequent circumferential bundling, and is less prone to loosening after packaging.

[0015] Optionally, the outer side of the loading rack is provided with a pushing mechanism, which includes a pushing component and a blocking component. The pushing component includes a push plate and a third power telescopic member. The third power telescopic member is disposed at the end of the loading rack away from the packaging mechanism. The push plate is connected to the movable end of the third power telescopic member. The third power telescopic member is used to drive the push plate to push the small guide tube placed in the loading rack to slide axially. The blocking component includes a baffle plate and a fourth power telescopic member. The fourth power telescopic member is disposed at the end of the loading rack near the packaging mechanism. The baffle plate is connected to the movable end of the fourth power telescopic member. The fourth power telescopic member is used to drive the baffle plate to slide radially along the small guide tube placed in the loading rack. The baffle plate is used to abut against the first end of the small guide tube placed in the loading rack.

[0016] By adopting the above technical solution, the fourth power telescopic component drives the baffle plate to move onto the conveying path of the small guide tubes in the loading rack, blocking the ends of the small guide tubes; the third power telescopic component then drives the push plate to push the small guide tubes until the front ends of all the small guide tubes are pressed against the baffle plate, thereby ensuring that the two ends of the entire batch of small guide tubes are flush and improving the sorting quality before packaging.

[0017] Furthermore, the mechanism can achieve step-by-step conveying. First, the front end of the small guide tube stack is pushed out to the packaging mechanism for initial bundling to fix the front end of the small guide tube. Then, the conveying component conveys the small guide tube as a whole, thereby avoiding the difference in conveying speed and relative slippage caused by the different contact conditions between the upper and lower layers of small guide tubes and the conveying roller. This ensures that the end faces of the entire bundle of small guide tubes are flush during subsequent conveying and packaging processes, thus guaranteeing the subsequent packaging effect.

[0018] Optionally, an abutment plate is slidably connected to the push plate, the abutment plate being used to abut against the second end of the small guide tube placed in the loading rack, and an elastic element is connected between the push plate and the abutment plate.

[0019] By adopting the above technical solution, when the abutment plate pushes the small guide tube until its other end touches the baffle plate, if the third power telescopic component still has a small stroke, this stroke can be absorbed by the compression of the elastic component. This can apply a continuous and gentle alignment pressure to the small guide tube, ensuring a tight fit between the end faces, and can effectively avoid damage to the power telescopic component or the small guide tube caused by rigid collisions, thereby increasing the system's fault tolerance and operational safety.

[0020] Optionally, the base is slidably connected to a support rod, and there are two support rods arranged in parallel and spaced apart on both sides of the base. Each support rod is connected to a baffle on one side of the base. The base is also provided with a drive assembly for driving the two support rods to slide in opposite directions.

[0021] By adopting the above technical solution, during the process of small guide tubes falling and stacking, the drive component can control the baffle and the rotating roller on the baffle to slide back and forth in small amplitudes, so that the distance between the rotating rollers on both sides continuously changes. This change can apply a dynamic disturbance and compression to the stacked small guide tubes, prompting them to better fill the gaps by misalignment, avoiding the local material from being suspended or arched, making the stacking of small guide tubes more compact and uniform, improving the quality of stacking, and thus making it less likely to loosen after subsequent packaging and bundling, thereby enhancing the packaging effect.

[0022] Optionally, the drive assembly includes a rotary power component and a bidirectional lead screw. The rotary power component is connected to the base, and the bidirectional lead screw is coaxially connected to the movable end of the rotary power component. The two ends of the bidirectional lead screw have opposite thread directions. Each support rod is provided with a connecting block. The connecting block on the first support rod is threadedly connected to the first end of the bidirectional lead screw, and the connecting block on the second support rod is threadedly connected to the second end of the bidirectional lead screw.

[0023] By adopting the above technical solution, the bidirectional screw can drive the two connecting blocks to slide in opposite directions when rotating, ensuring the consistency and coordination of the actions of the baffles on both sides. At the same time, the bidirectional screw transmission structure has a self-locking characteristic, that is, after the driving force is removed, the connecting blocks cannot drive the bidirectional screw to rotate in the opposite direction, thereby precisely locking the baffle in any position, so that the shape of the stacked small guide tube bundles is consistent, providing a reliable guarantee for achieving standardized packaging.

[0024] Secondly, this application provides a process, which adopts the following technical solution: A process, employing the aforementioned automated packaging equipment for small tunnel guide pipes, includes the following steps: Step S1, Unloading and Stacking: Control the unloading mechanism to make the small guide tubes fall into the loading rack in batches; during the unloading process, intermittently control the second power telescopic component to drive the two sides of the material plate to move towards each other, and push the small guide tubes with the inclined surface to make the small guide tubes stacked tightly in a hexagonal shape until the loading rack contains a preset number of small guide tubes. Step S2, Blocking and Positioning: Stop the feeding action of the feeding mechanism, control the action of the fourth power telescopic component, and drive the baffle plate to move onto the conveying path of the small guide tube; Step S3, end face flush: Control the third power telescopic component to drive the push plate to drive the abutment plate to push the small guide tube in the loading rack to slide axially until the first end of the small guide tube is abutted against the baffle plate. Step S4, Reset and Avoidance: Control the third power telescopic component to drive the push plate to move in the opposite direction to reset, and the fourth power telescopic component to drive the baffle plate to move out of the small guide pipe conveying path; Step S5, First end shaping and packaging: Control the third power telescopic component to move again, drive the push plate to move the small guide tube material pile after the end faces are aligned, so that the first end of the small guide tube extends into the packaging mechanism, and control the packaging mechanism to perform the first binding and fixing of the front end of the small guide tube. Step S6, Overall Conveying and Continuous Packaging: Control the transfer mechanism to start, and convey the bundled small guide tube material pile at the front end to the packaging mechanism. The packaging mechanism performs multiple interval packaging along the length of the small guide tube.

[0025] By adopting the above technical solutions and cooperating with each mechanism, the entire process of small guide tubes from material feeding to packaging is automated, which helps to improve production efficiency. During the packaging process, the end faces of the small guide tube stack can be kept flush by the pushing mechanism, and the small guide tubes can be tightly stacked in a hexagonal shape by the material straightening mechanism, thereby improving the stability of the small guide tube stack after packaging.

[0026] In summary, this application includes the following beneficial technical effects: 1. The modular combination and collaborative operation of the feeding mechanism, transfer mechanism and packaging mechanism realize the full automation of the small guide tube from the end of the production line to the completion of packaging, reduce manual intervention and improve production efficiency and continuity.

[0027] 2. Moving the two material plates closer to each other will push the small guide tubes in the upper layer of the loading rack inward, and push and organize the relatively loose small guide tubes in the upper layer of the loading rack towards the center. Through multiple layers of pushing and organizing, the small guide tubes can be guided to stack into a more compact hexagonal close-packed structure. This structure is more stable, facilitates subsequent circumferential binding, and is not easy to loosen after packaging.

[0028] 3. During the process of the small guide tubes falling and stacking, the drive component can control the baffle and the rotating roller on the baffle to slide back and forth in a small amplitude. This sliding can apply a dynamic disturbance and compression to the stacked small guide tubes, prompting them to better fill the gaps by misalignment, avoiding local material from being suspended or arched, making the stacking of small guide tubes more compact and uniform, improving the quality of stacking, and thus making it less likely to loosen after subsequent packaging and bundling, thereby enhancing the packaging effect.

[0029] 4. The pusher mechanism and the conveying component work together to achieve step-by-step conveying. First, the front end of the small guide tube stack is pushed out to the packaging mechanism for initial bundling. After the front end of the small guide tube is fixed, the conveying component conveys the small guide tube as a whole. This avoids the difference in conveying speed and relative slippage caused by the different contact conditions between the upper and lower layers of small guide tubes and the conveying rollers. It ensures that the end faces of the whole bundle of small guide tubes are flush during the subsequent conveying and packaging process, so as to ensure the subsequent packaging effect.

[0032] The following combination Figures 1-7 This application will be described in further detail.

[0033] Example 1: This application discloses an automatic packaging device for small guide pipes used in tunnels. This device mainly serves as a downstream supporting equipment in a small guide pipe production line, automating the packaging process. (Refer to...) Figure 1 and Figure 2 The automatic packaging equipment for small guide pipes used in tunnels includes a feeding mechanism 1, a transfer mechanism 2, and a packaging mechanism 3. These three mechanisms are arranged in sequence along the conveying direction of the small guide pipe 10. The three mechanisms are described in turn below.

[0034] Reference Figure 2 and Figure 3 The unloading mechanism 1 is used to receive the small guide tubes 10 output from the production line. The unloading mechanism 1 includes an unloading frame 11, a first power telescopic member 12, and a blocking member 13. The top wall of the unloading frame 11 is an inclined plane, with the lower end of the top wall of the unloading frame 11 facing the subsequent transfer mechanism 2. The small guide tubes 10 are placed on the inclined top wall of the unloading frame 11 and can slide downwards by gravity, thereby realizing the transfer and conveying process of the small guide tubes 10.

[0035] Reference Figure 3 and Figure 4The first power telescopic component 12 is a cylinder, which is fixedly installed on the unloading rack 11. The first power telescopic component 12 is arranged along the inclined direction of the top wall of the unloading rack 11, and the piston rod of the first power telescopic component 12 faces the lower side of the top wall of the unloading rack 11. The blocking component 13 is rotatably connected to the top of the unloading rack 11, and the rotation axis of the blocking component 13 is parallel to the length direction of the unloading rack 11. The blocking component 13 is arranged in a V-shape, and the middle part of the blocking component 13 is rotatably connected to the unloading rack 11. One end of the blocking component 13 can be raised to block the small guide tube 10, or lowered to release the small guide tube 10; the other end of the blocking component 13 is provided with a sliding groove 131, and the piston rod end of the first power telescopic component 12 is fixedly connected to a connecting post 121, which slides through the sliding groove 131. Therefore, the first power telescopic component 12 can drive the blocking component 13 to rotate, thereby controlling the state of the multiple small guide tubes 10 placed on the top wall of the unloading rack 11.

[0036] Reference Figure 4 Under normal conditions, the top of the blocking member 13 protrudes from the top surface of the unloading rack 11, and the top of the blocking member 13 is perpendicular to the top wall of the unloading rack 11. The blocking member 13 can block multiple small guide tubes 10 placed on the top wall of the unloading rack 11. When the piston rod of the first power telescopic member 12 retracts, its movable end drives the top of the blocking member 13 to rotate downward through the cooperation of the connecting column 121 and the slide groove 131, until the entire blocking member 13 is located in the area below the top wall of the unloading rack 11. At this time, due to the absence of the blocking member 13, the small guide tubes 10 on the top wall of the unloading rack 11 can roll freely downward under the action of gravity, thus falling into the transfer mechanism 2. Therefore, a batch of small guide tubes 10 can be unloaded at a set time. This design ensures that the processed small guide tubes 10 can enter the next stage according to the preset rhythm.

[0037] Reference Figure 3 The first power telescopic component 12 is provided in multiples, and the multiple first power telescopic components 12 are evenly spaced along the length direction of the unloading frame 11. The number of blocking components 13 is the same as the number of first power telescopic components 12. Each blocking component 13 is connected to the corresponding first power telescopic component 12, so that the small guide tube 10 can be blocked by multiple blocking components 13 to ensure the stability of the blocking process of the small guide tube 10.

[0038] Reference Figure 5After the unloading mechanism 1 releases the small guide tube 10, the small guide tube 10 falls into the transfer mechanism 2. The transfer mechanism 2 includes a loading rack 21 and a conveying assembly 22 disposed on the loading rack 21. The loading rack 21 includes a base 211 and baffles 212 fixedly installed on both sides of the base 211; the base 211 is arranged along the length direction of the unloading rack 11, and there are two sets of baffles 212, each set including multiple baffles evenly spaced along the length direction of the base 211; the baffles 212 on both sides of the base 211 are inclined, and the tops of the baffles 212 on both sides are inclined toward the side that is far away from each other, thus forming an opening to facilitate the smooth falling of the small guide tube 10. In order to reduce the friction of the small guide tube 10 during subsequent movement, a rotating roller 2121 is rotatably connected to the inner side of each baffle 212, and the axis of the rotating roller 2121 is parallel to the length direction of the corresponding baffle 212; the small guide tube 10 can rest on the rotating roller 2121, changing sliding friction into rolling friction.

[0039] The conveying assembly 22 includes a conveying roller 221 and a driving component 222. The conveying roller 221 is rotatably connected to the base 211, and the axis of rotation of the conveying roller 221 is parallel to the width direction of the base 211. Multiple conveying rollers 221 are provided, and the multiple conveying rollers 221 are evenly spaced along the length direction of the base 211. The top of the conveying roller 221 is slightly higher than the bottom surface of the base 211, so that the top of the conveying roller 221 can contact the bottommost small guide tube 10 placed in the loading rack 21. The driving component 222 is used to drive the conveying roller 221 to rotate, so that the conveying roller 221 can convey the small guide tube 10 placed in the loading rack 21 as a whole, and the conveying direction is the axial direction of the small guide tube 10.

[0040] The drive component 222 includes a motor 2221, sprockets 2222, and chains 2223. The motor 2221 is fixedly mounted on the base 211, and the output shaft of the motor 2221 is arranged along the width direction of the base 211. Multiple sprockets 2222 are provided, and the number of sprockets 2222 is the same as the number of conveying rollers 221 and corresponds one-to-one. Each sprocket 2222 is coaxially fixedly connected to the end of the corresponding conveying roller 221. Multiple chains 2223 are provided, and the chains 2223 are wound between two adjacent sprockets 2222. One of the sprockets 2222 is coaxially connected to the output shaft of the motor 2221. Therefore, after the motor 2221 is started, it can drive the sprockets 2222 and chains 2223 to rotate, thereby making multiple conveying rollers 221 rotate synchronously to achieve the overall conveying of the small guide tube 10.

[0041] Reference Figure 5To ensure the small guide tubes 10 in the loading rack 21 are stacked more neatly, a material balancing mechanism 4 is provided on both sides of the loading rack 21. Each material balancing mechanism 4 includes a second power telescopic member 41 and a material balancing plate 42. The second power telescopic member 41 is a servo electric cylinder, and the extension or retraction distance of the movable end of the servo electric cylinder can be precisely adjusted. The movable end of the second power telescopic member 41 is fixedly connected to a mounting plate 43, which is arranged along the length of the base 211. The material balancing plate 42 is fixedly connected to the mounting plate 43, and multiple material balancing plates 42 are provided, which are evenly spaced along the length of the mounting plate 43. The sides of the material balancing plates 42 in the material balancing mechanisms 4 on both sides that are close to each other are provided with inclined surfaces 421 for abutting against the small guide tubes 10, and the tops of the inclined surfaces 421 on both sides of the material balancing plates 42 are inclined towards the side that is close to each other, that is, the inclination direction of the inclined surfaces 421 on the material balancing plates 42 is opposite to the inclination direction of the baffle 212.

[0042] During the process of the small guide tubes 10 falling from the unloading rack 11 into the loading rack 21, at the beginning of the unloading, the inclined surfaces 421 on both sides of the material plates 42 are located outside the baffles 212; therefore, the falling small guide tubes 10 can directly fall into the area between the two baffles 212, initially stacking in an inverted trapezoidal arrangement at the bottom of the loading rack 21. After the small guide tubes 10 on the loading rack 21 have stacked to a certain height (such as half the height of the baffles 212), each time a batch of small guide tubes 10 falls, the two second power telescopic components 41 can drive the material plates 42 on both sides to move a certain distance towards each other, and the inclined surfaces 421 on the material plates 42 push the upper layer of small guide tubes 10 towards the center. Through this layer-by-layer arrangement, the entire pile of small guide tubes 10 eventually forms a tight hexagonal stack, thus preparing for subsequent packaging.

[0043] To ensure that the two ends of the small guide tube 10 are flush before being conveyed to the packaging mechanism 3, a pushing mechanism 5 is also provided on the outer side of the loading rack 21. The pushing mechanism 5 includes a pushing component 51 and a blocking component 52. The blocking component 52 is located at one end of the loading rack 21 near the packaging mechanism 3. The blocking component 52 includes a fourth power telescopic member 522 and a baffle plate 521. The fourth power telescopic member 522 is a servo electric cylinder, and the movable end of the fourth power telescopic member 522 faces vertically downward. The baffle plate 521 is fixedly installed on the movable end of the fourth power telescopic member 522 and is used to abut against the first end of the small guide tube 10 to limit the axial sliding of the small guide tube 10.

[0044] The pushing component 51 is located at the end of the loading rack 21 away from the packaging mechanism 3. The pushing component 51 includes a third power telescopic member 512 and a push plate 511. The third power telescopic member 512 is a servo electric cylinder, which is arranged along the length of the base 211, and the movable end of the third power telescopic member 512 faces away from the blocking component 52. The push plate 511 is fixedly connected to the movable end of the third power telescopic member 512, and the push plate 511 is used to abut against the second end of the small guide tube 10.

[0045] During operation, after the unloading process of the small guide tubes 10 on the feeder 11 is completed, the loading rack 21 contains the required number of small guide tubes 10. At this time, the fourth power telescopic component 522 first drives the baffle plate 521 to descend onto the conveying path of the small guide tubes 10. Then, the third power telescopic component 512 drives the push plate 511 forward, and the push plate 511 pushes the entire stack of small guide tubes 10 axially until the ends of all the small guide tubes 10 are pressed against the baffle plate 521. This process ensures that the end faces of all the small guide tubes 10 are flush, guaranteeing the neatness of the stack. Furthermore, the front end of the small guide tubes 10 can be pushed out first by the push plate 511, allowing the packaging mechanism 3 to tie it once and fix the front end; then the conveying roller 221 is started for overall conveying, thereby effectively preventing the small guide tubes 10, which have already undergone end-flushing treatment, from scattering during the conveying process.

[0046] Furthermore, to prevent rigid collision between the push plate 511 and the end of the small guide tube 10, an abutment plate 6 is provided on the side of the push plate 511 near the blocking assembly 52. ​​A guide rod 61 is fixedly connected to the abutment plate 6. A through hole is provided on the push plate 511, and the guide rod 61 slides horizontally through the through hole, so that the abutment plate 6 and the push plate 511 are slidably connected. An elastic element 7 is connected between the abutment plate 6 and the push plate 511. The elastic element 7 is a spring, which is sleeved on the outside of the guide rod 61 and fixedly connected between the abutment plate 6 and the push plate 511. Under normal conditions, the elastic element 7 is at its original length. When the end face of the small guide tube 10 has pressed against the baffle plate 521, the push plate 511 can still continue to advance a small distance. This displacement is absorbed by the elastic element 7. This ensures that the small guide tube 10 is continuously pressed and avoids impact on the transmission system, improving the smoothness and reliability of the equipment operation.

[0047] Reference Figure 1 The packaging mechanism 3 is located on the side of the blocking component 52 away from the loading rack 21. The packaging mechanism 3 is a belt packaging machine. Therefore, when the small guide tube 10 passes through the packaging mechanism 3, the packaging mechanism 3 can wrap and tie the packaging strap on the outermost side of the neatly stacked small guide tube 10. Then, after the small guide tube 10 is conveyed forward a certain distance, the packaging mechanism 3 will tie the packaging strap on the small guide tube 10 again. Repeat the above process, and wrap four to five packaging straps at intervals on the outer side of the small guide tube 10.

[0048] The implementation principle of Example 1 is as follows: The small guide tubes 10 coming off the production line first fall onto the top wall of the unloading rack 11 for temporary storage, blocked by the blocking member 13. When unloading is required, the movable end of the first power telescopic member 12 retracts, the blocking member 13 rotates to release, and the small guide tubes 10 slide into the loading rack 21 one by one. In the initial stage of unloading, under the restriction of the baffle 212, the small guide tubes 10 sliding into the loading rack 21 are stacked in an inverted trapezoidal shape. When the height of the small guide tubes 10 in the loading rack 21 reaches half the height of the baffle 212, each time a batch of small guide tubes 10 falls, the second power telescopic members 41 on both sides drive the material plates 42 on both sides to push and squeeze inward, so that the small guide tubes 10 gradually form a hexagonal stack.

[0049] When the required number of small guide tubes 10 are stacked in the loading rack 21, the feeding of the small guide tubes 10 is stopped. Then, the fourth power telescopic member 522 drives the baffle plate 521 to move downward, moving the baffle plate 521 into the moving path of the small guide tubes 10. Then, the third power telescopic member 512 drives the push plate 511 to move horizontally. The push plate 511 and the abutment plate 6 move together, pushing the small guide tubes 10 to move as a whole until the ends of the small guide tubes 10 abut against the baffle plate 521, thereby keeping the ends of all the small guide tubes 10 flush. Next, the push plate 511 slides in the reverse direction and resets, and the baffle plate 521 moves upward and resets. Then, the small guide tubes 10 are conveyed into the packaging mechanism 3.

[0050] During transport, the pusher plate 511 pushes the small guide tube 10 forward as a whole, causing one end of the small guide tube 10 to pass through the packaging mechanism 3, and then stops pushing the small guide tube 10; the packaging mechanism 3 then ties a packing strap to the end of the small guide tube 10. Then the pusher plate 511 moves in the reverse direction to reset, and the drive component 222 drives the conveyor roller 221 to rotate, transporting the small guide tube 10 with the tied end forward as a whole. Because the end of the small guide tube 10 has been initially tied, the upper and lower layers of the small guide tube 10 are less likely to slide relative to each other during transport, thus ensuring the overall transport effect of the small guide tube 10. Subsequent transport of the small guide tube 10 can be done intermittently by repeatedly tying packing straps at different positions on the small guide tube 10.

[0051] This embodiment also discloses a process that utilizes the aforementioned automated packaging equipment for small tunnel guide pipes. The process includes the following steps: Step S1, Unloading and Stacking: Control the unloading mechanism 1 to make the small guide tubes 10 fall into the loading rack 21 in batches; during the unloading process, intermittently control the second power telescopic component 41 to drive the material plates 42 on both sides to move towards each other, and push the small guide tubes 10 through the inclined surface 421 to make the small guide tubes 10 stacked tightly in a hexagonal shape until the loading rack 21 contains a preset number of small guide tubes 10.

[0052] Step S2, Blocking Positioning: Stop the feeding action of the feeding mechanism 1, control the action of the fourth power telescopic component 522, and drive the baffle plate 521 to move onto the conveying path of the small guide tube 10.

[0053] Step S3, end face flush: Control the third power telescopic component 512 to drive the push plate 511 to drive the abutment plate 6 to push the small guide tube 10 in the loading rack 21 to slide axially until the first end of the small guide tube 10 abuts against the baffle plate 521.

[0054] Step S4, Reset and Avoidance: Control the third power telescopic component 512 to drive the push plate 511 to move in the opposite direction and reset, and the fourth power telescopic component 522 to drive the baffle plate 521 to move out of the conveying path of the small guide tube 10.

[0055] Step S5, First end shaping and packaging: Control the third power telescopic component 512 to move again, drive the push plate 511 to push the small guide tube 10 material pile after the end face is aligned, so that the first end of the small guide tube 10 extends into the packaging mechanism 3, and control the packaging mechanism 3 to perform the first binding and fixing of the front end of the small guide tube 10.

[0056] Step S6, Overall Conveying and Continuous Packaging: Control the transfer mechanism 2 to start, and convey the bundled small guide tube 10 material pile to the packaging mechanism 3. The packaging mechanism 3 performs multiple interval packaging along the length of the small guide tube 10.

[0057] Example 2: Refer to Figure 6 and Figure 7 The difference between this embodiment and Embodiment 1 is that, in this embodiment, the base 211 is provided with two support rods 8 arranged along the length of the base 211, and these support rods 8 are arranged in parallel and spaced apart. Each support rod 8 is slidably connected to the base 211 along the width of the base 211. The two support rods 8 correspond to the baffles 212 arranged on both sides of the base 211, with the bottom end of one baffle 212 fixedly installed on the left support rod 8 and the bottom end of the other baffle 212 fixedly installed on the right support rod 8. The base 211 is also provided with a driving assembly 9, which is used to drive the two support rods 8 to slide in opposite directions; therefore, by driving the support rods 8 to slide, the baffles 212 on both sides, along with the rotating rollers 2121, can be moved closer to or further away from each other.

[0058] Reference Figure 7The drive assembly 9 includes a rotary power component 91 and a bidirectional lead screw 92. The rotary power component 91 is a servo motor, which is fixedly mounted on the base 211. The output shaft of the rotary power component 91 is arranged along the width direction of the base 211. The bidirectional lead screw 92 is coaxially fixedly connected to the end of the output shaft of the rotary power component 91, and the threads at both ends of the bidirectional lead screw 92 have opposite directions. The thread helix angle of the thread on the bidirectional lead screw 92 is less than the equivalent friction angle, thus the bidirectional lead screw 92 has a self-locking capability. Each support rod 8 has a connecting block 81 fixedly installed at one end near the bidirectional lead screw 92. The connecting block 81 has a threaded hole adapted to the bidirectional lead screw 92, and the threads of the threaded holes on the connecting blocks 81 at the ends of the two support rods 8 have opposite directions. The two connecting blocks 81 correspond to the two ends of the bidirectional lead screw 92, and each connecting block 81 is threadedly connected to the corresponding end of the bidirectional lead screw 92.

[0059] Therefore, when the rotary power component 91 starts and drives the bidirectional lead screw 92 to rotate, since the threads at both ends of the bidirectional lead screw 92 rotate in opposite directions, the two connecting blocks 81 will slide in opposite directions, causing the two support rods 8 to slide in opposite directions; the output shaft of the rotary power component 91 performs alternating actions of rotating in the forward direction and rotating in the reverse direction, which causes the two support rods 8 to perform alternating actions of moving closer to each other and moving further away from each other, thereby causing the distance between the two support rods 8 to continuously change.

[0060] During the descent of the small guide tube 10, the rotation of the output shaft of the rotating power component 91 can be controlled, causing the baffle 212 to slide back and forth in a small amplitude. This dynamic compression and vibration effectively helps the small guide tube 10 fill the gaps, avoiding jamming or arching during the stacking process, thus making the stacking more compact and uniform. After the required number of small guide tubes 10 have been stacked between the baffles 212 on both sides, simply adjusting the distance between the two support rods 8 to a predetermined value ensures that each pile of small guide tubes 10 can be arranged into a consistent hexagonal pattern, and the size of the hexagon can be varied according to the predetermined value between the two support rods 8, making it more adaptable.

[0061] The implementation principle of Example 2 is as follows: During the process of the small guide tubes 10 falling from the unloading rack 11 into the loading rack 21 in batches, the drive component 9 controls the baffles 212 on both sides to slide synchronously and in opposite directions. Through the dynamic compression of the baffles 212 and the rotating rollers 2121, the small guide tubes 10 are forced to form a dense stack. After the stack is full, the subsequent end alignment, conveying and packaging processes are the same as in Example 1.

[0062] The above are optional embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
