Description

[Technical Field]

[0001] This invention relates to the field of pipe material processing equipment, and more particularly to pipe material packaging devices. [Background Technology]

[0002] After the pipes are manufactured, they need to be packaged, which involves flaw detection, engraving, capping, and packaging before they can be transported. Many of these steps require manual labor, resulting in high labor intensity and low work efficiency for employees. [Summary of the Invention]

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art by proposing a tube packaging device to automate the tube processing and packaging, thereby reducing manpower input.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] A tube packaging device includes two grading and feeding devices, a laser engraving machine, a laser engraving auxiliary device, a radial tube transfer device, a tube capping device, an automatic packaging mechanism, and multiple tube conveying devices. The tube conveying devices are located between the two grading and feeding devices, with the two grading and feeding devices feeding the tubes to the tube conveying devices at intervals. Each grading and feeding device includes a base, a storage rack mounted on the base, a first dispensing frame, and a second dispensing frame. The second dispensing frame has a chain plate assembly on its side for conveying tubes one by one. The tube conveying devices are located below the chain plate assembly. A rack lift connected to the storage rack is mounted on the base. The rack lift drives the storage rack to rise, transferring the tubes from the storage rack to the first dispensing frame. A pusher is located between the first dispensing frame and the second dispensing frame to feed the tubes from the first dispensing frame into the second dispensing frame. The laser engraving auxiliary device is used to clamp and convey the tubes. The laser marking auxiliary device has tube conveying devices at both ends for feeding tubes into or out of the laser marking auxiliary device. The laser marking auxiliary device includes a clamping base and a pair of clamping rollers arranged on the clamping base. The clamping rollers are respectively arranged on both sides of the tube. The radial tube transfer device is used for transverse tube transfer. The radial tube transfer device includes a transverse conveyor frame and a material-pushing rod arranged on the transverse conveyor frame. The transverse conveyor frame is equipped with a power device for driving the material-pushing rod to transversely move the tube. The tube capping device is used to cap both ends of the tube. The tube capping device includes a device body, a four-axis robot on the device body, and a cap-pushing arm located below the four-axis robot. The automatic packaging mechanism is used to package the processed tubes and includes a strapping machine, a material pusher arranged behind the strapping machine, and a laminating machine arranged in front of the strapping machine. The radial tube transfer device is located on the side of the strapping machine.

[0006] Based on the above scheme, the first material distribution frame is provided with a first blocking surface facing the storage rack and a first guide surface inclined towards the second material distribution frame. The first blocking surface blocks and limits the pipe material on the storage rack. The second material distribution frame includes a second blocking surface facing the first material distribution frame and a second guide surface facing the chain plate assembly. The second blocking surface blocks and limits the pipe material on the first material distribution frame. The pusher lifts the pipe material in the first material distribution frame upward until it passes the second guide surface.

[0007] Based on the above scheme, the pushing component includes a pushing support, a pushing lever disposed on the pushing support, and a pushing cylinder connected to and driving the pushing support to rise and fall. The pushing lever includes a blocking member and a guide member connected to each other. The guide member has an inclined surface arranged from the first dispensing frame toward the second dispensing frame so that the lifted pipe rolls off the guide member onto the second dispensing frame. The blocking member stops the pipe on the first dispensing frame from moving below the guide member when the guide member lifts the pipe.

[0008] Based on the above scheme, the pipe material conveying device includes a conveying frame and multiple sets of conveying rollers mounted on the conveying frame. Multiple roller mounting seats are arranged at intervals along the length of the conveying frame. The conveying rollers are rotatably mounted on the roller mounting seats. A guide mechanism is provided on the side of the roller mounting seats. The guide mechanism includes a pair of guide plates.

[0009] Based on the above scheme, the conveyor frame is provided with a pipe diameter changing clamping mechanism for adjusting the spacing between guide plates. The pipe diameter changing clamping mechanism includes a driver and a first limiting slide rail disposed on the guide base. The guide plate includes a sliding seat, which is slidably mounted on the first limiting slide rail. The driver drives the sliding seat to slide along the first limiting slide rail to adjust the position of the guide plate. The pipe diameter changing clamping mechanism also includes a pair of connecting rods. The connecting rods are disposed along the length direction of the conveyor frame and connect to at least two sliding seats. The driver connects to the connecting rods to drive the connecting rods to move along the width direction of the conveyor frame.

[0010] Based on the above scheme, the driver includes a motor, a lead screw driven by the motor, and a nut piece threadedly installed on the lead screw. The lead screw is provided with two nut pieces to connect to a connecting rod respectively. The lead screw is provided with threads at both ends with opposite helical directions to drive the two nut pieces to move towards or away from each other.

[0011] Based on the above scheme, the power unit includes a third power motor and a transmission device that is connected to the third power motor. The transmission device is connected to the material feeding rod through a connecting block. One end of the connecting block is connected to the transmission device, and the other end is rotatably connected to the material feeding rod. The transverse conveyor frame is also provided with a circular slider. The material feeding rod is provided with a guide groove that slides with the circular slider. The material feeding rod includes a material feeding rod body. One end of the material feeding rod body is provided with a material feeding hook. When the material feeding rod is reset from below the material feeding rod body, the material feeding hook positions the material feeding tube on the material feeding rod body.

[0012] Based on the above scheme, the four-axis robot includes a robot body, and the mechanical gripper is connected to the robot body via a telescopic rod. The mechanical gripper includes a gripper base and a pair of clamping plates disposed below the gripper base. The mechanical gripper clamps the straight tube plug between the clamping plates. The pusher arm includes a mounting base disposed on the device body and a pusher cylinder disposed on the mounting base. The end of the pusher cylinder is provided with a pusher plate, which is disposed at the center between the two clamping plates.

[0013] Based on the above scheme, the strapping machine includes a strapping frame, a clamping port disposed on the strapping frame, a transmission roller and a strapping unit rotatably mounted on the strapping frame, the tube being supported on the transmission roller, the clamping port including a fixed clamping end and a movable clamping end, the movable clamping end and the fixed clamping end including a clamping push plate, the clamping push plate being provided with guide ribs, the guide ribs including vertical ribs and arc-shaped ribs connected to each other from top to bottom.

[0014] Based on the above scheme, the pusher includes a pusher frame and a sliding mechanism on the pusher frame. The sliding mechanism is provided with a top pusher plate. The sliding mechanism includes a fixed track and multiple fixed bases fixedly installed on the fixed track. Fixed slides are provided on the fixed bases. Sliding members are slidably installed on the fixed slides. The top pusher plate is installed at the end of the sliding members. A drive frame is fixedly installed on the pusher frame near the strapping machine. A motor and a gear driven by the motor are installed on the drive frame. The gear meshes with the sliding members.

[0015] The beneficial effects of this invention are:

[0016] This invention discloses a tube packaging device that can automate the processing and packaging of tubes.

[0017] In the initial stage of equipment operation, pipes are stacked in a storage rack. The rack is lifted by a hoist, and after rising a certain distance, some of the pipes on it enter the first sorting rack, achieving the first sorting. A pusher then feeds some pipes from the first sorting rack to the second sorting rack, achieving the second sorting. The pipes on the second sorting rack roll towards the chain conveyor assembly under gravity, and are then individually conveyed by the chain conveyor to the pipe conveyor device. This two-stage sorting divides the large pile of pipes into smaller portions, preventing stacking during transport and ensuring smooth automated transport. A laser engraving machine is used to engrave on the pipe surface. A laser engraving auxiliary device clamps the pipes during engraving to prevent uneven or blurry engravings caused by pipe movement. The tube conveying device, located in front of the laser marking auxiliary device, transports the tube material onto the device. Once inside, the tube is clamped by clamping rollers on both sides. This clamping action restricts the tube's circumferential rotation and radial displacement, ensuring smooth transport and facilitating the marking process. After laser marking, the tube is capped by a tube capping device and then automatically packaged by a radial tube transfer device.

[0018] Furthermore, the first material distribution frame is provided with a first blocking surface facing the storage rack and a first guide surface inclined towards the second material distribution frame. The first blocking surface blocks and limits the pipe material on the storage rack. The second material distribution frame includes a second blocking surface facing the first material distribution frame and a second guide surface facing the chain plate assembly. The second blocking surface blocks and limits the pipe material on the first material distribution frame. The pusher lifts the pipe material in the first material distribution frame upward until it passes the second guide surface. The tubular material located on the storage rack is held on the storage rack by the first blocking surface. As the material rack elevator drives the storage rack upward, the tubular material gradually passes the first blocking surface of the first material distribution frame and falls onto the first guide surface under the action of gravity. The tubular material rolls along the first guide surface. Under the blocking of the second guide surface, the tubular material is held on the first material distribution frame until the pusher drives the tubular material in the first material distribution frame to rise until the tubular material passes the second blocking surface and falls onto the second guide surface under the action of gravity, and is conveyed towards the chain plate assembly along the second guide surface.

[0019] Furthermore, the pushing component includes a pushing support, a pushing lever disposed on the pushing support, and a pushing cylinder connected to and driving the pushing support to rise and fall. The pushing lever includes a blocking member and a guide member connected to each other. The guide member has an inclined surface arranged from the first dispensing frame toward the second dispensing frame so that the lifted pipe rolls off the guide member onto the second dispensing frame. The blocking member stops the pipe on the first dispensing frame from moving below the guide member when the guide member lifts the pipe. During the conveying of pipe materials, the pushing cylinder drives the pushing support to move upward, and the guide of the pushing lever drives the pipe materials on the first distributing frame to move upward. During the upward movement, the pipe materials on the guide are blocked by the second blocking surface and remain on the guide until they pass the second blocking surface. After that, the pipe materials roll off the guide onto the second distributing frame. During the upward movement of the pushing lever, the blocking component keeps blocking the pipe materials on the first distributing frame to prevent the pipe materials on the first distributing frame from changing position. The pipe materials on the first guide surface will continue to roll along the first guide surface to the top of the guide until the pushing lever retracts to below the first guide surface.

[0020] Furthermore, the pipe conveying device includes a conveyor frame and multiple sets of conveying rollers mounted on the conveyor frame. Multiple roller mounting seats are spaced apart along the length of the conveyor frame. The conveying rollers are rotatably mounted on the roller mounting seats. A guiding mechanism is provided on the side of each roller mounting seat, and the guiding mechanism includes paired guide plates. During the conveying process on the pipe conveying device, the pipe is placed on the conveying rollers. The conveying rollers can rotate relative to the roller mounting seats to reduce the friction between the pipe and the conveying rollers. The pipe conveying device is used in pipe processing equipment as a device for conveying pipes between two pipe processing machines. To reduce radial displacement of the pipe, a guiding mechanism is provided on the side of the roller mounting seats to guide the pipe into the conveyor frame, making the pipe conveying process more stable.

[0021] Furthermore, the conveyor frame is provided with a pipe diameter changing clamping mechanism for adjusting the spacing between guide plates. The pipe diameter changing clamping mechanism includes a driver and a first limiting slide rail disposed on the guide base. The guide plate includes a sliding seat, which is slidably mounted on the first limiting slide rail. The driver drives the sliding seat to slide along the first limiting slide rail to adjust the position of the guide plate. The pipe diameter changing clamping mechanism also includes a pair of connecting rods. The connecting rods are disposed along the length direction of the conveyor frame and connect to at least two sliding seats. The driver connects to the connecting rods to drive the connecting rods to move along the width direction of the conveyor frame. To accommodate pipes of different specifications, the spacing between the two guide plates can be adjusted using a pipe diameter changing clamping mechanism. This provides good guidance for pipes of various specifications. The sliding seat is slidably mounted on the first limit slide rail to limit the guide plate along the length of the conveyor frame. The pipe diameter changing clamping mechanism can adjust the position of the guide plate on the first limit slide rail, thus allowing the spacing between the guide plates to be adjusted according to the pipe specifications. The connecting rod can connect multiple sliding seats simultaneously. When the position of the connecting rod changes in the width direction of the conveyor frame, the spacing between multiple pairs of guide plates can be changed simultaneously, and the degree of spacing change is consistent. In addition, through the connection between the driver and the connecting rod, when the driver is stationary, the position of the guide plate will also remain stationary along with the connecting rod to prevent changes in the spacing between the guide plates during pipe conveying.

[0022] Furthermore, the drive unit includes a motor, a lead screw driven by the motor, and nuts threadedly mounted on the lead screw. The lead screw has two nuts, each connected to a connecting rod. The lead screw has threads with opposite helical directions at both ends to drive the two nuts to move towards or away from each other. When the lead screw rotates, the two nuts can move towards or away from each other to decrease or increase the distance between the two guide plates. The direction of movement of the nuts is related to the rotation direction of the lead screw. With this configuration, only one motor is needed to simultaneously change the distance between the two guide plates, and the guide plates move the same distance. This allows the pipe material to be conveyed above the center position of the conveyor roller, which is beneficial for pipe material conveying and reduces radial positional deviation when the pipe material enters the conveyor frame or is fed to the next device.

[0023] Furthermore, the power unit includes a third power motor and a transmission device that is driven by the third power motor. The transmission device is connected to the material-feeding rod through a connecting block. One end of the connecting block is connected to the transmission device, and the other end is rotatably connected to the material-feeding rod. The transverse conveyor frame is also provided with a circular slider. The material-feeding rod is provided with a guide groove that slides with the circular slider. The material-feeding rod includes a material-feeding rod body. One end of the material-feeding rod body is provided with a material-feeding hook. When the material-feeding rod is reset from below the material tube, the material-feeding hook positions the material tube on the material-feeding rod body. During the lateral movement of the pipe, the third power motor starts and transmits power to the transmission device. The transmission device drives the connecting block to rotate. During the rotation of the connecting block, it pushes the material-feeding rod to move towards the pipe. At the same time, the connecting block also drives the material-feeding rod to move downward so that it is below the pipe. The circular slider slides in the guide groove to position the material-feeding rod and prevent it from rotating independently relative to the connecting block, which would affect the conveying of the pipe. As the connecting block continues to rotate, it drives the material-feeding rod to reset. When the material-feeding rod resets, it moves the pipe... The material moves upward, causing the tube to fall onto the feeding rod and move along its surface, thus achieving radial transmission of the tube. The feeding hook protrudes from the feeding rod and, as the feeding rod moves upward, it can move the tube along with it to transmit the tube. The tube on the feeding rod is held in place by the limiting action of the feeding hook. When the feeding rod returns to its original position, the end with the feeding hook is higher than the other end, allowing the tube to slide off from the other end of the feeding rod, completing the lateral transfer of the tube.

[0024] Furthermore, the four-axis robot includes a robot body, and the mechanical gripper is connected to the robot body via a telescopic rod. The mechanical gripper includes a gripper base and a pair of clamping plates disposed below the gripper base. The mechanical gripper clamps the straight tube plug between the clamping plates. The pusher arm includes a mounting base disposed on the device body and a pusher cylinder disposed on the mounting base. The end of the pusher cylinder is provided with a pusher plate, which is disposed at the center between the two clamping plates. The mechanical clamping arm can be adjusted vertically by the telescopic rod to lower and clamp the straight tube plug on the vibrating plate. The position of the mechanical clamping arm can also be adjusted according to the tube specifications to ensure that the straight tube plug is aligned with the tube axis, avoiding misalignment during the plugging process that could lead to plug breakage or plugging failure. The push cylinder can drive the push plate to move, pushing the straight tube plug held by the clamping plate towards the tube, so that the straight tube plug is inserted into the tube. The push plate can cover a large area, so even when processing tubes of different sizes, the straight tube plug can be pushed in smoothly.

[0025] Furthermore, the strapping machine includes a strapping frame, a clamping port disposed on the strapping frame, a transmission roller rotatably mounted on the strapping frame, and a strapping unit. The tube is supported on the transmission roller. The clamping port includes a fixed clamping end and a movable clamping end. The movable clamping end and the fixed clamping end include clamping push plates. The clamping push plates are provided with guide ribs. The guide ribs include vertical ribs and arc-shaped ribs connected to each other from top to bottom. The tubing is laterally conveyed to the strapping machine frame by the radial tubing transfer device. The tubing is placed on the drive rollers on the strapping machine frame. When the number of tubing reaches a certain requirement, the clamping movable end moves toward the clamping fixed end to clamp the tubing, so that multiple tubing are stacked. The strapping machine bundles the stacked tubing. The clamping push plate can radially limit the tubing to prevent it from falling off the strapping machine frame from the side of the clamping port when clamping. The clamping ribs have a guiding effect on the tubing. The arc-shaped ribs located at the bottom can guide the tubing to move upward along the surface of the arc-shaped ribs as the clamping movable end and the clamping fixed end gradually approach each other, making it easier to stack multiple tubing.

Detailed Implementation Methods

[0064] The technical solutions of the embodiments of the present invention will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present invention.

[0065] The terms "exemplary" and "some embodiments" used below are meant to be "used as examples, embodiments, or illustrations," and any embodiment described as "exemplary" is not necessarily to be construed as superior to or better than other embodiments. Numerous specific details are set forth in the following detailed description to better illustrate the invention, and those skilled in the art will understand that this disclosure can be practiced without certain specific details.

[0066] Reference Figures 1 to 27The present invention discloses a tube packaging device, including two graded feeding devices 10, a laser engraving machine, a laser engraving auxiliary device 30, a radial tube transfer device 50, a tube plug device 60, an automatic packaging mechanism 70, and multiple tube conveying devices 20, so as to realize the automated processing and packaging of tubes.

[0067] The graded feeding device 10 is used to grade and convey the pipe material, gradually dividing the large pile of pipe material into small piles, several pipes, and single pipes, and then feeding the pipe material one by one into the pipe material conveying device 20 for conveying. The pipe material conveying device 20 is provided between the two graded feeding devices 10, and the two graded feeding devices 10 convey the pipe material to the pipe material conveying device 20 at intervals, thereby improving the conveying efficiency and processing speed of the pipe material.

[0068] The graded feeding device 10 includes a base 100, on which a storage rack 110, a first distributing frame 120, and a second distributing frame 130 are provided. A pusher 140 is provided between the first distributing frame 120 and the second distributing frame 130 to feed the pipe material on the first distributing frame 120 into the second distributing frame 130. The side of the second distributing frame 130 is also provided with a chain plate assembly 150 for conveying the pipe material one by one. The pipe material on the second distributing frame 130 rolls from top to bottom toward the chain plate assembly 150. A material rack lift 111 connected to the storage rack 110 is provided on the base 100. The material rack lift 111 drives the storage rack 110 to rise so that the pipe material on the storage rack 110 is transferred to the first distributing frame 120.

[0069] The graded feeding device 10 enables automatic feeding of pipe materials. In the initial stage of equipment operation, pipe materials are stacked in the storage rack 110. The rack is driven to rise and fall by the rack lift 111. After the rack rises a certain distance, some of the pipe materials stacked on it enter the first sorting frame 120, achieving the first sorting. The pusher 140 then feeds some of the pipe materials from the first sorting frame 120 to the second sorting frame 130, achieving the second sorting. The pipe materials on the second sorting frame 130 roll towards the chain plate assembly 150 under gravity, allowing them to be conveyed one by one by the chain plate assembly 150. Through these two sorting processes, the large pile of pipe materials is divided into smaller portions for conveying, preventing stacking during pipe transport and ensuring uninterrupted automated transport.

[0070] The pipe conveying device 20 includes a conveyor frame 200 and multiple sets of conveying rollers 210 mounted on the conveyor frame 200. Multiple roller mounting seats 211 are spaced apart along the length of the conveyor frame 200. The conveying rollers 210 are rotatably mounted on the roller mounting seats 211. A guide mechanism 220 is provided on the side of the roller mounting seat 211. The guide mechanism 220 includes a pair of guide plates 221 and a guide base 222 mounted on the conveyor frame 200. A conveying gap 201 with an open upper end is formed between the two guide plates 221. The end of the chain plate assembly 150 is set corresponding to the conveying gap 201. The roller mounting seat 211 is fixed on the guide base 222. The guide plate 221 is set corresponding to the center of the roller. The conveying rollers 210 are straight cylindrical rollers. A pipe diameter clamping mechanism 230 for adjusting the spacing between the guide plates 221 is provided on the conveyor frame 200.

[0071] After the tube material is conveyed to the end position of the chain plate assembly 150 by the grading and feeding device 10, it falls downwards and through the conveying gap 201 between the two guide plates 221 into the tube material conveying device 20. The tube material conveying device 20 can keep the tube material stable during the conveying process, and it can convey tube materials of different specifications. Even if the tube materials have different specifications, they can still be conveyed stably. During the conveying process, the tube material is placed on the conveying roller 210. The conveying roller 210 can rotate relative to the roller mounting seat 211 to reduce the friction between the tube material and the conveying roller 210. The tube material conveying device 20 is used in tube material processing equipment as a device for conveying tube materials between two tube material processing equipment. In order to reduce the radial positional deviation of the tube material, a guide mechanism 220 is provided on the side of the roller mounting seat 211 to guide the tube material into the conveyor frame 200, making the tube material conveying more stable. Since the size and specifications of the tube material are not fixed, the conveying roller 210 is used to guide the tube material into the conveyor frame 200. 10 is set as a straight cylinder to accommodate pipes of various specifications. However, this means that the conveying roller 210 does not have a guiding or radial limiting function for the pipe. The guiding mechanism 220 includes a pair of guide plates 221. The guide plates 221 are set on both sides of the pipe to radially limit the pipe, which can effectively guide the pipe on the conveyor frame 200. In order to accommodate different pipes, the distance between the two guide plates 221 can be adjusted by the pipe diameter changing clamping mechanism 230, so that it can have a good guiding effect for pipes of various specifications.

[0072] Specifically, the storage rack 110 includes a storage frame 112, the storage frame 112 includes a bottom baffle 113, the bottom baffle 113 is connected to a side baffle 114 at the end away from the first material distribution frame 120, and a support beam 115 for supporting the pipe material is provided on the bottom baffle 113. The height of the support beam 115 gradually decreases from the side baffle 114 toward the first material distribution frame 120.

[0073] The storage frame 112 can be used to hold the pipe material. The side baffle 114 is used to limit the pipe material to prevent it from falling off the side of the storage frame 112 onto the base 100. The side of the storage frame 112 facing the first distribution frame 120 does not have a limiting mechanism for the pipe material. In this way, as the storage frame 110 is lifted upward, the pipe material can move towards the first distribution frame 120 under its own gravity and the guidance of the support beam 115. After part of the pipe material is transferred to the first distribution frame 120, the material rack elevator 111 drives the storage frame 110 to move downward to stop the pipe material from being conveyed towards the first distribution frame 120.

[0074] The material rack lift 111 is located below the bottom baffle 113. Multiple sets of material rack lifts 111 are spaced apart along the length of the storage rack 110, with each set including at least two material rack lifts 111. By setting multiple sets of material rack lifts 111, the storage rack 110 can be kept stable along its length, thus avoiding a large positional difference between the two ends of the pipe when it is conveyed to the first distribution frame 120, which would affect the conveying process of the pipe and reduce collisions during the conveying process. Each set of material rack lifts 111 includes at least two material rack lifts 111, which can ensure the stability of the storage rack 110 and reduce the tilting of the storage rack 110, so as to ensure that the pipe can be conveyed smoothly.

[0075] The base 100 has a guide rail 101 located on the side of the side baffle 114, and the storage rack 110 has a guide slider 102 that slides with the guide rail 101. The cooperation between the guide rail 101 and the guide slider 102 makes the lifting process of the storage rack 110 smoother and reduces the jerking sensation during the lifting process.

[0076] The first dispensing frame 120 is provided with a first blocking surface 121 facing the storage rack 110 and a first guide surface 122 inclined towards the second dispensing frame 130. The first blocking surface 121 blocks and limits the pipe material on the storage rack 110. The second dispensing frame 130 includes a second blocking surface 131 facing the first dispensing frame 120 and a second guide surface 132 facing the chain plate assembly 150. The second blocking surface 131 blocks and limits the pipe material on the first dispensing frame 120. The pusher 140 lifts the pipe material in the first dispensing frame 120 upward until it passes the second guide surface 132.

[0077] The tubular material located on the storage rack 110 is held on the storage rack 110 by the blocking action of the first blocking surface 121. As the rack lift 111 drives the storage rack 110 upward, the tubular material gradually passes the first blocking surface 121 of the first distributing frame 120 and falls onto the first guide surface 122 under the action of gravity. The tubular material rolls along the first guide surface 122 and is held on the first distributing frame 120 by the blocking action of the second guide surface 132 until the pusher 140 drives the tubular material in the first distributing frame 120 to rise until the tubular material passes the second blocking surface 131 and falls onto the second guide surface 132 under the action of gravity, and is conveyed towards the chain plate assembly 150 along the second guide surface 132.

[0078] To achieve automated feeding, when the number of tubes on the first feeding frame 120 decreases, it is necessary to replenish them. The base 100 is equipped with an upper detection sensor 124 and a lower detection sensor 125 to detect the number of tubes on the first feeding frame 120. In the vertical plane, the upper detection sensor 124 is located at one end of the first guide surface 122 near the first blocking surface 121, and the lower detection sensor 125 is located at one end of the first guide surface 122 near the second feeding frame 130. The upper detection sensor 124 and the lower detection sensor 125 can respectively detect whether there is pipe material on the first guide surface 122 near the first blocking surface 121 and the end near the second distributing frame 130, thereby determining whether there is enough pipe material on the first distributing frame 120. When the upper detection sensor 124 detects the presence of pipe material, it means that there is enough pipe material on the first distributing frame 120, and the material rack elevator 111 does not need to drive the storage rack 110 to transfer pipe material, so as to avoid the situation of pipe material stacking on the first distributing frame 120. When the lower detection sensor 125 does not detect the presence of pipe material, it means that there is not enough pipe material on the first distributing frame 120, and the material rack elevator 111 needs to be started in time to replenish the pipe material on the first distributing frame 120.

[0079] The pusher 140 includes a pusher support 141, a pusher lever 142 disposed on the pusher support 141, and a pusher cylinder 143 connected to and driving the pusher support 141 to rise and fall. The pusher lever 142 includes a blocking member 144 and a guide member 145 connected to each other. The guide member 145 has an inclined surface disposed from the first dispensing frame 120 toward the second dispensing frame 130 so that the lifted pipe rolls from the guide member 145 onto the second dispensing frame 130. The blocking member 144 stops the pipe on the first dispensing frame 120 from moving below the guide member 145 when the guide member 145 lifts the pipe.

[0080] During the conveying of pipe material, the pusher cylinder 143 drives the pusher support 141 to move upward, and the guide 145 of the pusher lever 142 drives the pipe material on the first distribution frame 120 to move upward. During the upward movement, the pipe material on the guide 145 is blocked by the second blocking surface 131 and remains on the guide 145 until it passes the second blocking surface 131 and rolls off the guide 145 onto the second distribution frame 130. During the upward movement of the pusher lever 142, the blocking component 144 keeps blocking the pipe material on the first distribution frame 120 to prevent the pipe material on the first distribution frame 120 from changing position until the pusher lever 142 retracts to below the first guide surface 122, at which point the pipe material on the first guide surface 122 will continue to roll along the first guide surface 122 to above the guide 145.

[0081] The pusher support 141 is equipped with a changing cylinder 146 that drives the pusher lever 142 to move toward the first material distribution frame 120 or the second material distribution frame 130. There are two changing cylinders 146, which are used to drive the pusher lever 142 to move toward the first material distribution frame 120 and the second material distribution frame 130, respectively. By setting two changing cylinders 146, the control is more accurate and the stroke control effect is better. The changing cylinder 146 can drive the pusher lever 142 to adjust the position of the pusher lever 142 relative to the first material distribution frame 120 and the second material distribution frame 130, thereby changing the projected area of ​​the tube material on the guide member 145 on the first material distribution frame 120. That is, it increases or decreases the effective length of the guide member 145 in the process of lifting the tube material. In order to ensure that the equipment can operate better, the number of tube materials conveyed each time needs to be fixed. When the tube material size is different, the number of tube materials that the guide member 145 of the same length can lift is different. The position of the pusher lever 142 is adjusted according to the size of the tube material, thereby fixing the number of tube materials lifted by the pusher member 140 each time.

[0082] The pusher 140 is used to drive the pipe material on the first dispensing frame 120 to move upward. The first dispensing frame 120 and the second dispensing frame 130 are arranged adjacent to each other. In order to prevent the pipe material from falling between them, the first dispensing frame 120 and the second dispensing frame 130 are kept in a close fit. For this purpose, multiple first dispensing frames 120 and multiple second dispensing frames 130 are arranged at intervals along the length direction of the base 100. The multiple first dispensing frames 120 and multiple second dispensing frames 130 are arranged one-to-one. A first gap 123 is formed between two adjacent first dispensing frames 120, and a second gap 133 is formed between two adjacent second dispensing frames 130 that communicates with the first gap 123. The pusher 140 is disposed in the first gap 123 and the second gap 133, so that the lifting and lowering movement of the pusher 140 is not obstructed.

[0083] A conveyor belt assembly 160 is also provided between the second sorting frame 130 and the chain plate assembly 150. The conveyor belt assembly 160 feeds the pipes one by one onto the chain plate assembly 150. The conveyor belt assembly 160 is used to transport the pipes conveyed to the second sorting frame 130 to the chain plate assembly 150. The conveyor belt assembly 160 can transport the pipes to the chain plate assembly 150 at a uniform speed, realizing the one-to-one transport of the pipes. The conveyor belt assembly 160 is actually the third-level sorting. The pusher 140 feeds multiple pipes onto the second sorting frame 130 at a time. The conveyor belt assembly 160 is arranged in a horizontal direction. The pipes rolling from the second sorting frame 130 onto the conveyor belt assembly 160 can be buffered and their speed reduced. They can also move at a uniform speed with the conveyor belt assembly 160, avoiding the pipes from falling onto the chain plate assembly 150 and stacking up.

[0084] The automatic feeding device also includes an anti-stacking mechanism 170. The anti-stacking mechanism 170 includes anti-stacking bases 171 disposed on both sides of the conveyor belt assembly 160 and a blocking member 172 disposed above the conveyor belt assembly 160. A screw assembly 173 connecting the blocking member 172 is provided on the anti-stacking bases 171. The screw assembly 173 adjusts the distance between the blocking member 172 and the conveyor belt assembly 160 according to the pipe specifications. The anti-stacking mechanism 170 prevents pipe stacking on the conveyor belt assembly 160. As the conveyor belt assembly 160 moves, the pipes gradually approach the chain plate assembly 150. When the pipes pass the blocking member 172, they pass under the blocking member 172. If pipe stacking occurs, the uppermost pipes are blocked by the blocking member 172, preventing them from maintaining a stacked state. According to the pipe specifications, the screw assembly 173 can adjust the height of the blocking member 172 to maintain a suitable distance between the blocking member 172 and the conveyor belt assembly 160.

[0085] The chain plate assembly 150 includes a chain plate frame 151, a chain 152 mounted on the chain plate frame 151, and a chain plate driver 153 that drives the chain 152. The chain 152 has multiple conveyor plates 154, with a conveying area 155 for carrying tubular material formed between two connected conveyor plates 154. The chain plate driver 153 provides power for the transmission of the chain 152. During the transmission of the chain 152, the tubular material falls into the conveying area 155 between two connected conveyor plates 154, and can then move along with the transmission of the chain 152.

[0086] The chain plate assemblies 150 located on both sides of the pipe conveying device 20 are set with corresponding conveying gaps 201. The two chain plate assemblies 150 do not convey pipes at the same time, so there will be no conveying interference between the two chain plate assemblies 150, and they will not affect each other and thus affect the normal operation of the equipment. Of course, in order to ensure the smooth conveying of pipes, the chain plate assemblies 150 on both sides can be staggered along the length of the conveyor frame 200.

[0087] The aforementioned pipe diameter changing clamping mechanism 230 includes a driver 231 and a first limiting slide rail 223 disposed on the guide base 222. The guide plate 221 includes a sliding seat 224, which is slidably mounted on the first limiting slide rail 223. The driver 231 drives the sliding seat 224 to slide along the first limiting slide rail 223 to adjust the position of the guide plate 221. The sliding seat 224 is slidably mounted on the first limiting slide rail 223 to limit the guide plate 221 in the length direction of the conveyor frame 200. The pipe diameter changing clamping mechanism 230 can adjust the position of the guide plate 221 on the first limiting slide rail 223, thereby allowing the spacing between the guide plates 221 to be adjusted according to the pipe specifications.

[0088] The pipe diameter changing clamping mechanism 230 also includes a pair of connecting rods 232. The connecting rods 232 are located below the conveyor rollers 210 and are arranged along the length of the conveyor frame 200, connecting at least two sliding seats 224. The driver 231 is connected to the connecting rods 232 to drive the connecting rods 232 to move along the width of the conveyor frame 200. The connecting rods 232 can connect multiple sliding seats 224 simultaneously. When the position of the connecting rods 232 changes in the width of the conveyor frame 200, the spacing between multiple pairs of guide plates 221 can be changed simultaneously, and the degree of spacing change is consistent. In addition, through the connection between the driver 231 and the connecting rods 232, when the driver 231 is stationary, the position of the guide plates 221 will also remain stationary along with the connecting rods 232, so as to avoid changes in the spacing between the guide plates 221 during the pipe material conveying process.

[0089] Specifically, the driver 231 includes a motor, a lead screw 233 driven by the motor, and a nut 234 threadedly mounted on the lead screw 233. The lower end of the nut 234 abuts against the conveyor frame 200 to restrict the circumferential rotation of the nut 234. The lead screw 233 is provided with two nuts 234 to connect to a connecting rod 232 respectively. The lead screw 233 is provided with threads at both ends with opposite helical directions to drive the two nuts 234 to move towards or away from each other. When the lead screw 233 rotates, the two nuts 234 on the lead screw 233 can move towards or away from each other to reduce or increase the distance between the two guide plates 221. The direction of movement of the nuts 234 is related to the direction of rotation of the lead screw 233. With this setting, only one motor is needed to simultaneously change the distance between the two guide plates 221, and the moving distance of the guide plates 221 is the same, so that the tube can be conveyed above the center position of the conveying roller 210, which is beneficial to the conveying of the tube and reduces the radial positional deviation when the tube enters the conveyor frame 200 or is sent to the next device.

[0090] The guiding mechanism 220 also includes a guide post 225, and a guide plate 221 is mounted on the guide post 225. The guide plate 221 is inclined outward from the guide post 225 toward the conveyor frame 200. The inclined guide plate 221 allows for a certain positional deviation of the tube in the radial direction. The guide plate 221 guides the tube toward the center position of the conveyor roller 210. During the tube conveying process, there will be a certain amount of contact between the tube and the guide post 225. The guide post 225 has a cylindrical structure, which reduces damage to the surface of the tube.

[0091] The conveyor frame 200 is also equipped with a power motor 212. The ends of two adjacent conveyor rollers 210 are connected by a first conveyor belt 213. The conveyor rollers 210 located at the ends are connected to the power motor 212 via the first conveyor belt 213. The power motor 212 can drive the first conveyor belt 213 to drive the conveyor rollers 210 located at the ends to rotate. Power is transmitted between the conveyor rollers 210 via the first conveyor belt 213, so that all the conveyor rollers 210 can rotate to convey the pipe material.

[0092] The laser marking machine is used to mark the surface of the tube material during the tube material conveying process. The laser marking auxiliary device 30 is located on the side of the laser marking machine and is used to clamp and convey the tube material to avoid uneven or blurry markings caused by the tube material shaking. The two ends of the laser marking auxiliary device 30 are equipped with tube material conveying devices 20, which are used to feed the tube material into or out of the laser marking auxiliary device 30. The side of the tube material conveying device 20 at the rear end of the laser marking auxiliary device 30 is equipped with a defective product collection rack 400. A marking inspection probe is provided between the defective product collection rack 400 and the tube material conveying device 20 to screen tube materials that are not marked.

[0093] The laser marking auxiliary device 30 includes a clamping base 300 and a pair of clamping roller groups 310 arranged on the clamping base 300. The clamping roller groups 310 are respectively arranged on both sides of the tube. The clamping base 300 is rotatably mounted with a support roller 320 for supporting the tube. The clamping roller groups 310 are slidably mounted on the clamping base 300. The clamping base 300 is provided with a clamping driver 330 for driving the clamping roller groups 310 to adjust the distance between the two sets of clamping roller groups 310.

[0094] The tube conveying device 20, located in front of the laser marking auxiliary device 30, conveys the tube material onto the laser marking auxiliary device 30. After the tube material enters the laser marking auxiliary device 30, it is conveyed to the clamping base 300 and clamped by the clamping roller assembly 310 located on both sides of the tube material. The support roller 320 supports the tube material and rolls along with the tube material during conveyance. Under the clamping action, the clamping roller assembly 310 can restrict the circumferential rotation and radial displacement of the tube material, so that the tube material is conveyed smoothly to ensure that the marking process can proceed smoothly. The clamping driver 330 can drive the clamping roller assembly 310 to slide on the clamping base 300 and adjust the distance between the two sets of clamping roller assemblies 310 to facilitate the insertion of the tube material between the two sets of clamping roller assemblies 310. When processing tube materials of different specifications, the distance between the two sets of clamping roller assemblies 310 can also be adjusted accordingly.

[0095] After the engraving is completed, the tube material enters the tube material conveying device 20 behind the laser engraving auxiliary device 30 and continues to be conveyed. After the tube material leaves the laser engraving auxiliary device 30, the engraving on the surface of the tube material is inspected by the engraving inspection probe to determine whether the engraving meets the standard. Tube materials that fail the inspection will be screened and stored in the non-conforming product collection rack 400, which can prevent non-conforming products from entering the market.

[0096] A conveying gap 201 for conveying tube material is defined between two pairs of guide plates 221, and a conveying channel 301 for conveying tube material is defined between two sets of clamping rollers 310. By setting the center lines of the conveying gap 201 and the conveying channel 301 in the tube material length direction on the same plane, the tube material can be conveyed in the tube material conveying device 20-laser marking auxiliary device 30-tube material conveying device 20, reducing the radial displacement of the tube material, making the tube material conveying more stable, reducing the collision between the tube material and the tube material conveying device 20 and the laser marking auxiliary device 30, and avoiding affecting the quality of the tube material.

[0097] The clamping roller assembly 310 includes a roller base 311 and two clamping rollers 312 mounted on the roller base 311. The clamping rollers 312 of the two sets of clamping roller assemblies 310 are staggered along the length of the pipe. Multiple clamping rollers 312 provide better radial restraint of the pipe, resulting in greater stability during pipe transport. The staggered arrangement of the clamping rollers 312 reduces the risk of pipe diameter changes due to compression by the clamping rollers 312, and the smaller spacing between adjacent clamping rollers 312 along the length further enhances pipe stability.

[0098] The roller base 311 is equipped with a roller bracket 313, and the clamping roller 312 is rotatably mounted on the roller bracket 313. The clamping roller assembly 310 also includes a second power motor 314 for driving the clamping roller 312 to rotate. The second power motor 314 can drive the clamping roller 312 to rotate, providing power for conveying the tube material. In this way, printing can be performed while transmission is being carried out, resulting in higher tube material processing efficiency. The printing machine also does not need to be moved.

[0099] Specifically, the second power motor 314 is connected to the first transmission wheel 315, and the lower end of the clamping roller 312 is provided with a second transmission wheel 316. The first transmission wheel 315 and the second transmission wheel 316 are driven by a second transmission belt 317. The second power motor 314 drives the first transmission wheel 315 to rotate, and under the drive of the second transmission belt 317, the two clamping rollers 312 can rotate simultaneously. In this way, only one second power motor 314 is needed to drive the two clamping rollers 312 to rotate.

[0100] To better limit the radial movement of the tube, the clamping rollers 312 taper downwards. The tube is restricted from downward displacement by the support rollers 320, and the upward displacement of the tube is better restricted by the clamping rollers 312 of this shape.

[0101] To enhance the stability of the pipe material during transport, the clamping roller 312 is a silicone friction wheel. Made of silicone-based materials, the clamping roller 312 has a certain degree of elasticity, causing minimal damage to the pipe material. It also has a high coefficient of friction with the pipe material, preventing slippage between them through the friction. This also makes the pipe material more stable and improves the circumferential positioning effect of the clamping roller 312.

[0102] The clamping base 300 is also provided with a second limiting slide rail 331. The clamping roller assembly 310 includes a limiting slider 332 that slides with the second limiting slide rail 331. The clamping driver 330 is a linear driver connected to the clamping roller assembly 310. Through the cooperation between the limiting slider 332 and the second limiting slide rail 331, the clamping roller assembly 310 can only have displacement along the second limiting slide rail 331. Through the clamping driver 330, the position of the clamping roller assembly 310 can be kept unchanged during the pipe material conveying process.

[0103] During the engraving process, the tube material conveying device 20 located in front of the laser engraving auxiliary device 30 provides power to move the tube material toward the laser engraving auxiliary device 30, while the tube material conveying device 20 located behind the laser engraving auxiliary device 30 provides power to move the tube material away from the laser engraving auxiliary device 30.

[0104] The automatic pipe capping device includes three radial pipe transfer devices 50, two pipe capping devices 60, and two fixing devices. The fixing devices are located between two adjacent radial pipe transfer devices 50. The radial pipe transfer devices 50 are used to radially transfer the pipe, so that the pipe moves laterally from the pipe transfer device 20 to the fixing device and from one fixing device to another. The pipe capping devices 60 are set corresponding to the fixing devices and perform capping operations on the pipe after it is transferred to the fixing device. The fixing devices are used to keep the pipe fixed during the capping operation. The two pipe capping devices 60 respectively cap both ends of the pipe to seal the inside of the pipe.

[0105] The fixing device includes a fixing frame 800, a clamping mechanism 810 mounted on the fixing frame 800 for clamping the pipe material, and a probe for detecting the plug inside the straight pipe on the pipe material. The clamping mechanism 810 is used to clamp the pipe material and keep it stationary. In this way, during the plugging process, the pipe material will not change position under the action of external force, which would increase the difficulty of plugging. After one end of the pipe material is plugged, the pipe material is detected by the probe. If the plugging is successful, the pipe material is transferred to another fixing device to continue plugging. If the plugging is unsuccessful, the pipe material can be screened out and prevented from being sent to the fixing device, thereby ensuring the processing efficiency of the pipe material.

[0106] The pipe plug device 60 includes a device body 600, on which a four-axis robot 610 and a pusher arm 620 located below the four-axis robot 610 are provided. The device body 600 is provided with a storage component, which includes a material bucket 630 and a vibrating plate 631 located below the material bucket 630. The straight pipe plug is stored in the material bucket 630 and is conveyed to the vibrating plate 631 by the material bucket 630. The four-axis robot 610 includes a mechanical clamping arm 611 for clamping the straight pipe plug on the vibrating plate 631. The pusher arm 620 pushes the straight pipe plug held by the mechanical clamping arm 611 into the end of the pipe.

[0107] The tube plugging device 60 is used to insert the straight tube inner plug into the end of the tube to seal the tube and prevent dust from entering the tube. The straight tube inner plug is placed in the storage assembly. When the plugging operation is performed, the straight tube inner plug falls onto the vibrating plate 631. The vibrating plate 631 vibrates and vibrates the straight tube inner plug until it tilts. The four-axis robot 610 moves the mechanical clamping arm 611 above the vibrating plate 631 to clamp the straight tube inner plug. Then, the four-axis robot 610 drives the mechanical clamping arm 611 to reset so that the straight tube inner plug is facing the center of the tube. Finally, the pusher arm 620 pushes the straight tube inner plug into the end of the tube.

[0108] The four-axis robot 610 includes a robot body 612, and a mechanical gripper 611 connected to the robot body 612 via a telescopic rod 613. The mechanical gripper 611 includes a gripper base 614 and a pair of clamping plates 615 disposed below the gripper base 614. The mechanical gripper 611 clamps the straight tube plug between the clamping plates 615. Under the action of the telescopic rod 613, the vertical position of the mechanical gripper 611 can be adjusted to lower it onto the vibrating plate 631 to clamp the straight tube plug. At the same time, the position of the mechanical gripper 611 can also be adjusted according to the tube specifications to ensure that the straight tube plug is aligned with the tube axis, avoiding misalignment during the plugging process, which could lead to damage to the straight tube plug or plugging failure.

[0109] The pusher arm 620 includes a mounting base 621 on the device body 600 and a pusher cylinder 622 on the mounting base 621. A pusher plate 623 is provided at the end of the pusher cylinder 622, and the pusher plate 623 is positioned at the center between two clamping plates 615. The pusher cylinder 622 can drive the pusher plate 623 to move, pushing the straight pipe plug held by the clamping plates 615 towards the pipe material, causing the straight pipe plug to be inserted into the pipe material. The pusher plate 623 can cover a large area, and even when handling pipe materials of different sizes, the straight pipe plug can be pushed in smoothly.

[0110] The device body 600 is equipped with a vision probe 601 corresponding to the vibrating plate 631, which is used to detect the overturned straight tube plugs on the vibrating plate 631. The vision probe 601 can identify the state of the straight tube plugs on the vibrating plate 631, so that the mechanical clamping arm 611 can clamp the overturned straight tube plugs to smoothly perform the plug cap operation.

[0111] The material storage assembly also includes a conveyor 631 located above the material bin 630. The upper part of the material bin 630 is open to correspond to the conveyor 631, and the lower part of the material bin 630 is open to correspond to the vibrating disc 631. The bottom wall of the material bin 630 is inclined towards the vibrating disc 631. The number of straight tube plugs stored in the material bin 630 is limited. The conveyor 631 can feed the straight tube plugs into the material bin 630 from the upper open part of the material bin 630, and then feed them onto the vibrating disc 631 through the lower open part of the material bin 630.

[0112] A limiting baffle 632 is provided on the circumference of the vibrating plate 631. The vibration generated by the vibrating plate 631 can cause the straight tube inner plug to vibrate and move on the vibrating plate 631. By setting the limiting baffle 632, the straight tube inner plug can be limited to the vibrating plate 631 to prevent the straight tube inner plug from falling off the vibrating plate 631.

[0113] The radial tube transfer device 50 includes a transverse conveyor frame 500 and a material-pushing rod 510 disposed on the transverse conveyor frame 500. The transverse conveyor frame 500 is provided with a power device 520 for driving the material-pushing rod 510. The power device 520 includes a third power motor 521 and a transmission device that is driven by the third power motor 521. The transmission device is connected to the material-pushing rod 510 through a connecting block 522. One end of the connecting block 522 is connected to the transmission device, and the other end is rotatably connected to the material-pushing rod 510. The transmission device drives the connecting block 522 to rotate. The transverse conveyor frame 500 is also provided with a circular slider 530. The material-pushing rod 510 is provided with a guide groove 531 that slides with the circular slider 530.

[0114] When the tube material is moved laterally, the third power motor 521 starts and transmits power to the transmission device. The transmission device drives the connecting block 522 to rotate. During the rotation of the connecting block 522, it pushes the material-pushing rod 510 to move towards the tube material. At the same time, the connecting block 522 also drives the material-pushing rod 510 to move downward so that the material-pushing rod 510 moves below the tube material. The circular slider 530 slides in the guide groove 531 to position the material-pushing rod 510 and prevent the material-pushing rod 510 from rotating relative to the connecting block 522 on its own, which would affect the transmission of the tube material. As the connecting block 522 continues to rotate, it drives the material-pushing rod 510 to reset. When the material-pushing rod 510 resets, it drives the tube material to move upward, so that the tube material falls onto the material-pushing rod 510 and moves along the surface of the material-pushing rod 510, realizing the radial transmission of the tube material.

[0115] The material-feeding rod 510 includes a material-feeding rod body 511, with a material-feeding hook 512 at one end. When the material-feeding rod 510 resets from below the tube, the material-feeding hook 512 positions the tube on the material-feeding rod body 511. The material-feeding hook 512 protrudes from the material-feeding rod body 511. As the material-feeding rod 510 moves upward, it can move the tube along with it to transfer the tube. The tube on the material-feeding rod body 511 is held on the material-feeding rod body 511 by the limiting action of the material-feeding hook 512. When the material-feeding rod 510 resets, the end of the material-feeding rod 510 with the material-feeding hook 512 is higher than the other end, allowing the tube to slide down from the other end of the material-feeding rod 510, completing the lateral transfer of the tube.

[0116] The transmission device includes a transmission support 523 and a pulley 524 rotatably mounted on the transmission support 523. A third power motor 521 is connected to the pulley 524 via a third transmission belt 525. The pulley 524 is connected to a connecting block 522 via a transmission rod. After the third power motor 521 starts, it drives the pulley 524 to rotate via the third transmission belt 525. When the pulley 524 rotates, it drives the connecting block 522 to rotate via the transmission rod, thereby driving the material feeding rod 510 to move.

[0117] Multiple material-pushing rods 510 are arranged along the length of the tube on the transverse conveyor frame 500. A connecting rod 540 passes through these multiple material-pushing rods 510. The connecting rod 540 connects multiple material-pushing rods 510 simultaneously. This means that only one material-pushing rod 510 needs to be connected to the transmission device to achieve synchronous movement of all material-pushing rods 510. This ensures smooth movement of the tube, prevents positional deviation, and facilitates smooth transverse transfer of the tube.

[0118] To maintain the stability of the tube and reduce its positional deviation, a silicone friction element 513 is provided on the upper surface of the feeding rod 511. The silicone friction element 513 has a large coefficient of friction with the tube, and the tube can be axially positioned during the conveying process through the frictional force between it and the silicone friction element 513.

[0119] The clamping device 810 includes a clamping bracket 811. The upper end of the clamping bracket 811 is provided with a V-shaped groove 812. The side of the clamping bracket 811 is provided with a clamping cylinder 813. The clamping cylinder 813 is connected to a V-shaped block 814 that is adapted to the V-shaped groove 812. The feeding rod 510 drives the tube material to rise along the surface of the V-shaped block 814 and pass over the V-shaped block 814. The V-shaped groove 812 has a positioning function for the tube material. When the tube material is conveyed to the clamping bracket 811, it can naturally roll along the inner wall of the V-shaped groove 812 to the center of the V-shaped groove 812 to correspond to the mechanical clamping arm 611. The clamping cylinder 813 drives the V-shaped clamping block 814 to descend to clamp the tube material. After the tube material is capped, the feeding rod 510 drives the tube material to move upward. After the tube material contacts the V-shaped clamping block 814, it can move along the inclined surface on the outside of the V-shaped clamping block 814 and pass over the V-shaped clamping block 814, moving in the radial direction.

[0120] After the capping is completed, the radial tube transfer device 50 conveys the tube material to the automatic packaging mechanism 70 for packaging. The automatic packaging mechanism 70 includes a strapping machine 700, a pusher 710 located behind the strapping machine 700, the radial tube transfer device 50 located on the side of the strapping machine 700, and a laminating machine 720 located in front of the strapping machine 700. The radial tube transfer device 50 conveys the tube material laterally to the strapping machine 700. The strapping machine 700 includes a strapping frame 701, a clamping port 730 located on the strapping frame 701, and a drive roller 720 rotatably mounted on the strapping frame 701. 02 and a bundling unit 703, the tube is supported on the transmission roller 702, the clamping port 730 includes a fixed clamping end 731 and a movable clamping end 732, the movable clamping end 732 moves toward the fixed clamping end 731 to clamp the tube, the pusher 710 is used to push the tube toward the laminating machine 720, including a pusher frame 711 and a sliding mechanism 712 on the pusher frame 711, the sliding mechanism 712 is provided with a top pusher plate 713.

[0121] The automatic packaging mechanism 70 is used for automatic packaging of pipe materials. The strapping machine 700 can perform strapping on the pipe materials, and the laminating machine 720 can package the strapped pipe materials. The pipe materials are laterally conveyed to the strapping machine frame 701 by the radial pipe material transfer device 50. The pipe materials are placed on the transmission rollers 702 on the strapping machine frame 701. When the number of pipe materials reaches a certain requirement, the sliding mechanism 712 moves towards the laminating machine 720 to push the pipe materials through the top material push plate 713, so that the ends of the pipe materials are aligned. The clamping movable end 732 moves towards the clamping fixed end 731 to clamp the pipe materials, so that multiple pipe materials are stacked. The strapping machine 700 straps the stacked pipe materials, and the sliding mechanism 712 continues to push the strapped pipe materials, so that the pipe materials enter the laminating machine 720 for packaging. During the movement of the pipe materials, the conveying rollers keep rotating synchronously to reduce wear on the pipe materials and the strapping tape.

[0122] The clamping movable end 732 and the clamping fixed end 731 have the same structure, including a clamping push plate 734. The clamping push plate 734 is provided with guide ribs 735, which include vertical ribs 736 and arc-shaped ribs 737 connected to each other from top to bottom. The clamping push plate 734 can radially limit the tube material to prevent it from falling off the strapping frame 701 from the side of the clamping port 730 when clamping. The clamping ribs have a guiding effect on the tube material. The arc-shaped rib 737 located below can guide the tube material to move upward along the surface of the arc-shaped rib 737 as the clamping movable end 732 and the clamping fixed end 731 gradually approach each other, making it easier to stack multiple tube materials.

[0123] The clamping port 730 also includes a clamping motor 704 and a clamping base 705. The clamping base 705 is provided with a third limiting slide rail 706. The clamping movable end 732 includes a movable base 738 that slides with the third limiting slide rail 706. The clamping motor 704 is threadedly engaged with the movable base 738 via a clamping screw 707. The clamping motor 704 can drive the clamping screw 707 to rotate. Through the threaded engagement with the movable base 738, it can drive the clamping movable end 732 to move along the third limiting slide rail 706. Under the combined action of the third limiting slide rail 706 and the movable base 738, the displacement of the clamping movable end 732 in the axial direction and the circumferential movement of the pipe are restricted, so as to ensure that the clamping movable end 732 only moves in the radial direction of the pipe.

[0124] The sliding mechanism 712 includes a fixed track 714 and multiple fixed bases 715 fixedly mounted on the fixed track 714. Fixed slides 716 are provided on the fixed bases 715, and sliding members 717 are slidably mounted on the fixed slides 716. A top-push plate 713 is mounted on the end of the sliding member 717. The sliding member 717 can slide on the fixed slides 716, driving the top-push plate 713 to move synchronously, thereby pushing the pipe material.

[0125] A drive frame 718 is fixedly mounted on the pusher frame 711 near the strapping machine 700. The drive frame 718 is equipped with a motor and a gear 719 driven by the motor. The gear 719 meshes with a sliding member 717. Driven by the motor, the gear 719 rotates, and through its meshing with the sliding member 717, it drives the sliding member 717 to move. The position control of the sliding member 717 is relatively precise. Simultaneously, the cooperation between the sliding member 717 and the gear 719 restricts the vertical displacement of the sliding member 717, preventing positional deviation.

[0126] The strapping frame 701 and strapping unit 703 are arranged at intervals along the axial direction of the pipe. During the strapping of the pipe, the pipe is clamped through multiple clamping ports 730, which allows the pipe to be stacked better and the strapping effect to be better. Strapping is performed at multiple points along the axial direction of the pipe to keep the pipe in a stacked state and prevent it from scattering. The packaged pipe can be stacked neatly for easy transportation.

Those skilled in the art should understand that the present invention includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of the present invention will be included within the scope of the claims.
