[0009] 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.

[0010] 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.

[0011] Based on the above scheme, the guide plate is set at the center of the corresponding roller, the conveying roller is a straight cylindrical roller, and the conveyor frame is provided with a pipe diameter changing clamping mechanism for adjusting the distance between the guide plates. The pipe diameter changing clamping mechanism includes a driver and a limiting slide rail set on the guide base.

The driver drives the sliding seat to slide along the limiting slide rail to adjust the position of the guide plate.

[0012] Based on the above scheme, the pipe diameter changing clamping mechanism further includes a pair of connecting rods. The connecting rods are arranged along the length of the conveyor frame and connected to at least two sliding seats. The driver connects to the connecting rods to drive the connecting rods to move along the width of the conveyor frame.

[0013] 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.

[0014] Based on the above scheme, a conveyor belt assembly is also provided between the second material distribution frame and the chain plate assembly, and the conveyor belt assembly feeds the pipes one by one onto the chain plate assembly.

[0015] Based on the above scheme, the chain plate assembly includes a chain plate frame, a chain set on the chain plate frame, and a chain plate driver for driving the chain transmission. The chain is provided with multiple conveyor plates, and a conveying area for carrying pipe materials is formed between two connected conveyor plates.

[0016] The tube packaging device includes the aforementioned automated grading and feeding device.

[0017] The beneficial effects of this invention are:

[0018] This invention discloses an automated grading and feeding device. The grading and feeding device transfers pipes one by one to a pipe conveying device, which then transports the pipes. In the initial stage of equipment operation, the pipes are piled up in a storage rack. The storage rack is driven to move up and down by a rack lift. After the storage rack rises a certain distance, some of the pipes piled on the storage rack can enter the first sorting rack, achieving the first sorting. A pusher then feeds some of the pipes on the first sorting rack into the second sorting rack, achieving the second sorting. The pipes on the second sorting rack can roll towards the chain plate assembly under the action of gravity, thus being transported one by one by the chain plate assembly. When the pipes are transported to the end of the chain plate assembly, they fall downwards and fall into the pipe conveying device through the conveying gap between two guide plates. By sorting the pipes twice, the large pile of pipes is divided into smaller portions for transport, which can avoid the stacking phenomenon during pipe transport and the resulting impact on the automated transport of pipes. During the conveying process on the pipe conveyor, the pipe material is placed on the conveyor rollers. The conveyor rollers can rotate relative to the roller mounting base to reduce the friction between the pipe material and the rollers. The pipe conveyor is used in pipe processing equipment as a device for conveying pipe material between two pipe processing machines. To reduce radial displacement of the pipe material, a guide mechanism is installed on the side of the roller mounting base to guide the pipe material into the conveyor frame, making the pipe material conveying more stable. When feeding material onto the pipe conveyor, two graded feeding devices feed material alternately, which can double the pipe material conveying efficiency of the pipe conveyor, thus improving the pipe material processing efficiency.

[0019] Furthermore, the storage rack includes a storage frame, the storage frame includes a bottom baffle, the bottom baffle is connected to a side baffle at one end away from the first material distribution frame, the bottom baffle is provided with a support beam for supporting the pipe material, the height of the support beam gradually decreases from the side baffle toward the first material distribution frame, the base is provided with a guide rail located on the side of the side baffle, and the storage rack is provided with a guide slider that slides in cooperation with the guide rail. The storage frame can be used to hold pipes, and the side baffles are used to limit the pipes to prevent them from falling off the base from the side of the storage frame. The side of the storage frame facing the first distribution frame does not have a limiting mechanism for the pipes. In this way, as the storage frame is lifted upward, the pipes can move towards the first distribution frame under their own weight and the guidance of the support beam. After part of the pipes are transferred to the first distribution frame, the material rack elevator drives the storage frame to move downward to stop the transfer of pipes towards the first distribution frame. Through the cooperation of the guide rail and the guide slider, the lifting process of the storage frame is made smoother and the jerking sensation during the lifting process is reduced.

[0020] 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.

[0021] 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.

[0022] Furthermore, the guide plate is positioned at the center of the corresponding roller, and the conveying roller is a straight cylindrical roller. The conveyor frame is equipped with a pipe diameter changing clamping mechanism for adjusting the distance between the guide plates. The pipe diameter changing clamping mechanism includes a driver and a limiting slide rail disposed on the guide base. The guide plate includes a sliding seat, which is slidably mounted on the limiting slide rail. The driver drives the sliding seat to slide along the limiting slide rail to adjust the position of the guide plate. Since the size specifications of the pipe are not fixed, the conveying roller is set to be cylindrical to accommodate various specifications of pipe. However, this means that the conveying roller does not have a guiding function or radial limiting function for the pipe. To accommodate different pipes, the distance between the two guide plates can be adjusted by the pipe diameter changing clamping mechanism. This provides better guiding for various specifications of pipe. The sliding seat is slidably mounted on the limiting slide rail to limit the guide plate in the length direction of the conveyor frame. The pipe diameter changing clamping mechanism can adjust the position of the guide plate on the limiting slide rail, thus allowing the distance between the guide plates to be adjusted according to the pipe specifications.

[0023] Furthermore, the pipe diameter changing clamping mechanism also includes paired connecting rods. These connecting rods are arranged along the length of the conveyor frame and connect to at least two sliding seats. The driver connects to the connecting rods to drive them to move along the width of the conveyor frame. The connecting rods can simultaneously connect to multiple sliding seats. When the position of the connecting rods changes in the width 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 rods, when the driver is stationary, the position of the guide plates will also remain stationary along with the connecting rods, thus preventing changes in the spacing between the guide plates during pipe conveying.

[0024] Furthermore, the driver includes a motor, a lead screw driven by the motor, and nuts threaded onto 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.

[0025] Furthermore, a conveyor belt assembly is provided between the second material sorting frame and the chain plate assembly. The conveyor belt assembly delivers the pipes one by one to the chain plate assembly. The conveyor belt assembly is used to send the pipes conveyed to the second material sorting frame to the chain plate assembly. The conveyor belt assembly can make the pipes be conveyed to the chain plate assembly at a uniform speed, realizing the one-by-one transport of the pipes.

[0026] Furthermore, the chain plate assembly includes a chain plate frame, a chain mounted on the chain plate frame, and a chain plate driver for driving the chain transmission. The chain has multiple conveyor plates, with a conveying area for carrying the pipe material formed between two connected conveyor plates. The chain plate driver provides power for the chain transmission. During chain transmission, the pipe material falls into the conveying area between two connected conveyor plates, and the pipe material can move along with the chain transmission.

[0027] The present invention also discloses a tube packaging device, which adopts the above-mentioned automated graded feeding device to realize the transmission of single tubes, facilitate the conveying and processing of tubes, and automate the entire process, reducing manpower input.

[0028] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and accompanying drawings. [Attached Image Description]

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.

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.

[0045] Reference Figures 1 to 10 This invention discloses an automated grading and feeding device for use in tube packaging equipment. It includes a grading and feeding device and a tube conveying device. The grading and feeding device is used to grade and convey tubes, gradually dividing a large pile of tubes into small piles, several tubes, and single tubes. Then, the tubes are fed one by one into the tube conveying device for conveying. In order to improve the conveying efficiency and processing speed of tubes, grading and feeding devices are provided on both sides of the tube conveying device.

[0046] The graded feeding device 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 rack lift 111 connected to the storage rack 110 is provided on the base 100. The 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.

[0047] The graded feeding device enables automatic feeding of pipe materials. In the initial stage of equipment operation, pipe materials are piled in the storage rack 110. The rack is lifted by the rack elevator 111. After the rack rises a certain distance, some of the pipe materials piled 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.

[0048] The pipe conveying device 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.

[0049] After the tube material is conveyed to the end of the chain plate assembly 150 by the grading and feeding device, it falls downwards and through the conveying gap 201 between the two guide plates 221 into the tube material conveying device. The tube material conveying device keeps the tube material stable during the conveying process and 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 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. 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. The 0 is set to a straight cylindrical shape to accommodate pipes of various specifications. However, this means that the conveyor 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 on pipes of various specifications.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] The chain plate assemblies 150 located on both sides of the pipe conveying device are configured to correspond to the conveying gap 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.

[0065] The aforementioned pipe diameter changing clamping mechanism 230 includes a driver 231 and a 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 limiting slide rail 223. The driver 231 drives the sliding seat 224 to slide along the limiting slide rail 223 to adjust the position of the guide plate 221. The sliding seat 224 is slidably mounted on the 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 limiting slide rail 223, thereby allowing the spacing between the guide plates 221 to be adjusted according to the pipe specifications.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] The conveyor frame 200 is also equipped with a power motor 212. The ends of two adjacent conveyor rollers 210 are connected by a conveyor belt 213. The conveyor rollers 210 located at the ends are connected to the power motor 212 by the conveyor belt 213. The power motor 212 can drive the conveyor belt 213 to drive the conveyor rollers 210 located at the ends to rotate. Power is transmitted between the conveyor rollers 210 through the conveyor belt 213, so that all the conveyor rollers 210 can rotate to convey the pipe material.

[0070] Reference Figure 10 The present invention also discloses a tube packaging device, which uses the above-mentioned automated graded feeding device to perform tube feeding and conveying operations, so as to realize the conveying of single tubes, so as to facilitate the tube packaging device to perform various processing operations on the tubes. By setting up multi-level material division, a large pile of tubes is gradually divided into several single tubes for transportation, effectively avoiding the stacking of tubes and affecting the tube packaging process. The tube conveying process can remain stable, and when processing tubes of different specifications, the tube conveying device can also be adjusted according to the specifications of the tubes, improving the adaptability of the equipment.

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.
