Description

[Technical Field]

[0001] This invention relates to the field of pipe processing equipment, and more particularly to an automatic feeding device and a pipe packaging device. [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.

[0003] To reduce manpower input, a set of equipment that can automate the pipe material processing is needed. [Summary of the Invention]

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art by proposing an automatic feeding device that can sort the pipes so as to realize the individual conveying of the pipes and facilitate the processing of the pipes.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] An automatic feeding device includes a base, on which a storage rack, a first distributing frame, and a second distributing frame are mounted. A rack lift connected to the storage rack is mounted on the base. The rack lift drives the storage rack upwards to transfer the tubular material on the storage rack to the first distributing frame. A pusher is provided between the first and second distributing frames to feed the tubular material from the first distributing frame into the second distributing frame. A chain plate assembly is provided on the side of the second distributing frame to convey the tubular material one by one. A conveyor belt assembly is provided between the second distributing frame and the chain plate assembly. The conveyor belt assembly feeds the tubes one by one onto the chain plate assembly. The pusher includes a pusher support and a pusher lever disposed on the pusher support. The pusher lever includes a blocking member and a guide member connected to each other. The guide member has an inclined surface arranged from the first distribution frame toward the second distribution frame so that the lifted tubes roll off the guide member onto the second distribution frame. The blocking member stops the tubes on the first distribution frame from moving below the guide member when the guide member lifts the tubes. The pusher support is provided with a changing cylinder that drives the pusher lever to move toward the first distribution frame or the second distribution frame.

[0007] 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.

[0008] Based on the above scheme, the base is provided with an upper detection sensor and a lower detection sensor to detect the quantity of pipes on the first material distribution frame. In the vertical plane, the upper detection sensor is located at the end of the first guide surface near the first blocking surface, and the lower detection sensor is located at the end of the first guide surface near the second material distribution frame.

[0009] Based on the above scheme, multiple first material distribution frames and multiple second material distribution frames are arranged at intervals along the length direction of the base. The multiple first material distribution frames and multiple second material distribution frames are arranged in a one-to-one correspondence. A first gap is formed between two adjacent first material distribution frames, and a second gap is formed between two adjacent second material distribution frames that communicates with the first gap. The pusher is located in the first gap and the second gap.

[0010] Based on the above scheme, the automatic feeding device also includes an anti-stacking mechanism. The anti-stacking mechanism includes anti-stacking bases disposed on both sides of the conveyor belt assembly and a blocking member disposed above the conveyor belt assembly. The anti-stacking base is provided with a screw assembly that connects to the blocking member. The screw assembly adjusts the distance between the blocking member and the conveyor belt assembly according to the pipe specifications.

[0011] Based on the above scheme, the storage rack includes a storage frame, the storage frame includes a bottom baffle, the bottom baffle is connected to a side baffle at the end away from the first material distribution frame, and 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.

[0012] Based on the above scheme, the material rack lifting machine is located below the bottom baffle, and multiple sets of material rack lifting machines are arranged at intervals along the length of the storage rack, with each set of material rack lifting machines including at least two material rack lifting machines.

[0013] Based on the above solution, the base is provided with a guide rail 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.

[0014] 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.

[0015] The tube packaging device includes the aforementioned automatic feeding device.

[0016] The beneficial effects of this invention are:

[0017] This invention discloses an automatic feeding device capable of automatically feeding pipe materials. In the initial stage of equipment operation, pipe materials are stacked in a storage rack. The storage rack is lifted by a hoist, and after rising a certain distance, a portion of the pipe materials stacked on the rack enters the first sorting rack, achieving the first sorting. A pusher then feeds a portion of the pipe materials from the first sorting rack to the second sorting rack, achieving the second sorting. A conveyor belt assembly transports the pipe materials from the second sorting rack to the chain plate assembly. The conveyor belt assembly allows the pipe materials to be transported to the chain plate assembly at a uniform speed, achieving pipe-by-pipe transport. In this way, the pipe materials can be transported one by one by the chain plate assembly. Through two sorting processes, the large pile of pipe materials is divided into smaller portions for transport, avoiding the stacking phenomenon during pipe transport and preventing disruption to the automated pipe transport process.

[0018] 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.

[0019] The changing cylinder can drive the pusher lever to adjust the position of the pusher lever relative to the first and second material distribution frames, thereby changing the projected area of ​​the tube on the guide member located on the first material distribution frame. This increases or decreases the effective length of the tube lifted by the guide member. To ensure better operation of the conveyor belt assembly, the number of tubes conveyed each time needs to be fixed. When the tube size is different, the number of tubes that the guide member of the same length can lift is different. The position of the pusher lever is adjusted according to the size of the tube, thereby fixing the number of tubes lifted by the pusher member each time.

[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 base is equipped with an upper detection sensor and a lower detection sensor to detect the quantity of pipes on the first dispensing frame. In the vertical plane, the upper detection sensor is located at the end of the first guide surface near the first blocking surface, and the lower detection sensor is located at the end of the first guide surface near the second dispensing frame. The upper and lower detection sensors can respectively detect whether there are pipes on the end of the first guide surface near the first blocking surface and the end near the second dispensing frame, thereby determining whether the quantity of pipes on the first dispensing frame is sufficient. When the upper detection sensor detects the presence of pipes, it means that there are sufficient pipes on the first dispensing frame, and the material rack lift does not need to drive the storage rack to transfer pipes, thus avoiding the accumulation of pipes on the first dispensing frame. When the lower detection sensor does not detect the presence of pipes, it means that there are insufficient pipes on the first dispensing frame, and the material rack lift needs to be started in time to replenish pipes on the first dispensing frame.

[0022] Furthermore, the automatic feeding device also includes an anti-stacking mechanism. This mechanism includes anti-stacking bases on both sides of the conveyor belt assembly and a blocking member above the conveyor belt assembly. The anti-stacking bases are equipped with a screw assembly connecting the blocking member. The screw assembly adjusts the distance between the blocking member and the conveyor belt assembly according to the pipe specifications. The anti-stacking mechanism prevents pipe stacking on the conveyor belt assembly. As the conveyor belt moves, the pipes gradually approach the chain plate assembly. When the pipes pass the blocking member, they pass underneath it. If stacking occurs, the uppermost pipes are blocked by the blocking member, preventing them from maintaining their stacked state. The screw assembly can adjust the height of the blocking member according to the pipe specifications, maintaining a suitable distance between the blocking member and the conveyor belt assembly.

[0023] Furthermore, the storage rack includes a storage frame, which includes a bottom baffle. The bottom baffle, located away from the first distributing frame, is connected to a side baffle. The bottom baffle has a support beam for supporting the pipe material, and the height of the support beam gradually decreases from the side baffle towards the first distributing frame. The storage frame can be used to hold the pipe material, and the side baffle is used to limit the pipe material to prevent it from falling off the side of the storage frame to the base. The side of the storage frame facing the first distributing frame does not have a limiting mechanism for the pipe material. Thus, as the storage rack is lifted upwards, the pipe material can move towards the first distributing frame under its own weight and the guidance of the support beam. After a portion of the pipe material is transferred to the first distributing frame, the rack lift drives the storage rack downwards to stop the transfer of pipe material towards the first distributing frame.

[0024] Furthermore, the material rack lifting mechanism is located below the bottom baffle, and multiple sets of material rack lifting mechanisms are spaced apart along the length of the storage rack. Each set of material rack lifting mechanisms includes at least two lifting mechanisms. By setting multiple sets of material rack lifting mechanisms, the storage rack 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, which would affect the conveying process of the pipe and reduce collisions during the conveying process. Each set of material rack lifting mechanisms includes at least two lifting mechanisms, which can ensure the stability of the storage rack, reduce the tilting of the storage rack, and ensure that the pipe can be conveyed smoothly.

[0025] Furthermore, the base is provided with a guide rail 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 cooperation between the guide rail and the guide slider makes the lifting and lowering process of the storage rack smoother, reducing any jerking sensation during the lifting and lowering process.

[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 uses the above-mentioned automatic feeding device to feed tubes, so as to realize the transmission of single tubes and facilitate the tube packaging device to perform various processing operations on the tubes.

Detailed Implementation Methods

[0047] 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.

[0048] 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.

[0049] Reference Figures 1 to 7This invention discloses an automatic feeding device, including a base 100. The base 100 is provided with a storage rack 110, a first distributing frame 120 and a second distributing frame 130. A pusher 140 is provided between the first distributing frame 120 and the second distributing frame 130 for feeding 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. The base 100 is provided with a rack lift 111 connected to the storage rack 110. 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.

[0050] The automatic feeding device disclosed in this invention can realize the automatic feeding of pipe materials. In the initial stage of equipment operation, the pipe materials are piled up in the storage rack 110. The storage rack 110 is driven to move up and down by the rack lift 111. After the storage rack 110 rises a certain distance, part of the pipe materials piled on the storage rack 110 can enter the first sorting frame 120 to realize the first sorting. The pusher 140 sends part of the pipe materials on the first sorting frame 120 to the second sorting frame 130 to realize the second sorting. The pipe materials located on the second sorting frame 130 can roll towards the chain plate assembly 150 under the action of gravity, so that they can be conveyed one by one by the chain plate assembly 150. Through two sorting, the large pile of pipe materials is divided into small parts for conveying, which can avoid the phenomenon of stacking during pipe material conveying and thus avoid affecting the automatic transmission of pipe materials.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] Reference Figure 8 The present invention also discloses a tube packaging device, which uses the aforementioned automatic feeding device to feed tubes, thereby realizing the conveying of single tubes and facilitating various processing operations on the tubes. By setting up multi-level material distribution, a large pile of tubes is gradually divided into several single tubes for transportation, effectively avoiding the stacking of tubes and the resulting impact on the packaging process.

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.

A chain plate assembly is located on the side of the second distributing frame to convey the tubular material one by one. A conveyor belt assembly is located between the second distributing frame and the chain plate assembly. The conveyor belt feeds the tubes one by one onto the chain plate assembly. The pusher includes a pusher support and a pusher lever on the pusher support. The pusher lever includes a blocking member and a guide member connected to each other. The guide member has an inclined surface from the first distribution frame toward the second distribution frame so that the lifted tubes roll off the guide member onto the second distribution frame. The blocking member stops the tubes on the first distribution frame from moving below the guide member when the guide member lifts the tubes. The pusher support is provided with a changing cylinder that drives the pusher lever to move toward the first distribution frame or the second distribution frame. The first dispensing frame is provided with a first blocking surface facing the storage rack and a first guide surface inclined towards the second dispensing frame. The first blocking surface blocks and limits the pipe material on the storage rack. The second dispensing frame includes a second blocking surface facing the first dispensing frame and a second guide surface facing the chain plate assembly. The second blocking surface blocks and limits the pipe material on the first dispensing frame. The pusher lifts the pipe material in the first dispensing frame upward until it passes the second guide surface. The pusher feeds part of the pipe material on the first dispensing frame into the second dispensing frame to achieve a second dispensing. A plurality of first dispensing frames and a plurality of second dispensing frames are spaced apart along the length direction of the base. The plurality of first dispensing frames and the plurality of second dispensing frames are arranged one-to-one. A first gap is formed between two adjacent first dispensing frames, and a second gap communicating with the first gap is formed between two adjacent second dispensing frames. The pusher is disposed in the first gap and the second gap. The base is equipped with an upper detection sensor and a lower detection sensor to detect the quantity of pipe material on the first material distribution frame. In the vertical plane, the upper detection sensor is located at one end of the first guide surface near the first blocking surface, and the lower detection sensor is located at one end of the first guide surface near the second material distribution frame. The automatic feeding device also includes an anti-stacking mechanism, which includes anti-stacking bases on both sides of the conveyor belt assembly and a blocking member above the conveyor belt assembly. The anti-stacking bases are provided with a screw assembly that connects to the blocking member.
