[0020] As a preferred embodiment of the intelligent raw material conveying production line of the present invention, wherein: both ends of the horizontal roller are vertically welded with a turning plate, and the lower end of the turning plate includes an elastic steel fork.

[0021] This invention provides an intelligent raw material conveying production line with the following significant improvements and advantages compared to the prior art:

[0022] The intermittent motion roller rotates 120° intermittently, causing the unloading roller trough, which is filled with stem raw materials at the bottom of the storage tank, to move to the unloading port area. The stem raw materials are released and fall into the right inclined area, where they are caught by the hook set that is passing by. The hooks then move the stem raw materials to the upper plane area. The hooks pass through the openings in the partition, thus preventing raw materials from remaining in the unloading roller trough. When the stem raw materials that are partially wrapped around the hooks move from the upper plane area to the left inclined area, they pass through several sets of unhooking frames. The stem raw materials are intercepted and unhooked by the unhooking frames and then fall onto the conveyor belt. This significantly improves the grabbing and transportation efficiency of stem raw materials and avoids material leakage.

[0023] The second servo motor is started, which drives the intermittent rotation of the moving blade holder through transmission. This causes the polyurethane scraper blade carrying the dirt to move downwards, while another set of polyurethane scraper blades moves upwards to contact the bottom of the conveyor belt, achieving the purpose of automatically replacing the polyurethane scraper blades. This achieves a high degree of automation. At the same time, with the power of the second servo motor, the camshaft is accelerated through the sprocket structure, causing the two sets of rotating cams to rotate. When the protrusion of the rotating cam moves to the position of the corresponding guide pulley, it generates an upward squeezing force, causing the corresponding telescopic rod to move upwards. This drives the self-correcting wheels in the two sets of forks to approach the moving chain, and partially extend into both sides of the chain. Through the rolling force, the misaligned chain is squeezed, achieving the effect of fine adjustment and correction. The chain needs to be maintained regularly.

[0024] The screw motor is started, driving the screw to rotate, which causes the wiping fixture to move linearly within the auxiliary base. On one hand, this allows the downward-facing polyurethane scraper to enter between two sets of limiting guide plates. The limiting guide plates limit the polyurethane scraper, keeping the entire moving blade holder stable and stationary, improving the shock absorption effect during scraping. On the other hand, the scraper's arc head extends into the concave surface of several sets of wiping rollers, contacting the wiping cotton layer. Through relative contact force, the wiping rollers rotate autonomously, wiping away the dirt on the scraper's arc head, avoiding cross-contamination, and also cooling the scraper's arc head, achieving automatic cleaning and cooling. This saves time and effort, extends the service life of the polyurethane scraper, and demonstrates a high degree of automation and intelligence.

[0025] The drive motor is started, and the drive shaft drives the crank to make a circular motion. Through a series of transmissions, the suction tube swings synchronously, so that the lower end of the suction tube moves a wide range in the lower part of the material bin of the machine. Meanwhile, several sets of scrapers on the suction tube opening automatically scrape away small raw materials that are obstructing the movement of the tube, and prevent the tube opening from being blocked, thereby increasing the suction range of the pneumatic suction pipe. With the power of the drive shaft, the two sets of turning blades on the horizontal roller shaft make a circular motion through the belt drive. During the movement, the two sets of turning blades turn up the small raw materials accumulated around them and randomly throw them from the outside to the inside into the movement path of the suction tube opening, ensuring that the suction tube has a sufficient and stable supply of small raw materials for pneumatic suction, which significantly improves the suction effect.

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0045] like Figures 1-12 As shown, this embodiment provides an intelligent raw material conveying production line, including a conveying main support 1. The conveying main support 1 is located at the right end of the connecting seat 20. A three-sided conveyor 2 is installed inside the conveying main support 1. The three-sided conveyor 2 consists of multiple sets of transmission sprockets and motors. The three-sided conveyor 2 includes an upper plane area, a left inclined plane area, and a right inclined plane area. The upper plane area, the left inclined plane area, and the right inclined plane area are all connected by chains 3. Several sets of material receiving hook groups 4 are evenly distributed on the chains 3. Each set of hook groups 4 consists of several sets of hooks arranged at equal intervals. The specific shape of the hooks is designed according to the actual situation.

[0046] A cleaning fan 8 is installed at the upper end of the main conveyor support 1, above the upper plane area. The cleaning fan 8 uses a cleaning duct 9 to remove impurities from the raw materials on the hook assembly 4. The airflow direction of the cleaning duct 9 is directly facing the front of the hooks to prevent stem materials from being blown away. Figures 1-3 As shown.

[0047] Furthermore, a material hopper 10 is mounted on the right end of the main conveyor support 1, located on the right inclined area. A storage trough 11 is formed downwards within the material hopper 10. A discharge port 12, connected to the storage trough 11, is formed near the right inclined area of ​​the material hopper 10. An intermittently moving roller 13 is rotatably mounted within the discharge port 12. Figure 3 and Figure 5 As shown.

[0048] Specifically, the two ends of the intermittent motion roller 13 are symmetrically welded with first short shafts 14. The two sets of first short shafts 14 are connected to the inner wall of the discharge port 12 through the first bearing seat 15. One end of the first short shaft 14 extends outward and is connected to a first servo motor 16 through a coupling. The first servo motor 16 horizontally penetrates the outer side of the material hopper 10, such as... Figure 5 and Figure 6 As shown.

[0049] In this embodiment, three sets of partitions 17 are evenly installed on the roller surface of the intermittent motion roller 13, and a discharge roller groove 18 is formed between adjacent partitions 17. When one set of discharge roller grooves 18 moves to the bottom of the storage tank 11, the shape and size of the two fit together, which facilitates the entry of materials. At this time, the other set of discharge roller grooves 18 is located in the discharge port 12 area. Each set of partitions 17 has a through-hole 19 for the hook assembly 4 to pass through, such as Figure 6 As shown.

[0050] Furthermore, a linear conveyor is horizontally installed inside the main conveyor support 1 and on its left side. The linear conveyor includes a conveyor belt 5 that rotates in a circular motion. A support rod 6 is horizontally installed inside the main conveyor support 1 and at the right end of the linear conveyor. Several sets of hook release frames 7, with alternating hooks, are equidistantly fixed to the upper inclined ends of the support rod 6. The hook release frames 7 serve to block and intercept from the front. Figures 1-3 As shown.

[0051] Furthermore, a belt cleaning seat 40 is provided at the lower end of the conveyor main support 1 and below the conveyor belt 5. The belt cleaning seat 40 is riveted to the conveyor main support 1 via a connecting piece 41. A scraping motion chamber 44 is formed inside the belt cleaning seat 40, facing upwards. A collection box 43, which communicates with the scraping motion chamber 44, is connected to the side of the belt cleaning seat 40. A waste trough is formed between adjacent polyurethane scraper blades 51. The waste generated by scraping is guided into the collection box 43 through the waste trough. A dust collection fan can be installed inside the collection box 43. Figure 4 and Figure 7 As shown.

[0052] The scraping motion chamber 44 has a rotating blade holder 50 located in the center. Several sets of polyurethane scraper blades 51 are evenly installed around the outer circumference of the scraper holder 50. Each polyurethane scraper blade 51 includes a scraping arc head 52; the specific shape of the scraping arc head 52 can be designed according to actual conditions. Parts of the polyurethane scraper blades 51 extend outside the scraping motion chamber 44 and act on the conveyor belt 5. Figure 7 and Figure 8 As shown.

[0053] The moving cutter holder 50 has two symmetrically welded second short shafts 53 at both ends. Both sets of second short shafts 53 are connected to the inner wall of the scraper moving chamber 44 through the second bearing seat 54. The end of one set of second short shafts 53 is connected to the second servo motor 55 through a coupling, and the end of the other set of second short shafts 53 extends out of the belt cleaning seat 40 and is fitted with a large sprocket 56. Figure 8 As shown.

[0054] Furthermore, an auxiliary base 42 is connected to the lower end of the belt cleaning seat 40. A lead screw 60 is horizontally installed inside the auxiliary base 42. Both ends of the lead screw 60 are connected to the inner wall of the auxiliary base 42 through lead screw bearings 61. One end of the lead screw 60 extends outward and is connected to a lead screw motor 62 through a coupling. Figures 7-9 As shown.

[0055] The screw 60 is movably mounted with a wiping fixture 63. Inside the wiping fixture 63 is a screw nut sleeve 64 that interacts with the screw 60. Inside the screw nut sleeve 64 is a nut that spirals on the screw 60. Two sets of limiting guide plates 65 acting on the polyurethane scraper 51 are symmetrically fixed to the upper end of the wiping fixture 63. The gap between the two sets of limiting guide plates 65 is just enough for the polyurethane scraper 51 to insert. A cleaning fluid tank 66 is located at the upper part of the interior of the wiping fixture 63. The cleaning fluid tank 66 contains a certain amount of cleaning agent, which needs to be replaced periodically. During the rotation of the moving blade holder 50, the wiping fixture 63 is located at one end of the screw 60 and does not contact the polyurethane scraper 51. Figure 8 and Figure 9 As shown.

[0056] Furthermore, several sets of wipers 70 are installed at equal intervals within the cleaning fluid tank 66, such as... Figure 9 As shown.

[0057] Specifically, the wiper 70 includes a wiping roller 71, a concave arc-shaped wheel surface 72, a wiping cotton layer 73, a wheel axle 74, a vertical bearing seat 75, a perforated connecting platform 76, elastic cleaning filaments 77, and a track 78, such as... Figure 10 As shown.

[0058] In this embodiment, the wiping roller 71 has an arc-shaped concave surface 72 around its circumference for the scraping arc head 52 to extend into, and the two fit together. The arc-shaped concave surface 72 is covered with a wiping cotton layer 73. A portion of the wiping roller 71 is located in the cleaning liquid tank 66. The two ends of the wiping roller 71 are symmetrically provided with axles 74. Each set of axles 74 is equipped with a vertical bearing seat 75, and the rotation between the axle 74 and the vertical bearing seat 75 is smooth.

[0059] In this embodiment, the two sets of vertical bearing seats 75 are connected by a perforated connecting platform 76. The perforated connecting platform 76 is connected to the inner wall of the cleaning liquid tank 66. Several sets of elastic cleaning filaments 77 are evenly distributed at the upper end of the perforated connecting platform 76 near the center. These elastic cleaning filaments 77 have deformation and recovery properties. Through relative movement with the wiping cotton layer 73, they generate contact force to achieve the purpose of cleaning. Tracks 78 that act on the wiping roller 71 are symmetrically installed at the upper end of the perforated connecting platform 76 on both sides of the elastic cleaning filaments 77. These tracks serve as limiting guides and improve the stability of the movement of the wiping roller 71.

[0060] Furthermore, a guide seat 80 is installed at the bottom of the main conveyor support 1 near the left inclined area. A top plate 86 is provided at the upper end of the guide seat 80. A camshaft 81 is horizontally installed at the lower part of the interior of the guide seat 80. Both ends of the camshaft 81 are connected to the inner wall of the guide seat 80 via a third bearing seat 82. Figure 4 , Figure 11 and Figure 12 As shown.

[0061] One end of the camshaft 81 extends outward, passes through the straightening seat 80, and is fitted with a small sprocket 83. The small sprocket 83 and the large sprocket 56 are connected by a synchronous chain 84 for transmission. Two sets of rotating cams 85 are symmetrically fitted on the camshaft 81. Figure 3 , Figure 4 and Figure 11 As shown.

[0062] Each set of rotating cams 85 has a guide pulley 92 mounted on its upper inclined end. The guide pulley 92 is rotatably mounted on a pulley table 91. A telescopic rod 90 is welded to the end of each pulley table 91 away from the guide pulley 92. A limiting rod hole 87 is provided on the top plate 86 for the telescopic rod 90 to pass through, serving as a limiting and guiding function. A return spring 93, sleeved on the outside of the telescopic rod 90, is fixed between the top plate 86 and the pulley table 91. When compressed, the return spring 93 generates a restoring force. Figure 12 As shown.

[0063] In this embodiment, each set of telescopic rods 90 is provided with a fork 94 at its upper end. A self-correcting wheel 95 is rotatably mounted inside the fork 94. The self-correcting wheel 95 is in a standard correction position, and a portion of the self-correcting wheel 95 extends out of the fork 94, acting on the side of the chain 3 to prevent the chain 3 from shifting, causing wear or detachment. Figure 11 and Figure 12 As shown.

[0064] Furthermore, a crusher 21 is provided in the middle of the connecting seat 20. A cleaning mechanism, drying mechanism, etc., can be installed inside the crusher 21. Designed according to actual conditions, the bottom of the crusher 21 is connected to the upper end face of the connecting seat 20 via the machine body hopper 22. The left end of the linear conveyor is located on the crusher 21. A feed inlet 23, which connects to the linear conveyor, is opened near the center of the upper end face of the crusher 21. Figure 1 and Figure 2 As shown.

[0065] Furthermore, a mounting base 24 is provided at the left end of the connecting seat 20, and a suction unit 25 is fixed at the upper end of the mounting base 24. A pneumatic suction pipe 26 is connected to the right end of the suction unit 25, extending downwards into the interior of the machine body's hopper 22. A discharge pipe 27 is connected to the left end of the suction unit 25. Figure 1 and Figure 2 As shown.

[0066] The discharge pipe 27 has a liquid-lifting stirring cylinder 31 connected to its left side. The liquid-lifting stirring cylinder 31 is mounted on a hydraulic mixer 30. The hydraulic mixer 30 also includes an intelligent control console 32, which controls the entire production line's program operation, such as... Figure 1 and Figure 2 As shown.

[0067] In this embodiment, the chain 3 on the three-sided conveyor 2 moves counterclockwise. When the hook group 4 on the chain 3 moves upward in the right inclined area, the first servo motor 16 is started, which drives the intermittent motion roller 13 to rotate intermittently by 120°. This causes the unloading roller trough 18, which is filled with stem raw materials at the bottom of the storage tank 11, to move to the area of ​​the unloading port 12. At the same time, one set of empty unloading roller troughs 18 enters the storage tank 11 to receive materials in turn. The stem raw materials are released quantitatively and fall into the right inclined area, where they are hooked by the hook group 4 that is passing by. The stem raw materials are then moved to the upper plane area, where they are removed by the impurity removal fan 8.

[0068] Subsequently, the stem raw materials fall from the left end of the three-sided conveyor 2 onto the conveyor belt 5 of the linear conveyor. Some of the stem raw materials wrapped around the hooks are intercepted and unhooked by several sets of unhooking frames 7 as they move from the upper plane area to the left inclined plane area. They then fall onto the conveyor belt 5 and, as the conveyor belt 5 moves to the left, enter the crusher 21 through the feed inlet 23 for material crushing. The material is then broken into small pieces and falls into the machine body hopper 22 for temporary storage. By starting the suction unit 25, the small pieces of material in the hopper are pneumatically sucked in through the pneumatic suction pipe 26 and quantitatively introduced into the liquid extraction mixing drum 31 through the discharge pipe 27. They are then mixed with other extraction agents and stirred using the hydraulic mixer 30 or other stirring processes.

[0069] As the conveyor belt 5 moves downwards, it passes over the scraping arc head 52 of the polyurethane scraper blade 51, removing residual dirt from the conveyor belt 5. The second servo motor 55 is periodically activated, and the second short shaft 53 drives the moving blade holder 50 to rotate intermittently. This causes the polyurethane scraper blade 51 carrying the dirt to move downwards, while another set of polyurethane scraper blades 51 moves upwards to contact the bottom of the conveyor belt 5, completing the replacement operation. At this time, the lead screw motor 62 is activated, driving the lead screw 60 to rotate. This causes the wiping fixture 63 to interact with the threads on the lead screw nut sleeve 64 and the lead screw 60 within the auxiliary base 42, thus... The downward-facing polyurethane scraper blade 51 enters between the two sets of limiting guide plates 65. At the same time, the scraping arc head 52 of the polyurethane scraper blade 51 extends into the arc wheel concave surface 72 of several sets of wiping rollers 71 and contacts the wiping cotton layer 73. Through the relative contact force, the wiping rollers 71 are caused to rotate autonomously, wiping away the stains on the scraping arc head 52 and cooling the scraping arc head 52. When the wiping rollers 71 rotate, the downward-moving wiping cotton layer 73 contacts the cleaning liquid in the cleaning liquid tank 66. Combined with the cleaning action of several sets of elastic cleaning filaments 77, the stains on the wiping cotton layer 73 are thoroughly washed away, maintaining its cleanliness.

[0070] When the second short shaft 53 rotates, it causes the large sprocket 56 to rotate. Through the synchronous chain 84, the small sprocket 83 is accelerated to rotate by one revolution. The camshaft 81 rotates accordingly, causing the two sets of rotating cams 85 to rotate. When the protrusion of the rotating cam 85 moves to the position of the corresponding guide pulley 92, it generates an upward squeezing force, causing the corresponding telescopic rod 90 to move upward. This drives the self-correcting wheels 95 in the two sets of forks 94 to approach the moving chain 3. They partially extend into both sides of the chain 3 and squeeze the misaligned chain 3 through rolling force, achieving the effect of fine-tuning the correction. The chain 3 is maintained regularly. When the protrusion of the rotating cam 85 leaves the position of the guide pulley 92, under the compression force of the return spring 93, the self-correcting wheels 95 and the telescopic rod 90 return to their original positions. Example

[0071] Based on Embodiment 1, the current pneumatic suction pipe 26 is fixed, limiting its suction range. Small raw materials in the machine's hopper 22 need to be manually shoveled into the pneumatic suction pipe 26, which is time-consuming, labor-intensive, and prone to clogging, resulting in poor pneumatic suction performance. To solve these problems, the lower end of the pneumatic suction pipe 26 is fixed inside the positioning tube cover 100, which is fixed to the inner side of the machine's hopper 22. The pneumatic suction pipe 26 is connected to the suction swing pipe 102 via a corrugated pipe 101. The corrugated pipe 101 can extend, retract, and shift within the positioning tube cover 100 as the suction swing pipe 102 moves. Figures 13-16 As shown.

[0072] Specifically, a transmission seat 103 is installed near the upper part of the suction pipe 102. A drive shaft 104 is centrally mounted inside the transmission seat 103. The drive shaft 104 is connected to the inner wall of the transmission seat 103 via a fourth bearing seat 105. One end of the drive shaft 104 is connected to a drive motor 106 via a coupling. The drive motor 106 horizontally passes through the transmission seat 103. A pulley 107 is sleeved in the middle of the drive shaft 104. Figure 13 and Figure 14 As shown.

[0073] In this configuration, the end of the drive shaft 104 furthest from the drive motor 106 extends outward from the transmission seat 103 and is fixed with a crank 115. A connecting rod 114 is hinged to the end of the crank 115. The end of the connecting rod 114 furthest from the crank 115 is connected to the fixing plate 112 via a rotary bearing 113. The fixing plate 112 is installed outside the positioning tube cover 100. Figure 13 and Figure 14 As shown.

[0074] Among them, a rocker arm 111 is hinged to the end of the fixed plate 112 away from the rotating bearing 113. An inner bearing for the drive shaft 104 to pass through is installed at the end of the rocker arm 111 away from the fixed plate 112. The lower end of the rocker arm 111 is sleeved on the outside of the suction pipe 102 by a tube sleeve 110. Figure 13 and Figure 14 As shown.

[0075] Furthermore, a suction pipe port 120 is provided at the lower end of the suction pipe 102. Several sets of scraper blades 121 are evenly welded around the periphery of the suction pipe port 120. The scraping direction of each set of scraper blades 121 is designed according to actual needs. Since the suction pipe 102 has a certain length, it swings within a small range at the pipe sleeve 110 position and changes to a longer swing path at the suction pipe port 120 position. The specific shape of the bottom of the machine body hopper 22 can be designed according to actual conditions, such as... Figure 15 As shown.

[0076] Furthermore, a tube frame 122 is fixed to the outer side of the lower position of the suction tube 102. The tube frame 122 allows the horizontal roller 123 to pass through both sides. The horizontal roller 123 is connected to the tube frame 122 through two sets of tube bearings 124. A second pulley 125 is sleeved in the middle of the horizontal roller 123 and inside the tube frame 122. The second pulley 125 and the first pulley 107 are connected and driven by a transmission belt 126. Figure 15 and Figure 16 As shown.

[0077] The horizontal roller 123 has vertically welded turning blades 127 at both ends. The specific structure of the turning blades 127 can be designed according to actual needs to ensure a suitable turning and feeding effect. The two sets of turning blades 127 have a V-shaped cross-section, which facilitates feeding from the outside to the inside. The lower end of the turning blades 127 includes an elastic steel fork 128. After being compressed and deformed, the elastic steel fork 128 will generate elastic force, which will bounce small raw materials further away, such as... Figure 16 As shown.

[0078] In this embodiment, when the pneumatic suction pipe 26 is sucking material, the drive motor 106 is started, and the drive shaft 104 drives the crank 115 to make a circular motion. The movement of the connecting rod 114 causes the swing arm 111 to swing back and forth within a certain range. Through the connection of the sleeve 110, the suction swing pipe 102 swings synchronously, so that the lower end of the suction swing pipe 102 moves a wide range in the lower position of the material bin 22 of the machine body. Meanwhile, the several sets of scraper blades 121 on the suction pipe opening 120 automatically scrape away the small raw materials that are obstructing the movement of the pipe body as the pipe body moves, and avoid the pipe opening from being blocked, thereby increasing the suction range of the pneumatic suction pipe 26.

[0079] While the drive shaft 104 moves, the first pulley 107 rotates accordingly. Through the transmission belt 126, the second pulley 125 and the horizontal roller 123 rotate. The two sets of turning blades 127 on the horizontal roller 123 make circular motion. During the motion, the two sets of turning blades 127 turn up the small raw materials piled up around them and randomly throw them from the outside to the inside onto the movement path of the suction pipe 120, ensuring that the suction pipe 102 has sufficient and stable small raw materials for pneumatic suction.
