[0029] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0030] Understandably, referring to Figure 1 , Figure 3and Figure 4 The pipe feeding device of this utility model includes a frame 100, a material handling mechanism 200, and a material discharging mechanism 300. The frame 100 is provided with two guide ramps 110 spaced apart, forming a material handling channel 120 between the two guide ramps 110. The material handling mechanism 200 includes a first driving member 210 and two material handling frames 220, which are respectively arranged on both sides of the material handling channel 120. The first driving member 210 drives the two material handling frames 220 to move synchronously up and down within the frame 100. The material handling frames 220 are used to receive the pipe. The material discharging mechanism 300... The device includes two sets of feeding components 310, which are respectively arranged on both sides of the discharge end of the guide ramp 110. Each feeding component 310 includes a fixed step plate 311, a movable step plate 312, and a second driving member 313. Both the fixed step plate 311 and the movable step plate 312 are provided with multiple inclined surfaces 314 at intervals along the vertical direction, allowing the pipe to roll on the inclined surfaces 314. The second driving member 313 is used to drive the movable step plate 312 to move up and down, so that the pipe rises alternately on the fixed step plate 311 and the movable step plate 312.

[0031] Two guide ramps 110 are spaced apart on the frame 100, forming a material handling channel 120 between them, allowing the handcart to be positioned within the channel. Two material handling frames 220 are respectively positioned on either side of the material handling channel 120. A first drive unit 210 drives the two material handling frames 220 to move synchronously up and down within the frame 100, enabling the frames to receive pipes from the handcart and lift them upwards, allowing the pipes to be removed from the handcart. The handcart then exits the material handling channel 120. The first drive unit 210 then drives the material handling frames 220 downwards, placing the pipes on the guide ramps 110, which guide the pipes upwards. The material assembly 310 rolls, the fixed step plate 311 is fixedly connected to the frame 100, and the movable step plate 312 is connected to the movable end of the second drive member 313. The second drive member 313 drives the movable step plate 312 to move up and down, so that the pipe can roll on the inclined surface 314 on the fixed step plate 311 and the movable step plate 312, so that the pipe can rise alternately on the fixed step plate 311 and the movable step plate 312, thereby realizing the automatic output of pipes one by one, replacing manual feeding, and improving the efficiency and stability of feeding.

[0032] It should be noted that the length of the pipe is greater than the width of the trolley so that both ends of the pipe can protrude from the trolley. The trolley is pushed into the material picking channel 120 so that the pipe can be arranged below the material picking frame 220. The first driving member 210 drives the two material picking frames 220 to rise synchronously so that the two material picking frames 220 can support both ends of the pipe, thereby allowing the pipe to be removed from the trolley.

[0033] In addition, the fixed step plate 311 is located at the discharge end of the guide ramp 110, and the inclined surface 314 at the bottom of the movable step plate 312 can move to below the guide ramp 110. When the pipe rolls against the fixed step plate 311 through the guide ramp 110, the inclined surface 314 at the bottom of the movable step plate 312 is below the pipe. The second driving member 313 drives the movable step plate 312 to rise, and the inclined surface 314 on the movable step plate 312 can lift the pipe from the guide ramp 110, allowing the pipe to roll on the inclined surface 314. Then, the second driving member 313 drives the movable step plate 312 to fall, placing the pipe on the inclined surface 314 of the fixed step plate 311. The above process is repeated, allowing the pipe to rise alternately on the fixed step plate 311 and the movable step plate 312, thereby enabling the pipe to be output one by one.

[0034] The length of the inclined plane 314 is greater than the outer diameter of the pipe but less than twice the outer diameter of the pipe, so that one inclined plane 314 can only accommodate one pipe, thus avoiding the simultaneous output of multiple pipes.

[0035] Specifically, the first driving component 210 can be a linear cylinder, an electric cylinder, or a motor combined with chain drive, belt drive, etc., which can drive the material picking frame 220 to rise and fall; the second driving component 313 can be a linear cylinder, an electric push rod, a linear slide module, etc., which are not limited here.

[0036] Understandably, referring to Figure 3 The material handling mechanism 200 also includes a material distribution component 230, which includes a baffle plate 231 and a third drive member 232. The baffle plate 231 is rotatably connected to the frame 100 and is arranged above the guide ramp 110. The third drive member 232 is used to drive the baffle plate 231 to rotate. The baffle plate 231 is rotatably connected to the frame 100. The fixed end of the third drive member 232 is hinged to the frame 100, and the movable end of the third drive member 232 is hinged to the baffle plate 231. The third drive member 232 can drive the baffle plate 231 to rotate on the frame 100, thereby facilitating the adjustment of the distance between the baffle plate 231 and the guide ramp 110. This prevents the pipes from rolling on the guide ramp 110, thus avoiding the chaos caused by multiple pipes simultaneously entering the discharge end of the guide ramp 110, reducing the jamming problem caused by disorderly rolling of pipes, and improving the working stability of the entire feeding device.

[0037] It should be noted that when pipes need to enter the discharge mechanism 300, the third driving component 232 drives the baffle plate 231 to rotate, thereby increasing the distance between the baffle plate 231 and the guide ramp 110, so that the pipes can pass through; when too many pipes accumulate in the discharge mechanism 300, the third driving component 232 drives the baffle plate 231 to rotate, thereby decreasing the distance between the baffle plate 231 and the guide ramp 110, thus blocking the pipes from passing through.

[0038] The third drive component 232 can be a linear cylinder, an electric actuator, a linear slide module, etc., and is not limited here.

[0039] Specifically, refer to Figure 3 and Figure 5 The material distribution assembly 230 also includes an adjusting plate 234. The adjusting plate 234 has an adjusting groove 235, and a fastener 236 passes through the adjusting groove 235. The fastener 236 is threadedly connected to the baffle plate 231. The adjusting plate 234 has an adjusting groove 235, and the fastener 236 passes through the adjusting groove 235 so that the fastener 236 can slide along the length of the adjusting groove 235. This allows for easy adjustment of the position of the adjusting plate 234 on the baffle plate 231, and facilitates adjustment of the distance between the adjusting plate 234 and the guide ramp 110. This adapts to pipes of different diameters and improves versatility.

[0040] It should be noted that during adjustment, the fastener 236 is loosened so that it can slide in the adjustment groove 235 to adjust the distance between the adjustment plate 234 and the guide ramp 110. Then the fastener 236 is tightened so that the adjustment plate 234 can be locked on the baffle plate 231, which can accommodate pipes of different diameters.

[0041] Among them, fastener 236 can be bolts, screws, etc., which will not be described in detail here.

[0042] Understandably, referring to Figures 1 to 3 The material handling mechanism 200 also includes a material shaking assembly 240, which includes a material shaking frame 241 and a fourth driving member 242. One end of the material shaking frame 241 is hinged to the guide ramp 110, and the fourth driving member 242 is used to drive the material shaking frame 241 to rotate. One end of the material shaking frame 241 is hinged to the guide ramp 110, and the fourth driving member 242 drives the material shaking frame 241 to rotate around the hinge point, so that the material shaking frame 241 can push the pipe to rise, avoiding the pipe from being blocked, stacked or placed irregularly, which would affect the subsequent feeding process. This allows the pipe to roll more smoothly along the guide ramp 110 to the discharge mechanism 300, improving the smoothness and stability of the pipe feeding.

[0043] It should be noted that the fourth driving component 242 can be a motor, a rotary cylinder, a linear cylinder, an electric actuator, etc., and is not limited here. When the fourth driving component 242 is a rotary driving element such as a motor or a rotary cylinder, the output end of the fourth driving component 242 is connected to the hinge point of the shaking frame 241; when the fourth driving component 242 is a linear driving element such as a linear cylinder or an electric actuator, the movable end of the fourth driving component 242 abuts against the end of the shaking frame 241 away from the hinge point.

[0044] Specifically, refer to Figures 1 to 3The fourth driving component 242 includes a first connecting plate 243, a second connecting plate 244, a connecting rod 245, and a first power component 246. The two ends of the first connecting plate 243 are respectively hinged to the guide ramp 110 and the connecting rod 245. The second connecting plate 244 is hinged to the guide ramp 110. One end of the second connecting plate 244 is hinged to the connecting rod 245, and the other end of the second connecting plate 244 abuts against the shaking frame 241. The first power component 246 is used to drive the connecting rod 245 to move. The first connecting plate 243 is hinged at both ends to the guide ramp 110 and the connecting rod 245, respectively. The second connecting plate 244 is hinged to the guide ramp 110, and one end of the second connecting plate 244 is hinged to the connecting rod 245, while the other end abuts against the shaking frame 241, so that the connecting rod 245 can move in translation. The first power member 246 pushes the connecting rod 245 to move, so that the second connecting plate 244 can push the shaking frame 241 to rotate around the hinge point, so that the shaking frame 241 can push the pipe on the guide ramp 110, avoiding multiple pipes from blocking each other and improving the smoothness of material picking.

[0045] It should be noted that the distance between the hinge points at both ends of the first connecting plate 243 is equal to the distance between the two hinge points of the second connecting plate 244, enabling the connecting rod 245 to move stably in translation. The first power component 246 can be a linear cylinder, an electric actuator, etc., which will not be described in detail here.

[0046] Specifically, refer to Figure 2 A roller 247 is rotatably connected to the end of the second connecting plate 244 away from the connecting rod 245, and the roller 247 abuts against the shaking frame 241. By setting the roller 247 on the second connecting plate 244, the sliding friction between the second connecting plate 244 and the shaking frame 241 can be transformed into rolling friction, reducing the frictional force between the second connecting plate 244 and the shaking frame 241, reducing energy loss, making it easier and less strenuous for the first power component 246 to drive the connecting rod 245 to move, improving transmission efficiency, reducing wear on components, extending the service life of the second connecting plate 244 and the shaking frame 241, reducing equipment maintenance costs and failure rate, and the rolling motion of the roller 247 is more stable, making the shaking of the shaking frame 241 more uniform and stable, thereby improving the shaking and sorting effect on the pipes on the guide ramp 110.

[0047] Understandably, referring to Figure 1 and Figure 4The discharge mechanism 300 also includes a synchronization component 320, which includes a connecting shaft 321, two sets of synchronization pulleys 322 and two synchronization belts 323. The synchronization pulleys 322 and the synchronization belts 323 are in one-to-one correspondence. The synchronization pulleys 322 are used to tension the synchronization belts 323. The connecting shaft 321 is connected to the two sets of synchronization pulleys 322 for transmission. The synchronization belts 323 are fixedly connected to the movable step plate 312. Synchronous pulley set 322 is used to tension synchronous belt 323. Synchronous belt 323 corresponds one-to-one with movable step plate 312. The two sets of synchronous pulley sets 322 are connected by connecting shaft 321 so that the two synchronous belts 323 can rotate synchronously. This ensures that the movable step plates 312 in the two sets of feeding components 310 move synchronously, effectively avoiding the problem of pipe tilting caused by asynchronous movement of the movable step plates 312 on both sides. This allows the pipes to rise smoothly and alternately on the inclined surface 314 of the fixed step plate 311 and the movable step plate 312 and be output one by one, improving the stability and reliability of pipe feeding.

[0048] Understandably, referring to Figure 1 The frame 100 is equipped with multiple guide wheels 130, which are respectively arranged on both sides of the material picking channel 120. By setting multiple guide wheels 130 on both sides of the material picking channel 120, the handcart can be guided smoothly into the material picking channel 120, ensuring the accurate positioning of the handcart within the material picking channel 120. This improves the accuracy and stability of material picking and reduces collisions and scrapes to the frame 100 caused by misalignment between the handcart and the material picking channel 120, thus contributing to improved reliability.

[0049] Understandably, referring to Figure 1 The first driving component 210 includes a second power component 211, multiple guide posts 212, and multiple lead screws 213. The guide posts 212 and lead screws 213 are both arranged vertically on the frame 100. The material picking frame 220 is slidably connected to the guide posts 212, and the lead screws 213 are threadedly connected to the material picking frame 220. The second power component 211 drives the lead screws 213 to rotate. Since the guide posts 212 and lead screws 213 are both arranged vertically on the frame 100, the second power component 211 drives the lead screws 213 to rotate, enabling the lead screws 213 to move the material picking frame 220 along the axial direction of the guide posts 212. This drives the material picking frame 220 to move up and down, allowing it to accurately support both ends of the material and improving the accuracy of material picking.

[0050] It should be noted that each material picking frame 220 corresponds to at least one guide post 212 and one lead screw 213, so that the material picking frames 220 on both sides can move up and down stably.

[0051] In addition, the second power component 211 can be a drive element such as an electric motor or a pneumatic motor. Multiple lead screws 213 can be connected to the second power component 211 through chain drive, belt drive or other means, so that one second power component 211 can drive multiple lead screws 213 to rotate synchronously, and the two material picking frames 220 can move up and down synchronously.

[0052] Understandably, referring to Figure 1 The frame 100 is also equipped with a fifth drive unit 141 and a door panel 142. The door panel 142 is located at the input end of the material handling channel 120. The fifth drive unit 141 is used to drive the door panel 142 to move up and down. The fixed end of the fifth drive unit 141 is fixedly connected to the frame 100, and the movable end of the fifth drive unit 141 is connected to the door panel 142. The fifth drive unit 141 can drive the door panel 142 to move up and down, so that the door panel 142 can open or close the material handling channel 120, making the operation of the pipe feeding device stable, preventing the material handling process of multiple handcarts from overlapping and becoming chaotic, and improving the stability of the feeding process.

[0053] It should be noted that the fifth drive component 141 can be a linear cylinder, an electric actuator, a linear slide module, etc., which will not be described in detail here.

[0054] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
