[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0027] A pipe-by-pipe feeding mechanism, such as Figures 1-8 As shown, the assembly includes a base plate 1, a material guiding component 2, a material storage component 3, a material blocking component 4, and a first driving component 5. The material guiding component 2 is arranged on the base plate 1, and the material storage component 3 is located on one side of the base plate 1. The material storage component 3 is used to store the pipes. By moving up and down, the pipes are fed into the material guiding component 2, and then the material guiding component 2 pushes the pipes out one by one. Specifically:

[0028] The material guiding assembly 2 includes a material guiding bracket 21, a push rod 22, and a stop block 23. The top of the material guiding bracket 21 is provided with a first inclined guide surface 211, and the lower end of the first inclined guide surface 211 is provided with a stop block 212. The push rod 22 is slidably disposed on the material guiding bracket 21 and is located on the side of the stop block 23. The push rod 22 is connected to the first driving assembly 6 and is driven to move up and down reciprocally by the first driving assembly 5. The material guiding bracket 21 is provided with a guide hole, and the push rod 22 is slidably disposed in the guide hole. The tubes are arranged on the first inclined guide surface 211. The first tube is blocked by the stop block 23. The push rod 22 is located below the first tube. By moving the push rod 22 upward, the first tube is lifted upward and passes the stop block 23. The tube slides downward along the upper surface of the stop block 23, thereby realizing the single tube sliding into the feeding mechanism.

[0029] The storage assembly 3 includes a lifting assembly 31 and several storage racks 32 arranged on the lifting assembly 31. These storage racks 32 collectively support the pipe, and the combined length of the storage racks 32 is greater than the length of the pipe. The lifting assembly 31 drives the storage racks 32 to move up and down. The storage racks 32 are L-shaped, and their bottoms have a second inclined guide surface 321 that slopes towards the guide assembly 2. The storage racks 32 and the sidewall of the guide bracket 21 form a cavity for storing the pipe.

[0030] The material blocking assembly 4 includes a stop lever 41 and a second drive assembly 42 that drives the stop lever 41. The stop lever 41 is rotatably mounted on the material guide bracket 21, and the second drive assembly 42 drives the stop lever 41 to swing back and forth. When blocking material, the stop lever 41 protrudes from the first inclined guide surface 211, and a temporary storage position for storing a single tube is formed between the stop lever 41 and the first inclined guide surface. When releasing material, the stop lever 41 rotates to below the first inclined guide surface 211.

[0031] In use, the lifting assembly 42 drives the storage rack 32 to move upward, so that the pipes stored on the storage rack 32 are higher than the guide support 21. At this time, the pipes will move towards the stop bar 41. Then the lifting assembly 42 descends, so that the accumulated pipes are lower than the guide support 21. One pipe will remain in the temporary storage position. The stop bar 41 is rotated so that the stop bar 41 is lower than the first inclined guide surface 211. The pipe slides along the first inclined guide surface 211 to the stop block 23. The first driving assembly 5 drives the top rod 22 to move upward, so as to lift the pipe and make it slide down the upper surface of the stop block 23 and fall into the feeding mechanism.

[0032] In one embodiment, such as Figures 1-8As shown, the material guiding assembly 2 also includes an anti-jump plate 24, which is disposed above the first inclined guide surface 211. A guide groove for a single pipe arrangement is formed between the anti-jump plate 24 and the first inclined guide surface 211. Specifically, the anti-jump plate 24 can be fixed to the base plate 1 or the material guiding bracket 21. To prevent the connection from affecting the movement of the pipe, an area for placing the feeding mechanism is formed between the anti-jump plate 24 and the material guiding bracket 21. Preferably, a guide portion 241 is provided at one end of the anti-jump plate 24 to increase the opening size of the guide groove, facilitating the entry of the pipe into the guide groove.

[0033] In one embodiment, such as Figures 1-8 As shown, the first drive assembly 5 includes a first connecting rod 51, a second connecting rod 52, a first drive shaft 53, and a first actuator 54. One end of the first connecting rod 51 is hinged to the top rod 22, and the other end is hinged to one end of the second connecting rod 52. The other end of the second connecting rod 52 is fixed to the first drive shaft 53. The first drive shaft 53 is rotatably mounted on the guide support 21, and the first actuator 54 drives the first drive shaft 53 to reciprocate.

[0034] In the above embodiments, such as Figures 1-8 As shown, the first actuator 54 includes a first drive rod 541 and a first hydraulic cylinder 542. The first hydraulic cylinder 542 is hinged to the base plate 1. The first drive rod 541 is fixed to the first drive shaft 53, and the first drive rod 541 is hinged to the first hydraulic cylinder 542. The first drive rod 541 has a waist-shaped hole 543, and the telescopic rod of the first hydraulic cylinder 542 is floatingly connected to the waist-shaped hole 543.

[0035] The first hydraulic cylinder 542 expands and contracts, thereby driving the first drive shaft 53 to reciprocate through the first drive rod 541, which in turn drives the push rod 22 to move up and down reciprocally.

[0036] In one embodiment, such as Figures 1-8 As shown, the lifting assembly 31 includes a bottom support 311, a lifting platform 312, a guide rod 313, and a third actuator 314. The bottom support 311 is fitted with a guide sleeve, and the guide rod 313 is located at the bottom of the lifting platform 311, slidably connected to the guide sleeve. The third actuator 314 is mounted on the bottom support 311 and connected to the lifting platform 312, driving the lifting platform 312 to move up and down. The third actuator 314 can be a hydraulic cylinder or an electric cylinder.

[0037] In one embodiment, such as Figures 1-8As shown, the second drive assembly 42 includes a second drive shaft 421, a second drive rod 422, and a second hydraulic cylinder 423. The second drive shaft 421 is rotatably mounted on the guide bracket 21. A stop lever 41 is fixed to the second drive shaft 421. The second drive rod 422 is fixed to the second drive shaft 421 and hinged to the second hydraulic cylinder 423. The second hydraulic cylinder 423 is hinged to the base plate 1. The second drive rod 422 is driven by the second hydraulic cylinder 423 to rotate the second drive shaft 421. A set of power equipment drives multiple stop levers 41 to move synchronously.

[0038] In the above embodiments, such as Figures 1-8 As shown, a locking screw is provided on the second drive rod 422, which locks and fixes the second drive rod 422 to the second drive shaft 421. That is, the drive rod 421 has a radially provided connecting hole that mates with the second drive shaft 421, and also has a threaded hole that communicates with the connecting hole. The locking screw mates with the threaded hole, thereby fixing the second drive rod 422 and the second drive shaft 421 through the locking screw.

[0039] In one embodiment, such as Figures 1-8 As shown, when the stop lever 41 is in the blocking position, the angle between the stop lever 41 and the base plate 1 is an acute angle. This causes the stop lever 41 to tilt towards the storage rack 32, preventing the pipes from stacking on the temporary storage position 2.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of implementation of the present utility model. Any modifications or equivalent substitutions to the present utility model without departing from the spirit and scope thereof should be covered within the protection scope of the claims of the present utility model.
