[0038] Example 1

[0039] Please see Figure 1-7 In this embodiment of the present invention, a feeding device for a laser tube cutting machine includes: a support frame 100, two conveying mechanisms 200 and a feeding mechanism 300. A bearing shell 110 is fixedly connected to the top of the support frame 100, and connecting holes 111 are provided on both sides of the bearing shell 110. Sliding grooves 112 are provided at the bottom of the two inner sidewalls of the bearing shell 110. The two conveying mechanisms 200 are both disposed inside the bearing shell 110. The conveying mechanism 200 includes a guide plate 210. The top of the guide plate 210 is rotatably connected to the top of the inner side of the corresponding connecting hole 111. Rotating blocks 220 are rotatably connected to the bottom of both ends of the guide plate 210, and a telescopic plate 221 is rotatably connected to the bottom between the two rotating blocks 220. A shifting component is provided on one side of the telescopic plate 221, and a blocking component is provided at the bottom of the telescopic plate 221. The feeding mechanism 300 is disposed at the bottom of the bearing shell 110.

[0040] Specifically, two movable components are used to easily adjust the position of the two telescopic plates 221, so that the distance between the two telescopic plates 221 can be adapted to pipes of different sizes. Two conveying mechanisms 200 are used in conjunction to facilitate the storage of multiple pipes. A feeding mechanism 300 is used to facilitate the movement of the pipes by rubbing them, which is convenient for feeding the laser pipe cutting machine. The two conveying mechanisms 200 and the feeding mechanism 300 work together to facilitate the conveying and feeding of pipes of different sizes.

[0041] like Figure 3-7 As shown, in this embodiment, the displacement assembly includes: a limiting shell 250 and an electric push rod 260. The limiting shell 250 is fixedly connected to one side of the telescopic plate 221. One end of the electric push rod 260 is fixedly connected to the inner wall of the bearing shell 110. The output end of the electric push rod 260 is fixedly connected to a limiting block 261, and the limiting block 261 is slidably connected to the inside of the limiting shell 250. The blocking assembly includes: a fixing shell 230 and an electric push rod 240. The fixing shell 230 is fixedly connected to the bottom of the corresponding telescopic plate 221. Both ends of the fixing shell 230 are fixedly connected to sliders, and the sliders are connected to the corresponding... The slide 112 is slidably connected. One end of the electric push rod 240 is fixedly connected to an inner side wall of the fixed housing 230. The output end of the electric push rod 240 is fixedly connected to a baffle 241, and the baffle 241 is slidably inserted into the fixed housing 230. The feeding mechanism 300 includes: a connecting housing 310, a bearing plate 320, and two electric push rods 330. The connecting housing 310 is located at the bottom of the bearing housing 110. Two adjusting components are provided on the connecting housing 310. The bearing plate 320 is fixedly connected to the top of the connecting housing 310. An arc-shaped groove 321 is provided at the middle position of the top of the connecting housing 310. Furthermore, the top of the connecting shell 310 has two sliding through holes 322, and the top of the support plate 320 is provided with two rubbing components, which are opposite to each other. Two electric push rods 330 are fixedly connected to the inner bottom surface of the support frame 100, and the output ends of the two electric push rods 330 are respectively fixedly connected to both ends of the support plate 320. The rubbing components include: a rectangular shell 350, multiple rotating rods 370, and a motor 380. The rectangular shell 350 is located on the top of the support plate 320, and multiple connecting holes 351 are provided on one side of the rectangular shell 350. The multiple rotating rods 370 are all connected to the rectangular shell 350. The internal rotating connection of 350 is such that the top of the rotating rod 370 is fitted with a gear 371, and the outer sides of the multiple gears 371 are connected to a toothed belt 373. Both inner sidewalls of the rectangular shell 350 are in contact with the outer sidewalls of the toothed belt 373. The bottom of the rotating rod 370 is fitted with a rubbing wheel 372, which passes through the interior of the connecting hole 351 and extends to one side of the rectangular shell 350. The top of the second motor 380 is fixedly connected to the bottom of one end of the rectangular shell 350, and the output end of the second motor 380 passes through the sidewall of the rectangular shell 350 and is fixedly connected to the bottom of the corresponding rotating rod 370.

[0042] In this embodiment, by activating the second electric push rod 260, the limiting block 261 is moved, thereby causing the limiting shell 250 and the telescopic plate 221 to move. This facilitates the adjustment of the distance between the two telescopic plates 221, ensuring that the distance between them corresponds to the outer diameter of pipes of different sizes. Furthermore, by activating the two electric push rods 240 to retract, the two baffles 241 move into the interior of the two fixed shells 230, thereby facilitating the falling of the lowest pipe among the multiple pipes inside the conveying mechanism 200 to the top of the arc-shaped groove 321. When a pipe moves out between the two telescopic plates 221, the two baffle assemblies can be used to block and limit the remaining pipes. Then, by activating the electric push rod 330 to retract, the bearing plate 320 and the pipe on it are moved to the appropriate position. Then, by activating the two motors 380, the corresponding rotating rods 370 and gears 371 are driven to rotate. The toothed belt 373 works in conjunction to make multiple gears 371 rotate, thereby making multiple rubbing wheels 372 rotate. The rotating multiple rubbing wheels 372 facilitate the rubbing and conveying of the pipe, making the operation more convenient.

[0043] Example 2

[0044] Based on Embodiment 1, in order to make the two rubbing components applicable to pipes of different sizes.

[0045] like Figure 4-5 As shown, in this embodiment, the adjustment component includes: two L-shaped plates 340 and a motor 360. Both L-shaped plates 340 are slidably connected to the interior of the connecting shell 310. A telescopic plate 342 is fixedly connected to the top of the L-shaped plate 340, and the top of the telescopic plate 342 is fixedly connected to the bottom of the corresponding rectangular shell 350. The motor 360 is fixedly connected to one side of the connecting shell 310. The output end of the motor 360 passes through the side wall of the connecting shell 310 and is fixedly connected to a bidirectional lead screw 361. The bidirectional lead screw 361 is screwed to the two L-shaped plates 340. Both ends of the inner bottom surface of the L-shaped plate 340 are fixedly connected to an electric push rod 341, and the output end of the electric push rod 341 is fixedly connected to the bottom of the corresponding rectangular shell 350.

[0046] In practice, by activating two electric push rods 341, the rectangular shell 350 is moved, which facilitates the adjustment of the height of the two rubbing components. Then, by activating motor 360, the bidirectional lead screw 361 is rotated, causing the two L-shaped plates 340 to move. This moves the two telescopic plates 342 and the two rubbing components to the appropriate positions, thus enabling the feeding mechanism 300 to be suitable for pipes of different sizes, improving the practicality of the feeding device of the laser pipe cutting machine.

[0047] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
