[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figure 1-2 As shown, this utility model provides a technical solution: an automatic pipe feeding mechanism, including a frame 101, a feeding mechanism 200, and a feeding mechanism 300; the feeding mechanism 200 and the feeding mechanism 300 are mounted on the frame 101. The feeding mechanism 200 realizes the one-to-one arrangement and feeding of pipes, and the feeding mechanism 300 realizes the axial conveying of materials. Through the cooperation between the feeding mechanism 200 and the feeding mechanism 300, the purpose of this solution is to achieve automated feeding.

[0018] like Figure 3-4 As shown, the feeding mechanism 200 includes a set of feeding plates 201, inclined plates 202, baffle rods 203, feeding channels 204, top-feeding devices, and feed troughs 207. The feeding plates 201 are mounted on the frame 101. In this design, there are four pairs of feeding plates 201, and their number can be designed according to the size of the pipe material to be processed. The feeding plates 201 are spaced apart. An inclined plate 202 is provided on the upper end face of the feeding plate 201. The baffle rods 203 are installed on one side of the feeding plate 201. The inclined plates 202 and the baffle rods 203 together form the feeding channel 204. The pipe materials to be processed are arranged one by one on the inclined plates 202, and the bottom pipe material is blocked by the baffle rods 203. This can be understood as placing all the pipes on the inclined plate 202, and then, under the constraint of the baffle rod 203, arranging all the pipes within the feeding channel 204 to facilitate the next step of the operation.

[0019] On the lower side of the feeding channel 204, the top material device is installed at the end of the inclined plate 202, and the feed trough 207 is installed at one end of the feeding plate 201. The feed trough 207 is lower than the lowest end of the feeding channel 204. The top material device lifts the tubes one by one from the feeding channel 204 into the feed trough 207. The feed trough 207 is used to temporarily store the individual tubes that are lifted out by the top material device. The feeding device includes a feeding block 205 and a feeding cylinder 206, the feeding cylinder 206 being mounted on the side of the feeding plate 201; the feeding block 205 being mounted on the telescopic shaft of the feeding cylinder 206, and the top surface of the feeding block 205 having the same inclination as the inclined plate 202; the inclined plate 202, the feeding block 205, and the baffle rod 203 together form the feeding channel 204; Figure 5 As shown, the lowest tube in the feeding channel 204 is located on the top material block 205, and the other tubes are located on the inclined plate 202. The top material cylinder 206 drives the top material block 205 to perform telescopic movement to push the tube located at the lowest end of the feeding channel 204 into the feed trough 207. Through the above structure, the tubes are fed one by one in sequence.

[0020] Considering the different diameters of the pipes to be processed in actual production, in order to ensure that the top material block 205 can only eject one pipe at a time, the top material cylinder 206 is installed on the side of the feeding plate 201 through the top material bracket. The top material bracket is provided with waist holes, so that the top material cylinder 206 can be adjusted left and right. The material stop rod 203 is provided with material stop waist holes. The material stop rod 203 is fixed to the feeding plate 201 by bolts, so that the material stop rod 203 can also be adjusted left and right, so that only one pipe can stay on the top of the top material block 205 at a time.

[0021] To prevent the pipes from accumulating at the bottom of the feeding channel 204 under gravity, which could prevent them from being ejected one by one, a baffle bracket 208, a limiting baffle 209, and an adjustment knob 210 are provided above the inclined plate 202. The baffle bracket 208 is mounted on the feeding plate 201, and the limiting baffle 209 is mounted on the baffle bracket 208 via the adjustment knob 210. The extension direction of the limiting baffle 209 is the same as the inclination direction of the inclined plate 202. A gap is formed between the limiting baffle 209 and the inclined plate 202, and the size of this gap allows only one pipe to pass through at a time, so that the pipes are arranged one by one to form the feeding channel 204.

[0022] like Figure 9-11As shown, the feeding mechanism 300 is mounted on the frame 101 and is on the same axis as the feeding trough 207. The feeding mechanism 300 includes a roller feeding device that clamps the pipe material and drives it to move linearly. The roller feeding device includes a mounting base 301, a guide rail 302, a first slide 303, a second slide 304, a dual-axis cylinder 305, a driving feeding wheel 306, a driven feeding wheel 307, and a drive motor 308. The guide rail 302 is mounted on the mounting base 301, and the first slide 303 and the second slide 304 are slidably mounted on the guide rail 302. The dual-axis cylinder 305 is located on the mounting base 301. On the 01, the telescopic shafts of the dual-axis cylinder 305 are connected to the first slide 303 and the second slide 304 respectively. The active feed wheel 306 is mounted on the first slide 303, and the driven feed wheel 307 is mounted on the second slide 304. The active feed wheel 306 and the driven feed wheel 307 are arranged opposite to each other. The output shaft of the drive motor 308 is connected to the active feed wheel 306 through a pulley and a belt. In this way, the action of the dual-axis cylinder 305 will cause the first slide 303 and the second slide 304 to move relative to each other, and finally make the active feed wheel 306 and the driven feed wheel 307 move relatively closer or relatively farther away at the same time.

[0023] A pulley is fixed on the output shaft of the drive motor 308, and a pulley is also fixed on the shaft end of the active feed wheel 306. The two pulleys are connected by a belt for transmission. The drive motor 308 is configured to drive the active feed wheel 306 to rotate. The rotation of the active feed wheel 306 is achieved by the drive motor 308. The simultaneous relative approach or relative distance between the active feed wheel 306 and the driven feed wheel 307 is controlled by the dual-axis cylinder 305, thereby realizing the clamping and releasing of the tube material, and achieving the function of clamping the tube material and conveying the material in a straight line.

[0024] A first sensor 309 is provided on one side of the mounting base 301 to detect whether the tube material exists between the active feed wheel 306 and the driven feed wheel 307.

[0025] See Figures 12-14A pipe straightening device 400 is also provided on the frame 101. The pipe straightening device 400 and the feed chute 207 are on the same axis. The pipe straightening device 400 includes a mounting frame 401, a guide plate 402, a sliding plate 403, a guide groove 404, a cylinder 405, a guide rod 406, an upper sliding plate 407, a lower sliding plate 408, a slip ring 409, an upper straightening wheel 410, and a lower straightening wheel 411. The mounting frame 401 is mounted on the frame 101, the guide plate 402 is mounted on the mounting frame 401, the sliding plate 403 is movably mounted on the guide plate 402, and the sliding plate 403 is provided with a pair of inclined guide grooves 404. The cylinder 405 is mounted on the mounting frame 401, and the telescopic rod of the cylinder 405 is connected to the sliding plate 403. The guide rod 406 is vertically mounted on the mounting bracket 401. The upper slide plate 407 and the lower slide plate 408 are movably mounted on the guide rod 406, respectively. Slip rings 409 are provided on the upper slide plate 407 and the lower slide plate 408. The slip rings 409 are movably mounted in the guide groove 404. The upper straightening wheel 410 is mounted on the upper slide plate 407, and the lower straightening wheel 411 is mounted on the lower slide plate 408. The extension and retraction of the cylinder 405 drives the sliding plate 403 to move left and right, thereby causing the slip rings 409 to slide in the guide groove 404. This allows the upper slide plate 407 and the lower slide plate 408 to move up and down on the guide rod 406. Finally, the upper straightening wheel 410 and the lower straightening wheel 411 move closer and further apart in the vertical direction, thereby clamping and straightening the pipe material and allowing the pipe material to move in one direction without deviation.

[0026] A second sensor 412 is provided on the top of the mounting bracket 401 to detect whether the pipe material has moved to the pipe material straightening device 400.

[0027] To better understand the specific implementation principle of this solution, the steps of the automatic feeding process are briefly introduced below.

[0028] S1. Place multiple pipes on the feeding channel 204. The top-loading cylinder 206 is ready to operate. (See below) Figure 5 ; S2. The ejector cylinder 206 extends, ejecting a tube into the feed chute 207. (See below) Figure 6 , Figure 7 ; S3. The top-loading cylinder 206 retracts the top-loading block 205, and the tubular material is rearranged within the feeding channel 204. (See below) Figure 8 ; S4. After the tube enters the feed trough 207, when the first sensor 309 detects the tube, the dual-shaft cylinder 305 is activated, the active feed wheel 306 and the driven feed wheel 307 move closer to each other to complete the tube clamping action. At the same time, the drive motor 308 starts, the active feed wheel 306 rotates, and the tube moves in a straight line. S5. When the tube material moves to the tube material straightening device 400, the second sensor 412 detects the tube material, the cylinder 405 is activated, the upper straightening wheel 410 and the lower straightening wheel 411 move closer to each other to complete the clamping action. While the tube material is driven forward by the roller feeding device, it is straightened by the straightening wheel and moves in one direction.

[0029] S6. Once the second sensor 412 detects that the pipe material delivery is complete, the above cycle is repeated.

[0030] By simplifying the structure of the feeding mechanism and the infeeding mechanism, the number of moving parts is reduced, thus realizing automatic feeding and conveying of pipe materials.

[0031] like Figure 15 As shown, to feed materials to a multi-station laser cutting machine, two automatic tube feeding mechanisms are combined. The two automatic tube feeding mechanisms are symmetrically arranged and connected by a connecting plate 102. The frame 101 of the automatic tube feeding mechanism has connecting holes, and the connecting plate 102 has connecting waist holes. The connecting plate 102 bolts the two frames 101 together, and the spacing between the two automatic tube feeding mechanisms is adjusted through the connecting waist holes. Figure 16 The diagram shows the usage status of this dual-line feeder in conjunction with a dual-station laser cutting machine.

[0032] The roller feeding device of the dual-line feeder adopts a staggered design to avoid mutual interference. The dual-line feeder can share a set of control system and pneumatic and electrical drive system, and the two feeding mechanisms execute the same motion commands, thereby further saving material costs.

[0033] In summary, this design can realize automatic feeding of single or dual pipes, and has a simple structure, low cost, and greatly improves production efficiency.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
