[0025] The following is combined with Figure 1-5 This application is described in further detail.

[0026] The present application embodiment discloses an auxiliary feeding device for a laser tube cutting machine. Figure 1 The auxiliary feeding device of the laser tube cutting machine includes a placement box 1 placed on the ground and a conveying assembly 2 arranged between the placement box 1 and the feed port of the laser tube cutting machine. The placement box 1 is used to store the tubes to be processed. It has a stable structure and a moderate capacity, which can meet the continuous working requirements of the laser tube cutting machine. The conveying assembly 2 is responsible for smoothly and accurately transferring the tubes from the placement box 1 to the feed port of the laser tube cutting machine.

[0027] Reference Figure 1 and Figure 2 The conveying assembly 2 includes a conveying platform 21 and a plurality of conveying blocks 22 that can move around the conveying platform 21. The conveying platform 21 is firmly placed on the ground, and its top surface is flat to support the movement of the conveying blocks 22. The conveying blocks 22 are evenly distributed on the conveying platform 21 and fixed in appropriate positions. Each conveying block 22 is provided with a conveying groove 221, and the size of these conveying grooves 221 matches the pipe to be processed, which can ensure that the pipe is stably embedded during the conveying process without rolling or deviation.

[0028] The conveying assembly 2 also includes a conveyor belt 23 and a driving member 24 for driving the conveyor belt 23. The conveying block 22 is fixed to the conveyor belt 23 and moves synchronously with the conveyor belt 23. During the implementation process, workers use an overhead crane to lift the pipe into the placement box 1. Then, the conveying assembly 2 is started, and the conveying block 22 begins to sequentially transfer the pipe from the placement box 1 to the feed port of the laser pipe cutting machine. Due to the presence of the conveying trough 221, the pipe can remain stable during the conveying process, effectively avoiding the problems of shaking, slipping and deviation that are prone to occur in traditional feeding methods.

[0029] Reference Figure 1 and Figure 2 The driving member 24 includes an active roller 241 rotatably connected to one end of the conveying platform 21, a driven roller 242 rotatably connected to the other end of the conveying platform 21, and a driving motor 243 fixed to the conveying platform 21. The output shaft of the driving motor 243 is connected to the active roller 241 to drive the active roller 241 to rotate. The conveyor belt 23 is wrapped around the active roller 241 and the driven roller 242. By starting the driving motor 243, the driving motor 243 will drive the active roller 241 to rotate, thereby driving the conveyor belt 23 to move on the conveying platform 21, and then driving the conveying block 22 to move, so as to realize the conveying of the pipe.

[0030] Among them, a plurality of conveying blocks 22 are arranged at intervals in the length direction of the conveyor belt 23, ensuring that a plurality of pipes can be sequentially conveyed to the feed port of the laser pipe cutting machine under the drive of the conveyor belt 23. And by controlling the operation of the driving motor 243, the conveying speed of the conveyor belt 23 can be accurately adjusted to meet different processing requirements.

[0031] Reference Figure 2 and Figure 3 In order to prevent the conveying block 22 from getting stuck due to the inability to bend when the conveying belt 23 drives the conveying block 22 to change direction during the conveying process of the conveying block 22 along the conveying belt 23, a mounting plate 25 is fixedly connected to the side of each conveying block 22 facing the conveying belt 23, and the side of the mounting plate 25 away from the conveying block 22 is fixedly connected to the conveying belt 23. The mounting plate 25 is made of soft material, so that when the conveying belt 23 drives the conveying block 22 to reach the turning point of the direction, the mounting plate 25 can bend synchronously with the conveying belt 23 at any time to ensure the normal conveying work of the conveying block 22.

[0032] In addition, in order to more accurately control the transmission distance of the pipe and ensure that each pipe can be transported to the feed port of the laser pipe cutting machine in sequence, an encoder can also be installed on the output shaft of the drive motor 243, and the encoder and the drive motor 243 are connected to the PLC controller. The encoder is used to collect the rotation amount of the output shaft of the drive motor 243 in real time, and transmit the collected data to the PLC controller. When the data received by the PLC controller reaches the set value, a stop command is output, and the drive motor 243 stops running after receiving the stop designation, thereby ensuring that a pipe is accurately transmitted to the predetermined position, and the next pipe waits for the laser pipe cutting machine to cut the pipe and then feed again. Therefore, when in use, it can be set that when the PLC controller outputs a stop command, the timer inside the PLC controller also starts timing, and when the timing reaches the set time, a start command is issued, and the drive motor 243 starts after receiving the start command, thereby delivering the next pipe to the laser pipe cutting machine, and circulates in sequence, so as to realize that the pipes are delivered to the laser pipe cutting machine one by one.

[0033] Reference Figure 2 and Figure 4 In order to enable the conveying platform 21 to adapt to the needs of laser tube cutting machines of different heights, the height of the conveying platform 21 can be adjusted so that the height of the conveying platform 21 can be adjusted as needed.

[0034] Specifically, the conveying platform 21 includes a mounting frame 211 and support legs 212 hinged at four corners of the mounting frame 211, and the driving member 24 is mounted at both ends of the mounting frame 211. The support leg 212 includes an upper rod 2121, a lower rod 2122, and an adjustment cylinder 2123 whose two ends are respectively threadedly connected between the upper rod 2121 and the lower rod 2122. The adjustment cylinder 2123 is internally processed with internal threads, and the internal threads at both ends of the adjustment cylinder 2123 are rotated in opposite directions, so that when the adjustment cylinder 2123 is rotated, the upper rod 2121 and the lower rod 2122 can be adjusted to be relatively close or away from each other, thereby realizing the adjustment of the height of the support leg 212 to meet the use needs of different occasions.

[0035] Reference Figure 2The placement box 1 includes mounting legs 11 and a box body 12. The upper end opening of the box body 12 is used for placing the pipes lifted by the overhead crane in the box body 12. The mounting legs 11 are firmly supported on the ground to ensure the stability of the box body 12. A discharge port 121 is provided on one side of the box body 12 for discharging the pipes. In order to better guide the discharging direction of the pipes, a guide plate 13 with a U-shaped cross-section can be fixed on one side of the discharge port 121, and the other end of the guide plate 13 abuts against the upper side of the conveying component 2 away from the laser cutting machine to ensure that the pipes can smoothly reach the conveying component 2 from the box body 12 along the guide plate 13. Among them, the U-shaped opening of the guide plate 13 faces upward to prevent the pipes from falling from both sides of the guide plate 13 during transportation. The guide plate 13 is tilted as a whole, and its height gradually decreases from one end close to the box body 12 to the end away from the box body 12, which can ensure that the pipe slides out of the discharge port 121 smoothly under the action of gravity and enters the conveying component 2 along a predetermined direction.

[0036] Furthermore, the guide plate 13 may also include a fixed plate 131 and a movable plate 132. The fixed plate 131 is fixedly connected to the box body 12, and the movable plate 132 is hinged to the side of the fixed plate 131 away from the box body 12, so that the side of the movable plate 132 away from the fixed plate 131 can always abut against the conveying assembly 2 under the action of gravity, thereby ensuring smooth conveying of the pipe.

[0037] In addition, in order to adjust the size of the discharge port 121 to accommodate pipes of different specifications, an adjustment plate 14 can be slidably connected to the side of the box body 12 facing the discharge port 121. The adjustment plate 14 is V-shaped as a whole, including a sliding portion 141 sliding on the box body 12 and a limiting portion 142 fixed to one end of the sliding portion 141. The limiting portion 142 is located on the upper side of the guide plate and surrounds the guide plate to form a closed space for the pipe to slide. The sliding portion 141 of the adjustment plate 14 can slide along the side of the box body 12, thereby changing the width of the discharge port 121. At the same time, a fixing member 15 is provided on the box body 12 to fix the position of the adjustment plate 14 on the box body 12.

[0038] Reference Figure 2 and Figure 5The fixing member 15 may include two L-plates 151 with openings facing each other and two fixing bolts 152 fixedly connected to the box body 12, and each fixing bolt 152 is threadedly connected with a fixing nut 153. The L-plates 151 are located on both sides of the box body 12, and an adjustment space for the sliding part 141 to slide is formed between the two L-plates 151. At the same time, a slide groove 143 is provided on the sliding part 141 for the two fixing bolts 152 to pass through and slide. The two slide grooves 143 are respectively located on both sides of the sliding part 141, and the fixing nut 153 is located on the side of the sliding part 141 away from the box body 12. When the sliding part 141 is operated to slide on the box body 12 to adjust the size of the discharge port 121, the two L-plates 151 fix the two sides of the sliding part 141 to prevent the two sides of the sliding part 141 from tilting. At the same time, the fixing bolt 152 also slides in the slide groove 143 . When the adjustment plate 14 is operated to slide to a suitable position, the fixing nut 153 is directly tightened to fix the adjustment plate 14 through the fixing nut 153 to ensure the stability of the discharge port 121 .

[0039] Reference Figure 1 Braking universal wheels 3 are installed at the lower ends of the supporting legs 212 and the mounting legs 11 to facilitate the movement of the box body 12 and the conveying assembly 2. When moved to a suitable position, the position of the auxiliary feeding device of the laser cutting machine can be fixed directly by the braking universal wheels 3.

[0040] The implementation principle of the auxiliary feeding device of the laser tube cutting machine in the embodiment of the present application is as follows: through the synergistic effect of the conveying platform 21 and the conveying block 22, the tube is smoothly and accurately conveyed from the placement box 1 to the feed port of the laser tube cutting machine. This auxiliary feeding device not only improves the feeding accuracy, but also reduces the labor intensity of the workers, providing strong support for the efficient and stable operation of the laser tube cutting machine.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
