[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-4The utility model provides a technical solution: a pipe cutting machine, including a feeding device 1, the feeding device 1 includes a plurality of feeding racks 10, the feeding racks 10 are connected in sequence side by side, and the adjacent feeding racks 10 are connected by a cross bar, each feeding rack 10 includes a first support column 102 and a second support column 103, a feeding trough 104 is formed between the first support column 102 and the second support column 103, a feeding belt 101 is provided on the feeding rack 10, the feeding belt 101 is in a relaxed state when not tightened and hangs in the feeding trough 104, and a feeding transmission is provided between the feeding racks 10. The feeding transmission rod 105 is rotatably connected with the feeding rack 10, and a winding shaft 106 is provided on the feeding transmission rod 105 corresponding to each feeding rack 10. The two ends of the feeding belt 101 are respectively fixedly connected with the top of the first support column 102 and the winding shaft 106. A rotating motor 108 is also provided on the cross bar. The feeding transmission rod 105 is transmission-connected with the rotating motor 108. The rotating motor 108 can drive the feeding transmission rod 105 to rotate, thereby driving the winding shaft 106 to rotate, and then the feeding belt 101 is wound on the winding shaft 106. The reel 106 tightens the feeding belt 101. At this time, the part of the feeding belt 101 hanging in the feeding trough 104 will gradually tighten and lift. Therefore, when the pipe needs to be fed and cut, first, several pipes are placed on the feeding belt 101 hanging in the feeding trough 104. Then the motor 108 is turned to drive the feeding transmission rod 105 to rotate. At this time, the feeding transmission rod 105 drives the winding shaft 106 to rotate synchronously. Since one end of the feeding belt 101 is fixedly connected to the winding shaft 106, the feeding belt 101 will be wound on the winding shaft 106 at this time. The other end of the belt 101 is fixedly connected to the top of the first support column 102, so as the reel 106 reels the feeding belt 101, the feeding belt 101 hanging in the feeding trough 104 will slowly tighten and thus be lifted. At this time, the pipe on the feeding belt 101 in the feeding trough 104 will also be lifted. Since the installation position of the reel 106 is lower than the top of the first support column 102, when the feeding belt 101 is tightened, the tightened feeding belt 101 will be in an inclined state, so the pipe on the feeding belt 101 will roll down to complete automatic loading.

[0025] The height of the first support column 102 is greater than that of the second support column 103, and a rotatably connected fixed pulley 107 is provided on the top of the second support column 103. When the two ends of the feeding belt 101 are respectively connected to the top of the first support column 102 and the winding shaft 106, the feeding belt 101 is also placed on the fixed pulley 107. By making the feeding belt 101 be placed on the fixed pulley 107 on the top of the second support column 103, when the pipe is placed on the hanging feeding belt 101 and the feeding belt 101 is wound and lifted, at this time, since the feeding belt 101 bears a heavier gravity, the fixed pulley 107 can assist the feeding belt 101 in migrating and winding during winding, thereby improving the lifting and feeding effect.

[0026] A blocking mechanism 12 is also provided on each loading rack 10, and the blocking mechanism 12 includes a connecting plate 120 fixedly connected to the second support column 103 and a first lifting cylinder 121 and a second lifting cylinder 122 respectively provided on the connecting plate 120, and the first lifting cylinder 121 and the second lifting cylinder 122 are respectively provided with a first blocking plate 123 and a second blocking plate 124 connected thereto in transmission. A pressing mechanism 11 is also provided on the loading rack 10, and the pressing mechanism 11 is used to feed the pipes one by one. The pressing mechanism 11 is located at both ends of the loading device 1, and the pressing mechanism 11 includes a lifting cylinder 110 and a lifting cylinder 110 connected in transmission to the lifting cylinder 110. The lifting plate 111 is connected to the lifting plate 111, and a pressing cylinder 112 and a pushing cylinder 113 are respectively provided on the lifting plate 111. The pressing cylinder 112 is provided with a pressing plate 114 connected thereto by transmission, and the pushing cylinder 113 is provided with a pushing plate 115 connected thereto by transmission. When the feeding belt 101 is tightened and lifted to make the pipe roll down from the feeding belt 101, since several pipes are concentrated on the feeding belt 101, if all the pipes roll down uniformly at this time, an accident may occur. Therefore, the lifting cylinder 110 drives the lifting plate 111 to descend at this time, so that the gap between the bottom of the lifting plate 111 and the top of the connecting plate 120 is reduced. Only the width that one pipe can roll down is reached, and then the pipes roll down one by one to between the lifting plate 111 and the connecting plate 120. At this time, the first lifting cylinder 121 drives the first baffle plate 123 to rise, so that the pipe is blocked by the first baffle plate 123, and the pushing cylinder 113 drives the pushing plate 115 to repeatedly push in the parallel direction to the top of the lifting plate 111, thereby pushing the remaining accumulated pipes back and forth onto the feeding belt 101, and then the first lifting cylinder 121 drives the first baffle plate 123 to descend, and the pipe continues to roll down, and the second lifting cylinder 122 drives the second baffle plate 124 to rise again, and the second baffle plate 124 again pushes the pipe Interception, at this time, several pipes are arranged one by one on the top of the connecting plate 120, when the second lifting cylinder 122 drives the second baffle plate 124 to descend, at this time, in order to ensure that the pipes can be rolled down and loaded one by one, the pressing cylinder 112 drives the pressing plate 114 to descend to press the second pipe at the rolling end, so that the front pipe that has not been pressed rolls down for loading, and the rear pipe cannot roll down at this time due to the obstruction of the pressed pipe, and as the pressing cylinder 112 drives the pressing plate 114 to rise and fall in sequence and press the rolled pipes in sequence, the pipes can be unloaded one by one from the feeding device 1.

[0027] The pipe cutting machine also includes a processing table 2, which is arranged on the side of the feeding device 1 close to the second support column 103. The processing table 2 is provided with a feeding and transporting mechanism 20, which includes a conveying chain 201. There are several placement stations on the conveying chain 201. Since the pipes are loaded one by one on the feeding device 1, when the pipes roll down, they will fall on the placement stations one by one for loading. A clamping and positioning device 21 is also provided at one end of the processing table 2. The clamping and positioning device 21 is in contact with the processing device 1. The tables 2 are slidably matched with each other. There is a slide rail on the processing table 2 for the clamping and positioning device 21 to slide. A cutting device 22 is also provided at the other end of the processing table 2. After the pipe is loaded onto the conveyor chain 201, the conveyor chain 201 continues to drive the pipe to the side of the clamping and positioning device 21, and then the clamping and positioning device 21 clamps and positions the pipe, and then the cutting device 22 is started to cut the pipe into segments. A laser head is provided in the cutting device 22, and the pipe cutting machine is mainly used for laser cutting.

[0028] The beneficial effects of the present invention are as follows: by providing a feeding belt 101 on the feeding rack 10, all the pipes that need to be fed and cut are first placed on the feeding belt 101. Then, when feeding is required, the feeding belt 101 is tightened and lifted by winding up the feeding belt 101, so that the pipes placed on the feeding belt 101 can be lifted and then rolled off the feeding belt 101 to realize automatic feeding. In addition, a pressing mechanism 11 is also provided on the feeding rack 10, and the pressing mechanism 11 presses the pipes to be fed, so that the pipes can be fed one by one, and the whole bundle of pipes is prevented from rolling off the feeding belt 101 for feeding, thereby improving the feeding effect.
