Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Next, according to Figure 1 one Figure 7 Describe the cutting device for large metal waste materials provided by the embodiments of the present utility model.

[0026] Please refer to Figure 1 and Figure 2, the present utility model discloses a cutting device for treating large metal scraps, including a cutting electric saw 5. When the cutting electric saw 5 is working, it is used to directly divide large metal scraps into small pieces. Here, there are at least two cutting electric saws 5, and the two cutting electric saws 5 are arranged side by side. Here, the side-by-side arrangement means side by side along the length direction of the large metal scrap. For example, in Figure 2 the shown state, the large metal scrap should be placed horizontally. At this time, multiple cutting electric saws 5 are located above the large metal scrap side by side. As shown in the figure, there are four cutting electric saws 5.

[0027] A cam lifting mechanism is also provided. The number of cam lifting mechanisms is the same as the number of cutting electric saws 5, and there are also at least two. One cam lifting mechanism drives a corresponding cutting electric saw 5 to press down for cutting, and the cam lifting mechanism should be located above the opposite cutting electric saw 5, and the adjacent two cam lifting mechanisms lift alternately so that the two cutting electric saws 5 cut alternately.

[0028] Since the adjacent two cutting electric saws 5 of the cutting device for treating large metal scraps provided by the embodiment of the present utility model are in an alternating cutting state, on the one hand, the pressure on the lifting mechanism can be greatly reduced, and the service life of the lifting mechanism can be prolonged. On the other hand, the efficiency of alternating cutting is higher than that of the single cutter head cutting and the conveying of metal scraps by the conveyor belt below in the prior art.

[0029] Combined with Figure 3 , Figure 4 , Figure 6 and Figure 7 shown, in order to ensure the stability of the workpiece (large metal scrap) during cutting, a stabilizing mechanism 7 is also provided here. The stabilizing mechanism 7 includes mounting platforms 73 on both sides of the cutting electric saw 5, a stabilizing frame 71 rotatably mounted on the side of the mounting platform 73 away from the cutting electric saw 5 through a central shaft 75, and a stabilizing wheel 72 mounted at the other end of the stabilizing frame 71. A torsion spring 76 is provided in the gap between the stabilizing frame 71 and the central shaft 75. When the torsion spring 76 is in a natural state, the height of the stabilizing wheel 72 is lower than the lower surface height of the cutting electric saw 5.

[0030] Preferably, a groove 74 is opened at a position on the mounting platform 73 opposite to the stabilizing frame 71. The central shaft 75 penetrates through the groove 74, and one end of the stabilizing frame 71 is located on the central shaft 75 within the groove 74.

[0031] In this embodiment, when the cutting electric saw 5 gradually descends, the stabilizing frame 71 also descends. The stabilizing wheel 72 first contacts the large piece of metal waste. As the cutting electric saw 5 gradually descends, the stabilizing frames 71 on both sides rotate on the corresponding central axes 75, increasing the angle between them. In this way, on the one hand, the stabilizing frame 71 can press the large piece of metal waste, playing a stabilizing role in cutting. On the other hand, the stabilizing frames 71 moving towards both sides can pull the large pieces of metal waste on both sides of the cut mark, accelerating the splitting of the metal waste.

[0032] Combined with Figure 1 and Figure 2 As shown, it also includes a frame 1 and a cutting table 4. The upper frame 1 is located at the upper rear side of the cutting table 4. The cam lifting mechanism is installed on the frame 1. The cutting electric saw 5 is located directly above the cutting table 4. Thus, when the cutting electric saw 5 moves downward, it can cut the large piece of metal waste on the upper surface of the cutting table 4.

[0033] As Figure 3 and Figure 5 As shown, the cutting electric saw 5 includes a bracket 51, a groove ring 54 opened on the outer edge of the bracket 51, sprockets provided at both ends inside the bracket 51, a chain 52 drivingly connected between the two sprockets, a saw blade 53 fixedly provided on the outer surface of the chain 52, and a motor 55 for driving one of the sprockets to rotate. The chain 52 is located inside the groove ring 54 so that the chain 52 does not contact the large piece of metal waste.

[0034] In this embodiment, when the motor 55 works, it can drive one of the sprockets to rotate. Subsequently, the chain 52 rotates inside the groove ring 54, driving the saw blade 53 to rotate and realizing the cutting operation of the saw blade 53.

[0035] As Figure 1 , Figure 2 and Figure 5 As shown, the above-mentioned cam lifting mechanism includes a cam 3, a mounting seat 6, and a return spring 9. The cam 3 is located above one end of the bracket 51 close to the frame 1, and the cam 3 is rotatably mounted on the frame 1 through a connecting shaft; one end of the bracket 51 is installed inside the mounting seat 6. The motor 55 is fixedly provided on one side of the mounting seat 6. A pressure rod 8 is installed on the upper surface of the mounting seat 6, and the upper end of the pressure rod 8 extends to the lower surface of the cam 3. A first pressing plate 10 is fixedly provided at the upper end of the pressure rod 8; the return spring 9, the return spring 9 is sleeved on the pressure rod 8, and the return spring 9 is located between the first pressing plate 10 and the lower side surface of the frame 1.

[0036] In this embodiment, the placement directions of two adjacent cams 3 should be opposite, so as to ensure that two adjacent cutting electric saws 5 cut alternately.

[0037] Further, when the cam 3 rotates and its far-axis side rotates to the position of the first pressing plate 10, it can press down the return spring 9 and the pressure rod 8, so that the pressure rod 8 can push down the cutting electric saw 5 to realize the cutting operation of the cutting electric saw 5. Conversely, when the far-axis side of the cam 3 gradually disengages from the first pressing plate 10, the spring 9 rebounds and lifts the cutting electric saw 5 through the pressure rod 8 to complete a cycle of cutting operation.

[0038] As Figure 1 and Figure 2 , in order to make all the cams 3 rotate synchronously, a driving structure 2 for driving the rotation of the cams 3 is also provided. The driving structure 2 includes a turbine 22 fixed to one end of the cam 3, a worm 21 meshed on one side of the turbine 22, and a motor 23 installed on the frame 1 for driving the rotation of the worm 21.

[0039] In this embodiment, the motor 23 can drive the worm 21 to rotate, and the worm 21 can drive all the cams 3 to rotate synchronously through the turbine 22.

[0040] As Figure 4 , an infrared distance sensor 14 is fixedly installed on the lower surface of the mounting seat 6, and a measured plate 101 is installed at a position opposite to the infrared distance sensor 14 below the frame 1. The infrared distance sensor 14 is used to detect the distance between the mounting seat 6 and the measured plate 101; it also includes a comparator and a controller. The comparator is used to compare the magnitudes of the detection values of the infrared distance sensor 14 within a unit time, and the controller is used to receive the signal from the comparator and control the operation or non-operation of the motor 55.

[0041] When the distance detected by the infrared distance sensor 14 compared by the comparator gradually decreases (i.e., when the cutting electric saw 5 gradually descends), the controller controls the motor 55 to turn on. Conversely, when the distance detected by the infrared distance sensor 14 compared by the comparator gradually increases (i.e., when the cutting electric saw 5 gradually ascends), the controller controls the motor 55 to turn off.

[0042] Working principle and usage process of the present utility model: During use, place the large metal waste to be cut on the upper surface of the cutting table 4, drive the motor 23, so that the motor 23 drives the worm 21 to rotate. The worm 21 can synchronously drive all the cams 3 to rotate through the turbine 22. When the cam 3 rotates and its far-axis side rotates to the position of the first pressing plate 10, it can press down the return spring 9 and the pressure rod 8, so that the pressure rod 8 can push the cutting electric saw 5 downward to realize the cutting operation of the cutting electric saw 5. On the contrary, when the far-axis side of the cam 3 gradually disengages from the first pressing plate 10, the spring 9 rebounds, and the cutting electric saw 5 is lifted through the pressure rod 8 to realize a cycle of cutting operation. Since two adjacent cutting electric saws 5 are in an alternating cutting state, on the one hand, the pressure on the lifting mechanism can be greatly reduced, and the service life of the lifting mechanism can be prolonged. On the other hand, the efficiency of alternating cutting is higher than that of a single cutting head cutting and conveying metal waste by a conveyor belt below in the prior art.

[0043] It should be noted that in this article, terms such as "including", "comprising" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or further includes elements inherent to such process, method, article or device. Without more limitations, an element defined by the statement "including a..." does not exclude the existence of another identical element in the process, method, article or device including the said element.

[0044] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
