[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the implementation scope of the present invention is not limited thereto.

[0033] like Figures 1 to 10 As shown, a copper tube cutting machine with high cutting efficiency described in this embodiment includes a cutting seat 1 and a cutting support 2 fixedly installed at one end of the cutting seat 1, a first turntable 3 is rotatably connected to the middle of the cutting support 2, and cutting mechanisms are slidably installed on both sides of the cutting support 2; a second turntable 5 coaxially connected to the first turntable 3 is rotatably installed at the other end of the cutting seat 1; two groups of material troughs 10 are symmetrically arranged on the outer peripheral walls of the first turntable 3 and the second turntable 5, and each group of material troughs 10 includes a plurality of material troughs 10 arranged at intervals;

[0034] The cutting support 2 is provided with a first transmission component and a second transmission component that is transmission-connected to the first transmission component, the first transmission component is transmission-connected to the first turntable 3, and the second transmission component is transmission-connected to the cutting mechanism; a driving mechanism 8 is provided at one end of the cutting seat 1, and the driving mechanism 8 is transmission-connected to the first transmission component, and a protective component is installed at the other end of the cutting seat 1, and the protective component can cover the outer peripheral walls of the first turntable 3 and the second turntable 5.

[0035] Specifically, when the driving mechanism 8 drives the first turntable 3 to rotate in the first direction through the first transmission assembly, the cutting mechanism remains stationary, and the driving mechanism 8 drives the first turntable 3 to rotate in the second direction through the first transmission assembly, and when the first turntable 3 rotates 270 degrees in the second direction, the driving mechanism 8 drives the two cutting mechanisms to move toward each other through the first transmission assembly and the second transmission assembly. In this embodiment, the first direction is clockwise, and the second direction is counterclockwise. In this embodiment, a feeding track 11 with a funnel-shaped cross section is provided on the top of the cutting seat 1. The first turntable 3 and the second turntable 5 are connected by a linkage shaft 20 to achieve synchronous linkage of the first turntable 3 and the second turntable 5.

[0036] When the copper tube cutting machine of this embodiment is actually used, the driving mechanism 8 drives the first turntable 3 to rotate in the clockwise direction through the first transmission component, and the first turntable 3 drives the second turntable 5 to rotate, and the protective component is covered on the outer peripheral wall of the first turntable 3 and the second turntable 5, and the copper tube to be cut is placed on the unloading track 11, and the copper tube to be cut falls along the unloading track 11. When the material troughs 10 of the first turntable 3 and the second turntable 5 correspond to the unloading port of the unloading track 11, the two ends of the copper tube to be cut are respectively inserted into the material troughs 10 of the first turntable 3 and the material troughs 10 of the second turntable 5. As the first turntable 3 and the second turntable 5 rotate 360 ​​degrees clockwise, the material troughs 10 on the first turntable 3 and the second turntable 5 are both inserted into the copper tube to be cut, and the feeding process of the copper tube to be cut is completed at this time;

[0037] Then the driving mechanism 8 drives the first rotating disk 3 and the second rotating disk 5 to rotate counterclockwise. After the first rotating disk 3 and the second rotating disk 5 rotate counterclockwise by 270 degrees, the driving mechanism 8 drives the two cutting mechanisms to move toward each other through the first transmission assembly and the second transmission assembly. During the movement of the two cutting mechanisms toward each other, the copper tubes to be cut on the two groups of material troughs 10 are cut respectively. When the first rotating disk 3 and the second rotating disk 5 rotate counterclockwise by 360 degrees, the two cutting mechanisms complete the cutting work of the copper tubes to be cut.

[0038] Then the two cutting mechanisms move away from each other, the protective assembly releases the outer peripheral wall of the first turntable 3 and the second turntable 5, and then the driving mechanism 8 drives the first turntable 3 and the second turntable 5 to rotate 360 ​​degrees clockwise. At this time, the cut copper tubes in each material trough 10 are detached from the material trough 10, thereby realizing the unloading process of the copper tubes.

[0039] In this embodiment, the driving mechanism 8 cooperates with the first transmission assembly and the second transmission assembly, and the protective assembly cooperates with the first turntable 3 and the second turntable 5, so that the copper tube loading is completed when the first turntable 3 and the second turntable 5 rotate along the first direction, and the cutting of multiple copper tubes is automatically completed when the first turntable 3 and the second turntable 5 rotate along the second direction, thereby improving the cutting efficiency of the copper tube, mechanizing the operation, reducing the safety risks of cutting, and improving product consistency.

[0040] This embodiment provides a material trough 10 on the first turntable 3 and the second turntable 5, and covers the outer peripheral walls of the first turntable 3 and the second turntable 5 with a protective component, so as to adapt to the cutting work of small-diameter copper tubes.

[0041] like Figures 2 to 6 As shown, a copper tube cutting machine with high cutting efficiency described in this embodiment, in some embodiments, the first transmission assembly includes a driving sleeve 61 fixedly installed in the first turntable 3, a driving rod 62 slidingly passing through the cutting support 2, and a driving disk 63 rotatably sleeved on one end of the driving rod 62, a spiral groove 611 is provided on the inner wall of the driving sleeve 61, a bayonet 621 is protruding from the other end of the driving rod 62, the bayonet 621 is movably embedded in the spiral groove 611, and the driving disk 63 is rotatably sleeved on the output end of the driving mechanism 8.

[0042] Specifically, the driving mechanism 8 is a cylinder structure. The driving mechanism 8 pushes the driving rod 62 to move through the driving disk 63. With the cooperation of the pin 621 and the spiral groove 611, the driving sleeve 61 drives the first turntable 3 to rotate in the clockwise direction, thereby realizing the loading and unloading of the copper tube; after the loading is completed, the driving mechanism 8 drives the driving rod 62 to move in the opposite direction through the driving disk 63, and the pin 621 moves in the opposite direction along the spiral groove 611, so that the driving sleeve 61 drives the first turntable 3 to rotate counterclockwise to cut the copper tube.

[0043] For example, Figure 8 As shown, one end of the spiral groove 611 close to the driving disk 63 penetrates the driving sleeve 61 to facilitate assembly between the driving rod 62 and the driving sleeve 61 .

[0044] like Figures 1 to 7As shown, a copper tube cutting machine with high cutting efficiency described in this embodiment, in some embodiments, the second transmission assembly includes an elliptical disk 71 rotatably connected to the cutting support 2, a first transmission rod 72 slidingly passing through the elliptical disk 71, an arc groove 73 arranged on the disk surface of the first rotating disk 3, and a torsion spring 74 connected between the elliptical disk 71 and the cutting support 2; an elliptical groove 711 is arranged on the side of the elliptical disk 71 facing away from the driving mechanism 8; a transition inclined surface 731 is arranged at one end of the arc groove 73, and the central angle of the arc groove 73 is 270 degrees; the cutting support 2 is provided with an arc hole to 2 When the first rotating disk 3 rotates, the first transmission rod 72 is avoided, and the central angle of the arc hole is 90 degrees; a guide cylinder 631 is arranged on the surface of the driving disk 63; one end of the first transmission rod 72 movably passes through the arc hole and then slides into the guide cylinder 631 and is connected with the driving disk 63 by a first spring 75; the cutting mechanism is provided with a second transmission rod 45, and the second transmission rod 45 is movably embedded in the elliptical groove 711; the other end of the first transmission rod 72 movably abuts on the surface of the first rotating disk 3, and the distance between the abutment point of the first transmission rod 72 and the first rotating disk 3 and the center of the first rotating disk 3 is equal to the radius of the arc groove 73. Initially, the two second transmission rods 45 are located at both ends of the long axis of the elliptical groove 711.

[0045] Specifically, when the first rotating disk 3 rotates clockwise, the first transmission rod 72 moves relative to the first rotating disk 3 along the circular trajectory of the arc groove 73. As the first rotating disk 3 rotates, the first transmission rod 72 is movably inserted into the arc groove 73 from the other end of the arc groove 73, and moves relatively along the trajectory of the arc groove 73, and then moves out of the arc groove 73 from one end of the arc groove 73 through the transition inclined surface 731. At this time, there is no power transmission between the first rotating disk 3 and the first transmission rod 72, so that the elliptical disk 71 does not rotate, that is, the two cutting mechanisms remain stationary. During the clockwise rotation of the first rotating disk 3, the first spring 75 keeps the first transmission rod 72 in contact with the first rotating disk 3.

[0046] When the first turntable 3 rotates counterclockwise, the first transmission rod 72 can slide into the arc groove 73 through the transition slope 731 and move along the trajectory of the arc groove 73 until the first transmission rod 72 abuts against the other end of the arc groove 73. At this time, the first transmission rod 72 and the first turntable 3 are rigidly connected to realize power transmission. The first turntable 3 pushes the elliptical disk 71 to rotate counterclockwise synchronously through the first transmission rod 72. The elliptical disk 71 drives the two second transmission rods 45 to move along the trajectory of the elliptical groove 711 through the elliptical groove 711, and move from the major axis of the elliptical groove 711 to the minor axis of the elliptical groove 711, thereby driving the two cutting mechanisms to move toward each other to cut the copper tube to be cut.

[0047] In some embodiments of the copper tube cutting machine with high cutting efficiency described in this embodiment, the driving rod 62 is connected to the cutting support 2. Through the above arrangement, the rotational freedom of the driving rod 62 is limited, ensuring that the driving rod 62 can reliably drive the first rotating disk 3 to rotate through the bayonet 621 and the spiral groove 611.

[0048] like Figures 1 to 3 , Fig. 9 As shown, a copper tube cutting machine with high cutting efficiency described in this embodiment, in some embodiments, the protection component includes a push plate 91 slidably connected to the cutting seat 1, a second spring 92 connected between the push plate 91 and the cutting seat 1 and two protection sliders 93 slidably connected to the cutting seat 1 in opposite directions; a third spring 94 is connected between the protection slider 93 and the cutting seat 1; both ends of the push plate 91 are provided with a first inclined surface 911, and the anti-slip slider is provided with a second inclined surface 931 for wedge-shaped cooperation with the first inclined surface 911; the protection slider 93 is also provided with a first arc baffle 932 that can be abutted against the outer peripheral wall of the second turntable 5; the bottom of the two first arc baffles 932 are provided with a U-shaped connecting rod 933, one end of the U-shaped connecting rod is connected to the first arc baffle 932, and the other end of the U-shaped connecting rod 933 is connected to the second arc baffle 934 that can be abutted against the outer peripheral wall of the first turntable 3.

[0049] Specifically, when loading is required, the two protective sliders 93 move toward each other under the elastic force of the third spring 94 until the first arc baffle 932 covers the outer peripheral wall of the second turntable 5, and the first arc baffle 932 drives the second arc baffle 934 to move toward each other through the U-shaped connecting rod 933, and the second arc baffle 934 covers the outer peripheral wall of the first turntable 3, and then the first turntable 3 and the second turntable 5 rotate 360 ​​degrees clockwise, thereby completing the copper tube loading;

[0050] When the first turntable 3 and the second turntable 5 rotate counterclockwise, the first arc baffle 932 remains covered on the outer peripheral wall of the second turntable 5, and the second arc baffle 934 remains covered on the outer peripheral wall of the first turntable 3, so as to keep the position of the copper tube to be cut fixed until the copper tube is cut;

[0051] When the cutting is completed and the material needs to be unloaded, the push plate 91 overcomes the elastic force of the second spring 92 and moves relative to the cutting seat 1. The two first inclined surfaces 911 of the push plate 91 respectively cooperate with the second inclined surface 931 of the protective slide 93 in a wedge shape, so that the two protective slides 93 each overcome the elastic force of the third spring 94 and move away from each other, so that the first arc baffle 932 and the second arc baffle 934 are separated from the covering of the second turntable 5 and the first turntable 3. At this time, the driving mechanism 8 causes the driving rod 62 to slide, and the driving rod 62 cooperates with the spiral groove 611 and the bayonet 621 to make the first turntable 3 rotate clockwise. When the material trough 10 rotates to the groove mouth downward, the copper tube in the material trough 10 moves out of the material trough 10 under its own weight, thereby completing the unloading of the copper tube.

[0052] like Figure 2 and Figure 3 As shown, in the present embodiment, a copper tube cutting machine with high cutting efficiency is described. In some embodiments, when the two first arc baffles 932 are against the outer peripheral wall of the second turntable 5 and the two second arc baffles 934 are against the outer peripheral wall of the first turntable 3, the tops of the two first arc baffles 932 and the tops of the two second arc baffles 934 are both formed with feeding notches, the bottoms of the two first arc baffles 932 are against each other, and the bottoms of the two second arc baffles 934 are against each other. Through the above arrangement, when the two first arc baffles 932 are against the outer peripheral wall of the second turntable 5 and the two second arc baffles 934 are against the outer peripheral wall of the first turntable 3, the copper tube to be cut in the unloading track 11 can enter the material trough 10 through the feeding notch, thereby realizing automatic feeding of the copper tube.

[0053] like Figure 2 , Figure 3 and Fig. 9 As shown, in some embodiments of the copper tube cutting machine with high cutting efficiency described in this embodiment, the two inner side walls of the cutting support 2 are respectively provided with guide tubes corresponding to the two protection slide blocks 93, and the protection slide block 93 is provided with a guide column 935, which is slidably inserted into the guide tube, and the third spring 94 is sleeved on the outer wall of the guide tube. In this embodiment, by providing the guide tube and the guide column 935, the movement of the protection slide block 93 is more stable, and the installation of the third spring 94 is also convenient.

[0054] like Figure 2 and Figure 3As shown, a copper tube cutting machine with high cutting efficiency described in this embodiment, in some embodiments, the cutting support 2 is provided with a mounting boss 21, and the cutting mechanism includes a first seat body 41 arranged on the mounting boss 21, a second seat body 42 slidably arranged on the first seat body 41, a cutting motor 43 arranged on the second seat body 42 and a disc saw blade 44 connected to the output end of the cutting motor 43; one end of the second transmission rod 45 is slidably inserted into the second seat body 42, a fourth spring 46 is connected between one end of the second transmission rod 45 and the second seat body 42, and the other end of the second transmission rod 45 is movably embedded in the elliptical groove 711.

[0055] Specifically, when the first turntable 3 drives the elliptical disk 71 to rotate synchronously counterclockwise through the first transmission rod 72, the elliptical disk 71 cooperates with the second transmission rod 45 through the elliptical groove 711 to synchronously drive the two second seat bodies 42 to move toward each other, and the second seat body 42 drives the cutting motor 43 to move. At the same time, the cutting motor 43 drives the disk saw blade 44 to rotate, thereby cutting the copper tubes to be cut on the first turntable 3 and the second turntable 5. During use, the fourth spring 46 keeps the second transmission rod 45 in cooperation with the elliptical groove 711.

[0056] In the copper tube cutting machine with high cutting efficiency described in this embodiment, in some embodiments, the first base body 41 is provided with a strip sliding hole, and the second base body 42 is provided with a sliding pin, and the sliding pin is movably embedded in the strip sliding hole. In this embodiment, the strip sliding hole and the sliding pin are provided to cooperate so that the second base body 42 drives the disc saw blade 44 to move more stably, so as to reliably cut the copper tube to be cut.

[0057] In some embodiments of the copper tube cutting machine with high cutting efficiency described in this embodiment, through holes for avoiding the disc saw blade 44 are provided on both side walls of the cutting seat 1. In some embodiments of the copper tube cutting machine with high cutting efficiency described in this embodiment, the mounting boss 21 is provided with an adjustment groove, the end of the first seat body 41 is movably arranged in the adjustment groove, and an adjustment block for limiting the first seat body 41 is arranged in the adjustment groove; in this way, by setting different adjustment blocks, the cutting length can be adjusted, and the structural flexibility is stronger.

[0058] The above is only a preferred embodiment of the present invention. Therefore, any equivalent changes or modifications made according to the structure, characteristics and principles described in the scope of the patent application of the present invention are included in the protection scope of the patent application of the present invention.
