[0036] See also Figure 2 and Figure 3 , Figure 2 is a structural schematic diagram of the first embodiment of the pipe cutting mechanism of the present application, Figure 3 The pipe cutting mechanism 1 provided in the embodiment of the present application comprises a cutting assembly 11 and a cutting fixture 12 .

[0037] The cutting fixture 12 has an accommodating space for placing the pipe. The cutting assembly 11 is spaced apart from the cutting fixture 12 and is used to cut the pipe in the accommodating space.

[0038] The cutting fixture 12 has a plurality of cutting grooves 121 on one side close to the cutting assembly 11, and the extending direction of the cutting grooves 121 is perpendicular to the extending direction of the pipe in the accommodating space. After the pipe is placed in the accommodating space, the cutting assembly 11 enters the accommodating space through the cutting grooves 121 to cut the pipe in the accommodating space.

[0039] Since the cutting fixture 12 includes a plurality of cutting grooves 121 , the cutting fixture 12 can perform multi-section cutting on the pipe located in the cutting fixture 12 at one time, thereby improving the cutting efficiency of the pipe cutting mechanism 1 on the pipe.

[0040] Optionally, the distance between any two adjacent cutting grooves 121 is equal to a preset length of the pipe cutting.

[0041] Specifically, if the tube needs to be cut into a length of 10 mm, the distance between any two adjacent cutting grooves 121 is 10 mm. Therefore, when the cutting assembly 11 enters the accommodating space through the cutting groove 121 to cut the tube, the tube can be directly cut into the required length without the need for secondary processing, and the generation of waste is reduced, thereby improving the efficiency of the tube cutting mechanism 1 in cutting the tube and improving the practicality of the tube cutting mechanism 1.

[0042] In another embodiment, when the distance between any two adjacent cutting grooves 121 on the cutting fixture 12 is equal to the preset distance length of the pipe cutting, the specific distance between any two adjacent cutting grooves 121 of the present application is not limited.

[0043] Optionally, see Figure 2 The cutting assembly 11 includes three rotating rollers 111 and a cutting line 112 .

[0044] The distance between any two of the three rotating rollers 111 is equal, and the cutting line 112 is wound around the three rotating rollers 111 in sequence, and the cutting line 112 surrounds the three rotating rollers 111 to form an isosceles triangle.

[0045] The cutting line 112 between the two rotating rollers 111 enters the accommodation space of the cutting fixture 12 to cut the pipe in the accommodation space.

[0046] Specifically, since the cutting line 112 is wound around the rotating rollers 111, any two rotating rollers 111 support the cutting line 112, and the cutting line 112 is straightened. Then, the rotating rollers 111 drive the cutting line 112 to move close to the cutting fixture 12, and the straightened cutting line 112 between the two rotating rollers 111 is driven to pass through the cutting groove 121 into the accommodating space, and the pipe located in the accommodating space is cut. Among them, the cutting groove 121 can be a strip groove to allow the cutting line 112 to pass through.

[0047] Optionally, the width of the cutting groove 121 is equal to the diameter of the cutting line 112 , so that the cutting line 112 can enter the accommodating space through the cutting groove 121 to cut the pipe located in the accommodating space.

[0048] In one embodiment, the cutting wire 112 may be a diamond cutting wire (hereinafter referred to as diamond wire) to achieve cutting of the pipe. The diameter of the diamond wire in this embodiment is 0.2 mm, and the width of the cutting groove 121 may be 0.2 mm to allow the cutting wire 112 to pass through. In other embodiments, the width of the cutting groove 121 may be slightly larger than the diameter of the cutting wire 112 to further ensure that the cutting wire 112 can pass through the cutting groove 121 and enter the accommodating space.

[0049] Furthermore, the number of turns of the cutting line 112 around the rotating roller 111 can correspond to the number of cutting grooves 121 on the cutting fixture 12, and the distance between any two adjacent cutting lines 112 is equal to the distance between any two adjacent cutting grooves 121, and then in the process of the rotating roller 111 driving the cutting line 112 to move close to the cutting fixture 12, each cutting line 112 can enter the accommodating space of the cutting fixture 12 through the corresponding cutting groove 121 to cut the pipe located in the accommodating space. As can be seen from the foregoing, the distance between any two adjacent cutting grooves 121 is equal to the preset length of the pipe cutting, therefore, any two adjacent cutting lines 112 can cut a pipe of a preset length, meet the needs of users, and improve the practicality of the pipe cutting mechanism 1.

[0050] Optionally, the body of the rotating roller 111 includes a winding area 113 .

[0051] The winding area 113 includes a plurality of grooves (not shown), and the cutting wire 112 is wound on the winding area 113 of the rotating roller 111 and is located in the grooves. The cutting wire 112 is fixed to the rotating roller 111 to prevent the cutting wire 112 from moving relative to the rod body of the rotating roller 111 during the cutting operation driven by the rotating roller 111, thereby affecting the cutting effect on the pipe. In this embodiment, the cutting wire 112 is fixed to the groove by setting the groove on the rod body of the rotating roller 111, thereby improving the stability of the cutting wire 112 on the rotating roller 111 and improving the stability of the pipe cutting mechanism 1.

[0052] Further, the length of the winding area 113 is equal to the length of the cutting fixture 12 .

[0053] The length of the cutting fixture 12 can be the original length of the pipe. For example, if a 600mm pipe needs to be cut, the length of the cutting fixture 12 can be 600mm to accommodate the pipe. The length of the winding area 113 can also be 600mm, and the cutting wire 112 is wound on the winding area 113 to cover the entire length of the cutting fixture 12, so that the pipe in the cutting fixture 12 can be cut at one time, thereby improving the cutting efficiency of the pipe cutting mechanism 1.

[0054] Optionally, see Figure 4 , Figure 4 The cutting fixture 12 also includes a base 122 and a cover plate 123 .

[0055] The base 122 includes a bottom plate 1221 and a support plate 1222. The support plate 1222 is disposed on the bottom plate 1221, and the cross-section of the support plate 1222 is U-shaped to accommodate the pipe 2. The cover plate 123 is covered on the base 122, and the cover plate 123 and the base 122 form an accommodating space.

[0056] Optionally, see Figure 3 and Figure 4 The cover plate 123 includes a plurality of first cutting grooves 1231, and the support plate 1222 includes a plurality of second cutting grooves 12221. The first cutting grooves 1231 and the second cutting grooves 12221 are arranged correspondingly. The cutting assembly 11 enters the accommodating space through the first cutting grooves 1231 and the second cutting grooves 12221 to cut the pipe 2 located in the accommodating space.

[0057] Specifically, the user may place the pipe 2 on the base 122, and cover the cover plate 123 on the base 122 to fix the pipe 2, and then the cutting assembly 11 is close to the cutting fixture 12, and the cutting line 112 enters the accommodating space through the first cutting groove 1231 and the second cutting groove 12221 to cut the pipe 2. Figure 3 As shown, the second cutting groove 12221 can be extended to the side wall and the bottom of the support plate 1222 to ensure that all the pipes 2 in the accommodating space are cut, thereby improving the cutting efficiency of the pipe cutting mechanism 1.

[0058] After the cutting assembly 11 has finished cutting the pipe 2 and the cutting assembly 11 is away from the cutting fixture 12, the user can separate the cover plate 123 from the base 122. The cut pipe 2 is stored on the base 122, and the user can further cut the pipe on the base 122, which improves the convenience of cutting the pipe. It also avoids the current situation in which the pipe to be cut is placed in the fixture, and the cut pipe is pushed out of the fixture to cut the pipe, so that the friction between the pipe and the fixture causes scratches on the surface of the pipe or the fixture. The safety of the pipe cutting mechanism 1 and the safety of the pipe 2 in the cutting fixture 12 are improved, and the user experience of the pipe cutting mechanism 1 is improved.

[0059] Alternatively, if Figure 4 As shown, the support plate 1222 includes two first side plates 12222, and the two first side plates 12222 are arranged in parallel.

[0060] The cross-sectional shape of the cover plate 123 is an inverted U-shape, including two second side plates 1232, and the two second side plates 1232 are arranged in parallel. The first side plate 12222 and the second side plate 1232 are fitted so that the cover plate 123 is covered on the base 122, and the cover plate 123 and the base 122 form a accommodating space.

[0061] Furthermore, the distance between the opposite sides of the two second side panels 1232 is greater than or equal to the distance between the opposite sides of the two first side panels 12222. The distance between the opposite sides of the two second side panels 1232 can be equal to the distance between the opposite sides of the two first side panels 12222, so as to ensure that when the cover plate 123 is covered on the base 122, it can be tightly connected with the base 122 to fix the pipe 2 located in the accommodating space. Or the distance between the opposite sides of the two second side panels 1232 can be slightly greater than the distance between the opposite sides of the two first side panels 12222, so as to facilitate the cover plate 123 to be covered on the base 122 or to separate the cover plate 123 from the base 122, simplify the difficulty of the user to connect the cover plate 123 and the base 122, and improve the user's experience of using the pipe cutting mechanism 1.

[0062] In summary, in the pipe cutting mechanism 1, the cutting component 11 includes a rotating roller 111 and a cutting wire 112 wound on the rotating roller 111, and the cutting fixture 12 includes a plurality of cutting grooves 121 on the side close to the cutting component 11. The rotating roller 111 drives the cutting wire 112 to enter the accommodating space through the plurality of cutting grooves 121 to cut the pipe 2 located in the accommodating space. The cutting component 11 cuts the pipe 2 in the cutting fixture 12 at one time, thereby improving the cutting efficiency of the pipe cutting mechanism 1 on the pipe 2.

[0063] The present application also provides a pipe cutting device (not shown), comprising a pipe cutting mechanism 1, wherein the pipe cutting mechanism 1 is used to cut the pipe to be cut.

[0064] The pipe cutting device may include a blanking component for storing the pipes after being cut by the pipe cutting mechanism 1 .
