[0041] As Figures 1 to 8 shown, this embodiment provides a catheter punching device, including a machine body 1 and the following components arranged on the machine body 1:

[0042] A positioning seat 2 for fixing the catheter;

[0043] A punching assembly 3, including a first driving member 31 and a punching knife 32. The punching knife 32 is configured to be driven by the first driving member 31 to approach or move away from the positioning seat 2, and punch the catheter located on the positioning seat 2 during the process of approaching the positioning seat 2; wherein, the punching knife 32 has a hollow structure, so the waste generated by punching will accumulate inside the punching knife 32;

[0044] A material discharging assembly 4, including a material discharging rod 41. The material discharging rod 41 is located inside the punching knife 32, and the material discharging rod 41 can generate relative displacement with the punching knife 32 to discharge the waste located inside the punching knife 32;

[0045] The blowing assembly 5 includes a gas generating device (not shown in the figure) and a blowing pipeline 51. The first end of the blowing pipeline 51 is connected to the gas generating device, and the second end 511 of the blowing pipeline faces the punching knife 32;

[0046] The vacuum assembly 6 includes a vacuum generating device 61 and a vacuum pipeline 62. The first end of the vacuum pipeline is connected to the vacuum generating device 6, and the second end 621 of the vacuum pipeline faces the punching knife 32.

[0047] Wherein, the second end 511 of the blowing pipeline facing the punching knife 32 means that when the punching knife 32 is in the non-punched state, the second end 511 of the blowing pipeline faces the punching knife 32. Specifically, when the punching knife 32 is in the non-punched state, the second end 511 of the blowing pipeline faces the punching end of the punching knife 32, that is, the end of the punching knife 32 away from the first driving member 31.

[0048] Wherein, the second end 621 of the vacuum pipeline facing the punching knife 32 means that when the punching knife 32 is in the non-punched state, the second end 621 of the vacuum pipeline faces the punching knife 32. Specifically, when the punching knife 32 is in the non-punched state, the second end 621 of the vacuum pipeline faces the punching end of the punching knife 32, that is, the end of the punching knife 32 away from the first driving member 31.

[0049] In this embodiment, by setting the blowing assembly 5, the waste inside the punching knife 32 discharged when the discharging rod 41 and the punching knife 32 generate relative displacement is blown off, avoiding the waste from sticking to the punching end of the punching knife 32 and ensuring that the waste is separated from the punching knife 32; and a negative pressure is generated at the punching knife 32 through the vacuum assembly 6 to collect the blown-off waste.

[0050] This embodiment has a high degree of automation, reduces the time for manual waste cleaning, improves the overall efficiency of the catheter punching device, and reduces the labor cost; and has strong continuous operation ability, can ensure that the waste is removed in time and effectively, and avoid the interruption of the production process caused by waste accumulation.

[0051] As Figure 2 shown, in one embodiment, the second end 511 of the blowing pipeline and the second end 621 of the vacuum pipeline are respectively located on both sides of the punching knife 32. Specifically, when the punching knife 32 is in the non-punched state, the second end 511 of the blowing pipeline and the second end 621 of the vacuum pipeline are respectively located on both sides of the punching knife 32.

[0052] Specifically, when the punching knife 32 is in the non-punched state, the second end 511 of the blowing pipeline and the second end 621 of the vacuum pipeline are respectively located on both sides of the punching end of the punching knife 32, that is, when the punching knife 32 is in the non-punched state, the second end 511 of the blowing pipeline and the second end 621 of the vacuum pipeline are respectively located on both sides of the end of the punching knife 32 away from the first driving member 31.

[0053] In this embodiment, by arranging the second end 511 of the air blowing pipe and the second end 621 of the vacuum pipe on both sides of the punching knife 32 respectively, the gas output from the second end 511 of the air blowing pipe applies a force in the direction close to the second end 621 of the vacuum pipe to the waste discharged from the inside of the punching knife 32, so that the waste discharged from the inside of the punching knife 32 moves towards the second end 621 of the vacuum pipe, thereby improving the collection effect of the vacuum assembly 6 on the waste and ensuring that the waste is effectively removed.

[0054] As Figure 5 and Figure 6 shown, in one embodiment, the punching assembly 3 further includes a punching knife holder 33, the punching knife 32 is arranged on the punching knife holder 33, and the first driving member 31 drives the punching knife 32 through the punching knife holder 33.

[0056] As Figure 5 and Figure 6 shown, in one embodiment, the discharging assembly 4 further includes a second driving member 42, the second driving member 42 is arranged on the punching knife holder 33, and the discharging rod 41 is configured to be driven by the second driving member 42 to move inside the punching knife 32. In this embodiment, by arranging the second driving member 42 to drive the discharging rod 41 to move inside the punching knife 32, a relative displacement is generated between the discharging rod 41 and the punching knife 32, and the waste inside the punching knife 32 is pushed out of the punching knife 32. Automatic discharging is realized, the time of manual discharging is reduced, and it helps to improve the overall efficiency of the catheter punching device.

[0057] Specifically, the second driving member 42 is a cylinder, but is not limited thereto.

[0058] In another embodiment, one end of the discharging rod 41 is arranged on the machine body 1, and the other end extends into the inside of the punching knife 32. When the punching knife 32 is in the non-punching state, the end of the discharging rod 41 far from the machine body 1 extends into the inside of the punching knife 32 and then exposes out of the punching knife 32 through the punching end of the punching knife 32; when the punching knife 32 is in the punching state, the first driving member 31 drives the punching knife 32 to approach the positioning seat 1, a relative movement is generated between the punching knife 32 and the discharging rod 41, and the end of the discharging rod 41 far from the machine body 1 is located inside the punching knife 32; when the first driving member 31 drives the punching knife 32 to reset, the end of the discharging rod 41 far from the machine body 1 exposes out of the punching knife 32 through the punching end of the punching knife 32 and pushes the waste inside the punching knife 32 out of the punching knife 32.

[0059] This embodiment realizes automatic discharging, reduces the time of manual discharging, and helps to improve the overall efficiency of the catheter punching device.

[0068] Specifically, the identification body 232 is in a regular polygonal shape.

[0069] Such as Figure 3 and Figure 4As shown, in one embodiment, the positioning seat 2 includes a positioning base 21, a strip-shaped positioning block 25 and a strip-shaped guide rail 24 located on the positioning base 21.
