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] A wire harness cutting machine, such as Figures 1-4 As shown, it includes a machine base 1, and a feeding assembly and a punching assembly are fixedly connected to the upper end of the machine base 1. The feeding assembly and the punching assembly cooperate with each other. The punching assembly includes a base 6, which is fixed to the upper end of the machine base 1, and a support seat 7 is fixedly connected to the upper end of the base 6. The punching seat 8 is fixedly connected to the upper end of the support seat 7, and a top seat 10 is fixedly connected to the upper end of the base 6. The pin material strip is wound on the feeding assembly, and the feeding assembly feeds the punching assembly.

[0025] The upper end of the top seat 10 is fixedly connected to a punching cylinder 11, and the output end of the punching cylinder 11 is fixedly connected to a punching knife seat 12 for punching the upper end of the punching seat 8. Two groups of electric winding drums 14 are rotatably connected inside the support seat 7. A discharge port 17 is opened at the upper end of the base 6, and the discharge port 17 is located below one end of the punching seat 8. Two groups of guide plates 18 are symmetrically arranged on the upper end of the discharge port 17, and a blowing component and a collecting component are respectively clamped on one side of the two groups of guide plates 18.

[0026] The material strip passes through the upper end of the punching seat 8, and the punching cylinder 11 drives the punching knife seat 12 to punch the material roll. The punched pins fall into the discharge port 17 along with the punching seat 8. The blowing component and the air collecting component cooperate to absorb the debris that is about to reach the discharge port 17, preventing the debris from entering the discharge port 17 along with the pins, and preventing the debris from affecting the punching quality of the pins. The waste after punching the pins is collected by an electric hand reel.

[0027] like Figure 1 As shown, the middle of the punching seat 8 is fixedly connected to the transmission seat 9, the length of the punching knife seat 12 is greater than the width of the transmission seat 9, and the length of the punching knife seat 12 is less than the width of the punching seat 8.

[0028] The conveying seat 9 facilitates the delivery of the punched pins to the blanking port 17 , and the punching knife punches the positions inside the punching seat 8 on both sides of the conveying seat, so that the punched pins can be delivered through the conveying seat 9 .

[0029] like Figures 1-4 As shown, a through-opening 19 is provided in the middle of the two groups of material guide plates 18, and the blowing component includes a blowing pipe 20, which is snap-fitted with one side of one group of material guide plates 18, and one end of the blowing pipe 20 is connected and fixedly connected with an air supply pipe 21, and the air collecting component includes an air collecting pipe 24, which is snap-fitted with one side of the other group of material guide plates 18, and one end of the air collecting pipe 24 is connected and fixedly connected with an air suction pipe 25, the blowing pipe 20 and the air collecting pipe 24 are respectively connected with the two groups of through-openings 19, the air supply pipe 21 is connected to an external blowing device, and the air suction pipe 25 is connected to an external suction device, and the blowing equipment and the air suction equipment are both existing technology equipment.

[0030] When the punched pins are transported to one end through the conveying seat 9 and fall, the debris falls toward the discharge port 17 along with the pins. The guide plate 18 guides the falling pins. The air supply pipe 21 causes the blowing pipe 20 to blow the falling debris through the through port 19. The suction pipe 25 causes the air collecting pipe 24 to pass through the through port 19 to absorb the falling debris, so that the debris is collected in the air collecting pipe 24 and does not fall into the discharge port 17.

[0031] like Figure 4 As shown, one side of the two groups of guide plates 18 is fixedly connected to a slide rail 22, and the upper ends of the blowing pipe 20 and the air collecting pipe 24 are fixedly connected to a clamping plate 23, and the two groups of clamping plates 23 are respectively engaged with the two groups of slide rails 22.

[0033] like Figure 1 As shown, the feeding assembly includes a frame 2, which is fixed to the upper end of the machine base 1. Two groups of feeding rolls 3 are rotatably connected to one side of the upper end of the machine base 1, and two groups of electric guide rolls 4 are fixed to the other side of the upper end of the machine base 1. The two groups of electric guide rolls 4 cooperate with the two groups of feeding rolls 3 respectively.

[0035] like Figure 1 As shown, the upper end of the machine base 1 is fixedly connected to the second conveying base 15, and the second conveying base 15 is located below the discharge port 17. The upper end of the machine base 1 is clamped with a material receiving box 16, and the material receiving box 16 is located at one end of the second conveying base 15.

[0036] The pins dropped from the discharge port 17 fall onto the second conveying seat 15 and are transported to the receiving box 16 via the second conveying seat 15 .

[0037] The working principle of the wire harness needle cutting machine provided by the utility model is as follows:

[0038] The material strip passes through the upper end of the punching seat 8, and the punching cylinder 11 drives the punching knife seat 12 to punch the material roll. The punched pins fall into the discharge port 17 along with the punching seat 8. The blowing component and the air collecting component cooperate to absorb the debris that is about to reach the discharge port 17, preventing the debris from entering the discharge port 17 along with the pins, and preventing the debris from affecting the punching quality of the pins.

[0039] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
