[0030] In the embodiment, considering that the polypropylene capacitor film is just extruded from the extruder, the surface is still sticky, and it is easy to adhere to the inside of the embedded groove 2, which causes the embedded groove 2 to be uneven, affecting the stability of subsequent clamping, therefore, by setting the cleaning mechanism, when there are residues adhered to the inside of the embedded groove 2, the motor 6 is started to drive the screw rod 7 to rotate, referring to Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , the screw rod 7 rotates while driving the transmission block 8 to reciprocate along the trajectory of the sliding block 24 and the sliding groove 25, and the transmission block 8 drives the connecting frame 9, the scraper 10 and the broken hole needle 11 to reciprocate, when encountering residues, the broken hole needle 11 first enters the inside of the residues to break them, and then the scraper 10 can scrape off the residues, so that the inside of the embedded groove 2 becomes flat, thereby improving the stability of the subsequent pressing plate 3 clamping the polypropylene capacitor film.

[0031] One end of the screw rod 7 is provided with a bearing 23, and is rotatably connected with the inner wall of the transmission frame 5 through the bearing 23.​

[0032] The bearing 23 is arranged in the embodiment, the screw rod 7 can be supported, the rotation of the screw rod 7 is limited to around the bearing 23, and the smoothness and stability during rotation are improved.

[0033] The top and bottom of the transmission block 8 are fixedly connected with sliding blocks 24, and the inner wall of the transmission frame 5 is provided with sliding grooves 25 matched with the sliding blocks 24.

[0034] The sliding blocks 24 and the sliding grooves 25 are arranged in the embodiment, when the screw rod 7 rotates to drive the transmission block 8, the movement track of the transmission block 8 and other structures is limited to along the sliding blocks 24 and the sliding grooves 25, and the movement track is limited.

[0035] The number of the broken hole needles 11 is several, and the broken hole needles 11 are uniformly distributed on one side of the scraper 10.

[0036] The several broken hole needles 11 are arranged in the embodiment, the residual material is broken by the several broken hole needles 11 entering the residual material at the same time, and the residual material is more easily removed by the scraper 10. Embodiment two

[0037] On the basis of the embodiment one, the cleaning mechanism can break the residual material by the broken hole needles 11, and then remove the residual material by the scraper 10, but part of the residual material is adhered to the surface of the broken hole needles 11, and the cleaning effect is affected, the air injection mechanism includes the air injection tank 12 fixedly connected to one side of the connecting frame 9 and the air collecting tank 13, one side of the air injection tank 12 is fixedly communicated with two air injection pipes 14 through the one-way pressure valve, one side of the air collecting tank 13 is fixedly communicated with the air inlet pipe 15 through the first one-way valve, the top of the air collecting tank 13 is fixedly communicated with the transmission pipe 16 through the second one-way valve, the top of the transmission pipe 16 is fixedly communicated with the bottom of the air injection tank 12, the air collecting tank 13 is provided with the pushing block 17, the bottom of the pushing block 17 is fixedly connected with the pushing rod 18, the bottom of the pushing rod 18 penetrates to the bottom of the air collecting tank 13, and is fixedly connected with the extrusion block 19, one side of the transmission frame 5 is fixedly connected with the several extrusion rods 20 matched with the extrusion block 19, the bottom of the pushing block 17 is fixedly connected with the tension spring 21, and the bottom of the tension spring 21 is fixedly connected with the inner wall of the air collecting tank 13.

[0038] The cleaning mechanism can break the residues by the broken hole needle 11, and then remove them by the scraper 10. However, part of the residues will adhere to the surface of the broken hole needle 11, affecting the cleaning effect. Therefore, by setting the air injection mechanism, the air injection mechanism can move reciprocatingly while the connecting frame 9 moves reciprocatingly. When the slope part of the extrusion block 19 in the gas collecting mechanism contacts the surface of the extrusion rod 20, the extrusion block 19 will drive the push rod 18, the push block 17 and the piston plate 22 to move upward due to the extrusion, so as to extrude the gas in the gas collecting tank 13, and make the gas in the gas collecting tank 13 enter the air injection tank 12 through the transmission pipe 16. When the extrusion block 19 does not contact the extrusion rod 20, the tension of the tension spring 21 will drive the push block 17 and the piston plate 22 to move downward. At this time, the gas collecting tank 13 is under negative pressure, and the gas will enter the air inlet pipe 15, and the cycle is repeated, so as to compress the gas in the air injection pipe 14 intermittently. When the air pressure in the air injection tank 12 reaches the limit of the one-way pressure valve, the compressed gas will be intermittently injected to the broken hole needle 11 through the air injection pipe 14, so as to blow off the residues;

[0039] It should be noted that the first one-way valve is a valve that can only intake air into the gas collecting tank 13, and the second one-way valve is a valve that can only exhaust air from the gas collecting tank 13

[0040] The top of the push block 17 is fixedly connected with the piston plate 22, and the material of the piston plate 22 is rubber.

[0041] In the embodiment, the piston plate 22 is arranged, so that the gas collecting tank 13 is a closed cavity, so as to collect and transmit the gas.

[0042] The two sides of the extrusion block 19 are in a slope shape.

[0043] In the embodiment, the two sides of the extrusion block 19 are arranged in a slope shape, so that when the slope part of the extrusion block 19 contacts the surface of the extrusion rod 20, the extrusion block 19 will drive the push rod 18, the push block 17 and the piston plate 22 to move upward due to the extrusion, so as to play a transmission role.

[0044] Working principle: when the embedded groove 2 has residues adhered therein, the motor 6 is started to drive the lead screw 7 to rotate, referring to Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , the lead screw 7 rotates to drive the transmission block 8 to move reciprocatingly along the track of the sliding block 24 and the sliding groove 25, and the transmission block 8 drives the connecting frame 9, the scraper 10 and the broken hole needle 11 to move reciprocatingly. When the residues are encountered, the broken hole needle 11 will first enter the residues to break them, and then the scraper 10 can scrape off the residues, so that the inside of the embedded groove 2 becomes flat, thereby improving the stability of the polypropylene capacitor film clamped by the subsequent pressing plate 3;

[0045] When the connecting frame 9 reciprocates, the air injection mechanism reciprocates, when the slope part of the extrusion block 19 in the air collecting mechanism contacts the surface of the extrusion rod 20, the extrusion block 19 is affected by extrusion, drives the push rod 18, the push block 17 and the piston plate 22 to move upward, extrudes the gas in the air collecting tank 13, and the gas in the air collecting tank 13 enters the inside of the air injection tank 12 through the transmission pipe 16, when the extrusion block 19 does not contact the extrusion rod 20, the tension of the tension spring 21 drives the push block 17 and the piston plate 22 to move downward, at this time, the air collecting tank 13 is negative pressure, the gas enters from the air inlet pipe 15, and the cycle is repeated, and the compressed gas is intermittently compressed into the air injection pipe 14, when the air pressure in the air injection tank 12 reaches the limit of the one-way pressure valve, the compressed gas is intermittently injected to the broken hole needle 11 through the air injection pipe 14, and the residual material is blown off.

[0046] It should be noted that the electric push rod 4 and the motor 6 are devices or equipment existing in the prior art or devices or equipment that can be realized in the prior art, and the power supply specific composition and principle of the electric push rod 4 and the motor 6 are clear to those skilled in the art, and therefore will not be described in detail.
