[0016] A cutting method for a copper-based polyamide 6 masterbatch cutting device includes the following steps:

[0017] Step A: Grind;

[0018] The copper-based polyamide 6 masterbatch raw material, cooled by the water tank, is conveyed to the protective box. When it passes through the cutting gear, the teeth on the cutting gear cut the copper-based polyamide 6 masterbatch raw material, and the cut copper-based polyamide 6 masterbatch raw material becomes granular. It is then conveyed to the rotating drum through the connecting pipe. The rotating drum is provided with evenly distributed small holes. The copper-based polyamide 6 masterbatch granules of qualified size flow out through the small holes, while the unqualified copper-based polyamide 6 masterbatch granules are cut into qualified copper-based polyamide 6 masterbatch granules by the rotating cutting blade.

[0019] Step B: Transfer;

[0020] After the paste-like copper-based polyamide 6 masterbatch raw material is extruded from the extruder, it falls into the flow channel. The diverter plate first diverts the long strip of copper-based polyamide 6 masterbatch raw material to prevent it from mixing together during the conveying process and affecting the cutting effect. Then, it is conveyed to the first conveyor roller by the limiting plate. Under the conveying of the first conveyor roller, the long strip of copper-based polyamide 6 masterbatch raw material continues to move and then comes to the second conveyor roller. Under the conveying of the second conveyor roller, it passes through the limiting guide groove and is conveyed to the bottom of the extrusion gear. Then, the extrusion gear aligns and limits it and conveys it to the cutting gear. After the cutting gear completes the initial cutting, the copper-based polyamide 6 masterbatch particles come into the fixed cylinder through the connecting pipe. Under the conveying of the spiral blades, they are conveyed into the rotating cylinder. The copper-based polyamide 6 masterbatch particles of qualified size come into the fixed sleeve through the small hole on the rotating cylinder and flow out through the discharge port.

[0021] Step C: Linkage;

[0022] The rotating shaft drives the cutting blade and the actuating plate to rotate, and simultaneously drives the first gear to rotate. The rotating first gear drives the second gear to rotate, and at the same time, the third gear drives the fourth gear to rotate, which in turn drives the rotating drum to rotate. Due to the different speed changes from the second gear to the first gear and from the third gear to the fourth gear, the rotation speed of the drum is much lower than that of the rotating shaft. When the drum rotates, the fixed rod rotates with the drum. Each time the fixed rod rotates once, it will abut against the fixed block. The fixed block will rotate upward around the fixed seat under force. At the same time, the rotating rod compresses the spring, allowing the spring to store energy. When the fixed rod no longer abuts against the fixed block, the fixed block will rotate downward under the action of gravity and the push of the spring, and strike the rotating drum, causing the copper-based polyamide 6 masterbatch particles stuck in the small hole of the rotating drum to fall off, thus preventing the small hole on the rotating drum from being blocked.

[0023] Compared with the prior art, the present invention provides a copper-based polyamide 6 masterbatch cutting device and cutting method, which has the following beneficial effects:

[0024] 1. The copper-based polyamide 6 masterbatch cutting device and its cutting method use cutting gears to initially cut the copper-based polyamide 6 masterbatch, and then use a rotating drum to screen out the copper-based polyamide 6 masterbatch of qualified size. The unqualified ones are cut into qualified size particles by cutting blades. The double cutting improves the cutting efficiency of copper-based polyamide 6 masterbatch.

[0025] 2. The copper-based polyamide 6 masterbatch cutting device and its cutting method, through different speed changes from the second gear 30 to the first gear 29 and from the third gear 32 to the fourth gear 33, make the rotation speed of the drum much lower than that of the shaft, ensuring the cutting effect of the cutting blade, and at the same time allowing the copper-based polyamide 6 masterbatch to fall smoothly through the small hole on the drum onto the fixed sleeve.

[0026] 3. The copper-based polyamide 6 masterbatch cutting device and its cutting method use a fixed rod and a fixed block to work together, so that the fixed block hits the rotating drum at regular intervals, causing the copper-based polyamide 6 masterbatch particles stuck in the small hole of the rotating drum to fall off, thus avoiding clogging the small hole on the rotating drum.

[0027] 4. The copper-based polyamide 6 masterbatch cutting device and its cutting method use a cooling and conveying system consisting of a water tank, a water reservoir, a water outlet, a first water supply pipe, and a second water supply pipe to continuously cool the water, thus ensuring better cooling of the copper-based polyamide 6 masterbatch.

[0028] The parts of the device not mentioned herein are the same as or can be implemented using existing technologies. The present invention ensures that the copper-based polyamide 6 masterbatch particles are of the same size by the cooperation of the cutting gear, the rotating drum and the cutting blade, thereby improving the cutting efficiency of the copper-based polyamide 6 masterbatch.

[0041] Example 1:

[0042] Reference Figures 1-9A copper-based polyamide 6 masterbatch cutting device includes a support 1, a protective box 19, and a fixing sleeve 18. The protective box 19 and the fixing sleeve 18 are both fixedly connected to the support 1. The device also includes: a water storage tank 3, fixedly connected to the support 1; a water trough 2, fixedly connected to the water storage tank 3, with a first conveying roller 6 rotatably connected laterally via a bearing seat inside the water trough 2, one end of the water trough 2 being fixedly connected to the protective box 19; a second conveying roller 12, rotatably connected laterally via a bearing seat at the connection between the water trough 2 and the protective box 19; a pressing gear 14, rotatably connected to the protective box 19 via a bearing seat; a cutting gear 15, rotatably connected to the protective box 19 via a bearing seat, and the cutting gear 15 cooperating with the pressing gear 14; and a connecting pipe 16 located within the protective box 19. At the bottom of the 9th section, the connecting pipe 16 is connected to the protective box 19, and the other end of the connecting pipe 16 is connected to the fixed sleeve 18. A rotating shaft 28 is rotatably connected to the fixed sleeve 18 via a bearing seat. A connecting rod 31 is rotatably connected to the inner wall of the fixed sleeve 18. A second gear 30 and a third gear 32 are fixedly connected to the connecting rod 31. A first gear 29 is fixedly connected to the rotating shaft 28, and the first gear 29 meshes with the second gear 30. A fourth gear 33 meshes with the third gear 32 and is rotatably mounted on the rotating shaft 28. A rotating cylinder 34 is rotatably connected to the fixed sleeve 18. Specifically, the rotating shaft 28 rotatably passes through the rotating cylinder 34, allowing the rotating cylinder 34 to be rotatably connected to the fixed sleeve 18, and the rotating cylinder 34 and the rotating shaft 28 can rotate relative to each other. The fourth gear 33 is fixedly connected to the rotating cylinder 34. Specifically, the side wall of the fourth gear 33 is fixedly connected to the outer wall of one end of the rotating cylinder 34 via multiple connecting rods. Multiple actuating plates 36 and multiple cutting blades 37 are fixedly connected to one end of the rotating shaft 28 inside the rotating drum 34; a fixed seat 42 is fixedly connected to the inner wall of the fixed sleeve 18, and a fixed block 44 is rotatably connected to the fixed seat 42. Specifically, a rotating rod 43 is fixedly provided at one end of the fixed block 44, and the other end of the rotating rod 43 is rotatably connected to the fixed seat 42 through a pin. A compression spring 45 is fixedly installed between the rotating rod 43 and the fixed seat 42. A fixed rod 41 that cooperates with the fixed block 44 is fixedly provided on the outer wall of the rotating drum 34.

[0043] In this invention, during use, the copper-based polyamide 6 masterbatch raw material, cooled by the water tank 2, is conveyed to the protective box 19. When passing through the cutting gear 15, the teeth on the cutting gear 15 cut the copper-based polyamide 6 masterbatch raw material, turning it into granules. These granules are then conveyed to the rotating drum 34 via the connecting pipe 16. The rotating drum 34 has evenly distributed small holes. Qualified copper-based polyamide 6 masterbatch granules flow out through these holes, while unqualified granules are cut by the rotating cutting blade 37, becoming qualified copper-based polyamide 6 masterbatch granules. The rotating shaft... 28 drives the cutting blade 37 and the agitator plate 36 to rotate. The agitator plate 36 flips the copper-based polyamide 6 masterbatch particles, allowing them to pass through the small holes on the rotating drum 34 more quickly. The cutting blade 37 cuts the copper-based polyamide 6 masterbatch particles that are not up to size into particles of the correct size. Simultaneously, it drives the first gear 29 to rotate. The rotating first gear 29 drives the second gear 30 to rotate. At the same time, the rotating shaft 28 drives the third gear 32 to rotate synchronously with the second gear 30, causing the third gear 32 to drive the fourth gear 33 to rotate. Finally, the fourth gear 33 drives the rotating drum 34 to rotate. Due to the second... The different speed changes of gears 30 to the first gear 29 and 32 to the fourth gear 33 make the rotational speed of the rotating drum 34 much lower than that of the rotating shaft 28. As the rotating drum 34 rotates, the fixing rod 41 rotates with it. Each time the fixing rod 41 rotates one revolution, it abuts against the fixing block 44. The fixing block 44, under pressure, rotates upwards around the fixing seat 42. Simultaneously, the rotating rod 43 compresses the spring 45, causing the spring 45 to store energy. When the fixing rod 41 no longer abuts against the fixing block 44, the fixing block 44, under the action of gravity and the push of the spring 45, rotates downwards and strikes the rotating drum 34, causing it to lock into place. The copper-based polyamide 6 masterbatch particles inside the small hole of the rotating drum 34 fall out, preventing the small hole on the rotating drum 34 from being blocked. Among them, due to the different speed transmissions of the second gear 30 to the first gear 29 and the third gear 32 to the fourth gear 33, it is not only ensured that the cutting blade 37 can cut the unqualified copper-based polyamide 6 masterbatch particles, but also that the fixing block 44 can strike the rotating drum 34. This is because when the rotating drum 34 rotates too fast, the fixing rod 41 will frequently abut against the fixing block 44. Before the fixing block 44 can fall down, the fixing rod 41 will abut against the fixing block 44 again, thus making the striking effect of the fixing block 44 ineffective.

[0044] Example 2:

[0045] A water pump 20 is installed at the end of the water storage tank 3 away from the protective box 19. The water outlet end of the water pump 20 is connected to a water outlet pipe 39. The end of the water outlet pipe 39 outside the water storage tank 3 is fixedly connected to a diversion pipe 38. The diversion pipe 38 is connected to a first water supply pipe 9 and a second water supply pipe 40. The second water supply pipe 40 is connected to the water flow channel 2. A diversion plate 4 is fixedly connected inside the water flow channel 2. A limit plate 5 is fixedly connected inside the water flow channel 2. A spray pipe 7 is fixedly connected to the water flow channel 2. A spray nozzle 8 is provided at the bottom of the spray pipe 7. The first water supply pipe 9 is connected to the spray pipe 7. A water outlet 10 is provided inside the water flow channel 2, and the water outlet 10 corresponds to the water storage tank 3.

[0046] In this embodiment, the water pump 20 draws water from the water storage tank 3, which flows into the diversion pipe 38 through the outlet pipe 39. The water is then conveyed to the water flow tank 2 by the first water supply pipe 9 and the second water supply pipe 40. The first water supply pipe 9 conveys the water to the spray pipe 7, and then sprays it out by the spray nozzle 8 to cool the copper-based polyamide 6 masterbatch. The water accumulated in the water flow tank 2 flows into the water storage tank 3 through the outlet hole 10. The water pump 20 is located at the end of the water storage tank 3 away from the outlet hole 10. This ensures that the water with a certain temperature flowing out of the outlet hole 10 is cooled by the water storage tank 3 before it can be drawn by the water pump 20. This cools the water fed into the water flow tank 2 by the first water supply pipe 9 and the second water supply pipe 40 as much as possible, thereby improving the cooling effect on the copper-based polyamide 6 masterbatch raw material. The conveying system composed of the water flow tank 2, the water storage tank 3, the first water supply pipe 9 and the second water supply pipe 40 keeps the water cooling, ensuring better cooling of the copper-based polyamide 6 masterbatch.

[0047] Example 3:

[0048] The protective box 19 is provided with a limiting guide groove 13; a fixed cylinder 17 is fixedly connected to the bracket 1, one end of the fixed cylinder 17 is connected to the connecting pipe 16, and the other end of the fixed cylinder 17 is connected to the rotating drum 34 through the feeding pipe 48; a fifth drive unit 25 is provided on the fixed cylinder 17, and a rotating column 46 is rotatably connected inside the fixed cylinder 17. A spiral blade 47 is fixedly provided on the rotating column 46, and one end of the rotating column 46 is fixedly connected to the output end of the fifth drive unit 25.

[0049] In this embodiment, the limiting groove 13 limits the elongated copper-based polyamide 6 masterbatch raw material, allowing it to reach below the pressing gear 14, preventing the elongated copper-based polyamide 6 masterbatch raw material from tilting upwards, which would prevent the pressing gear 14 from contacting the elongated copper-based polyamide 6 masterbatch raw material. The internal power source of the fifth drive unit 25 is a servo motor. The fifth drive unit 25 drives the rotating column 46 to rotate the spiral blade 47. The rotating spiral blade 47 pumps the copper-based polyamide 6 masterbatch particles that have entered the fixed cylinder 17 into the feeding pipe 48. The feeding pipe 48 is inclined and is horizontal with the rotating cylinder 34, so that the copper-based polyamide 6 masterbatch particles that have entered the feeding pipe 48 can smoothly slide into the rotating cylinder 34.

[0050] Example 4:

[0051] A support plate 27 is fixedly connected to the bracket 1, and a fixed sleeve 18 is fixedly connected to the support plate 27; a rotating rod 43 is rotatably connected to the fixed seat 42, and a fixed block 44 is fixedly connected to the end of the rotating rod 43 away from the fixed seat 42; a spring 45 is provided between the fixed seat 42 and the rotating rod 43; a sixth drive part 26 is provided on the fixed sleeve 18, and the end of the rotating shaft 28 located outside the fixed sleeve 18 is fixedly connected to the output end of the sixth drive part 26.

[0052] In this embodiment, the internal power source of the sixth drive unit 26 is a servo motor. The support plate 27 supports the fixed sleeve 18, making the fixed sleeve 18 more stable. The fixed rod 41 abuts against the fixed block 44 with each rotation and pushes the fixed block 44, causing the rotating rod 43 to rotate upward around the fixed seat 42. At this time, the rotating rod 43 compresses the spring 45, allowing the spring 45 to store energy. When the fixed rod 41 no longer abuts against the fixed block 44, the fixed block 44 rotates downward under the action of gravity and the push of the spring 45, and strikes the rotating cylinder 34. The striking of the fixed block 44 causes the rotating cylinder 34 to vibrate, thereby causing the copper-based polyamide 6 masterbatch particles stuck in the small hole of the rotating cylinder 34 to fall off, avoiding clogging the small hole on the rotating cylinder 34.

[0053] Example 5:

[0054] The water tank 2 is provided with a first drive unit 21, and the connection between the protective box 19 and the water tank 2 is provided with a second drive unit 22. The protective box 19 is provided with a third drive unit 23 and a fourth drive unit 24 respectively. The end of the first conveying roller 6 located outside the water tank 2 is fixedly connected to the output end of the first drive unit 21. The end of the second conveying roller 12 located outside the protective box 19 is fixedly connected to the output end of the second drive unit 22. The end of the pressing gear 14 located outside the protective box 19 is fixedly connected to the output end of the third drive unit 23. The end of the cutting gear 15 located outside the protective box 19 is fixedly connected to the output end of the fourth drive unit 24.

[0055] In this embodiment, the power source in the first drive unit 21, the second drive unit 22, the third drive unit 23, and the fourth drive unit 24 is a servo motor. The servo motor can control the speed, rotation direction, and rotation angle with very high accuracy. It can convert voltage signals into torque and speed to drive the controlled object. Here, it will not be described in detail. Among them, the first drive unit 21 drives the first conveyor roller to rotate, the second drive unit 22 drives the second conveyor roller 12 to rotate, the third drive unit 23 drives the pressing gear 14 to rotate, and the fourth drive unit 24 drives the cutting gear 15 to rotate.

[0056] Example 6:

[0057] A cutting method for a copper-based polyamide 6 masterbatch cutting device includes the following steps:

[0058] Step A: Grind;

[0059] The copper-based polyamide 6 masterbatch raw material, cooled by the water tank 2, is conveyed to the protective box 19. When passing through the cutting gear 15, the teeth on the cutting gear 15 cut the copper-based polyamide 6 masterbatch raw material, and the cut copper-based polyamide 6 masterbatch raw material becomes granular. It is conveyed to the rotating drum 34 through the connecting pipe 16. The rotating drum 34 is provided with evenly distributed small holes. The copper-based polyamide 6 masterbatch granules of qualified size flow out through the small holes, while the unqualified copper-based polyamide 6 masterbatch granules are cut into qualified copper-based polyamide 6 masterbatch granules by the rotating cutting blade 37.

[0060] Step B: Transfer;

[0061] After the paste-like copper-based polyamide 6 masterbatch raw material is extruded from the extruder, it falls into the flow tank 2. The diverter plate 4 first diverts the long strip of copper-based polyamide 6 masterbatch raw material to prevent it from mixing together during the conveying process and affecting the cutting effect. Then, it is conveyed to the first conveyor roller 6 through the limiting plate 5. Under the conveying of the first conveyor roller 6, the long strip of copper-based polyamide 6 masterbatch raw material continues to move and then comes to the second conveyor roller 12. Under the conveying of the second conveyor roller 12, it passes through the limiting guide groove 13 and is conveyed to the bottom of the extrusion gear 14. Then, the extrusion gear 14 aligns and limits it and conveys it to the cutting gear 15. After the cutting gear 15 completes the initial cutting, the copper-based polyamide 6 masterbatch particles come into the fixed cylinder 17 through the connecting pipe 16. Under the conveying of the spiral blade 47, it is conveyed into the rotating drum 34. The copper-based polyamide 6 masterbatch particles of qualified size come into the fixed sleeve 18 through the small hole on the rotating drum 34 and flow out through the discharge port 35.

[0062] Step C: Linkage;

[0063] The rotating shaft 28 drives the cutting blade 37 and the actuating plate 36 to rotate, and simultaneously drives the first gear 29 to rotate. The rotating first gear 29 drives the second gear 30 to rotate, and simultaneously drives the third gear 32 to rotate synchronously with the second gear 30, causing the third gear 32 to drive the fourth gear 33 to rotate, and finally causing the fourth gear 33 to drive the rotating drum 34 to rotate. Due to the different speed changes from the second gear 30 to the first gear 29 and from the third gear 32 to the fourth gear 33, the rotational speed of the rotating drum 34 is much lower than that of the rotating shaft 28. During rotation, the fixed rod 41 rotates with the rotating drum 34. Each time the fixed rod 41 rotates once, it will abut against the fixed block 44. The fixed block 44 rotates upward around the fixed seat 42 under force. At the same time, the rotating rod 43 compresses the spring 45, allowing the spring 45 to store energy. When the fixed rod 41 no longer abuts against the fixed block 44, the fixed block 44 rotates downward under the action of gravity and the push of the spring 45, and strikes the rotating drum 34, causing the copper-based polyamide 6 masterbatch particles stuck in the small hole of the rotating drum 34 to fall out, thus preventing the small hole on the rotating drum 34 from being blocked.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

10. A cutting method for a copper-based polyamide 6 masterbatch cutting device according to any one of claims 1-9, characterized in that, Includes the following steps: Step A: Grind; The copper-based polyamide 6 masterbatch raw material cooled by the water tank (2) is conveyed to the protective box (19). When it passes through the cutting gear (15), the teeth on the cutting gear (15) cut the copper-based polyamide 6 masterbatch raw material. The cut copper-based polyamide 6 masterbatch raw material becomes granular and is conveyed to the rotating drum (34) through the connecting pipe (16). The rotating drum (34) is provided with evenly distributed small holes. The copper-based polyamide 6 masterbatch particles of qualified size flow out through the small holes. The unqualified copper-based polyamide 6 masterbatch particles are cut by the rotating cutting blade (37) and become copper-based polyamide 6 masterbatch particles of qualified size. Step B: Transfer; After the paste-like copper-based polyamide 6 masterbatch raw material is extruded from the extruder, it falls into the flow tank (2). The diverting plate (4) first diverts the long strip of copper-based polyamide 6 masterbatch raw material to prevent it from mixing together during the conveying process and affecting the cutting effect. Then, it is conveyed to the first conveying roller (6) through the limiting plate (5). Under the conveying of the first conveying roller (6), the long strip of copper-based polyamide 6 masterbatch raw material continues to move and then comes to the second conveying roller (12). Under the conveying of the second conveying roller (12), it passes through the limiting guide groove ( 13), and conveyed to the bottom of the extrusion gear (14), then the extrusion gear (14) aligns and limits it, and conveys it to the cutting gear (15). After the cutting gear (15) completes the initial cutting, the copper polyamide 6 masterbatch particles come to the fixed cylinder (17) through the connecting pipe (16), and are conveyed to the rotating cylinder (34) under the transmission of the spiral blade (47). The copper polyamide 6 masterbatch particles of qualified size come to the fixed sleeve (18) through the small hole on the rotating cylinder (34) and flow out through the discharge port (35); Step C: Linkage; The rotating shaft (28) drives the cutting blade (37) and the actuating plate (36) to rotate, and simultaneously drives the first gear (29) to rotate. The rotating first gear (29) drives the second gear (30) to rotate, and simultaneously drives the third gear (32) to rotate synchronously with the second gear (30), so that the third gear (32) drives the fourth gear (33) to rotate, and finally the fourth gear (33) drives the rotating drum (34) to rotate. Due to the different speed changes from the second gear (30) to the first gear (29) and from the third gear (32) to the fourth gear (33), the rotational speed of the rotating drum (34) is much lower than that of the rotating shaft (28); in the rotating drum (3 4) When rotating, the fixed rod (41) follows the rotating drum (34) to rotate. Each time the fixed rod (41) rotates once, the fixed rod (41) will abut against the fixed block (44). The fixed block (44) rotates upward around the fixed seat (42) under force. At the same time, the rotating rod (43) compresses the spring (45) to store energy. When the fixed rod (41) no longer abuts against the fixed block (44), the fixed block (44) rotates downward under the action of gravity and the push of the spring (45) and hits the rotating drum (34), causing the copper-based polyamide 6 masterbatch particles stuck in the small hole of the rotating drum (34) to fall off, avoiding blocking the small hole on the rotating drum (34).
