DETAILED DESCRIPTION

[0019] The above scheme is further described below in conjunction with specific examples. It should be understood that these examples are used to illustrate the present application and are not limited to the scope of the present application. The implementation conditions adopted in the examples can be further adjusted according to the conditions of the specific manufacturer, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0020] Embodiment 1: A production system of nylon chips, such as Figure 1-Figure 3 As shown, it includes a bracket 1, the bracket 1 is fixedly connected to a shell 2, the shell 2 is rotatably connected to a knife seat 3, a first feed roller 4 and a second feed roller 5, a fixed knife 6 is fixed in the shell 2, the knife seat 3 is detachably installed with a rotating knife 7 evenly distributed in the circumference, the first feed roller 4 and the second feed roller 5 are driven by a gear set, and the knife seat 3 and the first feed roller 4 are driven by a pulley belt.

[0021] In the above scheme, the rotary cutter 7 is intended to be replaceable separately to reduce costs. The housing 2 is provided with a feed port and a discharge port, the feed port is located at the upper side, and the discharge port is located at the lower side. The feed port is used to allow strip nylon to enter, and the discharge port is used to allow nylon slices to be discharged. The first feed roller 4 and the second feed roller 5 are located at the right part of the housing 2, and the knife seat 3 and the fixed knife 6 are located at the left side of the first feed roller 4 and the second feed roller 5. The rotary cutter 7 has a fixed part and a blade part. The width of the fixed part of the rotary cutter 7 is greater than the width of the blade part of the rotary cutter 7 to prevent the rotary cutter 7 from falling off the knife seat 3.

[0022] like Figure 1 and Figure 2 As shown, the bracket 1 is fixedly connected to the motor 8, the housing 2 is fixedly connected to the first push rod 9, the telescopic end of the first push rod 9 is rotatably connected to the rotating shaft 10, the rotating shaft 10 and the output shaft of the motor 8 are driven by a pulley belt, the housing 2 is provided with a tensioning member for adjusting the tension of the belt between the rotating shaft 10 and the output shaft of the motor 8, and the rotating shaft 10 and the tool holder 3 are driven by friction.

[0023] In the above scheme, it is intended to provide power for the rotation of the knife seat 3, the first feed roller 4 and the second feed roller 5. The first push rod 9 is used to adjust the position of the rotating shaft 10. The rotating shaft 10 and the knife seat 3 are both provided with friction wheels, and the two friction wheels are driven by friction.

[0024] Working process: When using this device, first start the motor 8. The output shaft of the motor 8 drives the rotating shaft 10 to rotate through the pulley belt. The rotating shaft 10 drives the knife seat 3 to rotate through two friction wheels. The knife seat 3 drives the rotary knife 7 thereon to rotate. The knife seat 3 drives the first feed roller 4 to rotate through the pulley belt. The first feed roller 4 drives the second feed roller 5 to rotate through the gear set. Then, the raw material is inserted between the first feed roller 4 and the second feed roller 5. The first feed roller 4 and the second feed roller 5 move with the raw material clamped. Then, the fixed knife 6 and the rotary knife 7 cut the raw material into particles. As the use time increases, the blade of the rotary knife 7 gradually becomes less sharp, resulting in uneven cutting particle size. At this time, turn off the motor 8, and push the less sharp rotary knife 7 to be removed from the knife seat 3, and then insert the new rotary knife 7 into the knife seat 3. Then, the above steps can be repeated to continue working.

[0025] Example 2: Figure 1 , Figure 2 and Figure 4 As shown, it also includes a loading shell 11, which is fixed to the outer shell 2. A plurality of rotary cutters 7 are placed in the loading shell 11. The outer shell 2 is fixedly connected to a second push rod 12. The telescopic end of the second push rod 12 is fixedly connected to a pusher holder 121. The pusher holder 121 is used to push the rotary cutter 7 in the loading shell 11.

[0026] In the above scheme, the rotary cutter 7 is intended to be replaced automatically. The loading shell 11 is composed of a connecting piece and a rectangular frame. The rectangular frame of the loading shell 11 is provided with a notch for the knife pusher 121 to pass through. The second push rod 12 is used to drive the knife pusher 121 to move.

[0027] like Figure 3 As shown, the knife seat 3 is provided with connecting grooves 301 evenly distributed in the circumference, and the number of the connecting grooves 301 is equal to the number of the rotary cutters 7. The connecting groove 301 is slidably connected to the limiting column 13 on one side close to the adjacent rotary cutter 7. A first spring is provided between the limiting column 13 and the knife seat 3. The rotary cutter 7 is provided with a groove, and the limiting column 13 is inserted into the groove to limit the rotary cutter 7. The connecting groove 301 is slidably connected to the sliding column 14 on one side close to the rotating shaft 10.

[0028] In the above scheme, it is intended to detect whether the rotary cutter 7 needs to be replaced. The limit column 13 is composed of a hemisphere and a cylinder. The first spring between the limit column 13 and the cutter seat 3 is initially in a compressed state, which is used to fix the rotary cutter 7 with the limit column 13. However, when the thrust force on the rotary cutter 7 is greater than the resistance of the limit column 13 to the rotary cutter 7, the rotary cutter 7 will squeeze the limit column 13 to move and compress the adjacent first spring. The connecting groove 301 is filled with a liquid for transmission, such as hydraulic oil. A seal is provided between the limit column 13 and the sliding column 14 and the connecting groove 301.

[0029] like Figure 3 As shown, the tool holder 3 is slidably connected with push plates 15 evenly distributed in the circumferential direction, the number of the push plates 15 is equal to the number of the rotary knives 7, a second spring is arranged between the push plates 15 and the tool holder 3, and the push plates 15 and the adjacent rotary knives 7 are pressed against each other.

[0030] In the above scheme, the purpose is to reset the rotary cutter 7. When the rotary cutter 7 is slightly worn but not to the extent that it needs to be replaced, the rotary cutter 7 will be slightly displaced, but it is unable to completely squeeze the limiting column 13 into the connecting groove 301. At this time, after the rotary cutter 7 is displaced, the push plate 15 pushes the rotary cutter 7 to reset under the action of the adjacent second spring. The width of the push plate 15 is greater than the width of the fixed portion of the rotary cutter 7 to prevent the push plate 15 from moving too far and blocking the installation of the rotary cutter 7.

[0031] like Figure 4 and Figure 5 As shown, the knife seat 3 is slidably connected with limit blocks 16 evenly distributed in the circumference, the number of limit blocks 16 is equal to the number of rotary knives 7, a third spring is arranged between the limit blocks 16 and the knife seat 3, and the sliding column 14 is provided with an inclined groove, and the limit blocks 16 are inserted into it to limit the sliding column 14.

[0032] In the above scheme, the sliding column 14 is fixed. The limit block 16 is provided with two symmetrically distributed inclined surfaces, the third spring between the limit block 16 and the knife seat 3 is initially in a compressed state, and the maximum resistance of the limit block 16 to the sliding column 14 is greater than the elastic force of the adjacent first spring of the limit column 13, thereby preventing the sliding column 14 from retracting immediately after being extended.

[0033] like Figure 6 As shown, the housing 2 is fixedly connected to a fixed shell 17 , the fixed shell 17 is slidably connected to a sliding rod 18 , the sliding rod 18 is fixedly connected to a blocking plate 19 , a fourth spring is provided between the blocking plate 19 and the fixed shell 17 , and the blocking plate 19 is used to squeeze the sliding column 14 .

[0034] In the above solution, the sliding column 14 is blocked to stop the knife seat 3 from rotating. The fourth spring between the blocking plate 19 and the fixed shell 17 is used to buffer the sliding column 14 to prevent the sliding column 14 from being directly blocked and damaged.

[0035] like Figure 4 and Figure 6 As shown, the fixed shell 17 is slidably connected to the limiting member 20, a tension spring is arranged between the limiting member 20 and the fixed shell 17, the sliding rod 18 is provided with a limiting groove, the limiting member 20 is inserted therein to limit the sliding rod 18, and the tool pusher 121 is fixedly connected to the extrusion rod 21, which is used to extrude the limiting member 20.

[0036] In the above scheme, the purpose is to limit and release the sliding rod 18. The limiting member 20 is composed of a rod with an inclined surface, a plate for mounting a spring, and a block for squeezing the squeezing rod 21. The tension spring between the limiting member 20 and the fixed shell 17 is initially in a stretched state.

[0037] like Figure 4 As shown, the tool pusher 121 is slidably connected to a slide bar 22 , the slide bar 22 is fixedly connected to a pressing plate 23 , a fifth spring is provided between the pressing plate 23 and the tool pusher 121 , and the pressing plate 23 is used to press the sliding column 14 .

[0038] In the above scheme, the purpose is to push the sliding column 14 to reset it. When the extrusion plate 23 contacts the sliding column 14, the groove of the rotary cutter 7 is not aligned with the limiting column 13, so the sliding column 14 cannot move at this time, and the extrusion plate 23 will compress the fifth spring between it and the pusher frame 121. When the groove of the rotary cutter 7 is aligned with the limiting column 13, the sum of the elastic force of the fifth spring and the elastic force of the first spring adjacent to the limiting column 13 is greater than the resistance of the limiting block 16 to the sliding column 14, so that the sliding column 14 is reset.

[0039] Working process: when the blade of the rotary cutter 7 is not sharp enough, the resistance encountered by the rotary cutter 7 when cutting the raw material increases. At this time, the rotary cutter 7 moves into the cutter seat 3 and squeezes the limit column 13. The limit column 13 moves into the connecting groove 301 and squeezes the adjacent first spring. The limit column 13 hydraulically drives the sliding column 14 to move out of the connecting groove 301. The limit block 16 is inserted into the inclined groove on the sliding column 14 under the action of the adjacent third spring, so that the limit column 13 will not be reset under the action of the adjacent first spring.

[0040] When the knife seat 3 drives the sliding column 14 to rotate until it contacts the blocking plate 19, and then the sliding column 14 squeezes the blocking plate 19 to move to the right and compresses the adjacent fourth spring, the blocking plate 19 drives the sliding rod 18 to move, and the sliding rod 18 stops moving after moving to the limit position. At this time, the limiting member 20 is inserted into the limiting groove of the sliding rod 18 under the action of the adjacent tension spring, and at the same time, the telescopic end of the first push rod 9 contracts, driving the rotating shaft 10 to move downward, so that the friction wheel between the knife seat 3 and the rotating shaft 10 is separated. At this time, the knife seat 3 stops rotating, and then the second push rod 12 is started, and the telescopic end of the second push rod 12 contracts, driving the push knife holder 121 to move, and the push knife holder 121 pushes the new rotary knife 7 in the loading shell 11 to move. At this time, the new rotary knife 7 moves backward and then contacts the not sharp rotary knife 7, thereby pushing out the not sharp rotary knife 7 so that the new rotary knife 7 replaces it.

[0041] When the knife pusher 121 pushes the new rotary knife 7 to move, the knife pusher 121 drives the sliding rod 22 and the extrusion plate 23 to move, and the extrusion plate 23 stops moving when it contacts the sliding column 14. At this time, the extrusion rod 21 contacts the limit member 20, and then the knife pusher 121 continues to move, and the sliding rod 22 and the extrusion plate 23 slide relative to the knife pusher 121. The extrusion plate 23 compresses the adjacent fifth spring. At this time, the right side of the knife pusher 121 is against the left side of the blocking plate 19, and the extrusion rod 21 continues to move backward, extruding the limit member 20 to move upward and stretching the adjacent tension spring, so that the limit member 20 is separated from the sliding rod 18.

[0042] When the new rotary cutter 7 is replaced, the limit column 13 is aligned with the groove on the new rotary cutter 7. At this time, the extrusion plate 23 pushes the sliding column 14 to reset under the action of the adjacent fifth spring. The sliding column 14 squeezes the limit block 16, so that the limit block 16 compresses the adjacent third spring and resets. At the same time, the sliding column 14 drives the limit column 13 to reset. At this point, the replacement of the rotary cutter 7 is completed, and then the telescopic end of the second push rod 12 extends, driving the push knife holder 121 to reset. After the push knife holder 121 is separated from the blocking plate 19, the blocking plate 19 is reset under the action of the adjacent fourth spring, and then the extrusion rod 21 is separated from the limit member 20. When the push knife holder 121 is reset, the telescopic end of the first push rod 9 extends, pushing the rotating shaft 10 to reset, thereby restoring the transmission between the rotating shaft 10 and the knife seat 3, so that the device continues to work.

[0043] Example 3: Figure 6 As shown, it also includes a friction block 24, the outer shell 2 is provided with a slide groove 201, the friction block 24 is slidably connected in the slide groove 201, the friction block 24 is used to stop the knife seat 3, the slide groove 201 is slidably connected with a sliding plate 25, a sixth spring and a thin rope are provided between the sliding plate 25 and the friction block 24, and the slide groove 201 is connected to the fixed shell 17.

[0044] In the above scheme, the blade holder 3 is braked to prevent the blade holder 3 from reversing, and to ensure that the rotary blade 7 to be replaced is aligned with the new rotary blade 7. A friction material is provided on the side of the friction block 24 close to the blade holder 3 to increase the friction between the two. The slide groove 201 and the fixed shell 17 are connected by a pipeline, and both are filled with liquid for transmission, such as hydraulic oil. Seals are provided between the fixed shell 17 and the sliding rod 18 and between the sliding plate 25 and the slide groove 201. The sixth spring between the sliding plate 25 and the friction block 24 is initially in a compressed state, and the thin ropes in the brackets of the two are initially in a tight state.

[0045] Working process: when the sliding rod 18 moves to the right, the sliding rod 18 presses the liquid in the fixed shell 17 into the slide groove 201 through the pipeline. The liquid in the slide groove 201 increases, pushing the sliding plate 25 to move to the left. The sliding plate 25 pushes the friction block 24 to move through the adjacent sixth spring, so that the friction block 24 contacts the knife seat 3, and then the sliding plate 25 continues to move to pressurize the sixth spring. At this time, the thin rope between the friction block 24 and the sliding plate 25 is loose, thereby increasing the friction force of the friction block 24 on the knife seat 3 to brake the knife seat 3 and prevent the knife seat 3 from rotating. When the sliding rod 18 is reset, the sliding rod 18 sucks the liquid in the slide groove 201 back into the fixed shell 17. At this time, the sliding plate 25 begins to reset and gradually straightens the adjacent thin rope. When the thin rope is straightened, the sliding plate 25 pulls the friction block 24 to separate from the knife seat 3 through the thin rope.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to the embodiments without departing from the principles and spirit of the invention.
