Specifically, a control terminal (the control terminal belongs to the prior art and is not shown in the figure) is arranged outside the support plate 101, and a control system is arranged inside the control terminal and is used for controlling all the electric elements on the dividing device 1 to operate.
The control terminal includes the peripheral hardware casing that is connected with extension board 101, and the inside control mainboard that is equipped with of peripheral hardware casing is equipped with control chip on the control mainboard, and control system has been compiled to control chip's inside, and all electric elements of this device inside all are connected with the control terminal electricity, and the existence form of control terminal belongs to prior art, and it is unnecessary here to repeat.
In the initial state, the control system supplies current to the inside of the electromagnetic roller 303, the electromagnetic roller 303 generates attraction force attracted to the magnetic block 203 after supplying the current, and the electromagnetic roller 303 positioned at two sides of the dividing knife 204 clamps the magnetic block 203 (specifically, as shown in fig. 12); the pushing member 402 is in an elongated state, and the pushing member 402 presses the pressing member 404 through the pressing plate 403 so that the expansion member 603 is in an expanded state (the expansion member 603 includes an expansion balloon that encapsulates the driving roller 601, as shown in fig. 9 specifically).
When the plastic film 7 is used, the plastic film 7 enters from the driving roller 601 on the left side of the support plate 101, is split by the splitting roller 102 on the top of the support plate 101, and is guided out from the driving roller 601 on the right side of the support plate 101, and in the process, the plastic film 7 is split by the splitting knives 204 distributed on the splitting roller 102 in an array manner, and the whole plastic film 7 is split into equal amount of embryo filaments by the splitting knives 204.
In the process of cutting by the dividing knife 204, the plastic film 7 and the embryo wire are respectively contacted with the rotating rollers 302 at two sides of the dividing knife 204, in the process of pulling the embryo wire by the heating and stretching device 14, the plastic film 7 and the embryo wire are respectively extruded by the corresponding rotating rollers 302, after the rotating rollers 302 are extruded, the installation block 304 is extruded by the electromagnetic roller 303, the elastic piece 306 at the bottom of the installation block 304 is compressed, and the control system can obtain the tension change of the plastic film 7 at the dividing knife 204 by detecting the compression amount of the elastic piece 306 corresponding to the two rotating rollers 302.
It should be noted that: in this embodiment, two ends of the dividing roller 102 are fixedly connected with two support plates 101 respectively; the rotating roller 302 is rotatably connected to the middle part of the electromagnetic roller 303, and in the running process of the plastic film 7, the lower surface of the plastic film 7 is in extrusion contact with the rotating roller 302, and the rotating roller 302 rotates, so that excessive friction between the plastic film 7 and the dividing roller 102 is avoided, and the quality of the divided embryo yarn is influenced.
Meanwhile, as the positions of the two electromagnetic rollers 303 (namely the centers of the rotating rollers 302) are lower than the positions of the quadrant points at the top of the dividing roller 102, gaps (particularly shown in fig. 12) exist between the rotating rollers 302 and the electromagnetic rollers 303 in the running process of the plastic film 7, so that air can circulate in the gaps, the situation that the edges of the embryo wires are softened due to overheating of the dividing knife 204 under the action of friction force in the long-time use process of the dividing knife 204 is avoided, and the softened parts are easy to adhere to the outer walls of the dividing knife 204, so that the subsequent cutting quality is affected.
It should be noted that: in this embodiment, a pressure sensor is disposed at the connection between the elastic member 306 and the limiting groove 305, and the control system can obtain the compression amount of the elastic member 306 by detecting the value of the pressure sensor.
When the control system detects that the compression amount of the elastic pieces 306 at the two sides of the dividing knife 204 is in a stable state, the tension applied to the plastic film 7 and the embryo wires by the driving rollers 601 at the two sides of the support plate 101 is indicated to be in a stable state, and the device is in a normal running state.
When the control system detects that the compression amount of the elastic pieces 306 at two sides of the dividing knife 204 exceeds a set value (namely, the compression amount is too large), the driving rollers 601 at two sides of the support plate 101 exert too large tension on the plastic film 7 and the embryo wires, at this time, the control system controls the pushing pieces 402 on the support frame 401 to shrink (the pushing pieces 402 comprise electric push rods), in the process that the pushing pieces 402 shrink, the extruding pieces 404 are stretched through the extruding plates 403 (the extruding pieces 404 comprise corrugated pipes), after the extruding pieces 404 are stretched, negative pressure is generated in the extruding pieces 404, and as two ends of the air outlet pipe 405 are respectively communicated with the extruding pieces 404 and the expansion pieces 603, the extruding pieces 404 suck air in the extruding pieces 404 through the air outlet pipe 405, and the diameters of the driving rollers 601 are reduced in a phase change mode, so that the tension exerted on the plastic film 7 and the embryo wires by the driving rollers 601 at two sides of the support plate 101 is reduced, and the compression amount of the elastic pieces 306 at two sides of the dividing knife 204 is restored to a stable state.
It should be noted that: in the shrinking process of the pushing member 402, the shrinkage is based on the compression of the elastic member 306, so that the phenomenon that the efficiency of dividing the plastic film 7 by the dividing knife 204 is reduced due to insufficient tension applied to the plastic film 7 and the embryo wire by the driving rollers 601 on two sides of the support plate 101 caused by overlarge shrinkage of the pushing member 402 is avoided.
It should be noted that: in the process of sucking the expansion member 603 through the air outlet pipe 405, the air in the expansion member 603 enters the inside of the driving roller 601 through the through holes 602 on the driving roller 601 (the driving roller 601 is hollow, as shown in fig. 9, in particular), and then enters the inside of the air outlet pipe 405 through the air outlet holes 406 on the fixed roller 5.
It should be noted that: in this embodiment, two ends of the fixed roller 5 are fixedly connected with the supporting plate 101 respectively, the driving roller 601 is rotatably connected to the middle of the fixed roller 5, the expansion piece 603 is arranged on the outer side of the fixed roller 5, when the plastic film 7 is in extrusion contact with the expansion piece 603, the driving roller 601 rotates along with the running of the plastic film 7, and excessive friction between the plastic film 7 and the expansion piece 603 on the outer surface of the driving roller 601 is avoided, so that the quality of the cut embryo yarn is affected.
It should be noted that: because in the initial state, the electromagnetic rollers 303 positioned at two sides of the dividing knife 204 magnetically clamp the magnetic block 203, when the tension applied to the plastic film 7 and the embryo wire by the driving rollers 601 at two sides of the support plate 101 is increased, the extrusion force applied to the rotating roller 302 by the plastic film 7 and the embryo wire is increased, so that the rotating roller 302 and the electromagnetic rollers 303 move downwards along the moving groove 301, under the influence of the magnetic attraction of the electromagnetic rollers 303 to the magnetic block 203, the electromagnetic rollers 303 synchronously drive the magnetic block 203 to move downwards, and the magnetic block 203 synchronously drive the dividing knife 204 to move downwards, so that when the tension applied to the plastic film 7 by the dividing knife 204 is excessive, the cutting force applied to the plastic film 7 by the dividing knife 204 is excessive, and the dividing quality of the embryo wire is influenced.
When the control system detects that the compression amount of the elastic pieces 306 at two sides of the dividing knife 204 is smaller than the set value (namely, the compression amount is too small), the driving rollers 601 at two sides of the supporting plate 101 exert too small tension on the plastic film 7 and the embryo wires, at this time, the control system controls the pushing pieces 402 on the support 401 to stretch (the pushing pieces 402 comprise electric push rods), in the stretching process of the pushing pieces 402, the extruding pieces 404 are extruded through the extruding plates 403 (the extruding pieces 404 comprise corrugated pipes), so that the gas in the extruding pieces 404 enters the driving rollers 601 through the gas outlet pipes 405 and the gas outlet holes 406, and then enters the expansion pieces 603 through the through holes 602, so that the expansion pieces 603 expand, the diameters of the driving rollers 601 are increased in a phase-changing manner, and the tension exerted on the plastic film 7 and the embryo wires by the driving rollers 601 at two sides of the supporting plate 101 is increased until the compression amount of the elastic pieces 306 at two sides of the dividing knife 204 is restored to a stable state.
It should be noted that: because the electromagnetic rollers 303 positioned at two sides of the separating knife 204 in the initial state magnetically clamp the magnetic blocks 203, when the tension applied by the driving rollers 601 at two sides of the supporting plate 101 to the plastic film 7 and the embryo wires is reduced, the extrusion force applied by the plastic film 7 and the embryo wires to the rotating rollers 302 is reduced, under the elastic restoring force of the elastic piece 306, the elastic piece 306 pushes the electromagnetic rollers 303 to move upwards along the moving grooves 301 through the mounting blocks 304, under the influence of the magnetic attraction of the electromagnetic rollers 303 to the magnetic blocks 203, the electromagnetic rollers 303 synchronously drive the magnetic blocks 203 to move upwards, and the magnetic blocks 203 synchronously drive the separating knife 204 to move upwards, so that the length of the separating knife 204 extending out of the connecting grooves 16 is increased, the separating knife 204 can comprehensively cut the plastic film 7, and the phenomenon of adhesion between the embryo wires is avoided when the plastic film 7 is separated.
It should be noted that: when extrusion plate 403 extrudes extrusion piece 404, the both ends of extrusion plate 403 remove on slide 10 of limiting plate 9, limiting plate 9 restrict extrusion piece 404 in cross slot 8, avoid extrusion plate 403 to extrude extrusion piece 404 when extrusion plate 404, extrusion piece 404 takes place to skew, influences the extrusion effect of extrusion piece 404.
It should be noted that: in the process of stretching the pushing member 402, the stretching amount of the pushing member 402 is based on the compression amount of the elastic member 306, so that the phenomenon that the plastic film 7 and the embryo wire are broken due to overlarge stretching amount of the pushing member 402 and overlarge tension applied to the plastic film 7 and the embryo wire by the driving rollers 601 on two sides of the support plate 101 is avoided.
When the control system detects that the compression amount of the elastic member 306 at the side of the dividing knife 204 close to the extrusion film forming device 12 is smaller than the set value (i.e. the compression amount is too small), and when the compression amount of the elastic member 306 at the side of the dividing knife 204 close to the winding device 15 exceeds the set value (i.e. the compression amount is too large), it indicates that during the long-time use of the dividing knife 204, the edge portion of the dividing knife 204 is worn excessively, so that the plastic film 7 is not divided in time when being divided by the dividing knife 204, and the plastic film 7 is accumulated at the edge portion, so that the extrusion force of the plastic film 7 to the rotating roller 302 at the side close to the extrusion film forming device 12 is reduced, however, because the winding speed of the winding device 15 is unchanged, the extrusion force of the plastic film 7 to the rotating roller 302 at the side close to the winding device 15 is increased (taking fig. 4 as an example, the rotating roller 302 at the left side is located at a high position, and the rotating roller 302 at the right side is located at a low position).
At this time, the control system controls the pushing member 402 close to one side of the winding device 15 to shrink, the pushing member 402 stretches the extrusion member 404 through the extrusion plate 403, so that the gas inside the expansion member 603 is pumped into the extrusion member 404, the diameter of the driving roller 601 close to one side of the winding device 15 is reduced in a phase-changing manner, and the phenomenon that the winding device 15 breaks the embryo wire due to overlarge pulling force of the embryo wire is avoided (taking fig. 7 as an example, the expansion member 603 on the right side is controlled to shrink).
Meanwhile, the pushing member 402 near one side of the extrusion film forming device 12 is controlled to extend, the pushing member 402 extrudes the extrusion member 404 through the extrusion plate 403, so that the expansion member 603 expands, the diameter of the driving roller 601 near one side of the extrusion film forming device 12 is increased in a phase-changing manner, and the phenomenon that the plastic film 7 is accumulated at the dividing knife 204 is avoided (taking fig. 7 as an example, the expansion member 603 on the left side is controlled to expand).
When the control system controls the pushing piece 402 to move, the control system controls the electromagnetic roller 303 on the right side of the dividing roller 102 to be powered off, the control system controls the electromagnetic roller 303 on the left side of the dividing roller 102 to be continuously switched on and off, at the moment, the magnetic block 203 is only affected by the electromagnetic roller 303 on the right side, because the magnetic block 203 is in limited axial sliding connection with the accommodating groove 201, when the electromagnetic roller 303 on the right side is powered on, the electromagnetic roller 303 drives the dividing knife 204 to move upwards through the magnetic block 203, when the electromagnetic roller 303 on the right side is powered off, the magnetic block 203 drives the dividing knife 204 to move downwards under the elastic restoring force of the spring 2024, and the magnetic block 203 drives the dividing knife 204 to continuously move up and down in the continuous power-on and power-off process of the electromagnetic roller 303 on the right side, so that the cutting efficiency of the dividing knife 204 on the plastic film 7 is improved, and the plastic film 7 is prevented from accumulating on the right side of the dividing knife 204.
It should be noted that: in the initial state, the electromagnetic rollers 303 on both sides of the dividing roller 102 are at the same height as the magnetic block 203, and the spring 2024 is in a stable state (i.e., not compressed nor elongated); when the electromagnetic roller 303 moves upward, the magnetic block 203 moves upward simultaneously, and the spring 2024 is in a stretched state; when the electromagnetic roller 303 moves downward, the magnetic block 203 moves downward simultaneously, and the spring 2024 is in a compressed state.
When the magnetic block 203 drives the dividing knife 204 to continuously move up and down, the magnetic block 203 synchronously drives the sealing disc 2022 to move up and down in the fixed cylinder 2021 through the ejector rod 2023, external air is pumped into the fixed cylinder 2021 through the air pumping holes 2025 when the sealing disc 2022 moves down, the air pumped into the fixed cylinder 2021 is extruded into the air pumping pipeline 2026 when the sealing disc 2022 moves up, finally the air is sprayed out from the air exhausting holes 2027, and impurities adhered to the surface of the dividing knife 204 are cleaned by the sprayed air, so that the impurities are prevented from adhering to the surface of the dividing knife 204 to influence the dividing quality of embryo wires.
It should be noted that: the check valve provided inside the air suction hole 2025 is not in and out only; the check valve provided inside the exhaust pipe 2026 is not taken in.
According to the invention, the elastic piece 306 and the expansion piece 603 are arranged, after the compression amount of the elastic piece 306 exceeds a set value, the driving component 4 is controlled to enable the expansion piece 603 to shrink, and the diameter of the driving roller 601 is reduced in a phase-changing manner, so that the tension applied to the plastic film 7 and the embryo wire by the driving rollers 601 on two sides of the support plate 101 is reduced; after detecting that the compression amount of the elastic piece 306 is smaller than a set value, controlling the driving assembly 4 to expand the expansion piece 603, and increasing the diameter of the driving roller 601 in a phase-changing manner, so that the tension applied to the plastic film 7 and the embryo wire by the driving rollers 601 on two sides of the support plate 101 is increased; thereby ensuring the cutting efficiency of the parting knife 204 to the embryo thread.
According to the invention, by arranging the electromagnetic roller 303 and the magnetic block 203, when the control system detects that the compression amount of the left elastic piece 306 is smaller than a set value and the compression amount of the right elastic piece 306 exceeds the set value, the electromagnetic roller 303 on the right side of the dividing roller 102 is controlled to be powered off, the control system controls the electromagnetic roller 303 on the left side of the dividing roller 102 to be continuously powered on and off, and under the influence of magnetic attraction, the magnetic block 203 drives the dividing knife 204 to continuously move up and down, so that the cutting efficiency of the dividing knife 204 on the plastic film 7 is improved, and the plastic film 7 is prevented from being accumulated on the right side of the dividing knife 204.

When the control system detects that the compression amount of the elastic pieces 306 at the two sides of the dividing knife 204 is in a stable state, the tension applied by the driving rollers 601 at the two sides of the support plate 101 to the plastic film 7 and the embryo wires is in a stable state, and the device is in a normal running state.
At this time, the control system controls the first electromagnetic control valve in the air outlet pipe 405 to be closed, the extrusion part 404 cannot be communicated with the expansion piece 603 through the air outlet pipe 405, then the second electromagnetic control valve in the inclined hole in the extrusion part 404 is controlled to be started, the extrusion part 404 is communicated with the outside air through the inclined hole, the extrusion part 402 is controlled to stretch out and draw back continuously, the extrusion part 404 is synchronously driven to stretch out and draw back, the outside air is pumped into the extrusion part 404 when the extrusion part 404 stretches out, and when the extrusion part 404 stretches back, the air in the extrusion part 404 is impacted onto the plastic film 7 through the inclined hole, so that the plastic film 7 vibrates, impurities adhered on the plastic film 7 can drop with water drops, and the segmentation quality of the segmentation knife 204 is improved.
When tension adjustment is needed, the first electromagnetic control valve is controlled to be started, and the second electromagnetic control valve is closed, so that the pushing piece 402 can adjust the outer diameter of the driving roller 601 through the extrusion piece 404 and the air outlet pipe 405.
