Description

Technical Field

[0001] This utility model relates to a winding mechanism, and more particularly to a slitting machine edge material winding device. Background Technology

[0002] Extrusion sheet machines extrude sheets through a die head. The extruded sheets often have problems such as waste accumulation, bending, wrinkling, and folding on both sides. Therefore, before winding the sheets, it is necessary to use an edge trimming device to remove the excess edge material on both sides of the sheets.

[0003] In traditional edge-cutting devices, the cut sheet scrap is usually discarded directly. However, sheet scrap is typically in strips and quite long. Allowing it to be piled up haphazardly during cutting not only takes up a lot of space but also makes it difficult to manage. Therefore, sheet scrap needs to be wound up after cutting. However, because the scrap is usually narrow, not only are special-width winding shafts required, but also limiting plates on both sides of each winding shaft are needed to prevent the narrow rolls from unraveling. Furthermore, unloading and storing too many small rolls is inconvenient. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an edge material winding device for a slitting machine. This edge material winding device can wind the edge material into a wide roll, and can keep the width of each position close during winding, which is convenient for unloading and storage.

[0005] To solve the above technical problems, the following technical solution is adopted:

[0006] An edge material winding device for a slitting machine includes a frame, a guiding mechanism, a winding shaft, a winding shaft drive device capable of driving the winding shaft to rotate, and a control device. The guiding mechanism, the winding shaft drive device, and the control device are respectively mounted on the frame. The winding shaft is rotatably mounted on the frame. The signal input terminal of the winding shaft drive device is electrically connected to the corresponding signal output terminal of the control device. The device is characterized by further including an edge material guiding mechanism and a speed regulating mechanism. The edge material guiding mechanism includes a translation seat, a translation drive device capable of driving the translation seat to reciprocate left and right, and a guide member. The translation drive device and the speed regulating mechanism are respectively mounted on the frame. The guide member is mounted on the translation seat and extends from front to back along the winding direction, with both ends of the guide member corresponding to the positions of the guiding mechanism and the winding shaft. The signal input terminal of the control device is electrically connected to the signal output terminal of the speed regulating mechanism, and the signal input terminal of the translation drive device is electrically connected to the corresponding signal output terminal of the control device.

[0007] In the aforementioned edge material winding device, the width of the winding shaft is greater than the width of the edge material. During use, the cut edge material is fed into the edge material winding device and first guided by a guiding mechanism, then wound onto the winding shaft by guides on a translation seat. During winding, a translation drive device drives the translation seat to reciprocate, allowing the edge material to spirally wind around the winding shaft along its width direction. When it reaches the end of the winding shaft, it returns, achieving layer-by-layer winding until the narrow edge material is wound into a wide roll. During winding, if the winding speed is greater than or less than the unwinding speed, a speed regulating mechanism sends a signal to a control device. The control device then controls the winding shaft drive device to increase / decrease the speed of the winding shaft rotation accordingly, and simultaneously controls the translation drive device to increase / decrease the speed of the translation seat translation until the winding speed matches the unwinding speed. This edge material winding device can collect edge materials into rolls and evenly wind them onto the winding shaft during winding. It can wind longer edge materials into wider rolls at once, making them easier to store and less likely to unravel. At the same time, it can also adjust the translation speed of the translation seat to ensure that the edge material is always evenly wound on the winding shaft (i.e., the edges of adjacent turns of edge material on the winding shaft always remain in contact), ensuring stable winding.

[0008] The aforementioned front and back directions are determined based on the winding direction. During winding, the position that the edge material passes through first is called the front, and the position that it passes through last is called the back.

[0009] In a preferred embodiment, the translation drive device includes a guide rod, a rotation drive device capable of driving the guide rod to rotate, and a stroke control rod. The rotation drive device and the stroke control rod are respectively mounted on the frame, and adjustable nuts are provided at both ends of the stroke control rod. The guide rod is rotatably mounted on the frame, and the guide rod is parallel to the stroke control rod. The translation base is a guide rod cable guide, which is movably mounted on the guide rod. The guide rod cable guide is provided with a stop that matches the adjustable nut. By using the guide rod cable guide as the translation base, the translation drive device does not need to frequently change the drive direction. The guide rod cable guide can automatically change its moving direction when it moves to the end of the guide rod and the stop contacts the adjustable nut. Furthermore, different widths of winding can be achieved by adjusting the position of the adjustable nut.

[0010] In a further preferred embodiment, the take-up shaft drive device includes a drive motor, a drive pulley, a first driven pulley, and a belt. The drive motor is mounted on the frame, the drive pulley is mounted on the power output shaft of the drive motor, and the first driven pulley is mounted on the take-up shaft. The rotation drive device is a second driven pulley, which is mounted on the guide rod. The belt is tensioned between the drive pulley, the first driven pulley, and the second driven pulley. The signal output terminal of the control device is electrically connected to the signal input terminal of the drive motor. Because the translation seat uses a guide rod cable guide, the guide rod does not need to frequently change its rotation direction. Therefore, the guide rod and the take-up shaft can be driven by the same drive motor, which facilitates uniform winding and take-up speeds and allows for unified speed adjustment without separate control, effectively reducing control difficulty.

[0011] In a preferred embodiment, the speed regulating mechanism includes a rotating shaft, a swing arm, a floating roller, and an angle detection component. The rotating shaft is rotatably mounted on the frame, one end of the swing arm is mounted on the rotating shaft, and the floating roller is rotatably mounted on the other end of the swing arm, with the floating roller positioned in front of the translation seat along the conveying direction. The angle detection component is mounted on the frame, and the rotating shaft is drively connected to the angle detection component. The signal output terminal of the angle detection component is electrically connected to the corresponding signal input terminal of the control device. When the edge material is fed into the edge material winding device by the edge material unwinding device, it first passes through the floating roller and the guiding mechanism, then through the guide on the translation seat, and finally is wound up by the winding shaft. When the winding speed matches the unwinding speed, the floating roller is in the normal tension position. When the winding speed is greater than or less than the unwinding speed, the fed edge material will be tightened / unwinded. At this time, the floating roller will also be pulled / dropped accordingly, driving the swing arm to swing and causing the shaft to rotate. The angle detection component detects the rotation of the shaft and sends a detection signal to the control device according to the detected rotation angle. The control device controls the winding shaft drive device and the translation drive device to adjust the winding speed and translation speed respectively according to the detection signal, so that the winding speed matches the unwinding speed, thereby restoring the tension of the edge material during feeding to normal.

[0012] In a further preferred embodiment, the angle detection component includes a potentiometer mounted on the frame. The rotating shaft is connected to the rotating shaft of the potentiometer via a transmission connection, and the signal output terminal of the potentiometer is electrically connected to the corresponding signal input terminal of the control device. When the rotating shaft rotates, it drives the rotating shaft of the potentiometer to rotate accordingly. Based on the magnitude of the rotation angle, the potentiometer sends the detected signal to the control device, enabling the control device to adjust the corresponding speed according to the detection signal, achieving stepless speed regulation and further ensuring stable winding.

[0013] In a further preferred embodiment, the angle detection component further includes a first gear and a second gear. The first gear is mounted on the rotating shaft, and the second gear is mounted on the rotating shaft of the potentiometer. The first gear meshes with the second gear, and the diameter of the first gear is larger than the diameter of the second gear. When the rotating shaft rotates, it drives the first gear to rotate, which in turn causes the rotating shaft of the potentiometer to rotate. By setting the diameter of the first gear to be larger than that of the second gear, even if the rotating shaft rotates at a small angle, the potentiometer can quickly sense this and send a signal to the control device, allowing the control device to make timely adjustments.

[0014] In a further preferred embodiment, the first gear is a sector gear.

[0015] In a further preferred embodiment, the speed regulating mechanism further includes a telescopic support member, one end of which is hinged to the frame, and the other end of which is hinged to the swing arm. With this configuration, when the tension of the edge material returns to normal, the swing arm, under the action of the telescopic support member, can drive the floating roller to return to its normal tension position.

[0016] In a further preferred embodiment, the telescopic support member employs a gas spring or a single-acting spring press-out cylinder. When winding is proceeding normally, the tension provided by the edge material during conveying is the same as the pushing force of the gas spring or single-acting spring press-out cylinder; when the edge material is tightened / untightened, the tension of the edge material is greater than / less than the pushing force of the gas spring or single-acting spring press-out cylinder until the speed adjustment returns to normal. At this point, the gas spring or single-acting spring press-out cylinder can drive the floating roller to return to the normal tension position via the swing arm.

[0017] In a preferred embodiment, the guide includes two guide rods arranged side by side. The front ends of the guide rods are mounted on the translation seat, and the rear ends of the guide rods extend to the outside of the take-up shaft. Typically, the distance between the two guide rods matches the width of the edge material, allowing the two sides of the edge material to rest on the two guide rods. By setting the guide rods, the edge material can be better guided to the corresponding position on the take-up shaft, making the winding process more stable and preventing excessive protrusion of any part of the wound material.

[0018] In a further preferred embodiment, the rear ends of the two guide rods are provided with extensions that gradually extend to both sides from front to back. When the edge material passes the rear ends of the guide rods, the edge material can be caught in the gap between the two extensions, ensuring that it will not shift during the winding process and further improving the stability of the winding.

[0019] In a preferred embodiment, the guiding mechanism includes multiple guide rollers, each rotatably mounted on the frame, and arranged sequentially from front to back along the conveying direction of the edge material. After being guided by the guide rollers, the edge material passes through a guide member and is then wound up by a take-up shaft.

[0020] The aforementioned control devices typically employ microcomputer controllers, but PID controllers, microcontrollers, PLC controllers, and their peripheral circuits can also be used.

[0021] The beneficial effects of this utility model are as follows: this edge material winding device can wind edge material into a wide roll, and can keep the width of each position close during winding, which is convenient for unloading and storage. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0027] like Figure 1-4 The edge material winding device of a slitting machine shown includes a frame 1, a guide mechanism 2, a winding shaft 3, a winding shaft drive device 4 capable of driving the winding shaft 3 to rotate, an edge material guiding mechanism 5, a speed regulating mechanism 6, and a control device (not shown in the figure). The guide mechanism 2, the winding shaft drive device 4, and the control device are respectively mounted on the frame 1, and the winding shaft 3 is rotatably mounted on the frame 1. The edge material guiding mechanism 5 includes a translation seat 501, a translation drive device 502 capable of driving the translation seat 501 to reciprocate left and right, and... The guide 503, the translation drive device 502, and the speed regulating mechanism 6 are respectively mounted on the frame 1. The guide 503 is mounted on the translation seat 501. The guide 503 extends from front to back along the winding direction, and the two ends of the guide 503 correspond to the positions of the guide mechanism 2 and the take-up shaft 3, respectively. The signal input terminal of the control device is electrically connected to the signal output terminal of the speed regulating mechanism 6. The signal input terminals of the take-up shaft drive device 4 and the translation drive device 502 are respectively electrically connected to the corresponding signal output terminals of the control device.

[0028] In the aforementioned edge material winding device, the width of the winding shaft 3 is greater than the width of the edge material. During use, after the cut edge material is fed into the edge material winding device, it is first guided and conveyed by the guiding mechanism 2, and then wound onto the winding shaft 3 by the guide member 503 on the translation seat 501. During winding, the translation drive device 502 drives the translation seat 501 to reciprocate, allowing the edge material to spirally wind around the winding shaft 3 along its width direction. When it reaches the end of the winding shaft 3, it can return, thus achieving layer-by-layer winding until the narrow edge material is wound into a wide roll. During the winding process, if the winding speed is greater than or less than the unwinding speed, the speed regulating mechanism 6 sends a signal to the control device, which controls the winding shaft drive device 4 to increase / decrease the rotation speed of the winding shaft 3 accordingly. Simultaneously, it controls the translation drive device 502 to increase / decrease the translation speed of the translation seat 501 until the winding speed matches the unwinding speed. This edge material winding device can collect edge materials into rolls and evenly wind them onto the winding shaft 3 during winding. This allows the winding shaft 3 to wind up edge materials of longer lengths at once and to wind them into wider rolls, which are convenient for subsequent storage and less likely to unravel. At the same time, it can also adjust the translation speed of the translation seat 501, so that the edge material can always be evenly wound on the winding shaft 3 (that is, the edges of adjacent turns of edge material on the winding shaft 3 can always be kept in contact), ensuring stable winding.

[0029] The aforementioned front and back directions are determined based on the winding direction. During winding, the position that the edge material passes through first is called the front, and the position that it passes through last is called the back.

[0030] The translation drive device 502 includes a guide rod 5021, a rotation drive device 5022 capable of driving the guide rod 5021 to rotate, and a stroke control rod 5023. The rotation drive device 5022 and the stroke control rod 5023 are respectively mounted on the frame 1. Adjustable nuts (not shown in the figure) are provided at both ends of the stroke control rod 5023. The guide rod 5021 is rotatably mounted on the frame 1, and the guide rod 5021 is parallel to the stroke control rod 5023. The translation seat 501 is a guide rod cable guide, which is slidably mounted on the guide rod 5021. The guide rod cable guide is provided with a stop (not shown in the figure) that matches the adjustable nut. By using the guide rod cable guide as the translation seat 501, the translation drive device 502 does not need to frequently change the drive direction. The guide rod cable guide can automatically change the moving direction when it moves to the end of the guide rod 5021 and the stop contacts the adjustable nut. Furthermore, the winding needs of different widths can be met by adjusting the position of the adjustable nut.

[0031] The take-up shaft drive device 4 includes a drive motor 401, a drive pulley 402, a first driven pulley 403, and a belt 404. The drive motor 401 is mounted on the frame 1, the drive pulley 402 is mounted on the power output shaft of the drive motor 401, and the first driven pulley 403 is mounted on the take-up shaft 3. The rotation drive device 5022 is a second driven pulley, which is mounted on the guide rod 5021. The belt 404 is tensioned between the drive pulley 402, the first driven pulley 403, and the second driven pulley. The signal output terminal of the control device is electrically connected to the signal input terminal of the drive motor 401. Since the translation seat 501 uses a guide rod winding device, the guide rod 5021 does not need to frequently change its rotation direction. Therefore, the guide rod 5021 and the take-up shaft 3 can be driven by the same drive motor 401, which makes it easier to unify the winding speed and also allows for unified speed adjustment without separate control, effectively reducing the control difficulty.

[0032] The speed regulating mechanism 6 includes a rotating shaft 601, a swing arm 602, a floating roller 603, and an angle detection component 604. The rotating shaft 601 is rotatably mounted on the frame 1. One end of the swing arm 602 is mounted on the rotating shaft 601, and the floating roller 603 is rotatably mounted on the other end of the swing arm 602. The floating roller 603 is positioned in front of the translation seat 501 along the conveying direction. The angle detection component 604 is mounted on the frame 1, and the rotating shaft 601 is connected to the angle detection component 604 via a transmission connection. The signal output terminal of the angle detection component 604 is electrically connected to the corresponding signal input terminal of the control device. When the edge material is fed into the edge material winding device by the edge material unwinding device, it first passes through the floating roller 603 and the guide mechanism 2, then through the guide member 503 on the translation seat 501, and finally is wound up by the winding shaft 3. When the winding speed matches the unwinding speed, the floating roller 603 is in the normal tension position. When the winding speed is greater than or less than the unwinding speed, the fed edge material will be tightened / unwinded. At this time, the floating roller 603 will also be pulled / dropped accordingly, and the swing arm 602 will swing, causing the rotating shaft 601 to rotate. The angle detection component 604 detects the rotation of the rotating shaft 601 and sends the detection signal to the control device according to the detected rotation angle. The control device controls the winding shaft drive device 4 and the translation drive device 502 to adjust the winding speed and translation speed respectively according to the detection signal, so that the winding speed matches the unwinding speed, thereby restoring the tension of the edge material during conveying to normal.

[0033] The angle detection component 604 includes a potentiometer 6041, which is mounted on the frame 1. A rotating shaft 601 is connected to the rotating shaft 601 of the potentiometer 6041, and the signal output terminal of the potentiometer 6041 is electrically connected to the corresponding signal input terminal of the control device. When the rotating shaft 601 rotates, it drives the rotating shaft 601 of the potentiometer 6041 to rotate accordingly. Based on the magnitude of the rotation angle, the potentiometer 6041 sends the detected signal to the control device, enabling the control device to adjust the corresponding speed according to the detection signal, achieving stepless speed regulation and further ensuring stable winding.

[0034] The angle detection component 604 also includes a first gear 6042 and a second gear 6043. The first gear 6042 is mounted on the rotating shaft 601, and the second gear 6043 is mounted on the rotating shaft 601 of the potentiometer 6041. The first gear 6042 and the second gear 6043 mesh, and the diameter of the first gear 6042 is larger than the diameter of the second gear 6043. When the rotating shaft 601 rotates, it drives the first gear 6042 to rotate, and through the second gear 6043, it causes the rotating shaft 601 of the potentiometer 6041 to rotate accordingly. By setting the diameter of the first gear 6042 to be larger than that of the second gear 6043, even if the rotating shaft 601 rotates at a small angle, the potentiometer 6041 can quickly sense and send a signal to the control device, enabling the control device to make timely adjustments.

[0035] The first gear, 6042, is a sector gear.

[0036] The speed regulating mechanism 6 also includes a telescopic support 605, one end of which is hinged to the frame 1, and the other end of which is hinged to the swing arm 602. With this arrangement, when the tension of the edge material returns to normal, the swing arm 602 can drive the floating roller 603 to return to the normal tension position under the action of the telescopic support 605.

[0037] The telescopic support 605 uses a gas spring or a single-acting spring press-out cylinder. When winding is in normal operation, the tension provided by the edge material during conveying is the same as the pushing force of the gas spring or single-acting spring press-out cylinder; when the edge material is tightened / untightened, the tension of the edge material is greater than / less than the pushing force of the gas spring or single-acting spring press-out cylinder until the speed adjustment returns to normal. At this time, the gas spring or single-acting spring press-out cylinder can drive the floating roller 603 to return to the normal tension position through the swing arm 602.

[0038] The guide 503 includes two guide rods 5031 arranged side by side. The front ends of the guide rods 5031 are mounted on the translation seat 501, and the rear ends of the guide rods 5031 extend to the outside of the take-up shaft 3. Typically, the distance between the two guide rods 5031 matches the width of the edge material, allowing the two sides of the edge material to rest on the two guide rods 5031. By setting the guide rods 5031, the edge material can be better guided to the corresponding position on the take-up shaft 3, making the winding process more stable and preventing excessive protrusion of any part of the wound material.

[0039] The rear ends of the two guide rods 5031 are provided with extensions 5032 that gradually extend from front to back to both sides. When the edge material passes the rear end of the guide rods 5031, the edge material can be stuck in the gap between the two extensions 5032, ensuring that it will not deviate during the winding process and further improving the stability of the winding.

[0040] The guiding mechanism 2 includes multiple guide rollers 201, each of which is rotatably mounted on the frame 1, and the guide rollers 201 are arranged sequentially from front to back along the conveying direction of the edge material. After being guided by the guide rollers 201, the edge material passes through the guide member 503 and is then wound up by the take-up shaft 3.

[0041] The aforementioned control device employs a microcomputer controller.
