Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, and in particular to a winding device for an automatic fabric slitting machine. Background Technology

[0002] In the textile operation process, after the knitting machine finishes weaving the fabric, the fabric must be pulled to a fabric winding machine. The fabric is then wound onto a take-up roller. After the fabric is wound, it is cut and then the take-up roller is removed and transported to the storage area.

[0003] Traditional fabric rolling methods require workers to manually roll the fabric end, which passes between two guide rollers, onto the take-up roller before starting to roll the fabric, making the fabric taut. This preparation work takes a lot of time and reduces production efficiency. At the same time, the fabric end only relies on friction to wrap around the take-up roller, making it easy to fall off during the rolling process. If glue is used to fix the fabric end, it requires an additional glue application process, making the operation more cumbersome, and the parts will contaminate the fabric.

[0004] In view of this, the inventors of this case conducted in-depth research on the above-mentioned problems, which led to the creation of this case. Utility Model Content

[0005] The purpose of this utility model is to provide a winding device for an automatic fabric slitting machine that is simple in structure, easy to operate, and can effectively fix the fabric head and prevent the fabric from slipping off the winding roller.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: A winding device for an automatic fabric winding and splitting machine includes a frame, a winding roller for winding fabric, two guide rollers for driving the winding roller to rotate, and an auxiliary component for fixing the fabric head on the winding roller. The winding roller is disposed above and between the two guide rollers. The winding roller has a slot with a strip-shaped opening along its axial direction. The auxiliary component is disposed directly below the two guide rollers. The auxiliary component includes a mounting base fixedly mounted on the frame, an insert plate movably disposed on the mounting base, and a first drive unit for driving the insert plate to move towards or away from the slot. The insert plate is inserted into the interior of the slot, and the size of the insert plate is adapted to the slot so that the first drive unit drives the insert plate to insert the fabric head into the slot.

[0007] Furthermore, the insert plate is connected to the mounting base via a connector. One end of the connector is hinged to the mounting base via a first pin, and the other end is connected to the insert plate. The connector has an oblong hole on the side near the first drive unit. The first drive unit is a first cylinder, and the piston rod of the first cylinder is movably disposed in the oblong hole so that the connector can be rotated along the first pin by driving the piston rod of the first cylinder to extend and retract.

[0008] Furthermore, the waist-shaped hole has a first positioning point for the connector to rotate so that the insert plate is close to the slot and a second positioning point for the connector to rotate so that the insert plate is away from the slot. When the insert plate is close to the slot, the first positioning point is located at the upper end of the waist-shaped groove and the second positioning point is located at the lower end of the waist-shaped groove. The piston rod of the first cylinder can move back and forth between the first positioning point and the second positioning point.

[0009] Furthermore, it also includes a moving component that drives the auxiliary component to move along the length direction of the slot. The moving component includes a linear guide arranged along the axial direction of the take-up roller, a slider movably arranged on the linear guide, and a second driving unit that drives the slider to move along the length direction of the linear guide. The mounting base is fixedly arranged on the second driving unit.

[0010] Furthermore, each end of the linear guide is provided with a limiting member to restrict the slider from sliding out of the linear guide. The slider is disposed between the two limiting members and can move back and forth along the length direction of the linear guide. The second driving unit is a rodless cylinder.

[0011] Furthermore, it also includes a sensor assembly for detecting the return of the slot to center. The sensor assembly includes a mounting base on the frame, a sensor body fixedly mounted on the mounting base, and a sensing head mounted on one end of the take-up roller. The sensing head is positioned relative to the sensor body. Both the sensor body and the sensing head are cylindrical structures, and their axes are both arranged in the vertical direction.

[0012] Furthermore, the insert plate is rotatably mounted on the connector via a second pin.

[0013] Furthermore, the insert plate is a silicone insert plate.

[0014] Furthermore, the inner surface of the slot is provided with a friction layer to enhance friction.

[0015] By adopting the aforementioned design scheme, the beneficial effects of this utility model are as follows: the fabric end is inserted into the slot by inserting the insert plate, so that the end of the fabric is initially rolled up and fixed in the slot of the take-up roller. The fabric will not loosen when it is rolled up, which solves the problem that the fabric end needs to be held down by hand until the fabric can be rolled up onto the take-up device before it can be released. This reduces the difficulty of operation for workers and makes it easier for workers to use. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figures 1 to 3 :

[0022] An automatic fabric rolling and slitting machine's winding device includes a frame 1, a winding roller 2 for winding the fabric, two guide rollers 3 for driving the winding roller 2 to rotate, and an auxiliary component 4 for fixing the fabric head onto the winding roller 2. The winding roller 2 is positioned above and between the two guide rollers 3. It is worth noting that the fabric rolling and slitting machine in this embodiment can be a fabric rolling machine with a pre-release function, as described in Chinese Utility Model Patent (Announcement No.: CN216615035U). This utility model is located at the front end of the cutting mechanism in the aforementioned patent, and the remaining structures are identical to the components in the aforementioned patent, and will not be described in detail here.

[0023] The take-up roller 2 has a slot 21 with a strip shape on its upper side along its axial direction.

[0024] The auxiliary component 4 is positioned directly below the two guide rollers 3. The auxiliary component 4 includes a mounting base 41 fixedly mounted on the frame 1, an insert plate 42 movably mounted on the mounting base 41, and a first drive unit 43 that drives the insert plate 42 to move towards or away from the slot 21. The insert plate 42 is inserted into the slot 21, and its thickness is adapted to the width of the slot 21, so that the first drive unit 43 drives the insert plate 42 to insert the fabric head into the slot 21. Specifically, the first drive unit 43 is a first cylinder. Preferably, the inner surface of the slot 21 is provided with a friction layer to enhance friction, thereby further strengthening the adhesion between the fabric head and the take-up roller 2 when the fabric head is placed in the slot 21.

[0025] Furthermore, the insert plate 42 is connected to the mounting base 41 via a connector 44. One end of the connector 44 is hinged to the mounting base 41 via a first pin 442, and the other end is connected to the insert plate 42. The connector 44 has a waist-shaped hole 441 on the side near the first cylinder. The piston rod of the first cylinder is movably disposed in the waist-shaped hole 441, so that by driving the piston rod of the first cylinder to extend and retract, the connector 44 can be rotated along the first pin 442. Specifically, the insert plate 42 is a silicone insert plate 42, and the friction layer is a silicone friction layer to prevent the fabric head from being damaged when the insert plate 42 inserts the fabric head into the slot 21.

[0026] Furthermore, the waist-shaped hole 441 has a first positioning point for the connector 44 to rotate so that the insert plate 42 is close to the slot 21 and a second positioning point for the connector 44 to rotate so that the insert plate 42 is away from the slot 21. When the insert plate 42 is close to the slot 21, the first positioning point is located at the upper end of the waist-shaped hole 441 and the second positioning point is located at the lower end of the waist-shaped hole 441. The piston rod of the first cylinder can move back and forth between the first positioning point and the second positioning point.

[0027] This application also includes a moving component 5 that drives the auxiliary component 4 to move along the length of the slot 21. The moving component 5 includes a linear guide 51 arranged along the axis of the take-up roller 2, a slider 52 movably arranged on the linear guide 51, and a second drive unit 53 that drives the slider 52 to move along the length of the linear guide 51. The mounting base 41 is fixedly arranged on the second drive unit 53. Specifically, the second drive unit 53 is a rodless cylinder, which saves space for equipment integration.

[0028] Furthermore, the insert plate 42 is rotatably mounted on the connector 44 via a second pin 443. When the moving component 5 drives the insert plate 42 mounted thereon to move along the slot 21, the insert plate 42, which is rotatable along the second pin 443, further prevents the fabric head from being damaged when inserted into the slot 21.

[0029] Furthermore, each end of the linear guide 51 is provided with a limiting member 511 to restrict the slider 52 from sliding out of the linear guide 51. The slider 52 is located between the two limiting members 511 and can move back and forth along the length direction of the linear guide 51.

[0030] This application also includes a sensor assembly 6 for detecting the return of slot 21 to center. The sensor assembly 6 includes a fixed base 61 mounted on the frame 1, a sensor 62 fixedly mounted on the fixed base 61, and a sensing head 63 mounted on one end of the take-up roller 2. The sensing head 63 is positioned opposite the sensor 62. Both the sensor 62 and the sensing head 63 are cylindrical structures, and their axes are both vertically oriented. When the take-up roller 2 rotates to the point where slot 21 is facing downwards and returning to center, the corresponding sensing head 63 is opposite the sensor 62. At this time, the sensing head 63 touches the sensor 62, causing each sensor 62 to generate a return signal for the take-up roller 2 and send the signal to the control unit. The control unit is responsible for converting and processing the signal and sending the processing result to the auxiliary component 4 and the moving component 5.

[0031] Working principle: In use, the fabric head is positioned between the two guide rollers 3, and the two guide rollers 3 are driven to rotate, causing the take-up roller 2 and the fabric head positioned between the two guide rollers 3 to rotate together. When the take-up roller 2 rotates to the point where the slot 21 faces downward (at this time, the touch sensor 62 of the sensing head 63 causes each sensor 62 to generate a return signal for the take-up roller 2 and send the signal to the control unit); then the first drive unit 43 drives the piston rod to extend and retract, causing the connecting piece 44 to rotate along the first pin shaft 442, so that the insert plate 42 drives the fabric head to insert into the slot 21; then the second drive unit 43 drives the piston rod to extend and retract, causing the connecting piece 44 to rotate along the first pin shaft 442, so that the insert plate 42 drives the fabric head to insert into the slot 21; then the second drive unit 43 drives the fabric head to rotate. Unit 53 drives the auxiliary component 4 (specifically the working insert plate 42) set on the slider 52 to move along the length direction of the rail 51, that is, to gradually insert the fabric head into the slot 21; when the fabric head is completely inserted into the slot 21, the first drive unit 43 drives the piston rod to extend and retract, causing the connector 44 to rotate along the first pin shaft 442, so that the insert plate 42 rotates away from the slot 21, that is, to complete the stable fixation between the fabric head and the take-up roller 2, and then drives the two guide rollers 3 to rotate, and then the rotating take-up roller 2 will roll up the fabric to achieve the take-up of the fabric.

[0032] This invention inserts the fabric end into the slot 21 through the insert plate 42, so that the end of the fabric is initially rolled up and fixed in the slot 21 of the winding roller 2. The fabric will not loosen during winding, which solves the problem that the fabric end needs to be held down by hand until the fabric can be rolled up onto the winding device before it can be released. This reduces the difficulty of operation for workers and makes it easier for workers to use.
