Description

Technical Field

[0001] This invention relates to the field of fabric winding technology, and more particularly to a winding device for industrial fabrics. Background Technology

[0002] In the textile and related industries, fabric winding is a crucial process that directly affects the quality of the finished product and has a decisive impact on the overall efficiency of the production line. However, current fabric winding processes often employ a free winding method. In this method, the winding rollers are subjected to the weight of the fabric during rotation, causing the wound fabric to often droop and bend, resulting in wrinkles and a loose fabric roll. This loose fabric roll is not only unfavorable for storage and transportation.

[0003] Furthermore, securing the fabric ends typically relies on manual operation, which has significant limitations. Due to the lack of precision and speed in manual operation, the secured fabric may not achieve the required stability, potentially leading to loosening or misalignment during subsequent winding. These issues not only affect the final product quality but can also result in material waste and increased maintenance costs.

[0004] To address the aforementioned issues, we propose a winding device for industrial fabrics, aiming to solve these problems and improve the stability and efficiency of the overall winding process. Summary of the Invention

The device uses a three-dimensional block to ensure the sliding shell fits tightly against the adjacent core, preventing slippage between the core and adjacent take-up rollers during winding and thus improving winding stability. A fixing bar limits the third sliding frame, adjusting the clamping force between the core and adjacent rotating rollers on the fabric, ensuring the wound fabric roll remains regular. Driven by a motor, the positions of the two take-up rollers are exchanged, and the corresponding fixing frame rotates the adjacent sliding block, causing the fabric to wind onto another core. This automatic replacement of the core for winding the fabric further improves the device's winding efficiency. Attached Figure Description

[0053] To more clearly illustrate the technical solutions of the embodiments of the present invention, the accompanying drawings of the embodiments will be briefly described below. Obviously, the drawings described below only relate to some embodiments of the present invention and are not intended to limit the present invention.

[0054] Example 1: A winding device for industrial fabrics, referring to... Figures 1-5As shown, it includes: a support 1, on which a first rotating frame 12 is provided; a rotating sleeve 13, rotatably mounted on the support 1, a rotating roller 14 rotatably mounted between the rotating sleeve 13 and the first rotating frame 12, the rotating roller 14 being provided with a rotating shell 15, a plurality of centrally symmetrically distributed first sliding frames 16 being slidably mounted on the rotating shell 15, a plurality of centrally symmetrically distributed second sliding frames 17 being slidably mounted on the first rotating frame 12, a take-up roller 18 rotatably mounted between the first sliding frame 16 and the adjacent second sliding frame 17, the take-up roller 18 being detachably mounted with a core 181; a drive unit 191, mounted on the support 1, the drive unit 191 being used to drive the rotating sleeve 13 to rotate, the plurality of take-up rollers 18 being transmitted to the rotating sleeve 13 through a transmission unit 192, the take-up roller 18 being provided with a locking mechanism for pressing adjacent cores 181, and the first sliding frame 16 being provided with a limiting mechanism for controlling the intermittent movement of adjacent take-up rollers 18.

[0055] In the above scheme, the drive unit 191 consists of a motor and two gears. The motor is fixed to the bracket 1 via a support. Gears are fixed to the output shaft of the motor and the left side of the rotating sleeve 13, and the two gears mesh with each other. The transmission unit 192 consists of two sprockets, a chain, and a tension wheel (the sprockets and chain in the attached figure are schematic drawings). The tension wheel is used to adapt to the power transmission between the take-up roller 18 and the rotating sleeve 13 after the first sliding frame 16 drives the take-up roller 18 to move. The bracket 1 is equipped with a control module (not shown in the figure) that is electrically connected to the electrical components of this device. The rotating roller 14 There is rotational damping between the second sliding frame 17 and the first rotating frame 12. The end of the second sliding frame 17 away from the first rotating frame 12 is set as a gripper. The gripper on the second sliding frame 17 is controlled to be in an open or closed state by a limit pin. The gripper of the second sliding frame 17 grips the take-up roller 18 to rotate, so that the take-up roller 18 can rotate smoothly to take up the fabric. After the core 181 on the take-up roller 18 has finished taking up the fabric, the operator pulls out the limit pin at the gripper on the second sliding frame 17 to release the gripper on the adjacent take-up roller 18. Then the core 181 and the fabric are taken off.

[0056] Reference Figures 2-5 As shown, a chamber is provided in the middle of the take-up roller 18, and multiple rectangular holes are provided on the side wall of the take-up roller 18. Multiple through holes are provided on the core 181. The first sliding frame 16 is provided with a first air guide hole that communicates with the upper chamber of the adjacent take-up roller 18. The rotating roller 14 is provided with a second air guide hole that communicates with the first air guide hole on the first sliding frame 16. The rotating roller 14 is rotatably provided with a guide tube 19 that communicates with the second air guide hole on it, which is used to guide the flow of gas so that the fabric adheres to the core 181. The bracket 1 is rotatably provided with two symmetrical guide rollers 11, which are used to clamp the fabric and guide the fabric. The take-up roller 18 is fixedly connected to a limiting member 2, which contacts the adjacent core 181 to make the through hole on the core 181 face the rectangular hole on the adjacent take-up roller 18.

[0057] In the above scheme, multiple rectangular through holes on the take-up roller 18 are circumferentially equidistantly distributed, and multiple through holes on the core 181 are arrayed on the sidewall. In the initial state, with attached... Figure 1 For example, the left take-up roller 18 is lower than the right take-up roller 18, and the upper surface of the right take-up roller 18 is slightly higher than the upper surface of the rotating roller 14, so that the right take-up roller 18 can contact the conveyed fabric. The conduit 19 is connected to the existing air pump, and the two guide rollers 11 clamp and guide the fabric to prevent the fabric from deviating during the conveying process.

[0058] Reference Figures 4-7 As shown, the locking mechanism includes: a sliding rod 3, which is slidably disposed in the cavity of an adjacent take-up roller 18 and a spring is installed between it and the adjacent take-up roller 18; a first sliding plate 31, which is fixedly connected to the sliding rod 3 and is located in the cavity of the take-up roller 18 for sealed sliding; an annular groove 311 is provided in the take-up roller 18, the maximum diameter of the annular groove 311 is larger than the diameter of the first sliding plate 31; a plurality of sliding shells 32 are slidably disposed on the take-up roller 18, the sliding shells 32 are used to squeeze adjacent cores 181; a first wedge block 33 is slidably disposed in the sliding shell 32, a spring is installed between the first wedge block 33 and the sliding shell 32; a plurality of second wedge blocks 34 are fixedly connected to the sliding rod 3, the second wedge blocks 34 are used to squeeze the adjacent first wedge block 33 to move.

[0059] In the above scheme, with attachment Figure 5 For example, the diameter of the annular groove 311 gradually increases from top to bottom. A magnet is provided on the first wedge block 33. The magnet on the wedge block 33 is attracted to the sliding rod 3 to prevent the wedge block 33 and the sliding shell 32 from detaching from the take-up roller 18. A rubber pad is provided on the side of the sliding shell 32 away from the sliding rod 3 to increase the friction between it and the core 181. The second wedge block 34 squeezes the adjacent first wedge block 33, so that the first wedge block 33 is away from the sliding rod 3.

[0060] Reference Figure 4 and Figure 8 As shown, the limiting mechanism includes: a spline rod 4, which is slidably mounted on an adjacent first sliding frame 16 and is fitted with a tension spring between itself and the adjacent first sliding frame 16; a third sliding frame 41, which is slidably mounted on the spline rod 4 and is fitted with a tension spring between itself and the spline rod 4, and the third sliding frame 41 is provided with a V-shaped surface; and a fixing strip 42, which is fixedly connected to the rotating shell 15, and the fixing strip 42 is provided with a wavy surface, and the wavy surface of the fixing strip 42 contacts the V-shaped surface of the third sliding frame 41.

[0061] In the above scheme, in the initial state, when the V-shaped surface of the third sliding frame 41 is in contact with the wavy surface of the adjacent fixing strip 42, the tension springs connected to the third sliding frame 41 and the first sliding frame 16 are always in a stretched state, so that the core 181 is tightly attached to the rotating roller 14. The end of the fixing strip 42 away from the center line of the rotating roller 14 is provided with a vertical surface. The vertical surface of the fixing strip 42 is used to restrict the movement of the third sliding frame 41, that is, to restrict the diameter of the rolled fabric on the core 181. When collecting different types of fabric, the operator adjusts the length of the fixing strip 42 and the size of the rotating roller 14 and other components according to the required thickness of the rolled fabric.

[0062] Specific working principle: During the fabric winding process, the operator first pulls the fabric through the two guide rollers 11, and then makes the fabric go around the upper side of the rotating roller 14, so that the end of the fabric is located between the core 181 on the left winding roller 18 and the rotating roller 14. Then, the device is started through the control module, which controls the existing air pump and drive unit 191 to work.

[0063] The air pump operates by drawing gas from the middle chambers of the two take-up rollers 18 through the conduit 19, the second air guide hole of the rotating roller 14, and the first air guide holes of the two first sliding frames 16. Subsequently, the gas in the upper chamber of the take-up roller 18 decreases, and the first sliding plate 31 inside the take-up roller 18 drives the sliding rod 3 to move closer to the adjacent annular groove 311. The sliding rod 3 moves and compresses the connected spring. At the same time, the sliding rod 3 moves and drives the adjacent second wedge block 34 to move and squeeze the adjacent first wedge block 33. The first wedge block 33 is squeezed and moves, causing the adjacent sliding shell 32 to fit against the adjacent core 181 through the connected spring, so that the core 181 is fixed relative to the adjacent take-up roller 18, ensuring that the take-up roller 18 drives the adjacent core 181 to rotate smoothly and avoid slippage between them. At the same time, when installing the core 181, the limiting effect of the limiting member 2 is used, and the through hole on the core 181 is directly opposite the rectangular hole on the adjacent take-up roller 18.

[0064] After the first sliding plate 31 moves into the adjacent annular groove 311, the outside gas enters the second air guide hole of the adjacent first sliding frame 16 through the through hole on the core 181, the rectangular hole on the take-up roller 18 and the chamber. At this time, the fabric will be adsorbed on the gas flow at the through hole on the core 181.

[0065] The drive unit 191 operates by driving the two take-up rollers 18 to rotate via the rotating sleeve 13 and two sets of transmission units 192. Since the core 181 is fixed relative to the adjacent take-up roller 18 at this time, the take-up roller 18 will drive the core 181 to rotate together. At this time, the core 181 on the left (as shown in the attached image)... Figure 1 (For example) The rotation winds up the fabric adsorbed on its outer surface, during which the right-side core 181 (with attached) Figure 1(For example) At the same time, it generates an adsorption force to adsorb the fabric passing over its upper side, flattening the fabric and preventing wrinkles from forming when the fabric is rolled up.

[0066] As the fabric is wound up, the diameter of the fabric roll on the left core 181 gradually increases. The left winding roller 18 and the left core 181 drive the adjacent first sliding frame 16 to move to the left. The leftward movement of the first sliding frame 16 stretches the connected tension spring. When the tension of the tension spring on the first sliding frame 16 is greater than the limiting force between the third sliding frame 41 and the adjacent fixing bar 42, the first sliding frame 16 causes the adjacent spline rod 4 to move the adjacent third sliding frame 41 through the connected tension spring. This causes the V-shaped surface on the third sliding frame 41 to be located in another "trough" of the wavy surface on the adjacent fixing bar 42, so that the clamping force between the core 181 and the rotating roller 14 on the wound fabric is kept within a certain range, thereby ensuring that the tension of the fabric roll remains relatively uniform after winding. The above operation is then repeated to continue winding the fabric.

[0067] After the fabric is wound to the specified thickness, the operator shuts down the device via the control module. Then, the operator releases the gripper on the left second sliding frame 17 from the left take-up roller 18. Afterward, the operator opens the gripper on the second sliding frame 17 by pulling out the limit pin, so that the gripper on the second sliding frame 17 releases the restriction on the core 181 and the fabric roll. Subsequently, the operator cuts the fabric and removes the fabric roll and core 181 from the left take-up roller 18 via a conveyor. Then, a new core 181 is installed on the left take-up roller 18, and the left second sliding frame 17 resumes its grip on the left take-up roller 18 and presses the take-up roller 18 to the right to reset. The above operation is then repeated to continue winding the fabric.

[0068] Before this device operates, the transmission ratio of the two transmission units 192 is set to regulate the rotational speed of the two take-up rollers 18 during the operation of the drive unit 191. When the rotational speed of the right take-up roller 18 is adjusted to be slower than that of the left take-up roller 18 (as shown in the attached diagram),... Figure 1 For example, the speed difference between the two take-up rollers 18 is used to apply a certain tension to the fabric, further ensuring that the fabric is smoothly wound onto the take-up roller 18 on the left.

[0069] Example 2: Based on Example 1, referring to... Figure 2 , Figure 8 and Figure 10 As shown, it also includes: a drive motor 5, fixedly connected to the bracket 1; a first rotating frame 12 rotatably connected to the bracket 1; the output shaft of the drive motor 5 fixedly connected to the first rotating frame 12; a rotating shell 15 rotatably connected to the rotating roller 14; a first sliding frame 16 provided with a winding mechanism; a bracket 1 provided with a driving mechanism; the winding mechanism and the driving mechanism cooperate to wind the fabric onto the adjacent core 181; and a bracket 1 provided with a cutting mechanism for cutting the fabric.

[0070] In the above scheme, with attachment Figure 8 For example, when the rotating shell 15 is in a horizontal state, the first air guide hole of the first sliding frame 16 on the left side is not connected to the second air guide hole of the rotating roller 14. In this state, it is convenient for the operator to remove the upper core 181 of the upper winding roller 18 on the left side, so that the fabric roll can be removed after winding is completed.

[0071] Reference Figure 3 and Figure 9 As shown, the winding mechanism includes: a second rotating frame 6, which is rotatably mounted on an adjacent first sliding frame 16; a second sliding plate 61, which is slidably mounted on the second rotating frame 6 and a spring is installed between it and the second rotating frame 6; and a first rotating rod 62 symmetrically distributed on the second sliding plate 61.

[0072] In the above scheme, there are two first rotating rods 62 that are centrally symmetrically distributed. A rubber ring is provided on the outer side of the second rotating frame 6. The maximum diameter of the second sliding plate 61 is greater than the maximum diameter of the second rotating frame 6, which facilitates the subsequent pressing and movement of the second sliding plate 61. In the initial state, under the action of the spring on the second sliding plate 61, the second sliding plate 61 is in contact with the adjacent second rotating frame 6. A frustum is provided at the end of the first rotating rod 62 away from the adjacent second sliding plate 61.

[0073] Reference Figures 10-12 As shown, the driving mechanism includes: a fixed frame 63, fixedly connected to the bracket 1; a sliding block 64, slidably disposed on the fixed frame 63, and a tension spring installed between the sliding block 64 and the fixed frame 63; a second rotating rod 65, rotatably disposed on the sliding block 64; a rotating wheel 66, fixedly connected to the second rotating rod 65, the rotating wheel 66 being used to contact and press the corresponding second rotating frame 6; a turntable 67, rotatably disposed on the second rotating rod 65, the turntable 67 being fixedly connected to an internal gear ring; a fixed rod 68, fixedly connected to the sliding block 64, the fixed rod 68 being rotatably disposed with a gear, the second rotating rod 65 being fixedly connected to a gear, the gear of the second rotating rod 65 and the internal gear ring of the turntable 67 both meshing with the gear of the fixed rod 68; and a limiting frame 7, fixedly connected to the sliding block 64, the limiting frame 7 being used to press the corresponding second sliding plate 61.

[0074] In the above scheme, rubber rings are provided on the outer side of the turntable 66 and the outer side of the turntable 67. The two gears and the internal gear ring on the turntable 67, the fixed rod 68 and the second rotating rod 65 form a planetary gear set, so that the rotation direction of the turntable 67 is opposite to the rotation direction of the second rotating rod 65. The limiting frame 7 is provided with two inclined surfaces. The two inclined surfaces of the limiting frame 7 gradually approach each other from the turntable 67 to the turntable 66. The inclined surfaces of the limiting frame 7 are used to guide the second sliding plate 61 passing by it to move.

[0075] Reference Figure 1 , Figure 10 and Figure 11 As shown, the cutting mechanism includes: a first fixed shell 8, fixedly connected to the bracket 1; a third sliding plate 81, slidably disposed inside the first fixed shell 8, and a spring installed between the third sliding plate 8 and the first fixed shell 8, the third sliding plate 81 being provided with a cutting blade; a rack 82, fixedly connected to the third sliding plate 81, the rack 82 being provided with two telescopic parts that move in the horizontal direction and in the vertical direction; a second fixed shell 83, fixedly connected to the limiting frame 7, and a second rotating rod 65 penetrating the second fixed shell 83 and rotatably connected to it; and a spur gear 84, fixedly connected to the second rotating rod 65, located inside the second fixed shell 83 and meshing with the rack 82.

[0076] In the above scheme, the extension line of the moving path of the third sliding plate 81 passes through the center line of the rotating roller 14, and both telescopic parts of the rack 82 are provided with tension springs. The telescopic part of the rack 82 in the vertical direction is used to adapt to the up and down movement of the sliding block 64. The elastic coefficient of the tension spring of the telescopic part of the rack 82 in the horizontal direction is greater than the elastic coefficient of the spring connected to the third sliding plate 81. The telescopic part of the rack 82 in the horizontal direction is used to ensure that the cutting blade on it stops moving after cutting the fabric.

[0077] Specific working principle (if no attached diagram is shown during operation, refer to the attached diagram for directional terms). Figure 1 (Direction in the middle): During the fabric winding process, when the fabric on the left core 181 is nearly finished winding, the control module starts the drive motor 5. The drive motor 5 drives the first rotating frame 12 and the two second sliding frames 17 to rotate, making the first rotating frame 12 vertical and stopping it in the vertical position for a period of time. During this process, the rotation of the two second sliding frames 17 drives the two first sliding frames 16 and the rotating shell 15 to rotate through the two winding rollers 18. During the rotation of the first sliding frame 16, it drives the adjacent second rotating frame 6 and the second sliding plate 61 to rotate. When the second sliding plate 61 rotates to the vicinity of the limiting frame 7, the inclined surface of the limiting frame 7 presses the second sliding plate 61 to move. The second sliding plate 61 drives the two adjacent first rotating rods 62 to move, one of which is located on the upper side of the fabric and the other is located on the lower side of the fabric (as shown in the attached figure). Figure 12 (As shown).

[0078] After the second sliding plate 61 has moved, the second rotating frame 6 rotates to the contact wheel 66, and the take-up roller 18 is in contact with the turntable 67. The rotation of the take-up roller 18 drives the adjacent second rotating frame 6 and the second sliding plate 61 to rotate through the turntable 67, the planetary gear set, the second rotating rod 65 and the wheel 66. At this time, the rotation direction of the second sliding plate 61 is the same as the rotation direction of the take-up roller 18. The second sliding plate 61 drives the two first rotating rods 62 to rotate and wrap the fabric around the upper core 181. The fabric is automatically wrapped around the other core 181. At this time, the fabric is wrapped around the core 181 in a double layer. The double layer bending of the fabric avoids wrinkles in the fabric in the early stage of wrapping. At the same time, with the adsorption effect of the core 181 on the fabric, the fabric is neatly wrapped around the upper core 181 and the winding efficiency of the fabric is improved. The moving range of the sliding block 64 is used to adapt to the thickness change of the fabric being wound by the core 181.

[0079] During the rotation of the second rotating rod 65, the second rotating rod 65 drives the rack 82 to move through the spur gear 84. The rack 82 drives the third sliding plate 81 to move through the horizontally varying tension spring on it. The movement of the third sliding plate 81 compresses the connected spring until the cutting edge on the third sliding plate 81 cuts the fabric. Then, the control module starts the drive motor 5, which controls the first rotating frame 12 to rotate to a horizontal state. At this time, the core 181 on the left is in the state of winding the fabric, while the core 181 on the right has completed the winding of the fabric, forming a fabric roll. During the rotation of the first rotating frame 12 to a horizontal state, the second sliding plate 61 gradually disengages from the contact with the limiting frame 7. The second sliding plate 61 is subjected to the elastic force of the connected spring and moves in the opposite direction to reset. At the same time, it is subjected to the elastic force of the connected spring of the third sliding plate 81 and moves in the opposite direction to reset.

[0080] When the first rotating frame 12 is in a horizontal state, with the attached Figure 8 For example, the first air guide hole of the first sliding frame 16 on the left side is not connected to the second air guide hole of the rotating roller 14. In this state, it is convenient for the operator to repeat the above operation to remove the core 181 and the fabric roll on the upper winding roller 18 on the left side, and install a new core 181. The drive motor 5 is started through the control module, and the drive motor 5 controls the first rotating frame 12 to rotate to the initial state (as shown in the attached figure). Figure 1 (as shown in the diagram), and then repeat the above operation to make the two cores 181 perform automatic alternating fabric winding operation.
