Description

Technical Field

[0001] Embodiments of the present invention relate to the technical field of fabric slitting, and specifically, to a shared drawing shaft type fabric slitting device. Background Art

[0002] During the production and processing of fabrics, it is necessary to perform slitting operations on a whole piece of fabric. The existing methods for slitting fabrics usually fix the reel with the whole piece of fabric wound thereon to the unwinding rack, then unwind the fabric into the fabric slitting device. After using the fabric slitting device to perform slitting operations on the fabric, the at least two slit fabrics are then wound by the winding rack to complete the winding operation of the fabric.

[0003] In the existing technology, for the winding rack that winds the slit fabrics, each fabric is wound separately, and there will be a phenomenon that at least two winding racks are arranged side by side. In this way of winding the fabric, after the fabric is slit, it will be wound in a way that slightly moves to both sides. On the one hand, the overall width of multiple winding racks will exceed the installation width of the unwinding rack, and it is also very easy to affect the position of the fabric in the fabric slitting device when winding the fabric. In addition, after performing slitting operations on the fabric, it is also necessary to wind the narrow strips of the slit fabric. If a device for winding the narrow strips of the fabric is set up separately, it will not only increase the installation area of the slitting device, but also increase the complexity of operating the slitting device. However, if the narrow strips of the fabric are not effectively wound, there will also be a problem of accumulation of the narrow strips of the fabric. Summary of the Invention

[0024] As Figures 1 to 7 shown, the present invention discloses a shared shaft-pulling type cloth slitting device, including a slitting device body 1. The slitting machine body is a prior art device well-known to those skilled in the art. During the process of guiding and conveying the unwound cloth, the slitting device is used to perform slitting operations on the cloth. It further includes a unwind bracket 2. The unwind bracket 2 is arranged on one side of the slitting device body 1. Two relatively movable insertion shafts 3 are arranged at the top of the unwind bracket 2. The cloth reel is fixed between the two insertion shafts 3. Two bottom support seats 4 cooperating with the insertion shafts 3 are also arranged at the top of the unwind bracket 2. Two inclined slide rails 7 are arranged in the middle of the unwind bracket 2. A sliding member 8 is slidably connected to the inclined slide rails 7. The bottom support seat 4 is fixedly connected to the top of the sliding member 8. By driving the bottom support seat 4 to move horizontally, the sliding member 8 moves on the inclined slide rails 7. By moving the bottom support seat 4 to different horizontal positions, the bottom support seat 4 and the sliding member 8 are located at different positions on the inclined slide rails 7, so as to adjust the height and horizontal position of the bottom support seat 4 to perform bottom support for cloth reels with different outer diameters. A moving operation structure is provided between the insertion shaft 3 and the bottom support base 4 for adjusting the positions of the insertion shaft 3 and the bottom support base 4. The moving operation structure includes an installation chamber 9 and a sliding seat 11. An installation chamber 9 is provided in the middle of the unwinding bracket 2. Two transmission screws 10 are rotatably connected in the installation chamber 9. The two transmission screws 10 are fixedly connected. Threaded sections with the same thread are provided on both sides of the transmission screw 10. Two sliding seats 11 are slidably connected to both sides of the installation chamber 9. A transmission nut set 12 is horizontally slidably connected in the sliding seat 11. The transmission nut set 12 is in transmission cooperation with the corresponding threaded section. Magnetic positioning components are provided on both sides of the transmission nut set 12 and the sliding seat 11. A first drive motor 24 is provided on one side of the unwinding bracket 2. The shaft-type output end of the first drive motor 24 is fixedly connected to the transmission screw 10 on one side. When it is necessary to adjust the positions of the insertion shaft 3 and the bottom support base 4, the first drive motor 24 is started to drive the two transmission screws 10 to rotate synchronously. The transmission nut set 12 is used to drive the sliding seat 11 to move horizontally in the installation chamber 9. The sliding seat 11 will drive the corresponding insertion shaft 3 or bottom support base 4 to move horizontally, so that the insertion shaft 3 and the bottom support base 4 can fixedly support a fabric reel of an appropriate length. A rotating bracket is provided at the top of the sliding seat 11 corresponding to the insertion shaft 3. The insertion shaft 3 is rotatably connected to the rotating bracket. When the fabric reel unwinds the fabric to be slit, the fabric reel and the two insertion shafts 3 rotate together between the two rotating brackets to unwind the fabric reel; The magnetic positioning component includes an electromagnet 13 and a magnetic sheet 14. Electromagnets 13 are provided at the top of both sides of the sliding seat 11. Magnetic sheets 14 are embedded on the upper and lower sides of the transmission nut set 12.

Because during the rotation of the two transmission screws 10, the transmission nut set 12 will move horizontally in the sliding seat 11. In order to achieve the working purpose of moving the insertion shaft 3 and the bottom support base 4 in sequence, when it is necessary to move two corresponding sliding seats 11, the electromagnets 13 on one side in these two sliding seats 11 are magnetically connected to the magnetic sheets 14, and then the sliding seat 11 is connected to the transmission nut set 12. During the horizontal movement of the transmission nut set 12, the sliding seat 11 is driven to move horizontally. For the remaining two sliding seats 11, the magnetic connection between the electromagnet 13 and the magnetic sheet 14 is released, so that the transmission nut set 12 moves horizontally in the sliding seat 11 to achieve the separate movement of the insertion shaft 3 and the bottom support base 4; When fixing the fabric reel using the above method, first, adjust the positions of the two bottom support seats 4 according to the fabric winding amount and width of the fabric reel, so that the connection between the sliding seat 11 corresponding to the insertion shaft 3 and the transmission nut group 12 is released. Then, adjust the bottom support seat 4 to the designated position, and then release the connection between the sliding seat 11 corresponding to the bottom support seat 4 and the transmission nut group 12. Then, connect the sliding seat 11 corresponding to the insertion shaft 3 and the transmission nut group 12, and then adjust the lateral position of the insertion shaft 3 through the transmission screw 10. After the shaft sleeve is installed, the insertion shaft 3 extends into the fabric reel to clamp and fix the fabric reel.

[0025] A telescopic connection structure is provided between the sliding seat 11 corresponding to the bottom support seat 4 and the sliding member 8 to adapt to the distance change between the bottom support seat 4 and the sliding seat 11.

A lengthening rod 26 is slidably arranged in the receiving groove 25, and the lengthening rod 26 is fixedly connected to the sliding member 8. As the height changes during the movement of the bottom support seat 4, the lengthening rod 26 moves in the receiving groove 25 to adapt to the distance difference between the sliding seat 11 and the sliding member 8. A plurality of rotating wheels 27 are rotatably connected to the bottom of the sliding seat 11, and the rotating wheels 27 are in contact with the inner bottom wall of the installation chamber 9, making the lateral movement of the sliding seat 11 in the installation chamber 9 smoother.

When it is necessary to adjust the position of the shaft driving device 15, the second driving motor 28 is started to drive the bidirectional screw 18 to rotate. The bidirectional screw 18 drives the moving nut groups 19 to move horizontally in the installation groove frame 6, and the moving nut groups 19 will drive the shaft driving device 15 to move horizontally on the sliding frame 21; The side groove frame 20 is fixedly connected to one side of the installation groove frame 6. Screw rod transmission structures are arranged on both sides inside the side groove frame 20.

The winding shaft contacts the placing slope 22 to prevent the winding shaft and the fabric from moving randomly.

[0029] Wherein, cloth strip winding structures are provided on the opposite sides of the two fabric winding structures.

When the rotating shaft type output end drives the winding cylinder 23 to wind the narrow cloth strips, under the action of the driving gears 32 and the driving toothed belt, the reciprocating lead screw 31 will drive the guiding member 33 to perform a horizontal reciprocating movement, so that the narrow cloth strips are evenly arranged on the winding cylinder 23, and the winding cylinder 23 winds the narrow cloth strips evenly. And through the sliding connection relationship between the extension strip 34 and the slot 35, the guiding member 33 moves horizontally.

[0030] The working principle of the shared shaft-pulling type fabric slitting device is as follows: Fix the fabric reel to the unwinding bracket 2, so that the two inserting shafts 3 clamp the fabric reel. Then adjust the position of the shaft driving device 15 so that the positions of the two shaft driving devices 15 correspond to the positions of the two inserting shafts 3. Then, according to the different widths of the two fabrics after slitting, adjust the positions of the two moving seats 17, and fix the winding shaft close to the width after fabric slitting between the two clamping shafts 16, so that the installation width between the unwinding bracket 2 and the winding bracket 5 corresponds, and the fabric can be wound in a straight line after slitting. In addition, the cloth strip winding structure can also wind the narrow cloth strips generated after slitting.
