Description

Technical Field

[0001] The invention relates to the technical field of cloth rolling, in particular to a knitted wool sweater fabric rolling device. Background Art

[0002] Knitted wool sweater fabric is a wool fiber fabric made by knitting process, which has high softness and elasticity. During the production process, the fabric is output in continuous long strips. In order to facilitate the transportation or storage of the fabric, the fabric needs to be neatly wound on the textile reel with the help of a winding device, which can prevent the fabric from folding and wrinkling, save space, maintain the flatness of the fabric, and facilitate handling.

[0003] The existing winding device mainly relies on a winding roller to complete the winding operation of the knitted wool sweater fabric. Specifically, the winding roller is driven to rotate by a driving mechanism, and the textile reel is fixed outside the winding roller, and one end of the knitted wool sweater fabric is fixed outside the textile reel. When the winding roller rotates, the textile reel can be driven to rotate, and then the long strip of knitted wool sweater fabric will be continuously wound outside the textile reel.

[0004] However, when the knitted wool sweater fabric that has been rolled up needs to be unloaded, the textile reel outside the winding roller must first be loosened, and then the fabric roll must be pushed horizontally along the axis of the winding roller until the textile reel in the center of the fabric roll can be slid out of the winding roller. At this time, the fabric roll can be picked up by the fork of a forklift or a transport cart in the workshop. At this time, due to the long overall length of the winding roller, the translation and pushing operation of the fabric roll is not only time-consuming and laborious, but also inconvenient to pick up the fabric roll that falls after translation and pushing, which brings inconvenience. At the same time, the tail of the fabric roll is not in a fixed state at this time, which easily causes the fabric roll to loosen.

[0042] Specifically, starting the second motor 10 can drive the support frame 4 to rotate, and the support frame 4 can drive the turntable 1 to rotate.

[0043] Working principle: First, fix the textile reel 35 outside the two support tubes 12, specifically: start the two-way slide 7, so that the two workbenches of the two-way slide 7 move away from each other, and the two support plates 8 move away from each other accordingly, and the two support plates 8 can drive the respectively connected turntables 1 to move together, and each turntable 1 can drive the respectively connected support tube 12 to move together, and each support tube 12 can drive the respectively connected connecting column 13 to move together, until the distance between the two connecting columns 13 is away from each other to a length that can accommodate the textile reel 35. Then, the textile drum 35 is placed between the two connecting columns 13, and the two workbenches are driven to move closer to each other by the two-way slide 7, then the two turntables 1, the two support cylinders 12, and the two connecting columns 13 will move closer to each other, and the two connecting columns 13 will penetrate into the textile drum 35, and the two support cylinders 12 will not only penetrate into the textile drum 35, but also the outer walls of the two support cylinders 12 will fit with the inner wall of the textile drum 35, until the limit rings 11 on the outer walls of the two support cylinders 12 move to clamp the two ends of the textile drum 35 respectively, thereby fixing the textile drum 35, and then one end of the fabric body 3 can be fixed to the outside of the textile drum 35 by other means such as gluing, and finally the two turntables 1 can be driven to rotate by the driving mechanism, then the textile drum 35 and the two support cylinders 12 will rotate synchronously, so that the fabric body 3 is continuously wound outside the textile drum 35, as shown in FIG. Figure 1 It should be noted that, after the fabric body 3 is rolled up, the tail of the fabric body 3 is rotated to be at the top, so that the tail of the fabric body 3 will not hang down.

[0044] When the rolled fabric body 3 needs to be unloaded, first start the motor 5 connected to a turntable 1, the motor 5 can drive the stud 21 to rotate, the stud 21 can drive the connecting ring 23 to move in the direction of the turntable 1, the connecting ring 23 can drive the four connecting plates 20 to rotate synchronously, the four connecting plates 20 can drive the blocks 22 connected to them to move away from the center of the turntable 1, the four blocks 22 can drive the pillars 17 connected to them to slide in the corresponding slide grooves 15 in the direction away from the center of the turntable 1, each pillar 17 will drive the arc block 16 that fits them to move together, and the pillars 17 and the arc block 16 are magnetic Made of iron material, the arc block 16 can be firmly adsorbed on the outside of the pillar 17, and each arc block 16 will drive the L-shaped rod 18 connected to it to slide in the corresponding concave groove 14, and each L-shaped rod 18 will drive the rectangular rod 29 connected to it to slide in the corresponding rectangular shell 28. The movement of the four pillars 17 can expand the rubber ring 2 (the rubber ring 2 is an elastomer with deformation ability and also has deformation ability) until the diameter of the rubber ring 2 is larger than the diameter of the rolled fabric body 3. Similarly, starting the motor 5 connected to another turntable 1 can drive the diameter of another rubber ring 2 to expand.

[0045] The limiting ring 11 is fixedly connected to the outside of the support tube 12 by screws, that is, the inner wall of the limiting ring 11 is threaded with screws, and the outer wall of the support tube 12 is provided with screw holes corresponding to the screws. The screws and the screw holes are both well-known in the prior art and will not be described in detail. For details, please refer to Fig.10Then, the screws on the two limit rings 11 are rotated in sequence until the two screws leave the corresponding screw holes, and then the two workbenches are driven to move closer to each other through the two-way slide 7. During the process, the staff can hold the fabric body 3 with their hands, and then the two turntables 1, the two support tubes 12, and the two connecting columns 13 will continue to move closer to each other (it should be noted that the outer wall of the support tube 12 will slide against the inner wall of the limit ring 11, and the limit ring 11 is always in contact with the end of the textile reel 35), and the support 17 connected to the two turntables 1 will also move accordingly, then The two rubber rings 2 will be driven to move closer to each other, the four pillars 17 connected to each turntable 1 and each rubber ring 2 will move to the outside of the rolled fabric body 3, the two connecting columns 13 will move closer to each other until they are in contact with each other, and as they continue to move, the two support tubes 12 will eventually fit together. In this process, each connecting column 13 will be squeezed and move into the corresponding support tube 12, each connecting column 13 will drive the fixing ring 24 to squeeze the spring 25 connected to the corresponding U-shaped block 26, and each connecting column 13 will drive the fixing ring 24 to squeeze the spring 25 connected to the corresponding U-shaped block 26, and each connecting column 13 will drive the fixing ring 24 to squeeze the spring 25 connected to the corresponding U-shaped block 26. The connected toothed plates 27 drive the corresponding gears 33 to rotate, and each gear 33 drives another toothed plate 27 meshing with the top thereof to move toward the center of the textile reel 35, and the two toothed plates 27 drive the connected connecting blocks 34 to slide in the corresponding guide grooves 31, and each connecting block 34 drives the connected splicing ring 30 to slide outside the corresponding support tube 12 toward the center of the textile reel 35, and each splicing ring 30 drives the connected four rectangular shells 28 to move together, and each rectangular shell 28 can drive the rectangular rods inside each 29 moves together, each rectangular rod 29 can drive the L-shaped rod 18 connected to it to move together, and each L-shaped rod 18 will drive the arc block 16 connected to it to move together, that is, the arc block 16 outside the four pillars 17 connected to the turntable 1 at each location will push the corresponding rubber ring 2 out of the four pillars 17, and at this time the arc block 16 will move to be flush with the end of the pillar 17, then the two rubber rings 2 will quickly restore their shapes, and the two rubber rings 2 will be respectively tightened on both sides of the rolled fabric body 3, thereby fixing the tail of the fabric body 3.

[0046] Finally, the two workbenches of the two-way slide 7 are driven to move away from each other. During the process, the staff can hold the fabric body 3 with their hands, and the two turntables 1, the two support cylinders 12, and the two connecting columns 13 will move away from each other, then the support 17 will leave the outside of the fabric body 3, and then continue to control the two workbenches of the two-way slide 7 to move away from each other until the two support cylinders 12 are completely separated from the interior of the textile reel 35. At this time, the rolled fabric body 3 can fall vertically downward to complete the unloading.

[0047] It should be noted that the rubber ring 2 is an ordinary elastic part, and the staff can prepare multiple ones. After the fabric body 3 is rolled up and unloaded once, the new rubber ring 2 can be put on the corresponding four pillars 17, and the rubber ring 2 and the outer walls of the four pillars 17 will also form a tight fit, that is, the rubber ring 2 needs to be slightly pulled and expanded to be placed outside the four pillars 17 that are not synchronously away from the center of the turntable 1.

[0048] It should also be noted that when the fabric body 3 is rolled up next time, the limiting ring 11 can be slid outside the support tube 12 to the corresponding screw hole, and the screw can be rotated to tighten it in the screw hole, so as to achieve the fixation between the limiting ring 11 and the support tube 12, and the limiting ring 11 can continue to play a clamping role on the textile reel 35. The screws and screw holes are all well-known existing technologies and will not be described in detail. For details, please refer to Fig.10 Come and see.

[0049] It should also be noted that the textile reel 35 can be quickly installed outside the two supporting tubes 12. When the knitted wool sweater fabric is rolled up on the textile reel 35, the two rubber rings 2 can be driven to expand and finally be tightened on both sides of the fabric roll to simply fix the tail of the fabric roll. When the rolled up knitted wool sweater fabric needs to be unloaded, the textile reel 35 and the fabric roll can fall vertically without the need to push the fabric roll horizontally and then drop it. Not only is the operation convenient, but the fabric roll can also be easily picked up by the fork of a forklift or a transport cart in the workshop.
