Description

Technical Field

[0001] This utility model relates to the field of fabric anti-deviation in fabric spreading machines, and in particular to a fabric positioning device for fabric spreading machines that prevents deviation. Background Technology

[0002] In the production process of industries such as textiles, clothing and home textiles, the fabric spreading machine is the core equipment that connects the fabric storage with the subsequent cutting and sewing processes. Its core function is to continuously and stably convey rolls of fabric to the processing station according to preset length and flatness requirements.

[0003] The stability of fabric conveying on the fabric spreading machine is directly related to the accuracy of subsequent cutting dimensions, sewing and splicing effects, and even the quality pass rate of the final product. Therefore, "preventing fabric conveying deviation" has become a key technical requirement to be addressed in the design and application of fabric spreading machines, and it is also a basic prerequisite for ensuring the efficient operation of the production line.

[0004] Most entry-level fabric spreading machines use a fixed-width edge guard structure for positioning. This type of structure cannot be flexibly adjusted according to the width of different batches of fabric. When changing fabric specifications, it is necessary to disassemble and replace the corresponding edge guard component, which is not only cumbersome and time-consuming, but also prone to fabric wear due to hard friction between the edge guard and the edge of the fabric. Therefore, a fabric positioning device for anti-skew fabric spreading machines is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a fabric positioning device for an anti-skew fabric spreading machine, which aims to improve the problem of inconvenient adjustment in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a fabric positioning device for an anti-skew fabric pulling machine, comprising a base plate, a vertical plate fixedly connected to the upper side of the base plate, a rotating shaft rotatably connected to the inner rear wall of the vertical plate, a fixed column fixedly connected to the rear side of the vertical plate, a rotating block threadedly connected to the outer wall of the fixed column, a limit ring rotatably connected to the rear side of the rotating block, a fabric pulling roller fixedly connected to the outer wall of the rotating shaft, a guide assembly provided on the rear side of the vertical plate for guiding the limit ring, and a deviation correction assembly provided on the upper side of the vertical plate for correcting the deviation of the fabric.

[0007] As a further description of the above technical solution: The correction assembly includes a connecting block, which is fixedly connected to the upper side of the upright plate. A fixing block is fixedly connected to the upper side of the connecting block. A correction roller is slidably connected to the inner rear wall of the fixing block.

[0008] As a further description of the above technical solution: The guide assembly includes a fixing rod, which is fixedly connected to the rear side of the upright plate, and a connecting plate is slidably connected to the outer wall of the fixing rod.

[0009] As a further description of the above technical solution: One end of the spring is fixedly connected to the rear side of the clamping block, and the other end of the spring is fixedly connected to the inner wall of the front side of the correction roller.

[0010] As a further description of the above technical solution: The rear side of the locking block is slidably connected to the inner wall of the front side of the correction roller, and the front side of the locking block is engaged with the inner wall of the fixing block.

[0011] As a further description of the above technical solution: The fixing block is arc-shaped, and a through hole is provided on the inner wall of the fixing block.

[0012] As a further description of the above technical solution: The lower side of the limiting ring is fixedly connected to the upper side of the connecting plate, and the limiting ring slides on the outer wall of the fabric pulling roller.

[0013] As a further description of the above technical solution: The fixing column is hollow, and its inner diameter is slightly larger than the outer diameter of the rotating shaft.

[0014] This utility model has the following beneficial effects: 1.

[0018] 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.

[0019] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a fabric positioning device for an anti-skew fabric spreading machine, comprising a base plate 1, which provides a stable support foundation for the entire device. A vertical plate 8 is fixedly connected to the upper side of the base plate 1, serving to install and support other components. A rotating shaft 11 is rotatably connected to the inner rear wall of the vertical plate 8, providing support for the rotation of the fabric spreading roller 4. The rotating shaft 11 is driven by a driver. A fixing column 10 is fixedly connected to the rear side of the vertical plate 8, serving as a connection and initial limiting mechanism. The fixing column 10 provides support for the rotation of the rotating block 13. The fixing column 10 is hollow, and its inner diameter is slightly larger than that of the rotating shaft 11. The outer diameter of the fixed column 10 is connected to a rotating block 13 by a thread. The rotating block 13 can adjust the position of the limiting ring 5 by rotation. The limiting ring 5 is rotatably connected to the rear side of the rotating block 13. The limiting ring 5 is used to limit the offset of the fabric pulling roller 4. The lower side of the limiting ring 5 is fixedly connected to the upper side of the connecting plate 12. The fixed rod 2 provides a guide track for the sliding of the connecting plate 12. The limiting ring 5 slides on the outer wall of the fabric pulling roller 4. The fabric pulling roller 4 is fixedly connected to the outer wall of the rotating shaft 11. The fabric pulling roller 4 is used to convey the fabric. A guide assembly is provided on the rear side of the upright plate 8. The guide assembly is used to guide the limiting ring 5. A correction assembly is provided on the upper side of the upright plate 8. The correction assembly is used to correct the offset of the fabric.

[0020] Reference Figure 1 , Figure 3 and Figure 4The correction assembly includes a connecting block 7, which connects the upright plate 8 and the fixing block 6. The connecting block 7 is fixedly connected to the upper side of the upright plate 8, and the fixing block 6 is fixedly connected to the upper side of the connecting block 7. The fixing block 6 provides a structure for the installation and adjustment of the correction roller 3. The fixing block 6 is arc-shaped, and a through hole is provided on the inner wall of the fixing block 6. The correction roller 3 is slidably connected to the rear inner wall of the fixing block 6. The correction roller 3 achieves the correction function by contacting the fabric. A locking block 9 is elastically connected to the front inner wall of the correction roller 3 by a spring 14. The spring 14 provides elastic force to the locking block 9, so that the locking block 9 can be stably locked onto the fixing block 6. The rear side of the locking block 9 is slidably connected to the front inner wall of the correction roller 3, and the front side of the locking block 9 is locked onto the inner wall of the fixing block 6. One end of the spring 14 is fixedly connected to the rear side of the locking block 9, and the other end of the spring 14 is fixedly connected to the front inner wall of the correction roller 3.

[0021] Reference Figure 1 and Figure 2 The guide assembly includes a fixed rod 2, which provides a guide track for the sliding of the connecting plate 12. The fixed rod 2 is fixedly connected to the rear side of the upright plate 8, and the connecting plate 12 is slidably connected to the outer wall of the fixed rod 2.

[0022] Working principle: The fabric is placed on the fabric-pulling roller 4, and the driver drives the rotating shaft 11 to rotate, which drives the fabric-pulling roller 4 to rotate synchronously, thereby realizing the transfer of the fabric.

[0023] To prevent the fabric from shifting laterally on the fabric-pulling roller 4, initial positioning can be achieved by adjusting the position of the limiting ring 5: Rotate the rotating block 13, which is threadedly connected to the fixed column 10. Since the rotating block 13 is rotatably connected to the limiting ring 5, and the lower side of the limiting ring 5 is slidably connected to the fixed rod 2 (guide assembly) through the connecting plate 12, the rotation of the rotating block 13 will drive the limiting ring 5 to move smoothly along the axial direction of the fabric-pulling roller 4 (the connecting plate 12 slides along the fixed rod 2 to ensure the stability of the movement), until the limiting ring 5 fits against both sides of the fabric, thereby limiting the lateral shift of the fabric when it is conveyed on the fabric-pulling roller 4.

[0024] When a slight deviation occurs during fabric conveying, the correction component comes into play: pressing the locking block 9 compresses the spring 14 and retracts it into the correction roller 3, disengaging it from the through hole in the inner wall of the fixing block 6; then the correction roller 3 slides along the rear inner wall of the arc-shaped fixing block 6, adjusting its position and angle according to the direction of fabric deviation; after adjustment, the locking block 9 is released, the spring 14 resets, and pushes the front of the locking block 9 back into the corresponding through hole in the fixing block 6, thus fixing the correction roller 3; at this time, the correction roller 3 contacts the deviated fabric, applying lateral guiding force to the fabric through its position and angle, guiding the fabric back to the correct conveying path, thus completing the correction.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
