Description

Technical Field

[0001] This application relates to the field of warp knitting machines, and more particularly to a fabric output device for a warp knitting machine. Background Technology

[0002] Warp-knitted flannel fabric is a new type of double-needle bed pile product, and the production equipment is usually a warp knitting machine.

[0003] Warp knitting machines are mainly composed of a knitting mechanism, a comb bar traverse mechanism, a warp feeding mechanism, a take-up and pull mechanism, and a transmission mechanism. Their working principle is to use one or more groups of parallel yarns to be fed into all the working needles of the machine in the warp direction to form a knitted fabric at the same time. The take-up and pull mechanism pulls the knitted fabric out at a predetermined speed and winds it into a roll.

[0004] When the fabric is rolled up, it has a certain degree of elasticity. When it is pulled during the rolling process, the edges are prone to curling, which will result in the fabric being uneven after rolling, making it difficult to process in subsequent processes. Utility Model Content

[0005] To address the problem of fabric curling after exiting the machine, resulting in uneven fabric after winding, this application provides a fabric exit device for a warp knitting machine.

[0006] The fabric output device of the warp knitting machine provided in this application adopts the following technical solution:

[0007] A fabric output device for a warp knitting machine includes a frame disposed on one side of the warp knitting machine. Along the fabric transport direction, an expanding roller, a spreading assembly, a guide roller, and a take-up roller are sequentially arranged on the frame. A take-up motor for driving the take-up roller is disposed on the frame. The spreading assembly includes a receiving wheel and a spreading wheel. Mounting frames are disposed opposite each other on both sides of the frame in the width direction. The spreading wheel and the receiving wheel are rotatably mounted on the mounting frames and are distributed vertically in parallel. A spreading space is formed between the spreading wheel and the receiving wheel for the fabric to pass through.

[0008] By adopting the above technical solution, after the warp knitting machine outputs the fabric, it is expanded by the spreading roller. The two sides of the fabric pass between the spreading roller and the receiving roller. The spreading roller on both sides spreads the edges of the fabric. The fabric is then transported to the winding roller by the guide roller and wound up. After the fabric is expanded and spread, it is wound up again. The fabric is less likely to curl at the edges when it is wound up.

[0009] Optionally, the mounting frame is provided with a connecting frame, the edge-spreading wheel is rotatably mounted on the connecting frame, the mounting frame is slidably connected to the frame, and the frame is provided with an adjusting member that drives the mounting frames on both sides to slide in opposite directions.

[0010] By adopting the above technical solution, the adjusting component moves the mounting frames on both sides, thereby driving the edge-spreading wheels and receiving wheels on the mounting frames to move, adjusting the position of the edge-spreading wheels on both sides, which is suitable for edge-spreading operations on fabrics of different widths.

[0011] Optionally, the adjusting component includes an adjusting motor and an adjusting lead screw. The adjusting lead screw is rotatably mounted on the frame and distributed along the width direction of the frame. The adjusting motor is mounted on the frame. The adjusting lead screw is connected to the output shaft of the adjusting motor. The adjusting lead screw is provided with two opposite threads. The mounting brackets on both sides are threadedly connected to the adjusting lead screw at the two threaded sections respectively.

[0012] By adopting the above technical solution, the adjustment motor drives the adjustment screw to rotate, and the adjustment screw drives the mounting brackets on both sides to slide in opposite directions, thereby adjusting the position of the mounting brackets on both sides, making the adjustment operation convenient.

[0013] Optionally, the frame is provided with sliding rods that are distributed parallel to the adjusting screw, and the mounting bracket is slidably connected to the sliding rods.

[0014] By adopting the above technical solution, when the mounting frame is driven to move, the mounting frame slides along the sliding rod, and the sliding rod guides and limits the movement of the mounting frame.

[0015] Optionally, the edge-unfolding wheel is provided with anti-slip threads, and the anti-slip threads on both sides of the edge-unfolding wheel have opposite spiral directions.

[0016] By adopting the above technical solution, when the fabric passes between the spreading wheel and the receiving wheel, the anti-slip threads on the spreading wheel pull the fabric to spread the edge, and the spreading wheels on both sides spread the edge in opposite directions, which has a better effect on spreading the edge of the fabric.

[0017] Optionally, a movable frame is slidably mounted on the mounting bracket, and the connecting frame is disposed on the movable frame. The movable frame slides in a direction toward and away from the receiving wheel. An adjusting screw is threadedly mounted on the mounting bracket, and one end of the adjusting screw is rotatably connected to one side of the movable frame.

[0018] By adopting the above technical solution, rotating the adjusting screw drives the moving frame to slide, thereby causing the edge-spreading wheel on the connecting frame to slide towards or away from the receiving wheel, adjusting the distance between the receiving wheel and the edge-spreading wheel, which is suitable for edge-spreading operations on fabrics of different thicknesses.

[0019] Optionally, the mounting frame is provided with guide grooves, which are distributed in a direction perpendicular to the axis of the receiving wheel, and a slider is provided on one side of the movable frame, which slides along the guide grooves.

[0020] By adopting the above technical solution, when the moving frame slides, the slider slides along the guide groove of the mounting frame, thereby limiting the sliding direction of the moving frame.

[0021] Optionally, the movable frame is provided with a guide rod, which is distributed parallel to the guide groove. A spring is sleeved on the guide rod, and the spring is connected to one side of the connecting frame.

[0022] By adopting the above technical solution, when the fabric passes between the spreading wheel and the receiving wheel, the spring pulls the connecting frame, which in turn drives the spreading wheel to press against the fabric. The spreading wheel and the fabric are in elastic contact, which makes it less likely to damage the fabric.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The fabric passes between the spreading roller and the receiving roller on both sides. The spreading roller spreads the fabric edges. The fabric is then transported to the winding roller by the guide roller and wound up. The fabric is spread and wound up again after being expanded. The fabric is less likely to curl when it is wound up.

[0025] 2. Rotating the adjusting screw drives the moving frame to slide, which in turn drives the edge-spreading wheel on the connecting frame to slide towards or away from the receiving wheel, adjusting the distance between the receiving wheel and the edge-spreading wheel. This is suitable for edge-spreading operations on fabrics of different thicknesses.

[0026] 3. The edge-unfolding rollers provide elastic contact with the fabric, minimizing the risk of damaging the fabric. Attached Figure Description

[0032] The present application will be further described in detail below with reference to the accompanying drawings.

[0033] This application discloses a fabric output device for a warp knitting machine, referring to... Figure 1 and Figure 2 The machine includes a frame 1, which is located on one side of the warp knitting machine. Along the fabric transport direction, the frame 1 is provided with an expanding roller 11, a spreading assembly 2, a guide roller 12, and a take-up roller 13. The expanding roller 11, guide roller 12, and take-up roller 13 are all distributed along the width direction of the frame 1. A take-up motor 14 is provided on the frame 1, and the take-up roller 13 is connected to the output shaft of the take-up motor 14. The spreading assembly 2 includes a receiving wheel 21 and a spreading wheel 22. Mounting frames 3 are provided on both sides of the frame 1 in the width direction. The mounting frames 3 are distributed in the vertical direction. The spreading wheel 22 and the receiving wheel 21 are rotatably mounted on the mounting frames 3 and are distributed vertically and parallel to each other. The spreading wheel 22 and the receiving wheel 21 on the two mounting frames 3 are distributed opposite each other. After the warp knitting machine outputs the fabric, it is expanded by the spreading roller 11. The two sides of the fabric pass between the spreading roller 22 and the receiving roller 21. The spreading roller 22 spreads the edges of the fabric. The fabric is then transported by the guide roller 12 to the winding roller 13 for winding. After the fabric is expanded and spread, it is then wound up. The fabric is less likely to curl at the edges when it is wound up.

[0034] Reference Figure 2 and Figure 3 An adjusting component 4 is provided on the frame 1. The adjusting component 4 includes an adjusting motor 41 and an adjusting screw 42. The adjusting screw 42 is rotatably mounted on the frame 1 and distributed along the width direction of the frame 1. The adjusting motor 41 is mounted on the frame 1, and the adjusting screw 42 is connected to the output shaft of the adjusting motor 41. The adjusting screw 42 has two opposite threads. The mounting brackets 3 on both sides are threadedly connected to the adjusting screw 42 at the two threads respectively. A sliding rod 15 is provided on the frame 1. The sliding rod 15 is distributed parallel to the adjusting screw 42, and the mounting brackets 3 are slidably connected to the sliding rod 15. The adjusting motor 41 drives the adjusting screw 42 to rotate, and the adjusting screw 42 drives the mounting brackets 3 on both sides to slide in opposite directions. At the same time, the position of the mounting brackets 3 on both sides is adjusted, which in turn drives the edge-spreading wheels 22 and the receiving wheels 21 on the mounting brackets 3 to move. Adjusting the position of the edge-spreading wheels 22 on both sides is suitable for edge-spreading operations on fabrics of different widths.

[0035] Reference Figure 2 and Figure 3 The mounting frame 3 is equipped with a movable frame 5. A guide groove 31 is vertically formed on one side of the receiving wheel 21 on the mounting frame 3. A slider 51 is located on one side of the movable frame 5, sliding along the guide groove 31. A connecting frame 6 is mounted on the movable frame 5, and the edge-stretching wheel 22 is rotatably mounted on the connecting frame 6. An adjusting screw 32 is threaded vertically onto the mounting frame 3, with its downward-facing end rotatably connected to the upward-facing side of the movable frame 5. Rotating the adjusting screw 32 drives the movable frame 5 to slide, which in turn causes the edge-stretching wheel 22 on the connecting frame 6 to slide towards or away from the receiving wheel 21, adjusting the distance between the receiving wheel 21 and the edge-stretching wheel 22. This is suitable for edge-stretching operations on fabrics of different thicknesses.

[0036] Reference Figure 2 and Figure 3 A guide rod 52 is vertically mounted on the movable frame 5, and a sliding block 61 is mounted on the connecting frame 6. The sliding block 61 is slidably connected to the guide rod 52. A spring 53 is sleeved on the guide rod 52, and the upward-facing end of the spring 53 is connected to the downward-facing side of the sliding block 61. When the fabric passes between the edge-spreading wheel 22 and the receiving wheel 21, the spring 53 pulls the connecting frame 6, thereby causing the edge-spreading wheel 22 to press against the fabric. The edge-spreading wheel 22 and the fabric are in elastic contact, which reduces the risk of damaging the fabric.

[0037] Reference Figure 2 and Figure 3 The edge-spreading wheel 22 is provided with anti-slip threads 221. The anti-slip threads 221 on both sides of the edge-spreading wheel 22 have opposite spiral directions. When the fabric passes between the edge-spreading wheel 22 and the receiving wheel 21, the anti-slip threads 221 on the edge-spreading wheel 22 pull the fabric to spread the edge. The edge-spreading wheels 22 on both sides spread the edge in opposite directions, which has a better edge-spreading effect on the fabric.

[0038] The implementation principle of the fabric output device of the warp knitting machine in this application embodiment is as follows: After the warp knitting machine outputs the fabric, it is expanded by the expansion roller 11. The two sides of the fabric pass between the edge spreading roller 22 and the receiving roller 21. The edge spreading roller 22 on both sides spreads the edges of the fabric. The fabric is transported to the take-up roller 13 by the guide roller 12 and then taken up. After the fabric is expanded and spread, it is taken up again. When the fabric is taken up, it is not easy for the edge to curl.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
