Description

Technical Field

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

[0002] Curtains require flame retardancy and UV protection in many applications. To achieve flame retardancy, the fabric is finished using a coating machine.

[0003] In the prior art, reference can be made to Chinese utility model patent with authorization announcement number CN212576690U, which discloses an automatic width adjustment device for a coating machine. The device includes a frame, on which a coating roller and a pressure roller are mounted. Both ends of the coating roller and the pressure roller are rotatably connected to the frame bodies on both sides of the frame. A liquid injection pipe is fixed to the frame body at the top of the frame. A screw is also mounted on the frame, with two sections of external threads in opposite directions. Both ends of the screw are rotatably connected to the frame bodies on both sides of the frame. Two first movable blocks are provided on each of the two threaded sections of the screw. The screw passes through and is threadedly connected to the first movable blocks. A partition is fixed to the bottom surface of each first movable block. This automatic width adjustment device for the coating machine facilitates automatic adjustment of the coating width on the surface of the coating roller, ensuring that the coating width matches the fabric width and reducing paint waste.

[0004] When the fabric is transported directly from the take-up roller to the coating roller for coating, wrinkles are likely to exist on the fabric surface. These wrinkles are prone to not being coated properly, resulting in uneven coating and poor coating effect on the fabric. Utility Model Content

[0005] To address the problem of uneven coating caused by insufficient coating when there are wrinkles on the fabric surface, this application provides a fabric feeding device for a coating machine.

[0006] The coating machine feeding device provided in this application adopts the following technical solution: A fabric feeding device for a coating machine includes a frame disposed on one side of the coating machine. A transport table and a fabric feeding roller are mounted on the frame. A limiting mechanism is disposed on one side of the fabric feeding roller on the frame. The limiting mechanism includes a limiting roller and a limiting member. Mounting frames are disposed on opposite sides of the transport table on the frame. The limiting roller is rotatably mounted on the mounting frames. The limiting member is disposed on the mounting frames and located at the limiting roller, and is used to adjust the pressure of the limiting roller. A spreading plate is disposed on the upper side of the transport table on the frame. A clamping member for pushing the spreading plate is disposed on the upper side of the spreading plate on the frame.

[0007] By adopting the above technical solution, the fabric is fed by the feed roller, and the two sides of the fabric are limited and pulled by the edge limiting roller. The limiting component adjusts the edge limiting roller. Then, at the spreading plate, the pressing component pushes the spreading plate to flatten the fabric. After that, it is conveyed to the coating machine for coating operation. The fabric surface has fewer wrinkles and the fabric coating effect is better.

[0008] Optionally, the limiting component includes an adjusting screw and a slider. The mounting frame is provided with a sliding groove. The slider is slidably installed in the sliding groove. The mounting frame is slidably installed with a top plate in the sliding groove. The adjusting screw is threaded on the mounting frame and rotatably connected to the top plate. The top plate is connected to the slider. The limiting roller is rotatably installed at the slider.

[0009] By adopting the above technical solution, rotating the adjusting screw drives the slider to move up and down, adjusting the position of the edge-limiting roller, which is suitable for edge-limiting and pressing of fabrics of different thicknesses.

[0010] Optionally, a first screw is threaded onto the slider, and a rotating rod is rotatably mounted on one end of the first screw, the rotating rod being rotatably connected to one end of the edge-limiting roller.

[0011] By adopting the above technical solution, rotating the first screw drives the rotating rod to move, thereby adjusting the position of the edge-limiting roller. Adjusting the position of the edge-limiting roller on the transport table is suitable for edge-limiting and pressing of fabrics of different widths.

[0012] Optionally, a second spring and a third spring are provided on opposite sides of the slider, with one end of the second spring connected to the top plate and one end of the third spring connected to the bottom wall of the slide groove.

[0013] By adopting the above technical solution, springs are provided on both the upper and lower sides of the slider. The pressure of the slider is adjusted by the second spring and the third spring, which reduces the problem of fabric damage caused by the edge-limiting roller pressing the side of the fabric when the edge is limited.

[0014] Optionally, the edge limiting roller is provided with anti-slip strips, which are spirally wound around the edge limiting roller, and the anti-slip strips on opposite sides of the edge limiting roller are wound in opposite directions.

[0015] By adopting the above technical solution, the anti-slip strip of the edge limiting roller is pressed tightly onto the fabric, and the edge limiting rollers on both sides pull the fabric in opposite directions, resulting in a better edge pulling effect on the fabric.

[0016] Optionally, one end of the limiting roller is provided with an installation groove, the rotating rod is connected to the limiting roller at the installation groove, and one end of the rotating rod is provided with a first spring, one end of the first spring being connected to the limiting roller.

[0017] By adopting the above technical solution, the rotating rod presses against the first spring, which in turn presses against the edge-limiting roller. The edge-limiting roller is elastically pressed against the roller in the axial direction, reducing the problem of damage to the fabric when the edge-limiting roller pulls the edge.

[0018] Optionally, the clamping element includes a clamping rod and a clamping spring. Support frames are provided on opposite sides of the conveyor platform on the frame. The clamping rod is slidably mounted on the support frame. The flat plate is connected to one end of the clamping rod. The clamping spring is sleeved on the clamping rod and one end of the clamping spring is connected to one side of the flat plate.

[0019] By adopting the above technical solution, the clamping spring pushes the clamping rod to drive the flat plate to press against the surface of the fabric, resulting in a better flattening effect on the fabric.

[0020] Optionally, a limit ring is threadedly installed on the end of the abutting rod opposite to the abutting spring, and one side of the limit ring abuts against the support frame.

[0021] By adopting the above technical solution, the position of the clamping rod can be adjusted by rotating the limiting ring, thereby adjusting the position of the spreading plate, which is suitable for spreading fabrics of different thicknesses.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The fabric is fed through the feed roller. After feeding, the two sides of the fabric are limited and pulled by the edge limiting roller. The limiting component adjusts the edge limiting roller. Then, the fabric passes through the spreading plate, where the pressing component pushes the spreading plate to flatten the fabric. The fabric is then conveyed to the coating machine for coating. The fabric surface has fewer wrinkles and the coating effect is better. 2. Rotating the adjusting screw drives the mounting bracket to move up and down, which in turn drives the slider to move up and down, adjusting the position of the edge-limiting roller. This is suitable for edge-limiting and pressing of fabrics of different thicknesses. 3. Rotate the limit ring to adjust the position of the clamping rod, and then adjust the position of the spreading plate. This is suitable for spreading fabrics of different thicknesses.

[0029] The present application will be further described in detail below with reference to the accompanying drawings.

[0030] This application discloses a fabric feeding device for a coating machine, referring to... Figure 1 The system includes a frame 1, which is located on one side of the coating machine. The frame 1 is equipped with a transport platform 2 and a feed roller 3. The feed roller 3 is rotatably mounted on the transport platform 2 and located on one side of the transport platform 2. A limiting edge mechanism 4 is provided on the transport platform 2 on one side of the feed roller 3. The limiting edge mechanism 4 includes a limiting edge roller 41 and a limiting element 42. Mounting frames 21 are provided on opposite sides of the transport platform 2. The limiting edge roller 41 is mounted on the mounting frame 21, and the limiting element 42 is mounted on the mounting frame 21 and connected to the limiting edge roller 41. The fabric is fed through the feed roller 3 and transported along the transport platform 2. The two sides of the fabric are limited and pulled by the limiting edge roller 41, and the limiting element 42 adjusts the limiting edge roller 41.

[0031] Reference Figure 1 A spreading plate 22 is provided on the side of the limiting roller 41 away from the feed roller 3 on the transport table 2. An abutting member 5 is provided on the opposite sides of the transport table 2. The spreading plate 22 is connected to the abutting member 5. After the fabric passes through the spreading plate 22, the abutting member 5 pushes the spreading plate 22 to flatten the fabric and then it is transported to the coating machine for coating operation. The fabric surface has fewer wrinkles.

[0032] Reference Figure 2The limiting component 42 includes an adjusting screw 421 and a slider 422. A slide groove 211 is provided on the mounting frame 21. The slider 422 is vertically slidably installed in the slide groove 211 of the mounting frame 21. The limiting roller 41 is connected to the slider 422. The adjusting screw 421 is vertically threaded on the mounting frame 21, and one end of the adjusting screw 421 is located in the slide groove 211. A top plate 423 is slidably installed in the slide groove 211. The downward end of the adjusting screw 421 is rotatably connected to the upward side of the top plate 423. A second spring 424 is provided on the upward side of the slider 422. The upward end of the second spring 424 is connected to the downward side of the top plate 423. A third spring 425 is provided on the downward side of the slider 422. The downward end of the third spring 425 is connected to the bottom wall of the slide groove 211. Rotating the adjusting screw 421 causes the slider 422 to move up and down, adjusting the position of the edge-limiting roller 41, which is suitable for edge-limiting and pressing of fabrics of different thicknesses.

[0033] Reference Figure 2 and Figure 3 A first screw 426 is horizontally threaded onto the slider 422. A rotating rod 427 is rotatably mounted on one end of the first screw 426. A mounting groove 411 is provided at one end of the edge-limiting roller 41. One end of the rotating rod 427 is slidably connected to the edge-limiting roller 41 at the mounting groove 411. A first spring 428 is provided at the end of the rotating rod 427 opposite to the first screw 426 and located at the mounting groove 411. The end of the first spring 428 opposite to the rotating rod 427 is connected to the bottom wall of the edge-limiting roller 41 at the mounting groove 411. Rotating the first screw 426 moves the rotating rod 427, thereby adjusting the position of the edge-limiting roller 41. Adjusting the position of the edge-limiting roller 41 on the transport table 2 is suitable for edge-limiting and pressing fabrics of different widths.

[0034] Reference Figure 3 The edge-limiting roller 41 is provided with anti-slip strips 412, which are spirally wound around the edge-limiting roller 41. The anti-slip strips 412 on the opposite sides of the edge-limiting roller 41 are wound in opposite directions. The opposite sides of the edge-limiting roller 41 pull the fabric in opposite directions, which has a better edge-pulling effect on the fabric.

[0035] Reference Figure 4 The clamping component 5 includes a clamping rod 51 and a clamping spring 52. The transport table 2 is located on one side of the limiting roller 41 and on opposite sides of the support frame 23. The clamping rod 51 is vertically slidably mounted on the support frame 23. The lower side of the clamping rod 51 is connected to the spreading plate 22. The spreading plate 22 is horizontally arranged along the width direction of the transport table 2. The clamping spring 52 is sleeved on the clamping rod 51. The lower end of the clamping spring 52 is connected to the spreading plate 22, and the upper end of the clamping spring 52 is connected to one side of the support frame 23. The clamping spring 52 pushes the clamping rod 51 to drive the spreading plate 22 to press against the surface of the fabric, resulting in a better flattening effect on the fabric.

[0036] Reference Figure 4 The clamping rod 51 is located on the upper side of the support frame 23 and is equipped with a limiting ring 53. The limiting ring 53 is threadedly connected to the clamping rod 51. Rotating the limiting ring 53 adjusts the position of the clamping rod 51 and thus adjusts the position of the spreading plate 22. It is suitable for spreading fabrics of different thicknesses.

[0037] The implementation principle of the fabric feeding device of the coating machine in this application embodiment is as follows: the fabric is fed in by the feeding roller 3, the two sides of the fabric are limited and pulled by the edge limiting roller 41, and then flattened by the spreading plate 22, so that there are fewer wrinkles on the fabric.

[0038] Rotating the adjusting screw 421 causes the slider 422 to move up and down, adjusting the position of the edge-limiting roller 41, which is suitable for edge-limiting and pressing of fabrics of different thicknesses.

[0039] Rotating the first screw 426 drives the rotating rod 427 to move, which in turn drives the position adjustment of the edge limiting roller 41. Adjusting the position of the edge limiting roller 41 on the transport table 2 is suitable for edge limiting and pressing of fabrics of different widths.

[0040] 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.
