Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, specifically a fabric guiding mechanism for a desizing machine. Background Technology

[0002] Desizing refers to the process of treating fabrics with acids, alkalis, enzymes, etc., to remove the sizing agents added to the warp yarns during weaving, in order to facilitate subsequent processing such as scouring.

[0003] Before weaving, the warp yarns are usually sized (the warp yarns are soaked in sizing solution and then dried) to make the fibers in the yarn stick together and form a thin film on the yarn surface, which facilitates weaving. However, the sizing solution will affect the wettability of the fabric and hinder the contact of chemicals with the fibers during the dyeing and finishing process. Therefore, the fabric is usually desized first. Desizing of cotton fabrics also has the function of removing some impurities from the fibers.

[0004] Desizing is usually performed using a desizing machine. In related technologies, desizing machines include a water tank in which the fabric is acid-washed or alkali-washed. Multiple sets of guide rollers are usually set in the water tank for guiding the fabric. The fabric needs to go up and down around all the guide rollers, which makes the feeding of the fabric quite troublesome. Based on this, a fabric guiding mechanism for a desizing machine is provided. Utility Model Content

[0005] The purpose of this utility model is to provide a fabric guiding mechanism for a desizing machine in order to solve the problems mentioned above.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a desizing machine with a guide fabric mechanism, including a water tank, wherein a feed limiting guide roller and a discharge limiting guide roller are rotatably installed at the front and rear ends of the water tank, and a guide fabric assembly is provided on the inner side of the water tank, the guide fabric assembly being used to realize the “S”-shaped guide fabric operation.

[0007] The guide fabric assembly includes a positioning guide roller, a movable guide roller, and a flipping unit;

[0008] Multiple positioning guide rollers and movable guide rollers are arranged horizontally, and the multiple positioning guide rollers and movable guide rollers are staggered along the waterline, with the movable guide rollers distributed below the positioning guide rollers. The positioning guide rollers and movable guide rollers cooperate to provide material guiding operation for the fabric.

[0009] The flipping unit is used to realize the up-and-down flipping operation of the movable guide roller, which flips the movable guide roller to be above the positioning guide roller to facilitate the feeding operation of the guide cloth assembly.

[0010] As a further embodiment of this utility model: the flipping unit includes a bearing base, a connecting arm, a flipping arm, and an electric push rod;

[0011] The bearing base is fixedly installed on the top side of the water tank, and a rotating shaft that is rotatably connected to the bearing base is fixed on the top side of the connecting arm. The connecting arm is distributed on the inner side of the water tank, and the movable guide roller is rotatably connected to the bottom side of the movable guide roller.

[0012] The connecting arm shaft passes through the bearing base to the outside of the water tank and is fixedly connected to the tilting arm. The tail end of the electric push rod is rotatably connected to the outside of the water tank. The top of the output end of the electric push rod is rotatably connected to the bottom end of the tilting arm. The tilting arm, connecting arm, and movable guide roller are driven to rotate as a whole around the bearing base by the electric push rod, so as to realize the up and down tilting operation of the movable guide roller.

[0013] As a further improvement of this utility model: the number of the flipping units matches the number of the movable guide rollers, and the rotation radius of the connecting arm is less than the distance from the bearing base to the rear positioning guide roller.

The support shaft is slidably engaged with the inner side of the arc-shaped guide rail. The top of the arc-shaped guide rail has an open structure, and the bottom of the arc-shaped guide rail has a sealed structure.

[0017] As a further embodiment of this utility model: the distance between the arc-shaped guide rail and the connecting arm on the side closer to each other is greater than the width of the outer concave portion of the feed limiting guide roller and the discharge limiting guide roller, and the width of the outer concave portion of the feed limiting guide roller and the discharge limiting guide roller is greater than or equal to the width of the fabric.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] By setting up a guide fabric assembly with a flipping unit, the flipping operation of the movable guide roller can be realized. The movable guide roller flips to the top of the water tank, and the side of the movable guide roller is unobstructed from the water tank. This allows the pulling and feeding operation of the fabric to be completed in one step. Afterwards, the movable guide roller flips down and squeezes the fabric, so that the fabric follows a sideways "S" shaped trajectory inside the water tank, thus completing the fabric feeding operation. The operation is simple and convenient. Attached Figure Description

[0025] 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.

[0026] Please see Figures 1-4 In this embodiment of the present invention, a desizing machine has a fabric guiding mechanism, including a water tank 1. The front and rear ends of the water tank 1 are respectively rotatably mounted with a feed limiting guide roller 2 and a discharge limiting guide roller 3. A fabric guiding assembly 4 is provided on the inner side of the water tank 1. The fabric guiding assembly 4 is used to realize the "S"-shaped material guiding operation of the fabric 5.

[0027] The guide fabric assembly 4 includes a positioning guide roller 401, a movable guide roller 404, and a flipping unit;

[0028] Multiple positioning guide rollers 401 and movable guide rollers 404 are arranged in the horizontal direction. The multiple positioning guide rollers 401 and movable guide rollers 404 are staggered along the water, and the movable guide rollers 404 are distributed below the positioning guide rollers 401. The positioning guide rollers 401 and movable guide rollers 404 cooperate to provide material guiding operation for the fabric 5.

[0029] The flipping unit is used to realize the up-and-down flipping operation of the movable guide roller 404. The movable guide roller 404 is flipped to be above the positioning guide roller 401 to facilitate the feeding operation of the guide cloth assembly 4.

[0030] The flipping unit includes a bearing base 402, a connecting arm 403, a flipping arm 406, and an electric push rod 407;

[0031] The bearing base 402 is fixedly installed on the top side of the water tank 1. The top side of the connecting arm 403 is fixed with a rotating shaft that is rotatably connected to the bearing base 402. The connecting arm 403 is distributed on the inner side of the water tank 1. The movable guide roller 404 is rotatably connected to the bottom side of the movable guide roller 404.

[0032] The connecting arm 403's rotating shaft passes through the bearing base 402 to the outside of the water tank 1 and is fixedly connected to the tilting arm 406. The tail end of the electric push rod 407's housing is rotatably connected to the outside of the water tank 1. The top of the output end of the electric push rod 407 is rotatably connected to the bottom end of the tilting arm 406. The electric push rod 407 drives the tilting arm 406, the connecting arm 403, and the movable guide roller 404 to rotate as a whole around the bearing base 402, thereby realizing the up-and-down tilting operation of the movable guide roller 404.

[0033] The number of flipping units matches the number of movable guide rollers 404, and the rotation radius of the connecting arm 403 is less than the distance from the bearing base 402 to the rear positioning guide roller 401.

[0034] In this embodiment, the operation steps for feeding fabric 4 are as follows:

[0035] The initial state of the movable guide roller 404 is at its lowest position by default. At this time, the electric push rod 407 is started first. The electric push rod 407 pushes the flipping arm 406 to rotate upward. The flipping arm 406 drives the connecting arm 403 and the movable guide roller 404 to rotate upward, so that the movable guide roller 404 can be flipped from the lowest position to the highest position.

[0036] At this time, the movable guide roller 404 is located above the water tank 1. There is no obstruction between the side of the movable guide roller 404 away from the connecting arm 403 and the upper surface of the water tank 1. In this way, the fabric 5 can be directly pulled from the feed limiting guide roller 2 to the discharge limiting guide roller 3, so that the fabric 5 passes through the upper part of the positioning guide roller 401 and the lower part of the movable guide roller 404, and finally overlaps the surface of the discharge limiting guide roller 3. During this process, the unobstructed structure between the side of the movable guide roller 404 and the water tank 1 makes the operation of pulling the fabric 5 to move complete in one step, which is simple and convenient.

[0037] Then, the electric push rod 407 is reversed to make the movable guide roller 404 flip downward. The movable guide roller 404 contacts the fabric 5 and simultaneously squeezes the fabric 5 down to a position near the bottom inside the water tank 1. Thus, the part of the fabric 5 in the water tank 1 forms a sideways "S" shaped trajectory, thus completing the feeding operation of the fabric 5.

[0038] Please refer to this carefully. Figures 1-4 The guide cloth assembly 4 also includes a support shaft 405 and an arc-shaped guide rail 408;

[0039] The support shaft 405 is fixed to the side of the movable guide roller 404 away from the connecting arm 403;

[0040] The arc-shaped guide rail 408 is fixed to the inner wall of the water tank 1 on the side away from the bearing base 402. The support shaft 405 is slidably engaged with the inner side of the arc-shaped guide rail 408. The top of the arc-shaped guide rail 408 has an open structure, and the bottom of the arc-shaped guide rail 408 has a sealed structure.

[0041] In this embodiment, it should be noted that the center of the arc-shaped guide rail 408 is coaxial with the center of the rotating shaft of the connecting arm 403, and the radius of the arc-shaped guide rail 408 matches the rotation radius of the support shaft 405.

[0042] When the movable guide roller 404 is in the lowest position, the support shaft 405 is in contact with the bottom of the arc-shaped guide rail 408. The arc-shaped guide rail 408 is used to provide support for the movable guide roller 404 and the support shaft 405, so that the forces on both sides of the movable guide roller 404 are balanced.

[0043] During the rotation of the movable guide roller 404, the support shaft 405 moves along the trajectory of the inner wall of the arc-shaped guide rail 408, and the opening structure at the top of the arc-shaped guide rail 408 does not affect the movement of the support shaft 405.

[0044] Please refer to this carefully. Figures 1-4 The distance between the arc-shaped guide rail 408 and the connecting arm 403 on the side closer to each other is greater than the width of the outer concave part of the feed limiting guide roller 2 and the discharge limiting guide roller 3, and the width of the outer concave part of the feed limiting guide roller 2 and the discharge limiting guide roller 3 is greater than or equal to the width of the fabric 5.

[0045] In this embodiment, the feed limiting guide roller 2 and the discharge limiting guide roller 3 can provide a limit for the fabric 5, so that the fabric 5 will not come into contact with or rub against the connecting arm 403 and the arc-shaped guide rail 408.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
