Description

Technical Field

[0001] The utility model relates to the field of fabric processing equipment, in particular to a drawing-off machine for dyeing and finishing fabrics. Background Art

[0002] The dyeing and finishing process is to reproduce the favorite colors and patterns perfectly on the fabric by using dyeing and finishing technology, so that the fabric is more artistic. Before the fabric undergoes the dyeing and finishing process, the rolled fabric needs to be opened first, and the machine used is the uncoiler.

[0003] The utility model with the publication number CN207903580U discloses an uncoiler, which includes a frame, a supporting roller, and a driving roller. A transmission roller is rotatably connected to the frame at the position of the supporting roller. A transmission belt for supporting the fabric is arranged between the transmission roller and the driving roller. A pressing device for pressing the fabric onto the transmission belt is also arranged on the frame.

[0004] For the uncoiler in the above technical solution, the fabric is transported by the transmission belt and pressed onto the transmission belt by the pressing device. The pressing device increases the friction between the fabric and the transmission belt, which easily causes damage to the fabric during the process of unwinding the rolled fabric, makes the surface of the fabric fuzz and shed hair, and increases the possibility of generating flying flocs during the process, affecting the cleanliness of production. Utility Model Content

[0005] In order to reduce the possibility of generating flying flocs during the drawing-off process, the present application provides a drawing-off machine for dyeing and finishing fabrics.

[0006] The drawing-off machine for dyeing and finishing fabrics provided by the present application adopts the following technical solutions:

[0007] A drawing-off machine for dyeing and finishing fabrics includes a frame, a drawing-off mechanism for fabric drawing-off, and a fabric arranging mechanism for fabric arrangement. The drawing-off mechanism includes a plurality of rotating rollers, a plurality of limiting rollers, and a first driving member. The plurality of rotating rollers are respectively rotatably connected to the frame. The plurality of limiting rollers are respectively rotatably connected to the frame along the rotation direction of the rotating rollers. The first driving member is used to drive the rotation of the plurality of rotating rollers. When the drawing-off machine is in a working state, the plurality of rotating rollers always abut against the rolled fabric, and the open end of the rolled fabric passes through between two rotating rollers close to the fabric arranging mechanism, and some of the limiting rollers respectively abut against the rolled fabric.

[0008] By adopting the above technical solution, the first driving member drives the rotation of a plurality of rotating rods, so as to drive the wound fabric abutted against the rotating rods to rotate, and move the open end of the wound fabric between the two rotating rods, and perform the operation of removing the loop from the wound fabric. When the wound fabric rotates, it drives the limiting rods abutted against the wound fabric to rotate together, reducing the friction force on the wound fabric, thereby reducing the possibility of generating flying flocs during the process of removing the loop. And after removing the loop, the uncoiling mechanism sorts the fabric after removing the loop, reducing the possibility of the fabric after removing the loop being randomly stacked, thus reducing the possibility of causing a messy working environment.

[0009] Preferably, a plurality of the limiting rods are arranged in a "V" shape.

[0010] By adopting the above technical solution, when the wound fabric removes the loop, the diameter of the wound fabric gradually becomes smaller, causing a plurality of limiting rods to be arranged in a "V" shape. When removing the loop from the wound fabric, there is always a limiting rod abutted against the wound fabric, thereby reducing the possibility of generating flying flocs during the process of removing the loop.

[0011] Preferably, the uncoiling mechanism includes a swing frame and a second driving member. The swing frame is rotatably connected to the frame along the rotation direction of the rotating rod. A guiding groove is provided on the swing frame. When the uncoiling machine is in the working state, the open end of the wound fabric passes through the guiding groove.

[0012] By adopting the above technical solution, the second driving member drives the swing frame to swing, so that the part of the wound fabric that has removed the loop falls out of the swing frame and is folded back and forth to sort the fabric after removing the loop.

[0013] Preferably, the guiding groove is tapered from the end close to the rotating rod to the end far from the rotating rod.

[0014] By adopting the above technical solution, it guides the fabric that has removed the loop, reducing the possibility of the fabric that has removed the loop falling out of the swing frame.

[0015] Preferably, a speed-limiting rod is provided on the frame. The speed-limiting rod is located between the swing frame and the rotating rod, and the speed-limiting rod abuts against the fabric.

[0016] By adopting the above technical solution, the speed-limiting rod plays a role in guiding and speed-limiting the falling of the part of the fabric that has removed the loop, reducing the possibility of the part of the fabric that has removed the loop falling into the swing frame; and reducing the possibility of the fabric removing the loop too fast due to inertia and gravity and stacking in the swing frame. The speed-limiting rod also plays a role in preventing the part of the fabric that has removed the loop from being looped back.

[0017] Preferably, the second driving member includes a second motor, a swing rod and a connecting rod. One end of the connecting rod is rotatably connected to the swing frame along the swinging direction of the swing frame. The second motor is arranged on the machine frame. One end of the swing rod is fixedly connected to the output shaft of the second motor, and the end of the swing rod away from the second motor is rotatably connected to the connecting rod.

[0018] By adopting the above technical solution, according to the principle of the hinge four-bar mechanism, when the second motor drives the swing rod to rotate, the connecting rod pushes and pulls the swing frame back and forth, so that the swing frame swings.

[0019] Preferably, a plurality of limiting plates are slidably connected to the machine frame. When the unwinding machine is in the working state, the plurality of limiting plates respectively abut against both ends in the axial direction of the wound fabric.

[0020] By adopting the above technical solution, the plurality of limiting plates can limit both ends in the axial direction of the wound fabric, reducing the possibility that the wound fabric deviates along its axial direction during the unwinding process.

[0021] Preferably, bolts are respectively inserted through and threadedly connected to the plurality of limiting plates, and one ends of the plurality of bolts respectively abut against the machine frame.

[0022] By adopting the above technical solution, rotate the bolts so that the bolts abut against the machine frame to limit the sliding of the limiting plates, reducing the possibility that the wound fabric deviates due to the sliding of the limiting plates when unwinding the wound fabric.

[0023] The technical effects of the present utility model are mainly reflected in the following aspects:

[0024] 1. By providing an unwinding mechanism and a fabric aligning mechanism, the first driving member drives the rotation of a plurality of rollers, so that the wound fabric abutted against the rollers rotates, and the open end of the wound fabric moves between the two rollers to perform an unwinding operation on the wound fabric. When the wound fabric rotates, it drives the limiting rollers abutted against the wound fabric to rotate together, reducing the frictional force on the wound fabric, thereby reducing the possibility of generating flying flocs during the unwinding process. And after unwinding, the fabric aligning mechanism arranges the unwound fabric, reducing the possibility that the unwound fabric is randomly stacked, thus reducing the possibility of causing a messy working environment;

[0025] 2. By providing a swing frame and a second driving member, the second driving member drives the swing frame to swing, so that the unwound part of the wound fabric falls out of the swing frame and is folded back and forth to arrange the unwound fabric;

[0026] 3. The utility model sets a speed limiting stick, which guides and limits the falling of the unlooped portion of the fabric, thereby reducing the possibility of the unlooped portion of the fabric falling into the swing frame; and reduces the possibility of the fabric stacking in the swing frame due to inertia and gravity due to excessive unlooping speed. The speed limiting stick also prevents the unlooped portion of the fabric from circling back. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The open end of the cloth roll of the rotating roller 21 is arranged between the two rotating rollers, and some of the limiting rollers 22 are respectively in contact with the rolled cloth.

[0034] Reference Figure 2, the first driving member 23 includes a first motor 231. Two rotating rods 21 are respectively coaxially and fixedly connected with first sprockets 232. A first transmission chain 235 is simultaneously meshed and connected to the two first sprockets 232. The first motor 231 is fixedly connected to the frame 1. One end of the output shaft of the first motor 231 is coaxially and fixedly connected with a second sprocket 233. A third sprocket 234 is coaxially and fixedly connected to any one of the first sprockets 232. A second transmission chain 236 is simultaneously meshed and connected to the second sprocket 233 and the third sprocket 234. When the first motor 231 drives the second sprocket 233 to rotate, through the meshing connection of the second transmission chain 236, the third sprocket 234 is driven to rotate, and the first sprocket 232 coaxial with the third sprocket 234 rotates. Through the meshing connection of the first transmission chain 235, the two first sprockets 232 rotate in the same direction simultaneously.

[0035] Refer to Figures 1-4 , through the first driving member 23 driving the rotation of several rotating rods 21, the rolled fabric abutted against the rotating rods 21 is rotated, so that the open end of the rolled fabric moves between the two rotating rods 21, and the uncoiling operation of the rolled fabric is carried out. When the rolled fabric rotates, the limiting rods 22 abutted against the rolled fabric rotate together, reducing the friction force on the rolled fabric, thereby reducing the possibility of generating flying flocs during the uncoiling process. And after uncoiling, the uncoiled fabric is sorted by the fabric sorting mechanism 3, reducing the possibility of the uncoiled fabric being randomly stacked, thereby reducing the possibility of causing a messy working environment. When the rolled fabric is uncoiled, the diameter of the rolled fabric gradually becomes smaller, making several limiting rods 22 arranged in a "V" shape, so that when the rolled fabric is uncoiled, there is always a limiting rod 22 abutted against the rolled fabric, thereby reducing the possibility of generating flying flocs during the uncoiling process.

[0036] Refer to Figures 1-5 , the fabric sorting mechanism 3 includes a swing frame 31 and a second driving member 32. The swing frame 31 is rotatably connected to the frame 1 along the rotation direction of the rotating rod 21. A guiding groove 311 is formed on the swing frame 31. The guiding groove 311 is arranged in a gradually shrinking shape from the end close to the rotating rod 21 to the end far from the rotating rod 21. When the uncoiler is in the working state, the open end of the rolled fabric passes through the guiding groove 311. The second driving member 32 drives the swing frame 31 to swing, so that the uncoiled part of the rolled fabric falls out of the swing frame 31 and is folded back and forth to sort the uncoiled fabric. The guiding groove 311 is arranged in a gradually shrinking shape to guide the uncoiled part of the fabric, reducing the possibility of the uncoiled part of the fabric falling out of the swing frame 31.

[0037] Refer to Figures 1-5, the second driving member 32 includes a second motor 321, a swing rod 322 and a connecting rod 323. One end of the connecting rod 323 is rotatably connected to the swing frame 31 along the swinging direction of the swing frame 31. The second motor 321 is arranged on the frame 1. One end of the swing rod 322 is fixedly connected to the output shaft of the second motor 321. The end of the swing rod 322 away from the second motor 321 is rotatably connected to the connecting rod 323. According to the principle of the hinge four-bar mechanism, when the second motor 321 drives the swing rod 322 to rotate, the connecting rod 323 pushes and pulls the swing frame 31 back and forth, so that the swing frame 31 swings.

[0038] Referring to Figures 1-5 , a speed-limiting rod 11 is fixedly connected to the frame 1. The central axis of the speed-limiting rod 11 is parallel to the central axis of the rotating rod 21. The speed-limiting rod 11 is located between the swing frame 31 and the rotating rod 21 and is located between two rotating rods 21. The speed-limiting rod 11 abuts against the fabric. The speed-limiting rod 11 plays a role in guiding and speed-limiting the falling of the uncoiled part of the fabric, increasing the possibility that the uncoiled part of the fabric falls into the swing frame 31; and reducing the possibility that the fabric uncoils too fast due to inertia and gravity and the fabric stacks in the swing frame 31. The speed-limiting rod 11 also plays a role in preventing the uncoiled part of the fabric from being looped back.

[0039] Referring to Figures 1-4 , two limiting plates 12 are slidably connected to the frame 1. The end of the limiting plate 12 away from the rotating rod 21 to the end close to the rotating rod 21 is tapered, so as not to affect the rotation of the rotating rod 21 and the limiting rod 22. When the uncoiling machine is in the working state, the two limiting plates 12 respectively abut against both ends in the axial direction of the coiled fabric. The two limiting plates 12 can limit both ends in the axial direction of the coiled fabric, reducing the possibility that the coiled fabric deviates along its axial direction during the uncoiling process. Bolts 121 are respectively passed through and threadedly connected to the two limiting plates 12. One ends of a plurality of bolts 121 respectively abut against the frame 1. Rotate the bolts 121 so that the bolts 121 abut against the frame 1 to limit the sliding of the limiting plates 12, reducing the possibility that the coiled fabric deviates due to the sliding of the limiting plates 12 when the coiled fabric is uncoiled.

[0040] Of course, the above are only typical examples of the present application. In addition, the present application can also have many other specific implementation manners. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present application.
