Description

[Technical Field]

[0001] This utility model relates to the field of fabric winding machine technology, and in particular to a balance roller and fabric winding machine. [Background Technology]

[0002] When using supercritical carbon dioxide anhydrous dyeing technology, the fabric tension of the winding machine needs to be balanced before it is loaded onto the yarn bobbin to ensure that the fabric is evenly and smoothly distributed, avoiding wrinkles, excessive tightness or looseness at both ends, and thus ensuring that the yarn bobbin and fabric roll are dyed evenly.

[0003] Traditional fabric winding machines have fixed rollers at both ends, which makes it impossible to achieve tension balance on the fabric surface during use, and also makes it impossible to ensure that the fabric is fed evenly and flat, thus affecting the waterless dyeing effect. In view of the above-mentioned problems, the inventors of this case conducted in-depth research on this issue, resulting in this case. [Utility Model Content]

[0004] The technical problem to be solved by this utility model is to provide a balance roller and a fabric winding machine, which solves the problem that existing fabric winding machines cannot achieve tension balance on the fabric surface during use, nor can they ensure that the fabric is evenly and flatly loaded, thus affecting the waterless dyeing effect.

[0005] This utility model is implemented as follows:

[0006] In a first aspect, a balancing roller includes a roller body having a roller surface, a frame, bearings, a shaft core, and a lifting mechanism. The roller body is rotatably disposed outside the shaft core via the bearings. One end of the shaft core extends to the outside of the roller body to form a fixed edge end, and the other end of the shaft core extends to the outside of the roller body to form a non-fixed edge end. The fixed edge end is hinged to the frame, and the non-fixed edge end is connected to the frame via the lifting mechanism. The lifting mechanism drives the non-fixed edge end to adjust up and down to achieve the tension of the fabric surface on the balancing roller surface.

[0007] Furthermore, the lifting mechanism is a lifting cylinder connected between the frame and the non-fixed-side end.

[0008] Furthermore, the stroke of the lifting cylinder is 50-100mm.

[0009] Furthermore, the frame includes a first machine frame, the top of which is provided with a slide rail along the vertical direction; the non-fixed end of the shaft core is provided with a shaft core base, the shaft core base is slidably assembled with the slide rail, and a lifting mechanism is provided on the first machine frame, and the movable end of the lifting mechanism is rotatably connected to the shaft core base.

[0010] Furthermore, the frame also includes a second machine stand, the top of which is provided with a support column, and the fixed end is hinged to the support column.

[0011] Furthermore, the slide rail is made of channel steel.

[0012] Furthermore, both ends of the roller are rotatably connected to the shaft core via bearings.

[0013] Furthermore, it also includes an infrared edge stabilizer set at the edge.

[0014] Secondly, a fabric winding machine employing the aforementioned balance roller.

[0015] By adopting the technical solution of this utility model, at least the following beneficial effects are achieved:

[0016] This invention employs a roller mounted on the outside of a shaft core via bearings. A fixed-edge end is formed at one end of the shaft core and hinged to the frame, with an infrared edge stabilizer installed thereon. Simultaneously, a non-fixed-edge end is formed at the other end of the shaft core and connected to the frame via a lifting mechanism. In practical use, the infrared edge stabilizer can fix one side of the fabric passing over the roller, ensuring neat fabric edge winding. Simultaneously, the roller can rotate flexibly relative to the shaft core, allowing the roller surface to smoothly transport the fabric. Furthermore, the lifting mechanism can adjust the non-fixed-edge end up and down, balancing the fabric tension on the roller surface. Therefore, this invention effectively balances fabric tension, ensuring uniform and flat fabric application. It effectively overcomes problems such as uneven fabric winding tightness, unevenness, and insufficient carbon dioxide flow rate and concentration at both ends due to fabric roll fraying, thus guaranteeing an anhydrous dyeing effect.

[0030] Example 1

[0031] Please see Figures 1 to 2 As shown, a preferred embodiment of the present invention provides a balancing roller 100. The balancing roller 100 includes a roller body 1 with a roller surface 11, a frame, a bearing 3, a shaft core 4, and a lifting mechanism 5. The roller body 1 is rotatably mounted outside the shaft core 4 via the bearing 3, allowing the roller body 1 to rotate flexibly relative to the shaft core 4. One end of the shaft core 4 extends to the outside of the roller body 1 to form a fixed edge end 41, and the other end of the shaft core 4 extends to the outside of the roller body 1 to form a non-fixed edge end 42. The fixed edge end 41 is hinged to the frame, allowing the fixed edge end 41 to rotate relative to the frame. The non-fixed edge end 42 is connected to the frame via the lifting mechanism 5, and the lifting mechanism 5 drives the non-fixed edge end 42 to adjust up and down to balance the tension of the fabric on the roller surface 11.

[0032] In one specific embodiment of this utility model, the lifting mechanism 5 is a lifting cylinder connected between the frame and the non-fixed edge end 42, so as to use the extension and retraction movement of the lifting cylinder to drive the non-fixed edge end 42 to be adjusted up and down.

[0033] Furthermore, the stroke of the lifting cylinder is 50-100mm. In specific implementations of this invention, the stroke of the lifting cylinder can be adjusted to 50-100mm by adjusting the inlet and outlet valves of the lifting cylinder. This allows the lifting cylinder to have more suitable thrust and speed, thereby better meeting the requirements of anhydrous dyeing.

[0034] In a preferred embodiment of the present invention, the frame includes a first machine frame 21, and a slide rail 211 is provided on the top of the first machine frame 21 along the vertical direction; the non-fixed edge end 42 of the shaft core 4 is provided with a shaft core base 421, and the shaft core base 421 is slidably assembled with the slide rail 211 so that the shaft core base 421 can slide up and down along the slide rail 211; the lifting mechanism 5 is provided on the first machine frame 21, and the movable end of the lifting mechanism 5 is rotatably connected to the shaft core base 421 so that the lifting mechanism 5 can drive the shaft core base 421 to slide up and down along the slide rail 211.

[0035] In one specific embodiment of this utility model, the slide rail 211 is a channel steel slide rail. In this utility model, because the fixed end 41 of the shaft core 4 is hinged to the frame and cannot move up and down, the shaft core base 421 cannot move linearly up and down relative to the channel steel slide rail. At the same time, the stroke of the lifting mechanism 5 is relatively short (between 50-100mm). Therefore, in a specific implementation of this utility model, a slide groove 2111 is formed on the channel steel slide rail along the vertical direction, and a slider 4211 that cooperates with the slide groove 2111 is provided on the shaft core base 421. The width of the slide groove 2111 is greater than the width of the slider 4211, so that the slider 4211 can move up and down along the slide groove 2111 and also move along the width direction.

[0036] In a preferred embodiment of this invention, the frame further includes a second machine stand 22, with a supporting column 221 at its top. A fixed end 41 is hinged to the supporting column 221, allowing the fixed end 41 to rotate relative to the supporting column 221. In a specific implementation of this invention, the fixed end 41 is hinged to the supporting column 221 via a hinge shaft 411.

[0037] In a preferred embodiment of the present invention, both ends of the roller body 1 are rotatably connected to the shaft core 4 via bearings 3, so as to ensure that the roller body 1 can rotate smoothly relative to the shaft core 4.

[0038] In a preferred embodiment of this invention, the balance roller 100 further includes an infrared edge fixer 6 disposed at the edge-fixing end 41. During operation, the balance roller 100 of this invention utilizes the infrared edge fixer 6 to fix one side of the fabric surface, ensuring that the fabric edge is neatly rolled up.

[0039] This invention employs a roller body 1 rotatably mounted outside a shaft core 4 via a bearing 3. A fixed-edge end 41 is formed at one end of the shaft core 4 and hinged to the frame, with an infrared edge-fixing device 6 installed at the fixed-edge end 41. Simultaneously, a non-fixed-edge end 42 is formed at the other end of the shaft core 4 and connected to the frame via a lifting mechanism 5. This allows for the following in practical use: firstly, the infrared edge-fixing device 6 can fix one side of the fabric surface passing through the roller surface 11, ensuring a neat edge roll; secondly, the roller body 1 can rotate flexibly relative to the shaft core 4, enabling… The roller surface 11 of the roller body 1 can smoothly transport the fabric surface; on the other hand, the lifting mechanism 5 can drive the non-fixed edge end 42 to adjust up and down, thereby balancing the fabric tension on the roller surface 11 of the roller body 1; therefore, through the technical solution of this utility model, the tension balance of the fabric surface can be well achieved, ensuring that the fabric is evenly and flat, thereby effectively overcoming the problem of uneven dyeing caused by uneven winding of the fabric roll, unevenness, and insufficient carbon dioxide flow rate and concentration at both ends due to the fabric roll fraying effect, and ensuring the waterless dyeing effect.

Please refer to the detailed description of Embodiment 1 for details, which will not be repeated here. Existing fabric winding machines have three feed rollers before the yarn is wound onto the bobbin. In this utility model, the feed roller located in the middle position of the three feed rollers is replaced with the aforementioned balance roller 100 to better achieve tension balance on the fabric surface and ensure uniform and flat fabric loading.
