Abstract
Description
Technical Field
[0001] This application relates to the field of fabric winding technology for open-width circular knitting machines, and specifically to a fabric winding device for an open-width circular knitting machine. Background Technology
[0002] When the open-width circular knitting machine is working, the woven fabric is fed downwards and guided to the front of the roll-up roller by multiple sets of guide rollers, and then rolled up by the roll-up roller.
[0003] The guide roller groups are set up differently at different locations. In some guide roller groups, there is a large gap between the guide rollers, and the guide roller group only plays a guiding role. In other guide roller groups, the guide rollers are clamped together, and the fabric is clamped while being guided. Therefore, during the winding process, the fabric is subjected to uneven force in different parts. Some parts of the fabric are in a tense state, while other parts are in a loose state. The tension of the fabric is different in different parts, which can easily affect the flatness of the fabric when it is wound on the roll roller. In addition, the guiding direction of the guide roller group of the existing open-width circular knitting machine makes the movement of the fabric more jerky and unsmooth. Utility Model Content
[0004] Therefore, it is necessary to provide a fabric winding device for a circular knitting machine to solve the problems of inconsistent tension and uneven movement of fabric in different parts of the fabric during the winding process of the existing circular knitting machine.
[0005] To achieve the above objectives, the inventor provides a fabric winding device for a circular knitting machine, comprising:
[0006] The first guide roller group is located below the needle plate of the circular knitting machine. The first guide roller group includes two first guide rollers. The two first guide rollers are at the same height and are arranged in parallel and tangentially to clamp the fabric together.
[0007] The second guide roller group is located at a lower height than the first guide roller group. The second guide roller group includes an upper guide roller and a lower guide roller. The lower guide roller is located at a lower height than the upper guide roller. The upper and lower guide rollers are parallel and tangentially arranged to clamp the fabric together.
[0008] A fabric winding roller is used to wind up fabric that has passed through the first guide roller group and the second guide roller group in sequence.
[0009] In some embodiments, the second guide roller group is provided with several groups, and the several groups of second guide roller groups are arranged sequentially from top to bottom.
[0010] In some embodiments, the lower projection of the first guide roller group is adjacent to the second guide roller group, and the lower projection of the first guide roller group intersects the axial direction of the second guide roller group.
[0011] In some embodiments, it also includes:
[0012] The guide roller is positioned at a height between the height of the first guide roller group and the height of the second guide roller group, and the lower projections of the guide roller, the first guide roller group, and the second guide roller group form a triangle.
[0013] In some embodiments, the surface of the steering guide roller is smooth.
[0014] In some embodiments, it also includes:
[0015] A rotary frame is connected to the needle plate of the open-width circular knitting machine and can rotate with the needle plate; the first guide roller group, the second guide roller group, and the roll roller are located at the rotary frame.
[0016] In some embodiments, it also includes:
[0017] A power mechanism, together with the first guide roller group, the second guide roller group, and the roll-up roller, drives the first guide roller group, the second guide roller group, and the roll-up roller to rotate.
[0018] In some embodiments, the power mechanism includes a first power group, a second power group, and a fabric winding power group, which are used to drive the first guide roller group, the second guide roller group, and the fabric winding roller to rotate, respectively.
[0019] In some embodiments, the surfaces of the first guide roller, the upper guide roller, and the lower guide roller are provided with an anti-slip layer.
[0020] In some embodiments, the height of the fabric roll roller is not higher than the height of the lower guide roller.
[0021] Unlike existing technologies, the fabric winding device of the open-width circular knitting machine described in the above technical solution guides the fabric movement through the first guide roller group and the second guide roller group, and finally winds it up through the winding roller. The two first guide rollers of the first guide roller group are at the same height and are parallel and tangentially arranged, meaning they are in close contact with each other. While guiding the fabric movement, the two first guide rollers also clamp the fabric together, ensuring that the fabric between the needle plate and the first guide roller group is kept taut. The second guide roller group includes an upper guide roller and a lower guide roller. The fabric first passes over the upper guide roller, then around the upper and lower guide rollers, then around the lower guide roller, and finally winds up at the winding roller. The lower guide roller is positioned lower than the upper guide roller. The height of the fabric guide rollers allows the fabric to gradually and smoothly descend, making its movement more fluid. Furthermore, the upper and lower guide rollers are parallel and tangential, meaning they are in close contact with each other. While guiding the fabric's movement, the upper and lower guide rollers also clamp it together, ensuring that the fabric between the second guide roller group and the roll-up roller is taut, as is the fabric between the first and second guide roller groups. Therefore, the roll-up device of the circular knitting machine ensures even force distribution across the fabric, keeping all parts of the fabric taut. This double tension prevents slippage, guarantees the flatness of the fabric rolled onto the roll-up roller, and adjusts the guiding direction for smoother fabric movement.

[0053] When the open-width circular knitting machine is working, the woven fabric is fed downwards and guided to the front of the roll-up roller by multiple sets of guide rollers, and then rolled up by the roll-up roller.
[0054] The guide roller groups are set up differently at different locations. In some guide roller groups, there is a large gap between the guide rollers, and the guide roller group only plays a guiding role. In other guide roller groups, the guide rollers are clamped together, and the fabric is clamped while being guided. Therefore, during the winding process, the fabric is subjected to uneven force in different parts. Some parts of the fabric are in a tense state, while other parts are in a loose state. The tension of the fabric is different in different parts, which can easily affect the flatness of the fabric when it is wound on the roll roller. In addition, the guiding direction of the guide roller group of the existing open-width circular knitting machine makes the movement of the fabric more jerky and unsmooth.
[0055] Therefore, this application provides a fabric winding device for a circular knitting machine, used to wind up the fabric woven by the circular knitting machine. In particular, while guiding the fabric at various points, it can clamp the fabric, ensure uniform tension while moving the fabric, avoid yarn slippage, and make the fabric feeding smoother.
[0056] Please see Figure 1 In a specific embodiment, the fabric winding device of the circular knitting machine includes a first guide roller group 1, a second guide roller group 2, and a winding roller 3; the first guide roller group 1 is located below the needle plate 9 of the circular knitting machine, and the first guide roller group 1 includes two first guide rollers 100. Please refer to [link to relevant documentation]. Figure 2 The two first guide rollers 100 are at the same height, parallel and tangential, to clamp the fabric together; please refer to Figure 3 The second guide roller group 2 is at a lower height than the first guide roller group 1. The second guide roller group 2 includes an upper guide roller 200 and a lower guide roller 201. The lower guide roller 201 is at a lower height than the upper guide roller 200. The upper guide roller 200 and the lower guide roller 201 are parallel and tangentially arranged to clamp the fabric 8 together. The winding roller 3 is used to wind up the fabric 8 that has passed through the first guide roller group 1 and the second guide roller group 2 in sequence.
[0057] The fabric winding device of the open-width circular knitting machine guides the fabric 8 to move through the first guide roller group 1 and the second guide roller group 2, and finally winds it up through the winding roller 3.
[0058] In the first guide roller group 1, the two first guide rollers 100 are at the same height, parallel and tangential, meaning they are in close contact with each other. While guiding the fabric 8, the two first guide rollers 100 also clamp the fabric 8 together, ensuring that the fabric 8 between the needle plate 9 and the first guide roller group 1 is stretched and in a taut state. The second guide roller group 2 includes an upper guide roller 200 and a lower guide roller 201. The fabric 8 first passes over the upper guide roller 200, then around the upper guide roller 200 and the lower guide roller 201, then around the lower guide roller 201, and finally is wound up at the roll-up roller 3. The lower guide roller 201 is at a lower height than the upper guide roller 200, allowing the fabric 8 to gradually and smoothly move downwards, making the fabric 8 travel more smoothly. Additionally, the upper guide roller 200... The upper guide roller 200 and the lower guide roller 201 are arranged parallel and tangentially, that is, the upper guide roller 200 and the lower guide roller 201 are in close contact with each other. While guiding the fabric 8 to move, the upper guide roller 200 and the lower guide roller 201 will also clamp the fabric 8 together, so as to ensure that the fabric 8 between the second guide roller group 2 and the roll roller 3 can be stretched and in a tensioned state, and also to ensure that the fabric 8 between the first guide roller group 1 and the second guide roller group 2 can be stretched and in a tensioned state.
[0059] Therefore, by double-tensioning the fabric 8 through the first guide roller group 1 and the second guide roller group 2, the winding device of the open-width circular knitting machine can make the fabric 8 be subjected to uniform force, so that all positions of the fabric 8 are in a taut state, avoiding yarn slippage, ensuring the flatness of the fabric 8 wound on the winding roller 3, and adjusting the guiding direction to make the fabric 8 move more smoothly and feed more smoothly.
[0060] In some embodiments, the lower projection of the first guide roller group 1 is adjacent to the second guide roller group 2, and the lower projection of the first guide roller group 1 intersects the axial direction of the second guide roller group 2.
[0061] Please see Figure 4 In some embodiments, the lower projection of the first guide roller group 1 is adjacent to the second guide roller group 2, and the lower projection of the first guide roller group 1 is orthogonal to the axial direction of the second guide roller group 2.
[0062] In some embodiments, a guiding roller 4 is further included. The height of the guiding roller 4 is between the height of the first guiding roller group 1 and the height of the second guiding roller group 2, and the lower projections of the guiding roller 4, the first guiding roller group 1, and the second guiding roller group 2 form a triangle. By changing the moving direction of the fabric 8 through the guiding roller 4, the moving direction of the fabric 8 is changed from vertical to horizontal and towards the second guiding roller group 2, so that the fabric 8 guided by the first guiding roller group 1 can move towards the second guiding roller group 2, and the second guiding roller group 2 can guide and clamp the fabric 8.
[0063] The steering guide roller 4 is used to change the direction of movement of the fabric 8. It can move the fabric 8 without driving it. It can cooperate with the first guide roller group 1 and the second guide roller group 2 to ensure the smooth movement of the fabric 8. Therefore, in some embodiments, the surface of the steering guide roller 4 is smooth.
[0064] In some embodiments, the guide roller 4 is a smooth stainless steel rod.
[0065] The first guide roller group 1 and the second guide roller group 2 need to drive the fabric 8 forward by their own rotation. In order to avoid slippage, in some embodiments, the surfaces of the first guide roller 100, the upper guide roller 200 and the lower guide roller 201 are provided with an anti-slip layer 101. The anti-slip layer 101 can prevent the fabric 8 from slipping relative to the first guide roller 100, the upper guide roller 200 and the lower guide roller 201.
[0066] In some embodiments, the anti-slip layer 101 can be a silicone sleeve, a rubber sleeve, or anti-slip protrusions on the surfaces of the first guide roller 100, the upper guide roller 200, and the lower guide roller 201. By providing the anti-slip sleeve, the fabric 8 can be prevented from slipping, ensuring that the fabric 8 can move forward at its inherent speed without stagnation, and ensuring that the fabric 8 is subjected to uniform force at all points.
[0067] In some embodiments, a rotary frame 5 is also included, which is connected to the needle plate 9 of the open-width circular knitting machine and can rotate with the needle plate 9; the first guide roller group 1, the second guide roller group 2, and the roll roller 3 are disposed at the rotary frame 5.
[0068] In some embodiments, the bottom of the rotary frame 5 is provided with a rotary disk 500, which can rotate synchronously with the needle plate 9 so that the entire fabric winding device of the open-width circular knitting machine can rotate with the operation of the needle plate 9.
[0069] In some embodiments, the first guide roller group 1 is mounted on the rotary frame 5 via a first base, and two first guide rollers 100 are mounted on the first base via a first mounting shaft, and the two first guide rollers 100 are rotatable via the first mounting shaft; similarly, the second guide roller group 2 is mounted on the rotary frame 5 via a second base, and the upper guide roller 200 and lower guide roller 201 are respectively mounted on the second base via a second mounting shaft, and the upper guide roller 200 and lower guide roller 201 are rotatable via the second mounting shaft; similarly, the fabric winding shaft is mounted on the rotary frame 5 via a third base, and the fabric winding shaft is mounted on the third base via a third mounting shaft, and the fabric winding shaft is rotatable via the third mounting base.
[0070] In some embodiments, the steering guide roller 4 is also located at the rotary frame 5, and the steering guide roller 4 is located at the rotary frame 5 via a fourth base, and the steering guide roller 4 is located at the fourth base via a mounting shaft.
[0071] In some embodiments, a power mechanism is also included, which, together with the first guide roller group 1, the second guide roller group 2, and the winding roller 3, drives the first guide roller group 1, the second guide roller group 2, and the winding roller 3 to rotate, thereby causing the first guide roller group 1 and the second guide roller group 2 to drive the fabric 8 forward, and causing the winding roller 3 to wind up the fabric 8.
[0072] In some embodiments, the power mechanism includes a first power group 6, a second power group 7, and a fabric winding power group, which are used to drive the first guide roller group 1, the second guide roller group 2, and the fabric winding roller 3 to rotate, respectively.
[0073] In some embodiments, the first power unit 6 is driven to the first mounting shaft to drive the first guide roller 100 to rotate and drive the fabric 8 forward; the second power unit 7 is driven to the second mounting shaft to drive the upper guide roller 200 and the lower guide roller 201 to rotate and drive the fabric 8 forward; the fabric winding power unit is driven to the third mounting shaft to drive the fabric winding roller 3 to rotate and wind up the fabric 8.
[0074] In some embodiments, the height of the roll roller 3 is not higher than the height of the lower guide roller 201. The path of the fabric 8 from the first guide roller group 1 to the second guide roller group 2, and then from the second guide roller group 2 to the roll roller 3, is all gently downward, making the fabric 8 travel more smoothly.
[0075] In some embodiments, the second guide roller group 2 is provided with several groups, such as Figure 5The diagram shows two sets of several sets of second guide roller groups 2 arranged sequentially from top to bottom. The upper guide roller 200 and lower guide roller 201 of each set of second guide roller groups 2 are tangentially arranged. Each set of second guide roller groups 2 can guide and convey the fabric 8 while clamping the fabric 8. The fabric 8 between adjacent sets of second guide roller groups 2 can be in a taut state, thereby making the entire open-width circular knitting machine's winding device have multiple tensions on the fabric 8. This ensures that the fabric 8 is subjected to uniform force and that all positions of the fabric 8 are in a taut state, preventing yarn slippage and ensuring the flatness of the fabric 8 wound on the winding roller 3.
[0076] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
