[0002] Warp knitted fabrics are suitable for applications that require a smooth appearance and good breathability, such as clothing, household items, and automotive interiors, due to their good stability and stiffness. In addition, they are also suitable for products that require a stable structure, due to their resistance to unraveling and curling.

[0003] In the process of warp knitted fabric production, the completed warp knitted fabric needs to be rolled up in time to facilitate subsequent storage. In order to ensure the tightness between the layers of warp knitted fabric during winding, a certain winding tensioning force needs to be given to the warp knitted fabric. However, although the existence of the winding tensioning force can ensure the tightness of the warp knitted fabric during winding, the warp knitted fabric will be wrinkled along its length when it is pulled along its length.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0020] In an embodiment of the present invention, a warp knitted fabric constant tension winding device comprises: a base 1, an elastic tensioning assembly, a transmission assembly and a flattening assembly, so that on the one hand, when the warp knitted fabric is rolled up by the winding roller, a certain degree of flattening effect can be achieved on the warp knitted fabric, and on the other hand, when the number of layers of the warp knitted fabric on the winding roller increases and the thickness increases, the abutment roller can change its position in real time, and adjust the height of the second column spring through the connecting structure to ensure that as the winding thickness increases and the winding speed increases, the second column spring can maintain the original compression amount, and then the second column spring can provide a constant tensioning force for the winding of the warp knitted fabric through the pressure roller, thereby ensuring the winding effect of the warp knitted fabric, as follows: Please refer to the following for details: Figure 1 to Figure 11 A winding roller 4 is detachably mounted on the base 1; the elastic tensioning assembly is arranged on the base 1, and the warp knitted fabric passes through the elastic tensioning assembly and is wound on the winding roller 4, the elastic tensioning assembly includes a bracket 3 arranged on the base 1, two groups of first horizontal rollers 25 are arranged on the bracket 3, and two groups of side frames 20 are installed on the side of the bracket 3, a connecting member 23 is slidably mounted on the side frame 20, and a lower pressure roller 24 parallel to the first horizontal roller 25 is rotatably mounted on the connecting member 23; the elastic tensioning assembly also includes a second columnar spring 22 connected to the connecting member 23 and the connecting structure, and the second columnar spring 22 is used to provide tensioning force to the warp knitted fabric.

[0021] When in use, the weaving machine weaves the warp knitted fabric, and the woven warp knitted fabric is passed around the upper part of the first group of first horizontal rollers 25, and passed around the lower part of the lower pressure roller 24, and then passed around the upper part of the other group of first horizontal rollers 25, and is wound on the winding roller 4 by pulling, and then the driving motor (not shown in the figure) connected to the rotating shaft of the winding roller 4 is controlled to work, so that the winding roller 4 can wind up the warp knitted fabric. In this process, the warp knitted fabric should be controlled to have a predetermined tension, that is, the warp knitted fabric has a force to drive the lower pressure roller 24 to move upward, and the second columnar spring 22 is compressed to a certain extent. The elastic force provided by the second columnar spring 22 ensures the tension of the lower pressure roller 24 on the warp knitted fabric, so that the warp knitted fabric can be wound on the winding roller 4 with a predetermined tension, thereby improving the compactness between the layers of the warp knitted fabric wound on the winding roller 4, and avoiding the warp knitted fabric from wrinkling due to looseness during winding.

[0022] See also Figure 1~Figure 2 , Figure 7The flattening component is arranged on the base 1, and the flattening component can pull the two sides of the warp knitted fabric during the process of the warp knitted fabric being rolled up. The flattening component includes a retardation groove 301 arranged on the bracket 3, and a pressure rod 27 is slidably installed in the retardation groove 301, and two groups of inclined rollers 28 are symmetrically rotatably installed on the pressure rod 27; a vertical shaft 30 that is slidably connected to the end of the pressure rod 27 is also installed in the retardation groove 301, and a third columnar spring 29 is sleeved on the vertical shaft 30, one end of the third columnar spring 29 is connected to the pressure rod 27, and the other end is connected to the inner wall of the retardation groove 301; the flattening component also includes a second horizontal roller 26 that is rotatably installed on the bracket 3 and adapted to the inclined roller 28.

[0023] During the process of winding the warp knitted fabric, the warp knitted fabric is in a state of sliding cooperation with the inclined roller 28. At this time, as the winding roller 4 pulls the warp knitted fabric, the warp knitted fabric can slide relative to the inclined roller 28. Specifically, one side of the warp knitted fabric is supported by the second horizontal roller 26, and the other side is pressed by the inclined roller 28, so that when the warp knitted fabric moves, the inclined roller 28 can follow the rotation and provide a force to pull the warp knitted fabric toward the side of the warp knitted fabric, thereby achieving the effect of pulling both sides of the warp knitted fabric, making the warp knitted fabric smoother when wound on the winding roller 4, further preventing the formation of wrinkles and improving the winding process.

[0024] It should be noted that the inclined direction of the inclined roller 28 is: the side of its rotating shaft facing the side of the warp knitted fabric is at the rear side of the direction in which the warp knitted fabric is rolled up compared to the other side, so that when the warp knitted fabric slides relative to the inclined roller 28, a friction separation along the length direction of the warp knitted fabric and a friction component force along the width direction of the warp knitted fabric can be generated. Under the action of the friction component force along the width direction of the warp knitted fabric, the side of the friction component force along the width direction of the warp knitted fabric can be pulled, which has the effect of making the warp knitted fabric flat.

[0025] See also Figure 1 , Figure 6The transmission assembly is connected to the elastic tensioning assembly and rolls with the warp knitted fabric wound on the winding roller 4. The transmission assembly includes a contact structure and a connecting structure. The contact structure can drive the connecting structure to move according to the thickness of the warp knitted fabric wound on the winding roller 4, so as to switch the position of the elastic tensioning assembly; the contact structure includes two groups of support frames 2 arranged on the base 1, and the support frame 2 is provided with a first slide groove 5 along its length direction, and a follower rod 6 is slidably installed in the first slide groove 5, and an abutment roller 7 is rotatably installed on the follower rod 6, and the abutment roller 7 is rollably installed with the warp knitted fabric wound on the winding roller 4; the abutment structure also includes a first columnar spring 8 arranged in the first slide groove 5, one end of the first columnar spring 8 is connected to the follower rod 6, and the other end is connected to the inner wall of the first slide groove 5.

[0026] Furthermore, in the initial state, the first column spring 8 is in a stretched state. At this time, the first column spring 8 has a force to pull the follower rod 6 to move upward, so that the contact roller 7 can fit the warp knitted fabric wound on the winding roller 4. On the one hand, when the winding roller 4 winds up the warp knitted fabric, it can achieve a certain degree of flattening effect on the warp knitted fabric. On the other hand, when the number of layers of the warp knitted fabric on the winding roller 4 increases and the thickness increases, the contact roller 7 can change its position in real time and adjust the height of the second column spring 22 through the connecting structure to ensure that as the winding thickness increases and the winding speed increases, the second column spring 22 can maintain the original compression amount, so that the second column spring 22 can provide a constant tensioning force for the winding of the warp knitted fabric through the pressure roller 24, thereby ensuring the winding effect of the warp knitted fabric.

[0027] See also Figure 5 , Figure 9~Figure 10 The connection structure includes: a telescopic plate, a side plate 13 and a driving kit.

[0028] The telescopic plate is connected to the follower rod 6, and an engaging portion is provided at one end of the telescopic plate. The telescopic plate includes a follower sleeve plate 9 fixedly connected to the follower rod 6, the interior of the follower sleeve plate 9 is a hollow structure, and a telescopic rod 10 is slidably installed in the follower sleeve plate 9, and a rack plate 12 is provided at one end of the telescopic rod 10. The rack plate 12 is inclined and forms the engaging portion; when the follower rod 6 moves downward, the rack plate 12 can drive the driving kit to move; the side plate 13 is fixedly installed on the base 1, and the side plate 13 is connected to the telescopic plate through a grooved shaft structure, and the grooved shaft structure includes an engaging shaft 11 rotatably installed on the telescopic rod 10 and an inclined groove 14 arranged on the side plate 13, the engaging shaft 11 can roll in the inclined groove 14, and the length direction of the inclined groove 14 is parallel to the length direction of the rack plate 12.

[0029] In the initial state, the follower rod 6 is at the highest point of its stroke. At this time, the engaging shaft 11 is at the upper end of the inclined groove 14, and the gear 15 is in meshing with the rack plate 12. As the winding roller 4 rotates and the warp knitted fabric is wound, the thickness of the warp knitted fabric wound on the winding roller 4 will increase. At this time, the abutment roller 7 will move downward and drive the follower rod 6 to move downward. During this process, the follower rod 6 drives the telescopic rod 10 to move downward through the follower sleeve 9, and enables the engaging shaft 11 to move along the length direction of the inclined groove 14. At this time, the rack plate 12 can move along its length direction, while maintaining meshing with the gear 15, causing the gear 15 to rotate, thereby driving the drive kit to operate, thereby increasing the position of the second column spring 22, so that the second column spring 22 maintains a constant degree of compression, and achieves the effect of keeping the warp knitted fabric winding tension constant.

[0030] It should be noted that the drive kit mainly adjusts the position of the second cylindrical spring 22 in the form of threaded transmission, and if the rack plate 12 is directly connected to the follower rod 6, considering the effective descending amount of the follower rod 6, the gear 15 is required to drive the drive kit to move through a relatively large belt transmission structure. At this time, the torque required for the rotation of the gear 15 is very large, which increases the resistance to the descent of the abutment roller 7, which can easily cause the abutment roller 7 to further squeeze the warp knitted fabric wound on the winding roller 4, causing the warp knitted fabric to deform. Through the above-mentioned arrangement, the downward movement of the follower rod 6 is converted into the lateral movement of the telescopic rod 10, thereby effectively reducing the resistance to the downward movement of the abutment roller 7 and preventing the warp knitted fabric from being compressed and deformed. At the same time, the gear 15 can generate a sufficient number of rotations to drive the drive kit to move.

[0031] See also Figure 3 , Figure 7 , Figure 8 , Fig.11, the driving kit is connected to the side plate 13, and the driving kit cooperates with the meshing portion, so that when the follower rod 6 moves downward, the end of the second cylindrical spring 22 away from the connecting member 23 can be driven to move upward; the driving kit includes a gear 15 rotatably mounted on the side plate 13, the gear 15 is meshed with the rack plate 12, and the gear 15 is connected to a bevel gear set 16 arranged on the side plate 13; the driving kit also includes a threaded adjustment module rotatably mounted on the side frame 20, two groups of the threaded adjustment modules are connected by a second belt 19, and one group of the threaded adjustment modules is connected to the bevel gear set 16 by a first belt 17, the threaded adjustment module is rotatably mounted on the side frame 20, and a threaded sleeve 21 threadedly connected thereto is provided on the screw 18, and the threaded sleeve 21 is slidably connected to the side frame 20, the second cylindrical spring 22 is sleeved on the screw 18, and the end of the second cylindrical spring 22 away from the connecting member 23 is connected to the threaded sleeve 21.

[0032] When the gear 15 rotates, the screw rod 18 can be driven to rotate through the bevel gear set 16 and the second belt 19, so that the threaded sleeve 21 that is threadedly matched with the screw rod 18 and slidingly connected to the side frame 20 can move along the length direction of the screw rod 18. Specifically, when the follower rod 6 moves downward, the threaded sleeve 21 can move upward, thereby causing the second columnar spring 22 to move upward, so that the second columnar spring 22 can maintain a constant compression amount, and then the lower pressure roller 24 acts on the warp knitted fabric to make the tensioning force of the warp knitted fabric constant, thereby improving the winding effect of the warp knitted fabric.

[0033] As an embodiment of the present invention, a warp knitting machine is also proposed, comprising the warp knitted fabric constant tension force winding device.
