Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of textile machinery, and particularly relates to an elastic roller mechanism for a warp knitting machine. Background Art
[0002] As one of the important production equipment in the field of textile machinery, the performance and stability of a warp knitting machine directly affect the quality and production efficiency of textiles. Among the numerous key components of a warp knitting machine, the roller mechanism plays a crucial role. Especially when dealing with elastic or high-tension yarns, the fitting degree and flexibility of the roller mechanism become technical difficulties and research focuses.
[0003] The roller mechanism of traditional warp knitting machines generally adopts a design mode in which the inner and outer rollers are closely fitted. Among them, the inner roller is fixedly installed, and the outer roller is responsible for providing the necessary driving force during the swinging and rising process of the machine to ensure that the yarn can pass smoothly. This design can better realize the guiding and control of the yarn during the rising stage. However, during the descending stage, due to the fixity of the inner roller and various uncertain factors in its processing process (such as processing accuracy, clamping error, tool wear, etc.), it is often difficult to ensure the perfect fit of the inner and outer rollers, thus causing problems such as yarn tension fluctuation, slipping, and even breaking, which seriously affect the production efficiency and product quality.
[0004] Therefore, in order to solve the above problems, it is necessary to design an elastic roller mechanism for a warp knitting machine. Content of the Utility Model
[0005] The purpose of the utility model is to provide an elastic roller mechanism for a warp knitting machine to solve the technical problem of unstable fitting degree of the roller mechanism during the descending process.
[0006] In order to solve the above technical problems, the utility model provides an elastic roller mechanism for a warp knitting machine, including:
[0007] A connecting rod frame, which includes: several placement positions;
[0008] A roller assembly arranged in the corresponding placement position, which includes: a roller frame, an outer roller connected to the roller frame, an elastic member connected to the roller frame, a bearing and a cam connected to the other end of the elastic member; wherein
[0009] The outer roller is adapted to rollingly contact the outer wall of the cam when the cam rotates and rises, and drive the roller frame to move upward; and
[0010] The elastic member is adapted to support the bearing to be in close contact with the inner wall of the cam, so as to follow and drive the roller frame and the outer roller to move downward when the cam rotates and descends.
[0011] Further, the roller assembly further includes: a support shaft connected to the roller frame; wherein
[0012] The elastic member is fixed on the support shaft; and
[0013] The support shaft is located inside the inner wall of the cam.
[0014] Furthermore, the roller assembly further includes: an output shaft provided on the outer roller; wherein
[0015] The output shaft is adapted to move up or down following the outer roller.
[0016] Furthermore, a rotating shaft is provided on the link frame; wherein
[0017] The rotating shaft is connected to the link frame by a bearing; and
[0018] The rotating shaft penetrates through each cam; and
[0019] The rotating shaft is adapted to drive each cam to rotate.
[0020] Furthermore, a fixed shaft is provided on the link frame; wherein
[0021] The fixed shaft penetrates through each roller frame; and
[0022] Each roller frame is adapted to rotate around the fixed shaft.
[0023] Furthermore, an opening kit is provided on the side surface of the cam; wherein
[0024] The opening kit is sleeved on the rotating shaft; and
[0025] The opening kit is adapted to be clamped on the rotating shaft when locked; and
[0026] The opening kit is adapted to rotate following the rotating shaft and drive the cam to rotate.
[0027] The beneficial effects of the present utility model are:
[0028] (1) The present utility model provides an installation position for the roller assembly through the link frame, and the roller assembly realizes the up and down movement of the outer roller when the cam rotates through the combination of the roller frame, the outer roller, the elastic member, the bearing and the cam, and maintains close contact with the inner wall of the cam through the elastic member, ensuring stability and fit during the descending process.
[0029] (2) When the rotating shaft rotates on the connecting rod frame in the present utility model, the opening kit drives the cams to rotate synchronously. When the cams rotate upward, they contact the outer rollers and push the rollers and the roller frame upward. When the cams rotate downward, the elastic members maintain close contact with the inner walls of the cams, driving the outer rollers and the roller frame to move downward accordingly. The fixed shaft ensures that the roller frame can rotate flexibly during the up-and-down movement and maintain close cooperation with the cams. The support shaft provides stable support for the elastic members, enhancing the stability and durability of the elastic members. Thus, through the ingenious structural design, the efficient, stable, and flexible movement of the roller mechanism is achieved, providing a reliable guarantee for the operation of the warp knitting machine.
