Description

Technical Field

[0001] This utility model relates to the field of double needle bed warp knitting machine technology, and in particular to a comb drive structure for a double needle bed warp knitting machine. Background Technology

[0002] Double-needle-bed warp knitting machines are typically used to produce spaced fabrics, which are warp-knitted fabrics that use a middle yarn to connect the front and back surface fabrics at a certain interval. The interval distance is determined by the spacing between the front and back needle beds of the machine. The spacer comb in its guide bar mechanism guides the spacer yarns to swing between the front and back needle beds to complete the knitting process.

[0003] In traditional double-needle bed warp knitting machines, to improve the rigidity and longitudinal straightness of the guide bar, the upper and lower swing arms are fixed to two swing axes using a half-type structure. Therefore, it is impossible to adjust the stroke of the upper swing arm and the guide bar according to the processing requirements. Furthermore, the upper swing arm and the guide bar are fused and fixed together. In the longitudinal layout, this will increase the number of upper connecting rods and lower swing arms, resulting in a larger longitudinal space occupation rate, which is not conducive to the layout of other knitting element transmission mechanisms.

The upper swing arm is fixedly mounted on the upper swing shaft, and the comb fixing assembly is mounted on the upper swing shaft and located on one side of the upper swing arm. The wall panels are provided in a plurality of evenly distributed on the bed frame. The lower swing shaft is provided through the plurality of wall panels and is rotatably connected to each wall panel. The lower swing arm is sleeved on the lower swing shaft, and a bearing is provided between the lower swing arm and the lower swing shaft. The upper connecting rod is provided between the upper swing arm and the lower swing arm, and one end of the upper connecting rod is rotatably connected to the upper swing arm and the other end is movably engaged with the lower swing arm. The bed frame is provided with a drive mechanism, and the lower connecting rod is installed on the drive mechanism inside the bed frame, and one end is also movably engaged with the lower swing arm.

[0006] Furthermore, the comb fixing assembly includes a secondary arm, a retaining sleeve, and a guide seat. The secondary arm is mounted on the upper swing shaft, the retaining sleeve is mounted on the secondary arm, and the guide seat is mounted on the secondary arm.

[0007] Furthermore, the upper connecting rod includes a first support rod, a second support rod, and a snap-fit ​​component. The first support rod is mounted on the upper swing arm and is rotatably connected to the upper swing arm. The bottom end of the second support rod is provided with a spherical groove. The second support rod is located below the first support rod, and the top end of the second support rod is provided with a ball-head connector. The ball-head connector is snapped into the spherical groove and is adapted to the spherical groove. The snap-fit ​​component is located at the bottom end of the second support rod and is fixedly connected to the second support rod.

[0013] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0014] Firstly, in order to improve the rigidity and longitudinal straightness of the guide bar in the traditional double needle bed warp knitting machine guide bar drive structure, the upper and lower swing arms are fixed on two swing shafts respectively using a half-type structure. Therefore, it is impossible to adjust the stroke of the upper swing arm and the guide bar reciprocating according to the processing requirements. Furthermore, the upper swing arm and the guide bar are fused and fixed, which will increase the number of upper connecting rods and lower swing arms in the longitudinal layout, resulting in a larger longitudinal space occupation rate, which is not conducive to the layout of other knitting element drive mechanisms.

[0015] The comb fixing component and the upper swing arm in this utility model are designed separately, which makes it more flexible in the longitudinal layout and occupies less space. The upper connecting rod and the lower connecting rod can be connected to the lower swing arm respectively to adjust the swing stroke of the comb installed on the comb fixing component.

[0016] Secondly, after the lower connecting rod is angled, the retaining pin on one side of the top of the lower connecting rod can be inserted into one of the limiting slots corresponding to the second groove, so that the connection position between the lower connecting rod and the lower swing arm can be adjusted to make a certain swing amplitude fine adjustment of the upper swing arm in conjunction with the upper connecting rod.

[0017] When adjusting the connection position between the upper connecting rod and the lower swing arm, first rotate the fixing sleeve to completely disengage the threaded groove inside the fixing sleeve from the thread on the second support rod. Then pull the fixing sleeve upwards to move it away from the connection position between the first and second support rods. At this point, the second support rod can be directly moved, and the retaining pin on one side of the retaining piece can be pulled out of the corresponding retaining groove. The second support rod can then drive the ball joint connector at the top to rotate in the spherical retaining groove, ensuring that the first and second support rods remain connected. Next, adjust the corresponding position of the retaining piece and the first groove, while inserting the retaining pin on one side of the retaining piece into the corresponding retaining groove. Finally, pull the fixing sleeve downwards and rotate it to reconnect the threaded groove inside the fixing sleeve with the thread on the second support rod, thus completing the adjustment of the connection position between the upper connecting rod and the lower swing arm.

[0018] Thirdly, after the upper and lower connecting rods are adjusted to their respective connection positions with the lower swing arm, each cover plate can be installed in the corresponding first and second grooves. The retaining pins on the top side of the lower connecting rod and the retaining pins on the side of the retaining piece are respectively engaged in the limiting holes on the corresponding cover plates. Then, each cover plate is connected and fixed to the lower swing arm with fixing bolts. This allows the upper and lower connecting rods to be adjusted to their connection positions with the lower swing arm according to processing requirements. After that, the corresponding cover plates are installed to limit the first and second grooves to prevent the lower connecting rod and retaining piece from dislodging during operation.
