Description

Technical Field

[0001] This invention relates to the field of warp knitting machines, and more specifically to a comb cradle drive device. Background Technology

[0002] In the field of textile machinery, the guide bar cradle is a key component of high-speed warp knitting machines. Its function is to guide the yarn to the knitting area through reciprocating oscillation to achieve the interlacing of warp and weft yarns. Traditional guide bar cradles usually adopt a fixed structure, and the cradle is driven to oscillate periodically around the top axis through an eccentric wheel or cam mechanism.

[0003] However, in existing combing cradle devices, there are usually multiple cradles on the top shaft. When one of the cradles malfunctions and needs repair, the entire shaft and all cradles need to be removed, which is time-consuming and seriously affects the efficiency of equipment maintenance. Moreover, the mass distribution of the swing arm part of the existing cradle is fixed, and the moment of inertia cannot be finely adjusted according to changes in yarn denier, machine speed or pattern process. When the machine speed increases or the structure changes, problems such as swing lag and increased vibration are likely to occur, affecting the fabric quality. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned technical problems and provide a comb shank cradle drive device.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: a comb frame cradle drive device, comprising a cradle body, a top shaft, a quick-release mechanism, a counterweight, an adjustment mechanism, a connecting rod, and a power source. The cradle body includes a cradle section and a swing arm section. One end of the swing arm section is detachably connected to the cradle section. A mounting hole is provided between the swing arm section and the cradle section. The top shaft is disposed in the mounting hole. The quick-release mechanism is disposed between the swing arm section and the cradle section for quickly removing the cradle body from the top shaft. The counterweight is disposed on the swing arm section. The adjustment mechanism is disposed between the counterweight and the swing arm section for adjusting the position of the counterweight to change the moment of inertia of the swing arm section. One end of the connecting rod is rotatably disposed at one end of the swing arm section. The power source is connected to the other end of the connecting rod for driving the connecting rod to drive the cradle body to perform reciprocating swing motion.

[0006] Furthermore, a bearing is provided between the top axis and the mounting hole.

[0007] Furthermore, the quick-release mechanism includes a screw, a U-shaped groove, and a locking nut. The screw is rotatably mounted on the rocker arm, the U-shaped groove is mounted on the swing arm, and the locking nut is connected to the screw. After the screw enters the U-shaped groove, the locking nut is tightened to the screw to fix the swing arm to the rocker arm.

[0008] Furthermore, the quick-release mechanism has two sets, which are symmetrically arranged on both sides of the cradle.

[0009] Furthermore, a blocking block is provided at the inlet position of the U-shaped groove.

[0010] Furthermore, the height of the blocking block is 2mm.

[0011] Furthermore, the diameter of the screw is 1 mm smaller than the width of the U-shaped groove.

[0012] Furthermore, the adjustment mechanism includes an elongated groove, a through hole, an adjusting bolt, and an adjusting nut. The elongated groove is disposed on the swing arm, the through hole is disposed on the counterweight, the adjusting bolt passes through the through hole and the elongated groove, and the adjusting bolt is screwed into the adjusting nut.

[0013] Furthermore, the swing arm is provided with a rotating hole, and a pivot is provided in the rotating hole. The connecting rod is rotatably connected to the swing arm through the pivot.

[0014] Furthermore, the rotating hole has multiple holes, wherein the connecting rod is connected to different rotating holes to change the swing amplitude of the rocker body.

[0015] As can be seen from the above description of the present invention, compared with the prior art, the comb cradle drive device provided by the present invention has the following advantages: the quick-release mechanism allows for the removal of the faulty cradle body without disassembling the entire shaft, shortening maintenance time and improving maintenance efficiency; the adjustment mechanism can change the mass distribution of the swing arm of the cradle body by adjusting the position of the counterweight, thereby adjusting the moment of inertia of the swing arm so that the device can adapt to different yarn deniers, machine speeds and pattern processes, effectively avoiding swing lag and vibration problems, and improving fabric quality.

The base is removed from the top axis 2 to facilitate maintenance of the malfunctioning rocker body 1. The counterweight 4 is disposed on the swing arm 12. The adjustment mechanism 5 is disposed between the counterweight 4 and the swing arm 12 to adjust the position of the counterweight 4 to change the moment of inertia of the swing arm 12. One end of the connecting rod 6 is rotatably disposed at one end of the swing arm 12. The power source 7 is connected to the other end of the connecting rod 6 to drive the connecting rod 6 to drive the rocker body 1 to perform reciprocating swing motion.

[0022] A bearing is provided between the top shaft 2 and the mounting hole 8, and the bearing is used to reduce the friction between the hole wall of the mounting hole 8 and the top shaft 2.

[0023] The quick-release mechanism 3 has two sets, symmetrically arranged on both sides of the rocker arm portion 11 to ensure balanced force distribution. Specifically, the quick-release mechanism 3 includes a screw 31, a U-shaped groove 32, and a locking nut 33.
