Description

Technical Field

[0001] This utility model relates to the field of water jet loom technology, and in particular to a frame for a water jet loom. Background Technology

[0002] When using a water-jet loom, a left center plate (i.e., warp feed wall plate) is added to the loom as a support for the conveyor rollers, warp beams, etc. A search reveals that Chinese patent CN 221588825 U discloses a frame for a water-jet loom, including a warp feed wall plate. The outer surface of the warp feed wall plate has a groove, and a lifting and adjusting mechanism is installed through the groove. A drive mechanism that cooperates with the lifting and adjusting mechanism is installed on the top of the warp feed wall plate. This frame, through the lifting and adjusting mechanism, allows for adjustment of the threaded sleeve to any position via threaded adjustment. The drive mechanism allows for quick adjustment of the threaded sleeve by simply turning a nut, which rotates two lead screws.

[0003] Although the above frame can freely adjust the position of the threaded sleeves, the center distance between the threaded sleeves is fixed, which cannot be adapted to warp beam seats with different center distances, resulting in low versatility. Furthermore, the position of the threaded sleeves needs to be adjusted manually, resulting in low position adjustment accuracy and efficiency, which affects the installation accuracy of the warp beam and ultimately affects the weaving quality of the water jet loom.

The motor drive mechanism is used to drive the support seat 2 to rise and fall along the guide rods 3. An installation groove 201 is provided on the right side wall of the support seat 2. Several sets of threaded sleeves 4 are fitted in the installation groove 201. Several sets of positioning grooves 202 are provided on the inner walls of both sides of the installation groove 201. A plug-in platform 401 that matches the positioning groove 202 is welded to the side wall of the threaded sleeve 4. Several sets of reinforcing ribs 403 are welded at the connection between the plug-in platform 401 and the threaded sleeve 4. A cover plate 5 is detachably installed on the right end of the installation groove 201 by bolts.

[0021] In this embodiment, the mounting groove 201 has a rectangular structure, and an oblong hole 203 is provided on the bottom wall of the mounting groove 201. The fixing bolt of the bearing seat passes through the oblong hole 203 and connects with the threaded sleeve, thereby fixing the bearing seat on the left side wall of the bearing seat 2. Several sets of positioning grooves 202 are symmetrically arranged with the middle of the mounting groove 201 as the center. The spacing between the positioning grooves 202 on the same side is 5mm. By installing the threaded sleeve 4 into the positioning grooves 202 at different positions, it can be used for bearing seats with different center distances within a certain range.

[0022] In this embodiment, a limiting platform 402 is welded to one end of the side wall of the threaded sleeve 4 near the waist-shaped hole 203. The limiting platform 402 has a T-shaped structure. The two end side walls of the limiting platform 402 are parallel and aligned with the two inner walls of the mounting groove 201. The bolt sleeve 4 is installed in the inner chamber of the mounting groove 201. The two ends of the limiting platform 402 are in close contact with the two inner walls of the mounting groove 201, which improves the stability of the threaded sleeve 4 installed on the bearing seat 2.

[0023] In this embodiment, the upper and lower end sidewalls of the bearing seat 2 are provided with connecting holes 204. The guide rod 3 is installed in the connecting holes 204 through bushings. The upper and lower end of the slide groove 101 are provided with grooves 102. The support seat 6 is fixedly installed in the grooves 102 by bolts.

With the cooperation of the lead screw 7 and the lead screw nut 8, the bearing seat 2 slides along the guide rod 3, thereby realizing the automatic adjustment of the height of the bearing seat 2.

[0024] In use, according to the center distance of the warp beam seat to be installed, the insertion platforms 401 on the side walls of the two sets of threaded sleeves 4 are inserted into the positioning grooves 202 with the same spacing. Then, the cover plate 5 is installed on the bearing seat 2. The cover plate 5 prevents the threaded sleeves 4 from detaching from the mounting grooves 201, thus completing the installation of the threaded sleeves 4. When it is necessary to adjust the height of the warp beam, the servo motor 9 drives the lead screw 7 to rotate. With the cooperation of the lead screw 7 and the lead screw nut 8, the bearing seat 2 moves along the guide rod 3 in the slide groove 101 to realize the automatic adjustment of the height of the bearing seat 2. This improves the accuracy and efficiency of the position adjustment of the threaded sleeves 4, thereby ensuring the installation accuracy of the warp beam and thus ensuring the weaving quality of the water jet loom. After the height of the bearing seat 2 is adjusted, the warp beam seat is placed on the left side wall of the bearing seat 2. The fixing bolts for fixing the warp beam seat are passed through the waist-shaped hole 203 and installed on the threaded sleeves 4 to complete the installation of the warp beam.
