Description

Technical Field

[0001] The utility model relates to the technical field of water jet looms, in particular to a shock absorbing device for a water jet loom. Background Art

[0002] A water jet loom is a shuttleless loom that uses a jet of water to pull the weft yarn through the shed. It uses clean water as a medium to guide the weft yarn, and generates friction traction on the weft yarn by jetting water. The traction force is greater than that of jet weft insertion and has less diffusion. It is suitable for the weft insertion of filaments such as synthetic fibers and glass fibers with smooth surfaces. Water jet looms are widely used in the weaving field. When the water jet loom is working, it will produce certain vibrations and noise. At the same time, long-term use will damage the water jet loom. In the prior art, shock absorption is performed by a shock absorbing device.

[0003] After searching, Chinese patent announcement number: CN209537729U discloses a shock absorbing device located at the bottom of a water jet loom frame, including a bottom plate, four bases are symmetrically fixedly installed on the top of the bottom plate, and the four bases are distributed in a rectangular shape. A columnar block is fixedly installed on the top of the base, a cavity is opened on the columnar block, and a baffle is slidably installed in the cavity. A first spring is fixedly installed at the bottom of the baffle, and the bottom end of the first spring is fixedly connected to the bottom inner wall of the cavity. Two sliding grooves are symmetrically opened on both sides of the cavity, and two sliders are symmetrically fixedly installed on the baffle. The sliders are slidably connected to the inner walls of the corresponding sliding grooves. A sliding hole is opened on the top inner wall of the cavity, and a sliding rod is slidably installed in the sliding hole.

[0004] Although the above technical solution can perform multi-level shock absorption on the water jet loom, its shock absorption direction is in the vertical direction. However, when the water jet loom is working, there is not only vertical vibration, but also horizontal vibration. The above technical solution has poor shock absorption measures in the horizontal direction, resulting in poor shock absorption effect of the water jet loom, which easily affects the working stability of the water jet loom.

The vibration of the water jet loom in the vertical direction is balanced by the multiple groups of shock absorbers 6 and the vertical shock absorbing components 7, and the vibration of the water jet loom in the horizontal direction is balanced by the horizontal shock absorbing components 11, which has a better buffering and shock absorbing effect and improves the working stability of the water jet loom.

[0030] In this embodiment, if Figure 3 and Figure 4 As shown, the vertical shock absorbing assembly 7 includes a moving column 701 and a sliding sleeve 702. The top of the moving column 701 is embedded and installed on the mounting plate 5, and the bottom of the sliding sleeve 702 is embedded and installed on the moving seat 4. The bottom end of the moving column 701 is movably inserted into the sliding sleeve 702 and fixedly connected with a first magnet 703. The bottom end of the sliding sleeve 702 is fixedly connected with a second magnet 704. The first magnet 703 and the second magnet 704 have the same magnetic poles and repel each other. When the water jet loom is working, the vibration generated causes the mounting plate 5 to move downward, squeezing the shock absorber 6. The shock absorber 6 can buffer most of the vertical vibrations and move the moving column 701 into the sliding sleeve 702 at the same time. Through the mutual repulsion between the first magnet 703 and the second magnet 704, part of the vibration can be buffered, and the mounting plate 5 can be quickly reset to ensure the stability of the water jet loom body 1.

[0031] In this embodiment, if Figure 2As shown, guide rods 8 are fixedly connected to the bottom of the mounting plate 5 and around the protrusions, and a guide sleeve 9 is embedded and installed on the movable seat 4 corresponding to the guide rod 8. The bottom end of the guide rod 8 is movably inserted in the guide sleeve 9. The guide rod 8 and the guide sleeve 9 are provided to play a role of limiting and guiding the mounting plate 5, thereby improving the stability of the mounting plate 5 generated by vibration during operation.

[0032] In this embodiment, if Figure 2 and Figure 5 As shown, the horizontal shock absorbing assembly 11 includes a sleeve 1101 fixedly connected to the bottom end of the base 3, a moving block 1102 is arranged inside the sleeve 1101, a support column 1103 is fixedly connected to the top of the moving block 1102, a top plate 1104 is fixedly connected to the top of the support column 1103, and the top plate 1104 is fixedly installed at the bottom of the moving seat 4. A plurality of shock absorbing springs 1107 are arranged at equal intervals along the circumferential direction between the outer wall of the moving block 1102 and the inner wall of the sleeve 1101, and the corresponding shock absorbing springs 1107 are arranged on the outer wall of the moving block 1102 and the inner wall of the sleeve 1101. A pair of limit blocks 1105 are fixedly connected at each end, and the end of the shock-absorbing spring 1107 is stuck in the limit block 1105. An energy-absorbing column 1106 is installed between the pair of limit blocks 1105 and inside the shock-absorbing spring 1107. When the water-jet loom body 1 generates horizontal vibration during operation, the support column 1103 drives the moving block 1102 to move inside the sleeve 1101, thereby squeezing the shock-absorbing spring 1107 and the energy-absorbing column 1106 to buffer horizontal vibrations, and can buffer multi-directional horizontal vibrations, greatly improving the shock-absorbing effect.

[0033] In this embodiment, if Figure 6 As shown, a plurality of second balls 1108 are rollingly embedded in the bottom end of the sleeve 1101 .

The size of the limit plate 10 is smaller than the size of the inner groove 301. The length and width of the limit plate 10 are both smaller than the length and width of the inner groove 301. When horizontal vibration occurs, the limit plate 10 moves horizontally in the inner groove 301 along with the movable seat 4. The friction of the limit plate 10 is reduced by the first balls 302, which can provide stable support for the movable seat 4 and improve the working stability of the water jet loom.

[0035] In this embodiment, if Figure 1 As shown, the bottoms of both sides of the water jet loom body 1 are fixedly connected with foot pads 12, and anchor screws 13 are inserted into the foot pads 12 to facilitate the fixed installation of the shock absorbing device in the use area.

[0036] Working principle: When in use, the water jet loom generates vibration, and the vibration causes the mounting plate 5 to move downward, squeezing the shock absorber 6. The shock absorber 6 can buffer most of the vertical vibrations and move the moving column 701 into the sliding sleeve 702. The first magnet 703 and the second magnet 704 repel each other, so that part of the vertical vibration can be buffered, and the mounting plate 5 can be quickly reset. The support column 1103 drives the moving block 1102 to move inside the sleeve 1101, thereby squeezing the shock absorbing spring 1107 and the energy absorbing column 1106 to buffer the horizontal vibration. The utility model can buffer and absorb vertical vibrations as well as horizontal vibrations, thereby improving the working stability of the water jet loom.

[0037] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
