Abstract
Description
A protective device for a water jet loom Technical Field
[0001] This utility model mainly relates to the field of water jet loom technology, and specifically to a protective device for a water jet loom. Background Technology
[0002] Water jet looms are shuttleless looms that use jets of water to guide the weft yarn through the shed. Water jet weft insertion exerts a greater frictional pulling force on the weft yarn than air jet weft insertion, with less diffusion, making it suitable for weft insertion of smooth-surfaced synthetic fibers, glass fibers, and other filaments. It also increases the electrical conductivity of synthetic fibers, effectively overcoming static electricity during weaving. Furthermore, water jet weft insertion consumes less energy and produces the lowest noise levels.
[0003] During the operation of specific embodiments, the inventors discovered the following defects:
[0004] Chinese Patent Publication No. CN219886285U discloses a protective device for a water jet loom, which includes two arc-shaped slides and support legs fixedly connected to the bottom of the arc-shaped slides. The support legs of different heights are customized according to the ground height of the take-up roller of the water jet loom in the workshop.
[0005] In the aforementioned mechanism, the outriggers need to be customized, which makes the device unsuitable for water jet looms of different heights. Furthermore, since the dimensions of water jet looms vary, the dimensions of the take-up rollers also differ, making it impossible to adjust the range of the protective device based on the length of the take-up rollers.
[0006] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Summary of the Invention

[0032] Referring to Figures 1-4, a protective device for a water jet loom includes a main protective cover 1, a secondary protective cover 2, and a base 3. The main protective cover 1 and the secondary protective cover 2 are movably connected, and a limiting connection mechanism is provided between the main protective cover 1 and the secondary protective cover 2. The base 3 is located below the main protective cover 1, and a height adjustment mechanism is provided between the base 3 and the main protective cover 1. A support plate 4 is fixedly installed on the top of the height adjustment mechanism, and the main protective cover 1 is installed on the top of the support plate 4.
[0033] In this embodiment, the height adjustment mechanism includes a first motor 5 fixedly installed at one end of the top of the base 3, a screw 6 connected to the output end of the first motor 5, a slide rod 7 fixedly connected to the other end of the top of the base 3, and a lifting cylinder 8 provided on the outside of both the screw 6 and the slide rod 7, with the top end of the lifting cylinder 8 fixedly connected to the bottom wall of the support plate 4.
[0034] It should be noted that the starting of the first motor 5 drives the screw 6 to rotate, the lifting cylinder 8 is raised, and the support plate 4 drives the main protective cover 1 to be raised, so that it matches the height of the take-up roller.
[0035] In this embodiment, one lifting cylinder 8 has a thread inside that matches the outside of the screw 6, one lifting cylinder 8 is threadedly connected to the screw 6, and the other lifting cylinder 8 is slidably connected to the slide rod 7.
[0036] It should be noted that this ensures the stable raising and lowering of the protective device.
[0037] In this embodiment, a main connecting block 9 is fixedly connected to the middle of both ends of the bottom wall of the main protective cover 1, and a secondary connecting block 10 is fixedly connected to one end of the bottom wall of the secondary protective cover 2. A telescopic connecting rod 11 is connected between the main connecting block 9 and the secondary connecting block 10.
[0038] It should be noted that the secondary protective cover 2 can be rotated upward by extending the telescopic link 11 and downward by retracting the telescopic link 11, which can be adjusted according to the length of the take-up roller.
[0039] In this embodiment, horizontal arc-shaped grooves 201 are provided on both sides of the secondary protective cover 2. A receiving block 13 is slidably connected inside the horizontal arc-shaped groove 201 through a compression spring 12. A horizontal limiting rod 14 is fixedly connected to one end of the receiving block 13. Limiting blocks 15 are fixedly connected to both ends of both sides of the main protective cover 1. The horizontal limiting rod 14 passes horizontally through the interior of the limiting block 15. A vertical arc-shaped groove 101 is provided on the side wall of the main protective cover 1 near the horizontal limiting rod 14. A moving block 17 is slidably connected inside the vertical arc-shaped groove 101 through a tension spring 16. A vertical limiting rod 18 is fixedly connected to the outer end of the moving block 17. The vertical limiting rod 18 passes vertically through the interior of the horizontal limiting rod 14.
[0040] It should be noted that by moving the receiving block 13 inside the horizontal arc groove 201 to stretch and compress the spring 12, the horizontal limiting rod 14 passes horizontally through the interior of the limiting block 15. At this time, the vertical limiting rod 18 pushes the moving block 17 to move upward inside the vertical arc groove 101 to compress the stretching spring 16. When one end of the horizontal limiting rod 14 passes through the interior of the limiting block 15, the elastic recovery of the stretching spring 16 causes the moving block 17 to move downward inside the vertical arc groove 101, so that the vertical limiting rod 18 passes vertically through the interior of the horizontal limiting rod 14, thereby achieving the limiting and fixing of the secondary protective cover 2.
[0041] In this embodiment, a second motor 19 is fixedly installed at one end inside the support plate 4. The output end of the second motor 19 is connected to a rotating shaft 20. A fixing plate 21 is fixedly connected to the outside of the rotating shaft 20. The fixing plate 21 is connected to the bottom wall of the main protective cover 1.
[0042] It should be noted that by starting the second motor 19 to drive the rotating shaft 20 to rotate, the rotating shaft 20 drives the fixed plate 21 and the main protective cover 1 to rotate, thereby changing the position of the protection, which can be better applied to the protection of the take-up rollers of different water jet looms.
[0043] The working principle of this utility model is as follows: In use, the protective device is positioned below the take-up roller of a water-jet loom. The starting of the first motor 5 drives the screw 6 to rotate, raising the lifting cylinder 8 upwards. The support plate 4 then raises the main protective cover 1 upwards to match the height of the take-up roller. When the length of the main protective cover 1 is suitable for the length of the take-up roller, the secondary protective cover 2 is perpendicular to both ends of the main protective cover 1. When the take-up roller is long and the protection range needs to be increased, the telescopic connecting rod 11 rotates the secondary protective cover 2 upwards to make it flush with the main protective cover 1. The receiving block 13 moves within the horizontal arc-shaped groove 201 to stretch and compress the spring 12, causing the horizontal limiting rod 14 to pass laterally through the interior of the limiting block 15. At this time, the vertical limiting rod 18 pushes the moving block 17 to move upward inside the vertical arc groove 101 to compress the tension spring 16. When one end of the horizontal limiting rod 14 passes through the interior of the limiting block 15, the elastic recovery of the tension spring 16 causes the moving block 17 to move downward inside the vertical arc groove 101, so that the vertical limiting rod 18 passes vertically through the interior of the horizontal limiting rod 14, thereby limiting and fixing the secondary protective cover 2. When it is necessary to adjust the angle of protection appropriately, the second motor 19 can be started to drive the rotating shaft 20 to rotate. The rotating shaft 20 drives the fixed plate 21 and the main protective cover 1 to rotate, thereby changing the position of the protection, which can be better applied to the protection of the take-up rollers of different water jet looms.
[0044] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
