Description

Technical Field

[0001] The utility model relates to the field of water jet looms, in particular to a beating-up shaft supporting structure. Background Art

[0002] The water jet loom is a shuttleless loom that uses a jet of water to pull the weft yarn through the shed. The frictional traction of the water jet weft insertion on the weft yarn is greater than that of the air jet weft insertion, and the diffusion is small, which is suitable for the weft insertion of synthetic fibers, glass fibers and other filaments with smooth surfaces. At the same time, the water jet weft insertion can increase the conductivity of synthetic fibers and effectively overcome static electricity in weaving. In addition, the water jet weft insertion consumes less energy and has the lowest noise, and the beating shaft is an important component of the water jet loom.

[0003] For example, the patent with authorization announcement number CN219793268U discloses a beating mechanism for a water jet loom, which improves the convenience of disassembly and maintenance and improves maintenance efficiency; it includes a beating shaft and two groups of support seats, and the left and right ends of the beating shaft are respectively rotatably set on the two groups of support seats; it also includes a moving device, two groups of spline shafts, two groups of spline sleeves and two groups of sliders, the two groups of spline shafts are respectively concentrically installed on the left and right ends of the beating shaft, the two groups of spline sleeves are respectively rotatably installed on the two groups of support seats, the ends of the two groups of spline shafts are respectively slid into the interior of the two groups of spline sleeves, the bottom ends of the two groups of support seats are respectively connected to the top ends of the two groups of sliders, and the two groups of sliders are both installed on the moving device, and the moving device is used to drive the two groups of sliders to move toward each other.

[0004] The above patent drives the two sets of sliders to move away from each other through a moving device, so that the two sets of spline sleeves are slid and separated from the two sets of spline shafts, thereby improving the convenience of disassembly and maintenance of the weft shaft and improving the maintenance efficiency of the mechanism; however, in the above patent, bearings are required when the weft shaft is installed on the support seat, and the body of the water jet loom will be filled with a large amount of water. When the bearings are flooded with water, rust may occur. The above patent lacks waterproof measures for the bearings.

[0005] Therefore, it is necessary for us to improve such a structure to overcome the above-mentioned defects. Utility Model Content

Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. The components of the embodiment of the utility model generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiment of the utility model provided in the drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents the selected embodiment of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model.

[0026] The waterproof effect of ordinary bearings is average.

[0027] See also Figure 1-6 , a beating shaft support structure, including a shaft seat body;

[0028] The shaft seat body 1 is rotatably connected with a beating shaft 2 through a bearing. It is worth noting that since the main protection technical feature of the utility model is the structure supporting the beating shaft, that is, the installation structure of the beating shaft and the bearing seat, the schematic diagram of the beating shaft 2 in the figures of this specification is only the end structure of the beating shaft 2, not the structure of the entire beating shaft, only for the convenience of showing the simplified structure of the utility model;

[0029] The two ends of the shaft seat body 1 are provided with end covers 3, and the beating shaft 2 is provided with at least a first bearing 4 and a second bearing 5.

[0030] The inner ring of the first bearing 4 abuts against the shoulder of the beating-up shaft 2. Similarly, the left side of the inner ring of the second bearing 5 abuts against another shoulder of the beating-up shaft 2. Meanwhile, the right side of the second bearing 5 abuts against the left end of the shaft clamp 501, and the shaft clamp 501 is fixedly sleeved on the right end of the beating-up shaft 2.

[0031] At the same time, the right side of the outer ring of the first bearing 4 abuts against the retaining spring 401, and the left side of the outer ring of the second bearing 5 also abuts against another retaining spring 401. The two retaining springs 401 are both clamped in the shaft seat body 1.

[0032] An abutment ring 301 is also provided on the inner side of the end cover 3, and the left side of the outer ring of the first bearing 4 and the right side of the outer ring of the second bearing 5 are respectively abutted against the abutment ring 301 on the adjacent end cover 3;

[0033] In this solution, the first bearing 4 is a cylindrical roller bearing, and the second bearing 5 is a double-row angular contact ball bearing.

[0038] The right end of the waterproof housing 601 is also provided with a connecting flange 605, on which a through hole is opened, and the connecting flange 605 is fixedly connected to the end cover 3 and the shaft seat body 1 by screws, and the screws pass through the connecting flange 605 and the end cover 3 in sequence to be connected to the shaft seat body 1;

[0039] At least two waterproof rings 606 are arranged in the waterproof housing 601, and an annular mounting groove 609 for mounting the waterproof ring 606 is opened on the inner wall of the waterproof housing 601; the inner wall of the waterproof ring 606 abuts against the side wall of the beating shaft;

[0040] At the same time, the left end of the waterproof housing 601 is closed, which can effectively reduce the probability of water entering;

[0041] The utility model provides a plurality of waterproof rings 606 to achieve a better waterproof effect, and also provides a waterproof housing 601 with a longer axial length, which can better prevent water from entering the interior of the shaft seat body 1 through the waterproof housing 601;

[0042] When the utility model is used, the end of the beating-up shaft is first installed in the shaft seat body, and then the end of the shaft seat body is connected to the waterproof structure 6; when in use, the water flow on the working part of the beating-up shaft will be blocked by the waterproof ring 606.

[0043] Specifically, at least two groups of symmetrically arranged first sealing lips 607 and second sealing lips 608 are arranged on the inner side of the waterproof ring 606, wherein the first sealing lips 607 are located on the inner side of the second sealing lips 608, and the first sealing lips 607 abut against the side wall of the beating shaft;

[0045] like Figure 7 In this solution, in order to facilitate the installation of the waterproof ring 606, the waterproof housing 601 is divided into two mutually axially symmetrical semicircular tubular members 610, so the connecting flange 605 and the plug-in ring 602 are also divided into two mutually symmetrical ones;

[0046] At the same time, a connecting wing plate 611 is integrally formed on the outer side of the semicircular tubular member 610, and the connecting wing plate 611 on the semicircular tubular member 610 is fixedly connected by bolts;

[0047] At the same time, a sealant groove 612 is also provided on the semicircular tubular member 610 . When the two semicircular tubular members 610 are butt-jointed, sealant is injected into the sealant groove 612 to ensure the sealing between the side walls of the semicircular tubular members 610 .
