Description

Technical Field

[0001] This utility model relates to the field of loom equipment technology, and specifically to a support device for ear yarn shafts. Background Technology

[0002] A loom is a textile machine used to weave or spin yarn or other thin materials into fabrics. Based on its power source, looms can be classified as water-powered looms, pneumatic looms, and electric looms. The main structure of a loom includes a yarn feeding device, a yarn guiding device, loom drums, a shuttle system, and the mechanisms that drive the various components of the loom. Among these, the shuttle system is a crucial part of the loom, consisting of the shuttle body, shuttle case, and shuttle beam, responsible for loading and conveying the weft yarn.

[0003] The earing bobbin, typically referring to a key component in the left and right earing devices on a water-jet loom, is a rope-like selvage mechanism. Its principle is that when the loom is running, the two earings twist together in a rope-like manner, tightly securing the weft yarn to ensure a tight and non-loose selvage. The earing bobbin is responsible for supporting and fixing the earings, ensuring their smooth and flexible operation. The earing bobbin usually consists of a bobbin body, bearings, and an earing fixing device. The bobbin body is the main part of the earing bobbin, used to support and fix the earings; the bearings reduce friction and wear on the bobbin body during operation; and the earing fixing device securely fixes the earings to the bobbin body.

[0004] Chinese Patent Application No. 202322996604.3 discloses a novel transmission structure for an ear wire shaft. The disclosed transmission structure includes an ear wire shaft, with a drive assembly and a support assembly respectively provided at both ends of the ear wire shaft. The drive assembly includes a bearing housing, a first bearing, a second bearing, and an ear wire drive shaft disposed within the bearing housing. The outer wall of the ear wire drive shaft is fastened to the inner rings of the first and second bearings. A first retaining ring capable of abutting against the first bearing is also provided outside the first bearing within the bearing housing. The outer ring of the second bearing abuts against the inner wall of the bearing housing, and a first oil seal is provided on one side of the second bearing within the bearing housing. The support assembly includes an ear wire shaft fixing seat, with a second retaining ring capable of abutting against the other side of the outer ring of the third bearing fixedly disposed within the ear wire shaft fixing seat. A second oil seal is provided on one side of the second retaining ring within the ear wire shaft fixing seat. Chinese Patent Application No. 202322991943.2 discloses a lower-end drive mechanism for a hemming box with left-right linkage. The disclosed drive mechanism includes a lower wall plate, an upper wall plate, and a support connecting the lower and upper wall plates. A drive shaft bearing housing is installed inside the lower wall plate. A lower-end lug drive shaft is connected to the drive shaft bearing housing via two first bearings. A short lug drive shaft passes through the central hole of the lower-end lug drive shaft. The short lug drive shaft passes through a lower hemming box with a sliding gear shaft. A long lug drive shaft is connected to the end of the short lug drive shaft via a lug shaft coupling. The long lug drive shaft passes through an upper hemming box with a hollow gear shaft. The long lug drive shaft is fixedly connected to the hollow gear shaft. A synchronous pulley is connected to the lower-end lug drive shaft via a key, and a synchronous belt is connected to the synchronous pulley.

[0005] In the aforementioned prior art, the lug shaft is supported by lug shaft fixing seats located at both ends. However, due to the long length and small diameter of the lug shaft, it is prone to vibration during high-speed rotation. The lug shaft fixing seats at both ends alone cannot stabilize the lug shaft, which can easily affect the stability of the entire loom and thus the quality of weaving. In addition, some existing lug shafts are equipped with separate support seats to support and stabilize the lug shaft. However, the current support seats cannot be adjusted and can only provide support and stability to the lug shaft in a fixed position. Furthermore, the existing support seats require the removal of the bearings, bearing seats, and other structures at the ends of the lug shaft to disassemble and reassemble the support seats, making the disassembly and assembly of the support seats too complicated and cumbersome, thus reducing work efficiency.

Detailed Implementation

[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] like Figures 1-5 As shown, a support device for an ear wire shaft includes a base 1 and an ear wire shaft 2 rotatably mounted on the base 1. The end of the base 1 is provided with a bearing seat 101 for connecting the ear wire shaft 2. The ear wire shaft 2 is provided with a support structure 3 for supporting the ear wire shaft 2. The support structure 3 is movably mounted on the base 1. The support structure 3 is detachably connected to the ear wire shaft 2.

[0030] The lug shaft 2 is arranged along the length of the base 1, and the bearing seats 101 are arranged at opposite ends of the base 1. The two ends of the lug shaft 2 are respectively arranged in the corresponding bearing seats 101, and the bearing seats 101 support the two ends of the lug shaft 2. Furthermore, a support structure 3 is provided on the lug shaft 2. Under the action of the support structure 3, the lug shaft 2 is guaranteed not to vibrate during rotation, thus improving the stability of the lug shaft 2. The support structure 3 can move along the length of the base 1, thereby realizing the adjustment of the support position of the support structure 3, thus improving the flexibility of the support structure 3 in supporting the lug shaft 2. In addition, by making the support structure 3 detachable, it is not necessary to remove the bearing seats 101 at the ends of the lug shaft 2 when disassembling and assembling the support structure 3, thus facilitating the disassembly and maintenance of the support structure 3 and improving the convenience of disassembly and assembly of the support structure 3.

[0031] The support structure 3 includes a slide 301 and a support seat 302 disposed on the slide 301. The slide 301 is slidably disposed on the base 1, and the support seat 302 is detachably connected to the slide 301. Furthermore, the slide 301 slides along the length direction of the base 1, thereby realizing the adjustment of the support position of the support structure 3. In addition, the support seat 302 is disposed on the side of the slide 301. By detachably disposing of the support seat 302 on the slide 301, it is convenient to assemble and disassemble the support seat 302 and the slide 301.

[0032] The slide block 301 has a sliding groove 3011 at its bottom that connects to the base 1. The end of the slide block 301 has a fixing hole 3012 for fastening the slide block 301. A bolt that abuts against the side of the base 1 is threaded into the fixing hole 3012. Furthermore, the sliding groove 3011 is located on the lower surface of the slide block 301 and is connected to the base 1. The sliding of the slide block 301 on the base 1 is achieved through the cooperation between the sliding groove 3011 and the base 1. In addition, the fixing hole 3012 is located on the end face of the slide block 301 and has an internal thread. The bolt is threaded into the fixing hole 3012. By rotating the bolt, the end of the bolt abuts against the side of the base 1, thereby fixing the slide block 301 in the corresponding position on the base 1. This ensures that the slide block 301 will not move, thereby improving the stability of the support structure 3 and preventing the support structure 3 from moving when the lug shaft 2 rotates.

[0033] The support base 302 is provided with a support groove 3021 that abuts against the lug shaft 2. The support groove 3021 is arranged along the axial direction of the lug shaft 2 and is located below the lug shaft 2. Furthermore, the support groove 3021 is arranged on the upper surface of the support base 302. The support groove 3021 is a semi-circular structure adapted to the lug shaft 2. The lug shaft 2 is located in the support groove 3021, and the support groove 3021 provides support for the lug shaft 2.

[0034] The support base 302 has a lubrication hole 3025 that is connected to the support groove 3021 and is used to provide lubricant to the support groove 3021. Furthermore, the lubrication hole 3025 is located at the bottom of the support base 302 and is connected to the support groove 3021. By adding lubricant to the support groove 3021 through the lubrication hole 3025, the friction between the support groove 3021 and the lug shaft 2 is reduced, thereby reducing the influence of the support groove 3021 on the rotation of the lug shaft 2. The lubricant can be a substance that can achieve lubrication, such as lubricating oil or lubricating grease.

[0035] The support base 302 is provided with a plurality of first mounting holes 3024 for connecting the slide 301. The slide 301 is provided with second mounting holes 3013 corresponding to the plurality of first mounting holes 3024. Furthermore, the first mounting holes 3024 are located at the bottom of the support base 302, and there are two first mounting holes 3024. The second mounting holes 3013 are located on the side of the slide 301. The first mounting holes 3024 and the second mounting holes 3013 are connected by bolts, thereby realizing the assembly and fixing between the support base 302 and the slide 301. At the same time, the bolts also facilitate the disassembly and assembly of the support base 302 and the slide 301.

[0036] The support structure 3 also includes a detachable top cover 303 mounted on the support base 302. The top cover 303 is positioned above the lug shaft 2. Furthermore, the top cover 303 is mounted on the support base 302 and is located above the lug shaft 2, abutting against the lug shaft 2. The cooperation between the top cover 303 and the support base 302 provides stable support for the lug shaft 2, thereby ensuring that the lug shaft 2 will not vibrate during rotation.

[0037] The lower surface of the top cover 303 is provided with a covering groove 3031 that cooperates with the support groove 3021. The covering groove 3031 abuts against the lug shaft 2. Furthermore, the covering groove 3031 has a semi-circular structure. The covering groove 3031 and the support groove 3021 are connected to form a circular structure that is adapted to the lug shaft 2.

[0038] The top cover 303 has first mounting holes 3032 at both ends for assembly with the support base 302. The support base 302 has second mounting holes 3022 at both ends that mate with the first mounting holes 3032. Furthermore, the first mounting holes 3032 are arranged along the thickness direction of the top cover 303 and are located at opposite ends of the top cover 303. The support base 302 has second mounting holes 3022 corresponding to the first mounting holes 3032 and are located at opposite ends of the support base 302. Bolts are used to assemble and fix the top cover 303 and the support base 302 through the first mounting holes 3032 and the second mounting holes 3022.

[0039] The top cover 303 has mounting grooves 3033 at both ends for assembly with the support base 302. The mounting grooves 3033 are located on the lower surface of the top cover 303. The support base 302 has mounting protrusions 3023 that cooperate with the mounting grooves 3033. Furthermore, the mounting grooves 3033 are located at the corners of the bottom surfaces at both ends of the top cover 303, and the mounting protrusions 3023 are located on the top surfaces at both ends of the support base 302. When the top cover 303 and the support base 302 are assembled together, the mounting protrusions 3023 are located in the corresponding mounting grooves 3033. The cooperation between the mounting protrusions 3023 and the mounting grooves 3033 makes the connection between the top cover 303 and the support base 302 stable, and there will be no relative movement between the top cover 303 and the support base 302, which improves the stability of the support structure 3 in supporting the lug shaft 2.

[0040] Additionally, it should be noted that without the use of lubricant, two semi-circular bearings can also be used as a medium to reduce friction. Specifically, semi-circular bearings are installed in the support groove 3021 and the assembly groove 3033 respectively. The inner ring of the semi-circular bearing abuts against the lug shaft 2, and the outer ring is fixed in the support groove 3021 or the assembly groove 3033. When the top cover 303 and the support seat 302 are assembled together, the two semi-circular bearings are spliced ​​into a complete bearing, thereby reducing the friction between the lug shaft 2 and the support structure 3 through the two semi-circular bearings. However, using two semi-circular bearings will increase the cost of the support structure.

[0041] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention; therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.

[0042] Although this document frequently uses reference numerals from the figures, such as base 1, bearing seat 101, lug shaft 2, support structure 3, slide 301, fixing hole 3012, second mounting hole 3013, support seat 302, support groove 3021, second assembly hole 3022, assembly protrusion 3023, first mounting hole 3024, lubrication hole 3025, top cover 303, cover groove 3031, first assembly hole 3032, and assembly groove 3033, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
