Description

Technical Field

[0001] The utility model relates to the technical field of loom accessories, in particular to a loom ear wire disc assembly. Background Art

[0002] The principle of a loom is actually to weave yarn and warp yarn together to form a fabric. The ear wire disc assembly in the loom plays the important function of rolling the edge of the cloth, making the edge of the cloth tighter and not easy to fall apart.

[0003] The planetary gears and center gear of the existing ear wire disk assembly will wear out after working for a period of time, affecting the normal operation of the loom, which requires frequent replacement of the planetary gears and center gears, resulting in high equipment maintenance costs. Therefore, in the existing technology, a set of intermediate gears are usually installed between the planetary gears and the center gear. The intermediate gears are made of plastic or metal with a lower hardness than the planetary gears and the center gear. The planetary gears and the center gear are protected by wearing the intermediate gears, but this also requires more frequent replacement of the intermediate gears, affecting the production efficiency of the loom. Utility Model Content

[0004] In order to overcome the above-mentioned defects in the prior art, the utility model provides a loom ear wire disc assembly.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a loom ear wire disk assembly, including a webbing gear, the webbing gear is provided with a center hole located at the axis of the webbing gear, and two mounting holes are respectively located on both sides of the webbing gear, a center shaft is rotatably installed in the center hole, ear wire wheel frames are rotatably installed in two groups of the mounting holes, a center wheel is fixedly installed on the center shaft, and planetary wheels are fixedly installed on the two groups of the ear wire wheel frames, and the center wheel and the planetary wheels are tensioned by a synchronous belt.

[0006] Furthermore, a threaded portion is provided at one end of the ear screw wheel frame close to the center wheel, and the planetary gear is fixedly mounted on the ear screw wheel frame by a fastening nut, and the diameter of the planetary gear is smaller than the diameter of the center wheel.

[0007] Furthermore, the inner side of the synchronous belt is provided with meshing teeth matching the planetary gears and the center gear.

[0008] Furthermore, a first anti-slip platform is provided at one end of the central wheel away from the selvedge gear, and a second anti-slip platform is provided at one end of the planetary wheel close to the selvedge gear.

[0018] In order to more clearly illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings. Obviously, the drawings described below are only one embodiment of the present invention. For ordinary technicians in this field, without paying any creative work, other embodiments can be obtained based on these drawings and embodiments, which all fall within the scope of protection of the present invention.

[0019] according to Figure 1-4As shown, a loom ear wire disc assembly includes a selvedge gear 1. The selvedge gear 1 is provided with a center hole 11 located at the axis center of the selvedge gear 1 and two mounting holes 12 respectively located on both sides of the selvedge gear 1. A center shaft 2 is rotatably mounted in the center hole 11 through a bearing. Ear wire wheel frames 3 are rotatably mounted in two groups of mounting holes 12 through bearings. A center wheel 4 is fixedly mounted on the center shaft 2 through a key. Planetary gears 5 are fixedly mounted on the two groups of ear wire wheel frames 3. The center wheel 4 and the planetary gears 5 are tensionedly connected by a synchronous belt 6.

[0020] In this embodiment, a threaded portion 31 is provided at one end of the ear screw wheel frame 3 close to the center wheel 4 , and the planetary gear 5 is fixedly mounted on the ear screw wheel frame 3 by a fastening nut 7 . The diameter of the planetary gear 5 is smaller than that of the center wheel 4 .

[0021] In this embodiment, meshing teeth 61 matching the planetary gears 5 and the center gear 4 are provided on the inner side of the synchronous belt 6 , and the meshing teeth 61 of the synchronous belt 6 are meshed with the center gear 4 and the planetary gears 5 .

[0022] In this embodiment, a first anti-slip platform 41 is provided at the end of the center wheel 4 away from the webbing gear 1, and a second anti-slip platform 51 is provided at the end of the planetary wheel 5 close to the webbing gear 1. The synchronous belt 6 is installed between the first anti-slip platform 41 and the second anti-slip platform 51, and the anti-slip platform prevents the synchronous belt 6 from falling off.

[0023] In this embodiment, a sealing cover 8 is clamped on the end of the center hole 11 away from the center wheel 4, and an oiling nozzle 9 is installed on the end of the sealing cover 8 away from the center hole 11 through threaded cooperation. An oil guide tube 81 is provided on the end of the sealing cover 8 close to the center hole 11, and an oil storage chamber 21 corresponding to the position of the oil guide tube 81 is provided on the end of the center shaft 2. The oil guide tube 81 is inserted into the oil storage chamber 21. By storing lubricating oil in the oil storage chamber 21, the frequency of oiling can be reduced. When the ear thread disk is working, the lubricating oil is slowly released from the oil storage chamber 21 into the center hole 11 to lubricate the bearings inside the selvage gear 1.

[0024] In this embodiment, the center hole 11 and the mounting hole 12 are connected to each other through the oil guide hole 13. When the selvage gear 1 rotates, the lubricating oil in the center hole 11 enters the mounting hole 12 through the oil guide hole 13 under the action of centrifugal force, thereby lubricating the bearing in the mounting hole 12.

[0025] When the present invention is in use, the center shaft 2 is fixedly mounted on the fixed frame of the ear wire disk, and the driving mechanism on the loom drives the selvage gear 1 to rotate, so that the planetary gear 5 rotates around the center wheel 4. Under the action of the center wheel 4, the synchronous belt 4 rotates, and the planetary gear 5 is driven to rotate by the synchronous belt 4. When the planetary gear 5 rotates, it will drive the ear wire wheel frame 3 to rotate, thereby replacing the intermediate gear in the prior art with the synchronous belt 6. The synchronous belt 6 has the characteristics of low manufacturing cost and easy disassembly and assembly, which reduces the time taken for equipment maintenance and is beneficial to improving the production efficiency of the loom. In addition, when lubricating the ear wire disk assembly, the lubricating oil is injected into the oil storage chamber 21 through the oiling nozzle 9. The oil storage chamber 21 can store lubricating oil, thereby reducing the frequency of oiling and thus reducing the number of maintenance. When the selvage gear 1 rotates, the lubricating oil in the center hole 11 enters the mounting hole 12 through the oil guide hole 13 under the action of centrifugal force. Therefore, the staff does not need to add lubricating oil to the mounting hole 12, which simplifies the working steps of oiling and lubrication, and is beneficial to reducing the workload of the staff.

[0026] The above embodiments are merely exemplary embodiments of the present invention and are not intended to limit the scope of the present invention. The scope of protection of the present invention is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the spirit and scope of protection of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the scope of protection of the present invention.
