Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, and more specifically, it relates to an electric drive device for a folding edge device. Background Technology

[0002] A selvage folding device is an auxiliary device used on shuttleless looms such as rapier, projectile, or air-jet looms to produce finished selvage fabrics. Because shuttleless looms use external weft feeding, the weft yarn bobbin is located at rest outside the weft hole. After the weft yarn is cut by scissors, a small section of the weft yarn protrudes outside the fabric edge, becoming a raw selvage. With a selvage folding device installed, a hook can be used to hook the protruding weft yarn into the weft hole, and then the weft beating action of the loom weaves the yarn into the selvage to form a neat, finished edge, resulting in a comfortable and beautiful fabric appearance. Therefore, selvage folding devices are often used in the weaving of high-end fabrics.

[0003] A novel folding-in device for a high-speed loom, disclosed in CN211897267U, includes a housing mechanism, an inner groove cam mechanism, a swing arm mechanism, and a scissor hook mechanism. The inner groove cam mechanism is fixed inside the housing mechanism by bearings. The swing arm mechanism is installed and fixed on the swing arm mechanism by an oil seal, an oil seal seat, and the scissor hook mechanism. The inner groove cam mechanism consists of two sets of inner groove cams, a main shaft, a retaining ring, a key, an oil seal, a needle roller bearing, a bearing inner sleeve, a retaining ring, a retaining ring, a positioning ring, a bearing, and a nut. The main shaft is screwed to the inner groove cam by an oil seal, a needle roller bearing, a retaining ring, a bearing inner sleeve, a retaining ring, a key, and a nut. The inner groove cam is provided with a retaining ring. The other side of the inner groove cam is provided with a positioning ring and a bearing, which are fixed by a nut.

[0004] In actual transmission, the folding edge device is powered by the main machine (i.e., the loom), and a series of mechanical parts are used to transmit the power to the main shaft of the folding edge device, so as to achieve linkage between the folding edge device and the main machine and complete a series of folding edge processing actions. However, due to the different power sources of various models and the shortage of space, a large number of parts are required and the requirements are high, resulting in high cost and complicated assembly. Utility Model Content

[0005] The purpose of this invention is to provide an electric drive device for a folding edge device in order to solve the above-mentioned problems.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an electric drive device for a folding edge device, comprising: a housing, on which a main shaft is rotatably connected, and on which a driven helical gear is fixedly mounted; a first support plate, fixedly mounted to the side of the housing by screws, the first support plate having a through hole coaxial with the main shaft, and a second support plate fixedly connected to the side of the first support plate by screws, the second support plate being perpendicular to the first support plate; a drive motor, fixedly connected to the second support plate by screws, and on the output shaft of the drive motor having a driving helical gear meshing with the driven helical gear; wherein, a fixing assembly for synchronizing the movement of the main shaft and the driven helical gear, and between the output shaft and the driving helical gear, are provided, the fixing assembly including a limiting member and a fixing member for circumferentially and axially limiting the driven helical gear and the driving helical gear respectively, the limiting member being integrally formed on the main shaft and the output shaft.

[0007] Preferably, both sides of the driven helical gear and the driving helical gear are provided with an inner groove and a fixing groove, and a limiting through groove located on the inner ring of the driven helical gear and the driving helical gear is provided between the inner groove and the fixing groove. The limiting member includes an abutment ring for embedding into the inner groove and a limiting straight bar for inserting into the limiting through groove.

[0008] Preferably, the fixing component consists of a positioning plate and a positioning bolt. The positioning bolt passes through the positioning plate and is threadedly connected to the end faces of the main shaft and the output shaft so that the positioning plate is fixedly installed in the fixing groove.

[0009] Preferably, the helix angle of the driving helical gear is 20°-25°.

[0010] Preferably, the driven helical gear and the driving helical gear are interleaved at 90°.

[0011] In summary, this utility model has the following beneficial effects:

[0012] This invention, by employing an independent drive motor as its power source, completely eliminates the reliance on the main loom for power. This allows the selvage folding device to be adapted to more machine models, making its coordination with the main loom more flexible and the overall structure more compact. It can meet the requirements of compact installation space, thus enabling it to reliably and stably complete the hooking and folding of the weft yarn head during actual weaving, ensuring neat and beautiful selvage. Furthermore, it simplifies the traditional complex transmission chains, transmission shafts, and other components, significantly reducing the number of parts and thus lowering manufacturing costs and assembly difficulty. In addition, compared with traditional chain or belt drives, helical gear transmission has higher transmission efficiency and lower noise levels, improving practicality. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1-3 As shown, an electric drive device for a folding edge device includes a housing 1, a main shaft 2 rotatably connected to the housing 1, a driven helical gear 52 fixedly mounted on the main shaft 2, a first support plate 31 fixedly mounted on the side of the housing 1 by screws, the first support plate 31 having a through hole coaxially arranged with the main shaft 2, a second support plate 32 fixedly connected to the side of the first support plate 31 by screws, the second support plate 32 being perpendicular to the first support plate 31, a drive motor 4 fixedly connected to the second support plate 32 by screws, and a driving helical gear 51 meshing with the driven helical gear 52 fixedly mounted on the output shaft of the drive motor 4; wherein, fixing components for synchronous movement are provided between the main shaft 2 and the driven helical gear 52, and between the output shaft and the driving helical gear 51, respectively, the fixing components including limiting members and fixing members for circumferential and axial limiting of the driven helical gear 52 and the driving helical gear 51, respectively, the limiting members being integrally formed on the main shaft 2 and the output shaft.

[0019] Understandably, by using an independent drive motor 4 as the power source, the reliance on the main loom for power is completely eliminated. This allows the selvage folding device to be adapted to more machine models, making its cooperation with the main loom more flexible and the overall structure more compact. It can meet the requirements of compact installation space, so it can reliably complete the hooking and folding of the weft yarn head in the actual weaving process, ensuring a neat and beautiful selvage. It also simplifies the traditional complex transmission chain, transmission shaft and other components, greatly reducing the number of parts, thereby reducing manufacturing costs and assembly difficulty. In addition, compared with the traditional chain or belt drive, the helical gear drive has higher transmission efficiency and lower noise level, improving practicality.

[0020] Furthermore, both sides of the driven helical gear 52 and the driving helical gear 51 are provided with an inner groove 61 and a fixing groove. A limiting through groove 62 located in the inner ring of the driven helical gear 52 and the driving helical gear 51 is provided between the inner groove 61 and the fixing groove. The limiting member includes an abutment ring 71 for embedding into the inner groove 61 and a limiting straight bar 72 for inserting into the limiting through groove 62.

[0021] Understandably, when installing the driven helical gear 52 and the driving helical gear 51, they are first inserted into their respective shafts along the fit of the limiting straight bar 72 and the limiting through groove 62 and moved until they contact the abutment ring 71, that is, the abutment ring 71 is embedded in the inner groove 61. At this time, the limiting straight bar 72 is located in the limiting through groove 62, realizing circumferential restriction, that is, ensuring the circumferential positioning accuracy between the gear and the shaft.

[0022] Furthermore, the fixing component consists of a positioning plate 8 and a positioning bolt 9. The positioning bolt 9 passes through the positioning plate 8 and is threadedly connected to the end faces of the main shaft 2 and the output shaft so that the positioning plate 8 is fixedly installed in the fixing groove.

[0023] It is understandable that by connecting the positioning plate 8 to the main shaft 2 and the output shaft through the positioning bolt 9, the driven helical gear 52 and the driving helical gear 51 can be firmly fixed to the main shaft 2 and the output shaft respectively, while providing the necessary axial constraint. The double fixing method effectively prevents the gears from loosening when running at high speed.

[0024] Furthermore, the helix angle of the driving helical gear 51 is 20°-25°, and the driven helical gear 52 meshes with the driving helical gear 51 at a 90° angle.

[0025] It is understandable that by using 90° staggered meshing to achieve power steering from the horizontal axis of the drive motor 4 to the vertical axis of the main shaft 2, power loss is reduced by 15%-20% compared to traditional sprocket drive, and operating noise is also reduced.

[0026] Understandably, the driving helical gear 51 adopts a helix angle of 20°-25°. This angle range can ensure the smoothness of transmission and control the axial force within a reasonable range. At the same time, the module of the driven helical gear 52 matches that of the driving gear, and its tooth width is slightly larger than that of the driving gear, which improves the load-bearing capacity and service life of the gear pair.

[0027] It is worth mentioning that the driving helical gear 51 and the driven helical gear 52 are made of high-quality alloy steel and have undergone carburizing and quenching heat treatment, with a surface hardness of HRC58-62, ensuring the wear resistance of the gears during long-term use.

[0028] In summary, this electric drive device has the advantages of simple structure, high transmission efficiency, and convenient maintenance. Its innovative helical gear transmission system and unique fixed component design effectively solve the problems of complexity and bulkiness of traditional devices. It is particularly suitable for use on modern high-speed looms with limited space. This device not only improves the working quality of the folding edge device, but also reduces energy consumption and noise, bringing significant economic and environmental benefits to textile enterprises.

[0029] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
