Description

Technical Field

[0001] This utility model belongs to the field of weaving equipment, specifically relating to a circular loom. Background Technology

[0002] A circular loom is an industrial device used for weaving tubular fabric. The tubular fabric is woven from warp and weft threads, with the warp threads threaded through the holes in the heddles. The reciprocating motion of the heddles drives the heddles and the warp threads threaded within them to move up and down. The weft threads pass through the reciprocating warp threads to form the tubular fabric. Currently, circular looms typically use a flat cam mounted on the main shaft. As the flat cam rotates, it drives the end of a rocker arm to move up and down, which in turn drives the heddles connected to the end of the rocker arm to move up and down.

[0003] However, in existing circular looms, the contact between the planar cam and the rocker arm is a high-pair contact, and the stress at the contact position is relatively large, which causes severe wear on the planar cam and the rocker arm. Once the planar cam is damaged, it will cause the circular loom to stop, which will seriously affect the production efficiency. When the planar cam is running at high speed, the planar cam and the rocker arm will also cause large vibrations and noise due to impact and friction, resulting in high noise during the production process. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a circular loom to solve the problem of high noise and easy damage in the structure used to drive the heald belt assembly to move up and down in the circular loom.

[0005] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: A circular loom includes a frame with a chassis, a main shaft axially positioned on the chassis, and multiple heald belt assemblies. The multiple heald belt assemblies are mounted on the frame and distributed around the chassis. It also includes: a linear drive assembly having an input shaft and an output rod; a through hole on the heald belt assembly, through which the output rod passes to drive the heald belt assembly to reciprocate up and down; and a gear assembly including a driving bevel gear, a driven bevel gear, and multiple transmission gears. The main shaft is connected to the driving bevel gear to drive it to rotate. The driven bevel gear meshes with the driving bevel gear and is connected to any of the transmission gears via a connecting rod. The multiple transmission gears are respectively mounted on each input shaft to drive the input shaft to rotate, and the transmission gears transmit power through meshing. This technical solution has the following technical effects:

[0006] This invention utilizes a linear drive assembly and a gear assembly to drive the main shaft to the heald belt assembly. The meshing driving and driven bevel gears convert the vertical rotation of the main shaft into horizontal rotation, which in turn drives at least one of the transmission gears mounted on each input shaft to rotate via a connecting rod. Other transmission gears mesh with each other and with the rotating transmission gears to achieve synchronous rotation of all transmission gears, thereby driving all input shafts to rotate synchronously. The linear drive assembly converts the rotation of the input shafts into an output rod that drives the heald belt assembly to reciprocate up and down, thus transmitting power. The combination of the gear assembly and the linear drive assembly satisfies transmission requirements while offering advantages such as compact structure, stable and reliable transmission. Furthermore, both the internal transmission of the gear assembly and the internal transmission of the linear drive assembly exhibit low transmission noise. The gear assembly drives the input shafts of each linear drive assembly to rotate via transmission gears, achieving transmission between the gear assembly and the linear drive assembly. This transmission process avoids impact and wear between the gear assembly and the linear drive assembly, thus preventing excessive noise generated during transmission due to impact and wear, and extending the service life of both the gear assembly and the linear drive assembly.

[0007] In the aforementioned circular loom, multiple driven bevel gears are provided, each connected to a different transmission gear via a connecting rod. This allows the driving bevel gear to simultaneously drive more than one driven bevel gear when rotating, thereby causing the transmission gears connected to each driven bevel gear to rotate together. The multiple driven bevel gears driving all the transmission gears through multiple transmission gears significantly reduce the load on individual transmission gears, preventing damage from excessive loads on the driven bevel gears and their connected transmission gears, and extending the service life of both the driven bevel gears and the transmission gears.

[0008] In the aforementioned circular loom, multiple sets of transmission gears are provided, each set independently. The driving bevel gear drives each set of transmission gears to rotate through different driven bevel gears. When the driving bevel gear rotates, it can drive each set of transmission gears to rotate through different driven bevel gears. By grouping the transmission gears, different driven bevel gears can drive a small number of transmission gears to rotate, thereby improving transmission efficiency.

[0009] In the aforementioned circular loom, the driving bevel gear includes a first driving bevel gear and a second driving bevel gear arranged coaxially. The tooth surfaces of the first and second driving bevel gears are arranged opposite each other to mesh with different driven bevel gears located between them. This allows a large number of driven bevel gears to be accommodated between the first and second driving bevel gears, meaning that the driving bevel gear can mesh with more driven bevel gears while saving space and avoiding mutual interference between driven bevel gears in the transmission.

[0010] In the aforementioned circular loom, an annular baffle is provided on the chassis, surrounding the main shaft to form a cavity for accommodating the driving and driven bevel gears. The annular baffle also has limiting holes for the connecting rod to pass through. The annular baffle allows for support and radial limitation of the connecting rod through the limiting holes, preventing radial movement of the connecting rod and ensuring stable transmission at both ends, thus making the transmission more stable and reliable.

[0011] In the aforementioned circular loom, a limit bearing is embedded in the limit hole, and the connecting rod passes through the limit bearing. This prevents mutual wear between the rotating connecting rod and the annular baffle, thereby extending the service life of the connecting rod.

[0012] In the aforementioned circular loom, the annular baffle comprises multiple flat plates, which are spliced ​​together to form the annular baffle. By breaking down the heavier annular baffle into multiple lighter flat plates, the manufacturing difficulty of the annular baffle is reduced. Furthermore, during installation, workers can install the lighter flat plates one by one onto the chassis, reducing the assembly difficulty between the annular baffle and the chassis.

[0013] In the aforementioned circular loom, the bottom of the flat plate is provided with an insertion protrusion, and the base plate is provided with insertion holes. The flat plate is inserted into the insertion holes on the base plate through the insertion protrusion and locked to the frame by locking screws. The insertion protrusion, by engaging with the insertion holes, positions the flat plate for installation, allowing each flat plate to be quickly installed into place to form a ring baffle. It also aligns the limiting holes on the flat plate with the transmission gear equipped with a connecting rod, facilitating assembly. The locking screws further position the flat plate, ensuring it stands stably on top of the base plate, making the installation more stable and reliable.

[0014] In the aforementioned circular loom, the linear drive assembly includes a planetary mechanism and a connector. The planetary mechanism has planetary gears and an input shaft. The input shaft is connected to the planetary gears to drive them to revolve around the input shaft and rotate on their own axis. One end of the connector is rotatably connected to the central shaft of the planetary gears, and the other end has an output rod passing through the through hole. The linear drive assembly, through the planetary mechanism and connector, converts the rotation of the input shaft into the reciprocating motion of the heald belt assembly driven by the connector, thus realizing power transmission. It has the advantages of compact structure and stable and reliable transmission.

[0015] In the aforementioned circular loom, the loom further includes an upper gate ring and a lower gate ring fixed on the frame, as well as multiple grid plates connected between the upper and lower gate rings. Adjacent grid plates form a threading gap for passing warp threads. The upper and lower ends of the grid plates are respectively mounted on the upper and lower gate rings, and the thickness of the grid plates gradually decreases from the upper and lower ends towards the center. By making the ends of the grid plates thicker, the connection strength between the grid plates and the upper and lower gate rings can be enhanced. By making the middle portion of the grid plates thinner, the distance between the two grid plates can be increased, resulting in a larger width in the middle of the threading gap. This makes it less likely for the warp threads to come into contact with the grid plates and wear when passing through the threading gap, reducing the possibility of warp thread fuzzing, splitting, or breakage, ensuring warp thread strength, and reducing dust generation.

[0016] The features and advantages of this utility model will be disclosed in detail in the following specific embodiments and accompanying drawings. Attached Figure Description

[0032] This utility model discloses a circular loom, including a frame with a chassis, a main shaft axially positioned on the chassis, and multiple heald belt assemblies. The multiple heald belt assemblies are mounted on the frame and distributed around the chassis. It also includes: a linear drive assembly comprising a planetary mechanism and a connector; the planetary mechanism has planetary gears and an input shaft, the input shaft being connected to the planetary gears to drive the planetary gears to revolve around the input shaft and rotate on their own axis; the heald belt assemblies have through holes; one end of the connector is connected to the central shaft of the planetary gears, and the other end passes through the through hole to drive the heald belt assemblies to reciprocate up and down; and a gear assembly including a driving bevel gear, a driven bevel gear, and multiple transmission gears; the main shaft is connected to the driving bevel gear to drive its rotation; the driven bevel gear meshes with the driving bevel gear and is linked to any of the transmission gears via a connecting rod; the multiple transmission gears are respectively mounted on each input shaft to drive its rotation, and the transmission gears are driven by meshing. This invention utilizes a linear drive assembly and a gear assembly to drive the main shaft to the heald belt assembly. The meshing driving and driven bevel gears convert the vertical rotation of the main shaft into horizontal rotation, which in turn drives at least one of the transmission gears mounted on each input shaft to rotate via a connecting rod. Other transmission gears mesh with each other and with the rotating transmission gears to achieve synchronous rotation of all transmission gears, thereby driving all input shafts to rotate synchronously. The linear drive assembly, through a planetary mechanism and connecting members, converts the rotation of the input shafts into the reciprocating motion of the heald belt assembly driven by the connecting members, thus achieving power transmission. The combination of the gear assembly and the linear drive assembly satisfies transmission requirements while offering advantages such as compact structure, stable and reliable transmission. Furthermore, both the internal transmission of the gear assembly and the internal planetary mechanism of the linear drive assembly exhibit low transmission noise. The gear assembly drives the input shafts of each linear drive assembly to rotate through the transmission gears, thereby realizing the transmission between the gear assembly and the linear drive assembly. This transmission process can avoid impact and wear between the gear assembly and the linear drive assembly, thus preventing the generation of a lot of noise due to impact and wear during transmission, and at the same time extending the service life of the gear assembly and the linear drive assembly.

[0038] Example 1:

[0039] A circular loom, such as Figures 1 to 6 As shown, the system includes a frame 100, a motor 200, a spindle 210, and multiple heald belt assemblies 300. A chassis 110 is mounted on the frame 100. The motor 200 is mounted on the lower part of the chassis 110 to drive the spindle 210 to rotate. The spindle 210 is axially positioned on the chassis 110 and coaxially arranged with it. Multiple heald belt assemblies 300 are mounted on the frame 100 and distributed around the chassis 110. The system also includes a linear drive assembly 400 and a gear assembly. The linear drive assembly 400 is connected to the heald belt... Components 300 are set up one-to-one. The linear drive component 400 is connected between the gear component and the heald belt component 300. The main shaft 210 transmits rotation to the linear drive component 400. The linear drive component 400 converts the rotational motion into linear motion and then transmits it to the heald belt component 300 to drive the heald belt component 300 to move up and down reciprocally. This causes the warp threads in the healds of the heald belt component 300 to move up and down reciprocally with the healds, and the weft threads pass through the moving warp threads to weave the tubular fabric.

[0040] The linear drive assembly 400 includes a planetary mechanism 410 and a connector 420. The planetary mechanism 410 can be of various types, as long as it has planetary gears 411 and an input shaft 412, and satisfies the requirement that the planetary gears 411 revolve around the input shaft 412 and rotate on their own axis under the drive of the input shaft 412. The heddle assembly 300 has a through hole. One end of the connector 420 is connected to the central axis of the planetary gears 411, and the output rod at the other end passes through the through hole. In this embodiment, the planetary mechanism 410 includes a gear ring 413, planetary gears 411, an input shaft 412, and a transmission member 414. The planetary gears 411 are disposed inside the gear ring 413, and their outer circumferences mesh with the gear ring 413. The input shaft 412 is coaxially arranged with the gear ring 413. One end of the transmission member 414 is fixed to the end of the input shaft 412, and the other end is rotatably connected to the central axis of the planetary gears 411 to drive the planetary gears 411 to rotate within the gear ring 413. When the input shaft 412 drives the planetary gear 411 to rotate within the gear ring 413, as the planetary gear 411 meshes with the gear ring 413 at different positions, the planetary gear 411 rotates on its own axis while revolving around the central axis of the gear ring 413. This causes the connecting piece 420, which is rotatably connected to the planetary gear 411, to rotate around the central axis of the planetary gear 411 and simultaneously undergo displacement in both the horizontal and vertical directions. Because one end of the connecting piece 420 passes through the through hole of the heald assembly 300, the heald assembly 300 can only move in the vertical direction. Therefore, the heald assembly 300 can guide the end of the connecting piece 420 inserted into the heald assembly 300 through the through hole, so that the connecting piece 420 can only transmit the vertical displacement to the heald assembly 300, thereby driving the heald assembly 300 to reciprocate up and down.

[0041] The gear assembly includes a driving bevel gear 510, a driven bevel gear 520, and multiple transmission gears 530. The driving bevel gear 510 is sleeved on the main shaft 210. When the main shaft 210 rotates, it drives the driving bevel gear 510 to rotate synchronously. The driven bevel gear 520 meshes with the driving bevel gear 510 to change the direction of rotation, converting the vertical rotation of the main shaft 210 and the driving bevel gear 510 into the horizontal rotation of the driven bevel gear 520. The driven bevel gear 520 is connected to any transmission gear 530 through a connecting rod 540. The transmission gears 530 are correspondingly sleeved on the ends of the input shafts 412 of each linear drive assembly 400 and are connected to the input shafts 412. The transmission gears 530 mesh with each other to achieve the linkage of the transmission gears 530. When the main shaft 210 rotates, it drives the driving bevel gear 510 to rotate synchronously, which in turn drives the driven bevel gear 520, which meshes with the driving bevel gear 510, to rotate. The driven bevel gear 520 drives any transmission gear 530 to rotate through the connecting rod 540. Other transmission gears 530 achieve synchronous rotation of all transmission gears 530 by meshing with the transmission gear 530 and meshing with each other, thereby achieving synchronous rotation of all input shafts 412. Finally, the rotational motion of the input shaft 412 is converted into reciprocating motion in the vertical direction of the belt assembly 300 through the linear drive assembly 400.

[0042] This invention utilizes a linear drive assembly 400 and a gear assembly to drive the main shaft 210 to the helical belt assembly 300. The meshing driving bevel gear 510 and driven bevel gear 520 convert the vertical rotation of the main shaft 210 into horizontal rotation, which in turn drives at least one of the transmission gears 530 mounted on each input shaft 412 to rotate via a connecting rod 540. The other transmission gears 530 mesh with each other and with the rotating transmission gear 530, achieving synchronous rotation of all transmission gears 530, thereby driving all input shafts 412 to rotate synchronously. The linear drive assembly 400, through a planetary mechanism 410 and a connecting member 420, converts the rotation of the input shafts 412 into the reciprocating motion of the helical belt assembly 300 driven by the connecting member 420, thus achieving power transmission. The combination of the gear assembly and the linear drive assembly 400 satisfies transmission requirements while offering advantages such as compact structure, stable and reliable transmission. Furthermore, both the internal transmission of the gear assembly and the transmission of the planetary mechanism 410 within the linear drive assembly 400 have the advantage of low transmission noise. The gear assembly drives the input shaft 412 of each linear drive assembly 400 to rotate through the transmission gear 530, thereby realizing the transmission between the gear assembly and the linear drive assembly 400. This transmission process can avoid collision and wear between the gear assembly and the linear drive assembly 400, thereby preventing a lot of noise from being generated by collision and wear between the gear assembly and the linear drive assembly 400 during the transmission process, and at the same time, extending the service life of the gear assembly and the linear drive assembly 400.

[0043] There can be one or more driven bevel gears 520 (two or more). In this embodiment, there are multiple driven bevel gears 520. The multiple driven bevel gears 520 mesh with the driving bevel gear 510 respectively, and the multiple driven bevel gears 520 are connected to different transmission gears 530 through connecting rods 540. This allows the driving bevel gear 510 to drive more than one driven bevel gear 520 to rotate simultaneously when it rotates, thereby driving the transmission gears 530 connected to each driven bevel gear 520 to rotate together. The multiple driven bevel gears 520 drive all the transmission gears 530 to rotate through the multiple transmission gears 530, which can greatly reduce the load on a single transmission gear 530, avoid damage to the driven bevel gears 520 and the transmission gears 530 connected to them due to excessive load, and extend the service life of the driven bevel gears 520 and the transmission gears 530.

[0044] The transmission gears 530 can mesh sequentially for transmission, or they can be grouped for transmission. In this embodiment, the transmission gears 530 are preferably divided into multiple groups, each group including several transmission gears 530. The multiple groups of transmission gears 530 are set independently, that is, the transmission gears 530 in adjacent groups do not mesh. Each group of transmission gears 530 is connected to the driving bevel gear 510 through at least one driven bevel gear 520. When the driving bevel gear 510 rotates, it can drive each group of transmission gears 530 to rotate through different driven bevel gears 520. By grouping the transmission gears 530, different driven bevel gears 520 can drive a small number of transmission gears 530 to rotate, thereby improving the transmission efficiency.

[0045] like Figure 1 and Figure 2 As shown, in this embodiment, the driving bevel gear 510 includes a first driving bevel gear 511 and a second driving bevel gear 512. The first driving bevel gear 511 and the second driving bevel gear 512 are coaxially arranged on the main shaft 210. The tooth surfaces of the first driving bevel gear 511 and the second driving bevel gear 512 are arranged opposite each other, forming a certain height gap between them. All driven bevel gears 520 are arranged in this gap. A portion of the driven bevel gears 520 mesh with the first driving bevel gear 511, and another portion of the driven bevel gears 520 mesh with the second driving bevel gear 512. The driven bevel gears 520 meshing with the first driving bevel gear 511 and the driven bevel gears 520 meshing with the second driving bevel gear 512 are arranged in a staggered manner, so that a large number of driven bevel gears 520 can be accommodated between the first driving bevel gear 511 and the second driving bevel gear 512. That is, the driving bevel gear 510 can mesh with more driven bevel gears 520 while saving space and avoiding mutual interference between the driven bevel gears 520 in the transmission.

[0046] In this embodiment, an annular baffle 600 is provided on the chassis 110. The annular baffle 600 surrounds the main shaft 210 to form a receiving cavity 620 located above the chassis 110. Both the driving bevel gear 510 and the driven bevel gear 520 are located within the receiving cavity 620. A limiting hole 630 is provided on the annular baffle 600. One end of the connecting rod 540 is connected to the driven bevel gear 520, and the other end of the connecting rod 540 passes through the limiting hole 630 and is connected to the transmission gear 530, so that the two can move together. The annular baffle 600 is provided so that it can support and radially limit the connecting rod 540 through the limiting hole 630, so as to prevent the connecting rod 540 from moving radially and affecting the stable transmission at both ends of the connecting rod 540, thus making the transmission more stable and reliable. In order to prevent mutual wear between the rotating connecting rod 540 and the annular baffle 600 and extend the service life of the connecting rod 540, this embodiment preferably has a limit bearing 640 embedded in the limit hole 630, and the connecting rod 540 passes through the limit bearing 640.

[0047] In this embodiment, the annular baffle 600 includes multiple flat plates 610, which are spliced ​​together to form the annular baffle 600, arranged around the main shaft 210. By breaking down the relatively heavy annular baffle 600 into multiple lighter flat plates 610, the manufacturing difficulty of the annular baffle 600 is reduced. This also allows workers to install the lighter flat plates 610 one by one onto the chassis 110 during installation, reducing the assembly difficulty between the annular baffle 600 and the chassis 110. Preferably, the bottom of the plate 610 is provided with a plug-in protrusion 611, and the chassis 110 is provided with a plug hole 111. When the plate 610 is installed on the chassis 110, the plug-in protrusion 611 is plugged into the plug hole 111, and the locking screw passes through the chassis 110 and locks with the bottom of the plate 610. The plug-in protrusion 611 can cooperate with the plug hole 111 to install and position the plate 610, so that each plate 610 can be quickly installed in place to form an annular baffle 600, and the limiting hole 630 on the plate 610 is aligned with the transmission gear 530 with the connecting rod 540, which is convenient for assembly. The locking screw can further position the plate 610, so that the plate 610 stands stably on the top of the chassis 110, and the installation is more stable and reliable.

[0048] like Figure 1 As shown, the circular loom also includes an upper gate ring 710, a lower gate ring 720, and multiple grid plates 730. The upper gate ring 710 and the lower gate ring 720 are fixed on the frame 100, with the upper gate ring 710 located above the lower gate ring 720. The grid plates 730 connect the upper gate ring 710 and the lower gate ring 720. The upper end of the grid plate 730 is mounted on the upper gate ring 710, and the lower end of the grid plate 730 is mounted on the lower gate ring 720. A threading gap is formed between adjacent grid plates 730 to allow the warp threads to pass through. The grid plates 730 are provided with grooves 731, and the grooves 731 of all the grid plates 730 together form an annular shuttle raceway. Figure 5 As shown, the thickness of the grid plate 730 gradually decreases from the top and bottom ends towards the center, so that the two sides of the grid plate 730 are set with arc-shaped surfaces. The thickness of the two ends of the grid plate 730 is defined as H1, and the thickness of the middle position of the grid plate 730 is defined as H2. Then H1>H2, that is, the grid plate 730 is a sheet structure that is thick at both ends and thin in the middle. By making the two ends of the grid plate 730 thicker, the connection strength between the grid plate 730 and the upper door ring 710 and the lower door ring 720 can be enhanced. By making the middle position of the grid plate 730 thinner, the distance between the two grid plates 730 can be increased, so that the width of the middle position of the threading gap is larger. In this way, when the warp thread passes through the threading gap, it is not easy to come into contact with the grid plate 730 and wear it. This reduces the possibility of warp thread fuzzing, splitting or breaking, ensures the strength of the warp thread, and reduces the generation of dust.

[0049] In this preferred embodiment, the upper door ring 710 and the lower door ring 720 are each divided into multiple segments, such as... Figure 4 As shown, multiple grid plates 730 are connected between each upper gate ring 710 and lower gate ring 720. That is, by dividing the upper gate ring 710, lower gate ring 720 and grid plates 730 with shuttle runways into multiple modules with the same structure, the weight of each module is small, so as to reduce the overall assembly difficulty.

[0050] 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.
