Description

Technical Field

[0001] This utility model relates to the technical field of textile industry parts, specifically a triangular settling plate fixing ring for a large circular knitting machine. Background Technology

[0002] In the textile industry, the circular knitting machine is the core equipment for knitted fabric production. Its cam sinker is a key component for controlling the movement trajectory of the knitting needles and ensuring the accuracy of the fabric texture. The fixing ring and groove on the surface of the cam sinker need to be precisely adapted to the corresponding parts of the circular knitting machine (such as the cylinder and rollers) to ensure that the cam sinker does not shift or loosen during high-speed operation (typically 1000-3000 r / min), thus avoiding production problems such as yarn breakage and uneven fabric density. However, existing cam sinker fixing rings on circular knitting machines suffer from technical drawbacks in practical applications, including poor adaptability, inconvenient adjustment, and insufficient stability, making it difficult to meet diverse production needs.

[0003] Most existing retaining rings are one-piece molded structures with a fixed and non-adjustable inner diameter. As the variety of textile fabrics increases, circular knitting machines need to replace components such as syringes and rollers of different specifications. At this time, retaining rings with corresponding inner diameters need to be replaced simultaneously. The replacement process requires stopping the machine to disassemble the triangular settling plate and then installing a new retaining ring, which seriously affects production efficiency. Moreover, retaining rings of different specifications need to be purchased and stored separately, increasing equipment maintenance costs and inventory pressure. Some adjustable retaining rings use a bolt-tightening design. During adjustment, the bolts need to be tightened point by point to push the retaining ring to deform. Uneven bolt tightness can easily lead to unbalanced stress and local cracking of the retaining ring. At the same time, the adjustment accuracy depends on manual experience, making it difficult to ensure the matching accuracy between the inner diameter of the retaining ring and the component, thus reducing the reliability of component installation. Utility Model Content

[0004] The purpose of this utility model is to provide a triangular settling plate fixing ring for a large circular knitting machine. This triangular settling plate fixing ring for a large circular knitting machine solves the problems of poor adaptability and inconvenient adjustment and locking of existing triangular settling plate fixing rings for large circular knitting machines.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A triangular settling plate fixing ring for a large circular knitting machine includes a fixing ring disposed on the surface of the triangular settling plate, the surface of which has a circular groove; it also includes a movable component for adjusting the inner diameter of the fixing ring; and a movable component for changing the inner diameter of the circular groove; the movable component includes: a fixing ring fixedly installed on the surface of the triangular settling plate, the fixing ring being rotatably connected to a turntable inside, the turntable being rotatably connected to the top of the fixing ring, a control rod fixedly installed on the outer side of the turntable, a sliding rod slidably connected to the surface of the turntable, an adjusting block fixedly installed on the surface of the sliding rod, an insert rod slidably connected to the surface of the control rod, a return spring fixedly installed on the surface of the insert rod, and the return spring fixedly installed at the bottom of the control rod.

[0006] Preferably, a fixing strip is installed on the outer side of the triangular settlement plate, and a square groove is formed on the surface of the fixing strip, into which the insertion rod is inserted.

[0012] By employing the above technical solution, this utility model provides a triangular settling plate fixing ring for a large circular knitting machine. It possesses at least the following beneficial effects: (1) This utility model achieves precise adjustment through the setting of movable components: pulling up the plug rod on the control lever causes the plug rod to slide against the spring force of the return spring, disengaging from the square groove of the fixed bar and releasing the rotation restriction of the turntable. The multiple square grooves of the fixed bar meet the locking requirements of the turntable at different angles. Holding the control lever causes the turntable to rotate within the fixed ring. The star-shaped groove of the turntable drives the slide rod to slide along the arc groove towards the center. The slide rod drives the six circumferential array adjustment blocks to move synchronously, pushing the fixed ring to elastically deform to adjust the inner diameter. After fitting, releasing the plug rod causes the return spring to push the plug rod back into the square groove, locking the turntable, ensuring the stability of the inner diameter of the fixed ring, and improving the reliability of component installation and the versatility of the device.

[0013] (2) In this utility model, the movable component adjusts the inner diameter of the fixed ring while the movable component adjusts the inner diameter of the circular groove. The movement of the adjusting block drives the outer sliding rod to slide along the strip groove of the connecting plate, and the connecting plate provides stable support to ensure accurate trajectory. The sliding rod drives the fixed plate to move, so that the arc-shaped block at the top of the fixed plate approaches the center of the circular groove. The arc-shaped block is pressed against the inner wall of the circular groove, thereby reducing or expanding the inner diameter of the circular groove. The spiral spring connects the arc-shaped block and the fixed plate, buffering the extrusion force to prevent damage to the circular groove, and also allowing the arc-shaped block to fit tightly against the inner wall, ensuring the adjustment effect and improving work efficiency.

[0016] 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.

[0017] Example 1 A triangular settling plate fixing ring for a large circular kiln, such as Figure 1 - Figure 6 As shown, it includes a fixing ring 2 set on the surface of the triangular settlement plate 1, and a circular groove 3 is formed on the surface of the triangular settlement plate 1; It also includes a movable component 4 for adjusting the inner diameter of the fixed ring 2; The movable component 5 is used to change the inner diameter of the circular groove 3; First, the movable component 4 includes: a fixed ring 41, which is fixedly installed on the surface of the triangular settling plate 1. The fixed ring 41 is rotatably connected to the turntable 42, which is rotatably connected to the top of the fixed ring 2. A control rod 43 is fixedly installed on the outside of the turntable 42. A slide rod 44 is slidably connected to the surface of the turntable 42. An adjusting block 45 is fixedly installed on the surface of the slide rod 44. An insert rod 46 is slidably connected to the surface of the control rod 43. A return spring 47 is fixedly installed on the surface of the insert rod 46. The return spring 47 is fixedly installed at the bottom of the control rod 43. The fixed ring 41 provides stable rotation support for the turntable 42, solving the problem of insufficient adjustment accuracy caused by the offset of the turntable 42 during rotation. The turntable 42 is rotatably connected to the fixed ring 2, and moves in conjunction with the slide rod 44 and the adjusting block 45 on the surface of the turntable 42.

[0018] Secondly, a fixing strip 48 is installed on the outside of the triangular settling plate 1. A square groove 480 is opened on the surface of the fixing strip 48. The insertion rod 46 is inserted into the inside of the square groove 480. Through the insertion and cooperation of multiple square grooves 480 on the surface of the fixing strip 48 and the insertion rod 46, the problem that the traditional fixing ring adjustment device can only lock at a single angle and cannot meet the fixing requirements of different rotation angles of the turntable 42 is solved.

[0019] Furthermore, the surface of the fixed ring 41 is provided with an arc-shaped groove 410, which guides the movement trajectory of the slide rod 44, solving the problem that the slide rod 44 is prone to deviating from the preset path when sliding along the star-shaped groove 420 of the turntable 42. The surface of the turntable 42 is provided with a star-shaped groove 420, which converts the rotational motion of the turntable 42 into the axial reciprocating motion of the slide rod 44 through the inclined trajectory structure of the star-shaped groove 420, solving the problem that the slide rod 44 needs to be driven separately and the operation is cumbersome in the traditional adjustment structure.

[0020] In this embodiment, the movable component 4 enables precise adjustment: pulling up the insert rod 46 on the control lever 43 causes the insert rod 46 to slide against the elastic force of the return spring 47, disengaging from the square groove 480 of the fixing bar 48 and releasing the rotation restriction of the turntable 42. The multiple square grooves 480 of the fixing bar 48 meet the different angle locking requirements of the turntable 42. Holding the control lever 43 causes the turntable 42 to rotate within the fixing ring 41. The star-shaped groove 420 of the turntable 42 drives the slide rod 44 to slide along the arc-shaped groove 410 towards the center. The slide rod 44 drives the six circumferentially arrayed adjustment blocks 45 to move synchronously, pushing the fixing ring 2 to elastically deform and adjust its inner diameter. After fitting, releasing the insert rod 46 causes the return spring 47 to push the insert rod 46 back into the square groove 480, locking the turntable 42 and ensuring the stability of the inner diameter of the fixing ring 2, thus improving the reliability of component installation and the versatility of the device.

[0021] Example 2 like Figure 7 As shown, the moving component 5 includes: a connecting plate 51, which is fixedly installed on the inner side of the fixing ring 41. A strip groove 510 is formed on the surface of the connecting plate 51, and a sliding rod 52 is slidably connected to the inner side of the strip groove 510. The sliding rod 52 is fixedly installed on the outer side of the adjusting block 45.

[0022] Finally, a fixed plate 53 is fixedly installed on the surface of the sliding rod 52. An arc-shaped block 54 is hinged to the top of the fixed plate 53. A spiral spring 55 is fixedly installed at the bottom of the arc-shaped block 54. The spiral spring 55 is fixedly installed on the top of the fixed plate 53. Six adjusting blocks 45 are provided, and all six adjusting blocks 45 are arranged in a circular array with the center point of the fixed ring 41 as the center. Two sets of movable components 4 are provided, and the two sets of movable components 4 are symmetrically arranged with the center line of the triangular settlement plate 1 as the axis of symmetry. The two sets of symmetrically arranged movable components 4 can synchronously adjust the fixed ring 2 from both sides of the triangular settlement plate 1 to avoid uneven deformation of the fixed ring 2 caused by unilateral adjustment.

[0023] In this embodiment, by setting the movable component 5, when the movable component 4 adjusts the inner diameter of the fixed ring 2, the movable component 5 simultaneously changes the inner diameter of the circular groove 3: the movement of the adjusting block 45 drives the outer sliding rod 52 to slide along the strip groove 510 of the connecting plate 51, and the connecting plate 51 provides stable support to ensure accurate trajectory. The sliding rod 52 drives the fixed plate 53 to move, so that the arc-shaped block 54 at the top of the fixed plate 53 is close to the center of the circular groove 3, and the arc-shaped block 54 is pressed against the inner wall of the circular groove 3, thereby reducing or expanding the inner diameter of the circular groove 3. The spiral spring 55 connects the arc-shaped block 54 and the fixed plate 53, buffering the extrusion force to prevent damage to the circular groove 3, and also allowing the arc-shaped block 54 to fit tightly against the inner wall, ensuring the adjustment effect and improving work efficiency.

[0024] In use, the fixed ring 2 of the triangular sinker 1 of this utility model for a large circular knitting machine uses the triangular sinker 1 as the installation base. Through the coordinated action of the movable component 4 and the moving component 5, the inner diameter of the fixed ring 2 and the inner diameter of the circular groove 3 are adjusted respectively, adapting to the installation requirements of large circular knitting machine components of different specifications. This ensures the stable operation of the triangular sinker 1 in textile processing. When the device is not in use, the whole system is in a standby state: the fixed ring 2 fits against the outer side of the circular groove 3 on the surface of the triangular sinker 1, maintaining the initial inner diameter; in the movable component 4, the turntable 42 is in the initial angle inside the fixed ring 41, the slide rod 44 is located at the outer end of the star-shaped groove 420 on the surface of the turntable 42, and the adjusting block 45... The return spring 47 is in a naturally extended state and does not move towards the center of the fixed ring 41. The insertion rod 46 is inserted into the square groove 480 on the surface of the fixed strip 48, restricting the rotation of the turntable 42. In the moving assembly 5, the sliding rod 52 is in the outer initial position in the strip groove 510 of the connecting plate 51. The arc block 54 is kept in an extended state under the support of the spiral spring 55 and does not compress the inner wall of the circular groove 3. At this time, the inner diameter of the fixed ring 2 and the circular groove 3 can be adjusted according to the specifications of the large circular machine parts. When it is necessary to adjust the inner diameter of the fixed ring 2 to adapt to different specifications of parts, precise adjustment can be achieved through the moving assembly 4. Pull the insertion rod 46 on the surface of the control rod 43 upward. Overcoming the elastic force of the return spring 47, the slide upwards, disengaging from the square groove 480 on the surface of the fixing bar 48, thus releasing the rotation restriction on the turntable 42. Multiple square grooves 480 on the fixing bar 48 can meet the locking requirements of different rotation angles of the turntable 42, ensuring stable position after adjustment. Holding the control lever 43 drives the turntable 42 to rotate inside the fixing ring 41, and the star-shaped groove 420 on the surface of the turntable 42 rotates synchronously. Because the slide rod 44 is slidably connected within the star-shaped groove 420, the inclined trajectory of the star-shaped groove 420 drives the slide rod 44 to slide along the trajectory towards the center of the fixing ring 41. The arc-shaped groove 410 on the surface of the fixing ring 41 provides guidance for the movement of the slide rod 44, preventing the slide rod 44 from sliding upwards. The slider 44 moves the surface-fixed adjustment blocks 45 synchronously. The six adjustment blocks 45, arranged in a circular array with the center point of the fixed ring 41 as the center, move synchronously towards the center or the outside in the same direction. The inner side of the adjustment block 45 is in contact with the outer wall of the fixed ring 2. When moving, it pushes the fixed ring 2 to undergo elastic deformation, thereby reducing or expanding the inner diameter of the fixed ring 2. After the inner diameter of the fixed ring 2 is adapted to the target component, the insertion rod 46 is released, and the return spring 47 releases its elastic force to push the insertion rod 46 to be re-inserted into the square groove 480 at the corresponding position, locking the position of the turntable 42, ensuring the stability of the inner diameter of the fixed ring 2, improving the reliability of component installation, adapting to multiple specifications of components, and enhancing the versatility of the device.

[0025] While the movable component 4 adjusts the inner diameter of the fixed ring 2, the moving component 5 moves synchronously, changing the inner diameter of the circular groove 3 on the surface of the triangular sinker 1, achieving coordinated adaptation between the fixed ring 2 and the circular groove 3. When the adjusting block 45 moves, the sliding rod 52 fixed on its outer side slides synchronously along the strip groove 510 on the surface of the connecting plate 51. The connecting plate 51 is fixed inside the fixed ring 41, providing stable moving support for the sliding rod 52, ensuring accurate movement trajectory of the sliding rod 52. The sliding rod 52 drives the fixed plate 53 fixed on the surface to move synchronously. The arc-shaped block 54 at the top of the fixed plate 53 moves closer to the center of the circular groove 3. The arc-shaped block 54 fits against the inner wall of the circular groove 3. When it moves, it squeezes the inner wall of the circular groove 3, causing the inner diameter of the circular groove 3 to shrink or expand when the sliding rod 52 moves outward. The spiral spring 55 connects the arc-shaped block 54 and the fixed plate 53. It can buffer the squeezing force of the arc-shaped block 54 on the circular groove 3, avoid excessive squeezing and damage to the circular groove 3, and at the same time ensure that the arc-shaped block 54 always fits tightly against the inner wall of the circular groove 3, ensuring the inner diameter adjustment effect and improving work efficiency.
