Description

Technical Field

[0001] The utility model relates to the technical field of circular knitting machines, in particular to a circular knitting machine with convenient yarn supply. Background Art

[0002] Circular knitting machines, also known as circular weft knitting machines (or circular weft knitting machines), have experienced rapid growth due to their multiple loop-forming systems (referred to in the industry as the number of yarn feed paths or loop-forming paths, or simply paths), high speed, high output, fast pattern changes, high fabric quality, minimal process steps, and strong product adaptability.

[0003] A Chinese utility model patent with publication number CN219137077U discloses a circular knitting machine with convenient yarn supply, including a yarn frame and a circular knitting machine body. A plurality of wire coil support frames are arranged at intervals on the wire frame. The wire coil support frame includes a fixing portion fixedly mounted on the wire frame, a slide groove is provided from the top downwardly on the fixing portion, and an annular groove is provided at the tail end of the slide groove. The inner cavity of the wire bobbin is a cylinder with the same taper as the fixing portion. A raised limiting portion is provided at the bottom of the inner cavity of the wire bobbin. When the wire coil is mounted on the wire coil support frame, the raised limiting portion enters along the slide groove. When reaching the annular groove, the wire coil is rotated so that the raised limiting portion is limited in the annular groove.

[0004] Regarding the above-mentioned related technologies, the inventor believes that the following defects exist: when the yarn bobbin of the above-mentioned device is installed, the raised limiting part slides in the slide groove into the annular groove. When it needs to be removed, the raised limiting part needs to be slid from the annular groove into the slide groove. However, the position of the raised limiting part cannot be seen from the outside, so it is inconvenient to remove it; and after the current batch of knitting is completed, when it needs to be quickly replaced with the next batch, the unnecessary yarn bobbins need to be removed one by one, which is inefficient. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a circular knitting machine with convenient yarn supply.

[0006] The above-mentioned technical objectives of the present utility model are achieved through the following technical solutions: a circular knitting machine for convenient yarn supply, comprising a yarn frame, a circular knitting machine body, and a wire reel, wherein the wire reel comprises a wire group and a wire spool, the yarn frame is rotatably provided with a plurality of vertically spaced rotating shafts, the rotating shaft is horizontally spaced with a plurality of connecting columns, the end of the connecting column is provided with a wire reel fixing column, the wire reel fixing column is in the shape of a conical column, and a first limiting groove and a second limiting groove are provided on the wire reel fixing column along the length direction of the connecting column, and a connecting groove is connected between the first limiting groove and the second limiting groove adjacent to one end of the connecting column, a convex column is provided in the wire spool, a limiting assembly is provided in the connecting groove, a limiting plate is provided at the bottom of the second limiting groove for vertical sliding, an adjusting assembly for adjusting the position of the limiting plate is provided on the yarn frame, and a rotating assembly for controlling the rotation of the rotating shaft is provided at the end of the rotating shaft.

[0007] By adopting the above technical solution, a rotating shaft, a wire reel fixing column, a limiting assembly, an adjusting assembly, and a rotating assembly are set. When installing the wire reel on the wire reel fixing column, the boss of the wire reel is first aligned with the first limiting groove and pushed inward so that the boss enters the connecting groove, and then the wire reel is rotated so that the boss reaches the second limiting groove. At this time, the boss is located between the limiting assembly and the limiting plate, so that the position of the boss is fixed, thereby fixing the wire reel; when disassembling a single one, the wire reel is pushed to push the limiting assembly away, and then the boss is rotated and then slid so that the boss passes through the connecting groove and enters the first limiting groove, the first limiting groove, the second limiting groove Located at both ends of the connecting groove, when the staff rotates the thread spool to the left or right and cannot rotate, they will know that it is located at the first limit slot or the second limit slot, which is convenient for operation; after the current batch of knitting is completed, when it needs to be quickly replaced with the next batch, a collecting frame is placed on the lower side of the creel, and the rotation of the rotating shaft is controlled by the rotating component to make the thread roll fixing column tilt downward. At this time, the adjusting component adjusts the position of the limit plate so that the limit plate loses the restriction on the convex column. At this time, the thread roll slides from the thread roll fixing column under the action of its own gravity and falls into the collecting frame, thereby realizing the rapid unloading of the thread roll on the creel with high efficiency.

[0008] Furthermore, two guide holes are provided on the side wall of the connecting groove adjacent to the connecting column toward the side wall of the wire coil fixing column adjacent to the connecting column, and the limiting assembly includes a guide rod slidably arranged in the guide hole, and the two guide rods are located in the connecting groove and have a baffle commonly provided at one end, and the guide rod is located between the baffle and the side wall of the connecting groove adjacent to the connecting column and is sleeved with a first compression spring.

When the wire reel is installed on the wire reel fixing column, the protrusion of the wire spool is aligned with the first limit groove and pushed inward. After the protrusion contacts the baffle, it continues to push the wire spool, causing the baffle and the guide rod to slide and the first compression spring to be compressed. Then the wire spool is rotated so that the protrusion reaches the end portion of the connecting groove that is connected to the second limit groove, and the wire spool is released. The first compression spring pushes the guide rod and the baffle to reset under the action of elastic force, so that the protrusion is pushed into the second limit groove, and the protrusion is fixed between the baffle and the limit plate; when a single wire spool needs to be disassembled, the wire spool is pushed so that the protrusion pushes the baffle, the guide rod to slide, and the first compression spring is compressed. Then the wire spool is rotated so that the protrusion reaches the end portion of the connecting groove that is connected to the first limit groove, and then the wire spool slides out.

[0010] Furthermore, the adjusting assembly includes a rotating shaft rotatably arranged on the yarn rack and correspondingly arranged above the rotating shaft, a square hole is provided on the wire reel fixing column, a square rod connected to the rotating shaft is slidably provided in the square hole, and the upper edge of the square rod at one end of the square hole is chamfered, and a first sliding hole is vertically provided on the wire reel fixing column, and a receiving slot is provided at the bottom of the first limiting groove toward the wire reel fixing column, and a second sliding hole connected to the square hole is provided at the bottom of the receiving groove, and the limiting plate is slidably connected to the second sliding hole and the first sliding hole, and a baffle is horizontally provided on the plate body of the limiting plate located in the receiving groove, and a second compression spring is provided in the receiving groove between the top of the baffle and the groove wall at the top of the receiving groove.

Under the action of the second compression spring, the baffle and the limit plate are pushed to move under the elastic force of the second compression spring, so that the upper end of the limit plate is completely located in the first sliding hole and the lower end is located in the square hole. The obstruction in the second limiting groove is lost, and the protruding post can slide out of the second limiting groove; when the rotating shaft is rotated to drive the wire coil fixing post to return to its original position, the square rod slides and returns to its original position. During the sliding process, the chamfer on it contacts the lower end of the limit plate in the square hole, pushing the limit plate upward, causing the limit plate to return to its original position and the second compression spring to be compressed.

[0012] Furthermore, the rotating assembly includes a first connecting plate arranged at one end of the rotating shaft, several of the first connecting plates are arranged in parallel, the first connecting plate is rotatably arranged with a first connecting shaft at one end away from the rotating shaft, the first connecting shaft is arranged parallel to the rotating shaft, and several of the first connecting shaft ends are jointly provided with a first movable plate, the first movable plate is rotatably connected to several first connecting shafts, one of the first connecting plates is provided with an extension plate at one end away from the rotating shaft, a handle is provided on the extension plate at one end away from the first connecting plate, and a fixing unit for fixing the extension plate is provided on the yarn rack.

The handle is moved to move the extension plate, which drives the first connecting plate connected to it to rotate, thereby driving the first movable plate to move, so that the remaining first connecting plates rotate synchronously, thereby making several rotating shafts rotate synchronously. When the rotating shaft needs to be rotated, the position of the extension plate is fixed by the fixing unit.

[0014] Furthermore, the fixing unit includes a threaded hole horizontally opened on the creel, and a through hole is horizontally opened on the extension plate. The bolt passes through the through hole and is screwed into the threaded hole to fix the extension plate.

[0015] By adopting the above technical solution, threaded holes and through holes are provided, and bolts pass through the through holes and are screwed into the threaded holes to fix the extension plates.

[0016] Furthermore, the head of the bolt is provided with a screw cap.

[0017] By adopting the above technical solution, a screw cap is provided on the head of the bolt, which makes it easier for workers to rotate the bolt.

[0018] Furthermore, a second connecting plate is provided at one end of the rotating shaft away from the second connecting plate, and several of the second connecting plates are arranged in parallel. A second connecting shaft is rotatably provided at one end of the second connecting plate away from the rotating shaft, and the second connecting shaft is arranged parallel to the rotating shaft. A second movable plate is commonly provided at the ends of several of the second connecting shafts, and the second movable plate is rotatably connected to several second connecting shafts.

When installing the wire coil on the wire coil fixing column, first align the protrusion of the wire drum with the first limiting groove and push it inward so that the protrusion enters the connecting groove, and then rotate the wire drum so that the protrusion reaches the second limiting groove. At this time, the protrusion is located between the limiting assembly and the limiting plate, so that the position of the protrusion is fixed, thereby fixing the wire coil; when disassembling a single wire coil, push the wire coil to push the limiting assembly away, and then rotate the protrusion and slide it so that the protrusion passes through the connecting groove and enters the first limiting groove. The first limiting groove and the second limiting groove are located at When the thread roll is unloaded from the creel, the thread roll is unloaded from the creel and the thread is then unloaded into the creel, which is very convenient for operation.

[0033] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; it is obvious that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0034] like Figure 1-9As shown, the present embodiment discloses a circular knitting machine for convenient yarn supply, comprising a creel 10, a circular knitting machine body 20, and a bobbin 30. The bobbin 30 includes a yarn assembly 31 and a bobbin 32. The creel 10 is rotatably provided with a plurality of vertically spaced rotating shafts 40. The rotating shafts 40 are horizontally spaced with a plurality of connecting posts 41, the length of which is perpendicular to the length of the rotating shafts 40. A bobbin fixing post 42 is provided at the end of the connecting post 41. The bobbin fixing post 42 is in the shape of a tapered cylinder. The bobbin fixing post 42 is provided with a first limiting groove 43 and a second limiting groove 44 along the length of the connecting post 41. The first limiting groove 43 and the second limiting groove 44 are arranged circumferentially. A connecting groove 45 is connected between the first limiting groove 43 and the second limiting groove 44 near one end of the connecting column 41, a protruding column 33 is provided in the bobbin 32, a limiting component 50 is provided in the connecting groove 45, a limiting plate 46 is provided for vertical sliding at the bottom of the second limiting groove 44, an adjusting component 60 for adjusting the position of the limiting plate 46 is provided on the yarn rack 10, and a rotating component 70 for controlling the rotation of the rotating shaft 40 is provided at the end of the rotating shaft 40.

[0035] When installing the wire reel 30 on the wire reel fixing post 42, first align the protrusion 33 of the wire reel 32 with the first limiting groove 43 and push it inward, so that the protrusion 33 enters the connecting groove 45, and then rotate the wire reel 32 so that the protrusion 33 reaches the second limiting groove 44. At this time, the protrusion 33 is located between the limiting assembly 50 and the limiting plate 46, so that the position of the protrusion 33 is fixed, thereby fixing the wire reel 30; when disassembling individually, push the wire reel 30, push the limiting assembly 50 away, and then rotate the protrusion 33 and slide it so that the protrusion 33 passes through the connecting groove 45 and enters the first limiting groove 43. The first limiting groove 43 and the second limiting groove 44 are located at both ends of the connecting groove 45. When the staff turns the spool 32 and cannot turn it to the left or right, it can be known that it is located at the first limit groove 43 or the second limit groove 44, which is convenient for operation. After the current batch of knitting is completed and it needs to be quickly replaced with the next batch, a collection frame is placed on the lower side of the yarn rack 10, and the rotation shaft 40 is controlled by the rotation component 70 to rotate so that the wire roll fixing column 42 tilts downward. At this time, the adjustment component 60 adjusts the position of the limit plate 46 so that the limit plate 46 loses the restriction on the protrusion 33. At this time, the wire roll 30 slides from the wire roll fixing column 42 under the action of its own gravity and falls into the collection frame, thereby realizing the rapid removal of the wire roll 30 on the yarn rack 10 with high efficiency.

[0036] Specifically, two guide holes are formed in the wall of the connecting groove 45 on the side adjacent to the connecting column 41, facing the side wall of the wire coil fixing column 42 on the side adjacent to the connecting column 41. The limiting assembly 50 includes a guide rod 51 slidably disposed in the guide holes. The two guide rods 51 are located in the connecting groove 45 and are jointly provided with a baffle 52 at one end, so that the baffle 52 and the guide rods 51 slide synchronously. A first compression spring 53 is sleeved on the guide rod 51, which is located between the baffle 52 and the wall of the connecting groove 45 on the side adjacent to the connecting column 41. The first compression spring 53 is compressed, and then the wire drum 32 is rotated so that the boss 33 reaches the end of the connecting groove 45 that is connected to the second limiting groove 43, and the wire drum 32 is released. The first compression spring 53 pushes the guide rod 51 and the baffle 52 to return to its original position under the action of the elastic force, so that the boss 33 is pushed into the second limiting groove 44, and the boss 33 is fixed between the baffle 52 and the limiting plate 46; when a single wire drum 32 needs to be disassembled, the wire drum 32 is pushed so that the boss 33 pushes the baffle 52 and the guide rod 51 to slide, and the first compression spring 53 is compressed. Then the wire drum 32 is rotated so that the boss 33 reaches the end of the connecting groove 45 that is connected to the first limiting groove 43, and then the wire drum 32 slides out.

[0037] During installation, the adjustment assembly 60 includes a rotating shaft 61 rotatably mounted on the creel 10 and correspondingly arranged above the rotating shaft 40. The rotating shaft 61 is parallel to the rotating shaft 40. A square hole 62 is defined in the wire coil fixing post 42. A square rod 63 connected to the rotating shaft 61 is slidably disposed within the square hole 62. When the rotating shaft 40 rotates and drives the wire coil fixing post 42, the square rod 63 slides within the square hole 62 because one end of the square rod 63 is connected to the rotating shaft 61. A first sliding hole 64 is vertically defined in the wire coil fixing post 42. A receiving slot 65 is defined at the bottom of the first limiting groove 43, extending into the wire coil fixing post 42. A second sliding hole 66 is defined at the bottom of the receiving groove 65, communicating with the square hole 62. The second sliding hole 66 corresponds to the first sliding hole 64. A limiting plate 46 is slidably connected to the second sliding hole 66 and the first sliding hole 64. A stopper 67 is horizontally disposed on the limiting plate 46, located within the receiving slot 65. The limiting plate 46 is perpendicular to the stopper 67. A second compression spring 68 is provided in the receiving groove 65 between the top of the baffle 67 and the top wall of the receiving groove 65. Under normal circumstances, the square rod 63 is placed in the square hole 62, and the lower end of the limit plate 46 abuts against the top of the square rod 63, so that the position of the limit plate 46 is fixed. When the rotating shaft 40 rotates and the wire coil fixing column 42 tilts downward, the rotating shaft 61 rotates, and the square rod 63 slides, so that the top of the square rod 63 is separated from the lower end of the limit plate 46. Under the action of the elastic force of the second compression spring 68, the baffle 52 and the limit plate 46 are pushed to move, so that the upper end of the limit plate 46 is completely located in the first sliding hole 64 and the lower end is located. Located in the square hole 62, the second limit groove 44 loses its obstruction, and the protrusion 33 can slide out of the second limit groove 44; when the rotating shaft 40 is rotated to drive the wire roll fixing column 42 to reset, the square rod 63 slides and resets, and the upper edge of the square rod 63 at one end of the square hole 62 is provided with a chamfer. During the sliding process, the chamfer on it contacts the lower end of the limit plate 46 located in the square hole 62, pushing the limit plate 46 upward, so that the limit plate 46 is reset, and the second compression spring 68 is compressed.

[0038] In specific configuration, the rotating assembly 70 includes a first connecting plate 71 disposed at one end of the rotating shaft 40. Several first connecting plates 71 are arranged in parallel. A first connecting shaft 72 is rotatably disposed at the end of the first connecting plate 71 away from the rotating shaft 40. The first connecting shaft 72 is arranged parallel to the rotating shaft 40. A first movable plate 73 is commonly disposed at the ends of the several first connecting shafts 72. The first movable plate 73 is rotatably connected to the several first connecting shafts 72. When one of the first connecting plates 71 rotates, it drives the first movable plate 73 to move, causing the remaining first connecting plates 71 to rotate synchronously, thereby causing the several rotating shafts 40 to rotate synchronously. An extension plate 74 is disposed at the end of one of the first connecting plates 71 away from the rotating shaft 40. A handle 75 is disposed at the end of the extension plate 74 away from the first connecting plate 71. Moving the handle 75 causes the extension plate 74 to move, driving the first connecting plate 71 connected thereto to rotate. A second connecting plate 90 is provided at one end of the rotating shaft 40 away from the second connecting plate 90, and several second connecting plates 90 are arranged in parallel. A second connecting shaft 91 is rotatably provided at one end of the second connecting plate 90 away from the rotating shaft 40. The second connecting shaft 91 is arranged in parallel with the rotating shaft 40. A second movable plate 92 is commonly provided at the ends of several second connecting shafts 91. The second movable plate 92 is rotatably connected to several second connecting shafts 91. When one of the rotating shafts 40 rotates, it drives the second connecting plate 90 to move, thereby making several second connecting plates 90 move synchronously, ensuring the stability of the rotation of several rotating shafts 40

[0039] The creel 10 is provided with a fixing unit 80 for securing the extension plate 74. Fixing unit 80 includes a threaded hole 81 horizontally defined in the creel 10. A through hole 82 is defined horizontally in the extension plate 74. A bolt 83 passes through through hole 82 and screws into threaded hole 81 to secure the extension plate 74. The head of bolt 83 is provided with a screw cap 84.

[0040] The operating principle of a circular knitting machine for convenient yarn feeding in this embodiment is as follows: when installing the wire reel 30 on the wire reel fixing post 42, first align the protrusion 33 of the wire drum 32 with the first limiting groove 43 and push it inward. After the protrusion 33 contacts the baffle 52, the wire drum 32 is continuously pushed, so that the baffle 52 and the guide rod 51 slide and the first compression spring 53 is compressed. Then, the wire drum 32 is rotated so that the protrusion 33 reaches the end portion where the connecting groove 45 is connected to the second limiting groove 44, and the wire drum 32 is relaxed. The first compression spring 53 is in the elastic force. The guide rod 51 is pushed down and the baffle 52 is reset, so that the boss 33 is pushed into the second limiting groove 44, and the boss 33 is located between the baffle 52 and the limiting plate 46 and is fixed, so that the thread spool 32 is fixed; when a single thread spool 32 needs to be disassembled, the thread spool 32 is pushed so that the boss 33 pushes the baffle 52, the guide rod 51 slides, and the first compression spring 53 is compressed. Then the thread spool 32 is rotated so that the boss 33 reaches the end of the connecting groove 45 that is connected to the first limiting groove 43, and then the thread spool 32 slides out; the current batch of needles After weaving is finished and it is necessary to quickly change to the next batch, a collecting frame is placed on the lower side of the creel 10, and the screw cap 84 is turned to drive the bolt 83 to rotate, so that the bolt 83 leaves the threaded hole 81, and then the handle 75 is moved to move the extension plate 74, which drives the first connecting plate 71 connected thereto to rotate, thereby driving the first movable plate 73 to move, so that the other first connecting plates 71 rotate synchronously, thereby making the several rotating shafts 40 rotate synchronously, so that the wire coil fixing column 42 tilts downward, and at this time, the rotating shaft 61 rotates, and the square The shaped rod 63 slides, so that the top of the square rod 63 is separated from the lower end of the limit plate 46. The second compression spring 68 pushes the baffle 52 and the limit plate 46 to move, so that the upper end of the limit plate 46 is completely located in the first sliding hole 64 and the lower end is located in the square hole 62. The second limit groove 44 loses its obstruction, and the protrusion 33 can slide out of the second limit groove 44. At this time, the wire roll 30 slides off the wire roll fixing column 42 under the action of its own gravity and falls into the collection frame, thereby realizing the rapid unloading of the wire roll 30 on the yarn rack 10 with high efficiency.
