Technical Field
[0001] This utility model relates to the field of computerized flat knitting machine technology, specifically to a structurally stable head component of a computerized flat knitting machine. Background Technology
[0002] A computerized flat knitting machine is a double-needle plate-latch weft knitting machine. Its cam mechanism is like a set of planar cams. The needle feet can enter the grooves of the cams. Moving the cams forces the needles to make regular up-and-down movements within the needle grooves of the needle plate. Through the actions of the needle hook and the needle latch, the yarn can be knitted into fabric. During the upward movement of the needle, the loops gradually exit the needle hook, the needle latch opens, and the needle latch exits and hangs on the needle bar. During the downward movement of the needle, the needle hook catches the newly placed yarn and pulls it to bend into a loop. At the same time, the existing loops exit the needle hook, and the new loops pass through the old loops, connecting with them in series. Numerous loops knitted together form the fabric.
[0003] According to Chinese Patent Publication No. CN217298190U, a structurally stable computer-controlled flat knitting machine head component includes a bridge, and a color-changing bracket and a yarn-changing frame are fixedly installed inside the bridge. The yarn-changing frame is equipped with a yarn changer.
[0004] The computerized flat knitting machine head assembly described in this announcement strengthens the stability of the connection between the overhead bridge and the aluminum cover by fixing it to the four corners of the bridge with four connecting brackets. Because the machine head and the bridge arm of the overhead bridge need to move continuously and frequently during operation, especially in high-speed, high-load production environments, these components face a significant risk of wear. Therefore, regular maintenance or replacement of the bridge arm connecting the overhead bridge and the aluminum cover is required. The connecting brackets in this announcement serve the function of the bridge arm, and since the connecting brackets and the overhead bridge are a fixed, integrated structure, replacing or maintaining the bridge arm requires replacing the entire overhead bridge assembly, increasing maintenance costs. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a computerized flat knitting machine head component with a stable structure, which has advantages such as easy maintenance or replacement of the bridge arm.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a structurally stable computer knitting flat knitting machine head component, including a bridge and a bridge arm, wherein an installation structure is provided between the bridge and the bridge arm.
[0007] The installation structure includes two fixed covers, which are respectively fixed to the front and rear side walls of the overpass. A bidirectional threaded rod is rotatably connected inside each fixed cover. Threaded sleeves are threaded to both the left and right sides of the bidirectional threaded rod. A driven bevel gear is fixed to the outside of the bidirectional threaded rod near its center. A rotating rod passes through the top of the fixed cover, and a driving bevel gear is fixedly connected to the bottom of the rotating rod. The driving bevel gear meshes with the driven bevel gear. A rotating block is fixedly connected to the top of the rotating rod. A locking block is fixedly connected to the side of the threaded sleeve away from the driven bevel gear. Embedding grooves are provided on both the front and rear side walls of the overpass. The bridge arm is engaged inside the embedding groove. A connecting block is fixed to the side of the bridge arm away from the overpass. One end of the locking block passes through the fixed cover and is inserted into the connecting block.
[0008] The top of the fixed cover is provided with a limiting component for locking the rotating block.
[0009] Furthermore, the limiting member includes an insert rod, which is slidably connected inside a groove formed on the top of the fixed cover. A slide rod is fixed inside the groove, and the insert rod is slidably connected outside the slide rod. A spring is sleeved on the outside of the slide rod.
[0010] Furthermore, the side wall of the rotating block is provided with multiple slots that are equidistantly distributed around it, and the end of the insert rod away from the slide rod is inserted into the inside of the slot.
[0011] Furthermore, a circular groove is provided on the top of the rotating block, and a handle is fixed inside the circular groove.
[0012] Furthermore, a guide slider is fixed to the top of the threaded sleeve, and guide grooves are provided on both the left and right sides of the inner top wall of the fixed cover, with the guide slider slidably connected inside the guide grooves.
[0013] Furthermore, a mounting base is fixedly connected to the side of the bridge arm away from the overpass, and an aluminum cover for the machine head can be detachably installed on the side of the mounting base away from the bridge arm.
[0014] Furthermore, there are two aluminum covers for the machine head, and the four mounting bases are respectively installed at the corners of the two aluminum covers for the machine head.
[0015] Furthermore, a limiting block is fixed to the side wall of the bridge arm, and a limiting groove is opened on the side wall of the overpass located on the inner wall of the embedding groove, and the limiting block is engaged inside the embedding groove.
[0016] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0017] This stable computer-controlled flat knitting machine head component, through its installation structure, allows for easy maintenance of the bridge arm. By rotating the rotating block, the rotating rod can be driven to rotate, which in turn drives the driven bevel gear to rotate, thereby rotating the bidirectional threaded rod. This causes the two threaded sleeves to move relative to each other, thus removing the locking block from the connecting block. After that, the bridge arm can be removed from the embedded groove, facilitating the maintenance or replacement of damaged bridge arms. Attached Figure Description

[0023] 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.
[0024] Please see Figures 1 to 4 In this embodiment, a stable computer knitting flat knitting machine head component includes a bridge 1 and a bridge arm 4, with an installation structure provided between the bridge 1 and the bridge arm 4.
[0025] The installation structure includes two fixed covers 6, which are respectively fixed to the front and rear side walls of the overpass 1. A double-threaded rod 11 is rotatably connected inside each fixed cover 6. Threaded sleeves 13 are threaded to the left and right sides of the double-threaded rod 11. A driven bevel gear 12 is fixed to the outside of the double-threaded rod 11 near its center. A rotating rod 15 passes through the top of the fixed cover 6. A driving bevel gear 16 is fixedly connected to the bottom of the rotating rod 15. The driving bevel gear 16 meshes with the driven bevel gear 12. A rotating block 17 is fixedly connected to the top of 5. A locking block 14 is fixedly connected to the side of the threaded sleeve 13 away from the driven bevel gear 12. An embedding groove 8 is provided on both the front and rear side walls of the overpass 1. The bridge arm 4 is snapped into the inside of the embedding groove 8. A connecting block 7 is fixed on the side of the bridge arm 4 away from the overpass 1. One end of the locking block 14 passes through the fixed cover 6 and is inserted into the inside of the connecting block 7. A limit block 9 is fixed on the side wall of the bridge arm 4. A limit groove 10 is provided on the side wall of the overpass 1 located on the inner wall of the embedding groove 8. The limit block 9 is snapped into the inside of the embedding groove 8.
[0026] By setting up the installation structure, when it is necessary to maintain the bridge arm 4, the rotating block 17 is rotated to drive the rotating rod 15 to rotate, which will cause the driving bevel gear 16 to rotate and drive the driven bevel gear 12 to rotate, thereby causing the bidirectional threaded rod 11 to rotate, thereby causing the two threaded sleeves 13 to move relative to each other, thereby removing the locking block 14 from the connecting block 7. Then the bridge arm 4 can be removed from the embedded groove 8, which facilitates the maintenance or replacement of the damaged bridge arm 4.
[0027] The rotating rod 15 is rotatably connected to the fixed cover 6, and a limiting rotating ring is fixed to the outside of the rotating rod 15 at the top and inner wall of the fixed cover 6.
[0028] The top of the fixed cover 6 is provided with a limiting member for locking the rotating block 17. The limiting member includes a rod 18, which is slidably connected inside a groove 19 opened on the top of the fixed cover 6. A slide rod 20 is fixed inside the groove 19. The rod 18 is slidably connected to the outside of the slide rod 20. A spring 21 is sleeved on the outside of the slide rod 20. The side wall of the rotating block 17 is provided with multiple slots 22 that are equidistantly distributed around it. The end of the rod 18 away from the slide rod 20 is inserted into the inside of the slot 22. The top of the rotating block 17 is provided with a circular groove, and a handle is fixed inside the circular groove.
[0029] It should be noted that the spring 21 itself can make the insert rod 18 insert into the corresponding slot 22, thereby limiting the rotating block 17 and preventing the rotating block 17 from rotating easily. When it is necessary to rotate the rotating block 17, the insert rod 18 can be pulled out from the slot 22.
[0030] Among them, the top of the threaded sleeve 13 is fixed with a guide slider, and the left and right sides of the inner top wall of the fixed cover 6 are provided with guide grooves, and the guide slider is slidably connected inside the guide groove.
[0031] The sliding connection between the guide slider and the guide groove restricts the threaded sleeve 13, so that the threaded sleeve 13 can only move horizontally when the bidirectional threaded rod 11 rotates.
[0032] Please see Figure 1 A mounting base 3 is fixedly connected to the side of the bridge arm 4 away from the overpass 1. The mounting base 3 is detachably mounted on the side away from the bridge arm 4. There are two machine head aluminum covers 2. The four mounting bases 3 are respectively installed at the corners of the two machine head aluminum covers 2.
[0033] It should be noted that by connecting the bridge arms 4 at the four corners of the overpass 1 to the corners of the two machine head aluminum covers 2, the stability of the connection between the machine head aluminum cover 2 and the overpass 1 can be increased. The crossbar 5 increases the stability of the connection between the bridge arms 4 on both sides, ensuring the stability of the machine head component.
[0034] The working principle of the above embodiment is as follows: During installation, one side of the bridge arm 4 is first inserted into the embedding groove 8. The limiting block 9 prevents the embedding groove 8 from slipping. Then, rotating the rotating block 17 drives the rotating rod 15 to rotate, which in turn causes the driving bevel gear 16 to rotate, driving the driven bevel gear 12 to rotate. This causes the bidirectional threaded rod 11 to rotate. Under the limiting effect of the sliding connection between the guide slider and the guide groove, the two threaded sleeves 13 move in opposite directions, and the locking block 14 is inserted into the connecting block 7, thereby locking the bridge arm 4. The bridge arm 4 and the overpass 1 can be connected and fixed together. Conversely, when the bridge arm 4 needs to be maintained, the rotating block 17 is rotated in the opposite direction, so that the two threaded sleeves 13 can be moved relative to each other, and the locking block 14 can be moved out of the connecting block 7. This makes it easy to remove the bridge arm 4 from the embedded groove 8, which is convenient for maintenance or replacement of the damaged bridge arm 4. The bridge arms 4 located at the four corners of the overpass 1 are connected to the corners of the two machine head aluminum covers 2, which can increase the stability of the connection between the machine head aluminum cover 2 and the overpass 1. The crossbar 5 increases the stability of the connection between the bridge arms 4 on both sides.
