Description

Technical Field

[0001] This utility model relates to the field of sock knitting machine technology, and in particular to a flipping mechanism and a sock knitting machine thereof. Background Technology

[0002] Currently, sock manufacturing involves the use of sock knitting machines for textile processing. Sock knitting machines can be classified according to needle bed type, needle type, and number of cylinders (beds). Flatbed sock knitting machines have a higher size range and produce flat sock pieces with varying widths to accommodate different foot and leg shapes. These are then sewn together to form seamed socks. Circular knitting machines have a wider size range and produce tubular sock blanks by changing the size of the loops in different sections, using elastic yarn, or knitting the toe and heel to fit the foot shape. The toe of the tubular sock blank is then sealed to create a seamless sock.

[0003] Currently, in the process of knitting socks, a drive mechanism is often used to rotate the flipping bracket, thereby turning the socks over so that they can be further processed.

[0004] The aforementioned flipping mechanism's flipping bracket and motor are mostly connected by connectors, which requires a certain level of installation dimensional accuracy. Furthermore, it is not convenient to adapt and install flipping brackets of different sizes. Therefore, we propose a flipping mechanism and its sock knitting machine. Utility Model Content

[0005] The purpose of this utility model is to provide a flipping mechanism and a sock knitting machine thereof. By setting a connecting mechanism, it is convenient to quickly insert the pressure block between the clamping blocks, so that the clamping blocks can hold the pressure block using the elastic component, and the pressure block can be further fixed by the compression sleeve, thereby facilitating the quick assembly of flipping brackets of different sizes.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] In a first aspect, this utility model provides a flipping mechanism, including a rotating shaft and a flipping bracket located above the rotating shaft, wherein a connecting mechanism is provided between the rotating shaft and the flipping bracket, the connecting mechanism comprising:

[0008] A connecting column is fixedly connected to the end of the rotating shaft, and a connecting circular plate is fixedly connected to one end of the connecting column;

[0009] Clamping blocks are rotatably provided on both sides of the top of the connecting circular plate, and an elastic component is provided between the connecting circular plate and the clamping blocks;

[0010] A compression sleeve, which is threadedly connected to the middle of the connecting column;

[0011] The pressure block is fixedly connected to the bottom of the flipping bracket, and the clamping block holds the pressure block by an elastic component.

[0012] Preferably, the elastic component includes:

[0013] Fixed columns are provided on both sides of the top of the connecting circular plate. Each fixed column has a protrusion fixedly connected to its two end faces. The fixed column is fixedly connected to the outer surface of the connecting circular plate through the corresponding two protrusions.

[0014] Two connecting sleeves are fitted at both ends of the fixing column, and each pair of connecting sleeves is fixedly connected to the outer surface of the corresponding clamping block.

[0015] A torsion spring, wherein the torsion spring is sleeved in the middle of the fixed column.

[0016] Preferably, the pressure block includes a rectangular block fixedly connected to the bottom of the flipping bracket and a triangular block connected to the bottom of the rectangular block, and the rectangular block and the triangular block are integrally formed.

[0017] Preferably, the pressure block has grooves on both sides, and the width of the grooves is adapted to the width of the clamping block.

[0018] Preferably, a ramp is provided on one side of the end of the clamping block, and a compression pad is fixedly connected to the end face of the clamping block.

[0019] Secondly, this utility model provides a sock knitting machine, including a flipping mechanism as described above.

[0020] The technical effects and advantages of this utility model are as follows:

[0021] The flip bracket moves the pressure block downward, which pushes open the clamping block and causes the clamping block to deflect. At the same time, it squeezes the elastic component until the clamping block initially fixes the pressure block using the elastic component. Then, the compression sleeve is rotated to further screw the compression sleeve and the connecting column until the compression sleeve squeezes the side of the clamping block, thereby making the clamping block stably hold the pressure block. This allows the flip bracket to be smoothly connected to the rotating shaft. This design does not require high installation accuracy, is firmly installed, and is relatively simple to install. It can also be adapted to flip brackets of different sizes. Attached Figure Description

[0028] This utility model provides, for example Figure 1-4 The image shows a flipping mechanism. Example

[0029] The device includes a rotating shaft 1 and a flipping bracket 2 located above the rotating shaft 1. A connecting mechanism is provided between the rotating shaft 1 and the flipping bracket 2. The connecting mechanism includes: a connecting column 3, which is fixedly connected to the end of the rotating shaft 1, and a connecting circular plate 4 is fixedly connected to one end of the connecting column 3; clamping blocks 6, which are rotatably mounted on both sides of the top of the connecting circular plate 4, and an elastic component 5 is provided between the connecting circular plate 4 and the clamping blocks 6; a compression sleeve 7, which is threadedly connected to the middle of the connecting column 3; and a pressure block 8, which is fixedly connected to the bottom of the flipping bracket 2, and the clamping block 6 clamps the pressure block 8 through the elastic component 5. The flipping bracket 2 is aligned with the connecting mechanism. The mechanism is inserted, and the pressure block 8 is moved down by the flip bracket 2. The pressure block 8 pushes open the clamping block 6 and causes the clamping block 6 to deflect. At the same time, it squeezes the elastic component 5 until the clamping block 6 initially fixes the pressure block 8 by the elastic component 5. Then, the compression sleeve 7 is rotated so that the compression sleeve 7 and the connecting column 3 are further screwed together until the compression sleeve 7 squeezes the side of the clamping block 6, so that the clamping block 6 stably clamps the pressure block 8, thereby smoothly connecting the flip bracket 2 and the rotating shaft 1. This design does not require high installation accuracy, is firmly installed, and is relatively simple to install. It can also be adapted to flip brackets 2 of different sizes.

[0030] Furthermore, the elastic component 5 includes: a fixing post 501, with fixing posts 501 provided on both sides of the top of the connecting circular plate 4, each fixing post 501 having a protrusion fixedly connected to both end faces, and the fixing post 501 being fixedly connected to the outer surface of the connecting circular plate 4 through the corresponding two protrusions; a connecting sleeve 502, with two connecting sleeves 502 sleeved on both ends of the fixing post 501, and each pair of connecting sleeves 502 being fixedly connected to the outer surface of the corresponding clamping block 6; and a torsion spring 503, with the torsion spring 503 sleeved in the middle of the fixing post 501; by the pressure block 8 pressing the clamping block 6, the clamping block 6 causes the connecting sleeve 502 to rotate along the fixing post 501, thereby pressing the torsion spring 503, and by utilizing the deformed torsion spring 503, the clamping block 6 initially clamps and fixes the pressure block 8, thus facilitating the further fixation of the pressure block 8 in the later stage.

[0031] Furthermore, the pressure block 8 includes a rectangular block 801 fixedly connected to the bottom of the flip bracket 2 and a triangular block 802 connected to the bottom of the rectangular block 801, and the rectangular block 801 and the triangular block 802 are integrally formed; the design of the triangular block 802 is to facilitate the quick insertion of the pressure block 8 and push open the two clamping blocks 6, while the rectangular block 801 is to facilitate the stable contact between the ends of the clamping blocks 6 and the pressure block 8, thereby achieving a good fixing effect.

[0032] Furthermore, grooves 11 are provided on both sides of the pressure block 8, and the width of the groove 11 is adapted to the width of the clamping block 6; this facilitates the clamping block 6 to slide along the groove 11, thereby clamping the pressure block 8, and also makes it easier for the clamping block 6 to limit the position of the pressure block 8, thereby preventing the pressure block 8 from easily shaking. Example

[0033] Example 2 further discloses that, based on Example 1, a ramp 9 is provided on one side of the end of the clamping block 6, and a compression pad 10 is fixedly connected to the end face of the clamping block 6; by providing the ramp 9 on the clamping block 6, it is easy for the triangular block 802 to be quickly and accurately inserted between the two clamping blocks 6, thereby making it easy to push the two clamping blocks 6 open; the rubber compression pad 10 makes it easy for the compression sleeve 7 to compress the clamping block 6, so that the clamping block 6 can stably clamp and fix the pressure block 8.

[0034] The rotating shaft 1 can be rotated using existing drive mechanisms, such as a motor and a reducer.

[0035] In another embodiment, a sock knitting machine is also provided, including the aforementioned flipping mechanism.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
