Description

Technical Field

[0001] This utility model relates to the field of computerized flat knitting machines, and in particular to a detachable roller structure in a flat knitting machine. Background Technology

[0002] With the development of technology, the textile industry has entered the era of automation. Computerized flat knitting machines are a type of knitting machine commonly used in the textile industry, which greatly improves the production efficiency of fabrics. In recent years, the technology of computerized flat knitting machines has gradually matured and formed a set of knitting processes including loop unwinding, yarn padding, yarn feeding, loop closing, loop forming, loop release, loop formation, and pulling. Among them, pulling is the last discharge process after the fabric is completed. In order to ensure that the fabric is evenly discharged, the flat knitting machine must pull the knitted fabric to complete the subsequent knitting. That is, knitting can only proceed smoothly under the state of traction. The roller is the pulling mechanism of the flat knitting machine, which mainly plays the role of pulling the fabric.

[0003] As the rollers rotate, they pull the yarn fabric, causing it to wrap around the rollers. Once the wrapping is complete, workers usually need to manually remove the yarn rolls from the rollers horizontally. However, during the removal process, regularly wound yarn rolls may become tangled and messy, or some tightly wound yarn loops may be difficult to remove, increasing the workload of workers and reducing work efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a detachable roller structure for a flat knitting machine, based on the current state of the technology.

[0022] like Figures 1 to 4As shown, this utility model provides a detachable roller structure for a flat knitting machine, including a roller assembly. The roller assembly includes a roller rod unit and a fixing unit, which are detachably connected. Specifically, the fixing unit is arranged on both sides of the roller rod unit, and the roller rod unit includes at least two rods with a gap 5 between them.

[0023] The existing roller rod is divided into four rods, with a gap 5 between each pair of adjacent rods. Any one of the four rods can be pulled out and removed individually. This is to facilitate the disassembly work after the yarn is wound. The gap 5 allows the rod to move within the yarn roll, making it easier for workers to remove the rod from the yarn roll.

[0024] The roller rod unit includes four rods: a first rod 1, a second rod 2, a third rod 3, and a fourth rod 4. A gap 5 is provided between each pair of adjacent rods. The advantage of providing the gap 5 is to prevent the rods from squeezing and deforming each other, which would cause cracks. Specifically, the outer edge of the rod is arc-shaped, and the cross-section of the rod extends vertically inward from the two ends of the arc. The outer edge of the roller rod unit as a whole is nearly circular. The near-circular shape allows the roller assembly to better wind the yarn fabric when it rotates.

[0025] The fixing unit includes a first fixing plate 6 and a second fixing plate 7 respectively located on both sides of the roller rod unit. The fixing unit is provided with a first connecting hole 8 for connecting with the rod body. Specifically, each end cross section of the rod body is provided with a second connecting hole 9 that cooperates with the first connecting hole 8. The corresponding first connecting hole 8 and second connecting hole 9 are fixedly connected by a connector 10.

[0026] It also includes a limiting unit for balancing the spacing between the rods. The limiting unit includes a lateral limiting piece 11 and a longitudinal limiting piece 12. Specifically, the lateral limiting piece 11 and the longitudinal limiting piece 12 have the same width. The limiting unit is inserted into the gap 5. The lateral limiting piece 11 and the longitudinal limiting piece 12 are only different in placement and insertion orientation, but are actually the same structure. The lateral limiting piece 11 and the longitudinal limiting piece 12 are used to balance the lateral gap 5 and the longitudinal gap 5 between the rods, respectively, so that the spacing between adjacent rods is the same, which makes it easy to align the connecting holes and make it easy to insert and fix the connector 10.

[0027] The limiting unit has a third connecting hole 13 at both ends for connection and fixation. After the limiting unit and the inner sides of the two fixing units are respectively connected and inserted into the gap 5, the third connecting hole 13 and the first connecting hole 8 are fixedly connected by the connector 10.

[0028] The roller rod unit is provided with a positioning unit 14 for limiting the overall width of the winding yarn. The transverse limiting piece 11 and the longitudinal limiting piece 12 are respectively arranged on both sides of the positioning unit 14. Specifically, the positioning unit 14 is provided with a fourth connecting hole 15 that cooperates with the third connecting hole 13. The fourth connecting hole 15 and the third connecting hole 13 are fixedly connected by a connector 10.

[0029] In the computerized flat knitting machine, the first fixing plate 6 and the second fixing plate 7 are detachably connected to the machine body on the side away from the roller rod unit. Since this is not the focus of this utility model, and the structure of the whole machine and the way the fixing unit and the machine body are detachably connected are common and easy-to-think technical means for those skilled in the art, it will not be described in detail.

[0030] The working principle of this utility model is as follows: During disassembly, by pulling the connector 10 out from between the first connecting hole 8 and the second connecting hole 9, the first fixing piece 6 and the second fixing piece 7 can be disengaged from the roller rod unit. After removing the first fixing piece 6 and the second fixing piece 7, any one of the four rods can be pulled out individually, or the roller rod unit can be pulled out as a whole, thus completely detaching the yarn loops wound on the rods. The existing whole roller rod is divided into four rods, with a gap 5 between each pair of adjacent rods. Any one of the four rods can be pulled out and disassembled individually. This is to facilitate the disassembly work after the yarn is wound. The gap 5 allows the rods to move within the yarn roll, making it convenient for workers to remove the rods from the yarn roll.

[0031] The advantages of this invention are as follows: by setting the four roller rods to be detachably connected to the fixing plates on both sides, users can disassemble the four roller rods individually or as a whole by removing the connection between the fixing plates and the roller rod unit. This eliminates the need for workers to remove the yarn by moving the yarn rolls on the roller rods. Compared to other methods, disassembling the roller rods greatly improves work efficiency and prevents the yarn from becoming tangled or messy.
