Description

Technical Field

[0001] This utility model relates to the field of circular knitting machine technology, specifically to a micro-adjustment structure for the edges and corners of a large circular knitting machine. Background Technology

[0002] Circular knitting machines, also known as circular weft knitting machines (or circular weft knitting machines), are characterized by their multiple loop-forming systems, high speed, high output, rapid pattern changes, good fabric quality, fewer processes, and strong product adaptability. Circular knitting machines consist of corner blocks and corners. During the weaving process, to achieve the ideal fabric surface effect, the position of the corners needs to be finely adjusted. However, most existing corners and corner blocks are fixedly connected and cannot be flexibly adjusted. Some machines use a method of opening oblong holes in the corner blocks and passing fixing bolts through these holes to connect with the corners, thus achieving corner adjustment. However, this method requires loosening the fixing bolts, moving the corner, and then tightening the fixing bolts again, making the operation relatively cumbersome and inconvenient in overall use.

[0003] In view of this, the applicant has conducted in-depth research on the above-mentioned issues, which led to this case. Utility Model Content

[0004] The purpose of this invention is to provide a fine-tuning structure for the edges and corners of a large circular knitting machine, which makes the adjustment process relatively convenient.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A fine-tuning structure for the edges and corners of a large circular knitting machine includes an edge base ring and several edge base assemblies; the edge base ring is annular; each edge base assembly is arranged in a ring around the axis of the edge base ring. Each of the aforementioned corner bracket assemblies includes a corner bracket block, an adjusting member, a spring, an abutting member, and a corner connecting block for mounting the corner; the two ends of each of the aforementioned adjusting members are a first end and a second end, respectively; Each of the aforementioned angular seat blocks is respectively installed on the angular seat base ring, and each of the aforementioned angular seat blocks is provided with a sliding groove, and each of the aforementioned sliding grooves is arranged radially along the angular seat base ring; each of the aforementioned sliding grooves is provided with a recessed groove at the bottom; In the same angular seat assembly, the angular connecting block is slidably connected to the slide groove, and the adjusting member is spirally connected to the angular seat cut block; the adjusting member is located on the side of the angular connecting block away from the axis of the angular seat bottom ring, the second end is located on the side of the first end away from the axis of the angular seat bottom ring, the first end abuts against the angular connecting block, the abutting member is installed on the angular connecting block, one end of the abutting member is located in the recess, the spring is located on the side of the abutting member close to the axis of the angular seat bottom ring, one end of the spring abuts against the abutting member, and the other end of the spring abuts against the recess.

[0006] Preferably, each of the adjusting components is a first screw, and each first end is formed with a tapered head; each of the angled connecting blocks has an abutment plane formed on the side away from the axis of the angled base ring; each of the first screws is arranged to gradually tilt upward from the first end to the second end. In the same angular seat assembly, the conical head abuts against the abutting plane, and the conical head is arranged tangentially to the abutting plane.

[0007] Preferably, one end of each slide groove near the axis of the bottom ring of the corner seat passes through the corresponding corner seat block; the cross-section of each slide groove is dovetail-shaped, and each corner connecting block has a slider adapted to the corresponding slide groove, and each slider is slidably connected to the corresponding slide groove.

[0008] Preferably, each of the grooves is formed on the lower side of the corresponding corner block; Each of the aforementioned abutting components is the second screw; Each of the aforementioned corner connecting blocks is provided with vertically arranged threaded through holes; In the same angular seat assembly, the second screw is helically connected to the threaded through hole, and the upper part of the second screw is located in the countersunk groove.

[0009] Preferably, each of the corner blocks is provided with a mounting hole; The base ring of the angular seat has mounting threaded holes at positions corresponding to each of the mounting holes; each mounting threaded hole is coaxially arranged with the corresponding mounting hole. Each of the mounting holes is provided with a mounting bolt, and each mounting bolt is inserted into the corresponding mounting hole and spirally connected to the corresponding mounting threaded hole.

[0010] The beneficial effects of adopting the above technical solution are as follows: By setting up a corner block, an adjusting component, a spring, a stop component, and a corner connecting block, the corner is installed on the corner connecting block. When it is necessary to move the corner closer to the axis of the corner base ring, rotating the adjusting component moves it closer to the axis of the corner base ring, which in turn pushes the corner connecting block closer to the axis of the corner base ring. This simultaneously moves the corner installed on the corner connecting block closer to the axis of the corner base ring. During the movement, the spring is gradually compressed. When it is necessary to move the corner away from the axis of the corner base ring, rotating the adjusting component moves it away from the axis of the corner base ring. The spring gradually rebounds and pushes the corner connecting block away from the axis of the corner base ring, thus simultaneously moving the corner installed on the corner connecting block away from the axis of the corner base ring. The adjustment process is relatively simple and convenient. Attached Figure Description

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0014] like Figure 1 As shown, this embodiment provides a fine-tuning structure for the edges of a large circular knitting machine, including an edge base ring 40 and several edge base assemblies 50; the edge base ring 40 is annular; each edge base assembly 50 is arranged in a ring around the axis of the edge base ring 40. Figure 1 This is a partial cross-sectional schematic diagram of the corner fine-tuning structure of the large circular milling machine. The axis of the corner seat base ring 40 (not shown in the figure) is located at... Figure 1 The left side of the partial cross-sectional structural diagram shown in the figure.

[0015] Each corner bracket assembly 50 includes a corner bracket cutting block 51, an adjusting member 52, a spring 53, an abutment member 54, and a corner connecting block 55 for mounting corners. Each corner connecting block 55 has an assembly threaded hole 55a for mounting corners.

[0016] One side of the edge is called the first face, and the other side is called the second face. The first face is used to mate with the knitting needle. It should be noted that the knitting needle is a conventional component in this field, and its specific structure, basic function, and assembly method are well known to those skilled in the art, so they will not be described in detail here. The installation method of the edge is as follows: a mounting through hole is opened on the edge, which penetrates from the first face to the second face. The mounting through hole includes a first mounting through hole segment and a second mounting through hole segment arranged coaxially. The first mounting through hole segment is closer to the first face than the second mounting through hole segment, and the diameter of the first mounting through hole segment is larger than the diameter of the second mounting through hole segment. A mounting annular step surface is formed at the connection position of the first mounting through hole segment and the second mounting through hole segment. The method of installing the edge on each edge connecting block 55 is the same. Taking the installation of the edge on one of the edge connecting blocks 55 as an example, the following explanation is provided. When the corner needs to be installed onto the corner connecting block 55, an assembly bolt is inserted into the assembly through hole. The assembly bolt includes an assembly threaded rod and an assembly nut fixed to one end of the assembly threaded rod. The end of the assembly threaded rod away from the assembly nut passes through the first assembly through hole section and the second assembly through hole section in sequence and is spirally connected to the assembly threaded hole 55a. Tightening the assembly bolt causes the assembly nut of the assembly bolt to abut against the assembly annular step surface, and the second face of the corner abuts against the corner connecting block 55. At this time, the second assembly through hole section is located between the first assembly through hole section and the assembly threaded hole 55a. It should be noted that the assembly bolt is a conventional bolt.

[0017] Each corner block 51 is installed on the corner base ring 40. Each corner block 51 has a sliding groove, which is arranged radially along the corner base ring 40. Each sliding groove has a recessed groove at the bottom.

[0018] The two ends of each adjusting member 52 are the first end and the second end, respectively.

[0019] In the same corner seat assembly 50, the corner connecting block 55 is slidably connected to the slide groove, and the adjusting member 52 is spirally connected to the corner seat cutting block 55. The adjusting member 52 is located on the side of the corner connecting block 55 away from the axis of the corner seat bottom ring 40. The second end of the adjusting member 52 is located on the side of the first end of the adjusting member 52 away from the axis of the corner seat bottom ring 40. The first end of the adjusting member 52 abuts against the corner connecting block 55. Specifically, the corner seat cutting block 55 is provided with a first threaded through hole. The first threaded through hole is located on the side of the slide groove away from the axis of the corner seat bottom ring 40. The first threaded through hole communicates with the slide groove. The adjusting member 52 is spirally connected to the first threaded through hole and abuts against the side of the corner connecting block 55 away from the axis of the corner seat bottom ring 40. The abutment 54 is mounted on the corner connecting block 55, with one end of the abutment 54 located in the recess. The spring 53 is located on the side of the abutment 54 near the axis of the corner seat bottom ring 40, and the spring 53 abuts against both the recess and the abutment 54. In this embodiment, the adjusting member 52, the spring 53, the abutment 54, and the corner connecting block 55 are located in the same plane.

[0020] Preferably, the connection structure between each adjusting member 52 and the corner connecting block 55 is as follows: each adjusting member 52 is a first screw. Each first screw is arranged gradually upward from the first end to the second end, and correspondingly, each first threaded through hole is arranged coaxially with the corresponding first screw. The first end of each first screw has a tapered head 52a; each corner connecting block 55 has an abutment plane on the side away from the axis of the corner seat bottom ring 40. In the same corner seat assembly 50, the tapered head 52a of the first screw abuts against the abutment plane of the corner connecting block 55, and the tapered head 52a of the first screw and the abutment plane of the corner connecting block 55 are arranged tangentially. With this technical solution, a line contact is formed between the tapered head 52a of the first screw and the abutment plane of the corner connecting block 55, the frictional resistance between the tapered head 52a of the first screw and the abutment plane of the corner connecting block 55 is relatively small, and the fine adjustment process is relatively smooth. Preferably, in this embodiment, the axis of each first screw forms a 45° angle with the axis of the base ring 40 of the beveled seat. The second end of each first screw is provided with a rotating head with an internal hexagonal hole.

[0021] In use, an Allen wrench is inserted into the Allen hole of the rotating head, and torque is applied to drive the first screw to rotate, thereby moving the first screw along its own axis. This causes the corner connecting block 55 to move on the slide groove, thus achieving the purpose of adjusting the corner connecting block 55. Specifically, when it is necessary to move the corner connecting block 55 closer to the axis of the corner base 40, rotating the first screw moves it closer to the axis of the corner base 40, which pushes the corner connecting block 55 closer to the axis of the corner base 40. During the movement, the spring 53 is gradually compressed. When it is necessary to move the corner connecting block 55 away from the axis of the corner base 40, rotating the first screw moves it away from the axis of the corner base 40, and the spring 53 gradually rebounds, pushing the corner connecting block 55 away from the axis of the corner base 40.

[0022] In this embodiment, the end of each slide groove near the axis of the bottom ring 40 of the corner seat passes through the corresponding corner seat block 51; the cross-section of each slide groove is dovetail-shaped, and each corner connecting block 55 has a slider adapted to the corresponding slide groove, and each slider is slidably connected to the corresponding slide groove.

[0023] Furthermore, each groove is respectively formed on the lower side of the corresponding corner seat cutting block 51; each abutment 54 is a second screw; each corner connecting block 55 is provided with a vertically arranged threaded through hole. In the same corner connecting block 55, the threaded through hole and the assembly threaded hole 55a are staggered. In the same corner seat assembly, the second screw is helically connected to the threaded through hole, and the upper part of the second screw is located in the countersunk groove. One end of the spring 53 near the axis of the corner seat bottom ring 40 abuts against the countersunk groove, and the other end of the spring 53 abuts against the upper part of the second screw.

[0024] The connection structure between each corner block 51 and the corner base ring 40 is as follows: each corner block 51 has a mounting hole; the corner base ring 40 has a threaded mounting hole at a position corresponding to each mounting hole; each threaded mounting hole is coaxially arranged with the corresponding mounting hole; each mounting hole is equipped with a mounting bolt (not shown in the figure). Each mounting bolt includes a threaded mounting rod and a nut fixed to one end of the threaded mounting rod. Each mounting hole includes a first mounting hole section and a second mounting hole section arranged coaxially. In the same mounting hole, the diameter of the first mounting hole section is larger than the diameter of the second mounting hole section. An annular stepped surface is formed at the connection position of the first and second mounting hole sections. The second mounting hole section is located between the corresponding threaded mounting hole and the first mounting hole section. The threaded mounting rod of each mounting bolt passes through the second mounting hole section of the corresponding mounting hole and is helically connected to the corresponding threaded mounting hole. The nut of each mounting bolt abuts against the annular stepped surface of the corresponding mounting hole. It should be noted that all mounting bolts are existing, standard bolts.

[0025] After adopting the above technical solution, by setting the corner block 51, adjusting member 52, spring 53, abutting member 54 and corner connecting block 55, the corner is installed on the corner connecting block 55. When it is necessary to move the corner closer to the axis of the corner base 40, rotating the adjusting member 52 will move the adjusting member 52 closer to the axis of the corner base 40, thus moving the corner installed on the corner connecting block 55 closer to the axis of the corner base 40. When it is necessary to move the corner away from the axis of the corner base 40, rotating the adjusting member 52 will move the adjusting member 52 away from the axis of the corner base 40, thus moving the corner installed on the corner connecting block 55 away from the axis of the corner base 40. The adjustment process is relatively simple and convenient.
