Description

Technical Field

[0001] The utility model relates to a yarn reciprocating swing mechanism for a sock machine, belonging to the field of textiles. Background Art

[0002] The yarn guiding structure on the sock machine generally includes a plurality of shuttles, and a yarn guiding porcelain tube is installed at the front end of the shuttle. In order to ensure that the yarn can be replaced normally when the socks are knitted and to avoid that the yarn on one side can be more obviously seen from the other side, the outermost shuttle of the yarn guiding structure needs to be able to swing back and forth to achieve the staggered left and right positions when weaving the yarn. The method of using the expansion and contraction of the cylinder and the coordination of the spring is a common structure that enables the shuttle to swing back and forth, that is, in the initial state, the cylinder and the spring are arranged perpendicular to the shuttle. When the cylinder is extended, the shuttle is squeezed and rotates around the rotating shaft. At this time, the end of the shuttle away from the yarn guiding porcelain tube squeezes the spring, causing the spring to produce elastic deformation. When the cylinder contracts, the shuttle is forced to reset under the action of the spring rebound force. Repeating the above action can make the shuttle swing back and forth. In the initial state, the spring arranged perpendicular to the shuttle and the supporting structure of the spring are exposed on the outside of the shuttle seat, and there is a situation that a large space around the shuttle seat is occupied. Therefore, it is necessary to design a sock machine yarn reciprocating swing mechanism in which the structure for resetting the shuttle is in a hidden state. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model aims to provide a yarn reciprocating swing mechanism for a sock machine to solve the problems raised in the above-mentioned background technology. The utility model realizes that the structure for resetting the shuttle is in a hidden state, thereby reducing the space occupied by the structure for resetting the shuttle.

[0004] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: a sock machine yarn reciprocating swing mechanism, including a shuttle seat, one side of the shuttle seat is provided with a strip groove, a shuttle is rotatably installed in the strip groove through a rotating shaft, a yarn guide porcelain tube for limiting the movement trajectory of the yarn is installed at the end of the shuttle away from the strip groove, a support plate is installed on the lower side of the strip groove, a cylinder for squeezing the shuttle is installed on the side of the support plate away from the shuttle seat, the movable end of the cylinder is in sliding contact with the shuttle, and a resetting member for resetting the shuttle is installed on the side of the strip groove away from the shuttle.

[0005] Further, the reset member includes a U-shaped plate. A detachable U-shaped plate is installed on one side of the strip-shaped groove close to the shuttle. A vertically arranged inner rotating roller is rotatably installed inside the U-shaped plate. An outer rotating roller arranged vertically is rotatably installed on the side of the U-shaped plate facing the shuttle. Two horizontally arranged connecting ropes are provided between the inner rotating roller and the outer rotating roller. One end of the connecting rope is fixedly connected to the shuttle. Two connecting rods are fixedly connected to the side of the U-shaped plate facing away from the shuttle. The end of the connecting rod away from the U-shaped plate is fixedly connected to a positioning plate. The positioning plate is installed in the strip-shaped groove. Two horizontally arranged guide holes are formed on the side of the positioning plate facing the U-shaped plate. Guide rods are inserted into the guide holes. The two ends of the connecting ropes away from the shuttle are respectively fixedly connected to the two guide rods. A limiting disc is fixedly connected to the end of the guide rod away from the connecting rope. A spring is sleeved on the guide rod. The spring is arranged between the limiting disc and the positioning plate.

[0006] Further, two through holes are formed in the strip-shaped groove. Threaded holes aligned with the through holes are formed at both ends of the U-shaped plate. Connecting screws are inserted into the through holes. One end of the connecting screw is threadedly connected to the threaded hole.

[0007] Further, a U-shaped frame is arranged outside the through hole. Both ends of the U-shaped frame are fixedly connected to the shuttle seat. Two small holes aligned with the through holes are formed on one side of the U-shaped frame. The connecting screw passes through the small holes.

[0008] Further, two fixing holes are formed on one side of the shuttle seat. The fixing holes are arranged in a staggered manner with the strip-shaped groove.

[0009] Further, a notch is formed on one side of the shuttle close to the shuttle seat. The notch is arranged on the side of the shuttle facing away from the cylinder.

[0010] Further, a cushion block is arranged between the support plate and the shuttle seat. The cushion block is fixedly connected to the shuttle seat. The support plate is fixedly connected to the cushion block through a plurality of screws.

[0011] The beneficial effects of the utility model:

[0012] 1. The shuttle is connected to the guide rod by a connecting rope. When the cylinder expands and contracts, the shuttle rotates around the rotating shaft. At this time, the shuttle drives the guide rod to slide along the guide hole on the positioning plate through the connecting rope. At this time, the positioning plate and the limiting disc jointly act to compress the spring, causing the spring to produce elastic deformation. When the cylinder contracts, the shuttle is reset under the action of the resilience of the spring. Since components such as the spring, the guide rod, the U-shaped plate, and the positioning plate are all located in the strip-shaped groove of the shuttle seat, the structure for resetting the shuttle is in a hidden state, reducing the space occupied by the structure for resetting the shuttle.

[0013] 2. When installing the U-shaped plate in the strip groove using the connecting screws, align the screw holes on the U-shaped plate with the perforations. Then, pass one end of the connecting screw through the small hole on the U-shaped frame and the perforation on the shuttle base and screw it into the screw hole to complete the assembly of the shuttle base and the U-shaped plate. When the connecting screw is difficult to turn due to rust or other reasons, the connecting screw can be cut off using the gap between the U-shaped frame and the shuttle base, reducing the difficulty of disassembly and assembly.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] To make the technical means, creative features, achieved purposes, and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please refer to Figure 1 and Figure 2, the present utility model provides a technical solution: a reciprocating swing mechanism for yarn of a sock knitting machine, including a shuttle seat 1. A strip-shaped groove 3 is formed on one side of the shuttle seat 1, and two fixing holes 2 are formed on one side surface of the shuttle seat 1. The fixing holes 2 and the strip-shaped groove 3 are arranged in a staggered manner. By providing the fixing holes 2 on the shuttle seat 1 and installing bolts through the fixing holes 2 at the required positions, the position of the shuttle seat 1 is restricted.

[0023] Refer to Figures 1 - 3 , a shuttle 10 is rotatably installed in the strip-shaped groove 3 through a rotating shaft. A yarn guiding porcelain tube 11 for restricting the moving track of the yarn is installed at one end of the shuttle 10 away from the strip-shaped groove 3. A support plate 8 is installed on the lower side of the strip-shaped groove 3. A cushion block 7 is provided between the support plate 8 and the shuttle seat 1, and the cushion block 7 is fixedly connected to the shuttle seat 1. The support plate 8 is fixedly connected to the cushion block 7 through a plurality of screws. The cushion block 7 plays a role in connecting the support plate 8 and the shuttle seat 1. A cylinder 9 for extruding the shuttle 10 is installed on one side surface of the support plate 8 away from the shuttle seat 1. The movable end of the cylinder 9 is in sliding contact with the shuttle 10. An opening is formed on one side surface of the shuttle 10 close to one side of the shuttle seat 1. The opening is arranged on the side of the shuttle 10 away from the cylinder 9. The design of the opening prevents the rotation of the shuttle 10 from interfering with the shuttle seat 1.

[0024] Refer to Figures 1 - 5 , a detachable U-shaped plate 12 is installed on one side of the shuttle 10 in the strip-shaped groove 3. Two through holes are formed in the strip-shaped groove 3. Threaded holes aligned with the through holes are formed at both ends of the U-shaped plate 12. Connecting screws 14 are inserted into the through holes. One end of the connecting screw 14 is threadedly connected in the threaded hole. A U-shaped frame 13 is provided outside the through hole. Both ends of the U-shaped frame 13 are fixedly connected to the shuttle seat 1. Two small holes aligned with the through holes are formed on one side surface of the U-shaped frame 13. The connecting screw 14 passes through the small holes. When installing the U-shaped plate 12 in the strip-shaped groove 3 by using the connecting screw 14, the threaded holes on the U-shaped plate 12 are aligned with the through holes. Then, one end of the connecting screw 14 is passed through the small holes on the U-shaped frame 13 and the through holes on the shuttle seat 1 and then screwed into the threaded hole to complete the assembly of the shuttle seat 1 and the U-shaped plate 12. When the connecting screw 14 is difficult to turn due to corrosion or other reasons, the connecting screw 14 can be cut off by using the gap between the U-shaped frame 13 and the shuttle seat 1, reducing the difficulty of disassembly and assembly.

[0025] Refer to Figures 1 - 5, a vertically arranged inner rotating roller 18 is rotatably installed inside the U-shaped plate 12, and a vertically arranged outer rotating roller 17 is rotatably installed on the side of the U-shaped plate 12 facing the shuttle 10. There are two horizontally arranged connecting ropes 19 between the inner rotating roller 18 and the outer rotating roller 17. The inner rotating roller 18 and the outer rotating roller 17 support the connecting rope 19 to prevent the connecting rope 19 from generating sliding friction and wear at the corners of components such as the shuttle base 1 and the U-shaped plate 12. One end of the connecting rope 19 is fixedly connected to the shuttle 10. Two connecting rods 6 are fixedly connected to the side of the U-shaped plate 12 facing away from the shuttle 10. The end of the connecting rod 6 far from the U-shaped plate 12 is fixedly connected to a positioning plate 5. The positioning plate 5 is installed in the strip-shaped groove 3. Two horizontally arranged guide holes are opened on the side of the positioning plate 5 facing the U-shaped plate 12. Guide rods 15 are inserted into the guide holes. The two ends of the connecting rope 19 far from the shuttle 10 are respectively fixedly connected to the two guide rods 15. A limiting disc 16 is fixedly connected to the end of the guide rod 15 far from the connecting rope 19. A spring 4 is sleeved on the guide rod 15. The spring 4 is arranged between the limiting disc 16 and the positioning plate 5. By using the connecting rope 19 to connect the shuttle 10 and the guide rod 15, when the air cylinder 9 expands and contracts, the shuttle 10 rotates around the rotating shaft. At this time, the shuttle 10 drives the guide rod 15 to slide along the guide hole on the positioning plate 5 through the connecting rope 19. At this time, the positioning plate 5 and the limiting disc 16 jointly act to compress the spring 4, causing the spring 4 to generate elastic deformation. When the air cylinder 9 contracts, under the action of the resilience of the spring 4, the shuttle 10 is reset. Since components such as the spring 4, the guide rod 15, the U-shaped plate 12, and the positioning plate 5 are all inside the strip-shaped groove 3 of the shuttle base 1, the structure for resetting the shuttle 10 is in a hidden state, reducing the space occupied by the structure for resetting the shuttle 10.

[0026] Although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
