Description

Technical Field

[0001] This utility model relates to the technical field of large circular knitting machines, and in particular to a buffer structure for a saddle. Background Technology

[0002] The circular knitting machine, also known as a circular weft knitting machine, is a core piece of equipment in the textile industry for mass production of knitted fabrics. The saddle of the circular knitting machine, also called the cam seat, is a key transitional component that connects the frame and the cams and controls the movement trajectory of the knitting needles. Essentially, it serves as the mounting carrier for the cams and the fixed frame for the knitting needle trajectory, directly determining the accuracy and stability of the fabric knitting. To prevent vibration from affecting the saddle, most saddles are equipped with shock-absorbing structures. These structures can prevent vibration from negatively impacting knitting accuracy, component lifespan, and fabric quality, thus improving processing quality and efficiency. Therefore, a buffer structure for the saddle is particularly needed.

[0003] However, most existing saddles cannot adjust the deformation of the damping springs due to their damping structure. The damping springs have poor load matching capabilities, resulting in poor damping effect on the saddle and affecting the quality and efficiency of the manufacturing process.

[0004] To address the aforementioned issues, a search revealed a patent with publication number CN209481930U that discloses an anti-skid saddle for a circular knitting machine. The patent states that "in existing circular knitting machines with loop pile, the hook knife moves up and down at high speed within the knife cylinder groove. Because the mounting grooves for the starting and ending knife angles on the saddle are vertically oriented, and the track on the ending knife angle connects with the track on the starting knife angle, the ending knife angle applies pressure along the track direction, resulting in an inclined pressure direction. When adjusting the position of the starting knife angle, it can only move up and down along the vertically oriented mounting groove. This causes the distance between the track on the ending knife angle and the track on the starting knife angle to constantly change. Due to inertia, the hook knife may move beyond its design range." The phenomenon of tool skipping, also known as downward or upward drifting, occurs between the starting and ending corners of the cutting edge. When downward drifting occurs, the hook may jump off the track and break; when upward drifting occurs, the hook position changes during the upward movement, failing to hook the fabric and resulting in defects. The tool saddle described in this invention eliminates the possibility of tool skipping at its source. It requires minimal modification to the existing tool saddle forming mold, reducing mold adjustments. It eliminates the need for a forming milling cutter, reducing processing difficulty. The milling groove angle is the same as the pressing angle of the ending corner, simplifying the forming process. However, most existing saddle damping structures cannot adjust the deformation of the damping spring, resulting in poor load matching capacity of the damping spring and poor damping effect on the saddle, which affects processing quality and efficiency.

[0005] In light of this, in-depth research into the aforementioned issues led to the creation of this case. Utility Model Content

[0017] 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.

[0018] Please see Figure 1-5The present invention provides a technical solution: a buffer structure for a saddle, including a mounting base 1, an adjustment mechanism 2 at one end of the mounting base 1, a shock-absorbing mechanism 3 at one end of the adjustment mechanism 2, and a saddle 4 at one end of the shock-absorbing mechanism 3; The adjustment mechanism 2 includes a motor 201. The output end of the motor 201 is connected to a connecting shaft 202. A rotating block 203 is mounted on one end of the connecting shaft 202. Pull rods 205 are mounted on both ends of the rotating block 203. A movable plate 207 is connected to one end of the pull rods 205. A connecting block 208 is mounted on one side of the movable plate 207, and an adjustment plate 209 is mounted on one side of the connecting block 208. Based on the arrangement of the mounting base 1, motor 201, connecting shaft 202, rotating block 203, pull rod 205, movable plate 207, connecting block 208, and adjustment plate 209, when the deformation of the first damping spring 304 needs to be adjusted... The motor 201 causes the rotating block 203 to rotate. At this time, under the action of the first connecting column 204, the two pull rods 205 will be driven to move linearly. The other end of the pull rod 205 will drive the moving plate 207 to move through the second connecting column 206. At this time, the two moving plates 207 can simultaneously drive the two adjusting plates 209 to move linearly through the connecting block 208. The distance between the adjusting plate 209 and the mounting plate 303 can be controlled, thereby adjusting the deformation of the first damping spring 304. The first damping spring 304 has good load matching ability and better damping effect on the saddle 4, improving the quality and efficiency of processing.

[0019] Furthermore, the rotating block 203 is equipped with first connecting posts 204 at both ends. The pull rod 205 is connected to the rotating block 203 through the first connecting posts 204. The first connecting post 204 is a key component for the change from rotational motion to linear motion. When the rotating block 203 rotates, the first connecting post 204 can rotate around its own axis. At the same time, the arc trajectory of the rotating block 203 drives one end of the pull rod 205 to perform arc-shaped motion, while the other end of the pull rod 205 can carry the moving plate 207 to perform linear motion, thereby controlling the position of the adjusting plate 209 and realizing the adjustment of the deformation of the first damping spring 304.

[0020] Furthermore, one end of the pull rod 205 is connected to a second connecting post 206. The pull rod 205 is connected to the movable plate 207 through the second connecting post 206. With the setting of the second connecting post 206, the end of the pull rod 205 away from the rotating block 203 can be connected to the movable plate 207 through the second connecting post 206. When one end of the pull rod 205 is moved by the rotating block 203, the other end of the pull rod 205 can move the movable plate 207 through the second connecting post 206.

[0021] Furthermore, a limiting block 210 is installed on one side surface of the movable plate 207, and a limiting groove 211 is opened on one side inner wall of the mounting base 1. With the setting of the limiting block 210 and the limiting groove 211, when the movable plate 207 is moved by the pull rod 205, the limiting block 210 will slide in the limiting groove 211. Under the action of the limiting block 210, the movable plate 207 can only move linearly in the direction of the opening of the limiting groove 211. The limiting block 210 plays an auxiliary and limiting role in the movement of the movable plate 207.

[0022] Furthermore, the shock absorption mechanism 3 includes a first moving rod 301, one end of which is fitted with a first auxiliary rod 302, and the other end of which is connected to a mounting plate 303. A first shock absorption spring 304 is mounted on one side surface of an adjusting plate 209, and the other end of which is connected to a connecting ring 305. A mounting block 306 is mounted on the outer wall of the connecting ring 305, one end of which is connected to a support frame 307, and the other end of which is connected to a support plate 308. A lifting plate 309 is mounted on one side surface of the support plate 308, and a second moving rod 310 is mounted on one side surface of the adjusting plate 209. A second auxiliary rod 311 is fitted on one end of the second moving rod 310, and a second shock absorption spring 312 is mounted on one side surface of the connecting block 208. The shock absorption mechanism 3 is connected via the first moving rod 301, the first auxiliary rod 302, the mounting plate 303, and the first shock absorption spring 304. 4. The arrangement of the connecting ring 305, mounting block 306, support frame 307, support plate 308, lifting plate 309, second moving rod 310, second auxiliary rod 311, and second damping spring 312 is as follows: When the lifting plate 309 is subjected to pressure and descends, the support frames 307 at both ends of the support plate 308 rotate. One end of the support frame 307 slides the connecting ring 305 on the outer wall of the first auxiliary rod 302 through the mounting block 306. When the connecting ring 305 slides, it will squeeze the first damping spring 304. At this time, the first damping spring 304 will generate a rebound force in the opposite direction when subjected to pressure, thus achieving the effect of damping. At the same time, when the lifting plate 309 is pressed down, the second damping spring 312 will also be subjected to pressure. The second damping spring 312 will also generate a rebound force in the opposite direction of pressure, thus achieving the effect of damping. In this way, the pressure on the saddle 4 mounted on the surface of the lifting plate 309 can be buffered and damped.

[0023] Furthermore, the connecting ring 305 is sleeved on the outer wall of the first auxiliary rod 302. The connecting ring 305 forms a telescopic structure with the adjusting plate 209 through the first damping spring 304. With the setting of the first moving rod 301 and the first auxiliary rod 302, when the adjusting plate 209 moves linearly, one end of the first moving rod 301 can move inside the first auxiliary rod 302, so that the adjusting plate 209 has space to move.

[0024] Furthermore, one side surface of the second auxiliary rod 311 is connected to the lifting plate 309, and one end of the second damping spring 312 is connected to the lifting plate 309. The lifting plate 309 forms a telescopic structure with the adjusting plate 209 through the second damping spring 312. With the setting of the second moving rod 310 and the second auxiliary rod 311, the lifting movement of the lifting plate 309 will cause the second damping spring 312 to extend and retract. When the second damping spring 312 extends and retracts, the second auxiliary rod 311 will move at one end of the second moving rod 310, which can assist and limit the extension and retraction movement of the second damping spring 312.

[0025] Working principle: When the deformation of the first damping spring 304 needs to be adjusted, the motor 201 causes the rotating block 203 to rotate. At this time, under the action of the first connecting column 204, the two tie rods 205 will be driven to move linearly. The other end of the tie rod 205 will move the moving plate 207 through the second connecting column 206. At this time, the two moving plates 207 can simultaneously drive the two adjusting plates 209 to move linearly through the connecting block 208. The distance between the adjusting plate 209 and the mounting plate 303 can be controlled, thereby adjusting the deformation of the first damping spring 304. The first damping spring 304 has good load matching capability and better damping effect on the saddle 4, improving the quality and efficiency of processing. When the lifting plate 309 is lowered under pressure, the support frames 307 at both ends of the support plate 308 rotate. One end of the support frame 307 slides the connecting ring 305 on the outer wall of the first auxiliary rod 302 through the mounting block 306. When the connecting ring 305 slides, it will squeeze the first damping spring 304. At this time, the first damping spring 304 will generate a rebound force in the opposite direction when it is under pressure, thus achieving the effect of damping. At the same time, when the lifting plate 309 is pressed down, the second damping spring 312 will also be under pressure. The second damping spring 312 will also generate a rebound force in the opposite direction of pressure, thus achieving the effect of damping. In this way, the pressure on the saddle 4 mounted on the surface of the lifting plate 309 can be buffered and damped.
