Description

Technical Field

[0001] This utility model relates to the field of needle plate technology for flat knitting machines, and in particular to a damage-resistant needle plate for flat knitting machines. Background Technology

[0002] The needle bed, also known as the knitting plate, is a key component of the flat knitting machine. It has needle grooves containing knitting needles that work in conjunction with the latch needles to perform actions such as yarn bending and loop release. The main function of the needle bed is to fix the knitting needles and guide them in a regular up-and-down movement within the needle grooves, thereby completing the knitting of the yarn. It is a crucial link in the loop-forming process of the flat knitting machine, directly affecting the quality of the knitted fabric and production efficiency.

[0003] In the existing technology, the needle plate of the flat knitting machine is mainly used to cooperate with the movement of the knitting needles. However, the knitting needles will repeatedly impact the needle plate holes during the regular up and down movement, which makes the needle plate of the flat knitting machine easily damaged by stress during use. This limits the use of the needle plate of the flat knitting machine and makes it inconvenient to use. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a damage-resistant needle plate for flat knitting machines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a damage-resistant flat knitting machine needle plate, comprising a main body, a slot formed on the upper surface of the main body, a needle plate hole formed on the inner side of the slot, a buffer hole formed on the inner side of the needle plate hole, a spring fixedly connected to the inner side of the needle plate hole, a top plate fixedly connected to one end of the spring, a connecting rod fixedly connected to the side surface of the top plate, one end of the connecting rod extending through the interior of the spring into the interior of the buffer hole, a piston fixedly connected to one end of the connecting rod, a rubber ring provided on the outer surface of the piston, and the outer surface of the rubber ring fitting against the inner surface of the buffer hole.

[0006] As a further description of the above technical solution:

[0007] The number of slots, needle plate holes, buffer holes, springs, top plates, connecting rods and pistons is multiple, and they are arranged evenly and equidistantly along the upper surface of the main body.

[0008] As a further description of the above technical solution:

[0009] The needle plate hole has a groove inside, and a slider is fixedly connected to the surface of the top plate, with the slider located inside the groove.

[0010] As a further description of the above technical solution:

[0011] The slot is provided with multiple knitting needles, each located inside a different slot.

[0012] As a further description of the above technical solution:

[0013] The upper surface of the main body is provided with two mounting holes.

[0014] As a further description of the above technical solution:

[0015] The lower surface of the main body is provided with a snap-fit ​​groove, which is located directly below the needle plate hole.

[0016] This utility model has the following beneficial effects:

[0017] Compared with existing technologies, this anti-damage flat knitting machine needle plate, through a slot, needle plate hole, buffer hole, spring, top plate, connecting rod, piston, and rubber ring, works as follows: When the knitting needle descends along the slot, the needle foot enters the needle plate hole and contacts the top plate. The descending force pushes the top plate into the needle plate hole, which in turn causes the connecting rod to drive the piston into the buffer hole. The piston and rubber ring move and rub within the buffer hole, consuming the elastic potential energy accumulated by the spring compression. When the descending force of the knitting needle is eliminated, the spring's own elastic force pushes the top plate towards the slot, pushing the knitting needle downwards. As the needle moves and enters the designated position, in existing technologies, the needle plate of a flat knitting machine is mainly used to coordinate with the movement of the knitting needles. However, the knitting needles repeatedly impact the needle plate holes during their regular up-and-down movements, making the needle plate susceptible to damage during use. This limits the use of the needle plate and makes it inconvenient to operate. This new type of anti-damage flat knitting machine needle plate provides a buffer for the needle foot as it descends into the needle plate hole, preventing the needle foot from directly impacting the needle plate and avoiding damage during use, thus facilitating the operation of the flat knitting machine needle plate.

[0025] Reference Figure 1-5 This utility model provides a damage-resistant needle plate for a flat knitting machine, comprising a main body 1. A groove 2 is formed on the upper surface of the main body 1. A needle plate hole 3 is formed on the inner side of the groove 2. A buffer hole 4 is formed on the inner side of the needle plate hole 3. A spring 5 is fixedly connected to the inner side of the needle plate hole 3. A top plate 6 is fixedly connected to one end of the spring 5. A connecting rod 7 is fixedly connected to the side surface of the top plate 6. One end of the connecting rod 7 extends through the interior of the spring 5 into the interior of the buffer hole 4. A piston 8 is fixedly connected to one end of the connecting rod 7. A rubber ring 9 is provided on the outer surface of the piston 8. The outer surface of the rubber ring 9 is in contact with the inner surface of the buffer hole 4. There are two rubber rings 9 on one piston 8. The rubber rings 9 are in contact with the inner wall of the buffer hole 4, so that when the piston 8 moves, the rubber rings 9 provide friction. The friction force converts and reduces the elastic potential energy accumulated when the spring 5 is compressed. There are multiple slots 2, needle plate holes 3, buffer holes 4, spring 5, top plate 6, connecting rod 7 and piston 8, which are evenly and equidistantly arranged along the upper surface of the main body 1. When the knitting needle 12 descends along the slot 2, the needle foot of the knitting needle 12 enters the needle plate hole 3 and contacts the top plate 6. The descending force pushes the top plate 6 into the needle plate hole 3, thereby causing the connecting rod 7 to drive the piston 8 into the buffer hole 4. The work done by the piston 8 and the rubber ring 9 moving and frictionally in the buffer hole 4 consumes the elastic potential energy accumulated when the spring 5 is compressed. When the descending force of the knitting needle 12 is eliminated, under the action of the elastic force of the spring 5 itself, the top plate 6 is pushed towards the slot 2, pushing the knitting needle 12 to move into the waiting position.

[0026] The needle plate hole 3 has two sliding grooves 10 inside, located at the top and bottom of the needle plate hole 3 respectively. The surface of the top plate 6 is fixedly connected to two sliders 11, which are located inside the sliding grooves 10. The slots 2 are equipped with multiple knitting needles 12, which are located inside multiple slots 2 respectively. During the process of the knitting needles 12 pushing the top plate 6 to move, the sliding grooves 10 and sliders 11 restrict the movement of the top plate 6, so that the top plate 6 can only move in a fixed direction.

[0027] The upper surface of the main body 1 is provided with two mounting holes 13. The lower surface of the main body 1 is provided with a snap-fit ​​groove 14, which is located directly below the pin plate hole 3. The main body 1 can be installed and fixed through the mounting holes 13, while the snap-fit ​​groove 14 facilitates the snap-fit ​​between the main body 1 and the component.

[0028] Working principle: When the knitting needle 12 descends along the slot 2, the needle foot of the knitting needle 12 enters the needle plate hole 3 and contacts the top plate 6. The descending force pushes the top plate 6 into the needle plate hole 3, thereby causing the connecting rod 7 to drive the piston 8 into the buffer hole 4. The piston 8 and the rubber ring 9 move and rub within the buffer hole 4 to consume the elastic potential energy accumulated by the compression of the spring 5. When the descending force of the knitting needle 12 is eliminated, under the elastic force of the spring 5 itself, the top plate 6 is pushed towards the slot 2, pushing the knitting needle 12 to move into the waiting position.

[0029] 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. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
