Description

Technical Field

[0001] This utility model relates to the field of flat knitting machine technology, specifically a needle plate structure for a flat knitting machine. Background Technology

[0002] The needle plate structure of existing flat knitting machines generally includes two types. One type is to form needle grooves that are evenly spaced along the length of the needle plate body to accommodate knitting needles directly on the needle plate body. The other type is to form insert slots that are evenly spaced along the length of the needle plate body on the needle plate body, and insert an insert into each insert slot. The gap between two adjacent inserts forms a needle groove to accommodate knitting needles.

[0003] While needle grooves formed by inserts can maintain deformed or damaged needles by replacing the inserts, the maintenance cost is high, and the assembly of the needle plate body and inserts is difficult, which indirectly increases the product cost. In particular, in the knitting of coarse fabrics such as sweaters, the first type of needle plate mentioned above is generally used to save on usage costs. However, this type of needle plate is not convenient for replacing inserts. Therefore, a needle plate that is easy to replace inserts and has a relatively low assembly difficulty is needed. Utility Model Content

[0004] Technical problems to be solved

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a needle plate structure for a flat knitting machine.

[0006] Technical solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a needle plate structure for a flat knitting machine, comprising an upper panel, a row of needle-holding holes on the right side of the upper panel, each needle-holding hole having a knitting needle inserted inside, an annular groove on the inner sidewall of the needle-holding hole, a sealing ring inside the annular groove, a set of mounting plates fixedly connected to the side of the upper panel away from the knitting needle, assembly holes fixedly connected to both ends of the upper panel, anti-slip texture on the right end of the knitting needle, an elastic locking mechanism for fixing the knitting needle inside the upper panel, the number of elastic locking mechanisms being the same as the number of needle-holding holes and corresponding in position, a push-pull member for pushing the elastic locking mechanism between the elastic locking mechanism and the upper panel, the elastic locking mechanism including an inclined groove on the bottom surface of the upper panel, and a certain angle between the inclined groove and the needle-holding hole, a connecting rod slidably arranged inside the inclined groove, and a base plate fixedly installed on the bottom surface of the upper panel by screws.

[0008] The aforementioned elastic locking mechanism further includes a through groove inside the upper panel, the through groove being located between the locking pin hole and the inclined groove, and the upper and lower ends of the through groove being connected to the locking pin hole and the inclined groove respectively. A locking block is provided inside the through groove, the bottom end of the locking block being fixedly connected to the outer surface of the connecting rod, and a compression spring being fixedly connected to the right end of the connecting rod.

[0009] As mentioned above, the top of the card block is provided with a row of burrs that match the outer surface of the knitting needle, and the hardness value of the material of the burrs is not lower than HRA.

[0010] As described above, the push-pull component includes a sliding hole formed on the upper surface of the top plate. The bottom end of the sliding hole is connected to the inclined groove. A sliding plate is slidably connected inside the sliding hole. The bottom end of the sliding plate is fixedly connected to the outer surface of the linkage rod. The top end of the sliding plate extends to the outside of the sliding hole and is fixedly connected to a toggle.

[0011] Beneficial effects:

[0012] Compared with existing technologies, the needle plate structure of this flat knitting machine has the following advantages:

[0013] 1. The main body of the needle plate structure consists of a top panel and a bottom plate. Because the bottom surface of the top panel is detachably installed to the bottom plate by screws, it is easy to open inclined grooves, through grooves and sliding holes inside the top panel. It is also easy to assemble the linkage rod, locking block and sliding plate into the inside of the needle plate body, thereby reducing the assembly difficulty of the needle plate.

[0014] Second, the needle plate structure, through the combined design of push-pull parts and elastic locking mechanism, pushes and twists left and right, causing the slide plate, connecting rod and locking block to move left and right together. Because there is a certain angle between the inclined groove and the needle hole and the knitting needle, the locking bar on the locking block can release the locking effect on the outer surface of the knitting needle, and can lock and separate the locking block and the knitting needle, so as to realize the quick replacement of the knitting needle.

[0015] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0025] 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.

[0026] like Figure 1-4 As shown, this utility model provides a technical solution: a needle plate structure for a flat knitting machine, including an upper panel 1. A row of needle-holding holes 2 is opened on the right side of the upper panel 1. A knitting needle 3 is inserted into each needle-holding hole 2. An annular groove is opened on the inner side wall of the needle-holding hole 2, and a sealing ring 8 is installed inside the annular groove. When the knitting needle 3 is inserted into the needle-holding hole 2, the inner ring of the sealing ring 8 contacts the outer surface of the knitting needle 3, achieving a sealing effect between the knitting needle 3 and the needle-holding hole 2, preventing external impurities from entering the needle-holding hole 2. A set of mounting plates 6 is fixedly connected to the side of the upper panel 1 away from the knitting needle 3. Mounting plates 6 are fixedly connected to both ends of the upper panel 1. The mounting hole 7 is used to install the needle plate on the flat knitting machine through the mounting plate 6 and the mounting hole 7. The right end of the needle 3 is provided with anti-slip texture 9. The upper panel 1 is provided with an elastic locking mechanism 4 for fixing the needle 3. The number of elastic locking mechanisms 4 is the same as the number of needle holes 2 and their positions correspond. A push-pull member 5 is provided between the elastic locking mechanism 4 and the upper panel 1 for pushing the elastic locking mechanism 4. The elastic locking mechanism 4 includes a slanted groove 41 opened on the bottom surface of the upper panel 1, and there is a certain angle between the slanted groove 41 and the needle hole 2. A connecting rod 42 is slidably arranged inside the slanted groove 41. The bottom surface of the upper panel 1 is fixedly installed with a base plate 10 by screws.

[0027] The elastic locking mechanism 4 also includes a through groove 43 opened inside the upper panel 1. The through groove 43 is located between the pin hole 2 and the inclined groove 41, and the upper and lower ends of the through groove 43 are connected to the pin hole 2 and the inclined groove 41 respectively. A locking block 44 is provided inside the through groove 43. The bottom end of the locking block 44 is fixedly connected to the outer surface of the connecting rod 42. A compression spring 45 is fixedly connected to the right end of the connecting rod 42. A row of piercings 441 that match the outer surface of the knitting needle 3 is provided on the top of the locking block 44. Under the elastic force of the compression spring 45, the connecting rod 42 and the locking block 44 move to the left, so that the piercings 441 on the locking block 44 are tightly locked on the outside of the knitting needle 3, thus completing the fastening installation of the knitting needle 3.

[0028] The material hardness of the 441 is not less than 92HRA, so that the 441 is slightly embedded in the outer surface of the needle 3, which increases the friction coefficient between the 44 and the needle 3 and ensures the locking effect of the 44 on the needle 3.

[0029] The push-pull component 5 includes a sliding hole 51 formed on the upper surface of the upper panel 1. The bottom end of the sliding hole 51 is connected to the inclined groove 41. A sliding plate 52 is slidably connected inside the sliding hole 51. The bottom end of the sliding plate 52 is fixedly connected to the outer surface of the connecting rod 42. The top end of the sliding plate 52 extends to the outside of the sliding hole 51 and is fixedly connected to a lever 53. Pushing the lever 53 left and right can make the sliding plate 52, the connecting rod 42 and the locking block 44 move left and right, so that the locking block 44 and the knitting needle 3 can be engaged or disengaged.

[0030] Working principle: The main body of the needle plate structure consists of an upper panel 1 and a bottom plate 10. Because the bottom surface of the upper panel 1 is detachably installed to the bottom plate 10 by screws, it is easy to open the inclined groove 41, through groove 43 and sliding hole 51 inside the upper panel 1. It is also easy to assemble the connecting rod 42, the locking block 44 and the sliding plate 52 into the inside of the needle plate body, thereby reducing the assembly difficulty of the needle plate.

[0031] When using this needle plate, it is first installed on the flat knitting machine via the mounting plate 6 and assembly hole 7 fixed on the side of the upper panel 1. When one of the knitting needles 3 is worn or deformed and needs to be replaced, the push-pull part 5 and the elastic locking mechanism 4 work together to facilitate the replacement of one of the knitting needles 3. During the replacement of the knitting needle 3, the lever 53 is first pushed to the right, causing the slide plate 52, the connecting rod 42 and the locking block 44 to move to the right together. Because there is a certain angle between the inclined groove 41 and the needle hole 2 and the knitting needle 3, the movement continues until the locking bar 44 on the locking block 44 is engaged. 1. Release the locking action on the outer surface of the knitting needle 3, and the old knitting needle 3 can be pulled out from the inside of the needle-holding hole 2. At the same time, replace it with a new knitting needle 3 and insert it into the inside of the needle-holding hole 2. Then release the lever 53. Under the elastic force of the compression spring 45, the connecting rod 42 and the locking block 44 move to the left, so that the locking bar 441 on the locking block 44 can be tightly locked on the outside of the knitting needle 3, completing the installation of the knitting needle 3. In summary, the knitting needle 3 can be quickly replaced, and the replacement process is more convenient. The elastic force of the compression spring 45 must meet the requirements for the tight installation of the knitting needle 3.
