[0045] The detailed description and technical content of this utility model are now explained in conjunction with the accompanying drawings:
[0046] Please see Figures 2 to 3 This utility model provides a needle plate insert 20, which is disposed on a needle bed 50. The needle bed 50 is a general term for the needle cylinder, needle plate, and Schenker ring on a knitting machine. Furthermore, the knitting machine has multiple knitting needles (not shown in the figure). The needle bed 50 has a needle reference surface 51 for positioning at least one of the knitting needles, and at least one slot 52 for the needle plate insert 20 to be disposed therein. More specifically, the at least one slot 52 is disposed between adjacent knitting needles, as illustrated herein. Figure 2 It can be seen that at least one slot 52 is set to correspond to the needle reference surface 51.
[0047] The needle plate insert 20 is divided into a head section 21, a middle section 22, and a tail section 23. The head section 21 contacts the needle reference surface 51. The middle section 22 continues the head section 21 and is located within the slot 52. The tail section 23 contacts the middle section 22 and protrudes from the slot 52. The needle plate insert 20 has a foot 24, which is located in the middle section 22 and contacts the bottom of the slot 52. The middle section 22 of the needle plate insert 20 is divided into a contact area 221 and multiple non-contact areas 222 by the foot 24. As the name suggests, the contact area 221 refers to the foot 24 contacting the bottom of the slot 52, and the non-contact areas 222 do not contact the bottom of the slot 52. When the needle plate insert 20 is to be assembled into the slot 52, the gap between the non-contact areas 222 and the bottom of the slot 52 allows the adhesive to be filled in, so that the adhesive can bond the needle plate insert 20.
[0048] In summary, the needle plate insert 20 proposed in this invention differs from the prior art. The needle plate insert 20 of this invention allows the middle section 22 to contact the slot 52, specifically reducing the precision requirements during processing. Simultaneously, the needle plate insert 20 of this invention uses the foot 24 to assist in providing stability during assembly.
[0049] Please refer to the following: Figure 3 The needle plate insert 20 of this invention has a center line 25, and the foot 24 is not on the center line 25. In other words, the foot 24 is not in the center of the needle plate insert 20, and more specifically, the foot 24 is located on the side of the middle section 22 of the needle plate insert 20 near the tail section 23.
[0050] On the other hand, the needle bed 50 has a drop 53 located on the side of the slot 52 away from the needle reference surface 51. The drop 53 provides positioning for the needle plate insert 20 when it is assembled into the slot 52. The drop 53 consists of a stepped surface 531 and a vertical surface 532. The stepped surface 531 refers to the side of the drop 53 that is transverse, while the vertical surface 532 is at an angle to the stepped surface 531 (as indicated by reference numeral 533) and is generally longitudinal. The needle plate insert 20 has a bearing surface 26 located at the tail section 23 of the needle plate insert 20 and contacting the vertical surface 532 of the drop 53, so that the needle plate insert 20 rests against the drop 53 after being assembled into the slot 52. Furthermore, in this embodiment, the tail section 23 of the needle plate insert 20 does not contact the stepped surface 531 of the drop 53.
[0051] Please refer to the following: Figures 2 to 3In one embodiment, the needle plate insert 20 of this invention has a recessed groove 27, which is located at the connection between the middle section 22 and the tail section 23 of the needle plate insert 20 to facilitate the assembly of the needle plate insert 20 with the needle bed 50. Furthermore, one of the non-contact areas 222 on the side of the needle plate insert 20 facing the bottom of the slot 52 is an arc surface 28.
[0052] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
