Description

Technical Field

[0001] This utility model relates to the field of knitting machine technology, and specifically to a cutting assembly for a color-changing head. Background Technology

[0002] Existing color-changing heads used in knitting machines are assembled with multiple color-changing head cutter assemblies. Each color-changing head cutter assembly includes an upper fixed plate, a lower fixed plate, a hook needle, and a cutter. The upper and lower fixed plates are fixedly installed, and the hook needle and cutter are clamped between them. In existing color-changing head cutter assemblies, the cutter is fixed to the upper and lower fixed plates and its position cannot be moved. When processing certain special yarns, the yarn cutting position differs, requiring replacement of the color-changing head cutter assembly. This increases manufacturing costs; without replacing the color-changing head cutter assembly, the required functionality cannot be met.

[0003] Therefore, based on the aforementioned shortcomings of the existing color-changing head cutter assembly, it is necessary to improve the existing color-changing head cutter assembly. Utility Model Content

[0004] The purpose of this invention is to provide a color-changing head cutter assembly that addresses the shortcomings of existing technologies by solving the defect that the cutter cannot be moved.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution.

[0006] A color-changing head cutter assembly includes an upper fixed plate, a lower fixed plate, a hook, and a cutter. The upper fixed plate and the lower fixed plate are fixedly installed. The hook and the cutter are clamped between the upper fixed plate and the lower fixed plate. An adjusting rod is fixedly installed between the upper fixed plate and the lower fixed plate. The adjusting rod has multiple adjusting holes. The cutter has multiple positioning holes. A screw passes through the adjusting hole of the adjusting rod and is fixed to the positioning hole of the cutter.

[0007] Furthermore, the adjusting rod has a fixing hole on its body for fixing the adjusting rod to the upper fixing plate and the lower fixing plate.

[0008] Furthermore, the cutter has a longitudinally arranged center positioning hole, upper positioning hole, and lower positioning hole, which are used for connection and positioning with the adjusting rod.

[0009] Furthermore, the upper part of the adjusting rod is provided with a longitudinally arranged center adjusting hole, an upper adjusting hole, and a lower adjusting hole. The three adjusting holes are used to adjust and position the cutting blade with the positioning hole.

[0010] Furthermore, the upper part of the adjusting rod is thicker than the rod body, and both sides of the rod body can be tightly attached to the upper fixing plate and the lower fixing plate, respectively.

[0011] Furthermore, the distance between the central adjustment hole and the upper and lower adjustment holes is greater than the distance between the central positioning hole and the upper and lower positioning holes, respectively. This allows the adjustment holes and positioning holes to be misaligned, enabling fine-tuning of the cutter's position.

[0012] Furthermore, a limiting window is provided in the middle of the upper fixing plate, and the cutting tool has a limiting part located within the limiting window, so that the position movement of the cutting tool is stable.

[0013] The advantages of this utility model are as follows: by adding an adjusting rod and opening positioning holes and adjusting holes on the cutter and the adjusting rod respectively, the position of the cutter relative to the adjusting rod can be adjusted, so that it can be matched with different yarns, with low manufacturing cost and convenient adjustment.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] See Figure 1 —— Figure 8 This utility model discloses a color-changing head cutter assembly comprising: an upper fixing plate 01, a lower fixing plate 02, a hook 03, a cutter 04, and a limiting window 05. The upper fixing plate 01 and the lower fixing plate 02 are fixedly installed. The hook 03 and the cutter 04 are sandwiched between the upper fixing plate 01 and the lower fixing plate 02. A limiting window 05 is provided in the middle of the upper fixing plate 01. The cutter 04 has a limiting part 06 located within the limiting window 05. An adjusting rod 07 is fixedly installed between the upper fixing plate 01 and the lower fixing plate 02. The adjusting rod 07 has multiple adjusting holes, and the cutter 04 has multiple positioning holes. A screw passes through the adjusting holes of the adjusting rod 07 and is fixed to the positioning holes of the cutter 04, thereby realizing the positional adjustment and fixation of the cutter 04 and the adjusting rod 07.

[0025] See Figure 2 , Figure 3 The cutter 04 of this utility model has three positioning holes, namely a central positioning hole 08, an upper positioning hole 09, and a lower positioning hole 010, which are arranged longitudinally.

[0026] See Figure 4 The adjusting rod 07 of this utility model has a fixing hole 012 on its rod body 011, through which the upper fixing plate 01, the lower fixing plate 02 and the adjusting rod 07 are fixed together.

[0027] See Figure 5 The upper part of the adjusting rod 07 of this utility model is thicker than the rod body 011 so that the upper fixing plate 01 and the lower fixing plate 02 can fit tightly against the rod body 011. The upper part of the adjusting rod 07 has three adjusting holes, namely the center adjusting hole 013, the upper adjusting hole 014, and the lower adjusting hole 015, which are arranged longitudinally.

[0028] See Figure 6 — Figure 8 In this invention, the distance between the central adjustment hole 013 of the adjustment rod 07 and the upper adjustment hole 014 and the lower adjustment hole 015 is greater than the distance between the central positioning hole 08 of the cutter 04 and the upper positioning hole 09 and the lower positioning hole 010. This allows at least one set of positioning holes and adjustment holes to be misaligned, thereby enabling the relative movement adjustment and positioning of the cutter 04 and the adjustment rod 07.

[0029] like Figure 6 As shown, the adjusting screw is passed through the center adjusting hole 013 of the adjusting rod 07 and fixed together with the center positioning hole 08 of the cutter 04, which serves as the reference position of the cutter 04.

[0030] like Figure 7As shown, by passing the adjusting screw through the lower adjusting hole 015 of the adjusting rod 07 and fixing it together with the lower positioning hole 010 of the cutter 04, the cutter 04 can be adjusted downward and retracted, thereby achieving the position adjustment effect of the cutter 04 to match the needs of different yarns.

[0031] like Figure 8 As shown, by passing the adjusting screw through the upper adjusting hole 014 of the adjusting rod 07 and fixing it together with the upper positioning hole 09 of the cutter 04, the cutter 04 can be adjusted upward and extended, thereby achieving the position adjustment effect of the cutter 04 to match the needs of different yarns.

[0032] Of course, the above-described embodiments are merely preferred examples of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of this utility model should be included within the scope of the claims of this utility model.
