Description

Technical Field

[0001] The utility model relates to the technical field of piezoelectric jacquard combs, in particular to a folded piezoelectric jacquard comb. Background Art

[0002] At present, the jacquard warp knitting machines on the market usually use piezoelectric jacquard needles. Usually, multiple piezoelectric ceramic jacquard needles are combined into a piezoelectric needle block with a length of about 1 to 2 inches. Many piezoelectric needle blocks are fixed closely and side by side on one side of the jacquard bar, and the cumulative total width is equivalent to that of the jacquard bar, forming a jacquard jacquard bar. The jacquard bar is suitable for making complex patterns on warp knitted fabrics. During the production process, the jacquard bar can perform overall lateral movement like other ordinary bars. At the same time, each yarn guide needle installed on the jacquard needle block can also be driven by a piezoelectric element to perform a separate additional lateral movement. Through the superposition of these two lateral movements, the jacquard bar can provide more pattern possibilities than ordinary bars. Since the yarn routing is relatively dense, in order to prevent the yarn from falling into the gap between the jacquard needles during movement to cause yarn breakage and to avoid the wear of the jacquard needle plate by the yarn, a baffle is generally installed on the front or back of the jacquard needle plate;

[0003] The existing baffle can only block and protect the yarn, but cannot protect the yarn guide needle when the piezoelectric jacquard comb is not in use, so that the yarn guide needle is easily damaged if it is hit by an external impact when not in use. Therefore, it is urgent to design a foldable piezoelectric jacquard comb to solve the above problem. Utility Model Content

The number of comb blades 3 and jacquard yarn guide needles 4 are both several, and the jacquard yarn guide needle 4 is arranged between two adjacent protection teeth 11. A first buckle assembly 23 is arranged on one side of the rotating plate 9, and a second buckle assembly 24 is arranged on the other side of the rotating plate 9. The comb seat 2 is arranged on one side of the fixed seat 1, and a plurality of comb blades 3 are respectively arranged on one side of the comb seat 2. A plurality of jacquard yarn guide needles 4 are respectively arranged on the lower sides of a plurality of comb blades 3. A plurality of blocking teeth 7 are arranged on one side of the lower end of the comb seat 2, and the jacquard yarn guide needle 4 is arranged between two adjacent blocking teeth 7.

[0026] Specifically, in the present embodiment, when it is necessary to block and protect the yarn, the rotating plate 9 is rotated backward so that the rotating plate 9 drives the several protective tooth plates 11 to rotate backward. At the same time, when the rotating plate 9 is rotated backward, the fixing of the rotating plate 9 by the second buckle assembly 24 will be released. Then, when the rotating plate 9 is fitted with the baffle plate 5, the rotating plate 9 can be fixed by the first buckle assembly 23. Then, by placing several yarns between the corresponding several protective tooth plates 11, the yarns are guided and blocked in the gaps of the several protective tooth plates 11, thereby preventing the yarns from falling into the gaps between the jacquard needles during movement and causing yarn breakage, and avoiding the wear of the jacquard needle plate by the yarns. When it is necessary to protect the jacquard guide needle 4, the above steps are performed in reverse so that the rotating plate 9 drives the several protective tooth plates 11 to rotate, and the lower ends of the several jacquard guide needles 4 are respectively located in the gaps between the several protective tooth plates 11, so that the protective tooth plates 11 protect the jacquard guide needles 4.

[0027] The utility model provides a folding piezoelectric jacquard comb, wherein a first buckle assembly 23 includes a first clamping block 10 and a first U-shaped block 12, wherein the first clamping block 10 is fixedly mounted on one side of a rotating plate 9, and the first U-shaped block 12 is fixedly mounted on one side of a baffle 5, wherein the first clamping block 10 corresponds to the first U-shaped block 12, and both sides of the inner wall of the first U-shaped block 12 are provided with mounting grooves 19, and a first clamping bead 21 is slidably mounted in the mounting groove 19, and a first spring 20 is arranged between the first clamping bead 21 and the mounting groove 19, and both sides of the first clamping block 10 are provided with first arc-shaped clamping grooves 22, and the first clamping bead 21 corresponds to the first arc-shaped clamping grooves 22, and a notch 8 is arranged on one side of the baffle 5, The first U-shaped block 12 is located on one side of the slot 8, and the first U-shaped block 12 corresponds to the slot 8.

Second arc-shaped clamping grooves 18 are arranged on both sides of the second U-shaped block 13, and the second clamping bead 17 corresponds to the second arc-shaped clamping groove 18.

[0028] In another embodiment provided by the utility model, when the rotating plate 9 is rotated backward, the rotating plate 9 is rotated by pulling the rotating plate 9 with force, so that the rotating plate 9 drives the second clamping block 14 to rotate, and the second clamping block 14 will squeeze the two second clamping beads 17 when rotating, so that the two second clamping beads 17 will squeeze the second spring 16 under the squeezing force and shrink into the installation groove 15, thereby releasing the fixation of the rotating plate 9, and then when the rotating plate 9 is about to fit with one side of the baffle 5, the rotating plate 9 will drive the first clamping block 10 to first insert into the notch 8, and then insert into the first U-shaped block 12, and then the first clamping block 10 will The first clamping bead 21 is squeezed so that the first clamping bead 21 is squeezed against the first spring 20 by the squeezing force and retracts into the mounting groove 19. Then, when the first arc-shaped clamping groove 22 is aligned with the first clamping bead 21, the first clamping bead 21 is inserted into the first arc-shaped clamping groove 22 by the elastic force of the first spring 20, thereby fixing the first clamping block 10 and the rotating plate 9. Then, when the rotating plate 9 needs to be rotated forward, the above steps are reversed to release the fixation of the first clamping bead 21 to the first clamping block 10 and the rotating plate 9, and the second clamping bead 17 fixes the second clamping block 14 and the rotating plate 9.

[0029] Working principle: When the piezoelectric jacquard comb is used, the second buckle assembly 24 can be released from the fixing of the rotating plate 9, and the rotating plate 9 can be rotated backward so that the rotating plate 9 drives the several protective teeth 11 to rotate backward, and the rotating plate 9 can be fixed by the first buckle assembly 23, so that the several yarns are respectively placed between the corresponding several protective teeth 11, so as to avoid the yarns falling into the gaps between the jacquard needles during movement to cause yarn breakage and avoid the wear of the jacquard needle plate by the yarns.
