Description

Technical Field

[0001] This invention relates to the technical field of crochet machines, and more particularly to a weft needle plate structure for a crochet machine. Prior Technology

[0002] The commonly known weft needle plate structure of a crochet machine, such as the approved new utility model announcement number M578707 "General Purpose Needle Plate Structure", is characterized by a needle plate being integrated with a weft drive device. The weft drive device has a first spindle on each side of the machine face inward, and a connecting block is fixed at the end of each first spindle. The connecting block connects the two ends of the needle plate. The cross-section of the needle plate is a long rectangle, used to position multiple weft needles. When the crochet machine is in operation, the needle plate can be driven by the weft drive device, which drives the weft needles to perform the crochet operation.

[0003] With the increasing popularity of crochet technology and the decreasing prices of knitted garments and other finished products, manufacturing costs have become an important issue for manufacturers. Increasing the width of crochet machines and crocheting larger areas of fabric is one way to reduce manufacturing costs.

[0004] The aforementioned needle plate structure is characterized by a long rectangular cross-section. Therefore, when the length of the needle plate is increased, the needle plate is prone to compressive stress during high-speed knitting operations, which can lead to wobbling or even deformation of the needle plate. The deformation is particularly severe in the central position, resulting in problems such as the production of defective products during knitting.

[0005] In addition, since the first spindle of the weft drive device needs to be pre-assembled with the connecting block and then with the needle plate, the assembly becomes more inconvenient. Summary of the Invention

[0006] The inventors of this invention have made improvements to the conventional crochet machine's weft needle plate structure, which is still considered to have insufficient strength and is prone to deformation in actual use.

[0007] The main objective of this invention is to provide a weft needle plate structure for a crochet machine, which can increase overall strength by setting the cross-section of the weft needle plate in an L-shape. This effectively prevents shaking while increasing production speed, and provides a simpler, faster, and more secure way to assemble the weft needle plate. This achieves increased product output and improved fabric yield under wide needle plate operation.

[0008] In order to achieve the aforementioned objective, the present invention provides a weft needle plate structure for a crochet machine, which is installed between two crochet machine crochet seats. Each of the two crochet seats is provided with a spindle, which is a first spindle and a second spindle. Each spindle includes a weft needle plate. The weft needle plate has an L-shaped cross-section to form a vertical section and a horizontal section. The two ends of the horizontal section of the weft needle plate are provided with a shaft hole along the axial direction, and the two shaft holes are respectively used for the first spindle and the second spindle to be fitted and fixed.

[0009] In one embodiment of the present invention, the weft needle plate structure of the above-mentioned crochet machine has a groove along the axial direction relative to the two shaft holes. The groove is connected to the shaft holes, and a plurality of positioning holes are provided through the horizontal section of the groove. The positioning holes are located at positions different from the shaft holes. A plurality of fixing members are provided, which are located in the positioning holes of the weft needle plate. The fixing members reduce the gap between the two grooves of the weft needle plate to reduce the diameter of the two shaft holes and clamp the first mandrel and the second mandrel respectively.

[0010] In one embodiment of the present invention, the weft needle plate structure of the above-mentioned crochet machine is provided with three positioning holes at each end of the weft needle plate.

[0011] In one embodiment of the present invention, the weft needle plate structure of the above-mentioned crochet machine has the positioning holes being screw holes and the fixing members being bolts.

[0012] In one embodiment of the present invention, the weft needle plate structure of the above-mentioned crochet machine has a limiting groove recessed along the axial direction at the position of the vertical section of the weft needle plate adjacent to the horizontal section.

[0013] In one embodiment of the present invention, the weft needle plate structure of the above-mentioned crochet machine further includes a plurality of weft needles, one end of which forms a clamping section and the other end forms an extension section. The clamping section forms a hook-shaped clamping part on the vertical section of the weft needle plate, and a positioning part protrudes from the end of the clamping section of the weft needles. Each positioning part of the weft needles is respectively engaged with the limiting groove of the weft needle plate.

[0014] In one embodiment of the present invention, the weft needle plate structure of the above-mentioned crochet machine has a plurality of needle grooves longitudinally recessed on the other side of the weft needle plate, which is different from the limiting groove, and the extensions of the weft needles are respectively fitted into each needle groove of the weft needle plate.

[0020] As shown in Figures 1 to 4, the weft needle plate structure of the crochet machine of the present invention is used to be installed between two crochet machine ...

[0021] The weft needle plate 20 has an L-shaped cross-section, forming a vertical section 21 and a horizontal section 22. Each end of the horizontal section 22 of the weft needle plate 20 has an axially oriented shaft hole 23. The two shaft holes 23 are respectively used for the insertion of the first spindle 12 of the weft yarn transmission mechanism 11 and the second spindle of the weft yarn linkage mechanism 13. The weft needle plate 20 has an axially oriented groove 24 relative to the positions of the two shaft holes 23. The groove 24 communicates with the shaft holes 23. The horizontal section 22 passes through the groove 24 and is provided with a plurality of positioning holes 25. As shown in the figure, there are three positioning holes 25 at each end of the weft needle plate 20, and each of them is a screw hole. The position of the positioning holes 25 is different from the position of the shaft hole 23. The vertical section 21 of the weft needle plate 20 is provided with a limiting groove 26 along the axial direction at the position adjacent to the horizontal section 22. The other side of the weft needle plate 20, which is different from the limiting groove 26, is provided with a plurality of needle grooves (not labeled in the figure) longitudinally recessed.

[0022] These fasteners 30 are disposed in each of the positioning holes 25 of the weft needle plate 20. The gap between the two grooves 24 of the weft needle plate 20 is reduced by these fasteners 30, so as to reduce the diameter of the two shaft holes 23, and respectively clamp the first spindle 12 of the weft transmission mechanism 11 and the second spindle of the weft linkage mechanism 13. As shown in the figure, these fasteners 30 in this embodiment are bolts.

[0023] One section of the weft needles 40 forms a clamping section 41, and the other section forms an extension section 42. The clamping section 41 forms a hook and clamps the vertical section 21 of the weft needle plate 20. The end of the clamping section of the weft needles 40 is provided with a positioning part 410. Each positioning part 410 of the weft needles 40 is respectively engaged with the limiting groove 26 of the weft needle plate 20. The extension section 42 of the weft needles 40 is respectively embedded in each needle groove of the weft needle plate 20, thereby positioning the weft needles 40 on the weft needle plate 20.

[0024] By designing the transverse cross-section of the weft needle plate 20 in this embodiment as L-shaped, the cross-sectional thickness of the horizontal section 22 is greater than that of the vertical section 21, which can effectively strengthen the overall strength of the weft needle plate 20. This reduces the deformation problem when the axial direction of the weft needle plate 20 is set longer under the requirement of wide-width crochet, and improves the yield of fabrics under crochet operations.

[0025] Meanwhile, by combining the weft needle plate 20 with the first spindle 12 of the weft transmission mechanism 11 and the second spindle of the weft linkage mechanism 13 in this embodiment, that is, by utilizing the two shaft holes 23 of the weft needle plate 20, in conjunction with the two grooves 24 and the fixing parts 30, the purpose of convenient use and replacement of the weft needle plate 20 can be achieved, thereby improving the efficiency of crochet operations.

[0026] The present invention has been described by way of the above embodiments and variations. All embodiments and variations of the present invention are merely illustrative. Based on the essential spirit and scope of the present invention, various variations of the weft needle plate structure of the crochet machine that include the above features are covered by the present invention.
