Description

Technical Field

[0001] This utility model relates to the field of weaving machine technology, specifically a modular quick-change needle device for weaving machines. Background Technology

[0002] The loom, also known as a spinning machine, weaving machine, or cotton spinning machine, was originally a human-powered loom. In the development of modern textile industry, various types of shuttleless looms have emerged, including rapier looms, projectile looms, air-jet looms, water-jet looms, multiphase looms, and magnetic weft-introducing looms. Compared to shuttle looms, shuttleless looms produce fabrics with unparalleled advantages in terms of output, quality, and variety, and have replaced shuttle looms in most weaving fields.

[0003] After a period of use, the needles of existing looms will be damaged. When traditional needles are damaged, replacement requires manual inspection one by one. Factors such as space and lighting on the loom severely limit the inspection speed of maintenance personnel, making it difficult to find the corresponding needle for replacement. This process takes up to several hours and depends on skilled workers, which affects the production efficiency of the loom. Utility Model Content

[0004] The purpose of this invention is to provide a modular quick-change needle device for a loom, so as to solve the problems mentioned in the background art.

[0006] The needle plates are L-shaped, and the needle plates on both sides do not have mounting slots. The two ends of the spring are fixed to the needle plates on both sides respectively.

[0007] With the above structure, several needle plates are L-shaped to facilitate the installation of module components, and springs can limit the movement of the module components. Several needle plates are equipped with upper and lower insert knitting.

[0008] The module assembly includes a pressure plate and a pressing plate. The pressing plate is attached to the needle plate and the pressure plate and the pressing plate are rotatably connected. A pressing block is fixed on the inner side of the pressure plate. The pressing block is trapezoidal. Two slots and two grooves are opened on the inner side of the pressure plate. The slots and grooves are connected internally.

[0009] With the above structure, the pressure plate and the pressing plate can be engaged to limit the forward and backward movement of the knitting needle, while the pressing block can limit the up and down movement of the knitting needle.

[0010] The inner side of the pressing plate is fixed with several evenly distributed limiting plates, and the limiting plates on both sides are fixed with limiting blocks, and the upper part of the limiting blocks is fixed with protrusions.

[0011] With the above structure, several evenly distributed limiting plates can limit the left and right directions of the knitting needles. The limiting blocks and protrusions cooperate to be snapped onto the pressure plate.

[0012] The limiting block is located inside the slot, and the protrusion is located inside the groove.

[0013] With the above structure, the limiting block and the protrusion cooperate to be engaged inside the slot and groove, thereby engaging with the pressure plate.

[0014] The module component also includes several knitting needles, which are placed between adjacent limiting plates. Each of the knitting needles has a limiting groove above it, which is trapezoidal, and the pressing block presses onto the limiting groove.

[0015] With the above structure, the pressing block is pressed onto the limiting groove. The limiting groove and the pressing block are trapezoidal, which can limit the vertical movement of the knitting needle.

[0016] Compared with the prior art, the beneficial effects of this utility model are: A modular quick-change needle device for a loom, through the cooperation of the needle bed assembly 2 and the module assembly of the flat knitting machine, allows for the removal of the corresponding module and replacement of a new module when a needle is damaged, without the need for individual inspection. Afterwards, the module with the damaged needle is moved to a workbench for easy operation, where the needles are inspected one by one to remove the damaged needle and replace it with a new one. This eliminates the need for maintenance personnel to inspect each needle individually in the confined space of the loom, thus improving the speed of needle replacement and reducing the impact on production.

[0019] 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.

[0020] like Figures 1-3 As shown, this utility model provides a technical solution: a modular quick-change needle device for a weaving machine, including a needle bed assembly 2 of a flat knitting machine, a plurality of needle beds 5 are arranged above the needle bed assembly 2 of the flat knitting machine, a plurality of needle plates 6 are fixed above the needle beds 5, needle grooves 15 are provided between the plurality of needle plates 6, a modular assembly is arranged inside the needle grooves 15, and mounting grooves 4 are opened on the sides of the plurality of needle plates 6, and springs 3 are arranged inside the mounting grooves 4.

[0021] Several needle plates 6 are L-shaped, and the needle plates 6 on both sides are not provided with mounting slots 4. The two ends of the spring 3 are respectively fixed on the needle plates 6 on both sides. The L-shaped needle plates 6 facilitate the installation of module components. The spring 3 can limit the position of the module components. The needle plates 6 are provided with upper and lower weft wefts.

[0022] The module assembly includes a pressure plate 7 and a pressing plate 8. The pressing plate 8 is attached to the needle plate 6 and the pressure plate 7 and the pressing plate 8 are rotatably connected. A pressing block 13 is fixed on the inner side of the pressure plate 7. The pressing block 13 is trapezoidal. Two slots 14 and two grooves are opened on the inner side of the pressure plate 7. The slots 14 and the grooves are connected to each other. The pressure plate 7 and the pressing plate 8 can be engaged to limit the front and back direction of the knitting needle 1. The pressing block 13 can limit the up and down direction of the knitting needle 1.

[0023] Several evenly distributed limiting plates 11 are fixed on the inner side of the pressing plate 8. Limiting blocks 10 are fixed on the limiting plates 11 on both sides. A protrusion 12 is fixed above the limiting block 10. The several evenly distributed limiting plates 11 can limit the left and right directions of the knitting needle 1. The limiting block 10 and the protrusion 12 cooperate to be snapped onto the pressing plate 7.
