Abstract
Description
Technical Field
[0001] The utility model relates to a tufting machine for producing artificial turf, carpets, blankets, etc., in particular to a needle bed used on a tufting machine, belonging to the technical field of textile equipment. Background Art
[0002] Existing tufting machines for producing artificial turf, carpets, blankets, etc., especially those for producing artificial turf, all adopt a single needle bed, and tufting yarns or grass filaments on a base fabric or backing fabric through tufting needles installed on the bottom surface of the needle bed. In the formed products, the yarns or grass filaments are all of the same color. If the product requires two-color yarns or grass filaments, that is, to form a two-color effect, it is necessary to first uniformly tuft one color of yarns or grass filaments on a base fabric or backing fabric on one tufting machine, and then go to another tufting machine to tuft another color of yarns or grass filaments. That is, to form a two-color effect, secondary processing is required, and it can only be completed by tufting another color of yarns or grass filaments again. This results in low production efficiency and high production cost of the products. Summary of the Invention
[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a needle bed for a two-color tufting machine that can implant two-color yarns or grass filaments on a base fabric or backing fabric by only using one tufting machine, thereby forming a product with a two-color effect, which can greatly improve production efficiency and reduce production cost.
[0004] To solve the above technical problem, the utility model adopts such a needle bed for a two-color tufting machine, which includes a horizontally arranged first needle bed and a second needle bed, and vertically arranged tufting needles. The first needle bed includes a first substrate, and a plurality of first convex teeth and first grooves arranged at intervals are provided on one side surface of the first substrate. The second needle bed includes a second substrate, and a plurality of second convex teeth and second grooves arranged at intervals are provided on one side surface of the second substrate. The first convex teeth of the first substrate are embedded in the second grooves of the second substrate, and the second convex teeth of the second substrate are embedded in the first grooves of the first substrate. The tufting needles are vertically installed on the first convex teeth and the second convex teeth, and the tufting needles installed on the first convex teeth and the tufting needles installed on the second convex teeth are on the same horizontal line.
[0005] As a preferred embodiment of the utility model, the distance between the tufting needles installed on the first convex teeth is one needle pitch, and the distance between the tufting needles installed on the first convex teeth and the tufting needles installed on the second convex teeth is half a needle pitch.
[0006] As a preferred embodiment of the present utility model, vertical first positioning holes and second positioning holes are respectively formed on the first convex teeth and the second convex teeth, and the upper needle bodies of the tufting needles are inserted into the first positioning holes and the second positioning holes and fixed by set screws.
[0007] As a preferred embodiment of the present utility model, the first convex teeth and the second grooves are adapted in size and shape, and the second convex teeth and the first grooves are adapted in size and shape.
[0008] As a preferred embodiment of the present utility model, the cross-sectional shapes of the first convex teeth, the second convex teeth, the first grooves and the second grooves are rectangular, triangular, trapezoidal or dovetail-shaped.
[0009] After adopting the above structure, the present utility model has the following beneficial effects:
[0010] The needle bed of the tufting machine of the present utility model is composed of a first needle bed and a second needle bed nested with each other. During operation, only the first color of yarn or grass filaments are threaded into the tufting needles of the first needle bed, and at the same time, the second color of yarn or grass filaments are threaded into the tufting needles of the second needle bed. The first color of yarn or grass filaments are implanted on the base fabric or the bottom fabric by the up and down movement of the first needle bed. After the implantation is completed, the second needle bed is horizontally shifted to the working position of the first needle bed, preferably by half a needle pitch. The second color of yarn or grass filaments are implanted on the base fabric or the bottom fabric by the up and down movement of the second needle bed to form a two-color effect, so that the completed product has both the first color and the second color of yarn or grass filaments at the same time. The present utility model greatly improves the production efficiency and reduces the production cost.
[0011] The present utility model can complete products with a two-color effect by using only one tufting machine, greatly reducing the manufacturing cost of the products, and having a simple structure and being convenient to manufacture. Description of the Drawings
