Description

Technical Field

[0001] This invention relates to a lawn machine for producing artificial turf, specifically to a flocking jacquard device in the lawn machine, belonging to the field of textile equipment technology. Background Technology

[0002] Existing artificial turf production machines, such as the one disclosed in Chinese Utility Model Patent ZL202120975892.2 entitled "A Tufting Machine for Artificial Turf Production," include a frame, a support plate, needle holders, needles, a main hook base, a main hook blade, a secondary hook base, and secondary hook blades. The support plate is mounted on the frame, and the needle holders are arranged parallel to and directly above the support plate. Multiple needles are fixed at equal intervals on the side of the needle holders near the support plate. The support plate has multiple holes corresponding to the needle positions for the needles to pass through. The secondary hook base is located below the support plate, and the number of secondary hook blades is the same as the number of needles and they are fixed at equal intervals. On the side of the auxiliary hook base near the support plate, the main hook base is arranged parallel to the bottom of the support plate. There are multiple main hook knives that match the auxiliary hook knives. The main hook knives are fixed on the side of the main hook base near the auxiliary hook base. The tufting machine also includes a needle seat drive mechanism that drives the support plate to move up and down, thereby causing the needle to move up and down along the holes of the support plate; a main hook drive mechanism that drives the main hook base to move back and forth, thereby causing the main hook knives to pick up or release thread from the needle; a secondary hook drive mechanism that drives the auxiliary hook base to move back and forth, thereby causing the auxiliary hook knives to pick up or release thread from the main hook knives; and a main drive mechanism that drives the needle seat drive mechanism, the main hook drive mechanism, and the auxiliary hook drive mechanism to work together. The existing tufting machine, also known as a lawn machine, has the following disadvantages in actual production: it can only produce rectangular strip lawn patterns or square block lawn patterns, and cannot produce different shapes such as rhombuses, hearts, or other self-designed lawn patterns. The variety of lawn patterns is limited, the effect is ordinary and lacks novelty, and it cannot meet the actual needs of users for multi-patterned lawns. Moreover, the existing lawn machine has a complex structure and high manufacturing cost. Summary of the Invention

For example, the third drive mechanism 8 includes a first linear motor with a lead screw and nut linear motion mechanism. During installation, the first linear motor is fixedly connected to the first output shaft 3-8 or the first guide rail 3-9 through a connecting plate and bolts. The nut in the first linear motor is fixedly connected to the first needle bed 1. When the first linear motor is working, its nut drives the first needle bed 1 to make independent reciprocating lateral movement along the width of the lawnmower (not shown in the figure). The fourth drive mechanism 9 can also adopt other structures. For example, the fourth drive mechanism 9 includes a second linear motor with a lead screw and nut linear motion mechanism. During installation, the second linear motor is fixedly connected to the second output shaft 4-8 or the second guide rail 4-9 through a connecting plate and bolts. The nut in the second linear motor is fixedly connected to the second needle bed 2.

Dovetail-shaped grooves, arc-shaped grooves, triangular grooves, trapezoidal grooves, or rectangular grooves are correspondingly set on both sides of the first guide rail 3-9 and the second guide rail 4-9, and the protrusions can slide in the corresponding grooves.

[0035] As a preferred embodiment of the present invention, such as Figure 13 The diamond-shaped turf pattern shown has a distance of W between two adjacent grass yarns 11 in the longitudinal direction of the artificial turf, where W is one stitch pitch. The distance between the tufted needles 7 on two adjacent first needle holders 5 of the first needle bed 1 is n × W, where n is an integer greater than or equal to 3, i.e., greater than or equal to 3 stitch pitches. The distance between the tufted needles 7 on two adjacent second needle holders 6 of the second needle bed 2 is also n × W, where n is an integer greater than or equal to 3, i.e., greater than or equal to 3 stitch pitches. In actual operation, the distance between the tufted needles 7 on two adjacent first needle holders 5 can be adjusted accordingly, for example, to 5, 8, or 12 stitch pitches, etc., and the distance between the tufted needles 7 on two adjacent second needle holders 6 can also be adjusted accordingly, for example, to 5, 8, or 12 stitch pitches, etc., making operation very convenient.

Figure 8 The fabric 24 is pulled from the rear to the front of the machine by the fork 25 of the lawnmower. The fork 25 of the present invention can also be replaced by a traction roller. The fabric 24 is pulled from the rear to the front of the machine by the traction roller (not shown in the figure). The tufting needles 7 on the first needle bed 1 and the first needle seat 5 are driven by the third drive mechanism 8, and the tufting needles 7 on the second needle bed 2 and the second needle seat 6 are driven by the fourth drive mechanism 9. They move laterally at a set distance or stitch pitch, or move laterally laterally individually or alternately to the flocking position. The first needle bed 1 is driven by the first drive mechanism 3, and the second needle bed 2 is driven by the second drive mechanism 4. They move up and down in the vertical direction simultaneously or individually or alternately to flock the fabric 24. In the continuous operation of the fork traction, needle bed lateral movement and up and down movement flocking, different shapes of rhombus, heart, triangle, T or other self-designed lawn patterns or shapes and different colors of lawn products can be realized. Figure 13 Only diamond-shaped lawn patterns are shown; other lawn patterns are not shown.

[0037] After trial use, this invention can produce lawn products of different shapes, such as rhombuses, hearts, triangles, T-shapes, L-shapes, or other self-designed lawn patterns or shapes, and different colors. It can better meet users' needs for multi-patterned and fancy lawns. Moreover, it has a simple structure, is easy to implement, and has low manufacturing costs, achieving good results.
