Description

Technical Field

[0001] This utility model relates to the field of knitting machine equipment, specifically to a multi-head direct-drive knitting machine transmission mechanism. Background Technology

[0002] Currently, braiding machines produce multiple different styles of ropes and straps on a single machine. Each rope or strap requires a set (head) of braiding components. High-efficiency braiding machines are designed with multiple braiding sets (heads). Conventional braiding machines have two ends (such as...) Figure 5 (or multiple heads running in the same direction) One or two transition gears 7 need to be installed between adjacent heads to ensure that the weaving components of each head of the adjacent weaving machine have a certain gap between them, so that the running track groove of the spindle will not cause running interference problems. At the same time, the more transition gears 7 there are, the greater the energy consumption and the greater the noise. Moreover, the addition of intermediate transition gears 7 increases the installation space and the size of the overall equipment. The more weaving heads the weaving machine has, the more transition gears are needed, resulting in a larger overall equipment size, higher cost, inconvenience in transportation and installation, and a larger space occupation. Summary of the Invention

[0003] To solve the above-mentioned technical problems, this utility model proposes a multi-head direct-drive braiding machine transmission mechanism, which is ingeniously designed, has a reasonable and compact structure, small size, low energy consumption, and low noise.

[0004] The technical solution of this utility model:

[0005] The multi-head direct-drive knitting machine transmission mechanism includes a drive unit and at least two knitting drive units. The drive unit drives and connects to any one of the knitting drive units. The two knitting drive units are driven and transmitted through the meshing of the two nearest adjacent gears. The forks of the dial connected above the two adjacent meshing gears are installed at a certain angle with their forks staggered. A non-crossing arc guide block is designed and installed at the intersection of the two knitting track path grooves on the outer side of the dial. The non-crossing arc guide block is designed with two non-crossing arc guide grooves. The two ends of each arc guide groove are connected to the knitting track path groove on the corresponding side.

[0006] The drive unit includes a drive motor, which drives a gear or gear shaft connected to either end of the braiding transmission unit.

[0007] Each knitting drive unit includes several gears arranged in a circle with adjacent gears meshing together. Each gear is mounted on the underside of the main board of the knitting machine via a gear shaft. The upper end of the gear shaft passes through the main board and a dial is mounted on the upper end of the gear shaft. The dial has multiple forks around its circumference to drive the spindle.

[0008] The specified angle is 90 degrees.

[0009] The advantages of this utility model are its ingenious design, reasonable and compact structure, no need for transitional gear drive connection, small size, low energy consumption, and low noise; the non-crossing circular arc guide block design avoids interference between the spindle and adjacent dials when the spindle moves, and the two closest adjacent dials are staggered at a certain angle, the gear meshing and running directions are opposite, continuous operation, the spindles always run alternately, and no collision will occur.

[0015] See attached document Figure 1-4 The multi-head direct-drive knitting machine transmission mechanism includes a drive unit and at least two knitting drive units. The drive unit drives and connects to any one of the knitting drive units. The two knitting drive units are connected by meshing gears 1, which are adjacent to each other. The forks 21 of the dial 2 connected above the two meshing gears 1 are installed at a certain angle. A non-crossing arc guide block 3 is designed and installed at the intersection of the two knitting track path grooves on the outer side of the dial 2. The non-crossing arc guide block 3 is designed with two non-crossing arc guide grooves 31, and the two ends of each arc guide groove 31 are connected to the knitting track path groove on the corresponding side. The certain angle is 90 degrees.

[0016] The drive unit includes a drive motor, which drives a gear 1 or gear shaft 4 connected to either end of the braiding transmission unit. The drive motor can drive the connected gear through a transmission method such as a belt or gears.

[0017] Each knitting drive unit includes several gears 1, which are arranged in a circular shape and mesh with each other. Each gear 1 is rotatably mounted on the main board 6 of the knitting machine via a gear shaft 4. The upper end of the gear shaft 4 passes through the main board 6 and a dial 2 is mounted on the upper end of the gear shaft 4. The dial 2 is designed with multiple forks 21 around its circumference to drive the spindle 5 to move.

[0018] In use, the spinning machine spindles weave fabric via gear meshing, with the spindles moving in the same direction as the gears. Above the gears, a dial with evenly distributed notches (forks) is installed. Between the dial and the gears, there is a track path groove with the same spacing as the gears. The spindles move by being propelled by the notches on the dial, and the track path groove controls the spindle's trajectory. The gear meshing directions are all opposite. When two adjacent dials are used, the spindles installed are staggered and run continuously. The spindles always alternate, and the spindles rotating in opposite directions will not collide or interfere. This invention relies on the principle of opposing gear meshing rotation directions, reducing the design and installation of transition gears. A non-crossing arc guide block added to the track path groove on the panel is sufficient to achieve the linkage effect at both ends. The more transmission gears there are, the greater the energy consumption and noise. This invention reduces multiple transition gears, significantly reducing noise and energy consumption. Direct connection at both ends results in a compact machine, reducing the equipment's footprint and improving its dynamic performance. The two-end direct connection method relies on the non-crossing arc guide block on the main board to separate the running directions of the two spindles; the same direct connection method can directly connect multiple numbers of braiding heads, or they can be directly connected to each other at different angles. This utility model is also applicable to braiding machines of different sizes and models (diameter of the dial).
