[0037] The weft knitting assembly is arranged in the middle of the machine base, and the first heald frame 180 and the second heald frame 190 are in transmission connection with the first transmission mechanism 110, which realizes compact structure. This design makes the whole loom model small in size, easy to carry and place, and suitable for teaching demonstration in the laboratory. The up-and-down alternating movement of the heald frame and the reciprocating movement of the shuttle 140 in the swing piece 130 are clear and visible, and students can directly observe these key actions, thereby more intuitively understanding the working principle of the textile machinery. The warp knitting assembly is arranged at the head of the machine base, including the swing piece 130 and the shuttle 140. The swing piece 130 is in transmission connection with the power assembly 100 through the second transmission mechanism 120 and performs a pendulum movement to introduce the warp. This design allows each mechanism to operate independently. The stable reciprocating movement of the swing piece 130 and the shuttle 140 effectively introduces the warp.

[0038] The second transmission mechanism 120 includes a crank linkage mechanism 200, which is in transmission connection with the swing piece 130 to drive the swing piece 130 to move towards or away from the weft knitting assembly. The design of the crank linkage mechanism 200 ensures that the swing piece 130 can perform precise pendulum movement, and the design of the crank linkage mechanism 200 is more concise, reducing the number of components and failure points.

When the second transmission mechanism 120 rotates, it drives the first eccentric wheel 250 and the second eccentric wheel 260 to rotate. This converts the continuous rotary motion provided by the power source into the required intermittent trigger action, reducing unnecessary energy waste. Compared with mechanisms that directly provide intermittent motion, this method is more efficient and can reduce energy consumption while ensuring work efficiency.

The design of the first reset member and the second reset member ensures that the first trigger block 150 and the second trigger block 160 can quickly and accurately return to the initial position after each time driving the shuttle 140 to reciprocate. This precise reset action ensures that the starting conditions of the next movement are consistent, improving the stability and repeatability of the loom model operation. The first reset member and the second reset member can use springs or rubber bands.

The 180° phase difference arrangement of the first eccentric block 230 and the second eccentric block 240 ensures that the first harness frame 180 and the second harness frame 190 can accurately move up and down alternately. This synchronous and symmetrical movement mode ensures the consistency and accuracy of the action of the harness during the weft knitting process, improving the quality of the fabric and the clarity of the pattern.
