Adjustable weft density plastic braiding machine

Abstract

This utility model discloses an adjustable weft density plastic knitting machine, including mounting plates on both sides, multiple support frames between the two mounting plates, and multiple equally spaced wire guides slidably connected between two adjacent support frames. Each wire guide has a positioning ring inside, and a thread-passing groove is formed on one side of each wire guide. An adjustment mechanism for adjusting the support frames is provided on one side of the mounting plate. This utility model, by setting multiple wire guides between the support frames for thread passing, allows for adjustment of the weft density, facilitating the adjustment of the number and position of the weft threads. It also facilitates the installation and removal of the weft threads. The adjusting frame drives a sliding abutment plate within the support frame, and the contact between the abutment plate and the wire guide is used to position and stabilize the wire guide, while also facilitating the positioning and support of multiple wire guides.

Description

Technical Field

[0001] This utility model relates to the field of plastic weaving machine technology, and in particular to an adjustable weft density plastic weaving machine. Background Technology

[0002] In the plastic weaving production process, weft density is a key factor affecting product quality and performance.

[0003] However, existing plastic weaving machines have many shortcomings in weft density adjustment. On the one hand, the weft density adjustment method of traditional plastic weaving machines is relatively complex and has limited precision. It usually requires replacing transmission components such as gears and sprockets of different specifications to adjust the weft density. This method is not only cumbersome to operate, requiring professional technicians to spend a lot of time on disassembly and installation, but also cannot achieve continuous and precise adjustment of weft density due to the limited specifications of replaceable parts, making it difficult to meet the market's demand for diverse weft density in plastic products. On the other hand, adjusting the weft density of existing plastic weaving machines often affects the overall operational stability of the equipment. The replacement of transmission components may lead to imbalance in the transmission system, which in turn causes problems such as increased equipment vibration and noise, affecting product quality and potentially shortening the service life of the equipment.

[0009] Preferably, one side of the support frame is fixedly connected to two symmetrically arranged support plates, and a support rod is fixedly connected between the two support plates. The support rod slides through and connects to multiple adjustment frames.

[0010] Preferably, the side wall of the support rod is threaded with a plurality of positioning nuts, and two of the positioning nuts are located on both sides of the adjustment frame.

[0020] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model.

Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0021] Reference Figure 1-4 An adjustable weft density plastic weaving machine includes mounting plates 1 on both sides. Two symmetrically arranged adjustment grooves 9 are opened on one side of the mounting plate 1. A mounting rod 10 is slidably connected through the adjustment groove 9. A pressure plate 12 is fixedly connected to the side wall of the mounting rod 10. A mounting nut 11 is threadedly connected to the side wall of the mounting rod 10. The mounting nut 11 abuts against the side wall of the mounting plate 1. Multiple support frames 2 are provided between the two mounting plates 1. Two symmetrically arranged support plates are fixedly connected to one side of the support frame 2. A support rod 16 is fixedly connected between the two support plates. Multiple positioning nuts 17 are threadedly connected to the side wall of the support rod 16. The two positioning nuts 17 are located on both sides of the adjustment frame 13. The support rod 16 is slidably connected through the multiple adjustment frames 13.

[0022] Multiple wire frames 4 are slidably connected between two adjacent support frames 2. The wire frame 4 is provided with a positioning ring 6. A wire groove 5 is opened on one side of the wire frame 4. An adjustment mechanism for adjusting the support frame 2 is provided on one side of the mounting plate 1. The adjustment mechanism includes an adjustment rod 7 that is threaded through and connected to multiple support frames 2. A limit frame 8 is fixedly connected to one side of the mounting plate 1. Multiple support frames 2 are slidably connected in the limit frame 8.

[0023] The support frame 2 is provided with a propulsion mechanism for advancing the conductor frame 4. The propulsion mechanism includes a connecting groove on one side of the support frame 2.

Through the staggered distribution of multiple wire frames 4 and the pressing to keep them at the same horizontal position, the weft threads can be positioned and the density adjusted. Then, the positioning nut 17 fixes the support rod 16.
