Description

Technical Field

[0001] This utility model relates to the field of plastic woven bag production technology, specifically a circular loom for plastic woven bags. Background Technology

[0002] A circular loom for plastic woven bags is a specialized machine for producing plastic woven bags. It uses the principle of circular motion to weave flat plastic filaments, such as polypropylene or polyethylene, into circular woven fabric using a specific weaving method, which is then processed into plastic woven bags. The prepared plastic flat filaments are introduced into the weaving area of ​​the circular loom through a guide device. On the circular loom, the flat filaments are separated into warp and weft yarns. The warp yarns are drawn out through a warp beam, while the weft yarns are introduced through a shuttle or other weft insertion device. The warp and weft yarns interweave in the weaving area to form a circular woven fabric.

[0003] Chinese utility model patent CN217174001U discloses an automatic circular knitting machine for plastic woven bags, including a circular knitting machine base frame. A circular knitting machine body is fixedly connected to the top of the base frame. A material roller frame is placed on the side of the circular knitting machine body. A sealing door is movably connected to the front of the circular knitting machine body via a hinge. A horizontal plate is fixedly connected to the side of the inner wall of the circular knitting machine body. A groove is formed on the surface of the horizontal plate, and a fixing plate is fixedly connected to the surface of the inner wall of the groove. A short spring is fixedly connected to one end of the fixing plate. This utility model, through the combination of the above structures, achieves increased dust prevention inside the circular knitting machine, as well as dust shaking and subsequent collection functions.

[0027] The dust removal assembly includes a lifting cylinder 5 fixedly installed on the top of the mounting plate 4. A lifting plate 6 is fixedly installed on the movable end of the lifting cylinder 5. A dust removal hood 7 is fixedly installed between the two lifting plates 6. An air blowing hole 8 is opened on the inner top wall of the dust removal hood 7, and an air extraction hole 9 is opened on the inner side wall of the dust removal hood 7.

[0028] Specifically, the lifting cylinder 5 drives the lifting plate 6 to move down, which in turn drives the dust cover 7 to cover the circular weaving device 2. High-pressure gas is injected into the upper cavity of the dust cover 7, and the high-pressure gas is blown out from the air blowing hole 8, blowing off the dust on the circular weaving device 2. A negative pressure is formed in the lower cavity of the dust cover 7, which draws off the blown-off dust from the air extraction hole 9.

[0029] Please see Figures 1 to 3 In this embodiment, a high-pressure air pipe 10 is fixedly installed on the top of the dust collector 7. The bottom end of the high-pressure air pipe 10 extends into the interior of the dust collector 7, and one end of the high-pressure air pipe 10 is connected to an external air compressor. High-pressure gas is introduced into the high-pressure air pipe 10 through the air compressor, and then introduced into the upper cavity of the dust collector 7 through the high-pressure air pipe 10.

[0030] The dust hood 7 has a suction hose 11 fixedly installed on one side, and an annular partition 12 fixedly installed on the inner wall of the dust hood 7. The suction hose 11 is connected to the space below the annular partition 12.

[0031] Secondly, a vacuum cleaner 13 is fixedly installed on the top of the mounting base 1, and the input end of the vacuum cleaner 13 is fixedly connected to one end of the vacuum hose 11. When the vacuum cleaner 13 is started, it communicates with the lower half cavity of the dust cover 7 through the vacuum hose 11, creating a negative pressure in the lower half cavity of the dust cover 7.

[0032] Please see Figure 1 and Figure 3 In this embodiment, a reinforcing crossbeam 14 is fixedly installed between the two supporting frames 3, and two first guide wheels 15 are rotatably installed on the inner side wall of the mounting base 1.

A drive motor 18 that drives the circular weaving device 2 is fixedly installed on the inner bottom of the mounting base 1.

[0035] Please see Figure 4 In this embodiment, the top of the dust cover 7 is provided with a circular through hole that is compatible with the woven bag, and the dust cover 7 is compatible with the circular weaving device 2.

[0036] Specifically, the warp yarns are guided to the circular weaving device 2 by the first guide wheel 15, and the weft yarns are guided to the circular weaving device 2 by the second guide wheel 16. They interweave with each other in the circular weaving device 2 to form a circular woven fabric. The woven fabric is then discharged through the circular through hole at the top of the dust removal hood 7 and discharged through the guide wheel 17.

[0037] The working principle of the above embodiment is as follows: When dust removal is required, the lifting cylinder 5 drives the lifting plate 6 to move down, which in turn drives the dust cover 7 to cover the circular weaving device 2. High-pressure gas is introduced into the upper half cavity of the dust cover 7, and the vacuum cleaner 13 is started. It connects to the lower half cavity of the dust cover 7 through the vacuum hose 11, forming a negative pressure in the lower half cavity of the dust cover 7 to remove the dust.

[0038] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions.
