Description

Technical Field

[0001] The utility model relates to the technical field of dust removal devices, in particular to a dust removal device for a circular loom used in the production of plastic woven bags. Background Art

[0002] A plastic woven bag knitting machine is a device used for producing plastic woven bags and is mainly applied to the packaging industry. It can weave plastic flat filaments into various specifications of woven bags, such as cement bags, fertilizer bags, grain bags, etc. A circular loom is a key device for producing plastic woven bags. In the production process of plastic woven bags, the circular loom plays a crucial role, and its performance directly affects the output and quality of the woven bags.

[0003] The prior art discloses a low-power automatic circular weaving device for woven bags with the application number: 202220908507.7, which includes a wire reel, a mounting frame, a circular loom, and a collecting roller. The circular loom is installed at the central position inside the mounting frame. The top of the mounting frame is fixedly connected with a top plate, and the upper surface of the top plate is fixedly connected with a bag knitting device. The output end of the bag knitting device is connected with a woven bag. The right side wall of the mounting frame is fixedly connected with a positioning frame, and sliding grooves are opened on both the left and right side walls of the positioning frame. In the utility model, through the provided positioning frame with adjustable tension, according to the different tensions required by different weaving raw threads, the height of the rotating shaft in the positioning frame is adjusted to prevent the phenomenon that the collected woven bags are prone to winding and knotting. Through the cooperation among the bag knitting device, the positioning roller, and the collecting roller, the processed woven bags can be wound around the collecting roller. Before being collected by the collecting roller, the woven bags are ironed by a heat setting roller heated by electricity, so that the finished woven bags are formed at one time, improving the processing efficiency. However, the prior art still has the problem that a large amount of dust and debris are generated during the production of plastic woven bags by the circular loom, and the debris and dust fill the entire operation workshop during the production process. These debris and dust will cause great impacts on the bodies of users and operators, and the adhesion of the debris to the surface of the woven bags will also affect the quality of the finished products. For this reason, we propose a dust removal device for a circular loom used in the production of plastic woven bags to solve the above problems. Summary of the Utility Model

[0004] Aiming at the deficiencies existing in the above problems, the utility model provides a dust removal device for a circular loom used in the production of plastic woven bags, which can effectively clean the debris and dust on the surface of the woven bags, greatly improve the product quality, and enhance the ability to clean the dust inside the machine frame.

[0005] In order to solve the above problems, the technical solution provided by the utility model is as follows:

[0006] A dust removal device for a circular loom used in plastic woven bag production, comprising a table board, a frame and a circular loom body. Legs are fixedly installed at the lower end of the table board, and a cross beam is fixedly installed between the left and right legs. A conveying roller is installed at the upper end of the frame. A brush roller is arranged above the circular loom body, and the brush roller is arranged directly below the conveying roller. A dust suction cylinder is arranged outside the brush roller. The dust suction cylinder is communicated with a first dust collection box through a first connecting pipe, and a first air suction fan is installed at the first connecting pipe. A dust suction hood is arranged below the circular loom body, and the dust suction hood is communicated with a second dust collection box through a telescopic hose and a second connecting pipe, and a second air suction fan is installed at the second connecting pipe.

[0007] Further, the number of the dust suction hoods is two, and the two dust suction hoods are symmetrically arranged on the front and rear sides of the circular loom body.

[0008] Further, a telescopic push rod is fixedly installed at the upper end of the table board, and the output end of the telescopic push rod is fixedly connected to the outer wall of the dust suction hood.

[0009] Further, the second dust collection box is installed at the upper end of the cross beam.

[0010] Compared with the prior art, the utility model has the following advantages:

[0011] 1. Through the first air suction fan, the dust on the woven bag and the debris brushed off by the brush roller are sucked into the first connecting pipe and enter the first dust collection box for collection, with a higher dust removal effect, avoiding the problem that the debris adhering to the surface of the plastic woven bag finished product affects its quality.

[0012] 2. When the second air suction fan is started, the dust in the frame can be sucked through the dust suction hood, and then enters the second dust collection box through the second connecting pipe for collection, further improving the dust removal effect in the frame.

[0013] 3. The output end of the telescopic push rod is fixedly connected to the outer wall of the dust suction hood. By pushing the dust suction hood up and down through the telescopic push rod to adjust the height of the dust suction hood, it can be adjusted to a more suitable position according to the actual dust suction requirement, so as to more accurately capture pollutants such as dust and dirt, and improve the dust suction efficiency.

[0014] In summary, the dust removal device for the circular loom used in plastic woven bag production has wide practicability to solve the problems in the above-mentioned background technology that in the prior art, a large amount of dust and debris are generated during the production of plastic woven bags by the circular loom, and the debris and dust fill the entire operation workshop during the production process, which will cause great impact on the bodies of users and operators, and the debris adhering to the surface of the woven bag will also affect the quality of the finished product.
