Description

Technical Field

[0001] This utility model relates to the field of textile fabric processing, specifically a dust removal device for perforated fabric textile processing. Background Technology

[0002] Perforated fabrics, due to their unique structure, have numerous regular or irregular pores on their surface and interior. This makes them highly susceptible to absorbing and accumulating dust, lint, and fiber debris generated during the textile processing, cutting, and finishing stages. Especially during high-speed winding and shearing processes, these tiny impurities quickly penetrate and hide deep within the pores.

[0003] Existing cleaning technologies, such as traditional one-way planar cleaning methods, often struggle to effectively reach these hidden "dead corners." This can cause dust particles to detach and re-adhere to the fabric surface in subsequent processes, severely impacting the final appearance quality and feel of the fabric.

[0004] Currently, most dust removal devices on the market use a method of reciprocating vibration of the fabric, combined with a suction head located on the side of the housing for dust removal. This method is effective at removing dust from flat, non-porous fabric surfaces. However, its deep cleaning capability is inadequate when dealing with perforated fabrics. The fundamental reason is that simple planar vibration cannot cause sufficient deformation in the fabric, making it difficult to effectively dislodge the fine particles adhering to the inner walls of the pores, thus preventing the suction head from completely removing them. To achieve the required cleanliness, operators often need to repeatedly manually turn the fabric over or use a brush to beat it. This not only significantly reduces production efficiency and increases labor costs, but the rough physical contact can also easily damage and break the fibers around the pores, affecting fabric quality.

[0005] To address these issues, some high-end equipment employs more complex technical solutions, such as multi-directional blowing and suction systems or multi-axis electric tilting mechanisms, aiming to enhance the coverage and depth of cleaning. However, these solutions invariably rely on complex motors, sensor arrays, and sophisticated control systems. This directly results in high equipment costs, as well as high subsequent maintenance costs and failure rates, making it difficult for these advanced devices to be widely adopted and promoted in small and medium-sized fabric processing enterprises and low-cost production lines that prioritize cost control. Utility Model Content

[0006] The purpose of this invention is to overcome the above-mentioned defects of the prior art and provide a dust removal device for textile processing that has a novel structure, good dust removal effect, low cost, and can effectively perform deep cleaning of perforated fabrics.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A dust removal device for perforated fabric textile processing includes a base, a box installed on the upper side of the base, and a fabric passing through the box from bottom to top. A twisting component, an air jet component, and a dust suction component are arranged sequentially along the fabric's movement path.

[0009] The torsion assembly is one of the core components of this invention. Its design aims to simulate the effect of manual shaking by applying a gentle yet effective torsion and rubbing motion to the fabric, thereby "shaking out" dust and impurities hidden deep within the pores. The assembly includes a housing, within which a cylindrical cam is fixedly mounted. A drive motor is also fixed to the housing, and its output is connected to a torsion component. A fixed block is slidably mounted on the torsion component via a slider. A friction roller is rotatably mounted at one end of the fixed block, and the other end of the friction roller is connected to a drive unit. The drive unit has a clip that slidably connects to the cylindrical cam. Through this ingenious mechanical linkage design, when the drive motor operates, the torsion component drives the fixed block in a reciprocating motion. Simultaneously, guided by the cylindrical cam, the drive unit drives the friction roller to generate a specific motion trajectory. Specifically, there are two fixed blocks, and the fabric passes between these two friction rollers. Crucially, the two friction rollers can slide along the width of the fabric, and their motion phases are opposite. This counter-movement allows the two friction rollers to apply an alternating, "rubbing" torsional force to the fabric, causing a slight twisting deformation that effectively loosens and shakes out stubborn dust from the pores.

[0010] After the dust is shaken out, a subsequent air jet assembly blows it away. This assembly includes nozzles facing the fabric, which are symmetrically distributed about the fabric's axis of symmetry to ensure that the airflow acts evenly across the entire width of the fabric, thoroughly blowing away the loosened dust from the fabric surface and pores.

[0011] Finally, the dust collection assembly collects the blown-away dust. This assembly includes two suction rollers fixed inside a housing. Each roller has multiple through-holes on its surface and is connected to an air pump. When the fabric passes over the suction rollers, the powerful suction acts on the fabric through the through-holes, quickly drawing away suspended dust and impurities, completing the entire dust removal process.

[0012] As a further optimization of the invention, the jet assembly may also include an ion fan. The ion fan generates an airflow carrying positive and negative ions, which can neutralize the static electricity generated by friction during fabric processing. Static electricity is one of the important reasons why dust and fiber debris are difficult to remove; eliminating static electricity can significantly improve dust removal efficiency and prevent dust from being re-adsorbed.

[0013] As a further optimization of the invention, the housing may also be equipped with guide rollers for adjusting the fabric orientation. These guide rollers ensure that the fabric maintains flatness and correct tension as it enters and exits each processing component, preventing wrinkles or misalignment and guaranteeing the stability and continuity of the dust removal effect.

[0014] As a further optimization of the invention, the angle between the axis of the nozzle and the fabric is an acute angle. This inclined spray angle, compared to vertical spraying, generates a tangential airflow component, which is more effective in "sweeping" dust away from the fabric surface rather than blowing it into deeper pores, thereby improving the thoroughness of cleaning.

[0015] As a further optimization of the present invention, a drive shaft is fixedly connected to the output end of the drive motor, and the other end of the drive shaft is connected to the torsion member, the drive shaft passing through the cylindrical cam. This transmission structure is compact, has high transmission efficiency, simplifies the internal structure of the torsion assembly, and reduces the failure rate.

[0016] Compared with the prior art, the present invention has the following significant advantages:

[0017] 1. Deep cleaning with remarkable results: Through a unique twisting component, the fabric is twisted and rubbed, which can effectively loosen and shake out stubborn dust and fiber debris hidden deep in the porous structure, solving the problem that traditional planar vibration methods cannot achieve deep cleaning.

[0018] 2. Multiple functions work together for thorough dust removal: The three functional modules of twisting, air blowing, and suction are organically combined and act sequentially. First, the dust is "twisted" out, then "blown" away from the fabric, and finally "sucked" away and collected. The process is clear and the coordination is tight, ensuring extremely high dust removal efficiency and thoroughness.

[0019] 3. Ingenious structure and controllable cost: The complex torsional motion is achieved by adopting a purely mechanical cam-linkage structure, which avoids the use of expensive servo motors and complex control systems. This simplifies the overall structure of the equipment, significantly reduces manufacturing and maintenance costs, and makes it easy to promote in small and medium-sized enterprises.

[0020] 4. Protect the fabric and improve quality: The twisting component generates a gentle rubbing force, avoiding damage to the fibers around the holes caused by traditional violent methods such as beating with a brush stick, thus protecting the integrity and quality of the fabric.

[0033] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.

[0034] It will be understood by those skilled in the art that certain well-known structures and their descriptions may be omitted in the accompanying drawings. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0035] Example 1

[0036] A dust removal device for perforated fabric textile processing includes a stable base 1 and a closed box 2 mounted on top of the base 1. The box 2 provides a sealed space for dust removal operations, preventing dust leakage and pollution of the workshop environment. The box 2 is provided with an inlet and an outlet for the perforated fabric 100, allowing the perforated fabric 100 to enter from the bottom of the box 2, pass through the entire device from bottom to top, and exit from the top.

[0037] Inside the housing 2, along the movement path of the fabric 100, three core functional components are arranged in sequence: a twisting component 3, an air jet component 4, and a dust suction component 5. In addition, to ensure that the fabric 100 moves smoothly within the housing 2, several guide rollers 6 are installed on the housing 2 to adjust and tension the fabric 100, preventing it from deviating or wrinkling.

[0038] The torsion assembly 3 mainly consists of a housing 31, a drive motor 33, a cylindrical cam 32, a torsion member 34, two fixed blocks 36, and two friction rollers 37. The drive motor 33 serves as the power source, and its output end is connected to the torsion member 34 via a transmission shaft. The transmission shaft is cleverly designed to pass through the cylindrical cam 32, which is fixedly installed inside the housing 31. Two fixed blocks 36 are symmetrically slidably mounted on the torsion member 34 via sliders 35. Each fixed block 36 has a friction roller 37 rotatably mounted at one end via a bearing; these two friction rollers 37 together clamp the passing fabric 100. The other end of the friction rollers 37 is connected to a drive unit 38, which has a clip 39 that precisely engages in the spiral groove or specific curved groove of the cylindrical cam 32.

[0039] When the drive motor 33 starts, it drives the torsion member 34 to rotate via the transmission shaft. The rotational motion of the torsion member 34 is transmitted to the two fixed blocks 36 through the slider 35, causing them to reciprocate linearly on the guide rail of the torsion member 34. At the same time, the fixed blocks 36 drive the drive unit 38 to move, and the clips 39 on the drive unit 38, constrained by the fixed cylindrical cam 32, slide along the curved groove of the cam. As a result of this combined motion, the two friction rollers 37 not only reciprocate as a whole, but also produce a sliding motion in opposite phases along the width direction of the fabric 100. Specifically, when one friction roller 37 slides to the left, the other friction roller 37 slides to the right, and vice versa. This relative motion applies a gentle but effective torsional force to the fabric 100, similar to hand-washing clothes, thereby shaking out dust and impurities deep in the pores of the fabric 100.

[0040] Following the torsion assembly 3 is the jet assembly 4. This assembly has multiple rows of nozzles 41 symmetrically mounted on both sides of the fabric 100. To achieve optimal blowing effect, the axis of each nozzle 41 forms an acute angle (e.g., 30° to 60°) with the plane of the fabric 100. When the high-pressure airflow is ejected from these inclined nozzles 41, a strong tangential airflow is formed on the surface of the fabric 100, effectively "sweeping" away the dust that has just been loosened by the torsion assembly 3 from the surface and pores of the fabric 100, suspending it in the air within the housing 2. In this embodiment, the jet assembly 4 further integrates an ion fan 42. While generating a high-pressure airflow, the ion fan 42 ionizes the air to produce a large number of positive and negative ions. These ions can effectively neutralize the static electricity accumulated on the fabric 100 due to friction, breaking the static electricity's adsorption force on the dust, making dust removal more thorough.

[0041] At the very top of the path is the suction assembly 5, which is responsible for capturing and removing the blown-away dust. This assembly includes two suction rollers 51 with perforated surfaces, located on either side of the fabric 100. Each suction roller 51 is hollow and connected to a high-powered vacuum pump via a pipe. As the fabric 100 passes between the two suction rollers 51, the vacuum pump operates, creating negative pressure inside the suction roller 51. The powerful suction, through the numerous small holes on the roller surface, forms a uniform suction field, rapidly drawing all dust, lint, and fiber debris suspended in the air surrounding the fabric 100 into the roller, which is then discharged through the pipe system and finally captured by the collection device.

[0042] Workflow:

[0043] The perforated fabric 100 to be processed first passes through the guide roller 6 at the inlet, and is adjusted to a flat state before entering the housing 2. Then, the fabric 100 enters the torsion assembly 3, where it is repeatedly torn and rubbed by two counter-moving friction rollers 37, effectively loosening and shaking out deeply embedded dust. Next, the fabric 100 continues to move upwards, entering the working range of the jet assembly 4, where the ion air nozzles 41 on both sides spray high-speed ion airflow at acute angles, completely blowing the loosened dust away from the fabric 100. Finally, the fabric 100, carrying a small amount of suspended dust, passes through the dust collection assembly 5, where, under the powerful negative pressure suction, all remaining dust is sucked away. After this series of processes, the clean perforated fabric 100 exits from the outlet at the top of the housing 2, completing the entire dust removal process.

[0044] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
