Description

Technical Field

[0001] This utility model relates to a lint suction device, specifically a lint suction device for a printing machine. Background Technology

[0002] A printing machine is a machine used to print on fabrics. It has the functions of printing, drying, setting, and collecting fabric fibers. During the printing process, some lint may be present on the fabric surface. The printing machine applies dye to the fabric and forms a pattern. However, the presence of a certain amount of lint on the fabric can cause color confusion after the lint is dyed and falls off or moves, thus affecting the printing effect. On the one hand, the lint attached to the fabric can affect subsequent processing; on the other hand, the lint may float in the air, polluting the workshop environment. To reduce lint on the fabric and clean the workshop environment, this application provides a lint suction device for a printing machine. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the prior art, this utility model provides a lint suction device for a printing machine, which effectively solves the problem of residual lint on the fabric.

[0004] To achieve the above objectives, the present invention provides the following technical solution: The present invention includes a lint suction box;

[0005] The top opening of the lint suction box is connected to the guide cloth roller through a bearing assembly at its bottom inner side. The outer circumferential surface of the guide cloth roller is fixedly provided with spirally distributed brushes.

[0006] The top of the hair-collecting box is connected to one end of the first corrugated pipe via a flange, and the other end of the first corrugated pipe is connected to the air inlet of the fan; the air outlet of the fan is connected to the top of the second corrugated pipe via a quick-release connector.

[0007] The bottom end of the second corrugated pipe is detachably connected to the wire mesh cylinder via a clamp; the bottom of the wire mesh cylinder extends into the inner cavity of the water storage tank, and the water storage tank is filled with water that submerges the bottom of the wire mesh cylinder.

[0008] Preferably, the guide roller is horizontally positioned at the bottom of the lint suction box, with its axis perpendicular to the fabric travel direction.

[0009] Preferably, the bristles of the brush are made of nylon and are arranged in an alternating spiral pattern along the surface of the guide roller.

[0010] Preferably, the wire mesh tube uses an 80-120 mesh size.

[0011] Preferably, the drive shaft of the guide roller is rigidly connected to the output shaft of the drive motor via a coupling.

[0012] Preferably, the opening of the lint suction box is divided into a feeding side and a discharging side along the axial direction of the guide roller, and the fabric extends out from the discharging side through the feeding side, passing around the guide roller, to form a V-shape.

[0013] Beneficial effects: 1. High-efficiency lint removal: The drive motor rotates the guide roller, and the nylon brushes with their staggered spiral arrangement on the surface make full contact with the fabric, brushing thoroughly and meticulously to efficiently remove lint from the fabric surface. The fan creates negative pressure in the lint suction box, quickly sucking away the brushed lint, greatly improving cleaning efficiency and ensuring printing quality;

[0014] 2. Environmentally friendly and pollution-free: The fluff enters the wire mesh cylinder through the fan and corrugated pipe, where it is intercepted by the 80-120 mesh screen. Some of the fluff is wetted by the water at the bottom of the cylinder, preventing the fluff from flying again. This effectively avoids fluff pollution in the workshop, improves the working environment, and protects the health of operators. Attached Figure Description

[0021] The following is in conjunction with the appendix Figure 1-4 The specific embodiments of this utility model will be described in further detail.

[0022] Example 1, by Figure 1-4 The present invention provides a lint suction device for a printing machine, comprising a lint suction box 1, a guide roller 2, a brush 3, a feeding side 4, a discharging side 5, a first corrugated pipe 6, a fan 7, a second corrugated pipe 8, a screen cylinder 9, a water storage tank 10, and a drive motor 11.

[0023] The top opening of the lint suction box 1 is connected to the guide roller 2 via a bearing assembly at its inner bottom. The outer circumferential surface of the guide roller 2 is fixedly provided with spirally distributed brushes 3.

[0024] The top of the hair-collecting box 1 is connected to one end of the first corrugated pipe 6 via a flange, and the other end of the first corrugated pipe 6 is connected to the air inlet of the fan 7; the air outlet of the fan 7 is connected to the top of the second corrugated pipe 8 via a quick-release connector.

[0025] The bottom end of the second corrugated pipe 8 is detachably connected to the wire mesh cylinder 9 by a clamp; the bottom of the wire mesh cylinder 9 extends into the inner cavity of the water storage tank 10, and the water storage tank 10 is filled with water that submerges the bottom of the wire mesh cylinder 9.

[0026] Structure of the lint suction box 1 and the guide roller 2: The top of the lint suction box 1 is open, and the bottom of its inner side is rotatably connected to the guide roller 2 via a bearing assembly. The guide roller 2 is horizontally positioned at the bottom of the lint suction box 1, with its axis perpendicular to the direction of fabric travel. Spiral-distributed brushes 3 are fixedly mounted on the outer circumferential surface of the guide roller 2. The bristles of the brushes 3 are made of nylon and arranged in an alternating spiral pattern along the surface of the guide roller 2.

[0027] Suction assembly connection: The top of the suction box 1 is connected to one end of the first corrugated pipe 6 via a flange, and the other end of the first corrugated pipe 6 is connected to the air inlet of the fan 7. The air outlet of the fan 7 is connected to the top of the second corrugated pipe 8 via a quick-release connector.

[0028] Floss collection structure: The bottom end of the second corrugated pipe 8 is detachably connected to the wire mesh tube 9 via a clamp. The wire mesh tube 9 uses an 80-120 mesh mesh, and its bottom extends into the inner cavity of the water storage tank 10, which is filled with water that submerges the bottom of the wire mesh tube 9.

[0029] Power drive: The drive shaft of the guide roller 2 is rigidly connected to the output shaft of the drive motor 11 through a coupling.

[0030] Fabric guiding: The opening of the lint suction box 1 is divided into the feeding side 4 and the discharge side 5 along the axial direction of the guide roller 2. The fabric passes through the feeding side 4, around the guide roller 2, and extends out from the discharge side 5 to form a V-shape.

[0031] Working Principle: During the operation of the printing machine, the lint suction device of this invention works systematically. First, the printing machine begins to convey the fabric, at which point the operator starts the drive motor 11. The drive motor 11 serves as the power source, and its output shaft is rigidly connected to the transmission shaft of the guide roller 2 via a coupling. This rigid connection ensures efficient power transmission. As the drive motor 11 operates, the guide roller 2 begins to move in a circular motion at a set speed.

[0032] The brushes 3, fixedly mounted on the outer circumferential surface of the guide roller 2, play a crucial role during the rotation of the guide roller 2 due to their special structure of interlaced spiral lines. As the fabric enters from the feed side 4 of the lint-collecting box 1, travels along the surface of the guide roller 2, and extends out from the discharge side 5, forming a V-shaped trajectory, the brushes 3 make full contact with the fabric surface. Because the bristles of the brushes 3 are made of nylon, which is flexible and elastic, they can perform a comprehensive and meticulous brushing of the fabric surface under the drive of the guide roller 2. During this brushing process, the lint originally attached to the fabric surface is brushed up one by one and detached from the fabric.

[0033] Simultaneously, the operator starts the blower 7. Once the blower 7 is running, its powerful suction capacity creates a negative pressure environment within the lint suction box 1 through the first corrugated pipe 6. The top of the lint suction box 1 is connected to the first corrugated pipe 6 via a flange. This connection method ensures both stability and good sealing, allowing the negative pressure within the lint suction box 1 to effectively act on the internal space. The lint brushed up by the brush 3, under the influence of the negative pressure within the lint suction box 1, quickly moves towards the blower 7, passes through the first corrugated pipe 6, and enters the blower 7.

[0034] The air outlet of the blower 7 is connected to the top of the second corrugated pipe 8 via a quick-release connector. The quick-release connector design facilitates rapid disassembly and installation during equipment maintenance or component replacement. The mixture of fluff and airflow accelerated by the blower 7 continues to flow downwards along the second corrugated pipe 8. The bottom end of the second corrugated pipe 8 is detachably connected to the wire mesh cylinder 9 via a clamp, and the mixture of fluff and airflow ultimately reaches the wire mesh cylinder 9.

[0035] The screen tube 9 uses an 80-120 mesh size, which effectively traps lint. Simultaneously, the bottom of the screen tube 9 extends into the inner cavity of the water tank 10, which is filled with water to submerge the bottom of the screen tube 9. When the lint and airflow mixture passes through the screen tube 9, the lint is trapped by the mesh, while the airflow passes through and is discharged. Some of the trapped lint becomes wet upon contact with the water, further increasing its weight and making it difficult for it to fly away again. This achieves efficient lint collection and processing, ensuring a clean working environment for the printing machine and that printing quality is not affected by lint.

[0036] Beneficial effects: This utility model has a novel structure and ingenious design. By adding a fan 7, a water bucket 10, and a wire mesh cylinder 9 to remove impurities such as lint from the fabric, the device has a good lint removal effect and a good dust prevention effect, which improves product quality and significantly reduces the number of printing defects after printing. The number of downgrades caused by lint decreased from 0.113% in January 2024 to 0.071% in October 2024.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
