Description

Technical Field

[0001] This utility model relates to the field of knitted fabric roll feeding technology, specifically a knitted fabric roll feeding mechanism. Background Technology

[0002] Knitted fabrics are formed by interlocking yarns on a knitting machine, offering advantages such as high elasticity, breathability, and softness against the skin. They are widely used in T-shirts, sportswear, and underwear. Their structure can be broadly classified into weft knitting (significant horizontal elasticity) and warp knitting (high longitudinal stability). During production, process parameters must be adjusted based on the fabric's weight, elasticity, and surface characteristics. Roll feeding is a crucial step in the finishing process of knitted fabrics. Through unwinding, tension control, alignment, and winding, the fabric is neatly rolled into a tube for easy storage, transportation, and subsequent cutting. Because knitted fabrics are highly elastic and easily deformed, precise tension control is necessary during rolling to avoid excessive stretching or wrinkling. Simultaneously, brush cleaning or vibration de-linting techniques are used to reduce surface impurities.

[0003] The patent document with publication number "CN 222063619 U" states that "lint floating in the air in the factory area is easily adsorbed onto the surface of the knitted fabric and thus rolled up in the interlayer." The device in the patent document rolls up the fabric and removes dust with a brush. For low-quality fabrics, the device has a good cleaning effect and low cost. However, because the brush needs to rotate at high speed, the friction between the brush and the fabric fibers can easily damage the fabric. Moreover, the brush is difficult to remove dust and other contaminants attached to the deep layers of the fabric with high quality, which is not conducive to its use. Utility Model Content

[0004] The purpose of this invention is to provide a knitted fabric roll feeding mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a knitted fabric roll feeding mechanism, comprising a support, a take-up roller, a positioning roller, a guide roller rotatably connected to the inner side of the support, a fabric fixedly connected to the upper side of the take-up roller, and a feed roller rotatably connected to the inner side of the support; a spreading dust removal mechanism and a flexible dust extraction mechanism are provided on one side of the support, and the flexible dust extraction mechanism is provided on the upper and lower sides of the spreading dust removal mechanism.

[0006] The dust-dissipating mechanism includes multiple sliding boxes, each fixedly connected to one side of a support. A sliding plate is slidably connected inside each sliding box. A bearing box is fixedly connected to one side of each sliding plate. A guide frame is fixedly connected between the bearing boxes. A dual-axis motor is fixedly connected inside each bearing box. An eccentric counterweight is fixedly connected to one output end of each dual-axis motor. Multiple hemispherical impact blocks are fixedly connected to one output end of each dual-axis motor. Multiple spreading springs are fixedly connected inside each bearing box. A slider is fixedly connected to one side of each spreading spring. An impact rod is fixedly connected to one side of each slider. A rocking spring is fixedly connected between the inner wall of the sliding box and the sliding plate.

[0007] Preferably, multiple round rods are fixedly connected to one side of the guide frame.

[0008] Preferably, the components included in the dust spreading and dust removal mechanism are all divided into two parts, and the components included in the dust spreading and dust removal mechanism are distributed on both sides of the support and are arranged in opposite directions with reference to the top and bottom.

[0009] Preferably, a columnar rod is fixedly connected inside the slide box.

[0010] Preferably, the flexible dust extraction mechanism includes multiple fan blades, a slide cylinder, and a dust exhaust port. The fan blades are fixedly connected to the output end of the dual-axis motor on the side away from the hemispherical impact block. All fan blades are disposed inside the slide box. The slide cylinder is fixedly connected to the upper and lower sides of the guide cloth frame. Each end of the slide cylinder is rotatably connected with a threaded sleeve. A sliding plate is slidably connected inside each slide cylinder. A notched threaded bracket is fixedly connected to the side of each sliding plate away from the slide cylinder. A dust extraction hood is fixedly connected to the end of each slide box. A suction pipe is provided between each dust extraction hood and the interior of the slide box. The dust exhaust port is opened on one side of the slide box.

[0011] Preferably, the notched threaded bracket has planar openings on both sides of the threaded structure, and the notched threaded bracket is slidably connected to the slide cylinder.

[0012] Preferably, each of the dust extraction hoods has a square airflow slot inside that connects to the extraction pipe and the outside of the dust extraction hood.

[0013] Compared with the prior art, the present invention provides a knitted fabric roll feeding mechanism, which has the following advantages:

[0014] The dust-dissipating mechanism is used to spread out the fabric and remove dust, lint, and other impurities from inside the fabric. This mechanism uses a movable carrier box combined with a shaking spring to increase the shaking effect. The high-speed rotation of the eccentric counterweight and the high-speed collision between the hemispherical block and the impact rod create a high-frequency vibration effect on the fabric guide frame, which shakes out the dust and protects the fabric from damage. At the same time, the mechanism reduces the subsequent vibration impact on the fabric by reasonably guiding the fabric's direction, thus improving the cleaning effect while protecting the fabric.

[0015] The flexible dust extraction mechanism is used to assist in cleaning the fabric. The mechanism covers both sides of the fabric with a dust extraction hood, so that the dust discharged when the dust extraction mechanism is spread out and works on the fabric is collected, improving the dust extraction effect. The mechanism reduces the difficulty of fabric layout by reasonably guiding the direction of the fabric and adjusting the height of the dust extraction hood, thus improving the practicality of the device.

Each sliding box 701 is fixedly connected to one side of the support 1. Each sliding box 701 has a sliding plate 702 slidably connected inside. Each sliding plate 702 has a bearing box 703 fixedly connected to one side. Each bearing box 703 has a guide frame 704 fixedly connected between them.

[0028] Furthermore, the components included in the dust removal mechanism 7 are all divided into two parts. The components included in the dust removal mechanism 7 are distributed on both sides of the support 1 and are arranged in opposite directions with reference to the up and down.

[0029] Furthermore, a columnar rod is fixedly connected inside the slide box 701. Example

[0030] This device is used for dust control, and it improves dust removal efficiency and adjustability. Please refer to [link / reference needed]. Figure 1-5Furthermore, in conjunction with Embodiment 1, the flexible dust extraction mechanism 8 includes multiple fan blades 801, a slide cylinder 802, and a dust discharge port 808. The fan blades 801 are fixedly connected to the output end of the dual-axis motor 705 on the side away from the hemispherical impact block 707. All fan blades 801 are arranged inside the slide box 701. The slide cylinder 802 is fixedly connected to the upper and lower sides of the guide cloth frame 704. The ends of the slide cylinder 802 are rotatably connected to the threaded sleeves 803. The slide cylinder 802 is slidably connected to the slide plate 804. The side of the slide plate 804 away from the slide plate is fixedly connected to the notched threaded frame 805. The ends of the slide plate 804 are fixedly connected to the dust extraction hood 806. The dust extraction hood 806 and the interior of the slide box 701 are connected by a suction pipe 807. The dust discharge port 808 is opened on one side of the slide box 701.

[0031] Furthermore, the notched threaded bracket 805 has planar openings on both sides of the threaded structure, and the notched threaded bracket 805 is slidably connected to the slide cylinder 802.

[0033] In actual operation, when this device is used, the user loads the fabric 5 onto the feed roller 6, and then passes the fabric 5 sequentially through multiple round rods of the guide frame 704, the guide roller 4, the positioning roller 3, and the take-up roller 2. The user then starts the dual-axis motor 705 and begins feeding. As the dual-axis motor 705 drives the eccentric counterweight 706 to rotate at high speed, centrifugal vibration is generated. This vibration, caused by the dual-axis motor 705, drives the hemispherical impact block 707 to continuously collide with the impact rod 710, increasing the vibration frequency. The fabric 5 moves on the guide frame 704... In a loose state, the guide frame 704, vibrated by the slide box 701, shakes off the dust from the surface of the fabric 5. Then, the fabric 5 is driven by the take-up roller 2 to rotate and begin to be wound up. At the same time, the dual-axis motor 705 drives the fan blades 801 to generate negative pressure inside the dust extraction hood 806. The user can rotate the screw sleeve 803 as needed to adjust the distance between the dust extraction hood 806 and the fabric 5, making it easy to adjust the air pressure intensity. The dust is discharged from the discharge port under the action of the fan blades 801, making the fabric 5 clean and tidy, while protecting the fabric 5.
