Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, and in particular to a knitted fabric opening machine that reduces lint adhesion. Background Technology

[0002] Knitted greige fabric refers to the raw fabric that has been formed by knitting machines by bending yarns into loops and interlocking them to form a fabric, without dyeing, printing, setting or other finishing processes. Its surface retains the lubricant or sizing agent from the weaving process, and it has characteristics such as clear loop structure, high elasticity and easy edge curling. It is the basic material for subsequent dyeing and finishing processes.

[0003] In existing technologies, loose lint easily adheres to the outer surface of knitted fabrics. If it is not cleaned in time, the lint will become embedded in the gaps between the loose yarns of the fabric during subsequent operations. This can cause color spots on the fabric surface during dyeing and can easily form molten hard particles or scorch spots during high-temperature setting, resulting in product downgrading or even scrapping. Utility Model Content

[0004] This utility model discloses a knitted fabric opening machine that reduces lint adhesion, aiming to solve the technical problem that free lint easily adheres to the outer surface of knitted fabric, and if it is not cleaned in time, it will lead to product downgrading or even scrap.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a knitted fabric opening machine for reducing lint adhesion, comprising: a main frame, on which a mounting frame is fixedly connected; a driven roller, both ends of which are rotatably connected to the mounting frame; a driving roller, both ends of which are rotatably connected to the mounting frame; a drive motor, fixedly connected to one side of the mounting frame, the output end of which is fixedly connected to one end of the driving roller; and a cleaning module, located on one side of the main frame and on the mounting frame, the cleaning module comprising two hollow rollers, both ends of which are rotatably connected to the mounting frame, each hollow roller having multiple mounting slots and suction ports equidistantly spaced around its circumference, each mounting slot containing a fixed brush component; the cleaning module further comprising a fixed frame, fixedly connected to the upper surface of the mounting frame, the fixed frame having two fixing holes, each fixing hole containing an eccentric rod, the two eccentric rods being located in corresponding hollow sections. The roller has mounting kits inside and outside the two eccentric rods. Scraper pieces are fixedly connected to one side of each mounting kit, and mounting parts are fixedly connected to both ends of each mounting kit. Multiple mounting parts are located outside the corresponding eccentric rods, and contact blocks are fixedly connected to one side of each mounting part. Multiple contact blocks are in close contact with the inner wall of the corresponding hollow roller. A collection box is provided on one side of the main frame. A negative pressure pump is provided on the upper surface of the collection box. The suction end of the negative pressure pump is connected to the collection box. A connecting pipe is provided on the top of the collection box. One end of the connecting pipe is connected to the collection box. A connecting chamber is provided at the end of the connecting pipe away from the collection box. The two inlet ends of the connecting chamber are connected to the corresponding hollow rollers. Transmission gears are fixedly connected to the outside of one end of each of the two hollow rollers. The teeth of the two transmission gears can mesh with each other. A universal motor is fixedly connected to the fixed frame. Transmission wheels are fixedly connected to the output end of the universal motor and the outside of one end of the corresponding hollow roller. The two transmission wheels are connected to the same transmission belt.

[0006] Equipped with a cleaning module, the universal motor rotates the transmission wheel, which in turn drives the lower hollow roller to rotate via a transmission belt. The meshing of two transmission gears further rotates the upper hollow roller. The two hollow rollers rotate in opposite directions, opposite to the direction of the knitted fabric's movement. A brush removes lint adhering to the outer surface of the fabric. Simultaneously, a negative pressure pump activates, creating a negative pressure inside the collection box. Connected to the two hollow rollers via a connecting pipe and a connecting chamber, negative pressure is generated at the suction inlets on the two hollow rollers, drawing the brushed-off lint into the rollers. The lint is then collected and stored in the collection box via the connecting chamber and connecting pipe. As the hollow rollers rotate, the scraper and the hollow... The rollers move in opposite directions, scraping off any lint that may remain on the inner wall of the hollow roller. Simultaneously, the contact block contacts the inner wall of the hollow roller, twisting as the hollow roller rotates until it separates from the inner wall. The twisted contact block then quickly recovers its original shape, repeating this process continuously. This vibration is transmitted to the scraper, shaking off any lint adhering to it and preventing lint from accumulating. The device utilizes the opposing counter-rotating rotation of the double hollow rollers to drive the brush to remove lint from the fabric surface. At the same time, a negative pressure system instantly removes the brushed lint, preventing secondary adhesion. Furthermore, the synergistic effect of the scraper and the contact block prevents lint from accumulating inside the device, ensuring continuous operation.

[0007] In a preferred embodiment, the mounting frame is provided with an auxiliary module, which includes a rotating rod. Both ends of the rotating rod are rotatably connected to the mounting frame. A fixing kit is fixedly connected to the outside of the rotating rod. Multiple connecting rods are fixedly connected at equal intervals around the outer circumference of the fixing kit. A sliding rod is fixedly connected to the end of each of the multiple connecting rods away from the fixing kit. Both ends of the multiple sliding rods are fixedly connected to mounting rods, and movable kits are movably connected to the outside of each of the two mounting rods. The main frame has mounting holes and rotating holes. A guide roller is provided in the mounting hole, and a winding roller is rotatably connected in the rotating hole. A winding motor is fixedly connected to one side of the main frame, and the output end of the winding motor is fixedly connected to one end of the winding roller.

[0008] With the auxiliary module, when the knitted fabric slides above the sliding rod, the rotating rod rotates, and the fabric slides and spreads out to both sides by gravity. At the same time, the movable kit rotates as the fabric slides, reducing the friction between the knitted fabric and the device when it slides and spreads out, thus reducing the generation of lint.

[0009] As can be seen from the above, the knitted fabric opening machine that reduces lint adhesion provided by this utility model uses a cleaning module to drive the brush to remove lint from the surface of the fabric by the opposite rotation of double hollow rollers. At the same time, the brushed lint is immediately extracted by a negative pressure system to prevent secondary adhesion. Furthermore, the synergistic effect of the scraper and the contact block prevents lint from accumulating inside the device, ensuring the continuous operation of the device.

[0015] Reference Figure 1 , Figure 2 and Figure 5In a preferred embodiment, an auxiliary module 7 is provided on the mounting frame 2. The auxiliary module 7 includes a rotating rod 701, both ends of which are rotatably connected to the mounting frame 2. A fixing kit 702 is fixedly connected to the outside of the rotating rod 701. Multiple connecting rods 703 are fixedly connected at equal intervals around the outer circumference of the fixing kit 702. A sliding rod 704 is fixedly connected to the end of each of the multiple connecting rods 703 away from the fixing kit 702. Mounting rods 705 are fixedly connected to both ends of the multiple sliding rods 704. Movable kits 706 are movably connected to the outside of each of the two mounting rods 705.

A winding motor 10 is fixedly connected to one side of the main frame 1. The output end of the winding motor 10 is fixedly connected to one end of the winding roller 9.

[0016] Working principle: After being split by a slitting knife, the knitted fabric passes over the auxiliary module 7, between the driving roller 4 and the driven roller 3, and then slides through two hollow rollers 606 to the outside of the guide roller 8. It then winds around the outside of the take-up roller 9. The take-up motor 10 and drive motor 5 are started. The take-up motor 10 drives the take-up roller 9 to rotate and take up the knitted fabric. The drive motor 5 drives the driving roller 4 to rotate and convey the knitted fabric, and the driven roller 3 rotates accordingly. When the knitted fabric slides above the sliding rod 704, the rotating rod 701 rotates, and the fabric slides and spreads out to both sides due to gravity. At the same time, the movable kit 706 rotates with the fabric, reducing the friction between the knitted fabric and the device when it slides and spreads out, thus reducing lint generation. The general-purpose motor 609 is started to rotate the transmission wheel 610, which drives the lower hollow roller 606 to rotate via the transmission belt 611. Through the meshing of two transmission gears 607, the upper hollow roller 606 rotates. The two hollow rollers 606 rotate in opposite directions, and their rotation direction is the same as that of the knitted fabric. The fabric moves in the opposite direction, and the brush 616 brushes off the lint adhering to the outer surface of the fabric. Simultaneously, the negative pressure pump 602 starts, creating a negative pressure inside the collection box 601. This collection box is connected to two hollow rollers 606 via a connecting pipe 603 and a connecting chamber 604. Negative pressure is generated at the suction inlets of the two hollow rollers 606, drawing the brushed-off lint into them. The lint is then collected and stored in the collection box 601 via the connecting chamber 604 and the connecting pipe 603. When the hollow rollers 606 rotate, the scraper 6... 13 moves relative to the hollow roller 606, scraping off any lint that may remain on the inner wall of the hollow roller 606. At the same time, the contact block 615 contacts the inner wall of the hollow roller 606. The contact block 615 twists as the hollow roller 606 rotates until it separates from the inner wall of the hollow roller 606. Then the contact block 615 quickly recovers its twisted state. This process is repeated, continuously generating vibrations that are transmitted to the scraper 613, shaking off any lint adhering to the scraper 613 and preventing lint from adhering and accumulating on the scraper 613.
