Description

Technical Field

[0001] This invention relates to the field of textile production technology, and in particular to a weft knitting double-sided machine for producing three-dimensional fleece fabric. Background Technology

[0002] 3D fleece fabrics are typically manufactured using circular knitting machines. After weft knitting, the fabric is wound up and stored by take-up rollers located below the machine. Existing take-up structures usually operate synchronously with the circular knitting machine's discharge mechanism, ensuring the fabric is wound up without twisting.

The extension and retraction of the tension push rod controls the extension and retraction of the two rotating supports. The two rotating supports expand the fabric from the inside to the outside, smoothing out the fabric wrinkles and preventing wrinkles when the fabric is rolled up.

When the pile brush rollers rotate and clean the fabric, the lint on the surface of the pile brush rollers is separated by the scraper claws at the edge of the impurity scraper plate. Under the action of the impurity removal fan, a negative pressure is generated inside the negative pressure impurity remover. The airflow quickly flows into the negative pressure impurity remover through the inlet, passes through the filter and flows to the impurity removal fan. During this process, the airflow sucks in the lint on the surface of the impurity scraper plate and follows it into the filter. The air passes through the filter plate and enters the impurity removal fan, while the lint and other impurities are intercepted by the filter plate.

By tensioning the telescopic top rod 402 with the tension spring 404, the two rotating supports 403 are kept under tension, maintaining the expansion tension on the fabric and preventing excessive displacement of the tension push rod 4 from damaging the fabric.

[0024] Two pile brush rollers 6 are rotatably connected between the two connecting plates 5. The lower end of the rotating support 403 is located between the two pile brush rollers 6. The ends of the pile brush rollers 6 are fixedly connected to the linkage gears 602. The two linkage gears 602 mesh to form a gear transmission. The right connecting plate 5 is fixedly connected to the brush roller drive motor 601. The shaft of the brush roller drive motor 601 is connected to and drives one of the pile brush rollers 6. Under the drive of the brush roller drive motor 601, the two pile brush rollers 6 rotate synchronously and in opposite directions to clean the two surfaces of the fabric respectively.

[0025] Two impurity scraping plates 7 are fixedly connected between the two connecting plates 5, and the edges of the impurity scraping plates 7 are in contact with the roller surface of the napped brush roller 6. The two napped brush rollers 6 at the front and rear of the fabric rotate and brush the fabric, removing a small amount of nap from the fabric surface, improving the surface cleanliness of the fabric, and at the same time, they have the cleaning function of the napped brush roller 6. When the napped brush roller 6 rotates to clean the fabric, the scraping claws on the edge of the impurity scraping plate 7 separate the nap from the surface of the napped brush roller 6.

[0026] A tension adjusting motor 302 is fixedly connected inside the rotating connecting rod 3. The tension adjusting motor 302 is connected to and drives the tension adjusting screw 303.

A strip-shaped groove is opened on the inner surface of the side connecting cylinder 301. A tensioning push rod 4 is slidably connected inside the side connecting cylinder 301. A strip-shaped protrusion is opened on the outer surface of the tensioning push rod 4. The protrusion is slidably connected to the groove to guide the tensioning push rod 4 and prevent it from rotating with the tension adjusting screw 303. The two ends of the tension adjusting screw 303 rotate in opposite directions so that when the tension adjusting screw 303 rotates in the same direction, it can drive the two tensioning push rods 4 to move away or closer at the same time.

The upper end of the telescopic top rod 402 has an inwardly bent arc structure. The tension adjusting motor 302 drives the tension adjusting screw 303 to rotate. Through the spiral transmission between the tension adjusting screw 303 and the spiral push hole 401, the tensioning push rod 4 is pushed to slide inside the side connecting cylinder 301, controlling the distance between the two rotating supports 403 and adjusting the expansion range of the fabric cylinder.

The scraper claws at the edge of the plate 7 separate the lint from the surface of the velvet brush roller 6. Under the action of the impurity removal fan 806, a negative pressure is generated inside the negative pressure impurity remover 8. The airflow quickly flows into the negative pressure impurity remover 8 through the suction port 801, and flows through the filter 803 to the impurity removal fan 806. During this process, the airflow scrapes the lint off the surface of the plate 7 and sucks it in, and follows it into the filter 803. The air passes through the filter plate 805 and enters the impurity removal fan 806. Lint and other impurities are intercepted by the filter plate 805.

[0029] In Embodiment Two, based on Embodiment One, a winding motor 1001 is fixedly connected to the right end face of the winding bracket 10. A roller rotating connector 1002 is fixedly connected to the end of the rotating shaft of the winding motor 1001. The roller rotating connector 1002 is located inside the right end of the winding bracket 10. A cylindrical boss is provided on the side of the winding motor 1001 facing the center of the winding bracket 10. A roller clamping push cylinder 1003 is fixedly connected to the left end face of the winding bracket 10. A roller positioning connector 1004 is rotatably connected to the end of the push rod of the roller clamping push cylinder 1003 through a bearing. A cylindrical boss is fixedly connected to the side of the roller positioning connector 1004 facing the center of the winding bracket 10. The roller rotating connector 1002 and the roller positioning connector 1004 are connected to each other. Coaxial; the take-up bracket 10 rotates synchronously with the output fabric tube of the three-dimensional pile weft knitting machine 1 under the drive of the rotary synchronous motor 9. Under normal conditions, the roller clamping push cylinder 1003 applies a pushing force to the roller positioning seat 1004, so that the take-up roller is fixed under the joint cooperation of the roller rotating seat 1002 and the roller positioning seat 1004, and rotates under the drive of the take-up motor 1001 to realize the take-up of the fabric. When changing the fabric roll, the roller clamping push cylinder 1003 is controlled to retract, so that the distance between the roller rotating seat 1002 and the roller positioning seat 1004 increases, so that the fabric roll is pulled out from the cylindrical boss of the roller rotating seat 1002 and the roller positioning seat 1004, realizing the quick disassembly and installation of the fabric roll.

[0030] The working principle of this embodiment is as follows: First, the 3D fleece fabric is weft-knitted by the 3D fleece weft knitting machine 1. The finished fabric is cylindrical and output downwards from the finished product outlet 2. After being expanded by the rotating support 403, it enters between the two fleece brush rollers 6 and is wound up into the fabric roll above the take-up bracket 10. Driven by the rotary synchronous motor 9, the take-up bracket 10 rotates synchronously with the output fabric roll of the 3D fleece weft knitting machine 1. The roller clamping push cylinder 1003 applies a pushing force to the roller positioning seat 1004, causing the take-up roller to... The roller rotating bracket 1002 and the roller positioning bracket 1004 are fixed together and rotated under the drive of the winding motor 1001 to achieve the winding of the fabric. The fabric is expanded from the inside to the outside by the two rotating supports 403, smoothing out the fabric wrinkles and avoiding wrinkles during the winding process. At the same time, the tension spring 404 tightens the telescopic top rod 402, maintaining tension on the two rotating supports 403 and maintaining the expansion tension on the fabric, preventing excessive displacement of the tension push rod 4 that could damage the fabric. Two velvet brush rollers 6, one at the front and one at the back of the fabric, rotate and brush the fabric, removing a small amount of lint from the fabric surface and improving the surface cleanliness. These brush rollers 6 also have a cleaning function. While cleaning the fabric, the lint on the surface of the brush rollers 6 is separated by the scraping claws at the edge of the impurity scraping plate 7. Under the action of the impurity removal fan 806, a negative pressure is generated inside the negative pressure impurity remover 8, and the airflow quickly flows into the negative pressure impurity remover 8 through the suction port 801 and passes through the filter. The airflow from 803 to the impurity removal fan 806 draws in the lint on the surface of the filter 7 through the airflow, and the lint is drawn into the filter 803. The air passes through the filter plate 805 and enters the impurity removal fan 806. Lint and other impurities are intercepted by the filter plate 805. While cleaning the surface of the three-dimensional velvet fabric, it also has the function of cleaning the velvet brush roller 6, maintaining the cleaning efficiency of the velvet brush roller 6 on the three-dimensional velvet fabric. The filter plate 805 is periodically removed for cleaning to maintain the high efficiency of the negative pressure impurity remover 8.
