Description

Technical Field

[0001] The utility model relates to the field of trimming parts, and more particularly to a device for trimming the pile of pile fabrics. Background Art

[0002] Fluff fabric is a textile with a rich surface of fluff or short fibers. The surface has long or short fluff, which gives the fabric a soft feel, good warmth retention, and a unique visual effect. During the production of fluff fabric, a shearing device is required to smooth the fluff. However, in the prior art, traditional shearing equipment often simply maintains the cutter at a certain height and sweeps the cutter across the fabric, completing the shearing process through contact between the cutter and the fluff on the fabric surface. In actual production, this method has certain problems, mainly because the fluff is light in weight and has different shapes. It is often pushed down by the cutter blade instead of being cut, which easily leads to uneven fluff.

[0003] Based on the above, the purpose of the present invention is to provide a device for trimming the pile of pile fabrics to solve the above problems. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the purpose of the utility model is to provide a device for trimming the fluff of fluff fabrics. The utility model arranges a roller to rotate in a box, and then arranges a hook on the roller. The roller and the hook are used to pull out and tighten the fluff on the fluff fabric, and then the fluff is trimmed by the fluff cutting mechanism, so that the trimming of the fluff is more stable and neat.

[0005] The above-mentioned technical purpose of the present utility model is achieved through the following technical solutions: a fluff trimming device for fluff fabrics, comprising a box body, a feed port and a discharge port are provided on the box body, a roller is rotatably connected to the box body, a plurality of hooks are provided on the roller, a mounting plate and a cleaning module are provided next to the roller, the cleaning module can remove the fluff on the hooks, a fluff cutting module is provided on the mounting plate, a displacement mechanism for driving the mounting plate to move is provided on the box body, the distance between the fluff cutting module and the fluff fabric can be controlled by the displacement mechanism, and a plurality of guide rollers for guiding the fluff fabric are provided in the box body.

[0006] By adopting the above technical solution, when the fluff fabric needs to be trimmed, the fluff fabric is pulled into the box through the feed port, then passed through multiple guide rollers and discharged from the discharge port, and then connected to the external winding device.

[0025] A device for trimming the pile of pile fabrics, such as Figure 1-Figure 5 As shown, it includes a box body 1, which is provided with a feed port 2 and a discharge port 3. A roller 4 is rotatably connected inside the box body 1, and a plurality of hooks 5 are fixedly connected to the roller 4. A mounting plate 6 and a cleaning module are provided next to the roller 4. The cleaning module can remove the fluff on the hook 5. A fluff cutting module is provided on the mounting plate 6. A displacement mechanism for driving the mounting plate 6 to move is provided on the box body 1. The distance between the fluff cutting module and the fluff fabric can be controlled by the displacement mechanism. A plurality of guide rollers 7 for guiding the fluff fabric are rotatably connected inside the box body 1.

[0026] Furthermore, the fluff cutting module includes a cutting knife 8 fixedly connected to the mounting plate 6, and a cutting knife 2 9 is slidably connected to the mounting plate 6. Both the cutting knife 1 8 and the cutting knife 2 9 are processed with a serrated blade. A motor (not shown in the figure) is installed on the mounting plate 6, and a cam 10 is fixedly connected to the output shaft of the motor. The cam 10 is provided with a drive shaft 11 with one end rotatably connected to it, and the other end of the drive shaft 11 is rotatably connected to the cutting knife 2 9.

[0027] Furthermore, a support roller 12 is rotatably connected to one side of the box body 1 close to the mounting plate 6 , and both the cutting blade 1 8 and the cutting blade 2 9 are arranged in a lightning shape, thereby avoiding the support roller 12 .

[0028] Furthermore, the displacement mechanism includes a lifting frame 13 slidably connected to the box body 1, and both sides of the mounting plate 6 are fixedly connected to both sides of the lifting frame 13. An electric push rod 14 is installed on the box body 1, and the protruding end of the electric push rod 14 is fixedly connected to the lifting frame 13.

[0029] Furthermore, the cleaning module includes a brush roller 15 rotatably connected to the box body 1 , the brush roller 15 and the drum 4 rotate relative to each other, the rotation speed of the brush roller 15 is faster than that of the drum 4 , and a collection tank 16 with a drawer structure is slidably connected to the box body 1 .

[0030] Furthermore, a collision rod 17 is fixedly connected to one side of the box body 1 close to the brush roller 15 .

[0031] Furthermore, a plurality of through slots 18 are formed on the drum 4 , and a negative pressure air hood 19 is installed in the box body 1 , and the negative pressure air hood 19 extends into the drum 4 .

[0032] It should be mentioned that the drum 4 and the brush roller 15 can be driven to rotate by an external motor or other driving mechanism. This is a mature existing technology and will not be elaborated here.

[0033] Working principle: When the fluff of the fluff fabric needs to be trimmed, the fluff fabric is pulled into the box 1 through the feed port 2 with the fluff side facing down, and then discharged from the discharge port 3 after passing through multiple guide rollers 7. It is then connected to the external winding device, and the fluff fabric is pulled to move under the drive of the winding device. In this process, the driving roller 4 is rotated so that the rotation direction of the roller 4 is the same as the movement direction of the fluff fabric. During the rotation of the roller 4, the hook 5 will hook the fluff on the fabric and straighten it. The external negative pressure equipment and the negative pressure wind hood 19 can also apply a suction force to the fluff to make the fluff in a straightened state.

[0034] Then the fluff cutting module cuts off the excess fluff: the motor drives the cam 10 to rotate, and the cam 10 drives the cutting knife 2 9 to move back and forth through the drive shaft 11, and then the fluff stuck in the serrated structure of the cutting knife 1 8 is cut off through the serrated blade structure, so that the fluff on the fabric is at an appropriate length. The support roller 12 will play a certain supporting role on the fabric to prevent the fabric from being pulled by the hook 5 and deviating too much downward, causing a large deviation in the cutting length. The user can also reduce the error by setting the cutting reserve.

[0035] The rapidly rotating brush roller 15 will brush off the fluff that remains on the hook 5. When the rotating fluff roller rotates, the brush will hit the collision rod 17, and the impact force and vibration generated by the hitting will throw the fluff out. The fluff will then fall into the collection tank 16 and wait for cleaning. The negative pressure hood will also suck away some of the cut fluff. A filtering structure can be set between the suction hood and the external negative pressure equipment to block and collect these fluffs. The user can also adjust the distance between the cutting knife and the fabric in the fluff cutting module through the electric push rod 14 and the lifting frame 13, thereby controlling the cutting length of the fluff.

[0036] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
