Description

Technical Field

[0001] The utility model relates to the technical field of napping fabrics, in particular to a napping device for fabrics. Background Art

[0002] In the process of napping fabrics, the use of napping agents is a key step, which can significantly affect the napping effect and the final quality of the fabrics. Double-sided napping adopts an upper and lower double napping roller setting, and transmission guide rollers are usually distributed on the front and back sides of the napping rollers. When feeding the fabric, the fabric needs to pass between the transmission guide rollers and between the upper and lower sets of napping rollers at the same time. Since there is a long distance between the transmission guide roller and the napping roller, the operation is time-consuming and cumbersome when re-feeding the fabric.

[0003] Therefore, this solution proposes a napping device for fabrics, which can improve the convenience of fabric feeding through structural settings. Utility Model Content

[0004] The utility model aims at least to solve the problem of inconvenience in feeding fabrics in the prior art.

[0005] The present invention provides a fabric napping device, which is achieved by the following specific technical means: it comprises two groups of upper and lower napping rollers that cooperate with each other, vertical frames are distributed at both ends of the napping rollers, and slide grooves are opened on the upper and lower sides of the vertical frames, and mounting seats are slidably arranged in the slide grooves, and the roller shafts of the upper and lower groups of the napping rollers are rotatably connected with the upper and lower groups of mounting seats respectively. At the same time, convex plates are fixed on both sides of the middle part of the vertical frames, and inclined grooves are symmetrically opened at the upper and lower ends of the convex plates, and slide seats are slidably arranged in the inclined grooves, and a group of guide rollers are rotatably installed on each group of the slide seats, and the slide seat located on the upper side of the convex plate is hingedly connected to a group of mounting seats located on the upper side of the vertical frame through a connecting rod 1, and the slide seat located on the lower side of the convex plate is hingedly connected to a group of mounting seats located on the lower side of the vertical frame through a connecting rod 2. When the two groups of mounting seats move away from each other, the two groups of guide rollers on each group of convex plates will be driven away from each other, and at the same time, the guide rollers on the two groups of convex plates will be brought closer to each other.

[0006] Preferred technical solution 1: The two groups of inclined grooves on the convex plate are close to each other at one end away from the stand, so that when the two groups of mounting seats are close to each other, the two groups of guide rollers on one convex plate are also pushed close to each other.

[0007] Preferred technical solution 2: A double-headed screw is rotatably mounted on the stand, and the two groups of mounting seats are sleeved on both ends of the double-headed screw through threaded holes.

[0008] Preferred technical solution three: A power mechanism is installed on the stand, and the power mechanism is connected to the roller shafts of the upper and lower groups of napping rollers at the same time, so as to drive the two groups of napping rollers to rotate synchronously in opposite directions.

[0009] Preferred technical solution four: the power mechanism includes a vertical shaft rotatably arranged on a vertical frame, a sleeve shaft rotatably penetrates the mounting seat, and the sleeve shaft is slidably sleeved on the vertical shaft, and is meshed with a bevel gear 1 fixedly sleeved on the sleeve shaft and a bevel gear 2 fixedly sleeved on the end of the roughening roller shaft.

[0010] Preferred technical solution five: A second motor connected to the vertical axis is fixed inside the stand.

[0011] The above structure enables this solution to have the following beneficial effects:

[0012] 1. The linkage control between the napping roller and the guide roller is realized through the linkage structure. Before feeding the fabric, the two sets of napping rollers are moved away from each other, and the guide rollers on the left and right sides are linked to move closer to each other and move between the two sets of napping rollers. At the same time, the distance between the upper and lower symmetrical guide rollers is increased, which greatly shortens the fabric feeding stroke and improves the convenience of fabric feeding.

[0013] 2. The setting of the guide roller can ensure the stability of the fabric fed between the two sets of napping rollers. BRIEF DESCRIPTION OF THE DRAWINGS
