Description

Technical Field

[0001] This utility model relates to an auxiliary device for fabric processing, and in particular to a fabric feeding device. Background Technology

[0002] After the initial processing of the fabric is completed, in order to save space, the fabric is usually coiled into a cylindrical shape and packaged for downstream companies. The companies then cut the fabric into the required size or perform other types of processing. Before processing, the coiled fabric is placed on the unloading rack. When the front end of the fabric is pulled, the coiled fabric rotates and is released.

[0003] However, in existing fabric cutting equipment, the coiled fabric is prone to shifting horizontally during the cutting process, which causes the cutting angle of the fabric to deviate, resulting in wrinkles and affecting subsequent fabric processing. Utility Model Content

[0004] Therefore, it is necessary to provide a fabric feeding device to address the shortcomings of existing technologies.

[0005] A fabric feeding device includes a feeding frame and a fabric cylinder. The fabric cylinder includes a support roller and a fabric body. The support roller of the fabric cylinder is mounted on the feeding frame. The support roller has slots at both ends, which are distributed on the outer circumferential surface of the support roller. The feeding frame includes a frame body and a positioning seat mounted on the frame body. The positioning seat includes a support frame, a plurality of positioning rollers, and a plurality of bearings. The inner ring of the bearing is mounted on the positioning roller, and the positioning roller is mounted on the support frame. The outer rings between the bearings form a locking space. The size of the locking space matches the inner diameter of the support roller at the slot position. When installing the fabric cylinder, the outer ring of the bearing is inserted into the slot on the support roller, and the outer circumference of the bottom of the slot is in contact with the outer ring of the bearing.

[0006] In one embodiment, a plurality of guide plates are also included. The guide plates are mounted on the frame body and located on one side of the positioning seat. The guide plates are provided with guide surfaces that are inclined downwards, and the bottom of the guide surfaces is located near the entrance of the card slot space.

[0007] In one embodiment, the width of the slot gradually narrows from the outside to the inside, and the slot walls on both sides of the slot form inclined guide surfaces.

[0008] In one embodiment, there are two positioning seats, which are mounted on the sides of the frame body and are positioned opposite each other in the horizontal direction.

[0009] In one embodiment, the positioning seat further includes several bushings and several limiting plates. The bushings are mounted on the positioning roller and limit the bearing in the horizontal direction. The limiting plates are inserted into the positioning roller and limit the positioning roller in the horizontal direction.

[0010] In one embodiment, the support frame is provided with two support plates arranged opposite to each other. The support plates are provided with positioning grooves that extend inward at an angle. The positioning grooves on the two support plates are arranged opposite to each other in the horizontal direction, forming a positioning space between the two support plates. The support plates are provided with a plurality of positioning holes, which surround the outside of the positioning grooves. The bushings are divided into a plurality of groups, and the inner rings of the bearings are located between the bushings in the same group. The positioning roller passes through the positioning holes on the support plates, the bushings, and the inner rings of the bearings.

[0011] In one embodiment, the outer peripheral surface of the positioning roller near both ends is provided with grooves, the limiting plate is provided with notches, the two ends of the positioning roller and the grooves on the positioning roller extend from the two support plates, and the notch portion of the limiting plate is inserted into the groove from one side.

[0012] In one embodiment, the outer ring of the bearing extends between the positioning grooves of the two support plates.

[0013] The beneficial effects of this fabric feeding device are as follows: by setting a groove on the support roller and setting several bearings on the positioning seat, when installing the fabric ring cylinder, the outer ring of the bearing is inserted into the groove on the support roller, and the outer periphery of the bottom of the groove is simultaneously in contact with the outer rings of all the bearings, which effectively reduces the resistance when the support roller rotates and effectively prevents the fabric ring cylinder from shifting during rotation, making it highly practical.

[0025] Please see Figures 1 to 5 This utility model provides a fabric feeding device, including a feeding frame 100 and a fabric cylinder 200. The fabric cylinder 200 includes a support roller 220 and a fabric body 210 wound around the support roller 220. The support roller 220 of the fabric cylinder 200 is mounted on the feeding frame 100. The support roller 220 is provided with slots 221 at both ends. The slots 221 are distributed on the outer peripheral surface of the support roller 220. The width of the slots 221 gradually narrows from the outside to the inside. The slot walls on both sides of the slots 221 form inclined guide surfaces 222.

[0026] The unloading rack 100 includes a rack body 10 and positioning seats 20 mounted on the rack body 10. There are two positioning seats 20, which are mounted on the rack body 10 at the two sides and are arranged opposite each other in the horizontal direction. Each positioning seat 20 includes a support frame 30, a plurality of positioning rollers 60, a plurality of bearings 40, a plurality of bushings 50, and a plurality of limiting pieces 70. In this embodiment, there are three positioning rollers 60 and three bearings 40. The positioning rollers 60 and bearings 40 correspond one-to-one. The inner ring of the bearing 40 is mounted on the positioning roller 60. The positioning roller 60 is mounted on the support frame 30. The bushings 50 are mounted on the positioning rollers 60 and limit the bearings 40 in the horizontal direction. The limiting pieces 70 are inserted into the positioning rollers 60 and limit the positioning rollers 60 in the horizontal direction.

[0027] Specifically, the support frame 30 is provided with two opposing support plates 31. Each support plate 31 has an inwardly extending positioning groove 311. The positioning grooves 311 on the two support plates 31 are arranged opposite each other in the horizontal direction, forming a positioning space between the two support plates 31. Each support plate 31 is provided with a plurality of positioning holes 312, which surround the outside of the positioning grooves 311. The positioning holes 312 on the two support plates 31 correspond one-to-one and are aligned with each other. The outer peripheral surface of the positioning roller 60 near both ends is provided with grooves 61, and the limiting piece 70 is provided with notches 71.

[0028] During assembly, the bushings 50 are divided into several groups. The bearing 40 and a group of bushings 50 are fitted together and positioned between the two support plates 31. The inner ring of the bearing 40 is positioned between the bushings 50 in the same group. The positioning roller 60 passes through the positioning hole 312 on the support plate 31, the bushing 50, and the inner ring of the bearing 40. The two ends of the positioning roller 60 and the groove 61 on the positioning roller 60 extend out from the two support plates 31. The notch 71 of the limiting plate is inserted into the groove 61 from one side, and the limiting plate is then fixed to the support plate 31 with screws. The outer ring of the bearing 40 extends into the positioning groove 311 between the two support plates 31. The outer rings on different bearings 40 form an inclined downward extending locking space 90. The size of the locking space 90 matches the inner diameter of the support roller 220 at the position of the locking groove 221.

[0029] When the support roller 220 passes through the two positioning grooves 311 and is placed in the locking space 90, the outer periphery of the bottom position of the locking groove 221 is in contact with the outer rings of all the bearings 40. When the front end of the fabric is dragged or the support roller 220 and the fabric body 210 wrapped around the support roller 220 are rotated by an external drive mechanism, the outer rings of the bearings 40 rotate, making it easier to rotate the support roller 220 and the fabric body 210 wrapped around the support roller 220. Furthermore, the outer rings of the bearings 40 are locked into the locking grooves 221 on the support roller 220, effectively preventing the fabric cylinder 200 from shifting during rotation. The inclined guide surfaces 222 on both sides of the locking groove 221 facilitate locking the outer rings of the bearings 40 into the locking grooves 221 on the support roller 220.

[0030] In addition, this utility model also includes several guide plates 80. The guide plates 80 are installed on the frame body 10 and located on one side of the positioning seat 20. The guide plates 80 are provided with guide surfaces 81, which are inclined downwards. The bottom of the guide surfaces 81 is located near the entrance of the locking space 90. By setting the guide plates 80, when installing the fabric cylinder 200, the support roller 220 of the fabric cylinder 200 slides over the guide surfaces 81 and falls into the locking space 90, thereby realizing the quick installation of the support roller 220 of the fabric cylinder 200 in the locking space 90. Then, the position of the fabric cylinder 200 is adjusted horizontally so that the outer ring of the bearing 40 is engaged in the groove 221 on the support roller 220.

[0031] The beneficial effects of this fabric feeding device are as follows: by setting a groove 221 on the support roller 220 and setting several bearings 40 on the positioning seat 20, when the fabric ring 200 is installed, the outer ring of the bearing 40 is inserted into the groove 221 on the support roller 220, and the outer periphery of the bottom position of the groove 221 is simultaneously in contact with the outer ring of all the bearings 40, which effectively reduces the resistance when the support roller 220 rotates, and at the same time effectively prevents the fabric ring 200 from shifting during rotation, making it highly practical.

[0032] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0033] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
