Description
Technical Field
[0001] The utility model relates to the technical field of textile equipment, in particular to an automatic feeding winding core structure for chemical fiber yarns. Background Art
[0002] Chemical fiber yarn, also known as chemical fiber yarn, is a chemical fiber yarn made from chemical fiber as raw material, and is a commonly used raw material in the textile field. During weaving, chemical fiber yarn needs to be fed to textile equipment for textile processing. During the feeding process of chemical fiber yarn, it is necessary to ensure that it does not get tangled, and the feeding is continuous. Therefore, it is necessary to guide and position the direction of chemical fiber yarn. At present, chemical fiber yarn is mostly fed by rollers, pagoda springs, guide tubes, etc. The above structure has guiding properties for chemical fiber yarn, but it cannot directly provide the power for feeding chemical fiber yarn. It is necessary to add additional stretching and traction mechanisms, and the structure is relatively complex. In addition, due to the presence of residual silk areas on the chemical fiber yarn during the feeding process, the residual silk needs to be removed in time. At present, manual removal is mostly used, which is inefficient. Chemical fiber yarn is also prone to knotting and broken silk due to improper tightness control during the feeding process, resulting in poor feeding, blockage, interruption and other problems. Therefore, it is urgent to provide a new type of automatic feeding core structure suitable for chemical fiber yarn. Utility Model Content
[0003] The technical problem to be solved by the utility model is: in order to overcome the deficiencies in the prior art, the utility model provides a chemical fiber thread automatic feeding winding core structure.
[0004] The technical solution to be adopted by the utility model to solve its technical problems is: a chemical fiber automatic feeding winding core structure, comprising an inner cylinder, an outer cylinder and a soft rubber part, wherein the inner cylinder and the outer cylinder are both hard rubber parts; the inner cylinder is inserted into the outer cylinder and connected and fixed by a snap-on structure; the upper end of the inner cylinder is provided with a flange edge, and on the flange edge at the connection with the outer cylinder, a partial area is provided with an arc-shaped groove along the circumferential direction, and the soft rubber part is embedded in the arc-shaped groove, and the lower end surface of the soft rubber part (that is, the end surface facing the outer cylinder) is provided with a plurality of soft rubber teeth along its length direction, and the soft rubber teeth are inclined outward (that is, inclined toward the outside of the winding core structure), and the inner side surface of the soft rubber teeth is pressed on the upper edge of the outer cylinder, and the end portion extends obliquely downward, so that an open gap is formed between the outer wall surface of the outer cylinder and the inner side surface of the extended part of the soft rubber teeth. When feeding, the chemical fiber is clamped in the gap and can move along the gap.
[0005] The size of the gap is limited by the inclination direction of the soft rubber teeth. Therefore, in order to achieve a smooth feeding effect, preferably, the angle α between the inner side surface of the soft rubber teeth and the axial direction is in the range of 60°-70°, and the angle β between the outer side surface of the soft rubber teeth and the radial direction is in the range of 55°-65°.
[0006] Furthermore, guide angle structures are provided between the soft rubber parts at both ends of the slit and the outer cylinder wall. By adding a guide angle at the slit inlet, the chemical fiber yarn is smoothly introduced into the slit and clamped, and a guide angle is provided at the slit outlet to facilitate the chemical fiber yarn to smoothly enter the next process.
[0007] In order to allow the chemical fiber to quickly enter the gap, it is further preferred that the outer wall surface of the outer cylinder near the gap is a tapered surface. A V-shaped notch is formed between the tapered surface of the outer cylinder and the outer side surface of the soft rubber teeth, which can initially guide the chemical fiber to facilitate its rapid entry into the gap.
[0008] Furthermore, the buckle structure includes a sub-buckle and a female buckle. The sub-buckle is an "arrow-shaped" protrusion set on the bottom edge of the inner wall of the outer tube, and the female buckle is a T-shaped notch set on the bottom edge of the outer wall of the inner tube. When connected, the sub-buckle is inserted into the female buckle and clamped, so that the inner tube and the outer tube are inserted and fixed through the sub-buckle. When disassembling, it is also convenient to directly pull the inner tube out of the outer tube with force. The sub-buckle and the female buckle are set in pairs, which can be one pair or multiple pairs, according to needs.
[0009] Furthermore, the connection between the inner cylinder and the outer cylinder is provided with an anti-mistake boss. The addition of the anti-mistake boss can avoid assembly errors when the inner cylinder and the outer cylinder are installed, and can also make the chemical fiber yarn smoothly transferred to the middle position of the winding core.
[0010] Furthermore, two tool avoidance grooves are provided on one end of the outer cylinder near the gap. When there are residual threads in the chemical fiber thread at the gap, the residual threads in the gap at the corresponding position of the tool avoidance groove can be cut by the tool and then taken away.
[0011] Furthermore, the soft rubber teeth are inclined along the spiral in the axial direction, and the inclination direction is opposite to the rotation direction of the winding core.
[0012] Preferably, the inclination angle γ of the soft rubber teeth is in the range of 75°-85°. The soft rubber and the chemical fiber yarn are relatively rubbed to clamp the chemical fiber yarn, so that the chemical fiber yarn is pulled under the action of friction force to achieve an automatic feeding effect.
[0013] Preferably, the inner cylinder and the soft rubber part are fixedly connected by injection molding or bonding.
[0014] The beneficial effects of the utility model are as follows: the utility model provides an automatic feeding winding core structure for chemical fiber yarns, wherein (1) the soft rubber parts and the hard rubber parts are spliced together to realize an infinitely small gap, and the chemical fiber yarns can be stably clamped; (2) the inclination direction of the soft rubber teeth is opposite to the rotation direction, and the chemical fiber yarns are clamped by the relative friction between the soft rubber and the chemical fiber yarns, thereby achieving the effect of automatic feeding; (3) after the chemical fiber yarns are taken away, when it is necessary to clean the residual yarns in the gap, compressed air can be blown in along the inclination direction of the soft rubber teeth, and the residual yarns can be cleaned smoothly, and the cleaning is convenient and quick; (4) the inner tube and the soft rubber parts are bonded together by double-color injection molding, and then assembled and fixed with the outer tube by buckles, which has a simple structure, efficient assembly, and convenient disassembly.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention, and directions and references (e.g., up, down, left, right, etc.) may only be used to help describe the features in the drawings. Therefore, the following specific embodiments are not to be taken in a limiting sense, and the scope of the subject matter claimed is limited only by the attached claims and their equivalents.
[0032] In this embodiment, for the convenience of structural description, the side provided with the soft rubber part 4 is regarded as the upper end, the side facing the center line is regarded as the inner side, and the side away from the center line is regarded as the outer side.
[0033] like Figure 1-Figure 14 As shown, the utility model is a chemical fiber automatic feeding winding core structure, comprising an inner cylinder 1, an outer cylinder 2 and a soft rubber part 4, wherein the inner cylinder 1 and the outer cylinder 2 are both hard rubber parts; the inner cylinder 1 and the soft rubber part 4 are fixedly connected by injection molding or bonding. In this embodiment, in order to facilitate the identification of the soft rubber part 4, the inner cylinder 1 and the soft rubber part 4 are of different colors. The inner cylinder 1 is inserted into the outer cylinder 2 and is connected and fixed by a snap-on structure 3. In order to ensure a stable connection between the inner cylinder 1 and the outer cylinder 2, a plurality of strip convex ribs 2.1 parallel to the axis are distributed circumferentially on the outer wall of the inner cylinder 1, and strip grooves 2.1 that match the strip convex ribs 2.1 are provided on the inner wall of the outer cylinder 2. When installed, the strip convex ribs 2.1 are inserted into the strip grooves 2.1. As shown Figure 1 , Figure 7 and Fig. 9As shown, the buckle structure 3 includes a sub-buckle 3.2 and a female buckle 3.1. The sub-buckle 3.2 is an "arrow-shaped" protrusion arranged at the bottom edge of the inner wall of the outer tube 2, and the female buckle 3.1 is a T-shaped notch arranged at the bottom edge of the outer wall of the inner tube 1. When connected, the sub-buckle 3.2 is inserted into the female buckle 3.1 and clamped, so that the inner tube 1 and the outer tube 2 are inserted and fixed by the sub-buckle. When disassembling, it is also convenient, and the inner tube 1 can be directly pulled out of the outer tube 2 by force. The sub-buckle 3.2 and the female buckle 3.1 are arranged in pairs, which can be one pair or multiple pairs, and are arranged according to needs. In this embodiment, four pairs of sub-buckles 3.1 are arranged, and the four pairs of sub-buckles 3.1 are evenly arranged circumferentially.
[0034] like Figure 2 , Fig.10 and Fig.11 As shown, the upper end of the inner cylinder 1 is provided with a flange 1.1, and on the flange 1.1 at the connection with the outer cylinder 2, there is a partial area with an arc groove along the circumferential direction, and the soft rubber part 4 is embedded in the arc groove. A plurality of soft rubber teeth 4.1 are provided on the lower end surface of the soft rubber part 4 (i.e., the end surface facing the outer cylinder 2) along its length direction, and the soft rubber teeth 4.1 have an inner side surface 4.2, an outer side surface 4.3, a front side surface 4.4 and a rear side surface 4.5. The soft rubber teeth 4.1 are inclined outwardly (i.e., inclined toward the outside of the winding core structure), and the inner side surface 4.2 of the soft rubber teeth 4.1 is pressed on the upper edge of the outer cylinder 2, and the end portion extends obliquely downward, so that a space as shown in the figure is formed between the outer wall surface of the outer cylinder 2 and the inner side surface 4.2 of the extended portion of the soft rubber teeth 4.1. Fig.11 The open slit 7 shown in the figure, when feeding, the chemical fiber yarn is clamped in the slit 7 and can move along the slit 7. Fig.11 As shown, the angle α between the inner side 4.2 of the soft rubber tooth 4.1 and the axial direction is in the range of 60°-70°, and the angle β between the outer side 4.3 of the soft rubber tooth 4.1 and the radial direction is in the range of 55°-65°. In this embodiment, the preferred angle α is 62.49°, and the angle β is 59.61°. Fig.13 As shown, the soft rubber teeth 4.1 are inclined along the spiral in the axial direction, and the inclination direction is opposite to the rotation direction of the winding core. Preferably, the inclination angle γ of the soft rubber teeth 4.1 is in the range of 75°-85°. The soft rubber and the chemical fiber yarn are relatively rubbed to clamp the chemical fiber yarn, so that the chemical fiber yarn is pulled under the action of friction, thereby achieving an automatic feeding effect.
[0035] like Figure 8 and Fig.14As shown, guide angle structures 6 are provided between the soft rubber parts 4 at both ends of the slit 7 and the wall surface of the outer cylinder 2. By adding a guide angle at the entrance of the slit 7, the chemical fiber yarn is smoothly introduced into the slit 7 and clamped, and a guide angle is set at the exit of the slit 7 to facilitate the chemical fiber yarn to smoothly enter the next process. Two tool avoidance grooves 2.2 are provided on one end of the outer cylinder 2 close to the slit 7. When there are residual threads in the chemical fiber yarn at the slit 7, the residual threads in the slit 7 at the corresponding position of the tool avoidance groove 2.2 can be hooked off by a tool, and then the residual threads can be taken away.
[0036] like Figure 5 and Fig.11 As shown, the connection between the inner cylinder 1 and the outer cylinder 2 is also provided with an anti-mistake boss 5. The addition of the anti-mistake boss 5 can avoid assembly errors when the inner cylinder 1 and the outer cylinder 2 are installed, and can also smoothly transfer the chemical fiber yarn to the middle position of the winding core.
[0037] like Fig.14 As shown, the outer wall surface of the outer cylinder 2 near the slit 7 is a conical surface 2.3. A V-shaped notch is formed between the conical surface 2.3 of the outer cylinder 2 and the outer side surface 4.3 of the soft rubber teeth 4.1, which can be used to initially guide the chemical fiber yarn to facilitate its rapid entry into the slit 7.
[0038] Working principle:
[0039] like Fig.14 As shown, the chemical fiber yarn enters from the guide angle structure 6 on one side of the foolproof boss 5, that is, the feeding direction of the chemical fiber yarn is from left to right, and the rotation direction of the winding core is from right to left, which is opposite to the direction of the chemical fiber yarn. The movement of the chemical fiber yarn generates friction with the soft rubber part 4 and the outer cylinder 2. Under the action of the tapered surface 2.3 of the outer cylinder 2, the chemical fiber yarn is guided into the slit 7, so that the chemical fiber yarn is clamped between the soft rubber teeth 4.1 of the soft rubber part 4 and the tapered surface 2.3, thereby driving the automatic feeding of the chemical fiber yarn.
[0040] During the feeding process, if residual silk is detected on the chemical fiber yarn, the residual silk is moved to the position between the two tool avoidance grooves 2.2, and then the tool is started to cut the residual silk and take it away to remove the residual silk.
[0041] When rotating at high speed, the chemical fiber filaments are clamped off and automatic loading is completed. After the chemical fiber filaments are taken away by the next workstation, compressed air can be used to eat away the residual filaments in the 7 gaps to achieve recycling.
[0042] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without departing from the scope of the utility model through the above description. The technical scope of this utility model is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
