Description

Technical Field

[0001] This utility model relates to the field of textile equipment, and in particular to a textile roller that is easy to replace. Background Technology

[0002] The textile roller is a crucial component in textile machinery, primarily responsible for drafting, carding, and conveying. It utilizes tension, friction, and the transmission system to continuously transport, process, and finish the fabric according to design requirements. Specifically, the most common textile rollers are shaft-type structures, which exhibit hysteresis during the release of the woven yarn when driven by a resistance device.

[0003] The existing roller shaft has connecting caps 2 installed at both ends. When replacing the existing roller shaft, it is necessary to remove the connecting caps 2 from the frame. Therefore, the replacement process is actually a disassembly of three parts, which is very inconvenient.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0005] To address the aforementioned shortcomings, the purpose of this utility model is to provide a textile roller that is easy to replace. It can facilitate the connection between the roller shaft and the connecting cap through a telescopic connecting part that can be telescopically extended and retracted simultaneously, thereby further facilitating the replacement of the roller shaft. During the replacement process, there is no need to disassemble the connecting cap, which simplifies the roller shaft replacement steps and reduces the workload.

[0006] To achieve the above objectives, this utility model provides a replaceable textile roller, comprising a roller shaft and connecting caps connected to both ends thereto; wherein, the connecting caps are rotatably mounted on a frame; the connecting end of the roller shaft connected to the connecting cap is provided with a telescopic connecting part; the roller shaft has a space inside for accommodating the telescopic connecting parts; the two telescopic connecting parts extend and retract synchronously; the telescopic connecting parts are normally in an extended state; the connecting cap is provided with a through hole for convenient extrusion by a pressing component to switch states.

[0007] According to the present invention, a replaceable textile roller has two sets of telescopic connecting parts connected by a synchronous structure; the synchronous structure includes a rack disposed in the telescopic connecting part and a gear rotatably installed in the roller shaft space and meshing with the rack.

[0008] According to the present invention, the easily replaceable textile roller is installed by fitting the telescopic connecting part inside the connecting cap and rotating and positioning it through the positioning structure.

[0009] According to the present invention, the easily replaceable textile roller has a positioning structure that is a spline structure, which includes a keyway disposed on the outer wall of the telescopic connecting part and a key protrusion disposed on the inner wall of the connecting cap.

[0010] According to the present invention, the easily replaceable textile roller is further fitted with an auxiliary sleeve on the outer wall of the connecting cap, which can move along the axial direction of the connecting cap and connect with the telescopic connecting part when fixed.

[0011] According to the present invention, the easily replaceable textile roller is screwed to the telescopic connecting part.

[0012] This invention provides a replaceable textile roller, comprising a roller shaft and connecting caps at both ends. The connecting caps are rotatably mounted on a frame, typically via bearings and connected to a damper. The roller shaft has a telescopic connecting portion at the end connecting to the connecting caps; for ease of connection, the telescopic connecting portion also adopts a columnar shaft structure. The roller shaft has internal space for accommodating the telescopic connecting portions. The two telescopic connecting portions extend and retract synchronously; that is, when one telescopic connecting portion is pressed and retracted (retracted into the internal space of the roller shaft), the other telescopic connecting portion also naturally retracts. This invention facilitates the connection between the roller shaft and the connecting caps through synchronously extending and retractable connecting portions, further simplifying roller shaft replacement. During replacement, the connecting caps do not need to be disassembled, simplifying the roller shaft replacement process and reducing workload. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0020] See Figure 1 and Figure 2 This utility model provides a replaceable textile roller, which includes a roller shaft 1 and connecting caps 2 connected to its two ends; wherein, the connecting caps 2 are rotatably mounted on the frame. Normally, the textile thread is wound on the roller shaft 1, and the connecting caps 2 are mounted on the frame via bearings and connected to a damper (an existing structure).

[0021] The connecting end of the roller shaft 1 connected to the connecting cap 2 is provided with a telescopic connecting part 11. In this example, for ease of connection, the telescopic connecting part 11 also adopts a columnar shaft structure. The roller shaft 1 has a space inside for placing the telescopic connecting part 11. The two telescopic connecting parts 11 work synchronously. That is to say, when one telescopic connecting part 11 is pressed and is in a contracted state (contracted into the internal space of the roller shaft 1), the other telescopic connecting part 11 also naturally enters a contracted state.

[0022] Specifically, in this embodiment, the two sets of telescopic connecting parts 11 are connected by a synchronous structure;

[0023] See Figure 3 The synchronization structure includes a rack 12 disposed in the telescopic connecting part 11 and a gear 13 rotatably mounted in the space of the roller shaft 1 and meshing with the rack 12. Two sets of racks 12 are arranged opposite to the gear 13. The sidewall of the roller shaft 1 space limits the working state of the racks (the racks move along their extension direction). The length of the rack 12 depends on the moving distance of the telescopic connecting part 11. During operation, when one telescopic connecting part 11 is driven to move, the movement of the rack 12 connected to it drives the gear 13 to rotate, which further drives the other set of racks 12 and the telescopic connecting part 11 to move.

[0024] Normally, the telescopic connecting part 11 is in the extended state, which is the connected state of the telescopic connecting part 11; however, in this application, the connection of the gear 13 is installed with a torsion spring that drives the telescopic connecting part 11 to be in the extended state in the normal state.

[0025] The connecting cap 2 is provided with a through hole 21 to facilitate the extrusion of the extrusion member to the telescopic connecting part 11 for state switching. Figure 5 As shown in the figure, the extrusion part can be a push rod.

[0026] During installation, the telescopic connecting part 11 is fitted inside the connecting cap 2 and rotated for positioning by a positioning structure. The positioning structure is a spline structure, which includes a keyway on the outer wall of the telescopic connecting part 11 and a key protrusion on the inner wall of the connecting cap 2.

[0027] During the replacement process, it is only necessary to use the extrusion part (top rod) to insert into the through hole 21 to further extrude one of the telescopic connecting parts 11 into the retracted state. At this time, since the telescopic connecting part 11 is in a non-connected state, the roller shaft 1 can be separated from the connecting cap 2.

[0028] Conversely, during installation, first press the telescopic connecting part 11 of the roller shaft 1 into the retracted state, gradually align the axis of the roller shaft 1 with the connecting cap 2, and then release the press of the telescopic connecting part 11. The telescopic connecting part 11 will naturally return to the connected state (extended state) under the influence of the torsion spring.

[0029] See Figure 4 and Figure 5 Preferably, to increase the connection stability between the connecting cap 2 and the roller shaft 1, an auxiliary sleeve 6 is also fitted onto the outer wall of the connecting cap 2. This auxiliary sleeve 6 can move along the axial direction of the connecting cap 2 and connect to the telescopic connecting part 11 when fixed. The auxiliary sleeve 6 is screwed to the telescopic connecting part 11. After the telescopic connecting part 11 is connected to the connecting cap 2 through the positioning structure, the auxiliary sleeve 6 is further screwed to the telescopic connecting part 11 to achieve the purpose of auxiliary fastening.

[0030] In summary, this utility model provides a replaceable textile roller, including a roller shaft and connecting caps at both ends. The connecting caps are rotatably mounted on the frame, typically via bearings and connected to a damper. The roller shaft has a telescopic connecting part at the end connecting to the connecting cap; for ease of connection, the telescopic connecting part also adopts a columnar shaft structure. The roller shaft has internal space for housing the telescopic connecting parts. The two telescopic connecting parts extend and retract synchronously; that is, when one telescopic connecting part is pressed and in a retracted state (retracted into the internal space of the roller shaft), the other telescopic connecting part also naturally retracts. This utility model facilitates the connection between the roller shaft and the connecting cap through synchronously extending and retractable connecting parts, further simplifying roller shaft replacement. During replacement, the connecting caps do not need to be disassembled, simplifying the roller shaft replacement process and reducing workload.

[0031] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
