Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, and more specifically, to a novel roller seat. Background Technology

[0002] The main task of a ring spinning frame is to process roving into fine yarn of a certain linear density that meets national quality standards or user requirements through drafting, twisting, and winding. The bottom pin is a specialized component of the drafting system of the ring spinning frame, installed on the roller seat. Currently, there are two main specifications of bottom pins for different spinning processes, corresponding to two specifications of roller seats. Each time the bottom pin is replaced, the matching roller seat must also be replaced. The roller seat also houses rollers, roller bearings, rubber rollers, and other components, making each disassembly and reassembly of the roller seat very troublesome, time-consuming, and labor-intensive.

[0003] Therefore, it is necessary to improve the existing technology. Utility Model Content

[0005] A novel roller seat includes a base. The top surface of the base is provided with an arc-shaped groove for fixing a bearing. The axis of the arc-shaped groove is arranged along the front-back direction. The top surface of the base located on the left side of the arc-shaped groove is provided with a first lower pin groove arranged along the front-back direction. The bottom wall of the first lower pin groove is provided with a second lower pin groove arranged along the front-back direction. The second lower pin groove divides the bottom wall of the first lower pin groove into left and right parts. The left side wall of the second lower pin groove and the left part of the bottom wall of the first lower pin groove form a stepped structure. The right side wall of the second lower pin groove and the right part of the bottom wall of the first lower pin groove form a stepped structure. The top surface of the base located on the right side of the arc-shaped groove is provided with a third lower pin groove arranged along the front-back direction.

[0006] Preferably, the top surface of the base located on the left side of the arc-shaped groove is higher than the top surface of the base located on the right side of the arc-shaped groove.

[0007] Preferably, the left-right width of the bottom wall of the first lower pin slot is greater than the left-right width of the bottom wall of the right lower pin slot.

[0008] Preferably, the bottom wall of the second lower pin groove is higher than the bottom wall of the third lower pin groove.

[0009] Preferably, the cross-sections of the first lower pin slot, the second lower pin slot, and the third lower pin slot are all rectangular.

[0010] Preferably, the bottom surface of the base is provided with a limiting groove arranged in the left-right direction, which serves to limit the base when it is installed on the frame.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This utility model discloses a novel roller seat that can be adapted to two existing specifications of lower pins. When replacing the lower pin, it is not necessary to disassemble the roller seat; only the lower pin needs to be replaced, which saves time and effort and is highly efficient.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] like Figure 1 As shown, a preferred embodiment of this utility model provides a novel roller seat.

[0021] The new roller seat includes a base 1, which is block-shaped. An arc-shaped groove 2 is provided on the top surface of the base 1, and the axis of the arc-shaped groove 2 is arranged along the front-back direction. The arc-shaped groove 2 is used to install the roller bearing.

[0022] The top surface of the base located on the left side of the arc-shaped groove 2 is higher than the top surface of the base located on the right side of the arc-shaped groove 2. A first lower pin groove 3 is provided on the top surface of the base located on the left side of the arc-shaped groove 2, arranged in the front-back direction. The first lower pin groove 3 is embedded and has a rectangular cross-section. A second lower pin groove 4 is provided on the bottom wall of the first lower pin groove 3, arranged in the front-back direction. The second lower pin groove 4 is embedded and has a rectangular cross-section.

[0023] The second lower pin groove 4 divides the bottom wall of the first lower pin groove 3 into left and right parts. The left side wall of the second lower pin groove 4 and the left part of the bottom wall of the first lower pin groove 3 form a stepped structure. At the same time, the right side wall of the second lower pin groove 4 and the right part of the bottom wall of the first lower pin groove 3 form a stepped structure.

[0024] Furthermore, the left-right width of the bottom wall of the first lower pin groove 3 is greater than the left-right width of the bottom wall of the right side of the first lower pin groove 3.

[0025] A third lower pin groove 5 is provided on the top surface of the base located on the right side of the arc-shaped groove 2, which is arranged in the front-to-back direction. The third lower pin groove 5 is embedded and has a rectangular cross-section.

[0026] Furthermore, the bottom wall of the second lower pin groove 4 is higher than the bottom wall of the third lower pin groove 5.

[0027] like Figure 2-3 As shown, the roller seat described above can be adapted to the two existing specifications of the lower pin 6. When replacing the lower pin 6, it is not necessary to disassemble the roller seat; only the lower pin 6 needs to be replaced, which saves time and effort and is highly efficient.

[0028] In addition, the bottom surface of the base 1 is provided with a limiting slot 7 arranged in the left and right direction, which plays a limiting role in the installation of the base on the frame 8, making installation convenient and the use effect good.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
