Abstract
Description
Technical Field
[0001] This utility model specifically relates to the field of rubber rollers for spinning frames, and more specifically to a rubber roller for compact spinning frames with a long service life. Background Technology
[0002] Compact spinning frame is an advanced textile equipment used for spinning yarn. By improving the drafting and twisting methods of traditional ring spinning, it makes the yarn structure more compact, less hairy, and stronger. Compact spinning further shrinks and gathers the drafted fiber slivers through negative pressure or mechanical control in the gathering zone, reducing the width, and then twisting, making the yarn structure more compact and the surface smoother.
[0003] The compact spinning machine is equipped with rubber rollers, which work in conjunction with the rollers. By applying appropriate pressure, the rollers hold the fiber sliver and stretch the fiber under the stretching action of the rollers, thus achieving the fiber stretching process and controlling the fineness of the yarn.
[0004] However, in practice, it has been noted that most rubber rollers currently use a metal core with a rubber coating attached to it. The yarn moves on the outside of the roller for a long time, and the high-speed friction at the connection between the metal core and the support plate can damage the end of the metal core. This requires frequent disassembly and maintenance of the roller, and the disassembly process is cumbersome, making it impossible to replace the roller quickly, which affects the replacement efficiency of the roller. Utility Model Content
[0005] The purpose of this invention is to provide a high-performance rubber roller for a compact spinning machine with a long service life. One end of the roller assembly is equipped with a supporting bearing, while the other end has a removable end cap that mates with a side support plate. The removable end cap is fixedly connected to the side support plate via a screw-locking fastener, facilitating the disassembly of the roller assembly and the quick replacement of the outer rubber sleeve, thereby extending the service life of the roller assembly. This addresses the technical problems mentioned in the background section.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A long-life compact spinning machine rubber roller includes a spinning machine body, side support plates are symmetrically fixedly connected to the top of the spinning machine body, rubber roller assemblies are arranged in a rectangular array between the symmetrical side support plates, and holes corresponding to the rubber roller assemblies are opened on the side support plates.
[0008] The rubber roller assembly includes a support spindle, with a mounting bearing and a removable end cap installed at each end of the support spindle. The mounting bearing is interference-fitted at the end of the support spindle near the protective housing, and the outer ring of the mounting bearing is interference-fitted with a hole in the side support plate.
[0009] As a further technical solution of this utility model, the detachable end cap includes a fixed bushing inserted into a hole in the side support plate, and a limiting baffle is integrally provided at the end of the fixed bushing away from the support spindle, and U-shaped slots are symmetrically provided on the limiting baffle.
[0010] As a further technical solution of this utility model, each of the U-shaped slots is fitted with a spiral locking buckle, wherein the spiral locking buckle includes two threaded crossbars fixedly connected to the side of the side support plate, and the threaded crossbars pass through the U-shaped slots and are threaded with an internal threaded locking cap.
[0011] As a further technical solution of this utility model, the internal thread locking cap is attached to the side of the limiting baffle away from the side support plate, and an inclined handle is fixedly connected above the internal thread locking cap.
[0012] As a further technical solution of this utility model, the outer side of the supporting mandrel is fixedly connected with an outer rubber sleeve in a rectangular array.
[0013] The fixed bushing has an interference fit with a fixed bearing, and the end of the supporting spindle away from the bearing is interference fitted with the inner ring of the fixed bearing.
[0014] As a further technical solution of this utility model, a fixing rod is fixedly connected to the top of the side support plate, and leaf spring rockers are installed on the fixing rod in a rectangular array. Moreover, a yarn guide corresponding to the outer rubber sleeve is fixedly connected to the end away from the leaf spring rockers.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] In this invention, a fixed bushing is inserted into a hole in a side support plate, and a limiting baffle at the end of the fixed bushing acts as a stop. Furthermore, the fixed bearing in the fixed bushing is interference-fitted with the end of the support spindle, which supports the end of the support spindle and facilitates the disassembly of the support spindle by the operator, thereby facilitating the quick replacement of the outer rubber sleeve after the support spindle is removed.
[0017] In this utility model, while the limiting baffle is installed on the side of the side support plate, the threaded crossbar is located in the U-shaped groove on the limiting baffle, thereby positioning the limiting baffle and preventing the limiting baffle from rotating circumferentially. Then, the limiting baffle is fixed to the side of the side support plate by the threaded engagement between the threaded crossbar and the internal thread locking cap.
[0018] In this invention, a mounting bearing is provided at the end of the support spindle away from the fixed bearing. Through the interaction of the mounting bearing and the fixed bearing, the support spindle is installed on the inner side of the side support plate without affecting the normal rotation of the support spindle. Moreover, the separate design of the support spindle and the outer rubber sleeve further facilitates the quick replacement of the outer rubber sleeve, thereby extending the service life of the rubber roller assembly.
