Description

Technical Field

[0001] The utility model relates to the technical field of open-end spinning, in particular to a device for disassembling and assembling a top roller. Background Technique

[0002] Open-end spinning is a new spinning technology that uses air flow to condense and twist fibers in a spinning cup rotating at high speed to output yarn. It mainly relies on multiple components such as a combing roller, a spinning cup, and a false-twist device. Open-end spinning has the advantages of high speed, large yarn package, wide adaptability, simple mechanism, and no need for spindles, rings, and travellers, and can increase the output of fine yarn several times. After the open-end spinning top roller is used for a period of time, grooves will appear on its surface due to wear, affecting the yarn quality. Therefore, the top roller needs to be replaced.

[0003] For example, the utility model with the application number CN202022570911.1 discloses a device for disassembling and assembling an open-end spinning top roller. This utility model is set to drive the clamping unit and the top roller to rotate by the disassembly unit, so that the top roller is separated from the main shaft to complete the disassembly of the top roller. This disassembly method is simple, convenient, not easy to damage the top roller bearing, improves work efficiency, and extends the service life of the top roller. However, in the actual use process, the first clamping part only contacts half of the top roller, resulting in the problem that the disassembly effect is easily affected due to uneven force on the top roller when applying force.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies to provide a device for disassembling and assembling a top roller. Content of the Utility Model

A guiding frame is arranged on one side of the fixed seat. The limiting component is arranged on the upper part of the fixed seat. The limiting component includes a rotating seat, a shifting block, a buckle, a positioning ear, a limiting plate, and a limiting groove. The upper end of the fixed seat is rotatably connected to the rotating seat, and one side upper end of the fixed seat is rotatably connected to the shifting block. The outside of the shifting block is rotatably connected to the buckle, and a positioning ear is arranged at the upper end of the buckle. Limiting plates are arranged inside both the fixed seat and the rotating seat, and a limiting groove is opened on one side of the limiting plate.

[0007] Furthermore, the outside of one end of the guiding frame is slidably connected to an adjusting plate, and an adjusting screw is threadedly connected inside the lower end of the adjusting plate, and a pushing screw is threadedly connected inside the upper end of the adjusting plate.

[0008] Furthermore, the adjusting screw is rotatably connected to the fixed seat, and the fixed seat is U-shaped.

[0009] Furthermore, replacement components are provided on one side of both the fixed seat and the rotating seat. The replacement components include a connecting plate, a magnet, and a bolt. A magnet is fixed in the middle of one side of the connecting plate, and bolts are connected to the upper and lower ends of one side of the connecting plate.

[0010] Furthermore, the positioning ear is fixedly connected to the rotating seat, and the connecting plates are symmetrically distributed about the center line of the rotating seat.

[0011] Furthermore, the replacement components further include positioning holes and positioning grooves. Positioning holes are provided at the four ends of the limiting plate, and positioning grooves are provided inside the fixed seat and the rotating seat.

[0012] Furthermore, the inner diameter of the positioning hole is equal to the diameter of the bolt, and the bolt is slidably connected to the fixed seat.

[0013] Furthermore, the width of the limiting plate is adapted to the width of the positioning groove, and the limiting plate is slidably connected to the bolt through the positioning hole.

[0014] The present utility model provides a device for disassembling and assembling a roller, having the following beneficial effects:

[0015] 1. Through the arrangement of the limiting components in the present utility model, the toggle block can be first toggled to drive the buckle to move upward, separating it from the positioning ear, so as to open the rotating seat and make the limiting plate inside the fixed seat fit against the side of the roller. Then, the rotating seat and the fixed seat are butted, and the buckle is used to lock the positioning ear by means of the toggle block, so that the rotating seat can be positioned, enabling both the upper and lower limiting plates to fit against the roller outside the main shaft, thereby making the force on the side of the roller uniform and avoiding damage to the main shaft due to uneven force.

[0016] 2. Through the arrangement of the replacement components in the present utility model, when it is necessary to replace the limiting plate with a corresponding-shaped limiting groove according to the shape of the roller, only by pulling the connecting plate forcefully can the bolt be separated from the limiting plate, so as to slide the limiting plate out of the positioning groove. And during installation, the positioning groove can be used to quickly position the limiting plate in the horizontal direction, and then the bolt is inserted into the positioning hole to position the limiting plate in the vertical direction. Then, the magnet can adsorb the iron fixed seat or rotating seat, thereby quickly positioning the position of the connecting plate. Therefore, no other tools are needed during replacement, which is beneficial to improving the convenience during use. BRIEF DESCRIPTION OF THE DRAWINGS
