Description

Technical Field

[0001] The utility model belongs to the technical field of ecological board equipment, and specifically relates to a top roller for a spinning frame. Background Art

[0002] A spinning frame is a spinning machine that drafts, twists, and winds semi-finished roving or sliver into bobbin yarn during the spinning process. The sliver is drafted and twisted into roving on a roving frame, the fibers are carded into combed sliver on a comber, the sliver is combined on a gill box, and the sliver structure is improved by drafting with a pin plate. The roving is further twisted into yarn on a ring spinning frame. The spinning frame is the main machine for spinning. The output and quality of the yarn are a comprehensive reflection of the advantages and disadvantages of each process in the spinning process. One of the significant advantages of the top roller pressure draft mechanism of the spinning frame over the traditional Nitto draft mechanism is that it can meet the requirements of heavy pressure process, which is conducive to improving the yarn quality and reducing yarn defects. Therefore, it has become an inevitable trend to equip new machines and retrofit old machines with the top roller draft mechanism. In order to give full play to the excellent process performance of the top roller draft mechanism, some understandings are now discussed from the aspect of setting the cross-sectional dimensions of the top roller draft mechanism for the design of new machines.

[0003] Referring to CN214060766U, a top roller for a spinning frame includes a bracket. A motor is provided at the bottom of the bracket. The driving end of the motor is fixedly connected to a transmission shaft. The end of the transmission shaft away from the motor is fixedly connected to a transmission gear disk. A gear chamber is provided inside the bracket, and the gear chamber communicates with the bottom of the bracket. Three stroke sleeves are evenly provided on one side of the inner side wall of the gear chamber, and the stroke sleeves vertically penetrate the inner side wall of the gear chamber and extend to the outer surface of the bracket. In the utility model, the pressure is applied through the mutual cooperation among the motor, the transmission gear disk, the threaded gear disk, the screw, the stroke chamber, and the stroke sleeve. Due to the use of gear-screw transmission, the pressure rollers receive the same force, which can effectively avoid different applied pressures. At the same time, the motor can be electrically connected to an external control box to achieve automatic pressure application when the equipment starts to run, which is very practical. When installing or disassembling the top roller of the existing spinning frame on or from the spindle of the spinning machine frame, generally, the spindle of the frame needs to be disassembled to complete the installation or disassembly of the top roller of the spinning frame, making the installation and disassembly of the top roller of the spinning frame very troublesome and time-consuming. Therefore, we introduce a new top roller for a spinning frame.

[0004] However, there are still the following problems. When installing or disassembling the top roller of the spinning frame on or from the spindle of the spinning machine frame, the spindle of the frame needs to be disassembled to complete the installation or disassembly of the top roller of the spinning frame, resulting in very troublesome, time-consuming, and laborious installation and disassembly of the top roller of the spinning frame.
