Description
Technical Field
[0001] The utility model relates to a ring spinning frame, in particular to a drafting roller spacing adjustment tool specially used for the ring spinning frame. Background Art
[0002] The drafting roller is the main part of the drafting mechanism of the ring spinning frame. The drafting roller is a steel slender shaft part with grooves, knurling or smooth surface on the outer circle. The drafting roller is configured along the entire length of the ring spinning frame and is connected into a whole row by several single rollers. The existing ring spinning frame is equipped with three rows of drafting rollers, namely the front roller, the middle roller and the rear roller. The ring spinning frame drafts the yarn through the three rows of drafting rollers to produce a certain amount of yarn.
[0003] The drafting rollers of existing ring spinning machines are all rotatably mounted in the bearing seat through bearings, the bearing seat is mounted on the roller seat, the front roller bearing seat is fixedly connected to the roller seat, and the middle roller bearing seat and the rear roller bearing seat are detachably slidably connected to the roller seat through fastening bolts and guide rail grooves. There is a distance between the front roller, middle roller and rear roller of the ring spinning machine, which is called the roller gauge. The roller gauge is one of the main spinning process parameters of the ring spinning machine and is adjusted according to the length of the spinning fiber. The existing roller spacing adjustment method is as follows: loosen the fastening bolts on the middle roller bearing seat and the rear roller bearing seat, so that the middle roller bearing seat and the rear roller bearing seat can slide and translate along the guide rail groove on the roller seat, first use the front roller as the fixed reference roller, adjust the roller spacing between the front roller and the middle roller, insert a suitable process spacing block between the front roller and the middle roller, and the worker manually knocks the sliding middle roller that needs to be adjusted to make it close to the process spacing block. After adjusting appropriately, tighten the fastening bolts on the middle roller bearing seat to fix the middle roller bearing seat and the roller seat, and then use the adjusted and fixed middle roller as the fixed reference roller to adjust the roller spacing between the middle roller and the rear roller, insert a suitable process spacing block between the middle roller and the rear roller, and the worker manually knocks the sliding rear roller that needs to be adjusted to make it close to the process spacing block. After adjusting appropriately, tighten the fastening bolts on the rear roller bearing seat to fix the rear roller bearing seat and the roller seat. The existing roller gauge adjustment operation has the following three shortcomings in practical application: first, in order to adjust the roller gauges of different distances, the existing process gauge blocks are of different thicknesses and numerous in number, which makes it inconvenient to select when using; second, the existing process gauge blocks are rectangular block parts, which are easy to fall off when inserted between the rollers. When adjusting, the worker must knock the roller with one hand to make it close to the process gauge block, and at the same time, tighten the fastening bolt with the other hand to fix the bearing seat. The knocking of the roller to adjust the roller gauge and the tightening of the fastening bolt must be performed at the same time, which is not convenient to operate, and there are problems such as inaccurate adjustment and loose tightening that require repeated operations; third, because the drafting rollers are configured along the entire length of the ring spinning frame, multiple workers are required to operate in unison during adjustment. Now, with the continuous increase in the number of spindles in the ring spinning frame, the length of the drafting rollers is also increasing. When adjusting the roller gauges of the increasingly longer drafting rollers, more workers are required to operate in unison, which wastes manpower. Summary of the invention
