Abstract
The invention relates to a finish machining mechanism for feed plates of rotor spinning machinery. The mechanism comprises a middle shaft and a large shaft parallel to each other. The large shaft is driven by a motor. A wide abrasive belt is wound between the middle shaft and the large shaft. A small shaft parallel to the middle shaft is arranged beside the middle shaft. The distance between the axis of the small shaft and the axis of the middle shaft is smaller than the length of a feed plate. The radius of the small shaft is smaller than that of a shaft hole. The sum of the radius of the middle shaft and the thickness of the abrasive belt is equal to the radius of an operating arc segment of the feed plate. The invention further discloses a machining method of the finish machining mechanism for feed plates of rotor spinning machinery. The method includes the steps of a, sleeving the shaft hole of the feed plate on the small shaft, and starting the motor; b, pushing the other end of the feed plate onto the abrasive belt on the middle shaft with hands, allowing the feed plate to axially reciprocate along the small shaft, and allowing the abrasive belt to abrade the feed plate to form the operating arc segment; and c, releasing the abraded feed plate, and abrading the next feed plate.
Description
Technical field
The present invention relates to a kind of process equipment of rotor spinning machine feed plate, especially, relate to fine finishining mechanism and the processing method of rotor spinning machine feed plate.
Background technology:
As shown in Figure 1, the raw material of rotor spinning machine (sliver 4) is when feeding carding cavity body, the work arc section of feed plate 3 (1a among Fig. 2) is pushed down sliver 4 and is made its surface that is attached to feed roller 2 (periphery of feed roller has the strip helical teeth, with the friction of increase with fiber), drive in the sliver 4 feeding carding cavity bodies by the rotation of feed roller 2 and the acting in conjunction of feed plate, thus the automatic supply of realization raw material (sliver).
The adjustment of raw material supplying amount realizes by the rotating speed of feed roller, makes the cooperation of itself and the count of yarn and complete machine running speed.Owing to the feeding of sliver after the setting of complete machine operating mode must be even, so sliver can not be in the surperficial phenomenon of being obstructed of skidding of feed roller, in order to avoid fiber feeds irregular and affects yarn qualities.As the feed plate that cooperates the raw material feeding, its local size requires very high, and particularly the shape and size of arc section require accurately, and the fineness on surface requires very high, and coefficient of friction requires below 0.1, to guarantee the sliver feeding evenly.
Existing method for fine finishing is as shown in Figure 3: adopt cylindrical grinder that the arc surface of feed plate is carried out grinding (the similar mill of cutting), its arc section realized by the grinding of emery wheel, so the shape of arc section, size rely on the shape and size of the wheel face that is in contact with it to guarantee.And emery wheel continuous loss of meeting in grinding process; grinding wheel shape, size will change; the size and dimension of the feed plate arc section of institute's grinding is along with changing; machining accuracy is difficult to guarantee; in order to realize that machining accuracy needs the number of times of trimming wheel more in process; downtime is many, and especially the existence of grinding texture increases the workload of follow-up polishing process greatly.Therefore, the Product Precision of existing processing method processing is low, and production efficiency is low.
In addition, consistent with the emery wheel rotation direction because of the grinding texture on feed plate arc section surface, the circular motion direction that feeds the carding cavity body with sliver is mutually vertical, the phenomenon of skidding and being obstructed easily, be unfavorable for the sliver fiber movement, thereby cause sliver fiber feeding irregular and affect yarn qualities.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of fine finishining mechanism of rotor spinning machine feed plate, can realize accurate processing, guarantees the accurate to dimension of feed plate, realizes that sliver evenly feeds in the carding cavity body.
A kind of fine finishining mechanism of rotor spinning machine feed plate is characterized in that:
It comprises axis and the macro-axis that is parallel to each other, and described macro-axis is wound with wide abrasive band by Motor Drive between described axis and the macro-axis,
Described axis next door is provided with a little axle in parallel, distance between described little axle axle center and the axis axle center is less than the length of feed plate, the radius of little axle is less than the axis hole radius, and the radius of described axis adds that the thickness sum in abrasive band equals the radius of feed plate work arc section.
The width in described abrasive band is 200mm～300mm.
The present invention also provides a kind of processing method of rotor spinning machine feed plate, it is characterized in that, may further comprise the steps:
A, the shaft hole sleeve of feed plate is contained on the little axle, opens motor;
B, with hand with the other end of feed plate by above the abrasive band that is pressed on the axis, and make feed plate along the axially reciprocating of little axle, polish to feed plate and form the work arc section in the abrasive band;
The feed plate that c, relieving have been polished is polished to next feed plate.
Operation principle of the present invention and the course of work are that the radius of axis adds that the thickness sum in abrasive band equals the standard radius to cotton plate work arc section to be processed, so marks exactly specification through the arc surface of polishing feed plate.
Add man-hour, the driven by motor macro-axis rotates, and makes the abrasive band high-speed motion, and feed plate is through on the little axle, and pressure makes along little axle 6 axially reciprocatings a little.The feed plate arc section is close to the surface, abrasive band, and grinding is carried out to the feed plate circular arc in the abrasive band.Because the abrasive belt circular arc shape is the shape of parcel axis, can not change, and the more former emery wheel in abrasive band is wide a lot of times, when feed plate moved back and forth, Wear Mechanism of Abrasive Belt was even, and wear extent is little, and the deflection that itself produces is very little.Therefore the arc size of feed plate is more easy to control, and the abrasive band life-span is longer, shuts down and changes the abrasive band number of times seldom.The abrasive band direction of motion is the circular motion direction, and the texture of feed plate arc-shaped surface also is circumferencial direction, and is consistent with the sliver fiber feeding direction of motion, is beneficial to fiber movement and breaks away from.
Work in-process, feed plate can be eliminated the inhomogeneous fineness impact on the feed plate arc surface of surface, abrasive band sand grains along little axle axially reciprocating, and follow-up polishing process workload is reduced greatly, have reduced job costs.Measure through practice, the feed plate arc surface of processing has very high fineness, and its coefficient of friction is 0.08.Thereby it is low to have solved existing feed plate machining accuracy, inefficiency, the problem that cost is high.
In a word, the present invention is applicable to process the arc surface of feed plate active section, and dimensional accuracy and profile guarantee that easily the superficial makings of product is consistent with the circular motion direction that fiber breaks away from, and is beneficial to fiber movement.The situation that does not have trimming wheel is shut down number of times and is greatly reduced, and downtime is few, and working (machining) efficiency is improved.Utilize this method processing feed plate, constant product quality, working (machining) efficiency is high, and cost is low.Has higher practical value.
