Abstract

The utility model relates to a bar transient process automatic regulator for a drawing frame, which belongs to the auxiliary equipment of a textile machinery and is used for preventing a bar from deteriorating for a drawing frame. The utility model is characterized in that the utility model is composed of a moveable upper press roller and a fixed lower press roller which are installed on and below a bar in a front roller position of a drawing frame, an inductance transducer which is fixedly installed right above a bearing connecting rod by a shaft sleeve, an SCM (Single Chip Microcomputer) and a soft starter which are in turn installed between the output end and the drawing frame by leads. The utility model has the advantages of simple structure, low cost, motor overload protection, power saving, long service life, small size, light weight, high performance-price ratio, etc., and can be started in a linear mode in various dynamic running states.

Description

The drawing frame bar is done the transient process self-checking device

A kind of drawing frame bar is done the transient process self-checking device, belongs to the auxiliary equipment technical field of textile machine, is mainly used in the motor that drives drawing frame, avoids bar to do and worsens.

In the prior art, famous in the world big textile enterprise all drops into lot of manpower and material resources and is testing the dried problem that worsens of bar when solving drawing frame open and close car at present.But they adopt computer control and converter technique.Like this, not only design is complicated, and the cost extra-high-speed is difficult for promoting, and too low to the utilization rate of frequency converter, causes great waste.

It is a kind of simple in structure that the purpose of this utility model is to provide; economical and practical, can accomplish under various dynamic state of run that linear startup also can take into account production efficiency and evenness quality is chosen the best driving time, economize on electricity; overload protection, the drawing frame bar that cost performance is high is done the transient process self-checking device.

In the drawing frame production process, cause bar to do the mechanism of deterioration and the performance characteristics of soft initiator, at existing questions in the prior art, basic design of the present utility model is: (it is movable to go up pressure roller with being located at the dried a pair of pressure roller up and down of drawing frame front roller place bar, lower compression roller fixedly mounts) and the dried signal that changes of inductance type transducer pick-up slip, after handling amplification, linearity exports to single-chip microcomputer, little Processing Interface that the output analog signal is given soft initiator after its initialize program is handled computing, again through its inter-process and comparison operation, start-up time and the speed motor in order to the driving drawing frame is set, thereby realizes purpose of design.

Drawing frame bar described in the utility model is done the transient process self-checking device, it is characterized in that this device is by being located at the dried following lower compression roller 1 of drawing frame front roller place bar, with top last pressure roller 2, and the connecting rod 4 that is connected with one end bearing 3 and the inductance type transducer 6 that installs by location axle sleeve 5 in 2～3mm eminence directly over its top, be loaded on output and the single-chip microcomputer 7 between the drawing frame 9 and soft initiator 8 formations of this sensor 6 successively by lead.

Above-mentioned lower compression roller 1 is fixedly mounted on the frame, the two ends of last pressure roller 2 then be contained in can be respectively along an elongated slot up and down on two above-mentioned bearings 3 of fine motion.

The utility model has the advantages that: simple in structure; cost is low; owing to adopt soft initiator to drive, can under various dynamic state of run, realize linear startup, and can take into account production efficiency and evenness quality is chosen the best driving time; starting current is little; have overload protection can prolong motor service life, volume is little, and is in light weight; the cost performance height, can fundamentally solve drawing frame from static to causing bar to do the problem that worsens when static at a high speed with by high speed steering.

Accompanying drawing is each parts assembly configuration structure schematic diagram of one of the utility model most preferred embodiment user mode.

In conjunction with the accompanying drawings and most preferred embodiment, further describe architectural feature of the present utility model as follows: do at the bar at drawing frame front roller place and adorn a pair of irony up and down, chromium plating, special, diameter is the pressure roller of 70mm, lower compression roller 1 is installed on the frame, the two ends of last pressure roller 2 then are contained in respectively can be in an elongated slot up and down on the bearing 3 of fine motion, wherein an end bearing 3 connects a cylindrical connecting rod 4, its top insertion is fixed in the end opening of the location axle sleeve 5 directly over it, the two is and is slidingly matched, suitable for reading by spin a Bi15-M30-LIU type inductance type transducer and make its lower edge apart from above-mentioned connecting rod 4 upper end 2.5mm of screw thread at this location axle sleeve 5 installed the single-chip microcomputer 7 of Mcs-51 type and the soft initiator 9 of the built-in little processing of France's product ALHTON type by lead successively between the output of sensor 6 and drawing frame 10.

Change as present embodiment:

1, the material of upper and lower pressure roller and overall dimensions can suitably change, and the vertical interval between small end and the sensor can suitably be adjusted between 2～3mm;

2, the specifications and models of sensor, single-chip microcomputer and soft initiator etc. all can be done equivalence and replace;

3, also can be for the ease of observation directly perceived at the output termination display and/or the printer of single-chip microcomputer.
