A kind of single-side machine of mule carriage device synchronously that has accurately
Technical field
The present invention relates to the single-side machine field on the single-face corrugation machine production line, be specifically related to a kind of single-side machine of mule carriage device synchronously that has accurately.
Background technology
At present, on the single-face corrugation machine production line, when single-side machine flowed to dryer with paper, can the paper feeding speed of single-side machine and the paper feeding speed of dryer synchronous, determined by the synchronous mule carriage device of single-side machine.The synchronous mule carriage success or not of single-side machine is seen exactly to the control of long-pending paper state, paper position on the overline bridge, detects accuracy and has arrived which kind of degree.Long-pending paper state, the paper position of tradition overline bridge is to rely on the optoelectronic switch oblique fire that certain altitude is installed on the crossbeam of overline bridge both sides to judge that the single watt of cardboard that single-side machine is produced requires quite high.If single watt of cardboard generation warpage, the testing result of mistake can produce error message, seriously can cause whole production line to break single watt of paper because of dryer and shut down.The fifth wheel of traditional synchronous mule carriage device is installed in sending slowly above the belt of single-side machine, and fifth wheel is pressed on the paper, and it is accurately not high that this synchronous mule carriage device is controlled synchronous mule carriage, and error is bigger.
Summary of the invention
Purpose of the present invention is exactly the deficiency at the synchronous mule carriage function of existing single-side machine, and provides a kind of single-side machine synchronous mule carriage device.
The present invention includes frame, feed rollers, slowly send belt, slowly send belt to be installed on the frame, it also has encoder, the low speed fifth wheel, high speed fifth wheel and length generator, encoder is installed on the roll shaft of single-side machine feed rollers, low speed fifth wheel and high speed fifth wheel are installed on the frame by erection support respectively, and the wheel shaft of the wheel shaft of low speed fifth wheel and high speed fifth wheel is positioned at the below of sending belt slowly, when normal operating conditions, cardboard wadding head is all the time in the swing of high speed fifth wheel, the low speed fifth wheel is positioned at cardboard wadding segment length generator all the time and is installed on the frame, is positioned at the front end that send belt slowly.
Advantage of the present invention is: adorn fifth wheel is counter, be contained in the below of sending belt slowly, letterweight can test the speed fifth wheel on fifth wheel more accurately, and is simple and compact for structure, good reliability, cost is low, and the precision height is influenced not quite by single watt of cardboard, the running that cooperates the whole production line that can effectively guarantee to coordinate with length generator, and installation, maintenance are convenient.
Description of drawings
Accompanying drawing 1 is structural representation of the present invention.
The specific embodiment
As shown in Figure 1, the present invention includes frame 1, feed rollers 2, slowly send belt 3, slowly send belt 3 to be installed on the frame 1, it also has encoder 4, low speed fifth wheel 5, high speed fifth wheel 6 and length generator 7, the fifth wheel of encoder 4 is installed on the roll shaft of single-side machine feed rollers 2, low speed fifth wheel 5 and high speed fifth wheel 6 are installed on the frame 1 by erection support respectively, and the wheel shaft of the wheel shaft of low speed fifth wheel 5 and high speed fifth wheel 6 is positioned at the below of sending belt 4 slowly, when normal operating conditions, cardboard wadding head 8 is all the time in the swing of high speed fifth wheel 6, low speed fifth wheel 5 is positioned at cardboard wadding section all the time, length generator 7 is installed on the frame 1, is positioned at the front end that send belt 4 slowly.
Using method: during use, encoder 4, low speed fifth wheel 5, high speed fifth wheel 6 and length generator 7 are electrically connected with single-chip microcomputer (PLC), single-chip microcomputer electrically connects by the drive motors of executing agency and single-side machine feed rollers.
Working method: during single-side machine work, by manually the paper that comes out in the single-side machine being placed on the paper feed place of belt elevator, by belt elevator cardboard is delivered on the feed belt then earlier.When cardboard moves on feed belt, the moving runner that cardboard drives low speed fifth wheel 6, high speed fifth wheel 7 and encoder 4 rotates together, feed rollers 2 drives encoder 4 and rotates, encoder 4, low speed fifth wheel 5, high speed fifth wheel 6 and length generator 7 are given single-chip microcomputer with the cardboard transporting velocity transfer of data of measuring, single-chip microcomputer is by the rotating speed of the drive motors of actuating mechanism controls single-side machine feed rollers, thereby control reaches the paper feed speed of accurate control single-side machine.When the wadding section of cardboard is moved between high speed fifth wheel 6 and length generator 7, show that single-side machine paper feeding speed is higher than dryer 10 and draws the chart speed degree, at this moment, A length generator 4, low speed fifth wheel 5, high speed fifth wheel 6 and B length generator 7 are given single-chip microcomputer with the cardboard transporting velocity transfer of data of measuring, single-chip microcomputer begins to calculate the deviation of the velocity deviation of single-side machine and dryer and canonical product paper amount and actual long-pending paper amount, when two deviation sums during greater than setting range; Single-chip microcomputer slows down the drive motors of single-side machine feed rollers by executing agency, stop during to the deceleration halt slowing down, be adjusted to normal operating conditions, cardboard wadding head 8 is all the time in the swing of high speed fifth wheel 6, low speed fifth wheel 5 is positioned at cardboard wadding section all the time, and beginning is running at the uniform velocity.When the planar section 9 of cardboard moves on low speed fifth wheel 5, show that single-side machine paper feeding speed is lower than dryer 10 and draws the chart speed degree, A length generator 4, low speed fifth wheel 5, high speed fifth wheel 6 and length generator 7 are given single-chip microcomputer with the cardboard transporting velocity transfer of data of measuring at this moment, and single-chip microcomputer quickens the drive motors of single-side machine feed rollers by executing agency.Cardboard wadding head 8 refers to when the speed of single-side machine is higher than the speed of dryer, and cardboard is piled up sending on the belt slowly, causes that cardboard is wrinkling, and the wrinkling point of cardboard is cardboard wadding head.
