Detailed Description
The present invention will be further explained with reference to the drawings and examples.
Example 1
As shown in figure 1, the splicing paper adjusting and positioning device without stopping comprises a bracket and a traction roller 1, the splicing unit 2, the two unwinding rollers 3 and the servo motor, the two unwinding rollers 3 are horizontally arranged and divided into a left unwinding roller 31 and a right unwinding roller 32, the traction roller 1 and the left unwinding roller 3 are driven by the servo motor to rotate, the splicing unit 2 is positioned right above the centers of the two unwinding rollers, a cursor probe 4 is arranged above the splicing unit 2 and is right opposite to printing paper, signals of the cursor probe 4 are fed back to a servo motor controller of the left unwinding roller, two limiting rollers 5 are horizontally arranged above the cursor probe 4, a floating roller 6 is arranged right below the two limiting rollers 5, a sliding groove 7 is formed in one side, where the floating roller 6 is fixed to a rack, the floating roller 6 is in contact with the sliding groove 7, and is in a side-standing T shape, so that the floating roller 7 can be clamped in the sliding groove, and the floating roller 7 can freely slide up and down; the traction roller 1 is positioned on the left side of the limiting roller 5, and a clamping wheel 8 is arranged below the traction roller.
As shown in fig. 2, the splicing unit 2 is mainly composed of a cylinder 21, a splicing wheel 22 and a fixed wheel 23 from left to right in sequence, one end of the cylinder 21 is fixed on the support, the other end of the cylinder is provided with the splicing wheel 22, the circumferential surfaces of the splicing wheel 22 and the fixed wheel 23 are mutually matched, a rotating shaft of the splicing wheel 22 is obliquely provided with a supporting arm 24, the top of the supporting arm 24 is provided with a cutter 25, and the cutting edge of the cutter 25 faces the fixed wheel 23.
As shown in fig. 3 (the cylinder device of the card wheel is not marked in the figure), the circumference of one side of the fixed wheel 23 close to the splicing wheel 22 in the splicing unit 2 is provided with an air hole 26, and the fixed wheel 23 is hollow and provided with an air exhaust fan 27; a groove 28 is arranged on the end face of one side of the fixed wheel 23, a clamping wheel 29 driven by an air cylinder is arranged on the fixed support, and an air cylinder controller of the clamping wheel is connected to the control unit. The air exhaust fan that sets up on the tight pulley like this outwards bleeds, and the gas pocket outwards admits air, just forms the negative pressure on one side of gas pocket like this, utilizes the air to adsorb the stock form that needs connect and draw on the tight pulley, avoids adopting the adhesive bonding to cause secondary pollution on the tight pulley. Just so utilize the card wheel to block the recess when needs concatenation, carry out the fly-cutting when the cutter and end, the cylinder of card wheel obtains feedback instruction, and the shrink card wheel leaves the recess, and the tight pulley just can begin the circumferential motion along with the pull of stock form like this, avoids the stock form after the concatenation, and rigid pulls the problem emergence that leads to tearing apart like this.
During the concatenation, paste the adhesive tape to the 9 joint departments of new stock form on the roll-off roll of right side earlier, the air exhaust fan on the tight pulley begins work, is stained with adhesive property one side to the adhesive tape and moves towards the splice wheel, and adhesive tape and 9 joint departments of stock form just adhere to on the tight pulley, push down through air pressure and can not fall down and stabilize. The left unwinding roller stops unwinding the old roll paper 10 under the control of the servo motor, the traction roller also stops running and brakes, if the cursor on the paper unwound from the old roll paper 10 exceeds the cursor detecting head, the servo motor of the left unwinding roller starts reverse paper collection, the floating roller floats upwards to provide paper compensation to avoid the paper from being torn off, and when the paper cursor allows the cursor detecting head, the servo motor of the left unwinding roller stops running through a feedback signal. Then the air cylinder in the splicing unit starts to work, the splicing wheel and the cutter move towards the direction of the fixed wheel, the old paper is attached to the adhesive tape at the joint of the new paper, and the cutter synchronously and accurately positions and cuts off the old paper, so that the new paper and the old paper are spliced together. The whole operation is synchronously and quickly finished, and the time is short. And finally, the traction roller is normally started to insert the new roll paper 9 into the printing system, and the splicing unit does not influence the normal roll paper transmission after being reset.
Example 2
The specific implementation manner is different from the embodiment 1 in that: the left unwinding roller 31 and the right unwinding roller 32 are located in the same sliding groove, the base penetrates through the other end of the sliding groove and is fixed through a bolt, and the gears are arranged at one end, located on the back face of the sliding groove, of the left unwinding roller 31 and the right unwinding roller 32. Two unreel the spool and can freely alternate the position about like this, servo motor is located the spout left side, can drive to be located the left unreel the roller and rotate. Meanwhile, the whole new roll paper and the old roll paper can be well spliced only by arranging the fixed wheel and the splicing wheel, the two wheels are not required to move, and the actual use cost of the whole equipment is reduced.
The whole roll changing work does not need to stop printing work, so that the printing efficiency is improved, and the waste of printing materials is avoided. Meanwhile, the splicing paper or the traction roller part is effectively subjected to paper compensation through the up-and-down floating of the floating roller, so that the old paper roll can be spliced with the new paper roll more tightly, and seamless splicing is realized.
