Description
Technical Field
The invention relates to the technical field of curtain cloth separation and transmission, in particular to an angle-adjustable multi-row conveyor belt.
Background
In actual use, the large-cylinder curtain cloth needs to be cut into small-section curtain cloth with different angles, so that the large-cylinder curtain cloth is convenient to wind and produce. The conventional horizontal cutting equipment has the common problem that the large-tube curtain cloth is laid on the conveyor belt after being unfolded, and the curtain cloth is in a tensioning state, so that the curtain cloth cannot deflect when being cut, but the two ends of the small-segment curtain cloth obtained by cutting have the problem of big and small ends, namely the width of the two ends of the curtain cloth is inconsistent. The problem of the large head and the small head occurs because the tension applied to the curtain cloth by horizontal cutting is unbalanced when the curtain cloth is wider, so that the two ends of the cut small-section curtain cloth shrink differently. This problem is inherent in such older bed cutting apparatus and is difficult to improve, and therefore a curtain cutter with higher cutting accuracy is required.
The curtain cloth cutting machine adopts a set of linear modules controlled by a servo motor to cut curtain cloth directionally, and the cutting knife can cut the curtain cloth in a feeding way at any angle only by controlling the running speeds of the linear modules in the X-axis direction and the Y-axis direction respectively. Meanwhile, the curtain cloth does not need to be tensioned when the equipment is used for cutting, and a set of vacuumizing device is arranged below the conveying belt, so that the curtain cloth can be tightly adsorbed, and is paved on the conveying belt, and the curtain cloth is not shifted and deflected when being cut.
However, the cut small-section curtain cloth is tensioned next to one another and cannot be automatically separated in transmission, which affects the work of subsequent equipment for automatically splicing the cut small-section curtain cloth. The follow-up equipment is required to accurately identify the outline of the small-section curtain cloth, so that the small-section curtain cloth needs to be completely separated and kept flat, and in order to ensure that the curtain cloth cutting and splicing automation is smoothly carried out, a machine capable of separating the next small-section curtain cloth needs to be provided.

As shown in fig. 2 and 3, the movable roller set 3, the floating roller set 4 and the corner positioning rod mechanism cooperate to enable the dividing line to deviate, the conveying speed of the left conveying belt mechanism 1 is V2, the conveying speed of the right conveying belt mechanism 2 is V1, and V2 is greater than V1, and the conveying speed of the curtain fabric cutting machine is V1, so that small-section curtain fabrics can enter the right conveying belt mechanism 2 by the curtain fabric cutting machine without deviation, when the small-section curtain fabrics enter the left conveying belt mechanism 1 through the right conveying belt mechanism 2, the small-section curtain fabrics can be automatically separated due to the speed difference, the separation distance can be adjusted through the speed difference, and the deviation angle of the dividing line is consistent with the curtain fabric cutting angle, so that the small-section curtain fabrics are prevented from being deviated after being separated.
As shown in fig. 2-7, floating roller groups 4 are arranged below the left conveyor belt mechanism 1 and the right conveyor belt mechanism 2 of each of the other narrow conveyor belt mechanisms except the fifth narrow conveyor belt mechanism; except for the fifth row of narrow conveying belt mechanisms, each row of narrow conveying belt mechanisms is provided with a movable roller group 3, and the movable roller groups 3 are connected with the conveying belts 5 of the left conveying belt mechanism 1 and the right conveying belt mechanism 2; the corner positioning rod mechanism is connected with the movable roller group 3.
Except for the fifth row of narrow conveying belt mechanisms, each row of narrow conveying belt mechanisms is further provided with a movable long groove 6, two ends of the movable roller group 3 are respectively connected with the left conveying belt mechanism 1 and the right conveying belt mechanism 2 through a conveying belt 5 and are arranged on the movable long groove 6 in a sliding manner, and when the curtain fabric cutting machine is in operation, the movable roller group 3 is arranged in an inclined straight line, and the inclined straight line offset angle is consistent with the curtain fabric cutting angle. The movable roller group 3 comprises a first roller 31, a second roller 32, a deep groove ball bearing 33 and a corner positioning rod 34, wherein the first roller 31 and the second roller 32 drive the conveyor belts 5 on the left conveyor belt mechanism 1 and the right conveyor belt mechanism 2 to rotate, the deep groove ball bearing 33 is slidably arranged on the movable long groove 6, and the center of the corner positioning rod 34 is fixed below the fifth row of narrow conveyor belt mechanisms and is axially connected with the movable roller group 3 of each other row of narrow conveyor belt mechanisms.
The corner positioning rod mechanism comprises a corner positioning rod 34, a motor and reduction gearbox 35, a screw rod 36 and a ball screw rod linear bearing 37, wherein the motor and reduction gearbox 35 is connected with the screw rod 36, the screw rod 36 is connected with the ball screw rod linear bearing 37, and the ball screw rod linear bearing 37 is connected with the corner positioning rod 34. The motor and the motor of the reduction gearbox 35 contain an encoder.
The motor and the reduction box 35 drive the screw rod 36 to rotate, the ball screw linear bearing 37 can move left and right, the corner positioning rod 34 connected with the ball screw linear bearing 37 can start rotating by taking the 5 th row narrow conveying belt mechanism as the center, and the movable roller group 3 of the other 8 rows narrow conveying belt mechanisms is driven to move left and right. Therefore, the rotation angle of the corner positioning rod 34 can be conveniently controlled within the moving range of the movable roller group 3 so as to adapt to the angle of the small-section curtain cloth with any specification, and manual adjustment is not required to be performed by disassembling equipment.
A proximity switch 7 is arranged in the middle of one side of the ninth narrow conveying belt mechanism, and the proximity switch 7 is a zero point of rotation of the corner positioning rod 34. The rotation angle of the corner positioning rod 34 is 0 and the sharp angle of the small curtain is 90 degrees when the corner positioning rod 34 is used. According to the needs, the motor is electrically connected with the PLC, the angles corresponding to the small-section curtain cloth are set in the PLC in advance, then the rotation number of the motor is controlled through the encoder, the rotation angle positioning rod 34 starts from the zero point and rotates to the corresponding position, and the movable roller group 3 also moves to the corresponding position under the action of the rotation angle positioning rod 34. The motor and screw 36 are rotated to the encoder set number of turns, the motor is stopped, the motor is locked by the braking action, and the corner positioning rod 34 is stopped and firmly fixed in the position.

When the cord specifications are to be changed and the angle is to be adjusted, the tensioning force applied to the conveyor belt 5 by the cylinder must be removed in order to enable the middle movable roller group 3 to translate left/right. The electromagnetic valve 91 is electrified, the passage of the air source into the air cylinder 9 is cut off by the electromagnetic valve 91, and the air in the upper chamber of the air cylinder 9 is discharged from the opening A of the electromagnetic valve 91B, and at the moment, the conveyor belt 5 only tightens the belt by the dead weight of the floating roller set 3, so that the conveyor belt 5 is prevented from excessively preventing the left/right movement of the movable roller set 3, and the condition that the conveyor belt 5 is loosened and separated from the rollers due to the fact that the conveyor belt 5 is completely not stressed is avoided, and the conveyor belt 5 is in a proper tightening state in the whole adjustment process. After the movable roller group 3 moves to the set position and the angle is adjusted in place, the electromagnetic valve 91 is powered off again, and the air cylinder 9 is actuated again to fully tighten the conveyor belt 5.
