The dual-station curtain fabric guiding and automatic splicing equipment includes a photoelectric switch system, a first guiding device 10 and a second guiding device 11 connected in sequence, and a conveyor belt device 7 located below the first and second guiding devices 10 and 11. The conveyor belt device 7 is equipped with a first pressure roller 6 and a second pressure roller 12. The first and second guiding devices 10 and 11 are symmetrically distributed. Figure 1In the diagram, the first guide opening device 10 is on the left, and the second guide opening device 11 is on the right. The pusher roller 5 inside the first guide opening device 10 is close to the pusher roller 5 inside the second guide opening device 11. The first pressure roller 6 is located within the area of ​​the first guide opening device 10, and the second pressure roller 12 is located within the area of ​​the second guide opening device 11. Both the first pressure roller 6 and the second pressure roller 12 are closer to the end of the equipment operation relative to the nearest curtain 9. In the diagram, both the first pressure roller 6 and the second pressure roller 12 are on the left side of the hanging curtain 9.

[0024] The conveyor belt device 7 is equipped with a first motor and a reducer 71; a first three-axis cylinder 61 is provided below both the first pressing roller 6 and the second pressing roller 12.

[0025] like Figure 1 , Figure 3 and Figure 4 As shown, both the first guide device 10 and the second guide device 11 are equipped with a large fabric roller 1, a padding roller 2, a rubber-coated power roller 3, a clamping roller 4, and a pusher roller 5. The rubber-coated power roller 3 and the clamping roller 4 are mounted on the same fixed plate. The clamping roller 4 is fixed to the fixed plate by a swing arm 41, on which a cylinder 42 is mounted. The large fabric roller 1 is located on one side of the clamping roller 4, and a third motor and a reducer 11 are mounted on the large fabric roller 1. The padding roller 2 is located on the other side of the large fabric roller 1, and a fourth motor and a reducer 21 are mounted on the padding roller 2. The rubber-coated power roller 3 is located below the clamping roller 4 on the other side, and a second motor and a reducer 31 are mounted on the rubber-coated power roller 3. The pusher roller 5 is suspended below the rubber-coated power roller 3, and a second three-axis cylinder 51 is mounted on one side of the pusher roller 5.

[0026] The photoelectric switch system includes several pairs of photoelectric switches and their reflectors, which are respectively set on the conveyor belt device 7, the first guiding device 10 and the second guiding device 11 along the path of the curtain 9. Each pair of photoelectric switches and their reflectors are set on an axis, and the guiding curtain 9 will pass through the middle of the photoelectric switches and their reflectors during the guiding and conveying process.

[0027] The first guiding device 10 is equipped with four sets of photoelectric switches and their reflectors. A first photoelectric switch 81 is set above the fabric clamping roller 4, a second photoelectric switch 82 is set below the fabric pushing roller 5, and a third photoelectric switch 83 and a fourth photoelectric switch 84 are set sequentially on the side of the fabric pressing roller 6 near the curtain pretreatment device.

[0028] The second guiding device 11 is equipped with three sets of photoelectric switches and their reflectors. The fifth photoelectric switch 85, the sixth photoelectric switch 86 and the seventh photoelectric switch 87 are arranged vertically downwards and are higher than the conveyor belt device 7. The fifth photoelectric switch 85 is located above the clamping roller 4, and the sixth photoelectric switch 86 and the seventh photoelectric switch 87 are located on one side of the pressing roller 6.

[0029] The device is also connected to a PLC system for intelligent control of its operation.

[0030] The specific operating principle of the device of this invention is as follows: The first opening device 10 and the second opening device 11 alternately open the curtain fabric. Initially, the first opening device 10 starts working first. After the first opening device 10 finishes its work, the curtain fabric on the two devices is spliced ​​together by the conveyor belt device 7, and then the second opening device 11 continues to work. At the same time, the operator replaces the large curtain fabric tube 1 and the padding fabric tube 2 of the first opening device 10. After the second opening device 11 finishes its work, the curtain fabric on the two devices is spliced ​​together by the device, and then the first opening device 10 continues to work again. At the same time, the operator replaces the large curtain fabric tube 1 and the padding fabric tube 2 of the second opening device 11, and so on, repeating the cycle. The specific details are as follows.

[0031] 1) Operation of the first guiding device 10: The curtain fabric 9 on the first guiding device 10 is passed through the curtain fabric "expansion, tension, and punching" equipment and the curtain fabric cutting equipment for cutting. After the first guiding device 10 is started, the large curtain fabric tube 1 is driven by the third motor and the reducer 11, and the padding fabric tube 2 is driven by the fourth motor and the reducer 21. When the curtain fabric 9 is guided open, the motor of the large curtain fabric tube 1 rotates clockwise, and at the same time the motor of the padding fabric tube 2 rotates counterclockwise. At this time, the curtain fabric 9 is driven to the left by the curtain fabric "expansion, tension, and punching" equipment. The conveyor belt device 7 does not operate, and the first three-axis cylinder 61 below the first pressure roller 6 and the second pressure roller 12 are both in the raised state, that is, the first pressure roller 6 and the second pressure roller 12 are both in the suspended state. During the process of the first opening device 10 opening the curtain 9, the first photoelectric switch 81 is always blocked by the opened curtain 9. As the curtain 9 is fully opened, the last section of the curtain 9 will detach from the large curtain tube 1 and hang on the clamping roller 4. At this time, the light emitted by the first photoelectric switch 81 will be connected to the corresponding reflector. The PLC receives the signal, the shaft of the second three-axis cylinder 51 extends, and the pusher roller 5 pushes the curtain 9 hanging on the clamping roller 4. The curtain 9 changes its hanging state so that it will not pile up when it finally falls to the conveyor belt below.

[0032] 2) Automatic Fabric Splicing Stage (Second Opening Device 11): The fabric 9 of the large fabric tube 1 of the first opening device 10 is fully opened and falls onto the lower conveyor belt. However, the fabric "expansion, tensioning, and punching" equipment continues to operate normally, driving the fabric 9 to continue moving to the left until the tail of the fabric passes the third photoelectric switch 83. At this time, the light emitted by the third photoelectric switch 83 connects with the corresponding reflector, the PLC receives the signal, the second three-axis cylinder 51 in the first opening device 10 begins to retract, and the first motor and reducer 71 begin to rotate, driving the conveyor belt carrying the fabric 9 to move towards the second opening device 11, that is, the conveyor belt device 7 moves to the right. At the same time, the fabric "expansion, tensioning, and punching" equipment, in coordination with the conveyor belt device 7, conveys the fabric 9 clockwise.

[0033] The conveyor belt device 7 operates continuously until the curtain 9 blocks the seventh photoelectric switch 87 on the second opening device 11, as... Figure 4 As shown, when the PLC receives the signal, the conveyor belt device 7 stops rotating, and the process of opening the large curtain tube and automatically splicing the curtain in the second opening device 11 begins. Inside the second opening device 11, the shaft of the cylinder 42 extends, and the clamping roller 4 and the rubber-coated power roller 3 clamp the curtain 9 opened by the large curtain tube 1 in the middle. Then, the second motor and reducer 31 start to rotate clockwise, while the motor of the large curtain tube 1 rotates counterclockwise, and the motor of the padding roller 2 rotates clockwise, and the curtain 9 begins to open and descend vertically.

[0034] During the descent of the curtain 9, the head of the curtain 9 blocks the sixth photoelectric switch 86. The PLC receives a signal, and the first three-axis cylinder 61 of the second pressure roller 12 retracts, meaning the second pressure roller 12 lands on the conveyor belt. The conveyor belt then begins to move to the left, causing the first guide device 10 of the curtain 9 on the conveyor belt to move in the same direction. At the same time, the curtain 9 guided from the large curtain tube 1 continues to descend continuously, eventually landing on the conveyor belt and overlapping with the curtain 9 already on the conveyor belt. Then, as the conveyor belt carries the curtain 9 to the left, the second pressure roller 12 completely and tightly presses the ends of the two overlapping curtains together, completing the automatic splicing of the curtain.

[0035] 3) Operation of the second guide opening device 11: The device PLC is set with a delay program. After the preset time is reached, the automatic splicing of the curtain fabric is completed. At this time, the PLC controls the shaft of the cylinder 42 in the second guide opening device 11 to retract, and lifts the clamping roller 4. The second motor and reducer 31 stop rotating. At the same time, the shaft of the first three-axis cylinder 61 extends, and the second pressure roller 12 is lifted. After that, the entire horizontal curtain fabric cutting machine enters the normal curtain fabric cutting operation.

[0036] After the second opening device 11 has fully opened the curtain 9, the last section of the curtain 9 is detached from the large curtain tube 1 and hangs on the clamping roller 4. At this time, the light emitted by the fifth photoelectric switch 85 is connected to the corresponding reflector. The PLC receives the signal, the shaft of the second three-axis cylinder 51 extends, and the pusher roller 5 extends to push the curtain 9 to an inclined position to prevent the curtain 9 from falling vertically and piling up on the conveyor belt. This facilitates the subsequent automatic splicing of the curtain. At the same time, the first motor and reducer 71 start to work. The motor starts to rotate counterclockwise, and the conveyor belt moves to the left. In conjunction with the rotating drive roller on the horizontal cutting "curtain" expansion, tensioning, and punching equipment, the curtain 9 is moved to the left.

[0037] 4) Automatic fabric splicing stage (first guiding device 10): When the fabric on the conveyor belt moves within the range of the first guiding device 10 but does not pass the pressure roller 6 or the second photoelectric switch 82, if... Figure 3 As shown, the second photoelectric switch 82 is connected to the corresponding reflector. When the PLC receives the signal, the shaft of the second triaxial cylinder 51 in the second opening device 11 retracts, and the first opening device 10 starts to operate.

[0038] Inside the first guiding device 10, the shaft of cylinder 42 extends, causing the clamping roller 4 and the rubber-coated power roller 3 to clamp the fabric 9. Simultaneously, the second motor and reducer 31 rotate, and the guided fabric 9 begins to descend vertically. At the same time, the shaft of the first three-axis cylinder 61 of the first pressing roller 6 retracts, causing the first pressing roller 6 to descend and press onto the conveyor belt. The head of the guided fabric 9 descends and overlaps with the tail of the fabric already on the conveyor belt, moving to the left along with the rotation of the conveyor belt. After passing the first pressing roller 6, the overlapping portion of the two fabrics is compacted, completing the automatic fabric splicing stage. Next, through the delay program in the device's PLC, after a preset time, the shaft of cylinder 42 retracts, lifting the clamping roller 4. Simultaneously, the second motor and reducer 31 stop, and the shaft of the first three-axis cylinder 61 extends, lifting the pressing roller 6. Then, the first motor and reducer 71 stop. At this point, the curtain opening has been switched from the second opening device 11 to the first opening device 10. The subsequent opening of the curtain 9 is driven by the "curtain expansion, tensioning, and punching device" and "curtain cutting equipment" of the horizontal cutting machine.
