[0037] The operation steps of the utility model are as follows:

[0038] ​​​1. Artificially through hoisting equipment in the loading position, the fiber cord material roll and the mat roll are loaded to one of the guide opening positions 2-1 of the double-position guide opening device 2, and the mat after unwinding is wound on the mat roll, and the unwound cord is fixed to the joint swing arm. The guide opening position 2-1 loaded with the material roll and the mat roll is rotated to the working position by button control, and the unwound fiber cord 7 is pulled to the guillotine cutter type cutting main machine 1 according to the required material pulling path, and the first feeding work is completed, and the equipment can enter the normal working state, the fiber cord material roll is unwound, and it is transported to the guillotine cutter type cutting main machine 1.

[0039] 2. Artificially through hoisting equipment in the loading position, the empty fiber cord material roll and the mat roll are unloaded from the guide opening position 2-1, and then the fiber cord material roll and the mat roll are loaded to the guide opening position 2-1, and the mat after unwinding on the material roll is wound on the mat roll, and the unwound cord is fixed to the joint swing arm.

[0040] 3. After the fiber cord 7 is pulled to the guillotine cutter type cutting main machine 1 position, the cloth lifting mechanism of the guillotine cutter type cutting main machine 1 lifts the fiber cord 7 away from the cutter surface, the cord clamp mechanism 4-1 is driven by the X, Y axis linkage mechanism 4 to extend into the guillotine cutter type cutting main machine 1 and clamp the fiber cord 7, and at the same time, the multiple lifting material receiving frames 5-2 of the cord sheet material supply device 5 are synchronously lifted to prepare for material receiving.

[0041] 4. After the cord clamp mechanism 4-1 clamps the fiber cord 7, the fiber cord 7 is pulled out from the guillotine cutter type cutting main machine 1 according to the angle and length required by the process under the drive of the X, Y axis linkage mechanism 4, and in the process of pulling the material, the floating roller of the double-position guide opening device 2 can freely lift to eliminate the speed difference between the cord pulling roller and the X, Y axis linkage mechanism 4.

[0042] 5. After the fiber cord 7 is pulled out to the position, the cloth lifting mechanism and the cloth pressing mechanism of the guillotine cutter type cutting main machine 1 fall down at the same time to press the fiber cord 7, and the cord clamp mechanism 4-1 releases the fiber cord 7 and retreats a safe distance.

[0043] 6. After the cord clamp mechanism 4-1 releases the fiber cord 7, the fiber cord 7 falls onto the lifting material receiving frame 5-2 under the action of gravity, and the vacuum suction assembly of the lifting material receiving frame 5-2 starts to work, so that the fiber cord 7 can be stably attached to the lifting material receiving frame 5-2.

[0044] 7. The crankshaft transmission mechanism of the guillotine cutter type cutting main machine 1 works to drive the cross beam and the upper cutter to move downward and work together with the lower cutter to cut the continuous fiber cord 7 into single fiber cord sheets 7-1, and after the cutting work is completed, the crankshaft transmission mechanism continues to work to drive the cross beam and the upper cutter to move upward to the highest point.

[0045] 8. After the fiber curtain sheet 7-1 is cut, multiple lifting receiving frames 5-2 adsorb the fiber curtain sheet 7-1 and descend synchronously to place the fiber curtain sheet 7-1 onto multiple conveyor belts 5-1. Then, the adsorption function of the lifting receiving frame 5-2 stops, and the multiple lifting receiving frames 5-2 continue to descend synchronously to the lowest point.

[0046] 9. After the fiber curtain sheet 7-1 falls onto the multiple conveyor belts 5-1, the multiple conveyor belts 5-1 activate the adsorption function and drive the fiber curtain sheet 7-1 to move to the right.

[0047] 10. Upon initial startup, the fiber fabric sheet 7-1 cut out for the first time must be placed manually onto the conveyor belt 6-4 of the fabric unloading device 6, and the tail of the fiber fabric sheet 7-1 must be aligned with the lower baffle 3-3 of the impact plate type connector device 3.

[0048] 11. The equipment automatically and continuously repeats steps 3, 4, 5, 6, 7, 8, and 9, and can continuously feed the cut fiber curtain sheet 7-1 to the right.

[0049] 12. During the conveying process of the fiber curtain sheet 7-1, the upper baffle 3-4 of the impact-plate joint device 3 is lowered in advance. The fiber curtain sheet 7-1 is precisely positioned after photoelectric detection during conveying, ensuring that the head of the fiber curtain sheet 7-1 is aligned with the upper baffle 3-4. The distance between the upper baffle 3-4 and the lower baffle 3-3 allows the two fiber curtain sheets 7-1 to overlap end-to-end according to their upper and lower positions. Figure 7 As shown.

[0050] 13. When the end of the fiber curtain sheet 7-1 is aligned with the upper baffle 3-4, the overlapping pressure plate 3-5 of the impact-plate type joint device 3 moves downward to compact the joint. During the pressing process, the overlapping pressure plate 3-5 will press against the lower baffle 3-3 and move downward, such as... Figure 8 As shown; after the joint is compacted, the overlapping pressure plate 3-5 moves upward back to the high point position. During the rising process of the overlapping pressure plate 3-5, the lower baffle 3-3 automatically rises to the high point so that the material tail can reliably follow the lower baffle 3-3 when it is unloaded.

[0051] 14. After the overlapping pressure plate 3-5 returns to its high point, conveyor belt 6-4 and multiple conveyor belts 5-1 start simultaneously. Conveyor belt 6-4 transports the overlapped fiber curtain belt 7-2 to the right as a whole. Figure 9 As shown, at the same time, the material tail retraction mechanism 6-1 of the fabric unloading device 6 retracts to the left to prepare for the next joint.

[0052] 15、When the end of the fiber cord 7-2 passes the detection switch at the lower baffle 3-3, the multiple conveyors 5-1 stop running, the conveyor 6-4 continues running to send the end of the fiber cord 7-2 away from the area of the lower baffle 3-3 by a certain distance, the cord clamping mechanism 6-3 clamps the fiber cord 7-2, then the conveyor 6-4 retreats by a certain distance, so that the fiber cord 7-2 forms a storage ring between the conveyor 6-4 and the cord clamping mechanism 6-3.

[0053] 16、After the conveyor 6-4 completes the retreat, the end retreat mechanism 6-1 retreats to align the end of the fiber cord 7-2 to the edge of the lower baffle 3-3, then the upper baffle 3-4 descends and presses the end of the fiber cord 7-2 on the lap joint support plate 3-2, and the cord clamping mechanism 6-3 releases the fiber cord 7-2, as shown in Fig. 16. Figure 10

[0054] 17、The equipment automatically and continuously repeats the steps 12, 13, 14, 15 and 16, so that the cut fiber cord 7-1 can be continuously spliced and compacted.

[0055] 18、When the joint has a misalignment phenomenon, the misalignment adjusting mechanism 6-2 can be rotated to eliminate or improve the misalignment phenomenon.

[0056] 19、During the operation of the equipment, if the cutting angle needs to be changed, the angle adjusting mechanism 2-2 of the double-station guide opening device 2 can be used to adjust the angle (within ±5°) between the double-station guide opening device 2 and the guillotine cutter 1, and the lap joint angle adjusting mechanism 3-1 can be used to adjust the angle between the impact plate type joint device 3 and the multiple conveyors 5-1, and the X-Y axis linkage mechanism 4 can automatically simulate the angle to pull the material according to the set angle.

[0057] 20、When the fiber cord 7 in the work station reel is used up, the equipment automatically positions the end of the material to a suitable position, the work station rotating mechanism drives the guide opening work station 2-1 to switch positions, the empty work station and the full work station are exchanged, the large reel joint mechanism automatically splices the first end and the tail end of the new and old material reels together, and continues to convey the fiber cord 7 to the guillotine cutter 1; after the first end and the tail end of the new and old material reels are spliced, the joint swing arm swings back to the transfer position, and the operator repeats the work content of the second step to replace the reel at the guide opening work station 2-1 and complete the related work.

[0058] Thus, the utility model completes a period of work, and after the first material is pulled by the operator, the operator does not need to operate or intervene in the case of normal operation of the equipment, and the operator only needs to replace the material reel and the cloth reel at the guide opening device according to the requirements.​
