As a specific embodiment of the present invention, the vertical wall of the limit groove 17 close to the adjacent low-position guide roller 2 is polished to prevent the vertical plate 12 from rubbing heavily with the groove wall of the limit groove 17 when moving downward due to the restoring force of the torsion spring, and a noise reduction pad is fixedly connected to the groove wall of the sector groove 16, the thickness of the noise reduction pad gradually decreases from the middle to the front side and the rear side, when the vertical plate 12 tilts under the driving action of the torsion spring, the noise reduction pad can buffer the vertical plate 12 to reduce the generation of noise, and the thickness of the noise reduction pad gradually decreases from the middle to the front side and the rear side, so the middle of the noise reduction pad can buffer the vertical plate 12, and the middle of the noise reduction pad can be blocked by a thinner portion when being deformed, thereby prolonging the service life of the noise reduction pad.
As a specific embodiment of the present invention, the top end of the vertical plate 12 is fixedly connected with a first magnetic block 26, the arc-shaped wall of the sector-shaped groove 16 is rotatably connected with a plurality of second magnetic blocks 27, the bottom of each second magnetic block 27 is a positive electrode, and the top of each first magnetic block 26 is a negative electrode; when vertical board 12 deflected to the sector groove 16 in, the magnetic path 26 at its top can receive the attraction of No. two magnetic paths 27 in the sector groove 16, and make vertical board 12 deflect in to the sector groove 16 fast, later when magnetic path 26 reached depression bar 22 department, when vertical board 12 extrudeed depression bar 22 promptly, because No. two magnetic paths 27 rotate and connect, this moment, magnetic path 26 bottom department is the positive pole, can receive the repulsion effect of No. two magnetic paths 27 bottom positive poles, and then can play the impetus to vertical board 12, the pressure power to depression bar 22 is bigger, and then the intensity from driving the gas that post 24 spun is bigger.
As a specific embodiment of the present invention, a cavity is opened inside the vertical plate 12, a gravity block 28 is arranged inside the cavity, and an accelerating spring 29 is fixedly connected to the bottom of the gravity block 28; when the vertical plate 12 deflects to an inclined state from a vertical state, the gravity of the gravity block 28 cannot be completely pressed on the accelerating spring 29 at the moment, and then the accelerating spring 29 can recover a certain length to push the gravity block 28 to move towards the first magnetic block 26, so that the weight at the free end of the vertical plate 12 is larger, and the deflection speed of the vertical plate 12 is higher.
The working principle of the invention is as follows:
referring to the attached drawings 1-6 of the specification, because the non-woven fabric needs to be processed through a plurality of processes before entering the forming equipment, the non-woven fabric needs to be guided to different positions by a guiding device, when the guiding is carried out, because all guiding rollers are in a fixed state, after the production is finished, the non-woven fabric is cut, the end part of the non-woven fabric is in a loose state, the fixing is needed independently, extra steps are added, and when the next production is carried out, the end part of the non-woven fabric needs to be manually pulled, so that the end part of the non-woven fabric enters the forming machine, because the non-woven fabric is rubbed with a plurality of guiding rollers, the difficulty in pulling is high, the invention mainly solves the problem that how to rapidly fix the non-woven fabric after the production is finished, before the production, the end part of the non-woven fabric; the concrete measures and the using process are as follows; after production is finished, the end part of the non-woven fabric is cut off, then the hydraulic rod 7 is controlled to contract, the hydraulic rod 7 sequentially drives the T-shaped disc 8, the connecting plate 10 and the vertical plate 12 to move downwards so as to drive the high-position guide roller 3 to move downwards, when the top end of the vertical plate reaches the top part of the fan-shaped groove 16, the motor 6 is started, the motor 6 drives the fixing rod 9 to rotate, the wound connecting rope 14 is gradually loosened, finally, the top end of the vertical plate 12 is driven to deflect towards the low-position guide roller 2 under the action of a torsional spring, the high-position guide roller 3 is tightly pressed on the adjacent low-position guide roller 2, the non-woven fabric can be fixed, the non-woven fabric is prevented from loosening, when the end part of the non-woven fabric needs to be pulled and sent into a forming machine, the motor 6 can be started, the motor 6 drives the hydraulic rod 7 to rotate, the hydraulic rod 7 drives the fixing rod 9 at the, connect rope 14 to drive connecting rod 13, connecting rod 13 deflects out from sector groove 16 with the vertical board 12 of slope again, make vertical board 12 be in vertical state again, and then high-order guide roll 3 breaks away from low level guide roll 2, the non-woven fabrics is no longer fixed, and because high-order guide roll 3 is less than original height, when pulling non-woven fabrics tip removes, the pulling that can be more convenient, thereby can make the non-woven fabrics tip enter into the make-up machine, the degree of difficulty when having reduced the pulling, install the inside back of make-up machine when with the non-woven fabrics, can start hydraulic stem 7 extension this moment, it rises to original position to drive high-order guide roll 3.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
