[0025] The non-woven tape is a kind of tape formed by arranging continuous fibers parallel to each other, without adding weft yarns, and bonded with adhesives. It is a strip-shaped insulating lashing material with a certain width, impregnated with high-temperature heat-curing unsaturated polyester resin using treated unidirectional continuous twisted non-alkali glass fiber yarns. The lashing tape has good flexibility and adhesiveness, unfolds into a mesh structure, is easy to unwind, does not shed filaments, and has no overlapping marks. This product has excellent properties such as high strength, impact resistance, high modulus, low elongation, no hysteresis, and no eddy current loss. It is mainly used for the lashing and fastening of transformer cores and coils. It is also used as the winding and lashing material for motors, traction motors, generators, lightning arresters, instrument transformers, DC motors, electric welders, and high-pressure vessels.
[0026] During the production process of the non-woven tape, it needs to be wound onto a reel and then cut after the winding is completed. In the existing production process of the non-woven tape, the cutting method is usually to manually cut the end with a cutting tool. Therefore, someone needs to stay at the production station for a long time, which is quite labor-consuming and the production cost is relatively high.
[0027] See Figure 1 , this application provides a non-woven tape cutting device, which includes a bottom plate 1, a mounting plate 2, a lifting mechanism 3, and a cutting mechanism 4. The mounting plate 2 is arranged below the bottom plate 1. The lifting mechanism 3 includes a lifting rod 30 and a driving cylinder. The driving cylinder is fixed on the mounting plate 2, and the lifting rod 30 is connected to the power output end of the driving cylinder. A pressing block 5 is installed at the end of the lifting rod 30, and the pressing block 5 is located above the bottom plate 1. The cutting mechanism 4 includes a driving motor 40 and a cutting blade 41. The driving motor 40 is fixed on the bottom plate 1, and the cutting blade 41 is connected to the power output end of the driving motor 40.
[0028] During the working process, the produced non-woven tape passes through the lifting mechanism 3 and the cutting mechanism 4 and then winds around the reel. When it is necessary to cut the non-woven tape, the driving cylinder controls the lifting rod 30 to descend, and the lifting rod 30 drives the pressing block 5 to press tightly against the bottom plate 1, thereby pressing the non-woven tape tightly. Then the driving motor 40 drives the cutting blade 41 to descend to cut the non-woven tape. This device does not require workers to manually cut the non-woven tape with tools, saving labor and reducing costs.
[0029] In addition, this application also includes a control mechanism. The control mechanism is connected to the driving motor 40, the driving cylinder, and the reel for winding the non-woven tape in a controlled manner. After the reel stops winding, the control system will first control the driving cylinder to work, causing the lifting rod 30 to descend, pressing the non-woven tape tightly through the pressing block 5, and then control the driving motor 40 to work, cutting the non-woven tape through the cutting blade 41.
[0030] In some embodiments, the cutting mechanism 4 further includes a fixing plate 42. The fixing plate 100 is vertically fixed on the bottom plate 1, and the driving motor 40 is installed on the fixing plate 100.
[0031] In some embodiments, a support roller 6 is provided on one side of the bottom plate 1 close to the cutting structure.
[0032] Specifically, the support roller 6 is installed on the front side of the bottom plate 1 through a mounting seat 60. The non-woven tape bypasses the support roller 6 and is connected to the reel, preventing the non-woven tape from being pressed on the front side of the bottom plate 1 and being worn for a long time.
[0033] In some embodiments, a guiding groove 7 is provided on the bottom plate 1 to ensure that the non-woven tape in the previous process can quickly and accurately enter the lifting mechanism 3. The guiding groove 7 is used to guide the non-woven tape to the lifting mechanism 3.
[0034] Specifically, two vertical plates are provided on the upper surface of the bottom plate 1. The two vertical plates are arranged in parallel at intervals. The distance between the two vertical plates is greater than the width of the non-woven tape. One end of the two vertical plates is bent into a flared structure, and the other end of the two vertical plates extends to the lifting mechanism 3. The non-woven tape from the previous process can smoothly enter the lifting mechanism 3 and the cutting mechanism 4 through the guiding groove 7 without manual traction.
[0035] In some embodiments, there are two lifting rods 30. Two through holes are provided on the bottom plate 1, and the two lifting rods 30 are respectively inserted into the two through holes. The pressing block 5 is connected to the tops of the two lifting rods 30.
[0036] Specifically, two through holes are provided on the bottom plate 1. The two lifting rods 30 are cylindrical rods. The two lifting rods 30 pass through the through holes. The tops of the two lifting rods 30 are located above the bottom plate 1. The bottoms of the two lifting rods 30 are connected to the driving cylinder. During the working process, the driving cylinder drives the two lifting rods 30 to lift and lower, and the two lifting rods 30 will drive the pressing block 5 to lift and lower, thereby realizing the pressing action.
[0037] In some embodiments, a connecting rod 50 is fixed on the pressing block 5, and both ends of the connecting rod 50 are connected to the two lifting rods 30.
[0038] In some embodiments, the connecting rod 50 is connected to the lifting rod 30 through a lifting sleeve 500, and the lifting sleeve 500 is detachably connected to the lifting rod 30.
[0039] When the height of the pressing block 5 needs to be adjusted, loosen the lifting sleeve 500 from the lifting rod 30, and then adjust the lifting sleeve 500 along the lifting rod 30. After the height of the pressing block 5 is adjusted in place, fix the lifting sleeve 500 to the lifting rod 30.
[0040] In some embodiments, a plurality of first pin holes are provided on the lifting rod 30, and the first pin holes are arranged at intervals along the length direction of the lifting rod 30. A second pin hole is provided on the lifting sleeve 500, and a pin is inserted through the first pin hole and the second pin hole.
[0041] When it is necessary to adjust the height of the pressing block 5, slide the lifting sleeve 500 so that the first pin hole of the lifting sleeve 500 is aligned with the corresponding second pin hole on the lifting rod 30 at the corresponding height, and then insert the pin into the first pin hole and the second pin hole for positioning.
[0042] In some embodiments, a lifting guide groove 20 is provided on the mounting plate 2. The two lifting rods 30 are both connected through a connecting rod 31. A slider is provided on the connecting rod 31, and the slider is assembled in the lifting guide groove 20 and connected to the power output end of the driving cylinder. During the working process, the driving cylinder drives the slider to lift and slide in the lifting guide groove 20, and the slider will drive the two lifting rods 30 to lift and lower stably.
[0043] In some embodiments, a cutting groove 101 is provided on the bottom plate 1 at a position corresponding to the cutting edge 41. When the cutting edge 41 drops, it will press on the cutting groove 101 to cut off the non-woven tape.
