DETAILED DESCRIPTION

[0024] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] A cutting device for a film rewinding machine, such as Figure 1-5As shown, it includes a placing table 1, a motor 2 arranged on the placing table 1, and a connecting seat 3 fixedly connected to the output shaft of the motor 2, a fixing rod 4 is clamped on the connecting seat 3, and a plurality of circular knives 5 are fixedly connected to the fixing rod 4. The fixing rod 4 can be directly removed from the connecting seat 3 for replacement, so that the circular knife 5 can be adjusted conveniently when films of different widths need to be cut, a supporting rod 6 is fixedly connected to the placing table 1, and a plurality of placing frames 7 are slidably connected to the supporting rod 6, a through slot 8 is provided on the placing frame 7, and a plurality of sliding rods 9 are slidably connected to both sides of the placing frame 7, and the sliding rods 9 arranged on both sides of the same placing frame 7 are staggered, and a grinding block 10 that fits the circular knife 5 is fixedly connected to the end of the sliding rod 9 close to the circular knife 5, so as to facilitate grinding work, and a contraction spring 11 is fixedly connected to the end of the sliding rod 9 away from the circular knife 5 so that the grinding The grinding block 10 always fits the circular knife 5, and the contraction spring 11 is fixedly connected to the placement frame 7 near one end of the circular knife 5. When grinding is needed, the motor 2 can be turned on to rotate the circular knife 5. At this time, the grinding block 10 fits the circular knife 5 because of the contraction spring 11, so the circular knife 5 can be ground during the rotation of the circular knife 5. The placement frame 7 is fixedly connected with a plurality of nozzles 12, and the placement table 1 is provided with a water supply component 13 for supplying water to the nozzles 12. During the grinding process, water is supplied to the nozzles 12 through the water supply component 13 to keep the grinding block 10 moist and prevent the grinding block 10 from wearing out quickly. In this way, the circular knife 5 can be ground when the equipment is performing slitting work, and there is no need to stop the rewinding work in order to grind or replace the circular knife 5, and the cutting knife can be kept sharp, thereby improving the overall quality of the film.

[0026] like Figure 1 , Figure 2 , Figure 6 As shown, the water supply component 13 includes a water tank 1301 fixedly connected to the placement table 1, a water pump 1302 fixedly connected to the placement table 1, and a water outlet pipe 1303 fixedly connected to the output end of the water pump 1302. The input end of the water pump 1302 is connected to the water tank 1301, and the water outlet pipe 1303 is fixedly connected and conducted to the nozzle 12. The water outlet pipe 1303 runs through the placement table 1. Liquid is first injected into the water tank 1301, and then the water is pumped into the water outlet pipe 1303 through the water pump 1302, and finally enters the nozzle 12, thereby completing the water supply work.

[0027] like Figure 1 , Figure 3 , Figure 4 As shown, a sponge block 16 that fits the circular knife 5 is detachably connected to the side of the placement frame 7 away from the support rod 6, which can remove water stains and impurities that may exist on the circular knife 5 to avoid affecting the cutting.

[0028] like Figure 1 , Figure 2 , Figure 4 , Figure 6As shown, a filter plate 14 is clamped on the water tank 1301, which can filter the liquid flowing out of the through groove 8. The bottom end of the water tank 1301 is fixedly connected with an inclined platform 15, which can guarantee the water supply demand to the maximum extent after the liquid is lost.

[0029] like Figure 1-2 As shown, a stabilizing frame 17 is fixedly connected to the water outlet pipe 1303 , which can reinforce the water outlet pipe 1303 and extend the service life of the water outlet pipe 1303 .

[0030] like Figure 1 , Figure 6 As shown, guide plates 18 are fixedly connected to both sides of the water tank 1301 to prevent the liquid from splashing out of the water tank 1301 after contacting the filter plate 14 .

[0031] like Figure 1-2 As shown, the portion of the water outlet pipe 1303 inside the placement table 1 is spirally arranged, so that the water outlet pipe 1303 has a longer stroke and can move with the nozzle 12 at the same time.

[0032] like Figure 1-4 As shown, a baffle 19 is fixedly connected to the side of the placement frame 7 away from the sponge block 16 to prevent liquid from splashing out of the placement frame 7 and wetting the film during spraying.

[0033] Working principle: When grinding is needed, first inject liquid into the water tank 1301, and at the same time, the motor 2 and the water pump 1302 can be turned on. After the motor 2 is turned on, the circular knife 5 will rotate. At this time, the grinding block 10 fits with the circular knife 5 due to the contraction spring 11. Therefore, the circular knife 5 can be ground during its rotation. At the same time, the water pump 1302 pumps the liquid into the water outlet pipe 1303. After the liquid enters the nozzle 12, the nozzle 12 sprays the circular knife 5. At this time, the circular knife 5 rotates so that the liquid contacts the grinding block 10, so that the grinding block 10 remains moist, and then the liquid after grinding The liquid flows down from the through groove 8 and drips onto the filter plate 14. The filtered liquid will re-enter the water tank 1301. When the position of the circular knife 5 needs to be adjusted, due to the setting of the spiral part of the water outlet pipe 1303, the placement frame 7 can be adjusted directly following the circular knife 5. In this way, the circular knife 5 can be polished when the equipment is performing the slitting work, and the liquid used during polishing can be reused. It can also be adjusted along with the circular knife 5. There is no need to stop the rewinding work in order to polish or replace the circular knife 5, and the cutter can be kept sharp, thereby improving the overall quality of the film.

[0034] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
