The specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt the conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0035] The following is combined with Figure 1-4 , further details of this application are given.

[0036] The present application provides a slitting machine with a quantitative supply device for slitting liquid, which adopts the following technical solution:

[0037] Reference Figure 1 and Figure 2The slitting machine includes a frame 1, a liquid box 3, a peristaltic pump 4 and a sprayer 5. The frame 1 is a carrier of the slitting machine. A slitting knife 11 is fixedly installed on the frame 1. The blade of the slitting knife 11 is circular. The slitting knife 11 is driven to rotate by a servo motor. Spray heads 2 are installed on both sides of the slitting knife 11. The spray heads 2 face the side of the slitting knife 11. In this embodiment, a total of 4 spray heads 2 are installed on both sides of the slitting knife 11. A spray head 2 is installed at the top and bottom of each side. Each spray head 2 faces the side of the slitting knife 11 for spraying slitting liquid, forming a protective film on the side of the slitting knife 11, reducing the wear of the slitting knife 11, and increasing the service life of the slitting knife 11. The liquid box 3 is fixedly installed on the frame 1. The slitting liquid is stored in the liquid box 3. The slitting liquid can be a lubricating liquid, a cleaning liquid, a cooling liquid, etc., which provide a maintenance effect on the slitting knife 11. The peristaltic pump 4 is mounted on the frame 1. The peristaltic pump 4 pumps the fluid by alternately squeezing and releasing the hose by its pump body. One end of the peristaltic pump 4 is fixedly connected to a liquid inlet pipe 41, and the other end is fixedly connected to a liquid supply pipe 42. The liquid inlet pipe 41 is connected to the liquid box 3. The slitting liquid in the liquid box 3 enters the peristaltic pump 4 through the liquid inlet pipe 41, and then enters the liquid supply pipe 42 from the peristaltic pump 4. The sprayer 5 is mounted on the frame 1. The sprayer 5 includes a plurality of atomization channels. In each atomization channel, the liquid and compressed air can be mixed to form a mist fluid. One end of the sprayer 5 is connected to the liquid supply pipe 42 of the peristaltic pump 4, and compressed air is injected through an air compressor to atomize the slitting liquid. Then, under the push of the compressed air, the slitting liquid mist fluid is transported to the nozzle 2 through the spray pipe 51 and sprayed on the side of the slitting liquid. Compared with the nozzle 2 spraying the slitting liquid directly on the side of the slitting knife 11, the slitting liquid that is evenly controlled by the peristaltic pump 4 and then atomized and sprayed has a smaller droplet diameter and a larger spraying range, making the slitting liquid attached to both sides of the slitting knife 11 more uniform.

[0038] Further, refer to Figure 1 , the slitting machine also includes a manifold 6. The manifold 6 is installed on the sprayer 5. An air inlet (not shown in the figure) and several air outlets are provided on the manifold 6. The air inlet is connected to the air compressor. Each air outlet is opened and closed by a solenoid valve. Each air outlet is fixedly connected to a gas pipeline 61. When in use, according to the number of spray pipelines 51 of the sprayer 5, an equal number of gas pipelines 61 are connected to the corresponding connection position of the sprayer 5. When the air compressor inputs compressed air into the manifold 6, the manifold 6 evenly distributes the compressed air to several gas pipelines 61, so that each atomization channel of the sprayer 5 is injected with compressed air in the same state, so that the atomization efficiency of different channels of the atomizer is the same. When the atomization channel in the sprayer 5 needs to be repaired, the air outlet on the manifold 6 is closed by the solenoid valve, and the atomization channel that needs to be repaired can be correspondingly closed, thereby reducing the time for disassembly and improving convenience.

[0039] In the preferred embodiment of the present application, refer to Figure 1 and Figure 2 A protective cover plate 12 is installed around the slitting knife 11, and the nozzle 2 is installed on the inner wall of the protective cover plate 12. A liquid storage part 13 is embedded on the protective cover plate 12. The liquid storage part 13 uses a flexible material with water absorption properties, which can be wool felt or a water-absorbing sponge. In this embodiment, wool felt is used. The nozzle 2 is connected to the liquid storage part 13, and can spray the slitting liquid into the liquid storage part 13. The side of the liquid storage part 13 abuts against the side of the slitting knife 11. During the contact and extrusion process between the liquid storage part 13 and the slitting knife 11, the slitting liquid in the liquid storage part 13 penetrates and is smeared on the side of the slitting knife 11. As the slitting knife 11 rotates, it is evenly smeared on the side of the slitting knife 11, so that the slitting liquid is sprayed more evenly.

[0040] Further, refer to Figure 2 and Figure 4 A contact pad 14 is bonded to one side of the protective cover 12 close to the slitting knife 11. The contact pad 14 is made of absorbent fiber material. In this embodiment, a dust-free cloth woven with polyester fibers is selected. The contact pad 14 has good water absorption and cleaning efficiency, and can prevent fibers from falling off during friction, so that the slitting liquid can be continuously and evenly penetrated into the slitting knife 11.

[0041] In the preferred embodiment of the present application, refer to Figure 3 A liquid regulating valve 7 is installed on the sprayer 5. The liquid regulating valve 7 can adjust the flow rate of the cutting liquid entering the sprayer 5, control the amount of the cutting liquid combined with the compressed air in the sprayer 5, and thus control the atomization amount of the sprayer 5.

[0042] In the preferred embodiment of the present application, refer to Figure 3 The sprayer 5 is provided with a gas regulating valve 8. The gas regulating valve 8 can adjust the flow rate of the compressed air entering the sprayer 5, control the flow rate of the compressed air combined with the cutting liquid in the sprayer 5, and thus control the atomization rate of the sprayer 5 and the delivery rate in the spray pipe 51.

[0043] In the preferred embodiment of the present application, refer to Figure 1 , a control panel 9 is installed on the peristaltic pump 4, and the control panel 9 includes a touch screen and a microcomputer chip. The touch screen is for users to input control instructions, and the microcomputer chip can control the circuit on and off of the peristaltic pump 4. A time relay (not shown in the figure) is installed on the peristaltic pump 4, and the time relay signal is connected to the control panel 9. By setting the time relay through the control panel 9, the working time of the peristaltic pump 4 can be set, so as to realize the timed delivery of the slitting liquid to the slitting knife 11 and improve the work efficiency. In addition, under the working state of the atomization efficiency of the sprayer 5 being stable, quantitative supply can also be generated through timed delivery, thereby saving resources and improving resource utilization.

[0044] Furthermore, a flow meter (not shown in the figure) is installed on the liquid box 3, and the flow meter signal is connected to the control panel 9. The flow meter monitors the changes in the cutting liquid in the liquid box 3. The flow meter can accurately control the supply of the cutting liquid, making the quantitative replenishment more accurate, thereby improving resource utilization.

[0045] The experimental principle of the embodiment of the present application is as follows: when it is necessary to spray slitting liquid on the slitting machine, the slitting liquid in the liquid box 3 enters the peristaltic pump 4 through the liquid inlet pipe 41, and is then evenly pumped into the liquid supply pipe 42 through the peristaltic pump 4 and connected to the atomizer. The compressed air is dispersed into the air supply pipe 61 through the manifold 6 and connected to the atomizer; the slitting liquid and the compressed air are combined and atomized, and then enter the spray pipe 51 under the push of the compressed air, and are transported to the nozzle 2 on the protective cover 12. The liquid storage part 13 absorbs the slitting liquid spray in the nozzle 2, and then contacts the side of the slitting knife 11 through the contact pad 14, and is evenly penetrated and smeared on the side of the slitting knife 11, thereby improving the uniformity of the slitting liquid spraying.

[0046] According to the disclosure and teaching of the above description, the technicians in the field of the utility model can also change and modify the above implementation. Therefore, the utility model is not limited to the above specific implementation, and any obvious improvement, replacement or modification made by the technicians in this field on the basis of the utility model belongs to the protection scope of the utility model.
