Description

Technical Field

[0001] The utility model relates to the technical field of winding machines, in particular to a cooling device for a disc knife of a winding machine. Background Art

[0002] In the production process of aluminum foil, a whole sheet of aluminum foil is usually cut into aluminum foil strips of different widths by a coiling machine. During the cutting process, the high-speed rotation of the coiling machine's disc knife generates high temperatures. The high temperature of the disc knife not only causes the tool material to soften, increases the wear rate, and shortens the tool life, but may also cause the material to deform or melt, thereby affecting the cutting accuracy and quality. Therefore, the disc knife needs to be cooled in time during the cutting process. Existing cooling methods mostly use the spraying of coolant and cooling gas. However, in actual use, there are still the following shortcomings:

[0003] 1. Most existing cooling devices are set up independently from the winder. During the cooling process, the staff needs to manually adjust the position of the nozzle. This is not only very inconvenient to operate, but also cannot ensure that the coolant or cooling gas can be evenly sprayed on the surface of the disc cutter, affecting the cooling effect.

[0004] 2. When the disc cutter is sprayed with coolant, the disc cutter is in a high-speed rotating state, and the coolant sprayed onto the surface of the disc cutter will splash outward due to its centrifugal force, which not only pollutes the surrounding environment, but also has an adverse effect on the cooling of the disc cutter;

[0005] 3. Although the cooling gas blowing method can achieve cooling, the efficiency of the gas cooling method is low during the long-term high-speed rotation of the disc cutter, and the cooling effect is not ideal;

[0006] Therefore, a kind of coiling machine disc knife cooling device that can overcome above-mentioned disadvantages is badly needed. Utility Model Content

[0007] In order to overcome the shortcomings of the background technology, the utility model discloses a cooling device for a disc knife of a winding machine. The utility model cooperates with a coolant spraying mechanism and a cooling gas spraying mechanism. While spraying coolant toward the disc knife for cooling, the evaporation of the coolant can be accelerated by blowing cooling gas, which not only greatly improves the cooling efficiency of the disc knife, but also effectively reduces the splashing of coolant on the disc knife.

[0008] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0009] A cooling device for a coiling machine disc cutter comprises a rotating rod rotatably mounted between two mounting seats, and a disc cutter mounted on the rotating rod and rotating with the rotating rod. The rotating rods on both sides of the disc cutter are provided with bearings coaxially arranged with the rotating rods, the inner diameter of the inner ring of the bearing is adapted to the rotating rod, the bearing is fixedly connected to the adjacent mounting seats by a connecting rod, one end of the connecting rod is fixedly connected to the outer ring end face of the bearing, and the other end is fixedly connected to the mounting seat, and the outer ring surface of the outer ring of the bearing is respectively provided with a coolant spraying mechanism for spraying coolant onto the disc cutter, and a cooling gas spraying mechanism for spraying cooling gas onto the disc cutter.

[0010] Furthermore, the coolant spraying mechanism includes a coolant nozzle, a coolant delivery pipe and a coolant delivery device. The coolant nozzle is fixedly mounted on the outer ring surface of the outer ring of the bearing, and the coolant nozzle is connected to the coolant delivery device through the coolant delivery pipe.

[0011] Furthermore, the cooling gas spraying mechanism includes a gas nozzle, a gas delivery pipe and a gas delivery device. The gas nozzle is fixedly mounted on the outer ring surface of the outer ring of the bearing, and the gas nozzle is connected to the coolant delivery device through the gas delivery pipe.

[0012] Furthermore, the coolant nozzle and the gas nozzle are both fan nozzles or atomizing nozzles.

[0013] Furthermore, both the coolant nozzle and the gas nozzle are provided with a conical cover, the small diameter end of the cover is connected to the coolant nozzle and the gas nozzle, and the large diameter end of the cover is arranged toward the disc cutter.

[0014] Furthermore, the connecting rod is a pneumatic or electric telescopic rod.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: by using the coolant spraying mechanism in conjunction with the cooling gas spraying mechanism, the coolant can be sprayed on the surface of the disc cutter to cool it, and the cooling gas spraying can be used to accelerate the evaporation of the coolant, thereby greatly improving the cooling effect of the disc cutter;

[0016] The setting of the bearing enables the coolant nozzle and the gas nozzle to correspond accurately and stably to the side of the disc cutter, providing strong support for the subsequent uniform coolant spraying and cooling gas blowing on the disc cutter;

[0017] By using fan-shaped or atomizing nozzles, the coolant and cooling gas can be evenly sprayed onto the surface of the disc cutter;

[0018] By setting up a cover, the spraying of the coolant can be blocked to avoid the coolant spraying and causing pollution;

[0019] By setting a retractable and adjustable connecting rod, the distance between the coolant spraying mechanism and the cooling gas spraying mechanism and the disc cutter can be adjusted, thereby providing strong support for the subsequent cooling of the disc cutter;

[0020] The utility model cooperates with the coolant spraying mechanism and the cooling gas spraying mechanism to spray the coolant toward the disc cutter for cooling, and at the same time accelerates the evaporation of the coolant by blowing the cooling gas, which not only greatly improves the cooling efficiency of the disc cutter, but also effectively reduces the splashing of the coolant on the disc cutter.

[0024] The technical solution of the present invention will be described below in conjunction with the drawings in the embodiments of the present invention. In the description, it should be understood that if there are terms such as "upper", "lower", "front", "back", "left", and "right" indicating directions or positional relationships, they only correspond to the drawings of the present invention and are for the convenience of describing the present invention, and do not indicate or imply that the device or component referred to must have a specific direction.

[0025] Please refer to the instruction manual Figs. 1-2 , the utility model provides a technical solution:

[0026] Embodiment 1, a cooling device for a circular knife of a winding machine, comprising a rotating rod 4 rotatably mounted between two mounting seats 3, and a circular knife 1 mounted on the rotating rod 4 and rotating with the rotating rod 4, and rotating rods 4 on both sides of the circular knife 1. The rod body is provided with a bearing 5 coaxially arranged with the rotating rod 4, and the inner diameter of the inner ring 12 of the bearing 5 is adapted to the rotating rod 4. The bearing 5 is fixedly connected to the adjacent mounting seats 3 through a connecting rod 6, one end of the connecting rod 6 is fixedly connected to the end face of the outer ring 12 of the bearing 5, and the other end is fixedly connected to the mounting seat 3, and the outer ring 11 of the bearing 5 is respectively provided with a coolant for spraying a coolant to the circular knife 1. The spraying mechanism 2 and the cooling gas spraying mechanism 7 for spraying cooling gas to the disc cutter 1 are specifically comprised of a coolant spraying head 10, a coolant delivery pipe 8, and a coolant delivery device. The coolant spraying head 10 is fixedly mounted on the outer ring surface of the outer ring 11 of the bearing 5. The coolant spraying head 10 is connected to the coolant delivery device through the coolant delivery pipe 8. The cooling gas spraying mechanism 7 comprises a gas spraying head 13, a gas delivery pipe 14, and a gas delivery device. The gas spraying head 13 is fixedly mounted on the outer ring surface of the outer ring 11 of the bearing 5. The gas spraying head 13 is connected to the coolant delivery device through the gas delivery pipe 14.

[0027] During the operation of the winding machine, the inner ring 12 of the bearing 5 rotates with the rotating rod 4, and the outer ring 12 of the bearing 5 is kept stationary by the limit of the connecting rod 6. When the disc cutter 1 is cooled, the coolant nozzle 10 sprays coolant toward the disc cutter 1, and the gas nozzle 13 blows cooling gas toward the disc cutter 1. As the disc cutter 1 rotates, the cooling gas sprayed by the gas nozzle 13 can blow the coolant on the surface of the disc cutter 1, thereby accelerating the evaporation of the coolant, which not only effectively improves the cooling effect of the disc cutter 1, but also reduces the splashing of the coolant.

[0028] Example 2: In order to ensure that the coolant and cooling gas can be evenly sprayed onto the surface of the disc cutter 1, the coolant nozzle 10 and the gas nozzle 13 are both fan-shaped nozzles or atomizing nozzles. In order to prevent the coolant from being sprayed onto the outside of the disc cutter 1, the coolant nozzle 10 and the gas nozzle 13 are both provided with a cover body 9 with a conical structure. The small diameter end of the cover body 9 is connected to the coolant nozzle 10 and the gas nozzle 13, and the large diameter end of the cover body 9 is arranged toward the disc cutter 1.

[0029] Embodiment 3: In order to ensure that the coolant and cooling gas can be accurately sprayed onto the surface of the disc cutter 1, the connecting rod 6 is a pneumatic or electric telescopic rod. Since the inner ring 12 of the bearing 5 is adapted to the rotating rod 4, the connecting rod 6 can be used to push and adjust the distance between the bearing 5 and the disc cutter 1, so that the coolant nozzle 10 and the gas nozzle 13 can accurately spray the coolant and cooling gas toward the surface of the disc cutter 1.
