Description

Technical Field

[0001] The invention relates to the technical field of aluminum foil winding devices, and in particular to a ceramic insulating aluminum foil transfer rewinding machine. Background Art

[0002] The production process of ceramic insulating aluminum foil will inevitably produce products that need to be rewound and rejected due to base paper, aluminum foil roll-changing joints and related quality defects, and the number accounts for a certain proportion. The traditional rewinding method is to install limit rings at both ends of the paper guide roller in the rear part of the rewinding machine. During the rewinding process, the paper edge will not exceed the limit ring, thereby ensuring the flatness of the paper reel. In order to solve the problem that the paper edge of the ceramic insulating aluminum foil will inevitably rub against the two sides of the limit ring of the rewinding paper guide roller, the existing two ends of the paper guide roller are limited by guide wheels or other rotatable parts (such as a winding device for a ceramic insulating aluminum foil transfer film composite machine with patent announcement number CN220467053U), which reduces friction to a certain extent. However, for some ceramic insulating aluminum foils with thin thickness, excessive limiting at both ends can easily cause the edge of the ceramic insulating aluminum foil to wear and become scrapped. Summary of the invention

[0003] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a ceramic insulating aluminum foil transfer rewinding machine, thereby solving the problem in the prior art that the ceramic insulating aluminum foil is scrapped due to large edge wear caused by large offset.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] A ceramic insulating aluminum foil transfer rewinding machine comprises a frame, a reeling roller is arranged at one end of the frame, a reeling roller is arranged at the other end of the frame, a guide roller is rotatably connected to the middle of the frame, a floating ring is arranged at each end of the guide roller, and a blowing device is arranged outside the two floating rings;

[0006] The blowing device comprises a cylindrical cover, which is fixedly connected to the rotating shaft of the guide roller, a rotating groove is arranged on the outer side of the cylindrical cover, the rotating groove is rotatably connected to the annular cover, a vent hole is arranged at the bottom of the rotating groove, one side of the frame is fixedly connected to the air delivery pipe, the air delivery pipe and the annular cover are fixedly connected to a branch pipe, and a flow sensor is arranged on the branch pipe;

[0007] A plurality of air leakage holes are arranged in an annular array outside the cylindrical cover, and the floating ring slides on the inner wall of the cylindrical cover to cover the air leakage holes.

[0008] Preferably, the floating ring is made of sponge material or porous prefabricated foam.

[0009] Preferably, the outer circle of the guide roller is provided with an interlayer cavity, the inner side of the end face of the guide roller is provided with an air path, the outer side of the end face of the guide roller is provided with an air blowing hole, the inner wall of the air path is fixedly connected with a cover sheet of elastic material, the cover sheet covers the air blowing hole, and one side of the cover sheet can be pushed open by the air flow, the rotating shaft of the guide roller is a hollow structure and is connected with the air blowing hole, and an input hole is provided on the outer side of the rotating shaft;

[0010] The outer circle of the guide roller is provided with a plurality of inclined holes, and the inclined holes are communicated with the interlayer cavity and the air path.

[0011] Preferably, the distance between one end of the inclined hole located on the outer surface of the guide roller and the corresponding blowing device is greater than the distance between the inner end of the inclined hole and the corresponding blowing device.

[0012] Preferably, the outer circle of the guide roller is provided with an arc-shaped groove which is continuous with the outer circle of the guide roller.

[0013] Preferably, at least two arc-shaped grooves are provided.

[0014] Preferably, the inclined hole is located in the arc-shaped groove.

[0015] The advantages of the present invention are as follows: a ceramic insulating aluminum foil transfer rewinding machine provided by the present invention applies a flexible blowing force to the two floating rings that limit the ceramic insulating aluminum foil through the cylindrical covers at both ends, and can play a flexible role in limiting when the ceramic insulating aluminum foil is conveyed and deviated (the airflow support force can be adjusted according to the offset of the floating ring to avoid rigid limiting causing damage to the edge of the ceramic insulating aluminum foil). When the movement of the floating ring exceeds the limit, that is, the floating ring blocks the air vent, the airflow entering the cylindrical cover will not be discharged from the air vent but will be fully used to return the floating ring to the top, so that necessary measures are taken to correct the offset of the ceramic insulating aluminum foil, taking into account flexible limiting and offset adjustment, thereby ensuring the conveying quality of the ceramic insulating aluminum foil during the rewinding process.

[0016] The present invention blocks the air leakage holes on one hand, so that the airflow exerts thrust on the floating ring to prevent the ceramic insulating aluminum foil from further deflecting. On the other hand, part of the airflow pushes open the cover sheet and is blown out from the inclined hole after the air path and the interlayer cavity, exerting an axial thrust in the air cavity formed on the bottom surface of the ceramic insulating aluminum foil, thereby pulling the ceramic insulating aluminum foil back and avoiding the edge of the ceramic insulating aluminum foil from continuously rubbing against the floating ring. The floating ring is not solely relied on to push the ceramic insulating aluminum foil back, thereby avoiding damage to the edge of the ceramic insulating aluminum foil.

[0021] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0022] Example

[0023] like Figures 1 to 4 As shown, a ceramic insulating aluminum foil transfer rewinding machine provided by the present invention comprises a frame 1, a reeling roller 11 is arranged at one end of the frame 1, a reeling roller 12 is arranged at the other end of the frame 1, a guide roller 2 is rotatably connected to the middle of the frame 1, a floating ring 3 is arranged at each end of the guide roller 2, and a blowing device 4 is arranged on the outer side of the two floating rings 3;

[0024] The blowing device 4 includes a cylindrical cover 41, which is fixedly connected to the rotating shaft of the guide roller 2. A rotating groove 42 is arranged on the outer side of the cylindrical cover 41, and the rotating groove 42 is rotatably connected to the annular cover 43. The annular cover 43 is fixed and air is supplied to the cylindrical cover 41 during its rotation. A vent hole 44 is arranged at the bottom of the rotating groove 42. An air supply pipe 45 is fixedly connected to one side of the frame 1. The air supply pipe 45 and the annular cover 43 are fixedly connected to a branch pipe 46. A flow sensor 47 is arranged on the branch pipe 46. The flow sensor 47 belongs to a detection element of the prior art and is used to detect changes in air flow in the pipeline, and feed back the monitoring results to the control system to adjust the size of the input air flow.

[0025] A plurality of air leakage holes 48 are arranged in an annular array outside the cylindrical cover 41. The floating ring 3 slides on the inner wall of the cylindrical cover 41 to cover the air leakage holes 48. The floating ring 3 is made of sponge material or porous prefabricated foam. The air flow can partially penetrate the floating ring 3 to cool the friction heat at the edge of the ceramic insulating aluminum foil.

[0026] The present invention applies a flexible blowing force to the two floating rings 3 for limiting the ceramic insulating aluminum foil through the cylindrical covers 41 at both ends, which can play a flexible role in limiting when the ceramic insulating aluminum foil is deviated during transmission (the airflow supporting force can be adjusted according to the offset of the floating ring 3 to avoid damage to the edge of the ceramic insulating aluminum foil caused by rigid limiting). When the movement of the floating ring 3 exceeds the limit, that is, the floating ring 3 blocks the air leakage hole 48, the airflow entering the cylindrical cover 41 will not be discharged from the air leakage hole 48 but will be completely used for returning the floating ring 3 to the top, so that necessary measures are taken to correct the offset of the ceramic insulating aluminum foil, taking into account both flexible limiting and offset adjustment, thereby ensuring the transportation quality of the ceramic insulating aluminum foil during the rewinding process.

[0027] As an embodiment of the present invention, an interlayer cavity 21 is arranged on the outer circle of the guide roller 2, an air path 22 is arranged inside the end face of the guide roller 2, an air blowing hole 23 is arranged outside the end face of the guide roller 2, a cover sheet 24 made of elastic material is fixedly connected to the inner wall of the air path 22, the cover sheet 24 covers the air blowing hole 23, and one side of the cover sheet 24 can be pushed open by the air flow, such as the cover sheet 24 is fixed on three sides on one side contacting the inner wall of the air path 22, the air flow pushes open one side of the cover sheet 24, when the air flow pressure decreases, the cover sheet 24 elastically resets and covers and recloses, the rotating shaft 211 of the guide roller 2 is a hollow structure and is connected to the air blowing hole 23, and an input hole 212 is arranged on the outer side of the rotating shaft 211;

[0028] A plurality of inclined holes 25 are arranged on the outer circle of the guide roller 2, and the inclined holes 25 are connected with the interlayer cavity 21 and the air path 22. The distance between the inclined hole 25 located at one end of the outer surface of the guide roller 2 and the corresponding blowing device 4 is greater than the distance between the inner end of the inclined hole 25 and the corresponding blowing device 4. The outer circle of the guide roller 2 is arranged with an arc groove 26 that is the same length as itself, and at least two arc grooves 26 are arranged. The at least two arc grooves 26 correspond to the blowing devices 4 at both ends. If the blowing device 4 at the left end is adjusted to blow, an airflow away from the blowing device 4 at the left end is formed at the bottom of the ceramic insulating aluminum foil by the corresponding arc groove 26, and vice versa.

[0029] In this embodiment, on the one hand, the air leakage hole 48 is blocked, so that the airflow exerts thrust on the floating ring 3 to prevent the ceramic insulating aluminum foil from further deflecting. On the other hand, part of the airflow pushes open the cover sheet 24, and is blown out from the inclined hole 25 after passing through the air path 22 and the interlayer cavity 21, exerting an axial thrust in the air cavity formed on the bottom surface of the ceramic insulating aluminum foil, thereby pulling the ceramic insulating aluminum foil back and avoiding the edge of the ceramic insulating aluminum foil from continuously rubbing against the floating ring 3. The floating ring 3 is not relied on alone to push the ceramic insulating aluminum foil back, thereby avoiding damage to the edge of the ceramic insulating aluminum foil.

[0030] As an embodiment of the present invention, the inclined hole 25 is located in the arc-shaped groove 26, and a cavity is formed between the inclined hole 25 and the ceramic insulating aluminum foil. When a high-speed airflow is formed inside, the other end of the arc-shaped groove 26 is an open structure, and the airflow passing through will cause an adsorption effect, and the bottom of the ceramic insulating aluminum foil will be shifted sideways due to the flow of airflow, thereby achieving the purpose of flexibly moving the ceramic insulating aluminum foil and avoiding wear and damage to the edge of the ceramic insulating aluminum foil.
