Description

Technical Field

[0001] The present application relates to the field of corona machines, and in particular, to a corona machine for conductive films. Background Art

[0002] A conductive film is a thin film with conductive function. During the production of conductive films, a corona machine is usually required to improve the printing effect on the product surface.

[0003] In the related art, the corona machine mainly includes a frame, a corona roller, and a bracket. The corona roller is rotatably connected to the frame, the bracket is slidably connected to the frame, and a number of electrode heads are provided on the bracket. To reduce the possibility of the electrode heads affecting the workers, a protective cover is also slidably connected to the frame, and the protective cover covers the electrode heads. When the corona machine needs to be used, the worker winds the product to be corona-treated around the corona roller, then manually adjusts the position of the bracket, that is, adjusts the position between the electrode heads and the workpiece, and then manually adjusts the position of the protective cover, and then the product can be corona-treated.

[0004] However, the positions of the electrode heads and the protective cover need to be manually adjusted, and they need to be adjusted separately, which is rather cumbersome, thus reducing the efficiency when using the corona machine for corona treatment. Summary of the Utility Model

[0005] In order to improve the problem of cumbersome operation when using the existing corona machine, the present application provides a corona machine for conductive films.

[0006] The present application provides a corona machine for conductive films, adopting the following technical solutions:

[0007] A corona machine for conductive films includes a frame and a corona roller. The corona roller is provided on the frame. A protective cover is provided above the corona roller at the top of the frame. A number of electrode heads are provided on the inner top of the protective cover. A support rod is provided on each side of the protective cover, and a waist hole extending in the vertical direction is provided on each side of the frame. The support rod passes through the waist hole and extends to the outside of the frame. A hydraulic rod is provided on the outer wall of each side of the frame. The push rod of the hydraulic rod is connected to the support rod, and the hydraulic rod is used to drive the support rod to slide in the waist hole.

[0008] By adopting the above technical solutions, the protective cover is driven by the hydraulic rod to lift the position of the protective cover, which is convenient for winding the film material around the corona roller. At the same time, the movement of the protective cover can drive the electrode heads to move synchronously, ensuring that when winding the film material, the electrode heads are far away from the corona roller. After the film material is wound, the electrode heads can approach the film material again, realizing the linkage between the protective cover and the electrode heads, simplifying the operation steps, and improving the operation efficiency.

[0009] Optionally, a loading roller is provided at the front end of the frame, and an unloading roller is provided at the rear end of the frame. The loading roller, the unloading roller and the corona roller are arranged in parallel. The loading roller and the unloading roller are at the same height and both are lower than the height of the corona roller.

[0010] By adopting the above technical solution, with the cooperation of the loading roller, the corona roller and the unloading roller, the film material can be reliably wound around the corona roller and kept in a tensioned state.

[0011] Optionally, an air extraction pipe is provided at the top of the protective cover. One end of the air extraction pipe is communicated with the inner side of the protective cover, and the other end of the air extraction pipe is communicated with an air extraction pump. The air extraction pump is used to extract the gas in the air extraction pipe.

[0012] By adopting the above technical solution, the setting of the air extraction pipe can extract gases such as ozone generated during the corona process and optimize the operation environment.

[0013] Optionally, a mounting frame is provided at the inner top of the protective cover. The side of the mounting frame facing the corona roller is arc-shaped, and a plurality of electrode heads are evenly distributed on the mounting frame;

[0014] The connection part of the air extraction pipe and the protective cover is located outside the mounting frame.

[0015] By adopting the above technical solution, the electrode heads are fixed by the mounting frame to ensure that the electrode heads can be in a reliable working state. Further, by selecting different mounting frames, the distance between the electrode heads and the film material can be adjusted, so as to ensure reliable corona effect.

[0016] Optionally, an observation port is provided on the outer side of the frame. The observation port is arc-shaped and is used to observe the electrode heads and the corona roller.

[0017] By adopting the above technical solution, the discharge state of the electrode heads and the corona effect state of a plurality of electrode heads on the film material can be observed through the observation port, so as to effectively control the corona process. If some electrode heads fail to work, the machine can be stopped in time for maintenance or replacement.

[0018] Optionally, a cover plate is provided at the lower end of the protective cover. The bottom of the cover plate is connected to the bottom of the protective cover through a hinge; support plates are provided on both sides of the protective cover. The support plates extend in the vertical direction and are flush with the side wall of the protective cover. Both sides of the cover plate are pressed on the support plates. A viewing window is also provided on the protective cover, and the viewing window extends along the length direction of the cover plate.

[0019] By adopting the above technical solution, the cover plate can play a role in covering the corona roller. After the equipment runs normally, the cover plate can be closed to prevent personnel or sundries from entering between the protective cover and the corona roller, improving the safety of the corona process. The operating condition of the corona roller inside the protective cover can be observed through the viewing window, which is convenient for timely parameter adjustment.

[0020] Optionally, a first through hole is provided on one side of the support plate facing the cover plate, and a nut is fixedly provided in the first through hole. The side of the nut facing the cover plate is flush with the outer wall of the support plate. A second through hole is provided on the side of the cover plate facing the support plate, and a screw rod is inserted into the second through hole. The screw rod is adaptively screwed into the nut.

[0021] By adopting the above technical solution, when the first through hole and the second through hole are aligned, the screw rod can be screwed into the second through hole and the first through hole, thereby realizing the cooperation between the screw rod and the nut. In this way, the cover plate can be screwed and fixed on the support plate by the screw rod, preventing the operator from accidentally opening the cover plate when the corona roller is running at high speed, and further improving the safety of the operation process.

[0022] Optionally, a guide plate is provided on the inner side of the cover plate. The guide plate is inclined towards the corona roller. The guide plate is connected to the cover plate by bolts. An arc plate is provided at the bottom of the guide plate, and the arc plate is used for the transition of the film material.

[0023] By adopting the above technical solution, the guide plate and the arc plate cooperate, so that the arc plate can press against the top of the film material, ensuring that the film material can be in a tensioned state, and further ensuring that the film material can pass through a plurality of electrode heads smoothly and at a uniform speed, improving the corona effect.

[0024] Optionally, the guide plate includes a vertical portion and an inclined portion. The bottom of the vertical portion is connected to the arc plate, the top of the vertical portion is connected to the bottom of the inclined portion, and a plurality of fixing holes are provided on both the vertical portion and the inclined portion. The bolt is inserted into any one of the fixing holes.

[0025] By adopting the above technical solution, selecting the fixing hole on the vertical portion or the inclined portion to connect with the bolt can adjust the overall angle of the guide plate and the arc plate. Selecting different fixing holes on the vertical portion or selecting different fixing holes on the inclined portion to connect with the bolt can adjust the overall height of the guide plate and the arc plate, ensuring that the arc plate can contact the film material at the best angle, pressing against the film material while reducing the wear on the film material.

[0026] In summary, the present application has the following beneficial effects:

[0027] 1. The protective cover and the electrode head are synchronously driven by a hydraulic rod. While achieving the protective function, the electrode head is brought closer to the film material, simplifying the operation steps and improving the working efficiency of the corona operation.

[0028] 2. By selecting different fixing holes on the guide plate for connection with bolts, the angles and heights of the guide plate and the arc plate relative to the film material are adjusted, thereby ensuring that the arc plate can reliably press against the top of the film material and play a guiding role for the film material.

[0035] The following will further elaborate on the present application in conjunction with the attached Figures 1-5 drawings.

[0036] Figure 1 is a schematic three-dimensional view of the present application Figure 1 , Figure 2 is a schematic three-dimensional view of the present application Figure 2. A corona machine for a conductive film, comprising a frame 1 and a corona roller 2. The corona roller 2 is arranged inside the frame 1. A loading roller 5 is provided at the front side of the frame 1, and an unloading roller 6 is provided at the rear side of the frame 1. The loading roller 5, the corona roller 2, and the unloading roller 6 are in a parallel state. The loading roller 5 and the unloading roller 6 have the same height and are both lower than the height of the corona roller 2. The film material is wound from the bottom of the loading roller 5 to the top of the corona roller 2, and then from the top of the corona roller 2 to the bottom of the unloading roller 6. In this way, after adjusting the height difference between the corona roller 2 and the loading roller 5 and the unloading roller 6, the film material can be in a tensioned state and be conveyed on the corona roller 2.

[0037] Figure 3 It is a reference diagram of the assembly state of the protective cover and the electrode head. See Figure 3 and in combination with Figure 1 , a protective cover 3 is provided at the top of the frame 1. The protective cover 3 covers the top of the corona roller 2. An installation frame 33 is detachably provided at the inner top of the protective cover 3. The side of the installation frame 33 facing the corona roller 2 is arc-shaped. In this way, after installing a number of electrode heads 4 on the side of the installation frame 33 facing the corona roller 2, the distances between different electrode heads 4 on the installation frame 33 and the film material can be kept consistent, ensuring that the corona operation is more accurate. Further, by selecting different installation frames 33, the distance between the electrode heads 4 and the film material can be reliably adjusted, improving the corona effect on the film material.

[0038] See Figure 1 and Figure 3 , a support rod 31 is provided on both sides of the protective cover 3, and a waist-shaped hole 11 is provided on both sides of the frame 1. The waist-shaped hole 11 extends in the vertical direction. One end of the support rod 31 is connected to the protective cover 3, and the other end of the support rod 31 passes through the waist-shaped hole 11 and extends to the outside of the frame 1. A hydraulic rod 12 is provided on the outer walls of both sides of the frame 1. The push rod of the hydraulic rod 12 is connected to the support rod 31. When the hydraulic rod 12 drives the support rod 31 to slide up and down in the waist-shaped hole 11, the support rod 31 can drive the protective cover 3 to move up and down. In this way, when winding the film material, the hydraulic rod 12 drives the protective cover 3 to move up, which can provide a larger working space. After the film material winding is completed, the hydraulic rod 12 drives the protective cover 3 to move down, which can realize the synchronous downward movement of the electrode heads 4. After the protective cover 3 completes the isolation and protection of the corona roller 2, the electrode heads 4 can be close to the film material, avoiding the problem of cumbersome operation caused by separate adjustment of the electrode heads 4 and the protective cover 3, and effectively improving the working efficiency of the corona operation.

[0039] See Figure 3, an air extraction pipe 32 is provided at the top of the protective cover 3. One end of the air extraction pipe 32 is connected to an air extraction pump, and the other end of the air extraction pipe 32 communicates with the inside of the protective cover 3. In this way, after the air extraction pump removes the gas in the air extraction pipe 32, a negative pressure will be formed in the air extraction pipe 32, and then gases such as ozone generated during corona will be extracted, optimizing the operating environment and preventing operators from inhaling ozone for a long time and damaging their health. Further, the connection between the air extraction pipe 32 and the protective cover 3 is located outside the mounting frame 33 and the electrode head 4, which can prevent the air extraction effect of the air extraction pipe 32 from affecting the normal operation of the electrode head 4, ensuring that the electrode head 4 can reliably perform corona on the film material.

[0040] Figure 4 It is a reference diagram of the separated state of the support plate and the cover plate. See Figure 4 and combine with Figure 1 , support plates 35 are provided on both sides of the bottom of the protective cover 3, and a cover plate 34 is provided at the lower end of the protective cover 3. The upper side of the cover plate 34 and the bottom of the protective cover 3 are connected by a hinge 341. The support plates 35 extend in the vertical direction and are flush with the side wall of the protective cover 3. A first through hole 351 is provided on one side of the support plate 35 facing the cover plate 34, and a second through hole 342 is provided on the side of the cover plate 34 facing the support plate 35. At the same time, a nut 352 is fixedly provided in the first through hole 351, and a screw 343 is inserted into the second through hole 342. In the natural state, the cover plate 34 presses on the support plate 35. At this time, the first through hole 351 and the second through hole 342 are in a coaxial state, and the screw 343 can be screwed into the nut 352. In this way, the locking effect on the cover plate 34 can be achieved, ensuring that the cover plate 34 cannot be easily opened during the stable progress of the corona operation, improving the safety during the operation process.

[0041] Figure 5 It is a reference diagram of the assembled state of the cover plate and the guide plate. See Figure 5 and combine with Figure 1, a guide plate 37 is provided inside the cover plate 34. The guide plate 37 extends along the length direction of the cover plate 34 and is connected to the cover plate 34 by bolts 371. The guide plate 37 is inclined towards the direction of the corona roller 2. A guide plate 37 is provided on the side of the guide plate 37 close to the conductive roller. The guide plate 37 and the arc plate 372 are of an integrally formed structure. The guide plate 37 includes a vertical portion 373 and an inclined portion 374. The bottom of the vertical portion 373 is connected to the arc plate 372, and the top of the vertical portion 373 is connected to the bottom of the inclined portion 374. A number of fixing holes 375 are provided on both the vertical portion 373 and the inclined portion 374. When installing the guide plate 37, any one of the fixing holes 375 can be selected for the bolt 371 to pass through. When selecting between the fixing holes 375 on the inclined portion 374 and the vertical portion 373, the inclination angle of the arc plate 372 can be adjusted. When selecting a number of the fixing holes 375 on the inclined portion 374 or selecting a number of the fixing holes 375 on the vertical portion 373, the height of the arc plate 372 can be adjusted. In this way, it is ensured that the arc plate 372 can reliably abut against the top of the film material, playing a guiding role in the conveyance of the film material and minimizing the friction between the arc plate 372 and the film material, reducing the wear of the film material.

[0042] See Figure 1 and Figure 3 , a viewing window 36 is further provided on the protective cover 3. A number of viewing windows 36 extend along the length direction of the cover plate 34. An arc-shaped observation port 13 is provided on the side wall of the frame 1. Through the viewing window 36 and the observation port 13, the winding and conveying conditions of the film material in the protective cover 3 and the working state of the electrode head 4 can be reliably observed, facilitating the adjustment of the operating parameters of the corona machine or the timely replacement of components such as the electrode head 4, ensuring the reliability of the corona operation on the film material.

[0043] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
