Technical Field

[0001] The utility model belongs to the technical field of film processing equipment, in particular to a corona machine. Background Art

[0002] Release film refers to a film with distinguishable surface. It is non-sticky or slightly sticky when in contact with specific materials under limited conditions. It needs to go through multiple processes such as metal surface treatment, slitting, packaging, and molding during the production process. A corona machine is required for metal surface treatment. The corona machine is a surface pretreatment equipment for silicone rubber, plastic and other materials. It can prevent the raw materials from having printing color loss, loose composite adhesion, etc. during the production process, which affects product quality.

[0003] After searching, the publication number CN217395738U, the application date 2022.01.17 discloses an efficient film surface corona machine, including a bottom plate, a support column, the support column is provided with two groups, and the two groups of support columns are fixedly connected to the surface of the bottom plate; a corona box, the corona box is horizontally arranged at the top of the support column; a corona roller, the corona roller is rotatably arranged in the middle of the inner cavity of the corona box; a chute, the chute is provided with two groups, and the two groups of chute are respectively vertically arranged on both sides of the inner wall of the corona box. The efficient film surface corona machine provided by the utility model can introduce the film into the corona box through the corona box, and the bottom and top of the guiding film of the tensioning guide wheel can be attached to the surface of the corona roller.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0034] See also Figures 1 to 3 The utility model is a corona machine, comprising a frame 1 and a conveying roller 101 rotatably connected to the edge of one side of the inner side thereof, dust removal boxes 102 are installed at the edges of both sides of the upper surface and the lower surface of the frame 1, and a dust removal component 2 is arranged inside the dust removal box 102; the dust removal component 2 comprises an asynchronous motor 201 and a rotating shaft 2011 installed on its output shaft through a coupling, and the other end of the rotating shaft 2011 passes through a bearing on one side of the rear end face of the dust removal box 102 and is connected with a bearing on the front end face inside the dust removal box 102.

[0035] Specifically, a corona mechanism 103 is provided on the other side of the outer wall of the frame 1, and an electrostatic elimination roller 104 is provided on one side of the upper surface of the frame 1. A winding roller 202 is sleeved on the outer side of the outer wall of the rotating shaft 2011, and a dust collecting paper roll 203 is rolled up on the outer wall of the winding roller 202. The other end of the dust collecting paper roll 203 bypasses the bottom of the contact roller 204 and is wound on the outer side of the outer wall of the release roller 205. The front and rear ends of the contact roller 204 and the release roller 205 are rotatably connected to the inner wall of the dust removal box 102.

[0036] Furthermore, the dust removal box 102 and the dust removal component 2 are arranged in a one-to-one correspondence. The asynchronous motor 201 drives the rotating shaft 2011 to rotate under the action of the coupling, so that the winding roller 202 rotates and winds the used dust collecting paper roll 203. The new dust collecting paper roll 203 is sleeved on the outer wall of the release roller 205, and the adjacent contact rollers 204 are clamped on the outer sides of the upper and lower surfaces of the film.

[0037] The operation process of this embodiment is: first, the film to be corona treated is transported to the inside of the frame 1 through the conveying roller 101, and then enters into the dust removal box 102 located on the left side of the frame 1, and then the asynchronous motor 201 is started. The output shaft of the asynchronous motor 201 rotates through the coupling to drive the rotating shaft 2011 to rotate, and the rotation of the rotating shaft 2011 will drive the winding roller 202 on its outer wall to rotate, and pull out the dust collecting paper roll 203 wrapped on the outer wall of the release roller 205 at a uniform speed. At the same time, when the dust collecting paper roll 203 passes the bottom of the contact roller 204, it will contact the surface of the film, and the dust on its surface will adhere to the dust collecting paper roll 203, which can play a role in preliminary dust removal. After the film is treated by the corona mechanism 103, the dust removal component 2 on the far right will remove the dust from the corona treated film again, which can improve the dust removal efficiency and effect of the film, and at the same time avoid the film being stained with dust on its surface before corona treatment, affecting the corona treatment effect. Specific embodiment 2

[0039] See also Figure 1 , 4 5. Based on the specific embodiment 1, what is different from the first embodiment is that: a water cooling component 3 and an air cooling component 4 are provided, the water cooling component 3 includes a cooling box 301 and a water outlet pipe 3011 arranged at a corner on one side of its front end face, and the other end of the water outlet pipe 3011 is connected to a water pump 302 through a pipe joint; the air cooling component 4 includes a wind rack 401 and a mounting frame 402 embedded in the center position of the front and rear end faces thereof, a servo motor 403 is suspended on the inner wall of the mounting frame 402, and a fan blade 404 is installed on the output shaft of the servo motor 403, which solves the existing problem that if dust is attached to the surface of the film before corona, it will affect the corona effect, and at the same time, only the upper surface of the film is cooled, which will cause different cooling effects on the upper and lower surfaces, affecting the work efficiency.

[0040] Specifically, a water inlet pipe 3012 is arranged at a corner on one side of the rear end face of the cooling box 301, and the other end of the water inlet pipe 3012 is connected to the return pipe 3013 through a pipe joint, and the water outlet end of the water pump 302 is connected to the delivery pipe 3021 through a pipe joint. A lower cooling roller 303 and an upper cooling roller 304 are arranged on the top of the cooling box 301 from bottom to top, and a hollow shaft 305 is arranged at the inner center position of the lower cooling roller 303 and the upper cooling roller 304. The front and rear ends of the hollow shaft 305 respectively pass through the bearings on the end faces of the front fixed plate 306 and the rear fixed plate 307, and the other ends of the delivery pipe 3021 and the return pipe 3013 are respectively rotatably connected to the inside of the adjacent hollow shaft 305 through a three-way joint, and the bottoms of the front fixed plate 306 and the rear fixed plate 307 are fixed on the upper surface of the frame 1.

[0041] Furthermore, the pipe joint and the three-way joint both serve as pipeline connections. The operation of the servo motor 403 drives the fan blades 404 to rotate, and the direction of the air duct is in the front-to-back horizontal direction. The lower cooling roller 303 and the upper cooling roller 304 are located on the outer sides of the upper and lower surfaces of the film and are in close contact, which can improve the cooling effect and efficiency of the film. The front fixed plate 306 and the rear fixed plate 307 serve to limit and assist the rotation of the hollow shaft 305.

[0042] The operation process of this embodiment is as follows: after the film is corona treated, the film will be sent between the lower cooling roller 303 and the upper cooling roller 304. At this time, the water pump 302 is started, and the water pump 302 operates to extract the cooling water inside the cooling box 301 through the outlet pipe 3011, and then enters the hollow shaft 305 inside the lower cooling roller 303 and the upper cooling roller 304 through the conveying pipe 3021, and after cooling the lower cooling roller 303 and the upper cooling roller 304 to exchange heat, it returns to the cooling box 301 through the return pipe 3013 and the water inlet pipe 3012, so that the upper and lower surfaces of the film can be contact-cooled at the same time, and after water cooling, the film enters the wind rack 401. At this time, the servo motor 403 is started, and the output shaft of the servo motor 403 rotates to drive the fan blades 404 to rotate, wherein the generated air duct is in the horizontal direction, which can simultaneously cool the upper and lower surfaces of the film, thereby improving the cooling efficiency and effect of the film, and having high working efficiency.
