Description

Technical Field

[0001] This utility model relates to the field of corona machine technology, and in particular to a pull-out air-cooled corona machine. Background Technology

[0002] Corona treatment machines are frequently used to solve problems such as printing color fading, weak material adhesion, uneven coating delamination, and poor color saturation or failure to adhere properly. These problems are all caused by insufficient ink adhesion. Therefore, corona treatment improves surface adhesion, roughens the material surface, and increases surface tension, allowing inks, adhesives, and coatings to bond better to the treated surface. Simultaneously, the ozone generated during the corona process alters the molecular structure of the material surface, changing it from non-polar to polar. This ensures long-lasting color saturation and a clean print, achieving ideal printing and bonding results.

[0003] Existing corona machines, such as the forced air-cooled corona machine disclosed in Chinese utility model CN218660449U, assemble various parts such as a corona material conveying mechanism, a fixed bracket, ceramic electrodes, a discharge body, and a fan together. The fixed bracket is fixed to one side of the corona material conveying mechanism, and multiple ceramic electrodes are fixed on the fixed bracket for operation. Over time, the ceramic electrodes often malfunction and require repair or replacement. However, since the ceramic electrodes are fixed inside the corona machine, once a problem occurs, the user must disassemble the entire corona machine to repair or replace the parts. This complicated disassembly process not only wastes the user's time but also easily leads to the loss of some small parts. Utility Model Content

[0004] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to design a pull-out air-cooled corona machine. The corona device, which includes multiple ceramic electrodes, a fixed bracket and a connecting plate, is slidably installed inside the machine cover. This makes it convenient for users to pull out the fixed bracket containing multiple ceramic electrodes for inspection or replacement, which saves a lot of time and avoids the problem of small parts being lost during the disassembly of the corona machine.

[0005] To achieve the above objectives, this utility model provides a retractable air-cooled corona machine, including a machine cover, an electrical device located at the front end of the machine cover, and an air-cooling device, a corona device, and a conveying device arranged sequentially from top to bottom on the machine cover.

The air-cooling plate has at least one sliding groove.

[0007] Furthermore, the corona device includes: a fixed bracket, a plurality of ceramic electrodes, a first connecting plate and a second connecting plate. The fixed bracket is located directly below the air-cooled plate and has a protrusion that cooperates with the sliding groove.

The second connecting plate is fixedly connected to the rear plate. The plurality of ceramic electrodes are arranged around the fixed bracket and facing the conveying device. The front and rear ends of the plurality of ceramic electrodes are fixedly connected to the first connecting plate and the second connecting plate, respectively.

[0008] Furthermore, the conveying device includes: a corona roller and a conveying roller arranged horizontally below the corona roller, both the corona roller and the conveying roller being rotatably disposed between the front plate and the rear plate, with the corona roller located directly below a plurality of ceramic electrodes.

[0009] Furthermore, the power supply device includes: a plug, a protective shell, and an elastic conductive sheet. The front panel of the hood is also provided with a third through hole. The plug is embedded in the third through hole and both ends of the plug are exposed on the outer surface of the front panel of the hood.

The elastic conductive sheet is embedded in the first connecting plate and is exposed on the front end face of the first connecting plate. The elastic conductive sheet is in abutting contact with the rear end of the plug.

[0010] Furthermore, the machine cover has openings on both the left and right sides, and both openings are flush with the gap between the corona roller and the conveyor roller.

[0011] Furthermore, the top wall of the hood is a visible panel.

[0012] Furthermore, the rear panel of the hood is provided with a handle and a cover plate. The cover plate covers the first through hole and is located at the rear end of the rear panel, and the handle is fixed to the rear end of the cover plate.

[0019] like Figure 1-3As shown, this utility model provides a pull-out air-cooled corona machine, including a cover 1, an air-cooling device 2, a corona device 3, and a conveying device 4 arranged sequentially from top to bottom on the cover, and an electrical device 5 located at the front end of the cover 1. The air-cooling device 2 is provided with at least one sliding groove, the corona device 3 is provided with a protrusion that cooperates with the sliding groove, and the rear plate 12 of the cover 1 is provided with a first through hole 121. The first through hole 121 is flush with the corona device 3, and the width and height of the first through hole 121 are greater than the width and height of the corona device 3, respectively. Through the cooperation of the sliding groove and the protrusion, the corona device 3 can be slidably mounted on the air-cooling device 2 in the front-to-back direction. When the corona device 3 slides to the rear end, it can pass through the first through hole 121 and be completely removed from the cover 1, which facilitates the user to inspect or replace the internal parts of the corona device 3 in real time. In this embodiment, only two sliding grooves and protrusions that cooperate with the sliding grooves are provided. However, in other embodiments, the number of sliding grooves can be adjusted according to the size, material and weight of the parts, so that the sliding cooperation between the corona device and the air-cooling device is more stable and firm.

[0020] The air-cooling device 2 includes an air-cooling plate 21, a controller 22, and an air outlet pipe 23. The front and rear ends of the air-cooling plate 21 are fixedly connected to the front plate 11 and the rear plate 12, respectively. The horizontally arranged air-cooling plate 21 forms an air outlet chamber A with the top wall of the machine cover 1. The controller 22, which is used to monitor the air pressure inside the machine cover 1, is located on the air-cooling plate 21 and in the air outlet chamber A. The front plate 11 of the machine cover 1 is provided with a second through hole 111. The air outlet pipe A is connected to the air outlet chamber A through the second through hole 111. The air-cooling plate 21 forms a corona working chamber B with the bottom wall of the machine cover 1. The corona device 3 and the conveying device 4 are both located in the corona working chamber B. The corona working chamber B is connected to the air outlet chamber A. The air-cooling plate 21 is provided with at least one sliding groove. Because the corona machine generates a lot of heat when it is working, excessive accumulation of hot air inside the hood 1 can cause the temperature to become too high and damage the product. Therefore, an external fan is connected to the air duct 23. The hot air inside the hood 1 can flow from the corona working chamber B to the air outlet chamber A, and then through the second through hole 111 to the air outlet duct A and be sucked out. If the external fan malfunctions and causes a large amount of hot air to accumulate inside the hood 1, the controller 22 will detect that the air pressure in the air outlet chamber A is too high and issue an alarm to remind the user that the temperature of the corona machine is too high and the external fan may be malfunctioning, so that the user can monitor the operation of the corona machine.

[0021] The corona device 3 includes: a fixed bracket 31, several ceramic electrodes 32, a first connecting plate 33, and a second connecting plate 34. The fixed bracket 31 is located directly below the air-cooled plate 21 and has a protrusion that mates with the sliding groove. The first connecting plate 33 and the second connecting plate 34 are fixedly connected to the front and rear ends of the fixed bracket 31, respectively. The second connecting plate 34 is fixedly connected to the rear plate 12. Several ceramic electrodes 32 are fixed around the conveying device 4 on the fixed bracket 31 and facing directly downwards from the conveying device 4. The front and rear ends of the several ceramic electrodes 32 are fixedly connected to the first connecting plate 33 and the second connecting plate 34, respectively. This design structure connects the several ceramic electrodes 32, the fixed bracket 31, the first connecting plate 33, and the second connecting plate 34 into a whole, facilitating disassembly by the user.

[0022] The conveying device 4 includes a corona roller 41 and a conveyor roller 42 horizontally arranged directly below the corona roller 41. Both the corona roller 41 and the conveyor roller 42 are rotatably disposed between the front plate 11 and the rear plate 12. The corona roller 41 is located directly below a plurality of ceramic electrodes 32. Openings are provided on both the left and right sides of the machine cover 1, and the openings are flush with the gap between the corona roller 41 and the conveyor roller 42 used for conveying products. This allows products to be corona-treated to be conveyed in and out of the conveying device 4. That is, the products to be corona-treated are conveyed to the conveyor roller 42 through one side of the machine cover 1, and then sent to the corona roller 41 via the conveyor roller 42 and rotate with the corona roller 41. After being corona-treated by the plurality of ceramic electrodes 32 on the upper surface of the corona roller, the products are sent out of the corona treatment chamber B.

[0023] The power supply device 5 includes a protective shell 51, a plug 52, and an elastic conductive sheet 53. The front panel 11 of the hood also has a third through hole 112. The plug 52 is embedded in the third through hole 112, with both ends of the plug 52 exposed on the outer surface of the front panel 11. The protective shell 51 surrounds the front end of the plug 52 and is located on the front face of the front panel 11. The elastic conductive sheet 53 is embedded in the first connecting plate 33 and exposed on the front face of the first connecting plate 33. The elastic conductive sheet 53 makes contact with the rear end of the plug 52. The protective shell 51 not only prevents the plug 52 from coming into contact with water, but also prevents the plug 52 from being damaged by impacts during the handling of the corona machine, thus improving the safety of using the corona machine.

[0024] Preferably, the top wall of the cover 1 is a viewing panel, which allows the user to easily observe the condition of the air outlet chamber and the numerical display of the controller 22.

[0025] Preferably, the rear panel 12 of the casing is provided with a cover plate 6 and a handle 7. The cover plate 6 is located at the rear end of the rear panel 12 and covers the first through hole 121. The handle 7 is fixed to the rear end of the cover plate 6. The cover plate 6 completely covers the first through hole 121, which facilitates the external fan to better draw hot air from inside the casing 1, making the product's appearance more concise and beautiful. The user can pull the handle 7 to pull out the corona device 3, providing convenience for the user. As a preferred solution, the handle 7 is provided with heat insulation material. If the fan malfunctions and the temperature of the corona device 3 becomes too high, the heat insulation material can prevent the user from being burned.

[0026] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
