Abstract
Description
Technical Field
[0001] This utility model relates to the field of corona treatment technology for printing and packaging, specifically to a corona treatment machine for printing and packaging. Background Technology
[0002] A corona treatment machine is a surface treatment device that generates plasma discharge by applying a high-voltage electric field to the surface of a material, thereby causing chemical reactions and physical changes on the surface. This enhances the wettability of the material surface. After treatment, the surface tension of the substrate increases, allowing inks, adhesives, coatings, etc., to adhere better to the material surface, improving the quality of printing, laminating, coating and other processes, and avoiding problems such as printing color spillage, weak lamination, and uneven coating.
[0003] In the process of realizing this utility model, the inventors discovered the following problems with the existing technology: 1. The ventilation system in the printing and packaging workshop is imperfect, and a large number of dust particles are suspended in the air. When the corona treatment machine is running, the airflow will carry dust to adhere to the surface of the equipment. Due to the dust and other impurities on the material surface, the ink will be hindered from adhering evenly to the material surface, resulting in spots, blurring, and uneven color of the printed pattern. During the lamination process, the dust on the material surface will affect the bonding effect between the glue and the material, resulting in a decrease in the lamination strength and easy delamination, bubbling, and other problems, affecting the sealing and protection of the packaging; 2. The printing and packaging industry uses a wide variety of materials, and different materials have different requirements for corona treatment. The existing electrodes are fixed in one position by screws. In different printing and packaging processes, there are also different requirements for the intensity and uniformity of corona treatment. For example, when printing high-quality patterns, a stronger corona treatment effect is required, while in the lamination process, a more uniform corona treatment is required. The electrode position cannot be adjusted, so it cannot better adapt to the surface characteristics of different materials and meet the needs of different processes. Utility Model Content
[0004] The purpose of this utility model is to provide a corona treatment machine for printing and packaging, to solve the problems mentioned in the background art, such as airflow causing dust to adhere to the surface of the equipment, and the dust and other impurities on the material surface hindering the uniform adhesion of ink to the material surface, resulting in spots, blurring, and uneven color in the printed pattern. Furthermore, during the lamination process, dust on the material surface affects the bonding effect between the adhesive and the material. To achieve the above objectives, this utility model provides the following technical solution: a corona treatment machine for printing and packaging, including a fixed leg, a U-shaped plate mounted on the top of the fixed leg by screws, a drive shaft rotatably connected inside the U-shaped plate, an output shaft of a second servo motor mounted on the rear of the drive shaft by bolts, a belt drive connection between the drive shaft and the driven shaft, a control cabinet attached to the front of the U-shaped plate, a frame above the U-shaped plate, and a slide rail on one side of the frame;
[0005] An observation window is embedded in the upper part of the frame. A limiting ring is provided inside the observation window. A second threaded rod is threadedly connected to the inner part of the limiting ring. A fixing ring is threadedly connected to the outer wall of the second threaded rod. A support plate is threadedly installed below the second threaded rod. An electrode is provided below the support plate. A connecting plate is installed on one side of the frame by screws. A first threaded rod is threadedly connected to the inner part of the connecting plate. A rotating handle is provided on one side of the first threaded rod. A protective pad is glued to the other side of the first threaded rod. A retaining plate is welded below the support leg of the frame.
[0006] The housing of the first servo motor is mounted on one side of the slide rail by screws. The output shaft of the first servo motor is mounted on the third threaded screw by bolts. A slide rod is mounted inside the slide rail by screws. A slider is threadedly connected to the outer wall of the third threaded screw. A mounting plate is mounted in front of the slider by screws. A vacuum cleaner is mounted inside the mounting plate by screws.
[0007] More preferably, the internal structure of the limiting retaining ring is consistent with the external structural dimensions of the second threaded screw, and the internal structural dimensions of the fixing retaining ring are consistent with the external structural dimensions of the second threaded screw.
[0008] More preferably, the frame is provided with observation windows at the front, rear, left, right and top, and the rear observation window is provided with a rectangular slide, with the vacuum cleaner inlet fitting into the slide opening of the observation window.
[0009] More preferably, the connecting plate is an "L" shaped plate, and the internal structural dimensions of the connecting plate are consistent with the external structural dimensions of the first threaded rod. Furthermore, a number of rectangular protrusions are provided on one side of the protective pad, and the protective pad is made of silicone material.
[0010] In a further preferred embodiment, the third threaded screw forms a rotating structure via the first servo motor, and the external structural dimensions of the third threaded screw are consistent with the central thread dimension of the slider. The slider has three vertically distributed circular slots inside, with a nut in the central slot and smooth holes on both sides that fit against the outer wall of the slider rod. The slider forms a horizontal sliding structure via the third threaded screw, and the slider is fixed to the mounting plate with screws. The vacuum cleaner is also mounted on the mounting plate with screws, and the vacuum cleaner forms a horizontal sliding structure with the slider via the mounting plate.
[0011] More preferably, the external structural dimensions of the card plate are consistent with the dimensions of the holes and slots in the U-shaped plate.
[0012] More preferably, the drive shaft forms a rotating structure via a second servo motor, the conveyor belt forms a rotating structure via the drive shaft, and the driven shaft forms a rotating structure via the conveyor belt.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] In this invention, a first servo motor drives a third threaded screw to rotate. Since the external structural dimensions of the third threaded screw are consistent with the thread dimensions in the middle of the slider, and the smooth holes on both sides of the slider fit against the outer wall of the slide rod, the slider can slide horizontally under the drive of the third threaded screw and move under the guidance and stabilization of the slide rod. Because the slider, mounting plate, and vacuum cleaner are fixed in sequence, the horizontal position of the vacuum cleaner can be flexibly adjusted according to different printing and packaging positions and the dust distribution generated during the corona treatment process, so as to more effectively remove dust and impurities, improve the cleanliness of the equipment, and ensure the effect of corona treatment.
[0015] In this invention, the internal structure of the limiting ring is consistent with the external structure of the second threaded rod, and the internal structure of the fixing ring is also consistent with the second threaded rod. By rotating the second threaded rod, the height of the electrode can be precisely adjusted. When the thickness and size of the printed packaging change, it can adapt to different processing requirements and ensure the best effect of corona treatment. The limiting ring can limit the movement range of the second threaded rod to prevent excessive movement, and the fixing ring can fix it in a specific position to ensure that the distance between the electrode and the printed packaging is always appropriate, thereby improving the stability and consistency of corona treatment. The connecting plate is an "L" shaped plate with internal structure dimensions consistent with the external structure dimensions of the first threaded rod. When the plate slides to the appropriate position on the U-shaped plate, turning the handle can drive the first threaded rod to rotate, pushing the anti-slip pad towards the U-shaped plate. The protective pad is made of silicone and has rectangular protrusions, which increases the friction between it and the U-shaped plate, effectively preventing the plate from moving and achieving stable fixation of the frame. This ensures that the equipment will not move during operation and ensures accurate processing of the printed packaging. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1 to 4 This utility model provides a technical solution: a corona treatment machine for printing and packaging, including a fixed leg 1, a U-shaped plate 4 installed above the fixed leg 1 by screws, a drive shaft 5 rotatably connected inside the U-shaped plate 4, an output shaft of a second servo motor 6 installed behind the drive shaft 5 by bolts, the drive shaft 5 and the driven shaft 8 being connected by a conveyor belt 9, a control cabinet 7 attached to the front of the U-shaped plate 4, a frame 2 provided above the U-shaped plate 4, and a slide rail 3 provided on one side of the frame 2;
[0023] An observation window 208 is embedded in the upper part of the frame 2. A limiting ring 210 is provided inside the observation window 208. A second threaded rod 201 is threadedly connected inside the limiting ring 210. A fixing ring 211 is threadedly connected to the outer wall of the second threaded rod 201. A support plate 202 is threadedly installed below the second threaded rod 201. An electrode 209 is provided below the support plate 202. A connecting plate 207 is installed on one side of the frame 2 by screws. A first threaded rod 204 is threadedly connected inside the connecting plate 207. A rotating handle 203 is provided on one side of the first threaded rod 204. A protective pad 205 is glued to the other side of the first threaded rod 204. A clamping plate 206 is welded below the support leg of the frame 2.
[0024] The housing of the first servo motor 305 is mounted on one side of the slide rail 3 by screws. The output shaft of the first servo motor 305 is mounted on the third threaded screw 304 by bolts. The slide rail 3 is mounted on the inside of the slide rail 3 by screws. The outer wall of the third threaded screw 304 is threaded to a slider 306. The front of the slider 306 is mounted on a mounting plate 301 by screws. The vacuum cleaner 302 is mounted on the inside of the mounting plate 301 by screws.
[0025] In this embodiment, as Figure 3As shown, the internal structure of the limiting ring 210 is consistent with the external structure of the second threaded rod 201, and the internal structure of the fixing ring 211 is consistent with the external structure of the second threaded rod 201. In the application of the corona treatment machine for printing and packaging, the internal structure of the limiting ring 210 is consistent with the external structure of the second threaded rod 201. The inside of the limiting ring 210 is a smooth surface that fits against the second threaded rod 201. The internal thread structure of the fixing ring 211 is also consistent with the external structure of the second threaded rod 201. The observation window 208 is equipped with a limiting ring 210. The lower part of the second threaded rod 201 is threadedly connected to the support plate 202. The purpose of adjusting the height is to allow the electrode 209 to be adjusted according to the height of different printed packages on the conveyor belt 9 to ensure the best corona treatment effect. Specifically, when the printed package... When the thickness, size, etc. change, the height of the electrode 209 can be adjusted to adapt to different processing requirements. By rotating the second threaded screw 201, the position of the second threaded screw 201 in the vertical direction can be changed. Since the second threaded screw 201 is threadedly connected to the support plate 202, when the second threaded screw 201 moves up and down, it will drive the support plate 202 to move up and down synchronously. The electrode 209 is mounted on the support plate 202, thus realizing the adjustment of the height of the electrode 209. The limiting ring 210 can limit the movement range of the second threaded screw 201 to prevent it from moving excessively or exceeding the safe range. The fixing ring 211 can fix the second threaded screw 201 in a specific position to ensure that the adjusted height is stable and reliable, thereby ensuring that the distance between the electrode 209 and the printing packaging is always in a suitable state during the corona treatment process, so as to achieve a good corona treatment effect.
[0026] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the frame 2 has observation windows 208 on the front, back, left, right, and top. The rear observation window 208 has a rectangular slide, and the vacuum cleaner 302's feed nozzle fits into the slide opening of the observation window 208. The presence of observation windows 208 on the front, back, left, right, and top of the frame 2 provides operators with a comprehensive viewing angle, facilitating real-time monitoring of the equipment's internal operation. The rectangular slide of the rear observation window 208, with the vacuum cleaner 302's feed nozzle fitting into the slide opening, allows the vacuum cleaner 302 to perform vacuuming operations more stably, ensuring the cleanliness of the equipment's interior. A retaining plate 206 is located at the bottom of the frame 2, sliding on the U-shaped plate 4. The movable frame 2, which adjusts its horizontal position, can be adjusted according to different printing and packaging needs to better match the printing and packaging, thereby improving the adaptability and efficiency of the equipment. When the horizontal position of the frame 2 needs to be adjusted, the card plate 206 is pushed to slide on the U-shaped plate 4. Since the card plate 206 is connected to the frame 2, the movement of the card plate 206 will drive the frame 2 to move synchronously. In this way, the frame 2 can be adjusted to a suitable horizontal position according to the specific printing and packaging situation, so as to ensure that the equipment can accurately process the printing and packaging. At the same time, the adjustment process can be observed in real time through the observation window 208 to ensure the accuracy of the adjustment.
[0027] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the connecting plate 207 is an "L"-shaped plate, and the internal structural dimensions of the connecting plate 207 are consistent with the external structural dimensions of the first threaded screw 204. The protective pad 205 has several rectangular protrusions on one side and is made of silicone. After the clamping plate 206 is properly positioned, it can be stably fixed on the U-shaped plate 4, preventing movement during equipment operation and ensuring normal operation of the equipment and accurate processing of printing and packaging. When the clamping plate 206 slides to the appropriate position on the U-shaped plate 4, the handle 203 is rotated clockwise. The rotation of the handle 203 causes the first threaded screw 204 to rotate. Since the internal structural dimensions of the connecting plate 207 are consistent with the external structural dimensions of the first threaded screw 204, the rotation of the first threaded screw 204 will push the protective pad 205 to move towards the U-shaped plate 4. The protective pad 205 is made of silicone and has several rectangular protrusions on one side, which increases the friction between it and the U-shaped plate 4. When the four protective pads 205 are pressed against the U-shaped plate 4 at the same time, the friction generated can effectively prevent the movement of the clamping plate 206 and achieve a stable fixing effect.
[0028] In this embodiment, as Figure 4As shown, the third threaded screw 304 forms a rotating structure via the first servo motor 305, and the external structural dimensions of the third threaded screw 304 are consistent with the central thread dimension of the slider 306. The slider 306 has three vertically distributed circular slots inside, with a nut in the central slot and smooth openings on both sides that fit against the outer wall of the slide rod 303. The slider 306 forms a horizontal sliding structure via the third threaded screw 304. The slider 306 is fixed to the mounting plate 301 with screws, and the vacuum cleaner 302 is mounted to the mounting plate 301 with screws. The vacuum cleaner 302 forms a horizontal sliding structure with the slider 306 via the mounting plate 301. The position of the vacuum cleaner 302 can be flexibly adjusted according to different printing and packaging locations and dust distribution during corona treatment to ensure more effective removal of dust and impurities, improving the cleanliness of the equipment. To ensure the effectiveness of corona treatment and adapt to the cleaning needs of printed packaging of different sizes and shapes during the corona treatment process, thereby improving the versatility and adaptability of the equipment, the first servo motor 305 drives the third threaded screw 304 to rotate. Since the external structural dimensions of the third threaded screw 304 are consistent with the thread dimensions in the middle of the slider 306, when the third threaded screw 304 rotates, it will drive the slider 306 to slide horizontally along the third threaded screw 304. At the same time, the smooth holes on both sides of the slider 306 fit against the outer wall of the slide bar 303, which plays a role in guiding and stabilizing the movement of the slider 306. Since the slider 306 is fixed to the mounting plate 301 by screws, and the vacuum cleaner 302 is mounted on the mounting plate 301, when the slider 306 slides horizontally, it drives the vacuum cleaner 302 to slide horizontally as well, thereby realizing the adjustment of the horizontal position of the vacuum cleaner 302.
[0029] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the external structural dimensions of the card plate 206 are consistent with the dimensions of the slots in the U-shaped plate 4; the card plate 206 can slide smoothly in the slots in the U-shaped plate 4 to adjust the horizontal position of the frame 2. At the same time, this consistent size design makes the card plate 206 more stable when moving in the U-shaped plate 4, without shaking or shifting, providing a stable support structure for subsequent corona treatment of printing and packaging.
[0030] In this embodiment, as Figure 1 and Figure 2As shown, the drive shaft 5 forms a rotating structure via the second servo motor 6, and the conveyor belt 9 forms a rotating structure via the drive shaft 5, while the driven shaft 8 forms a rotating structure via the conveyor belt 9. After the second servo motor 6 starts, it drives the drive shaft 5 to rotate. Since the conveyor belt 9 is in contact with the drive shaft 5, the rotation of the drive shaft 5 will drive the conveyor belt 9 to move. The conveyor belt 9 is in contact with the driven shaft 8, and under the drive of the conveyor belt 9, the driven shaft 8 also rotates. In this way, the second servo motor 6 provides power to drive the drive shaft 5, the conveyor belt 9 and the driven shaft 8 to rotate in sequence, realizing the continuous conveying of printing and packaging on the conveyor belt 9, and providing a stable material transfer path for the corona treatment process.
[0031] The method of use and advantages of this utility model: The corona treatment machine for printing and packaging operates as follows:
[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, firstly, based on the height of the printed packaging on the conveyor belt 9, the control cabinet 7 issues a command to control the electrode 209 below the support plate 202. Since the limiting ring 210 has a smooth surface that matches the external structural dimensions of the second threaded rod 201, and the internal thread structure dimensions of the fixing ring 211 also match the external structural dimensions of the second threaded rod 201, the lower part of the second threaded rod 201 is threadedly connected to the support plate 202. The second threaded rod 201 can be rotated. When the second threaded rod 201 is rotated, it moves vertically. Because the second threaded rod 201 is threadedly connected to the support plate 202, it drives the support plate 202 to move up and down synchronously. The electrode 209 is mounted on the support plate 202, thus achieving… The height of electrode 209 can be adjusted to adapt to different printing and packaging height requirements, ensuring optimal corona treatment. A limiting ring 210 restricts the movement range of the second threaded rod 201, preventing excessive movement or exceeding safe limits. A fixing ring 211 secures the second threaded rod 201 in a specific position, ensuring stable and reliable height adjustment. Based on different printing and packaging needs, the horizontal position of frame 2 is adjusted, pushing the card plate 206 to slide on the U-shaped plate 4. Since card plate 206 is connected to frame 2, its movement causes frame 2 to move synchronously. The adjustment process can be observed in real-time through observation windows 208 on the front, back, left, right, and top of frame 2, ensuring accuracy and better performance. Used in conjunction with printing and packaging equipment, this system improves adaptability and efficiency. After the card plate 206 slides onto the U-shaped plate 4 to the appropriate position, the handle 203 is turned clockwise. This rotation of the handle 203 causes the first threaded rod 204 to rotate. Since the connecting plate 207 is an "L"-shaped plate and its internal dimensions match the external dimensions of the first threaded rod 204, the rotation of the first threaded rod 204 pushes the protective pad 205 towards the U-shaped plate 4. The protective pad 205 is made of silicone and has several rectangular protrusions on one side, increasing friction with the U-shaped plate 4. When all four protective pads 205 simultaneously press against the U-shaped plate 4, the resulting friction effectively prevents the card plate 206 from moving, thus achieving a stable and fixed frame. Based on the different printing and packaging locations and the dust distribution generated during the corona treatment process, the first servo motor 305 is controlled by the control cabinet 7. The first servo motor 305 drives the third threaded screw 304 to rotate. Since the external structural dimensions of the third threaded screw 304 are consistent with the central thread dimension of the slider 306, and the slider 306 has three vertically distributed circular slots inside, with a nut in the central slot that engages with the third threaded screw 304, and smooth, hollow sides that fit against the outer wall of the slide bar 303, the slider 306 will slide horizontally under the drive of the third threaded screw 304. Furthermore, since the slider 306 is fixed to the mounting plate 301 with screws, and the vacuum cleaner 302 is mounted to the mounting plate 301 with screws, the slider 306 will slide horizontally under the drive of the third threaded screw 304.Therefore, the horizontal sliding of slider 306 will cause vacuum cleaner 302 to move horizontally, adjusting vacuum cleaner 302 to a suitable horizontal position to ensure more effective removal of dust and impurities, improving the cleanliness of the equipment, and thus ensuring the effect of corona treatment. The second servo motor 6 is adjusted via control cabinet 7. After starting, the second servo motor 6 drives the drive shaft 5 to rotate. Since the conveyor belt 9 forms a rotating structure through the drive shaft 5, the rotation of the drive shaft 5 will drive the conveyor belt 9 to move. The driven shaft 8 also forms a rotating structure through the conveyor belt 9, and under the drive of the conveyor belt 9, the driven shaft 8 also rotates. According to the size of the printed packaging and the process requirements of corona treatment, the speed and direction of the second servo motor 6 are adjusted via control cabinet 7, thereby adjusting the rotation state of the drive shaft 5, and further adjusting the position and conveying speed of the conveyor belt 9 to ensure that the printed packaging can be accurately conveyed to the corona treatment position.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
