Description

Technical Field

[0001] This utility model relates to the technical field of paper cup processing equipment, specifically a plasma treatment device for the surface of paper cups. Background Technology

[0002] In the automated production of paper cups, the bonding quality of the cup seams directly affects the product's sealing performance and structural strength. To improve bonding strength, plasma treatment technology is commonly used to pretreat the surfaces of the paper cups to be bonded. This technology generates plasma through ionized gas, effectively removing surface contaminants and increasing the surface energy of the material, thereby enhancing the wettability and adhesion of adhesives or hot-melt materials.

[0003] While some paper cup machines have integrated plasma treatment devices, they mostly use a fixed installation structure. The position of the plasma nozzle is not adjustable or has a limited adjustment range. This makes it difficult to ensure that the plasma beam accurately acts on the treatment area of ​​the paper cup seam when producing paper cups of different diameters. Especially when changing to small-diameter or large-diameter cups, the distance and angle between the nozzle and the treatment surface shift, resulting in uneven surface treatment or untreated areas. This affects the bonding effect and makes defects such as bursting and false bonding still easy to occur. The equipment has poor versatility, the adjustment process is cumbersome, and it affects production efficiency and product quality stability. Utility Model Content

[0004] The purpose of this invention is to provide a plasma treatment device for paper cup surfaces, in order to solve the problems mentioned in the background art, such as the fixed position of the plasma nozzle and the difficulty in adjustment, which makes it difficult to ensure the processing accuracy when producing paper cups of different specifications, and easily leads to defects such as bursting and false sticking.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a plasma treatment device for paper cup surfaces, comprising a frame, a support platform on the base plate of the frame, a sliding seat driven by a transverse guide rail at the top of the frame, a plasma treatment unit consisting of a plasma generator and an ion nozzle mounted on the sliding seat, a rotating mechanism consisting of a rotating bracket and a rotating disk below the sliding seat, a support plate at the bottom of the rotating mechanism, a dynamic plate with an adjustable tilt angle on the support plate, and a fixing sleeve for mounting the ion nozzle at the front end of the dynamic plate.

[0006] Preferably, the support plate has a rectangular notch, and both sides of the bottom end of the dynamic plate are connected to the inner walls of the rectangular notch of the support plate through a rotating shaft. The upper part of the rectangular notch of the support plate is provided with a wedge-shaped push block, and a vertically distributed push cylinder is installed on one side of the outside of the support plate.

[0007] Preferably, the output end of the push cylinder is fixedly connected to one side of the wedge-shaped push block via a connector, and an elastic limiting member is connected between the top end of the dynamic plate and the upper end of the rectangular notch of the support plate.

[0008] Preferably, the rotating bracket and the rotating disk are connected at their center by a bearing, and a rotating motor is installed at the center of the top of the rotating bracket.

[0009] Preferably, both sides of the fixing sleeve are connected to the outer wall of the dynamic plate through vertical guide rails, and locking rings are welded and fixed at both the upper and lower ends of the fixing sleeve.

[0010] Preferably, the bottom end of the rotating disk extends outside the rotating bracket, and the support plate is vertically welded and fixed to the bottom of the rotating disk.

[0011] Compared with existing technologies, the beneficial effects of this utility model are: the plasma treatment device for paper cup surfaces achieves flexible adjustment of the nozzle position, ensuring precise treatment of the seams of paper cups of different sizes, effectively improving bonding quality, with a simple structure and strong applicability. The device achieves nozzle positioning adjustment along the paper cup seam direction by moving the sliding seat on the transverse guide rail. Combined with the rotating mechanism consisting of the rotating bracket and the rotating disk, it drives the support plate and dynamic plate to rotate circumferentially, achieving circumferential adaptation of the nozzle angle. Furthermore, the tilt angle adjustment of the dynamic plate on the support plate achieves precise alignment in the pitch direction.

[0016] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3This utility model provides a technical solution: a plasma treatment device for paper cup surfaces, including a frame 1, a support platform 2 on the base plate of the frame 1, a sliding seat 3 driven by a transverse guide rail at the top of the frame 1, the transverse guide rail being a precision linear guide rail, a plasma treatment unit 4 consisting of a plasma generator and an ion nozzle mounted on the sliding seat 3, the ion generator and the ion nozzle being connected by a gas delivery pipe, a rotating mechanism consisting of a rotating bracket 5 and a rotating disk 6 below the sliding seat 3, the top two sides of the rotating bracket 5 being fixed to the bottom two sides of the sliding seat 3 by connecting plates and bolts, a support plate 7 at the bottom of the rotating mechanism, the bottom end of the rotating disk 6 extending outside the rotating bracket 5, and the support plate 7 being vertically welded and fixed to the rotating bracket 5. At the bottom of the tray 6, a dynamic plate 8 with an adjustable tilt angle is provided on the support plate 7. The front end of the dynamic plate 8 has a fixing sleeve 9 for mounting the ion nozzle. This structure drives the sliding seat 3 to move along the top of the frame 1 via a transverse guide rail, adjusting the position of the plasma treatment unit 4 in the paper cup conveying direction to adapt to the processing needs of seams of different lengths. Simultaneously, the sliding seat 3 drives the rotating bracket 5 and the rotating tray 6 below to move laterally as a whole, ensuring the coverage of the processing area. When it is necessary to adjust the nozzle angle to precisely align with the seam line of paper cups of different diameters, a rotating mechanism consisting of the rotating bracket 5 and the rotating tray 6 can be driven. The rotating tray 6 drives the support plate 7 at its bottom to rotate synchronously, thereby changing the spatial orientation of the dynamic plate 8 and realizing the ion nozzle's rotation in the circumferential direction. Angle adjustment: Based on this, the tilt angle of the dynamic plate 8 can be adjusted on the support plate 7 to further refine the emission angle of the nozzle, ensuring that the ion beam acts perpendicularly on the side wall surface of the paper cup with different curvatures. The fixing sleeve 9 is used to securely install the ion nozzle, ensuring its stability during dynamic adjustment. This multi-degree-of-freedom linkage adjustment structure allows the plasma nozzle to flexibly adapt to the processing needs of different sized paper cups in multiple dimensions, including horizontal movement, circumferential rotation, and tilt angle. This solves the problems of processing area offset, uneven processing, and local omissions caused by the fixed position or limited adjustment range of the nozzle in the existing technology when changing cup types. It effectively avoids bonding defects such as bursting and false adhesion caused by these defects, significantly improving the versatility and adjustability of the equipment. To improve the speed and sealing reliability of the finished paper cups, a rectangular notch is provided on the support plate 7. Both sides of the bottom of the dynamic plate 8 are connected to the inner walls of the rectangular notch on both sides of the support plate 7 via rotating shafts. A wedge-shaped push block 12 is provided at the upper inner end of the rectangular notch on the support plate 7. A guide slope matching the surface structure of the wedge-shaped push block 12 is provided on the back of the dynamic plate 8. Vertically distributed push cylinders 10 are installed on one side of the support plate 7. The output end of the push cylinder 10 is fixedly connected to one side of the wedge-shaped push block 12 via a connector. A strip-shaped opening matching the connector of the output end of the push cylinder 10 is provided on one side of the rectangular notch on the support plate 7. An elastic limiting member 11 connects the top of the dynamic plate 8 to the upper end of the rectangular notch on the support plate 7. When the push cylinder 10 is driven by this structure…Its output end drives the wedge-shaped pusher 12 to move up and down along the rectangular recess of the support plate 7 via a connector. When the wedge-shaped pusher 12 descends, it applies an outward force along the guide slope on the back of the dynamic plate 8, causing the dynamic plate 8 to rotate around its bottom pivot, thereby adjusting the tilt angle of the dynamic plate 8. At the same time, the elastic limiter 11 provides the necessary tension and buffer between the top of the dynamic plate 8 and the upper end of the rectangular recess of the support plate 7, ensuring that the dynamic plate 8 can be positioned smoothly and accurately during the adjustment process and remain stable after adjustment. This achieves flexible control of the tilt angle of the dynamic plate 8, thereby realizing the angle adjustment of the ion nozzle installed on the fixed sleeve 9 to meet the surface treatment needs of paper cups of different specifications. The rotating bracket 5 and the rotating disk 6 are both circular structures. The center of the rotating bracket 5 and the rotating disk 6 are connected by a bearing, and a rotating motor is fixedly installed at the center of the top of the rotating bracket 5 by bolts. The output shaft of the rotary motor is connected to the rotary disk 6. This structure drives the rotary disk 6 to rotate smoothly around its central axis relative to the rotary support 5, thereby causing the ion nozzles on the support plate 7, dynamic plate 8, and fixed sleeve 9 to rotate circumferentially. This allows for adjustment of the azimuth angle of the seam position for paper cups of different diameters. Both sides of the fixed sleeve 9 are connected to the outer wall of the dynamic plate 8 via vertical guide rails, and locking rings are welded to both the upper and lower ends of the fixed sleeve 9. This structure allows the fixed sleeve 9 to slide up and down relative to the dynamic plate 8 in the vertical direction, thereby achieving fine adjustment of the height position of the ion nozzles to adapt to the processing needs of paper cups of different heights. At the same time, the locking rings welded to the upper and lower ends of the fixed sleeve 9 can be used with locking bolts or clamp structures to firmly clamp and fix the ion nozzles, preventing positional displacement due to vibration or airflow impact during equipment operation, and ensuring the stability and repeatability of the nozzle installation.

[0018] Working Principle: When using this paper cup surface plasma treatment device, first place the paper cup to be treated on the support platform 2, ensuring the paper cup is in the correct and stable position. Then, the sliding seat 3 is driven by the transverse guide rail to move along the top of the frame 1 to the predetermined position. At this time, the plasma treatment unit 4 installed on the sliding seat 3 is also adjusted to the appropriate working position. Next, according to the specific diameter of the paper cup, the rotary motor is started, driving the bearing between the rotating bracket 5 and the rotating disk 6, so that the rotating disk 6 drives the ion nozzles on the bottom support plate 7, dynamic plate 8 and fixed sleeve 9 to rotate circumferentially, accurately aligning with the paper cup. If further adjustment of the ion nozzle angle is needed, the cylinder 10 is pushed to start working. Its output end drives the wedge-shaped pusher 12 to move up and down along the rectangular notch of the support plate 7 through the connector, causing the dynamic plate 8 to rotate around its bottom axis, thereby achieving fine adjustment of the tilt angle. For paper cups of different heights, the operator can manually or automatically adjust the height of the fixing sleeve 9 through the vertical guide rail to ensure the optimal distance between the ion nozzle and the surface of the paper cup. After everything is ready, the plasma generator is started to generate a plasma beam, which acts on the surface of the paper cup through the ion nozzle to complete the surface treatment process, thus completing a series of tasks.

[0019] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
