Description

Technical Field

[0001] This application relates to the field of corona treatment equipment technology, and more particularly to UV material surface tension pretreatment equipment. Background Technology

[0002] With the explosive growth in the number of testing projects in the UV laboratory, from 5-10 batches per week to 15-25 batches per week, the types of testing materials have also expanded from conventional PET film to various UV-specific substrates such as PE and BOPP. Against this backdrop, the corona generator (2) originally installed on the OnePass equipment in the inkjet testing room has gradually become unsuitable for the new work rhythm due to its inherent usage mode. Looking back at the past operating procedures, the use of this corona generator (2) has obvious shortcomings. When using the OnePass equipment linkage mode, the material to be processed needs to be passed through the entire equipment and the OnePass equipment needs to be running synchronously, or the material needs to be manually pulled through the corona generator. The drawbacks of manual traction are even more pronounced: operators must hold the material at both ends and pass it through the electrode gap of the corona generator (the gap is only 8mm). During this process, the exposed electrodes may generate instantaneous high-voltage arcs (the measured peak voltage reaches 2KVA), and there have been many minor burn accidents. At the same time, the uneven feeding speed (the fastest is 1m / min, the slowest is 0.5m / min) will cause fluctuations in the surface tension of the material (the deviation range is ±5dyne / cm), which directly affects the adhesion of UV inks. These two operating methods are not only cumbersome in terms of process, but also pose certain safety hazards. Their usage has gradually revealed its limitations and brought a lot of trouble to daily work. Utility Model Content

[0003] To address the aforementioned issues, this technical solution provides a UV material surface tension pretreatment device.

[0004] To achieve the above objectives, the technical solution is as follows:

[0005] UV material surface tension pretreatment equipment, including

[0006] The frame, on which a corona machine is mounted;

[0007] The take-up and unwinding mechanism includes a take-up roller, an unwinding roller, a first roller body, and a second roller body, all mounted on the frame.

[0008] The roll material is mounted on the unwinding roller for unwinding, and after passing through the first roller body, the corona generator, and the second roller body in sequence, it is wound up by the take-up roller.

[0009] As described above, the UV material surface tension pretreatment equipment includes a take-up roller comprising a roller shaft, a roller cylinder disposed on the roller shaft, and a roller cover, wherein the roller cover is connected to the end of the roller shaft to fix the roller cylinder on the roller shaft.

[0010] As described above, in the UV material surface tension pretreatment equipment, the take-up roller is provided with a clamping mechanism, which is used to clamp the roll material to wind the roll material onto the roller drum.

[0011] As described above, the UV material surface tension pretreatment equipment includes a roller cylinder comprising a cylinder body and a cylinder cavity.

[0024] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] UV material surface tension pretreatment equipment, including

[0026] A frame 1, on which a corona machine 2 is mounted;

[0027] The take-up and unwinding mechanism includes a take-up roller 3, an unwinding roller 4, a first roller body 5, and a second roller body 6, which are mounted on the frame 1.

[0028] The roll material 8 is mounted on the unwinding roller 4 for unwinding, and passes sequentially through the first roller body 5, the corona generator 2, and the second roller body 6 before being wound up by the take-up roller 3.

[0029] This invention provides a surface tension pretreatment device for UV materials. By integrating the corona treatment machine and the winding and unwinding mechanism into the frame, it achieves automated and continuous processing of roll materials. Operators no longer need to manually pull the material through the narrow electrode gap, which carries the risk of high-voltage arcs, fundamentally eliminating the safety hazard of personnel being burned by high-voltage arcs and greatly improving operational safety.

[0030] The roll material is guided and tensioned by a take-up and unwinding mechanism (take-up roller, unwinding roller, first and second rollers) so that it passes through the treatment area of ​​the corona machine (2) at a constant and uniform speed. This overcomes the problem of large fluctuations in surface tension values ​​(deviation ±5 dyne / cm) caused by uneven feeding speed (0.5-1 m / min) during manual feeding, ensuring the uniformity and consistency of the material surface tension treatment, and providing a stable and reliable pretreatment foundation for the subsequent adhesion of UV inks.

[0031] This equipment achieves fully mechanized continuous operation from unwinding and corona treatment to rewinding, with a processing speed far exceeding that of manual operation. This perfectly meets the new demands of the explosive growth in the number of UV laboratory testing projects (15-25 batches per week) and the diversification of material types (PET, PE, BOPP, etc.), significantly improving work efficiency and avoiding the drawbacks of the original mode that required the linkage of the entire OnePass equipment or cumbersome manual operation.

[0032] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the take-up roller 3 includes a roller shaft 31, a roller cylinder 32 disposed on the roller shaft 31, and a roller cover 33. The roller cover 33 is connected to the end of the roller shaft 31 to fix the roller cylinder 32 on the roller shaft 31. The detachable roller cover design makes the installation and replacement of the roller cylinder quick and convenient, facilitating the unloading and subsequent operations of different batches or types of processed rolls.

[0033] Furthermore, as a preferred embodiment of this solution and not a limitation, the take-up roller 3 is provided with a clamping mechanism 7, which is used to clamp the roll material to wind it onto the roller drum 32. This reliably fixes the starting end of the roll material at the beginning of winding, preventing the roll material from slipping or falling off in the early stages of winding, ensuring a smooth start and continuous stable operation of the winding process, and further improving the automation level and reliability of the equipment.

[0034] Furthermore, as a preferred embodiment of this solution and not a limitation, the roller drum 32 includes a drum body 321 and a drum cavity 322. The clamping mechanism 7 includes an installation port 71 disposed on the drum body 321 and communicating the drum cavity 322 with the outside, and a clamping assembly 72. The clamping assembly 72 is used to press the roll material entering the drum cavity 322 from the installation port 71 onto the inner wall of the drum cavity 322. The end of the roll material enters the drum cavity through the installation port and is pressed by the internal clamping assembly. The outer surface of the drum remains intact and smooth, so that the roll material can be wound flatly on the drum body without being damaged by exposed clamping parts (such as traditional clamps) or affecting the flatness of the winding.

[0035] Furthermore, as a preferred embodiment of this solution and not a limitation, the mounting port 71 includes a first inlet ramp 711 inclined from the side wall of the cylinder 321 toward the cylinder cavity 322, and a vertical surface 712 opposite to the first inlet ramp 711. The inclined first inlet ramp acts as a guide and funnel, making it easier and more accurate for operators to guide the end of the roll material into the narrow mounting port, reducing the difficulty of the material threading operation and improving work efficiency.

[0036] Furthermore, as a preferred embodiment of this solution and not a limitation, the lowest edge of the first inlet slope 711 is lower than the lowest edge of the vertical surface 712. This creates a height difference, which allows the end of the roll material to slide naturally into the cylinder cavity under gravity or slight pushing, further optimizing the ease of threading.

[0037] Furthermore, as a preferred embodiment of this solution and not a limitation, the end face of the cylinder 321 is provided with a second inlet ramp 713 inclined towards the mounting port 71. The second inlet ramp 713 is connected to the two opposite sides of the mounting port 71. This provides another guide ramp from the end face direction, which, together with the first inlet ramp, forms a three-dimensional guide channel, allowing the roll material to be easily introduced into the mounting port from more angles, greatly improving the convenience and error tolerance of operation.

[0038] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the clamping assembly 72 includes a clamping roller 721 disposed in the cylindrical cavity 322, and an adjusting roller 722 meshing with the clamping roller 721. The adjusting roller 722 rotates to move the clamping roller 721 to fit tightly against the inner wall of the cylindrical cavity 322. Through gear meshing transmission, the clamping roller can be driven to perform clamping or releasing actions with a simple rotational motion. This mechanism has a large and stable clamping force, is simple and reliable to operate, and maintains a stable clamping state after clamping due to its mechanical self-locking characteristic.

[0039] Furthermore, as a preferred embodiment of this solution, and not a limitation thereof, an arc-shaped track 723 is provided on the inner end face of the cylinder 321, and a rotating shaft 724 is provided on the clamping roller 721. When the adjusting roller 722 rotates, it drives the clamping roller 721 to rotate, and at the same time, the rotating shaft 724 drives the clamping roller 721 to move along the arc-shaped track 723 towards or away from the inner wall of the cylinder cavity 322. This limits the movement trajectory of the clamping roller, making its movement more precise and stable, preventing swaying or jamming during movement, ensuring the smoothness and reliability of the clamping action, and at the same time ensuring that the clamping force can be evenly applied to the roll material.

[0040] Furthermore, as a preferred embodiment of this solution and not a limitation, the end face of the cylinder 321 is provided with an adjusting member 725 that rotates synchronously with the adjusting roller 722, and a locking member 726 that is threadedly engaged with the adjusting member 725. The adjusting member provides an operating end that facilitates the application of force, allowing the operator to rotate it by hand or with tools; while the locking member, through its threaded engagement with the adjusting member, presses against the cylinder to generate a self-locking effect, firmly locking the position of the adjusting roller and preventing it from reversing due to vibration or other reasons during equipment operation, thus preventing the clamping force from loosening and ensuring long-term reliability of the clamping.

[0041] The above description is only a preferred embodiment of this application and is not intended to limit the scope of implementation of this application. Any other embodiments whose principles and basic structures are the same as or similar to those of this application are within the protection scope of this application.
